Description

  The present invention relates to a hydraulic transfer apparatus that decorates the surface of a substrate to be transferred by hydraulic transfer.

  In automobile interior parts (for example, console boxes, instrument panels, armrests, steering wheels, etc.), products that have been decorated with water pressure transfer on their surfaces have been put to practical use in order to improve design and quality ( For example, see Patent Documents 1 and 2). Here, hydraulic transfer is a technique in which a water-swellable film is floated on the surface of the water, and a predetermined pattern printed on the film (pattern such as wood grain pattern or geometric pattern) is transferred to the surface of the molded body by water pressure. Yes, printing on a three-dimensional curved surface can be performed accurately and easily.

  In a conventional hydraulic transfer device, a transfer film is fed out from a film supply device, and the transfer film is floated on the water surface of a transfer tank and sent out. A flow at a constant flow rate is formed in the water in the transfer tank, and the transfer film is placed on the flow and transferred, and the transfer film is expanded.

As shown in FIG. 8, the transfer tank 50 for storing the water W1 is provided with a guide chain 51 at a position on both sides so that a part of its upper end is exposed from the water surface. When the transfer film 52 comes into contact with the exposed side surface of the guide chain 51, expansion of the transfer film 52 in the width direction is restricted and the transfer film 52 is guided along the direction of water flow. Then, the substrate 53 to be transferred is pressed so as to be submerged from above the transfer film 52 by a robot or a conveyor (not shown), so that water pressure is applied and the design of the transfer film 52 is transferred to the surface of the substrate 53 to be transferred. The

  However, as in the case of the substrate 53 to be transferred shown in FIG. 8, in addition to the surface 53a facing the transfer film 52, transfer is performed to a portion of the standing surface 53b that forms a predetermined angle with the surface 53a, or the back surface (FIG. 8, the transfer film 52 is pulled between the guide chain 51 and the transferred substrate 53, so that the standing surface 53 b and the back surface are brought into contact with the front surface 53 a. Compared to the pattern elongation. As a result, design variations occur between the standing surface 53b, the back surface, and the front surface 53a.

  Incidentally, in Patent Document 1, a blower is provided on the transfer film receiving side in the transfer tank. By blowing from the blower, the liquid landing position of the transfer film becomes constant, and the transfer is performed stably. Also in Patent Document 2, a blower is provided on the receiving side of the transfer film, and the transfer film is extended on the water surface by being blown from the blower. When such a blower is provided in the transfer tank 50 of FIG. 8, since the wind pressure acts on the entire transfer film 52, expansion of the transfer film 52 is promoted and the transfer film 52 is reliably brought into contact with the guide chain 51. The Rukoto. In this case, since the transfer film 52 is pulled between the guide chain 51 and the substrate 53 to be transferred, the problem of pattern elongation at the time of transfer cannot be solved, and the design of the substrate 53 to be transferred varies.

  The present invention has been made in view of the above problems, and its purpose is to release the restriction of the hydraulic transfer film by the guide means before the transfer substrate contacts the hydraulic transfer film, and An object of the present invention is to provide a hydraulic transfer device that can reliably perform hydraulic transfer to a substrate.

[First Embodiment]

  DESCRIPTION OF EMBODIMENTS A first embodiment embodying the present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic configuration diagram showing a hydraulic transfer device 1 (hydraulic transfer device) in the present embodiment.

  As shown in FIG. 1, a hydraulic transfer device 1 uses a transfer film 2 (hydraulic transfer film) having swelling properties to form a substrate-shaped transfer material 3 (for example, a box-shaped resin molding such as a console box). It is a device that performs hydraulic transfer printing on the body. This hydraulic transfer device 1 includes a transfer tank 5 (liquid tank) that stores water W1 as a liquid, a transfer film feeding device 6 that floats and sends the transfer film 2 to the water surface of the transfer tank 5, and a substrate to be transferred. And a transfer robot (not shown) for transferring 3 and pushing it into the water from above the transfer film 2.

  The transfer tank 5 is divided into a main tank 11 and a sub tank 12 located on the rear side. A recovery pipe 13 is connected to the auxiliary tank 12, and the recovery pipe 13 is connected to a pump 15 via a filter 14. Further, the pump 15 is connected to the front side of the main tank 11 via the supply pipe 16. When the pump 15 is driven, the water W1 in the main tank 11 leaks into the sub tank 12 beyond the side wall of the main tank 11, and the water W1 recovered through the recovery pipe 13 is filtered. After being filtered at 14, it is supplied again into the main tank 11. Thus, the transfer tank 5 of this embodiment is a water tank in which water W1 circulates, and the surface flow (from the receiving side 5a that receives the transfer film 2 to the discharge side 5b that discharges the transfer film 2 ( Liquid flow) is generated on the water surface of the main tank 11. In this embodiment, the recovery pipe 13, the pump 15, and the supply pipe 16 constitute liquid flow generation means.

  The transfer film feeding device 6 has a plurality of film feeding rolls for continuously feeding the transfer film 2 and a plurality of feeding films 6 fed to the receiving side 5a of the transfer tank 5 in a state where tension is applied to the transfer film 2 fed from the film feeding roll. A tension roll, an activator coating device that coats the transfer film 2 with an activator, and the like are provided.

  The transfer film 2 is created by gravure printing a printed pattern layer on a substrate made of a water-soluble or water-swellable film. In addition, as a formation method of the printing pattern layer in the transfer film 2, well-known printing methods, such as screen printing, can be used besides gravure printing. A part (printed pattern layer) of the transfer film 2 is transferred onto the surface of the substrate 3 to be transferred by hydraulic transfer to decorate the surface. Examples of such a printed pattern layer include a wood grain pattern and a geometric pattern.

  The substrate of the transfer film 2 absorbs water by floating on the surface of the water and dissolves or swells. When the transfer substrate 3 is pushed in from above, it easily extends and follows the shape of the transfer substrate 3. Have the property of deforming. Specific examples of this base material include polyvinyl alcohol resin (PVA), dextrin, gelatin, glue, casein, shellac, gum arabic, starch, protein, polyacrylic amide, polyacrylic acid soda, polyvinyl methyl ether, methyl Copolymers of vinyl ether and maleic anhydride, copolymers of vinyl acetate and itaconic acid, polyvinylpyrrolidone, or cellulose derivatives such as cellulose, acetylcellulose, acetylbutylcellulose, carboxymethylcellulose, methylcellulose, hydroxyethylcellulose, soda alginate alone Alternatively, a water-soluble or water-swellable film such as a mixed resin is used.

  Resin for binder made of thermoplastic urethane resin such as polyester urethane, acrylic urethane, polycarbonate urethane, and acrylic resin such as polymethyl methacrylate, polyethyl methacrylate, polybutyl methacrylate, etc. A printing ink containing is used.

  As shown in FIGS. 1 and 2, a pair of guide chains 31 (guide means) are disposed along the longitudinal direction on both sides of the upper portion of the transfer tank 5. The guide chain 31 is stretched around sprockets 32 and 33 arranged at both ends thereof (the receiving side 5a and the discharging side 5b of the transfer tank 5). Then, by rotating the sprockets 32 and 33, the guide chain 31 is driven in the direction of the water flow in the main tank 11 at a speed approximately equal to the flow velocity.

  In the present embodiment, the sprockets 32 and 33 at both ends are provided at positions where part of them is exposed from the water surface. Further, a plurality of guide plates 34 (retracting means) for retracting the guide chain 31 downward are provided at the center of the guide chain 31. Each guide plate 34 is formed using, for example, a metal plate or a resin plate, and has a shape curved in a substantially arc shape. Then, when the guide chain 31 comes into contact with the surface of each guide plate 34, the traveling direction of the guide chain 31 is forcibly changed. Thus, by providing the sprockets 32 and 33 and the guide plates 34, the guide chains 31 are arranged on the receiving side 5a and the discharge side 5b of the transfer tank 5 in the upper circulation portion (in other words, the same as the water flow direction). While a part of the forward path portion moving in the direction is exposed from the water surface, at the center portion, the position where the distance from the water surface to the upper circumferential portion of the guide chain 31 is 5 mm or more by each guide plate 34 ).

  Next, the operation of the hydraulic transfer device 1 of the present embodiment will be described.

  First, the pump 15 is driven to circulate the water W <b> 1 of the transfer tank 5, thereby generating a surface flow for flowing the transfer film 2 on the water surface of the main tank 11. At this time, the guide chain 31 is driven so as to have a speed comparable to the surface flow.

  Then, the transfer film 2 is sent out from the transfer film feeding device 6 onto the water surface of the transfer tank 5. The transfer film 2 is guided by the water flow in the transfer tank 5 and between the guide chains 31.

  Each guide chain 31 is partially exposed from the water surface on the receiving side 5a of the transfer tank 5, and the transfer film 2 comes into contact with the side surface of the exposed portion, so that the transfer film 2 is expanded in the width direction. While being regulated, the transfer film 2 is guided along the direction of water flow (see FIG. 2A).

  Further, the transfer film 2 and the guide chain 31 are brought into a non-contact state by the guide chain 31 being retracted below the water surface at a position immediately before the transfer position P1 at which the transfer film 2 contacts the substrate 3 to be transferred. Then, the restriction of the transfer film 2 by the guide chain 31 is released (see FIG. 2B). Then, at the transfer position P1, the transfer substrate 3 is pressed from above the transfer film 2 by a transfer robot (not shown), so that water pressure acts and a part of the transfer film 2 (printed pattern layer) is transferred to the transfer group. It is transferred to the material 3 (see FIG. 2C). At this time, since the transfer film 2 is in a free state on the water surface, pattern elongation does not occur as in the prior art, and the surface 3a (surface facing the transfer film 2) of the substrate 3 to be transferred or standing The image is reliably transferred to the surface 3b (side surface formed at a predetermined angle with the surface 3a), and further transferred to the back surface (the surface on the depth side in FIG. 2).

  Further, at the position on the discharge side of the transfer film 2 from the transfer position P1, a part of the upper end of the guide chain 31 that has been retracted below the water surface is exposed to the water surface again. When the transfer film 2 comes into contact with the side surface of the exposed portion, expansion of the transfer film 2 in the width direction is restricted, and the transfer film 2 is reliably guided to the discharge side 5b.

  Further, the transferred substrate 3 after transfer is transported by a transfer robot (not shown) and carried out to a post-process (drying process) line.

  Therefore, according to the present embodiment, the following effects can be obtained.

  (1) In the hydraulic transfer device 1 of the present embodiment, the guide chain 31 is retracted below the surface of the water before the transfer position P1 at which the substrate 3 to be transferred contacts the transfer film 2. Accordingly, at the transfer position P1, the restriction of the transfer film 2 by the guide chain 31 is released, and the transfer film 2 becomes free. Then, the transfer film 2 is brought into contact with the substrate to be transferred 3 in the free state, and the pattern of the printed pattern layer on the transfer film 2 is transferred to the substrate to be transferred 3. In this way, the transfer film 2 is not pulled by the guide chain 31 and the transferred substrate 3 as in the prior art, and the pattern elongation of the transfer film 2 can be prevented. As a result, the pattern can be uniformly transferred to the front surface 3a, the standing surface 3b, and the back surface of the transferred substrate 3, and variations in the design of the transferred substrate 3 after transfer can be suppressed.

  (2) In the hydraulic transfer device 1 of the present embodiment, the guide chain 31 is retracted below the water surface, so that the guide chain 31 transports the substrate 3 to be transferred as when the guide chain 31 is retracted above the water surface. It will not get in the way. Further, in this case, a sufficient retreat space is secured under the water surface, so that the guide chain 31 can be easily retreated, and the water pressure transfer to the transfer target substrate 3 can be performed more reliably.

(3) In the hydraulic transfer device 1 according to the present embodiment, at the position on the discharge side 5b from the transfer position P1, a part of the guide chain 31 (upper circumferential portion) retreated below the water surface is exposed again on the water surface. Therefore, expansion of the transfer film 2 in the width direction is restricted by the exposed portion, and the transfer film 2 can be reliably guided to the discharge side 5b.
[Second Embodiment]

  Next, a second embodiment embodying the present invention will be described. In the present embodiment, the configuration of restriction release means for releasing the restriction of the transfer film 2 by the guide chain 31 is different from that of the first embodiment.

  Specifically, as shown in FIG. 3, in the hydraulic transfer device 1 of the present embodiment, a pair of guide chains 31 (guide means) are provided along the longitudinal direction on both sides of the upper portion of the transfer tank 5. Is arranged. The guide chain 31 of the present embodiment is stretched around sprockets 32 and 33 arranged at both ends, and a part of the upper end is exposed from the water surface. In the present embodiment, unlike the first embodiment, the guide chain 31 is not retracted below the surface of the water, and a part of the upper end of the guide chain 31 is exposed even at the transfer position P1 of the transfer film 2.

As shown in FIGS. 3 to 5, an air nozzle 41 that blows air A <b> 1 (gas) from both sides of the transfer film 2 to a position 5 to 30 cm before the transfer position P <b> 1 (position of about 30 cm in the present embodiment). Is provided. The air nozzle 41 is disposed such that the nozzle tip is directed obliquely downward on the inside of the transfer tank 5. More specifically, the air nozzle 41 is disposed outside the guide chain 31 so that the nozzle tip (outlet) is located directly above the guide chain 31 (the height from the water surface is about 3 cm). . Then, the nozzle tip has an angle of about 30 ° with respect to the direction of water flow (see FIG. 5A) and an angle of 10 ° to 20 ° with respect to the water surface (see FIG. 5B). Has been placed.
As shown in FIG. 6A, a slit type nozzle is used as the air nozzle 41. In this air nozzle 41, the length of the slit 40 provided at the tip of the nozzle is preferably 20 to 50 mm and the width is 3 mm or less. In this embodiment, the slit 40 having a length of 25 mm and a width of 1 mm is used. ing. The air nozzle 41 may be changed to a multi-hole type air nozzle 41b as shown in FIG. 6B or a pipe type air nozzle 41c as shown in FIG. 6C. In the air nozzle 41b of FIG. 6B, for example, a hole diameter of 1.5 mm, a pitch of 3 mm, and 16 holes 40b are provided at the nozzle tip. Further, as the air nozzle 41c in FIG. 6C, one having a pipe inner diameter φ of 4 to 10 mm is used.

  As shown in FIG. 3, the air nozzle 41 is connected to a decompression adjustment valve 43 via an air hose 42, and the decompression adjustment valve 43 is connected to an air compressor 44 that is an air supply source. Then, after the air A1 supplied from the air compressor 44 is adjusted to a predetermined pressure (pressure of 0.1 MPa or less) by the pressure reducing adjustment valve 43 to reduce the flow rate, a very small amount of air A1 is transferred from the air nozzle 41 to the transfer film 2. It is sprayed continuously toward the end of the. In the present embodiment, the air nozzle 41, the air hose 42, the pressure reducing adjustment valve 43, and the air compressor 44 constitute restriction release means (gas supply means).

  In the hydraulic transfer apparatus 1 configured as described above, the transfer film 2 is separated from the guide chain 31 by applying a very small amount of air A1 from the air nozzle 41 before the transfer film 2 contacts the transfer target substrate 3. It is brought inside the transfer tank 5. As a result, the restriction of the transfer film 2 by the guide chain 31 is released. At the transfer position P <b> 1, the transferred substrate 3 is pushed from above the transfer film 2, so that a hydraulic pressure is applied and a part of the transfer film 2 (printed pattern layer) is transferred to the transferred substrate 3. (See FIG. 4). At this time, since the transfer film 2 is in a free state on the water surface, it is reliably transferred to the surface 3a and the standing surface 3b of the substrate 3 to be transferred without causing pattern elongation as in the prior art. Is transferred to the back surface. Further, since the amount of air A1 blown from the air nozzle 41 to the water surface is extremely small, the transfer film 2 can be reliably flowed by the water flow without the water surface undulating and without wrinkling the transfer film 2. Further, by using the slit type air nozzle 41 as shown in FIG. 6A, the air A1 can be blown with a certain width according to the slit 40, so that the transfer film 2 is regulated by the guide chain 31. Can be reliably released.

  Even when the hydraulic transfer device 1 is configured in this manner, the pattern can be uniformly transferred to the front surface 3a, the standing surface 3b, and the back surface of the substrate 3 to be transferred, as in the first embodiment. It is possible to suppress variations in the design of the transferred substrate 3 after transfer.

  In addition, you may change embodiment of this invention as follows.

  In the first embodiment, the guide chain 31 is retracted below the water surface. However, for example, the guide chain 31 may be retracted in the lateral direction. If a space for retracting the guide chain 31 above the transfer tank 5 can be secured, the guide chain 31 may be retracted above the space.

  As shown in FIG. 7, in the transfer tank 5, the guide chain 31 is divided into two sets of chains, the receiving side 5 a and the discharging side 5 b, and the transfer substrate 3 contacts the transfer film 2. You may comprise so that the guide chain 31 may not be provided in the position P1. Even if it does in this way, the pattern elongation of the transfer film 2 can be prevented, without pulling the transfer film 2 mutually with the guide chain 31 and the to-be-transferred base material 3 like a prior art.

  In each of the above embodiments, the substrate 3 to be transferred may be embodied in parts such as an instrument panel, an armrest, and a steering wheel in addition to the console box. Of course, the substrate 3 to be transferred is not limited to automobile decorative parts, and may be embodied in parts such as home appliances and office supplies.

  In the hydraulic transfer device 1 of each of the embodiments described above, the transfer substrate 3 is transported to perform the hydraulic transfer by the transfer robot. However, the hydraulic transfer is performed using a transfer conveyor instead of the transfer robot. It may be configured to do.

  In each of the above embodiments, the invention is embodied in the hydraulic transfer device 1 that applies decoration to the surface of the substrate 3 to be transferred by hydraulic transfer, but the liquid is transferred using the pressure of a liquid other than water. It may be embodied in a pressure transfer device.
