Abstract
An automatic planing machine has two feed rollers on one side of the machine and a stool for holding two pressure rollers which are pressed toward the feed rollers with a pressure force smaller than a pressure force of the feed rollers. The machine has a compact driving mechanism for rotating the feed rollers and further has a feed mechanism for move the stool and a casing for holding the feed rollers toward and away from each together with back-lash preventing means.
Claims11
An automatic planing machine for cutting a workpiece, which comprises:
- a) a cutter block for cutting one side of the workpiece;
- b) at least one feed roller located beside the cutter block for feeding the workpiece in one direction;
- c) a table disposed opposite to the cutter block for guiding the workpiece;
- and
- d) at least one pressure member disposed opposite to the feed roller so as to project from and retract into the table, the pressure member pushing the workpiece toward the feed roller with a pressure force smaller than a pressure force generated by the feed roller for pressing the workpiece onto the table.
An automatic planing machine for cutting a workpiece, which comprises:
- a) a cutter block for cutting one side of the of the workpiece;
- b) at least one feed roller located beside the cutter block for feeding the workpiece in one direction;
- c) a table disposed opposite to the cutter block for guiding the workpiece;
- and
- d) a driving mechanism for rotating the feed roller including a power source, a driving force transmission member disposed between the power source and the cutter block for transmitting the driving force of the power source to the cutter block, a reduction gear train disposed between the cutter block and the feed roller for transmitting rotation of the cutter block to the feed roller and a gear case for accommodating the reduction gear train therein.
An automatic planing machine for cutting a workpiece, which comprises:
- a) a cutter block for cutting the workpiece on one side;
- b) at least one feed roller located beside the cutter block for feeding the workpiece in one direction;
- c) a table disposed opposite to the cutter block for guiding the workpiece;
- d) at least one feed screw for moving the table;
- e) a casing for holding the feed roller, one of the table and the casing being fixed the other thereof being capable of moving;
- f) at least one plate spring disposed between the casing and the feed screw for eliminating back-lash between the casing and the feed screw;
- and
- g) at least one nut disposed between the table and the feed screw for eliminating back-lash between the casing and the feed screw.
