It is a shelving device.

[0006] In the second invention, the transmitting device includes:
A peripheral chain, and a plurality of locking members that are provided at a position that equally divides the peripheral length of the peripheral chain, and that are locked with the transported object and that deliver the transported object. By the circumferential movement of the circumferential chain, the locking body on the sending drive side of the circumferential chain is locked to a conveyed object and sent out at a predetermined feed length, and after the feeding is completed, the next locked body rotates. A shelf device according to a first aspect of the present invention, characterized in that the chain is driven on a delivery drive side.

According to a third aspect of the present invention, a delivery member for receiving a conveyed article is provided at a front portion of the receiving conveyer, and the delivery member advances and retreats in a front-rear direction with a predetermined reciprocation length and sends out the conveyed article. Sometimes a forward / backward transfer device that receives the conveyed material at a position moved to the shelf cart side.
Alternatively, it is a shelf device according to the second invention.

According to a fourth aspect of the present invention, the stop height control means sets the receiving conveyor to a receiving height, and sets the receiving conveyor to a receiving height if the previous stopping height was higher than the receiving height. The shelving device according to the first or second invention, characterized in that it is lowered to temporarily stop at a position lower than the receiving height, and then is raised to the receiving height and stopped.

According to a fifth aspect of the present invention, there is provided a shelving method for accommodating a conveyed product on a shelf, the step of receiving the conveyed product by a receiving conveyer, raising or lowering the receiving conveyer on which the conveyed product is placed, and Transporting the receiving conveyor to the shelving vehicle side to make it closer to the shelves, and transferring the conveyed material to the empty shelves of the shelving vehicle. Is stored on a shelf.

According to a sixth aspect of the present invention, there is provided a method for setting a receiving conveyor at a receiving height in a shelving device for storing a conveyed product on a shelf, wherein the previous stopping height of the receiving conveyor is higher than the receiving height. In the case where the receiving conveyor is lowered and temporarily stopped at a position lower than the receiving height, then raised to the receiving height and stopped, the receiving conveyor is received at the receiving height in the shelving device. It is a method to set to.

(Operation) In the shelving apparatus according to the first aspect of the present invention, the goods conveyed by the conveyor are received by the receiving conveyer, the receiving conveyer is raised and lowered by the elevating device, and the stop height control means is used. The stop height of the receiving conveyor is controlled, and the conveyed article can be sent out from the receiving conveyor to the shelf and stored by the sending device. Thus, for example, in furniture manufacturing, the operation of transferring a transport base plate on which furniture parts are arranged at the top from a conveyor to a shelf can be mechanized. Therefore, the work efficiency is improved, and the cost balance between profit and maintenance cost in the long term can be improved.

When the feed length is set to a long length, the next lock is set to wait on the feed drive side of the peripheral chain after the feed is completed. In this case, it is only necessary to extend the chain and extend the space between the sprockets. it can. In addition, if the peripheral chain is used, the speed of the delivery can be easily adjusted by controlling the number of rotations of the sprocket. Therefore, when a non-fixed object is included in the conveyed object, the speed can be adjusted so that the non-fixed object does not drop due to sudden movement.

[0013] In the shelf device according to the third invention,
A delivery member for receiving the conveyed article is provided at the front of the receiving conveyor, and the delivery member moves back and forth with a predetermined length in the front-rear direction,
When sending out the conveyed goods, it has an advance / retreat delivery device that receives the conveyed goods at the position moved to the shelf cart side, so compared with the structure that sends out the conveyed goods only with the sending device,
The shelf can be reliably received at the intermediate portion, and the shelf cart can be arranged at a position farther from the shelf storage device. This allows more space around the shelving device,
Various accompanying operations become easier.

In the shelf device according to the fourth invention,
Stop height control means, when setting the receiving conveyor to the receiving height, if the previous stop height was higher than the receiving height, after lowering the receiving conveyor and temporarily stopping at a position lower than the receiving height Since the height is raised to the receiving height and stopped, it can be stopped at an almost accurate height with little error. That is, the lifting device is generally stopped by a brake in order to reduce the impact at the time of stopping. But,
In this structure, when the elevating unit is lowered and stopped,
There is a great difference in the load on the brake when it is raised and stopped. That is, in the case of stopping by lowering, the inertia force is increased because the moving direction overlaps with the direction of attraction, so that the braking distance is long and the distance is hard to be uniform. On the other hand, in the case of raising and stopping, the moving direction is the direction of the repulsive force, so that the weight of the elevating portion is offset and the inertia force is reduced, so that the braking distance is short and uniform. As described above, if the receiving conveyor is lowered and temporarily stopped at a position lower than the receiving height, and then raised to the receiving height and stopped, it can be stopped almost exactly at a preset height.

[0015] In the method for storing shelves according to the fifth invention,
The conveyed goods are received by the receiving conveyer, the conveyer on which the conveyed goods are loaded is raised or lowered, stopped according to the height of the empty shelf of the shelf, and the receiving conveyer is pushed out toward the shelf by a predetermined length to approach the shelf. Since the transported goods are sent out and transferred to empty shelves of the shelf cart, the receiving conveyor can be moved to the shelf cart side by a predetermined length before being sent out by the sending device, so that the sending device alone can send out the goods. Can be arranged at a position more distant from the shelving device as compared with the structure in which the shelves are constructed. As a result, a space around the shelving device can be provided and various accompanying operations can be easily performed.

In the method for setting the receiving conveyor to the receiving height in the shelf device according to the sixth invention, when the receiving conveyor is set to the receiving height, the last stop height of the receiving conveyor is set to the receiving height. If the height is higher than the height, the receiving conveyor is lowered, temporarily stopped at a position lower than the receiving height, and then raised to the receiving height and stopped. It can be stopped at almost the exact height with less.

(Operation) FIG. 4 is a schematic plan view showing an example of a process using a shelving device, and FIG. 5 is a schematic side view of a shelf cart. The operation of the shelf device according to the present invention will be described with reference to FIGS. Furniture components (not shown) are loaded from the shelf truck 6 on a transfer board (not shown) placed on the transfer conveyor 71. The transport base plate is sent to the painting work table 73 through the transport conveyor 72, and the furniture parts are painted. The transport base plate is sent to the shelving device A through the transport conveyors 74 and 75.

The receiving conveyor 3 of the shelving apparatus A stands by at the same height as each transport conveyor. When the transport base plate moves to the receiving conveyor 3 and the leading end thereof comes into contact with the contact sensor 306, the drive motor 25 operates and the lifting chain 2
2 is driven to raise or lower the elevating platform 28, and the receiving conveyor 3 is stopped at the same height as the empty rack 60 of the rack 6a. The detection of the empty shelf 60 is performed by known detection means including the counting of the height detection fitting 16 by the sensor 34.

When the receiving conveyor 3 stops at the same height as the vacant shelf 60, the air cylinder 43 operates to move the reciprocating table 40 forward. Thereby, the delivery rollers 44, 4
5 moves forward, so that the transport base plate can be delivered to the receiving conveyor 3 at a position slightly away from the receiving conveyor 3 (illustrated by imaginary lines in FIG. 3).

Next, the geared motor 56 operates,
The peripheral movement chain 54 rotates and the upper locking member 57 on the sending drive side locks the transport base plate and sends it forward, that is, toward the shelf truck 6a. At this time, the locking member 57 moves to above the front sprocket 53, and the other locking member 57 moves to below the rear sprocket 52 and stops. When the transport base plate passes over the transfer rollers 44 and 45 and moves on the shelf 60, the air cylinder 43 is operated, and the advance / retreat table 40 moves backward and returns to the original position. Then, the geared motor 56 is operated to cause the peripheral chain 54 to rotate, so that the rear locking member 57 stands by on the rear sprocket 52.

The drive motor 25 is operated, and the elevating chain 22 is driven in the direction opposite to the above, the elevating table 28 is raised or lowered, and the receiving conveyor 3 is set at the original receiving height. If the last stop height of the elevator 28 was lower than the receiving height (the last time it was lowered), it is raised as it is and the tap member 28 of the elevator 28 is moved.
5 stops almost at the position where the switch of the origin limit switch 17 is hit. If the last stop height was higher than the receiving height (the last time it was raised), the elevator 28, that is, the receiving conveyor 3, was lowered, and the elevator 28 was moved downward.
Tap member 285 passes the origin limit switch 17 and hits the switch member of the origin return limit switch 18 to temporarily stop at a position lower than the receiving height.
Thereafter, the elevator 28 rises to the receiving height and stops as described above. Thus, in both cases,
When the height of the receiving conveyor 3 is set to the receiving height, the lifting member 28 is raised and the tap member 285 of the lifting table 28 stops when the switch of the origin limit switch 17 is hit. Therefore, the influence of inertia due to the weight when descending is small, and the vehicle can be stopped at an almost accurate height.

That is, the lifting device 2 is stopped by a brake (not shown) in order to reduce the shock at the time of stopping. However, in this structure, there is a great difference in the load on the brake between the case where the elevating unit such as the elevating table 28 is lowered and stopped and the case where it is lifted and stopped. That is, in the case of stopping by lowering, the inertia force is increased because the moving direction overlaps with the direction of attraction, so that the braking distance is long and the distance is hard to be uniform. On the other hand, in the case of raising and stopping, the moving direction is the direction of the repulsive force, so that the weight of the elevating portion is offset and the inertia force is reduced, so that the braking distance is short and uniform. In other words, if the receiving conveyor 3 is lowered and temporarily stopped at a position lower than the receiving height, and then raised to the receiving height and stopped, it can be stopped almost exactly at a preset height.

The terms and expressions used in the present specification are for explanation only, are not restrictive, and do not exclude the terms and expressions equivalent to the above-mentioned terms and expressions. Further, the present invention is not limited to the illustrated embodiment, and various modifications are possible within the scope of the claims.

[0038]

The present invention has the above configuration and has the following effects. (A) In the shelving apparatus according to the first aspect, the goods conveyed by the conveyor are received by the receiving conveyor, the receiving conveyor is raised and lowered by the elevating device, and the receiving conveyor is stopped by the stop height control means. The height can be controlled, and the conveyed material can be sent out from the receiving conveyer to the shelf and stored by the sending device. This allows, for example,
In furniture manufacturing, the operation of transferring a carrier plate on which furniture parts are arranged at the top from a conveyor to a shelf can be mechanized. Therefore, the work efficiency is improved, and the cost balance between profit and maintenance cost in the long term can be improved.

(B) In the shelving device according to the second aspect, the delivery device includes a circulating chain and a plurality of locking members provided on the circulating chain. By the circumferential movement of the chain, the locking body on the feed drive side of the circumferential chain is locked to the conveyed object and sent out at a predetermined feed length, and after the sending is completed, the next locked body is driven to feed the circumferential chain. The air cylinder, which has a long stroke length and is expensive, should be extended by extending the chain, especially when setting the feed length to be long. It can be manufactured at a lower cost as compared with the case where a driving source is used. In addition, if the peripheral chain is used, the speed of the delivery can be easily adjusted by controlling the number of rotations of the sprocket. Therefore, when a non-fixed object is included in the conveyed object, the speed can be adjusted so that the non-fixed object does not drop due to sudden movement.

(C) In the shelving apparatus according to the third aspect, a delivery member for receiving the conveyed article is provided at a front portion of the receiving conveyor, and the delivery member moves forward and backward with a predetermined length in the front-rear direction. In order to send out a conveyed product, a forward / backward transfer device that receives the conveyed product at the position moved to the shelf truck side is provided. The shelf cart can be placed at a position farther from the shelf device. As a result, a space around the shelving device can be provided and various accompanying operations can be easily performed.

(D) In the shelving apparatus according to the fourth aspect, the stop height control means sets the receiving conveyor to the receiving height when the previous stopping height was higher than the receiving height. Is designed to lower the receiving conveyor and temporarily stop it at a position lower than the receiving height, then raise it to the receiving height and stop it, so that it can be stopped at an almost accurate height with little error. That is, the lifting device is generally stopped by a brake in order to reduce the impact at the time of stopping. However, in this structure, there is a great difference in the load applied to the brake between the case where the lifting unit is lowered and stopped and the case where it is raised and stopped. That is, in the case of stopping by lowering, the inertia force is increased because the moving direction overlaps with the direction of attraction, so that the braking distance is long and the distance is hard to be uniform. On the other hand, in the case of raising and stopping, the moving direction is the direction of the repulsive force, so that the weight of the elevating portion is offset and the inertia force is reduced, so that the braking distance is short and uniform. In this way, if the receiving conveyor is lowered and temporarily stopped at a position lower than the receiving height, and then raised to the receiving height and stopped, it can be stopped almost exactly at a preset height.

(E) In the shelving method according to the fifth aspect, the conveyed goods are received by the receiving conveyer, and the receiving conveyer on which the conveyed goods are loaded is raised or lowered to match the height of the empty shelf of the shelf cart. The conveyor is pushed out to the shelf truck side by a predetermined length and brought close to it, and the conveyed goods are sent out and transferred to the empty shelf of the shelf truck. Since it can be moved to the side by a predetermined length, the shelf cart can be arranged at a position further away from the shelving device as compared with a structure in which delivery is performed only by the delivery device. As a result, a space around the shelving device can be provided and various accompanying operations can be easily performed.

(F) In the method for setting the receiving conveyor to the receiving height in the shelving apparatus according to the sixth aspect, when the receiving conveyor is set to the receiving height, the last stop height of the receiving conveyor. Is higher than the receiving height, the receiving conveyor is lowered, temporarily stopped at a position lower than the receiving height, and then raised to the receiving height and stopped. Therefore, for the same reason as in the fourth invention, It can be stopped at an almost accurate height with little error.
