An object pickup system includes an object pickup device and a calculation device. The object pickup device includes a first bracket, a suction cup installed on the first bracket and adapted to be affixed to a top surface of an object, and a distance sensor installed on the first bracket and adapted to rotate with the first bracket to scan the top surface of the object. The calculation device is operatively connected to the distance sensor. The calculation device is adapted to calculate a distance from the top surface of the object to the distance sensor and a position of an edge of an opening on the top surface of the object based on the distance data collected by the distance sensor during a scanning operation.

A machine for processing individual sheets comprises at least one processing station, in particular in inkjet printing station, and a transport system (100) for transporting the individual sheets through the processing station, along a transport direction. The transport system (100) comprises at least one gripper conveyor (150) movable along the transport direction, for gripping one of the individual sheets defining a sheet position in transport direction. The transport system (100) further comprises at least one support conveyor (190) movable along the transport direction for supporting a region of the individual sheet, wherein the support conveyor (190) comprises a vacuum system for supporting the individual sheet on an interacting surface of the support conveyor, the vacuum system comprising a plurality of orifices in the interacting surface. The machine allows for efficient and flexible handling of individual sheets, in particular large format sheets of materials such as corrugated cardboard or other materials that have a certain degree of inherent stability.

Maker machine to manufacture hygiene absorbent articles and having: a feeding line which feeds a continuous strip of impermeable material, which is intended to define a succession of sheets of impermeable material; and at least one operating unit which feeds a corresponding component of the hygiene absorbent articles to the sheets of impermeable material carried by the feeding line by way of an application device; the application device has at least one sucking pick-up head and a conveyor provided with an annular guide which is arranged in fixed position along an application path, a slide which supports the sucking pick-up head and is coupled to the guide so as to freely slide along the guide, and a linear electric motor, which has a stator that is arranged in a fixed position along the guide and a mobile slider which is electro-magnetically coupled to the stator so as to receive, from the stator a driving force and is rigidly connected to the slide.

A workpiece carrier for taking over, transporting and transferring a workpiece formed as a segment of a material web, with a support surface formed on a carrier body for placing the workpiece on, and a suction device for sucking the workpiece onto the support surface, wherein the suction device has at least one movable suction nozzle which projects from the support surface in the rest position and, when subjected to vacuum, is configured to be moved against a force holding the suction nozzle in the rest position into a retracted position in which the suction nozzle does not project beyond the support surface.

The present invention provides a denesting apparatus (100, 200), the apparatus comprising: one or more closed loop conveying tracks (130, 230), each closed loop conveying track comprising a plurality of sets of one or more de-stacking means (140, 240) movingly configured thereon through one or more de-stacking means moving mechanism (150, 250): one or more stacking magazines (120, 220), each adapted to hold a stack of sheets (110, 210) supported thereon: wherein each of the plurality of sets of de-stacking means is adapted to selectively engage an uppermost sheet from at least one of the stacking magazines in any desired order either sequentially and/or simultaneously so as to discharge the picked-up sheets onto an out-feed conveyor (180, 280) in any desired manner either one besides another or otherwise one overlapping the other.

An advancement unit (1) for causing a plurality of sheets (5) of paper, or any other material permeable to air, to move along a predetermined advancing direction (101) in a machine for paper converting, comprises a cutting group (10) which divides a web (4) made of paper, or another material permeable to air, into the sheets (5). The advancement unit (1), furthermore, provides a transfer roll (20) positioned downstream del cutting group (10), having an external surface (25) and adapted to rotate at a first predetermined angular velocity (1) about a longitudinal rotation axis (120) and to hold, alternately, on a first and on a second predetermined portion (26, 27) of the external surface (25) the head edge (5a) and the tail edge (5b) of the sheets (5) coming from the cutting group (10). A displacement group (30) is, furthermore, positioned downstream of the transfer roll (20) to move a plurality of catching members (35) along a movement trajectory (130) comprising at least one curvilinear portion (131) and at least one straight portion (132) to move the sheets (5) in a partly overlapped configuration along a predetermined advancement trajectory (135).
