DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper bundle in which a bundle of tapes is wound around a bundle of small bundles of 100 sheets bundled in a predetermined number of bundles to form a large bundle. The present invention relates to a large leaf bundling machine.

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open Nos. 2-180114 and 4-20181 disclose a large-bundling apparatus for binding paper sheets by winding a binding tape around a small bundle group having a predetermined number of bundles.
No. 0 is known. JP-A-2-180
The large bundle of paper sheets binding machine disclosed in Japanese Patent Publication No. 114 is configured to place a small bundle group of a predetermined number of bundles on a table with its longitudinal direction being horizontal, and in this state, the tape supply means binds the small bundle group to the small bundle group. After the supply of the binding tape, the binding tape is rotated around the small bundle group by rotating the binding tape together with the table in a state sandwiched between the small bundle group by the clamp means. After that, the overlapping portion of the binding tape wound around the small bundle group is thermocompression-bonded, and the portion after the thermocompression bonding portion is cut off, thereby winding the binding tape around the small bundle group along the longitudinal direction. is there. Then, after that, the position changing mechanism automatically changes the orientation of the small bundle group on the table from the posture in which the longitudinal direction is horizontal to the posture in which the short direction is horizontal, and thereafter, the winding operation of the binding tape described above. Is repeated, the binding tape is wound around the small bundle group along the lateral direction, and thereby a large bundle formed by binding a predetermined number of small bundle groups into a cross can be created.

[0003] On the other hand, a large sheet bundle binding machine disclosed in JP-A-4-201810 does not wind the binding tape by rotating the table as described above, but holds the leading end of the binding tape. By moving the tape sandwiching mechanism along the periphery of the holding mechanism for holding the small bundle group, the binding tape is wound around the small bundle group, and after the winding of the binding tape, As in the above-mentioned publication, the overlapping portion of the binding tape wound around the small bundle group is thermocompression-bonded by an adhesive cutting means, and the portion after the thermocompression bonding is cut. Also, in this large sheet bundle binding machine, the binding tape is not wound at the loading position where the small bundle group is loaded, but the small bundle group loaded at the loading position at the binding position on the rear side of the machine. Is moved to wind the binding tape.

[0004] In this large sheet bundle bundling machine, a binding tape is wound around the small bundle group in the longitudinal direction, and then the direction of the small bundle group on the table is changed by an operator. Convert the horizontal direction from the horizontal position to the horizontal position, and then repeat the above-described binding tape winding operation to wind the binding tape around the small bundle group in the short direction, This makes it possible to create a large bundle formed by binding a small bundle group having a predetermined number of bundles into a cross. In addition, when the binding work of the cross is completed, the stamping means is driven so that the surface of the binding tape is stamped.

[0005]

In the above-described large-bundling apparatus for paper sheets, when binding small bundles, an operator usually places 10 small bundles on a table. However, counting the number of bundles at this time is left to the operator, and therefore, even if the operator starts the binding operation with the small bundles erroneously counted, the large bundles are counted. Is created, and furthermore, there is a problem that a seal indicating that the number of bundles is 10 is automatically performed.

The present invention has been made in view of the above circumstances, and it is possible to confirm the number of bundles before the binding operation, and if necessary, if the number of bundles is other than the predetermined number of bundles. It is an object of the present invention to provide a large-size sheet bundle binding machine in which a seal is not performed.

[0007]

In order to achieve the above object, according to a first aspect of the present invention, there is provided a loading section in which a small bundle group is loaded, and a holding means for holding the small bundle group loaded in the loading section. And a binding means for winding a binding tape around the small bundle group clamped by the clamping means and binding the bundle tape.

According to a second aspect of the present invention, in the first aspect, there is further provided a marking means for marking the binding tape bound to the small bundle group when the binding operation by the binding means is completed. Features.

In a third aspect based on the first aspect, when it is confirmed by the number-of-bundles counting means that a small bundle group having a predetermined number of bundles is not loaded, it is determined that the number of bundles does not match. A notifying unit for notifying is further provided.

According to a fourth aspect of the present invention, in the third aspect, an instruction signal for binding the small bundle groups in the bundle number mismatch state when the notification unit notifies the bundle number mismatch state. The binding control means starts the binding operation by the binding means when an instruction signal is output from the operating means.

In a fifth aspect based on the fourth aspect, when the binding operation by the binding means is completed, the binding control means performs marking on the binding tape bound to the small bundle group with respect to the marking means. It is characterized in that it is prohibited to make it.

According to a sixth aspect of the present invention, in the first to sixth aspects, the number-of-bundles counting means is constituted by a sensor that scans a banded portion of a small bundle loaded in the loading section.

[0013]

According to the first aspect, the binding operation by the binding means is performed.
Before, based on the counting result of the bundle number counting means, it is confirmed whether a small bundle group of a predetermined bundle number set in advance is loaded,
When the loading of the small bundle group having the predetermined number of bundles is confirmed, the binding unit is started to perform the binding operation. The binding tape is prevented from being wound around the bundle without confirmation. In addition, the bundle counting means
In the state of being loaded in the part and being clamped by the clamping means
Just before binding to count the number of small bundles
Can be counted.

According to the second invention, when the binding operation by the binding means is completed, the marking means causes the binding tape bound to the small bundle group to be marked.
Since the seal is pressed on the binding tape, it can be confirmed that the small bundle of the small bundle group has a predetermined number of bundles.

According to the third invention, when it is confirmed by the bundle number counting means that the small bundle group having the predetermined number of bundles is not loaded, the notifying means notifies that the bundle number does not match. Therefore, the operator can confirm that the abnormality has occurred.

According to the fourth aspect of the invention, when the notification unit notifies that the number of bundles does not match, the operation unit further instructs the small bundle group in which the number of bundles does not match to be bundled. Is output, the binding control unit causes the binding unit to start the binding operation.
Even if the small bundle groups are in a bundle number mismatch state, the small bundle groups can be bound.

According to the fifth aspect, when the binding operation by the binding means is completed, the binding control means prohibits the marking means from marking the binding tape bound in the small bundle group. Therefore, no stamping is performed on the bundled small bundles in the bundle number mismatch state, and the distinction from the bundled small bundles with the normal bundle number can be made clearly.

According to the sixth invention, the bundle number counting means is constituted by a sensor which scans the banded portion of the small bundle loaded in the loading section. The delimited part can be determined as the boundary of the small bundle.

Next, a description will be given of the number-of-bundles counting means 9, the notifying means 10, and the binding control means 100 connected thereto, according to the features of the present invention. The number-of-bundles counting means 9 is shown in FIG.
As shown in (a), an optical sensor 20 for detecting the reflected light of the light irradiated to the small bundle group M, and this optical sensor 20
(Not shown) for moving the optical sensor 20 at a position above the small bundle group M loaded in the loading unit 2.
.. are aligned with the directions of the band seals 21.21 .., respectively, that is, they are moved in the directions of arrows (a) and (b).

The optical sensor 20 is similar to the optical sensor 20 shown in FIG.
, The reflected light of the light applied to the band seals 21 is detected, and the detection signal is, for example, along the width direction of the small bundle as shown in FIG. When the binding tape 3 is detected, the binding tape 3 is flat and has a high level as indicated by reference numeral 22.
When 21 .. is not detected and when banding 21.21 .. (that is, banding 21.21 .. that faces in the vertical direction) located at the overlapping portion of the small bundle is detected,
Since the reflected light cannot be detected, the level becomes low as indicated by reference numeral 23. That is, the optical sensor 20 includes the band seal 2
.. Are scanned, a detection signal having a wide peak corresponding to the number of band seals 21.21 .. is output.

The detection signal of the optical sensor 20 is
The binding control unit 100 shown in FIG. 2 outputs the detection signal of the optical sensor 20 to a preset reference level (reference numeral 24 in FIG. 3B). Shown), the optical sensor 20
Is counted by counting the number of times the detection signal exceeds the reference level 24, the number of band seals 21
The number of m .. can be detected. A predetermined bundle value (ie, 10 bundles) indicating the number of small bundles to be bound into the small bundle group M is stored in advance in the binding control unit 100, and this value is output to the output of the optical sensor 20. Is determined by comparing with the number of small bundles m · m ·· obtained based on the binding tape 3 that binds the small bundles m · m ···.

The notification unit 10 outputs an error sound and an error display on condition that the unity control unit 100 determines that the small bundles m · m ··· in the small bundle group M do not match the predetermined number of bundles. Is what you do.

Hereinafter, the control contents of the binding control means 100 will be described step by step with reference to the flowchart of FIG. << Step 1 >> The operator arranges a small number of small bundles m · m ··· on the table 1 in a posture in which the longitudinal direction is horizontal, and then turns on the start button of the operation unit 11 by the operator.
When the start button ON of the operation unit 11 is turned on, the holding / rotating means 15 is driven, whereby the clamp plate 13 and the clamp plate 14 are moved in a direction approaching each other. Hold M.

<< Step 2 >> The optical sensor 20 is caused to travel across the small bundle group M held between the clamp plates 13 and 14, and based on the detection signal of the optical sensor 20 obtained at this time, the small bundle The number of small bundles m · m ·· in group M is counted. << Step 3 >> The small bundle MM counted in Step 2
Is determined to be equal to the predetermined number of bundles (10 bundles) set in advance, and in the case of YES, the small bundle group M is determined to be in the bundle number matching state, and the process proceeds to step 8. In the case of NO, it is determined that the small bundle group M is in the bundle number mismatch state, and the process proceeds to step 4.

<< Step 4 >> If it is determined in step 3 that the small bundle group M is in a bundle number mismatch state, the notifying means 1
0 is notified of the occurrence of an abnormality. << Step 5 >> The apparatus is temporarily stopped to input an instruction as to whether or not to bundle the small bundle groups M in the bundle number mismatch state. Note that such an instruction is input by the operator operating the operation unit 11. For example, pressing the start button of the operation unit 11 is an instruction to bind the small bundle groups M in a bundle number mismatch state. Pressing the stop button of the operation unit 11 is an instruction not to bind the small bundle groups M in the bundle number mismatch state. In step 5, when the stop button is pressed on the operation unit 11, the process proceeds to step 6, and when the start button is pressed on the operation unit 11, the process proceeds to step 7.

<< Step 6 >> The operation unit 11 in step 5
, On condition that the stop button is pressed.
By moving the clamp plates 13 and 14 in a state where they are sandwiched in a direction away from each other, the operator can recover the small bundle group M in the loaded state, and further, with respect to the small bundle group M in the loaded state. This flow is ended with the small bundle m being newly added. << Step 7 >> After the seal prohibition flag indicating that the small bundle group M is in the bundle number mismatch state is turned ON, the process proceeds to the next step 8.

<< Step 8 >> to << Step 9 >> The clamping / rotating means 15 is driven to rotate the table 1 to a position where the binding tape 3 can be clamped.
.14 while the tape 14 is temporarily opened.
Is driven to feed the binding tape 3 between the one clamp plate 13 or 14 and the small bundle group M to be pinched. Then, the clamping / rotating means 15 is driven again to rotate the clamp plates 13 and 14 holding the small bundle group M one or two times together with the table 1, whereby the one clamp plate 13 and the small bundle are rotated. The binding tape 3 sandwiched between the small bundles M is placed around the small bundles M (single or double).
Let it wind. Thereafter, the tape bonding and cutting means 6 is driven to thermocompression-bond the overlapping portion of the binding tape 3 wound around the small bundle group M and cut the portion after the thermocompression bonding, thereby cutting the small bundle group M along the longitudinal direction. The binding tape 3 is wound around the tape. After that, the small bundle group direction converting means 7 changes the direction of the small bundle group M on the table 1 from the posture in which the longitudinal direction is horizontal to the posture in which the short direction is horizontal. By repeating the winding operation of the tape 3, the bundling tape 3 is wound around the small bundle group M along the lateral direction, thereby forming a large bundle formed by bundling the small bundle group M of a predetermined number into a cross. create.

<Step 10> It is determined whether or not the seal prohibition flag is ON, and the seal prohibition flag is ON.
If the answer is YES, the process proceeds to step 11, and if the NO is not set, the process proceeds to step 12. << Step 11 >> The sealing prohibition flag that was turned on in step 7 is turned off, and the present flow ends. <Step 12> The stamping means 8 is driven to press the stamp indicating that there are 10 small bundles m, m,... On the binding tape 3 for binding the small bundle group M, and the flow is terminated.

As described in detail above, in the large sheet bundle binding machine according to the present embodiment, before the binding operation , the small bundles m · m · m · m · m ·
Count the number of steps (step 2) and, based on this count,
When it is confirmed that the number of small bundles is the normal number of bundles of 10 (YES in step 3), the binding operation is started, and the small bundle is attached to the binding tape 3 bundled in the small bundle group M with 1 small bundle.
Since the seal is pressed to ensure that there are no bundles (steps 8, 9, 10, and 12), the operator may notice a small bundle group M in which the number of small bundles is not 10 as in the related art. The binding tape 3 is prevented from being wound while the stamp is not pressed, and the stamp is pressed, thereby making it possible to reliably perform the binding operation. In addition, the bundle number counting means 9
In the state of being clamped by the clamping means 5
In order to count the number of bundles in the small bundle group M
The small bundle group M in the state can be counted. Accordingly
Thus, the number of bundles can be counted more accurately. Also,
In the above embodiment, when the number of small bundles is not the normal number of bundles of 10 (NO in step 3), only the bundle to the small bundle group M is performed based on the instruction of the operator (steps 8 and 9).・
10) Since the stamping is not performed (step 11), even if the small bundle group M is bound, by checking the presence or absence of the seal, the number of bundles having 10 small bundles matches. Can be distinguished from each other.

Next, another embodiment of the present invention will be described. The other embodiment described below differs from the previous embodiment in the configuration relating to the counting method of the bundle number counting means 9. That is, in the above embodiment, as shown in FIG. 1, the small bundle group M has the band seal 21 of the small bundle group M on one side of the loading unit 2, that is, on one side where the optical sensor 20 is arranged. However, as described later, when the small bundle group M is loaded into the loading unit 2 such that the positions of the band seals 21 are reversed by half each time, as described later, With only one optical sensor 20 as in the example, FIG.
A signal as shown in (b) cannot be obtained. Therefore, there are the following two methods for determining whether the small bundle group M loaded in the loading unit 2 has a predetermined number of bundles. The first method is a method of providing two optical sensors, and the second method is a method of estimating whether or not the number of bundles is a predetermined number by arithmetic processing while leaving one optical sensor. . Hereinafter, first, a method of providing two optical sensors will be described with reference to FIGS. 5 (a), 5 (b), and 5 (c). As shown in FIG. 5A, the optical sensors 30 and 31 according to the present embodiment move the upper position of the small bundle group M loaded in the loading unit 2 along the arrow (a)-(b) directions. Is movable,
One of the optical sensors 30 detects the number of small bundles half of the small bundle group M, and the other optical sensor 31 detects the small bundle group M.
Detect the number of small bundles in the other half. And in this case,
With respect to the loading unit 1A of the table 1, half of the small bundle group M (indicated by reference numeral 32) is a band 21 of the small bundle m, m,.
Are arranged along the movement path of the optical sensor 30, and the other half of the small bundle group M (indicated by reference numeral 33) is opposite to the half small bundle m · m ··. And a small bundle m, m.
Are arranged along the movement path of the optical sensor 31. Further, these optical sensors 30 and 31 are shown in FIG.
As shown in (c), the reflected light of the light applied to the band seals 21 is output to the binding control means 100 together as detection signals X1 and X2. In 100, it is determined whether or not the number of small bundles loaded in the table 1 is 10 based on the detection signals X1 and X2.

Hereinafter, with reference to FIGS. 5B and 5C, it is determined whether or not the number of small bundles loaded in the table 1 is 10 based on the detection signals X1 and X2 of the optical sensors 30 and 31. The determination method will be described. As shown by the detection signal X1, when the optical sensor 30 detects the wound portion of the band seal 21, 21,..., Five broad peak signals are obtained (indicated by t1), On the other hand, if an unwound portion of the band seal 21 is detected, the accumulated portion of the banknotes is read, so that an infinite number of narrow peak signals are obtained (indicated by t2). Similarly, the detection signal X
2, the optical sensor 31 is attached to the band 21.
When an unwound portion of 1... Is detected, an accumulated portion of banknotes is read, so that an infinite number of narrow peak signals are obtained (indicated by (t3)).
1,21 ... When a wound part is detected,
Five broad peak signals are obtained (indicated by t4).
Therefore, the number-of-bundles counting means 9 counts the number of wide peak signals from the detection signals X1 and X2 obtained from the optical sensors 30 and 31, respectively, and adds the two to add the two to the loading unit 2. The number of the small bundle groups M can be confirmed.

Next, a method for estimating whether or not the number of bundles is a predetermined number by arithmetic processing while keeping one optical sensor will be described. When only one optical sensor 30 (or 31) is provided, the obtained detection signal is as shown in FIG.
Either the detection signal X1 shown in FIG. 5B or the detection signal X2 shown in FIG. 5C. In this case, 5
Period (output time) t during which two wide peak signals were obtained
1 and a period (output time) t2 during which innumerable narrow peak signals are obtained, for example, these output times t1
T2 becomes almost the same, or "| t1-t2
| / T1 <0.1 ”(when the absolute value of the difference between t1 and t2 is less than half of one bundle), a period during which innumerable narrow peak signals in the small bundle group M are obtained ( The number of bundles during the output time t2 is determined to be the same five bundles as the period (output time) t1 during which five wide peak signals were obtained. Can be confirmed to be 10 bundles. Further, in the above-described method for estimating the small bundle group, the case where the bundles 21, 21,... Of the five bundles are reversed has been described. It can be easily understood that if the number of bundles is detected, the number of bundles can be inferred from the ratio with the remaining detection signals, and whether or not the total number is 10 bundles. Further, in the above-described embodiment, the case where each of the five bundles is continuous is shown. However, even when the bundles are loaded alternately, the above-described processing may be performed after adding the period. Would also be easily understandable.

In each of the above embodiments, an optical sensor is used as the number-of-bundles counting means 9. However, the present invention is not limited to this, and a contact-type sensor that contacts the binding tape 3 of the small bundle group M is provided. It is also possible to count the number of bundles from the vibration waveform. Further, in any of the above embodiments, the large bundle binding machine in which the bundling tape 3 is wound around the small bundle group M by rotating the small bundle group M has been described. However, the present invention is not limited thereto. PRIOR ART "
As described in the publication, the present invention may be applied to a large bundle binding machine in which the binding tape 3 is wound around the small bundle group M by moving the tip of the binding tape 3 around the small bundle group M. Further, in each of the above embodiments, the binding tape 3 is wound around the small bundle group M by rotating the table 1 provided in the loading unit 2 at the same position as the loading position of the small bundle group M. However, after the small bundle group M is loaded into the loading unit 2 as described in Japanese Patent Application Laid-Open No. Hei 4-201810 described in “Prior Art”, the loading unit 2 is moved to a binding position different from the loading position. The present invention may be applied to a large bundle binding machine in which the binding operation is started by moving.

Further, the rotation drive unit (not shown) of the table 1 provided in the loading unit 2, the tape supply unit 4, and the tape bonding / cutting unit 6 shown in any of the above-described embodiments are described in claims. A "binding unit" is configured. In each of the above embodiments, a large bundle having a small number of bundles of 10 (the predetermined number of bundles) is obtained. However, the present invention is not limited to this. The number of bundles can be arbitrarily set by an instruction from the operation unit 11. I do.

[0043]

As is apparent from the above description, according to the first aspect, before the bundling operation by the bundling means, the small bundle having a predetermined number of bundles set in advance based on the counting result of the bundling number counting means. It is checked whether or not the group is loaded, and when the loading of the small bundle group of the predetermined number of bundles is confirmed, the binding unit is caused to start the binding operation. It is possible to prevent the binding tape from being wound around the small bundle group in which the number of bundles does not match the predetermined number of bundles without confirmation, and it is possible to reliably perform the binding operation of the binding tape. Moreover, the bundle counting means is loaded in the loading section.
Small bundles in a state and clamped by clamping means
In order to count the number of bundles
Bundles can be counted. Therefore, counting the number of bundles
Can be performed more accurately.

According to the second aspect, when the binding operation by the binding means is completed, the marking means causes the binding tape bound to the small bundle group to be marked.
Since the seal is pressed on the binding tape, it can be confirmed that the small bundle of the small bundle group has a predetermined number of bundles.

According to the third invention, when it is confirmed by the bundle number counting means that the small bundle group having the predetermined number of bundles is not loaded, the notifying means notifies that the number of bundles does not match. Therefore, the operator can immediately confirm that the abnormality has occurred.

According to the fourth aspect, when the notification unit notifies that the number of bundles does not match, the operation unit further instructs the small bundle group in the number of bundles mismatching to be bound by the instruction signal. Is output, the binding control unit causes the binding unit to start the binding operation.
Even when the small bundle groups are in the bundle number mismatch state, it is possible to bind the small bundle groups.

According to the fifth invention, when the binding operation by the binding means is completed, the binding control means prohibits the marking means from marking the binding tape bound in the small bundle group. Therefore, no stamping is performed on the bundled bundles in the bundle number mismatch state, and it is possible to clearly distinguish them from the bundled bundles with a normal bundle number.

According to the sixth invention, the bundle number counting means is constituted by a sensor for scanning the banded portion of the small bundle loaded in the loading section. The delimited portion can be determined as the boundary of the small bundle, whereby the small bundle can be counted reliably.
