Definitions

  • the invention relates to the field of tires, and in particular the packaging and handling of tire casings during the shopping and transport processes.
  • a widely used solution is to use pallets specially sized to receive envelopes of various sizes and diameters.
  • a pallet commonly used in storage magazines is described in US Pat. No. 5,259,325, wherein the envelopes are stored in stack or roll.
  • Pallets of this type have the advantage of constituting homogeneous batches of envelopes, of being able to be arranged on top of one another over great heights, of being able to be handled by mechanical means of the forklift type, and of offer good protection of the envelopes against external aggression. On the other hand, they are less suitable for transport, especially on long journeys, because of the low compactness of the loads and the management of the return of the empty pallets.
  • the object of the invention is to contribute to reducing handling and transport costs while improving the ergonomics associated with storage and retrieval operations.
  • US Pat. No. 6,527,499 describes a method for constituting packaging units in which the envelopes are arranged in spikes or more commonly in the so-called "fishbone" configuration and then compressed vertically between two rigid plates around which there are available means of contention to maintain the batch of envelopes under tension.
  • these packaging units suffer from the disadvantage of including recyclable media whose management complicates the organization of the supply chain.
  • the object of the invention is to propose a method and a device that makes it possible to eliminate the drawbacks mentioned above.
  • the compression ratio of the tire lot as well as the tension and the pitch of the helical winding, it is possible to obtain a lot of tires easily manipulated directly using a forklift truck.
  • Conventional fork without it being necessary to have the lot beforehand on a rigid pallet.
  • the packaged lot has a structural rigidity such that it does not deform when it is grasped by its lower part by the two forks of the carriage.
  • the device shown in FIG. 1 comprises a prepackaging station 200, a compression station 300, a packaging unit 400, a transfer assembly 100, and an evacuation station 500.
  • the prepackaging station 200 is located upstream of the device whose longitudinal direction is marked by the axis XX '. It is at this station that the batch of tires L is constituted.
  • the envelopes are arranged in a jig formed by two vertical planes perpendicular to the longitudinal axis and on which the envelopes located at the two longitudinal ends of the row forming the batch are supported.
  • the vertical planes are materialized by two posts 210 and 220, centered on the axis XX '.
  • the preferred embodiment consists in stacking the envelopes in horizontal layers, arranged vertically on each other by making a lot L on a single row. Similarly to ensure the best structural cohesion of the lot the tires will be arranged according to the configuration called "fishbone".
  • the realization of the stack may be manual, or may be performed using mechanical means not the subject of the present description.
  • the size of the template formed by the spacing of the two posts 210 and 220 is adjustable in the longitudinal direction. Their arrangement allows the operator to easily access the space between the two poles so as to achieve the constitution of the lot L.
  • the size of prepacked batches is 15% to 60% greater in height than the size of the compressed batch that is to be obtained.
  • the length of the row is judiciously chosen and will be equal for example to the width, or to the multiple of the width, of a truck trailer or the larger packaging unit such as a wagon or a container used to carry the transport of lots over long distances.
  • the number of envelopes that can be gathered within the same batch can then vary from a few tens to a hundred tire envelopes.
  • the envelopes are arranged on a conveyor 230 oriented in the longitudinal direction XX 'and aligned with the conveyor of the compression station 330, the conveyors of the packaging unit 430 and 431, and the conveyor of the evacuation station 530 .
  • the pole 220 located downstream is movable in the vertical direction ZZ 'so as to allow the passage of the tire batch from the pre-conditioning station to the compression station.
  • it is equipped with a rack 222 and a motor 221.
  • the device also comprises a transfer assembly 100 whose function is to ensure the longitudinal and transverse stability of the batch of tires L, during the transfer from one station to another and to maintain the batch in the dimensions given by the gauge of the prepackaging station until the tire lot is properly packed.
  • the transfer assembly 100 consists of 4 transfer posts 110, 120, 130, 140, movable in the longitudinal direction XX ', and arranged in pairs, on either side of the conveyors 230, 330, 430, 431 These transfer posts rest on longitudinal rails 101 and 102, and are guided on their upper part by sets of bearings 114, 124, 134, 144, arranged on slides 103 and 104.
  • Each of these transfer posts supports a retaining bar 111 (not visible), 121, 131 and 141, movable transversely and guided by its upper and lower ends by rails 112, 113, 122, 123, 132 (not visible), 133 (not visible), 142 and 143, arranged in the transverse direction YY 'on the upper and lower portions of the transfer posts 110, 120, 130 and 140.
  • Transfer engines (not shown) and animated by the automatic control of the device, allow the longitudinal displacements of the transfer posts and the transverse movements of the holding bars 111, 121, 131 and 141.
  • the transfer station By bringing the holding bars 111, 121, 131, 141 into contact with the parts of the batch of tires situated laterally on either side of the batch and at each of its longitudinal ends, the transfer station ensures the maintenance of the cohesion of the lot in the dimensions assigned to it at the pre-assembly station.
  • the compression station 300 comprises two compression plates parallel to each other and perpendicular to the vertical direction ZZ '.
  • the upper plate is composed of a frame 320 supported by two vertically movable columns 324 and 325. These columns 324 and 325 are connected to a loading system (not shown) and intended to raise or lower the upper compression plate by a given value so as to vertically compress the batch of envelopes L in the direction perpendicular to the layer of envelopes.
  • the charging system may be a mechanical system comprising a set of pinions and racks, or a set of hydraulic cylinders or any equivalent pressurizing system. Its load capacity is of the order of 2,000 daN.

  • This conveyor may be of the conveyor belt type or roller conveyor type. Preferably this conveyor is motorized.
  • the length of the upper plate is adapted to the length of the row of the lot L of tires. Its width is determined to be less than the width of the tire lot L, or the tire diameter when the tires are arranged in a single row. This dimensioning is preferred, so as to allow the movements of the upper plate relative to the holding bars when the latter are maintained in contact with the batch L during the compression phase.
