Packaging machine and method for filling pouches

Abstract

A packaging machine and method for filling bags with a supporting structure to which at least one filling box is fastened which includes a conveyor element and to which a weighing device and a filling spout are assigned. A control device is provided. The filling box is retained non-communicating with the supporting structure and the assigned filling box and is weighed separately by the assigned weighing device to discharge from the filling box a predefined quantity of intended fill product by way of differential weighing and to fill it into the bag through the tilling spout. The control device controls the strength of a volume flow into the bag over the time of the filling process so that the intended fill product is maintained at a high fill height while overflow is simultaneously prevented.

Description

technical field [0001] The invention relates to a packaging machine and method for filling bags. The packaging machine according to the invention can be used for filling a wide variety of bulk materials. However, such devices are particularly preferably used for filling fine-grained materials, ie for filling fine-grained dusty materials which require a long filling time and especially a compacting time. Background technique [0002] Various types of packaging machines for filling open-mouth bags are known in the prior art. For example, so-called FFS packaging machines ("Form-Fill-Seal packaging machines") are often used for efficient filling of bulk materials into open-mouth bags. In these FFS packaging plants the open-mouth bags are produced either within the machine or in a device immediately preceding it. The machine is equipped with a tubular film roll from which the required open-mouth bags are produced continuously during operation. The obvious advantage of these F...
