Price labelling system with high degree of protection
In its standard version, Bizerba’s fully automatic price labelling system GLM-Imaxx has already reached high degrees of protection: IP54 for the terminal and drive belts as well as IP65 for the motors and load cell.
In its standard version, Bizerba’s fully automatic price labelling system GLM-Imaxx has already reached high degrees of protection: IP54 for the terminal and drive belts as well as IP65 for the motors and load cell.
This is made possible by cable glands and special sealings on the motor. Thus, the labelling system also meets the requirements for use close to grey and white zones, in which fresh food producers aggressively clean control scales and packaging machines by using foam and hose water.
The GLM-Imaxx is originally predestined for use in the black zone, in which it comes into contact with packaged goods only. Accordingly, the cleaning regulations are moderate in this zone. “However, many fresh food producers processed meat and cheese, fruit and vegetables in large halls, in which the labelling system stands close to white zones – i.e. zones in which packaging machines and control scales are working with unpackaged products and employees are cleaning the zone aggressively by using foam and hose water,” explains Dieter Conzelmann, Director Industry Solutions at Bizerba. According to him, the engineers in Balingen had, from the start, designed the device in accordance with high protection classes in such a manner that the labelling system can also resist these difficult ambient conditions.

The IP codes indicate for which ambient conditions a device is suitable. The abbreviation stands for “Ingress Protection”. The first digit refers to foreign objects of different sizes, the second digit to water resistance. Conzelmann: “Using cable glands and special sealings, we have ensured that the terminal and the drive belts reach IP54 and are thus protected against the ingress of coarse dust and splashing water from any direction.” According to him, motors and load cell even comply with the degree of protection IP65 and are thus completely dust-tight and resistant against powerful water jets from a nozzle from any direction.
Garage for labelling unit
However, there is a problem: If employees require easy access to components - for instance, if they have to open the labelling units on a regular basis in order to change the labels -, these parts only reach the degree of protection IP20 with most producers, which means that they are not water-resistant. For this reason, each device is supplied by Bizerba with a water-tight plastic cover protecting the labelling unit. Conzelmann: “If this is not sufficient, we offer a kind of garage, a completely closed metal hood which is mounted on the applicator and into which the labelling head can be retracted during cleaning. This hood provides for an even higher level of protection.”
