The merging belt conveyor 130 is connected and communicated with the outlet end of the second accumulation belt conveyor 120. In this embodiment, the structure of the merging belt conveyor 130 is similar to or the same as the structure of the straight belt conveyor 110. It should be noted that the number of the straight belt conveyors 110 can be selected according to the actual required length of the main conveyor line 100.

[0040] As Figure 1As shown, the conveying branch line 300 includes a plurality of first straight roller machines 310. Adjacent first straight roller machines 310 are connected and communicated through a first turning roller machine 320. The outlet end of the conveying branch line 300 includes a third accumulation belt conveyor 330, and the outlet end of the third accumulation belt conveyor 330 is communicated with the merging device 500. The setting of the first turning roller machine 320 can improve the diversity of the layout track of the conveying branch line 300, facilitating the setting of the position of the separation and merging between the conveying branch line 300 and the conveying main line 100. It should be noted that the number of the first straight roller machines 310 and the first turning roller machines 320 can be selected according to the actual required length of the conveying branch line 300 and the separation and merging positions. In this embodiment, the conveying branch line 300 includes at least two first straight roller machines 310 and two first turning roller machines 320. One of the first turning roller machines 320 is connected and communicated between the two first straight roller machines 310. One of the first straight roller machines 310 is communicated with the diverting device 400, and the other first straight roller machine 310 is connected and communicated with the inlet end of the third accumulation belt conveyor 330 through the other first turning roller machine 320.

[0041] As Figure 1 shown, the diverting device 400 includes a pendulum wheel mechanism 410 and also includes a plurality of diverting roller machines 420 correspondingly communicated with the inlet ends of a plurality of conveying branch lines 300. The pendulum wheel mechanism 410 is connected and communicated with the diverting roller machines 420. In this embodiment, the conveying main line 100 includes two straight belt conveyors 110. The pendulum wheel mechanism 410 is arranged between the two straight belt conveyors 110 and is communicated with both of the two straight belt conveyors 110.

[0042] As Figure 1 shown, the merging device 500 includes a plurality of merging narrow belt machines correspondingly communicated with the outlet ends of a plurality of conveying branch lines 300. When the conveying branch line 300 includes at least two, each merging narrow belt machine is connected and communicated with different positions of the merging belt conveyor 130, and the deviation rectifying device 600 is located between two adjacent merging narrow belt machines. It should be noted that the merging narrow belt machine is a prior art and will not be elaborated here.

[0043] In this embodiment, the conveying main line 100, the bar code scanning device 200, the conveying branch line 300, the diverting device 400, the merging device 500, and the weighing device 700 can all be controlled by the PLC controller. Specifically, the scanning mechanism 220 is communicatively connected with the PLC controller through an industrial computer.

[0044] The working principle of a bin conveying system in this embodiment is as follows:

[0045] Place the bin at the barcode scanning device 200. The scanning mechanism 200 scans and reads the barcode on the bin. The industrial control computer transmits the barcode information obtained by the scanning mechanism 200 to the PLC controller. The weight information obtained by the weighing device 700 is also transmitted to the PLC controller. The PLC controller allocates the conveying line that the bin is to enter according to the barcode information and the weight information. Specifically, the bin is made to enter the main conveying line 100 or the branch conveying line 300 by controlling the pendulum wheel mechanism 410. At the confluence belt conveyor 130, when the conveyor belt of the confluence belt conveyor 130 runs off to one side, since both the first roller 621 and the second roller 622 are in contact with the lower belt 131 of the confluence belt conveyor 130, the first roller 621 and the second roller 622 can offset the conveyor belt in the direction opposite to the deviation direction, playing a role in deviation correction.

[0046] Embodiment 2

[0047] This embodiment is the second embodiment of a bin conveying system. This embodiment is similar to Embodiment 1, and the difference lies in that, as Figures 5 to 7 shown, the rolling deviation correction part 620 includes a plurality of third rollers 623 and a plurality of fourth rollers 624 connected to the mounting frame 610. The plurality of third rollers 623 are arranged and parallel to each other. The plurality of fourth rollers 624 are arranged and parallel to each other. The third rollers 623 and the fourth rollers 624 are not parallel to each other, and both the third rollers 623 and the fourth rollers 624 are in contact with the lower belt 131 of the confluence belt conveyor 130. In this embodiment, the plurality of third rollers 623 and the plurality of fourth rollers 624 are symmetrically arranged. One end of the third roller 623 is close to the outer frame 133 on one side of the machine frame. The other end of the third roller 623 is close to one end of the fourth roller 624. The other end of the fourth roller 624 is close to the outer frame 133 on the other side of the machine frame. Specifically, the included angle b between the third roller 623 and the axial direction of the roller of the confluence belt conveyor 130 is 14° - 16°. The included angle c between the fourth roller 624 and the axial direction of the roller of the confluence belt conveyor 130 is 14° - 16°. And, the first roller 623 is inclined from the end close to the inner side of the conveyor belt to the end close to the outer side of the conveyor belt along the bin conveying direction of the confluence belt conveyor 130, as Figure 7 shown.

[0048] Specifically, waist-shaped holes 612 are provided at both ends of the mounting frame 610. The mounting frame 610 is connected to the outer frame 133 through the waist-shaped holes 612. In this embodiment, the extending direction of the waist-shaped holes 612 is parallel to the bin conveying direction of the confluence belt conveyor 130. The setting of the waist-shaped holes 612 can facilitate the fine adjustment of the position of the deviation correction device 600 on the confluence belt conveyor 130.

[0049] The working principle of a bin conveying system in this embodiment is as follows:

[0050] At the confluent belt conveyor 130, since both the third roller 623 and the fourth roller 624 are in contact with the lower belt 131 of the confluent belt conveyor 130, the third roller 623 and the fourth roller 624 will continuously squeeze the conveyor belt towards the middle. When the belt of the confluent belt conveyor 130 runs off track, the contact area between the conveyor belt and the third roller 623 and the fourth roller 624 increases, and a greater force will squeeze the conveyor belt towards the middle, playing a role in rectifying the deviation.

[0051] Embodiment Three

[0052] This embodiment is the third embodiment of a bin conveying system. This embodiment is similar to Embodiment One, the difference being that, as Figure 8 and Figure 9 shown, the rolling deviation rectifying part 620 includes a plurality of fifth rollers 625 connected to the mounting frame 610. The plurality of fifth rollers 625 are arranged in parallel and are parallel to the rollers of the confluent belt conveyor 130. The fifth rollers 625 are located between the lower belt 131 and the upper belt 132 of the confluent belt conveyor 130, and the fifth rollers 625 are in contact with the upper belt 132.

[0053] Specifically, the mounting frame 610 is connected to the fuselage 134 of the frame of the confluent belt conveyor 130. The mounting frame 610 is provided with a plurality of grooves, and the roller shafts of the fifth rollers 625 are clamped in the grooves, and the distances between adjacent grooves are equal.

[0054] The working principle of a bin conveying system in this embodiment is as follows:

[0055] At the confluent belt conveyor 130, since the fifth rollers 625 are in contact with the upper belt 132 of the confluent belt conveyor 130, it can reduce the hard friction between the conveyor belt and the fuselage 134, avoid the deviation of the conveyor belt caused by wrapping and extrusion, and can play a role in rectifying the deviation.
