Definitions

  • the present invention relates to an apparatus and to a method for transferring items substantially flat and flexible, particularly skins.
  • the animals skins must be loaded on and unloaded from aerial transfer means from which they are hanging in order to be transferred from a working station to a next working station, during the working process.
  • the aerial transferring means generally includes hanging drive means fixed to ceiling and comprising a conveyor chain supporting a plurality of rods which extend from it substantially horizontally and from which the elements of skins are hanging.
  • Each rod shows a "C" shape bent axis which defines a portion of the lower rod working as support member for a respective skin element.
  • WO 97/48630 discloses a system for transferring skins where a telescopic arm, horizontally extending, is sliding in vertical direction on a respective support column.
  • the telescopic arm can move between each rod of the aerial transferring means and a ground conveyor lying by side of the aerial transferring means so as to move the skins from the interested rod to the conveyor, or vice versa.
  • WO 97/48630 illustrates furthermore a support frame having portal shape which extends above the aerial transferring means and is provided with support rods, suitable to be operated by end pliers in order to carry out transferring of the skins from the aerial transfer means to a ground conveyor, or vice versa. Also this portal frame involves considerable encumbrance.
  • FR 2636611 discloses an apparatus for handling and transferring plane and flexible products, in particular hides and leathers, between two workstations comprising a carrying structure intended to be interposed between the said stations, a shaping transporter arranged between the structure and one of the stations, a transfer gantry crane mounted so as to move between the second station and the transporter and at least one head for gripping by suction the flexible products, said head being suspended so as to move relative to the gantry crane.
  • FR 1602174 discloses a method and an apparatus for transferring plane and flexible sheets, especially leather, from a storage position to a conveyor wherein the sheets are first placed on a movable surface while maintaining such surface in a substantially vertical position and then tilting the surface toward said conveyor.
  • the apparatus for performing the method comprises a movable, tiltable surface supported on a frame and suction means movable back and forth between a sheet storage position and a position above the frame, said surface comprising at least one endless belt or a series of rollers actively driven, and rollers being rotatably supported on shafts rigidly connected to each other and one of the shaft being operatively connected to tilting means which tilt the movable surface constituted by said belt or rollers back and forth though a tilting angle to direct the sheet toward said conveyor.
  • An object of the invention is to improve the existing systems for the movement of the skins, particularly in order to make available the reduction of the encumbrances.
  • an apparatus for transferring items substantially flat and flexible, comprising first conveyor means of said items, second conveyor means of said items, transfer means for transferring said items from said first conveyor means to said second conveyor means, or vice versa, support means for said transfer means, characterized in that said support means are movable between a working position at said first conveyor means and a further working position at said second conveyor means, or vice versa.
  • an apparatus 1 includes a base 2 moving between lower conveyor means 3 of skins and upper conveyor means 5 of skins.
  • the upper conveyor means 5 includes cantilever rod means 6 which extends substantially horizontally from chain means, not shown, and is hold in place by clamp means 9 supported by a column 10.
  • the movable base 2 includes a plate 11 to which first drive columns 12 are fixed on which members 13 of a first vertically sliding frame 14 are externally slidably engaged.
  • a second frame 15 is engaged to slide in a vertical direction with respective further members 17 on external slide ways 16 of the first frame 14.
  • An operating pneumatic cylinder 19 extends between the base 2 and a cross-bar 18 of the first frame 14, which drives and controls the vertical displacements of the first frame 14.
  • a further pneumatic cylinder 20 extends between the cross-bar 18 and a further cross-bar 21 interconnecting upward the further members 17 and controls the vertical displacements of the second frame 15.
  • the further cross-bar 21 includes a "U" shaped portion such to surround over three sides the rod means 6, so as to be able to receive on the own upper borders a region of a skin element 4 initially placed crossover the rod 6.
  • the lower conveyor means 3 includes a conveyor 24 and a set of rollers 25 arranged so as to cause a skin element 4 to rise along the direction shown by the arrow F1 toward an intermediate conveyor 26.
  • the intermediate conveyor 26 is horizontally movable by means of an operating cylinder 27 in order to define a space S large enough to allow the frames 14 and 15 to pass through it when the moving base 2 lies below a skin element 4 which is in a transferring position wherein it is partially placed on the intermediate conveyor 26 and partially placed on the rollers 25.
  • the plate 11 is downward provided with wheels 28 with vertical axis laterally engaged in slide ways 29 of a block 30.
  • a rack 31 is provided, fixed to the block 30 and engaged by a pinion 32 of a motor-reducer 33 mounted on the moving base 3.
  • the second frame 15 is provided with divaricating means 34 comprising a couple of column 35 extending parallel to the further members 17 and externally to them in order to support a couple of upper wings 38 swinging about horizontal axes and a couple of lower wings 37, both the lower wings and the upper wings being hinged in a swinging manner to a rod 37a interconnecting the drive columns 35.
  • Operating means 39 is arranged in order to wide open apart the upper wings 38 through lever means 41 from an opening position shown in Figure 6 to a closing position shown by dashed line in Figure 8.
  • Further operating means 36 is provided in order to produce, by means of further lever means 43, an angular rotation of the lower wings 37 from a closing position shown in Figure 6 to an opening position shown by dashed line in Figure 8.
  • the wide opening apart of the upper wings 38 is used to aid the separation of a skin element 4 from the rod 6 from which it is initially hanging so as to make possible that the skin element 4 is first detached from the rod 6 and then unthreaded from it is a longitudinal direction.
  • Divatication of the couple of lower wings 37 is instead used to move away each from the other the borders of the skin element 4 when the skin element 4 is on board of the second frame 15 and assures that the above mentioned borders are spaced between them by an amount greater than the distance S, so as one border is received by the intermediate conveyor 26 and the other is received by the rollers 25.
  • an apparatus 60 for transferring skins initially coming from a conveyor 24 and then transferred from here onto an upper conveyor 49 having a proximal end connected to the conveyor 24 and a distal end ending above a lower conveyor 46 overhanging a building region of a skins stack 45.
  • the conveyor 49 shows its own distal end hinged around a fix axis and can accomplish an circular arc R being joint to slide way means 48 moving on vertical drive means 50.
  • Transversal drive means 47 is further joint to the vertical drive means 50 onto which a lower conveyor 46 is mounted moving between an extended position Z where it overhangs the region of the stack 45 in order to start to lay thereupon a skin element 4 and a withdrawn position Y where the lower conveyor lies substantially outwards the encumbrance of the stack region 45.
  • sucker type clamp means 52 is provided that may be raised by a pneumatic cylinder 51 supported by a frame 53.
  • the clamp means 52 is suitable to operate on a border region of a skin element 4 of a stack 45 by rising it for an amount sufficient to allow belt conveyor means 54 to slip under the skin element partially risen and take it progressively in charge on itself.
  • the convyer 54 is then moved away from the stack region 45 along the direction shown by the arrow F2 on horizontal drive means 54a up when it reaches a position near a transit carrier 55 which delivers the skin element 4 in advance transferred to him by the conveyor 54 to the conveyor 24 in order to move it towards another working station.
  • an apparatus C in a manufacturing plant with an aerial transferring line G an apparatus C can be provided for transferring the skins on the rods 6 as shown in Figures from 1 to 4, associated to an unstacker A, B as shown in Figure 10; furthermore in order to draw the skins 4 from the rods 6 an apparatus D can be provided as described with reference to Figures from 5 to 8, and a skin stacker apparatus E, F as shown in Figure 9.
