Automation System SpeedLine INDIVIDUAL
With the SpeedLine crimping machines, Schäfer offers innovative swivel arm wire processing machines for high productivity and diverse applications. The modular platform was developed for different machine variants to provide maximum flexibility for customer-specific requirements. Minimal machine downtime, ergonomic working heights, and the safety concept were the main focus. The machine variants are divided into standard models for typical applications and custom configurations for complex solutions. This crimping machine falls into the standard models category and offers equipment for typical cable productions with up to 4 stations. Various machine configurations can be selected from additional options to achieve reproducible and complex cable processing. To ensure product quality, Schäfer offers optional extensions. The crimp force monitoring module reliably evaluates the quality of crimp connections. The conductor quality monitoring reports defective parts due to faulty stripping, and the optical cable quality monitoring inspects the produced cables. The WireStar HMI software supports optimum process sequences through its user-friendly operator interface and constant data availability from previous productions. Interaction via the modern user interface is done via a touchscreen and offers a safe handling of the machine. WireStar‘s excellent networkability contributes to central process coordination and supports through extensive and configurable database management. The integrated networking with Schäfer Connect facilitates process coordination with the operator‘s planning system for resources (e.g. ERP). The dashboard can also be used to display status, production progress and material consumption independent of the installation location.
Automation System SynchroLine
The high-performance wire processing machine is used for the production of high quality cables for medicine applications. On the prepared wires, crimp connections are manufactured with high precision and special connectors are applied. Schäfer has many years of experience in the development and manufacture of tools and machines for the processing of individual wires. The basis of the fully automatic cable processing machine is a transfer system which transports the wires to the respective stations with shuttles. The two core wire is fed nearly tension-free by means of a specially developed wire unwinder. Depending on demand, the speed of the unwinding is controlled and a corresponding length of fiber is stored in a buffer. The product-dependent wire lengths are cut at the first station of the processing machine. The control system with touch screen has an intuitive user interface for easy and safe operation of the machine in different languages. The selection of different user roles and operating modes as well as machine networking functions enable flexible and modern process sequences.
Crimping Machine PlugLine 345-3 EXTENDED
The high-performance crimping machine is designed for the economical production of high quality power cables. Crimp connections are made between two- or three-core sheathed cables and power plugs. The closed insertion mask and colour detection supports the correct feeding of the cables by the machine operator. The cables are fed manually, cut to a reference length and stripped. A vacuum system removes insulation and wire residues from the process area. In the cable processing machine, the loose power plugs are positioned with a spiral conveyor. The components to be connected are automatically fed to the crimping process via a conveyor rail. The safety of the operator during processing is ensured by closed protective covers. A column guided crimping applicator connects the sheathed cables with the power plugs. The optional crimp force monitoring system with bad part cutter prevents the use of cables with incorrect crimps in the further process and provides the quality assurance. With a production rate of up to 1450 pieces per hour the crimping machine is ideal for series production. The high grade components, the robust machine design and the modular structure stand for highest product quality, short set-up times and durability.
