Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to coin handling machines such as coin counting machines, coin sorting machines, and coin dispensing machines. The present invention relates to a coin thickness regulating device for layering coins in the thickness direction and feeding them one by one to a coin passage.

[Conventional technology]

Generally, a coin processing machine using a rotating disk has a fifth
As shown in the figure and FIG. 6, the processed coins C supplied onto the rotating disk 1 are moved to the peripheral edge 2 by the centrifugal force caused by the rotation of the rotating disk 1, and are removed from the peripheral edge 2 of the rotating disk 1. While the coins C are being sent on the coin passage 3, necessary processing such as counting and identification is performed, and then the coins are sent to a sorting section and a dispensing section. It is starting to be sent.

In such a coin processing machine, the coin passage 3
A coin thickness regulating device 4 is provided above a portion where the rotary disk 1 and the coin passage 3 are connected to each other so that two coins C are not sent out in a pile.

This coin thickness regulating device 4 conventionally has a rotating disk 1.
A thickness regulating member 5 is provided between the rotating disk 1 and the peripheral edge 2 at a fixed position with an interval that allows only one processed coin C to pass therethrough.

The thickness regulating member 5 allows the lowest layer of coins C among the coins C moving in an overlapping state along the peripheral edge 2 of the rotating disk 1 to pass through the lower part of the thickness regulating member 5 and enter the coin passage 3. The coins C of the second and higher layers are moved along the regulating edge 6 of the thickness regulating member 5 and are regulated so as not to enter the coin passage 3.

[Problem that the invention attempts to solve]

The coins supplied onto the rotating disk are moved to the periphery of the rotating disk by the centrifugal force caused by the rotation of the rotating disk, and after moving along the periphery of the rotating disk, the coins are overlapped by the thickness regulating member. Only the coins in the lowest layer of the stack are fed into the coin passage, and the coins in the second and higher layers are moved toward the center of the rotating disk along the regulating edge of the thickness regulating member. Depending on the degree of overlapping, a portion of the upper coin of the stacked coins may enter under the thickness regulating member, and the lower coin may also try to enter under that coin, causing rotational interference with the thickness regulating member. Coins get caught between the disc and the disc.

If the coin was only slightly caught in the coin, the rotating disc would be reversed to eliminate the jam, but if the coin was severely stuck, the rotating disc would be locked. There were cases where it became impossible to rotate forward or reverse.

In such a case, stop the rotation of the rotating disc, release the fixed position of the thickness regulating member, open the gap between the thickness regulating member and the rotating disc, and remove the stuck coins. , the thickness regulating member must be fixed in its original regulating position again.
It was very inconvenient to remove the stuck coin and reset the device.

In order to eliminate the above-mentioned inconvenience, we have considered a movable thickness regulating device in which the thickness regulating member is shaped like a leaf spring so that it can be bent only toward the center of the rotating disk, and one in which the thickness regulating member is bent only toward the center of the rotating disk. It is conceivable that the position is supported by an axis parallel to the rotating disk and can only swing toward the center of the rotating disk, but in both cases, as the thickness regulating member moves toward the center, it also always moves upward. Because it moved and was moving unregulated, there was a problem in that when the rotating disk was reversed to eliminate the jam, secondary jams such as those caused by coins getting caught occurred.

The present invention was developed in view of the above-mentioned points, and it is possible to easily and reliably eliminate the coin jamming between the rotating disk and the thickness regulating member, and also to prevent the secondary coin jamming that occurs while the coin is being jammed. It is an object of the present invention to provide a coin thickness regulating device in a coin processing machine that can prevent the above problems.

[Means for solving problems]

In the present invention, the centrifugal force of the rotating disk 11 moves the coins on the rotating disk 11 to the periphery, and the thickness is set at a height that allows only one coin to pass through the top of the periphery of the rotating disk 11. In a coin processing machine in which coins are made into a single layer in the thickness direction by a regulating member 18 and sent from a rotating disk 11 to a coin passage 17 and subjected to necessary processing such as counting, identification, or sorting, one side near the entrance of the coin passage 17 is used. a swing shaft 32 that is vertically installed to support the thickness regulating member 18 horizontally and allow it to slide slightly in the vertical direction; The rotating disk 11 of the thickness regulating member 18 when sending out coins due to forward rotation of the rotating disk 11
an outer swing regulating section 3 that regulates the outward swing movement of the
3, and an inner swing regulating portion 34 for regulating the swinging movement of the thickness regulating member 18 inward of the rotating disc 11 when the rotating disc 11 is reversed to eliminate coin jamming.
The thickness regulating member restricts the downward sliding movement of the thickness regulating member 18 and extends over the entire swing range regulated by the outer swing regulating portion 33 and the inner swing regulating portion 34 to the rotating disk 11. 18 to a fixed lower limit position slightly higher than the thickness of one coin to be processed; When the swinging position of the member 18 is regulated by the outer swinging restriction part 33, the sliding position is regulated to the certain lower limit position where it cannot move up or down in cooperation with the lower swinging restriction part 36. However, when the thickness regulating member 18 swings in the inward direction, the upper sliding member is configured such that the upper limit of the height of the thickness regulating member 18 relative to the rotary disk 11 is restricted to a range lower than the thickness of two processed coins so that it can move upwardly. The thickness regulating member regulating means 31 includes a regulating portion 35.

(Function) In the present invention, as the rotating disk 11 rotates forward, the thickness regulating member 18 is pushed by the coin rotating on the rotating disk 11 and swings outward of the rotating disk 11 about the swing shaft 32. be done. Due to this outward swinging of the thickness regulating member 18, the lower limit of the height of the thickness regulating member 18 relative to the rotating disk 11 is set to a thickness equal to one coin by the upper sliding regulating portion 35 and the lower sliding regulating portion 36. It is supported so as not to move up and down at a fixed lower limit position slightly higher than the height. In this state, only the lowest layer of coins that are moved in an overlapping manner on the rotating disk 11 is removed by the thickness regulating member 18.
It is sent out passing under the

In addition, if a coin is caught between the thickness regulating member 18 and the rotating disk 11, the rotating disk 11
Reverse. Due to this reversal of the rotating disk 11,
The thickness regulating member 18 swings inward from the center of the rotary disk 11 about the swing shaft 32 together with the bitten coin. When the thickness regulating member 18 moves inward, the upper sliding regulating portion 35 allows the thickness regulating member 18 to move upward, thereby eliminating the coin jamming. At this time, the thickness regulating member 1
8 is regulated within a range where the upper limit of the height of the thickness regulating member 18 with respect to the rotating disk 11 is lower than the thickness of two coins, and only one coin can enter under the thickness regulating member 18. , secondary coin entrapment is prevented during coin entrapment release.

In addition, at the connecting portion between the base 20 and the regulating edge 21, that is, on the lower surface of the terminal end of the regulating edge 21, there is a branching roller 22 that branches the coins C that enter under the regulating edge 21 and the coins C that do not enter. It is rotatably supported.

Further, a regulating portion 23 that constitutes a part of a thickness regulating member regulating means 31 (to be described later) is integrally provided at the tip of the regulating edge 21 that protrudes outward from the rotary disk 11, and this regulating portion 23 extends horizontally. It is formed in a substantially U-shape with a regulation groove 24 that opens along. Further, a regulating roller 26 is rotatably supported by a substantially L-shaped support member 25 on the chassis S of the coin processing machine facing outside of the regulating section 23 . It fits into the regulation groove 24 and rotates and moves within the regulation groove 24 as the regulation part 23 moves in the horizontal direction.

The thickness regulating member 18 is a thickness regulating member regulating means 31

The swing shaft 32 has a head 32a at the upper end, and the base 20 of the thickness regulating member 18 can slide vertically by the distance between the head 32a and the upper surface of the thickness regulating member 18.

The outer swing regulating section 33 is configured by the outer regulating surface 24a of the inner surface of the regulating groove 24 coming into contact with the regulating roller 26 based on the outward movement of the regulating section 23.

The inner swing regulating section 34 is configured to rotate the rotating disk 1 of the regulating section 23 based on the movement of the regulating section 23 inward.
The inner regulating surface 23a on the side facing the disk peripheral wall 15

is forcibly delivered to the coin passage 17.

A conveyor belt 43 is stretched over the coin passage 17 by a pulley 42, and this conveyor belt 43
receives the coin C fed out by the feeding roller 41, presses it into the coin passage 17, and conveys it. Note that the conveyance speed of the coin C on this conveyor belt 43 is as follows:
It is set to be faster than the circumferential speed of the delivery roller 41, and has the effect of creating an appropriate interval between the coins C being conveyed through the coin passage 17. This is coin passage 1
7, the coins C are counted and identified or sorted, so if the coins C are continuously fed out, it would be inconvenient.

Also, along both sides of the coin passage 17, the coin passage 1
Guide plates 44, 44 are provided to guide both sides of the coin C being conveyed on the coin C.

Next, the operation of this embodiment will be explained.

By rotating the rotating disk 11 in the forward rotation direction a,
The plurality of processed coins C supplied onto the rotating disk 11 are moved by centrifugal force to the peripheral edge 11a, and are moved along the disk peripheral wall 15 in the forward rotation direction a.

One coin C moved along the disk peripheral wall 15
The coins C are sent out to the coin passage 17 through the lower part of the thickness regulating member 18, and the coins C that are moved in an overlapping state are the coins C in the lowest layer among the coins C.
Only the coins C pass through the lower part of the thickness regulating member 18 and are sent out to the coin passage 17, and the coins C in the second and higher layers move along the regulating edge 21 of the thickness regulating member 18 and are returned onto the rotating disk 11. .

The coin C fed into the coin passage 17 is fed out into the coin passage 17 by the feeding roller 41, and the coin C fed out by the conveyor belt 43
The coins are received and conveyed along the coin path 17, and required processing such as counting, identification, or sorting is performed.

Further, when the coin C is being fed into the coin passage 17, the thickness regulating member 18 is pushed by the coin C rotating on the rotating disk 11, as shown in the solid line state in FIG. 2 and in FIG. The regulating portion 23 side is swung outward about the swing shaft 32, and the outer regulating surface 24a of the regulating portion 23 is aligned with the regulating roller 26.
At the same time, the lower and upper regulating surfaces 24b of the regulating portion 23 are in contact with the upper and lower parts of the regulating roller 26,
24c is in contact with the rotary disk 11 so that the lower limit of the height of the regulating edge 21 of the thickness regulating member 18 relative to the rotating disk 11 is in a regulating support state at a fixed lower limit position slightly higher than the thickness of the coin C, and the base of the thickness regulating member 18 2
The zero side is in a state of sliding downward with respect to the swing shaft 32 due to its own weight. In this state, only the lowest layer of coins C of the coins C moved in an overlapping manner on the rotating disk 11 passes through the lower part of the regulating edge 21 and is delivered to the coin passage 17.

Further, when a coin C is caught between the thickness regulating member 18 and the rotating disk 11, a part of the upper coin C of the overlapping coins C may be caused by the regulating edge 21 depending on the degree of overlapping of the coins C, for example. When the lower coin C enters the lower part and the lower coin C further enters under the coin C to cause jamming, the rotating disk 11 is rotated in the reverse rotation direction b.

By rotating the rotating disk 11 in the opposite direction, the thickness regulating member 18 rotates around the swing shaft 32 together with the bitten coin C as the rotating disk 11 rotates, as shown in the imaginary line state in FIG. 2 and in FIG. 4. Disc 11
Swings inward from the center.

Due to this inward swinging of the thickness regulating member 18, the contact with the lower part of the regulating roller 26 shifts from the upper regulating surface 24c to the inclined surface 24d, and the regulating portion 2
3 is allowed to move upward, and the base 2
0 is slightly allowed to slide upwardly along the swing axis 32, and therefore upward movement of the regulating edge 21 is allowed. Even if the coin C is strongly bitten in the machine, the biting of the coin C is eliminated.

The upward movement of the regulating edge 21 is regulated by the contact between the regulating roller 26 and the inclined surface 24d, and the regulating edge 21 is kept at a height that allows only one coin to pass through. Therefore, the coin C is prevented from being caught during this jamming release. Further, the inward rocking of the thickness regulating member 18 is controlled by the regulating portion 2.
The inner regulating surface 23a of No. 3 comes into contact with the disc peripheral wall 15 and is regulated.

In addition, after the coin C is released, the rotating disk 1
1 in the forward rotation direction a, the thickness regulating member 18 is pushed by the coin C on the rotary disk 11, and the regulating part 23 side is swung outward, so that the outer regulating surface 24a, the upper side and the upper side of the regulating part 23 are rotated. The lower regulating surfaces 24c and 24b abut against the regulating roller 26,
The lower limit of the height of the regulating edge 21 of the thickness regulating member 18 with respect to the rotating disk 11 is regulated and supported at a fixed lower limit position slightly higher than the thickness of the coin C, and the coin C on the rotating disk 11 is controlled by the thickness regulating member 18 into the coin path. 17, one sheet at a time.

In the above embodiment, the thickness regulating member 18 was provided to be slidable in the vertical direction with respect to the swing shaft 32, but the swing shaft 32 is fixed to the thickness regulating member 18, and the swing shaft 32 is fixed to the thickness regulating member 18. may be supported so as to be slidable in the vertical direction with respect to a chassis on the side of the coin passage 17.

[Effect of idea]

According to the present invention, the thickness regulating member is supported so as to be horizontally swingable by the swing shaft, and is also supported to be vertically slidable, and when the rotating disk rotates forward, it is pushed by a coin and swings outward of the rotating disk. The vertical movement of the moving thickness regulating member is regulated to ensure that coins are sent out one by one, and when a coin is bitten, the rotating disk is reversed so that the coin is swung inward along with the bitten coin. In order to allow the upward movement of the thickness regulating member, even if a coin is strongly caught between the rotating disc and the thickness regulating member and the rotating disc is locked, the coin jamming can be automatically resolved. This eliminates the inconvenient work of stopping the drive of the rotating disk and opening the thickness regulating member to remove stuck coins as in the past.
Furthermore, since the upward movement of the thickness regulating member is within the range in which coins can be restricted one by one with respect to the rotating disk, secondary coin entrapment can be prevented during coin entrapment release.
