Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin sorter, and more specifically, to a coin throwing device for taking in coins suitable for the throwing device and excluding coins that are not suitable. It relates to a coin sorter.

[0002]

2. Description of the Related Art A conventional effect sorter will be described below with reference to FIGS. Here, FIG. 6 is a front conceptual view showing a state of a device incorporating a conventional coin sorter, and FIG. 7 is a vertical sectional view taken along line AA of the coin sorter shown in FIG.
BACKGROUND ART Conventionally, coin and token sorters include so-called cradle type and gutter type. For example, FIG. 7 shows a gutter type coin sorter. In this gutter type coin sorter, the lower end portion of a flat plate is bent at an obtuse angle to form a bottom 81, and a drop hole 82 through which a coin smaller than an appropriate size can pass is provided in the central portion of the flat plate. Scale 80 and its diameter measurement scale 8
It is formed to have a flat plate-shaped thickness measuring scale 90 which is parallel to 0 and is located on the bottom portion 81 side of the diameter measuring scale 80 at an interval slightly wider than the thickness of the coin. The interval between the diameter measuring scale 80 and the thickness measuring scale 90 forms a coin passage, and both scales 80, 90 are fixed so that the coin passage is inclined toward the diameter measuring scale 80 side. The lower end of the thickness measuring scale 90 does not reach the bottom 81 of the diameter measuring scale 80 and is located near the center of the drop hole 82, and the lower end of the lower end forms a drop assist hole 91. Although illustration is omitted, the thickness measuring scale 90 has a shaft fulcrum at its upper portion, and its lower end has a diameter measuring scale 80.
It is rotatable toward the falling hole 82 side.

In such a coin sorter, a coin 1
By using the potential energy due to its own weight of 0 to spontaneously drop or roll into the coin passage, the movement in the sorting machine and the sorting function are performed. For example, a coin having a diameter smaller than an appropriate diameter rolls down from the drop hole 82 or the drop assist hole 91 of the diameter measuring scale 80.

Although not shown in detail, for a coin having a diameter larger than an appropriate diameter or a coin having a thickness larger than an appropriate thickness, the thickness measuring scale 90 is rotated to push the front and back surfaces of the coin 10 at its lower end. , Push out from the drop hole 82.

[0005]

However, the above-mentioned conventional coin sorter has the following problems. First, the vertical size of the coin sorter is set to the coins in order to move and sort inside the sorter by spontaneously dropping or rolling into the coin passage using potential energy due to the weight of the coin. It is necessary to give enough potential energy. Therefore, there is a limit in trying to downsize the coin sorter.

Further, with reference to FIG. 7,
Due to the structure for performing the sorting function, the diameter measuring scale 80 and the thickness measuring scale 90 forming the coin passage need to be formed so as to incline toward the diameter measuring scale 80 side. This is also a restriction on the design of the coin sorting machine. Was becoming. The coin to be sorted does not move by its own weight but may be forced to move inside the coin sorter, but such a coin sorter has not been provided.

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide a coin sorter which is capable of surely sorting coins by forcibly moving the coins and has small design restrictions.

[0008]

The present invention is to achieve the above-mentioned object. The coin sorter according to claim 1 is formed to include a front and back surface supporting portion that supports one surface of a front surface and a back surface of the coin, and a coin moving portion that moves the coin along the front and back surface supporting portion. , The front and back surface support portion, a drop hole having an inner diameter slightly smaller than the diameter of a proper coin having a predetermined diameter and thickness, and parallel to the moving direction of the coin by the coin moving portion, and on both sides of the drop hole. A pair of placing edges that are positioned to support one side of the proper coin and one side of both placing edges, and move an illegal coin that is thicker than the appropriate coin toward the other placing edge. In addition to moving the illegal coin that is thinner than the proper coin toward the other mounting edge in the direction approaching it, the thickness measuring scale formed with a slanting upward slant and the thickness of the moving coin are measured. Energizing toward the slope of the scale And the coin moving unit rotates the front and back rollers and the front and back rollers that move the coin by rotating in contact with the other surface of the front and back of the coin while facing the front and back support section. It is characterized by comprising a driving unit for driving.

According to another aspect of the present invention, there is provided a coin sorter which moves a front and back surface supporting portion which supports one of front and back surfaces of the coin, and a coin moving portion which moves the coin along the front and back surface supporting portion. And a biasing portion that biases the coin downward, and the front and back surface supporting portions have a drop hole having an inner diameter slightly smaller than the diameter of a proper coin having a predetermined diameter and thickness, and A pair of placing edges that are parallel to the moving direction of the coin by the coin moving portion and are positioned on both sides of the drop hole to support one side of the proper coin, and are located on one side of both placing edges,
Move illegal coins thicker than appropriate coins toward the other loading edge, and move illegal coins thinner than appropriate coins toward the other loading edge Diagonally upward And a biasing portion that biases the moving coin toward the diagonal portion of the thickness measurement scale. It is characterized in that it is formed by including a peripheral roller for moving a coin by rotating the peripheral roller in contact with the peripheral surface, and a drive unit for rotationally driving the peripheral roller.

[0010]

[Operation] According to the coin sorter of the first aspect, the following operation is achieved. First, the drive unit of the front and back rollers of the coin moving unit operates. Then, the front and back rollers rotate while contacting one of the front and back surfaces of the coin to move the coin. The coins that move at the same time are urged by the urging portion toward the slant portion of the thickness measurement scale. The coin moves along the placement edge by the coin moving unit, and a part of the upper surface thereof contacts the slant portion of the thickness measurement scale.

When the moving coin is smaller than the diameter of the proper coin, the side opposite to the thickness measuring scale of the coin is disengaged from the placing edge, so that the coin falls from the drop hole. If the moving coin is thicker than the proper thickness of the coin, part of one side of the coin will come into contact with the slope of the thickness measurement scale, but the side of the coin that should be supported by the support part will come off the placement edge. , The coin falls through the drop hole.

When the moving coin has the same diameter as the proper coin and is thin, a part of one side of the coin comes into contact with the slant of the thickness measuring scale, and the one side is also supported by the placing edge. Due to the urging of the urging unit, the coin moves toward the back of the thickness measurement scale, and one side of the coin on the opposite side of the thickness measurement scale is disengaged from the mounting edge, so that the coin falls from the drop hole.

Thus, only coins having the same diameter and thickness as the proper coin can pass through the coin sorter of the present invention. The coin sorter according to the second aspect of the invention has the following effects. First, the drive unit of the circumferential surface roller of the coin moving unit operates. Then, the circumferential surface roller rotates while contacting the circumferential surface of the coin to move the coin.

Then, the coin moves along the placement edge by the coin moving unit, and a part of the coin comes into contact with the slant portion of the thickness measuring scale.

When the moving coin is smaller than the diameter of the proper coin, the side opposite to the thickness measuring scale of the coin is disengaged from the placing edge, so that the coin falls from the drop hole. If the moving coin is thicker than the proper thickness, a part of the coin contacts the slant part of the thickness measurement scale, but the opposite side of the contact part comes off the mounting edge. To fall.

When the moving coin has the same diameter as the proper coin and a small thickness, a part of the coin comes into contact with the slant of the thickness measuring scale, and the opposite side is also supported by the placing edge, but a circle. By the bias of the peripheral roller, it moves toward the back of the thickness measurement scale, and the front and back of the coin on the opposite side of the thickness measurement scale are disengaged from the mounting edge, so the coin is biased by the circumferential roller. , Fall from the fall hole.

As described above, only coins having the same diameter and thickness as the proper coin can pass through the coin sorter of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below with reference to embodiments and with reference to the drawings. Here, in FIG.
It is a front view of the coin sorter corresponding to the invention of claim 1, FIG. 2 is a plan view thereof, and FIG. 3 is a plan conceptual view showing a state in which the coin sorter is incorporated, It corresponds to FIG. 6 which is a conceptual front view showing the coin sorter shown in the conventional example.

Further, FIG. 4 is a front view of a coin sorter corresponding to the invention described in claim 2, and FIG. 5 is a plan view thereof. First, an embodiment of a coin sorter corresponding to the invention of claim 1 will be described. The coin sorter of this embodiment includes a front and back surface supporting portion 20 that supports the lower surfaces of the front and back surfaces of the coin 10, a biasing portion 40 that biases the coin 10, and the coin 10 along the front and back surface supporting portion 20. Coin moving part 5 for moving
It is formed with 0 and. That is, the coins 10 are horizontally moved and selected. The invention according to claim 1 is not limited to the one in which the coins are horizontally moved and selected as described above. For example, the coins may be vertically moved.

The front and back surface supporting portion 20 is a diameter measuring scale 2.
1 and a thickness measuring scale 30. The diameter measuring scale 21 has a substantially U-shaped vertical cross section.
Two parallel members are horizontal and a member connecting the two members is vertical. The bottom member supports a part of the front and back surfaces of the moving coin. The member forming the vertical surface has an inner surface height of the diameter measuring scale 21 higher than the appropriate thickness of the coin, and a through hole 22 is provided in a part thereof.

The thickness measuring scale 30 is also a member having a substantially U-shaped vertical cross section, but the diameter measuring scale 21 side is opened, and the member forming the upper surface forms an obtuse angle with the member forming the vertical surface. There is. The member forming the upper surface is the sloping portion 31. The height of the inner surface of the member forming the vertical surface is lower than the proper thickness of the coin. The distance between the bottom of the diameter measurement scale 21 and the bottom of the thickness measurement scale 30 is smaller than the proper diameter of the coin, which is used as the drop hole 29.
Both sides of the drop hole 29 serve as mounting edges. This mounting edge is
It is parallel to the moving direction of coins by the coin moving unit 50. An end of the bottom of the diameter measuring scale 21 on the side of the thickness measuring scale 30 is a mounting edge 21A, and an end of the bottom of the thickness measuring scale 30 on the side of the diameter measuring scale 21 is a mounting edge 30A.

The drop hole 29 is formed in an oval shape that is long in the moving direction of the coin 10. The drop hole 29 is not limited to the oval shape, and may be formed in an elliptical shape or a rectangular shape.
However, the length of the drop hole 29 in the moving direction does not need to be so long, and the shorter it is, the less design restrictions are required. This is because the coin moving unit 50 is forcibly moving the coin and the biasing unit 40 is pressing the coin.

The urging portion 40 comprises an urging plate member 41 and an urging spring 42 for urging the urging plate member 41, and the urging plate member 41 projects forward and backward from the through hole 22 of the diameter measuring scale 21, The urging plate member 41 urges the coin 10 toward the thickness measuring scale 30 side. The coin moving unit 50 includes a front and back surface roller 51 having an oval vertical cross section, and a roller motor 52 that rotationally drives the front and back surface roller 51. The front / back surface roller 51 is supported by a horizontal rotation shaft, contacts the upper surfaces of the front and back surfaces of the coin 10 and rotates, and moves the coin.

The material forming the surfaces of the front and back rollers 51 is preferably rubber having some elasticity and hardness. Since the coin is hard, if the surface of the front and back surface roller 51 is hard, it will be unfamiliar with the coin and it will be difficult to transfer the coin. However, if the surface of the front and back surface roller 51 is too soft, a coin thicker than an appropriate thickness This is because they will pass without being sorted. The entire front and back roller 51 may be movable up and down in order to cope with changes in the thickness of coins.

The operation of the above embodiment will be described below. First, the roller motor 52 of the coin moving unit 50 rotates, and the front and back surface rollers 51 rotate. Then, the coin 10 whose upper surface is brought into contact with the front and back surface roller 51 moves on the front and back surface support portion 20 in accordance with the rotation direction of the front and back surface roller 51. At the same time, in the coin 10, the biasing plate member 41 of the biasing portion 40 protruding from the through hole 22 receives the biasing force of the biasing spring 42 on its circumferential surface, and is pressed against the thickness measuring scale 30 side. The part contacts the slope 31.

When the moving coin is smaller than the diameter of the proper coin, the illegal coin 11 is disengaged from the mounting edge 21A of the diameter measuring scale 21, so that the coin 10 is dropped from the drop hole 29. Although illustration is omitted, when the moving coin is thicker than the proper coin, a part of the upper surface of the illegal coin comes into contact with the slant portion 31 of the thickness measuring scale 30, but the lower surface of the illegal coin is placed on the mounting surface of the thickness measuring scale 30. Since the coin is removed from the setting edge 30A, the coin drops from the drop hole 29.

When the moving coin has the same diameter as the proper coin and is thin, a part of the upper surface of the illegal coin comes into contact with the slant portion 31 of the thickness measuring scale 30 and the lower surface thereof is also supported. The lower surface of the coin 10 on the opposite side of the thickness measuring scale 30 is pushed by the force portion 40 and moved toward the vertical portion of the thickness measuring scale 30, and the diameter measuring scale 2
Since the coin 10 comes off from the placing edge 21A of No. 1, the coin 10 falls through the drop hole 29.

Incidentally, a coin having a diameter larger than the diameter of the proper coin does not enter the size of the coin insertion slot of the device to which the coin sorter of this embodiment is attached and is eliminated before the insertion. Thus, only the coin 10 having the same diameter and thickness as the proper coin can pass through the coin sorter of this embodiment. Next, the effect of this embodiment will be described.

According to the present embodiment, the passing efficiency of the coins 10 can be improved by forcing the coins 10 to pass when the coins 10 are selected. Further, as is clear from comparison of FIG. 3 with FIG. 6, the coin moving path formed by the diameter measuring scale 21 and the thickness measuring scale 30 can be shortened, and the coins that reduce design restrictions can be reduced. We were able to provide a sorter.

Next, an embodiment of a coin sorter corresponding to the invention of claim 2 will be described. The coin sorter of this embodiment also has a front and back surface support portion 20 that supports the lower surfaces of the front and back surfaces of the coin 10, a biasing portion 40 that biases the coin 10 downward, and the front and back surface support portion 20 thereof. 10 coins along
And a coin moving unit 60 for moving the coin. That is, the coins 10 are horizontally moved and selected. The invention according to claim 2 is not limited to the one in which the coins are horizontally moved and selected as described above, and for example, the coins may be moved vertically.

The front and back surface supporting portion 20 is a diameter measuring scale 2
1 and a thickness measuring scale 30. The diameter measuring scale 21 is almost the same as the diameter measuring scale of the coin sorter of the above-described embodiment, except that a through hole is provided for the biasing portion.

The thickness measuring scale 30 is also a member having a substantially U-shaped vertical cross section, and is similar to the above-described embodiment. Furthermore, the same applies to the drop hole 29 formed by the diameter measuring scale 21 and the thickness measuring scale 30. Both sides of the drop hole 29 serve as mounting edges, which are parallel to the coin moving direction of the coin moving unit 50. Diameter measurement scale 2
The thickness measurement scale 30 side end of the bottom of 1 is placed edge 21
A, diameter measurement scale 2 at the bottom of the thickness measurement scale 30
The one side end is referred to as a mounting edge 30A.

The urging portion 40 is composed of an urging plate member 41 and an urging spring 42 for urging the urging plate member 41. The urging plate member 41 is located above the drop hole 29 and the front and back surfaces of the coin 10 are located. Touch the top surface of. The coin moving unit 60 includes a circumferential surface roller 61 having a circular horizontal cross section, and a roller motor (not shown) for rotationally driving the circumferential surface roller 61. The circumferential surface roller 61 is brought into contact with the upper surface of the circumferential surface of the coin 10 to rotate and move the coin.

The material forming the surface of the circumferential surface roller 61 is preferably rubber or the like, which has a certain degree of elasticity and hardness, like the front and back surface roller 51. Since coins are hard,
If the surface of the circumferential surface roller 61 is hard, it is not familiar with coins and it becomes difficult to transfer the coins.
If the surface is too soft, coins thicker than the proper diameter and thicker will pass without being sorted.

Further, in order to cope with the change in the thickness of coins, the entire circumferential surface roller 61 may be vertically movable. The operation of the above embodiment will be described below. First, the roller motor of the coin moving unit 60 rotates and the circumferential surface roller 61 rotates. Then, the coin 10 with a part of its peripheral surface contacting the circumferential surface roller 61 is pressed against the thickness measuring scale 30 side by the rotation of the circumferential surface roller 61, and a part of the coin 10 contacts the slant portion 31. At the same time, the front and back surface supporting portion 20 is moved. At the same time, the coin 10 is pressed downward by the urging plate member 41 of the urging portion 40 receiving the urging force of the urging spring 42 on its front and back surfaces.

When the moving coin is smaller than the diameter of the proper coin, the illegal coin 11 is disengaged from the diameter measuring scale 21, so that the coin 10 drops from the drop hole 29. Although illustration is omitted, when the moving coin is thicker than the thickness of the proper coin, a part of the upper surface of the illegal coin comes into contact with the slant portion 31 of the thickness measuring scale 30, but the lower surface thereof comes off the thickness measuring scale. , The coin drops from the drop hole 29.

When the moving coin has the same diameter as the proper coin and a small thickness, a part of the upper surface of the illegal coin comes into contact with the slant portion 31 of the thickness measuring scale 30 and the lower surface thereof is also supported. The lower surface of the coin 10 on the opposite side of the thickness measuring scale 30 is pushed by the force portion 40 and moved toward the vertical portion of the thickness measuring scale 30, and the diameter measuring scale 2
Since the coin 10 is removed from the coin 1, the coin 10 drops from the drop hole 29.

Incidentally, a coin having a diameter larger than the diameter of the proper coin does not enter the size of the coin insertion slot of the device equipped with the coin sorter of this embodiment, and is eliminated before the insertion. Thus, only the coin 10 having the same diameter and thickness as the proper coin can pass through the coin sorter of this embodiment. Next, the effect of this embodiment will be described.

According to this embodiment, the passing efficiency of the coins 10 can be improved by forcing the coins 10 to pass through when the coins 10 are sorted. Further, the passage through which coins formed by the diameter measurement scale 21 and the thickness measurement scale 30 move can be shortened, and it is possible to provide a coin sorter that reduces design restrictions. In particular, compared with the coin sorter described as the embodiment corresponding to the invention of claim 1, in the coin sorter of the present embodiment, the circumferential surface roller 61 as the coin moving unit 60 is located on the peripheral surface of the coin. Since they are brought into contact with each other, the thickness of the entire coin sorter can be designed small.

Next, variations of this embodiment will be described. Although the urging portion 40 of the above-described embodiment is described as a combination of the spring and the pressing plate, the present invention is not limited to this. For example, by tilting the front and back surface supporting portion 20 downward toward the thickness measuring scale 30, it is possible to urge the coin 10 using its own weight.
