In the figures and FIG. 4, reference numeral 70 is a micro switch that is activated when the tension of tape b exceeds a predetermined value due to the tape winding operation of reel 20, and stops the rotation of reel 20 in the Q direction.

Next, the operation of this embodiment will be explained.

FIG. 10 shows the initial setting position of the device of this embodiment, and as is clear from this figure, the endless chains 16, 16 have four guide pins 17a, 17b, 1
7c and 17d are stopped at a position on the lower running path B, and the tip g of the tape b fed out from the reel 20 is clamped by a fastener 19.
The portion of the tape b fed out from the reel 20 contacts the tape swinging surface 36 of the swinging arm 32 and is stretched between the fastener 19 and the reel 20 in a bent state. The swing arm 32 is in the right rotation position, and the running path D of the endless chains 16, 16 is
It's out of place.

Next, when the endless chains 16, 16 rotate in the P direction due to the rotation of the drive sprockets 15, 15, the guide pins 17a, 17b, etc. move in the same direction, and first the first guide pin 17a moves in the direction P. and guide it in the direction P along the chain travel path D, as shown in FIG. reel 2
Since tape 0 rotates freely in the Q' direction, tape b is fed out from reel 20.

Then, the second guide pin 17b also comes into contact with the tape b and guides it as shown in FIG. In this way, each guide pin 17a, 17b, 17c,
When 17d reaches the position shown in FIG. 13, the tape b guided by these forms a ring along the ring forming path A.

The endless chains 16, 16 further advance in the P direction, pass through the state shown in FIG.
It stops when it reaches the state shown in figure a, that is, the initial state. During this time, the tape b is supported on the inside by four sets of temporary fasteners 18, 18, .

At approximately the same time that the endless chains 16, 16 reach the state shown in FIG. 15a, the mounting plate 4 moves forward and closes the upper part of the fastener 19 (see FIG. 1). Next, the tape end presser 61 rotates in the R direction, pinching one point of the tip d of the tape b between its tip and the mounting plate 4,
The tape b is fixed between it and the mounting plate 4 at this portion. The clamping pressure member 57 of the fastener 19 continues as shown in FIG. 3 (FIG. 4).
Figure) Rotate in the S direction to open the fastener 19. When the fastener 19 opens, the tape tip d hangs down, but as the tape end push-up plate 67 moves forward, it is pushed up to a position along the lower surface of the mounting plate 4 (see FIG. 15b). During this time, swing arm 3
2 rotates in the T direction to move the portion of the tape b that contacts the tape pressing surface 34 toward the mounting plate 4.

When the swinging arm 34 reaches the position shown in FIG. 16a, the tape end push-up plate 67 retreats, and the tape tip d and the portion of the tape located above the swinging arm 32 (corresponding to the binding end) e and will face each other in close positions (see Figure 16b).

As described above, a ring of tape b is formed along the ring forming path A on the inner side of the pair of chain guide supports 5 and 9. Next, the object to be bound a is placed in this ring, When placed on the placing surface 2 and the placing plate 4, the photoelectric switch 69 is activated.
As shown in FIG. 17, the reel drive shaft 30 and, by extension, the reel 20 are rotated in the Q direction to rewind the tape b. Due to the unwinding force at this time, a force that pulls the tape b located in the ring forming path A inward (diameter reduction direction) acts, and the loop of the tape b is attached to the four sets of temporary fasteners 1.
8, 18... It comes off and undergoes diameter reduction deformation.

As shown in FIG. 18, when the tape b is wound around the object a to be bound, the micro switch 70 for tension detection is activated to stop the reel 20. Next, fastener 19
The clamping member 57 rotates in the reverse S direction S' to clamp the tape b to the fastener 19.

Next, as shown in FIG. 19, the push-up piece 50 moves upward, pushing up the heater support piece 33, pressing the heater 41 supported by it against the portion e corresponding to the binding end of the tape b, and heating it. , this binding end equivalent portion e and the tip portion d (the upper surface of the tip portion d is restrained by the mounting plate 4) are adhered.

Next, as shown in FIG. 20, the cutter 59 rotates (rotates in the V direction in FIG. 4) to cut the tape b along the upper surface of the fastener 19. At this time, as shown in FIG. 20, the cut end j of the tape b hangs down. After the adhesion, the tape end presser 61 rotates in the reverse R direction R', and after leaving the lower surface of the tip d of the tape b, reaches a substantially horizontal position and stops, while the push-up piece 50 moves downward, and accordingly, the heater 41 also separates from the portion e corresponding to the binding end of the tape b.

Next, as shown in FIG. 21, the swing arm 32 rotates slightly forward in the direction of angle T, and the push-up piece 50 moves upward again to push up the heater 41 via the heater support piece 33. At this time, the push-up piece 50
The upward movement height of is made higher than that shown in FIG. As a result of the swinging arm 32 being swung to the left in the figure and the amount of push-up of the heater 41 being increased, the cut end j is guided by the heater 41 and overlapped with the lower surface of the tip d, and is pushed up. It is bonded to the tip d by being subjected to pressure and heat.

As described above, both binding ends d and e of tape b are overlapped and bonded together, but then, as shown in FIG. The state will be as follows. Further, the push-up piece 50 moves downward, the heater 41 returns to its original position, and the swing arm 32 then rotates in the reverse T direction T' and returns to its original position, resulting in the state shown in FIG. .

Incidentally, when the bound object a on the placement surface 2 is taken out, the photoelectric switch 69 operates to rotate the endless chains 16, 16, and the next process of forming a tape wrapping ring is started. Ru.

As shown in the above embodiment, the present invention includes a tape binding means for binding objects to be bound by hanging a flexible tape around objects to be bound and pulling the tape back; A tape pusher that guides and presses the overlapping part of the arranged tapes (the part e corresponding to the binding end in the example) to the starting end of the tape (the leading end a in the example) and adheres the overlapping part and the starting end. A binding machine comprising a moving adhesive and a cutting tool (cutter 59 in the embodiment) for cutting the tape at a position slightly away from the bonding position of the overlapping portion and the starting end toward the tape retraction side. , the tape pushing adhesive includes a swinging arm that swings while guiding and supporting the tape placed under tension in the pull-back path; an adhesive (heater 41 in the embodiment) that presses and adheres the part guided and supported by the arm to the starting end, and the tape pressing adhesive has a swinging arm that swings toward the starting end. At the same time, the adhesive moves forward toward the starting end, guides and presses the overlapping part of the tape stretched in the pull-back path toward the starting end, bonding the overlapping part and the starting end. and the cutting tool is configured to have a first stage motion in which the adhesive member retreats after that, and the cutting tool is operated after the overlapping part and the starting end are in a state of being glued by the first stage motion. and the tape pressing adhesive is configured such that after the first stage motion and the cutting tool are activated, the swinging arm further swings toward the cut end of the tape, and at the same time the adhesive is directed toward the starting end. move forward, guide and press the floating end between the adhesive part and the cut end of the tape to the starting end of the tape, bonding the floating end and the starting end, and then the adhesive moves back and swings. The present invention is characterized in that the arm is configured to have a second stage motion that swings toward the original position.

The present invention has the above-mentioned configuration, and the first stage motion of the tape pressing adhesive bonds both tape binding ends (the starting end and the overlapping part), and the second stage motion bonds the tape starting end at the cut end of the tape. Since it can be bonded to flexible tapes, it is possible to prevent the cut edges from sagging, giving a beautiful finish to the tape bonded area, and also preventing the adhesive from peeling off easily from the cut edges. This drawback of the conventional example can be corrected. Furthermore, since bonding is performed twice at the overlapped portion of both bound ends of the tape, the adhesive strength of this overlapped portion can be improved.
