Definitions

  • the present invention relates to a machine for packaging firewood logs, arranged in bulk in a flexible holding structure.
  • the logs of short firewood that is to say usually having lengths of the order of 25, 33, 45 or 50 centimeters, are generally packaged in bundles of low volume. Such a presentation in fagots considerably complicates handling and increases the cost of the final product. In addition, an orderly presentation slows down or prevents the drying of the wood which is quick and efficient only if the logs are arranged in bulk, leaving air to flow between them.
  • German utility model DE 202010003 U1 describes an individual device arranged to package small bulk elements, including firewood sticks using a flexible grid-shaped tape wrap.
  • the strip is unwound around a bundle of sticks and reassembled laterally to form said wrapping.
  • It is an individual apparatus for forming substantially cylindrical packages and having a kind of mold to be removed vertically after said wrapping.
  • the Swiss patent CH 696761 A5 describes a device substantially equivalent to that of the German utility model, also in the form of a single device, comprising a cylindrical mold to be lifted as filling.
  • the French patent application published under No. 2,976,256 discloses a bulk product palletizing mechanism with bandaging means for creating a progressive package of pieces of wood or the like carried by a rotary pallet and packed in a net held vertically by a mast. It is a fixed equipment comprising several drive members, respectively a base, a support of wood pieces and relatively complex and expensive net holding means.
  • the present invention proposes to provide a solution to the problem posed by the conditioning of firewood logs, for their transport and storage, the packaging means being arranged to ensure efficient drying of the wood during storage.
  • the machine according to the invention as defined in the preamble and characterized in that it mainly comprises means for depositing a batch of logs on a pallet and means for wrapping said logs in at least one layer of a band consisting of a net with large mesh, arranged to allow the passage of air.
  • said means for depositing a batch of logs on a support pallet comprise on the one hand a device for feeding said logs and on the other hand a device for confining said logs arranged in bulk on said pallet, in the form of a batch of predetermined volume, in a delimited space of substantially cylindrical shape.
  • Said feed device of said logs advantageously comprises a belt conveyor equipped with a weir and said device for confining said logs arranged in bulk on said pallet, advantageously comprises a rotary support carrying said pallet driven in rotation and a cylindrical drum open to its two ends disposed above said pallet.
  • Said cylindrical drum is preferably suspended from a mobile support and arranged to be moved up between a low position where it is placed on said pallet and a high position where it is positioned above the batch of logs deposited on the pallet.
  • said device for confining said logs arranged in bulk in the form of a batch comprises a coil of a mesh of large mesh, said coil being arranged to be displaced in height substantially simultaneously to said drum cylindrical, one end of said strip being fixed to the logs and said net being unwound under the effect of the rotation of said pallet carrying the batch of logs, to wrap said batch of logs in at least one layer of said net with large stitches.
  • the machine advantageously comprises a flat platform carried by a chassis comprising a first operational sector for storing a plurality of empty pallets, a second operational sector for accommodating means of motorization of the active components for the purpose of conditioning said logs, a third operational sector for packaging the logs in a wrapped batch in at least one layer of a large mesh net and a fourth operational area for storing each batch of wrapped logs on a pallet.
  • Said first operational sector is preferably delimited by four columns, fixed to longitudinal members of the chassis, connected in pairs by horizontal crosspieces and comprises two horizontal cylinders, arranged on either side of the chassis to actuate transverse bars, parallel between they move the pallets, one by one, on the platform.
  • Said second operational sector preferably comprises a drive motor and a hydraulic generator supplying a hydraulic reservoir comprising a hydraulic distributor connected to active hydraulic components of the machine.
  • Said third operating sector comprises said rotary support carrying said pallet driven in rotation and said cylindrical drum open at both ends suspended above said pallet to a horizontal crosspiece carried at its two ends by two hydraulic cylinders respectively associated with two vertical columns solidary respectively of the two longitudinal members of the chassis.
  • said rotary support is rotated about a vertical axis perpendicular to the flat platform of the frame by a belt coupled to a drive roller mounted on the output shaft of a hydraulic motor.
  • Said fourth operational sector comprises a transfer device consisting essentially of a transverse roller rotated by a hydraulic motor and several free-rolling transverse rollers on which the pallet loaded with a batch of logs is moved.
  • Said transverse roller preferably has a crenellated surface to allow to hang the surface of the base of the loaded pallet and start its movement.
  • the machine 10 comprises a frame 11 equipped with two pairs of lateral wheels 12 respectively mounted on two transverse shafts and a front steering wheel 13 articulated on a vertical support 14.
  • the frame 11 has a rectangular shape consisting mainly of two longitudinal members 11a and two crosspieces 11b advantageously consist of T-shaped metal sections.
  • the frame 11 further comprises two longitudinal rails 11c, parallel to the longitudinal members 11a which define a flat platform P which is delimited into different operational sectors.
  • the first operational sector 110 located towards the rear of the platform P, is dedicated to the storage of empty pallets which are superimposed and which are subsequently intended to receive a batch of logs, preferably of the order of one m 3 , packaged according to a particular mode, which will be described in more detail later.
  • the frame advantageously carries four columns 16, preferably fixed by bolts or welded to the longitudinal members 11a. These columns are connected in pairs by horizontal crosspieces 16a which delimit the operational sector 110 along the length of the flat platform P.
  • Two horizontal cylinders 17, arranged on either side of the frame 11 cooperate with transverse bars 17a, parallel to each other for moving the pallets 15, one by one, under the operational sector 120 and to the operational sector 130 where they will be responsible for their batch of logs.
  • the second operational sector 120 houses the engine 18 of the machine 10, which comprises a thermal or electric drive motor 19 of a hydraulic generator 20 equipped with a hydraulic fluid reservoir 21 provided with a hydraulic distributor 22, this distributor being intended to supply all the active hydraulic components, such as for example the hydraulic cylinders 17 and / or a hydraulic motor for rotating the pallets 15 in the operational sector 130.
  • the set of active components of the machine 10 is hydraulically driven. Nevertheless other engines, especially electric or pneumatic could be considered.
  • the third operational sector 130 is equipped with a support 23, rotatable about a vertical axis, mounted perpendicular to the flat platform P of the frame 11.
  • This support is preferably driven by a belt 24 coupled to a drive roller 25 mounted on the output shaft of a hydraulic motor 26.
  • the support 23 has the form of a rotating wheel arranged flat, on which is deposited a pallet 15 taken from the pallet stock of the first operating sector 110.
  • This pallet 15 is transferred flat in translation on the platform P of the frame 11 by passing from the first operating sector 110 to the third operating sector 130.
  • the pallet 15 is in place on the rotary support 23, the latter is rotated with the pallet 15 .
  • a cylindrical drum 27 open at both ends, and having approximately the diameter of the rotary support 23.
  • the cylindrical drum 27 is suspended from a horizontal cross member 28 carried at both ends by two hydraulic cylinders 29 respectively associated with two vertical columns 30 integral with respectively two longitudinal members 11a of the frame 11. Said hydraulic cylinders 29 are arranged to move vertically upwards and downwards the horizontal cross member eh causing in its movement the cylindrical drum 27. Initially, the cylindrical drum 27 is positioned so as to rest on the surface of the pallet 15 which is on the rotating support 23.
  • This coil 32 can rotate freely around a vertical axis 35, able to move vertically along the vertical column 31 under the action of a hydraulic cylinder 36. It can thus unwind the band of large mesh net while moving upwards and towards the bottom by ensuring a tight wrapping of objects deposited on the pallet 15 driven in rotation, namely logs B deposited in bulk. This process will be described in more detail below.
  • a conveyor belt or rollers 37 mounted within a guide channel 38 logs, preferably brought by an elevator 39 and discharged by a spillway With ramp inclined 40 in the cylindrical drum 27.
  • the logs fall on the pallet 15 disposed on the rotary support 23 and are positioned in bulk in the cylindrical space defined by this drum.
  • the cylindrical drum 27 begins to be raised by raising the horizontal cross member 28 by means of the hydraulic cylinders 29.
  • a first loop of the large mesh net is wrapped around the base of the pile of logs, which begins to appear because of the rise of the cylindrical drum 27.
  • the logs continue to be poured into the cylindrical drum 27 and the pallet carrying these logs continues to rotate unwinding the reel of large mesh net to wrap the pile of logs as the drum goes up.
  • the cylindrical drum 27 serves only as a template for temporarily holding the logs, knowing that the final maintenance is provided by said net.
  • the fourth and last sector 140 defines a storage zone of at least one pallet 15 loaded with a batch of about 1 m 3 of logs B wrapped and held by the net with large mesh.
  • the loaded pallet 15 is transposed from the sector 130 to the sector 140 by a transfer device composed essentially of a transverse roller 41 rotated by a hydraulic motor 42 and several free-rolling transverse rollers 43 on which the pallet is moved.
  • the transverse roller 41 has a crenellated surface to allow the surface of the base of the pallet 15 to be hung and to start its movement.
  • the pallet 15 is stopped by a stopper or the like (not shown).
  • one or more loaded pallets 15 may be momentarily stored in the fourth sector 140.
  • the pallets loaded with a view to using the logs are preferably taken laterally, these pallets being able to be supported. by a forklift or the like.
  • the machine 10 may be stationary, the side wheels 12 and the front steering wheel 13 being intended solely for its initial placement, or mobile to be transported by road to an operating site.
  • the operation is carried out as follows, with an initially bare machine.
  • a log cleaning unit (not shown) which can be independent or integrated, intended to remove chips, sawdust, dust or splinters of wood or bark.
  • This unit is provided with a vibrating device or the like.
  • the user equips the machine with an elevator 39 and a conveyor belt or rollers 37.
  • it sets up at least one pallet 15 in the first operational sector 110.
  • the engine is activated for the components hydraulics are powered.
  • the next step is to bring a pallet 15 onto the rotating support 23 which is rotated to drive the pallet 15.
  • the cylindrical drum is lowered at the pallet and the logs can begin to be poured onto the pallet 15 in the space delimited by the drum. Thereafter we begin to raise the drum and set a first round of the band of large mesh net around the batch of logs. The cylindrical drum 27 and the reel of the tape are then slowly raised in order to wrap the batch of logs to condition it on the pallet 15.
  • This procedure solves the problem posed by the invention.
  • the operation can be semi-automatic or fully automated. In the latter case an equipment consisting essentially of a programmable controller and a few sensors must complete the described components.
  • the present invention is not limited to the embodiment described, but may be supplemented by complementary arrangements while respecting the objectives defined.
  • the number of empty pallets and the pallets loaded with their firewood batch can be modulated according to the dimensions of the machine. As a stationary machine its dimensions can be more generous than those of a mobile machine which must meet standards imposed by road regulations.
