DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a device for machining plate-like workpieces, eg. furniture components, doors or windows, as well as battens or timber strips, consisting of continuously-driven lower endless chain belts, which carry the workpieces, also continuously-driven upper endless chain belts, which act on the workpieces from above, as well as of machining devices for the workpieces, arranged alongside these conveyors.
The machining devices comprise saws, mortisers, edge-gluers or similar. For machining the edges of a workpiece, a complicated manipulation of this workpiece is necessary.
SUMMARY OF THE INVENTION
The invention is based on the object of improving the device explained at the start with respect to the manipulation of the workpieces.
This object is achieved according to the invention by the following features: comprising respectively upper and lower chain belts, arranged with a clearance between them and driven in opposite directions of travel; corresponding upper chain belts and form at this point an input or output region for the workpieces; opposite input region of the second conveyor unit are roller tracks or similar which operate transversely to the direction of travel of the conveyor units, said tracks being able to be raised above the lower chain belt as well as being able to be lowered between the lower chain belts, and being linked together by a transverse conveyor; comprises all the machining devices of the two conveyor units.
It is advantageous here if there are in the input region of the first conveyor unit as well as in the output region of the second conveyor unit, roller tracks or similar which operate transversely to the direction of travel of the conveyor units, said tracks being able to be raised above the lower chain belt as well as being able to be lowered between the lower chain belts.
The number and spacing of the alower chain belts correspond to the workpiece dimensions to be machined. To take over the workpiece, the lower chain belts are extended beyond the upper chain belt. The upper chain belt can in each case be designed as a double chain belt, the spacing of which is determined by the smallest workpiece width. In addition, the upper chain belts can be provided with a soundproof cover.
In order to ensure a continuous workpiece transport, it is advantageous if the lower and upper chain belts of each conveyor unit are driven synchronously via direct-current geared motors.
For positioning of the workpieces upon entering into the second conveyor unit, it is advantageous if at least one positioning backrest for the workpieces, which is adjustable in the direction of travel of the transverse conveyor, is arranged in the input region of the second conveyor unit. If there are large differences in length between the workpieces to be machined, it is advantageous if several such positioning backrests are provided.
The raisable and lowerable roller tracks can also be substituted by other conveying devices acting in a similar manner. The cyclic control of the raising and lowering movements of the roller tracks is likewise performed from the machining cell, which can be surrounded by a soundproof case and, apart from all the necessary machining devices of the two conveyor units, also comprises the controls for the roller tracks as well as the positioning backrest and for the straightline control.
The machining center according to the invention is suitable for longitudinal and transverse machining, the workpieces, which first pass in longitudinal direction through the two conveyor units, subsequently being introduced once again in transverse direction into the device, if all four edges of the plate-shaped workpiece have to be machined. Production is independent of length and can be carried out continuously, to be precise in small batch production and in single piece production. There are no changeover times in cases of a change in length. Assembly-related production (consignment production) is possible. Only one person is necessary for operation of the e
