Method and system for filling containers with a liquid filling product, and filling machine and labelling device for use with this method or system

Abstract

The consumer, and in particular the beverage consumer, frequently demands different packaging units which consist of different beverages or different assortments of beverages. That means that packaging units must be assembled which contain, for example, two bottles of a carbonated fruit-flavor beverage and four bottles of a beverage containing cola. The labelling and other packaging of the container must correspond to the product In the individual container. The packaging units are generally assembled either manually or semi-automatically. The invention relates to a method which simplifies the preparation of packaging units which contain different filling products. The invention is characterized by the fact that to fill the containers according to a Specified or selected filling formation with different filling products, i.e. optionally with at least a first or a second filling product, the filling machine is controlled by a control device so that, as a function of the filling formation, the filling positions dispense different products into containers which are unique and appropriate to each product.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention generally relates to a method for filling liquid products, in particular beverages, into bottles, cans or similar containers.

This invention also relates to a system for filling the liquid filling product.

This invention also relates to a filling machine for use with the method or system for filling liquid filling product, and to a labelling device for use with the method or system for filling the liquid filling product.

2. Background Information

The consumer, and in particular the beverage consumer, frequently demands different packaging units (e.g. cartons of three, six or twelve containers) which contain different beverages, in different numbers, different filling formations or different assortments. In practice, that means that packaging units must be assembled which contain, for example, two bottles of a carbonated fruit-flavor beverage and four bottles of a beverage containing cola. The type of container and the closing are thereby identical for the different products. The labelling or additional packaging of the container, however, must correspond to the respective product contained, and differs from product to product.

To meet this requirement, the known systems include systems which make it possible to assemble the packaging units from inventory manually or semi-automatically. This known method not only requires an additional expenditure of manpower, since the bottled or canned product must first be placed in storage in the warehouse and then taken out of the warehouse again, but the known method also means that to obtain the desired packaging units which contain at least two different products, two batches must be bottled or canned at two different times.

OBJECT OF THE INVENTION

The object of the invention is to create a method, an apparatus, and a system which simplifies the preparation of packaging units which contain different filling products.

SUMMARY OF THE INVENTION

The invention teaches that this object can be accomplished by means of a method and a system. A method, wherein, to fill the containers with different filling products, i.e. optionally with at least a first or a second filling product according to a specified or selected filling formation, the filling machine is preferably controlled by means of a control device so that the filling positions fill the different filling products into the appropriate containers for each filling product according to the filling formation. A system, wherein, to fill the containers with different filling products, i.e. optionally with at least a first or a second filling product according to a specified or selected filling formation, the filling machine can be preferably controlled by means Of a control device so that the filling positions fill the different filling products into the appropriate containers for each filling product according to the filling formation.

The invention teaches a filling machine for use in this method or system, wherein to fill the containers according to a specified or selected filling formation optionally with at least a first or a second filling product, the filling machine can preferably be controlled by means of a control device so that according to the filling formation, different filling positions or groups of filling positions dispense different filling products into suitable containers for each filling product.

The invention also teaches a labelling device for use in this method or system, wherein to label containers which are filled in a specified or selected filling formation, each of which may be filled with a different filling product, and are preferably transported in this formation to the labelling device, the at least one labelling station can be activated by a control device to label the containers in a manner which corresponds to the filling formations, so that each container is labelled with the label which corresponds to its contents.

In accordance with the invention, the desired filling formation can be selected or specified on a central control device (process computer). The process control then first controls the filling machine according to these instructions, so that the filling machine fills the corresponding containers in the filling formation with different filling product or contents, namely, each product in its own appropriate container. The filling positions can therefore form groups, for example, the number of groups equaling the number of the different products, whereby the filling positions of each group dispense a product into the corresponding containers as the rotor revolves. The number of filling positions in each group is also preferably defined by the control device, as a function of the desired or selected filling formation.

In one preferred embodiment of the invention, each filling position and the filling element located in it, has a connection for each product which leads to a supply line or a reservoir for this product, and has a switch valve device so that, under the control of the central control device, and as a function of the desired or selected filling formation, the respective filling position and the filling element located in it can be connected to the connection which corresponds to the product required.

One essential advantage of the invention is that the containers required for the packaging units to be manufactured can be filled with the required products during one filling process, i.e. it is no longer necessary to store the products in the warehouse even temporarily, which saves not only time and money, but also frees up warehouse space.

When the word "invention" is used in this specification, the word "invention" includes "inventions", that is, the plural of "invention". By stating "invention", the Applicants do not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and maintains that this application may include more than one patentably and non-obviously distinct invention. The Applicants hereby assert that the disclosure of this application may include more than one invention, and, in the event that there is more than one invention, that these inventions may be patentable and non-obvious one with respect to the other.

DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 shows a rinser 1, to which the containers, namely bottles 2, are fed in the direction indicated by the arrow A by means of a conveyor line 3, and downstream of which, in the direction of travel, the rinsed bottles 2 are transported by means of a conveyor line 4 formed by a star wheel conveyor to a filling machine 5 or its inlet star wheel. Downstream of the filling machine 5, in the direction of travel of the bottles 2, there can preferably be a closer 6 which closes the bottles 2. The closer 6 can be connected directly to a labelling device 8 by means of a conveyor line 7 formed by a plurality of star wheel conveyors. In the illustrated embodiment, the labelling machine has three outputs, namely one output formed by a conveyor 9 for bottles 2 which are filled with a first product, and are then labelled corresponding to this product, a second output formed by a conveyor 10 for those bottles 2 which are filled with a second product and are then labelled corresponding to this product, and a third output formed by a conveyor 11 which removes any bottles 2 which have been incorrectly labelled.

As also shown in the accompanying figures, the rinser 1, the filling machine 5 and the closer 6 form a common block of machines which has a common bottling table.

In the figures, 12 is a central electronic control device which includes a process controller which, among other things, controls the operation of the above-referenced system which is described in greater detail below.

The following comments relate to the individual components of the system:

Rinser 1

The rinser has the conventional construction and operation with which a technician skilled in the art would be familiar.

Filling Machine 5

The filling machine 5 is preferably of the revolving design, with a rotor 5' which revolves around a vertical machine axis. On the periphery of the rotor 5' there are a number of filling positions 13, each of which consists, in the conventional manner which is not illustrated in any further detail, of bottle carriers or container carriers, as well as a filling element 14 (see FIG. 2) located above the respective container carrier. In contrast to known filling machines, each filling element 14 is preferably connected by means of two connections 15 and 16 to a toroidal vessel 17 which contains the first product (by means of the connection 15) and to a second toroidal vessel 18 which contains the second product (by means of the connection 16). Each filling element 14 also preferably has, at the connections, two individually-controllable fluid or control valves 19 and 20, so that in each bottle 2 which is delivered at the inlet of the filling machine 5 to a filling position 13, the first product or the second product can be filled by means of an appropriate control of the filling product or fluid valves.

The two toroidal vessels 17 and 18 are components of the revolving rotor 5'. Each toroidal vessel 17 and 18 can be connected by means of a rotary coupling and by means of an external connecting line 21 and 22, respectively, to an external reservoir or mixer 23 or 24, respectively, to supply the respective product (mixer 23 for the first product and mixer 24 for the second product). The valves 19 and 20 can be actuated individually by the control device 12 on the basis of a desired program (filling formation), and by an element on each filling position 13 or on each filling element 14 which measures the fill level.

FIG. 2a illustrates a schematic representation of one embodiment of the present invention which shows how control device 12 could be operatively connected to each of the individual valves 19 and 20 by means of individual control units 19a and 20a being operatively connected to valve controllers 19b and 20b, respectively, on each valve. Each of these control units 19a and 20a can in turn be connected to and controlled by the control device 12. This allows control device 12 to control each filling element 14 separately, and to actuate either valve 19 or 20, depending on the pre-determined filling formation.

Closer 6

The closer 6 is preferably of the conventional construction, and is used to close the bottles 2 after they have been filled in the filling machine 5, for example, in the conventional manner with a cork closure, or with another suitable closure, and in particular regardless of what filling product or product the respective bottle 2 contains.

Labelling device 8

The labelling device 8 can have, on a revolving rotor 25, two individual labelling stations or units 26 and 27 which can be activated individually, each of which has its own label magazine 26' and 27'. For example, the unit 26 with the magazine 26' contains the labels corresponding to the first product, and the unit 27 with the magazine 27' contains the labels corresponding to the second product. Of course, each labelling station can also consist of a plurality of units, thereby producing an individual packaging for each product comprising a plurality of labels.

In the illustrated embodiment, the labelling device 8 also has an outlet star wheel 28, on which there preferably are electrically adjustable or controllable guide elements which act as "switches", so that the closed and labelled bottles 2 can be fed in a controlled manner to a conveyor belt or output 9-11. The labelling machine 8 or its functional elements, i.e. in particular the labelling stations 26 and 27 and the outlet star wheel 28 and its guide elements which act as switches, can be controlled by the control device 12.

The conveyor segments 9 and 10 can preferably lead to a packer 29. To essentially prevent gaps in the transport of the filled and labelled bottles 2 to this packer 29, which gaps are caused by the rejection of incorrectly filled and/or closed and/or labelled bottles 2, the conveyor lines 9 and 10 can form buffer zones.

Operation

The operation of the system is described below.

In accordance with the wishes expressed by the customer, each packaging unit 30 should contain a defined number of bottles 2 with the first and the second product after packaging. This desired assortment or formation is preferably entered into an input of the control device 12, so that then, when the filling process begins, the control device 12 and its process controller can control the valves 19 and 20 as a function of the specified filling formation, namely, so that as the rotor 5' revolves, a first group of filling positions 13 fill the bottles 2 located in them with the first product, and a second group of filling positions 13 fill the bottles 2 located in them with the second product, in a specified sequence or order. The process is preferably controlled so that during the entire filling process, i.e. until the filling machine 5 is shut down and cleaned, each filling position 13 is used during each revolution of the rotor 5' to dispense the same product, i.e. either to dispense the first product or to dispense the second product; in other words, there is no switching or changing of the individual filling positions 13 from one product to the other.

In the sequence defined by the actuation of the valves 19 and 20 regarding filling with the different products, the bottles 2, after they have been closed, travel via the conveyor line 7 to the labelling device 8.

The sequence imposed at the filling machine 5 of the bottles 2 filled with the different products, which is also called the filling formation, is transmitted by the control device 12 to the labelling device 8 which controls or activates the labelling units 26 and 27, namely so that there is a synchronization of the respective labelling unit and thus also of the packaging of each bottle 2 so that the label applied corresponds to the product the bottle contains. For those bottles 2 which are filled with the first product, the unit 26 is always activated, so that the bottles 2 are then provided with the packaging appropriate to the first product, and for those bottles 2 which are filled with the second product, the unit 27 is activated, so that these bottles 2 are then provided with the packaging appropriate to the second product. By means of the outlet star wheel 28, the bottles 2 are then sorted as a function of the product they contain, and are transported to the conveyor belt 9 or 10, or if they have been incorrectly filled, closed or labelled, they are transported to the conveyor belt 11.

FIG. 1a illustrates schematically one possible embodiment of the present invention wherein both the filling machine 5 and labelling device 8 each include a rotary angle transducer 5a and 8a, respectively. These angle tranducers 5a, 8a can be operatively connected to the control device 12, thereby allowing the control device 12 to monitor and regulate the rotating of the filling machine 5 and the labelling device 8 relative to one another.

At the packer 29, the groups of bottles which correspond to the desired formation are then formed from bottles which contain the first and second product, and are placed in the corresponding boxes 30.

FIG. 3 is a schematic representation of one possible way that control unit 12 can be operatively connected to the individual stations the bottles 2 pass through as they are conveyed along one embodiment of the present invention.

The invention was explained above on the basis of one embodiment. It should be understood that modifications and variations can be made to the invention without thereby going beyond the scope of the invention. For example, in a variant of the embodiment described above, it is possible, on the labelling device 8, to have a plurality of label magazines on a common labelling unit, which magazines are then activated by the control device as a function of the filling formation carried out by the filling machine, so that the correct labels and packaging can be used for each product. It also goes without saying that it is also possible to use containers other than bottles 2, e.g. cans.
