Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a string supply device in a tying machine for tying stem culms.

(b) Prior Art Conventionally, it is already known to provide a guide groove into which a needle enters along the arrangement direction of the bill and holder as a knot guide for a binding machine.

(c) Problems to be solved by the invention In the known tying machine, the bill and holder were located behind the plate surface of the knot guide, so it was impossible to insert the string through the guide groove and hang it on the holder, etc. When starting the tying process, pull out a long string passed through the hole at the tip of the needle as shown in Figure 5, stretch it outside the knot guide, hold the end of the string in your hand, and operate the door while transmitting power to the tying machine. Turn on the clutch once
Then, the needle was actuated to cause the string to enter the knot guide through the guide groove, and the bill and holder were then actuated to tighten the string.

However, it is possible to accidentally start tying just by passing the string through the hole in the needle, and in such cases, tying cannot be completed, and even if the string is tightened according to the normal procedure, the needle may not be properly tied. Bill wraps the supplied string and operates, and since this operation is a blank firing, even if the sweeper operates, the string is not released by releasing the bundle, so Bill holds it and removes the wrapped string. I had to.

In addition, in the known tying machine, there is a method of starting work by tying the end of the string passed through the hole of the needle to a suitable place on the frame, but in this method, the string is not hung on the building or the holder. I couldn't tie the first bundle.

(d) Means for solving the problem In the present invention, a nodule guide is provided on the front surface of the building and the holder, and a guide groove is provided in the nodule guide along the arrangement direction of the building and the holder and into which the needle enters. In the tying machine, a transverse groove is provided on one side of the guide groove of the knot guide, and a string locking device is provided on the bundle release side of the knot guide so that the string passed through the hole of the needle runs along the outside of the knot guide. At the same time, the above-mentioned problem was solved by passing the middle part of the string through the transverse groove and allowing the string to run along the building and the holder while entering the guide groove.

(E) Function When setting the binding string to the knot, the string is passed through the hole in the needle and pulled out, and the string is passed along the outside of the knot guide and pulled out to the release side to form a string provided on the bundle release side of the knot guide. When fastened to the locking device and the intermediate portion is inserted into the guide groove through the transverse groove, the string runs close to the bill and holder inside the knot guide.

In this state, the stem culms are pulled into the culm collection part of the binding machine with a packer, and when the amount of collected culms reaches a predetermined amount, the door is sensed and activated, the one-turn clutch is engaged, and the normal binding operation is performed.

(F) Example An example of the present invention will be explained with reference to the drawings.
This tying machine, like the conventional one, has a door on the rear side of the culm collection part 1, a needle 2 on one side, and a knot part 3 on the other side. The knot section 3 is provided with a building 5 and a holder 6 that operate in conjunction with a one-turn clutch, and a knot guide 8 having a guide groove 7 is arranged on the collecting culm section 1 side. A first protrusion 10 is provided on the lower edge of the guide groove 7 of the knot guide 8, and a second protrusion 11 is provided on the upper edge.

Further, on the upper side of the first protrusion 10 of the tubercle guide 8 in the direction of cutting the stem culm, there is provided an oblique transverse groove 12 that connects the guide groove 7 downward, and this transverse groove 12 is shown in FIG. Either the lower side edge 13 is bent inward as shown in FIG.
5, one side of the elastic plate 16 such as a rubber plate is overlapped and fixed, and the other side is overlapped with the step part 15 on the lower side.
The transverse groove 12 does not obstruct the movement of the stem culm that is raked by the packer, and the string insertion operation described later can be easily performed.

Further, a bolt 17 is provided on the rear surface (bundle release side) of the knot guide 8 so as to protrude rearward.
A hemispherical receiver 18 is fitted into the hemispherical receiver 7, and the receiver 18 is fastened with a nut 21 via a coil spring 19 and a seat 20, thereby forming a string locking device.

Next, to explain the operation, the string 22 is passed through the hole 2a of the needle 2 and pulled out as shown in FIG. The middle part of the string 22 is inserted into the transverse groove 12 and held elastically between the
When the string is introduced into the guide groove 7 from the first protrusion 1
It is secured to the upper side of the holder 6 and passed through the vicinity of the building so that it is hooked onto the string hanging protrusion of the holder 6.

When the work is started in this state, the packer scrapes the stem culm into the door and the culm collecting part 1 in front of the string 22 stretched as shown in Fig. As a result, the needle 2 wraps around the collected stem culm, enters into the tubercle part 3 from above the first protrusion 10 of the guide groove 7, is held by the holder 6, and exits. 5 and holder 6 rotate, Bill 5 pinches and winds the two strings 22, Holder 6 cuts the string 22 with its knife and pinches it, and the sweeper enters the upper side of collecting culm 1 and winds it. While moving to the side, the string of the bundle is received by the second protrusion 11, and the knot is removed and released to the rear.

At this time, the end of the string 22 is held in the receiver 18, but it is not wrapped around the building 5, so it can be left as is and used for convenient reasons such as when the work is interrupted or when the string is to be supplied next time. Remove it when the time is right.

(g) Effects of the invention As described above, the present invention provides a nodule guide 8 in front of the building 5 and the holder 6, and the needle 2 enters the nodule guide 8 along the arrangement direction of the building 5 and the holder 6. In this binding machine, a transverse groove 12 is provided on one side of the guide groove 7 of the knot guide 8, and a string stopper is provided on the bundle release side of the knot guide 8, so that the needle 2 Hole 2
There is no need to make a mistake such as forgetting to tension the string passed through a, just lock the string from the needle 2 to the string locking device provided on the release side of the nodule guide 8, hand it over, and let it enter the guide groove through the transverse groove 12. So, nodule guide 8
It can be placed along the building 5 and the holder 6 which are located on the back side of the board and cannot be reached by fingers, so that reliable binding can be performed from the beginning and the string stretched at the beginning can be used for binding. The string 22 does not remain wrapped around the building 5 as in the conventional case, and the troublesome and dangerous work of removing the string 22 can be omitted.
