Abstract

A container treatment plant and a method for displacing an element of a valve or a diverting unit of a container treatment plant. The container treatment plant comprises at least one element for treating containers. The element is part of a valve or a diverting unit. The container treatment plant also comprises a displacing unit for displacing the element between a first position and a second position, wherein the displacing unit comprises a magnetically operating actuator such that a rotary motion caused by the actuator displaces the element with the aid of a mechanism between its first and second positions.

First claim

What is claimed is:

1. A container treatment plant comprising:
at least one element for treating containers, wherein the element is part of a valve; and
a displacing unit for displacing the element between a first position and a second position,
wherein the displacing unit comprises a magnetically operating actuator such that a rotary motion caused by the actuator displaces the element with the aid of a mechanism between a first position and a second position,
and wherein the valve is a valve selected from the group consisting of a filling valve of a filling unit for filling at least one medium in a container and a blowing valve of a stretch blow molding machine.

2. The container treatment plant according to claim 1 , wherein the mechanism is configured such that a rotary motion caused by the actuator is transformed into a linear motion between the first and second positions.

3. The container treatment plant according to claim 1 , wherein the valve comprises a deflectable rod which is coupled in such a way with a rotor of the actuator and a guiding rod that a rotary motion caused by the actuator is transformed into a linear motion of the guiding rod, or
wherein the valve has a tubular piston comprising an external indentation which is coupled with an inner indentation of the actuator such that a rotary motion caused by the actuator is transformed into a linear motion of the tubular piston.

4. The container treatment plant according to claim 3 ,
wherein the external indentation is implemented as a threaded rod, and/or
wherein the external indentation and the inner indentation form a transmission that is implemented self-locking and/or the play thereof is adjustable.

5. The container treatment plant according to claim 3 , wherein the tubular piston is a tubular piston which is equilibrated as regards pressure and/or
wherein the tubular piston comprises a rotation protection against rotating around its own axis.

6. The container treatment plant according to claim 3 , wherein an electric control unit for controlling the actuator is integrated into the valve.

7. The container treatment plant according to claim 3 , wherein the valve comprises a housing which comprises a housing cover and which is sealed against a pressure of up to approximately 40 bar and in which the displacing unit is mounted.

8. The container treatment plant according to claim 1 , wherein the actuator is a 4-pole direct current actuator which is operable with magnetism between two positions.

9. A method for displacing an element of a valve or a diverting unit of a container treatment plant which comprises at least one element for treating containers, wherein the element is part of the valve or the diverting unit, wherein the method comprises the step of:
displacing, by a displacing unit, of the element between a first position and a second position;
wherein the displacing unit comprises a magnetically operating actuator such that a rotary motion caused by the actuator displaces the element with the aid of a mechanism between a first position and a second position,
and wherein the valve is one selected from the group consisting of a filling valve of a filling unit for filling at least one medium in a container and a blowing valve of a stretch blow molding machine.

10. A container treatment plant comprising:
at least one element for treating containers, wherein the at least one element is part of a diverting unit; and
a displacing unit for displacing the at least one element between a first position and a second position,
wherein the displacing unit comprises a magnetically operating actuator such that a rotary motion caused by the actuator displaces the element with the aid of a mechanism between a first position and a second position
wherein a plurality of diverting units are arranged in one row side by side to each other, and
wherein a cam disc drivable by the actuator is positioned in such a way relative to the row of diverting units that a rotation of the cam disc around an axis of the cam disc causes, by a rotation of the actuator, that every cam of the cam disc one after the other touches one of the diverting units and transfers the diverting unit corresponding therewith into a linear motion, to move the diverting unit from the first position into the second position.

11. The container treatment plant according to claim 10 , wherein the mechanism is configured such that a rotary motion caused by the actuator is transformed into a linear motion between the first and second positions.

12. The container treatment plant according to claim 10 , wherein the actuator is a 4-pole direct current actuator which is operable with magnetism between two positions.

13. The container treatment plant according to claim 10 , further comprising a control unit for controlling the actuator, wherein said actuator has a rotor, such that said rotor accelerates starting from a working point and that the actuator is switched to a currentless state when approaching another working point, so that the rotor sweeps through said another working point due to the mass inertia of the rotor or the mass inertia of a mounted load and then the rotor can be operated again by a voltage reversal in the same direction as before to achieve a discrete true running of the actuator around an axis of the actuator.

14. The container treatment plant according to claim 10 , wherein the at least one element is part of a transport star for transporting containers and/or a pusher and/or is part of a goad aggregate and/or part of a labeling carrier and/or part of a diverting turnout.
