"Spinning machine for man-made fibers"

Spinning machines for man-made fibers are today running at yarn speeds operated at more than 3000 m / min. It is well known that the resulting noise pollution of the operating personnel by the fact that soundproofing devices be provided along the front of the machine. These soundproofing devices impair Of course, the operability of the machine, since they have to be moved to operate, but then different Cover parts of the machine. To remedy this, a spinning machine which has a large number of winding devices has that protrude perpendicular to the machine front, proposed that the soundproofing device as horizontal movable curtain is formed, which is in its protective position the end face of each winding device up to the corresponding curtain of the neighboring winding device covers and stowed in the operating position between two adjacent winding devices will. For this purpose, the curtain can be moved in a straight line between two adjacent winding devices. as well it is possible to place it between two adjacent winding devices Wind up or fold it up like a harmonica and store it.

The curtain is preferably at least partially made of one transparent material, e.g. plastic material. It is also provided that the winding device is ventilated when the curtain is in its shielding position.

The particular advantage of the invention is that the curtain can be moved horizontally on the one hand. This will avoided that by pushing away the curtain other parts of the same spinning station to which the winding device heard, to be covered up. On the other hand, the fact that the curtain between «Woi neighboring winding devices is driven, avoided that the adjacent winder is now on its operating side is covered, and it therefore remains possible to operate two adjacent winding devices at the same time. But it will the adjacent winding device laterally shielded in such a way that the operator can be removed from it The winding device is not noisy.

1.V Each curtain is preferably in its lower area provided with a slot which extends substantially horizontally from its leading edge. Through this it becomes possible that when the thread is applied to the winding device, i.e. when the thread is in a hand-held one Suction gun runs in, the thread can be passed through this slot and the curtain during the thread catching and - can be closed again. In this respect, the advantages can also be achieved with the invention can already be achieved with the soundproofing device according to laid-open specification 31 02 290.

An embodiment of the invention will now be described.

The man-made fiber spinning plant consists of a large number of spinning positions. At each spinning position comes from a vertical one Spinning chute a thread 1. This is from the godets 2 and 3 deducted. From the godet 3, the thread runs to a winding device (winding head 6 with sleeve 5 and Coil 7). The bobbin 7 sits on a winding spindle 8. On the bobbin 7 is the drive roller 9. This drives the Coil 7 with constant peripheral speed. The fadan is moved back and forth by the traversing device 11, whereby the thread sweeps over a traversing triangle. The traversing device 11 with drive roller 9 sits on one Carriage 12, which can be moved in the vertical direction, so that the drive roller in front of the growing bobbin diameter evade and can also be lifted off the coil.

Such a winding device for chemical fibers in spinning machines is described, for example, in the German Offenlegungsschriften 25 26 768 and 25 47 401 (Bag. 946, 980). There, the application device 10 is shown with which the

continuously running threads 1 are applied to the empty tube 5 on the bobbin 8.

Today, man-made fibers are spun at speeds of more than 3000 m / min. Thereby measures of noise reduction and noise insulation required. Iode noise insulation on the front of the machine has the disadvantage that this deteriorates the operability of the machine.

Every winding device is on your to reduce noise The front is covered with a soundproof curtain 15 during operation. This soundproof curtain 15 is made made of a flexible, sound-absorbing and sound-absorbing material. The vertical ends of the curtain 15 are in the clamping bars 16 and 17 clamped. The tension bar 17

is straight in the straight guide 19 in the horizontal direction. The rope 23 is attached to the tensioning bar 17. The rope 23 is guided over the freely rotatable roller 24. A weight 2 5 is attached to its end. 5

The curtain turns around the vertical, freely rotating roller 26 led. The front retaining strip 16 is guided by a telescopic, horizontal straight guide 27. This straight guide 27 consists of several nested and straight pipes or tubes other profiles. The last, greeted profile is guided straight in the stand 28. The retaining bar 16 is in the Stand 28 * of the neighboring winding head locked in a manner not shown. This lock can be released by hand will.

With a handle on the holding power 16 is designated.

The soundproof curtains on neighboring winding heads are constructed identically. It should be noted, however, that the fronts of adjacent soundproof curtains are slightly offset from one another, so that when one of the soundproof curtains is opened, its straight-line guide 27 has sufficient space to move into the area of the neighboring winding head without being hindered by the soundproofing curtain of this neighboring winding head. This is shown, for example, on the straight guide 27 ″ of the neighboring winding head 6 ¹¹ .

As can be seen from Fig. 1, each soundproofing curtain has a distance from the floor insulating plate 13, which forms an insertion gap 20 in the closed state. When operating the machine, the soundproof curtain is now handled as follows: The operator first opens the curtain, cuts the thread, so that the thread from the stationary thread suction 22 is sucked off, operates the winding head in the sense that

the carriage 12 lifts off the full bobbin, removes the full bobbin 7 and places an empty tube 5 on it. He starts then the extracted from the Fadenabsaugung 22 thread mil a hand-held suction gun and puts the thread through the thread guide of the Anlegeinrichtung (not shown) and pulls it with the hand-held suction gun then SMS of the machine out and obliquely downward, wherein the thread further in the Suction gun is drawn in. The operator now actuates the carriage 12 by pressing a button in such a way that the carriage 12 moves downwards and the drive roller moves against the sleeve 5. At the same time, however, the operator pulls the soundproof curtain 15 in front of the winding head by means of handle 21 so that the thread now runs through the insertion gap 20 to the outside.

Now - as in the previously specified laid-open documents described - the feed device in a sequence control triggered by the slide control actuated and the thread applied to the empty tube 5, being caught by the traversing device 11 at the same time will. When it is put on, the thread breaks from the thread suction gun that the operator is holding in his hand. Now the operating process is on one of the pulley heads ends, whereby the operator was largely soundproofed when operating. As a special advantage This has the effect that the soundproofing curtain provides soundproofing to the neighboring one during the operating process Represents winding head.
