Description

The present invention relates to a method and an apparatus for accurately positioning and processing a piece for tacking, such as a textile product.

Methods and corresponding devices in the prior art, such as textile webs or textiles such as textile tack pieces, are manually or automatically (preliminarily) aligned and processed, for example, in a correspondingly aligned state. It is known that it is supplied to the step or to the transport equipment of the device. The transport equipment transports the textiles to various processing stations through the equipment.

Using such methods and corresponding devices, not only fibrous tack pieces but also tack pieces made of any material that can be processed in the same manner as the fibrous material are handled. This includes, for example, a tack piece made of paper or plastic.

For example, automatic (preliminary) alignment of fiber webs is known, where the fiber webs are precisely aligned prior to processing, eg, cutting the web into tack pieces.

Alignment of the fiber web is performed mechanically, for example, by mechanically examining the outer or pile edges of the textile relative to a segmented alignment rail. At this time, the position adjustment rail sets accurate alignment.

To be able to perform such mechanical alignment, the fiber web must have an edge that can be detected by the alignment rails, which can pull the web to the desired position. .. This has the disadvantage that this type of alignment cannot be performed without an outer or pile edge, for example, depending on the flow of the handle or thread or mesh. In addition, textiles must be endless, as is the case with textile webs. This type of alignment is not possible with textile tack pieces.

After the fiber web is accurately aligned, the tack piece 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 delivered automatically or manually to a portion of the device that further processes the basting piece. ..

When automatically delivered, the tack piece is a station via the corresponding delivery means and / or transport means, for example further processing can be performed at the station, or the tack piece is further transported from the station. Handed over to the station to be. At this time, the deviation from the accurate alignment generated when cutting the (preliminary) aligned fiber product is inherited. Even during the delivery process to the station, the tack piece may slip in the device, so that the tack piece is no longer in the accurately aligned state. This makes it impossible to perform accurate further processing of the tack piece, resulting in poor quality products.

During manual delivery, the operator receives the tack piece from the fronted machining station or storage location and supplies it to the station in a manually (spare) aligned state, but in a manual position. Alignment and positioning can be performed by the operator aligning the tacking piece by eye or by using a mechanical assisting means and providing it in the apparatus. Inexperienced unskilled workers, and even when skilled workers are inadvertent, can cause inaccuracies in alignment and positioning, making it impossible to process textiles in an accurately aligned state. There are disadvantages. This inaccuracy leads to poor quality of the textile intermediates or final products produced in the process and thus does not meet the standards.

Even if the tack piece is delivered manually or automatically in a precisely (preliminary) aligned state, it may deviate from the correct alignment when transporting the tack piece to the machining station. There is. For example, a belt drive is used as the transport means, which transports the tack piece so that it passes through the device on the transport plate, but it is particularly thick and / or flexible. In the case of textiles, the tacking piece may slip in the transport device, resulting in a situation where accurate alignment is not ensured during further processing.

The subject of the present invention is a method and an apparatus, in which the tacking pieces supplied to the machining station are accurately aligned in the method and using the apparatus, which is particularly valuable in terms of quality. By creating methods and equipment that ensure that the product can be manufactured and at the same time individual alignment of tack pieces, such as textiles without outer and / or pile edges, is possible. be.

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

The tack piece can be manually removed by the operator, for example from the pre-installed device portion or from the storage location. A manual (preliminary) alignment or positioning of the tack piece is then performed in the device, especially prior to feeding to the device station, and the operator subsequently manually feeds the tack piece to the device or station. ..

Alternatively, automatic (spare) alignment or positioning of the tack piece is, for example, a preceding device portion in which the tack piece is (spare) aligned or positioned, followed by the device or It is possible in the equipment part that is automatically supplied to the station. The station may be, for example, a transport station, which transports the tack piece to pass through the device or fulfills any other task.

After the tack piece is supplied, the alignment and / or positioning of the tack piece is inspected and corrections are made if necessary. The inspection is preferably carried out by non-contact detection, for example by sensor marking of the tack piece. The markings are preferably provided on the surface of the tack piece, for example, in the form of a pattern, or in the weaving of textiles, for example, in the flow of weaving threads, or in the form of woven markings such as meshes, seams and the like. The markings may also be formed in the form of a pattern formed, for example by different pile heights, due to differences in weaving. The marking is preferably detected by a sensor.

Sensor-based detection can be performed with the human eye or through a suitable device. The detected marking layout is compared with a given target marking layout. This is also selectively performed by humans or by suitable processing equipment, such as data processing equipment.

If the detection and comparison is done by the operator's eyes, the target marking layout is, for example, a transfer base, where the tack piece is displayed on or formed by the transfer base to be conveyed on it. You may be. The operator recognizes the deviation of the tack piece layout from the target layout and identifies the correction value. The operator can identify the modification value based on the empirical value and transmit it to the modification station, for example, through manual input to the operation element coupled to the modification station, whereby the manual expression according to the modification value can be obtained. Corrections will be implemented.

If the deviation is recognized by the equipment, the recognized marking layout is transmitted, for example, to a processing station, which then performs a comparison with the target marking layout, which is preferably stored in the processing equipment. It is remembered and available for comparison with the actual marking layout. If the processing equipment has a deviation, the correction specification is calculated, and the correction specification is directly transmitted to a suitable receiver of the correction station, whereby automatic alignment correction by the correction station is performed.

An alternative calculated modification specification may also be displayed on a display panel such as a monitor, which allows the operator to read the specification and manually enter it into the operating element coupled to the modification station. can.

The correction device then performs the correction according to the correction value or the correction specification, whereby the marking layout is at least approximately matched. The modification can be performed, for example, by transmitting the modification value or modification specification to a control unit of a suitable machine member, the control unit controls the machine member, and the machine member is a machine corresponding to the tack piece. The correction is performed by exerting a target action, and the tacking piece is aligned with the correct position.

Such post-correction of the marking layout and along with the tack piece allows for accurate positioning of the textile in the appliance, thereby allowing accurate machining of the textile in the processing station, especially expensive good quality. Goods are produced.

In addition, preferably non-contact inspection also allows alignment of edgeless tack pieces, thereby providing individual and accurate alignment and positioning based solely on textile markings such as patterns or thread flow. It can be carried out.

After machining, for example, when further machining steps are followed, for example, further machining steps in which the tack piece needs to be accurately aligned in the further machining step, new inspections and corrections may be made, individually. Or multiple method steps may be repeated.

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

The tack piece may be manually removed by the operator, eg, from a fronted device portion, or from a storage location and manually supplied to the device. Manual (preliminary) alignment or positioning of the tack piece is performed prior to supply of the device, especially the device to the station.

Alternatively, the tack piece can be automatically (preliminarily) aligned or positioned and subsequently automatically supplied to the device or station. The station may be, for example, a transport station, which transports the tack piece to pass through the device or fulfills any other task.

After the first tack piece is supplied, the first tack piece is machined in the machining station. Subsequently, the alignment and positioning of the first tack piece is inspected. As long as the deviation from the target marking layout is confirmed at the time of inspection, the correction value or the correction specification is specified, and the correction value or the correction specification is transmitted to the correction station provided in front of the machining station. Subsequent tack pieces that are then conveyed through the device are aligned according to the modification value or modification specification prior to supply to the machining station. As a result, the subsequent tacking piece is accurately aligned with the machining step, and it is possible to manufacture a product having high quality in terms of quality.

The inspection is preferably carried out by non-contact detection, for example by sensor marking of the tack piece. The markings are preferably provided on the surface of the tack piece, for example, in the form of a pattern, or in the weaving of textiles, for example, in the flow of weaving threads, or in the form of woven markings such as meshes, seams and the like. The markings may also be formed in the form of a pattern formed, for example by different pile heights, due to differences in weaving. The marking is preferably detected by a sensor.

Sensor-based detection can be performed with the human eye or through a suitable device. The detected marking layout is compared with a given target marking layout. This is also selectively performed by humans 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 tack piece layout from the target layout and identifies the correction value. The operator can identify the modification value based on the empirical value and transmit it to the modification station, for example, through manual input to the operation element coupled to the modification station, whereby the manual expression according to the modification value can be obtained. Corrections will be implemented.

Alternatively, the detection and comparison can be recognized by the instrument, the detected marking layout is transmitted, for example, to a machining station, which then performs a comparison with the target marking layout. The target marking layout is preferably stored in the storage of the processing equipment and can be used for comparison with the actual marking layout. If the processing equipment has a deviation, the correction specification is calculated and the correction specification is directly transmitted to the suitable receiver of the correction station, whereby the correction station automatically aligns the subsequent tack piece. You can make corrections.

An alternative calculated modification specification may also be displayed on a display panel such as a monitor, which allows the operator to read the specification and manually enter it into the operating element coupled to the modification station. can.

The correction device makes corrections according to the correction value or the correction specifications, whereby the marking layout is at least approximately matched. The modification can be performed, for example, by transmitting the modification value or modification specification to a control unit of a suitable machine member, the control unit controls the machine member, and the machine member is a machine corresponding to the tack piece. The correction is performed by exerting a target action, and the tacking piece is aligned with the correct position.

Such post-correction of the marking layout and along with the subsequent tack piece allows for accurate positioning of the textile in the appliance, thereby allowing accurate machining of the subsequent textile in the machining station. Especially expensive high quality products are produced.

In addition, preferably non-contact inspection also allows alignment of edgeless tack pieces, thereby providing individual and accurate alignment and positioning based solely on textile markings such as patterns or thread flow. It can be carried out.

After processing, new inspections and modifications may be made and the steps of individual or multiple methods may be repeated.

Preferably the steps of the method are performed during continuous or discontinuous transport of the tack piece.

The tacking piece is conveyed by the conveying device so as to pass through the device. During transport, the tack piece can shift in the appliance, which is advantageous for correction during transport, thereby aligning the tack piece again and accurately in front of further machining stations. The steps of the method can preferably be carried out while the tack piece is continuously conveyed through the apparatus, whereby the method can be carried out economically. At this time, a very large speed of 20 m per minute can be achieved. However, if necessary, discontinuous transport can also be performed.

Preferably the modification is carried out just before the supply for machining and the performing of the machining step.

This ensures that the tack piece is accurately aligned and fed to the machining station and machined within the machining station to produce a product of particularly good quality.

Preferably, a sensor device or camera with at least one sensor detects the marking on the tack piece, the sensor device or camera communicates with the computer, and the computer stores the actually detected marking layout in the computer's storage. Compared to the target marking layout, if there is a deviation, a correction specification for automatic or manual correction is provided.

The tack piece is transported through the sensor device or camera using transport means, and at least one sensor or camera detects the pattern or thread flow of the tack piece. Alternatively, the sensor device or camera can be transported so as to pass through the tack piece. The sensor device or 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 contains 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 modification and supplies the modification to implement the modification. The correction can be performed automatically by transmitting the correction specification as a corresponding control signal to the correction station.

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

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

This creates an accurate marking layout. With respect to the direction, for example, the deviation is detected on the left side or the right side in the direction traversing the transport direction. The path is also detected accurately, i.e., how much deviation there is. The route may be confirmed, for example, in mm. These imagings are compared to the target marking layout, which allows accurate correction specifications to be created with the corresponding dimensions.

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

This allows deviations from the target marking layout to be detected, for example, based on pile height or other uplift transitions on the surface of the tack piece.

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

The operator can input the specified correction value into the operation element to correct the alignment.

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

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

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

The modified specifications are displayed on the display panel, for example, in numerical values or the equivalent type, and can be read on the display panel. This value is optionally used for manual correction by the operator entering the value into an operating element that communicates with the correction station. Alternatively or additionally, the deviation may be displayed, and the correction value can be specified from the deviation.

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

This eliminates the need for human intervention and allows for fully automatic correction of the alignment of the tack piece. Operating elements and / or display panels may be additionally provided for safety in the event of an automated machine failure or for individual adjustment.

Preferably, the modification is made in both directions so that the modification traverses the transport direction.

The tack piece can be misaligned in both directions across the transport direction, which requires correction in both directions to achieve accurate alignment.

The present invention is also a method for aligning a plane region or an edge region of a material piece, particularly a fibrous tack piece, preferably having flexibility, particularly the modification station according to claim 1 or 2. With respect to the method for manual or automatic modification using, the material piece is transported at least near a planar region or an edge region and preferably parallel to the edge region in the transport direction using a transport device. At that time, it is preferably pressed against the support member of the transfer device by using the transfer means driven by the transfer device, and is conveyed along the support member.

In the prior art, methods and devices for aligning edge regions of flexible material pieces, such as fiber material pieces, are known.

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

In the prior art, there are known devices in which the fibrous material web is aligned and hemed at the longitudinal edge of the fibrous material web. After hemming, these webs are aligned and split into substantially rectangular basting pieces. These tack pieces were then realigned using the unhemed or unfolded edges of the tack piece and transported by the appropriate transport equipment, which was misaligned. It is done for the purpose of allowing subsequent hem formation and sewing of the edge area without the appearance. The incorrect appearance occurs when the outer edges of the tack piece are not accurately aligned. In the prior art, it is an alignment device and an alignment method, and in the alignment device and the alignment method, a pile edge provided on the tacking piece or the material piece is raised on a flat surface of the material piece. It is known that the pile edge is used as an alignment aid. Mechanical alignment means can be assisted by this pile edge, for example also aligning the pile edge to the corresponding subsequent equipment required for hem formation and sewing. However, in the absence of such pile edges, alignment is usually not possible or only possible with great difficulty.

For example, it is not sufficient to align the foremost end of the edge region of the material piece and then transport the material piece by a suitable device, because the alignment position formed at the start of the material piece. Does not continue across the material pieces, because the material pieces are flexible and lose their alignment at the start when further transported by the appropriate equipment, thereby resulting in high quality edges. Formation is impossible.

Especially when the material piece is flexible and has previously been provided with a longitudinal hem when the material piece has not yet been separated from the material web, and subsequently when the material piece has been separated from the material web. Changing the alignment status to ensure high quality and accurate alignment in the edge region in flexible material pieces that should be provided with a corresponding lateral hem poses great problems. However, such alignment is a prerequisite for further machining of the corresponding tack piece, etc., as mechanical hem formation and mechanical hem sewing may have to be performed after the alignment, as the case may be. Only after these operations are completed will the corresponding tacking piece be completed. Mistakes in the preceding alignment lead to the completion of poor quality tacking pieces and therefore non-compliance with the criteria.

One evolutionary configuration is proposed to ensure the precise formation of the planar or edge regions of the material piece in the form of a fibrous tack piece in a simple manner.

In the conventional method, the material piece is first transported near the edge region and parallel to the edge region in the transport direction using a transport device. The transport device may consist of, for example, an orbiting transport belt, which may continue to operate over additional work stations of the manufacturing apparatus. When the transport belt is used according to the regulations, it 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 (convey 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 the material piece is displaced closer to the transport means from the target alignment of the material piece, the region or edge region of the displaced and aligned material piece is the material. A force acting parallel to or parallel to the plane stretched by the piece, preferably a tensile force, causes it to move away from the transport means by the amount corresponding to the direction across the transport direction. As a result, the alignment with the deviation of the material piece is shifted to the target alignment.

Material pieces that are displaced in the direction of the transport means in the transport device are pulled in a direction crossing the transport direction by a force acting mainly in the horizontal direction, and can be accurately aligned.

At this time, in order to solve the problem according to the present invention, the following points are substituted. That is, the edge region of the material piece is fixed in at least one second transport device that is separated from the transport device and forms a free space with the transport device, is transported together in a synchronous manner, and aligns the material pieces. Area of the textile piece where at least one actuator is stretched over the free space using pressing force when is deviated closer to the first transport means from the target alignment of the material piece. The textile piece is thereby moved away from the first transport means by the amount corresponding to the direction traversing the first transport means, thereby causing the material piece to deviate. Alignment with is shifted to target alignment.

When transported through the device, the edge area of the material piece is secured within the second transport device. The second transfer device is preferably synchronized with the first transfer device so that the material pieces are uniformly transferred 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 acts on the area using the pressing force, whereby the material piece is first transported until it is transferred to the target alignment. Moved only in the direction across the device.

At this time, in order to solve the problem according to the present invention, the following points are substituted. That is, the transfer device or the mechanical member disposed in the transfer device is provided with an alignment edge, or the support member forms an alignment edge, the alignment edge is adjusted to the alignment status, and the position of the material piece. When the alignment is displaced closer to the transport means from the target alignment of the material piece, the area or edge area of the displaced and aligned material piece is over the alignment edge. Alignment with deviation of the material piece is targeted alignment by being pulled through and thereby traversing the transport direction and moving away from the transport means by the amount corresponding to the direction across the transport means. Will be migrated to.

According to the present invention, a positioning edge is provided at a suitable position on a mechanical frame, a transport device, or other member of the entire device, and is used for the purpose of aligning a material piece. The alignment edge may be a stable edge. However, the alignment edge may be provided in the form of a rod, an elastically stretched wire, or the like.

The support member itself may form an alignment edge. Each alignment edge is adjustable in a suitable position for target determination. As long as the material piece is aligned offset from the target alignment, the material piece can be moved over the alignment edge, thereby traversing the transport direction as well as across the transport means. And thereby the alignment with the deviation of the material piece is transferred to the target alignment.

The concept of transverse direction does not mean orthogonal, for example, it is sufficient if the tensile movement is directed diagonally so that one part of the tensile force component is directed horizontally and one of the tensile force components. The additional part is oriented vertically. In any case, a sufficient amount of tensile force must be exerted on the material piece in order to move the material piece to the desired degree.

At this time, the following points are preferably performed. That is, when the support member has at least one recess or alignment edge and the alignment of the material piece is displaced closer to the transport means from the target alignment of the material piece, the deviation The area or edge area of the material piece thus aligned extends over the alignment edge that extends in relation to the transport direction, or extends in relation to the transport direction and is adjacent to the transport means. It is moved over the alignment edge of the recess, thereby traversing the transport direction and moving away from the transport means by the amount corresponding to the direction across the transport means, thereby biasing the material piece. Positioned alignment is transferred to accurate target alignment.

In at least one of the protruding regions, preferably within both protruding regions, a recess or an outer edge extending parallel to the transport direction is provided. The material piece is, for example, on the corresponding recess or outer edge. At this time, the user can confirm the alignment of the edge region of the material piece, and acts on the material piece when the alignment of the material piece is deviated from the accurate target alignment of the material piece. A region aligned with a deviation of the material piece only if the material piece is displaced and extended closer to the delivery means by the edge region of the material piece from accurate target alignment. Alternatively, the edge region may pass over an outer edge that extends parallel to the transport direction, or over the outer edge of a recess that extends parallel to the transport direction and is adjacent to the transport means. Alignment with deviation of the material piece in a direction that traverses the transport direction and is pulled in a direction that traverses the transport means, thereby being moved (pulled) away from the transport by the corresponding amount. Is transitioned to accurate target alignment.

As soon as the target alignment is performed, the action of the tensile force on the edge region of the material piece is no longer exerted, and the material piece is further transported using only the transport means. Such a configuration and alignment is preferably performed on both the left and right sides adjacent to the transport means, thereby exerting a tensile force correspondingly on the edge region on the one hand and a tensile force acting appropriately on the material piece on the other hand. Equilibrium with force is obtained, which results in accurate target alignment of the material piece.

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

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

Alignment is possible even when the alignment is not exactly parallel, because the equilibrium is obtained by the action of appropriate forces, which ultimately ensures the desired alignment.

In addition, tension is preferably provided 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.

While applying a force, particularly a tensile force, the force or the means applying the tensile force has an angle with respect to the transport direction in the transport direction, preferably parallel to the transport direction of the transport means. It is very special to be moved to or to bring one kinetic component relative to the strip material in the transport direction, preferably parallel to the transport direction.

This is achieved not only in dots within a narrow area, but also over a relatively large area that extends substantially parallel to the transport direction and during the transport process. But the alignment can be discontinuous or continuous.

At this time, it is particularly preferable that the movement or kinetic component of the means in the transport direction is adapted to the transport speed of the transport means, thereby avoiding the folds of the strip-shaped material.

When a material piece has a sensory or optically recognizable edge or outer edge, or markings, lines or steps extending parallel to the transport 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 initiating technical means for accurate target alignment of the material piece.

With respect to the device, the problem set above is solved by the device according to claim 21.

The tack piece is automatically supplied to the station, preferably via a pre-positioned device portion or manually by an operator. The transfer device is connected to or built into the station so that the station itself is the transfer device for receiving the tack piece, or in some cases, the transfer device already starts in front of the station. It may have been provided so that the tack piece can be transported from or through the station to a transport device connected to the station. The tacking piece is conveyed into the processing station through the transfer device using a transfer device.

Post-correction of the tack piece is performed by the inspection station and the correction station, so that the alignment of the tack piece that deviates from the target position during delivery or while being conveyed through the device is for the tack. The piece is a machining station and has been modified before the tack piece is fed to the machining station where the tack piece is machined within the machining station. This guarantees particularly good quality of intermediate or final products.

The inspection station may be located in front of the correction station, whereby the inspection is carried out first and then the correction is carried out. An alternative or additional inspection station may be postponed to the machining station, which inspects 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 allows non-contact detection of marking layouts, preferably sensored detection using the human eye or appropriate equipment. Alignment of the tack piece can be inspected at the outer edge because the edge is sensor-recognizable, or at the pile edge of the textile tack piece, but detection should be based on markings such as the handle. 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 the correction value or the correction specification is specified.

The modification value is supplied by a person at the time of inspection, and the person performs a comparison between the marking layout and the target marking layout, and identifies which modification value should be set based on the experience value, for example.

Alternatively, the comparison is carried out by reasonable technical means for data processing and modified specifications have been created.

The alignment correction is subsequently performed by the correction station, which performs accurate alignment of the tack piece based on the correction value or the correction specification.

Inside the processing station, intermediate or final products of excellent quality are manufactured. The processing station may be a fixture, in which the tack piece is, for example, hemmed or sewn. However, any other machining step may be performed.

Preferably, the inspection station has a detection device for sensor-based detection of the actual marking layout, a marking layout that is detected while being combined with the detection device, and a target marking layout that is preferably stored in electronic storage. It is practiced to have a processing device for comparing, evaluating deviations, and possibly 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, and the storage stores at least one target marking layout, and the processing device accesses the 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 calculates the modified specifications and supplies them. The modified specifications are then communicated and displayed on the display panel. The modified specification may be supplied as an alternative corresponding control signal and may be transmitted directly to the control unit of the modified station.

Suitably the detection device is made to have a camera or a sensor device with at least one sensor.

The marking layout can be recognized non-contactly by a sensor device or a camera.

Preferably, the sensor may be an optical sensor or a sensor that performs distance measurement.

Optical sensors can be used to optically detect the marking layout. At this time, for example, a color or a pattern can be detected. However, marking layouts of different pile height types on the surface of the tack piece may be detectable. The marking layout of the model can also be optically detected. Alternatively, the marking layout of the type can also be detected via distance measurement. Therefore, a sensor for performing distance measurement is provided, and the sensor detects the distance to the pile tip.

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

A light source is provided facing the sensor device or camera so that the light source transmits the tack piece so that the sensor or camera can better recognize the markings on the tack piece capable of transmission.

Suitably the processing equipment may have a computer with storage and at least one target marking layout stored in the storage for comparison with the actual marking layout.

The computer may store different target marking layouts, or later program new target marking layouts for a new production line. These are then selected according to the production line and are available for comparison with the corresponding marking layouts detected.

Preferably, the modification station has a control unit coupled with an operating element for inputting modification values and optionally modification 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 operation element, and the operation element transmits the corresponding control signal to the control device. The correction station corrects the alignment according to the input.

The modification can be performed, for example, by a suitable mechanical member, the control unit controls the mechanical member according to the modification value or the modification specification, whereby the mechanical member exerts a corresponding mechanical action on the tack piece. Make corrections and align the tack piece in the correct position.

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

The display panel may be, for example, a monitor, on which the modified specifications are displayed and can be read, whereby the modified specifications can be subsequently input to the operating element. As a result, the alignment of the tacking piece can be manually corrected.

Alternatively or additionally, the inspection station is coupled to communicate directly with the modification station, and the modification specification uses the signal generated by the inspection station's computer to directly control the modification station. What has been introduced into the unit may be done.

As a result, automatic correction is performed according to the correction specifications without human assistance.

The present invention is also a device for aligning a plane region or an edge region of a material piece preferably having flexibility, particularly a fibrous tack piece, particularly to the exact alignment according to claim 21. With respect to the correction station of, the plane of the material piece comprises at least one driven transport means, in particular a transport device having a mechanical frame for the material piece, comprising a transport belt, and preferably a support member for the transport means. The area near the area or edge area relates to a device capable of transporting in the transport direction.

One evolutionary configuration is proposed to ensure the precise formation of the planar or edge regions of the material pieces of the textile tack piece type in a simple manner.

It is proposed here that the device has at least one control means, particularly in order to carry out the method according to any one of claims 12 or 18 to 20, wherein the control means is basic. At the position, the working member of the control means is at the working position from the basic position outside the plane stretched by the material piece at the basic position, and the control means is at least approximately aligned with the plane. The control means can be adjusted and moved to the action position where the material piece is held while being tightened, and the control means is moved in the direction across the transport means and in the direction across the transport direction during the adjustment movement at the action position.

At this time, it is preferably performed that the apparatus has control means on both sides of the transport device.

At this time, it is preferably performed that the apparatus has a second transport device and control means provided on both sides of the transport device.

This configuration allows alignment on both the left and right sides adjacent to the transport means, thereby achieving a balance between the force acting on the edge region accordingly on the one hand and the force acting on the material piece accordingly on the other hand. This results in accurate target alignment of the material piece.

FIG. 1 is a method for accurately positioning and processing a piece 1 for tacking, such as a textile product, and is a step of the following method, that is,
Step 3 of mechanically or manually supplying the (spare) aligned and / or positioned tack piece 1 to the device 2 or the station 9 of the device 2.
Step 4 of inspecting the alignment and / or positioning of the tack piece, preferably marking the tack piece provided on the surface of the tack piece or in the weave of the tack piece. Is sensor-based and the actual marking layout is compared to the target marking layout.

Step 6 of transmitting the correction value or the correction specification to the correction station 12 and
In step 7, the alignment of the tack piece 1 is manually or mechanically corrected by using the correction station 12 according to the correction value or the correction specification, and the detected marking layout becomes the target marking layout. The step to be matched and / or the tacking piece 1 in the transport direction 23 to the machining station 13 for machining the tacking piece 1, preferably a fixture, to which the machining step is performed in the fixture. Step 8 to supply and
In some cases, a method having an individual method step or a step in which a plurality of method steps are repeated is shown schematically.

The tack piece 1 can be manually removed by an operator, for example, from a pre-installed device portion or from a storage location. After that, the worker manually aligns or positions the tack piece 1 before supplying the tack piece 1 into the station 9, and the worker subsequently manually transfers or manually transfers the tack piece 1 into the station 9. insert.

Alternatively, the automatic (spare) alignment or positioning of the tack piece 1 is, for example, a preceding device portion in which the tack piece 1 is (spare) aligned, followed by the station 9. It is possible in the equipment part that is automatically transferred or supplied to.

After the tack piece 1 is supplied into the station 9, the alignment and / or positioning of the tack piece is inspected at the inspection station 11 and the modification 7 is performed at the modification station 12 if necessary.

Therefore, the tack piece 1 is transported by the transport device 10 so as to pass through the device 2, and the steps of the method preferably elapse while the tack pieces are continuously or discontinuously transported. Inspection 4 and modification 7 while the tack piece 1 passes through the device 2 is particularly advantageous, but it can cause the tack piece 1 to shift, especially during transport, and the tack piece 1 before machining. This is because the supply 8 to the machining station 13 and the modification 7 may be required prior to the implementation of the machining step for accurate alignment. Continuous transport makes the method particularly economically feasible and can achieve speeds of 20 m / min.

Alternatively, the inspection 4 of the tack piece 1 is performed for the first time after processing in the processing station 13. The progress of this method is not shown in FIG. When the deviation of the marking from the target marking layout, for example, the seam provided during machining deviates from the target layout, the deviation is detected after machining, the correction specification or correction value is specified, and the correction value is specified. The modification specification or modification value is transmitted to the modification station 12. The correction station 12 then makes the corresponding modifications for the subsequent tack piece 1 so that the subsequent tack piece 1 is correctly aligned prior to the supply 8 to the machining station 13.

The inspection 4 is performed by non-contactly detecting, for example, the marking of the tack piece 1 optically. The markings are preferably provided on the surface of the tack piece, for example, in the form of a pattern, or in the weaving of textiles, for example, in the flow of weaving threads, or in the form of markings of weaves such as meshes, seams, etc., and are optically detected. However, other detection elements capable of non-contactly detecting the marking may be provided. For example, it is possible to detect markings of different pile height types by distance measurement. Therefore, a sensor for performing distance measurement may be provided, and the sensor detects the distance to the pile tip. If no deviation is confirmed during inspection 4, correction 7 is not required and the method elapses according to the dotted line Y, whereby supply 8 to the machining station 13 is performed after inspection 4.

Optical detection can be performed with the human eye or through a suitable optical device. The optically detected marking layout is compared to a predetermined target marking layout. This is also selectively performed by a person or by a suitable processing device 15, preferably a data processing device.

When the detection and comparison should be done by the operator's eyes, the target marking layout is, for example, a transfer base, where the tack piece 1 is displayed on or formed by the transfer base. It may have been done. However, any other suitable practice is possible in which one can visually compare the marking layout with the target marking layout. The operator recognizes the deviation of the tack piece layout from the target layout and identifies the correction value. The operator can identify the modification value based on the empirical value and preferably transmit it to the modification station via manual input to the operating element 20 coupled to the modification station 12, thereby depending on the modification value. The manual correction 7 is carried out. Recognition by the optical device is preferably performed by a sensor device 17 equipped with at least one sensor or by a camera, and the tack piece 1 is transported through the sensor device 17 or the camera by the transport device 10 and tacked. The marking on the piece 1 is optically detected.

The sensor device 17 or camera preferably detects the actual path and direction of deviation, thereby confirming an accurate marking layout. With respect to the direction, it is detected whether the deviation is on the left side or the right side in the direction crossing the transport direction 23. The path is also detected accurately, i.e., how much deviation there is. The route may be confirmed, for example, in mm. These imagings are then compared to the target marking layout, which allows accurate correction specifications to be created with the 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 has a computer 19 and a storage 16 coupled to the computer, in which at least one target marking layout is stored, and the target marking layout is compared with the actual marking layout. To. A number of different target marking layouts may be programmed and stored in the storage 16 and the 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 modification specification and supplies the modification specification to carry out the modification 7. The modification 7 can then be performed automatically by transmitting the modification specification as a corresponding control signal to the modification station 12, and the modification station automatically implements the modification 7 according to the modification specification. No human intervention is required, and a fully automatic correction 7 for aligning the tack piece 1 is performed.

Alternatively, the calculated modification specification may also be displayed on a display panel 22 such as a monitor, whereby the operator can read the specification and enter it into the operating element 20 that communicates with the modification station 12. can. The modified specifications are displayed, for example, in numerical values or equivalent types, and may be read by the operator. The operation element 20 is preferably coupled to the modification station via the control unit 21 of the modification station 12, and the control unit 21 controls the modification station 12 in response to an input to the operation element 20.
The operating element 20 and / or the display panel 22 is additionally an automatic correction 7, and even in an automatic correction in which the control signal is directly guided to the correction station 12, for example, when the automatic machine fails. It may be provided for safety or for individual adjustment.

The modification station 12 subsequently performs modification 7 according to the modification value or according to the modification specifications, whereby the marking layout is matched.

The modification 7 can preferably be performed by transmitting the modification value or modification specification to the control unit 21 of the suitable mechanical member, and the control unit 21 can perform the modification value according to the modification specification or according to the modification value. Under control, the mechanical member performs the modification 7 by exerting an appropriate mechanical action on the tack piece 1 to align the tack piece 1 with the correct position. The modification 7 is performed in both directions crossing the transport direction 23, because the tacking piece 1 may be displaced in both directions across the transport direction 23, and the modification 7 is required in both directions. Only then can accurate alignment be achieved. Such post-correction of the tacking piece 1 along with the marking layout allows accurate positioning of the tacking piece 1 in the apparatus 2, thereby allowing accurate machining of the tacking piece 1 in the machining station 13. This produces particularly expensive, high-quality products. Therefore, preferably, the inspection 4 and the modification 7 are performed immediately before the machining step, whereby the tacking piece 1 is supplied to the machining section in an accurately aligned state.

In addition, inspection 4 with a non-contact sensor also allows for alignment of edgeless tack pieces, thereby based solely on the pattern or, in the case of textile tack pieces 1, fibers such as weaving thread flow. Individual and accurate alignment and positioning can be performed based solely on the product markings. The tack piece 1 can be machined in any way, for example a hem may be sewn, or the tack piece 1 may be folded. If, for example, a further machining step is followed by a further machining step in which the tack piece 1 must be accurately aligned in the further machining step, a new inspection 4 and modification 7 may be performed. The steps of the method can be repeated at any frequency.

FIG. 2 shows a schematic configuration of an apparatus 2 for carrying out the method according to claim 1, wherein the apparatus 2 is:
A station 9 to which the tack piece 1 is supplied manually or mechanically (preliminarily) aligned and / or positioned.
A transport device 10 connected to the station 9, optionally starting in front of the station 9, for transporting the tack piece 1 so as to pass through the device 2.
In the inspection station 11, whether the actual marking layout of the marking of the tack piece 1 is preferably detected by the sensor in the inspection station, can be compared with the target marking layout, and the correction value or the correction specification is created. , Inspection stations that can be created, and
A correction station 12 for accurately aligning the tack piece 1 according to the correction value or the correction specification, and
It has a processing station 13, preferably a fixing device, wherein the tacking piece 1 is supplied in a state of being accurately aligned and can be processed in the fixing device.

The tack piece 1 is supplied to the station 9 in a (spare) aligned state automatically, preferably from a fronted device portion, or manually by an operator.

The transport device 10 is connected to the station 9, and the station 9 itself is the transport device 10, and the tacking piece 1 is supplied to the transport device, or in some cases, the transport device 10 is already in the station 9. It is provided to start in front of, whereby the tacking piece 1 can be transported from the station 9 or through the station 9 to the transport device 10 connected to the station. good.

The station 9 may be any other station 9 for carrying out a machining step, for example.

The tack piece 1 is conveyed to the processing station 13 through the device 2 by using the transfer device 10 and past the inspection station 11 and the correction station 12, or through the inspection station and the correction station. The inspection station 11 may optionally be retrofitted to the processing station 13, which is not shown in the figure. In this case, the inspection 4 is performed for the first time after the processing of the first tack piece 1. 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, whereby the alignment correction is performed before processing. Post-correction of the tack piece 1 is performed by the inspection station 11 and the correction station 12, whereby the alignment of the tack piece 1 deviated from the target position at the time of delivery or while being conveyed to pass through the device 2. Is modified before the tack piece is the machining station 13 and the tack piece 1 is fed to the machining station where the tack piece 1 is machined into an intermediate product or a final product in the machining station. This guarantees particularly good quality of intermediate or final products.

FIG. 3 shows a first variation of the device 2. The inspection station 11 makes it possible to detect the marking layout in a non-contact manner. The inspection station 11 has a detection device 14 for that purpose, and the detection device is a sensor device 17 including a camera or at least one optical sensor. The layout of the tack piece 1 can be detected thereby and the edges are optically recognizable so that they are outer or pile edges and can be aligned based on the outer or pile edges. Although pile edge detection is possible, an outer edge or pile edge is not always necessary, as optical detection based on any pattern or such marking is also possible. Alternatively, markings can also be detected by distance measurement. Therefore, a sensor for performing distance measurement is provided, and the sensor detects the distance to the pile tip. After that, in the processing device 15 of the inspection station 11 that is coupled to the detection device 14, the detected marking layout is compared with the target marking layout, and the modification specification 5 is specified. This is done by appropriate technical means for processing the data, and in the embodiment a computer 19 connected to the storage 16 is used. The marking layout detected by 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 then performs a comparison between the marking layout and the target marking layout stored in the storage 16, where the storage 16 may store different target marking layouts, or later new for a new production line. You can program a target marking layout. These are then selected according to the production line and are available for comparison with the corresponding marking layouts detected.

When the marking layout has a deviation from the target marking layout, the computer 19 calculates the correction specifications. The modified specification is transmitted to the receiving unit of the modified station 12 via appropriate technical means, and the modified station makes the modification 7 according to the specification.
The modification specifications are transmitted to the control unit 21 of the modification station 12, for example, by the type of the control signal of the computer 19.

In this case, the inspection station 11 is coupled to communicate directly with the modification station 12. As a result, accurate correction 7 is automatically performed according to the correction specifications without human assistance.

The modification 7 can be performed by, for example, a suitable mechanical member, the control unit 21 controls the mechanical member according to the modification specifications, and the mechanical member exerts a corresponding mechanical action on the tack piece 1. The correction 7 is carried out by the above method, and the tack piece 1 is aligned with the correct position.
If there is no deviation, correction 7 is not performed.

Subsequently, the tack piece 1 is supplied to the processing station 13. The processing station 13 may be a fixture, in which the tack piece 1 is, for example, hemmed, bonded or sewn. However, it may be an apparatus for folding the tack piece 1 or an apparatus for carrying out any other processing step.

At the processing station 13, an intermediate product or a final product having excellent quality is manufactured.

The second variation 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 referenced for comparison is a transport base and the tack piece 1 is displayed on or formed by the transport base on which the tack piece 1 is transported. It is done by. The operator recognizes the deviation of the tack piece layout from the target layout and identifies the correction value. The operator can identify the modification value based on the empirical value and transmit it to the modification station via the manual input to the operation element 20 coupled to the modification station 12, thereby manually according to the modification value. Formula modification 7 is implemented. The modification station 12 has an operating element 20 for that purpose.

The third variation is shown in FIG. The detection and comparison are performed in the same manner as in the first embodiment, that is, in the inspection station 11 by the detection device 14 (eg, sensor) and the processing device 15, and the computer 19 of the processing device 15 is 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 specifications are read and manually input to the operating element 20 coupled to the modification station 12. The correction station 12 has a control unit 21 coupled to the operation element 20, and is controlled by the control unit in response to an input.

The fourth variation 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 tack piece 1 is conveyed so as to pass through the device 2, it is provided between the sensor device 17 and the light source 18, and is transmitted and irradiated by the light source 18, whereby the sensor is, for example, the textile tack piece 1. The markings in the weaving of the fibers can be better recognized.

Using the above methods and devices, not only fibrous tack pieces but also tack pieces made of any material that can be processed in the same manner as the fibrous material are handled. This includes, for example, a tack piece made of paper or plastic.

The additional device shown in FIGS. 7-11 helps to align the edge region 101 of the material piece 102, which preferably has flexibility. The device can be used, for example, as a correction station 12 for accurate alignment within the device 2. The material piece 102 is, in particular, a textile material piece that is separated from the fiber web and has a quasi-rectangular basic shape. The device is substantially from a transport device 103 having an implied mechanical frame 104 for the material piece 102, comprising a transport means 105 driven, eg, a transport belt, and a support member 106 for the transport 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 type of transport means 105 of the belt drive unit is placed on the upper side of the material piece 102, whereby the material piece is pressed against the support member 106. The support member 106 is preferably a flat and smooth plate. The transport means 105, which is preferably formed as a transport belt for the belt drive unit, is combined with a spring-loaded support block 107 on the upper side, and the support block elastically moves the transport means 105 toward the support member 106. Press in a prestressed state. These support blocks 107 are held by the constituent members of the machine frame 104. The visible portion of the machine frame 104 is formed as an L-shaped bent metal sheet, one leg of the metal sheet 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 region 101 of the material piece 102, is held in a tightened and fixed state between the support member 106 and the transport means 105, or can be tightened and fixed and transported. It is transported in parallel to the edge region 101 in the transport direction 108 by the means 105. As is well recognized in FIGS. 7-11, the edge region 101 is formed to extend into a pseudo-waveform to clarify the alignment task, whereby the edge region is transported. It is not aligned exactly parallel to the direction, has a different shape with respect to the transport direction, and extends at different distances from the transport means 105.

The support member 106 projects from the transport means 105 on both sides in a direction crossing the transport direction. The protruding region is described by 109 or 110. In both projecting areas 109, 110 in the embodiment, recesses 111, 112 having outer edges 113, 114 oriented parallel to the transport direction 108 are provided, the outer edges of which are the transport means 105, respectively. Is adjacent to. Instead, it is assumed that one outer edge 115, 116 of each of the projecting regions 109, 110 of the support member 106 is used depending on the purpose, and the outer edge 115, 116 is also directed parallel to the transport direction 108. ing. Further, one control means 117, 118 is indirectly fixed to the machine frame 104 on the outer edge 113 or 114, and possibly on the outer edge 115 or 116, respectively, and the control means is a basic position. For example, as shown in FIGS. 7, 9 and 10, the outside of the plane in which the working member of the control means is stretched by the gap between the support member 106 and the transport means 105 at the basic position. In the embodiment, it is possible to adjust and move from the basic position on the plane to the action position, the action position is shown in FIGS. 8 and 11, and the control means presses the plane at the action position. That is, it is pseudo-positioned below the protruding region 109 or 110 by the member.

The control means 117 or 118 has an outer edge 113 or 114, or, as is apparent in FIGS. 8 and 11, during the adjustment movement in the direction across the transport direction 108 and in the direction across the plane above. It also passes through 115, 116 and is moved with a region of material piece 102 that has a relatively narrow distance to the outer edge and is adjacent to the transport means 105.

Therefore, depending on the required alignment, 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. 11, a lateral force is applied to the corresponding edge region 101 or region 101a of the material piece 102. The lateral force moves the material piece 102 in the area engaging with the control means 117, 118 away from the transport device 103, thereby accurately locating the layout of the edge area 101 as desired. Match.

In order to ensure that the edge of the material piece 102, particularly the material piece 102, is entrained when the control means 117 and 118 are adjusted and moved from the basic position to the action position, the support member 106 is used in the process of the control means 117 and 118. Moreover, the swivelable support portion 119 is held at the outer edge of the recesses 111 and 112, which are in front of the recesses in the transport direction, and the control means 117 is used for adjusting and moving to the action position. , 118 partially presses the support and pushes the support downward, eg, across the transport direction, as is apparent in FIG. The edge region 101 of the material piece 102 provided between them is fixed between the control means 117, 118 and the support portion 119, whereby the edge region 101, as is revealed with reference to FIG. Is moved downward so as to cross the transport direction 108 as desired. The length of the stroke of adjusting and moving the control means 117, 118 from the basic position to the action position for the purpose of accurately aligning the edge regions 101, 101a of the material piece 102 can be adjusted by, for example, an operator. Therefore, a relatively large adjustment movement stroke or a relatively small adjustment movement stroke is carried out according to the deviation of the outer edge of the edge regions 101, 101a from the target position.

The support portion 119 is particularly elastically movably fixed to the support member 106, especially to the outer edges of the recesses 111, 112 in front in the transport direction 108.

As a result, it is achieved that the support portion 119 is automatically moved according to the adjustment movement stroke when the control means 117 and 118 are adjusted and moved.

It is not shown in the figure that the control means 117, 118 are formed as non-slip, rollers, or stamps at the free end of the control means facing the material piece 102. This is a possible configuration. However, at this time, it is assumed that the operation of the control means, that is, the adjustment movement of the control means from the basic position to the action position needs to be performed intermittently, whereby during the transfer of the material piece 102 in the transfer direction 108, The edge regions 101, 101a, respectively under the control means, can be pulled accordingly by the control means, thereby achieving accurate alignment.

At this time, it is preferable that the control means is a belt drive unit 120, 121 including a driven roller 122 and a freely rotating roller 123, and the belt of the belt drive unit 120 or 121 is around the roller. It goes around and is moved.

A motor-type rotary drive unit 124 is held and fixed to a frame member, for example, a member of a mechanical frame 104 as a drive unit for the driven rollers 122 of the control means 117 and 118, and the motor-type rotary drive unit is coupled. Means 125, in the embodiment, are coupled to the drive shaft 126 via a drive belt. The drive shaft 126 additionally has a roller 127 fixedly coupled to the shaft for this purpose. The drive shaft 126 is supported and guided within the mounting block 128, which is also frame-fixed to the members of the machine frame 104. The drive shaft 126 is fixedly coupled to the driven rollers 122 of both control means 117 and 118, whereby the belt drive units 120 and 121 are moved via the rotation of the drive shaft 126. The orbital direction of the coupling means 125 (of the drive belt) is described in 129. In addition, the control means 117 and 118 can be adjusted and moved by using the actuator 130 fixed to the mechanical frame 104. Therefore, the actuator 130 is composed of, for example, an electric motor type drive unit 131, and the electric motor type drive unit can be alternately operated only in the right direction and the left direction. The disk-shaped driver 133 is rotated clockwise or counterclockwise through the output shaft 132 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 can be swiveled around the drive shaft 126 via the coupling rods 134, 135 and the coupling rods 136, 137. By rotating the driver 133 in one direction (for example, clockwise) using the drive unit 131, the entire element having the belt drive unit is swiveled from the basic position to the action position, so that the control means 117 is moved to the action position. The roller 123, which is adjusted and moved and freely rotates at the action position, is adjusted and moved downward, as is apparent in FIG. 11, for example. This movement of the driver 133 lifts the control means 118 on the other side. When the rotation direction of the driver 133 is opposite, the control means 117 is lifted, the control means 118 is similarly lowered, and the freely rotating roller 123 in the control means is moved downward. With this configuration, both control means 117,118 cannot act on the material piece at the same time, and only the selected control means 117,118 act on the material piece, as should be determined by the user. It is ensured that it can be done.

Guides provided at an angle following the recesses 111, 112, respectively, to perfectly guide the edge regions 101, 101a of the material piece 102 in the transport direction 108 even after passing through the recesses 111, 112. A portion 140 is installed, and the guide portion moves steplessly in the transport direction into the region following the projecting region 109 or 110 of the support member 106.

In the embodiment, the control means 117 and 118 are formed by an actuator that orbits in the same direction with respect to the transport direction 108, particularly the belt drive units 120 and 121, and the orbiting actuator has at least a corresponding control means at a basic position. It is continuously orbitally driven when it should be adjusted and moved from to the acting position and between the acting positions. Thereby, the edge regions 101 and 101a are machined according to the transport direction and the transport speed of the material piece 102, whereby the alignment of the edge regions 101 or 101a is achieved in the correct manner.

The positions of the edge regions 101, 101a deviated from the target position can be visually detected by the operator, whereby the operator can operate the corresponding device according to the regulation. However, the edge regions 101, 101a or the outer edge of the edge region is detected with respect to the position of the edge region using a suitable detection device, and the control means 117, 118 are operated according to the specified by the corresponding mechanical control. It is also conceivable and possible.

The apparatus shown in FIGS. 7 to 11 is suitable and defined to enable a method for aligning the material piece 102, in particular the edge regions 101, 101a of the fibrous tack piece. Therefore, the material piece 102 is conveyed in parallel to the edge region in the transport direction 108 by using a transport device, for example, a transport means 105, near the edge regions 101 and 101a. At this time, the material piece is pressed against the support member 106 of the transport device 103 by using the transport means 105 driven by the transport device 103, and is transported along the support member 106 in the transport direction. The methods of equipment and methods described may, of course, be provided on both sides of the material piece 102, whereby equipment corresponding to both edge regions is arranged and mounted. The material pieces may hang freely, for example, by forming a loop between the equipment members provided on both sides.

The support member 106 projects from the transport means 105 on both sides in a direction crossing the transport direction 108, as specified. Recesses 111, 112 are provided in both protruding regions 109, 110, which recesses are below the corresponding regions of the material piece 102. The alignment of the material piece 102 is offset from the exact target alignment of the material piece 102, i.e., extending with the edge region 101 or 101a of the material piece moved closer towards the transport means 105. When, the region or edge region 101, 101a of the material piece 102 aligned with the deviation passes over the edge of the support member 106 extending parallel to the transport direction 108, or is transported. It 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 crossing the transport direction 108 and in the direction across the transport means 105. , Moved away from the transport means 105 by a corresponding amount, i.e. pulled away, thereby correcting the misaligned alignment of the material piece 102 and shifting it to an accurate target alignment.

The tension acting on the strip material within the region of the corresponding control means 117, 118 is brought about by the action of vertical forces, whereby good force transmission and alignment is achieved. While the tensile force is applied, the means for applying the tensile force is preferably interlocked in parallel with the transport direction 108 of the transport means 105, or an additional moving component parallel to the transport direction 108 is added to the strip-shaped material. Bringing in, thereby avoiding distortion of the material piece. The movement or kinetic components of the means parallel to the transport direction 108 are adapted to the speed of the transport means 105, thereby achieving a smooth action on the strip material, especially avoiding folds. To facilitate alignment, the material piece 102 has markings, lines or steps extending parallel to a visually recognizable edge or outer edge or transport direction 108, thereby from target alignment. The eccentric alignment is recognized by means of implementing or monitoring the alignment method and initiating technical means for accurate target alignment of the material piece. The monitoring means may be the eyes of the operator, or may be electrical, electronic, or other detection means.

With the devices and methods described, it is possible in an outstanding manner to position the edge areas of the flexible material pieces appropriately as specified, thereby forming the subsequent hem and Work processes such as hem sewing can be mechanically connected. The alignment is particularly performed during the normal operating mode of the transport device 103, which allows accurate alignment during the normal transport process.
