The supply section 35 is fitted into the left main body 10a by a protrusion 34 provided at the front thereof, and is fixed to the left main body 10a by a pin 68.

As mentioned above, the lever 1 is inserted into the elongated hole 25 provided in the pressing body 24.
6 is inserted, and when this lever 16 swings, the pressing body 24 moves back and forth;
slides into contact with the side surface 67 of the binding tool supplying body 37 to cause the sending piece 37a at the tip of this binding tool supplying body 37 to protrude outward from the main body 10, or contacts the hook-shaped portion 37b and causes the sending piece 37a to be pushed out of the main body 10. Push it to the 10 side.

Further, the binding tool supply body 37 is provided with a feed pawl 40 and a release lever 39, and by operating the release lever 39, the connection between the feed pawl 40 and the assembly M' is released.

As shown in FIG. 6, the release lever 39 and the feed pawl 40 are supported by a leaf spring 52 fixed to the binding tool supply body 37. The release lever 39 is connected to the leaf spring 5 with respect to the feed pawl 40.
This release lever 39 is located on the side of the head 52a of the
When pressed as shown by the arrow a, the free end of the leaf spring 52 goes down, and the feed pawl 40 is pulled down toward the bottom of the binding tool supply body 37 as shown by the arrow A.

The lower surface 39b of the hole 39a provided in the release lever 39 is inclined so as not to hinder the bending of the leaf spring 52.

Therefore, by operating the release lever 39, the aggregate M' filled in the main body 10 can be removed. At this time, one of the binding tools M is left in the main body 10 for convenience in the next binding operation (see FIG. 8).

Further, as can be understood from FIG. 3, the retractable protrusion 41 is attached to the left main body 10a so that the protrusion 69 projects into the supply path of the binding tool M, and the binding tool M fed into the guide groove 29 flows backward. It acts as a stopper to prevent this from happening.

As shown in FIG. 4, locking bodies 71 are arranged on both sides of the first guide groove 29, respectively. This locking body 71 consists of a U-shaped main body 72 and a protrusion 73 that protrudes so as to cover the first guide groove 29, and is configured to prevent the binding tool M from lifting up on the lower surface 74 of the protrusion 73. There is.

This locking body 71 is connected to a recess 70 provided in the main bodies 10a and 10b.
is attached to.

This locking body 71 is arranged on the main bodies 10a, 10b so as to correspond to a position slightly rearward from the thin wall portion 1a of the binding tool M when the tip of the binding tool M reaches the leading edge of the guide groove 29.

The above-mentioned locking body 71 is not particularly limited to the above-mentioned position as long as it is at a position where the binding tool M can be folded in half.

On the other hand, as shown in FIG. 3, a guide 76 for supporting the assembly M' is provided on a cover 75 attached to the top of the main body 10, and a passage 77 through which the projection 6 of the binding tool M passes is provided in the main body 10.

Next, the operation of the binding machine having the above configuration will be explained with reference to FIGS. 8 to 10 and FIGS. 11 to 14.

Regarding the operation of M', FIG. 8 shows a state in which the cover 50 of the supply section 35 has been removed and the assembly M' has been placed on the guide surface 51.

As can be understood from FIG. 8, one of the binding tools M remains in the guide groove 29 due to the previous binding operation, and is ready for binding by the next operation of the operating lever 12.

In this state, the ring-shaped part 2 of the binding tool M is located at the front, and the head 5
is located at the rear. Further, a bending lever 61 is located behind the head 5 of the binding tool M.

As shown in FIG. 11, in this state, the object W to be bound is placed on the receiving portion 60 at the tip of the main body 10.

On the other hand, as shown in FIG.
The position is regulated so that it does not protrude from the guide groove 29. Further, the feeding claws 40 protrude between the arranged binding tools M to prepare for the next feeding.

Next, by grasping the operation lever 12, the bending lever 61 moves forward in the direction of the arrow F together with the pressing body 24, as shown in FIG. The binding tool M is fed into the tip of the main body 10. Then, the ring-shaped part 2 of the binding tool M is gripped by the stoppers 66 provided on both sides of the tip of the guide groove 29, and the binding tool M will not move forward any further.

In this way, even when the binding tool M is stopped by the stopper 66, the pressing body 24 continues to move forward, so the bending lever 6
The pin 63 provided at 1 moves in the direction of arrow P in the bending portion 65 to the end point and stops. At this time, the binding tool M is fed under the object W to be bound.

Further, as the pressing body 24 moves forward, the bending lever 61 rotates in the direction of arrow J, and the guide surface 61 rotates accordingly.
The head 5 of the binding tool M is pushed up as shown by arrow Q by a.

At this time, the thin wall portion 1a of the binding tool M is prevented from rising by the projection 73 of the locking body 71, so that the binding tool M begins to be bent in two from the thin wall portion 1a.

In addition, when the binding tool M moves forward, the protrusion 7 of the locking body 71
3 prevents it from jumping out of the guide groove 29.

On the other hand, as shown in FIG. 9, as the pressing body 24 advances, the binding tool supply board 37 rotates in the direction of the arrow R, but at this time, it is located at the leading edge of the assembly M'. The binding tool Ma is cut by the blade plate 32 and the pressing body 2 is removed as shown in FIG.
4 and moves forward on the guide surface 29b.

Note that FIG. 9 shows a state in which the binding tool Ma has advanced halfway along the guide surface 29b.

(c) Regarding the bending operation, since the pin 63 of the bending lever 61 is prevented from moving forward at the end point of the bending part 65 of the second guide groove 64, the pressing body 2
4 further moves forward, the bending lever 61 further rotates, and the head 5 side of the binding tool M is bent forward by the bending surface 61b.

The object W to be bound is held between the thick parts 1b and tb which are folded in half.

At this time, the binding tool M comes off from the protrusion 73 of the locking body 71, but the protrusion 73 of the locking body 71 once retreats to the left and right, and then immediately returns to its original state.

(d) As shown in FIG. 14, the bending lever 61 further rotates in the direction of arrow J as the pressing body 24 moves forward, and the tip 61c of the bending lever 61 closes the binding tool. The thick part 1b of the head 5 of M is further pressed, the protrusion 6 provided on the head 5 is inserted into the retaining hole 3 of the annular part 2, and the protrusion 6
a is caught on the edge portion 7 and tied together.

At this time, as shown in FIG. 10, the binding tool Ma to be bound next is located at the tip of the guide surface 29b.

(As mentioned above, the binding tool M is bound by grasping the operating lever 12 after turning 81, but after this binding operation,
When the grip on the operating lever 12 is released, the state shown in FIG. 1 is restored.

The binding tool Ma located on the guide surface 20b is the pressing body 2
4 returns to its original position, the binding tool supply board 37 rotates, and as shown in FIG.
It is laterally fed into the guide groove 29 by.

(f) Regarding taking out the aggregate M' When the bundling work is completed or when the bundling work is interrupted, the aggregate M' filled in the main body 10 may be taken out. By pushing the lever 39 with a fingertip as shown by the arrow a, the feed pawl 40 moves downward as shown by the arrow A and is disengaged from the assembly M'.

Then, the aggregate M' can be easily taken out.

Note that, as shown in FIG. 15, if the assembly M' is placed against the upper part of the main body 10 and supported by the guide 76 and the passage 77, the binding tool M will not get in the way, making the binding work easier. .

The above-mentioned locking part 71 is formed by folding the binding tool M in half.
Needless to say, it can be used in a wide range of binding machines that can connect the male and female engaging parts at the ends of the tying machine.

〔Effect of the invention〕 .

As described above, according to the present invention, the locking bodies provided on both sides of the guide groove can prevent the binding tool from lifting up while moving forward, and also prevent the binding tool from lifting up during the bending operation. When bundling objects such as those to be bound, the binding device folds in two very smoothly, and as a result, bundling errors are greatly reduced compared to conventional binding machines.
