Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is attached to a vertical rotating storage so that containers containing articles can be automatically inserted into the rotating storage or outside. The present invention relates to a warehousing/retrieval device capable of warehousing.

[Conventional technology]

As disclosed in, for example, Japanese Unexamined Patent Publication No. 63-230409, a vertical rotating storage is constructed by winding an endless chain around sprockets provided on a pair of upper and lower horizontal shafts. , by installing a large number of trays on which containers containing goods are placed, and by running the endless chain at the same time,
Each tray is designed to rotate in a long elliptical trajectory around a horizontal axis. In such a vertical rotating storage, a pusher that can reciprocate horizontally is provided at an appropriate position in the turning path of the tray, and pushes any container that arrives at the take-out window from the tray to the receiving shelf. It is made to be moist. [Problems to be Solved by the Invention] In the above-mentioned conventional product, the unloading operation of pushing the container out of the tray and the reloading operation of returning the container to the original tray after taking out the articles in the container are performed through a single ejection window. In addition, storage was done manually, so the work of taking out a large number of containers from multiple rows of rotating storage and returning them to their original trays was complicated and took too much time.

Furthermore, if the previous container is pushed out onto the receiving shelf, the next container cannot be taken out consecutively, so the previous container must be returned to its original tray, resulting in poor work efficiency.

The present invention has been made in order to solve the above problems, and is a vertical storage system that greatly improves work efficiency by automatically and continuously carrying out the loading and unloading of containers without human intervention. The object of the present invention is to provide an automatic loading/unloading device for a mold rotation storage.

[Means to solve the problem]

A vertical rotating storage that allows multiple trays to be rotated vertically is provided with window holes for entry and exit at the top and bottom of the front. A conveyor for lateral feeding is provided, and a pushing device is provided at the rear of the tray facing either the upper or lower window hole to push out the load stored in the tray from the window hole onto the conveyor in front of the tray,
In addition, a pushing device is provided in front of the other window hole to push the load sent by the conveyor through the window hole into a tray facing the window hole.

In addition, the invention as claimed in claim (2) further provides the structure of the invention as claimed in claim (1) above, by further connecting each end of the upper and lower conveyors to the upper and lower entrances and exits of the lifting device. It is characterized by the addition of a configuration in which a conveyance path is formed from one window hole to the other window hole via both conveyors and a lifting device. [Function] Of the upper and lower window holes, the one with the extrusion device installed behind the tray is used for taking out the tray, and the one with the extrusion device installed in front of the window hole is used for warehousing.When the extrusion device for unloading is activated, , containers and other loads in the tray are pushed through the window hole and onto the conveyor in front of it. There, the necessary picking operations are performed from the containers, etc., and after that, the conveyor is operated to transport the containers and other cargo from the front of the window hole to the side. Next, the desired tray will face the exit window. After rotating the sea urchin tray, in the same way as above, the extrusion device is operated to take out the next container or other cargo through the window hole, and after performing picking operations, the conveyor is operated,
Transport containers, etc. horizontally.

In this way, on the unloading side, desired loads can be taken out one after another in rapid succession.

In addition, at the warehousing window hole, after the desired container or other cargo is conveyed to the front of the window hole by the warehousing conveyor, the conveyor is stopped, and then the warehousing extrusion device is activated. The container or the like can be pushed through the storage window and into the empty tray behind it.

Next, using the free time on the exit side, the trays are rotated to position the desired empty tray behind the entry window, and then the trays sent by the conveyor are placed in the same manner as above. A container or the like is pushed into an empty tray through a window hole by a pushing device.

In this way, on the warehousing side, the goods sent from the conveyor can be quickly stored in the storage one after another by utilizing the empty time on the outgoing side.
