Definitions

  • the invention relates to a method and a device for the exact positioning and processing of textiles or fittings.
  • both textile fittings and fittings made of any material which can be processed in the same way as a textile material, are processed.
  • the textile web is aligned mechanically, for example by mechanically drawing the marginal edge or pile edge of the textile to a segmented straightening bar.
  • the straightening bar specifies the exact alignment.
  • the textile webs In order to be able to carry out such a mechanical alignment, the textile webs must have an edge that can be caught by the straightening bar in order to be able to pull the web into a desired position. This results in the disadvantage that this type of alignment without a border or pile edge, for example according to patterns or according to a thread or stitch course, is not possible.
  • the textile In addition, the textile must be endless, as is the case with textile webs. This form of alignment is not possible with textile fittings.
  • fitting pieces are then processed further, for example hemmed, folded and/or sewn, with each fitting piece being transferred automatically or manually to a device section that processes the fitting piece further.
  • the fittings are transferred by appropriate transfer and/or transport means to a station in which, for example, further processing can take place or from which the fitting is transported further. Deviations from the exact alignment of the fitting piece that resulted from cutting the (pre)aligned textile are adopted. Also in the transfer process to the station can Fitting pieces in the device slip so that they are no longer precisely aligned. It follows from this that an exact further processing of the fitting is not possible and a product of inferior quality is created.
  • a worker takes the fitted piece from the upstream processing station or a depot and feeds it to the station manually (pre)aligned, whereby the manual alignment and positioning can be carried out by the worker aligning the textile by eye or with mechanical aids and put it into the device.
  • Inaccuracies in alignment and positioning can occur with new, unskilled workers, but also with inattentiveness of experienced workers, with the disadvantage that the textile cannot be processed in an exactly aligned manner. These inaccuracies mean that the textile intermediate or end product, which is created during processing, is of inferior quality and is therefore unacceptable.
  • belt drives are used as a means of transport, which transport the fitting piece through the device via a transport plate, which, particularly in the case of particularly thick and/or flexible textiles, can result in the piece fitting in the Transport device has slipped and correct alignment cannot be ensured during further processing.
  • the object of the invention is to create a method and a device with which it is ensured that the fitting piece fed to the processing station is precisely aligned and a particularly high-quality product can be manufactured, with individual alignment also of textiles at the same time or similar fitting pieces without edges and/or pile edges is possible.
  • the fitting piece can be removed manually by a worker, for example from an upstream device section or from a depot. Before it is fed into the device, in particular the station of the device, a manual (pre)alignment or positioning of the fitting takes place, with the worker then manually feeding the fitting to the device or the station.
  • the automatic (pre)alignment or positioning of the fitting is possible, for example in an upstream device section in which the fitting is (pre)aligned or positioned and then automatically fed to the device or station.
  • the station can be, for example, a transport station that transports the fitting through the device or performs any other task.
  • the check is preferably carried out without contact, e.g. by sensory detection of markings on the adapter.
  • the markings are preferably arranged on the surface of the adapter, for example in the form of a pattern, or in the fabric of a textile, for example in the form of the course of the thread or of stitches, seams or similar fabric markings. Markings can also be formed by differences in the fabric, for example in the form of patterns formed by different pile heights.
  • the markings are preferably detected by sensors.
  • the sensory detection can take place by means of the human eye or by appropriate devices.
  • the recorded marking course is compared with a predetermined target marking course. This is also done optionally by humans or by a suitable processing device, for example a data processing device.
  • the target marking course can, for example, on the Transport document be shown or formed by the transport document over which the adapter is transported.
  • the worker recognizes a deviation of the fitting piece course from the desired course and determines a correction value.
  • the worker can determine the correction value on the basis of empirical values and transmit it to a control element coupled to a correction station, for example by manual input, so that a manual correction is carried out in accordance with the correction value.
  • the recorded marking course is transmitted to a processing station, for example, which then carries out a comparison with the target marking course, with the target marking course preferably being stored in a memory of the processing device and being available for comparison with the actual marking course.
  • the processing device calculates a correction specification, which is transmitted directly to a suitable recipient of the correction station, so that the correction station automatically corrects the alignment.
  • the correction specification calculated can also be displayed on a display panel such as a monitor, so that a worker can read this specification and enter it manually into an operating element coupled to the correction station.
  • the correction device then performs a Correction according to the correction value or according to the correction specification, so that the marking courses are at least approximately matched.
  • the correction can be made, for example, by transmitting the correction value or the correction specification to a control unit of a suitable mechanical component, with the control unit controlling the mechanical component and the latter carrying out the correction by appropriate mechanical action on the fitting and bringing the fitting into correct alignment.
  • the preferably non-contact check also enables the alignment of edgeless fitted pieces, so that an individual and precise alignment and positioning can take place solely on the basis of patterns or thread courses or similar textile markings.
  • the fitting pieces are transported through the device by a transport device.
  • the fittings can shift in the device during transport, so that a correction during transport is advantageous in order to precisely align the fitting again in front of a further processing station.
  • the method steps are carried out during the continuous transport of the fitting through the device in order to be able to carry out the method economically. Very high speeds of 20m per minute and more can be achieved.
  • the object is achieved by the method according to claim 1.
  • the fitting piece can be removed manually by a worker, for example from an upstream device section or from a depot, and fed manually to the device. Before being fed into the device, in particular the station of the device, a manual (pre)alignment or positioning of the fitting takes place.
  • the station can be, for example, a transport station that transports the fitting through the device or performs any other task.
  • the first fitting After the first fitting has been fed in, it is processed in the processing station. Its alignment and/or positioning is then checked. If deviations from the course of the desired marking are determined during the check, correction values or correction specifications are determined, which are transmitted to a correction station arranged in front of the processing station. The fitting pieces subsequently transported through the device are then aligned before being fed to the processing station according to the correction values or correction specifications.
