CONSTITUTION:A plate 18 is loaded on a base 17 and raised to slightly lift up all pallets 3 in a pallet storing portion 2A on descent side and release stop portions 4A, 5A. After that, the base 17 is lowered for one pallet 3 and the stop portions are again operated. In such a condition, the base 17 is further lowered a little so that with the second and upper pallets 3 from the bottom left in the storing portion 2A, only the lowermost pallet 3 is transferred onto a rotary belt 19, and moved with the plate 18 below a storing portion 2B and stopped. At this time, an upper crossfeed device 10 is operated to crossfeed the upper pallet 3 in the storing portion 2B to the upper space in the storing portion 2A and to make space in the upper part of the storing portion 2B, and the base is again raised to lift up the pallet 3 and push a pallet in the lower part of the storing portion 2B. Subsequently, the whole is raised to stop the uppermost pallet 3 with a stop portion 4B. Thus, a lot of pallets are circulated to automatically and quickly transfer products.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a portable, small-sized automatic warehouse for storing arbitrary products on pallets in various factories and transporting and connecting various manufacturing and processing lines.

In order to automate the manufacturing and processing of small products in various factories, etc., it is necessary to transport the products between various manufacturing and processing lines in an automatically organized and regulated state.

Generally speaking, this transportation system is such that a large number of pallets containing small products are first loaded onto a trolley and transported, and then the pallets are unloaded again at the next manufacturing/processing department. Loading and unloading IC requires a lot of work, and it is difficult to organize and control a large number of pallets for loading and unloading. Therefore, in the next manufacturing and processing department, the pallets are positioned and set, and It is necessary to control the positioning according to the pallet, and this positioning control also requires a lot of effort.

However, according to the conventional system, when transporting products using pallets, there are many difficulties in transporting the pallets, that is, the products in an organized and regulated state. In order to partially solve this drawback, there is a vertical conveyor device disclosed in Japanese Patent Application Laid-Open No. 57-137230, but although it is possible to stack pallets once and manage the product for a period of time, it is not possible to transfer between each line. When it comes to linking, it's still automated and has problems.

The present invention has been made in view of the above points, and is an automatic system that stores various products on pallets and transfers them between manufacturing and processing lines. By making it possible to directly load and unload products onto and from the pallets, there is no need to load and unload the pallets themselves, and the above-mentioned small warehouse can be , □We propose a small portable automatic warehouse that can completely and efficiently automate the transfer of products between lines using pallets.

Then, the entire loaded pallet 3.3 is raised one step at a time, and the uppermost pallet 3 is received by the receiving portion 4B. At this time, since the receiving parts 4B and 5B are formed as shown in FIG. 5, they are automatically released from and automatically locked to the recessed part 22 of the pallet 3. Become.

Note that the above-mentioned receiving portions 4A, 5A and receiving portions 4B, 5B may each have the same form, or may have other configurations. On the other hand, although the cross-feeding device 10 has a pressing structure, it can also have a traction structure.

Further, the transfer device 11 can also be constructed by using the lifting device 12 and the lateral movement device 13 as an integrated mechanism.

Next, the operation of the automatic warehouse of this embodiment described above will be explained. In the state shown in FIG. 1, the workpiece loading robot 30 loads arbitrary products from the entrance/exit section 7 onto the upper pallet 3 of the two pallet storage sections. Then, the lower pallets 3 of the two people from one pallet storage section are taken out by the lifting device 12, and then the upper pallets 3 of the other pallet storage section 2B are taken out by the lateral transport υ device 10 from the empty pallet storage section 2. The pallet 3 is transported horizontally to the upper part of the person, and finally the pallet 3 taken out is transferred to the other knot storage section 2 by the lifting device 12 and the horizontal moving device 13.
The pallet 3 is loaded into the lower part of B, and the first stage of the pallet 3 circulation feeding system is completed.

By performing this operation continuously, all of the pallets 3 are loaded with products. When the work of loading products onto the pallet 3 is completed, the frame body 1 is moved to the next product manufacturing/processing line, where the products are taken out from each pallet 3 by the same operation as above, and all work between the series of lines is completed. That will happen. Connections between the lines mentioned above can be made not only within the same building, but also between outside subcontractors, etc., and between the lines can also be used as a warehouse for a predetermined period of time.

As described above, the present invention is configured so that the pallet is automatically circulated within the frame body when loading the workpieces onto the pallet, thereby eliminating the need for a pallet control robot in the workpiece loading section. can be transported directly to the next line, eliminating the need for a pallet control robot in the workpiece loading/unloading section.Furthermore, each pallet is regulated and circulated within the frame body, allowing accurate positioning and organization. management can be performed extremely easily and quickly. Therefore, according to the present invention, it is possible to manage the transfer of products in a state in which the products are arranged on pallets, and also to efficiently transfer between each line in a state in which a large number of pallets can be circulated. This has the effect that it can also be used as a warehouse for a certain period of time during line transfer.
