Abstract
Abstract A holder which is turnable about a horizontal axis supports two carriers for filled or empty trays. The holder moves one carrier with a filled tray therein from a first station to a second station where the carrier deposits the filled tray, in inverted position, on top of the magazine of a packing machine, while the other carrier moves back from the second to the first station. The carriers are pivotable relative to the holder so that a carrier with a filled tray therein can descend on top of the magazine during the last stage of movement to the second station and that the carrier with an empty tray therein is lifted above the magazine during the initial stage of its movement from the second station. This is achieved by connecting the carriers to links which are pivoted directly to the holder or to a lever which is rotatable by a shaft eccentrically mounted in the interior of a hollow cylinder serving to turn the holder.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
214 words
Apparatus for transporting filled trays from a first station to a second station at which a filled tray is located on top of a magazine and its contents are transferred into such magazine, and for thereupon transporting the thus obtained empty trays from said second station back to said first station, comprising holder means turnable about a substantially horizontal axis; first and second carriers turnable with said holder means and each arranged to temporarily store a filled tray or an empty tray; means for turning said holder means about said axis to thereby invert that one of said carriers which moves with a filled tray therein from said first to said second station and to simultaneously return to non-inverted position the other carrier which moves with an empty tray therein back to said first station; and means for pivoting said carriers relative to said holder means while said holder means turns to move the carriers between said stations, said pivoting means including means for lowering an inverted carrier with a filled tray therein on top of said magazine during the last stage of movement to said second station and for lifting such carrier with an empty tray therein off the top of the magazine during the initial stage of movement from said second station.
Claim 2
Dependent Claim
214 words
Apparatus for transporting filled trays from a first station to a second station at which a filled tray is located on top of a magazine and its contents are transferred into such magazine, and for thereupon transporting the thus obtained empty trays from said second station back to said first station, comprising holder means turnable about a substantially horizontal axis; first and second carriers turnable with said holder means and each arranged to temporarily store a filled tray or an empty tray; means for turning said holder means about said axis to thereby invert that one of said carriers which moves with a filled tray therein from said first to said second station and to simultaneously return to non-inverted position the other carrier which moves with an empty tray therein back to said first station; and means for pivoting said carriers relative to said holder means while said holder means turns to move the carriers between said stations, said pivoting means including means for lowering an inverted carrier with a filled tray therein on top of said magazine during the last stage of movement to said second station and for lifting such carrier with an empty tray therein off the top of the magazine during the initial stage of movement from said second station.
