  • the controller 270 can be in communication with the dancer rolls 274, 276 to receive data relating to the tension in the wrap material 112 between the supply roll 176 and the drive assembly 184 and between the supply roll 224 and the drive assembly 230.
  • the controller 270 can determine whether the supply rolls 176, 224 are rotating at a desired rotational speed. In addition, if the supply rolls 176, 224 are not rotating at a desired rotational speed, the controller 270 can be programmed to increase or decrease the rotational speed of the supply rolls 176, 224 to ensure that wrap material 112 is continuously supplied to the wrap station 146.
  • the controller 270 can also be programmed to increment the rotational speed of the supply rolls 176, 224 in response to the changing diameters of the supply rolls 176, 224 as wrap material 112 is consumed. In these embodiments, the controller 270 can be programmed to increase the rotational speed of the supply rolls 176, 224 as wrap material 112 is consumed and as the diameters of the supply rolls 176, 224 decrease.
  • the bander apparatus 110 can include position sensors (e.g., photo gates, position switches, etc.) 280 positioned along the conveyor path 115 to record the position of the stacks 114.
  • the controller 270 is operable to adjust the operating speed of one or more of the lower and upper feed conveyors 118, 120, the lower and upper discharge conveyors 154, 156, the unwind drive assemblies 180, 228, the drive assemblies 184, 230, and the cutting assemblies 192,240 based upon stack position data received from the position sensors 280 to ensure that the wrap sheets 204, 256 are properly aligned on the bottom and top surfaces of the stacks 114.
  • the controller 270 can also be programmed to adjust the operating speed of one or more of the lower and upper feed conveyors 118, 120, the lower and upper discharge conveyors 154, 156, the unwind drive assemblies 180, 228, the drive assemblies 184, 230, and the cutting assemblies 192, 240 to accommodate differently sized stacks 114. In some such embodiments, the controller 270 can be programmed to adjust one or more of the above-mentioned operating speeds based upon stack size data received from the sensors 280.
  • the bander apparatus 110 can be operated to cut wrap sheets 204, 256 having a number of different sizes corresponding to a number of differently sized stacks 114. Specifically, the bander apparatus 110 can be operated to cut wrap sheets 204, 256 having a length measured between a leading edge and a trailing edge of 1.8 m (six feet) or more. The bander apparatus 110 of the present invention can also be operated to cut wrap sheets 204, 256 having a length measured between a leading edge and a trailing edge of 0.15m (six inches) or less.
  • the bander apparatus 110 can be operated to cut wrap sheets 204, 256 having still shorter lengths, with the minimum length of the wrap sheets 204, 256 being limited only by the distance between the drive assemblies 184, 230 and the wrapping station 146.
  • conventional banding apparatuses pinch the wrap sheets between conveyors and stacks of web product so that the conveyors can pull the wrap sheets into engagement with the stacks.
  • Such conventional banding apparatuses are unable to pinch shorter wrap sheets and are therefore unable to wrap relatively small stacks.
  • the bander apparatus 110 of the present invention can wrap shorter stacks than conventional banding apparatuses because, among other things, the drive assemblies 184, 230 positively feed wrap sheets 204, 256 toward the wrapping station 146 and therefore do not require longer wrap sheets 204, 256.
  • Figs. 6-9 best illustrate the operation of the bander apparatus 10 of the present invention.
  • the lower and upper feed conveyors 118, 120 move stacks 114 along the conveying path 115 toward the wrapping station 146.
  • the pull rolls 186, 188 of the first wrapping assembly 170 draw web material 112 from the supply roll 176 and feed the web material 112 toward the cutting assembly 192.
  • the pull rolls 186, 188 feed the wrap material 112 between the anvil 194 and the cutting roll 196 and direct the wrap material 112 upwardly toward the wrapping station 146.
  • the guide 208 also or alternately directs the leading edge of the wrap material 112 upwardly and laterally toward the conveying path 115.
  • the lower feed conveyor 118 moves a stack 114 across the upper surface 210 of the guide 208 and onto the leading edge of the wrap sheet 204, pinching the leading edge 112 of the wrap material 112 between the lower discharge conveyor 154 and the leading edge of the stack 114.
  • the lower discharge conveyor 154 and the drive assembly 184 then cooperate to feed the wrap material 112 through the wrapping station 146 until the blade 202 of the cutting roll 196 is rotated into engagement with the blade 200 of the anvil 194, thereby cutting a wrap sheet 204 from the wrap material 112.
  • the lower discharge conveyor 154 continues to feed the wrap sheet 204 upwardly toward and along the conveying path 115 until the wrap sheet 204 is positioned on the lower surface of the stack 114 with the leading edge of the wrap sheet 204 being aligned with the leading edge of the stack 114 and the trailing edge of the wrap sheet 204 being aligned with the trailing edge of the stack 114.
  • the pull rolls 232, 234 of the second wrapping assembly 172 draw web material 112 from the supply roll 224 and feed the web material 112 toward the cutting assembly 240. As shown in Figs. 6 and 7 , the pull rolls 232, 234 feed the wrap material 112 between the anvil 242 and the cutting roll 244 and direct the wrap material 112 downwardly toward the wrapping station 146. In embodiments having a guide 260, the guide 260 also or alternately directs the leading edge of the wrap material 112 downwardly and laterally toward the conveying path 115.
  • the upper feed conveyor 120 moves a stack 114 across the lower surface 262 of the guide 260 and onto the leading edge of the wrap sheet 256, pinching the leading edge of the wrap material 112 between the upper discharge conveyor 156 and the leading edge of the stack 114.
  • the upper discharge conveyor 156 and the drive assembly 230 then cooperate to feed the wrap material 112 through the wrapping station 146 until the blade 252 of the cutting roll 244 is rotated into engagement with the blade 250 of the anvil 242, thereby cutting a wrap sheet 256 from the wrap material 112.
  • the upper discharge conveyor 156 continues to feed the wrap sheet 256 downwardly toward and along the conveying path 115 until the wrap sheet 256 is positioned on the upper surface of the stack 114 with the leading edge of the wrap sheet 256 being aligned with the leading edge of the stack 114 and the trailing edge of the wrap sheet 204 being aligned with the trailing edge of the stack 114.
  • the stacks 114 are directed downstream toward wrap folders (not shown, but readily understood by one skilled in the art), which fold sides of the bottom wrap sheets 204 upwardly and around at least a portion of the stacks 114 and which fold sides of the top wrap sheets 256 downwardly and around at least a portion of the stacks 114.
  • the stacks 114 are directed further downstream toward adhesive applicators (also not shown, but readily understood by one skilled in the art), which apply adhesive to overlapping portions of the top and bottom wrap sheets 204, 256 to couple the top and bottom wrap sheets 204, 256 and to bind the wrap sheets 204, 256 around the stacks 114.
  • adhesive applicators also not shown, but readily understood by one skilled in the art
  • the bander apparatus 110 can also include a guide assembly 290, which can be located along the conveying path 115 between the lower and upper discharge conveyors 154, 156.
  • the guide assembly 290 can include a roller 292 and a biasing mechanism 294, which forces the roller 292 outwardly and into the conveying path 115.
  • the roller 292 engages the stacks 114 and aligns the sheets 116 in the stacks 114.
  • the rollers 292 can also force folded sides of the top wrap sheets 256 downwardly and around at least a portion of the stacks 114 and can force folded sides of the lower wrap sheets 204 upwardly and around at least a portion of the stacks 114 to form a tighter wrap around the stacks 114.
  • the guide assembly 290 can be located downstream from adhesive applicators and is operable to press the adhesive and the wrap sheets 204, 256 together.
  • the outer surface of the roller 292 can be machined (e.g., knurled, grooved, and the like).
  • the outer surface of the roller 292 can be at least partially covered with a high friction coating, such as a rubber coating.
