Gripper assembly, apparatus for recovering a layout from a sheet material and method for separating a layout from waste of a sheet material
A gripper assembly for recovering a layout (22) from a sheet material (12) is presented. It comprises a vacuum gripper (26) with a gripper body (32) on which an array of air flow openings (34a, 34b) is arranged. Air flow openings (34a) associated with one or more blanks (20) of the layout (22) are selectively open and air flow openings (34b) associated to waste (28) of the sheet material (12) are selectively closed. Additionally, an apparatus for recovering a layout (22) from a sheet material (12) comprising such a gripper assembly is described. Furthermore, a method for separating a layout (22) from waste (28) of a sheet material (12) is explained.
Vacuum within a pallet conveyor for a printing system
In one example, a pallet conveyor for a printing system is described, having a track, a pallet to support a print substrate and move on the track, and a vacuum mechanism to selectively apply a vacuum at the pallet. A boundary of the vacuum applied at the pallet is synchronized with an edge of the print substrate.
SHEET-FED PRINTING PRESS
A sheet-fed press includes at least two units embodied as modules. At least two of the modules respectively comprise at least one individual drive which is used to transport a sheet through the respective module or through at least one active region of the respective module. At least one of the at least two modules is configured as a non-impact cover module. At least one component of the at least second module comprises at least one drying system or one drying device. The sheet-fed press includes a transport path for transporting the sheets. At least the section of the transport path provided for the sheets, and secured by the non-impact cover module, extends at least essentially flat or essentially horizontally.
MEDIUM TRANSPORTING APPARATUS AND POST-PROCESSING APPARATUS
A medium transporting apparatus includes a transport belt that has a loop shaped, an clinging mechanism that causes a medium to cling to the transport belt, a rotation mechanism that rotates the transport belt in a first and second rotation direction, and an intermediate stacker on which the medium transported by the transport belt is stacked, in which the clinging mechanism cling an upper surface that is opposite to a lower surface of the medium on the intermediate stacker side, and after rotating the transport belt, to which the medium is cling, in the first rotation direction to transport the medium in a first transport direction, the rotation mechanism rotates the transport belt in the second rotation direction to transport the medium in a second transport direction that is opposite to the first transport direction so as to stack the medium on the intermediate stacker.
MEDIUM TRANSPORT APPARATUS AND POSTPROCESSING APPARATUS
A transport mechanism includes a transport belt in which holes are formed and a suction clinging mechanism. The transport mechanism transports the medium in the first transporting direction, and when the upstream edge reaches a switching position, the transport mechanism transports the medium in the second transporting direction and stacks the medium in a stacker. The suction clinging mechanism includes an opening of a first suction chamber and an opening of a second suction chamber, and the opening of the first suction chamber is located downstream of the opening of the second suction chamber in the first transporting direction. The switching position is located upstream of the opening of the first suction chamber in the first transporting direction. In the first transporting direction, the distance from the switching position to the opening of the first suction chamber is longer than the length of each hole.
MEDIUM TRANSPORTING APPARATUS AND POST-PROCESSING APPARATUS
A medium transporting apparatus includes a transport belt that has a loop shaped, a cling mechanism that causes the medium to cling to the transport belt, a rotation mechanism that transports the medium by rotating the transport belt, a plurality of detection units that detect an transport direction end of the medium, a controller that corrects a skew of the medium, and a stacker on which the medium transported by the transport belt is stacked, in which the plurality of detection units are arranged at positions that are on an upstream side of the transport belt in the first transport direction and that are different from each other in a width direction, and the controller corrects, according to a result of the detection by the detection units, the skew of the medium in a state of being cling to the transport belt.
MEDIUM PROCESSING APPARATUS, POST-PROCESSING APPARATUS, AND MEDIUM TRANSPORTING APPARATUS
A suction mechanism for suctioning a loop transporting belt a medium processed by a processing unit, a rotation mechanism for rotating the transporting belt, a stacker for stacking the medium transported by the transporting belt, and a change mechanism for changing a movable area are included. The rotation mechanism, after suctioning the medium to the transporting belt to rotate in a first rotation direction to transport the medium in a first transport direction, rotates the transporting belt in a second rotation direction to transport the medium in a second transport direction to stack the medium on a stacker. The change mechanism narrows a movable area when the medium is transported in the second transport direction compared to an area when the medium is transported in the first transport direction.
SHEET-FED PRESS
A sheet-fed press includes at least two units embodied as modules. The at least two modules respectively each comprise at least one individual drive, each individual drive being configured as a position-controlled electric motor. At least one of the at least two modules is configured as a non-impact coating module, and the at least coating module is arranged as at least another of at least two modules that is configured as a primer module or as a painting module.
SHEET CONVEYING SYSTEM
A sheet conveying system comprising a first conveyor and a second conveyor arranged downstream of the first conveyor in a transport direction for taking-over a sheet from the first conveyor, the first conveyor having a belt that is driven to move over a stationary attraction mechanism, the attraction mechanism being arranged to exert, onto a sheet conveyed on the first conveyor, an attraction force that is proportional to an area of coverage of the sheet on the attraction mechanism, characterized in that the attraction mechanism is arranged to attract the sheet with a larger force per area in a downstream zone of the first conveyor than in an upstream zone thereof.
SHEET CONVEYING DEVICE AND IMAGE FORMING DEVICE
A sheet conveying device includes a first conveyer and a second conveyer, each including a upstream-side pulley and a downstream-side pulley with respect to a conveying direction, an endless belt stretched around these pulleys, and a suction mechanism provided on an inner periphery relative to a conveying surface of the endless belt, along the conveying direction, wherein a third conveyer including a upstream-side pulley and a downstream-side pulley relative to the conveying direction and an endless belt stretched around these pulleys is provided between the first conveyer and the second conveyer, and in a state where the third conveyer is viewed from a side of the conveying surface, the upstream-side pulley of the third conveyer is arranged to be overlapped with the downstream-side pulley of the first conveyer, and the downstream-side pulley of the third conveyer is arranged to be overlapped with the upstream-side pulley of the second conveyer.
