[0032] Referring to Figure 2 , in the embodiment, the plurality of conveying branch lines 2 and the conveying main line 1 are parallel to each other, so that the space utilization is greatly improved, and the unnecessary area occupied by too many conveying branch lines is reduced.

[0033] Referring to Figure 2 ​As shown, the conveying main line 1 includes a high-speed conveying section 11, a medium-speed conveying section 12, a low-speed conveying section 13, a queuing conveying section 14, and a horizontal conveying section 15. The high-speed conveying section 11, the medium-speed conveying section 12, and the low-speed conveying section 13 are connected end to end. The horizontal conveying section 15 is arranged between the low-speed conveying section 13 and the queuing conveying section 14 and is drivingly connected to the medium-speed conveying section 12 to synchronize the movement of the horizontal conveying section 15 and the low-speed conveying section 13. In this embodiment, the high-speed conveying section 11, the medium-speed conveying section 12, and the low-speed conveying section 13 preferably adopt belt conveyors, and the queuing conveying section 14 preferably adopts an accumulation roller conveyor. The high-speed conveying section 11, the medium-speed conveying section 12, and the low-speed conveying section 13 sequentially and uniformly convey the packages onto the horizontal conveying section 15, and the horizontal conveying section 15 sequentially conveys the packages onto the queuing conveying section 14.

[0035] The structure and principle of the high-speed conveying section 11, the medium-speed conveying section 12, the low-speed conveying section 13, the queuing conveying section 14, and the horizontal conveying section 15 are known in the art and will not be repeated here.

[0036] Further, the high-speed conveying section 11, the medium-speed conveying section 12, and the low-speed conveying section 13 in this embodiment adopt a multi-stage speed reduction mode, i.e., the conveying speed gradually decreases from high speed to low speed, thereby ensuring the smooth transition of the packages during conveying and achieving efficient and safe package conveying.

[0037] In combination with Figure 2 , Figure 3As shown, the input end of the high-speed conveying section 11 is provided with a transition plate 111, and one side of the high-speed conveying section 11 is provided with a second inclined support 112, and a plurality of power rollers 113 are rotatably arranged between the high-speed conveying section 11 and the transition plate 111, so that the plurality of power rollers 113 and the high-speed conveying section 11 are integrally designed, thereby reducing the gap therebetween, and the angle between the axis of the power roller 113 and the high-speed conveying section 11 is 30°-60°, preferably 45°, thereby avoiding the rolling of the high-speed package after speed reduction and stall, and the second inclined support 112 is fixedly installed with a power driving device, and a servo motor is preferably adopted in the embodiment, and the output shaft and the plurality of power rollers 113 are drivingly connected, so that after the package of the balance sorting machine passes through the plurality of power rollers 113, the package is sent into the high-speed conveying section 11 by rotating the plurality of power rollers 113 driven by the power driving device, thereby avoiding the rolling caused by the change of the package form when the package vertically transitions.

[0038] Referring to Figures 4-5 As shown, further, the merging device 5 includes a plurality of rollers 51, a plurality of rollers 52, and a driving device 53, and one side of the medium-speed conveying section 12 is provided with a first inclined support 121, so that one end of the plurality of rollers 51 is rotatably connected with the first inclined support 121, and the other end is rotatably connected with the side wall of the medium-speed conveying section 12, thereby forming an integrated design between the plurality of rollers 51 and the medium-speed conveying section 12, reducing the gap therebetween, and the structure is simpler, thereby effectively reducing the equipment cost, and the plurality of rollers 52 are rotatably arranged on the first inclined support 121 along the length direction, and the driving device 53 is fixedly installed on the outside of the first inclined support 121, and a speed reducer is preferably adopted as the driving device 53 in the embodiment, and a pulley is fixedly installed on the output shaft of the driving device 53, and the plurality of rollers 52 are tensioned with a driving belt 54 drivingly connected with the driving device 53, and the surface of the driving belt 54 abuts against the plurality of rollers 51, so that when the driving device 53 drives the driving belt 54 to rotate, the plurality of rollers 52 are driven to rotate by the frictional force of the surface of the driving belt 54, thereby merging the package on the conveying branch line 2 into the medium-speed conveying section 12, so that the package on the conveying branch line 2 and the package on the conveying main line 1 are merged.

[0039] Preferably, the input end of the medium-speed conveying section 12 is provided with a first parcel detection module, and the confluence device 5 is provided with a second parcel detection module at the confluence position of the confluence device 5 and the medium-speed conveying section 12. In the embodiment, the first parcel detection module and the second parcel detection module preferably adopt photoelectric sensors. The first parcel detection module is used to monitor whether there is a parcel at the input end of the medium-speed conveying section 12, and the second parcel detection module is used to detect whether the parcel reaches a specified position. When the second parcel detection module detects the parcel on the confluence device 5, feedback is given to the PLC unit. At this time, if the first parcel detection module detects that there is no parcel at the input end of the medium-speed conveying section 12, the PLC unit causes the confluence device 5 to merge the parcel into the medium-speed conveying section. If the first parcel detection module detects that there is a parcel passing through the input end of the medium-speed conveying section 12, the confluence device 5 waits for a set time before sending the parcel of the conveying branch line 2 into the medium-speed conveying section 12. In this way, the parcel on the confluence device 5 is prevented from colliding with the parcel of the conveying main line 1, thereby preventing the parcel from being damaged.

[0040] The connection relationship between the PLC unit and the first parcel detection module, the second parcel detection module, and each conveying section is a prior art, which will not be repeated here.

[0041] In combination with FIGS. 1-3, Figure 7 、 Figure 8 Further, the medium-speed conveying section 12 is provided with a deviation rectifying device 3. The deviation rectifying device 3 includes a deviation rectifying bracket 31 and a rolling deviation rectifying portion 32. In the embodiment, the deviation rectifying bracket 31 is a pair of brackets, and the two deviation rectifying brackets 31 are not parallel to each other. The medium-speed conveying section 12 is provided with reserved hole positions for assembling the deviation rectifying bracket 31. Therefore, the deviation rectifying bracket 31 is fixed to the medium-speed conveying section 12 by bolts, and the rolling deviation rectifying portion 32 is arranged in the deviation rectifying bracket 31. In the embodiment, the rolling deviation rectifying portion 32 includes a first deviation rectifying roller group and a second deviation rectifying roller group. The first deviation rectifying roller group and the second deviation rectifying roller group are in a V shape and abut against the lower belt 120 of the medium-speed conveying section 12, so that the rolling deviation rectifying portion 32 rectifies the belt on the medium-speed conveying section 12, avoids the belt deviation of the medium-speed conveying section 12, and improves the conveying efficiency and safety.

[0042] Specifically, the first straightening roller assembly includes a first straightening roller 321, and the second straightening roller assembly includes a second straightening roller 322. The first straightening roller 321 and the second straightening roller 322 are rotatably mounted on the straightening support 31. The first straightening roller 321 and the second straightening roller 322 are not parallel to each other. In this embodiment, the included angle between the first straightening roller 321 and the second straightening roller 322 is 28°-32°, preferably 30°, and the first straightening roller 321 and the second straightening roller 322 are not parallel to each other. Both rollers 22 and 322 are in contact with the lower surface of the belt of the medium-speed conveyor section 12, so that the first correction roller 321 and the second correction roller 322 rotate under the drive of the belt of the medium-speed conveyor section 12. Thus, the first correction roller 321 and the second correction roller 322 continuously squeeze the belt of the medium-speed conveyor section 12 towards the center, thereby preventing the belt on the medium-speed conveyor section 12 from deviating to the sides during the conveying process. This realizes the automatic correction of the medium-speed conveyor section 12 and greatly improves the stability of package conveying.

[0043] Reference Figure 11 , Figure 12 As shown, even better, the low-speed conveying section 13 is provided with several side plates 131 on both sides, and each side plate 131 is fixedly connected to the other side plates by connecting blocks 1312. Furthermore, the surface of the side plates 131 is provided with several reinforcing plates 1311 at intervals along the conveying direction of the package, thereby greatly enhancing the body strength of the low-speed conveying section 13, achieving a large span load-bearing capacity, effectively improving space utilization efficiency, and significantly reducing the difficulty and intensity of installation.

[0044] Reference Figure 11 , Figure 13As shown, the horizontal conveying section and the low-speed conveying section 13 in the embodiment are both composed of a belt, a plurality of transmission shafts and a driving motor. The structure and principle are the existing technology, which is not repeated here. In order to ensure that the conveying speed of the horizontal conveying section is consistent with the conveying speed of the low-speed conveying section 13, a first synchronous wheel 132 is arranged on the transmission shaft of the low-speed conveying section 13, and a second synchronous wheel 153 is arranged on the transmission shaft of the horizontal conveying section 15. The first synchronous wheel 132 and the second synchronous wheel 153 are drivingly connected with a connecting belt 151. The side walls of the low-speed conveying section 13 and the horizontal conveying section 15 are fixedly provided with a tensioning bracket 154. A tensioning slide 155 is arranged below the tensioning bracket 154 in a lifting manner. A strip-shaped slot is formed in the side wall of the tensioning slide 155. A connecting hole is arranged on the side wall of the tensioning bracket 154. The strip-shaped slot of the tensioning slide 155 and the connecting hole of the tensioning bracket 154 are fixedly connected through a locking part. In the embodiment, the locking part is preferably a screw and a nut, so that the height of the tensioning slide 155 can be adjusted. A tensioning wheel 152 is rotatably arranged at the bottom of the tensioning slide 155 and abuts against the connecting belt. The tensioning wheel 152 is driven by the tensioning slide 155 to lift or lower, so as to adjust the tightness of the connecting belt 151 and ensure that the linkage between the horizontal conveying section 14 and the low-speed conveying section 13 is more stable.

[0045] With reference to Figure 9 , Figure 14 As shown further, the input end of the low-speed conveying section 13 is fixedly provided with a transition frame 132. When the low-speed conveying section is installed in an inclined manner, the gap between the low-speed conveying section 13 and the medium-speed conveying section 12 is too large, or the centers of the two are not parallel. The transition frame 132 can prevent the package from falling out of the gap of the conveying main line 1 due to the too large gap between the low-speed conveying section 13 and the medium-speed conveying section 12. In order to prevent the package from being stuck in the gap between the low-speed conveying section 13 and the medium-speed conveying section 12, a transition roller 1321 is rotatably arranged on the transition frame 132. The package can be smoothly sent from the medium-speed conveying section 12 to the low-speed conveying section 13, so as to prevent the package from being stuck or blocked.

[0046] It is further explained that the transition frame 132 and the transition roller 1321 in the embodiment are not limited to be arranged on the low-speed conveying section 13, but can also be arranged on the high-speed conveying section 11 and the medium-speed conveying section 12, so as to ensure that the assembled conveying main line is more smooth in the conveying process.
