Abstract

Abstract A chip collecting apparatus for a machine tool has two separate chip conveyors for chips of different materials. The chip collecting apparatus receives chips on fixed guide plates. Chips are washed from the fixed guide plates into a chip collecting area. In the chip collecting area is disposed a change-over plate for directing the chips from the guide plates onto either one of the chip conveyors. The change-over plate is pivotably moveable between different positions corresponding to the respective chip conveyors. In an alternative embodiment, only one chip conveyor is used, and the change-over plate is provided at the discharge end of the conveyor to discharge chips into either one of two chip collecting bins.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 175 words
A chip collecting apparatus, comprising: a frame; a fixed guide plate for receiving chips thereon provided on said frame, said fixed guide plate extending obliquely downward, and a chip falling space being defined below said fixed guide plate; a washing means disposed at an upper portion of said fixed guide plate for supplying washing liquid to the surface of said fixed guide plate for washing chips on said fixed guide plate into said chip falling space; two selectively drivable chip conveyors disposed parallel to each other at a lower portion of said chip falling space; a change-over plate having a pivot connected at a midpoint thereof pivotably disposed in said chip falling space for pivoting movement in opposite directions between a first position directing chips onto one said chip conveyor and a second position directing chips onto the other said chip conveyor; and a means for pivotably driving said change-over plate between said first and second position, said means for pivotably driving said change-over plate comprising a piston and cylinder connected to said change-over plate.
Claim 2
Dependent Claim 175 words
A chip collecting apparatus, comprising: a frame; a fixed guide plate for receiving chips thereon provided on said frame, said fixed guide plate extending obliquely downward, and a chip falling space being defined below said fixed guide plate; a washing means disposed at an upper portion of said fixed guide plate for supplying washing liquid to the surface of said fixed guide plate for washing chips on said fixed guide plate into said chip falling space; two selectively drivable chip conveyors disposed parallel to each other at a lower portion of said chip falling space; a change-over plate having a pivot connected at a midpoint thereof pivotably disposed in said chip falling space for pivoting movement in opposite directions between a first position directing chips onto one said chip conveyor and a second position directing chips onto the other said chip conveyor; and a means for pivotably driving said change-over plate between said first and second position, said means for pivotably driving said change-over plate comprising a piston and cylinder connected to said change-over plate.
Claim 3
Dependent Claim 42 words
The chip collecting apparatus as set forth in claim 1, and further comprising: a second fixed guide plate for receiving chips thereon provided on said frame, said change-over plate being pivotably disposed in said chip falling space between said fixed guide plates.
Claim 4
Dependent Claim 38 words
The chip collecting apparatus as set forth in claim 2, wherein said fixed guide plates extend longitudinally parallel to said chip conveyors, and said change-over plate extends longitudinally parallel to said chip conveyors and said fixed guide plates.
