Description

The present invention relates to a cashier system according to the preamble of claim 1, a method for operating a cashier system and a computer program and a machine-readable storage medium for operating a cashier system. These aspects of the invention serve to create variable size dunnages in a packing zone of the cashier system.

A provided for example for use in a supermarket cashier system usually includes a goods receiving device in the form of a conveyor belt, on which a customer can place his goods for the purpose of registration and the subsequent payment. Goods from different customers are separated from each other by so-called goods separators, so that the goods are not confused. The goods are then conveyed by the conveyor belt to a goods detection device, which may be designed, for example, in the form of a tunnel scanner. From the tunnel scanner or other goods detection device, the goods are registered automatically and / or manually by a cashier.

After registering, the goods are usually supplied to a goods receiving device downstream goods issue device, the registered goods along a conveyor line in a transport direction in a further Packing zone transported. There, a customer can take the registered goods and pack.

Such a cashier system, which is also referred to as a checkout terminal, is for example from the WO 2005/084227 A2 known.

Another goods receiving device is from the DE 10 2008 044 795 A1 known. The goods receiving device is pronounced there in the form of a conveyor belt and has a plurality of so-called driver and a goods detection device in the form of a tunnel scanner. There it is described that the carriers are coupled to one another via a plurality of belts and arranged above the conveyor belt. The movement of the composite of belts and carriers is synchronized with the movement of the conveyor belt via a control device. The control device ensures that the conveyor belt and the carriers move with the straps at the same speed, so that the goods are not pushed or braked by the carriers on the conveyor belt.

A disadvantage of the prior art cashier systems is that goods of different customers or different shopping carts quickly get mixed up in the packing zone. Although the packing zone can be divided by manually operated folding beams in usually two separate packing troughs. However, packing pits created in this way are usually the same size in terms of their area and further limited in number, for example to two packing pits. This solution is not practical, in particular, for self-service checkout systems that are designed to relieve or avoid cashiers.

The object underlying the present invention is therefore to provide means with which a practicable and efficient use of a packing zone of a cashier system can be achieved.

This object is achieved by an article according to one of the independent claims. Features of advantageous developments are given in the dependent claims.

According to a first aspect of the present invention, a cashier system according to claim 1 is proposed.

The checkout system according to the invention is characterized by a goods issue device which is designed to fix a goods separator on a receiving device of the goods issue device, to subdivide the conveyor line in a Nacherfassungszone for retrieval of goods and in a packing zone for removing goods.

The present invention is based on the recognition of determining the number and size of packing pits by the size or quantity of goods to be registered and by the number of shopping carts. If many and each small shopping carts are processed, several smaller packing pits are needed in the packing zone. If individual large shopping carts are processed, then rather less, but larger packing pits are required in the packing zone. In the context of the present invention, it has been recognized that the goods separators, which are used anyway in the goods receiving device for separating different shopping carts, can also be used to insert the shopping carts in the packing zone of a goods dispensing device of a cashier system.

The fixed goods separator can optionally be released automatically or manually, so that it is transported along the conveyor line. As a result of the cashier system according to the invention, in the packing zone, that is to say in a goods removal area of the goods issuing device, bounded pack cavities are produced by the product separators and variable in their respective size. Due to the temporary fixing of the goods separator, it is also easier for a cashier to retrieve goods located in the re-registration zone, which could not be registered by the goods detection device, for example, without mixing goods from different customers or different shopping carts.

The cashier system allows efficient use of the packing zone, because the limited by the item separators packing pits size in each case to the amount and size of goods of a shopping cart and thus no pack well more space required than is necessary for a particular basket.

Furthermore, the goods detection device, which is implemented, for example, in the form of a tunnel scanner, can be continuously utilized for a corresponding customer volume through the efficient use of the packing zone.

As a result, the cashier system according to the invention achieves a faster customer service compared to conventional cashier systems, which moreover is more customer-friendly than previously known cashier systems, in particular due to the clear delimitation of goods from different shopping carts in the packing zone.

The goods separator can be automatically transported to the receiving device or transported there manually, for example by a cashier.

For example, the goods separator fixed to the receiving device is released as soon as the subsequent detection of goods of a shopping cart has been successfully completed, so that the released goods separator can unlock along with the other goods on the conveyor line within the packing zone of the goods issue device.

The goods issue device is preferably designed to release the goods separator fixed to the receiving device in response to a control command and to convey it along the conveying path. For example, the control command for releasing the goods separator fixed to the receiving device is optionally given manually by a cashier and / or as a function of a control signal generated by the goods detection device, as will be explained below.

The released goods separator then closes with the other goods on the conveyor line of the goods delivery device in the transport direction, so that when this process is repeated in the packing zone of the goods delivery device form a plurality of packing pits, which are separated by goods separators and each one depending on the amount and / or size of goods have variable area.

Hereinafter, further embodiments of the cashier system according to the first aspect of the present invention will be described. The additional features of these embodiments may be combined with each other to form further embodiments unless expressly described as alternatives to each other.

In one embodiment of the cashier system, the receiving device is electrically controllable. This facilitates the fixing and releasing of a goods separator. For example, the electrically controllable receiving device is arranged on one or more side bands of the goods dispensing device, so that they fix a goods separator usually placed approximately perpendicular to the transport direction can, for example by exerting a corresponding attraction or holding force.

The receiving device preferably fixes the goods separator in such a way that goods arriving at the fixed goods separator are stowed and at the same time goods in the transport direction behind the goods separator can be conveyed in the transport direction. Thus, on the one hand a cashier can retrieve goods from a shopping cart of a customer, and on the other hand goods of a shopping cart of a preceding customer can be transported further in the transport direction so that the goods of the preceding customer collect in an end region of the packing zone of the goods issuing device. There, a customer can pack his goods without running the risk of mixing or swapping his goods with goods of other customers.

The receiving device is designed, for example, to fix the goods separator by exerting a magnetic force, and may for this purpose have one or more magnetic holding devices, for example in the form of switchable electromagnets. A goods separator, which usually has a rectangular or a triangular cross-section, has, for example, a magnetically conductive part at at least one end, which points to a side band of the goods delivery device, so that the goods separator is attracted and fixed by the magnetic force emanating from the receiving device can be.

The receiving device is purely mechanically implemented in another embodiment of the cashier system, for example in the form of a clamp receiving, which is designed to fix the goods separator by exerting a spring force, or by a number of substantially perpendicular to the transport direction arranged holding webs, which are formed Transporting the goods separator on the conveyor line in the transport direction to prevent. There are all types of recordings into consideration, which are designed to fix the goods separator temporarily, so that the temporarily fixed goods separator divides the conveyor line in the Nacherfassungszone for retracing goods and in the packing zone for removing goods.

Usually, the goods separator on an elongated shape and is substantially perpendicular to the transport direction of the goods receiving device and the Goods dispenser positioned. In addition to exerting a magnetic force and other mechanisms are conceivable, which are adapted to guide a carried on the goods issuing device goods separator in the receiving device and to fix there.

In one variant, a goods separator supplied via the goods receiving device is accepted by the goods delivery device and conveyed automatically or manually, for example by a cashier, into the receiving device, where the goods separator then locks in or is fixed in another way.

In a variant, the goods issue device is designed to control the fixing and / or release of a goods separator by the receiving device in response to a control signal provided by the goods detection device.

For example, the goods detection device is designed to detect a goods separator and to instruct the goods issue device by the control signal to release a preceding item separator on the receiving device. The generation of the control signal by the goods detection device can alternatively or additionally also take place depending on the number of goods of a shopping cart or of a customer registered by the goods detection device in a further variant.

In a preferred variant of the cashier system, the goods delivery device for transporting registered goods and goods separators on a sloping role field and / or a motorized conveyor belt. The sloping roller field and / or the motorized conveyor belt are preferably designed such that at a transition, a coupling of the goods issuing device to the goods receiving device can be made barrier-free.

The goods dispensing device of the cashier system has, for example, a guide device for conveying a goods separator in the transport direction along the conveying path. By means of the guide device, one or more goods separators in a predefined position (in which the goods separator is arranged, for example, with its longitudinal extension direction perpendicular to the transport direction) are conveyed along the conveying path. For example, this may be a goods separator to be arranged in a predefined manner on a conveyor belt, wherein the guide means different position positions for the goods separator on the Specifies conveyor belt and moves the goods separator in a movement of the conveyor belt together with the conveyor belt.

For example, the guide device comprises at least one guide groove or a guide web on which or on which a goods separator along the conveying path in the transport direction can be performed. For example, guide grooves are provided in opposite side bands of the goods delivery device, which are configured to receive one end of a goods separator. The goods issuing device, for example, automatically takes over a goods separator from the goods receiving device and guides it along the guide device as far as the receiving device, where the goods separator can be fixed.

It is alternatively or additionally also possible for a cashier to convey a goods separator manually into the guide device and from there along the guide device into the receiving device. In addition, it is preferably possible for the guide device to be able to guide it further in the transport direction into the packing zone after releasing the fixed goods separator.

In one embodiment of the goods dispensing device, the receiving device is arranged along the conveying path and arranged to fix a goods separator at different positions of the conveying path on the receiving device. Thus, the Nacherfassungszone can be flexibly adapted to the size or amount of goods of a shopping cart.

In a further embodiment of the checkout system, the goods issue device comprises a motorized transport device which is designed to transport a released goods separator back from the goods issue device to the goods receiving device. When a customer has finished packing his goods, he can deliver the goods separator to the motorized transport. The motorized transport then conveys the article divider back to the goods receiving device so that the article divider can be made available to another customer.

In a preferred embodiment of the cashier system, the goods detection device is designed to detect a goods separator as such. For this purpose, a goods separator, for example, a bar code, such as a QR code, or any other machine readable character. Thus, the goods-detecting device can recognize that goods of another shopping cart are to be registered. For example, upon detection of a goods separator, the product detection device may complete a current product registration process for a first customer and begin a new product registration process for a second customer.

The goods detection device comprises, for example, a so-called tunnel scanner. In this variant, the goods detection device has a scanner, which is arranged above the goods receiving device, so that goods can be transported below the scanner from the goods receiving device to the goods issuing device. The tunnel scanner is arranged, for example, like a bridge over a conveyor belt of the goods receiving device.

The checkout system of the first aspect of the invention may be configured, for example, as a self-checkout terminal.

a schematic and exemplary representation of a method according to the second aspect of the invention.

Fig. 1 shows schematically and by way of example a cashier system 100 in the form of a checkout terminal on which a customer 320 his (in the Fig. 1 not shown) goods can pay.

On the input side, the cashier system 100 has a goods receiving device 120 which accepts goods from the customer 320 and conveys them on a conveyor belt 122 in a transport direction T to a goods detection direction 140.

In the example shown, the goods detection device 140 is designed as a tunnel scanner.

For the delimitation of goods belonging to the conveyor belt 122 from different customers, a plurality of goods separators 210-1 to 210-6 are provided, of which some are stored in a memory 124 of the goods receiving device 120. The goods separators 210-1 to 210-6 are each provided with a (in the Fig. 1 to 8 not shown) bar code, such as a QR code, or provided any other machine-readable character, so that the goods detection device 140 can not only register goods, but also can detect the passage of a goods separator. Currently not used item separators 210-2 to 210-5 are located in a designated memory 124 of the goods receiving device 120th

The goods placed on the goods receiving device 120 are registered by the goods detecting device 140 (at least for the most part).

At a transition 150, a goods dispenser 160 is provided, which is downstream of the goods receiving device 120 and coupled to this barrier-free.

The goods dispensing device 160 has a sloping roller field 172, which is designed for transporting goods and goods separators 210-1 to 210-6 along a conveying path 166, 168 in the transport direction T. Alternatively, a motorized conveyor belt may be provided for the transport of goods and goods separators 210-1 to 210-6.

The goods issuing apparatus 160 picks up the goods conveyed from the goods receiving device 120 to the transfer 150, and goods separators 210-1 to 210-6, and further transports them to an end portion (right portion of the reel box) of the goods issuing apparatus 160. Acquisition of goods and goods separators 210-1 to 210-6 can either be done automatically or by manual help, for example by a cashier 310.

Furthermore, the goods issue device 160 has a preferably electrically controllable receiving device 162. The goods issuing device 160 takes over a goods separator 210-1 conveyed by the goods receiving device 120 up to the transition 150 and fixes the acquired product separator 210-1 after transport to the receiving device 162, for example, as in FIG Fig. 1 shown by mechanically capturing the approaching article divider 210-1. The goods separator 210-1 is fixed there for a certain time. The goods separator 210 - 1 fixed to the receiving device 162 divides the conveyor line 166, 168 of the goods issue device 160 into a read-detection zone 166 and into a packing zone 168.

The retrieval zone 166 is used to temporarily store goods of a shopping cart so that, if appropriate, goods that have not been registered by the goods detection device 140 (for example, because a product label to be scanned is damaged or illegible), by the cashier 310 or by the customer 320 can be retraced. The cashier 310 or the customer 320 should therefore be able to check there, whether all goods have been fully and correctly registered.

The receiving device 162 is formed for example in the form of two L-shaped closures with two arms 162-1, 162-2, of which in each case an arm 162-1 is movably mounted in the manner schematically illustrated. By opening and closing the receiving device 162 can be done so fixing or releasing the goods separator 210-1.

As soon as all the goods of a customer 320 have been completely read by the cashier 310, the goods separator 210-1 fixed to the receiving device 162 is released, for example by actuating the in Fig. 1 schematically shown folding mechanism '.

After release of the goods separator 210-1 this closes with the goods towards an end region of the goods issuing device 160.

The following Fig. 2 to 8 show the cashier system 100 during various stages of customer handling.

Fig. 2 shows that a first customer 320 puts his goods 200 on the conveyor 122 of the goods receiving device 120. The goods 200 are transported by the conveyor belt 122 in the direction of the goods issue device 160 and registered in this way by the goods detection device 140 in the form of a tunnel scanner.

In Fig. 3 It is shown that the goods 200 are taken over by the goods issuing device 160 at the transition 150 and are first collected by the goods separator 210-1 fixed to the receiving device 162 in the re-registration zone 166 of the goods issuing device 160. Thus, the cashier 310 may manually retrieve goods that may not have been detected by the goods detection device 140, such as by use of a handheld scanner.

Once the first customer 320 has placed all his goods 200 on the conveyor belt 122, this positions, as usual, a goods separator 210-6 to delimit his goods 200 from other goods on the conveyor belt 122 (s. Fig. 4 ).

A second customer 322 then places his goods 202 on the conveyor 122 for registration. Fig. 5 and 6 ). At the same time, the goods 200 of the first customer 320 in the re-capture zone 166 are collected by the fixed merchandise divider 210-1. The goods 200 that are uniquely associated with the merchandise divider 210-1 on the one hand and the merchandise divider 210-6 on the other hand with the first customer 320 may be subsequently tracked by the cashier 310.

The goods 202 of the second customer 322 and the goods separator 210-6 are transported by the conveyor belt 122 to the goods dispenser 160, that is in the transport direction T. Due to the fact that the goods issue device 160 also takes over the goods separator 210-6 at the transition 150, the goods of different customers always remain clearly separated from one another.

In Fig. 7 It is shown that the goods divider 210-1 has been released by the receiving device 162 and has been transported together with the goods 200 of the first customer 320 into an end region of the packing zone 168 of the goods issuing device 160. Now, the goods 202 of the second customer 322 are stowed by the product separator 210-6 fixed to the receiver 162, so that the cashier 310 can again detect any goods 202 not registered by the goods detecting device 140. It is also shown that the second customer 322 again delimits the content of his basket of goods by another item separator 210-5 of goods from other customers.

Fig. 8 FIG. 12 shows how the variable volume packs 168 are formed by the goods dispenser 160 in the packing zone 168, separated by the product separators 210-6 and 210-5. The first customer 320 may remove his goods 200 from the package tray bounded by the item separator 210-6 on the one hand and a right side panel of the item dispenser 160 on the other. A goods separator 210-1, which is no longer required, is conveyed back to the storage 124 of the goods receiving device 120 by a dedicated motorized transport 170 of the goods issuing device 160.

A second differently sized second outer containment package 202 of the second customer 322 is formed between the article divider 210-6 and the article divider 210-5 affixed to the receiver 162 such that the second customer 322 unimproved its article 202 from the merchandise packaging device 168 160, meanwhile goods 204 of a third customer 324 gather in the re-capture area 166.

The goods 204 of the third customer 324 are in turn clearly delimited by the goods separator 210-5 fixed to the receiving device 162 and by the goods separator 210-4 of goods 206 of a fourth customer 326 so that the cashier 310 receives the goods 204 of the product third party, if necessary, ie unless the goods detection device 140 has not automatically registered all the goods 204.

Meanwhile, the fourth customer 326 can lay undisturbed his goods 206 on the conveyor belt 122 of the goods receiving device 120, without having to fear that his goods 206 with goods 204, 202, 200 of other customers 324, 322, 320 get confused.

Of course, the goods dispensing device 160 in principle also significantly longer than in the Fig. 1 to 8 shown configured so that a plurality of customers 320, 322, 324 at the same time their goods 200, 202, 204 can be seen from their respective packing troughs. In this case, the packing troughs with the removal of the goods 200, 202, 204 by the Nachrutschen (in the case of a sloping role field 172) or by the Nachbefördern (in the case of a motorized conveyor belt) of subsequent goods 206 and goods separators 210-4 in size on. Thus, the entire conveyor line 166, 168 of the goods dispenser 160 is efficiently utilized.

Fig. 9 shows by way of example and schematically a method for operating a example in the Fig. 1 to 8 illustrated cashier system 100, which can be summarized as follows:

First, goods 200 are accepted by the goods receiving device 120 of the cashier system 100 (step 410). The accepted goods 200 are then registered by the goods detecting device 140 of the goods receiving device 120 (step 420).

Thereafter, takeover of registered goods 200 of the goods receiving device 120 and transportation of the registered goods 200 along the conveying path 166, 168 in the transport direction T by means of the goods issuing device 120 (step 430).

In step 440, the article divider 210-1 is fixed to the receiver 162 of the goods dispenser 160 to divide the conveyor line 166, 168 into a retrieval zone 166 for retrieving goods 200 and into a packing zone 168 for retrieving goods 200.

In response to a control command, a release (step 450) of the product separator 210-1 fixed to the receiving device 162 takes place. During the last step 460 of the in Fig. 9 In accordance with the method 400, the released product separator 210-1 is conveyed along the conveying path 166, 168 of the goods dispenser 160 into the packing zone in order to form variable-size packing containers. <B> LIST OF REFERENCES </ b> 100 Payment system 120 Goods acceptor 122 conveyor belt 124 Storage for goods separators 140 Goods detection device, eg in the form of a tunnel scanner 150 crossing 160 Goods dispensing apparatus 162 admission 166, 168 conveyor line 166 Nacherfassungszone 168 Pack zone 170 Motorized transport device 172 role field 200 Goods of a first customer 202 Goods of a second customer 204 Goods of a third customer 206 Goods of a fourth customer 210-1, ..., 210-6 dividers T transport direction 310 cashier 320 First customer 322 Second customer 324 Third customer 326 Fourth customer 400 Operating procedure for a cashier system 410 Acceptance of goods by a goods receiving device of the cashier system 420 Registering accepted goods by a goods detection device of the goods receiving device 430 Taking over registered goods of the goods receiving device and conveying the registered goods along a conveyor line by means of a goods receiving device downstream goods issue device of the cashier system 440 Fixing a goods separator on a receiving device of the goods issuing device to divide the conveyor line in a Nacherfassungszone for retrieval of goods and in a packing zone for removing goods 450 Releasing the product separator fixed on the receiving device to a control command 460 Transporting the released goods separator along the conveying path of the goods issuing device
