Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rotary solenoid drive transmission mechanism and a coin processor using the same.
[0002]
[Prior art]
Conventionally, Japanese Patent No. 28386641 is known as an apparatus that is incorporated in a sorting unit of a coin processing machine and stops, passes, and distributes coins being conveyed. This device includes a pair of projecting members that can be projected on a coin conveyance path, and activates these projecting members according to the result of discrimination in the discrimination section. By controlling the operation of each projecting member, The coins that are conveyed are stopped, passed, or sorted. A rotary solenoid is used to rotationally drive these protruding members.
[0003]
[Problems to be solved by the invention]
However, when the rotary solenoid is operated, the transmission member that transmits the rotation to the protruding member vigorously collides with the restriction stopper pin, and sometimes bounces momentarily due to the repulsive force. That is, when the projecting member is projected into the transport path to prevent the passage of coins, if the transmission member collides with the restricting stopper pin on the projecting side, the repulsive force causes the transmission member to reversely rotate momentarily, The projecting member is retracted for a moment. Then, at that moment, there was a problem that a coin that wanted to be blocked passed through. On the other hand, when the protruding member is retracted from the conveyance path so as to allow the coin to pass, the transmission member collides with the restriction stopper pin on the retraction side, and the repulsive force causes the transmission member to reversely rotate momentarily, thereby conveying the coin. The protruding member protrudes into the road. Then, there was a problem that the coins to be passed were stopped.
[0004]
Accordingly, an object of the present invention is to provide a rotary solenoid drive transmission mechanism capable of ensuring accurate operation performance by preventing bouncing when rotation is restricted by a regulating stopper member or the like, and a coin processor using the same. And
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a rotary solenoid drive transmission mechanism of the present invention includes a rotary solenoid, a transmission member that is rotationally driven by the rotary solenoid, a brake member that is pressed against the transmission member, A braking stopper member capable of restricting movement, and the braking stopper member abuts against the brake member during the rotational drive of the transmission member by the rotary solenoid to restrict the movement of the brake member, A rotational resistance is generated in the transmission member by a frictional force between the transmission member and the brake member.
[0006]
As a result, when the transmission member is rotationally driven by the rotary solenoid, the brake member pressed against the transmission member rotates integrally, but the brake member abuts against the braking stopper member during the rotational driving and moves. Is regulated. As a result, the rotationally driven transmission member is subjected to a rotational resistance due to the frictional force between the transmission member and the brake member to be stopped, and the brake is applied. Therefore, when the transmission member is finally brought into contact with the regulating stopper member and its rotation is restricted, the momentum of the rotation is weakened and does not bounce.
[0007]
The coin processor of the present invention is characterized in that the rotary solenoid drive transmission mechanism is provided in a coin passage through which coins are conveyed so as to restrict and / or change the movement of coins.
[0008]
As a result, the rotary solenoid drive transmission mechanism does not bounce when stopped, so that the coins conveyed through the coin passage are reliably operated.
[0009]

And a third straight line portion 24.
[0013]
Above the coin passage 15, a transport unit 26 that transports the coins on the coin passage 15 along the coin passage 15 is provided. The transport unit 26 includes a transport belt 27 that moves the coins fed from the rotary disk 14 along a part of the first straight portion 20, the first bent portion 21, and the second straight portion 22, and the transport belt 27. A conveyor belt 28 that partially overlaps and moves coins along the remaining part of the second linear portion 22, the second bent portion 23, and the third linear portion 24, and power from a motor (not shown) to the conveyor belt 27, The belt 29 is transmitted to the belt 28, and both are configured to be able to rotate forward and backward in conjunction with each other.
[0014]
Between the rotary disk 14 and the first straight portion 20 of the coin passage 15, coins that collide with and stay on the tip of the guide 16 are placed in the rotary disk 14 at the tip of the guide 16. A rotatable guide roller 30 is provided to facilitate return to the coin passage 15 or to guide it to the coin passage 15.
[0015]
A material detection sensor 31 that detects the material of the coins conveyed on the first straight part 20 from the magnetic property is provided on the first straight part 20 on the upstream side in the coin conveyance direction of the coin passage 15. It is arranged so as to constitute a part of. On both sides of the material detection sensor 31, coin detection sensors 31a and 31b are provided for measuring the timing of the detection of the detection data by the material detection sensor 31. That is, the material detection sensor 31 takes in the detection data when coins are detected by the coin detection sensors 31a and 31b.
[0016]
In addition, on the first bent portion 21 side of the second straight portion 22 on the downstream side of the coin passage 15, an image detection unit 32 that detects an image of a coin conveyed by the second straight portion 22 is provided on the passage surface 18. Arranged to form part. Note that coin detection sensors 32 a and 32 b are provided on both sides of the image detection unit 32 to measure the timing of capturing of detection data by the image detection unit 32. That is, the image detection unit 32 takes in the detection data when coins are detected by the coin detection sensors 32a and 32b.
As a result, the determination unit 33 including the material detection sensor 31 and the image detection unit 32 is disposed across the first linear portion 20 and the second linear portion 22 of the coin path 15.
[0017]
Here, the outputs of the material detection sensor 31 and the image detection unit 32 are input to a discrimination circuit (not shown). In the discrimination circuit, for example, detection data for detection coins of the upstream material detection sensor 31 is input. If the material detection data is compared with the reference data of the material of each denomination coin in order with the reference data of the material of the coin of each denomination, and if it is determined that the reference data of the material of any denomination coin does not match, Determine. On the other hand, if it is determined that it matches the reference data of the coin material of any denomination, then the reference data of the coin image of the coined material is read, and the same detection as the reference data of this image It compares with the detection data of the image detection part 32 with respect to a coin, and detects whether these correspond. When it is determined that the reference data and the detection data of these images match, it is determined that the detected coin is a true coin of the detected denomination, while the reference data and the detection data of these images Are determined not to match, it is determined that the detected coin is a fake coin.
[0018]
On the downstream side of the image detection unit 32 of the second linear part 22, counting projecting members 36 a and 36 b are provided on both sides of the second linear part 22. These counting projecting members 36a and 36b are mainly used as counting stoppers. When the required number of coins reaches a predetermined number, both of them rotate by rotating around an axis perpendicular to the passage surface 18. At the same time, the coins that protrude into the second linear portion 22 and block the coins conveyed by the second linear portion 22 are blocked (that is, the coins on the upstream side of the counting protruding members 36a and 36b are stopped). The passage of coins retracted from the two straight portions 22 and conveyed by the second straight portions 22 is allowed.
[0019]
Further, these counting projecting members 36a and 36b are not only used for counting, but also by a discrimination circuit (not shown), even if a coin to be conveyed is a true coin of any denomination, it is a false coin. It operates even when it cannot be discriminated, and it can be prevented from passing. After the counting projection members 36a and 36b are actuated, the conveyor belts 27, 28 and 29 are rotated in the reverse direction, and all the coins located upstream from the counting projection members 36a and 36b are rotated. Return to disk 14.
[0020]
Furthermore, coin detection sensors 37a and 37b for measuring the timing for driving the counting projection members 36a and 36b are provided at positions immediately upstream of the counting projection members 36a and 36b in the second linear portion 22. Yes. That is, if the counting projection members 36a and 36b are projected to the second linear portion 22 at the timing when the intended coins are detected by the coin detection sensors 37a and 37b, the intended coins are stopped. .
[0021]
On the downstream side of the counting projecting members 36a, 36b in the second linear portion 22, a reject unit 40 that excludes coins that are determined to be fake coins based on the detection results of the determination unit 33 including the material detection sensor 31 and the image detection unit 32. Is provided. The reject portion 40 is provided on the guide hole 17 side of the reject hole 41 formed in the passage surface 18 of the second straight portion 22 and the upstream end position of the reject hole 41 in the coin transport direction. And a reject projecting member 42 that protrudes into and retracts from the second straight line portion 22 by rotating about an axis perpendicular to 18.
[0022]
Here, when the reject projecting member 42 is in the retracted position retracted from the second linear portion 22, the coin passing through the reject portion 40 comes into contact with the guide 17 on the side where the reject projecting member 42 is provided. Thus, the conveyor belt and the coin passage are set so as to move smoothly, and the width of the reject hole 41 is set smaller than the diameter of the smallest coin to be handled.
[0023]
When the coins determined to be true coins by the detection result of the determination unit 33 are allowed to pass, the reject projecting member 42 is in the retracted position retracted from the second linear portion 22 and is always in contact with the guide 17. The moving coin is prevented from falling into the reject hole 41, passes through the reject hole 41, and further moves downstream in the second linear portion 22.
[0024]
On the other hand, when the coins determined to be fake coins from the detection result of the determination unit 33 are removed from the coin passage 15, the reject projecting member 42 is positioned at the projecting position projecting into the second linear portion 22. The coin that has been moved while being in contact with the contact 17 comes into contact with the reject projecting member 42 and is pushed by this to move away from the guide 17, and as a result, it falls into the reject hole 41. It has become.
[0025]
Further, a coin detection sensor 43 for measuring the timing for driving the reject projecting member 42 is provided at a position immediately upstream of the reject projecting member 42 in the second linear portion 22. That is, if the reject projecting member 42 is protruded from the second linear portion 22 for a predetermined time at the timing when the target coin is detected by the coin detection sensor 43, only the target coin is dropped into the reject hole 41. It will be.
[0026]
As described above, the reject unit 40 causes the coins that have been determined to be fake coins to drop into the reject hole 41 by causing the reject projecting member 42 to project into the second straight part 22, and from the second straight part 22. On the other hand, the coin determined to be a true coin is not dropped into the reject hole 41 and is conveyed further downstream in the second linear portion 22 by not projecting the reject projecting member 42 into the second linear portion 22. .
[0027]
Here, the coins dropped from the reject hole 41 are collected in a reject box disposed below the reject hole 41, although illustration is omitted. Then, after the operator takes out the reject box from the coin wrapping machine, the false coin is taken out from the reject box.
[0028]
On the downstream side of the reject part 40 in the second straight line part 22, the coins determined to be true coins and different denomination coins other than the specified denomination based on the detection results of the material detection sensor 31 and the image detection part 32 are excluded. A sorting unit 45 is provided. The sorting unit 45 has the same structure as the reject unit 40, and the sorting hole 46 formed in the passage surface 18 of the second straight portion 22 and the upstream end of the sorting hole 46 in the coin transport direction. Provided on the guide 17 side of the position, and a projecting member 47 for sorting which can be projected into and retracted from the second linear portion 22 by rotating around an axis perpendicular to the passage surface 18. are doing.
[0029]
Here, in a state in which the sorting projecting member 47 is retracted from the second linear portion 22, the coin passing through the sorting unit 45 is moved in contact with the guide 17 on the side where the sorting projecting member 47 is provided. The conveyor belt and the coin passage are set so that the width of the sorting hole 46 is set smaller than the diameter of the smallest coin to be handled. When the sorting projecting member 47 is retracted from the second linear portion 22, coins that move while always in contact with the guide 17 are prevented from falling into the sorting hole 46 and pass through the sorting hole 46. Further, the second linear portion 22 moves to the downstream side. On the other hand, when the sorting projecting member 47 is projected into the second linear portion 22, the coin that has been moved while in contact with the guide 17 comes into contact with the sorting projecting member 47 and is pushed away from the guide 17. As a result, the transport path is shifted, and as a result, the transport path falls into the sorting hole 46.
[0030]
Further, a coin detection sensor 48 for measuring the timing for driving the sorting protrusion member 47 is provided at a position immediately upstream of the sorting protrusion member 47 in the second linear portion 22. That is, when the sorting protrusion member 47 is projected from the second linear portion 22 for a predetermined time at the timing when the desired coin is detected by the coin detection sensor 48, only the desired coin is dropped into the sorting hole 46. It will be.
[0031]
As described above, the sorting unit 45 causes the sorting projecting member 47 to project into the second linear portion 22 of a coin that is a true coin and is identified as a different denomination coin other than the designated denomination. While falling into the sorting hole 46, the second straight portion 22 is removed from the second straight line portion 22, while the coin that is determined to be a processing coin of the specified predetermined denomination to be packaged is moved to the second projecting member 47 for sorting. By not projecting into the straight portion 22, the second straight portion 22 is transported further downstream without being dropped into the reject hole 41.
[0032]
Here, the coins dropped from the sorting hole 46 are collected in a sorting box disposed below the sorting hole 46, although not shown. Then, after the operator takes out the sorting box from the coin wrapping machine, the different denomination coins are taken out from the sorting box.
[0033]
An erroneous sorting check unit 50 is provided further downstream than the sorting unit 45 of the second linear portion 22. This is for finally confirming whether the coins that have passed through the reject unit 40 and the sorting unit 45 are really true coins and are processing target coins of a specified denomination. The final confirmation is performed by the material detection sensor 51 that detects the material of the coin by the magnetic property of the coin. Similar to the material detection sensor 31 described above, coin detection sensors 51a and 51b are provided on both sides of the material detection sensor 51 for measuring the timing of the detection of detection data by the material detection sensor 51. That is, the material detection sensor 51 takes in the detection data when coins are detected by the coin detection sensors 51a and 51b.
[0034]
If it is determined that the coin that has passed through the reject unit 40 and the sorting unit 45 is not the processing target coin of the specified denomination, the entire sorting machine immediately stops and an error occurs. Visually or audibly report the occurrence.

The distribution unit 55 opens the shutter member 56 when the counting process is selected as the work content. Then, all the coins conveyed downstream from the misselection check unit 50 are dropped from the sorting holes 56a. Then, the coins dropped from the sorting hole 56a in this way are guided by the counting conveyance path 81 and the counting chute unit 80, and are fed out to an unillustrated outlet that can be taken out of the machine. On the other hand, the distribution unit 55 closes the shutter member 56 when the packaging process is selected as the work content. Then, all the coins conveyed downstream from the misselection check unit 50 are guided to the third straight portion 24 without being dropped from the sorting hole 56a.

And rotate in opposite directions. That is, the coins supplied through the third linear portion 24 are put on the protrusions 74 and 74 of the accumulation drums 75 and 75 in a state where the movement in the front-rear direction is restricted by the front restriction plate and the rear restriction plate, As a result of the accumulation drums 75 and 75 being rotated by one rotation, the coins supplied thereafter are stacked on the preceding coins, so that a plurality of coins move up and down between these accumulation drums 75 and 75 and between the regulating plates. Accumulated coins are formed by being stacked in the direction.

The base member 101 is provided with a sensor 129 that detects the presence or absence of the contact portion 125 of the brake member 107. The sensor 129 is disposed at a position where the contact portion 125 is detected when the brake member 107 contacts the protruding braking stopper member 110. In other words, the sensor 129 detects the brake member 107 immediately before the reject projecting member 42 completely projects when the reject projecting member 42 projects into the coin passage 15, so that the reject projecting member 42 becomes a coin. On the other hand, if the brake member 107 immediately before the reject projecting member 42 completely projects cannot be detected, it is determined that the reject projecting member 42 cannot project into the coin channel 15 while it is determined that the projecting member 42 has normally projected. .
[0054]
Next, the operation when the reject projecting member 42 is driven by the rotary solenoid drive transmission mechanism 100 will be described.
[0055]
As shown in FIG. 2, when the coin C determined to be a false coin by the determination unit 33 is conveyed through the coin passage 15 and reaches the position of the reject unit 40, the coin detection sensor 43 detects the coin at the timing. The rotary solenoid 102 is driven in one direction so as to project the reject projecting member 42.
[0056]
Then, as shown in the order of FIGS. 4 to 5, the first transmission member 103 rotates integrally with the drive shaft 117 in a predetermined direction (clockwise direction in FIGS. 4 and 5), and the gear 120 has a gear 124. The second transmission member 104 that meshes with the reject projecting member 42 is rotated in the reverse direction (counterclockwise direction in FIGS. 4 and 5). During this rotation, as shown in FIG. 5, the brake member 107 that has been rotated integrally with the first transmission member 103 comes into contact with the protruding-side braking stopper member 110 at the contact portion 125, and further rotates. Will be regulated.
[0057]
On the other hand, the rotation of the drive shaft 117 of the rotary solenoid 120 is still halfway, and the first transmission member 103 fixed to the drive shaft 117 continues to rotate as shown in the order of FIGS. Since the member 107 is stopped, a frictional force due to the urging force of the compression spring 127 is generated between the first transmission member 103 and the brake member 107, and rotational resistance is generated. Due to this rotational resistance, the first transmission member 103, the second transmission member 104, and the reject projecting member 42 rotate slowly, and then the first transmission member 103 comes into contact with the projecting-side restricting stopper member 113, and the first The transmission member 103, the second transmission member 104, and the reject projecting member 42 are stopped, and the reject projecting member 42 is positioned at the projecting position.
[0058]
When the first transmission member 103 comes into contact with the protrusion-side regulating stopper member 113, the rotation of the first transmission member 103 is slow, so that the impact of the contact is weakened and the momentum bounces. As a result, the reject projecting member 42 is not unnecessarily moved from the coin passage 15 in the retracting direction.
[0059]
Thus, at the time of protrusion, the reject protrusion member 42 can be operated accurately, and the movement of the coins conveyed in the coin passage 15 can be changed reliably.
[0060]
In this way, after the reject projecting member 42 is positioned at the projecting position and the false coin is dropped into the reject hole 41, the reject projecting member 42 is immediately transported so as not to interfere with the coin. Return to the retracted position. That is, the rotary solenoid 102 is driven in the direction opposite to the above in order to retract the reject projecting member 42.
[0061]
Then, as shown in the order of FIGS. 6 to 7, the first transmission member 103 rotates integrally with the drive shaft 117 in the reverse direction (counterclockwise direction in FIGS. 6 and 7). The meshing second transmission member 104 is further rotated in the reverse direction (clockwise direction in FIGS. 6 and 7) together with the reject projecting member 42. During this rotation, as shown in FIG. 7, the brake member 107 that has been rotated integrally with the first transmission member 103 comes into contact with the retraction brake stopper member 111, and further rotation is restricted. Become.
[0062]
On the other hand, the rotation of the drive shaft 117 of the rotary solenoid 102 is still halfway, and the first transmission member 103 fixed to the drive shaft 117 continues to rotate as shown in the order of FIGS. Since the brake member 107 is stopped, a frictional force due to the urging force of the compression spring 127 is generated between the first transmission member 103 and the brake member 107, and a rotational resistance is generated. Due to this rotational resistance, the first transmission member 103, the second transmission member 104, and the reject projecting member 42 rotate slowly, and then the first transmission member 103 comes into contact with the retraction-side restricting stopper member 114, and the first The transmission member 103, the second transmission member 104, and the reject projecting member 42 are stopped, and the reject projecting member 42 is positioned at the retracted position.
[0063]
When the first transmission member 103 comes into contact with the retraction-side restricting stopper member 114, the rotation of the first transmission member 103 is slow, so that the impact of the contact is weakened and bounces excessively. As a result, the reject projecting member 42 does not unnecessarily project into the coin passage 15.
[0064]
In this manner, the reject projecting member 42 can be accurately operated even during retraction.
[0065]
In the above description, the rotary solenoid drive transmission mechanism 100 that drives the reject projecting member 42 of the reject unit 40 has been described as an example, but a rotary solenoid drive transmission mechanism that drives the screening projecting member 47 of the sorting unit 45, The rotary solenoid drive transmission mechanism that drives the counting projection members 36a and 36b also has the same structure except for the control contents such as the drive timing.
[0066]
In addition, the rotary solenoid drive transmission mechanism can be applied to any device using a rotary solenoid without being limited to a coin processor, and accurate operation performance can be ensured in any case. become.
[0067]
【The invention's effect】
As described above in detail, according to the rotary solenoid drive transmission mechanism of the present invention, when the transmission member is rotationally driven by the rotary solenoid, the brake member pressed against the transmission member rotates integrally. On the way, the brake member comes into contact with the braking stopper member and its movement is restricted. As a result, the rotationally driven transmission member is subjected to a rotational resistance due to the frictional force between the transmission member and the brake member to be stopped, and the brake is applied. Therefore, when the transmission member is finally brought into contact with the regulating stopper member and its rotation is restricted, the momentum of the rotation is weakened and does not bounce.
[0068]
Thus, accurate operation performance can be ensured by preventing bouncing when the rotation is restricted by a restriction stopper member or the like.
[0069]
Further, according to the coin processing machine of the present invention, since the rotary solenoid drive transmission mechanism does not bounce when stopped, the coins conveyed in the coin passage are surely operated.
[0070]
Therefore, the movement of the coins conveyed in the coin passage can be reliably regulated and / or changed.
