Definitions

  • the invention relates to a tape feed device on a sewing machine, for the automatic positionally correct sewing of tape pieces onto a material to be sewn, in particular single-bed sheets, the sewing machine having a sewing head, a sewing needle guided therein and a presser foot, and the tape feed device having a tape dispenser, a tape guide with a the course of which arranged arranged tape cutter and feed means for the tape or the cut tape pieces, wherein the tape guide is designed as a part of the length provided with a longitudinal slot guide shaft and the feed means are designed as a needle which is substantially perpendicular to the flat side facing the longitudinal slot of the band is arranged and which can be moved by associated actuating means both in the direction of its longitudinal axis and in the direction of the longitudinal slot, the lower part of the guide shaft having an arcuate shape has a curved course.
  • a tape feed device of the type mentioned is known.
  • the guide shaft for the tape to be fed runs in its end region at an angle of approximately 45 ° to the surface of the material to be sewn and ends immediately in front of a separate, conventional sewing foot of the sewing machine.
  • the orientation of the guide shaft is such that it is aligned with the longitudinal direction of the presser foot, one Adjustability of this alignment of the guide shaft is not provided.
  • This tape feed device is also rigidly connected to the sewing machine with a fixed orientation.
  • a tape feed device for a sewing machine which is arranged below the material to be sewn and leads to the underside of the material to be sewn.
  • the sewing machine is designed in the usual way with a separate presser foot, which rests on the top of the sewing material.
  • This known tape feed device can also feed tapes only in the longitudinal direction of the presser foot; for material with different For this reason, belts running in the direction of rotation also require the sewing material to be rotated between the various processing steps.
  • a further tape feed device is finally known from US-A-4 703 706, which is also specifically designed for the feeding and prestressing of elastic tapes.
  • the guide shaft runs in its lower part in the vertical direction perpendicular to the plane of the sewing material and ends just above the inlet end of a sewing foot which is also provided separately here.
  • drive rollers for conveying the elastic band are provided, which are controllable in such a way that their conveying speed is lower than the conveying speed of the sewing material conveyor under the sewing foot.
  • a change in the sewing direction and a corresponding change in the feed direction of the tape feed device are not provided here.
  • the tape feed device according to the invention can also be used without problems on automatic sewing machines, on which two symmetrical sewing heads which can be moved in the same axial direction each process one half of the sewing material. Because of the small space requirement of the new feed device, the two sewing heads can still do a great deal can be moved close to one another without there being any mutual obstruction by parts of the feed device, because the latter has no protruding and projecting parts.
  • FIG. 1 of the drawing shows a side view of the sewing head 10 of a sewing machine 1, which is equipped with a tape feed device 2.
  • a sewing needle 11 protruding downward is movably guided in the vertical direction within the sewing head 10, as indicated by the movement arrow 43.
  • a sewing table 12 can be seen, which, like the sewing machine 1, is only partially visible here.
  • a hold-down device 37 which can be actuated by means of a further piston-cylinder unit 38.
  • This hold-down device 37 serves to press the initial region of a piece of tape 20 ′ onto the sewing material 5 until the first sewing stitches are carried out by the sewing machine 1.
  • the tape feed device 2 can be pivoted about the axis x, which here runs perpendicular to the plane of the drawing, in the sense of the arrow 40 by at least 90 °.
  • the pivot bearing 21 is arranged on the upper side of the sewing head 10 and, in cooperation with the stepper motor rotary drive 28, ensures a defined angular position of the tape feed device 2.
  • the guide shaft 23 is visible in an end view of its upper end, the deflection roller 23 ′′ being arranged there to support the introduction of the tape 20 unrolled from the tape roll 22.
  • the piston-cylinder unit 26 for feeding the tape 20 is visible.
  • the piston-cylinder unit 26 is pivotally held at its upper end by means of the pendulum joint 26 'at the upper end of the shaft 23, which in turn is rigidly connected to the outer part of the pivot bearing 21 carrying the tape feed device 2.
  • the tape feed device 2 is shown in dashed lines in a position pivoted 90 ° counterclockwise, which makes it particularly clear that the tape feed device 2 can be used in a variety of ways and in particular enables the sewing of tapes onto a material 5 in different directions without the sewing material 5 having to be turned or twisted.
  • the particularly space-saving design of the tape feed device 2 allows it to be attached to sewing heads 5 of automatic sewing machines which are mirror-symmetrical and whose two sewing heads can be moved on a common axis. Because of the small throat of the tape feed device 2, the sewing heads 10 can still be moved very close to one another without mutual hindrance.
  • the pivoting of the The two tape feeders on the pair of sewing heads are then preferably in opposite directions.
  • the piston-cylinder unit 35 is triggered, which in turn actuates the braking device 34 and holds the band piece 20 'in this position.
  • the front end of the band piece 20 ' is located exactly below the hold-down device 37, which is also actuated after the actuation of the braking device 34.
  • the beginning of the band piece 20 is thus pressed onto the sewing material 5 and can then be sewn onto the sewing machine 1 after the braking device 34 has been released and the sewing machine 1 started.
  • the hold-down device 37 is also brought back into its release position. After an automatic or manual displacement of the sewing material 5 or the sewing machine 1, the process described is repeated until the sewing material 5 is occupied by the intended number of tape pieces 20 '.
