Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a binding device equipped with a tape rewinding mechanism for rotating a tape reel in a tape rewinding direction in relation to a tilting axis of a binding arm.

Conventionally, in a binding device, a tape reel is rotated in the tape rewinding direction in relation to a tilting axis of a binding arm, and a tape rewinding mechanism is used to unwind the excess binding tape from the binding tape that is not wound around the object to be bound. (6) This conventional tape rewinding mechanism is equipped with a fan-shaped gear that operates in conjunction with the raising and lowering of the binding arm, and a driven gear that meshes with this fan-shaped gear and rotates together with the tape reel. When the binding arm is raised up, the binding arm is brought into contact with the binding tape of the object to be bound, and when the binding tape is pulled out, the rotation of the tape reel moves the binding arm through the tape rewinding mechanism. In order to prevent the transmission from occurring, the fan gear and the driven gear are designed to disengage.However, in the case of this configuration, when the object to be bound is brought into contact with the binding tape, the binding tape is held in contact with the binding tape. When the binding arm is tilted to its axis after being pulled out, the sector gear and the driven gear may not mesh smoothly, and the tape rewinding mechanism may not operate.

When trying to achieve smooth engagement using a wedge-shaped gear and a driven gear, an auxiliary mechanism is required to ensure that the peaks and valleys of each tooth mesh, and the configuration is complicated. becomes.

The present invention has this point! The purpose of this was to make +i, 175+i of the tape rewinding mechanism into a segment, and to engage the chain component in the tape rewinding mechanism that transmits rotational force t7 to the tape reel. The purpose of the present invention is to ensure that the claws are not inserted into the tape reel. a chain component to which rotational force is transmitted; and a chain component having a shape that extends in a direction that embeds in the chain component when the binding arm is tilted, and in a direction that escapes from the chain component when the binding arm is raised. an engaging pawl, and a guide means for guiding the engaging pawl to engage the chain component in relation to the raising and lowering of the binding arm;
The chain component extends in the extension direction of the chain component, and the chain component fire is provided opposite to the engagement pawl, and the chain component fire is provided in the escape direction of the chain component due to the engagement pawl biting into the chain component. and a regulating member that regulates the displacement of 1-t).

The engagement pawl 11 is pivotally attached to the front side of the pin 22 in the figure, and the roller 23 is rotatably supported on the opposite side of the pin 22 via the connecting rod 20'i. Engagement claw 11
consists of a claw portion 11a and a weight portion 11b. As shown in FIGS. 1 and 4, the claw portion 11a is in a direction to sink into the lower chain portion 10a when the binding arm 4 is tilted, and is inserted into the lower chain portion 10a when the binding arm is raised.
It is said to have a shape that extends in the direction of escape. The weight part 111) is attached to the engaging claw 11 with the bin 22' as a fulcrum and the first
In Fig. 4, a biasing force is applied in the clockwise direction, and the rotation in the clockwise direction due to this force is caused by the rotation of the claw part 1.
1a is wedged into the lower chain portion 10a to stop its rotation. The roller 23 is engaged with a peripheral wall 12a of a guide hole 12, which will be described later, so that the roller 23 is guided through the 12 guide holes formed by the peripheral wall 12a without rotating. A guide hole 12 and a regulating member 13 are integrally formed in the guide plate 14. 5. The guide hole 12 is connected to the roller 23 in relation to the raising 11 movement of the binding arm 4.
The former is 157%il+l-, and based on that, the claw part 11

aFt 1st
In Fig. 4, the direction is to return to the right. The regulating part side 13' extends in the reciprocating direction of the roller 23, starting from the upper side of the lower part 1 (la), and its length is approximately the same as the length of the guide hole 12. This regulating portion 4'1113 is a lower part of the engaging claw 110: [-] part 10a.
It has a function of regulating the displacement of the lower chain portion 10a in the -L direction caused by biting into the lower chain portion 10a. Incidentally, the regulating portion side 13 may be of the type 11 type, which is pivotally supported by the bottle 22, as shown in FIG.

24.25 is an engagement claw release bottle. The engagement claw release pin 24 is provided in a reciprocating region of the claw portion 11a and at a position where the engagement claw 11 is released from the lower chain portion 10a as shown in FIG. 11 when the binding arm 4 is raised. There is. The engagement claw release pin 25 is configured such that the engagement claw 11 is released from the lower chain portion 10a after the spring end of the binding tape 8 wound around the object to be bound is crimped in the reciprocating region of the weight portion 11b. It is located in a position where Therefore, the engagement claw release pin 25 releases the engagement claw 11 from biting into the lower chain portion 1 [1a, and first, the tension of the binding tape 8 caused by unwinding the binding tape 8 is cut off. The cut end of the binding tape 8 held by a tape holding device (not shown) will not come off by -1°.The engagement claw release pin 25 should be rotated when the attachment part 25a to the frame 2 is rotated. Therefore, the contact position between the weight portion 11b and the engagement claw release pin 25 can be adjusted by the eccentric bale.

Next, the action will be explained and explained.

FIG. 1 shows the binding arm 4 in an upright state, in which the engagement claw 11 is in contact with the engagement claw release pin 24 and rotated in the opposite direction using the pin 22 as a fulcrum. , claw portion 11a
is released from the lower chain 10a. In this state, when the binding tape 8 is pulled out by applying it to the front part of the binding tape for the object to be bound (not shown), the tape reel 8 The rotation of the sprocket 1B is transmitted to the sprocket 18 by the shaft 6.The rotation of the sprocket 1B is transmitted to the sprocket 17 via the chain 10.
1. The chain 1o rotates smoothly between the sprockets 18 and 17.

Therefore, even if a one-way clutch is not specially provided, the binding tape 8 can be pulled out smoothly.

After that, the binding arms 4 are placed on a cutting table (not shown) for binding objects.
When the binding arm 4 is tilted, the connecting rod 19 is rotated in the open direction in the figure, using the binding arms 4 and the three shafts as fulcrums. The movement of the connecting rod 19 moves and the roller 26χ>j engages with the peripheral wall 12a of the guide hole 12.
Rotate the rod 2o to the left in Figure 1 and move it.

When the roller 23 moves to the left in FIG.
is separated from the engagement claw release pin 24, and the engagement claw 11 is rotated in the direction d1 in the figure with the pin 22 supported by the weight portion 11b, and the claw portion 11a is rotated in the direction d1 in the figure.
It sinks into 0a. In that case, the regulating member 13 is provided on the upper side of the lower chain portion 10a in FIG.
The lower chain part 10a is prevented from escaping in the -L direction due to the engagement of the engagement claw into the lower chain part 10a. In the biting state, the engaging pawl 11 moves to the left in FIG. 1, and a rotational force that moves the lower chain part 10a to the left is applied to the lower chain part 10a. Therefore, the chain 10 is rotated in the 1st direction (rotated in one direction).
The rotation is transmitted to the Cheegle lure by the shaft 6, and the Cheeley lure rewinds the tied tube 8.

Due to the tilting movement of the binding arm 4, a crimping plate (not shown) provided on the binding arm 4 and a tape holding device (not shown) cooperate to close the end of the 180th roll of the binding team that wraps the object to be bound. After crimping, the weight part 11b comes into contact with the engagement claw release pin 25 and rotates in the four directions in the figure, and the C1 claw part 11a is released from the lower chain part 10a. Therefore, by unwinding the binding member 180, there is no need to apply more tension to the binding tape 8 than before (this prevents the cut end of the binding tape 8 from detaching from the tape holding device A1. The binding tape 8 is cut by a cutting mechanism (not shown) provided on the arm 4.

The binding tape 8 was cut and the four binding arms were ordered to stand up.
The roller 23 is moved by the connecting rods 19 and 20 to the right in the figure without applying a rotational force 7 to the chain part 10a (and in a state where the biting into the chain part 11a is released).

Therefore, the chain 10 is prevented from being rotated, and the tape reel 7 is not rotated. Therefore, when the binding arm 4 is raised and moved, the binding tape 8 does not slacken. When the binding arm 4 is in the upright state, the engagement claw 11 comes into contact with the engagement claw release pin 24 and is rotated counterclockwise in FIG. , the lower chain portion 10a is released from the bite and stops. This completes the binding of the items to be bound.

Next, other embodiments of the present invention will be described below.

One end of the connecting rod 19 is rotatably supported. Also,
A cam 29 is provided which is mounted on the shaft 6 at one end and fixed by a fixture 28 at the other end. The hook piece 27 is rotated counterclockwise in the figure using the pin 26v as a fulcrum by a spring roller 0 whose one end is locked to a pin 27a provided on the hook piece 27 and the other end is locked to the shaft 6. Therefore, the engaging surface 27b of the hook piece 27 and the cam surface 29a of the cam 29 are in contact with each other. Due to this, the hook piece 27 is guided according to the shape of the cam surface 29a in relation to the raising and lowering of the binding arm 4. That is, from the time when the binding arm 4 is raised, the engaging claw 11
(Until the insertion is released into the lower chain part 10a, the pin 19a provided on the connecting rod 19 is engaged by the hook 27, and the connecting rod 19 moves clockwise in the figure with the shaft 3 as a fulcrum. The movement of the connecting rod 19 is linked to the engaging pawl 11 via the connecting rod 20, and the engaging pawl 11 is moved to the left in the figure. The lower chain portion 10a of the engaging pawl 11 to (
When the IW is removed, the hook 27 says,
In association with the tilting movement of the binding arm, the hook piece 27 is lifted upward and swung clockwise by the cam surface 29a.
The engagement with the bottle 19a is released, and the engagement claw 11 automatically returns to the position when the binding arm 4 is in the upright state due to the weight of the connecting rod 19. Thereafter, after cutting the binding tape 8 and returning the four binding arms to the upright state, the hook 27 engages with the bottle 19.

FIG. 6 shows a third embodiment, in which the left end portion of the guide hole 12 in the figure is tilted downward to the left, and the binding arm 4 is in a predetermined tilted state, that is, the binding arm 4 is in a predetermined tilted state. A crimp plate (not shown) provided on the arm 4 and a tape holding device (not shown)

1a to the chain portion 10a. In the case of the embodiment 1.-,
The lower chain part 10a is made up of Freno 2 and guide plate 14.
To remove the engine 10, remove the guide plates 14, and then pull the engine 10 toward the front in the figure using the sprockets 17 and 1.8. Bye.

FIG. 7 shows the fourth embodiment, which is not shown, and this embodiment has a structure in which the upper chain part 10b of the chain 10 is fitted with the engaging claws 11 associated with the binding arm 4 from above. The part 10b is provided with a rotating part in seven directions for rewinding the tape. To explain more specifically, one end of the connecting rod 1 is connected to the bottle 3 provided on the binding arm 4.
At the other end, a bottle 33 is fixed through one shell of the continuous rod.
