Abstract

Described is an apparatus and a method with a plurality of treatment units which are arranged on a carrier rotatable about an axis of rotation and which treat the containers in a pre-set manner, wherein the carrier is driven by at least one drive device and a speed of rotation of the carrier is retarded by at least one mechanical braking device which contacts the carrier at least for a time, and wherein for a retardation of the speed of rotation of the rotatable carrier at least one valve of the braking device is switched in a variable manner by a control device connected in terms of communication to the braking device, in such a way that a flowable medium under pressure is drawn individually from or into a reservoir of the braking device on or from a braking cylinder of the braking device.

Claims

1. An apparatus for treating of containers with a plurality of treatment units which are arranged on a carrier rotatable about an axis of rotation and which treat the containers in a pre-set manner, with a drive device for driving the carrier and at least one mechanical braking device contacting the carrier at least for a time in order to retard the speed of rotation of the carrier, characterized in that the braking device has at least one valve (V1b, V2b, V1c, V2c, V1d, V1e) which is capable of being switched in a variable manner by a control device connected in terms of communication to the braking device, in such a way that a removal or supply of a flowable medium (P1, P2) under pressure from or to a reservoir of the braking device is capable of being carried out individually on or by a braking cylinder of the braking device in order to achieve a braking effect.

2. The apparatus according to claim 1, wherein the valve (V1b, V2b, V1c, V2c, V1d, V1e) is a pneumatic valve or an hydraulic valve.

3. The apparatus according to claim 1, wherein the valve (V1b, V2b, V1c, V2c, V1d) is a proportional valve (V1e).

4. The apparatus according to claim 1, wherein a plurality of braking devices are arranged at a distance from one another on an external periphery of the carrier.

5. The apparatus according to claim 1, wherein the valves (V1b, V2b, V1c, V2c, V1d, V1e) of the braking device or of a plurality of braking devices respectively are capable of being switched alternately and independently of one another.

6. The apparatus according to claim 1, wherein the braking device has at least one pre-stressed spring element for exerting a braking force.

7. The apparatus according to claim 1, wherein the drive device is a direct drive for driving the carrier.

8. The apparatus according to claim 1, wherein the drive device engages on an external periphery of the carrier.

9. A method for treating containers with a plurality of treatment units which are arranged on a carrier rotatable about an axis of rotation and which treat the containers in a pre-set manner, wherein the carrier is driven by at least one drive device and a speed of rotation of the carrier is retarded by at least one mechanical braking device which contacts the carrier at least for a time, wherein for a retardation of the speed of rotation of the rotatable carrier at least one valve (V1b, V2b, V1c, V2c, V1d, V1e) of the braking device is switched in a variable manner by a control device connected in terms of communication to the braking device, in such a way that a flowable medium (P1, P2) under pressure is drawn individually from or into a reservoir of the braking device on or from a braking cylinder of the braking device.

10. The method according to claim 9, wherein the valves (V1b, V2b, V1c, V2c, V1d, V1e) of one or more braking devices contacting the carrier are switched preferably alternately and independently of one another by the control device.

11. The method according to claim 9, wherein, when a retardation of the speed of rotation of the carrier is initiated, quantities—

of different size—

of flowable medium are supplied to or removed from individual brake cylinders of the braking devices by way of the valves (V1b, V2b, V1c, V2c, V1d, V1e) of the braking devices.

12. The method according to claim 9, wherein the valve (V1b, V2b, V1c, V2c, V1d) is a pneumatic or hydraulic proportional valve (V1e) which is switched proportionally to the stressed pressure (P1, P2).

13. The method according to claim 9, wherein the drive device acts at least for a time as an additional braking device during the retardation of the speed of rotation of the carrier.

14. The method according to claim 9, wherein, wherein the speed of rotation of the carrier is retarded completely within a rotational movement of a maximum of 270 degrees of the carrier about the axis of rotation thereof.
