Abstract
The invention relates to 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.
Abstract
A blister packaging machine comprises a filling station, in which products can be inserted into cup-shaped depressions of a bottom sheet, and a downstream sealing station in which a supplied cover sheet is sealed onto the bottom sheet thereby forming a blister band. The cyclically operating sealing station has an associated cyclically operating first drive device for discontinuously transporting the bottom sheet and the cover sheet through the sealing station. A second drive device for the bottom sheet is thereby disposed between the filling station and the sealing station for discontinuously transporting the bottom sheet. The drive motions of the first drive device and the second drive device are superposed such that the bottom sheet is transported on the stationary filling station at a constant speed.
Abstract
The invention concerns a method for controlling a blister packaging machine having a work station which at least operates in cycles and which performs at least one first adjusting motion for a time period T.sub.V1 during one work cycle, followed by a treatment state for a time period T.sub.B, in which a product and/or material is treated. A second adjusting motion is then performed for a time period T.sub.V2 followed by a resting state for a time period T.sub.R. The time periods T.sub.V1, T.sub.B, T.sub.V2 and T.sub.R 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 R.sub.V using the input means. A cycle time difference .DELTA.T which results from the changed cycle rate R.sub.V is substantially used to change the duration T.sub.R of the resting state. The time periods T.sub.V1, T.sub.B and T.sub.V2 preferably remain unchanged when entering a different cycle rate R.sub.V. |
