- the operating device described in Patent Document 1 Japanese Unexamined Patent Application Publication No. 2003-22753 is configured such that a switch is turned on, off, A switch operating device that switches between “Ground” and a cam plate provided on the output shaft, and formed on the periphery of the cam plate at the positions corresponding to the “ON”, “OFF”, and “GROUND” positions of the switch.
- a cam provided with a pin formed in the surface of the cam plate, the pin contacting a switch for stopping the motor, and a cam rolling roller and a locking roller urged by the peripheral edge of the cam plate to roll.
- the cam that moves up and down by the rotation of the plate, the driven lever, and the cam rolling roller are in the “on”, “off”, or “ground” position of the cam plate, and the locking roller is locked in the concave portion and the output shaft rotates.
- Holding latch to lock the cam plate recess and cam rolling Micro switch that detects the engagement of the lock roller, and a lock release member that rotates by the horizontal movement of the lock lever, removes the lock roller from the concave portion of the holding latch and releases the lock, and a magnet.
- a lock release rod is provided.
- the switch operating device described in Patent Document 1 has the following problems.
- the stop position during electric operation varies: Limit before the stop target position
- the switch is operated and the electric brake is applied to the motor, but the braking characteristics are dependent on the load and operating voltage, and the stop positions vary widely.
- Control system is complicated: There are four limit switches for detecting the stop position, and many auxiliary relays are required. Disclosure of the invention
- the present invention provides a switch operating device that improves the stop position accuracy in electric operation, improves the stop position accuracy in manual operation (allowable range of pulling out the handle), and reduces the number of auxiliary relays to simplify the control system. To provide.
- the present invention has a structure in which the groove drives the roller and rotates the output shaft by the rotation of the groove cam shaft.
- FIG. 1 is a perspective view of an operation mechanism showing one embodiment of the present invention.
- FIG. 2 is an example of the groove locus of the groove cam shaft according to the present invention.
- FIG. 3 is a graphical representation of the groove locus of FIG.
- FIG. 4 is a graph showing a torque conversion rate when the groove locus of FIG. 2 is used.
- FIG. 1 is a perspective view of an operation mechanism showing one embodiment of the present invention.
- the rotational force of a motor 1 is transmitted by a spur gear 3 of a motor shaft 2 and a spur gear 4 meshing therewith to rotate a groove cam shaft 5.
- the groove cam shaft 5 can also be rotated.
- a groove 7 is formed in the manual handle 6, and a handle attaching / detaching restriction plate 8 can enter and exit the groove 7.
- the handle attaching / detaching restricting plate 8 is urged away from the groove 7 by the spring 9, and the manual handle 6 does not come off because the handle attaching / detaching restricting plate 8 enters the groove 7.
- a groove 10 is formed continuously in the axial direction.
- a roller 13 attached to the lever 12 of the output shaft 11 of the switch is arranged in the groove 10, and the roller 13 is guided by the groove 10 by the rotation of the groove cam shaft 5, and the lever ⁇ 1 2 Rotates right and left.
- a cam plate 14 is provided at an end of the grooved camshaft 5, and a collision roller 17 of a cam driven lever 16 enters and leaves a concave portion 15 formed in the cam plate 14.
- the cam follower lever 16 is pushed by the release coil 19, the impact roller 17 is recessed.
- the groove cam shaft 5 can be rotated from 15.
- the limit switch 20 detects this condition and turns the motor circuit ON.
- Fig. 1 shows the state of the intermediate position (the off position in the case of a single grounding).
- the collision roller 17 falls into the concave portion 15 of the cam plate, and the rotation of the groove cam shaft 5 is blocked.
- the release coil 19 is excited by a control device (not shown) and pushed by the release coil 19, so that the cam driven lever 16 is piled on the reset spring 18 and rotated clockwise.
- the collision roller 17 comes out of the concave portion 15 of the cam plate 14 and the groove cam shaft 5 can be rotated.
- the limit switch 20 detects this condition and turns on the motor circuit.
- the rotation of the motor 1 is transmitted to the groove cam shaft 5 by the spur gear 3 and the spur gear 4, and the groove cam shaft 5 rotates counterclockwise.
- the roller 13 engaged with the groove 10 of the groove cam shaft 5 is driven leftward, and the output shaft 11 is rotated counterclockwise (inward) by the lever 12.
- the collision roller 17 rides on the circular arc surface edge of the cam plate 14 and the rotatable state of the groove cam shaft 5 continues.
- the limit switch 20 detects this condition and releases the excitation of the release coil 19.
- FIG. 2 is an example of a groove locus of the groove cam shaft 5 according to the present invention
- FIG. 3 is a graph showing the locus
- FIG. 4 is a graph showing the torque conversion rate. Since the axial displacement is constant near the three stop positions, the stop position of the output shaft 11 does not change regardless of where the collision roller 17 stops in the concave portion 15 of the cam plate 14.
- the rate of change of the axial displacement with respect to the angle of the groove 10 is set to be small on the on and on the ground side, and large on the off side, so the torque conversion rate (output shaft torque / motor shaft torque) is
- the characteristics are close to the load torque of the switch body, and the load torque of the motor 1 can be made substantially constant.
- the grooved camshaft 5 rotates counterclockwise.
- the roller 13 engaged with the groove 10 of the groove cam shaft 5 is driven to the left, and the output shaft 11 is rotated counterclockwise (inward) by the lever 12.
- the collision roller 17 rides on the arcuate surface edge of the cam plate 14 and the rotatable state of the groove camshaft 5 continues.
- the limit switch 20 detects this condition and releases the excitation of the release coil 19. In this state (intermediate position), the handle attaching / detaching restricting plate 8 is engaged with the groove 7 of the manual handle 6, and the manual handle 6 does not come off.
- the collision roller 17 falls into the concave portion 15 of the cam plate 14 and the cam follower lever 16 rotates counterclockwise. With further rotation, the collision roller 17 collides with the wall surface of the concave portion 15 of the cam plate 14 and stops completely.
- the handle attachment / detachment restriction plate 8 is reset by the spring 9, and the manual handle 6 can be attached / detached.
- the switch operating device of the present invention has the following effects.
- the torque conversion rate (output shaft torque / motor shaft torque) H) has characteristics close to the load torque on the switch body side, so that the load torque of the motor can be kept almost constant and the load torque on the motor can be reduced.
