Description

144812 i144812 i

Opfindelsen angår et kasseslusesystem med indkøbsvogne og til afregning af varer, der optages fra f.eks. en kurv på den med en hjulbærende ramme forsynet indkøbsvogn og anbringes på en disk, på hvilken de føres hen forbi et kasseapparat, 5 medens indkøbsvognene køres gennem en passage langs siden af disken, og hvor mindst én sender-modtager sender en aftastningsstråle på tværs af passagen for indkøbsvognene i et niveau, der ligger lidt over oversiden af den hjulbærende ramme og er indrettet til at frembringe et alarmsignal, når 10 den af senderen udsendte stråle afbrydes af en på en vognramme stående genstand, medens et andet sæt stråler hindrer afgivelse af alarmsignalet, når andet end en indkøbsvogn passerer.The invention relates to a cash-lock system with shopping carts and for the settlement of goods taken from, e.g. a basket on the wheeled frame cart and placed on a disk on which they are passed a cash register, while the cartes are driven through a passage along the side of the disk, and at least one transmitter-receiver transmits a scanning beam across the passage of the shopping carts at a level slightly above the top of the wheel-bearing frame and adapted to produce an alarm signal when the beam emitted by the transmitter is interrupted by an object standing on a carriage frame, while another set of jets prevents the alarm signal from being emitted when something other than a shopping cart passes.

I supermarkeder har det vist sig at være et alvorligt problem, 15 at kunder anbringer ret store mængder varer på indkøbsvognenes hjulbærende ramme og fører dem forbi kasseapparatet uden at få dem registreret af kassereren, idet sidstnævnte kun har ringe muligheder for at observere varer, der befinder sig under kurven på vognen.In supermarkets, it has proved to be a serious problem, 15 customers placing fairly large quantities of goods on the wheel load frame of the shopping carts and passing them by the cash register without having them registered by the cashier, with the latter having little opportunity to observe goods found under the curve of the wagon.

20 Ved et kasseslusesystem af den her omhandlede art skulle man være i stand til at afgøre, om en kunde uretmæssigt forsøger at medtage ikke afregnede varer placeret på indkøbsvognens hjulbærende ramme. Aftastningsstrålen er fortrinsvis en lysstråle til påvirkning af en fotocelle, men kan også være 25 f.eks. en radar- eller ultralydstråle, som aktiverer et alarmsignal, når de afbrydes af genstande, der er anbragt på indkøbsvognens bæreramme. Et problem ved denne form for aftastning er, at alarmsignalet ikke må kunne fremkaldes af indkøbsvognenes styrebøjler og stænger, hvormed kurven er af-30 støttet på rammen, eller af personer, som går gennem passagen uden at medtage en indkøbsvogn. Ved sådanne hyppige "falske alarmer" vil kontrol blive uoverkommelig og aftast-ningssystemet miste sin værdi.20 In a cash lock system of the kind at issue here, one should be able to determine whether a customer is improperly attempting to include unaccounted items placed on the cart's wheel bearing frame. The scanning beam is preferably a light beam to actuate a photocell, but may also be e.g. a radar or ultrasonic beam which activates an alarm signal when interrupted by objects placed on the shopping cart carrier frame. A problem with this kind of sensing is that the alarm signal must not be triggered by the guide rods and rods of the shopping carts, with which the basket is supported on the frame, or by persons passing through the passage without including a shopping cart. At such frequent "false alarms" control will become prohibitive and the scanning system will lose its value.

144812 2144812 2

Et forsøg på at løse dette problem er beskrevet i tysk fremlæggelsesskrift nr. 1.803.480. Herfra kendes et kontrolsystem, hvor en tværgående lysstråle udsendes i et niveau umiddelbart under bunden af vognens kurv, og en stråle i 5 et lidt højere niveau udsendes, så den kan ramme et lysuigennemtrængeligt bånd på en indkøbsvogn. Når den sidstnævnte stråle afbrydes, uden at den førstnævnte stråle samtidig afbrydes, d.v.s. når en vogn passerer, vil en aftast-ningsstråle i et nederste niveau fremkalde et alarmsignal, 10 hvis den rammer en genstand på vognens ramme. Der er imidlertid en alvorlig risiko for, at strålen umiddelbart under kurvens bund afbrydes af genstande på en vogn, så alarmen ikke fungerer. Systemet er kompliceret og kræver en meget nøjagtig indstilling af senderne og giver ikke fuld sikkerhed 15 mod svigtende alarmering eller mod "falsk" alarm. Systemet lader sig heller ikke på simpel måde tilpasse til forskellige vogntyper.An attempt to solve this problem is described in German Laid-Open Publication No. 1,803,480. From this is known a control system in which a transverse beam of light is emitted at a level immediately below the bottom of the cart and a beam of a slightly higher level is emitted so that it can strike a light impervious band on a shopping cart. When the latter beam is interrupted without simultaneously interrupting the former beam, i.e. when a carriage passes, a sensing beam at a lower level produces an alarm signal 10 if it strikes an object on the carriage frame. However, there is a serious risk that the beam immediately below the bottom of the curve is interrupted by objects on a wagon, so that the alarm does not work. The system is complicated and requires a very accurate tuning of the transmitters and does not provide complete security 15 against failing alarms or against "false" alarms. The system is also not easily adapted to different types of vehicles.

Kasseslusesystemet ifølge opfindelsen er ejendommeligt ved, at hver indkøbsvogn bærer en refleksbrik, der er indrettet 20 til at tilbagekaste en hjælpestråle fra mindst én sender-modtager-enhed, såsom en fotocelleenhed, der er indrettet til at aktivere sender-modtageren for afstastningsstrålen, når sender-modtager-enheden modtager den reflekterede hjælpestråle.The box locking system of the invention is characterized in that each shopping cart carries a reflex chip adapted to throw an auxiliary beam from at least one transmitter-receiver unit, such as a photocell unit adapted to activate the transmitter-receiver transmitter beam when transmitter the receiver unit receives the reflected auxiliary beam.

25 ved hjælp af refleksbrikken fås fuldstændig sikkerhed for, at.aftastningsstrålen indkobles, når en vogn passerer, og personer, der passerer uden at medbringe en vogn, kan ikke indkoble strålen. Sender-modtager-enheden for hjælpestrålen, der skal reflekteres, kan let indstilles i højden svarende 30 til højden af refleksbrikken på en hvilken som helst type indkøbsvogn.25 by means of the reflector chip, there is complete assurance that the scanning beam is switched on when a carriage passes and persons passing without carrying a carriage cannot switch on the beam. The transmitter-receiver unit for the auxiliary beam to be reflected can easily be set at a height equal to 30 the height of the reflector chip on any type of shopping cart.

Selv om sender-modtageren og den eller de nævnte sender-modtager-enheder tænkes anbragt på hver sin side af passagen, foretrækkes det ifølge opfindelsen, at sender-modtageren og den eller 35 de nævnte sender-modtager-enheder er anbragt på siden af di- 144812 3 sken, og at sender-modtageren for aftastningsstrålen er indrettet til at samvirke med en på den modsatte side af passagen anbragt refleksbrik eller et refleksbånd. Herved forenkles opbygningen af kasseslusesystemet. Hvis aftastnings-5 systemet er en radarstråle eller lignende stråle med begrænset rækkevidde, kan et sådant refleksbånd helt undværes, og desuden opnås yderligere sikkerhed mod falske alarmer forårsaget af personer, der går uden om vognen langs dens bort fra kassereren vendende side.Although the transmitter-receiver and said transmitter-receiver unit (s) are thought to be positioned on either side of the passage, it is preferred according to the invention that the transmitter-receiver and said transmitter-receiver unit (s) are arranged on the side of the passage. And that the transmitter-receiver for the scanning beam is arranged to cooperate with a reflective chip or a reflective tape arranged on the opposite side of the passage. This simplifies the construction of the box lock system. If the sensing system is a radar beam or similar beam of limited range, such a reflex band may be completely avoided, and further security against false alarms caused by persons passing around the carriage along its away side from the cashier is obtained.

10 Ifølge opfindelsen kan sender-modtageren og den eller de nævnte sender-modtager-enheder til betjening af en disk være anbragt i et bord, der danner en selvstændig enhed ved enden af en i længderetningen forskudt nabodisk. Herved lettes montagen og justeringen af organerne.According to the invention, the transmitter-receiver and said transmitter-receiver unit (s) for operating a disk may be arranged in a table which forms an independent unit at the end of a longitudinally displaced adjacent disk. This facilitates assembly and adjustment of the organs.

15 Sender-modtager-enhederne til start og stop af aftastnings- strålen er ifølge opfindelsen hensigtsmæssigt forbundet med en lampe, der viser, når de navnte enheders sender fungerer, således at kassereren blandt andet har kontrol med, at refleksbrikken på en forbipasserende indkøbsvogn virker.According to the invention, the transmitter-receiver units for starting and stopping the scanning beam are suitably connected to a lamp which shows when the transmitters of the named units function, so that the cashier, among other things, checks that the reflective chip on a passing shopping cart works.

20 Opfindelsen forklares nedenfor under henvisning til tegningen, hvor fig. 1 skematisk viser en indkøbsvogn til kasseslusesystemet ifølge opfindelsen, fig. 2 en del af en disk, der indgår i kasseslusesystemet, hvil-25 ken disk udgør den ene side af en passage for indkøbsvogne, og fig. 3 en del af en anden disk til kasseslusesystemet, hvilken disk er anbragt over for disken i fig. 2 og danner den anden side af passagen for indkøbsvognene.The invention is explained below with reference to the drawing, in which fig. 1 schematically shows a shopping cart for the box lock system according to the invention; FIG. 2 is a part of a disc included in the box lock system, the disc of which forms one side of a shopping cart passage; and FIG. 3 shows a portion of a second disk for the box lock system, which disk is placed opposite the disk of FIG. 2 and form the other side of the passage for the shopping carts.

Den i fig. 1 viste indkøbsvogn har på sædvanlig måde en kurv 9/ der er understøttet på en hjulbærende ramme 10 ved hjælp af en understøtning 11 og vognstyrebøjle 12. Kurven 9 rager frit fremad fra understøtningen 11. Hver indkøbsvogn 9 5 bærer som vist en refleksbrik 1, der eksempelvis kan sidde i et niveau umiddelbart under kurven 9. Vognen kan herved reflektere en hjælpestråle, der udsendes fra en sender-modtager-enhed 2 henholdsvis 3, der er anbragt på siden af en disk 13 i kasseslusesystemet. På denne disk lægges de varer, der optages fra 10 kurven 9, og varerne føres så hen forbi et ikke vist kasseapparat. Sender-modtager-enhederne 2 og 3 kan være lysgiver-fotocelleaggregater eller andre former for sender-modtagerapparater, såsom ultralydgeneratorer og -modtagere eller radarapparatur. Når indkøbsvognen er kørt ind i passagen 15 langs disken 13 til den med stiplede linier i fig. 2 viste stilling, vil refleksbrikken 1 reflektere strålerne fra senderen i enheden 2 tilbage til modtageren i denne enhed, som er således indrettet, at den, når den modtager hjælpestrålen, aktiverer en eller flere på disken 13 monterede sender-20 modtagere 4 og 5, der kan udsende en eller flere aftastningsstråler. Sender-modtagerne 4 og 5 er anbragt i højde umiddelbart over den hjulbærende ramme 10 på indkøbsvognen, så at aftastningsstrålen eller -strålerne vil blive afbrudt af den eller de varer, der måtte befinde sig på rammen. Sender-25 modtagerne 4 og 5 kan være således forbundet, at de, når af- tastningsstrålerne fra begge sender-modtagere afbrydes, tænder en signallampe 8 eller aktiverer et tilsvarende alarmsignal, som kan gøre kassereren ved kasseapparatet opmærksom på, at vognen medfører varer, som skal ses nærmere efter. Det vil 30 forstås, at aftastningsstrålerne ved sender-modtagerne 4, 5 kan passere fra en sender på den ene side af passagen over til en modtager på den anden side af passagen, men for at opnå simplest mulig installation er det bedst, at både sender og modtager i sender-modtagerne 4 og 5 er anbragt på 35 samme side i passagen, og at de udsendte aftastningsstråler reflekteres fra en ekstra refleksbrik eller et ekstra refleksbånd 6, der som vist i fig. 3 og som antydet med stiplede linier i fig. 2 er anbragt lige over for sender-modtagerne 4 ogThe FIG. 1, the cart 9 shown in the usual way has a basket 9 / which is supported on a wheel-bearing frame 10 by means of a support 11 and trolley guide 12. The basket 9 projects freely forward from the support 11. Each shopping cart 9 5 carries, as shown, a reflective piece 1 which for example, may sit at a level immediately below the curve 9. The carriage may thereby reflect an auxiliary beam emitted from a transmitter-receiver unit 2 or 3, respectively, arranged on the side of a disk 13 in the box lock system. On this disk are placed the goods recorded from the basket 9, and the goods are then passed past a cash register not shown. The transmitter-receiver units 2 and 3 may be light-emitting photocell assemblies or other forms of transmitter-receiver apparatus such as ultrasonic generators and receivers or radar apparatus. When the shopping cart is driven into the passage 15 along the counter 13 to the dashed line of FIG. 2, the reflector chip 1 will reflect the rays from the transmitter of the unit 2 back to the receiver of this unit, which is arranged so that when it receives the auxiliary beam it activates one or more transmitter-receivers 4 and 5 mounted on the disk 13, that can emit one or more scanning beams. Transmitter receivers 4 and 5 are positioned at a height immediately above the wheel-bearing frame 10 of the shopping cart so that the scanning beam (s) will be interrupted by the item (s) that may be on the frame. The transmitter 25 receivers 4 and 5 may be connected so that when the sensing jets of both transmitter receivers are interrupted, they turn on a signal lamp 8 or activate a corresponding alarm signal which may alert the cashier at the cash register that the carriage is carrying goods, which should be looked at more closely. It will be appreciated that the scanning beams at the transmitter receivers 4, 5 can pass from a transmitter on one side of the passage to a receiver on the other side of the passage, but for the simplest possible installation it is best that both transmitters and receiver in transmitter receivers 4 and 5 are positioned on the same side of the passage, and that the transmitted scanning beams are reflected from an additional reflex chip or an additional reflex band 6 which, as shown in FIG. 3 and as indicated by dotted lines in FIG. 2 is arranged opposite the transmitter receivers 4 and

144812 5 på den disk, der danner den anden begrænsning af passagen for indkøbsvognene. Når det frie rum under indkøbsvognen 9 har passeret forbi sender-modtagerne 4 og 5, er refleksbrikken 1 nået hen i en 5 stilling ud for sender-enheden 3, hvor den hjælpestråle, der udgår fra denne enhedssender, tilbagekastes til samme enheds modtager, der er således indrettet, at den afbryder aftastningsstrålingen ved sender-modtagerne 4 og 5, så af-tastningen ophører. Sender-modtager-enhederne 2 og 3 kan 10 være således forbundne med en lampe 7, at denne slukkes, når refleksbrikken 1 passerer enheden 2 og atter tændes, når den passerer enheden 3, således at kassereren kan kontrollere, at refleksbrikken fungerer efter hensigten. Af ovenstående vil forstås, at sender-modtager-enhederne 2 og 15 3 tjener til principiel start og stop af sender-modtagerne 4, 5's aftastningsstråler ved henholdsvis indkørsel og udkørsel af indkøbsvognen fra kasseslusen. Idet strålerne fra begge sender-modtagere 4 og 5 skal være afbrudt, for at signallampen 8 lyser, undgås falsk alarm, 20 når eventuelle tynde stivere mellem kurven 9 og rammen 10 passerer strålerne, eller når benet på en person, der spadserer ved siden af vognen, passerer gennem strålerne. Ved en helt frit udkraget kurv 9, som vist på tegningen, og med en passage, der er så smal, at vognen kun lige netop kan pas-25 sere, kan man nøjes med en enkelt sender-modtager 4 og 5,idet sen-der-modtager-enheden 3 så er anbragt således, at den afbryder sender-modtageren 4 eller 5's aftastning umiddelbart før understøtningen 11 passerer aftastningsstrålerne. Patentkrav.144812 5 on the disk forming the second restriction of the passage of the shopping carts. When the free space beneath the shopping cart 9 has passed the transmitter receivers 4 and 5, the reflector chip 1 has reached a 5 position next to the transmitter unit 3, where the auxiliary beam emanating from this unit transmitter is reflected to the same unit receiver which is arranged so that it interrupts the sensing radiation at the transmit receivers 4 and 5 so that the sensing ceases. The transmitter-receiver units 2 and 3 may be 10 connected to a lamp 7 so that it extinguishes as the reflector chip 1 passes the unit 2 and again switches on when it passes the unit 3, so that the cashier can check that the reflector chip is functioning as intended. From the above, it will be understood that the transmitter-receiver units 2 and 15 3 serve in principle to start and stop the transmitter rays of the transmit-receivers 4, 5, respectively, when entering and exiting the shopping cart from the box lock. As the rays of both transmitter receivers 4 and 5 must be switched off for the signal lamp 8 to illuminate, false alarm 20 is avoided when any thin strut between the curve 9 and the frame 10 passes the rays, or when the leg of a person walking next to it the carriage, passing through the rays. With a completely freely drawn out basket 9, as shown in the drawing, and with a passage so narrow that the carriage can only just pass 25, a single transmitter-receiver 4 and 5 can be satisfied, the receiver unit 3 is arranged so that it interrupts the transceiver 4 or 5's scanning immediately before the support 11 passes the scanning beams.
