A label grabbing method and a grabbing mechanism are disclosed. The label grabbing method comprises: step S1, a conveying assembly (20) driving a plurality of labels (10) to move simultaneously so as to move the plurality of labels (10) to a position for grabbing; and step S2, a pickup assembly (30) picking up at least two labels (10) at the position for grabbing. The label grabbing method solves the problem in the prior art of a label grabbing method having too large a grabbing equipment loss.

The object of the present invention is to propose a novel device and a novel method to allow the transportation of printable substrates precisely, suited to substrates of various types, sizes and thicknesses. Furthermore, the invention is suited to printing machines that involve no contact with the substrate, such as inkjet printing machines.

A transport device includes a transport unit that transports a sheet-like transport material without holding a one-end-side portion of the transport material in a transport direction; and a blowing unit that blows air against a lower surface of the transport material that is transported by the transport unit via multiple blowing holes that open with respect to the lower surface, an arrangement interval of the multiple blowing holes in a direction of intersection with respect to the transport direction being smaller at two end portions than at a central portion of the blowing unit.

A heating device includes a heating unit that heats in a non-contact manner an upper surface of a transport material that is transported, and a blowing unit that blows air against a lower surface of the transport material via a blowing hole that is provided in an opposing surface opposing the lower surface of the transport material, the opposing surface being obliquely disposed with respect to a horizontal direction.

A main mover and sub mover are made to run while changing a relative distance of the sub mover with respect to the main mover to change contact positions of cams and cam followers based on a holding position of a sheet member detected by a position detection device to thereby change a position in a horizontal plane of a holder and correct a holding position of the sheet member held at the holder to a preset reference position.

A system (10) includes an intermediate transfer member (ITM) (44) and a substrate conveyor (80). The ITM (44) is configured to receive droplets of one or more printing fluids so as to form an image thereon, and to transfer the image to a target substrate (50). The substrate conveyor (80) is configured to grip and move the target substrate (50) to and from the ITM (44) for transferal of the image, the substrate conveyor (80) includes one or more rotatable elements (110, 200), which are configured to provide mechanical support to the target substrate (50), such that, when the target substrate (50) moves over the one or more rotatable elements (110, 200), at least one of the rotatable elements (110, 200) is configured to rotate in response to a physical contact with the target substrate (50).

In an example, a clamp may include a roller disposed on a swingarm, a slide disposed on the swingarm that may apply friction against the roller in a first position and in a second position, a cam to engage with the slide, and a latch to retain the slide in the second position. The slide may move from the first position to the second position as the slide moves along the cam, and the slide may apply a greater friction against the roller in the second position than in the first position.

An inkjet printing machine for printing individual sheets comprises at least one printing station and a transport system (100) for transporting the individual sheets through the printing 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 supported individual sheet and the support conveyor (190) are movable along the transport direction with respect to each other. The printing 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.
