Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a coin wrapping machine, and more particularly to a coin wrapping machine that has a function of wrapping a predetermined number of piled coins with wrapping paper and counting the correctly wrapped coins. Regarding packaging machines.

[Conventional technology]

As a conventionally known coin wrapping machine, there is one described in Japanese Utility Model Application Publication No. 166706/1985, which was previously proposed by the applicant of the present application. With this coin wrapping machine,
A switching member is provided in the path through which the wrapped coins pass, and the switching member is used to sort the normally wrapped coins and the abnormally wrapped coins.
This ensures that only properly packaged coins are obtained.

Further, as an apparatus for counting wrapped coins, there is a coin wrapping machine described in Japanese Utility Model Application Publication No. 55-67561. This is done by providing a detection switch on the path of the packaged coins to detect the passage of the packaged coins, and by counting the number of times the detection switch detects the number of times the packaged coins are detected.

In order to count only normally wrapped coins using the conventional technology, a branching point with a switching member is provided in the middle of the path through which the wrapped coins pass, and this is used to distinguish between the path through which normally wrapped coins pass and the path through which abnormally wrapped coins pass. It is conceivable to branch the passage into two passages through which packaged coins pass, and further provide a detection switch on the branch passage through which only normal coins pass.

[Problem to be solved by the invention]

However, in this case, a switching member is provided on the passage to branch one passage into two passages, so in order to perform smooth switching, at least the switching position where the switching member is present must be widened to some extent. It is necessary to widen the branch passage accordingly. This is because if the passage is left narrow, it will become clogged. As a result of having such a wide passageway, there was a problem in that in order to reliably detect passage through the passageway, it was necessary to install multiple sensors or to pay considerable attention to the placement of the sensors. .

The present invention has been made in view of such problems, and an object of the present invention is to provide a coin packaging machine that can reliably count normally wrapped coins with a small number of sensors.

[Means to solve the problem]

According to the coin wrapping machine of the present invention, the stacked coin wrapping unit stacks a predetermined number of coins to be wrapped and wraps the stacked coins by wrapping wrapping paper on both sides of the stacked coins; A chute switching member provided at the bottom for separately discharging abnormal coins and normally wrapped coins that occur between the end of the coin stacking operation and the end of the wrapping operation, and a chute for switching the chute switching member. a switching drive unit, and a shoot switching drive control means that normally positions the shoot switching member on the side that discharges abnormal coins, and temporarily switches the shoot switching member to the side that discharges normally packaged coins only when discharging normal coins. , a chute switching detection means that detects when the chute switching member switches to a side for discharging normally wrapped coins and generates a detection signal; and a counting means that counts the detection signals from the chute switching detection means; A packaging number memory that stores the counted value counted by the counting means, a packaging number setting memory that presets and stores the number of packaging to be packaged, and the contents of the packaging number memory and the packaging number setting memory are the same. The present invention is characterized by comprising a match determining means for determining whether or not a match is found, and a wrapping operation stopping means for stopping the wrapping operation when the match determining means detects a match.

[Effect]

According to the coin packaging machine according to the present invention, the switching member provided in the branch passage is normally at a position where abnormal coins are ejected, and is switched to the normal coin ejection side only when normal coins are ejected. This switching is detected by a sensor, and the count of this detection signal becomes the count of normally wrapped coins. That is, since the detection of switching confirmation and the counting of normal coins are shared, there is no need to provide sensors on the passage, and reliable counting is possible without increasing the number of sensors.

[Embodiments of the invention]

The present invention will be explained below with reference to embodiments shown in the drawings.

FIG. 1 shows a schematic structure of a coin wrapping machine. In the figure, reference numeral 1 denotes a coin detection unit that detects coins X continuously ejected from a rotating disk 2 by optical means or the like. A detection signal A is output for each coin X ejected by the coin detection section 1. A stop piece 3 is driven by a stop solenoid 26 to forcibly stop the conveyance of coins in order to interrupt the feeding of coins when a predetermined number of coins have been counted. 4 is a device that is counted by the coin detection unit 1, and allows the sent coins to fall and be stacked in a horizontal manner, and is formed of a cylindrical body that is open at the top and bottom and has an inner diameter that matches the diameter of the coins. It is a coin stack cylinder. 5, 5 is a shutter provided at the bottom opening of the coin stacking tube 4, and is forcibly closed by a spring or the like so that the coins dropped into the coin stacking tube 4 are stacked on the shutter 5. It will be done. Reference numeral 6 denotes a shutter drive solenoid which opens the shutter 5 to the left and right by inputting an opening signal F when a predetermined number of coins 2 are stacked in the coin stacking cylinder 4. It should be noted that even when a stacking phenomenon occurs in the coin stacking tube 4, an opening signal F is given to open the opening/closing plates 5, 5 to the left and right. Numeral 7 is a wrapping paper for wrapping a predetermined number of stacked coins, and is supplied by a feeding motor (not shown) of a wrapping drive section 23, which will be described later. 8, 8, 8
is a packaging roller that wraps a predetermined number of coins stacked in the coin stacking tube 4 by wrapping the wrapping paper 7 around the coins by a wrapping roller drive motor (not shown) of the packaging drive unit 23. 9 places the stacked coins in the coin stacking tube 4 on the upper surface and descends from the coin stacking tube 4 at a low speed while reducing the impact to prevent the stacked coins from collapsing. The coin guide is lowered by a coin guide motor (not shown) of the wrapping drive section 23 at a predetermined timing until the center of the height of the coin and the center of the width of the wrapping paper 7 substantially match. Reference numerals 10 and 10 designate winding needles that wrap the coins by winding up the upper and lower edges of the wrapping paper 7, which is wound around the stacked coins by the wrapping rollers 8, 8, 8, at a predetermined timing. Reference numeral 11 denotes a guide chute for allowing the wrapped coins or abnormal coins wrapped by the winding needles 10, 10 to fall naturally and be discharged. Reference numeral 12 is a packaged coin discharge port through which packaged coins are discharged. 13
is a chute switching member that separately discharges normal coins and abnormal coins that fall into the guide chute 11 and are discharged. 14 is a chute switching member 13
The chute switching member 13 is switched to the abnormal coin ejection side by a means such as a spring at least from the time when the shutter 5 starts to open until the end of the wrapping operation, and the normal coins are ejected. In this case, the chute switching member 13 is switched to the normal coin ejection side by the switching control signal I as one of the wrapping operation cycles. Reference numeral 15 denotes a normal coin accommodating portion for storing normally packaged normal coins. Reference numeral 16 denotes an abnormal coin storage section for storing abnormal coins such as fallen coins, other coins with bad stacking, and coins with bad wrapping. 1
Reference numeral 7 denotes a cylinder standing detection means that detects when a predetermined number of coins have been counted by means of electrodes provided at a predetermined height position in the coin stacking cylinder on the opening/closing plates 5, 5 with opposite poles. It is designed to detect when coins are stacked higher than the stacked height of coins. Then, the cylinder standing signal B is outputted by the detection. Note that a photoelectric element may be used in place of the above electrode, and if the detection rod is thrust into the coin stacking tube 4 and there is a tube stand, the tip of the detection rod will hit the tube stand coin and cannot be moved. It may also be detected. 18, the wrapping paper 7 is normally wrapped in the wrapping rolls 8, 8,
Wrapping paper shortage detection means detects by a micro switch whether or not the packaging paper has been sent to the wrapping paper shortage signal C and outputs a wrapping paper shortage signal C. 19, when the winding needles 10, 10 wind up the upper and lower lines of the wrapping paper 7, if the number of stacked coins is small, the upper winding needles 10, 10 lower by more than a predetermined range, and a micro switch is activated. Detects the number of sheets and outputs a sheet count shortage signal D. 20 inputs the cylinder stand signal B from the cylinder stand detection means 17 to input the abnormal signal G1, and inputs the wrapping paper shortage signal C from the wrapping paper shortage detection means 18 and the number shortage signal D from the number shortage detection means 19. This is an abnormality detection section that outputs an abnormality signal G2. In addition, when the packaged coin discharge port 12 is clogged with packaged coins, or when the normal coin storage section 15 and the packaged coin discharge port 12 are filled with packaged coins, the switching member 13 hits the packaged coin and it becomes completely abnormal. If it is not switched to the coin ejection side, the detection means 2
4 detects this and gives a signal T to the abnormality detection section 20 and the packaging control section 23. When the abnormality detection section 20 receives the signal T, it outputs an abnormality signal G3 if the signal T is not in the switching state. Although this detection means 24 is shown as having a configuration in which a micro switch is operated by a protrusion of a cam plate 25 that rotates following the switching drive of the switching member 13, the cam plate 25 is not limited to this configuration. Instead, the light from the photoelectric element may be detected by blocking the light from the photoelectric element with a shielding plate. Further, a case where the switching member 13 cannot be switched due to a coin being stuck in the gap between the switching member 13 and the output chute 11 is similarly detected.

Reference numeral 23 denotes a packaging control unit which, when the abnormality signal G1 is input, operates the shutter drive solenoid 6 to open the shutter 5, drops the stacked abnormal coins that stand up, and removes the abnormal coins by the chute switching member 13. It is housed in the housing section 16. Furthermore, when the abnormality signal G2 is input, the switching signal I is not outputted, and the chute switching member 13 at this time
remains switched to the abnormal coin ejection side. When the packaging control unit 23 further inputs a start signal K from the operation instruction input unit 27 to start packaging,
The coin wrapping mechanism is operated at predetermined timings by motors and solenoid drive means (not shown). The packaging control unit 23 also outputs a release signal F to operate the shutter drive solenoid 6 to open the shutters 5, 5, and then the stacked coins are moved by the coin guide 9 to packaging rollers 8, 8, 8. When the shutters are lowered to the position, the shutter drive solenoid 6 is de-energized and the shutters 5 are closed again. At the same time, the counting of the number of wrapped coins is reset and the stacking operation of coins is started again. When the wrapping paper 7 is wound around the stacked coins by the wrapping rollers 8, 8, and the wrapping operation is completed, the chute switching control section 22 is activated unless the abnormal signals G1 and G2 are input. The chute switching drive section 14 outputs the switching signal I via the
is activated to switch the chute switching member 13 to the normal coin ejection side, and after a predetermined time has elapsed or after confirming that the normal coins have been collected by the normal coin collecting section 15, the chute switching drive section 14 is deactivated to switch the chute. The member 13 is returned to the abnormal coin ejection side.
Further, when the abnormality signal G3 is input, the coin wrapping machine is controlled to stop immediately, or, if wrapping is in progress, to be stopped after the wrapping is completed. The packaging control unit 23 also receives the signal T and counts it. In batch processing mode, which will be described later, the wrapping operation is stopped as soon as the count reaches a predetermined value.

The packaging box detection switch 28 detects that the normally wrapped coin storage section 15 is inserted at a predetermined position, and provides a detection signal to the packaging control section 23 .

FIG. 2 shows a control section of the coin wrapping machine of FIG. 1.

The packaging control unit 23 includes a memory 102 (ROM,
A central processing unit (CPU) 10 that operates based on programs and data stored in RAM (consisting of RAM)
1. As shown in FIG. 3, the memory 102 is provided with a memory area 601 for counting the number of stacked sheets, a memory area 602 for counting the number of wrapped sheets, a memory area 603 for setting the number of wrapped sheets, and a memory area 604 for setting the number of wrapped sheets.

The packaging control unit 23 further includes a counting control unit 114 that controls the rotational drive of the turntable 2, and a packaging control unit that controls packaging operations such as driving the wrapping paper supply motor, packaging roller drive motor, and coin guide drive motor. 113. The packaging control unit 23 also includes a bus BUS, and each detection unit 1,
It receives signals from 20, 24, and 28, provides drive signals to each drive section 6, 14, and 26, and also exchanges signals with operation instruction input section 27.

The denomination setting section 105 of the operation instruction input section 27 sets the denomination of the packaged coin, and includes, for example, a denomination setting knob.

The numeric keypad 106 is used to input the desired number of wrapped coins, etc.

Start switch 107 is operated to instruct the start of the wrapping operation.

The clear switch 108 is operated in combination with other keys and is used to clear the corresponding data.

The data display section 109 includes a coin number display section 606 and a packaging number display section 607 as shown in FIG.
and a set number display section 608, which are respectively a stacked number counting memory area 601 and a set number display section 608, which will be described later.
The contents of the packaging number counting memory area 602 and the packaging number setting memory area 604 are displayed numerically.

The data display section 109 further includes a packaging number setting display lamp 609 and a packaging number setting display lamp 61.
0, and these light up when the number of packages and the number of packages are set, respectively. The data display section 109 further includes a packaging batch completion lamp 611 that lights up when packaging of the packaging batch is completed.

The packaging batch mode designation switch 111 is used when packaging is performed in batch mode, that is, when the numeric keypad 10
6, and is operated when wrapping the number of bottles stored in the memory area 604. If the batch mode designation switch 111 is not operated, wrapping will continue as long as the supply of coins continues.

The number of wrapped coins input designating section 112 is operated when the number of wrapped coins in one package is desired to be changed. This input designation section 112 may be configured with a switch provided for each denomination, for example, or may be a switch common to all denominations and operated in combination with the denomination setting section 105.

5 and 6 respectively show the counting operation and packaging control operation of the control section shown in FIG. 2. The control unit can perform these operations in parallel.

First, the counting operation will be explained with reference to FIG.

When the packaging batch mode designation switch 111 is turned on (501), the numeric keypad 106 for the number of items to be packed is pressed.
can be set or changed by

When the numeric keypad 106 is operated (502), the set number is written into the packing number setting memory area 604 (503).

If you want to correct the numerical value entered using the numeric keypad 106, turn on the clear switch 108 (504).
The contents of the packaging number setting memory area 604 are cleared (505) and the process returns to step 501.

If not cleared, turn on the start switch 107 (504A) and proceed to step 506A, which will be described later.

In step 501, set the packaging batch mode switch 1.
11 is off, the start switch 107 is not operated (506), and the clear switch 108 is
If not operated (507), the process returns to step 501.
When clear switch 507 is operated, memory 1
It is determined whether or not the coin number counting memory 601 of No. 02 is zero (508), and if it is not zero, the coins in the cylinder are removed (509) and the process returns to step 501.

When the start switch 107 is operated in step 506, the shutter is closed (506A) and counting drive is started (510). That is, by rotating the rotary disk 2 by the counting drive unit 114,
The coins are sequentially led out to the passage and conveyed by a conveyor belt (not shown). Then, each time a coin is detected by the coin detection unit 1 (511), the RAM 1
03 is incremented by 1 to the contents of the coin number counting memory area 601.

Packaging number setting memory area 60 of memory 102
When the contents of the stacked coin number counting memory area 601, that is, the number of coins to be counted match the contents of 3, that is, the set number (for example, 50), the counting drive is stopped (514). That is, the counting drive unit 114 is stopped, the stop solenoid 26 is energized, the stop lever 3 is projected into the passage, and the conveyance of subsequent coins (from the 51st coin onwards) is stopped, and the excess coins are removed from the cylinder. 4. Prevent them from entering. Then, after waiting for the shutter to open (514A), the stacked sheet number memory area 601 is cleared (514B). Then, it is determined whether the contents of the packaging number counting memory area 602 match the set value (514C), and if they match, the process ends. If they do not match, the process returns to step 506A.

If the number of stacked sheets does not match in step 513,
It is determined whether or not the presence of coins in the rotating disk 2 is detected within a predetermined time, that is, whether or not the supply of coins continues (534), and if so, the step
Return to 511. If not, the counting drive section 11
4 is stopped (535). Then, if it is not the packaging batch mode (536), the process ends. If it is the packaging batch mode, it is determined whether the contents of the packaging number counting memory area 602 match the set value (537), and if they match, the process ends. If they do not match, the packaged number display section 607 is blinked (538) to indicate that the desired number of packaged coins has not been obtained. In this case, if you operate the start switch 107 after additionally supplying coins (539), the blinking will stop and the process will return to step 506A.
Counting continues. If the start switch 107 is not turned on (539) and the clear switch 108 is turned on (540), the process returns to step 508 and counting is stopped even if the number of wrapped coins is less than the desired number.

Next, the packaging control operation will be explained with reference to FIG.

If the number of stacked sheets matches (515), then the presence or absence of stacking abnormality is checked (515A). That is, it is checked whether or not the cylinder stand signal B is input to the abnormality detection section 20. If it has been input, an abnormality signal G1 is output and elimination processing is performed (541). That is, the coins are discharged into the storage section 16. At this time, switching lever 1
3 is not activated (held in the position shown).

If the stand signal B is not input, it is then determined whether packaging is possible (516). That is, it is determined whether or not the coin guide 9 is located below the shutter 5 by a detection means (not shown). If it is located on the lower side, that is, if packaging is possible, the shutter drive solenoid 6 is energized by giving a release signal F;
Open shutter 5 and then close it (517).

When a detection switch (not shown) confirms that the shutter 5 is closed (518), the packaging drive unit 113 starts the packaging operation (519).

If the wrapping paper shortage signal C and the number shortage signal D are input to the abnormality detection unit 20 before the wrapping operation ends,
An abnormality signal G2 is output, and abnormal coin removal processing is performed (541). When there is no packaging abnormality, that is, when packaging is completed normally, the chute switching drive section 14 is activated by the switching signal I, and the switching lever 13 is switched (521), thereby guiding normally wrapped coins to the discharge port 12. When the shoot changeover switch detects the changeover operation of the shoot (522), +1 is added to the packaging number counting memory area 602 (523).

Next, when not in packaging batch mode (524),
Return to step 515. When in the packaging batch mode (524), the contents of the packaging number setting memory area 604,
That is, the memory area 602 for counting the set number of pieces and the number of packages packed.
, ie, the counted number, and if they do not match, the process returns to step 513. If they match, the packaging drive unit 113 is stopped (526). Then, the packaging batch completion lamp 611 of the data display section 109 is turned on for a predetermined period of time (527). If the contents of the coin number counting memory area 601 are zero, it is assumed that there are no coins in the stacking tube 5, and the packaging number counting memory area 604 is cleared (531), and the process ends.

If it is not zero in step 528, then it is determined whether the start switch 107 has been operated for restarting (529). That is, after the completion of step 527 is displayed, it is determined whether the start switch 107 has been turned on. If it is turned on, the packaging number counting memory area 602 is cleared and the process returns to step 515.

If not turned on at step 529, the steps continue until clear switch 108 is turned on (532).
Repeat 529 and 532. When the clear switch 108 is turned on, the stacked coin count memory area is cleared (532A), and the coins in the cylinder 5 are removed by temporarily opening the shutter (532B), and the process ends.

Note that the CPU 101 corresponds to a chute switching drive control means, a coincidence determination means, and a packaging operation stop means in the claims.

In the above embodiment, the display section 607 is made to blink in order to indicate that the desired number of packages has not been wrapped in step 538, but a lamp is provided separately from the display section 607. It is also possible to turn on the .

In addition, in step 529, it is determined whether the start switch is turned on for restarting, but instead, it is detected that the normal coin collecting section 15 has been pulled out and reinserted, Alternatively, the process may be restarted (proceeding to step 530).

〔Effect of the invention〕

As described above, according to the present invention, since normal coins are counted based on the switching detection signal of the chute switching member, which is normally at the abnormal coin ejection position, to the normal coin ejection position, a sensor is provided on the passage. Reliable counting is possible without any problems.
