A gripper is for holding and depositing a stack of sheet material at a depositing location, and has at least one first gripping element, which comprises or forms a first contact surface for contact with the stack, and at least one second gripping element, which includes a second contact surface for contact with the stack. The first and second contact surfaces are designed for contact with the stack on both sides. The gripping elements are guided adjustably with respect to one another so that the contact surfaces can be moved with respect to one another in the direction of the surface normals that are respectively associated with the contact surfaces to hold the stack between the contact surfaces. The first gripping element is mounted to pivot about a pivot axis so it can pivot between a gripping position, and a release position.

The invention relates to a packaging system (1) and to a method for using the same. The packaging system (1) comprises a packaging module (2), a first transport device (3) for feeding articles to the packaging module (2) in a first transport direction (TR1), and a second transport device (4) for feeding flat packaging materials (20) arranged in a first upright orientation (22sv1) in a second transport direction (TR2). The packaging system (1) comprises a handling device (5) for arranging the flat packaging materials (20) on the second transport device (4), and at least one displacement unit (8), configured to displace a plurality of upright packaging materials (20) relative to one another. The displacement unit (8) has vertically oriented side walls (9) and a support surface (10), wherein an angle differing from 90 degrees is formed between each of the side walls (9) and the support surface (10).

A marking device includes a marker conveyor, a memory, and circuitry. The marker conveyor conveys a marker in a first direction from a start timing to an end timing and places the marker on an uppermost sheet of each sheet bundles each having a predetermined number of sheets conveyed in a second direction orthogonal to the first direction and stacked on a stacking table in a third direction orthogonal to the first direction and the second direction. Each of the sheets has a width in the first direction and a length in the second direction. The memory stores the width. The circuitry acquires the width from the memory and controls the marker conveyor to delay or advance the end timing according to the width acquired from the memory.

The present invention relates to a handling installation for handling sheets of cardboard or similar material applicable for implementation thereof in an automated production facility, comprising a first receiving station (1) configured to receive packages formed by cardboard sheets, each of the sheets being defined by four sides, and a second distribution station (2) in which the sheets are delivered face-down coming from the receiving station by means of sheet handling means. The first and second stations comprise modules that are independent from each other, the handling means comprising a robot arm provided with a head with clamping means to hold the package of sheets on any of the four sides, the head having a hinge point that can be coupled to a robot arm, capable of conveniently moving and orienting the clamping means in any of the coordinate axes, the robot arm being mounted on a base that is independent with respect to the first and second stations.

A sheet processing device includes a rotator, a first nipper, a conveyor, a second nipper, a detector, a memory, and circuitry. The rotator winds a two-ply sheet around the rotator to generate a winding circumferential difference between two sheets of the two-ply sheet to separate the two sheets. The detector detects an abnormal condition, in which a gap greater than a given interval is not formed between the two sheets around the rotator. The memory stores a detection result as the abnormal condition. The circuitry is to increase a nipping force of the second nipper with the rotator, and increase the nipping force in a present sheet processing to be greater than a previous nipping force of the second nipper in a previous sheet processing, when the memory stores the detection of the abnormal condition in the previous sheet processing, to wind the two sheets around the rotator.

A scanner includes a reading unit that reads an image of a paper, a medium feeding portion that is capable of selecting a first feeding mode in which a separation feeding for separately feeding a paper bundle in which a plurality of sheets of paper is overlapped with each other is performed and a second feeding mode in which a non-separation feeding for collectively feeding the paper bundle without separating is performed, and a pair of first transporting rollers and a pair of second transporting rollers that transport the paper fed by the medium feeding portion, in a case in which the medium feeding portion feeds the paper in the second feeding mode, a first driven roller and a second driven roller respectively constituting the pair of first transporting rollers and the pair of second transporting rollers are driven in a rotation direction where the paper is transported.
