Abstract

A device for storing continuous material, e.g. yarn, wire or strip, has a cylindrical bobbin (4) and a feed eye (12) which rotate relative to one another. A cylindrical casing (23) surrounds the bobbin and feed eye and contains slots (10) which extend in a generally circumferential direction and allow the escape of air and flying dust. <IMAGE>

Description

(54) Equipment for the accumulation of fibrous material

The invention relates to a device for accumulating fibrous material, such as yarn, wire, tape, etc. with material take-up body and feeding loop. for the material, the two parts, namely the winding body and the inlet loop, rotate relative to each other during operation, and further with a cylindrical housing that surrounds the winding body and the inlet loop.

In prior art devices of this type, the housing is formed continuously. Accumulation or storage devices are also known in which slots extending parallel to the axis of the winding body are provided on the housing. In a continuous cabinet, a layer of dust or other contaminants often accumulates on its inner wall during operation. Also, in a cabinet with slots parallel to the axis, occasionally dust from the scraps will remain trapped, thereby gradually decreasing its clearance and the slots eventually clogging completely.

The invention is based on the object of providing a device which is improved in particular in this direction.

The invention is characterized in that it comprises at least one slot extending substantially parallel to the periphery of the cylindrical housing for the air outlet of the debris, dirt, etc.

According to a preferred embodiment of the invention, the slot is located in the region of the circumference of the housing which lies opposite the movable part of the housing, for example against the lead-in loop.

The air slots may be provided along the movable parts and along their rotation path, further in the vicinity of the deflection or return points of the accumulated material or the friction points. This can cause dirt, such as dust, to escape completely. Due to the slot (s) running parallel to the circumference, it is possible to effectively prevent the debris from becoming trapped in the slots themselves, thereby increasingly reducing the clearance of the slot during operation. In the circumferential direction, they are provided in only a small number of webs or surviving housing parts on which the dust could accumulate.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a longitudinal cross-sectional view of a fiber storage device, for example, a weft loom constructed in accordance with the invention; FIG. 2 shows a corresponding detail on a larger scale; FIG. 4 shows a further embodiment of a slot cabinet. FIG.

The eyelet 1 is fed by a lead eyelet 12 rotating about the axis 3a of the winding body 4, essentially cylindrical according to arrow 2, so that a weft winding 13 is formed on the winding body 4. The winding body 4 is secured against rotation by permanent magnets 15, 15a.

Together with the supply eyelet 12, the pot 3, which surrounds the winding body 4, is rotated, leaving a slight play 44 (Fig. 2). The disc 16 performs swaying movements according to arrow 17 during operation without rotating. Through the rolling disc 16, the windings of the winding 13 are gradually moved on the winding body 4 in the direction of the arrow 18. The pot 3 serves to prevent the threads from running in when the winding accumulates in the space 19 left of the winding 16, ie winding from the rear.

On the draw-off side, the winding body 4 is provided with a winding funnel 21, which restricts the yarn balloon 22 formed by the weft 1. Externally, said parts are surrounded by a fixed housing 23. The housing 23 serves as a carrier for the magnet 15. the operator could not injure himself during the operation by the accumulator. The housing 23 has slots 10 running parallel to its circumference, through which air, dust debris and possibly other impurities can escape. In the circumferential direction, relatively few webs 43 are provided between the slots 10 on which dust debris could remain. The slots 10 are provided in the region 41 of the movable parts 12, 16 located inside the housing 23, and hence in the region where a lot of dust debris can be generated as a result of rotating the swaying movement, thread deflection, friction, etc.

The repair of the slots 10 creates a sort of lattice, which can leave the air and flight undisturbed without compromising the operator.

Referring to FIG. 4, helical slits 10 may also be provided in the housing 23. If the pitch of the helical formation is not too great, for example up to about an angle of A = 20 °, the air and dust exits substantially in the parallel direction are favorably influenced. with circumference and clogging in the slots can be avoided.

Also, the rear winding pot 3 has openings 33 at its periphery, which are located in the region of the air slots 10 and through which the circulation of the air purge stream is favorably influenced.

The cylindrical body for winding the material can also be formed, for example, by a cage-shaped magazine or a reel or the like.
