Definitions

  • This invention relates to apparatus for dispensing paper toweling or other paper sheet material from a roll. More particularly, the dispenser apparatus incorporates an electric motor for facilitating dispensing of the toweling or other paper sheet material.
  • the paper toweling is comprised of individual paper towel segments separated by perforated tear lines, and in others the toweling has no perforated tear lines formed therein, severing or cutting individual sheets from the toweling accomplished by some suitable severing structure incorporated in the dispenser.
  • U.S. Patents Nos. 6,314,850 and 6, 553 879 disclose apparatus for dispensing paper toweling including a rotatable toweling support roller and a cutter blade pivotally mounted on the outer peripheral portion of the roller.
  • the blade is movable between a first position in which the cutting edge of the blade is positioned closely adjacent to the outer peripheral portion and a second position in which the blade is disposed at an angle relative to the outer peripheral portion with the cutting edge of the blade spaced from the toweling support roller.
  • the cutter blade when in the second position projects in a direction generally opposed to the direction of rotation of the toweling support roller. Pulling force exerted on the toweling by a user not only serves to rotate the toweling support roller but also cause the toweling to bear against the cutting edge of the cutter blade to sever the toweling.
  • Electro-mechanical dispensers employing an electric motor to transport toweling and actuate cutter mechanisms are also well known. Such arrangements include both dispensers which are manually actuated, as by means of a push button and those employing a sensor, such as a sensor sensing proximity of a user's hand, to initiate operation.
  • U.S. Patent No. 6,820,785, issued November 23, 2004 discloses an electro-mechanical roll towel dispenser including a housing with a roll carrier disposed therein to rotationally support a roll of towel material.
  • An electromechanical feed mechanism is disposed in the housing to dispense measured sheets of the towel material.
  • the feed mechanism operates in a first mechanical operational mode wherein the towel sheets are dispensed by a user grasping and pulling on a tail of the towel material extending from the housing, and a second electrical operational mode wherein a measured length of a next sheet is automatically fed from the housing to define the tail for the next user.
  • the dispenser of U.S. Patent No. 6,820,785 includes a sensor for detecting a parameter that is changed by an initial pull exerted on a tail of a web of material extending from the opening of the dispenser.
  • the sensor also generates a signal sent from the sensor to a control circuit or circuitry causing the motor employed in the apparatus to drive the feed mechanism until a measured length of web material that includes the tail of web material has been fed from the dispenser in the form of a measured sheet for subsequent removal by the user.
  • U.S. Patent No. 8,082,827 discloses a towel dispenser which incorporates a oneway rotational coupling enabling the dispenser to be operated by motor or in a manual dispensing mode separately from the motor.
  • U.S. Patent No. 7,987,756, issued August 2, 2011 discloses a dispenser for paper toweling which incorporates a cutter blade within an actuator roller carrying paper toweling.
  • a drive motor is activated to drive the actuator roller during the time the cutter blade is extended to cut the paper toweling and deactivated when the cutter blade is retracted.
  • WO 2011/100056 A1 of the inventors of the present application discloses a paper sheet material dispenser according to the preamble of claim 1, i.e. a toweling dispenser in which an electric motor driven toweling support roller and a handle for rotating the toweling support roller are connected by a one-way clutch, which allows the handle to rotate the toweling support roller only in a single direction of rotation when the electric motor does not drive the toweling support roller, the single direction transporting toweling on the toweling support roller to an exit opening of the dispenser.
  • the present invention relates to a paper toweling dispenser apparatus according to claim 1, which is electro-mechanical in nature to provide electric motor assisted dispensing and which is relatively simple, inexpensive and reliable.
  • the apparatus lowers the consumption of electrical energy required for operation, thus prolonging battery life.
  • the apparatus provides consistent tail length externally of the housing thereof for manual grasping and pulling by a user.
  • the motor eliminates the need for toweling support roller return springs, an expedient employed in U.S. Patent No. 6,314,850 , for example, to return the toweling support roller to an initial or rest position wherein a new toweling tail extends from the housing of the apparatus for access by the next user, providing a reduction of required pull force and consequent tabbing.
  • springs must be tensioned during initial rotation of the toweling by manually pulling the toweling. This requires higher pulling forces, increasing the likelihood of tabbing.
  • Activation and deactivation of the electric motor is accomplished by means of a simple switch, thus no circuit board or complicated sensor/control circuitry is required.
  • the paper toweling dispenser apparatus of the present invention includes a roll support for rotatably supporting a roll of paper toweling having a tail and a housing defining an opening.
  • a rotatable toweling support roller is spaced from the roll support for receiving paper toweling from the roll of paper toweling, the toweling support roller having a cylindrically-shaped outer peripheral surface.
  • An electric motor is operatively associated with the toweling support roller for selectively rotating the toweling support roller.
  • the apparatus also includes an electric switch operatively associated with the electric motor and with the toweling support roller.
  • the electric switch is responsive to rotation of the toweling support roller caused by a user of the paper towel dispenser apparatus pulling on the paper toweling tail projecting through the opening and extending outwardly from the housing to a first position to energize the electric motor when the toweling support roller reaches the first position and cause rotation of the rotatable toweling support roller by the electric motor from the first position to a second position.
  • a cutter blade is provided for substantially or completely severing the paper on the toweling support roller during rotation thereof caused solely by the user pulling on the paper toweling tail and without energization and use of the electric motor before the toweling support roller reaches the first position.
  • the electric switch is responsive to rotation of said toweling support roller by the energized electric motor to the second position to de-energize the electric motor and present a new tail projecting through the opening and extending outwardly from the housing.
  • a paper sheet material dispenser apparatus is illustrated, the apparatus for dispensing sheet material in the form of paper toweling from a roll of paper toweling R.
  • the apparatus includes a housing 10 which is suitably positioned in an outer paper towel dispenser cabinet (not shown) and secured thereto by any suitable expedient such as screws or other suitable mechanical fasteners.
  • a roll support is operatively associated with the housing 10 to rotatably support a roll of paper toweling R ( Fig. 4 ) in a conventional fashion Toweling 12 from the roll is shown in Figs. 4 , 5 , 7 , 9 and 11 and identified by reference numeral 12.
  • the disclosed roll support includes two double-ended arms 14, 16 spaced from one another and roll engagement members 18 at the distal or upper ends of the arms for entering the ends of the roll.
  • a rotatable toweling support roller 22 is rotatably mounted within the housing 10 for receiving toweling 12 and supporting and transporting the toweling.
  • the rotatable toweling support roller 22 has a cylindrically-shaped outer peripheral surface and is rotatable in a predetermined direction of rotation when pulling forces are applied to the toweling supported thereby.
  • Stub shafts project from the ends of the toweling support roller and in turn are supported by the housing.
  • a cutter blade 26 is pivotally connected to the toweling support roller.
  • Cutter blade 26 has attached to the ends thereof cam followers 30, each including a cam follower arm 32 and a roller 34.
  • Each roller 34 rides in a channel 36 of a cam 38.
  • Cams 38 are located at both ends of the housing, it being understood that the channels 36 of these cams are directed inwardly.
  • the cutter blade is movable between an inactive position (shown in Fig. 5 ) wherein the cutter will not sever the toweling and a severing position (see Fig. 7 ) wherein the cutting edge of the cutter blade is positioned outwardly of the toweling support roller to at least partially sever the toweling on the toweling support roller, an operation which will be described below.
  • the dispenser apparatus structure described thus far is essentially that disclosed in U.S. Patents Nos. 6,314,850 and 6,553,879 .
  • the cutter blade when in its inactive or first position lies substantially flat against the toweling support roller with the cutting edge positioned closely adjacent to the cylindrically-shaped outer peripheral surface and a severing or second position wherein the cutting edge of the blade is positioned outwardly of the toweling support roller and disposed at an angle relative to the outer peripheral surface thereof.
  • the cutter blade when in the second position projects from the pivot in a direction generally opposed to the direction of rotation of the toweling support roller.
  • an electric motor 40 is operatively associated with the toweling support roller to selectively rotate the toweling support roller.
  • an electric switch 42 is operatively associated with the electric motor and with the toweling support roller.
  • the electric switch is electrically connected to the electric motor, with no control circuit boards intermediate the electric motor and the electric switch.
  • the electric switch 42 is responsive to rotation of the toweling support roller 22 by a user of the paper towel dispenser from a rest or inactive position to a first position to energize the electric motor when the toweling support roller reaches the first position and cause rotation of the toweling support roller by the electric motor from the first position to a second position and reducing the pull force required by a user pulling the paper toweling during rotation of the toweling support roller between the first position and the second position. Further, the electric switch is responsive to rotation of the toweling support roller beyond the second position to de-energize the electric motor. This operation is described in more detail below.
  • Electric switch 42 includes a switch actuator element 44 having a roller 46 at the end thereof which is biased into engagement with a circular end 48 of the toweling support roller 22.
  • the switch actuator element alternatively opens or closes the switch during rotation of the toweling support roller.
  • an arcuate projection 50 Located at circular end 48 of the toweling support roller and engaged by the switch actuator element roller during rotation of the toweling support roller is an arcuate projection 50.
  • the projection extends only part way along the periphery of the toweling support roller and has two tapered projection ends 52.
  • a toweling support roller gear 54 Extending completely about circular end 48 and disposed inwardly of the arcuate projection, is a toweling support roller gear 54 having teeth. Meshing with the teeth of the toweling support roller gear are teeth of a drive gear 56 which is driven by electric motor 40, the latter suitably being in the form of a DC gear motor, A one-way clutch needle bearing 58 connects the drive gear to the electric motor to allow the performance of certain functions indicated below.
  • Electric wiring 60 connects the switch 42 to the electric motor.
  • the electric switch is located between the electric motor and a source of DC power in the form of electric batteries 62 (see Fig. 2 ). In the interest of simplicity, the conventional wiring extending between the switch and the batteries is not illustrated.
  • the batteries are normally covered by a cover plate 64 readily snapped into or out of position as depicted in Figs. 1 and 2 .
  • Figs. 5 through 12 provide an illustration of the operation of the dispenser apparatus, including a dash line illustration in Figs. 5, 7 , 9 and 11 of the location of the blade and follower during consecutive stages in the operation of the apparatus.
  • Figures 4 - 12 is indicated as an embodiment of a dispenser that does not form part of the invention but which is useful for understanding the invention.
  • Figs. 5 and 6 illustrate the condition of the various components when pulling of toweling 12 by a user begins.
  • the toweling tail may be brought to the position illustrated in Fig. 5 by manually rotating the toweling dispenser roller 22 by a rotatable manually engageable element in the form of a handle or knob 68 connected to the toweling support roller.
  • a one-way clutch (not shown) may be employed to ensure that the toweling support roller is being rotated in a direction to advance the toweling.
  • the handle 68 can also be used to advance and dispense the toweling if the batteries fail.
  • the user can pull on the tail as usual when not utilizing the apparatus in motor assisted mode. In this non-motor-driven mode, the required pull force is still relatively low since the gear motor is in effect disengaged from the toweling support roller by employing the one-way clutch needle bearing 58 or some other suitable one-way clutch mechanism.
  • Figs. 9 and 10 show the condition of the structural components when an individual towel has been severed from the toweling and a new tail end is in the process of being presented to the user.
  • severing is accomplished by the user pulling on the tail when the blade is at the angled position represented in Fig. 7 .
  • the motor will continue to rotate the toweling support roller to advance the next tail. This continues until the structural elements reach the condition shown in Figs, 11 and 12 wherein the switch is opened to de-energize the electric motor during or after passage of the rearmost tapered end of the projection 50 past the switch.
  • FIG 3 shows the switch actuator element 44 just prior to passage of the rearmost projection end 52.
  • the tapered projection ends facilitate engagement with the arcuate projection and disengagement there from. After de-energization, the momentum of the toweling support roller will bring it back to its initial inactive or rest position until the newly presented tail is pulled to again begin dispensing.
  • the one-way clutch employed in the drive gear 56 results in the de-energized electric motor not impeding this final movement of the toweling support roller.
  • the toweling dispenser apparatus includes another feature which also reduces likelihood of tabbing.
  • a shock reducing element in the form of a freely rotatable roller 70 mounted for up and down movement within slots formed in opposed sides the housing is located in the path of the paper toweling extending between the toweling support roller and the roll support. If slack exists in the toweling, as illustrated for example in Fig. 5 , pulling and consequent tautening of the toweling will cause the roller 70 to move upwardly as shown in Fig. 7 . This reduces pulling forces at the tail distal end which might otherwise occur as a result from the shock resulting from taking up of the slack during pulling.
  • a curved plate 80 having curved pressure fingers 82 is pivotally attached to housing 10 and is movable between an open position ( Fig. 2 ) and a closed position ( Fig. 1 ). When in the closed position, the fingers are used to exert a downward force on the toweling on toweling support roller 22 to facilitate cutting of the toweling. If complete cutting or severing of a sheet from the toweling is desired without the user pulling on the sheet to tension it against the blade, a finger or fingers may be designed to hold the paper toweling in firm engagement with the surface of the toweling support roller.
  • the lengths of the tails projecting from the dispenser can be changed. Also, actual total sheet length can be changed by employing toweling support rollers of different drum diameters.
  • Figs. 13 - 17 relate to a first embodiment of the invention.
  • a tail is present and projecting from the dispenser which is grasped by the user to begin dispensing, as was the case with the previously described embodiment.
  • the electric motor is not energized until a sheet is substantially or completely severed by the cutter blade. After severing of the sheet, as shown in Fig. 9 , the switch 42 is closed and the tail of the remainder of the paper toweling extends through an opening in the housing of the paper towel dispenser apparatus and extends downward therefrom for grasping by the next user.
  • FIG. 14 - 17 conform to the Figures 9 -12 relating to the embodiment not incorporating the invention and the structural components are the same except for one difference.
  • the projection 50 has been substantially shortened so that it is engaged with the switch to close the switch only for a shorter duration but one sufficient to complete rotation of the rotatable toweling support roller to the position shown in Fig. 11 wherein the new tail projects through the housing opening and extends outwardly from the housing a desired predetermined distance.
  • the life of a battery electrical source employed with the dispenser will be sufficiently prolonged utilizing this approach. Of course disengagement between the switch and the projection at this stage will immediately result in termination of rotation of the toweling support roller.
  • Fig. 18 is a flow chart which illustrates the operation of a second embodiment which is a more advanced version of the first embodiment.
  • a logic control L functions as a motor control structure operatively associated with the electric motor and the electric switch for preventing energization of the electric motor to rotate the toweling support roller if the momentum of the toweling support roller caused by a user's pull has been sufficient to place a new tail so that a predetermined adequate length thereof extends outwardly from the housing.
  • Logic is used to determine if an adequate tail is present. This can be done by incorporating a switch or a sensor in the motor control structure. If an adequate tail is present, the motor does not turn on. If an adequate tail isn't present, the motor will turn on until the drum rotates to a switch point that turns off the motor. In addition to prolonging battery life, a consistent tail length is produced and there is less tabbing than when return springs are utilized for this purpose. Drum return springs add to the amount of pull force required to dispense a sheet of toweling.
