Definitions

  • the invention relates to a method and a device for loading and unloading a bulk product on a reel for processing this product.
  • Certain treatments of bulk product in particular filtration or separation of the phases which constitute it, consist in distributing this product in relatively thin layers on a support and in treating these layers (application of a spin pressure, washing ... .).
  • the invention intends to propose a method which allows relatively simple automation of these operations and an implementation carried out with a minimum number of members adapted to serve several treatment stations. in a machine.
  • the method according to the invention consists, for unloading, of coupling the free end of this fabric to a secondary spool located directly above the spool, of forcing the fabric to pass over a deflection roller by shifting the latter by relative to the two reels, to drive the secondary reel to wind the canvas therein, so that the product leaves the canvas by gravity, at the deflection roller and, for loading, the canvas being previously wound on the secondary reel and coupled to the main spool at its other end, passing over said offset idler roller, to wind the fabric on the main spool while depositing the material between the return and said reel, retract the return roller and then unhitch the fabric of the secondary reel.
  • the invention also provides a device for implementing the above method which comprises: - a motorized support of a main coil; - A secondary coil located substantially in line with the main coil, also motorized and provided with a releasable fixing means for one end of a fabric, the other end of which is fixed on the coil to be loaded and unloaded; - a roller with an axis parallel to that of said coils, displaceable parallel to itself on a fixed guide disposed between the two coils and perpendicular to the section of canvas extending between the coils, between a first retracted position where it is out of contact with the fabric and a second active position where it is in contact with the fabric to force it to form a substantially horizontal loop between the two coils.
  • the means for moving the deflection roller are constituted by two endless flexible drive members which are parallel to each other and to which the ends of the roller are coupled, a support table for the upper strand of the fabric being disposed between said members, behind the roller relative to its direction of movement from its first to its second position.
  • the motorized support of the main coil belongs to a fixed frame of the pressing machine and can move the coil parallel to its axis from a treatment position, for example inside an enclosure, up to a loading-unloading position, outside this enclosure.
  • the secondary coil can be carried by a secondary support located under the main coil in position loading-unloading.
  • the secondary support can also support the deflection roller and the mechanism which makes it possible to move it to form the above-mentioned loop.
  • the secondary support can be movable along a guide path extending in front of each of these stations, up to a loading station which can be constituted by a hopper the product.
  • the secondary coil or coils are fixed, under the main coil or coils and the deflection roller is movable along a substantially horizontal fixed guide extending in an intermediate plane between the main coils and the secondary coils .
  • the support for the secondary coils and the deflection roller also constitutes the motorized support for the main coils which are extracted from the treatment enclosure and can thus be brought to an unloading station and a loading station.
  • the secondary coil (s) advantageously have a slot in their hub for the removable fixing of the free weighted end of the fabric.
  • FIGS 1 to 7 we see a main coil 1, a secondary coil 2 located directly above the main coil, a deflection roller 3 movable by drive means 4 which extend in a substantially horizontal plane between the coils 1 and 2.
  • These figures also show a loading hopper 5 for a product P to be treated and a conveyor 6 for discharging the treated product P ′, and a secondary roller 7 for guiding the fabric 8 which flows between the two coils, when the deflection roller 3 is in its active position.
  • the various supports of these members are not shown in the figures. They will appear next to the following figures.
  • the coils 1 and 2 are coupled to drive and rotation control members allowing the winding and unwinding of the fabric with possibilities of adjusting its tension.
  • Figure 1 shows the device in the initial state, that is to say when the loading of the coil 1 will begin.
  • the fabric 8 is fully unwound from the reel 1 on which it is fixed by one of its ends.
  • the deflection roller 3 is in its active position in which it forces the fabric 8 to form a loop 9 between the coils, the upper strand 9 of which is substantially horizontal.
  • the movement of the roller 3 is carried along the upper run 4a of the actuator 4 which is constituted by two parallel endless chains to which is fixed the roller 3.
  • These chains are behind the roller 3 a plurality of slats 10 which form a table on which the strand 9 a of the cloth 8 can rest, in particular under the action of the secondary deflection roller 7.
  • the fabric 8 is therefore deformed into a loop 9 and wound on the secondary coil 2.
  • the loop 9 extends as far as under the hopper 5 or at least as far as its distribution opening (which may include a product drive belt).
  • the coil 1 is rotated to wind the fabric with the product P which is deposited there. This phase is shown in Figure 2.
  • FIG. 4 shows the end of the winding of the fabric on the spool 1 and the release of the attachment of the fabric to the secondary spool 2.
  • the roller 3 is in a retracted position 3 ′.
  • FIG. 4 and FIG. 5 there has been a treatment of the loaded fabric wound on the spool 1, this spool having been moved from this unwinding winding station to a treatment station, then brought back to its position d 'origin.
  • actuating its motorization one begins the unwinding of the fabric 8 whose end 8 a , preferably ballasted, is housed in a slot 2 a of the coil 2 provided for this purpose. The end of the fabric is therefore immobilized in the coil 2.
  • FIG. 6 illustrates the movement of the roller 3, perpendicular to the section of fabric between the coils 1 and 2, and the resulting formation of the loop 9, the fabric being deflected by the roller 3.
  • Figure 7 finally shows the unwinding of the fabric which is wound on the spool 2 driven in rotation.
  • the residual product P ′ located on this fabric is detached from it when the roller 3 passes and falls onto the conveyor belt 6 for evacuation.
  • the fabric can, between the roller 3 and the spool 2 undergo an appropriate cleaning treatment.
  • coils 1 a and 1 b drawn in dashed lines, which illustrate the fact that the product processing machine (for example pressing) can have several stations.
  • the schematically illustrated loading-unloading device can serve each of these stations if the cycle times allow it and if the coil 2 can be brought in line with each of the coils 1, 1 a and 1 b .
  • the stroke of the roller 3, by means of its driving device 4 is sufficient to be able to intercept each of the strips coming from the reels and to form a loop 9 with each of them.
  • FIG. 8 schematically shows that the coil 2 can be secured to a carriage 11 which moves from one to the other of the coils 1, 1 a , 1 b .
  • This carriage 11 can also carry the secondary deflection roller 7.
  • FIG. 9 is a diagram in which the carriage 12 additionally has the means for taking charge of each of the coils 1, 1 a , 1 b when they leave the processing station to transport them to an unloading station 13 and under a loading station 14.
  • the roller 3 and its drive mechanism 4 are also carried by the carriage 12.
  • the mechanism 4 can, in this variant embodiment, have a shape other than that of endless drive chains. It can in particular be cylinders pushing the roller 3, taking into account the fact that the travel of this roller is much more limited than in the previous cases.
  • each coil 1, 1 a , 1 b is associated with a fixed coil 2, 2 a , 2 b and secondary return rollers 7, 7 a 7 b also fixed.
  • the roller 3 is driven, as the table 10 by a pair of endless chains or cables 4.
  • This figure shows the loading or unloading of the coil 1 a while the other two coils undergo processing phases (for example a radial pressing in chambers 15).
  • the motorized support of the coils 1, 1 a , 1 b comprises a horizontal arm parallel to the axis of each enclosure 15 and passing through it which makes it possible to move each coil from the inside to the outside of the enclosure and vice versa and, in the external position, to rotate it around its axis.
  • each coil 2 has a slot 16 in which the end 8a, ballasted, is accommodated to be trapped by a folding flap 17 or any other suitable device in the case of unwind the fabric from the spool 1, and to be released at the end of the winding of the canvas on the spool 1.
  • One of the interesting applications of the invention is the loading and unloading of the coils of a machine for pressing a product (for example a pulp) in order to extract the liquid phase therefrom.
  • the invention also applies to the handling of a product from a storage station to any treatment station and from this station to an evacuation station, insofar as the treatment of the product involves its winding in layers around a cylindrical core.
