Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a large bundle bundling device that bundles a plurality of bundles of paper sheets, which are bundled by a predetermined number, into a large bundle.

[0002]

[Prior art]

 For example, in the case of banknotes, a required number of banknotes (for example, 10) are bundled into a large bundle by bundling every 100 sheets. In order to bind such a large bundle, it is necessary to bind the bills at two points in the short side direction and the long side direction with tape.

As a large-bundle binding machine for mechanically performing such a large-bundle binding, the one described in Japanese Patent Application Laid-Open No. 2-82020 is known. The large-bundle binding machine described in this publication sets up a number of paper sheets to be bundled on a rotary table so that the longitudinal edge of the bundle is placed on the table, holds both ends of the tape, and then holds the tape. Wrap the paper in the long direction of the paper to fasten it, then lift the paper and put it up so that the edge of the paper in the short direction is placed on the table, and hold both ends of the paper. A large bundle is formed by winding the tape in the lateral direction of the paper sheets and fixing them.

However, in the above-mentioned conventional structure, since the bundle of paper sheets is set in a state of standing on the table and is bound, the bundle of paper sheets is held between the vertical position and the horizontal position, and the paper sheet bundle group is respectively held. Since a large bundle is bound by rotating the bull, it is not easy to change the posture, and the workability is poor due to the alignment of the large bundle binding position. There is a problem that the device becomes large and complicated because it is bound.

Therefore, if the bundle of paper sheets is set in a stacked state, the bundle of paper sheets is rotated, and a large bundle binding tape is wrapped around the bundle to bundle the paper sheets. Alignment of bundle groups is easy and there is an advantage that the machine itself can be made compact.

[0006]

[Problems to be solved by the device]

 However, as described above, when the bundle of paper sheets is set in a stack and rotated by the holder plate to hold it in a sandwiched state, the end of the large bundle binding tape is also held by the holder plate at the same time. If the end is not in the specified position, the holder plate will not be able to hold it securely.If this fails, the tape end will come off and will not be bound, or the held tape end will bend and a defective bundling product It causes various problems such as generation. Also, in the case of large bundle binding, the winding length of the tape becomes long, which makes it difficult to bind tightly, and this often causes defective binding.

In view of this, the present invention has been made for the purpose of providing a large bundle binding device for paper sheets capable of securely holding the leading end of the tape even if a large bundle is bound, and tightly binding the large bundle. Is.

[0008]

[Means for Solving the Problems]

 An object of the present invention is to solve the above-mentioned problems of the conventional technique. A pair of supported holder plates, a plate opening / closing mechanism that opens and closes the pair of holder plates by rotation of another rotating shaft, and a lower surface side of the plate in the vicinity of a side located above the holder plate. The tape supply mechanism includes a tape feeding mechanism for locating the tape end at the upper end, and a cutter and trowel mechanism arranged near the upper holder plate and moving between a retracted position and an operating position after advancing. The mechanism clamps the tape end fed from this supply mechanism between the holder plate and the bundle of paper sheets, and feeds the tape at the same time when the rotation starts, and the tape is fed into the paper sheets. It has a feed roller to stop the tape feeding when at least one corner of the group has been applied to give tension to the tape, and to reversely drive the tape supply mechanism at the end of winding a predetermined number of windings of the tape to tighten it. It is characterized by

[0009]

[Action]

 Set the stack of paper sheets on the holder plate located at the bottom and set the short side as the front-back direction. At this time, the tape end is located along the lower surface of the upper holder plate, and when the stack of paper sheets is sandwiched between the upper and lower holder plates by the operation of the plate opening / closing mechanism, the tape end is also held. Be held. Then, by rotating the rotating plate, the holder plate rotates while holding the bundle of paper sheets, and when the tape goes around one corner of the bundle of paper sheets, the tape supply mechanism stops and tension is applied to the tape. A given bundle of paper sheets is rotated and wound around it, and when it is wound a predetermined number of times, the tape supply mechanism is driven in reverse to pull the tape and tighten it. Then, the trowel advances and heat-bonds the tape, and the cutter cuts it, ending the binding of the bundle of paper sheets in the longitudinal direction.

When this bundling is completed, the upper and lower holder plates are separated from each other, and the paper sheet bundle group is unpinched so that it can be pulled out. After that, the paper sheet bundle group is pulled out at that position. Turn it again and set it again with the longitudinal direction in the front-back direction.During this time, the tape end is placed along the lower surface of the upper holder plate in the same way as described above, and the tape in the lateral direction is aligned in the same manner as in the case of binding in the longitudinal direction. Bundling is performed, whereby the bundle of paper sheets is bound in a cross shape, and the large bundle is completed.

Further, there is a motor 30 for stopping and positioning the rotary plate 8, and a belt 33 is wound around a pulley 31 on the shaft of the motor 30 and a pulley 32 coaxial with the pulley 24.

A detection plate 34 is fixed on the same axis as the pulley 24, and a fixed position detection sensor 35 detects a detection portion 34 a such as a notch of the detection plate 34 to detect the first rotary shaft 2. The stop position is decided.

A detection plate 36 is fixed coaxially with the pulley 28 of the motor 27, and a sensor 37 for detecting the degree of tightening by the holder plates 14 and 14 is attached to the detection plate 36. Further, a detection plate 40 is fixed coaxially with a gear 39 that meshes with the gear 38 of the first rotation shaft 2, and a rotation angle detection sensor 41 of the rotation plate 8 is attached to the detection plate 40.

In FIG. 2, reference numeral 42 is a sensor for detecting the fixed position stop of the rotary plate 8.

The tape feeding mechanism 43 has a tape guide tunnel 45 of a tape T drawn out from a tape reel 44 (FIG. 9 (A)), and an outlet end 45 a at the end of the tape guide 45 is It is arranged on the lower surface of the upper holder plate 14 in the open position, facing the same direction, and in the middle of this tape guide 45, rollers 46, 46 for holding and feeding the tape T are provided.

One of the rollers 46, 46 is driven to rotate forward and backward by a motor (not shown), and the end of the tape T is held between the holder plate 14 and the upper surface of the sheet bundle group P. The tape T is fed out at the same time when the tape T starts to rotate, and when the tape T goes around one corner of the bundle of paper sheets, it is stopped and tension is applied to the tape T. It is designed to be tightened.

A guide block 50 is provided at a position facing the end of the tape guide 45, the upper end of which is swingably supported on the machine 1 side by a shaft 51. The lower part of the guide block 50 is shown in FIG. As shown in FIG. 7, a V-shaped groove 47 having a shallow cross section perpendicular to the feeding direction of the tape T is formed, and a pressing roller 48 is freely rotatable by a shaft 49 at a position corresponding to the deepest part of the groove 47. The rib Ta is formed in the feeding direction of the tape T to be fed.

A cam follower 54 is pivotally mounted on one corner of the upper end of the guide block 50. The cam follower 54 is constantly abutted against the cam surface of a cam 55 pivotally supported on the machine body 1 side by a spring 56. Has been done. The cam 55 has a height 55a in a part of the cam surface, and is arranged to feed out the tape T when the cam follower 54 is located at the height 55a. The rotation of the cam 55 causes the cam follower 54 to move to the height 55a. The guide block 50 is rotated upward by the action of the spring 56 when the tape falls off the lower part 55b from above, and the tape is flipped upward.

The trowel mechanism 57 has a trowel 59 to which a cutter 58 is attached, and the trowel 59 is attached to a support body 61 which is vertically moved along a guide 60 provided in the machine 1 in a vertical direction. It is supported so as to be more swingable, and is urged by a spring 63 so as to always maintain a drooping posture.

A spring (not shown) provides the supporting body 61 with a habit of ascending and returning, and a roller 66 at the tip of an arm 65 pivotally supported by the shaft 64 on the machine body 1 abuts on the upper surface of the supporting body 61. The cam follower 67 at the rear end of the arm 65 is in contact with the cam surface of the cam 68 axially attached to the machine body 1, and the rotation of the cam 68 by the motor 69 causes the arm 65 to swing vertically. Then, the swinging pushes down the support body 61 against the spring bias. In FIG. 9, P indicates a bundle of paper sheets.

Next, the operation of the above embodiment will be described with reference to the operation diagrams shown in FIGS. 9 (A), (B) to 12 (A), (B).

Before the start, as shown in FIG. 9 (A), the pair of holder plates 14 and 14 are vertically positioned and stopped, and the tip of the tape T is held by the pressing roll 48 and V of the guide block 50. A rib Ta having a V-shaped cross section is formed by the groove 47 having a cross section, and the rib Ta is placed in such a manner as to enter the lower surface of the upper holder plate 14. The trowel mechanism 57 is in a position retracted upward.

Here, from the front side of the machine body 1, the paper sheet bundle group P is placed on the lower holder plate 14 with its lateral direction being the front-back direction, and pushed forward as far as the paper sheet bundle group P. The two lateral ends stop by contacting the outer surfaces of the left and right rods 20, 20 of the rotary frame 19, and the insertion position in the lateral direction is regulated to set a predetermined binding position.

When the machine is started in this way, first, the motor 27 is started to rotate the second rotating shaft 4, and the screw shaft 11 is rotated through the bevel gear 12 that meshes with the bevel gear 13 at the tip of the second rotating shaft 4. The upper and lower holder plates 14, 14 move toward each other so that the holder plates 14, 14 contact the upper and lower surfaces of the sheet bundle group P. At this time, the tip of the tape T is also sandwiched between the upper holder plate 14 and the upper surface of the sheet bundle group P (FIG. 9 (B)).

Further, when the bundle of paper sheets P is tightened by the rotation of the second rotary shaft 4 and the movement amount of the holder plate 14 becomes small, the rotation speed of the motor 27 also becomes slow, and the sensor 37 moves on the shaft of the motor 27. The interval at which the slits of the detection plate 36 are detected becomes longer, and the motor 27 is stopped when the slits are not detected for a predetermined time or longer.

Next, the motor 23 is activated to rotate the first rotary shaft 2, and the rotary plate 8 rotates together with the holder plates 14 and 14 in the direction in which the tape T is wound around itself (arrow direction in FIG. 9B). The tape T is rotated and wound along with the rotation. At this time, the feed rollers 46, 46 rotate forward to positively feed the tape T, relieve the tension of the tape T between the feed rollers 46, 46 and the sheet bundle group P, and the tip of the tape T is held by the holder. The bottom surface of the plate 14 is prevented from coming off (FIG. 10A).

After the tape T has passed around at least one corner of the paper sheet bundle group P (FIG. 10 (B)), the feed rollers 46 and 46 are braked, and the tape T is wound under tension. Continuation is continued. The rotation control of the feed rollers 46, 46 is performed by detecting the rotation angle of the rotary plate 8 by the sensor 41.

In this way, when the tape T is wound around the longitudinal direction of the bundle of paper sheets P two times, the sensor 42 detects the fixed position and the motor 23 of the first rotating shaft 2 is stopped, while the feeding is performed. A reverse rotation command is given to the rollers 46, 46, and the tape T is pulled back and tightened (FIG. 11A).

Next, the motor 69 rotates, the cam 68 rotates, the arm 65 swings, the support 61 of the iron mechanism 57 is pushed down along the guide 60, and the lower end of the iron 59 is in the middle of the movement. The tape T is brought into contact with the tape T, and the tape T is pressed against the upper surface of the upper holder plate 14 to be heat-bonded (FIG. 11B).

After that, the cam 55 rotates in the direction of the arrow in the drawing, and the cam follower 54 of the guide block 50 falls from the high place 55 a of the cam 55 to the low place 55 b, so that the guide block 50 moves the shaft 51 by the force of the spring 56. The tape T is suddenly turned clockwise in the drawing in the center of the drawing, and the tape T is pulled upward in the initial stage of the turning, so that the tape T is cut by the cutter 58 attached to the iron 59 and the guide block 50 is raised as it is. (FIG. 12A).

Then, by the action of the cam 68, the trowel 59 continues to descend through the arm 65, and the cut tape T end is pressed and rubbed to proceed, and the thermal adhesion of the tape T end is completed and the feed roller 46 is moved. , 46 reversely rotate to pull back the tape T, and stop at a position where its tip slightly projects from the outlet end 45a of the tape guide 45 (FIG. 12 (B)).

After that, the cam follower 54 of the guide block 50 rides on the high place 55a of the cam 55 by the rotation of the cam 55, the guide block 50 is returned to the initial posture, and the arm 65 is raised and returned by the rotation of the cam 68. The support body 61 is returned to the initial state by returning to its original position by the spring bias.

Further, the motor 27 reversely rotates, the second rotary shaft 4 reversely rotates, and the screw shaft 11 reversely rotates, whereby the driven bases 14b and 14b leave the bases 14a and 14a in place. Return to the initial state.

After this, when the paper sheet bundle group P is pulled out toward the front and pulled out together with the tape T from between the holder plates 14 and 14, the space between the holder plates 14 and 14 is caused by the action of the compression springs 16 and 16 (FIG. 9A). Then, the feed rollers 46 and 46 are rotated in the forward direction so that the tape T end is placed along the lower surface of the upper holder plate 14.

Next, the paper sheet bundle group P is rotated by 90 °, and the paper sheet bundle group P is placed on the lower holder plate 14 with the longitudinal direction of the paper sheet bundle group P facing forward and backward, and is inserted forward. At this time, if both sides of the bundle of paper sheets P in the longitudinal direction are inserted between the rods 20 and 20 so as to be aligned with the inner surfaces of the rods 20 and 20 of the rotary frame body 19, the rods 20 and 20 regulate the width direction. Then, it is set at the correct position, and the insertion depth is stopped by the tip of the sheet bundle group P hitting the rotary plate 8. As a result, the bundling position is determined, and the bundling in the lateral direction is performed by the same action as the bundling in the longitudinal direction.

As a result, the large bundle cross binding of the paper sheet bundle group P is completed.

[Effect of device]

 As described above, according to the present invention, the tape end is held between the paper sheet bundle group and the holder plate, and the tape feeding mechanism is driven at the same time when the paper sheet bundle group starts to rotate. Since the tape is fed out, the end of the tape does not come off and binding failure is not caused, and the tape is fed from the tape feeding mechanism when the tape goes around at least one corner of the bundle of paper sheets. Is stopped and tension is applied to the tape, and when the tape is wound a predetermined number of times around the bundle of paper sheets, the tape feeding mechanism is reversely driven to tighten the tape. As a result of binding, it is possible to obtain a bound state that does not loosen later.
