DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winder for a knitting knitting unraveling machine for winding a yarn unraveled with a knitting unraveling machine into a winder and reusing the yarn.

[0002]

2. Description of the Related Art Knitting is inevitably caused in knitted knitted fabrics, but such knitted fabrics are loosened once and the yarn is wound around a winder. Such knitting work is performed using a knitting machine, but this type of conventional knitting knitting knitting machine removes knitted fabric by inserting a plurality of winders into a rotating shaft that rotates at high speed at a constant speed. The wound yarns are rewound on each winder. As shown in FIG. 9, the conventional winder (a) has a plurality of rotating wheels (e) and (e) formed by connecting a boss (b) and a rim (c) with spokes (d). The boss (b) is formed in a cylindrical shape in which a frame-shaped body portion is formed by bridging the horizontal rod (f), and the boss (b) has an inner diameter provided with a gap around the outer periphery of the rotating shaft (g) of the unraveling machine. (G). The rotation speed of the winder (a) is adjusted such that one end of the frame plate (h1) orthogonal to the rotation axis (g) of the holding plate (h), which is a cross-shaped frame, is connected to the winder (a). The horizontal plate (f) is screwed to the horizontal shaft (g) with a screw (i), and the frame plate portion (h2), which is in the axial direction of the rotary shaft (g), is pressed against the rotary shaft (g), and is held down by the screw (i). The pressing force of the plate (h) against the rotation axis (g) is adjusted, and the tension is adjusted so as to maintain a proper tension without causing the unraveled thread to be caught.

[0003]

However, the pressing plate (h) is extremely difficult to adjust the tightening force of the screw (i) to obtain a desired contact pressure with the rotating shaft (g). In addition, the knitted knitted fabric uses at least two yarns and more than a dozen or so yarns. The winder (a) is attached to one axis in a series,
Since the plurality of yarns are wound one by one on each winder (a) and simultaneously rotated, it is extremely difficult to adjust the plurality of winders (a) to a uniform contact pressure. . Furthermore, since the contact surface of each holding plate (h) with the rotating shaft (e) rotating at high speed wears out, the contact pressure must be constantly adjusted while measuring the degree of wear. Tightening adjustment is a task that is extremely difficult. Nevertheless, the degree of unraveling of the thread is not perfect,
Frequently, the yarn is caught, which tightens the mesh and prevents the yarn from being released, leaving the winder stopped, resulting in yarn breakage. Therefore,
In spite of the unraveling operation using a mechanical device, there is a problem that one worker is required as a monitor for catching a thread.

[0004] On both ends of a wound yarn (j) wound around a winder (a), a thread jump (k) is formed as shown in FIG. Therefore, when winding the winder (a) around which the yarn is wound again onto the winder for the loom, when the winder (a) is installed in the vertical direction, the lower side over the mountain (k). There is a problem that the yarn pulled out from the thread is caught and hinders the operation of rewinding the yarn.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object the use of magnetism to rotate a winder according to the thickness and number of yarns released from a knitted fabric. Provided is a knitting device for a knitting knitting unraveling machine which completely eliminates a situation where the speed is adjusted and the stitch is tightened due to the hooking of the yarn, so that the yarn cannot be unraveled and the winder remains stopped. It is in.

[0006] Further, there is provided a winder device for a knitting knitting unraveling machine in which the amount of yarn wound around the winder is reduced only at one end of the winder so that the yarn does not cross over. To provide.

A plurality of yarns 3 unwound from 2 are rewound to the winder W, and the rotating shaft 1 is connected to a driving shaft of a motor M via a group of pulleys 4 so as to rotate at a high speed at a constant speed. Further, a plurality of thread guides 6 installed at a constant distance on the rod 5 at a position facing the rotating shaft 1 make the rod 7 reciprocally move left and right in parallel with the rotating shaft 1, The yarn 3 unwound from the knit 2 is guided to be wound on the winder W so as to be hung. Although FIG. 1 shows the knitted fabric 2 knitted with three yarns, when the knitted fabric knitted with four or more yarns is unraveled, the rotating shaft 1 has four or more winders corresponding to the number of yarns. W is inserted and connected uniaxially, wound around each winder W one by one, and wound simultaneously.

In the present invention, the winder device comprises a combination of a winder W inserted on the rotating shaft 1 of the thread unwinder A and a control panel D inserted on the rotating shaft 1 adjacent to the winder W. The control panel D is elastically brought into surface contact with the winder W with a predetermined pressure to apply a predetermined tension to the yarn 3 unraveled from the knitted fabric 2. The winder W is configured to be able to be controlled to a normal rotation state without any difficulty by preventing the stoppage of the stopped state.

As shown in FIGS. 2 and 3, the winder W has a cylindrical shape having a frame-shaped body by bridging a plurality of cross frames 8 between a pair of rotating wheels 7, 7. The pair of rotating wheels 7 is formed by providing a rolling bearing 10 on a boss 9 having a center hole. The rotating wheel 7 is preferably formed of a non-magnetic material such as wood, synthetic resin material, or the like. Further, the rolling bearing 10 is provided with a flange type rolling bearing unit on the inner wall surface of the boss 9 of the rotating wheel 7 and a circular iron plate 10 is applied to the outer wall surface of the boss 9, and the rolling bearing unit is attached to the boss 9. It is preferable to fix it to the circular iron plate 11 by screwing or the like.

The pressure plate 13 is provided with a rolling bearing 19 in a central shaft hole 18, and a plurality of bar magnets 20 are buried at regular intervals on a plate surface concentric with the central shaft hole 18. The connecting rod 21 which is fixed to the pressure plate 13 and protrudes perpendicularly to the surface of the panel is loosely inserted into the through hole 22 of the fixed plate 12 so that the fixed plate 12 cannot be detached from the connecting rod 22 and is assembled so as not to be detached. . The connecting rod 21 has at least 2
It is preferably provided at a location.

The bar magnets 15 of the fixed platen 12 and the bar magnets 20 of the pressure platen 13 are provided with the same type of magnets repelling each other at positions facing each other. 13 can be held elastically with a desired interval. The spacing between the fixed platen 12 and the pressure plate 13 can be variously determined by experimental measurement based on the thickness and the number of the yarns 4 of the knitted fabric 3.

Therefore, in the winder device of the present invention, the winder W inserted into the rotary shaft 1 is rotated by the inner ring of the rolling bearing 10 fitted on the rotary shaft 1 as shown in FIG. Is transmitted to the winder W, and when the yarn 3 is caught, the rotation of the inner ring of the rolling bearing 10 is received by the rolling element, and the rotation of the winder W is stopped and held. Also,
The control panel D is attached to the rotary shaft 1 with the pressure panel 13 in contact with the rotating wheel 7 of the winder D, and the fixed panel 12 is provided with a predetermined elastic force by the repulsive force of the magnets 15 and 20 against the pressure panel 13. The set screw 17 is screwed into the position where the distance is obtained, and is locked to the rotating shaft 1 to be fixed and held. The winder W is provided with a magnet 15 between the fixed platen 12 of the control panel D and the pressure platen 13.

In addition, even if a plurality of winders W corresponding to the number of the yarns 4 pulled out from the knitted fabric 3 are mounted on one shaft and the plurality of winders W rotate at the same time, the distance between the fixed platen 12 and the pressure platen 13 is increased. Since the same and the same repulsive force of the magnet 15 gives a constant pressure to the plurality of winders W, a uniform tension is applied to the plurality of yarns 3 so that the yarns do not become entangled. Even at the place where the tangling is most likely to occur (the place where the thread is drawn out in FIG. 1), it is possible to perform the thread unwinding work almost certainly without any hindrance causing any tangling, and the unraveling work of the knitted fabric is performed unattended. Make it possible.

Moreover, the body of the winder W2 can be formed with a length sufficient to secure the necessary amount of winding yarn, and the extension portion 23 can wind the yarn without disturbing the winding of the adjacent winder. Times can be performed. Further, in the enlarged portion 30, the number of windings of the yarn is reduced, and the yarn is wound without forming a mountain-crossing by the winding yarn.

[0019]

Since the present invention has the above-mentioned structure, the control panel provided with the pressure plate in surface contact with the winder can apply an appropriate elastic pressure due to the repulsion of the magnet provided on the fixed plate and the pressure plate to the winder. By applying the respective rotational speeds of the plurality of winders to the yarn drawn out of the knitted fabric and performing the yarn unraveling, the plurality of yarns unraveled from the knitted fabric are drawn out without causing entanglement. The occurrence of thread breakage is almost completely eliminated. In addition, since the enlarged portion having a predetermined gradient formed on one side of the winder has a small number of windings of the thread and does not cause a mountain crossing, the lower portion of the winding portion allows the lower thread to be pulled out without being caught. It is.
Furthermore, even when a control panel is installed, or when a plurality of spools are connected in a single axis, it is possible to wind the thread without disturbing the adjacent extension. As a result, a large number of winders can be mounted on a single shaft without the need for individual windings, and the required number of winders according to the number of yarns of a plurality of knitted fabrics can be installed on a single axis. It is effective in providing a device for unraveling the knitted material without causing the yarn to be entangled.
