Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper stack feeding device for a paper counting machine that supplies bundled bundles of paper sheets, particularly bundles of paper sheets, to a counting device one bundle at a time.

Conventionally, this type of banknote bundle supply device has a supply box provided in front of a banknote holder in which a large number of bundled banknote bundles are piled up horizontally with the wooden ends facing down and converged. The banknote bundle is advanced by a pusher driven by a spring or the like, and the end of the banknote bundle in the front row is pressed by a pusher piece located at the front end of the supply box and reciprocated in the longitudinal direction of the banknote bundle. It was used to feed banknotes one bundle at a time into a banknote holder (Special Publication Publication No. 49-48711). Incidentally, since counting of banknote bundles is done by suctioning the ends of the banknotes with means such as a suction head, alignment of the ends of the banknote bundles is required. Because it is fed by pressing in the longitudinal direction rather than the direction,
There was a problem in that the end of the banknote bundle was easily disturbed, causing problems in counting.

In this invention, a large number of bundled bundles of paper sheets are stacked one above the other with their front and back sides in contact with each other, and the bottom layer of the bundle of paper sheets is pressed against the wood edge by a pressing plate that reciprocates in the width direction. By adopting a completely new feeding mechanism that feeds the sheet bundle one by one to the sheet holder, the edge of the sheet bundle is not disturbed by feeding, which is convenient for counting, and the sheet bundle is not pressed by the pressing plate. It is an object of the present invention to provide a paper sheet stack feeding device for a paper sheet counting machine that is moved to a position by the weight of the remaining paper sheet stack, has a simple structure, and is economically advantageous, and in order to achieve this purpose, A pressing plate is provided on the bottom of the supply box so as to be able to reciprocate in the banding direction of the bundle of paper sheets, and the pressing plate pushes out the bundle of paper sheets one by one from the supply box along the banding direction. A paper leaf holder is provided to receive the paper leaf at a front position, and a suction head is further provided to suck and turn over the pushed-out paper bundle one by one while rotating around a shaft provided along the direction of the band. This is how it was done.

The details of this invention will be described below regarding a banknote bundle counting machine that implements this invention. Describing the overall outline with reference to FIGS. 1 and 2, the banknote bundle 13 bound in the width direction is placed in the supply box 1 of the banknote bundle supply device.
With the end of the supply box 1 in contact with a supply case 2 projecting diagonally upward at one end of the supply box 1, a large number of supplies are stacked one on top of the other with the front and back sides of each other stacked. The banknote bundle located at the lowest layer is fed one bundle at a time in the width direction by this feeding device, is supplied onto the banknote holder 3 of the next banknote bundle counting device, and is sucked by the rotation of this banknote holder 3. It is brought into contact with the head 4 and counted. The counted banknote bundle is
The banknote bundles that have been slid down along the slope of the banknote holder 3 to the sorting device and have been counted by this sorting device are arranged horizontally in the storage box 5 with the wooden ends facing down, and are placed in a predetermined count. Unmatched banknote bundles are discharged from outlet 6.

is started to rotate, and the rotating cylinder 27 is rotated via the V-belt. As a result of this rotation, the suction head 4 rotates around itself, and each time the bill bundle is attracted and turned over one by one as described later, a detection pulse is emitted from the detection head 29, and this detection pulse is passed through the gate 92 and counted. It is input to a circuit 93 and counted. The results are displayed on the display unit 94 shown in FIG. If the counts do not match, a signal is sent to operate a storage motor 70, which will be described later.

A sorting device is shown in FIGS. 2, 10 and 11, which receives counted banknote bundles from the banknote bundle counting device, stores banknote bundles that match a predetermined count, and discharges banknote bundles whose counts do not match from the discharge port 6. , 12. As shown in FIGS. 1 and 2, this sorting device is placed to the left of the counting device. The bottom plate 62 of the storage box 5, which stores banknote bundles that match a predetermined count, has a rectangular planar shape, and is attached to the frame 8 so as to be inclined to the left in FIGS. 2 and 15.
The left end side plate 63 is perpendicular to this bottom plate 62,
In other words, it protrudes above the left diagonal. Therefore, as shown in FIGS. 1, 2, and 15, this storage box 5 has a rectangular plane and a right triangular cross section in the width direction. The front end of the bottom plate 62 (second
Below the upper end (in the figure), a rotation shaft 64 is rotatably supported by the frame 8 in a diagonal lateral direction in accordance with the inclination of the bottom plate 62 in the width direction. A rotating plate 66 with a rectangular planar shape is attached to a pair of parallel arms 65, 65 fixed to both ends of this rotating shaft 64.
is attached with its longitudinal direction aligned with the width direction of the bottom plate 62. To explain the drive mechanism of the rotating plate 66, a sector gear 6 is located at the right end of the rotating shaft 64 in FIG.
7 is attached, and this sector gear 67 is connected to a pulley shaft 68 rotatably supported by the frame 8 via a reduction gear train (not shown).
A V-pulley 69 attached to the storage motor 70 is connected to a V-pulley 71 of a storage motor 70 via a V-belt (not shown). By rotating the storage motor 70 in the forward and reverse directions, the rotating plate 66 is rotated up and down. In order to control the rotation angle of the rotation plate 66, the rotation plate 66 is usually placed in a standby position (the solid line position in FIGS. 2, 10, and 15) and a retracted position (the first position).
A control switch such as a limit switch that detects the position of the rotary plate 66 and controls the storage motor 70 is provided around the position indicated by the two-dot chain line in FIG. In addition, in order to stop the rotary plate 66 at each of the above positions, the guide side plate 72 in front of the bottom plate 62 includes a bracket 73 and a bolt 74 screwed into the bracket, and the head of the bolt 74 connects the end of the arm 65. A pair of stoppers 75, 75 are provided around the right end of the rotation shaft 64 to stop the arm 6 at its distal end.
A hook-shaped stopper 76 is provided to stop the base of 5. Further, between the pair of arms 65, 65 at the front end of the bottom plate 62 (the right end in FIG.
is attached to cover the front end of the bottom plate 62 , and a stepped portion 80 is formed by the above-mentioned upper bent piece 78 of the guide plate 77 and the bottom plate 62 . A guide hole 79 is formed in the center of the bottom plate 62 in the longitudinal direction, and a paper receiving stand 81 is attached along the guide hole 79 so as to be slidable in the longitudinal direction of the bottom plate 62. That is, 83 shown in FIG. 12 is a leg part screwed into a recessed hole 82 at the bottom of the paper receiving stand 81, and this leg part 83 is inserted through a pair of blocks 84, 84 and a guide hole 79. Also, a guide piece 86 whose upper end is screwed between the blocks 84, 84, and a pair of rollers 85, 85 attached to the front and rear of the lower part, which contact the lower surface of the bottom plate 62;
It consists of a pair of leg pieces 87, 87 which are screwed to the left and right side surfaces of 4 and are in contact with the bottom plate 62. Bottom plate 62
A limit switch 88 is provided at the lower rear end (lower left end in FIG. 10) for detecting the retraction limit position of the paper receiving stand 81 and sending out a signal to disengage the camshaft clutch.

The operation of the banknote bundle supply device configured as described above will be explained. Activation of the main switch of switch group 96 (see FIG. 1) starts a cam motor (not shown). Next, as shown in FIGS. 2 and 3, a large number of banknote bundles 13 bound in the width direction are placed in a supply case 2 that projects diagonally upward, with the edges of the side to be counted touching each other. They are stacked face-to-face and diagonally vertically in the supply box 1. In this way, since the banknote bundles 13 are stacked with the end of the side to be counted at the bottom and in close contact with the supply case, the end of the side to be counted is also pressed against the side plate 9.
The butt ends are aligned. The above-mentioned end has been trimmed to make it convenient for counting. When the start switch (not shown) of the switch 96 is operated in this state, the vacuum pump (not shown) is operated and the camshaft clutch is engaged, so that the driving force of the cam motor is transmitted to the camshaft 21, and the cylindrical cam 22 is activated. be rotated. As the cylindrical cam 22 rotates, the supply arm 18 is rotated upward in FIG. 2, and along with this, the press plate 12 is sent upward from the standby position indicated by the solid line in the figure via the link 17. As the pressing plate 12 moves forward, the bundle of banknotes 13 stacked at the bottom in the supply box 1 is pushed in the width direction by the front end of the pressing plate 12 with the wooden end covered with a band, and the banknote bundle 13 stacked at the bottom in the supply box 1 is pushed through the front end of the pressing plate 12 in the width direction. The banknote is extracted and placed on the banknote support plate 30 located at a standby position tilted downward to the right as indicated by the two-dot chain line in FIG. Thereafter, as the cylindrical cam 22 rotates, the supply arm 18 is reversed downward in FIG. , one bundle of banknotes stacked on the banknote bundle falls, and the next banknote bundle is placed at the pressed position in front of the pressing plate 12.

As the cam plate 51 rotates, the banknote support plate 30 on which the banknote bundle 13 is placed as described above is rotated by the holder cam arm 44, the sector gear 46, and the pinion 4.
Similarly, as the cam plate 52 rotates, it is rotated upward via the transmission members of the paper presser cam arm 45, sector gear 47, pinion 42, and paper presser arm 36. rotated upwards. It presses the banknote bundle 13 together with the paper presser 37 and is rotated to the counting position tilted to the left as shown in FIG. At this position, the frontmost banknote of the banknote bundle 13 blocks the suction hole (not shown) of the suction head 4, so the vacuum switch 91 is turned on, thereby operating the counting mechanism as described above, and Since the engagement of the camshaft clutch is released and the driving force of the cam motor is not transmitted to the camshaft 21, the pressing plate 12 and the bill holder 3 are stopped in the above state. As the suction head 4 rotates, the bills are picked up and turned over one by one, and when the last bill is counted, the end of the bill bundle 13 is placed in the first
It will be in a bent state as shown by the two-dot chain line in Figure 4. At this time, the suction hole of the suction head 4 at the counting position is opened, so the vacuum switch 91 is turned off and the camshaft clutch is re-engaged. As a result, the cam plates 51 and 52 are rotated, and the banknote holder 3 is rotated downward in FIG. 14 via the transmission member.
The paper presser 37 is rotated upward to the position indicated by the dashed line.
Therefore, the banknote bundle 13 is released from the clamping between the banknote holder 3 and the paper presser 37, slides diagonally downward along the slope of the banknote support plate 30, and is sent to the next sorting device. Thereafter, the sheet holder 3 is returned to the standby position shown by the two-dot chain line in FIG. 5, and the paper presser 37 is rotated downward and returned to the position shown in the same figure.

When the verification circuit 95 of the counting mechanism confirms that the count of the banknote bundle 13 matches the predetermined count, the banknote bundle 13 slides onto the rotating plate 66 in the standby position, and the tip of the banknote The second plate hits the side plate 63.
It stops at the position indicated by the two-dot chain line in the figure. This stoppage is detected by means such as a limit switch, and the retraction motor 7 is
0 is started. The rotation of the motor 70 is transmitted to the sector gear of the rotating shaft 64 via the V-pulley 71, the V-belt, the V-pulley 69, and the reduction gear train, and the coaxial arm 65 is rotated upward. Along with this, the rotary plate 66 on which the banknote bundle 13 is placed is the tenth
Since the banknote bundle 13 is rotated until it reaches the storage position indicated by the two-dot chain line in the figure, the banknote bundle 13 is in a state where one side is placed against the paper receiving stand 81 with the wooden end facing down and is slightly inclined toward this stand 81 (the two-dot chain line in the figure ) is placed on the bottom plate 62. The paper receiving stand 81, which was initially positioned immediately in front of the stepped portion 80 of the guide plate 77, is pushed back by the rotating plate 66 each time the banknote bundle 13 is stacked one after another as described above. As a result, a large number of banknote bundles 13 have been counted.
are arranged horizontally in the storage box 5 with their wood ends facing down and their front and back sides in contact with each other. Rotating plate 6 reaches storage position
6 operates a control switch (not shown) at this position and rotates downward to reverse the retraction motor 70, and then operates another control switch at the standby position to stop the motor 70 and stop again at this position. . There is a stepped portion 8 between the guide plate 77 and the bottom plate 62.
0 is provided, so that the banknote bundle 13 stored in the last row does not fall toward the rotating plate 66 side. On the other hand, if the number of bills in the banknote bundle 13 does not match the predetermined count, or if air enters the suction hole of the suction head 4' during counting due to wrinkles in the banknotes, the vacuum switch 91 turns OFF and the counting stops. The above-mentioned situation is confirmed by detecting the discrepancy between the count of these banknote bundles 13 and the predetermined count by the collation circuit 95, and a signal is sent from the collation circuit 95 to the storage motor 70, so that the rotation is immediately started. Plate 66 is pivoted upward and placed in the retracted position. Vacuum switch 91 is turned off due to the above situation.
As described above, the paper presser 37 and the bill holder 3 rotate up and down, and the bill bundle 1 is
3 is sent from above the banknote holder 3 to the sorting device side, since the rotary plate 66 is in the storage position as described above, the banknote bundle 13 is dropped into the chute 10 (see Fig. 1) in the device, and is It is discharged from the discharge port 6 provided at the front of the counting machine. Even when this counter is used to count a bundle of relatively rigid paper sheets, air may enter from the suction head 4' during counting due to the rigidity of the paper sheets, causing the counting to stop. This sheet bundle is sent from the chute 10 to the discharge port 6 by the same operation. When the rotary plate 66 reaches the retracted position, the control switch is actuated as described above, and the rotary plate 66 is rotated in the opposite direction and returned to the standby position.

Conventionally, when moving a bundled bundle of paper sheets from the supply box to the counting device, the bundle of paper sheets in the supply box was moved in a direction perpendicular to the binding direction (lengthwise direction of the bundle of paper sheets) The width of the exit was adjusted using an adjustment plate so that only one bundle of paper sheets could pass through.

By the way, even if you adjust the width of the exit, if it is even slightly narrow, some of the sheets or band parts of the bundle of sheets will get caught on the tip of the adjustment plate.
It happened that the ends of the paper bundles were not aligned. In addition, if the exit is too wide, the binding direction and the moving direction of the bundle of paper sheets are perpendicular to each other, so the frictional force caused by the band of the first bundle may cause some of the sheets of the second bundle to be separated. This caused problems such as the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends of the ends were sometimes not aligned. This is because the free end (end) of the bundle of paper sheets coincides with the direction of movement, and the paper bundle is moving in a direction that disturbs the end.

However, in the present invention, the thickness of the pressing plate 12 is made thinner than the thickness of the paper bundle 13, and the moving direction of the pressing plate 12 is made to match the binding direction of the paper bundle 13. It is possible to move the wood end in an orderly manner without using a member that moves in a way that disturbs the wood end, and since the banded and restrained wood end is pressed by the pressing plate 12, the wood end can be moved. It can also be sent out in an orderly manner without any disturbance. Therefore, it is possible to eliminate the trouble of precisely adjusting the adjustment plate by hand as in the past, and still obtain accurate counting results.

As described above, the sheet bundle supply counting device of the present invention aligns the moving direction of the press plate with the binding direction of the sheet bundle, and the paper sheet bundle is placed on the restrained side (wood end) instead of the free end side (wood end). Since the paper sheet is pressed, the entire sheet bundle can be moved to the counting device in an orderly manner without disturbing not only the end but also the wood end of the sheet bundle. Therefore, much more accurate and reliable counting results can be obtained without having to manually adjust the size of the outlet of the supply box as in the past. In addition, it is possible to solve the problem of stopping the counting device due to the disturbance of the butt end, and to improve the efficiency of counting.

In addition, with this sheet bundle supply device, the movement of the sheet bundle to the pressed position by the pressing plate is performed by pulling out the lowest layer of sheet bundles with the pressing plate and causing the remaining sheet bundles to fall under their own weight. Since it is mounted on a table, a moving device or the like is not required, and the structure is simple and inexpensive.
