  In this example, the transcript cutting device 100 is provided in the transfer device 200 as shown in FIGS. 1 and 2.

  The transfer device 200 includes a transfer paper supply roller 211 that winds and supplies a transfer paper 210 on which a pattern such as a character is printed with sublimation ink, and a fabric supply roller 221 that supplies a transfer material 220 made of, for example, polyester. And a lower paper supply roller 231 for supplying the lower paper 230.

  In addition, the transfer device 200 includes a heater inside, and is disposed on the surface of the heating roller 240 and a heating roller 240 that heats the stacked body in which the transfer paper 210, the fabric 220, and the lower paper 230 are stacked. And an endless felt band 250 to be pressurized. The transfer device 200 includes a transfer paper roller 270 that winds up the transfer paper after transfer, a fabric roller 280 that winds up the cloth that has been transferred and cut, and a lower paper roller 290 that winds up the paper.

  In this example, the heating roller 240 and the felt belt 250 are arranged in the heating unit 201. The heating roller 240 is rotated by a motor (not shown) and is heated by a heater (not shown). In this example, the felt belt 250 is wound around the heating roller 240 by rollers 251 to 255. In this example, the roller 252 is moved up and down to adjust the position of the felt belt 250. In the vicinity of the roller 252, an upper limit switch 256 and a lower limit switch 257 for the felt position are provided. Further, the roller 225 includes a felt extension knob 258 that moves the roller 225 in accordance with the extension of the felt. In the figure, reference numeral 259 denotes a drive roller tension adjustment knob, and 260 denotes a felt position shift limit switch.

  In this example, the transfer paper roller 270, the fabric roller 280, and the lower paper roller 290 are arranged in the winding unit 202. In this example, the transfer paper roller 270, the fabric roller 280, and the lower paper roller 290 are synchronously rotated by the motor 310. Sprockets 311, 312, and 313 are attached to the rollers 270, 280, and 290, and a roller chain 315 is wound around the rollers. Reference numeral 314 indicates a sprocket for turning the roller chain 315.

  In this example, the cutting device 100 is attached to a rectangular pipe-shaped beam member 203 that is passed in the width direction of the heating unit 201 as shown in FIGS. 1 to 3. As shown in FIG. 3, the cutting device 100 covers the beam member 203, and has a square pipe-shaped mounting portion 102 that is movably disposed along the beam member 203, and stands downward from the mounting portion 102. The flange parts 103 and 104 to be provided and the feed screw 105 arranged between the flange parts 103 and 104 are provided. Note that a handle 121 is disposed on the attachment portion 102, and the attachment portion 102 can be fixed to the beam member 203. Note that the movement of 102 can be performed manually or automatically by means such as a feed screw. In the figure, reference numerals 204 and 205 denote shafts, 206 denotes an insertion table, and 207 denotes an insertion roller driven by an air cylinder. Reference numerals 131 and 132 in the figure indicate slide bushes that engage with the shafts 204 and 205.

  In this example, the moving screw 106 is disposed on the feed screw 105, the shaft 113 is disposed on the moving table 106, and the blade mounting base 107 is rotated on the shaft 113 with respect to the shaft 113. It is arranged to be movable. In this example, the blade mounting base 107 is rotationally driven with respect to the shaft 113 by a push rod 108a and a spring (not shown) of the air cylinder 108, and can take two inclined states: a cloth cutting state and a retracted state. .

  In the cloth cutting state, the blade mounting base 107 is disposed at a position where a blade edge 111 (to be described later) cuts the cloth 10, and the blade edge is pressed against the blade receiving shaft 204 that guides the cloth 10 with an appropriate force. In the retracted state, the cutting edge 111 is separated from the fabric 10.

In this example, the position of the blade mounting base 107 is adjusted by rotating the feed screw 106 with a handle 114. The driving of 106 can be automatically performed by a pulse motor or the like. In FIG. 1, reference numeral 122 denotes a cut position adjustment knob, and 123 denotes a fabric adjustment knob.

  Further, a blade mounting portion 109 is disposed on the blade mounting base 107 so that its mounting angle is variable. In this example, 107 is fixed to the blade mounting portion 109 by sandwiching the blade mounting portion 109 between the two protruding flange portions 109a and 109b.

  A cutting blade 110 is disposed at the tip of the blade mounting portion 109. In the present example, the cutting blade portion 110 is disposed so as to come into contact with the blade receiving shaft 204 spanned over the winding portion 202 in the cloth cutting state. The cutting blade portion 110 is formed with a sharp blade edge portion 111, and an electric heater 112 is disposed therein as a heating means. In this example, since the fabric 10 to be cut is made of polyester, by keeping the blade edge portion 111 at a high temperature, the fabric 10 is melted and cut easily, and the cut end of the fabric 10 is welded to prevent fraying. .

  In this example, four cutting devices 100 are arranged as shown in FIGS. By arranging four in this way, the two transfer portions 11 and 12 that are simultaneously transferred onto one piece of fabric 10 can be separated in the longitudinal direction. At this time, as shown in FIGS. 5 and 6, the arrangement position of the blade edge portion 111 may be set so that the cutting lines 13, 14, 15 and 16 are arranged inside the transfer portions 11 and 12. desirable.

  Note that the number of cutting devices arranged is not limited to the above example, and only one or five or more cutting devices may be provided. FIG. 7 shows a case where six cutting devices 100 are provided. Of course, this example can be applied even when the widths w1, w2, and w3 of the transfer portions arranged in parallel are different. In addition, the cut | disconnection of the short length direction of the fabric cut | disconnected by the longitudinal direction can be performed manually or another automatic apparatus.

  FIG. 8 shows another embodiment of the present invention. In this example, sensors 401, 402, 403, and 404 (for example, optical sensors) that detect the contours of the transfer units 11 and 12 are arranged downstream of the heating roller 240 of the transfer device 200, and the sensors 401, 402, 403, and 404 are arranged. Is provided with blade position control means 405 for adjusting the position of the blade edge portion 111 by drivingly controlling the cutting device 100 based on the output of the above. The blade position control means 405 automatically moves the position of the blade edge portion 11 by driving blade edge moving means 406, 407, 408, 409 in which a step motor or the like is mounted on the feed screw 105.

  According to this example, accurate cutting can be performed even with respect to the positional fluctuation of the transfer portions 11 and 12. In addition, a CCD line sensor or the like that uses the entire width of the fabric as a detection width is used as the optical sensor, and the number of transfer portions and the transfer width of the entire fabric are accurately recognized, and the fabric is cut with the recognized number and width. So that the cutting device can be moved. In this way, it is possible to automatically perform cutting with an appropriate width without adjusting the position of the cutting device each time for fabrics having transfer widths that are not equally spaced or for transfer operations in which the transfer width changes. .
