SVL 4H/4A is extremely simple to use and highly flexible: the operation of the system can in any case be controlled by a single operator (from the loading station of the SM 4H welding machine), while all information about the machining process (data about the frames and the types of profiles machined) can be displayed on any interface connected to the line. The serial connection enables the necessary data to be shared and machining process data to be sent and/or collected from a single workstation. These interfaces use advanced graphical solutions thus improving man- machine communication and comprehension of the information.
SM 4H welding machine can also provide software automatic control of the welding bead size (from 0.2 to 2mm) thanks to a digital adjustment system controlling the welding cycle. SM 4H, in combination with counterblocks using Seamless technology, allows obtaining a perfect seamless welding. Precision is ensured thanks to the handling of PVC profiles with controlled axes. Such system allows reducing and significantly simplifying the next machining cycle, with major benefits in terms of production rate and obtained quality.
Design of interconnection between the central unit and the welding heads is based on the use of a field bus. Such solution allows remote control and supervision directly on the operating units. Thus it is possible to implement wiring which is both very simple and accessible to ensure quick and ready accessibility for maintenance thanks to an efficient network of communication between the various mechanical, pneumatic and electronic components of the machine.
The precision guaranteed by Someco in the PVC corner cleaning machines is obtained through the use of an N/C stop that allows the frame to be positioned in the machine by making reference to the internal corner of the frame. This ensures accurate centering and no limitations due to any difference in width of the profiles making up the frame. In such solution, efficient clamping of the corner is through the independent action of two clamping systems (horizontal and vertical) mounted on two slides. As these slides move along two perpendicular directions, they refer the corner to the machine working direction.
The objective of concentrating all the frame handling functions in a device that ensures highly dynamic positioning phases and accurate positioning of the product in all phases of the work cycle has been achieved thanks to the 4- axis manipulator. Such system is independent from the actual corner cleaning machine where the tools for the cleaning cycle are located. As the device has controlled axes, the product feed, rotation and unloading cycle parameters are optimized automatically by the CNC in relation to the dimensions and weight of the frame to be handled, thus ensuring minimum cycle time with maximum accuracy and care of the surfaces in contact with the machine.
