Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an emulsion coating device for a screen printing plate, and is used to apply a predetermined amount of emulsion to a screen printing plate used for screen printing. By using an emulsion film in which a coating film made of emulsion is layered on the film thickness, the entire coated surface has a uniform coating thickness, and the preset emulsion film thickness makes it even sharper. The present invention relates to a device for applying emulsion to a screen printing plate, which makes it possible to obtain a screen printing plate on which lines are formed.

[Technical background of the invention and its problems] Conventionally, in order to apply an emulsion to a flat screen printing plate for this type of screen printing, silk, polyester, nylon fiber, or stainless steel wire having a predetermined mesh thickness has been used. This is done by sliding the front edge of a packet-shaped squeegee from below to above, with the leading edge of a packet-shaped squeegee in contact with a screen printing plate that is framed around a screen material woven into a mesh pattern. At that time, if the squeegee was moved manually, it required skill and it was extremely difficult to achieve a uniform coating thickness. In order to solve this problem, various apparatuses have been proposed which perform the process by mechanically moving a squeegee, one of which is a printing screen coating method and its apparatus disclosed in Japanese Patent Publication No. 58-53332. When applying from both sides of the screen printing plate, the IC squeegee is placed on both sides of the screen printing plate, and the IC squeegee is advanced until it comes into contact with the screen material surface, and the IC squeegee is tilted. The screen printing plate or squeegee is raised and lowered by varying the heights of the edges so that the emulsion flows out from the leading edge of the squeegee. According to this, since the emulsion is allowed to flow down from the leading edge of the squeegee, if the squeegee leaves the supernatant 1, the leading edge of the squeegee will scrape off half of it, making it difficult to achieve a uniform coating thickness. When the squeegee descends (this is done when a particularly thick coating is required), there is no kneading, the coating flows to the underside of the squeegee, and the coating is not uniform, resulting in extremely uneven coating thickness. Ta. In addition, in this regard, even if coating is applied from below from both sides at the same time, if the distance between the screen printing plate and the leading edge of the squeegee is not widened, even if the coating is repeated while they are in contact, the emulsion will eventually deteriorate. It was not possible to increase the thickness of the coating film, and in particular, even if a thickness was required only on the printed surface, this could not be achieved. Furthermore, the squeegees placed on both sides of the screen printing plate are moved forward and backward symmetrically and synchronously by a single cylinder, so when coating only one side, it is possible to coat both sides at the same time. The second squeegee was replaced by a bar or roller, which was cumbersome to replace, and it was extremely difficult to continuously automate the transition from double-sided coating to single-sided coating and vice versa. . On the other hand, when printing using a screen printing plate, it is necessary to apply the emulsion so that the ink is thinner on the ink-applied surface and thicker on the printed surface in order to achieve beautiful printing. However, the above-mentioned conventional apparatus has difficulty meeting this requirement due to the troublesome work described above.

In addition, an emulsion film in which a layered coating of emulsion of a predetermined thickness is releasably layered on the film base material surface is prepared, and this is placed below the surface of the screen material against the screen printing plate and leveled. After the screen material is set in the same shape, a suitable squeegee is used to manually spread the paint film on the surface of the screen material in order to infiltrate it with water or other infiltrating materials. There is. On the contrary, according to this, manual movement of the squeegee makes it difficult for the infiltrating material to infiltrate the coating film evenly over the entire coating surface, resulting in extremely uneven coating, and by the end of the work, there are areas that are not in contact. Since some residue may remain, it required skill to carry out the work to prevent this from occurring.

[Object of the Invention] The present invention was created in view of the drawbacks of the conventional methods and apparatuses, and it is possible to determine the thickness of the emulsion film in the screen printing plate, the coating thickness of the emulsion film, and the infiltration material in the coating film. Coating pressure and moving speed by coating supply member,
Furthermore, the thickness can be set arbitrarily by selecting the infiltrating material, etc., and the object is to have a uniform thickness over the entire coating surface so that sharp lines can be formed during printing.

[Summary of the Invention] In order to achieve the above-mentioned object, the present invention includes a base having left and right side walls facing each other erected on the left and right sides of the base, and a base formed of a frame; An emulsion film consisting of a peelable layer of an emulsion coating of a predetermined thickness that can be wetted onto the surface of the film base material is closely supported on the support plate, and a flat screen printing plate is pressed on the front surface of the emulsion film. A support mechanism has a clamp for fixing the material, a coating lifting mechanism that lifts and lowers the coating supply member holding the material to be infiltrated into the coating film along the screen material in front of the screen printing plate, and The coating supply member is moved forward onto the material surface, its front edge is brought into contact with the screen material, and the screen is tilted. It consists of a coating operation mechanism disposed on the front side of the printing plate and a control mechanism that controls the raising/lowering, advancement, tilting, horizontal return, and retreat of the coating supply member. It was successfully berthed.

[Embodiments of the Invention] The present invention will be described in detail below with reference to the drawings.

Reference numeral 1 shown in the figure is an emulsion film, and this emulsion film 1 has a sheet-like film base 2 made of synthetic resin.
A coating film 3 made of an emulsion such as a photosensitive emulsion or a resin film with a predetermined thickness that can be soaked into one side is removably layered, and the thickness of the coating film 3 has a predetermined mesh. This corresponds to the thickness of the emulsion film to be applied to a flat screen printing plate S formed by a frame 1 surrounding a screen material M made of silk, polyester, nylon I1m, stainless steel wire, etc. woven in a mesh shape. However, it is selected appropriately taking into consideration that it will be coated within the mesh of the screen material M.
For example, it may be 15.20.25.30μ, etc.

This emulsion film 1 is such that three coated surfaces thereof are held in contact with the printing surface (print surface) of a screen printing plate S which is appropriately supported in the form of a standing leg. In this state, the ink application surface (squeegee surface) on the screen printing plate S
The infiltrating material held therein is applied and supplied by the application supply member 35 in the form of a packet or a band made of elastic material that rises with a force, and the infiltrating action of the infiltrating material on the coating film 3 causes the infiltration to occur. The coating film 3 is applied closely to the surface of the screen material M.

At this time, it is sufficient for the infiltrating material held by the coating supply member 35 to infiltrate the coating film 3 so as to dissolve it, and to bring it into close contact with the surface of the screen material M in that state, such as water, photosensitive emulsion, etc. Emulsions are planned, and water or liquid emulsions alone or a mixture of both are used.

Therefore, the present invention provides a base 10 that can be installed at an appropriate location.
, a support mechanism 20 that supports the emulsion film 1 and the screen printing plate S in a erected form in close contact with each other, and a coating system that applies and supplies the infiltrating material by raising and lowering the coating supply member 35 on the front side of the screen printing plate S. The challenge is to use one that consists of an elevating mechanism 40 and a control mechanism 70 that controls the coating supply by the coating supply member 35.

As shown in FIG. 1, the base 10 has left and right side walls 12.13 facing each other erected on the left and right sides of the base 11 which is horizontally adjusted and installed by the adjuster 15. It is constructed by constructing earthen walls 14 between them. As shown in the figure, operation panels 72 and 73 are attached to the front surface of the left side wall 12 to preset various controls by the control mechanism 70, as will be described later, and a lifting motor 41, which is a drive source for the coating lifting mechanism 40, is installed in the lower part. It is stored.

In the working space between the left and right side walls 12 and 13 of this base 10, the emulsion film 1 and the screen printing plate S
A support mechanism 20, a coating lift mechanism 40, and a coating operation mechanism 50 are incorporated, respectively, for setting and coating the infiltrating material to apply coating II 3 to the screen material M.

As shown in FIGS. 1 and 2, the support mechanism 20 is supported between the fixing bars 21 installed horizontally between the upper and lower parts of the left and right side walls 12 and 13, so that the support mechanism 20 can be mounted vertically or vertically on the base 10. In some cases, the emulsion film 1 is closely supported with the coated film 3 facing forward on a support plate 22 which is tilted and fixed to a standing position, and a clamp 26 is attached to press and fix the screen printing plate S on the front surface of the emulsion film 1. It consists of In order to suppress and fix the screen printing plate S to the support plate 22, the lower fixing bar 21 has a clamp die 24 whose rear surface is inclined so that the width gradually becomes narrower as it goes downward between the front surfaces of the support plate 22. At the same time as fixing the support plate 2
2 At the front of the upper part, 11 The left and right side walls 12 can be slid freely in the downward direction.
．． 13, a clamp fixing bar 25 installed between them, and the front surface of the support vA22, which gradually becomes narrower as it goes upwards. 26 is installed. By doing this, when the screen printing plate S is inserted between the clamp die 24 and the support 122 and the clamp 26 is operated, the inclined surfaces of the clamp dies 2/11 and the clamps 26 will move the screen printing plate S onto the support plate. 22 Press evenly on both sides,
The screen material M of the screen printing plate S can be supported in close contact with the emulsion film 1 that is brought into close contact with the support plate 22, and,
Although it has a simple 4 [configuration], it is possible to achieve a reliable set-up.

Moreover, pines 1 to 23 made of elastic material are attached to the front surface of the support plate 22. The mat 23 itself is made of rubber or an elastic material similar to rubber and is shaped like a sheet with a predetermined thickness. When the emulsion film 1 is closely attached to the front surface of the mat 23, special temporary fixing or It can be reliably supported in a predetermined position by electrostatic action without providing support and fixing means. In addition, when the coating supply member 35 supplies the infiltrating material F4-D to the front surface of the screen material M in order to coat the coating film 3 of the emulsion film 1 on the screen U IV1 surface, the coating supply member 35 rises while pressing the screen material M with a predetermined pressing force, the elastic action of the pines 1 to 23 themselves applies appropriate tension to the screen material M, and it rises while contacting the screen material M. This is done to ensure smooth movement of the coating supply member 35.

FIG. 6 shows an embodiment in which a film supply mechanism 30 is attached, in which an emulsion film 1\1 to be cut to a required length is wound and housed. This film supply mechanism 30 is configured such that a rolled emulsion film 1 is exchangeably mounted on a supply roller 31 installed between the upper portions of the left and right side walls 12 and 13. As a result, the emulsion film 1 can be continuously supplied and set, and can be used in any length, thereby improving work efficiency.

The coating operation mechanism 50 allows the printing surface (Print 1 to surface) of the screen printing plate S at the time of printing to be known;
As previously described, the infiltrating material is applied.

The coating lifting mechanism 40 raises and lowers the coating supply member 35 disposed on the front side of the screen printing plate S along the surface of the screen material M. Specifically, the coating lifting mechanism 40 includes a support to which the coating supply member 35 is detachably attached. Bar 55 on left and right side walls 12.13
The unit 45 is installed between the units 45 that are disposed facing each other on the left and right inside, and the unit 45 is connected to a chain 44 that is driven and circulated within the left and right side walls 12 and 13, respectively, and the left and right side walls 1.
2. Guide roller 4 along guide 42 set up in 13
It is designed to be raised and lowered via 7. That is, the sprocket wheels 43 are pivotally supported above and below the guides 42 which are installed in the left and right side walls 12 and 13, respectively, and the left side wall 12
The unit 45 is raised and lowered by driving and circulating the chain 44 which is looped around the sprocket wheel 43 by the lifting motor 41 housed in the lower part. The range of elevation of the unit 45 at this time only needs to be within the vertical interval of the screen printing plate S supported and set on the support mechanism 20. Upper and lower limit limits 1 to switch 48 are provided, the installation positions of which can be adjusted to reverse the drive of the lifting motor 41 when the unit 1-45 comes into contact with them. unit 45
The chain 44 refers to the guide 42 as shown in FIG.
The unit 45 is linked by being fixed to a chain 44 that is looped around on the back side with a linking part 46 protruding from the back side of the unit 45.

A guide roller 47 that is in contact with the front and rear edges of the guide 42 is pivotally supported on the linking portion 46, and as the guide roller 47 rolls along the guide 42, the unit 45 is rotated as the chain 44 is driven. The screen material M that is attached to the application supply member 35 is

On the other hand, the coating operation mechanism 50 advances the coating supply member 35 toward the screen +JM surface when the coating supply member 35 is on top of the coating supply member 35, with its front edge in contact with and tilting the coating supply member 35, and when the coating supply member 35 is lowered By returning the coating supply member 35 horizontally and moving it backward, it is separated from the screen lunar surface M.

The specific configuration of the coating operation mechanism 50 includes the left and right side walls 12 and 13.
A tilt arm 52 is swingably supported at the front part of the left and right units]~45, respectively, and the support bar 5
5 is a slide shaft 54 attached to an inclined arm 52.
A biscuit 58 of a reciprocating cylinder 57 fixed to the inclined arm 52 is installed between the inclined arms 52 facing each other on the left and right sides. , the unit 1 is attached to the inclined arm 52.
Screws 1 to 61 of the tilting cylinder 60 pivotally supported on the
It is made by connecting each.

As shown in the figure, when the coating and supplying member 35, which has been moved to the claw side of the support bar 55, coats and supplies the infiltrating material ID, it advances against the surface of the screen material M, and after its front edge comes into contact with the surface, it tilts. When the coating supply member 35 itself is tilted, the infiltrating material held therein flows out and infiltrates the coating film 3 of the emulsion film 1 through the mesh of the screen M. It is desirable that the front edge of the support bar 55 be centered on the axis.In other words, the support bar 55 should be moved between the inclined arms 52 in order to move the coating supply member 35 forward and backward in the horizontal direction so that it can advance toward the screens I and JM quickly and smoothly. The front edge position after the end of forward movement is on the left and right sides so that the tilting motion of the tilting arm 52 itself causes the tilting motion of the coating supply member 35, that is, tilting backward.
It is assumed that it is approximately on the same line as the 411th support position of No. 2. Therefore, the coating supply member 35 is operated centering on the screen material M of the screen printing plate S supported by the support m structure 20. The shaft support pin 51 is located on the unit 45 on the extension of the material M surface.

As shown in FIGS. 3 and 4, a pair of glue boats 53 are provided protruding from the inclined arm 52 so as to face each other at the front and rear thereof.
A slide shaft 54 is installed between these supports 53, and the front part of a reciprocating cylinder 57, which is located in front of the lower part of the front boat 53 and arranged horizontally, is fixed, and its piston 58 is attached to the slide shaft 54. It extends parallel to the support bar 55, and its tip is connected to a joint 59 projecting below the support bar 55. Further, the tilting cylinder 60 is disposed in a substantially vertical direction below the tilting arm 52, and the rear part of the cylinder is pivoted to the surface of the unit 45, and the tip of the piston 61 is connected to the tilting arm 52. Further, the support bar 55 is fitted to the slide shaft 54 via the pole bushing portions 56 formed at both ends thereof, thereby allowing the respective inclined arms 52 pivotally supported on the units 45 on the left and right sides of the base 10 to be connected to each other. It is said that it will be constructed in In this way, the ball bushing part 56
By adopting this, the movement of the support bar 55 along the slide shaft 54 has low friction, making the movement extremely smooth, and at the same time preventing the elongated support bar 55 from tilting and other movements, ensuring stable operation. do.

Here, to explain the operation of such a coating operation mechanism 50, according to the operation order set in advance for the control m+ mechanism 70, which will be described later, when the unit 45 itself is raised, the forward and backward movement cylinder is 57 operates to move the support bar 55 forward along the slide shaft 54, so that only the front edge of the coating supply member 35 comes into contact with the surface of the screen material M (see FIGS. 2 and 3). Then, the tilting cylinder 60 is actuated to apply the infiltrating material to the tilting arm 5.
2 is tilted and swung about its pivot position, the application supply member 35 is tilted, and the infiltrated material flows out into the screen material M.

Furthermore, when the units 1 to 45 themselves are lowered, the tilting cylinder 60 is activated to return the tilting arm 52 and the coating supply member 35 to the horizontal position, and then the advancing and retracting cylinder 57 is activated. Then, the support bar 55 and coating supply member 35 are moved back.

Then, the coating operation mechanism 40 protects the coating supply member 35, and the coating operation mechanism 50 moves the coating supply member 35 forward, tilting, and returning to the horizontal position.
There is a mechanism 70, which is composed of electrical and hydraulic and pneumatic circuits. In FIG. 5, the supply of working air pressure to a total of two left and right advancing/retreating cylinders 57 in the coating operation mechanism 50, and two left and right tilting cylinders 60 that tilt backward on the front side of the screen printing plate S, In addition, the clamp 2 in the support mechanism 20
An operating system path for supplying, exhausting, and shutting off operating air pressure to 6 is also formed.

In the figure, 74 is a pressure reducing unit, 75 is a switching valve, 76 is a muffler, 77 is a pressure reducing valve, and 78 is a speed controller, and these controls are controlled by the left side wall 1 as shown in FIG.
This operation is performed by operating various buttons and dials on the electrical section operation panel 72 and the pneumatic operation panel 73 provided on the front of the device 2, and enables automatic operation with various combinations of settings for the number of times of coating and supply as required.

The present invention is constructed as described above, and its use will now be explained with reference to FIGS. 1 to 4.

First, prepare an emulsion film 1 with a size corresponding to the size of the screen printing plate S, and closely support the emulsion film 1 on the front surface of the support plate 22 with the coated film 3 side facing forward, and then place the screen printing plate S on its printing surface. With the glue in close contact with the coating film 3, it is supported and fixed in the form of a standing leg with a clamp 26. On the other hand, the coating supply member 35 attached to the support bar 55 holds the infiltrating material, and is turned on by operating various buttons on the operation panel 72 and the start switch 71. Then, the coating operation mechanism 50
The forward and backward movement cylinder 57 operates to move the support bar 55,
The coating supply member 35 is advanced against the surface M of the screen material so that its leading edge is brought into contact with it, and then the tilting cylinder 60 is operated to tilt and swing the tilting arm 52, thereby moving the rear part of the coating supply member 35. Hold it upwards and tilt it to allow the infiltrated material to flow out onto the M side of the screen material. At this point, a variable timer can be used to arbitrarily set the time required for the infiltration material to blend into the surface of the screen material M. Then,
The coating operation mechanism 40 is activated and the chain 4 is driven and circulated.
4, the unit 45 is raised, and as a result, the support bar 55 installed between the left and right units 45 and the application supply member 35 also move upward, and the infiltrated material flows out from the application supply member 35 while rising. The liquid is applied and supplied to the surface of the screen material M. When the coating supply member 35 reaches the predetermined position, the upward movement of the coating supply member 35 is stopped, and the tilting cylinder 60 is activated again to return the coating supply member 35 to the horizontal position.
If necessary, it can be raised as it is 2
By doing so, the infiltrated material overflowing from inside the coating supply member 35 can be scraped and collected. Next, the coating supply member 35 is moved by the operation of the advance/retreat cylinder 57.
The coating elevator WJ40 operates in reverse to lower the unit 45, and the coating supply member 35 descends while being separated from the surface of the screen material M and returns to its original position.

This kind of application supply operation can be repeated multiple times if necessary, and if this is set in advance, - the number of completed application processes is counted each time the operation is completed, and automatic operation starts when the predetermined number of applications is completed. stops and the work is completed.

By doing this, the squeegee surface of the screen printing plate S is known and the infiltrating material is applied and supplied through the screen material M. During this time, the infiltrating material infiltrates into the coating film 3 of the emulsion film 1 to obtain an appropriate viscosity. The printing surface of the screen material M is coated with the wafer, and when the application and supply of the infiltrating material is completed, the support mechanism 20 releases the standing leg support, the screen printing plate S is taken out, and the film base material in the emulsion film 1 is coated. By removing 2, the plate frame is completed.

[Effects of the Invention] The present invention is configured as described above, and therefore, by making it correspond to the thickness of the coating film 3 on the emulsion film 1 and the coating pressure and speed of the coating supply member 35, so to speak, transfer can be performed. The formed emulsion film of a predetermined thickness can be applied to the surface of the screen material M, and as the coating supply member 35 rises, the infiltration film passes through the screen material M and infiltrates into the coating film 3. Since the emulsion film is obtained by the action of the film, the emulsion film is closely applied to the surface of the screen material M.

Therefore, an emulsion film 1 having a coating film 3 thickness corresponding to the thickness of the emulsion film required for the screen printing plate S is prepared, and the operation by the coating supply mechanism 40 and the coating operation mechanism 50 is controlled by a mechanism. 70 to control the coating supply pressure,
By selecting the speed and furthermore the infiltration material, it is possible to form an emulsion film with an accurate thickness all over the printing surface of the screen printing plate S, and to maintain an average infiltration rate over the entire coated surface. Since the emulsion is infiltrated with the emulsion, a uniform infiltration action is applied in just the right amount at any location, resulting in a smoother emulsion film.

In particular, the support mechanism 20 has a clamp 26 that closely supports the emulsion film 1 on a support plate 22 fixed to the base 10 and presses and fixes the flat screen printing plate S on the front surface of the emulsion film 1. Therefore, the screen material M of the screen printing plate S and the emulsion film 1 are in close contact with each other, and the coating supply member 35 is moved to the screen plate M by the coating lifting mechanism 40 and the coating operation mechanism 50.
When raised while in contact with the surface, the infiltrating material held by the coating supply member 35 is averagely infiltrated into the coating film 3 through the mesh of the screen material M, forming a uniform emulsion film. Further, the support plate 22 supports the entire emulsion film 1, reliably supports the flexible emulsion film 1 together with the screen printing plate S in a standing leg shape, and allows the coating supply member 35 to rise smoothly. This can improve work efficiency.

The coating operation mechanism 50 moves the coating supply member 35, which is raised and lowered along the screen width M on the front side of the screen printing plate S, to advance toward the surface of the screen material M when the coating supply member 35 is raised, and brings the leading edge into contact with the coating supply member 35.
Since it is arranged in front of the screen printing plate S in such a way that it is tilted and returned to the horizontal position when descending, and is moved away from the screen UM by retreating, the infiltration occurs only when the coating supply member 35 is raised. By coating and feeding at a monthly rate, the amount of infiltration and feeding can be quantified, ensuring the formation of a smooth emulsion film without dripping during coating and feeding.

As explained above, in the present invention, an emulsion film coated with an emulsion film of a predetermined thickness is held in close contact with a screen printing plate supported in the form of an upright leg, and then a predetermined coating process is performed. The emulsion film is formed by closely coating the coating film on the surface of the screen material by the infiltration action of the infiltration material supplied from the coating supply member, which increases according to the supply pressure and speed, so the work is no longer as troublesome as in the past. It is possible to form an emulsion film of a uniform predetermined thickness without the need for a screen printing plate, which is capable of forming even sharper lines during printing. It is effective.
