Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a multi-spun type winding device used for synthetic fibers and the like.

(Prior art) In recent years, the processing speed of synthetic fiber yarn has become faster and it is not uncommon for the winding speed to exceed 4,000 to 6,000 m/min. Correspondingly, the lifespan of consumable parts has become extremely short, and it has become extremely important to appropriately replace or repair them.

In particular, in winding machines, the traverse tip (which is the guide portion that comes into direct contact with the yarn of the traverse that reciprocates at high speed)
(also called traverse guide) has a short lifespan, with a lifespan of 3 to 4
I replace it with a new one every few days.

(Problem to be Solved by the Invention) However, conventional winding devices, especially multi-spin type automatic winding devices in which two bobbin holders are provided on a rotatable turret to continuously wind yarn. In a traversing device, a box with contact rollers or friction rollers is usually installed in front of the traverse box, and a yarn breakage detector and a traverse fulcrum guide are fixed directly above the box, and a Since the machine is equipped with an instrument box for the take-up roller, etc., the working space in this part is extremely small, and the replacement work is extremely troublesome, and there are also major safety problems.

In particular, if the bobbin holder is long like a 6-piece or 8-piece tip, you may have to put your body between the wine goo head of a traverse box and the traversing fulcrum guide in an awkward position to replace the tip on the back side. Because of this, the work posture is poor and it is difficult to attach the traverse snaps on the back side accurately and securely.As a result, unpredictable accidents can occur in which the traverse tips fly off during raking in a short period of time. The problem was that it was easy.

As a result of extensive studies to solve the above-mentioned problems, the inventor of the present invention found that if the thread breakage detector and the traverse fulcrum guide installed above could be moved together, the work could be done easily and safely. This discovery led to the present invention.

(Means for Solving the Problem) That is, the present invention provides a multi-spun type winding device that winds a plurality of yarns by inserting a plurality of bobbins into one bobbin holder and winding a plurality of yarns at the same time. A support rod is provided parallel to the traverse direction, and a fixed rod held by the support rod is provided parallel to and below the support rod, a thread breakage detector is provided on the fixed rod, and a traverse fulcrum guide is provided on the support rod. This winding device is characterized in that it is provided corresponding to a traverse guide, and the rear end of a support rod is fixed so as to be movable vertically and laterally around the rear end.

(Example) Hereinafter, the present invention will be explained based on the drawings. FIG. 1 is a perspective view of essential parts showing an embodiment of the present invention, and FIG. 2 is an enlarged explanatory view of portion A in FIG. 1.

In the figure, 1 and 2 are respective take-up rollers, and 3 is an instrument box for the take-off rollers, etc. Below this instrument box 3, a multi-spun turret-type automatic winder 10 is arranged.

The automatic winding machine 10 mainly includes a rotatable turret 11.
9 wine spindles 12 (only one is shown), which are horizontally protruding from the top and which wind the yarn by inserting bobbins, and a wine goo head 13 located above the drive spindles 12 (only one is shown). The head 13 consists of a holding box 14 for a contact roller 15 that is driven in contact with the bobbin, and a traverse box 16 that has a traverse guide (not shown) placed in front of the box 14 at a certain interval and corresponding to the number of bobbins to be taken up. It is housed in a slide block (not shown) so that it can be moved.

18 is the traverse box 16 of the wine goo head 13
A supporting wood for a traversing fulcrum guide 19 is horizontally disposed parallel to the gap 17 between the contact roller and the holding box 14 and at a position almost directly above the gap 17, and the support rod 18 is provided with the center of the traversing fulcrum at a predetermined interval. Traverse fulcrum guide 1 at the position where
9 is installed.

The support rod 18 has its rear end facing upward and downward as shown in FIG.
It is installed so that it can be moved left and right (horizontally). That is, a channel-shaped receiving frame 20 having a lower shaft 21 is rotatably provided in the left-right direction on a bracket 23 attached to the instrument box 3 via a toothed washer 22, and a support shaft 24 attached to the receiving frame 20 is provided so as to be rotatable in the left-right direction. The rear end of the support rod 18 is pin-coupled to the support rod 18, and is held movably about a support shaft 24 in the vertical direction. 25 is a spring washer or spring pin that fixes the lower shaft 21 protruding from the hole of the bracket and suppresses vertical movement.

Further, below the support rod 18, a holding rod 26 is suspended via connectors 28 and 29 to which a thread breakage detector 27 arranged corresponding to the traverse fulcrum guide 19 is attached to the support rod 18. A plate 30 provided on the side connector 28 is fixed with wing bolts 32 to a bracket 31 attached to the instrument box 3, so as to restrict the movement of the support rod 18, but if the support is sufficient, it will not work. However, it is not limited to this.

Further, a holder 33 is attached near the bracket 23 to temporarily hold the support rod 18 out of the way when replacing the traverse guide.

The holder 33 consists of a hollow circular receiver 34 fixed to the instrument box 3 and a holder arm 36 with an inverted lower end 37 rotatably inserted into the hollow hole 35. is a horizontally protruding pin 38 provided on the holding arm 36.
The pin 38 is placed in the direction along the instrument box 3 by entering the slit 39 carved in the upper end of the receiver, and when in use, the pin 38 is inserted into the slit 40 carved at a position approximately 45 to 90 degrees away from the slit 39. By inserting the holding arm 36 into the instrument box 3, the holding arm 36 is rotated and protruded from the instrument box 3 toward the support rod 18 and is used in a fixed state.

Further, a protrusion 41 is provided at the tip of the holding arm 36 to prevent the support rod 18 from falling off the tip when placed on it.

Although the brackets 23, 31, receiver tube 34, etc. are attached to the instrument box 3, it is needless to say that they are not limited to this and may be attached to the machine base, a pond box, or other items. . Further, since the support rod 18 can be moved and supported at an appropriate location such as the instrument box 3 or the machine stand, it is preferable to install the holder 33, but it is not necessarily required.

In such a device, when replacing the traverse guide due to damage or periodic inspection, first hold the tip of the support rod 18 and tighten the wing bolt or wing nut 32.
Loosen the fixation with the slit hole 42 of the plate 30, move it to the side, and lift it upward.

After that, pull up the holding arm 36 and attach it to the support rod 18.
Rotate it to the side, insert the pin 38 into the slit 40, and fix it.

Next, the support rod 18 is lowered until it contacts the holding arm 36, and the support rod 18 is placed thereon. At this time, as shown by the two-dot silver line in FIG. 1, there is almost nothing obstructing the upper part of the winder head 13, that is, the traverse box 16, and the traverse guide can be replaced easily, safely, reliably, and accurately. Can be done.

(Effects of the Invention) As explained above, according to the present invention, the replacement work of the traverse guide becomes extremely easy and safe, the installation becomes reliable and accurate, and the unpredicted damage to the traverse guide is reduced, and at the same time, the replacement period is reduced. This has the remarkable effect of making it possible to extend the period.
