Abstract
Abstract This invention provides an improved web transfer mechanism in a paper roll towel dispense of the type having a primary roll and a reserve roll of paper toweling. The transfer mechanism comprises a cradle for supporting the primary roll that is counterbalanced by an element for tucking the leading end of the reserve roll into the nip between feed rollers. As the primary roll becomes depleted, the counterbalancing force of the roll decreases, causing the tucking element to gradually approach the leading end of the reserve roll until the element finally engages the end and introduces it into the nip. In a preferred embodiment, the device includes a damper mechanism to prevent premature introduction of the leading end caused by the tendency of the primary roll to rise above the cradle by a sudden pull on the toweling.
Description
Pa~r Roll Towel Dispenser Backqround of the InYention Thi~ invention i~ a dev-lce for di~penslny ~heet material ~equentially ~rom a pcimary roll and a re~4rve roll. Such device~ are u~ed iu public restroom8 for di~pen~ing ~a~er toweling from a roll.
AB ~hOWn in U.S. Paeent~ 2,g3O,664 tO LiebigCh, 3,228,3~7 to Craven, 3,917,191 to Graha~ et al, 4,010,909 to Bastian, and 4,378,912 to Perrin et al, suc~ devices ~ompcise a cabinet having an opening through which the sheet material is dispensed, mean~ foc supporting the primary and reserve rolls, feed means including a pair of roll6 forming a nip through which the sheet material passes, and means for introducing sheet material fro~ the ceserve roll into the nip responsive to depletion of primary roll sheet material. This invention provides improved means foc introducing 5heet material into the nip responsive to depletion of primary coll sheet material.
Summary of the Invention The improved device o~ this invention has a balanced lever mounted foc rotational movement a'oout a fulcrum. The portion of the lever to one side of the fulcrum comprises a ccadle for supporting the primary roll and the portion of the lever to the other side of the fulcrum comprises an element for tucking sheet material from the reserve roll into the nip. The lever is balanced such that when the ccadle suppoct6 a primary roll '~
~L~
that has not been 3ubstantially depleted, the tucking element i8 raised above tho nlp (lnactlve po~lt~on) and wh~n th~
primary roll ha~ been ~ubstantially depleted, the tucking element i~ lowered to introduce sheet material from the resecve ~oll into the nip.
In a pcef~rred embodiment, Che device include~ a damp~r mechaniSm to counteract the tendency of the primary roll to momentarily rise up in re8ponse to a sudden pull on the primary roll sheet matecial. The damper mechanism compcises a cam element that engages a cam follower. The cam i5 positioned so that a~ the pcimary roll attempts to rise up in respon~e to a sudden pull on the primary roll s~eet material, the cam engages the pcimary coll sheet material, with the cesult that the focce o the 5heet material is transferred to the cam follower such that the tucking element is maintained in the raised position.

De~ailed Descripticn Referring to the dcawinq~, the device of the invention include a cabinet 10, which i~ shown in phantom in Figure 1.
Located within the cabinet 10 are a pcimary roll 12 and a reserve roll 14 of sheet material in the form of paper toweling. The pcimary roll 12 is supported on a cradle 16.
The ce6erve roll 14 is preferably of the type shown in U.S.
Patent 3,038,598. being wound about a core 18 and ha~ing a bearing receptacle 20 formed in one end o~ the roll 14 to de~ine a bea~ing wall of layer~ of paper toweling. A bearing member 22, mounted on the sidewall o~ the cabi~et, projects inwardly to bea~ing receetacle 20 to support the reserve roll 14. ~he other end of the reserve roll is 6upported by a bearing mechani5m (not 5hown) at the other side of the cabinet. When enough toweling has been removed for the bearing receptacle 2~ to disappear, the partially depleted ~oll will fall down onto the cradle 16 to become the primary roll. In due course an attendant would open the cabinet and install a new reserve roll. However, the rO118 may be of any type and `` ~.3~
need not have the above-desc~ibed drop-down ~eature, in whlch Ca8Q the attendant would manually remove th~ partlally depleted roll and place it on the c~adle befor~ in~tallin~ a new resQrve roll .
A~ seen in Figure 2, the device cor~prises faRd means including a pair of selectively rotatable rollecs 24, 26 which form a nip through which th~ sheet material is draw~ upon rotation of the collers. The rollers are mounted for rotation i~ ~ockee~ (~ot shown) at the side~ of the ~abinet. ~echani~m~
for rotating the rollers are well known and therefore are not illustra~ed.
The cradle 16 is afeixed to a turninq ba~ 28, which is supported for rotational movement by an axle 30, which is supported by sockets at the side walls of the cabinet. Also affixed to the turning ba~ 28 is an element 32 for tucking sheet material from the reserYe roll into the nip between the rollers 24, 26. The tucking ele~ent includes an arm 33 having a tuckec blade 34 positioned above the nip between the rollers 24, 26. The arm 33 is preferably mounted for pivotable movement. Together, the cradle 16 and the tucking element 32 for~ a seesaw-like lever that rotates about the axle 30. whi~h is the fulcrum of the lever.
In a preferced embodiment, the device includes a damper mechanism comprising a cam 36 pivotally mounted on the cabinet 10 and a cam follower 3B that engages the cam 36 and is affixed to the turning bar 28 for rotational movement with the tucking element. When the primary roll sheet material is dispensed by ~ 3~ 2 bei~g pulled forward, th9 force o the ~h~et materlal act~
against a projection 40 of the cam 36 and i8 tcanaf~rred to the ~am followsr 38 by a roller 42 forming part of the ca~ 36. ~
~hown ~n Figure 6, the foree of the sheet ~aterial on the cam ~ollower keep6 the tucking element rai6ed above the ni~, th~ceby preventing pcematura introduction o~ ~heet material fro~ the re~erve roll i~to the nip~
In opecation of the device, towelin~ dispensed fro~ the primary coll passes fir~t throu~h the nip between rollec~ 24, 26 a3 best seen in Figure 4. Prior to web transfer, the initial end of toweling 44 from the reserve roll will have been placed undec the tucker blade 34. As the primary roll becomes depleted. the counterbalancing ~orce of the roll decreases, cauf.ing the tucker blade 34 to lower until, when the roll is f.ubstantially depleted, the tucker blade engages the toweling 44 and introduces it into the nip, thereby starting the ceverse roll of toweling when the primary roll is subfitantially depleted, as shown in Figure 7, where the tail end 46 and core 48 of the primary roll can be ~een.
A particular advantage of this invention compared to prior art devices is that it i~ much easier to install the reserve roll. In thi6 invention the reserve roll is loaded, the arm 33 of the tucking element is pivoted clear, the ceserve roll sheet material i6 pulled down in place, and the arm is repivoted. In contrast, in prior art devices, such as described in our U.S.
patent 4,378,912, it was necessary to remove the primary roll 5 3~ 2 ~.
~heet material fro~ between the roller~, raise the ~ensing ~eana, fead ehe ~heet material under the ~ensing naan~, and re~hread the sheet material between the rollern. All of the~e ~tepB, whicb were cequired beore the ee~erve coll wa~ loaded i~to the di~pen~er, are not eequiced i~ this invention.
