Description

[Detailed description of the invention] Industrial application field This invention is a horizontal storage system suitable for storing goods used or handled in factories, warehouses, etc., and transporting them to production processes, etc., or shipping them as necessary. Concerning improvements to circulating storage shelf equipment.

Prior Art There are various types of horizontal circulating storage shelves of this kind, as seen in Utility Model Application No. 73328/1983, No. 120505/1983, and 30606/1988. As shown in Fig. 1, the circulating storage shelves are arranged by attaching a plurality of storage shelves 2 to the outside of an endless rotating body 1 that is stretched between a driving sprocket A and a driven sprocket B. It was common to have a plurality of horizontal circulation type storage devices 3 of the same length installed almost horizontally. The loading and unloading device is provided with a belt conveyor 4 for loading and unloading at the end of the horizontal circulation storage device 3 on the driving sprocket A side so as to be on an extension line of the horizontal circulation storage device 3. In addition, a sorting conveyor 5 is further provided at the other end of the belt conveyor 4, and the articles are loaded and unloaded while being sorted.

In this way, the loading/unloading device is connected to drive sprocket A.
The reason why the driven sprocket B is placed on the side is that in many cases, the driven sprocket B is on the take-up side to absorb the slack of an endless body such as a chain, so the position of the sprocket changes, so it is not necessary to provide a loading/unloading device. This is because it is inappropriate.

Therefore, in many cases, loading and unloading was performed only at one end. In this way, if loading and unloading is performed only at one end,
A great inconvenience occurs when a factory is laid out so that goods flow from one side and flow to the other. Furthermore, there may be cases where it is desired to carry out warehousing and warehousing at separate locations. In addition, in storage areas where space is relatively small, lining up the horizontal circulation storage device 3, belt conveyor 4, and sorting conveyor 5 in series may be too long or make it difficult to transfer to the next process. It was hot too.

Purpose of the invention The present invention is intended to provide a horizontal circulating storage shelf facility that allows storage and removal at both ends and enables convenient use of the storage space depending on the size of the storage space.

Structure of the invention The horizontal circulation type storage shelf equipment of the present invention includes a plurality of storage shelves in an endless body, a plurality of horizontal circulation type storage devices for horizontally circulating the storage shelves, and a horizontal circulation type storage device for horizontally circulating the storage shelves. are installed almost parallel to each other,
At one end of the horizontal circulation storage device, the length of the horizontal circulation storage device is gradually shortened, and a storage entry or exit or storage entry/exit device is provided in a direction orthogonal to the end. have

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 2 shows an embodiment of the present invention, in which the length of the horizontal circulation storage devices 3 is gradually changed at the end of the driven sprocket B side of the horizontal circulation storage devices 3 installed almost in parallel. The storage shelf 2A on the side of this one end is opened so that objects to be stored in the storage shelf 2A can be taken in and taken out. In addition, a horizontal circulation type storage device 3 is installed adjacent to the open storage shelf 2A.
In a direction substantially perpendicular to the , a storage/unloading or loading/unloading device consisting of a belt conveyor 6 as a transfer device is provided. The lengths of the belt conveyors 6 connected to the horizontal circulation storage devices 3, which have stepwise lengths, also differ stepwise. Furthermore, a sorting conveyor or the like may be connected to the belt conveyor 6.

On the drive sprocket A side, a supply belt conveyor 7 is arranged at the end of each horizontal circulation storage device 3 in the longitudinal direction of the horizontal circulation storage device 3.
These belt conveyors 6 and 7 perform supply and discharge at a position where the conveyor surface and storage shelf 2 are parallel.

FIG. 3 shows another embodiment of the present invention.
The length of the horizontal circulation type storage device 3 on the drive sprocket A side of the horizontal circulation type storage device 3 is also shortened in stages, and the storage shelf 2B on the side of this part is opened,
A discharge belt conveyor 7 is provided adjacent to the storage shelf 2B in a direction substantially perpendicular to the horizontal circulation type storage device 3.

In the embodiments described above, the belt conveyors 6 and 7 may be replaced by other conveying devices, such as conveying forks or pushers, and the storage shelves and loading and unloading devices may be provided in multiple stages.

Effects of the invention According to the present invention, in order to absorb the slack of the endless body of the horizontal circulation storage device, even if the sprocket of the endless body moves slightly, the relative distance between the loading/unloading device and the endless body does not change. Therefore, the transfer device for retrieving stored items can be placed on the driven side of the horizontal circulation storage device, and storage and unloading can be done on separate sides of the horizontal circulation storage device, reducing the confusion of stored items. The cycle time for receiving and unloading is shortened, and there is greater freedom in the arrangement of warehousing, storage, and unloading. Sufficient space can be used even in short storage areas, and the present invention can be used in combination with large storage areas. In the same way, it can be used without waste, and if a transfer device is connected, it can be transported to the next process over a short distance. In addition, by moving the endless rotating bodies of the parallel horizontal circulation storage devices as necessary, desired stored items can be efficiently taken out, which is very convenient.
