Hollow glass production device with flow control

摘要

The hollow glass article-manufacturing device comprises a pressure-loadable lifting cylinder (2), a piston movable in the lifting cylinder, a functional gauge connected with the piston, and/or a flow- and flow-off line (5, 6) connecting on the lifting cylinder for a processing medium applied to the piston. The piston is movable to a glass mold stroke and a return stroke. An actuator (11) connected with the flow-off line and differently influences the flowing through barness of flow line towards its switching position. A programmable control unit (10) controls the actuator. The hollow glass article-manufacturing device comprises a pressure-loadable lifting cylinder (2), a piston movable in the lifting cylinder, a functional gauge connected with the piston, and/or a flow- and flow-off line (5, 6) connecting on the lifting cylinder for a processing medium applied to the piston. The piston is movable to a glass mold stroke and a return stroke. An actuator (11) connected with the flow-off line and differently influences the flowing through barness of flow line towards its switching position. A programmable control unit (10) controls the actuator. A pressure sensor is detectably arranged at the flow side of the medium pressure and is connected with the control unit. The control unit actuates the actuator connected with the flow line. A travel measuring unit detecting the glass mold stroke-movement is connected with the control unit in such a way that the glass mold stroke is controllably guidable in path-based and/or position-based manner. The travel measuring unit comprises an eddy current sensor for the position determination and is integratedly arranged in the lifting cylinder. The manufacturing device is arranged as pneumatic device and the processing medium is gas. The actuator is connected with the flow line and guides the process medium to the lifting cylinder in flow. The actuator is controllably connected with the control unit and is controllably operatable with another actuator at flow side in a closed control circuit. An independent claim is included for a method for hollow glass production by a flow control.
