摘要:
An apparatus for the sterile packaging of foods, for instance dairy products or the like, in cup-shaped previously-shaped containers, which comprises an endless conveyor chain adapted to carry cup-shaped finished containers along an upper and a lower pass. A filling station, a lid-application station, a sealing station, and an ejection station are provided. The containers are conveyed in succession past the stations. The apparatus has housing means which extends over at least the entire conveyor chain as a self-enclosed sterile chamber free of drive means. At least one-half of the length of the conveyor chain in front of the filling station is juxtaposed with a discharge mouth of a finished-container magazine opening directly into the sterile chamber. Immediately adjoining the sterile chamber is a sterilizing-agent spray station which provides a sterilizingagent path of action corresponding at least to the length of the lower course of the conveyor chain. A nozzle pipeline system is provided over the entire length of the sterilizing-agent path of action. The nozzle pipeline system is fed optionally with a sterilizing agent and with sterile drying air, respectively, and is located in a plane below the conveyor chain. The sterile chamber is subdivided into partial lengths along the upper course of the conveyor chain in the region on the sterile-chamber side of the filling, lid-applying and sealing stations by a screening provided with its own additional pressure-producing sterile-air feed and its own outlet.
摘要:
An apparatus for continuous adjustment of the working stroke of a driving machine, wherein the adjustment of the working stroke is simplified and rendered easier. A stroke adjustment spindle, mounted in a crank ring which is rigidly connected with a driven crank hub, in addition to manual operation, is further adjustable by an adjustment drive, preferably by a bevel gear drive, movable selectively in one or in the other opposite rotary adjustment direction. This adjustment is brought about by sitting the driving or control wheel of this double gear drive at one end of a control shaft, projecting axially through the driven crank hub and likewise driven with the latter, which control shaft is coupled for a joint drive at its counter end and is as well axially slidable on the latter. The control shaft receives an engaging element operable from the outside by means of an engaging lever arrested in the rest position and manually operable, which engaging element, depending upon the amount of the stroke adjustment, cooperates either with a coupling ring disc immovable in space, preferably on the side of the coupling housing, and disposed with an axial distance, for instance, on the left side from the engaging element, in the sense of a rotary locking of the double gear drive control shaft, or is provided with a second coupling ring disc disposed with an axial distance, for instance, on the right side from the engaging element, by means of an additional transmission drive driven from the crank hub with a peripheral speed higher than that of the crank hub in the sense of a bevel gear drive control shaft drive with its own driving speed surpassing the peripheral speed of the crank hub.
