Description

Technical Field

[0001] The present invention relates to the technical field of logistics sorting, and in particular to a logistics sorting device based on the Internet of Things. Background Art

[0002] Traditional logistics sorting methods rely on a lot of manpower, which is not only inefficient, prone to errors, but also costly. Logistics sorting equipment based on the Internet of Things has emerged. By integrating advanced Internet of Things technology, it has realized intelligent and automated sorting of goods, greatly optimizing the logistics process. With the rapid development of e-commerce, the number of goods has exploded, and intelligent sorting has become a key link in improving express processing efficiency, reducing labor costs, and reducing error rates.

[0003] In the Chinese invention patent application with publication number CN117563969A, an automatic identification and sorting device for defective products for a logistics supply chain is proposed. Two support rods are arranged between two fixed seats, which can make the fixed seats rotate. At this time, one support rod will translate along the top of the limit frame, so as to gradually convey the goods forward. At this time, the camera on the mounting rod will move downward to increase the distance from the goods, so that the camera can shoot and identify the bottom of the goods. The distance between the two support rods is large, which is convenient for the camera to shoot and identify the bottom of the goods, which is conducive to improving the identification effect of defective goods.

[0004] However, since the goods on the logistics sorting line are continuous and adjacent goods are connected head to tail during the transmission process, multiple goods will move to the recognition position of the recognition camera at the same time. Similar information on multiple express deliveries (such as similar barcode formats, labels with similar colors, etc.) will confuse the recognition algorithm. The barcodes of adjacent goods partially overlap in the image. The recognition software may mistakenly interpret them as one barcode or interpret wrong information, thereby affecting the accuracy of sorting. Summary of the invention

[0010] Optionally, the pressure-applying part includes a convex strip, a threaded sleeve, a groove and a threaded groove. Two symmetrically arranged convex strips are fixedly installed on the shaft of the extension shaft. The convex strips are connected to the threaded sleeve for sliding up and down. A groove for sliding is provided on the inner arc surface of the threaded sleeve. A threaded groove is provided inside the support tube. The support tube is threadedly connected to the threaded sleeve via the threaded groove. A first friction ring is fixedly installed on the top of the threaded sleeve.

[0011] Optionally, the first friction ring and the second friction ring both have an annular structure, the extension shaft passes through the centers of the first friction ring and the second friction ring, and a rubber buffer block is fixedly installed between the threaded sleeve and the first friction ring.

[0012] Optionally, the top of the sorting line is provided with an identification component, which includes a gantry, a rotating frame, an extension shaft, a lifting piece, a support frame and an identification camera.

[0016] Compared with the prior art, the present invention has at least one of the following beneficial technical effects: In the present invention, the elastic force of the second torque spring is smaller than that of the first torque spring, and the roller rolls on the surface of the goods, so the friction force of the front blocking plate on the goods is greater than the friction force of the rear blocking plate on the goods. Therefore, the goods that have entered the identification position are guided and centered to enter the identification area, while the goods to be identified and sorted are slowed down, so that two adjacent goods are separated, avoiding the partial overlap of the bar codes of adjacent goods to affect the accuracy of identification and sorting.

[0017] Furthermore, the larger the volume of the cargo, the greater the resistance required to hinder its movement. Therefore, the front separation shaft rotates and drives the extension shaft to rotate, so that the threaded sleeve rotates and moves upward, and the threaded sleeve pushes the first friction ring upward to make it contact with the second friction ring, thereby increasing the friction force. The larger the cargo, the greater the rotation angle of the front separation shaft, thereby increasing the rotational resistance of the front separation shaft to achieve a deceleration effect. At the same time, small-volume cargo is subject to less resistance. The resistance is adjusted according to the size of the cargo to avoid the problem that large-volume cargo cannot hinder its movement and small-volume cargo cannot move.

[0018] Furthermore, the movement of the goods drives the turntable to rotate, so that the height of the identification camera rises. When the goods come into contact with the turntable to cause it to rotate, the turntable causes the height of the identification camera to change, thereby adjusting the height of the identification camera according to the height of the goods, so that the distance between the identification camera and the goods is within the range of the optimal scanning distance of the identification camera, thereby improving the accuracy of identification and sorting.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Example 1 This embodiment proposes a logistics sorting device based on the Internet of Things, such as Figure 1 As shown, it includes a sorting line 1, a plurality of driving rollers 2 are rotatably connected in the middle of the sorting line 1, a conveyor belt 3 is conveyed at the arc surface of the plurality of driving rollers 2, a baffle plate 4 for blocking goods is fixedly installed on the top of the sorting line 1, the driving rollers 2 provide drive for the conveyor belt 3 to transport goods, the baffle plate 4 prevents goods from falling from the baffle plate 4, and an identification component 7 for identifying goods is arranged on the top of the sorting line 1.

[0027] like Figure 2 and Figure 3 As shown, a separation component 5 is arranged at the top of the sorting line 1, and the separation component 5 includes a front separation shaft 51, a rear separation shaft 54, a shielding member, a first torque spring 56, a support cylinder 57 and a second torque spring 58. The top of the sorting line 1 is rotatably connected to the front separation shaft 51 and the rear separation shaft 54. The front separation shaft 51 is closer to the head end of the sorting line 1 than the rear separation shaft 54. The side of the baffle plate 4 is fixedly installed with a support cylinder 57, and the interior of the support cylinder 57 is rotatably connected to the front separation shaft 51 and the rear separation shaft 54.

[0028] Two front separation shafts 51 and two rear separation shafts 54 are provided, and the two front separation shafts 51 are respectively located on the left and right sides of the conveyor belt 3, and the two rear separation shafts 54 are respectively located on the left and right sides of the conveyor belt 3, and the front separation shafts 51 and the rear separation shafts 54 are distributed in a straight line along the sorting line 1. The shielding member includes a front blocking plate 52, a roller 53 and a rear blocking plate 55, and the front blocking plate 52 is fixedly installed on the side of the front separation shaft 51, and the rear blocking plate 55 is fixedly installed on the side of the rear separation shaft 54, and the end of the rear blocking plate 55 away from the rear separation shaft 54 ​​is rotatably connected to the roller 53, and the roller 53 rolls on the surface of the goods.

[0029] The front separation shaft 51 and the front blocking plate 52 cooperate to slow down the goods to be identified, and the rear separation shaft 54, the roller 53 and the rear blocking plate 55 cooperate to guide the goods. The elastic force of the second torque spring 58 is used to make both sides of the goods receive the same thrust, so that the goods are centered and the barcode on it can be photographed and identified by the identification component 7.

[0030] The bottom of the support cylinder 57 is elastically connected to the front separation shaft 51 through the first torque spring 56, and is elastically connected to the rear separation shaft 54 ​​through the second torque spring 58. The elastic force of the second torque spring 58 is smaller than the elastic force of the first torque spring 56, so the friction force of the front blocking plate 52 on the cargo is greater than the friction force of the rear blocking plate 55 on the cargo.

[0031] In this embodiment, the elastic force of the second torque spring 58 is smaller than the elastic force of the first torque spring 56, and the roller 53 rolls on the surface of the goods. Therefore, the friction force of the front blocking plate 52 on the goods is greater than the friction force of the rear blocking plate 55 on the goods. Therefore, the goods that have entered the identification position are guided and centered to enter the identification area, while the goods to be identified and sorted are slowed down, so that two adjacent goods are separated, avoiding the partial overlap of the barcodes of adjacent goods to affect the accuracy of identification and sorting.

[0032] Example 2 Based on Example 1, this example proposes a logistics sorting device based on the Internet of Things, such as Figure 3 and Figure 4 As shown, the resistance adjusting member 6 includes an extension shaft 61, a pressure member, a first friction ring 67 and a second friction ring 68. The bottom end of the extension shaft 61 is fixedly connected to the front separation shaft 51, and the top end of the extension shaft 61 is rotatably connected to the support tube 57. A pressure member that slides up and down is provided at the shaft of the extension shaft 61. The first friction ring 67 is fixedly installed on the top of the pressure member, and the second friction ring 68 is fixedly installed on the top inner wall of the support tube 57. The first friction ring 67 is in contact with the second friction ring 68.

[0033] By rotating the front separation shaft 51 and the extension shaft 61, the pressure member applies pressure to the first friction ring 67 to increase the friction between it and the second friction ring 68, thereby increasing the friction encountered by the extension shaft 61 during rotation. The greater the rotation angle of the front separation shaft 51, the greater the resistance encountered by the front separation shaft 51 during rotation, thereby automatically identifying the volume of the cargo. The larger the volume of the cargo, the greater the resistance that hinders its movement needs to be, otherwise it cannot be slowed down. When obstructing small-volume cargo, since small-volume cargo can only cause the front separation shaft 51 to rotate a small angle, the resistance encountered by small-volume cargo is small, so that it can pass over the front obstruction plate 52.

[0034] The pressure member includes a convex strip 62, a threaded sleeve 63, a groove 64 and a threaded groove 65. Two symmetrically arranged convex strips 62 are fixedly installed at the shaft of the extended shaft 61. The convex strip 62 is connected to the threaded sleeve 63 for sliding up and down. The inner arc surface of the threaded sleeve 63 is provided with a groove 64 for sliding. The inner part of the support tube 57 is provided with a threaded groove 65. The support tube 57 is threadedly connected to the threaded sleeve 63 through the threaded groove 65. The top of the threaded sleeve 63 is fixedly installed with a first friction ring 67. The first friction ring 67 and the second friction ring 68 are both annular structures, and the extended shaft 61 passes through the center of the first friction ring 67 and the second friction ring 68.

[0035] The front separation shaft 51 rotates and drives the extension shaft 61 to rotate. The extension shaft 61 uses the convex strip 62 to make the threaded sleeve 63 rotate synchronously. Since the threaded sleeve 63 is threadedly connected with the first friction ring 67, the threaded sleeve 63 rotates and moves upward. The threaded sleeve 63 pushes the first friction ring 67 upward to make it contact with the second friction ring 68, thereby increasing the friction force. Therefore, the greater the rotation angle of the front separation shaft 51, the greater the friction force between the first friction ring 67 and the second friction ring 68.

[0036] A rubber buffer block 66 is fixedly installed between the threaded sleeve 63 and the first friction ring 67. The rubber buffer block 66 acts as an elastic avoidance to prevent the first friction ring 67 and the second friction ring 68 from getting stuck instantly after contact, causing the extension shaft 61 to be unable to rotate.

[0037] In this embodiment, the larger the volume of the cargo, the greater the resistance required to hinder its movement. Therefore, the front separation shaft 51 rotates and drives the extension shaft 61 to rotate, so that the threaded sleeve 63 rotates and moves upward, and the threaded sleeve 63 pushes the first friction ring 67 upward to make it contact with the second friction ring 68, thereby increasing the friction force. The larger the cargo, the greater the rotation angle of the front separation shaft 51, thereby increasing the rotational resistance of the front separation shaft 51 to achieve a deceleration effect. At the same time, small-volume cargo can only cause the front separation shaft 51 to rotate a small angle, and the small-volume cargo is subject to less resistance. The resistance is adjusted according to the size of the cargo to avoid the problem that large-volume cargo cannot hinder its movement and small-volume cargo cannot move.

[0038] Example 3 Based on the above-mentioned embodiment 1 or embodiment 2, this embodiment proposes a logistics sorting device based on the Internet of Things, such as Figure 5-Figure 7 As shown, the identification component 7 includes a gantry 71, a rotating frame 72, an extension shaft 73, a lifting member, a support frame 77 and an identification camera 79. The gantry 71 is fixedly installed on the top of the sorting line 1. The interior of the gantry 71 is rotatably connected to the rotating frame 72 through a rotating shaft. The extension shaft 73 is fixedly installed at the end of the rotating shaft of the rotating frame 72. The goods move from the bottom of the rotating frame 72, and the rotating frame 72 is driven to rotate by the goods. The larger the rotation angle of the rotating frame 72, the higher the goods.

[0039] A lifting piece is provided at the end of the extension shaft 73, and a support frame 77 is fixedly installed at the top of the sorting line 1 and behind the gantry 71. The bottom of the support frame 77 slides up and down to connect the identification camera 79, the extension shaft 73 is connected to the identification camera 79 through the lifting piece, the rotating frame 72 adopts an inverted U-shaped structure, the identification camera 79 is misaligned with the rotating frame 72, and the side of the rotating frame 72 contacts the goods. The lifting piece includes a rotating plate 74, a lifting plate 75, an adjustment bent rod 76 and a connecting rod 78. The side of the support frame 77 is slidably connected to the adjustment bent rod 76, and the two ends of the adjustment bent rod 76 are respectively fixedly installed with the identification camera 79 and the connecting rod 78. The bottom end of the connecting rod 78 is fixedly installed with the lifting plate 75, and the end of the extension shaft 73 is fixedly installed with the rotating plate 74, and the top of the rotating plate 74 contacts with the lifting plate 75.

[0040] The rotating frame 72 drives the extending shaft 73 and the rotating plate 74 to rotate, and the rotating plate 74 lifts the lifting plate 75 and the adjusting bent rod 76, so that the height of the identification camera 79 rises. Since the optimal scanning distance of the identification camera 79 is fixed, when scanning low-height goods, the height of the identification camera 79 is in an initial state.

[0041] A buffering hydraulic rod 710 is fixedly installed at the bottom of the support frame 77, and an identification camera 79 is fixedly installed at the bottom of the buffering hydraulic rod 710. The goods are transported directly below the identification camera 79. When the identification camera 79 and the lifting plate 75 are no longer pushed upward by the rotating plate 74, the identification camera 79 moves downward. Due to the existence of the buffering hydraulic rod 710, the identification camera 79 moves downward slowly, avoiding the identification camera 79 from moving downward too fast to generate vibration and cause damage to the identification camera 79.

[0042] In this embodiment, the movement of the goods drives the turntable 72 to rotate, so that the height of the identification camera 79 rises. When the goods come into contact with the turntable 72 to cause it to rotate, the turntable 72 causes the height of the identification camera 79 to change, thereby adjusting the height of the identification camera 79 according to the height of the goods, so that the distance between the identification camera 79 and the goods is within the range of the optimal scanning distance of the identification camera 79, thereby improving the accuracy of identification and sorting.

[0043] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
