DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The purpose of the present invention is to provide an unattended warehouse storage and retrieval system to solve the problems existing in the above-mentioned prior art. It can fully extend upward to expand the storage space, increase the amount of inventory in the same area, achieve physical isolation between the recipient and the shelf, eliminate the occurrence of wrong collection and human loss of items, and there is no need for the recipient to search for the goods independently, thereby improving the convenience of retrieving goods.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 3As shown, this embodiment provides an unattended warehouse storage and retrieval system, which can be mainly used for express delivery stations to store and retrieve express parcels, vending machines, lightning warehouses, and fully enclosed warehouse automatic retrieval management. The entire device includes a storage box 1, a conveyor belt 10 and at least one lifting mechanism, all of which are arranged inside the storage box 1. The conveyor belt 10 extends horizontally, and the storage box 1 is provided with a pickup port 11 at the conveying end of the conveyor belt 10, and an information identification mechanism is provided at the pickup port 11; the lifting mechanism includes a mounting platform 8 suspended above the conveyor belt 10, and the bottom of the mounting platform 8 is provided with a plurality of first electric clamps 9 arranged in a horizontal direction and used to clamp the goods. The first electric clamps 9 are directly opposite to the conveyor belt 10, and there is a gap between the first electric clamps 9 and the conveyor belt 10 for storing and transporting goods. When in use, each group of first electric clamps 9 is affixed with a barcode or a QR code corresponding to a unique ID address assigned by the control system, which is used to scan and bind the corresponding barcode or QR code when the goods are put into storage. The specific first electric clamps 9 can be arranged in dozens to thousands according to the size of the space, and each first electric clamp 9 is arranged along the extension direction of the conveyor belt 10, and the opening of each first electric clamp 9 is arranged toward the conveyor belt 10 below; a plurality of first driving mechanisms for respectively driving the first electric clamps 9 to open and close are provided on the installation platform 8, and each first driving mechanism is communicatively connected with the information identification mechanism, and the storage box 1 is built with a control system for controlling the coordination of each mechanism, so that the corresponding opening and closing action of the first electric clamp 9 can be realized through the information identification mechanism and the control system in conjunction with the barcode or QR code on the first electric clamp 9.

[0026] Specific operation of goods entering the warehouse: clamp the goods into the corresponding first electric clamp 9, scan the barcode or QR code of the goods to be entered into the control system through the code scanning mechanism, and bind it with the barcode or QR code scanning information on the first electric clamp 9 to complete the product entry record. At the same time as the product enters the warehouse, each product generates a corresponding serial number and is recorded in the control system. The hoisting mechanism full of goods is installed in the storage box 1 and is located above the conveyor belt 10. Operation of goods leaving the warehouse: at the information identification mechanism, scan the barcode or QR code of the goods to be shipped out by mobile phone or barcode scanning gun, or manually enter the pickup code or product code of the product at the information identification mechanism, the corresponding first electric clamp 9 opens, and the goods fall onto the conveyor belt 10. Furthermore, the details of the beginning balance, warehousing, shipping, ending balance and related time of the entire storage box 1 are recorded. For goods with warranty requirements such as those in vending machines and inventories, the product information such as the date of manufacture and warranty period of the goods can also be converted into a QR code and affixed to the goods for scanning and identification, so that consumers can identify important information such as the product name, specification model, date of manufacture, product ingredients, etc. when purchasing online. The conveyor belt 10 transfers the goods to the pickup port 11 to complete the outbound operation. While completing the outbound operation, the control system unbinds the information connection between the goods and the first electric clamp 9.

[0027] In summary, the entire device hangs and clamps the goods on the first electric clamp 9 and is located above the conveyor belt 10. The software system scans the code or inputs the goods code to identify the goods to be found through the information identification mechanism, and then controls the corresponding first electric clamp 9 to open, and the goods fall onto the conveyor belt 10, so that the goods are directly delivered to the pickup port 11 through the conveyor belt 10. It should be further explained that: first, the entire device avoids the current height restrictions of express delivery stations, automatic vending machines, lightning warehouses, and warehouse shelves. It can be set above the storage shelves and make full use of the space above the storage shelves. It is preferred that multiple storage boxes 1 are stacked above the storage shelves, and there is no need to consider the height restrictions of personnel. The same floor area greatly increases the number of express delivery, automatic vending machines, lightning warehouse goods and inventory materials. Second, the external pick-up person is completely isolated from the goods in the storage box 1, and no one picks up the goods, which prevents the inventory goods from being taken by mistake or lost by human beings. Third, the recipient, self-service purchaser and material collector do not need to search for goods on the shelf. The conveyor belt 10 directly transmits the goods to the fixed pickup port 11, reducing the trouble of manually searching for goods. Fourth, it can realize the digitization of express delivery, sales goods, lightning warehouses and storage materials under the current express post, automatic vending, lightning warehouse and warehouse mode. Through the information identification mechanism, the data of goods can be connected with the online automatic vending system, lightning warehouse system, express post and warehousing system. For automatic vending and lightning warehouse systems, key data such as product production time and shelf life can also be submitted to the sales system through the information identification mechanism for consumers to choose.

[0028] As a preferred embodiment of the present invention, the conveyor belt 10 is equipped with a laser beam photoelectric switch and a second driving mechanism for driving the conveyor belt 10 to transmit. The laser beam photoelectric switch is provided with a transmitter 13 and a receiver 14, both of which are electrically connected to the second driving mechanism. The transmitter 13 and the receiver 14 are installed at both ends of the conveying direction of the conveyor belt 10, and are both located above the conveying surface of the conveyor belt 10 in the vertical direction and close to the conveying surface of the conveyor belt 10. Among them, the transmitter 13 and the receiver 14 form a beam, and when the goods to be picked up fall onto the conveyor belt 10, the goods block the beam light between the transmitter 13 and the receiver 14, triggering the entire laser beam photoelectric switch to be powered on, starting the second driving mechanism to operate, and conveying the goods to the end of the conveyor belt 10, and leaving the conveyor belt 10 to enter the picking port 11, and after the goods leave the conveyor belt 10, the laser beam photoelectric switch turns off the second driving mechanism, and the conveyor belt 10 stops moving. As another embodiment, a conveyor belt 10 without a laser photoelectric switch can be used, and the switch of the conveyor belt 10 can be manually activated to transport the goods dropped on the conveyor belt 10 to the pickup port 11. When scanning the code to pick up the goods, the conveyor belt 10 can also be started by the code scanning mechanism to transport the goods dropped on the conveyor belt 10 to the pickup port 11.

[0029] As a preferred embodiment of the present invention, the storage box 1 is provided with a loading port along one side perpendicular to the conveying direction of the conveyor belt 10, and the loading port is equipped with a cover 15 for closing it. Preferably, the cover 15 can be opened manually or opened by installing an electric control such as a hydraulic support rod 3. The top end of the cover 15 is hinged at the top position of the loading port, and the bottom end of the cover 15 can be continuously connected to the bottom position of the loading port, so that the entire lifting mechanism can be replaced by opening the cover 15, thereby realizing the continuous use of the entire storage box 1.

[0030] As a preferred embodiment of the present invention, a support mechanism located above the conveyor belt 10 is provided in the storage box 1, and a hanging mechanism for detachably connecting to the support mechanism is provided on the top of the mounting platform 8. When all the first electric clamps 9 are fully opened to clear the goods, the hanging mechanism is removed from the support mechanism by opening the cover plate 15, and then the entire lifting mechanism is disassembled to be replaced with a lifting mechanism full of goods, or preferably the hanging mechanism adopts an electric structure, and there is no need to open the cover plate 15, so that the hanging mechanism is separated from the support mechanism by electric control, and then the entire lifting mechanism falls on the conveyor belt 10, and with the transmission of the conveyor belt 10, the lifting mechanism is transported to the cargo pickup port 11, and the lifting mechanism is taken out, and after the goods are re-hook by the first electric control clamp, the cover plate 15 is opened, and the lifting mechanism is re-installed on the support mechanism through the hanging mechanism.

[0031] As a preferred embodiment of the present invention, the supporting mechanism includes a connecting rod 2 extending along the conveying direction of the conveyor belt 10, the connecting rod 2 is installed on the inner wall of the cover plate 15, and is buckled with the cover plate 15 at the middle position of the conveyor belt 10 behind the loading port. The connecting rod 2 is equipped with a support rod 3, and the support rod 3 is movably installed on the connecting rod 2 in the vertical direction, and the hanging structure is detachably installed on the support rod 3. Since the connecting rod 2 is fixed on the inner wall of the cover plate 15, after the cover plate 15 is opened outward to 90 degrees, the connecting rod 2 is located on the upper side of the original storage box 1, and then the support rod 3 is controlled to move with each lifting mechanism in the vertical direction to facilitate the disassembly and assembly of the entire lifting mechanism. And because the connecting rod 2 is installed on the inner wall of the cover plate 15, and is buckled with the cover plate 15 at the middle position of the conveyor belt 10 after the loading port, after the lifting mechanism is reinstalled and the cover plate 15 is buckled, the connecting rod 2 is at the middle position of the conveyor belt 10, so that the support rod 3 and the lifting mechanism are located at the middle position of the conveyor belt 10, so as to ensure that the goods fall on the conveyor belt 10 after being separated from the first electric clamp 9, and can be effectively transported to the pickup port 11. The support rod 3 is located directly below the connecting rod 2 and extends in the same direction as the connecting rod 2 to ensure that the length of the connecting rod 2 matches the length of the conveyor belt 10 as much as possible, so that enough lifting mechanisms can be hung to ensure that the entire storage box 1 stores enough goods.

[0032] As a preferred embodiment of the present invention, the connecting rod 2 is rotatably mounted with a first pulley assembly 4 spaced apart along its extension direction, the supporting rod 3 is mounted with a second pulley assembly 5 spaced apart along its extension direction, the side wall of the storage box 1 is rotatably mounted with a reel 12, and a rope 6 for driving the supporting rod 3 to rise and fall is wound between the first pulley assembly 4, the second pulley assembly 5 and the reel 12. After the cover 15 is opened, the reel 12 is driven to rotate by hand or electric control, and then the rope 6 is driven to move, so that the supporting rod 3 is raised and lowered, and the lifting and lowering work of the hoisting mechanism is completed.

[0033] As a preferred embodiment of the present invention, the hanging mechanism is a second electric clamp 7 hung on the support rod 3, and a third driving mechanism for driving the second electric clamp 7 to open and close is provided on the mounting platform 8. In the specific use process, the opening of the second electric clamp 7 faces upward so that it can be hung on the support rod 3, and the opening of each first electric clamp 9 faces downward so as to clamp the goods.

[0034] As a preferred embodiment of the present invention, the first electric clamp 9 and the second electric clamp 7 have the same structure, and both include a mounting base 18 and two clamping jaws 17. One end of the two clamping jaws 17 are rotatably connected to the mounting base 18 and are both sleeved with a gear ring 16. The two gear rings 16 are meshed for transmission. The other ends of the two clamping jaws 17 are used to clamp goods. The first driving mechanism includes a driving motor installed on the mounting base 18. The output shaft of the driving motor is coaxially connected to one end of any clamping jaw 17 having a gear ring 16, so that the rotating end of one clamping jaw 17 is driven by the output shaft of the driving motor, and the rotating end of the other clamping jaw 17 is driven to rotate after the rotation. Since the rotating ends of the two clamping jaws 17 are both sleeved with a gear ring 16, the two clamping jaws 17 can achieve reverse rotation during the rotation process. Then, when the driving motor rotates forward or reversely, the ends of the two clamping jaws 17 without the gear ring 16 are driven to approach each other to clamp goods, or to move away from each other to open and release goods. Preferably, one of the clamping jaws 17 is fixed, and the other clamping jaw 17 can also be equipped with an electromagnetic switch, which is closed when no power is supplied and opened when power is supplied. Preferably, the end of the clamping jaw 17 for clamping the goods is in a tooth-like structure, and the two clamping jaws 17 can clamp the goods more stably through their own tooth-like structures.

[0035] As a preferred embodiment of the present invention, the first drive mechanism also includes a delay switch, a battery assembly and a single-chip microcomputer shared by each first drive mechanism are installed on the mounting platform 8, the positive and negative poles of each drive motor are connected to a first wire, the first wire is connected to the single-chip microcomputer through the delay switch and then to the battery assembly, and the single-chip microcomputer is connected to the information identification mechanism. After the single-chip microcomputer receives the instruction to take the corresponding goods, it controls the corresponding delay switch to delay for 2 seconds to rotate the corresponding drive motor to drive the first electric clamp 9 to open and put down the goods.

[0036] As a preferred embodiment of the present invention, the first driving mechanism also includes a momentary switch, and the positive and negative poles of each driving motor are connected to a second wire in parallel with the first wire. The second wire is connected to the battery assembly through the electric switch to enable manual control of the opening and closing of the first electric clamp 9, so as to clamp the required cargo on the first electric clamp 9.
