Device for producing packaging comprising an independent mandrel wheel drive
Shown and described is a device for producing packaging, in particular for processing package sleeves, comprising: a mandrel wheel with a mandrel wheel shaft with a central axis, a plurality of mandrels fastened to the mandrel wheel shaft, wherein the mandrels form at least one mandrel group, whose mandrels are arranged in a plane perpendicular to the central axis of the mandrel wheel shaft, at least one first processing station which is arranged on the mandrel wheel and comprises a drive, and a mandrel wheel drive to drive the mandrel wheel shaft. In order to facilitate a particular flexible mode of driving the device, it is proposed that the mandrel wheel drive is mechanically uncouple from the drive the at least one processing station.
1. A device for producing packaging comprising:
a mandrel wheel with a mandrel wheel shaft with a central axis,
a plurality of mandrels fastened to the mandrel wheel shaft, the plurality of mandrels forming at least one mandrel group, whose mandrels are arranged in a plane perpendicular to the central axis of the mandrel wheel shaft,
a first processing station which is arranged on the mandrel wheel and comprising a drive,
a second processing station which is arranged on the mandrel wheel and comprising a drive independent from the drive of the first processing station,
wherein one of the processing stations is a press and one of the processing stations is a folding device, and
a mandrel wheel drive to drive the mandrel wheel shaft,
wherein the mandrel wheel drive is mechanically uncoupled and independent from the two independent drives of the first and second processing stations,
wherein:
i) a drive unit is used as the drive of at least one of the first and second processing stations, the drive unit comprising an electric motor, a transmission, and a controller or
ii) a direct drive is used as the drive of at least one of the first and second processing stations, the direct drive comprising an electric motor having no separate transmission and a controller,
wherein in the controller, at least one time course of a moment of inertia is stored, and
wherein a position regulation of the electric motor takes place by torque pre-control of the time course of the moment of inertia stored in the controller.
