The support 34 is configured to be movable in the upstream / downstream direction of the water tank 2 and in the vertical direction with respect to the water tank 2 by a moving unit (not shown), and is usually located outside the water tank 2.

Next, a hydraulic transfer method using the hydraulic transfer device 1 having the above-described configuration will be described with reference to FIGS.
First, the inside of the bathtub 5 is masked with a masking tape except for the ear part 5a and the inner surface upper part 5b that transfer the ink film 3b of the transfer film 3 to the bathtub 5 (see FIG. 1A).

  Then, in the feeding mechanism 4 provided at the upstream end 2 b of the water tank 2, the transfer table 13 is horizontally fed onto the water tank 2, and at the same time, the transfer film wound around the feeding roll 11 by the gripper 12 on the upper side of the transfer table 13. Roll out 3. Therefore, the gripper 12 and the transfer film 3 fed out by the transfer table 13 are fed out on the water surface of the water tank 2 while being mounted in a non-contact manner on the water surface of the water tank 2 and travel downstream (FIG. 6A). reference).

  Next, when the transfer film 3 is drawn out on the water surface of the water tank 2 by a predetermined length, the portion of the transfer film 3 sandwiched between the feed roller and the transfer table 13 on the upstream end 2b side is cut by a cutter (not shown). In this state, the transfer film in the water tank 2 is placed on the transfer table 13, and the push rod 15 is positioned slightly upstream from the gripper 12. Then, the transfer table 13 is slightly retracted while pushing the transfer film 3 at the tip end portion near the gripper 12 with the push rod 15. Then, the center of the front-end | tip part of the transfer film 3 pressed with the push rod 15 is pressed against the water surface (refer FIG.6 (b)).

  Then, when the transfer table 13 is sequentially retracted to the upstream side, the transfer film 3 whose tip is immersed in the water surface descends sequentially and contacts the water surface (see FIG. 6C). At this time, the contact area of the transfer film 3 with the water surface is gradually increased from the center of the front end portion that is pressed by the push rod 15 to contact the water surface toward the upstream side of the water surface. Then, when the gripper 12 is separated from the transfer film 3, the transfer film 3 is placed on the same plane as the water surface without involving air. Then, the gripper 12 and the push rod 15 are retracted upstream.

  The transfer film 3 has an ink film 3b on the upper side and a film 3a such as PVA on the lower side. If wrinkles remain on the transfer film 3, the wrinkles are lengthened by pricking them by hand. Moreover, the film 3a starts to melt | dissolve in water gradually by contacting water. Next, the activator is sprayed on the entire surface of the ink film 3b of the transfer film 3 by the spray nozzle 18 while moving the support portion 16 from the upstream side to the downstream side along both side portions of the water tank 2 (FIG. 6D). reference). Here, by retracting the traveling platform 12A shown in FIG. 3 upstream, the gripper 12 and the push rod 15 are protected by the traveling platform 12A, and the activator is prevented from adhering to the gripper 12 and the push rod 15. To do.

  1, the bathtub 5 is held upside down by the vacuum pads 24 of the four arms 23a, 23a, 23b, and 23b of the elevating means 6, and the transfer film 3 in the water tank 2 is moved. Position it above. In this state, the elevating unit 22 is lowered in a direction substantially orthogonal to the water surface. On the surface of the water, it is lowered at a high speed to about 20 to 40 mm, and thereafter lowered at a very low speed (for example, 5 to 30 mm / min) to enter the water. Then, as shown to Fig.7 (a), the ear | edge part 5a part of the bathtub 5 is pressed against the transfer film 3, and it penetrates under the water surface, transferring the ink membrane | film | coat 3b. At this time, the film 3a made of PVA of the transfer film 3 is dissolved in water, and a part of the undissolved portion adheres to the bathtub 5 together with the ink film 3b. In addition, the ink film 3b is divided in the outer region of the transfer portion to the bathtub 5, and becomes a transfer tub or floats or sinks on the water surface. The ink film 3b located inside the bathtub 5 is transferred to the mask.

  When the transfer of the ink film 3b to the ear 5a and the inner surface upper part 5b of the bathtub 5 is completed, the elevating unit 22 is raised and the bathtub 5 is pulled up. Then, the support body 34 is moved to the downstream end 2a of the water tank 2 by the moving unit described above, and is submerged in water. At this time, the upper end of the receiving basket 32 is allowed to sink so as to be located above the water surface of the water tank 2. Then, the partition plate 7 is moved from the upstream side to the downstream side of the water tank and stopped at the stop position on the downstream side, so that the transfer basket and the residue floating below the water surface and the water surface are pushed to the downstream side, and the receiving basket 32 It is made to adhere to the nonwoven fabric arrange | positioned on the inner surface (refer FIG.7 (b)). At this time, a part of the transfer wrinkles or residues adheres to the partition plate 7 due to its adhesiveness.

  Next, with the rotating brush 31 rotated, the support 34 is moved to the upstream side of the water tank 2 by the moving unit, and the rotating brush 31 is brought into contact with the partition plate 7 with an appropriate pressure. The rotary brush 31 scrapes off the transfer soot and residue remaining on the partition plate 7, and the nozzle 33 sprays high-pressure water toward the rotary brush 31 so that the transfer soot attached to the rotary brush 31 from the partition plate 7. And stripping off and removing residues. At this time, the scraped or peeled transfer residue or residue is deposited on the nonwoven fabric disposed on the inner surface of the receiving basket 32 (see FIG. 7C).

Thereafter, the rotation of the rotating brush 31 is stopped, and the recovery means 8 is moved out of the water tank 2 by moving the support 34 to the downstream side of the water tank and raising it by the moving unit. Then, the non-woven fabric placed on the inner surface of the receiving basket 32 is taken out and discarded together with the attached transfer tub, residue, etc., and a new non-woven fabric is received and placed on the inner surface of the basket 32. Further, the partition plate 7 is moved to a predetermined position on the upstream side of the water tank 2 by the chain 25.
The bathtub 5 pulled up by the elevating unit 22 is conveyed to the next process, and the wrinkles and the like of the film 3a are removed in the cleaning process, dried, and top coated to be glossy.
And the same process is repeated about the next bathtub 5, and the ink membrane | film | coat 3b is transcribe | transferred.

  According to the hydraulic transfer device 1 configured as described above, the transfer scum or the like adhering to the partition plate 7 is scraped off by the rotating brush 31 and collected by the receiving basket 32 so that the transfer slag or the like is discharged out of the water tank 2. Therefore, it is possible to avoid deteriorating the water quality in the water tank 2 and to improve and stabilize the transfer quality of the bathtub 5 that is a transfer target. In addition, when the transfer brush or the like attached to the partition plate 7 is scraped off by the rotary brush 31, when the transfer stick or the like is attached to the rotary brush 31, high pressure water is jetted from the nozzle 33 toward the rotary brush 31. The transfer stick or the like attached to the rotating brush 31 can be peeled off and collected by the basket 32.

Here, the burden on the above-described filter that connects the sub-tank 9 and the water tank 2 can be reduced by not discharging the transfer soot and the like adhering to the partition plate 7 to the sub-tank 9.
Further, by disposing the non-woven fabric on the inner surface of the receiving basket 32, the transfer bag or the like does not adhere to the receiving basket 32 but adheres to the non-woven fabric. By exchanging this non-woven fabric, the transfer bag or the like can be easily collected. Become.

In addition, this invention is not limited to the said Example, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, in the above embodiment, a bathtub is used as the transfer object. However, the transfer object of the present invention is not limited to such an article, and various large household appliances such as refrigerators, washing machines, and air conditioners are used. It can be applied to various large items such as doors, main bodies, automobile doors and bonnets. Furthermore, the present invention can be applied to small articles such as a casing of a mobile phone.
Moreover, in the said Example, the structure which injects high-pressure air in which the nozzle is comprised so that high pressure water may be injected with respect to a rotating brush may be sufficient.
Moreover, although the nonwoven fabric is arrange | positioned on the inner surface of a receiving basket, you may use other disposable filters. Moreover, the nonwoven fabric may not be arranged. At this time, since the transfer basket or the like adheres to the receiving basket, the attached transfer basket or the like can be easily peeled off by lifting the receiving basket from the water tank and then separately washing it with high-pressure water or the like.
