Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an opening / closing device for a safety cabinet, which includes a front cover provided on the outer periphery of a processing device such as a sheet metal processing machine, and a rear cover that is provided in a pair with the front cover so as to be able to seal the inside of each other.

[0002]

[Prior Art]

 Conventionally, a safety cabinet is a box-shaped protective cover that covers the periphery of a processing apparatus such as a sheet metal processing machine, and is configured to seal the inside and open and close.

[0003]

[Problems to be solved by the device]

 By the way, when exhausting smoke from the inside of the cover, the front cover and the rear cover are moved to the left and right to be opened, which causes a problem that a space for opening the cover becomes large.

Further, also in the maintenance of the processing apparatus, there is a problem that a space becomes large due to the similar opening of the cover.

In order to solve the above problems, an object of the present invention is to provide a safety cabinet opening / closing device in which the cover can be opened / closed in a small space and the structure thereof is easy.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a safety cabinet comprising a front cover provided on the outer periphery of a processing device and a rear cover which is paired with the front cover and can seal the inside of each other. A movable member that is provided at the bottom of the front cover and the rear cover to allow the front cover and the rear cover to move, and a movable member that is provided on the floor to guide the movable member to retract the rear cover by a required amount in the horizontal direction. An opening / closing device for a safety cabinet, comprising: a movable member guide portion that is rotated in a horizontal direction to be brought into an overlappingly opened state with the rear cover.

[0007]

[Action]

 By adopting the opening / closing device of the safety cabinet according to the present invention, movable members having movable front and rear covers are provided at the bottom of the front and rear covers, and the movable member is provided on the floor to guide the movable rear cover. By providing a movable member guide part on the floor that retracts the front cover horizontally by the required amount and rotates the front cover horizontally to overlap the rear cover to open the structure, the structure is easy and the cover can be opened and closed. Is space-saving.

【Example】

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

FIG. 8 is a perspective view of a closed state of a safety cabinet in which the present invention is implemented, FIG. 9 is a front view of FIG. 8, FIG. 10 is a bottom view of FIG. 9, FIG. 11 is a left side surface of FIG. Shows the right side view of FIG. 8 to 12, the safety cabinet 1 is formed in a substantially hemispherical shape and is vertically divided into a front cover 1F and a rear cover 1R.

Further, a window portion 5 made of, for example, a transparent plastic material extending in the left-right direction is provided at a predetermined height position from the floor surface in the height direction of the cabinet 1, and the inside is monitored. Is possible. An operation panel 7 is attached to a part of the window 5 so that the processing device 3 provided inside the cabinet 1 can be operated from the outside.

A work carry-in port 9 is provided at the center of the lower portion of the front cover 1F, and a work carry-in port shutter 11 that is vertically openable and closable is provided at the work carry-in port 9. A product carry-out port 13 is provided at the center of the lower portion of the rear cover 1R, and a product carry-out port shutter 15 that can be opened and closed in the vertical direction is provided at the product carry-out port 13.

FIG. 1 is a perspective view of a safety cabinet in an open state in which the present invention is implemented, FIG. 2 is a front view of a rear cover in a rearward moving state, FIG. 3 is a bottom view of FIG. 2, and FIG. A front view of the state, and FIG. 5 shows a bottom view of FIG. 1 to 5, the cabinet opening / closing device 6 includes a movable member provided on the bottom surface of the covers 1F and 1R, a plurality of bearings 17 in this embodiment, a movable member guide portion, and a floor portion 19 in this embodiment. It is composed of a groove portion 21 provided. The plurality of bearings 17 are provided on the bottom surface of each of the front cover 1F and the rear cover 1R.

Further, as shown in FIG. 6, a groove portion 21 having a sufficient depth for accommodating the bearing 17 is provided in the floor portion 19, and a bearing provided at the bottom of the groove portion 21 on the bottom surface of the covers 1F, 1R. 17 comes into contact with the cover 1F. 1R can be moved horizontally. This cover 1F. When opening and closing the 1R, the bearing 17 is rotatable along the groove 21. Therefore, as shown in FIG. 7, the groove portion 21 is a guide for opening and closing the covers 1F and 1R, and is a circular groove 23 formed in the floor portion 19 in a 360-degree circumferential direction, and the circular groove 23. The straight groove 25 has a required length L and is in contact with one end.

With such a configuration, the front cover 1F and the rear cover 1R are always held in the closed state by incorporating the processing device 3 therein. When loading a work, the work loading port shutter of the front cover 1F opens upward, and the work is loaded from the work loading port. When the work is carried in, the work carry-in shutter is lowered downward and closed.

The safety cabinet 1 is opened when the internal temperature of the safety cabinet 1 rises, smoke needs to be exhausted, or at the time of maintenance during processing of a workpiece. Therefore, the rear cover 1R horizontally moves rearward along the straight groove 25 of the groove 21 as shown in FIG. 6 (left side in the drawing).

Next, the front cover 1F is rotationally moved in the horizontal direction by 180 degrees along the circular groove 23 of the groove portion 21 to open the safety caninet 1. The position of the front cover 1F at this time is the same as the position of the rear cover 1R when the safety cabinet 1 is closed. The amount of movement of the rear cover 1R to the rear is the length L of the linear groove 25 such that the inside of the rear cover 1R and the outside of the front cover 1F do not interfere with each other when the safety cabinet 1 is open.

Therefore, the cabinet opening / closing device 6 opens the rear cover 1R so that the rear cover 1R is horizontally moved rearward and the front cover 1F is horizontally rotated to be overlapped with the rear cover 1R. The cabinet 1 can be opened and closed, the opening and closing operations of the covers 1F and 1R are saved, and the noise is considerably reduced while the work is being processed, but the operator operates the operation panel 7 from the outside to operate the window. It is safe to monitor from.

It should be noted that the present invention is not limited to the above embodiment, but can be implemented in other aspects by making appropriate design changes, for example, instead of the groove portion 21, a floor surface. A reel may be laid on the bottom of the cover and a car that can rotate in the horizontal direction may be provided on the bottom surface of the cover. It is also possible to use a guide bar and a guide block. Further, it is easy to provide a temperature sensor or a smoke sensor inside the safety cabinet 1 to automatically operate the cabinet opening / closing device when the temperature rises or smoke is generated.

[0019]

[Effect of the device]

 As is apparent from the above description, the opening / closing device of the safety cabinet of the present invention is provided with a movable member at which the front cover and the rear cover are movable, at the bottom of the front cover and the rear cover, and at the floor. By providing the movable member guide portion on the floor portion which guides the rear cover horizontally backwards by a required amount and rotates the front cover horizontally so as to be overlapped with the rear cover and opened. The points are effectively solved, the configuration is easy, and the opening and closing of the cover saves space and labor.
