Problems solved by technology

[0005] However, on the one hand, this increases the number of components that can fail in the system, and on the other hand, it also generally limits the overall throughput of the system due to the necessary throughput time caused by the measurement sensors
There is also a cost element to the additional components, and more to the installation and maintenance of the components

Embodiment Construction

[0076] figure 1 A schematic diagram of a transport system with a long stator linear motor for detecting the load of a transport element according to the invention is shown. The exemplary further development shown here shows a concrete configuration of the transport system in which the long stator 160 of the linear motor is arranged on the side of the vertically oriented secondary part (ie reaction element) 120 of the transport element 100 . However, it should be understood that the invention is not limited to this vertical configuration, but can also be applied to a horizontal configuration of the secondary section. Likewise, 120 long stators 160 can be arranged on both sides of the secondary element. Therefore, the further developments proposed here serve only to illustrate the invention and are not intended to limit the specific further developments of the long stator linear motor and transport element.

Abstract

The present invention provides a method for identifying a load and / or wear of a transport element (100) of a transport system with a long-stator linear motor (160), having the steps of: exciting (273)a dynamic system consisting of the long-stator linear motor (160) and the transport element (100) according to at least one excitation pattern; capturing (274) the movement profile of the transport element (100) on account of the at least one excitation pattern; and capturing (275) a temporal profile of a load current and / or of a load voltage of the long-stator linear motor (160) according to theat least one excitation pattern by means of an integrated measuring apparatus (180) of the long-stator linear motor; wherein a loading condition of the transport element (100) is determined (276) onthe basis of the captured movement profile and the captured temporal profile of the load current and / or of the load voltage.

Description

technical field [0001] The invention relates to a method and a device for load recognition and for detecting the loading situation of a transport element of a transport system with a long-stator linear motor. Background technique [0002] Transport systems with linear motor drives are well known in the prior art. What is common to transport systems with linear motor drives is that specially formed transport elements (so-called runners, pushers or pucks) along the transport conveyor along with one or more long stators of one or more linear motors To move, especially along one or more rails. In particular, transport elements are often used to transport objects, in particular containers, preforms or packaging, along transport conveyors. Especially in the beverage processing industry, it is often necessary to check the fill level of individual containers of containers filled with beverages or other liquids after the filling process to ensure that the deviation from the target ...
