Description
- The present invention relates to an operating mechanism for a switch, and more particularly to an operating mechanism for a switch designed to have both functions of a disconnecting switch and an earthing switch and to be switched between three positions "CLOSED", "OPEN" and "EARTHED" by a single operating unit.
- There has been known a three-position switch, such as a disconnecting switch with an earthing switch, which is designed to have both functions of a disconnecting switch and an earthing switch and to be switched between three positions "CLOSED", "OPEN" and " EARTHED " by a single operating unit. For example,
FR-A-1206991 2003-22735 - The operating mechanism disclosed in the Patent Publication 1 is designed to rotate an output shaft using either a motor or a manual handle so as to operate the three-position switch between "CLOSED", "OPEN and "EARTHED". More specifically, the operating mechanism comprises: a cam plate fixed to the output shaft and formed with three depressions at positions corresponding to the switch positions "CLOSED", " OPEN "and" EARTHED "; pins formed on a surface of the cam plate and adapted to be brought into contact with four limit switches for stopping the motor; a cam-follower lever which is provided with a locking roller and a on-cam rolling roller biasedly pressed onto and rolled along a circumferential edge of the cam plate, and adapted to be vertically moved according to a rotation of the cam plate; a retaining latch formed with a concave portion and adapted to allow the locking roller to be engaged with the concave portion when the on-cam rolling roller is located at each of the depressions of the cam plate corresponding to the switch positions "CLOSED", "OPEN" and " EARTHED ", so as to lock a rotation of the output shaft; limit switches for detecting the engagement between the on-cam rolling roller and each of the depressions of the cam plate; a lock release member adapted to be moved according to a horizontal movement of a lock lever so as to disengage the locking roller from the concave portion of the retaining latch to release the lock; and a lock release rod adapted to be driven by a magnet.
- The operating mechanism disclosed in the Patent Publication 1 has the following problems:
- (1) Wide variation in stop position of a switch during motor operation: While each of the limit switches is activated just before each target stop position to electrically brake a motor, the stop position is largely varied due to motor's braking characteristic depending on load torque and operating voltage;
- (2) Wide variation in stop position of the switch during manual operation: While the operating mechanism is designed to inhibit a manual handle from being pulled out except that the switch is in a given stop position, allowable range of handle pulling-out is relatively wide; and
- (3) Complexity in control system: The operating mechanism includes the four limit switches for detecting respective target stop positions, and thereby requires a number of auxiliary relays.
- The present invention is directed to provide a switch operating mechanism capable of achieving enhanced accuracy in a stop position of a switch during an electric motor-based operation and in a stop position of the switch (in detachable position of a manual handle) during a manual handle-based operation, while reducing the number of auxiliary relays to simplify a control system.
- The feature of the present invention is generally summarized as follows.
- (1) An operating mechanism of the present invention comprises a grooved cam shaft designed to be rotated so as to drive a roller to thereby rotate an output shaft.
- (2) The grooved cam shaft has a groove configured such that an axial displacement of the groove relative to a rotation of the grooved cam shaft is minimized around a position corresponding to a stop position of the switch to prevent the output shaft from being rotated even if the motor is rotated.
- (3) The grooved cam shaft may have a groove configured such that an axial displacement rate of the groove relative to a rotation of the grooved cam shaft is in approximately inverse proportional to a load torque of the switch so as to achieve constant load torque for the motor.
- (4) The grooved cam shaft may include a cam plate formed with a concave portion designed to allow a bump roller to fall therein and bump thereagainst so as to stop a rotation of the grooved cam shaft.
- (5) A state when the bump roller is in the falling position may be detected using a limit switch to stop the motor.
- (6) A manual handle may be inhibited from being pulled out except that the bump roller is in the falling position.

FIG 1 is a perspective view showing an operating mechanism according to one embodiment of the present invention. InFIG. 1 , the operating mechanism is designed to transmit a torque of a motor 1 to agrooved cam shaft 5 through a spur gear 3 of a motor shaft 2 and a spur gear 4 engaged with the spur gear 3. - In place of the motor 1, a manual handle 6 may be connected to the motor shaft 2 to rotate the spur gear 4 so as to rotate the
grooved cam shaft 5. The manual handle 6 is formed with agroove 7, and aninhibition plate 8 for inhibiting the manual handle 6 from being inserted and pulled out from the motor shaft 2 is disposed adjacent to thegroove 7 in an engageable manner relative to thegroove 7. Theinhibition plate 8 is biased in a direction away from thegroove 7 by a spring 9. When theinhibition plate 8 is engaged with thegroove 7, the manual handle 6 is inhibited from being pulled out of the motor shaft 2. Thegrooved cam shaft 5 has an outer peripheral surface formed with agroove 10 axially extending continuously like a spiral. Thegroove 10 receives therein aroller 13 which is attached to one end of alever 12 having the other end fixed to an output shaft 11 associated with a switch. When thegrooved cam shaft 5 is rotated, theroller 13 is swung rightward or leftward (inFIG 1 ) about thelever 12 while being guided along thegroove 10. - A
cam plate 14 is fixed to one end of thegrooved cam shaft 5. Thecam plate 14 is formed with aconcave portion 15 adapted to be engageable with abump roller 17 attached to a first end of a T-shaped cam-follower lever 16. The cam-follower lever 16 is biased by areset spring 18 attached to a second end thereof in such a manner as to allow thebump roller 17 to be engaged with theconcave portion 15. When a third end of the cam-follower lever 16 is pushed by arelease coil 19, the cam-follower lever 16 is swung to disengage thebump roller 17 from theconcave portion 15 so as to allow thegrooved cam shaft 5 to be rotated. Simultaneously, alimit switch 20 is activated by the pushed cam-follower lever 16 to detect this state and turn on a drive circuit of the motor 1. - In manual operation, when the cam-
follower lever 16 is pushed by therelease coil 19, theinhibition plate 8 is moved by the second end of the cam-follower lever 16 and engaged with thegroove 7 of the manual handle 6 to inhibit the manual handle 6 from being pulled out of the motor shaft 2. - An operation of the operating mechanism according to this embodiment will be described below.
- In
FIG 1 , the operating mechanism is in an intermediate position ("OPEN" position in the case of the switch has three positions "CLOSED", "OPEN" and "EARTHED"). In this position, thebump roller 17 falls in theconcave portion 15 of the cam plate to lock the rotation of thegrooved cam shaft 5. - When a control unit (not shown) receives a command for closing operation, the
release coil 19 is energized according to the control unit to push the cam-follower roller 16. Thus, the cam-follower roller 16 is swung clockwise against thereset spring 18, and thebump roller 17 is moved to disengage from theconcave portion 15 of thecam plate 14 so as to allow thegrooved cam plate 5 to be rotated. Simultaneously, thelimit switch 20 detects this state and turns on the drive circuit of the motor 1. - Thus, the motor 1 is rotated, and a torque of the motor 1 is transmitted to the
grooved cam shaft 5 through the spur gears 3, 4 to rotate thegrooved cam shaft 5 counterclockwise. Theroller 13 engaged with thegroove 10 of thegrooved cam shaft 5 is driven or swung leftward (inFIG 1 ), and the output shaft 11 is rotated through thelever 12 in a counterclockwise direction (direction to the "CLOSED" position). In the state after thegrooved cam shaft 5 is rotated at some degrees, thebump roller 17 is placed and rolled on a circular circumferential surface of thecam plate 14 to maintain the rotatable state of thegrooved cam shaft 5. Thelimit switch 20 detects this state to de-energize therelease coil 19. - Then, when the
grooved cam shaft 5 is rotated at about 360-degree, thebump roller 17 falls in theconcave portion 15 of thecam plate 14, and the cam-follower lever 16 is swung counterclockwise. Thelimit switch 20 detects this state to turn off the drive circuit of the motor 1. While the motor 1 inertially rotates for a while, it will be completely stopped when the bump roller 17 bumps against a wall surface of theconcave portion 15 of the cam plate. -
FIG 2 shows one example of the configuration of thegroove 10 of thegrooved cam shaft 5, andFIG 3 is a graph showing the groove configuration.FIG. 4 is a graph showing a torque conversion rate in the groove configuration. Thegroove 10 is configured to have no axial displacement around each of three positions corresponding to the three stop positions of the switch. Thus, even if thebump roller 17 is stopped at any position within theconcave portion 15 of thecam plate 14, a stop position of the output shaft 11 is not varied. - In
FIG 2 , an axial displacement rate relative to an angle of thegroove 10 is arranged to become smaller on the side of the "CLOSED" and "EARTHED" positions and become larger on the side of the "OPEN" position. Thus, as shown inFIG 4 , a torque conversion rate (output shaft torque/motor shaft torque) has a similar characteristic to that of a load torque in a body of the switch. This makes it possible to maintain a load torque of the electric motor 1 at an approximately constant value. - In
FIG 1 , thebump roller 17 falls in theconcave portion 15 of thecam plate 14 to lock the rotation of thegrooved cam shaft 5, and theinhibition plate 8 is returned to its initial position to allow the manual handle 6 to be inserted and pulled out from the motor shaft 2. - In this state, the manual handle 6 is inserted to the motor shaft 2. Then, a manual switch (not shown) is pushed to energize the
release coil 19. Thus, the cam-follower lever 16 is swung clockwise to disengage thebump roller 17 from theconcave portion 15 of the cam plate so as to allow thegrooved cam shaft 5 to be rotated. - When the manual handle 6 is rotated clockwise, the
grooved cam shaft 5 is rotated counterclockwise. Thus, theroller 13 engaged with thegroove 10 of thegrooved cam shaft 5 is driven or swung leftward (inFIG 1 ), and the output shaft 11 is rotated through thelever 12 in a counterclockwise direction (direction to the "CLOSED" position). In the state after thegrooved cam shaft 5 is rotated at some degrees, thebump roller 17 is placed and rolled on the circular circumferential surface of thecam plate 14 to maintain the rotatable state of thegrooved cam shaft 5. Thelimit switch 20 detects this state to de-energize therelease coil 19. During this process (midway position), theinhibition plate 8 is engaged with thegroove 7 of the manual handle 6 to inhibit the manual handle 6 from being pulled out of the motor shaft 2. - Then, when the
grooved cam shaft 5 is rotated at about 360-degree, thebump roller 17 falls in theconcave portion 15 of thecam plate 14, and the cam-follower lever 16 is swung counterclockwise. When thegrooved cam shaft 5 is further rotated, thebump roller 17 bumps against the wall surface of theconcave portion 15 of thecam plate 14 to completely stop thegrooved cam shaft 5. Thus, theinhibition plate 8 is returned to the initial position by the spring 9 to allow the manual handle 6 to be inserted and pulled out from the motor shaft 2. - The switch operating mechanism according to the above embodiment has the following effects.
- (1) The groove of the grooved cam shaft is configured such that an axial displacement rate of the groove relative to a rotation of the grooved cam shaft is minimized around a position corresponding to each of the stop positions of the switch to prevent the output shaft from being rotated even if the motor is rotated. This makes it possible to achieve enhanced accuracy in stop position of the switch in motor operation.
- (2) The manual handle can be pulled out only if the bump roller is engaged with the concave portion of the cam plate (in this state, the output shaft cannot be rotated by the manual handle). This makes it possible to achieve enhanced accuracy in stop position of the switch (in pulling out position of the manual handle) in manual operation.
- (3) The grooved cam shaft is stopped by the bump between the bump roller and the concave portion of the cam plate. This makes it possible to eliminate the need for dynamic braking of the motor.
- (4) An axial displacement rate relative to an angle of the groove is arranged to become smaller on the side of the "CLOSED" and "EARTHED" positions and become larger on the side of the "OPEN" position. Thus, a torque conversion rate (output shaft torque/motor shaft torque) has a similar characteristic to that of a load torque of the switch. This makes it possible to maintain a load torque of the motor at an approximately constant value and reduce the load torque of the motor.
- (5) Only one limit switch is required for the stop control. This makes it possible to achieve a simplified control system.
