A stacker (10) includes a housing (18) provided with an inlet port (20) and an outlet port (22), a tray (14) arranged beneath the outlet port of the housing in an upward/downward movable manner, and a transfer mechanism for transferring printed sheets from the inlet port to the outlet port and discharging the sheets above the tray through the outlet port. The sheet transfer velocity of the transfer mechanism is controlled in three stages including an intake speed (V.sub.1) at which the printed s...

A device for stacking flat, deformable, items contains a transfer device that accommodates individual items conveyed to it in receptacles and conveys them to a serializing device. At that transfer device, a row of compartments, into which the items are inserted, is conveyed transversely to the direction along which items' arrive. During insertion, items receive a velocity component in the compartments' direction of motion, while being brought to a standstill along their original direction of mot...

A stack (7) piled from a feed conveyor (3) can be transferred with stack definitions (15, 16) which can be lowered and optionally shifted in opposite directions to the left or right onto an exit conveyor (4 or 5), whilst the stack plies (6) continuing to be fed are intercepted by an auxiliary means (40, 50) and lowered onto the stack support (8) following return of the stack definition (15, 16) into the stacking position, as a result of which very simple and gentle exit transport of the stacks (...

A system comprised of trays is disclosed for converting a bucket to an organized receptacle for storing, carrying and dispensing tools and small parts or objects. Each of the trays is configured substantially as a modified circle so that it can be stacked neatly within the bucket. Each tray has partitions which divide the tray into compartments. Each tray has a partially recessed handle in the center of each tray in a configuration enabling them to be grasped readily by the fingers of a user, ev...

In a stacker, where a stopper for aligning the front end of the papers to be stacked being detachable within a bottom plate of a paper receiver by a magnetic force, a paper feed means being provided along the paper feed direction in a manner such that the feed surface projects slightly above the bottom plate, a projection being provided at the bottom of the stopper in a manner such that it extends in parallel with the feed surface while not projecting above the feed surface of the feed belt, the...

A stacker for a flexible strand, such as a flimsy wire, comprises: (a) a conveyor having an elongated endwise traveling stretch onto which the strand is fed to be carried endwise on the stretch, (b) a gripper to grip a trailing portion of the strand as forward extent of the strand is carried endwise on the stretch, (c) structure to effect displacement of the gripper to a position locating the gripped portion of the strand sufficiently out of alignment with the stretch that the strand is progress...

A press force control apparatus for use in a apparatus for stacking sheets of paper that have been cut from a continuous roll of paper by inserting each successive sheet of paper beneath a previously stacked sheet of paper. The press force control apparatus includes a paper press for pressing a top surface of the sheets of paper, after the sheets of paper have been placed in a stacked position, wherein the paper press is translatable up and down with respect to a stack height of the sheets of pa...

In a stacker for successively stacking cut papers on a bottom plate, a winding shaft for winding a non-cut continuous paper therearound is provided on a back side plate so as to project substantially perpendicularly to the paper restriction surface of the back side plate. This structure of the stacker makes it possible to stack the cut papers successively on the bottom plate and also makes it possible to easily wind the continuous paper around the winding shaft. In the stacker for successively s...

An improved stacker assembly includes a base assembly and a hollow mast which extends upwardly from the base assembly. A cap assembly is disposed on the upper end portion of the hollow mast. A carriage is movable up and down along the mast to raise and lower a load. The base assembly includes an upwardly extending mast support assembly which is telescopically received in the lower end portion of the hollow mast. The mast support assembly includes a gripper assembly which is operable to grip the ...

A bag stacker useful for plastic bags having a fence for stopping forwardly projected bags, raisable to permit a completed stack to move forward, a conveyor passing beneath the fence, a clamp moving with the conveyer to draw the completed stacks forward beneath the fence and a bag support arranged to assume, when the clamp engages a completed stack of bags, a position rearward of the fence, to receive and support bags arriving subsequently, this support being movable forward of the fence to dise...
