Description

Technical Field

[0001] This invention relates to the field of transportation equipment, and more specifically to an integrated material pallet scanning and conveying device. Background Technology

[0002] Warehousing is a crucial link between production and consumption. Common forms of warehousing include: Figure 1 , Figure 2 As shown, after placing at least one material 102 on the material tray 101 for placing materials to form a basic material unit 1, the basic material unit 1 is placed on the shelf.

[0003] With the advancement of network technology, warehouse management has become more intelligent. People have begun to set labels 103 on material pallets 101 and various materials. The labels 103 have barcodes, QR codes, or RFID tags. In this way, when basic material unit 1 enters or leaves the warehouse, the labels 103 on material pallets 101 and materials 102 can be scanned, so that the information of materials 102 on material pallets 101 is bound to the information of material pallets 101, making the management of each basic material unit 1 more intelligent, accurate, and detailed.

[0004] However, current integrated barcode scanning and conveying equipment usually only installs the barcode scanning device at a fixed angle. This requires confirming the orientation of the material 102 when placing it, and ensuring that the side of the material 102 and the material tray 101 with the label 103 face a specific position. This greatly increases the workload. In addition, the material is transported by a traditional conveyor belt, and the basic material unit is prone to displacement during the transport process, which increases the difficulty of barcode scanning.

[0005] Therefore, existing integrated material pallet scanning and conveying equipment is not convenient to use. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a material pallet scanning and conveying integrated device that is relatively easy to use.

[0007] To solve the above-mentioned technical problems, the present invention provides an integrated material pallet scanning and conveying device, which includes a conveying unit for conveying basic material units from front to back and a scanning unit for scanning the labels of the basic material units on the conveying unit.

[0008] The conveying unit includes a fixing component that can move back and forth to fix the basic material unit;

[0009] The scanning unit includes a liftable square frame, on which a scanning component is installed to scan the front, back, left and right sides of the basic material unit.

[0010] As a further improvement of the present invention, the conveying unit includes a first drive member for moving the fixed component back and forth.

[0011] Preferably, the first driving component includes two parallel first lead screws that can rotate synchronously in the same direction and a first mounting bracket for rotatably mounting the two first lead screws. The central axes of the two first lead screws are perpendicular to the left and right directions. Each first lead screw is provided with a first lead screw nut that matches the first lead screw, and both first lead screw nuts are fixedly connected to the fixing component.

[0012] As a further improvement of the present invention: the fixing component includes a second mounting bracket, on which a first blocking member and a second blocking member of the same shape, structure and size are mounted from front to back.

[0013] As a further improvement of the present invention: the scanning unit includes a second drive member for driving the square frame to rise and fall.

[0014] Preferably, the second driving component includes four parallel second lead screws that can rotate synchronously in the same direction and a second motor for driving the four second lead screws to rotate; the second motor and the four second lead screws are connected by a transmission component; each second lead screw is provided with a second lead screw nut that matches the second lead screw, and each second lead screw nut is fixedly connected to the square frame.

[0015] As a further improvement of the present invention: the square frame is composed of four side frames, and a scanning device capable of reciprocating along the length of the side frame is slidably mounted on each side frame. A third driving component for driving each scanning device to move synchronously is mounted on the square frame.

[0016] Preferably, the third driving component includes friction wheels rotatably mounted at the four corners of the top of the square frame, each capable of rotating in a vertical direction. The central axis of the friction wheels is perpendicular to the horizontal direction. A steel wire rope is wound around each friction wheel. A third motor for driving one of the friction wheels is mounted on the square frame. A slider capable of reciprocating along the length of each frame is slidably mounted on each side frame. Each slider is detachably and fixedly connected to the steel wire rope. Each barcode scanner is fixedly mounted on its respective slider. The labels scattered throughout the basic material unit are scanned by the barcode scanner, which can move along the side frame.

[0017] Preferably, a camera for capturing panoramic images of the front, back, left, or right side of the basic material unit is fixedly installed at the top of each frame. This allows the status of the basic material unit to be recorded while recording information, facilitating management.

[0018] The beneficial effects of this invention are as follows: The integrated material pallet scanning and conveying device provided by this invention is relatively simple to use. Fixing the basic material units with fixing components reduces displacement of the basic material units, making the scanning process simpler. Furthermore, with a scanning component capable of scanning the front, back, left, and right sides of the basic material units, materials can be placed directly on the material pallet regardless of the label's location, greatly reducing workload and making the device even more convenient to use.

[0045] like Figure 3 , Figure 4 , Figure 5 , Figure 11 , Figure 12As shown, the square frame 3 is equipped with a barcode scanning component 4 capable of scanning the front, back, left, and right sides of the basic material unit 1. The barcode scanning component 4 includes four scanning devices 401. The square frame 3 consists of four side frames 301, and each side frame 301 has a scanning device 401 slidably mounted on it, capable of reciprocating along the length of the side frame 301. A camera 9 for capturing panoramic images of the front, back, left, or right sides of the basic material unit 1 is fixedly mounted on the top of each side frame 301. A third drive component 7 is mounted on the square frame 3 to drive the scanning devices 401 to move synchronously. The third driving component 7 includes friction wheels 701 that are rotatably mounted at the four corners of the top of the square frame 3 and can rotate in the vertical direction. The central axis of the friction wheels 701 is perpendicular to the horizontal direction. A steel wire rope 702 is wound around each friction wheel 701. A vertical third motor 703 is mounted on the square frame 3 to drive one of the friction wheels 701 to rotate. The output shaft of the third motor 703 is fixedly connected to the friction wheel 701. A slider 704 that can slide back and forth along the length of the frame 301 is slidably mounted on each frame 301. Each slider 704 is detachably fixedly connected to the steel wire rope 702. Each barcode scanner 401 is fixedly mounted on each slider 704. Each slider 704 has a clamping component fixedly installed on its top for clamping the wire rope 702. The clamping component includes an upper pressure block and a lower pressure block. The contact surface of the upper pressure block and the lower pressure block is provided with a groove for accommodating the wire rope 702. The upper pressure block and the lower pressure block are detachably fixedly connected by four screws. The clamping degree of the clamping component on the wire rope 702 can be adjusted by rotating the screws.

[0046] The working principle of this invention is as follows: Workers use a trolley or forklift to transport the basic material unit 1 to the loading area of ​​the conveying unit. After placing the basic material unit 1 on the roller 5021 and pushing it backward, the left wedge 202L and right wedge 202R of the first blocking member contact the basic material unit 1 and move backward under the force of the basic material unit 1. The left return spring 203L and right return spring 203R of the first blocking member are compressed, continuing to push the basic material unit 1 backward until the rear side of the basic material unit 1 contacts the second blocking member. When the left wedge 202L and right wedge 202R of the first blocking member are removed, the basic material unit 1 is no longer in contact with the left wedge 202L and right wedge 202R of the first blocking member. After losing the force applied by the basic material unit 1, the left return spring 203L and right return spring 203R of the first blocking member gradually extend back to their natural extension state, causing the left wedge 202L and right wedge 202R of the first blocking member to move towards each other. In this way, the basic material unit 1 is fixed in the left frame 201L, right frame 201R, first blocking member and second blocking member.

[0047] The first motor 504 is started, and the output shaft of the first motor 504 rotates, driving the first gear 505 to rotate. The rotation of the first gear 505 drives the second gear 506 to rotate, and the second gear 506 drives the first rotating shaft 503 to rotate. The first rotating shaft 503 drives the first bevel gear to rotate through the second bevel gear and drives the third bevel gear to rotate through the fourth bevel gear, thereby driving the two first lead screws 501 to rotate synchronously and in the same direction. This causes the two first lead screw nuts to move from front to back, thereby driving the fixed assembly 2 to move backward. The backward movement of the first lead screw nuts drives the left frame 201L and the right frame 201R to move backward. Through the left wedge block 202L and the right wedge block 202R of the first blocking member, the basic material unit 1 is driven to slide backward on the roller 5021.

[0048] When basic material unit 1 arrives at the scanning area, the second motor 602 is started. The output shaft of the second motor 602 drives the third gear 606 to rotate. The third gear 606 drives the fifth lead screw 605 to rotate through the fourth gear 607. The fifth lead screw 605 drives the third lead screw 603 to rotate through the fifth bevel gear 608 and the sixth bevel gear, and drives the fourth lead screw 604 to rotate through the eleventh bevel gear 609 and the twelfth bevel gear. The third lead screw 603 drives the second lead screw 601 located in front on the left side to rotate through the seventh bevel gear and the eighth bevel gear, and drives the second lead screw 601 located in rear on the left side to rotate through the ninth bevel gear and the tenth bevel gear. The fourth lead screw 604 drives the second lead screw 601 located in front on the right side to rotate through the thirteenth bevel gear and the fourteenth bevel gear, and drives the second lead screw 601 located in rear on the right side to rotate through the fifteenth bevel gear and the sixteenth bevel gear, thereby driving the four second lead screw nuts to descend, causing the square frame 3 to descend.

[0049] After each camera 9 captures a panoramic image of the front, back, left, and right sides of the basic material unit 1, the square frame 3 continues to descend and stops at each material. The third motor 703 is then activated, which drives the friction wheel 701, which is fixedly connected to its output shaft, to rotate. The rotation of the friction wheel 701 drives the steel wire rope 702 to rotate, which in turn drives the other friction wheels 701 to rotate. The rotation of the steel wire rope 702 causes each slider 704 to slide synchronously along the length of the frame 301. The barcode scanning device 401 moves along with the slider 704 until the slider 704 reaches the end of its travel.

[0050] After the barcode scanner 401 finishes scanning the label 103 on the material 102 of that layer, the square frame 3 continues to descend and remains stationary. When scanning the next layer of material 102, the third motor 703 is controlled to reverse, causing each friction wheel 701 to rotate in the opposite direction, allowing the barcode scanner 401 to return from the end of its stroke to the beginning of its stroke. This process is repeated until all labels 103 on the material tray 101 have been scanned. This achieves omnidirectional scanning of all areas of each layer of material 102, eliminating the need to place the labels 103 uniformly on one side. The second motor 602 reverses, causing each second lead screw 601 to reverse, raising the second lead screw nut and driving the square frame 3 back to its initial position.

[0051] The first motor 504 is started, allowing the basic material unit 1 to continue to be conveyed backward. When the basic material unit 1 reaches the unloading area, it is pulled backward. After being pushed by the basic material unit 1, the left wedge 202L and right wedge 202R of the second blocking member will move in opposite directions under the force of the basic material unit 1. The left return spring 203L and right return spring 203R of the second blocking member are compressed. When the basic material unit 1 is removed, it loses the obstruction of the basic material unit 1. The left return spring 203L and right return spring 203R of the second blocking member gradually extend back to their natural extension state, causing the left wedge 202L and right wedge 202R of the second blocking member to move towards each other.

[0052] The first motor 504 is reversed, causing the fixed component 2 to move forward and return to the initial feeding area.

[0053] It should be noted that the present invention is not limited to the specific structure shown in the accompanying drawings in the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art.
