Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paper bundle banding device for bundling a paper bundle composed of a predetermined number of paper sheets with a band-wrapping tape.

[0002]

[Prior art]

 A banding tape is wrapped around to bundle paper sheets such as banknotes every predetermined number (for example, 100 sheets). To wind the banding tape around this predetermined number of paper sheets, A paper bundle banding device is used. As this paper bundle banding device, for example, a rotary ring is provided, the paper bundle is inserted inside the rotary ring, the tape interruption means is operated to feed out the band-sealing tape, and the paper bundle is clamped in the paper bundle. After the paper bundle is clamped by a member, the band-wrapping tape is chucked so that it can be sent out by the chuck member attached to the rotary ring, and the rotary ring is rotated to wind it around the paper bundle. , Known from the past.

Here, the band-wrapping tape to be wound around the paper bundle is fed out from a roll, and each time the band-wrapping tape is bound and bound to one paper bundle, it is cut into a desired length by using a cutter. . When the zipper tape is fed with the end portion of the band-sealing tape cut as described above, the cut end of the band-sealing tape is allowed to move freely. When the banding tape is misaligned, it becomes impossible to position it when it is thermocompression-bonded onto the already wound part, and the ends of the banding tape are diagonally overlapped and bonded and fixed. There is an inconvenience that it will end up.

Therefore, in order to prevent such a positional deviation from occurring in the feeding after the banding tape has been cut, various improvements have been conventionally made to the chuck member constituting the banding tape feeding device. ing. As such a conventional device, for example, it is constituted by combining a rotatably mounted chuck roller and a chuck block installed in a non-rotating state, and a guide wall is provided on both sides of the chuck roller. Is configured to guide both sides of the band-sealing tape.

[0005]

[Problems to be solved by the device]

 In this way, if the guide wall is provided, the band-sealing tape can be fed straight to some extent. However, in order to stabilize the feeding direction by the guide walls on both sides of the chuck roller, it is a condition that the leading edge of the band-sealing tape is straight inside the sheet bundle.

Here, as a mechanism for inserting the front end of the band-sealing tape into the paper bundle, a tape interrupting means is provided, and the tape is guided by the tape interrupting means so that the tape enters the paper bundle. The bundle of paper is divided into left and right, and after the banding tape is fed to a predetermined position, the tape interrupting means is detached from the bundle of paper. The tape interruption means has a split piece for interrupting the paper bundle, and the drive means causes the split piece to interrupt the paper bundle. Further, the split piece is formed with a slit having a predetermined depth on its side portion, and is set so that the band-sealing tape can be inserted into the slit. However, the slit of this split piece has a structure that guides only a part of one side in the feeding direction, not the entire tape.

From the above, when the end of the band-sealing tape is cut into the paper bundle, the portion of the tape not guided by the tape interrupting means is inserted while sliding directly on the paper bundle. Therefore, in the direction perpendicular to the tape feeding direction, there is a difference in resistance when the tape is inserted. Further, the tape interruption means is designed so that the split piece swings from the viewpoints of simplification of its structure and saving of operation space. As a result, the leading end portion of the band-sealing tape may be bent. Therefore, even if the chuck roller is provided with a guide wall, it is not possible to correct the posture of the banding tape by this guide wall. Even when the split pieces slide, the resistance between the strip sealing tape and the slits of the split pieces may be increased when the split pieces are pulled out of the paper bundle after inserting the strip sealing tape for a predetermined length into the paper bundle. However, there is a possibility that the band-sealing tape inserted in the bundle of paper may be displaced.

The present invention has been made in view of the above points, and an object of the present invention is to make it possible to wind a band-sealing tape around a paper bundle without causing positional displacement. To provide a device.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides the chuck roller with a tape guide wall which guides both sides of the band-sealing tape, and the position of the chuck roller in the chuck block is larger than that of the tape. The feature is that a guide member for guiding both sides of the banding tape is provided at the front position in the feeding direction.

[0010]

[Action]

 The present invention is constructed in this way. First, in a state in which the chuck roller and the chuck block are separated from each other, the band-sealing tape is held by the tape interrupting means and interrupted in the paper bundle. At this time, since both sides of the band-sealing tape are guided by the tape guide wall of the chuck roller and the guide member of the chuck block at two different positions in the feeding direction, the band-sealing tape is always straight. There is no danger of moving to the left and right. Further, even when the rotary ring is operated to wind the band-wrapping tape around the bundle of paper, the band-wrapping tape is fed while being guided at the two positions, so that the tape is surely fed straight. As a result, even if the banding tape is wound around the bundle of paper in a plurality of turns, the tapes of the respective layers are completely overlapped.

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, FIG. 2 shows an example of a paper bundle banding device. In the figure, reference numeral 1 denotes a paper bundle in which a predetermined number of paper sheets are arranged, and 2 denotes a band-sealing tape for bundling the paper stack 1, respectively. The band-sealing tape 2 is wound around the paper bundle 1 by about double winding. The end portion of the band-wrapping tape 2 is adhered and fixed by superposing the end portion on the portion already wound around the paper bundle 1 and thermocompression bonding. An adhesive such as a hot melt adhesive is applied on one side. Then, the paper bundle 1 is clamped by the clamp member 3 including the support 3a and the clamp plate 3b with the banding tape 2 sandwiched therein, and is bound by the banding tape 2. There is. A tape feed roller 4 and a guide roller 5 are provided to feed the band-sealing tape 2 into the paper bundle 1.

Next, reference numeral 6 denotes a rotary ring having a space into which the sheet bundle 1 is inserted, and the rotary ring 6 is rotatably supported by support rollers 7 provided at three positions. The rotary ring 6 is provided with a chuck mechanism 8 for chucking the band-sealing tape 2. The chuck mechanism 8 holds and guides the band-wrapping tape 2 when the rotary ring 6 rotates in order to band-bond the sheet bundle 1 with the band-wrapping tape 2. Further, a tape interrupting means 9 is provided in order to cut the leading end of the band-sealing tape 2 into the sheet bundle 1. Further, 10 is a cutter which is located between the tape feed roller 4 and the guide roller 5 to cut the band-sealing tape 2, and 11 is a cutter for winding the band-wrapping tape 2 around the paper bundle 1 by a predetermined amount. A tape pressing member that is pressed against the side of the bundle 1 of paper to press the end of the band-sealing tape 2 so as not to loosen, and 12 is an end of the band-sealing tape 2 that is superposed on the already-wound part and is heated. A heat-sealing member for sealing is shown, and these tape pressing member 11 and heat-sealing member 12 can be displaced by a cam mechanism 13 between its operating position and a non-operating position separated from the rotary ring 6. ing. Reference numeral 14 is a solenoid for driving the cutter 10.

Here, the chuck mechanism 8 for sandwiching the band-sealing tape 2 and winding it around the bundle of paper has a structure shown in FIG. As is clear from the figure, the chuck mechanism 8 comprises a chuck roller 80 and a chuck block 81. The chuck roller 80 is rotatably attached to a rotary shaft 82 provided upright on the rotary ring 6, and the chuck roller 80 has a bulged portion 80a having a large diameter at its central portion, and then the chuck roller 80 extends toward both ends thereof. It is formed so as to be reduced in diameter, and flange portions 80b, 80b constituting tape guide walls are formed at both ends thereof. On the other hand, the chuck block 81 is mounted in the circular arc groove 6a formed in the rotary ring 6, and the chuck block 81 cannot rotate but can move along the circular arc groove 6a. ing . Further, the chuck block 81 is normally urged by a spring 83 in a direction of contacting the chuck roller 80, and by rotating a lever 84 to push a pin 85 implanted in the chuck block 81, The chuck block 81 can be separated from the chuck roller 80. The portion of the chuck block 81 that faces the chuck roller 80 is a concave curved surface 81a that curves in the rotation direction of the chuck roller 80, and the support block 86 is connected to the upper position of the chuck block 81. The support block 86 is provided with a pair of guide rods 87, 87 as guide members for guiding the both sides of the band-sealing tape 2 upright.

Further, the tape interrupting means 9 has a split piece 90, and the split piece 90 is formed with a guide groove 90a for guiding the banding tape 2 having a predetermined depth on its side portion. There is. Then, the split piece 90 is cut into the sheet bundle 1 by a swing mechanism (not shown) at a standby position between the chuck mechanism 8 and the sheet bundle 1 in the rotary ring 6, as shown by a solid line in FIG. It can be displaced between the interrupt position and the retracted position separated from the rotary ring 6.

The present embodiment is configured in this way, and its operation will be described below. First, the chuck block 81 is moved along the circular arc groove 6a against the spring 83, and at the same time, the split piece 90 is placed at the standby position. Therefore, the band-sealing tape 2 is fed out through the tape feed roller 4, and the tip end of the band-sealing tape 2 is inserted between the chuck roller 80 and the chuck block 81 into the guide groove 90a of the split piece 90. In this state, while continuing to feed the banding tape 2, the split piece 90 is moved toward the sheet bundle 1 to be cut into the sheet bundle 1, and then the split piece 90 is displaced to the retracted position. Let me

In this state, the sheet bundle 1 is inserted into the rotary ring 6, and the leading end portion of the band-sealing tape 2 is inserted into the sheet bundle 1. After that, the chuck block 81 is brought close to the chuck roller 80, and the band-sealing tape 2 is sandwiched between them, and the rotary ring 6 is rotated to rotate the band-sealing tape 2 sandwiched by the chuck member 8 into a paper bundle. Wrap around 1. Then, when the banding tape 2 is fed by a predetermined amount, it is cut by the cutter 10, and the cut free end is superposed on the already wound portion and is pressed by the tape pressing member 10. At the same time, by operating the heat seal member 11, the end portion of the band-sealing tape 2 is adhered and fixed.

Here, the banding tape 2 is wound around the paper bundle 1 for two or more rounds, and at this time, it is necessary to prevent the positional deviation from occurring between the first round and the second round. I have to. Therefore, when the band-seal tape 2 is cut into the sheet bundle 1 by the split pieces 90 constituting the tape interrupting means 9, both sides of the band-seal tape 2 are guided by the flange portions 80b and 80b of the chuck roller 80. At the same time, it is guided by the guide rods 87, 87 which are continuously provided on the chuck block 81 and are provided on the support block 86 located on the front side of the chuck roller 80. Therefore, since the band-sealing tape 2 is guided at two positions before and after the moving direction, even if the band-sealing tape 2 is only partially inserted in the guide groove 90a of the split piece 90, that position is not increased. There is no risk of misalignment. Further, even when the banding tape 2 is wound around the sheet bundle 1 while rotating the rotary ring 6, the banding tape 2 is guided at the two positions as described above, and therefore the banding tape 2 is also guided at this time. There is no displacement.
