As a better embodiment, the bottom of the storage box is provided with a shockproof pad to prevent the goods from being broken.
The specific implementation mode of the invention is as follows:
the specific shopping process is shown in fig. 9, when a user enters a supermarket and uses the supermarket self-service shopping cart to shop, the user firstly indicates that shopping bags are needed or the shopping bags are not needed on the display screen 8; after a commodity is selected, the commodity is put in from the commodity entrance 6, in the putting process, when the infrared heat release sensor 10 senses that a hand of a user reaches the position above the commodity entrance 6, the control panel 27 controls the linear motion driving mechanism 24 of the sliding door 13 arranged at the commodity entrance 6 to automatically open the sliding door 13, the user can put the commodity in from the commodity entrance 6, when the commodity is put, the bar code is directed to one end of the circuit mounting box 7 as far as possible, when the infrared heat release sensor 10 senses that the hand leaves, the sliding door 13 is closed, the commodity is put in from the commodity entrance 6 and stays on the counter door arranged in the shopping cart body 1, at the moment, if a shopping bag is required for initial selection, the code scanning is successful, the control panel 27 records commodity information, the display screen 8 displays the commodity information, the control panel 27 controls the counter door 15 to rotate clockwise by 90 degrees around the rotating shaft by controlling the first speed reduction stepping motor one 25, the second door 16 is controlled to rotate 30 degrees counterclockwise around the rotating shaft by the second speed-reducing stepping motor 26 (the rotating angle can be set according to requirements, and the optimal angle can also be found out through experiments), and after the first door 15 and the second door 16 are opened, commodities can fall into the shopping bag in the first storage box 18 due to the limitation of the angle; similarly, if the shopping bag is not needed in the initial selection, after the code scanning is successful, the control board controls the second door 16 to rotate 90 degrees clockwise around the rotating shaft by controlling the second deceleration stepping motor 26, controls the first door 15 to rotate 30 degrees anticlockwise around the rotating shaft by controlling the first deceleration stepping motor 25, and after the first door 15 and the second door 16 are opened, the commodity falls into the second storage box 19 due to the limitation of the angle, as shown in fig. 5; after determining that the commodity falls down, the control board 27 controls the first speed reduction stepping motor 25 and the second speed reduction stepping motor 26 to close the opposite doors; if the small goods are still to be purchased, the next cycle is entered.
If shopping bags are preset in the two storage boxes, the shopping commodities are classified and placed in the two storage boxes through the opposite doors and are separately packaged, and the commodities which are not suitable for being placed in a mixed mode, such as food and cleaning lotion, are prevented from being mixed together.
The operation of sweeping the sign indicating number of major possession commodity only need manually take bar code scanning rifle 9 sweep alone can, sweep and can pass through control panel 27 record and categorised after the sign indicating number is successful, it is major possession commodity class to look over on the display screen 8, if the staff observes that there is customer's major possession commodity to place when having commodity in the basket, will verify commodity and the list of major possession commodity class on the display screen 8 to prevent that some unconscious customer from putting into major possession commodity with the smallclothes commodity and placing in the basket and not sweep the sign indicating number and settle accounts.
Every purchase a commodity, control panel 27 just inputs commodity information, carries out communication information exchange through wireless communication device and supermarket settlement system to on calculating current total sum and showing display screen 8, when shopping finishes, click the settlement on the screen, then can generate the payment two-dimensional code and sweep the sign indicating number settlement, after the payment is successful, control panel 27 control electromagnetic lock 23 unblock on the corresponding storing steamer tray, then the user pulls open the storing steamer tray and can take away commodity. When the storage drawer is selected before shopping, the commodity information column on the display screen can automatically add the information and price of the shopping bag, and the settlement is carried out together, after the payment is successful, the electromagnetic lock on the storage drawer I is opened, and a user can directly lift the shopping bag after pulling the storage drawer I, so that the user does not need to take the commodity outwards one by one; however, many environment-friendly people do not want to use plastic shopping bags, and choose to use the shopping bags on the display screen, after payment is completed, the electromagnetic lock of the second storage drawer is opened, and the user pulls the second storage drawer out, so that the drawer can be pulled out and the goods can be taken out and put into the bag, which is more convenient than taking the goods out by opening the cabinet door; after the commodity is taken away, the storage drawer is closed, and the information on the display screen is cleared.
The embodiment of the invention also has the following technical characteristics:
the control panel can adopt a PLC controller, the power supply can adopt a 12V direct current switching power supply, the display screen is an industrial control color screen, and the bar code scanning gun, the infrared pyroelectric sensor, the omnidirectional code scanning platform, the electromagnetic lock and the like are mature products and can be directly purchased; the linear motion driving mechanism 24 for controlling the sliding door can adopt a synchronous belt transmission mechanism, and the speed reduction stepping motor for controlling the opening and closing of the sliding door can adopt a 42-planetary speed reducer.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
