Definitions

  • 263332535 be wckingly mounted about axles in Parallel M the 581 Field Of Search ..l98/l67, 127, 200-, 193/37; we, that always adjacent Plates can adjust 144/246 R, 246 A, 246 C; 29/121; 226/124, 192
  • This invention relates to a means for feeding longitudinal objects, such a timber, in their longitudinal direction in such a way that the object is taken along by its contact with jagged plates, which extend to the side of each other along the outer surface of a rotary roll in the longitudinal direction thereof.
  • Jagged rolls of the conventional type when they are utilized for feeding logs do not satisfactorily safely engage with the logs, because the continuously curved outer surface of the roll provides only for a short distance contact between the log and the jags.
  • This less effective engagement results in a sliding of the logs and damaging of valuable surface wood, and it further causes jerkiness and time losses in the feeding operation, which has a reactive effect on the subsequent processing steps, such as delimbing, barking, crosscutting etc., which in many cases are fully automatic or semi-automatic.
  • the present invention follows an entirely different way.
  • the feeding means according to the invention is characterized in that the plates are rockingly mounted about axles in parallel with the axle of the roll.
  • FIGS. 1 and 2 show in sections schematic end views of two different embodiments of the roll comprised in the feed means
  • FIG. 3 shows a longitudinal section through a roll corner at the embodiment according to FIG. 1, and
  • FIG. 4 shows a spread view of the outer surface of the roll.
  • 1 designates one end wall of a longitudinal rotary roll, which end wall here is of polygonal shape.
  • a rod 2 extending between the two end walls of the roll is rotatably mounted at its ends in each corner of the polygonal end wall periphery, for example via an end journal received in a corresponding recess in the edge portion of the end wall.
  • extra supporting members or intermediate end walls may be placed between the outer end walls.
  • a plurality of rods 2 extend between said end walls, each rod being rotatably mounted adjacent a comer of the polygonal end wall periphery.
  • Each of said rods carries a longitu dinal plate 3, which in its turn carries on its upper surface a set of jags 4 of conventional design.
  • these jags are shown in groups arranged in inclined parallel rows with connection one to the other from one plate to the other.
  • the plate 3 projects with each end beyond the end wall periphery, as shown in FIG. 3, and can then rock about the central axle A of its rod 2 between the two end positions defined by the abutment of the plate to one or the other of the straight end wall edges 5 on both sides of said corner.
  • the dash-dotted lines in FIG. 1 indicate the end positions inclined to each other of two adjacent plates.
  • an overlying resilient pressure member which may be a pressure-actuated smooth roll or a roll similar to the underlying one, at first the jag row, which is located farthest ahead in the feeding direction (counterclockwise in the Figure) on the uppermost plate contacting the log, catches the log, followed by the second, third and fourth row, whereafter the plate along its entire width is in engagement with the log.
  • FIG. 4 also shows the pattern of arrangement of the jags 4, viz in parallel rows inclined relative to the longitudinal direction of the plate and extending aligned from one plate to the other.
  • the plate 3 carrying the jags 4 is mounted on a semicylindric member 6 instead of on the round rod 2 in FIG. 1.
  • the ends of said member 6 can be received in corresponding recesses on the inside of the edge portion of the end wall I, but the mounting proper is moved to the central line B for the upper surface of the plate 3, along which line a trunnion can project into an edge flange 7 (indicated by dash-dotted lines) with connection to the end wall.
  • the flattening can be carried out such that, after desire, the upper surface of the plate is located above the rocking point of the rod, as in FIG. 1, or on the same level as the rod, as in FIG. 2.
  • the mounting proper of course, also may be varied in many different ways. instead of mounting the ends of the members carrying the plates in the end walls proper, the roll can be provided with a shell of a thickness sufficient to include longitudinal mounting grooves for round bar or semicylindric members. Furthermore, the stop members for the rocking motion of the plates can be designed in a different way than shown.
  • the plates may, in principle, be arched somewhat in which case the jags preferably should have a height varying in the transverse direction of the plate, so that the points of the jags substantially terminate in the same plane.
  • the invention can also be applied to longitudinal objects other than logs.
  • a feeding rotary roll for advancing elongated objects, such as timber, in their longitudinal direction comprising a peripheral surface formed by a plurality of jagged plates extending adjacent to each other along the longitudinal direction of the roll, each plate being provided with pivot means enabling the plate to rock around an axis parallel with the axis of the roll, and means limiting the rocking motion of each plate.
  • a feeding roll according to claim I wherein the plates have a plane upper surface supporting plural rows of jags of equal height.
  • a feeding roll according to claim 2, wherein said means for limiting the rocking motion of the plates comprises stop members for defining an end position for the plates, in which position each pair of plates rocked towards each other are located in the same plane.
  • each plate is pivoted about an axis substantially coinciding with the center line for the upper surface of the plate.
  • each plate is pivoted about an axis which, seen in the direction towards the center axis of the roll, is located below, and in parallel with, the center line for the upper surface of the plate.
