This intermediate spur gear is connected to the output shaft side spur gear t! It is installed so that it always meshes with l. Also, the intermediate spur gear!
When the seesaw member Otsu 7 is moving in the direction of arrow P (left rotation direction in Fig. 73) as shown in Fig. 73, it is separated from the first shaft side spur gear Otsu and is not tied together. It does not act on the wire twisting device E side, and on the contrary, the seesaw member O 7 is
As shown in the figure, when moving in the direction of arrow Q (clockwise rotation direction in Figure 711), it meshes with the spur gear 6 on the seventh shaft side to reverse the binding wire twisting device E. This seesaw member O7 is the anti-intermediate spur gear O!
By pulling the side arm part O 7b upward with the spring O r, it is constantly biased in the direction of arrow P (Fig. 13), and also in the direction of arrow BIQ (Fig. W/I1) by the suppression wave fltK described below.

The gripping device fixed position stationary device G stops the claw member 3.2 of the wire binding gripping device C at a position where it can grasp the wire binding arc portion 10c to be wound next, and also changes the reverse drive state of the wire binding twisting device E. The gripping device fixed position fixing device G has the action of separating the gripping device from the shaft 102 on the side of the twisting device reversing device MF.
A contact member 7.20 is attached to the tip of the cable, which protrudes in the same direction as the wire binding device faC side. This contact member 7
．． 20 is positioned at a position corresponding to the pawl 3.2b of the pawl member 32 when the wire binding gripping device C is retracted the most, and the twisting device reversing device F operates to remove the pawl 3.2b of the pawl member 32.
When the claw 32b is rotated to a position where it can grasp the binding wire arc portion 10a to be wound next, the claw 32b hits the member/20.
It acts to push up the corresponding part U 20, thereby rotating the shaft 102 in the clockwise rotation direction in FIG. 1g, and stopping the operation of the twisting bag opening reversing device fliF.

Therefore, the rotation of the binding wire gripping device C is stopped when the operation of the twisting device reversing device F is stopped, and the claw 32 of the claw member 32 is stopped.
b also comes to rest at a predetermined position.

In addition, this binding machine 1 can be configured such that the motor μ is stopped when the gripping device fixing device G is activated and the twisting device reversing device F is stopped. For example, a motor switch may be provided at a suitable location in the binding machine in addition to the starting switch 3, and the contacts of the motor switch will be opened when the gripping device fixed position stationary device G is activated and the paperback device reversing device F is stopped. It is better to do this.

Next, we will explain how to use the shown binding machine and its functions with reference to the operation diagram of each device shown in Figure 7. This actual N4B shows a 5-go binding machine for binding two pieces of iron.

As it approaches, the shaft member 3/ is first advanced by the third cam plate 0 as shown in the second figure, and after a short rotation, the chuck member 33 is advanced by the seventh cam plate 0.

Approximately in synchronization with the movement of the chuck member 33, the third cam plate is moved forward and the driving latch/2 is switched to the neutral position as shown in FIG. 7, and the cable feeding device B
stops.

Near the end of the forward movement of the chuck member 33, the chuck member 33 closes the claw member 32, and as shown in FIG.
When the shaft member 3/ moves forward, the operating rod 9 of the wire binding cutting device also moves forward, and the wire gripping device C holds the wire binding wire PI! Part III Cut the binding wire almost in synchronization with grasping the IQ tortoise.Next, as shown in Fig.
The binding wire twisting device is activated by WW on the side, and binding II

In addition, the clutch portion 53 between the first shaft j and the second shaft s5 of the binding wire twisting device ME is attached to the binding wire arc portion/Oe B 4. S Otsu slips and I can't cry any more. When the torsional action is carried out for a predetermined period of time, the drive switching clutch/2 is shifted to neutral again and the torsional action is stopped. Immediately after that, the chuck part #33 retreats and the pressing force against the claw member 32 is released, and the claw member 3.2 is possible. By the way, when the binding wire twisting portion 10b firmly ties the claw 3.2b of the claw member 32, the spring 3B
Even if used in the same direction, the claw member 32 will not open easily. Therefore, when the chuck member retreats, that is, when the push rod O/ on the first cam plate go retreats, the cam member 10/ operates the upward lever 103 to activate the twisting device reversing device F, and the binding is performed. The swinging device E is reversed (in the direction of arrow R). Then, the binding that secures the claws 32b of the claw member 32! ! i! The fastening portion of the torsion portion 10h is loosened, and the claw portion 32 is reliably WFIHed by the action of the spring 3B. Next is the cable twisting device? By reversing lE, the claw of the claw member, ? ! b is am-qrh
': As shown in (W/4' diagram), it collides with the lower surface of the contact member 7.20 and pushes up the corresponding part 8120, stops the paper device reversing device F, and the claw 32b of the claw member is wound next. It acts to hold the binding wire arc portion 10tz stationary at a predetermined position so that it can be grasped.

At this time, the Motag is immediately stopped and the entire reinforcing bar binding process is completed.

In addition, the binding wire IO is a mobile case! The windings t can be taken out one after another, and if the winding t is used up, a new winding t can be replenished. In addition, at sites where commercial power sources can be used, commercial power sources can be used simply by connecting the outlet.

Next, to explain the present invention in detail, when the tying machine of the present invention is used, a series of operations from winding the tying wire around the object to be bound such as reinforcing bars to twisting and tightening the 0-twisted tying wire are performed. The tying machine of the present invention can perform the tying work completely self-excited, improving the efficiency of the tying work and greatly reducing the fatigue of the worker. Since the cable twisting device E can be rotated in the opposite direction, the cable gripping device C can be reliably moved from the cable twisting portion /Qb. Because of this, the wire tying gripping device C- can always be kept stationary in a position where it can grasp the next tying wire arc portion 10Φ, which has the advantage of facilitating the next tying operation. be.
