Definitions

  • the present invention relates to a closing device for closing a container with a container closure, for example for closing a container with a push-on closure or a screw closure in a beverage filling plant, and to a method for monitoring a closing device for closing a container with a container closure, for example for closing a container with a push-on closure or a screw closure in a beverage filling plant.
  • Closing devices for closing containers with a container closure are well known in the art. For example, a container closure fed via a pick wheel is gripped by the pick wheel's clamping jaws of a gripping mechanism and then held on the closing device by the gripping mechanism. The closing head of the closing device, which holds the container closure, is then positioned over the container to be closed and lowered onto it to close the container with the container closure. If a screw closure is to be applied to the container, the closing head undergoes a rotating movement in addition to the lowering movement. The combination of lowering and rotating allows the screw closure to be screwed onto the container.
  • the state of the art provides systems that allow the replacement of closure-related components of the closing device, such as parts of the gripping mechanism, to enable the application of container closures of different geometries using the same closing head. Replacing these components is complex.
  • the EP 0 876 991 B1 shows a device for screwing a cap onto a container neck, which has gripping means pivotable about horizontal axes and provided with clamping jaws for clamping the cap.
  • gripping means pivotable about horizontal axes and provided with clamping jaws for clamping the cap.
  • a similar construction is shown by a screwing and rolling head for attaching threaded caps, which is shown in EP 1 908 725 B1 is known.
  • the US 5 851 042 A shows a clamping bushing for gripping container lids, which can be quickly exchanged using a locking pin on a closure gripping system.
  • the segments of the clamping bushing are bent inward by a pressure cylinder to enable gripping of the container lid.
  • the gripping mechanism of a closure device can be actuated by an actuating unit.
  • the gripping mechanism can be preloaded into a certain position and moved into another position, such as an open position, by the actuating unit.
  • a closing device for closing a container with a container closure for example for closing a container with a push-on closure or a screw closure, in a beverage filling system with the features of claim 1.
  • a closing device for closing a container with a container closure for example for closing a container with a push-on closure or a screw closure in a beverage filling plant, comprising a gripping mechanism for gripping the container closure with at least one gripping arm pivotable about a bearing and an actuating unit for actuating the gripping mechanism.
  • the closing device further comprises a detection unit for detecting a stroke of a lifting element of the actuating unit acting on the gripping mechanism.
  • various parameters can be determined, which in turn allow conclusions to be drawn, for example, about the actual switching times of the gripping mechanism. This can, in turn, be used to achieve higher system performance of a container closing device that includes the closing device.
  • the measured stroke can also be used to obtain information regarding the condition monitoring of the closing device, particularly with regard to the parts of the gripping mechanism.
  • parameters of the closing device such as the closing time and the opening time, can be automatically determined depending on the type of container closure currently being processed.
  • Detecting the stroke also allows conclusions to be drawn about the current wear of the closing device, especially when the currently measured stroke, especially the stroke at the time of closing and/or opening of the gripping mechanism, is compared with values recorded initially, for example, during or shortly after setup. Accordingly, wear limits can be determined to plan or initiate the replacement of wear-prone parts of the closing device.
  • the detection of the stroke can be used to detect system errors in the programming, mechanics and/or pneumatics of the closing device and/or the container closing device comprising it.
  • the recorded stroke values can also be used to determine further data for the digitalization of the closing process.
  • the closing device can optionally comprise an evaluation unit for determining at least one of the above parameters.
  • the container closing device can also comprise such an evaluation unit.
  • a central system control system for a container treatment system can be provided.
  • the detection unit can comprise at least one sensor, for example, a non-contact sensor.
  • a non-contact sensor can be, for example, a displacement sensor, for example, in the form of a Hall sensor.
  • the actuating unit can be designed as an actuating cylinder.
  • the lifting element can be a cylinder piston of the actuating cylinder.
  • a reference element can be arranged on the lifting element, optionally extending perpendicular to the stroke direction of the lifting element.
  • the reference element can serve as a reference for the sensor used.
  • a displacement sensor or distance sensor can measure the distance between itself and the reference element, with the stroke being based on or corresponding to the measured distance or a change in the distance.
  • the closing device may further comprise a control unit which is configured to determine at least one state variable of the gripping mechanism based on at least one signal of the detection unit.
  • the state variable can be indicative of wear of the gripping mechanism or correspond to wear of the gripping mechanism.
  • the control unit can be configured to use the determined state variable to draw conclusions about the condition and/or existing wear of the gripping mechanism and, in turn, to use this state variable as a data basis, for example, to output a warning and/or control signals in response to the processing of the determined state variable.
  • control unit can be configured to initiate an adjustment of at least one operating parameter of the closing device based on at least one signal of the detection unit and/or at least one determined state variable, wherein optionally at least one operating parameter is a control point and/or switching time for controlling the lifting element.

  • the lifting unit may comprise a fastening part for fastening to a transport unit of a container treatment device and a relative to the fastening part in a displacement direction displaceable moving part, wherein the moving part is connected to the gripping mechanism.
  • the moving part can comprise the actuating unit.
  • a particularly simple structure can be achieved if the displacement direction and the lifting direction of the lifting element are oriented parallel, whereby a central longitudinal axis of the moving part and a central axis of the lifting element can be concentric to each other.
  • a method for monitoring a closing device for closing a container with a container closure for example for closing a container with a push-on closure or a screw closure in a beverage filling plant, which comprises a gripping mechanism for gripping a container closure with at least one gripping arm pivotable about a bearing and an actuating unit for actuating the gripping mechanism, is proposed.
  • a stroke of a lifting element of the actuating unit acting on the gripping mechanism is detected.
  • the method allows the advantages and effects described with regard to the closing device to be achieved in an analogous manner. A repetitive description of these is omitted to avoid redundancies.
  • At least one state variable of the gripping mechanism can be determined based on the detected stroke.
  • the state variable can be indicative of wear of the gripping mechanism or correspond to wear of the gripping mechanism.
