The invention concerns a method and an arrangement for the stacking in layers of timber packages (8') that uses a transfer arrangement consisting of several individual carrier planes (5, 6, 7) that are mobile one after the other around a cyclic path and which, for the transfer of one layer (20, 21, 22) at a time from an input transporter (1) to a stacking table (8) that can be raised and lowered, are arranged in direct association with a delivery end (3) of the input transporter such that the carrier planes in turn form a direct continuation of the input transporter in order to receive layers fed from this transporter by being caused to lift from below a complete layer from the input transporter and displacing the layer in over the stacking table (8), after which the carrier planes are withdrawn from the stacking table while the layer of timber is scraped off from the carrier plane through interaction with a counterpiece (23) arranged at the stacking table such that the layer is laid directly onto the carrier arms of the stacking table or, when a layer has previously been laid onto these arms, onto the uppermost layer of timber whereby the stacking table is arranged to move downwards in steps with the growth of the timber package to a corresponding degree until the package has been completely formed. The transfer arrangement uses, in order to increase its capacity, a first, a second and a third carrier plane (5, 6, 7) which are arranged to move mutually in a cycle in such a manner that one pair of two consecutive carrier planes (5, 6) is located at the same time at a position above the stacking table (8). |
