Abstract

A foil strip (1) is fed from the outside to a vertical wrapping material tube (3) to shape it into a bag and seal it with a first seam down the long side. Material of greater mass/quantity is measured by using the inside of the wrapping material tube and inserted in a bag (2) sealed with double seam. During the filling process with material of greater mass, material of smaller mass is measured out in a weighing device (13)/vibrating channel. An Independent claim is also included for a device for cyclic filling of foil double-chain bags with substances of different consistency or mass.

Description

The invention relates to a method and an apparatus for cyclical filling of double foil chain bags with fabrics different consistency and / or mass, being a foil tied to a substantially vertically arranged envelope material pipe guided on the outside, shaped into a tubular bag and sealed on the long side and with a first transverse seam then the substance of greater mass and / or quantity dosed into the bag via the inside of the casing material brought and a double cross seam to the bag closure is realized according to the preamble of claim 1 or 7.

So-called tubular bag machines for filling or packaging of goods of all kinds belong to the state of the Technology. For example, please refer to the machines of the Hassia Redatron GmbH, Hüttenberg.

In such tubular bag machines, the film web, which forms the later bag, to one in the machine in the essentially vertically arranged cladding tube outside guided on the side and initially lengthways and by means of a Cross seam sealed. Then in the resulting bag introduced the product to be filled. This is followed by Form a further transverse seam to the bag closure, at for example by heat sealing or pulse welding.  

Double chain bags are used for filling confectionery products or multiple chain bags belonging to the prior art. The Bags usually take products of the same origin or same consistency, amount or mass and can be from Customers separated along a given perforation line, d. H. be isolated.

As long as the products to be bottled are essentially one have the same consistency, mass or quantity Filling also with packaging machines of high productivity no particular difficulties.

However, the packaging of products is problematic their consistency or different mass, for example a rather heavy ready-made dough on the one hand and very light chunky toasted bread cubes as an addition typical Thuringian potato dumplings.

The Filling procedure regarding the substances of different mass can can also be realized in a reverse sequence of steps.

The material of larger mass is in particular ready-made dough and the substance of smaller mass consists of toasted bread or Bread cubes.

To prevent unwanted baking or sticking and thus one avoid poor dosage with poor filling quality, the roasted bread cubes are frozen on the Given weighing device and filled in the same state.

The bags filled with the substance of larger mass become Execution of the double cross seam of two movable press or Equalization plates fixed, the press plates as well as the Welding device the bag after filling with the fabric Keep smaller mass to separate and seal.  

Sealing is done by pulse welding the bag foil materials.

For improved, easier filling of the bag or respective bag chamber, in particular the chamber which the Picking up material of smaller mass is targeted compressed air supply provided to a defined inflation of the respective To reach the chamber.

The device side is based on a known The double-walled envelope tube machine trained or it has an inside separate filling channel. The inner tube takes one double-walled version the fabric of larger mass, e.g. B. Ready dough on, with the channel or the intermediate tube at double-walled version guides the fabric of smaller mass or transported.

At the top open end of the channel or intermediate pipe arranged a slide, which is on the transport side with a Format funnel communicates. The format funnel has controllable swing flaps for the targeted delivery of a Funnel located amount of e.g. B. roasted bread cubes.

A special electronic weighing device is for the fabric smaller mass provided as an additional assembly, these Weighing device has a weighing pan.

The weighed and therefore metered substance of smaller mass reaches the format funnel from the weighing pan. These The existing swivel flap is used for timed delivery the substance of smaller mass on the slide, the channel or the intermediate tube into the second chamber of the double chain bag.

For the safe transport of the substance of smaller mass are on the Slide vibrator arranged.

A storage container is located above the weighing device controllable inlet flap provided. Output side of the  Weighing pan is also a controllable closure facility arranged.

The weighing pan and / or the format funnel and / or the Storage tanks are designed to hold a lumpy, deep frozen good. In particular, the Storage container be thermally insulated and / or over a Have cooling equipment.

As already explained for the description of the method, the Substance of larger mass a dough-pasty quantity of ready-made dumplings and the substance of smaller mass consists of toasted bread or Bread cubes or similar lumpy added products a ready meal or a side dish, e.g. B. Thuringian Potato dumplings.

The invention is illustrated below with the aid of an embodiment game and a schematic representation explained in more detail become.

In the method for the cyclical filling of double foil chain bags with substances of different consistency and / or mass according to the exemplary embodiment, a foil web 1 , which forms the later shaped bag 2, is guided to a substantially vertically arranged wrapping material tube 3 .

Using a suitable welding device (not shown), the film web is first sealed longitudinally and the welding device 4 is used to form a first transverse seam.

By means of a metering valve 5 , the release and supply of ready-made dough as a substance of greater mass takes place, this substance being brought into the bag 2 via the wrapping material inside. Movable press plates 6 fix the bag and it is with the help of the welding device 4, a cross seam double formed. 7 The dough 8 is then received in the first chamber of the bag 2 tightly closed.

During the filling process of the bag 2 with dough 8 , a defined amount of the substance of smaller mass, in the concrete example roasted bread cubes, is provided from a storage container 11 , which has an inlet flap 12 , with the aid of an electronic weighing device 9 .

The metered amount of bread cubes 10 then passes through a weighing pan 13 , which is provided on the output side with a closure device 14 , into a format funnel 15 .

The format hopper 15 has two swivel flaps 16 for time-controlled delivery of the amount of bread cubes located in the format hopper 15 .

When the swivel flaps 16 are opened , the bread cubes 10 reach a slide 17 .

The delivery end of the chute 17 communicates with an upwardly open end of a channel or intermediate tube 18 in Wirkver bond.

The channel or the intermediate pipe 18 is in turn located inside the casing material pipe 3 . For example, the casing material tube 3 can be double-walled, an inner tube serving as the filling tube 19 for transporting the dough and the intermediate tube being used for transporting the bread cubes 10 .

In a quasi free fall, the bread cubes 10 then reach the still open second bag chamber above the double seam 7 . As the bag is transported further, a film section reaches the welding device 4 so that the bag section can be sealed above the second chamber of the bag and separated from the continuous film material strand.

The weighing pan 13 and / or the format funnel 15 and / or the storage container 11 for the bread cubes are designed to hold a lumpy, deep-frozen good. In particular, the reservoir can be thermally insulated and / or provided with a cooling device. Due to the deep-freezing of the bread cubes in the storage container, there is a particularly safe metering and feeding possibility, with the result of an exact measurement and filling of the second, smaller chamber of the bag with roasted bread cubes. For easier filling, in particular the chamber of the bag for holding the lighter substances, a defined inflation can be carried out by means of a compressed air generating device, not shown, whereby swirling of the filling material must be avoided.

On the slide and / or the weighing pan a can not darge posed vibrator to be arranged to an unwanted Adhesion of the products to be transported with the consequence of a to avoid disrupted transport.

With the device described, foil double chains can bags cyclically with substances of different consistency and / or mass can be filled, the film strip for im essentially vertically arranged cladding tube outside guided on the side and formed into a tubular bag there. How the bag is described by longitudinal sealing and forming a first transverse seam and then the material of greater mass, especially dough, over the The inside of the casing material tube is metered into the bag. A Double cross seam hermetically seals the filled fabric and forms a first seam of a second bag or one second chamber of a double chain bag.

During the filling process with the substance of greater mass Substance of smaller mass in the weighing device described dosed and after executing the double cross seam over one Ver channel in the inside of the wrapping material tube in the bag introduced. This is followed by separation, sealing and Eject the filled two-chamber or double chains bag.

Because the roasted bread cubes are frozen on the Weighing device arrive and are filled in this way, is a unwanted sticking and associated incorrect dosing safely avoided.
