As shown in Fig. 7, the shaft 70 is fixed with a calender roll 74, and a gear 71 is attached to the end of the shaft 70. The shaft 73 is rotatably attached to the roller attachment plates 68 and 69 in parallel with the shaft 70, and three plates (first plate 76a, second plate 76b, and the first plate) are attached to the peripheral surface at intervals of approximately 120 degrees. Version 3 76c) version of the mounting roller 75. Further, a gear 72 that is engaged with the gear 71 is attached to the end of the shaft 73. First edition 76a, second edition 76b and third The plate 76c is provided with irregularities that can imprint different patterns.

The motor rotational force transmitted to the shaft 70 is transmitted to the gear 72 via the gear 71, thereby rotating the plate mounting roller 75. The circumferential surface of the calender roll 74 and the plate of the plate mounting roll 75 are formed to be pressed, and the calender roll 74 and the plate mounting roll 75 are co-rotating.

A guide rail 77 that guides the commemorative coin stock plate 78 to the crimping surface on the crimping surface portion of the calender roll 74 and the plate mounting roller 75 is provided on the roller mounting plates 68, 69. The guide rail 77 is a configuration in which a long groove is formed in the vertical direction, and the commemorative coin stock plate 78 is confined while being restricted by the long groove side wall. A transparent plate (not shown) is attached to the long groove to prevent the commemorative coin stock plate 78 from flying out.

A through hole 77a through which the plunger 84 of the electromagnetic coil can enter and exit is formed in the vicinity of the upper portion of the guide rail 77. When the plunger 84 of the electromagnetic coil protrudes from the through hole 77a, the commemorative coin stock sheet 78 sent via the commemorative coin stock sheet feed hopper (not shown) stops in the guide rail 77, and the electromagnetic coil drives the plunger 84. The commemorative coin stock sheet 78 is dropped on the crimping faces of the calender rolls 74 and the plate mounting rolls 75 when retracted.

The plate forming timing signal for the commemorative coin raw material plate 78 is formed by the cam 80 shown in Figs. 8 to 10. The cam 80 is a shaft fixed to the back side of the gear 65.

When assembling the gear, the assembly may be biased, and the rolling may be repeated. How much will still cause the version of the bias. Therefore, it is necessary to adjust so that the position of the plate conforms to the unevenness of the cam portion.

[Patent Document 1] JP-A-2005-74854 (Patent Document 2)

In the above-described structure for detecting the position of the commemorative coin-plate forming mechanism, since the cam is attached to the rotating shaft and the position of the mechanical switch is detected by the unevenness of the cam, the unevenness of the cam is always constant, so the plate is 1 At this time, the adjustment of the cam can correct the deviation of the plate. However, when the plurality of plates are mounted on the rotating shaft, if the plurality of plates are to conform to the shape of the cam (concavity and convexity) at the same time, the plate mounting roller having the plurality of plates may be mounted on the plate mounting hole 760a due to the individual difference of the plate. The position of the pattern is different. In most cases, it is difficult to determine the proper position of the plate. In addition, due to the manufacturing deviation of the plate produced during the production of the plate, the plate is mounted on the assembly caused by the machine or the gear bite. The influence of deviations, etc., is very difficult to locate the correct position of all the plates.

In addition, the above-mentioned plate forming mechanism is an invention created by the applicant of the present invention, which has the above problems.

In the case of detecting the rotation by a rotary encoder from the viewpoint of a printing device using an encoder, it is possible to detect whether or not the main body of the plate is placed on the outer peripheral surface of the plate (Patent Document 1), but the applicant of the present invention A comparison of the above techniques revealed that it has little relevance to the present invention.

Further, there is a technique of Patent Document 2 for performing uneven pattern transfer using a device for forming a relief pattern of a roll, but there is no disclosure of a technique for accurately detecting a position of publication.

The object of the present invention is to provide a pulse using position detection by an optical sensor without using a cam method for mechanically performing position detection. The punching mode electrically detects the position information of the rotating shaft, and sets the pulse number information in accordance with the position of each version in advance, so that the correct position of the forming can be separately determined for each version (the position of the pattern can be formed in the center of the original sheet of the commemorative coin) ) The position adjustment mechanism of the commemorative coin version imprinting device.

In order to achieve the above object, the first aspect of the patent application of the present invention is to stop the commemorative coin raw material sheet at a designated position of the guide rail, and to use the plate rotary driving means to make the rotating surface flat and the rotating surface is provided with one plate. The above-mentioned plate mounting roller rotates at the same time, and the commemorative coin raw material plate which is stopped is moved to the contact surface of the calender roll and the plate mounting roller according to the plate forming timing signal, and the commemorative between the calender roll and the plate mounting roller is sandwiched. The commemorative coin-type embossing device for carrying out the embossing of the commemorative coins by the embossed coins of the commemorative coins An optical sensor for position detection in which a disk having a plurality of narrow grooves is provided on a peripheral surface of the plate mounting roller and a narrow groove is detected, and a circumferential surface of the disk having the plurality of narrow grooves is provided.

When the position detecting optical sensor detects the reference piece, the number of pulses from the position detecting optical sensor to the narrow groove in the vicinity of the target position set in advance corresponding to the plate is detected. The measurement is performed when the plate position at the time when the predetermined number of pulses is measured is outputted by a predetermined time. a timing signal generating means for the machine signal; and a time adjusting means for adjusting the preset time by operating the start knob, and adjusting the time by the time adjusting means to generate the above-mentioned position of the mounting roller of the plate The version of the timing signal is formed so that the pattern is formed in the center of the fallen commemorative coin.

According to a second aspect of the invention, the guide rail according to the first aspect of the invention is characterized in that the guide rail is provided with a guide member in a substantially vertical direction, so that the commemorative coin raw material sheet can be moved by its own weight. The guide rail is provided with an electromagnetic coil close to the above-mentioned guide rail for allowing the plunger to move back and forth according to the timing signal of the above-mentioned plate, and is configured to stop the commemorative coin raw material plate from falling when the plunger end portion protrudes in the middle of the guide rail. When the plunger is inserted into the above, the commemorative coin raw material board can be dropped.

According to a third aspect of the invention, in the third aspect of the invention, the one or more versions of the invention are three, and the plate forming timing signal generating means includes: When the home position detecting optical sensor detects the reference piece, it is possible to detect the vicinity of the target position set in advance by the optical position sensor for detecting the origin position. The pulse number calculation means for calculating the number of pulses until the narrow groove is calculated; and the plate position when the number of pulses set in advance for each plate is calculated for each of the plates by the pulse number calculation means is set in advance The time measuring means for measuring the time is configured to activate the electromagnetic coil for each plate.

According to a fourth aspect of the invention, in the invention described in claim 3, the time adjustment means is : a corresponding position is arranged in the position adjustment potentiometer in the device; a knob corresponding to the rotation of the potentiometer corresponding to each of the plates is set in advance to adjust the time adjustment unit; and the electromagnetic adjustment is started after the time adjustment unit adjusts the time The electromagnetic coil control unit of the coil is configured.

According to the above configuration, it is possible to eliminate the offset of the plate position and the cam shape of the cam mode (mechanical position detection). That is, the error in the manufacturing of the plate produced at the time of plate making, the variation in the assembly when the plate is mounted on the machine, and the assembly variation caused by the assembly such as the gear biting are individual adjustable plate positions. In addition, when a plurality of rolling operations are performed, the plate may be somewhat biased. However, by adjusting the position information of the pulse at this time, it is possible to avoid the adjustment of the cam position by the decomposition, and it is possible to easily correspond to the plate offset.

In addition, when the version is offset, the calender position can be easily changed by correcting the position information of the plate.

Fig. 2 is a block diagram showing the circuit configuration of a commemorative coin printing apparatus using the position adjusting mechanism of the present invention.

Each circuit unit is mounted on the control circuit board 10. The CPU 14 is connected to the ROM 18, the RAM 19, and the non-volatile memory unit (Non-Volatile). Memory; NVM) 20. Further, the CPU 14 is connected to a motor drive unit 17 formed by a switch for driving a switch of a plate rotation motor (plate rotation drive means) 61, and a sensor for detecting the origin position detecting sensor 4 and the position detecting optical sensor 3, respectively. The sensor controls the input/output circuit 16, and the electromagnetic coil control input/output circuit 15 for controlling the coin suspension electromagnetic coil 11. Further, the CPU 14 is connected to an A/D converter 13 that converts analog voltages from the three plate position adjusting potentiometers 12a, 12b, and 12c into A/D voltages.

The ROM 18 stores a control program for driving the plate forming mechanism and various data used when the control program is driven.

The non-volatile memory unit 20 stores set pulse number data n ₁ , n ₂ , and n ₃ set for three plates and set time data t ₁ , t ₂ , and t ₃ set for three plates, respectively. The set time data is changed before and after the preset position adjustment potentiometers 12a, 12b, and 12c are centered on the time set in advance. Each of the position adjustment potentiometers 12a, 12b, and 12c can adjust the set time data t ₁ , t ₂ , t independently for each plate in order to adjust the offset of the individual manufactured plates when the device is assembled to the correct position. ₃ .

The RAM 19 is used as a work area when the CPU 14 performs calculations and the like, and the RAM 19 temporarily stores data.

The CPU 14 reads out the control program from the ROM 18 and executes the functional units of the plate forming control unit 14a, the pulse number calculating unit 14b, the time measuring unit 14c, and the time adjustment calculating unit 14d.

The plate forming control unit 14a is a management and control of the entire execution device, that is, a control for executing the plate forming mechanism portion corresponding to the coin input, and an arithmetic control corresponding to the input from the plate position adjusting potentiometer 12, and the original The input/output control of the point position detecting optical sensor 4 and the position detecting optical sensor 3, the drive control of the commemorative coin suspension electromagnetic coil 11 and the plate rotation motor 61, and the like.

When the knobs of the position adjustment potentiometers 12a, 12b, and 12c are operated, the analog voltage that has been manipulated and changed is converted into a digital voltage by the A/D converter 13. The time adjustment calculation unit 14d calculates the time-varying portion of the digital voltage, and updates the set time data t ₁ , t ₂ , and t ₃ that have been set in advance in the non-volatile memory unit 20 .

The pulse number calculating unit 14b calculates the number of pulses generated by the narrow position detected by the pulse position detecting optical sensor 3 from the origin position.

The time measuring unit 14c starts the measurement time from the time point when the number of pulses calculated by the pulse number calculating unit 14b becomes n ₁ , n ₂ , and n ₃ . Version control portion 14a is formed at the time measuring unit 14c measured time becomes t _1, t _{2, 3} t, the output of the solenoid control circuit 15 sends a solenoid driving signal (timing signal forming Edition).

Figure 3 is a flow chart for explaining the molding process of the commemorative coin of the present invention. Hereinafter, the details of the plate forming process will be described with reference to FIGS. 1 , 2 , 5 , and 6 . The steps surrounded by the dashed lines are part of the process directly related to the present invention.

When the commemorative coin purchaser inputs the 100-dollar coin in the coin-input unit 55, the plate forming control unit 14a confirms that the coin inserted is a predetermined coin [step (hereinafter referred to as "S") 001]. As a result, the commemorative coin feeding hopper which accumulates the commemorative coin sheet of most commemorative coins starts to discharge one commemorative coin raw material sheet 78 at the entrance of the guide rail 77 (S002). Commemorative coin raw material board 78 is dropped along the guide rail 77, but the commemorative coin stock plate 78 is stopped to descend downstream due to the plunger 84 of the commemorative coin suspension electromagnetic coil protruding from the guide rail 77 (S003).

On the other hand, the plate forming control unit 14a lights up the light bulbs of the three plate selection buttons on the pattern selection panel 54 that can select different patterns, thereby urging the commemorative coin purchaser to press the desired plate selection button.

When the plate forming control unit 14a confirms that the commemorative coin purchaser has executed the plate selection (S004), the drive signal is sent to the motor drive unit 17 to rotate the plate rotation motor 61 according to the signal transmitted from the pattern selection button ( S005).

The rotational force of the plate rotation motor 61 is transmitted to the chain 64 through the transmission shaft 62 and the gear 63, and is transmitted to the shaft 70 after the gear 65 is decelerated. The rotation of the shaft 70 is transmitted to the shaft 73 through the gears 71 and 72, and the rolling roller 74 and the plate mounting roller 75 start to rotate, and the narrow grooved disk 24 also starts to rotate.

The initial position of the plate mounting roller 75 is a state in which the optical pickup 4 for the home position detection stops the reference piece 5 at a predetermined angle, and starts to rotate from the position, and the reference piece 5 passes the position detecting optical. In the sensor 4, the origin position detecting signal is output from the light receiving element portion of the position detecting optical sensor 4.

When the plate forming control unit 14a receives the origin position detecting signal, the number of the pulse number measuring unit (calculator) 14b is reset to zero, and the pulse number measuring unit starts the pulse detected by the position detecting optical sensor 4. The number is calculated (S006).

Then the version rotation is started (S007). Version control unit 14a forming, for example, when the selected version of the first version 76a will set the number of pulses n ₁ from the non-volatile memory unit 20 reads out the data, whether the pulse counting section 14b calculates the number of pulses reaches the set data for n ₁ Decision (S008). When the calculation reaches the set pulse number data n ₁ , the time is calculated by the time measuring unit 14 c from the time point when the set pulse number data n ₁ is calculated. Next, it is determined whether or not the calculated time reaches the set time data t ₁ (S009). When the calculated set time of data at t _1, the control unit 14a will EDITION molded solenoid control circuit 15 outputs the output timing signal EDITION molded d _1, the output of the solenoid control circuit 15 drives the electromagnetic coil suspended coins Retracted into the plunger 84. As a result, the commemorative coin stock sheet 78 is dropped along the guide rail 77 (S010).

In the above operation, if the selected version is the second version 76b, the set pulse number data n ₂ and the set time data t _{2 are used} , and if the selected version is the third version 76c, the set pulse number data is used. ₃ and set the time data t ₃ .

The fallen commemorative coin stock sheet 78 is sandwiched between the calender roll 74 and the plate front end position of the platen roller 75, and the commemorative coin stock plate 78 is rolled while being formed in the center of the commemorative coin stock plate 78. Version of the pattern (S011).

The calendered commemorative coin is dropped on the lower portion of the plate forming mechanism, and is slid down the ramp to the commemorative coin selling portion 58 (S012). When the plate forming control unit 14a drops the commemorative coin, the plate mounting roller 75 stops the motor when the plate mounting roller 75 returns to the initial position at which the rotation starts (S013).

Fig. 4 is a timing chart for explaining the position adjustment of each version.

As is apparent from the figure, the circumferential portion of the narrow grooved disk 1 is expanded in the time axis direction to describe the pulse generated by the narrow groove. For each version, although the origin detection position is the same position, the number of pulses generated from the origin detection position is n ₁ , n ₂ , and n ₃ , respectively, and the time after the number of set pulses is calculated is t ₁ , t ₂ , t ₃ . Therefore, for the first edition, the second edition, and the third edition, the origin detection starts to (pulse number n ₁ + time t ₁ ), (pulse number n ₂ + time t ₂ ), (pulse number n ₃ + The distance (rotation angle) rotated by the time version until time t ₃ ) is output, and the timing signal for the commemorative coin drop is output. In the case where the speed of the motor is always constant and the other mechanical elements are of the original size or there is no assembly deviation, the version of the commemorative coin rolling operation will form the pattern in the center of the commemorative coin with the time data set at the beginning.

However, the actual situation is that there is a variation in the manufacturing of the plate when the plate is made. When the plate is mounted in the machine or the gear is engaged, the assembly may be biased, and the rolling action may be repeated. Caused the version of the bias. Therefore, even if the original design is to set the appropriate position for the set pulse number n + set time t, for each device, the respective version still has a bias problem.

According to the present invention, since the plate position adjusting potentiometers 12a, 12b, and 12c of the three plates can respectively adjust the initial setting time, if the original setting time data cannot make the pattern of the plate form in the center of the commemorative coin, The offset of each version can be adjusted separately so that the pattern of the version is formed in the center of the commemorative coin.

In Fig. 4, if the commemorative coin drop position is the original set time data, then only the t _{1 can} be adjusted for the time of the first edition, the second edition, and the third edition, respectively, based on the data. t ₂ , t ₃ . In this example, it is revealed that the time adjustment range is such that the amount of the first pulse period can be adjusted back and forth. However, the time adjustment range also takes into account the deviation due to wear and the like, so the time adjustment range is configured to be adjustable in one direction. The maximum amount of offset produced.

In the above embodiment, the example in which the guide rail is placed substantially perpendicularly and the commemorative coin stock plate is dropped without contacting the guide surface has been described. However, the guide rail has a sloped surface and the commemorative coin stock sheet is slid down on the inclined surface. The invention is applied. In this case, the number is set in accordance with the number of pulses or time that can correspond to the slope angle.

Although the time adjustment means is exemplified by the use of a potentiometer, in addition to the potentiometer, the voltage value can be changed using a toggle switch or the like. Further, the current value is not limited to the voltage value, and the current value changing element may be used to adjust the time.
