When the tip of No. 1 is supplied to a position intersecting the wire 11 at a position facing between the projecting pieces 44, 44, the air motor 35 is stopped and the supply of the wire 11 is stopped (Fig. 12 (c). )reference). When the drawing of the wire 11 from the wire reel 12 is stopped, the leaf spring 28 prevents the reel 12 from rotating due to inertia, and the weight 29 prevents the winding state of the wire 11 from being disturbed. The wire is held in a state where it can be smoothly pulled out next time. The supply length of the wire 11 is equal to that of the air motor 35.
It is preset by the forward rotation angle of.

When the air motor 35 is stopped, pressurized air is supplied to the second passage 53 of the twist device 21,
The air flows from the second passage 53 to the relay space 54 to the supply passage 64.
Is supplied to the first space 56 via. When the pressure in the first space 56 becomes larger than the elastic force of the compression spring 63, the opening / closing member 62 advances to close the clamping jaws 58b, 58b, as shown in FIG. As a result, the intersection of the wires 11 is clamped and the guide 4
The wire 11 facing the second side is cut by the cutter 66. At this time, the pressurized air is also supplied to the second space 57 through the auxiliary passage 70 and the through hole 68, so that the first space 56 is released.
However, since the compression spring 69 inserted in the storage portion 67 is set to the above-mentioned elasticity, the compression spring 69 does not compress the compression spring 69 and holds the shaft portion 59b of the positioning pin 59 as a holding member. It is held in a state of projecting outward of 55 (see FIG. 8).

Here, when the clamping jaws 58b, 58b rotate with the cut end of the wire 11 protruding from the end of the guide body 42, the jaw 58b comes into contact with the cut end of the wire 11. There is a possibility that the wire may be bent and the next wire supply may be hindered. Therefore, at the timing when the wire 11 is cut by the clamping jaws 58b, 58b, the air motor 35 slightly reverses and the pair of pinch rollers 33, 34 reaches the position where the cut end of the wire 11 faces the guide body 42. It is designed to pull back. This can prevent the cut end portion of the wire 11 from being bent by the clapping jaw 58b. When the reverse rotation of the air motor 35 is completed, the clutch is released and the air cylinder 3 of the brake 37 is released.
1 is urged to bring the brake shoe 40 into contact with the first pinch roller 33 to prevent the roller 33 from rotating. Then, the air motor 35 rotates in the reverse rotation direction and returns to the origin to stop.

At the time when the clamping and cutting of the wire 11 is completed by the clamping jaws 58b, 58b, the operator moves the main body 15 upward to a position where the head 73a of the bolt 73 of the positioning device 80 contacts the bracket 72. Pull up. As a result, as shown in FIG. 13 (a), the wire 11 wound around the intersection of the vertical streak 16 and the horizontal streak 17 has an elliptical shape, and the binding by the subsequent twisting work can be ensured.

After the wire 11 is clamped by the clamping jaws 58b, 58b, the first space 56
The air supplied to the through hole 68 passes through the auxiliary passage 70.
And supplied to the second space 57. And the second space 57
1 becomes larger than the elastic force of the compression spring 69,
As shown in 0, the positioning pin 59 is retracted to move the shaft 59b.
The leading end of the holding member 55 sinks into the through hole 68, and the rotation of the holding member 55 is allowed. Next, pressurized air is supplied to the first passage 50, and the rotation drive mechanism 49 rotates. This rotation is transmitted to the holding member 55 via the planetary gear mechanism 51 and the clutch shaft 52, and the holding member 55 is rotated clockwise (in FIG. 10). As a result, as shown in FIG. 13B, the clamping jaws 58b, 58 of the pliers 58 are
The wire 11 clamped at b is twisted, and the intersection of the vertical line 16 and the horizontal line 17 is bound. That is, the operator merely exposes the intersection of the vertical stripes 16 and the horizontal stripes 17 to the opening 81 defined by the pair of guide shells 18 and 19, and thereafter the wire 1 is formed based on the required sequence.
1, feeding, clamping and cutting of wire 11, wire 1
Twisting 1 is done automatically and does not require much labor. Further, until the clamping of the wire 11 by the clamping jaws 58b, 58b is completed, the rotation of the holding member 55 is blocked by the positioning pin 59, so that the rotation of the holding member 55 can be performed without clamping the wire 11 by both jaws 58b, 58b. It may prevent it from starting. The number of twists of the wire 11 is set by the supply time of the pressure air supplied to the first passage 50.

Here, when the wire 11 is twisted, the horizontal streak 17 is caused by the decrease in the gap between the cross section of the vertical streak 16 and the horizontal streak 17 and the ring-shaped wire 11.
The relative distance between the wire and the open end of the wire 11 becomes short. That is, when the operator holds the main body 15 at a position in which the head 73a of the bolt 73 of the positioning device 80 is pulled up to a position where the head 73a of the bolt 73 contacts the bracket 72, the wire 11 is accompanied by the twist. There is a possibility that the clamp position of is pulled toward the lateral streak 17 and is cut. Therefore, it is necessary to bring the main body 15 closer to the lateral streak 17 with the twist of the wire 11. However, if the body 15 is brought closer than necessary, the wire 11 loosens and reliable binding cannot be performed. However, in the embodiment, since the regulating plate 74 is pressed against the horizontal bar 17 under the elastic force of the compression spring 76, the wire 11 wound around the intersection of the vertical bar 16 and the horizontal bar 17 is always in tension. Is held. Therefore, if the operator holds the main body 15 lightly, the main body 1
The wire 5 gradually approaches the horizontal bar 17 against the elasticity of the compression spring 76 with the twist of the wire 11, and
Can be twisted in a state in which it is always taut, and as a result, reliable binding is achieved.

When the twist of the wire 11 is completed,
The supply of the compressed air to the first passage 50 and the second passage 53 is stopped, the shaft 59b of the positioning pin 59 is projected from the holding member 55 by the elastic force of the compression spring 69, and the opening / closing member 62 is compressed. The wire 1 is moved backward by the elastic force of 63 and by the clamping jaws 58b, 58b.
The pinching of 1 is released. Then, the shaft portion 59b of the positioning pin 59 is pressed by the elastic force of the compression spring 69 in the direction of protruding from the holding member 55. When the shaft portion 59b faces the eccentric cutout portion 71a by the rotation of the holding member 55, the shaft portion 59b gradually projects from the holding member 55 along the inner peripheral surface of the cutout portion 71a. Then, the shaft portion 59b becomes the step portion 71.
The rotation of the holding member 55 is stopped at the position where it abuts against b.
At this time, as shown in FIG. 3, the pair of clamping jaws 58b, 58b of the pliers 58, with the cutter 66 oriented toward the guide body 42, intersects the wire 11 fed through the guide body 42. The positioning is stopped at a position where it can be clamped. In this state, the operator lifts the main body 15 upward to complete the binding at the intersection of the vertical stripes 16 and the horizontal stripes 17, as shown in FIG. 13 (c).

The inner diameter of the wire 11 which is supplied by the supply device 20 and is formed into a ring shape is equal to the inner diameter of the guide shell 1.
Since it is set by the inner peripheral dimension of the formation portion of the guide grooves 18b and 19b of 8 and 19, the vertical stripe 16 is changed by changing the order.
There is a case where the diameters of the horizontal streak 17 and the horizontal streak 17 are changed, and the guide shells 18 and 19 having the conventional dimensions cannot be used. At this time, the guide shells 18 and 19 are replaced with those of corresponding sizes, and the supply amount of the wire 11 is adjusted, so that the vertical streaks 16 and the lateral streaks 17 of various sizes can be bound.

[0038]

As described above, according to the binding machine according to the present invention, the operator simply faces the intersection of the vertical stripes and the horizontal stripes in the opening defined between the pair of guide shells of the binding machine. Thus, the intersecting portion can be reliably bound by the wire. That is, the operator can be freed from the binding work that requires manual work and can improve work efficiency. Further, since a continuous wire is automatically cut when it is bound, a complicated work of cutting the wire into a predetermined length in advance is not necessary. Moreover, since the structure is simple and portable, the manufacturing cost can be kept low and it can be carried out without a large capital investment.

Further, since the wire reel around which the wire is wound is formed separately from the main body, the weight of the main body can be reduced. Further, since the pair of clamping jaws for clamping the wire are always stopped at the fixed positions, the wire can be reliably clamped in each binding operation. Furthermore, when the intersection of the vertical and horizontal stripes is exposed in the opening of the guide shell, the intersection can be positioned at the proper position of the opening, and the wire supplied from the feeder secures the intersection. There is an advantage that it can be surrounded by.
