Definitions

  • a reciprocable locking member is arranged substantially perpendicular to the transverse direction of the pocket and has control means cooperable with a control portion on ,each bottornwhereby in a first position any bottom not arrested by the control arrangement swings to an open position via gravity and in a second position the opening of any bottom is prevented regardless of the control arrangements condition.
  • the present invention relates to apparatus for handling sawn woodand more particularly to an installationsuch as a saw mill whereinsawn wood is processed and transported between different machinesor intermediate storage places.
  • Sawn wood of different grades or dimensions is frequently sorted intoione pocket:or compartment for each grade or dimension and, after a predetermined quantity has been accumulated or at a predetermined time, the entire contents of one or more pockets or compartments is then transferred -to a transport means such as-a conveyor or a vehicle.
  • the invention relates to new and improved selectively openable bottom means for intermediate storage pockets or compartments of the type described, including selectively operable arresting and releasing means for each individual openable bottom and a common control means for all of the bottoms of the pockets or compartments in one group of such pockets or compartments.
  • the object of this invention is, therefor, to provide an apparatus of the type described in which one or more of the pockets or compartments may be emptied selectively and simultaneously employing but one source of motive power common to all of the pockets or compartments.
  • each of the pockets or compartments is provided with a door like pivotable bottom component and an electromagnetic arresting and releasing member co-operable with the bottom component, the bottom components being arranged to swing or pivot into an open position due to the effect of gravity acting upon 3,498,503 Patented Mar.
  • FIGURE 1 is -a side elevational view with certain parts being shown in section of an apparatus embodying the present invention
  • FIGURE 2 is a view taken along the line IIII, and
  • FIGURE?) is a view generally similar to FIGURE 1 illustrating the apparatus during an unloading operation.
  • the present apparatus includes a plurality of adjacent substantially parallel pockets or compartments 1 of ap proximately rectangular cross section.
  • the pockets are divided or separated from one another by vertical partition means constituted by vertically disposed bars 2 the lower ends of which are affixed to transverse horizontal members 30f triangular. cross section.
  • the bottom of each pocket 1 is defined by a plurality of bars 4 which are secured at one end to a shaft 5 having a reduced portion 6 at'either end with the reduced portion 6 being journaled in bearings 7 as illustrated-in FIGURE 2.
  • control means 8 and arms 9 In proximity to the endsof the shaft 5 are located control means 8 and arms 9 and it will be noted that the armsv9 incline upwardly from the shaft and are provided with metal plates 10 at their upper free ends.
  • the plates 10 function as armatures for electromagnets 11 which are secured to the transverse horizontalmembers 3.
  • a horizontal shaft 12 is arranged directly below the control means 8 at the opposite ends of the pockets or compartments 1 (FIGURE 2).
  • the shafts 12 are parallel with the direction of movement or the transport direction of a conveyor 19 which moves below the pockets and the shafts 12 are journaled at each end in bearings 13.
  • Each shaft 12 is reciprocable by means of a hydraulic or pneumatic assemblage 14, the piston of which is connected to the shaft 12 in any suitable and convenient manner.
  • the shaft 12 may be reciprocated by a manually operable handle 21 which is provided with a fixed pivot 22 at one end thereof and is slidably attached to the shaft 12 by suitable members 23 at an intermediate location as clearly illustrated in FIG- URE 3.
  • the shaft 12 carries a control member 15 for each pocket or compartment 1 and such control member is defined by a cylindrical sleeve 16 having two protruding members or ears 17 between which a contact roll 18 is arranged with the contact roll 18 being co-operable with the control means 8.
  • each electromagnet 11 is energized and holds the corresponding plate 10 thereby preventing the shaft 6 from rotating and maintaining the bars 4 in an essentially horizontal closed orientation.
  • the magnet or magnets 11 corresponding to the pocket or pockets to be emptied are supplied with a deenergizing pulse in a known manner from a convenient switching means. The pulse will cause the magnet or magnets to become inoperable for retaining the plate or plates 10 and consequently gravity acting upon the bars 4 and/or the sawn wood resting on the bars tends to force the bars downwardly into an open vertical position.
  • the magnets are arranged to be switched into a secondary circuit including an auxiliary source of current such as an accumulator 24 in a fashion which is of course, well known per se.
  • the present apparatus permits a selective simultaneous discharge of the contents of one or more of all of the pockets or compartments 1 as a consequence of a deenergizing pulse being fed to one or more or all of the electromagnets and a subsequent displacement of the shaft 12.
  • the triangular vertical member 3 imparts a suitable form to the bottom of the pockets or compartments and a sturdy and rugged attachment for the electromagnets.
  • a selectively operable control arrangement including an electrically operable electromagnetic arresting and releasing means associated with the bottom of each pocket, said bottom being adapted, when released to swing into an open position under the influence of gravity, at least one reciprocable locking member arranged substantially perpendicular to the transverse direction of the pockets, control means on said reciprocable locking member and a control portion on the bottom of each pocket with which saidcontrol means cooperates so that when the reciprocable locking member occupies a first position, any bottom not arrested by said electromagnetic means will be free to swing into an open position under the influence of gravity, and a second position in which the opening of any of the bottoms is prevented, regardless of the condition of the electromagnetic member.
  • said electromagnetic arresting and releasing means comprises an armature attached to a component of the pivotable bottom and an electromagnet attached to a stationary part of the apparatus.
  • each pocket includes a plurality of bars secured at one end to a pivotable shaft and having their opposite free ends extending in the direction of movement of the transporting means, with each bar having a broad, V-shaped vertical longitudinal section 4.
  • said reciprocable locking member comprises a shaft adapted to be reciprocated by a fluid pressure operated assemblage having a piston coaxial with the shaft.
