Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention is to drive an air cylinder by turning on / off a switch means according to the magnitude of an electric signal corresponding to a sound, and thus to apply a load. Concerning the Karakuri doll that was made to work.

(Prior Art) Conventionally, as a so-called Karakuri doll for entertaining a viewer by, for example, operating various parts in various ways, each part is provided with a drive mechanism such as an air cylinder, and these drive mechanisms are provided with a simple sequence circuit. There is provided a device which is selectively ON / OFF controlled and driven.

(Problems to be solved by the invention) However, since such a karakuri doll only operates uniformly according to a sequence circuit, for example, it depends on the rhythm of music or the volume of a sound such as a human voice. It wasn't something that would make the viewer even more interested by operating it.

As a means for realizing the Karakuri doll that operates according to the loudness of the sound as described above, a microcomputer is used, and a program of operation corresponding to the rhythm of the music to be used is created and based on this program. It is conceivable to control the drive mechanism of each part, but in this case, in addition to the expensive microcomputer, it costs a lot of money such as having to create a program each time according to the music to be used, Unlike an industrial robot or the like, a control device for a Karakuri doll, which does not require highly precise control, has a large economic burden and cannot be a practical means.

The present invention has been made in view of the above circumstances, and an object thereof is a simple and inexpensive Karakuri doll having a configuration capable of changing the operation of a load according to the volume of a sound such as music or human voice. To provide.

[Means for Solving the Problem] (Means for Solving the Problems) A karakuri doll according to the present invention comprises an electromagnetic solenoid attached to a base frame to which an electric signal according to sound is given, and a return spring attached to the base frame. A plunger that is supported by the return spring and is attracted and moved by the electromagnetic solenoid according to the magnitude of the electric signal; and a plunger that is inserted into and engaged with the plunger in a loosely fitted state through a long-hole-shaped connecting portion. The moving member, the switch means that is turned on and off according to the movement of the operating member, and the forward and backward moving strokes of the piston rod that drives the load according to the on / off time of the switch means. It is characterized by having a changing air cylinder.

(Operation) According to the Karakuri doll of the present invention, when an electric signal corresponding to a sound is given to the electromagnetic solenoid, a magnetic flux according to the magnitude of the electric signal is generated in the electromagnetic solenoid. When the plunger supported by the return spring repeats the movement of suction and return, and the connecting part moves according to this movement of the plunger, it engages in the loose fitting state with respect to the presence or absence of an electrical signal corresponding to a small sound. The actuated member does not move, so-called chattering can be prevented, and the amount of movement of the connecting portion increases to move the actuating member depending on the presence or absence of an electric signal corresponding to a loud noise. The switch means is turned on. Then, the forward stroke of the piston rod of the air cylinder is changed according to the ON time at that time,
When it is turned off, the backward movement stroke of the piston rod of the air cylinder is changed according to the off time. As a result, the load is driven by the piston rod so as to perform various operations according to the magnitude change and the time change of the electric signal according to the sound.

The plunger 5 is moved downward by the attractive force of the electromagnetic solenoid 4, and is held at the upper return position by the urging force of the return spring 7 when the attractive force does not work. Reference numeral 8 denotes a micro switch, which is a switch means fixed to the right side of the mounting plate 3, and has a terminal 8
It has a and 8a. A push button 8b is provided on the upper surface of the micro switch 8 so as to project upward, and
A pivot portion 9 is formed on the right side of the push button 8b. Reference numeral 10 denotes a long actuating member composed of a wire spring, the base end 10a of which is pivotally supported by the pivot 9 to contact the push button 8b, and the free end 10b of which is loosely inserted into the connecting member 6. ing. The actuating member 10 holds the micro switch 8 in the off state when the plunger 5 is in the return position, and presses the push button 8b to turn the micro switch 8 in the on state when the plunger 5 is sucked and moves downward. It is supposed to do.

The connecting member 6 connects the plunger 5 and the return spring 7, and at the same time, the plunger 5 and the operating member 10 are connected.
It is also used as a connecting part for connecting and.

Next, the configuration of the input side of the sound discriminator 11 will be described with reference to FIG. Reference numeral 12 denotes a stereo amplifier that outputs an electric signal according to sound, a tape deck 13 as a sound source is connected to this input terminal, and a speaker 14 is provided at the R side (right side) output terminal of the speaker output terminals. Is connected, L
Both terminals of the electromagnetic solenoid 4 are connected to the side (left) output terminal.

Now, the configuration on the output side of the sound discriminator 11 will be described with reference to FIG. Reference numerals 15 and 16 denote driving power supply terminals, and a power supply switch 17, the microswitch 8 and an exciting coil 19 of the solenoid valve 18 are connected in series between these terminals 15 and 16 to form an electric circuit. There is. The solenoid valve 18 has an inflow port 20 connected to an air compressor 21, and an on-time outflow port 22 and an off-time outflow port 23 are connected to an extruding inflow port 25 and a drawing inflow port 26 provided in an air cylinder 24 serving as a drive mechanism. The compressed air flowing from the air compressor 21 to the inflow port 20 is guided to the on-time outlet 22 when the exciting coil 19 is energized, and to the off-time outlet 23 when the power is cut off. . The air cylinder 24 is built into the part that operates the hands of a Karakuri doll that plays a guitar (not shown).
This includes a piston 28 inserted in a cylindrical cylinder 27 so as to be capable of reciprocating in the axial direction, and a piston rod 29 having a tip portion penetrating one end surface of the cylinder 27 and protruding outward. When the compressed air flows into the cylinder 27 from the extrusion inlet 25, the pressure moves the piston 28 to the right to push out the piston rod 29, and the compressed air flows into the cylinder 27 from the inlet 26. Piston 28
Is moved to the left to retract the piston rod 29.

Next, the operation of this embodiment will be described.

First, the power switch 17 is turned on and the air compressor 21 is operated. In this state, since the micro switch 8 is off and the exciting coil 19 is not energized, the compressed air of the air compressor 21 passes through the off-time outlet 23 of the solenoid valve 18 and the inlet 26 of the air cylinder 24 to the cylinder. 27, the piston rod 29 is held in the original position shown in the drawing retracted to the left, so that the hand of the karakuri doll is held in the initial position before the action of playing the guitar.

Then, when a tape containing music is set on the tape deck 13 and operated together with the stereo amplifier 12, the stereo amplifier 12 gives an electric signal of a magnitude corresponding to a musical sound to the speaker 14 from the R side output terminal, Moreover, the L-side output terminal is applied to the electromagnetic solenoid 4. This causes the speaker 14 to generate a musical sound, and the electromagnetic solenoid 4 to generate a magnetic flux according to the magnitude of the applied electric signal. Then, the plunger 5 is sucked and moved downward when the suction force by the magnetic flux becomes larger than the biasing force of the return spring 7, but when the movement amount is small, the operating member 10 becomes the connecting member 6. Since it is provided in the loosely fitted state, it does not move and chattering can be prevented. When the moving amount of the plunger 5 increases and the connecting member 6 comes into contact with the operating member 10, the operating member 10 is rotated downward to press the push button 8b and turn on the micro switch 8. . As a result, the exciting coil 19 is energized, the solenoid valve 18 allows the compressed air of the air compressor 21 to flow out from the on-time outlet 22, and the piston 28 of the air cylinder 24 moves from the extrusion inlet 25 to the cylinder 27. It moves to the right by the pressure of the inflowing compressed air, and accordingly the piston rod 29 is pressed to the right, so that the hand of the Karakuri doll will move to play the guitar.

Then, after that, when the electric signal from the stereo amplifier 12 decreases and the attraction force of the plunger 5 by the electromagnetic solenoid 4 decreases, the plunger 5 causes the return spring 7 to return.
The micro switch 8 is turned off by returning to the return position by the urging force of. As a result, the exciting coil 19 is cut off,
The solenoid valve 18 allows the compressed air of the air compressor 21 to flow from the off-time outlet 23, and the piston 28 of the air cylinder 24 moves to the left by the pressure of the compressed air flowing in from the inlet 26 for piston rod. 29 is retracted to the left, so that the hand of the Karakuri doll is returned to the initial state before playing the guitar.

Then, such an operation is repeated according to the magnitude of the electric signal supplied from the stereo amplifier 12. In this case, when the on time or off time of the micro switch 8 changes according to the magnitude of the electric signal given from the stereo amplifier 12, the movement stroke of the piston rod 29 of the air cylinder 24 to the right or left moves for that time. It will change in proportion to. As a result, the hand of the Karakuri doll can be delicately moved according to the content of the music recorded on the tape.

According to this embodiment, the following effects can be obtained.

That is, when an electric signal of a musical sound is given to the electromagnetic solenoid 4 from the stereo amplifier 12, the magnetic flux generated according to the magnitude of the electric signal causes the plunger 5 suspended by the return spring 7 to be sucked down and returned. Raise
For the presence or absence of an electric signal corresponding to a low sound, the actuating member 10 engaged with the connecting member 6 in a loosely fitted state is not moved, and the micro switch 8 is held in the off state to prevent chattering. The micro switch 8 is turned on and off depending on whether or not there is an electric signal according to the above. Therefore, the air cylinder 24 incorporated for the movement of the hand of the karakuri doll that plays the guitar has a large size, such as when hitting a rhythm. It is possible to push the guitar rod out by pushing the piston rod 29 against a musical sound, and pull back the piston rod 29 when there is no musical tone or a small musical tone to return to the initial state. . Therefore, control of the movement of the Karakuri doll corresponding to the volume of the musical sound is controlled by the electromagnetic solenoid 4,
The combination of the plunger 5, the return spring 7 and the micro switch 8 can be realized by using the inexpensive sound discriminator 11 with a simple structure.

Further, since the micro switch 8 is turned on and off by moving the plunger 5 suspended by the return spring 7, even if the same on operation is performed, the stereo amplifier
The larger the electric signal from 12, the longer the return time of the plunger 5 and the longer it is on, so the time to push out the piston rod 29 of the air cylinder 24 becomes longer,
Thus, the movement of the hand of the karakuri doll can be increased, and conversely, for a small electric signal, the on-time is shortened, and the hand of the karakuri doll makes a small movement. In addition to the difference in the ON time of the micro switch 8 depending on the magnitude of the electric signal as described above, the ON timing depending on the generation timing of the electric signal also varies, so that the piston rod 29 of the air cylinder 24 is not changed. An action such as pushing out again is performed during the process of returning to the position, and the hand of the Karakuri doll moves in a complicated manner in a state that matches the music.

Furthermore, since the electric signal corresponding to the sound is given by the stereo amplifier 12, unlike the case of controlling the Karakuri doll by a microcomputer, it is not necessary to create a program each time, and the tape deck 13 used as a sound source can be arbitrarily set. You can control the movement of the Karakuri doll just by setting the tape that contains the music.

Although the micro switch 8 is used as the switch means in the above embodiment, the present invention is not limited to this, and another mechanical switch may be used, for example, a light emitting / receiving element is used to move the plunger 5. A photoelectric switch that turns on and off by blocking light to the light receiving element may be used.

Further, in the above-mentioned embodiment, the stereo amplifier 12 and the tape deck 13 are used to give an electric signal according to the sound, but the present invention is not limited to this, and for example, a record player or a microphone may be used to generate the sound. Any device that converts into an electric signal may be used.

Further, in the above embodiment, the hand of the karakuri doll that plays the guitar as the object to be controlled is described, but the invention is not limited to this. The solenoid valve can be applied to multiple parts at the same time, not just one.
Other solenoid valves may be connected in parallel to 18, or a switching device may be provided to distribute electric signals to the plurality of solenoid valves one after another so that a plurality of parts operate one after another. Various modifications are possible without departing from the scope.

[Effect of the Invention] As described above, in the Karakuri doll of the present invention, when the electromagnetic solenoid is applied with an electric signal according to the sound, the plunger supported by the return spring is moved according to the magnitude of the electric signal. When the switch means is turned on and off by the actuating member via the connecting portion according to the movement amount of suction and return, the reciprocating movement stroke of the piston rod of the air cylinder is changed corresponding to the on / off time. As a result, the switch means is turned on / off depending on the magnitude of the electrical signal of the sound, and the forward movement stroke and the backward movement stroke of the piston rod of the air cylinder are changed in accordance with the on / off time. It is possible to manufacture, and it is only necessary to give an electric signal corresponding to any sound to the electromagnetic solenoid. Unlike a computer, it has an excellent effect that it is not necessary to create a program according to a sound.
