Description

Warp beam assembly

Technical Field

The present invention relates to a warp processing textile machine (or called warp processing textile machine, kettverarbeitende Textilmaschine) with a first warp beam housing and a second warp beam housing different from the first warp beam housing.

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

Background

In known textile machines, in particular warp knitting machines, the warp beam placed in the warp beam receptacle is unwound. Once there are no warp yarns on the beam, the beam must be replaced. For this purpose, the empty beam must be removed from the textile machine, since the size and weight of the beam can only be achieved by means of a lifting device in combination with a lifting heddle (hubgischirr). The lifting heddles are placed against the empty beam, whereby the beam can be removed with a lifting device (e.g. a crane). The empty beam is set aside and the lifting heddle is removed. In this case, the lifting heddles can be placed against a new, full beam, whereby the new beam can be placed into the textile machine by means of the lifting device. The process can be accelerated by a plurality of lifting devices and lifting heddles. However, many maneuvers (Handgriff) and lifting processes are necessary. This is very time consuming and labor intensive.

DE 1020110205890 B4 describes a beam changing assembly in which three beams are arranged in a rotating device. In this case, one beam is unwound, while the second beam is in the waiting position and the third beam can be replaced. By rotation about the axis of the rotation device, the second beam is transferred into position in the first beam, so that the empty beam can be replaced by a full beam.

GB 1111221A describes a warp beam receiver arrangement with two warp beam receivers, wherein the two warp beams are arranged side by side in the axial direction. One of the two beam receiving portions is height-adjustable. The loaded beam is placed onto the beam receiver means by a forklift or the like. By means of this height-adjustable beam receptacle, the axes of the beams are oriented such that the spindles can be pushed through both beams. The beams are thereby connected to each other and can be placed as a composite structure into a further processing machine, such as a warp knitting machine.

Disclosure of Invention

The purpose of the present invention is to achieve high productivity.

This object is achieved by the features described below.

In such an assembly, the first warp beam accommodation and the second warp beam accommodation are connected to each other by means of a rail, wherein the beginning of the rail at the second warp beam accommodation is arranged higher than the end of the rail at the first warp beam accommodation in the direction of gravity. Thereby, the first beam may be arranged in the first beam accommodation and the second beam may be arranged in the second beam accommodation and prepared there. The beam receptacles are connected to one another by a guide rail, wherein the beginning of the guide rail is situated higher than the end in the direction of gravity. Thereby, the operator can take out the first beam and transfer the second beam from the second beam accommodation into the first beam accommodation without further lifting operations. When unwinding the warp beam that has been put in at this time, a new warp beam can be put into the second warp beam accommodation. Thereby, additional lifting processes can be saved during beam replacement, thereby improving productivity.

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

Preferably, the first shaft receptacle has a capturing device. The movement of the warp beam which can be transferred from the second warp beam accommodation into the first warp beam accommodation is stopped by means of such a catching device. The beam can thus occupy a defined position in which the beam that is now put in can be unwound. The catch device may furthermore have a braking assembly, such as a spring assembly and/or a damper assembly or the like, which may gently brake the movement of the beam.

Preferably, the catch device is configured as part of the bearing housing receptacle. Thus, the capturing device can fulfill a dual purpose by acting as a bearing housing receptacle at the same time. Multiple uses save costs not only in production but also in assembly.

Preferably, the bearing housing receptacle is constructed in multiple pieces, and a portion of the bearing housing receptacle is movable. Thereby, a part of the bearing housing can be moved, thereby forming an open bearing housing, from which the beam can be removed or placed in. Replacement of the beam can be easily designed by 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 cooperates with the first section, and the second roller diameter cooperates with the second section. Further, the first roller diameter may have a beam carrying tube and the second roller diameter may have a bearing assembly of the beam. The first roller diameter, starting from the second beam assembly, first interacts with the first section of the guide rail. If the beam is moved in a rolling motion starting from the second beam receptacle, this motion can be described by a certain angular velocity. The translational movement of the beam is derived from the angular velocity and the diameter. With the same angular velocity, a larger diameter enables a larger translational movement than a smaller diameter. If the beam moves in the first section with its first roll diameter (large roll diameter), a greater translation speed is obtained than if the beam moves in the second section with its second roll diameter (small roll diameter) at the same angular speed. Thus reducing and/or braking the translational movement. The forces to be intercepted are thus smaller, whereby the capturing device can be dimensioned smaller.

Preferably, the second roller diameter of the beam is arranged in the capturing 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 increases productivity.

In a method of the type mentioned at the beginning, this object is achieved in that the beam is transferred from the second beam receiver into the first beam receiver along the guide rail in a gravity-driven manner.

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

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

Preferably, the warp beam is released by movement of the holding portion. By transferring the holding part from the holding position into the release position, the warp beam can be released. Thereby, once the first warp beam accommodation is empty, the warp beam can be transferred thereto. Thus, a further beam in the warehouse can be inserted into the second beam receptacle.

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

Preferably, the translation movement of the beam is braked by a transition from a first roller diameter of the beam to a support on a second roller diameter of the beam. If the beam reaches a certain angular velocity during its movement, its 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 speed of the beam and thus the speed of the translational movement is also reduced. The beam is braked accordingly. By this arrangement, additional braking means can be dispensed with.

Preferably, the catch means encloses the second diameter in the unwinding position. With this arrangement, a further warp beam receiver device is dispensed with. The first warp beam receptacle may be arranged in the same position as the warp beam receptacle in the previous textile machine. Thus, retrofitting of textile machines, in particular warp knitting machines, is dispensed with.

Drawings

The invention is described below with the aid of preferred embodiments in connection with the accompanying drawings. In which:

fig. 1 shows a side view of a first warp beam accommodation and a second warp beam accommodation;

figure 2 shows a cross-section along the A-A plane of figure 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 than the first warp beam receptacle 1 at the guide rail 3 in the direction of gravity. The first shaft receptacle 1 has a catch device 4, which can be configured as a bearing housing receptacle. The second beam holder 2 furthermore has a releasable holding part 5 which can be arranged in a first position (holding 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 accommodation 2 and the second section 7 is arranged in the region of the first warp beam accommodation 1, wherein the two sections 6, 7 at least partially overlap.

Fig. 2 is a cross-sectional view taken along the A-A plane 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 cooperates with the first section 6 of the guide rail 3 and the second roller diameter 10 cooperates 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 beginning 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 rail 3 in the direction of gravity. The guide rail 3 can be cast here as a rail, profile, profiled element (form) or the like. Furthermore, the guide rail 3 can have other embodiments than linear embodiments, such as parabolic or the like. However, the extension of the guide rail 3 is intended to be such that the beam 8 can be transferred from the second beam receiver 2 into the first beam receiver 1 in a gravity-driven manner by releasing it.

The holding portion 5 holds the beam 8 in the waiting position. The warp 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 moves from the second warp beam holder 2 in the direction of the first warp beam holder 1 in a gravity-driven manner. In this case, the beam 8 is initially located in the first section 6, with which the first roller diameter 9 cooperates. The beam 8 rolls along the guide rail 3 and reaches 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 roller 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 is changed. 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 during the transition from the first section 6 to the second section 7, the translational movement of the beam 8 correspondingly decreases, i.e. is braked. Thus, the capturing device 4 may capture less force of the moving beam 8.

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

The replacement of the warp beam 8 of the first warp beam accommodation 1 is described below. Here, the empty first beam 8 is unwound in the first beam receptacle 1, and the full second beam 8 is wound in the second beam receptacle 2 for standby.

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

Once the second warp beam 8 is released, it moves in this embodiment in a rolling manner along the guide rail 3. The first rolling diameter 9 is in contact with the first section 6. In the region of the first shaft 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 roller diameter 10 of the beam 8 cooperates with the second section 7. The scrolling motion is accompanied by a certain angular velocity. This angular velocity gives the translational movement velocity with the roller diameters 9, 10. If the roller diameters 9,10 are changed from the first roller diameter 9 to the second roller diameter 10 with the angular velocity of the beam 8 remaining unchanged, the translational movement velocity 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 capturing device 4 intercepts the beam 8 completely and transfers the beam 8 into an unwinding position in which the beam 8 can be unwound. The second roller diameter 10 is arranged in the unwinding position in the catching device 4 or the bearing housing.

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

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