Definitions

  • the present finding concerns a device to be used for transferring leathers between two conveyor belts and for depositing them on pallets, horses and the like, according to the general part of claim 1.
  • the deformation of piled up leathers is substantial in the last depositing portion, when its end portion, detaching from the conveyor belt tends, due to the very nature of the product, to remain raised or, in the worst of cases, to roll up, thus forming depressions in the piles.
  • the most common device for trying to eliminate such a drawback comprises a fixed accompanying roller that is placed in rotation by the contact with the conveyor belt.
  • Such an embodiment has the drawback of substantial difficulty of sliding of the leather between the conveyor belt and the accompanying roller, when the leather is rigid or is not laid down properly.
  • the purpose of the present finding is that of making a device for moving leathers that eliminates such a drawback.
  • the device according to the finding comprises a small sliding band, in a closed loop, held under tension and pulled through at least two rollers, arranged parallel to each other and with the axes arranged in the transversal direction with respect to the advancing direction of the leather.
  • the two rollers are supported through a frame applied on the bearer structure of the conveyor belt and equipped with means for adjusting the portion of the rollers themselves, in particular to vary its interaxis so as to give the band the correct tension.
  • the device according to the finding is mounted on the conveyor belt so that one of the side strips of the small band is at least tangent, or more advantageously, partially wound on the final curved portion of the conveyor belt itself.
  • the advancing leather always has one of its portions able to slide in the interspace defined between the surface of the conveyor belt and the surface in the small band.
  • the small sliding band goes over the aforementioned portion of leather slightly compressing it, for which reason it exerts a function on the leather that cooperates with the dragging and, at the same time, avoids the formation on its surface of creases and depressions and prevents the lifting of the edges thereof.
  • the roller-carrying frame can be adjusted so that the curved lower portion of the small band, the one wound on the lower roller, is arranged in the immediate vicinity or directly in contact with the leather laid down for which reason, in the return stroke in the conveyor belt, the aforementioned small band, as well as making it easier to deposit, carries out a levelling action on the entire surface of the leather laid down on the pile, flattening out possible ridges or curls, which may have formed along the edges thereof.
  • the small band is advantageously made from a suitably flexible material, so as to be able to adapt to the curvature generated in the contact zone with the leather, at the end part of the conveyor belt and with antistatic properties, to avoid the sticking of the leather on the small band itself, in particular at the edges, which would thus make it impossible to deposit properly.
  • the device according to the finding, wholly indicated with 1 is applied onto the bearer structure 2 of the conveyor belt 3 of the leather 4 which, with the combined advancing movement of the conveyor belt (arrow V1) and back and forth movement of the frame (arrow V2), is deposited onto the pile 5 that forms on the pallet 6 (see fig. 1) or on the horse 7 (see fig. 5) or on a subsequent conveyor belt 8 (see fig. 6).
  • the device 1 comprises a small band 10, shaped like a closed loop sleeve, which is wound on two rollers 11 and 12 with horizontal and parallel axes.
  • the inner strip 13 of the small band 10 is placed in contact with a narrow zone 14 of the leather 4, so that the sleeve takes up a variable geometry, which is configured like an arc of circle defined by the radius of curvature of the return cylinder 15 of the conveyor belt 3, for which reason there is a compression force in said zone, which constitutes the characterising element of the finding since, as well as easing the advance of the aforementioned leather, it generates a flattening action on the surface thereof.
  • the two rollers 11 and 12 are mounted on a frame, wholly indicated with reference numeral 20, consisting of two arms 21, hinged on the pin 22, coaxial with the rotation axis of the aforementioned return cylinder 15.
  • Each of the two rollers 11 and 12 is mounted on the respective arm 21 through a threaded rod adjustment member 23, by acting on which it is thus possible to vary the interaxis "L" between the two rollers, which thus act as takeup pulleys to adjust the tension of the entire sleeve.
  • the advancing direction of the small band 10 (arrow V3), matching the advancing direction of the leather 4, can occur by simple dragging, when it is placed in contact with the aforementioned leather, or else through the motorisation of one of the two takeup pulleys 11 or 12.
  • the device according to the finding is arranged so that the lower roller 12 is positioned close to the depositing surface of the leather on the pile, so that the flattening action of the small band 10 is also applied on the portion of leather 4' that gradually deposits onto the pile itself.
