Description

[Detailed Description of the Invention] The present invention relates to a simple loading device for stacking products, which is installed before the final stage of feeding in a transfer press.

Conventionally, in a transfer press, the molded products are sent onto a delivery conveyor by a feed bar, and the products on the delivery conveyor are placed into pallets one by one by hand by a worker. By the way, if the products were placed into pallets one by one by hand, the production speed could not be increased, resulting in poor production efficiency.

Therefore, the object of the present invention is to increase the product processing speed of workers by placing a plurality of products on the carry-out conveyor at a time in the final process of transporting the products of the transfer press.

That is, the present invention provides a lifter for stacking products at a position in front of the feed bar side of the carry-out conveyor that carries out products from the feed bar of the transfer press, and the rear end of the feed bar is located between the lifter for stacking products and the carry-out conveyor. The feed bar is configured to enable a cross-feeding process, and intermittent fingers are provided opposite to the rear end of the feed bar so as to approach the feed bar intermittently to enable the feed bar to hold and convey a plurality of products on the product stacking lifter. It is characterized by:

According to the above configuration, a plurality of products sequentially sent from the transfer press by the feed bar are placed on the lifter provided in front of the carry-out conveyor, and a plurality of products are transferred one by one onto the carry-out conveyor by an intermittent finger provided at the end of the feed bar. Since it is possible to load products onto pallets, it is possible to significantly reduce the number of times an operator has to load products onto a pallet, thereby increasing production speed.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In FIGS. 1 and 2, 1 is a pair of feed bars for transporting products in a transfer press, 2 is a carry-out conveyor that carries the product C from feed bar 1 to the vicinity of pallet 3, and 4 is the feed bar 1 side of carry-out conveyor 2. A lifter for stacking products (hereinafter simply referred to as a lifter) is provided in front of the product stacker and is composed of a product receiving plate 5 and a hydraulic cylinder 6 for raising and lowering the product receiving plate 5. The feed bar 1 is provided with a predetermined number of a pair of stationary fingers 12 for holding and conveying the product C on the lower die after pressing onto the lower die or receiving plate 5 for the next press step. An intermittent type finger 7 is provided at the end to face the product C and to intermittently hold the product C and transport it from the lifter position a on the receiving plate 5 of the lifter 4 to the sending final process position b on the carry-out conveyor 2. There is. That is, each intermittent finger 7, as shown in FIGS. 3 to 5,
An air cylinder 8 is attached to the top surface of the feed bar 1 and is operated intermittently.
It is composed of a sliding body 9 that is freely movable in the direction B perpendicular to the direction B, and a pair of claws 10 for holding the product attached to the upper surface of the sliding body 9, and each sliding body 9 is made to protrude toward the product side. It is possible to clamp a plurality of products C between the claws 10, and by operating the feed bar 1 a predetermined number of times with the slider 9 in the retracted position,
A plurality of products C, which are conveyed and stacked on the receiving plate 5 by the stationary fingers 12, can be held between the claws 10 by protruding the sliding body 9, and conveyed onto the carry-out conveyor 2. . Note that reference numeral 11 indicates guide rods provided on both sides of the sliding body 9.

Next, the operation will be explained based on FIGS. 6 to 14. The pair of feed bars 1 are configured to be able to approach and separate from each other, move up and down, and reciprocate, and when the feed bars 1 approach, a stationary finger 12 and a claw 10
The product C is held by the intermittent finger 7 in the protruding state.

Claw 1 where intermittent finger 7 does not hold product C
0, in the lowered position of the feed bar 1 shown in FIG.
3, and raise the feed bar 1 as shown in FIG. Next, the feed bar 1 is moved in the conveying direction A by a predetermined stroke to feed the eighth
As shown in the figure, place the product C above the receiving plate 5 of the lifter 4, lower the feed bar 1, and place the product C
is placed on the receiving plate 5, and the product C is placed on the receiving plate 5 with the feed bar 1 separated as shown in FIG. Thereafter, the feed bar 1 is raised again in a separated state, moved back, returned to its original position, and lowered, and the operations shown in FIGS. 6 to 9 are repeated a predetermined number of times to stack the products C on the receiving plate 5. At this time, the receiving plate 5 of the lifter 4 is moved by the hydraulic cylinder 6 to the product C.
is moved downward by a predetermined amount each time it is received. Then, when a plurality of products C (for example, 3 to 4 products) are stacked, the receiving plate 5 is raised by the hydraulic cylinder 6 and the intermittent finger 7 is activated, that is, the air cylinder 8 is used to clamp the product C, as shown in FIG. 10 is made to protrude inward, and as shown in FIG. 11, the feed bar 1 is brought close to clamp the plurality of products C on the receiving plate 5 together, as shown in FIGS. 12 to 14. The feed bar 1 is raised and moved, and then lowered and separated to place a plurality of products C on the conveyor 2. Thereafter, the feed bar 1 is raised, returned, and lowered, and the pawl 10 of the intermittent finger shown in FIG. 6 is returned to the retracted state, and these operations are repeated. Further, the conveyor 2 is moved by a predetermined amount to prepare for the next delivery.

As described above, according to the present invention, a plurality of products from the transfer press are stacked on the product stacking lifter, and then the products are stacked on the feed bar by an intermittent finger disposed opposite to the rear end of the feed bar. In connection with the feeding process, multiple products can be loaded onto the unloading conveyor at once, so the number of manual transfers of products from the unloading conveyor to pallets can be significantly reduced (1/3 to 1/5) with an extremely simple configuration. can be reduced and thus production speed can be increased.
