It is fixed to the mounting table 25 by vertically passing through both legs of a U-shaped rod holder 22 attached to the upper surface of the clamp arm table 14, which will be described later. The mounting base 25 and the table support 56 are coupled together with the slide rod and the table post 12d so as to be integrally rotatable.

A pair of rectangular link supports 14a are mounted on the upper surface of the clamp arm stand 14,
A pair of clamp arms 18 are rotatably attached via shaft supports 19 between the link supports 14a and at both ends thereof. A first roller 20 is attached to one end of each clamp arm 18 and joined to the lower surface of the engaging member 17, and a second roller 21 is attached to the other end of each clamp arm 18.

It is urged by the spring so as to come into contact with the inner surface of the clamping plate 24, and rotates in the direction of the arrow in conjunction with the clamping plate 24. For example, assuming that this receiving plate 26 does not exist, when the clamping plate 24 is opened to the solid line position as shown in FIG. There is a possibility that an accident may occur in which a sheet of paper falls from the notch 25a when it is torn, but the receiving plate 26 interlocking with the closing plate 24 has the function of preventing such an accident. Incidentally, reference numeral 58 is a bundle stopper plate for preventing over-insertion of paper sheets.

In FIGS. 2 and 4, a tape 28b from the tape reel 59 is located outside the left clamping plate 24.

The paper sheet rotation mechanism 30 consists of a pair of holding arms 31 that are rotatable with respect to each other, and a pair of mutually engaged gears 32 are coaxially connected to one end 31a of each holding arm 31. An arm member (not shown) provided on one of the holding arms 31 engages with a cam member (not shown) which is arranged and aligned with the drive shaft of the drive motor 31b' shown in FIG. When the holding arm 31 is operated via the cam member and arm member by the drive of the motor 31b', the other gear 32 that meshes with one gear 32 is also driven, and each holding arm 31 opens and closes in opposite directions. Driven. At the other end 31b of each holding arm 31, a bundle plate 33 is provided rotatably around a shaft 34 for holding a bundle of paper sheets 45 with a required pressing force and rotating it by a predetermined angle. A crank rod 36 is attached to one end of the crank portion 35 fixed to the gear, and the end portion 36a of the crank rod 36 constituting the rotational drive portion is coaxially connected to the one gear 32 via a link 37. The cam member 31b'' is engaged with a freely rotatable cam member 31b'', and this cam member 31b'' is further coupled to the drive motor 31b' via a rotation transmission member (not shown) such as a pulley or belt, and the crank rod 36 is rotated in its longitudinal direction. , the movement is converted into a movement in the rotational direction by the crank unit 35, and the bundle plate 33 is rotated by a predetermined angle (approximately 90 degrees in this embodiment). It is designed to similarly rotate the sandwiched bundle of paper sheets by 90 degrees.

Further, a heater cutter portion 38 is provided below the other holding arm 31. The heater cutter portion 38 includes a heater arm 39 that is rotatably provided above the base 1 and a rotatably provided heater arm 39 that is biased by a spring member 40 at the end of the heater arm 39. a heater 41, a heater arm driving roller 39a that is coaxial with the heater arm 39 and freely rotatable, and the heater arm 39.

Further, each component of the heater cutter portion 38 is integrally driven to rotate by a heater arm driving roller 39a and a drive motor (not shown).

Next, a case will be described in which the paper sheet strapping device according to the present invention is operated in the above configuration.
Now, for example, take 10 bundles of paper sheets (bills) 45, each bundle of 100 sheets wrapped with tape, and place them on the mounting table 25 shown in FIG. When the plate 26 is placed with one end in contact with the stopper plate 58 and the start button (not shown) is turned on, the second drive motor 1
2 is activated, and the cam 13 and the elevating lever 11 are driven in conjunction with each other, thereby pushing the second support shaft 8 downward. When the second support shaft 8 is pressed down, the engaging member 17 similarly moves downward, and the pair of clamp arms 18 located on the lower surface of the engaging member 17 are moved downwardly by the first roller. By being pushed down by
On one side of the clamping plate 24, the tape holding plate 29 and the tape holding plate 29 are slid toward the center of each other against the biasing force of a spring 23a wound around the holding shaft 23. The bundle of paper sheets 45 is lightly clamped by the operation of the clamp arm 18 and each clamping plate 24, and then the first drive motor 6 is operated and the bundle of paper sheets 45 is moved through the second gear 7 and the first gear 5. The first support shaft 3 rotates, and with this rotation, the clamp arm stand 14 fixed to the first support shaft 3 rotates, and the second support shaft 3 rotates as the first support shaft 3 rotates. 8 and the table post 12d etc. in which the connecting lever 12c is loosely fitted also rotate, and therefore the mounting table 25 etc. connected to the table support 56 and each slide rod 57 also rotate at the same time, and the mounting table 25 is rotated approximately clockwise. 90
It is controlled so that it stops in the state of rotation.

In the above-mentioned state, when the motor 53 next starts driving, its forward and reverse rotations are transmitted to each centering arm 51 via the belt 55.
1 is positioned between the pair of clamping plates 24 to press the bundle of paper sheets 45, and rotates inwardly to each other, so that the bundle of paper sheets 45 on the receiving plate 26 is 2 by the tip 51a of the centering arm 51
~The above-mentioned mounting table 25 is touched by tapping three times.
The bundle of paper sheets 4
Centering is performed by aligning both ends of 5. When this centering is completed, the motor 53 rotates in the reverse direction and each centering arm 51 returns to its original position (home position).
to return to. Thereafter, the tape guide 28a is rotated slightly by a drive motor (not shown), while the first drive motor 6 is rotated in the opposite direction, and the mounting table 25 is rotated counterclockwise. 29 and the tape path 2 formed between
When 9a coincides with the extension line of the tape guide 28a, the rotation of the mounting table 25 is stopped.

When the above-mentioned stopped state is reached, the tape feed roller 2
8 is rotated by a drive motor 28c, and the tape feed roller 28 and heater arm drive roller 39 are rotated by a drive motor 28c.
The tape 28b, which is held between
When the tip of b is lightly pressed by the second roller 21 of the clamp arm 18, the spring action of the tape holding plate 29 keeps the tip of the clamping plate 24 in a non-contact state with the back side of the clamping plate 24. Passing through the tape passage 29a between the tape holding plate 29,
When the required length of tape 28b is fed out, the tape feed roller 28 stops, and preparations for starting the tape hanging operation are completed.

When the preparation for applying the tape is completed, the second
The drive motor 12 operates again, and the cam 13 operates the lift lever 11, pushing the second support shaft 8 further downward than in the above-mentioned state, and interlockingly fixes it to the second support shaft 8. The engaging member 17 also descends, and each clamp arm 18 located on its lower surface
As the clamping plates 24 rotate toward the center, each clamping plate 24 also slides further toward the center, and on the one clamping plate 24 side, a large pressing force is applied to the tape holding plate 29 to overcome the spring action of the clamping plate 24. Since the tape is applied via two rollers 21, the tape holding plate 29 closes the tape passage 29a and attaches the tape 28b to the clamping plate 24 while holding the introduction part of the tape 28b.
The bundle of paper sheets 45, which is pushed toward the back side of the tape 28b and thus sandwiched between the clamping plates 24, is firmly clamped together with the tape 28b.

In the state where the paper sheet bundle 45 is pressed, the mounting table 25 is driven in the same manner as described above by the operation of the first drive motor 6, and the clock is rotated through the second support shaft 8, the table post 12d, etc. The tape 28b starts to rotate in the direction, and the tape 28b is wound around the bundle of paper sheets 45 together with the respective clamping plates 24, and the mounting table 2
5 rotates approximately two times to complete winding of the tape 28b, and then continues to rotate and reaches the tape bonding position.
The heater cutter part 3 is heated by a drive motor (not shown).
8 turns clockwise, and this heater cutter part 38
As the heater arm 39 and the tape guide 28a connected to the heater arm 39 via the connecting plate 44 rotate together, the heater 41 moves the tape 2 to the back side of one of the fastening plates 24.
Almost at the same time when the tape 8b is pressed into a temporarily bonded state, the cutter body 42 protrudes due to the suction drive of the solenoid 43 in the direction of the arrow, and the tape guide 28a
The tape 28b is brought into tension by the rotation of the tape 28b.
At the same time as this cutting operation is completed, the solenoid 43 is deactivated and the cutter body 4 is cut.
2 is controlled to move backward. On the other hand, heater 4
1 reaches the tape cut end while slidingly contacting the tape 28b due to the biasing force of the spring member 40, and when the tape cut end is thermally bonded, the heater cutter portion 38 returns to its original position. , the horizontal banding of the tape on the bundle of paper sheets 45 is completed.

Furthermore, even after the above-mentioned horizontal belt hanging work is completed,
The mounting table 25 continues to rotate until the surface of the bundle plate 33 of the paper sheet rotation mechanism 30 and the bundle direction of the paper sheet bundle 45 are parallel (that is, the original position). The rotation of the mounting table 25 is stopped by the operation of a detector (not shown). Next, the clamping state by each clamping plate 24 is such that the second drive motor 12 rotates in the opposite direction, so that the elevator lever 11 moves slightly upward, and the second support shaft 8 slightly returns to its original position. Control is performed to hold the bundle of paper sheets 45 in a weakly pinched state.

Next, when the third drive motor 12a is driven in the above-mentioned state where the bundle of paper sheets 45 is held, the table post 12d is raised via the cam 12b and the connecting lever 12c, and the table post 12d is moved up via the slide rod 57 to the mounting table. 25 rises higher than the upper end of each clamping plate 24. As a result, each clamping plate 24 that was weakly holding the bundle of paper sheets 45 placed in a horizontally oblong shape on the mounting table 25 before the lifting operation does not have a structure that allows the clamping plate 24 to move upward. For,
As the paper sheet bundle 45 rises higher than each clamping plate 24 together with the mounting table 25, the paper sheet bundle 45 acts to slip through between the paper sheet bundle 45 and the tape 28b, and in this state, the above-mentioned Second drive motor 12
By further rotating in the opposite direction, the second support shaft 8, which had been pushed down, completely returns to its original position.
Furthermore, with the return of the second support shaft 8, each clamping plate 24 is also released from the clamping by the second roller 21.
Due to the action of the spring 23a wound around the holding shaft 23, the holding shaft 23 is returned from the pressed position against the bundle of paper sheets 45 to the original released position.

When the drive motor 31b' is then driven in the state in which the mounting table 25 is raised, one of the holding arms 31 is operated in the closing direction as described above via the cam member and the engagement member (not shown), and the corresponding The other holding arm 31 also operates in the same manner through the other gear 32 that meshes with the gear 32 that is coaxial with the holding arm 31, and each holding arm 31 operates to close its arm, so that the One side of the paper sheet bundle 45 is held between a pair of bundle plates 33 .

When the bundle plate 33 reaches the pinching state, the third drive motor 12a is driven again, and the cam 12
The table post 12d starts to descend via the connection lever 12c and the table post 12d, and the mounting table 25 also begins to descend.
The drive motor 31 is coaxially connected to the gear 32 of the holding arm 31 in a state in which the drive motor 31 is directly driven.
The freely rotatable cam member to which the rotation of b' is transmitted drives the link 37 that engages with the cam member after a required time delay, and the crank rod is rotated using the end 36a of the connection point with the link 37 as a fulcrum. 36
When the rod is driven in its longitudinal direction, the amount of movement of this rod is converted into a rotational movement in the crank portion 35, and the amount of change causes the bundle plate 33 to rotate through 90 degrees via the shaft 34. In this case, one bundle plate 33 is forcibly rotated, and the other bundle plate 33
is in a state where it is free to rotate, so when the bundle plates 33 are rotated, the bundle of paper sheets 45 held by the pair of bundle plates 33 is simultaneously forced to remain in the clamped state. When the cam member (not shown) is rotated by the drive motor 31b', one rotation, that is, one cycle of operation of the cam member (not shown) by the drive motor 31b' is completed. , the drive motor 31b' stops.

That is, when the cam member 31b'' rotates once and returns to its original position, the other cam member on the gear 32 side, which is rotating synchronously via a rotation transmission member (not shown), also returns to its original starting position. As a result, the holding arm 31 opens its arms and releases the gripping state of the paper sheet bundle 45, so that the paper sheet bundle 45 changes its state from horizontally elongated to vertically elongated and is placed in the waiting state. It is placed on the mounting table 25 and held in a vertically strapped position.

Hereinafter, the tape hanging state will be similar to the above-mentioned horizontal band hanging, and a detailed description will be omitted here and will be briefly described. When the bundle of paper sheets 45 is placed on the mounting table 25, the bundle of paper sheets 45 is held upright by each clamping plate 24 as described above.
Once lightly clamped, the centering arm 51 performs a centering operation, and then each clamping plate 24 strongly clamps the sheet bundle 45, and tapes and tapes as described above. By continuing to perform operations such as gluing, vertical banding is completed. After this tape is hung vertically, the clamping pressure of each clamping plate 24 is slightly loosened as described above, and when the mounting table 25 rises again higher than the upper end of each clamping plate 24, the paper sheet Similar bundle 4
5 is released from the connection with each clamping plate 24, and the mounting table 25 is lowered and returned to its original position, thereby completing a series of banding operations, and paper sheets that have been horizontally and vertically hung. The bundle 45 can be taken out as is.

Furthermore, the configuration shown in FIGS. 5 and 6,
This shows another embodiment of the paper sheet rotation mechanism used in the present invention, and the same parts as the paper sheet rotation mechanism shown in FIG. 4 will not be described and will be given the same numbers.

A pulley 46 is provided on one shaft 34 of the bundle plate 33 in each holding arm 31 of the paper sheet rotation mechanism 30, and the belt 4 suspended on this pulley 46 is provided with a pulley 46.
The end of the holding arm 31 is suspended from a guide pulley 48 formed at one end of the holding arm 31 . By rotating an L-shaped lever 49 provided coaxially with this guide pulley 48, the bundle plate 3 is moved through the belt 47.
3 rotates 90 degrees, and the bundle of paper sheets 45 held by each bundle plate 33 can be rotated 90 degrees, and the belt 47, pulley 46, and L-shaped lever 49 rotate the bundle plate 33 rotation drive parts 36b are constituted.
