Definitions
- This invention provides an improvement in the basic apparatus and also the variations of the same as previously discussed.
- the invention therefore provides a corrugated board making apparatus capable of forming corrugated boards having two fluted mediums bonded together at the flute tips, comprising two pairs of corrugating rolls synchronised so that the two fluted mediums are oriented for precise flute tip to flute tip bonding, wherein cooperating end gears are provided on the corrugating rolls which orientate the fluted mediums for flute tip to flute tip bonding.
- the end gears are provided specifically on the corrugating rolls which co-operate tip to tip and bring the corrugated mediums together for tip to tip bonding.
- a set of end gears is fitted to each end of the said corrugating rolls.
- end gears advantageously aids in maintaining identical surface speed at the tips of the flutes to be bonded, thus resulting in the precise alignment of the corrugating rolls to each other.
- the alignment of the flute tips of the respective corrugated mediums is achieved, which is essential in order to obtain consistent enhancement of board performance and maximum reduction in medium and liner weights.
- End gears are preferably but not essentially fitted to each end of each pair of central corrugating rolls and consist of one full face gear and one split face gear to allow . adjustment of backlash.
- the end gears are preferably abutting end gears and are preferably installed a short distance from the grooved face of each corrugating roll advantageously assisting in reducing the twisting of shafts.
- the use of abutting end gears allows the use of conventional vacuum corrugating rolls with standard sized trunnions and minimises the torsional deflection which generally occurs.
- By providing abutting end gears to both ends of the corrugating rolls the general rigidity of the apparatus and the reduction in the twisting of the shafts is further enhanced.
- the end gears may be non-abutting end gears or can be fitted outside the vacuum collectors and also outside the machine frames.
- Non-abutting gears can be used when the corrugating rolls have larger trunnions and thus the ability to resist the high torsional stresses arising from the point to point pressure occasioned during the tip to tip bonding process.
- the end gears are preferably precision ground so that the intermeshing is precise.
- the end gears can be spur gears or helical gears.
- the gears may be split. If there are gears provided at each end they are preferably split at each end. The split gear may then mate with a gear of larger face width on the other corrugating roll. This arrangement assists in taking up backlash and allows transmission of at least 50% of the applied torque, thus preventing, further the twisting of the corrugating rolls and shafts.
- Figure 1 shows a schematic view of a single facer unit of the kind disclosed in Australian Patent No. 609089.
- Figure 2 shows a cross-section view of the corrugating rolls with abutting end gears attached.
- Figure 1 illustrates a single facer unit of the kind disclosed in Australian Patent
- the corrugating medium, 1 and 2 maintained on mill roll stands (not shown) and generally passed over a preheater (not shown) is fed onto one (items 3 and
- the medium, 1 and 2 is corrugated and then adhesive is applied to at least one of the surfaces of 1 or 2, by an adhesive station 7.
- the corrugated medium, 1 and 2 is then joined together flute tip to flute tip, when brought together by corrugating rolls 4 and 6.
- the two combined corrugating mediums are fed onto the carrier roll 12 and after glue is applied to the flute tips, they are transported to the bonding zone wherein the liner 9 is brought into contact with the flute tips and heat applied by heater 11.
- the carrier rolls 12 then transports the combined liner and mediums to a point where the product is fed into an inclined transport conveyor 14 for discharge on to the corrugator bridge.
- the vacuum collectors 17 and connections therefrom to the corrugating roils 4 and 6 can pass through the end gears 15A, 15B, 16A and 16B to communicate with the corrugating rolls 6 and 4.
- the vacuum collectors 17 are spring- loaded by spring arrangement 19 to ensure a secure but resilient contact between the end gears (15A, 15B, 16A and 16B) and the vacuum collector system 17.
- the end gears need not always abut the corrugating rolls and this is dependent on the diameter of the corrugating rolls with larger diameter shafts.
- the end gears need not abut the rolls and can be even housed outside of the main housing.
- vacuum is not used to assist in retaining and carrying the cardboard on the corrugating roll and the alternative fingers are used, it is possible to separate the end gears away from the corrugating rolls, since larger rolls can be used.
- the diameter of the corrugating rolls and shafts may be limited in order to produce the desired flute pitch and depth. In these cases it may be necessary to abut the end gears in order to maximise the rigidity of the apparatus.
- split spur gear 16A is extended to assist in taking up backlash and allow transmission of the applied torque.
- face width of the end gears is governed by the braking torque required which as a general rule is at least three (3) times the drive torque created.
- End gear 16A and 16B is driven by its cooperation with end gears 15A and 15B and drives the carrier rolls 12 via a ring gear (not shown) attached to the carrier roll 12.
- the end gears can drive a toothed belt if used.
- the end gears 15A and 15B and 16A and 16B may be fixed to the shafts of the corrugating rolls 4 and 6 by any locking assembly, for example multi-taper lock sleeves, item 21.
- the only requirement of the locking assembly is that the gears are precisely retained in position to transmit high peripheral forces without circumferential movement.
- fixing screws 20 may be used which also allow for adjustment of the gears relative to each other in order to reduce backlash.
- fixing screws 20 can also be incorporated on split gears 16A and 16B.
- the end gears 15A, 15B, 16A and 16B depending on their proximity to the corrugating rolls may have a shroud (not shown) shielding the board being processed and preventing entanglement of the board in the rotating end gears.
- end gears must be applied to at least the corrugating rolls which are directly involved in flute-tip to flute-tip bonding
- end gears can be applied to other rolls such as carrier rolls, or toothed belt mechanisms.
- the frame 18 may also be reinforced and/or improved in order to increase frame rigidity and thus generally greater apparatus rigidity.
