Description

[0001] The invention relates to a checkout counter for cashing goods in a shop, comprising a checkout body and a conveyor device arranged on the checkout body, which conveyor device essentially consists of a conveyor belt and a conveyor belt frame.

[0002] Checkout counters for cashing up goods in a store, and in particular those checkout counters that have both a conventional operator checkout and a self-service checkout, are generally known, for example from the prior art of DE 20 2020 104 539 U1. The checkout counter described therein has both a conventional operator checkout and a self-service checkout. The design in DE 20 2020 104 539 U1 is chosen such that the operator checkout, as usual, has a goods conveyor belt and a payment device at the head, with the self-service checkout being located at the rear on a privacy screen provided on the goods conveyor. In this case, the main goods conveyor belt is static relative to the overall checkout counter body and is thus spatially separated from the self-service checkouts. In this case, the two systems coexist, with the conventional operator checkout being deactivated when not in use.

[0003] The generic EP 2 266 443 B1 takes a different approach. The cash register described there is also a hybrid cash register, which offers the option of quickly switching between normal assisted use with a cashier and use as a self-service checkout. For this purpose, EP 2 266 443 B1 works with a movable end shelf. This is equipped with elements with the help of which the aforementioned end shelf can be adjusted from one position to another by rotating, pivoting and / or sliding. In this way, the teaching therein switches between normal assisted use and use as a self-service checkout. Rotating or pivoting the end shelf from one position to the other ultimately ensures that the customer can ultimately use the additional space as packing space when using the cash register system as a self-service checkout.

[0004] The state of the art has proven itself in principle, but offers potential for improvement with regard to efficient space utilization for hybrid checkout systems. When converting or using a conventional checkout system together with self-service checkouts, the current state of the art generally involves continuing to use the conveyor belt of the conventional checkout or, alternatively, simply leaving it unused. This hampers the space-efficient use of a checkout counter. The invention aims to remedy this situation.

[0005] The invention is based on the technical problem of further developing such a checkout counter for cashing goods in a store in such a way that, compared to the prior art, a checkout counter is provided which makes it particularly easy and space-saving to use the checkout counter either in the conventional manner or as a self-service checkout.

[0006] To solve this technical problem, the invention proposes, starting from a generic cash desk, that the conveyor belt frame together with the conveyor belt guided along it is designed to be movable relative to the cash register body.

[0007] The relative movement between the conveyor belt frame, together with the conveyor belt guided along it, and the checkout body can be horizontal, rotary, or a combination thereof. This means, for example, that a horizontal sliding movement of the conveyor belt frame relative to the checkout body is just as possible as its rotational or pivoting movement relative to the checkout body. Combined sliding and pivoting movements are also included. According to the invention, the conveyor belt frame is surrounded by an at least partially closed belt housing. The checkout body is generally understood to be a stationary structure located below the belt housing.

[0008] The relative movement of the conveyor belt frame together with the conveyor belt guided along it preferably takes place by means of at least one, preferably electric, drive. The drive is preferably designed as a linear drive. In principle, a rotary drive is also conceivable. The linear drive (or rotary drive) can, for example, be actuated by at least one electric motor. A gear unit connected upstream or downstream of the electric motor is also conceivable. Manual actuation of the linear drive is of course also possible. The conveyor belt frame preferably has at least one linear drive at each end. The contact point or connection point K defining the contact between the conveyor belt frame and the linear drive is preferably located on the side of the conveyor belt frame opposite an aisle.Additional drive units such as a worm drive or similar to actuate the linear drive are also conceivable.

[0009] Preferably, at least one display unit and / or a self-service checkout unit is arranged on the underside of the conveyor belt frame.

[0010] Preferably, the elements arranged on the underside are firmly connected to the conveyor belt frame.

[0011] Preferably, the conveyor belt frame has a belt box on the underside facing the cash register body that at least partially surrounds the conveyor belt frame. This box can accordingly be designed to be at least partially closed.

[0012] In a preferred embodiment, the conveyor belt frame has at least one display unit and / or a self-service checkout unit on the underside facing the checkout body, preferably in a recess in the belt box. The display unit can be a screen or touchscreen, for example. The elements arranged in the recess are preferably firmly connected to the belt box and / or the conveyor belt frame. This can be done, for example, by means of a simple screw connection. The elements connected to the belt box and / or conveyor belt frame in the recess are therefore moved equally relative to the checkout body if the conveyor belt frame is moved by the drive.

[0013] Control units such as cameras or other sensor devices are also conceivable. An example application would be surveillance cameras located above the display unit, monitoring an area assigned to the self-service checkout unit. Other sensors or control mechanisms are also conceivable. With the help of the sensors or control units, it can be monitored and ensured that the movement of the conveyor belt frame including the conveyor belt only occurs when no people are nearby and that collisions caused by this can be ruled out. The elements attached to the conveyor belt frame or belt box can of course also be attached to the underside or lower run side of a conveyor belt frame or belt box without a recess in order to achieve the advantages mentioned above.

[0014] Preferably, the conveyor belt frame has - in addition to the end rollers customary on a conveyor belt - at least one further roller mounted in the conveyor belt frame which acts on the conveyor belt. This additional roller is designed in particular as a deflection roller for the conveyor belt. Preferably, this additional deflection roller is indented in the conveyor belt frame in the direction of the outwardly visible conveyor belt such that the underside part of the conveyor belt is deflected inwards by the deflection roller. The above-mentioned end rollers customary on a conveyor belt can be designed either individually or together as drive rollers for the conveyor belt. For this purpose, for example, a preferably electric drive can be connected to at least one roller. The above-mentioned additional deflection roller generally does not have a drive function, but this is not excluded.

[0015] The preferred and advantageous deflection of the conveyor belt, as mentioned above, preferably allows for a particularly deep recess in the belt box. A recess that extends as far inward as possible, in turn, advantageously ensures that any elements mounted there can be installed in a particularly space-saving manner. Other space-saving options with regard to the conveyor belt frame to enable such a recess are also conceivable.

[0016] Preferably, the conveyor belt frame, together with the conveyor belt guided along it, is mounted on the checkout body so as to be rotatable about a rotation point or a rotation axis R. The rotation point is preferably located approximately centrally in the conveyor belt frame when viewed from the side. In particular, the rotation point or the rotation axis R is selected so that the conveyor belt frame is evenly balanced. A balanced weight distribution is particularly advantageous for the handling of the conveyor belt frame. This enables smooth rotation by the previously mentioned linear drives or the at least one linear drive, so that manual movement of the conveyor belt frame is also easily possible if necessary. The conveyor belt frame can be mounted on the checkout body using a ball bearing, for example. The bearing is preferably located at the end of the conveyor belt frame.

[0017] The contact point or connection point K between the drive or linear drive and the conveyor belt frame, as well as the rotation point or rotation axis R, preferably do not coincide in a side view, but are spaced apart from each other. This separation of the points defined in the side view ensures a possible rotational movement around the rotation point R of the conveyor belt frame. The effective lever arm is determined by the distance between contact point K and rotation point R and can thus be varied as desired within the limits defined by the conveyor belt frame and, particularly preferably, maximized. Accordingly, the contact point K is preferably located as far outside as possible on the conveyor belt frame to maximize the leverage.

[0018] In a further preferred embodiment, the conveyor belt frame, together with the conveyor belt guided along it, is designed to be movable in the horizontal direction, preferably orthogonal to the conveyor belt direction. For this purpose, the conveyor belt frame can, for example, have at least one guide rail which engages in a corresponding receptacle provided on the checkout body in order to enable precise guidance and smooth movement of the conveyor belt frame. In this embodiment, the checkout body preferably has a receptacle or recess for the conveyor belt frame inserted therein or for the conveyor belt frame including the belt box, so that the conveyor belt frame, when pushed in, completely opens access to the area located below the belt box or the conveyor belt frame.In a preferred embodiment, the sales shelf located next to the checkout counter has a corresponding hollow space for accommodating the belt box or the conveyor belt frame.

[0019] The conveyor belt frame and / or the checkout body preferably has at least one sensor device. The sensor device can, for example, be located in an electric motor driving a linear drive and be designed as a resistance sensor. It is thus conceivable that the electric current applied to the electric motor could be used to measure any resistance that must be overcome during the relative movement of the conveyor belt frame relative to the checkout body. If this resistance, and thus the current consumption, exceeds a predetermined value, this is interpreted, for example, as a piece of clothing or similarly an operator being trapped, and in the example case, leads to the shutdown and reversal of the drive.

[0020] Alternatively or additionally, sensors such as a light barrier formed between the conveyor belt frame and the cash register body are also conceivable. The sensor device is preferably designed such that the position of the conveyor belt frame relative to the cash register body is known or measured in real time and can be evaluated, for example, by an additional control unit. For this purpose, the electric motor can be a stepper motor. In particular, a resistance sensor in, for example, an electric motor driving a linear drive can trigger a stop in the movement of the conveyor belt frame depending on a predetermined resistance.On the one hand, the sensor device provides an advantageous protective function, so that if, for example, a person's limb is caught between the conveyor belt frame and the cash register body, the movement of the conveyor belt frame is effectively stopped, thus preventing injuries. On the other hand, precise and controlled movement of the conveyor belt frame can be ensured.

[0021] The sensor device can preferably also be capable of transmitting the position of the conveyor belt frame relative to the checkout body to an external control unit in real time, so that automatic opening and closing can take place. For example, depending on the position and / or activity of a checkout unit located on the checkout body and operable by a cashier, a timer can be initiated by the control unit so that, for example, after this checkout unit has not been used for 10 minutes, the conveyor belt frame is automatically moved. This allows for particularly efficient switching between operation in the conventional sense and operation as a self-service checkout, achieved by moving the conveyor belt frame, without the necessary intervention by a cashier or operator.

[0022] Preferably, the checkout counter is equipped with a cashier-operated checkout unit, consisting of at least one screen, a data capture device, and a payment unit. Furthermore, the checkout unit can have a printer, in particular for printing receipts. The data capture device is preferably designed as a goods scanner.

[0023] Preferably, the checkout unit, which can be operated by a cashier, can be converted into self-service mode, for example by pivoting the screen and / or activating a switch. The pivoting of the screen can preferably be carried out via a stand attached to the screen. For example, the pivoting process can be completed by activating a contact sensor, so that the contact sensor is triggered as soon as the screen and stand have reached the final pivoted position. Particularly advantageously, pivoting the screen can also release and / or trigger the relative movement of the conveyor belt frame. Alternatively, pivoting the screen and, if applicable, activating the contact sensor can release another switch for activation. This switch is preferably positioned so that the cashier has a view of the aisle and the customers located there.The design is preferably such that the switch must be manually operated by the cashier, and only then is movement of the conveyor belt frame possible. This creates a multi-stage safety routine that prevents accidental relative movement of the conveyor belt frame.

[0024] In a preferred embodiment, the invention provides that, after the pivoting process has been completed, both the detection device and the payment unit, as well as the screen of the checkout unit, can be operated independently by the customer, thus eliminating the need for an additional operator. For this purpose, the checkout unit, which can be operated by a cashier, can be rotated toward the aisle side, for example, along with the elements essential for self-service of the checkout unit and the screen. This function can be performed independently of the movement of the conveyor belt frame or coupled to it.

[0025] The checkout body preferably has a longitudinal cavity in proximity to the conveyor belt frame, preferably with at least one self-service checkout unit located therein. The longitudinal cavity is preferably designed as a recess in the checkout body with lateral support surfaces provided for the conveyor belt frame. The self-service checkout unit preferably has at least one detection device and one payment unit. The self-service checkout unit can also include a display unit.

[0026] The checkout counter, and in particular the cash register body, preferably has at least one, preferably optical, guidance unit. The guidance unit can be configured, for example, as a screen and / or light source, which displays the status of the checkout units. This allows the customer to be clearly informed whether they should first place the goods on the conveyor belt for the cashier located at the cashier-operated checkout unit, or whether this checkout unit is in self-service mode. Additionally or alternatively, acoustic signals are also included, for example, via loudspeakers located on the cash register body.

[0027] The checkout counter preferably has a product divider holder with a profile for the product dividers accommodated therein. The product divider holder can preferably be rotated by an angle α starting from the conveyor belt plane. This ensures that the product dividers remain in the product divider holder when the conveyor belt frame rotates, for example, by 90°, regardless of any profiled product dividers.

[0028] Alternatively or additionally, the product divider holder can be designed, for example, as a profiled longitudinal rail running on the side of the conveyor belt frame opposite the aisle. The product dividers preferably have a positive-locking profile with the product divider holder so that they are guided in the product divider holder when inserted. The profiling can be a T-slot, for example, so that only horizontal movement of the product dividers in the conveying direction is permitted. The product dividers preferably have a spring holding mechanism which can be used, for example, to insert and / or remove the product dividers. In the case of a T-shaped groove, the T-wings of the product dividers can, for example, be designed to be foldable in and out using a spring mechanism so that the product dividers can be easily and effectively inserted into the product divider holder and held there.This profiling of the product separator holder, together with the positive profiling of the product separators, particularly advantageously ensures that the product separators are held in the product separator holder during the relative movement of the conveyor belt frame according to the invention, thus preventing the product separators from falling out.

[0029] The invention also includes a method for cashing out goods in a store at a checkout counter, comprising a checkout body and a conveyor device arranged on the checkout body, which consists essentially of a conveyor belt and a conveyor belt frame, which is characterized in that the conveyor belt frame is moved together with the conveyor belt guided along it relative to the checkout body.

[0030] The invention is explained in more detail below with reference to drawings which merely represent exemplary embodiments; in which: Fig. 1 the cash desk in a basic overview, Fig. 2 the cash desk of the Fig. 1 with folded-up belt box or conveyor belt frame, Fig. 3A to 3C the cashier unit located on the cash desk with a rotatable screen when the belt box or conveyor belt frame is folded down or up, Fig. 4A and Fig. 4B is a schematic representation of the mechanism located in the cash register body, Fig. 5A to 5C isolated representations of the band box and its interior and Fig. 6 an alternative embodiment in overview view with horizontally movable band box.

[0031] The figures show a checkout counter 1 for cashing out goods in a shop. In the embodiment shown here, the checkout counter consists of at least one checkout body 2, a cashier-operated cashier unit 3, and a conveyor device 4, 5, 6 consisting of a conveyor belt 4, a conveyor belt box 5 (which is also generally unnecessary), and a conveyor belt frame 6. The checkout counter 1 is designed such that the conveyor belt box 5 with the conveyor belt frame 6 located therein, as well as the conveyor belt 4 mounted on the conveyor belt frame 6 and moved along it, can be pivoted in order to Fig. 1 in “Normal Mode” cash desk 1 in the Fig. 2 shown “self-service mode”.

[0032] For this purpose, the cash register body 2 has a longitudinal cavity 7 located beneath the belt box 5. The longitudinal cavity 7 has at least one self-service checkout unit 8, and in this case, two self-service checkout units 8.

[0033] The respective self-service checkout unit 8 consists of a recording device 9, a payment unit 10 and a display unit 11, as can best be seen in the Fig. 2. In addition, the self-service checkout unit 8 can be equipped with a printer, in particular for printing receipts. The display unit 11, here in particular designed as a screen, is not located on the cash register body 2, unlike the detection device 9 and the payment unit 10, but rather the screen or the display unit 11 is attached to the underside of the belt box 5. The positioning of the self-service checkout unit 8 is selected in the longitudinal cavity 7 such that support surfaces 12 are provided to the left and right of the self-service checkout unit 8. Thus, the customer can Fig. 2. At the checkout counter 1 in "self-service mode," the purchaser first places the goods to be purchased to the left of the self-service checkout unit 8, then registers them using the registration device 9, and then places the already registered items on the support surface 12 located to the right of the self-service checkout unit 8. After the registration process has been completed, the screen 11 then displays the amount to be paid, which the user can pay via the payment unit 10. In addition to the two self-service checkout units 8, the checkout unit 3 already used in "normal mode" can also be used as a self-service checkout.

[0034] The procedure for transferring the checkout counter 1 from “normal mode” to “self-service mode” is described in the Fig. 3A to 3C are shown particularly from the perspective of a cashier. The checkout counter 1 with the cashier unit 3 in “normal mode” is shown in Fig. 3A. The checkout unit 3 has at least one screen 13, a cash register payment unit 14 and a cash register registration device 15. Furthermore, the checkout unit 3 is equipped with a printer 28, in particular for printing receipts. The screen 13 is pivotable and, in "normal mode," is oriented towards the cashier located at the checkout station 16. In the exemplary embodiment shown here, the pivotable screen 13 has a release function for a second actuating switch, preferably arranged in the cavity 7. The cashier can only actuate the actuating switch on the aisle side, so that a safety-relevant overview of the people in the aisle is necessarily provided. The actuation of the actuating switch subsequently enables the possible pivoting of the belt box 5 or the conveyor belt frame 6 together with the conveyor belt 4 guided thereon. If the screen 13 is in the position shown in the Fig. 3A, the operating switch located in the cavity 7 and consequently the swiveling of the belt box 5 are not possible. In order to transfer the checkout counter from the "normal mode" to the "self-service mode", as shown in the Fig. 3B, the screen 13 rotates such that it is rotated at least 90° counterclockwise from its position in the direction of the cashier. After reaching the pivoting position, the screen 13 triggers, for example, a contact sensor or proximity sensor, which in turn activates the actuating switch located in the cavity 7. This, on the one hand, releases the rotation path or pivoting path for the belt box 5 and, on the other hand, in this exemplary embodiment, a previously existing lock, preferably an electrical lock, is released so that the belt box 5 can subsequently be pivoted. Once the screen 13 has been pivoted and the actuating switch has been actuated and the associated lock or pivoting lock has been released, the belt box 5 can, as shown in the Fig. 3C, preferably by 90°. This two-switch configuration ensures a particularly safe and controlled triggering of the relative movement of the conveyor belt frame, thus preventing unwanted triggering of the movement.

[0035] In the case of the rotational movement of the belt box 5 or the conveyor device 4, 5, 6 located therein with the conveyor belt 4 guided along it for switching between "normal mode" and "self-service mode", the cash register body 2 has a support frame 17 located therein with linear drives 18 located thereon. The linear drives 18, which are each attached to the ends of the belt box 5 and to the support frame 17, are each driven by electric motors 19 attached to the support frame 17 (cf. Fig. 4A and Fig. 4B).

[0036] The belt box 5 or the conveyor belt frame 6 located in the belt box 5 is pivotably mounted on the support frame 17 located in the cash register body 2 at a rotation point or about a rotation axis R. This mounting is provided at each end of the conveyor belt frame 6. The respective linear drive 18 is mechanically coupled to the conveyor belt frame 6 at the connection point or contact point K. The rotation point R and the contact point K do not overlap, but are oriented at a distance from each other. The distance between the rotation point R and the contact point K influences, among other things, the drive power of the linear drive 18 required to trigger the rotational movement.Thus, by varying the distance between the rotation point R and the contact point K, the leverage, the force exerted by the linear drive 18 on the conveyor belt frame 6, and thus the torque, can be varied at least within the dimensions of the conveyor belt frame 6, for example, to ensure particularly smooth rotation of the conveyor belt frame 6. Preferably, and as shown in . Fig. As shown in Figure 4A, the contact point K is located as far outward within the band box 5 as possible in order to ensure a maximum lever arm between contact point K and the approximately central rotation axis or rotation point R.

[0037] After the rotation of the band box 5 has been completed, the rotation is preferably stopped after a rotation of 90°, as shown in the Fig. 4B. This can be achieved, for example, by a stop 20. The stop 20 can also ensure that the screens 11 attached to the conveyor box 5 and the self-service checkout units 8 are switched on or enabled, so that the checkout counter 1 is transferred to "self-service mode." In addition, the stop 20, which is equipped, for example, with a sensor, can ensure that the conveyor belt 4 is locked in "self-service mode," effectively preventing an unintentional triggering of a conveyor process.

[0038] The Fig. The illustration of the conveyor belt 4 shown in Figure 5A shows that the conveyor belt 4 is deflected at the bottom by a deflection roller 21 in the direction of the conveyor belt 4 running on the top. This is done by the Fig. 5A shows an upwardly offset deflection roller 21. In addition, the conveyor belt frame 6 can also have one or more spacers 23, which prevent any possible sagging of the conveyor belt. Alternatively, further deflection rollers 21 are conceivable. The conveyor belt frame 6 typically has rollers 22 mounted at the ends, one or both of which drive the conveyor belt 4. Due to one or more offset deflection rollers 21, the central section of the conveyor belt frame 6 has an inwardly directed free space. The aforementioned deflection of the conveyor belt 4 by means of the deflection rollers 21 enables, as shown in FIG. 5B, the belt box 5 to have a recess 24 in the area of ​​the previously mentioned free space. Fig. 5B shows the belt box 5 from a perspective view from above with the conveyor belt 4 hidden, so that the recess 24 made possible by the deflection rollers 21, which are also hidden, becomes visible.

[0039] On the conveyor box 5 there is also a product separator rail 25 with product separators 26 located therein. The product separator rail 25 extends in the longitudinal direction of the conveyor box 5, specifically facing the aisle. As can be seen from the Fig. 5B or the cross-sectional drawing therein, the product separator holder is rotated by an angle α starting from the conveyor belt plane. This ensures that even with a conventional cuboid-like shape of the product separators, they remain in the product separator holder when the conveyor belt frame rotates by, for example, 90°. Alternatively, a solution is shown in which the product separator rail 25 has a T-slot in cross-section. The product separators 26 also have a T-shaped shoulder that is positively connected to the T-slot of the product separator rail 25, so that the product separators 26 cannot fall out when the belt box 5 rotates, for example, to a 90° position.

[0040] The previously mentioned recess 24 in the band box 5 is in the Fig. 5C shown in perspective from below. The recess 24 advantageously ensures that the display units 11 arranged in the recess 24 can be mounted in the belt box 5 in a particularly space-saving manner and consequently do not protrude beyond the belt box 5. The display units 11 are preferably designed such that they are completely immersed in the recess 24, so that no protrusion is observed through the display units 11. In addition, the recess 24 offers the possibility of attaching additional hardware, such as video cameras or similar monitoring devices.

[0041] As an alternative to the embodiment shown in the previous figures, the Fig.6 shows an alternative embodiment with a horizontally displaceable belt box 5, specifically in the transverse direction compared to the conveyor belt 4 or a conveying direction of the goods. In this case, the display unit 11 is hingedly attached to the self-service checkout unit 8. Other embodiments, such as display units 11 attached to a rear sales shelf 27, are also conceivable. The sales shelf 27 opposite the aisle or the aisle side also has a hollow space into which the belt box 5 can move in a horizontally and transversely displaced state. For this purpose, the linear drives 18 are also arranged horizontally in order to thus act on the belt box 5 in the horizontal direction.In this case, the “self-service mode” corresponds to the state in which the belt box 5 has moved into the cavity located in the sales shelf 27 and the display units 11 are folded up, for example automatically, so that the self-service checkout units 8 can be operated independently by the user.
