The conveyor 5 has a conveyor belt 19 arranged horizontally and transfers the plastic molded sheet 1 horizontally. Ordinary conveyors carry goods on a belt. The conveyor 5 of the cutting device of the present invention adsorbs and transfers the plastic molded sheet 1 to the lower surface of the conveyor belt 19. The plastic molded sheet 1 is adsorbed on the lower surface of the conveyor belt 19 by air pressure. In the conveyor 5 of FIG. 3, a plurality of rows of conveyor belts 19 are arranged in parallel so that air can pass between the conveyor belts 19. The multiple rows of conveyor belts 19 move together,

The conveyor 5 having a plurality of conveyor belts 19 arranged in parallel has a structure capable of adjusting the interval between the conveyor belts 19 and can transfer the plastic molded sheet 1 forming molded articles of various shapes. . This is because the position of the conveyor belt 19 can be moved between the protrusions protruding on the upper surface. The plastic molded sheet 1 is not always the same molded product. The conveyor 5 transfers the plastic molded sheets 1 having different shapes and sizes of molded products from the supply mechanism 2 to the cutting machine 3.
When the shape of the molded product is different and the position of the convex portion protruding on the upper surface changes, it is necessary to dispose the conveyor belt at a position where the conveyor belt does not collide with the convex portion, that is, between the convex portions. For this reason, the conveyor for transferring the plastic molded sheets having different shapes of molded products has a structure in which the interval between the conveyor belts can be adjusted.

However, a net conveyor can also be used as the conveyor. The net conveyor uses a conveyor belt as a net material, and the conveyor belt itself can pass air. Therefore, this conveyor can suck air from the upper side and adsorb the plastic molded sheet on the lower surface.

The fan 6 is arranged above the conveyor 5 and sucks the plastic molded sheet 1 onto the lower surface of the conveyor 5. The fan 6 is a pressure fan that is rotated by a motor, and blows air from the bottom to the top in the drawing to adsorb the plastic molded sheet 1 to the lower surface of the conveyor belt 19. The fan 6 is provided with a duct 20 on the suction side so that the air on the suction side can effectively pass through the conveyor 5.
The fan 6 is constantly rotated to adsorb the plastic molded sheet 1 on the lower surface of the conveyor 5. The transfer mechanism 4 in the figure is
A plurality of fans 6 are arranged along the conveyor 5. The fan 6 having this structure has a feature that it can surely adsorb the plastic molded sheet 1 transferred by the conveyor 5.

The loader 7 supplies the plastic molded sheet 1 of the supply mechanism 2 to the lower surface of the conveyor 5. The loader 7 includes a suction cup 9 that sucks the upper surface of the plastic molded sheet 1, a suction machine 21 that sucks air from the suction cup 9,
And a vertical stroke mechanism 22 for moving the suction cup 9 up and down. The suction cup 9 adsorbs the plastic molded sheet 1 and lifts it in a horizontal posture. In the illustrated apparatus, a plurality of suction cups 9 are arranged between the conveyor belts 19 to adsorb the upper surface of the plastic molded sheet 1. The plurality of suckers 9 are
Adsorb the upper surface of the plastic molded sheet 1 in a well-balanced manner and raise it.

The suction cup 9 is formed by molding a rubber-like elastic body into a cup shape having a downward opening, and has a central hole having an airtight structure and a suction device 21.
Connected to. The suction cup 9 shown in the figure is a vertical stroke mechanism 2
2 is connected to the lower end of the vertical rod 23,
Is connected to the suction device 21. The up-and-down stroke mechanism 22 includes a vertical rod 23 and an up-and-down base 24 connecting the upper ends of the vertical rods 23. Upper and lower stand 24
Is vertically reciprocated vertically through a guide 25 and a cylinder 26. The lowering position of the upper and lower table 24 is a position where the suction cup 9 can adsorb the plastic molding sheet 1 of the supply mechanism 2, and the raising position can supply the plastic molding sheet 1 adsorbed by the suction disc 9 to the lower surface of the conveyor 5. The position, that is, the lower surface of the conveyor 5 or above it. When the suction cup 9 is moved above the conveyor 5, the suction cup 9 is attracted by the plastic molded sheet 1
Away from the surface of. This is because the rise of the plastic molded sheet 1 is stopped by the conveyor belt 19 and the suction cup 9 separates from the plastic molded sheet 1.

The loader 7 having this structure includes the vertical rod 23.
And the plastic molded sheet 1 on the supply table 10 is sucked by the suction cup 9, and then the vertical rod 23 is raised to supply the plastic molded sheet 1 to the lower surface of the conveyor 5.

The plastic molded sheet 1 supplied to the conveyor 5 by the loader 7 is transferred to the cutting machine 3 by the conveyor 5, and then separated from the conveyor 5 by the take-out mechanism 8 and transferred to the cutting machine 3. The take-out mechanism 8 moves the suction cup 9 up and down like the loader 7, and supplies the plastic molded sheet 1 from the conveyor 5 to the cutting machine 3. The suction cup 9 of the take-out mechanism 8 descends from the lower surface of the conveyor 5 or above it to adsorb the upper surface of the plastic molded sheet 1, and further descends to supply the plastic molded sheet 1 to the cutting machine 3. The mechanism for moving the suction cup 9 up and down can be the same mechanism as the loader 7.

The cutting device having the above structure transfers the plastic molded sheet 1 from the supply mechanism 2 to the cutting machine 3 in the following steps. A plurality of plastic molded sheets 1 are supplied from a molding machine. The plastic molded sheet 1 is stacked and supplied to the supply mechanism 2. At this time, the suction cup 9 of the loader 7 is in the raised position. The suction cup 9 of the loader 7 descends and the plastic molded sheet 1
Adsorb the upper surface of. The suction cups 9 adsorb a plurality of locations of the plastic molded sheet 1 in a well-balanced manner and allow the plastic molded sheet 1 to rise horizontally. Since the plastic molded sheet 1 has a flat space between molded products, this portion is sucked by the suction cup 9. The suction cup 9 of the loader 7 rises and supplies the plastic molded sheet 1 to the lower surface of the conveyor 5. The supplied plastic molded sheet 1 is adsorbed on the lower surface of the conveyor 5 by the fan 6. Since the fan 6 operates continuously, the conveyor 5
The plastic molded sheet 1 supplied to the lower surface of the is adsorbed by air pressure. Since the conveyor 5 is also operating continuously, the supplied plastic molded sheet 1 is transferred toward the cutting machine 3. The plastic molded sheet 1 transferred above the cutting machine 3 collides with a stopper (not shown) provided in the transfer path and is stopped at a fixed position. At this time, the suction cup 9 of the take-out mechanism 8 is at the raised position and does not disturb the transfer of the plastic molded sheet 1.
The suction cup 9 of the take-out mechanism 8 descends, and the plastic molded sheet 1 is transferred from the conveyor 5 to the cutting machine 3. After the plastic molded sheet 1 is adsorbed by the cutting machine 3, the suction cup 9
The on-off valve 27 that is connected between the suction cup 21 and the suction device 21 is closed to release the state where the suction cup 9 sucks the plastic molded sheet 1. The on-off valve 27 is opened when the suction cup 9 adsorbs the plastic molded sheet 1, and is closed when releasing the adsorption. Extraction mechanism 8 whose suction state has been released
The suction cup 9 moves to above the conveyor 5. The plastic molded sheet 1 adsorbed by the cutting machine 3 is cut around the molded product by the cutting machine 3.

After that, the steps 1 to 3 are repeated to transfer the plastic molded sheet 1 to the cutting machine 3 and cut the peripheral edge of the molded product.
