Device and method for further processing of coiled fiber tow

Abstract

In the fully automated production of hollow fiber bundles, the fiber bundles wound on a two-point coiler must be transported to further processing stations, for example to rewind and fix the fibers with films. An economical solution is sought for this purpose, which enables flexible arrangements between coiling and further processing. In the proposed solution, the entire coiler is not rotated for further processing, but the fiber bundle is grasped by two clamps (27, 28), cut near the two support arms (2, 3) and controlled by a control device (30) Transport the fiber bundle to a further processing station (optional if necessary) to remove the fiber bundle (11) from the coiler. Aspirate the fiber segments separated from the 180° turning area. In contrast to the coiling process, short-cycle further processing equipment can serve two or more coiling stations. This method is suitable for processing sensitive rolled objects, such as hollow fibers for dialysis filters, which should be rolled up on a two-point coiler and where the fiber bundles should be cut.

Description

technical field [0001] The invention relates to a device and a method for supplying subsequent operations with fiber bundles coiled on a so-called two-point coiler (2-Punkt-Haspel) in a fully automated process, in particular for dialysis Fiber bundles of hollow fibers for filters and similar filter devices, e.g. for wrapping the fiber bundles with a membrane and separating them into individual bundles. In particular, it is necessary for this to remove the fiber bundle from the coiler and transport it to a further processing station. Background technique [0002] At the "two-point coiler" (also known as "two-fork coiler" or "two-point coiler"), there are only two support arms for receiving the rolled object, thus the The fed fibers are wound into linear bundles. This structure is mentioned in EP 0 309331 B1, JP 00 2009 234 680 A, JP 00 2008 280 111A, JP 00 2003 300 672 A, US4666543, JP 000H05161830 A and FR 00000 267 4231 A1 and other public documents, However, no automati...

Problems solved by technology

Due to the connection of the above entities, it is not possible to change to other devices in the event of further processing failures

[0005] A further disadvantage is the footprint of the device: Since the coiler and the further processing station have to be placed directly next to each other, the structural width of the device, seen in the direction of fiber transport, is very large, which is very common in practice disadvantageously affected by the fact that the fiber supplied by the textile machine has to be distributed to three or four coiler installations
