Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin wrapping machine for stacking coins in a predetermined number and packaging the stacked coins.

[0002]

2. Description of the Related Art A coin supplied through a coin passage is supported from below in a state in which the front side is inclined so that the front side is located at an upper side, and the coin is pushed out by a preset fall amount for each number of coins to be pushed out. 2. Description of the Related Art As a conventional coin wrapping machine having a shelf part that is lowered together with the coins to sequentially stack and stack the coins, for example, Japanese Patent Laid-Open No. 2-1.
There are those described in Japanese Laid-Open Patent Application No. 66023 or Japanese Laid-Open Patent Publication No. 62-208329. In this type of conventional coin wrapping machine, the set drop amount of the shelves according to the count value (the number of stacked coins) of accumulated coins is set and stored at the time of manufacture for each denomination, and the counting unit is on the shelf. When the number of coins accumulated in is counted, a set fall amount corresponding to the counted value is read out, and the pulse motor for raising and lowering the shelves is driven and controlled based on the set fall amount.

[0003]

However, the coins actually packaged by the coin wrapping machine include new coins that have just been circulated and coins that have been circulated for a long time and whose front and back surfaces are worn away. These thicknesses are subtly different even for the same denomination, so if the shelves are lowered based on the set drop amount set and stored at the time of manufacturing as in the above-mentioned conventional technique, it may be different depending on the state of use or environment. The height position of the top of the accumulated coins accumulated on the shelves may deviate significantly from the position assumed for setting the set drop amount, which increases the incidence of jams. There was something that happened. In addition, for coin wrapping machines where the incidence of jams has increased in this way, in order to reduce this incidence, the environment in which the coin wrapping machine is used or the usage situation is separately investigated, and the shelves are set. It is necessary to recreate the amount of drop separately and store it in the coin wrapping machine, and if an attempt is made to perform such separate investigation and recreate the set drop amount for each coin wrapping machine. Will take a great deal of time and effort. Therefore, an object of the present invention is to provide a coin wrapping machine that can easily set an optimal set drop amount according to the environment in which it is used or the state of use.

[0004]

In order to achieve the above object, a coin wrapping machine according to claim 1 of the present invention provides a coin passage for guiding coins, and a coin passage arranged above the coin passage along the coin passage. And a conveyor belt for moving coins, and coins pushed out one by one from the end portion of the coin passage by the conveyor belt are supported from below in a state of being inclined so that the front side is located above, and each of the coins pushed out. A shelf portion for dropping and stacking coins one by one with a predetermined set-down amount set for each number of coins, and a stacking portion for sequentially stacking and placing coins in the vertical direction; A front regulation member that abuts and regulates the movement of the container, and a wrapping unit that wraps the wrapping paper around the stacking coins stacked in the wrapping unit to wrap the wrapping paper, and the shelf unit or the shelf unit. To A coin that is pushed out by the conveyor belt on the held coin is made contactable at the upper end position thereof, and contact detection means capable of detecting contact and non-contact of the coin, and supported on the shelf or the shelf. From the timing at which the coin pushed out by the conveyor belt is continuously pushed on the coin by the conveyor belt, the coin pushed out by the conveyor belt is changed from the state in which the coin contacts the contact detection means to the non-contact state. When a predetermined number of coins are used for the drop amount detection operation for detecting the drop amount data of the shelves from the state of contacting the contact detecting means to the non-contact state while being continuously pushed by the conveyor belt. It is sequentially performed until it is accumulated on the shelves, and a descent amount setting process is performed to set the set descent amount for each of the coins pushed out by the conveyor belt from each descent amount data. It is characterized by comprising the Nau drop setting means. Thereby, the descent amount setting means is in contact with the contact detection means in a state where the coin pushed out by the conveyor belt onto the shelf portion or the coin supported by the shelf portion is continuously pressed by the conveyor belt. Descent amount data of the shelf from the timing of switching to the state to the timing of switching to the non-contact state from the state in which the coin pushed out by the transport belt continues to be pushed by the transport belt The descending amount detection operation for detecting the number of coins is sequentially performed until a predetermined number of coins are accumulated on the shelf, and the set amount of falling on the shelf for each number of coins pushed out by the conveyor belt from each amount of falling data is set. Perform the setting process. In this way, since the set drop amount is set from the actual drop amount data of the shelves accompanying coin accumulation, it is possible to easily set the optimum set drop amount according to the environment in which the coin is used or the usage situation. .

The coin wrapping machine according to claim 2 of the present invention is the coin wrapping machine according to claim 1, wherein the descent amount setting means is set to the descent amount data detected by the new descent amount setting processing and is set up to then. It is characterized in that a new set drop amount is obtained by averaging the set drop amount. In this way, the average of the fall amount data detected in the new fall amount setting process and the set fall amount set up to that point is set as the new set fall amount, so that the new set fall amount is set. Therefore, when only the used coins are extremely different from other coins, it is possible to prevent the drop amount data from changing extremely.

The coin wrapping machine according to claim 3 of the present invention is the coin wrapping machine according to claim 1, wherein the descent amount setting means stores descent amount data detected in the latest descent amount setting processing up to a plurality of times. In addition, it is characterized in that the averaged amount of each of these drop amount data is used as the set drop amount. In this way, the averaged amount of drop data detected in the latest multiple sets of drop amount is used as the set drop amount, so only the coins used for setting the new set drop amount are extremely different. When it is different from the coin,
It is possible to prevent the drop amount data from changing extremely.

A support arm 41, to which the support post 38 is fixed, is provided on the upper side of the tip, and a cam motor 42 (see FIG. 3) for moving the support arm 41 up and down. Then, the support post moving mechanism 39 moves the support arm 41 to the support shaft 40 while the accumulated coins are transferred to the support post 38.
The coins are accumulated along the accumulating portion 14 by lowering the accumulated coins.
From the sheet to the packaging unit 17.

As shown in FIG. 1, the packaging unit 17 is disposed below the stacking unit 14, and supplies the wrapping paper 16 around the stacking coins supported by the support posts 38 located at the packing position. It is provided with a wrapping mechanism 44 that winds and wraps it, and a crimping mechanism 45 that crimps the wrapped wrapping paper 16 at the upper and lower edges of the accumulated coins.

The packaging mechanism 44 includes a support post moving mechanism 39.
Operation, the plurality of, for example, three parallel wrapping rollers 46, 46, 4 for moving the stacking unit 14 to the wrapping unit 17 and sandwiching the stacked coins located at the wrapping position from the radial direction.

It is possible to approach and separate in the direction.

The denomination type position setting mechanism section 19 determines the distance between the guide bodies 21b of the coin transporting section 12, that is, the width of the passage surface 21a and the distance between the accumulating drums 28, 28 of the accumulating section 14 by selecting the denomination by the operating section 9. The distance is adjusted according to the outer diameter of the coin of the denomination.

Further, in this embodiment, as shown in FIG.
As shown in FIG. 3, the display unit 8, the operation unit 9, the rotary disc 20, the position setting mechanism unit 19 for each type of gold, the conveyor belt 22, the pulse motor 31, the stopper 15, the shutter solenoid 3 as described above.
7, the sensors 13a and 13b, the continuity detection unit 35, the reference position detection sensor 32, the wrapping paper supply roller 47, and the cam motor 42 are connected to a CPU (falling amount setting means) 51 that controls the operations of these, and the like. In addition to these, the CPU 51 stores a control program for the coin wrapping machine, the coin C, and reference data for each denomination of the accumulated coins, and the like.
The M52 is connected to the RAM 53 that stores data and the like detected by the sensors 13a and 13b.

The process for setting the amount of lowering of the protrusions 27, 27 of the coin wrapping machine according to this embodiment having the above-described structure will be described below with reference to the flow chart shown in FIG. First, an operator inserts a coin of a denomination for which drop amount data is to be taken in through a coin insertion opening (not shown) provided on the rotary disc 20 above the rotary disc 20, and sets a set drop amount on the operation unit 9. A setting mode for selecting is selected and a denomination is selected.

Then, the CPU 5 receives signals output from the operating section 9 in response to these operations on the operating section 9.
1 drives the denomination type position setting mechanism section 19 based on the data stored in the ROM 52, and the coin C of the selected denomination is selected.
To the outer diameter of the coin passage 21 and the collecting drum 28,
28, the pulse motor 31 is adjusted based on the data stored in the ROM 52.
It is driven until the reference position detection sensor 32 detects that 7 and 27 have been moved to a preset reference position common to all denominations. Here, at the reference position, the protrusions 27, 27 surely support one coin C regardless of the denomination, and the upper end of the coin C is surely contacted with the contact surface 34a of the conduction detecting piece 34. It is a position where they are brought into contact with each other and reliably separated from the front regulation plate 25.

Next, when the operator performs a start operation for starting the set descent amount operation on the operation section 9 and a signal accompanying this is output from the operation section 9, the CPU 51 receives this and the rotating disk. 20 and the conveyor belt 22 are driven. Due to the centrifugal force due to the rotation of the rotating disk 20,
The coins C are fed while being separated one by one by a guide member into the coin passage 21 of the coin transport unit 12 provided on the peripheral portion of the rotary disc 20.

Then, the coin C sent to the coin passage 21
Is detected by the upstream sensor 13a while being conveyed through the coin passage 21 by the conveyor belt 22 arranged above the coin passage 21. Then, the CPU 51 drives the stopper 15 at a timing when the first coin C passes through the stopper 15 after being detected by the sensor 13a and the second coin C does not exceed the stopper 15, and closes it. The coins C after the first coin are stopped. In this way, only one coin is sent to the stacking unit 14 (step SP1).

On the other hand, the first coin C is transferred to the coin passage 21 by the conveyor belt 22 arranged above the coin passage 21.
While being conveyed, it is detected by the sensor 13b. The CPU 51 counts the coins C by the detection by the sensor 13b (step SP2). Then, the first coin C
Is pushed by the conveyor belt 22 from the terminal end of the coin passage 21 onto the protrusions 27, 27 and supported by these protrusions 27, 27, and further, the pushed-out coin C is continuously pushed by the conveyor belt 22. Then, it moves along the protrusions 27, 27 and comes into contact with the contact surface 34a of the continuity detecting piece 34 to bring it into a conductive state and stop (state shown in FIG. 4). When the contact between the conduction detecting piece 34 and the coin C is detected in the conducting state (step SP3), the CPU 51 turns the pulse motor 31 on.
N, that is, the driving is performed to rotate the collecting drums 28, 28 to lower the protrusions 27, 27 (step SP4).

Then, the protrusions 27, 27 and the continuity detecting piece 3
4, the coin C is moved to the front regulation plate 25 side on the protrusions 27, 27 by the driving force of the conveyor belt 22 while contacting the contact surface 34a of the conduction detecting piece 34, As a result, it comes into contact with the front regulation plate 25 and then separates from the conduction detecting piece 34 (the state shown in FIG. 5). And
The CPU 51 stops the pulse motor 31 at the timing when the coin C is switched from the contact state to the non-contact state with respect to the conduction detection piece 34, that is, the timing when the conduction detection piece 34 is switched from conduction to conduction interruption (step SP5). Step SP6). Next, the CPU 51 returns to step SP1 because the coin C is the first one (step SP7). This is, in this embodiment,
The reference position is common to coins of all denominations having different thicknesses, and therefore, the drop amount data for the first coin does not correspond to the coin C, and is not used.

Next, the CPU 51 opens the stopper 15 so that the second coin C passes through the stopper 15 after being detected by the sensor 13a and the third coin C does not exceed the stopper 15 at a timing. To close the coins C and stop the third and subsequent coins C (step SP
1).

On the other hand, the second coin C is transferred to the coin passage 21 by the conveyor belt 22 arranged above the coin passage 21.
While being conveyed, it is detected by the sensor 13b. Then, the CPU 51 counts the coins C (step S
P2). Subsequently, the second coin C is pushed by the conveyor belt 22 from the terminal end of the coin passage 21 onto the first coin C supported by the protrusions 27, 27, and is supported by the coin C. , The pushed second coin C continues to be pushed by the conveyor belt 22 and moves along the first coin C to come into contact with the contact surface 34a of the continuity detecting piece 34 and stop it in the conductive state. (State shown in FIG. 6). When the contact between the continuity detecting piece 34 and the coin C is detected (step SP
3), the CPU 51 turns on the pulse motor 31, that is, drives the pulse motor 31 to rotate the accumulation drums 28, 28, and the protrusions 27,
27 is lowered (step SP4).

Then, the gap between the first coin C supported by the projections 27, 27 and the continuity detecting piece 34 gradually widens, so that the second coin C is driven by the driving force of the conveyor belt 22. After being moved to the front regulation plate 25 side on the first coin C and abutting on the front regulation plate 25, the coin C is separated from the conduction detecting piece 34 (state shown in FIG. 7). Then, the CPU 51 switches the contact state of the second coin C to the non-contact state of the conduction detecting piece 34, that is, the timing of switching of the conduction detecting piece 34 from the conducting state to the non-conducting state (step SP5).
The pulse motor 31 is stopped (step SP6).

Next, since the coin C is not the first coin C (step SP7), the CPU 51 drives the pulse motor 31 at this time (step SP).
4) until the drive is stopped (step SP6), that is, the protrusion 27 for the second coin C,
The descending amount data of 27 is obtained by the number of pulses from the pulse motor 31, and this is stored in the RAM 53 as the set descending amount of the protrusions 27, 27 for the first coin C of the denomination (step SP8). Similarly, the third coin C is sent out onto the protrusions 27, 27, and the third coin C
Indicates the number of pulses (falling amount data) between ON and OFF of the pulse motor 31 when the contact detection piece 34 is switched from contact to non-contact with the protrusion 27 for the second coin C of the denomination. RAM 53 as the set drop amount of 27
The coins C are sequentially stored in the protrusion 2
The accumulated drop amounts for each number of sheets are stored in the RAM 53 while being accumulated in 7, 27. And sensor 1
When the count value of 3a reaches the number of stacked sheets in a packaging unit, that is, the number of packages (step SP9), the descent amount setting processing operation ends at the timing when the last coin is stacked. The accumulated coins thus accumulated by the number of packages are sent to the packaging unit 17 and subjected to the packaging process in the same manner as described later.

In addition, after the last coins in the stacking number are counted in the packing operation, the stacking coins are dropped to be transferred to the shutter 29. Therefore, the value obtained by the above-described drop amount setting processing operation becomes the set drop amount for each number of sheets in the packaging unit as it is. Then, if necessary, the above-described descent amount setting process is performed for the coins C of all denominations.

Next, the wrapping operation of the coin wrapping machine according to this embodiment will be described below. When the coin wrapping machine according to the present embodiment is used to wrap the coin C, first, the denomination in which the operator wraps the coin C through the coin insertion slot (not shown) provided on the rotary disc 20. The coin C is inserted, and the operation section 9 selects the setting mode for packaging and selects the denomination. Then, the operation unit 9
In response to the signals output from the operation unit 9 in response to these operations in, the CPU 51 drives the denomination type position setting mechanism unit 19 based on the data stored in the ROM 52,
The outer diameter of the coin C of the selected denomination is adjusted to match the passage width of the coin passage 21 and the interval between the stacking drums 28, 28, and the pulse motor 31 is driven to stack the protrusions 27, 27 on top of the coins. And the continuity detecting piece 34 are moved to a position where a predetermined gap is generated. This prevents jamming when the coins C are accumulated in the accumulating unit 14 because the distance between the uppermost coin accumulated in the accumulating unit 14 and the continuity detecting piece 14 becomes narrower than necessary. This is because the top of the accumulated coins and the continuity detecting piece 34
To move to a position where there is a margin between and, drive the pulse motor 31 by a predetermined number of pulses from the reference position,
The protrusions 27, 27 may be lowered. Then, by inputting the start of the packaging operation on the operation unit 9, C
The PU 51 drives the rotating disk 20 and the conveyor belt 22. Due to the centrifugal force generated by the rotation of the rotary disc 20, the coins C are fed out into the coin passage 21 of the coin transport unit 12 provided at the peripheral portion of the rotary disc 20 while being separated one by one by the guide member.

The coin C sent to the coin passage 21 is discriminated when passing through the sensor 13a while being conveyed through the coin passage 21 by the conveyor belt 22 arranged above the coin passage 21, and should be packaged. Only the coin C of the denomination is guided to the sensor 13b along the coin passage 21. Then, the CPU 51 performs counting every time the coin C is detected by the sensor 13a, and when the counted value reaches a preset number, activates the stopper 15 to close the coin passage 21. Therefore, a predetermined number of coins C that have passed through the stopper 15 before the stopper 15 is closed.
Are sent to the stacking unit 14 arranged on the most downstream side of the coin passage 21.

In the stacking unit 14, the coins C sent from the coin passage 21 are transferred to the projecting portions 27 of the stacking drums 28, 28.
27 on top of each other. At this time, the CPU 51
When the supplied first coin C is detected by the sensor 13b and is then fed onto the protrusions 27, 27, the pulse motor 31 is moved so as to lower the protrusions 27, 27 by a set drop amount with respect to the first coin. And the second coin C supplied subsequently is detected by the sensor 13b and then the protrusion 2
The second coin C at the timing when it is rolled up to 7,27
By repeating the operation of rotating the pulse motor 31 so as to lower the protrusions 27, 27 by the set lowering amount for the stacking drums 28, 28.
A plurality of coins C are vertically stacked and stacked between the front and rear regulation plates 24 and 25 to form a stacked coin.

Then, the protrusion 2 of the collecting drum 28, 28
The accumulated coins supported by the protrusions 27, 27 and lowered by the rotation of 7, 27 are delivered to the shutter 29 when the protrusions 27, 27 are separated from the accumulated coins. On the other hand, the coin passage 21
When the counting of the predetermined number of coins C in
The PU 51 drives the cam motor 42 to drive the coin moving unit 18
The operation of the support post moving mechanism 39 is started. As a result, the support post 38 of the coin moving unit 18 is disposed between the packaging rollers 46, 46, 46 and at the standby position immediately below the shutter 29.

When the support post 38 is located at the standby position in this way, the CPU 51 drives the shutter solenoid 37 to open the shutter 29 to open the support post 38 on condition that the accumulated coins have been transferred onto the shutter 29. Move the accumulated coins to the top. Then, the CPU 51 lowers the support arm 41 of the coin moving unit 18 along the support shaft 40 to lower the support posts 38 and the accumulated coins supported by the support posts 38 at the standby position to move the coins downward from the accumulating unit 14. It is conveyed to the packaging position which reaches the packaging section 17.

When the accumulated coins are placed in the packaging position, CP
The U 51 causes the three packaging rollers 46 to simultaneously approach toward the peripheral surface of the accumulated coins by the operation of the cam motor 42. At this time, at the same time, the wrapping paper supply roller 47 is driven to rotate so that the front end of the wrapping paper 16 and the wrapping rollers 46,
46, 46, and finally, by these three wrapping rollers 46, 46, 46, the wrapping paper 16 is inserted between them.
The accumulated coins are clamped from the outside in the radial direction while sandwiching.

From this state, the packaging rollers 46, 46, 46
To rotate. As a result, the wrapping paper supply roller 47
Then, the wrapping paper 16 that has been fed out by an appropriate length and cut by the cutter 48 is wound around the peripheral surface of the accumulated coins. After the wrapping paper 16 is wound around the peripheral surface of the accumulated coins in this way,
The wrapping rollers 46, 46, 46 are rotated at a faster speed than the wrapping paper 16 is wound around the peripheral surface of the coins, while the cam motor 42 is actuated to swage the claws 49, 49.
Is brought close to both end faces of the accumulated coin, and both ends of the wrapping paper 16 are caulked.

As described above, after the wrapping paper 16 is wound around the peripheral surface of the accumulated coins and the packaging coins are formed by crimping both ends of the wrapping paper 16, the packaging coins are clamped. The wrapping rollers 46, 46, 46 that have been used are separated from each other, and the wrapping coins are discharged to a roll chute (not shown) arranged below the wrapping section 17.

As described above, according to this embodiment, the CPU 51 causes the projections 27, 27 or the projection 2 to be formed.
The timing at which the coin C pushed out by the conveyor belt 22 on the coins C supported by 7, 27 is switched from the state of contacting the continuity detecting piece 34 to the state of non-contact while being continuously pushed by the conveyor belt 22 (Fig. 5), the timing at which the coin C pushed out next by the conveyor belt 22 switches from the state of contacting the continuity detecting piece 34 to the state of non-contact while being continuously pushed by the conveyor belt 22 (see FIG. 7). The descending amount detection operation of detecting the descending amount data of the protrusions 27, 27 up to the timing (shown) is sequentially performed until a predetermined number of coins C are accumulated on the protruding portions 27, 27, and the conveying belt 22 uses the respective descending amount data. The above-described descent amount setting process for setting the set descent amount of the protrusions 27, 27 for each number of the pushed-out coins C is performed. As described above, since the set drop amount is set from the actual drop amount data of the protrusions 27, 27 due to the coin accumulation, it is possible to easily set the optimum set drop amount according to the environment or the usage situation. It will be possible. Moreover, since the coins accumulated for setting the set drop amount can be directly packaged in the packaging unit 17,
The accumulation operation is not wasted.

It should be noted that even if the situation or environment in which the coin wrapping machine is used is changed later, it is possible to cope with this, even after the set descent amount is set at the beginning, if necessary. The descent amount setting process may be performed. In such a case, the CPU 5
1 indicates that the fall amount data detected by the new fall amount setting process is used as the set fall amount as it is, and the fall amount data detected by the new fall amount setting process and the set fall amount set up to that point. It is also possible to set an average of and as a new set drop amount (Note that if the set drop amount has not been set before, the newly detected drop amount data will be used as is. It becomes.). In this way, if the fall amount data detected in the new fall amount setting process and the set fall amount set up to that point are averaged and this is set as the new set fall amount, the new fall amount setting process is performed. It is possible to prevent the drop amount data from changing extremely when, for example, only the coins used in 1. are extremely different from other coins.

Further, the CPU 51 is made to store in the RAM 53 the drop amount data detected in the drop amount setting processing from a new one to a plurality of times (for example, three times), and average the respective fall amount data thus stored. It is also possible to set what was done as the set amount of fall. In this way, if the data obtained by averaging the drop amount data detected by the new, new to multiple (for example, three times) drop amount setting processing is set as the set drop amount, the setting of the new set drop amount can be changed. Therefore, when only the used coin is extremely different from other coins, it is possible to further prevent the drop amount data from changing extremely.

In addition, when the packaging process is performed in the state where the set descent amount is not set at all, the CPU 51 automatically sets the descent amount described above regarding the stacking operation accompanying the first packaging process without any special operation input. The processing may be performed, and the packaging processing may be continuously performed based on the set drop amount set in the drop amount setting process. Further, when the packaging processing is performed a preset number of times, if the above-described descending amount setting processing is automatically performed for the stacking operation associated with the next packaging processing, the descending amount setting processing is performed regularly. As a result, a more stable set descent amount can be obtained, and when the environment in which it is used changes, this can be automatically dealt with. In addition, when the power supply in the OFF state is turned ON, the above-described descent amount setting process is automatically performed for the stacking operation associated with the first packaging process, and when the environment in which it is used is changed, it is automatically performed immediately. This can be accommodated. It should be noted that it is also possible to perform these automatic descent amount setting processes a plurality of times to average the descent amount data and set the set descent amount. In this case, the number of descent amount setting processes is set by the operation unit 9. It suffices to be able to set it once.
