Definitions

  • the invention relates to a device for transferring a piping strip from a preparation station to a sewing material part lying on the table of a sewing machine, comprising a stationary support plate for the piping strip and a piping receiver having a molding rail and a gripping device, which is between a piping receiving position in which it is connected to the molding rail is lowered onto the support plate, and a piping delivery position is adjustable.
  • a device of the type mentioned above is known for example from German utility model 75 25 743.
  • the piping strip provided on the support plate is placed on the workpiece by the piping sensor, folded around the shaping rail and then sewn onto the workpiece with a two-needle sewing machine.
  • a pocket incision is made between the two seams using a rotating knife.
  • a wedge-shaped gusset cut is made at the ends of the pocket incision.
  • the piping strip has been sewn on, its longitudinal ends and edges parallel to the seams are folded through the pocket incision on the left side of the sewing material part, so that only the piped pocket opening can be seen on the outside of the sewing material part.
  • the invention has for its object to provide a device of the type mentioned, which makes it possible to save this additional operation after sewing the piping strips.
  • a groove or slot-shaped recess running parallel to its longitudinal direction is formed in the underside of the shaped rail facing the support plate and that a cutting device with at least one knife is arranged on the support plate such that the knife during the cutting process in engages the recess in the shaped rail of the piping pickup located in its receiving position.
  • the device according to the invention cut a piping strip at its longitudinal ends before it is folded and sewn onto the sewing material part.
  • the cutting takes place after the piping pick-up has been placed on the piping strip, so that the position of the piping strip relative to the piping pick-up can no longer change after the cuts have been made at the longitudinal ends of the piping strip.
  • This ensures that the incisions at the longitudinal ends of the piping strip are exactly in line with the later pocket incision and thus in the middle between the seams to be produced.
  • Cutting the piping strips before they are grasped by the piping pickup would lead to problems that are difficult to solve in practice.
  • the piping strip would then have to be aligned in a very specific position relative to the piping pickup located in the receiving position in order to ensure that the seams and the pocket incision have the desired position relative to the longitudinal incisions of the piping strip already present.
  • the cutting device preferably has two counter-adjustable knives, which, for example, can each be mounted on a slide adjustable below the support plate parallel to the longitudinal direction of the shaped rail and protrude through a slot in the support plate.
  • the carriage can be adjusted by a spindle drive or by a pressure cylinder operated by a pressure medium.
  • the knives are preferably formed by rotating disk knives, each of which is driven by a motor arranged on the carriage.
  • a frame 14 is articulated about a pivot axis 16 above a sewing machine table 10 on a table 12 that is fixed to the table or sewing machine.
  • the piston rod 18 engages a pressure-actuated working cylinder 20, which in turn is articulated on the table-fixed frame 12 and by means of which the swivel frame 14 can be adjusted about the swivel axis 16.
  • a piping receiver In the swivel frame 14, a piping receiver, generally designated 24, is guided vertically displaceably by means of two guide rods 22 lying one behind the other in the direction of view of FIG. 1.
  • the actual piping pickup 24 comprises, as shown in FIG. 2, a C-shaped bracket 32 connected to the intermediate piece 30, on the free ends of which a flat central rail 34 is fastened.
  • a shaped rail 36 is fastened, which lies in a plane perpendicular to the plane of the center rail and is bent open at one free end in the manner shown.
  • the central rail 34 and the shaped rail 36 together form an upside-down T-profile, as can be seen in FIG. 1.
  • the needle carriers 38 and 40 Arranged on both sides of the middle rail 34 are two plate-shaped needle carriers 38 and 40, each of which has gripper needles 42, 44 directed at its lower longitudinal edge inclined to the surface of the shaped rail 36, the inclination of the gripper needles 42 of the needle carriers 38 being opposite to the inclination of the gripper needles 44 the needle carrier 40.
  • the needle carriers 38 and 40 arranged on both sides of the central rail 34 are each connected in pairs by pins 46 and 48 which are each guided in elongated holes 50 and 52 in the central rail 34.
  • the longitudinal axis of the elongated holes 50 and 52 is directed parallel to the hook needles 42 and 44, respectively.
  • Each of the needle carriers 38 is articulated via an extension 54 to the piston rod 56 of a working cylinder 58, which in turn is articulated on extensions 60 of the needle carrier 40.
  • a tension spring 62 is tensioned, which normally moves the needle carriers 38 and 40 towards each other, whereby they are held in their upper position due to the oblique elongated holes 50 and 52, respectively, in which the gripper needles 42 are above the shaping rail 36 are located.
  • the working cylinder 58 is pressurized with pressure medium, the needle carriers 38 and 40 are pressed apart, and due to the guidance in the oblique elongated holes 50 and 52 they are simultaneously moved in the direction of the shaped rail 36.
  • the gripper needles 42 emerge from the bottom of the shaped rail 36 through slots, not shown. so that they can penetrate into a piping strip lying below the shaped rail 36.
  • the piping sensor described so far is known per se and works as follows:
  • a piping strip 66 is laid out by hand in relation to the sewing machine table 10 inclined support plate 64 and aligned with the aid of a stop bar 68 of the support plate 64.
  • the piping receiver 24 is moved vertically upwards with the aid of the working cylinder 26 in FIG. 1.
  • the swivel frame 14 is swiveled to the left by the working cylinder 20 in FIG. 1, so that the piping pickup 24 is located above the support plate 64 in the position indicated by dashed lines.
  • the piping pickup 24 is lowered by the working cylinder 26 with the shaping rail 36 onto the piping strip 66 and the piping strip 66 is gripped with the aid of the gripper needles 42, 44 in the manner described above.
  • the piping strip 66 is inserted between the two legs of a schematically indicated cloth clamp 70, which holds a workpiece 72 on the sewing machine table 10. With the help of folding elements (not shown), the piping strip 66 is then folded around the shaped rail 36 in the manner shown in FIG. 1, so that it rests on the middle rail 34 with its two edge sections. The piping strip is held in the folded position by means of clamping elements on the cloth clip 70, which are also not shown and are sewn onto the material part 72 by means of a two-needle sewing machine after the piping receiver 24 has been pulled out, with a longitudinal section parallel to the seams 74 (FIG.
  • 64 are below the support plate
  • Two rotating knives 86 are arranged, each of which reach through a slot 88 in the support plate.
  • the slots 88 are aligned with one another and with the central rail 34 of the piping receiver 24 when the latter is in its receiving position on the support plate 66.
  • the disk knives 86 are each driven by a motor 92, which is arranged on a carriage 94, preferably in such a way that it can be adjusted in a direction not shown in the direction of the double arrow A perpendicular to the support plate 64.
  • the slides 94 are each guided on a guide rod 96 running parallel to the support plate 64 and a threaded spindle 98 parallel to the latter, which can be driven by a motor 100 and by means of which the slide 94 can be adjusted in the direction of the double arrow B parallel to the support plate 64.
  • the guide rod 96, the threaded spindle 98 and the motor 100 are each fastened in a suitable manner to the underside of the support plate 64.
  • the two motors 100 are expediently controlled in such a way that the two disk knives 86 can be adjusted in opposite directions to one another.
  • the piping strip 66 is placed on the support plate 64 so that it abuts the stop bar 68 with one of its longitudinal edges. Then the piping receiver 24 is placed on the piping strip 66. This is grasped with the aid of the gripper pins 42, 44 and clamped and held on the support plate 64. The end sections 80 of the piping strip are then cut along the cutting lines 82 (FIG. 3) by adjusting the driven disc knives 86 in the direction of arrow B. The piping strip 66 cut in this way no longer changes its position relative to the piping receiver 24 and is now further processed in the manner known per se.
  • the cutting device according to the invention is not limited to the use of the disc knife. There are also z. B. reciprocating knife blades can be used.
