| 摘要 | A machine for automatically taking articles from a single starting stack and depositing them on an alternate basis in two separate stacks. The machine includes means for advancing a single article from the starting stack cooperating with separating means, the latter constituting a pair of intercooperating, pivotable arms provided with article gripper heads and article stripping means located relative to separate stacking sites positioned effectively of the travel arc of each of the pivotable arms. | ||||||
| 权利要求 | 1. A machine adapted to automatically separate articles from a starting stack of the articles into two separate stacks on an alternate basis comprising article advancing means for advancing articles in a longitudinal path singly from the starting stack, separating means comprising a pair of arms pivotably mounted about spaced vertical axes, each arm being provided with article gripper means for releasably gripping articles moving along said longitudinal path of advance and adapted to arcuately travel in a horizontal plane and transfer said articles on an alternate basis to opposed laterally spaced stacking positions, means for moving said pair of arms about their said pivot axes, and article stripper means positioned effectively within the travel arc of each of said pivotable arms and above said laterally spaced stacking positions for stripping articles from said gripper means so the articles fall and are stacked therebelow. 2. A machine according to claim i wherein the means for advancing the articles from the starting stack is a reciprocally movable plate which advances the bottom article in the starting stack. 3. A machine according to claim 2 wherein a gate means is provided in the direction of advance of the articles from the starting stack, the gate defining an opening having a height dimension through which only a single article can pass at one time. 4. A machine according to claim 1 wherein the pivotable arms are interconnected through a doubly pivotable connecting member. 5. A machine according to claim 1 wherein the article gripper members include spring loaded jaws which are adapted to be forced apart by an article directed into same by the article advancing means. 6. A machine according to claim 1 wherein the stripper means includes separate abutment members spaced apart a distance less than the effective length of the article presented to the same by the article gripper means. |
