These steering mechanisms 310 are driven by separate rotary motors 315, respectively. That is, each steering mechanism 310 can steer independently. Meanwhile, the endless drive belts of these steering mechanisms 310 are driven by drive belts 314, respectively. The drive belt 314 of each steering mechanism 310 is drivably coupled to the drive shaft 313 . That is, each drive belt 314 is drivably coupled to the drive motor 312 via the drive shaft 313 so that the endless drive belts of all steering mechanisms 310 are driven by the drive motor 312 only.

Further, referring to FIG. 5 , the sorting device 31 of the present disclosure is provided with a generally rectangular outer frame 300 . The inner frame 311 as shown in FIG. 4 and various components provided thereon are installed in the outer frame 300 . The top of the outer frame 300 is provided with five circular openings for accommodating five steering mechanisms 310 . In the assembled state shown in Figure 5, the top surface of the steering bracket 317 is substantially flush with the top of the outer frame 300, and the endless drive belt protrudes slightly outward from the top of the outer frame 300 to facilitate contact with the cargo.

In addition, referring to FIG. 1 again, two conveying devices 40 may be arranged on the left and right sides of the sorting module 30, ie, on both sides in a direction perpendicular to the conveying direction of the goods, so as to convey the sorted goods to the sorting module 30. Pick a location. Here, the two conveyors 40 can relate to the same sorting position or to two different sorting positions. That is to say, the two transfer positions 40 can transfer the sorted goods to two different locations in the same sorting position, or can respectively direct the sorted goods to different sorting positions according to the goods transfer requirements. As shown, the conveyor 40 may be a roller conveyor comprising a set of rollers arranged side by side. Of course, the invention is not so limited, and various modifications to the number, location, and type of conveyors should also fall within the scope of this disclosure.

Hereinafter, specific operations of the cargo sorting apparatus of the present disclosure will be described. 6-9 are schematic diagrams of the operation process of the goods sorting apparatus according to the present disclosure, wherein FIG. 6 shows a situation in which two goods side by side are not sorted, and FIGS. 7-8 show a situation in which two goods side by side are not sorted. One is sorted, and Figure 9 shows the case where both loads side by side are sorted.

The cargo sorting apparatus of the present disclosure allows cargo to be conveyed side-by-side. Although the goods shown in the drawings are neatly arranged side by side on the conveyor belt, the goods conveyed side by side may also be staggered in the direction of goods conveyance. When the goods are sorted, the goods 100 (eg 100A, 100B, 100C, 100D, 100E, 100F) are first conveyed by the first conveyor belt 10 at the starting position. When the goods 100 pass the position of the scanning module 20 , the scanning module 20 performs image acquisition and information scanning on the goods 100 , and transmits the obtained images and scanning information to the control unit 60 . The control unit 60 can determine the sorting position and size of the goods based on the obtained images and scanning code information, and can determine whether the goods need to be sorted here according to the scanning code information.

As shown in FIG. 7 , when it is determined by scanning the code information that the goods 100A and 100B are not to be sorted here, the control unit 60 will not control the steering mechanism 310 of the sorting module 30 to perform a steering action. Thereby, the goods 100A and 100B will be transferred to the second conveyor belt 50 through the endless drive belt of the steering mechanism 310 .

Referring to Figure 8, goods 100C and 100D are conveyed side by side on a conveyor belt. When it is determined that the goods 100C do not need to be sorted here, but the goods 100D need to be sorted here, according to the size of the goods 100D and the position on the conveyor belt, the designated steering mechanism 310 is controlled to make a steering action , to transfer the goods 100D to the conveyor 40 . For example, the control unit 60 first determines the steering mechanisms 310 involved when the goods 100D pass through the sorting module, and controls the steering mechanisms 310 to turn toward the conveying device 40 , so that the goods 100D can be conveyed to the conveying device 40 . Optionally, additional conveyor belts may be provided at the end of the conveyor 40 to receive and continue to convey goods sorted there.

Preferably, there is a certain interval between two adjacent goods at the front and rear, and the interval is sufficient to ensure that when the preceding goods are diverted and conveyed by the diverting mechanism 310, the following goods that do not need to be sorted will not be diverted. Mechanism 310 turns to delivery. Preferably, an acceleration section or an accelerator may be provided before the goods are conveyed to the first conveyor belt 10, so as to ensure the interval between two adjacent goods in the front and rear by increasing the speed of the conveyor belt. In addition, the first conveyor belt 10 itself can also serve as an accelerator to ensure the above-mentioned interval.

Meanwhile, since the turning mechanism 310 of the sorting module of the present disclosure can be turned individually, when the two goods 100C and 100D are adjacent in the width direction of the conveyor belt, the sorting module 50 of the present disclosure can only make The diverting mechanism 310 related to the cargo 100D required to be sorted is turned, while the cargo 100C not to be sorted is maintained to continue to be transported in the cargo transport direction. Therefore, even when a plurality of goods are conveyed side by side, the sorting module 50 of the present disclosure can accurately sort the designated goods while maintaining other goods to continue to be conveyed onward. Therefore, the present disclosure can allow goods to be conveyed side-by-side, thereby maximizing the efficiency of conveying and sorting the goods.

In addition, each diverting mechanism 310 is controlled such that when the goods required to be sorted pass through the diverting mechanism 310, the diverting mechanism 310 is immediately restored to its original position so as not to affect the subsequent delivery of the goods.

Figure 9 shows the situation in which both loads side by side are sorted. As shown in FIG. 9 , when two goods 100E and 100F arranged side by side are sorted at the same time, the control unit 60 controls the designated steering mechanism 310 to make a steering action according to the size of the goods 100E and 100F and the position on the conveyor belt, The goods 100E and 100F are thus diverted to the conveyor 40, respectively.

In particular, in the present disclosure, each steering mechanism 310 can be steered within a predetermined angle range based on the conveying direction of the goods. For example, the steering mechanism 310 can be steered left or right within a range of 0-90 degrees based on the conveying direction of the goods, so that the goods thereon can be conveyed left or right as needed to achieve the desired sorting.

Although the present disclosure has been described in conjunction with the above-described embodiments, it is apparent that the scope of the present disclosure is not limited to the above-described embodiments. Certain components of the above-described embodiments of the present disclosure can be recombined to form new embodiments. Accordingly, those skilled in the art will recognize that various modifications, additions and substitutions are possible, without departing from the spirit and scope of the present disclosure as disclosed in the appended claims.
