  • Patent number: 9664590
    Abstract: A container has a tube-like or tubular shell, which is sealed against the surrounding atmosphere and has a weld seam at at least one end. For checking the tightness of the container the internal pressure in an interior space of the container is increased by means of external action and the thereby ensuing deformation of the weld seam is detected. Provisions are made in this connection for the weld seam to be clamped between clamping elements before increasing the internal pressure only in a partial area of its surface, which has a distance from the end of the weld seam facing the interior space.

  • Patent number: 9216863
    Abstract: For the purpose of transferring a tube in a tube filling machine between a staging location and a set-down location, the tube at the staging location is gripped at its lateral surface by a holding device and transported by a transfer device to the set-down location where it is set down while simultaneously being rotated about its longitudinal axis or about an axis parallel thereto during transport. Such a transfer device has a multiple-member articulated arm, which has at least one 1st arm member that is mounted to pivot about a rotary axis and directly or indirectly pivotably supports at least one holding member. The holding member carries at least one holding device by means of which the tube can be picked up and which can be pivoted about an axis that is parallel to the longitudinal axis of the tube or that coincides therewith.

  • Patent number: 8919533
    Abstract: A transfer device for transferring a flat folding box to a succeeding conveyor device with simultaneous erection has a rotarily driven support part which is pivotable about an axis of rotation, and at least one further rotarily driven support part which rotates coaxially to the support part about the axis of rotation. The folding boxes are received in a receiving station by the retaining device and are conveyed on a curved track to a transfer station and therefore transferred to a succeeding conveyor device. Here the support parts perform a rotary movement at a speed that varies during one revolution and with an opposing relative rotation. Each support part supports a plurality of retaining devices arranged equally distributed along the circumference, wherein the retaining devices of the support parts are preferably arranged alternately and consecutively in the circumferential direction.

  • Patent number: 8453686
    Abstract: Tubes are directed to a filling station (15) for filling the tubes (T) in a tube-filling machine, and, in the filling station, a liquid or highly viscous product (P) is poured into the tubes by means of a filling apparatus (16). Each tube is also weighed and the actual weight is compared with a desired weight. The filling apparatus is adjusted if the variance between the actual weight and the desired weight lies outside predetermined limits. In the process, the weighing of the tubes in the tube-filling machine occurs within 5 sec. after the end of the filling operation, either already in the filling station or between the filling station and an ejection station (22) for bad tubes (T?).

  • Patent number: 8210546
    Abstract: A tube holder for a tube filling machine includes a cup-shaped housing having a tube receptacle that opens towards the top and into which one end area of a tube can be inserted. At least one vertical groove is formed in the area of the inner wall of the tube receptacle into which a clamping element is inserted, wherein the clamping element can be radially displaced substantially perpendicularly to the longitudinal central axis of the tube receptacle and is pivotably disposed about a pivot axis that extends substantially tangentially relative to the inner wall of the tube receptacle. A clamping force that acts radially from the outside onto the inserted tube can be applied by the clamping element under the action of upper and lower spring elements. The pivot axis is thereby formed on a pivot bearing which permits radial displacement of the pivot axis.

  • Patent number: 8056704
    Abstract: A method for controlling the transfer of a product stack in a packaging machine is provided, wherein the product stack is built up from a products during a work cycle and is subsequently transferred by means of a transfer apparatus (12) into a cell (18) of a continuously moved conveyor (16) during a transfer cycle. The product stack which is situated in the transfer apparatus and the cell of the conveyor assume a predefined relative position at least at the end of the transfer cycle. There is provision here for the movement speed of the conveyor to be changed in the event of an operationally caused lengthening of the work cycle and a resulting delayed start of the transfer cycle, in such a way that the cell or a following cell of the conveyor assumes the predefined relative position with respect to the product stack at the end of the transfer cycle.

  • Patent number: 7121065
    Abstract: A method for controlling a blister packaging machine during which a bottom film provided with a recess is, inside or in front of a sealing station, brought together with a top film and is guided through the sealing station at a constant speed of conveyance. A sealing roll, whose temperature can be controlled, is provided inside the sealing station and serves to seal the top film onto the bottom film. The speed of conveyance can be preselected in an at least indirect manner. When selecting a modified set value of the conveyance speed, the temperature of the sealing roll and the speed of conveyance are modified according to a predetermined characteristic curve until the predetermined set value of the speed of conveyance is reached.

  • Patent number: 7055296
    Abstract: A method for controlling a blister packaging machine has a work station which at least operates in cycles and which performs at least one first adjusting motion for a time period TV1 during one work cycle, followed by a treatment state for a time period TB, in which a product and/or material is treated. A second adjusting motion is then performed for a time period TV2 followed by a resting state for a time period TR. The time periods TV1, TB, TV2 and TR and a cycle rate R (=cycles/min) of the packaging machine are preset and at least the cycle rate R can be changed to a different cycle rate RV using an input device. A cycle time difference ?T which results from the changed cycle rate RV is substantially used to change the duration TR of the resting state. The time periods TV1, TB and TV2 preferably remain unchanged when entering a different cycle rate RV.

  • Patent number: 6931815
    Abstract: A packaging machine comprises a transfer device for inserting a product into a package and a circulating leaflet supply device comprising a plurality of tong-like holders which are sequentially disposed, each for receiving one leaflet and for bringing that leaflet into a region of the transfer device between the product and the package such that it can be inserted together with the product into the package. An opening unit with several stops, which can be actuated independently of each other, is disposed in the transport path of the holders for opening the holders to release the leaflet. The stops can be brought into an inoperative position in which the holders pass by the stops without releasing the leaflet. In this connection, the leaflet supply device comprises first holders to be opened by a first stop, and second holders to be opened by a second stop, and successive, sequential holders cooperate with and can be opened by different stops.
