The lower end of the tape holding body 23 is rotatably supported on the same shaft 31 on which the above-mentioned tape holding body 22 is supported. Arm 3 extending toward the pressure receiving member 26 side of the tape holding body 23
A round rod-shaped pin 40 is fixed to the end of 9 so as to be parallel to the fixed roll 13. The tip of the arm portion 41 extending from the position of the pin 40 to the opposite side faces the outer peripheral surface of a shaft 42 described later when the arm end portion 5 is separated from the pressure receiving base 3. The stopper 43 fixed to the frame 21 is provided to receive a substantially intermediate position of the tape holding body 23 in the vertical direction when the arm end portion 5 is separated from the pressure receiving base 3.

Further, as shown in FIGS. 5 and 6, the L-shaped members 24 are provided on both sides of the frame 21 when viewed from the front of the device.
And the I-shaped member 25 is located. A portion of the L-shaped member 24, which is slightly closer to the pressure receiving member 26 from the longitudinal middle position, is rotatably supported by a shaft 44 fixed to the frame 21. A claw 45 that bends toward the inside of the apparatus is formed at the upper end of the bent portion of the L-shaped member 24, and the rear end of the L-shaped member 24 is rotatably supported by an oval I-shaped pin 46. It is connected to the lower end of the member 25. The upper end of the vertically extending I-shaped member 25 is fixed to the shaft 42, and the shaft 42 is loosely fitted in a vertically extending long groove 47 formed in the frame 21. Further, one end of the coil-shaped spring member 49 is attached to the shaft support pin 46 and is attached to the lower end of the other end frame 21. Therefore, when the arm end portion 5 is separated from the pressure receiving base 3, the L-shaped member 24 is horizontal with respect to the center of the shaft 44, and the shaft 42 to which the I-shaped member 25 is fixed is attached to the lower end of the long groove 47. The spring member 49 is formed so as to pull so as to abut.

In this embodiment, the adhesive tape is used to join the winding tape 4a and the winding end portion, but a heat-welding tape can also be used. In this case, a heater may be built in the pressure receiving member 26. it can.

Next, the operation will be described. First, first pull out the tip of the winding tape 4a from the winding tape 4 shown in FIG.
From the guide rod 2a of the bundling arm 2 shown in FIG. 2 through the pressure bonding roll 11 of the arm end portion 5, the pin 40 provided on the tape holding body 23 of the pressure receiving base 3 and the fixing roll 13 provided on the tape holding body 22 are provided. Hold it in between. At this time, the arm end portion 5 is in a chain line state, the space between the arm end portion 5 and the pressure receiving base 3 is open so that the material 6 to be bound is pushed, and the winding tape 4a is stretched between the two. The object to be bound 6 is pushed into the wound tape 4a and the binding arm 2 is tilted (FIG. 1).

In the state shown in FIG. 1, the end of the winding tape 4a is clamped between the pin 40 and the fixed roll 13 while the object to be bound 6 is already wound around the winding tape 4a in a semicircle. With
The winding tape 4a is guided by the arch portion 14.

When the arm end portion 5 is further lowered from the state shown in FIG.
As shown, the first pressing member 7 presses the winding tape 4a and the end portion onto the pressure receiving member 26, and at the same time, the second pressing member 8 is pressed.
The winding tape 4 extending to the pressure receiving member 26 by the pressure bonding roll 11 of
The middle of a is pressed onto the fixed roll 13. During this time, the inclined portion 19 of the arm end 5 is lightly rotated from the surface 19a to the surface 19b.
0, the tape holder 22 is a spring member.
Turn right against 35,36. On the other hand, the tape holding body 23
Does not turn right due to the tip of the arm portion 41 contacting the outer peripheral surface of the shaft 42.

When the arm end portion 5 further descends from the state shown in FIG.
As shown in the figure, the winding tape 4a includes a pin 40 and a fixed roll 13
Although it is cut by the cutting blade 9 in between, the winding tape 4 still remains.
The end of the winding tape 4a extending from the device is held between the pressure roll 11 and the fixed roll 13. At this time, the surface 19c of the arm end portion 5 contacts the claw 45 of the L-shaped member 24 and presses it downward, so that the L-shaped member 24 turns left about the shaft 44, and the I-shaped member 25 moves. Since 42 is loosely fitted along the long groove 47, it is pushed up. As a result, when the shaft 42 is disengaged from the tip of the arm portion 41 of the tape holding body 23, the tape holding body 23 rapidly turns right by the bias of the spring member 35. This right turn causes the pin 40 of the arm portion 39 to rise from the position shown in FIG. 2 and pull up the cut end of the winding tape 4a. The tape holding body 23 stops when the pin 40 comes into contact with the arch portion 14. FIG. 3 shows the lowest point of the arm end portion 5 of the binding arm 2, and next turns to ascend.

FIG. 4 is a view showing the rise of the arm end portion 5 after cutting the winding tape 4a. Since the binding arm 2 is pulled up after the winding tape 4a is cut, the arm end portion 5 also rises. Pin 4
When 0 is released from the contact with the inclined portion 15a of the arm portion 14 while following the inclined portion 15a, the tape holding body 23
By the spring member 35, the tape is further rotated rightward to the tape holder 22 side, and the remaining portion of the winding tape 4a on the pin 40 is
Since it is free from the holding surface side of the pin 40 and is below the pin 40, the remaining portion of the winding tape 4a is not narrowed between the pin 40 and the fixed roll 13. And the pin 40 which turned
Abuts on the outer peripheral surface of the fixed roll 13 to hold the end of the winding tape 4a extending from the winding tape 4. At this point, the surface 19c releases the pressing force of the L-shaped member 24 on the claw 45, so that the L-shaped member 24 moves toward the spring member 49.
However, since the arm portion 41 of the tape holding body 23 is in contact with the outer peripheral surface below the shaft 42, the tape holding body 23 is slightly on the upper right side about the shaft 44. When the arm end portion 5 further rises, the surface 19b moves away from the contact with the rotating roll 20, so that the bias of the spring member 35 causes the tape holding body 22 and the tape holding body 23 to move closer to each other. Moreover, the tape holding body 2 is urged by the biasing force of the spring member 36.
3 turns left to the stopper 43 and stops. Therefore, the tip of the arm portion 41 faces the outer peripheral surface of the shaft 42,
The tape holding body 23 and the tape holding body 22 return to the initial position and are pulled by the pulling force of the spring member 49 shown in FIG.
The L-shaped member 25 and the L-shaped member 24 are returned to their original positions.

In this way, the first pressing member 7, the second pressing member 8, the cutting blade 9, and the arm end portion 5 having the inclined portion 19 are lowered, so that the binding side between the first pressing member 7 and the pressure receiving member 26 is increased. Holding the winding tape 4a, while holding the portion of the winding tape 4a spaced from the pressure receiving member 26 between the second pressing member 8 and the fixed roll 13 and pinching between the two places. Position 40 and wrap tape between this pin 40 and fixed roll 13.
After cutting the winding tape 4a by cutting the winding tape 4a with the cutting blade 9, the tape holding body 23 rotates rightward so as to separate from the pressure receiving member 26, so that the cut end of the winding tape 4a on the side of the bundled object 6 is pin 40. Will be on the lower side. This surely prevents the cut end of the winding tape 4a on the side of the object to be bound 6 from being pinched by the pin 40 and the fixed roll 13, and pulls out the end of the wound tape 4a from the pin 40 and the fixed roll 13. With this, it is possible to reliably hold the sheet.

(Effects of the Invention) From the above, the cutting end after cutting the wound tape extending from the object to be bound is surely freed by the turning of the tape holding body, and the cutting end that has been conventionally used is freed. It is not necessary to use the tape pull-back plate that descends together with the cutting blade. In particular, since the winding tape is cut while being pushed up by the tape holder, the winding tape can be cut cleanly.
