Abstract

A machine that includes: A transportation system is disclosed for transporting panels such as wood panels between two cutting stations which cut the panels along different axes. The transportation system includes, between the cutting stations, a work surface of parallel bars. The work surface further includes three portions disposed at different levels while maintaining the bars in a parallel and aligned fashion such that a slide, also including parallel bars, may pass horizontally between the three portions. The slide operates vertically as well as horizontally to pick up the panels for transport among the three work surface portions, whose different heights permit a number of different stages of operation for the slide.

Claims

1. A panel cutting machine for cutting and transporting panels, comprising:

a) a pair of first and second work stations, the panels being transported from the first to second work station, each of the stations comprising;

1) cutting means for cutting the panels along a cutting axis, the cutting axis of one of the cutting means being positionable to be perpendicular to the cutting axis of the other cutting means;

2) a station work surface for supporting the panels in their respective stations; and

3) a pusher for feeding the panels along their respective station work surfaces and into their respective cutting means;

b) a medial work surface disposed fixedly between the station work surfaces for supporting the panels between the stations, the medial work surface comprising a set of parallel support members and being divided into first and second portions, the first and second portions being disposed at different levels; and

c) a slide adjacent to the medial work surface for picking up and transferring the panels between the first and second portions of the medial work surface without pushing the panels on the medial work surface, the slide being slidable along both horizontal and vertical axes independently and comprising a set of parallel support elements, the support elements of the slide being parallel to the support members of the medial work surface, at least some of the support elements of the slide being oriented between at least some of the support members of the medial work surface whereby the parallel support elements of the slide are slidable both horizontally and vertically through the parallel support members of the medial work surface, wherein the medial work surface further comprises a third portion having parallel support members in line with and parallel to the support members of the first and second portions, the third portion being adjacent to and at a greater height than the second portion, the slide being slidable vertically through and horizontally below each of the first, second, and third portions.

2. The machine of claim 1, wherein the cutting means, pushers, and pick up means are coordinated by an electronic control.

3. The machine of claim 1, wherein the station work surface of the first station comprises a set of parallel support bar portions parallel to the support elements of the slide, at least some of the parallel support bar portions being disposed between and adjacent to at least some of the support elements of the slide.

4. The panel cutting machine of claim 1, wherein the first portion is disposed adjacent to the first work station and the second portion is disposed adjacent to the second work station, the first portion being lower than the second portion.
