Definitions

  • This invention relates to a coreless winding method and apparatus and, more particularly, to one that produces products without cores using small diameter mandrels on a continuous basis to develop retail size logs from jumbo parent rolls.
  • the winding is performed at alternating positions. This permits the use of small mandrels because each mandrel can be supported at multiple points along it length. Also, the finished wound roll can be decelerated and ejected from the machine while the opposing winding station is winding the next log.
  • DE-A-3239661 that discloses a method according to the preamble of claim 1, teaches a mandrel driven at one end, ie., a center-type winder, in contrast to a surface winder employed in the present invention.
  • the drawbacks to the prior art have been overcome by a method of coreless rewinding according to the characterising part of claim 1.
  • PAPER MACHINE represents a paper making machine of conventional construction. Normally this machine will make use of a pulp slurry being introduced onto a Fourdrinier wire followed by drying rolls to bring the moisture content to about 5%.
  • the jumbo roll J may vary in diameter from about 1.5 to 3 m. (5 to 10 feet) and in length from about 1.2 to 6 m. (4 to 20 feet).
  • the trend is toward wider machines to achieve greater production at the same rate of web speed.
  • the jumbo roll After the jumbo roll has been wound, it is transported usually to a converting area or section where a number of rewinders are located.
  • the instant invention makes use of a surface rewinder such as that indicated previously to be found in US-A-4,828,195. With ever increasing rates of speed of paper machines, it is sometimes necessary to use two or more rewinders to convert the output of a particular paper making machine.
  • the output of the rewinder is in the form of a log having a length equal to the width of the web in the jumbo roll J.
  • the difference is in the diameter because the log L has a diameter corresponding to that of the retail size roll of bathroom tissue, kitchen toweling, etc. This may range variously from about 100 to 250 mm. (4 to 10").
  • the log is processed through a log saw such as that seen in US-E-30,598.
  • a log saw such as that seen in US-E-30,598.
  • the products may take the form of a roll of bathroom tissue P 1 as seen in FIG. 2 or a roll of kitchen toweling P 2 as seen in FIG. 3.
  • These lengths are generally less than about 375 mm (15").
  • the machine has conventional draw rolls and perforator, the draw rolls being seen in US-E-28,353 and the perforator in US-A-2,870,840.
  • the symbol W at the extreme top of the view designates a web coming from pull rolls (not shown) and traveling in partial wrapping engagement with a perforator roll 10.
  • the numeral 11 designates the stationary knife bar cooperating with the perforating bedroll 10 as seen in the above-identified US-A-2,870,840. This results in transverse lines of perforation which, in the U.S., are spaced about 115 mm. (4-1/2") for toilet tissue and 280 mm (11") for kitchen toweling.
  • the web W after having been transversely perforated on the center distances indicated above travels to and in partial wrapping engagement with the principal bedroll 12, i.e., the "transfer" bedroll.
  • the bedroll 12 operates in conjunction with a chopper roll 13 and has several functions.
  • the bedroll is used to determine sheet count in a wound log.
  • the bedroll is engineered for 10 sheets per revolution.
  • a blade mechanism in the bedroll meshes with the blade 14 and the chopper roll 13 to sever the web W and yield the desired count, viz., 350, 500, etc. sheets each about 115 mm (4-1/2") square 280 mm (11") etc.
  • the sheets are defined as lying between adjacent lines of transverse perforation.
  • the blade engagement is along a line of transverse perforation so as to yield the exact count and sheets ahead of the blade, i.e., downstream, are wound onto a roll or log that is completing its winding cycle as at L in the left center of FIG. 4.
  • the portion of the web trailing the engaging blades is carried to a mandrel 15 in the position A in FIG. 4 -- see the right hand side of the view.
  • the log L in the process of being completed is in the position B which is to the left in FIG. 4.
  • FIG. 4 Winding Operation -- Generally
  • axially spaced arms 16' which rotatably support winding rolls or drums 17', 18', move away from bedroll 12 to allow for the increase of the wound log diameter -- compare the angular positions of the arm 16' to the left with the arm 16 to the right, i.e., in position A.
  • winding drums 17', 18' are pivotally mounted as 19' and 20' so as to move during the course of the wind-and also accommodate the increase in roll diameter -- again compare the positions of the winding drum 17', 18' with the positions of the winding drums 17, 18 in position A and the change in angularity of the pivot arms -- the arm supporting winding drum 17 being designated 21.
  • drive means for the winding drums 17, 18 and 17', 18' which can include prime mover means on each of the arms 16, 16' such as an electric motor and belt and pulley systems along with suitable clutches for controlling the duration of the wind cycle and stopping of the winding upon finishing of the winding cycle.
  • the activity depicted at the lower left of FIG. 4 occurs.
  • the arm 16' pivots counterclockwise about a pivot 29 so as to position the log L in a stripping position wherein the arm 16' now has the orientation designated 16''. This is achieved by virtue of rotating the arm 16' and thus the mandrel 15' through the arc 22. This brings the mandrel 15' into a position in which the wound roll or log L is stripped off the mandrel 15' by means 23 and which can be seen in greater detail in FIG. 5.
  • a portion of the support arm 16 or 16' pivots to allow the finished log to be ejected from the wind mandrel.
  • the portion of the arm 16, 16' which pivots to allow clearance for ejecting the log will return to its closed position after the log has cleared the mandrel end. Thereafter the arm 16 or 16' will return to lie in close proximity to the bedroll to receive the start of the next log.
  • the rewinder makes use of standard draw rolls and a perforator such as is seen in the embodiment of FIG. 4.
  • the web W is seen to travel in partial wrapping engagement with the bedroll 112 which functions in conjunction with a chopper roll 113 having a knife 114 to create the end of one log and start the beginning of another.
  • the bedroll 112 is used to determine the number of sheets in a wound log. Again, the bedroll 112 is usually engineered for ten sheets per revolution. When the bedroll 112 attains the correct number of revolutions, a blade mechanism in the bedroll 113 cooperates with the blade 114 and the chopper roll 113 to sever the web.
  • the portion of the web ahead of the blade is wound into a log L in the left hand position.
  • the portion of the sheet trailing the blade 114 is picked up by a vacuumized drive roll 117 and transferred to a second vacuumized drive roll 118. This carries the leading edge of the web to the mandrel 115 to start the next winding cycle.
  • the winding cycle is achieved by the vacuumized roll means 117, 118 which are radially slotted and innermeshed as can be appreciated from the showing in the FIG. 6 -- thus creating a cradle or nip where their peripheries intersect. These can be considered “ring” rolls because of the axial interruption and interlacing.
  • these ring rolls 117, 118 are decelerated to stop the wound log and to prepare for ejecting the log. This is illustrated at the extreme right and left hand positions in FIG. 6 and here it will be noted that the arms 116, 116' are slotted as at 129 and 129' for the two arms. The arms are pivotally mounted on the frame to move from an essentially 12 o'clock position to a 3 or 9 o'clock position where the mandrel carried in the slot is engaged with a corresponding slot 130, 130' in the respective stripping means 123 and 123'.
  • the arms 116, 116' for the right and left hand positions rotate to the log ejection station 123, 123'.
  • a portion of the support arm 116 or 116' pivots to allow the finished log to be ejected from the wind mandrel 115 or 115'.
  • the portion of the arm 116, 116' that pivots to allow clearance for ejecting the log will return to its closed position after the log has cleared the mandrel end.
  • the arms return the mandrel 115, 115', as the case may be, to the wind position.
  • the mandrel is slidably mounted in the slot 129 or 129' as the case may be and thus can move essentially radially outwardly relative to the bedroll 112 to accommodate the build-up of convolutely wound layers.
  • draw rolls 131 which are upstream of the perforator 10, 11.
  • rider rolls 132 and 132' which are pivotally mounted on the machine frame as at 133 and 133'.
  • the rider roll 132 cooperates with the rolls 117 and 118 to provide a three-roll cradle for the surface winding.
  • the rider roll 132' cooperates with the winding rolls 117' and 118'.
