Definitions

  • a secondary slitter rewinding machine with much greater flexibility is therefore an object of the invention.
  • This type of slitter rewinder has the upper and lower rewind mandrels fixed to the driven side of the machine slitter section.
  • the slitter section also contains the machine pull rolls, idler rolls and contact rolls, as well as any web spreading devices (bowed roll) and the male knives and the female knives, and any trim extraction system.
  • the upper and lower rewind mandrels must be supported at the non-driven end. This is accomplished by fitting rewind mandrels support arms that are in the raised configuration during rewinding, and lowered to allow the rewound rolls to be unloaded from the rewind mandrels when rewinding is complete.
  • the position of the rewind mandrel support arms is controlled by a mechanical mechanism that is operated by a pneumatic cylinder.
  • the slitter section also contains the machine pull rolls, idler rolls and contact rolls, as well as any web spreading devices (bowed roll) and the male knives and the female knives, and any trim extraction system.
  • This type of slitter rewinder has an upper and lower turret assembly fixed to the driven side of the machine slitter section. Each turret assembly has two rewind mandrels.
  • the slitter section also contains the machine pull rolls, idler rolls, contact rolls and carriage assembly, as well as any web spreading devices (bowed roll) and the male knives and female knives and any trim extraction system.
  • the upper and lower turret will have one rewind mandrel in the rewinding position (in board rewind mandrel) and the other rewind mandrel in the unloading /core loading position (outboard rewind mandrel).
  • the upper and lower rewinding mandrels must be supported at the non-driven end. This is accomplished by fitting rewind mandrel support arms. The position of the rewind mandrel support arms is controlled by a mechanical mechanism that is operated by a pneumatic cylinder.
  • the contact rolls are mounted in the carriage assembly.
  • the carriage assembly has sensors that monitor the increase diameter of the rewinding rolls.
  • the carriage assembly tracks the way from the rewind mandrels as the diameter of the rewinding rolls increases. This changes the geometry and web length between the knives and the rewound package and can affect the quality of the finished product.
  • the slitter module incorporates a platform which serves to position one or both of said unwind and/or rewind modules. This allows the platform to not only facilitate the displacement of the slitter module in use but provides an advantageous means of positioning the unwind and rewind modules.
  • control means for both said unwind module and said slitter module are provided as part of the unwind module. This reduces the requirements for multiple control modules whilst achieving advantageous versatility of combinations of the various modules.
  • said unwind modules are selected from a plurality of unwind modules with distinct unwind roll capacities. This allows the apparatus to be relatively straightforwardly changed from a standard duty mode of operation to heavy duty mode of operation without requiring the replacement of other modules.
  • one or more of said supporting frames incorporates side panels; whereby said side panels incorporate releasable attachment means for facilitating the attachment and/or the release of the panels of adjacent modules.
  • the invention provides a method of processing a web comprising the steps of: providing an unwind module with an unwind supporting frame for supporting an unwind roll of web material; a slitter module with a slitter supporting frame incorporating one or more slitters; and a rewind module with a supporting frame incorporating one or more rewind shafts for supporting, in use, rewound packages; said unwind supporting frame, said slitter supporting frame and said rewind supporting frame being distinct frames; and separating a selected unwind module and replacing it by a further unwind module.
  • the invention provides a method of processing a web comprising the steps of: providing an unwind module with an unwind supporting frame for supporting an unwind roll of web material; a slitter module with a slitter supporting frame incorporating one or more slitters; and a rewind module with a supporting frame incorporating one or more rewind shafts supporting, in use, rewound packages; said unwind supporting frame, said slitter supporting frame and said rewind supporting frame being distinct frames; and separating a selected rewind module and replacing it by a further rewind module.
  • Figure 1 illustrates the flexibility achieved by the unwinding and rewinding arrangement.
  • a single operating system may be provided with functions and/or controls that can be selected on or off in order to allow the machine to operate in several modes of operation. These modes of operation may be twin rewind mandrel machines, single rewind mandrel machines, and the turreting rewind mandrel machines.
  • FIG 1 two potential unwind modules are illustrated such as a standard duty unwind module 1 and a heavy duty unwind module 2.
  • a slitter module which may be common to any of the variants of the machine is provided as reference 3.
  • Three rewind modules 5 and 6 are envisaged.
  • Rewind module 4 is a twin shaft (duplex) module.
  • Rewind module 5 is a dual turreting module.
  • Rewind module 6 is a single turret module.
  • Each one of the modules incorporates a necessary supporting frame.
  • the unwind modules incorporate side panels which are substantially L-shaped.
  • the size of the arms and the drive chain fitted vary from one module variant to another.
  • the main control cabinet for the unwind and slitter modules is incorporated into the module reducing the machine footprint and the need for off machine cabinets.
  • releasable attachment means may be provided such as appropriately formed tongues and grooves.
  • each variant module may be made up of a rewind shaft section and a control cabinet.
  • a cabinet may be provided which may be common between all three variations.
  • the module locates from the platform to ensure consistency of position and alignment.
  • the electrical system of each module may be linked through a plug and socket arrangement in order to ease changeover at a customer site.
  • the rewind module cabinet may contain the HMI (human machine interface) and may be loaded with standard software containing all options and variants which are simply turned on and/or off dependent upon the configuration of the machine.
  • HMI human machine interface
  • the unwind module holds an unwind roll 13 of web material.
  • the unwind module may either be single driven or double driven dependent upon the required level of torque.
  • the unwind module is self-standing and remains in position during its use. Since the unwind module is distinct from the slitter module, the unwind module may readily be replaced by an alternative unwind module.
  • the slitter module 11 is provided with a platform 14 with predefined means for positioning the unwind module relative to the slitter module. It may therefore be sufficient to simply position the unwind module against a predetermined indexing position of the platform for correct operation to be achieved.
  • Platform 14 incorporates guides or rails 15 to facilitate the displacement of the slitter module 11 towards or away from its adjacent modules as illustrated by the double ended arrow.
  • the slitter module incorporates a motor which displaces the entire slitter module dependent upon the size of the unwound packages.
  • the displacement of the slitter module of the invention allows the distance between the knife and the rewound packages to be constant throughout the slitting and rewinding operation. This distance may for example be maintained at approximately 1 m (meter) whilst in the prior art the distance would for example reduce from 2m to 1.7m as the rewound packages increased in diameter.
  • the configuration of a displaceable slitter module relative to a fixed rewind module allows this distance to be constant throughout the operation which allows an increase in the cut quality and facilitates more rapid throughput.
  • a contact roller 16 may be provided as part of the slitter module to facilitate the squeezing out of air in the rewound packages.
  • the rewind module of Figure 3 is a twin rewind mandrel module with a single upper and lower mandrel respectively referenced 17 and 18. Following the blade slitting operation 19, an upper and a lower series of rollers respectively referenced 20 and 21 support respectively the upper and lower portions of the web prior to being rewound on mandrels 17 and 18.
  • a further guide to assist with the linear motion of the slitter module may be provided as an upper rail between the slitter module and the rewind module.
