Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a paper sheet binding device for bundling stacked paper sheets using a binding tape.

[Conventional technology and problems]

Conventionally, tapered guide members have been used to bundle paper sheets of a predetermined shape such as banknotes, securities, and other various cards.
Insert the binding tape between the sheets of paper, and then insert the binding tape between the sheets spread by the guide member, so that the tip of the binding tape bites between the sheets and is held.
After that, after the guide member is pulled out, the holding plate holding the paper sheets is rotated to wrap a binding tape around the paper sheets, and the end of the roll is glued to bind the paper sheets. Similar binding devices are known.

In this paper sheet binding device, the binding tape is wrapped around the paper sheets in a taut state.

This binding tape has the name of the bank on the front side and an adhesive for thermal bonding on the back side, and the heater usually comes in contact with the surface of the tape wrapped around the paper sheets. The rolled tapes are then thermally bonded together using an adhesive.

By the way, this binding tape is loaded in advance into the tape supply section of the binding device by the operator as shown in FIG.
If you insert the tape in the opposite direction or twist it in the opposite direction as you pass the tape through its path, the adhesive-coated back side of the tape will be wrapped outwards from the paper. When the heater is thermally bonded, the adhesive melts onto the heater itself due to the heat, and there is a problem that the adhesive cannot be properly bonded even if the heater is wound normally next time.

(Means for Solving the Problems) The paper sheet binding device of the present invention includes a tape mark detection sensor that detects tape marks printed at predetermined intervals on the tape fed from the tape supply section, and a The above tape mark detection sensor while being fed over the length of
The present invention is characterized by comprising a control section that prohibits the bundling operation of the bundle of paper sheets unless the tape mark is detected even once.

[For production]

By attaching a mark to the surface of the binding tape and detecting this mark, it is possible to prevent the tape from being wound upside down and bonded.

FIG. 7 shows the control system of the counting and tying machine shown in FIG. In the same figure, 61 is an overall control unit, 62 is a memory unit that stores various data such as counting data, and the overall control unit 6
2 is the already mentioned feeding section 4, operation section 6, and operation/display section 8.
, the identification section 10, the accumulation section 18, and the transport and sorting section 24. The overall control section 61 is also connected to a bundling control section 51, which will be described later.

The binding control unit 51 is composed of a microcomputer, and drives and controls the binding device according to a predetermined program.

Reference numeral 52 denotes a first drive unit that rotationally drives the pulse motor M1, and receives a rotation pulse P1 (designating a pulse rate) from the control unit 51 and a rotation direction signal M1-R.

Ml-1 (specifying the rotational direction), the pulse motor M1 is rotated in the forward direction according to a rotation direction signal M1-R that drives the pulse motor M1. This causes the delivery roller 34 to rotate counterclockwise in FIG. 4.

M2 is a pulse motor that rotationally drives the holding plate 32-1, 32-2, and is driven by a second drive unit 54 that receives a rotation pulse P and rotation direction signals M-R and M2-L from the control unit 51. According to the rotation direction signal M-R,
When the pulse motor M2 is rotated forward, the holding plate 32-1.3
2-2 rotates counterclockwise in FIG.

The cutter drive unit SD1 receives a drive signal S from the control unit 51.
1 by cutter drive unit r! The solenoid in 140 (FIG. 4) is actuated, thereby pivoting the cutter 39 to the position shown in phantom in FIG.

The adhesion drive section SD2 operates a solenoid or the like in response to a drive signal S2 from the control section 51 to cause the adhesion device 41 to protrude and come into contact with the tape on the holding plate 32-1.

The bill splitting drive unit SD4 operates the bill splitting device 33 using a solenoid or the like. The bill splitting device 33 is normally protruded to the tape winding position by a spring (not shown) as shown in FIG.
When the bill splitting drive section SD4 operates a solenoid or the like in response to a drive signal S4 from the control section 51, the bill splitting drive section SD4 moves it to the left in FIG. That is, the bill splitter @33 is pulled out from the state where it is inserted into the paper sheet and released.

55 is a part of the sensor that detects the operation of each mechanism of the binding machine,
A detection signal is given to the control section 51. The control unit 51 checks the operation of each mechanism based on the detection signal, and determines the content and timing of the drive signal and the like.

The counting operation and the bundling operation will be explained below with reference to FIGS. 8 and 9, but these two operations can be performed in parallel.

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

When the device is in a standby state, when any of the denomination switches DNK is pressed (102), the corresponding denomination flag in the memory section 62 is set (104), depending on the selected mode. (106), and sets the appropriate flag (108.110). After that, when the clear start switch CTR is pressed (112), the memory section 6
Please clear the banknote counting memory and batch memory in 2.11
4) After confirming with the sensor 5EN2 that there are no banknotes in the stacking section (116), the process proceeds to step 118. If the clear start switch CTR is not pressed (when the restart switch RTR is pressed (113), the process immediately proceeds to step 118.

In step 118, a check is made to see if the tape alarm flag is on. If it is not turned on, it immediately starts feeding out (120). If it is on, wait until the restart switch RTR is pressed (or pressed again when step 118 is reached via step 113) (122), and start feeding (120).

The dispensed banknotes are identified one by one by the identification unit (124>).

As a result of the identification, if it is necessary to eliminate (126), it is guided to the first discharge section (128).

Also, if it is a different denomination, (130). Guided to the second discharge section (132). If neither of these is the case, that is, if the corresponding denomination is normal, 1 is added to the contents of the batch memory (134). In other words, count.

If it is in the counting mode (136), after confirming that there are still banknotes in the feeding section (138), step 12
Return to 4. When there are no more banknotes in the feeding section, that is, when all the banknotes have been counted, stop feeding (140
),finish.

If it is not counting mode but counting/binding mode (13
6), the count value stored in the batch memory is rl 00J
It is determined whether the value has been reached (142). If the banknotes have not been reached yet, it is then determined whether or not there are banknotes in the feeding section (144), and if so, the process returns to step 124. If not,
To stop feeding (146), to generate a fractional alarm (1)
48), end.

When the count value reaches 100 (142), stop feeding (150), clear batch memory (152),
The counted banknotes are transferred to the binding section (154). When this transfer is completed, the banknote bundle is transferred to the holding plate 32-1.3 as described below.
2-2, and when the transfer member 31 returns to its original position,
A binding operation starts at the binding section. On the other hand, in the counting section, if there are still banknotes in the feeding section (156), step 12
Return to 0 and restart counting. When there are no more banknotes in the feeding section (156), the process ends.

Next, the binding operation will be explained with reference to FIGS. 9(a) to (Q).

A bundle of paper sheets counted in a predetermined number, for example, 100 sheets, is placed on the transfer member 31 and is linearly transferred to the left in FIG. 4, hitting the backing plate 42 (FIG. 8, 154). At this time,
Bill splitting device! 33 protrudes at the tape winding position (the state shown in FIG. 3), so the paper sheet is split into two as shown.

The control section 51 outputs a rotation direction signal M1-R and a rotation pulse P1, and the first drive section 52 supplies a pulse in the normal rotation direction to the pulse motor M1. Therefore, the pulse motor M1 rotates normally, and the feed roller 34 is driven by the pulse motor M1 to rotate normally (counterclockwise in FIG. 4). Therefore, the tape is sent to the feed roller 34, and the leading end of the tape is inserted between the bundles of paper sheets split by the bill splitting device 33. After stopping the pulse motor M1, the control part 5
1 generates a drive signal S4, and in response to this, the bill splitter drive unit S
D4 moves the bill splitting device 33 to the left in FIG. 1 and separates it from the bundle of paper sheets. Next, the holding plates 32-1 and 32-2 move toward the bundle of paper sheets and clamp the bundle of paper sheets. Note that the transfer member 31 and the holding plates 32-1 and 32-2 are provided so as to contact the paper sheets at different positions in the longitudinal direction of the paper sheets (direction perpendicular to the plane of the paper in FIG. 4). Therefore, the retaining plate 32-
1.32-2 does not hit the transfer member 31 even if it moves to the position where it clamps the paper sheet.

After the holding plates 32-1 and 32-2 have held the paper sheets, the transfer member 31 moves to the right from the tape winding position rllD. As a result, the state shown in FIG. 9(a) is reached.

Next, the pulse motor M1 starts rotating normally again, and after a short delay, the pulse motor M2 starts rotating normally.

In order to rotate the pulse motor M2 in the normal direction, the control unit 51 generates a rotation pulse P and a rotation direction signal M2-R, and the second drive unit 54 receives these and supplies normal rotation pulses to the pulse motor M2. . As a result, the holding plate 32-1.32-
2 rotates counterclockwise as shown in FIGS. 9(b) to 9(d).

The pulse motor M1 stops when it reaches the state shown in FIG. 9(1)). Thereafter, the supply of the rotation pulse P1 is stopped, and the application of braking force to the tape by the pulse motor M1 is started. In this way, even if braking force is applied, Fig. 9(b)
If the tape is in this state, the tip of the tape inserted into the bundle of paper sheets is bent at a substantially right angle, so it will not come off from the bundle of paper sheets. Therefore, the tape can be tightly wrapped around the bundle of paper sheets in a taut state. As will be described later, the application of the braking force is continued until the rotation of the holding plates 32-1 and 32-2 is completed and the tape is removed by the cutter 39. The forward rotation of the pulse motor M2 continues until the state shown in FIG. 9(d) is reached.

Although Figure 9 shows the case where the tape is wound once,
It is also possible to wrap the tape two or more times.

After stopping the pulse motor M2, the control m+ section 51 outputs the drive signal S.
1, the cutter drive unit SD1 operates the cutter drive device 40, and the cutter 39 rotates to cut the tape as shown in FIG. 9(d).

At the same time, the pulse motor M1 switches from an operating state in which it generates a braking force to an operating state in which it pulls the tape in the opposite direction. That is, the control section 51 controls the rotation pulse P and the reversal signal M.
1-L, and the first drive section 52 supplies a pulse in the reverse direction in response to this. In this way, the pulse motor M1 tries to rotate the feed roller 34 clockwise, which increases the tension on the tape and makes cutting of the tape more reliable.

At approximately the same time or slightly delayed from cutting the tape, the control section 51 outputs the drive signal S2, the adhesive drive section SD2 is activated, and the adhesive section 41 moves to the position shown in FIG. 9(e), and the built-in The tape is thermally bonded using a heater. Next, the 9th
As shown in Figure (f), the stamping device 43 operates and stamps a confirmation stamp on the tape.

After that, the pulse motor M2 reverses, and the holding plate 32-1
．． 32-2 is rotated clockwise and stopped when it reaches the state shown in FIG. 9 (9).

Thereafter, a paper sheet take-out device (not shown) takes out the bundled paper sheet bundle from the holding member 32-1, 32-2. Accordingly, the holding plates 32-1 and 32-2 return to the position shown in FIG. 4. The bill splitting device 33 is a tape-wrapped bag fat.
It protrudes to D in preparation for transporting the next bundle of paper sheets.

Above, we have explained the case where the tape T is being supplied normally, but if the supplied tape is upside down,
This is detected based on a signal from the tape mark sensor 53, and tape supply and tape winding are stopped.

That is, the bank name NBK, etc. is printed on the front side of the tape, as shown in FIGS. 6(a) and 6(b), respectively, and the bank name is placed at a predetermined position on the banknote bundle. A tape mark TMK is printed on it. on the other hand,
A heat-sensitive adhesive is applied to the back side, and the tape mark TMK is not visible from the back side. Therefore, the tape mark TMK is not detected by the tape mark sensor 53. In addition, if the tape mark is provided only on one edge in the width direction of the tape as shown in Figure 6(a), when the tape is turned over, the tape mark will be on the opposite side in the width direction. will be located. Therefore, in this case, even if the tape is transparent or semi-transparent, the tape mark TMK is not detected by the tape mark sensor 53. Feeding roller 3
4 and inserting the tip of the tape between the stacks of paper sheets, and when rotating the roller 34 in conjunction with the rotation of the holding plates 32-1 and 32-2 to feed the tape, If no tape mark is detected, it is determined that the tape is upside down.

For this purpose, as shown in FIG.
is programmed to perform a timekeeping operation while the motor M1 is rotating, and to have a timer function that is reset when a tape mark is detected. When it is determined that the tape is upside down, the tape supply and tape winding are not stopped or prohibited, and an alarm is displayed to notify the operator of the abnormality. Note that the banknote counting operation may also be interrupted, or may be interrupted after counting until 100 banknotes are counted and stacking them in the stacking section.

The operator confirms that the tape is turned over and restores the tape to its normal state. Then, remove the banknote bundle from the bundling section, reload the banknotes into the banknote loading slot, and press the restart switch R.
Press TR to restart counting and tying.

In the above example, a timer that counts during the rotation of the motor M1 detects turning over, but a photo sensor or the like is used to detect the rotation of a protrusion provided on a rotating body that rotates together with the motor M1. If no tape mark is detected during a predetermined number of detections by the photosensor from the start of the bundling operation, it may be determined that the tape has been turned over.

Furthermore, it has been explained that the tape mark used is a mark used to position the bank name at the center of the width of a bundle of banknotes. There are some that have been disclosed. In this application, marks are printed in advance on the tape at positions related to bank names at regular intervals, and a mark sensor detects the marks and stops feeding the tape, thereby determining the tape winding start position. It is set at a fixed position in relation to the position of the printed part of the bank name, so that when the tape is wound around the stacked banknotes, the central part of the printed part of the bank name is positioned in the height direction of one side of the stacked banknotes. Match the center of the
Furthermore, it is disclosed that the cutting position of the tape is made constant in relation to the position of the printed part of the bank name, but the mark used for the above purpose may also be used to detect when the tape is turned over. Well, it's convenient.

Note that the present invention is not limited to the binding machine having the structure shown in FIG. 4; for example, a structure in which the paper sheets are kept stationary and the tape is rotated around the bundle of paper sheets to be wound. It can also be applied to things like It can also be applied to machines that only bind together without a counting function.

[Effects] As described above, according to the present invention, it is possible to prevent adhesive from adhering to the heater, and there is no need to remove adhesive from the heater.

If there is a device that counts and ties the tape as shown in the example, it will automatically prevent a large amount of tape from being tied inside out continuously, and it will also prevent a large amount of adhesive from being attached to the heater itself. There is no need to replace the heater.
