9604811
The present disclosure relates generally to the field of paper dispensers, and more particularly to automatic paper dispensers for dispensing discrete paper products therefrom.
Paper dispensers, such as paper towel or napkin dispensers, are generally configured to allow an end user to retrieve paper products therefrom. Conventional discrete paper products dispensers enable users to obtain an unlimited number of paper products with no control mechanism. For example, quick service restaurants employ manual napkin dispensers from which end users may take an unlimited number of napkins. As such, excessive paper product distribution and waste may occur, leading to increased operating expensive.
Moreover, conventional discrete product dispensers are incapable of monitoring product usage and collecting and storing data associated with product dispensing. It would be desirable for product dispensers to be able to monitor usage trends to increase understanding of usage rates, so that dispensers can be adjusted to deliver products efficiently according to observed user needs.
Accordingly, there is a need for improved paper product dispensers that allow for economical and efficient dispensing of discrete paper products.
In one aspect, a sheet product dispenser is provided, including: (i) a loading station for loading sheet material; (ii) a sheet feeding mechanism configured to feed the sheet material; (iii) a presentation station for presenting one or more of the discrete sheet products to an end user; (iv) a sensor downstream of the sheet feeding mechanism and upstream of the presentation station, the sensor being configured to detect a presence of the discrete sheet products; and (v) a controller configured to facilitate dispensing of the one or more discrete sheet products to the presentation station in response to a signal, the controller also being configured to receive and store data, wherein the data includes: a number of requested discrete sheet products associated with the signal, a number of discrete sheet products detected by the sensor, a time at which the one or more discrete sheet products are detected by the sensor, a time at which the signal is received by the controller, an amount of time between the signal being received by the controller and the one or more discrete sheet products being detected by the sensor, or a combination thereof.
In another aspect, a method of dispensing sheet products is provided, including: (i) feeding a sheet material via a sheet feeding mechanism; (ii) dispensing one or more discrete sheet products to an end user at a presentation station, in response to a signal received by a controller; (iii) detecting a presence of the discrete sheet products via a sensor downstream of the sheet feeding mechanism and upstream of the presentation station; and (iv) collecting and storing data including: a number of requested discrete sheet products associated with the signal, a number of discrete sheet products detected by the sensor, a time at which the one or more discrete sheet products are detected by the sensor, a time at which the signal is received by the controller, an amount of time between the signal being received by the controller and the one or more discrete sheet products being detected by the sensor, or a combination thereof.
In yet another aspect, a system for dispensing sheet products is provided, including at least one memory that stores computer-executable instructions, and at least one controller configured to access the at least one memory, wherein the at least one controller is configured to execute the computer-executable instructions to: (i) receive, from an interface, a signal indicative of a request for a number of discrete sheet products to be dispensed to an end user at a presentation station; (ii) direct, in response to receipt of the signal, the feeding of a sheet material via a sheet feeding mechanism; (iii) receive, from a sensor downstream of the sheet feeding mechanism and upstream of the presentation station, a detection indicator indicative of detection of a presence of a discrete sheet product by the sensor; (iv) determine data including: a number of requested discrete sheet products associated with the signal, a number of discrete sheet products detected by the sensor, a time at which one or more discrete sheet products are detected by the sensor, a time at which the signal is received by the at least one controller, an amount of time between the signal being received by the at least one controller and the one or more discrete sheet products being detected by the sensor, or a combination thereof and (v) direct the storage, in one or more data stores, of at least a portion of the data.

Referring now to the drawings, which are meant to be exemplary and not limiting, and wherein like elements are numbered alike:
Disclosed herein are dispensers and methods for automatically dispensing paper products and determining and storing data associated therewith. These dispensers meet one or more of the above-described needs by providing economical and efficient dispensing of discrete paper products, as well as collection and monitoring of user and dispenser usage data. As used herein, the term “discrete paper products” refers to separated material products, such as individual napkins, paper towels, and the like. Discrete paper products are distinguishable from a continuous roll or web of sheet material. As used herein, the term “continuous roll of sheet material” or “roll of sheet material” refers to a web of sheet material that is provided in a continuous form, such as in a rolled form, for dispensing. The continuous roll of sheet material may include perforations in the sheet material at given intervals.
As used herein, the term “sheet material” may refer to any type of natural and/or synthetic cloth or paper material, including woven and non-woven materials. That is, as used herein, the term “paper products” is intended to cover paper, cloth, cloth-like, or other materials that may be used to form discrete products, such as napkins, towels, or food wrappers. The discrete paper products produced by the dispensers and methods disclosed herein may include a fold in the sheet material. For example, the discrete paper products may be folded napkin or folded towel products. The fold may be a hard fold with a crease therein, or a loose fold with a “U” or “C”-shaped configuration. Multiple folds may also be created in a single discrete sheet product, such as a “Z”-shaped fold or dinner napkin fold.
Embodiments of dispensers and methods are described in detail below, with reference to the drawings, wherein like elements are numbered alike.
Dispensers
As shown in
In certain embodiments, the stations and mechanisms may be enclosed in whole or in part within an outer dispenser housing or shell. The outer housing may be made of a substantially rigid material.
In embodiments, as shown in
In embodiments, the dispenser also includes a sheet feeding, or transfer, mechanism configured to feed the sheet material from the roll. The sheet feeding mechanism includes feed rollers 150. In other embodiments, the transfer mechanism includes a multi-roller mechanism having two or more rollers. The rollers may be spring loaded and/or motor driven. The sheet feeding mechanism is configured to accept the tail of a roll of sheet material and feed the material further into the dispenser. As shown in
As shown in
In embodiments, as shown in
The dispenser may include a sheet product conveying mechanism configured to convey the discrete sheet products to the presentation station. In one embodiment, as shown in
In certain embodiments, the dispenser also includes a separation mechanism for separating discrete sheet products from the continuous roll or web of sheet material. For example, the separate mechanism may include a cutting mechanism, such as a cutter or knife assembly, or a speed differential separation mechanism, such as a multi-roller feed mechanism with a reserve drive conveying mechanism. In one embodiment, as shown in
In embodiments, as shown in
In embodiments, the dispenser also includes one or more controllers configured to facilitate dispensing of one or more discrete sheet products to the presentation station in response to a signal. The controller may generally provide logic and control functionality for operation of the dispenser. For example, the controller may be operably connected to one or more motors that are configured to drive the feeding and dispensing mechanisms of the dispenser. The controller may be a suitable electronic device capable of receiving and storing data and instructions. For example, the controller may store data to in any suitable format, such as in an ASCII “.txt” file in a Comma Separated Value (CSV) or text line-item format. In one embodiment, the controller will generate the data file if one does not already exist. In one embodiment, the controller will preserve the existing data and append any new data collected to the existing data.
In embodiments, the dispenser is configured to collect and process a variety of data, including usage, fault, and system performance information. For example, the data may be received and stored by the controller. In certain embodiments, the data includes: the number of requested discrete sheet products associated with the signal, the number of discrete sheet products detected by the sensor, the time at which the discrete sheet products are detected by the sensor, the time at which the signal is received by the controller, the amount of time between the signal being received by the controller and the discrete sheet products being detected by the sensor, or any combination thereof. Advantageously, the collection of this data allows the dispenser to self-verify that the number of paper products dispensed meets the requested number of paper products associated with the signal.
For example, the data may include the actual time of day that paper products are requested and/or dispensed, which would allow the restaurant to track usage rates at meal times. The data may also include: the number of products dispensed per day or hour, the number of products dispensed between dispenser battery charges, the number of product requests received per day or hour, the average time per product dispense, the number of times a loading door is opened per day, the number of dispenser jams per day or hour. Certain data may be collected by additional sensors located within the dispenser. For example, a static electricity sensor may monitor the voltage at the shaft of the first feed roller.
In embodiments, as shown in
In one embodiment, as shown in
Although three buttons 350 for two, four, and six paper products are shown, any number of paper products may be associated with any number or orientation of the buttons 350. Each button may be programmed with a predetermined number of sheet products to dispense. In one embodiment, a selecting switch is provided inside the dispenser to allow an operator to set the predetermined number of paper products associated with each button. The controller may record data associated with which button was pressed and the time at which the button was pressed. In a quick service restaurant setting, for example, a dispenser having a button-based user interface may be located behind the counter for use by an operator at a drive thru, allowing the operator to select a desired number of paper products for a given order.
In one embodiment, as shown in
The dispenser 360 may be set to dispense a predetermined number of paper products for each wave of the end user's hand about the sensor 370. The dispenser 360 may dispense the paper products into the presentation tray or directly into the end user's hand. For example, an internal rotary switch or dial may be configured to be set to the predetermined number of discrete sheet products to be dispensed in response to the signal. The controller may record data associated with which dial/switch position is selected and the time at which the sensor is activated. In a quick service restaurant setting, for example, a dispenser having a sensor-based used interface may be located at a self-serve area for patrons.
In one embodiment, as shown in
In another embodiment, the signal may be triggered by a cash register. For example, a dispense may be initiated by a signal in response to an order being completed at a cash register. In certain embodiments, the data includes sales, usage, or other data associated with the cash register. Certain integrated dispenser and business machine embodiments and features are disclosed in the U.S. Pat. No. 6,704,616, issued Mar. 9, 2004, which is incorporated herein by reference in its entirety.
In certain embodiments, as shown in
In one embodiment, the controller is configured to compare the number of requested discrete sheet products associated with the signal and the number of discrete sheet products detected by the sensor, and turn off the motor when the number of discrete sheet products detected by the sensor matches the number of requested discrete sheet products associated with the signal.
Generally, the dispensers described herein are configured to record the number of requested sheet products, and recognize when the correct number of sheet products has been dispensed, by counting them with a sensor mounted inside the dispenser as they proceed serially through the conveying mechanism. In certain embodiments, when the correct number of products has been dispensed and the motors which drive the rollers stop, the device reads and records the current time. The current time, the number of products dispensed, and the amount of time required to perform the dispense, among other data, may be recorded to the aforementioned data store, or “.txt” file.
In certain embodiments, the dispenser includes a folding station for providing a fold or crease in the discrete paper products. The folding station advantageously allows the dispenser to be loaded with a roll of sheet product, which is more economical and may occupy less volume than discrete folded sheet products themselves, and to also dispense discrete folded sheet products to the end user. The folding station may include a buckle fold mechanism, a slot fold mechanism, a reverse fold mechanism, a tucker fold mechanism, or any other suitable fold mechanism.
The folding station may be configured to fold the discrete sheet products prior to presentation. In one embodiment, as shown in
In use, the roll 110 may be dropped into the outer shell 210 via the loading door 220 along the slots 250 of the slot mechanism 245. The tail of the roll 110 may be placed over the first pair of pinch rollers 280. The tucker finger 260 on the loading door 220 may push the tail between the first pair of pinch rollers 280 to load the tail 125 therein when the loading door 220 is shut. The buckle fold mechanism 270 creates a fold by driving the tail into the buckle tray 300. Once the tail hits the end of the buckle tray 300, the second pair of pinch rollers 290 drives the fold 135 therethrough. The perforation 235 of the sheet material may be separated based upon a speed differential between the first and the second pair of the pinch rollers 280, 290. The speed differential may be about two to one to separate the perforation 235 between the pinch rollers 280, 290. Once the perforation 235 is separated, the discrete sheet product may drop along the dispense shelf 310 into the presentation tray 330. Specifically, the number of discrete sheet products as indicated by the push buttons 350 may drop into the presentation tray 330. The discrete sheet products may be removed as a group by the end user.
In one embodiment, a folded napkin dispenser includes: a loading station for loading a roll of sheet material; a pair of feed rollers configured to feed the sheet material from the roll; a separation mechanism for separating discrete sheet products from the sheet material; a folding station configured to fold the discrete sheet products into folded napkins, which includes: a pair of pinch rollers downstream of the pair of feed rollers and configured to convey the folded napkins to a presentation station and a buckle chamber adjacent to the pair of pinch rollers, wherein a portion of the sheet material enters the buckle chamber and a fold of the sheet material is forced through the pair of pinch rollers; an infrared sensor configured to detect a presence of the discrete sheet products in the buckle chamber; and a controller configured to facilitate dispensing of one or more folded napkins to the presentation station in response to a signal, the controller also being configured to receive and store data, wherein the data includes: a number of requested folded napkins associated with the signal, a number of discrete sheet products detected by the sensor, a time at which the one or more discrete sheet products are detected by the sensor, a time at which the signal is received by the controller, and/or an amount of time between the signal being received by the controller and the one or more discrete sheet products being detected by the sensor.
