Patent number: 7727567Abstract: To establish the integrity of a product located in a container a given feature of the product in the container is determined by means of a first measurement method in which a first physical property of the product is ascertained, the given feature is additionally ascertained at least directly or by means of a second measurement method which is based on a second physical property which is different from the first physical property, and the values obtained by means of the two measurement methods of the given feature are compared. If the product is a drink in a bottle and if the given feature is the fill level, the first measurement method can consist of the fill level being measured by means of absorption of an X-ray beam, and the second measurement method can consist of the change effected by the bottle in the resonant frequency of a high-frequency oscillating circuit being measured.Type: GrantFiled: November 7, 2005Date of Patent: June 1, 2010Assignee: Heuft Systemtechnik GmbHInventor: Bernhard Heuft

Patent number: 6732921Abstract: In the system for managing a large number of reusable multi-trip receptacles each of which is marked by a code in an identifiable manner, the multi-trip receptacles are used in a number of cycles in several local stations (20, 21, 22) separated from each other and the code is read at each cycle. Data which have been recorded in the local stations. (20, 21, 22) for the individual multi-trip receptacles are stored allocated to the read code in a central station (10), and are evaluated to establish the number of cycles or uses of each multi-trip receptacle. The age and number of uses of each multi-trip receptacle is established using the data stored in the central station (10) and when a certain age or a certain number of cycles is reached, the local stations (20, 21, 22) are informed that the relevant multi-trip receptacle is no longer to be used.Type: GrantFiled: July 25, 2001Date of Patent: May 11, 2004Assignee: Heuft Systemtechnik GmbHInventors: Bernhard Heuft, Friedrich Wehren

Patent number: 6588575Abstract: The device (20) for diverting individual items from a stream of items which are conveyed on a transport apparatus has an extendable and retractable diversion element (22), which is operated via a gear unit (26, 28, 30, 32, 34) by a drive apparatus moving or swinging to and fro and is precisely time-controllable, in order to impart a cross impulse to items to be diverted so that they slide from the transport apparatus (11) across the direction of transport. The diversion element (22) carries out a complete extension and retraction movement during a single to-or-fro movement or swing of the drive apparatus. The drive apparatus moving to and fro can be a pneumatic cylinder (42), and the gear unit which transmits the piston movement to the diversion element (22) can be a coulisse link mechanism (26, 28, 30, 32, 34) or a toggle lever.Type: GrantFiled: November 1, 2001Date of Patent: July 8, 2003Assignee: Heuft Systemtechnik GmbHInventors: Bernhard Heuft, Gerd Kristandt

Patent number: 6494083Abstract: To test the tightness and/or the correct closure of containers which are transported on a conveyor, the containers succeeding each other at brief time intervals and the containers being sealed by attachment of a closure, a characteristic dependent on the internal pressure (internal-pressure characteristic) of the container is measured. Upon attachment of the closures to the containers, the internal-pressure characteristic or parameters of the closures or containers, knowledge which is necessary to measure the characteristic depending on the internal pressure, are recorded. The containers are marked no later than when the closure is attached in a way which permits the values recorded upon attachment of the closures to be allocated to the respective container.Type: GrantFiled: January 25, 2001Date of Patent: December 17, 2002Assignee: Heuft Systemtechnik GmbHInventor: Bernhard Heuft

Patent number: 6443004Abstract: To ascertain the fill level of vessels (10), mechanical vibrations are produced in a vessel wall (30) and the vibration pattern is analysed. The vibration is produced in a vessel wall (30) which is contacted by the contents to an extent which varies depending on the fill level, and the vibration pattern is then evaluated to discover to what extent the vessel wall (30) is contacted on the inside by the contents. For this, the decay time, the frequency, the intensity and/or the time integral of the intensity can be evaluated or the site of the maximum intensity of the mechanical vibrations in the vessel wall can be ascertained.Type: GrantFiled: October 18, 2000Date of Patent: September 3, 2002Assignee: Heuft Systemtechnik GmbHInventors: Bernhard Heuft, Hans-Ulrich Goller

Patent number: 6430991Abstract: To test closed containers, e.g. with regard to residual air volume or the quality and tightness of the closures which are attached to containers, mechanical oscillations are excited in the closure, the mechanical oscillations are analyzed, measurement values are derived from this, these measurement values are compared with pre-set values for acceptable closures and a signal is produced which states whether the measurement value corresponds to a value for an acceptable closure. To increase the reliability of the test, the oscillation properties of the closure blanks (R) are also ascertained before their attachment to the containers (B) and the range of acceptable values of the closures (V) attached to the containers (B) is chosen according to the oscillation properties of the corresponding closure blank (R). The closure blanks (R) can be classified according to their oscillation properties.Type: GrantFiled: January 25, 2001Date of Patent: August 13, 2002Assignee: Heuft Systemtechnik GmbHInventor: Bernhard Heuft
