The Frame Fitting Center points the way to the fully automatic final assembly of windows. Beside a high flexibility in manufacturing this plant offers highest precision and optimal time management at the same time. All works which are necessary for mounting the frame hardware – e.g. first drilling, setting and screwing – are done at the finished frame fully automatically and with highest precision. Expensive manual mounting on unwieldy frames, as well as mounting faults become unnecessary.
The plant has separate mounting heads for mounting the keeper and mounting the bearings for sash hinges. These mounting heads are equipped with several drilling and screwing units which work independently.
Hoppers (insert or feed hoppers) or oscillating conveyors are used to place the mounting frames. The hoppers are tipped according to the parts and outside the safety stop. So the operator’s work is simplified very much. During the processing of the current frame the control system takes over the part data from the offset plant for the following frame which has to be processed. Thus the gathering of information and the supply of all lock furniture for the next frame processing is done in one cycle before the actual mounting.
The automatic can feed frames of different sizes professionally on horizontal and vertical legs with lock furniture. The processing of door frames and crosses goes without saying. The theoretically maximum number of panels is 99 panels.
The hoppers can alternatively be arranged before or behind the machine. As standard the plant can process maximally 4 different bearings and 12 different keepers.
The plant sets all the necessary lock furniture on the frame, e.g. keepers, leading supports, balcony door latch bolts, automatic lock, corner bearings, shearing bearings.
High-exact NC placing facilities ensure the exact delivery of all processing points at the frame. After delivering the positions of the grooves the parts are mounted and all necessary processes such as first drilling, setting and screwing up the mounting frames. The delivery of different screwing appliances to the mounting places is done by servo control.
This fittings mounting centre mounts and bolts all closure components on the detached bar. The machine is best positioned immediately after the bar cutting. The system can thus be easily integrated into a LEMUTH unicut 200 cutting and machining centre. This configuration can also be used as a standalone system. The user-friendly provisioning of the closure components is carried out via feed magazines and oscillating conveyors.
