A support rod 41 of the tape pressing member 38 is slidably supported by a support plate 42 provided between the arm pieces 2 and 3.
A biasing spring 43 is provided between the support plate 42 and the support plate 42 .

This causes the tape pressing member 38 to press against the biasing spring 43.
is urged to protrude from the tip of the binding arm 1 (
(see Figure 1), the tape pressing member 3 is lowered by lowering the binding arm 1.
8 comes into contact with the tape crimping table 34, the guide plate 3
It is designed to be recessed into the distal end of the binding arm 1 along 9°40 (see Fig. 2).

Reference numeral 44 denotes an operating handle attached to the outer side of the tip of the binding arm 1, and 45 and 46 indicate a cutting blade and a tape clamping claw member attached near the guide plate 40, respectively.

The printing powder and powder supply roller 16 may be replaced with a roller provided with ink and an ink pad.

To use the binding machine with a printing device of the present invention configured as described above, a printing agent, such as printing powder, is poured into the tank 17, and the tape 13 is mounted on the reel 12 through the tape mounting opening 32. Then, pull out the tape from the reel 12 with the adhesive side facing upward, pass the drawn tape between the pressure roller 18 and the printing roller 15, and pass it over the guide rollers 10 and 11 of the binding arm 1 that is standing up. When the leading end of the tape receiver is clamped by the tape clamping claw 35 of the stand 33 and the tape clamping claw insertion hole 36, the state shown in FIG. 1 is reached, and the preparation for bundling is completed.

In this state, the center of the pressing roller 18 is on a line connecting the center of the pivot shaft 4 and the center of the printing roller 15, and the tape 13 is pressed against the printing roller 15 via the urging spring 24.

Therefore, when the tape receiver places a bundle of objects to be bound on the object placement plate 37 by pushing the tape stretched between the stand 33 and the tip of the binding arm 1, the tape 13 is transferred to the reel 1.
It is drawn from 2.

As the tape 13 is drawn out, the pressure roller 18 and the printing roller 15 rotate, and the rotation of the printing roller 15 also rotates the powder supply roller 16, so that the printing powder in the tank 17 is transferred to the printing roller by the powder supply roller 16. 15, and the tape is compressed by the press roller 18 and the printing roller supplied with printing powder, so that printing is performed on the adhesive surface of the tape.

Next, when the binding arm 1 is lowered using the operating handle 44, the pressure roller 18 and the guide rollers io and i1 each move counterclockwise around the pivot shaft 4, so that the passed tape is not hung on these rollers. is separated from the printing roller 15, and printing is no longer performed.

Further, as the binding arm 1 descends, the pivot shaft 4 rotates counterclockwise, and the sector gear 26, gears 27, 28, and booley 29 rotate.
The small pulley 30 rotates via the belt 31, and the reel 12 rotates counterclockwise via the friction clutch, rotating shaft 14, and one-way clutch, thereby rewinding the tape.

When the tape becomes tense after rewinding, the friction clutch built into the small pulley 30 slips and the reel 12
stops.

Since the tape is separated from the printing roller 15 during the tape rewinding process, no double printing occurs.

Both ends of the tape around which the object to be bound is wound are crimped by the pressure contact between the tape pressing member 38 and the tape crimping table 34, and when the binding arm is further lowered, the tape pressing member 38 is pressed against the tape crimping table 34. Guide board while maintaining 39.4
0 is lowered, the cutting blade 45 and the clamping claw are pushed back, and the member 46 is also lowered, and the tape is cut. sandwiched between.

When the binding arm 1 is raised using the operation handle 44, the member 46 moves up and leaves the clamping claw 35, and at the same time the clamping claw 35 rotates clockwise and is inserted into the clamping claw insertion hole 36. , pinch the tip of the tape.

In the process of the binding arm 1 returning to the upright state shown in Fig. 1,
Although the tape 13 is pulled out from the reel 12, since the tape and the pressure roller 18 are separated from the print roller 15, no printing is performed on the tape.

When the binding arm 1 has returned to its standing position, the state shown in FIG. 1 is reached, and the preparation for the next binding is completed.

If you set the length of the tape to be pulled out while printing by pushing the tape into the object to be bound to be approximately 70 to 90% of the length of tape required for binding, then 1 of the outer circumference of the binding
It is preferable that 0 to 30% remain as printing pitch space.

As can be easily understood from the above explanation, according to the present invention, adhesive tapes can be easily bound while printing necessary information on them.
