Problems solved by technology

However, due to the very complex transmission systems used in many cases and, in the case of turntables, sometimes even several servo motors for the drive, misalignment can occur, especially due to gear backlash
This makes it difficult to meet the high precision requirements especially during the labeling and printing of containers
Furthermore, the lubrication of the bearings in which the turntable is guided and of the toothed connections is very complex and requires a large installation space for accommodating the entire drive system

Embodiment Construction

[0028] Figure 1a A rotary machine 100 according to the invention is shown. It includes a fixed part 101 and a rotating part 102 . Typically, container handling stations or container gripping stations or elements for securing the containers or container transport elements are arranged on the rotary section 102 . Depending on the embodiment of the rotary machine 100, these can vary widely. As an example, the rotary section in a direct printer includes several container handling stations or container gripping stations. The latter may, for example, comprise respective carousels and printing modules associated therewith. Depending on the design of the rotary machine, other components such as ink tanks, labeling or printing units, etc. can be arranged at the fixed part 101 of the rotary machine. Here, various different embodiments are known which may depend on the type of container handling machine.

[0029] Basically, the fixed part 101 and the rotating part 102 are interconn...

Abstract

Rotary machine, in particular container treatment machine, including a rotating part which has several treatment stations, and a stationary part, the rotating part and the stationary part are embodied such that they together form the drive of the machine, the rotating part forming the rotor and the stationary part forming the stator of an electric motor.

Description

technical field [0001] The invention relates to a rotary machine, in particular to the drive of the rotary machine. Background technique [0002] Rotary machines, such as those in the beverage processing industry, are well known. For example, there are stretch blow molding machines or labeling machines and direct printers for processing containers which are embodied as rotary machines and can thus be operated continuously and / or discontinuously. The connection between the turning parts or rotating parts of each turning machine is usually realized by a ball bearing slewing rim. The ball-bearing swivel chassis includes toothings so that, for example, a connection can be established via a pinion to a servomotor, which will then drive the corresponding carousel. However, since in many cases very complex transmission systems are used, and in the case of turntables sometimes even several servo motors are provided for the drive, misalignments can occur, especially due to gear bac...
