Abstract
An automated planer machine for planing a piece of lumber. The planer machine has a feed table for slidably receiving the bottom surface of the piece of lumber along a traveling course. One or more planing heads extend on sides of the traveling course to plane the surfaces of the piece of lumber. A linebar laterally guides the piece of lumber. Feed rolls along the traveling course move the piece of lumber. Positioning devices responsive to respective control signals are provided for adjusting a height of the feed table and planing levels of the planing heads as much when the planer machine is idle as during operation. Position encoders coupled to the feed table and the planing heads produce positional signals usable to accurately position them using the positioning devices.
Claims24
An automated planer machine for planing a piece of lumber having top, side and bottom surfaces, comprising:
- a feed table adapted to slidably receive the bottom surface of the piece of lumber along a traveling course;
- at least one planing head extending on a side of the traveling course and adapted to plane one of the surfaces of the piece of lumber;
- a linebar projecting on a side of the feed table and adapted to slidably receive one of the side surfaces of the piece of lumber;
- feed rolls extending along the traveling course and adapted to move the piece of lumber along the traveling course;
- positioning means responsive to respective control signals for adjusting a height of the feed table and a planing level of said at least one planing head with respect to said one of the surfaces of the piece of lumber according to the control signals;
- and
- position encoders respectively coupled to the feed table and said at least one planing head, for producing positional signals indicative of the height of the feed table and the planing level of said at least one planing head.
