Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves molding a resin sheet using a molding device, and then punching out the molded portion using a trimming device consisting of a die and a punch and discharging the squeeze-molded products, such as plates and cups, downward from the die. They are stacked in order on a support lifting shaft that moves down at the same time.
In response to a predetermined number of stacking completion signals, the support lifting shaft is rapidly lowered together with a constant number of stacked molded products, and the pusher reciprocates to eject them from the bottom surface of the die to the side, after which the lifting shaft is raised at high speed and punched out. In a known device that moves back to the punching position of the molded product, from the completion of stacking the predetermined number of molded products to the lifting of the support lift shaft, a temporary support plate is advanced to the lower surface of the die, and the punch is punched out by a punchless stop operation. Several punched products are received in a stack, and when the number becomes constant, the supporting lifting shaft is rapidly lowered, and in the middle of the process, only the punched products are left on the base plate and pushed out by the reciprocating action of the pusher. Later, the support lifting shaft is quickly raised, and as the support lifting shaft is raised rapidly, the temporary support plate is retracted and several punched products are transferred onto the support shaft, and the several punched products are moved onto the support shaft. This relates to a processing device for resin sheet punched molded products that restarts stacking up to a predetermined number of resin sheet punched molded products including It not only simplifies post-processing such as packaging by taking out stacked blocks at the destination, but also automatically forms stacked blocks by stacking a predetermined number of punched products without stopping the punching operation. To provide a processing device which can be taken out at any time.

An embodiment of the invention will be described with reference to the accompanying drawings.

In Figures 1 to 3, 1 is a die of a trimming device, and 2 is a punch that moves intangibly between the retracted position above the die 1 and the punching position where it fits into the die 1 with a constant stroke and timing. On the die 1, squeeze molded portions b such as plates and cups formed by a molding device on a continuous resin sheet a are sequentially supplied each time the punch 2 moves to the retracted position. The punched product c is dropped into the die 1 with the downward punching force.

Reference numeral 3 denotes a support lift shaft provided below the center of the die 1, and the support head 4 at the upper end is fitted into the squeeze-formed portion of the punched product c from below.

Reference numeral 5 denotes a support plate for the stacked product, and is provided with a through hole 6 through which the support lifting shaft 3 and the support head 4 can freely enter and exit.

A busher 7 stands by at the side of the through hole 6 on the support plate 5, is attached to the piston rod 9 of the first cylinder 8, and reciprocates as the rod 9 expands and contracts.

Reference numeral 10 denotes a temporary support plate which retreats to the lower side of the die 1 and waits, and is fixed to the second cylinder 11 and the piston rod 12 and closes the lower opening of the die Y as the rod 12 expands.

13 is a switch for generating a count signal with a contact actuation lever 14 facing the movement range of the punch 2, and 15 is an electromagnetic counter to which an arbitrary set number can be set.

The switch 13 generates a pulse count signal and sends it to the counter Kl5 every time the punch 2 punches the punched product c by descending, and the counter 15 generates a count-up signal using a fixed number of count signals. It returns to zero after it occurs. The support lifting shaft 3 is attached to the lower opening of the die 1 as shown in FIG. The support head 4 is raised at high speed to a height that supports the three to five stacked punched products c by the temporary support plate 10 that has advanced into the cage and closed the lower opening, and then A predetermined number of punched products C. A count-up signal from the counter 15 generated at the same time as the stack of When it advances to the chain line position and immediately returns to the solid line position, the return is confirmed at the same time and the machine moves to the above-mentioned high-speed ascent.

Further, when the support lifting shaft 3 starts to rapidly descend and the uppermost layer of a predetermined number of molded products c stacked on the support head 4 exits from the lower opening of the die 1, the temporary support plate 10 alternately moves the die 1 as shown in FIG. Proceed to the lower opening of. Further, as shown in FIG. 3, the support elevating shaft 3 rapidly rises and approaches the lower surface of the temporary support plate 10, and at the same time, as shown in FIG. 1, it is retracted. Therefore, the number of times that the punch 2 is lowered while the temporary support plate 10 is opening the lower opening of the die 1 is a fixed number of times in the range of three to five times, and the number of times that the punch 2 is lowered is within the range of three to five times. A certain number of punched products c are stacked on the temporary support plate 10 as shown in FIG. In this embodiment, at the same time that a predetermined number of punched products c overlap to form one block, the support lifting shaft 3 and the support head 4 rapidly descend as shown in FIG. 2, and the block of punched products c becomes transparent. It is supported by the support plate 5 around the hole 6, and is pushed out from below to the side of the die 1 by the subsequent advancement of the busher 7, and as the busher 7 returns to the solid line position, the support lifting shaft 3 and the support head 4 rises rapidly.

As shown in FIG.
If the temporary support plate 10 is retracted at the same time as the support head 4 passes through the groove 10a as shown in the figure,
Alternative support of several punched products c on the temporary support plate 10 of FIG. 3 can be made even smoother.

As clarified from the above description, the present invention supports the punched products c that are processed in large quantities at extremely high speeds in a stacked manner at the upper end of the support lifting shaft 3, and the height of the stack of the lifting shaft 3 is A fixed number of punched products are stacked up by descending in harmony with the process, forming a stacked block that does not collapse.The fixed number of stacked products is counted by the number of punches, and the support lifting shaft 3 is rapidly lowered to die the stacked block. 1 and discharged to the side by the busher 7, and during the discharge, the temporary support plate 10 advances to receive the punched product c in place of the support lifting shaft 3. In order to prevent an increase in the number of punched products c in the stacked blocks, a supporting lifting shaft 3 is installed in the through hole 6.
A support plate 5 through which the product is passed is installed above the descending pole of the lifting shaft 3, and the punched product is received on the support plate 5 from the support lifting shaft 3, and the busher is reciprocated on the support plate 5 to perform the punching. The punched products are pushed out to the side from the support lifting shaft, and at the same time as the busher returns to the backward position, the support lifting shaft 3 is raised at high speed and the temporary support plate 10 is retracted, so that the products are stacked on the temporary support plate 10. The device receives the punched products c on the support lifting shaft 3 and restarts stacking of a certain number of received punched products.
The related operations facilitate the stacking of a certain number of high-volume, high-efficiency processed resin sheet molded and punched products (c) into blocks, and post-processing such as packaging and sealing with resin film or loading a certain number of pieces into transport cases. , which can be easily performed without the need for counting.
