The invention relates to an apparatus and a method for marshalling out individual objects ( 1 ) from a row of such objects ( 1 ). The apparatus includes two pusher arms ( 8 ) placed one on each side of the row of objects ( 1 ). The apparatus also includes two arrest pins ( 20, 21 ) on either side of the row, one front ( 20 ) and one rear ( 21 ). The apparatus further includes a linkage ( 13 ) on each side of the row, axially connected to a pusher arm ( 8 ) and interconnected with each other via a spring ( 14 ), respectively. The pusher arms ( 8 ) are moved, in a closed position, forwards with the aid of a piston and cylinder assembly ( 19 ) and, in this movement, marshal out the first object ( 1 ) in the row. Thereafter, the pusher arms ( 8 ) open in that they enter into abutment against the front arrest pin ( 20 ). The linkage ( 13 ) ensures that the pusher arms ( 8 ) assume an open position. The pusher arms ( 8 ) thereafter move backwards in the open position with the aid of the piston and cylinder assembly ( 19 ). When the pusher arms ( 8 ) enter into abutment against the rear arrest pin ( 21 ), they begin to close and the linkages ( 13 ) ensure that the pusher arms ( 8 ) assume a closed position, whereafter the operational cycle may be repeated. |
