As shown in Japanese Patent Publication No. 234, etc., the knotter-billing type is well known. In this binding device, the binding string supplied from the needle is knotted by pinching it with a rotating knot building, and the rotating string holder holds the end of the string and cuts the string. The building consists of a fixed claw and a movable claw that swings open and close relative to it. At the time of knotting, the new string part supplied by the needle and the old string part already held by the string holder are picked up. It is configured to knot.

As shown in FIG. 15, the tip of the movable claw 10B is fixed to the fixed claw 10B.
By closing and engaging the notch 13 formed at the tip of A, the string is prevented from slipping out from the tips of both the claws 10A and 10B that are closed.

ることを目的としている。In the above-mentioned binding device, the string clamped between the movable claw and the fixed claw moves to the toe side in the knot forming step in the latter half of the knotting operation. In the case of a thick hemp string, the string that has moved to the toe side is strongly pinched in the narrowing space between the movable claw and the fixed claw, and sometimes the string breaks. Of course, it is possible to avoid string breakage due to strong pinching by setting a large interval size of the sandwiching space, but if you do this, when using thin hemp string or synthetic resin string, The string is likely to move in the longitudinal direction of the claw, making it difficult to bind with a good tightness, and it is not possible to unnecessarily set a large spacing between the sandwiching spaces. The present invention has been made paying attention to such a point, and by reasonably improving the knot building, it is possible to perform a tight binding when a thin string is used. However, it is an object of the present invention to prevent string breakage when a thick string is used.

In the above, the end portion of the string a that was initially clamped is separated from the string holder 11, and the string a on the needle 9 side is clamped by the string hooking claw 16b of the string holder 11 in the string holder 11, and the string holder 11 is newly attached. The knotted building 10 side of the held string a is cut by the cutter 16c of the string holder 11.
Then, the discharge arm 12 is actuated to push out the bound grain culms B in the right direction in the figure as shown in FIG. 7, and as the grain culm B moves, the cord a on the grain culm B side is connected to the cord guide hole 20a. It is pulled rightward in the figure along the inclined stepped portion 20c of FIG. 1, and accordingly, the loop a1 of the string a wound around both the fixed claw 10A and the movable claw 10B is pulled out from the knot building 10. Will be issued.

Even if it is pulled out from B, the holding cord a2 (see FIG. 8) held between the fixed claw 10A and the movable claw 10B is fixed to the fixed claw 1
Since it remains between 0A and the movable claw 10B, the loop a of the string a
When 1 is pulled out from the knot building 10, the holding cord a2 is inserted into the loop a1 of the cord a. Then, when the grain culm B is further pushed to the right in the figure, the knot m is formed at the portion of the ring a1, and as shown in FIG. 8, the holding cord a2 also comes out of the knot building 10 at the end. The bundling operation for one cycle is completed.

The state in which the movable claw 10B is closing and moving to pick up the two strings a from 1 is shown. In this state, the movable claw 10 in which the two strings a from the string holder 11 are closed and moved.
It touches B at a point q and is lifted up while being handled, whereby it is drawn toward the fixed claw 10A. Then, in the closed state of the movable claw 10B shown in FIG. 5, the string a is clamped by the projecting portion 15 and the string clamping surface fb on the movable claw 10B side, and the clamping position of the winding cord part a ′ is held. For the first time, the wrapping cord portion a ′ is pulled by the operation of the discharging arm 12 shown in FIG. 7.
