Description

Detailed Description of the Invention

The present invention relates to a music box automatic winding performance apparatus, and in particular, an electric motor is not used for the music box performance itself, and the music box is played by a mainspring drive built in a manual winding type music box. The music box is clear during the performance of the music box by preventing the motor sound and winding up the music box with an electric motor (electric motor that rotates at a low speed that is manually wound up by a geared motor with a reduction gear) while the music box is stopped. Only the sound is beautifully resonated, and a clutch device is provided between the rotating shaft of the electric motor and the winding shaft of the music box, and the electric motor is connected by connecting the rotating shaft of the electric motor and the winding shaft of the music box when the music box is wound. Rotation force of the music box is transmitted to the winding axis of the music box so that it can be wound and the music box is playing The clutch device and the electric motor are controlled by the controller so that the music box can be played by allowing the rewind rotation of the music box winding shaft by disconnecting the connection between the rotating shaft of the electric motor and the winding shaft of the music box. By controlling it, the music box can be wound and played automatically and continuously, and it can also be used as a clock or alarm clock, or as a time notification chime that can notify the exact specific time with the beautiful beautiful tone of the music box. The present invention relates to a revolutionary music box automatic winding performance apparatus that can be used.

Conventionally, many types of manual-winding-type music boxes have been put to practical use. When classified according to the sound quality, the number of valves for determining the musical scale of the music is, for example, 18 in order from the low sound quality. There are valve, 23 valve, 30 valve, 50 valve and 72 valve, etc., low price products are 18 valves and 23 valves, and middle and high price products are 30 valves, 50 valves, 72 valves Can be given.

And, regardless of the quality and price range of the music box, the power source of the manual-winding music box is, without exception, the mainspring, and the principle is that a hardened steel spring plate is wound in a spiral shape. Then, the spring plate is elastically deformed by bending, and the strain energy of the spring plate accompanying the elastic deformation is stored, and when the strain energy is released, the mechanical output is taken out as a rotational force from the main shaft of the mainspring. .
A drum in which a large number of pins are planted is fixed to the rotation axis of the music box, and when the drum rotates, the pins hit the valve of the scale determined by the position and order determined by the music and flip it. Thus, the music is played by a series of sounds of the same or different scales.

In this case, it is necessary to rotate the drum at a very low speed in order to make the performance speed of the music the same as the speed of a normal instrument or singing, and if the rotation speed of the drum is uneven, the progress of the music is uneven. It is necessary to make sure that the drum rotation speed does not become uneven, and that the energy of the mainspring must be consumed over a long time so that the song can be played slowly and several times. In order to satisfy these conditions, the impeller is rotated at a very high speed through a gearbox with a very large gear ratio using a spur gear train and a worm gear connected to a rotating shaft. Apply the brakes by using the air resistance of this high-speed rotating impeller to make the drum rotation speed extremely low and stabilize the rotation speed so that you can play with beautiful tone without uneven music You have me.

The music box body is housed in a resonance box for resonating and amplifying the sound to make it easier to hear. From the resonance box, the music box winding shaft and the T-shaped winding arm are projected to the outside. The music box can be manually wound up from the outside of the resonance box, and the lid of the resonance box is openable. When the lid is closed while the music box is playing, part of the lid rotates at high speed. By stopping the rotation of the impeller by interfering with the wings of the impeller, the drum is stopped and the performance is stopped. When the lid is opened, the impeller is allowed to rotate and the drum is rotated. It is configured to play.
In addition, the force required to rotate the music box's winding shaft is such that it can be generated by the normal human thumb and index finger. It is. The winding speed is about 1 rotation per second, that is, about 60 rpm, and the necessary number of windings is set to about 4 times.

As described above, the manual winding type music box has a considerably large torque for rotating the winding shaft and needs to be wound at a low speed of about one rotation per second. Therefore, a technique for automatically winding it is provided. Therefore, there is no technology that can automatically play a manually-winding music box, and it has been the conventional technology that a music box is manually wound up.
For this reason, in the prior art, the sound of a music box with a beautiful beautiful tone is played, and a chime or the like using a music box that informs the time by sequentially playing different songs at a plurality of predetermined times cannot be provided at all. In addition, music box type alarm clocks, etc. that play a song suitable for it at bedtime and give a gentle tone, and play a cheerful song suitable for it when waking up to give a bright tone, etc. are realized at all. There was a drawback that it was not possible.

That is, when the manual winding type music box is wound by, for example, an electric motor, if the electric motor is a geared motor with a built-in speed reducer, the necessary torque can be easily obtained and the winding itself can be performed. However, if the rotating shaft of the electric motor and the winding shaft of the music box are fixed, when the winding is completed and the music box starts to play, the winding shaft rotates in the reverse direction in the reverse direction of the winding. While the mainspring is released, the electric motor has a built-in reduction gear with a very large reduction ratio (about 1/250). Because it is necessary to rotate at a high speed of about 13,400 rpm, a very large torque is required, and the electric motor itself acts as a generator to resist. As a result of the need for rewinding torque as a very large resistance, the rotating shaft of the electric motor is practically fixed, and the winding shaft of the music box cannot rewind and rotate. The fact was that performance was impossible at all.

Conventionally, a manual winding type, that is, a music box that is played by an electric motor from the beginning without using a mainspring has been put into practical use. However, according to this type of electric music box, the electric motor is always played during the performance of the music box. Therefore, the sound of this electric motor is amplified by the resonance box and mixed with the original beautiful tone of the music box. There was a drawback that it was heard as noise and the beautiful tone of the music box was impaired.

The applicant and the inventor of the present application have extracted the following patent documents as a result of the prior application search.

The connection between the rotary shaft 2a of the electric motor 2 and the winding shaft 3a of the music box 3 is cut off by releasing the contact and moving the nut and the rotary slide clutch member 30 in the direction of the electric motor 2. The music box 3 can be played by allowing the winding shaft 3a to rotate in the rewind direction in a stopped state.

8 to 11, the music box 3 is attached to a mounting plate 31 whose base 3d is fixed to the resonance box 8 by means such as screwing, and the round hole 31a of the mounting plate 31 is connected to its winding shaft 3a. Is penetrated with a considerable gap, and at the tip of the winding shaft 3a, an arm portion 3c for winding it up with a human finger is normally planted at right angles so as to form a T shape together with the winding shaft 3a. Two of the four engaging members 29 that are fixed and screwed to the rotary slide clutch member 30 are engaged with the arm portion 3c, and the rotary slide clutch member 30 rotates in the winding direction. Thus, the winding shaft 3a of the music box 3 is rotated in the winding direction so that the music box 3 is wound up.
The winding shaft 3a is different from a commercially available winding shaft (not shown) of the music box 3, and is replaced with a winding shaft 3a having a slightly longer length as shown in the figure, which is suitable for automatic winding.

Further, as shown in FIG. 11, the music box 3 is provided with a music head detection sensor 10 (a CMOS magnetic sensor is used as an example) for detecting the music music music head, on the base 3d. In order to make this detection possible, referring also to FIG. 16, a magnet 3f such as a neodymium magnet having a diameter of 10.5 mm is embedded and fixed at the beginning of the music of the drum 3e of the music box 3, and the music box 3 has its drum 3e. Since the music ends in one rotation of the music and returns to the head of the music, when the drum 3e is rotated by the performance of the music box 3 and the magnet 3f reaches the position facing the music head detection sensor 10, It is detected that this position is the beginning of the music, and this detection signal is input to the central information processing apparatus 5 (FIG. 26) via the input port I / P.

The electric motor 2 is a direct current motor and normally rotates at a very high speed. As an example, the appropriate load rotational speed is about 13,400 rpm, and therefore the speed at which the winding shaft 3a of the music box 3 is wound up by a human finger ( It will not be practical unless it is set to the same level as 60 rpm.
For this reason, since the electric motor 2 used in the present invention employs a geared motor incorporating a reduction gear 32 employing a spur gear train having a reduction ratio of 1/250, an appropriate load on the rotating shaft 2a of the electric motor 2 is adopted. The rotational speed at the time is set to a rotational speed of about 60 rpm, that is, about one rotational speed per second, and the winding shaft 3a of the music box 3 is rotated clockwise when viewed from the electric motor 2 at a speed similar to that of winding with a human finger. It can be wound up slowly and with a large torque.
Here, in the present invention (Claim 10), the meaning and the reason for limiting the number of rotations of the electric motor 2 to 60 rpm will be explained. The numerical value of 60 rpm is not strictly a numerical value of “60 rpm” but 60 rpm. The range of 60 ± 10 rpm should be interpreted as being included in “60 rpm” in the claims and the specification. It is. The reason for this is that if it exceeds 70 rpm, the winding speed will be slightly too high and the mainspring 3b of the music box 3 will be overwhelmed, and if it is less than 50 rpm, the winding time of the music box 3 will become longer and the winding will be more than necessary. This is because it takes time and the product value of the music box automatic winding performance apparatus 1 becomes inferior.
Note that the winding shaft 3a of the music box 3 is usually manufactured so that the right-handed user often winds up with the finger of the right hand, so that the clockwise direction is the winding direction toward the music box 3. Therefore, the electric motor 2 is also wired so as to rotate in the clockwise direction when viewed from the electric motor.

A circular mounting plate 33 is fixed to the electric motor 2 by means such as screwing, and three support columns 34 having female screw holes 34a at both ends are formed in mounting holes 33a formed in the mounting plate. As shown in FIG. 8, the electric motor 2, the mounting plate 33, and the three columns 34 are integrated by screwing and fixing with the screws 35, and the column 34 is fixed to the mounting plate 31 with screws. Moreover, the electric motor 2 is fixed to the resonance box 8.
In this case, the rotating shaft 2a of the electric motor 2 and the winding shaft 3a of the music box 3 are arranged in a straight line, and a clutch device 4 is interposed between them, and the rotating shaft 2a of the electric motor 2 is arranged as necessary. The winding shaft 3a of the music box 3 is connected and disconnected.

A joint 36 is fixed to the rotary shaft 2 a of the electric motor 2 by a set screw 38. One end 25 b of a screw shaft 25 having a diameter of 6 mm is fitted to the joint 36 by way of example, and a set screw 39. The screw shaft is formed with a flange portion 25d having a diameter larger than that of the screw shaft at the other end 25c, and the protrusion portion 25a has a larger diameter than the screw shaft 25 by approaching the flange portion. It is formed in a T shape.
The most important thing here is that the winding shaft 3a of the music box 3 is rotated clockwise in the clockwise direction when viewed from the electric motor 2, that is, the right direction is wound up. Instead of cutting the thread (not shown), the thread 25e of the left-hand thread is cut.
In addition, the lead of the screw thread 25e of the screw shaft 25 (the screw shaft 25 is a single thread and the pitch is equal to the lead) is set to 1 mm as an example, and the number of full windings of the winding shaft 3a of the music box 3 is about Since it is determined four times, the nut 26 and the rotating slide clutch member 30 are set to move in the axial direction by 4 mm by four rotations of the screw shaft 25.

In FIG. 8, a 6 mm left-hand nut 26 is screwed and arranged at a position 4 mm away from the protrusion 25a of the screw shaft 25 as an example, and the nut is a rotary slide clutch member. It fits in the space 28 of 30 round holes, and is fixed and integrated inside the rotary slide clutch member 30 by a pair of set screws 40.
When the screw shaft 25 rotates four times in the clockwise direction, that is, in the winding direction, the nut 26 moves to the left in the figure without rotating by 4 mm together with the rotary slide clutch member 30 and comes into contact with the protrusion 25a of the screw shaft 25. As a result, the nut 26 is integrated with the screw shaft 25, so that the clutch device 4 is connected, the rotary slide clutch member 30 stops moving and rotates clockwise with the screw shaft 25, and the music box is rotated by the engaging member 29. The mainspring 3b of the music box 3 can be wound up by rotating the 3 winding shafts 3a in the winding direction.

8 and 9, the four engaging members 29 have their screw portions 29 a screwed into the female screw holes 30 a of the rotary slide clutch member 30, and the screw portions 29 a of the engaging members 29 are fixed. The length of the round bar portion 29b is set to 6 mm as an example. Even when the rotary slide clutch member 30 slides to 4 mm in the direction of the electric motor 2, the engagement with the arm portion 3c of the winding shaft 3a of the music box 3 is never performed. The dimensions are set so that they do not come off.

In FIG. 9, a magnet 41 such as a neodymium magnet having a diameter of 10.5 mm is embedded in the outer periphery of the joint 36 as an example, and the rotational speed of the rotary shaft 2a of the electric motor 2 is set at a position facing the magnet. A rotation speed detection sensor 9 (a CMOS magnetic sensor is used as an example) is attached, and the right and left rotation speeds of the magnet 41, that is, the clockwise rotation speed and the counterclockwise rotation speed can be determined and detected. The detection result of the rotational speed in each rotational direction is input to the central information processing device 5 (FIG. 26) via the input port I / P, and the rotational direction of the electric motor 2 and the rotational speed in each rotational direction are input. Are controlled by the control device 6.

Next, the performance stopping electric motor 11 of the music box 3 will be described with reference to FIGS. When the music box 3 is automatically stopped, the performance stopping electric motor 11 operates simultaneously with the drum 3e of the music box 3 having finished playing and the start of the music being detected by the music start detection sensor 10 shown in FIG. When the wing 42a of the impeller 42 rotating at high speed is stopped and the music box 3 is manually stopped, the impeller 42 is immediately stopped in the same manner by pressing the stop switch 21 shown in FIG. It is what I did.

In FIG. 17, the performance stopping electric motor 11 is fixed to the base 3 d of the music box 3 with screws 45 via a mounting plate 43 and a column 44, and the rotation shaft 11 a is the base 3 d of the music box 3. The rotating shaft 46a of the swing stopper 46, which is disposed on the upper side of the impeller 42 and interferes with the rotational movement path of the blade 42a of the impeller 42 to stop the rotation, is quite strong so as not to slip in the rotational direction by the flexible silicon tube 48. The arm 46b of the swing stopper 46 is considered to be relaxed so that the impact when the arm 46b of the swing stopper 46 collides with the wing 42a of the impeller 42 is not damaged. ing.

The performance stopping electric motor 11 employs a geared motor with a built-in speed reducer 11b with a reduction ratio of 1/250 consisting of a spur gear train because the rotating shaft 11a needs to rotate at a low speed of about 60 rpm. Since the DC motor usually has an appropriate load rotational speed of about 13,400 rpm, if the reduction ratio is 1/250, the rotational speed of the rotary shaft 11a at the appropriate load is about 60 rpm, which is the target rotational speed. Yes.
Here, in the present invention (Claim 11), the meaning and reason for limiting the number of rotations of the electric motor 11 for stopping performance to 60 rpm will be explained. The numerical value of 60 rpm is strictly a numerical value of “60 rpm”. It means that it may be about 60 rpm, and it means that the normal music box (not shown) is manually stopped, that is, the opening and closing speed when opening and closing the resonance box etc. with the normal music box. Therefore, the range of 60 ± 10 rpm should be interpreted as being included in “60 rpm” in the claims and the specification.
The reason is that if it exceeds 70 rpm, the rotational speed of the stopper 46 is a little too fast and the impact on the wing 42 of the impeller 42 of the music box 3 becomes large, and the wing becomes unreasonable, and if it is less than 50 rpm, It is inconvenient that the time until the impeller 42 is stopped by the stopper 46 after the performance stopping electric motor 11 starts rotating is inconvenient, and the beginning of the music on the drum 3e of the music box 3 is detected by the music start detecting sensor 10. This is because the condition of stopping within 100 ms, for example, cannot be satisfied as soon as possible, and the drum 3e may rotate slightly more than the beginning of the song and overrun.
Since the proper swing angle of the stopper 46 is sufficient to be 30 degrees, the required operation time of the performance stopping electric motor 11 for securing the swing amount of 30 degrees may be set to about 100 ms. 3 is stopped, the performance stopping electric motor 11 is operated for about 100 ms to rotate the rotating shaft 11a counterclockwise, and the arm 46b of the stopper 46 is swung 30 degrees in the same direction in FIG. Thus, the music box 3 is kept in a performance stop state, and when the music box 3 is started to be played, the performance stop electric motor 11 is operated for about 100 ms from the state of FIG. If the rotary shaft 11a is rotated clockwise and the arm 46b of the stopper 46 is swung 30 degrees in the same direction and the power is turned off, the music box 3 is maintained in the playing state. It has been made.
Further, in order to surely stop the arm 46b of the stopper 46 at the same position without overrunning, a stop member 47 is fixed to the base 3d of the music box 3 by means such as screwing. When the stopper 46 swings counterclockwise in FIGS. 16, 18, and 19, that is, when the music box 3 is stopped, the stopper 46 reliably stops at the same position. Is configured to do.
Further, the stop member 47 is slightly affected by the torque from the drum 3e via the gearbox 49 as long as the strain energy of the mainspring 3b remains even when the music box 3 is stopped. Therefore, the wing 42a of the impeller 42 always presses the arm 46b of the stopper 46 in the direction of arrow F (counterclockwise) in FIG. It is also for preventing the arm 46b of the stopper 46 from swinging in the direction of arrow F.

In FIG. 16, a speed increasing device 49 is provided on the drum 3e of the music box 3, and a large-diameter spur gear 50 is coaxial with the drum 3e, and a flat gear is provided on the intermediate shaft 51. A small-diameter spur gear 52 meshed with the gear 50 and a medium-diameter spur gear 53 coaxial therewith are attached to the final shaft 54, and a small-diameter spur gear 55 meshed with the spur gear 53 and a worm wheel 56 coaxial therewith are attached. The worm wheel 56 meshes with the worm 58 fixed to the rotating shaft 42a of the impeller 42 to form a gear train of the speed increaser 49, and the extremely low speed rotation of the drum 3e is increased. The impeller 42 rotates at a very high speed together with the worm 58 in the direction of arrow A, and the air resistance of the wing 42a brakes the rotation of the drum 3e to enable the drum 3e to rotate for a long time. Rotation unevenness To have been configured to allow play of the stable song.

Next, another embodiment of the mechanical clutch device 4 will be described with reference to FIGS. In this embodiment, the four engagement members 29 of the rotary slide clutch member 30 of the clutch device 4 of the embodiment shown in FIG. 8 and the like are eliminated, and the center of rotation passes through the left end of the rotary slide clutch member 30 in the drawing. A notch groove 30b is provided, and the width of the notch groove is slightly wider than the diameter of the arm portion 3c of the winding shaft 3a of the music box 3, so that the arm portion engages with the notch groove 30b with some clearance. The arm portion 3c of the winding shaft 3a and the rotary slide clutch member 30 are constrained in the rotation direction and slidable in the axial direction. The rotary shaft 2a and the screw shaft 3a of the electric motor 2 are slid to each other while transmitting rotational force to the screw shaft 3a of the music box 3, and the winding of the music box 3 by the electric motor 2 and the electric motor 2 are performed. It is obtained by allowing the performance of the music box 3 by allowing unwinding rotation of the screw shaft 3a of the music box 3 during stopping.
Since other configurations are the same as those of the embodiment of FIG. 8 and the like, the same portions are denoted by the same reference numerals, and description thereof is omitted.

Next, a second embodiment of the clutch device 4 shown in FIGS. 22 to 25 will be described. In the second embodiment, an electric motor 2 for allowing rewinding rotation of the winding shaft 3a during the performance of the music box 3 using an electromagnetic clutch 59 instead of the mechanical clutch device 4 of the first embodiment. Thus, the counterclockwise rotation operation and its control are not required, and the mechanism is simplified and the control is facilitated.
The electromagnetic clutch 59 is connected to an electric motor 2, a manual winding type music box 3, and an electromagnetic coil (not shown) that is connected to the power source 60 in parallel with the electric motor 2 and energized to the electric motor 2. An electromagnet 61 that is energized to generate electromagnetic force and is rotatable by the action of a slip ring (not shown), and a shaft that is integrated with the electromagnet by being attracted to the electromagnet when the electric motor 2 rotates. The magnetic member 62 is slidable in the direction and constrained in the rotational direction, and either the electromagnet 61 or the magnetic member 62 is attached to either the rotating shaft 2a of the electric motor 2 or the winding shaft 3a of the music box 3 respectively. When the music box 3 is wound by the electric motor 2, the electromagnet 61 is energized by closing the music selection switch 20 or automatically controlled by the control device 6. And the magnetic member 62 are attracted and integrated to connect the rotating shaft 2a of the electric motor 2 and the winding shaft 3a of the music box 3, and the winding shaft 3a of the music box 3 is rotated in the winding direction to wind up the music box. When the music box 3 is played, the electric motor 2 is stopped and at the same time the energization of the electromagnet 61 is stopped to release the adsorption between the electromagnet 61 and the magnetic member 62, thereby rotating the rotating shaft 2a of the electric motor 2. The music box 3 can be played by allowing the winding shaft 3a to rotate in the rewinding direction while the electric motor 2 is stopped by disconnecting the connection between the music box 3 and the winding shaft 3a.

The casing 59a of the electromagnetic clutch 59 is kept stationary at all times by engaging the mounting arm 59b with a rotation stop 33b fixed to the mounting plate 33 of the electric motor 2 so that the casing 59a does not rotate with the rotating shaft 2a of the electric motor 2. The built-in electromagnetic coil (not shown) is fixed to the rotating shaft 2a of the electric motor 2, and the electromagnetic coil itself rotates together with the rotating shaft 2a.
In other words, a pair of brushes (not shown) connected to the wiring 63 connected to the external power supply 60 slide in an insulated state to transmit electricity to the electromagnetic coil, and the electric motor is built in the housing 59a. There is a slip ring (not shown) fixed to a rotary shaft (not shown) integral with the two rotary shafts 2a, and an electromagnetic coil is fixed to the slip ring, and the electromagnetic coil and an electromagnet 61 integral therewith are provided. It is configured to be rotatable.

In the clutch device 4 of the second embodiment, the electromagnetic clutch 59 causes the rotation shaft 2a of the electric motor 2 and the winding shaft 3a of the music box 3 to be completely disconnected from each other during the performance of the music box 3. Therefore, it is meaningless to detect the rotational speed of the rotating shaft 2a of the electric motor 2, and it is necessary to detect the rotational speed of the winding shaft 3a of the music box 3 and to input the detection result to the control device 6.
For this reason, a magnet 41 such as a neodymium magnet is embedded and fixed on the winding shaft 3a of the music box 3, and a rotational speed detection sensor 9 (a CMOS magnetic sensor is used as an example) is attached at a position facing the magnet 41. , The number of rotations in the clockwise direction when viewed from the electric motor 2 of the winding shaft 3a itself of the music box 3 (for example, four rotations in the clockwise direction when the music box 3 is wound) and the number of rotations in the counterclockwise direction (for example, the music box is fully played (Sometimes four rotations counterclockwise) is detected, and the detection result is input to the central information processing device 5 via the input port I / P.

Next, the control device 6 of the music box automatic winding performance device 1 shown in FIG. 26 will be described. The control device 6 includes a central information processing device 5, its input port I / P and output port O / P, and a storage device 64 including a random access memory RAM and a read-only memory ROM. The central information processing device 5 processes these input signals, and the control device 6 controls the outputs of the various output devices 66.
The input device 65 includes a setting switch 22, a music selection switch 20, a stop switch 21, a rotation speed detection sensor 9, a music title detection sensor 10, and a radio clock device 13, and an output device 66 includes four electric motors 2 (2A, 2B). , 2C, 2D), four clutch devices 4 (4A, 4B, 4C, 4D), four music boxes 3 (3A, 3B, 3C, 3D), four electric motors 11 for stopping performance (11A, 11B, 11C, 11D) and four illumination devices 12 (12A, 12B, 12C, 12D), and an input signal from the input device 65 is processed by the central information processing device (CPU) 5, and all of these output devices 66 are processed. Alternatively, a part is controlled by the control device 6 simultaneously or sequentially.
The read-only memory ROM of the storage device 64 stores various types of data, such as calendar, year, Japanese era, date, date, day, time, holiday name, music box Song name, performance time of each song, workplace, company, government office, school, nursery school, nursing home, home name, music box number, electric motor 2 number, performance stop electric motor 11 number, clutch device 4 number Etc. are stored and can be always read out by the central information processing device as necessary.
In the random access memory RAM, each numerical value input from the input device 65, for example, the performance status of each music box 3, the clockwise and counterclockwise rotation speeds of each electric motor 2 input from the rotation speed detection sensor 9 is stored. Difference argument value, time value of the radio time signal device 13, operation status of the performance stopping electric motor 11, stop position information of each music box from the music title detection sensor 10, usage status of the music selection switch 22, usage status of the setting switch 20, etc. Is digitized and stored, and can be always read out by the central information processing device as necessary.

Next, the control device 6 of the music box automatic winding performance device 1 that also serves as an alarm clock shown in FIG. 27 will be described.
The central information processing device 5 includes an input port I / P and an output port O / P thereof, a storage device 64 including a random access memory RAM and a read-only memory ROM, and various input signals from the input device 65. 26, the central information processing device 5 processes these input signals, and the control device 6 controls the outputs of the various output devices 66 and the contents of the input device 65 are the same as those of the control device 6 shown in FIG. is there.
The output device 66 includes two electric motors (2A, 2B), two clutch devices 4 (4A, 4B), two music boxes 3 (3A, 3B), two electric motors 11 (11A, 11B) for stopping performance, and It consists of one lighting device 12, and an input signal from the input device 65 is processed by the central information processing device 5, and all or part of these output devices 66 are controlled by the control device 6 simultaneously or sequentially. It is configured as follows.
The contents of the random access memory RAM and the read-only memory ROM are the same as those shown in FIG.

５ｍｍ位となっている。
そしてこのままでは、クラッチ装置４は電動モータ２の回転軸２ａとオルゴール３の巻上げ軸３ａとの接続を遮断しているため、電動モータ２を矢印Ｂの如く右回転、即ち巻上げ方向回転させても回転スライドクラッチ部材３０は全く回転せず、オルゴール３の巻上げ軸３ａを巻き上げることはできない。
そこで、電動モータ２を時計方向に矢印Ｂの如く更に右回転させると、ねじ軸２５が同方向に回転し、該ねじ軸が左ねじであり、そのリードが１ｍｍであるためねじ軸２５の１回転につき１ｍｍずつナット２６は矢印Ｃの如く無回転でオルゴール３方向にスライドし、ねじ軸２５の突起部２５ａに次第に接近して行き、当接するまでこのクラッチ装置４の「断」状態が続く。The present invention is configured as described above, and the operation thereof will be described below.
First, the operation of the mechanical clutch device 4 of the music box automatic winding performance apparatus 1 will be described with reference to FIGS. 8 to 15. In FIG. 12, when the assembly of the music box automatic winding performance apparatus 1 is completed, it is rotated in this way. The slide clutch member 30 is located closest to the electric motor 2, and the nut 26 is located farthest from the protrusion 25a of the screw shaft 25.

It is about 5mm.
In this state, since the clutch device 4 is disconnected from the rotating shaft 2a of the electric motor 2 and the winding shaft 3a of the music box 3, even if the electric motor 2 is rotated clockwise as indicated by the arrow B, that is, in the winding direction. The rotary slide clutch member 30 does not rotate at all, and the winding shaft 3a of the music box 3 cannot be wound up.
Therefore, when the electric motor 2 is further rotated clockwise as indicated by an arrow B, the screw shaft 25 rotates in the same direction, the screw shaft is a left-hand screw, and the lead is 1 mm. The nut 26 slides in the direction of the music box 3 without rotation as indicated by an arrow C in increments of 1 mm per rotation, gradually approaches the protrusion 25a of the screw shaft 25, and the clutch device 4 continues to be in the “disengaged” state until contact.

そしてこの状態でねじ軸２５が更に右回転しようとすると、もはやナット２６はねじ軸２５に対して相対移動は不可能であり、ねじ軸２５の突起部２５ａに強く押圧され、これによってねじ軸２５とナット２６及び回転スライドクラッチ部材３０が一体化されることで、クラッチ装置４は、電動モータ２の回転軸２ａとオルゴール３の巻上げ軸３ａとを接続することとなり、クラッチ装置４は「接」状態となる。
そこで更に電動モータ２が右方向に回転すると、回転スライドクラッチ部材３０が同方向に回転して、係合部材２９が巻上げ軸３の腕部３ｃを巻上げ方向に回転させ、オルゴール３が巻き上げられることになる。そしてクラッチ装置４が「接」状態になってから電動モータ２が４回転するとオルゴール３は巻上げ完了となり、これまでに電動モータ２は総計８回転しており、最初の４回転に加えて、巻上げの４回転の、巻上げ方向の合計８回転が回転数検出センサ９により検出されて、この検出結果が図２６に示す如く入力ポートＩ／Ｐを介して中央情報処理装置５に入力され、制御装置６により制御されて電動モータ２が回転を停止し、オルゴール３の巻上げが完了する。Next, as shown in FIG. 13, when the electric motor 2 starts to rotate and rotates four times to the right as indicated by the arrow B, the nut 26 slides 4 mm in the direction of the music box 3, and moves to the protrusion 25 a of the screw shaft 25. Abut. At this time, the side surface 30b of the rotary slide clutch member 30 and the

If the screw shaft 25 further rotates to the right in this state, the nut 26 can no longer be moved relative to the screw shaft 25 and is strongly pressed against the protrusion 25a of the screw shaft 25. And the nut 26 and the rotary slide clutch member 30 are integrated, the clutch device 4 connects the rotary shaft 2a of the electric motor 2 and the winding shaft 3a of the music box 3, and the clutch device 4 is "contact". It becomes a state.
Therefore, when the electric motor 2 further rotates in the right direction, the rotary slide clutch member 30 rotates in the same direction, the engaging member 29 rotates the arm portion 3c of the winding shaft 3 in the winding direction, and the music box 3 is wound up. become. Then, when the electric motor 2 rotates four times after the clutch device 4 is in the “contact” state, the music box 3 is completely wound up, and the electric motor 2 has been rotated a total of eight times so far in addition to the first four rotations. A total of 8 rotations in the winding direction are detected by the rotation speed detection sensor 9, and the detection result is input to the central information processing device 5 via the input port I / P as shown in FIG. 6, the electric motor 2 stops rotating, and the winding of the music box 3 is completed.

In this state, if an attempt is made to start playing the music box 3, the electric motor 2 is stopped, the clutch device 4 is in a "contact" state, and the winding shaft 3a is indispensable for the music box 3 to perform. As a result, the nut 26 and the screw shaft 25 are left-handed. As a result, the nut 26 is strongly pressed against the protrusion 25a of the screw shaft 25 in an attempt to move further in the direction of the music box 3. Moreover, since the electric motor 2 is a geared motor, the speed reducer acts as a speed increaser, and the electric motor 2 itself resists as a generator, so that the electric motor 2 has a very large braking action. As a result, it is impossible to rotate and music box 3 cannot be played.

そしてこの電動モータ２の反時計方向の４回転の終了が回転数検出センサ９により検出されて、この検出結果が入力ポートＩ／Ｐを介して中央情報処理装置５に入力され、制御装置６は電動モータ２を停止させる。
これによって、クラッチ装置４は「断」状態となり、オルゴール３の巻上げ軸３ａの巻戻し回転が許容される状態となり、制御装置６によるオルゴール３の演奏開始の指令が出るまでこの状態が維持される。Therefore, as shown in FIG. 14, the control device 6 obtains a signal indicating the rotation speed detection result of the completion of the winding of the music box 3 from the rotation speed detection sensor 9 and puts the clutch device 4 in the “disconnected” state. The motor 2 is instructed to rotate four times in the rewinding rotation direction, that is, counterclockwise, and the electric motor 2 starts to rotate counterclockwise as indicated by an arrow D.
Then, the nut 26 starts non-rotating sliding in the direction of the electric motor 2 as indicated by an arrow E, is detached from the protrusion 3c of the screw shaft 25, and the rotating slide clutch member 30 slides in the same manner, so that the electric motor 2 is counteracted. Nut 26 and rotating slide clutch after four clockwise rotations

Then, the end of four counterclockwise rotations of the electric motor 2 is detected by the rotation speed detection sensor 9, and this detection result is input to the central information processing device 5 via the input port I / P. The electric motor 2 is stopped.
As a result, the clutch device 4 enters a “disengaged” state, and a state in which the rewinding rotation of the winding shaft 3a of the music box 3 is allowed, and this state is maintained until the controller 6 issues a command to start playing the music box 3. .

As shown in FIG. 15, an instruction to start playing the music box 3 from the control device 6, that is, the performance stopping electric motor 11 shown in FIG. 17 is rotated clockwise in FIG. By retreating from the wing 42a, the rotation of the impeller 42 is allowed, the music box 3 can be played, and the performance is started.
When the performance of the music box 3 is started, the winding shaft 3a rotates in the counterclockwise direction as indicated by the arrow D. At this time, the clutch device 4 is in the “disengaged” state, so that the rewinding rotation is allowed. As a result, the arm portion 3c of the winding shaft 3a rotates the rotary slide clutch member 30 counterclockwise as indicated by the arrow D via the engagement member 3c of the rotary slide clutch member 30.
When the music box 3 starts to play, the nut 26 is separated from the protrusion 25a of the screw shaft 25 in the direction of the 4 mm electric motor 2, so that the nut 26 can slide within a range of 4 mm toward the protrusion 25a. In this range, the music box 3 can continue playing, and the rotary slide clutch member 30 moves in the music box direction as indicated by the arrow C while slowly rotating counterclockwise as indicated by the arrow D.
Then, the music box 3 plays the same music four times, for example, and the magnet 3f of the drum 3e reaches a position facing the music head detection sensor 10, so that the music end detection sensor 10 detects that the music box 3 has finished playing. When this signal is input to the central information processing device 5 via the input port I / P, the control device 6 rotates the performance stopping electric motor 11 counterclockwise by 30 degrees for 100 ms in FIG. The impeller 42a is stopped by the arm 46b of the stopper 46, and the music box 3 stops playing. Note that the arm 46b of the stopper 46 comes into contact with the stop member 47 of the base 3d and stops, thereby preventing excessive rotation.

At this time, the clutch device 4 is already in the “contact” state, that is, the state in which the music box 3 shown in FIG. 13 can be wound up, because the nut 26 is already in contact with the protruding portion 25a of the screw shaft 25. As soon as the control device 6 issues a command to start winding to the electric motor 2, the electric motor 2, the screw shaft 25, the nut 26, the rotary slide clutch member 30, the engaging member 29, the arm portion 3c, and the winding shaft 3a are moved to the arrow B. Thus, the music box 3 is wound up by rotating in the winding direction, that is, in the clockwise direction.
Then, the music box 3 is automatically wound up any number of times by the above-described repetition, that is, the music box automatic winding performance device 1 by the connection and disconnection of the clutch device 4, and the automatic performance can be continued.

If the performance is stopped in the state that the mainspring 3b of the music box 3 is rewound about half by stopping the performance in the middle of the performance of the music box 3 as shown in FIG. 15, the performance can be started again as it is. You can, but then you will have about half the time you can play.
When such a state is disliked, the clutch device 4 is “contacted” by rotating the electric motor 2 clockwise in the state of FIG. 15 and rotating the nut 26 until it abuts against the protruding portion 25a of the screw shaft 25. Thus, by continuing the clockwise rotation of the electric motor 2, the mainspring 3b of the music box 3 can be wound up until it can be fully played.

Next, the operation of the clutch device 4 according to another embodiment of the mechanical clutch device shown in FIGS. 20 to 21 will be described.
When the rotary slide clutch member 30 rotates, the arm portion 3c of the winding shaft 3a of the music box 3 engaged with the engagement groove 30b rotates and the winding shaft 3a rotates in the same direction. The music box 3 is wound up by clockwise rotation, and the revolving rotation of the music box 3 causes the rotary slide clutch member 30 to slide in the direction of the music box 3 while rotating counterclockwise, and when the screw shaft 25 rotates counterclockwise. The nut 26 and the rotary slide clutch member 30 slide in the direction of the electric motor 2 without rotation. At this time, the arm portion 3c of the screw shaft 3a of the music box 3 slides relatively in the notch groove 30b, and the engagement is never performed. I can't come off.
With the above operation, in the clutch device 4 of this embodiment, the rotating shaft 2a of the electric motor 2 and the screw shaft 3a of the music box 3 can be smoothly connected and disconnected. The four engaging members 29 of the rotary slide clutch member 30 can be omitted, the assembling work thereof can be omitted, and the mechanical strength can be further increased.

Next, in FIG. 16 to FIG. 19, the operation of the performance stop electric motor 11 of the music box 3, the stopper 46 of the impeller 42 of the music box 3, and the music start detection sensor 10 will be described. The rotation direction of the performance stop electric motor 11 will be described as the rotation direction viewed from the performance stop electric motor.
There are two cases in which the performance of the music box 3 is stopped in the music box automatic winding performance device 1, and one is forced by pressing the stop switch 21 shown in FIG. The second is a case in which the program is automatically stopped at the beginning of the music by programmed automatic performance.
In any of these cases, in order to stop the performance of the music box 3, the power to the performance stop electric motor 11 must be turned on and the performance stop electric motor 11 must be rotated 30 degrees clockwise for, for example, 100 ms. The performance stop electric motor 11 is stopped by turning off the power, and the stopper 46 and the arm 46b are rotated 30 degrees in the same direction (counterclockwise in FIG. 16) via the rotating shaft 11a, the silicon tube 48 and the rotating shaft 46a. Then, the arm 46b is made to interfere with the operating path of the blade 42a of the impeller 42 rotating at high speed, and the impeller 42 is stopped. 16 and 19 show a state where the music box 3 is stopped.
In addition, in the case where the music box 3 is stopped in the case of the programmed automatic performance of the music box 3, the magnet 3f of the drum 3e is opposed to the music start detection sensor 10 in FIG. When the controller 6 turns on the power of the performance stop electric motor 11 instantaneously and rotates the performance stop electric motor clockwise by 30 degrees for 100 ms as described above, the power is turned off and stopped. The stopper 46 stops the impeller 42, and the drum 3e of the music box 3 stops at the beginning of the song.
When starting the performance of the music box 3, as shown in FIG. 18, the electric power of the performance stop electric motor 11 is turned on and the performance stop electric motor 11 is rotated counterclockwise by 30 degrees for 100 ms. The performance-stopping electric motor 11 is turned off and stopped. As a result, the stopper 46 rotates 30 degrees clockwise as shown in FIG. 18 as shown in FIG. 18 to open the impeller 42, and the impeller starts to rotate at high speed as shown by the arrow A. The music box 3 starts to play after rotating.
In this case, the music box 3 may start playing in the middle of the song, or may start playing at the beginning of the song. As described above, this is the difference between manual performance and automatic performance. The person can choose freely in either case.

Next, the operation of the clutch device 4 of the second embodiment shown in FIGS. 22 to 25, that is, the electromagnetic clutch 59 will be described. If the music selection switch 20 is not pressed and the energization of the electric motor 2 and the electromagnetic clutch 59 is stopped, the electric motor 2 is stopped and the electromagnetic clutch 59 is energized to the electromagnetic coil as shown in FIG. Therefore, the electromagnet 61 has no magnetic force, and the magnetic member 62 is in a free state, so that the clutch device 4 “disconnects” between the rotating shaft 2 a of the electric motor 2 and the winding shaft 3 a of the music box 3. Since the music box 3 is in a state, the rewinding rotation of the winding shaft 3a is allowed, so that the music box 3 is in a playable state.
However, as shown in FIG. 23, when the mainspring 3b of the music box 3 is completely rewound as a result of the full performance of the music box 3, the music box 3 is not played unless the winding by the electric motor 2 is performed.
Therefore, as shown in FIG. 24, when the music selection switch 20 is pushed and the electric motor 2 and the electromagnetic clutch 59 of the clutch device 4 are energized, the electric motor 2 starts to rotate clockwise as indicated by an arrow B. At the same time, since the electromagnet 59 has a magnetic force, the magnetic member is attracted as indicated by an arrow E, whereby the clutch device 4 brings the rotating shaft 2a of the electric motor 2 and the winding shaft 3 of the music box 3 into a "contact" state. The rotating shaft 2a and the winding shaft 3a rotate as a unit, the winding shaft 3a rotates in the winding direction as shown by the arrow B, and the mainspring 3b of the music box 3 is wound up.
The rotational speed of the winding shaft 3a is detected by the rotational speed detection sensor 9, and is input to the central information processing device 5 via the input port I / P of the control device 6 as shown in FIG. When the number of rotations reaches four, the control device 6 stops the electric motor 2 and the winding of the music box 3 is completed and stopped.
As a result, as shown in FIG. 25, the electric motor 2 and the electromagnetic clutch 59 of the clutch device 4 are again de-energized, so that the electromagnet 61 loses magnetic force and the clutch device 4 is connected to the rotating shaft 2a of the electric motor 2. The music box 3 is allowed to be unwound and rotated so that the music box 3 is in a “disconnected” state with the winding shaft 3a of the music box 3.
Accordingly, the control device 6 rotates the performance stopping electric motor 11 in the clockwise direction to release the restraint of the impeller 42 by the stopper 46, so that the music box 3 starts playing, and in the case of automatic performance, it performs a full performance. Music is performed until the magnet 3f of the drum 3e faces the song head detection sensor 10, the electric motor 11 for stopping performance is energized again, the impeller 42 is restrained by the stopper 46, and the impeller 42 is stopped. Stops playing.
In this way, the clutch device 4 can also connect and disconnect between the rotating shaft 2a of the electric motor 2 and the winding shaft 3a of the music box 3 by the electromagnetic clutch 59 in the same manner as the mechanical clutch device 4. 3 automatic winding and automatic performance are possible.

Next, the operation of the music box automatic winding performance device 1 shown in FIGS. 1 to 4 will be described together with the control by the control device 6 shown in FIG.
The music selection switch 20 of the music box automatic winding performance apparatus 1 is used when listening to a favorite song manually or automatically when desired according to the user's preference. In FIG. When the button is pressed, a signal enters the central information processing device 5 via the input port I / O from the music selection switch 20 of the input device 65 shown in FIG. 26, and the central information processing device 5 processes this signal to output the output port. An output signal is output from the O / P and the electric motor 2A is rotated four times in the clockwise direction to wind up the music box 3A. When the winding is completed, the electric motor 2A is rotated four times in the counterclockwise direction to move the rotary slide clutch member 30 in the direction of the electric motor 2 And the clutch device 4 makes a “disengaged” state between the rotating shaft 2a of the electric motor 2 and the winding shaft 3a of the music box 3A, and rewinds the music box 3A. By allowing rotation, music box 3A is the state of possible play.

At the same time, the performance stop electric motor 11 is energized by the control device 6 for 100 ms until the performance stop electric motor 11 rotates 30 degrees, and then the energization is stopped to stop the performance stop electric motor 11. The restraint of the impeller 42 of the music box 3A by the stopper 46 is released, and the performance of the music box 3A is started.

On the other hand, the central information processing device 5 outputs an output signal for turning on the lighting device 12 from the output port O / P, turns on the lighting device 12A that illuminates only the music box 3A, and the user is playing the music box 3A. As can be clearly seen, only the upper left round hole 8b in FIG. 1 is lit brightly to indicate that the music box 3A is playing.
Thus, unless the user presses the stop switch 21, the music box 3 continues to automatically play the same music of the same music box 3A by automatic winding, and the lighting device 12A keeps lighting.

In order to stop the performance of the music box 3A, the user only has to press the stop switch 21. When the stop switch 21 is pressed, the signal is input to the input port I / P of the control device 6, and this signal is Processed by the central information processing device 5 to output a necessary output signal from the output port O / P and energize the energizing motor 11A for 100 ms until its rotating shaft 11a rotates 30 degrees clockwise. And the impeller 42 of the music box 3A is stopped by the stopper 46 to stop the music box 3A. In this case, since the music box 3A is manually stopped, the music head detection sensor 10 does not work, and the drum 3e of the music box 3A stops at an arbitrary position.

Next, a case where the music box 3 is programmed to perform automatic winding performance will be described. For example, when the music box automatic winding performance device 1 is used as a chime in a workplace, nursery school, school, or the like, the setting switch 22 is used. The description related to the control device 6 is the same as described above, and will be omitted.
When the push button 24A or 24B of the setting switch 22 is pressed to select the item "daily", the push button 24E is pressed to determine the item "daily", and then the push button 24A or 24B is pressed to select the item "music box number". The push button 24E is pressed to determine the item “music box number”, and then the push button 24C or 24D is pressed to select the music box 3 number to be displayed on the liquid crystal display panel 23 as “3A”, and the push button 24E is pressed. The music box number “3A” is determined, then the push button 24A or 24B is pressed to select the item “performance time”, the push button 24E is pressed to determine the item “performance time”, and the push button 24C or 24D is pressed to select “ “9:00:00” is selected and displayed on the liquid crystal display panel 23, and the push button 2 E is pressed to determine the performance time “9:00:00”, and similarly, the music box 3B performance time is 12:00:00, music box 3C performance time 15:00:00, music box 3D If the performance time is determined at 17:00:00, the music box automatic performance device 1 is programmed with the music box 3A, the music box 3B at 12:00, the music box 3C at 15:00, the music box 3C at 15:00, and the music box 3D at 17:00. An automatic performance is performed, and the lighting device 12 of the music box 3 is turned on for each performance of the music box, so that the music box 3 being played can be visually recognized from the outside.

Next, the operation of the music box automatic winding performance apparatus 1 that also serves as an alarm clock shown in FIGS. 5 to 7 will be described.
When the music box 3 is to be programmed for automatic winding performance, for example, when the music box automatic winding performance apparatus 1 is used as an alarm clock in daily life, the push button 24A or 24B of the setting switch 22 is first pressed to select “music box”. The item “number” is selected and the push button 24E is pressed to determine the item “music box number”. Then, the push button 24C or 24D is pressed to display the number of the music box 3 on the liquid crystal display 23 and select “3A”. Then, the music box number “3A” is determined by the push button 24E, and then the push button 24A or 24B of the setting switch 22 is pushed to select the item “year / month / day”. And press the push button 24C or 24D to display the numeric date on the LCD panel 2 To select the target date, press the push button 24E to determine the date, and then press the push button 24A or 24B to select the item “sleeping time” and press the push button 24E to select the item “ Similarly, the user presses the push button 24C or 24D to display the bedtime value on the liquid crystal display panel 23 to select the target bedtime, and press the push button 24E to determine the bedtime. If the music box 3B for wake-up, date, and time of wake-up are determined in the same manner, the music box 3A for sleeping and the music box 3B for wake-up are automatically played in what year / month / day / hour / minute / second, respectively. At the time of going to bed, the lighting device 12 is turned on so as to be dark for a while and then turned off, and when waking up, the lighting device 12 is turned on so that it is bright for a while. It can be used as a clock.
