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.

Features for systems and methods for loading items into a tray are disclosed. The system may have an item conveyor configured to move the items towards a tray conveyor. The tray conveyor may be configured to move trays to receive items from the item conveyor into the tray. One or more sensors may detect the height of the items on the item conveyor and/or in the tray, and/or the position of the trays on the tray conveyor. A controller may receive data related to the one or more detected heights of the items and/or the position of the trays on the tray conveyor and correspondingly control movement of the item and/or tray conveyors for efficient loading of items into the tray and efficient movement of the trays for further processing. Tray conveyor movement sensors may detect movement of the trays or tray conveyors for further control or reliability of the system.

A lifting apparatus includes a motor, circular support members, power transmission members, guide mechanisms, and electromagnets. The circular support members provide tensile forces to wires connected to a load. The power transmission members rotate around the rotation axis Ax as a center of rotation by driving force of the motor. The guide mechanisms support the circular support members so as to enable the circular support members to slide in a predetermined ranges along a radial direction of the rotation axis, respectively. The electromagnets forcibly arrange the circular support members using electromagnetic force at a position that the center axes of the circular support members agree with the rotation axis in the predetermined ranges.

Personnel saving of a process from a printer to a sheet processing machine is achieved. A general printing management device is connected to be communicable with a conveyance management device that manages a plurality of automatic guided vehicles each conveying a stacker in which paper ejected from a printer is stackable. The general printing management device generates conveyance instruction information for conveying a stacker in which paper ejected from the printer is stacked from a sheet receiving position of the printer to a sheet supply position of a next processing machine, based on job information in which a manufacturing process procedure for manufacturing a printed product is registered, and transmits the conveyance instruction information to the conveyance management device.

Provided is a stacker including a stacking shelf on which printed paper from a printer is received and stacked, a lifting and lowering mechanism that lifts and lowers the stacking shelf, and a stacker control unit that controls the lifting and lowering mechanism. The stacker control unit controls the lifting and lowering mechanism to lift and lower the stacking shelf to a first predetermined height corresponding to the printer at a receiving position for receiving the paper from the printer, and to lift and lower the stacking shelf to a second predetermined height corresponding to a sheet processing machine at a paper supply position for supplying paper to the sheet processing machine, the paper supply position being different from the receiving position.

Apparatus for applying noise reducing elements to tyres for vehicle wheels. The apparatus includes a loading station of stacks of noise reducing elements, an extraction station of noise reducing elements from each stack placed downstream of the loading station, and a conveyor placed downstream of the extraction station and extending along a predefined path. The conveyor is configured for supporting and advancing in a row the noise reducing elements extracted from the stacks which are then applied to a radially inner surface of the tyres. The extraction of each of the noise reducing elements contemplates: retaining a first noise reducing element placed at the base of a stack; raising the remaining noise reducing elements of the stack from the first noise reducing element; moving away the first noise reducing element according to a set path; and lowering the remaining noise reducing elements of the stack.

Provided is a pile preparation unit for changing a pallet support of a pile of sheets with a first end and a second end where the pallet has a support side supporting the pile of sheets at the first end. The pile preparation unit may include a rotation unit configured with an infeed opening for receiving a pallet with a pile of sheets, the rotation unit configured with a rotating structure to rotate a lift unit about a rotational axis. The lift unit is configured with a lift structure fixed to the rotating structure and has a lift plate movable along the lift structure to engage with the second end of the pile of sheets and to move and position the pile of sheets transverse, relative to the rotational axis, providing a portal for changing a pallet.

A sheet conveying device includes an auxiliary tray, a sheet feeding tray, a roller, a driving mechanism, and a pickup roller. The sheet feeding tray is adjacent to the auxiliary tray on a lateral side of the auxiliary tray. The roller is configured to move in a thickness direction of a sheet bundle placed on the auxiliary tray to contact an end of the sheet bundle facing the sheet feeding tray. The driving mechanism is configured to laterally move the auxiliary tray to be on top of the sheet feeding tray when the sheet bundle placed on the auxiliary tray is transferred to the sheet feeding tray. The pickup roller is configured to pick up a sheet one by one from the sheet bundle transferred to the sheet feeding tray.
