Definitions

  • the present invention relates to improvements in paper machine winders, and more particularly winders which receive a continual supply of paper web at a high speed, wind it into a roll and automatically discharge the wound roll, provide a fresh core for starting a new roll and sever the web to release the wound roll and start the lead end of the fresh web onto the new core.
  • the features of the invention particularly relate to an improved mechanism for performing the sequence of operations necessary to cut the web in an improved manner.
  • the paper machine winder operates essentially as a'batch operation, with the winding being temporarily stopped between each wound roll to allow for cutting the web and for starting the web on a fresh core. Additionally, time must be allowed for splices, slitter setting changing, blade changes, and with the temporary shut-down necessary, the winding machine must operate at a sufficiently high speed to catch up with the output of the'papermaking machine.
  • the rule of thumb used to be that the winder should be designed for three times the paper machine speed. However, when winding rolls of smaller diameters such as 100 cm which is customary for newsprint, merely increasing the top speed of the winder is of limited value because the run times are too short between completing the roll and beginning a fresh roll.
  • a further object of the invention is to provide an improved structure for the operation of a two-drum or shaftless winder wherein the time required between rolls is reduced to increase the total output of the machine and reduce the overall operation time for winding rolls.
  • a feature of the invention is to provide for rapid automatic change-over from the complete wound roll to starting the fresh core in a manner which is reliable to the extent of starting a fresh core without losing the web, and in particular cutting the web in an improved manner.
  • the web is cut by the knife on the first drum, which is a suction drum, and simultaneously, a fresh core is brought into the nest between the drums having been prepared by adhesive on its surface, and the cut lead end of the web is immediately started onto the fresh core with the whole intermediate operation between ejection of the roll and starting of the fresh core being maintained at a minimum so as to be accomplishable in a time span of somewhere between 30 and 50 seconds.
  • the overall output of the machine is increased so that the winder can more readily keep up with the output of a high speed papermaking machine.
  • the two drum winder mechanism includes first and second drums 10 and 11 extending horizontally on parallel axes with means to drive the drums in rotation.
  • the drums define a winding nest 17 therebetween for supporting a roll being wound with the roll shown at 14 in Figure 1 as it is begun, and at 15 in Figure 1 as it is being completed.
  • a web W is led over the first or front drum 10 which is constructed as a perforated roll shell having perforations 12 therethrough.
  • the drum becomes a vacuum chamber by applying vacuum to the front side drum journal by means shown schematically at 23. The suction holds the web to the roll when the web is severed.
  • the second or back drum 11 will present a smooth supporting surface 13 to the roll 14 being wound.
  • a core carrier 16 Operating in conjunction with the winding drums is a core carrier 16 which operates to bring a fresh core into the winding nest 17 and has a roll ejector surface 21 for forcing the wound roll out of the winding nest onto roll table 32a shown in Figure 3.
  • the core carrier receives a fresh core 34 and holds the fresh core between movable jaws 19 and 20 which receive a fresh core and drop it at the appropriate time when the carrier is moved over the winding nest.
  • a knife 31 is supported on a knife carrier and arm 24 and moved upwardly between the drums from a recessed position, as shown in Figure 1, to a cutting position, as shown in Figure 3.
  • the knife has a concave curvature essentially conforming with the outer surface of the drum 10.
  • the knife extends continuously across the full width of the web and has a serrated cutting edge 32.
  • the arm for carrying the knife moves pivotally to carry the knife between the recessed position and the cutting position movable about a center 25 which is slightly eccentric from the rotational center 26 of the drum 10. This will move the knife 31 in a generally concentric path with the roll, but moving the cutting edge 32 ever increasingly closer to the surface of the web as it moves into the final cutting position of Figure 3.
  • the web W feeds under the front drum 10 up onto the surface of a roll 14 being wound.
  • the rolls 10 and 11 are driven rotationally at the surface speed of the rotation of the roll 14 being wound with control as to the tightness of winding and the tightness of the roll being obtained by applying a controlled torque differential to the rolls 10 and 11 as will be recognized by those versed in the art.
  • the carrier 16 is moved to the right as indicated schematically by the arrowed line 26 in Figure 2.
  • a fresh core 34 is placed into the carrier and the holding jaws 19 and 20 are brought together to clamp the core as shown in Figure 2.
  • An adhesive substance is applied to the outer surface of the core either by an adhesive spray means extending for the full length of the core or by means applying an adhesive tape to the core surface.
  • the adhesive on the outer surface of the core will serve to form an attachment for the lead end of the paper web when it is cut.
  • the surface 21 on the carrier engages the outer surface of the roll and the carrier, acting as an ejector, forces the roll to the right, as shown in the drawings, up over the back drum 11 onto the roll receiving table 32a.
  • the knife 31 has begun its travel, as indicated by the arrowed line 25 from its recessed position, shown in Figure 1, toward the cutting position of Figure 3. Movement of the knife is in a curved path up between the space between the drums 10 and 11.
  • Vacuum is applied to the roll 10 to hold the cut lead end of the web in place. Vacuum will be controlled by a mechanism shown at 23 schematically in Figure 1 in a manner which will be fully appreciated by those versed in the art.
  • the fresh core is brought fully over the nest 17 between the drums as illustrated in Figure 4.
  • the fresh core 34 is dropped by separating the jaws 19 and 20, and the lead end of the cut web will adhere to the adhesive surface of the core 34 upon start of rotation of drums 10 and 11.
  • the knife has moved back down to its retracted position, as indicated by the arrowed line 25 in Figure 4 to where it is in the retracted position of Figure 5 where it remains during the winding operation.
  • the carrier 16 is withdrawn to the position shown in Figure 5 in advance of the front drum 10 ready to receive a fresh core.
  • a feature of the invention is the reliable and secure cutting operation which occurs in Figure 3 in such a manner that the functions of cutting and bringing the fresh core can be performed very rapidly substantially shortening the time between the ejection of the complete roll and the starting of the roll onto the fresh core. If the cutting is not accomplished reliably and rapidly, not only will the amount of time consumed be increased, but the chance of losing the lead end of the web will be increased. If such a mishap occurs at this point, time must be allotted for the operator to pick up the lead end of the web and correct the deficiencies and this greatly slows the overall operation of the winder. Furthermore, if a mishap occurs at cutting, the starting of the lead end onto the fresh core can malfunction resulting in a bad start.
  • the present structure permits ejection of a small roll which has been the result of a bad start, as illustrated in Figure 6.
  • the carrier can be brought over in the manner indicated by the arrowed line 29 to force the bad start roll 33 out of the nest.
  • a fresh core 34 will be on the carrier to immediately start a new roll when the bad start roll 33 is ejected.
  • the ejection of the bad start roll will be accompanied by movement of the knife 31 from its retracted position as shown in Figure 1 up to its cutting position as shown in Figure 3.
  • the lead end will be held onto the drum 10 as it is stopped and the web is cut, so that when the core 34 is ' dropped into the nest between the rolls, the lead end will immediately be adhered to the surface of the core and the drums again started up with the lead end of the web following the surface.of the core.
  • the knife having its concave shape, moves along the surface of the front drum 10 into the space between the drums and the lead cutting edge 32 simultaneously cuts the full width of the web in a rapid reliable manner.
  • the intersection of the cutting edge 32 of the knife and the web causes a coaction with the web being held on the stopped drum 10 so that the tension of the web being pulled as the completed roll 15 rolls away from the drums will cause the web to be pulled against the serrated knife to cause the cutting operation.
  • the function of the knife in cutting is not limited to one size of roll, but operates in essentially the same fashion with all sizes and is performed automatically as the finished roll is propelled out of the nest between the drums. All of the functions can be accomplished automatically with the parts operating in sequence.
  • the fresh cores can be brought into position from above or loaded axially into the jaws and this can be done rapidly with adequate space being provided by the carrier located above and in advance of the front drum 10.
  • the knife also functions to sever the tails of the web when the winder is initially threaded without a wound roll resting on the winder drum.
  • the winder is threaded in the conventional manner bringing the full width web and/or slit tails around the suction winder drum in a counterclockwise direction.
  • the knife is rotated counterclockwise with the serrated leading edge moving into a position to capture the threaded tails between the outside surface of the drums 10 and the serrated edge of the knife.
  • the operator then pulls the threaded tails away from the winder and the serrated leading edge of the knife severs the web with the web being held closely between the drum surface and the knife.
  • the tails are severed in a length suitable to continue the automatic operation.
  • the inner concave surface of the knife 31 provides a shield or holder which holds the web captive between the drum and the knife so that the knife performs a dual function of a cutter and safety holder.
  • any loose or frayed ends of the web will be forced to travel along the surface of the drum aided by suction within the drum.
  • the knife is compactly held and constructed requiring a minimum of space for its operational movement between the drums and moves to a noninterfering inoperative position.
