Apparatus for producing bag packages filled with a product

Abstract

An apparatus for producing bag packages filled with a product has a tubular-bag-making machine, in which the bag packages are produced. After that, the bag packages reach a weighing device and from there they reach a conveyor system, which delivers the bag packages to downstream evacuating and closing systems. Because the weighing device is disposed between the tubular-bag-making machine and the conveyor system, it is possible to ascertain the current weight of a bag package that has just been filled, and if the weight deviates from a rated filling weight, it is possible to trigger the metering device of the tubular-bag-making machine in such a way that the next bag package filled contains the rated filling quantity again.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to an apparatus for producing tubular bag packages filled with a product. [0003] 2. Description of the Prior Art [0004] Apparatuses are already known which have a tubular-bag-making machine and the tubular-bag-making machine produces bags that are filled with a product inside the tubular-bag-making machine. The thus-filled bag packages, which are not yet sealed in their top region, are spun off from the tubular-bag-making machine into a packaged goods chain. The packaged goods chain, driven in clocked fashion, then conveys the bag packages into the region of a weighing device, where the bag packages to be weighed can be weighed by being released from the packaged goods chain. If a rated weight is undershot or exceeded, the metering device in the tubular-bag-making machine is then triggered accordingly. A disadvantage of the known apparatus is that releasing the bag packages in the region of the...

Benefits of technology

[0005] The apparatus according to the invention for producing bag packages filled with a product has the advantage that it enables the shortest possible controlled system between the weighing device and the metering device in the tubular-bag-making machine; thus if the just-weighed bag package deviates from the rated weight, the next bag package already contains the correct rated weight. Moreover, it is possible to dispense with an exemption device in the conveyor system for the bag packages. Remetering units that are otherwise sometimes necessary are also superfluous. Thus the number of bag packages produced in the apparatus but provided with the wrong weight is very low. At the same time, a relatively simple layout of the apparatus is possible. According to the invention, this is achieved essentially by providing that the weighing device is disposed in the transfer region between the tubular-bag-making machine and the conveyor system for the bag packages.

[0006] Advantageous refinements of the apparatus of the invention for producing product-filled bag packages are disclosed. In one advantageous embodiment, the weighing cup for receiving the bag package below the transverse seam cutter is aligned with the tubular-bag-making machine in such a way that the bag package drops into the weighing cup by its own weight. As a result, additional transfer devices, which would possibly also adversely affect the cycling times, can be avoided. It is also especially advantageous if the weighing cup has a movable bottom, so that the bag package, after being weighed, can be transferred simply and directly (by the force of its weight) into the conveyor system, especially when the weighing cup is still aligned with the receptacle in the conveyor system. To enable easy and simple adaptation of the apparatus to various bag packages or bag package formats, the weighing cup is embodied as a format-dependent component, which is secured replaceably to a weighing block.
