[Detailed description of the invention] (a) Industrial application field The purpose of the invention is a technology for facilitating the threading of a string through a grain culm binding part such as a binder.

(b) Prior art When threading a binder, etc., the string is passed through a string brake device, a slack removal rod, a string guide rod, etc.
Ultimately, it is necessary to pass the needle through the string hole, which is a complicated procedure, and the work must be done below the binder's conveyance guide plate, making it a cumbersome task for the operator. It is.

Conventional techniques for simplifying the string threading work include:
Techniques such as those disclosed in Japanese Patent Application Laid-Open No. 104913/1983 are known. However, in this conventional technique, since the flexible rod through which the string is passed is formed by a plate spring, there is a problem in that even if the plate spring is pushed out by the feeding device, a sufficient force for conveying the binding string cannot be obtained. It was hot.

In addition, the V-shaped locking groove provided at the tip of the plate spring was unable to sufficiently lock the binding cord, causing the problem that the flexible lever and the binding cord would come off midway through. be.

(c) Problems to be solved by the invention The present invention ultimately allows the string to be passed through the string hole of the needle mechanically using a flexible rod without the need for an operator to guide the string. That is.

In a mechanical string threading device using a flexible string threading rod having such a configuration, when the flexible string threading rod and the binding string are connected and passed through the guide pipe 1, sufficient conveying force of the string is applied to the string. It is constructed so that it can be obtained by a flexible threading rod, and is constructed so that it will not come off when the binding cord is locked to the tip of the flexible string threading rod.

(d) Means for solving the problem The purpose of the present invention is as described above. Next, the configuration for achieving the purpose will be explained.

By meshing the teeth of the flexible rod letting-out wheel 6 with the string-passing flexible rod 4 around which the screw protrusion is wrapped, and manually operating the flexible rod letting-out wheel 6 with the string-passing handle 3, the string-passing flexible rod is inserted. 4 is provided, and the end of the binding string M of the binding string tube A stored in the string case 32 is provided at the tip of the string passing flexible rod 4 that is paid out by the feeding device K.

A lever connecting portion 3a for operating the recoil device 24 projects in a direction perpendicular to the operating handle 13. A string passing handle 3 is fixed to the end of the lever connecting portion 3a.

By pulling the string passing handle 3 in a direction perpendicular to the operating handle 13, the recoil shaft 15 rotates and the flexible rod feeding wheel 6 is driven. Further, when the operator releases the string threading handle 3, the unwinding force of the recoil spring in the recoil device 24 causes the lever connecting portion 3a to be connected to the string threading handle 3.
is rewound.

By rotating the flexible rod drawing-out wheel 6, the string-passing flexible rod 4 is fed out. A guide roller 8 is disposed close to the cylinder of the flexible rod feeding wheel 6, and the flexible rod 4 is engaged with the string by both the flexible rod feeding wheel 6 and the guide roller 8. ,
It is something that is brought out.

In this embodiment, the string passing flexible rod 4 has a screw protrusion wrapped around the outer periphery of the wire, and the teeth of the flexible rod feeding wheel 6, which is also configured in a gear shape, mesh with the screw protrusion. , it is configured to be played out.

The string passing flexible rod 4 is connected to this flexible rod drawing-out wheel body 6.
The rotation of the storage pipe 2 causes the binding cord M to be hooked and unwound from the storage pipe 2 to the guide pipe 1, and it is flexible because it passes through the inside of the guide pipe 1 which is arranged in a winding manner. It is necessary to have the following. Therefore, it is sufficient that the string passing flexible rod 4 is rigid enough to withstand the resistance of the binding string M and has the property of bending along the bending of the guide pipe 1.

The storage pipe 2 is divided into front and rear parts at the engagement part with the flexible rod feeding wheel 6, and the rear storage pipe 2b completely serves to store the flexible rod 4 through which the string is passed, but the front storage pipe 2b The pipe 2a has a setting groove 2c for setting the binding string M and the string locking protrusion 5 in the shape of a cutout groove. The set state of the binding string M in the setting groove 2c is as shown in FIG.
