[0002] At present, e-commerce is booming. Every day, tens of thousands of parcels need to pass through the logistics sorting lines of express companies. The speed of parcel sorting has become the key to whether the express logistics industry can be carried out efficiently. In order to improve the speed and accuracy of parcel sorting, some automatic sorting equipment has been widely used.

[0003] However, during use, these devices cannot adjust the position of the parcel on the conveyor belt. When scanning the barcode, the position and angle of the barcode on the parcel are uncertain, which undoubtedly increases the error rate of the equipment scanning the barcode, affecting the overall work efficiency. At the same time, the existing automatic weighing and scanning equipment will pause the conveyor belt when there are parcels with abnormal weight and scanning errors, and manual processing is required. The equipment cannot handle it automatically, which seriously affects the weighing and scanning efficiency of the parcel. For this reason, we propose a parcel conveying weighing and sorting mechanism. Utility Model Content

[0035] like Figure 2 , 3 As shown, the feeding assembly 4 comprises a feeding block 41, a rotating shaft 42, a sprocket ring 43, a chain 44 and a toggle plate 45. The feeding block 41 is fixed in the middle of the corresponding inner side surfaces of the two support plates 1, and the feeding block 41 is located below the first belt conveyor 2.

[0038] The working principle of the parcel conveying weighing and sorting mechanism provided by the utility model is as follows:

[0039] When in use, firstly place the parcel to be transported on top of the first belt conveyor 2. After placement, start the first belt conveyor 2 to transport the parcel.

[0040] Before transportation, the two electric telescopic rods 71 ​​can be started. After the two electric telescopic rods 71 ​​are started, the two racks 73 are moved. The movement of the two racks 73 drives the two gears 63 to rotate. The rotation of the two gears 63 drives the two fixed frames 64 to rotate. In this case, when the first belt conveyor 2 transports the package, all the guide wheels 65 inside the two fixed frames 64 guide the package. In this case, it can be stably moved to the bottom of the express scanner 92 for scanning, thereby effectively reducing the error rate of the equipment scanning.

[0041] When the package is transported to the top of the storage plate 52, the weighing sensor 51 can weigh the package. After weighing, the first motor 3 is started to rotate the two shafts 42 to drive the sprocket ring 43 to rotate and then drive the two chains 44 to rotate. The rotation of the two chains 44 drives all the shifting plates 45 to rotate and shift the package to the top of the second belt conveyor 84 for feeding.

[0042] When a weighing error or a scanning error occurs, the external PLC controller will automatically control the second motor 82 to operate. The operation of the second motor 82 causes the mounting frame 83 to rotate, thereby adjusting the conveying direction of the second belt conveyor 84. In this case, the erroneous packages can be transported to a specific location without stopping the machine, thereby effectively improving the sorting efficiency.

[0043] It is worth noting that the external PLC controller disclosed in the above embodiment is specifically a Siemens S7-200. The first belt conveyor 2 and the second belt conveyor 84 can use a 01-type chain conveyor, and the first motor 3 and the second motor 82 can use a 1LE0003 three-phase asynchronous motor. The electric telescopic rod 71 can use a TGC-A high-thrust electric telescopic rod. The weighing sensor 51 can use a JLBU-1 weighing sensor. The express code scanner 92 can be freely configured according to the actual application scenario, and the express code scanner 92 can use an existing mature product. The external PLC controller controls the first belt conveyor 2, the second belt conveyor 84, the first motor 3, the second motor 82, and the electric telescopic rod 71 using methods commonly used in the prior art.
