Patent ID: 8613585

Claim:
An arrangement for the stacking in layers of timber packages, comprising a transfer arrangement, the transfer arrangement comprising several individual carrier planes that are mobile one after the other around a cyclic path arranged to transfer one layer at a time from an input transporter to a stacking table that can be raised and lowered, whereby the transfer arrangement is so arranged at the delivery end of the input transporter 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layer from the input transporter and displace the layer in over the stacking table, after which the carrier planes are withdrawn from the stacking table while the layer of timber is scraped off from the carrier plane through interaction with a counterpiece arranged at the stacking table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, wherein the transfer arrangement comprises a first, a second and a third carrier plane, which are individually movable by a respective drive and arranged to move cyclically in such a manner that a pair of two consecutive carrier planes is located at the same time in a position directly above the stacking table and that the carrier plane of the said pair that has arrived at the stacking table most recently is retained in its position above the stacking table while the carrier plane of the pair that arrived at the stacking table first is withdrawn from the stacking table while the layer is being scraped off.
