Patent ID: 7011122

Claim:
An edge-routing unit for a program-controlled feed-through machine for machining plate-shaped workpieces ( 1 ), wherein each plate-shaped workpiece ( 1 ) has a workpiece outline, a narrow surface side ( 2 ), a workpiece surface with a contour, a feed-through direction, a longitudinal direction lying in the feed-through direction thereof, and is made of at least one of wood and wood substitutes for panels for one of furniture making and interior finishing, wherein the narrow surface side ( 2 ) of each plate-shaped workpiece ( 1 ) has thereon an edge strip ( 3 ) with a projection, and wherein the machine has a workpiece feed-through direction which is an X-axis and a workpiece thickness direction which is a Z-axis, the edge-routing unit comprising: a) a routing motor ( 6 ); b) a rest ( 10 ); c) positioning devices ( 11 , 12 ; 13 , 14 ); d) a feeler wheel ( 5 ); e) a fine-positioning slide ( 15 ); f) an X-positioning drive ( 18 ); g) a Z-positioning drive ( 19 ); and h) a routing tool ( 4 ); wherein the routing motor ( 6 ) has a shaft ( 9 ); wherein the routing tool ( 4 ) has a diameter; wherein the routing tool ( 4 ) is on the shaft ( 9 ) of the routing motor ( 6 ); wherein the routing tool ( 4 ) is arranged on the rest ( 10 ); wherein the routing tool ( 4 ) by way of the positioning devices ( 11 , 12 ; 13 , 14 ) is controlled so as to run approximately along the workpiece outline and partly with a respective workpiece over a short distance in the workpiece feed-through direction, the X-axis, and perpendicularly thereto in the workpiece thickness direction, the Z-axis; wherein the feeler wheel ( 5 ) is coaxial to the routing tool ( 4 ); wherein the feeler wheel ( 5 ) has a diameter; wherein said diameter of the feeler wheel ( 5 ) is equal to the diameter of the routing tool ( 4 ); wherein the feeler wheel ( 5 ) travels over the workpiece surface adjoining the edge strip ( 3 ); wherein the feeler wheel ( 5 ) is supported on the workpiece ( 1 ) for follow-up of the routing tool ( 4 ) according to the contour sensed by the feeler wheel ( 5 ); wherein the routing motor ( 6 ) is adjustable together with the routing tool ( 4 ) on the rest ( 10 ) relative to the feeler wheel ( 5 ); wherein the fine-positioning slide ( 15 ) is arranged on the rest ( 10 ); wherein the fine-positioning slide ( 15 ) and the routing motor ( 6 ) sit together with the routing tool ( 4 ) on the rest ( 10 ); and wherein the fine-position slide ( 15 ) is traversable in a motor-operated program-cotrolled manner relative to the rest ( 10 ) in the direction of the X-axis and in the direction of the Z-axis, for which purpose the X-positioning drive ( 18 ) and the Z-positioning drive ( 19 ) are arranged on the rest ( 10 ).
