1. Device for stacking stackable material, especially mineral fibreboard (21) in a production line, in layers (22), arranged one above the other, consisting of one or more articles, a) with a lifting device (24 or 25) for layers (22) of the articles for vertically displacing the layers (22) when the stack is being formed, b) with a fixed, lower stack support surface (30), c) with a stop (47), arranged in the entry direction of the layers (22) and behind the stacking space (23), for a recorded stoppage of the respective new layer (22) entered, and d) with a conveyor device (rollers 45, delivery belt 20) for conveying away the prepared stack, e) with supporting elements, working in an aligned manner for the lifting movement at least approximately parallel to the stack support surface (30), for the layers (22) being provided in the form of fork arms (41, 42 and 43, 44), which can be moved in from the side under the stack and, after lifting has been effected, can be moved out again from the stacking space and f) with the lifting device (24 or 25) having sets of fork arms (41, 42 and 43, 44), which are arranged on both sides of the stacking space (23) and can be driven synchronously in opposite directions in the horizontal direction and in the same direction in the vertical direction, and each of which reaches less than half way across the width of the stack support surface (30), characterised in that, g) two lifting devices (24, 25) are provided, the respective fork arms (41, 42 and 43, 44) of which are retained relatively moveable in the vertical direction relative to those of the other lifting device (25, 24), h) the fork arms (41, 42 and 43, 44) of both lifting devices (24, 25) are mounted by means of distance pieces (37, 38, 39, 40), at a distance corresponding to at least the lift height (h1 ) of the working stroke, in the case of one lifting device (24) at the upper side of lower layer portions and in the case of the other lifting device (25) at the lower side of upper layer portions of the associated lifting device (24 or 25), and i) the fork arms (41, 42) of one lifting device (24), relative to the fork arms (43, 44), located on the same side of the stacking space (23), of the other lifting device (25), are offset laterally to an extent anabling the fork arms to run past one another vertically, and pass through the latter during the relative vertical movement. |
