Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spirally wound plural number of windings of a tape-shaped fiber bundle having a width remarkably smaller than the holding band on a circulating endless holding band. A fiber bundle feeding device having a edging device for the fiber bundles which is laterally movable relative to the holding band for feeding and is fed to the holding band, and for a fiber bundle which has already been placed on the holding band and has arrived at the holding band And a device for detecting the longitudinal extension of the fiber bundle winding or the extension of the longitudinal edge forming the contact edge of the fiber bundle.

[0002]

2. Description of the Prior Art A bundle of fibers is placed in a plurality of parallel windings on a circulating endless holding strip and is already placed on the holding strip in order to be able to bring the edges of the individual windings into precise contact. It is known to adjust the lateral feed of the holding band with respect to the feeding device according to the longitudinal extension of the fiber bundle windings forming the respective contact edges (EP 12396).
No. 9). For this purpose, the marker thread is fed in synchronism with the fiber bundle and, due to the extension of the marker thread detected by the row camera, a drive device for the lateral feed of the holding band to the feeder, which is fixed in this case, is provided. Take out the controlled variable. However, the disadvantage of this known device is that, due to the relatively large mass to be moved, a sensitive adjustment of the lateral feed drive of the holding band is possible only at high cost, and a given bundle of fibers to be placed on the holding band. At the lead angle, the supply of fiber bundles in the circulation direction of the holding band lowers the placement accuracy, and there is a risk of improper stretching of the fiber bundle that reaches the holding band.

[0003]

Accordingly, the problem underlying the present invention is to improve the device for placing fiber bundles on a circulating endless retention band by simple structural means, and to place them sequentially on the retention band. It is to be able to accurately wind the fiber bundles in parallel.

[0004]

In order to solve this problem, according to the invention, a feeding device with an edging device is arranged at right angles to the fiber bundle or to a holding band in the fiber bundle feeding range. Related to the longitudinal or longitudinal extension of the winding of the fiber bundle, which is rotatably supported about a swivel axis which extends and which is provided away from the point where the fiber bundle hits the retaining band and which forms the contact edge. The turning can be adjusted.

[0005]

Since the feeding device can swivel about the swivel axis extending at right angles to the fiber bundle or the holding band, the fiber bundle that arrives at the holding band is first provided with a predetermined lead for winding the fiber bundle. It is possible to point in the direction of the corners, which provides advantageous conditions for the precise mutual contact of the edges of the individual fiber bundle windings. Since the swivel axis of the feeding device is provided away from the point where the fiber bundle hits the holding band, the fiber bundle reaching the holding band can be easily displaced at right angles to its longitudinal direction. The fiber bundles arriving at the retention zone may be displaced from their immediate extension if it is necessary for the precise connection of the edges of the next fiber bundle winding due to the irregular extension of the fiber bundle windings placed on the In addition, the swivel adjustment described above can be used particularly advantageously. The lateral displacement of the fiber bundle due to the swiveling adjustment of the feeding device is superimposed on the driving of the lateral feeding of the feeding device, which is carried out with respect to the holding band according to the predetermined lead angle, and in special cases an additional lateral feeding. Even if various interventions are possible, it is not necessary to intervene in this lateral feed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Assuming that a certain width of a fiber bundle placed for edging the fiber bundle arriving at the holding band can be taken into consideration, the holding band on the holding band is controlled in the supply range in order to control the turning position of the feeding device. It is only necessary to detect the vertical extension of the.
In general, however, this is not the case, and in another configuration of the invention, a device for detecting the position of the connecting edge of the fiber bundle coming into the holding band between the edging device and the point where the fiber bundle being fed hits the holding band. A device for detecting the longitudinal extension or longitudinal edge extension of the fiber bundle winding already placed on the holding band is used as a target value transmitter and the connecting edge of the fiber bundle coming to the holding band. If the device for detecting the position of is connected as an actual value transmitter to the swing adjustment regulator of the feeding device,
Very precise adjustments are made. Since the contact edge of the winding of the fiber bundle placed after the measurement is different from the straight extension, when a deviation between the actual value and the target value is confirmed, the turning drive device for the feeding device is arranged to cancel this deviation. The fiber bundle arriving at the holding band is urged to accurately contact the contact edge of the already wound fiber bundle winding so that the deviation of the contact edge extension is followed.

In order to detect the position of the connecting edge of the fiber bundle arriving at the holding band, different sensors can be used if the extension of the edge can be accurately determined without adversely affecting the fiber bundle. can do. In this respect, however, a particularly advantageous situation is obtained by means of a device consisting of an optoelectronic receiver which is directed to the turning piece for the fiber bundle. This is because, as is well known, measurement can be performed through a photoelectric receiver, especially a row camera, and the fiber bundle turning piece can detect how the fiber bundle extends with respect to the measuring device.

The drawings show an embodiment of the invention.

The device for placing the fiber bundle 1 on the circulating endless holding band comprises a fiber bundle supply device 3, which is arranged along a guide rail 5 via a carriage 4 and around a turning roller 6. It is laterally displaceable with respect to the holding band 2 which is guided and seamed into a flexible tube. A rack 7 parallel to the guide rail 5 is used to drive the housing 4 and meshes with a pinion 9 driven by an electric motor 8. The supply device 3 itself has an unwinding device 10 for the fiber bundle winding body 11 and an edging device 12 for the fiber bundle 1 that is unwound from the fiber bundle winding body 11 and reaches the holding band 2. Before reaching the belt conveyor 14, the fiber bundle 1 drawn out from the fiber bundle winding body 11 first passes through the free hanging section 13 and then the belt conveyor 14 in order to cancel the internal stress caused by winding. Drawer roller pair 1
The fiber bundle 1 is tensioned between the fiber bundle 5 and the fiber bundle 5, and the edge trimming device 12 trims the edge accurately. The trimmed fiber bundle 1 is then fed via a turning piece 16 to a holding band 2 for holding a single-layer or multi-layer mounted fibrous web consisting of a plurality of parallel windings mounted with a given lead angle. Form on band 2.

In order to allow the fiber bundle 1 drawn out from the fiber bundle winding body 11 and trimmed by the edging device 12 to be accurately placed on the circulating holding band 2 at a predetermined lead angle, The bundle 1 is directed through the feeder 3 in the direction of the lead angle. For this purpose the feeding device 3 is
A swivel bearing 17 extends at right angles to the fiber bundle 1 or at right angles to the holding band 2 in the region of the region 18 where the fiber bundle 1 hits the holding band 2 and away from the point 18 hitting this holding band 2. Since it is pivotably supported about the pivot axis provided, the pivotal adjustment of the feeding device 3 causes a lateral displacement of the fiber bundle 1 fed to the holding band 2. Thereby, an additional lateral movement is superimposed on the uniform lateral feed of the fiber bundle 1 via the carriage 4, and the irregularity of the extension of the contact edge of the finally wound fiber bundle is canceled. be able to. That is, the fiber bundle 1 supplied to the holding band 2 is supplied to the supply device 3
Due to this irregularity, the contact edges are tracked via the swivel adjustment of the, so that a precise connection at the edges of the individual fiber bundle turns is ensured.

A swivel cylinder 19 is provided for swiveling and adjusting the supply device 3 with respect to the carriage 4. The swivel cylinder 19 is pivotally attached to the carriage 4 and the supply device 3, and hydraulic pressure can be applied to both sides. The control of this hydraulic pressure application is carried out via a suitable valve 20 in the hydraulic conduits, but for clarity only one of these conduits is shown schematically in FIG. The actuating device 21 for these valves 20 comprises a feeding device 3 for the carriage 4.

Furthermore, the adjusting device 23 comprises a device 24 for detecting the extension of the longitudinal edge of the fiber bundle winding 2a which has already been placed on the holding band 2 and forms the contact edge for the fiber bundle 1 coming to the holding band 2, Device 2 for detecting the position of the connecting edge of the fiber bundle 1 coming to the holding band 2
5 is connected to. The measured value of the device 24 concerning the position of the contact edge of the fiber bundle winding 2a with respect to the width of the holding band 2 serves as a target value, the actual value determined by the connecting edge of the incoming fiber bundle 1 being fitted to this target value, The incoming fiber bundle 1 is made to properly follow the already placed fiber bundle winding 2a. When the actual value-target value deviation is confirmed by the adjuster 22, the valve 20 is controlled so as to eliminate the actual value-target value deviation, so that the lengthwise extension of the already placed fiber bundle winding 2a is extended. The output signal of the device 24 for detecting the
It serves as a reference amount for the lead angle when the fiber bundle 1 is placed on the top.

The device 25 for detecting the extension of the longitudinal edges of the fiber bundle 1 arriving at the holding band 2 is preferably configured as a row camera, and the fiber bundle winding to be newly contacted with the already placed fiber bundle winding 2a. Necessary for accurate position detection by detecting the connecting edge in the range of the turning piece 16 for the fiber bundle 1 between the drawing roller pair 15 and the point 18 where the fiber bundle 1 hits the holding band 2. The correspondence between the different fiber bundle 1 and the photoelectric receiver 25 is structurally defined. A light source for illuminating the fiber bundle to be detected may be provided on the side of the turning piece guide section, which is opposite to the row camera.
