Definitions

  • the invention concerns a winding/unwinding machine and a method for sequential storage and collecting of hides using this machine.
  • the methods employed for the stocking or temporary storage of hides are based on criteria that give primary importance to space saving, though guaranteeing the physical soundness of each single hide, in order to facilitate the successive processing stage to which the hides must be subjected.
  • the known machines suitable for implementing the method described above and called “stackers” substantially comprise a frame supporting a conveying surface with mainly longitudinal development, on which the hides are laid in such a way as to be transported and then put on a retractable plane that unloads them on a pallet.
  • the retractable plane has a mainly longitudinal development and is located in a substantially horizontal position under the conveying surface, from which it protrudes due to the fact that is horizontally movable at a variable distance from the ground. Under the retractable plane there is a pallet where the hides are stacked.
  • the retractable plane is anchored to the frame, so that it can shift horizontally and disappear under/protrude from the conveying surface and is provided with rollers positioned transversally with respect to the development of the plane and defining the hide support surface.
  • the retractable plane must gradually protrude from the conveying surface itself, until the hide has been completely deposited on it.
  • the plane is retracted and at the same time the rollers are rotated so that the hide, owing to the reciprocal travel motion of the plane and rotating motion of the rollers in the opposite direction, remains positioned on the pallet and falls on the hides that have already been stacked due to the force of gravity.
  • Appropriate anchorage devices provided on the material handling means permit the anchorage and successive transport of the hide pile towards the successive processing station or towards the warehouse.
  • the successive collection of the hides from the piles created by the stackers to feed, for example, the machine that must carry out the following processing stage is performed manually, in fact the operator takes the hides one by one and positions them on the machine.
  • the main drawback of the stocking method described above is constituted by the considerable space occupied by the hides, which, being laid and stacked over one another, occupy a surface that corresponds at least to their own surface.
  • Another drawback is due to the numerous kinematic motions of the stacker, which are necessary to operate the retractable plane and the rollers and to adjust their distance from the ground.
  • US-A-3,813,843 discloses an apparatus for rolling cut filter pads. Said fitter pads are delivered to a roll station where kraft paper is drawn. The cut pads and the kraft paper are wound onto a take-up roll until a given number of cut pads have been wound.
  • the aim of the present invention is the achievement of a method and a machine that make it possible to overcome the inconveniences mentioned above.
  • the main aim of the invention is the implementation of a method for the sequential storage of hides that makes it possible to store them occupying the least possible space, without affecting the properties of the hides themselves.
  • Another aim of the invention is to implement a method that permits to store hides of any length and ensure effective management of space in comparison with the known methods.
  • Another goal is the implementation of a machine that applies the method object of the invention and permits the automatic storage and collection of hides.
  • a further aim is the implementation of a machine that makes it possible to record the positions occupied by each single hide, with the relevant information, so that it can be successively directed towards the most suitable production processes.
  • Another aim is the implementation of a simple and economic machine in comparison with the known types of machines.
  • the machine must have limited overall dimensions, independently of the size of the hides to be stored.
  • the method described makes it possible to store the hides so that they can be automatically collected with no need for the intervention of an operator.
  • a further advantage is represented by the fact that the machine constructed in this way is reversible and therefore can be used either for storing hides and for collecting hides that were previously stored.
  • the machine constructed in this way is very simple and compact if compared with the known machines.
  • the hides are substantially wound around a cylindrical support to form a spool in which the hides are separated by a flexible foil that constitutes the core of the spool.
  • the hides transported by a conveying surface are stored sequentially, said conveying surface defining a longitudinal advancement direction and being designed so that the hides are positioned on it one after the other.
  • the storage operation substantially comprises the following stages:
  • the winding of the flexible foil must take place at the same time as the deposit of the hides on the flexible foil itself.
  • the winding/unwinding machine object of the invention shown in Fig. 1, where it is indicated as a whole by 1, is suitable for winding/unwinding hides around/from a spool according to the method described and substantially comprises a frame 2 resting on the ground T provided with a driving unit, indicated as a whole by 3, for the flexible foil 4 that is wound together with the hides P positioned on it in such a way as to form the spool 5.
  • the driving unit 3 is positioned after the conveying surface S on which the hides P are laid one after the other and comprises a winding unit for the flexible foil 4, indicated as a whole by 6, and a similar unwinding unit for the same flexible foil 4, indicated as a whole by 7.
  • the winding unit 6 defines the rotation axis 8 for a cylindrical support 10 of the spool that will be formed, said rotation axis 8 being arranged in substantially orthogonal position with respect to the advancement direction of the flexible foil 4.
  • the unwinding unit 7 defines the rotation axis 9 of a cylindrical support 11 around which the flexible foil 4 is wound, said rotation axis 9 being substantially orthogonal to the advancement direction of the flexible foil 4.
  • the winding unit 6 and the unwinding unit 7 are provided with reversible powering means suitable for setting them rotating on their own axis and are spaced from each other, so that the flexible foil 4 defines a substantially rectilinear section 12, preferably but not necessarily inclined, in correspondence of which the hides P transported by the conveying surface S are deposited.
  • the machine described above can be used as either winding or unwinding machine by simply reversing the rotation directions of the winding unit 6 and unwinding unit 7.
  • the hides P positioned on the conveying surface S advance along the direction 20 until reaching the flexible foil 4 that at the same time is unwound from its cylindrical support 11, the latter being set rotating by the winding unit 6.
  • the hides P and the flexible foil 4 joined together are wound around the cylindrical support 10, thus forming the spool 5 represented in detail in Fig. 2.
  • the spool 5 formed by the wound hides is also positioned on the winding unit 6, while the direction 20 of the motion of the winding unit 6 and of the conveying surface S will be inverted.
  • This machine differs from the previous one because it has a conveying surface 21 belonging to the machine structure and connected to the frame 22 through connection means suitable for permitting the variation of its inclination with respect to the direction of advancement 30 of the hides P.
  • the hides P transported by the conveying surface S' reach the conveying surface 21, from which they will be deposited onto the flexible foil 4 already wound around the spool 51.
  • the conveying surface 21 changes its inclination 60, in such a way as to guarantee a more suitable and correct arrangement of the hides P on the flexible foil 4.
  • the winding unit 61 is removable, in fact it is provided with sliding wheels 62 that allow it to be moved away from the frame 22 of the machine itself.
  • the flexible foil 4 can be preferably, but not necessarily be constituted by transpiring materials, such as paper, fabric, holed plastic, or other similar materials.
