Patent number: 10112331Abstract: A toggle lever clamping unit for an injection molding machine includes fixed and movable platens, a support plate, a toggle lever mechanism operatively connected with both the support plate and the movable platen, a cross clamp operatively connected with the toggle lever mechanism and movable along a machine longitudinal axis, and an electric drive for moving the cross clamp. In addition, a hydraulic drive is operatively connected with the cross clamp and includes a fluid-operated piston cylinder system, with the lengths of the cylinder and the piston rod being coordinated with one another such that the hydraulic drive follows a travel path of the cross clamp as the movable platen travels between an open position of the clamping unit, in which the toggle lever mechanism is swung in, and a closed position in which the toggle lever mechanism assumes a predeterminable extended position and a clamping force is built up.Type: GrantFiled: May 13, 2016Date of Patent: October 30, 2018Assignee: NETSTAL-MASCHINEN AGInventors: Adrian Angst, Martin Fuchs, Manuel Hausammann, Marcel Hautle, Daniel Jenny, Marc Lüthi, Adrain Mächler, Marco Meier, Markus Notz, Remo Schwitter

Patent number: 9229439Abstract: In a device and a method for operating a driven axle in a machine tool, in particular in an injection-molding machine, at least two different drives are coupled to form a common effective drive, wherein the performance and energy consumption data for each drive are stored in the form of characteristic values or characteristic curves. To use the effective drive as optimally as possible in terms of energy, it is proposed to determine the performance requirement for the driven axle, to determine the particular operational combination of the different drives that requires the least expenditure of energy based on the determined performance requirement and to drive the drives with the determined particular operational combination.Type: GrantFiled: June 1, 2011Date of Patent: January 5, 2016Assignee: NETSTAL-MASCHINEN AGInventor: Markus Notz

Patent number: 9156199Abstract: A hybrid drive includes an electric motor coupled to a hydraulic drive having a double-acting hydraulic piston and a piston rod, and a substantially throttle-less valve for actuating the hydraulic drive, and a control unit for actuating the electric machine. To avoid unnecessary energy consumption, an actuating direction requested by the hybrid drive and a desired actuating force are determined, the valve is switched to a position such that the hydraulic drive is effective in the actuating direction, at least when the actuating force cannot be generated by the electric motor alone, the difference between the force generated by the hydraulic drive and the actuating force is determined, and the electric motor is operated such that the desired actuating force is achieved by adding the force generated by the motor to the force generated by the hydraulic drive, or subtracting the first from the latter.Type: GrantFiled: May 9, 2011Date of Patent: October 13, 2015Assignee: NETSTAL-MASCHINEN AGInventors: Markus Notz, Markus Lanker

Patent number: 8123989Abstract: The invention relates to a method and device for controlling a linear motion axis, particularly of the injection screw (43) or a melt piston for an injection molding machine. Said device comprises a hydraulically driven piston (45) having a piston chamber (A) and a rod chamber (B). According to the solution proposed by the invention, at least one process phase is controlled/regulated by means of two parallel proportional valves, an injection valve (1) and a metering valve (2). The two proportional valves can be connected in parallel or in combination. The control/regulation of the driven piston (45) preferably uses digital technology. An enormous reduction in energy consumption and smooth transitions between the process phases are achieved with a hydraulic linear drive.Type: GrantFiled: October 16, 2008Date of Patent: February 28, 2012Assignee: Netstal Maschinen AGInventor: Markus Notz
