Description

[0001]Deceleration and / or Alignment Station: The invention relates to a deceleration and / or alignment station for decelerating and / or aligning a fabric hose section transported in the transport direction, preferably transversely to its longitudinal axis, comprising: a transport unit for transporting the fabric hose section in the transport direction, wherein the transport unit has a transport conveyor and a further transport conveyor spaced apart from each other in the transverse direction perpendicular to the transport direction, wherein the fabric hose section can be aligned during transport. From EP 3 814 256 B1, a bottom-laying device is known with which a bottom is formed at one of the ends of a sack transported transversely to its longitudinal axis. With an alignment device, alignment in the transport direction, transversely to the transport direction and about a vertical axis perpendicular to the plane of the hose section is carried out. For this purpose, the hose section is placed on the upper side ofThe hose section is transported in the direction of transport on conveyor belts of a transport device. Conveyor elements in the form of belts are provided to align the hose section, and the hose section rests on these belts. The belts run on common rollers, at least one of which can be driven by its own drive. These belts run at a differential speed and at a higher absolute speed than the conveyor belts, so that the hose section, which is in contact with the belts, is pushed against alignment stops in the form of cams. For this to work, the static friction between the belts and the hose section must be greater than the sliding friction between the conveyor belts and the hose section. The belts are arranged at an angle to the direction of transport, so that the hose section is additionally pushed against a boundary that forms a further alignment stop. In a further embodiment, a frame is also provided, to which the belts are attached.The frame is arranged for alignment and is laterally displaceable to perform a lateral alignment of the hose section. For rotational alignment, the frame can be rotated about a vertical axis. Furthermore, the belts can be operated at different speeds. This allows rotation to be achieved not only by twisting the frame but also by twisting the hose section on the belt. EP 3 814 256 B1 also recognized that alignment via the alignment stops can lead to damage to the hose sections. For example, it can happen that the alignment process is already complete, but the hose section has not yet reached the end of the alignment path. Since the inclined conveying elements continue to act on the hose section even after this point, the hose section continues to be pressed against the stops. This can result in damage to the hose sections. To prevent this damageTo reduce this, EP 3 814 256 B1 provides sensors that detect the current position of the hose section via its edges and transmit this information to a processing and control unit. Depending on the deviation, control commands are generated, which serve to control the drives of the various belts accordingly. The sole purpose of this control system is to reduce damage to hose sections during alignment by limiting contact with the alignment stops. The control system can influence the duration of the alignment process so that the stress on the material is as low as possible at the end of the alignment process. This state of the art therefore retains alignment via alignment stops but attempts to mitigate the negative effects, particularly regarding damage to the hose sections, through a control system. Nevertheless, the problem remains that alignment stops must be used, which manyThis has disadvantages. The edges of the fabric hose section are flexible, resulting in low alignment precision because the edges can deform upon contact with the respective alignment stops. This problem is particularly critical when aligning pinch-bottom fabric hose sections where at least one of the opposing fabric hose walls has a recess, for example, defined by a stepped line, which characterizes the pinch bottom when the end region of the fabric hose section is subsequently folded over. Therefore, the object of the present invention is to reduce or eliminate the disadvantages of the prior art. The invention preferably aims to provide a delay and / or alignment station, a method for delaying and / or aligning, and a device for manufacturing fabric hose sections, preferably pinch-bottom fabric hose sections, with which theDelaying and / or aligning the fabric tube section can be carried out in a targeted and precise manner, particularly without alignment stops. This problem is solved by a delay and / or alignment station according to claim 1, a method according to claim 13, and a device according to claim 15. Preferred embodiments are specified in the dependent claims. According to the invention, the transport unit for transporting the fabric tube section is designed in a clamped state, so that the fabric tube section can be decelerated and / or aligned in the clamped state during transport in the transport direction. Thus, the deceleration and / or alignment of the fabric tube section can be carried out via the transport unit in the clamped state of the fabric tube section. By clamping the fabric tube section during transport in the transport direction, the fabric tube section is decelerated and / or aligned along a delay and / orThe alignment section of the transport unit is constantly held in a fixed position, which is changed by corresponding control of the transport conveyor and the subsequent transport conveyor so that the deceleration and / or alignment of the fabric hose section is achieved. A clamping point of the fabric hose section is held by the transport conveyor, and another clamping point of the fabric hose section is held by the subsequent transport conveyor, such that the clamping point and the other clamping point are always in a predetermined position along the deceleration and / or alignment section. Unlike the prior art described in EP 3 814 256 B1, uncontrolled slippage of the hose section relative to the transport unit is essentially completely avoided. A transport system with conveyor belts, between which the hose sections are clamped, is only mentioned in EP 3 814 256 B1 in a different context with a transport system along whichThe components necessary for forming the layers are arranged. The invention offers the particular advantage that alignment stops can be dispensed with. Preferably, the transport unit is therefore free of alignment stops for the longitudinal and transverse edges of the fabric tube section. The clamping at the clamping point and the further clamping point preferably takes place in the clamping direction perpendicular to the transport plane. In the case of transverse transport, the transport plane is defined by the transport direction and the longitudinal axis of the fabric tube section, from open end to open end. Advantageously, the precision of deceleration, i.e., the reduction of the transport speed of the center of the fabric tube section, and / or alignment, i.e., adjusting the orientation of the fabric tube section, can be significantly increased. Thus, the transfer of the fabric tube section to a station following in the transport direction, preferably a layer formation station, can be made more efficient.The formation of a base at one of the open ends of the fabric tube section can be significantly improved. Furthermore, damage to the fabric tube section during transport along the deceleration and / or alignment section can be reliably avoided. For the purposes of this disclosure, location and direction specifications such as "top," "bottom," "horizontal," and "vertical" refer to an intended operating state of the deceleration and / or alignment station or a device equipped therewith. The transport conveyor and the further transport conveyor are preferably elongated in the transport direction. Preferably, the transport conveyor and the further transport conveyor are spaced apart from each other in the transverse direction, i.e., arranged in different transverse positions, but essentially in the same longitudinal position in the transport direction. In a preferred embodiment, the transport unit for aligning the fabric tube section is in the transverse direction, i.e., inThe transport unit is designed to align the fabric tube section in a transverse, preferably perpendicular, direction to the transport direction. This allows any transverse displacement of the fabric tube section from its intended transverse position to be at least partially, and preferably substantially completely, compensated. In a preferred embodiment, the transport unit is designed to align the fabric tube section in the transport direction, so that any deviation of the fabric tube section from its intended longitudinal position can be at least partially, and preferably substantially completely, compensated. The transport direction runs in a preferably substantially horizontal transport plane, along which the fabric tube section can be transported in a flat, lying position. In a preferred embodiment, the transport unit for aligning the fabric tube section about an axis of rotation is substantially perpendicular to the transport plane, i.e., substantially perpendicular to the main plane of the fabric tube section.In order to be able to slow down and / or align the fabric hose section in the clamped state, the transport conveyor in a preferred embodiment has a transport drive and the further transport conveyor has a further transport drive. In a preferred embodiment, the transport drive and the further transport drive are designed to at least partially, preferably substantially completely, compensate for any misalignment of the fabric hose section by operating the transport drive and the further transport drive differently during transport of the fabric hose section in the transport direction. By controlling the transport drive and the further transport drive differently, different conveying speeds can be transmitted to the two sides of the fabric hose section with respect to its central axis in the transport direction by the transport conveyor and the further transport conveyor.One side of the fabric hose section can be advanced slightly faster than the other side to compensate, at least partially, and preferably essentially completely, for the misalignment of the fabric hose section, i.e., the deviation of its rotational position relative to the normal to the transport or hose plane. Advantageously, the compensation of the misalignment of the fabric hose section can be carried out in constant clamping contact with the transport conveyor and the subsequent transport conveyor. Thus, the fabric hose section is always guided towards a defined target position during the compensation process. Unlike the prior art, not only is the end position fixed, but the fabric hose section is constantly in a defined position that can be adjusted to the target position. During operation, the transport and subsequent transport drives can be controlled in such a way that aThe relative speed between the conveying speed applied by the transport conveyor on one side and the conveying speed applied by the further transport conveyor on the other side of the fabric hose section can be adjusted. In a preferred embodiment, the transport drive and the further transport drive are configured to decelerate the fabric hose section during transport in the clamped position in the transport direction. The center of the fabric hose section can be transported in the transport direction with decreasing transport speed using the transport drive and the further transport drive. For this purpose, the control unit can control the transport drive and the further transport drive such that the fabric hose section is increasingly, preferably substantially continuously, decelerated. In a preferred embodiment, the transport drive and the further transport drive are configured toThe system is designed to compensate for the misalignment of the fabric tube section during deceleration, at least partially, preferably substantially completely, while the fabric tube section is clamped in place. Thus, the compensation of the misalignment and the deceleration of the fabric tube section along the deceleration and alignment path can be superimposed. For this purpose, the transport and subsequent transport drives can be controlled such that the center of the fabric tube section is guided in the transport direction with decreasing transport speed, while the misalignment is at least partially, preferably substantially completely, compensated for by a relative speed between the conveying speeds of the two halves of the fabric tube section on both sides of the central axis. It is essential that the alignment and deceleration of the fabric tube section during transport in the transport direction occur continuously.Clamping engagement with the transport conveyor and the subsequent transport conveyor is achieved so that the longitudinal position of the fabric hose section, i.e., its position in the transport direction, and the rotational position of the fabric hose section with respect to the axis of rotation perpendicular to the transport plane are always fixed. Advantageously, the fabric hose section can always be guided to the target position by the continuous clamping engagement of the transport conveyor and the subsequent transport conveyor, which can be specified to the transport and the subsequent transport drive by a control and / or regulating unit. In a preferred embodiment, the transport conveyor has a point conveyor, preferably a clamping element, and / or the subsequent transport conveyor has another point conveyor, preferably another clamping element. The point conveyor and the subsequent point conveyor create clamping points of the fabric hose section in the clamped state, spaced apart from each other in the transverse direction.The transport direction is guided. This design is particularly advantageous for alignment with respect to the axis of rotation normal to the transport plane. With the point conveyor or the additional point conveyor, contact with the fabric hose section is limited to the clamping points, which, under normal use, preferably extend over less than half, preferably less than a quarter, and particularly less than an eighth, of the fabric hose section's length in the transport and transverse directions. Advantageously, material compression and damage to the fabric hose section during alignment can thus be at least reduced, preferably essentially completely avoided. This distinguishes the point conveyor from a line conveyor, such as a roller, which is in contact with the fabric hose section essentially over its entire length. The (additional) point conveyor also has the advantage that its return to the receiving point, i.e.,Contacting and receiving the next fabric tube section can be facilitated. In a preferred embodiment, the point conveyor and / or the further point conveyor are each rotatably mounted about an axis, preferably about an axis substantially perpendicular to the transport plane. Advantageously, the point conveyor or the further point conveyor can thus accommodate an angular change of the bag section. In a further preferred embodiment, the distance between the centers of the point conveyor and the further point conveyor is variable. In order to effectively transmit the clamping forces during transport, the transport conveyor in a preferred embodiment has a counter element that interacts with the point conveyor for clamping the fabric tube section. Correspondingly, the further transport conveyor has a further counter element that interacts with the further point conveyor for clamping the fabric tube section.In a preferred embodiment, the clamping piece is attached to a circulating element, preferably a circulating belt element, and / or the further clamping piece is attached to a further circulating element, preferably a further circulating belt element, wherein the circulating element is connected to the transport drive and / or the further circulating element is connected to the further transport drive. The transport drive drives the rotation of the circulating element, and the further transport drive drives the rotation of the further circulating element. As the circulating element rotates, the clamping piece attached to it is pressed against the counter element, so that a clamping point for the fabric tube section is formed between the clamping piece and the counter element. Similarly, as the further circulating element rotates, the further clamping piece attached to it is pressed against the further counter element, so that a further clamping point for the fabric tube section is formed between the further clamping piece and theA counter element is formed. The circulating element and the further circulating element preferably do not come into contact with the counter element or the further counter element. In a preferred embodiment, the clamping piece and / or the further clamping piece is made, for example, of polyurethane or acrylonitrile butadiene rubber. In a preferred embodiment, the counter element or the further counter element is designed to be passively dragged along by the point conveyor or the further point conveyor, i.e., moved along with it. In this embodiment, the first or second counter element is not driven, i.e., passive. This embodiment is particularly simple in design. This embodiment is particularly efficient and robust. In a preferred embodiment, the counter element is a point conveyor element, which is preferably attached to a circulating element, preferably a circulating belt, and / or the further counter element is a furtherA point conveying element, preferably attached to a further circulating element, preferably a further circulating belt. Preferably, the point conveying element is a clamping plunger and / or the further point conveying element is a further clamping plunger, which preferably corresponds to the clamping piece or further clamping piece described above. Alternatively, the counter element is a circulating element, preferably a circulating belt. In a preferred embodiment, the point conveying element and / or the further point conveying element is each rotatably mounted about an axis, preferably about an axis substantially perpendicular to the transport plane. Advantageously, this prevents wrinkling caused by rotation. In a further preferred embodiment, the distance between the centers of the point conveying element and the further point conveying element is variable. In an alternative embodiment, the counter element is a linear transport element.Preferably a belt element, and / or the further counter element is a further linear transport element, preferably a further belt element, which is in contact with the clamping piece or with the further clamping piece along linear contact surfaces. In a preferred embodiment, the transport conveyor has a driving device with a driving element and / or the further transport conveyor has a further driving device with a further driving element, wherein the driving element or the further driving element is configured to set the counter element in motion before the point conveyor makes contact with the counter element or before the further point conveyor makes contact with the further counter element. Thus, the driving element precedes the point conveyor. The further driving element precedes the further point conveyor. With the aid of the (further) driving element, the (further) counter element can preferably be set in motion beforeThe (additional) point conveyor comes into clamping contact with the (additional) counter element. Advantageously, this avoids abrupt starting and thus (shear) stress on the fabric hose section. To reduce the material stress on the counter element, in particular the frictional stress on the counter element caused by friction with the drive element, the transport conveyor, in an alternative embodiment, has at least one counter element drive for driving the counter element and / or the additional counter element. Preferably, the counter element is connected to the counter element drive and / or the additional counter element is connected to a further counter element drive. Preferably, the counter element drive is designed as an electric motor. The counter element drive can be coupled and / or synchronized with the transport drive of the transport conveyor. It is advantageous if the points of the first fabric hose wall and the second fabric hose wall are arranged one above the other.The fabric hose section experiences the same conveying speed. Preferably, the counter element is driven indirectly via a pulley connected to the counter element drive. Preferably, the counter element and the further counter element are driven separately, i.e., by one counter element drive and another counter element drive. Preferably, the counter element and / or the further counter element are driven such that the speed of the counter element corresponds to the conveying speed applied by the conveyor and / or the speed of the further counter element corresponds to the conveying speed applied by the further conveyor. It is advantageous if the counter element and the further counter element can have different speeds. To enable alignment of the fabric hose section in the transverse direction and / or adjustment for different bag formats, an adjustment unit is preferably used.with an adjustment drive for adjusting the transport conveyor and / or the further transport conveyor together and / or individually in the transverse direction. By adjusting the transport conveyor and the further transport conveyor together in the transverse direction, a transverse offset of the fabric tube section can be at least partially, preferably substantially completely, compensated for, as described above. By adjusting the transport conveyor relative to the further transport conveyor in the transverse direction, the transport unit can be adjusted for different bag formats. A ball screw drive, for example, can be provided as the adjustment drive. In a preferred embodiment, a control and / or regulating unit is provided for controlling and / or regulating the transport unit, preferably the transport and / or the further transport drive, and / or the adjustment unit. To guide the fabric tube section to its target position, the control and / orIn a preferred embodiment, the control unit is connected to a sensor unit. The control unit processes the signals from the sensor unit to generate control signals for the transport drive and / or for the subsequent transport drive and / or for the adjustment unit based on deviations between setpoint and actual values. In a preferred embodiment, the sensor unit has a first sensor for detecting misalignment of the fabric tube section. Preferably, the first sensor has several sensor elements spaced apart in a transverse direction, which detect the passage of the leading edge of the fabric tube section at transversely spaced points during transverse transport of the leading longitudinal edge. If a time difference is detected between the passage of these points, the control unit can calculate a misalignment, which is at least partially, preferably completely, corrected along the delay and / or alignment path.in a preferred embodiment, the sensor unit has, in addition to or as an alternative to the first sensor, a second sensor, preferably an ultrasonic fork sensor, for detecting a deviation of the fabric tube section in the transverse direction, preferably by detecting at least one of the opposite transverse edges of the fabric tube section. In a preferred embodiment, the control and / or regulating unit is configured to at least partially, preferably in a substantially complete, compensate for the misalignment of the fabric tube section detected by the first sensor by differently controlling the transport drive and the further transport drive during the transport of the fabric tube section in the clamped state. In a preferred embodiment, the control and / or regulating unit is configured to compensate for the deviation of the fabric tube section detected by the second sensor inThe transverse direction is at least partially, preferably substantially completely, compensated for by jointly adjusting the transport conveyor and the further transport conveyor in the transverse direction by means of the adjustment unit during the transport of the fabric hose section in a clamped state. The transport unit is preferably a transverse transport unit for transporting the fabric hose section in a transverse transport position in which the longitudinal axis is oriented substantially perpendicular to the transport direction. In the inventive method for decelerating and / or aligning a fabric hose section transported in the transport direction, preferably transverse to its longitudinal axis, at least the following steps are carried out: Transporting the fabric hose section in the transport direction, wherein the fabric hose section is transported in a clamped state in the transport direction, wherein the fabric hose section is transported in the transport direction inThe clamped state is delayed and / or aligned. In a preferred embodiment of the method, the fabric tube section is simultaneously delayed and aligned along a deceleration and alignment path while in the clamped state. In a preferred embodiment, after the fabric tube section has been delayed and / or aligned, a bottom is formed at one of the open end regions of the fabric tube section. Preferably, a folded bottom is formed, in which one of the end regions of the fabric tube section is folded over onto an adjacent region of the fabric tube section. In a preferred embodiment, a pinch bottom is provided as the folded bottom. To prevent the escape of filler material through the pinch bottom, the pinch bottom forms a sealing closure, i.e., a gasket. For this purpose, at least one of the two opposingThe fabric tube walls of the folded end section have a, preferably stepped, recess. As is known in the prior art, the recess can be produced in a previous manufacturing step by tearing the fabric tube section along a stepped tear line from a fabric tube web. By folding the end section with the, preferably stepped, recess on at least one of the fabric tube walls, the seal is formed, which prevents the escape of filling material in the finished pinch bag. In a further preferred embodiment, the folded bottom is straight, i.e., the leading edges of the fabric tube walls continued into the end section are straight and identical. Fabric bags produced with such a folded bottom are also referred to as cushion bags. The conveying device according to the invention for conveying a fabric tube section in a transport direction, preferably transverse to its longitudinal axis,The system comprises: a deceleration and / or alignment station, preferably in one of the embodiments described above, for decelerating and / or aligning a fabric hose section transported in the transport direction, preferably transversely to its longitudinal axis; a transfer station arranged upstream of the deceleration and / or alignment station in the transport direction, the transfer station comprising a transfer conveyor. In a preferred embodiment, the transfer conveyor has a transfer drive. The fabric hose section can be transferred to the deceleration and / or alignment station at a transfer speed using the transfer conveyor. In order to transfer the fabric hose section from the transfer station to the deceleration and / or alignment station in a defined transfer position, the transfer conveyor in a preferred embodiment is designed to guide the trailing side of the fabric hose section, i.e., the rear side, which is the side facing forward.During transverse transport, the rear longitudinal edge of the fabric hose section is moved in a clamped position in the transport direction by the deceleration and alignment station when the leading side of the fabric hose section is taken over. Thus, the lagging side of the fabric hose section is still clamped in the transfer station, while the leading side of the fabric hose section is already clamped by the deceleration and / or alignment station. The lagging side of the fabric hose section is only released by the transfer conveyor once the transport unit has taken over the leading side of the fabric hose section in its clamped position. This design has the advantage that the fabric hose section can be transferred with particular precision. Therefore, the fabric hose section can always maintain its defined position. If the fabric hose section were released prematurely, theThe fabric hose section slips while lying on lower transport elements. To initiate the deceleration of the fabric hose section, the transport unit of the deceleration and alignment station is designed to reduce the transport speed after taking over the front side of the fabric hose section. At the reduced transport speed, the fabric hose section can then be transferred to a bottoming station. To maintain the clamping contact in the transfer station until it is taken over by the deceleration and / or alignment station, the transfer conveyor has a rotating transfer element, preferably a transfer roller, which preferably extends substantially transversely to the transport direction. This element is used to move the trailing side of the fabric hose section while it is clamped in place during the takeover of the leading side of the fabric hose section by the deceleration and alignment unit. Preferably, the transfer roller presses theA fabric tubular bag is moved against a counter-conveyor to establish the clamping contact. For example, the transfer roller can be arranged above the transport plane and the counter-conveyor below the transport plane. To be able to transfer fabric tubular sections of varying lengths in the transport direction, i.e., during transverse transport of different widths, in a constant clamping position, the transfer element is adjustable in the transport direction to accommodate different widths of the fabric tubular section. Thus, the longitudinal position, i.e., the position as seen in the transport direction, of the transfer element can be adjusted. In a preferred embodiment, the transfer conveyor has a transfer belt conveyor with a transfer belt running around the transfer roller. The transfer belt is set in motion by the transfer drive. To convey the fabric tubular section into the transfer position, the transfer belt is in frictional contact with the fabric tubular section. In aIn a structurally simple and precisely adjustable design, the transfer conveyor features a deflection pulley around which the transfer belt runs. The deflection pulley can be positioned at different heights to adjust the transfer roller in the transport direction. This allows for adaptation to various types of fabric hose sections. In a preferred embodiment, the transfer conveyor includes an additional transfer belt conveyor with an additional transfer belt. Preferably, the transfer belt conveyor is an upper transfer belt conveyor located above the transport level, and the additional transfer belt conveyor is a lower belt conveyor located below the transport level. In this embodiment, it is advantageous if the fabric hose section is transported between a lower run of the upper transfer belt conveyor and an upper run of the lower transfer belt conveyor. In the area of ​​the transfer roller, theThe trailing side of the fabric hose section is clamped before the deceleration and alignment station takes over the fabric hose section. Since no additional forces act on the fabric hose section at this point, the conveying between the tubes is sufficient to continue conveying the fabric hose section in a defined position. In a preferred embodiment, the lower transfer belt conveyor is extended beyond the front end of the upper transfer belt conveyor, preferably beyond the front deflection roller, in the transport direction, i.e., forwards. Advantageously, the trailing side of the fabric hose section can thus be conveyed after the leading side of the fabric hose section has been taken over by the deceleration and / or alignment unit, whereby the clamping of the leading side is accomplished by the deceleration and / or alignment unit. To further protect the fabric hose section against displacement and / or slippage relative to theTo secure the transfer belt, an alternative embodiment of the transfer conveyor has at least one pressure and / or support roller. Preferably, the at least one pressure and / or support roller is designed to press a section of the transfer belt of the upper transfer belt conveyor, preferably at least with its lower running section, in the direction of the transport plane, i.e., preferably substantially downwards. It is advantageous if the at least one pressure and / or support roller presses the transfer belt towards a conveyor table and / or towards at least one counter-pressure roller, wherein the counter-pressure roller is preferably arranged below the transfer belt and / or the at least one pressure and / or support roller, wherein the counter-pressure roller and the at least one pressure and / or support roller preferably form a pair of pressure rollers, wherein the counter-pressure roller is preferably arranged below the fabric hose section, and wherein the counter-pressure roller is preferablyThe transfer belt of the additional, i.e., the lower, transfer belt conveyor is tensioned at least section by section. The counter-pressure roller is particularly preferably designed as a further pressure and / or support roller. It is advantageous if the at least one pressure and / or support roller increases the contact force of the transfer conveyor, in particular the upper transfer belt conveyor, which presses the fabric hose section against the additional transfer belt conveyor, at least section by section, preferably over the entire conveying length of the deceleration and / or alignment station. Preferably, the at least one pressure and / or support roller tensions the transfer belt at least section by section, preferably over the entire conveying length of the deceleration and / or alignment station. Preferably, the at least one pressure and / or support roller is a passive roller, i.e., driven only by engagement with the transfer belt. Preferably, the at least one pressure and / or support rollerHeight-adjustable, preferably mounted on a pressure device for regulating the contact pressure. Preferably, the at least one pressure and / or support roller is spring-mounted, i.e., preferably slidably mounted at least in the vertical direction. Preferably, the at least one pressure and / or support roller is arranged along the transport direction in front of the transfer roller, preferably also in front of the deflection roller. Preferably, at least one further pressure and / or support roller is arranged along the transport direction between the transfer roller and the deflection roller. The transfer station in one of the embodiments described above can also be used with a different deceleration and / or alignment station than described above. Thus, the present disclosure also relates to a transfer station in one of the embodiments described above. In a preferred embodiment, a receiving station is provided for receiving the fabric hose section from theA delay and / or alignment station is provided. The transfer station can, for example, include a magnetic chain conveyor. The inventive device for manufacturing woven bags has a delay and / or alignment station in one of the embodiments described above. In a preferred embodiment, the device has an unwinding station with which a flat woven web is unwound as the starting material for the woven bags. Alternatively, the woven tubular web can already be in tubular form. In a preferred embodiment, the device further has a station for forming tear lines at regular intervals in the flat woven web or the woven tubular web. The tear lines are preferably formed by perforations and / or weakening. The station preferably has at least one perforation unit, preferably a laser unit, for weakening or perforating the flat woven web or theThe fabric tubular web is formed along the tear-off lines. Alternatively, the station for forming the perforations can have a roller equipped with perforating blades that interact with a counter-roller. The tear-off lines preferably have a stepped shape, with which a sealing closure, i.e., a gasket, is formed in the final pinch-bottom fabric bag to prevent the escape of filling material. The details of the stepped line are explained, for example, in EP 2 117 821 B1. In a preferred embodiment, the device has a tubular forming station, preferably in the transport direction after the station for forming the tear-off lines, with which the fabric flat web is folded over and processed into a fabric tubular web with a longitudinal seam. The tubular forming station can also be configured to form longitudinal folds on the long sides of the fabric flat web. In a preferred embodiment, the device has inIn the transport direction after the tear-off station, the device includes a rotary station for rotating the fabric tube sections by essentially 90° from a longitudinal transport position to a transverse transport position. Before the rotary station, the longitudinal axes of the fabric tube sections are essentially aligned in the transport direction; after the rotary station, they are essentially perpendicular to the transport direction. In a preferred embodiment, the device includes a deceleration and / or alignment station in the transport direction after the rotary station for delaying the fabric tube sections for further processing. In a preferred embodiment, the device includes a bottom-forming station in the transport direction after the deceleration and / or alignment station for forming folded bottoms, preferably pinch bottoms, on the fabric tube sections, so that folded-bottom fabric bags, preferably pinch-bottom fabric bags, are obtained. In a preferred embodiment, the device includes a bottom-forming station in the transport direction after the deceleration and / or alignment station for forming folded bottoms, preferably pinch bottoms, on the fabric tube sections, so that folded-bottom fabric bags, preferably pinch-bottom fabric bags, are obtained.Following the bottom-forming station, a drop-off station is provided for depositing the folded-bottom fabric bags, preferably pinch-bottom fabric bags. In a preferred embodiment, the stations described above are arranged in a line. Thus, the center of the fabric tube section can be conveyed straight through the stations of the device. Advantageously, no change in the transport direction, in particular no deflection of substantially 90°, of the center of the fabric tube section is required. In a preferred embodiment, the stations of the device described above are designed to keep the fabric tube section in a defined position at all times during transport through these stations. Advantageously, the position of the fabric tube section is therefore precisely determined at all times. The deceleration and / or alignment station described above can also, preferably in a commissioning mode, be used as an acceleration station.The device described above must be designed for this purpose. During commissioning, the fabric web can be unwound for the first time, with the beginning of the web being manually threaded through all stations up to the tear-off station. The device can then be put into operation. The device may require time to accelerate from its initial speed (starting ramp) to operating speed. For example, for bottom formation, preferably by hot air welding, the initial speed may be insufficient because the hose section is guided too slowly along the bottom formation station, preferably along a hot air nozzle. This can cause the bag material to melt. Furthermore, there is a risk of damage to the device. Therefore, the deceleration station can be used during commissioning to accelerate the hose sections, thus increasing the transport speed of the hose sections to the required speed.to increase the speed of the bottom formation station. According to the invention, a method for manufacturing a fabric bag, preferably a fold-bottom fabric bag, more preferably a pinch-bottom fabric bag, can also be carried out, in which the deceleration and / or alignment and / or acceleration is carried out according to one of the embodiments described above. The method for manufacturing the fabric bag can also include at least one of the following steps, preferably all of the following steps, preferably sequentially: i. Unwinding a fabric sheet as starting material; ii. Forming tear lines at regular intervals in the fabric sheet, preferably by perforating and / or weakening, for example by laser cutting, the fabric sheet; iii.

In a preferred embodiment, longitudinal folds are formed on the longitudinal sides of the fabric tube web, preferably during tube formation. The invention is further described below with reference to an embodiment illustrated in the drawings.Explained. Fig. 1 schematically shows a device for manufacturing pinch-bottom fabric bags, in which a delay and / or alignment station according to the invention is provided for delaying and / or aligning a fabric tube section. Figs. 2A, 2B, 3 to 6B show different views of the delay and / or alignment station. As can be seen from Fig. 1, the device 1 has an unwinding station 2 with which a fabric web 3 is unwound. The fabric web 3 has a tape fabric made of stretched plastic tapes, for example polypropylene. A film, preferably made of BOPP, is preferably applied to one side of the tape fabric. As can be seen from Fig. 1, the device 1 further has a station 4 for forming tear lines 5 at regular intervals in the fabric web 3. The tear lines 5 are formed by material weakening or perforations. Station 4 preferentially exhibits at least oneThe perforation unit 6, in the example shown a laser unit, is used to weaken or perforate the fabric sheet 3 along the tear lines 5. Alternatively, the station 4 for forming the perforations can have a roller equipped with perforating blades that interact with a counter roller (not shown). The tear lines 5 preferably have a stepped shape, with which a seal is formed in the final pinch-bottom fabric bag. As can be seen from Fig. 1, the device 1 further has a tube-forming station 7, with which the fabric sheet 3 is folded over along its longitudinal axis, an overlap area is formed, and this overlap area is provided with a longitudinal seam 8 to form a fabric tube sheet 9. Longitudinal folds can also be provided. As can be seen from Fig. 1, the device 1 further has a tear-off station 10, with which the fabric tube sheet 9 is cut into individual sections at theirThe open ends of the fabric hose sections 11 are cut. As can be seen in Fig. 1, the device 1 further comprises an intermediate transport and discharge station 12 for the intermediate transport of the fabric hose sections 11 and the discharge of feed material. As can be seen in Fig. 1, the device 1 further comprises a rotary station 13 for rotating the fabric hose sections 11 by 90° from a longitudinal transport position, in which the longitudinal axes of the fabric hose sections 11 are arranged in the transport direction 14A, to a transverse transport position, in which the longitudinal axes of the fabric hose sections are arranged in the transverse direction 14B perpendicular to the transport direction 14A, and still in the transport plane. Thus, the open ends of the fabric hose sections 11 are located at the front and rear ends before the rotary station, and at the sides of the fabric hose sections after the rotary station. As can be seen from Fig. 1, the device 1 further includes a delay station 15 for delaying.The device 1 has a bottom-forming station 16 for forming folded bottoms, preferably pinch bottoms 17, on the fabric tube sections 11, so that folded-bottom fabric bags 18, preferably pinch-bottom fabric bags, are obtained. As can be seen in Fig. 1, the device 1 also has a depositing station 19 for depositing the fabric bags 18. In the example shown, the bottom-forming station 16 has a conveying device 20 for conveying the fabric tube section 11 in a conveying direction 21 (Fig. 2A, Fig. 2B, Fig. 3). The conveying device 20 can, for example, be a magnetic chain conveyor. The fabric tube section 11 has a first 11A and a second fabric tube wall 11B, which are fed to the soil formation station 16 in a flat, overlapping position by the conveying device 20. A folding device 22 then folds one of the openThe end regions of the fabric hose section 11 are folded over. In doing so, one of the open end regions of the fabric hose section, which is formed from the end sections of the first 11A and the second fabric hose wall 11B, is folded over onto a connecting section of the first fabric hose wall 11A. Furthermore, a hot gas nozzle 23 is provided, with which hot gas, preferably hot air, is expelled between the outer surface of the connecting section of the first fabric hose wall 11A and the inner surface of the end region of the fabric hose section 11 facing the connecting section. In the example shown, a guide device 24 guides the end region of the fabric hose section 11 past the hot gas nozzle 23 in the folded-over state, i.e., folded over by essentially 180°. By means of the guide device 24, the inner surface of the end region is spaced from the outer surface of the adjacent first fabric hose wall 11A such that a gap is formed. InThe hot gas nozzle 23 is inserted into this gap. When the fabric hose section 11 is conveyed in the conveying direction 21, the hot gas is discharged into the gap via the hot gas nozzle 23. The hot gas partially melts the material. A pressing device 25 presses the end region against the first fabric hose wall 11A of the fabric hose section 11, thus forming the thermal weld. Following the pressing device 25 is the fabric bag 18 with the folded bottom, which, if a stepped tear-off line 5 is used, serves as the pinch bottom 17. In the example shown, the deceleration and alignment station 15 is designed to decelerate and align the fabric hose section 11, which is transported in the conveying direction 14A transversely to its longitudinal axis (Fig. 2A, Fig. 2B). For this purpose, the delay and alignment station 15 has a transport unit 26 for transporting the fabric hose section 11 in transport direction 14A.Transport unit 26 comprises a transport conveyor 27 and a further transport conveyor 28, which are preferably identical in design. The transport conveyor 27 and the further transport conveyor 28 are arranged essentially parallel and at a distance in the transverse direction 14B, i.e., essentially in the same longitudinal position in the transport direction 14A, but in different transverse positions in the transverse direction 14B. During the transport of the fabric tube section 11 along the transport unit 26, the fabric tube section 11 can be slowed down and aligned in order to precisely carry out the subsequent bottom formation. For this purpose, the transport unit 26 is designed to transport the fabric tube section 11 in a clamped state, i.e., fixed in the transport direction 14A, in the transverse direction 14B, and perpendicular to the transport plane, here in the vertical direction, so that the fabric tube section 11 is transported in the transport direction 14A in theThe clamped state can be delayed and aligned. The longitudinal and transverse edges of the fabric hose section 11 are always free, i.e., not limited by alignment stops. Unlike the prior art, the transport unit 26 is therefore free of alignment stops against which the fabric hose section 11 had to be conveyed for alignment in the prior art. In the example shown, the transport unit 26 is configured for the transverse transport of the fabric hose section 11 essentially perpendicular to its longitudinal axis, which runs from open end to open end of the fabric hose section. Thus, the transport plane is defined by the transport direction 14A and the longitudinal axis of the fabric hose section 11. In the example shown, the transport conveyor 27 has a transport drive 29 and the further transport conveyor 28 has a further transport drive 30, which can be controlled independently of each other. Preferably, the transport drive 29 and theFurther transport drives 30 are designed as separate drives. In the example shown, the transport conveyor 27 has at least one point conveyor, here at least one clamping piece 31, which is attached to a circulating element, here a circulating belt element 32. In the example shown, two clamping pieces 31 are fixed to the circulating belt element 32 (see Fig. 3). The transport drive 29 sets the circulating belt element 32 in rotation. Accordingly, the further transport conveyor 28 has another point conveyor, here another clamping piece 33, which is attached to another circulating element, here another circulating belt element 34. In the example shown, two further clamping pieces 33 are fixed to the further circulating belt element 34. The transport drive 30 sets the further circulating belt element 34 in rotation. Only the at least one clamping piece 31 and the at least one further clamping piece 33, but not the circulating belt element 34, are driven by the transport drive 30.Belt element 32 and the further circulating belt element 34 come into contact with the fabric hose section 11. The at least one clamping piece 31 and the at least one further clamping piece 33 cooperate with a counter element 35 and a further counter element 36, respectively, to clamp the fabric hose section 11 in the transport direction 14A. The counter element 35 and the counter element 36 The further counter element 36 is passively, i.e., without its own drive, essentially dragged along by the first or the second (further) point conveyor, i.e., moved at the same speed (see Fig. 4). In the example shown, the counter element 35 is a circulating element 37, here a circulating belt 38. Accordingly, the further counter element 36 is another circulating element 39, here another circulating belt 40. Thus, the fabric hose section 11 is clamped at two clamping points spaced apart from each other in the transverse direction 14B, with one clamping point being located between the clamping piece 31.and the counter element 35 and the other clamping point is formed between the further clamping piece 33 and the further counter element 36. In the example shown (see Fig. 5), the transport conveyor 27 has a driving device 41 and the further transport conveyor 28 has a further driving device 42, wherein the driving device 41 and the further driving device 42 are designed to set the counter element 35 in motion before the press contact of the clamping piece 31 with the counter element 35 and before the press contact of the further clamping piece 33 with the further counter element 36, respectively. Preferably, the driving device 41 is attached to the point conveyor and the further driving device 42 is attached to the further point conveyor. For example, the (additional) carrying device can be made of fiber-reinforced plastic, preferably carbon fiber-reinforced plastic. In the example shown, an adjusting unit 43 is used for the joint adjustment of the transport conveyor.27 and the further transport conveyor 28 in transverse direction 14B are provided. The function of the adjusting unit 43 is described in more detail below. Furthermore, the transport conveyor 27 and the additional transport conveyor 28 can also be individually adjusted in the transverse direction 14B by means of the adjusting unit 43 in order to set the transverse distance between the transport conveyor 27 and the additional transport conveyor 28 before commissioning with regard to the format of the fabric hose section 11 to be transported (see Fig. 5). In the example shown, a control unit 44 is provided for controlling and regulating the transport unit 26, in particular the transport drive 29 and the additional transport drive 30, and the adjusting unit 43, in particular an adjusting drive (Fig. 2a, Fig. 2B). In order to follow the actual position of the fabric hose section 11 to a target position of the fabric hose section 11, the control unit 44 is equipped with a sensor unit 45 for detecting the actual position of theThe fabric hose section 11 is connected. Furthermore, the control unit 44 is configured to calculate a target position of the fabric hose section. The control unit 44 processes the signals transmitted by the sensor unit 45 regarding the actual position of the fabric hose section 11 in order to generate control signals for one or more drives of the transport unit 26, i.e., the transport drive 29, the further transport drive 30, or the adjustment unit 43, from any deviation of the actual position from the target position (see Fig. 2A, Fig. 6). In the example shown, the sensor unit 45 has a first sensor 46 for detecting a misalignment of the fabric hose section. For this purpose, the first sensor 46 in the example shown has several sensor elements 47, for example, light barriers, which are spaced apart from each other in the transverse direction 14B. This allows the control unit to determine the misalignment of the fabric hose section 11 (see Fig. 2A, Fig. 6). In the shownFor example, the sensor unit 45 also has a second sensor 48, such as a fork sensor. One of the transverse edges of the fabric hose section is passed between two fork elements of the fork sensor, so that the position of the transverse edge in transverse direction 14B can be detected via a measurement signal. From the signal of the fork sensor, the control unit 44 determines the deviation of the current transverse position from the desired transverse position of the fabric hose section 11. With the aid of the transport unit 26 in conjunction with the control unit 44, deviations of the actual position of the fabric hose section 11 from the target position of the fabric hose section during transport in transport direction 14A can be compensated for. The control unit 44 is designed to compensate for the misalignment of the fabric hose section 11 detected by the first sensor 46 by differently controlling the transport drive 29 and the further transport drive 30 during transport.The control and regulating unit 44 is further designed to compensate at least partially, preferably substantially completely, for the deviation of the fabric hose section 11 in the transverse direction detected by the second sensor 48 by simultaneously adjusting the transport conveyor 27 and the further transport conveyor 28 in the transverse direction 14B by means of the adjustment unit 43 during the transport of the fabric hose section 11 in the clamped state. It is advantageous that the misalignment of the fabric hose section 11 can be compensated at least partially, preferably substantially completely, by operating the transport drive 29 and the further transport drive 30 differently during the transport of the fabric hose section 11 in the transport direction 14A. The control and regulating unit 44 is finally designed totrained to control the transport drive 29 and the further transport drive 30 in such a way that, during transport along the transport unit 26, the fabric hose section 11 is decelerated in the clamped state. Thus, the following method can be carried out to decelerate and / or align a fabric hose section 11 transported in the transport direction 14A, preferably transversely to its longitudinal axis: Transporting the fabric hose section 11 in the transport direction 14A, wherein the fabric hose section 11 is transported in a clamped state in the transport direction 14A, wherein, during transport in the transport direction 14A, the fabric hose section 11 is decelerated in the clamped state a) by slowing down the transport speed of the center of the fabric hose section 11 set with the transport conveyor 27 and the further transport conveyor 28 and / or b) by different conveying speeds of the Transport conveyor27 and the further transport conveyor 28 are aligned with respect to the two halves of the fabric hose section 11 with respect to a misalignment and / or c) are aligned with respect to a deviation from the target transverse position by jointly adjusting the transport conveyor 27 and the further transport conveyor 28 in the transverse direction 14B. In the example shown, a transfer station 49 is also arranged between the rotary station and the deceleration and alignment station 15 (Fig. 2A, Fig. 6). The transfer station 49 has a transfer conveyor 50 and at least one transfer drive 51 (Fig. 2a, Fig. 2B). The transfer conveyor 50 allows the fabric hose section 11 to be transferred to the deceleration and alignment station 15 at a transfer speed. The transfer conveyor 50 allows the lagging side, here the rear longitudinal edge, of the fabric hose section 11 to be guided by the transfer conveyor 50 during the transfer of the leading side, here the front longitudinal edge, of the fabric hose section 11.The fabric hose section 11 is clamped in place at the delay and alignment station 15 (Fig. 4). Thus, the fabric hose section 11 is moved in the transport direction 14A in a clamped state by both the transfer conveyor 50 and the transport unit 26 for a transfer period (Fig. 4). The transport speed is reduced by the transport drive 29 and the further transport drive 30 of the delay and alignment unit 15 only after the front end of the fabric hose section 11 has been taken over. In the example shown, the transfer conveyor 50 has a rotating transfer element, here a transfer roller 52, which holds the rear longitudinal edge of the fabric hose section 11, while the front longitudinal edge of the fabric hose section 11 is clamped by the transport conveyor 27 and the further transport conveyor 28. Thus, the clamping contact in the transfer station 49 can be maintained until the fabric hose section 11 is taken over by the delay and / or alignment station 15.(Fig. 4). In the example shown, the transfer conveyor 50 has a transfer belt conveyor 53 with at least one, for example four, transfer belts 54 rotating around the transfer roller 52 (Fig. 6). The at least one transfer belt 54 is set in motion by the transfer drive 51 (Fig. 2A). To convey the fabric hose section 11 into the transfer position, the transfer belt 54 is in frictional contact with the fabric hose section 11 (e.g. Fig. 6). In the example shown, the transfer conveyor 50 has an additional transfer belt conveyor 55 with at least one, for example four, additional transfer belts 56. Preferably, the transfer belt conveyor 53 is an upper transfer belt conveyor and the additional transfer belt conveyor 55 is a lower belt conveyor. The fabric hose section 11 is transported between a lower run of the upper transfer belt conveyor and an upper run of the lower transfer belt conveyor (see Fig. 2A, Fig. 6). Fig. 6BFigure 1 shows an alternative embodiment of the transfer station 49B, in which the transfer conveyor 50B has several pressure and / or support rollers 58 for pressing the transfer belt 54 of the transfer belt conveyor 53 onto the transport plane. The pressure and / or support rollers 58 press the transfer belt 54 towards the transport plane, i.e., essentially downwards. The pressure and / or support rollers 58 are arranged at regular intervals along the transport direction 14A of the deflection roller 57. In the example shown, the transfer conveyor 50B has a deflection roller 57 around which the transfer belt 54 runs, wherein the deflection roller 57 can be arranged in different height positions, preferably essentially steplessly height-adjustable, for adjusting the transfer roller 52 in the transport direction 14A. To transport fabric hose sections 11 of different lengths in the transport direction 14A, i.e., of different widths during the transverse transport shown, in constantTo enable the transfer to the clamping position, the transfer roller 51 can be adjusted in the transport direction 14A (Fig. 6). In the example shown, the lower transfer belt conveyor extends beyond the front end of the upper transfer belt conveyor, preferably beyond the front deflection roller, in the transport direction, i.e., forwards.
