Filling within seconds and reliable weighing directly into crates

The KWS crate weighing system is an ideal solution for the automatic weighing of products in Euronorm crates (600 x 400 x X mm). An existing or a supplied filling belt is controlled via the KWS for optimal filling of the crates. 

The standard equipment of the KWS includes the intake of three crates: two empty crates and the crate to be weighed. The crates are automatically guided over the sturdy weighing platform. Weight-accurate filling begins after the crate has been tared. During the filling process, the infeed belt can be controlled at two speeds: first for coarse filling and at the end of the filling process for fine filling at a slower speed. As soon as the specified (programmable) filling weight has been reached, the filled crate is automatically forwarded onto an optionally available roller conveyor with a docking station that is mechanically connected to the KWS. A new empty crate is automatically added and positioned on the weighing platform. 

The robust system is designed especially for use in automated food processing. The KWS can be optimally integrated into the process flow, in particular at the end of a production line.  

A label printer can be installed as a practical optional addition, for example for labels per crate or per pallet (after a certain number of crates).

KRONEN benefits

A slipping clutch on the drive unit ensures safety

The use of a slipping clutch on the infeed belt ensures a high level of work safety and thus considerably reduces any risk of injury. 

The infeed belt with safe belt equipment is a hygienic and reliable standard component of the crate weighing system KWS from KRONEN.

Hygienic crate transport via belts

A high-quality belt – instead of a chain – is used for transporting the containers on the infeed belt, thus offering a safe and hygienic solution.
