Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a coin counting machine for sorting and counting mixed coins of multiple denominations, and more specifically, the number of coins of a given denomination can be set for each coin of each denomination. This is related to the process of setting the number of sheets to be counted.

<Prior art> Conventionally, coin counting machines that sort and count mixed coins of multiple denominations by denomination have been configured so that, in addition to the normal sorting and counting functions, the number of coins to be counted can be set in advance as necessary. It has a preset function.

Also, targeting mixed coins of multiple denominations,
Various technologies have been proposed for coin counting machines that can perform sorting and counting at the same time, and although this preset function is not described, for example, as shown in Japanese Patent Application Laid-Open No. 58-214989, There are several configurations that can be mentioned.

In this case, a flat coin sorting passage is provided with a plurality of coin discharge ports arranged in order from small diameter coins to large diameter coin discharge ports, and a transfer belt is installed facing above each coin discharge port, and each coin discharge port is arranged in order from small diameter coins to large diameter coin discharge ports. A limit switch (coin detection sensor) is disposed at the side edge of the outlet, and a material discrimination sensor is disposed in front of the first coin ejection port.

Then, while each denomination is discriminated by the material discrimination sensor, each limit switch detects the coin of each denomination falling into the coin ejection port, and the contents of both outputs are compared to identify the coin of each denomination. I'm trying to count the numbers.

<Problem to be solved by the invention> Although the above-mentioned coin counting and processing machine does not include a preset function, if a preset function is added to the coin counting and processing machine,
When one of the multiple denominations reaches the set value,
It is configured to determine this based on the output from a limit switch serving as a coin detection sensor. When the limit switch detects that the set number of coins of any denomination has been reached, based on the detection output, all transfer belts are activated to prevent coins of the same denomination from being detected again. However, coins that are still being transported between the time of this detection and the time of stopping will stop on the sorting path before reaching the designated coin drop port, and therefore, it will be difficult to identify the material. Even if there is an output from the sensor, there is no output from the limit switch side, so counting is interrupted and accurate counting cannot be performed, which has the problem of affecting other counting and sorting functions. .

The present invention was developed in view of the above circumstances, and when a detection output of the set number of coins is obtained for any predetermined amount regarding setting an arbitrary number of coins of multiple denominations, for coins of other denominations, To provide a coin counting processor capable of performing continuous sorting and counting for presetting without affecting the results of sorting and counting up to that point.

<Means for solving the problem> The present invention supplies mixed coins of multiple denominations onto a rotating disk, moves them to the periphery by centrifugal force due to rotation of the rotating disk, and sends them to a coin passage. In the coin counting and processing machine, the coins are sorted by denomination by being sent to a coin sorting passageway having a coin droplet for each denomination arranged from small diameter coins to large diameter coins by using a guide with a curved wall. A coin discrimination sensor that discriminates the denomination of coins and outputs a count is disposed facing the coin passage, and the curved wall-mounted guide located at the tip of the coin passage is formed to be movable up and down, and is disposed straight ahead of the guide for ejecting coins. Place a return box to store coins,
When setting the number of coins to be counted, the curved wall-mounted guide is lowered to the transport surface position based on the detection output of the set value from the coin discrimination sensor, and the coins after the set number are moved straight and stored in the return box, and other set coins are stored in the return box. is guided to the coin sorting passage before the curved wall guide is activated.

<Function> In the coin counting and processing machine according to the present invention, when the coin discrimination sensor placed facing the coin passage detects that any denomination has reached the set value, the coin counting and processing machine according to the present invention bends based on the detection output. The wall-mounted guide is lowered to the transport surface position, and the subsequent coins that have reached the set value are allowed to go straight ahead and are stored in the return box, while the coins that have reached this set value and the coins that are transported in front of the coins are The other coins on the passage are sent to the sorting passage before the curved wall-mounted guide operates, and the curved wall-mounted guide returns to its original state and the operation of feeding coins from the rotating disk is completed. When the coin sorting is resumed, coin sorting and counting will continue for the other denominations whose sorting has been temporarily suspended until the set value for any denomination is reached again.
Also, at this time, the counted value is continuously added to the counted value when the sorting operation was interrupted when the previous set value was reached.

<Example> Hereinafter, the coin counting processing machine of the present invention will be explained based on the drawings.

In FIGS. 1 and 4, reference numeral 1 denotes a centrifugal force type coin supply unit consisting of a rotary disk 2 on which coins A of various denominations are placed, and a cylindrical peripheral wall 3 standing upright on the peripheral edge 2a. A coin passage 5 faces the side of a feeding groove 4 which is cut out in the lower part of the peripheral wall part 3 and has a width approximately equal to the thickness of one coin.

Further, on the outer side of the feeding groove 4, there is provided a bending arm member 6 for shutter/guidance that plunges into the coin when the coin is jammed. A take-in roller 7 is arranged at the entrance of the coin passage 5, which is a straight path, and a pair of endless conveying ropes 8 are stretched in parallel across the entire conveying surface 5a in front of the coin passage 5, and on both sides of the intermediate position. In order to obtain a discrimination output for the denomination of the coin and a counting output for each denomination, the coin discrimination sensor 9 includes an optical detection means and measures the outer diameter of the coin, and a magnetic detection means measures the outer diameter of the coin. The other coin discrimination sensor 9, which detects the material, is disposed in an opposing state, and the opposite coin discrimination sensors 9, 9 are provided, and the straight forward end of the coin passage 5 has a height of coin thickness as shown in FIG. A plate-shaped guide 10 having a curved wall 10a and serving as a return is installed. Reference numeral 11 denotes a sorting passage installed orthogonally on one side of the curved wall end of the guide 10, and on the conveying surface 11a of the sorting passage 11, drop ports 12 are arranged in order from small diameter to large diameter.
The chute 13 for each denomination is installed in a row for the number of denominations (6 pieces for 1, 5, 10, 50, 100, and 500 yen coins), and the chute 13 for each denomination is installed in front of the various drop openings 12. A detection sensor 14 is arranged. 15 is sorting passage 1
A pair of transport ropes are stretched in parallel to the transport surface 11a of the transport rope 15, and a taper roller 16 for pushing down coins is provided at each drop opening 12 position on the carrier side of the transport rope 15. The spring 17 is supported by an attached support piece 18 and is in contact with the conveying rope 15 surface. A taper roller 19 presses against the carrier surface of the transport rope 8 located at the coin discrimination sensor 9, and presses the coin A toward one of the coin discrimination sensors 9 for correct detection. Reference numeral 20 denotes a return solenoid attached to the lower part of the guide 10. As shown in FIG. 10b is configured to protrude from the conveyance surface 5a by the thickness of the coin. Reference numeral 22 indicates a timing sensor disposed at a position on the transport surface 5a in front of the guide 10, and reference numeral 23 indicates a confirmation sensor interposed between the guide 10 and a return box 24 disposed straight ahead thereof. Then, the detection signals from the coin discrimination sensors 9, 9 are compared with data signals regarding the diameter, material, etc. of the coin for each denomination read out from the ROM 27 in the control unit 28, and if the output contents of both coincide, , the coin is determined to be normal and the counting operation continues.

The fifth is a block diagram of the control relationship in the coin counting processing machine shown in FIGS. Reference numeral 28 indicates a ROM that stores data regarding the outer diameter dimensions, materials, etc. of coins of each denomination to be counted, and 28 indicates a control unit that controls the operation of the circuit system based on outputs from various sensors and input means. The control unit is a CPU (not shown)
connected to.

Based on the above configuration, next we will explain the operation in the fifth section.
This will be explained with figures.

First, the coin supply section 1, which serves as a coin supply tank, is filled with coins A group in which denominations are appropriately mixed.
A rotary disk 2 at the bottom of the coin A is rotated, and the coins A are horizontally fed out one by one into a coin passage 5 through a feeding groove 4 using its centrifugal force. In this case, the shutter/guiding bending arm member 6 facing the feeding groove 4 is
The solenoid 25 attached to this hooked base 6a is
OFF, and the bending arm member 6 is fed out into the groove 4.
It does not rush into the transport surface 5a, but waits at a position outside the transport surface 5a.

Here, the coin A delivered to the coin passage 5
are sequentially sent to the destination by a take-in roller 7 and a transport rope 8. In this case, the coin discrimination sensors 9, 9 disposed in the middle of the coin passage 5 detect the diameter, material, etc. of each coin A of a plurality of denominations, and also measure the number of coins. Next, the coin A that has advanced to the tip of the coin passage 5 comes into contact with the curved wall 10a of the plate-shaped guide 10, which serves as a contact wall, and shifts laterally along this curve, and is sorted perpendicularly to the coin passage 5. Move to passage 11. The coins A that have proceeded to the sorting passage 11 are advanced by the conveyance rope 15 and fall into the drop opening 12 having a diameter that matches the denomination of the opening in the conveyance surface 11a, where they are sequentially sorted by denomination and The number of coins for each denomination is counted by a denomination detection sensor 14 disposed at a position in the drop port 12. Note that a detailed explanation of this counting method will be omitted since it is not directly the gist of the present invention.

Next, a case will be described in which a preset number of predetermined coins A is preset for each predetermined coin A among the mixed coins.

In this case, first, the number of coins to be stopped is arbitrarily set for each denomination using the setting input section 26. Therefore, as described above, each coin sent out from the rotating disk 2 is conveyed through the coin path 5, The coin discrimination sensors 9, 9 discriminate the denominations and count each denomination. During this counting, if it is detected that any of the denominations has reached the set number, the control unit 28
issues a stop signal and activates the solenoid 20.

Then, coins after this set number that are in the passage are stored in the return box 24. That is, one more sheet (n+1) than the set number of denomination detection sensors 14 in the predetermined drop opening 12 of the sorting passage 11 (for example, when the denomination reaching this set value is set as n).
When the number of coins is read by the coin discrimination sensors 9, 9, the solenoid 20 is activated, and as shown in FIG. 3B, the guide 1 integrated with the operating shaft 20a of the solenoid 20
0 is lowered to the conveyance surface 5a. In this case, when the setting number n is input, in the control section 28, (n+1) is set in terms of the circuit. Therefore,
Coins other than the set coin A that went straight on this conveyance surface 5a
Since the lateral transfer guide 10 does not protrude forward, A′, that is, the (n+1) coins and the other subsequent coins, pass through the upper surface 10b of the guide 10 and go straight to the return box 24. It's something to be put into. Of course, all of these coins A pass through the timing sensor 22, and when the coin discrimination sensors 9, 9 detect that the set number of coins has been reached, another coin A is placed on the conveying surface 5a. In this case, the solenoid 20 does not work on the coin A, and the coin A is moved through the guide 1 protruding from the conveyance surface 5a.
0, the coins A are moved laterally, and are allowed to proceed to other drop ports 12 corresponding to the respective sorting passages 11. Based on the passing output of the timing sensor 22, the coins A
When it is confirmed that all the groups have passed through the coin passage 5, the control section 28 operates the solenoid 20 as described above, and the operation of discharging the coins A' group other than the set coin A is performed. Also, if necessary, actuate the shutter solenoid 25, which serves as the entrance to the coin passage 5, at the same time as the stop signal of the set coin A,
In conjunction with the solenoid 25, the shutter/guide bending arm member 6 is rotated to stop feeding out the coin A on the rotary disk 2.

Then, the confirmation sensor 23 monitors the passage of the coins A' group other than the set coin A, and when it is confirmed based on the passage output that all the coins have passed over the coin passage 5, the control unit 28 controls the solenoid By stopping the operation of the solenoid 20 and then the solenoid 25, coins are again ejected from the rotary disk, and the operation continues for presetting of coins of other denominations.

<Effects of the invention> According to the coin counting and processing machine according to the invention, when it is detected by the coin discrimination sensor that a set value has been reached for any denomination among multiple denominations, the curved wall guide is activated. After descending and reaching the set value on the coin path, subsequent coins will not be sent to the sorting path, but will go straight ahead and be placed in the return box, and will be surely ejected from the coin path. Therefore, when the curved wall-mounted guide returns to its original state and the operation of feeding coins from the rotating disk resumes, any other denomination is set again for the other denominations whose sorting and counting is temporarily suspended. Until the value is reached, it is possible to continue to perform cumulative addition to the previous count value of each denomination, and even when any denomination reaches the setting, the detection is performed by the coin discrimination sensor. Therefore, a set number of sorted coins of a predetermined denomination can be reliably obtained without affecting the sorting of other coins as in the conventional method.
