Spühl FTA 220 Transfer machine

FTA-220 / LF1C-220 Transfer Machine Fully automatic manufacture of spring interiors from coils of wire For Bonnell, Offset, and LFK springs High operator user-friendly and input options for optimum functions A Noise-insulating housing meets all safety regulations The machine functions are input via a PLC control. This is done on the operating panel. The screen dialog facilitates entry. The control is pre- configured to be optionally equipped with the SPÜHL TelePac remote diagnosis via a modem, which only requires a telephone connection in the vicinity of the machine. A printer connection is also possible. High Flexibility Adjustable centering pieces/bending tools for rapid switching to dif- ferent spring end coil diameters. Additional left helical loop fixtures and horizontally movable transfer arms make rapid changeover to various spring unit widths possible. The spring unit width and length as well as the number of springs per unit are entered on the operating panel. Efficiency The ability to adapt the desired production speed to the spring shape and wire gauge through continuous setting permits minimum downtime and results in higher efficiency. Automatic spring transfer makes the optimum utilization of the high production output of the automatic positioning unit where they are brought into correct spring coiling machine possible. Depending on spring size and wire position with precise spacing and with respect to the gauge, up to approximately 40,000 springs can be processed per shift. knots of the end coil. A sensor detects the presence When the width of the spring unit allows, it is optionally possible to of the passing springs. If a spring is absent, the coil- ing machine is automatically stopped. manufacture two units simultaneously with right and left side helical feed. This results in substantially greater production output cannot be used for the Offset and Cosiflex spring type. High Flexibility and Safety The SPÜHL quality assurance system, certified under ISO 9001: 2000/ ISO 14001: 1996, and stringent compliance with all relevant safety regulations ensure that the flawlessly documented, functional machine can be operated safely at all times. This also applies to the safety and noise-insulating housing and the emergency switches at all important locations. A flashing warning light is visible from a distance when malfunctions occur in the entire system. Consistent Production Quality The production process is fully automatic and the processes interact fluidly with smooth and precise movements. There are no manual interventions during production. The result is high reproducibility and consistent quality of the end product. Ease of Operation and Maintenance A microprocessor-controlled production sequence.

Optimum vertical position. Since the spacing of the inserted springs is not the same as the assembly jaws, the access to all movable parts necessary for the setting operations. The grapplers are accordingly aligned with the position of settings can be made in inching mode.

Optimize efficiency machine for the automatic production of spring interiors The FTA-220 / LFK-220 transfer machine is the optimum production machine for manufacturing large numbers of spring interiors. It combines all operations in one compact unit without manual intervention in the production process. The operator is only responsible for monitoring activities and can control several transfer machines at the same time.

The transfer machine is made up of the following system components:

F-210 automatic spring coiling machine

Spring transfer unit for linkage to the assembly machine

AM-215 assembly machine
