Description

The present invention relates to a method and apparatus for accurately positioning and processing textile articles, particularly basting pieces.

In the prior art there are methods and corresponding devices in which textile articles, for example textile webs or textile basting pieces, are manually or automatically (pre-)aligned and correspondingly aligned, for example processed. It is known to be fed to a step or to a transport device of an apparatus. Conveying equipment conveys textiles through the apparatus to various processing stations.

With such a method and corresponding apparatus, not only textile basting pieces but also basting pieces made of any material that can be processed in the same manner as textile materials are handled. These include, for example, basting pieces made of paper or plastic.

For example, automatic (pre-)registration of fibrous webs is known, in which the fibrous web is accurately registered prior to processing, for example cutting the web into basting pieces.

Alignment of the fibrous web is performed mechanically, for example by mechanically interrogating the outer edge or pile edge of the textile with reference to segmented alignment rails. The alignment rails then set the correct alignment.

In order to be able to perform such mechanical alignment, the fibrous web must have edges that can be detected by alignment rails so that the web can be pulled to the desired position. . This leads to the disadvantage that this type of alignment cannot be carried out in the absence of an outer edge or pile edge, for example according to the handle or the thread or mesh flow. Furthermore, the textile must be endless, as is the case with fibrous webs. This type of alignment is not possible with textile basting pieces.

After the fibrous web is correctly aligned, the basting pieces can be cut accurately. The basting pieces are subsequently subjected to further processing, such as hemming, folding and/or sewing, and each basting piece is automatically or manually handed over to a piece of equipment that further processes the basting pieces. .

When handed over automatically, the basting pieces are transferred via corresponding handover means and/or conveying means to a station in which, for example, further processing can be carried out or from which the basting pieces can be further conveyed. delivered to the station where the Deviations from exact alignment that occurred when cutting the (pre-)aligned textile are then inherited. Also during the handover process to the station, the basting piece may slip within the apparatus so that the basting piece is no longer correctly aligned. This precludes precise further processing of the basting piece, resulting in a product of inferior quality.

During manual transfer, the operator receives a basting piece from an upstream processing station or storage location and supplies it to the station in a manually (pre-)aligned state, but the manual position Alignment and positioning can be accomplished by an operator aligning the basting pieces by eye or with mechanical aids and placing them in the device. Inaccuracies in alignment and positioning can occur in the case of inexperienced unskilled workers, and also when skilled workers are careless, and the inability to process textiles in precisely aligned conditions. Disadvantages arise. This inaccuracy leads to the fact that the textile intermediates or final products produced in the process are of poor quality and therefore do not meet the standards.

Even if the basting pieces are handed over manually or automatically in an exact (pre)aligned state, the possibility of deviation from the exact alignment when the basting pieces are transported to the processing station. There is For example, a belt drive is used as the transport means, which transports the basting pieces on a transport plate past the device, which is particularly thick and/or flexible. In the case of textiles, the tacking pieces can slip in the conveying equipment, which can lead to the fact that correct alignment is not ensured during further processing.

The object of the present invention is a method and a device, in which and with the device the basting pieces supplied to the processing station are precisely aligned and of particular value in terms of quality. To create a method and apparatus by which it is ensured that a product can be manufactured while at the same time allowing individual alignment of basting pieces, such as textiles, which do not have outer edges and/or pile edges. be.

In order to solve the above problem, the invention proposes a method according to claim 1 .

The basting piece can be removed manually by the operator, for example from a front-mounted device part or from a storage location. Thereafter, manual (preliminary) alignment or positioning of the basting pieces in the apparatus, in particular before feeding to the station of the apparatus, takes place, and the operator subsequently manually feeds the basting pieces into the apparatus or station. .

Alternatively, the automatic (pre-)alignment or positioning of the basting pieces is, for example, a preceding device part in which the basting pieces are (pre-)aligned or positioned, followed by the device or It is possible in the parts of the equipment that are automatically supplied to the station. The station may be, for example, a transport station, which transports the basting pieces through the apparatus or performs any other task.

After the basting piece is supplied, the alignment and/or positioning of the basting piece is checked and corrections made if necessary. The inspection is preferably performed contactlessly, for example by sensor-based detection of markings on the basting piece. The markings are preferably provided on the surface of the basting piece, for example in the form of patterns, or in the weaving of textiles, for example in the form of yarn runs or weaving markings such as meshes, seams and the like. The markings may also be formed in the form of patterns formed by differences in weave, for example by different pile heights. The marking is preferably detected sensor-wise.

Sensor-based detection can be done with the human eye or via corresponding equipment. The detected marking layout is compared with a predetermined target marking layout. This is also optionally performed by a person or by suitable processing equipment, such as data processing equipment.

If the detection and comparison is done by the human eye of the operator, the target marking layout is for example displayed on or formed by the transport base on which the basting pieces are transported. It's okay. The operator recognizes the deviation of the basting piece layout from the target layout and specifies correction values. The operator can determine correction values empirically and transmit them to the correction station, e.g. Corrections are implemented.

If a deviation is recognized by the equipment, the recognized marking layout is e.g. transmitted to a processing station, which then performs a comparison with a target marking layout, which is preferably stored in the storage of the processing equipment. stored and available for comparison with the actual marking layout. If there is a deviation, the processing equipment calculates a correction specification, which is communicated directly to a suitable receiver of the correction station for automatic correction of the alignment by the correction station.

Alternatively, the calculated correction specification may also be displayed on a display panel, such as a monitor, so that the operator can read the specification and manually enter it into an operating element coupled to the correction station. can.

The correction equipment then performs corrections according to the correction values or correction specifications so that the marking layouts are at least approximately matched. The correction can be made, for example, by transmitting correction values or correction specifications to a control unit of a suitable machine element, which controls the machine element, which in turn sends the basting piece to the corresponding machine. Corrective action is applied to align the basting pieces in the correct position.

Such a post-modification of the marking layout and therewith of the basting pieces allows an exact positioning of the textile article in the device, thereby permitting an exact processing of the textile article in the processing station, which is particularly expensive and of good quality. products are produced.

In addition, the preferably non-contact inspection also enables registration of borderless basting pieces, thereby allowing individual and accurate alignment and positioning based solely on textile markings such as pattern or thread flow. It can be carried out.

When processing is followed, for example, by further processing steps in which the basting pieces must be correctly aligned, a new inspection and correction may be carried out and the individual , or multiple method steps may be repeated.

It is also provided that the method steps are performed during continuous or non-continuous transport of the basting pieces.

The basting pieces are conveyed through the apparatus by a conveying device. While being transported, the basting pieces can become misaligned within the apparatus, so that corrections during transport are advantageous, thereby re-aligning the basting pieces correctly before further processing stations. The steps of the method can preferably be performed while conveying the basting pieces through the apparatus on a continuous basis, thereby making the method economical to perform. Very high speeds of 20 meters per minute can then be achieved. However, if desired, non-continuous transport can also be provided.

The modification is preferably carried out immediately prior to the supply for processing and the execution of the processing steps.

This ensures that the basting pieces can be delivered accurately aligned to the processing station and processed in the processing station to produce a product of particularly good quality.

Preferably, a sensor device or camera comprising at least one sensor detects the markings on the basting piece, the sensor device or camera communicating with a computer, the computer storing the actual detected marking layout in the computer's storage. Comparing to the target marking layout obtained and providing correction specifications for automatic or manual correction if there are any deviations is done.

The basting pieces are conveyed using a conveying means past sensor devices or cameras, and at least one sensor or camera detects the pattern or thread flow of the basting pieces. Alternatively, a sensor device or camera can be conveyed past the basting piece. The sensor device or camera communicates with the computer and transmits detected data to the computer. The computer is connected to the storage and has access to the stored data, the storage stores at least one target marking layout, and the computer compares the actual marking layout with the target marking layout. If there is a deviation, the computer creates a corresponding correction specification and supplies the correction specification to implement the correction. The correction can be made automatically by transmitting the correction specification as a corresponding control signal to the correction station.

Alternatively, the correction can be made manually, the correction specification being displayed on a display panel, eg a monitor, read and subsequently entered into an operating element that communicates with the correction station.

A sensor device or camera is preferably provided to detect the actual path of deflection and the direction of deflection.

This creates an accurate marking layout. As regards the direction, for example, the deviation is detected to the left or to the right transversely to the transport direction. The path is likewise detected precisely, ie to what extent it deviates. The path may be identified in mm, for example. These images are compared to the target marking layout so that accurate revision specifications can be produced with corresponding dimensions.

Preferably a sensor detects the distance to the marking on the surface of the basting piece.

Deviations from the target marking layout can thereby be detected, for example, on the basis of the pile height or other ridge development on the surface of the basting piece.

Correction values and possibly correction specifications are preferably entered manually into the operating element, and alignment corrections are made in response to the inputs.

The operator can input the identified correction values into the operating elements to cause the alignment corrections to be made.

As long as a layout comparison has been made by the processing device and a revised specification has been generated, the revised specification can preferably be read from the display panel and entered into the operating element.

The operating element is preferably coupled to the correction station via a control unit, which controls the correction station in response to inputs to the operating element.

Preferably, the deviation and/or correction specifications are displayed on a display panel.

Correction specifications may be displayed on the display panel, for example in numerical or equivalent written form, and read at the display panel. This value is optionally used for manual correction by an operator entering the value into an operating element communicating with the correction station. Alternately or additionally, deviations may also be displayed, from which correction values can be determined.

Alternatively or additionally, it may be provided that the correction specification is directly communicated to the correction station, and the correction station carries out the correction automatically according to the correction specification.

This eliminates the need for human intervention and provides fully automatic correction of the alignment of the basting pieces. Operating elements and/or display panels may additionally be provided for safety in the event of failure of the automatic machine or for individual adjustment.

Preferably, corrections are made in both directions transverse to the conveying direction.

The basting pieces can shift in both directions transverse to the direction of transport, thereby requiring correction in both directions to achieve correct alignment.

The present invention also relates to a method for aligning plane regions or edge regions of a piece of material, preferably flexible, in particular a basting piece of textiles, in particular using a correction station according to claim 1. With respect to the method for manual or automatic correction, said piece of material is transported at least in the vicinity of the plane area or the edge area by means of a conveying device in the conveying direction, preferably parallel to the edge area, wherein , preferably pressed against a support member of the transport device and transported along the support member by means of the driven transport means of the transport device.

In the prior art, methods and devices are known for aligning edge regions of flexible material pieces, for example textile material pieces.

Under the term flexible material piece it is understood that not only textile material pieces but also material pieces made of plastic, paper or similar materials can be used.

In the prior art, machines are known in which a fibrous material web is registered and hemmed at the longitudinal edges of the fibrous material web. After hemming, the webs are aligned and divided into basting pieces of substantially rectangular shape. These basting pieces are then realigned using the edges of the basting pieces that have not yet been hemmed or folded back and transported by a corresponding transport device, the alignment being erroneously It is done for the purpose of allowing subsequent hemming and sewing of the edge regions without creating an appearance. A false appearance occurs when the outer edges of the basting pieces are not properly aligned. Alignment devices and methods in the prior art in which pile edges provided on a basting piece or material piece are raised above the plane of the material piece It is known to use pile edges as an alignment aid. Mechanical alignment means may be assisted by this pile edge to also align the pile edge with corresponding subsequent equipment required for e.g. hemming and sewing. However, without such pile edges, alignment is usually impossible or possible only with great difficulty.

For example, it is not sufficient to align the front end of the edge region of the material piece and then transport the material piece by means of a corresponding device, because the alignment position formed at the beginning of the material piece does not continue across the material piece, because the material piece is flexible and loses its alignment at the beginning when it is further conveyed by suitable equipment, thereby resulting in a high quality edge. formation is impossible.

Particularly flexible material pieces, when previously not yet separated from the material web, already provided with longitudinal hems and subsequently when the material piece is separated from the material web. To change the registration status to ensure high quality and accurate registration in the edge region in a flexible material piece, which is to be provided with a corresponding lateral hemming, presents a great deal of problems. However, such an alignment is a prerequisite for further processing, such as a corresponding basting piece, since mechanical hemming and mechanical hemming must possibly take place after said alignment. Only after completing these operations, the corresponding basting piece is completed. Mistakes in the prior alignment can result in poor quality basting pieces being completed and therefore not meeting the standard.

In order to ensure in a simple manner the correct formation of the flat areas or edge areas of a material piece in the form of a textile basting piece, a further development is proposed.

In the manner of the conventional method, the material pieces are first transported in the vicinity of the edge region with the aid of a transport device parallel to the edge region in the conveying direction. The conveying device may consist, for example, of a revolving conveying belt, which may continue in motion over further work stations of the manufacturing apparatus. When used according to the regulations, the transport belt is pressed against a support member, for example a support plate, and transported along the support member. The support plate forms a counter-support, whereby the edge region of the material piece is held between the transport means (transport belt) and the support member and is transported along the support member in the transport direction.

At this time, the following points are made for the solution according to the present invention. That is, when the alignment of a piece of material deviates closer to the conveying means from its target alignment, the area or edge area of the deviated aligned material piece moved away from the conveying means by an amount corresponding to a direction transverse to the conveying direction by a force, preferably a tensile force, acting towards or parallel to the plane to which the pieces are stretched, The alignment with the deviation of the material piece is thereby transferred to the target alignment.

A piece of material that is displaced in the conveying device in the direction of the conveying means can be drawn transversely to the conveying direction by forces acting mainly in the horizontal direction and can be aligned precisely.

The following points are then alternatively made for the solution according to the invention. That is, the edge regions of the material pieces are fixed in at least one second conveying device spaced from the conveying device and forming a free space with said conveying device and are conveyed together synchronously to align the material pieces. is deviated closer from the target alignment of the material piece towards the first conveying means, the area of the textile piece over which the at least one actuator is tensioned with a pressing force over the free space by which the textile piece is moved away from the first conveying means by an amount corresponding to a direction transverse to the conveying direction and transverse to the first conveying means, thereby causing a deflection of the material piece is transferred to the target registration.

The edge region of the material piece is secured within a second conveying device as it is conveyed through the apparatus. The second conveying device is preferably synchronized with the first conveying device so that the material pieces are uniformly conveyed through the apparatus. A free space is provided between the first conveying device and the second conveying device, and the material piece is stretched over the free space. As soon as the deviation of the material piece from the target alignment is confirmed, the actuator acts on the region with a pressing force, whereby the material piece is transferred to the target alignment until it is transferred to the first transport. Moved only across the device.

The following points are then alternatively made for the solution according to the invention. That is, the transport device or a mechanical member arranged on the transport device is provided with an alignment edge, or the support member forms the alignment edge, which is adjusted to the alignment status and the position of the material piece. When the alignment deviates from the target alignment of the material piece closer towards the transport means, the area or edge area of the deviated aligned material piece overlies the alignment edge. The alignment with the deviation of the material piece is pulled through and thereby moved away from the transport means by an amount corresponding to the direction transverse to the transport direction and transverse to the transport means, which is the target alignment is transferred to

In accordance with the present invention, registration edges are provided at suitable locations on the machine frame, conveying equipment, or other member of the overall apparatus and are utilized for the purpose of aligning the material pieces. The registration edge may be a stable edge. However, the alignment edge may also be provided in the form of a bar, elastically tensioned wire, or the like.

The support member itself may form the registration edge. Each registration edge is adjustable in a suitable position for targeting. As long as the material piece is aligned deviating from the target alignment, the material piece can be moved over the alignment edge, thereby moving transversely to the conveying direction and transversely to the conveying means. , whereby the alignment with the deviation of the material piece is transferred to the target alignment.

The concept of transverse does not mean orthogonal, it is sufficient, for example, if the tensile movement is directed obliquely, so that one part of the tensile force component is directed horizontally and one part of the tensile force component A further portion is oriented vertically. In any event, a sufficient degree of tensile force must be exerted on the material piece to move the material piece to the desired degree.

At this time, the following points are preferably performed. That is, the support member has at least one recess or alignment edge, and the deviation when the alignment of the material piece deviates from the target alignment of the material piece closer towards the transport means. The area or edge area of the material pieces aligned with each other extends over the alignment edge extending with respect to the conveying direction or extends with respect to the conveying direction and is adjacent to the conveying means. over the alignment edge of the recess, thereby moving away from the conveying means by an amount corresponding to a direction transverse to the conveying direction and transverse to the conveying means, thereby deviating the material pieces. Alignments with precision are transferred to exact target alignments.

In at least one of the projecting areas, preferably in both projecting areas, recesses or outer edges are provided which extend parallel to the conveying direction. A piece of material overlies, for example, a corresponding recess or outer edge. The user can then check the alignment of the edge regions of the material piece and act upon the material piece when the alignment of the material piece deviates from the correct target alignment of the material piece. Deviated aligned regions of a piece of material only if the edge region of the piece of material extends deviated closer to the conveying means from the exact target alignment or the edge region over the outer edge extending parallel to the conveying direction or over the outer edge of the recess extending parallel to the conveying direction and adjacent to the conveying means, Traversing the conveying direction and pulling in a direction transverse to the conveying means, thereby moving (pulling) away from the conveying means by a corresponding amount, thereby aligning the material pieces with an offset is transferred to exact target registration.

As soon as the target alignment has taken place, no tensile force acts on the edge region of the material piece and the material piece is transported further using only the transport means. Such an arrangement and alignment preferably takes place adjacent to the conveying means on both the left and right sides, so that on the one hand the tensile forces correspondingly acting on the edge regions and on the other hand correspondingly acting on the material pieces. A force balance is obtained, which results in accurate target alignment of the material pieces.

Preferably, the alignment edge is aligned parallel to the conveying direction.

Such alignment is not necessary, but is advantageous for carrying out the method.

Alignment is possible even with an alignment that is not exactly parallel, because the application of a corresponding force provides a balance, which finally ensures the desired alignment.

In addition, it is preferably provided that the tension is brought about by the action of a force directed at least approximately perpendicular to the strip material.

This is advantageous for accurate target alignment of the material piece.

During the application of a force, in particular a tensile force, the means applying said force or tensile force is in the conveying direction, at an angle to said conveying direction, preferably parallel to the conveying direction of the conveying means. It is very particularly provided that the strip material is moved in the direction of conveyance, preferably parallel to the direction of conveyance.

What is achieved here is that the alignment is not only performed point-wise within a narrow area, but also over a relatively large area extending substantially parallel to the conveying direction and during the conveying process However, the alignment can be discontinuous or continuous.

It is particularly preferred here that the movement or movement component of the means in the conveying direction is adapted to the conveying speed of the conveying means, thereby avoiding creases of the strip material.

When a piece of material has a sensorically or optically recognizable edge or outer edge, or a marking, line or step extending parallel to the conveying direction, and their alignment deviates from the target alignment, It may also be recognized by means of implementing or monitoring the method and used by activating technical means for precise target alignment of the material piece.

Regarding the device, the problem set above is solved by a device according to claim 20 .

The basting pieces are supplied to the station automatically, preferably via an upstream device part, or manually by an operator. The station has a conveying device connected to it or incorporated therein, and the station itself is a conveying device for receiving basting pieces, or as the case may be, so that the conveying device already starts in front of the station. Provision may be made so that the basting pieces can be transported from the station or past the station to a transport device connected to the station. The basting pieces are transported through the apparatus and into the processing station using a transport device.

Post-corrections of the basting pieces are made by the inspection station and the correction station so that the alignment of the basting pieces that have deviated from their target positions during delivery or while being conveyed through the apparatus is The piece is a processing station in which it has been modified before being fed to the processing station where the basting piece is processed. This ensures a particularly good quality of intermediate or final products.

The inspection station may be provided before the correction station, whereby first the inspection and then the correction are performed. Alternatively or additionally, an inspection station may be located downstream of the processing station, the inspection station inspecting the alignment of the processed basting pieces and, if there is deviation, subsequent basting pieces. create a modified specification or modified value for

The inspection station allows contactless detection of the marking layout, preferably sensor-based detection being carried out using the human eye or corresponding equipment. Alignment of the basting pieces can be checked at the outer edge because the edges are sensorically recognizable or, for textile basting pieces, at the pile edge, but detection should be based on markings such as patterns. Such an edge is not necessary, as it is also possible. At the inspection station, the previously detected marking layout is compared with the target marking layout and correction values or specifications are identified.

The correction values are supplied by a person during the inspection, who performs a comparison of the marking layout with the target marking layout and identifies which correction values should be set, for example based on empirical values.

Alternatively, the comparison is carried out by corresponding technical means for data processing and modified specifications are produced.

Alignment corrections are subsequently made by a correction station, which performs accurate registration of the basting pieces based on the correction values or correction specifications.

In the processing station intermediate or final products are produced with excellent quality. The processing station may be a brace in which the basting pieces are for example hemmed or sewn. However, any other processing steps may be performed.

The inspection station preferably comprises a detection device for sensor-wise detecting the actual marking layout, a marking layout coupled with the detection device and detected, and a target marking layout preferably stored in an electronic storage. and processing equipment for comparing, evaluating deviations, and possibly providing revised specifications.

The marking layout detected using the detection device is communicated to the processing device, which performs a comparison with the target marking layout. The processing device is therefore connected to a storage, in which at least one target marking layout is stored, and the processing device accesses data in the storage and compares the target marking layout with the marking layout.

When there is a deviation in the layout, the processing equipment computes and supplies a correction specification. The modified specification is then communicated and displayed on the display panel. The correction specification may alternatively be supplied as a corresponding control signal and transmitted directly to the control unit of the correction station.

The detection device preferably comprises a camera or a sensor device with at least one sensor.

A contactless recognition of the marking layout is possible with sensor devices or cameras.

It may be provided that the sensor is preferably an optical sensor or a sensor that performs a distance measurement.

An optical sensor can be used to optically detect the marking layout. At this time, for example, colors and patterns can be detected. However, different pile height type marking layouts on the surface of the basting piece may be detectable. A marking layout of that type can also be detected optically. Alternatively, this type of marking layout can also be detected via distance measurement. A distance measuring sensor is provided for this purpose, which detects the distance to the pile tip.

Preferably, the sensor is an optical sensor and the light source is positioned facing the sensor device or camera, and the basting piece is conveyed through the apparatus between the sensor device or camera and the light source. What is set is being done.

A light source is provided facing the sensor device or camera, the light source transilluminating the basting piece so that the sensor or camera can better recognize markings on the transmissible basting piece.

It may preferably be provided that the processing equipment comprises a computer with a storage and at least one target marking layout stored in the storage for comparison with the actual marking layout.

A different target marking layout can be stored in the computer, or a new target marking layout can be programmed later for a new production line. These are then selected according to the production line and made available for comparison with the detected corresponding marking layouts.

It is preferably provided that the correction station comprises and is controlled by a control unit coupled with operating elements for entering correction values and possibly correction specifications.

Correction values specified by the operator or correction specifications calculated by the processing device can be manually entered into the operating element, which transmits corresponding control signals to the control device. A correction station performs alignment corrections in response to the input.

The correction can be effected, for example, by suitable mechanical elements, the control unit controlling the mechanical elements according to the correction values or correction specifications, so that the mechanical elements exert a corresponding mechanical action on the basting piece. Make corrections by aligning the basting pieces in the correct position.

Preferably, the device has a display panel, which is coupled to the inspection station, on which the modified specifications supplied by the inspection station are displayed.

The display panel may be, for example, a monitor on which the correction specification is displayed and can be read so that the correction specification can then be entered into the operating element. This allows manual correction of the alignment of the basting pieces.

Alternatively or additionally preferably, the inspection station is coupled in direct communication with the correction station, and the correction specification is directly controlled by the correction station using signals generated by the computer of the inspection station. It may be done that is installed in the unit.

Thereby, automatic correction is performed according to the correction specification without human assistance.

The control means are adjusted from an open basic position to an active position in which the material piece is held clampingly in the control means. The control means are then adjusted transversely to the conveying direction with the area of the material piece exerting a force on the material piece until it is transferred to the target alignment.

It is then preferably provided that the device has control means on both sides of the transport device.

This arrangement allows alignment on both the left and right sides adjacent to the conveying means, thereby obtaining a balance between the forces correspondingly acting on the edge region on the one hand and the material pieces correspondingly on the other hand, Accurate target alignment of the material piece is thereby achieved.

Alternatively here with regard to the apparatus, in particular for carrying out the method according to claim 11 or 18 , the apparatus is provided at a distance to the conveying equipment and comprises a second conveying means.

Squeeze and also with the area of the piece of material that is stretched over the free space. While the first conveying device allows movement of the material piece, the material piece in the second conveying device is fixed such that the material piece is forced against the first conveying device by pressure acting on the region. It has been moved transversely to the transport direction and transversely to the plane and transferred to the target alignment.

It is then preferably provided that the device has a second conveying device and control means provided on both sides of the conveying device.

This arrangement allows alignment on both the left and right sides adjacent to the conveying means, thereby obtaining a balance between the forces correspondingly acting on the edge region on the one hand and the material pieces correspondingly on the other hand, Accurate target alignment of the material piece is thereby achieved.

By correspondingly configuring the registration edges, which may be formed by strips of material or wires or the like, the equipment necessary to achieve registration is made available. The support member itself may have registration edges. When positioning when deviating from the target alignment, the working position can be adjusted by the control means, after which the control means entrains the corresponding area of the material piece to align the material piece. let it happen

In this case, it can be expediently provided that the areas of the material piece which lie near the flat area or the edge area are clamped or can be clamped between the support element and the conveying means.

In addition, it is preferred that the length of the adjustment movement stroke of the control means from the basic position to the working position for the purpose of exact alignment of the edge region of the material piece is adjustable.

Preferably, it can also be provided that the support is fixed to the machine frame, to the support element, in an elastically pivotable manner.

A possible variant is that the control means are formed as a cleat, a roller or a stamp at their free end facing the material piece.

One preferred variant is that the control means is a driven roller or cylinder, or a belt drive with a driven roller and at least one freely rotating roller, or a belt drive with only freely rotating rollers. That is.

In this case, it is particularly advantageous if a frame-fixed rotary motor drive is provided as the drive for the control means, said rotary motor drive connecting means, in particular a drive belt or a gear wheel or a friction drive. It is provided that the drive shaft is mounted in a mounting block in a frame-fixed manner and that the control means is pivotably mounted about the drive shaft.

Advantageously, it is also provided that the control means are adjustable by means of actuators held on the frame.

Embodiments of the method according to the invention and of the device according to the invention are illustrated in the drawing and explained in more detail below.

Figure 2 shows the device in cross section in a second working position;

FIG. 1 shows a method for accurately positioning and processing a textile article, in particular a basting piece 1, comprising the following method steps:
a step 3 of mechanically or manually feeding the (preliminary) aligned and/or positioned basting pieces 1 to the device 2 or to a station 9 of said device 2;
step 4 of checking the alignment and/or positioning of the basting piece, preferably markings of the basting piece, preferably provided on the surface of the basting piece or in the weave of the basting piece; is sensor-wise detected and the actual marking layout is compared to the target marking layout;

4 schematically shows a method with optionally repeating individual method steps or multiple method steps.

The basting piece 1 can be manually removed by the operator, for example from a front mounted device part or from a storage location. The basting piece 1 is then manually aligned or positioned by an operator prior to feeding 3 into the station 9, who then manually transports the basting piece 1 into the station 9, or insert.

Alternatively, the automatic (pre-)alignment or positioning of the basting piece 1 can be, for example, a preceding device part in which the basting piece 1 is (pre-)aligned, followed by station 9. It is possible in a device part that is automatically transported or supplied to the .

After the basting piece 1 has been fed 3 into station 9 the alignment and/or positioning of the basting piece is checked at inspection station 11 and corrections 7 are made at correction station 12 if necessary.

To that end, the basting pieces 1 are conveyed by the conveying device 10 past the device 2, the steps of the method preferably progressing during the continuous or non-continuous conveying of the basting pieces. Whilst the inspection 4 and correction 7 while the basting piece 1 passes through the device 2 is particularly advantageous, it is possible that the basting piece 1 may be displaced, especially during transport, and the basting piece 1 may be displaced prior to processing. Correction 7 may be required prior to delivery 8 to processing station 13 and execution of processing steps for accurate alignment. Continuous conveying allows a particularly economical implementation of the method and speeds of 20 m per minute can be achieved.

Alternatively, the inspection 4 of the basting piece 1 is performed only after processing in the processing station 13 . The course of this process is not shown in FIG. Deviations of the markings from the target marking layout, e.g., seams provided during machining, are detected after machining, correction specifications or correction values are identified, and the Correction specifications or correction values are communicated to correction station 12 . The correction station 12 then carries out corresponding corrections for the subsequent basting piece 1 so that the subsequent basting piece 1 is correctly aligned before feeding 8 to the processing station 13 .

The inspection 4 is performed contactlessly, for example by optical detection of the markings on the basting piece 1 . The markings are preferably provided on the surface of the basting piece, for example in the form of a pattern, or in the weaving of textiles, for example in the form of yarn runs or weaving markings such as meshes, seams, etc., and are detected optically. However, other detection elements can also be provided which can detect the markings in a contactless manner. It is also possible, for example, to detect markings of different pile height types by distance measurement. For this purpose, a sensor can be provided that carries out a distance measurement, which sensor detects the distance to the pile tip. If no deviation was detected during the test 4, no correction 7 is necessary and the method proceeds according to the dotted line Y, so that after the test 4 the supply 8 to the processing station 13 takes place.

Optical detection can be done with the human eye or via corresponding optical instruments. The optically detected marking layout is compared with a predetermined target marking layout. This is also optionally performed by a person or by suitable processing equipment 15, preferably data processing equipment.

When detection and comparison are to be performed by the human eye of the operator, the target marking layout is for example displayed on or formed by the transport base on which the basting piece 1 is transported. It can be. However, any other suitable implementation is possible in which a person can visually compare the marking layout with the target marking layout. The operator recognizes the deviation of the basting piece layout from the target layout and specifies correction values. The operator can specify correction values empirically and transmit them to the correction station, preferably via manual input to an operating element 20 associated with the correction station 12, so that the correction values are determined accordingly. A manual correction 7 is performed. Recognition by the optical device is preferably effected by a sensor device 17 comprising at least one sensor or by a camera, the basting piece 1 being conveyed by means of the conveying device 10 past the sensor device 17 or the camera and being basted. The markings on the piece 1 are detected optically.

A sensor device 17 or camera preferably detects the actual path of deflection and the direction of deflection, thereby confirming the correct marking layout. As regards direction, it is detected whether the deflection is to the left or to the right in a direction transverse to conveying direction 23 . The path is also detected precisely, ie how much deviation there is. The path may be identified in mm, for example. These images are then compared to the target marking layout so that accurate revision specifications can be made with corresponding dimensions.

The sensor device 17 or camera communicates with the processing device 15 and the detected marking layout is communicated to the processing device. The processing device 15 preferably comprises a computer 19 and a storage 16 coupled to the computer, in which at least one target marking layout is stored, with which the target marking layout and the actual marking layout are compared. be. A number of different target marking layouts may be programmed and stored in storage 16, which target marking layouts may be selected for comparison depending on the product item or production line.

If there is a deviation, the computer 19 creates a corresponding correction specification and supplies it for carrying out the correction 7 . The modification 7 can then be made automatically by transmitting the modification specification as a corresponding control signal to the modification station 12, which automatically implements the modification 7 according to the modification specification, thereby No human intervention is required and a fully automatic correction 7 of the alignment of the basting piece 1 takes place.

Alternatively, the calculated correction specification may also be displayed on a display panel 22, such as a monitor, so that the operator can read it and enter it into an operating element 20 that communicates with the correction station 12. can. The revision specification may be displayed in numerical or equivalent written form, for example, and read by the operator. The operating element 20 is preferably coupled to the correcting station via a control unit 21 of the correcting station 12 , the control unit 21 controlling the correcting station 12 as a function of inputs to the operating element 20 .
The operating element 20 and/or the display panel 22 can additionally also be used in automatic corrections 7, in which the control signals are led directly to the correction station 12, for example in the event of a failure of the automatic machine. It may be provided for safety or for individual adjustment.

The correction station 12 subsequently performs corrections 7 according to the correction values or according to the correction specifications, whereby the marking layout has been brought into conformity.

The correction 7 can preferably be made by transmitting 6 the correction values or correction specifications to the control unit 21 of the suitable machine member, the control unit 21 adjusting the machine member according to the correction specifications or according to the correction values. The machine member carries out the correction 7 by exerting a corresponding mechanical action on the basting piece 1 to bring the basting piece 1 into the correct position. The corrections 7 are made in both directions transverse to the conveying direction 23, since the basting piece 1 can deviate in both directions transverse to the conveying direction 23 and corrections 7 are required in both directions. Only then can an exact alignment be achieved. Such a post-modification of the marking layout and therewith of the basting piece 1 enables a correct positioning of the basting piece 1 in the device 2 and thus a correct processing of the basting piece 1 in the processing station 13. , resulting in particularly expensive quality products. Therefore, preferably inspection 4 and correction 7 are carried out immediately before the processing step, so that the basting piece 1 is supplied to the processing station in correct alignment.

In addition, the non-contact sensor inspection 4 also enables alignment of edgeless basting pieces, whereby the fibers, such as yarn flows, can be detected on the basis of the pattern alone, or in the case of textile basting pieces 1 . Individual and accurate alignment and positioning can be achieved based on product markings alone. The processing of the basting piece 1 can be done in any way, for example a hem can be sewn or the basting piece 1 can be folded. If processing is followed, for example, by further processing steps in which the basting piece 1 must be correctly aligned, a new check 4 and correction 7 can be performed, The steps of the method can be repeated any number of times.

FIG. 2 shows a schematic configuration of an apparatus 2 for carrying out the method according to claim 1, the apparatus 2 comprising:
a station 9 to which the basting piece 1 is supplied manually or mechanically (pre)aligned and/or positioned;
a conveying device 10 for conveying the basting piece 1 past the apparatus 2, possibly starting before the station 9, connected to the station 9;
an inspection station 11, at which the actual marking layout of the markings of the basting piece 1 is detected, preferably sensor-wise, and can be compared with a target marking layout and whether correction values or correction specifications are produced; , an inspection station that can be created, and
a correction station 12 for precisely aligning the basting piece 1 according to a correction value or specification;
It comprises a processing station 13, preferably a fixture in which the basting pieces 1 are fed in correct alignment and can be processed.

The basting pieces 1 are supplied to the station 9 in a (pre-)aligned state, either automatically, preferably from an upstream device part, or manually by an operator.

A transport device 10 is connected to the station 9, the station 9 itself being a transport device 10 and supplied with basting pieces 1, or possibly the transport device 10 already being in the station 9. so that the basting piece 1 can be transported from the station 9 or past the station 9 to a transport device 10 connected to the station. good.

The station 9 may for example be any other station 9 for performing processing steps.

The basting piece 1 is conveyed by means of a conveying device 10 through the apparatus 2 past an inspection station 11 and a correction station 12 or through an inspection station and a correction station into a processing station 13 . The inspection station 11 may alternatively be provided downstream of the processing station 13, which is not shown in the figures. In this case, the inspection 4 is performed only after the first basting piece 1 has been processed. As far as deviations from the target layout are detected, the correction specifications or values are transmitted to a correction station 12, which precedes the processing station 13, so that alignment corrections are made prior to processing. A post-correction of the basting piece 1 is performed by an inspection station 11 and a correction station 12, thereby aligning the basting piece 1 that has deviated from its target position during delivery or while being conveyed through the apparatus 2. is modified before it is fed to a processing station in which the basting piece 1 is processed into an intermediate or final product at processing station 13 . This ensures a particularly good quality of intermediate or final products.

FIG. 3 shows a first variant of device 2 . The inspection station 11 makes it possible to detect the marking layout contactlessly. The inspection station 11 has for that purpose a detection device 14, which is a camera or a sensor device 17 with at least one optical sensor. The layout of the basting piece 1 can thereby be detected and, since the edges are optically recognizable, outer or pile edges on which alignment can be performed. An outer edge or pile edge is not necessarily required, although detection of the pile edge is also possible, since optical detection based on arbitrary patterns and such markings is also possible. Alternatively, markings can also be detected by distance measurement. A distance measuring sensor is provided for this purpose, which detects the distance to the pile tip. Afterwards, in the processing equipment 15 of the inspection station 11, which processing equipment is coupled to the detection equipment 14, the comparison of the detected marking layout with the target marking layout and the identification 5 of the correction specification takes place. This is done by corresponding technical means for data processing, in the embodiment a computer 19 connected to a storage 16 is used. The marking layout detected using the camera or sensor device 17 is transmitted to the processing device 15 or a computer 19 contained therein. The computer 19 then performs a comparison of the marking layout with a target marking layout stored in the storage 16, which may store a different target marking layout, or a new marking layout for a new production line at a later time. target marking layout can be programmed. These are then selected according to the production line and made available for comparison with the detected corresponding marking layouts.

Corrective specifications are calculated by the computer 19 when the marking layout has deviations from the target marking layout. The correction specification is transmitted to the receiving part of the correction station 12 through corresponding technical means, and the correction station makes corrections 7 according to the specification.
The correction specification is transmitted to the control unit 21 of the correction station 12, for example in the form of control signals of the computer 19. FIG.

In this case, inspection station 11 is coupled in direct communication with correction station 12 . Accurate corrections 7 are thereby performed automatically according to the correction specifications without human assistance.

The correction 7 can, for example, be performed by means of suitable mechanical elements, the control unit 21 controlling the mechanical elements according to the correction specifications, which mechanical elements exert a corresponding mechanical action on the basting piece 1. Correction 7 is carried out by and basting piece 1 is aligned in the correct position.
If there is no deviation, no correction 7 is made.

The basting piece 1 is subsequently supplied to the processing station 13 . The processing station 13 may be a brace in which the basting piece 1 is for example hemmed, glued or sewn. However, it may also be a device for folding the basting piece 1 or for performing any other processing step.

In the processing station 13 intermediate or final products are produced with excellent quality.

A second variant of the device 2 is shown in FIG. The detection of the marking layout and the comparison with the target marking layout are performed by human eyes in the inspection station 11 .

The comparison is for example that the target marking layout referred to for comparison is a transport base, on which the basting piece 1 is transported, displayed on or formed by the transport base. performed by The operator recognizes the deviation of the basting piece layout from the target layout and specifies correction values. Correction values can be empirically determined by the operator and transmitted to the correction station 12 via manual input to an operating element 20 coupled to the correction station 12, so that a manual Equation modification 7 is implemented. The correction station 12 has an operating element 20 for that purpose.

A third variant is shown in FIG. The detection and comparison are performed in the same way as in the first embodiment, i.e. in the inspection station 11 by the detection equipment 14 (e.g. sensors) and the processing equipment 15, the computer 19 of the processing equipment 15 being coupled with the display panel 22. The modified specifications are transmitted to the display panel 22 and the modified specifications are displayed on the display panel 22 . The displayed revision specification is read and manually entered into the operating element 20 associated with the revision station 12 . The correction station 12 has a control unit 21 coupled to the operating element 20 and is controlled by the control unit in response to inputs.

A fourth variant is shown in FIG. In this figure, detection is performed using a sensor of a sensor device 17, and a light source 18 is provided so as to face the sensor. As the basting piece 1 is transported past the device 2 it is provided between a sensor device 17 and a light source 18 and is transilluminated by the light source 18 so that the sensor detects the basting piece 1, e.g. markings in the weave of the fibers can be better recognized.

The methods and apparatus described above are used to treat not only textile basting pieces, but also basting pieces made of any material that can be processed in the same manner as textile materials. These include, for example, basting pieces made of paper or plastic.

A further device, shown in FIGS. 7-11, serves to align the edge region 101 of the preferably flexible piece of material 102 . The device can be used, for example, as a correction station 12 for precise alignment within the device 2 . The material piece 102 is in particular a textile material piece, separated from the fiber web and having a quasi-rectangular basic shape. The apparatus consists essentially of a conveying device 103 with an implied machine frame 104 for the material pieces 102, comprising a driven conveying means 105, for example a conveying belt, and a support member 106 for the conveying means 105. Become. In an embodiment, support member 106 is formed as a plate. A piece of material 102 is placed on the plate. A transport means 105 in the form of a belt drive is placed above the material piece 102 , whereby the material piece is pressed against the support member 106 . Support member 106 is preferably a flat, smooth plate. The transport means 105 , which are preferably formed as transport belts of a belt drive, are combined on the upper side with a spring-loaded support block 107 , which moves the transport means 105 towards the support member 106 elastically. press under a positive prestress. These support blocks 107 are held by components of the machine frame 104 . The visible part of the machine frame 104 is formed as an L-folded metal sheet with one leg oriented parallel to the elongation of the support member 106 and the other leg oriented parallel to the extension of the support member 106 . The legs are oriented perpendicular to the elongation of the support member.

A region of the material piece 102 near the edge region 101 of the material piece 102 is held clampably between the support member 106 and the conveying means 105 or can be clamped and conveyed. It is conveyed parallel to the edge region 101 in the conveying direction 108 by the means 105 . As best seen in FIGS. 7-11, in order to clarify the alignment problem, the edge region 101 is formed to extend in a pseudo-wavy shape, whereby the edge region is shaped like a carrier. It is not aligned exactly parallel to the direction and has a different shape to the direction of transport and extends at different distances from the transport means 105 .

The support members 106 project from the transport means 105 on both sides transversely to the transport direction. Protruding regions are described by 109 or 110 . In an embodiment recesses 111, 112 are provided in both protruding regions 109, 110 with outer edges 113, 114 oriented parallel to the conveying direction 108, said outer edges respectively next to. Alternatively, it is also conceivable that one outer edge 115, 116 of each projecting region 109, 110 of the support member 106 is used accordingly, said outer edge 115, 116 also being oriented parallel to the conveying direction 108. ing. Furthermore, on the outer edge 113 or 114, or possibly also on the outer edge 115 or 116, respectively, one control means 117, 118 is fixed indirectly to the machine frame 104, said control means being in the basic position. , for example shown in FIGS. 7, 9 and 10, outside the plane in which the acting members of the control means in their basic position are spanned by the gap between the support member 106 and the conveying means 105; In an embodiment it is adjustable from a basic position above the plane into a working position, which is shown in FIGS. 8 and 11, in which the control means press against the plane and That is, it is positioned under the protruding regions 109 or 110 quasi-by the member.

The control means 117 or 118, during adjustment movements transversely to the conveying direction 108 and transversely to the above-mentioned planes, control the outer edge 113 or 114, or It is also moved past 115 , 116 with the area of the material piece 102 having a relatively small distance to the perimeter and next to the conveying means 105 .

Thus, depending on the alignment required, the control means 117 or 118 can be used to align the edge region 101 or the edge region 101a beyond the transport means 105 . When the control means 117 moves from the position shown in FIG. 7 to the position shown in FIG. 8 or from the position shown in FIG. 10 to the position shown in FIG. is exerted, which lateral force moves the material pieces 102 in the area of engagement with the control means 117, 118 away from the conveying device 103, thereby positioning the edge area 101 exactly as desired. Align.

In order to ensure that the material piece 102, in particular the edge of the material piece 102, is entrained during the adjusting movement of the control means 117, 118 from the basic position into the working position, the support member 106, in the stroke of the control means 117, 118: Moreover, in the region of the recesses 111, 112 and on the outer edge of these recesses forward in the conveying direction, a pivotable support 119 is held, which during the adjustment movement into the working position the control means 117 , 118 presses against the support and pushes it downwards, for example transversely to the conveying direction, as can be seen in FIG. The edge region 101 of the material piece 102 provided in between is fixed between the control means 117, 118 and the support 119 so that, as clarified on the basis of FIG. is moved downwardly transversely to the conveying direction 108 as desired. For the purpose of precisely aligning the edge regions 101, 101a of the piece of material 102, the length of the stroke of the adjustment movement of the control means 117, 118 from the basic position to the working position can be adjusted, for example by the operator, and Depending on the deviation of the outer edges of the edge regions 101, 101a from the desired position, a larger or smaller adjustment travel is carried out by .

The support 119 is in particular elastically and displaceably fixed to the support member 106 , in particular to the outer edges of the recesses 111 , 112 forward in the conveying direction 108 .

This achieves that during the adjusting movement of the control means 117, 118, the support 119 is moved automatically according to the adjusting movement stroke.

It is not shown in the figures that the control means 117 , 118 are formed as cleats, rollers or stamps at their free ends facing the material piece 102 . This is a possible configuration. However, it is then assumed that the actuation of the control means, i.e. the adjustment movement of the control means from the basic position to the active position, has to be performed intermittently, so that during the transport of the material piece 102 in the transport direction 108: The edge regions 101, 101a respectively under the control means can be pulled accordingly by the control means, thereby achieving a precise alignment.

It is then preferably provided that the control means is a belt drive 120, 121 comprising a driven roller 122 and a freely rotating roller 123, the belts of the belt drive 120 or 121 moving around the rollers. circling and being moved.

As drive for the driven rollers 122 of the control means 117, 118, a motorized rotary drive 124 is held and fixed to a frame member, for example a member of the machine frame 104, which motorized rotary drive is coupled. Means 125 , in the exemplary embodiment a drive belt, are connected to a drive shaft 126 . The drive shaft 126 additionally has rollers 127 fixedly connected to the shaft for this purpose. The drive shaft 126 is supported and guided in a mounting block 128 which is also fixed to a member of the machine frame 104 in a frame-fixed manner. The drive shaft 126 is fixedly connected to the driven rollers 122 of both control means 117 , 118 , thereby moving the belt drives 120 , 121 via rotation of the drive shaft 126 . The direction of rotation of the coupling means 125 (of the drive belt) is indicated at 129 . Additionally, the control means 117 , 118 can be adjusted by means of actuators 130 fixed to the machine frame 104 . The actuator 130 for this purpose consists, for example, of an electric motor drive 131 which can be actuated alternately exclusively in the right and left direction. Via the output shaft 132 a disk-shaped driver 133 is caused to rotate clockwise or counterclockwise in a defined manner about the axis formed by the output shaft 132 . In this driver, components 138, 139 of control means 117, 118 are pivotable about drive shaft 126 via connecting rods 134, 135 and connecting rods 136, 137. FIG. By rotating the driver 133 in one direction (e.g. clockwise) by means of the drive 131, the entire element with the belt drive is pivoted from the basic position into the active position so that the control means 117 is brought into the active position. The adjusted roller 123, which is free to rotate in its working position, is adjusted downwards, as can be seen, for example, in FIG. This movement of the driver 133 lifts the control means 118 on the other side. If the direction of rotation of the driver 133 is reversed, the control means 117 is lifted while the control means 118 is likewise lowered and the roller 123 rotating freely in said control means is moved downwards. With this arrangement, both control means 117, 118 cannot act on a piece of material at the same time, and only a respective selected control means 117, 118 acts on a piece of material, as should be determined by the user. guaranteed to be possible.

In order to perfectly guide the edge regions 101, 101a of the material piece 102 in the conveying direction 108 even after passing through the recesses 111, 112, one oblique guide follows each of the recesses 111, 112. A section 140 is provided, which guide section transitions steplessly in the conveying direction into the region following the projecting region 109 or 110 of the support member 106 .

In an embodiment, the control means 117, 118 are formed by circulating actuators, in particular belt drives 120, 121, in the same direction with respect to the conveying direction 108, the circulating actuators having at least the corresponding control means in the basic position. When it is to be moved from to the working position, and continuously during the working position, it is continuously driven in a circulating manner. The processing of the edge regions 101, 101a is thereby adapted to the transport direction and the transport speed of the material piece 102, thereby achieving the alignment of the edge regions 101 or 101a in the correct manner.

The positions of the edge regions 101, 101a that deviate from the target position can be visually detected by the operator so that the operator can activate the corresponding equipment accordingly. However, the edge area 101, 101a or the outer edge of the edge area is detected with a suitable detection device as regards the position of the edge area and the corresponding mechanical control actuates the control means 117, 118 accordingly. It is also conceivable and possible.

The apparatus shown in Figures 7 to 11 is suitable and defined for enabling a method for aligning the edge regions 101, 101a of a piece of material 102, in particular a basting piece of textile. To this end, the material pieces 102 are transported in the conveying direction 108 parallel to the edge regions 101, 101a by means of a transport device, for example a transport means 105. As shown in FIG. The material piece is then pressed against a supporting member 106 of the conveying device 103 by means of the driven conveying means 105 of the conveying device 103 and transported along the supporting member 106 in the conveying direction.
