Problems solved by technology

[0014] However, these methods are mainly used for film recovery and residue recovery on the surface of the transfer liquid (water surface), and are not only large-scale in terms of structure, but also are intermittent processing methods that perform film recovery and residue recovery every transfer. , therefore, it also takes time, and the efficiency is poor, so it cannot be called an ideal method

Embodiment 1

[0402] The present invention takes the above-mentioned embodiment as a basic technical idea, but the following changes can also be considered.

[0403] First of all, in the above-mentioned embodiment, the impurities in the transfer liquid L are efficiently recovered mainly by using the two-stage OF structure, and the cleaning of the liquid outlet area P2 is realized, but when the cleaning of the liquid outlet area P2 (transfer liquid L In the process of cleaning), it is not necessary to have a two-stage OF structure, and it may be as follows (this will be referred to as "other example 1").

[0404] That is, as an example Figure 24 ~ Figure 26As shown, this method (other embodiment 1) is provided with a new water supply port 107 below the overflow tank 92 used for forming the flow away from the appearance surface, and supplies new water upwards from here toward the liquid outlet area P2 (in other embodiments 1, the reference symbol "PU" is attached to the fresh water), and th...

Embodiment 2

[0417] In addition, in the above-mentioned basic embodiment, the mode in which the active agent is coated on the transfer film F and then supplied to the transfer tank 2 is mainly shown (refer to figure 1 ), but the activation of the transfer film F as described above can also be carried out in the state of being supplied to the transfer tank 2 and in contact with the liquid. In this case, there is a preferred activation form corresponding to this. Therefore, This will be described below (this will be referred to as "other example 2"). That is, in other Example 2, the active agent application device (apparatus assigned reference numeral "4" in the basic embodiment) is changed so that the transfer film F supplied to the surface of the transfer liquid L of the transfer tank In the activated form, in particular, the reference numeral "active agent application device 40" is attached to the device to distinguish it from the basic embodiment. In addition, by the way, here, the hyd...

Embodiment 2

[0482] Embodiment (other embodiment 2: Figure 28 )

[0483] On the other hand, in the present system in which the drain water after mold release cleaning is supplied to the transfer tank 20, the mold release cleaning device 90 implements hot water spray 902 using two storage tanks 904 and a circulation pump and a flow rate of 20 L / min. Rinse water spray 903, import 15L / min release water (refer to Figure 28 ). The PVA concentration of the mold release water was 600 ppm after 3 hours and 1200 ppm after 8 hours.

[0484] The initial PVA concentration of the transfer tank 20 was adjusted to 500ppm, and the above-mentioned release water was introduced and the transfer process was continued. As a result, the PVA concentration of the transfer water after 8 hours was 1350ppm, 1700ppm after 16 hours, and 800ppm after 80 hours. 2000ppm, and 2040ppm after 160 hours, the transfer film characteristics were stable, and no defect caused by the transfer film F was found.

Abstract

It is an object to develop a novel liquid pressure transferring technique for not allowing film residuals, foam, and the like on a transfer liquid surface to approach a design surface of an object floating up from the transfer liquid with a relatively simple structure. The present invention relates to a liquid pressure transferring technique for forming an appropriate transfer pattern on the surface of an object by pressing the object from the upper side of a transfer tank, in a liquid-leaving area in which the object is pulled up from the transfer liquid in the transfer tank, a design surface oppositely-separating flow that is separated away from a design surface of the object that is in the process of getting out of a liquid is formed by using the design surface cleaning device such as an overflow tank, and foam on a surface of the transfer liquid and foreign substances staying in the liquid are separated away from the design surface of the object that is in the process of getting out of the liquid and are discharged outside the transfer tank.

Description

technical field [0001] The present invention relates to a hydraulic transfer printing, which floats and supports a transfer film formed by pre-applying an appropriate transfer pattern (surface ink layer) with transfer ink on the liquid surface, and pushes the object to be transferred on the transfer film On the film, while submerging the transferred body into the transfer liquid, the transfer pattern on the film is transferred to the transferred body by using its hydraulic pressure, especially involving a novel hydraulic transfer method, This prevents film residues, foam, etc. on the surface of the transfer liquid from leaning against the appearance surface of the object to be transferred that floats up from the transfer liquid. Background technique [0002] Hydraulic transfer is known as follows: a transfer film obtained by applying a water-insoluble appropriate transfer pattern on a water-soluble film (carrier sheet) in advance is floated in a transfer tank (transfer liqui...
