Referring to this figure and FIG. 5, the present invention has a band settling portion 6 in which a roll paper band Ba wound around a roll is formed.

The band settled portion 6 is placed with the roll paper band Ba free. The band B unrolled from the roll paper band Ba is guided to the guide 7 to pass through the band pull and feeder unit 10.

The band pulling and feeding device 10 includes upper and lower rollers 11 and 11 'for pulling and upper and lower rollers 12 and 12' for feeding. It is usually installed side by side.

Referring to FIG. 6, the lower roller 11 'for pulling and the lower roller 12' for feeding are rotated by transmitting power through shafts 13 and 13 'and gears 14 and 14'. have. As shown in FIG. 7, the power of the motor 15 is transmitted to the one gear 14 'through the belt 16 and the pulley 16'. And the gear 14 in engagement with the gear 14 'is rotated.

Therefore, the gears 14 and 14 'that are engaged are rotated in opposite directions to each other.

Among them, the gear 14 associated with the lower roller 11 'for pulling is adapted to transmit or decrease its power in transmitting power to the shaft 13.

6 and 8, the lower roller 11 ′ for pulling is configured such that the washer 17 and the slip bearing 18 are installed at both ends of the gear 14 at the rear end of the shaft 13.

In addition, the washer 17 coupled to the rear end is configured to press the pressing protrusion 19a of the pressing table 19, the pressing table 19 by the control mechanism 20 is supported on the main body (1) It can be moved in the forward and backward directions. Reference numeral 21 is a resilient member having a function of preventing the flow of the control member 20 to give elasticity in the outward direction, reference numeral 22 denotes a hinge shaft of the control member presser 19, and 23 denotes a bearing.

Referring to FIG. 9, when the adjuster 20 is rotated to the left or the right, the nut 24 is moved forward or backward so that the presser 19 is moved forward or backward about the hinge shaft 22. .

Accordingly, the pressing protrusion 19a of the pressing table 19 presses the washer 17 strongly or vice versa.

Therefore, when the pressure is strongly applied, since the slip bearing 18 including the washer 17 is in close contact with the gear 14, the slip frequency of the gear 14 decreases, so that the lower part for pulling including the shaft 13 is reduced. The rotation speed of the roller 11 'is increased.

In addition, when the pressure is weakly reversed, the rotational speed of the lower roller 11 'for pulling becomes slow.

That is, the gear 14 is in a state of slipping from the shaft 13 and the shaft 13 is rotated by the friction force between the slip bearing 18 and the shaft 13 including the washer 17 in close contact with the gear 14. will be.

And it is possible to adjust the rotation speed of the lower roller 11 'for pulling, but will be described later to adjust the pulling speed of the band (B).

Next, the configurations of the pulling top roller 11 and the supply top roller 12 will be described with reference to FIGS. 10 to 13.

The upper rollers 11 and 12 for pulling and supply are rotatably installed on both sides of the roller link 26 rotated to the left or right side about the hinge shaft 25, respectively, and the lower side for the pulling and supply respectively. The lower rollers 11 'and 12' are positioned.

In addition, the cam 30 by the cam link 28 to the rotational movement defined around the hinge axis 27 and the joint link 29 to transmit the rotational movement of the cam link 28 to the roller link 26 It's supposed to be transmitted.

The roller link 26 is adapted to adjust the degree to which both sides are positioned around the hinge shaft 25.

In detail, when the adjusting bolt 31 is rotated, the adjusting hole 33 connected to the roller link 26 through the long hole 32 moves to the left or the right. Accordingly, the lower end of the roller link 26 moves about the hinge shaft 25 and thereby the pulling and supplying upper rollers 11 and 12 can maintain the horizontal state or adjust their position appropriately. Here, reference numeral 34 denotes an elastic member for imparting tension.

10, 14A, and 14B, the band pulling and supplying unit 10 has a band setting portion 34. This band setting section 34 is used when hanging the band (B).

The band setting unit 34 has upper and lower guides 35 and 36 installed in the middle portion of the roller link 26 in the up and down directions, and is installed in the lower guide 36 to move forward and backward. It has a movable member 37 possible. In addition, one end of the moving member 37 is provided with a handle member 37a.

And the moving member 37 receives the elasticity of the elastic member 38 has a state that always receives a force inward. In addition, there is a locking member 39 that prevents the detachment of the elastic member 38, the upper portion of the locking member 39 has a passage groove (39a).

The operation of the band setting unit 34 will be described. The band setting unit 34 is used to pull out the band B from the roll paper band Ba and to set the band pulling and feeding device 10.

That is, as shown in FIG. 14A, the moving member 37 is in a state of blocking the passage part 40 between the upper and lower guides 35 and 36. Therefore, the band B passing through the passage 40 between the upper and lower guides 35 and 36 does not leave the passage 40.

In addition, the band B passing through the upper and lower rollers 11, 11 '(12, 12') for pulling and supply is not released to the outside, thereby preventing malfunction.

On the other hand, when it is necessary to set again by consuming all of the roll paper band Ba and replacing it with a new one, or when it is necessary to set the band B to the band pulling and supplying unit 10 again due to a malfunction. First, grab the handle member 37a and pull it outward.

In this case, the moving member 37 moves to the outside, and the handle member 37a connected to the moving member 37 passes through the passage groove 39a of the locking member 39.

Next, when the handle member 37a is rotated, the handle member 37a is in a standby state that is caught by the locking member 39 as shown in FIG. 14B.

In this state, since the passage part 40 is opened, the band B can be inserted into the passage part 40 between the upper and lower guides 35 and 36.

Next, in order to prevent the band B set as described above from leaving the passage 40, the handle member 37a is rotated to be positioned in the passage groove 39a so that the handle member 37a is locked. 39, which is passed by the force of the elastic member 38, the moving member 27 intercepts the passage 40 to shield as shown in Figure 14a.

Therefore, the band B passing through the passage 40 between the upper and lower guides 35 and 36 is set so as not to be separated by being blocked by the moving member 037, and thus the band pulling and feeding device part during operation. There is no deviation of the band B in (10) and no malfunction occurs at all.

In addition, the lower rollers 11 'and 12' are not rotated.

In addition, this state is when it is in a standby state as shown in FIG. 5, and in operation, the band B is pulled backward and the front feeding is performed.

First, when the band B is pulled backward, as shown in FIG. 12, as the cam 30 rotates, the lower end of the roller link 26 is pulled to the right, thereby centering the hinge shaft 22. As the roller link 26 rotates, the upper roller 11 for pulling is brought into close contact with the lower roller 11 'and the lower roller 11' is rotated at high speed by receiving power.

At this time, the lower roller (11 ') is rotated in the counterclockwise direction, the band (B) is moved to the rear pulled state, whereby the reference to the guide shown in Figure 5 floating in the air by the band guide (2) The band B that was present is pulled and pulled up, whereby the bundle of articles K is bundled.

Next, when this process is completed, it is operated in a neutral state as shown in FIG. 11, and after the band bonding and cutting process is completed, the band B supply process is performed as shown in FIGS. 13 and 15.

At this time, the lower end of the roller link 26 is pulled by the rotation of the cam 30 so that the upper roller 12 for supply is in close contact with the lower roller 12 'and at the same time the lower roller 12' is driven at a high speed in the clockwise direction. The band B is fed forward by rotation.

These operations are operated only for a predetermined time, thereby supplying a band B of an appropriate length.

In addition, when the supply is completed, it is operated in a neutral state as shown in FIG. 11 to be in a standby state. For reference, the band supply process as described above corresponds to the final process of one cycle of the paper band bending system to which the present invention is employed.

According to the above description, the present invention facilitates the band pulling operation and the band supply operation for tying the bundle bundle with the paper band, and the article such as the document or letter bundle which is easy to be damaged since the operation is performed without the band being cut or detached. It provides an effect that can be easily tied without breaking.
