Description

The invention relates to a device stm ejecting and Introducing a winding carrier "outside" or into the axial opening τοη Spools of thread or the like, which have a support table for the spools of thread possesses, has an opening au *. Passage of the winding carrier • ttfftela and the one leather holder assigned to it, which is on the top the thread bobbin.

Such an overhaul is carried out around, for example, cardboard wrap carriers to be exchanged for high-value aetalloae lap carriers mainly used for the dyeing process in the yarn bobbins, and vice versa.

A gate direction has already been proposed, aittels which ejects and brings in a lap carrier from above a support plate, for which purpose a mandrel forms the axis cavity of the one placed on it Thread wrap · interspersed.

dee Auflagetiaches takes place here, namely jevieila through the passage opening through the tissue, which opening about the largest diameter of the winding support · eateprieht. D & s floodplain and pushing in is done by means of Plunger in the interaction of a hold-down device, which during the Uastschlag The position of the bobbin is pulled out by placing the hold-down on the top of the Thread spool leads and this presses against the Auflagetiscn.

For the above-mentioned dyeing treatment of the yarns, it is now advantageous to compress the yarn laps as uniformly as possible, which, due to unavoidable influences during the winding work, develop a more or less different hardness or density, by jointly pressing the large number of laps stacked on a perforated fiber bundle However, it has been shown here that the edges of the coils in particular, due to the special narrow-ply joint zone *, mainly edge zones, impair the homogeneity of the dyeing. To remedy this situation asu, institutions have become known _'f by means of which a flattening of the edges of the wound yarn "is performed. The yarn package is pressed between two shaped cones, removed from the device and sent to further treatment,

The object of the invention is to flatten the shrimp under Use of the known Werkseuge in the cycle of the overturning process of an overturning device su erseugen, including the component such an overturning device.

According to the invention, this task is achieved by the fact that Hold-down device and dl · tabletop dissolving parts for the roll as funnel-shaped plungers are formed, the funnel surface of which has an inner surface Press the thread bobbin edge flattened together.

The step-by-step drive of the support table 2 takes place by means of a Electric motor 9 via a gear Io and a clutch 11 using of a Maltese cross 12, which would come from a cam 13 *

The overturning, that is, the ejection of a cardboard winding carrier 5 * and the pushing in of a new, for example metal winding tape 5 takes place at a single position on the machine * This position is passed one after the other through each funnel body with the yarn bobbin on it. The machine stand Ik there is extended over the table top level upwards. Here, it forms a console 36 which extends freely above the stop of these passage openings 3.

The Umschlagposltion is a Lagenzen tr guiding device 7 ¹ * upstream. With the assistance of an abutment 75, the lap carrier 5 * to be pushed is first driven further into the axle cavity in order to obtain an insertion depth of this lap carrier 5 * that is the same for all yarn laps. As a result, the ejector plunger 38 always has the same point of impact, so that the device works without rejects. The centering plunger 76, which effects the further pushing in, moves for this purpose, passing through the passage opening 3, up to the funnel space 77. As a result, a thread bobbin that has not been placed quite properly is also directed onto the annular shoulder 79 of the ram head. The axial alignment is completed before the upper side 23 of the thread reel 7 is pressed against the abutment, which has a cavity 80 for the entry of the position-corrected lap carrier 7.

The abutment 75 sits on a Haiteetange 8l, which extends with its fastening section radially to the axis of rotation of the table 2 and only then takes a bent course, this in order to achieve a free removal point for the yarn package. The same holding rod 8l carries a pneumatic cylinder 82, the ram 68 of which conveys the yarn package 7a in the radial direction from the table of the device .
