Description

[Detailed Description of the Invention] The present invention relates to a string threading device that can be attached to a culm binding part of a binder or the like.

That is, in the culm binding part of a binder, etc., which is configured so that the binding string led out from the string case is guided and extended from the string brake through a long string guide such as a ring or pipe to the needle of the binding device, a new binding To provide a cord that can be easily and quickly passed through a string guide part of this kind that is difficult to thread when a string is attached or the string breaks, and has a simple structure and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Fig. 1 shows a part of the binding part that is buttoned to the binder. A door 10 is installed at the rear of the passageway, and a packer and the like are installed at the other end, similar to the conventional structure.

Reference numeral 1 denotes a string case, which is attached to the rear side of the machine where it does not get in the way of reaping and tying.The string 2 pulled out from the wound string 2a loaded in the string case 1 is passed through the string brake 3 near the string case 1. The string 2 extending from the string guide section A is passed through the hole 4a of the needle 4, but the string guide section A
Same as the conventional structure, the guide ring rod 11. Consists of a string slack removing ring rod 12, a bent guide tube 13, etc., and a needle 4
The terminal end 13 of the guide tube 13 which is the terminal end of the string guide section A near the
The cord 2 led out from the hole 4a of the needle 4 is passed through the hole 4a of the needle 4 and extends toward the knot.

Reference numeral C denotes an unwinding device, which has a known structure so that when the thin string 5 is wound up by a certain length and pulled out by that amount, it can be wound in a recoil manner by an internal unwinding spring. The string 5 extending from the string is sequentially inserted from the guide ring rod 11 which is the starting end of the string guide section A near the string brake 3 to the string slack removing ring rod 12 and the guide tube 13. As shown in FIG. 1, when the string 5 is fully wound, the tip 5a of the thin string 5 is configured to extend slightly from the terminal end 13a of the guide tube 13.

The button 2a in the figure shows the knot of the string 2.

Therefore, during the spinning operation in which the binder is used, the needle 4 operates on the shell culm buttoned in the binding passage 6 in the state shown in FIG.

By the way, when attaching a new binding string or when the string breaks, attach the tip of the string 2 extending from the string brake 3 to the thin string 5 near the guide ring rod 11 as shown in FIG. When the thin string 5 is pulled out by holding the thin end 5a side of the thin braid 5, the string 2a passes through the string guide section A as the thin string 5 is pulled out from the unwinding device C. As shown in FIG. 3, when the knot 2a comes out from the terminal end 13a of the guide tube 13, the knot 2a is untied from the thin string 5, and the tip of the string 2 is
It can be set in the binding position by passing it through the hole 4a of the T-needle 4, pulling it out as shown by the imaginary line in FIG. 3, and pulling the door 10.

Note that when the knot 2a is removed from the thin string 5 and the hand is released from the thin string 5, the unwinding device C rewinds the thin string 5, and the string becomes ready to be threaded through again as shown in FIG.

In this way, the present invention provides a binder configured to guide and extend the binding string 2 led out from the string case 1 from the string brake 3 through the long string guide part A such as a ring or pipe to the needle 4 of the binding device B. , etc., and insert the thin string 5 extending from the unwinding device C from the starting end of the string guide A near the string brake 3 to the terminal end of the string guide A near the needle 4. Since the tip of the thin string 5 is configured to extend at least from the end of the string guide section A when the extending and rewinding device C is fully wound, it is easy to attach a new binding string or to prevent the string from breaking. If this occurs,
When the tip of the string 2 extending from the string brake 3 is tied to the part of the thin string 5 on the starting end side of the string guide section A and the tip side of the thin string 5 is pulled out on the needle 4 side, the string 2 cannot be threaded manually. The string can be easily and quickly passed through the difficult string guide part A, and the thin string 5 can be rewound by the unwinding device C by the amount that has been pulled out to be ready for the next string threading, and the structure is simple. It has the characteristics that it can be suitably implemented.
