Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a coin width sorting device in a coin processing machine. This type of coin processing machine has the function of sorting the same type of coins from a mixture of coins and counting them at the same time.This sorting of coins mainly involves measuring the thickness and diameter of the coins. In particular, this sorting device introduces coins into a measurement course of a predetermined width by pressing each coin from above with a belt, and while the coins are traveling in the measurement course, a coin ejector installed at the bottom of the measurement course is used. The present invention relates to a sorting device that allows only small-diameter coins to fall and be ejected from an outlet, and that mainly uses coin width as a measurement standard.

(Prior Art) Conventionally, coins are sorted by coin width by pressing from above a belt disposed along a course with a groove width that approximately matches the width of the target type of coin. Only coins with the same width as the course width or less than the course width are introduced, and coins with larger widths are blocked and sorted before being introduced into the course. Furthermore, among the coins introduced into the course, coins with a diameter smaller than a predetermined diameter fall through a discharge port opened at the bottom of the course groove, enter a dissimilar coin receptacle, and are sorted and ejected. Setting a measurement course with a predetermined width to match the coin diameter is carried out by adjusting the interval between a pair of course fixed plates and a movable course plate, but the lower edge of the pair of fixed plates and movable plate forming the course Inward receiving rails extend respectively, and the coins that match the measurement course width are supported by this pair of receiving rails, move within the course, and are collected at a predetermined location for the intended sorting operation. It can be achieved.

Among the coins introduced into the course, small-diameter coins are cantilevered by one receiving rail as they move along the inner edge of one of the pair of course-forming plates. The coin moved and fell from the outlet in a very natural manner, but by chance this small-diameter coin was slightly supported between a pair of receiving rails.
Although it is rare, there are cases where coins are momentarily driven around the course at high speed and are sorted and counted along with large-diameter coins.

As one means for solving this situation, there is, for example, Japanese Utility Model Publication No. 56-20857. In the same bulletin,
An endless cogged belt is used for introducing coins into the measurement course, and the outer peripheral surface of the endless belt is located on at least one side of a small-diameter toothed pressure roller that is driven by meshing with the inner teeth of the cogged endless belt. A large-diameter toothed press roller with external teeth formed with a larger diameter is also installed so as to protrude by a predetermined amount than the above, and this large-diameter press roller is placed above the small-diameter coin ejection port opened at the bottom of the measurement course. A sorting device with a structure arranged in is disclosed, and as the cogged belt runs,
The small-diameter press roller that meshes with and rotates immediately causes the large-diameter press roller to rotate, thereby bringing the top surface of the small-diameter coin that is about to pass over the ejection port into contact with the outer teeth of the large-diameter press roller, This is intended to fall through the outlet.

(Problem to be solved by the invention) A small-diameter toothed pressure roller that meshes with the cog part of the cogged belt, and a large-diameter external tooth on the side of the roller that comes into contact with the top surface of the moving coin. Utility Model 56-20857 whose basic structure is a pressure roller
The feeding device of the coin processing machine disclosed in the publication has a strong force for pressing the coin from above, but the double-toothed pressing roller meshes with the cog portion of the running endless cog-equipped belt. Due to the relationship, there is a limit to its frequency. In order to force a coin moving within the measurement course to fall below the ejection port, a particularly strong pressing force is not required; rather, it is better to apply small continuous impact vibrations that reliably act on the coin. Effective.

The present invention reliably generates small but continuous impact vibrations for each coin that moves continuously within the measurement course, which is doubled by contact with the cog groups located above and below the endless cogged belt. It is an object of the present invention to provide a sorting device with a precise coin width that allows the coins to be sorted without omissions.

(Means for solving the problem) In order to achieve this objective, the present invention has the following configuration. That is, the coin width sorting device in a coin processing machine according to the present invention sorts coins into a measuring course whose width can be changed depending on the diameter of coins to be sorted, by pressing an endless belt that rotates along the course. In the sorting device that introduces A vibrating roller that constantly rotates in contact with the inner cog group of each belt is disposed, and the lower end of the roller is substantially aligned with the lower edge surface of the endless belt, and a coin ejector is provided on the measurement course. A sorter diaphragm located above the outlet is attached,
The roller and the sorter diaphragm are both biased downward by spring force.

(Function) This idea uses an endless belt, which is an essential member for introducing coins while pressing them, into the measurement course, and uses a belt with cogs, and rotates with the outer circumference of the upper and lower positions touching the inner cog part of this endless belt. A vibration roll is installed inside the endless belt, and a sorter diaphragm is attached to the side of the roller, the lower end of which is substantially aligned with the lower edge surface of the endless belt. This vertical movement of the vibration roll, which rotates repeatedly with small but intense vertical movements, is transmitted to the sorter diaphragm by contact with the inner cog part of the diaphragm, and the vibration plate's small and high-speed vertical vibrations are used to constantly This applies shock in small increments to the coins moving within the measurement course, which encourages harmful small-diameter coins to fall from the ejection port after passing through the course.

In addition, this endless belt is installed on the measurement course with a slight inclination in plan view with respect to the measurement course, so that the coins moving within the course are Of these, the movement is biased toward one of the forming plates.

(Example) Next, a specific example of the apparatus according to the present invention will be described using the drawings.

A hanger 2 is arranged near the periphery of the table 1 which rotates at high speed to select the thickness of coins, which can change the gap between the table 1 and the surface of the table 1 as appropriate. is introduced into the course section for measuring the diameter of the coin (Figs. 1 and 6).

This measurement course is formed by a pair of parallel members, that is, a course fixed plate 3 and a course movable plate 4.
The interval of 4 can be adjusted freely. That is, the course movable plate 4 is always urged in a direction away from the course fixed plate 3 by the spring 6, but an adjustment cam 7 is disposed in contact with the outer edge of the course movable plate 4, and is directly connected to this cam 7. As the adjustment knob 8 rotates, the adjustment cam 7 rotates, and the course movable plate 4 is pushed from the back against the elasticity of the spring 6, so that the distance between it and the course fixed plate 3 is changed as appropriate (Fig. 1, Figure 6).

At the lower inner edges of both the course fixed side and movable side plates 3 and 4, there is a holder for supporting a coin.
A pair of receiving rails 5, 5 are provided to protrude inward from the inner edges of both plates 3, 4, and between both receiving rails 5, 5, there is a tray for dropping small-diameter coins that are less than the width of a predetermined measurement course. The outlet 9 is open (FIG. 7).

Reference numeral 11 denotes an endless cog-equipped belt located above the measurement course forming plates 3 and 4, along the measurement course and slightly inclined from parallel to the course in plan view. One end of the coin receiving side of the rotary table 1 extends above the peripheral edge of the rotary table 1 (FIGS. 1 and 2). A drive shaft 14 is supported by a bracket 13 attached to the main frame of the coin handling machine, and a large pulley 15 is attached to the shaft end of the same shaft.
An arm 17 is pivotally attached to one end extension 16 with a shaft 18, and a small pulley 19 corresponding to the large pulley 15 is attached to the tip of the arm 17. The cogged belt 11 is wound, and on the measurement course,
The belt 11, which extends along the course, is distinctive in that it is arranged with a slight inclination, intentionally avoiding a line parallel to the course when viewed from above (FIG. 2).

A vibration roller 21 is arranged in the belt 11 with cogs arranged endlessly on the measurement course, with both upper and lower peripheral edges in contact with a group of 12 cogs that are continuously raised on the inner side of the belt. Furthermore, the base end of a sorter diaphragm 23 having a downward protrusion 22 at its tip is attached to the mounting shaft 18 of the arm 17, and the tip of the sorter diaphragm 23, which can swing around the mounting shaft 18, is attached to a roller 21. The roller 21 and the sorter diaphragm 23 are connected via a connecting shaft 24 (see Figs. 3 and 4).
figure). The downward protrusion 22 formed at the tip of the sorter diaphragm 23 connects its lower end to the belt 1.
1, and is located above the discharge port 9 provided within the measurement course (the fourth
figure).

A small-diameter spring 26 is stretched between the connecting shaft 24 of the sorter diaphragm 23 and the vibration roller 21 and a stud 25 implanted on the arm 17 with a small pulley 19 attached to the tip. This urges the downward protrusion 22 of the sorter diaphragm 23 and the vibration roller 21 downward (FIG. 4).

Also, a large spring 28 is installed between the stud 27 installed near the tip of the arm 17 and the bracket 13.
is stretched, and due to the tension of this spring 28,
The arm 17, which is rotatable around the mounting shaft 18, is biased downward, but the lower end of the large stud 29 fixed to the tip of the arm 17 regulates the lowering position of the small pulley 19 and, by extension, the cog belt 11. This is achieved by abutting the parts on the course fixing plate 3 (Fig. 2).

The rotation of the cogged belt 11 is carried out via a transmission belt 32 wound around a drive pulley 31 fixed to the other end of the mounting shaft 14 of the large pulley 15 (FIG. 2).

33 is a cover plate installed on the course fixing plate 3 to prevent coins from escaping from the measurement course; 34 is a star wheel that is introduced into the course and counts coins that match a predetermined diameter measurement. Yes (Figure 2).

The coins put into the rotary table 1 with a mixture of different types of coins are transferred to the hanger 2 and the rotary table 1.
The thickness of the coin is measured as it passes through the gap between the coins. In order to make the measurement course width approximately match the diameter of a predetermined type of coin to be sorted, the adjustment cam 9 is rotated to move the course movable plate 4, and the distance from the course fixed plate 3, that is, the course width is adjusted. Set.

Coins that pass through the gate for coin thickness measurement are
The cogged belt 11, which rotates and runs, moves to the course entrance part while being pressed from above, and only small diameter coins that match the course width or are narrower than the course width are sequentially introduced one by one into the measurement course. Among the coins traveling in the course, a predetermined coin whose width approximately corresponds to the course width is supported on both sides by a pair of receiving rails 5, 5, and is carried over the entire length of the course without falling from the ejection port 9. Star foil 34 in the middle
They are counted and sorted and collected at a certain location. The small-diameter coins introduced into the course together with a predetermined large-diameter coin are assisted by the belt 11 and are moved along the course by a pair of receiving rails 5, 5.
The coins fall from the outlet 9 without being supported by the coins, and are separated from the predetermined coins.

However, among the many small diameter coins, some coins that should have fallen from the ejection port 9 accidentally fall onto the receiving rails 5 and 5.
While moving at high speed, the coins are momentarily supported, pass through the ejection port zone, and are mixed into a predetermined group of large-diameter coins, causing errors in accurate sorting and totaling.

The present invention includes a vibration roller 21 that rotates while repeatedly moving up and down violently, with its upper and lower peripheral edges in contact with a group of cogs on the belt, inside a belt with cogs that rotates in an endless manner. At the same time,
A sorter diaphragm 23 is attached to the side of the roller 21, and the sorter diaphragm 23 repeatedly vibrates violently in small but small steps in the vertical direction in response to the vertical movement of the roller. The diaphragm applies small vibration shocks, and in particular, small diameter coins that are accidentally supported by the receiving rail at the discharge port 9 and try to pass through are forcibly disengaged from the receiving rail. Thus, the coins are surely dropped into the discharge port 9 and the coins can be selected with high precision. In addition, in order to ensure that small-diameter coins fall from the ejection port 9, when small-diameter coins move within the course, they are always kept on the course fixing plate 3.
Or, when moving in contact with the inner edge of either one of the course movable plates 4, the support by the receiving rail 5 at the discharge port 9 is limited to one side of the small-diameter coin, and the small-diameter coin falls in a very natural manner. It will be held at Therefore, the belt 11 arranged on the course is intentionally avoided to run parallel to the measurement course in plan view, and is installed in a slightly inclined direction with respect to the course. It is designed to run in contact with either one of the forming plates to increase the probability of falling and sorting from the discharge port 9.

By using the arm 17 and lifting the small pulley 19 side upwards using the mounting shaft 18 as a fulcrum, the course portion of the belt 11 can be opened wide, and troubles such as coins clogging in the course can be easily eliminated. Can be corrected.

(Effects of the invention) In this invention, a belt with cogs is used as the belt, which is an essential member for introducing coins into the course, and the group of inner cogs of this endless belt is actively utilized. The high-speed and small vertical movement of the vibration roller, which is generated by bringing the group into contact with its upper and lower outer peripheral edges, is transmitted to the sorter diaphragm located on the course to apply small impact vibrations to the small-diameter coins. It is possible to separate the coins from the receiving rail and, by extension, to ensure that they fall from the ejection port and sort them.By effectively utilizing the movement of the belt, which is an essential component, it is possible to achieve effective and highly accurate sorting of coins. .

In addition, the vibration roller, which is located inside the endless belt running at high speed and is arranged so that it contacts the inner cog part of the belt at both the upper and lower outer circumferential edges, is repelled by the cog group and causes violent and small vertical movements. By contacting the upper and lower peripheral edges with this endless belt, the vertical movement is doubled compared to contact with one peripheral edge, and as a result, the vibration efficiency of the sorter diaphragm can be further increased, and the vibration efficiency of the sorter vibration plate can be further increased. In this case, it is possible to increase the effect of knocking small-diameter coins out of the ejection port. In addition, when the course width is expanded due to the course movable plate being significantly separated from the course fixed plate, the coin introduction belt will inevitably deviate from the center line position of the measurement course, and as a result, the side of the coin will be removed from above. Although it is pressed, the sorter diaphragm located on the side part of the vibration roller, that is, on the side part of the belt, presses down the approximate center of the coin, which helps the large-diameter coin to run smoothly in the course. It also has a good effect.

In addition, intentionally avoiding parallel placement of the belt with respect to the measurement course, and arranging the belt with a slight inclination when viewed from above, will prevent coins traveling within the course from forming one of the course forming plates. By causing the coins to run biased toward the plate side, the discharge of small-diameter coins from the discharge port is facilitated, and the effect of knocking off small-diameter coins by the sorter diaphragm can be made even more effective. Further, by configuring the endless belt so that one pulley on one side can be lifted upward, it is possible to quickly deal with troubles caused by coins jamming in the measurement course.
