An automatic machine for stacking objects, as metal ingots, having a loading unit with a movable carriage operable to carry ingots to an ingot collector and holding unit. The ingots are collected on movable supports located above a rotatable elevator platform. On movement of the supports to the open positions, the ingots are transferred to the elevator platform or the top layer of ingots carried by the elevator platform. Consecutive layers of ingots are normally disposed with respect to each other by rotating the elevator platform after each layer of ingots is transferred to the top layer of ingots. The complete stack of ingots is pushed with a hydraulic ram from the elevator platform onto a roller stack conveyor.
A conveying system for transversely conveying logs has two conveyors which are arranged sequentially. The first conveyor has two or more transversely spaced guides each having a first portion which is upwardly inclined in the conveying direction and a second portion downwardly inclined from the downstream end of the first portion, also in the conveying direction. A second conveyor is similar to the first conveyor and its first portion receives conveyed logs from the second portion of the first conveyor. Engaging or conveying elements are mounted on these guides for movement in the conveying direction and for return movement, and each of these elements can be individually advanced at a rate which can be selected for it and in forward or reverse direction, independently of the others.
A plurality of bottles (125) or other containers are delivered and aligned under a plurality of filler heads (110) each having a liquid feed channel (113) extending vertically downward to outwardly opening apertures (119) and also an inert gas feed channel (116) extending vertically downward to a lower end (117) below the apertures (119). The bottles (125) are moved upward (134) and chemicals are delivered into the bottles (125) through the liquid feed channel (113) and apertures (119). When the liquid level (127) of each bottle reaches the lower end (117), the back pressure in the inert gas feed channel (116) is sensed (123) and the liquid flow is shut off (120). Contamination of the bottles by particulates is minimized since no moving parts are required above the level of the bottles and because no contact is required between the filler heads and the bottles.

An article stack unifying device having article stacking elements is provided to stack a plurality of articles on a surface on or of a rotatable surface. While the articles are being stacked on the selected surface a quantity of wrapping film is wrapped around the stack of articles at intervals during the stacking process and at the completion of the stack.
An apparatus is provided for organizing and arranging bundles, preferably bundles of folded or unfolded corrugated boxes or blanks, into stacks which include a plurality of layers. The apparatus includes a vertical conveyor for supplying bundles to a loading station, at which one or more operators or mechanical arms are located, which function to remove the bundles for the loading station and to position them in a desired pattern on a horizontally movable support to form a layer. After a complete layer is formed, the support is removed from beneath the layer so that the layer of bundles is deposited on a stack-forming device which includes a vertically movable platform which is incrementally actuated downwardly each time another layer is deposited thereon to form the stack. The formed stack is then discharged from the stack-forming device and straps are applied thereto. Actuating means are provided for removing the support from beneath each formed layer and for lowering the stack-forming device after the stack is formed. The output of the actuating means is supplied to a programmer which in turn regulates the speed of the vertical conveyor to control the rate of supply of bundles to the loading station so that it is synchronized with the rate at which bundles are arranged into layers to form stacks to thereby avoid jam-ups or slow-downs in the system.
