The container is placed on a pair of half shelves 16, 16 facing each other between a pair of supports 13, 13.

Reference numeral 17 denotes an extrusion device disposed on the opposite side of the transfer device 12 from the frame 1, on the front side between the supports 13, 13. This extrusion device includes a support rail 18 and a support rail provided horizontally from its upper end to the transfer device 12 side. 19 and a pair of X-shaped link bars 20
It is made up of. A plate-shaped movable body 21 having approximately the same length as the support column 18 is attached to the support rail 19 so as to be suspended from the support rail 19 and forcibly moved along the support rail 19. 21
A is a roller attached to the upper end of the movable body 21 and fitted into the support rail 19; 22 is the movable body 21;
An air cylinder is attached to the upper end of the support rail 19 to move it, and its rod is attached to the end of the support rail 19.

A pair of X-shaped link bars 20 are pivoted to each other at approximately their longitudinal centers, and the upper ends of the link bars 20A and 20B are pivoted to the support 18 and the movable body 21, respectively. It is worn. 23 is the lower part of the column 18, 24 is the movable body 2
Sections C each installed longitudinally at the bottom of 1.
It is a letter-shaped roller guide, and the support roller 25 attached to the lower end of the link bar 20A is the roller guide 2.
4, the support rollers 26 attached to the lower end of the link bar 20B are movably fitted into the roller guides 23, and the movable body 21 is moved to the transfer device 12.
When the link bars 20A and 20B are moved to the side, the top and bottom of the link bars 20A and 20B are separated from each other, and the entire hanging movable body 21 is pushed toward the frame 1 side, and the movable body 21 is moved in the opposite direction to the transfer device 12. When moved, the upper and lower portions of the link bars 20A and 20B come close to each other, and the entire movable body 21 is separated from the frame 1.

Reference numeral 27 denotes an extrusion air cylinder mounted on the side opposite to the link bar 20 of the movable body 21 with its axis in the horizontal direction, and corresponds to the tray 6 of each stage.
It is placed at a height that allows it to be joined to the side of the container placed above it. Reference numeral 28 denotes a mounting base for the air cylinder 27 fixed to the movable body 21, and the air cylinder 27 is mounted to the mounting base through a long hole 29 extending in the axial direction of the air cylinder 27. It is now possible to adjust the position. 30 is the air cylinder 27
This is a hole provided in the movable body for retracting the movable body.

Reference numeral 31 denotes a carry-in conveyor which is stacked under the extrusion device 17 and inserted between the supports 13 and 13 of the storage device 12 from below, and the containers carried in by this conveyor are placed in half-shelves 16 and 16. It is configured to be supported between the two and raised to the required height. 32 is a container.

The air cylinder 22 can be replaced with an endless chain, and in this case, the movable body 21 is reciprocated by reversing the chain. As the transfer station 12, for example,
It is also possible to use a device disclosed in Japanese Patent No. 41898 in which a vertical support is provided with a station on which a container is placed so as to be movable up and down.

This device drives each chain 4 to
The container is removed or stored by moving the container to the removal port or storage port. Normally, the link bars 20 are located close to each other and in front of the transfer device 12, and the air cylinder 2 of the movable body 21
The rod number 7 is in the "on" state. When returning the container to the storage device, the container is carried between the supports 13, 13 of the transfer device 12 by the carry-in conveyor 31 and stopped at that position. Then, the transfer device 1
Each of the two transfer chains 15 is driven, and the half shelves 16 lower than the container are engaged with both sides of the container and lifted up, and the container is stopped in front of the tray 6 of the desired stage. A tray 6 for storing containers is driven by a chain 4 and stopped in front of a transfer device 12.

On the other hand, the air cylinder 22 attached to the upper end of the movable body 21 is driven to move the movable body 21 to the transfer device 1.
Move it to 2. The movable body 21 is in a hanging shape, and a link bar 20 whose upper end is pivoted is arranged between the movable body 21 and the support column 18.
In addition, since each lower end of the link bar 20 is movably attached to roller guides 23 and 24 fixed to the column 18 and the movable body 21, as the movable body 21 moves, the upper and lower ends of the link bar 20 are separated from each other. As the movable body 21 is pushed, the movable body 2
1 moves toward the transfer device 12 while maintaining a vertical state. Also, since the air cylinder 27 at a height corresponding to the container lifted by the transfer device 12 is activated and the rod is brought out, the container on the lifted half-shelf 16 is transferred via the air cylinder 27. The movable body 21 pushes it and transfers it to the tray 6 in front of it. At this time, since the air cylinder 27 that pushes the container is in the "out" position, it is possible to completely transfer the container onto the tray 6 located inside the outer surface of the frame 1, and also to Since the air cylinder 27 is turned on and its tip only advances to the vicinity of the frame 1, even if the chains 3 of stages other than the stage for returning the container are driven, the air cylinder 27 is not connected to the container. There is no risk of being hit. Therefore, the container is placed in the tray 6 of the predetermined level.
The top can be completely returned to the top, and the chains 3 of other stages can be driven to prepare for loading and unloading of containers, allowing for efficient loading and unloading of containers. When the container is returned to the tray 6, the air cylinder 22 of the movable body 21 is turned on and the movable body 21 is returned to the support column 18, so that the link bars 20 come close to each other and the air cylinder 27
will also be restored. This operation is repeated to sequentially return the containers onto the tray 6.

As described above, this device uses endless transfer chains 15, 15 to sequentially lift containers to a predetermined height via half shelves 16, 16, and the half shelves are provided at approximately equal intervals along the entire length of chain 15. Since the container is in its original position, no time is required to return it to its original position, reducing the time required to lift the container. Extrusion device 1
Since the movable body 21 of No. 7 is moved by a pair of cross bars 20, when the link bar 20 is stored,
They overlap each other in the vertical direction, making it possible to extremely reduce the bulk of the movement of the container, and reducing the installation space of the extrusion device 17.
The inside of a warehouse etc. can be used effectively. Movable body 21
is in a hanging shape, but since it is pushed by the link bar 20, it is possible to move the movable body 21 while maintaining a vertical state, and the container on the half shelf 16 can be reliably moved onto the tray 6. .

In this embodiment, the transfer device 12 and the extrusion device 17
is disposed at the end of the chain 3 in the long diameter direction, so if the chain 3 stretches due to use and the stretch is absorbed by moving the support shaft 3, the tray 6
The distance between the upper container and the air cylinder 27 becomes smaller. In this case, by retracting the mounting position of the air cylinder 27 with respect to the mounting base 28 using the elongated hole 29, when the movable body 21 is moved toward the frame 1 side, the air cylinder can be attached to the container of the chain 3 being driven. 27 can be prevented from hitting. When the transfer device 12 and the extrusion device 17 are arranged on the short diameter side of the chain 3, the elongated hole 29 of the mounting base 28 is unnecessary.

In this invention, a pair of link bars configured in a pantograph shape are attached between the movable body which is attached to the support rail in a hanging manner and the column, so that when the movable body is moved, the link bars move upward and downward. Since the two move away from each other and push the movable body, the movable body can be moved while maintaining a vertical state, and the container can be reliably pushed. In addition, since the pair of link bars overlap each other, it is possible to extremely reduce the bulk of the extrusion device in the direction in which the container is moved.
Installation space can be used effectively. Since the movable body has an extrusion means such as an air cylinder on the opposite side of the link bar, it is possible to reliably store containers in the required tiers in the storage device, and to prevent unused extrusion means from interfering with the storage device. It can be prevented.
