BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article conveying and accommodating apparatus for accommodating a large number of articles in and out of a warehouse or other physical distribution facility.

[0002]

2. Description of the Related Art Conventionally, as a device for handling, transporting, and storing a large number of articles in a distribution facility such as a warehouse or a distribution center, there is a carry-in / out port, and a guide rail gently inclined from a transport start end side to an end side. There is known a transfer / accommodation device including a flow rack having a fluidized shelf. As the transport and storage device, a rack installed in a physical distribution facility in a plane direction and a height direction is provided with an inclined guide rail in which a large number of rollers are rotatably attached to form a fluidized shelf. When the pallet on which the article is placed is placed on the guide rail from the storage entrance by hand or a forklift, etc., the bottom of the article or pallet slides while rotating the rollers, and the guide rail is inclined to reach the end of conveyance, and the stopper It came into contact with the mechanism and stopped.

[0003]

However, in this conventional article transporting and accommodating apparatus with a fluidized shelf, the article loading port side of the loading side end and the loading port side of the loading side end are fixed, and one side Since the goods are handled by flowing from one side to the other side,
Forklift passages are provided on both sides, and for the movement of the forklift, the warehousing work moves to the goods storage port at the end on the loading side,
Also, the unloading work had to be moved to the end on the unloading side. There is no problem if the items or pallets are arranged and stored in order, but if they are delivered in order,
If it becomes necessary to pick up a part of the parcels out of order, pick up the parcels in order from the one closest to the carry-out port, and repeat the process until the target parcel is picked up. There was the inconvenience of having to stack the luggage that had been taken out in the aisle and place it in the aisle, and to store it again by using a forklift at the carry-in side. Therefore, each time the forklift is moved around the rack, it takes a long distance and takes a long time,
It was complicated and the workability was poor. In order to solve this, usually, the center of the rack or the like is appropriately divided to provide a dedicated forklift travel passage, but there is a vicious circle that storage efficiency is reduced by that much, which is a problem. The present invention properly eliminates these conventional drawbacks, and the management of goods may be last-in, first-out, that is, the preparation of the assortment for shipping has already been completed in advance, and the delivery vehicle is waiting for arrival and loading. For temporary storage of goods for storage, goods that are shipped together in a specified short-term storage, and goods that have no problem even after the first-in / first-out, the forklift does not have to rotate around the rack each time the work of both loading and unloading is performed. It is an object of the present invention to provide an article transporting / accommodating apparatus capable of significantly improving workability by allowing work in one direction and improving article storage efficiency without requiring a forklift passage in one direction.

[0004]

According to the present invention, a frame having a plurality of vertical and horizontal article transport lanes has a loading port and a loading port for an article or a pallet on which the article is placed, and a large number of rollers are rotatable. In the article transporting and accommodating apparatus provided with the flow rack arranged in a slanting direction so that the flow racks are inclined in the opposite direction in the vertical direction, the flow racks are provided with receiving plates for mounting the articles or pallets on both sides of the carry-in port and the carry-out port.

It is a storage device.

[0005]

The pallet P on which the article W on the loading support plate 3 on the lifter 4 is placed from the carry-in entrance A on one side of the frame is placed on the conveyance start end of the gently inclined guide rail, and then the pallet P is succeeded next. When is pushed in, the preceding pallet slides on the roller 1 while rotating the roller of the guide rail, and is accommodated in series on the guide rail of the flow rack 2 and mounted on the support plate 3 at the lifter 4 ₁ at the end of conveyance. Put on ₁ ,
It is stopped by a stopper mechanism 5 such as an impact plate and a protrusion provided on the mounting receiving plate 3 ₁ . When the upper and lower flow racks 2 and 2 are used as a pair, the lifter 4 ₁
After moving up to the article transport lane immediately above, the loading support plate 3 ₁ is tilted in the opposite direction and the pallet P is slid on the flow rack 2 at a gentle slope, and the lane above the carry-in entrance A is the carry-out exit. Then, it will be carried out from here. Further, when returning to the lower lane, the loading support plate 3 of the lifter 4 may be lowered to swing and tilt in the opposite direction, and the article W may be loaded onto the flow rack 2. Therefore, in the case of out-of-order or picking a necessary article, the sequentially fed pallet P may be circulated and transferred in the upper and lower lanes so that the desired article comes out and is moved in and out until the desired article comes to the carry-out position. In this case, even if the carry-in port A and the carry-out port B are on the same side for carrying in and out, one side is also carrying out the carry-out port B.
Also in such a case, necessary articles can be carried out by feeding in and out in the upper and lower lanes and circulatingly transferring. At the time of unloading, the pallet P is smoothly pushed out at a gentle slope by overcoming or removing the stopper mechanism 9 provided on the unloading port B side, and the pallets P are sequentially unloaded from here. While the goods are being unloaded at the goods outlet group side, preparations for assortment for shipping have already been completed in advance, and temporary storage goods for waiting for arrival and loading of the delivery vehicle, and storage for a specified short period of time. Regarding the storage of items that are shipped all at once, and items that can be sent in and out without problems, the work of both loading and unloading can be done in one direction without the forklift rotating around the rack each time, and mistakenly Even when it is necessary to exchange items such as taking out items or returning extra items, by loading and unloading at the same item loading / unloading port, items can be automatically switched between loading and unloading. It is stored in the first-in, first-out position, and there is no need to transport the forklift one by one to move the goods in and out at the same place, greatly improving the work efficiency and effectively using the storage area. That.
