Definitions

  • the present invention relates to an apparatus for stacking flexible sheet-like products, such as for example industrial hides and similar objects, on rigid supports like trestles or pallets located downstream in the feeding line of the products.
  • a large number of apparatuses of the above mentioned type are known that essentially comprise a generally inclined surface on which the products are loaded and which defines a first movable ramp to which at least a second movable surface is associated for handling and unloading the products, said second surface serving also to provide the side of deposition of the products on the support placed downwards.
  • This apparatus is not conceived to stack properly flexible sheet-like products such as hides.
  • the international patent application WO 94/16980 discloses a stacking apparatus which is particularly adapted to stack properly hides, however it has the disadvantage of a relative complexity of the mechanism necessary to stack hides on the right side.
  • Another problem of the known stacking apparatus is the limitation to the minimum unloading height of the products that in several cases it is useful to stack on very low platforms, pallets or even on crossbars laid on the ground.
  • the platforms or the pallets were necessary to arrange the platforms or the pallets on additional supports, possibly adjustable in height to allow to start the stacking operation.
  • a principal aim of the present invention is to solve the above mentioned problems by means of an apparatus for stacking flexible sheet-like products which has a simplified construction, a reduced size, high reliability and capability of unloading the products at a minimum height.
  • an apparatus for stacking flexible sheet-like products such as industrial hides and similar objects, in accordance with claim 1.
  • an apparatus for stacking flexible sheet-like products comprises a supporting frame structure 2 formed by metallic profiles and plates supporting a first movable surface 3 for loading and move forward the products P along the direction V and a second movable transport surface 4 for handling and unloading products P on a gathering trestle C or on pallet T.
  • the movable surfaces 3, 4 are preferably made by conveyor belts or bands which continuously rotate and are tensioned by end rollers, at least one of which is driven to promote advancement of the products P. Both first and second surface 3, 4 are formed by at least two sections respectively indicated 3', 3" and 4', 4" which are mutually hinged and arranged to contact each other.
  • the second movable surface 4 is mounted on rollers 5 sliding along lateral rod-like guides 6.
  • Each guide 6 is supported by a lateral carriage 7 which is mounted on rollers 9 to move along vertical uprights 8.
  • Each lateral carriage 7 is coupled to a vertical screw 10 which is in its turn driven by an eternal motor so as to move between an upper end position, as depicted in Fig. 1 with a continuous line, and a lower end position, as depicted in Fig. 1 with a phantom line, approximately superposed to pallet T.
  • the first feeding surface 3 has a forward end 11 hinged to the carriage 7 around axis H which is substantially normal to the advancement direction V of products P, so as to overlap the second movable surface 4 even when this latter is in its fully extended forward position.
  • the backward end of the first movable surface 3 is hinged to a fixed point 12 placed forward to the tensioning rollers 13 of products P.
  • the side guides 6 of the second movable surface 4 are formed by two separate and adjacent portions indicated 6m and 6v, arranged respectively backward and forward of the articulation axis A affixed to carriage 7.
  • the backward guide portion 6v is substantially horizontal, while the forward guide portion 6m is swingable since it is supported proximate to its upward end by a roller 14 sliding along an inclined stationary guide 15 between an upper end position and a lower end position.
  • roller 14 is in its upper end position and carriage 7 is in its upper position, the guide portion 6m is substantially parallel to the first movable surface 3 and accordingly the second movable surface 4 can be displaced underneath the first movable surface 3 as is depicted in Fig. 1 with a continuous line.
  • roller 14 When roller 14 is in its lower position along guide 15 and carriage 7 is in its lower position, as depicted in Fig. 1 with a phantom line, the backward guide portion 6m is approximately horizontal and in line with the guide portion 6v.
  • a further peculiar aspect of the present invention resides in the driving mechanism of the second movable surface 4, generally indicated with the reference numeral 16.
  • Such a mechanism is essentially formed by a pair of belts or chains 17, 17', of identical shape, arrange in side-by-side relationship, mutually coupled to a common shaft and further wound on pinions 18, 19.
  • chain 17 is only designed to be driven by pinion 18, while chain 17' is designed to be coupled to section 4' of the movable surface 4 by means of clamp 20.
  • Fig. 4 further shows the structure of the articulation joint 21 between the guide portions 6v and 6m of each lateral guide 6.
