Description

[Detailed Description of the Invention] [Industrial Application Field] This invention forms a large bundle by winding tape in a criss-cross pattern around a required number of bundles of paper sheets that have been bundled in advance into small bundles. This invention relates to a large bundle binding machine for paper sheets.

[Conventional technology]

Conventionally, various devices have been known for lifting this type of paper sheet, but for example, the device described in Japanese Patent Application Laid-Open No. 60-158020 [(first known example) is a device in which the tape is cut. Intended for safety, this paper storage mechanism is characterized by a paper sheet storage mechanism in which a plurality of receiving plates 26 are installed on a mounting table 25, and is also disclosed in Japanese Patent Application Laid-open No. 158021/1983 (second known example). This provides a clamping mechanism for simply compressing and clamping paper sheets, in which the clamping plate 24 can be biased in the direction of approaching each other by a clamp arm 18 that is linked to the lowering of the second support shaft 8. Furthermore, in Japanese Patent Application Laid-Open No. 60-158022 (third known example), a bundle of paper sheets held by a holding arm 31 is rotated by 90 degrees together with the holding arm 31 by moving a clamp rod 36 in the longitudinal direction. The paper sheet Tokaiden mechanism for making paper sheets
8023 (fourth known example), a heater 41 biased by a spring and a cutter body 42 are separately installed on a heater arm driven by a solenoid 43, and the heater 41
A device is described in which the tape is pressed by a cutter body 42 to adhere the ends of the tape, and at the same time the tape is cut by a cutter body 42.

[5 that the invention attempts to solve! [Problem] Although each of the above-mentioned known examples can sufficiently fulfill the function of achieving the intended purpose, they all have unresolved problems as described below.

■ First known example.

In order to safely support paper sheets, it is necessary to provide a large number of receiving plates 26 +f, which complicates the structure and causes failures.

■Second known example.

The clamp arm 18 biases the clamping plate 24 to indirectly clamp paper sheets, and although it requires a strong driving force, the force for clamping the paper sheets is weak, resulting in power loss. stood at 11.

■ Third known example.

A complicated rotation drive aS was required to rotate the paper sheet 90 degrees.

■ Fourth known example.

The heater 41 adheres the tape and at the same time the cutter body 42 cuts the tape, and in the unlikely event that the adhesion is insufficient, the tape can be removed from the following unused tape without bundling the paper sheets. There was a risk of it being cut off.

[Means 9 and Effects for Solving the Problems] In order to solve each of the above-mentioned ff problems, in the present invention, a bundle of paper sheets supplied on a rotatable and vertically movable table is arranged in advance by an aligning means. After arranging the tapes and then linking the starting ends of the tapes from the tape supply means to the bundle group, the first!
The clamping means strongly pinches the bundle group together with the starting end of the tape, and the bundle group is rotated a required number of times together with the table to surround the tape around the outer periphery of the bundle group. The next bundling is carried out, the unused tape is cut by the cutting means, and the first bundle group is released from the first clamping means, and the second clamping means is disposed above the first clamping means. The group of bundles is clamped by the second clamping means, and the clamping pressure of the second clamping means is increased while the bundle group is rotated by 90 degrees with the second clamping means to stand up, and then the second clamping means is released. At the same time, the first clamping means grips the bundle group again, the table is further rotated to supply tape to surround the outer periphery of the bundle group, and the first clamping means binds the bundle group with the tape so that it is perpendicular to the bundle group. It is configured like a large bundle binding machine for paper sheets that can freely bind groups of paper sheets with tape, and by simply turning on the start switch, it can sequentially and fully automatically bind groups of paper sheets with tape. After wrapping the bundle into a large bundle and turning the large bundle 90 degrees to perfect the binding, the tape was wound separately, resulting in a cross-shaped tape. In addition, the large bundle can be rotated through 90 degrees by simply reinforcing its clamping state, resulting in a simple structure.

To explain with reference to the figure, the first
The clamp 63 has a notch 65 in a sleeve 64 provided at the lower end of the connecting frame 62' vertically disposed on the guide body 62.
A pin 64' projecting inward from the sleeve 64 is movably engaged with a substantially parallelogram-shaped loop-shaped cam groove 66 recessed on the outer periphery of the sleeve 64. In contrast, a second clamp member 63'ζ, which is provided oppositely on the same axis, is rotatably and slidably supported within a sleeve 64'. (Refer to Figure 1.6) The detailed configuration of this embodiment will be explained together with its operation. In the figure, 7 shown in Figure 3 represents a small bundle (bI
bz...) is an alignment means, and a crank 73 having a follower 72, in which a cam 71 is rotated by starting an alignment motor M8.

A matching rod 74 connected to this is advanced along a guide groove 76 using a support shaft 75 as a fulcrum, and the small bundle bl b
z..., and what is shown in FIG. 7 is an indexing means 8 of the table means 2.
3 is rotated every 90 degrees, solenoid 81
The locking body 84 can be freely engaged and detached from the positioning hole 83 formed in the table base 82 by releasing or applying the force. Regarding the shutter means 2 shown in FIG. 4, the small bundle b
The input of l bz... and the removal of the large bundle B are carried out through an opening 93. In order to ensure safety, a shutter 92 is provided in the opening 93 so that it can be slid open and closed. It is configured to be movable in the left and right direction (direction perpendicular to the plane of the paper in 4th rA) by a shutter motor M9 via a ninth transmission means G9 such as a sprocket.

Next, the operation of this embodiment will be explained.

■ When the required number (for example, 10 bundles) of small bundles of paper sheets, bz, etc. are placed on the first process table 23 and the start button (not shown) is turned on, the shutter motor M9 starts. The shutter 92 opens the opening 93 via the ninth transmission means G9.
Close.

At the same time, the alignment motor M8 starts, the cam 71 rotates, and the crank 73 having the follower 72 rotates clockwise in FIG. Rotating in the same direction within the guide groove 76,
After aligning each of the small bundles bl bz... with reference to the backing plate 100 fixed on the table opposite to this, the motor M8 is rotated once and the aligning rod 74 is retracted to the original position. . (See Figure t58 (A)) 0 Second step The solenoid 81 of the indexing means 8 shown in Figure 7 is energized,
The locking body 84 is disengaged from the positioning hole 83 against the force of the spring 85, and in this state, the table rotation motor M2 is started, and the table 23 is rotated 90° counterclockwise in FIG. 2 via the second transmission means G2. Turn and stop.

At or slightly before this position, the biasing force of the solenoid 81 is released and the table base 82 is fixed by the locking body 84.

■ Third process The tape arm motor M5 starts, and the tape arm 42 rotates counterclockwise in FIG. 2 via the fifth transmission means G5, approaches the small bundle group b+ bz, and stops once. At the same time, the feed motor M4 is driven by a predetermined amount so that the starting end of the tape is in the small bundle group blb2, 1, . and the clamp plate 32.

(See Figure 8 (B)) ■ Fourth step Next, the clamp motor M3 is started, and the third transmission means G
The pinion 35 of No. 3 is rotated, the pair of racks 34 meshing therewith are started relative to each other, the guide 33 is moved toward each other on the guide rod 31, and the pair of clamp plates 32 are moved toward each other on the guide rod 31.

! Evacuate to the original position so as not to interfere with movement. (8th
(See Figure (C)) 5th step The solenoid 81 of the indexing means 8 is energized, the table rotation motor M2 is started, and the table 23 is rotated twice (720 ') let and stop.

In this case, the feed motor M4 is not driven simultaneously with the rotation of the table 23, and the tape T is pulled out from the reel R by rotating the table 23 against the tape clamping force of the drive roller 43 and the seven reel roller 44. This is done by

As a result, on the outer periphery of the small bundle group bl bz..., 2
The tape T will be wrapped strongly in a layered manner.

Incidentally, as the tape T is pulled out due to the rotation of the table 23, the tape arm 42 may be rotated by the table 23, but this rotation is detected by a switch (not shown) and the tape arm motor M5 is driven at any time. , is controlled to stay at the original position.

Furthermore, when winding the tape T in the longitudinal direction of the small bundles b2..., only the center in the longitudinal direction of the small bundles b,... is clamped by the clamp plate 32; There is a risk that the longitudinal end of the tape T may be bent in the winding direction when the tape T is wound.
It is regulated by 6 and rolled into a perfect square shape.

(See Figure 8(C)(D)) ■　6th step The indexing means 8 fixes the table 23 again.

The heat arm motor M6 starts and the sixth transmission means G
6, the heater arm a1 is moved to the second position against the spring S3.
Turn the heater 53 clockwise to the clamp plate 32.
The tape T is heated and welded by sliding the tape T over the top, and as the arm al continues to rotate, the heater arm a2 and the support arm a3 each release the spring S4. S
5, the cutter 54 forms a large bundle B and cuts the fixed tape T and the following unused tape T.

Next, the heat arm motor M6 reverses, and the arms a1 to a3 are retracted to their original positions.

Note that after cutting the tape T by the cutter 54, the end of the tape T remaining in the tape supply means 4 remains in a state protruding from the guide 41, which causes inconvenience in supplying the starting end of the tape T during the next bundling. However, this problem can be solved by rotating the feed motor M4 of the tape supply means 4 in the reverse direction by a predetermined amount, or by rotating the feed motor M4 in the reverse direction until the starting end of the tape T is detected by a sensor (not shown).

■ In the seventh step, the first indexing means releases the lock on the table 23,
The table rotation motor M2 moves the table 23 further 90 degrees while keeping the large bundle B with the tape T wound only on the side in a2F.
'As the table is rotated, the table up and down motor M1 starts, and 2i'! 1. The pinion 25 is driven through the first transmission means G1 to operate the rack shaft 22 to raise the table 2-3 to a raised position of a required height, and extract the large bundle B from between the clamp plates 32. Second clamp element 63.63'
Deploy it to flj. (See FIG. 8(E)) ■ Eighth step The primary clamp switch Swl is turned on, the clamp twist remoter M7 is started, and the clamp twist remoter M7 is moved along with the guide body 62 on the guide rod 61 via the seventh transmission means G7. The first clamping element 63 is approached toward the second clamping element 63',
:jS When the primary switch Swl is turned on and the large bundle B is clamped, the clamp twist remoter M7 is stopped, the clamp motor M3 is reversed, the pair of clamp plates 32 are released, and the large bundle B is released from this clamp plate 32. is,
At the same time, the table 23 is clamped only by the clamp members 63 and 63', and the table lifting motor M1 is reversed to move the table 23 downward to its original position via the first transmission means G1.

(9) Step When the clamp twist remoter M7 is restarted from the state of the 8th step, the first clamp element 63 moves forward against the spring 65 as shown in FIG. 6, and as a result, the cam groove 66
', the pin 64' moves in the direction of the arrow, and this causes the first
The clamping element 63 is twisted about its axis within the sleeve 64, and along with this, the large bundle B is also turned 90' together with the second clamping element 63'. Whether or not the clamping action has been performed to the extent that this twisting action is performed is determined by whether or not the secondary switch Sw2 is turned on, and when the secondary switch Sw2 is turned on, the drive of the clamp twisting remoter M7 is stopped. be done. (See Figure 8 (F)) ■ In the 1st O process, the first clamp member 63 retracts to release the large bundle B by reversing the clamp twist remoter M7, and afts the large bundle B onto the table 23. Then, the table lift motor M1 is operated to lower the table 23 to a lowered position of a required height, and at this lowered position, the second to sixth
After the process is completed, the tape T is wound around the large bundle B from another direction. (See Figures 8 (G) and (H)) ■ After completing the cross-shaped tape binding work on the large bundle B in the 11th step, the table rotation motor M2 is started and the table 23 is rotated 90 degrees again.
At the same time, the table 23 is raised to the raised position by the table lift motor M1, and the clamp plate 32 is pulled out from between the large bundle B and the tape 1. Thereafter, the clamp motor M3 is reversed to remove the clamp plate 32 from the large bundle B. At the same time, the table 23 is lowered to its original position by the table lift motor M1. (See FIG. 8(H)) O-12th step The shutter motor M9 is reversely rotated, the shutter 92 is opened, and the large bundle B can be taken out from the opening 93.
