A depalletizing machine for picking up and moving groups of articles, specifically bundles of blanks, includes a containing structure internally provided with at least one receiving area for a movable magazine containing one or more groups of articles. The machine also includes at least one access opening for allowing the magazine to be inserted into, or removed from, the receiving area. The machine also includes a collection zone configured for receiving a succession of groups of articles from the movable magazine and for moving the groups of articles towards the outside of the machine. The machine also includes at least one sensor configured for detecting a position of the movable magazine within the at least one receiving area and a pickup head configured to pick up groups of articles from the movable magazine and transferring them into the collection zone. The machine also includes a control unit configured for setting a predetermined law of motion for the pickup head as a function of at least one information item obtained from the sensor, regarding the position of the movable magazine.

A tray unit assembly includes a housing, a separating/stacking unit, a tray unit and an elevating member. The separating/stacking unit includes a separating roller unit and a stacking roller unit provided in the housing. The tray unit is provided to be inserted into the housing and includes a first tray body fixed to the housing when the tray unit is inserted into the housing, and a second tray body connected to the first tray body to be slidable in a vertical direction and having a media stacking space formed therein. The elevating member is disposed to be movable up and down and configured to be in contact with a bottom surface of the second tray body to move the second tray body toward the stacking roller unit or the separating roller unit.

The present application discloses a post-processing apparatus which performs a predetermined process after an image formation process performed by an image formation apparatus. The post-processing apparatus includes an ejection tray, which supports a sheet stack, in which sheets are stacked, and a curl prevention portion including a first tray cursor, which abuts an upper surface of the sheet stack on the ejection tray to prevent the sheet stack from curling. The curl prevention portion includes an angle changer, which changes an inclination angle of the first tray cursor with respect to the ejection tray. The angle changer sets the inclination angle to a first value when a number of sheets is a first number. The angle changer sets the inclination angle to a second value different from the first value when the number of the sheets is a second number different from the first number.

A document conveying device includes a sheet feeding tray, a sheet feeding mechanism, a discharge tray, a sheet feeding tray lifting mechanism, a top plate, a fixed wall part, and a lifting wall part. The discharge tray is provided below the sheet feeding tray. The top plate is adjacent to the sheet feeding tray on a downstream side in the sheet feeding direction. The fixed wall part is provided extending downward from an upstream side end portion of the top plate in the sheet feeding direction, and is fixed. The lifting wall part is provided extending upward from a downstream side end portion of the sheet feeding tray in the sheet feeding direction, and lifted and lowered together with the sheet feeding tray. The discharge tray includes a lowering restriction part which comes into contact with the lifting wall part to restrict a lowering of the lifting wall part.

A method for forming sheet stacks in a dispensing region of a sheet processing apparatus, involves: a) stacking sheets by a stacker wheel onto a sheet stack located on a lifting platform, b) introducing a deposition platform into the dispensing region, c) stacking further sheets by the stacker wheel onto the deposition platform arranged underneath the stacker wheel, d) introducing a gripping device into the dispensing region to take up, by the gripping device, the sheet stack formed on the lifting platform, e) removing the sheet stack formed on the lifting platform from the dispensing region, and, after the removal of the sheet stack, f) raising the lifting platform up to the deposition platform, and g) transferring the further sheet stack formed on the deposition platform onto the lifting platform and moving the deposition platform away out of the dispensing region.

A filling apparatus and to a method are for filling containers with document-of-value stacks, and to a document-of-value processing apparatus. The filling apparatus is designed for filling containers with document-of-value stacks, for example document-of-value stacks that are set down by a document-of-value processing machine in a delivery region of the document-of-value processing machine. The filling apparatus has a feed interface, a delivery interface and a transport path along which the containers can be transported from the feed interface to the delivery interface, and a filling region in which in each case one container that has been fed to the filling apparatus can be positioned in order to be filled with document-of-value stacks by means of a gripping device.
