A loading unit includes a processing tray, alignment units, and a paddle. In the processing tray, a medium is placed. The alignment units are disposed an interval in a Y direction to align a downstream tip end in a positive A direction of the medium. The paddle moves the medium that has been fed onto the processing tray toward the alignment units. A coefficient of friction of a contact surface of the alignment unit is higher than a coefficient of friction of a front face of the alignment unit, and the contact surface is positioned downstream of the front face in the positive A direction.

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 method moves a stack of products by a robot. The robot has an articulated arm and at least one gripper disposed on the articulated arm to grip the stack of printed products and the stack of products selectively being turned. The method includes pivoting the stack of products through an effective angle α1< >180° and subsequently pivoting the stack through an effective angle α2=180°−α1 or pivoting the stack back through an effective angle α2=−α1. This method of moving stacks of products is performed in an automated way and in particular of depositing them in a turned or unturned arrangement.

A medium transport device includes a lower guide member, a processing tray, a feeding section, and a notch. The lower guide member supports a medium transported and guides the medium toward the processing tray. The processing tray includes an alignment member, and a plurality of media are stacked in the processing tray. The feeding section includes a paddle member having a rotation center between the processing tray and the lower guide member such that a rotation locus of a distal end intersects the lower guide member, and the feeding section is configured to feed the medium toward the alignment member. The lower guide member has a notch, and an upstream end of the notch in the transport direction is formed at a position inside the rotation locus in the lower guide member.

An apparatus for separating battery plates includes a work surface for receiving a stack of battery plates, and an alignment mechanism for aligning the battery plates on the work surface. The work surface is movable between a first position in which it is angled with respect to a horizontal plane and a second position in which it is substantially aligned with the horizontal plane. When the work surface moves between the first and second position adjacent battery plates of the stack are displaced relative to each other.

A sheet post-processing apparatus including a binding mechanism, a tray, a shift mechanism, and a control unit is provided. The binding mechanism is configured to apply binding to a sheet. The sheet applied with the binding is stacked on the tray. The shift mechanism is configured to perform a shift operation in which a side surface of the sheet is pushed and the sheet is deviated in a sheet width direction orthogonal to a discharge direction during discharge of the sheet to the tray. The control unit is configured to cause the shift operation to be performed by dividing the number of times for the shift operation into a plurality of times.

Example implementations relate to media stacking mechanisms. In some examples, a printing device can include a stacking mechanism that includes a tamper to tamp print media positioned within the stacking mechanism, and a controller comprising instructions to: tamp a first sheet of print media received at the stacking mechanism a first distance based on a first size of the first sheet of print media, tamp a second sheet of print media received at the stacking mechanism a second distance based on the second size of the second sheet of print media, wherein the second sheet of print media is positioned over the first sheet of print media, and tamp a third sheet of print media received at the stacking mechanism the second distance when the third sheet of print media is the first size, wherein the third sheet of print media is positioned over the second sheet of print media.
