Abstract

PROBLEM TO BE SOLVED: To provide an apparatus for manufacturing a transfer sheet to coat a strip-like base member with hot-melt ink in a thick film. SOLUTION: This apparatus contains a flat plate-like printing plate 29 made of resin and having heat resistance in an ink tray 30, and longitudinally moves it by a cylinder 39 between a forwarded position directly under a passing route of woody paper as a base member F and a rear retracted position. The printing plate 29 is coated with hot-melt ink by an ink plate 13 and a doctor blade 11 during longitudinal movement of the plate 29. The tray 30 is heated by a heater 36 to maintain the ink in a melted state. When the plate 29 is disposed at the forwarded position, a pressing pad 8 is vertically moved by a cylinder 7 to urge the woody paper F to the plate 29. Thus, the paper F is oozed and adhered with the ink from the plate 29. Since the ink is adhered directly to the sheet F by one time transferring without using a transfer pad, a printing fault such as omission of a printing pattern can be suppressed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of printing, and more particularly to the field of manufacturing transfer paper by printing a large number of predetermined print patterns at a constant pitch on a belt-like base member.

[0002]

2. Description of the Related Art Recently, an increasing number of sports enthusiasts have tools such as my balls on which their names and initials are printed. In this case, transfer paper is used to print initials and the like on the ball. This transfer paper is generally formed by printing a large number of predetermined print patterns (names and initials in this case) at predetermined intervals on a band-like base member made of a resin film, rough paper, or the like.
The pattern is transferred to the surface of the printing material by pressing the above-mentioned pattern against a printing material such as a ball and applying heat and pressure from the back surface.

[0003] Such transfer paper can be manufactured by a pad printing machine. In this pad printing machine, a plate-shaped printing plate having a predetermined printing pattern engraved as a concave groove and a printing material (in this case, a strip-shaped base member) are installed adjacent to each other, and the printing plate and the printing material are mounted. A transfer pad made of silicone rubber or the like is reciprocated along a gate-shaped path between the transfer pad and the transfer pad, and the ink is pressed against a printing plate applied in the concave groove of the pattern. Then, after the ink on the printing plate has been applied, the transfer pad is pressed against the printing material to transfer the ink constituting the printing pattern to the printing material.

[0004]

However, such a conventional pad printing machine can produce a transfer paper used for transferring a print pattern to an article having a smooth surface such as a golf ball or a bowling ball. For example, transfer paper used to transfer a print pattern to an article having a fluffy surface, such as a tennis ball, is difficult to manufacture with such a pad printing machine. This is because when a print pattern is transferred to an article having a smooth surface such as a golf ball, the ink film thickness may be small, but the print pattern is transferred to an article having a fluffy surface such as a tennis ball. In this case, if the ink film thickness is not large, the printed pattern floats from the surface of the article and good adhesion and transfer cannot be realized.And, in the pad printing machine, for the following reasons, This is because it is considered difficult to print such a thick film.

That is, conventionally, in a pad printing machine,
Generally, since a so-called solvent-based ink in which solid components such as a pigment and a binder are dispersed or dissolved in water or an organic solvent is used, the ink is attached from a printing plate to a transfer pad, and then the ink is added to the ink. If the ink is not transferred to the printing material after the solvent component contained is sufficiently volatilized and the viscosity of the ink is increased, the adhesive strength of the ink to the printing material is reduced, and the pad after transfer to the printing material is weakened. On the other hand, some ink remains, and the printing pattern is lacking on the printing material side, the printing density is insufficient, or ink bleeding and line thickening occur on the printing material surface. However, if the ink is applied to the transfer pad from the printing plate and then waits for the volatilization of the solvent component in the ink in time, the printing ability does not increase. The amount of ink adhered to the pad is reduced so that the solvent component in the ink is easily volatilized. As a result, in a conventional pad printing machine, since the amount of ink to be transferred is small, it is difficult to perform film thickness printing as obtained by, for example, screen printing.

One solution to this problem is not to use the solvent-based ink as described above, but to use an ink having a low solvent content and a high viscosity, for example, containing no water or an organic solvent. It is conceivable to use a hot-melt type ink that is excellent in volume feeling and adhesion by mixing a pigment and the like with a hot melt adhesive having a% solid content composition. In addition, the printing plate is heated to the melting temperature of the ink. In this regard, it is proposed that the ink be applied to the printing plate in a state of being melted by heat and attached to a pad.

However, since the pad printing machine transfers ink from the printing plate to the printing material through a transfer pad that reciprocates between the printing plate and the printing material, the transfer pad serving as the medium is also used. If the ink is not always heated to the melting temperature of the hot-melt ink, the ink adhered from the printing plate adheres to the pad, sticks, and is not transferred well to the printing material side. Therefore, a device for heating the pad is also required, and the entire printing press becomes large.

Further, even if the transfer pad is heated, the ink having such a high viscosity and high adhesiveness is once adhered to the pad until the ink is transferred from the printing plate to the printing material, and the transfer is performed twice. It is not preferable to perform the process, since the possibility of poor transfer to the final print is increased accordingly.

Therefore, at present, transfer paper on which a pattern is printed with a film having a high solid content and high adhesiveness by a thick ink is a rotary type using a cylindrical plate cylinder instead of a pad printing machine. Gravure printing machine. The principle will be described with reference to FIG. 4. A cylindrical printing cylinder a having a predetermined printing pattern formed as a concave groove on the peripheral surface is immersed in an ink tray b, and excess ink is removed by a blade c. While rotating in the direction of arrow d, and passing the base member f between the plate cylinder a and the pressing roller e in the direction of arrow g, ink on the base member f in the groove of the plate cylinder a is removed. It is transferred directly. According to this, there is no equivalent to the transfer pad in the pad printing machine, so that an extra heating device is not required, and the ink applied to the plate cylinder a can be printed on the base member f by one transfer. it can.

However, in this method, since a cylindrical plate cylinder, which is significantly more expensive than a plate-shaped printing plate used in a pad printing machine, is used, the production cost of transfer paper is high, and especially, However, in the case of personal consumption rather than the use of a maker which consumes a large amount, printing is performed in a small amount, so that the printing cost is significantly increased.

In view of the above-mentioned situation, the present invention is to print a highly viscous, voluminous ink on a base member in a pattern to a film thickness so that an ink such as a tennis ball does not easily adhere to the base member. It is an object of the present invention to provide an apparatus capable of inexpensively and suitably producing transfer paper for printing.

[0012]

In order to solve the above problems, the present invention uses the following means.

First, an invention according to claim 1 of the present application (hereinafter referred to as "first invention") is an apparatus for manufacturing a transfer paper in which a plurality of predetermined printing patterns are printed on a band-shaped base member at regular intervals. A driving means for moving the printing plate on which the printing pattern is engraved as a concave groove back and forth between a predetermined forward position and a retracted position, and a period until the printing plate returns from the forward position to the next forward position. Coating means for applying ink to the grooves of the printing plate, conveyance means for intermittently conveying the base member through the advance position, and the printing plate at the advance position, and the base member is stopped to be conveyed. And a pressing means for pressing the base member against the printing plate.

According to a second aspect of the present invention (hereinafter referred to as "second invention"), in the first aspect, the coating means includes an ink tray and a cam member which are moved back and forth by a driving means together with the printing plate. And a plate member which is driven by the cam member to supply ink of the ink tray to the surface of the printing plate when the printing plate, the ink plate and the cam member are moved from the advanced position to the retracted position. When the printing plate, the ink plate and the cam member are moved from the retracted position to the advanced position, the cam member is driven by the ink member to remove excess ink supplied to the surface of the printing plate to the ink plate. And a blade member to be used.

Further, the invention according to claim 3 (hereinafter referred to as “third
Invention ". In the first or second aspect of the present invention, the ink applied to the grooves formed in the printing plate is a hot-melt ink, and the base member is pressed against the printing plate by a pressing means. A heating means for heating the ink to a melting temperature until the ink is transferred to the base member, and a cooling means for cooling the ink after the ink is transferred to the base member are provided.

The invention according to claim 4 (hereinafter referred to as “fourth
Invention ". ) Is characterized in that, in any of the first to third inventions, the band-shaped base member is band-shaped rough paper.

By using the above means, each of the above-mentioned inventions operates as follows.

First, according to the first invention, a printing plate (intaglio) in which a printing pattern to be transferred is engraved as a groove is moved back and forth between a predetermined forward position and a backward position by a driving means. In this case, the ink is applied to the concave groove of the printing plate during one reciprocating movement of the printing plate from the advance position to the next advanced position. On the other hand, the base member is intermittently conveyed through the advance position of the printing plate by the conveying means, and when the printing plate is at the advanced position and the conveyance of the base member is stopped, the base member is pressed by the pressing means. Is pressed against the printing plate. As a result, the ink is transferred from the printing plate to the base member, and the print pattern is printed.

As described above, in the transfer paper manufacturing apparatus according to the first aspect of the invention, the printing plate is advanced onto the conveyance path of the base member as a printing material, and the base member is directly pressed against the printing plate to make contact therewith. By doing so, the ink is transferred to the base member at one time, so that a transfer pad such as that provided in a pad printing machine becomes unnecessary, and the transfer is not performed twice. As a result, Even when the film thickness printing is performed, problems such as transfer failure such as chipping of a print pattern on the base member as a printing substrate and printing failure are suppressed.

Further, since the operation at the time of printing is the same as the pressing operation of the transfer pad in the pad printing machine, it is also used in a conventional rotary press which prints ink on the base member in one transfer. It is possible to use an inexpensive flat plate printing plate used in a pad printing machine instead of a costly cylindrical plate cylinder. The printing cost for the consumer can be reduced.

In this case, an intaglio plate formed by etching a metal plate such as steel can be used as the printing plate. Alternatively, a positive film is brought into close contact with the photosensitive resin surface and exposed, and then exposed. It is also possible to use a resin intaglio created by washing out the part. In particular, the latter resin plate can be easily and inexpensively prepared compared to the former metal plate, and thus is preferable for personal printing in a wide variety of small-quantity production.

On the other hand, according to the second aspect of the present invention, the configuration of the application means is further embodied. According to this, the application means includes an ink tray and a cam member which are moved back and forth by the driving means together with the printing plate, and the cam. A plate member and a blade member driven by the member are provided. The plate member is driven to supply ink from the ink plate to the surface of the plate when the plate, the ink plate and the cam member are moved from the forward position to the retracted position, and the blade member When the printing plate, the ink plate and the cam member are moved from the retracted position to the advanced position, the printing plate is driven to remove excess ink supplied to the surface of the printing plate to the ink plate, As a result, one printing operation is completed, and ink is applied to the groove of the printing plate during one reciprocating movement of the printing plate until the next printing operation is performed.

As described above, in the transfer paper manufacturing apparatus according to the second invention, in particular, the cam member which is moved back and forth with the printing plate by the ink applying operation, and the plate member which is driven by the back and forth movement of the cam member And through the blade member, it is not necessary to separately provide a drive source for individually driving the plate member and the blade member, and the device can be made compact and the running cost can be reduced. .

Further, according to the third invention, particularly when the ink is a hot-melt ink mainly composed of a hot-melt adhesive capable of printing a film thickness suitable for tennis ball transfer paper, Until the ink is transferred to the base member, it is heated to the melting temperature by the heating means, and after being transferred to the base member, it is cooled by the cooling means,
Until the transfer of the ink to the base member, the ink is in a heat-melted state, so that the application to the printing plate and the transfer from the printing plate to the base member are suitably realized, while the ink is transferred to the base member. After the transfer, the solidification of the ink is promoted, and the subsequent processing of the band-shaped base member, for example, the winding operation or the like can be performed at an early stage.

As described above, in the transfer paper manufacturing apparatus according to the present invention, since a member corresponding to a transfer pad in a pad printing machine is not required, the hot-melt ink is maintained in a molten state. Therefore, the number of members to be heated is reduced correspondingly, so that the apparatus can be made compact, the running cost can be reduced, and the like.

In this case, since the printing plate to which the ink is applied is also heated, when the above-mentioned resin intaglio is used as the printing plate, sufficient heat resistance to the melting temperature of the ink is obtained. Use a resin intaglio. Furthermore, since a hot-melt ink capable of printing a film thickness is used as the ink, a sufficient effect of the printing of the film thickness can be exhibited by using a relatively deep groove having a depth of the resin plate. become.

According to the fourth aspect of the invention, in particular, a band-shaped rough paper is used as a base member which is a printing material in the transfer paper manufacturing apparatus. As described above, a resin film or the like is generally used as the base member,
By using this rough paper, when the rough paper is pressed against the printing plate, the liquid and fluid ink can easily penetrate and adhere to the rough paper, and the ink can easily come off from the printing plate completely. The operation and effect of facilitating and ensuring printing can be obtained.

In addition, a photo sensor 50 for detecting the position of the base member between the third guide roller 49 and the take-up reel 46 passes through the third guide roller 49 and is not wound on the take-up reel 46. Blower 51 that sends air to F
Is provided.

Next, with reference to FIGS. 1, 2 and 3, the operation of the transfer paper manufacturing apparatus 1 will be described according to the operation of one cycle.

Now, the pad 8 is mounted on the lift cylinder 7
1 and 2, the printing plate unit 28 is at the ascending position as shown by the solid line, and the printing plate unit 28 is at the advanced position by the advancing / retracting cylinder 39 as shown by the chain line in FIGS. At this time, the printing plate 29 in the printing plate unit 28
Is the pad 8 and the base member F passing thereunder.
It is located directly below.

Further, the doctor blade 11 and the ink plate 13 are both at the raised positions as shown by solid lines in FIG.
At this time, the rollers 17, 18 are connected via the connecting plates 21, 22.
Also rises integrally, and separates from the cams 37 and 38 attached to the attachment base 33 of the printing plate unit 28 immediately below. On the other hand, the driving of the base member winding motor 45 is stopped, and the conveyance of the base member F passing between the pad 8 and the printing plate 29 is stopped.

Further, the ink reservoir 30 of the ink tray 30
In a, a hot-melt ink in which a pigment or the like is mixed with a hot-melt adhesive is stored, and the ink is heated to a melting temperature by a heater 36 provided on the lower surface of the ink tray 30, and is maintained in a fluid state. ing.

From this state, the printing plate unit 28 is moved backward by the advance / retreat cylinder 39 as shown by the arrow A in FIG. 3, and is retracted to the retracted position shown by the solid line in FIGS. In this case, only the plate lifting / lowering cylinder 24 is operated downward, and as a result, the ink plate 13 and the plate roller 18 are lowered, and the roller 18 is brought into contact with the upper edge portion where the profile of the plate cam 38 is formed. Abut Therefore, with the retreating movement of the plate cam 38 in the printing plate unit 28, the ink plate 13
Is vertically driven via the rollers 18, the roller support rods 20, 20, the connecting plate 22, and the plate support rod 14, and the ink plate 13
The ink is stored in the ink storage unit 30a, and the ink in the hot melt state is scraped up and supplied to the surface of the printing plate 29.

When the printing plate unit 28 is retracted to the retracted position, the unit 28 is again moved forward by the forward / backward cylinder 39 as shown by the arrow B in FIG.
It is advanced to the advance position indicated by the chain line in FIG. In this case, the plate elevating cylinder 24 operates upward, and the blade elevating cylinder 23 operates instead. As a result, the doctor blade 11 and the blade roller 17 are lowered, and the roller 17
Abuts on the upper edge where the profile is formed. Therefore, this blade cam 37 in the printing plate unit 28
With the forward movement of the doctor blade 11, the doctor blade 11
7. The doctor blade 11 is vertically driven via the roller support rods 19, 19, the connecting plate 21, and the blade support rod 12, and the doctor blade 11 is marked by the ink plate 13 during the retreat movement of the preceding plate unit 28. It is driven to remove excess ink supplied to the surface of the plate 29 to the ink reservoir 30a of the ink tray 30. Again,
Since the ink on the printing plate 29 is heated and melted by the heater 36 and maintained in a fluid state, the ink is smoothly removed. As a result, the printing plate unit 28 returns to the forward position again, and when the printing plate 29 is located immediately below the pad 8 and the base member F, the ink is inserted into the concave groove 29a engraved as a printing pattern on the printing plate 29. Is applied. When the printing plate unit 28 has advanced to the forward position, the blade elevating cylinder 23 operates upward, and the doctor blade 11 and the roller 17 are raised.

On the other hand, the base member winding motor 45 is driven to rotate during one reciprocating movement between the forward and backward positions of the printing plate unit 28, and the photo sensor 50 detects the matching mark M. The driving is stopped based on.
As a result, the base member F is always conveyed at a constant pitch on which the matching marks M are provided.

In this state, the pad 8 is moved up and down by the elevating cylinder 7. In this case, the lower moving pad 8 captures the stopped base member F at its lower surface and presses it against the surface of the printing plate 29 at the immediately forward position as shown by the chain line in FIG. Thereby, the printing plate 29
The ink applied in the concave groove 29a and maintained in a flowing state by the heater 36 is attached to the base member F, and the print pattern is printed.

Thus, one cycle operation is completed, and the above operation is repeated to obtain a transfer paper having a predetermined printing pattern printed on the belt-like base member F at regular intervals.

The ink adhering to the base member F passes through the third guide roller 49, is cooled by the blower 51, and its solidification is promoted.

As described above, in the transfer paper manufacturing apparatus 1,
Since the printing plate 29 is advanced on the conveyance path of the base member F, and the base member F is directly pressed on the printing plate 29, the ink is transferred to the base member F at one time. Even in the case of using a hot-melt type ink that can be subjected to film pressure printing and has high adhesiveness as an ink, problems such as poor transfer such as chipping of a printed pattern on the base member F and poor printing are suppressed.

Since the printing operation is an operation of pressing the base member F against the printing plate 29 via the pad 8,
A low-cost flat plate-shaped printing plate can be used as the printing plate 29, so that the production cost of the transfer paper or the printing cost to the final consumer is reduced.

The operation of applying ink to the groove 29a engraved on the printing plate 29 is driven by the cams 37, 38 which are moved back and forth integrally with the printing plate 29 and the profiles of the cams 37, 38. Since the printing operation is performed during one reciprocation of the printing plate 29 via the ink plate 13 and the doctor blade 11, it is not necessary to separately provide a driving source for the ink application operation. Energy saving is achieved.

Further, the ink is heated to the melting temperature by the heater 36 until the ink is transferred to the base member F, and is cooled by the blower 51 after the ink is transferred to the base member F. It is possible to use a hot-melt ink having a large film thickness suitable for transfer to an article having a fluffy surface.

In this case, since no member corresponding to the transfer pad in the pad printing machine is provided, the number of members to be heated in order to maintain the hot-melt ink in the molten state is reduced correspondingly. The device 1 can be made compact and energy-saving.

A resin film or rough paper can be used as the base member F, which is a printed material in the apparatus 1. In particular, when rough paper is used as the base member F, the rough paper When pressed against the surface of the printing plate 29 by the downward movement, the liquid and fluid ink penetrates the rough paper and easily adheres thereto.
The ink easily comes off completely from the printing plate 29, and the printing of a film thickness suitable for the transfer paper for tennis balls is facilitated and assured.

As the plate-like printing plate 29 having the printing pattern engraved as the groove 29a, an intaglio plate formed by etching a metal plate can be used, but it is formed by exposing a photosensitive resin to light. The use of the intaglio made of resin makes it easier and cheaper to produce than the intaglio made of metal, so that it is preferable for personal printing applications of multi-product small-quantity production.

In this case, since the printing plate 29 to which the ink is applied is also heated by the heater 36, a resin intaglio having sufficient heat resistance to the melting temperature of the ink is used, and a sufficient film is used. The groove 29a having a relatively large depth is used so that thick printing can be performed.

Although not shown, a rotational braking force is applied to the support shaft 44 of the pay-out reel 43, and the matching mark M
In the case where the drive motor 45 is stopped by the detection of and the conveyance of the base member F is stopped, the feeding reel 43 continues to rotate by inertia and the base member F is prevented from being loosened on the conveyance path. .

[0058]

As described above, according to the transfer paper manufacturing apparatus of the present invention, the printing plate on which the printing pattern to be transferred is engraved as the concave groove is placed on the transfer path of the base member as the printing material. The ink is transferred to the base member at a time by directly contacting the base member with the printing plate, so that a member such as a transfer pad provided in a pad printing machine becomes unnecessary, and Since transfer is not performed twice, even when performing film thickness printing using, for example, a hot-melt ink, problems such as defective transfer, such as chipping of a printed pattern on a printing substrate, and defective printing are suppressed. You.

In this case, since the operation at the time of printing is the same as the operation of pressing the transfer pad in the pad printing machine, it is possible to use an inexpensive flat plate as in the case of the pad printing machine. This makes it possible to reduce the manufacturing cost of the transfer paper or the printing cost to the final consumer of small-volume printing. In particular, when a resin intaglio using a photosensitive resin is used, the effect is large.

Further, the operation of applying ink to the groove formed in the printing plate is performed during one reciprocating movement of the printing plate via a cam member or the like which is moved back and forth integrally with the printing plate. With this configuration, it is not necessary to separately provide a drive source for the ink application operation, and the apparatus can be reduced in size and energy saving such as running cost can be reduced.

Further, since the ink is heated to a melting temperature until the ink is transferred to the base member, and is cooled after the ink is transferred to the base member, it is possible to form an article having a fuzzy surface such as a tennis ball. It is possible to effectively use a hot-melt ink having a large film thickness suitable for transfer.

Further, in this case, since there is no member corresponding to the transfer pad in the pad printing machine, the number of members to be heated to maintain the hot-melt ink in a molten state is reduced accordingly. Energy saving such as downsizing of the device and reduction of running cost is achieved.

In particular, when the rough paper is used as the base member, when the rough paper and the ink come into contact with each other, the ink permeates the rough paper and easily adheres thereto, and the ink easily comes out of the printing plate completely. Easy printing of film thickness,
Make sure.
