Description

"Retail checkout"Technical Field

[0001] The present disclosure relates to a retail checkout. In particular examples, retail checkout for supermarkets with a conveyor belt system and scanner system.Background

[0002] Retail checkouts, in particular supermarket checkouts, have conventionally included conveyor belt systems. Further, in the past couple of decades supermarket checkouts have incorporated scanners for scanning the products sought to be purchased in the same axis as the direction of the conveyor. In addition to the scanner, conventional supermarket checkouts also include printing modules for issuing a receipt as well as payment modules for receiving electronic payments from customers.

[0003] Supermarket checkouts may also include a bagging section where goods that have been scanned are sorted and / or placed in shopping bags.

[0004] Conventional retail checkouts are typically set at a fixed height as the checkout includes substantially heavy furnishings such as the conveyor belt, scanner and furniture at the bagging section. Thus, such height of furnishings does not change depending on the height of the user. As there can be a difference in height between users, there will be checkout operators that find it too low and others too high.

[0005] Throughout this specification the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps.

[0006] Any discussion of documents, acts, materials, devices, articles or the like which has been included in the present specification is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present disclosure as it existed before the priority date of each of the appended claims.Summary

[0007] In addition to lack of height adjustment, conventional supermarket checkouts are not able to accommodate checkout operators who are in a wheelchair. Wheelchair users are unable to use a general-purpose checkout due to lack of sufficient space to accommodate the wheelchair. Furthermore, the configuration of components of such checkout may lack ergonomics for such operators to safely and comfortably work.

[0008] The present disclosure provides a retail checkout comprising: a conveyor belt system, a scanner system, a bagging section, and one or more adjustable supports. The conveyor belt system to convey items to a conveyor end. The scanner system is located between the conveyor end and the bagging section and is configured to enable an operator to scan the items. The bagging section is provided to support scanned items and / or bags. This can include supporting a bag for the operator to place scanned items therein. The one or more adjustable supports are configured to support the conveyor belt system, scanner system, and the bagging section. Furthermore, the adjustable supports are selectively adjustable to raise or lower a height of the conveyor belt system, scanner system, and the bagging section. A clearance zone is provided below the scanner system, wherein the clearance zone has a width configured to receive at least a lower leg region of a wheelchair. In some examples the width is at least 60 centimetres. In further examples, the width of the clearance zone is at least 80 centimetres. In some examples, the width of the clearance zone is approximately 84 centimetres.

[0009] The selectively adjustable height advantageously enables people of various heights, including seated people and people in wheelchairs, to easily reach items from the conveyor end, scan items at the scanner system, and place scanned items in the bags. In some examples, this retail checkout enables the user to selective adjust a desired height including: raising the height suitable for a standing operator; or lowering the height suitable for a seated operator.

[0010] It is advantageous to provide an adjustable supermarket checkout with integrated conveyor belt that is able to be used by people of various heights and including people using a wheelchair.

[0011] The clearance zone is configured to receive a lower leg region of a wheelchair or a seated individual to enables a seated operator to comfortably sit closer to the scanner system and assist the operator’s reach.

[0012] In some examples of the retail checkout, the adjustable supports are configurable to provide the clearance zone that has a clearance height from a floor of between 50 centimetres and 100 centimetres.

[0013] In further examples of the retail checkout, the adjustable supports are configurable to provide the clearance height of approximately 68 centimetres. This height may be suitable for an operator in a wheelchair. In some examples, the clearance height is adjustable to elevate to approximately 100 centimetres, which, when combined with a height of the weight scale, can provide a working height of approximately 110 centimetres.

[0014] In some examples of the retail checkout, the one or more adjustable supports comprises: a first support group to support the conveyor belt system; and a second support group to support the bagging section, wherein the clearance zone is located, at least in part, between the first support group and the second support group.

[0015] In some examples, the width of the clearance zone is approximately 84 centimetres.

[0016] In some examples of the retail checkout, the scanner system includes a first working surface, wherein the first working surface is substantially planar and horizontal, and wherein the one or more adjustable supports are configurable to provide a working height of the first working surface of between 60 to 120 centimetres from a floor.

[0017] In some examples of the retail checkout, the adjustable supports are selectively adjustable to provide at least:a lowered configuration where the working height is approximately 75 centimetres: and a raised configuration where the working height is approximately 110 centimetres.

[0018] In other examples, the working height in the raised configuration is approximately 100 centimetres.

[0019] In some examples, the working height is 120 millimetres, or less, above the clearance height. In further examples, a weight scale is provided between the working surface and the clearance zone, wherein a height of the weight scale between the first working surface and the clearance zone is 120 millimetres or less.

[0020] In some examples of the retail checkout, a conveyor belt surface of the conveyor belt system is substantially coplanar with the first working surface.

[0021] In some examples of the retail checkout, the bagging section further comprises a first collection surface, wherein the first collection surface is substantially coplanar with the first working surface.

[0022] In some examples of the retail checkout, a proximal portion of the conveyor belt system at the conveyor end overhangs at least part of the clearance zone. The proximal portion has a proximal portion height of 120 millimetres or less.

[0023] In some examples of the retail checkout, the bagging section further comprises an operator bagging surface that is between 25 to 50 centimetres lower than the first working surface.

[0024] In some examples of the retail checkout, the bagging section further comprises: a rotatable turntable with a turntable surface that forms at least part of the operator bagging surface to support items and / or bags;a second collection surface that is substantially coplanar with the turntable surface; and a guide configured above at least part of the turntable surface, wherein on rotation of the turntable surface, the items and / or bags supported by the turntable surface are deflected by the guide from the turntable surface to the second collection surface.

[0025] In some examples of the retail checkout, the operator bagging surface is at an operator bagging surface height that is 30 centimetres to 90 centimetres above the floor.

[0026] In some examples of the retail checkout, the operator bagging surface is configured, at least in part, to a left side or a right side of a wheelchair received in the clearance zone.

[0027] In some examples of the retail checkout, the bagging section further comprises a customer bagging surface adjacent the second collection surface, wherein the customer bagging surface and the second collection surface are substantially coplanar.

[0028] In some examples of the retail checkout, the retail checkout is configured with each of: the conveyor end; first working surface; at least part of the first control surface; and the first bagging surface, to be within 600 millimetres of either shoulders of a seated operator in the wheelchair that is at least partially received in the clearance zone.

[0029] In some examples, the retail checkout further comprises a turntable actuator to selectively rotate the rotatable turntable.

[0030] In some examples of the retail checkout, a depth of the clearance zone, perpendicular to the width, is 50 centimetres or more. The depth is important to enable a seated operator to be closer to the first working surface and to be in reach of the conveyor end, and first bagging surface.

[0031] In some examples the retail checkout further comprises a first control input configured, at least in part, to receive user input to selectively adjust the adjustable supports, wherein the retail checkout further comprises a second control input located separately to thefirst control input, wherein retail checkout is configured to adjust the supports based on receiving user input to both the first control input and the second control input.

[0032] In some examples the retail checkout further comprises telescoping shroud covers to surround and guard the adjustable supports.

[0033] In some examples of the retail checkout, the adjustable supports synchronously raise or lower respective heights of the conveyor belt system, scanner system, and the bagging section.

[0034] In another aspect, there is provided a retail checkout comprising a scanner system and a bagging section to support items. The scanner system is configured to scan items and includes a first working surface wherein the first working surface is substantially planar and horizontal. The bagging section includes a rotatable turntable with a turntable surface to support items and / or bags, wherein the turntable surface is between 25 centimetres to 50 centimetres vertically lower than the first working surface. A second collection surface is provided that is substantially coplanar with the turntable surface. A guide configured above at least part of the turntable surface, wherein on rotation of the turntable surface, the items and / or bags supported by the turntable surface are deflected by the guide from the turntable surface to the second collection surface.

[0035] This enables transfer of bagged items to the second collection surface without requiring the operator to lift potentially heavy bags.

[0036] In some examples, the turntable surface is at a turntable surface height that is 30 centimetres to 90 centimetres above the floor.

[0037] In some examples, the retail checkout is further configured to include an operator station for an operator, wherein the retail checkout is configured with the scanner system toward a front of a torso of the operator at the operator station. The retail checkout is configured with, at least in part, the turntable surface to a left side or right side of the torso of the operator.

[0038] In some examples, the bagging section further comprises a customer bagging surface adjacent the second collection surface, wherein the customer bagging surface and the second collection surface are substantially coplanar.

[0039] In some examples, the retail checkout further comprises a turntable actuator to selectively rotate the rotatable turntable.

[0040] There is also provided a retail checkout system comprising two retail checkouts described above. The two retail checkouts may be configured as a pair with a central area in between the checkouts as a workspace for the operators.Brief Description of Drawings

[0070] Overview

[0071] Figs. 1 to 4 illustrates an example of a retail checkout 10 with adjustable height.This includes a conveyor belt system 16 to convey items to a conveyor end 17. A scanner system 22, to scan items, is provided between the conveyor end 17 and a bagging section 30. The bagging section 30 is provided to support scanned items and / or bags for an operator to place scanned items.

[0072] One or more adjustable supports 82 support the conveyor belt system 16, scanner system 22, and the bagging section 30. The adjustable supports 82 are selectively adjustable to raise or lower a height of the conveyor belt system 16, scanner system 22, and the bagging section 30.

[0073] Figs. 1 and 2 illustrates the retail checkout 10 at a lowered height 93 that can be suitable for a seated operator, such as an operator in a wheelchair. Figs. 3 and 4 illustrates the retail checkout 10 at a raised height 95 that may be suitable for a standing operator. It is to be appreciated that other heights may be selected by the operator to accommodate their respective heights, posture, and ergonomic requirements.

[0074] To assist seated operators, such as those in wheelchairs, the retail checkout may also include a clearance zone 80 below the scanner system 22. In this non-limiting example, the clearance zone 80 is also between two of the adjustable supports 82. The clearance zone 80 is configured with a width 91 to receive a lower leg region of a wheelchair 3 or a seated individual. This enables a seated operator to comfortable sit closer to the scanner system and assist the operator to reach and manipulate items at the conveyor end 17, scanner system 22, and the bagging section 30 (as best illustrated in Fig. 16).

[0075] In some examples the width 91 is at least 60 centimetres. In other examples, the width 91 is at least 80 centimetres. In some examples the width 91 is around 82 centimetres. In some further examples, the width 91 is 82 centimetres or greater. In some examples the width 91 is around 84 centimetres. In some other examples, the width 91 is 84 centimetres of greater. The minimum width 91 can include, or be at least, the typical width of a doorway (or other passage) that is wheelchair accessible.

[0076] Another aspect of the retail checkout 10 includes the bagging section 30 to aid the operator to bag scanned items and the transfer filled bags. The bagging section 30 includes a rotatable turntable 34 with a turntable surface 35 to support items or more bags to be filled with scanned items. The bagging section also includes a collection surface 36 that is substantially coplanar with the turntable surface 35. A guide 40 is configured above at least part of the turntable surface 35. After the operator finishes filling a bag at the turntable surface 35, the turntable surface is selectively rotated so that bags (or items) supported by the turntable surface are deflected by the guide 40 towards the second collection surface 36. Referring to the example in Fig. 1 (and from the perspective of looking downwards towards the turntable surface 35, this will include a clockwise rotation of the rotatable turntable 34).

[0077] Advantageously, the bagging section 30 with the rotatable turntable 34 enables transfer of loaded bags to the collection surface 36 without the operator having to lift the bags.This may be important for ergonomic and safety reasons. This may be particularly advantageous for an operator in a wheelchair where the collection surface 36 may be out of reach for them.

[0078] The components of an example system will now be described in detail.

[0079] Conveyor belt system 16

[0080] Referring to Fig. 2, the conveyor belt system 16, includes a conveyor belt 19 in a continuous loop. The conveyor belt system 16 is configured to have a portion of a conveyor belt surface 15 that face upwards to receive items to be conveyed by the belt 19. The conveyor belt can be selectively driven by an actuator, such as an electric motor, so that items are conveyed along a longitudinal axis 21 towards the conveyor end 17.

[0081] Proximal to the conveyor end 17, the conveyor belt system 16 includes one or more sensors 23 to detect items at the conveyor end 17. When the sensors 23 detects items at the conveyor end 17, the conveyor belt 19 is stopped. Conversely, when the sensors 23 do not detect items at the conveyor end 17, the conveyor belt 19 can be configured to resume conveying items on the belt surface 15 towards the conveyor end.

[0082] The sensors 23, may include a light source and photodiode detector. This includes detecting an interruption (such as by items at the conveyor end 17) that stops light from the light source from being received at the photodiode detector.

[0083] The conveyor belt surface 15 can be substantially flat and horizontal so that items on the surface 15 do not inadvertently roll. In some examples the conveyor belt surface 15 is coplanar with a first working surface 31 of the scanner system 22. This enables an operator to move the item from the conveyor end 17 to the scanner system 22 (for scanning) with minimal lifting. In some examples, the operator may slide the item from the conveyor end 17 to the first working surface 31 for scanning.

[0084] A portion of the conveyor belt system 16 may extend above the clearance zone 80. In particular, the conveyor end 17 may be located above the clearance zone 80 so that the operator can manipulate items from the conveyor end 17 without moving their entire body, reaching over, and / or straining their body.

[0085] Referring to Fig. 1, a consideration includes providing a working height 84 (of the first working surface 31 and conveyor belt surface 15) from a floor 89 that is comfortable for the arms of the operator. This is also balanced with providing a clearance height 87 that is sufficiently large to enable a wheelchair 3 and the operator’s legs to pass under. Thus, it is desirable to have a low height profile for the scanner system 22 and the end of the conveyor belt system 16. That is, a low height thickness to reduce compromise of comfort for the operator.

[0086] Figs. 5 and 6 illustrate views of two example types of conveyor modules 92 that have a conveyor belt 19 in a continuous loop and driven by drive unit 104 that is flanked by side walls 102. The modules include a light duty conveyor 94 and a heavy-duty conveyor 96. The main difference between the light duty and heavy-duty conveyor 96 is that that heavy duty conveyor is configured to higher capacity and as a result utilises a larger drive unit 104.

[0087] In the light duty conveyor 94, the drive unit 104 may be sufficiently small such that it can be located proximal the conveyor end 17 without resulting in a thickness that would compromise the clearance zone 80 of working height 84. In some examples, the light duty conveyor module 94 may be approximately 90mm thick in height. In some examples, the lightweight conveyor is rated to move approximately 75kg of items on the conveyor belt 19.

[0088] In the heavy-duty conveyor 96, the drive unit may be substantially larger in diameter such that placement at the conveyor end 17 would compromise the clearance zone 80. To enable a lower profile near the clearance zone, the drive unit 104 is shifted away from the conveyor end 17 as illustrated in Fig. 6 so that the drive unit 104 does not interfere with the clearance zone 80. In some examples, the heavy-duty conveyor 96 is approximately 110mm thick in height at the conveyor end 17 and approximately 185mm thick in height near the drive unit 104. The heavy-duty conveyor may be rated to move approximately 100kg of items on the conveyor belt 19.

[0089] Referring to the example of Fig. 1, a proximal portion 81 of the conveyor belt system 16 at the conveyor end 17 overhangs at least part of the clearance zone 80. Similar to the scanner system 22, it is desirable to provide ample clearance for a seated operator and wheelchair that can be positioned underneath the proximal portion 81. This the proximal portion 81 may be configured to have a proximal portion height 79 of 120 millimetres or less.

[0090] It is to be appreciated that other dimensions and design specifications can be utilised for the conveyor modules 92.

[0091] Scanner system 22

[0092] The scanner system 22 is configured to receive information on the item(s) purchased by the customer. In some examples, the scanner system 22 includes one or more barcode scanners 33 to obtain barcode information from the item. In some examples, a barcode scanner 33 includes an optical scanner that projects one or more laser light towards the barcode for a sensor to read the reflected light. In the illustrated example, one barcode scanner is configured to scan upwardly through the first working surface 31 (such as through a transparent glass pane). An additional barcode scanner 33’ is provided perpendicular to the first working surface 31 to provide additional scanning options from the side.

[0093] In some examples, the scanner system 22 includes a weight scale 24. The scale 24 may be provided as part of the first working surface 31. Thus an operator can place an item on the scale to obtain the weight of the item in circumstances where the price of the item is sold by weight (such as some fruits and vegetables).

[0094] In further examples, the scanner system 22 may include one or more cameras to obtain images of the scanned item. These images may be used to determine the type of item scanned. This may include using machine learning models to identify the type of item scanned by the scanner (for example, identifying a particular type of fruit or vegetable).

[0095] The first working surface 31 of the scanner system 22 may also provide a resting surface to support the item. Thus, an operator may move the item from the conveyor end 17 to be supported by the first working surface 31 before scanning (or simultaneously during scanning). This can be particularly useful for bulky and heavy items or for items that need weighing.

[0096] In some examples, the first working surface 31 is substantially planar and horizontal to provide a stable platform. This can include having the first working surface 31 substantially coplanar with the conveyor belt surface 15 so that the operator may move itemsfrom the conveyor end 17 to be scanned with minimal lifting. In some examples, this may even facilitate sliding of the items from the conveyor end to the first working surface 31.

[0097] The selection of a working height 84 of the first working surface 31 is ergonomically important and depends on factors including a standing or sitting operator, height and other physical dimensions of the operator, size and configuration of the wheelchair or chair, etc. In some examples, the adjustable supports 82 are configurable to provide a working height 84 of the first working surface 31 of between 60 centimetres to 120 centimetres from the floor 89.

[0098] In some examples, the lowered configuration 93 (as illustrated in Figs. 1 and 2) has a working height of 84 of approximately 75 centimetres. This may be a desirable height for an operator in a wheelchair so that their arms are at a suitable height to manipulate items in their workspace. It is to be appreciated finer adjustments up or down could be made to suit the individual operator’s physique.

[0099] In some examples, the raised configuration 95 (as illustrated in Figs. 3 and 4) has a working height 84 of between 100 to 120 centimetres. In some examples the working height is approximately 100 centimetres. In other examples, the working height is approximately 110 centimetres. In yet other examples, the working height is approximately 120 centimetres. This may be a desirable height for a standing operator. Further user selectable height adjustments may accommodate for the height of the operator.

[0100] In some examples, with reference to Fig. 1. the working height 84 is 120 millimetres or less above the clearance height 87. This can be achieved by having a height 39 of the scanner system 22 at the first working surface 31 to be 120 millimetres or less. In some examples, the weight scale 24 is provided between the first working surface 31 and the clearance zone 80, and the weight scale 24 is configured so that the height 39 of the weight scale between the first working surface 31 and the clearance zone 80 is 120 millimetres or less. Accordingly, the clearance height 87, when in the raised configuration 95, may be between 90 to 110 centimetres. In some examples, the clearance height 87, when in the raised configuration 95, is approximately 100 centimetres.

[0101] The scanner system 22 may include, or be connected to, one or more point of sale (POS) devices, such as a POS display 18 (see Figs. 8 and 9) and a processing device / computerthat is connected to a database and / or network. The POS display 18 may include a touchscreen to enable an operator to provide additional information, correction, or other user input. In some examples, the POS display 18 may also provide billing information to the customer. A payment terminal 28 is also provided to enable the customer to pay electronically, such as via a credit card, debit card, mobile device, etc.

[0102] A printer 26 may also be provided to print receipt for the customer. A printer drawer 46 (as illustrated in Figs. 1 and 7) is provided adjacent to the wheelchair clearance zone 80 so that it is easily reachable and serviced by the operator (including a seated operator). This may include a slidable printer drawer 46 that carries the printer 26 and spare printer rolls 64. As the printer 26 slides with the drawer 46, this enables the operator to easily change paper rolls.

[0103] Wheelchair clearance zone 80

[0104] The clearance zone 80 is provided to enable the lower legs and (at least in part) the thighs of a seated operator. The clearance zone 80 can be configured to provide enough room for a wheelchair and the operator. It is to be appreciate that in some alternative use cases, an operator may sit on a chair and have their lower legs in the clearance zone 80.

[0105] Referring to Fig. 1, the wheelchair clearance zone 80 is, at least in part, below the scanner system 22. As a consequence, the wheelchair clearance zone has a clearance height 87 from the floor 89 that is dependent on the selective adjustment of the supports 82. In some examples, the clearance height 87 from the floor is between 50 centimetres and 100 centimetres.

[0106] In some examples, when the retail checkout is in the lowered configuration 93 (as illustrated in Fig. 1), the clearance height 87 is approximately 68 centimetres. In other examples, the clearance height in the lowered configuration 93, is between 60 centimetres ad 70 centimetres, and in some examples approximately 65 centimetres. It is to be appreciated that the operator may raise the scanner system 22 higher to provide a higher (or lower) clearance height 87 based on their individual body size and wheelchair / chair configuration.

[0107] The wheelchair clearance zone 80 also includes a width 91 to accommodate a width of the wheelchair or an otherwise seated individual. In some examples, this width is at least60 centimetres. In other examples, this width is approximately 84 centimetres, in alternative examples approximately 82 centimetres, and in other examples approximately 80 centimetres. In yet other examples, the width is between 80 to 100 centimetres. In some example the width 91 is at least 80 centimetres. In another example the width is at least 82 centimetres. In yet further examples the width is at least 84 centimetres.

[0108] In some examples, the wheelchair clearance zone 80 is configured between adjustable supports 82. In particular between the first support group 83 that supports the conveyor belt system 16 and a second support group 85 that supports the bagging section 30. Thus a wider clearance zone 80 can be achieved by widening the distance between the first and second support groups 83, 85.

[0109] The depth 77 of the clearance zone 80 (which is perpendicular to the width 91) may be dependent, at least in part, on the dimensions of the scanner system 22 and / or width of the conveyor belt system 16. It may be advantageous to provide a foot guard 44 (as illustrated in Fig. 2) to shield an operator’s feet and their wheelchair from entering into customer side of the checkout. This is important to prevent a customer pushing a trolley and impacting the feet or wheelchair of the operator. In addition, a conveyor deflector 42 is provided to guide trolleys in the customer side away from the workspace near the operator.

[0110] In some examples, the depth 77 of the clearance zone 80 is at least 30 centimetres. In other example, the depth of the clearance zone 80 is at least 50 centimetres. In some examples, the depth of the clearance zone 80 is approximately 56 centimetres. In further examples, the depth 77 of the clearance zone 80 substantially occupies the entire area under the scanner system 22. The depth 77 of the clearance zone 80 enables the feet (an at least part of the legs) of a seated operator, as well as part of a wheelchair, to be positioned underneath the first working surface 31.

[0111] Bagging section 30

[0112] The bagging section 30 will now be described with reference to Figs. 8 and 9. The bagging section 30 includes a first collection surface 32 that is adjacent to the first working surface 31 at the scanner system 22. In this example, an area of the first collection surface 32 is substantially coplanar with the first working surface 31. That is, horizontal and at the samelevel. This enables an operator to slide or place the scanned item at the first collection surface 32 without excessive lifting.

[0113] In some examples, as illustrated in Fig. 8, the first collection surface also includes a sloped portion 29 that extends from horizontal level portion. The sloped portion 29 may assist gentle movement of the items away from the first working surface 31. The sloped portion 29 includes raised edges to prevent items from slipping off the collection surface.

[0114] From the first collection surface 32, items can be moved for bagging into shopping bags. The example bagging section 30 can provide multiple options including enabling an operator to bag items in a bag located at an operator bagging surface 35 (as illustrated in Fig. 8). Alternatively, the customer may take the scanned items themselves directly from the first collection 32. Referring to Fig. 9 the customer may also bag items themselves from a customer bagging surface 38.

[0115] Turning back to Fig 8, the operator bagging surface 35 is preferably vertically lower than the first collection surface 32. In particular, the height difference should be the same or more than the expected height of walls of grocery bags. In some examples, the operator bagging surface 35 is between 25 to 50 centimetres lower than the first working surface 31. This enables an operator to scan and bag items without having to substantially lift items vertically upwards.

[0116] In addition, an operator bagging surface height 37 between the operator bagging surface 35 and the floor is also an important ergonomic consideration (see Fig. 1). In some examples, retail checkout is configured so that the operator bagging surface height 37 is between 30 centimetres to 90 centimetres above the floor. This operator bagging surface height 37 may be selectively adjustable along with the bagging section 30. For a seated operator in a wheelchair, the operator bagging surface height 37 is preferably low such as between 30 to 50 centimetres above the floor.

[0117] To enable ease of movement of bags filled with items, the bagging section 30 includes a rotatable turntable 34, where at least part of a turntable surface (proximal to the operator) forms the operator bagging surface 35. The turntable surface is configured to support bags and / or items. In practical use, an operator can sit a bag on the turntable surfaceand place scanned items to fill the bag. Once the operator has finished bagging the bag, the rotatable turntable is selectively rotated (such as in direction 51) so that items supported by the turntable surface 35 are moved towards a guide 40. The guide 40 then deflects the bag and / or items from the turntable surface 35 towards a second collection surface 36.

[0118] The guide 40 is located above at least part of the turntable surface. Preferably, the guide extends substantially near a centre of the turntable to at least an outer perimeter of the turntable 34. The guide 40 may form part of a wall surface leading up to the first collection surface 32. In this example, the guide 40 is stationary relative to the movement of the rotatable turntable and it is to be appreciated that the guide 40 may be profiled and / or angled so that bagged items are gently deflected to the second collection surface 36.

[0119] The second collection surface 36 may be substantially coplanar with the turntable surface 35 to aid sliding of bags and items to the second collection surface 36 and to reduce risk of damage to items or items moving in the bags. In some examples, the second collection surface 36 may also include a sloped portion (not shown) to assist movement of the bags away from the rotating turntable 34 to make room for subsequently filled bags.

[0120] Referring to Fig. 8, the rotatable turntable 34 preferably has a round turntable surface (but only part of which is exposed as the operating bagging surface 35). The turntable may include a rubber or rubber-like surface to provide some grip to the bag. In some examples, the turntable 34 is manually moved by the operator, such as by hand.

[0121] In some examples, with reference to Figs. 8 and 14, the operator bagging surface 35 is configured at least in part, to a left side or a right side of a wheelchair received in the clearance zone 80. This can advantageously reduce how far a seated operator needs to reach to move items from the first working surface 31 (or first collection surface 32) to bags at the operating bagging surface 35 (being, in this example, the exposed part of the rotatable turntable surface 34).

[0122] Referring to the example illustrated in Fig. 16, this includes an operator station 43 for the seated operator wherein the retail checkout 10 is configured with the scanner system 22 towards a front of a torso of the operator at the operator station. The retail checkout is configured with, at least in part, the turntable surface 34 (being the operating bagging surface35) to a right side of the torso of the operator. It is to be appreciated that other examples as shown in Fig. 14 can provide the turntable surface to the left side of the torso.

[0123] In other examples, the rotatable turntable 34 may be actuated by a turntable actuator (such as a selectively operable motor) to rotate the rotatable turntable 34. This may include one or more operator-controlled inputs (such as switches) to selectively enable rotations.

[0124] Near the periphery of the turntable 34, and adjacent the operator, the sides of the furniture forming the bagging section 30 may include curved or round sides 48 to reduce chances of injury to the operator. To the other side of the operator, the retail checkout 10 may also include control panels 52, 54 and a cash drawer 50.

[0125] In known checkouts the bagging areas may include a carousel for suspending an open bag so that they can be filled and rotated away from the operator. It has been identified that when seated, the human body should not be lifting heavy bags as it can cause shoulder injury. Accordingly, the carousel approach to removing bagged groceries from the immediate vicinity of a seated operator 12 should be avoided. The presently described bagging section with rotatable turntable 34 and guide 40 provides an advantage over such known carousels. This includes enabling a seated operator to simply pack bags on the lower-level operator bagging surface 35 and then simply rotating the turntable to move the bags away to the second collection surface 36 without requiring the operator to lift loaded bags.

[0126] Adjustable supports 82

[0127] The adjustable supports 82 may include actuators to raise and lower the heights of the conveyor belt system 16, scanner system 22 and bagging section 30. This can include selectively operable motors to rotate screw / threaded elements to raise and lower such components. Importantly, when the motors are off (such as when power is cut) additional movement up or down is prevented. This can be part of a safety mechanism for operator, or for maintenance personnel, so that cutting power will prevent (or reduce) the likelihood of additional movement and / or crush injuries.

[0128] Figs. 11 and 12 illustrate the example retail checkout 10 with protective shroud covers 76, 78 removed. The adjustable supports 82 include a first support group 83 to supportthe conveyor belt system 16 and a second support group 85 to support the bagging section 30. In this example, each of the first and second support groups 30 include a pair of telescoping supports. Each telescoping support is made from a top support 86 that slides in and out of bottom support 84 as shown in Fig. 11. The telescoping supports 82 are connected at their undersides to support base 88 (as illustrated in Fig. 10) to enable the checkout 10 to be fixed to the floor surface.

[0129] In some examples, each of the telescoping supports include corresponding step drives, servos, or motors that are controlled by microcontrollers associated with a first control input (such as control panel 54) and a second control input (such as control switch 52 in Fig. 8). These first and second control inputs 52, 54 are located separately and spaced apart but within reach of respective hands of an operator to provide user input. For safety, the retail checkout 10 is configured so that user input to both the first control input 54 and the second control input 52 is required to adjust the supports 82. This ensures that an accidental bumping of one of the control inputs would not result in inadvertent movement of the adjustable supports 82.

[0130] In specific examples, the control panel 54 enables the operator to select a specific height or provide a raise / lower command. The control switch 52 may be used to provide a confirmation command.

[0131] Additional safety mechanisms may be provided to prevent or reduce instances of injury. In some examples, proximity sensors 56 may be mounted to the underside of the scanner system 22 (see Fig. 11). These sensors face towards the clearance zone 80 and are configured to intervene and stop the lowering of the checkout 10 if they sense objects such as the legs of an operator. The pressure or contact sensors may be in the form of a safety sensor strip that runs across the underside of the scanner system 22 (such as across the width of the clearance zone 80). This may include safety cut off circuits and switches. In other alternate embodiments, pressure or contact sensors may be provided and the controllers configured such that on sensing pressure or contact, the checkout 10 is moved in the opposite direction. This can include moving in the opposite direction for a specified distance, such as 10 to 25 millimetres. In further examples, the retail checkout 10 is configured to further require a gate 160 to be closed before the actuator move the supports 82 .

[0132] In preferred examples, the multiple adjustable supports 82 operate synchronously to raise or lower the supported conveyor belt system 16 and bagging section 30 (as well as the connected scanner system 22 bridging over the wheelchair clearance zone 80). That is, all four top supports 86 (see Fig. 11) will be raised or lowered in unison.

[0133] Referring to Fig. 11, the top supports top supports are connected, in part to a conveyor frame 98, bagging section 30 or top support mounts 90. An example of actuators includes step motors provided by LINAK A / S Nordborg, Denmark. Model LC1 which has a maximum degree of motion or strike length of 700mm providing 2500N of lifting force in three lifting stages, or Model DL-2-300-455-1500N CBD4 which has a maximum of 500mm of stroke length and 2500N in lifting force in two lifting stages.

[0134] In some examples, additional sensors included to provide closed-loop feedback control. In some examples, this can include accelerometers to provide an indication of deflection (such as pitch and roll) of the checkout 10. It is to be appreciated that other sensors, such as tilt sensors could be used. In yet other examples, displacement sensors, are provided on the telescoping supports 82. These can be used to control, and confirm, that the checkout 10 is in the general horizontal and flat configuration during height adjustment.

[0135] In some examples, the sensors may provide an output indicative of the level of the conveyor belt system 16. In further examples, the sensors may provide an output indicative of angles around multiple axes, such as x, y, and z axis that are perpendicular to each other). A controller is configured to control the actuators of the adjustable supports to level the retail checkout 10 as the height is raised and lowered.

[0136] Additionally, if the control unit of the telescoping supports 82 senses that the supports 82 have become unlevel or out of synchronisation, the supports 82 may enter a recalibration mode. This may include only enabling the support to lower and once at their lower most position, reset and allow the checkout 10 to be raised again in synchronised unison. It is to be appreciated that in alternative examples, recalibration may be at the upper most position.

[0137] Fig. 12 illustrates a schematic 100 for a control system to control the adjustable supports and the scanner system (including POS system and payment terminal). In someexamples, these components may be in communication with one another. The safety cut off switch 56, in some examples, may include a reed switch configured to detect a closed gate 160.

[0138] Referring to Figs. 1 to 4, one or more shroud covers 76, 78 can be configured to surround and guard the adjustable supports 82. This can include a system of telescoping shrouds such as an upper support shroud cover 76 and a lower support shroud cover 78. As illustrated in Fig. 3, the lower support shroud cover 78 telescopes into the upper support shroud cover 76. The shroud covers protects the interference with the adjustable supports 82. It can also serve as a safety mechanism to prevent the operator, wheelchair, shopping trolley, or customer from easily accessing the moving parts and electrical components in the adjustable support 82. As shown in Fig. 1, the shrouds are provided at either side of the wheelchair clearance zone 80 to protect the seated operator.

[0139] Referring to Fig. 1, the shrouds may be configured such that even at the lowest position for the retail checkout 10, the bottom edge of the upper support shroud cover 76 includes a clearance gap to the floor. This clearance gap can be designed to be larger than the height of a typical shoed foot to prevent a foot of a customer, or other person, from being crushed as the checkout 10 is lowered.

[0140] Retail checkout system 2

[0141] Figs. 13 and 14 illustrates an example of a retail checkout system 2 that includes a pair of retail checkouts 10. A central module 20 is provided in between. The pair of retail checkouts may be independently adjustable in height based on the operators’ needs. This can include one operator standing while the other operator is sitting in a wheelchair.

[0142] Fig. 14 illustrates a top view of the retail checkout system 2 where this example has a clearance of approximately 900 millimetres between the bagging sections 30 (to provide wheelchair access to the operators) and approximately 1400 millimetres between the conveyor belt systems 16 and scanner systems 22.

[0143] The retail checkout system 2 may also include customer aisle gates 60 to control the customer aisle and checkout entry barriers 62 to partition the operator’s workspace.

[0144] Referring to Fig. 15, the central module 20 feature storage zones which can be used to store all the consumables that a checkout operator would require to operate the checkouts 10. Alternatively, or in conjunction, the central module 20 can be used to anchor promotional materials 68 or shelving for vendible products including refrigerators (not shown). The central modules 20 may have covers which can be removed to access the data and electrical modules inside. These can include sources of power and data for the checkouts 10 which access the data and power through data access slot 74. The central module 20 may include additional storage 71 which can be used to store a walking aid.

[0145] Advantages

[0146] Advantages of the present disclosure have been described throughout this specification. This includes the ability to be configured for use by an operator sitting in a wheelchair as shown in Figs. 16 and 17 whilst also allowing the retail checkout 10 to be configured to be used by a standing operator as illustrated in Fig. 18.

[0147] The ability to convert the checkout 10 to be raised or lowered depending on the operator needing or wishing to sit is a key advantage over known checkouts. Furthermore, the described checkout may also assist standing operators by enabling adjustment of height of the workspace. This can be particularly advantageous for operators who are significantly taller or significantly shorter than average heights. In addition, this adjustment may be beneficial for workers who have injuries or other conditions that limit the range of motion of their hands and arms.

[0148] In some examples, a workspace with a lowered height 84 of approximately 750 millimetres above the floor is appropriate for some operators in a wheelchair as illustrated in Fig. 17. In some examples, a workspace with a raised height 84 to approximately 1000 millimetres above the floor is appropriate for some operators who are standing.

[0149] Turning to Fig. 16, this shows a top view of an operator in a wheelchair and the reach 61 of their arms of approximately 600 millimetres from respective shoulders. This shows that the operator can reach and place items from the conveyor end 17, scan items at the scanner system 22 at the first work surface 31, manipulate items at the first collection surface 32, and bag items into bags at the first bagging surface 35.

[0150] In some examples, this can include configuring the retail checkout 10 so that each of the conveyor end 17, first work surface 31, and first bagging surface 35 is within 600 millimetres of either shoulders of a seated operator in a wheelchair at the operator station 43. In this example the wheelchair is at least partially received in the clearance zone). In further examples, at least part of the first collection surface 32 is also within 600 millimetres of either shoulders of the seated operator. This configuration improves ergonomics for a seated operator and reduces stretching / reaching for items as they are moved to different areas of the retail checkout 10.

[0151] Variations

[0152] It is to be appreciated that some variations of the retail checkout include adjustable supports to vary the height of the checkout but does not include a rotatable turntable at the bagging section.

[0153] In other variations, the retail checkout is permanently, or semi permanently, set with a low workspace height which may be suitable for circumstances where the operator is expected to be seated or in the wheelchair. In such variations, the retail checkout can include the rotatable turntable t, guide 40, and second collection surface 36 to assist the operator to transfer bagged items.

[0154] In some examples, covers, shrouds and maintenance access panels may include one or more switches. These can include mechanical, electrical, and / or magnetic switches that act as cut-off control signals and / or power to the motors. This can be advantageous as a safety feature to ensure actuators, such as servos and motors, do not inadvertently move during maintenance operations.

[0155] Further example of a retail checkout 110

[0156] Figs. 19 to 22 illustrate another example of the retail checkout 110. This retail checkout 110 shares some common features with the retail checkout 10 described in earlier examples above. Such common, or similar, features are provided with the same reference numerals.

[0157] Figs. 19 and 20 shows the retail checkout 110 from the operator side in the lower configuration and raised configuration, respectively. Figs. 21 and 22 illustrate the retail checkout 110 from the customer side. In this example there are three operator supports 82. The first support group 83 having two adjustable supports 82 to support the conveyor belt system 16. The second support group 85 including one adjustable support 82 to support the bagging section 30. Like the earlier example, the scanner system 22 bridges over the clearance zone 80 where it is functionally supported by the first and second support groups 83, 83.

[0158] In contrast with the earlier examples, the adjustable supports 82 in this example does not have additional protective shrouds 76, 78 installed. In this example, the adjustable supports 82 include telescoping members to reduce pinch risks during adjustment.

[0159] The retail checkout 110 also includes baggage hooks 111, 112. The first set of baggage hooks 111 are positioned above the first bagging surface 35. This enables the operator to secure bags at the first bagging surface 35 to facilitate loading of items into the bag by the operator. The second set of bagging hooks 112 are positioned above the customer bagging surface 38. This enables the customer to secure their bags above the customer bagging surface 38 in the event the customer elects to bag items themselves.

[0160] The retail checkout 110 also includes an oversize bag tray 114. Referring to Fig. 23(a), the oversize bag tray 114 is in the stowed configuration. Fig. 23(b) illustrates the oversize bag tray 114 slid out in the deployed configuration. A vertical barrier 116 at one edge of the oversize bag tray moves with the oversize bag tray. A second vertical barrier 118 is fixed proximal to the turntable 34. An operator can position an oversized bag between the vertical barrier 116 and second vertical barrier 118 and have the weight supported by the oversize bag tray 114. The oversize bag tray 114 may be useful in circumstances where the bag is too big for the first bagging surface 35.

[0161] The edges of the second collection surface 36 are guarded by a raised rubber lip 122 to prevent bags and items from sliding off the second collection surface 36. The rubber at the perimeter edges may also extend to a downward lip 124. Thus the rubber also forms as a guard around the perimeter of the second collection surface 36 to reduce adverse effects fromimpacts, such as from a shopping trolley. This guard also reduces potential of injury if a person, such as a child, bumps into the edge of the second collection surface 36.

[0162] The retail checkout 110 also includes a gate 160. Figs. 21, 22 and 24 illustrate the gate 160 opened to enable customers to pass through the checkout 110. In this opened configuration, the gate 60 can function as a modesty barrier to a seated operator. Fig. 25 illustrates the gate 160 in a closed configuration to provide a barrier to stop, or dissuade, a customer from using the checkout 110 when it is not in use.

[0163] Turning to Figs. 25 to 28, the gate 160 includes mechanisms to open and close the gate. This is achieved by a system as illustrated in Fig. 27 to 28. The hinge system 162 is a mechanical hinge to enable a person to open the gate from a closed configuration.

[0164] A person can manually open the gate by manually manipulating the gate to overcome the detent mechanism illustrated in Figs. 27 and 28. Referring to Fig. 27, the first hinge system 162 includes a pivot 164, a horizontal bar 165, and a recess 166 to selectively receive the horizontal bar 165. These components are mounted to a base 167, where the base 167 is in turn mounted to the conveyor belt system 16 of the checkout 10.

[0165] When a person wishes to manually open the gate 160, the gate 160 may be pushed open, whereby the horizontal bar 165 rises vertically up (e.g. along the axis of the pivot 164) to overcome the recess 166 as illustrated in Fig 28). In some examples, moving the gate 160 open requires overcoming the weight of the gate 160 to pass up and out of the recess 166. In some examples, the recess 166 is profiled so that has the gate 160 is moved around the pivot 164, the gate 160 is biased upwards. In other examples, a person needs to lift the gate out of the recess 166 before the gate can be opened around the pivot 164.

[0166] In alternative examples (not illustrated), the hinge system includes an actuated hinge mechanism that is actuated in response to an operator input from the control panel 54, In further examples, the actuated hinge system may operate automatically in response to other inputs or parameters. This can include time of day, shift times, proximity sensors detecting an operator at the checkout, etc.

[0167] The actuated hinge mechanism may include an electro-mechanical system configured to rotate the gate 160.

[0168] In yet other examples (not illustrated) the mechanism to open and close the gate may include two parallel hinge systems. This can include an actuated hinge mechanism and a mechanical hinge. This can enable operation of the gate manually or with an actuator.

[0169] In some examples, a sensor is provided to sense the position of the gate 160. This can include a reed switch, microswitch, encoder, etc. In particular examples, the sensor is configured to provide an output indicative of the gate in the closed configuration. As a safety mechanism, the checkout may be configured so that the adjustable supports can only be raised or lowered on the condition that the gate 160 is closed. This can prevent or reduce the chance of the movement of the retail checkout causing injury and / or damage.

[0170] Referring to Fig. 24 a minimum vertical clearance 180 is provided on any moving part of the retail checkout 110. In particular, a minimum vertical clearance 180 is provided to prevent unintended downward crushing on objects / persons below the retail checkout 110. In some examples, this minimum vertical clearance 180 is around 300mm. In other examples, this minimum vertical clearance is around 310mm. In other example, this minimum vertical clearance is at least 400mm.

[0171] It will be appreciated by persons skilled in the art that numerous variations and / or modifications may be made to the above-described embodiments, without departing from the broad general scope of the present disclosure. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
