Apparatus for piling boards

Claim 1

An apparatus for stacking boards to a predetermined height which comprises, in combination, a feeding conveyor for successively introducing boards lying flat on said conveyor to the apparatus, vertically erecting conveyor means on which the boards are excitecd, extending downwardly from the feeding conveyor, a transporting conveyor for receiving and transporting the erected boards to the discharge end thereof, said transporting conveyor being provided with a board reclining support associated therewith near the end portion of the erecting conveyor for receiving and holding the boards while they are being conveyed on the transporting conveyor, a discharge conveyor for removing the boards from the transporting conveyor, a reversing gear comprising an L-shaped member rotatably disposed about the discharge end portion of the transporting conveyor, said L-shaped member containing a board erecting base and a board piling up base disposed at substantially right angles with respect to each other and adapted to be operatively cooperative with each other, said board erecting base being rotatable from a recessed position below the transporting conveyor to a substantially vertiCal position and said board piling up base being simultaneously rotatable from a substantially vertical position to a recessed position below the discharge conveyor, and means for rotating the board erecting base and the board piling up base.

Claim 2

An apparatus for stacking boards to a predetermined height which comprises, in combination, a feeding conveyor for successively introducing boards lying flat on said conveyor to the apparatus, vertically erecting conveyor means on which the boards are excitecd, extending downwardly from the feeding conveyor, a transporting conveyor for receiving and transporting the erected boards to the discharge end thereof, said transporting conveyor being provided with a board reclining support associated therewith near the end portion of the erecting conveyor for receiving and holding the boards while they are being conveyed on the transporting conveyor, a discharge conveyor for removing the boards from the transporting conveyor, a reversing gear comprising an L-shaped member rotatably disposed about the discharge end portion of the transporting conveyor, said L-shaped member containing a board erecting base and a board piling up base disposed at substantially right angles with respect to each other and adapted to be operatively cooperative with each other, said board erecting base being rotatable from a recessed position below the transporting conveyor to a substantially vertiCal position and said board piling up base being simultaneously rotatable from a substantially vertical position to a recessed position below the discharge conveyor, and means for rotating the board erecting base and the board piling up base.

Claim 8

An apparatus for stacking boards which are successively fed to said apparatus individually or in small stacks and in a flat position which comprises a feeding conveyor including a roller conveyor capable of feeding the boards or stacks of boards as they are lying in said flat position, an erecting conveyor on which the boards are erected including endless transporting belts provided in parallel relationship, said transporting belts containing transporting faces which are downwardly inclined, one end of said belt being disposed under the discharge end of the feeding conveyor so that the individual boards or small stacks thereof may be raised by dropping from the feeding conveyor onto the erecting conveyor, a transporting conveyor having endless transporting belts provided in parallel relationship, the feeding end thereof being engaged with the discharging end of the erecting conveyor so that the boards or the stacks thereof in the raised-up position on the transporting surface of the erecting conveyor may be received and transferred in said raised position, said transporting belts containing board reclining supports fixed thereto, said reclining supports comprising an object supporting member slightly inclined towards the direction of transportation, a reversing gear having a fork-shape board erecting and aligning base, and a fork-shape board piling-up stand connected thereto so as to form an L-shape reversing gear, said reversing gear being rotatably connected to the discharge end of the transporting conveyor at the point where the board erecting base connects with the board piling-up stand, said board erecting and aligning base being arranged with the transporting conveyor so that the boards or the stacks of boards being transported to the discharging end of the transporting conveyor may be scooped up and rotated approximately 90* to stack the boards on the piling-up stand and a discharge conveyor having endless transporting belt, the feeding ends of said transporting belt being engaged with the discharging end of the transporting conveyor so that the boards stacked by the reversing gear may be received and transported, said board piling-up base and said discharge conveyor being in parallel relationship so that the board piling-up base may be recessed below the face of the discharge conveyor.

Claim 9

An apparatus for stacking boards which are successively fed to said apparatus individually or in small stacks and in a flat position which comprises a feeding conveyor including a roller conveyor capable of feeding the boards or stacks of boards as they are lying in said flat position, an erecting conveyor on which the boards are erected including endless transporting belts provided in parallel relationship, said transporting belts containing transporting faces which are downwardly inclined, one end of said belt being disposed under the discharge end of the feeding conveyor so that the individual boards or small stacks thereof may be raised by dropping from the feeding conveyor onto the erecting conveyor, a transporting conveyor having endless transporting belts provided in parallel relationship, the feeding end thereof being engaged with the discharging end of the erecting conveyor so that the boards or the stacks thereof in the raised-up position on the transporting surface of the erecting conveyor may be received and transferred in said raised position, said transporting belts containing board reclining supports fixed thereto, said reclining supports comprising an object supporting member slightly inclined towards the direction of transportation, a reversing gear having a fork-shape board erecting and aligning base, and a fork-shape board piling-up stand connected thereto so as to form an L-shape reversing gear, said reversing gear being rotatably connected to the discharge end of the transporting conveyor at the point where the board erecting base connects with the board piling-up stand, said board erecting and aligning base being arranged with the transporting conveyor so that the boards or the stacks of boards being transported to the discharging end of the transporting conveyor may be scooped up and rotated approximately 90* to stack the boards on the piling-up stand and a discharge conveyor having endless transporting belt, the feeding ends of said transporting belt being engaged with the discharging end of the transporting conveyor so that the boards stacked by the reversing gear may be received and transported, said board piling-up base and said discharge conveyor being in parallel relationship so that the board piling-up base may be recessed below the face of the discharge conveyor.
