Patent number: 8613585Abstract: The invention concerns a method and an arrangement for stacking timber packages in layer that uses a transfer arrangement comprising mobile carrier planes. The carrier planes in turn form a direct continuation of an input transporter in order to receive layers fed from this transporter by being caused to lift from below a complete layer from the input transporter and displacing the layer in over the stacking table. After that, the carrier planes are withdrawn from the stacking table while the layer of timber is scraped off from the carrier plane or, the stacking table is arranged to move downwards. The transfer arrangement uses a first, a second and a third carrier plane which are arranged to move mutually in a cycle in such a manner that one pair of two consecutive carrier planes is located at the same time at a position above the stacking table.Type: GrantFiled: May 7, 2010Date of Patent: December 24, 2013Assignee: Renholmen ABInventors: Jan Johansson, Gunnar Marklund

Patent number: 8366376Abstract: This is a paper-stacking support with segmented shelves that can support paper and can also fold upon being rotated around rollers by a driver belt. Once an upper shelf is fully loaded, it is moved downwardly by the drive belt and another shelf is moved into an upper loading position by the drive belt. This allows for a continuous running of the stacking operation without an interruption during the unloading of the stacked paper.Type: GrantFiled: June 9, 2009Date of Patent: February 5, 2013Assignee: Xerox CorporationInventor: Douglas K. Herrmann

Patent number: 7811047Abstract: In one representative example an underlayment stickering stacker includes a carriage/fork device configured to move a course of material with underlaid sticks from a course forming station to a hoist device, thereby forming the stack of material. The stacker also includes a rake-off device configured to facilitate removal of the course of material from the carriage/fork device. The stacker also includes a regenerative actuator configured to provide regenerative braking power to one of the hoist device, the carriage/fork device and the rake-off device.Type: GrantFiled: August 23, 2007Date of Patent: October 12, 2010Inventors: Erik L. Humble, Charles W. Moles

Patent number: 6722844Abstract: A lumber stacking apparatus 10 is described for forming a stack 12 of layers 14 of boards with stickers placed transversely between the layers. The apparatus 10 has a reciprocating arm structure 50 for successively picking up layers from an elevated surface and moving the layers over to a stacking station where the layers are stripped from the arm structure 50 as the arm structure 50 is retracted. The arm structure 50 has lifting arms 56 with open channels 64 formed therein to receive the stickers 16. A sticker distribution conveyor 160 extends along the rear of the apparatus to distribute stickers to spaced sticker stations 164 corresponding to the lifting arms 56. A sticker transfer conveyor 170 has a sticker removal subassembly 172 for engaging rear ends of the stickers at the sticker stations 164 and pushing the stickers lengthwise toward the open arm channels 64.Type: GrantFiled: October 26, 2001Date of Patent: April 20, 2004Inventor: Sidney L. Lunden

Publication number: 20030026682Abstract: A synchronized palletizer includes a row conveyor and a layer head, each vertically reciprocating within a frame. An infeed conveyor delivers in series items row-by-row onto the row conveyor. The row conveyor moves to vertically coincide with the layer head and laterally transfer a row items onto the layer head. Once a complete item layer has been constructed on the layer head, the layer head collapses the layer together and drops the layer through its floor onto a pallet or stack of item layers therebelow. Generally, the layer head vertical position follows the top of stack of item layers and the row conveyor travels reciprocally between the infeed conveyor and the layer head to deliver items row-by-row to the layer head. A variety of alternative relative positioning schemes, however, may be implemented.Type: ApplicationFiled: August 1, 2001Publication date: February 6, 2003Inventors: Stephen L. Heston, Cary Michael Pierson

Patent number: 6241458Abstract: A stacker for stacking articles, particularly blister packs, into stacks of goods, including a goods feeder, a primary packing unit and a unit for supplying the stacks for secondary packing or processing. The packing unit has a goods magazine with a goods support, on which the articles inserted in the magazine may be deposited to form stacks of goods. The goods magazine has a first goods support and a second goods support, the first support being arranged above the stack of goods until the stack resting on the second support is removed. A further stack may be piled up on the first support and lowered into the removal position following the removal of the stack located below it.Type: GrantFiled: April 29, 1999Date of Patent: June 5, 2001Assignee: Skinetta Pac-Systeme Kiener GmbH & Co.Inventor: Ernst H. Berndl

Patent number: 6238174Abstract: A sticker transfer mechanism for a lumber stacker has a swing-away transfer arm for transferring stickers from a sticker conveyor to pans on stacking forks. An arm segment is pivotally mounted to a base section to form the swing-away transfer arm. The pivotal mounting of the arm segment permits the arm segment to pivot when encountering an obstruction.Type: GrantFiled: August 19, 1999Date of Patent: May 29, 2001Assignee: U.S. Natural ResourcesInventor: John D.
