Definitions

  • the present invention relates to a method for automatic orientation of hosiery articles such as socks or the like with respect to a predetermined plane.
  • the invention relates to a device that carries out this method.
  • an optical sensor detects the protrusion of the foot and stops immediately the rotation leaving the sock in the predetermined angular position.
  • Such a device even if it is technically effective, causes a high energy consumption due to the introduction of the air flow, and furthermore a difference in the flow rate of air is required depending upon the type of knitting quality of the socks.
  • US 5904279 concerns a method and an apparatus for straightening substantially tubular textile goods, such as socks, stockings, tights etc., which have an asymmetry, such as a reciprocated heel.
  • the textile goods are drawn onto a substantially cylindrical form, the form with the textile product drawn onto it is rotated about a longitudinal axis, during rotation the asymmetry position is detected as is the position of the form and finally the form is rotated into a predetermined position corresponding to the detected asymmetry position. Simultaneously the stitch pattern of the textile product drawn onto the form is inspected for faults and flaws.
  • a process of orientation of socks begins with the picking up the same from a special container. These are put automatically or manually in a random way on substantially cylindrical elongated supports, i.e. without taking care of their orientation.
  • the elongated support has at least one cylindrical portion.
  • the sock even if stretched elastically in order to match the shape of the support, has a protrusion oriented towards outside at the heel.
  • the rotation is effected of the sock same with respect to the axis of the support, in order to detect the protrusion of the heel according to a tangential longitudinal direction, by using optical sensors.
  • the axial rotation on the support can be carried out in one of the two ways described below:
  • the mechanism of rotation stops automatically and the angular predetermined position of the sock is thus determined.
  • the sock is withdrawn oriented from the support.
  • the presence of the sock on the elongated support for orientation purposes is associated to steps of qualitative control of the same by an operator.
  • the integral rotation of the support and of the sock is provided, according to an angle of at least 180°, so that the operator can see all its surface without moving or using mirrors.
  • a sock provides differently knitted zones and precisely: a foot 1a, a heel 1b, the leg 1c and a leg collar 1d.
  • Such zones have different functions and precisely the foot 1a is thickly knitted, heel 1b is thickly knitted and curved, the leg 1c has a tubular knitting, often with pattern, and the leg collar 1d is a tubular collar knitted with elastic thread.
  • Such zones have been shown with different graphical background.
  • a knee sock 2, or tubular sock, instead, as shown in figure 2, has a tubular knitting with at the end a closure seam 2a.
  • the foot is not knitted but is shaped when steaming the knee sock on forms.
  • elongated support 3 For orienting sock 1 or knee sock 2 it is possible, putting them on an elongated support 3 (figure 3).
  • the elongated support 3 notwithstanding shown of plain cylindrical shape , can have also grooves or oval or rectangular with rounded edges shape.
  • sock 1 or of knee sock 2 For automatic orientation of sock 1 or of knee sock 2, they can be put random on support 3 (figure 4A or 5A) and then a rotation about its own axis is given to the support.
  • heel 1b is visible since it has a slight but relevant protrusion.
  • heel 1b has a curved profile with a central vertex
  • optical sensor 4 can detect this vertex calculating an average of the measured values, with possibility of sufficient precision for detecting the plane of orientation, indicated by a dotted/dashed line in figure 6.
  • a plurality of sensors 4 or 5 can be provided, for example two, three or four angularly spaced sensors.
  • a control software is provided which, according to the sensor that detects heel 1b or seam 2a, causes a further rotation to the sock up to the orientated position.
  • an array of optical sensors can be provided, for example CCD or equivalent, which provides a matrix of signals of presence of the heel or of the seam.
  • the sensors detect the shape of the sock from the above.
  • they detect a line having a greater density, i.e. the seam.
  • mechanical sensors can be provided having tracing points capable of giving signals of presence when are touched by the heel or when they feel a higher thickness of the seam.
  • the rotation of the sock may be carried out by means of axial integral rotation of support 3 with sock 1 on a support base. Otherwise, as shown in figure 6, the rotation of the sock can be carried out by means of counter rotating movement of rollers 6, 6' tangential to the support that is kept still.
  • the elongated support 3 is as smooth as possible, whereas the rollers 6, 6' are coated by a friction surface, so that a relative movement of circumferentially tangential rotation is created between sock and support.
  • Support 3 can be a carrier in a production cycle. In fact, the sock must follow a path that comprises various work stations. In particular, with reference to figure 7, the following steps are carried out:
