[Industrial applications]

 According to the present invention, a decorative body incorporated in a facility clock such as a clock tower is usually stored in the facility clock, and the door is opened at each required time so that the decorative body appears from the facility clock to set the stage. The present invention relates to an equipment clock to be formed, and more specifically to a mechanism for changing the direction of a doll as a decorative body incorporated in the stage.

[0002]

[Prior art]

 Today, every hour or so, the door is opened with music in time with the hourly clock, and a decorative body such as a doll incorporated in the inside of the equipment clock appears to form a stage, after which this decorative body is formed. Many equipment clocks such as clock towers have been installed to attract people's attention by moving.

In such equipment clocks, in many cases, a decorative object such as a doll is placed on a rotary table, and the rotary table is rotated to move the decorative body. There was a model in which a doll or the like was made to appear from inside (for example, Japanese Utility Model Laid-Open No. 63-50090, Japanese Utility Model Laid-Open No. 131191, and Japanese Patent Laid-Open No. 2-141693). In addition, recently, we decided to incorporate as many decorations as possible into the stage to create a stage by squeezing out the decorations installed inside the equipment clock, and the doors that hide the decorations so that they are usually invisible. When the opening / closing door is opened by attaching a decoration to the inside of the door, the stage is expanded with the decoration attached to the inside of the opened door to change the opening / closing door from the closed state to the opening / closing door. There is one in which a large amount of various ornaments are incorporated in the limited space of the equipment timepiece as much as possible (for example, JP-A-2-31186).

In a conventional large-scale equipment clock, a space is usually formed inside a clock body or a clock tower, and as many decorations as possible are stored in this space and stored when the door is opened. The stage was formed by pushing out decorative objects such as dolls. Furthermore, when the door is opened, there is a limit to the internal space such as the clock tower, even though it is necessary to store as many decorative elements as possible as large as possible to form a large stage. In order to improve the appearance of the decorative body to be shown in the open state, the shape and arrangement of the decorative body must be determined in advance, so in order to increase the size of the decorative body to be stored to the limit, There is also one that makes it possible to install a doll as large as possible while changing the orientation of the doll provided on the back side of the door when the door is opened so that there is no wasted space inside the clock tower during storage. .

As described above, in the stage provided with the dolls whose direction is changed, as shown in FIGS. 3 and 4, the left and right doors 51 are provided with dolls 15 and 65, respectively, and as shown in FIG. Of the human figures 15, 65, for example, one doll 15 is provided with a limit switch 47 for detecting the right rotation limit position, a limit switch 48 for detecting the left rotation limit position, and a limit switch 49 for detecting the front position. Control whether the forward rotation voltage or the reverse rotation voltage is applied simultaneously with the on / off control of the current supplied from the power supply sequence circuit 41 to each motor 21 by the position detection signals from the limit switches 47, 48, 49. However, the voltage from the power supply sequence circuit 41 is commonly applied to the drive motors 21 of the dolls 15 and 65.

When the respective motors 21 for rotating the left and right dolls 15 and 65 are rotated normally or reversely to rotate the doll 15 provided on the right door and the doll 65 provided on the left door in opposite directions, In addition to the case where the connection to the motor is crossed to reverse the rotation direction of the motor itself, there are also cases where the rotation direction of the doll is reversed due to the intermediate gears 13, 63 between the motor and the doll.

[0007]

[Problems to be solved by the device]

 When changing the orientation of the dolls attached to the left and right doors, the forward rotation drive voltage and the reverse rotation drive voltage are simultaneously applied to the doll rotation drive motor installed on the right door and the doll rotation drive motor installed on the left door, respectively. If the doll does not have the position detection switch, the doll does not turn in the correct direction and stops if the doll does not have a position detection switch if it is used repeatedly for a long period of time due to variations in the torque of each motor. Sometimes there were cases.

[0008]

[Means for Solving the Problems]

 The present invention uses a drive motor having a power input terminal and a forward / reverse switching control input terminal to change the direction of a doll, and detects the right rotation limit position, the left rotation limit position, and the front position of the doll. A limit switch is provided, and the output terminals of the limit switches provided at the right rotation limit position and the left rotation limit position are connected to the forward / reverse switching control input terminals of the drive motor, and the limit switch output terminals provided at the front position are connected to the power source. Connect to the position detection signal input terminal of the sequence circuit.

[0009]

【Example】

 As shown in FIG. 1, the embodiment according to the present invention has a first input 23 and a second input 25 for forward rotation, and a first input 23 and a third input 27 for reverse rotation. A geared motor in which a control unit 31 is integrated with a motor body 22 is used, and the control unit 31 has a first control input terminal 33 and a second control input terminal 35 as a forward / reverse switching control input terminal. When a control signal is input to the control input terminal 33, the power supply line 45 is connected. The power input terminal 37 is connected to the first input 23 and the second input 25 of the geared motor, and the control signal is input to the second control input terminal 35. Is input, the power input terminal 37 is connected to the first input 23 and the third input 27 of the motor main body 22, and the forward / reverse rotatable geared motor having the control unit 31 is used as the drive motor 20. And the output of this drive motor 20 Is intended to rotate the rotary table 10 mounted with the motor for operating the neck and hand puppet 15 and doll 15 by a gear 13 attached to.

The geared motor is a small-sized drive motor that has a gear head for reduction of communication integrally with the motor main body 22 and can obtain a high torque output. Further, a capacitor is inserted between the second input 25 and the third input 27 of the drive motor 20 in the control unit 31 to absorb the counter electromotive force when switching between normal rotation and reverse rotation. .

Then, the rotation table 10 on which the doll 15 and the like are mounted is provided with a position detecting projection 11, and the rotation table 10 is rotated to bring the actuator lever into contact with the position detecting projection 11 for detecting a right rotation limit position. A limit switch 47, a left rotation limit position detection limit switch 48, and a front position detection limit switch 49 are provided. For example, the output terminal of the right rotation limit position detection limit switch 47 is the first control input terminal 33 of the control section 31. The output terminal of the limit switch 48 for detecting the left rotation limit position is connected to the second control input terminal 35 of the control section 31, and the output terminal of the limit switch 49 for detecting the front position is the position of the power sequence circuit 41. It is connected to the detection signal input terminal.

In this embodiment, as the front position detecting limit switch 49, a limit switch that outputs a detection signal when the actuator lever is pressed in one direction is used. When the projection 11 for movement contacts the actuator lever while moving to the right, although the detection signal is output from the limit switch 49 for front position detection, the projection 11 for position detection moves to the left and the actuator lever moves. When it comes into contact with the front position detection limit switch 49, the limit switch 49 does not output a detection signal.

The embodiment shown in FIG. 1 uses two such rotating mechanisms, and drives the doll 15 provided on the right door 51 and also drives the doll 65 provided on the left door 51. It is to rotate at the same time. Therefore, in this embodiment, when the power supply line 45 from the power sequence circuit 41 to the control unit 31 is energized, one of the turntables 10 starts to rotate to the right, for example, set in the control unit 31, and the other one. The rotary table 60 starts rotating to the left, for example, and when the position detecting projection 11 provided on the former rotary table 10 comes into contact with the actuator lever of the right rotary limit position detecting limit switch 47, the drive motor 20 rotates. When the position detection projection 11 is automatically switched to the reverse rotation and contacts the actuator lever of the front position detection limit switch 49 while moving to the left, the front position detection limit switch 49 does not output a detection signal. The position detection protrusion 11 goes beyond the front position and is positioned on the actuator lever of the left rotation limit position detection limit switch 48. When the detection projection 11 comes into contact, the rotation of the drive motor 20 is automatically returned to the normal direction again, and when the position detection projection 11 contacts the actuator lever of the front position detection limit switch 49, the front position detection limit is reached. Since the switch 49 outputs a detection signal, the rotation of the drive motor 20 is stopped when the power output from the power sequence circuit 41 is stopped by this detection signal. Similarly, in the other rotary table 60, the position detection projection 11 is reciprocated within the range of the left rotation limit position detection limit switch 98 and the right rotation limit position detection limit switch 97 by passing a current through the power supply line 95. When the position detecting projection 11 comes into contact with the actuator lever of the front position detecting limit switch 99, the current output from the power supply sequence circuit 41 to the power supply line 95 is cut off. Also stops rotating.

As described above, when a current is passed from the power supply sequence circuit 41 to the power supply line 45, for example, the rotary table 10 is controlled within a range limited by the right rotation limit position detection limit switch 47 and the left rotation limit position detection limit switch 48. And the doll 15 placed on the rotary table 10 automatically reciprocates, and as shown in the graph of FIG. 2, the doll 15 is directed from the front position, for example, to the right side, then to the left side, and then to the front side. The dolls 15 and 65 are provided with the control units 31 and 81, respectively, and the driving motors 20 and 70, the right rotation limit position detection limit switches 47 and 97, and the left rotation limit position. Since the detection limit switches 48 and 98 are provided, the dolls 15 and 65 are surely turned to the right rotation limit and the left rotation limit, respectively, and the forward and reverse rotations are controlled. Since the drive motors 20 and 70 in which the control units 31 and 81 are integrated with the motor bodies 22 and 72 are used, the signals from the front position detection limit switches 49 and 99 cut off the power supply from the power sequence circuit 41. It is possible to control the operations of the dolls 15 and 65 only by controlling the dolls and to operate the dolls 15 and 65 by simplifying the power supply sequence circuit 41.

Therefore, as shown in FIGS. 3 and 4, a plurality of dolls having this drive mechanism are attached to the left and right doors 51, respectively, and the dolls 15 and 65 are rearward with respect to the door 51. In order to make the dolls 15 and 65 face toward the ornament body 55 or toward the viewer in front of the clock tower 50, it is necessary to ensure that each doll 15, 65 is at the angle set by the limit switch. The drive motor 20 that can be oriented in the direction of the arrow and has the power source input terminal 37 and the first control input terminal 33 and the second control input terminal 35 as the forward / reverse switching control input terminals by integrating the control unit 31. Since this is used, it is possible to make the rotation driving mechanism compact and simple.

In the drive motor 20 with the control unit 31 integrated, when a control signal is input to the control signal input terminals 33 and 35 to switch the rotation direction, a torqueless state of about 0.5 seconds occurs. Therefore, when the direction of rotation is reversed at this position toward the central decorative body 55, or when the direction of rotation is reversed at this position when the direction of rotation is reversed, a rotation stop period is generated. By tilting the neck or upper body when the rotation is stopped, it is possible to bow toward the central ornamental body 55 and toward the viewer.

Further, as shown in FIG. 4, the direction of the doll 15 placed on the rotary table 10 and rotated is set in a timepiece tower 50 as shown in FIG. When storing, a voltage is applied to the power input terminals 37 and 87 of the required driving motors 20 and 70 for the dolls 15 and 65 in accordance with the closing operation of the door 51, and the right rotation limit position detecting limit switch 47 and By the detection signal from the limit switch 98 for detecting the left rotation limit position, the voltage applied from the power lines 45 and 95 to the control units 31 and 81 is cut off, and the closing operation of the door 51 is completed. It can also be stored inside the clock tower 50 in a turned state.

Further, the doll 15 has a motor for actuating a hand in addition to the drive motor 20 for changing the direction in which the turntable 10 is rotated, and in addition to changing the direction of the doll 15, a handbell held in the hand. It is a movement for rocking 17 or the like. The doll whose rotation is controlled by this rotation mechanism is not limited to the case where it is attached to the door 51, and the rotation mechanism can also be used as a mechanism for rotating the doll which is the central ornamental body 55 left and right. Also, the dolls 15 and 65 are not limited to being placed on the rotary tables 10 and 60, but a doll with a built-in motor for actuating the neck and hands is supported by a rod-shaped rotary shaft, and the rotary shaft is used to detect an appropriate position. The rotation mechanism can be used by providing the protrusion 11.
