Description

Detailed Description of the Invention [Objective of the Invention] (Industrial Field of Application) The present invention provides a rotating cam for moving a coin processing member in a direction in which it comes into contact with a coin, and a cam follower that comes into contact with the rotating cam. A coin processing machine having a lever that is attached and pivoted about a fixed fulcrum shaft through the cam follower when the rotating cam rotates, and that moves the coin processing member in a direction in which it comes into contact with coins based on the pivoting motion. The present invention relates to a safety device such as a lever that ensures the safety of a lever and a coin processing member when a hardening processing member that is moving in the direction of contacting a coin by a rotating cam comes into contact with a coin and stops.

(Prior art) Coin counting machines, coin sorting machines, coin wrapping machines, etc. that automatically process coins (processing here refers to coin counting, coin wrapping, etc.)
A coin processing machine that performs processing such as coin sorting and coin packaging (hereinafter collectively referred to as coin processing) has a coin processing member. For example, a coin counting machine or a coin sorting machine has coin processing members such as a coin floating prevention plate in a coin counting or sorting passage, a conveyor belt pulley, a conveyor roller, and a passage width constituent member that determines the passage width. In addition to the above, the packaging machine also adjusts and/or adjusts the barrel diameter components of the coin diameter adjusting barrel device, crimping claws, packaging rollers, support rods that support and guide stacked coins from the barrel device to between the packaging rollers, etc. It must be moved for processing operations. Movement of these coin handling members is often performed by a rotating cam and a lever operated by the rotating cam.

(Problems to be Solved by the Invention) By the way, when the coin processing member is moved using a rotary cam and a lever, among others,
A rotating cam for moving the coin processing member in the direction of contacting the coins and a cam follower that comes into contact with the rotating cam are attached, and when the rotating cam rotates, the rotating cam swings about a fixed fulcrum shaft through the cam follower, and this swinging In the case of a coin processing machine that is equipped with a lever that moves the coin processing member in the direction of contacting the coin based on the above, and that moves the coin processing member directly or indirectly through a transmission lever, etc., the following shall be applied. There's a problem. In other words, when the lever is operated by a rotary cam to move the coin handling member, a coin, such as a coin that remains without being ejected, is used to move the coin handling member and the lever. If a transmission lever or the like is interposed on the driven side, the transmission lever or the like may be prevented from moving. On the other hand, since the drive side of the lever driven by the rotary cam is forcibly operated by the rotary cam, the first drawback is that the lever and the hardening treatment member etc. may be broken or distorted. The second drawback is that once such an accident occurs, it is not easy to repair and it is time consuming.

In addition, in a coin processing machine, multiple coin processing members are used to perform a single coin processing function (e.g. passage width constituent members, transfer belts and pulleys, coin floating prevention plate, etc.) for coin counting processing. In many cases, stacked coins are pinched and rotated for coin packaging processing by moving the support rod in the coin radial direction and coin thickness direction, and by moving the packaging roller in the radial direction. Alternatively, the coin processing must be moved in conjunction with each other for the coin processing operation, and therefore a large number of rotating cams for moving each coin processing member are provided on a camshaft rotated by a motor, and each of the corresponding rotating cams is selected from a group of rotating cams. The movement is transmitted to the coin handling member by a lever or a sliding transmission member that slides.

In order to move such a coin processing machine, especially various coin processing members in a direction where they come into contact with coins,
A group of rotating cams are provided with each coin processing member corresponding to a camshaft rotated by a motor, and a cam follower is attached that comes into contact with one of the rotating cams in the group of rotating cams. For example, in a coin processing machine equipped with a lever that swings around a fixed fulcrum shaft and moves a hardening member corresponding to the rotating cam in a direction in which it comes into contact with coins based on the swing movement, If there are any coins left behind, the coins will prevent the movement of multiple coin processing members that perform a single coin processing function, and these coin processing members, Damage to the lever, sliding transmission member, rotating cam, etc.
The third drawback is that it can cause bending, damage, etc., and that repairs must be made at multiple locations. , there is a fourth drawback that it is often impossible to repair.

[Structure of the invention]

(Means for Solving the Problems) The first invention of the present application solves the first and second drawbacks of the prior art, in which a cam follower is attached and operated by the rotating cam. It has a structure divided into a driving side lever part and a driven side lever part that follows this driving side lever part, and the lever swings around a fulcrum shaft, and the driving side lever and driven side lever can be bent. a pivot pin pivotally attached to the rotary cam, and a direction in which the drive-side lever portion can be moved by the rotary cam even if the coin handling member that is being moved in the direction of contacting the coin by the rotary cam comes into contact with the coin and stops. A stopper portion is formed on both lever portions to allow both lever portions to be bent freely around the pivot pin and to restrict the bending direction at a predetermined position, and a stopper portion is formed on both lever portions to allow coin processing without being affected by coins. The present invention includes a spring that maintains the respective stopper portions of both lever portions in contact with each other when the member is moved, and causes both lever portions to integrally swing around the fulcrum shaft by the rotating cam.

Furthermore, the second invention of the present application is aimed at solving the third and fourth drawbacks of the prior art, but it is provided that the safety device such as the lever of the first invention is attached to each lever. We focused on the fifth drawback that if applied, the number of parts would increase and the assembly work would be complicated, and it would be difficult to apply it to coin handling members that use a sliding transmission member that slides.
This problem is solved by a structure that is divided into a drive side lever part to which a cam follower is attached and is operated by the rotating cam, and a driven side lever part that is driven by this drive side lever part, and is centered around a fulcrum shaft. a lever that is pivoted to the side; a pivot pin that pivotably connects the drive side lever portion and the driven side lever portion; Both lever parts can be bent around the pivot pin in a direction that allows the drive side lever part to be moved by the rotary cam even when the lever part comes into contact with and stops. When the coin processing member is moved without being affected by coins, the stopper parts formed on both lever parts are kept in contact with each other, and the rotating cam causes the stopper parts formed on both lever parts to be in contact with each other. a spring that integrally swings the motor around a fulcrum shaft; and a spring that is provided on either the drive-side lever section or the driven-side lever section, and detects bending between both lever sections and stops the motor. The present invention is provided with a switch and a switch actuating section which is provided on the other side and switches the switch when the two lever sections are bent.

Both lever parts are bent around the pivot pin in the direction in which the stopper part of the lever part is separated, and through this bending, the drive side lever part rotates relative to the driven side lever part whose movement is stopped by the coin handling member. Movement is possible using a cam.

Further, in the second invention, when the coin processing member is swung without being influenced by coins, the spring holds each stopper part of both lever parts in a contact state, and through this holding, the rotating cam The coin handling member is moved by swinging both lever parts together around the fulcrum shaft, and when the coin handling member comes into contact with a coin and stops, both lever parts move against the bias of the spring. Both lever parts are bent around the pivot pin in the direction in which the stopper part is separated, and through this bending, the drive side lever part is stopped from moving by the coin processing member, and the drive side lever part is rotated by the rotating cam. When the camshaft is bent, the switch is activated to stop the motor and stop the rotation of the camshaft.

(Embodiment) Hereinafter, a case where an embodiment of the safety device such as a lever according to the present invention is applied to a coin counting machine will be described.

A rotating disk 2 rotated by a drive motor (not shown) is provided on the machine base 1 of the coin counting machine A so as to be rotatable in the direction of the arrow in a horizontal plane, and outward from the periphery of the rotating disk 2. A coin passage 3 is extended. A coin is thrown onto this rotating disk 2, and due to the rotation of the rotating disk 2, the coin C is
The coin is moved in the direction of its periphery, moved along the guide edge 5 of a coin guide rail 4 attached near the periphery of the rotating disk 2 and communicating with the coin passage 3, and fed into the coin passage 3.

The coin passage 3 includes a coin guide plate 6 which swingably connects the coin guide rail 4 with a connecting piece 4', and which guides the edge of the fed coin, and which guides the other edge of the coin. fixed to the other coin guide plate 6a and the lower surface of each of the coin guide plates 6, 6a,
It is composed of coin sorting plates 7, 7a forming a removal port E as a sorting groove for removing coins of a smaller denomination to be processed.

The coin guide plate 6 and the coin sorting plate 7 are the members that constitute one passage width, and the coin guide plate 6a and the coin sorter plate 7a are the members that constitute the other passage width, and each coin is used for coin sorting and counting. It is a processing member.
On the downstream side of the coin passage 3, a star-shaped counting wheel 8 is provided which engages with the edge of a coin passing through the coin passage 3 and rotates by a predetermined angle. The coin guide plates 6, 6a are fixed to movable base plates 10, 10a which can be adjusted and moved according to the diameter of the denomination coins to be processed, and the above-mentioned coin sorting plate is attached to the movable base plates 10, 10a. 7, 7a are also provided, and the movable base plate 1

11a.

At a position above the coin passage 3, a coin processing device is provided which presses into contact with the upper surface of a coin fed into the coin passage 3 along the coin guide rail 4, forcibly moves the coin, and discharges the coin into the discharge port 12. A scraping belt 13 as one of the members is attached to a pair of pulleys 1
4, 14a. This pulley 1
4 and 14a are supported by a support frame 15, and the shaft 16 of one pulley 14a is connected to a drive motor (not shown). The shaft 17 of the other pulley 14 is rotatably supported by the support frame 15.

Further, the coins located above the coin passageway 3 and close to the scraping belt 13 and forcibly moved by the scraping belt 13 over almost the entire length of the coin passageway 3 are prevented from floating up. A coin floating prevention plate 18 is provided as one of the coin processing members.

This coin flotation prevention plate 18 (which also serves as a detection member for detecting the presence or absence of residual coins for the safety of levers, etc. to be described later) is connected to the coin sorting plate 7,
The distance between the top surface of the coin 7a and the top surface of the coin 7a can be adjusted in the vertical direction according to the thickness of the coin to be processed, and this adjustment is made by a mechanism shown in FIG.

That is, this mechanism transmits the amount of lift by the cam 37, which is one of the rotary cams, to the support plate 19 that swings around the fulcrum shaft 20 via a lever as an example of a lever in the present invention. 19
The coin floating prevention plate 18 fixed to the tip of the coin float can be adjusted in the vertical direction with respect to the coin passage,
In particular, this lever is divided into a second arm 29 as a driving lever section operated by a rotating cam 37 and a first arm 25 as a driven lever section.

More specifically, the coin floating prevention plate 18 is fixed to a support plate 19 provided below the support frame 15, and this support frame 15 and the support plate 19

An adjustment screw 21 is screwed into this support frame 15 in order to adjust the distance between the support plate 19 and the support frame 15, while a lower end of the support frame 15 is connected to a suspension pin 22 fitted with the support plate 19 to adjust the distance between the support frame 15 and the support plate 19. A compression spring 23 is inserted through the screw 21 to keep it in contact with the lower end of the screw 21. This is because the pulley 1 is aligned with the support plate 19 and the coin floating prevention plate 18, which are adjusted and held at a fixed position when the coin passes under the scraping belt 13 of the pulleys 14, 14a.
4, 14a and the support frame 15 are integrally floated according to the thickness of the coin. One end on the opposite side of the support plate 19 is fixed to the upper surface of a bracket 24, and a first arm 25 is fixed to the lower part of the bracket 24 as a driven side lever portion of the lever.

The first arm 25 has a hook-shaped tip, and is pivotally connected at its intermediate point by a pivot pin 27 so as to overlap with a second arm 29 serving as a drive-side lever portion of the lever. An adjustment screw 30 as a stopper is interposed between the hooked end portion 25a of the arm 25 and the knee portion 29a of the second arm 29, and both arms 25, 29 are pulled by a tension spring 32, so that the two arms The bending state in only one direction is possible.

On the other hand, a cam follower 33 is attached to the other end of the second arm 29, and this cam follower 33 engages with a cam 37, which corresponds to the rotating cam of the present invention, and is adapted to be displaced in the vertical direction.

This cam 37 is for height adjustment and is fixed to a denomination selection shaft 36 which is a cam shaft, and this shaft 36 is a denomination selection drive that is driven when changing the coin denomination to be processed. It is designed to be driven by a motor 34 via a pair of gears 35, 35.

Therefore, the cam 37 is rotated by the motor 34 and the cam follower 33 that engages with the cam 37 allows the second arm 29 and the first arm 25 as levers to be integrally moved while maintaining a predetermined positional relationship by the adjusting screw 30 and the tension spring 32. It is swung around the fulcrum shaft 20, and the coin floating prevention plate 18 is vertically adjusted with respect to the coin passage. However, if there are remaining coins in the coin passage, the remaining coins will prevent the coin floating prevention plate 18 from moving downward, and as a result, the first
The arm 25 also stops swinging, while the second arm follows the cam 37 and swings around the pivot pin 27 which is pivotally connected to the first arm 25, so that the tension between the two arms 25 and 29 is reduced. It is bent against the spring 32. As a result, the coin floating prevention plate 18, the arms 25, 29, and the cam 37 are prevented from being damaged or broken, and the safety of the lever and the like is ensured. In this example, consideration is also given to preventing the coin guide plates 6, 6a, coin sorting plates 7, 7a, passage width adjustment cams 39, 40 (described later), etc. from being damaged by residual coins.
A detection switch 26 is provided on the abdomen of the first arm 25 to detect when the first arm 25 and the second arm 29 are bent. Therefore, this switch 26 is
The actuating edge 28 of the second arm 29, which serves as the switch actuating portion of the present invention, is pressed when the bending occurs. If the bending is detected by the switch 26, the motor 3
It is designed to stop the rotation of 4.

In addition, in order to detect residual coins in the coin passageway that may cause the bending, the coin floating prevention plate 18 is actively lowered into the coin passageway 3 before being adjusted and moved to a height position according to the denomination. ing.
Therefore, the height adjusting cam 37 is different from a known height adjusting cam that has only a height adjusting cam surface, and as shown in FIG. Recesses 38a serving as height adjustment cam surfaces are formed at equal intervals, and the distances vary depending on the thickness of the coins to be processed. Furthermore, there is a protruding cam surface 3 between the recesses 38a, 38a.
8b, the distance from the axial center of the cam 37 to the protruding cam surface 38b is equal, and the dimensions are such that the coin floating prevention plate 18 is lowered to the upper surface position of the coin sorting plates 7 and 7a.

〔Effect of the invention〕

As explained above, according to the first aspect of the present invention, a rotary cam for moving the coin processing member in a direction in which it comes into contact with coins, and a cam follower that comes into contact with the rotary cam are attached. In a coin processing machine that is equipped with a lever that swings about a fixed fulcrum shaft through a cam follower during rotation, and moves the coin processing member in a direction in which it comes into contact with the coin based on this swing, the coin processing member contacts the coin processing member. Even if the movement of the driven side lever portion of the lever is blocked due to the movement of the coin handling member being blocked by coins, such as residual coins, the safety of the lever can be ensured.

According to the second invention, a group of rotating cams are provided on a camshaft that is rotated by a motor in order to move the various coin processing members in a direction in which they come into contact with the coins, corresponding to each coin processing member. A cam follower is attached to contact one of the rotating cams in the group of rotating cams, and when the rotating cam rotates, the cam follower is swung around a fixed fulcrum shaft through the cam follower, and based on this oscillation, the cam follows the cam. In a coin processing machine equipped with a lever that moves the coin processing member in a direction in which it comes into contact with the coin, the movement of the coin processing member is blocked by coins that come into contact with the coin processing member, such as residual coins. In addition to the above-mentioned effect of ensuring the safety of the lever even if the movement of the driven side lever portion of the lever is blocked, this also has the excellent effect of ensuring the safety of other coin handling members and the like.
