JP6301661B2 - Multi-position reciprocating rotary actuator - Google Patents

Description

  The invention according to the present application (hereinafter referred to as “the present invention”) relates to a reciprocating rotary actuator that outputs a rotational force that reciprocally rotates at a predetermined rotation angle, and in particular, a plurality of positions around the axis with a single output shaft ( The present invention relates to a multi-position type reciprocating rotary actuator capable of supplying a reciprocating rotational force by “multi-position”.

A general reciprocating rotary type rotary actuator supplies a rotational force that reciprocates at a predetermined rotation angle as a driving force. For example, in an ATM (automatic depositing / dispensing machine), an automatic ticket-issuing machine, or a printer device, a guide blade for distributing bills, coins, paper pieces, etc. to a predetermined transport path is incorporated as a drive source for operating. It is.
Furthermore, these devices are becoming smaller and more multifunctional year by year, and it is a matter of course that there is a demand for this compatibility for built-in parts.

  In response to this, the present applicant has previously disclosed a technique of a reciprocating rotary actuator as Patent Document 1. This provides a structure that can be reciprocally rotated at a position rotated by a predetermined angle by switching the link body and the gear meshing therewith by linearly moving in the axial direction. More specifically, when viewed from the output shaft, reciprocal rotation is performed at a predetermined rotation angle (for example, 30 °) with one radial direction as a reference (home position), and a predetermined rotation angle (from the home position is appropriately determined by a link mechanism). For example, a reciprocating rotational force having the predetermined rotational angle (for example, 30 °) is output at a position rotated about 120 °.

JP 2009-303476 A

In the above disclosed invention, by setting the meshing between the link body and the gear, at the two positions (for example, 30 ° and 120 °) that have been rotationally moved from the reference position (home position) by the single output shaft, respectively. The rotational force of reciprocating rotation was output.

  However, as described above, devices (ATMs and printers) that have been improving year by year have been developed and commercialized in a relatively short period of time in addition to space savings. There is an increasing demand for parts that can be handled and have a high degree of design freedom.

  Therefore, in view of such a demand, the present application provides a novel reciprocating rotary actuator based on a different technical idea while being based on the previously proposed reciprocating rotary actuator. When laid, the position on the output shaft that supplies the reciprocating rotational movement force on the same axis can be set to multiple relatively rotated positions, and the multi-position that increases the flexibility and versatility of the product A reciprocating rotary actuator of a type is provided.

  In order to solve the above problems, a multi-position type reciprocating rotary actuator (hereinafter referred to as “the actuator of the present application”) according to the present invention is configured as follows.

The actuator according to claim 1 of the present invention includes a drive source that axially outputs a rotational force that reciprocally rotates at a predetermined rotation angle, and is connected and separated on the same axis as the output shaft of the drive source. And a switching connection mechanism that is connected to the output shaft by rotating the shaft relatively coaxially and output means for supplying the shaft output to the outside via the switching connection mechanism. In particular, with regard to the switching connection mechanism, the rotation plate that can be connected at a plurality of rotational positions coaxial with the output shaft of the drive source, and the connection and separation between the rotation plate and the drive source. And a stopper means for stopping the rotation of the rotating plate when separated by the clutch mechanism.

Here, the “output shaft” is not limited to a shaft shaft that is normally configured as a tangible rod, but has a broad meaning that includes an assumed shaft that serves as a rotation center of a rotational force supplied from a drive source.

With this configuration of the actuator of the present application, the axial rotational force of the reciprocating rotational motion output from the driving source is output to the outside as the driving force from the output means as it is at the time of connection.

Further, the switching connection mechanism connects or separates the output shaft of the drive source and the output means, and at the time of the separation, the shaft is rotated relative to the output shaft of the drive source, and then the output means is connected again. It has an effect. Here, “relatively rotating the axis” means that only the other side is rotated on the same axis with respect to one side of the connecting portion.

The output means is for outputting rotational force to the outside, and is mainly composed of a rod-shaped shaft body (shaft). However, the present invention is not limited to this, and it may be configured by a cylinder, a flange-shaped disk, a crank, or the like.

By acting in this way, the actuator of the present application moves (referred to as “transition”) to a position where the position at the time of the re-connection is relatively rotated by a predetermined angle with respect to the previous connection position. Then, the driving force for reciprocating shaft rotation is output again. By sequentially repeating the separation from the connection, the relative shaft rotation, and the reconnection, a rotational movement is made at a predetermined angle (referred to as a “transition angle”) around the axis from a certain reference position (“home position”). A shaft rotational force (hereinafter referred to as “reciprocating rotational force”) that performs reciprocating rotational motion at a plurality of locations (“multi-position”) can be output to the outside.

Further, with the configuration of the switching coupling mechanism, the rotation plate is stopped by the stopper means at the same time as the rotation plate is separated from the output shaft of the drive source by the clutch mechanism. In this state, the output shaft of the drive source is shifted, and then the output shaft and the rotating plate are connected again. By sequentially repeating the steps of separation, transition, and reconnection from this connection, the rotation plate and the output shaft of the drive source are rotated at multiple locations relative to each other, in other words, the output of the drive source. They can be connected at a plurality of rotational positions (referred to as “transition positions”) coaxial with the shaft.

Furthermore, the clutch mechanism according to claim 2 includes an expansion biasing means (for example, an elastic material such as a coil spring, a leaf spring, or rubber) interposed between the drive source and the rotating plate, and the rotating plate as a shaft. And an operating means for moving the expansion urging means in a compressing direction.

With this configuration, the drive source and the rotating plate are separated by the repulsive elastic force of the expansion urging means. On the other hand, these connections are made by moving the rotating plate on the output shaft in the direction of the drive source by the operating means. During the movement of the rotating plate, the expansion urging means is compressed and a rebound elastic force is accumulated.

Next, the switching connection mechanism of the actuator according to claim 3 does not directly connect and separate the rotating plate and the output shaft with respect to the configuration of claim 1, but includes a switching plate. The connection / separation is performed via the. That is, a switching plate that is coaxially connected to the output shaft of the drive source, and a rotating plate that is coaxially connected to the switching plate and that can be connected and separated at a plurality of rotational positions (or transition positions) are disposed, and the switching plate A clutch mechanism that connects and separates the rotary plate and the drive source by moving an output shaft on the output shaft, and stopper means that stops the rotation of the rotary plate in accordance with the separation by the action of the clutch mechanism It is.

With this configuration, by repeating connection, separation, transition, and reconnection between the rotating plate and the switching plate, the switching plate connected coaxially with the output shaft of the drive source is connected to the rotating plate. It can be connected at multiple locations.

In addition, the clutch mechanism used in the above-described configuration is, as claimed in claim 4, extended expansion means (for example, an elastic material such as a coil spring, a leaf spring, or rubber) interposed between the drive source and the switching plate. And an operating means for moving the switching plate along the axis and compressing the expansion urging means and for connecting and separating the switching plate and the rotating plate.

With this configuration, the switching plate can be moved on the shaft by the repulsive elastic force of the expansion biasing means and connected to the rotating plate, and the rotational force of the reciprocating rotation from the drive source can be output to the outside from the output means. Then, the switching plate is moved in the reverse direction (rear direction) by the activation of the operating means, and the connection with the rotating plate is released. In the process of moving the switching plate, the expansion biasing means is compressed and a rebound elastic force is accumulated.

In addition, the configuration according to claim 5 of the present invention is characterized in that the transition angle at the time of separation by the switching coupling mechanism is set to be the same as the rotational angle of the reciprocating rotational motion of the drive source.

This is because the transition angle at the time of separation described above can be set as appropriate, but by making the transition angle the same as the reciprocation rotation angle in this way, it is an integral multiple of the reciprocation rotation angle around the output shaft. The reciprocating rotational force can be output by sequentially shifting to the position. Further, since the connection and separation are performed at the turning point in the rotational direction of the reciprocating rotation, the positioning at the time of connection and separation is ensured and the operation can be stabilized.

  As the actuating means constituting the clutch mechanism, for example, an appropriate known technique is used such as a mechanism utilizing a lever action.

  In addition, the “connection” used in the description of each claim is not a completely integrated connection in which the rotation direction is restricted in the X direction, the Y direction, but only the rotation direction that can ensure at least an integral rotation. Means a bond. Rather, in order to allow appropriate connection and separation, it is preferable that the rotating plate and the switching plate are allowed to move on the shaft.

  As an example of the connection structure of the rotating plates, a fitting structure between the recess and the protrusion may be used. In this case, the outline of the rotating plate is formed in a circular shape or a polygonal shape in which a circle is inscribed, and includes recesses (opening through holes) arranged at a plurality of positions on the circumference of a predetermined radius from the output shaft. ) And a convex portion formed on the output side of the driving source or the switching plate facing the rotating plate may be fitted.

  In the case of adopting this configuration, it is preferable to provide the concave portion on the rotating plate at a position as close to the outer peripheral edge as possible. Thereby, transmission of torque at the time of connection can be ensured.

  Since this invention is comprised as mentioned above, the output of the axial rotation of the reciprocating rotational motion from a drive source can be output at the some position rotated relatively axially, ie, several transition position. The provision of the output of the reciprocating rotational force at the plurality of transition positions can increase the degree of freedom in dealing with a multi-function embedded device and can be highly versatile.

  In the following, two specific examples (hereinafter referred to as “Example 1” and “Example 2”) as specific embodiments for implementing the actuator of the present application will be described based on the drawings.

The first embodiment will be described separately for each main configuration based on FIGS.
The actuator of the present application is functionally not limited in the direction of installation, but will be described based on the illustrated positional relationship between the top, bottom, left, and right for convenience of explanation. In FIGS. 1 to 3 and FIGS. 7 to 9, the left direction is defined as the front direction, and the right direction is defined as the rear direction.
(1) Configuration and operation of drive source

  The drive source of the first embodiment uses a rotary solenoid indicated by reference numeral 1. The rotary solenoid 1 includes an electromagnetic coil 10 attached to a rear plate 2 that constitutes a part of a housing that accommodates the whole, and a rotor 11 that is disposed with the electromagnetic coil 10 and an air gap. The rotor 11 is rotatably supported above the electromagnetic coil 10 by a rotor bearing 20 attached to the rear plate 2. The rotor 11 contains two magnets 12 that are exposed to the electromagnetic coil 10 side with different magnetic pole faces arranged side by side in the rotational direction. A back yoke 13 is abutted on the front side surface covering these two magnets 12 and 12. The rotor 11 is integrally formed with two parallel round rod-like insertion pins 14 extending in the front direction along the output shaft 3 at positions where the output shaft 3 is axisymmetric.

  Thereby, the rotor 11 reciprocates at a predetermined rotation angle around the coaxial output shaft 3 by energization control to the electromagnetic coil 10. At this time, since the output shaft 3 that is the rotation axis of the rotor 11 is located at a higher position in the drawing view, the rotor 11 exhibits a movement (swing) that causes the pendulum to swing. Such a basic structure of the rotor 11 is a well-known technique that has already been disclosed in Patent Document 1 and the like.

The rotational angle θ of the reciprocating rotation in this configuration is determined by the restriction of contact with the stopper 21 formed upright at the edge of the rear plate 2 on both sides of the electromagnetic coil 10 in a front view. The stopper 21 is formed by bending a part of the edge of the rear plate 2 in the front direction. The rotational angle θ at this time is determined by the positional relationship between the rotor bearing 20 and the stoppers 21 and 21 on both sides. In the first embodiment, this is set to be 30 degrees. In addition, although the stopper 21 of Example 1 is shape-molded with the rear plate 2 as described above, it may be formed separately. A desired rotation angle θ can be set depending on the distance between the stoppers 21 and 21 and the rotation radius of the rotor 11.
(2) Configuration and operation of the switching coupling mechanism

  Reference numeral 4 denotes a rotating plate. The rotating plate 4 has a hard disk shape, and an axial center hole 40 having a diameter that can be inserted and fitted in one end side in the rear direction of the output shaft 8 to be described later is formed at the center thereof. A key groove 41 is formed on the inner peripheral surface of the shaft hole 40 so that a key 80 described later can be fitted and inserted.

  Further, a plurality of insertion holes 42 penetrating the front and back are arranged on the plate surface of the rotating plate 4 at equal intervals on a circumference of a predetermined radius from the axis. An angle α (synonymous with the “transition angle”) formed by the distance and the radius of the insertion hole 42 is set to coincide with the rotation angle θ of the rotor 11. In the rotating plate 4 of the first embodiment, since the transition angle for one time is set to 30 degrees, the insertion holes 42 are formed at 12 locations where the circumference is equally divided at 30 degrees.

  In addition, the outline shape of the rotating plate 4 of the first embodiment may be a regular polygon or a polygon circumscribed around the circle in addition to a circle.

  With such a configuration, a pair of insertion pins 14 formed in the left and right symmetrical positions of the output shaft 3 of the rotor 11 are inserted into the corresponding two insertion holes 42 in the multiple insertion holes 42 and connected. It becomes.

  In addition, a coil spring 5 is disposed between the rotating plate 4 and the rotor 11 on the output shaft 3 as an expansion biasing means that constitutes a clutch mechanism. The coil spring 5 functions as an expansion force in a direction in which the rotating plate 4 is separated from the rotor 11.

  In addition, in the front direction of the rotating plate 4, an operating means 6 constituting a clutch mechanism is disposed. The actuating means 6 is a mechanism using a lever action (“leverage action”). The lever body 60 constituting the lever action is formed in a substantially U shape when viewed from the front, and is arranged between the rotating plate 4 and the front plate 7 in a standing manner. At the upper end portion of the lever body 60, a convex contact portion 61 is formed that contacts the vicinity of both peripheral edges in the left-right direction of the front surface of the rotating plate 4 and functions as an action point of the lever action.

  Further, the lower end portion 62 of the lever body 60 is attached to the lower portion of the front plate 7 through a frame 65 described later so as to be rotatable in the rear direction, and functions as a fulcrum for lever action.

  Furthermore, a solenoid 63 is attached and held on the front plate 7 so as to be sandwiched by a frame 65 at a position closer to the upper side than the attachment position of the lower end portion 62 of the lever body 60. The solenoid 63 includes a plunger 64 that moves back and forth (directly) in the rear direction. The direct power of the plunger 64 passes through the frame 65 and is connected to a position closer to the upper position than the fulcrum position of the lever body 60 so as to function as a power point for lever action.

  With this configuration, when the solenoid 63 is activated, the plunger 64 advances (rear direction of the arrow a) to push the lever body 60, and the contact portion 61 of the lever body 60 is pressed against the front surface of the rotating plate 4 by the lever action. Acts (arrow b). By this action, the rotating plate 4 moves in the rear direction while bending the coil spring 5 (arrow c), and the fitting pin 14 integrated with the rotor 11 is fitted into the corresponding fitting hole 42. As a result, the rotating plate 4 is connected to the rotor 11 and rotates integrally on the same axis.

Next, when the plunger 64 is returned (moving in the front direction of the arrow a), the pressure on the rotating plate 4 is released, and the rotating force of the coil spring 5 opposes this to move the rotating plate 4 in the front direction. (Arrow d). Thereby, the insertion pin 14 is pulled out from the insertion hole 42, the connection between the rotor 11 and the rotating plate 4 is released, and a separated state is obtained.
(3) Configuration and operation of output means

  Reference numeral 8 denotes an output shaft constituting the output means. The main body of the output shaft 8 has a round bar shape, is supported in a penetrating manner by a front bearing 71 attached to the front plate 7, and is arranged coaxially with the output shaft 3 of the rotor 11. A substantially U-shaped key 80 extending in the rear direction is integrally formed at the rear end of the output shaft 8.

Furthermore, a stopper pin 72 that can be fitted is provided on the upper portion of the front plate 7 so as to protrude in the rear direction at a position corresponding to at least one fitting hole 42 of the rotating plate 4. The stopper pin 72 is for fitting into the fitting hole 42 to stop the rotating plate 4. Therefore, as long as the rotating plate 4 can be stopped and held, other configurations are possible without being limited thereto. For example, as in Example 2 to be described later, the rotating plate 4 has a regular polygonal shape and sandwiches the peripheral side portion, or a plate surface is formed with a large number of convex portions and notch portions for friction and engagement. It is good also as a structure which stops by a joint (illustration omitted).
In addition, in Example 1, although it is set as the single stopper pin 72, it is not limited to this.
(4) Operation and effect as a whole of Example 1

The first embodiment configured as described above operates as follows. Note that the operation of each mechanism and operating means has already been described, and will be omitted.
As shown in FIG. 5, the actuator of the present application is characterized by a plurality of positions shifted in units of a predetermined transition angle α from a specified reference position (referred to as “home position (HP)”) in a front view of the output shaft 3. (Referred to as “multi-position”) is to output the rotational force of the reciprocating rotational motion at the rotational angle θ to the outside as a driving force. The action of this position transition is called “mode switching”.
a. Output of rotational force by connection

As shown in FIG. 2, the rotating plate 4 moves in the rear direction (arrow c) by the activation of the solenoid 63 and the action of the lever body 60, and is connected to the rotor 11. In this process, since the key 80 of the output shaft 8 slides in the key groove 41 of the rotating plate 4 but does not come off the key groove 41, the output shaft 8 and the rotating plate 4 are maintained in a connected state. doing. In this state, the rotor 11, the rotating plate 4, and the output shaft 8 rotate integrally on the same axis, and the reciprocating rotational force from the rotor 11 is output as it is.
b. Mode switching by disconnection

Next, as shown in FIG. 3, when the solenoid 63 is stopped and the plunger 64 is returned (moving in the front direction), the pressing load on the rotating plate 4 of the lever body 60 disappears, and the repulsive force of the coil spring 5 ( The rotating plate 4 moves in the front direction by the expansion force (arrow d). The rotating plate 4 that has moved stops rotating when the stopper pin 72 is inserted into the insertion hole 42. The rotor 11 released from the connection with the rotating plate 4 is allowed to reciprocate by itself.
c. Position shift by mode switching

  Next, with reference to FIG. 6, the transition of the position by the mode switching by the above action will be described step by step.

  First, as shown in [HP-1] and [HP-2] in FIG. 6, in the state of the home position, the insertion pin 14 of the rotor 11 is inserted into the opposite insertion hole 42 of the rotating plate 4 (shown in black). The stopper pin 72 is removed from the rotating plate 4 (illustrated in white), and the rotor 11, the rotating plate 4, and the output shaft 8 rotate together. The rotation angle θ of the reciprocating rotation at this time is defined by contact with the stoppers 21 provided on both sides of the rear plate 2. In the first embodiment, the rotation angle θ is set to 30 degrees.

  Next, as shown in [M-1] in FIG. 6, the rotation of the rotor 11 is first stopped while the rotor 11 is in contact with the right stopper 21R. Then, due to the lever action described above, the rotating plate 4 moves in the front direction (frontward as viewed in FIG. 6), and the stopper pin 72 is inserted into the opposed fitting hole 42 of the rotating plate 4 (shown in black) and stopped. . Along with this, the insertion pin 14 of the rotor 11 is extracted from the insertion hole 42 (shown in white). In this state, since the rotor 11 is allowed to rotate independently, only the rotor 11 is rotated clockwise (arrow e) until it hits the left stopper 21L as shown in [M-2] in FIG. The rotation angle at this time is the rotation angle α of the rotor 11 (30 degrees in the first embodiment).

  Next, in this state, when the rotating plate 4 is moved in the rear direction (backward direction as viewed in FIG. 6), the stopper pin 72 is detached from the rotating plate 4 (shown in white), and at the same time, the insertion pin 14 of the rotor 11 is inserted. Is inserted into the opposite insertion hole 42 (shown in black), and the rotating plate 4 and the rotor 11 are reconnected. Thereby, the reciprocating rotational force is output from the output shaft 8 at the position shifted to the next position (“2nd. Position”) ([SP-1] and [SP-2] in FIG. 6). This 2nd. The position is a position shifted from the home position by θ (30 degrees in this embodiment) in the counterclockwise direction as viewed in FIG.

  By sequentially switching the modes through such a process, it is possible to shift to a desired position and output a reciprocating rotational force. The transition angle α of this position is normally set to be the same as the rotation angle θ of the rotor 11, but is further subdivided by stopping the rotor 11 at a position other than the contact position of the left and right stoppers 21 (for example, an intermediate position). It is also possible to set the transition angle α. Incidentally, in Example 1, since the transition angle α is selected to be 30 degrees, there are 12 positions for outputting the rotational force of the reciprocating rotation.

Next, Example 2 will be described.
In the second embodiment, the technical idea of the actuator of the present application is realized in the same manner as the first embodiment, but a further component is added to the operation mechanism of the clutch mechanism of the first embodiment. The outline is that a switching plate 200 is newly provided, and mode switching is performed by moving the switching plate 200 coaxially with the output shaft 3 in place of the rotating plate 4 of the first embodiment.

7-11 is the figure shown regarding Example 2. FIG. In the following description, components having the same functions as those in the first embodiment are denoted by the same reference numerals as those used in the first embodiment, and detailed description thereof is omitted to avoid redundant description.
(1) Configuration of drive source

The basic configuration of the rotary solenoid 100 of the second embodiment is the same as that of the first embodiment, but has a different configuration in that a rotor shaft 110 is provided at the rotation center of the rotor 11. This is to secure the holding and moving axis of the switching plate 200, which will be described later, on the output shaft. Other configurations of the rotor 11, the fitting pin 14, and the rear plate 2 and their operations are the same as those in the first embodiment.
(2) Configuration and operation of the switching mechanism

  A switching plate denoted by reference numeral 200 is hard and has a rectangular plate shape, and an insertion hole 210 having a diameter through which the rotor shaft 110 can be fitted is formed at the center. Further, an insertion tube 211 having an opening diameter and a sliding distance through which the insertion pin 14 of the rotor 11 can be inserted at a symmetrical position across the insertion hole 210 is integrally formed on the rear plate surface of the switching plate 200. Is formed. Further, a connecting pin 212 having an outer diameter that can be inserted into the insertion hole 410 of the rotating plate 400 is integrally formed on the plate surface in the front direction of the switching plate 200 at a vertically symmetrical position across the insertion hole 210. ing.

  The rotary plate 400 used in the second embodiment has a hard plate shape, and a large number of insertion holes 410,... Are formed on the plate surface at equal intervals on the circumference as in the first embodiment. . The outline of the rotating plate 400 is a regular polygon (a regular dodecagon in the second embodiment). The number of corners coincides with the number of the insertion holes 410, and the corners are formed in the radial direction through which the insertion holes 410 pass. In addition, the rotating plate 400 of the second embodiment has the output shaft 8 extending in the front direction integrally attached and fixed to the shaft center thereof, and is rotatably supported by the front bearing 71. The corresponding connecting pin 212 of the switching plate 200 is fitted into and connected to the insertion hole 410.

  Actuating means 600 constituting a clutch mechanism is disposed between the rotating plate 400 and the switching plate 200. Similar to the first embodiment, the operating means 600 has a configuration that functions by lever action.

  Under the rotating plate 400, a stopper body 620 having a substantially U-shape is arranged in an upright manner. The stopper body 620 is mainly composed of a sandwiching portion 621 (standing state in the drawing) made of a parallel body constituting a part of the U-shape, and the interval between the stopper bodies 620 is a regular polygonal outline shape. In this case, the distance between the opposite sides is set. Further, on the rear side of the lower end portion of the sandwiching portion 621, a wedge body 622 having a slope inclined downward in the rear direction is integrally formed at the upper portion.

  As a configuration of the lever operation, one end side (front end portion) of the link lever 610 is pivotably coupled to the lower end portion of the stopper body 620 (“link coupling”) to function as an operation point.

Further, the other end side (rear direction end portion) of the link lever 610 is attached and fixed to the lower portion of the rear plate 2 and is linked by a frame 630 so as to function as a fulcrum for lever action.
Further, in the vicinity of the lower end portion of the rear plate 2, a solenoid 63 with the linear movement direction of the plunger 64 facing upward is mounted on a base plate 640 whose lower end edge portion is bent and covered with the frame 630. And fixed. The plunger 64 advances and retreats through the frame 630 and acts on the intermediate portion of the link lever 610 to function as a lever point of leverage.

  With the above configuration, as shown in FIG. 8, when the solenoid 63 is activated, when the plunger 64 rises and advances and pushes up the one end side of the link lever 610, the stopper body 620 that is linked with the link lever 610 rises vertically by lever action. . In accordance with this, the holding portion 621 of the stopper body 620 comes into contact with and slides on the opposing outer peripheral side surfaces of the rotating plate 400 (“holding”). As this rises, the wedge body 622 integral with the stopper body 620 intervenes between the rotating plate 400 and the switching plate 200 and pushes it apart to separate them from each other. This separation distance is determined by the thickness of the wedge body 622, and the thickness is set to a distance at which the connecting pin 212 of the switching plate 200 can be completely extracted from the insertion hole 410 of the rotating plate 400.

  As a result, the switching plate 200 slides in the rear direction while bending the coil spring 5 on the rotor shaft 110. At this time, the expansion repulsive force is accumulated in the coil spring 5.

On the other hand, as shown in FIG. 9, when the activation of the solenoid 63 is stopped and the plunger 64 is returned (lowered), the stopper body 620 is lowered and separated from the rotating plate 400 by the opposite action of the lever action. Then, the rotating plate 400 is released from the stopped state. At the same time, the interposition of the wedge body 622 is eliminated, and the force for separating the rotating plate 400 and the switching plate 200 is eliminated. Opposing to this, the coil spring 5 is repelled and an expansion force is applied, and the connecting pin 212 of the switching plate 200 is fitted into the fitting hole 410 of the corresponding rotating plate 400. In this case, even if the switching plate 200 moves, the insertion pin 14 of the rotor 11 stays in the long insertion tube 211 and does not come off.
(3) Configuration and operation of output means

In the output shaft 8 constituting the output means in the second embodiment, the main body forms a rod-like body as in the first embodiment, and is fixedly attached integrally to the shaft center of the rotating plate 400. By the front bearing 71, The rotor shaft 110 is supported coaxially with the output shaft 3. The output shaft 8 transmits and outputs the rotation of the rotating plate 400 as it is.
(4) Operation and effect as a whole of the position of the configuration of the second embodiment

  Next, with reference to FIG. 11, the transition of the position by mode switching in the second embodiment will be described step by step.

  First, as shown in [HP-1] and [HP-2] in FIG. 11, in the home position state, the connecting pin 212 of the switching plate 200 that rotates integrally with the rotor 11 is inserted into the insertion hole 410 of the rotating plate 400 ( Then, the stopper body 620 descends and disengages from the rotating plate 400, and the rotor 11, the switching plate 200, the rotating plate 400, and the output shaft 8 rotate together. At this time, the rotation angle θ of the reciprocating rotation is defined by contact with the stoppers 21 on both sides of the rear plate 2. This angle θ is set to 30 degrees as in the first embodiment.

  Next, as shown in [M-1] in FIG. 11, the rotor 11 is stopped in a state where the rotor 11 is swung to the right as viewed from the front, and the stopper body 620 raised by the lever action is opposed to the rotating plate 400. Stop rotation by pinching the sides. At the same time, the wedge body 622 of the stopper body 620 is inserted between the rotating plate 400 and the switching plate 200, and the connecting pin 212 is pulled out from the insertion hole 410. In this state, only the rotor 11 and the switching plate 200 can rotate together. Here, as shown in [M-2] in FIG. 11, the rotor 11 and the switching plate 200 are rotated clockwise (arrow e) until they abut against the left stopper 21L. The rotation angle at this time is the rotation angle α of the rotor 11 (30 degrees in the second embodiment).

  Next, when this state is maintained and the stopper body 620 is lowered, the holding of the rotating plate 400 is eliminated, and the caulking wedge body 622 is also lowered simultaneously, so that the rotating plate 400 and the switching plate 200 are reconnected. . As a result, the reciprocating rotational force is output from the output shaft 8 at the position shifted to the next position (“2nd. Position”) (FIG. 11 [SP-1] and [SP-2]). In this case, 2nd. The position is a position shifted counterclockwise by θ (30 degrees in this embodiment) from the home position as viewed in FIG.

  By repeating the mode switching through such a process, it is possible to output the reciprocating rotational force at each of a plurality of locations (multi-position).
