Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydraulic transfer printing apparatus for transferring a printed matter onto a work having a curved surface or an irregularly shaped surface.

[0002]

2. Description of the Related Art A print pattern support film comprising a liquid tank for storing a liquid, for example, water, and a print pattern to be printed on the surface of a thin film soluble in the liquid on the liquid surface in the liquid tank. A hydraulic transfer device provided with a printing pattern support film feeding device for feeding so as to float is known (see JP-A-51-21914).

In this type of hydraulic transfer device, the print pattern support film partially swells or dissolves in the liquid to the extent necessary for transfer when it comes into contact with the liquid surface, and the print pattern to be printed partially swells or melts. Floats above the liquid surface with the dissolved film. Therefore, when the surface to be printed of the work to be printed is immersed in the pressing liquid toward the printing pattern on the liquid surface, the printing pattern adheres to the surface to be printed by the liquid pressure. Therefore, when the work is pulled up from the liquid as it is and the film is washed away with the liquid, the transfer printing of the print pattern is completed.

This type of hydraulic transfer device is advantageous in that it can print an arbitrary printing pattern even if the surface to be printed is a non-planar surface such as a curved surface or an irregularly shaped surface. Suitable for printing on surfaces such as cabinets.

[0005]

By the way, the surface of the work to be hydraulically transferred is cleaned in advance by removing dust and degreasing before entering the hydraulic transfer device.
Further, the work on which the print pattern is transferred to the surface by the hydraulic transfer device is then sent to the coating device, and the work surface is coated by the coating device.

However, the dust removal and degreasing work performed on the work is performed in a process different from the hydraulic transfer work, and in reality, it depends on the manual work. Also, the painting work on the work is performed in a process different from the hydraulic transfer work. For this reason, it takes a long time from the dust removal and degreasing work to the work to the painting work after the hydraulic transfer work. Further, since each work process is independent, new dust or the like may be attached to the work surface when the work is transferred between the respective processes. The present invention has been made in consideration of such points,
To provide a hydraulic transfer printing facility capable of continuously and automatically performing dust removal and degreasing work on a work, hydraulic transfer work, and painting work and transferring a print pattern to a work in a clean state. The purpose is to

[0007]

According to the present invention, there is provided a dust removing and degreasing device for removing dust and degreasing by spraying a degreasing liquid on the surface of a work, and a water-soluble film having a printing pattern and floating on the water surface. A hydraulic transfer device for adhering to the work surface, and a film removing device for injecting water into the water-soluble film adhered to the work to dissolve the water-soluble film,
A coating device consisting of a plurality of coating booths for coating the surface of the work on which the printing pattern is transferred to the surface, the dust removing and degreasing device, the hydraulic transfer device, the film removing device, and the coating device in sequence. A common work transfer conveyor for transferring a work, wherein the coating device has a coating conveyor connecting between the booths, the coating conveyor is provided independently from the common work transfer conveyor, This is a hydraulic transfer printing facility.

[0008]

According to the present invention, the work of removing dust and degreasing work, the hydraulic transfer work, and the painting work can be continuously performed on the work. Also, because the coating conveyor in the coating device is provided separately from the common work transfer device, the common work transfer device is kept away from the easily contaminated paint conveyor while keeping it clean while Various work can be performed.

It is a figure which shows the state in 1b. As shown in FIG. 7, the coating robots 32a and 32b have arms 33a and 33b, respectively.
have. Then, the paint is sprayed from the tips of the arms 33a and 33b onto the work 8 on the booth conveyors 63a and 63b to coat the surface of the work 8.

As shown in FIG. 1, a baking / drying furnace 23 is provided downstream of the coating device 22 to dry the work 8 whose surface has been coated by the coating device 22 and solidify the coating material. The common work transfer conveyor 40 extends from the lateral line of the coating device 22 into the baking and drying oven 23, and then descends from the baking and drying oven 23 through the opening 43 to the first floor. After that, the common work transfer conveyor 40 moves the unloading unit 9

Further, in the above steps, in order to prevent the dust, which is generated and dropped from the conveyor 40, from adhering to the work, the work, the pallet, the pallet mounting jig, etc. are placed above the conveyor 40. , Support and fix it so that it can be transported freely.

Next, the operation of this embodiment having such a configuration will be described. 2 and 5, first, the work 8 to which the pallet mounting jig 115 is mounted is placed on the entrance side of the dust removing and degreasing conveyor 57. The pallet mounting jig 115 is a jig for fixing the work to the pallet on each conveyor. Next, the work 8 is conveyed into the degreasing chamber 51, and the degreasing liquid is jetted from the nozzle 93 to the work 8 in the degreasing chamber 51.

The work 8 is generally made of plastic or the like and has a curved surface or an irregularly shaped surface. In addition, the mold release agent adheres to the surface of the work 8 at the time of molding, and dust and fat also adhere to the surface of the work 8. The surface of the work 8 can be cleaned by ejecting the degreasing liquid. As the degreasing liquid, known alkaline degreasing liquids, organic solvents, surfactants and the like can be used, but potassium-phosphate-based liquids are particularly preferable. Since such a potassium / phosphate solution does not contain a surfactant, water can be repelled from the surface of the work 8. In this way, by suppressing the familiarity with water on the surface of the work 8, it is possible to prevent water from entering between the work 8 and the water-soluble film 3 in the hydraulic transfer device 20 described later. 8 Water-soluble film on the surface 3
Can be reliably attached.

Next, the work 8 is the dust removing and degreasing conveyor 5
7 transfers the degreasing chamber 51 from the degreasing chamber 51 to the first rinsing chamber 52, water is ejected from the nozzle 94 to the surface of the work 8 in the first rinsing chamber 52, and the degreasing liquid remaining on the surface of the work 8 is washed. After that, the work 8 is conveyed to the second water washing chamber 53, and water is similarly jetted from the nozzle 95 to the surface of the work 8.

After that, the work 8 is conveyed to the post-treatment chamber 54, and the post-treatment liquid such as an alcohol solvent is ejected from the nozzle 96 in the post-treatment chamber 54. The work 8 is further conveyed to the air blow chamber 55 by the dust removing and degreasing conveyor 57, and the surface of the work 8 is air blown in the air blow chamber 55, and the water droplets remaining on the surface of the work 8 are blown off. Since the inside of the processing chamber 56 is maintained at the positive pressure as described above, it is possible to prevent dust from entering the processing chamber 56.

Thereafter, the work 8 is transferred by the transfer robot 96 from the exit side of the dust removing and degreasing conveyor 57 to the common work transfer conveyor 40. Next, the work 8 is conveyed by the common work transfer conveyor 40 into the water-drying drying furnace 26, and the water droplets are completely removed in the water-drying drying furnace 26. Thereafter, the work 8 is conveyed from the opening 42 to the second floor shown in FIG. Next, the work 8 together with the pallet mounting jig is transferred by the transfer robot 97 from the common pallet of the common work transfer conveyor 40 to the entrance side of the two rows of the preliminary conveyors 24, 24. Further, the work 8 together with the pallet mounting jig is transferred from the outlet side of the preliminary conveyors 24, 24 onto the transfer chains 10 (see FIG. 6) of the two rows of hydraulic transfer devices 20, 20 by the transfer robots 98, 98. Reprinted.

In the hydraulic transfer device 20 shown in FIG. 6, the hydraulic transfer is performed on the work 8 placed on the transport chain 10 by the above-described operation. That is, the work 8 is immersed in the water 2 in the water tank 1 by the transfer chain 10. After that, the water-soluble film 3 having the print pattern 3a is attached to the surface of the pulled work 8. The work 8 having the water-soluble film 3 attached to the surface in this manner is then conveyed from the respective transfer chains 10 of the two rows of hydraulic transfer devices 20 through the connecting conveyor 27 into the degreasing chamber 21.

In the film removing device 21, hot water is sprayed onto the surface of the work 8 and the water-soluble film 3 attached to the surface of the work 8 is completely dissolved, leaving the print pattern 3a. In this way, the print pattern 3 is formed on the surface of the work 8.
Only a remains and the transfer is completed.

By the way, the work 8 before being introduced into the water pressure transfer device 20 is blown off by the air blow chamber 55 and is completely removed in the draining and drying oven 26. No water droplets remain between them and the transfer operation can be performed with high accuracy. That is, if water droplets remain on the surface of the work 8, the remaining portion (inorganic content) of the water drops will enter between the work 8 and the water-soluble film 3, and this inorganic content will form a convex portion on the print pattern 3a. There is. However, the print pattern 3a can be kept smooth by removing the water droplets.

Next, the work 8 is transferred from the downstream side of the film removing device 21 onto the common pallet of the common work transfer conveyor 40 by the transfer robot 100. The work 8 conveyed by the common work conveyer 40 then enters the water draining and drying furnace 24, and the water droplets of the warm water sprayed by the film removing device 21 are completely removed.

Thereafter, the work 8 is transported across the baking / drying oven 23 to the coating device 22 side by the common work transport conveyor 40. The work 8 reaching the coating device 22 is transferred from the common pallet of the common work transfer conveyor 40 to the coating pallet 36 (see FIG. 7) of the inlet conveyor 61 by the automatic transfer device 65 together with the pallet mounting jig.

The work 8 on the entrance conveyor 61 then enters into one of the coating booths 31a to 31d, depending on the shape of the work 8. That is, when the work 8 has, for example, four different shapes, the work 8 that has reached the automatic transfer device 65 is automatically transferred to the automatic transfer device 65.
At, the type of the work 8 is detected based on the pallet mounting jig for the work 8. Then, for example, when it is determined that the work 8 is a work to be coated by the coating booth 31a, the work 8 on the entrance conveyor 61 is, together with the coating pallet 36, the booth conveyor 63 for the coating booth 31a.
Transferred to a. Work 8 on booth conveyor 63a
Then enters the coating booth 31a, and the coating material is sprayed onto the work 8 from the tip of the arm 33a of the coating robot 32a. The work 8 whose surface is thus coated with the coating material is then conveyed from the booth conveyor 63 a to the exit conveyor 62 together with the coating pallet 36. After that, the work 8 is transferred from the coating pallet 36 of the exit conveyor 62 to the common pallet of the common work transfer conveyor 40 by the automatic transfer device 66 provided on the exit side of the exit conveyor 62.

For the work 8 having other shapes, the coating robot 32 is similarly installed in the other coating booths 31b to 31d.
The coating is applied by b to 32d. Thereafter, the work 8 is similarly transferred by the automatic transfer device 66 to the exit conveyor 62.
Are transferred from the coating pallet 36 to the common pallet of the common work transfer conveyor 40.

The work 8 is transferred by the automatic transfer device 66, and the empty coating pallet 36 is transferred to the connecting conveyor 64.
Then, it returns to the automatic transfer device 65 through the return conveyor 67. In the automatic transfer device 65, a new work 8 is placed on the paint pallet 36, and the above-described operation is repeated.

In the case of the present embodiment, the coating conveyor 60, which is composed of an inlet conveyor 61, an outlet conveyor 62, booth conveyors 63a to 63d, a connecting conveyor 64, and a return conveyor 67, is highly likely to be contaminated by paint. Since it is provided separately from 40, the common work transfer conveyor 40 can be kept clean. Therefore, it is possible to perform the dust removing and degreasing work, the hydraulic transfer work, the draining and drying work and the like on the work 8 in a clean state.

The work 8 transferred from the automatic transfer device 66 of the coating device 22 to the common work transfer device 40 is then heated in the baking / drying oven 23, and the paint on the surface of the work 8 is dried and hardened. .. Next, the work 8 is the baking and drying furnace 2
3 through the opening 43 to the first floor shown in FIG. After that, the work 8 is unloaded by the transfer robot 95a from the common work transfer device 40 at the unloading section 95, and is transferred from the unloading section 95 to the outside as a product.

On the other hand, the common work transfer device 40 with the work 8 unloaded returns to the side of the dust removing and degreasing device 50,
The above operation is repeated.

According to this embodiment, the dust removing and degreasing device 5
0, draining drying oven 26, water pressure transfer device 20, film removal device 2
1, draining drying oven 24, coating device 22, baking drying oven 23,
Since the unloading unit 95 and the unloading unit 95 are connected by the common work transfer conveyor 40, the work 8 can be continuously subjected to dust removal, degreasing work, hydraulic transfer work, and painting work. Therefore, it is possible to reduce the chances that dust adheres to the work 8 and perform the hydraulic transfer work and the painting work in a clean state on the work 8. Further, since the coating conveyor 60 in the coating device 22 which is easily soiled is provided separately from the common work transfer conveyor 40, the work on the common work transfer conveyor 40 is maintained while keeping the common work transfer conveyor 40 in a clean state. Various work can be performed. Therefore, the print pattern can be transferred and painted on the work 8 in a clean state.

Furthermore, by providing the second floor with the steps of hydraulic transfer, painting, baking and drying, which are particularly unfavorable to dust adhesion, and unloading, unloading, etc., which is relatively resistant to dust adhesion, to the outside of the factory. It is possible to reduce the influence of the mixing of dust that accompanies the movement of the work, the transferred work, and other materials.

Further, since the work 8, the pallet, the pallet mounting jig 115 and the like are supported above the common work transfer conveyor 40, even if dust generated due to abrasion of the conveyor 40 falls or scatters, the dust is Difficult to attach to the work.

[0049]

As described above, according to the present invention,
Since the dust removing and degreasing work, the hydraulic transfer work, and the painting work can be continuously performed on the work, it is possible to reduce the chance that the dust adheres to the work and keep the work in a clean state. Further, since the coating conveyor of the coating apparatus is provided separately from the common work transfer conveyor, various works can be performed on the work on the common work transfer conveyor while keeping the common work transfer conveyor in a clean state. Therefore, in a clean state, the print pattern can be transferred and painted on the work.
