Background

Systems for dispensing consumables are common in many environments today. For example, consumable dispensers (e.g., paper towel dispensers) are used in many private, semi-private, and public restrooms, kitchens, and work areas. In view of this widespread adoption, it is desirable to ensure that the dispenser is easily loaded with product, thereby reducing maintenance overhead/burden, and ensuring smooth operation after the loading process.

Disclosure of Invention

In general, the subject matter of this specification relates to paper product dispensers for roll-type products, such as roll-type hand towels. One aspect of the subject matter described in this specification can be embodied in a system that includes a paper product dispenser comprising: a housing comprising a front, a rear, two sides, a product retention area defined by the front, the rear, the two sides, and a dispenser throat defining an opening through the housing; a support device configured to support a roll product in the product holding zone, wherein the roll product has a tail; a motor operably coupled to the roll-product and configured to rotate the roll-product in at least one of a first direction and a second direction; and a feed mechanism having a first side opening and a second side opening different from the first side opening, wherein both the first side opening and the second side opening are different from the dispenser throat, and wherein the first side opening is configured to receive the tail of the rolled product when the rolled product has a first orientation and rotates in the first direction, and the second side opening is configured to receive the tail of the product when the rolled product has a second orientation and rotates in the second direction. Other embodiments of this aspect include corresponding apparatuses and methods.

Yet another aspect of the subject matter described in this specification can be embodied in a method that includes: rotating a roll product to feed a tail of the roll product into a feed mechanism having a first side opening and a second side opening different from the first side opening, wherein the first side opening is configured to receive the tail of the roll product when the roll product has a first orientation and rotates in the first direction and the second side opening is configured to receive the tail of the product when the roll product has a second orientation and rotates in the second direction. Other embodiments of this aspect include corresponding devices and systems.

Particular embodiments of the subject matter described in this specification can be implemented to realize one or more of the following advantages. Loading a roll of tissue or toilet paper into a corresponding electronic dispenser has traditionally required threading the tail of the roll through a set or series of rollers. Such threading typically requires a service person to push the tail into the roller, then through the roller (e.g., by actuating a dispenser motor) and out through the dispenser throat for use by a user. If the tail does not penetrate uniformly into the roller, the angled tail may tear prematurely when propelled by the motor or cause a jam during dispensing. Further, with such conventional dispensers, other dispensing errors may occur if the roll is loaded back into the dispenser, e.g., when the dispenser is configured to unwind the roll in a clockwise direction, the roll is unwound counterclockwise in the loaded dispenser, and vice versa.

The feed mechanism described herein reduces the likelihood of a pigtail being fed askew into the dispenser because it automates the tail feed process, thereby eliminating service attendant feed errors while saving attendant time because they no longer need to perform this step. Further, the feed mechanism can accommodate rolls loaded for either a clockwise or counterclockwise unwinding configuration, which avoids the problems of conventional dispensers that arise from rolls loaded in a wrong configuration.

The details of one or more implementations of the subject matter described in this specification are set forth in the accompanying drawings and the description below. Other features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.

Detailed Description

The present disclosure relates generally to roll paper product dispensers including an automatic roll (tail) feed mechanism.

In some embodiments, the dispenser includes a feed mechanism biased against the periphery of the mounted roll. The feed mechanism has a first side opening and a second side opening. The first side opening may receive a tail of the roll when the roll is installed and unwound in a first direction (e.g., unwound in a clockwise direction), and the second side opening may receive the tail when the roll is installed and unwound in a second direction (e.g., unwound in a counterclockwise direction).

In operation, after the roll has been installed, the motor in the dispenser will rotate the roll and the feed mechanism will pick up the tail from the periphery of the rotating roll, regardless of whether the roll is rotating clockwise or counterclockwise, and help feed the tail toward the discharge path (e.g., the exit of the dispenser) for use by the user. The dispenser is described in more detail below in conjunction with fig. 1, 2, and 3, with fig. 1 being a representation of an example product dispenser 100, fig. 2 being a representation of an example product dispenser 100 with a roll product 102, and fig. 3 being a side view of a representation of a cross-sectional view of the example dispenser 100.

The dispenser 100 may be, for example, a towel dispenser 100 for rolled paper products 102, such as toilet tissue or wipes. Paper products describe sheet-like materials made from cellulosic fibers (e.g., wood pulp), synthetic fibers (e.g., polypropylene), or some combination thereof, and include, for example, toilet tissue, paper towels, and wipes. The rolled product is a product that is wound around a core 104 or central axis 106 (e.g., the axis of the wound paper product 102).

The dispenser 100 includes a body or housing 108, such as a composite or metal housing, having an exterior surface (e.g., an exterior surface of the body 108). The dispenser 100 also includes a product holding area 110 to hold the roll product 102. As shown in FIG. 1, the dispenser 100 is shown with the front cover 112 of the body 108 open to show the product holding area 110.

The product retention area 110 is a space or cavity within the body 108 in which the product 102 may be positioned for dispensing and may be accessed, for example, by rotating a front cover 112 (only partially shown in the figures) away from a rear cover 114 (e.g., a wall mount portion) via a hinge or the like. In some embodiments, the front cover 112 or a front surface of the front cover 112 may be attached to the rest of the dispenser body 108, for example, by magnetic force (e.g., a magnet on/in the front cover 112), friction, or a mechanical interference fit, such as a detent, or a track or slot, to slide open or close the front cover 112.

The body 108 includes a distributor throat 119 that defines an opening through the body 108. The dispenser throat 119 provides an exit through which the dispensed paper 102a may exit the dispenser 100 for use by a user. In some embodiments, the dispenser throat 119 is positioned near the bottom side of the dispenser 100.

The dispenser 100 includes a support device 123 to support the roll product 102 in the product holding area 110. In some embodiments, the support device 123 includes a first spindle arm 116a (e.g., proximate the front cover 112 when closed) and a second spindle arm 116b (e.g., proximate the back cover 114) in the product holding area 110. In combination, the first and second spindles 116a, 116b serve to hold a roll of paper product (also referred to as a roll) 102 along its periphery, as shown in fig. 3, and rotate to facilitate unwinding of the roll 102 for dispensing to a user. The spindle arms 116a, 116b are positioned between the dispenser sides 118, for example, on arms near or attached to the sides 118. In some embodiments, each spindle arm 116a, 116b includes a roller or other rotating member that rotates (or drives) with the unwinding of the roll 102. In some embodiments, the spindle arms 116a, 116b do not rotate. In this case, for example, the roll product 102 may be rotated into place (held and supported by the spindle arms 116a, 116 b) in response to a user pulling on an exposed portion of the product 102 (e.g., the tail 102 a).

In some embodiments, the spaced relationship of the spindle arms 116a, 116b are substantially parallel to each other in a horizontal plane, e.g., both are in or near the horizontal plane. More generally, however, as used herein, the spaced relationship means that the two spindle arms 116a, 116b are positioned relative to each other to allow the roll 102 to rest on them and not fall off by gravity, and are placed no farther apart than the diameter of the roll 102. In some embodiments, other support devices may additionally or alternatively be used to support and/or hold the roll 102, as described below.

In some embodiments, for example, the support device 123 in place of the spindle arms 116a, 116b includes a core support mechanism (not shown). The core support mechanism may be a spindle (or rod) that extends through the core 104 generally along the central axis 106 and is supported on both the left and right sides of the dispenser 100 (e.g., on brackets secured to the sides 118 of the dispenser 100). In these embodiments, the core support mechanism is removable to allow it to be inserted into the core 104 of the roll 102 and then placed, for example, in a cradle. In these embodiments, either or both of the core support mechanism and the roll 102 may be rotatable.

In some embodiments, the support device 123 includes support arms that extend from either side (e.g., side 118) of the dispenser 100 and engage the core 104 of the roll 102 on each respective side to retain the roll 102 in the product retention area 110. For example, the arms include tabs or other extensions that will be at least partially inserted (e.g., protruding) into the core 104 on either side of the roll 102 to retain it. The arms are semi-rigid such that they can be flexed apart to allow the roll 102 to be placed between the rolls, and then released to "pinch" the roll and rotatably hold the roll 102.

The dispenser 100 includes a motor (not shown). A motor is coupled to the roll product 102 and operates to rotate the roll product 102 in at least one of a first direction (e.g., clockwise) or a second direction (e.g., counterclockwise). The motor may be coupled to the roll 102, for example, by a first shaft arm 116a and a second shaft arm 116b or a core support mechanism (or by a pair of rollers 120, 122, as described below). In such embodiments, the motor turns the spindle arms 116a, 116b (one or both), the core support mechanism, or one or both rollers 120, 122 (e.g., through gears, belts, or another type of transmission or direct coupling) to rotate (e.g., unwind) the roll 102.

In some embodiments, the dispenser 100 includes a proximity sensor (e.g., an IR sensor) that detects user movement, for example, near the front or throat 119 of the dispenser 100 to indicate that the user requests dispensing. For example, upon such detection, the motor actuates the roll 102 and causes a portion of the roll 102 to unwind through the throat 119 and advance to the user.

The dispenser 100 includes a feed mechanism 127. The feed mechanism collects the tail of the roll 102 to properly feed it into the dispenser 102 for dispensing (e.g., as needed when a new roll 102 is inserted into the dispenser 100 or after the dispenser 100 has been serviced and a partially depleted roll 102 needs to be reinserted into the dispenser 100). Generally, the tail 102a of the roll 102 refers to the free end of the roll 102, i.e., the end portion of the roll 102 that is available for unwinding from the remainder of the roll 102.

The feed mechanism 127 has a first side opening 131 and a second side opening 132 different from the first side opening 131, as shown in fig. 4A-4C, which is a side view of a cross-sectional view of the exemplary feed mechanism 127. Both the first side opening 131 and the second side opening 132 are distinct from the distributor throat 119. In some embodiments, for example, the feed mechanism 127 spans the width of the roll 102 and/or dispenser (e.g., from one side of the dispenser body 108 to the other side 118). In other embodiments, the feed mechanism only partially spans the width of the roll 102. The feed mechanism 127 may be supported, for example, by a support structure attached to (i) one or both sides 118, (ii) the interior of the front cover 112, such that when the front cover 112 is closed, the feed mechanism 127 presses against the roll 102 or (ii) the front lower support 121.

Regardless of the particular support system, the feed mechanism 127 is positioned against the periphery of the roll 102 in use. For example, the feed mechanism 127 is positioned to engage the peripheral portion of the roll 102 in a position proximate to: front cover 112, front lower support 121, the bottom or top of roll 102 when closed, or a portion of roll 102 proximate to back cover 114.

In operation, the first side opening 131 receives the tail 102a of the roll product 102 when the roll product 102 has a first orientation and is rotated in a first direction. For example, the first side opening 131 receives the tail 102a when the roll 102 is unrolled in a clockwise direction (i.e., a first direction when in a first orientation). And the second side opening 132 receives the tail 102a of the roll product 102 when the roll product 102 has a second orientation and is rotated in a second direction. For example, the second side opening 132 receives the tail 102a when the roll 102 is unwound in a counterclockwise direction (i.e., a second direction when in the second direction). The particular orientation of the roll 102 is set by the design of a given dispenser 102, but in either orientation and unwinding direction, the feed mechanism 127 can grasp the tail 102a as the roll 102 rotates (e.g., via actuation of a motor). Generally, the roll orientation is such that the tail 102a points in the direction of the roll 102 rotation/direction.

To facilitate guiding the tail 102a into one of the first side opening 131 or the second side opening 132 as the roll 102 rotates, in some embodiments, the feed mechanism 127 includes a feed head 135 slidably attached to a feed mechanism body 137, as shown in fig. 5, which is a representative expanded view of a cross-sectional view of the exemplary feed mechanism 127. In some embodiments, the feed head 135 is movably attached to the feed mechanism body 137 by a biasing device 136 (such as, for example, a spring 136) to bias the feed head 135 against the surface perimeter of the roll 102. The feed mechanism body 137 is fixed relative to the feed head 135. Thus, when the tail 102a encounters the feed head 136, the tail 102a is picked up from the surface of the roll 102 and directed into the appropriate first side opening 131 or second side opening 132. For example, fig. 4B shows the tail portion 102a guided into the first side opening 131, and fig. 4C shows the tail portion 102a guided into the second side opening 132. First, the tail 102a is pushed into and at least partially through the appropriate opening 131, 132 by the force from the rotating roll 102.

In some embodiments, the feed mechanism 127 includes a feed puller 150, such as an electromechanical device, having two opposing feed rollers 150a, 150 b. The opposing feed rollers 150a, 150b rotate in unison (e.g., by pinching the tail 102a between the feed rollers 150a, 150b) to pull the tail 120a through the appropriate first side opening 131 or second side opening 132. More specifically, the rotational force of the roll 102 pushes the tail 102a to the opposing feed rollers 150a, 150b, and then the opposing feed rollers 150a, 150b provide a force (or additional force) to direct the tail along the discharge path to the throat 119. The opposing feed rollers 150a, 150b can be actuated, for example, in conjunction with a motor, such that when (e.g., and as long as) the motor actuates the opposing feed rollers 150a, 150b, the feed rollers are also actuated (e.g., rotated). This actuation rotates the feed roller 150a in the counterclockwise direction and the feed roller 150b in the clockwise direction.

To prevent the tail 102a from bunching in the openings 131, 132, for example, the feed puller 150 (e.g., opposing feed rollers 150a, 150b) rotates at a first rate, the motor rotates the roll product 102 at a second rate, and the first rate is greater than the second rate. For example, the rate at which the paper 102 is pulled by the opposing feed rollers 150a, 150b (e.g., length per unit time) is five percent (or ten) faster than the rate of the rolled product 102 being unwound by the motor (e.g., length per unit time). For example, the roll 102 may rotate at a rate of 1.0 inch/second, and the feed mechanism 127 rotates the feed rollers 150a, 150b at a rate of 1.1 inch/second. This differential speed helps to alleviate any bunching and jamming problems with the feed mechanism 127. More generally, the differential speed selected may depend on a number of factors, including the strength of the paper product of the roll 102. The differential speed may be selected to overdrive the opposing feed rollers 150a, 150b as compared to the roll 102 so that the opposing feed rollers 150a, 150b apply tension on the paper product of the roll 102 while not providing such a large strain to break or prematurely tear the paper product. In some embodiments, a separate motor is used to actuate the feed puller 150 and rotate the roll 102. In other embodiments, the same motor may be used to actuate the feed puller 150 and rotate the roll 102.

In some embodiments, in addition to or in lieu of the slidable feed head 135, the dispenser 100 includes a track 155 along which the feed mechanism 127 can slide and/or pivot, as shown in fig. 6, which is a side view representation of a cross-sectional view of another exemplary feed mechanism 127. For example, the feed mechanism 127 can slide back and forth along a track 155 parallel to the axis 156.

In some embodiments, the feed mechanism 127 is biased against the perimeter of the roll 102 as the diameter of the roll decreases during consumption of the roll 102. For example, the feed mechanism 127 is biased along the track 155 by a biasing member (e.g., spring) 157 to keep the feed mechanism 127 pushed upward against the roll 102 as the diameter of the roll shrinks as the roll 102 is depleted. This allows the feed mechanism 127 to be always positioned to pick up a tail 120a of a different size (e.g., diameter roll 102), and conversely, when a new roll 102 is inserted, the feed mechanism 127 can slide back toward the end 161 to accommodate a new (or different) larger diameter roll (as compared to a depleted roll). Further, the track 155 including the feed mechanism 127 can pivot along an arc 158 (about point 163). In some embodiments, the weight of the head 165 of the track 155 (or another biasing member) biases the track 155 to pivot toward (and against) the roll 102. In this manner, the adjustment available through pivot 163 and track 155 facilitates feed mechanism 127 engaging roll 102 regardless of whether the diameter of roll 102 is large or small.

In some embodiments, feed mechanism 127 includes additional rollers 700a and 700b coupled to rollers 150a and 150b, respectively, by flexible connectors such as straps 702a, 702b (or the like), as shown in fig. 7, which is a side view of a representation of a cross-sectional view of yet another exemplary feed mechanism 127. For example, the straps 702a, 702b may have opposing grooves to better grip the tail 102a and pull it through or the straps 702a, 702b may be smooth, relying on pressure and/or other friction or adhesive to grip the tail 102 a. Using the elongate belt system of fig. 7 may reduce tearing of the roll paper including the tail 102a because the feed mechanism 127 has more surface area available for grasping than the feed mechanism 127 shown in, for example, fig. 4A-4C.

In some embodiments, the dispenser 100 includes a pair of rollers 120, 122. The roller pairs 120, 122, like the spindle arms 116a, 116b, may extend across the width of the dispenser 100 and rotate. The roller pairs 120, 122 are used to receive paper from the feed mechanism 127 and direct it downward through the dispenser throat 119 and out to the user. For example, when paper is fed between the roller pair 120, 122, the roller 120 rotates clockwise and the roller 122 rotates counterclockwise. In this manner, the roller pairs 120, 122 draw/pull or guide the paper from the roll 102 and dispense it down to the dispenser throat 119.
