Definitions
- the invention relates to a device and a method for attaching valve bags to a filler neck of a packaging machine and in particular a rotating packaging machine, which is equipped with a plurality of filler neck.
- Modern packing machines can fill 3600 valve sacks / hour or more, so one bag or more must be plugged per second, which is then filled during rotation until it is dropped at the intended discharge point filled with the intended weight.
- CONFIRMATION COPY already 36 sacks on the ground, which would add up to 360 sacks during the working day from 10 hours. Such a number of bags could interfere with the function unless the bags are collected at regular intervals.
- Valve bags made of a paper material are suitable. Bags made of paper have a relatively high inherent rigidity, so that they have defined and substantially predictable properties in the automatic Aufsteck- and filling.
- valve bags are plugged or shot open by a AufSteckautomaten on the filler neck of the packing machine during the rotational movement.
- shot applies to the situation insofar as the sacks have to bridge for a short distance unguided the space between the AufSteckautomaten and the filler neck of the packing machine.
- valve sacks made of paper In addition to valve sacks made of paper, valve sacks made of plastic film or of woven fabric or of woven fabric made of plastic materials are often used, which are often used without external or internal coating. Such
- the inventive device for attaching valve bags to a filler neck of a packaging machine has
- At least one AufSteck issued and at least one bag feed device and at least one valve opening channel is attached to the bag feed device on a filler neck of a packing machine.
- At least one blowing device for generating at least one air flow is provided in the valve opening channel. With the blowing device, at least one directed towards the outlet opening air flow can be generated to automatically open the valve of the valve bag in the valve opening channel.
- the device according to the invention has many advantages, as it allows the automatic insertion of valve bags on a filler neck of a packaging machine. Even if the material of the valve bags as a whole is relatively flexible, a stiff paper layer on the outside or the inside of the valve bags is not required to ensure a successful attachment of the valve bags to the filler neck of a particular rotating packaging machine.
- the blowing device comprises at least one
- Air nozzle In a preferred embodiment are in the
- Valve opening channel arranged at least two air nozzles on opposite sides. In each case at least one air nozzle is arranged in each case on each side of the valve opening channel. But it is also possible that on one or Both sides of the firing channel are each provided 1, 2 or more air nozzles. Particularly preferably, the unidirectional air nozzles are arranged symmetrically on each side, so that preferably the same conditions prevail on both sides of the bag valve.

- At least one directed towards the outlet opening air flow is generated to open the bag valve with the blowing device from at least one air nozzle.
- the air flow is aligned in the direction of movement of the bag or in the direction of the filler neck.
- the airflow blows to open from the rear along the sides of the bag valve and not from the front towards the valve. By blowing air in the direction of the bag valve, air could also be blown into the interior of the bag, which should be avoided.
- At least one air flow is generated in the direction of the outlet opening on each side of the bag valve within the firing channel.
- the airflow creates a depression, which causes an opening of the valve. If the airflow is activated at a suitable time before plugging in, and if necessary during the
- the bag valve reliably and reproducibly opened, even if the bag or the area of the bag valve made of flexible materials.
- Blower directed toward the outlet opening air flow not only opens the bag valve within the firing channel, but also exits the valve port and leads to better guidance of the bag on the way of the valve bag to the filler neck. As a result, a better flight stability of the valve bag is achieved, which must indeed bridge the way from the outlet opening of the firing channel to the filler neck of the packing machine.
- the blowing device comprises at least two
- Air jets on at least one side are aligned in particular in the direction of the outlet opening. By two or more different air nozzles on one side they can be controlled differently, in different directions

In the swung-out state, the opening shells do not hinder the rotation of a filling nozzle underneath. Therefore, in such an embodiment, thennenSteckvoriques be placed closer to the packing machine, whereby the AufSteckquote can be further increased, especially for very unstable bag materials.
- the valve opening device is opened directly after each shot and it will be the pivotable opening shells folded upwards.
