Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper sheet binding device for applying tape to bundles of paper sheets such as paper sheets, slips, etc.

Currently, as shown in FIG. 2, the method for sealing paper sheets is to fold the tip of the sealing tape 1 into the middle of the side edge (the surface where the overlapping sheets are visible) of the paper bundle 3, and A common method of sealing is to wrap tape 1 by rotating tape 1 once, then cut tape 1 and heat-bond a portion of the end. In the case of continuous sealing using this method, as is clear from Figure 2, the amount of tape 1 required varies depending on the height of the paper sheets, and marks, characters, etc. are printed on tape 1 in advance. If the printed portion does not appear at a predetermined position on the stack of paper sheets, a shift will occur (Here, it is assumed that the thickness t of the stack of paper sheets 3 is constant. The same applies hereinafter). If such a situation occurs, not only will the purpose of display not be completely achieved, but also the printed portion will not appear at the predetermined position during the stamping operation performed after sealing, which is undesirable.

The present invention solves the above-mentioned drawbacks, and even when multiple types of paper bundles of different heights are successively sealed using the tape, the printed portions of the tape such as marks and characters always remain on the paper. To provide a paper sheet binding device which allows a bundle of leaves to appear at a predetermined position without being shifted.

In carrying out the present invention, first, the tape length necessary for sealing a bundle of paper sheets with the maximum height among the various types of paper sheets to be targeted is determined in advance, and marks are placed at each interval. It is necessary to print characters 2 and matching marks a, b, c, etc. Then, the matching marks are attached in the number corresponding to the type (size) of the bundle of paper sheets to be bundled. To explain paper failure as an example, if 100 yen bills, 1000 yen bills, and 500 yen bills are tied together in 100 pieces, the match mark will be placed on paper sheets for each denomination. As shown in the third diagram, matching marks a, b, and c are attached in the order of height, that is, 10,000 yen, 1,000 yen, and 500 yen. Further, the display position of the printing section 2 for the bank name, etc. is necessarily determined by the size of the paper bundle in relation to the display positions of the matching marks a, b, and c. These relationships will be described later.

The present invention has been achieved on the premise that the above-mentioned tape is used, and its configuration is as follows:
The tape is fed out by a feed roller, the tip of the tape is inserted between the sheets by a tape insertion plate, the tape is wound around the sheet bundle by rotating the sheet bundle, and after cutting the tape, the end is inserted between the sheets. In a binding machine that binds paper sheets by thermocompression bonding, the tape has a plurality of match marks corresponding to the height of the bundle of paper sheets to be bound, and a predetermined interval from the match mark. A motor-driven feed roller and a A tape feeding device consisting of a pressure roller biased toward the roller by a spring, a matching mark detection device located on a tape feeding path and detecting matching marks on the tape and emitting a pulse signal, and a sheet bundle. a bill height regulating member provided at the bundling position to regulate the position of the side edge of the bill holder, and a bill holder that raises the upper end surface of the bundle of paper sheets placed on the bill holder until it abuts against the bill height regulating member. A stand device, a height signal generator that detects the movement of a height detection plate linked to the bill receiving stand device and emits a pulse signal according to the height of the stack of paper sheets, and this height signal generator. and a comparator that inputs the pulse signal from the match mark detection device and compares the match/mismatch between the two, and controls the motor of the tape feeding device with an output signal based on the comparison result to control the paper sheet. This paper sheet binding device is characterized in that the amount of insertion of the leading end of the tape into the gap is adjusted so that characters and the like attached to the tape can always be displayed at a predetermined position.

Next, an embodiment of the present invention will be described, but before explaining the apparatus, the tape will be explained.

For convenience, we have set three types of paper sheets with different heights as objects for wrapping, and we will call them large paper leaves, medium paper leaves, and small paper leaves in descending order of height.
As shown in Figure 2, if the height of a large paper bundle is h and the thickness is t, and the thickness t is assumed to be the same as the thickness of all types of paper bundles, then the tape required for sealing is The length of tape 1 is A-B-C-D-E-F-G-H-I-J, and point G on tape 1 is the midpoint between F and H, and a part of the tape is thermally bonded. The tape length between I and J is made to be approximately constant for all types of paper bundles.
On the tape 1, a match mark a for large paper leaf bundles is printed in the middle of the interval of the tape length A-J required for sealing large paper leaf bundles, and after sealing, the printed part 2 of the bank name etc. By arranging and printing the printing unit 2 at a position related to the matching mark a so that the center of the mark coincides with point G, the center of the printing unit 2 will always be aligned when sealing a large bundle of sheets. It will coincide with the midpoint of the height h, and the purpose of display will be fully achieved. In addition, the tape 1
When sealing inner leaf bundles and small paper leaf bundles using
If the height of the inner leaf bundle is h' and the height of the small leaf bundle is h'', then after sealing, the difference between h and h' is Y', the difference between h and h'' is Y'',
h>h′>h″, Y′<Y″, and the center of printing section 2 is
They do not match the midpoints of h′ and h″, and there is an upward shift of 1.5Y′ for the inner leaf bundle and 1.5Y″ for the small leaf bundle, which means that When an inner leaf bundle and a small leaf bundle are sealed between D and G of tape 1 in a large leaf bundle, between D and E, the inner leaf bundle is Y', and the small paper leaf bundle is Y'. ”, and F-
This means that the required length of the tape 1 decreases by 0.5Y' and 0.5Y'' between G.

Therefore, in order to align the center of the printing unit 2 with the midpoint of h' and h'', the distance between A and D of tape 1 in the large sheet stack is 1.5Y' for the inner sheet bundle, and 1.5Y' for the small sheet bundle. Then, if you fold an extra 1.5Y'' into each stack of sheets, the center of printing section 2 will always align with the midpoint of h' and h'', and the purpose of display will be completely achieved. Set the alignment mark b for the leaf stack and the alignment mark c for the small stack of leaves at intervals of 1.5Y' and 1.5Y'' from the alignment mark a for the large stack of leaves, respectively, in the traveling direction of tape 1. If you place and print the tape 1 away from the rear, and stop feeding the tape 1 at match mark b for the inner stack of leaves and match mark c for the small stack of leaves,
The feeding amount of tape 1 is increased by 1.5Y′ for the medium leaf bundle and 1.5Y″ for the small paper leaf bundle compared to the large paper leaf bundle.
The increased amount is also folded into each sheet bundle.

In this way, the difference in the amount of tape 1 required due to the difference in the height of each bundle of paper sheets is absorbed by the folded part at the tip of the tape, and even when bundles of paper sheets of different heights are successively sealed, The midpoint of the height of the stack of paper sheets coincides with the center of the printing section 2 of the bank name, etc.

Next, the embodiment shown in FIGS. 3 to 5 will be described.

Load the paper bundle 3 onto the bill tray 4, and
When the tip of the tape presses a switch (not shown) at the rear of the bill tray 4, the motor M1 of the tape feeder T is activated.
is supplied with power, and the gear 6 is fixed to the rotating shaft 5 of the motor M1, and the gear 9 is connected via the idle gear 7.
, the tape 1 held between the feed roller 8 and the pressure roller 10 in the tape feed device T is fed onto the paper bundle 3 in the direction of the arrow.

A lamp 11 in a match mark detection device S and a photosensitive element 12 for detecting the light emitted from the lamp 11 are visible in the path of the tape 1, and the light emitted from the match mark detection device S is blocked by the match mark. The pulses for the number of times are transferred to the shift register R shown in FIG.
It is now sent to 1.

Also, a pressure contact lever 14 that swings around the shaft 13
A pressure roller 10 is rotatably supported at one end, and a tension spring 15 is connected to the other end, giving the pressure lever 14 a tendency to rotate counterclockwise about a shaft 13. The pressure roller 10 is brought into pressure contact with the feed roller 8, and the pressure roller 10 is separated from the feed roller 8 by swinging the pressure lever 14 clockwise by energizing a solenoid 16. Therefore, when the tape 1 is fed out and the match mark a for the large sheet bundle blocks the light emitted from the match mark detection device S, the shift register R1 shown in FIG.
An electric circuit is configured to send one pulse to the motor M1, energize the solenoid 16, cut off the power supply to the motor M1, and stop feeding the tape 1.

Next, the height signal generating device
When the bill tray cam lever 19 starts rotating, the bill tray cam lever 19
A bill holder block 20 holds the bill holder 4 horizontally.
A compression spring 22 inserted into the lower end of the bill holder block 20 always applies an upward pressing force to the bill holder 4, and one end of the bill holder cam lever 19 The rise of the bill tray cam 18 is regulated by the contour of the bill holder cam 18 via a cam roller 23 provided at the top.

Therefore, as the camshaft 17 rotates counterclockwise, the bill holder cam 18 rotates in the same direction, and the cam profile that contacts the cam roller 23 suddenly changes from an arc to a flat shape due to the rotational movement. When shifting, the bill holder cam lever 19 rotates counterclockwise about the cam lever shaft 24, and the bill holder block 20 connected by the link 21 starts to rise due to the pressing force of the compression spring 22. When the upper end of the stack of paper sheets 3 comes into contact with the bill height regulating member 27 fixed to the chuck board 25 at a position where the stack of paper sheets 3 is lightly held, the rise of the stack of paper sheets 3 and the bill receiving block 20 is prevented. The bill holder cam 18 is disconnected from the bill holder cam 18, and the stopping positions of the bill holder 4 and the bill holder cam lever 19 are regulated by the height of the stack of paper sheets 3.

Further, a height detection plate 28 for the stack of paper sheets 3 is connected to the other end of the bill receiving cam lever 19, and a lamp 29 and a light emitted from the lamp 29 are detected by sandwiching the height detection plate 28. Sensing elements 30 are installed facing each other, and the height is set so that light is blocked by the height detection plate 28 at the initial position of the bill tray cam lever 19, that is, when the stack of paper sheets 3 is loaded into the bill tray 4. The signal generator X is configured.

The height detection plate 28 moves counterclockwise to the cam lever shaft 24 as the bill holder cam lever 19 operates.
The lamp 29 and photosensitive element 30 of the height detection plate 28 swings around the center and can be stopped at a position corresponding to the height of the stack of paper sheets 3, which varies depending on the height of the stack of paper sheets 3.
There are 3 slits for each bundle of paper sheets at the stop position.
There are slits for large paper leaf stacks from the bottom.
a', a slit b' for the inner sheet bundle, and a slit c' for the small sheet bundle.

When the height detection plate 28 stops at a position corresponding to the height of each bundle of paper sheets, the height signal generator pulses are sent to shift register R2, and the number of pulses already sent to shift register R1 from matching mark detection device S is compared with the number of pulses sent to shift register R2, and as shown in FIG. When matched, solenoid 16
The motor M1 remains energized and is not supplied with power, so that the tape 1 is no longer fed.

Furthermore, when the numbers of pulses sent to the shift registers R1 and R2 do not match, either or both of the match marks b and c shield the match mark detection device S, so that the pulses sent to the shift register R1 become height signals. The energization of the solenoid 16 is cut off until the number of pulses already sent to the shift register R2 from the generator X matches, and the motor M
The electric circuit is configured such that power is supplied to the motor M1 to further feed out the tape 1, and when a match is made, power is applied to the solenoid 16 to cut off the power supply to the motor M1 and stop feeding out the tape 1.

That is, after the tape 1 is fed out until the matching mark a blocks light from the matching mark detection device S, the slit a' reaches the height signal generating device Since the number of pulses sent to the shift registers R1 and R2 are one each and match, the motor M1 will not be restarted and if the sealing is performed in this state, the center of the printing section 2 will be will coincide with the midpoint of height h.

In addition, in the case of the inner sheet stack, when the bill tray 4 stops rising, two pulses from the slits a' and b' are sent to the shift register R2, and the match mark that has already been sent to the shift register R1 is sent to the shift register R2. Since the value does not match the one pulse caused by a, solenoid 16
When the power is cut off, the motor M1 restarts, and one pulse is sent due to the match mark b.
When two pulses sent to shift registers R1 and R2 match, solenoid 1
6 is energized, motor M1 stops, and tape 1
The length from match mark a to b, that is, 1.5Y', is increased compared to the large bundle of sheets and sent out. It is folded into the inner sheet bundle, and the center of the printing section 2 coincides with the midpoint of the height h.

For small leaf bundles, the slits a', b',
Three pulses from c' are sent to shift register R2, and match marks b, c are sent to shift register R1.
Tape 1 is fed out until two pulses are sent, and when the numbers of pulses sent to shift registers R1 and R2 match, with three pulses each,
The tape 1 will be folded into the stack of small sheets an extra 1.5Y, and the center of the printing section 2 will coincide with the midpoint of the height h''.

Next, to explain the sealing operation after the tape length corresponding to each paper bundle is fed out and the tape feeding device T is stopped, the tape insertion plate 31 descends and the tape 1 is placed in the middle part of the upper end of the paper stack 3. At the end of the folding and rising, the chuck plate 25 is closed and the tape 1 is folded into the bundle of paper sheets 3, and then it rotates clockwise once while firmly tightening, wraps the tape 1 around each sheet, stops, and then , moving cutter 32
moves to the fixed cutter 33 side on the left and tape 1
The tape 1 is thermally bonded by pressing the chuck plate 25 from above the tape 1 around which the heater 34 and the block 35 are wound, completing a series of sealing operations starting from the tape feeding operation.

As described above, the present invention provides a banding tape feeding device that uses a motor, a matching mark detection device that uses a photosensitive element to detect matching marks that are printed on the tape at regular intervals, and a stack of paper sheets that is fed into the tape. It consists of a height signal generator that generates an electric signal according to the height of the stack of paper sheets in conjunction with a bill tray that moves the side edge of the paper stack to a specified position. Compares the mark detection signal and the height signal generated by the height signal generator to control the motor of the tape feeding device and adjust the amount of tape feeding, as well as the amount of folding of the tape tip during sealing. By doing this, the center of the printed part of the bank name, etc. printed in the position related to the matching mark can always be aligned with the center position of the height of the stack of paper sheets. Even when sealing many types of paper sheets, the center of the printed part of the bank name, etc. can be reliably aligned with the center of the height of the paper sheet, and the purpose of display can be completely achieved. Even during the later stamping operation, the printing part appears at a predetermined position and the stamping operation can be carried out properly, so that it can be carried out suitably.
