Description

Segmented warp beam and creel of the combined device

The invention relates to a segmented warp beam having a shaft core, two side flanges at both ends of the shaft core, and a clamp strip.

The invention also relates to a creel of a combination device having at least one warp beam mount for receiving such a segmented warp beam and a creel outlet.

The hank is drawn from at least two, but typically more, segmented warp beams, which are integrated into a combined device to form a warp beam. In the course of this integration, it is also possible for the skein to be processed again, for example by the application of a sizing.

In order for the skeins to be integrated, the segmented warp beams must be placed in a creel that is placed in front of the inlet of the combination. In order for the combined process to be ready, the skein must be drawn from each segment through the shaft and pulled to the inlet of the assembly. This is usually done by an operator, and the yarns arranged on a segmented warp beam form a bundle of yarns, so that all of the yarns of the respective warp beam can be obtained in two hands. The bundles of yarns are pulled up by the operator to the entrance of the combination. Here, it is practically inevitable that the yarns will be impacted by the lateral traction component, that is, a traction component will cross the longitudinal extent of the yarns. this It means that a specific length of one of the yarns of each segmented warp beam cannot be utilized.

Moreover, this preparation is laborious and time consuming. Even when the segmented warp beam is not braked, a worker needs a significant pulling force to pull the guide yarn from the segment warp beam and bring the yarn into the position at the entrance of the combination device. .

The present invention is based on the convenience of preparing skein for assembly purposes.

This object is achieved by means of a segmented warp beam of the first of the preceding paragraph, wherein the segmented warp beam has a clamping strip and a fastening device is provided by which the clamping strip can be fixed to Between the side flanges.

A clip is an aid by which the skein of the segmented warp beam can be obtained and fixed over its entire width. With this strip, a help can be obtained by means of which the skein can be withdrawn without forming a bundle of yarns, so that no transverse forces act on the resulting yarn. The hank can be fixed to the strip, for example by compression. Other possibilities can also be imagined. The clip can be secured between the side flanges by means of the fastening device. This has the advantage that the strip can be attached to the skein which has been produced at the end of the segmented warp beam and can be retained in the segmented warp beam, that is to say without interfering with the segmented Other processing of the shaft. This can also be applied when the segmented warp beam rolls along the side flanges as is typical. The clip is positioned within the circumference of the side flanges, that is, the clip does not protrude outward. When the segmented warp beam is placed in the creel, the fastening device only has to be released and the skein can be drawn over its entire width.

The fastening device is preferably constructed as part of the clip. Therefore, the segmented warp beam having the side flanges and the core can have a conventional configuration, which is relatively simple. The clip can be removed from the segmented warp beam together with the fastening device when it is no longer needed.固 When the yarns are pulled away from the segmented warp beam, the fastening device will not interfere.

The fastening device preferably has a length modulation device for the strip. When the strip is to be fastened to the segmented warp beam, the length of the strip is simply elongated so that it can be pressed between the side flanges.

The fastening device is preferably constructed as a clamping force generating device that creates a clamping force between the strip and the side flanges. The clamp bar is held between the side flanges by means of the clamping force, that is to say by friction. Therefore, the processing system is designed to be simple.

Preferably, the clamping force generating device has a spring assembly. The spring assembly can be biased, for example, in the longitudinal direction of the strip, that is, in the width direction of the skein of the segmented warp beam. When the strip is to be fastened to the segmented warp beam, the strip will be compressed somewhat in its longitudinal direction and brought into position between the side flanges before being relaxed. Thus the strip is fixed in the segmented warp beam in a sufficiently secure manner.

The clips are preferably provided with end pieces at both ends, and are made of a rubber elastic material. Such an end piece increases the friction between the strip and the side flanges without requiring a significant effort there.

The object is achieved by a creel as described in the first of the rolls, wherein a conveyor having at least one strip spigot is disposed between the warp beam mount and the creel outlet.

The delivery of the front end of the hank from the segmented warp beam to the inlet of the combination device can also be facilitated by the delivery device. In this regard, the strip only has to be inserted or placed in the strip socket of the delivery device and the delivery device must be activated. The conveyor 嗣 conveys the clip with the skein secured therein from the segmented shaft to the inlet of the combination.

Preferably, the clip socket has two mutually facing pocket members that open toward each other. As a result, the strip is held in its longitudinal direction at its ends and is fixed to the two longitudinal edges of the skein. The conveyor device will pull the clip, whereby the skein can be held by the clips to be aligned. This arrangement is preferably perpendicular to the contour of the yarn of the hank. Thus all the yarns of the hank are uniformly pressed and no disturbing tension is caused in the yarns.

Preferably, the pocket members are attached to the traction members, particularly to the chain, and each has a portion that is movable in a direction from the warp beam mount to the creel exit. Thus, the portions of the traction elements will pass the pocket elements from the segmented shaft to the creel outlet and to the inlet of the combination.

Preferably, the traction elements are constructed as slewing traction elements. A drive that is actuated in one direction is sufficient for the traction elements. When the chain is used as a traction element, the chains can be guided, for example, by two sprocket wheels that are interconnected by a common axis. This shaft can be driven by a motor, such as an electric motor.

Preferably, a plurality of pocket elements are successively disposed in the direction between the warp beam mount and the creel exit, and are successively disposed on The traction elements between the pocket elements are interconnected by transverse braces. When the creel has a plurality of warp beam mounts, a plurality of pocket elements are particularly convenient, enabling the transport device to simultaneously obtain more than one clip and to mount the clips from the warp beam Pull to the creel exit. However, if there is only one warp beam mount, then a plurality of pocket elements are also advantageous because the probability that the pocket elements are in the vicinity of the respective warp beam mount is higher. The transverse braces ensure lateral stabilization of the conveying elements on either side of the strip.

The conveying device is preferably arranged lower than the warp beam mount in the direction of gravity. This has many advantages. In one aspect, the operator does not have to raise the clips with the skeins secured thereto to place the clips in the delivery device. On the other hand, the skeins can be arranged in an area of the floor that can be easily observed so that the pulling process and a later unwinding process can be easily monitored.

The conveying device preferably has a vertical running portion in the region of the creel outlet. It is often necessary to inspect the skein at the exit of the creel. In many cases, the processing of the skein yarns is also desirable. If the conveying device is operated in a vertical manner, the clamping strips having the skein fastened thereto will also be dragged vertically, so that the skein portion in the vertical running portion of the conveying device will also Run vertically.

The invention will be described by way of a preferred embodiment in conjunction with the drawings, in which: Figure 1 shows a segmented warp beam; Figure 2 shows a skein having a clip secured to the top; Figure 3 shows a schematic view of one end of a clip; Figure 4 shows the segmented warp beam in a warp beam mount; Figure 5 shows a A schematic view of one of the creels having a plurality of segmented warp beams; Figure 6 shows a partial view of a conveyor; and Figure 7 shows a plurality of skeins at the shed exit.

Figure 1 shows a segmented warp beam 1 having a core 2 and two side flanges 3, 4 at the ends of the core 2. A skein 5 is wound around the core 2. The hank is composed of a plurality of yarns which are arranged side by side in the longitudinal direction of the core 2 and can be operated in parallel.

A clamp strip 6 will extend parallel to the core 2 . The clips 6 are shown in more detail in Fig. 2, and the yarns are fixedly held. They are juxtaposed to each other at one end in the width direction of the segment warp beam 1, and act on all the yarns in the same manner. In this regard, the clip 6 has a clamp core 7 and a clamp 8. The yarn of the hank 5 is guided around the strip core 7 in a U-shaped manner, and the crucible is fixed to the strip core 7 by the clip 8. This fastening is sufficient to securely hold the yarn of the hank 5 on the strip 6 in a reliable manner.

As can be seen in Figure 1, the strip 6 is secured between the side flanges 3, 4 of the segmented warp beam. In this regard, a securing device 9 as shown in more detail in FIG. 3 will be used as part of the assembly of the strip 6, more specifically as part of the assembly of the strip core 7. At least the length of the clip strip 6 is modulated by the clamping device 7, which can be achieved by the fastening device. In this regard, the clip core has a spring 10 that biases a slider 11 that is displaceably received in The clip core 7 is parallel to the longitudinal direction of the strip 6 in an outward manner. The slider 11 supports the one end piece 12 at its end and is made of a rubber elastic material. The other end of the strip 6 can likewise be provided with one such end piece.

When the skein 5 has been fixed to the clamp 6, as shown in Fig. 2, the slider 11 is pushed into the clamp core 7 against the force of the spring 10, so that the clamp It can be brought into position between the side flanges 4. Then, the sliding piece 11 can be pushed out of the outside of the clamping strip core 7 by the force of the spring 10, so that the clamping strip 6嗣 can be fixedly held on the side flanges 3 in a firm manner. Between 4 and 4. The end piece 12 made of a rubber elastic material ensures proper friction between the strip 6 and the side flanges 3, 4, so that the strip 6 is securely held in the segment. In axis 1.

The clip 6 is positioned within the diameter of the side flanges 3, 4 so that the segmented warp beam 1 can be rolled along the side flanges 3, 4 if desired. Therefore, the strip 6 does not interfere with other treatment of the segmented warp beam 1.

As shown in FIG. 4, when the segmented warp beam 1 is tethered in a warp beam mount 13, the slider 11嗣 is pushed into the clip core 7 again, against the force of the spring 10, And the strip 6 can be released between the side flanges 3, 4, and the skein 5 can be withdrawn from the segmented warp beam 1 at its full width. The lateral stress of the skein, that is, the force that would traverse the longitudinal extent of the yarn of the hank 5, can be avoided. An operator can further dispose of the hank 5 by means of the strip and transfer the hank 5 to a delivery device, which will be described later.

Figure 5 shows schematically a creel 14 in which a plurality of segmented warp beams are provided. The creel, in a manner transverse to its longitudinal direction, that is to say one Two rows of warp beam mounts are provided transversely to the direction in which the skein is pulled away. The creel 14 can also be displaced in a manner transverse to its longitudinal direction, so that the segmented warp beam currently being processed, that is, the warp beam from which the skein is being drawn, can be placed in a The warp yarns are mounted in position and the segmented warp beams can be routed and prepared in another row.

As can be seen in Figure 5, the skeins 5 are pulled away from the segmented warp beam 1 in a downward direction and are pulled to the creel exit under the segmented warp beam 1 in the direction of gravity. The skein 5 here runs under the path 15 covering the skeins 5.

A conveyor 16 that will be described in greater detail by Figure 6 is disposed below the warp beam mounts 13 in the direction of gravity, i.e., also below the lanes 15.

The conveyor 16 has a chain 17 at each of its two longitudinal edges which can be configured to be swivellable. Each chain 17 is guided through a sprocket 18 which can be driven. The chains 17 are interconnected by lateral braces 19 and the like.

A clip socket is constructed here as a pocket member 20 that is tethered between every two adjacent lateral braces. Each pocket component has a receptacle 21. The receptacles 21 of the mutually opposite pocket elements will face each other. Therefore, the pocket elements will open toward each other.

A clip 6 can now be placed in each pair of pocket elements 20. In this regard, the slider 11 can be pushed into the strip core 7 again, such that the strip or, if necessary, the strip core has a length that is less than the spacing between the pocket elements 20 of a pair of pocket elements. . When the spring clamp can be relaxed again and the clamp core 7 is extended, the clamp strip 6 is fixedly received by the conveying device 16 in. If the sprocket 18 is driven, the clips 6, and the skeins 5 secured thereto, and the respective segment warp beams 1 and the like can be pulled to the creel outlet 22. This traction force is applied by a driver (not shown) that is coupled to the sprocket 18. No entry will be required for traction. A deflection element or the like, which can deflect the skeins 5 in a corresponding manner, can be disposed below the tracks 15.

Of course, other traction elements, such as belts, straps or the like, may be used in place of the chain 17 shown.

The conveying device 16, which is shown here only in a schematic manner, by a stand at the creel outlet 22, which is shown in Figure 7, has a vertical running portion, that is, there is one Some will run in the direction of gravity. This "vertical" word is not meant to be considered to be strictly mathematical in nature. However, the skeins 5 are here moved from the bottom to the top by the strips 6, so that the skeins 5 are easily observed by an operator and can be quickly processed if necessary.

A combined device is placed after the creel outlet 22, in which the skeins 5 from all of the segmented warp beams 1 are integrated. Further processing of the hank may also be associated with a combination, such as application of sizing.

With the creel shown, a batch change can be completed in a shorter period of time without any major physical strain. The segmented warp beam 1 provided with the strip 6 must be placed in the warp beam mounts 13. The clips and the skeins 5 secured thereto need only be pulled down until the clips reach the delivery device 16. The clips will be placed in the pocket member 20 there. Once all the strips have been placed in the respective pocket elements 20, the conveyor 16 can be activated without the need for manpower, which will pull all the skeins 5 To the creel outlet 22, from which the skein 5 can be obtained.

The segmented warp beams can here be placed in the warp beam mount 13 where the skein is currently being detached from the row. The segmented warp beams can also be prepared there, and the strips 6 are placed in the transport device 16 at that time. When a batch change is required, the entire creel is simply displaced in a lateral direction.
