DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a device for machining panels. More particularly, the invention relates to a device for machining wood-based material panels in a substantially horizontal position.
2. Description of the Prior Art
In the construction field there is a need for machining panels, such as wood-based material panels, effectively (i.e. with sufficient accuracy and speed). Where machining involves cutting the panel to size (i.e. making it available with the desired dimensions and cut-outs), it is not unusual for suction devices in horizontal machining, (i.e. with the panel located flat) to fail to satisfy the requirements on the effectiveness in machining. This drawback is especially evident when the suction device is a component of an overall system in which sufficient cut-to-size panels always need to be available for further working.
SUMMARY OF THE INVENTION
The invention is accordingly based on the object of providing a device which permits effective panel machining and obviates the aforementioned disadvantages. It is therefore an object of the invention not only to make it possible to furnish the panels with sufficient accuracy in as short a time as possible, but also to enable the device to be integrated in an overall system producing components of single panels fully and automatically.
In accordance with the invention a device for machining panels in a substantially horizontal position comprises a carousel for mounting machining tools wherein said carousel is capable of being rotated and tilted; a sawing device mountable to said carousel wherein said sawing device comprises at least one sawing tool; a shaping device mountable to said carousel wherein said shaping device comprises at least one shaping tool.
In order to facilitate rotation of the carousel the device further comprises a worm wheel surrounding said carousel; a worm shaft connected to said worm wheel; and a motor connected to said worm shaft wherein said rotatable position of said carousel is determined by said motor driving said worm shaft which engages said worm wheel so as to rotate said carousel.
Panels can be cut by either the sawing device or the shaping device.
In order to facilitate automation of the invention the movement of said sawing device or said shaping device can be controlled by a computer. The computer can be programmed using a Computer Aided Design (CAD) Program to control the movement of the sawing device or the shaping device. The movement of said sawing device or said shaping device can be defined by a system of coordinates with the first direction parallel to said panel being defined as an x direction, the second direction parallel to said panel and perpendicular to said x direction being defined as a y direction, and a third direction perpendicular to said panel being defined as a z direction; dictated by: a starting point of a cutting line which is an A parameter defined in said x direction and said y direction; an ending point of said cutting line which is an E parameter defined in said x direction and said y direction; and a point normal to said panel which is a z parameter defined in said x direction, said y direction, and said z direction. Another parameter T can be defined as a cutting depth perpendicular to said cutting line.
The device can further comprise a translation frame parallel to an xy plane defined by said panel wherein said sawing device or shaping device is capable of being moved along said translation frame parallel to said xy plane defined by said panel.
In order to provide more stability in the device the device can also have a supporting frame; a mounting frame connected to said supporting frame and defining a mounting surface; and said translation frame being connected to said supporting frame and being capable of being moved along said supporting frame. The mounting surface further comprises a plurality of line-type mounting elements. These mounting elements can be used for remounting panels having a large surface area squarely on
