Description

[Detailed description of the invention] The present invention is provided with a large number of article supports in the direction of rotation and in a direction perpendicular to the rotation direction, and in an article loading/unloading work area, article supports are arranged in parallel in the direction perpendicular to the rotation direction. The present invention relates to a rotating shelf device that is provided with a plurality of opening/closing doors arranged in parallel corresponding to sections, and is intended to allow articles to be loaded and unloaded without error and efficiently.

Hereinafter, one embodiment of the present invention will be described based on the attached illustrative drawings. Reference numeral 1 denotes a rotary shelf body, and a left and right pair of gear wheels 2a and 2b are suspended between an upper and lower pair of gear wheels 2a and 2b and rotate in conjunction with each other. A large number of shelves 4 are hung at regular intervals between the endless chains 3a and 3b, and each shelf 4 has two upper and lower shelf boards 4a, and a large number of articles can be stored on each shelf board 4a. A basket 5 is supported so that it can be taken in and out. 6 is basket 2
This is a partition wall with shelves arranged in rows. 7 is a drive motor for rotating the endless chains 3a, 3b.

Reference numeral 10 denotes an opening for taking in and taking out articles, and a shelf 4 is provided at a position directly above the workbench of the front wall portion 9 provided with the workbench 8.
It is located across the entire width of the area. 11 is an opening/closing door that opens and closes the opening 10, and in the length direction of the opening 10, that is, the length direction of the shelf 4 (the rotating shelf width direction perpendicular to the rotation direction of the shelf 4), It is divided into a plurality of parts so as to correspond to each one of the article storage baskets 5, and each can be opened and closed separately. In this embodiment, each opening/closing door 11 is of a shutter type that can be vertically raised and lowered, is biased in the closing direction by its own weight, and is provided with a handle 12 for opening. Reference numeral 13 denotes a magnetic locking means provided for each opening/closing door 11. Only when it is energized, the magnetic locking means 13 attracts the upper end attracted portion 14 of the opening/closing door 11 that has reached the opening movement limit position, and locks the opening/closing door. 11 is automatically locked at the opening limit position.

Reference numeral 15 denotes an indicator light as a display means for instructing which opening/closing door 11 to open, and is arranged in parallel for each opening/closing door 11. This indicator light 15 is automatically turned on in response to a signal from a microprocessor that controls the inventory management of the carousel 3 and automatic loading/unloading operation, and is connected to each of the magnetic locking means 13. are electrically connected so as to be excited when the indicator light 15 corresponding to the same opening/closing door is turned on.

In addition, as shown in FIG. 3, the article support part of each shelf 4,
That is, the basket support portion on the shelf board 4a is provided with a stopper 16 for preventing the basket 5 from slipping.
A stopper 17 is provided which engages with the upper side of the rear side plate of the basket 5 which is pulled out over the stopper 16.

Automatic loading and unloading of the carousel 3 is performed in a conventionally known manner. For example, by keying in the code number of an article to be delivered, a specific article support section (shelf board 4a
Each shelf 4 rotates and stops so that the upper unit compartment) reaches a position adjacent to the opening 10. The same applies to warehousing work. When the corresponding article support part stops at a position adjacent to the opening 10, the indicator light 15 is automatically turned on to indicate which opening/closing door 11 the article support part to be loaded/unloaded has reached. lights up. The operator confirms that the indicator light 15 is lit and lifts the door 11 in the lit position against gravity to open it. Since the magnetic locking means 13 is excited at the same time as the indicator light 15 lights up, when the opening/closing door 11 reaches the opening limit position, the attracted part 14 comes into contact with the locking means 13 and is attracted to the handle 12. Even if the hand is released, the opening/closing door 11 is locked without falling. If the other opening/closing door 11 is located in a position where the indicator light 15 is not lit, even if it is opened, the locking means 1 will not be activated.
Since the locking action by 3 is not performed, the opening/closing door 11
When you let go of it, it will close automatically due to gravity.

As described above, if only the opening/closing door 11 located adjacent to the article support section to be loaded/unloaded is opened and the opening/closing door 11 is locked at the opening limit position, the corresponding article can be accessed through the opened opening 10. The basket 5 on the support part is pulled out as shown by the imaginary line in FIG. 3, and articles can be taken in and taken out.

When the loading and unloading work is completed, the open door 11 must be closed. For example, by operating the work end button, the locking means 13 is demagnetized and the indicator light 15 is turned off. It can be configured so that it closes naturally.

In the embodiment, the opening/closing door 11 used is an elevating shutter type that closes due to gravity, but a door that rotates around a hinge in the horizontal or vertical direction, or a shutter type that slides horizontally and horizontally is also used. The opening/closing door may be any type of opening/closing door, such as a door, and a spring may be used as a means for biasing the door in the closing direction. Furthermore, the locking means for locking the opening/closing door 11 at the opening limit position may be of any configuration, such as a locking means equipped with a locking pawl that can be switched between a locking position and a retracted position using a solenoid. That's fine.

Although the rotary shelf main body 1 is exemplified as one that cyclically rotates up and down, it may also be one that cyclically rotates horizontally. In this case, each vertically elongated shelf 4 is provided with a plurality of article support sections in the vertical direction, and the parallel direction of the opening/closing doors 11 is the vertical direction.

The rotating shelf is exemplified as having a structure in which a plurality of article support parts arranged in parallel in the width direction perpendicular to the direction of rotation of the rotating shelf rotate together; The rotating shelf may have a structure in which a plurality of article support parts are divided into a plurality of parts so that each part can be rotated separately. Further, the opening 10 may be composed of a plurality of independent openings for each opening/closing door 11.

Although various implementation methods have been described, in short, the rotating shelving device of the present invention is provided with a large number of article supporting parts in the direction of rotation and in a direction perpendicular to the rotating direction, and a work area for loading and unloading articles is provided with a plurality of article supporting parts perpendicular to the rotating direction. The rotating shelf device is provided with a plurality of opening/closing doors arranged in parallel corresponding to the article support parts arranged in parallel in the direction in which the opening/closing door is opened; Each of the opening/closing doors is biased in the closing direction by gravity or a spring force, and a locking means is provided for locking the opening/closing door at the opening limit position only for the opening/closing door in the open position indicated by the display means. Therefore, the worker must carry out loading/unloading work at a location where two conditions are satisfied: the display on the display means and the opened/closed door being locked by the locking means. This ensures accurate stocking and unloading operations without errors. Moreover, since the opening/closing door is automatically locked at the opening limit position, it is possible to carry out the work of entering and exiting the warehouse easily and efficiently using both hands.
