Fragile Multihead Weigher

FRAGILE WEGER

Fragility combined with speed and accuracy

The fragile weigher has been specially developed in response to the need to weigh fragile products such as cakes and biscuits whilst minimising damage. Every multihead weigher involves drop heights, which are not a problem for many products but, in some cases, simply cause too much breakage. In the fragile weigher, all these drop distances have been minimised or replaced by a sliding motion.

For example, the feed and weighing hoppers are not positioned vertically one above the other, but are designed in such a way that a sliding motion is created from the vibrating chute. As soon as the feed hopper opens, the product lands in the weighing hopper via a sliding motion. This significantly reduces breakage compared to a conventional multihead weigher.

Once the optimal combination of weighing hoppers has been determined, the product is discharged via the slide chutes to the packaging machine. These slide chutes are designed with a very gentle 35° angle, so that little falling velocity is built up, thereby further minimising breakage. Optionally, a skirt or product stopper can also be fitted at the weigher’s outlet to reduce the impact of products colliding with one another.

With a maximum speed of 50 (10-head) to 90 (14-head) weighings per minute, there is no compromise on speed or on Combimat’s outstanding accuracy. As standard, it is possible to open the selected weighing hoppers in quick succession. This creates a longer string of product, which falls more easily through the feed hopper of the packaging machine if a narrow bag size has been selected.

Furthermore, all contact parts of the machine can be easily dismantled for cleaning, which guarantees maximum uptime of the weigher.
