Definitions

  • the invention relates to a sewing system with at least one lockstitch sewing machine for producing at least one seam on a material to be sewn, in particular for producing at least one dart on the material to be sewn, the sewing system being provided with a driven material transport for a specific or determinable feed direction of the material to be sewn relative to stitch forming tools which is provided for producing the at least one seam on the respective material to be sewn, the material transport having a pressure bar with which the material to be sewn can be pressed against a sewing table and the material to be sewn can be moved past the stitch-forming tools to generate a feed movement.
  • a corresponding sewing system is, for example, from WO 01/90467 A2 known.
  • darts are to be worked in by introducing at least one straight or curved seam.
  • the darts usually have the function of changing a contour of the respective item of clothing, for example, to waist a shirt or a blouse.
  • such darts represent an additional sewing process that is usually carried out separately in industrial production, i.e. independently of other sewing processes on the item of clothing.
  • sewing systems specially provided for this purpose which include a lockstitch sewing machine.
  • the items of clothing are therefore brought to the sewing system for the production of darts, processed there accordingly and then transported to a machine for subsequent further processing steps.
  • the material to be sewn is usually introduced manually into the sewing system.
  • the feed of the material to be sewn relative to the stitch-forming tools, in particular to the needle and needle bar and the gripper of the sewing machine of the sewing unit, is generated by a motor and without the need for operator intervention.
  • the material to be sewn is usually advanced to produce a darts straight.
  • the length of the feed movement required can vary.
  • the material to be sewn is often clamped onto a table top by means of a pressure bar, with the pressure bar usually being movable in the XY direction. After the end of the sewing process on the respective material to be sewn, it is picked up by a removal device and taken out of the sewing unit in the feed direction of the sewing process and deposited at a stacking point.
  • a buttonhole sewing machine which is designed as a zigzag sewing machine and the design of which is intended to enable an improved quality of buttonholes.
  • the buttonhole sewing machine has a thread cutting and clamping device for the beginning of the thread, which can be moved in the initial area of the first buttonhole bead synchronously with a presser basket in the direction of the sewing needle in order to avoid the build-up of thread tension in the area of the needle thread end held clamped.
  • a thread cutting and clamping device is provided which is fastened to a presser basket functioning as a sewing foot and has a stationary lower cutter, a pivotable upper cutter and a thread clamping plate resting on the upper cutter.
  • the The thread cutting and clamping device moves synchronously with the presser basket, whereby the thread end clamped on the needle side is kept tension-free and thus covered by the first zigzag stitches of the first buttonhole bead.
  • the end of the thread is then released from the thread cutting and clamping device by a movement of the upper knife and completely covered by the following zigzag stitches.
  • the presser basket is lifted and the thread cutting and clamping device is moved from the waiting position to the cutting position.
  • the needle thread is cut like scissors above the buttonhole and the thread end piece on the needle side is held clamped between the upper knife and the thread clamping plate.
  • the invention is therefore based on the object of creating a possibility for darts to enable a seam start with no stitch formation errors and nevertheless a short thread start, without manual post-processing being required for this.
  • the beginning of the thread cannot be pulled down under the material to be sewn during sewing, and a clean stitch pattern can also be achieved at the beginning of the seam.
  • the seam has a short beginning of the thread, which makes it unnecessary to subsequently shorten the beginning of the thread at the seam.
  • the beginning of the thread is preferably already shortened shortly after sewing and above all during the sewing process that is still being carried out, without the sewing process necessarily having to be interrupted or slowed down for this purpose.
  • the sewing unit has a switchable cutting element that can be moved in and out in an area between the clamping device and the sewing material by at least one switching operation in a feed path of the upper thread on the sewing material in order to cut through the upper thread in this area. Since in this embodiment of the invention the cutting element is only briefly in the area of the sewn material, the risk of damage to the sewn material by the cutting element can be kept as low as possible despite the cutting process in the immediate vicinity of the sewn material.
  • the cutting element can also be just a single blade with preferably only one cutting edge, which comes into contact with the upper thread as a result of being arranged in the feed path of the sewing material.
  • the feed movement of the sewing material - and thus also of the upper thread that has already been sewn - is thus used to shorten the free beginning of the thread already during the creation of the seam, without interrupting the sewing process itself and without performing a cutting movement with the cutting element.
  • this preferred embodiment of the invention no longer requires more time for the execution of the sewing process.
  • the feed movement of the sewing material is also used to generate a relative movement between the cutting element and the upper thread that leads to the cutting of the upper thread.
  • a particularly favorable development of the invention can provide that, in order to produce a dart on a sewn material that is processed later, the needle thread is severed during or after the end of the sewing process for the dart on a previously processed sewn material, the previously processed sewn material from the sewing system is removed, the pressure bar is moved back into its receiving position and the opened clamping device is arranged in such a way that the free end of the upper thread is arranged in the clamping device due to the movement and positioning of the pressure bar, the clamping device is subsequently closed and then with the start of the sewing process for the sewing material now waiting for processing is started with the clamping device still closed.
  • the upper thread can be arranged in the clamping device in a particularly quick and process-reliable manner, without a further process step or additional physical means being required for this.
  • pressure bar should also be understood to mean pressure elements that have a design other than bar-shaped in order to clamp the sewing material or press it against a worktop of the sewing unit.
  • switch-forming tools are to be understood in particular as needles and, if appropriate, the needle bars and grippers that guide them, such as are customary in lockstitch sewing machines in particular for guiding upper and lower threads.
  • the exemplary embodiment shown of a sewing system 1 according to the invention for producing darts has a sewing machine 3 arranged on a worktop 2 .
  • the sewing machine 3 is a lockstitch sewing machine.
  • Such a sewing machine is provided with stitch-forming tools, which are known per se, including above all at least one needle for an upper thread, which is arranged on a needle bar and guided by it, and a rotary hook for a lower thread.
  • stitch-forming tools which are known per se, including above all at least one needle for an upper thread, which is arranged on a needle bar and guided by it, and a rotary hook for a lower thread.
  • the stitch-forming processes using the stitch-forming tools also take place in a conventional manner known per se for lockstitch sewing machines.
  • the sewing machine 3 with its stitch-forming tools is arranged in the area of a longitudinal edge 4 of the worktop 2 and transversely to this longitudinal edge 4 .
  • a feed table 7 is located in the area of this longitudinal edge 4, starting from the corner 6 formed by the longitudinal edge 4 and a transverse edge 5 of the worktop.
  • the feed table 7 is used to receive blanks 9 and then transfer the respective blank 9 to a predetermined position on the worktop 2, from where the blank 9 is then automatically fed to the sewing process.
  • the feed table 7 can be moved toward the worktop 2 and reset again either manually or by a motor.
  • the material transfer 10 has, among other things, the function of an alignment aid for the respective blank in relation to the length of the Blank 9 in a direction transverse to the longitudinal edge 4 during the sewing process.
  • the material transfer has a drive 12 with which an angle 14 of the material transfer running parallel to the longitudinal edge 4 of the worktop 2 can be displaced parallel to this longitudinal edge 4 .
  • this drive 12 is designed as a spindle stepper motor, the rotary drive movement of which leads to a linear displacement movement of the angle 14 by means of a suitable gear, as a result of which different depth arrangements of a blank can be set.
  • This depth of adjustment can at a Control of the sewing unit 1 are preset, whereby the drive executes this input before a sewing process or a series of sewing processes.

  • the feed direction 19 can be moved in an X-Y plane parallel to the upper side of the worktop 2.
  • the feed device 11 of the exemplary embodiment is provided with a pressure bar 18 that can be moved along the feed direction 19, with which the respective material to be sewn 9 is picked up and can be moved relative to the stitch-forming tools.
  • the pressure bar 18 can thus be moved in the feed direction 19 from a first to a second end position, the sewing material being inserted and picked up in the first end position and removed in the second end position.
  • the first end position corresponds to the position of the blank which it has when the feed device 11 takes over the blank from the material take-over 10 before the feed device 11 moves in the feed direction 19 .
  • the second end position corresponds to the position of the feed device 11 or the blank 9, which this / this assumes after the end of the movement of the feed device 11 on the other side of the sewing machine 3, after the intended seam has been introduced into the sewing material 9.

During the sewing process, the pressure bar 18 moves in the direction of the second end position and in doing so guides the sewing material 9 with it and the stitch-forming tools for seam formation. In the second end position, the pressure bar 18 is located behind the sewing machine and its stitch-forming tools together with the material to be sewn.
  • a clamping device 25 is attached to the pressure bar 18 and can be moved together with the pressure bar 18 during the feed movement.
  • the clamping device 25 is arranged on the pressure bar 18 in such a way that, in relation to the X-direction of the possible feed movements, the clamping device 25 is at least approximately at the height of the sewing foot 28 located.
  • the clamping device 25 has a clamping element 26 with a flat clamping surface which can be pressed against a counter-clamping element 27 .
  • the clamping element 25 can be automatically pressed against the counter-clamping element 27 and lifted again by a drive assigned to it alone, for example an electric motor or a pneumatic drive.

  • the pressure bar 18 moves the sewing material 9 in the feed direction, in the representation of FIG figure 5 from right to left.
  • the cutting element 34 of the cutting device 33 is actuated, as a result of which it is moved from a waiting position to a cutting position. This movement is effected by a feed movement from the waiting to the separating position, which is aligned essentially parallel to the Y-direction and perpendicular to the X-direction of the feed movement of the pressure bar 18 .

  • the clamping device 25 remains closed during the retraction of the cutting element 34 and thus continues to hold the severed thread end during the further sewing process. Since the clamping device 25 is attached to the pressure bar 18, the clamping device 25, together with the pressure bar 18, also carries out its feed movement. As a result, the clamping device 25 is also guided past a suction device 37 in the course of the feed movement.
  • the controller causes the clamping device 25 to open by pivoting the clamping element 26 and, with a pulse of suction air, the suction device 37 sucks off the severed thread remnant 30b that previously covered the free end 30a of the illustrated upper thread.
