This application discloses a rewinding apparatus and a rewinding method. The rewinding apparatus is configured to rewind a strip. The rewinding apparatus includes a rewinding mechanism and a switching mechanism. The rewinding mechanism includes two shafts that are opposite to each other along a first direction and spaced out. The two shafts are configured to rewind the strip along different conveyance paths separately. The switching mechanism includes a moving roller. The moving roller is configured to drive the strip to switch from one shaft to another shaft so that the strip switches from one conveyance path to another conveyance path. The rewinding apparatus and rewinding method disclosed in this application achieve high space efficiency and high switching efficiency.

The present disclosure relates to an automatic roll-replacing apparatus, including: an unwinding device, a starting-end-handling device comprising a support mechanism and a pick-up mechanism, the support mechanism is located between the standby material roll and the working material roll; the pick-up mechanism is configured to pick up a material strip starting end of a standby material strip and pull the material strip starting end to reach a location between the support mechanism and the working material roll; and a strip-connecting device including two strip-connecting mechanisms that either carries a tape.

A film-roll supply device improves replacement of a film roll in a bag-making and packaging machine. A film roll replacement device supplies a first film roll to a bag-making and packaging machine. The film roll replacement device is provided with a holding section and a first driving unit. The holding section receives the first film roll to be supplied to the bag-making and packaging machine. The first driving unit changes an orientation of the holding section between a first orientation used when receiving the first film roll and a second orientation used when supplying the first film roll to the bag-making and packaging machine.

Winder for an endless lane of a plastic web (2), with a revolving unit (6, 6, 55, 90), which is constructed so as to be rotatable about its axis (16) and has at least two winding shafts (10 to 12, 10 to 12) running parallel to its axis, onto which winding cores (17) can be loaded, then wound with the web (2) to a roll (18), finally unloaded therefrom again as finished rolls (18), wherein on both sides of the revolving unit (6, 6, 50, 90) support arrangements are arranged, in which the winding shafts (10 to 12, 10 to 12) are supported at their corresponding ends therein, and wherein the support for one end of the winding shafts (10 to 12, 10 to 12) is constructed so as to be detachable, such that the respective winding shaft (10 to 12, 10 to 12), with released support, can be loaded and unloaded from this end, characterized in that the detachably constructed support arrangements each have a gripper arrangement (36 to 38) with a two-armed scissor unit (39 to 41), the scissor arms (42, 43) of which surround the winding shaft (10 to 12, 10 to 12) in the closed position and are pivoted away therefrom in the open position.

Systems and methods for connecting the films of a first roll and a second roll in a packaging machine. The system includes a cutting device to cut the film of a first roll at a cutting position upstream side of a holding position with respect to a feeding direction toward a former while the film is held by a holding device. The system also includes a robot to move the second roll to a connecting position where a leading end of second roll film overlaps with a film terminal end of the first roll film. The system further includes a connecting device to connect the film leading end of the second roll film to the film terminal end of the first roll film. The robot to move the second roll from the connecting position to a set position after connecting the films, so that the second roll film is tensioned.

The invention relates to a mobile robot, to a supply system, and to a method for changing label rolls on a labeling assembly for labeling containers. The mobile robot accordingly comprises a vehicle unit for changing locations of the robot and a manipulator unit with a multi-axle manipulator and an associated end effector for manipulating label rolls. Because the end effector is designed to grip the outer circumference of the label rolls and emptied roll cores of label rolls so as to carry them, ergonomically problematic work steps when introducing label rolls can be accomplished exclusively by machine with a high degree of precision and in a material-saving manner.
