## Title
Self checkout stands

## Abstract

A self-check-out stand has a flat belt on which items that have been scanned can be placed. This belt abuts a declining belt, with both belts preferably having abutting ends with upper corners in which a fixed non-rotating nose rod is located with the rod extending across the width of the belt, the rods hold the abutting ends tightly together with only a small crack between the belts. The check-out stand has two sets of unpowered transition rollers to turn the items at an obtuse angle to the conveyer belts. The stand has a declining set of rollers to bring the items to the proper height for the customer to bag. The accumulation area rises from front to back to slow the items being conveyed. A scanner module with a monitor and pay station can be placed at the front end of the stand.

## Background
This application claims priority to Provisional Application Ser. No. 61/295,220 filed on Jan. 15, 2010. which is entirely incorporated by reference.


FIELD OF THE INVENTION
This invention relates to a self-checkout stand for use with a scanner module located at the front end of the checkout stand for self-checkout by a customer, including the scanning of the items, paying for the items, and bagging by the customer.
BACKGROUND OF THE INVENTION
Stores, particularly supermarkets, have experienced difficulty in obtaining, training, and keeping checkout clerks. Consequently, there is a great need for a self-checkout system. A single clerk can then monitor and assist on several checkout lanes at the same time. The present checkout stands cannot handle large orders. Some of them can only handle 8 to 10 items. The bagging area of these checkout stands is usually immediately adjacent to the scanner and is not large enough to handle a large order. They also require the customer to bag an item that has been scanned immediately, which is inconvenient to the shopper in the extra steps the shopper must take in the checkout process.

DETAILED DESCRIPTION OF THE INVENTION
This invention discloses a self-checkout stand for use with a scanning module. The customer first scans the items purchased at a scanning module and may pay for them at that time. The customer then places the items on a flat take-away belt. This self-checkout stand has two belts, one of which is a flat take-away belt, and the other is a declining take-away belt which is adjacent to a set of transition rollers and which in turn is adjacent to declining rollers in the bagging area. It may have a turn-table bagging section or the bagging could take place on the declining rollers or in an accumulation area.

This self-checkout stand 10 is for use with a scanning module, in particular the Fujitsu U-Scan Genesis. As shown in FIGS. 1 and 2, a self-checkout stand 10 is placed adjacent to the scanning module 12. In this case, the scanning module 12 is a Fujitsu Genesis U-scan. The self-checkout stand is also compatible with the Fujitsu Next Generation scanning modules. The scanning module 12 has a scanner 22 on which the customer can scan items, with the identification of the item and the price shown on the monitor 24. The item to be purchased is not put on a conveyor belt until after the customer scans the item. The scanning module 12 can also be constructed to weigh the item in order to price it. After scanning, the customer places the item on the first flat take-away belt 14 which moves the item to the second flat take-away belt 17 which moves the item towards the bagging area. These two flat take-away belts could be constructed as a single belt, but two belts are preferred.
One of the problems of abutting conveyor belts is that small items on the belts frequently fall between the crack between the abutting belts. This problem has been solved in this invention by the use of small diameter fixed nose non-rotating bars 48 placed at the top corners where the belts 14, 17 abut each other as shown in FIG. 4B. This enables the crack between the abutting belts to be so small that even a dime can not fall through. This is not only important for change customers sometimes drop on conveyor belts, but also for small loose items, such as screws and cards that drop through the crack and are difficult to retrieve, even by a clerk. It has been found that a small non-rotating nose bar 48 prevents this from occurring as often happens with small idler rollers.
In order to move the items to be bagged by customers to a more convenient lower level, a declining take-away belt 15 can be used. It can be a part of the second flat take-belt as shown in FIGS. 4A and 4B, or can be a separate belt system with it is own power roller. In the case of two belts being used fixed non-rotating nose bars can be used between them at the upper abutting corners as discussed above.
As shown in FIGS. 4A and 4B, a single belt serves the function of the second flat take-away belt 17 and declining take-away belt 15. This simplifies the checkout stand 10 and allows the use of a single power roller 46 for the combination of belts 15 and 17 into a single belt. This arrangement allows the placement of this power roller 46 inside the checkout stand for safety issues. The small idler rollers 40 and 42 help keep the belts tight during operation which results in smoother processing of the items being purchased.
After finishing the scanning of all items, the customer can pay at the scanning module 12, either by cash, credit or debit card.
After an item exits the declining take-away belt 15 it then turns at an obtuse angle 60 in relation to this belt to make it easier for a customer to bag his or her items. Because items placed by a customer on the first flat take-away belt 14 may end up on the right side 56 or left side 58 of the declining take-away belt 15, a mechanism is needed to insure the items make the obtuse turn and do not pile up on the declining take-away belt 15. For items on the left side 58 of the declining take-away belt 15 this is rather straight forward mechanism. These items are simply conveyed onto the non-powered cassette of rollers 18 which are obtuse to the declining take-away belt 15 at an angle such as to permit the customer easy access for placing the items on a turntable 20 or taking out of the accumulation area 50. The cassette of rollers 18 can be a single cassette or two side by side cassettes as shown in FIG. 5. The cassette on the left 62 can accept the items on the left 58 of the checkstand 10 and needs to have rollers with ends 72 that abut the end 70 of the declining belt 15 in order for items to make the transition at an obtuse angle 60. Items on the right 56 of the checkstand will not pile up on the conveyor, but rather will need to make two steps to turn. These items on the right 56 will be conveyed onto the non-powered triangular transition roller cassette 16, which is in line with the conveyor belts. These items will then make the transition to the cassette or cassettes18 which is at an obtuse angle 60 to the checkstand. This mechanism allows the items to be more evenly distributed onto deceleration ramp collection area 50. The items move down the cassette 18 to the cassette assembly or assemblies of non-powered declining rollers 19 parallel to the roller cassette assemblies 18. Cassette assembly 19 speeds the movement items into the deceleration ramp collection area 50. To prevent items from crashing into the rear of the collection area, this area increases in height from front 68 to back 66. Turning the items at an obtuse angle 60 in relation to the check stand 10 and also lowering the items from the level of the conveyor belts permits easy access by the customer in bagging the items. It is not necessary to have a turntable 20 with this checkout stand. The items could simply be taken off of the deceleration ramp collection area 50 and bagged.
This self-checkout stand can have an auxiliary set aside area 26 on which fragile or small items can be placed to prevent them being damaged or lost on the checkout lane. This self-checkout stand has receipt printer shelves 28. The auxiliary set aside area 26 may have a bag rack 30. The electronics of this unit are housed in the electronics compartment 32. This self-checkout stand 10 has storage cabinets 34. The turntable 20 has bag racks 36 and a hook 38 for reusable bags mounted on a pocket for storing paper bags.
This unit self-checkout stand with the scanning module is especially designed for self-checkout by a customer.
The declining takeaway belt 15 and the cassette assemblies of declining rollers 19 bring the items to a level and position that is convenient for the customer to do the necessary bagging. The scanning module 12 is set up so the customer can pay at this module before the groceries are bagged.
It should be realized that the checkstand without the scanning module can be used with another arrangement used for payment. These are especially true if items have RFID tags which can be recorded electronically.
