Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a storage facility comprising a combination of a storage shelf device and a transport device for loading and unloading.

When the storage shelving device is equipped with a large number of cargo receiving parts divided horizontally and horizontally and vertically and vertically, conventionally, the goods are transported to the storage shelf device by an appropriate conveyance means such as a floor conveyor or a trolley conveyor. The loaded cargo is transferred to a special loading/unloading device, such as a stacker crane, which is equipped with load supporting parts that can correspond to all the load receiving sections of the storage shelving device, or by this loading/unloading device. The structure is such that the loaded cargo is transferred to the above-mentioned suitable conveyance means and carried out to the required location.

That is, in conventional storage facilities, there is no connection between the transportation means for loading cargo into the storage facility or the transportation means for unloading cargo from the storage facility and a special loading/unloading device such as a stacker crane that the storage facility is equipped with. The efficiency of loading and unloading work is greatly improved by requiring loading and unloading work and by requiring the stacker crane, etc. to return to its home position after loading and unloading one load. I couldn't do it.

In addition, as a method that does not use the above-mentioned stacker crane, for example, as described in Japanese Patent Application Laid-open No. 50-48678, there is a
Storage equipment is also known in which trolley conveyor type transport devices are arranged side by side and loads are transferred between the storage shelf device and the hanger of each transport movable body in the transport device. In this storage device, the transportation moving body was configured to move horizontally at a constant level on the side of the storage shelf device, so that the moving path of the transportation vehicle and the storage shelf device were This requires an elevating and lowering transfer device that can be moved up and down between the storage racks and that spans the entire length of the storage shelf device, resulting in a very complicated and expensive equipment structure.

The present invention aims to provide a storage facility that can solve these problems, and one embodiment thereof will be described below with reference to the attached illustrative drawings.

Reference numeral 1 denotes a storage shelf device formed by stacking rotating shelves 2a to 2d in a plurality of upper and lower stages, in which each level of rotating shelves 2a to 2
d is a drive chain 6 suspended between a drive wheel 4 driven by a drive motor 3 and an idler wheel 5;
and a large number of trays 7 connected to the drive chain 6 at equal intervals and rotating in a horizontal circulation path. Reference numeral 8 denotes a conveyance device disposed so as to pass through one side of the storage shelf device 1, which includes one guide rail 9, a conveyance moving body movably supported by this guide rail 9, and 10. It consists of
The transport vehicle 10 includes a self-propelled cart 11, a free cart 12, a connecting rod 13 whose front and rear ends are connected to the lower ends of both carts 11 and 12, and a horizontal support shaft in the center of the connecting rod 13. The self-propelled trolley 11 is composed of a hanger 15 that is suspended through a hanger 14 so as to be swingable back and forth. and a motor 18 that is driven via a power supply rail and a control signal transfer rail group 19 supported on the side of the guide rail 9 through a current collecting means 20. It runs automatically. Reference numeral 21 denotes a vertical axis roller for steadying, which sandwiches the lower end of the guide rail 9 from the left and right sides. The free truck 12 has an idler wheel 22 that fits on the guide rail 9, and a roller 23 that is the same as the vertical axis roller 21 for steadying of the self-propelled truck 11.

The guide rail 9 has an inclined portion 9a on one side of the storage shelf device 1. Due to the presence of this inclined guide rail portion 9a, the conveyance moving body 10
The moving hanger 15 travels diagonally upward (or diagonally downward) on the side of the storage shelf device 1, and the difference in height of the traveling route is such that the moving hanger 15
It includes the range from the height corresponding to the tray 7 of the lowest rotary shelf 2a to the height corresponding to the tray 7 of the highest rotary shelf 2d. Therefore, hanger 1
5 is the loading/unloading position A corresponding to the tray 7 of the bottom carousel 2a, and the hanger 15 is the second carousel 2b.
Loading/unloading position B, hanger 1 corresponding to tray 7
5 corresponds to the tray 7 of the third carousel 2c, and the hanger 15 corresponds to the tray 7 of the top carousel 2d at the loading/unloading position D. 10 can be stopped.

In addition, each tray 7 of the storage shelf device 1 is open at the side adjacent to the hanger 15 of the conveyance movable body 10, and the side adjacent to the hanger 15 of the conveyance movable body 10 is open.
The side adjacent to the tray 7 and the opposite side thereof are open, and the load 24 can be transferred between the tray 7 and the hanger 15 in a state in which they are aligned side by side. has been done.

Next, to explain how to use it, when the object of loading/unloading work is the tray 7 on the lowest carousel 2a, move the transporting moving body 10 of the conveying device 8 to the loading/unloading position A with respect to the carousel 2a. While stopping at this position, the drive chain 6 is rotated by the drive motor 3 of the rotary shelf 2a to move the tray 7 to be loaded and unloaded.
corresponds to the loading/unloading position A. As a result, the tray 7 to be loaded and unloaded from the carousel 2a and the hanger 15 of the conveying vehicle 10 are adjacent to each other, and the load 24 can be transferred between them, so that appropriate load transfer can be carried out. Loading means, for example, as shown by the imaginary line in FIG. The loading/unloading operation can be performed by the loading/unloading device 26 which pushes the load 24 on the hanger 15 onto the tray 7 of the carousel from the outside. Similarly, when loading/unloading the tray 7 of the second-stage carousel 2b, the conveyance moving body 10 is stopped at the loading/unloading position B, while the tray 7 of the carousel 2b is rotated to load/unload the tray 7. The target tray 7 is made to correspond to the loading/unloading position B. Further, the conveyance moving body 10 is stopped at the loading/unloading position C or D, and the tray 7 of the rotating shelf 2c or 2d is rotated to make the tray 7 to be loaded/unloaded correspond to the loading/unloading position C or D. By doing so, the trays 7 belonging to the third carousel 2c and the top carousel 2d can be loaded and unloaded.

Of course, the conveyance moving body 10 is used as a conveyance means for conveying the load 24 to be stored from a required location to the storage shelf device 1, and also as a conveyance means for conveying the load 24 taken out from the storage shelf device 1 to the required location. It can be used as.

The storage shelf device 1 includes rotating shelves 2a to 2d at each stage.
They may be integrated so that they cannot be rotated individually. However, as shown in the embodiment, when the rotating shelves 2a to 2d of each stage are configured to be able to be rotated individually, the loading/unloading positions A to D
All of the plurality of loading/unloading positions where the transporting moving body 10 can be stopped at the same time (in the illustrated example, the transporting moving body 10 can be stopped at all the loading/unloading positions A to D at the same time), Alternatively, by stopping the conveying movable bodies 10 at a plurality of arbitrary positions, the above-mentioned loading/unloading operations can be performed simultaneously on the plurality of rotating shelves 2a to 2d.

The hanger 15 of the conveyance moving body 10 is attached to the support shaft 1 at least when the hanger 15 is stopped at each loading/unloading position A to D.
It is desirable that the structure is such that it does not swing back and forth around 4. For this reason, when the transportation moving body 10 is guided by the inclined guide rail portion 9a, for example, as shown by the imaginary line in FIG.
A guide rail 28 that prevents the hanger 15 from swinging back and forth can be constructed via a guide roller 27 pivotally supported by the hanger 15.

The storage facility of the present invention can be implemented as described above, and includes a plurality of stacked upper and lower rotating shelves equipped with a large number of load receiving parts (trays 7 in the embodiment) that can rotate in a horizontal circulation path. It consists of a combination of a storage shelf device consisting of a storage shelf device and a conveyance device disposed so as to pass through the side of the storage shelf device, and this conveyance device transfers goods to and from the cargo receiving section of the storage shelf device. It has a plurality of conveyance movable bodies equipped with a load support part [hanger 15 in the embodiment] that can maintain a horizontal posture even on a vertically inclined conveyance path, and these conveyance movable bodies The moving path on the side of the storage shelf device is such that the load support portion of the conveying moving body is inclined from a position corresponding to the lowest rotating shelf to a position corresponding to the highest rotating shelf. stopping the conveying moving body at a position where its load supporting portion corresponds to the height of the rotating shelf of the stage to which the loading/unloading target loading/unloading receiving section of the storage shelf apparatus belongs;
By rotating the rotary shelf so that the cargo receiving section to be loaded and unloaded corresponds to the cargo support section of the transporting vehicle, the incoming cargo transported by the transporting vehicle is placed in the storage shelf device. It is possible to store the cargo in any cargo receiving section, or to take out the cargo stored in any cargo receiving section in the storage shelf device to the transporting moving body. Moreover, there is no need for a stacker crane, etc., dedicated to loading and unloading, which is used in conventional automated warehouses. It is possible to use the trolley conveyor, cart type conveyor, etc. that are used as is, and simply tilt a part of the movement path of the transport device as described above to move the transport vehicle at the required height. Since it is only necessary to configure the transport device so that it can be stopped, this transport device can be used as is as means for transporting goods to the storage shelf device or as means for transporting goods taken out of the warehouse. Therefore, it is possible to eliminate the work of transferring loads between a stacker crane or the like dedicated for loading and unloading and the means for conveying loads to the storage shelf apparatus, or the means for conveying unloaded loads.

Further, since the loading and unloading operations can be performed simultaneously or sequentially using a plurality of conveyance vehicles that move in the same direction, the efficiency of the entire loading and unloading operations can be greatly improved.

It should be noted that each transporting body in the transporting device has a load receiving part of the storage shelf device (tray 7 in the embodiment) and a load supporting part of the transporting body (hanger 1 in the embodiment).
5) It is also possible to provide a load transfer means for transferring loads between.
