The present disclosure generally relates to apparatus and methods useful in retail checkstands, inventory and warehousing, and other applications that involve processing of a plurality of items. More particularly, the present invention provides a diverter arm of a design that is configured to more effectively direct the movement of items along a retail checkstand, and checkout systems and methods incorporating such a diverter arm.
Many retail stores, such as supermarkets, use checkstands that comprise various components configured to identify items in a customer's order, process coupons, accept payment, hold items while a customer's order is being processed, and/or perform other tasks to complete a customer's order. Most checkstands known in the art today comprise one or more computer terminals and/or scanning devices that are able to identify and/or record each item being purchased by a customer, for example, by optically scanning product identification codes (e.g., bar codes) affixed to each items. Once an item has been scanned or identified, in many instances, the item may be placed on a conveyor (e.g., a conveyor belt) that transports the item to another collection area where the items can be bagged and/or held until the customer is ready to remove them before leaving the store. Examples of checkstands that include scanning devices and conveyors that may be utilized in this manner are disclosed in, for example, U.S. Pat. No. 6,491,218 to Nguyen and U.S. Patent Application Publication 2009/0090583 A1 by Bonner, et al.
In some instances, it may be desirable to use a particular computer terminal or scanning device at a checkstand to identify and/or record items in a customer's order before the previous customer's items have been bagged or removed by the customer, for example, during periods of high customer volume, in stores having a limited number of checkstands, and/or in a number of other circumstances. However, if items purchased by one customer are scanned and placed on the conveyor while a previous customer's items are still being held in the collection area at the end of that conveyor, those new items coming into the collection area may become intermingled with the previous customer's items. This may, among other problems, complicate bagging of each customer's items and/or create confusion when the customers attempt to remove their respectively purchased items from the collection area.
Moreover, if a collection area is full and there is no room for additional items in that collection area, subsequent items placed on the conveyor (whether belonging to that customer or a subsequent customer) may be pushed against items already in the collection area as the conveyor transports them. Soft or fragile items (e.g., bread, eggs, etc.) may be squeezed, broken, or otherwise damaged by the force of other items being pushed against them in these circumstances.
The attendant or user at the checkstand may stop the conveyor in order to prevent items from becoming intermingled and/or damaged as discussed above. However, this may cause a backlog of items on the conveyor, which may, among other problems, require the attendant or user to stop scanning items and/or rearrange items to make room for additional items, thereby reducing the efficiency of the checkout process.
Therefore, what is needed is an apparatus or system for effectively directing the movement of items along one or more conveyors in a retail checkstand without causing damage to certain types of items.
The present disclosure generally relates to apparatus and methods useful in retail checkstands, inventory and warehousing, and other applications that involve processing of a plurality of items. More particularly, the present invention provides a diverter arm of a design that is configured to more effectively direct the movement of items along a retail checkstand, and checkout systems and methods incorporating such a diverter arm.
In one embodiment, the present disclosure provides a diverter arm comprising: an elongated block portion; an upper body portion positioned on top of the block portion substantially along its length, the upper body portion comprising at least a front face; and at least one bristle portion projecting downward from the bottom of the block portion substantially along its length.
In another embodiment, the present disclosure provides a retail checkstand comprising: a conveyor configured to receive items; one or more item collection areas proximate to an end of the conveyor; one or more diverter arms positioned between a portion of the conveyor and one or more of the item collection areas, wherein the diverter arm comprises an elongated block portion, an upper body portion positioned on top of the block portion substantially along its length, the upper body portion comprising at least a front face, and at least one bristle portion projecting downward from the bottom of the block portion substantially along its length.
In another embodiment, the present disclosure provides a method of performing retail checkout comprising: providing a retail checkstand comprising a conveyor configured to receive items; at least first and second item collection areas proximate to an end of the conveyor; one or more diverter arms positioned between a portion of the conveyor and one or more of the item collection areas, wherein the diverter arm comprises an elongated block portion, an upper body portion positioned on top of the block portion substantially along its length, the upper body portion comprising at least a front face, and at least one bristle portion projecting downward from the bottom of the block portion substantially along its length; positioning one or more of the diverter arms in a first position in which items are permitted to pass from the conveyor to a first collection area but not to a second collection area; and positioning one or more of the diverter arms in a second position in which items are permitted to pass from the conveyor to the second collection area but not to the first collection area.
The features and advantages of the present invention will be apparent to those skilled in the art. While numerous changes may be made by those skilled in the art, such changes are within the spirit of the invention.
Some specific example embodiments of the disclosure may be understood by referring, in part, to the following description and the accompanying drawings.
While the present disclosure is susceptible to various modifications and alternative forms, specific example embodiments have been shown in the figures and are herein described in more detail. It should be understood, however, that the description of specific example embodiments is not intended to limit the invention to the particular forms disclosed, but on the contrary, this disclosure is to cover all modifications and equivalents as illustrated, in part, by the appended claims.
The present disclosure generally relates to apparatus and methods useful in retail checkstands, inventory and warehousing, and other applications that involve processing of a plurality of items. More particularly, the present invention provides a diverter arm of a design that is configured to more effectively direct the movement of items along a retail checkstand, and checkout systems and methods incorporating such a diverter arm.
More particularly, the present disclosure provides a diverter arm comprising at least an elongated block portion, an upper body portion positioned on top of the block portion substantially along its length, and at least one bristle portion projecting downward from the bottom of the block portion substantially along its length. In some embodiments, the diverter arm may be placed in one or more positions in order to selectively direct retail items to one of a plurality of collection areas adjacent to a conveyor. The design of the diverter arm of the present invention may, among other benefits, allow the diverter arm to more effectively direct the movement of retail items of different shapes and sizes from a conveyor to a collection area without causing the items to be squeezed, damaged, or caught in the diverter arm or other components of the checkstand. In some embodiments, the upper body portion, block portion, bristle portion, and/or other components of the diverter arm of the present invention may be individual parts that are detachably attached to each other, which may, among other benefits, facilitate repair, replacement, and/or cleaning of certain components of the diverter arm.
It should be appreciated that the diverter arms, checkout systems, and methods of the present invention disclosed herein may be used in conjunction with any checkstand of any configuration that includes at least one conveyor and one or more collection areas, including but not limited to conventional checkstands known in the art. Examples of such checkstands include attendant-operated checkstands, customer-operated checkstands (i.e., “self-checkout” systems), checkstands incorporating “tunnel scanners”, and the like.
In one embodiment, the present disclosure provides a retail checkstand for use for use in a retail store, such as a supermarket, that includes at least one diverter arm of the present invention. While there are various known and suitable checkstand configurations, a particularly suitable configuration for a checkstand of the present disclosure generally comprises a multi-item identification device (e.g., a multi-item scanner), one or more conveyors, and one or more collection areas located at the end of at least one of the conveyors. Retail checkstands of the present invention also may comprise one or more computer terminals, one or more theft mitigation devices, as well as other components commonly associated with checkstands and checkout systems. An example of one configuration for a suitable checkstand 10 is depicted in

The checkstand 10 shown in
Diverter arms 26 and 27 are located near the end of transition conveyor 25 adjacent to the outtake conveyors 28 and 29. In this embodiment, diverter arms 26 and 27 may be positioned to selectively allow items on transition conveyor 25 to pass to only one of outtake conveyor 29 (when in the positions shown in
As a person of skill in the art will recognize, the methods and systems of the present disclosure could be practiced with checkstands having only a single outtake conveyor and/or collection area, or with checkstands having more than two collection areas. In those embodiments, the checkstand may comprise a different number and/or configuration of diverter arms than those shown in
In one embodiment, a first customer may itemize his order using the multi-item scanner 30 and his items can be moved onto outtake conveyor 29 and collection area 41 for bagging while the first customer's order is processed and completed and/or his items are bagged. During that time, a second customer may bring items that they desire to purchase to the same checkstand 10. Diverter arms 26 and 27 may be re-positioned (either manually or using an automated system) at the end of outtake conveyor 29 near transition conveyor 25 to prevent the second customer's items from passing to outtake conveyor 29 and instead allow those items to pass onto outtake conveyor 28 and collection area 40. This arrangement may increase the speed and/or efficiency of the checkout process, reduce inadvertent intermingling of items from different customers' orders, reduce the amount of space and/or equipment reserved for checkstands at a retail store, and/or provide other benefits.
In other embodiments, one or more diverter arms of the present invention may be used to direct the movement of items to different collection areas for other reasons. For example, the diverter arm may be positioned either manually or using an automated system to direct certain types of items (e.g., refrigerated or frozen items, raw meats, fresh produce, etc.) to one collection area, and re-positioned to direct other types of items to another collection area associated with the checkstand. This may be accomplished by moving the diverter arms manually or automatically (e.g., in response to the identification of certain types of items by a scanning device). This may, among other benefits, reduce cross-contamination of certain types items and/or facilitate the bagging of items with similar types of items (which may be more convenient for the customer in transporting and/or storing items).
An example of a diverter arm 200 according to the present invention is shown in
A diverter arm according to the present invention is generally an elongated structure. In many embodiments, the length of the diverter arm is greater than its width and/or height, although the exact dimensions may vary depending on the particular application and/or checkstand in which the diverter arm is used. For example, the length of the diverter arm may be at least as wide as the conveyor(s) across which the diverter arm is designed to extend. In some embodiments, the diverter arm of the present invention may be approximately 3 feet long. In checkstands of the present invention where more than one diverter arm is used, the diverter arms may have the same or different lengths.
One or more bristle portions may be attached to the bottom of the block portion projecting downwardly in any configuration using any means known in the art. The bristles may be made of any suitable material known in the art, such as nylon or other synthetic materials. In some embodiments, the fibers of the bristle may be attached to a solid bristle base having a shape and/or comprising a material that may be easily mounted to the block portion of the diverter arm. For example, the bristle base may be constructed of plastic or a semi-rigid rubber. Referring back to

The upper body portion 210 includes a proximal face 211 and a distal face 212 at the proximal and distal ends 201 and 202 of the diverter arm 200, respectively, as well as a front face 213, a rear face 214, a top face 215, and a bottom face 216. In typical use of the diverter arms of the present invention, items passing along the conveyor will most often contact the front and/or rear faces 213 and 214 of the upper body portion 210. Thus, the upper body portion 210 (and specifically the front and rear faces 213 and 214) may have a shape designed to balance the impact of items on the diverter arm, effectively direct movement of items of different shapes and sizes, and reduce the impact of the diverter arm on soft or fragile items that may be squeezed or damaged. In the embodiment shown in
