Definitions
- the invention relates to a system for detecting and rewarding the return of a shopping trolley or luggage trolley removed from a collection point according to the preamble of claim 1 and a corresponding method according to the preamble of claim 25.
- the system comprises a number of shopping carts, each of which is provided with a contactlessly identifiable, individual identification, at least one collection point for the shopping carts and detection means arranged in the region of the collection point for the identification of the shopping carts, the detection means being designed in such a way that they generate a signal to issue a bonus when it detects a deferred shopping cart.
- hopping cart means not only a shopping cart in the narrower sense, but also a luggage cart or transport cart and the like.
- Self-service supermarkets are usually interested in customers using a shopping cart.
- the shopping carts are usually kept at collection points from which the customer can remove a cart and take it to the supermarket.
- experience shows that customers' motivation to return the used shopping cart to the collection point after the purchase has been made is very low. Instead, the shopping carts are often left where they were unloaded - usually in the middle of the parking lot of the purchase market. This creates additional costs for the shopping market, since personnel must be available to collect the abandoned shopping carts. In addition, there is always the risk of damage to parked vehicles and the like due to abandoned shopping carts.
- the shopping carts are often provided with deposit locks.
- the customer can only remove a shopping cart from the collection point if he sets a deposit coin or the like in the deposit lock. The coin will not be released until the shopping cart is properly returned to the collection point.
- the deposit lock system is also perceived by some customer groups as inadequate maintenance and over-regulation.
- each shopping cart is provided with an electronic transceiver device.
- the path of each shopping cart is tracked and saved using means of acquisition in the supermarket, in particular at the cash register, and at the collection points for the shopping carts.
- a central data processing device recognizes when a shopping cart has passed the cash register and has arrived at the collection point and then issues a bonus in the form of a voucher or a ticket to a lottery.
- the electronic transceiver devices that have to be attached to each shopping cart, however, cause considerable additional costs for the original equipment and a considerable maintenance effort due to the necessary mobile energy supply.
- shopping carts are often treated with little care, so that frequent malfunctions of this transceiver device must be expected.
- a problem with these contactless return systems is that it is unfavorable if the customers somehow put the shopping carts in the collection point and thereby already receive the bonus for returning the shopping cart. Instead, it should be ensured that customers place the shopping carts properly in the collection point, which generally means that the shopping cart is inserted into a row of shopping carts formed in the collection point.
- This problem has already been recognized in WO 01/82241; It has been proposed to program a digital camera in such a way that it recognizes the handlebars of the shopping trolleys and can report to the detection means whether the shopping cart which is to trigger a bonus has a handlebar within a predetermined tolerance within the handlebar row of the corresponding shopping cart stack row stands.
- the present invention is based on the object of further improving a shopping cart return system and a corresponding method of the type mentioned at the outset and, in particular, of recording the fact that the shopping cart has been properly returned to the collection point provided for this purpose as inexpensively and reliably as possible.
- the invention therefore differs from already known feedback systems in that the marking of the shopping cart transfers from an active state, in which the marking can be identified by the detection means, to a passive state, in which the marking is not identifiable by the detection means and / or vice versa, the labeling of the shopping trolleys can be transferred from the passive state to the active state, the transfer from the active to the passive state or from the passive to the active state expediently in connection with the returning of the shopping cart to a collection point he follows.
- This inventive design of the shopping cart markings enables the detection means, which can identify the individual marking of each shopping trolley, not only to detect the presence of each shopping trolley, but also by “switching” the marking (or also an adjacent marking). receive additional information from the active to the passive state or vice versa, because if the changeover from the active to the passive or from the passive to the active state is triggered by a process which is to be recognized by the detection means, these can not only detect the presence of a shopping cart , but also detect the course of this process and report or process it further.
- the process that leads to additional information can be, in particular, the proper return of a shopping cart to the collection point. It is then not sufficient to issue a bonus if the detection means recognize the presence of the shopping cart in or in the area of the collection point; Rather, the bonus is only issued or the signal for issuing the bonus is only generated when it is recognized by the detection means by switching a label from the active to the passive state or vice versa that the shopping cart has been properly placed in the collection point.
- the marking is preferably only switched over when the identified shopping cart is within a predetermined tolerance is set in a shopping cart stack row provided in the collection point. However, it is also conceivable that the switching of the marking is activated by other actions by the customer that are to be recognized by the detection means.
- the simplest way to implement the invention is if the labeling of the shopping carts is optically identifiable and the detection means are optical detection means. Coded character strings are primarily considered as optical identifiers, but other optical identifiers are also conceivable, as are already described per se in WO 01/82241.
- One embodiment of the system is that the identification of a single shopping cart that is not in a row of shopping trolleys is basically in its active state, which offers additional advantages in that the shopping carts can also be found outside the collection point, in particular in the supermarket or can be identified at the checkout using their identification.
- the marking can then change from its active (basic) state to the passive state in a first shopping cart as soon as a second shopping cart located behind the first shopping cart is pushed into the first shopping cart to form or continue a row of stacks.
- the marking can also change from its active (basic) state to the passive state in the case of a second shopping cart if the second shopping cart is inserted into a first shopping cart standing in front of it in order to form or continue a row of shopping trolleys. This is preferably done exactly when the shopping cart in question is properly set in the stack row.
- the switchover of the indicators means that only the last shopping cart in a row of shopping trolleys has an indicator in the active state. All other indicators of the shopping carts placed in front of him in the stack row are switched to passive.
- the detection means can comprise a camera for each row of stacks, which is arranged at the head end of the row of stacks and which, when viewed along the row of stacks, recognizes the identification of the last shopping cart.
- the detection means can comprise a camera for each row of stacks, which is arranged at the head end of the row of stacks and which, when viewed along the row of stacks, recognizes the identification of the last shopping cart.
- the corresponding tablet of the penultimate shopping cart is folded away, so that the camera now recognizes and identifies the tablet of the shopping cart that has just been set.
- the shopping cart that has just been reset is then only identified when it has been properly inserted into the stacking row until the license plate of the shopping cart in front of it has been brought into its inactive state.
- Such panels can be arranged on the bottom of the shopping trolley or can be attached to a foldable rear wall of the shopping trolley, which is usually already present anyway, whereby they are pivoted with it from an essentially vertical position into an essentially horizontal position when another shopping trolley is inserted.
- the invention can also be implemented in such a way that the labeling of the shopping trolleys is basically in its passive state when it is isolated, that is to say not in a row of shopping trolleys.
- the identification of a second shopping cart then changes to its active state when this second shopping cart is pushed into a first shopping cart standing in front of it.
- the detection means can always identify only the last shopping cart standing in a shopping cart stack row, since only this one has an identification in the active state, this identification being precise then occurs when the shopping cart in question has been properly placed in the stacking row.
- the status of the marking of a shopping cart that is not empty always remains constant, that is to say remains passive in the present case. This prevents any manipulation attempts in which the customer drives the shopping cart that has not yet been unloaded to the collection point, picks up the bonus, and then unloads the shopping cart, after which he can then confidently leave it there.
- the identification of a second shopping cart changes from its passive (basic) state to its active state when this second shopping cart is inserted into a first shopping cart standing in front of it, but then switches back to its passive state when a third shopping cart located behind the second shopping cart is pushed into the second shopping cart.
- an activation device in order to ensure the function of the system for the first shopping trolley in each row of stacks, an activation device can advantageously be provided at the collection point, which changes the state of the identification of a very first shopping trolley, as if it had been inserted into a shopping trolley in front of it would have been.
- each shopping cart can be recorded by means of registration that work with different orientations.
- contactless electronic identification in particular a transponder on the shopping cart. It is only important that the transponder can be converted from an active to a passive state and vice versa. This can be done not only electronically, but also purely mechanically, namely by pivoting the transponder when inserting the shopping cart into a stack, for example, so that it comes to rest in a shielding metal housing, or simply changing its orientation and thus no longer recognized for the detection means or recognized as being “incorrectly” oriented.
- the recording means are designed in such a way that they recognize when a collection point is fully occupied and when a collection point is empty. It is common to observe that customers who park their vehicles in a parking lot that is further away from the supermarket take their shopping trolleys from a collection point near the supermarket, but do not return them there after shopping, but the collection point closest to the vehicle to use. As a result, entire rows of shopping trolleys and stacks of shopping trolleys have to be moved from remote collection points to the collection points located near the shopping market at regular intervals with corresponding personnel expenditure.
- the detection means can now decide that a shopping cart is placed in a collection point which is already recognized as fully occupied or is additionally placed in a stack row there, the issuance of a bonus can accordingly be refused.
- each collection point is provided with display elements that are connected to the data acquisition means for data exchange and that are If you can acceptably indicate whether a collection point is empty and / or fully occupied, customers may be able to see from afar that they have to use another collection point in order to receive a bonus. If the recording means of the individual collection points are connected to one another for data exchange, a type of control system can even be implemented, the display elements pointing the customer to the nearest collection point that is not yet fully occupied.
- the cameras already mentioned as part of the detection means according to the invention can be designed with a microprocessor and one or more image recognition sensors, for example as CCD or CMOS cameras.
- the lenses can have electrically adjustable focal lengths.
- several image sensors can also be used, each of which is equipped with its own lens with different but fixed focal lengths.
- the observation area can be divided into several detection areas, in particular distance areas. This has the advantage that lenses with poor imaging properties and image sensors with low light sensitivity can be used.
- there is no need for a control and movement mechanism for the focus of the lens which could cause problems, especially at low temperatures.
- the detection means can be provided with lighting means. This can be done, for example, with light-emitting diodes, possibly in the infrared range.
- the lighting means or the cameras can be triggered by a motion detector, so that the lighting and / or the camera is only put into operation when a shopping cart is actually placed in the collection point.
- the lighting means can also be operated in flash mode, which further reduces the energy requirement.
- the detection means can be constructed in a modular manner, preferably with a central module, with camera modules and optionally with lighting modules.
- the central module monitors all connected modules, can control them and exchange information.
- the central module also controls, in particular, using the data recorded by the camera modules Reading and writing devices for a customer's data carrier in order to credit the customer with a bonus.
- the central module can also control a printer, which then issues a printed bonus credit.
- the central module is then preferably near the entrance to the assembly point.
- a motion detector could also be located there, with the aid of which the central module controls the camera modules and, if appropriate, the lighting module.
- the corresponding modules for energy saving can be switched off or put into a sleep mode if nobody is near the collection point.
- the central module can also operate an acoustic and / or visual display unit in order to display information to the customer, for example about the possibility of receiving a bonus for the return of the shopping cart, the successful allocation of the bonus or its value.
- Other information can also be displayed, such as the number of shopping carts present in the collection point, the fact that the collection point is empty or that it can no longer accommodate further shopping carts, so that no bonus is given for additional shopping carts.
- This information can preferably be displayed from afar, for example by means of a display device on the roof of the collection point.
- a power supply module can be present, which is designed as a power supply unit at collection points that can be connected to the power grid and otherwise consists, for example, of a solar energy module.

- FIG. 10 shows a collection point with several shopping trolleys of a fourth embodiment.
- Figure 1 shows a collection point 10 for similar shopping trolleys 11, 12, 13, 14, 15 of a supermarket.
- the collection point 10 is formed in a known manner as a shelter with a roof 40 which is supported by supports 42.
- the collection point 10 has a rectangular plan.
- the collection point 10 is delimited on three sides by elements, not shown, so that the station 10 is only accessible through an entrance.
- the shopping carts 12, 13, 15 are properly parked in the collection point.
- the shopping cart 11 is being returned to the collection point 10, but has not yet been parked properly.
- the shopping cart 14 is located outside the collection point 10.
- a camera module 62 is attached, the direction of which shows the entrance.
- the shopping carts 11, 12, 13, 14, 15 are of identical design.
- the different reference symbols for the individual shopping carts are mainly used in the following in order to be able to specify their position within a plurality of shopping carts.
- the direction of travel of the shopping cart is defined as the direction in which the shopping cart moves when the user holds the shopping cart by the handle and pushes it in front of him.
- FIGS. 1, 2 The direction of travel of the shopping trolleys in FIGS. 1, 2 is accordingly and 4 from left to right and in Figures 6 to 10 from right to left.
- the illustration in FIG. 3 shows the shopping cart moving towards the viewer.
- the shopping cart in FIG. 2 has a frame 18 which can be moved on rollers 16.
- a push handle 20 and a basket 24 are attached to the frame 18.
- a rear end of the shopping cart 14 is defined by the push handle 20.
- the basket 24 delimits the loading space and consists of two side walls 28, a front end wall 27, a floor 30 and a rear rear wall 29.
- the rear rear wall 29 is designed in a known manner as a flap which can be pivoted about a horizontal axis S, as a result of which one is pushed into one another the shopping cart 1 1, 12, 13, 14, 15 is possible in a known manner. Pushing one another results in a high packing density of the properly parked shopping trolleys 12, 13, 15 in the collection point 10.
- a plate 32 is provided on the shopping cart as an identification mark, which in the example shown is pivotally attached to the bottom 30 of the basket 24.
- An individual identification 36 is attached to the board 32.
- the board 32 can be changed from a first, active state, in which the marking 36 is clearly visible, to a second, passive state, in which the marking 36 is not visible.
- the panel 32 is pivotally attached to the underside of the basket 24 and hangs essentially vertically downward in the active state.
- the board 32 lies almost horizontally on the bottom 30 of the basket 24.
- the panel 32 protrudes beyond the silhouette of the basket 24 in the active state.
- the marking 36 on the board 32 is clearly visible in the active state, in particular from directly or slightly obliquely at the front, even if there are further shopping carts in front of the shopping cart, the boards 32 of which have assumed the passive state.
- FIG. 3 shows the shopping cart viewed from the front, as already explained above.
- Panel 32 is in the active state.
- the marking 36 is implemented in the form of a four-line bar code.
- the barcode can represent any alphanumeric characters. that can be used to clearly identify the shopping cart.
- other markings are also conceivable, for example symbols or two-dimensional point or bar codes as are known in large numbers for the image recognition method.
- transponders or resonators which can be changed from an active state in which they emit or send signals back to a passive state in which they do not Send or send signals back.
- each shopping cart is preferably unique, so that each shopping cart is clearly identifiable.
- Panel 32 and 32a have a different position. Panel 32 is in the passive state and panel 32a is in the active state. The last shopping cart in the row is shopping cart 11.
- the board 32 on the shopping cart is folded away when the shopping cart is completely pushed into the other shopping cart.
- the shopping carts 12, 13, 15 have already been completely pushed into one another, the panels 32 attached to this shopping cart have been folded away and are not recognized by the camera 62. Because the panels 32 are folded away, they give a clear view of the panel 32a attached to the shopping cart 11.
- the view from the camera module 62 onto the marking 36 of the shopping cart 11 attached to the board 32a is then not obstructed by any other parts of the shopping carts in front of it.
- the panel 32a attached to it is also folded away and the marking on it is no longer visible to the camera 62.
- This change from a state in which a marking is visible in another state in which no marking is visible can be interpreted as an indicator for a correct setting of the shopping cart 11. Depending on this, a bonus can be issued to those who have properly placed the shopping cart.
- the first shopping cart 13, which is placed in a collection point 10, has no predecessor into which it can be inserted.
- An activation device 56 is provided so that the board 32 of this shopping cart 13 can nevertheless be brought into the passive state.
- the collection point 10 is shown in the direction of the entrance of the collection point 10.
- the collection point 10 is provided for receiving two rows of shopping carts. In the example shown there are only 50 shopping trolleys in the left row. There are no shopping trolleys in the right row.
- the two rows are separated from one another by guide rails 54; at the same time, the guide rails 54 ensure a straight-line arrangement of the shopping trolleys in the row 50.
- a traverse 44 is attached to the end of the rows.
- a camera module 62 is visible in the area of the right row.
- Another camera module is also located at the end of the left row, but is covered by the flap 32 in this view.
- Each camera module 62 is equipped with at least one image sensor 64 and one lighting module 66.
- the camera modules 62 are aligned in such a way that they can detect the mark 36 on the hanging panels 32 under the baskets 30 of the shopping trolleys 11, 12, 13, 14, 15 along the rows of wagons assigned to them.
- the camera modules 62 are preferably mounted such that they are horizontally and vertically aligned with the hanging panels 32 of the shopping trolleys in the respective row.
- the image sensors 64 can detect the image of the marking 36 with the least possible distortions.
- three image sensors 64a, 64b and 64c are provided in the camera module 62 shown, each of which is equipped with a different lens, see above that each of the image sensors 64 covers a different angle and a different range.
- the viewing angle of the first image sensor 64a is preferably selected such that it just barely completely detects the marking 36 on an active board 32 of a shopping cart when this shopping cart is in the position due to the structure of the Collection point 10 predetermined, shortest distance to the first image sensor 64a.
- the maximum range of the first image sensor 64a is then given by the distance at which the image of a marking 36 is still so large that it can still be resolved by this image sensor 64a. This maximum permissible distance is limited by the resolution of the image sensor 64a but also by the focus range and the quality of the optics.
- the viewing angle of the second image sensor 64b is in turn selected such that it just barely completely captures a marking 36 at the maximum permissible distance for the first image sensor, taking into account the tolerances already mentioned.
- the maximum permissible distance of a marking 36 in the second image sensor 64b is in turn limited by the same conditions as in the first image sensor 64a. From this distance, the marking 36 is detected by the third image sensor 64c.
- the distance ranges mentioned are coordinated with one another in such a way that they overlap slightly in order to ensure reliable detection.
- the image sensor that delivers the best image is selected for acquisition.
- a control unit contained in the camera module such as a microcontroller, can successively read out the images of the three image sensors and check for an image content that can be evaluated.
- the microcontroller can preferably start with the camera module last delivered an evaluable image, since it can be assumed that the following image also comes from this image sensor:
- the camera modules 62 are also equipped with lighting modules 66 for illuminating the panels 32, for example in the form of one or more IR-LED arrays, which, if necessary, can preferably be switched on briefly when a panel 32 is detected.
- Additional lighting modules can optionally be provided along the row 50, which can be attached, for example, to a lateral cross strut in order to be able to adequately illuminate the panels 32 of shopping trolleys standing further ahead.
- a central module 68 is attached to the support 42 at the input 48 and is connected to the camera modules 62.
- the central module 68 also has a read and write device 70 for customer data carriers and one or more output units 72, e.g. Display, signal lamp, loudspeaker or voucher printer.
- a read and write device 70 for customer data carriers and one or more output units 72, e.g. Display, signal lamp, loudspeaker or voucher printer.
- a display module 74 is attached above each shopping cart row, which can show the customer information about the occupancy status of the respective row.
- the display modules 74 are connected to the central module 68 and are controlled by it.
- the central module 68 has all the information relating to the inserted and removed wagons and can use the display module 74 to display, for example, “empty” if there are no more wagons available in the respective row, or “stop” if the row is full and for further wagons Wagons therefore no bonus is given anymore.
- the central module 68 has stored a list of the numbers of the shopping carts 12, 13, 15 currently stored in its collection point 10. With the help of this list it is possible to see whether a shopping cart has been returned or removed. For this purpose, the central module 68 compares the currently recognized number with the numbers stored in the list. If the currently recognized number is in the list, this means that the shopping cart with this number has been removed from the row, this number is then deleted from the list. If the number is not in the list, the shopping cart has been added to the row. The number of the new shopping cart is added to the list and a bonus can be given.
- the identification indicator is set to the passive state again when the newly added shopping cart is completely and correctly inserted. This is done by pivoting the panel 32 horizontally. It can be provided that the bonus is only issued when the change from the active state to the passive state is recognized.
- the detection means can also be used to determine the size of the marking 36 on the respective image sensors 64a, 64b, 64c and to infer the distance between the shopping cart and the camera module 62. On the one hand, this makes it possible to infer the number of shopping carts 12, 13, 15 in this row.
- This information can be used, for example, to limit the length of row 50, by optionally indicating to the customer via the display module 74 above the row in question that shopping trolleys can no longer be inserted in this row 50 and / or for shopping trolleys no bonus is given in this row 50.
- the shopping cart 11 can be used to assess whether, for example, the shopping cart 11 has actually been parked properly, ie whether it has been completely pushed into the shopping cart 15 in front of it.
- the distance in which the marking 36 of the shopping cart 15 was detected can be stored in the central module 68. Then it can be checked whether the newly added My shopping cart 11 is close enough, ie - within a tolerance range - at an expected distance.
- the advantage of this embodiment is that a shopping cart 11 can already be recognized as soon as it is in the corresponding row 50 in the detection area of the camera module, specifically before it is inserted into the last shopping cart 15 of the row 50. Through dynamic evaluation of the change in size of the image of the marking 36, it can also be registered whether the shopping cart 11 is moving towards the row 50 or is moving away from it, i.e. whether it is discontinued or withdrawn.
- FIGS. 6 and 7 show a second embodiment of the invention.
- the status of the identification of the respective shopping cart is not changed when it is inserted into a shopping cart in front of it, but only when a subsequent shopping cart is inserted.
- the identification of the last shopping cart 15 of a row is always in the active state and is only put into a passive state by the insertion of the following shopping cart 11.
- Appropriate mechanical measures are used to switch to the other state only when the next shopping cart 11 has been completely pushed into the shopping cart 15 standing in front of it. Only from this point in time can another newly added shopping cart be recognized. If the returned shopping cart 11 is not properly inserted into the previous shopping cart 15, it cannot be recognized and no bonus is issued. This has the positive effect that a person who brings back the shopping cart 11 ensures that all shopping carts in the row are pushed properly into one another. This ensures that the shopping cart always has a high packing density.
- a driver pin 82 is provided on the board 32, which protrudes through the bottom 30 of the basket 24 into the loading space of the shopping cart 15.
- the driving pin 82 engages with the driving pin 82 and thereby pivots the panel 32 into its passive position. This passive position is shown in dashed lines and marked with "A".
- the camera module 62 thus always sees only the board 32 of the last shopping trolley 15 in a row, namely until a new shopping trolley 11 is added or the last shopping trolley set is removed again.
- This embodiment has the advantage that the panels 32 are at rest during the detection and can therefore be detected more easily.
- the time during which the marking 36 can be detected is longer than in the first embodiment, since the board 32 remains in the detection range of the camera module 62 until the next shopping cart is inserted.
- the result of this is that the detection processes have to take place less frequently, as a result of which energy can be saved. This is particularly important if the collection point is powered by batteries or solar cells.
- FIGS. 8 and 9 A third embodiment is shown in FIGS. 8 and 9.
- the panel 32 is attached in such a way that the panel 32a is not activated in a free-standing shopping cart 11, but is only activated by being pushed into the shopping cart 15 in front of it.
- the board 32 of the shopping cart 15, which was previously the last shopping cart and is now the penultimate shopping cart, is moved from the active to the passive state.
- FIG. 9 shows in detail the area of the panel 32 from FIG. 8.
- the panel 32 is acted upon by a torsion spring 84 in a first position “A”.
- the panel 32 In the position “A”, the panel 32 is in the passive state.
- the free end of the board 32 hits the floor of the shopping cart in front of it and the board is pivoted about its pivot axis into a vertical position “B”.
- the board 32 In the position “B”, the board 32 is in the active position Status.
- the driver lever 82 protrudes into the basket. The marking on the board can be recognized by the camera 62. If a further shopping cart is now inserted, it pushes against the driver lever 82 and pivots the board 32 into the position "C”. In position "C”, panel 32 is again in a passive state.
- FIG. 10 shows a fourth embodiment, in which the panels 32 are attached under the loading surface of the shopping trolleys 11, 15, 16 approximately at the level of the rollers.
- the camera 62 is located just above the floor between the rollers.
- the shopping cart can hereby be freely pushed forward over the camera 62.
- FIGS. 6 and 7 The embodiment described under FIGS. 6 and 7 is very suitable for removing the shopping trolleys from the beginning of the row, in which the panel 32 of the shopping trolley is deactivated as long as a further shopping trolley is inserted.
- the system can determine how many shopping trolleys have been removed from the front and thus calculate the number of shopping trolleys at the front of the stack. In this embodiment, it can now be provided that the customer receives a bonus or even an additional bonus if he pushes the entire stack forward when inserting the shopping cart he brought back. As a result, the "wandering" of the stack to the rear can be compensated for.
- the panels 32 can be designed such that the panels 32 of the shopping cart fold in as soon as goods are placed in the shopping cart. If the shopping cart with goods in the basket is returned and pushed into the last shopping cart, this does in fact “deactivate” the marking on the last shopping cart, but since the board 32 of the inserted shopping cart is blocked in the passive position, no return is recognized and no bonus is given.
- Another manipulation option for the customer is that he removes the shopping cart and shortly afterwards pushes it back into the collection point and then receives a bonus without having used the shopping cart for a purchase.
- a bonus is only issued after a certain period of time. It is also conceivable to make the value of the bonus dependent on the duration of this period and so on Reward customers who have been in the shopping market longer with a higher bonus.
- the markings and boards attached to the shopping cart can be manufactured inexpensively and replaced with little effort. They are also not dependent on their own energy supply. The presence of a marking on the shopping cart and the mechanical function of the boards can be checked in a simple manner, as a result of which the maintenance costs are low.
- optical markings of the shopping trolleys are also conceivable, which do not require any mechanical means for changing the state from the active to the passive state and vice versa:
- a marking that can be read from above or below can be attached to the bottom of the shopping cart the next shopping cart or the shopping cart in front of it is covered in a stack row exactly when it is transferred to a passive state when the two shopping carts concerned are properly pushed into one another. Any mechanical parts for switching the marking are then not necessary.
- a passive electronic marking is, for example, a so-called
- Transponder When using transponders, for example, be used that transponders emit “response signals" of different strengths depending on the position.
- the shielding properties of the metal basket on the shopping cart and, for example, to arrange the transponder either inside the basket or outside the basket, depending on the condition.
- LCD displays can be used as another conceivable marking with electronic components.
- the identification features belonging to a shopping cart can be shown on the LCD display.
- the LCD display can change its display status depending on whether the shopping cart is free, whether the shopping cart is inserted into a previous shopping cart or whether a subsequent shopping cart is inserted.
- the display can for example consist of a transparent LCD display, which is attached under the bottom of the basket.
- the inactive state of the identification marks can be established by switching the displays transparently. In the active state, on the other hand, they are opaque and display the identification feature of the respective shopping cart.
- the system can also be used for any other type of transport trolley which is temporarily made available.
