Definitions

  • the invention relates to a device for smoothing tubular stretchable material with at least one closed end, in particular for forming stockings or tights, with at least one device for loading and stretching the material on an elongated form, and with at least one device for heating the material on the mold, the device for feeding and clamping the material having a gathering device.
  • Such a device is known from GB-A-2 181 465.
  • Stockings or tights go through a dyeing process in their manufacture, which can result in shrinkage of the fabric and which at least partially results in the fabric sticking together, so that the stockings are in a crumpled form.
  • the stockings are then visually checked for defects by a light box.
  • the stockings then arrive in a conventional manner in a heating chamber, in which they are briefly heated to temperatures above the previous dyeing process, that is to say to a temperature of approximately 100 to 110 ° C. This results in relaxation on smoothing the stockings.
  • the stockings are moved from the heating chamber to a pull-off station, at which the stockings are pulled off the hangers.
  • the stockings are transferred in a conventional manner to a packaging machine in which the stockings are packed ready for sale by means of a conveyor belt or the like.
  • the conventional arrangement also has the disadvantage that the stockings are removed from the hangers while still warm and are transported to the subsequent packaging machine. This leads to post-shrinking processes and changes in shape, so that the dimensional accuracy of the stockings is impaired and a correct position in the sales packaging is not guaranteed.
  • the tights are drawn onto an elongated shape, which consists of two flat strips arranged side by side, with the aid of endless belt drives.
  • the belt drives are integrated into the flat strips such that the strands protrude laterally over the narrow end faces and thus, after putting on a pair of tights on the end of the flat strip, the tights are completely stretched onto the two adjacent flat strips by the circumferential strands.
  • U-shaped holders are inserted into the tights from the open end and moved along the lasts in order to overlap the tights from the flat lasts to the two holders and on the latter to pick up. From the two holders, the tights are then transferred to the subsequent shaping device on substantially U-shaped brackets, for which purpose the holders are moved along the brackets.
  • the invention is therefore based on the object of providing a device for smoothing tubular, stretchy material with at least one closed end, in particular for shaping stockings or tights, which largely prevents damage to the material and ensures trouble-free operation.
  • this object is achieved in a device according to the type mentioned at the outset in that the gathering device has at least one belt drive with at least one endlessly rotating belt for pre-gathering the material on the gathering device, and in that the gathering device is assigned gripping elements for taking over the pre-gathered material from the gathering device which is movable along the elongated form to apply the pre-gathered material to the form.
  • the stretchable material is therefore not clamped directly onto the mold, but is first pulled up spatially separately on a gathering device, for which purpose it only has to be placed by hand with an open end on the end of the gathering device.
  • the stretchable material is then pre-gathered on the gathering device and then taken over by the gathering device and finally stripped onto the elongated shape.
  • pre-gathering the material on the gathering device which can be carried out in a gentle manner, the material is drawn onto the elongated shape in an extremely gentle and uniform manner in the subsequent stripping process.
  • the device required for this purpose to take over the pre-gathered material from the gathering device and then to strip it onto the elongated form can have a particularly simple construction and only requires gripping elements which can take over the gathered material from the gathering device and can then be moved in the longitudinal direction along the elongated form to pick up the gathered material on them.
  • the gripping elements in the device according to the invention can at least partially be moved laterally into the gathering device and can be spread outwards against one another in order to take over the gathered material.
  • At least one gripping element is arranged such that it can be tilted with respect to the other gripping element.
  • each tiltable gripping element can be tilted against a stop element, so that the gathered material is held between the gripping element and the stop element and is only released for transfer to the mold when the gripping element is in a position parallel to the other, non-tiltable gripping element is moved.
  • the tilting element limits the tilting angle of each tiltable gripping element, so that overstretching of the material due to too much tilting and thus local spreading is avoided.
  • the gathered material is clamped between the gripping element and the stop element as soon as a tiltable gripping element strikes the stop element. This prevents premature slipping of several layers of the gathered material onto the mold during the stripping process.
  • each tiltable gripping element can be alternately tilted against the stop element and moved into a position parallel to the other gripping element, while the gripping elements are moved relative to the mold in order to grip the gathered material onto the mold starting with the closed end.
  • This periodic tilting of the gripping element relative to one another results in a particularly gentle gripping of the gathered material onto the mold. Furthermore, the material is stretched particularly evenly since irregularities are automatically compensated for by the periodic tilting.
  • the tilting frequency can be controlled as a function of the relative speed between the gripping elements and the shape. Since it is possible to work with a different relative speed depending on the material when gripping the gripping elements onto the mold, it is possible in this way to achieve a particularly uniform, gentle clamping even with different materials.
  • two outer gripping elements which have a gripper finger, are tiltably arranged on both sides of a central, essentially U-shaped gripping element, the two legs of which are designed as gripper fingers.
  • the gathered material can be stripped onto the shape in a particularly gentle manner; In addition, removal of the gathered material from the gathering device is facilitated, since the gripping elements can, for example, move laterally into corresponding recesses in the gathering device.
  • each stop element is designed as a rubber buffer.
  • the gathering device has two spaced plates, between which belt drives with endless belts are arranged, which at least partially protrude outward beyond the plates.
  • the stretchable material can be picked up in a reliable manner, without the need for a precisely defined position of the material during the previous clamping by hand onto the lower end of the gathering device.
  • the stretchable material e.g. a woman's stocking is simply pulled up with the open end of its stocking leg onto the lower end of the gathering device.
  • a short switch-on of the belt drives is sufficient to gently lift up the stocking.
  • each double belt drive each double belt drive each having two belts running in parallel, each rotating in the opposite direction to the belts of the other double belt drive.
  • This configuration results in a particularly even gathering of the material, since even material placed unevenly on the gathering device is evenly transported through the four outer strands.
  • guide strips are provided between the plates, via which the straps are partially guided outwards beyond the longitudinal end faces of the plates.
  • This measure additionally increases the frictional engagement between the material to be gathered and the belt.
  • the stretchable material is women's stockings or pantyhose, it is advantageous if the shape has at least one bow which is essentially U-shaped.
  • a carousel rotatable about its vertical axis is provided, on which a plurality of shapes are arranged, the loading and clamping device and the heating device being designed as separate stations, between which the carousel can be rotated.
  • brackets are suspended from the carousel, with their roundness pointing downward.
  • the stockings are moved back to an application station for visual inspection for defects in front of a planar light source after being stretched on the brackets, so that a visual inspection is possible while at the same time the next piece, for example the next pantyhose, is already on the brackets can be raised.
  • stirrups on the carousel are pivotably secured via a stirrup holder between an arrangement which is in alignment with one another and an arrangement which is laterally displaced from the escape.
  • the gusset is spatially spanned approximately saddle-shaped, so that the gusset is held completely under tension between the two brackets.
  • pantyhose can also be subjected to a reliable visual inspection for defects in the area of the gusset, whereas in a conventional arrangement a visual inspection is not possible because of the crumpled tissue in the area of the gusset.
  • the stirrups for pulling off the material can be pivoted parallel to one another along a longitudinal axis of the stirrups, and the pulling station has two pulling belts which can be adjusted laterally on the stirrups to pull off the stockings from the hangers.
  • a folding device for transverse folding of the material is connected downstream of the pull-off tapes.
  • the folding device for transverse folding of the material directly adjoins the pull-off tapes, a change in the position of the material in the folding device is excluded, since the material is still partially held between the pull-off tapes during the folding process. The material is still under tension while cross folding is already being initiated. This ensures a smooth layer of the material during folding and correct folding.
  • the folding device can have parallel belts for transporting the material, between which a folding slide can be inserted laterally.
  • the folding device has a wrapping sheet feed for feeding a wrapping sheet.
  • a device according to the invention is generally designated by the number 10 in FIGS. 1 and 2.
  • This device is suitable for shaping tubular, stretchable material with at least one closed end, in particular for shaping tights, but could also be used for other materials, in particular for individual stockings, since these are usually shaped in pairs and then packed.
  • the device and the method according to the invention are described below using the example of a pair of tights 100 which have two closed ends 222 or legs and an open end 221 on the waistband.
  • the device has a total of six stations through which the tights pass.

  • the tights are first pulled on the gathering devices 250 by hand at the loading station 32, then pivoted counterclockwise to the clamping station 30 and clamped on the brackets 12 with the help of the clamping device 210. After the clamping process has ended, the tights are moved back to the loading station 32 by rotating the carousel 16, where they are subjected to a visual inspection for errors in front of a planar light source 20.
