Next, the structure of the essential parts of the automatic stringing device of the present invention will be described with reference to FIGS. 3, 4, and 5.

A support plate 14 is fixedly mounted on the operation handle 13, and a recoil device 24 is arranged on the lower surface of the support plate 14. A recoil wire 3a for operating the recoil device 24 is projected in a direction perpendicular to the operation handle 13. A string threading handle 3 is fixed to the end of the recoil wire 3a.

By pulling the stringing operation handle 3 in a direction perpendicular to the operation handle 13, the recoil shaft 15 is rotated and the flexible rod feeding wheel 6 is driven. When the operator releases the stringing operation handle 3, the recoil wire 3a and the stringing operation handle 3 are unwound by the unwinding force of the recoil spring in the recoil device 24.

The flexible rod 4 is fed out by the rotation of the flexible rod feeding wheel 6. A guide roller 8 is arranged close to the circumference of the flexible rod feeding wheel body 6, and the stringing flexible rod 4 is engaged by both the flexible rod feeding wheel body 6 and the guide roller 8. It is something that is paid out.

In the present embodiment, the stringable flexible rod 4 has a structure in which a screw protrusion is wound around the outer periphery of the wire, and the tooth portion of the flexible rod feeding wheel body 6 also formed in a gear shape meshes with the screw protrusion. , So that it can be extended.

The stringing flexible rod 4 has a function of being pulled out by hooking the binding cord M from the storage pipe 2 toward the guide pipe 1 by the rotation of the flexible rod feeding ring 6, and is also arranged in a meandering manner. It is necessary to have flexibility in order to pass through the inside of 1 while bending.
Therefore, the stringable flexible rod 4 may be any rod as long as it has a rigidity that is not defeated by the resistance of the binding cord M, and has a property of bending along the bending of the guide pipe 1.

In this embodiment, a screw projection is attached to the outer circumference of the wire, but a synthetic resin rod may be fed out by friction, or a toothed portion may be provided to form a rack. Further, the flexible rod feeding wheel body 6 may be a synthetic resin gear or a friction body.

The storage pipe 2 is divided into front and rear at an engaging portion with the flexible rod feeding wheel body 6, and the rear storage pipe 2b serves to store the flexible rod 4 completely through the string, but the front storage In the pipe 2a, the set groove 2c for setting the binding string M and the string locking projection 5 is formed in a notched groove shape. The set groove
The set state of the binding cord M in 2c is configured as shown in FIG. As shown in FIG. 2, the string retaining projection 5 fixedly provided at the tip of the flexible stringing rod 4 is the front storage pipe when the flexible stringing rod 4 is rewound by the recoil device 24.
It is stored in the rear part of the set groove 2c in the 2a.

A string guide plate 23 is arranged at the front end of the support plate 14, and the string guide plate 23 guides the binding string M drawn from the binding string tube A of the string case 32, and the binding string M is the string guide plate. It passes through the guide holes 23a of 23 and is inserted into the guide pipe 1. The guide hole 23a is provided with an arcuate guide surface in the pulling-out direction so that the cord is not hooked.

Before the binding string M is threaded through the string hole 18a of the needle 18, it is necessary to pass through the string brake device 10 and the slack removing rod 7 in order to eliminate a binding error due to slack, and this operation is also a string threading operation handle. It is configured so that it can be automatically performed by pulling 3.

That is, the string brake device 10 and the brake roller 12 are arranged in a pressed state by the braking spring 19 at a position immediately before exiting the guide hole 23a of the string guide plate 23, and the string brake device 10 and the brake roller 12 bind the string together. The frictional braking force acts when M is pressed. Reference numeral 20 is a braking force adjusting handle of the braking spring 19.

Next, the configuration of the slack removing rod 7 will be described. The slack removing rod 7 has a structure in which the front and rear ends of the binding cord M are locked and the central portion thereof is pulled by a ring-shaped rod having spring force. In the present invention, the guide pipe 1 is rear portion. The guide pipe 1b and the front guide pipe 1a are divided into two parts, and the binding cord M is taken out in the direction of the slack removing rod 7 from the dividing part.

Therefore, it is necessary to arrange the ring portion of the slack removal rod 7 at a position separated from the guide pipe 1, and it is difficult to pass the slack removal rod 7 through the flexible rod 4.

Therefore, when stringing, it is necessary to arrange the slack removing rod 7 concentrically with the guide pipe 1.

Further, it is necessary that the stringing flexible rod 4 and the string locking projection 5 at the tip thereof pass between the string braking device 10 and the brake roller 12, but cannot pass in the braking state. Therefore, a device for releasing the string brake device 10 at the time of threading the string is provided. At the same time that the cord brake device 10 is released, when the slack removing rod 7 is threaded, a device for rotating the guide pipe 1 to the concentric position is arranged.

That is, the string passing lever 9 has this function.
The string passing lever 9 is an arm 16 pivotally supported on the recoil shaft 15.
The arm 16 is rotated by rotating the string-placing lever 9, and the set arm 17 engaged with the arm 16 is rotated. The set arm 17 is fixed to the brake roller shaft 22 of the brake roller 12, and the brake release cam 21 is fixed to the upper end of the brake roller shaft 22. It moves by turning to open the upper end of the string brake device 10 pivotally supported at the lower end. The brake release cam 21 allows the string locking projection 5 and the string-placing flexible rod 4 to pass through the space where the string brake device 10 is opened.

At the same time, a winding spring portion that constitutes the base of the slack eliminating rod 7 is fixedly mounted on the brake roller shaft 22, and the slack eliminating rod 7 is rotated by the string threading arrangement lever 9 so as to move to the guide pipe 1 as shown in FIG. It is rotated to the concentric position. The slack removal rod stopper 11 has a side surface of the guide pipe 1 opposite to the slack removal rod 7 so that the slack removal rod 7 does not go over the concentric position of the guide pipe 1 by the rotation of the string passing lever 9. It is located in.

With this configuration, when threading, the threading arrangement lever 9 is first rotated to bring the threading state as shown in FIG.
With the binding cord M set in the position of the set groove 2c in the figure,
By pulling the stringing operation handle 3, the stringing flexible rod 4 and the string locking protrusion 5 are pushed out from the storage pipe 2,
The binding string M is hooked at the tip, passes through the string braking device 10 in the opened state, passes through the slack removing rod 7 arranged at a concentric position, is guided in the guide pipe 1, and is needle.
The protruding state of the flexible rod 4 through which the string passes is stopped by the stopper 4a at a position where the string 4 extends in a direction substantially perpendicular to the tip of the string 18 and passes through the string hole 18a. The operator takes out the binding cord M that has passed through the cord hole 18a, hooks it in the state shown in FIG. 5, and sets it.

FIG. 5 shows a plan view of the binding device portion, and the binding string M is a positioning piece fixed to the right end of the knot frame 27.
The position is accurately determined by engaging with 25, and the end is hooked and stopped by an engaging piece 26 provided on the crank arm portion of the discharge rod 29 in the stored state. When the binding clutch door 28 is pulled in this state and the clutch is put in and the binding action is performed in the empty state, the binding cord M is moved by the needle 18 to the knot building 30 and the knot holder 31 portion in the knot frame 27. The M is guided to create a state of being held by the knot holder 31. After that, the end of the binding string M cut by the string cutting blade is pulled by the rotation of the release rod 29, so that the string threading operation is completed by removing it from the locking piece 26 and removing it. 33
Is a packer.

(F) Effects of the Invention Since the present invention is configured as described above, it has the following effects.

First, by arranging the automatic stringing device as in the present invention on the discharge side of the handle base, the stringing operation handle 3 in a pulled state is maintained with the left hand, and the binding string M after stringing with the right hand. Since the tip of the can be grasped, the string threading operation can be performed by one person.

Secondly, since the position of the flexible rod feeding device P and the position of the binding string M after threading are close to each other, the operator can thread the binder on the side of the machine with almost no movement. Therefore, the operation can be simplified.

Thirdly, pull out the end of the binding cord M from the binding cord tube A,
It is possible to pass the binding string M through the string braking device 10 and the slack removing rod 7 by simply placing the stringing flexible rod 4 on the set groove portion and then unwinding the stringing flexible rod 4 by the stringing operation handle 3. Therefore, it is possible to automatically pass under the conveyance guide plate, which is the most difficult to thread, by the guide pipe.

Fourthly, after the string is passed, the flexible stringing rod and the binding string can be removed by allowing the operator to grasp the binding string with the right hand while holding the stringing operation handle with one hand. It became.

Fifth, since the automatic stringing device is arranged on the side of the string case on the discharge side of the bound grain culm, and there is no transport guide plate in that part,
The binding state of the binding cord and the flexible rod through which the cord is passed can be reliably performed at a position where the operator can easily see.
