A sheet processing apparatus includes a controller configured to control operations of the pair of aligning members such that a sheet bundle disposed on a first stacking portion is aligned by the pair of aligning members of the pair of aligning members at a position shifted to a side of one aligning member in a width direction perpendicular to the discharge direction of a sheet with respect to a sheet discharge range in which a sheet is discharged at the time of discharging the sheet from a discharge portion, and, before the aligned sheet bundle is discharged to a second stacking portion by a bundle discharge portion, the other aligning member of the pair of aligning members is moved to the outside of the sheet discharge range in the width direction.

The disclosure relates to a method for producing a stack formed from multiple electrochemical cells, each of the electrochemical cells having a plurality of constituent components including at least one membrane component and a bipolar plate. The method includes orienting each constituent component of the constituent components on an edge of the constituent component, forming aligned components by feeding each constituent component of the constituent components oriented on the edge of the constituent component to a shaking boom, and forming the stack from the aligned components. The disclosure furthermore relates to a device for producing such a stack.

A sheet processing device in an embodiment includes a conveyance path, a stacker, a post processing section, and vertical alignment members. The conveyance path conveys sheets in a conveying direction and stacks the sheets. The stacker restricts a leading end of the conveyed sheets. The stacker is movable in the conveying direction. The post processing section processes the sheets further on an upstream side in the conveying direction than a position where the sheets are supported by the stacker. The vertical alignment members feed the sheets in the conveying direction toward the stacker. The vertical alignment members are enabled to come into contact with a bundle of the sheets supported by the stacker. The vertical alignment members are movable in the conveying direction integrally with the stacker.

An electrode stacking apparatus provided with a planar motor device (B) comprised of a flat plate-shaped stator (50) and a plurality of movers (40) able to move on a flat surface (51) of the stator in any direction along the flat surface (51) and able to rotate about a perpendicular axis of the flat surface (51) in a state magnetically floating from the flat surface (51). When stacking a new sheet-shaped electrode (1) held by an electrode conveyor device (A) arranged above the planar motor device (B) on a stacked electrode holder (60) of a mover (40), the mover (40) is made to move in synchronization with movement of the new sheet-shaped electrode (1) so that the new sheet-shaped electrode (1) continues to face the sheet-shaped electrode stacking position on the stacked electrode holder (60).

A stacker includes a placement part that stacks thereon sheets discharged from a discharge port by a conveyor that conveys the sheets; a side guide that regulates edges of the sheets in a width direction intersecting a discharge direction of the sheets; a guide driver that moves the side guide along the width direction; and a controller configured to control the guide driver to position the side guide at a position where the sheet discharged from the discharge port is supported from below by the side guide.
