Abstract:
A sheet processing apparatus includes a vertically movable tray that moves vertically in accordance with an amount of stacked folded sheets which are transported and stacked thereon, a plate that is disposed above the vertically movable tray and that does not move in accordance with transport of a folded sheet, a recognizing unit that recognizes a predetermined height state of a sheet stacked on the vertically movable tray, and a controller that controls the vertically movable tray so as to, in response to a recognition of the predetermined height state of the sheet by the recognizing unit, move the vertically movable tray upward, press the sheet stacked on the vertically movable tray against the plate, and subsequently move the vertically movable tray downward.
Abstract:
A pillow block supporting a feed roller includes a pillow block main body; a wedge body adjusting a height position of the pillow block main body; and a bracket adjustably installing the pillow block main body in a sheet feeding direction on a mounting surface. Further, the pillow block main body includes a reception part to support the feed roller, a concave part though which the wedge body is inserted, and the bracket is temporarily fixed to the mounting surface. Further, the wedge body pushes up the height position of the pillow block main body upon being inserted into the concave part to determine the position of the reception part so that the reception part supports the feed roller from below.
Abstract:
A sheet take-out device in which sheets are conveyed in an upright state and sheets having a low height can be stably taken out is provided.A sheet take-out device includes a main floor belt that conveys sheets that are placed in an upright state in a direction intersecting a conveying direction to a take-out portion, and a take-out unit that takes out the sheets conveyed by the main floor belt one by one in order from the frontmost sheet. The device includes a sub-floor belt that is capable of reverse conveyance, in which sheets are conveyed in a direction opposite to the conveying direction of the main floor belt, a tightness detection unit, and a height detection unit that detects the height of the sheets immediately prior to being taking out by the take-out unit, and performs sub-floor control.
Abstract:
A sheet processing apparatus and method of adjusting a vertical position of a sheet input of a sheet processing apparatus includes a support of the apparatus having first vertically elongated guiding members and second vertically elongated guiding members. The second guiding members are slideably arranged at the first guiding members. The first guiding members are connected to at least one base member, and the second guiding members are connected to a support frame. A vertical position of at least one of the second guide members is adjustable relative to a corresponding one of the first guide members in order to adjust a vertical position of the sheet input.
Abstract:
A sheet surface detecting mechanism, which detects the upper surface of sheets stacked on a tray, including: a sensor disposed in a position spaced apart from a conveying portion; a pivotal sensor flag turning the sensor ON/OFF; and a sheet surface detecting member being disposed in parallel with the sheets stacked on the tray, moving in a vertical direction while causing the sensor flag to pivot in contact with the upper surface of the sheets, and turning the sensor ON/OFF via the sensor flag.
Abstract:
A machine and method is disclosed for stacking product, including but not limited to, cardboard, magazines, newspapers, newspaper supplements, flyers, press signatures, and softcover books. The stacking machine includes an infeed assembly for receiving a product stream or flow. The infeed assembly includes a belt jogger assembly for aligning product as it enters the machine. A transport assembly delivers product from the infeed assembly to a stacking assembly. The stacking assembly includes an interrupter that creates a gap in the product stream and assists in accumulating a single lift of product on a separator. The separator delivers a single lift of product to one of a pair of elevators, which deliver a first application of compression to the lift. After the first compression, the lift is transferred to a compression apparatus where a second round of compression is applied in the process of forming a final stack. Each time a lift is delivered to the compression apparatus, compression is applied to the stack, thus many of the lifts will be compressed several times until the stack is ejected from the machine.
Abstract:
A plate feed apparatus has a cylindrical pick-up head having a predetermined number of pick-up units. The pick-up head rotates with a first shaft at a first rotational speed. A feed mechanism places the uppermost plate in a stack of plates a nominal distance from the periphery of the pick-up head when a plate is removed from the stack. A vacuum is selectively drawn through each pick-up unit to pull the outermost plate into contact with the pick-up unit. A second shaft has a cylindrical bore which rotatably journals the first shaft and is offset from the centerline of the second shaft. The second shaft is rotated counter to the first shaft at a speed which is a multiple of the speed of the first shaft equal to the number of pick-up units. This causes the speed of the pick-up unit to be slower and its distance from the uppermost plate in the stack less each time a pick-up unit picks up a plate. The number of pick-up units and the diameter of the pick-up head are established relative to the size of the plates such that plates overlap one another on the pick-up head. An outfeed conveyer has a higher surface speed than the pick-up units so that the plates do not overlap on the outfeed conveyer. The feed mechanism places another stack of plates under the stack of plates before the stack becomes depleted.
Abstract:
A sheet material conveying apparatus includes a plurality of sheet material feeders. A plurality of pockets are movable past each of the sheet material feeders in turn to sequentially feed sheet material into the pockets. Each pocket has an upper end portion through which sheet material enters the pocket, a lower end portion through which sheet material leaves the pocket, and a support which supports sheet material in the pocket. The support is movable between a plurality of closed positions in which the support is spaced different distances from the upper end portion of the pocket and at least partially blocks the lower end portion of the pocket. The support is movable from each of the closed positions to an open position in which sheet material is movable out of the pocket through the lower end portion of the pocket. The pocket includes a rack and a pinion which are relatively movable to move the support between each of the closed positions and the open position.
Abstract:
Height barriers (15a, 15b) on the bottom of the feed arm frame (5) are located a distance above the bottom of paper drawer (1) of a printer (13). the drawer is pulled out to load paper, and then pushed in. If the paper stack (25) is high enough to encounter the barriers, paper which encounters the barrier is pushed off the top of the stack as the drawer moves further. The pushed paper emerges in front of the printer and is removed by the operator. Back restraint (17) is integral to the elevated region (17b) followed by an inclined region (17a). Overloading of paper is prevented and the paper stack not uncompressed during subsequent paper feed.
