Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized in that stacked coins are rotated by a plurality of wrapping rollers, at least one of which is a movable wrapping loaf, and the wrapping paper fed by a paper feed roller is wrapped around the stacked coins. This invention relates to an improvement of a coin wrapping machine that wraps the coin around its surroundings.

In such a coin wrapping machine, when there are no coins between the wrapping loaves, or when some coins are piled up between the wrapping rollers but some of them have collapsed for some reason, the coins are stacked together. If an abnormal condition occurs, the coins will not be wrapped normally.

Conventionally, there was no suitable method for detecting such an abnormal condition of the loaded coins between the wrapping rollers, so even if an abnormal condition of the loaded coins occurred, the packaging process was carried out in a normal condition.

In addition, the wrapping paper is fed between the wrapping rollers even though there are no coins in the vehicle between the wrapping rollers, and the wrapping paper is rolled up by the winding needle. As a result, the wrapping paper section cannot be reused and must be removed. In addition, even if coins are misaligned between the wrapping rollers, the winding operation by the winding needle, the movement of the paper guide near the wrapping rollers, and the movement of the loading coin support mechanism located at the wrapping position will be necessary. The movable packaging roller moves back and forth with respect to the stacked coins, and as a result, the coins that have fallen off the coins get caught in these mechanisms, causing damage to the mechanisms. The present invention has been made in view of the above points, and includes an arm that supports a movable packaging roller and is rotated at a predetermined time of the packaging process to move the movable packaging roller in a car model coin clamping direction; is rotated and moved to a position corresponding to a position corresponding to a position of the movable packaging roller,
comprising a first detection means for detecting that the arm has moved to a pinching compatible position, and a second detecting means for detecting that the arm has moved excessively beyond the pinching compatible position,
It is an object of the present invention to provide a coin wrapping machine that makes it possible to detect an abnormal state of coins loaded in a car between wrapping rollers by detecting the movement status of an arm of a movable wrapping roller.

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

FIGS. 1, 2, and 4 show a so-called tubeless type embodiment in which coins are fed from a rotating disk to between wrapping rollers without passing through a coin alignment tube.

Of these, FIG. 1 schematically shows the entire system, and a rotating disk 3 is provided which is rotationally driven by a motor 1 and transfers coins (not shown) one by one to a coin passage 2.

A scraping belt (driven by a motor, not shown) faces above the coin passage 2 and forcibly transfers the coins in the passage 2. A star wheel 4 faces inside this passage 2, and It is designed to count the coins transferred inside. A gear 5 is coaxially disposed on the star wheel 4, and a large gear 6 meshes with the gear 5. Therefore, a hole 7 is bored in this large gear 6,
When the predetermined number of sheets has been counted, a stopper 8 is engaged with the hole 7 to prevent the large gear 6 from rotating any further.
As a result, the rotation of the star wheel 4 is also restricted,
Transfer of coins exceeding a predetermined number is stopped. On the other hand, when the stopper 8 is engaged with the hole 7 of the large gear 6, a switch 9 facing near the stopper 8 is operated, and the motor 1 is stopped. A guide (not shown) is provided on the downstream side of the coin passage 2, and coins are passed through this guide 3 to packaging rollers 10, 11,
The vehicle is designed to be overturned onto a lower support plate 13 between 12 and 12.

The packaging rollers 10, 11, 12 are rotated by a belt 17 wound around a pulley 16 attached to an output shaft 15 of a motor 14 which is continuously driven after the start button is pressed. It has become. A clutch mechanism 18 is slidably and rotatably disposed on the output shaft 15. This clutch mechanism 18 is moved by energizing and deenergizing a solenoid 19, and the output shaft 15 is moved by the energization and deenergization of a solenoid 19. It is possible to take a position where the rotation is transmitted to the gear 20 and a position where the rotation is not transmitted by deenergizing the solenoid 19. The gear 20 is connected to a gear 23 fixed to a camshaft 22 via a speed change gear 21, and the packaging rollers 10, 11, 12 are connected to the camshaft 22 according to the diameter of the coins to be wrapped. A cam 24 that moves from the waiting position to a clamping position where it presses against the circumferential surface of stacked coins, a cam (not shown) that controls the movement of the lower support plate 13, and a cam shaft 2.
A cam 25 and the like is attached to detect the localization calendar of No. 2 and to detect the presence or absence of wrapping paper. The cam 25 has 90
A pair of notches 26 and 27 are formed at an angle o, and this notch 26 corresponds to the localization layer (third illustrated position) of the camshaft 22, and the actuator of the switch 28 is located in the notch 26.
When the user falls down, the solenoid 19 is deenergized to stop the camshaft 22 in the positioning layer, and a solenoid 42, which will be described later, is energized to stop the paper feed drive roller 32 from rotating. Further, when the actuator of the switch 28 is calibrated to the notch 27, the switch 28 is turned off, and if a switch 37, which will be described later, is turned off at that time, the solenoid 19 is turned off.
The rotation of the output shaft 15 of the motor 14 is controlled by the camshaft 22.
It is designed not to be transmitted to The details of the functions of the cam 25 and switch 28 will be described later. A wrapping paper supply device 30 is disposed on the side of the wrapping roller 10 to supply wrapping paper 29 that is passed around the circumference of the coins stacked on the lower support plate 13.

This wrapping paper supply device 30 includes a driving roller 32 and a driven roller 3 that feed wrapping paper 29 from a wrapping paper roll 113.
3, a curved guide plate 34 that guides the wrapping paper 29 to the wrapping roller 10, a cutter 35 that cuts the wrapping paper 29 under tension, and a wrapping paper detection piece that detects the tension state of the wrapping paper 29. 36, the wrapping paper detection piece 36 is activated by rotation due to the pressure of the tensioned wrapping paper 29, and the solenoid 19 is kept in an excited state to rotate the output shaft 15 of the motor 14 to the camshaft 22.
It has a switch 37 that allows the transmission to continue. Note that the solenoid 19 is initially connected to the switch 9.
After that, the switch 28 is connected to the parallel circuit of the switch 37, so that the cam is activated when both switches 28 and 37 are in the OFF state or when the camshaft 22 returns to the stereotaxic layer. 25 notches 2
It is only deenergized when switch 28 is toggled at step 6. The paper feed drive roller 32 is coaxially equipped with a friction roller.
A roller 38 is attached, and a friction roller 40 coaxial with a pulley 39 rotated by the belt 17 running by the rotation of the output shaft 15 of the motor 14 faces near the wear roller 38.

Therefore, a clutch friction loaf 41 is provided which can take a position where it contacts both of the friction rollers 38, 401 and a position where it is separated from both of these rollers 38, 40. This is achieved by rotating the solenoid 42 by energizing and deenergizing it. The biasing of the solenoid 42 (cutting off of rotation transmission of the drive roller 32) is accomplished by pressing a switch 43, which will be described later, with a pin 81. Further, in a normal packaging process, the actuator of the switch 28 falls into the notch 26 of the cam 25 and the switch 28 is switched to energize the solenoid 42. FIG. 2 shows the details of the vicinity of the wrapping rollers 10, 11, 12 of the coin wrapping machine of FIG. It is structured so that it can be separated freely.

FIG. 4 is an extracted diagram of the wrapping rollers 10, 11, 12 and their link mechanism.
5 is attached to the cam 45, and an arm 481 which is fixed to a rattan 47 supported on a base 46 and rotates around its shaft 47; a roller 50 of an arm 49 whose one end is pivotally attached is attached to the cam 45; I am supported.

3 The end of the link 51 supports the upper and lower ends of the packaging roller 12, and the base is connected to the shaft 5.
The packaging roller support arm 54 is connected to the packaging roller support arm 54 which is swing-backed at 3. A link 55 is connected to one end of the packaging roller support arm 54, and this link 55 is further connected to a packaging roller support arm 57 which supports the upper and lower ends of the packaging roller 0 and is mounted on a shaft 56.

A packaging control cam 24 is attached to the camshaft 22 for determining the operation timing of each part of the coin packaging machine including the packaging device, and this cam 24 controls the movement of the packaging rollers 10, 11, 12 in the packaging process. The fourth illustrated position becomes the localization calendar.

Further, an arm 59 having a roller 58 that abuts the cam 24 is suspended on the shaft 47, and a tension spring 6 is connected between the arm 59 and the packaging roller support arm 54.
0 is tensioned, and a stopper screw 59a fixed to the arm 59 is fitted onto the arm 52 (see FIG. 4).
In addition, in FIG. 2, the roller 58 is mounted on the large cam surface 24b of the cam 24, so the stopper screw 59a
is separated from the arm 52, and a supported state between the roller 58 and the large cam surface 24b is ensured.
In FIG. 2, the three packaging loaves 10, 11, 1
2, the packaged coin C is placed in the coin receiving space formed by
and a main guide member 61 for guiding the wrapping paper 29
, 62, 63 and sub-guide members 64, 65, 66 are provided. That is, the first main guide member 61 is connected to the shaft 67.
One end thereof is connected to the packaging roller support arm 52 by a link 68. The second main guide portion 62 is loosely attached to a shaft 69, and one end thereof is attached to a link member 70.
It is connected to the packaging roller support arm 54 through its legs. The third main guide member 63 has one end connected to the packaging roller support arm 54 via a link member 71, and an arm 74 having a roller 73 that runs against a cam 72 provided on the cam shaft 22. is loosely connected to the shaft 47,
One end of the arm 74 is connected to the third main guide member 63.

The tips of the main guide members 61, 62, and 63 are cut obliquely on the back side and are formed sharply, and the tip of the first main guide member 61 faces the coin receiving space of the packaging loaf 11. A second main guide member 62
The tip of the packaging loaf 12 and the third main guide member 6
The tips of 3 extend adjacent to each of the packaging rollers 10. On the other hand, the second and third sub-guide sections 65, 66 of the sub-guide members 64, 65, 66 are the second and third sub-guide sections.
An arm 76 is fixed to the packaging roller support arms 54 and 57, the first sub-guide member 64 is loosely attached to the shaft of the packaging roller 11, and one end of the arm 76 is loosely attached to the shaft 47 via a link 75.
This arm 76 is connected to a link member 77 that is connected to two ends of the third main guide member 63. Next, a switch 78 is attached to the arm 48, and this switch 78 is connected to the actuator 7.
9 is pressed by arm 49, it is turned off.

In addition, the roller 50 and the denomination cam surface of the denomination cam 45 are kept in a constant position even when the arm 48 rotates about the shaft 47 (however, when changing the denomination, the roller 50 supports the denomination cam surface of the denomination cam 45). Since the denomination cam surface to be used is changed, this constant position becomes a different constant position as the denomination changes.

) to position this arm 49 at
A coil 80 is provided that biases the actuator 79 in a direction opposite to the pressing direction of the actuator 79. On the other hand, when the packaging process is inactive, that is, when the camshaft 22 and the cam 24 are
4), the stopper 48a of the arm 48 comes into contact with the arm 49, and the position of the arm 48 is determined.The arm 48 is fixed to the shaft 47 together with the arm 48, so that it is integrated with the arm 48. The position of the arm 52 is also determined. The position of the arm 59 is also determined by the stopper screw 59a coming into contact with this arm 52. In order to ensure that the stopper screw 59a of the arm 59 supports the arm 52, the small diameter cam surface 24a of the packaging control cam 24 is shaped to be spaced apart from the roller 58 positioned opposite to it. Although the distance between them varies depending on the change in denomination due to the rotation of the denomination cam 45, even when the roller 530 contacts the largest coin flea cam surface of the denomination cam 45, the small diameter cam surface of the packaging control cam 24 A gap is formed between 24a and roller 58. Therefore, when the camshaft 22 and the camshaft 24 are in the positioning layer (the position in FIG. 4), the roller 583 is not restrained by the small diameter cam surface 24a, and therefore the arm 59 on which the roller 58 is installed is t
The tension spring 601 biases the arm 54 counterclockwise around the shaft 47 and holds it in a position determined by the engagement of the stop collar screw 59a and the arm 52, and the arm 542 and the arm 48 are fixed to the shaft 47 and integrated. Therefore, the tension spring 60
The stopper 48a is held in a position where it rests against the arm 49 due to the urging force of the stopper 48a.

At this time, the packaging roller 11 attached to the tip of the arm 52 is positioned at a moving position corresponding to the denomination coin diameter determined by the denomination cam surface of the denomination cam 45, and the packaging roller 12 is attached to the link 51 and the arm 57. Each movement is located at a standby position via. Further, when the denomination is changed due to the rotation of the denomination cam 45 and the roller 50 comes into contact with another denomination cam surface, the arm 49,
An arm 48 in which a stopper 48a abuts on this arm 49
, arm 52, link 51, arm 54, link 55,
Each packaging roller 10, 11, 12 is adjusted and positioned through the arm 57 to a movement waiting position corresponding to the denomination coin diameter. As described above, when the cam koji 22 is in the orientation layer shown in FIG. It is becoming. The cam ball 22 makes one rotation in the direction of the arrow from the positioning layer (FIG. 4), and the packaging process is carried out by one rotation, but at a predetermined time in the packaging process, that is, at a predetermined time during one rotation of the camshaft, the roller 58 rotates. I'll ride it.

As a result of this lifting, the arm 59 swings about the shaft 47 and is positioned at a position determined by the large cam surface 24b. This swinging causes the stopper screw 59a to
The arm 52 and the arm 48 also swing clockwise about the shaft 47 integrally with the arm 59 in order to maintain the supporting state with the arm 52. If there are no loaded coins between the wrapping rollers 10, 11, and 12, the arms 52, 48, and 59 integrally follow the movement of the roller 58 from the small-diameter cam surface 24a to the large-diameter cam surface 24b. will be moved. However, if a normal stacked coin exists between the wrapping rollers 10, 11, and 12, the movement of the arms 52 and 48 is blocked by the circumferential surface of the stacked coin and temporarily stops, and only the arm 59 has a large diameter. Climb onto the cam surface 24b. When the arm 52 is temporarily stopped, the arm 54 and the wrapping rollers 12 and 10 are also temporarily stopped at the stacked coin pinching position. In order for the switch 48 to detect that the wrapping roller 11 has moved to a regular stacked coin clamping position that varies depending on the denomination coin diameter, the wrapping roller 1 was moved to a position immediately before the stacked coin placement position. Arm 49 is adapted to turn on the actuator of switch 78. Therefore packaging roller 1
When 0, 11, and 12 come into contact with the circumferential surface of a normal child coin C, the arm 48 rotates clockwise enough, so the arm 49 separates from the actuator 79, and when the coin collapses, the arm 48 If the actuator 49 cannot be rotated clockwise enough, the actuator 49 will not separate sufficiently from the actuator 79 and will continue to be in contact with the actuator 79.
8 is maintained in the off state. Furthermore, the detection signal of the on/off state of the switch 78 is wrapped in the wrapping paper 29. The timing is used immediately before the coin is inserted between the rollers 10, 11, and 12 (immediately after the coin is pinched by the wrapping rollers 10, 11, and 12), and the timing is switched at that time, for example, by the timing cam of the cam shaft 22. Based on both the timing signal of a switch (not shown) and the detection signal of the switch 78, the drive of the motor 14 is stopped when the switch 78 is in the OFF state at the time. Further, a pin 81 that protrudes toward the spring 60 is provided at the end of the arm 54 on the spring 60 side.
This pin 81 is provided so as to protrude from the base 46, and this pin 81 is connected to the actuator 8 of the switch 43, which is attached to the bracket 82 that is protruded from the base 46.
3 and is separated by an interval.

Therefore, the carload of coins C is placed between the wrapping rollers 10, 11, and 12.
If not, each packaging roller 10, 11, 12 rotates over a predetermined stroke, but at this time, the pin 81 presses the actuator 83 of the switch 43 to turn on the switch 43, and the clutch friction roller 41 described above The paper feed drive roller 3 was rotated without being transmitted to the friction roller 38 by energizing the solenoid 42 of the friction roller 40.
2 stops rotating, and the paper feeding operation of the wrapping paper 29 is stopped.
When the switch 43 is switched to the normal position by the pin 81, that is, when the paper feeding operation by the paper feeding drive roller 32 and the driven roller 33 is stopped, the tip of the wrapping paper 29 is between the wrapping rollers 10, 11, 12. (immediately after the stacked coins are attached by the wrapping rollers 10, 11, 12), when the switch 43 is turned on, the tip of the wrapping paper 29 is inserted into the wrapping loaf 10, It is not inserted between 11 and 12.

Taking advantage of the fact that the leading end of the wrapping paper 29 is not inserted between the wrapping rollers 10, 11, and 12, the switch 37 that is scheduled to be switched immediately after the wrapping paper 29 is cut is not switched and remains in the off state. , so that switch 2
8 is turned off (by the notch 27 of the cam 25), the solenoid 19 is de-energized, and the camshaft 22 is stopped at a position halfway through the packaging process. The stopping position of this camshaft 22 is the pin 81.
This position corresponds to the time immediately after the switch 43 is turned on. Because packaging rollers 10 and 11
, 12 is faster than the rotational speed of the paper feed rollers 32, 33, and the tip of the wrapping paper 29 is sent between the wrapping rollers 10, 11, 12 which are rotating to pinch the coins, and the wrapping paper 29 is wrapped. This is because the paper is wrapped around the circumferential surface of the stacked coins and is tensioned, and the tension is used to turn on the switch 37. In this way, unlike the case of the switch 78, in this embodiment, a method for directly stopping the motor 14 by turning on the switch 43 or directly de-energizing the solenoid 19 to stop the camshaft 22 is not explored. When the switch 43 is turned on, the camshaft 22 is indirectly stopped through the switch 37 which detects the tensioning action of the wrapping paper 29. The reason for this is that the period from when the switch 43 is turned on to when the switch 37 detects the tension in the wrapping paper 29 is very short, so the switch 37 can be used, and the circuit and structure can be simplified. This is due to the fact that we are trying to achieve this. Note that the reference numeral 84 in FIGS. 2 and 4 indicates the arm 5.
4 is a stopper for preventing the switch 43 from approaching the switch 43 by a predetermined distance or more. Therefore, the stopper 84 is positioned in such a position that the minimum denomination cam surface of the denomination cam 45 does not interfere with the adjustment of the denomination of the arms 49 and 48.

As explained above, according to this embodiment, all three are movable packaging rollers, and the packaging roller support arms 52, 54, 57
The arms of the present invention are designated as packaging roller support arms 52 or 54 because they move in a corresponding manner in conjunction with each other.
The first detection means of the present invention includes the arm 48 and the topper 48a.
, arm 49 , roller 50 , switch 78 , actuator 79 , coil spring 80 , and second sensing means are shown as switch 43 , pin 81 on packaging roller support arm 54 , tension spring 60 .

In this embodiment, considering the packaging of denomination coins with large diameter differences, the moving position of the movable packaging roller can be adjusted according to the denomination coin diameter, and the adjustment mechanism is It is shared with the mechanical parts of the first detection means (arm 49, roller 50, arm 48, stopper 48a, coil spring 80), and a part of the moving mechanism of the packaging roller 12 (part of the packaging roller support arm 54). It is shared with the mechanical part of the second detection means. Next, the operation of the above-described embodiment will be explained.

With the cam shaft 22 and the packaging control cam 24 in the orientation layer (the fourth position shown), turn the denomination setting knob to set the denomination cam 45.
The corresponding denomination cam surface is brought into contact with the loaf 50. As a result, the arms 49, 48, packaging roller support arm 52, and arm 59 are integrally swung around the ball 47 through the roller 50, and are positioned at positions corresponding to the denominations. Therefore,
The packaging roller 11 supported at the tip of the packaging roller support arm 52 is positioned at a waiting position corresponding to the denomination coin diameter. Also, through the link 51 the packaging loaf support arm 54
The packaging roller 2 is also positioned at a moving position corresponding to the denomination coin diameter, and the link 55
The packaging loaf support arm 57 is also swung about the shaft 56 via the packaging roller 0, and the packaging roller 0 is positioned at a waiting position corresponding to the denomination coin diameter. By matching this denomination, switch 78
is moved to a position corresponding to the denomination while being kept pressed by the arm 49. First, to explain the normal operation, when a start switch (not shown) is pressed, the counting motor 1 and the packaging motor 14 are driven, and the rotating disk 3 is rotated and the scraping belt (not shown) is driven. runs, and on the other hand, the packaging rollers 0, 11, 12 rotate via the output shaft 15 of the motor 4, the pulley 16, and the belt 17.

Coins are sequentially transferred on the coin path 2 by the rotation of the rotary disk 3 and the running of the scraping belt, and the transfer of the coins causes the star wheel 4 to rotate and the number of coins to be counted. The counted coins are sequentially dropped into a space surrounded by packaging rollers 10, 11, and 12, and are received on a support plate 13 located at the bottom of this space and placed in a horizontal position, with subsequent coins also sequentially placed in a horizontal position. The vehicle is loaded.

When a predetermined number of coins are counted in this way, the large gear 6
The stopper 8 is engaged with the hole 7, the switch 9 is turned on, the solenoid 19 is energized, the clutch mechanism 18 and the gear 20 are engaged, and the camshaft 22 is moved from the orientation layer in FIG. 4 via the gear 23. One rotation is started in the direction of the arrow, and the first packaging process (camshaft 22
one revolution) is started. At the same time that the camshaft 22 starts rotating, the actuator of the switch 28 that has been placed in the notch 26 of the cam 25 is pushed up and the switch 28 is switched, deenergizing the energized solenoid 42 and deenergizing the belt 17. The sheet feeding drive roller 32 is rotated through the clutch frictionless roller 41 and the friction roller 38, and the sheet feeding operation of the wrapping paper 29 is started. Next, a cam (not shown) of the camshaft 22 causes the lower support plate 113 to lift up the child stack coin by the amount of swaging margin (about 10 mm) of the wrapping paper and support it in the wrapping position.

The roller 58 directly contacts the small diameter cam surface 24a of the cam 24 just before the large cam surface 24b, and as the cam 24 rotates, the roller 58 rides up on the large cam surface 24b, and the arm 5
9 swings around the shaft 47 to a position determined by the light and large force cam surface 24b and temporarily stops, and is held at that position until the loaf 58 falls onto the small diameter cam surface 24a. On the other hand, arm 52
The arm 48 attempts to swing integrally with the arm 59 via the tension spring 60, but in the middle of the swing, the wrapping loaf 11 hits the circumferential surface of the car load of coins C and is temporarily stopped.
This position is the ball landing position of the packaging roller 1, and the arm 5
2 and the arm 48 are also temporarily stopped at a nipping position corresponding to the approaching position of the packaging roller 11. The arm 59 swings further until the roller 58 swings to the position where it supports the large-diameter cam surface 24b and is temporarily stopped, so that when the wrapping roller 11 comes into contact with the circumferential surface of stacked coins, the stopper of the arm 59 The screw 59a will be separated from the arm 52. The packaging roller support arm 52 is moved to the position corresponding to the heavy coin circumference by moving the packaging roller 12 through the link 51 and the second packaging roller support arm 54, and by moving the packaging roller 10 through the link 55 and the third packaging roller support arm 57. The stacked coins are temporarily stopped at the clamping position where they contact the surface and rotated. The movement of the arms 52, 54, and 57 to the pinching position positions the sub-guide member 64 through the sub-guide members 65, 66, the arm 76, and the link 75 to a position corresponding to the denomination coin diameter. Furthermore, the main guide member 61 is connected through the link 68, and the link member 70 is connected to the main guide member 61 through the link 68.
through the main guide member 62, and the arm 7 whose position is determined by the roller 73 located on the small diameter cam surface of the cam 772.
4 and the main guide member 63 is positioned via the link member 71 at a position corresponding to the denomination coin diameter. Through the above operations, the wrapping roller 12 and the wrapping rollers 10, 11 come into contact with the circumferential surface of the coin C of the vehicle type on the lower support plate 13, and the first, second, and third main guide members 61, 62, 63
and the sub-guide members 64, 65, 66 are positioned Z close to the circumferential surface of the coin C. In this way, the wrapping rollers 10, 11, 12 come into contact with the circumferential surface of the normal child stack coin C, so the arm 48 is positioned at the corresponding position, and the pressing state of the switch 78 by the arm 49 is released, and the loaf 1
2 is restricted from moving on the circumference of a normal vehicle load coin C, the pin 81 of the arm 54 does not act on the actuator 83 of the switch 43, and therefore the solenoid 42 remains deenergized. , the paper feeding drive roller 32 continues to be rotated via the friction rollers 40, 41, and 38, and the wrapping paper 29 is further fed by this roller 32 and the driven roller 33, and immediately after the switch 78 is turned on. The wrapping paper 29 enters between the wrapping rollers 10, 11, 12 and the circumferential surface of the piled coin C, and the wrapping paper 29 is wound around the circumferential surface of the coin C by the rotation of the wrapping rollers 10, 11, 12. Ru. Immediately after that, the roller 73 rides up on the large cam surface of the cam 72, and the main guide member 63 is retracted outward through the arm 74, and the winding needle (not shown) is moved by the cam (not shown) of the cam shaft 22. The coins are inserted into the vehicle and moved toward each other in the axial direction, and the crimping operation of the crimping margins at the upper and lower ends of the wrapping paper 29 that protrudes upwardly and downwardly from the vehicle's coins is started. Meanwhile, the wrapping paper 29 continues to be wrapped around the circumferential surface of the stacked coins.
Therefore, since the rotation of the wrapping rollers 10, 11, 12 is farther than the rotation of the paper feed rollers 32, 33, the wrapping paper 29
is tensioned and cut into a predetermined length by a cutter 35. Immediately before cutting the wrapping paper 29, the notch 2 of the cam 25 is cut.
The actuator (not shown) of the switch 28 of No. 7 should engage and de-energize the solenoid 19.
At this time, the detection piece 36 rotates due to the tension of the wrapping paper 29 and turns on the switch 37, so the solenoid 19 continues to be energized, and the rotation of the output shaft 15 of the motor 14 is caused by the camshaft 2.
2, and the predetermined wrapping operation is interrupted. Then, the winding of the wrapping paper 29 of a predetermined length around the circumferential surface of the child's coin C and the crimping of the vertical margins of the wrapping paper 29 at both ends are completed, and the crimping with the winding needle (not shown) is completed. The winding needle is moved vertically and horizontally by a cam 22 (not shown), and then the lower support plate 13 is also moved downward and horizontally, and then the packaging roller 1
0, 11, 12, the main guides 61, 62, and the sub-guide members 64, 65, 66 also retreat and return to their waiting positions, and the wrapped military coins are discharged downward.

Immediately after that, the support plate 13 returns and the packaging rollers 10, 1
It stops at the initial position covering the lower part of numbers 1 and 12. On the other hand, since the solenoid 42 is in the de-energized state, the leading end of the cut succeeding wrapping paper 29 is moved from the cutter 35 along the guide plate 34, and is transferred to the notch 26 of the cam 25 by the switch 2.
When actuator 8 is depressed, that is, camshaft 2
2 returns to the localization layer (the position in FIG. 4), the switch 28 is switched, the solenoid 42 is energized, and the feeding of the following wrapping paper 29 is stopped. Thereafter, the leading end of the wrapping paper 29 is then stopped at an intermediate position between the cutter 35 and the wrapping roller 10. On the other hand, the above-mentioned switching of the switch 28 deenergizes the solenoid 19, stops the camshaft 22 in the normal position shown in FIG. 4, and raises the stopper 8 by means of a solenoid (not shown). As a result, the motor 1 is rotated, the rotating disk 3 and the scraping belt (not shown) are driven, and the counting and stacking operation is restarted. Next, packaging roller 1
A case where an abnormal state of 0 military coins occurs between 0, 11, and 12 will be explained.

An abnormal condition of stacked coins is coin collapse (for example, coins that have fallen from the coin passage 2 are not properly stacked on the support plate 13, or coins are collapsed when moving coins that have not been stacked to the packaging position, etc.) In the evening, the diameter of the stacked coins is larger than the regular diameter, so the wrapping rollers 10, 11, 12 cannot move to the regular stacked coin clamping position, and the arms 52, 54, 57 also cannot move to the attachment corresponding position. Therefore, the actuator of the switch 78 does not fully separate from the arm 49 and remains pressed, and the switch 78 remains in the OFF state, and the timing cam of the camshaft 22 causes the timing switch (not shown)
(the tip of the wrapping paper 29 is the wrapping roller 10,
11 and 12), the packaging motor 4 is stopped by a detection signal of the off state of the switch 78, and the packaging rollers 10, 11, 12, cam shaft 22, paper feed drive roller 32, and driven roller 33 are rotation is stopped and the packaging process is interrupted. Next, if the abnormal state of military stacked coins is the absence of stacked coins (a predetermined number of coins are counted by the star wheel 4 in the coin passage, The stacked coins are not present due to the fact that the counted coins get stuck in the guide mechanism provided between the packaging rollers 10, 11, and 12, and are not fed into the space between the packaging rollers 10, 11, and 12. In the case of a coin standing at the entrance of the packaging roller space due to a coin jamming in the guide mechanism (due to the occurrence of a coin stuck in the jammed coin in the guide mechanism and suspended at the entrance of the packaging roller space) I will talk about things like

In the case of such an abnormality of stacked coins, the wrapping rollers 10, 1
1 and 12 move excessively from the normal stacked coin pinching position, and the packaging roller support arms 52, 54, 57 corresponding to each packaging roller 10, 11, 12 also move from the pinching position. Move further. As a result, pin 8 of arm 54
1 presses the actuator 83 of the switch 43, the switch 43 is switched, the solenoid 42 is energized, the clutch friction roller 41 is separated from the friction rollers 38 and 40, and the rotation of the paper feed drive roller 32 and the driven roller 33 is stopped. The paper feeding drive operation is stopped. (At this time, the tip of the wrapping paper 29 is at the position just before being inserted into the wrapping rollers 0, 11, and 12.) Immediately after that, the actuator of the switch 28 falls into the notch 27 of the cam 25 of the rotating camshaft 22, and the switch 28 is turned off, while the switch 37 remains off since the wrapping paper 29 is not tensioned at that time. Therefore, the solenoid 19 is deenergized and the camshaft 22
is also stopped, stopping the packaging process from proceeding. If an abnormal state of stacked coins occurs as described above, and the supply of wrapping paper and the progress of the wrapping process by stopping the camshaft are stopped, press the stop button (not shown) and press the stop button (not shown) to remove the coins between the wrapping rollers. Alternatively, remove the coins in the guide mechanism, rewind the wrapping paper 29, and place the tip of the wrapping paper 29 at an intermediate position between the wrapping roller 10 and the cutter 35 (the position where the tip of the wrapping paper 29 is retracted when the camshaft 22 is in the positioning layer). Clear button after positioning (not shown)
When the clear button is pressed, the packaging motor 14 is driven, the solenoid 19 is energized, and the camshaft 22 is restarted from the stopped position.

In the case of stopping the camshaft 22 based on the switch 78, since the actuator of the switch 28 was stopped at the position just before it fell into the notch 27 of the cam 25, the rotation of the camshaft 22 resumed and the cam was stopped by the switch 37 at the notch 27 of the cam 25. When the thickness of the rattan 22 is zero, the switch 28 is switched, but the excitation of the solenoid 19 is held by the clear button signal and the number of times is connected. When the camshaft 22 resumes rotation, the switch 2 is in the engaged state.
The actuator 8 disengages the notch 27 of the cam 25 and the t switch 28 switches to ensure the energization of the solenoid 19 during the return of the camshaft 22 to the orientation layer.
Since there are no coins between the packaging rollers 10, 11, and 12, the switch 43 is pressed by the pin 81 while the roller 59 is in contact with the large cam surface 24 of the packaging control cam 24, and the switch 43 is pressed by the pin 81 when the clear button is operated. The paper feed roller 32 until the camshaft is returned to the orientation layer due to the switching state of
33 rotation stoppage is guaranteed. In FIG. 3, coins are fed from the rotating disk to between the wrapping rollers via a coin aligning tube 85 located downstream of the coin passage. This is a so-called cylindrical embodiment. In this embodiment, when the number of coins stacked in the coin collecting tube 85 reaches a predetermined number, the shutter device 8 located below the coin collecting tube 85
6 is opened, and the child's coins are placed on the child's coin support 87 located directly below this shutter device 86, and as the support 87 descends, they are brought together between the wrapping rollers 10, 11, and 12. It is now possible to do so.

Although this embodiment differs from the embodiment described above with reference to FIGS. 1 and 2 in the presence or absence of the coin aligning tube 85 and the shirt shutter device 86, other configurations are similar to those in FIGS. 1 and 2. Since this embodiment is almost the same as that of the embodiment, illustration and explanation of other configurations will be omitted. Next, the operation of this embodiment will be explained, but since the normal operation is the same as that of the above-mentioned embodiment, only the abnormal operation will be explained.

If the coins are distorted when the stacked coins are moved by the stacked coin support 87 from inside the coin alignment cylinder 85 to the packaging position in the packaging rollers 10, 11, 12 space, the packaging rollers 10, 1 1
, 12 cannot be moved to the regular clamping position, and the arm 52 cannot be moved to the regular clamping position.

Therefore, the switch 78 remains in the off state, and the motor 14 is stopped at a predetermined time. In addition, after a coin jams in the guide mechanism between the coin passage 2 and the coin alignment tube 85 or in the coin alignment tube, or after a predetermined number of coins are loaded in the coin alignment tube Z85, the shutter device 8
If the stacked coins are not fed between the wrapping rollers 10, 11, 12 because the wrapping rollers 10, 11, and 12 do not open, etc., the wrapping rollers 10,
Since the coins 11 and 12 move beyond the normal stacked coin fall landing position, they are pushed by the switch 43 and the pin 81 and the paper feed roller 3
The solenoid 42 for 2 and 33 is energized, and the friction roller 4
The zero rotation is not transmitted to the paper feed rollers 32 and 33, and paper feeding is not performed. To stop the paper feeding operation, the solenoid 19 (Fig. 12) is deenergized via the switch 37, and the camshaft 2
2 is stopped. As mentioned above, the coin wrapping machine according to the present invention focuses on the movement of the movable wrapping roller, and determines whether or not it has moved to the official vehicle model coin loading position when moving for stacking coin loading. Equipped with various detection means to detect whether the coin has moved excessively beyond the landing position, it is possible to detect an abnormal condition of the stacked coin between the wrapping rollers, and it can be This eliminates the inconvenience of having to carry out the regular packaging process even if a coin is in an abnormal state, and also provides an appropriate packaging control method to prevent damage to the winding needle, paper guide, and their movement mechanism. This has an excellent effect of making it possible to take
