 Conventionally, as shown in FIG. 4, a synthetic resin panel 50 used for a vanity has a concave portion 50a into which a mirror is fitted by using a vacuum forming machine from one sheet, and a convex portion on which a small article is placed. It was formed into a shape such as 50b. This manufacturing process was automated or semi-automated, and if a synthetic resin sheet was placed at the beginning of this manufacturing process, the specified product could be produced after the manufacturing process. Therefore, it is necessary to attach the sheet or semi-finished panel to each device in the manufacturing process, and the outer peripheral portion 50c is required for the guide, but after the panel is completed, the outer peripheral portion 50c becomes unnecessary. It was cut off by a cutter device 60 as shown in FIG.

In FIG. 5, a cutter device 60 is mounted on a table 61, and a main body 63 is moved by a cylinder 64 along a rail 62 laid on the table. A rotatable arm 65 is attached to the main body 63, and a cutter portion 66 is attached to the tip of the arm 65 so as to be vertically movable. Further, a rotary turntable 67 is mounted on the table 61, and the panel 50 is placed on the turntable 67, and an unnecessary outer peripheral portion 50c is cut by the cutter portion 66 because it is not rotated. These operations are controlled by a relay by setting each switch 69a of the control box 69, and the panel 50 is placed on the turntable 67 from the right side of the cutter device 60 by a carrier not shown and turned off. Cutting work is performed, and after cutting is taken out to the left.

[Problems to be solved by the device]

 However, in the conventional cutter device 60, since there is no dust-proof cover or the like around the cutter device 60, there is a problem that chips of the molded product are generated and scattered around when the panel 50 is cut. Therefore, there is a problem in that the cutter device 60 enters a movable part, for example, the rail 62 or the cylinder 63, and causes a failure, which requires maintenance work. In addition, there is a problem that a dust mask is necessary for the health of the observer of the cutter device 60 or a person who works in the vicinity due to the generation of chips. Further, since the cutter portion 66 of the cutter device 60 is integral with the motor, it is heavy, and since the cutter portion 66 is attached to the tip of the arm 65 and moves, the balance is poor and it is difficult to carry out precise operation. There was a problem that it was easily worn. Further, since the rotary blade of the cutter portion 66 is located on the outer peripheral portion, there is a problem in work safety. Further, the control of the cutter device 60 is performed by the relay, which delays the cycle time of the work, and there is a problem that the fine control cannot be performed. Therefore, the present invention has been made in view of the above circumstances, and provides a cutter device in which chips of a molded product do not scatter to the outside, is safe in operation, and can be finely controlled with less maintenance. is there.
