Definitions

  • the invention relates to a device for shaping stockings or tights of the type specified in the preamble of claim 1.
  • Devices of this type are required to stretch and iron unshaped stockings and tights and to shape them in their entire length ready for packaging.
  • a molding is required for stockings and two molding strips arranged one behind the other or offset from one another are required for tights.
  • belt drives are arranged on the two longitudinal sides of the molding strips, each of which has belts which run in opposite directions and are guided within the strip contour. The direction of rotation of the belt drives is chosen so that the outer strands move upwards in the pull-up position and downwards in the pull-off position. The operator only needs to pull the stocking or tights to be molded over the lower end of the last.
  • the moldings are pivoted about an overhead horizontal axis for the entry of a transport and ironing device consisting of heated endless belts.
  • a transport and ironing device consisting of heated endless belts.
  • Form and discharge plates arranged on the lasts push downwards and form the top of the stocking or pantyhose.
  • the rollers of the strap are closed and thus fix the position of the stocking or pantyhose tip, the subsequent pulling process being supported by the change in the running direction of the belts.
  • the strips swivel back into their starting position and are ready for another pulling up process.
  • insert sheets For a better presentation in the packaging, it is often desirable to arrange insert sheets in one of the stockings or pantyhose legs. This applies in particular to patterned goods, the pattern of which can only be recognized through the contrasting effect of the insert sheet through a packaging window.
  • the invention is therefore based on the object of improving the known molding device of the type mentioned in such a way that a semi-automatic or automatic insertion of insert sheets into the stockings or tights is made possible in the course of the molding process.
  • the invention is based on the idea that a holding device is to be arranged on a broad side of the last within the last contour, which can be loaded from the outside with an insert sheet before each opening operation, which comes into the inside of the stocking or pantyhose when opening and is then pulled off together with the stocking or tights.
  • the holding device contains two mutually facing, open to the loading side, aligned in the longitudinal direction of the bar, overlapping the longitudinal side edges of the insert sheet and at least one end stop arranged at the end of the guide rails and detachable during the removal process for the front sheet edge.
  • the transfer mechanism arranged in the region of the holding device expediently contains an ejection slider which can be controlled during the pulling-off process and is displaceable at a speed corresponding to the pulling-off speed and which abuts against the rear edge of the sheet in the ejection direction.
  • the insert sheets are advantageously inserted from above at an acute angle into the essentially vertically oriented holding device in free fall.
  • the insertion is conveniently carried out automatically with the aid of a suitable sheet dispenser.
  • the sheet dispensing device has a stacking magazine for the insert sheets and a conveyor device which can be successively loaded with the insert sheets from the stacking magazine via a separator and which opens into the holding device of the bar at an acute angle.
  • the molding machine shown in the drawing is intended for the shaping of tights. It contains two substantially vertically oriented, elongated flat strips 10, 12, which are arranged on a frame 14 about a transverse axis arranged in their upper region from a pull-up position to a pull-off position and pivotable relative to one another.
  • a motor-driven belt drive 16, 18 extends over each longitudinal side of the strips 10, 12, each of which has a pair of belts 16 ′, 18 ′, which is guided above and below via pulleys 20.
  • the pulleys 20 are arranged in the strip so that only one strand of each belt protrudes from the strip so that the contour of this strand limits the contour of the strip 10, 12 on the long sides.
  • the Belt drives 16, 18 are motor-driven in such a way that the two pairs of belts 16 ', 18' run counter to one another at the same speed.
  • the direction of rotation is chosen so that the outer strands move upwards in the open position and downwards in the open position.
  • a shaping and ejecting plate 22 which can be moved along the lasts on the back of the lasts and which is not removed during the pulling-off process, taking the tips of the toes and handing them over to one shown smoothing roller pair can be pushed forward beyond the lower strip end 24.
  • the front bar 10 additionally contains a holding device 26 for insert sheets 28, which can be loaded via a sheet dispenser 30 arranged laterally next to the bars on the machine frame 14. Relatively stiff cardboard and plastic die-cuts are preferably used as insert sheets 28.
  • the holding device 26 contains two opposite guide rails 32, 34 on the broad side of the relevant strip 10 for receiving the longitudinal side edges of the insert sheet 28 and an end stop consisting of two cams 40 which pass through openings 36 in the broad side cover 38.
  • the insert blades 28 are inserted into the guide rails 32, 34 from above at an acute angle a and fall downward therein until they strike the cams 40 with their end edge 28 '.
  • the stop cams 40 are arranged at one end of a two-armed lever 44 pivotally mounted within the bar 10 about a transverse axis 42 so that they are retracted against the force of the spring 46 into the interior of the bar when the lever 44 is pivoted and the end stop for the purpose of ejecting the Release insert sheets.
  • the lever is actuated with the aid of a wedge-shaped control curve 48 on a control rod 50 which can be displaced along the bar.
  • a control rod 50 which can be displaced along the bar.
  • an ejection slide 52 which can be actuated together with the control rod and which, during the pull-off process, has its leading edge 54 against the rear Edge 28 "of the insert sheet 28 strikes and ejects it from the holding device 26.
  • the movement sequences of the stocking ejection plates 22, the control rod 50 and the sheet ejection slide 52 can be coordinated with one another in the pulling-off process, for example, via a control curve (not shown) of a program work in such a way that the insert sheet 28 is pulled off at a designated, always constant place within the one leg of the pantyhose with the pantyhose.
  • the sheet dispensing device 30 arranged laterally next to the strips 10, 12 on the machine frame 14 essentially consists of a stacking magazine 56, a conveyor device 58 consisting of an endless conveyor and a suction device 62 which can be swiveled back and forth about a horizontal axis 60 for the individual removal of sheets 28 from the stacking magazine 56 and transfer to the conveyor 58.
  • the sheets 28 are transferred in an orientation standing on their one longitudinal side edge 28 "to the input point 64 of a horizontal conveyor path 66 of the conveyor 58 and from there they are also conveyed by a driver cam 68 arranged on the endless conveyor designed as a chain brought to the waiting position 70 still on the horizontal conveying path 66.
  • the horizontal conveying path 66 merges in the conveying direction into an ejection path 72 pointing downward by approximately 90 ° , which comes into the insertion point of the holding device 26 at an acute angle the bar opens.
  • the lower end of the ejection section 72 is at a small distance from the last 10, so that there is a free space for the tights to be pulled on.
  • the sheet 28 in the waiting position 70 is conveyed to the holding device 26 via the ejection path 72 in the following work step. The transfer of the sheet 28 takes place in free fall. In order to ensure reliable sheet transfer, the sheet is brought to a sufficient ejection speed by the driver cam 68 at the ejection point.
  • the suction device 62 and the endless conveyor are driven by a common motor 74, so that coordinated movements are guaranteed.
  • the step-by-step triggering of the motor 74 or the brake / clutch combination 78 connected to it takes place in a centrally controlled manner via the control unit (not shown) of the puller and puller. It is thereby achieved that a new insert card 28 always arrives in the holding device 26 when the pair of lasts 10, 12 is pivoted back into the pull-up position after the pull-off operation and is ready to pull on a new pair of tights.
