The present invention relates to a mounting device.

[Prior Art] A bundling tape is used for bundling a predetermined number of paper sheets such as banknotes, and in order to wind the bundling tape around the bunch,
A paper bundle banding device is used.

In this paper bundle banding device, the band feeding tape is fed out by a tape feeding mechanism, one end of the band banding tape is sandwiched in the paper bundle, and the banding tape is wound around the paper bundle by a paper banding tape winding device. The other end is superposed on the already wound portion and fixed by means such as thermocompression bonding. As a device for winding the paper bundle band-sealing tape, a rotary ring having a chuck member for sandwiching the band-sealing tape so that the band-wrapping tape can be sent out is provided, and the paper bundle is placed in a state of being surrounded by the rotary ring. By rotating the rotary ring,
Conventionally, a band-wrapping tape guided by a chuck member is wound around the bundle of papers.

Here, the chuck member provided on the rotary ring is
In order to smoothly guide the band-sealing tape, a chuck roller that abuts on the band-sealing tape and rotates according to the feeding of the band-sealing tape, and a tape that is opposed to the chuck roller and holds the band-sealing tape so as not to be displaced. It consists of a chuck block for holding down. The band-sealing tape is cut into a predetermined length during the band-sealing work. Therefore, after the end portion of the band-sealing tape has passed through the chuck member, the band-sealing work is not performed. Before starting, it is necessary to insert the band-sealing tape between the chuck roller and the chuck block. Therefore, in order to enable the insertion of the band-sealing tape, one of a pair of chuck members consisting of a chuck roller and a chuck block is provided as a movable side chuck part that can be brought into contact with and separated from the other. Between the chuck position for sandwiching the band-sealing tape by joining the chuck part to the fixed-side chuck part and the tape insertion position where the band-sealing tape can be inserted by separating from the fixed-side chuck part. It is configured so that it can be displaced.

Thus, in the paper bundle banding tape winding device according to the prior art, in order to displace the above-mentioned movable side chuck part between the chuck position and the tape insertion position, the rotary ring is attached to the rotary ring. An auxiliary ring that can rotate integrally and that can rotate relative to it by a predetermined angle is provided, and the movable chuck part is attached to the auxiliary ring, and the auxiliary ring is attached to the rotary ring. The movable-side chuck part piece is configured to be displaced between the chuck position and the tape insertion position by relative rotation.

[Problems to be Solved by the Invention] In the above-described device for winding the band-wrapping tape of the prior art, an auxiliary ring separate from the rotary ring is provided, and the auxiliary ring has a movable chuck part. Since the structure is mounted, there is a disadvantage that the structure of the device becomes complicated and the size becomes large, and in addition, it becomes heavy and the load of the motor for driving the rotary ring becomes large.

The present invention has been made in view of the above points, and an object of the present invention is to provide a winding device for a paper bundle bandage tape which has a simple structure and is small and compact.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the paper bundle banding tape winding device according to the present invention includes a pair of chuck parts that sandwich the banding tape so that the rotary ring can feed the banding tape. Of the chuck members, one of the chuck members is a fixed-side chuck member that is fixedly installed on the rotary ring, and the other chuck member is on the rotary ring and is concentric with it. The movable chuck part is formed by being attached to a slider slidable along a guide groove formed in an arc shape, and one of the movable chuck part and the fixed chuck part is formed by a roller. And the other is formed by a concave arc surface that engages with the roller,
A chuck position for sandwiching the band-sealing tape by joining the two, and a chucking part that is separated from the fixed-side chuck part piece, and is movably installed between the tape insertion position where the band-sealing tape can be inserted therebetween. The movable side chuck part piece is urged by the urging means to the chuck position, and the movable side chuck part piece is provided with an actuating member which engages with an actuating lever so as to resist the urging means. The rotary ring is provided with a stopper capable of coming into contact with an operating lever engaging with the operating member, and the rotary lever is brought into contact with the operating lever to bring the rotary lever into contact with the operating lever. The feature is that the ring is positioned.

[Operation] In order to wind the band-wrapping tape around the paper bundle using the above-described device for winding the band-wrapping band-wrapping tape, the movable-side chuck part provided on the rotary ring is separated from the fixed-side chuck part at the tape insertion position. In, the banding tape is inserted between them, and the bundle of paper is inserted into the rotary ring, so that the bundle of paper is surrounded by the rotary ring. After that, one end of the band-sealing tape is sandwiched in the paper bundle, and the movable-side chuck part is displaced to the chuck position so that the band-sealing tape is sandwiched between both chuck parts and the rotary ring is rotated. As a result, the band-sealing tape is wrapped around the bundle of paper. Then, the band-sealing tape is cut into a length sufficient to wind, for example, about 1.75 times around the paper bundle, and after its end passes through this chuck member, it is overlapped with the portion already wound around the paper bundle. By fixing the end portion by means of thermocompression bonding or the like, band binding is performed on the sheet bundle. After the banding is completed, the movable lever chuck piece is displaced to the tape mounting position separated from the fixed chuck piece by operating the operating lever to engage the engaging member. As a result, it becomes possible to smoothly and surely insert the band-sealing tape between the chuck pieces.

When the rotary ring rotates, it is necessary to regulate the band-sealing tape by the chuck member over as long a range as possible in order to accurately feed the band-sealing tape without displacement. Therefore, by forming the chuck piece on the other side with respect to this roller with a concave arc surface, the banding tape is wrapped around the roller, and is clamped between the arc surface and the rolling portion. The band-sealing tape can be sent straight.
Further, since the movable chuck part is attached to the rotary ring and to the slider slidable along the guide groove formed in an arc shape concentric with the rotary ring, both chuck parts can be moved by displacing the slider. The entire contact area of the pieces abuts with a uniform force, so that the feeding of the band-sealing tape becomes more accurate and smooth.

After the completion of the above-mentioned operation is detected by the encoder 37, when the ring drive motor 21 is operated to rotate the rotary ring 7, the band-sealing tape 2 chucked by the chuck member 9
Is sent out while being guided by the chuck member 9. Here, the chuck block 11 constituting the chuck member 9 is composed of a concave arc surface, and the chuck block 11 abuts the chuck roller 10 over a considerable angle, so that the band-tapping tape 2 is chucked by the chuck block 11.
And the chuck roller 10 are guided so as to be sandwiched between them and the chuck block 11 moves along the guide groove 15 which is concentric with the rotary ring 7. Since such a force is applied, the banding tape 2 is fed in a straight-ahead state by the rotation of the rotary ring 7 and is wound around the sheet bundle 1 extremely accurately without causing a positional deviation or the like. When the band-wrapping tape 2 reaches the specified length, the cutter
33 is activated and its end is cut off. Then, when the rotary ring 7 rotates, for example, 1.75, the rotation angle is detected by the tooth number detector 35, the actuation motor 30 is actuated again based on this detection signal, and the tape pressing member 17 causes the band-tapping tape 2 to operate. The end of the tape is pressed down to prevent it from loosening, and while the tape pressing member 24 presses the band-sealing tape 2, the heater 25 operates and the end of the band-sealing tape 2 is thermocompressed, After the banding of the paper bundle 1 is completed, the clamp piece 3b is separated from the clamp piece 3a, and the paper bundle 1 can be taken out.

At this time, not only the above-mentioned bearing 18 but also the operating lever 19
The rotary ring 7 also engages with the stopper 20 attached to the rotary ring 7, so that the rotary ring 7 is
It stops at the position of engagement with 19, and excessive rotation due to its inertial force is prevented.

Then, when the removal of the bundle of paper 1 is completed, the bundle of paper separating members 6
Is returned to the operating position, the banding tape 2 is inserted into the sheet bundle splitting member 6 through the gap between the chuck block 9a and the chuck roller 9a, and the standby state for banding the next sheet bundle is obtained. Therefore, it is possible to continuously perform the banding operation for the bundle of papers by repeating the above-described operation.

In addition, in the above-described embodiment, among the pair of chuck part pieces constituting the chuck member, the fixed chuck part piece is formed by the chuck roller, and the movable chuck part piece is formed by the chuck block. In short, if the band-sealing tape can be pinched so that it can be sent out, the movable side can be formed by a chuck roller and the fixed side can be formed by a chuck block, or both can be formed by a chuck roller. Alternatively, it may be formed by a chuck block. Further, the slit groove for guiding the slider is not limited to the arc-shaped slit groove, and may be a linear groove.

[Effects of the Invention] As described in detail above, the winding device for a band-wrapping tape according to the present invention has a structure in which the chuck member is directly provided on the rotary ring, so that the structure of the band-wrapping tape winding mechanism can be simplified. When the rotary ring rotates and the banding tape is wound around the paper bundle, the banding tape is guided by the chuck member, and one of the chuck pieces constituting the chuck member is formed by a roller, The other is formed with a concave arc surface that contacts this roller,
As the banding tape is wrapped around the roller, it is guided so as to be held by the arcuate surface, and the movable chuck part is guided by the guide ring concentric with the rotary ring. Since the entire abutting portion of the sheet abuts with a uniform force, it is possible to guide the band-sealing tape so as to advance straight, and to wind the sheet bundle around the sheet bundle accurately without misalignment. In addition, since a stopper is provided that can contact an operating lever that is engaged with an operating member that is provided for chucking or releasing the banding tape, this stopper is brought into contact with the operating lever. As a result, various effects can be obtained in which the rotary ring can be positioned so as not to rotate excessively.
