Definitions

  • the present invention relates to a towel dispenser. More particularly, the present invention relates to a paper towel dispenser.
  • first and second rolls of towel for dispensing from a paper towel dispenser.
  • the second roll may be automatically transferred onto a support roller for dispensing.
  • the second roll is generally moved to the first roll position and a replacement second roll inserted.
  • US 6,314,850 discloses a paper towel dispensing apparatus having a rotatable member for loading towel from a second roll onto a support roller when towel from a first roll is depleted.
  • a clip is provided at each end of the rotatable member to secure the towel from the second roll in position and, upon depletion of the towel from the first roll, the rotatable member is brought into contact with the support roller and rotated to supply towel from the second roll to the support roller.
  • a spring is provided at each end of the support roller to bias the rotatable member against the support roller.
  • the towel may rip as the rotatable member rotates, preventing the towel from being transferred successfully onto the support roller. Moreover, if the springs for biasing the rotatable member towards the support roller are not matched, the towel may not be uniformly pressed against the support roller and it may skew in relation to the support roller leading to fouling of the apparatus.
  • US 6,826,985 discloses a paper towel dispensing apparatus for dispensing towel from first and second rolls from a support roller.
  • the apparatus comprises a dispensing roller and a transfer roller for supplying towel to the support roller.
  • Towel from the first roll is supplied to the support roller via the transfer roller.
  • a channel extends through the dispensing roller for receiving a lead end of towel from the second roll and a series of raised portions provided on the dispensing roller contact the towel carried by the transfer roller and prevent rotation of the dispensing roller until the towel from a first roll is depleted.
  • the dispensing roller is brought into contact with the transfer roller and rotated, thereby loading the towel from the second roll onto the transfer roller.
  • a further limitation of known paper towel dispensers is that they typically dispense a sheet of towel having a length corresponding to the circumference of the support roller during each operational cycle.
  • a cutter blade is actuated to cut the paper towel each time the support roller completes a single complete revolution.
  • the diameter of the support roller has to be relatively large thereby increasing the size of the towel dispenser.
  • the present invention attempts to overcome or ameliorate at least some of the problems associated with the prior art dispensers.
  • the present invention relates to a paper towel dispensing apparatus for dispensing paper towel from a first roll, the apparatus comprising:
  • the towel biasing device By coupling the towel biasing device to the cover, it may automatically be displaced to said first position when the cover is closed. Likewise, the towel biasing device may automatically be displaced to said second position when the cover is opened.
  • the towel biasing device is preferably positioned adjacent the support roller when in said first position; and is preferably displaced from the support roller when in said second position.
  • the movement of the towel biasing device to either said first position or said second position could be performed manually.
  • the towel biasing device may be coupled to the cover such that it is displaced to said second position by the action of opening the cover, but returning the towel biasing device to the first position is performed manually before the cover is closed.
  • the towel biasing device could be manually moved to the second position after the cover has been opened, but the towel biasing device coupled to the cover such/that it is returned to the first position by the action of closing the cover.
  • the towel biasing device is coupled to the cover such that it is moved to the first and second positions by the action of closing and opening the cover respectively.
  • the towel is typically provided between the support roller and the towel biasing device for dispensing.
  • the cover is opened and the towel biasing device displaced to said second position to facilitate the positioning of towel between the support roller and the towel biasing device.
  • the cover is then closed and may thereby return the towel biasing device to its first position adjacent to the support roller and may bias the towel against the support roller.
  • the towel biasing device could be mounted on one or more arms coupled to the cover. Preferably, however, the towel biasing device is mounted on the cover.
  • the towel biasing device comprises a towel biasing member, such as an elongate member or plate, for engaging the towel and biasing the towel against the support roller.
  • the biasing member is pivotably mounted.
  • the biasing member is pivotable about an axis substantially parallel to a rotational axis of the support roller.
  • a spring could be provided for biasing the biasing member towards the support roller.
  • the biasing member may be biased towards the support roller by gravity.
  • the towel transfer mechanism comprises a movable control member for cooperating with the towel from the first roll.
  • the control member is referred to hereafter as a floating member but the terms are interchangeable.
  • the floating member could be slidably mounted, for example in a pair of elongate channels.
  • the floating member is pivotably mounted.
  • the floating member is preferably pivotable about an axis substantially parallel to the rotational axis of the support roller.
  • a pathway for receiving towel is provided between the floating member and the towel biasing device. The pathway preferably extends at least substantially across the width of the support member. In use, a length of towel from the second roll may be located in said pathway ready for transfer onto the support roller when the towel from the first roll is depleted.
  • the floating member operatively controls actuation of the towel biasing device.
  • the movement of the floating member for example upon depletion of the towel from the first roll, preferably actuates the towel biasing device to bias towel onto the support roller.
  • a first side of the floating member is preferably provided with at least one projection for engaging the towel from the first roll.
  • the at least one projection is preferably at least one fin or rib.
  • a corresponding recess is preferably provided in the support roller for receiving the or each projection.
  • the recess is preferably an annular groove or an aperture.
  • a second side of the floating member is preferably suitable for supporting the towel from the second roll. The second side of the floating member preferably faces the towel biasing device.
  • the at least one projection contacts the towel from the first roll on the support roller and is prevented from locating in the corresponding recess (or recesses) provided in the support roller.
  • the at least one projection locates in the recess in the support roller and the floating member moves towards the support roller.
  • the resulting movement of the floating member may actuate the towel biasing device.
  • the movement of the floating member allows the biasing member to bias the towel from the second roll against the support roller.
  • towel from the second roll may be transferred onto the support roller by the towel biasing device.
  • the support roller is preferably rotated by applying a pulling force to the end of the towel being dispensed.
  • a manual drive such as a wheel or handle, may be provided for rotating the support roller.
  • the manual drive may be used to rotate the support roller to draw towel from the second roll through the dispensing apparatus once it has been transferred onto the support roller by the transfer mechanism.
  • a spring element may be provided automatically to rotate the support wheel once the towel from the second roll has been transferred.
  • the dispensing apparatus preferably comprises a tensioning arm for maintaining the towel under tension.
  • the tensioning arm is preferably suitable for engaging the towel between the biasing member and the roll of towel.
  • the tensioning arm may form part of the towel biasing device.
  • the cover is preferably pivotably mounted.
  • the cover is pivotable about an axis substantially coincident with the axis about which the first roll or the second roll is rotatable. If the towel biasing device is mounted on the cover this arrangement is advantageous since it reduces the likelihood of the towel biasing device fouling on the second roll of towel when the cover is opened or closed.
  • a portion of the cover may be received inside the housing of the dispensing apparatus when the cover is pivoted to an open position.
  • the paper towel dispensing apparatus preferably comprises a cutter blade for cutting the towel from said first and second rolls.
  • the cutter blade could be fixedly mounted, for example on the housing.
  • the cutter blade is movable to a cutting position.
  • the cutter blade may be slidably or pivotably mounted.
  • the rotation of the support roller preferably actuates the cutter blade and moves it to said cutting position.
  • the cutter blade preferably comprises a tip which extends, when the cutter blade is in the cutting position, at least in part in a direction opposite to the direction of rotation of the support roller when the towel is dispensed.
  • the tip of the cutter blade is therefore disposed against movement of the towel as it is dispensed, which assists in the cutting of the towel.
  • the cutter blade has a curved cross-sectional profile to orient the tip rearwardly relative to the direction of rotation of the support roller when the cutter blade is actuated.
  • the tip may be formed at a distal end of the cutter blade such that it is displaced from said support roller.
  • the cutter blade preferably comprises a plurality of said tips.
  • the cutter blade may be mounted on the housing, but it is preferably mounted in the support roller. Preferably, at least a portion of the cutter blade extends outwardly beyond the outer circumference of the support roller when it is in said cutting position. The cutter blade preferably extends substantially radially outwardly when it is in said cutting position. A stop or guide member is preferably provided to limit the travel of the cutter blade so as not to pivot beyond said radial position. Preferably, the cutter blade is retractable at least substantially into an interior of the support roller.
  • the cutter blade is preferably actuated each time the support roller completes a plurality of whole revolutions.
  • the cutter blade may be actuated each time the support roller completes two (2), three (3) or four (4) revolutions. This is advantageous since the length of towel dispensed may be larger than the circumference of the support roller. For example, if the cutter blade is actuated each time the support roller completes two revolutions, the length of towel dispensed will be twice the circumference of the support roller. Thus, the diameter of the support roller may be smaller than those of prior art dispensers.
  • a cutter blade actuator is preferably provided.
  • the actuator preferably comprises a gear train.
  • the gear train preferably couples the support roller to an axle on which at least one cam is mounted.
  • the cutter blade is preferably provided with at least one cam follower for following said at least one cam.
  • the present invention relates to a method of servicing a paper towel dispensing apparatus as described herein, the method comprising the steps of:
