ABSTRACT:
A vacuum assisted stick placer for (a) retrieving a spacing stick from a J-hook on a J-hook stick conveyor, whereon a first broad side of the stick is supported on the J-hook, and (b) placing the stick onto a top surface of a stack of lumber has a selectively actuable vacuum gripping device for (a) selectively applying a vacuum to the first broad side of the stick whereby the stick may be adhered to the vacuum gripping device when the vacuum gripping device is in a stick retrieving position snug beneath the first broad side of the stick supported in the J-hook, and (b) selectively removing the vacuum from the first broad side of the stick whereby the stick may be released from the vacuum gripping device, when the vacuum gripping device is in a stick placing position substantially opposed to the stick retrieving position and proximate the top surface of the stack of lumber, a first translation device for rotatably translating the vacuum gripping device in an arcuate path and a second translation device for substantially linearly translating the vacuum gripping device in a radial direction from the arcuate path, the first and second translation devices translating the vacuum gripping device between the stick retrieving position and the stick placing position, a support frame for supporting the first and second translation devices over the stack of lumber, whereby a second broad side of the stick opposed to the first broad side may be placed into contact with the top surface of the stack of lumber.
