Abstract

The invention relates to the drive of revolving bottle-filling machines having a high-mass rotor. In addition, the invention can be applied to all machines which have a central drive and the working elements of which are linked to these via mechanical energy lines, especially if one or more working elements has or have a relatively high mass moment of inertia. The aim of the invention is to reduce the wear on the mechanical driving elements of the rotor. The object on which the invention is based is to minimise the mechanical stress on the drive system of the filling machine during the braking associated with the relatively frequent stopping of the machine. The object is achieved according to the invention by the fact that a freewheeling clutch is arranged on the output side of the drive motor and that an additional rotor brake is arranged on the rotor, in the immediate vicinity of the rotor, on the rotor shaft itself in relation to the kinematic chain. The freewheeling clutch is preferably designed as a one-way roller clutch and the rotor brake as a friction brake. The advantage of the invention consists in that the drive system is to a considerable extent relieved of load, particularly in high-speed filling machines, resulting in a large reduction in the wear on the drive elements, in particular on the main reduction gear unit. <IMAGE>

Filling machine drive

The invention relates to the drive of rotating bottle filling machines with a heavily massed rotor. In addition, the invention is applicable to all machines which have a central drive and whose working organs are linked to them via mechanical energy lines especially if one or more working organs have a relatively high mass moment of inertia or exhibit.

From DEr-OS 19 36 343 a drive for a rotating Bottle filling machine known, which essentially consists of a drive motor, a control gear, a clutch-brake-Korabination and a slip clutch. This solution requires a high level of technical effort. That is why modern rotating bottle filling machines are common equipped with electric motors (direct current motors or asynchronous motors), the speed of which can be continuously adjusted. This makes it possible to achieve the required productivity of the bottle filling machine directly by setting it the corresponding engine speeds to be realized. At every stop it is necessary to stop the bottle filling machine shut down in the shortest possible time in order to remove the number of bottles still running through (mostly not of the right quality bottled or unsealed) as little as possible keep. The disadvantage here is that the dynamic stress on the mechanical transmission system is extremely high. In particular, this reduces the service life of the main reduction gear to an inadmissibly high degree. The cause lies in the fact that all drive elements at the manure stop are exposed to high mechanical loads.

The aim of the invention is to reduce the wear and tear on the mechanical drive elements of the rotor.

The invention is based on the object of the mechanical stress of the drive system of the filling machine during the

to minimize relatively frequent business stops

The object is achieved according to the invention in that a one-way clutch is arranged after the drive motor and an additional rotor brake on the rotor, on the rotor shaft itself or is arranged in the immediate vicinity of the rotor with respect to the kinematic chain. The one-way clutch is preferred as a clamping roller clutch and the rotor brake as Friction brake designed

The advantage of the invention is that the drive system is considerable, especially in the case of high-performance filling machines is relieved, whereby the wear of the drive elements, in particular the main reduction gear, is greatly minimized will·

The solution is to be explained in more detail below using an exemplary embodiment The associated drawings have the following meanings:
