The conveyed material ascending path and the conveyed material descending path are constructed as follows. In other words, two chain elevators, each consisting of an endless chain having a plurality of receiving pieces hung on sprockets that are vertically separated, are installed separated from each other in the direction of the sprocket rotation axis to form a pair of elevators, and this pair of elevators is called a chain elevator. They are arranged in parallel at three equal intervals in the direction perpendicular to the separation direction. The front pair of elevators and the intermediate pair of elevators form a conveyed material ascending path in which the chain paths inside each other are in the upward direction, and the intermediate pair of elevators and the rear pair of elevators The inner chain path constitutes a conveyed material descending path in the downward direction. Further, a carrying device is provided for carrying the material to be transported from the front of the lower end of the front elevator pair onto the platform of the material ascending path,
A forward and backward feeding device is provided for transferring the conveyed material along with the platform from the upper end of the conveyed material ascending path to the upper end of the conveyed material descending path, and a carry-out device carries out the conveyed material rearward from the lower end of the conveyed material descending path. and a table return device for returning an empty platform from the lower end of the conveyed material descending path to the lower end of the conveyed material ascending path.

According to this configuration, a plurality of conveyed materials are placed on a pair of rod-shaped platforms, and a conveyed material ascending path and a conveyed material descending path for stocking the conveyed materials are provided side by side, and a conveyed material ascending path and a conveyed material descending path are provided side by side. The chain elevator that constitutes the conveyance material descending path has a plurality of receiving pieces on the chain, so that platforms can be placed in a plurality of upper and lower stages. Therefore, a large amount of conveyed materials can be stocked in a small space.

In addition, the platform on which the material to be transported is placed is moved from the carrying-in device to the unloading device by means of the material ascending path, the forward/backward feeding device, and the material descending path, so that the material carried in first can be carried out sequentially. I can do it. In this case, since a plurality of materials to be transported can be sequentially placed on the platform from the front, loading and unloading can be carried out independently, and therefore loading and unloading can be carried out simultaneously in accordance with the previous and subsequent processes.

Embodiment An embodiment of the present invention is shown in FIGS. 1 to 3. This stocking device has a plurality of conveyed materials 2 placed on a bar-shaped platform 1, and a conveyed material ascending path A and a conveyed material descending path B for stocking these conveyed materials 2 are arranged side by side, and a carry-in device 3 and , a carry-out device 4, a back-and-forth feed device 5, and a platform return device 6 are provided.

The conveyed material ascending path A and the conveyed material descending path B are constructed as follows. In other words, three pairs of elevators 7.8°9 are provided at equal intervals, and the front and middle pairs of elevators 7 and 8 form the transport material ascending path A, and the intermediate and rear elevator pairs 8°9 form the transport material descending path. B is configured respectively.

Each pair of elevators 7 to 9 includes two chain elevators 14, each of which is formed by hanging an endless chain 11 having a plurality of receiving pieces 10 on sprockets 12 and 13 spaced apart vertically, and spaced apart from each other in the direction of the sprocket rotation axis. It was established. Each receiving piece 1
0 is a side-shaped one, 90mm from pin 10ae
It can be rotated up and down within a degree angle. Although not shown, each chain elevator 14 includes a frame, a drive device for the sprockets 12 and 13, and guide means for preventing slack in the chain 11 and inclination of the receiving piece 10.

The carry-in bag W3 and the carry-out device 4 each include a belt conveyor or the like having a feeding claw.

The feeding device 5 has a push piece 19 attached to a chain 18 which is hung around a pair of sprockets 1-16°17, and is provided with a slide base 20 as shown in FIG. The slide table 20 can be moved inward from the chain elevator 14 from the position shown in FIG. 2 by driving a cylinder device or the like (arrow Q).
direction).

The platform return device 6 includes an endless rotating belt 2 on which the platform 1 is placed.
1. As shown in FIG. 3, the rotating belt 21 is made up of two ropes 21a arranged in a ladder shape with connecting members 21b, into which the receiving piece 10 of the chain elevator 14 can enter.

Operation As shown in FIG. 1, the lowermost stage 1 of the conveyance material ascending path A is located at approximately the same height as the carry-in device 3, and the conveyance materials 2 are sequentially fed in the direction of arrow R from the carry-in device 3. When the platform 1 is fully loaded, each chain elevator 14 is raised by one pitch of the receiving piece 10.

Repeat this operation.

When the conveyed material rises to the upper end of the conveyed material ascending path A, the forward and backward feeding device 5
pushes the platform 1 with the pushing piece 19, and sends the material 2 placed on the platform 1 to the material descending path B.

At this time, in synchronization with the movement of the push piece 19, the slide base 20
(Fig. 2) moves forward. Therefore, the mounting table 1 is placed on the slide table 20. When the feeding by the push piece 19 is finished, the slide base 20 retreats.

In this way, the platform 1 that has been transferred to the upper end of the conveyed material descending path B moves down this descending path B.

When the material 2 on the platform 1 reaches the lowest stage, the material 2 on the platform 1 is transferred to the unloading device 4.
It is carried out backwards (in the direction of arrow S).

The empty platform 1 on which the conveyed material 2 has been lowered is moved to a chain elevator 14.
When the receiving piece 10 rotates around the lower sprocket 13, it falls from the receiving piece 10 onto the rotating band 21 of the return device 6. The platform return device 6 is driven in synchronization with the chain elevator 14, sends the platform 1 to the lower part of the conveyed material ascending path A, and then stops. In this position, the front and middle elevator pairs 7.8 are
When the receiving piece 10 rotates around the lower sprocket 13, the receiving piece 10 picks up the platform 1 on the return device 6. Note that when the receiving piece 10 moves around the lower sprocket 13, its attitude changes by 90° around the pin 10a due to its own weight.

In this way, stocking and loading/unloading is carried out,
This configuration provides the following advantages.

That is, a plurality of conveyed materials 2 are placed on a pair of rod-shaped platforms 1, and a material ascending path A and a conveying material descending path B are provided side by side to stock the conveyed materials 2. The chain elevator 14 that constitutes the path A and the conveyed material descending path B has a chain 11 provided with a plurality of receiving pieces 10, so that the platform 1 can be placed in a plurality of upper and lower stages. Therefore,
A large amount of conveyed materials 2 can be stocked in a small space.

Further, the platform 1 on which the conveyed material 2 is placed is connected to the conveyed material top-ascending path A.
Since the conveyance materials 2 are moved from the carry-in device 3 to the carry-out device 4 by the back-and-forth feeding device 5 and the conveyed material descending path B, the conveyed materials 2 carried in first can be sequentially carried out. In this case, since a plurality of conveyed materials 2 can be sequentially sent and placed on the platform 1 from the front side, loading and unloading can be performed independently, and therefore loading and unloading can be performed in accordance with the previous and subsequent processes.
