1. Technical Field
The application relates to a beverage bottling plant for filling bottles with a liquid beverage filling material, and an easily cleaned lifting device in a beverage bottling plant.
2. Background Information
Beverage bottling plants for filling bottles with liquid beverage filling material have a filling machine for filling bottles with a liquid in a container filling process. Such filling machines usually comprise a plurality of filling positions, with each filling position having a filling element to fill a corresponding bottle with liquid beverage filling material. There is possibly also provided an apparatus to move empty bottles to a filling element, and each filling element being configured and disposed to receive a corresponding bottles to be filled from said apparatus to move empty bottles. Upon filling, an apparatus removes a filled bottle from a filling element. There may possibly also be provided an apparatus to hold a bottle to be filled in sealing attitude at a filling element, and each filling element having a portion to introduce at least one process pressure into the interior space of a corresponding bottle, as well as at least one pressure sensor for each filling element, each sensor being disposed and configured to sense a pressure related to the interior of a corresponding bottle that is connected with the corresponding filling element, and each sensor being configured to produce at least one indication representative of a sensed pressure related to the interior of a corresponding bottle. There may also be provided a controller that is configured to receive from a corresponding sensor at least one indication representative of a sensed pressure related to the interior of a bottle; and apparatus configured to control at least one process parameter related to filling a bottle in the filling machine. That controller may be further configured to control the control apparatus for the at least one process parameter of the filling machine.
Also known are filling plant systems that include a cleaning station to rinse or otherwise clean containers such as bottles and the like. Thus, a beverage bottling plant for filling bottles with a liquid beverage filling material can possibly comprise a cleaning station to clean bottles, a beverage filling machine with a plurality of beverage filling positions, each beverage filling position having a beverage filling device for filling bottles with liquid beverage filling material. The filling devices may have an apparatus being configured to introduce a predetermined volume of liquid beverage filling material into the interior of bottles to a substantially predetermined level of liquid beverage filling material, and the apparatus configured to introduce a predetermined flow of liquid beverage filling material comprising apparatus being configured to terminate the filling of beverage bottles upon liquid beverage filling material reaching said substantially predetermined level in bottles. There may also be provided a conveyer arrangement being configured and disposed to move bottles, for example, from an inspecting machine to the filling machine.
Upon filling, a closing station closes filled bottles.
There may further be provided a conveyer arrangement configured to transfer filled bottles from the filling machine to the closing station, a labeling station in the event that labeling of the filled bottles is intended, as well as a loading station that is configured to load filled bottles into containers, for example, in a six-pack arrangement. There may also be provided a conveyor arrangement configured to transfer filled bottles from the closing station to the loading station, and to and from the labeling station.
There is increasing demand in the beverage industry to fill containers with a beverage that does not need to be subjected to heating, due to reasons of taste or due to other reasons. In the case of cold-aseptic filling it is of particular importance to carry out the entire processing, from cleaning of the containers to the actual filling stage and to the closing of the containers, in a manner that is devoid of germs.
This aim requires, as a rule, special configuration of the entire equipment. In this it is of particular importance to design the equipment in such a way that the presence of recesses, edges, or undercuts is minimized, because these structures favor the collection of dirt and/or damaging microorganisms and, furthermore, also impair cleaning of the machines.
Additionally, it is of substantial advantage, to provide devices that permit cleaning of the equipment in a simple manner. Thus, practical application particularly desires so-called CIP-installations (cleaning in process), because such installations permit low-cost cleaning, with the entire installation being automatically rinsed with a disinfecting medium.
While previously CIP-installations and also the respective configuration of many machines or, respectively, machine components, have been the subject of many publications, the corresponding configuration of lifting devices at the filling machines has hitherto been neglected.
Container filling machines are preferably of a design of rotating machines that have a plurality of filling elements at their rotors. Support plates or support tables that can be raised and lowered are associated with the filling elements, whereby the support tables receive the containers that are to be filled via input star wheels. Further, a so-called lifting device is associated with each of these support tables; with these lifting devices having the purpose of raising the containers that are disposed on the support tables towards the filling elements and to press the containers against the filling elements. There have also become known solutions in which the support tables are replaced by radially projecting gripper elements that grasp the containers at the neck portion and hold the containers, these containers being in such cases as a rule plastic bottles.
In order to accomplish the above-described function, these lifting devices generally comprise a combination of a fixed piston and a moveably disposed cylinder structure that surrounds this piston. The structural components are disposed vertically, and with the piston being rigidly connected to the rotor of the container filling machine. The cylinder can be moved up and down in vertical movements. The cylinder chamber or cavity that is established between the fixed piston and the moveable cylinder, is, in most cases, impacted by compressed air, the compressed air being passed through a bore or passage within the piston, such that the cylinder is urged to move in vertical direction to an upper position. This movement is limited by a roller that is secured to the cylinder, which roller is configured to rotate about its longitudinal axis, and with the roller contacting a curved path of a stationary cam structure. By way of the rotating movement of the rotor of the container filling machine, the roller rolls upon the curved path of the cam structure, that is, it follows the course of the curved path of the cam structure and simultaneously carries out an upwardly directed movement and a downwardly directed movement, which movements, due to the configuration of the design of the machine, are also carried out by the support table and, accordingly, a container supported on a support table.
Lifting devices have been proposed, for example, in German Patent No. DE 39 19 565. In its designed structure it follows the above-described features, but with means for cleaning of the lifting device not being present, this prior art embodiment providing a considerable disadvantage. German Patent No. 39 19 565 and its corresponding European Patent Application Publication 0 402 643 published on Dec. 19, 1990 and naming Andreas Finger et al. as inventors, are hereby incorporated by reference as if set forth in their entirety herein.
Lifting devices that comprise means to clean the lifting devices have hitherto not become known.
A further drawback with lifting devices arises in practical operation thereby that the seals that are disposed between the piston rod and the inner wall of the cylinder are subjected to high wear. Particularly contributing to wear is the fact that the seal is moved at a high frequency over a lengthy path over a smooth, but dry, metal surface.

The application is explained in greater detail below with reference to the accompanying drawings.
Further development details, advantages and possibilities of application of this present application can be obtained from the following description of embodiments and the drawing. With this, all described and/or illustrated features per se or in any combination, comprise the substance of this present application, regardless of their combination in the claims or their dependency. At the same time, the content of the claims is made a component of the description.
Downstream of the filling machine 105, in the direction of travel of the bottles B, there can preferably be a closer or closer station 106 which closes the bottles B.
The closer or closer station 106 can, for example, be connected directly to a labeling device or labeling station 108, such as, for example, by means of a conveyer line or conveyer arrangement 107 that may be formed, for example, by a plurality of star wheels of a conveyer arrangement.
In the illustrated embodiment, the labeling device or labeling machine or labeling station 108 has, for example, three outputs, namely one output formed by a conveyer or conveyer arrangement 109 for bottles B that are filled with a first product. The first product may possibly be provided by a product mixer 123 that is connected to the filling machine 105, for example, through a conduit 121, and bottles B that are filled with a predetermined volume of liquid beverage filling material, that is, the first product, are then labeled by a labeling module 108a in the labeling stations 108 corresponding to this first product delivered from product mixer 123 to the beverage filling machine 105 and thence to the corresponding bottles B.
A second output that is formed by a conveyer or conveyer arrangement 110 is provided for those bottles B that are filled with a second product. The second product may emanate from a second product mixer 124 that is connected, for example, through a conduit 122 to the filling machine 105, and these bottles B filled with a predetermined volume of liquid beverage filling material comprising the second product are then correspondingly labeled by a labeling module 108b in the labeling station 108 corresponding to this second product.
A third output, for example, formed by a conveyer or conveyer arrangement 111, removes any bottles B which have been incorrectly labeled as may have been determined by an inspecting device or an inspecting station, or an inspecting module 108c that may possibly form a part of the labeling station 108.
In
The beverage filling machine 105 is preferably of the revolving design, with a rotor 105′, which revolves around a vertical machine axis. On the periphery of the rotor 105′ there are a number of filling positions 113, each of which comprises a lifting device 113a that is configured and disposed to present bottles B for filling, as well as a filling device or element or apparatus 114 located or configured to be located above the corresponding lifting device 113a and the corresponding bottle B presented by the lifting device 113a. The details of a lifting device 113a are discussed in the following. The filling device or apparatus 114 comprises an apparatus configured to introduce a predetermined volume of liquid beverage filling material into the interior of bottles B to a predetermined level of liquid beverage filling material. Furthermore, the filling device or apparatus comprises an apparatus configured to terminate the filling of bottles upon liquid beverage filling material reaching the predetermined level in bottles B. In other words, filling elements 114 are configured and disposed to provide a predetermined flow of liquid beverage filling material from the source thereof, such as, product mixers 123 and 124, into the bottles B.
The toroidal vessel 117 is a component, for example, of the revolving rotor 105′. The toroidal vessel 117 can be connected by means of a rotary coupling or a coupling that permits rotation, and by means of an external connecting line 121 to the external reservoir or product mixer 123 to supply the product, that is, product mix one, for example.
As well as the more typical filling machines having one toroidal vessel, it is possible that in at least one possible embodiment a filling machine could possibly be utilized wherein each filling device 114 is preferably connected by means of two connections to a toroidal vessel 117 which contains a first product, say by means of a first connection, for example, 121, and to a second toroidal vessel which contains a second product, say by means of the second connection, for example, 122. In this case, each filling device 114 can also preferably have, at the connections, two individually-controllable fluid or control valves, so that in each bottle B which is delivered at the inlet of the filling machine 105 to a filling position 113, the first product or the second product can be filled by means of an appropriate control of the filling product or fluid valves.
It will be understood that while a two-product assembly or system of a bottling plant is illustrated in
As illustrated in
During the normal filling operation, the liquid that is employed as friction-reducing medium and/or cooling medium, is passed through the at least one second bore or passage 5.
By way of the single or several bores or passages 6 that are radially provided within the piston rod 1, that are in communication with the second bore passage 5, the disinfecting medium is passed to the inner wall of the cylinder 2.
By way of an appropriate selection of the parameters of volume stream and pressure during egress of the disinfecting medium from the radial bores or passages 6, it is ensured that the disinfecting medium also positively wets the piston rod 1 of the lifting element.
While the egress of the disinfecting medium during the cleaning phase is essentially continuously and concentrated, the egress of the cooling liquid and/or lubricating liquid during the regular course of filling can be continuously, or also be cyclically.
A connection and seal element 8 is disposed at the lower end of the piston rod 1 which element 8 provides a connection between the supply conduit for the compressed air and the disinfecting medium and the bores or passages 4 and 5.
By way of a change-over device, not shown in greater detail but known in the art, the at least one bore or passage 5 can be connected with the supply line of a cooling and/or lubricating liquid for the regular filling process, and for the commencement of a disinfecting process, with the supply conduit of the disinfecting medium.
With reference to
Bottle support table or support 21 forms part of the lifting device 113a and is secured to the upper end of the cylinder 2 so as to permit raising and lowering of the bottle support 21 and a bottle B supported thereon, when pressure is exerted upon the end-plug 19 that connects the bottle support 21 to the upper end of cylinder 2.
Thus, the upper stop structure 17 is secured to rotor 105′ of the filling machine adjacent the upper end of the rod 1 and the cylinder outer wall being configured to slide within the upper stop structure 17, say by intervention of seals 23 and 24a and 24b. There also possibly being provided a lowermost seal 25. The lower stop structure 15 is operatively connected to the upper stop structure 17 and is configured and disposed to slide on the outer wall of cylinder 2.
Spring 16 is disposed between the upper stop structure 17 and the lower stop structure or stop sleeve 15 and is configured to be compressed between the upper stop structure 17 and the stop sleeve 15.
Upon a pressure medium passing with a first, low, pressure through the longitudinal bore or passage 4 of rod 1 into the cylinder chamber 3, the cylinder 2 is raised providing a chamber portion 3a and thus, in turn, raises the bottle support 21 and a bottle B supported thereon to a first position, this being a position in which a bottle B is disposed away from a seal arrangement of a filling device 114, which first position is configured to permit filling of a bottle B with a still beverage, for example, milk. It will be appreciated that the force of the spring 16 and the low pressure preclude further raising of the cylinder 2 since the collar 12 will be in abutment with the stop sleeve 15 and maintains the cylinder 2 and thus the bottle support 21 and a bottle B supported thereon in the first position.
Upon a pressure medium passing with a second, high, pressure through the longitudinal bore or passage 4 of rod 1 into the cylinder chamber 3, the cylinder 2 is raised and thus, in turn, raises the bottle support 21 and a bottle B supported thereon to a second position, this being a position in which a bottle B is sealed to the sealing arrangement of filling device 114, which second position is configured to permit filling of a bottle B with an effervescent beverage, for example, beer.
So as to attain the second position, the spring 16 is compressed by the receiving-and-guiding element 13 and the stop sleeve 15 whereby the stop sleeve 15 has risen further upwardly, due to the force that is generated by the collar 12 bearing on stop sleeve 15.
The lower end of rod 1 has a fitting 8 that is sealed by way of a seal 8a in the lower end of rod 1. Fitting 8 accommodates the passage 4 for a pressure medium and the passage 5 for selectively introducing a cleaning medium, or a lubricating medium, or a cooling medium.
The valving arrangement to supply the lifting device 113a with a pressure medium comprises a supply of pressure medium 40 that is connected by line or conduit 40a to a valve arrangement 41. Valve arrangement 41 may possibly be part of a ring line or annular conduit 4a that is configured to connect a plurality of lifting devices 113a to one another. It will be appreciated that associated pumps, sensors and other components are included in the valving arrangement configured to supply the pressure medium through the longitudinal passage 4 in the lifting device 113a.
The valving arrangement that selectively supplies the lifting device 113a through the passage 5 with a cleaning medium, or a cooling medium, or a lubricating medium comprises a valve arrangement 50 to selectively supply a cleaning medium from cleaning medium supply 52 through a line 52a to the valve arrangement 50. Similarly, for normal filling operations, a lubricating medium from lubricant supply 54 is provided by way of line or conduit 54a to the valve arrangement 50. If cooling of the lifting device 113a is desired, the cooling medium is supplied from the coolant supply or cooling medium supply 56 through line or conduit 56a to valve arrangement 50 and thence to passage 5. Passage 5 may possibly be connected to a ring line or annular conduit 5a that connects the individual lifting devices 113a to one another so as to selectively receive the cleaning medium, or the lubricating medium, or the cooling medium.
The operation of the described valving arrangements may possibly comprise a control arrangement 60 to control introduction and release of the pressure medium, control arrangement 60 being schematically connected to the valve arrangement 41 by a line 60c and to the pressure medium supply 40 by a line 61, so as to illustrate this control of the introduction and release of the pressure medium. It will be appreciated that sensors and their signals supply the control arrangement 60 which process data, and the control arrangement 60 is configured to issue signals for automatic and controlled operation of the fluid supply for the lifting devices 113a. It may also be possible that the control arrangement 60 may possibly be controlled by the central controller 112.
Similarly, the control arrangement 60 is respectively connected by way of line 60a to the cleaning medium supply 52, the lubricant supply 54, and the coolant supply 56, and by way of line 60b to the valve arrangement 50. Control 60 may possibly also be connected to a distributor 64 that may possibly be part of ring line 5a.
Provision is made in a residue recovery 62 for the removal, as required, of excess portions of the cleaning medium or the lubricating medium that my possibly be removed through a bleed port 28 in cylinder 2 and a bleed line 29.
It will be appreciated that supply of the lubricating medium and of the cooling medium to the lifting device is possibly part of the normal filling operation of the filling machine 105. The provision of a cleaning medium to the lifting device 113a of the filling machine 105 may possibly be part of a planned cleaning of the filling machine 105.
Such cycles of filling and cleaning of filling machine 105 and the lifting devices 113a will depend on a number of factors, such as, type of container that is to be filled, which may comprise bottles, cans, cartons and the like. Other factors include condition of the material that is being filled into containers, for example, hot filling or cold filling, filling of a still beverage, such as, milk, or filling of an effervescent beverage, for example, beer.
