With this configuration, the tape holder 20 is connected to the tape clamping body 21.
is biased in the direction of approaching. Further, one end of a coiled spring member 32 is attached to the lower part of the side plate 25, and the other end is attached to the front plate 33 of the frame 19. The holding body 20 is provided so as to be biased toward the pressure receiving member 18 .

As shown in FIGS. 5 and 6, the tape holding body 21 is composed of two substantially T-shaped plate members facing each other, and is positioned on both outer sides of the tape holding body 20. As shown in FIGS. The lower end of the tape holding body 21 is connected to the same shaft 2 on which the tape holding body 20 described above is supported.

The upper end of the vertically extending I-shaped member 23 is fixed to a shaft 37, and the shaft 37 is loosely fitted into a vertically extending long groove 42 formed in the frame 19. Furthermore, one end of the coiled spring member 43 is attached to the pivot pin 41, and the other end is attached to the lower end of the frame 19. Therefore, when the arm end 5 is away from the pressure receiving base 3, the shaft 37 to which the I-shaped member 23 is fixed is aligned with the long groove 42 so that the L-shaped member 22 is horizontal with the shaft 39 as the center. A spring member 43 is formed to be pulled so as to come into contact with the lower end of.

In this embodiment, an adhesive tape is used to join the winding tape 4a and the winding end, but a heat-fusible tape can also be used, and in this case, a heater may be built into the pressure receiving member 18. can.

Next, its effect will be explained. First, let's start with Part 8.
The tip of the winding tape 4a is pulled out from the bundle tape 4 shown in the figure, and passed from the guide roll 2a of the binding arm 2 shown in FIG. 2 to the pressure roll 12 of the arm end 5.
Pin 35 provided on the tape clamping body 21 of the pressure receiving table 3
and a fixed roll 27 provided on the tape holder 20. At this time, the arm end 5 is in the shape of a chain line, and the distance between it and the pressure receiving table 3 is open so that the object to be bound 6 is pushed in, and the winding tape 4a is disposed between the two. The object to be bound 6 is pushed into the wound tape 4a provided, and the binding arm 2 is tilted (the first
figure).

In the state shown in FIG.
While being wound approximately half a circumference by a, the end of the wound tape 4a is held between the pin 35 and the fixed roll 27, and the wound tape 4a is guided by the guide member 9. .

When the arm end 5 further descends from the state shown in FIG. 1, the first pressing member 7 presses the winding tape 4a and the end onto the pressure receiving member 18, as shown in FIG.
At the same time, the pressure roll 12 of the second pressing member 8 presses the middle of the winding tape 4a extending toward the pressure receiving member 18 onto the fixed roll 27. During this time, the inclined portion 16 of the arm end 5 is gently moved from the surface 16a to the surface 16b by the rotating roll 1.
7, the tape holder 20 rotates to the right against the spring members 30, 32. On the other hand, the tape holding body 21 does not turn to the right because the tip of the arm portion 36 comes into contact with the outer peripheral surface of the shaft 37 .

When the arm end 5 further descends from the state shown in FIG. 2, the cutting blade 10 cuts the wound tape 4a as shown in FIG. and is cut by the cutting blade 10 located between them. At this time, the end of the winding tape 4a extending from the winding tape 4 continues to be held between the pressure roll 12 and the fixed roll 27. At this time, the surface 16c of the arm end 5 contacts the claw 40 of the L-shaped member 22 and presses it downward, so the L-shaped member 22 turns to the left about the shaft 39, and the I-shaped member 23 37 is loosely fitted along the long groove 42, so it is pushed up. As a result, when the shaft 37 disengages from the distal end of the arm portion 36 of the tape holder 21, the tape holder 21 rapidly turns to the right due to the bias of the spring member 30. This rightward rotation causes the pin 35 of the arm portion 34 to rise from the position shown in FIG. 2 and pull up the cut end of the wound tape 4a. The tape holding body 21 stops when the pin 35 comes into contact with the guide member 9. FIG. 3 shows the lowest point of the arm end 5 of the binding arm 2, which then begins to rise.

FIG. 4 is a diagram showing the rise of the arm end 5 after the winding tape 4a is cut, and after the winding tape 4a is cut,
As the binding arm 2 is pulled up, the arm end 5 also rises, but at this time the pin 35 touches the inclined part 1 of the guide member 9.
4a and is released from the contact, the tape holding body 21 further rotates to the right toward the tape holder 20 by the spring member 30, and the wound tape on the pin 35 is removed. The remainder of 4a is free from the pin 35.

The pin 35 that has turned to the right comes into contact with the outer circumferential surface of the fixed roll 27, thereby clamping the end of the wound tape 4a extending from the wound tape 4. At this point, the surface 16c releases the pressure on the claw 40 of the L-shaped member 22, so the L-shaped member 22
The tape gripper 2 returns to a nearly horizontal position.
Since the arm portion 36 of No. 1 is in contact with the lower outer peripheral surface of the shaft 37, it is slightly upwardly tilted to the right about the shaft 39.
As the arm end 5 further rises, the surface 16b
The tape holder 20 and the tape clamping body 21 move closer together due to the biasing force of the spring member 30, and the biasing force of the spring member 32 causes the tape holder 20 and the tape clamping body 21 to move closer together. Tape clamping body 2
1 turns left until it reaches the stopper 38 and stops. Therefore, the tip of the arm portion 36 faces the outer circumferential surface of the shaft 37, and the tip end of the arm portion 36 faces the outer circumferential surface of the shaft 37, and the tape holding body 21 and tape holder 2
0 returns to the initial position and is pulled by the I-shaped member 23 and L by the pulling force of the spring member 43 shown in FIG.
The character-shaped member 22 is returned to its original position.

In this way, the first pressing member 7 and the second pressing member 8
By lowering the arm end 5 having the cutting blade 10 and the inclined part 16, the wound tape 4a is positioned between the guide members 9, guided, and cut by the cutting blade 10 provided therebetween. Therefore, the winding tape 4a
The wound tape 4a can be cut accurately without deviating from the width of the cutting blade 10 and without tearing.

(Effects of the Invention) As described above, by being able to cut the wound tape accurately, the leading edge of the cut tape becomes clean. Furthermore, the operator is freed from the trouble of adjusting the width of the winding tape to the width of the cutting blade, making the bundling work easier and improving work efficiency.
