Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an apparatus Vc for producing beaded decorative threads (decorative threads) used in knitted fabrics and the like.

(Prior Art) Devices for making decorative threads by intertwining two or more types of threads are known, for example, as described in Japanese Utility Model Application Publication No. 59-1898788, Japanese Utility Model Application Publication No. 60-60472, etc. . This design yarn manufacturing equipment is designed to manufacture various types of loop yarns, curled yarns, and other decorative yarns by twisting floating yarns and core yarns, and also using presser yarns depending on the required Vc.

By the way, in order to manufacture the bead-containing decorative thread in which beads are inserted into the above-mentioned decorative thread, an apparatus that is slightly modified from the above-mentioned conventional apparatus is used.

That is, as shown in FIG. 9, in the conventional method, a bead feeding disk and a stopper for preventing the beads from moving are placed in the middle of the movement path of the core yarn 0υ into which beads (21) have been inserted in advance. Provided, the outside of the disc (15)! Form a concave part on 1lrTJ to receive each bead holder one by one, and insert a disc (
15) Wrap the core yarn al+ around the outer peripheral surface of the disk (21)
Rotate at a speed lower than the moving speed of the core thread 0υ, and while sliding the core thread 0υ and the disk, the stopper holds the nine pieces (21) one by one in the recess. (Problem to be solved by the invention) In the conventional method V'c, beads acI are fed out onto the core thread 0υ at regular intervals. For example, bead shafts are inserted one by one into the receiver, but since the size and shape of the beads 0I are irregular, the recessed part 1
94), it is a mistake to accept 2 individuals or not to enter at all.

Furthermore, if the beads are arranged at regular intervals, the beads will appear regularly on the surface of the knitted fabric, impairing the design effect of the knitted fabric. It is desired that they be arranged at regular intervals.

However, in the case of the conventional disk-feeding knife, there is a recess (
The nine slopes were formed at equal intervals in the same direction, and could only be supplied at regular intervals.

So, Kibatsu F! A provides an apparatus for producing a bead-containing decorative thread that can accurately and accurately supply beads one by one onto a core thread, and can also supply beads at irregular intervals. The purpose is to

(Means for Solving the Problems) The feature of the present invention is that beads 04 are arranged at predetermined intervals.
In an apparatus for manufacturing a beaded design thread (81) by inserting a floating thread (4) tl- into a core thread (5) and twisting it together, the floating thread (4) t- of a core thread (6) before being twisted together. A stopper 10) is provided in the middle of the movement path to allow movement of the core yarn (6) but prevent movement of the beads (13). The first bead OJ in contact and the next two
A separator (11) is inserted between the second beads (13) to completely prevent the movement of the second and subsequent beads, and releases the engagement between the first beads a3 and the stopper flol. In order to allow the first bead 03 to move together with the core yarn (6), a driving device a? is used to move the separator (11) and the stopper (10) relative to each other at predetermined intervals. It is at the point where J was thrown.

(Function) According to the present invention, the core yarn (5) has a large number of beads a in advance.
3 is inserted. The beads on this core thread (6) are stopped by a stopper tiol Vc, the core thread (6) passes through the center hole of the stopped bead 〇4, and the core thread (6)
and the floating yarn (4) are twisted together to form a design yarn (8).

When the dam of the stopper (10) is released, the bead thread moves together with the core string (61), but in the present invention, the first bead α that is in contact with the stopper (II) l,
A separator (11) is inserted between the ends of the next second bead. Therefore, the second and subsequent bead bets are SEHA L/
- It is dammed by the tank (11). In this state, the separator (11) and the stopper (101t) are moved relative to each other to release the engagement between the first bead 03 and the stopper (lO). Due to this release of engagement, only one of the first beads 03) is removed from the core thread. (5) and is twisted together with the floating yarn (4), thereby fixing the bead a4 in the design yarn (8).

Next, by returning the phase N positional relationship between the separator CIl+ and the stopper tlol to the original state, the second bead ca: (l ka Beads are formed. By repeating such an operation, beads fiIj!1c are supplied to the twisting section one by one.

By operating the drive device U for relative movement of the separator (11) and the stopper (Ql) at irregular intervals, the supplied beads are arranged at irregular intervals on the design yarn.

(Actual example) Below, 5! of the present invention! i! Examples will be explained in detail based on the drawings.

In Figure 1, 11) is the frame of the design twisting machine i,

It has a shaped notch, and the rear weir plate also has a semicircular notch 081t. ! ! As shown in Fig. 86, the V-shaped notch aη on the front side is located at a higher position than the end of the semicircular notch on the rear side. The rear weir plate αQ is in contact with the receiving gutter (9), and there are approximately 6 beads (l) between the front and rear weir plates 115)M.
Sufficient gaps are formed to line up (19). Then, #εV-shaped notch (lη and semicircular notch (18)
The core thread 15) is configured to move around the bottom of the core thread 15).

The bead (+3) inserted through the core thread i5) comes into contact with the same edge of the notch αη (19) of the front and rear weir plate slopes 01G and is prevented from moving.

The separator (11) has a full V notch (I cutout) on its upper edge as shown in FIGS. (ll is arranged so that the n-th knife is inserted from below between the first bead end that is in contact with the front weir plate (16JVc) and the next second bead αJ. Moreover, this separator 111 is sandwiched between the front and rear weir plates 1115) 081 and can freely move up and down.

The movement is blocked by H, and the state returns to the original state shown in FIG.

The body IIJ device that moves the separator (Ill) up and down
u-ka! As shown in Figure 186 and Figure 7, the cam mechanism (2
It has a phantom and an intermittent drive mechanism.

The cam mechanism has a cam surface formed on the lower surface of the separator (11) and a cam roller that slides into contact with the cam surface. It reciprocates to move the separator (Ill' up and down).

In addition, this cam mechanism is manufactured by υ, and the crank mechanism is manufactured by 4 companies.
An eccentric cam (not shown) may be used to move the separator fll+ up and down.

The intermittent drive mechanism described in IrrI has an example of a clutch that turns on and off the operation of the cam mechanism, and a control section (21) that operates the on and off of this clutch. That is, this clutch area is interposed in the crankshaft of the crank mechanism 4, and turns on/off power transmission between the input shaft device and the crankshaft 28I1). This input shaft device is driven to continuously rotate at a constant speed from a drive source that drives the pinch roller (2) etc. via an appropriate speed change mechanism.

The control unit includes a rotating circular root, a next detection unit (sensor 3z that detects the passage of Ill) protruding from the outer peripheral surface of the disk field,
In response to the detection signal from the sensor 3Z, the clutch is configured to issue an on/off command from a special output control panel.

The detection units 3υ at the edge of the rotating disk are arranged at unequal intervals in the same direction. The detection portion 11 is not limited to a protrusion and may be a slit. The sensor sensor is a photoelectric type or a magnetic sensor.

The rotary disk edge is driven from the input shaft via gears and pulley '361G71. As shown in FIG. 8, since this pulley 3η is an eccentric pulley, the rotation circle root puller rotates at an inconstant speed. Inconstant speed rotation of this rotating circle root pull,
Due to the unevenly spaced arrangement of the detection parts '31), -T
35 operates irregularly, so that the clutch heat operates at irregular intervals. Therefore, the separation rake (1
Since 1) also moves up and down at irregular intervals, the delivery of beads α4 becomes irregular.

Note that the present invention is not limited to the above embodiments,
For example, the drive device α2 that causes relative movement between the separator (11) and the stopper flol is configured to move the separator (11)
After blocking the movement of the second and subsequent beads, move stopper 1]α and connect the first bead α4 and stopper (
It may also be one that releases the engagement with 1ol.

However, the drive device U2I may be a cam mechanism (instead of the cam mechanism 2IJ, an air cylinder or the like may be used to move the separator (Ill up and down).

Furthermore, the intermittent drive mechanism 4 may operate at a constant speed or at equal intervals.

(Effect of the invention) According to this Jul, even if the beads are of irregular size, it can be done reliably and correctly. Beads can be fed out one HC at a time. Since the beads can also be fed out at irregular intervals, it is possible to improve the design effect and produce a decorative thread containing beads.
