  FIG. 4 is a perspective view showing a configuration of the peeling angle adjusting mechanism 46. FIG. 5 is a system diagram showing a schematic configuration of the transfer unit 3 and the peeling unit 4. The peeling angle adjusting mechanism 46 is a mechanism for adjusting the peeling angle α of the base material B with respect to the fabric R when the base material B is peeled from the transfer layer C transferred to the fabric R.

  The peeling angle adjusting mechanism 46 is configured to move the peeling roller 41 in the front-rear direction X parallel to the transport direction X1, and specifically, a pair of shafts that rotatably support the peeling roller 41 around its central axis. The bearing portions 461, a pair of guide rails 462 extending in the front-rear direction X, the bearing portions 461 are fixed, the pair of traveling members 463 traveling on the guide rails 462, and the traveling members 463 are synchronized with each other. It includes a pair of geared motors 464 that are driving sources for traveling in the direction, and a rack and pinion mechanism 465 that is a power transmission mechanism for transmitting the power of each geared motor 464. Each guide rail 462 is attached to a base 466, and the base 466 is fixed to a frame member 467 constituting a part of the machine body of the textile processing apparatus 100.

Therefore, the peeling angle α can be adjusted by moving the peeling roller 41 by the peeling angle adjusting mechanism 46.

  The peeling angle adjusting mechanism 46 is controlled by the peeling control unit 4A so that the peeling angle α becomes a predetermined angle. For example, when the type of the fiber material constituting the fabric R is cotton or silk, it is preferable to set the peeling angle α to 18 to 22 degrees (preferably 20 degrees). Moreover, when the kind of the fiber material which comprises the fabric R is polyester, it is preferable to set peeling angle (alpha) to 13-22 degrees (preferably 15 degrees). Moreover, when the kind of the fiber material which comprises the fabric R is nylon, it is preferable to set the peeling angle (alpha) to 8-12 degrees (preferably 10 degrees).

  As a result, the transfer layer C is transferred according to the type of fiber material constituting the fabric R, the type of dye and paste contained in the transfer layer C, and the environmental conditions such as temperature and humidity when the apparatus is in operation. Since the textile processing apparatus 100 can be operated after adjusting to an appropriate angle so that a part of the agent does not remain on the base material B, the transfer layer C in the laminate L after the pressure and heat treatment can be operated. Only the base material B can be reliably peeled off. Therefore, it is possible to prevent a part of the pattern from being lost in the printed fabric, and to improve the quality of the printed fabric.

One of the pair of bearings that pivotally support the squeeze roller 64 provided on the side is configured to be displaceable in the transport direction X1.

  That is, the transport roller 91 and the squeeze roller 64 are configured to be inclined with respect to the lateral direction Y. Therefore, by tilting the roller disposed immediately before the widening portion 95 and the auxiliary widening portion 94 with respect to the lateral direction Y, within the range where meandering is allowed in the widening portion 95 and the auxiliary widening portion 94. Thus, the fabric R can be conveyed. The displacement driving of the bearing in the transport direction X1 is controlled based on a signal from a meandering detection sensor that detects the position in the lateral direction Y of the fabric R provided near the roller.

  As shown in FIG. 2, the textile processing apparatus 100 includes an apparatus control unit 100A that controls the entire apparatus. The apparatus control unit 100A includes a CPU 101, a RAM 102, a ROM 103, and the like, and a fabric unwinding control unit 1A, a transfer paper unwinding control unit 2A, a transfer control unit 3A, a peeling control unit 4A, a steam heating control unit 5A, and a cleaning control unit 6A. , A drying control unit 7A, a fabric winding control unit 8A, a conveyance control unit 9A, a tentering control unit 96A, and the like are connected via a bus 110, and each of these control units is controlled to control the fabric R under predetermined processing conditions. The textile printing process is performed on

  The textile processing apparatus 100 is provided with an input unit 120. The input unit 120 is provided for the user to input parameters for specifying the fabric R and the transfer paper T, such as the type of fiber material constituting the fabric R and the components of the transfer layer C in the transfer paper T. . When parameters for specifying the fabric R and the transfer paper T are input by the user, the apparatus control unit 100A acquires the setting values of the respective processing conditions associated with the input parameters from the ROM 103, and the settings. The textile processing apparatus 100 is operated by controlling the control units 1A to 9A and 96A according to the values. In the ROM 103, optimum setting values for each processing condition are preset and stored in correspondence with parameters for specifying the fabric R and the transfer paper T.

  In the above, an apparatus for printing the fabric R by the dry transfer printing method, that is, a printing processing apparatus for transferring and printing the transfer paper T having the transfer layer C containing the dye on the cloth R and applying pressure and heat treatment. However, the present invention is not limited to this, and the apparatus for printing the fabric R by the dry sublimation transfer printing method, that is, the transfer paper T having the transfer layer C containing the dye is stacked on the fabric R and heat-treated. You may implement | achieve in the textile processing apparatus which prints.
