Problems solved by technology

[0003] A disadvantage of the known device is that the operation of the sealing device is independent of the bag used
Therefore, to date, the adoption of plastic bags in machines designed for paper bags has remained a problem

Embodiment Construction

[0034] figure 1 A schematic top view of a packaging machine 1 is shown, which is designed as a rotary filling machine and comprises a housing 3 and a total of six filling nozzles 12 which are distributed uniformly over the circumference.

[0035] and figure 1 As shown, the packaging machine 1 according to the invention may comprise a greater or lesser number of filling nozzles. In the case of a rotary configuration, it is preferred to use more than two filling nozzles, preferably 6, 8, 10, 12 or 16 filling nozzles. In addition, other different numbers are also contemplated.

[0036] in such as figure 1 In the case of the packaging machine 1 shown, a bag, in particular designed as a valve bag 13 , is placed on the filling spout 12 at the placement position B. Although manual placement is possible, placement is preferably by means of a separate automatic feeder (not shown) which deposits or pushes the valve pocket 13 onto the filling nozzle 12 .

[0037] Each filling nozzle...

Abstract

The packaging machine has a filling nozzle for filling the bags and a locking device for welding the bags. The locking device has two locking elements, which are welded between the bags. The available contact pressure is changeable between the locking elements during welding. An independent claim is also included for a method for operating a packaging machine for filling bags.

Description

technical field [0001] The invention relates to a packaging or filling machine and a method for filling bags, in particular valve bags, with bulk material. In principle, liquid or pasty materials can also be filled. The invention can be used, for example, to fill bags encased in thermoplastics. Preferred applications are bags made of or wrapped in plastic film, in particular valve bags, which are welded by sealing, especially after filling with dry bulk material, such as building material or granules. Background technique [0002] Different filling machines for closing the bags after filling are known in the prior art. The closure can be performed, for example, by means of an ultrasonic welding process. For this purpose, the laminar layers of the valve bag which cover the valve port are welded together in an ultrasonic welding device so that the bag is tightly closed. The ultrasonic welding device comprises a sonotrode or horn and an anvil extending over the entire width...
