Description

Technical Field

[0001] The utility model relates to the technical field of commodity settlement equipment, in particular to a commodity settlement information transaction platform. Background Art

[0002] In most cases, when checking out at a supermarket, the customer first places the item on one side of the checkout counter. The cashier then picks up the item and brings it close to the scanner or scans it directly with the scanner, and then places the item on the other side.

[0003] When the cashier is picking up and scanning goods, if they encounter goods that are easy to be damaged or the appearance of which is easy to be destroyed, the cashier will inevitably speed up the manual scanning and fail to handle the goods with care when picking them up and putting them down, thus causing unnecessary disputes. Even if the cashier is careful, when the customer buys a lot of goods, various goods are piled together, especially those packed in plastic bags. It is very easy to pull another plastic bag when picking up one plastic bag, thereby damaging the goods in the other plastic bag or its appearance. Sometimes the scanner cannot easily recognize the barcode, and the cashier often needs to bring the scanner close to the product to recognize it. When the product is a product that is easy to be pressed, such as fruit, it is often accidentally pressed out, which will undoubtedly affect the customer's shopping experience. Utility Model Content

When the belt 4 continues to move, the blocking rod 20 is driven to move together, thereby driving the scanner 14 and the slider 13 to move, and the follower rod 24 also moves accordingly; when the telescopic motor 15 pushes the blocking rod 20 toward the belt 4, the follower rod 24 also moves toward the belt 4, thereby driving the contact block to move toward the belt 4; when the follower rod 24 moves with the slider 13, the first contact block 28 moves the second contact block 43, thereby driving the support plate 33 to rotate around the support rod 31, thereby pressing The third spring 36 is compressed until the second knocking block 41 knocks the knocking plate 30 on the same side and makes a sound, the first contact block 28 continues to move forward and separates from the second contact block 43, and the third spring 36 rebounds the support plate 33 to a position where the support plate 33 and the follower rod 24 are perpendicular. At this time, the first knocking block 40 returns to knock the knocking plate 30 on the same side and makes a sound again; the first contact block 28 that continues to move forward successively moves the second contact block 43 in front, which makes a sound successively, thereby reminding the nearby security guards or staff that there is a problem in the settlement area;When the slider 13 moves with the belt 4 to the end of the slide 12 away from the reminder block 21, the pressure sensor at the end of the slide 12 away from the reminder block 21 is subjected to pressure, and the operation panel 1 receives the pressure information, thereby controlling the rotating motor 6 to stop running, and the belt 4 stops running. After the staff arrives, they take down the scanner 14, and manually scan the goods in the scanning area 11 from the exit end of the scanning area 11 in turn, and then place the scanner 14 on the slider 13, and turn on the telescopic motor 15 through the operation panel 1. The telescopic motor 15 retracts, and the blocking rod 20 retracts from the gap between the two adjacent anti-slip strips 9. The first contact block 28 also moves away from the area where the second contact block 43 is located. The spring 26 pulls the slider 13 back to the end of the slide 12 near the reminder block 21, and the pressure sensor at the end of the slide 12 near the reminder block 21 is subjected to pressure. The operation panel 1 receives the pressure value information of the pressure sensor, controls the rotating motor 6 to start, and the belt 4 continues to run and continues to scan the goods normally; when all the goods of a customer are scanned, the operation panel 1 will perform cost statistics and compare the counting information of the two groups of infrared counters with the quantity information of the goods scanned by the scanner 14. If the quantity information is incorrect, the operation panel 1 will control the telescopic motor 15 to run, and in the above manner, the first contact block 28 will move the second contact block 43, thereby making a knocking sound to remind the staff. When conducting commodity transaction settlement, the user places the commodity on the belt 4, and the belt 4 transports the commodity. The design of the belt 4 can ensure that the commodity is placed stably on the belt 4, and as the belt 4 passes smoothly through the scanning area 11, the commodity is prevented from being squeezed or damaged; at the same time, the structure of the surface of the belt 4 and the structure of the scanning area 11 assist each other. When the scanner 14 cannot identify a certain commodity, the baffle 20 of the scanning area 11 will be stuck in the structure of the surface of the belt 4, thereby driving the scanner 14 to move with the commodity, and at the same time triggering the knocking plate 30 in the reminder block 21 to be knocked, so as to remind the staff that there is a fault in the settlement area. When the scanner 14 moves to the other end of the scanning area 11, the belt 4 stops running to facilitate manual scanning by the staff to ensure that the subsequent scanning process returns to normal scanning order; when the scanner 14 is manually reset to the other end of the scanning area 11, the entire scanning system starts to work normally again. During the operation of the commodity settlement information transaction desk, the commodities selected by customers during the entire shopping process are basically handled by the customers only, which can save supermarket manpower. At the same time, the belt 4 is used to transmit and scan the commodities to avoid frequent picking up and putting down of commodities or damage to commodities during local accumulation. ;
