Abstract

Provided is a medal cooling device in a medal die graving device which does not make a medal buyer have uncomfortable feeling caused by the generation of heat when the medal buyer touches a medal by holding the medal which is die formed by a die forming mechanism for a predetermined period of time in the device, and then offering the medal, and which can suppress the period of time until the medal is offered to a minimum. An original medal (78) dropped through a guide rail (77) of the die forming mechanism is rolled by a rolling roller and a die fitting roller and the design of the die is transferred. The medal on which the design is formed is held by a medal receiving plate (2) of a temporary medal holding mechanism (1) for a predetermined period of time, and then ejected by use of the inclination of the medal receiving plate (2). Heat generated by a die forming motion is dissipated at the medal receiving (2). Thus, the buyer never has uncomfortable feeling when the buyer touches the medal.

Description

  The present invention relates to a medal plate marking device, and more particularly, to a device for cooling the heat of a medal generated when rolling and transferring a pattern of a plate.

2. Description of the Related Art Conventionally, there has been a medal plate stamping apparatus that sells medals formed by forming uneven patterns on a medal original plate. This device responds to a demand for obtaining medals such as event venues and related characters as a commemoration when a user visits an event venue.
FIG. 9 shows an example of the appearance of this type of medal plate marking apparatus.
A medal purchase guidance display unit 56 for explaining the process of forming a medal plate is placed above the front surface of the medal plate marking device 51. A transparent window 57 through which a medal plate forming mechanism can be seen is provided below. In front of the transparent window 57, there is a plate selection panel 54 on which plate selection buttons 54a, 54b and 54c for selecting different plates are arranged. A light emitting lamp is built in the plate selection buttons 54a, 54b and 54c.

At the bottom of the plate selection panel 54, a medal payout portion 58 having a concavo-convex pattern is disposed, and a coin insertion portion 55 is provided on the side.
A person who wants to purchase a medal first inserts a predetermined coin into the coin insertion unit 55.
In the plate forming mechanism (not shown) inside the apparatus by inserting coins, the coin original plate is supplied to the upper part between the roller having a flat rotating surface and the roller carrying the plate, and three selection buttons on the plate selection panel 54 When 54a, 54b, and 54c emit light, the medal purchaser is prompted to select and press one of buttons having different concavo-convex patterns. When the medal purchaser selects and presses one of the buttons, the coin original plate falls between a roller having a flat rotating surface and a roller on which the plate is mounted, and the selected plate is formed on the coin original plate, An uneven medal is paid out.

10 and 11 show a plate forming mechanism of the medal plate marking apparatus of FIG.
FIG. 10 is a perspective view showing the entire plate forming mechanism, and FIG. 11 is a view of the plate forming mechanism as viewed from the front.
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.

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 attached to the roller mounting plates 68 and 69 in parallel with the shaft 70, and three plates (first plate 76a and the like) are attached to the shaft 73 at intervals of approximately 120 degrees on the peripheral surface. A roller 75 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 with each other, the rolling roller 74 and the plate attachment roller 75 rotate together.
A guide rail 77 that guides the original medal plate 78 to the press contact surface is provided above the press 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 a solenoid plunger 84 enters and exits is formed in the vicinity of 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 is generated by slit counting of a rotary encoder or the like, the solenoid is driven to drop the medal original plate 78, and the plate pattern is transferred while being rolled by the plate mounted on the rolling roller 74 and the plate mounting roller 75. The medal falls. The dropped medal slides on the guide slope 81, enters the medal receiving port 85, and falls to the medal payout port 86. The purchaser receives a medal from the medal payout unit 58.

By the way, since the medal processed in this way rolls a copper metal, the metal temporarily becomes high temperature (about 50 degrees) when plastic deformation occurs. Therefore, if the purchaser takes out the medal immediately after processing, it may be uncomfortable because it is hot.
The plate forming mechanism is considered to be created and implemented by the applicant of the present application, and includes the problems described above.
Japanese Patent Laid-Open No. 2005-74854 Japanese Utility Model Publication No. 62-137626

Conventionally, Patent Documents 1 and 2 have the same configuration as a mechanism for transferring a plate to a medal of this type of medal plate marking apparatus.
However, Patent Document 1 detects rotation by using a rotary encoder to detect whether or not a master that has been subjected to platemaking has been applied to the outer peripheral surface of the plate cylinder, and the heat generated by the plate cylinder that has been applied is detected. It's not a problem. Further, Patent Document 2 is a device for transferring a concavo-convex pattern of a plate by a roller, and is not equipped with a mechanism for solving the above-mentioned problems by the present applicant. Although similar, it has little relevance to the present invention.

From the background as described above, a configuration is conceivable in which, after the transfer of the medal original plate, the temporary medal is held inside the machine and cooled before being paid out.
An object of the present invention is to create a discomfort due to heat generated when a medal is held by a medal purchaser by holding out the medal to which the plate is transferred by the plate forming mechanism for a predetermined time and then paying out the medal. It is another object of the present invention to provide a medal cooling device in a medal plate marking device that can minimize the time until the medal is paid out.

In order to achieve the object, claim 1 of the present invention drops a medal original plate and rolls the dropped medal original plate with a rolling roller having a flat rotating surface and a plate mounting roller having one or more plates mounted on the rotating surface. In the plate forming mechanism of the medal plate engraving device that creates a medal with a pattern by transferring the uneven pattern of the plate and pays out the medal, it is arranged at the medal drop position of the plate forming mechanism, and its inclination is driven to change. A medal receiving plate and a medal receiving plate driving means for discharging a medal on which a plate is formed by inclining the medal receiving plate in a horizontal state after a predetermined time from dropping the original medal plate, The medal that has been dropped in step 1 is temporarily held to release the heat of the medal.
According to a second aspect of the present invention, there is provided a guide rail for guiding the original medal plate according to the first aspect of the invention, and a solenoid plunger arranged in the middle of the guide rail and temporarily stopping the original medal plate. The solenoid is driven by signal generation to drop the original medal plate, and the predetermined time is measured from generation of the plate forming timing signal.
According to a third aspect of the present invention, in the first or second aspect, the predetermined time is 4 to 6 seconds.

  According to the above configuration, although the medal plastically deformed by rolling temporarily becomes high temperature, it is possible to solve the problem of feeling uncomfortable by lowering the temperature to a temperature that the purchaser can hold. By appropriately setting the predetermined time, it is possible to shorten the time until the medal is discharged as much as possible while lowering the temperature of the medal.

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 of a medal plate marking device to which a medal cooling device according to the present invention is applied. 2 is a front view of FIG. 1, and FIG. 3 is a left side view of FIG. The parts denoted by the same reference numerals as the structure of each mechanism part described in FIG. 10 perform the same functions. The present invention is different from the background art in that a temporary medal holding mechanism 1 is provided between the rotor mounting plates 68 and 69 for cooling the medal.
A preset number of pulses generated by the slit disk 24 provided on the surface of the gear 72 is counted, and a plate formation timing signal is generated after a preset time has elapsed after counting the pulses. The solenoid plunger 84 provided in the course of the guide rail 77 is pulled by the plate formation timing signal, and the medal original plate 78 temporarily stopped is dropped.

The medal that has dropped on the medal receiving plate 2 of the temporary medal holding mechanism 1 is held on the medal receiving plate 2 in a horizontal state for a predetermined time, and then slides down the inclined medal receiving plate 2 and falls on the medal receiving port 85. The medal that has passed the medal receiving port 85 reaches the medal payout port 86.
FIG. 4 is a diagram showing details of the temporary medal holding mechanism of the medal cooling device according to the present invention, and is an enlarged view of the temporary medal holding mechanism portion of FIG.
The medal receiving plate 2 is disposed between the roller mounting plates 68 and 69 below the pressure contact surface of the rolling roller 74 and the plate mounting roller 75. As shown by the arrow 9 a, the medal 9 having the transferred plate falls to the approximate center of the medal receiving plate 2. The upper surface of the medal receiving plate 2 has a rectangular shape, and the receiving plate support plate 8 is fixed to the center of the lower surface of the medal receiving plate 2. The receiving plate support plate 8 is mounted between the roller mounting plates 68 and 69 so as to be rotatable by a shaft 8a.

The cooling solenoid 5 is disposed on the base 66 and is driven by a plate forming timing signal. The plunger 6 of the cooling solenoid 5 is drawn by driving the solenoid. The connecting rod 7 is mounted between the roller mounting plates 68 and 69 so as to be rotatable by a shaft 7a. One end of the connecting rod 7 is rotatably connected to the end of the plunger 6 by a shaft 7c, and the opposite end is rotatably connected to the end of the receiving plate support plate 8 by a shaft 7b. .
A medal receiving plate rotation restricting member 21 having a triangular cross section is provided in the vicinity of the discharge port between the roller mounting plates 68 and 69. When the front end 2a of the medal receiving plate 2 is inclined forward, the medal receiving plate rotation restricting member 21 is abutted and stopped.

FIG. 5 is a cross-sectional view taken along the line AA of FIG. 3, where (a) shows a state where the solenoid is driven, and (b) shows a state where the solenoid is not driven (OFF state).
In a normal state, the cooling solenoid 5 is in an off state as shown in FIG. 5B, and the plunger 6 is in a protruding state, and the medal receiving plate 2 is inclined and the medal can be discharged.
When the cooling solenoid 5 is driven by the plate formation timing signal, the plunger 6 is attracted, so that the connecting rod 7 rotates in the clockwise direction, and the receiving plate support plate 8 rotates in the counterclockwise direction, as shown in FIG. The receiving plate 2 is in a substantially horizontal state.
Since the medal falls in this horizontal state, it stops on the medal receiving plate 2. The time to stop for cooling the medals is set to, for example, 5 seconds (from the generation of the plate formation timing signal), and the cooling solenoid 5 is turned off after 5 seconds from the drive, and the medal receiving plate 2 is moved as shown in FIG. Tilt and eject the medal 9.

In the plate forming mechanism of this embodiment, the stopping time is 5 seconds, but the heat of the medals is surely released so that the purchaser does not feel uncomfortable, and the buyer is speedy without giving a long waiting time. Since an appropriate time during which medals can be discharged is set, it is preferable to set the stop time within the range of 4 to 6 seconds. When setting the time to stop longer than the above time due to the structure of the plate forming mechanism (the time from when the original plate is dropped and the plate is transferred when the plate forming timing signal is generated and the medal is dropped onto the medal receiving plate) Or may be set shorter.
FIG. 6 shows an arrangement structure in a medal plate stamping device case to which the medal cooling device according to the present invention is applied. A part of the case of the medal plate engraving apparatus is shown broken away. The state where the medal receiving plate 2 is inclined is shown. Further, the cooling efficiency can be improved by providing the cooling fan 20 on the wall of the medal plate stamping device casing.

FIG. 7 is a block diagram showing a circuit configuration of a medal plate marking apparatus to which the medal cooling apparatus according to the present invention is applied.
Each circuit unit is mounted on the control board 10, and a ROM 18, a RAM 19, and a nonvolatile memory unit 23 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 and the solenoid (cooling solenoid) 5 for the temporary medal holding mechanism are respectively connected. Further, an A / D converter 13 for A / D converting the analog voltage from the plate position adjusting volume 12 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 23 stores the set pulse number data and the set time for the plate. This set time data can be changed back and forth around the time preset by the plate position adjusting volume 12. The plate position adjusting volume 12 can independently adjust the set time data t in order to set a plate position or the like in individual manufacturing at the time of assembling the apparatus to a normal position.
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 a control program from the ROM 18 to realize each functional unit such as a pulse number counting unit and a time measuring unit for transferring the plate in addition to the plate forming control unit.

The plate forming control unit manages and controls the entire apparatus. Control of the plate forming mechanism unit for coin insertion, calculation control for input from the plate position adjusting volume 12, origin position detecting optical sensor 4 and position detecting unit. Input / output control of the optical sensor 3 and drive control for the medal escrow solenoid 11, the cooling solenoid 5, and the plate rotation motor 61 are performed.
The plate formation control unit sends a solenoid drive signal (plate formation timing signal) to the solenoid control input / output circuit 15 when the time measured by the time measurement unit reaches t.

FIG. 8 is a flowchart for explaining the flow of the operation of the medal plate marking apparatus to which the medal cooling apparatus according to the present invention is applied. Details of the medal cooling process in the process of plate formation will be described below with reference to FIGS. 1, 2, 4, 4, 5, 7 and 9. FIG. The step portion surrounded by the two-dot chain line is the portion 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 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 turns on the light emission lamps of the three plate selection buttons on the plate selection panel 54 that can select different patterns, and prompts the medal purchaser to press the desired plate selection button.

When the plate is selected (S004), the plate formation control unit 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 through the gears 71 and 72, and the rolling roller 74 and the plate mounting roller 75 start rotating, and the slit disk 24 also starts rotating.
The initial position of the plate mounting roller 75 is a state in which the blade 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 is moved. When the blade passes, an origin position detection signal is output from the light receiving element portion of the position detecting optical sensor 4.

Upon receiving the origin position detection signal, the plate formation control unit resets the pulse number measurement unit (counter) 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). The plate formation control unit reads the set pulse number data from the nonvolatile memory unit 23 and determines whether the pulse counting unit counts the set pulse number. When the set pulse number is counted, the time is then counted from the time when the set pulse number is counted by the time measuring unit. It is then determined whether the set time has been counted (S008). When the set time is counted, the plate forming control unit outputs a plate forming timing signal to the solenoid control input / output circuit 15, and the solenoid control input / output circuit 15 drives the medal escrow solenoid and retracts the plunger 84. Thereby, the original medal plate 78 falls in the guide rail 77 (S009).

The solenoid control input / output circuit 15 also drives the cooling solenoid 5 to rotate the medal receiving plate 2 from the inclined state to the horizontal state. Thereby, the medal receiving plate 2 stands by in a state of receiving the falling medal (S010). The original medal plate 78 dropped on the guide rail 77 is rolled to transfer the plate (S011), and the processed medal falls to the lower part of the plate forming mechanism.
The plate formation control unit measures whether or not a predetermined time, that is, 5 seconds has elapsed since the generation of the plate formation timing signal, that is, whether the medal original plate has been dropped and rolled and placed on the medal receiving plate for 5 seconds (S012). When 5 seconds have elapsed, the plate formation control unit outputs a signal indicating the progress and turns off the cooling solenoid 5. Since the plunger 6 protrudes, the medal receiving plate 2 in the horizontal state is inclined (S013), and the medal that stops on the medal receiving plate 20 and releases the heat slides down and moves from the medal receiving port 85 to the medal payout port 86 ( S014). The medal purchaser can take out medals from the medal payout unit 58.
The medal receiving plate driving means is constituted by a plate formation control unit by the CPU and a temporary medal holding mechanism.

  In the above-described embodiment, the example of using the plate formation timing signal as the timing for starting the predetermined time measurement for cooling the medal has been described. If it is configured to take out the timing of dropping on the receiving plate as a signal, the timing of dropping the medal on the medal receiving plate may be used. In addition, an example in which the medal receiving plate that has been tilted by the plate formation timing signal is set in a horizontal state to prepare for the medal dropping has been described. Then, the medal receiving plate can be returned to the horizontal state thereafter.
