Abstract

A paper toweling dispenser apparatus including damping structure for taking up over- spin slack, including a pivoting paper guide pivotally connected to a fixed paper guide by springs which operate in sequential stages during paper toweling dispensing.

Description

PAPER TOWEL DISPENSER DAMPING SYSTEM
TECHNICAL FIELD
This invention relates to dispenser apparatus for dispensing paper toweling and more particularly to structure for damping forces applied to a roll of toweling when overspin slack is taken up. The term "paper toweling" as employed herein also encompasses tissue and the teachings of this invention are applicable to dispensing from rolls of paper tissue.
BACKGROUND OF THE INVENTION
The present invention addresses certain problems, including the problem of "tabbing" occurring during use of a paper towel dispenser. Tabbing occurs when a piece of towel tears off the sheet when a user grasps and pulls the paper. Tabbing may occur with one or two hand pulls. Papers that absorb water at the greatest rate are most likely to tab. The rate of water absorbency varies by paper manufacturer and grade . Premium grade papers tend to absorb water the quickest and are generally harder to cut which leads to a higher rate of tabbing.
It has been found that tabbing occurs when overspin slack is taken up and/or when a blade on the dispenser is utilized to cut the paper. A "shock" is present at the moment the overspin slack is exhausted. The shock occurs because the stationary roll towel must begin rotating at the moment that the overspin slack is exhausted. The shock is greatest with full rolls and diminishes as the roll is exhausted. U.S. Patent No. 7,500,420, issued March 10, 2009 discloses an approach for addressing the "tabbing" problem.
Another potential problem is the accumulation of toweling wrinkles caused by overspin which can interfere with cutting of the toweling.
DISCLOSURE OF INVENTION
The present invention deals with the problems of "tabbing" and toweling wrinkling, as well as reducing the chance of toweling accumulating on a toweling support roller during dispensing. The invention is characterized by its simplicity, reliability and effectiveness of operation. In the invention, a damping nip roller is rotatably mounted on a pivoting paper guide of a paper guide assembly to dampen shock force that occurs when overspin slack is fully consumed. The paper guide assembly improves cutting by preventing accumulation of toweling wrinkles.
This arrangement also creates nearly 270 degrees of wrap on the toweling support roller which further improves the ability to cut a variety of toweling types by reducing chance for toweling to slip on the toweling support roller.
A two stage spring action is incorporated in the apparatus - coil springs and plastic springs. After initial damping begins, plastic springs that are integrated into the pivoting paper guide engage a fixed mechanism feature to apply additional spring force and increase damping.
Other features, advantages and objects of the present invention will become apparent with reference to the following description and accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION
Referring now to the drawings, a rear housing portion of a paper toweling dispenser incorporating the teachings of the present invention is illustrated, the housing portion being designated by reference numeral 10. As is conventional, the dispenser incorporates two support arms 12 which are used to rotatably support a roll of paper toweling to be dispensed. Fig. 7 illustrates a paper toweling roll 14.
As is also conventional, the illustrated toweling dispenser includes a toweling support roller 20 which rotates during the dispensing operation and the toweling exits a dispensing opening 22. In the arrangement illustrated a retractable cutter blade 24 is operatively associated with the toweling support roller similar to the arrangement disclosed in above-referenced U.S. Patent No. 7,500,420.
Incorporated in the dispenser is a damping assembly which includes a damping nip roller 32 and a pivoting paper guide 34. The damping nip roller 32 is rotatably supported at the distal or outer end of the pivoting paper guide.
As perhaps may best be seen with reference to Fig. 9, ribs 36 are located on the curved underside of the pivoting paper guide. Pivot pins 44 pivotally attach the pivoting paper guide 34 to side panels of the housing portion 10, the pivot pins positioned at the distal end portions of elongated members or arms 42 of the pivoting paper guide.
Stub shafts 40 are attached to ends of coiled springs 46, the other ends of the springs 46 being connected to the housing portion 10. The springs 46 exert a downward force on the arms 42 and the pivoting paper guide 34 is biased so that the damping nip roller 32 engages paper toweling support roller 20 when no paper toweling is disposed therebetween. This is the condition shown in Figs. 1 and 3 for example. When however a tensional force is exerted on the toweling between the damping nip roller and toweling support roller sufficient tension in the toweling will pivot the pivoting paper guide and raise the damping nip roller upwardly as shown in Figs. 4 and 7, for example, so that it provides a damping action with respect to the paper toweling.
An inventive feature of this invention relates to the use of flexible plastic springs incorporated in the pivoting paper guide 34 to engage a fixed mechanism feature to apply additional spring force to the pivoting paper guide. Fig. 7 illustrates by means of an arrow the distal ends of the plastic springs 54 which in this embodiment are extensions of some of the ribs 36.
The distal ends of the plastic springs 54 are positioned in recesses 56 which are defined by a fixed paper guide 58. Fixed paper guide 58 is a component of the damping assembly of this invention, along with the damping nip roller 32 and pivoting paper guide 34. Fixed paper guide 58 is attached to the housing side panels. The pivoting paper guide isn't directly connected to the fixed paper guide until the plastic springs contact the fixed paper guide during the damping phase.
Figs. 2 and 4 illustrate the condition of the structural features of the damping assembly in the relative positions assumed thereby with respect to the toweling support roller at maximum damping when the plastic springs 54 are being flexed due to engagement with the fixed paper guide 58 at the location of recesses 42. Engagement is at an upper portion of the fixed paper guide defining the recesses 56. The damping nip roller integrated into the pivoting paper guide 34 will dampen shock force that occurs when overspin slack is fully consumed. The integrated pivoting paper guide 34 and fixed paper guide 58 improve blade cutting by preventing accumulation of toweling wrinkles. This arrangement also creates nearly 270 degrees of wrap on the toweling support roller between nip roller 32 and a second nip roller adjacent to the inner end of the fixed paper guide 58 which further improves the ability to cut a variety of toweling types by reducing the chance for toweling slippage on the toweling support roller. A two stage spring action is incorporated by the use of coil springs and plastic springs and after initial damping begins plastic springs that are integrated into the pivoting paper guide engage a fixed mechanism (the lead end of the fixed paper guide) to apply additional spring force to the damping assembly as discussed above .
