Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a plurality of rotating storage containers rotatably like a ferris wheel in a storage box so that the storage items can be stored in each rotation storage container. The present invention relates to the structure of a safety device that prevents the rotary storage container from being inadvertently driven when the stored items are taken in and out.

[Prior Art] In recent years, a plurality of rotary storage containers are rotatably provided like a ferris wheel in a storage box, and a rotary storage is provided on the front of the storage box with an opening for taking in and out corresponding to an appropriate rotary storage container. The body is being offered. Such a rotary storage body rotates the rotary storage container in the storage box, aligns an appropriate rotary storage container with an opening for loading and unloading, and stops, so that the rotary storage container can be loaded and unloaded. There is. By the way, in such a rotary storage container, it is dangerous if the rotary storage container is inadvertently driven while the storage container is being put in or taken out. There is also a limit switch that detects when the front cover hits when it rotates and stops driving.

[Problems to be solved by the invention] However, in such a conventional example, since the safety means such as the limit switch and the operation portion such as the operation switch for operating the drive of the rotary storage container are separately provided, There is a problem that it takes time to install and install, and there is a problem that the work such as wiring becomes complicated and a construction error easily occurs.

The present invention has been made in view of the above-described points, and the object of the present invention is to provide a safety device for a rotating storage body that can be easily installed and installed, is easy to perform wiring work, and has fewer installation errors. To provide.

[Means for Solving the Problems] In order to achieve the above object, in the safety device for a rotary storage container according to the present invention, the rotary storage container 2 is driven in a state where the front lid 4 of the rotary storage container 2 is open and protrudes into the opening. Limit switch 5 that detects and stops when it tries to, and the rotary storage container 2
An operation switch 6 for operating the driving of the switch mounting body 7 is integrally provided on the switch mounting body 7, and the switch mounting body 7 is attached to the upper edge of the opening 3 for taking in and out. The touch bar 15 is provided for activating the rotary storage container 2 to stop the drive of the rotary storage container 2.

[Operation] Due to the above-mentioned configuration, the limit switch 5
The limit switch 5 and the operation switch 6 can be installed simply by attaching the switch mounting body 7 in which the operation switch 6 and the operation switch 6 are integrally provided. Moreover, when the article is taken out and stored, the hand holds the upper edge of the opening and the rotary storage container. It is possible to avoid accidentally getting caught between and and to ensure safety.

[Embodiment] The storage box 1 is in the shape of a rectangular box that is long in the vertical direction, and has a back plate 1a and side plates 1.
b, the upper plate 1c, the lower plate 1d, the front plate 1e, etc.
A rotation drive device 8 is installed inside the back of the storage box 1. The rotary drive unit 8 has a plurality of (eight in this embodiment) arms 10 projected from a vertically long annular drive body (not shown) driven by a motor 9, and a mounting portion at the tip of the arm 10. 12 is projected from the back plate 13, and the mounting portion 12 is guided by the oblong guide groove 14 provided in the back plate 13. The rotary storage container 2 is formed, for example, as shown in FIG. 7, and has an openable and closable front lid 4 mounted on the front surface. A plurality (eight in this embodiment) of the rotary storage containers 2 are arranged in the storage box 1, and the rotary storage containers 2 are attached to the mounting portions 12, respectively. Then, when the motor 9 is driven, the rotary storage container 2 is rotationally driven like a ferris wheel through the annular drive body and the arm 10. On the front surface of the storage box 1, there is provided an opening 3 for taking in and out which has a size such that the rotary storage container 2 is exposed. As shown in FIGS. 4 and 5, the switch mounting body 7 is formed in a case shape that is long in the left and right, and the operation switch 6 is provided on the front surface of the switch mounting body 7. The operation switch 6 has a plurality of push buttons 6a, 6b, 6c ... For example, the push button 6a is for ON, 6b is for operating so that the first and second rotary storage containers 2 reach the position of the opening 3, and 6c is for opening the third and fourth rotary storage containers 2. 6d is for operating so that the fifth and sixth rotary storage containers 2 are up to the opening 3, and 6e is for operating
And 8th rotation storage container 2 is operated so as to reach the opening 3, 6f is operated so that the rotation storage container 2 is continuously rotated, and 6g is a stop operation. is there. Further, on the side of the front surface of the switch mounting body 7, a stored item display plate 11 for displaying the contents of the stored item is mounted. Switch mounts 18 are attached to the back of the switch mount 7 in the longitudinal direction, and limit switches 5 are attached to both ends of the switch mounts 18, respectively. A touch bar 15 is arranged below the switch mounting body 7.
5 is attached to the push button 5a of the limit switch 5. When the touch bar 15 is pressed, the limit switch 5 operates to stop the driving of the rotary storage container 2. The switch mounting body 7 is arranged at the upper edge of the opening / closing opening 3 and is mounted by an L-shaped mounting bracket 16 as shown in FIG. The rotary storage body is configured as described above, and the specified rotary storage container 2 is rotated by operating the operation switch 6 and is stopped at the opening / closing opening 3 for loading / unloading the stored items. . At this time, even if the rotary storage container 2 is inadvertently driven while the front lid 4 is opened and the storage contents are taken in and out, the storage switch and the front lid 4 hit the touch bar 15 and the limit switch 5 operates to rotate the rotary storage container 2. Rotation is stopped.
Further, it is possible to use the shelf furniture 17 adjacent to the shelf furniture 17 with the opening 3 for taking in and out exposed in the rotary storage body configured as described above.

[Effects of the Invention] As described above, the present invention provides a limit switch for detecting and stopping when the rotary storage container is driven when the front cover of the rotary storage container is open and protruding to the opening, and the rotary storage container Since the operation switch for operating the drive is provided integrally with the switch mounting body and this switch mounting body is attached to the upper edge of the opening for taking in and out, it is not mounted separately as in the past, but simultaneously installed. The limit switch and operation switch can be installed and installed easily, and wiring can be done in one place for easy wiring work.Because the limit switch and operation switch are integrated, The reliability of the switch system is improved without construction errors, and the limit switch is placed below the switch mounting body. There is a touch bar that activates the switch to stop the drive of the rotating storage container.Therefore, the rotating storage container can be unexpectedly used when you put your hands into the rotating storage container from the opening of the storage box to store and retrieve articles. When driven, the hand is caught between the front lid of the rotary storage container and the upper edge of the opening, and when the hand touches the touch bar, the limit switch is operated to stop the drive of the rotary storage container and for safety, the touch bar Is provided below the switch mounting body, and the touch bar can be provided at a proper position by effectively utilizing the configuration of the switch mounting body.
