A stacking plant and method for stacking elongated bodies such as timber bodies in layers situated one above the other wherein all of the bodies of all of the layers are substantially parallel to each other with adjoining layers being separated by at least a pair of laths which extend crosswise of the bodies. A body-handling apparatus is arranged so as to extend along a first location while a lath-handling apparatus is arranged so as to extend along a second location part of which extends across the first location, both of these apparatus being operated in such a way that the body-handling apparatus sequentially forms at the intersecting parts of the locations layers of the bodies while the lath-handling apparatus deposits on each layer at the intersecting parts of the locations at least a pair of laths after each layer is formed and before the next layer is deposited on the laths situated on the preceding layer by the body-handling apparatus. The above first and second locations have elongated portions which extend in the same general direction and between which there is located at a third location a station for a single operator who can control both the body-handling apparatus and the lath-handling apparatus while having a good visibility of all of the operations.
In a method for arranging elongated bodies, such as timber bodies, in a stack wherein all of the bodies are substantially parallel to each other and respectively situated in several layers situated one above the other with at least two laths situated between each pair adjoining layers of said elongated bodies, extending crosswise thereof and maintaining a space between the adjoining layers, the steps of operating at a first elongated location a body-handling apparatus which has opposed ends and sequentially forms from said bodies a series of layers thereof situated one above the other, operating at a second elongated location which in part extends across a part of said first location a lath-handling apparatus which situates on each layer of said bodies formed by said body-handling apparatus before the next layer is situated thereon, at least a pair of laths spaced from each other and extending across the bodies of each layer, the next layer of said bodies being deposited by said body-handling apparatus on the laths situated on the preceding layer of said bodies by the lath-handling apparatus, and controlling the operations of said body-handling apparatus and lath-handling apparatus by a single individual situated at a third location spaced at a substantial distance from the crossing parts of said first and second locations, situated substantially midway between said ends of said body handling apparatus and between said first and second locations, and from which said first and second locations are conveniently visible.
In a plant for forming from elongated bodies such as timber bodies and from elongated laths stacks of said bodies wherein the bodies are arranged in several layers situated one above the other with all of the bodies and all of the layers being substantially parallel to each other and with at least a pair of laths situated between each pair of adjoining layers extending crosswise of said bodies to space said layers from each other, elongated body-handling apparatus having opposed ends situated along a first location for forming from a plurality of said bodies at a given part of said first loc action a series of layers of said bodies which are situated sequentially one above the other by said body-handling apparatus, elongated lath-handling apparatus extending along a second location a portion of which extends in the same general direction as a portion of said first location, and one of said locations extending in part across the other at the part of said first location where the layers are sequentially formed by said body-handling apparatus, said lath-handling apparatus depositing at least a pair of laths on each body layer formed by said body-handling apparatus after each layer is formed thereby and before the next layer of said bodies is deposited by said body-handling apparatus on the laths deposited by said lath-handling apparatus on the immediately preceding layer of said bodies, and an operator control station for a single operator situated at a third location between said elongated portions of said first and second locations which extend in the same general direction at a substantial distance from said crossing parts of said locations, substantially midway between said ends of said body-handling apparatus for providing for the single operator control of both the body-handling apparatus and the lath-handling apparatus while at the same time providing for the single operator a good visibility of the operations carried out by both the body-handling apparatus and the lath-handling apparatus.
