Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a shelf facility in which a return shelf of the above-mentioned mounting tool is provided below a mounting shelf of the mounting tool for articles.

[Conventional technology]

In such a shelf facility, an operator located on the front side of the shelf takes out an article in a procedure of taking out an article placed on a placing tool located on the placing shelf section, and taking out the article. The mounting tool which has been completed will be supplied to the return shelf by the worker.

By the way, in such a shelf facility, it is installed and used with a working space provided on the front side thereof. By the way, the working space is used as a passage for the worker or as a space for handling the mounting tool when the mounting tool is taken out from the mounting shelf section and supplied to the return rack section.

[Problems to be solved by the invention]

In such a shelf facility, the vertical distance between the loading shelf and the returning shelf should be as narrow as possible so that the height can be lowered even when a large number of loading shelves are provided in the vertical direction. In addition, when installing such shelf equipment, it is desired to reduce the installation space by minimizing the width of the working space on the front side thereof.

However, if both of the above requirements are satisfied, there is a disadvantage in that the work of supplying the mounting tool to the return shelf is difficult to perform.

In other words, if the width of the work space is made sufficiently larger than the width of the mounting tool along the front-back direction of the shelf, the entire mounting tool is taken out horizontally into the working space and placed on the return shelf. It will be possible to supply smoothly. Also, if the vertical distance between the placing shelf and the returning shelf is sufficiently large, the placing tool taken out into the working space can be sent to the returning shelf in an inclined posture even if it cannot be placed in a horizontal posture. However, it is possible to supply smoothly.

Therefore, conventionally, the width of the working space is made sufficiently large, or the vertical interval between the placing shelf and the returning shelf is made sufficiently large to supply the placing tool to the returning shelf. Therefore, it is impossible to satisfy both of the above requirements, and improvement has been desired.

The present invention has been made in view of the above circumstances, and an object thereof is to satisfy both of the above requirements by a simple modification.

[Means for solving problems]

In the shelf equipment according to the present invention, a return shelf of the above-mentioned placing tool is provided below the placing shelf of the article placing tool, and the front end side portion of the above-mentioned placing shelf is: It is characterized in that it is provided on the back of the shelf so that it can be retired.

Then, in order to configure the front end side portion of the above-mentioned placing shelf part to be retractable toward the back side of the shelf, the front end side part is formed by a pair of arm-like bodies, and each of the arm-like bodies is formed into a base end. It is preferable to pivotally support the reciprocating swing around the vertical axis of the side.

In this case, the pair of arm-shaped bodies may be elastically biased toward the retracted side so that the arm-shaped bodies are automatically retracted and oscillated as the article mounting tool is removed upward.

Furthermore, when elastically biasing the pair of arm-shaped bodies toward the retreat side, it is possible to prevent the arm-shaped bodies from unnecessarily swinging toward the retreat side as the articles on the mounting tool are removed and the remaining amount thereof is reduced. Therefore, it is preferable to provide each of the pair of arm-shaped bodies with a frictional resistor that comes into contact with the lower surface of the mounting tool mounted on the arm-shaped body to prevent the arm-shaped body from retreating and swinging.

[Action]

 The operation of the above characteristic configuration is as follows.

That is, by retracting the front end side portion of the mounting shelf portion, the upper part of the front end side portion of the return shelf portion is opened,
It's the same as creating a large working space.

In other words, when supplying the mounting tool to the return shelf, by returning the front end side portion of the mounting shelf in advance, the mounting tool can be returned while also utilizing the space that expands accordingly. Can be smoothly supplied to the shelves.

When the front end side portion of the mounting shelf is formed of an arm-shaped body that is pivotally supported around the longitudinal axis on the base end side so as to be capable of retracting and swinging, the retracting swing of the arm-like body is It corresponds to the retreat of the front end side portion of the mounting shelf portion on the back side of the shelf.

As described above, when using a pair of arm-shaped bodies,
If each of the arm-shaped bodies is elastically biased toward the retracted side, the arm-shaped body automatically swings toward the retracted side when the placing tool is removed upward, and the arm-shaped body is retracted. The operation of swinging to the side becomes unnecessary.

Further, when elastically urging the arm-shaped body toward the retracted side, a frictional resistance body that comes into contact with the lower surface of the mounting tool to prevent the reciprocating swing of the arm-shaped body is provided in each arm-shaped body. , Even if the articles on the mounting tool are removed and the remaining amount is low,
Make sure to prevent the arm-shaped body from swinging toward the retreat side,
When the mounting tool is removed to the upper side, the arm-shaped body can be swung to the retracted side as appropriate.

[Effect of device]

 The effects of the present invention are as follows.

According to claim 1, when the mounting tool is supplied to the returning shelf, the front end side portion of the mounting shelf is retracted in advance, so that the mounting tool can be returned even in a space that expands. Since it can be used as a space for supplying to the shelves, the vertical spacing between the loading shelves and the returning shelves can be narrowed, and even if the width of the working space on the front side of the shelving equipment is reduced, Since the mounting tool can be smoothly supplied to the returning shelf, it is extremely useful for downsizing the shelf equipment itself and reducing the mounting space of the shelf equipment.

According to the second aspect, the front end side portion of the loading shelf can be configured to be retractable toward the back of the shelf with a simple structure. That is, the front end side portion can be slid back to the inner side of the shelf, but a simple structure for pivotally supporting the arm-shaped body is sufficient.

According to the third aspect, since the arm-shaped body can be automatically retracted and swung by removing the mounting tool upward, the operation of swinging the arm-shaped body to the retracted side is unnecessary, and the mounting operation is not required. The work of supplying the storage unit to the return shelf can be performed efficiently.

According to the fourth aspect, it is possible to reliably prevent the arm-shaped body from retracting and swinging unnecessarily before the mounting tool is removed to the upper side. It works well from the first article to the last article.
