(57) [Summary] [Purpose] To eliminate vibration at the operation start position in a switching device that moves a cam switch having multiple contacts. [Structure] A disc 103, which is connected to a cam switch 101 and has a plurality of grooves 103a arranged on its circumference, is provided.
A lever 106 to which a pin 107 that can be engaged with is slidably connected is connected to the rotary solenoid 104, and a spring 109 that returns the pin 107 to the start position is provided.
10 and 111 are provided to eliminate the vibration of the pin 107 at the start position.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cam switch switching device.

[0002]

[Prior art]

 In the conventional cam switch switching device, as shown in FIG. 5, a disc 503 having holes 503a arranged at equal intervals on the circumference is attached to an operation shaft 502 of a cam switch 501, and a rotary solenoid is provided on an extension line of the operation shaft 502. 504 is provided, a lever 506 is attached to the output shaft 505 of the rotary solenoid 504, a pin 507 engageable with a hole 503a on the circumference of the disc 503 is slidably provided on the lever 506, and a linear solenoid 508 is provided. A pin 507 is connected and a bar 509 for returning the lever 506 to the start position is provided.

[0003]

[Problems to be solved by the device]

 In the prior art as shown in FIG. 5, since the lever 506 is used to bring the lever 506 to the start position, the lever 506 vibrates near the start position. For this reason, not only is it difficult to stop the lever 506 at the start position, but it is also impossible to execute the next switch switching operation while vibrating. The present invention solves the above problems and aims to prevent the lever from vibrating at the start position.

[0004]

[Means for Solving the Problems]

 The present invention provides a plurality of latches on both sides of the start position of the pin on the trajectory of the movement of the pin returning to the start position.

[0005]

[Action]

 According to the above construction, when the pin returns to the start position, it passes over the latch and is locked by the latch after passing the start position, so that the pin stays at the start position and does not vibrate.

【Example】

 1 is an external view of an embodiment of the present invention, FIG. 2 is a side view, FIG. 3 is a sectional view taken along line AA, and FIG. As shown in FIG. 1, FIG. 2 and FIG. 3, the disc 103 having grooves 103a at equal intervals on the circumference is attached to the operating shaft 102 of the cam switch 101, and the rotary solenoid 104 is provided on the extension line of the operating shaft 102. A lever 106 is attached to the output shaft 105 of the rotary solenoid 104, a pin 107 capable of engaging with the groove 103a is slidably provided in the lever 106, a linear solenoid 108 is connected to the pin 107, and the lever 106 is moved to a start position. A spring 109 for returning the pin is provided, and latches 110 and 111 are provided on both left and right sides of the start position of the pin 107. As shown in FIG. 4, when the linear solenoid 108 is excited in the switch changing operation, the pin 107 moves in the direction of arrow A and is inserted into the groove 103a of the disc 103. Subsequently, when the rotary solenoid 104 is excited, the lever 106 fixed to the output shaft 105 rotates in the direction of arrow B, and the disk 103 connected by the pin 107 is rotated by the operation angle of the cam switch 101. At this time, the pin 107 is not engaged with the latches 110 and 111. One cam switch switching operation moves the groove next to the groove 103a of the disk 103 to the initial position of the operation. After the cam switch switching operation, when the linear solenoid 108 is de-energized, the pin 107 is moved in the direction of arrow C by a return spring (not shown) and comes out of the groove 103a. Next, when the rotary solenoid 103 is de-excited, the spring 109 moves the pin 107 in the direction of arrow D, overcoming the latch 110 and returning to the start position. At this time, the pin 107 is locked by the latches 110 and 111 and does not vibrate.

[0007]

[Effect of device]

 As described above, according to the present invention, there are the following excellent effects. (1) The device can be easily stopped at the operation start position. (2) Since there is no vibration, the next switch switching operation can be performed immediately.
