Definitions

  • the invention relates to a method and a device for sewing labels under a fabric in a sewing machine. Such a method is required, for example, to sew a label onto the inside of the bundle of laundry items.
  • a slide-in device as is known, for example, from DE 27 32 488 C3, which goes back to the same applicant, and from CH 634 617.
  • the clamping device was pivoted according to the subject of this patent, i.e. the clamped label was fed into the sewing area (into the gripping area of the fabric feeders) due to a swivel movement.
  • the label could accidentally be sewn on at an angle, which was criticized.
  • CH 634 617 shows a further feed device for feeding labels under a fabric, which is placed on a needle plate, the feed device also consisting of a swiveling gripper clamp, between the gripping jaws of which the label is clamped.
  • This clamping device had no feed device. It was arranged directly in front of the fabric feeder, so that here again there was the disadvantage that the label to be sewn was taken over directly by the clamping device into the fabric feeder and was guided by it into the sewing area. Here, too, there was a risk that the label could warp due to a different transfer process from the clamping device to the fabric feeder and was accidentally sewn on at an angle.
  • the invention is therefore based on the object of developing a method and a device operating according to the method so that a clean feeding of the label into the sewing area is possible with a label to be sewn under a fabric, without the risk that the label on Fabric is sewn at an angle or offset.
  • the invention proceeds from the known method steps 1 to 4 mentioned above and provides for further steps essential to the invention:
  • the label is still held in a clamped manner and is guided in the sewing area in a clamped manner, whereby it is passed across the fabric feeders in a clamped manner and the label is held in a clamped manner until at least one One third of the label width the seam was completed.
  • An essential feature of the present method is therefore that the label with the clamping device and the associated feed device is no longer required only in the area of the material conveyor arranged in front of the sewing device, but that it is still held in a clamped manner and guided over the material conveyor in this clamping position is so that it is clamped in the sewing area and is held clamped until it is clearly fixed to the fabric by means of a seam.
  • Such a clear fixation is given, for example, when at least a third of the entire label seam has been clamped.
  • the invention is not limited to this; it can also be provided that the clamping device is only effective until, for example, a quarter of the total seam to be made over the label has been completed.
  • the clamping device After completion of the seam, which is sewn when the label is clamped, the clamping device is opened and the label and the fabric are continued in a manner known per se with the fabric transporter.
  • the clamping device is designed as a slide on which at least one holding clamp is arranged, the slide being arranged on a fixed guide and the feed device essentially consisting of a spindle on which a spindle nut is mounted is movable, which is fixedly connected to the carriage. It is further preferred here if the spindle is driven by a stepper motor, because the control of such a stepper motor enables a particularly sensitive and speed-accurate control of the rotational speed of the spindle.
  • the feed device consists of a direct current synchronous motor which is coupled to a control circuit (angle encoder).
  • angle encoder angle encoder
  • the angle of rotation of the motor is precisely controlled by means of a control circuit, so-called angle of rotation encoders being used which make an exact, step-by-step, angle-dependent rotation of the direct current motor possible. In this way, it is possible to either drive the spindle via the above-mentioned rotary motor or also direct drive by means of such a direct current motor.
  • the third embodiment which provides a so-called linear motor, points in the same direction.
  • a linear motor is also controlled by means of direct current, cyclically and enables linear displacement via an exact, defined clock frequency, which brings about a defined displacement of the linear motor.
  • the feed device consists of a pneumatic cylinder which also advances the carriage drive in a defined manner.
  • All of the exemplary embodiments have in common that the feed speed is exactly synchronized with the sewing speed. This can also be done by a mechanical positive coupling between the feed of the material and the feed of the mentioned clamping device.
  • the clamping device is effective until the label is sewn to a large extent to the fabric and there is no longer any danger that the label may warp or twist due to the further feed in the feed dog.
  • a device for carrying out the method also provides that the entire feed device is arranged next to the presser foot.
  • the insertion of the label in front of the fabric feeder is thus avoided and the clamped label is moved over the fabric feeder to such an extent that it certainly comes into the needle area and thus into the stitch area of the needle plate.
  • FIG. 1 schematically, in plan view, an arrangement according to the invention with a label in the sewing position
  • FIG. 2 a section through a detail in FIG. 1,
  • FIG. 3 a perspective side view of the fabric to be sewn with the label inserted
  • Figure 4 is a perspective view of the clamping
  • the method provides that the label 10 to be clamped is first clamped in a position 43 (preparation position) in a clamping device 8.
  • the clamping device 8 is moved back into the retracted position (arrow direction 13 ') and the feed device 12, which drives the clamping device in the direction of displacement, is also in the retracted position.
  • the throat plate essentially has a front edge 7 located in the sewing direction, an outer side edge 6, an inner side edge 5 and a rear edge.
  • the clamping device consists essentially of Figures 1 and 4 of a bracket 9 which is rotatably held with a connection 21 in a cross member 23.
  • the cross member consists of two mutually parallel and fixed to each other support legs 20, 22, which are firmly connected to each other by said cross member 23.
  • the cross member 23 is fixedly connected to a carriage 24 which is guided on a fixed carriage guide 25 in the direction of arrow 13 and in the opposite direction.
  • a piston-cylinder arrangement 31 is articulated on the crossbeam 23 via a pivot bearing 34, the piston rod 32 of which engages on the free, pivotable end of a lever 30, the other end of which is connected to the connection 21 in a rotationally fixed manner.
  • the connection 21 thus forms a pivot axis 33 for pivoting the clamp 9.
  • the clip is thus designed as a lever that can be pivoted on one side and is fastened to the support bracket 11.
  • the feed device 12 consists essentially of a spindle nut 26 which is fixedly connected to the cross member 23. This spindle nut 26 is displaceable on a spindle 27 in the arrow directions 13, 13 ', the spindle being held between two bearings 28. The two bearings are arranged in a carrier 29 which is fixedly attached to the sewing machine arm 1 as an angular carrier.
  • the spindle 27 is driven here by a belt wheel 36 which is driven by a toothed belt 35 which is looped by a further belt wheel 37 which is connected in a rotationally fixed manner to a drive shaft 38 which is driven by a stepper motor 42.

  • the feed device 12 is started and the label 10 held in the bracket 9 in the support frame 11 is guided with its front edge from position 43 into the sewing area in the direction of arrow 13, the stepping motor 42 correspondingly drives the spindle 27 and the spindle nut is moved in the direction of arrow 13 upwards in FIG. 1.
  • the label is introduced directly into the sewing area, i.e. thus in the area of the tap hole 4, which is shown in FIG. 1 as a single tap hole and in FIG. 4 as a double tap hole.
  • FIG. 3 shows only for the sake of clarity that the lower edge of the fabric in FIG. 3 is folded up to make it clear that this label 10 is sewn to the underside of the fabric. In practice, however, this folded-up edge is arranged exactly flush on the throat plate 17 and below the presser foot 16.
  • FIG. 3 also shows a further variant, namely a variant in which no rubber 14 is used, but a bead which is folded in the form of a fold and surrounds the fabric.
  • the label is sewn using either a double needle 18 and a double seam 41 or a single seam 19.
  • the design of the feed device as a spindle drive in conjunction with a stepper motor results in the essential advantage that the feed movement of the clamping device 8 in the sewing direction 13 can be precisely synchronized with the transport speed of the conveyors 2, 3. Therefore, after the label has been fixed with the help of the seams 19, 41, the label on the fabric is secured absolutely securely, without the risk that the transporters 2, 3 will bend, tilt or angle the label.

Abstract

L'invention concerne un procédé ainsi qu'un dispositif permettant de coudre des étiquettes sous une étoffe dans une machine à coudre. En plus des étapes de procédé connues selon l'état de la technique, à savoir le pincement de l'étiquette dans un dispositif de pincement, l'insertion de l'étoffe sous le pied de biche, sur la plaque à aiguille, la réalisation d'une couture sur l'étoffe, l'avancement du dispositif de pincement à l'aide d'un dispositif d'avance, de telle sorte que l'étiquette parvienne au moins à une zone du transporteur d'étoffe, il est également prévu, selon l'invention, que le dispositif de pincement, avec le dispositif d'avance, amène l'étiquette encore pincée sur les transporteurs d'étoffe et pince ladite étiquette jusqu'à ce qu'elle soit fixée de façon évidente à l'étoffe. Ce n'est qu'après cette opération que ce dispositif de pincement est ouvert et que l'étiquette, avec l'étoffe, est transportée plus loin par le transporteur d'étoffe. La vitesse d'avance du dispositif de pincement est de préférence synchronisée avec la vitesse du transporteur d'étoffe et avec la vitesse de couture. Pour la mise en oeuvre du procédé, plusieurs modes de réalisation sont décrits, lesquels présentent la caractéristique commune résidant dans le fait que chaque fois le dispositif d'avance dans son ensemble est disposé à côté du pied de biche. En tant que dispositif d'avance on peut utiliser une combinaison moteur pas-à-pas/broche, une combinaison moteur synchrone à courant continu/broche, ainsi que des dispositifs d'entraînement direct à moteurs synchrones à courant continu, à moteurs linéaires à courant continu et à vérins pneumatiques.
