摘要:
The sheet stacker includes a sheet conveyor arrangement, configured for feeding a plurality of sheets and having a sheet discharge end, and a stacking bay. In the stacking bay sheets delivered by the sheet conveyor arrangement are formed into stacks. A stack conveyor is provided in the stacking bay and is movable in a conveyor direction parallel to a sheet feeding direction, according to which the sheets are fed from the sheet discharge end onto the stack conveyor. The sheet discharge end is configured and controlled such that it is gradually lifted during sheet stacking, in order to accommodate a growing stack of sheets being formed on the stack conveyor. A stop plate is positioned in the stacking bay above the stack conveyor and in front of the sheet discharge end of the sheet conveyor arrangement. The stop plate is configured and controlled to be gradually lifted from the stack conveyor as the sheet stack grows, to be withdrawn upon completion of the stack thus allowing removal of the stack in an evacuation direction substantially parallel to the conveyor direction, and to be lowered towards the stack conveyor again.

A Stacking Apparatus is proposed that performs the purpose of receiving the boxes being produced by a Rotary Die Cutter and transporting the boxes through the apparatus such that stacks of the boxes are created and exit from the discharge end of the apparatus. It embodies the four functional modules, Layboy Function, Shingling Function, Stacking Function and Hopper Function. These four functions are embodied such that it has the advantages of a fixed position Hopper Function and still provides Die Board Access, Running Layboy Roll Out and Sample Sheets.

One embodiment of the present disclosure relates to a stacking device including a conveyor belt configured to move one or more items towards a receiving storage hopper configured to receive the one or more items from the conveyor belt. The one or more items may form a stack of items in the receiving storage hopper. The stacking device may further include a sensing device configured to determine a level of the stack of items in the receiving storage hopper. The stacking device may be configured to adjust a height of the conveyor belt relative to the storage hopper based on the level of the stack of items in the receiving storage hopper.

User labor relating to determining on an alignment condition is reduced and a stable conveying operation is realized by aligning a sheet bundle also when a sheet bundle is added. A sheet bundle composed of multiple sheet materials is placed on a loading platform. An encoder pulse unit detects the amount of the sheet bundle placed on the loading platform based on the opening amount of a pressure plate. A control unit determines on an alignment condition according to the amount of the sheet bundle. Rotating members align the sheet bundle in accordance with the alignment condition. When it is determined that another sheet bundle has been added to the loading platform, the control unit updates the alignment condition according to the total amount of the other sheet bundle and the sheet bundle remaining on the loading platform.

A system and method are provided improving stack integrity for a set of image receiving media substrates at an output of a compiler in an image forming device by supplementing a compiler shelf with a pair of augers having a unique planar lead-in for a top surface of the augers. The vertical compiler components reduce a “stepped” configuration of conventional compiler systems to keep a bottom sheet substantially “flat” thereby reducing a tendency for the bottom sheet to disadvantageously shift during in-set alignment processing. The large flat surface at the top of the augers effectively extends the plane of the lead edge shelf. A larger contact area with the sheets/sets of image receiving media substrates, along with the flatter shape of the sets, results in a more stable stack with a lesser tendency of individual sheets to migrate away from a registration edge.

A paper board stacking mechanism includes a transfer platform, a front conveyor group, a rear conveyor group, an inclination device, an elevation platform, and a stop plate. The transfer platform receives and conveys cut paper boards rearward. The front conveyor group includes first and second belt conveyors. The first belt conveyor is connected to the transfer platform. The second belt conveyor is connected to the rear end of the first belt conveyor. The rear conveyor group includes third and fourth belt conveyors. The paper boards pass through the front conveyor group and the rear conveyor group to then form at least a paper board stack. The rear end of the fourth belt conveyor maintains a fixed height difference from a surface of the elevation platform on which no paper board stack is loaded or from a top end of a paper board stack positioned on the elevation platform.

A device for stacking sheets includes a layboy, a transfer conveyor, a main conveyor, a diverting apparatus, and an accumulator. The main conveyor is pivotably mounted to a base to that it may be pivoted between an upper position and a lower position. The diverting apparatus has a plurality of diverting slats pivotably mounted to a support shaft so that the slats may be raised and lowered. When the main conveyor is in the upper position, the diverting slats are not activated, that is, they are not raised. Accordingly, when sheets are transferred along and discharged from the main conveyor, the trajectory of the sheets is basically the same as the angle of the conveyor. In contrast, when the main conveyor is in a lower position, the slats are raised. Accordingly, discharged sheets are diverted so that the trajectory of the sheets is different than the angle of the conveyor. The slats may be placed at any chosen angle. By adjusting the angle of discharge of sheets with respect to the main conveyor, interlock jamming is minimized in the accumulator. The sheet stacking device, including the diverting apparatus, is controlled by a programmable logic controller interfaced with a touch screen.

A device for stacking flat, flexible postal items in a stacking compartment in an upright position includes a stacking roller positionable in proximity of the stacking compartment. A covered belt system feeds the postal items consecutively to the stacking roller, wherein the belt system has a first belt and a second belt. A deflection roller on an axis deflects the first belt from the second belt so that the second belt continuous to transport a postal item to the stacking roller. A first profile roller on the deflection roller has a predetermined roller length and includes a number of diameter taperings over its roller length. Deflectable pressure means press the postal items into the diameter taperings of the first profile roller to reduce a free flexible lengths of a postal items.
