Description

[Detailed description of the invention] The present invention relates to a bunch winding device that is attached to a type of winder that cannot be equipped with an automatic bunch winder and performs bunch winding manually. To provide a device that can be easily attached to a type of winder that cannot be equipped with a winder and can easily and accurately perform bunch winding.

Although various automatic bunch winding machines have already been developed, there are many winders that are difficult to attach to older model winders due to the time and expense required for modification or the accuracy of the winder. In order to form a bunch winding on a bobbin tube in a winder that cannot be equipped with such an automatic bunch winding machine, prior to winding, the yarn to be unwound is pulled out by eye amount by the yarn length required for bunch winding, and then The thread that has been pulled out is inserted into the lumen of the bobbin tube from the side that is fitted into the cradle, then set in the cradle and winded, and when it is wound up, the inserted thread is removed from the cradle and removed from the lumen of the bobbin tube. is pulled out and manually wrapped around the bunch winding part of the bobbin tube to form a bunch winding.

In this process, there is a risk that threads that are intertwined with each other in the lumen of the bobbin tube may be cut when pulled out or untangled and stretched, reducing productivity. With high-count thread, it untwists and loses its strength when it is untangled and bunch-wound, and it also has the disadvantage of breaking in the next process, which combined with the increased man-hours, causes a decline in productivity.

By adopting the configuration described in the claims for utility model registration, the present invention can be easily attached to a type of winder that cannot be attached with an automatic bunch winder, etc.
Prior to winding, bunch winding can be performed easily and accurately by hand, thereby improving the productivity of older model winders.

The configuration of the illustrated example will be explained below.

In the drawing, a guide arm 6 is rotatably supported by a shaft 7 on a support plate 5 fixed to a cradle 3 for supporting a bobbin tube 2 of a winder 1 with bolts and nuts 4. and guide arm 6
The guide arm 6 is constantly given a rotational force in the direction of arrow A by a spring 8 whose end is locked.

A stopper 9 for stopping the guide arm 6, to which a rotational force is applied by a spring 8, at a predetermined position is integrally formed and bent on the support plate 5 described above.

Further, a thread guide 11 is attached to the tip 10 of the guide arm 6 with a screw 12. This thread guide 11 is attached to extend in the length direction of the guide arm 6, and has a long hole 13 running in the length direction, and by fitting a screw 12 into this long hole 13, the thread guide 11 are adjusted in position forward and backward in the length direction of the guide arm 6 and fixed. Note that a thread guiding groove 14 is provided at the tip of the upper end surface of the thread guide 11.
is formed.

An arcuate end arm 17 whose lower end is an arcuate portion 16 extends integrally from the rear end 15 of the guide arm 6 described above. In the illustrated example, the arcuate end arm 17 is vertically arranged.

The bunch winding device having the above-described structure is assembled to the cradle 3 of the winder 1 as described below.

That is, as shown in FIG.
When the support plate 5 is fixed with the bolts and nuts 4 and the guide arm 6 comes into contact with the stopper 9 of the support plate 5 and is stopped, the thread guiding groove 14 of the thread guide 11 is shown in FIG. As shown in FIG. Now, it is opposed to the flat portion 21 of the unit housing 20 that supports the traversing drum 19.

The lengths of the guide arm 6, thread guide 11, and arcuate end arm 17, as well as the mounting position of the support plate 5, are such that when the cradle 3 rotates and the bobbin tube 2 comes into contact with the traversing drum 21, The arcuate portion 16 of the arcuate end arm 17 slides on the flat portion 21 against the elasticity of the spring 8, thereby causing the guide arm 6 and the thread guide 11 to tilt, and the thread guiding groove 14
is selected to be guided outside the confines of the spool section 22 of the spool tube 2, and the components are assembled operatively as described above.

The bunch winding device according to the present invention has the configuration described above and is used as follows. That is,
As shown in FIG. 4, when the cradle 3 is placed in the standby position and the bobbin tube 2 is inserted, the thread guiding groove 14 of the bunch winding device faces the bunch winding portion 18 of the bobbin tube 2, so that a full bobbin can be obtained. The thread end 24 is pulled out from the thread 23 and inserted between the end edge 25 of the bobbin tube 2 and the adapter 26 of the cradle 3, and the drawn thread 27 is fitted into the thread guide groove 14.

Next, the bobbin tube 2 is manually rotated, and the bunch winding 2 is attached to the bunch winding portion 18 as shown in FIG.
form 8.

Next, when the cradle 3 is tilted so that the bobbin tube 2 comes into contact with the traversing drum 19, as the tilting progresses, the arcuate portion 16 of the arcuate end arm 17 touches the flat portion of the fixed member represented by the unit housing 20. 21, and finally reaches the state shown in FIG.
It will automatically come off from 4.

After this state is reached, normal winding is performed, and after the bobbin tube 2 is full, the cradle 3 is returned to the position shown in Fig. 4, the bobbin tube 2 is replaced, and the above-mentioned operation is repeated. is repeated.

The bunch winding device according to the present invention has the configuration and operation described above, has a simple structure,
It can be easily attached to a type of winder that cannot be attached with an automatic bunch winder, and there is no need to modify the winder, etc., so the work time required for attachment can be shortened and equipment costs can be reduced. .

Furthermore, since the position of the yarn guiding groove can be freely adjusted and selected by adjusting the position of the yarn guide with respect to the guide arm, there is an advantage that it can be applied to various types of winders.

Furthermore, since bunch winding can be easily and accurately performed manually, the productivity of winders that cannot be equipped with an automatic bunch winder can be significantly improved.
