Description

[Detailed Description of the Invention] The present invention relates to a device for moving a container stored in a shelving device when the container is taken out from the shelf or returned to the shelf.

Rotatable shelving devices used in various product assembly factories to store many parts of the products are already known;
As disclosed in the above publication, there is a system in which endless chains are arranged horizontally in multiple stages in the vertical direction, and containers are placed on mounting plates attached to each chain. A transfer device for moving containers taken out from or stored in this rotary shelving device is, for example,
It is disclosed in Publication No. 30605. The device disclosed in this publication has an extrusion arm whose longitudinal middle portion is pivoted to an endless chain horizontally attached to a shaft, and the lower end of this arm is connected to a horizontal guide. By guiding the arm with a rail, when the shaft attachment part of the arm to the chain is located on the outbound side of the chain, the arm can be raised upright and push the container placed on top of it, and the shaft of the arm can be When the attachment part is located on the return side of the chain, the arm should be in a nearly horizontal position,
It is configured such that a container can be placed on top of it. However, in this device, when the arm is advanced to a predetermined position, the chain is stopped, and then the chain is reversed to return the arm to its original position. Therefore, when the arm reciprocates, it takes time to stop the chain, and the drive motor must be reversible, making the structure complicated. . In addition, if the rotation speed of the motor that drives the chain is constant, the speed of the arm movement will always be approximately constant, so if you increase the movement speed of the arm, when the pushed container stops,
It is difficult to move and stop the container in a fixed position due to its inertia, and if there is a container stopper, problems such as the container colliding with it occur.

The present invention eliminates the stoppage of the chain during the reciprocating movement of the extrusion means, shortens the time required for the reciprocating movement of the extrusion means, simplifies the structure of the chain drive part, and allows containers, etc. pushed by the extrusion means When stopping an article, the object is to make it possible to quietly stop a container or the like almost in a fixed position by lowering its moving speed.

A support is slidably attached to a guide rod provided horizontally in a housing constituting a table on which an article such as a container is placed, and endless chains are spaced apart so as to rotate in the same direction as the axis of the guide rod. A sprocket wheel is attached to a sprocket wheel that is vertically rotatably supported by a horizontal shaft provided, and a connecting body is attached to a support rod that is vertically fixed to the support body so as to be vertically slidable, and is pivoted to the side surface of the chain. , and the proximal end of the extrusion arm, which is oriented in the axial direction of the guide rod, is attached to the upper part of the support so that it can swing vertically with a horizontal support shaft, leaving the receiving part, and is always moved upward by a spring. A support body having a sloped upper surface is fixed to the housing so that when the support body retreats, a support pin protruding from the receiving portion will ride up and push down the push-out arm almost horizontally. The gist is that.

To explain the device of the present invention with reference to the embodiment shown in the drawings, reference numeral 1 denotes a box-shaped housing constituting a table, and a pair of guide rods 2, 2 are installed horizontally and parallel to each other between the opposing vertical walls. is fixed to. Reference numeral 3 denotes a support member having an inverted concave shape that is installed between the guide rods 2 and 2 in a slidable manner, and 4 is a support member that is partially placed on the support member 3 and extends in the axial direction of the guide rod 2. The oriented proximal end is supported by a support shaft 5 in a horizontal direction.
The push-out arm is attached to the push-out arm so as to be swingable in the vertical direction, and its end far from the support shaft 5 serves as a push-out portion 6 for pushing the container. 7 is extrusion arm 4
The receiving part is provided so as to protrude from the supporting shaft 5 on the side opposite to the extruding part 6, and the lower surface of the receiving part is sloped, allowing the extruding arm 4 to swing upward. However, if a distance is provided between the lower surface of the push-out arm 4 and the upper surface of the support body 3, the slope of the receiving portion 7 is not required. Reference numeral 8 denotes a support pin protruding from the side surface of the receiving portion 7 in the axial direction of the support shaft 5. A roller is attached to this support pin, but this roller may be omitted.

Reference numeral 9 denotes an endless chain that rotates in the same direction as the axis of the guide rod 2, which is connected to a horizontal shaft 11 that is cantilevered at a distance from a pair of bearings 10 fixed to the bottom wall of the housing 1. , 11 via sprocket wheels 12, 12 which are vertically rotatably supported. Reference numeral 13 denotes a connecting body that is pivotally attached to the side surface of the chain 9 on the side opposite to the bearing 10, and this connects the support rod 1 that is fixed to the support body 3 with its axis in the vertical direction.
4, and the support rod 14 is longer than the vertical distance between the forward and backward paths of the chain 9. Therefore, as the chain 9 rotates, the push-out arm 4 moves via the support rod 14 and the support body 3. Since the connecting body 13 slides with respect to the support rod 14, the supporting body 3 and the push-out arm 4 can be reciprocated by simply moving the connecting body 13 from its outward path to its return path without stopping the chain 9. Is possible.

Reference numeral 15 denotes a support disposed at a position facing the support pin 8 of the push-out arm 4 in the axial direction of the guide rod 2, and this is fixed to the housing 1.
The upper surface is sloped so that the end side facing the extrusion arm 4 is lowered, and when the support pin 8 of the extrusion arm 4 that has retreated is placed on the slope, the extrusion arm 4 is placed on the slope. It is set at a height that allows it to be pushed down and become almost horizontal. Reference numeral 16 denotes a spring interposed between the push-out arm 4 and the support body 3 on the side closer to the push-out portion 6 than the support shaft 5, and the push-out arm 4 is biased upward. The spring 16 can be provided at any position, and can be applied by urging the push-out arm 4 upward. 17 is a transfer device attached to the housing 1 on both sides of the push-out arm 4 in the radial direction of the guide rod 2, and is provided so as to protrude above the push-out arm 4 when it is approximately horizontal;
It consists of a conveyor of belts and rollers that are forcibly driven. Reference numeral 18 denotes a container, and reference numeral 19 denotes a column on which a table constituted by the housing 1 is mounted so that it can move up and down and be stopped at a fixed position.

The container is moved by this device, as illustrated in FIG. The container is placed on the transfer device 17 by sliding it horizontally or by lowering it from above and below. Then, the transfer device 17
is driven in the direction of the arrow in FIG. 1, and the container is placed on a container placement portion (not shown) such as a tray of a shelving device or a conveyor for transportation located in front of the container. When the entire container passes over the push-out arm 4, the chain 9 is driven in the same direction as the moving direction of the transfer device 17, and the connecting body 13
Since the push-out arm 4 is moved together with the support body 3 via the support rod 14, the support pin 8 is attached to the support body 1.
Stay away from 5. As the support pin 8 moves on the support body 15, the push-out arm 4 is pushed upward by the force of the spring 16, and its push-out portion 6 projects above the transfer device 17 as shown in FIG. , it becomes possible to push the side walls of the container. In this state, the chain 8 further rotates, so the push-out arm 4 moves the container that is still partially on the housing 1 side.
The container is pushed to displace the entire container onto the receiver.

When the pusher arm 4 pushes and moves the container to a predetermined position on the loading section, the connecting body 13 slides against the support rod 14 and descends along the sprocket wheel 12, and now the return path of the chain 8 is moved. As the connecting body 13 moves, the push-out arm 4 retreats together with the support 3, and when the support pin 8 fully rests on the support 15 and the push-out arm 4 returns to the horizontal state as shown in FIG. 8 stopped,
The next container is placed on the transfer device 17 and the process is repeated. The transfer device 17 may be stopped after the entire container has passed over the extrusion arm 4, or may be operated continuously. And the transfer device 1
7 and chain 8 may be driven by a signal from a limit switch or the like placed at an appropriate location, or may be driven manually.

As described above, this device connects the connecting body 13 which is pivoted to the chain 8 to the support rod 1 which is fixed to the support body 3.
4, it is possible to reciprocate the extrusion arm 4 by simply rotating the chain 8 in one direction. That is, since the extrusion arm 4 can reciprocate without stopping the chain 8 in the middle, there is no need to stop the chain 8, the time required for the reciprocation of the extrusion arm 4 can be shortened, and the container can be moved easily. can be carried out efficiently, and since the motor for driving the chain 8 only rotates in one direction, the structure of the drive section of the chain 8 can be simplified.

The pushing arm 4 can be moved forward or backward by moving the connecting body 13 along the support rod 14.
This is done by moving only the connecting body 14 from the outbound path of the chain 8 to the return path. Therefore, since the coupling body 13 moves from a linear motion to a circular motion along the sprocket wheel 12 and moves the push-out arm 4 together with the support 3, when the coupling body 13 starts circular motion, the moving speed of the push-out arm 4 changes. Since the push-out arm 4 is then moved backward, the container can be stopped quietly at the fixed position on the loading section, and the container can be stopped at the fixed position on the loading section regardless of its weight. It is possible to do so. In addition, even if there is a stopper for the container on the platform, the container can be stopped without colliding with the stopper, and even if the contents of the container are easily deformed or damaged, the container can be stopped without being damaged or damaged. Containers can be moved without deforming them. Therefore, as shown in the embodiment, the support 19 is configured so that this device can be moved up and down while maintaining a horizontal state, and can be stopped at a predetermined position.
By attaching the container to the shelf, it is possible to efficiently receive a container from each shelf of a multi-tiered shelving system, move it to the next location, or return a removed container to its original position on the shelving system. And it can be done quietly.

The push-out arm 4, which is attached to the upper part of the support body 3 that reciprocates as the chain 9 turns so as to be able to swing up and down with a support shaft 5, is normally biased upwardly by a spring 16 so as to be tilted upright. As the support body 3 moves forward, the tip of the push-out arm 4 can push out and transfer the container, and when the support body 3 is retreated, the container protrudes into the receiving part 7 at the base end. The support 1 with the provided support pin 8 fixed to the housing 1
5, the push-out arm 4 can be pushed down against the elastic force of the spring 16 and made almost horizontal, thereby allowing the container to be pushed out without touching the push-out arm 4. When the chain 9 turns with the container in the predetermined position, the support 3 moves forward and the support pin 8 moves away from the slope of the support 15. The push-out arm 4 can be tilted upward by the elastic force of the spring 16, and the container can be pushed out and transferred as described above.

In this embodiment, the container placed on the transfer device 17 is sent out.
Since the container placed on the table can be pushed and moved, the transfer device 17 can also be a fixed stand, and the container can be placed thereon. The extrusion means is configured by pivoting an extrusion arm 4 to a support 3 so as to be movable up and down, but this can be done by making it possible to extrude a container placed on a table or by using an arbitrary configuration. Extrusion means can be used.
