Definitions

  • the subject-matter of the invention is a method for the transport of springs for spring interiors for mattresses and upholstery according to the preamble of patent claim 1.
  • the subject-matter of the invention is furthermore an installation for the transport of springs for spring interiors and upholstery according to patent claim 6.
  • Spring interiors for mattresses and upholstery comprise usually a large number of springs with identical properties.
  • groups of springs have different spring constants which have been produced by differing hardnesses or different geometries.
  • the springs used therefore as a consequence do not in every case have exactly the same height or the same diameter.
  • the handling of springs with a different geometry i.e. a different number of widings, different diameter, different height is difficult since for grasping such a spring the transport or handling apparatus must in each case be set to the corresponding geometry. If in each case for a larger production quantity a dimension change is carried out this is still ecomonicallly acceptable. If however springs of a different geometry are required in the running production, i.e. in a single spring interior, then the conventional handling apparatus are no longer sufficient or are not in the position of processing these springs.
  • the object of the present invention is the creation of a method and an installation with which the springs with a different spring geometry and size are securely grasped and may be transported to a subsequent processing station.
  • peripherally open receivers attached on the circumference of a transport wheel designed as a transport device in taking over springs with a different length, different diameter, different number of windings and or pitch, at the exit of the spring winding machine and transfering them to a subsequent transport means, e.g. in the form of two transport belts.
  • the transfer at the spring winding machine may be effected without an additional handling apparatus singularly on account of gravity. With a higher speed or greater cycle number additionally a so-called counter- hand may support the gravity on transfer.
  • the spring may also be directly wound into the receiver at the transport wheel.
