Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The object of the present invention is a technique for facilitating the threading of a string through a grain culm binding portion such as a binder.

(b) Prior art When threading a binder, etc., it is necessary to pass the string through a string brake device, a slack removal rod, a string guide rod, etc., and finally to the string hole of the needle, and the procedure is complicated.
Since this work needs to be done below the binder transport guide plate, it is a burdensome work for the operator.

As a conventional technique for speeding up cough spinning and simplifying the work, there is a
Publications such as 9-33234 and Japanese Unexamined Patent Publication No. 61-60413 are known.

In the former conventional technique, it is necessary to tie the guide string and the binding string when threading the string, and even if the guide string can pass only through the guide pipe, the string hole of the last needle There was a problem in that it was not possible to pass through until then.

Furthermore, in the latter conventional technology, the operator had to separately thread the string through the string brake device and the slack-removal rod.

(C) Problems to be Solved by the Invention In the present invention, the operator guides the string through the string brake device, through the slack removal rod, and finally through the string hole of the needle. This is done mechanically using a flexible rod to pass the string through.

In the automatic spinning device configured as described above, the present invention provides that a guide pipe for guiding the string passing flexible rod in which the binding string M is locked is arranged from the vicinity of the string case to just before the needle; It was constructed so that the binding cord and the flexible rod could pass through the inside of the tube.

This made it possible to accurately guide the binding cord to the cord brake device, the slack-removal rod, and the cord hole of the needle, and also to protect the cord brake device from dust by using the guide pipe 1. Furthermore, by cutting out the middle part of the guide pipe and arranging a slack-removal rod in the cut-out portion, a string can be threaded through the slack-removal rod at the same time.

In addition, a string guide plate is provided to cover the upper part of the string brake device and the slack-removal rod to prevent straw, dust, etc. from reaching them.

8 is arranged near the conveyance path.

The string case 32 is arranged above the mission device between the engine E and the conveyance guide plate C, and the binding string tube A is arranged above the string case 32. The end of the binding string M is taken out from the binding string tube A, and the string is passed through the string hole of the needle 18.

The operating handle 13 is attached to the feeding device for string threading of the present invention.
It is fixed on the frame on the right side of. The feeding device is constructed as follows.

A storage pipe 2 is arranged along the right side of the operating handle 13, and the rear part of the flexible rod 4 through which the string is passed is stored in the storage pipe 2. 29 is the release rod 29 of the binding device
It is.

Next, the configuration of the main part of the feeding device of the present invention will be explained based on the drawings of FIGS. 2, 3, and 4.

A support plate 14 is fixed on the operating handle 13. A recoil device 24 is arranged on the lower surface of the support plate 14.

A coil wire 3a for operating the recoil device 24 projects in a direction perpendicular to the operating handle 13. A recoil handle 3 is attached to the end of the recoil wire 3a.
is permanently installed.

By pulling the recoil handle 3 in a direction perpendicular to the operating handle 13, the recoil shaft 15 rotates and the flexible rod delivery body 6 is driven. Also, when the operator releases the recoil handle 3, the recoil wire 3a is
Then, the recoil 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 flexible rod feeding wheel 6 on the circumference, and the flexible rod 4 through which the string is passed is engaged by both the flexible rod feeding wheel 6 and the guide roller 8. It's something you pull out.

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

The string passing flexible rod 4 is bound in the direction from the storage pipe 2 to the guide pipe 1 by the rotation of the flexible rod feeding wheel 6!
It is necessary to have flexibility in order to have the effect of hooking the JiM and being drawn out, and to bend and pass through the inside of the guide pipe l arranged in a winding manner. Therefore, it is sufficient that the 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.

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

The storage pipe 2 is divided into front and rear parts at the joint 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 in which the binding string M and the string locking protrusion 5 are set 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. 2. The string locking protrusion 5 fixed at the tip of the flexible string passing rod 4 is inserted into the front storage pipe 2a as shown in FIG. , is housed at the rear of the set groove 2c.

A string guide plate 23 is arranged at the front end of the support plate 14,
The string guiding plate 23 guides the binding string M pulled out from the binding string tube A of the string case 32, and the binding string M is guided by the string guiding plate 2.
It passes through the guide hole 23a of No. 3 and is inserted into the guide pipe 1. The guide hole 23a is provided with an arcuate guide surface in the drawing direction so that the string does not get caught. The string guide plate 23 is placed above the string brake device 10 and the slack-removal rod 7, and the string guide plate 23 prevents dust and straw from flowing toward the string brake device 10 and the slack-removal rod 7. It prevents

Before the binding string M is passed through the string hole 18a of the needle 18, it must pass through a string brake device 10 and a slack removal rod 7 to prevent binding errors due to slack. It is configured so that it can be done automatically by pulling.

That is, a string brake device 10 and a brake roller 12 are placed in a pressed state by a 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 brake roller 12 are used to tighten the binding string. When M is pressed, a frictional braking force acts. 20
is a braking force adjustment handle for the braking spring 19.

Next, the configuration of the slack removal rod 7 will be explained.

The slack-removal rod 7 is configured to lock the front and rear ends of the binding cord M, and pull the central portion thereof using a spring-forced ring-shaped rod. It is divided into two parts, the guide pipe 1b and the front guide pipe 1a, and the binding cord M is taken out from the divided part in the direction of the slack-removal rod 7.

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

Therefore, when threading the string, it is necessary to arrange the slack-removal rod 7 concentrically with the guide pipe 1.

In addition, the string passing flexible rod 4 and the string locking protrusion 5 at its tip pass between the string brake device 10 and the brake roller 12 (although it is necessary to do so, it is impossible to pass through in the braking state). Therefore, a device is provided to release the string brake device 10 when the string is threaded.At the same time as the string brake device 10 is released, the slack removing rod 7 is moved to a concentric position of the guide pipe 1 when the string is threaded. The equipment to be placed is being placed.

In other words, the string passing arrangement lever 9 plays this role.

The lace placement lever 9 is fixed to an arm 16 that is pivoted to the recoil shaft 15, and by rotating the lace placement lever 9 while spinning, the arm 16 rotates and engages with the arm 16. The set arm 17 is rotated. The set arm 17 is fixed to the brake roller shaft 22 of the brake roller 12 , and a brake release cam 21 is fixed to the upper end of the brake roller shaft 22 . It moves by rotation to open the upper end of the string brake device 10 whose lower end is pivotally supported. The space opened by the brake release cam 21 in the string brake device 10 allows the string locking protrusion 5 and the string passing flexible rod 4 to pass through.

At the same time, a coiled spring portion constituting the base of the slack-taking rod 7 is fixed to the brake roller shaft 22, and the slack-taking rod 7 is connected to the guide pipe 1 as shown in FIG. They are rotated to concentric positions. In order to prevent the slack removing rod 7 from passing over the concentric position of the guide pipe 1 due to the rotation of the string passing arrangement lever 9,
The slack-removing rod stopper 11 is arranged on the side surface of the guide pipe 1 opposite to the slack-removing rod 7.

With this configuration, when threading the string, first rotate the string threading arrangement lever 9 to set the string threading state as shown in FIG.
By pulling the recoil handle 3 with the binding string M set in the setting groove 2c in the figure, the string passing flexible rod 4 and the string locking protrusion 5 are pushed out from the storage pipe 2.
A binding string M is hooked on the tip, passes through the string brake device 10 in an open state, passes through the slack-removal rod 7 arranged in a concentric position, is guided inside the guide pipe l, and is connected to the tip of the needle 18. The protruding state of the string passing flexible rod 4 is stopped by the stopper 4a at a position where it comes out in a substantially perpendicular direction and passes through the inside of the string hole 18a.

The operator takes out the binding string M that has passed through the string hole 18a and hooks it into the state shown in FIG. 4 to set it.

FIG. 4 shows a plan view of the binding device part, and the binding string M is engaged with the positioning piece 25 fixed to the right end of the knot frame 27 to determine the position accurately, and the end is connected to the discharge rod in the stored state. 29 Locking piece 2 provided on the drive crank arm part
Hook it to 6 and stop it. In this state, when the tying clutch door 28 is pulled and the clutch is engaged to perform tying in an empty state, the tying string M is moved by the needle 18 to the knot building 30 and the knot holder 31 in the knot frame 27.
This creates a state in which the binding string M is guided to the knot holder 31 and held in the knot holder 31. Thereafter, the end of the binding cord M cut by the cord cutting blade is pulled in by the rotation of the release rod 29, and the string threading operation is completed by removing it from the locking piece 26. 33 is a backer.

FIG. 5 is an enlarged plan view of the string brake device 10 and the slack-removal rod 7, and FIG. 6 is a perspective plan view of the same.

As shown in FIG. 6, a string droop prevention plate 32a is arranged on the string outlet hole side of the string case 32, and the binding string M, which is wound into a cylindrical shape and unravels sequentially from the inside, is unraveled all at once. The coiled wire reaches the recoil wire 3a portion of the string guide plate 23 in a wound state, and is configured so that it cannot pass through the acid recoil wire 3a and is not completely missed. Therefore, when the binding cord tube A approaches the final end, the tube state collapses, and the cord sagging prevention plate 32a prevents this from coming out of the cord case 32 in a wrapped state.

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

First, an opening is provided in the middle of the guide pipe 1,
Since the slack-removing rod 7 is interposed in this part, in the case of string threading, the slack-removing rod 7 can be placed concentrically with the guide pipe 1, and the slack-removing rod 7 can be inserted by inserting the string-passing flexible rod 4. It is now possible to thread a string through the inside of the bag.

Second, at the opening of the guide pipe 1, a slack-removal rod 7 is installed.
Since the slack-removing rod stopper 11 is placed at the position where the slack-removing rod 7 is placed when the string is threaded through, the slack-removing rod 7 does not go too far when it is rotated, and can be accurately aligned with the center of the guide pipe 1, thereby eliminating slack. Mistakes such as engagement between the handle rod 7 and the flexible string threading rod 4 no longer occur.

Thirdly, since the string guide plate 23 is arranged upstream of the string brake device 10 and the slack-taking rod 7, there is a possibility that the string guide plate 23 may fall from the conveyance guide plate C onto the string brake device 10 or the slack-taking rod 7. This eliminates the accumulation of dust and straw debris, and eliminates the problem of inconsistent brake pressure due to debris getting stuck in the string brake device 10, and the problem of straw debris getting on the slack removal rod 7.
