ABSTRACT:
This invention relates to an apparatus for machining vertical panels, and in particular to vertical panel saws.
BACKGROUND
Vertical panel saws are used to cut large panels, for example four meters by two meters, into pieces shaped and dimensioned for specific purposes. A typical use might be to cut plastics or coated panels for use as kitchen worktops.
To conserve floor area in the factory or workshop, panels of this size are often cut when standing on one edge, i.e. with the panel in a vertical or near vertical plane, and it has been common practice to locate the panel on rollers to make it easier to feed the panel past a vertically adjustable circular saw to make horizontal cuts or to locate the panel correctly for a vertical cut. As these panels are heavy and awkward to Move, even on rollers, considerable manual labour is still involved in moving the panels. More important, however is the fact that cutting, for example, a four meter panel requires four meters of clear space on either side of the saw or, a total of eight meters. This amount of space is not always readily available.
It is an object of the present invention to provide an apparatus for machining vertical panels that obviates or mitigates these problems.
SUMMARY
The present invention is an apparatus for machining vertical panels, the apparatus comprising a frame for supporting a panel in a substantially vertical plane, a tool mount, and a mechanism supporting the tool mount for movement in two directions over the panel plane, the tool mount having an axis about which a tool on the mount can be rotated to change its orientation relative to the panel plane.
The mount may have a second axis about which the tool on the mount can be rotated to change its inclination relative to the panel plane.
Preferably one of the axes is perpendicular to the plane and the other axis is parallel to the plane.
A tool on the mount may be movable towards and away from the panel plane.
The frame may include a member and means for adjusting the inclination of the member to the horizontal, the mount including means for engaging the member to guide movement of the mount.
Preferably two such members are provided, one spanning the horizontal edges of the panel plane and the other spanning the vertical edges of the panel plane.
The present invention is also apparatus as defined in any of the last six preceding paragraphs in which a tool is mounted on the tool mount.
Preferably the tool is a circular saw.
