Description
Technical Field
The present invention relates to a method and apparatus for identifying the structural integrity of a container to be closed, for example for identifying bottle breaks in a beverage filling facility.
Background
In the filling of filled products into containers provided for this purpose, for example in the filling of carbonated beverages into glass bottles, the pressurization of the containers, in particular of the glass bottles, often causes the individual containers to burst or fracture. This can be caused, for example, by pre-damage to the bottle. For this reason, it is known to use apparatus and methods for identifying compromised containers having reduced, defective structural integrity. Thus, bottle breakage can be identified, especially when filling glass bottles.
In order to detect bottle breaks, it is known in particular to continuously check the sound generated in the filling machine, wherein a bottle burst can generate characteristic acoustic pulses, as is known, for example, from DE 2634637 A1. Such devices are obligatory with a complex design, which is necessary in order to be able to detect and evaluate the acoustic pulses with a sufficiently high resolution.
Another type of damage identification in the container is monitoring the filling pressure when filling the container with the filling product, as is known for example from WO 19048051 A1 or EP 2832681 B1. These methods hide the risk of failing to identify each fracture. Depending on the filling process, the gas valve is usually left open after the actual filling process until the cavity is depressurized after closing. Thus, according to the bottle rupture diagram, this causes: the pressure in the station is not decisively affected by the rupture.
US 4511044A shows a device in which the force applied in the longitudinal direction during closure for closing a container is measured and compared with a preset standard. If the measured force lies outside a preset criterion in the longitudinal direction, it is inferred that the container is defective. For measuring forces in the longitudinal direction, a measuring variable sensor in the form of a piezoelectric crystal is arranged between the highly movable cover means and the fixed guide.
Disclosure of Invention
Based on the known prior art, it is an object of the present invention to provide an improved method for identifying the structural integrity of a container to be closed, preferably for identifying bottle breaks in a beverage filling plant, and to provide a corresponding device.
The object is achieved by a method for identifying the structural integrity of a container to be closed, preferably for identifying a bottle rupture in a beverage filling facility. Advantageous modifications emerge from the present description.
Accordingly, a method for identifying the structural integrity of a container to be closed, preferably for identifying a bottle rupture in a beverage filling facility, is proposed, comprising the steps of: accommodating a closure to be applied to a container to be closed in a closure accommodating apparatus of a closure mechanism; moving the capping mechanism in a longitudinal direction to an initial height position; and determining a force acting on the cap receiving means in the initial height position along the longitudinal direction. The method is characterized in that the force acting in the longitudinal direction is determined by detecting an open/closed loop control current of an electric drive providing movement of the capping mechanism in the longitudinal direction.
The force acting in the longitudinal direction is determined by detecting an open/closed loop control current of an electric drive providing movement of the closure mechanism in the longitudinal direction, whereby additional components and method steps for identifying containers with reduced and/or defective structural integrity, in particular bottle breaks, can be dispensed with. Accordingly, the manufacturing costs, maintenance costs, and running costs of the apparatus performing the method may be reduced as compared to conventional apparatuses. Furthermore, it is thereby possible to recognize defective and/or reduced structural integrity, in particular bottle breakage, relatively early, whereby it is possible to start taking a flushing action to flush out containers detected as defective, for example, before a new container is advanced into the container receptacle, which simplifies flushing out of fragments.
It is furthermore possible, in contrast to the method using pressure measurements during the filling process, to identify errors in the structural integrity, in particular bottle breaks, that occur during the filling process, the compression process and the closure process of the container or that result from the above-mentioned processes.
The term "height position" corresponds to a position with respect to the longitudinal direction. In other words, the height position of the capping mechanism can be changed by movement of the capping mechanism in the longitudinal direction.
The capping mechanism is preferably configured for applying a crown cork closure to a container to be closed. However, the capping mechanism can alternatively be configured as desired and in accordance with the desired container closure, and can be configured in addition to a crown cork capping machine, in particular: a screw capping machine for applying screw caps provided as molded articles; a winding or rolling capping machine for winding or rolling a container closure onto the external threads of a filled container; a capping mechanism for applying a bottle stopper, cork or otherwise closing the filled container in any other manner.
If the open-loop/closed-loop control current of the electric drive is detected continuously and/or periodically in relation to the position control of the closure mechanism according to a further development, containers with defective structural integrity, in particular ruptured bottles, can be identified without additional effort for detecting further measured values.
To determine the force in the longitudinal direction, according to one embodiment, the detected open/closed loop control current can be compared with values in a reference table.
Alternatively and/or additionally, the force in the longitudinal direction can be determined from the result of a preset function which is related to the measured open-loop/closed-loop control current. Preferably, in this case, the measured open/closed loop control current is multiplied by a preset constant.
It can furthermore be provided that the force in the longitudinal direction is determined by an algorithm or artificial intelligence taking into account the open-loop/closed-loop control current.
It has proven to be advantageous to compare the measured forces in the longitudinal direction with a limit value, wherein a defective structural integrity of the container is identified by the limit value not being exceeded. In the event of a reduced structural integrity, in particular in the event of a bottle rupture, the closure receiving means are subjected to only reduced reaction forces or even substantially no reaction forces as a result of the container mouth. In a container having a reduced and/or defective structural integrity compared to a container having a defined structural integrity, the force to be applied by the electric drive in the longitudinal direction is thus reduced, which force is necessary for reaching the initial height position, so that a bottle breakage can be deduced if a certain value is not exceeded, which value has been determined beforehand by means of a test, for example.
According to a preferred development, the movement of the capping mechanism takes place in a position-controlled manner, wherein the position control is preferably an external control circuit, and further an internal control circuit belonging to the external control circuit is provided, wherein the internal control circuit then preferably has an open-loop/closed-loop control circuit of the electric drive.
Preferably, the closure receiving means is pressed against the closure mechanism by contact with the container to be closed against the spring force of a spring arranged between the closure mechanism and the closure receiving means when the closure mechanism is held in the initial height position. It is thereby achieved that during the process of closing the container by means of the closure accommodated in the closure accommodation device, the force acting on the container in the longitudinal direction by the closure mechanism is provided essentially by the spring or by its spring force. Thus, for example, the tolerances of the shape and position of the device and/or of the method parameters can be grasped relatively coarsely without the risk of overstocking the container during the closing process.
According to a preferred embodiment, the output signal is generated in response to the container being identified as not meeting the specified structural integrity, wherein the removal of the container, in particular the flushing of the container or container residues, is preferably triggered in response to the output signal.
The above object is also achieved by a device for identifying the structural integrity of a container to be closed, preferably for identifying a bottle rupture in a beverage filling plant. Advantageous refinements of the device emerge from the present disclosure.
Accordingly, a device for identifying the structural integrity of a container to be closed, preferably for identifying a bottle rupture in a beverage filling plant, is proposed, comprising: a capping mechanism having a cap receiving means for receiving a cap to be applied to a container to be closed; an electric drive that moves the capping mechanism in a longitudinal direction; and a measuring device for measuring a force acting on the closure receiving means in the longitudinal direction at least in the initial height position. The device is further characterized in that the measuring device is set up and constructed for measuring the force acting in the longitudinal direction by detecting an open/closed loop control current of an electric drive providing a movement of the capping mechanism in the longitudinal direction.
The measuring device is designed and constructed for measuring forces acting in the longitudinal direction by detecting an open/closed loop control current of an electric drive providing a movement of the capping mechanism in the longitudinal direction, whereby the advantages and effects described previously in relation to the method can be achieved in a similar manner.
Preferably, the electric drive is in the form of a stepper motor or a servomotor, preferably in the form of a linear motor or an electric cylinder.
The capping mechanism is preferably configured for applying a crown cork closure to a container to be closed. However, the capping mechanism can alternatively be configured as desired and in accordance with the desired container closure, and can be configured in addition to a crown cork capping machine, in particular: a screw capping machine for applying screw caps provided as molded articles; a winding or rolling capping machine for winding or rolling a container closure onto the external thread or onto the external thread in the region of the slot of the filled container; a capping mechanism for applying a bottle stopper, cork or otherwise closing the filled container in any other manner.
According to a preferred embodiment, the measuring device is designed and constructed for comparing the measured force in the longitudinal direction with a limit value and, in addition, for detecting defective structural integrity of the container if the limit value is not exceeded.
According to a further preferred embodiment, the cap holder is arranged movably in relation to the cap mechanism in the longitudinal direction, wherein a spring is arranged between the cap mechanism and the cap holder for exerting a spring force on the cap holder in the longitudinal direction.
Preferably, the spring length of the spring is greater than the installation length of the spring between the capping mechanism and the capping holder by a predetermined amount when the capping mechanism is in the initial height position and the capping holder is pressed against the capping mechanism by contact with the container to be closed against the spring force of the spring.
According to a further preferred embodiment, the measuring device is set up and constructed for comparing the detected open/closed loop control current with the values of a reference table to determine the force in the longitudinal direction.
Alternatively or additionally, the measuring device can be set up and configured to determine the force in the longitudinal direction from the result of a preset function associated with the measured open-loop/closed-loop control current.
Furthermore, the measuring device can be set up and constructed for measuring the force in the longitudinal direction by means of algorithms or artificial intelligence taking into account the open-loop/closed-loop control current.
According to a further preferred embodiment, an open-loop/closed-loop control device for the movement of the capping mechanism is provided, which is designed such that the movement of the capping mechanism takes place in a position-controlled manner.
According to a preferred development, the position control can be an external control circuit and an internal control circuit belonging to the external control circuit can also be provided, wherein the internal control circuit preferably has an open/closed-loop control circuit of the electric drive. In other words, a cascade control device can be provided.
According to a further preferred embodiment, the device further comprises a filling means for introducing the filling product into the container to be filled, wherein a treatment chamber is preferably provided for sealingly receiving the container to be filled, wherein the capping means and the filling means are each movable in a sealing manner relative to the treatment chamber.
In other words, a device for combined filling and closing of containers is proposed, wherein a filling and closing mechanism is provided on the device, which can be applied to or removed from the container in succession, in order to first fill the container and preferably close it immediately without the container moving relative to the device, wherein the device for detecting the structural integrity of the container to be closed, preferably for detecting a bottle break in a beverage filling system, is constructed according to one of the embodiments described above. In particular, if a treatment chamber is additionally provided, only one treatment chamber has to be subjected to a negative pressure and/or an overpressure for filling and subsequent sealing, which can also be present or maintained during sealing during filling.

Detailed Description
Hereinafter, preferred embodiments are described with reference to the accompanying drawings. Here, in different drawings, the same, similar, or functionally identical elements are provided with the same reference numerals, and repeated descriptions of these elements are partially omitted to avoid redundancy.
Fig. 1 schematically shows a side view of a device 1 for identifying the structural integrity of a container 8 to be closed, wherein the container 8 is currently in the form of a bottle, and accordingly the device 1 is currently configured for identifying a bottle rupture in a beverage filling facility. The apparatus 1 comprises: a capping mechanism 2 having a cap receiving means 20 for receiving a cap (not shown) to be applied to a container 8 to be closed; an electric drive 3 for moving the capping mechanism 2 in a longitudinal direction 4; and a measuring device 50 for measuring the force acting on the closure receiving device 20 in the longitudinal direction 4 at least in the initial height position H0.
Currently, the measuring device 50 is formed as an integral part of the open-loop/closed-loop control means 5 of the device 1. Alternatively, the measuring device 50 can also be provided separately from the open-loop/closed-loop control means 5.
The measuring device 50 is set up and constructed to measure the forces acting in the longitudinal direction by detecting an open/closed loop control current of the electric drive 3 providing the movement of the capping mechanism 2 in the longitudinal direction 4. For this purpose, the measuring device 50 is set up and constructed for determining the force in the longitudinal direction from the result of a preset function relating to the measured open-loop/closed-loop control current, which is multiplied by a preset constant, in order to thereby obtain the force in the longitudinal direction.
Alternatively, in order to determine the force in the longitudinal direction, the detected open/closed loop control current can be compared with values in a reference table, or the force in the longitudinal direction can be determined by an algorithm or artificial intelligence taking into account the open/closed loop control current. Furthermore, alternatively, force measurements of the above-described type can also be combined.
The measuring device 50 is furthermore designed and constructed for comparing the measured force in the longitudinal direction 4 with a limit value and for identifying defective structural integrity of the container if the limit value is not exceeded.
The open-loop/closed-loop control device 5 for moving the capping mechanism 2 in the longitudinal direction 4 is designed such that the movement of the capping mechanism 2 in the longitudinal direction 4 takes place in a position-controlled manner, wherein the position control is currently optionally an external control circuit and an internal control circuit belonging to the external control circuit is furthermore provided, wherein the internal control circuit optionally has a control circuit of the open-loop/closed-loop control current of the electric drive.
The device 1 furthermore has: an optional filling mechanism 6 for introducing the filled product into the container 8 to be filled prior to closing; and an optional treatment chamber 7 for sealingly receiving an inlet region of a container 8 to be filled, wherein the capping mechanism 2 and the filling mechanism 6 are each sealingly movable relative to the optional treatment chamber 7.
In the present embodiment, the capping mechanism 2 is configured for applying a crown cork closure to a container 8 to be closed. However, the capping mechanism 2 can be configured as desired and according to the desired capping, and can be configured, in addition to a crown cork capping machine, in particular: a screw capping machine for applying screw caps provided as molded articles; a winding or rolling capping machine for winding or rolling a container closure onto the external thread or onto the external thread in the region of the slot of the filled container; a capping mechanism for applying a bottle stopper, cork or in any other way closing the filled container 8.
The cap holder 20 is currently arranged movably in the longitudinal direction 4 relative to the cap mechanism 2, wherein a spring 22 for applying a spring force to the cap holder 20 in the longitudinal direction 4 is arranged between the cap mechanism 2 and the cap holder 20. For this purpose, the spring 22 is supported on one side on the capping mechanism 2 and on its opposite side on the cap holder 20.
A detailed view of the device 1 in fig. 1 is schematically derived from fig. 2. As shown in fig. 2, the installation length 24 of the spring 22 between the capping mechanism 2 and the capping holder 20 is smaller than the spring length of the spring 22 in the unloaded state, wherein the capping mechanism 2 is in the initial height position H0 and the capping holder 20 is pressed against the capping mechanism 2 by contact with the container 8 to be closed against the spring force of the spring 22. The spring 22 thus presses the closure receiving device 20 against the container 8 with a force FF, which is formed as a function of the difference between the installation length 24 and the spring length in the unloaded state as shown in fig. 2 and the spring constant of the spring 22. Since the spring 22 is supported on the capping mechanism 2 in the longitudinal direction 4 relative to the capping holder 2, the electric drive 3 has to exert a corresponding force FL in the longitudinal direction 4 in order to keep the capping mechanism 2 at the level of the initial height position H0.
In fig. 3, the device 1 of fig. 2 is schematically shown together with a damaged container 8', wherein the damaged site is indicated in the form of a rupture by reference numeral 80. As a result of the container 8' having the defect in the form of the rupture 80, the container 8' has a reduced structural integrity such that, compared to fig. 2, only a reduced reaction force is provided when the initial height position H0 of the capping mechanism 2 of the container 8' is the same. Accordingly, the spring force FF' exerted by the spring 22 is less than the spring force FF in fig. 2. Accordingly, the electric drive 3 also only has to provide a reduced force FL' in the longitudinal direction 4 in order to hold the capping mechanism 2 in the initial height position H0.
Complete rupture of the bottle or container 8' may result in substantially no reaction force against the closure mechanism 2 or closure receiving means 20 due to the container finish.
Fig. 4 schematically shows a flow chart of a method for identifying the structural integrity of a container 8 to be closed, which method can be performed, for example, on the device 1 in fig. 1-3.
A method for identifying the structural integrity of a container 8 to be closed is currently constituted for identifying bottle breaks in beverage filling facilities, said method essentially comprising the steps of:
the closure to be applied to the container 8 to be closed is accommodated in the closure accommodation device 20 of the closure mechanism 2 (S10), the closure mechanism 2 is moved in the longitudinal direction 4 to an initial height position H0 (S11), and the force acting on the closure accommodation device 20 in the initial height position H0 along the longitudinal direction 4 is determined, wherein the force acting along the longitudinal direction 4 is determined by detecting an open/closed loop control current of the electric drive 3 providing a movement of the closure mechanism 2 in the longitudinal direction 4 as described above.
In order to be able to conclude that the container 8 is defective or has a defined structural integrity, the measured force FL is compared with a limit value F, G (S13). If the measured force FL in the longitudinal direction 4 is greater than the limit value F, G, the structural integrity of the container 8 is considered to be satisfactory (S13). If the measured force FL does not exceed the limit value F, G, this is regarded by the measuring device 50 as insufficient structural integrity, which corresponds to a damaged container 8'.
Fig. 5 schematically shows a flow chart of a further method for detecting the structural integrity of a container 8 to be closed. The method substantially corresponds to the method shown in fig. 4. Accordingly, the method has method steps S10 to S14. Additionally, after method step S14, the method comprises outputting an output signal (S15), after which the open/closed-loop control device 5 lifts the capping mechanism 2 from the container 8 '(S16), and after the capping mechanism 2 reaches another preset height position (S17), the flushing of the defective container 8' is triggered (S18).
Fig. 6 shows a schematic diagram from which the height position H of the closure mechanism 2 of the device 1 in fig. 1 over time t and the measured force FL of the device 1 in fig. 1 over time t in the longitudinal direction 4 are shown up and down.
In this case, two closing processes V1, V2 are shown, the first closing process V1 being the closing process in the case of a defined container 8, and the second closing process V2 being the closing process in the case of a defective container 8'.
The profile of the holding force FL of the electric drive 3 over time t during the capping mechanism 2 is in the initial height position H0 is denoted by the reference sign FL, H0 (t). In the closing process of the defined container 8, which corresponds to the first closing process V1, forces of up to about 3000N occur. In the case of a complete bottle rupture corresponding to the second closing process V2, during the closing process of the defective container 8', substantially no reaction force is generated, so that the holding force FL to be applied by the electric drive 3 is negligibly small. If the measured force FL does not exceed a preset limit value at any point in time, currently, alternatively, 600N,800N,1000N,1500N or 2000N, for example, a bottle rupture can be inferred therefrom.
Alternatively, an average value of the measured forces FL, H0 (t) can be formed during the initial height position H0 of the capping mechanism 2, and this value can be used as a comparison value with respect to a preset limit value. Furthermore, an integral of the measured forces FL, H0 (t) can also be formed in order to use this as a comparison value with a corresponding predetermined limit value.
As far as applicable, all individual features shown in the embodiments can be combined and/or interchanged with one another without departing from the scope of the invention.
