Abstract

[Problem] To address the problem of developing a novel fluid pressure transfer method designed in such a manner as not to produce residue or roughness on an object to be transferred, by maintaining a fluid discharge position at a roughly constant position when pulling up the object to be transferred from within a transfer fluid. [Solution] The present invention involves a fluid pressure transfer method in which an object to be transferred is pressed from above a transfer tank, and an appropriate transfer pattern is formed on the surface of the object to be transferred, said fluid pressure transfer method being characterized in that, when lifting up the object to be transferred, the object to be transferred is lifted up in an inclined state along a design surface or a virtual fluid discharge line that smoothly connects design surfaces, thereby discharging the object to be transferred while maintaining a fluid discharge position on a design surface of the object to be transferred at a roughly constant position. The fluid pressure transfer method is further characterized in that a fluid discharge angle β is set within a range of 25 degrees to 55 degrees, and the fluid discharge orientation of the object to be transferred is controlled in such a manner that an operation for discharging the object to be transferred can be smoothly performed.

Description

Hydraulic transfer method

In the present invention, a transfer film, which is formed with an appropriate transfer pattern (surface ink layer) in advance by transfer ink, is supported in a floating manner on the liquid surface, and is immersed in the transfer liquid while pressing the transfer target. The liquid pressure is used to transfer the transfer pattern on the film to the transferred material using the hydraulic pressure, and the liquid discharge position of the transferred material is raised to a substantially constant position when it is pulled up from the transfer liquid. Thus, the present invention relates to a novel hydraulic pressure transfer method that prevents the occurrence of deficiency defects or sagging defects on the design surface.

On the water-soluble film (supporting sheet), a transfer film formed by applying a suitable non-water-soluble transfer pattern in advance is floated in a transfer tank (transfer liquid), and the transfer film (water-soluble film) is transferred to the transfer liquid (primarily In a state wetted with water), the transferred object is pushed into the liquid in the transfer tank while contacting the transfer film, and the transfer pattern on the film is transferred and formed on the surface of the transferred object using the liquid pressure. Hydraulic transfer is known. As described above, a transfer pattern is formed (printed) in advance on the water-soluble film with ink on the transfer film, and the transfer pattern ink is in a dry state. For this reason, when transferring, it is necessary to apply an activator or thinner to the transfer pattern on the transfer film to return the transfer pattern to the same wetness, that is, adhesion, just after printing. It is called.

After the transfer, the transfer object taken out from the transfer tank is dried after the semi-dissolved water-soluble film is removed by washing with water or the like to protect the decorative layer transferred and formed on the transfer object. For this reason, it was often used as a top coat. However, in such conventional hydraulic pressure transfer, solvent-based clear paint is first used for the top coat, so there is a problem that the environmental load is high, and it takes a relatively long time for top coat defects and paint drying. The cost of the entire hydraulic transfer is incurred due to the cost and energy required.

For this reason, a method has been devised in which a transfer pattern having a surface protection function is formed on a transfer object during hydraulic pressure transfer, and this is cured after transfer to form a decorative layer, thereby omitting the top coat. (For example, refer to Patent Documents 1 and 2).
Among these, Patent Document 1 uses a cured resin composition (liquid) as an activator while using a conventional transfer film in which only a transfer pattern is formed on a water-soluble film, and irradiates the transferred object with ultraviolet rays after transfer. This is a technique for curing the cured resin composition (surface protective layer) that is steadily integrated with the transfer pattern.
Further, Patent Document 2 uses a transfer film in which a curable resin layer is formed between a water-soluble film and a transfer pattern, and the transferred object is irradiated with active energy rays such as ultraviolet rays or heated on the transfer pattern. This is a method of curing the curable resin layer.

By the way, in the hydraulic transfer in which a transfer pattern having a surface protection function is formed, when the transferred object is immersed (during transfer), the transferred object breaks through the transfer film floating on the liquid surface and is immersed in the liquid. Since it becomes operation | movement, the film which remained on the liquid level after immersion becomes an unnecessary thing which is no longer used for transfer (this is made into a liquid level residual film). In addition, when the transfer target breaks through the transfer film on the liquid surface, fine film residue (for example, string waste in which a water-soluble film and ink are mixed) is dispersed and released in a large amount in the transfer liquid. Therefore, this stays in the transfer liquid. Furthermore, since the immersion (transfer) of the transfer object is usually performed in a state where it is attached to the jig, the excess film attached to the jig or the transfer object is peeled off and released in the liquid during the immersion. Sometimes there was. For this reason, such a liquid level residual film, film residue, surplus film, etc. may adhere to the design surface of the transfer target pulled up from the transfer liquid (these are unnecessary ones remaining on the transfer liquid level or in the liquid). Therefore, these are collectively referred to as “contaminants” in this specification).

Furthermore, for example, as shown in FIG. 25 (a), when the transfer target W has an opening Wa on the design surface S1, water of the water-soluble film is formed in the opening Wa when the transfer surface W is pulled up from the liquid surface. The thin film M is often stretched by the melted material, and the film A is flipped and bubbles A adhere to the design surface S1 of the transfer target W. Alternatively, the transfer is performed from the protrusion of the transfer target W or the upper edge of the opening Wa. When the liquid L falls on the liquid surface, bubbles A may be generated on the liquid surface, which may adhere to the design surface S1. That is, in FIG. 25 (a), the thin film M is initially stretched on the frame of the jig J, and bubbles A of the rupture residue drift on the transfer liquid surface, moving the liquid surface in the liquid discharge area P2 (raising the transfer target W). The bubble A is taken into the thin film M stretched on the opening Wa of the transfer target W, and then the rupture residue of the thin film M floats on the liquid surface as the bubble A and indirectly. In particular, it adheres to the design surface S1 or directly as a bubble A is transmitted through the surface of the transfer target W and adheres to the design surface S1, resulting in the state shown in FIG.

Then, when the curing process is performed by irradiation with active energy rays or / and heating in this state, for example, as shown in FIG. Due to refraction or the like, pattern distortion of the decorative layer (transfer pattern / surface protective layer), a phenomenon that the pattern falls off (so-called pinhole defect), or the like occurs only at the portion concerned. Of course, such pattern distortion and drop-off are not limited to the case where the bubble A adheres to the design surface S1, but also when the liquid surface residual film, film residue, excess film, or other foreign matter adheres to the design surface S1. This is a phenomenon (problem) that can occur. Here, reference numeral f in the figure indicates a decorative layer transferred mainly to the transfer target W (design surface S1) or the like. Therefore, in the hydraulic transfer that forms a transfer pattern having a surface protection function at the time of the hydraulic transfer, the liquid level residual film, the film residue, the surplus film, the bubble A, and the like are not adhered to the design surface S1 as much as possible. (It is collectively referred to as “poor defect” that bubbles A and foreign substances adhere to the design surface).
In addition, because the article (hydraulic transfer product) that has undergone pattern distortion or dropout is once cured, irregularities due to pattern distortion or dropout stand out and transfer cannot be performed again (reproduction). Therefore, such a defective product significantly deteriorates mass productivity, and a fundamental solution for reducing the defective rate itself has been strongly desired.

In addition, after the transfer, the transfer pattern including the ink attached to the design surface S1 and the thick film curable resin is still in the transfer target W until irradiation with active energy rays and / or curing by heating. Since it is in an uncured state, it is easy to flow. Accordingly, when a load is applied to the design surface S1 due to the rotational operation of the transfer target W in the transfer liquid, the transfer speed, the ripples of the transfer liquid surface, the vibration of the transfer target W during liquid discharge or immediately after liquid discharge, and the like. The transfer pattern containing the ink that has just adhered to the design surface S1 and the thick curable resin flows, and the design surface is likely to be damaged (this is considered to be a sagging defect). As a representative example of the sagging failure, for example, as shown in FIG. 26, there is a liquid surface wave phenomenon (negative pressure attack) that occurs when the design surface S1 comes out in parallel with the transfer liquid surface.

By the way, FIG. 27 shows the liquid discharge operation when the transfer target W is pulled up at a certain inclination angle from the transfer tank 2 in which no liquid flow is formed near the liquid surface (so-called batch type). In this case, as the transfer target W is pulled up, the liquid discharge position is as shown in FIGS. 27A to 27C, as shown in FIGS. 27A to 27C. On the left side, you can see how it moves gradually. The “liquid discharge position” is a liquid discharge point (point) of the transfer target W on the design surface S1 when the transfer target W to be discharged is viewed from the side, and the design surface S1 and the transfer liquid. It can be said that it is an intersection with the surface.
In such a pulling-up method (in a pulling-up method in which the liquid discharge position is gradually moved toward the liquid discharge rear end side), the transferred object W itself takes on an action like a scum that scrapes water (liquid). Is transferred (guided) to the rear end side of the liquid discharge along the inclination of the transfer target W. Such a flow of the transfer liquid L is a movement (flow) that relatively falls in the transfer tank 2 while bypassing the liquid discharge rear end side of the transfer target W, and this is inclined waterfall. . The inclined falling water forms a stirring flow that directs the transfer liquid L in the transfer tank 2 toward the design surface S1 (liquid discharge position) of the transfer target W, as shown in FIGS. 27 (b) and (c). To do. For this reason, the transfer liquid L due to the stirring flow is brought close to the transfer target W (design surface S1), and foreign matters such as film residue existing in the transfer liquid are easily attached (debris failure). Of course, due to such a stirring flow, sagging defects are likely to occur on the design surface S1.
In addition, when stirring flow due to sloping falling water occurs, it takes time for the liquid surface to stop (stable), so the liquid surface does not stabilize (contains) at the same tact time as conventional hydraulic transfer, and continuously. As the transfer was performed, the adverse effects (debris failure / sagging failure) due to the stirring flow tended to increase.

In recent years, there has been a demand for hydraulic transfer in a short time to reduce printing costs, and in order to improve productivity and promote swelling of the transfer film, a transfer film that is easy to extend thinly is desired. The environment is becoming more prone to the above-mentioned deficiency defects and sagging defects.
In addition, in the case of a UV curable transfer film, if a deficient defect (bubble adhesion) or a sagging defect occurs on the design surface S1 due to a stirring flow or the like, UV light diffuses in that part, and the part is uncured. The problem (problem) that becomes is not negligible (previously, it was a low-speed transfer and the transfer film was not so thin, so it was not assumed).
For this reason, the present applicant has deepened the recognition that it is necessary to review from the liquid discharge operation of the transferred body in order to prevent deficiency defects and sagging defects, while maintaining the liquid discharge position substantially constant. This has led to the idea that pulling up the transfer medium prevents the stir flow as much as possible.

Needless to say, there has been no technical idea considering the falling water at the time of pulling up (see, for example, Patent Document 3). However, this Patent Document 3 is intended only for a large transferred object, and when such a large transferred object is pulled up in parallel with the water surface (liquid surface), the resistance by water is extremely large. In order to prevent this, the member to be transferred is inclined and pulled up, and there is no idea of maintaining the liquid discharge position constant.
In this way, in the past, it was the fact that there was not much interest in liquid discharge operation, this is that hydraulic transfer was performed and completed at the same time as immersion, and transfer was already completed at the time of liquid discharge Seems to be greatly related. In other words, the movement and posture control of the transferred object during immersion, where hydraulic transfer is performed, is a matter that is directly related to the quality and finish of the transfer, so much development and research has been done, but transfer has already been done. The technical philosophy of reviewing the entire hydraulic transfer from the time of completion of brewing was a sort of philosophy that goes back in time, so this brewing operation is mostly focused on development and research. It is thought that there was not.

As the transfer film, either a water-soluble film formed with a transfer pattern only in a dry state is applied, or a film having a curable resin layer between the water-soluble film and the transfer pattern is applied. In addition, when a film in which only a transfer pattern is formed on a water-soluble film is applied in a dry state, a liquid curable resin composition is used as an active agent.
As a result, a transfer pattern having a surface protection function is formed on the transfer object during hydraulic transfer, and this is cured by irradiation with active energy rays after transfer and / or heating. It is.

The above-described problems can be solved by using the configuration of the invention described in each of the claims.
According to the first aspect of the present invention, the liquid discharge position is gradually moved toward the liquid discharge rear end side in order to pull up the transfer body from the transfer liquid in an inclined posture while maintaining the liquid discharge position at a substantially constant position. Compared with the method of pulling up, it is possible to suppress the stirring flow in the transfer liquid, and it is possible to prevent the sagging defect and the dregs defect on the design surface due to this. That is, in the pulling method in which the liquid discharge position gradually moves toward the liquid discharge rear end side, the transfer liquid positioned on the back surface side (upward side) of the inclined transfer target body follows the inclination along with the liquid discharge. This causes a stir flow (liquid wave) in the transfer tank, which causes film residue and other contaminants in the transfer liquid on the design surface facing the transfer liquid side (downward). It was easy to adhere (scrap defect), and the ink that had just adhered to the design surface flowed, and the sagging failure that caused the design surface to sag was likely to occur. It can be prevented.

According to the second aspect of the present invention, for example, when the transferred body has a bending point on the design surface, if the transferred body is pulled up along the design surface in an attempt to maintain the liquid discharge position, The transferred body is mainly rotated at the bending point, and may cause a sagging defect or a defective chip. However, in such a case, in the present invention, a liquid discharge virtual line that smoothly connects the design surfaces is assumed, and the transferred object is pulled up along this line, so that the transferred object is continuously lifted even at the bending point. And the above problems can be avoided.

According to the invention described in claim 3, depending on the transfer object, even if the transfer object is pulled up along the design surface or the liquid discharge virtual line, a series of operations of the transfer object from immersion to liquid discharge is smooth. It may not be carried, or it may become easy to cause a sagging defect or a defective defect. However, in such a case, in the present invention, the liquid discharge angle of the transferred body is controlled in an appropriate state by setting the liquid discharge angle of the transferred body in the range of 25 to 55 degrees. While avoiding, it is possible to pull up while maintaining the liquid discharge position substantially constant.

According to the invention described in claim 4, in order to form (act) a design surface separation flow in a direction away from the design surface with respect to the transferred material being discharged, impurities such as bubbles and film residues are formed. Is difficult to adhere to the design surface, and a beautiful transfer product (transfer object) can be obtained. In addition, since bubbles and impurities are difficult to adhere to the design surface, the transfer pattern itself can be precisely transferred, and pattern distortion and deformation hardly occur.

According to the fifth aspect of the present invention, the distance between the liquid discharge position and the transfer liquid recovery port (discharge port) for forming the design surface separation flow is substantially constant while the transfer target is pulled up from the transfer liquid. Therefore, the design surface separation and flow with the same force can be applied to the design surface at all times during the liquid discharge operation, and it is possible to more effectively prevent dregs and sagging defects.

According to the invention described in claim 6, the method for forming the design surface separation flow becomes specific, and the design surface separation flow is surely applied to the design surface of the transferred material discharged from the transfer liquid. Can act. Although the action and purpose are different, the overflow tank itself has been used for this type of transfer tank (hydraulic transfer technique), so from the viewpoint of designing the hydraulic transfer apparatus, It is also easy to adopt from the viewpoint of implementing the hydraulic transfer method.

Further, according to the invention described in claim 7, fresh water (clean water containing no contaminants or purified water from which contaminants have been removed from the recovered solution) supplied from below the overflow tank for forming the design surface separation flow ) Is used to generate a design surface separation flow, so that a much more beautiful transfer product (transfer object) can be obtained as compared with the case where the collected transfer liquid is reused almost as it is as the design surface separation flow.

Further, according to the invention described in claim 8, since the siphon-type discharge portion is provided on the back side of the new water supply port for supplying new water downward toward the liquid discharge area, the film stays in the transfer liquid, particularly the middle layer water. After transferring foreign matters such as debris to the bottom (bottom) of the transfer tank (after flowing), it can be sucked up from here and effectively recovered. For this reason, it is possible to prevent the contaminants from rising to the upper liquid discharge area, and the liquid discharge area can be maintained in a cleaner state. In addition, even if the transfer liquid cannot be sucked up by the siphon-type discharge unit, fresh water can be drawn into the transfer tank and a flow toward the suction port (downward flow) can be formed. A stream that facilitates precipitation separation can be formed.

According to the ninth aspect of the present invention, a tapered inclined plate is provided at the bottom end of the treatment tank, and the suction port of the siphon discharger is provided so as to face the uppermost end of the inclined plate. From the fresh water supplied downward toward the liquid area, it is possible to more efficiently form the suction flow by the siphon discharger. That is, the flow of the transfer liquid that rises along the inclination of the inclined plate can be efficiently taken into the suction port of the siphon-type discharge portion while maintaining its momentum, and it becomes easier to form the suction flow from the fresh water. Is.

According to the invention described in claim 10, since the fresh water that is supplied upward and downward from the fresh water supply port is also supplied in parallel to the liquid discharge area, this is upward and downward. It promotes the action of fresh water supplied to the water (prevents interfering with each other), and contributes to the expansion of the clean zone in the drainage area.

According to the invention of claim 11, since the punching metal is provided in the discharge port portion of the new water supply port, the new water supplied from here to the transfer tank is uniformly discharged from a relatively wide range. Can be prevented from being partially fed straight.

Further, according to the invention of claim 12, since the flange for increasing the flow velocity is formed in the overflow tank that forms the design surface separation flow, the contaminants that float near the liquid surface on the design surface side mainly in the liquid discharge area And bubbles on the liquid surface can be more reliably collected.

According to the invention described in claim 13, since the transferred object is held by the manipulator and the operation (movement) is performed from immersion to liquid discharge, the degree of freedom of movement (movement) of the transferred object is increased, and the immersion is performed. The operation of the transferred object from the liquid to the liquid discharge becomes smoother, and the liquid discharge position can be maintained more accurately.

According to the invention described in claim 14, a so-called continuous mode is adopted in which a liquid flow is formed near the liquid surface of the transfer tank, and continuous hydraulic transfer is performed while supplying a transfer film from the upstream side. Therefore, a new hydraulic pressure transfer method of pulling up the transferred material from the transfer liquid while maintaining the liquid discharge position almost constant can be performed continuously (making the production system at a specific mass production level a reality). .

According to the invention of claim 15, a transfer pattern having a surface protection function is formed on the transfer target body by hydraulic transfer, and this is cured by subsequent active energy ray irradiation and / or heating. The transfer target pulled up from the transfer liquid has a deficiency in which dust such as film residue adheres and bubbles, or a transfer pattern containing ink and a thick film curable resin immediately after adhering to the design surface. It is important not to cause defects, and such hydraulic transfer can be performed at a very low defect rate.

The mode for carrying out the present invention includes one described in the following embodiments, and further includes various methods that can be improved within the technical idea.
In the description, first, the transfer film F suitably used in the present invention will be described, and then the entire configuration of the hydraulic transfer device 1 will be described.

First, the transfer film F suitably used in the present invention will be described. In the present invention, at the time of hydraulic transfer, it is preferable to transfer only the transfer pattern to the transfer target W, and particularly to transfer a transfer pattern having a surface protection function (in this specification, such a transfer pattern is used). The transfer pattern is referred to as a “transfer pattern also having a surface protection function”), which is because a top coat which has been conventionally applied after transfer is not necessary. That is, in the hydraulic transfer that also provides the surface protection function, the transferred pattern W formed by the hydraulic transfer is cured by irradiating the transferred object W after transfer with active energy rays such as ultraviolet rays and electron beams, The surface can be protected. Of course, after transferring the transfer pattern having the surface protection function, it is possible to apply a top coat.
Therefore, as the transfer film F, a film in which only a transfer pattern with a transfer ink is formed on a water-soluble film (for example, PVA; polyvinyl alcohol), or a curable resin between the water-soluble film and the transfer pattern. Application of a film in which a layer is formed is preferable, and in particular, when a transfer film F in which only a transfer pattern is formed on a water-soluble film is used, a liquid cured resin composition is used as an activator. Here, the cured resin composition is preferably a solventless ultraviolet or electron beam curable resin composition containing a photopolymerizable monomer.

Here, the transfer patterns include wood grain patterns, metal (glossy) patterns, stone patterns that simulate the surface of rocks such as marble patterns, fabric patterns that simulate cloth and cloth-like patterns, Various patterns such as a pattern such as a tiled pattern and a brickwork pattern, a geometric pattern, a pattern having a hologram effect, and the like may be used. The geometric pattern includes not only figures but also patterns with letters and photographs.

When the surface of the transfer target W is defined, first, the transfer surface on which the decoration layer is formed is a design surface S1, and this design surface S1 can be said to be a surface that requires precise transfer. Is a surface facing the transfer film F (transfer pattern) floated on the transfer liquid surface. Here, as described above, in particular, when a transfer pattern having a surface protection function is formed at the time of hydraulic transfer, the liquid level residual film F ′, surplus film, film residue, This is to prevent bubbles A and the like from adhering as much as possible (preventing deficient defects and freezing defects).
On the other hand, the surface on which the decorative layer is not formed (the surface that does not require hydraulic transfer) is defined as a decoration-unnecessary surface S2, on which the film residue, bubbles A, etc. may adhere ( For example, the transfer pattern wrapping around from the design surface S1 side may be transferred in a distorted state).
Therefore, in other words, the design surface S1 becomes a part visually observed in a state where the transferred object W (hydraulic transfer product) is finally assembled as an assembly or the like as a finished product, and the decoration unnecessary surface S2 is It is a portion that is not visually observed in the assembled state and is often the back side of the design surface S1.

Next, the hydraulic transfer device 1 will be described. As shown in FIG. 1 and FIG. 2 as an example, the hydraulic transfer apparatus 1 includes a transfer tank 2 that stores a transfer liquid L, a transfer film supply apparatus 3 that supplies the transfer film F to the transfer tank 2, and a transfer film F. Is activated (applied) from the upper side of the transfer film F suspended and supported in the transfer tank 2, and the transferred object W is introduced (immersed) in an appropriate posture and discharged ( And a transfer object transport device 5.
Further, the transfer tank 2 transfers a film holding mechanism 6 that holds both sides of the transfer film F supplied onto the transfer liquid surface, and a liquid surface residual film F ′ that is no longer necessary after the transfer target W is immersed. The liquid level residual film recovery mechanism 7 that collects (discharges) from the liquid and the liquid discharge area purification mechanism 8 that mainly purifies the liquid discharge area (mainly the decoration-unneeded surface S2 side (design surface S1) And the design surface purification mechanism 9 that purifies the design surface S1 side of the transfer target W that floats in the liquid discharge area, and moves away from the transferred transfer film F and flows onto the transfer liquid surface. It comprises an extension reduction preventing mechanism 10 for preventing the extension of the transfer film F supplied onto the transfer liquid surface by removing the activator component K. Here, in the present invention, when the transfer target W is pulled up from the transfer liquid L, the main feature is that the transfer position is lifted while maintaining the liquid discharge position substantially constant. Hereinafter, each component will be described.

First, the transfer tank 2 will be described. The transfer tank 2 is a part that floats and supports the transfer film F in performing the hydraulic transfer, and the processing tank 21 that can store the transfer liquid L at a substantially constant liquid level (water level) is a main constituent member. For this reason, the processing tank 21 has a bottomed shape in which the top surface is opened and the front, rear, left and right are surrounded by wall surfaces, and in particular, reference numerals 22 are attached to both side walls constituting the left and right sides of the processing tank 21.
Here, an area (incident range) where the object to be processed W is poured into the transfer liquid L in the processing tank 21 is defined as an immersion area P1, and an area (exit area) where the object W is pulled up from the transfer liquid L is discharged. This area is designated as area P2. Incidentally, in the hydraulic transfer, since the transfer is executed and completed simultaneously with the immersion of the transfer target W, the immersion area P1 can be said to be a transfer area (transfer position). In addition, the phrase “area” is mainly used in the above names. Usually, the transfer position is moved back and forth depending on the type and state of the transfer pattern of the transfer film F, and has a certain extent. In order to transfer the transfer film F (transfer pattern) to the design surface S1, the immersion / extraction of the transfer target W is at a certain angle (a certain range or width) with respect to the liquid surface. This is because it is often performed. Incidentally, the immersion angle α is not always maintained constant from the start of the immersion of the transferred object W until the immersion of the transferred object W. This is the same for the liquid discharge angle β, and the transferred object W starts to discharge. It is not always maintained constant until the liquid is discharged.
In this embodiment, while the transfer target W is immersed in the transfer liquid L, a film remaining on the liquid surface (an unnecessary liquid surface remaining film F ′ that is not used for transfer) is transferred to the transfer tank 2. In order to divide in the longitudinal direction (liquid flow direction), the interval between the immersion area P1 and the liquid discharge area P2 is provided with a certain distance. The liquid level residual film F ′ divided in the longitudinal direction of the transfer tank 2 is then moved (sent) to both side walls 22 of the transfer tank 2 and discharged (collected) from the transfer tank 2 from here. Is.

Further, in the processing tank 21, for example, a liquid flow of the transfer liquid L from the film supply side (upstream side) toward the liquid discharge area P2 (downstream side) can be formed in the vicinity of the liquid surface (surface layer portion). . Specifically, an overflow tank (an

overflow tank

82, 92, 97, etc., which will be described later) is provided near the downstream end of the transfer tank 2, and a part of the transferred liquid L is transferred after purification. The liquid flow is formed near the liquid surface of the transfer liquid L by circulating supply from the upstream portion of the tank 2. In order to purify the collected transfer liquid L, for example, a purifier such as a sedimentation tank or filtering removes extraneous films and film residues, etc., dispersed and retained in the transfer liquid L from the collected liquid (suspension). There is a method of removing.

Moreover, it is possible to provide, for example, a conveyor 61 as the film holding mechanism 6 inside the both side walls 22 of the processing tank 21, which holds both sides of the transfer film F supplied on the liquid surface. Thus, the transfer film F is transferred from the upstream side to the downstream side at a speed synchronized with the liquid flow of the transfer liquid L. Of course, since the transfer film F (especially water-soluble film) supplied onto the transfer liquid surface gradually spreads in four directions (becomes extended) after the landing, the film holding mechanism 6 (conveyor 61). Is also responsible for regulating the elongation of the film from both sides. That is, the film holding mechanism 6 (conveyor 61) is responsible for transferring the transfer film F to at least the immersion area P1 (transfer position) in a state where the elongation of the transfer film F is maintained almost constant. At the transfer position, the elongation of the transfer film F is maintained at the same level every time, and continuous fine transfer can be performed.
Thus, the film holding mechanism 6 (conveyor 61) is not only responsible for the transfer action of the transfer film F but also for maintaining the film elongation at the transfer position constant (action for regulating the elongation). In the present specification, these are collectively referred to as “film holding action”. Incidentally, in this embodiment, the holding action of the film is canceled at the portion where the liquid level residual film F ′ is recovered, and details thereof will be described later.

As shown in FIG. 5 as an example, the conveyor 61 as the film holding mechanism 6 is formed by winding an endless belt 63 around a plurality of pulleys 62, and the belt 63 contacts both sides of the transfer film F. And a track portion that holds the film (referred to as an “outward belt 63G” for feeding the film in the downstream direction at the same speed as the liquid flow while holding the film) and a position near the side wall 22 on the outside thereof. It is divided into a return path portion (this is referred to as “return path belt 63B”).
Of the plurality of pulleys, the pulley provided on the film supply side (upstream side) is referred to as a start pulley 62A, and the pulley provided in the terminal portion (the overflow tank side for collecting the liquid level residual film) is referred to as a terminal pulley 62B. Further, the intermediate pulley 62C that supports the forward belt 63G from the side in the middle portion of the start pulley 62A and the end pulley 62B is provided (two in this case).
Incidentally, in this embodiment, driving by a motor or the like is input to the terminal pulley 62B.

In the start pulley 62A, the end pulley 62B, and the relay pulley 62C, the rotation shaft 64 is set substantially in the vertical direction, and the width direction of the forward belt 63G that bears the film holding action is the depth (height) of the transfer liquid L. This is because even if the liquid level in the transfer tank 2 changes, the width of the belt 63 can be used, and the entire conveyor 61 need not be moved up and down. Yes (structure that can easily cope with liquid level change in the transfer tank 2).
On the other hand, the return belt 63B is a portion where the relay pulley 62C is provided, and is routed so that a part of the track hangs downward (in other words, a folded state), and the length of the suspending portion is appropriately changed to change the belt 63. The tension applied to the whole is adjusted (for this reason, this hanging portion is referred to as a tension adjusting portion 63C).

The tension adjusting unit 63C includes a total of three pulleys, a position fixing pulley 62D provided on both sides of the relay pulley 62C and a vertically moving pulley 62E provided below the pulley. In actual tension adjustment, for example, a conveyor When it is desired to shorten the plan view dimension of 61, that is, the apparent total length from the start pulley 62A to the end pulley 62B, the vertical movement pulley 62E is lowered to extend the downward folding length of the tension adjustment section 63C. The apparent planar size of the conveyor 61 is shortened without changing the overall length of the belt 63.

Further, the rotation shafts 64 of the position fixing pulley 62D and the vertically moving pulley 62E constituting the tension adjusting unit 63C are set in a horizontal state substantially orthogonal to the side wall 22 of the transfer tank 2. Therefore, in the tension adjusting portion 63C (hanging portion), the width direction of the belt 63 is set so as to be substantially horizontal, and the posture of the belt 63 is changed (twisted) by 90 degrees in the return path portion. That is, the belt 63 is twisted by 90 degrees at the track portion from the end pulley 62B to the position fixing pulley 62D and the track portion from the position fixing pulley 62D to the start end pulley 62A in the return belt 63B.
Incidentally, in FIG. 5, two tension adjusting portions 63C are provided, but this may be omitted, may be one, or may be three or more.

Note that such a film holding mechanism 6 (conveyor 61) is preferably configured such that the distance (width dimension) between the left and right forward belts 63G can be freely adjusted in consideration of the various width dimensions of the transfer film F. This will be described below. As such a configuration (width dimension adjusting function), for example, as shown in the enlarged view of FIG. 5, the arm bar 65 that rotatably supports the relay pulley 62 C can be protruded (expandable) with respect to the side wall 22 of the transfer tank 2. ) Is provided (so-called telescopic type). The arm bar 65 can be fixed at any position (with a protruding dimension) by a clamp 66 or the like.
In this embodiment, the start pulley 62A is also provided so as to protrude in the width direction of the transfer tank 2 by the same method. Incidentally, even when the distance between the left and right forward belts 63G is changed in accordance with the transfer film F, adjustment of the tension adjusting unit 63C, that is, the vertical movement pulley 62E is moved up and down to adjust the tension of the entire belt 63. .
As another method of providing the relay pulley 62C and the start end pulley 62A so as to protrude from the side wall 22 (transfer tank 2), an arm bar 65 that supports the

pulleys

62C and 62A is rotated around the side wall 22 of the transfer tank 2. A method is also conceivable in which the arm bar 65 is provided so as to be freely movable and fixed at an arbitrary rotational position (angle) by a clamp 66 or the like (so-called swing type). Of course, it is also possible to apply such a telescopic type and a swing type in combination in any place.
In this embodiment, the belt 63 is used as the film holding mechanism 6. However, it is also possible to apply a chain, a relatively thick rope or wire, or the like.

In addition, a blower 26 is provided above the film supply side (upstream side) of the processing tank 21, thereby achieving uniform extension around the transfer film F and progressing toward the downstream side of the transfer film F. It is a supplement.
Here, the air blow by the blower 26 is characterized in that the wind is directly applied (struck) to the transfer film F. In other words, the blower 26 is a method of blowing air to the transfer film F itself, and has the idea of forcibly spreading (extending) the transfer film F around by the force of wind.
Moreover, since the air blower 26 assists the transfer operation | movement to the downstream of the transfer film F, the ventilation direction is one direction which goes only from the upstream to the downstream. Of course, the mounting position of the blower 26 is also set to the center position (width center) of the transfer tank 2.
Further, since the blower 26 directly applies wind to the transfer film F, the air volume is set to be relatively strong (large), and the accompanying ripples may reach the transfer position (immersion area P1). Conceivable. Therefore, in order to prevent this, a wave vanishing plate or the like is provided between the blower 26 and the transfer position in the transfer tank 2 to stabilize the transfer liquid surface, particularly the liquid surface at the transfer position. preferable.
Here, the transfer tank 2 in which the liquid flow is formed near the liquid surface has been described. However, it is possible to apply the transfer tank 2 in which no liquid flow is formed in the vicinity of the liquid surface.

Next, the liquid level residual film recovery mechanism 7 will be described. The liquid level residual film recovery mechanism 7 is a mechanism for recovering the liquid level residual film F ′ remaining on the transfer liquid level after the transfer target W is immersed, whereby the liquid level residual film F ′ is removed from the liquid discharge area P2. Is not allowed to reach. That is, the transfer film F is in a pierced state (here, an oval hole is opened), for example, as shown in FIG. The film is immersed in the liquid together with the transfer target W and is attached and transferred to the design surface S1 by the liquid pressure, but the film remaining on the liquid surface (the film floating in the open state) is used for transfer. Therefore, it becomes an unnecessary part (this is the liquid level residual film F ′). If such a liquid level residual film F ′ is left as it is, it will cause the transfer liquid L to become dirty, and if the liquid level residual film F ′ reaches the downstream liquid discharge area P2, it will be lifted from the transfer liquid. In this embodiment, the liquid level residual film F ′ is collected as soon as possible and reliably after transfer because it adheres to the transfer body W (design surface S1). Specifically, first, the liquid level residual film F ′ is divided in the longitudinal direction of the transfer tank 2, that is, in the liquid flow direction, and is moved to both side walls 22 of the transfer tank 2 and pushed out from here. To be discharged.

For this reason, the liquid level residual film recovery mechanism 7 includes a dividing unit 71 that divides the liquid level residual film F ′ in the liquid flow direction, and a discharge unit 72 that discharges outside the tank at the side wall 22 portion of the transfer tank 2. These are provided and will be described below.
First, the dividing means 71 will be described. The dividing means 71 quickly divides (branches) the liquid level residual film F ′ after the transfer of the transfer target W, that is, after the transfer. The air blowing method that can do is adopted. Specifically, as shown in FIG. 1, as an example, a blower 73 is provided on one side wall 22 of the processing tank 21, and air is applied to the liquid level residual film F ′ on the liquid level from here. Here, in the above description, it is simply described as “blower (73)”, but this term includes an extension duct, a nozzle and the like connected to the fan.
In the above description, the liquid level residual film F ′ has been described as being quickly divided, but the dividing action (here, the air volume) of the dividing means 71 is transformed into the transfer film F at the transfer position (immersion area P1) ( Since the transfer itself cannot be precisely performed if an adverse effect such as a pattern distortion due to a return wave) or a stress is generated, the range of action of the dividing means 71 does not adversely affect the transfer position (for example, Provided at a certain distance). In other words, the air volume (wind power) of the blower 73 as the dividing means 71 is set to be relatively weak in consideration of having no adverse effect on the transfer position. Therefore, it is preferable that the blower 73 as the dividing means 71 can be freely moved along the longitudinal direction of the transfer tank 2 according to the back-and-forth movement of the transfer position, thereby preventing the transfer position from being adversely affected. It is easy to set an appropriate position to exert the dividing action.

Here, the division state of the liquid level residual film F ′ by the blower 73 will be described. The liquid level residual film F ′ is divided into left and right by the air blown from the blower 73. In particular, a point at which the division starts in the liquid level residual film F ′ is defined as a division start point P3. Further, the liquid level residual film F ′ is divided into a substantially arc shape or a substantially V shape by blowing from the dividing start point P3 and looks as if it is a line. Therefore, this film separation line is defined as a dividing line FL. Of course, the vicinity of the edge of the dividing line FL gradually approaches the both side walls 22 by blowing or liquid flow while gradually dissolving and spreading. Therefore, in FIG. 4, the dividing line FL is drawn with a clear solid line in the vicinity of the dividing start point P 3, but is drawn with a broken line at the side wall 22 part away from the dividing line FL.

Incidentally, in this embodiment, it seems that there is no acting member that brings the liquid level residual film F ′ after the division into the side walls 22 at first glance, but the blower 73 as the dividing means 71 has the liquid level residual after the division. The film F ′ is also brought into the side wall 22. Of course, the liquid flow formed in the transfer tank 2 also compensates for this effect.
Further, in this embodiment, the blower 73 as the dividing means 71 is provided on one side wall 22 and the liquid level residual film F ′ is divided into two, so that the dividing ratio to the side walls 22 is about 8: 2 as an example. The ratio is about 7: 3. Of course, in order to divide the liquid level residual film F ′, it is possible to divide the left and right side walls 22 almost equally. In this case, a dividing means 71 (blower 73) is installed at the center of the width of the transfer tank 2. This is generally considered to be performed, and it is necessary to consider the installation mode with the transferred object conveyance device 5 located in the center of the width of the transfer tank 2.

Note that the blower 73 as the dividing means 71 is not necessarily limited to one, and two or more blowers can be used in combination. As described above, the airflow of the blower 73 is forcibly increased (strongly). ) It can be said that it is a measure for not being able to. Specifically, for example, as shown in FIG. 1, a further small auxiliary blower 73a is installed on the side wall 22 provided with the blower 73, and is surely pushed into the direction of collecting a large amount of the liquid level residual film F ′. Is.
Of course, the air blowing direction of the auxiliary blower 73a is not necessarily limited to the mode of FIG. 1. For example, as shown in FIG. 6, the air blowing direction of the auxiliary air blower 73 a is substantially aligned with the air blowing direction of the main blower 73. It is also possible to set. Incidentally, in the embodiment of FIG. 6, the liquid level residual film F ′ is eventually divided into three parts and collected at three locations. Therefore, in this example, the liquid level residual film F ′ is not necessarily divided. It can also be said that it is not limited to two divisions (not limited to collection in two places). That is, various division forms and collection forms can be adopted depending on the properties of the transfer film F, the state of division / collection, and the like.
Further, for example, FIG. 7 shows an embodiment in which three fans (the main fan is 73 and the auxiliary fans are 73a and 73b) are provided as the dividing means 71, because the air volume of the auxiliary fan 73a is weak (largely). This is the idea of finally pushing one of the divided liquid level residual films F ′ laterally with another auxiliary blower 73b.
Note that the above-described method of dividing the liquid level residual film F ′ by blowing can cut the liquid level residual film F ′ in a non-contact state (the fan 73 itself can be divided without directly touching the film), and the transfer position can be transferred. The film F is effective in that it does not easily exert an adverse effect such as deformation on the film F.

Next, the discharging means 72 in the liquid level residual film recovery mechanism 7 will be described. The discharge means 72 collects the liquid level residual film F ′ pushed to the side wall 22 of the transfer tank 2 and discharges it to the outside of the transfer tank 2. In this embodiment, the discharge means 72 is provided inside the left and right side walls 22 of the processing tank 21. Apply the overflow tank 75. Here, in the overflow tank 75, a recovery port for introducing the liquid level residual film F ′ together with the transfer liquid L is referred to as a discharge port 76.
Further, since the discharge structure due to such overflow is adopted, the film holding mechanism 6 (here, the conveyor 61 using the belt 63) is released from the film holding mechanism 6 at the discharge port 76 as described above. This makes it easy to discharge (collect) the liquid level residual film F ′ pushed to the both side walls 22. In other words, if the belt 63 is present at the discharge port 76 of the overflow tank 75, the belt 63 closes the discharge port 76 and acts as if the discharge of the liquid level residual film F ′ is obstructed. Then, the film holding action is canceled at the discharge port 76 portion.

The release method of the film holding mechanism 6 at the discharge port 76 will be described in detail. In this embodiment, for example, as shown in FIG. It is provided in the vicinity of P3, and the conveyor 61 (belt 63) is folded back here. With such an arrangement mode, the film holding action by the film holding mechanism 6 (conveyor 61) is canceled at the discharge port 76 portion of the overflow tank 75.
However, it is preferable that the conveyor 61 is provided so as to be somewhat overlapped with the overflow tank 75 (the discharge port 76 portion) when viewed from the side, that is, the terminal pulley 62B is somewhat overlapped with the overflow tank 75 when viewed from the side. This will be described later (see FIG. 9A).
Even when the chain conveyor 67 is applied as the film holding mechanism 6 (see FIG. 28), the film holding action by the chain conveyor 67 can be canceled at the discharge port 76 portion by the same method as described above. In particular, when the chain conveyor 67 is applied, other methods than the above can also be adopted. That is, in this case, since the center of the upper chain 68 is usually set to match the liquid level in a side view state, for example, in the vicinity of the discharge port 76 as shown in FIG. The chain conveyor 67 (chain 68) can be entirely submerged below the liquid level to release the film holding action at the liquid level in the discharge port 76. Of course, as shown in FIG. 8 (b), the opposite of this structure, that is, the liquid level portion at the discharge port 76, the chain conveyor 67 (chain 68) is lifted above the liquid level to release the film holding action. It is also possible. Here, reference numeral 69A in the drawing is a guide body that regulates the chain conveyor 67 upward or downward so that the chain 68 does not block the discharge opening 76 in the vicinity of the discharge port 76. Further, reference numeral 69B in the drawing indicates the chain conveyor 67. Is a guide body that guides the vehicle at a normal height (orbit).

Further, in the overflow tank 75 of the present embodiment, as shown in FIG. 4, for example, a weir plate 78 as a blocking means 77 for blocking liquid recovery is provided in the middle of the discharge port 76. This overflow tank 75 is also intended to collect the liquid level residual film F ′ in two stages before and after the blocking means 77 (dam plate 78). In addition, the blocking means 77 performs control to weaken the flow velocity after releasing the film holding action in order to narrow the flow velocity induction range of the discharge port 76, thereby reliably transferring the liquid level residual film F '. Recovery is performed without adversely affecting the position (immersion area P1).
Incidentally, when the liquid level residual film F ′ is introduced into the overflow tank 75 from the entire area of the discharge port 76 without providing the blocking means 77 at the discharge port 76, the liquid level residual film F approaching the side wall 22. It has been confirmed by the present applicant that ′ is pulled as a whole, and reaches the transfer position and adversely affects the transfer film F at the transfer position, such as deformation.
Further, the transfer liquid L collected in the overflow tank 75 contains a lot of residual liquid film F ′, that is, a transfer pattern (ink component), a semi-dissolved water-soluble film, etc. Although it is preferable to dispose, these contaminants can be removed by a purifier and then recycled.
In addition, the overflow tank 75 is secured to the side wall 22 (frame) of the transfer tank 2 by a bolt or the like in the front-rear direction, which is the liquid flow direction, and the overall height of the overflow tank 75 can be changed. It is preferable to attach so that the inclination of the front-back direction of itself can be adjusted. Further, like the blower 73, it is preferable that the entire overflow tank 75 can freely move back and forth in the longitudinal direction of the transfer tank 2 in consideration of the change of the transfer position. Further, it is preferable that the blocking unit 77 can be appropriately changed in the installation position with respect to the discharge port 76 and can also change the width (length in the front-rear direction) as appropriate.

Here, the reason why the film holding mechanism 6 (conveyor 61) is somewhat overlapped with the overflow tank 75 (the discharge port 76 portion) in a side view will be described with reference to FIG.
First, FIG. 9B shows a case where the conveyor 61 does not overlap with the overflow tank 75, and at this time, the terminal pulley 62 B of the conveyor 61 is located upstream of the overflow tank 75. In this case, the both sides of the liquid level residual film F ′ held by the belt 63 (outward belt 63G) tend to be gradually released from the film holding (contact) by the falling liquid force at a high flow rate in the overflow tank 75 ( Originally, the portion held by the belt 63 tends to be separated from the belt 63). Therefore, in this case, as shown in the drawing, both side end portions of the liquid level residual film F ′ are first pulled by the overflow liquid, and the holding is released. This causes the pattern bending of the entire film to go upstream. Can trigger. Naturally, the influence of such pattern bending leads to pattern distortion of the transfer film F in the immersion area P1.
On the other hand, as shown in FIG. 9A, when the conveyor 61 is somewhat overlapped with the overflow tank 75, the liquid level residual film F ′ reaches the overflow tank 75 (discharge port 76). The film 61 can be held by the conveyor 61 (outward belt 63G). Therefore, the liquid level residual film F ′ is securely held by the conveyor 61 until the liquid level residual film F ′ reaches the discharge port 76, and is introduced into the overflow tank 75 (the front side of the blocking means 77). F 'falls as if it goes around the end pulley 62B, and is reliably recovered without adversely affecting the transfer position.

Here, for example, in the embodiment of FIG. 4 described above, the weir plate 78 is applied as the blocking means 77, but other forms may be adopted as the blocking means 77, for example, as shown in FIG. A form is also possible and preferable (this is referred to as a housing-type shield 79).
10 is a side groove-shaped member having a U-shaped cross section as an example, but this is not used as a container (groove) for receiving the recovered liquid. As shown in (b), it is stored (dropped) in the overflow tank 75 so that the opening part (open part) of the U-shaped cross section faces downward, and the overflow tank at the central plane part of the U-shaped cross section. The upper opening side of 75 is partially closed. Therefore, the accommodating shield 79 is installed in a bridge shape in the overflow tank 75, and in this installed state, a planar portion located on the upper part of the accommodating shield 79 (the portion that closes the overflow tank 75). ) Is responsible for the action of the weir like the dam plate 78, and for this reason, the plane portion is referred to as a dam action part 79a. Moreover, the part which is oppositely provided on both sides of the weir action part 79a is a leg part 79b. By housing both the leg parts 79b in the overflow tank 75, the accommodating shield 79 can only move in the front-rear direction. Is acceptable.

The merit of forming the storage type shield 79 in such a U shape is that the storage type shield 79 (blocking means 77) can be fixed simply by dropping this into the overflow tank 75, Further, by moving this in the front-rear direction (sliding in the longitudinal direction of the transfer tank 2), the front-rear two-stage discharge position and its discharge balance can be easily adjusted and changed.
In this respect, since the above-described dam plate 78 is normally installed at the discharge port 76 of the overflow tank 75, a fixing means for attaching the dam plate 78 to the overflow tank 75 (discharge port 76) is required separately. In addition, the adjustment described above involves attachment and detachment. However, if the housing type shield 79 is used, such a fixing means is not particularly required, and the adjustment can be performed very easily.

Here, since the housing-type shield 79 blocks liquid recovery by the overflow tank 75 as described above, the weir action portion 79a (top surface) is provided with the overflow tank 75 as shown in FIG. Is set higher than the discharge port 76 (for example, about 1 mm to 3 mm). In addition, as shown in FIG. 10C, the weir action portion 79a is set slightly lower than the transfer liquid surface (as an example, about 2 to 3 mm), which is a normal discharge amount setting. Sometimes the containment shield 79 is slightly submerged in the liquid. However, even in such a state, there is a difference in the speed of liquid recovery between the discharge port 76 portion where the accommodating shield 79 (weir action portion 79a) is not installed and the weir action portion 79a (weir action portion 79a portion). It will fully function as a weir.
Furthermore, by slightly submerging the weir action part 79a, it is difficult for the film residue to be caught on the part, and even if the film residue is caught on the part and stopped (climbing up and stopped), it can be recovered and transferred. The transfer liquid L in the tank 2 is not soiled.
In this respect, the dam plate 78 described above has a general damming structure, and since the dam plate 78 protrudes above the transfer liquid surface, it is conceivable that film residue is caught on the dam plate 78. In the meantime, this eventually becomes shattered and falls into the transfer tank 2, which may contaminate the transfer liquid L.

In collecting the liquid level residual film F ′ at the side wall 22 portion of the transfer tank 2, it is not always necessary to have one place on each side (one on each of the left and right side walls 22). As shown in FIG. 11, two portions on one side may be provided. Incidentally, in the embodiment of FIG. 11, the blower 73 as the dividing means 71 is difficult to set a large air volume, and therefore, when there is no ability to push the liquid level residual film F ′ to the outside of the conveyor 61, This is an embodiment in which an auxiliary overflow tank 75a (discharge means 72) is provided. However, in this case, since the auxiliary overflow tank 75a is provided in a protruding manner in the center of the transfer tank 2 (on the transport path of the transfer target W), the overflow tank 75a transports the transfer target W. It is necessary to consider not to disturb. Further, even if the liquid level residual film F ′ is divided into two in this way, the subsequent recovery may be performed at four locations (two locations on one side), and the number of divisions of the liquid level residual film F ′ by the dividing means 71 is not necessarily performed. And the number of collection points do not always match.
Further, the liquid level residual film recovery mechanism 7 (discharge unit 72) is not necessarily limited to the overflow structure, and other recovery methods can be adopted. For example, the transfer liquid L near the liquid level is divided. A vacuum technique of sucking together with the liquid level residual film F ′. That is, in this case, a suction nozzle is applied as the discharge means 72.

Further, in this embodiment, the liquid level residual film recovery mechanism 7 is further provided with a liquid discharge area purification mechanism 8, which will be described below. The liquid discharge area purification mechanism 8 is a mechanism that removes contaminants and bubbles A in the transfer liquid and on the liquid surface mainly on the decoration-unnecessary surface S2 side (the back side of the design surface S1) in the liquid discharge area P2. Specifically, for example, a film residue (relatively fine thing such as string waste in which a water-soluble film and ink are mixed) generated because the transferred object W is immersed so as to break through the transfer film F, The surplus film released from the liquid after adhering to the jig J or the transferred object W during immersion and once submerged below the liquid surface, the decoration of the transferred object W when the transferred object W (jig J) is discharged. Examples thereof include bubbles A and film residue generated in large quantities on the liquid surface on the unnecessary surface S2.
Then, by this mechanism, while the transfer target W is still present in the transfer liquid L, these contaminants and bubbles A are continuously moved away from the liquid discharge area P2, and the liquid discharge area P2 is purified at the same time. Thus, the wraparound to the design surface S1 side of the transfer target W is prevented as much as possible.

As shown in FIGS. 1, 2, and 4, the liquid discharge area purification mechanism 8 is provided with overflow tanks 82 as discharge means 81 on both the left and right sides of the liquid discharge area P 2. It is provided so as to overlap with the liquid discharge area P2. More specifically, a discharge means 81 (overflow tank 82) is provided inside the left and right side walls 22 of the liquid discharge area P2 in the transfer tank 2, and the liquid flow from the liquid output area P2 toward the overflow tank 82 (this is separated from the side). A flow LS) is generated mainly in the vicinity of the liquid surface, placed on the side separation flow LS, and foreign matters such as film residue and bubbles A are collected in the overflow tank 82 and discharged out of the tank. For this reason, in the state seen from the plane, as shown in FIGS. 1 and 2, an overflow tank 75 for collecting the liquid level residual film and an overflow tank 82 for purifying the liquid discharge area are provided in series. . Here, in the overflow tank 82, a collection port for introducing impurities such as film residue together with the transfer liquid L is referred to as a discharge port 83.

Further, as shown in FIG. 4 as an example, the overflow tank 82 for purifying the liquid discharge area is formed with a flange for guiding the recovered liquid at the discharge port 83. In particular, in this embodiment, the discharge port 83 is provided. The overhanging length from the surface to the processing tank 21 is formed to be relatively long, and this is a structure for increasing the flow rate of the transfer liquid L guided to the overflow tank 82 (for this reason, the flange is referred to as a flow rate enhancement flange 84). .
Since the transfer liquid L collected in the overflow tank 82 has a relatively low contamination mixing ratio, it is preferable to remove the contaminants by a purification device such as a precipitation tank or filtering and then use them for circulation (see FIG. 2).

In addition, since the liquid discharge area purification mechanism 8 is also for recovering foreign matter and bubbles A on the liquid surface of the liquid discharge area P2 (decoration unnecessary surface S2 side) as described above, in order to recover more reliably, It is preferable that air is blown over the liquid discharge area P2 and the foreign substances and bubbles A are pushed more positively into the overflow tank 82 (flow velocity enhancing brim 84). That is, in this embodiment, as shown in FIGS. 1, 2, and 4, for example, a blower 85 is provided on one side wall 22 of the transfer tank 2 (above the overflow tank 82). Contaminants such as bubbles A and film residue generated on the liquid surface in the area P2 (decoration unnecessary surface S2 side) are sent to the overflow tank 82 on the opposite side to the installation location and collected.
In this manner, the liquid discharge area P2 has the synergistic effect because the bubbles A and the contaminants are continuously removed by the blower 85 on the liquid surface, and the contaminants in the liquid are also collected by the overflow tank 82. As a result, high cleanliness can be achieved, and at the same time, even the wraparound of foreign matters to the design surface S1 side of the transfer target W can be prevented.

Furthermore, in consideration of the blower 73 for dividing the liquid level residual film F ′ by providing the blower 85 that acts on the liquid level in the liquid discharge area P2 as described above, a total of a plurality of units are provided in this apparatus. A blower will be installed. However, depending on various transfer conditions, for example, the shape of the transfer target W and the mode of the transfer target transporting device 5, the bubble A on the liquid level P2 is continuously blown by blowing the liquid level residual film F ′. It is also conceivable that the dust can be sent to the overflow tank 82. In that case, the blower 73 for dividing the film can also be used as the blower 85 for purifying the liquid discharge area, and these can be combined into one blower. It is also possible to do this.
The discharge means 81 of the liquid discharge area purification mechanism 8 is not necessarily limited to the overflow structure described above, and other discharge methods may be employed. For example, the transfer liquid L in which impurities are mixed is mainly used near the liquid surface. The vacuum method to inhale is mentioned. That is, in this case, a suction nozzle is applied as the discharge means 81.

Next, the design surface purification mechanism 9 will be described, but before that, the bubbles A generated on the design surface S1 side of the liquid discharge area P2 will be described. For example, when the transfer target W (jig J) is pulled up obliquely upward from the liquid level one after another, in the liquid discharge area P2, the transfer target W is already lifted above the transfer target W in the liquid discharge. The transferred object W or jig J may be positioned (this is referred to as the transferred object W or jig J pulled up in advance). At that time, the transfer liquid L may be drowned from the transfer target W or jig J pulled up in advance and dripped onto the liquid surface of the transfer tank 2, and the dropped wrinkle jumps on the liquid surface, for example. Bubbles A may be adhered to the design surface S1 of the transfer target W in the discharged liquid. Thereafter, when the transferred object W is irradiated with ultraviolet rays or the like in this state, the portion where the bubbles A adhere is transferred due to the stress of the bubbles A or the refraction of the ultraviolet rays as shown in FIG. Pattern distortion of the pattern (decorative layer) or defect that the pattern falls off (so-called pinhole). Accordingly, in the present embodiment, the design surface S1 of the transfer target W floating from the transfer liquid L in the liquid discharge area P2 is purified (mainly by the action of new water described later), on the liquid surface on the design surface S1 side. A design surface purification mechanism 9 is provided for the purpose of removing the generated bubbles A and removing impurities in the transfer liquid and on the liquid surface.

Hereinafter, the design surface purification mechanism 9 will be further described. The design surface purification mechanism 9 forms a liquid flow downstream from the design surface S1 of the transferred body W during liquid discharge or a liquid flow away from the design surface S1 (this is referred to as a design surface separation flow LR). As described above, the purpose is to prevent the foreign matter dispersed and staying in the transfer liquid L as much as possible from approaching (not adhering to) the design surface S1, and falling from the transfer target W pulled up in advance. For example, the bubbles A and impurities on the liquid surface generated by the soot may be discharged away from the design surface S1 and out of the tank. For this reason, the design surface separation flow LR is preferably formed by applying clean water that does not contain contaminants, or purified water from which contaminants have been removed from the recovered liquid (collectively referred to as new water). .

For this reason, the design surface purification mechanism 9 is configured so that the overflow tank 92 as the separation flow forming means 91 is discharged from the liquid receiving area W2 in the liquid discharge area P2, as shown in FIG. It is provided on the design surface S1 side. More specifically, in this embodiment, since the transfer target W floats in a state where the design surface S1 is inclined downward in the liquid discharge area P2, the transfer target W faces the design surface S1 of the transfer target W ( An overflow tank 92 is provided so as to oppose, and a design surface separation flow LR directed from the lower side to the upper side and further toward the overflow tank 92 in the liquid to be transferred (design surface S1) is formed. Here, in the overflow tank 92, a recovery port that mainly introduces fresh water together with the transfer liquid L is referred to as a discharge port 93.
Since the design surface separation flow LR is preferably formed by supplying fresh water as described above, for example, in FIG. 2, a new water supply port 97 is provided below the overflow tank 92 for design surface separation flow formation, From here, fresh water is supplied upward toward the liquid discharge area P2 (this new water is referred to as PU), and a design surface separation flow LR is generated using this. Of course, the fresh water PU supplied upward toward the liquid discharge area P2 is not only used for the generation and formation of the design surface separation flow LR, but also the side separation flow LS of the liquid discharge area purification mechanism 8 described above. It can also be used for generation and formation of.

In addition, there is also fresh water PD that is supplied downward from the new water supply port 97 toward the liquid discharge area P2, which facilitates the formation of a suction flow LV by a siphon type discharge unit 98 described later.
In addition, there is also fresh water PP supplied from the new water supply port 97 substantially parallel (horizontal) to the liquid discharge area P2 (in FIG. 2, the flow is directed toward the upstream side). It is discharged (supplied) at a lower speed than the fresh water PU and the fresh water PD from the vicinity of the middle layer between the water PD. Here, the “middle layer (near)” classifies the transfer liquid L in the transfer tank 2 into three types of upper layer (near the liquid surface) / middle layer / lower layer (near the bottom) depending on the depth (height) in the liquid. In this case, it is a middle layer, and this is likely to contain film residue.

The siphon type discharge unit 98 is provided on the back side of the new water supply port 97, and transfers the transfer liquid L (mainly middle layer water) containing impurities such as film residue from below the transfer tank 2 (treatment tank 21). Sucking (collecting) and discharging out of the tank. That is, the siphon type discharge unit 98 of the present embodiment is provided in the middle so that the lower suction port 98a is provided at a position lower than the fresh water supply port 97, and the transfer liquid L taken in from here can be sucked up to the liquid level. The transfer path is formed to be extremely narrow (for example, an interval of about 10 mm in the cross section of the flow path), and this path is a siphon path 98b. Further, the flow in the transfer liquid L sucked by the siphon type discharge unit 98 is referred to as a suction flow LV, and this suction flow LV is supplied downward from the fresh water supply port 97 toward the liquid discharge area P2. It is formed using new water PD (it is formed effectively by new water PD).

In order to make it easier to form the suction flow LV from the fresh water PD (to more efficiently form the suction flow LV from the new water PD), as shown in FIG. It is preferable to provide the tapered inclined plate 23 and to form the suction port 98a of the siphon type discharge portion 98 so as to face the uppermost end portion of the inclined plate 23. That is, the transfer tank 2 (processing tank 21) is formed by the inclined plate 23 such that the tank depth gradually decreases toward the tank end (formed so that the tank bottom gradually rises). It is desirable to provide the suction port 98a of the siphon type discharge portion 98 so as to face the uppermost end portion of the plate 23. As a result, the flow of the transfer liquid L rising along the inclination of the inclined plate 23 can be efficiently taken into the suction port 98a while maintaining its momentum.
Further, the purpose of forming the suction flow LV by the siphon type discharge unit 98 (or the inclined plate 23 in addition to this) is to make the contaminants such as film residue staying in the transfer liquid L (especially middle layer water) downward (bottom). This is to prevent the contaminants from being raised to the upper liquid discharge area P2 by sucking (recovering) this from after being transported so as to flow (after flowing). Accordingly, even if the transfer liquid L cannot be sucked up by the siphon-type discharge unit 98, the fresh water PD becomes a suction flow LV, and a flow (downward flow) toward the suction port 98a can be formed. A stream that promotes the separation of the precipitate can be formed.

Further, the fresh water PP supplied from the fresh water supply port 97 substantially parallel (horizontally) to the liquid discharge area P2 prevents the actions of the respective fresh water PUs and PDs from being inhibited from each other. It promotes the action of water PU / PD. Specifically, the fresh water PP promotes the action of discharging the middle layer water containing impurities on the suction flow LV formed from the fresh water PD, and the fresh water PU is designed to separate the design surface separation flow LR. It is also promoted that it is guided to the

overflow tanks

82 and 92 as a side separation flow LS, contributing to the expansion of the clean zone.

Here, it will be described that if the design surface purification mechanism 9 is not provided, impurities easily adhere to the design surface S1. For example, when a liquid flow is formed in the vicinity of the liquid surface of the transfer tank 2, the transfer target W that is pulled up from the transfer liquid L usually leaks the transfer liquid L from the upstream to the downstream. It emerges in a coughing state. At this time, the damped transfer liquid L flows so as to wrap around the lower side or the side of the transfer target W, and becomes a flow toward the design surface S1 facing the downstream side (flow wrapping around).
Further, when pulling up the transfer target W from the liquid, the force flowing from the vicinity of the transfer target W toward the transfer target W due to the difference between the pulling speed of the transfer target W and the remaining liquid level. Will work.
For this reason, a flow that naturally flows around the design surface S1 (flow toward the design surface S1) is formed with respect to the transfer target W in the discharged liquid. Contaminants that are dispersed and stay in the surface may be attracted to and adhered to the design surface S1. For this reason, in this embodiment, the flow of the transfer liquid L toward the design surface S1 is canceled or suppressed as much as possible by the design surface separation flow LR by the design surface purification mechanism 9.

Also, in the overflow tank 92 for forming the design surface separation flow, as shown in FIG. 4 and FIG. 12B, as an example, a flow velocity enhancing brim 94 is formed at the discharge port 93, which is overflow. This is because the flow rate of the transfer liquid L introduced into the tank 92 is increased.
Note that the separation flow forming means 91 in the design surface purification mechanism 9 is not necessarily limited to the overflow structure, and other discharge methods may be employed. For example, as shown in FIG. There is a vacuum method in which the transfer liquid L and fresh water are sucked mainly near the liquid surface. That is, in this case, the suction nozzle 95 is applied as the separation flow forming means 91.

In the present invention, the main feature is that the transfer target W is pulled up from the transfer liquid L while the liquid discharge position PO on the design surface S1 is maintained substantially constant. Here, the “liquid discharge position PO” refers to a liquid discharge point (liquid discharge point) on the design surface S1 of the transfer target W floating from the liquid, and is different from the liquid discharge area P2. Incidentally, the “liquid discharge area P2” refers to a range from the start of liquid discharge to the end of liquid discharge, and is a term (phrase) compared with the immersion area P1. .
Hereinafter, a pulling method (pulling method) for maintaining the liquid discharge position PO at a substantially constant position will be described. First, when a liquid flow is not formed near the liquid surface of the transfer tank 2 (hereinafter, this may be abbreviated as “liquid flow pear”), for example, as shown in FIG. When the design surface S1 of the body W is kept at a substantially constant inclination angle (this is the liquid discharge angle β with respect to the liquid surface, which is 34 degrees in this case) while being pulled up along the design surface S1, the liquid discharge position is constant. Thus, such a pulling method is referred to as “raising along the design surface” / “pulling up along the design surface”. That is, in the case of the transfer pear 2 with a liquid flow, the liquid discharge position PO on the design surface S1 is the same line when (i), (ii), and (iii) in FIG. It can be seen that the liquid discharge position PO is kept constant because it is lined up (becomes the same position with respect to the transfer tank 2).

On the other hand, in the method of pulling up shown in FIG. 13B, a liquid flow (horizontal transfer direction) is formed near the liquid surface of the transfer tank 2 (hereinafter, this is abbreviated as “liquid flow ant”). 3) shows a case where the transfer target W is lifted obliquely along the design surface S1 at a constant liquid discharge angle β (for example, 34 degrees) (pickup along the design surface). In this case, when (i), (ii), and (iii) in FIG. 13B are viewed in the vertical direction, the liquid discharge positions “I”, “B”, and “C” in each stage are the same. At first glance, it seems that the liquid discharge position is the same because it is lined up on the line. However, in the case of FIG. 13B, since the liquid flow is formed, it is considered that the transfer liquid L always moves in the horizontal direction near the liquid surface. Therefore, for example, the liquid discharge position “I” in (i) of FIG. 13B is slightly moved downstream in the horizontal direction (advancing direction of the transfer target W) in (ii) of FIG. 13B. For example, the position is “i ′” in the figure and deviates from the actual liquid discharge position “b”. Note that the position “I” shown in (iii) of FIG. 13B indicates that the position “I ′” is further shifted to the downstream side in the horizontal direction (moved position).

For this reason, in the case of a liquid flow ant, as shown in FIG. 13 (c), a transfer component in the same speed and in the same direction as the liquid flow is added to the above-mentioned "pull up along the design surface" The liquid discharge position PO can be kept constant by pulling up the transfer target W at the liquid discharge angle β (vector synthesized). In addition, such a pulling method is “picking up with a liquid flow” / “pulling up with a liquid flow”, and the liquid discharge angle is more than the angle of “pickup along the design surface”. The tilt angle approaches the liquid level, and the liquid discharge angle β is small. The liquid discharge angle β in the present specification indicates an angle formed between the liquid surface and the design surface S1, and in particular, the liquid surface here refers to the traveling direction (liquid flow direction) of the transfer target W. pointing.
As described above, “liquid discharge position (almost) constant” in the present invention means that the liquid discharge position PO is maintained constant by pulling up the transfer target W along the design surface in the case of liquid flow. In the case of a liquid flow ant, the liquid discharge position PO is kept constant by pulling up (combining) the horizontal transfer component of the flow rate.
As described above, it is possible to pull up the transfer target W while maintaining the liquid discharge position PO regardless of the ant pear of the liquid flow. Although not noted, when the transfer target W is pulled up along the design surface S 1, it basically means that no liquid flow is formed in the transfer tank 2.

Moreover, since the preferable installation aspect of the overflow tank 92 (for design surface separation flow formation) differs with the ant pear of a liquid flow, this is demonstrated below.
With respect to the overflow tank 92, it is preferable to keep a constant distance from the liquid discharge position PO to the overflow tank 92 (discharge port 93) from the start to the end of liquid discharge of the transfer target W (as an example, about 10 to 200 mm). This is because the design surface separation flow LR is reliably and uniformly applied to the design surface S1 of the transfer target W.
For this reason, in the case of no liquid flow (that is, when the transfer target W is pulled up along the design surface), for example, as shown in FIG. 14A, the overflow tank 92 is also maintained at a substantially constant position (fixed). By doing so, the separation distance D between the liquid discharge position PO and the overflow tank 92 can be kept constant.
On the other hand, in the case of a liquid flow ant (that is, when the liquid flow is taken into consideration), the transfer target W is lifted while adding the horizontal transfer component of the liquid flow. For example, as shown in FIG. The overflow tank 92 is also moved at the same speed and in the same direction as the liquid flow during the discharge of the transfer target W, so that the separation distance D between the discharge position PO and the overflow tank 92 can be kept constant.

Next, when the transfer target W (design surface S1) is bent into a “he” shape as shown in FIG. 15, for example, the same applies to the case where it is bent into a “ku” shape. ) And a pulling method (preferably pulling method) for maintaining the liquid discharge position PO substantially constant will be described. Here, the short piece portion of the transfer target W is WS, the long piece portion is WL, and the bending point is WP. Further, as a method of pulling up the transfer target W, it is assumed that liquid is started to be discharged from the short piece portion WS, and then the bending point WP and the long piece portion WL are sequentially discharged. Furthermore, the design surface S1 is assumed to be the inside (small-angle side) of the “he” shape.
In the following description, an undesired pulling method, that is, the liquid discharge position PO can be maintained substantially constant in such a transfer target W based on FIG. 15A. . Incidentally, in FIG. 15A, it is assumed that both the short piece portion WS and the long piece portion WL are pulled up at the same liquid discharge angle β (34 degrees in this case).
For example, (i) and (ii) in FIG. 15 (a) pull the transfer object W obliquely at a constant angle (liquid discharge angle β) of 34 degrees, for example, along the inclination (design surface S1) of the short piece portion WS. It is a state (lifting along the design surface). At that time, as shown in (ii) of FIG. 15 (a), when the bending point WP reaches the liquid level, the pulling-up (lifting operation) of the transfer target W is temporarily interrupted, and this time FIG. As shown in (ii) and (iii) of), the transferred object W is rotated around the bending point WP, and the long piece WL is at the liquid discharge angle β (34 degrees in this case). It is to be converted. In FIG. 15A, the short piece portion WS that has once floated is re-immersed during the rotation of the transfer target W (long piece portion WL). Thereafter, as shown in (iv), (v), and (vi) of FIG. 15A, the transfer target W is placed along the long piece portion WL (design surface S1) with the liquid discharge angle β (here, 34 degrees) at an angle (pick up along the design surface).

In the pulling method shown in FIG. 15 (a), a rotation operation at a bending point WP is entered midway. However, if the transfer target W is lifted along the design surface S1, the liquid discharge position PO is kept constant (fixed). However, the following inconvenience (defect) occurs.
First, it is not preferable to rotate the transfer target W (long piece WL) relatively large in the transfer liquid L around the bending point WP, which causes a ripple or stirring flow on the transfer liquid surface, As a result, it is conceivable that the transfer pattern having the surface protection function attached to the design surface S1 flows (sagging defect). Of course, the same portion of the transfer target W remaining in the transfer liquid L for a relatively long period of time due to the rotational operation as described above can also cause a sagging failure.
Further, it is not preferable that the short piece WS once discharged is re-immersed by the rotation operation of the transfer target W. In this case as well, the sagging defect and the scrap defect are liable to occur on the redesigned design surface S1. .

Next, a preferred method of pulling up the transfer target W bent in the shape of “he” (preferably pulling up while maintaining the liquid discharge position PO substantially constant) will be described with reference to FIG.
Here, first, as shown in FIG. 15B (i) as an example, a liquid discharge virtual line CV substantially along the design surface S1 is assumed. This is a line that smoothly connects the short piece portion WS and the long piece portion WL in order to avoid the rotation operation at the bending point WP as described above, and to avoid this (not necessarily a curve), The transfer target W is pulled up along the liquid discharge virtual line CV. That is, the transfer target W is pulled up so that the liquid discharge position in the liquid discharge virtual line CV is constant.
Note that the liquid discharge virtual line CV is set so that the liquid discharge angle β of the transfer target W is within a certain range (for example, 25 degrees to 55 degrees) when shifting from the short piece section WS to the long piece section WL. It is preferable to set, and in this way, the transfer target W can be moved at a constant speed and smoothly ascend from the liquid or smoothly move from immersion to liquid discharge. Is. Incidentally, the liquid discharge angle of the transfer target W is set to about 25 to 55 degrees because if the liquid discharge angle β is smaller than 25 degrees, the design surface S1 is easily affected by the surface tension, and the sagging defect is likely to occur. This is because, when the liquid discharge angle β is larger than 55 degrees, the trace of the liquid drop or the liquid flow that has passed down easily appears on the design surface S1 side.

A specific method of pulling up will be described. Here, as an example, as shown in FIG. 15B (i), the short piece portion WS is arranged along the portion with a substantially constant liquid discharge angle β (here, 34 degrees). At the time when the bend point WP passes through the liquid surface (at the time of liquid discharge) after starting to pull up diagonally (pulling along the design surface), as shown in (ii) of FIG. The liquid discharge angle β on the line CV (inclination of the tangent at the liquid discharge position on the line) is set to 54 degrees, for example, and the transfer target W is pulled up. That is, in the case of the present embodiment, between (i) and (ii) in FIG. 15B, the transferred object W is pulled up along the virtual liquid discharge line CV while gradually increasing the liquid discharge angle β. Is something to go.
Here, the position at which the liquid discharge angle β (tangent) is set may be set at a point where the liquid discharge virtual line CV intersects the liquid surface (in other words, the current liquid discharge position). In consideration of setting the liquid discharge angle β in order to determine the liquid discharge posture of the liquid, it is preferable to set it at the liquid discharge point that reaches the liquid surface immediately after that. This is the same not only when the transfer target W is pulled up along the liquid discharge virtual line CV but also when the transfer target W is pulled up along the design surface S1. For this reason, in this specification, the “liquid discharge position (liquid discharge point)” considering the liquid discharge angle β includes not only the current liquid discharge position but also the liquid discharge position immediately thereafter (immediately after the current time). It is a waste.
Incidentally, in this embodiment, since the transfer target W is pulled up along the liquid discharge virtual line CV, for example, as shown in (ii) and (iii) of FIG. At the point away from the design surface S1, particularly at the bending point WP here, there is inevitably a deviation between the liquid discharge position PO on the actual design surface S1 and the liquid discharge position on the liquid discharge virtual line CV. In view of the above, “(almost liquid discharge position)” and “substantially” are attached in the scope of claims. The same applies to “almost” when the distance between the liquid discharge position PO and the overflow tank 92 for forming the design surface separation flow is maintained substantially constant.

Thereafter, as shown in (iii) to (vi) of FIG. 15B, the transferred object W is pulled up along the virtual liquid discharge line CV while gradually decreasing (gradually decreasing) the liquid discharge angle β. For example, in the figure (iii), the liquid discharge angle β is 52 degrees, in the figure (iv) the liquid discharge angle β is 47 degrees, in the figure (v) the liquid output angle β is 45 degrees, and in the figure (vi) The liquid angle β is 34 degrees.
Note that the overall liquid discharge operation of the transfer target W in FIG. 15B is that the transfer target W gradually rotates so as to always move the rotation center to the liquid discharge rear end side. It is a form that rises. In other words, the liquid discharge virtual line CV and the liquid discharge angle β are set so as to take such a smooth liquid discharge operation.
In addition, it is preferable that the angle formed with the transfer liquid surface is within 25 to 55 degrees for the part that has already been discharged, for example, the short piece WS when the long piece WL is discharged.
Further, assuming the liquid discharge virtual line CV, the above-described method of pulling up along this line is not limited to the transfer target W having the bent portion WP as described above, but the transfer target W (design surface S1). This is a technique that can be applied to a case where the curvature greatly changes, a surface is discontinuous, or there is an opening Wa.

Next, a method for pulling up the transfer target W while maintaining the liquid discharge position PO substantially constant when the design surface S1 of the transfer target W is curved in a concave shape will be described.
First, the state in which the design surface S1 is curved in a concave shape means that, as shown in FIG. 16, for example, the design surface S1 facing the lower transfer liquid surface during transfer is formed in a concave shape with respect to the transfer liquid surface. Refers to what is being done. Even in such a transfer target W, if the transfer target W is pulled up along the design surface S1 (here, the transfer target W is pulled up along the arc-shaped locus of the design surface S1), the liquid discharge position PO is kept constant.
However, simply by pulling up the transfer target W along the design surface S1, as described above, the transfer target W may be re-immersed, and the transfer target W from immersion to liquid discharge It is also possible that the operation transition cannot be performed smoothly. Further, the liquid discharge angle β of the transfer target W is preferably 25 ° to 55 °, but the liquid discharge angle β of the transfer target W may not be within this range simply by pulling up along the design surface S1. Conceivable. Specifically, in the case of a liquid flow ant, it is preferable to move the transfer target W so as to always go downstream from immersion (transfer) to liquid discharge. However, by simply pulling up along the design surface S1, this liquid flow It is conceivable that the movement reversely moves (returning movement), and a large rotational movement in the transfer liquid L may be taken (leading to sagging defects and dregs defects). It should be noted that it is good to move the transfer target W smoothly without always returning it (in the direction of travel from the immersion side to the liquid discharge side), even when there is no liquid flow.

For this reason, in this embodiment, as shown in FIG. 16A as an example, the transfer target W is pulled up while maintaining the liquid discharge angle β at the liquid discharge position PO at approximately 34 degrees. is there. That is, in FIG. 16 (a), the liquid discharge angle β (design) at the liquid discharge position PO is basically based on pulling up the transfer target W along the design surface S1 so as to maintain the liquid discharge position PO substantially constant. By keeping the tangent line on the surface S1 substantially constant, the transfer target W is controlled to be discharged smoothly (so that a smooth liquid discharge operation is performed).
Of course, the liquid discharge angle β is not necessarily maintained constant, and may be changed within the range of 25 to 55 degrees as described above as long as the smooth liquid discharge operation of the transfer target W is not hindered. This may be determined by the shape of the design surface S1 or the like.

Further, as another method of pulling up when the design surface S1 of the transfer target W is curved in a concave shape, for example, as shown in FIG. 16B, a liquid discharge start portion and a liquid discharge end portion on the design surface S1. It is also conceivable that this is defined as a liquid discharge virtual line CV, and the transfer target W is pulled up at a constant liquid discharge angle β (for example, 34 degrees) along this line. Of course, such pulling up is inevitable at the liquid discharge position PO on the actual design surface S1 and the liquid discharge position on the liquid discharge virtual line CV as shown in (ii) of FIG. If the deviation is small and has no adverse effect (for example, if the stirring flow does not occur in the transfer liquid L, or if the stirring flow is generated, the adverse effect exerted by this is extremely small). ), A method of pulling that can be fully adopted.

Next, a method for pulling up the transfer body W while maintaining the liquid discharge position PO substantially when the design surface S1 of the transfer body W is curved in a convex shape will be described.
First, the state in which the design surface S1 is curved in a convex shape means that, for example, as shown in FIG. 17, the design surface S1 facing the lower transfer liquid surface during transfer is convex with respect to the transfer liquid surface. It refers to what is formed (so that it protrudes). Even in such a transfer target W, if the transfer target W is pulled up along the design surface S1 (here, the transfer target W is pulled up along the arcuate locus of the design surface S1), The position PO is kept constant. However, also here, it is conceivable that a drip defect or a deficiency defect occurs only by pulling up the transfer target W along the design surface S1.

For this reason, in this embodiment, as shown in FIG. 17 as an example, the transferred object W is pulled up while gradually decreasing the liquid discharge angle β at the liquid discharge position PO from 55 degrees to 25 degrees. .
Here, the reason why the liquid discharge angle β near the start of liquid discharge is set large in this embodiment is to smoothly carry a series of operations from immersion to liquid discharge, and the design surface S1 is affected by the surface tension. This is to make it difficult. That is, in the case of the present embodiment, for example, when the liquid discharge angle β near the liquid discharge start is extremely small, the liquid discharge start posture of the transfer target W is lying near the liquid surface, and the previous immersion operation is performed. It is difficult, and the transition from the immersion operation to the liquid discharge operation cannot be performed smoothly. Further, in the above posture, the design surface S1 is easily affected by the surface tension, and the sagging defect is likely to occur.
The reason why the liquid discharge angle β in the vicinity of the liquid discharge end is set small is to reduce the rising angle of the liquid discharge front end part already floating above the transfer liquid surface, thereby suppressing the occurrence of liquid dripping on the design surface S1. Because.

Next, a preferable situation when the transfer target W is pulled up from the transfer liquid L (at the start of liquid discharge) will be described. Incidentally, the above-described pulling-up method of the transfer target W is mainly related to the design surface S1, and can be said to be an intermediate operation during liquid discharge. On the other hand, the liquid discharge start time is an operation when the transfer target W comes out from the surface of the transfer liquid and starts to rise, and this will be described below.
The transfer target W usually has a thickness, and when the design surface S1 including the thickness portion is included, the design surface S1 is bent at the thickness portion. Even in this bent portion (thick portion of the design surface S1), it is conceivable that the liquid discharge virtual line CV as described above is assumed and the transfer target W is pulled up along this line. Since the dimension is extremely small compared to the width and size of the surface S1 (because it is thin), it is assumed that a liquid discharge virtual line CV is assumed at such a short dimension, and pulling up along this line is to be transferred. W is greatly rotated in the transfer liquid L, and there is a concern about sagging defects and defective chips. For this reason, in practice, such a method of raising is generally not performed even if a thick portion is included in the design surface S1. That is, at the beginning of the liquid discharge, it is assumed that the thick portion is not so much included in the design surface S1, and that the liquid discharge position PO is not particularly maintained at a fixed position. For example, FIG. As shown in (b), importance is attached to the fact that the transfer target W is discharged from one point in a side view state. This is for preventing the transfer target W from being parallel to the liquid surface at the time of the start of liquid discharge. For example, in the case of the transfer target W having the shape of “he” shown in FIG. If the liquid is discharged in a state where the short piece portion WS is parallel to the water surface, as shown in FIG. 26, the liquid surface of the short piece portion WS is rippled (negative pressure attack), and the short piece portion has already been generated. This is because the ink adhering to the WS may flow (sagging failure).
In addition, since the above-described method of pulling up is performed at the liquid discharge start portion (thick portion), the liquid discharge position PO is slightly shifted when the liquid discharge start portion or the intermediate operation is shifted from here. In the claims, “almost” of “almost constant (the position of liquid discharge)” also takes this into consideration.

Further, normally, the transfer target W is hydraulically transferred while being attached to the jig J, and the liquid discharge operation of the transfer target W is also accompanied by the jig J. For this reason, it is desirable to consider the lifting operation including the jig J in the actual hydraulic pressure transfer. Specifically, when the jig J is pulled up prior to the transfer target W, when the jig J is discharged, a wave due to the pulling up of the jig can occur on the transfer liquid surface. If the fixing position to the jig J can be changed, the position is set in consideration of the jig J.

Further, for example, as shown in FIG. 19, when a plurality of transferred objects W are attached to one jig J, it is difficult to pull up the individual transferred objects W along the design surface S1. It is. That is, when such a pulling method (how to pull along the design surface S1 of each transferred object W) is performed, the transferred object W becomes a complicated operation in the transfer liquid L, resulting in defective or sagging defects. When it is likely to occur or when there is a risk of re-immersion, as shown in FIG. 19, a straight line connecting the ends of the transfer target W is assumed as a liquid discharge virtual line CV, and along this line. A plurality of transferred objects W are pulled up. That is, even in such a case, the plurality of transfer bodies W are pulled up along the assumed liquid discharge virtual line CV instead of along the design surface S1 of each transfer target body W, and liquid discharge on this line is performed. The position is pulled up so as to maintain a certain position. Of course, the liquid discharge angle β at this time may be substantially constant (for example, 34 degrees), or may be raised while changing in the range of 25 degrees to 55 degrees.

Next, a method for purifying the transfer liquid L collected in the overflow tank 82 for forming the side separation flow, the overflow tank 92 for forming the design surface separation flow, and the siphon discharge unit 98 will be described. For example, as shown in FIG. 2, the transfer liquid L collected by these is sent to a purification device through a water level adjustment tank, and after impurities are removed, fresh water (purified water) is passed through a temperature control tank. Are reused. Of course, the foreign matter captured by the purification device is discarded.
In addition, a waste pipe for discharging contaminants (sludge) accumulated here is provided in the middle of the pipe for sending the transfer liquid L (including impurities) collected in the overflow tank 82 to the water level adjusting tank or at the bottom of the water level adjusting tank. To be connected. Further, the overflow tank 75 serving as the liquid level residual film recovery mechanism 7 is generally discarded as it is because of the high mixing ratio of impurities as described above.
In order to remove contaminants from the transfer liquid using a water level adjustment tank or purification device (precipitation tank), etc., the liquid in the adjustment tank or precipitation tank is temporarily stored with a plate (damage plate), etc. Purification can be achieved by sending a relatively clean supernatant to the subsequent stage.

Further, the fresh water purified as described above is supplied, for example, from below the guide conveyor 33 on the film supply side (upstream side) as shown in FIG. In addition, for example, it is supplied from the new water supply port 97 (below the overflow tank 92 for forming the design surface separation flow ) upward, downward, and parallel (horizontal) toward the liquid discharge area P2. Here, “new water PU supplied upward toward the liquid discharge area P2” is new water for forming the design surface separation flow LR and the side separation flow LS as described above. The “new water PD supplied downward” is the new water for forming the suction flow LV by the siphon discharge unit 98.
Further, a punching metal or the like is provided at the discharge port for supplying fresh water to the transfer tank 2, specifically, the inclined portion 24 in the middle of the transfer tank and the new water supply port 97, and the supplied fresh water It is preferable that the water is uniformly discharged from a relatively wide range (preventing the fresh water from partially going straight).

In the hydraulic transfer, as described above, various types and states of the transfer film F (transfer pattern) and the activator are applied, and the transfer target W having various sizes is processed, so that the immersion area P1 is used. For example, the liquid discharge area P2 may be moved back and forth by about 800 mm to 1200 mm. Therefore, the immersion area P1, the terminal pulley 62B of the film holding mechanism 6, the dividing means 71 (

blowers

73 and 73a) and the overflow tank 75 of the liquid level residual film recovery mechanism 7, the overflow tank 82 and the blower of the liquid discharge area purification mechanism 8 are used. 85, and the overflow tank 92 (separation flow forming means 91) of the design surface purification mechanism 9 are in a close positional relationship with each other. Therefore, it is preferable to move each of the above components simultaneously or independently with the movement of the immersion area P1. For this reason, in this embodiment, as shown in FIG. 2, for example, the end pulley 62B of the film holding mechanism 6 is used. The

blowers

73, 73a, and 85 and the

overflow tanks

75 and 82 are mounted on a gantry 29 that can move in the longitudinal direction of the transfer tank 2 (in the front-and-rear direction), and the basin that can independently move the overflow tank 92 back and forth. 30 is configured so that these can be appropriately moved in accordance with the movement of the immersion area P1 and the liquid discharge area P2.
Incidentally, the movement method of each

gantry

29 and 30 can be automatically controlled manually or using a linear motor or the like (actually, the positions of the

gantry

29 and 30 are adjusted according to the lifting program of the transfer target W). A program that runs automatically is realistic).

Further, in this embodiment, when the transfer film F is supplied to the transfer tank 2, an extension reduction preventing mechanism 10 that suppresses the extension reduction of the transfer film F is provided. This mechanism will be described below. The extension reduction prevention mechanism 10 prevents the active agent component K, which is liberated and exuded from the film surface on the transfer liquid surface upon adhering to the liquid surface, from staying on the liquid surface and stretching the film to inhibit the extension of the transfer film F. Thus, both sides of the transfer film F supplied onto the transfer liquid surface are reliably attached to the conveyor 61 (belt 63) provided in the vicinity of the side wall 22 of the transfer tank 2. In the following description, first, the reason (background) for inhibiting the extension of the transfer film F by the activator component K flowing out from the transferred transfer film F will be described.

In the transfer, an activator is applied to the transfer film F in order to activate the transfer pattern. A part of the activator applied to the film is transferred to the transfer film (contact with the transfer liquid L). It separates (releases) from the surface of F and flows out (exudes) on the surface of the transfer liquid (this is mainly referred to as the activator component K in this specification). The outflow of the activator component K onto the liquid surface is not necessarily limited to the supply direction (liquid flow direction) of the transfer film F, and may flow out in various directions. It is considered that the outflow (preceding) in the film supply direction is relatively large because the film is being supplied. In addition, for this reason, when the hydraulic transfer is repeated, the activator component K gradually increases on the transfer liquid surface and stays, for example, near the side wall 22 of the transfer tank 2 having a weak liquid flow. . The activator component K staying in the vicinity of the side wall 22 becomes highly concentrated on the liquid surface, and it becomes as if the oil component forms a film (oil film) on the water surface (this is referred to as a liquid film for convenience), which is a transfer film. It acts to refuse the extension (spreading) of F. That is, if the hydraulic transfer is continued, the liquid film formed by the activator component K hinders the extension (spreading) of the film.

In addition, there are other factors that hinder the extension of the transfer film F supplied onto the transfer liquid surface. For example, the transfer liquid L in the transfer tank 2 is used for environmental protection and effective use (recycling) of resources. Most of them are recycled. For this reason, the activator component K (liquid film) released on the transfer liquid surface does not simply accumulate (float) on the liquid surface but also partially dissolves in the transfer liquid L. Therefore, if the hydraulic transfer is repeated, the concentration of the activator in the transfer liquid L gradually increases, and the viscosity of the transfer liquid L increases, which also becomes a factor that hinders the extension of the transfer film F.
Further, although the activator of the ultraviolet curable resin is indoors, the activator component K is slightly cured by light, so that the viscosity of the transfer liquid L tends to be further increased. Further, as described above, since most of the transfer liquid L is reused and there is a social environment in which the amount of waste liquid is to be suppressed, this is a factor that further increases the viscosity of the transfer liquid L. However, since hydraulic transfer requires stable transfer at a high level, the surface of the transfer liquid is inevitably stabilized by suppressing ripples, and this is a transfer liquid of an activator (resin component). It is also a fact that it acts to prevent mixing into L.

Note that the phenomenon in which the extension of the transfer film F is hindered by the activator component K on the transfer liquid surface is an activator used for hydraulic transfer (hydraulic transfer that does not require a top coat) to form a transfer pattern having a surface protection function. This is conspicuous, and it is considered that the activator has a higher viscosity than ordinary solvent-based ones, and therefore tends to suppress the elongation of the transfer film F.
In addition, as shown in FIG. 28, the transfer film F supplied on the transfer liquid surface generally has a difference in elongation between the transfer pattern located on the upper side of the transfer liquid surface and the water-soluble film located on the lower side. (The water-soluble film has a higher elongation rate) and gradually curls upward. For this reason, the transfer film F supplied to the transfer tank 2 becomes more difficult to come into contact with the film holding mechanism 6 provided near the side wall 22.
For this reason, when there is no extension lowering prevention mechanism 10, if the hydraulic transfer is repeated, the transfer film F that has been initially extended to the conveyor 61 after landing is not attached. In this embodiment, this mechanism prevents such a decrease in extension.

Here, in this embodiment, a blow method is adopted as the extension reduction preventing mechanism 10 and spreads as a liquid film on the transfer liquid surface between the film holding mechanism 6 (conveyor 61) and the transfer film F, The activator component K that inhibits the extension of the transfer film F is removed by blowing air. That is, as shown in FIG. 1 as an example, the mechanism sends air to the vicinity of the side wall 22 where the flow of the transfer liquid L (liquid flow) is weakened and the activator component K is likely to stagnate, particularly to the left and right sides of the blower 26. It is preferable to push (send) the active agent component K located (floating) in the region between the film holding mechanism 6 and the side wall 22. Incidentally, since the upper edge of the belt 63 is set at a position higher than the transfer liquid surface between the film holding mechanism 6 and the side wall 22, it does not substantially affect the transfer position, or the transfer position. Therefore, in this embodiment, the activator component K is pushed to the site. In the present embodiment, as described above, since the blower 26 has an action of extending the transfer film F to the periphery, the extension lowering prevention mechanism 10 is here used to clearly distinguish the action from the blower 26. It is what.
In the present embodiment, as already described, the overflow tank 75 is provided along the both side walls 22 of the transfer tank 2 outside the conveyor 61 as the film holding mechanism 6. The activator component K sent between the two is recovered. Of course, in this case, for example, as shown in FIG. 4, a discharge port 76a for introducing and collecting the activator component K is also formed on the front edge side (upstream side) of the overflow tank 75.

Further, in the embodiment shown in FIG. 1, two compressed air blowing nozzles 102 are applied as the extension reduction preventing mechanism 10 (removing means 101). More specifically, since the transfer film F supplied to the transfer tank 2 inherently swells and softens including the transfer liquid L and gradually expands in all directions, in FIG. Air is blown from the nozzle 102 so as to act on the liquid surface facing the spreading edge of the transfer film F, so that the activator component K mainly floating near the edge is removed from the air, and the transfer film F is removed. It is intended to extend in both directions near the edge (to prevent reduction in extension). Here, the compressed air blowing nozzle 102 is preferably provided with an articulated joint type flexible hose as shown in the figure, because it is easy to finely adjust the position of the nozzle and the blowing direction.

Incidentally, it is preferable that the air blow for removing the activator component K does not act on the transfer film F but applies air only to the surface of the transfer liquid where no film is present. This is because the surface is stably held and the transfer film F is transferred to the transfer position (immersion area P1) with as little ripple as possible. Moreover, in that respect, for example, as shown in the enlarged view of FIG. 1, a nozzle formed in a tapered shape toward the discharge port is used, and the target liquid level (such as a liquid level facing the spreading edge of the film) is set. It is desirable to let air act at a pinpoint. On the other hand, for the

blowers

73 and 85 and the like, it is preferable to use a fan having a relatively wide discharge port.
Further, in FIG. 1, when air is blown, the upstream (front side) liquid surface on which the transfer film F extends by liquid landing, more specifically, upstream of the operation start end (start pulley 62 A) of the film holding mechanism 6. The air is blown so that air acts on the liquid surface on the side, and before the transfer film F tries to extend, the activator component K that becomes an obstruction factor is removed, thereby extending the transfer film F. This is to make it more effective. The activator component K floating on the transfer liquid surface by such air blowing is sent between the side wall 22 and the film holding mechanism 6 while bypassing the action start end (starting pulley 62A) of the film holding mechanism 6. It is.

In the embodiment shown in FIG. 1, the air is blown from the two compressed air blowing nozzles 102 slightly reverse to the transfer liquid flow. However, the two compressed air blowing nozzles 102 are arranged on the liquid surface. Therefore, there is no concern that the air flow by the compressed air blowing nozzle 102 hinders the liquid flow itself of the transfer liquid L because it is sufficient that the activator component K (liquid film) is driven to the side wall 22. Incidentally, in the case of air flow reverse to the transfer liquid flow, about 90 to 120 degrees with respect to the liquid flow direction (downstream direction) is preferable.
Of course, the air blowing by the compressed air blowing nozzle 102 can be performed in the downstream direction along the flow of the transfer liquid L as shown in FIG. However, even in this case, it is preferable to blow the activator component K on the transfer liquid surface so as to repel the both side walls 22. More specifically, the activator component K on the liquid surface floating in the vicinity of the side wall 22 on the film supply side is transferred from the front end 62A of the film holding mechanism 6 (conveyor 61) to the film holding mechanism 6 (conveyor 61). It is preferable to blow air so as to push between the side walls 22. Incidentally, in such a downstream blowing mode, about 50 to 90 degrees with respect to the liquid flow direction (downstream direction) is preferable.
As described above, the blowing as the extension reduction preventing mechanism 10 (removing means 101) is preferably the same as the blower 26 in that the air is not directly applied to the transfer film F and the blowing direction is wide. Are very different. In other words, the blower 26 directly applies air to the surface of the transfer film F, and the air blowing direction is set in one direction from upstream to downstream in consideration of film transfer. It is.

Next, a guideline for adjusting the amount of air flow when the compressed air blowing nozzle 102 blows air to prevent the reduction in extension will be described.
The present applicant conducted the following test in order to confirm the blowing effect of the extension reduction preventing mechanism 10. In this test, 4000 liters of the transfer liquid L (water) was put in the transfer tank 2 and circulated, and the continuous operation was performed while applying the conventional activator to the conventional hydraulic transfer film. The process is terminated when the mechanism 6 is no longer attached (separated) and the amount of the active agent used is confirmed. Here, in the first time (trial 1), the blowing was not performed to prevent the extension from being lowered, and the blowing was performed only in the second time (trial 2). As a result, in trial 1, after about 5 hours, when about 4 kg of the activator was used, the transfer film did not adhere to the film holding mechanism 6. Trial 2 was carried out under the same conditions except that the water in the transfer tank 2 was replaced and the extension reduction prevention mechanism 10 was blown as described above. In Trial 2, no change was observed. Since the transfer film always reached the film holding mechanism 6 stably, the confirmation (test) was completed after 10 hours of continuous operation (using about 8 kg of activator).

Judging from this test, it can be considered that trial 1 did not perform blowing for preventing the reduction in stretching, and therefore the stretching force of the transfer film F was gradually lost, causing a reduction in stretching and no longer adhering to the film holding mechanism 6. Also, in trial 2, since the blowing for preventing the decrease in stretch is always performed, the activator component K on the liquid surface is removed (concentration on the liquid surface is reduced), and the film stretch force has a stronger relationship. Therefore, it is considered that the extension of the transfer film F (arrival at the film holding mechanism 6) was always maintained.
Because of this, as a guideline for adjusting the air flow,
(The activator concentration in the transfer liquid + the liquid film accompanying the activator concentration on the transfer liquid surface and the resistance force to inhibit film extension due to the liquid viscosity) It can be concluded.
Here, as a factor (condition) that hinders the extension of the transfer film F, not only the concentration (ratio) of the activator on the liquid surface but also the concentration in the transfer liquid is taken into account. This is because the concentration of the active agent dissolved in the transfer solution is gradually increased by repeating the process. In that respect, since it is possible to reduce or maintain the concentration of the activator in the transfer liquid by supplying new water, it is conceivable to prevent the transfer film F from being lowered by supplying new water. Incidentally, in this embodiment, new water supply is also performed in consideration of this point.

In addition, as the removal means 101 in the extension reduction preventing mechanism 10, not only the activator component K is driven to the side wall 22 by blowing air, but also other removal methods can be adopted. For example, the activator component K on the liquid surface is used. And a vacuum method for sucking in together with the transfer liquid L. That is, in this case, a suction nozzle is applied as the removing unit 101.
In the present embodiment, the compressed air blowing nozzle 102 of the extension reduction preventing mechanism 10 is provided together with the blower 26. However, the extension reduction preventing mechanism 10 is not necessarily provided together with the blower 26. In the case where the transfer film F can be extended to the periphery by removal of the agent component K), liquid flow, or transfer action (holding action) by the film holding mechanism 6, the blower 26 is deleted from the entire configuration of the hydraulic transfer apparatus 1. It is possible.

Next, the transfer film supply device 3 will be described. As an example, as shown in FIG. 1, the transfer film supply device 3 includes a film roll 31 formed of a rolled transfer film F, a heat roller 32 that heats the transfer film F drawn from the film roll 31, and a transfer film A guide conveyor 33 for supplying the film F to the transfer tank 2 is provided. The transfer film F is supplied to the transfer tank 2 by a guide roller 34 while passing between these members.
Here, in the above description, the transfer film F is fed out to the transfer tank 2 sequentially from the roll film roll 31. For example, the transfer film F cut into a rectangular shape from the beginning is transferred to the transfer tank 2 one by one. A so-called batch-type hydraulic pressure transfer is also possible in which the transfer target W is pressed from above. Incidentally, in the case of the batch type, since a liquid flow is not normally formed in the transfer tank 2, when the transferred object W after transfer is pulled up from the transfer liquid L, it is pulled up along the design surface, and FIG. As shown to a), it is pulled up diagonally.

Next, the activator coating device 4 will be described. The activator coating device 4 is provided, for example, at a stage subsequent to the heat roller 32 of the transfer film supply device 3 and includes a roll coater 41 that coats the transfer film F with a required activator. Here, in the embodiment shown in FIG. 1, the activator is applied to the transfer film F and then supplied to the transfer tank 2, but the structure and the like of the apparatus are changed and supplied to the transfer tank 2. -It is also possible to apply the activator from above onto the transfer film F in the liquid landing state.

Next, the transferred object transport device 5 will be described. The transferred object conveyance device 5 immerses the transferred object W into the transfer liquid L in an appropriate posture and pulls it up from the transfer liquid L. In the present invention, as described above, the liquid discharge position on the design surface The main feature is that the transfer target W is pulled up while maintaining PO at a substantially constant position. In order to perform such pulling up, it is rare that the design surface S1 of the transfer target W is a simple plane. Therefore, the transfer target conveying device 5 can cope with various design surface shapes. It is considered preferable to apply a manipulator (robot). However, since it is also possible to apply a conveyor as the transferred object transport apparatus 5, in the following description, the transferred object transport apparatus 5 to which the conveyor is applied will be described first. In particular, in the case of liquid flow, the transfer target W is pulled up along the design surface (to maintain the liquid discharge position PO at a substantially constant position), and if the design surface S1 is not complicated, a conveyor is sufficient. It can be applied to.
In addition, since the transfer target W is usually attached to the conveyor via a transfer jig (simply referred to as a jig J), the transfer target transporting device 5 is also a conveyor responsible for transporting in this embodiment. A structure including 51 and a jig holder 52 is basically used. That is, at the time of hydraulic transfer, the transfer target W is attached to the jig J in advance, and the jig J is attached to and detached from the jig holder 52 and set on the conveyor 51 (setting of the transfer target W). Is to do. Hereinafter, the conveyor 51 will be further described.
As shown in FIGS. 12 and 20, for example, the conveyor 51 lays a link bar 54 on a pair of link chains 53 arranged in parallel, and a jig holder 52 is arranged on the link bar 54 at a predetermined interval. The transfer target W is continuously immersed in and discharged from the transfer liquid L together with the jig J. Note that the robot automatically attaches the transferred object W (jig J) to the conveyor 51 on the immersion side and removes the transferred object W (jig J) from the conveyor 51 on the liquid discharge side after transfer. It can also be performed, or can be performed manually by an operator. In the case of a liquid flow ant, the conveyance speed of the transfer target W by the conveyor 51 at the time of immersion is set to be substantially synchronized with the transfer speed on the liquid surface of the transfer film F (that is, the liquid flow speed of the transfer liquid L). It is common to be done.

A specific configuration of the conveyor 51 will be described. As shown in FIG. 20 as an example, this is for a normal triangular conveyor section 55 that draws a conveyance path of an inverted triangle when viewed from the side (the apex located below the inverted triangle). The portion is defined as an immersion side wheel 56), and a liquid discharge side wheel 57 is added. The transferred object W is substantially immersed in a section from the immersion side wheel 56 to the liquid discharge side wheel 57, and the liquid discharge area P2 Is set at a position different from the immersion area P1. More specifically, the liquid discharge area P2 viewed from the plane is set so as to be clearly located downstream of the immersion area P1.
Incidentally, in the conventional transport mode using only the triangular conveyor section 55, the transferred object W is immersed only at the lower apex portion (immersion side wheel 56), which is, for example, a short time or instantaneous immersion. In this example, the immersion of the transfer target W is linear, and it can be said that the immersion time is secured long. As described above, in this embodiment, a relatively long distance from the immersion area P1 to the liquid discharge area P2 can be secured, the liquid level residual film F ′ is divided while the transfer target W is immersed, and both side walls are separated. This is a transport mode suitable for collecting in 22 parts. Further, since the distance from the immersion area P1 to the liquid discharge area P2 is relatively long (since the immersion of the transfer target W is not instantaneous), the movement of the transfer target W in the transfer liquid is accompanied by a large rotation operation. Therefore, this leads to prevention of sagging failure and residue defects. Of course, in order not to cause such a defect as much as possible, it is necessary to consider the moving speed and the liquid discharging speed of the transfer target W in the transfer liquid L, and it is preferable that the speed is as low as possible. In consideration of the properties, the upper limit is 2 m / min.
Further, in this embodiment, the section from the immersion side wheel 56 to the liquid output side wheel 57 sets the movement locus of the transfer target W in the liquid substantially horizontally. Moreover, the conveyor 51 takes the structure which connected the conventional triangular conveyor part 55 and the linear conveyor 58 part by the liquid discharge side wheel 57 on such a structure, and these structural members are demonstrated below.

As in the conventional case, the triangular conveyor section 55 is configured to be tiltable as a whole with the immersing side wheel 56 that hits the lower apex being the center of rotation, and is configured so that the immersing angle α of the transfer target W can be appropriately changed. ing. Incidentally, the immersion angle α here is an angle with respect to the transfer liquid surface (upstream side) of the design surface S1, as shown in FIG. 20, and as an example, a set range of about 15 to 35 degrees is assumed. Yes.
The linear conveyor 58 is also configured to be rotatable about the lower chain wheel 59 and has a so-called pantograph-like structure. This is because (the linear conveyor unit 58 is rotatable), even if the immersion angle of the transfer target W is changed by the rotation of the triangular conveyor unit 55, the transfer length of the entire conveyor 51 (the total length of the link chain 53). This is because the tension applied to the conveyor 51 needs to be maintained. In other words, by rotating the straight conveyor 58, the rotation free end side of this is functioned as a so-called tension pulley.
Here, the solid line portion in FIG. 20 (a) is a conveyance trajectory when the immersion angle α is relatively small (about 15 degrees as an example), and the solid line portion in FIG. 20 (b) is compared with the immersion angle α. This is a transport trajectory when the target is large (as an example, about 30 degrees). Incidentally, in this embodiment, since the portion from the liquid discharge side wheel 57 to the rotation center side (chain wheel 59) of the straight conveyor 58 is set as a fixed track, the liquid discharge angle β cannot be changed. (Fixed setting). In other words, in the embodiment shown in FIG. 20, the transfer target W is always pulled up at the same inclination angle as the design surface S1 (pull-up along the design surface), which is suitable for the case of liquid flow pear. This can be said to be a method of pulling up (suitable for making the liquid position PO substantially constant).

Although the liquid discharge side wheel 57 is given the name “wheel”, it is not necessarily a member that rotates as the link chain 53 travels. For example, as shown in FIG. However, it may be a guide member that smoothly guides this (so-called sliding contact).
The diameter of the liquid discharge side wheel 57 is preferably the same as or larger than that of the immersion wheel 56. If the liquid discharge side wheel 57 is small, the liquid discharge side wheel 57 is discharged when the transfer target W is discharged. This is because the peripheral speed (rotational speed) and the angle change around the outside of the liquid side wheel 57 become large (the speed difference with respect to the transfer liquid L becomes excessive). That is, in this conveyor 51, since the transfer speed (chain running speed) in the link chain 53 portion to which the link bar 54 is attached is maintained constant, the diameter dimension (rotation radius) of the liquid discharge side wheel 57 is When it becomes smaller, the peripheral speed (rotational speed) and the angle change of the transferred object W that goes around the outside of the wheel become larger.

In the embodiment shown in FIG. 20, the liquid discharge angle β is fixed and cannot be changed as described above, but the liquid discharge angle β can be made variable. That is, for example, as shown in FIG. 21, the conveyor track (link chain 53) is viewed from the side, and the conveyance track is formed to have a rectangular shape (particularly trapezoidal shape) as a whole. Here, the immersion side wheel 56 and the liquid discharge side wheel 57 are set in a fixed state (only rotation at a fixed position is possible), and the remaining two

chain wheels

59A and 59B are respectively connected to the immersion side wheel 56 and the liquid discharge side wheel 57. It is formed so as to be rotatable with respect to. That is, the

linear conveyor portions

58A and 58B on the immersing side and the liquid discharging side connected to the immersing side wheel 56 and the liquid discharging side wheel 57 are formed to be rotatable around the immersing side wheel 56 and the liquid discharging side wheel 57. Is.
Of course, also in this embodiment, since the transfer length of the entire conveyor 51 (the total length of the link chain 53) cannot be changed, when the immersion angle α of the transfer target W is changed, the liquid is discharged like a tension pulley. The straight conveyor section 58B on the side is also shaken to change the liquid discharge angle β. Therefore, in the present embodiment, although the liquid discharge angle β can be changed, this is a change related to the immersion angle α, and the liquid discharge angle β cannot be freely changed without any limitation. Incidentally, the solid line portion in FIG. 21 is a conveyance mode when the immersion angle α is large and the liquid discharge angle β is small, and the two-dot chain line portion in the figure is a small immersion angle α and a large liquid discharge angle β. It is a conveyance aspect in the case. Further, as a specific angle, for example, the immersion angle α can be changed when it is about 15 to 35 degrees, and the liquid discharge angle β can be changed when it is about 25 to 55 degrees.

20 and 21, the transferred object W is transferred substantially horizontally in the liquid between the immersion side wheel 56 and the liquid discharge side wheel 57. The transport mode is not necessarily limited to this, and for example, as shown in FIG. 22, a transfer mode in which the transfer target W is gradually raised in the above-described section is also possible. In this case, the transfer target W is lifted and transferred with an appropriate inclination angle (liquid discharge angle β) during transfer between both wheels. From this, after the immersion of the transfer target W, if only the liquid discharge side wheel 57 is gradually moved upward in the above section, the discharge angle β of the transfer target W is gradually increased. Is possible. Accordingly, if the liquid discharge side wheel 57 can be raised and lowered in FIG. 21, the liquid discharge angle β can be changed with a higher degree of freedom, and in some cases, the liquid discharge side wheel 57 can be changed without depending on the immersion angle α. It is.

In addition, the conveyor 51 described above is intended to ensure a certain amount of time and distance between the immersion area P1 and the liquid discharge area P2, so that the triangular conveyor section 55 and the linear conveyor section 58 are combined. However, it is also possible to configure the conveyor 51 with only the conventional triangular conveyor section 55. In this case, however, the jig leg JL shown in FIG. 20 is set to be slightly longer so that the transfer target W is submerged deeply in the liquid, and the distance from the immersion area P1 to the liquid discharge area P2. It is preferable to ensure a longer length. Of course, simply increasing the length of the jig leg JL increases the peripheral speed and angle change of the transferred object W that rotates around the outside of the immersion wheel 56 (the lower vertex of the triangular conveyor). It is necessary to determine the transfer mode and the like.
In addition, as mentioned above, since such a conveyor 51 is usually pulled up along the design surface, it is suitable for the case of liquid flow pear, but the conveyor 51 is also applied to the case of liquid flow ant. It is possible to do. In that case (in the case of liquid flow ants), it is only necessary to pull up the transfer target W along the design surface while also adding a horizontal transfer component in the liquid flow direction (pickup taking into account the liquid flow). For example, by incorporating a slide mechanism in the jig J for attaching the transfer target W in advance, and sliding the transfer target W in the horizontal direction by the liquid flow rate as the transfer target W comes out, the conveyor 51 It can be lifted with a liquid flow. In addition, the conveyor 51 constituted only by the triangular conveyor section 55 is divided into the immersive side and the liquid discharge side (each side of the triangle is discontinuous), and the speed and angle are set separately on the immersive side and the liquid discharge side. By making it possible, it is possible to raise the liquid flow.

In addition to the conveyor 51, for example, the robot 110 (a multi-joint robot, so-called manipulator) as shown in FIG. This is a preferable form in that the degree of freedom of movement of the body W is high. Also in this case, the transfer tank 2 follows the above-described form, and it is more preferable that the liquid level residual film F ′ is divided and discharged from the transfer tank 2 while the transfer target W is immersed. . In addition to the design surface purification mechanism 9, it is desirable to provide the liquid discharge area purification mechanism 8, the extension reduction prevention mechanism 10, and the like so that the transfer liquid L and the liquid discharge area P 2 can be cleaned at a high level.
In FIG. 1, reference numeral 111 indicating a broken line portion is a transfer robot hand for immersing the transfer target W in the transfer liquid L, and generally holds a jig J holding the transfer target W. Is. Also, in the figure, reference numeral 112 indicating a two-dot chain line portion is a transfer robot hand for lifting the transferred object W from the liquid and placing it on the conveyor C for UV irradiation process. In general, the jig J holding the body W is gripped.

Further, in the case of hydraulic pressure transfer (robot transfer) using such a robot 110, as described above, the angle / posture of the transfer target W can be changed more freely than the conveyor 51, so the liquid discharge position PO is substantially constant. The transfer target W can be pulled up more accurately while maintaining the same, and the liquid discharge speed can be easily controlled. In the case of robot transfer, the immersion angle α, the immersion speed, the moving speed in the liquid, and the like of the transfer target W can be set with a high degree of freedom.
It is also possible to arrange a plurality of robots 110 on the left and right of the transfer tank 2 to alternately perform from immersion to liquid discharge.

It should be noted that, even in the case of robot transfer or transfer by the conveyor 51, the separation distance between the liquid discharge position PO and the overflow tank 92 for forming the design surface separation flow is approximately during the liquid discharge of the transfer target W. It is preferable to keep it constant. In particular, it is preferable to pull up the transfer target W so that this distance is constant at 100 mm or less. This is for the purpose of preventing the defect that the bubbles A and impurities adhere to the design surface S1 of the transfer target W, and the transfer pattern having an uncured surface protection function attached to the design surface S1 is not flowed. (Preventing sagging defects). That is, by maintaining the overflow tank 92 at a substantially constant distance in the proximity position from the liquid discharge position PO (design surface S1), a flow (design surface separation flow LR) always having the same separation force on the design surface S1 during liquid discharge. In this way, the bubbles A on the liquid surface and the contaminants in the transfer liquid and on the liquid surface are excluded from the design surface S1, and the design surface S1 itself is also purified.

The hydraulic transfer device 1 is based on the above-described configuration, and hereinafter, a hydraulic transfer method will be described while explaining a transfer mode by the hydraulic transfer device 1.
(1) Supply of transfer film In performing the hydraulic transfer, first, the transfer film F is supplied to the transfer tank 2 in which the transfer liquid L is stored. Here, as described above, since it is preferable to form a transfer pattern that also has a surface protection function during hydraulic transfer (no need for a topcoat after transfer), the transfer film F is also formed on a water-soluble film. Use a transfer ink with a transfer pattern only, or use a curable resin layer formed between a water-soluble film and a transfer pattern, especially on a water-soluble film. When using the transfer film F in which only the pattern is formed, it is preferable to apply a liquid cured resin composition as the activator.

In this embodiment, when the transfer film F is supplied to the transfer tank 2, the transfer film F becomes a liquid film on the transfer liquid surface between the film holding mechanism 6 (conveyor 61) and the transfer film F, and the transfer film F extends. Is to remove the activator component K that lowers. For example, as shown in FIG. 1, the compressed air blowing nozzle 102 blows air to the liquid surface facing the spreading edge of the transfer film F, and the activator component K that accumulates (floats) there is supplied to the film holding mechanism 6. This is driven between the film holding mechanism 6 and the side wall 22 while turning around the action start end (starting pulley 62A). As a result, since the activator component K is always removed at the liquid level facing the spreading edge of the transfer film F, both side parts (both side edge parts) of the transfer film F are reliably transferred to the conveyor 61 as the film holding mechanism 6. It continues to reach and is transferred to the immersion area P1 (transfer position) while maintaining a substantially constant elongation rate.
The activator component K driven between the film holding mechanism 6 and the side wall 22 is preferably introduced into the overflow tank 75 (discharge port 76a) and then recovered. This is because the transfer film F is continuously collected (discharged) from 2 and the transfer film F is extended, and fine fluid pressure transfer is continuously performed.

(2) Immersion of transferred object After the transfer film F is ready to be transferred on the transfer liquid surface in this way, for example, the transferred object W held by the robot 110 is sequentially placed in an appropriate posture / immersion angle. It is introduced into the transfer liquid L at α. Of course, the immersion angle α can be changed as appropriate depending on the shape and unevenness of the transfer target W (design surface S1).
Here, in this embodiment, the immersion area P1 is somewhat separated from the liquid discharge area P2 that is subsequently pulled up from the liquid, and the time during which the transfer target W is immersed in the transfer liquid L is relatively long. It's long.
Further, the transfer film F on the liquid level is pierced by the immersion of the transfer target W as shown in FIG. 1 and a hole is opened, and the film remaining on the liquid level is not used for transfer. The liquid level residual film F ′. Therefore, in this embodiment, the liquid level residual film F ′ is recovered as soon as possible after transfer so as not to reach the downstream liquid discharge area P2, and this recovery mode will be described below.

(3) Dividing the liquid level residual film In collecting the liquid level residual film F ′, first, the liquid level residual film F ′ is flowed downstream of the immersion area P1 and upstream of the liquid discharge area P2. In this case, as shown in FIG. 1, air is blown onto the liquid level residual film F ′ after the transfer to divide the film. Thereafter, the liquid level residual film F ′ divided by the air is gradually sent to the both side walls 22 by air blowing, liquid flow or the like, and here, as shown in FIG. 4, overflow tanks 75 provided on the both side walls 22. It is collected by etc.

(4) Recovery of Liquid Level Residual Film In this embodiment, the overflow tank 75 (discharge port 76) uses the film holding mechanism 6 (conveyor 61) so as not to prevent recovery of the liquid level residual film F ′. Although the film holding action is released, it is not released before the overflow tank 75 (on the upstream side of the discharge port 76). For example, as shown in FIG. (Overlapping state). This is to ensure that the liquid level residual film F ′ is held on the conveyor 61 until the overflow tank 75 is reached, so that the liquid level residual film F ′ does not pull the transfer film F at the transfer position. The overflow tank 75 flows around the terminal pulley 62B of the conveyor 61 and falls into the overflow tank 75 and is collected.

In addition, the vicinity of the edge of the dividing line FL gradually approaches the side walls 22 by blowing or liquid flow while gradually dissolving and spreading as described above. For this reason, when recovering the liquid level residual film F ′, it is preferable to collect the entire lump portion of the dividing line FL and the scattered impurities of the dividing line FL in two stages, which is suitable for this. The structure is blocking means 77 provided in the middle of the discharge port 76 of the overflow tank 75. In other words, due to the presence of the blocking means 77, even in one overflow tank 75, the liquid level residual film F ′ is recovered in two stages before and after the blocking means 77. Specifically, as shown in FIG. 9A, the entire lump of the dividing line FL is guided upstream from the blocking means 77 (the dam plate 78 or the accommodating shield 79) and recovered at the first stage in front. On the other hand, the scattered impurities on the dividing line FL are collected in the second stage behind the blocking means 77.

Further, the blocking means 77 also narrows the flow velocity induction range of the discharge port 76. For this reason, the blocking means 77 also performs control to weaken the flow rate after the release of the film holding action.
In this way, the liquid level residual film F ′ divided by the air is reliably recovered by the overflow tank 75 without adversely affecting the transfer position (immersion area P1).
Here, as the blocking means 77, as shown in FIGS. 4 and 10, it is possible to apply a dam plate 78 or a housing shield 79, but if it is a housing shield 79, it is dropped into the overflow tank 75. This is preferable because it can be fixed alone, and the accommodation type shield 79 can be slid back and forth to easily set the position with respect to the discharge port 76 and easily adjust the recovery rate performed in two stages.
In addition, such collection | recovery of the liquid level residual film F 'is naturally completed upstream from the liquid discharge area P2.

(5) Liquid discharge area purification (decoration unnecessary surface side)
Further, along with the recovery of the liquid level residual film F ′, in this embodiment, the liquid discharge area purification mechanism 8 purifies the liquid discharge area P2, particularly the decoration unnecessary surface S2 side, which will be described below. . The liquid discharge area purification mechanism 8 is configured to keep the impurities in the transfer liquid and on the liquid surface in the liquid discharge area P2 and the bubbles A on the liquid surface away from the liquid discharge area P2 and discharged outside the tank. For example, as shown in FIG. 4, overflow tanks 82 are provided on the left and right side walls 22 of the liquid discharge area P2, and a side separation flow LS from the liquid discharge area P2 toward the overflow tank 82 is formed. Thus, mainly contaminants in the liquid such as film residue are kept away from the liquid discharge area P2 and are collected. Further, in this embodiment, as shown in FIGS. 1, 2, and 4, a blower 85 is provided on one side wall 22 (above the overflow tank 82) of the transfer tank 2, and from there through the liquid discharge area P2, the opposite side The air is blown so as to reach the overflow tank 82. As a result, the bubbles A and impurities generated on the liquid surface in the liquid discharge area P2 (decoration unnecessary surface S2 side) are sent to the overflow tank 82 and collected. For this reason, it is preferable that the overflow tank 82 is provided with a flange 84 for increasing the flow velocity to increase the flow velocity (introduction speed) near the liquid surface.
In order to form the side separation flow LS, it is desirable to partially use fresh water.

(6) Liquid discharge area purification (design side)
In this embodiment, the design surface purification mechanism 9 purifies the design surface S1 side of the liquid discharge area P2. That is, when the mechanism pulls up the transfer target W, the design surface S1 of the transfer target W in the discharged liquid is purified, and the mechanism drops further from the transfer target W (jig J) pulled up earlier. The bubbles A on the liquid surface and the impurities on the liquid surface and on the liquid surface generated by the above are removed from the design surface S1 and removed from the liquid discharge area P2, and this will be described below.
During the discharge, the transferred object W is likely to generate a flow that wraps around the design surface S1 facing the downstream side or the traveling direction, and the design surface purification mechanism 9 eliminates such a wraparound flow as much as possible. This prevents dust and bubbles A from coming into contact with the surface S1. Specifically, as shown in FIGS. 1 and 2, an overflow tank 92 is provided in the liquid discharge area P 2, so that the transferred surface W (design surface S 1) in the liquid discharge is separated from the design surface by new water. A flow LR is formed. Here, the overflow tank 92 is preferably provided with a flange 94 for increasing the flow velocity, and the flow velocity (introduction speed) near the liquid surface is preferably increased (see FIGS. 4 and 12).
In order to further prevent dregs and sagging defects, the separation distance from the discharge position PO to the overflow tank 92 for forming the design surface separation flow is maintained substantially constant during the discharge of the transfer target W. Is preferable (for example, a constant distance of 100 mm or less), which is to cause the design surface separation flow LR to always act on the design surface S1 with the same strength. That is, in the case of liquid flow, the overflow tank 92 is set in a stationary state (fixed state) with respect to the transfer tank 2, and in the case of a liquid flow ant, it is moved in the liquid flow direction at the same speed as the liquid flow. Is.

By the way, in the conventional hydraulic transfer that performs the top coat after the hydraulic transfer and protects the surface of the transfer pattern, the water-soluble film adhered to the transfer target W (design surface S1) by performing water washing after the hydraulic transfer. Since the top coat was performed after the removal, the adhering of foreign matters such as film residue to the design surface S1 at the time of transfer does not immediately become defective. However, even in such conventional hydraulic pressure transfer, it is preferable to clean the liquid discharge area P2 and maintain the cleanliness of the transfer liquid L at a high level in terms of performing precise hydraulic pressure transfer. This is also preferable for the hydraulic transfer.

(7) Liquid discharge of transferred body The transferred body W is pulled up from the liquid discharge area P2 where the cleaning has been achieved at a high level as described above. There is almost no adhesion of A (reduction of defect rate).
In the present invention, the transfer target W is lifted from the transfer liquid L in an inclined state while maintaining the liquid discharge position PO on the design surface S1 substantially constant, and therefore basically the shape of the design surface S1 is obtained. The transferred object W is discharged along the line. However, only along the shape of the design surface S1, for example, a part of the to-be-transferred body W (design surface S1) that has been pulled up again may be re-immersed in the transfer liquid L due to the shape of the design surface S1 or the like. Thus, the transfer target W may be a main rotating operation, or a series of operations from immersion to discharge of the transfer target W may not be performed smoothly. For this reason, a liquid discharge virtual line CV that smoothly connects the design surfaces S1 is assumed so as not to cause these, and the liquid discharge angle on the design surface S1 or the liquid discharge virtual line CV may be pulled up along the design surface S1. β is set in the range of 25 to 55 degrees, and the liquid discharge posture of the transfer target W is controlled. Of course, the liquid discharge angle β can be gradually changed within the above range during the liquid discharge, or the liquid can be discharged while maintaining a constant value such as 34 degrees.
Further, in order to more effectively prevent defects and sagging defects, it is preferable that the liquid discharge speed of the transfer target W and the movement speed in the transfer liquid L be as slow as possible, but here also consider productivity. The upper limit is 2 m / min.

(8) Curing process of decoration layer The transferred body W pulled up from the transfer liquid L is then subjected to a process of curing the transfer pattern (decoration layer). Here, the transfer target W is irradiated with active energy rays such as ultraviolet rays (see FIG. 23C). At this time, the transfer target W is left with the semi-dissolved PVA attached to the design surface S1. It is a state. In addition, as another method for curing the transfer pattern (decoration layer), heating may be mentioned in addition to the above-mentioned active energy ray irradiation, but it is also possible to cure by both of them. Incidentally, the description “active energy ray irradiation and / or heating” described in the claims means that one or both of these curing processes are performed.
Thereafter, the PVA is removed from the transfer target W by water washing or the like (defilming), and after drying, a series of operations is completed. In this embodiment, since the transfer pattern (decoration layer) has already been cured, a top coat after drying is unnecessary. However, after that, further top coating can be performed.

(9) Transfer when the object to be transferred has an opening on the design surface Next, a preferable transfer mode when the object to be transferred W has the opening Wa on the design surface S1 will be described. For such a transfer target W, for example, as shown in FIG. 23A, transfer is performed by providing a thin film derivative 120 with an appropriate gap CL on the back surface (decoration unnecessary surface S2) side of the opening Wa. It is preferable to be immersed in the transfer liquid L. This is because, as it is, the thin film M stretched on the design surface S1 on the front side is stretched between the opening Wa and the thin film derivative 120 (gap CL) by the thin film derivative 120 as shown in FIG. .

Here, the reason (reason) that the thin film M that is normally stretched to the design surface S1 side can be stretched to the gap CL by the thin film derivative 120 will be described. The thin film M is generally similar to a soap bubble, and therefore has a property of stretching the film so as to reduce the area (surface area) (Fermer's law). For this reason, by providing the thin film derivative 120 so as to reduce the entire peripheral area of the gap CL (this is referred to as the separation total circumferential area) with respect to the area of the opening Wa (opening area), the thin film M is formed in the gap CL. It can be guided to the side (decoration unnecessary surface S2 side).
For this reason, as shown in FIG. 23A as an example, the thin film derivative 120 is substantially the same size as the opening Wa when viewed from the front, or slightly more than that. It is formed to be large, and this is a configuration for reliably forming the gap CL around the entire circumference of the opening Wa.
Further, when the thin film derivative 120 is positioned on the back side of the opening Wa, the thin film derivative 120 may be attached to the jig J, or the thin film derivative 120 is assembled using the back surface (assembled structure as an assembly). The derivative 120 may be directly attached to the transfer target W.

Incidentally, as an example, as shown in FIG. 23C, the thin film derivative 120 is preferably placed on the decoration unnecessary surface S2 side until the decoration layer is cured. Further, there is no particular problem with the thin film M being ruptured during liquid discharge or during the main curing process. This is because the thin film M is formed on the surface S2 of the transfer object W that does not require decoration, and the design surface S1 even if it ruptures. This is because it is difficult for the bubbles A due to the burst residue to be generated to the side.

Furthermore, the gap CL described above does not necessarily have to be formed constant with respect to the entire circumference of the opening Wa, and can be gradually decreased, for example, as shown in FIG. In this case, it is easy to induce air evacuation between the transfer target W and the thin film derivative 120 when the transfer is immersed, and precise fluid pressure transfer is possible. Moreover, quick drainage and drying after liquid discharge can be expected.

The present invention is suitable for the hydraulic transfer (hydraulic transfer that does not require a top coat) that forms a transfer pattern that also has a surface protection function at the time of transfer, but the transfer pattern is formed at the time of transfer, The present invention can also be applied to conventional hydraulic transfer for protecting the surface.
