Active sawguide assembly and method
View Patent ↗A sawguide assembly includes a plurality of sets of sawguides, the sawguides within each set positioned adjacent to one another to create an array of laterally-abutting sawguides. Corresponding sawguide biasing assemblies bias the sawguides in each set against one another. The arrays are supported for independent movement along a lateral path generally parallel to the axis of the arbor. Lateral drivers are used to move each array in unison along the lateral path but independent of the other arrays. A sawguide array skewing assembly couples the sawguides of each array to one another so that the sawguides can be pivoted in unison about their respective pivot axes by a corresponding skewing driver.
1. An active sawguide assembly, used to position a plurality of saws along a saw drive arbor, comprising:
a set of sawguides mounted to one another to create an array of sawguides having laterally-abutting lateral sides;
means for laterally translating said array along a lateral path; and
means for simultaneously pivoting each said sawguide about its own sawguide axis so that said lateral sides slide over one another, wherein said set of sawguides is a plurality of sets of sawguides, and wherein sawguides within each set of sawguides within said plurality of sets of sawguides are positioned adjacent to one another to create separate arrays of laterally-abutting sawguides, each array of said separate arrays corresponding to a set of said plurality of sets of sawguides, said assembly further comprising:
(a) sawguide biasing assemblies for biasing each sawguides in each said set against one another;
(b) for each said array a sawguide array skewing assembly coupling said sawguides of each said array to one another and pivoting within said array said sawguides in unison about their respective pivot axes.
wherein said means for laterally translating said array includes lateral driving means to move each said array independently of other said arrays in said separate arrays along a lateral path relative to a workpiece infeed direction.
2. The assembly of claim 1 wherein said skewing assembly includes skewing drivers operatively coupled to said arrays.
3. The device of claim 1 wherein said set of sawguides includes first and second sets of sawguides, said first set of sawguides mounted to one another to create a first array of sawguides having laterally-abutting sides, said second set of sawguides mounted to one another to create a second array of sawguides having laterally abutting sides; and,
wherein said lateral driving means includes means for independently selectively translating said first and second arrays along said lateral path.
