  • Patent number: 4941562
    Abstract: The invention comprises an arrangement for transporting articles, in particular rectangular box-like packages into a single or plural paths packaging machine by at least one slider and a guiding flank. The arrangement includes a combined turning and collecting arrangement for the articles, respectively packages. The guiding flanks of this arrangement define the curved guiding paths which includes curved flanks which extend essentially angularly with respect to the transport direction and further include guide grooves which coact with the slider. By this arrangement, the articles, respectively packages are slidingly fed, turned and collected.

  • Patent number: 4930288
    Abstract: The invention relates to an improved sealing head for sealing a cover made of a foil material onto a packaging container, in particular a plastic cup. The sealing operation is carried out by means of a heatable sealing head. This sealing head includes an insulating body which provides for the compensation of form and position deviation between the sealing head and the plastic cups which are to be sealed. This insulating body simultaneously provides for the thermal insulation between the sealing head, on the one hand, and the drive arrangement, on the other hand. Thereby a flaw-free sealing is achieved and any down-times due to malfunctioning of the arrangement are substantially reduced.

  • Patent number: 4915208
    Abstract: The invention relates to a process and arrangement for exchanging cellular members which are provided with container receiving openings and form part of a filling machine. The cellular members are successively removed from the filling machine and cellular members with an alternate format for receiving containers are essentially simultaneously inserted into the filling machine. This operation is carried out in that an exchange arrangement receives the first formatted cellular members at a first receiving station of a magazine and dispenses alternately formatted cellular members at a second working station of the machine is disposed at a distance from the afore-mentioned receiving station. In this manner it is possible to carry out a cellular member exchange in a very rapid manner and by a very simple process and arrangement.

  • Patent number: 4860926
    Abstract: The invention relates to an arrangement for dosingly filling pasty or fluid filling material into containers. The arrangement is provided with a rotatably mounted cylinder and an axially slidably mounted piston which moves within the rotatable cylinder and which in its extreme inner position closes at least a third, but preferably about 50% of a window-like through opening, respectively inlet opening in the housing of the device. When retracting the dosing piston it exposes the portion of the through opening which has been closed when the piston is in its innermost position. By filling containers by means of the device of this invention, the filling material is automatically dropped into the rotating cylinder and is thereby subjected to an extraordinarily sparingly sensitive manipulation, which is particularly significant for sensitive products, such as for example salad-like products.

  • Patent number: 4750531
    Abstract: An automatic exchange device for format dependent cellular panels used in container-filling machines for filling containers with foodstuffs, flavorings or other liquid to pastiform products, the machines being arranged to pick-up and transport the containers whereby cellular panels are arranged adjacent to each other on a through-conveyor or periodically circulating conveyor and are corrected to the conveyor. A replacement mechanism for the cellular panels. The exchange of panels is effected with the assistance of a manipulator, which automatically detaches the connection with the assistance of a motor driven screw tool and also reattaches the connection after the exchange. After releasing the connection, the manipulator picks up the cellular panel by means of suction cups and removes it via the use of an elevator into a magazine, which, for example, is comprised of a drum with radially arranged partitions.
