Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for storing articles that do not like dirt.

In general, shelves for three-dimensionally storing articles include sheet-type shelves in which shelf boards are arranged in multiple tiers, and drive-in type tanks in which members for supporting both ends of articles are arranged in multiple tiers.

However, for storage shelves where goods are loaded and unloaded using a stacker crane, drive-in tanks are often used, which allow the crane to have a large error in stopping accuracy in the vertical direction, and which also allow for narrow vertical shelf spacing. There is.

In the above-mentioned drive-in tank, dust, oil, rust, etc. fall from the bottom or side of the pallet placed on the upper tier and adhere to the items on the lower tier while the items are being carried in or out or stored on the shelves. do.

Therefore, when storing items that are sensitive to dirt, such as storing products before packaging and cartoning in the textile industry and temporarily storing them between processes, or storing intermediate raw materials in a three-dimensional refrigerator in the food industry, and even when storing products for photographic film. When storing photosensitizers in storage warehouses, it is necessary to take some preventive measures.

Therefore, partition plates are installed between each shelf to prevent dirt from falling, or workers attach covers to each item to prevent dirt from falling.

However, in the case of a shelf like the one shown in Fig. 2 in which the former partition plate is installed between the shelves, the height of one shelf hl, the height d of the applicable article A, the thickness C of the fork 3 of the stacker crane, and the loading and unloading of article A are determined. The dimension a required to lift the article above the support 2 in order to place the article on the support 2, and the dimension required to lower the fork 3 to place the article A on the support 2, the manufacturing error of the shelf and the fork It is the sum of the margin dimensions α that take into account the movement error etc. of 3.

On the other hand, in a drive-in type tank without a partition plate as shown in Fig. 1, the forks 3 can move vertically between the supports 2, so the height hs of one shelf is smaller than that of the goods. Either the height d, the thickness C of the fork 3 of the stacker crane, the dimension a necessary to lift the article A, and the allowance dimension α, or the height d of the article A and the stacker crane The thickness C of the fork 3 and the thickness of the fork 3
The dimension required to lower the dimension is the larger of the sum of the margin dimension α and the dimension α.

Therefore, the shelf spacing of the shelves with partition plates is larger by the smaller of the dimension a required to lift the item A or the dimension A required to lower the fork 3. Overall storage efficiency deteriorates.

Also, in the latter method, the worker attaches the cover to the item, so
There were drawbacks such as an increase in extra steps and a decrease in work efficiency.

The present invention was obtained as a result of studies aimed at solving the drawbacks of the above-mentioned article storage methods.

That is, the present invention includes a shelf that supports and stores both ends of an article;
In a three-dimensional storage shelf consisting of a stacker crane that moves vertically and horizontally along the shelf to load and unload articles, and a loading/unloading station installed at the end of the shelf, a cover holding leg is attached to the loading/unloading station. When carrying in goods, the pallet on which the goods are placed is raised between the holding legs and from below the cover, and the cover is lifted from the holding legs by the goods, so that the cover is attached to the goods, and when carrying out the pallet, the pallet is lifted up from below the cover. A method for storing articles in which a cover attached to an article is held on the retaining legs by lowering the cover between the retaining legs and from above the retaining legs, and removing the cover prevents dirt from adhering to the article. It provides:

Here, the articles include textile products such as full bobbins and empty bobbins, as well as articles that do not like stains, such as foods or photosensitizers in photographic films.

At least one loading/unloading station may be installed on the storage shelf, and a mechanism for positioning articles at a predetermined position on the cover holding legs may be installed.

A pallet for placing and storing articles may be a disk-shaped object, a box, a disk-shaped object with protruding supports, etc., depending on the shape of the object.

The cover holding legs are constructed with protruding pillars, or are constructed with support members equipped with a mechanism for moving movable claws in and out.

A schematic plan view of a three-dimensional storage shelf for implementing the present invention is shown in the third figure.
A schematic front view is shown in FIG. 4, and its configuration will be explained below.

11 is a loading/unloading conveyor station equipped with cover holding legs 10, and 12 is a stacker crane having a fork 16 for scooping up articles from below.

13 is a storage shelf with an article support member attached to a support;
Reference numeral 4 denotes a loading/unloading conveyor station on which cover holding legs 10 are installed.

15 is a conveyor formed in a loop shape.

In the three-dimensional storage shelf configured as described above, the loading/unloading conveyor station 11 carries in full bobbins from the production process and carries out empty bobbins.

On the other hand, the loading/unloading conveyor station 14 side is full bobbin A.
The system is such that the bobbin A' is carried out onto a conveyor 15, and an empty bobbin A' is carried in from the conveyor.

Based on the cover attachment operation diagrams in Figures 3, 4 and 5,
The drawer's actions for goods will be explained.

First, the cover B is placed on the cover holding legs 10.

Next, the pallet on which the fully wound bobbin A is placed is conveyed from the production process to the loading/unloading conveyor station 11.

The pallet supplied to the station 11 is automatically positioned at a predetermined position between the cover holding legs 10 by guides, rolls, etc. installed at the station.

When this operation is completed, the stacker crane 12 moves to the receiving position of the loading/unloading conveyor station 11, protrudes the fork 16 in the Y direction, and inserts it under the pallet.
Lift it upwards in this position.

At this time, the lever B is pushed up at the upper end of the fully wound bobbin A and removed from the cover holding leg 10, and the cover B is mounted on the fully wound bobbin A.

The fork 16 is retracted in the X direction in the state shown by the chain line, and in this state the stacker crane 12 moves and reaches the predetermined shelf 13.

When the loading operation is completed, the stacker crane 1
2 is moved to the shelf where the pallet on which the empty bobbin A' is placed is stored, and the pallet is held by the fork 16 and conveyed to the loading/unloading conveyor station 11 and unloaded between the cover holding legs 10.

The cover B mounted on the space-time bobbin A' is held by the cover holding legs 10 and removed, and the empty bobbin A' is transported to the production process.

On the other hand, the fully wound bobbin A stored on the shelf is taken out by the stacker crane 12 for inspection and packaging, transported to the loading/unloading conveyor station 14, and unloaded between the cover holding legs 10.

At this time, the cover B mounted on the fully wound bobbin A is held by the cover holding legs 10 and removed.

The fully wound bobbin A is transferred to the transport conveyor 15 and transported to an inspection and packaging process.

The newly prepared empty bobbin A' is transported by the transport conveyor 15 and transferred to the loading/unloading conveyor station 14, where it is automatically positioned between the cover holding legs 10 by guides, rolls, etc. installed at the station. .

When this operation is completed, the stacker crane 12 moves to a predetermined position, protrudes the fork 16 in the Y direction, inserts it under the pallet, and lifts it upward to remove the cover B held by the cover holding legs 10. Empty bobbin A
' and transport it to the designated shelf.

As described above, the present invention includes a shelf that supports and stores both ends of articles, a stacker crane that moves vertically and horizontally along the shelf to load and unload articles, and a loading/unloading system installed at the end of the shelf. In a three-dimensional storage shelf consisting of a storage station, cover holding legs are installed at the loading/unloading station, and when carrying in goods, the pallet on which the goods are placed is raised between the holding legs and from below the cover, and the cover is held by the goods. The cover is attached to the article by lifting it from the holding legs, and when carrying out, the pallet is lowered between the holding legs and from above the holding legs to hold the cover attached to the article on the holding legs and then removed. This brings about the following effects.

(b) The cover can be attached and detached simply by raising and lowering the pallet on which the goods are placed at the loading/unloading station to the storage shelf, without having to bring the cover into the production process or packaging process. There is no need for workers to attach or remove covers, and there is no need to damage stored items due to mistakes in attaching or removing covers.
It can be effectively carried out by an automated process.

(b) Storage efficiency can be increased because dirt prevention partition plates are not attached to the shelves.
