The guide device 8 includes an elevating body 10 connected to the piston rod of the cylinder device 9, a flat guide material 11 and an L-shaped guide material 1 erected from the elevating body 1o.
It consists of 2A and 12B.

The elevating body 10 is guided by a pair of left and right guide grooves 13A and 13B attached to the fixed frame 6, and is configured to move up and down on a fixed path.

Further, the flat guide material 11 is located on the transfer press side and in the middle in the left-right direction, and further includes an L-shaped guide material 12A,
12B is located on the side away from the transfer press and at both left and right ends.

Reference numeral 14 denotes a stacking device disposed above the guide device 8, in which the products 1 are intermittently dropped and fed by the feed bar 1.
Accept and stack 5.

That is, 16 is a support attached to the fixed frame 6, and 17 is a product guide disposed within this support 16, which is attached to this support 16 so as to be replaceable.

Shutter plates 18A and 18B are located below the support 16, and are configured to be retractable laterally outward from below the support.

That is, a pair of left and right boards 19A, 1 are integrated with the fixed frame 6.
Horizontal cylinder devices 20A, 20B are mounted on 9B, respectively, and the shutter plates 18A, 18B are mounted on the piston ronds of these cylinder devices 20A, 20B.

And shutter plate 18A. The guide bodies 22A and 22B of the guide rods 21A and 21B connected from the substrate 18B are connected to the substrate 1.
It is provided on 9A and 19B.

23A and 23B are backward limit detection devices (limit switches) for the shutter plates 18A and 18B, and 24A and 24B are forward limit detection devices (limit switches).

Reference numeral 25 denotes a lifting platform located below the shutter plates 18A, 18B and within the guide device 8, and its entry into the guide device 8 is performed on both sides thereof, avoiding the flat guide material 11.

The lifting platform 25 is raised and lowered by guide rods 27A and 27B using a cylinder device 26 (lifting drive device) attached to the fixed frame 6.
This will be carried out under the guidance of

28 is a phototube switch that detects that a certain amount (a certain number or a certain height) of products 15 has been received by the shutter plates 18A, 18B, and the cylinder devices 20A, 20B are contracted in response to the detection signal.

29 is an upward limit detection device (limit switch) of the guide device 8, 30 is a downward limit detection device (limit switch),
The detection signals from these stop the expansion and contraction movement of the cylinder device 9.

Reference numerals 81A, 81B, and 81C are lowering position detecting devices (limits, switches) for the lifting platform 25, and the contraction movement of the cylinder device 26 is stopped in response to detection signals thereof.

32 is a phototube switch that detects that a certain amount of products 15 have been received by the lifting table 25.

The drawing shows the product 15 before it is received, ie in an empty state.

At this time, the shutter plate 18A. 18B is in the plunge position, and the guide device 8 and the lifting platform 25 are in the upper limit position.

In this state, the products 15 are sequentially and intermittently carried out from the transfer press by the feed bar 1, and are then dropped and fed into the stacking device 14.

Supplied product 15 is Sha/Yu! Plate 18A, 1.8B
It is accepted and piled up.

When a certain amount of products 15- are stacked, the phototube switch 28 detects this, and the detection signal causes the cylinder devices 20A, 20B to contract.

As a result, the shutter plates 18A and 18B move back and forth, so that the 15 stacked products fall into the guide device 8 and are received by the lifting table 26.

The lifting table 25 that has received the 15 groups of products is lowered by the contraction of the cylinder device 26, and its lowering is stopped by detection by the upper lowering position detection device 31A.

The cylinder devices 20A and 20B are the backward limit detection device 23.
At the same time as detection is made by A and 23B, the movement moves to extension, and is stopped by detection by advancement limit detection devices 24A and 24B.

As a result, during the intermittent time of the products 15 being carried out intermittently, the group of stacked products 15 falls due to the withdrawal of the shutter plates 18A, 18, and returns to the product 15 receiving position by entering.

In addition, the fallen product 15 is the guide material 11, 12A, 12B.
The robot is received on the elevator platform 25 while being guided by the robot.

By repeating the above-described operations, the lifting table 25 is lowered in stages, and the amount of products 15 received by the lifting table 25, that is, in the guide device 8, gradually increases.

The elevator platform 25 is detected by the lowest descending position detection device 31C, and when the product 15 to be dropped reaches a certain amount, the phototube switch 32 detects this.

This detection signal causes the clamping claws of the stack conversion device 3 to
It avoids the shape guide members 12A and 12B and enters the upper, lower, and both sides of the stacked products 15 group.

After the 15 groups of products are placed on the stack converting device 3 by lowering the lifting platform 25, the 15 groups of stacked products are held by these clamping claws.

The cylinder device 9 then contracts, lowering the guide device 8.

The lowering limit of the guide device 8 is detected by the detection device 30,
The cylinder device 9 is stopped by the detection signal, and at the same time, the stacked products 15 are taken out from the stack receiving device 2 by the stack changing device 3.

At the same time as this removal 1. The guide device 8 is raised by the extension of the cylinder device 9, and the elevating table 25 is raised by the extension of the cylinder device 26, and the raising of the guide device 8 is stopped by the detection by the detection device 29.

From the entry of the clamping claws to the lifting platform 25 and the guide device 85.
The work until ρ rises again is to remove shutter plates 18A and 18B.
This is done within the time that the products 15 are stacked.

In the above embodiment, the feed bar 1 of the transfer press shows a state in which the product 15 is intermittently dropped and fed, but this may be of a type in which the product 15 is received by a conveyor device, for example.

Further, the stacked products 15 may be taken out using a fork device (such as a forklift truck).

According to the present invention described above, the stacking device includes a stacking device, a guide device, and a lifting platform, and in particular, the stacking device includes:
a support, a product guide disposed within the support; and a product guide located near the bottom of the support that can move in and out in the lateral direction, and when a certain amount of products are stacked within the product guide, the product is moved back and forth. Since the product is configured to include a shutter that supplies the group into the guide device, products that are intermittently supplied falling can be stacked in an orderly manner by the product guide of the stacking device, and when a certain amount of products have been stacked, the shutter is retracted. This makes it possible to feed the product group to a lifting platform within the guide device.

Therefore, products can be stacked in an orderly manner with less impact and without shifting.

Moreover, the removal of a certain amount of products stacked in the guide device can be carried out while the products are being stacked in the stacking device, and this can be done without stopping the intermittent dropping supply, increasing the operating efficiency. can be improved.

In addition, since the configuration incorporates a guide device that is held movably up and down by the first lifting drive device, a stack conversion device or fork device that changes the direction of the product can be used to carry out the product. This makes it easier to handle the product later.
