Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin processing machine, and more particularly to a coin processing machine for automatically setting the width and height of a coin passage for processing such as counting coins from inserted coins. It is about.

[0002]

2. Description of the Related Art A conventional coin handling machine will be described by taking a coin handling machine (i.e., a coin wrapping machine) that stacks a predetermined number of coins and wraps the collected coins in a wrapping paper. Conventionally, such a coin processing machine is described in, for example, JP-A-59-121491.

The coin processing machine described in this publication conveys coins one by one from a rotating disk and conveys them on a coin passage, in which small coins are sorted, and the coins to be packed are counted.
While performing processing such as stopping, coins are sent to the coin stacking section provided at the end of the coin passage and sequentially stacked,
When a predetermined number of coins have been accumulated, the accumulated coins are moved to the wrapping unit and wrapped with wrapping paper.

The coin passage and the coin accumulating portion are adjustable so that the passage width, height (thickness allowable value) and inner diameter of the accumulating portion can correspond to denominations in order to process coins having different diameters and thicknesses. Has been done. That is, the coin passage width is
Among the members forming the coin passage, a movable passage member that is movable in the width direction of the coin passage is brought into contact with a polygonal cam, and the cam is manually rotated by operating the denomination setting handle. One of the cam surfaces is selected so that the cam surface moves the movable passage member to a position corresponding to the diameter of the coin to be processed.

The height of the coin passage is defined by a thickness regulating member for regulating the coins sent from the rotating disc in a single-layer state.
The movable belt is supported by a movable frame that can move up and down by pressing it against the upper surface of the coin, and the height of the movable frame is moved up and down by manually rotating the height adjustment knob. Is adjusted.

Further, the coin stacking section is constructed by projecting a supporting section for supporting the lower surface of the peripheral portion of the coin on a belt surface of a pair of belts arranged so that their traveling surfaces face each other. Each of them is movably supported by a parallel link, and by moving this parallel link by one polygonal cam that interlocks with the denomination setting handle, the distance between the pair of belt surfaces can be adjusted according to the diameter of the coin to be processed. The inner diameter of the accumulating portion is adjusted by adjusting.

In the coin wrapping unit, the three wrapping rollers are gradually brought closer to each other while rotating, and the accumulated coins are sandwiched, and the wrapping paper is fed between the rollers and the accumulated coins to move around the accumulated coins. Along with the winding, the upper and lower ends of the wrapping paper were folded and crimped by a winding needle.

[0008]

In the conventional coin processing machine, however, the denomination setting handle is manually rotated in accordance with the denomination of the coin to be processed to adjust the width of the coin passage and the inner diameter of the accumulating portion. On the other hand, since it is necessary to manually rotate the height adjusting knob to adjust the height of the coin passage, there is a problem in that the operation for changing the denomination of the coin to be processed is diverse and extremely troublesome.

Further, since the cam for adjusting the width of the coin passage and the inner diameter of the stacking portion is formed in a polygonal shape corresponding to several kinds of coins to be processed, for example, a coin processing machine is exported to another country. In that case, a cam suitable for the circulating coins of the export destination country had to be separately incorporated into the coin processing machine, and therefore the coin processing machine could not be mass-produced and stocked.

Further, when the denomination, the number of coins in circulation increases, or the diameter of coins changes, the cam in the coin processing machine must be replaced with a new one, which requires a great deal of replacement work. There was the problem of requiring time and money.

As a coin processing machine for solving such a problem, the applicant of the present application has already proposed a machine capable of automatically setting the passage width, the passage height and the like according to the coin information stored inside. (Japanese Patent Application No. 4-35389)
issue).

However, even in such a coin processing machine, the operator has to investigate the thickness and diameter of the coin in advance, and the investigated information is input to and stored in the coin processing machine. However, it is not sufficient in terms of eliminating the troublesomeness of the operation. further,
If there is a slight manufacturing variation among the coin processing machines, it may occur that the reliable processing cannot be performed even if the thickness and diameter of the coin are simply given.

The present invention has been made in view of the problems of the prior art as described above, and provides a coin processing machine which can deal with any kind of coins and can easily set coin information. The purpose is to

Behind a straight edge portion 17b having a step 17a for forming a sorting groove, an extension portion 20 extending horizontally is provided, and this extension portion 20 is bored in a direction orthogonal to the edge portion 17b. Guide rollers 22, 22 axially attached to the machine body 2 side are fitted in the long holes 21, 21 to support the movable passage member 17 so that the movable passage member 17 can move linearly in a direction in which the movable passage member 17 separates from and comes in contact with the fixed passage member 16. A cam follower 23 axially attached to the portion 20 is constantly abutted on the peripheral surface of a stepless cam 25 rotatably attached to the machine body 2 side about a shaft 24 under the bias of a spring 26.

The stepless cam 25 has a spiral shape in which the radius gradually increases from the minimum radius portion 25a to the maximum radius portion 25b, and the convex portion 25 is formed on the minimum radius portion 25a.
c and a recess 25c 'are formed. Here, when the cam follower 23 is located outside the convex portion 25c, the movable passage member 17 is in the minimum open position, which is the initial position (see FIG. 4). On the other hand, when the cam follower 23 is fitted in the recess 25c ', the movable passage member 17 is placed in the maximum open position (see FIG. 5).

S ₁ is a fixed position detection sensor for detecting the minimum open position. That is, the fixed position detection sensor S
_The initial state is when ₁ is on (see Fig. 4). The stepless cam 25 is rotated by a pulse motor M ₁ over a predetermined angle.

At the downstream end of the movable passage member 17, one end of an auxiliary passage member 27 which is L-shaped when viewed from above is provided with a pin 28.
Are connected by. The other end of the auxiliary passage member 27 is in contact with a guide 29 fixed to the machine body 2 side by a biasing force of a spring 30. Thereby, the movable passage member 17
The position of the passage surface 27a of the auxiliary passage member 27 changes with the movement of. That is, when the movable passage member 17 is in the fixed position (that is, when the passage width of the coin passage 6 is minimum),
As shown in FIG. 4, the passage surface 27a has a movable passage member 17
Is linearly located with respect to the edge portion 17b, and as the movable passage member 17 moves to widen the passage width, the edge portion 17b
It is displaced to a slightly bent position with respect to b (see FIG. 5). With such a configuration, even if the passage width is changed, the end of the coin passage 6 is directed toward the center of the coin accumulating portion 7, so that the coin can be guided to the coin accumulating portion 7 regardless of the passage width. it can.

The end of the passage outlet bottom plate 18 on the side of the movable passage member 17 is rotatably supported by the shaft 31 toward the machine body 2 and the pin 32 protruding from the lower surface of the passage outlet bottom plate 18 is provided. Is fitted in the long hole 34 of the portion 33 of the movable passage member 17 extending toward the coin passage 6 side. As a result, when the movable passage member 17 is moved in a direction to widen the passage width, the passage outlet bottom plate 18 is moved through the elongated hole 34 and the pin 32 to move the shaft 31.
Rotate counterclockwise in the figure about the center.

On the free end side of the passage outlet bottom plate 18, an auxiliary passage member 35 is provided which is an extension of the edge portion 16b of the fixed passage member 16 having the step 16a, and the number of coins passing downstream is counted. A count sensor S ₂ and a check sensor S ₃ for checking whether or not a coin has passed are provided. These sensors S ₂ and S ₃ are magnetic sensors or photosensors. The count sensor S ₂ corresponds to a second sensor that detects that a coin has passed through the coin passage. In addition, these sensors S ₂ , S ₃
Between them, a stopper 36 is provided so as to be able to advance on the coin passing track. The stopper 36 is operated by a solenoid (not shown), and in the initial state, the stopper 36 is advanced on the passage for temporarily stopping the first coin. It is also used to stop subsequent coins after a predetermined number of coins have passed. Also, the passage outlet bottom plate 1
A bottom plate supporting roller 38 is supported on the free end side of 8 via an arm 37. The roller 38 is placed on a flat plate 39 on the side of the machine body 2 and supports the free end side of the outlet bottom plate 18. There is. Further, at the outlet end of the outlet bottom plate 18, rollers 40, 40, 40 that guide the lower surface of the coin are mounted around.

It is possible to widen the passage width by moving to the left in FIG. Therefore, since the cam 25 has a circumferential surface whose radius changes steplessly, the passage width can be adjusted with one rotation angle of the pulse motor M ₁ as one pitch, and substantially stepless adjustment becomes possible. A coin having any outer diameter can be used as long as the outer diameter is within the range of the passage width and the minimum passage width.

With the movement of the movable passage member 17 to the left, the pin 28 serving as the fulcrum of the auxiliary passage member 27 also moves, and accordingly the passage surface 27a gradually moves.
The angle of 7 with respect to the edge portion 17b becomes large. Further, the movement of the movable passage member 17 causes the outlet bottom plate 18 to pivotally displace in the counterclockwise direction about the shaft 31 via the elongated hole 34 and the pin 32, and the auxiliary passage member 35 and the sensors S ₂ and S ₃ serve as the auxiliary members. The state of being parallel to the passage surface 27a of the passage member 27 is maintained. Therefore, as the width of the coin passage becomes wider, the angle of the passage formed by the auxiliary passage members 27 and 35 is displaced, and the ends of the auxiliary passage members move backward to approach the coin stacking portion 7 and enter the coin stacking portion 7 regardless of the coin diameter. The state does not change.

By the movement, the blocks 71 and 72 slightly move downward in FIG. 10, that is, in the direction away from the end of the coin passage 6, and as the diameter of the coin increases, the blocks 71 and 72 move away from each other and take a position suitable for receiving coins. Further, the rotation of the first link 83 causes the lever 9 to pass through the link 95.
4 is rotationally displaced in the clockwise direction about the shaft 84, and the closing member 93 at the tip thereof is retracted and is placed at a position commensurate with the increase in the distance between the belts 77 and 78. With these, belt 7
The inner diameter of the coin accumulating space formed by the 7, 78, the closing member 93, the guides 99, 100, etc. is continuously adjusted to a size that matches the set passage width, that is, the outer diameter of the coin.

With respect to the drive system of the coin stacking section 7, the arms 105,
Since 106 is connected to the member 112 by the shafts 109 and 110, the arms 105 and 106 are displaced in a direction in which they are straight, and follow the expansion between the belts 77 and 78, but the gears 107 and 108 are It is always in a meshed state,
Therefore, the driving force of the motor M ₄ is the gears 113, 103,
Left and right belts 77, 78 through 107, 108, 104
Is transmitted to the pulleys 74 and 76 of the belts 77 and 78 irrespective of the change in the interval of.

Since the coin wrapping unit 10 can handle any kind of coin by the conventional structure, the same structure as the conventional structure can be adopted.

The output signals of the coin insertion detecting sensor 3a and the coin inflow detecting sensor S ₄ are also input into the control unit 132.

Next, regarding the operation of the coin processing device according to the present embodiment, the flowchart shown in FIG. 16 and FIG.
This will be described with reference to the timing chart shown in FIG. Note that, here, a case will be described in which processing of coins and registration of denominations are performed simultaneously.

First, the key portion 115 is operated to specify the denomination setting mode (ST01 in FIG. 16). In this embodiment,
It is assumed that this mode is designated by sequentially pressing the keys "A", "F", and "ST" of the key section 115. The numerical values and the like input by the operation are displayed on the display units 122, 124 and the like.

Next, a denomination block is selected (FIG. 16).
ST02). For the selection of the denomination block, for example, all the denominations to be set in advance are written on the upper surface of the memory denomination display unit 123, and while looking at the denomination block, the down button 130 and the up button 131 are used to set the denomination to be set this time. This can be done by shifting until the seed is reached. If no denomination has been set, any block will do.

When the denomination block is selected, the denomination name and the number of packaging units are next entered using the keys of the key section 115 (ST03 in FIG. 16). At this time, the denomination display unit 124 displays the inputted denomination name. When the number of packaging units is not input, a preset default value may be adopted.

After that, using the mode switching button 117,
One of the “packaging mode” and the “counting mode” is selected (FIG. 16ST04). Here, the "packing mode" is a mode in which the processed coins are counted and packed. Also,
The “counting mode” is a mode in which only the processed coins are counted, and the coins are not wrapped by the coin wrapping unit 145 (see FIG. 15).

When the "counting mode" is selected, the outlet of the coin passage 6 is switched by a known method, a bag or the like is separately set in the outlet, and the processed coins are stored in the bag or the like after counting. On the other hand, when the "packaging mode" is selected, the input of the number of packaging units is also received. If the number of packaging units is not input at this time, the value stored in the storage unit 136 in advance is used.

It should be noted that at the same time when the power is turned on, one of the "packaging mode" and the "counting mode" may be automatically selected, and the mode setting may be changed only when the other mode is used. .

When the mode is set, the coin detection sensor 3a (see FIGS. 2 and 3) starts detecting coins (ST05 in FIG. 16). When the coin insertion detection sensor 3a detects that a coin has been inserted,
The driving of the rotating disks 4 and 5 is started (FIG. 16ST06, FIG. 17A). The driving of the rotary disks 4 and 5 may be started by a start switch.

Next, detection of coins by the unprocessed coin detection sensor 5a is started (ST07 in FIG. 16). When coins thrown on the rotary disc 4 are supplied on the rotary disc 5, the unprocessed coin detection sensor 5a detects the coins.

Then, it waits for a predetermined time (FIG. 16S).
T08). Here, this predetermined time is a time sufficient for the coins on the rotary disc 5 to reach the coin thickness regulating member 41 by the rotation of the rotary disc 5, and is determined by design conditions and the like.

When the above-mentioned predetermined time has elapsed, the motor M ₂ of the thickness adjusting unit 142 (see FIGS. 6 to 8) is driven (FIG. 17C), and only one pulse of the rotation angle detection sensor S ₇ is produced. Then, the thickness regulating member 41 and the conveyor belt 43 are raised (FIG. 16ST09). At this time, the fixed position sensor S ₆
Is turned off (light-shielded state) (FIG. 17D). And
When the coin inflow detection sensor S ₄ does not detect the coin, the operation of raising the thickness regulating member 41 and the conveyor belt 43 by one pulse until the coin is detected (ST0 in FIG. 16).
9) is repeated (FIG. 16ST10, FIG. 17B,
Area A in (e).

On the other hand, when the coin inflow detection sensor S ₄ detects a coin (FIG. 17B), it is determined that the coin has passed under the coin thickness regulating member 41, and the coin thickness regulating member 41 at this time. Storage unit 1 with the height of coins as "coin thickness information"
36 (see FIG. 15). Further, in order to allow a certain height, the thickness regulating member 41 and the conveyor belt 43 are further raised by a predetermined pulse (FIG. 16S).
T11, area B of FIG. 17 (e)). The number of pulses at this time is preset according to design conditions and the like.

Next, the movable passage member 17 is moved by driving the pulse motor M ₁ of the passage width adjusting portion 141 (see FIGS. 4 and 5) by one pulse to widen the passage width (FIG. 16 ST12, FIG. 16). 17 (f), (h) area C). At this time, the fixed position sensor S ₁ is off (light emitting state)
(FIG. 17 (g)). Then, the count sensor S ₂
When the coin is not detected, the operation of moving the movable passage member 17 by one pulse is repeated until the coin is detected (FIG. 16ST13, FIG. 17 (h), (i)).

On the other hand, when the count sensor S ₂ detects a coin (FIG. 17 (i)), it is determined that the coin has passed through the coin passage 6, and the passage width at this time is stored as "coin diameter information" in the storage unit. It is stored in 136 (see FIG. 15). Further, in order to allow the passage width to have a margin, the movable passage member 17 is moved further by a predetermined pulse to widen the passage width (region D in FIGS. 16ST14 and 17H). The number of pulses at this time is also preset according to design conditions and the like. At this time, the stopper 36 projects into the coin passage 6 and is in the other state, and stops the coins passing through the coin passage 6.

It is judged whether the selected mode is the counting mode or the packaging mode (ST15 in FIG. 16), and if it is the counting mode, the process jumps to step ST17. On the other hand, when in the packaging mode, the above-mentioned "coin thickness information"
And using "coin diameter information", calculate the following conditions
Settings are made (ST16 in FIG. 16).

According to the "coin thickness information", the coin collecting unit 7
The coin support part descending pattern of is determined. The coin support portion descending pattern is information that determines the drive pattern of the belts 77 and 78, that is, the descending pattern of the coin supporting portions 79 and 80 provided on the belts 77 and 78. The coin supporting portions 79 and 80 descend every time one coin is stacked, but the descending amount at this time is not always constant but changes according to a constant pattern. The coin support portion descending pattern is information representing the changing pattern of the descending amount at this time, and is determined according to the thickness of the coin, but the details are the same as those disclosed in Japanese Patent Publication No. 3-17704. .
The storage unit 136 (see FIG. 15) stores the thickness T of the coin.
It has a predetermined coin support part descending pattern according to (1) as a table, and the set coin thickness T
Read the one that corresponds to (1).

The inner diameter of the coin stacking section 7 is calculated and set using the "coin diameter information".

Different formulas are used according to the diameter of coins, and β ₁ <D (1) ≤ β ₂ and P ₃ = (C ₅ × D (1) −C ₆ ) +6 β ₂ <D (1) When ≦ β ₃ , P ₃ = (C ₅ × D (1) −C ₆ ) +5 When β ₃ <D (1) ≦ β ₄ , P ₃ = (C ₅ × D (1) −C ₆ ) +5・ ・ ・ ・ ・ ・ ・That is, (C ₅ × D (1) −C ₆ ), the diameter D
Various integers are added according to (1), and the result is P ₃ . Note that C ₅ , C ₆ and β ₁ , β ₂ , ... Have different values depending on the design values of the belts 77 and 78, respectively.

The "coin diameter information" is used for the timing of restarting counting of coins, the timing of starting the lowering of the coin support portions 79 and 80, the arrangement of the winding roller 9 (see FIG. 1), and the one-time packaging. It is also used to set the length of wrapping paper.

Upon completion of these calculations / settings, the calculation result is stored in the corresponding denomination block (storage area) in the storage unit 136 (FIG. 16 ST17). Even when the counting mode is selected, the inner diameter of the coin stacking unit 7 is calculated, and the calculation result is stored in the storage unit 136.
Shall be stored in.

Then, the stopper 36 is retracted (see FIG. 1).
6ST18). By executing the subroutine, the counting process is substantially started in the counting mode, and the counting process and the packaging process are substantially started in the packaging mode (ST1 in FIG. 16).
9).

In this processing, first, the coins reaching the end of the coin passage 6 are counted by the count sensor S ₂ , and the passage is confirmed by the sensor S ₃ . Here, when the number of coins in the packaging unit is counted by the count sensor S ₂ , the operation solenoid (not shown) of the stopper 36 is energized according to the signal, the stopper 36 advances into the coin passage 6, and thereafter. Stop the coins. Sensor S ₃
In the counting mode, the coins that have passed through are stored in a bag or the like from the switched passage outlet, and the processing ends when there are no more coins on the rotating disc. On the other hand, in the packaging mode, such coins are guided by the rollers 40, 40 ... And enter the coin stacking unit 7. In the coin stacking section 7, the support portions 79, 80 of the left and right belts 77, 78 are located near the upper ends, and the coins are placed across these support portions 79, 80. When one coin is placed on the supporting portions 79 and 80, the pulse motor M ₄
Rotates based on the signal from the sensor S ₃ by a predetermined pulse corresponding to the thickness of the coin. This allows the belts 77, 78
Is rotated, the supporting portions 79 and 80 descend as described above, and the processing ends when there are no coins on the rotating disk 5. The predetermined number of accumulated coins that have entered the coin accumulating section 7 are delivered to a supporting means (not shown) when the supporting sections 79 and 80 of the belts 77 and 78 move outward from the lower ends and are guided to the packaging section 10. The wrapping paper 8 is wrapped, and the wrapped coins are ejected from the outlet 11.

Upon completion of such processing, the output signal of the unprocessed coin detecting sensor 5a is confirmed, and if there is a coin, the processing by the above-mentioned subroutine (ST19 in FIG. 16) is repeated. On the other hand, if the unprocessed coin detection sensor 5a does not detect coins for a predetermined period of time, it is determined that there are no coins (ST20 in FIG. 16).

When the coins are exhausted, if there are other denomination blocks for which denomination registration is to be performed, ST02 and subsequent steps are repeated (ST21 in FIG. 16). If not, the keys "E" and "ST" are sequentially pressed. By doing so, an end instruction is given (ST22 in the figure).

When the stop button 129 is pressed while coins remain on the rotating discs 4, 5, etc., the coin thickness regulating member 41 and the passage width adjusting part 141 are rotated without returning to the initial state. The rotation of the disks 4 and 5 is stopped. Thereby, when the same coin is continuously processed, the height adjustment of the coin thickness regulating member 41 and the passage width adjustment unit 1 are performed.
Because it is not necessary to redo the passage width adjustment of 41 from the beginning,
The processing efficiency can be improved. Further, when it is desired to return the coin thickness regulating member 41 and the passage width adjusting portion 141 to the initial state after pressing the stop button 129 to stop the apparatus, the clear button 127 is pressed.

Although the most preferred embodiment has been described above as the present embodiment, the design change is arbitrary within the scope not departing from the technical idea of the present invention.

For example, in the present embodiment, the denomination block is first designated and the denomination name is input before the processing of coins is started (ST02, ST03 in FIG. 16), but the denomination is processed after the coin processing. The block may be designated.

In this embodiment, the case where the coin processing and the measurement / calculation / storage of the denomination information are performed at the same time has been described, but when only the denomination information is registered, only one coin is inserted. However, the normal coin processing may not be performed. In this case, since the coins are not processed, the number of packaging units and the setting / determination of the mode (FIG. 16 ST03, ST
04, ST15) is not performed. After registering such denomination information, coin processing can be performed by designating a denomination as in the conventional coin processing machine.

Further, in this embodiment, the motors M ₁ ,
A pulse motor is used as M ₃ and M ₄ , and a motor M ₂
Although a DC motor was used as the motor, the motors M ₁ , M ₃ ,
A DC motor may be used as M ₄ , or a motor M ₂
You may use a pulse motor as. However, when a DC motor is used instead of the pulse motor, a mechanism for detecting the rotation angle is required.

In addition to the above-mentioned information, the storage unit 136 may store other information such as the power supply frequency.

Further, as the storage unit 136, EEPR
In addition to the OM, a RAM having a battery backup may be used.

In addition, each information is EEPRO at the time of adjustment.
Instead of reading from M, all information may be read once from the EEPROM and stored in the RAM when the power is turned on and the settings are stored, and each information may be read from this RAM at the time of adjustment.

[0096]

As described above, according to the present invention,
Since the passage width and passage height of the coin passage that conveys coins can be automatically detected and set as denomination information, and these values can be stored, the processed coins can be stored. It becomes unnecessary to research and input the denomination information of.
