Abstract:
A method and apparatus are disclosed for imparting a desired shape to a paperboard blank. The blank is formed between two dies for a sufficient length of time and with sufficient force to set the form, while moving the dies in tandem along a predetermined portion of a reciprocation path. Because the formed blank remains in dwell while the dies are moving in tandem, it is not necessary to hold the dies stationary to ensure permanent formation of the blank. This allows greater production speeds.
Abstract:
In an apparatus for coiling flat workpieces arriving in overlapping formation on a conveyor onto a winding core to form a reel of overlapping workpieces, a pivoted frame carrying rollers for an endless driven belt is mounted so that the belt lies initially against the winding core and then against the convolutions of workpieces being coiled thereon. The frame is mounted on a pivot shaft which subdivides the frame into differently long lever arms, each carrying a roller for the belt. The ends of the winding core are mounted in parallel guides extending substantially along imaginary lines passing through the winding core axis and the axis of the roller on the shorter lever arm.
Abstract:
A conveyor apparatus for stacked articles, such as stacked plastic or paper bags, includes a frame, and a plurality of sprocket assemblies about which one or more conveyor chains extend. The apparatus includes a plurality of wicket wire holding assemblies mounted on the chains at spaced apart intervals for intermittent, incremental movement along a conveyor path defined by the conveyor chains. Each of the holding assemblies includes a pair of support arms, and an adjustment mechanism for adjusting the spacing between the arms. The apparatus includes an arrangement for simultaneously adjusting the spacing between the support arms of all of the holding assemblies, including an adjustment drive chain trained about the sprocket assemblies, and a mechanism for moving the adjustment drive chain relative to the conveyor chains of the apparatus.
Abstract:
A carton folding apparatus which is characterized by multiple folder/gluer modules, including a feed module for receiving and delivering unfolded cartons, prefold/fold, fold and final fold modules for effecting specified folding and gluing operations, a delivery module for completing the folding operations and further including a stacker unit for receiving and stacking the folded and glued cartons. Each of the folder/gluer modules is capable of being removed from the apparatus line and is characterized by separate, independently driven upper and lower belt feed mechanisms for driving the cartons through that module. The feed module includes adjustable upper and lower feed assemblies and the remaining prefold/fold, fold, delivery and final fold modules include upper and lower carriages, which upper carriages may be adjusted upwardly with respect to the feed assembly and bottom carriages, respectively, and both carriages in the prefold/fold, fold, delivery and final fold modules are laterally adjustable to accommodate cartons of various width. While the respective belts in each of the folder/gluer modules are independently driven, all belt drive motors are synchronized to insure that the belts operate at the same speed. The belt-carrying mechanisms in all of the folder/gluer modules are designed to facilitate optimum belt replacement without the necessity of dismantling the carrying mechanisms.
Abstract:
Apparatus is disclosed for stacking bundles such as bundles of paperboard sheets on a receiver. The apparatus includes an L-shaped conveyor having a top run and a bottom run. The top run of the conveyor has a position defined by the location of spaced first and second carriers having discrete guide members contacting the conveyor. The carriers are individually elevated with the second carrier being progressively elevated in stages while the first carrier moves up and down from a receiving position to a position corresponding to the current position of the second carrier.
Abstract:
An improved stop plate and belt assembly for the stacking section of a corrugated box machine and an improved system for conveying corrugated boxes from the folding section to the stacking section of a corrugated box machine.
Abstract:
Apparatus for the head-to-tail stacking of objects or groups of objects, such as folded cardboard packaging boxes, which are substantially identical in terms of their shapes, their dimensions and the orientation with which they are presented to the apparatus. The apparatus includes an aligning and retaining device which is mounted on a shaft extending above and transversely with respect to a conveyor. The aligning and retaining device is arranged to remove and invert a first batch of objects at the same time as abutments position a second batch below the first batch. The first batch are then laid on the second batch to form a stack.
Abstract:
An apparatus for forming a regular stack of folding boxes wherein each box has unequal thicknesses at the end portions thereof. The apparatus has a conveyor belt for feeding the boxes and an upper and lower stacking station situated on two different planes. The boxes are fed from the conveyor belt only to the upper stacking station to form a partial stack thereon with light thickness ends in superposition. The partial stack from the upper stacking station by disposing a turntable from the lower stacking station vertically beneath the upper stacking station, providing displaceable floors in the upper stacking station to enable passage of a partial stack vertically downwardly to the turntable and mounting the turntable for rotation about a vertical axis to effect the stacking of successive partial stacks thereon with unlike thickness ends in superposition.
Abstract:
A corrugated cardboard box stacking device in a corrugated cardboard box making machine wherein the space for stacking manufactured and folded corrugated cardboard boxes is divided into two of lower and upper spaces of a corrugated cardboard box storing space and a corrugated cardboard box stacking space which is positioned above and a little ahead of the storing space, and the uppermost cardboard box of a group of stacked corrugated cardboard boxes is moved by a kicker one by one to the corrugated cardboard box stacking space where a group of the corrugated cardboard boxes are moved at once to a delivery belt by a pusher bar when the number of the boxes have reached a predetermined number. The pusher bar does not affect the group of the corrugated cardboard boxes stacked in the storing space and an exact number of a group of the corrugated cardboard boxes in the stacking space can be moved at once to the delivery belt and the like.
Abstract:
A cartoner has a side seam gluer for forming flat folded cartons which are vertically oriented in a magazine for feeding into the cartoner. A conveyor having a horizontally-movable discharge chute feeds the flat folded cartons in a vertical orientation onto the feeder. The discharge chute moves horizontally to follow the increasing or decreasing supply of cartons and permits the accumulation of a supply of cartons sufficient to run the cartoner for about two minutes in the event of a jam in the side seam gluer.
