In the present invention, a string guide body is provided so as to intersect with the plane of the agitation trajectory of the supply string by the needle, and a rotating holder provided with a locking groove for winding the string is positioned on the side closer to the plane of the trajectory. The supply string is pushed out with a string guide member away from the twenty-one dollar, and the resulting tension is used to guide it to the clamping surface of the rotary holder and to accurately lock it in the locking groove. It is characterized in that it can reliably guide the string to the string holder and wrap it in the string holder.

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a schematic plan view. In the figure, 1 is a twenty-one dollar for supplying a binding string, 2 is an arm for releasing a bundled stem culm, and the main part is a tubercle.

The twenty-one dollar 1 and the ejection arm 2 are installed in a transmission case 4 located on one side of the focusing space A, and the knot part 3 consists of a knot building 5 and a string holder 6. It is arranged on the other side of the focusing space A.

The twenty-one dollar 1 is constructed in the same manner as that installed in a conventional binding device, and when the convergence pressure of the stem culms retained and converged in the convergence space A exceeds a certain level, this convergence pressure is sensed by a focused pressure sensing mechanism (not shown);
As a result, the one-turn clutch installed inside the case 4 is activated, and the intermittent rotating shaft 7 starts rotating, and by one rotation of the crank arm γ fixed to the intermittent rotating shaft 7, the 21 dollar 1 is rotated about its fulcrum B. It is configured to reciprocate at a constant angle.

Arc-shaped racks 8 and 27 are formed on the upper side and lower surface of the twenty-one dollar 1 at appropriate angles with the fulcrum B as the center, and the twenty-one dollar passes through the focusing space A. When moving to the node 3, the racks 8 and 27
As will be described later, the knot portion 3 is configured to be driven by the bill and the string holder.

In the joint part 3, the building 5 is rotatably mounted on a fixed bracket 10 via a support shaft 9, and
A string holder 6 is provided on a bracket 10 in a constant posture.

The 21 dollar 1 is attached to the support shaft 9 at this knot 3.
When the gear is inserted, the passive gear 11 that engages with the rack 8 provided on the upper surface of the dollar 1 is loosely fitted, and the rotation in one direction of the passive gear 11 is transmitted only to the spindle 9. A clutch 12 is equipped.

This one-way rotating clutch 12 has a movable clutch piece 13 slidably attached to a support shaft 9 via a key, and a movable clutch piece 13 attached to a spring 14.
, the movable clutch piece 1 is biased toward the passive gear 11 side.
The serrated dog 15 provided on the gear 3 engages with a similar serrated dog 16 provided on the passive gear 11, and when the passive gear 11 rotates in the X direction, the opposing dogs 15 and 16 engage. power is transmitted to the support shaft 9,
Conversely, when the passive gear 11 rotates in the Y direction, the movable clutch piece 13 is moved backward against the spring 14 due to the opposing dogs 15 and 160, and the dog engagement is disengaged and the support shaft 9
The structure is such that power transmission to the machine is cut off.

In other words, the building 5 does not operate against the passive gear 110 rotations due to the forward movement of the needle 1 at the node 3, and the needle 1 does not operate.
The structure is such that the building 5 is driven by the passive gear 110 rotations accompanying the backward movement of the motor.

As shown in FIG. 4, the string holder 6 has a gear 28 that engages with the rack 27 of the twenty-one dollar 1 loosely fitted on a rotating shaft 17 that is rotatably mounted on the flaket 1σ.
8 and the rotating shaft 17 are connected through a one-way rotation clutch 29, so that the rotating shaft 17 is rotated during the return stroke of the 21 dollar 1.

24 is a spring for allowing the one-way rotation.

A rotary holder 20 is fixed to the rotary shaft 17, and a fixed holder 30 having a flat clamping surface 32 opposite to the flat supporting surface 31 is provided to also serve as a shaft rack for the rotary shaft 17,
A spring 33 is provided to elastically press the rotating holder 20 against the fixed holder 30.

36 is a position where the supply string 25 is held between the rotary holder 20 and the fixed holder 30, at a position biased to one side with respect to the plane P of the fanning locus of the 21 dollar 1 supply string.

Reference numeral 19 denotes a string guide fixed to the bracket near the rotary holder 20, and its tip extends toward the upper side of the entrance of the 11 dollar 1, and also extends from the front as shown in FIG. The curved surface extends downward from the plane P so as to intersect with the plane P including the 21 dollar 10 passing locus when seen, and extends from its tip to near the supporting surface 31 of the rotary holder 20. 21, and is configured so that the supply string 25 is guided along this curved surface 21 to the position of the clamping surface 31 of the rotary holder 20.

As shown in FIGS. 5 and 6, 34... is inclined so that it becomes deeper as it goes outward from the rotation center side of the rotation holder 30, and along the direction in which the supply string is stretched. This is a locking groove for receiving and winding the engraved string, and is configured to open in the holder peripheral surface 22.

If the locking groove 34 is provided only at one location on the rotary holder 20, it may cause installation errors such as installation of the string holder 6, engagement drive between the needle 1 and the rotary holder 20, or errors due to long-term operation. The supply string 25 is connected to the locking groove 34 by
Since a situation may occur where the supply string 25 is not always caught in the locking groove 34, it is necessary to provide this at multiple locations so that even if the above-mentioned deviation occurs, the supply string 25 will always fit into one of the locking grooves 34. It is designed to hold a person.

Furthermore, the rotary holder 20 has its string locking groove 34.
An annular groove 35 formed to cross the middle of ...
is provided around the rotation center of the holder.

Reference numeral 23 denotes a fixed knife for cutting the string extending from a part of the fixed holder 30, and is provided so as to protrude into the annular groove 35 near the final winding position of the rotary holder 20.

The discharge arm 2 is crank-coupled to the intermittent rotating shaft 7 and starts operating at the same time as the 21 dollar 1, and its tip traces a certain trajectory and comes into contact with the bundled stem culm at the discharge timing. and is configured to perform the release action.

E is the string anchoring point of the string holder 26, which is located on the cover wall of the tuberosity.

The present invention is constructed as described above, and its operation will be explained next.

FIG. 1 shows the state before the tying operation. In this state, the free end of the tying string 25 fed out from the tip of the twenty-one dollar 1 stopped at the retracted position is on both clamping surfaces of the string holder 6 at the knot. It is elastically held by the string holding part C of 3L32 by a spring 33 and crosses the rear part of the focusing space A, and is fed into the focusing space A, and the stem culm D is sequentially retained and focused.

When the amount of culm focusing becomes constant, this is sensed as focusing pressure, and the intermittent rotating shaft 7 starts rotating, and the needle 1 wraps the binding cord 25 around the focusing culm D and passes through the focusing space A to the nodule. The knotted string 25 is supplied to 3.

The passive gear 11 is activated by the actuation of the 21 dollar 1 within the node 3.
is engaged with the rack 8 and rotates, but as mentioned above, the bill 5 does not operate during the reciprocating stroke of 21 dollars 1.

When the twenty-one dollar 1 reciprocates while the building 5 is stopped, the binding string 25 fed out from the tip of the twenty-one dollar 1 passes through the string provided close to the front of the building 5. While being locked to the holder 26, it is fanned using the locking point E as a base point and a plane P that includes a movement locus of 21 dollars 1 as a fanning plane.

Then, at the intersection point between this fanning plane P and the string guide body 19 of the string holder 6, the binding string 25 passes along the string guide body 19 on the way.
The binding cord 25 is caught on the upper surface of the cord, and the binding cord 25 is caught on the upper surface of
is guided along the upper surface of the string guide body 19.

In this way, as the 21 dollar 1 advances, the supply string comes into contact with the end of the string guide 19, is pressed by its curved surface 21, and is moved between the rotating holder and the fixed holder 30 by the tension in the returning direction. The user is guided to the supporting point 36.

The supply string guided on the clamping surface 31 of the rotating holder 20 is locked in a string receiving groove 34 formed therein, and as the rotating holder 20 rotates, the string is wound up between it and the fixed holder 30. Go.

At this time, the string receiving groove 34 is inclined along the direction in which the supply string is stretched, so that the supply string can be smoothly fitted into the string receiving groove 34, and the groove 34 is sloped so that it is shallow on the rotation center side and becomes deeper toward the outer side. Therefore, as the rotating holder 20 rotates, the string causes relative displacement, and as it rotates, the string is clamped at the groove opening of the holder circumferential surface 22 from the beginning. The stem-culm-wrapping side string, which had been wrapped around the stem, is pushed out, and on the other hand, the feeding-side string is wrapped well in the center side of the shallow groove where the clamping pressure is strong, and the stem-culm wrapping is carried out in the next step after the string is cut. Strongly clamps and holds the end of the string that becomes the side string.

By the operation of the building 5 and the rotary holder 20 during the return stroke of the needle 1, a predetermined knotting action progresses, and when the rotary holder 20 rotates and reaches the final winding position, as shown in FIG. 7e. As shown in FIG. 2, the string 25 is cut by the fixed knife 23 protruding into the annular groove 35 so as to be perpendicular to the knife while its movement is restricted within the groove.

Thereafter, the bundled stem culm D is released by actuation of the release arm 2.

At this time, the 21 dollar 1 returns to its original position, leaving the end of the string for the next step in the string holder 6, and the string catches the stem culm that is being gathered again.

In summary, the tying device according to the present invention, while being locked to the string holder 26 provided near the building 50, allows the tying device to move the twenty-one dollar supply string 25 within the swinging range from the string receiving point E as the base point. To provide the string holder 6, a relatively small-diameter rotary holder 20 and a fixed holder 30 having a clamping portion 36 on one side with respect to the plane P of the agitation locus of the twenty-one dollar supply string 25 are provided, and the fixed holder 30 The rotary holder 20 is located closer to the fan locus plane P than the rotary holder 20, and a locking groove 34 is provided on the clamping surface 31 of the rotary holder 20.
It is configured to press against the fixed holder 30 side via the bullet 33, and on the upper side of the supply string 25 with respect to the clamping surface 31 of the rotary holder 20, with respect to the plane P of the supply string 25 with respect to the agitation trajectory. A string guide body 19 has a guide surface that crosses the string receiving point E and the string supply point at the tip of the 21 dollar tip and guides the feeding string point to the supporting point 36 of the rotary holder 20 and the fixed holder 30. The cord part pushed out by the cord guide 19 is guided to the clamping part 36 of the rotary holder 20 by the tension of the cord, and the locking groove 34 of the rotary holder 20 is used to guide the cord part pushed out by the cord guide 19 to the clamping part 36 of the rotary holder 20. Since it is characterized in that it is configured to be locked and rolled up between the clamping surfaces that are raised between it and the fixed holder 30, the following effects have been achieved.

That is, a string holder consisting of a fixed and rotating holder is biased to one side from the supply string fanning trajectory, the rotating holder is positioned on the trajectory side, and a locking groove for locking the string is provided in the rotating holder. A string guiding body is provided to guide the string into the locking groove of the rotary holder so as to intersect with the trajectory, and with this, tension is applied while guiding the supply string, and the tension is applied to the supply string so that it tends to return to the clamping surface side of the rotary holder. can be accurately guided to the clamping surface of the rotary holder by using the holder, and can be inserted into the locking groove provided there, and the locked string can be reliably wound into the holder and clamped. .

Moreover, since the above-mentioned feeding and winding of the supply string can be carried out with a relatively small rotating holder compared to the conventional square holder with a large rotation radius, the overall structure can be made smaller. It also has
