Description

Warp beam assembly

Technical Field

The invention relates to a warp-processing textile machine (or called warp-processing textile machine, namely a knottverbeaterendtextilmaschene) with a first warp beam receptacle and a second warp beam receptacle which is different from the first warp beam receptacle.

The invention also relates to a method for operating a warp-processing textile machine having a first warp beam receptacle and a second warp beam receptacle.

Background

In known textile machines, in particular warp knitting machines, a warp beam placed in a beam receptacle is unwound. Once the warp beam is no longer provided with warp yarns, the beam must be replaced. For this purpose, the empty warp beam must be removed from the textile machine, which is achieved only by the size and weight of the warp beam in combination with the lifting device of the lifting heddle (Hubgeschirr). The lifting heddle is laid down against an empty warp beam, whereby the warp beam can be removed with a lifting device (hebevorticichung), for example a crane. The empty warp beam is set aside and the lifting heddle is removed. The lifting heddle can now be placed against a new, full warp beam, whereby the new warp beam can be inserted into the textile machine by means of the lifting device. This process can be accelerated by a plurality of lifting devices and lifting heddles. However, many manipulations (Handgriff) and lifting procedures are necessary. This is very time consuming and labor intensive.

DE 102012205890B 4 describes a beam changing assembly in which three beams are arranged in a rotating device. One beam is unwound while the second beam is in the waiting position and can be replaced by a third beam. By rotation about the axis of the rotating device, the second beam is transferred into position in the first beam, so that an empty beam can be replaced by a full beam.

GB 1111221 a describes a warp beam receptacle device with two warp beam receptacles, in which two warp beams are arranged side by side in the axial direction. One of the two beam receptacles is height-adjustable. The loaded warp beam is placed on the warp beam receiving means by a forklift or the like. By means of this height-adjustable beam receptacle, the axis of the beam is oriented such that the spindle can be pushed through both beams. The warp beams are thereby connected to each other and can be placed as a composite structure in a further processing machine, such as a warp knitting machine.

Disclosure of Invention

The object of the invention is to achieve high productivity.

This object is achieved by the features of claim 1.

In this assembly, the first warp beam receiver and the second warp beam receiver are connected to each other by a guide rail, wherein the open end of the guide rail at the second warp beam receiver is arranged higher in the direction of gravity than the end of the guide rail at the first warp beam receiver. Thereby, a first warp beam can be arranged in the first warp beam housing and a second warp beam can be arranged in the second warp beam housing and prepared there. The beam receptacles are connected to one another by guide rails, the open ends of which are situated higher in the direction of gravity than the ends. In this way, the operator can remove the first warp beam and transfer the second warp beam from the second warp beam receiving section into the first warp beam receiving section without further lifting operations. When unwinding the warp beam which has been placed at this time, a new warp beam can be placed into the second warp beam receiving portion. Thereby, additional lifting processes can be saved during beam replacement, thereby increasing productivity.

Preferably, the second beam receiver has a releasable holding part. The releasable holding portion prevents the warp beam from undesirably moving out of the second warp beam accommodating portion, thereby preventing collision with the warp beam located in the first warp beam accommodating portion. If the first warp beam receptacle is empty, the releasable holding portion may be released or moved in order to release the warp beam. The beam may be transferred into the first beam receptacle. The holding part enables the warp beam to move in a targeted manner and improves reliability.

Preferably, the first transaxle receiving portion has a capturing device. The movement of the warp beam which can be transferred out of the second warp beam receptacle into the first warp beam receptacle is stopped by means of such a catch device. The beam can thus occupy a defined position in which the beam, which is now inserted, can be unwound. The catch device can furthermore have a brake assembly, such as a spring assembly and/or a damper assembly or the like, which brake assembly can brake the movement of the beam gently.

Preferably, the catch device is constructed as part of the bearing housing receptacle. Thereby, the catch device can fulfill a dual purpose by acting as a bearing housing receptacle at the same time. Multiple use saves costs not only in production but also in assembly.

Preferably, the bearing shell receptacle is designed in multiple parts and a part of the bearing shell receptacle is movable. Thereby, a part of the bearing housing can be moved, so that an open bearing housing is formed, from which the warp beam can be taken out or put in. The exchange of the beam can be easily designed by means of such an assembly.

Preferably, a beam is arranged in the second beam assembly, the beam having a first roller diameter and a second roller diameter, wherein the second roller diameter is different from the first roller diameter, the guide rail having a first section and a second section, wherein the second section is different from the first section and the first roller diameter interacts with the first section and the second roller diameter interacts with the second section. Furthermore, the first roller diameter may have a beam carrying tube and the second roller diameter may have a bearing assembly of a beam. The first roller diameter initially interacts with the first section of the guide rail from the second beam assembly. If the beam is moved in a rolling movement starting from the second beam receptacle, this movement can be described by a certain angular velocity. The translational motion of the beam is derived from the angular velocity and the diameter. At the same angular velocity, a larger diameter achieves a larger translational movement than a smaller diameter. If the beam is moved with its first roll diameter (large roll diameter) in the first section, a greater translational speed is obtained than if the beam is moved with its second roll diameter (small roll diameter) in the second section at the same angular speed. Thus reducing and/or arresting the translational movement. The forces to be captured are thus smaller, so that the capture device can be dimensioned smaller.

Preferably, the second roller diameter of the beam is arranged in the catching device into the unwinding position. The warp beam is reliably supported and can be unwound directly from the first warp beam receptacle. Further movement of the beam is omitted, which improves productivity.

This object is achieved in a method of the type mentioned at the outset in that the warp beam is transferred from the second warp beam receptacle along the guide rail in a gravity-driven manner into the first warp beam receptacle.

In this method, the shaft is transferred from the second warp beam receptacle into the first warp beam receptacle along the guide rail by means of gravity drive. Additional peripheral devices, such as drives, gear mechanisms or the like, can thus be dispensed with, which keeps the costs low. Furthermore, since the warp beam can be rapidly replaced by a single operator, the down time of the textile machine is reduced, whereby productivity can be improved.

Preferably, the releasable holding portion fixes the warp beam in the second warp beam receiving portion. Undesired movements of the warp beam in the second warp beam receptacle are prevented by the holding portion, which improves the operational reliability. The holding portion may be arranged in different positions, for example in a holding position or a release position.

Preferably, the beam is released by movement of the holding portion. By transferring the holding portion from the holding position into the releasing position, the warp beam can be released. As a result, the warp beam can be transferred into the first warp beam receptacle as soon as it is empty. So that another beam in the store can be placed in the second beam receptacle.

Preferably, the guide rail has two sections, wherein the beam is braked in its movement in the second section. The braking in the second section reduces the speed of the beam, so that the force to be absorbed by the catch device can be reduced.

Preferably, the translational movement of the beam is braked by a change of support from a first roller diameter of the beam to a second roller diameter of the beam. If the beam reaches a certain angular velocity during its movement, the peripheral velocity can be determined from this angular velocity in combination with the diameter over which the beam rolls. Furthermore, the speed of the translational movement can be determined from this peripheral speed. If the diameter is reduced with the same angular velocity, the peripheral velocity of the beam and thus the velocity of the translational movement also decreases. The warp beam is braked accordingly. By such an arrangement, additional braking means can be dispensed with.

Preferably, the catch means surrounds the second diameter in the unwound position. By this arrangement, an additional beam receiving device is dispensed with. This first warp beam receptacle can be arranged in the same position as the previous warp beam receptacle in the textile machine. Thus, a modification of the textile machine, in particular of the warp knitting machine, is dispensed with.

Drawings

The invention is described below with the aid of preferred embodiments in connection with the attached drawings. Wherein:

figure 1 shows a side view of a first warp beam housing and a second warp beam housing;

fig. 2 shows a cross-sectional view along the plane a-a of fig. 1.

Detailed Description

Fig. 1 shows a first warp beam receptacle 1 and a second warp beam receptacle 2 in a side view, wherein the second warp beam receptacle 2 is arranged higher in the direction of gravity than the first warp beam receptacle 1 at a guide rail 3. The first crankshaft receiver 1 has a catch 4, which can be designed as a bearing housing receiver. The second beam receiver 2 furthermore has a releasable retaining part 5, which can be arranged in a first position (retaining position) or in a second position (release position) which is different from the first position. The guide rail 3 has a first section 6 and a second section 7. The first section 6 is arranged in the region of the second warp beam receptacle 2 and the second section 7 is arranged in the region of the first warp beam receptacle 1, wherein the two

sections

6, 7 at least partially overlap.

Fig. 2 is a sectional view taken along the plane a-a of fig. 1. The beam 8 has two

different roll diameters

9,10, a first roll diameter 9 and a second roll diameter 10. The first roller diameter 9 interacts with the first section 6 of the guide rail 3 and the second roller diameter 10 interacts with the second section 7 of the guide rail 3. In the present embodiment, the first roller diameter 9 is larger than the second roller diameter 10.

The open end of the guide rail 3 is arranged in the region of the second beam receptacle 2. Which is located higher than the end of the guide rail 3 in the direction of gravity. The guide rail 3 can be cast as a rail, profile, profiled element (form) or the like. Furthermore, the guide rail 3 can have another embodiment, such as a parabola or the like, in addition to the linear embodiment. The extension of the guide rail 3 is, however, intended to be such that the warp beam 8 can be transferred into the first warp beam receptacle 1 by gravity-driven release from the second warp beam receptacle 2.

The holding portion 5 holds the warp beam 8 in a waiting position. The beam 8 can be released by a movement of the holding part 5 from the first position (holding position) into the second position (releasing position). Thereby, beam 8 can move along guide rail 3 and be transferred from second beam assembly 2 to first beam assembly 1.

The warp beam 8 is moved in the direction of the first warp beam receptacle 1, starting from the second warp beam receptacle 2, in a manner driven by gravity. The warp beam 8 is first located in the first section 6, with which the first roller diameter 9 interacts. The warp beam 8 rolls along the guide rail 3 andto a certain angular velocity (T)_out) From this angular velocity, in combination with the roller diameter 9, the translational movement (arrow) of the beam 8 can be determined. The first section 6 and the second section 7 overlap in a certain area. From this region, the second roll diameter 10 and the second section 7 cooperate. Since the second roller diameter 10 is smaller than the first roller diameter 9 in this embodiment, the movement of the beam changes. Because, as already described above, the translational movement depends on the angular velocity and the roller diameter. If the angular velocity remains constant and the

roller diameters

9,10 decrease when transitioning from the first section 6 to the second section 7, the translational movement of the beam 8 correspondingly decreases, i.e. is braked. The catching device 4 can thus intercept smaller forces of the moving beam 8.

Furthermore, the beam 8 is positioned by the catch 4 in such a way that it can be unwound in this position (unwinding position). For this purpose, the warp beam 8 is arranged in a bearing housing of the catch device 4. The bearing housing can be designed to be separate, so that the insertion and removal of the beam 8 can be easily performed. In the catch 4 (or bearing shell), the second roller diameter 10 is at least temporarily arranged for machining (Abarbeitung) of the beam 8.

The replacement of the warp beam 8 of the first warp beam accommodating portion 1 is described below. Here, an empty first warp beam 8 is unwound from the first warp beam receptacle 1 and a full second warp beam 8 is wound up for standby in the second warp beam receptacle 2.

In order to remove a warp beam 8 from the first warp beam receptacle 1, the catch device 4 or the bearing shell is brought into a removal position, so that the unwound warp beam 8 can be removed from the first warp beam receptacle 1. As soon as the unwound warp beam 8 is removed from the first warp beam receptacle 1 and the region of the first warp beam receptacle 1 is released, the second warp beam 8 can be transferred from the second warp beam receptacle 2 into the first warp beam receptacle 1. For this purpose, the holding part 5 is transferred from the holding position into the release position, whereby the second warp beam 8 is released in the second warp beam receptacle 2. The second beam 8 moves along the guide rail 3 in the direction of the first beam receptacle 1 in a gravity-driven manner. The movement may be by scrolling, sliding, or a combination of scrolling and sliding.

Once the second beam 8 is released, it moves rolling along the guide 3 in this embodiment. The first rolling diameter 9 is in contact with the first section 6. In the region of the first spindle receptacle 1, the contact of the first roller diameter 9 with the first section 6 is released and a contact is produced between the second roller diameter 10 and the second section 7 of the guide rail 3. The second roll diameter 10 of the beam 8 interacts with the second section 7. The rolling motion is accompanied by a certain angular velocity. The angular velocity and the

roll diameters

9,10 give the translational movement velocity. If the

roll diameters

9,10 are changed from the first roll diameter 9 to the second roll diameter 10 with the angular speed of the beam 8 remaining unchanged, the speed of the translatory movement of the beam 8 is changed. In the present embodiment, the first roller diameter 8 is larger than the

second roller diameters

9,10, whereby the translational movement of the beam 8 is braked.

Finally, the catching device 4 completely intercepts the warp beam 8 and transfers the warp beam 8 into the unwinding position, in which the warp beam 8 can be unwound. The second roller diameter 10 is arranged in the catch device 4 or bearing shell in the unwinding position.

In the interim time of processing the warp beam 8, a new warp beam 8 may be arranged into the second warp beam housing 2. For this purpose, the holding part 5 is brought into the holding position. The process may be restarted.

The described beam assembly may find application, for example, at warp knitting machines. Alternatively, the described beam assembly can also be used at other textile machines working with beam 8 or at machines equipped with warp yarns. Here, the empty warp beam 8 can be located in the second warp beam receptacle 2, while the warp beam 8 is wound by a warp beam winding machine. After the warp beam 8 is wound, an empty warp beam 8 can be transferred into the first warp beam receptacle 1 as described above.
