Abstract: A sheet stacking tray includes a first conveyor, a second conveyor, a sheet stopper, a first full-load detector, a second full-load detector, and a plurality of motors. The plurality of motors maintain the sheet stopper at a protruding position to block a sheet conveyed by the first conveyor until the first full-load detector outputs a signal indicating that a sheet bundle is fully loaded, shift the sheet stopper to a lowered position to allow the sheet bundle to pass when the first full-load detector outputs the signal indicating that the sheet bundle is fully loaded, drive the first conveyor and the second conveyor together to convey the sheet bundle when the sheet stopper shifts to the lowered position, and stop the second conveyor and drive only the first conveyor, when the second full-load detector detects a leading edge of the sheet bundle.

Abstract: A machine for inspecting, sorting and stacking items includes a plurality of conveyor lanes for moving items through the machine. An imaging system is arranged relative to the conveyor lanes to view items moving along the conveyor lanes. A reject arrangement is downstream of the imaging system and includes a plurality of selectively actuatable reject mechanisms, each reject mechanism associated with a respective one of the conveyor lanes enabling items to be selectively dropped from each conveyor lane on an individual lane basis. Items that pass inspection are conveyed to a downstream stacker, then on to item stack conveyors before being moved onto a side transfer conveyor. A controller analyzes image data to make a determination of whether any item is below a defined quality threshold and, if so, to control the reject mechanism to drop the below quality item out of the conveyor lane.

Abstract: A method for the quick palletization of objects (100), comprising the steps of: arranging objects (100) to be palletized organized on a collection plane (400); loading said objects (100) onto a flexible support plane (31) suitable for advancing in the direction of transfer of the objects (100) in a position substantially coplanar to the collection plane (400) and in continuation of it, so that the support plane (31) receives said objects without sliding; transferring said objects (100) from the support plane (31) to a flexible moving plane (21) that can slide coplanar to the support plane (31) so as to replace the latter (31) below the objects (100) whilst they remain stationary, in which the transfer takes place by synchronously activating the harmonious sliding of the support plane (31) and transfer plane (21) arranged in contact with each other in continuation of one another; taking the transfer plane (21) with the objects (100) on top above a pallet; making the transfer plane (21) slide under the objec

Abstract: A method is provided for automated converting of a web of a thin patterned catalyst-coated membrane to separate membrane sheets for fuel cell assembly. The membrane typically has a thickness of about one thousandth of an inch. Automated web converting involves transporting, with use of a movable vacuum, an end portion of the membrane web from a first location to a second location. With use of respective first and second vacuums at the first and second locations, and after removal of the movable vacuum, the end portion of the membrane web is releasably secured at the first and second locations. The membrane web is cut within a gap defined between a single catalyst pattern of the membrane web end portion and an adjacent catalyst pattern to produce a membrane sheet. The membrane sheet is precisely positioned to a desired orientation to facilitate subsequent processing of the membrane sheet.

Abstract: One embodiment of the invention is a method for placing circuit boards in a receiving container, comprising the following steps: a) gripping and lifting a circuit board with a first grappling device, b) moving the first grappling device and the receiving container relative to each other, such that the receiving container is located below the first grappling device, c) the first grappling device lowers the circuit board into the receiving container, d) gripping and lifting a partition layer from a dispenser with a second grappling device, e) reversion to step b), such that the receiving container is accessible from above and is below the second grappling device, f) the partition layer is placed in the receiving container on top of the previously placed circuit board and g) start the process at a).

Abstract: In a signature-stacking apparatus, a conveyor chain holding a row of signatures travels along a conveyance path. A first signature release section and a second signature release section are provided in the conveyance path. During travel from the first signature release section to the second signature release section, the conveyor chain is twisted by 180 degrees about the direction of travel and makes a 180-degree turn about an axis parallel to a connection pin of the conveyor chain. Signatures released from the first and second signature release sections are conveyed to first and second signature delivery sections disposed on opposite sides of a stacking section by first and second conveyor mechanisms while their speed of conveyance is being adjusted. A predetermined number of signatures are delivered, while being led by their creases, into the stacking section from the first and second signature delivery sections alternately.

Abstract: A counter-stacker includes an infeed conveyor having a plurality of lanes for containing planar food articles. A vacuum conveyor system is located adjacent to the infeed conveyor and includes a plurality of vacuum conveyors. Each vacuum conveyor includes a frame, a pair of pulleys rotationally mounted to the frame, a drive shaft coupled to one of the pair of pulleys, a vacuum generator for generating vacuum conditions within the frame, and a vacuum belt mounted to the pair of pulleys. Each vacuum conveyor is pivotable about one of the pair of pulleys. An oscillating catch cup frame containing a plurality of catch cups is used to stack the planar food articles.

Abstract: The apparatus (10) serves for transporting and stacking goods (12), in particular in the form of plates such as metal plates or the like, and includes a feed transport device (14), which is connected to a stacking device (16). In this apparatus an overhead transport device (18) is provided which is disposed at least partially in a stacking area (20) above the stacking device (16) and which has a holding system (22) which can be activated and deactivated, where a delay system is provided for time-delayed activation of an effective holding force of the overhead transport device at a point in time when the front, seen in the direction of transport, area of the goods overlaps the stacking area in the direction of stacking.

Abstract: A counter-stacker (10) for tortillas includes a housing (12), a perforated belt (16) within the housing (12), the perforated belt (16) adapted and arranged to receive incoming tortillas (42) and form vacuum-lifted tortillas (42A). At least one stacker belt (26) is rotatably mounted within the housing (12). A vacuum housing (28) is sealably mounted to the housing (12), the vacuum housing (28) connected to a means of producing vacuum (30). At least one stacker canister (32) is positioned under a rear end of the perforated belt (16). A bottom perforated plate (36A) has a plurality of bottom perforated plate openings (36AA) therethrough positioned within the perforated belt (16). A top perforated plate (36B) is slidably positioned on top of the bottom perforated plate (36A), the top perforated plate (36B) comprising a plurality of complimentary positioned top perforated plate openings (36BA).
