Abstract

PURPOSE:To speedily execute the moving and sorting operation of coins without fail and to take the coins in one by one without fail by utilizing one kind of forced conveying force to the supplied coins. CONSTITUTION:A coin K, which is sent into at the inclined rolling route of a coin arranging device 11 while being turned, is drawn-in by a conveying mechanism 3 while being regulated by an entrance regulating mechanism 4 so as to enter one by one. Then, the coin is position of a sorting rail surface 2b of a rail board 2a in a standing posture. Afterwards, the coin is pressed on a supporting surface, conveyed by a conveyer belt 3e, which is traveling, and enters the interval of a defective coin detecting mechanism 5. When the coin K entering this interval is defective, a detecting board 5a is pushed up from the side of a supporting surface 2i by the coin K entering the interval, vibrated and displaced. Accordingly, detecting signals are outputted form the defective coin detecting mechanism 5 and the coin is made fall and ejected by an ejecting mechanism 6, which is arranged in a downstream, according to the input of the detecting signal. Thus, the exact and secure sorting operation can be obtained for the coins and time for processing is shortened. Then, the coin can be received one by one without fail.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for sorting coins by type, which are separated from tickets and sent one by one from a coin sorting device, in a fare collecting machine installed in a one-man bus or the like. This relates to a coin sorting device that sorts coins.
In addition to regulating each coin individually, it also allows for the smooth detection and discharge of defective coins due to deformation. [
[Prior art] Various configurations are used as coin sorting devices for fare collection machines installed in one-man buses, etc., but a typical conventional coin sorting device is
There is one shown in Publication No. 9870. The coin sorting device disclosed in Japanese Utility Model Publication No. 19870/1987 is composed of a bad coin ejecting mechanism section having a defective coin detection ability and a coin sorting mechanism section. By forming a certain gap between them, a path through which only normal coins can pass is formed, and a defective coin ejection plate opens this passage downward at a certain timing, and this defective coin ejection plate has a shape. The coin sorting mechanism section also consists of a coin feeding mechanism that feeds coins into the gap at a certain timing, and a coin sorting mechanism section that sorts the coins being conveyed by the conveyor belt into diameter dimensions on a sorting board based on the sorting rail surface. It is configured to select based on differences. The opening operation of the defective coin ejection plate and the coin feeding operation in the defective coin ejection mechanism section are performed intermittently at a fixed timing, whereas the coin transport in the coin sorting mechanism section is continuous. ing. Further, passage of coins through the passage formed by the defective coin discharge plate is achieved only by transfer due to the coin's own weight.

[Problem to be solved by the invention]

According to the defective coin detection means disclosed in Japanese Utility Model Publication No. 19870/1987, which is the prior art, deformed defective coins cannot be transferred through the path defined by the defective coin ejection plate using only their own weight. For this reason, the coin gets caught in the defective coin ejection plate, and is reliably ejected by the opening operation of the defective coin ejection plate at a certain timing, but the coin passes through the path shaped by the defective coin ejection plate. This is because the transfer operation is based on the coin's own weight, so it is not possible to shorten the time required for one coin to pass through the defective coin discharge plate passage, which causes the problem that the coin processing time becomes longer. be. In addition, since each coin passes through the defective coin ejection plate passage only by transfer due to its own weight, even a normal coin can pass through the defective coin ejection plate passage due to slight resistance due to adhesion due to dirt, catching on unevenness, etc. There is a tendency for situations in which this cannot be achieved smoothly, resulting in the problem of normal coins being illegally discharged.

Then, the coin sorting mechanism sorts the types of coins based on the diameter dimension based on the sorting rail surface, but the coins are sorted while being lifted from the sorting rail surface due to vibration etc., and the sorting process is completed. There was a problem that it would be inaccurate.

Furthermore, since the coin sorting device shown in Utility Model Publication No. 63-19870 is based on the assumption that coins to be sorted are supplied one by one, two or more coins may be fed in overlapped for some reason. Then, there was a problem that all of the supplied coins would be discharged as defective coins, or the sorting operation would become impossible.

Therefore, the present invention was devised to solve the above-mentioned problems in the conventional technology, and by utilizing one forced conveying force for the supplied coins, the movement and sorting operation of coins can be reliably performed. And while quickly achieving the precepts,
The object of this invention is to detect and eject defective coins without adversely affecting the conveyance of coins, and to ensure that coins are taken in one by one.

[Means to solve the problem]

Means of the present invention for achieving the above object is a device that constitutes a fare collection machine installed in a one-man bus, etc., which separates coins from tickets and separates them from coin sorting devices and separates them by type. It is a coin sorting device that sorts coins, by placing a coin upright on the sorting rail surface, which is the top surface of a rail plate, with one end surface of the coin supported by a support surface,
It has a sorting passage type mechanism that sequentially sorts coins according to the difference in diameter based on the sorting rail surface, and uses the frictional resistance between the brake roller and the coins.
It must have an intrusion prevention mechanism that prevents two or more coins fed from the coin alignment device from entering in piles, and a gap approximately equal to the width in the thickness direction of a normal coin should be left between it and the supporting surface. The detection plate is provided to be swingable and has a defective coin detection mechanism that detects defective coins by the pivoting displacement of the detection plate, and a portion of the supporting surface is detected by inputting a detection signal from the defective coin detection mechanism. It has an ejecting mechanism that opens the coin and ejects detected defective coins.

In addition to the above means, it is preferable to provide a holding mechanism for pressing the coins conveyed by the conveyance mechanism onto the sorting rail surface upstream of the sorting function part where the sorting plate of the sorting path forming mechanism is formed. In addition, it is preferable to set the relative height distance of the transport bematome to the sorting rail piece formed by the rail plate so that it becomes smaller as it goes downstream in the transport direction. At the end,
It is better to form an ascending slope.

The brake roller of the intrusion control mechanism exerts an intrusion control effect by exerting a frictional resistance force on the coin when the coin is pressed against its circumferential surface, so it is placed at the upstream end of the conveyance mechanism in the conveyance direction. It is desirable to provide a brake roller opposite the belt wheel. The ejection mechanism is disposed downstream of the defective coin detection mechanism, and is actuated by the ejection plate that forms part of the support surface and is movable up and down, and is activated by the input of a detection signal from the defective coin detection mechanism to eject the coins. It is best to avoid using a plunger that displaces the plate upward. [Operation] The coins transferred through the inclined transfer path of the coin sorting device are transported while being restricted by the intrusion restriction mechanism so that two or more coins do not overlap and intrude one at a time. It is pulled in by a mechanism and placed in an upright position on the sorting rail surface of the rail board while being pressed against the support surface. The coins located on the sorting rail surface are conveyed while being pressed against the support surface by the conveyor belt of the running conveyance mechanism, and first enter the gap formed by the detection plate of the defective coin detection mechanism. If the coin that has entered this gap is a normal coin, the width of the coin in the thickness direction is smaller than the preset gap value, so the detection plate will be pushed up from the supporting surface side by the coin that has entered the gap. There is no rocking displacement, and no detection signal is output from this defective coin detection mechanism. On the other hand, if the coin that has entered the gap is a defective coin that has been deformed, the width in the thickness direction of the coin is larger than the preset gap value, and the detection plate is Since the coin is pushed up and oscillated, the defective coin detection mechanism outputs a detection signal. The ejecting mechanism disposed downstream of the defective coin detection mechanism retracts the ejecting plate, which forms part of the support surface that supports the coins being conveyed while being pressed by the conveyor belt, in response to the input of the detection signal. Therefore, the defective coins that have been conveyed by the conveyor belt and passed through the defective coin detection mechanism are dropped and discharged from the part where the discharge plate has retreated.

If the defective coin detection mechanism does not output a detection signal, that is, if the coin is a normal coin, the ejection mechanism does not operate, and the coin is directly conveyed by the conveyance mechanism to the sorting function portion formed by the sorting plate of the sorting path forming mechanism, They are then sorted according to their diameter.

The holding mechanism holds the coins being transported by the transport mechanism.
It is pressed onto the sorting rail surface, which is the upper surface of the rail plate, to accurately sort out coins based on the difference in diameter with respect to the sorting rail surface.

In addition, the height distance of the conveyor belt relative to the sorting rail surface is
By decreasing the size toward the downstream in the transport direction,
The coins held under pressure between the conveyor belt and the support surface receive a force from the conveyor belt that presses them onto the sorting rail surface as the conveyance progresses, which prevents the coins from lifting off the sorting rail surface. Prevented. Similarly, by forming an upward slope on the sorting rail surface at the upstream end in the conveyance direction, the coins being conveyed are forcibly displaced upward against the frictional resistance between them and the conveyance belt. This upward displacement ensures that the lower end is brought into contact with the sorting rail surface.

○Sorting passage forming mechanism 2 (see Figure 3) Coin K? 7) On the back side of the rail plate 2a forming the sorting rail surface 2b which is a running surface, there is a road forming a supporting surface 2i that is located on the sorting rail surface 2b and supports the coins K pressed by the conveyor belt 3e. A side plate 2e, a sorting plate 2g, and a receiving plate 2d are assembled, and the coin K travels on the sorting rail surface 2b while maintaining an upright position sandwiched between the supporting surface 2i and the conveyor belt 3e. The receiving plate 2d and the sorting plate 2g form a supporting surface 2i when combined, but the receiving plate 2d supports only the lower end of the coin K, and the sorting plate 2
g supports only the upper end of the coin K, receiving it temporarily 2d and sorting jl
There is an open space between it and i2g.

A plurality of sorting steps 2h are formed on the lower edge of the sorting plate 2g, and the height distance from the sorting rail surface 2b increases stepwise along the conveyance direction, and the sorting rail of each sorting step 2h is formed. A coin K with a small diameter depending on the value of the height distance from the surface 2b
Sort in order from In other words, coins K with a diameter larger than the height distance from the sorting rail surface 2b to the sorting step 2h are
In this sorting step 2h, the upper and lower ends are supported by the sorting plate 2g and the receiving plate 2d, so the receiving plate 2d and the sorting plate 2g
Although it cannot fall between the sorting rail surface 2b
For coins K having a diameter smaller than the height distance from the top to the sorting step 2h, the upper end of the coin K is no longer supported by the sorting plate 2g.
2d and sorting IJi. It falls to the open back side between 2g and is stored and held there.

Incidentally, an ascending slope 2c is formed on the sorting rail surface 2b at the starting end of the conveyance, so that the coins K fed from the coin alignment device 1l and conveyed are forcibly displaced upward.

○ Transfer mechanism 3 (see Figure 2) A base plate 3a is arranged and fixed on the front side of the rail plate 2a of the sorting passage type control mechanism 2 along this rail plate 2a, and a motor pulley 3c is attached to one end of this base plate 3a. A motor 3b provided with
is fixed, and a belt pulley 3d is provided at the connection portion with the coin aligning device 11 at the other end. An endless pupil conveying belt 3e is stretched between the belt pulley 3d and the motor pulley 3c. It is installed in a tilted position in the direction approaching.

Between the motor pulley 3c and the belt pulley 3d, a swinging arm 3g is rotatably attached to a swinging arm 3g, which is individually fixed to the shaft +fi 3a so as to be swingable, and always supports the conveyor belt 3e by the upward force of a spring 3h. A large number of presser wheels 3f are provided to press against the 2i side, and the pressure of the large number of presser wheels 3f on the conveyor belt 3e causes the conveyor belt }
The coin K can be supported between the support surface 2i and the support surface 2i.

○ Intrusion control mechanism 4 (see Fig. 5) A brake roller 4 is placed opposite the belt wheel 3d disposed at the input end of coins K from the coin aligning device 1l of the coin sorting device 1.
The brake roller 4a and the belt pulley 3d form the coin Kl entrance of the coin sorting device 1.

The brake roller 4a has a circumferential surface made of a strong elastic material, and a pressing elastic piece 4c attached to a fixed bin 4b fixed to the roadside board 2e is strongly pressed against the circumferential surface on the opposite side of the belt pulley 3d. By making elastic contact with the wheel, it is attached so that it is difficult to rotate while being pressed against the Helt wheel 3d.

Since a distance corresponding to one coin K is formed in advance between the brake roller 4a and the conveyor belt 3e stretched over the belt pulley 3d, one coin K is transferred to the coin aligning device l1.
, the coins K are taken into the coin sorting device 2 by the conveyor belt 3e despite the resistance force of the brake roller 4a, but two or more coins K are fed from the coin sorting device 11 at the same time. When the coins K other than the coins K that are in contact with the conveyor belt 3e are fed in an overlapping state, the braking action of the brake roller 4a acts on the coins K other than the coins K that are in contact with the transport belt 3e, and the coins K other than the coins K that are in contact with the transport belt 3e are The entry of the coin K into the coin sorting device 1 is prevented until this coin K can come into contact with the conveyor belt 3e, that is, until the entry of the first coin K is completed. The intrusion of coins K is restricted to one at a time.

○ Defective coin detection mechanism 5 (see Figures 2, 3, 5, and 6) There is a gap between the roadside board 2e and the supporting surface 2i that is approximately equal to the maximum thickness width of a normal coin K. The detection plate 5a, which is arranged with an equal gap S, is immovably fixed to the lower end of a rotating shaft 5b that is rotatably mounted upright on the base plate 3a, and is fixed to the upper end of the rotating shaft 5b. A fan-shaped gear 5c is fixed in such a manner that the tip thereof forming the gear extends beyond the roadside plate 2e. The fan-shaped gear 5c meshes with a driven gear 5d fixed to a holding shaft 5f rotatably attached to the upper end of the roadside plate 2e. A transmission gear 5e is fixed to a holding shaft 5f to which a driven gear 5d that meshes with the fan-shaped gear 5c is fixed, and a transmission gear 5e is attached to the upper end of the roadside plate 2e in the same way as the holding shaft 5f. Rotary gears 5g attached to the attachment shaft 5k are meshed. Rotating gear 5
A displacement arm 5h with a light shielding piece 51 attached to its tip is fixed to g, and the displacement arm 5h has the light shielding piece 51 at its tip immovably attached at a fixed position while the detection plate 5a is not rotated. The photocoupler 5j is positioned at a light shielding position relative to the photocoupler 5j.

One end of a spring 5m is connected to the transmission gear 5e, and the tensile elasticity of the spring 5m causes the detection plate 5a to
is supported by the gap S and is opposed to the light shielding piece 2i, and the light shielding piece 51
is located at a light shielding position with respect to the photocoupler 5j.

Even if a normal coin K, that is, a coin K whose substantial width in the thickness direction has not increased due to deformation, enters into the gap S, the defective coin detection mechanism 5 detects a coin K that has entered the gap S.
As a result, the detection plate 5a does not rotate around the rotation shaft 5b, so the light shielding piece 51 remains shielding the photocoupler 5j, and therefore the photocoupler 51 does not output an output signal, that is, a detection signal. On the other hand, when a defective coin K whose substantial width in the thickness direction has increased due to deformation enters the gap S, the detection plate 5a is pushed by the defective coin K, and the detection plate 5a is pushed in the direction of the arrow in FIG. rotationally displaced,
This rotational displacement of the detection element 5a causes the displacement arm 5h to rotate in the direction of the arrow and detach the light shielding piece 5 from the photocoupler 5j, so the photocoupler 51 is activated and outputs a detection signal.

As is clear from the above explanation, the defective coin detection mechanism 5 only detects whether the passing coin K is good or defective, and allows the coin K to pass regardless of whether it is a normal coin K or a defective coin K. .

○Wandering mechanism 6 (see Figures 2, 3, 4 and 5) The discharge plate 6a is located between the roadside +Ii2e and the sorting plate 2g.
It is located so as to form a part of the support surface 2i, and is assembled so that it can be moved upwardly to a position where the coin K can be evacuated from within the transport path, and has a vertically elongated guide hole 5b in the center.
is drilled and attached to the fixed part in this guide hole 5b,
A guide pin 6c is slidably engaged to maintain a constant posture of the ejection plate 5a during vertical displacement, and a plunger 6d fixedly attached to a fixed portion is attached to the upper end of the ejection plate 6a.
The plunger rods are connected.

In this ejecting mechanism 6, the ejecting plate 6a is normally located at the lower end to form a support 2i, so that the conveying bell 3e can convey the coins K to the sorting section. , when a detection signal is output from the defective coin detector JR 5, this detection signal becomes an operation command signal to operate the plunger 6d, raise and retract the temporary ejector 6a, and locate the ejector plate 6a. A coin K discharge port is formed at a location on the support surface 2i, and defective coins K are discharged from this discharge position to a predetermined location. The plunger 6d is operated by a conveyor bell}
This continues for a certain period of time calculated according to the traveling speed of coin 3e, and after this certain period of time has elapsed, the discharge plate 6a is immediately returned to its original position to handle the passage of the next coin K.

○ Holding mechanism 7 (see Figures 2, 3, 4, and 5) A holding mechanism whose tip protrudes from the back side of the roadside board 2e to the front side in the window hole 2f opened in the roadside board 2e. The bottle 7a is attached to the tip of a crank arm 7b which is rotatably fixed on a support shaft 7c on the back surface of the roadside temporary 2c, and a presser pin 7a is attached to the other end of the crank arm 7b in the direction of lowering it. A spring 7d that exerts elasticity is connected.

Due to the action of this spring 71, the holding pin 7a is located at the downward displacement limit, but the height distance from the sorting rail 2b of the lower end of the peripheral surface of the holding pin 7a located at the downward displacement limit is the smallest in diameter. It is set to a value slightly smaller than the diameter of the coin K. Therefore, when the coin K conveyed by the conveyor belt 3e passes through the presser pin 7a, the coin K is always pressed against the sorting rail surface 2b by receiving the downward force from the presser pin 7a, so that the coin K always reaches its lower end. The paper is transported in a constant state in which it is in contact with the sorting rail surface 2b.

〔Effect of the invention〕

Since the present invention has the above-described configuration, it has the following effects. Since the coin entry control operation, defective coin detection operation, and ejection operation are accomplished using a single coin conveying operation and conveying force, the configuration of the driving part of the entire device is extremely simple. In addition, each operation can be made simple.

Since the coin intrusion control mechanism, defective coin detection mechanism, discharge mechanism, and coin sorting function section can be arranged in order along the conveyance path defined by a single conveyance mechanism, the necessary processing of coins can be performed in order. This can be achieved efficiently, thereby making it possible to extremely shorten the processing time required for coins.

Since the coins are forcibly conveyed by the conveyor belt that holds the coins between the support surface and the coins, the coins are conveyed reliably and powerfully, which causes defects in the sorting operation due to poor coin conveyance. can be completely eliminated.

Since the intrusion control mechanism always accepts coins one by one, the conveyance, defect detection, ejection, and sorting of the fed coins can be accomplished reliably, accurately, and stably.

By providing a holding mechanism, making the conveyor belt slope with respect to the sorting rail surface that is the conveying path, and forming an upward slope at the starting end of the sorting rail surface, the coin sorting rail that is conveyed by the conveyor belt is improved. The positional relationship with respect to the surface can be maintained constant, thereby making it possible to obtain accurate and reliable coin sorting operations.
