Definitions

  • the shaft is defined on two opposed sides by pivotal guide means located with their horizontal bearing axle below the upper level of the shaft.
  • Each of the guide means has such an extension in the direction perpendicular to the axle that by inclination it can be caused to project into the central area of the drop shaft to deflect centrally dropped objects of a second and, respectively, third dimension to a collecting place on one and, respectively, the other side of the shaft.
  • This invention relates to a sorting arrangement for cross cut wood and similar longitudinal objects.
  • Cross cut wood such as delimbed stern sections, heretofore have been sorted into different assortments (for example, broad-leaf trees, coniferous trees, etc.) in such a way that the crane boom carrying the grapple was swung into a position such that the grapple was placed above the desired wood pocket for dumping the wood thereinto.
  • This permanent shifting between different pockets apparently is tedious and requires high attentiveness of the crane operator.
  • the sorting is still more complicated when the cross cut wood is delivered as a final product directly in a mobile processor where the feeding means for the felled tree together with delimbing and cross-cutting members forms a coherent, relatively rigid unit. In that case, either the entire unit must be made pivotal or the vehicle carrying the unit must be operated between the separate pockets.
  • the sorting arrangement which is characterized in that the arrangement comprises a drop shaft for centrally receiving dropped objects, which shaft on two opposed sides is defined by pivotal guide means located with their bearing axles below the upper level of the shaft and having such an extension in the direction perpendicular to the axle that each guide means by inclination can be caused to project into the central area of the drop shaft so as to catch and deflect the objects dropped centrally to a collecting place on one and, respectively, the other side of the shaft and thereby to divide the objects into three assortments.
  • FIG. 1 shows a side view of the sorting arrangement connected to the outlet end of a processor mounted on a vehicle
  • FIG. 2 shows a plane view
  • FIG. 3 shows a front view of the sorting arrangement
  • FIG. 4 on a smaller scale shows a schematic view of different operations with the sorting arrangement.
  • felled trees are fed to the processor, the outlet end of which is indicated at 2 in FIG. I, and which by a hydraulic means 3 can be lifted and lowered about a bearing axle on the vehicle.
  • a felled tree 4 is slipped down from a buffer supply (not shown) on an inclined guideway 5 and lands between the log feed rolls 6 of the unit. Whilst being advanced by said rolls the tree is delimbed by the indicated shearing members 7 and thereafter cross cut by the folding cross cutting member 8 (see also FIGS. 1 and 2).
  • a forward and a rearward plate 10 and, respectively, 11 (FIGS. 1 and 2) are mounted which I serve as carrying mountings for one end respectively of four parallel axles located substantially on the same level (FIG. 2), of which axles the two central ones are designated by 12 and, respectively, 13, and the two outer ones by 14 and, respectively, 15.
  • the axles are placed symmetrically in relation to the tree path 9, i.e. the outwardly projecting stem 4 being located directly above the gap between the two central axles 12 and 13, so that a cross cut stern section falls down into this gap.
  • Each of the central axles l2 and 13 pivoted with one end in the plates 10 and 11 carries a forward and a rearward guide means 16 and, respectively, 17 (applies to the axle 1112) in the form of a two-armed lever, which by a hydraulic means 20 applyingbetween a lever 18 on the end of the axle l2 and a stationary (during the sorting operation) pin 19 can be turned between a standing and a lying position.
  • Each of the outer axles 14 and 15 is fastened with one end in the plates 10, 1 l and carries a forward and a rearward vertical support 21 and, respectively, 22 (applies to the axle 14). Between said supports is mounted on the axle a tube 23, which at both ends carries an arm 24 and, respectively 25.
  • a hydraulic means 28 acts between a lever 26 (FIG. 3) on the tube 23 and a pin 27 (FIG. 1) at the upper portion of the rearward support 22, by which hydraulic means the tube can be turned about the axle l4 and thereby the arms 24, 25 be swung between the vertical position shown in FIG. 1 and the horizontal position in FIGS. 2 and 3.
  • the sorting is carried out as follows.
  • the sorting operation is carried out comfortably and rapidly from the drivers seat of the vehicle by operating one or the other of the hydraulic means for adjusting the pivot guides to vertical or inwardly inclined position.
  • the driver can, for example, fold up the bottom flap 24 of the left-hand pocket by the hydraulic means 28 and adjust the pivot guide 16 to horizontal position.
  • the volume of the left-hand pocket is increased to include also the drop shaft.
  • the driver also lifts up the bottom flat of the right-hand pocket and adjusts the right-hand pivot guide to horizontal position, so that a large volume for one assortment is obtained (FIG. 4b).
  • the driver For emptying the pockets, the driver first lowers the entire pocket unit to the ground by operating the hydraulic means 3 in FIG. 1, so that the timber is discharged without appreciable drop height when the pockets are opened by folding down their bottom flaps and possibly swinging back the pivot guides, as shown in FIG. 4c.
  • the pocket units could not be raised and lowered, but the timber was dropped without control from a relatively great height, which resulted in an unhandy jam.
  • the axle 14 of the left-hand pocket is supported on a boom 29 projecting outwardly in the transverse direction of the vehicle.
  • Said boom is mounted coaxially with the axle 12 of the pivot guide 16 and includes an extension 30 projecting rearwardly from the point of mounting.
  • the boom 29 is pivotal between horizontal and vertical position and carries the aforementioned bearing pin 19 for the hydraulic means 20. In its horizontal position the boom is prevented from swinging downwardly by its extension 30 abutting an overlying stationary stop member 31, which carries an eye with an axle 32 about which is pivotally mounted at its central portion a hook generally designated by 33.
  • the hook With said hook in the position indicated by fully drawn lines, its inwardly curved lower end portion engages below a stop member 34 mounted at the end of said extension 30 to prevent unintentional upward swinging of the boom.
  • the hook 33 at its upper end portion is provided with a downwardly facing recess 35 and with an upwardly facing recess 36.
  • the boom also includes a stop member in the form ofa pin 37.
  • the relatively heavy pocket is folded up as follows.
  • the driver operates the hydraulic means so that it projects out its rod and turns the lever 18 of the axle l2 (and thereby the pivot guide 16) substantially through to the position indicated by dash-dotted lines.
  • the hook 33 is folded down manually to its dash-dotted position whereby the lower end portion of the hook slides out of the locking engagement with the stop member 34, and the recess 35 embraces a pin projecting from the end of the lever 18.
  • the driver again operates the hydraulic means 20 so that its rod is retracted. Due to the fact that the end of the lever 18 now is fixed, the hydraulic means swings the boom with the pocket carried thereon upwardly through substantially 90.
  • lever-shaped pivot guides for example, the supports and arms may be replaced, for example, by grid constructions or integer plates.
  • the hydraulic means may be replaced by equivalent power means and be varied with respect to their points of application. It is also possible to imagine more than three sorting spaces with a resulting modification of the location and extension of the pivot guides.
  • Apparatus for sorting elongated pieces of wood into assortments thereof comprising supply means for feeding individual pieces of wood in a horizontal position to a drop zone, an axle disposed on each side of the drop zone and below the top of the drop zone, each axle extending substantially parallel to the axes of the pieces of wood, guide members mounted on each axle for pivotal rotation about the axes thereof, said guide members, when in a vertical position, forming the opposed sides of the drop zone and each guide member, when rotated to an oblique angle to the vertical, projecting into the drop zone to deflect falling pieces of wood to a collecting zone disposed laterally of the drop zone, whereby the pieces of wood may be separated into three distinct assortments.
  • said means for rotating said at least one vertical barrier comprises a boom member mounted for rotation about the axis of the associated axle of at least one of said guide members, said vertical barrier and associated bottom flap member being mounted on the outer end of said boom member, rotatable hook means for limiting the rotation of said boom member between an outwardly extending horizontal position and an upwardly extending vertical position, and means for locking said boom member in its vertical position when the vertical barrier and the bottom flap member are in their retracted position.
