Description

[Technical Field] The present invention relates to a storage device that lowers and takes out a storage body having a front opening with respect to an outer shell case having a lower opening, and stores the storage body by driving it upward. The present invention relates to a technique for solving a problem when driving and raising a storage body.

[Background Art] Conventionally, in a storage device in which a housing body having an opening at the front side is lowered to be taken out with respect to an outer shell case having an opening at the lower side and stored by being driven to rise, in order to drive and raise the storage body, If the article stored in the opening of the storage body is protruding from the front edge of the storage body, or if your fingers are placed on the lower edge of the storage body, the article may be packed and deformed as the storage body rises. However, there is a problem in that it may be damaged, or the fingers may be injured.

[Object of the Invention] The present invention has been made in view of the above problems,
It is an object of the invention to provide a storage device that does not accidentally pack articles or fingers when the storage body is raised.

DISCLOSURE OF THE INVENTION In the storage device of the present invention, a housing 2 having an opening at the front is driven downward to be taken out from an outer shell case 1 having an opening at the bottom,
A storage device that is driven to move up to be stored, and is a storage body 2.
Is in the raised storage position, the article detection switch 3 is arranged below the outer shell case 1 and in front of the lower edge of the opening of the storage case 2, and the storage case is detected based on the detection result of the articles by the article detection switch 3. It is characterized in that it is configured to stop the raising and lowering drive of No. 2, and the above-mentioned object is achieved by such a configuration. That is,
In a state where the storage body 2 is in the raised storage position, the article detection switch 3 is arranged below the outer shell case 1 and in front of the lower edge of the opening of the storage body 2, and based on the detection result of the articles by the article detection switch 3. By configuring so as to stop the raising and lowering drive of the storage body 2, the storage body 2 is driven and lifted when the article stored in the storage body 2 is protruding or when the article is put on a hand. Then, the protruding article and the hand are detected by the article detection switch 3, and based on the detection result, the ascending drive of the container 2 is stopped, and the article is deformed, broken, or further injured. It was made so that nothing happened.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In the storage device A, a top plate is attached to the upper end of a rectangular tube-shaped outer shell case 1, the lower end is opened, and a door 4 having a double door structure is attached to the front opening. With respect to the outer shell case 1 having such a rectangular tube shape, the storage body 2 opened forward can be driven down to be taken out, and driven up to be stored. The raising and lowering drive of the storage body 2 is performed by the storage device A.
A motor such as a hydraulic motor is driven by a closing operation of an operation switch (not shown) provided below the
Thus, the hydraulic cylinder is expanded by the hydraulic oil sent under pressure to lower the container 2, and the container 2 is retracted by retracting the hydraulic cylinder. In this way, the drive configuration for driving and raising the storage body 2 includes a screw shaft that is rotationally driven by a motor, a moving body that is screwed into the screw shaft so that the storage body 2 can be fixed to the storage body 2, and the like. It is possible to change the design in various ways such as a mechanical configuration.

The article detection switch 3 is disposed below the outer shell case 1 and in front of the lower edge of the opening of the container 2 when the container 2 is in the raised storage position. The article detection switch 3 includes, for example, a safety bar 5 that is vertically swingably held within a certain small range at the tip of a swing arm 9 that is swingably held, and the safety bar 5 is lifted above a certain level. The safety bar 5 is pushed up to operate the limit switch 6 so that the power supply circuit of the motor is cut off and the raising of the housing 2 is stopped. Limit switch 6 is curtain plate 7
Is attached to the back of the device via a mounting member 8.

In this way, the storage body 2 in the raised storage position of the storage body 2
The safety bar 5 is provided so as to face the vicinity of the lower edge of the opening, and the safety bar 5 is pushed up by pushing up the safety bar 5 when an article stored in the storage body 2 is protruding or when a hand is put on the article. Operate the limit switch 6 to store
That is, the ascending drive is stopped and the article is not deformed, broken, or further injured.

The article detection switch 3 can be designed in various ways, such as by using a piezoelectric tape switch that conducts electricity when a phototube or an article hits it. Further, the storage device A can be used for opening and closing the top and bottom of a storage wall, a system kitchen, a compolyer, etc.

[Advantages of the Invention] The present invention required as described above has the article detection switch disposed below the outer shell case and in front of the lower edge of the opening of the storage body when the storage body is in the raised storage position. Since it is configured to stop the raising / lowering drive of the storage body based on the detection result of the storage container, the storage body is opened when the articles stored in the storage body are protruding or when the hand is put on the articles. When the drive is raised, the protruding article and hand are detected by the article detection switch, and based on this detection result, the raising drive of the container is stopped, and the article is deformed, broken, or further injured. There is an advantage that there is no such thing. Further, since the article inspection switch is arranged below the outer shell case and in front of the lower edge of the opening of the container when the container is in the raised storage position, it is possible to visually confirm the protruding item or the hand. When it is recognized in advance that it will be sandwiched between the storage case and the outer shell case, it is possible to easily operate the article inspection switch from the outside even if the storage body is about to fit in the outer shell case. It is possible to stop the upward drive of the container by operating the article inspection switch, and the article inspection switch can be used as an emergency stop switch.
