Description

The present invention relates to a method and apparatus for accurately positioning and processing textiles, etc., in particular sewn pieces.

A method and corresponding device in the prior art, for example a textile material such as a fibrous web or textile sewn piece is manually or automatically (pre-)aligned and, for example, processed in a correspondingly aligned manner. It is known to be provided in steps or in the transport equipment of the device. The transport equipment transports the textile article through the apparatus to various processing stations.

With such a method and a corresponding device, not only textile sewn pieces, but also sewn pieces made of any material that can be processed in the same way as the textile material are handled. They also include sewn pieces made of paper or plastic, for example.

For example, automatic (preliminary) alignment of fibrous webs is known, in which the fibrous web is precisely aligned prior to processing, such as cutting the web into sewn pieces.

Alignment of the fibrous web is done mechanically, for example by mechanically interrogating the outer edges or pile edges of the textile article with respect to the segmented alignment rails. At this time, the position adjustment rail sets accurate alignment.

In order to be able to perform such mechanical alignment, the fibrous web must have edges that can be detected by the alignment rails so that the web can be pulled to the desired position. .. This has the disadvantage that this type of alignment cannot take place without outer edges or pile edges, for example depending on the pattern or the flow of the thread or mesh. Furthermore, the textile must be endless, as is the case with fibrous webs. This type of alignment is not possible with textile tack pieces.

After accurately aligning the fibrous web, the tack piece can be accurately cut. The sewn piece is then subjected to further processing, for example hemming, folding and/or sewing, and each sewn piece is delivered either automatically or manually to a device part for further processing the sewn piece. ..

When delivered automatically, the tacking piece is a station via corresponding delivery means and/or transporting means, for example, where further processing can take place at the station, or the tacking piece is further transported from the station. Handed over to the station. At this time, the deviation from the accurate alignment generated when the (preliminary) aligned fiber product is cut is succeeded. Even during the delivery process to the station, the tacking piece may slip in the device, so that the tacking piece is no longer correctly aligned. This prevents accurate further processing of the sewn piece, resulting in a poor quality product.

During manual delivery, the operator receives the sewn piece from a pre-positioned processing station or storage location and supplies it to the station in a manually (preliminarily) aligned position, but with a manual position. The alignment and the positioning can be performed by an operator by visually observing the provisional stitching piece or by using a mechanical assisting means and providing it in the apparatus. Inexperienced unskilled workers and inadequate skilled workers can cause inaccuracies in alignment and positioning, which prevents the textile product from being machined in an accurately aligned state. Disadvantages arise. This inaccuracy leads to inferior quality of the fiber intermediate product or final product made in the process and thus to failure of the criteria.

Even if the sewn piece is delivered manually or automatically in the correct (preliminary) aligned position, there is a possibility that the sewn piece will deviate from the correct alignment when it is transferred to the processing station. There is. For example, a belt drive is used as the transport means, which transports the sewn piece through the device on the transport plate, which is particularly thick and/or flexible. In the case of textiles, the tacking piece may slip within the carrier and may cause an incorrect alignment during further processing.

The subject of the invention is a method and a device, in which and with the aid of which the tacking piece supplied to the processing station is precisely aligned, which is of particular value in terms of quality. By creating a method and a device in which the product can be manufactured and at the same time it is ensured that the individual alignment of the sewn pieces, such as textiles without outer edges and/or pile edges, is possible is there.

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

The sewn piece can be manually removed by the operator, for example from a machine part in front or from a storage location. Thereafter, the manual (preliminary) alignment or positioning of the tacking piece is carried out in the device, in particular before it is fed to the station of the device, and the operator subsequently feeds the tacking piece manually to the device or station. ..

Alternatively, the automatic (preliminary) alignment or positioning of the sewn piece may be performed, for example, in a preceding device part, in which the sewn piece is (preliminarily) aligned or positioned, and subsequently the device or This is possible in the part of the equipment that is automatically fed to the station. The station may be, for example, a transfer station, which transfers the sewn piece through the device or performs any other task.

After the tacking piece has been supplied, the registration and/or the positioning of the tacking piece are checked and, if necessary, corrected. The inspection is preferably carried out in a non-contact manner, for example by sensory detection of markings on the tacking piece. The markings are preferably provided on the surface of the sewn piece, for example in the form of a pattern, or in the weaving of textiles, for example in the form of a weaving thread flow or in the form of a weaving marking such as a mesh, a seam. The markings may also be made in the form of patterns that are formed by differences in weaving, for example different pile heights. The markings are preferably detected sensorily.

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

If the detection and the comparison are done by the eyes of the operator, the target marking layout is, for example, the transport base, on which the tacking pieces are displayed or formed by the transport base. You can stay. The operator recognizes the deviation of the piece layout for provisional stitching from the target layout and specifies the correction value. The operator can specify the correction value on the basis of the empirical value and transmit it to the correction station, for example via a manual input to an operating element connected to the correction station, whereby a manual operation according to the correction value is possible. Modifications are implemented.

If the deviation is recognized by the machine, the recognized marking layout is communicated, for example, to a processing station, which then carries out a comparison with the target marking layout, which is preferably stored in the storage of the processing machine. It is stored and made available for comparison with the actual marking layout. If there is an excursion, the processing device will calculate a correction specification and the correction specification will be communicated directly to a suitable receiver of the correction station for automatic correction of the registration by the correction station.

Alternately calculated modified specifications may also be displayed on a display panel, such as a monitor, which allows an operator to read the specifications and manually enter them into an operating element associated with the modification station. it can.

The modifying device then carries out a modification according to the modification value or the modification specification, whereby the marking layouts are at least approximately matched. The correction can be effected, for example, by transmitting a correction value or a specification to a control unit of a suitable machine element, which controls the machine element, which machine element corresponds to the sewn piece. The correction is carried out by exerting a mechanical action to bring the tacking piece into the correct position.

Such a marking layout and thus also a post-correction of the sewn piece allows for the precise positioning of the textile in the device, which allows the textile to be accurately machined in the processing station, which is particularly expensive and of good quality. Goods are produced.

In addition, preferably non-contact inspection also enables alignment of rimless sewn pieces, which allows individual and precise alignment and positioning based solely on textile markings such as handle or thread flow. It can be carried out.

A new inspection and modification may be performed after the machining, for example when a further machining step is followed by a further machining step in which the tacking piece needs to be accurately aligned. , Or multiple method steps may be repeated.

The above problem is alternatively solved by the method according to claim 2.

The sewn piece may be manually removed by the operator, for example from a machine part in front or from a storage location and manually fed to the device. Prior to feeding the device, in particular the station of the device, a manual (preliminary) alignment or positioning of the tack pieces is performed.

Alternatively, the sewn piece can be automatically (pre-)aligned or positioned and subsequently automatically fed to the device or station. The station may be, for example, a transfer station, which transfers the sewn piece through the device or performs any other task.

After the first piece for provisional sewing is supplied, the first piece for provisional sewing is processed in the processing station. The alignment and positioning of the first tack piece is then inspected. To the extent that deviations from the target marking layout are identified during inspection, correction values or specifications are identified and the correction values or specifications are communicated to a correction station in front of the processing station. Thereafter, the subsequent sewn piece, which is conveyed past the device, is aligned according to the correction values or specifications before being supplied to the processing station. As a result, the subsequent piece for provisional stitching is accurately aligned with the processing step, and a product of high value in terms of quality can be manufactured.

The inspection is preferably carried out in a non-contact manner, for example by sensory detection of markings on the tacking piece. The markings are preferably provided on the surface of the sewn piece, for example in the form of a pattern, or in the weaving of textiles, for example in the form of a weaving thread flow or in the form of a weaving marking such as a mesh, a seam. The markings may also be made in the form of patterns that are formed by differences in weaving, for example different pile heights. The markings are preferably detected sensorily.

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

When the detection and comparison are performed by the operator's eyes, the operator recognizes the deviation of the temporary sewing piece layout from the target layout and specifies the correction value. The operator can specify the correction value on the basis of the empirical value and transmit it to the correction station, for example via a manual input to an operating element connected to the correction station, whereby a manual operation according to the correction value is possible. Modifications are implemented.

Alternatively, the detection and comparison can be recognized by the instrument, the detected marking layout being transmitted to, for example, a processing station, which then carries out a comparison with the target marking layout. The target marking layout is preferably stored in the processor's storage and is available for comparison with the actual marking layout. If there is a deviation, the processing device calculates a modified specification and the modified specification is transmitted directly to a suitable receiver of the modification station, which allows the modification station to automatically align the subsequent sewn piece. Corrections can be made.

Alternately calculated modified specifications may also be displayed on a display panel, such as a monitor, which allows the operator to read the specifications and manually enter them into the operating elements associated with the modification station. it can.

The correction device performs the correction according to the correction value or the correction specification, so that the marking layouts are at least approximately matched. The correction can be effected, for example, by transmitting a correction value or a specification to a control unit of a suitable machine element, which controls the machine element, which machine element corresponds to the sewn piece. The correction is carried out by exerting a mechanical action to bring the tacking piece into the correct position.

Such a post-correction of the marking layout and with it the subsequent sewn piece allows for the accurate positioning of the textile within the device, which allows for the accurate machining of the subsequent textile within the processing station, A particularly expensive quality product results.

In addition, preferably non-contact inspection also enables alignment of rimless sewn pieces, which allows individual and precise alignment and positioning based solely on textile markings such as handle or thread flow. It can be carried out.

After processing, new inspections and modifications may be performed, and individual or multiple method steps may be repeated.

Preferably, the method steps are performed during a continuous or discontinuous transfer of the sewn piece.

The tacking piece is transported by the transporting device so as to pass through the device. During the transport, the sewn piece can be displaced in the device, so that the correction during the transport is advantageous, so that the sewn piece is newly and accurately aligned before the further processing station. The method steps can preferably be carried out during the continuous transport of the sewn piece through the device, which makes the method economical to carry out. At this time, a very high speed of 20 m per minute can be achieved. However, if necessary, discontinuous transfer can also be performed.

Preferably, the modification is carried out just before the supply for processing and the execution of the processing steps.

This ensures that the sewn piece can be accurately aligned and fed to the processing station where it is processed and a product of particularly good quality can be produced.

Preferably, a sensor device or camera comprising at least one sensor detects markings on the sewn piece, the sensor device or camera communicates with the computer, the computer storing the actually detected marking layout in a computer storage. The target marking layout is compared with the target marking layout, and if there is a deviation, a correction specification for automatic or manual correction is provided.

The tacking piece is transported by means of the transporting means so as to pass through the sensor device or the camera, and at least one sensor or camera detects the pattern or the thread flow of the tacking piece. Alternatively, the sensor device or camera can be transported past the tack piece. The sensor device or the camera communicates with the computer and transmits the detected data to the computer. The computer is connected to the storage and can access 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 an excursion, the computer creates a corresponding amendment specification and supplies the amendment specification to implement the amendment. The modification can be done automatically by transmitting the modified specification to the modification station as a corresponding control signal.

Alternatively, the modification can be done manually, and the modification specification is displayed and read on a display panel, such as a monitor, and subsequently input to an operating element in communication with the modification station.

Preferably a sensor device or camera is used to detect the actual path of the excursion and the direction of the excursion.

This creates an accurate marking layout. In terms of direction, for example, a deviation is detected on the left or right side in the direction transverse to the transport direction. The path is likewise detected exactly, that is to say how much the deviation is. The path may be identified in mm, for example. These images are compared to the target marking layout, which allows accurate revision specifications to be created with corresponding dimensions.

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

The deviation from the target marking layout can thereby be detected, for example, on the basis of the pile height or the transition of other ridges on the surface of the tacking piece.

Preferably, the correction value and possibly the correction specification are manually input to the operating element, and the alignment correction is made in response to the input.

The operator can input the specified correction value to the operation element to cause the position adjustment to be corrected.

As long as the layout comparison is performed by the processing device and the modified specification is created, the modified specification can be preferably read from the display panel and input to the operation element.

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

Preferably, the excursions and/or modified specifications are displayed on the display panel.

The modified specifications may be displayed on the display panel, for example, numerically or in the form of the equivalent description, and read on the display panel. This value is optionally used for manual correction by the operator entering it into an operating element in communication with the correction station. Alternatively or additionally, the deviation may also be displayed, from which the correction value can be identified.

Alternatively or additionally, preferably, the modification specification may be directly transmitted to the modification station, and the modification station automatically performs the modification according to the modification specification.

This eliminates the need for human intervention and provides a fully automatic correction of the position of the sewn piece. The operating elements and/or the display panel can additionally be provided for safety in case of failure of the automatic machine or for individual adjustment.

Preferably, the correction is done in both directions so that it is transverse to the transport direction.

The tack piece can be offset in both directions transverse to the transport direction, thus requiring correction in both directions to achieve accurate alignment.

The invention also relates to a method for aligning a preferably flat material piece, in particular a flat area or an edge area of a textile sewn piece, in particular a correction station according to claim 1 or 2. A method for manual or automatic correction using a piece of material, said piece of material being conveyed at least near a plane area or an edge area in a conveying direction using a conveying device, preferably parallel to the edge area, At that time, it is preferably pressed against the supporting member of the conveying device by using the conveying means driven by the conveying device and is conveyed along the supporting member.

Methods and devices for aligning the edge regions of flexible material pieces, for example fibrous material pieces, are known in the prior art.

Under the concept of flexible material pieces, not only fibrous material pieces but also material pieces made of plastic, paper or similar materials can be used.

Devices are known in the prior art in which a fibrous material web is aligned 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 tack pieces are then realigned with the non-hemmed or unfolded edges of the tack pieces and transported by the appropriate transport equipment, the alignment being incorrect. The purpose is to allow subsequent heme formation and sewing of the edge area without appearance. The false appearance occurs when the outer edges of the sewn piece are not properly aligned. An aligning device and an aligning method in the prior art, wherein the pile edge provided on the tacking piece or the material piece is raised above the plane of the material piece in the aligning device and the aligning method. It is known that pile edges are used as alignment aids. Mechanical alignment means may be assisted by this pile edge and also align the pile edge with the corresponding subsequent equipment required for hemming and sewing, for example. However, in the absence of such pile edges, alignment is usually not possible or only possible with great difficulty.

For example, it may not be sufficient to align the front edge 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 piece of material because the piece of material is flexible and loses its alignment at the beginning when it is further conveyed by the appropriate equipment, which results in a high quality edge. It is impossible to form.

A particularly flexible material piece, when the material piece has not been previously separated from the material web, already provided with a longitudinal hem, and subsequently the material piece has been separated from the material web A great problem arises in changing the alignment status in order to ensure a high quality and precise alignment in the edge region in a flexible material piece to be provided with a corresponding lateral hem. However, such an alignment is a prerequisite for further processing of the corresponding sewn piece, etc., since mechanical hem formation and mechanical hem sewing may optionally have to be performed after the alignment. Only after these operations have been completed, the corresponding piece for provisional sewing is completed. An error in the preceding registration leads to the situation that a poor quality sewn piece is completed and thus does not meet the criteria.

One development is proposed to ensure, in a simple manner, the precise formation of the flat or edge areas of the material pieces in the form of textile sewn pieces.

In the conventional method way, the material pieces are first conveyed near the edge region in parallel with the edge region in the conveying direction using a conveying device. The transport device may, for example, consist of a circulating transport belt, which may continue to operate over further work stations of the manufacturing apparatus. When used in accordance with the regulations, the conveyor belt is pressed against a support member, for example a support plate, and is conveyed 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 taken for the solution by the present invention. That is, when the alignment of the material pieces is offset closer to the transport means from the target alignment of the material pieces, the area or edge area of the offset and aligned material pieces is Is moved away from the conveying means by a force, preferably a tensile force, acting towards or parallel to the plane stretched by the piece, corresponding to a direction transverse to the conveying direction, The offset alignment of the material pieces is thereby transferred to the target alignment.

The material pieces that are displaced in the conveying device in the direction of the conveying means are pulled in a direction transverse to the conveying direction, mainly by the force acting in the horizontal direction, and can be accurately aligned.

At this time, the following points are alternatively performed for the solution according to the present invention. That is, the edge region of the material piece is fixed in at least one second carrier that separates from the carrier and forms a free space with the carrier and is carried together in a synchronous manner to align the material pieces. An area of the fibrous piece stretched over the free space by means of a pressing force when is biased closer from the target alignment of the material piece towards the first conveying means And the textile piece is thereby moved away from the first conveying means by the amount corresponding to the direction of traversing the conveying direction and the direction transverse to the first conveying means, whereby the deviation of the material piece is caused. The registration with is transferred to the target registration.

As it is conveyed through the device, the edge region of the piece of material is fixed in the second conveying device. The second conveying device is preferably synchronized with the first conveying device, so that the material pieces are conveyed uniformly through the device. A free space is provided between the first transport device and the second transport device, and a 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 exerts a pressing force on the area in question, whereby the material piece is transferred to the first alignment until the first transfer. Moved only across the equipment.

At this time, the following points are alternatively performed for the solution according to the present invention. That is, the carrier device or a mechanical member disposed on the carrier device is provided with an alignment edge, or the support member forms an alignment edge, and the alignment edge is adjusted to an alignment status and the position of the material piece is adjusted. When the alignment is offset closer to the transport means from the target alignment of the material pieces, the area or edge area of the offset aligned material pieces is over the alignment edge. The alignment with the deviation of the piece of material that is pulled through and thereby moved away from the transport means by an amount corresponding to the direction transverse to the transport direction and corresponding to the direction transverse to the transport means is the target alignment. Will be moved to.

In accordance with the invention, alignment edges are provided at suitable locations on the machine frame, conveyor equipment, or other members of the overall apparatus and are used for the purpose of aligning the material pieces. The registration edge may be a stable edge. However, the alignment edges may also be provided in the form of rods, elastically tensioned wires or the like.

The support member itself may form the alignment edge. Each alignment edge is adjustable in a position suitable for target determination. As long as the piece of material is out of alignment with the target alignment, the piece of material can be moved over the alignment edge, thereby traversing the transport direction and the transport means. Alignment with the displacement of the material piece is thereby transferred to the target alignment.

The concept of transverse direction does not mean orthogonal, for example, it is sufficient if the tensile movements are directed obliquely, whereby one part of the tensile force component is directed horizontally and one part of the tensile force component The further part is oriented vertically. In any case, a sufficient degree of pulling force must be exerted on the material piece in order to move it 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 when the alignment of the material piece is offset closer to the transport means from the target alignment of the material piece, the offset. A region or edge region of the aligned and aligned piece of material extends over or in relation to the conveying direction that extends in relation to the conveying direction and is adjacent to the conveying means. Of the material piece is moved over the alignment edge of the recess, thereby traversing the conveying direction and away from the conveying means by a distance corresponding to the direction transverse to the conveying means, whereby the deviation of the material piece is caused. Positional registration is transferred to accurate target registration.

At least one of the projecting areas, preferably in both projecting areas, is provided with a recess or an outer edge extending parallel to the transport direction. The material pieces are, for example, above corresponding recesses or outer edges. The user can then check the alignment of the edge areas of the material piece and act on the material piece when the material piece alignment deviates from the exact target alignment of the material piece. Areas of material that are aligned with offsets of the material piece only if they extend out of the precise target alignment closer to the transport means by the edge areas of the material piece. Or the edge region passes over an outer edge extending parallel to the carrying direction, or over an outer edge of a recess extending parallel to the carrying direction and adjacent to the conveying means, Alignment with a displacement of the material piece, which is transverse to the transport direction and is pulled in a direction transverse to the transport means, whereby it is moved (pulled) away from the transport means by a corresponding amount Are transferred to accurate target alignment.

As soon as the target alignment has taken place, the pulling force is no longer exerted on the edge region of the material piece, and the material piece is further conveyed using only the conveying means. Such an arrangement and alignment is preferably carried out on the left and right sides adjacent to the conveying means, so that on the one hand the pulling force acting correspondingly on the edge region and on the other hand the tensioning correspondingly acting on the material piece. An equilibrium with the force is obtained, which leads to an accurate target alignment of the material pieces.

Preferably, the alignment edges are aligned parallel to the transport direction.

Such alignment is not necessary, but it is advantageous for implementing the method.

Alignment is possible even if the alignment is not exactly parallel, because the balance is obtained by the action of a corresponding force, which in the end ensures the desired alignment.

In addition, the pulling is preferably effected by the action of a force directed at least approximately perpendicular to the strip material.

This is advantageous for precise target alignment of the material pieces.

During the application of the force, in particular the pulling force, the means exerting said force or pulling force have an angle in the conveying direction with respect to said conveying direction, preferably parallel to the conveying direction of the conveying means It is very specially done to move one or the other, in the conveying direction, with respect to the strip-shaped material additionally in the conveying direction, preferably parallel to the conveying direction.

This results not only in that the alignment is carried out pointwise in a narrow area, but also over a relatively large area which extends substantially parallel to the transport direction, during the transport process. However, it is possible to perform the alignment in a discontinuous or continuous manner.

In this case, particularly preferably, the movement or movement component of the means in the conveying direction is adapted to the conveying speed of the conveying means, thereby avoiding folds of the band-shaped material.

When the material piece has a sensory or optically recognizable edge or outer edge, or markings, lines or steps extending parallel to the transport direction, the alignment of which deviates from the target alignment, It can also be carried out by means of which the technical means for precise target alignment of the material piece, as recognized by the means for carrying out or monitoring the method, are activated.

With regard to the device, the problems set out above are solved by the device according to claim 21.

The sewn piece is fed to the station automatically, preferably via a front device part or manually by an operator. The station has a carrier connected or built into it, so that the station itself is the carrier for receiving the sewn piece, or in some cases the carrier already starts in front of the station. What has been provided may be done so that the tack piece may be transported from or through the station to a transport device connected to the station. The tacking piece is transported into the processing station through the device using a transport device.

The post-correction of the sewn piece is performed by the inspection station and the correction station, so that the position of the sewn piece, which is displaced from the target position during the delivery or while being conveyed to pass through the device, is adjusted for the sewn piece. The piece is a processing station and has been modified before being fed to a processing station in which the tacking piece is processed. This ensures a particularly good quality of the intermediate or final product.

The inspection station may be provided in front of the correction station, whereby the inspection is carried out first and then the correction is carried out. Alternatively or additionally, the inspection station may be after the processing station, the inspection station inspecting the alignment of the machined tack piece and, if there is a deviation, the subsequent tack piece. Create modified specifications or modified values for.

The inspection station makes it possible to detect the marking layout in a contactless manner, preferably sensory detection is carried out using the human eye or corresponding equipment. Alignment of the piece for basting can be inspected at the outer edge because the edge can be recognized by a sensor, or at the edge of the pile for textile sewn pieces, but the detection must be based on markings such as patterns. Such an edge is not always necessary as it is also possible. At the inspection station, the previously detected marking layout is compared with the target marking layout and a correction value or specification is specified.

The correction value is supplied by a person at the time of the inspection, who performs a comparison between the marking layout and the target marking layout and identifies which correction value to set based on, for example, empirical values.

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

The correction of the alignment is then performed by the correction station, which carries out the accurate alignment of the tacking piece based on the correction value or the correction specification.

In the processing station, intermediate or finished products with excellent quality are produced. The processing station may be a fixture, in which the tack pieces are hemmed or sewn, for example. However, any other processing step may be performed.

Preferably, the inspection station has a detection device for sensory detecting the actual marking layout, a marking layout coupled with the detection device and detected, and a target marking layout, preferably stored in electronic storage. And processing equipment for comparing deviations, evaluating deviations, and optionally providing modified specifications.

The marking layout detected using the detection device is transmitted to the processing device, and the processing device performs a comparison with the target marking layout. The processing device is connected to the storage for that purpose, the storage having at least one target marking layout stored therein, the processing device accessing the data of the storage and comparing the target marking layout with the marking layout.

When the layout is deviated, the processing equipment calculates a modified specification and supplies it. The modified specifications are then transmitted to and displayed on the display panel. The modification specification may alternatively be provided as a corresponding control signal and may be communicated directly to the control unit of the modification station.

It is preferred that the detection device comprises a camera or a sensor device comprising at least one sensor.

The marking layout can be recognized in a non-contact manner by the sensor device or the camera.

It may be done that the sensor is preferably an optical sensor or a sensor performing distance measurement.

An optical sensor can be used to optically detect the marking layout. At this time, for example, the color or pattern can be detected. However, marking layouts of different pile height types on the surface of the sewn piece may be detectable. The marking layout of that type can also be detected optically. Alternatively, the type of marking layout can also be detected via distance measurement. To that end, a sensor is provided for performing distance measurement, which sensor detects the distance to the tip of the pile.

Preferably, the sensor is an optical sensor, and the light source is provided so as to face the sensor device or the camera, and the tacking piece is provided between the sensor device or the camera and the light source when being conveyed through the device. What is provided is being done.

A light source is provided facing the sensor device or the camera, and the light source illuminates the tacking piece in a transmissive manner, so that the sensor or the camera can better recognize the marking of the transmissible tacking piece.

Suitably, it may be provided that the processing equipment comprises a computer comprising a storage and at least one target marking layout stored in said storage for comparison with the actual marking layout.

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

Preferably, the correction station has a control unit, which is associated with an operating element for inputting correction values and optionally correction specifications, and is controlled by the control unit.

The correction value specified by the operator or the correction specification calculated by the processing device can be manually input to the operating element, which transmits a corresponding control signal to the control device. The correction station corrects the alignment in response to the input.

The modification can be effected, for example, by a suitable mechanical element, the control unit controlling the mechanical element in accordance with the modified value or the modified specification, so that the mechanical element exerts a corresponding mechanical action on the sewn piece. To fix the sewn piece in the correct position.

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

The display panel can be, for example, a monitor on which the modified specifications are displayed and can be read, so that the modified specifications can then be input to the operating element. As a result, the position of the tacking piece can be manually adjusted.

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 computer generated signal of the inspection station. What has been introduced to the unit may be done.

FIG. 7 shows the device in cross section in a second working position.

FIG. 1 is a method for accurately positioning and processing a piece 1 for sewn fabric, such as a textile product, which comprises the steps of the following method:
A step 3 of mechanically or manually feeding the (preliminary) aligned and/or positioned tacking piece 1 to the device 2 or a station 9 of the device 2;
The step 4 of inspecting the registration and/or the positioning of the basting piece, preferably marking the sewn piece on the surface of the sewn piece or in the weave of the sewn piece, Is detected sensorily and the actual marking layout is compared to the target marking layout,
5. A step 5 of identifying a modified value or modified specification, optionally providing a modified specification when the actual marking layout deviates from the target marking layout,
Step 6 of transmitting the correction value or specification to the correction station 12,
It is a step 7 of manually or mechanically correcting the alignment of the temporary sewing piece 1 using the correction station 12 according to the correction value or the correction specification, and the detected marking layout becomes the target marking layout. A step of matching and/or a processing station 13 for processing the piece 1 for sewn seams in the conveying direction 23, preferably a fixer, on which the processing steps are carried out in the fixer. Supplying step 8,
And optionally repeating individual method steps or repeating multiple method steps.

The tacking piece 1 can be manually removed by the operator, for example from a machine part in front or from a storage location. After that, before the supply 3 into the station 9, the operator manually positions or positions the temporary sewing piece 1, and the operator subsequently manually transfers the temporary sewing piece 1 into the station 9, or insert.

Alternatively, the automatic (preliminary) alignment or positioning of the sewn piece 1 may be performed, for example, in a preceding device part, in which the sewn piece 1 is (preliminarily) aligned, followed by a station 9. It is also possible in the part of the device that is automatically transferred or fed.

After the tacking piece 1 has been fed 3 into the station 9, the alignment and/or positioning of the tacking piece is inspected in the inspection station 11 and, if necessary, the correction 7 is performed in the correction station 12.

To that end, the sewn piece 1 is conveyed by means of a conveying device 10 past the device 2, and the method steps preferably elapse while conveying the sewn piece in a continuous or discontinuous manner. The inspection 4 and the modification 7 during the passage of the tacking piece 1 through the device 2 are particularly advantageous, since the tacking piece 1 may be displaced, especially during transport, before the tacking piece 1 is processed. This is because a correction 7 may be required prior to the feeding 8 to the processing station 13 and the execution of the processing steps in order to achieve the correct alignment. The continuous transport makes it possible, in particular, to carry out the process economically and to achieve speeds of 20 m/min.

Alternatively, the inspection 4 of the piece 1 for sewn-on seams is first performed after processing in the processing station 13. The course of this method is not shown in FIG. Deviation of the marking from the target marking layout, for example, when the stitches provided during processing are deviated from the target layout, the deviation is detected after the processing, and the correction specification or correction value is specified. The modified specifications or values are communicated to the modification station 12. The correction station 12 then carries out a corresponding correction for the subsequent tacking piece 1, whereby the subsequent tacking piece 1 is correctly aligned before the feed 8 to the working station 13.

The inspection 4 is performed in a non-contact manner, for example, by optically detecting the marking of the temporary sewing piece 1. The markings are preferably provided on the surface of the sewn piece, for example in the form of a pattern, or in the weaving of textiles, for example in the form of a weaving thread flow, or in the form of a weaving marking for meshes, seams, etc. and are detected optically. However, other detection elements that can detect the marking in a contactless manner may be provided. For example, markings of different pile height types can also be detected by distance measurement. To that end, a sensor may be provided for performing the distance measurement, which sensor detects the distance to the pile tip. If no deviation is found during inspection 4, no correction 7 is necessary and the method passes according to the dotted line Y, so that after inspection 4 a feed 8 to the processing station 13 takes place.

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

When the detection and comparison should be done by the eyes of the operator, the target marking layout is, for example, the transport base, on which the temporary sewing piece 1 is displayed or is formed by the transport base. It may have been done. 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 piece layout for provisional stitching from the target layout and specifies the correction value. The operator can specify the correction value on the basis of the empirical value and communicate it to the correction station, preferably via a manual input to the operating element 20 which is coupled to the correction station 12, whereby the correction value is dependent. Manual correction 7 is performed. The recognition by the optical device is preferably carried out by a sensor device 17 which comprises at least one sensor or by a camera, the piece 1 for sewn seams being conveyed through the sensor device 17 or the camera by means of a carrier device 10 and a sewn seam. The marking on the work piece 1 is detected optically.

The sensor device 17 or the camera preferably detects the actual path of the excursion and the direction of the excursion, which confirms the correct marking layout. In terms of direction, a deviation is detected on the left or right side in the direction transverse to the transport direction 23. The path is also accurately detected, i.e. how much deviation is present. The path may be identified in mm, for example. These images are then compared to the target marking layout, which allows accurate revision specifications to be created with corresponding dimensions.

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

If there is a deviation, the computer 19 creates a corresponding modified specification and supplies the modified specification to carry out the modification 7. The modification 7 can then be carried out automatically by transmitting the modified specification as a corresponding control signal to the modification station 12, which automatically carries out the modification 7 according to the modified specification. No human intervention is required, and a fully automatic correction 7 of the alignment of the piece 1 for temporary sewing is performed.

Alternatively, the calculated modified specifications may also be displayed on a display panel 22, such as a monitor, which allows an operator to read the specifications and enter them into the operating element 20 in communication with the modification station 12. it can. The modified specification is displayed, for example, in the form of a numerical value or the equivalent description, and may be read by an operator. The operating element 20 is preferably coupled to the modifying station via a control unit 21 of the modifying station 12, which controls the modifying station 12 in response to inputs to the operating element 20.
The operating element 20 and/or the display panel 22 are additionally an automatic correction 7, in which the control signals are directed directly to the correction station 12, even in the case of an automatic machine failure, for example. It may be provided for safety or for individual adjustment.

The correction station 12 then carries out a correction 7 according to the correction value or according to the correction specification, so that the marking layouts are matched.

The modification 7 can preferably be carried out by transmitting 6 the modified value or the modified specification to the control unit 21 of a suitable machine member, which control unit 21 responds the machine member to the modified specification or to the modified value. Controlled, the machine member carries out the correction 7 by exerting a corresponding mechanical action on the basting piece 1 to bring it into the correct position. The correction 7 is performed in both directions transverse to the transport direction 23, because the temporary sewing piece 1 may be displaced in both directions transverse to the transport direction 23, and the correction 7 is necessary in both directions. Only then can an accurate alignment be achieved. Such a marking layout and thus also a post-correction of the sewn piece 1 enables an accurate positioning of the sewn piece 1 in the device 2 and thus an accurate machining of the sewn piece 1 in the processing station 13. Therefore, a particularly expensive quality product is produced. Therefore, preferably, the inspection 4 and the correction 7 are carried out immediately before the machining step, whereby the tacking piece 1 is supplied to the machining section in a correctly aligned state.

In addition, the non-contact sensor-based inspection 4 also enables alignment of the rimless piece for basting, so that on the basis of only the handle, or in the case of the woven piece 1 for textiles, the fiber such as the flow of the weaving thread. Individual and accurate alignment and positioning can be done based only on the product markings. The tacking piece 1 may be processed in any manner, for example, a hem may be sewn or the tacking piece 1 may be folded. If the machining is followed by, for example, a further machining step in which the tacking piece 1 has to be accurately aligned, a new inspection 4 and a modification 7 may be carried out, The method steps can be repeated at any frequency.

FIG. 2 shows a schematic configuration of a device 2 for carrying out the method according to claim 1, the device 2 comprising:
A station 9 to which the tacking piece 1 is manually or mechanically (preliminarily) aligned and/or supplied in a positioned state;
A carrier device 10 connected to the station 9, optionally starting in front of the station 9, for carrying the tacking piece 1 past the device 2.
Whether the inspection station 11 detects the actual marking layout of the marking of the temporary sewing piece 1 in the inspection station, preferably by a sensor method, and can compare it with the target marking layout, and whether a correction value or specification is created. , An inspection station that can be created,
A correction station 12 for accurately aligning the temporary sewing piece 1 according to a correction value or specification
A processing station 13, preferably a fixer, in which the tacking piece 1 is supplied in a precisely aligned state and can be processed and is also machined.

The sewn piece 1 is fed to the station 9 automatically (preferably) aligned, preferably from a machine part in front or manually by an operator.

A carrier device 10 is connected to the station 9, the station 9 itself is the carrier device 10, and the provisional sewing piece 1 is supplied to the carrier device, or, as the case may be, the carrier device 10 is already in the station 9. Is provided so that it can be conveyed before or from the station 9 so that the piece 1 for sewn seams can be conveyed from the station 9 or through the station 9 to the conveying device 10 connected to the station. Good.

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

The sewn piece 1 is conveyed by the conveying device 10 through the device 2 past the inspection station 11 and the correction station 12 or through the inspection station and the correction station into the processing station 13. The inspection station 11 may alternatively be provided after the processing station 13, which is not shown in the figure. In this case, the inspection 4 is performed only after the first temporary sewing piece 1 is processed. As long as the deviation from the target layout is detected, the correction specification or correction value is transmitted to the correction station 12 provided in front of the processing station 13, so that the alignment correction is performed before the processing. Post-correction of the sewn piece 1 is carried out by the inspection station 11 and the correction station 12, whereby alignment of the sewn piece 1 deviates from the target position during delivery or during transport through the device 2. Is corrected before the provisional sewing piece is the processing station 13 and the provisional sewing piece 1 is supplied to the processing station where the provisional sewing piece 1 is processed into an intermediate product or a final product in the processing station 13. This ensures a particularly good quality of the intermediate or final product.

FIG. 3 shows a first variant of the device 2. The inspection station 11 makes it possible to detect the marking layout in a contactless manner. To that end, the inspection station 11 has a detection device 14, which is a sensor device 17 comprising a camera or at least one optical sensor. The layout of the tack-fitting piece 1 can thereby be detected and the edges are optically recognizable, so that they are outer edges or pile edges which can be aligned on the basis of said outer edges or pile edges. The outer edges or pile edges are not necessary, as the pile edges can be detected but optical detection based on any pattern or such marking is also possible. Alternatively, the marking can also be detected by distance measurement. To that end, a sensor is provided for performing distance measurement, which sensor detects the distance to the tip of the pile. After that, in the processing equipment 15 of the inspection station 11, which is combined with the detection equipment 14, the detected marking layout is compared with the target marking layout and the correction specification 5 is performed. This is done by the appropriate technical means for processing the data, in the embodiment a computer 19 connected to the storage 16 is used. The marking layout detected using the camera or the sensor device 17 is transmitted to the processing device 15 or the computer 19 included in the processing device. The computer 19 may then perform a comparison of the marking layouts with the target marking layouts stored in the storage 16, which may have different target marking layouts stored, or may later be replaced by a new production line for a new production line. You can program different target marking layouts. These are then selected according to the production line and made available for comparison with the corresponding marking layout detected.

A modified specification is calculated by the computer 19 when the marking layout deviates from the target marking layout. The modified specification is transmitted to the receiving section of the modification station 12 via appropriate technical means, and the modification station performs the modification 7 according to the specification.
The correction specifications are transmitted to the control unit 21 of the correction station 12 in the form of control signals of the computer 19, for example.

In this case, the inspection station 11 is coupled in direct communication with the correction station 12. Thereby, the correct correction 7 is automatically performed according to the correction specification without human assistance.

The modification 7 can be carried out, for example, by means of a suitable machine element, the control unit 21 controlling the machine element in accordance with the modification specification, which machine element exerts a corresponding mechanical action on the tacking piece 1. The correction 7 is carried out to adjust the provisional sewing piece 1 to the correct position.
If there is no excursion, then Correction 7 is not performed.

Subsequently, the piece 1 for provisional sewing is supplied to the processing station 13. The processing station 13 may be a fixing device in which the temporary sewing piece 1 is, for example, hemmed, glued or sewn. However, it may be a device for folding the temporary sewing piece 1 or a device for performing any other processing step.

At the processing station 13, intermediate or finished products with excellent quality are produced.

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 the human eye in the inspection station 11.

The comparison is, for example, that the target marking layout referred to for comparison is the transport base and is displayed on or formed by the transport base on which the temporary sewing piece 1 is transported. Done by. The operator recognizes the deviation of the piece layout for provisional stitching from the target layout and specifies the correction value. The operator can specify the correction value on the basis of the empirical value and transmit it to the correction station via a manual input to the operating element 20 coupled to the correction station 12, whereby a manual operation depending on the correction value. Expression modification 7 is implemented. The correction station 12 has an operating element 20 for that purpose.

The third variant is shown in FIG. The detection and comparison are carried out in the same way as in the first embodiment, i.e. by means of the detection device 14 (eg sensor) and the processing device 15 in the inspection station 11, the computer 19 of the processing device 15 being coupled to the display panel 22. At the same time, the calculated modified specifications are transmitted to the display panel, and the modified specifications are displayed on the display panel 22. The displayed modification specification is read and manually entered into the operating element 20 associated with the modification station 12. The correction station 12 has a control unit 21 connected to the operating element 20 and is controlled by the control unit in response to the input.

The fourth variant is shown in FIG. In this figure, the detection is performed using the sensor of the sensor device 17, and the light source 18 is provided so as to face the sensor. When the provisional stitching piece 1 is conveyed through the device 2, it is provided between the sensor device 17 and the light source 18, and is transmitted and illuminated by the light source 18, whereby the sensor is, for example, a textile article provisional stitching piece 1. Better recognition of markings in the weaving of fibers.

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

The further device shown in FIGS. 7 to 11 serves to align the edge region 101 of the preferably flexible material piece 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 fibrous web and having a quasi-rectangular basic shape. The device consists essentially of a conveying device 103 having an implied mechanical frame 104 for a material piece 102, comprising a driven conveying means 105, for example a conveying belt, and a support member 106 for the conveying means 105. Become. In the embodiment, the support member 106 is formed as a plate. The material piece 102 is placed on the plate. The conveyor means 105 in the form of a belt drive is mounted above the material piece 102, whereby the material piece is pressed against the support member 106. The support member 106 is preferably a flat, smooth plate. The transport means 105, preferably formed as a transport belt of the belt drive, is associated with a spring-biased support block 107 on the upper side, which supports the transport means 105 towards the support member 106 in an elastic manner. Press in a prestressed state. These support blocks 107 are held by the components of the machine frame 104. The visible part of the machine frame 104 is formed as a metal sheet bent into an L-shape, one leg of the metal sheet being oriented parallel to the extension of the support member 106 and the other. The legs are oriented perpendicular to the extension of the support member.

The area of the material piece, which is near the edge area 101 of the material piece 102, is either clamped or clamped between the support member 106 and the conveying means 105, It is conveyed parallel to the edge region 101 in the conveying direction 108 by 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-corrugation, whereby the edge region is It is not aligned exactly parallel to the direction, but has a different shape with respect to the carrying direction and extends a different distance from the conveying means 105.

The support members 106 project from the transport means 105 on both sides in a direction transverse to the transport direction. The protruding area is described by 109 or 110. In the exemplary embodiment, in both projecting areas 109, 110 there are provided recesses 111, 112 with outer edges 113, 114 oriented parallel to the transport direction 108, said outer edges respectively being conveying means 105. Is adjacent to. Alternatively, it is also envisaged that one outer edge 115, 116 of each of the projecting areas 109, 110 of the support member 106 is used depending on the purpose, which outer edge 115, 116 is also oriented parallel to the conveying direction 108. ing. Furthermore, on the outer edge 113 or 114, and possibly also on the outer edge 115 or 116, a respective control means 117, 118 is indirectly fixed to the machine frame 104, said control means being in the basic position. , 9 and 10, the working member of the control means in the basic position is outside the plane stretched by the gap between the support member 106 and the transport means 105, In the embodiment, it is possible to adjust and move from a basic position on the plane to the working position, which working position is shown in FIGS. 8 and 11, in which the control means presses the plane, That is, the member is positioned pseudo below the projecting region 109 or 110.

The control means 117 or 118, during the adjustment movement in the direction transverse to the conveying direction 108 and in the direction transverse to the plane mentioned above, in particular as shown in FIGS. It is also moved through 115, 116 with a relatively narrow distance to the outer edge and with the area of the material piece 102 next to the conveying means 105.

Therefore, the edge area 101 or the edge area 101a located beyond the conveying means 105 can be aligned by using the control means 117 or 118 depending on the required alignment. 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. 11, a lateral force is applied to the corresponding edge region 101 or region 101a of the material piece 102. And the lateral force causes the piece of material 102 in the area that engages the control means 117, 118 to move away from the transport device 103, thereby locating the layout of the edge area 101 exactly as desired. To match.

In order to ensure that the material piece 102, in particular the edge of the material piece 102, is entrained in the adjustment movement of the control means 117, 118 from the basic position to the working position, in the course of the control means 117, 118, on the support member 106, Moreover, a swivel-movable support 119 is held on the outer edge of the recess 111, 112 in the region of the front in the transport direction, and the control means 117 is used during the adjustment movement to the working position. , 118 pushes against the support, pushing it down, eg transversely to the transport direction, as can be seen in FIG. The edge area 101 of the material piece 102 provided therebetween is fixed between the control means 117, 118 and the support 119, so that the edge area 101 is revealed as shown in FIG. Is moved down across the carrying direction 108 as desired. The length of the stroke for adjusting and moving the control means 117, 118 from the basic position to the working position for the purpose of accurately aligning the edge regions 101, 101a of the material piece 102 can be adjusted, for example by an operator, As a result, a relatively large adjustment movement stroke or a relatively small adjustment movement stroke is executed according to the deviation of the outer edges of the edge regions 101 and 101a from the target position.

The support 119 is in particular elastically movably fixed to the support member 106, in particular to the outer edges of the recesses 111, 112 which are forward in the transport direction 108.

As a result, when the control means 117, 118 are adjusted and moved, the support portion 119 is automatically moved in accordance with the adjusted movement stroke.

It is not shown in the figure that the control means 117, 118 are formed as a cleat, roller or stamp at the free end of the control means facing the piece of material 102. This is a possible configuration. However, at this time, it is assumed that the actuation of the control means, ie the adjustment movement of the control means from the basic position to the working position, needs to be carried out intermittently, whereby during the transport of the material piece 102 in the transport direction 108, The edge regions 101, 101a, which respectively underlie the control means, can be correspondingly pulled by the control means, thereby achieving a precise alignment.

At this time, it is preferable that the control means is the belt driving unit 120 or 121 including the driven roller 122 and the roller 123 that freely rotates, and the belt of the belt driving unit 120 or 121 is arranged around the roller. Orbited and moved.

As a drive unit for the driven rollers 122 of the control means 117 and 118, a motor type rotary drive unit 124 is held and fixed to a frame member, for example, a member of the machine frame 104, and the motor type rotary drive unit is coupled. The means 125, in the embodiment shown, is connected to the drive shaft 126 via a drive belt. The drive shaft 126 additionally has for this purpose a roller 127 fixedly connected to the shaft. The drive shaft 126 is supported and guided in a mounting block 128, which is also frame-fixed to a member of the machine frame 104. The drive shaft 126 is fixedly connected to the driven rollers 122 of both control means 117, 118, whereby the belt drives 120, 121 are moved via the rotation of the drive shaft 126. The orbital direction of the coupling means 125 (of the drive belt) is indicated at 129. In addition, the control means 117, 118 can be adjusted and moved by means of an actuator 130 fixed to the machine frame 104. The actuator 130 therefore comprises, for example, an electric motor drive 131, which can be alternately operated only in the right and left directions. Through the output shaft 132, the disk-shaped driver 133 is rotated clockwise or counterclockwise in a limited manner around the axis formed by the output shaft 132. In this driver, the components 138, 139 of the control means 117, 118 are pivotable about the drive shaft 126 via the connecting rods 134, 135 and the connecting rods 136, 137. By rotating the driver 133 in one direction (eg clockwise) using the drive 131, the entire element having the belt drive is swiveled from the basic position to the operating position, whereby the control means 117 is moved to the operating position. The roller 123, which is adjusted and freely rotated in the working position, is adjusted and moved downward as is apparent from FIG. 11, for example. This movement of the driver 133 raises the control means 118 on the other side. If the direction of rotation of the driver 133 is opposite, the control means 117 is raised while the control means 118 is likewise lowered and the freely rotating rollers 123 in the control means are moved downwards. With this arrangement, both control means 117, 118 cannot act on the piece of material at the same time, only the respectively selected control means 117, 118 act on the piece of material, as should be determined by the user. It is guaranteed to be possible.

In order to guide the edge regions 101, 101a of the material piece 102 in the conveying direction 108 completely even after passing through the recesses 111, 112, one guide each is provided following the recesses 111, 112. A part 140 is provided, the guide part being transferred steplessly in the conveying direction into the subsequent region of the projecting region 109 or 110 of the support member 106.

In the embodiment, the control means 117 and 118 are formed by actuators that circulate in the same direction with respect to the transport direction 108, in particular, belt drive units 120 and 121, and at least the corresponding actuators of the circling actuators have basic positions. From the working position to the working position and continuously during the working position. This allows the edge regions 101, 101a to be machined in a manner compatible with the conveying direction and the conveying speed of the material piece 102, thereby achieving alignment of the edge regions 101 or 101a in the correct manner.

The positions of the edge regions 101 and 101a deviating from the target position can be visually detected by the operator, and thereby the operator can operate the corresponding device according to the regulation. However, the edge areas 101, 101a or the outer edges of the edge areas are detected with respect to the position of the edge areas by means of a suitable detection device and the corresponding mechanical control causes the control means 117, 118 to operate in accordance with the regulation. It is also possible and possible.

The apparatus shown in FIGS. 7 to 11 is suitable and defined for enabling a method for aligning the edge regions 101, 101a of a material piece 102, in particular a textile sewn piece. To that end, the material piece 102 is conveyed near the edge areas 101, 101a in parallel with the edge areas in the conveying direction 108 by means of a conveying device, for example conveying means 105. At this time, the material piece is pressed against the supporting member 106 of the conveying device 103 by the conveying means 105 driven by the conveying device 103, and is conveyed in the conveying direction along the supporting member 106. The manner of the apparatus and method described may of course be provided on both sides of the material piece 102, so that the devices corresponding to both edge areas are arranged and attached. The material pieces may hang freely between the device parts provided on both sides, for example by forming a loop.

The support member 106 projects from the conveying means 105 on both sides in a direction transverse to the conveying direction 108, as required. Recesses 111, 112 are provided in both projecting areas 109, 110, which recesses underlie corresponding areas of the material piece 102. The alignment of the material piece 102 deviates from the exact target alignment of the material piece 102, i.e. the edge region 101 or 101a of the material piece extends closer to the transport means 105. Then, the regions or edge regions 101, 101a of the material pieces 102 which are offset and aligned are passed over or over the edges of the support member 106 which extend parallel to the conveying direction 108. In a direction that extends parallel to the direction 108 and is pulled over the outer edges of the recesses 111, 112 adjacent to the transport means 105, thereby traversing the transport direction 108 and transverse to the transport means 105. , Is moved or pulled away from the transport means 105 by a corresponding amount, whereby the offset registration of the material piece 102 is corrected and transferred to an exact target registration.

The tension acting on the strip material in the region of the corresponding control means 117, 118 is brought about by the action of a vertical force, whereby good force transmission and alignment is achieved. During the application of the tensile force, the means for applying the tensile force preferably interlocks parallel to the conveying direction 108 of the conveying means 105, or adds a movement component parallel to the conveying direction 108 to the strip material. Resulting in avoiding distortion of the piece of material. The movement or movement component of the means parallel to the conveying direction 108 is adapted to the speed of the conveying means 105, thereby achieving a smooth action on the strip material and in particular avoiding folds. To facilitate alignment, the material piece 102 has markings, lines or steps that extend parallel to the visually recognizable edges or edges or the transport direction 108, thereby allowing for alignment from the target alignment. The offset registration is recognized by the means for carrying out or monitoring the registration method, which triggers the technical means for precise target registration of the material pieces. The means for monitoring may be the eyes of the operator, or may also be electrical, electronic or other detection means.

With the described device and the described method, it is possible in a remarkable manner to align the edge regions of the flexible material piece in a defined manner, whereby the subsequent formation of hem and Work processes such as sewing hem can be mechanically connected. The alignment takes place especially during the normal operating mode of the carrier device 103, so that an accurate alignment can be achieved during the normal transport process.
