Definitions

  • the invention relates to a method for closing a sewing material holder and a sewing material holder for an automatic sewing machine, by means of which the closing method can be used.
  • Sewing material holder itself has long been known and is disclosed, for example, in DE-A 35 46 238, FR.A. 2378464 and US.A.4 002 129.
  • the workpieces to be sewn together are placed in the sewing material holder, fixed in position by clamping and then sewn together.
  • the known sewing material holders usually consist of a thin bottom plate and top plate that can be folded like a lid. After closing the sewing material holder, the sewing material parts to be sewn together are clamped between the two plates. Recesses are made in both the top plate and the bottom plate, which correspond to the seam course to be produced.
  • Sewing material holders are conceivable in which the top plate cannot be swung onto the bottom plate, but can be lowered in a straight line.
  • these would have the disadvantage that the lower plate would no longer be properly visible to the operator or would no longer be easily accessible due to the necessary guide rods, which would make placing and aligning the sewing material parts significantly more difficult.
  • the invention is therefore based on the object of specifying a method for closing a workpiece holder, with which it is ensured that the once aligned workpiece parts are not displaced during clamping and to provide a workpiece holder with which this method can be implemented.
  • Fig. 1 shows an automatic sewing machine in perspective, on which one or two sewing material holders according to the invention can be used.
  • a sewing machine is described in detail in DE-A 35 46 238 and US-A 4 696 242 in terms of its structure and mode of operation, so that these documents are made the subject of the disclosure content of the following description.
  • a recess 10 is provided in the worktop 1, in which at least one sewing material holder 2 can be accommodated.
  • the material holder 2 is formed from a lower plate 3 and an upper plate 4.
  • the lower plate 3 of the material holder 2 is immovably mounted in the recess 10, while the upper plate 4 is attached to the worktop 1 via joints 11 and 11a and in Direction of the lower plate 3 is pivotable.
  • the design of the lower plate 3 according to the device is known from the above publications and is therefore not to be explained in more detail.
  • the upper plate 4 of the workpiece holder 2 outlined in FIGS. 2 and 3 consists of the frame 5 and the Pressure plate 6.
  • the pressure plate 6 is connected to the frame 5 via four lifting cylinders 7, 7a, 7b, 7c, which can be operated pneumatically, for example.
  • the lifting cylinders 7 to 7c are fastened to the frame 5 and their piston rods 8 are guided through bores provided therein and anchored to the pressure plate 6 via connecting pieces 9.
  • the lifting cylinders 7 to 7c are preferably double-acting cylinders, in which the piston rod 8 extends or retracts depending on the direction of the pressurization. As illustrated in FIG. 4, the pressure plate 6 can be raised or lowered from the frame 5 via the lifting cylinders 7 to 7c.
  • the pressure plate 6 is arranged below the frame 5.
  • 6 centering pins 12 are attached to the pressure plate and engage in corresponding centering holes in the frame 5.
  • Hinges 11, 11a are arranged on the side of the frame 5 opposite the pressure plate 6, which is formed by four angle profiles.
  • the L-shaped angle profiles form the frame 5 such that its side facing the pressure plate 6 is flat.
  • the hinges 11, 11a are formed by three levers 15, 16, 17.
  • the lever 15 is fixed to the frame 5.
  • the lever 16 is connected to the lever 15 via the joint 18 and screwed to the lever 17 at the point 19.
  • the lever 17 is fixed on the worktop 1 by means of screws 14.
  • the levers 15, 16, 17 are each symmetrical in this way trained that cylinders 20 can be articulated between them; that is, the lever arrangement shown in one dimension in FIG. 4 is again present on the other side of the cylinder 20 — not visible here (see FIG. 2).
  • the hinges 11, 11a are controlled via cylinders 20 which can be actuated by external power. These cylinders 20 are preferably also pneumatic lifting cylinders. Each cylinder 20 is articulated with its housing 21, for example via an eye 23, on the lever 17 and with its piston rod 22 on the lever 15.
  • Fig. 3 shows schematically the arrangement of the hinge 11 on the frame 5.
  • the piston rod 22 of the cylinder 20 is fully extended, the upper plate 4 is consequently shown in its lowered position.
  • the upper plate 4 pivots around the hinge point 18 in the direction of the arrow S, so that the upper plate 4 is pivoted away from the lower plate 3 .
  • the cylinders 7a to 7c are retracted so that the pressure plate 6 is as close as possible to the frame 5.
  • the hinges 11, 11a are designed in such a way that a pivoting movement of at least 45 ° is possible, the operator can view the lower plate 3 of the material holder 2 unhindered and align the material parts when the upper plate 4 is completely in its position swiveled away position.
  • the cylinders 20 are actuated so that the piston rod 22 extends and the upper plate 4 is pivoted so far in the direction of the lower plate 3 until the pressure plate 6 is in a plane parallel to this.
  • the lifting cylinders 7-7c are then activated, ie extended.
  • the pressure plate 6 is lowered vertically relative to the frame (or more importantly, relative to the lower plate 3) (arrow A), namely until the sewing material parts are clamped between the plates 6, 3.
  • the automatic sewing machine is computer-controlled.
  • the person skilled in the art will readily be able to have the control of the closing process also carried out by the computer, so that a completely automated process occurs after the sewing material has been aligned. Due to the fact that the pressure plate 6 comes to rest on the lower plate 3 in a straight line movement, the sewing material parts are immediately clamped over a large area, so that slipping during clamping is reliably ruled out.
  • such sewing material holders can also be designed in such a way that a plurality of sewing material parts lying one on top of the other are positioned and clamped together and overall.
  • the material holder can also have further plates arranged on the hinges 11, 11a between the lower and the upper plate 3, 4.
