Description

[Detailed Description of the Invention] The present invention relates to an operation box that is installed so as not to interfere with work and can be raised and lowered.

Conventionally, as shown in Figures 1 and 2, the operation box 4 needs to be installed at a location on the machine 1 that is within reach of the operator and close to the operator in order to proceed with the work efficiently. This can hit the head or body and interfere with work, and the effect is significant on multi-station machines with each station having an operation box or large machines that require a large number of operation boxes, and this has the disadvantage of impeding work efficiency. be.

In view of the above-mentioned drawbacks, the purpose of the present invention is to provide a liftable and lowerable control box that has a simple structure, is installed so that it does not hit the head or body, and can be stopped steplessly at any desired height, improving work efficiency. The purpose is to propose an operation box.

The present invention is characterized by comprising an operation box for controlling a device or a machine, and an elevating device connected to the operation box, which is in balance with the operation box and has a full range of motion for raising and lowering the machine up and down. Balance the weight of the operation box,
The operation box can be stopped steplessly at any height.

The present invention will be explained below with reference to illustrated embodiments. As shown in FIG. 3, the operation box that can be raised and lowered has one side of an arm 3 attached to the upper end of a support 2 set up on the floor or the machine 1, and a lifting device 5 for the operation box 4 is installed inside the arm 3. The upper end of the guide bar 6 is fixed to the other side, and the roller 7 is attached to the shaft 8 within the arm 3.
A wire rope 9 is rotatably supported on the roller 7, and an operation box 4 is suspended from one end of the wire rope 9. A handle 10 for pulling down the operation box 4 is attached to the lower end of the operation box 4, and a handle 10 for pulling down the operation box 4 is attached to the lower end of the operation box 4. The lower end of the movable part 11 is fixed.

The operation box 4 is provided with a plurality of operation buttons 4a and switches, and is connected to an electric cord extending from an electrical wiring duct 12, so that when the operation box is raised, it stops at a position higher than the height of the worker. It is set up so that it can be done.

The lifting device 5 is composed of, for example, a pulley around which the other end of the wire rope 9 is wound and a Zenmai. The force is set to balance the weight of the operation box 4.

The guide bar 6 prevents the operation box 4 from rotating or tilting, and is provided with an appropriate frictional resistance between the guide bar 6 and the movable part 11 so that the operation box 4 can stably stop at any position in the upper and lower operation range. There is. A plurality of guide bars 6 may be provided.

As described above, the operation box is configured to be able to be raised and lowered freely, and when the operator grasps the handle 10 and pulls it down, the wire rope 9 is let out against the full movement of the lifting device 5, and the operation box 4 is lowered and moved freely. It is stably stopped at the position , the operation button 4a is operated, and it can be lowered to any desired height, improving work efficiency.

Furthermore, when the operation is completed, simply pushing up the operation box 4 allows it to rise and move overhead. If the operation box 4 is moved overhead, it will not hit the operator's head or body, will not interfere with the movement of the operator, and the space below the suspended operation box can be used effectively.

In the above description, it was described that the lifting device 5 urges the pulley on the inside of the arm 3, around which the wire rope 9 is wound, in the winding direction with a full swing, but even if the pulley with a full swing is brought to the position of the roller 7, good. Furthermore, the lifting device may be provided at other positions such as inside and outside of the support column 2.

The handle 10 may be attached to the side of the operation box 4.

The arm 3 may be attached to the column 2 so as to be rotatable laterally.

Since the present invention is configured as described above, if the lifting stop position of the operation box is set at a position higher than the height of the worker, it will not interfere with the movement of the worker, and the operation box can be adjusted freely according to the height of the worker. Since it can be operated by lowering it to a height of 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,00,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,The It is possible to provide an operation box that can be raised and lowered freely.

Further, since the lifting device has a full swing and the hoisting force of the full swing is balanced with the weight of the operation box, the structure is simple and can be made small.
