A gripper arrangement for lifting a flexible semi-finished product from a support, wherein the gripper arrangement comprises a flexible semi-finished product resting on a support and at least one pair of grippers with a suction gripper or needle gripper and with at least one clamping gripper, wherein the suction or needle gripper is pivotable around an axis between a pick-up position for picking up an edge of the flexible semi-finished product and a transfer position for transferring the edge of the flexible semi-finished product to the clamping gripper. Furthermore, a corresponding method is described.

An automatic bag loading system includes a transfer arm configured to grab a bag and transfer the bag from a conveyor a bag gripper, which then rotates the bag to a filling station. The system further includes a detection device to detect a location of a leading edge of the bag between the conveyor and the bag gripper.

The present invention relates to a side paper feeding apparatus for feeding raw side paper for paper cup manufacturing, the side paper feeding apparatus comprising: a shuttle cam which is rotated by interlocking with a drive shaft and which horizontally reciprocates a shuttle plate which transfers raw side paper disposed on an upper part to a paper cup former; a driving cam unit provided under the shuttle cam and provided with a rotary cam formed on a rotary shaft fixedly coupled to the shuttle cam to intermittently rotate a first turret, an oscillator cam formed on the rotary shaft to oscillate a second turret, and link arms, wherein one end of each link arm is coupled to one end of a first shaft of the first turret and one end of a second shaft of the second turret, and the other ends are rotatably coupled; and a side paper transfer arm unit including an arm plate coupled to the other end of the first turret, rotational arms each having one end rotatably coupled to the outer circumferential surface of the arm plate at equal intervals, sub arms fixedly coupled to the other ends of the rotational arms in a direction perpendicular to the rotational arms, respectively, and having pads sucking and releasing the raw side paper by vacuum suction, and a track cam coupled to the other end of the first shaft of the first turret, and reciprocating the sub arms in the outer circumferential direction of the arm plate at least in a section in which the pads suck the raw side paper from a magazine and a section in which the raw side paper is released from the upper part of the shuttle plate.

The present invention relates to a method of stacking individual sheets and a stacking machine for handling individual sheets, the stacking machine comprising a frame assembly (13) including support columns (711, 811) for supporting the delivery station (70), the transfer station (80) and the elevation station (82). The delivery station has a delivery table and the transfer station including a handling arm (85) is movable from a first position above the delivery table to a second position above the elevation station. The handling arm includes a holding member (86) for contacting the sheets individually and transferring the sheets individually from the delivery table to the elevation station and releasing the sheets individually at the elevation station. The elevation station has a platform for collecting the individual sheets and the platform is moved vertically from a first level to a second level for allowing the sheets to be stacked on top of the one another.

An automatic bag loading system includes a transfer arm configured to grab a bag and transfer the bag from a conveyor a bag gripper, which then rotates the bag to a filling station. The system further includes a detection device to detect a location of a leading edge of the bag between the conveyor and the bag gripper.

The invention relates to an insert-sheet pick-up device (13) for an insert-sheet loading device (10) of a station for receiving copy (500). The pick-up device (13) includes a suction element (20) configured to pick up an insert sheet. The pick-up device (13) includes a pivoting axis (30) and at least one telescopic arm (33) including a proximal arm (33a), one end of which is fixed to the pivoting axis (30), and a distal arm (33b), able to move with respect to the proximal arm (33a), and one end of which is pivot-articulated to the suction element (20) to move the suction element (20) between a raised position and a lowered position according to a vertical movement of the suction element (20). Also, the invention also relates to an insert-sheet loading device, a copy-receiving station and a machine for processing elements in sheet form including the insert-sheet pick-up device.

An inserter hopper device for handling a pile of inserts includes a framework, a belly plate that is connected to the framework, a carry-down cam assembly including a plurality of carry-down cams on a rotatable carry-down cam shaft having a fixed location relative to the framework and a carry-down roller assembly including a plurality of carry-down rollers on a rotatable carry-down roller shaft having a movable location relative to the framework. The carry-down rollers are opposed to and spaced from the carry-down cams, providing a nip having a nip distance therebetween. At least one biasing element biases the carry-down roller shaft toward the nip. The inserts are moved through the nip individually. A thickness tuning adjustment assembly moves the carry-down roller assembly to adjust the nip distance. A vacuum assembly is in communication with a movable sucker assembly that has sucker ports being movable toward and away from the nip.

A gripper arrangement for lifting a flexible semi-finished product from a support, wherein the gripper arrangement comprises a flexible semi-finished product resting on a support and at least one pair of grippers with a suction gripper or needle gripper and with at least one clamping gripper, wherein the suction or needle gripper is pivotable around an axis between a pick-up position for picking up an edge of the flexible semi-finished product and a transfer position for transferring the edge of the flexible semi-finished product to the clamping gripper. Furthermore, a corresponding method is described.
