6 to 10 show a plate forming mechanism of the medal plate marking apparatus of FIG.
6 is a perspective view showing the entire plate forming mechanism, FIG. 7 is a perspective view from the back side of the upper position of the plate forming mechanism, FIGS. 8, 9 and 10 are right side views, plan views and AA cross sections. FIG.
The fixed base 66 is fixed to an apparatus housing (not shown), and roller mounting plates 68 and 69 for incorporating a roller portion for forming a plate are erected on the upper surface. A motor 61 for driving the plate attachment roller is attached to the lower surface. A gear 63 is fixed to the drive shaft 62 of the motor 61.
On the other hand, a shaft 70 is rotatably attached to the roller mounting plates 68 and 69, and a gear 71 is fixed to one end of the shaft 70. A chain 64 is stretched between the gears 63 and 65, and the rotational force of the motor 61 is transmitted to the shaft 70.

As shown in FIG. 7, a rolling roller 74 is fixed to the shaft 70, and a gear 71 is attached to the end of the shaft 70. A shaft 73 is rotatably mounted on the roller mounting plates 68 and 69 in parallel with the shaft 70, and three plates (a first plate 76a, a second plate 76b, and a third plate are spaced on the shaft 73 at an interval of approximately 120 degrees. A plate attachment roller 75 with a plate 76c) attached to the peripheral surface is fixed. Further, a gear 72 that meshes with the gear 71 is attached to the end thereof. The first plate 76a, the second plate 76b, and the third plate 76c are provided with irregularities with different patterns to be stamped.
The rotational force of the motor transmitted to the shaft 70 is transmitted to the gear 72 via the gear 71 and rotates the plate attachment roller 75. While the circumferential surface of the rolling roller 74 and the plate of the plate attachment roller 75 are brought into pressure contact, the rolling roller 74 and the plate attachment roller 75 rotate together.
A guide rail 77 for guiding the original medal plate 78 to the pressure contact surface is provided on the upper surfaces of the roller mounting plates 68 and 69 on the pressure contact surfaces of the rolling roller 74 and the plate mounting roller 75. The guide rail 77 has a structure in which a long groove is formed in the vertical direction, and the original medal plate 78 falls while being regulated by the side wall of the long groove. A transparent plate (not shown) is stuck on the long groove so that the original medal plate 78 does not jump out.

A through hole 77 a through which the solenoid plunger 84 enters and exits is formed near the upper portion of the guide rail 77. When the solenoid plunger 84 protrudes from the through hole 77a, the medal original plate 78 sent from a medal original plate hopper (not shown) stops in the guide rail 77, and when the plunger 84 is retracted by driving the solenoid, the medal original plate 78 is It falls on the pressure contact surface between the rolling roller 74 and the plate mounting roller 75.
A plate formation timing signal for dropping the medal original plate 78 is formed by the cam 80 shown in FIGS. A cam 80 is fixed to the shaft on the back side of the gear 65.
The cam 80 is provided with cam portions 80 a, 80 b, and 80 c at an interval of approximately 120 degrees on the circumferential surface thereof, and a mechanical switch 81 is disposed along the circumferential surface of the cam 80. A roller-shaped contact portion 82 protrudes from the tip of the mounting rod 83 of the mechanical switch 81. When the contact portion 82 is pushed up by the cam portions 80a, 80b, and 80c, the mounting rod 83 rotates to rotate the mechanical switch. 81 is activated to generate the plate forming timing signal described above.

The circumferential surface protruding portion 800a connected to the cam portion 80a is for making a signal for detecting the initial position.
Screw portions 800b and 800c are formed in the cam portions 80b and 80b, and screws are inserted into these portions to fix the cam 80 to the shaft 70. The circumferential surface mounting position of the cam 80 can be adjusted with respect to the shaft 70.
The medal original plate 78 is dropped by the plate formation timing signal thus produced, and is rolled and engraved with the plate selected by the user. Since the roller surface is a circumferential surface, the medal engraved with the pattern is curved, and the curved medal falls below the plate forming mechanism and is paid out of the apparatus.

In the medal plate forming mechanism having such a configuration, the cam 80 forms a pattern at the center position of the medal if the position of the cam portion and the position of each plate are always accurate.
However, individual plate shifts in manufacturing that occur during plate production, assembly shifts when mounting plates to machines, assembly shifts such as meshing of gears, and many rolling operations, The version may be shifted slightly. Therefore, it is necessary to adjust the position of the plate according to the unevenness of the cam portion.
Japanese Patent Laid-Open No. 2005-74854 Japanese Utility Model Publication No. 62-137626

The structure for detecting the plate position of the above-mentioned medal plate forming mechanism is that the cam is attached to the rotating shaft as described above, and the mechanical position is detected by operating the mechanical switch by using the unevenness of the cam. The unevenness of the plate is always constant, and when there is one plate, it is possible to correct the plate deviation by adjusting the cam. However, when several plates are attached to the rotating shaft, the plurality of plates can be adjusted simultaneously according to the shape (unevenness) of the cam. The plate attachment roller having a plurality of plates can have different plate attachment holes 760a due to individual differences of the plates. The position of the plate to be mounted on the plate is different, and it is often difficult to locate the appropriate plate. In addition, there are individual manufacturing plate shifts that occur during plate production, It was very difficult to properly position all the plates due to the effects of assembly displacement such as meshing of gears.
The plate forming mechanism is considered to be created and implemented by the applicant of the present application, and includes the problems described above.

There is no conventional prior art of this type that uses an optical pulse to adjust the plate position in a medal plate marking apparatus. From the viewpoint of a printing apparatus using an encoder, there is one that detects whether rotation has been performed using a rotary encoder to detect whether or not a pre-printed master has arrived on the outer peripheral surface of the plate cylinder (Patent Document 1). The relevance to the present invention is less than that of the above-mentioned technique by the applicant.
Also, there is Patent Document 2 that transfers as an apparatus for forming a concavo-convex pattern of a plate with a roller, but there is no disclosure of a technique for accurately detecting a plate position.
The object of the present invention is to detect the position information of the rotating shaft electrically by using a pulse system that detects a position by an optical sensor, not a cam system that detects a mechanical position, and a pulse that matches the position of each plate. It is to provide a plate position adjusting mechanism in a medal plate stamping device that can perform regular positioning (position where a plate can be formed in the center of a medal original plate) for each plate by setting numerical information. .

In order to achieve the above object, according to claim 1 of the present invention, the original medal plate is stopped at a predetermined position of the guide rail, and a rolling roller having a flat rotating surface and one or more plates are mounted on the rotating surface by the plate rotation driving means. The plate attachment roller is rotated together, and the stopped medal original plate is moved to the contact surface between the rolling roller and the plate attachment roller by a plate formation timing signal, and the medal original plate is placed between the rolling roller and the plate attachment roller. In a medal plate stamping device that forms a curved medal by transferring the uneven pattern of the plate to the original medal plate and then rolling out the medal plate marking device, a plurality of slits on the peripheral surface of the plate mounting roller shaft And a position detection optical sensor for detecting the slit, and a block for detecting the origin position on the circumferential surface of the disk having the plurality of slits. And an origin position detecting optical sensor for detecting the blade. When the origin position detecting optical sensor detects the blade by the rotation of the plate mounting roller, the position detecting optical sensor The number of pulses from when the blade is detected to the slit in the vicinity of the target plate position set in advance corresponding to the plate is measured, and preset from the plate position when the preset number of pulses is measured A plate forming timing signal generating means for outputting a plate forming timing signal when the time has elapsed; and a time adjusting means for adjusting the preset time by operating an operation knob. Adjusting and generating the plate formation timing signal in accordance with the plate position of the plate mounting roller, the center position of the dropped medal original plate Characterized in that to form the pattern of the plate in.
According to a second aspect of the present invention, in the first aspect of the present invention, the guide rail is provided with a guide in a substantially vertical direction, and is moved by being dropped by its own weight of the medal original plate. A solenoid for operating the plunger back and forth according to a formation timing signal is provided, and the end of the plunger is protruded in the middle of the guide rail to stop the dropping of the medal original plate, and the medal original plate is dropped by retracting. And
According to a third aspect of the present invention, in the invention of the second aspect, the one or more plates are three, and the plate formation timing signal generating means is configured to detect the blade when the origin position detecting optical sensor detects the blade. A pulse number counting means for counting the number of pulses from when the optical sensor for detecting the origin position detects the blade to the slit in the vicinity of the target position set in advance for each of the three plates, and for each plate Time counting means for measuring a preset time from the plate position when the pulse number counting means counts a preset number of pulses for each plate, and the solenoid for each plate It is characterized by operating correspondingly.
According to a fourth aspect of the present invention, in the invention according to the third aspect, the time adjusting means preliminarily corresponds to each plate corresponding to a plate position adjusting volume arranged in the apparatus corresponding to the plate and rotation of the knob of the volume. The time adjustment unit adjusts the set time back and forth, and a solenoid control unit that operates the solenoid after the time adjusted by the time adjustment unit.

According to the above configuration, there is no deviation between the plate position and the cam shape as in the cam system (mechanical position detection). In other words, individual plate positions against deviations due to individual manufacturing errors that occur during plate production, assembly deviations when mounting plates on a machine, and assembly deviations such as gear meshing. Adjustment is possible. Further, if the rolling operation is performed many times, the plate may be slightly shifted. However, if the position information of the pulse is adjusted at that time, it can be easily handled without adjusting the position of the cam by disassembly or the like.
Further, when the plate is displaced, the rolling position can be easily changed by correcting the position information of the plate in the same manner.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing an embodiment of a plate forming mechanism to which a plate position adjusting mechanism according to the present invention is applied. The parts denoted by the same reference numerals as the structure of each mechanism part described with reference to FIG. 7 perform the same function, and the background is that the disk 72 with a slit that functions as a rotary encoder is provided on the front surface of the gear 72. It is different from technology. Further, the cam 80 and the mechanical switch 81 shown in FIGS. 8 to 10 are not provided.
Each of the slits 2 of the disk 1 with slits is provided along the circumferential surface. In order to detect the slit 2, the position detecting optical sensor 3 is attached to a roller mounting plate 69 (not shown in FIGS. 1 and 7).
The position detecting optical sensor 3 includes a light emitting element part and a light receiving element part, and the light emitting element part and the light receiving element part are arranged so as to sandwich a slit group on the circumferential surface of the disk 1 with slits. The light receiving element unit detects light emission from the light emitting element unit to detect the slit, and the light receiving element unit outputs a signal indicating the detection of the slit.

  A blade 5 is fixed to the circumferential surface of the slit disc 1, and an origin position detecting optical sensor 4 for detecting the blade 5 is attached to a roller mounting plate 69. Similarly to the position detecting optical sensor 3, the origin position detecting optical sensor 4 includes a light emitting element portion and a light receiving element portion. When the gear 72 rotates and the blade 5 reaches between the light emitting element portion and the light receiving element portion, the light receiving element portion receives light. The element unit shields light from the light emitting element unit, detects the blade, that is, the origin position, and outputs an origin position detection signal. The initial stop position of the blade 5 is set so that the rotation of the motor becomes stable when the motor starts rotating and the blade 5 reaches the optical sensor 4 for detecting the origin position.

FIG. 2 is a block diagram showing a circuit configuration of a medal plate marking apparatus employing a plate position adjusting mechanism according to the present invention.
Each circuit unit is mounted on the control board 10, and a ROM 18, a RAM 19, and a nonvolatile memory unit 20 are connected to the CPU 14. Further, a motor drive unit 17 comprising a relay for driving on and off a plate rotation motor (plate rotation driving means) 61, a sensor control input / output circuit 16 for controlling the origin position detection sensor 4 and the position detection optical sensor 3, and a medal escrow. Solenoid control input / output circuits 15 for controlling the solenoid 11 are connected to each other. Further, an A / D converter 13 for A / D converting analog voltages from the three plate position adjusting volumes 12a, 12b and 12c is connected.

The ROM 18 stores a control program for driving the plate forming mechanism and various data used when the control program is driven.
The nonvolatile memory unit 20 stores set pulse number data n ₁ , n ₂ , n _{3 for the} three versions and set time data t ₁ , t ₂ , t ₃ for the three versions, respectively. This set time data can be changed back and forth around the time preset by the plate position adjusting volumes 12a, 12b and 12c. Each plate position adjusting volume 12a, 12b and 12c has set time data t ₁ , t ₂ and t ₃ for each plate in order to set individual manufacturing plate shifts at the time of assembling the apparatus to a normal position. Can be adjusted independently.
The RAM 19 is used as a work area when the CPU 14 performs calculations and the like, and further stores data temporarily.
The CPU 14 reads out and executes the control program from the ROM 18, thereby realizing the functional units of the plate forming control unit 14a, the pulse number counting unit 14b, the time measuring unit 14c, and the time adjustment calculating unit 14d.

The plate forming control unit 14a performs management and control of the entire apparatus. Control of the plate forming mechanism unit for coin insertion, arithmetic control for input from the plate position adjusting volume 12, origin position detecting optical sensor 4 and position detection. Input / output control of the optical sensor 3 and drive control for the medal escrow solenoid 11 and the plate rotation motor 61 are performed.
When the knobs of the plate position adjusting volumes 12a, 12b, and 12c are operated, the analog voltage changed by the operation is converted into a digital voltage by the A / D conversion unit 13. The time adjustment calculation unit 14d calculates the time variation in the digital voltage, and updates preset time data t ₁ , t ₂ , t ₃ stored in the nonvolatile memory unit 20.
The pulse number counting unit 14b counts the number of pulses generated in the slit detected from the origin position by the pulse position detecting optical sensor 3.
The time measuring unit 14c measures time from the time when the number of pulses counted by the pulse number counting unit 14b becomes n ₁ , n ₂ , n ₃ . When the time measured by the plate forming the control unit 14a is the time measuring unit 14c becomes _{t 1, t 2, t 3} , and sends the solenoid drive signal (plate forming timing signal) to the solenoid control output circuit 15.

FIG. 3 is a flowchart for explaining a process of forming a medal according to the present invention. Hereinafter, the details of the flow of plate formation will be described with reference to FIGS. 1, 2, 5, and 6. The step part surrounded by the dotted line is the part of the flow directly related to the present invention.
When the medal purchaser inserts a coin of 100 yen into the coin insertion unit 55, the plate formation control unit 14a confirms that the determined coin has been inserted (step (hereinafter referred to as “S”) 001). As a result, the medal hopper for accumulating a large number of medal original plates is operated to pay out one medal original plate 78 to the entrance of the guide rail 77 (S002). The medal original plate 78 attempts to drop the guide rail 77, but since the plunger 84 of the medal escrow solenoid protrudes from the guide rail 77, the medal original plate 78 stops dropping downstream (S003).
On the other hand, the plate formation control unit 14a turns on the light emission lamps of the three plate selection buttons on the plate selection panel 54 on which different patterns can be selected, and prompts the medal purchaser to press the desired plate selection button.

When the plate is selected (S004), the plate formation control unit 14a sends a drive signal to the motor drive unit 17 by a signal sent from the plate selection button to rotate the motor 61 (S005).
The rotational force of the motor 61 is transmitted to the chain 64 via the shaft 62 and the gear 63, decelerated by the gear 65 and transmitted to the shaft 70. The rotation of the shaft 70 is transmitted to the shaft 73 via the gears 71 and 72, and the rolling roller 74 and the plate attachment roller 75 start rotating, and the slit disk 1 also starts rotating.
The initial position of the plate mounting roller 75 is a state in which the blade 5 is stopped at a position closer to the origin position detection optical sensor 4 by a predetermined angle. The rotation starts from this position, and the optical position detection optical sensor 4. , The origin position detection signal is output from the light receiving element portion of the position detection optical sensor 4.

Upon receiving the origin position detection signal, the plate formation control unit 14a resets the pulse number measurement unit (counter) 14b to 0, and the pulse number measurement unit starts counting the number of pulses detected by the position detection optical sensor 4. (S006).
Further, the plate rotates (S007). Plate forming control unit 14a is, for example, if it be the first plate 76a is selected, reads the setting pulse number data n ₁ from the non-volatile memory unit 20, the pulse counting unit 14b counts the set number of pulses data n ₁ or Is determined (S008). When the number of pulses counted the set pulse number data n _1, the following is to count the time from the time of counting the set pulse number data n ₁ to the time measuring unit 14c. Then, it is determined whether or not the set time data t ₁ has been counted (S009). When the set time data t ₁ is counted, the plate forming control unit 14 a outputs a plate forming timing signal d ₁ to the solenoid control input / output circuit 15, and the solenoid control input / output circuit 15 drives the medal escrow solenoid and the plunger 84. Pull in. Thereby, the original medal plate 78 falls in the guide rail 77 (S010).

In the above operation, if the second version 76b is selected, the set pulse number data n ₂ and the set time data t ₂ are used. If the third version 76c is selected, the set pulse number data n _{3 is used.} And set time data t ₃ are used.
The dropped original medal plate 78 is sandwiched between the plate end positions of the rolling roller 74 and the plate mounting roller 75, and the medal original plate 78 is rolled and a plate pattern is formed in the middle of the medal original plate 78 (S011).
The rolled medal falls to the lower part of the plate forming mechanism and is paid out to the medal paying part 58 through the passage (S012). After dropping the medal, the plate formation control unit 14a further rotates the plate attachment roller 75 to stop the motor at the initial position for starting the rotation (S013).

FIG. 4 is a timing chart for explaining the adjustment position of each plate.
The circumferential part of the disk 1 with slits is developed in the time axis direction, and pulses generated by the slits are described. For each plate, the origin detection position is the same position, but the number of pulses generated from the origin detection position is n ₁ , n ₂ , and n ₃ , respectively, and the time after counting the set number of pulses is t ₁ , t _2. , T ₃ . Therefore, for the first, second and third plates, the plate is determined by the time from the origin detection to (pulse number n ₁ + time t ₁ ), (pulse number n ₂ + time t ₂ ), and (pulse number n ₃ + time t ₃ ). A plate formation timing signal for dropping a medal is output at a distance (rotation angle) rotated by. This is because if the motor speed is always constant and other mechanical elements are the same as the original dimensions or the assembly does not vary, the plate is formed in the middle of the medal with the initially set time data in the medal rolling process using the plate. It will be.

However, in actuality, there are individual manufacturing deviations that occur during the production of the plate, assembling deviations such as when the plate is attached to the machine, and meshing of gears and the like. Also, when rolling the plate, the plate may be slightly shifted. Therefore, even if the appropriate position is set to the number of set pulses n + the set time n in the initial design, the respective plates may be shifted for each device.
According to the present invention, the initial setting time can be adjusted individually for each of the three plate position adjustment volumes 12a, 12b, and 12c. Therefore, if the pattern of the plate cannot be formed at the center of the medal with the initial setting time data, It is possible to adjust the deviation of each plate so that a plate pattern is formed at the center of the medal.
In FIG. 4, assuming that the medal drop position is the initial set time data, the times of the first version, the second version, and the third version before and after this point are respectively t ₁ , t ₂ , t _3. Can only move. This example shows the case where the time adjustable range can be adjusted by approximately one pulse period before and after, but the time adjusted range is subject to deviation due to wear due to use, etc., and maximum deviation occurs in one direction. The amount to be adjusted can be adjusted.

In the above embodiment, the guide guide is provided substantially vertically, and the medal original plate is dropped without being brought into contact with the guide surface. However, the guide guide is configured by a slope, and the medal original plate is slid down on the slope. Similarly, the present invention can be applied. In such a case, the number of pulses and time corresponding to the angle of the slope are set.
Although the case where a volume is used as the time adjustment means is shown, the voltage value can be changed using a slide switch or the like in addition to the volume. Furthermore, it is possible to adopt a configuration in which time is adjusted using an element that changes a current value instead of a voltage value.
