Definitions

  • the present invention relates to a conveyor device tor shoes (i.e. footwear), provided with sole and/or insole, in an apparatus for thermal treatment, and also to an apparatus for thermal treatment of shoes provided with said conveyor device.

  • shoe is intended not only as the finished shoe ready for packaging and sale, but also as any semi-finished product which is to become a shoe.
  • the term “shoe” is also intended as the semi-finished product constituted of the upper (i.e. shoeupper) with only; the insole, or of the
  • the treatment to stretch the leather is particularly critical; this consists in treating the upper, optionally assembled only with the insole, at high temperature, either dry or with steam.
  • the shoe not yet finished, is positioned on a conveyor device which conveys it into a specific oven inside which, in predefined conditions of relative humidity and temperature, (up to 200 0 C) the shoe dwells for sufficient time to perform said operation to stretch the leather.
  • the unfinished shoe mounted on a relative last and usually constituted only of the upper to which the insole has been bonded (e.g. glued), is conveyed by the conveyor device, into and out of the chamber of the oven, preferably so that during thermal treatment the upper does not come into contact with any bodies other than the insole, such as the walls of the oven or of the conveyor device itself, so that stretching of the leather of the upper is not endangered.
  • the temperature, any delivery of steam and the dwell time of the shoes in the chamber of the oven are parameters that are carefully regulated, as any steam present, the heat transmitted by convection and irradiation inside the chamber of the oven and, above all, the heat transferred by conduction from the conveyor device to the shoe, can easily cause reactivation of the adhesive used to assemble the insole with the upper, with consequent undue detachment of the two parts.
  • Another critical thermal treatment to which shoes can be subjected consists in the placing said shoes in a chamber in which conditions of low temperature are maintained (known as "refrigeration chamber"). This treatment allows complete deactivation of the adhesives used to assemble the soles and also stabilizes the entire shoe.
  • the shoes are placed on a supporting element which, kinematically connected to motor means, conveys the shoes into the refrigeration chamber, allows them to dwell there for a predetermined period of time, and then conveys the shoes out of the refrigeration chamber.
  • this is constituted of a common conveyor belt, usually made of metal, on the links of which the lower portion of the shoe, that is the insole, the arch support or the sole, of according to the degree of assembly reached, is simply placed.
  • the conveyor belt unavoidably at a low linear speed, performs the operations to convey the shoes into the apparatus for thermal treatment, to allow them to dwell there for the required time and to convey them out of the apparatus.

  • EP-A-0.512.127 refers to the use of a conveyor belt to convey shoes into an apparatus for thermal treatment. Mere placing of the shoe on the conveyor belt, usually made of metal, does not obviously provide sufficient guarantee that the shoe will not overturn during movement on said belt or will not sway (i.e. swing) thereby allowing the upper, or other outer portions of the shoe, to come into contact with damaging foreign bodies.
  • shaped moving supporting elements can also be provided which, made integral or obtained in once piece with said conveyor belt, allow the shoes to be constrained mechanically, preferably by interlocking (thanks to matching shapes).
  • United States patent US 4.553.341 refers to the use of a conveyor belt provided with shaped seats inside which shoes can be inserted to undergo treatment in an apparatus for thermal treatment.
  • the aforesaid seats are constituted of openings of suitable dimension and shape, into which an upper can be only partially inserted, so that it is constrained on the conveyor belt.

  • the means to hold the bottom portion of the shoe can be of the magnetic type, for example, exploiting the presence of the last inside the unfinished shoe.
  • magnetic or ferromagnetic elements can be inserted in the last of the shoe in correspondence to the sole, arch support or insole, and corresponding ferromagnetic or magnetic elements can be positioned on the insulating support to functionally engage with the elements present in the last.
