In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance. And in the description of the scheme, with reference to the operator, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0037] The deflection wheel sorting unit disclosed in the present application will be described below in conjunction with the drawings, as shown in the drawings Figure 1 The base plate 100 can be various possible shapes, for example, it can be rectangular or regular hexagonal, regular octagonal, etc., and more preferably square.

[0038] As shown in the drawings Figure 1 At least one clamping notch 110 extending straight from the top surface 140 to the bottom surface 150 is formed at each side 130 of the base plate 100, and preferably two clamping notches 110 are formed at each side, which are located near the top corners of the base plate 100. The clamping notches 110 are trapezoidal with narrow outer ends and wide inner ends. Of course, in other embodiments, the clamping notches 110 can also be other shapes, such as rectangular or large semicircular, etc. And in order to facilitate connection with other structures, mounting holes 120 are formed at each top corner of the base plate 100.

[0039] As shown in the drawings Figure 1 , the drawings Figure 2 The center of the base plate 100 is provided with a deflection seat 200 that can rotate, and the projection of the top surface of the base plate 100 does not protrude outside the base plate 100. Specifically, a bearing 400 is coaxially arranged at the center of the base plate 100, which includes a coaxial upper circular ring 410, a lower circular ring 420 and a circle of balls 430 between them. This bearing structure can better support the deflection seat 200. The bearing 400 is fixed in the circular groove 160 at the center of the base plate 100.

[0040] And as shown in the drawings Figure 2As shown, a connecting sleeve 500 is inserted into the central hole of the bearing 400, and the support plate of the connecting sleeve 500 is attached to the top of the upper ring 410. The central shaft 210 of the deflection seat 200 is inserted into the insertion hole of the connecting sleeve 500, so that the deflection seat 200 can rotate relative to the base plate 100.

[0041] As attached Figure 2 As shown, a circular mounting base 220 is coaxially arranged on the central shaft 210. The circumferential surface of the circular mounting base 220 does not protrude beyond the edge of the base plate. A mounting groove 230 is formed on the circular mounting base 220. The mounting groove 230 includes a rectangular deep groove 231 and rectangular shallow grooves 232 symmetrically arranged at both ends of the rectangular deep groove 231.

[0042] As attached Figure 2 As shown, the deflection seat 200 is provided with an electric roller 300 that partially protrudes beyond its top. The two ends 310 of the support shaft of the electric roller 300 are mounted on the two rectangular deep grooves 231 and cannot rotate on its own. The roller surface of the electric roller 300 has a plurality of grooves 320 parallel to its axis. The grooves 320 can be arc-shaped grooves or rectangular grooves. The base plates of the central shaft 210 and the circular mounting seat 220 have coaxial and interconnected wire holes to facilitate the wiring of the electric roller.

[0043] Further details are attached. Figure 2 As shown, a circular cover plate 240 is provided on the circular mounting base 220. The circular cover plate 240 has a clearance hole 241 corresponding to the position of the electric roller 300. An annular boss 242 is formed on the bottom surface of the circular cover plate 240. The annular boss 242 is close to or in contact with the two ends 310 of the support shaft of the electric roller 300, so that the circular cover plate 240 can effectively restrict the electric roller 300.

[0044] Example 2

[0045] This embodiment discloses a deflecting wheel sorting machine, as shown in the attached figure. Figure 3 - Appendix Figure 4 As shown, the system includes a set of deflection wheel sorting units 1 as described in the above embodiments and a swing drive mechanism 2 for driving the deflection wheel sorting units 1 to swing. The number and layout of the multiple deflection wheel sorting units 1 can be designed as needed. In this embodiment, the deflection wheel sorting units 1 are arranged in five rows and five columns, so that the conveying surface of the entire deflection wheel sorting machine is square.

[0046] As attached Figure 4As shown, the deflector wheel sorting units 1 and the swing driving mechanism 2 are arranged on a frame 6, which can be various possible structures, and in the preferred embodiment, the frame 6 comprises four support columns 61, two support columns 61 on the same side are provided with a cross beam 65, four L-shaped plates 62 are arranged in a square shape on the four support columns 61, and a top cover 63 is arranged on the L-shaped plates 62, and the top plate of the top cover 63 is formed with a avoiding through hole 64 for the installation of each deflector wheel sorting unit 1.

[0047] The outermost circle of the plurality of deflector wheel sorting units 1 are connected to the flat plate of the L-shaped plate 62 through bolts passing through the mounting holes 120 on the bottom plate 100, and the adjacent deflector wheel sorting units 1 are connected through the clamping blocks 3 inserted into the clamping notches 110 opposite to their positions, the clamping blocks 3 are butterfly-shaped, and the clamping blocks 3 and the bottom plate can be assembled in an interference fit manner, so as to effectively ensure the stability of the assembly between the plurality of deflector wheel sorting units 1, especially the structural stability between the deflector wheel sorting units 1 not connected to the L-shaped plate 62.

[0048] Of course, in other embodiments, the adjacent deflector wheel sorting units 1 can be fixed by screwing, welding or other methods, so as to ensure the structural integrity. In order to reduce the blank area between the electric rollers and avoid material jamming, as shown in the accompanying drawings, Figure 5 As shown, the region 4 between the adjacent four deflector wheel sorting units is provided with a universal ball 5 with a top point flush with the top surface of the electric roller 300, and the universal ball 5 is fixed on the top plate of the top cover 63.

[0049] As shown in the accompanying drawings, Figure 4 , the accompanying drawings, Figure 6 As shown, the deflector seats 200 of all the deflector wheel sorting units 1 are driven to swing by one swing driving mechanism 2. The swing driving mechanism 2 comprises a motor 21 fixed on a mounting plate 66, the mounting plate 66 is fixed between two cross beams 65, the motor 21 can be a reduction motor, or a common motor connected with a reduction motor, the power output shaft of which vertically penetrates the mounting plate 66 and is connected with one end of a swing arm 22, the other end of the swing arm 22 is pivotally connected with a transmission plate 23, the two ends of the transmission plate 23 are vertically provided with two parallel driving long plates 24, one end of each driving long plate 24 is pivotally connected with one end of a row or a column of followers 25, the other end of the row or column of followers 25 is fixed on the central shaft 210 or the connecting sleeve 500 of the deflector seat 200 of the row or column of deflector wheel sorting units 1 and located below the bottom plate 100.

[0050] The swing drive mechanism 2 also includes multiple driven plates 26 parallel to the drive plate 24. Each driven plate 26 is pivotally connected to a row or column of driven members 25. The driven plates 26, the drive plate 24, and the driven plates 26 are connected as a whole by a connecting plate 27. Therefore, when the motor 21 drives the swing arm 22 to rotate, the swing arm 22 drives the transmission plate 23, which in turn drives the drive plate 24, and then drives multiple driven plates 26 through the connecting plate 27. This, in turn, drives multiple deflection seats 200 to swing through the rotation of the driven members 25.

[0051] The swing drive mechanism 2 can not only drive multiple deflection seats 200, but also effectively support the deflection wheel sorting unit 1, ensuring the stability of their assembled structure.

[0052] Example 3

[0053] This embodiment discloses a deflection wheel sorting system, as shown in the attached figure. Figure 7 As shown, the system includes any of the aforementioned deflector wheel sorting machines 1000. There are multiple deflector wheel sorting machines 1000, with adjacent machines connected by a conveyor 2000. The input end of the first deflector wheel sorting machine is connected to an input line 3000, and each adjacent deflector wheel sorting machine has chutes 4000 on both sides.

[0054] Example 4

[0055] This solution further discloses a package supply system, as shown in the attached document. Figure 8 As shown, the deflection wheel sorting machine 30 of the above embodiment is included. The three output ends of the deflection wheel sorting machine 30 are connected to three packing stations 10, and the input end of the deflection wheel sorting machine 30 is connected to a six-sided barcode scanning conveyor line 40.

[0056] As attached Figure 8 Appendix Figure 9 As shown, the three feeding stations 101, 102, and 103 are of equal length and arranged in parallel. Each feeding station 10 can be a known multi-segment feeding station. However, compared to existing feeding stations, the scanning device can be omitted at the feeding station 10 in this solution. The other structures are the same as existing feeding stations and will not be described in detail here. In a preferred embodiment, the weighing section can also be omitted at the feeding station 10, and a weighing section can be set at the six-sided scanning conveyor line 40, which can effectively reduce the number of weighing sections.

[0057] The three feeding stations 101 are connected to the three output ends of the deflector sorter 30 via three transfer conveyor lines 20. The three transfer conveyor lines 20 are arranged in an "E" shape, although they can also be arranged in other forms. See attached diagram for details. Figure 2As shown, the transfer conveyor line 201 connected to the middle feeding platform 101 can be a straight-extending conveyor 2011. In this case, the extension direction of the feeding platform 101 is preferably perpendicular or nearly perpendicular to the running direction of the trolley loop. In another embodiment, the transfer conveyor line 201 may also include a straight-extending conveyor 2011 and a turning machine 2012 connected to its rear end. In this case, the extension direction of the feeding platform 101 maintains an acute angle with the running direction of the trolley loop.

[0058] As attached Figure 9 Appendix Figure 10 As shown, the transfer conveyor lines 202 and 203 connected to the bag-feeding platforms 102 and 103 on both sides have the same structure, each including at least a first turning machine 2021 and 2031 and a first linear conveyor 2022 and 2032 connected sequentially from the deflection wheel sorter to the bag-feeding platform. In a more preferred embodiment, the rear end of the first linear conveyor 2022 and 2032 can also be connected to a second turning machine 2023 and 2033. Of course, in other embodiments, the front of the first turning machine 2021 (defined as the position the item passes through first during the bag-feeding system transport process as the front and the position it passes through last as the rear) can also be connected to a second linear conveyor 2024 and 2034 perpendicular to the transport direction of the linear conveyor in the transport direction.

[0059] Additionally, if the height of the conveying surface of the transfer conveyor line 20 is level with or slightly lower than the height of the conveying surface of the deflector wheel sorter 30, then the deflector wheel sorter 30 is directly connected to the conveyor 2011. If there is a significant height difference between the conveying surface of the transfer conveyor line 20 and the conveying surface of the deflector wheel sorter 30, then the transfer conveyor line 20 and the deflector wheel sorter 30 need to be connected via a chute. In this case, as shown in the attached... Figure 10 As shown, the second linear conveyors 2024 and 2034 of the transfer conveyor lines 202 and 203 can be replaced by chutes.

[0060] The layout of the three transfer conveyor lines 20 is one of the main innovations. However, the specific structures of the conveyors and turning machines of each section of the transfer conveyor line 20 are known technologies and are not innovations of this solution, so they will not be described in detail here.

[0061] As attached Figure 8As shown, the six-surface code scanning conveyor 40 connected with the input end of the deflection wheel sorter 30 is used to read the bar code or two-dimensional code on the surface of the article by a plurality of image acquisition devices (not shown in the figure), and the specific structure thereof can be designed as required, for example, it can be the structure disclosed in the applications with the application numbers 201922221682.X and 201921212579.2. Further, a section of the six-surface code scanning conveyor 40 is a weighing section, so that the weighing section at the package supply table 10 can be effectively reduced.

[0062] In work, after the package is placed on the six-surface code scanning conveyor 40 to obtain routing information, the package is conveyed to the deflection wheel sorter 30, and the deflection wheel sorter 30 alternately places the package into the three package supply tables.

[0063] The present application has various embodiments, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present application.
