Apparatus and method for forming, filling and sealing packaging containers each comprising one pouring device

Abstract

The invention relates to an apparatus (10) for forming, filling and sealing bags (5) each comprising one pouring device (1), having a first application device (15) for forming a hole in a flexible material web (12) and for attaching at least one part (2) of the pouring device (1) to the material web (12), a device (23) for forming a hose (25) from at least one material web (12), a filling device (28) for filling the hose (25) or the bag (5) and a cross-seam seal and separation device (33) for separating one bag (5) each from the hose (5), wherein the device (23) for forming the hose (25) forms the hose (25) from a single material web (12) by means of a reshaping device (24) and wherein a first part (2) of the pouring device (1) is fastened to the side (3) of the material web (12) forming the interior of the bag (5) before forming the hose (25).

Description

BACKGROUND OF THE INVENTION[0001]The invention relates to an apparatus, according to the preamble of claim 1, for forming, filling and sealing packaging containers each comprising a pouring device. The invention further relates to a method according to the preamble of the independent claim.[0002]An apparatus is already known from US 2003 / 0001002 A1. In the known apparatus, beverage cartons are produced with a pouring device comprising a straw. The pouring device, congruent with a hole formed in a material web, is arranged on the side of the material web that forms the subsequent inner face of the carton. From the outside of the carton, provision can be made to cover or seal the pouring device by means of a protective film.[0003]The known apparatus is not suitable for processing or introducing charges which require a certain shelf life or in which formation of germs has to be prevented or delayed, as is necessary, for example, in the case of milk or similar charges.SUMMARY OF THE INV...

AI Technical Summary

Benefits of technology

[0004]Proceeding from the stated prior art, the object of the invention is to develop an apparatus for forming, filling and sealing packaging containers each comprising a pouring device, in such a way that it is also possible to package and introduce charges for which the shelf life and formation of germs are critical. At the same time, the structure of the apparatus is intended to be as simple as possible and to have only short downtimes in the event of malfunctions. The invention is based on the concept of sterilizing the material web and keeping it free of germs by using a sterilizing device that is arranged outside application devices for the pouring device, wherein the access to the application devices is particularly easy through sluices or the like not required in the area of the sterilizing device. It is thereby possible to carry out adjustment work or to fit the application devices with parts of the pouring device, without this requiring intervention in the area of the sterilizing device. In particular, a very quick restart after such interventions is thereby permitted.

[0006]In order to permit simple transport of the material web, in particular also via the forming shoulder, as soon as the first part of the pouring device is connected to the material web, provision is also particularly preferably made that the first part of the pouring device comprises a plate-shaped element that completely covers the hole in the material web, and that the second part comprises a mouthpiece with a lid element, which is connected to the first part, in particular by ultrasonic friction welding. By means of the plate-shaped element being relatively thin in its height, it is easily possible to draw the material web over the forming shoulder and the device for forming the bags, without these needing to have a particularly complicated design to ensure that they do not conflict with the first parts of the pouring device.

[0007]Arranging the pouring device in the head area of the bags has the advantage that the bags can easily be completely emptied by tilting the bags.

[0008]Moreover, production facilities are particularly preferred which comprise at least two mutually parallel apparatuses according to the invention for forming, filling and sealing bags each comprising a pouring device. In this way, the output of the installation can be increased relatively easily, and it may also be possible to use, for example, the same devices, for example the same delivery devices, in order to reduce the cost of equipment for a defined output.

Problems solved by technology

The known apparatus is not suitable for processing or introducing charges which require a certain shelf life or in which formation of germs has to be prevented or delayed, as is necessary, for example, in the case of milk or similar charges.
