The plaiting rollers (2, 3) are part of a plaiting carriage (5) which can be displaced along the plaiting length (L) of the web of material (1) with reversible orientation thereof. The aim of the invention is to guide the material to the plaiting point in such a way that the position and quality thereof is not impaired. The plaiting carriage (5) is thus provided with two conveyor belts (6,7) which revolve at least around the plaiting rollers (2, 3), setting said rollers into motion; the web of material (1) is conveyed at least in a partially guided manner between the conveyor belts (6, 7); and the speed of the web of material (1) is equal to that of the conveyor belts (6,7).

Description

  • The present invention relates to a device for depositing a flexible material web with at least one counter-rotating pair of laying rollers, between which the material web is fed to a depositing, wherein the laying rollers are part of a laying carriage, which is movable over the laying length of the material web with reversible orientation, wherein the Laying carriage two comprises at least around the laying rollers circulating conveyor belts, wherein the material web between the conveyor belts is at least partially transported and wherein the speed of the material web is equal to the speed of the conveyor belts.
  • Furthermore, the present invention relates to a method for depositing a flexible material web, wherein the material web is fed via at least one counter-rotating pair of laying rollers at least one depositing location, wherein the material web is moved together with the laying rollers on their Ablegelänge and wherein a change of orientation during the process a freely selectable storage length is carried out, wherein the material web is transported between two conveyor belts to the deposit, which at least circulate around the laying rollers and wherein the material web is moved at the same speed as the conveyor belts.
  • The teaching of the present patent application is based on a prior art, which results from FR 2 739 873. With the device disclosed there, textile web is first compressed between the conveyor belts to form nonwoven with a one-dimensional fiber direction. The conveyor belts thus not only have a transport function but also play a manufacturing role. Below the laying rollers, a collecting belt is arranged, which not only has a transport function, but also the function of allowing additional orientations of the fibers of the web coming from the laying rollers. The collecting belt is constantly spaced from the laying rollers to the exit point of the web and moves in the same plane of movement at right angles to the direction of movement of the laying carriage, across the width of the web. In doing so, zig-zag layers protrude at an angle of approx. 45 °, which leads to the tangled fiber layer of the fleece. Only the storage height changes by the thickness of the material, but not the distance between Collection tape and laying rollers. This nonwoven with a confused fiber layer is solidified inline, ie in the same production process, into the desired product, namely the nonwoven fabric
  • In contrast, the present patent application is concerned with the formation of a stack starting from a finished product. In other words: In the generic state of the art, a pile, a completely unconsolidated material emerging from a textile comb, is added to the conveyor belt and then, between the conveyor belts, a solidification of the nonwoven takes place. While it is generally possible to superimpose nonwoven with the known device, the formation of a stack suitable for packaging purposes is not feasible. In addition, the known device is not suitable for a compact slabs of a material web already for their manufacturing application aspect.
  • From DE 91 16 502 U1 results in a tablature, comprising a laying carriage with laying rollers, between which the web is transported to the deposit. The laying sled can be moved in a reversible orientation. The material web is moved along with the laying rollers or the carriage over a certain laying length, which corresponds to the length of a pallet. In the screening machine in question, the laying rollers are driven by means of a toothed belt and the material web contacts the rollers and is transported between them. Only one roller is driven at a time. In the type of material supply to the deposit point in question, it is disadvantageous that the speed of the material web and the speed of one driven and the other, non-driven roller can be different and thus friction is generated. These differences in speed lead to mechanical stress, imbalance and electrostatic effects of the web as a result of increased friction, which can lead to a deterioration in the quality of the web, to the orientation of the stack and to drape on the discard pile.
  • Another relevant prior art is formed by DE 198 03 837 A1, which deals with the folding and depositing of a flexible web in a zigzag process. First, a web is usually placed vertically between the rollers. In contact with the rollers, the respective web section runs with the same direction of rotation and rotational speed as the rollers. There now follows the step of gripping the web by means of grippers, which are each arranged on the periphery of a roller. The gripping takes place perpendicular to the direction of movement of the web. The web moves with the web material in the gripper mouth. The gripper mouth closes during the further rotation. The jetty slides out. Before it can be stored, the step of letting go of the material web is to be realized first. The release always takes place at the reversal point of the zigzag position. The reciprocating motion during the deposition perpendicular to the direction of movement of the incoming web takes place in fractions of seconds. The storage takes place in elevators, which are moved downwards with a growing stack. There are pile changes made. The known device can be arranged in cascade, so that several bandwidths are served. The known device is disadvantageous in that the storage length of the band is determined by the dimension of the rollers. The smaller the roll dimensions, the more kinks a web has. Straight kinks can lead to a deterioration of the fiber properties, especially since the deposited web still remains for some time in the packed form and may be burdened with other piles of webs. From a design and drive engineering point of view, however, maximizing the roll dimensions is also limited. In addition, the gripper mouth mimic creates impressions on the material that impair the appearance of the material surface. In addition, the gripper mimic with regard to soft materials is unsuitable because the compliance of the material makes it very difficult to grasp or strong impressions remain visible in the material at high gripper pressure. When storing different materials, therefore, a complex machine adaptation is required. Furthermore, when depositing relative speed or friction of the web to be deposited on the previous situation, which in turn may be accompanied by a deterioration of the position of the previous situation, the drape or static charge or with a loss of quality of rubbing materials.
  • Based on the generic state of the art according to FR 2 739 873 the object of the invention is to design and develop a device and a method of the type in question in such a way that a high-quality, compact paneling of the material web at high speed to a material web stack is possible - <becomes light.
  • The above object is achieved with regard to the device by the features of claim 1. Thereafter, a device of the type in question is configured and further developed such that the depositing point is adjustable in height and exerts a contact pressure on a layer of the material web or on a material web stack formed from a plurality of deposited layers of the material web, wherein the back pressure over the parallel to the depositing or . Can be realized to the top deposited layer extending portion of the conveyor belt or wherein the back pressure on the parallel to the deposit or the topmost deposited layer extending Untertrumm the hold-down tape is feasible.
  • Starting from FR 2 739 873 it has been recognized that a device used especially for the nonwoven fabric production can also be applied to the deposition of already existing flexible material webs of all kinds, namely foils, pulp, composites, textile webs or the like. According to the invention it has been recognized that the known purpose of the known device, namely to realize a sub-step of the production of nonwoven fabric, can also be utilized for the formation of a material web stack in connection with the packaging of the slab material web. Next it has been recognized that the Abtafeln can take place in a particularly high quality and at a particularly high speed when the deposit is height adjustable and the top deposited layer of the material web stack is not exposed, but an overlying band - here either a portion of the conveyor belt or Untertrumm a separate holddown band - contacted. In this way, a compact slab even low-weight material webs at high speed is possible. On the one hand, wind influences, air turbulence play no role, on the other hand, light, voluminous material webs can be easily pressed. By depositing within a contact area ensures that no wrinkling occurs, that the edge formation takes place evenly. Instead of exclusively allocating the hold-down function to the conveyor belt, a separate hold-down belt is alternatively claimed. A separation of the material web transport function and the hold-down function is in terms of the realization of simple designs of practical advantage.
  • Compared to DE 91 16 502 U1, the material web reaches its location and nature largely unimpaired to the deposit, since - as is known from FR 2,739,873 - between two conveyor belts is performed, which have the same speed as the material web itself Speed difference between the conveyor belts and the material web is present, electrostatic effects are largely avoided and spared the material itself by reducing friction and the position of the material web - unless otherwise desired - maintained. It is essential that the conveyor belts on the web - whether guided or already stored - only unroll without creating friction. The tensile stress is negligible. In contrast, rollers stress the material web by tension, friction and slippage. The reduction in friction is especially important with regard to the deposition of the material web on the previous layer. The two laying rollers or the laying carriage roll or roll always on the material web, so that it can not lead to a deterioration of the position of the previous situation, to a drape, to a static charge or to a loss of quality. The use of a laying carriage also causes the speed of the uppermost layer of the deposited material web and the speed of the material web reaching the uppermost layer as well as the speeds of the layers to be equal to one another.
  • With regard to the prior art known from DE 198 03 837 A1, it is stated that previous stacks formed from a flexible material web never exceed the dimensions of a Euro pallet and consequently have a high number of kinks, which results in a deterioration of the material structure in FIG can go hand in hand with these areas. For example, the moisture absorption behavior or else the elasticity behavior can be impaired. With freely selectable laying length, the number of kinks can be reduced enormously. It can be realized storage lengths that correspond to the width of a truck bed while saving packaging material for small pack sizes. Modes suitable for transport are made available, whereby the frequency of the transport means loading and unloading operations is reduced.
  • The method of the laying carriage implies that the area of the section of the conveyor belt or of the lower run of the hold-down belt that is effective with respect to the material web, namely the material web contact area, must be variable. It could also be spoken in this context of a change in length of the conveyor belt or hold-down belt with respect to the material web contact area, the length of the conveyor belt or hold-down belt is de facto preserved, but is changed either by winding or by range rearrangement with a view to the material web contact. When moving carriage once larger, even smaller lengths of the conveyor belt or the hold-down belt depending on the position of the laying carriage contact the web and practice the hold-down function. Due to the contact of the conveyor belt or the hold-down belt with the topmost deposited material web wind influences, air turbulence or similar influences can be largely excluded, especially in light materials with a weight below 60 g / m 2 . The contacting in question also allows the deposition of the web at higher speeds, especially at speeds above 200 m / min. A uniform transport of the material web to the depositing point is achieved when each laying roller is associated with a conveyor belt, each being variable in length and one of the topmost layer of the deposited web almost completely contacted when the laying rollers are in the region of the kink. Otherwise, both conveyor belts can contact the respective uppermost layer of the deposited material web located locally before and after the laying rollers.
  • If, instead of the conveyor belt, a separate hold-down strap is provided for exercising the hold-down function, this could run around separate hold-down rollers of the laying carriage. Advantageously, two hold-down bands on both sides of the laying rollers are advantageous, which enable an almost complete hold-down of the respective uppermost layer of the deposited material web.
  • With regard to the variability of the conveyor belt or the hold-down belt, a holding and tensioning device could be provided. In the case of simple constructions, the holding and tensioning device could be designed as a winding device.
  • So that now the functionality of the laying carriage can be produced, a drive motor could be provided. Alternatively, a magnetic drive could find application.
  • Depending on the desired speed and the desired smoothness and integrity of the depositing, a large number of material web feed rollers could be provided which are assigned to the laying carriage, in particular upstream. The arrangement of the web feed rollers could be adapted to the structural conditions of the location of the device according to the invention, so that there is a great deal of freedom in terms of the conveyor belt course. Depending on the desired band path, the material web could, for example, reach the laying rollers vertically or horizontally.
  • As an alternative to the embodiment which is important in practice, with one conveyor belt per laying roller and further material feed rollers, it would also be possible to provide further additional conveyor belts which ultimately convey the material web to the laying rollers.
  • In more complicated designs with multiple web feed rollers could be provided at least one Wegausgleichswagen, which cooperates with the laying carriage. In terms of design, the Wegausgleichswagen could include a toothed belt, which cooperates with the aforementioned holding and tensioning device. The more distance compensation cars are available, the greater the translations can be realized and the more precise and fine the device operates. The high design effort of several Wegausgleichswagen has significance for extremely sensitive material webs, which are almost unverfestigt.
  • Of particular advantage with regard to the supply of pallets, cartons or the like. And their removal after filing the web, the depositing point could be arranged on a support surface in the form of a conveyor belt. A point which is essential for the invention is the height adjustability of the conveyor belt with the depositing point. A supporting surface in the form of a platform of a simple scissor lifting table would also be conceivable, whereby a largely manual loading with the depositing point and a largely manual evacuation, possibly by means of a forklift, is realized , Due to the permanent contact of the deposited web with the overlying to the upper layer portion of the conveyor belt, possibly with the Untertrumm a separate hold-down belt, and the corresponding stroke control of the conveyor belt, it is possible, especially Lightweight, voluminous materials can be compacted by pressing lightly. As a result, the edges are uniformly formed in all layers of the deposited material web and the kinks are loaded only minimally at the reversal points, since neither targeted pressing nor strong kinking takes place. In addition, the height adjustability of the conveyor belt is also advantageous in terms of balancing the growing material web stack. The conveyor belt could be part of an automatic conveyor, which includes additional supply and discharge side transport facilities, which could also be adjustable in height and transport empty floor panels or boxes and remove the finished material web stack. The transport facilities could be designed as closed conveyor belts or as a three- or four-belt conveyor.
  • The laying carriage could be part of a laying module, which could consist of already mentioned components, such as material web feed rollers, path compensation car and the corresponding drive devices associated therewith. The laying module itself could in turn be part of an overall arrangement, which could additionally comprise a material web source, a material web unwinder, a cutting device for longitudinal cutting (pinching or shear cut) of the material into individual material webs and the material feed mimic and possibly a conveyor. To the material web source is to be executed that this could either be formed by a memory or is represented by a roller from which the material web is unwound directly. In practice, a third variant is often used, with the material coming directly from a production plant or laminating plant. In addition to the conveyor belt already explained, the conveyor could also provide additional conveyor belts for removal and removal, for transporting empty deposit boxes, such as floor slabs, and transporting off the finished stack of material piles. This could be realized by means of belt conveyors, some of which are equipped with accessible cover plates. Furthermore, a controller could be provided which position the finished material web stack at a definable distance from one another, in particular on an additional transport roller conveyor, which can also be lifted with a lifting device and lifts the material web stack from the belt conveyors and transported to a packaging line.
  • The overall arrangement comprises - as described above - a plurality of components or assemblies, which are arranged substantially in a main frame. The main frame could be constructed of solid square tubes and have frame longitudinal connectors that allow extension of the main frame. In this way, a complete arrangement comprising only one laying module could be extended or retrofitted. For example. Retrofitting with two further laying modules, traversing devices for moving the material web across the width of the laying module, including orientation changes, depositing points and conveying devices, could take place. In total arrangements with more than three laying modules, one to three more main racks could be added, creating up to 24 bins and more.
  • The laying module or else - in the case of larger devices - several laying modules could or could be arranged parallel or perpendicular to the running direction of the material web unwinder. The modular concept allows a good adaptation to existing space conditions and a space-saving arrangement possibility.
  • For the manner of transporting the material web is stated that the web could be transported across the width of the laying rollers and it comes to the formation of a zigzag stack. Alternatively, at least two material webs could be fed simultaneously in parallel to at least one depository. Within this alternative, three variants could be distinguished. Two strips could be guided within a laying carriage parallel to a depositing point and form a material web stack in parallel tray. In addition, two strips could be transported to a deposit point in a carriage, but form two separate material web stack. Finally, by means of two juxtaposed laying carriages, one material web could each be fed to a depositing station and one web of material webs each formed. Further diverse variants of material web feed and depositing with regard to the number and the depositing pattern are conceivable. A minimum variant with regard to the number of material webs and depositing patterns is given if the width of the material web corresponds to the width of the laying rollers or of the laying carriage. In this case, there would only be a variation width with regard to the storage length per stored layer.
  • Since the laying rollers according to the invention are part of a laying carriage, that is to say a construction which is compact in comparison to known pivotable laying arms, their width dimensions can be relatively high values, up to approximately 4000 mm. With regard to the invention freely selectable storage length of the material web stack dimensions of about 1200 mm - 2700 mm have been found to be advantageous. A storage length of 2400 mm corresponds approximately to the width of a truck bed, so that dimensions suitable for transport can be achieved and thus a reduction in the frequency of loading and unloading operations is achieved, thus reducing labor costs and time. The height dimensions of a material web stack could be approx. 800 - 1500 mm.
  • Drive technically, the laying carriage and possibly the one or more Wegausgleichswagen could be driven by toothed belts and stored on plain bearings. Alternatively, the drive could take place via a second revolving toothed belt drive or directly via a linear drive. As a further alternative to this, the principle of a magnetic drive, in particular as a long-stator linear drive, conceivable, which could be driven at high speed, lowest friction and vibration-free. Here, the laying carriage and the Wegausgleichswagen would float without contact on a magnetic field.
  • Conveniently, the entire arrangement or a single laying module could be controlled. With regard to the overall arrangement, the controller could be designed so that all motion sequences are driven by individual high-precision AC servomotors. A specially developed software could consist of an integration of several software packages. The software packages could comprise a core software of individual laying modules, which is stored in a processor card or special PLC. Furthermore, the software packages could contain a central PLC control for all peripheral processes and the integration of the various components or assemblies, a communication system, in particular in the form of a bus system, and special visualization software.
  • According to one embodiment, the conveyor belts could perform another function, namely to set the laying rollers of the laying carriage in motion.
  • Furthermore, the above object is achieved with regard to the method by the features of claim 23. Thereafter, a method of the type in question, in particular using the device according to the invention described in claim 1, carried out such that the deposit is adjusted in height and in such a way that the topmost deposited layer of the web during placement with its top the Contacting conveyor belt or a hold-down and has contact with the bottom of the depositing point or stack of material web.
  • As with the device according to claim 1, it has also been recognized according to the method according to the invention that the height adjustability of the depositing point in connection with the permanent contact of the deposited material web with the section of the conveyor belt or the lower run of a separate hold-down strip located above it, leads to the upper layer parallel thereto; that lightweight, voluminous materials in particular can be compacted by pressing lightly and at high speed. As a result, the edges are uniformly formed in all layers of the deposited material web and the kinks at the reversal points only minimally burdened, since neither a targeted pressing still takes place a strong buckling. In addition, the height adjustability is also advantageous in terms of balancing the growing material web stack. Due to the material web contact area of the conveyor belt or the hold-down belt to the topmost layer and the contact pressure which can be generated by the height adjustment, it is also precluded that the material web slips and that the material web is contaminated or exposed to other external influences. This also applies to the transport between two conveyor belts.
  • With regard to further advantageous embodiments of the method according to the invention, reference is made to the general description of the device according to the invention together with the local embodiments, especially since there features are explained, which are also relevant to the method.
  • In summary, it is stated that with the device according to the invention and the method according to the invention, according to which the material web is guided between the conveyor belts and no relative speed occurs, a gentle largely wrinkle-free depositing of the material web is made possible. In addition, the laying length of the material web is freely adjustable and the arrangement of other material web feed rollers before the actual laying rollers high deposition speeds can be realized with even, gentle depositing. The device according to the invention could operate as a single machine, a double machine or in a modular network, with all the module modules being synchronized by means of control and regulation units. With the invention and its embodiments, a qualitative and temporal optimization over the prior art is achieved. By adjusting the height of the depositing point and the contact pressure against or parallel to the top layer of the stored web portion of the conveyor belt or Untertrumm the separate hold-down tape a web stack is obtained at high speed, with no surface damage to the web, no wrinkles, no unclean storage of the same occurs , In addition, the material web stack has less loaded kinks. Finally, advantages in terms of transportation and storage can be achieved when stacking large formats.
  • There are now various possibilities for designing and developing the teaching of the present invention in an advantageous manner. For this purpose, on the one hand to the claims subordinate to claims 1 and 23, on the other hand, to refer to the following explanation of several embodiments together with embodiments of the invention with reference to the drawings.
