Description

DEVICE FOR REMOVING A TRAIN-FORMED PRODUCT

FROM A WEAVING MACHINE

The invention relates to a device for withdrawing a sheet-like product from a loom.

Devices for the withdrawal of sheet-like products of looms are known. They are always used when web-shaped products, in particular fabrics

be produced continuously or in sections, the produced sheet-like products are wound after deduction of the weaving machine to supply them to a further processing process.

From DE 10 2015 222 142 B3 a device for the production and withdrawal of a web-shaped product is known. To remove the webformigen product of the

Weaving machine serve two terminal carrier with clamps, wherein further drive means are provided, through which the terminal support in the withdrawal direction of the web-shaped

Product driven back and forth. By the reciprocating movement of the terminal support in conjunction with the controlled opening and closing of the terminals takes place the removal of the web-shaped product, wherein a tension is applied to the web-shaped product by driving the drive means for the terminal support with the terminals. According to this known device, the web-shaped product is manufactured with main sections and auxiliary sections. The auxiliary sections serve the purpose of the clamps at these sections gripping the sheet-like product, that is to say opening and closing the clamps only during the periods of production of the sheet-like product in which an auxiliary section for holding the sheet-like product is produced.

The object underlying the invention is now directed to produce a device for the withdrawal of a web-form product from a loom, which is for thick goods, especially for so-called 3D-goods, for example, for multi-layer fabric, usable, said means of this device a slack of the finished produced Section of the web-shaped product should be minimized or avoided altogether. This object is achieved by a device for withdrawing a sheet-like product from a loom with the features of claim 1. Advantageous developments are defined in the dependent claims. The inventive device for the withdrawal of a sheet-like product of a

Weaving machine has at least one terminal support, which has clamps for the web-shaped product, a support frame device on which the clamping support is guided, and a drive means, by which the terminal support in the withdrawal direction of the sheet-like product of the weaving machine in a range of motion is reciprocally driven , The trigger is preferably horizontal. In the context of this invention, "sheet-like product" is to be understood as meaning, in particular, three-dimensional web-shaped products, which are preferably multi-layered fabrics

Terminal support according to the invention is designed so that it can hold the sheet-like product within the range of movement of the terminal carrier clamping. According to the invention, a support system for the sheet-like product is provided at least between a device side facing the weaving machine and the terminal support within the support frame device. This avoids unduly large sag between the device side and the terminal support. The web-shaped product can be detected by the terminal carrier on the weaving machine and can be guided in its withdrawal direction substantially at production speed. Above all, the support system serves to be able to remove thick, but to some extent flexible, sheet-like products from the weaving machine without its sagging device being able to pull off the sheet-like product. In three-dimensional, for example, multilayer,

namely formed rail-shaped products, namely the risk that due to its own weight, an unacceptably large sag arises, through which the inner structures of the three-dimensionally formed sheet-like product are deformed, which is a

Quality loss.

Thanks to the support system, the web-shaped product is supported in such a way that there is only a slight sag of the product. As very thick or multi-ply web-shaped products here products with a thickness of about 6 to 20 mm, possibly even in the range of 40 to 100 mm or above referred to. Such three-dimensionally formed sheet-like products can no longer be wound on a cloth or a winding roller. This would be trained in three dimensions

sheetlike product in its internal structure damaged and deformed. Therefore Very thick web-shaped products generally have to be removed horizontally from the weaving machine, namely in the warp direction, so that the individual layers or the individual threads forming the three-dimensional structure are not displaced or deformed. Depending on the use, the product sections to be held and supported within the device may be relatively long, so avoiding slack is of paramount importance.

The possibly resulting sag of the web-shaped product portion is of the width of the device, d. H. from the width of the support frame device, from the tension of the terminal support, which pulls the product section from the loom into the device for deduction, depending on the length of the section produced and the basis weight of the web-shaped product. It has now been found that, by means of an inventive support system, the product section can be kept level in the device in such a way that the fabric quality in the width and longitudinal directions is not impaired by unacceptably high sag.

Preferably, a second terminal support is provided between the device side, which faces away from the loom, and the first terminal support. The sheet-like product is at least temporarily clamped by the first and the second clamp carrier. This means that the sheet-like product is clamped at its leading end and at its trailing end, which faces the device side of the loom, at least temporarily also clamped.

Preferably, the support system is in the form of tensioning cables or spine chains or tensioning cables and spine chains in combination. The

Support system is movable at a speed corresponding to the production speed of the web-shaped product in the withdrawal direction. By that

Support system is movable at a speed corresponding to the production speed of the product section, it ensures that it is on the

Support system does not come to unwanted, possibly the product damaging friction.

According to one embodiment of the invention, the first or possibly the second terminal carrier drives the tensioning cables and / or the back-rigid chains, wherein preferably the tensioning cables can be wound into a rope winder or the back-rigid chains can be pushed into a chain storage or are deductible from these. The rope winder and / or the chain storage serve to the support system during the reciprocating movement of the or

Wind up terminal support or handle from such a memory. The advantage of working with a take-up or unwind memory is u. a. also in that the working length of the device is easily adaptable to changed desired lengths of a product section.

Under back-stiff chains or so-called push chains are understood such chains, which arranged in several succession, by chain pins

connected chain links are formed, which are designed such that a kinking of the chain links about the axis of the chain pins in one direction is possible, but in the other direction, a kink over a straight arrangement of the chain links is blocked out. Embodiments of such chains are e.g. EP 1744079 A1, the

DE 20209957 U1 or DE 10137939 A1.

These chains can thus be pushed in the direction of production as a support below the product, without leaving their supporting the product section support level.

Preferably, the tension cables or the backrest chains are in the longitudinal direction of the

Product section and movable in parallel. This means that over the width of the support frame device, within which the product section is guided by means of the terminal support, the clamping side and / or the back-stiffened chains are arranged side by side so that a support plane is formed, namely the support plane, which provides a uniform support guarantees the product section, so that it is feasible largely sag-free within the device, and that no slack especially in the longitudinal direction, which corresponds to the withdrawal direction.

Preferably, in the region between the device side, which faces the weaving machine, and the first or, if present, the second terminal carrier, the support system is provided with at least two backstacked chains whose movement is synchronized with one another. The provision of only two back-rigid chains is useful above all if on the one hand the effort for the support system to be kept within limits, on the other hand, the product section a certain

Having inherent rigidity, so that the product section between the two backstep chains, in which an immediate support of the tissue section is not given, not or at least not significantly sags.

Preferably, each terminal support is provided with a respective upper and a lower terminal block as a terminal, which are mounted within the terminal support on Klemmleistenkörpern, wherein the tensioning cables and / or the back-rigid chains or the push chains are guided through openings in the respective lower clamping bar bodies. It makes sense that the openings have a size such that a required clamping stroke of the respective lower clamping bar for a clamping of the product section is executable without the tensioning cables and / or the back-rigid chains are deflected from their support level.

In principle, instead of clamping strips, hook-shaped or needle-shaped elements can also be used in order to fix the sheet-like product to the terminal carriers. For example, strips with attached hook-shaped elements or with

Needles may be attached to the upper and / or lower terminal supports. When executing the vertical clamp stroke, the hooks or needles dip into the sheet-shaped product. In order to avoid a violation of the base material, it is necessary in these cases to provide the web-shaped product at intervals with auxiliary sections, which are later cut off.

According to a further embodiment, the tensioning cables and / or the back-rigid chains are formed as endless elements. In such a case eliminates the aforementioned unwinding or unwinding devices. Instead, deflection elements, such as pulleys or sprockets, are provided to redirect the tensioning cables or chains within the device from the withdrawal direction to the opposite direction.

This leads to a structurally simplified design, which can be useful with always the same length of the product sections to be produced. Further preferably, the tensioning cables and / or back-stiff chains can be wound up and unwound with the movement of the first or possibly the second terminal carrier in the withdrawal direction of the web-shaped product. For this purpose, a take-up or unwinding unit is integrated in the respective terminal carrier, so that this or the entire device can be made compact. Further preferably, the support system has one within the

Supporting frame device arranged lifting table, which from a retracted position in a product section on the underside of which supporting, the sag substantially avoidable supporting position is movable. It can also be provided from a plurality of lifting tables existing Hubtischsystem.

In a further embodiment of the invention, the support system, which supports the web-shaped product on its underside between the first or possibly the second terminal carrier and the loom, a scissor linkage system with z. B. idlers, slide rails, sliding plates, tension cables. The advantage of such a scissor linkage system is above all that the support length for the product section to be supported in the device is relatively easily adaptable to different lengths of the product section. The support rollers, slide rails, sliding plates or tension cables are arranged in the scissor linkage system in such a way that their respective towards the one to be supported

Product section facing surfaces form the support level. The

Scissor linkage system is movable from its extended, stretched, in its retracted, "compressed" state in the aspect ratio of preferably about 3: 1. With a length of the device of preferably 6 m, the compressed length is about 2 m Therefore, it can continue to be provided for

Scissor linkage system can be moved down into an area below the terminal support, which can be realized in particular by means of a guide rail in the manner of a slotted guide.

Figure 5 shows a side view in a schematic representation of an apparatus for withdrawing the web-shaped product 20 according to the prior art. Figure 5 shows a sectional view of the device in its longitudinal direction. The device comprises two terminal supports 1, 2 a support frame 3, drive spindles for the two terminal support 16, covers 17 and a weaving machine 19. Between the terminal support 1 and the terminal support 2 is the produced sheet-like Ware, ie the web-shaped product 20 located and has a sag 18 (f ₂ ) in the middle. The device according to the present invention avoids or limits this slack. Thus, a slack f1 between the loom 19 and the trigger device is avoided, it is also advantageous if the

Deduction device is brought as close as possible to the loom 19.

FIG. 1 shows a perspective view of a first embodiment of the device according to the invention. The device is facing with her the weaving machine

Device side 4 in the withdrawal direction 8 so to speak next to the loom, not shown, or arranged adjacent to this. A support frame device 3 carries on the example of Figure 1 a first terminal support 1 and a second terminal support 2, the latter having a chain memory 9, in which provided as a support system 5 back-rigid chains 7 are arranged in the form of push chains. The number of back-rigid chains 7, in the present example, four such chains 7 are shown, depends on the width of the web-shaped product produced by the loom and on its inherent rigidity. The second terminal support 2 is associated with a chain memory 9, and the terminal support are intended to take the sheet-like product to clamp and with

Production speed within the device to move to its deduction. The supporting length of the support system 5 corresponds to the length of the manufactured sheet-like product to the second terminal support 2; the rest of the

Support system is in the memory, in the training shown here as a rigid chain 7 wound in the chain memory 9 Thus, the rear part of the device, in Figure 1, the lower left part, for maintenance and operators to the

Chain store 9 freely accessible. On both sides of the support frame device 3 are

Spindles 16 are provided which reciprocate the clamping devices 1, 2 via correspondingly assigned drives (not shown) within the supporting frame device. In addition to the spindle 16, a cable drag chain 15 is arranged, which ensures a supply of the corresponding supply lines to the drives of the terminal carrier. The back-rigid chains have a distance from each other, which prevents sagging of the web-shaped product due to an existing own weight in the width direction.

When the web-shaped product 20 is produced by the loom, takes or

the second terminal support 2 clamps the leading leading edge of the sheet-like

Product and moved with the production speed for the web-shaped product selbiges in a clamping manner over the desired length of the section to be produced. During the withdrawal, the produced web-shaped product 20 is supported on the backstifte chains 7 substantially without sag. After the produced length of a first section of the web-shaped product 20 is reached, the first takes hold

Clamp support 1, the leading edge of the next produced sheet-like product section and maintains the tension between the trigger and the loom. After gripping the web-shaped product section through the first terminal support, the clamp of the second terminal support 2 can be opened. Subsequently, the second terminal support 2 moves back from the rear of the discharge device and the produced web-shaped product section can be removed from the device by the operator. The back-end chains 7 are passed through openings 13 in the terminal carrier 1 and 2. They are wound up again in the chain stores 9 when the second terminal carrier moves out of the rear area of the withdrawal device according to the invention in the direction of the weaving machine. As soon as the opened second terminal support 2 has reached the first terminal support 1 on its way counter to the withdrawal direction 8, the first terminal support 1 detected by the first terminal support is reached

Pass the product section to the second terminal support by appropriate control of the terminals and drives, and the process described above begins again.

FIG. 2 shows a perspective detail view of an upper clamping strip 10 and a lower clamping strip 11 for the first terminal carrier 1 and the second terminal carrier 2, respectively. The back-rigid chains 7 are passed through openings 13 through the terminal block body 12 of the terminal carrier 1 and 2 and are inserted into the chain memory 9 and wound there. With corresponding opposite movement, the chains are in the

Chain store again handled. In the present presentation has the second

Terminal carrier 2, the terminal strips 10, 1 1 almost closed, while the first

Terminal carrier 1, the upper terminal block 10 and the lower terminal block 1 1 are wide open. In the area of the clamping bars 10, 11, the web-shaped product 20 produced by the first one is essentially free from sagging, resting on the backstacked chains 7

Terminal support 1 and the second terminal support 2 so far passed that the corresponding terminal strips 10, 1 1 for clamping of the web-shaped product 20 can be effective. In Figure 3a is a principal view in the direction of the deduction, d. H. shown in the longitudinal direction of the device for withdrawal of the web-shaped product, in which between the upper terminal strip 10 and the lower terminal block 1 1, the web-shaped product 20 is supported or clamped supportive. Both the upper terminal strip 10 and the lower terminal block 10 are divided into individual segments. As in the production of the

three-dimensional web-shaped product 20 certain differences in the thickness produced can occur or can be produced in a targeted manner is thus ensured that no slip or insufficient clamping occurs at any point on the width of the web-shaped product to be clamped on the respective terminal carrier. In the segments which form the lower terminal block 1 1, corresponding openings 13 are provided in accordance with the distance to support the web-shaped product by the back-rigid chains 7 through which the back-rigid chains are guided, so that a collision with the product to be clamped 20 and the terminal strips is avoided. The illustrated first terminal carrier is guided over guideways 24 provided on both sides. The web-like product to be clamped extends in the plane 25. In addition, the spindles are shown 16, which ensure the safe and reliable and accurate drive the movement of the respective terminal carrier 1, 2.

FIG. 3b shows a further detailed view in perspective view of the clamping region of the first terminal carrier 1 and of the second terminal carrier 2. By way of example only a back-rigid chain 7 is shown, for which below the actual effective between the upper terminal block 10 and the lower terminal block 1 1 clamping area an opening 13 is provided in the respective terminal block body 12 through which the back-rigid chain 7 is guided. , The openings 13 for carrying the back-rigid chains 7 are incorporated in the terminal block body 12. Above the back-rigid chains 7 immediately before and after the terminal strips 10, 1 1 bearing surfaces 29 are provided on soft the web-shaped product 20 rests at about the same level with the immediate clamping surface of the terminal strips 10, 1 1. Between these bearing surfaces 29 and the support level on the upper side of the backstiffened chain there is a height difference that is necessary for the back stiffener chains 7 can be guided by the terminal block body 12, below the immediate clamping surfaces of the terminal strips 10, 1 1, and thus on the other a clamping of the web-shaped product can take place at the designated locations for the purpose of its movement. Shown are the two lower ones

Terminal block body 12 of the first and second terminal support, wherein the left in Figure 3 shown terminal block body of the first terminal support with its opening 13 has moved down far enough that the back-rigid chain 7 just slides with its top at the top of the opening 13. On the other hand, the terminal block body 12 of the second terminal carrier shown on the right in FIG. 3 has moved upwards so far that the bearing surface 29 is substantially aligned with the immediate clamping surface of the upper terminal strip 10 and the lower terminal strip 11.

FIG. 4 shows a further exemplary embodiment in which

Supporting system a number of side by side substantially parallel tensioning cables 6 is provided. The tension cables 6 extend within the

Device according to the invention for the withdrawal of the web-shaped product 20 between the

Support frame device 3 in the longitudinal direction. The tensioning cables 6 are dimensioned so that they can cover the area between the terminal supports 1, 2 exciting with such a voltage that when the transported web-shaped product 20 or product section, the tensioning cables 6 do not or only insignificantly sag. The tension cables 6 are attached to a cable winder 30 in the front of the device 4 and become substantially with movement of the second terminal support 2 with

Production speed of the web-shaped product 20 deducted from the rope winder 30, so that their deducted length corresponds to the just produced length of the sheet-like product to the second terminal support. The ropes are arranged at a substantially constant distance from each other. Depending on the width produced the web-shaped product 20 can be unlatched to support unneeded tension cables, so that only so much juxtaposed tensioning cables 6 are subtracted by the second terminal support 2 exciting from the cable winder 30, as the width of the produced web-shaped product 20 to avoid a slack of the product requires. From Figure 4 it can be seen that the web-shaped product 20 is produced by the weaving machine 19 and is transferred to the apparatus for withdrawing the web-shaped product. In a schematic representation, the two sides of the support frame device 3 are shown, in each of which corresponding spindles 16 are arranged, on which the terminal supports 1, 2 are guided in stock and movable.

FIG. 6 a shows a further exemplary embodiment according to the invention, in which the support system 5 is formed by two support roller tracks 23 arranged next to one another. The web-shaped product 20 passes through the device according to FIG. 6a in the withdrawal direction from right to left. On the right side at the inlet of the web-shaped product 20 in the device for the withdrawal of the sheet-like product is at the

Support frame device 3 a chain memory 9 is provided. At the outlet end of the device according to the invention, the second terminal support 2 is shown, on which the other end of the chains 7 is fixed, on which the support rollers 23 are mounted. Depending on

Stiffness of the produced sheet-shaped product 20, the distance between the side by side in parallel alignment arranged support roller tracks can be adjusted.

In Figure 6b, the embodiment of Figure 6a is shown in an enlarged view. It can be seen that the individual support rollers 21 are connected on both sides in each case with a back-rigid chain or push chain, so that the support system 5 according to this embodiment also with production speed of

web-shaped product 20 can be transported through the device for deduction of the web-shaped product, without the same sags, because this

Support system 5 is formed with the support rollers 21 so that the inherent rigidity Bending at the not directly supported by support rollers 21 spaces between the support rollers substantially prevented.

In Figure 6c, the push chains and two support rollers 21 are shown in a further enlarged view. It is clear that at the thrust chain roller bearing 22 and two adjacent support rollers 21 are arranged at a distance from each other, which the

Four times the axial distance between the roller bearings 22 corresponds. Depending on the rigidity of the web-shaped product 20, the distance of the support rollers 21 can be varied so that in the narrowest case each support roller bearing 22 is associated with a support roller 21.

Figure 7a shows a schematic representation of a side of the device according to the invention for the withdrawal of the web-shaped product 20, namely the embodiment according to Figures 1 -3 with back-rigid chains 7 in the form of push chains. One possible embodiment of such a push chain 7 is shown in FIG. 7b. This sees each other alternating

Chain links 7.1, 7.2, 7.3 before, which are each connected to each other via a chain link. Each chain link includes a chain pin 7.4. The chain links 7.1 and 7.2 have at their ends in the chain running direction supporting contours. The arrangement of the Abstützkonturen is designed so that the rotation of the chain links about the axis of the chain pin 7.4. is prevented by a concern of adjacent Abstützkonturen in one of two possible directions of rotation. The chain can thus absorb forces in a direction perpendicular to the chain pins and perpendicular to the longitudinal axis of the chain without buckling. This property is also referred to as "back stiff. Chain links and Abstützkonturen are shown here by way of example. In order to achieve the described properties, other forms and designs of such push chains are possible - for example, according to the above-mentioned prior art.

These shear chains form a corresponding support area for the produced web-shaped product 20. At one end, these back-rigid chains 7 are feasible in their respective associated chain memory 9. When shortening the required support length, the back-rigid chain 7 is conveyed into the chain memory 9 and wound up there. When extending the required support range, however, the chain is unwound from the chain memory 9.

If you want to make the sheet-like product in a longer length, it makes sense to post the back-end chains 7 as a support system with a slight curvature provided above, so that under load when the web-shaped product rest the back-rigid chains is deformed into a substantially flat, so-called zero position.

In Figure 8, yet another embodiment is shown, in which as

Support system a scissor linkage system 14 is present. With the on the

Scissor linkage system 14 recorded freely co-rotating support rollers or support rollers 21 is also guaranteed for the web-shaped product 20 a sag-preventing pad. A disadvantage of the scissor linkage system 14 is that it at

Shortening of the required support length by the support system 5 must be folded away. This takes place under the clamp carrier 1, 2 by means of a

Guide rail 31 in the manner of a slotted guide.

In Figure 9 is a basic arrangement, the device for printing a web-shaped

Product shown in three-dimensional manner, as shown already in Figure 1. The individual components described in FIG. 1 are therefore not explained separately here again. The same reference numerals mean the same elements in any case. In the further

Embodiment according to Figure 9 are shown as support system 5 five lifting tables 26 in several segments. The lift tables 26 functioning as a support system 5 are arranged at the bottom of the device and have a lifting table linkage, which is not shown in FIG. 9, which can be moved by a hydraulic cylinder 27 in such a controlled manner that the lifting tables 26 move out of their non-support position on the ground can be moved up into the support position, up to the level for the web-shaped product. The lifting table is thus a telescopically movable support surface, which can be moved to the underside of the sheet-like product 20 for its support from the ground position or non-support position into the support position.

In FIG. 10a, in the direction of the longitudinal direction of the device according to the invention, the support system in the form of the lifting table 26 is shown in a non-supporting position arranged on the floor. In this case, the lifting table linkage 28 is folded, so that the immediate support bearing surface of the lifting table 26 rests on the foundation of the lifting table on the ground. The lifting table linkage 28 is by means of, for example, a

Hydraulic cylinder 27 or pneumatic cylinder or servomotor spreadable, whereby the lifting table 26 itself is movable from the non-assist position to the support position. Shown in Figure 10a is the first terminal support 1, which has a divided into individual segments upper terminal block 10 and also divided into individual segments lower terminal block 1 1. In addition, the support frame device 3 is shown schematically.

FIG. 10b shows the same side view of the device according to the invention as in FIG. 10a. However, over the drive of the hydraulic cylinder 27, the lifting table linkage 28 has been spread so far that the lifting table has moved from the ground position to an intermediate position. All other elements and details correspond to those of FIG. 10a.

In FIG. 10c, the lifting table linkage 28 is spread apart by means of the hydraulic cylinder 27 so far that the lifting table 26 is arranged in the support position in the region of the clamping strips 10, 11. The web-shaped product 20 to be supported, which is not shown in FIG. 10 c, then lies on the lifting table 26, so that slack is substantially avoided.
