The invention pertains to the field of industrial machinery for converting paper and/or for processing strip materials, and relates to a paper mill rewinder for forming reels of paper strip material, in particular, but not exclusively, tissue paper, of conventional or structured type, non-woven, TAD (Through Air Drying), or other similar materials characterized by having a very light weight and low density, with continuous, or non-stop, reel change device. Said rewinder (1) comprises: a supporting frame (3); feed means (4) for a winding rod (A); a main forming cradle (C1) for a reel (B) around said winding rod (A), comprising a first (5) and a second (6) winding roller; means for unloading (7) said reel (B) once formed; a control unit, a secondary pre-forming cradle (C2) for said reel (B), comprising a third winder roller (8) and lateral supporting means for said reel (B); means for transferring said reel (B) from said secondary pre-forming cradle (C2) to said main forming cradle (C1), where said transfer takes place without interruption to the winding, of the strip (N) onto said rod (A).

The present application relates to a tab roll replacing device and a winding apparatus. The tab roll replacing device includes an unwinding mechanism; a roll mechanism, including a transfer plate, a first floating clamping assembly, a second floating clamping assembly, and a first fixed clamping assembly; a cutting mechanism for cutting off a tab material strip clamped by the first floating clamping assembly and the first fixed clamping assembly, or the second floating clamping assembly and the first fixed clamping assembly; and a strip splicing mechanism for connecting the tab material strip output by the unwinding mechanism.

A stamping strip reel replacing system includes an autonomous mobile robot and an automatic guide vehicle. The autonomous mobile robot is adapted to autonomously move to a position where a reel driving shaft for mounting the reel is located, and includes a grabbing tool for grabbing the reel. The automatic guide vehicle moves together with the autonomous mobile robot, and carries an empty reel wound with no stamping strip. The autonomous mobile robot is further adapted to unload a full reel wound with the stamping strip from the reel driving shaft and place the unloaded full reel onto the automatic guide vehicle by operating the grabbing tool. The autonomous mobile robot is further adapted to grab the empty reel from the automatic guide vehicle and mount the grabbed empty reel onto the reel driving shaft by operating the grabbing tool.

In some examples, an access point that leads into a safety zone of a roll unwinder or winder is monitored by a monitoring sensor system. The monitoring sensor system includes two scanners having respective measuring beams that pass over an angular region situated in the same plane extending in an opening. The access point is monitored in a pattern of multiple protection fields having various sizes and/or shapes. Multiple ones of the protection fields are encompassed by a next-larger and/or next-wider protection field, entirely or at least viewed in the width and toward the top. The scan images of the two scanners are checked for a breach of the relevant protection fields in differing, adjoining, or overlapping partial regions of the plane. Information about the permissibility of a determined protection field breach is derived by evaluation of breach patterns of breached protection fields obtained in the two partial regions.

The invention relates to a method and a system for moving and labelling reels (R.sub.1, R.sub.2, R.sub.3, R.sub.4, . . . R.sub.n) of a web material such as paper or nonwoven in which each reel has a central core piece (3) which is hollow and around which the web material is wound. A robot arm (6) is inserted into the central core piece (3) of at least one reel (R.sub.1) and is then used to move the (R.sub.1) from a first position (P1) to a second position (P2) and to fix an inner label (15) onto the central core piece (3). According to the invention, the inner label (15) is placed on the robot arm (6) before the robot arm (6) is inserted into the central core piece (3) and the robot arm (6) is used both to fix the inner label (15) to the central core piece (3) and to move the at least one reel (R.sub.1).

A processing line processes logs of convolutely wound web material and has upstream and downstream sections. A main accumulator has buckets that receive, hold, and release logs. An input feeder receives logs from the upstream section and conveys them to a bucket of main accumulator. A loader has a loader accumulator and loader buckets that receive, hold, and release logs. A transfer conveyor between the main accumulator and the loader receives a log from the main accumulator bucket and conveys the log a loader bucket independently of the input feeder. The loader receives a log from the transfer conveyor. The loader conveys the log in the loader bucket to a discharge of the loader. The loader discharge discharges the log from the loader bucket to the downstream section of the processing line.
