The present invention relates to a knob device of the controller, and more particularly to a knob device of the controller that can be improved by the shaking of the knob when the knob device is operated.

In general, various machines are equipped with a controller for automatically controlling the operation of the machine to meet the user's desired purpose or purpose.

The above-described controller is provided with an operating portion to which various commands are inputted by the user, and a display portion for displaying the operating state of the machine to the outside is formed. Therefore, the user can directly adjust the operation of the machine through the operation unit or change / set the program of the controller that controls the operation of the machine as appropriate.

In such an operation unit, various switches are installed to be operable so that various commands can be input by a user. The switches include a push switch, a slide switch, a rotary switch, and the like according to an operation method.

Here, a knob device is typical of the rotary switch, and the knob device is connected to a knob knob having a cylindrical shape rotatably disposed at the operation unit, and is connected to a rotational center of the knob to be in accordance with a rotation angle of the knob. It is configured to include an encoder (Encoder) for generating another control signal.

The knob is disposed to protrude from the control panel forming the exterior of the controller, the encoder is mounted on a substrate installed inside the controller and one end is connected to the back of the knob.

On the other hand, since the separation space is formed with a predetermined size between the control panel and the substrate, one end of the encoder is protruded long toward the knob side, the boss is inserted into the center of the back of the knob so that one end of the encoder can be connected to the encoder side It protrudes long.

In the knob device of the controller configured as described above, the boss of the knob is rotatably disposed inside the support boss, so that the boss of the knob and the support boss are in surface contact, so that friction noise is generated when the knob is rotated or frictional resistance. As a result, the operation feeling is greatly reduced, and the knob is shaken due to the gap between the boss and the support boss.

That is, when the gap between the boss of the knob and the support boss is largely formed, noise and operation feeling decrease due to friction during rotation of the knob are reduced, but there is a problem that the knob is greatly shaken in the vertical direction.

On the other hand, if the gap between the boss of the knob and the support boss is formed small, the phenomenon that the knob shakes up and down, left and right direction is reduced, but the friction is generated during the rotation of the knob to greatly reduce the friction noise and operation feeling There is a problem that the workability is also increased during assembly of the boss of the knob and the support boss.

Since the knob 30 is stably supported by the plurality of elastic bodies 100 as described above, even if the gap between the first boss 86 and the second boss 34 is wide, the top and bottom of the knob 30, Shaking from side to side is prevented.

Therefore, when the gap between the first boss 86 and the second boss 34 is wide, the second boss 34 is formed in the hollow portion of the first boss 86 when the knob 30 is assembled. Is easily inserted, and the frictional contact between the first boss 86 and the second boss 34 is reduced, so that the operation feeling of the knob 30 is improved.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, Of course it is possible.

The knob device of the controller according to the present invention configured as described above is equipped with an elastic support means having an elastic body rotatably elastically supporting the knob on the front of the knob supporter, the knob is stably installed by the elastic body The knob is prevented from shaking or tilting.

In addition, since the elastic support means is formed of a material having excellent wear resistance and lubricity, the knob is smoothly slid and rotated by the elastic support means during operation of the knob device to improve the operation feeling, and the durability of the knob device can be increased for a long time. There is an advantage.

In addition, the elastic body is composed of a connecting portion elastically deformable connected to one side of the elastic support means, an extended portion extending inclined forward from the connecting portion, and a protrusion projecting on the front end of the extension portion is seated the knob Therefore, only the knob and the protrusion are in contact with each other, so that the contact area of the knob is reduced, and noise generation and deterioration of operation feeling due to friction during operation of the knob device are prevented in advance.

In addition, since the knob is stably installed in the knob supporter due to the elastic body even when the distance between the first and second bosses is large, the design and manufacture of the knob device do not need to be precisely designed and manufactured. This has the advantage of being easily implemented.

In addition, the elastic support means having the elastic body is mounted on the front of the knob supporter, the knob device has the advantage that the knob is elastically supported simply by a simple structural change to add the elastic support means.
