(Workpiece setting method)
A method for setting a workpiece in the cutting apparatus according to this embodiment will be described with reference to FIGS. FIG. 6 is a diagram illustrating a set state of the conveyance mechanism of the cutting device according to the present embodiment, and FIG. 7 is a diagram illustrating a state where the roller pressing force is released from the set state of the conveyance mechanism of the cutting device according to the present embodiment. FIG. 8 is a view showing an open state of the transport mechanism of the cutting apparatus of the present embodiment.

  In the set state of FIG. 6, the lever 79 is fixed at the position of the arrow on the set seal 7. In this set state, the release bar 62 is operated by the lever 79, and the release angle bearings 60a and 60b push up the arms 68a and 68b via the release angles 57a and 57b and the release arm shafts 58a and 58b. As a result, the roller arms 51a and 51b are pulled up and rotated clockwise through the springs 75a and 75b, the stoppers 71a and 72b, the shafts 72a and 72b, the screws 73a and 73b, and the stud pins 76a and 76b, and the rubber rollers 47 is pressurized.

  In this set state, the workpiece 32 is conveyed with the workpiece 32 sandwiched between the rubber roller 40 and the rubber roller 47 with an appropriate pressure.

  Next, as shown in FIG. 7, when the lever 79 is rotated about 90 degrees clockwise from the set state around the release bar 62, the release bar 62 is operated by the lever 79, and the release bar 62 is operated. The release angle bearings 60a and 60b are retracted from the arms 68a and 68b via the angles 57a and 57b and the release arm shafts 58a and 58b. As a result, the arms 68a and 68b are lowered, and the pressure applied to the rubber roller 47 via the springs 75a and 75b, the stoppers 71a and 71b, the shafts 72a and 72b, the screws 73a and 73b, and the stud pins 76a and 76b is released.

  In this intermediate state, the rubber roller 47 is only in contact with the rubber roller 40 by its own weight and is not pressurized.

  Next, as shown in FIG. 8, when the lever 79 is further rotated clockwise around the release bar 62 and reaches the position of the arrow of the set seal 7, the release bar 62 is moved by the lever 79. When operated, the release angle bearings 61a and 61b rotate the roller arms 51a and 51b about the roller arm shaft 52 about 30 degrees counterclockwise through the release angles 58a and 58b and the release arm shafts 59a and 59b. Let Thereby, the rubber roller 47 rotatably supported by the roller arms 51a and 51b moves upward, and the space between the pair of rubber rollers 40 and the rubber roller 47 is opened.

  When the workpiece 32 is set in the cutting apparatus of this embodiment, the lever 79 is operated to change the set state of FIG. 6 to the open state of FIG. 8 through the intermediate state of FIG. The pair of rubber rollers 40 and 47 can be opened without requiring extra force such as resisting the applied pressure.

  In the open state of FIG. 8, the workpiece 32 is set, the position thereof is determined, and the lever 79 is operated to change the open state of FIG. 8 to the intermediate state of FIG. 7 by the pair of rubber rollers 40 and 47. The workpiece 32 is sandwiched. In the intermediate state shown in FIG. 7, no pressure is applied to the rubber rollers 40 and 47, so that the position of the workpiece 32 can be finely adjusted by slightly operating the lever 79.

  When the position of the workpiece 32 is determined, the lever 79 is operated to change the intermediate state of FIG. 7 to the set state of FIG. 6, and the workpiece 32 is sandwiched between the pair of rubber rollers 40 and 47 with an appropriate pressure. Then, the setting of the workpiece 32 is completed.

  Thus, according to this embodiment, it is possible to release the applied pressure of the pair of rubber rollers that sandwich the workpiece and release the applied pressure of the pair of rubber rollers by simply operating the lever. It is possible to easily replace and load the workpiece.
