Competition in the logistics and warehousing markets is becoming increasingly fierce, and automated equipment is becoming increasingly important in these fields. Sorting is a key part of logistics and warehousing. To improve sorting efficiency and simplify pickup operations, intelligent sorting equipment that can automatically sort goods is gradually being used.

[0003] There are two driving methods in the existing sorting equipment. The first is to set a power source at one end of the sorting equipment and a tensioning component at the other end, and drive the entire sorting equipment to perform horizontal rotation through a chain drive. The second is to use a linear motor multi-point drive. Both of these driving methods have obvious disadvantages. With the first method, when the overall length of the equipment is too long, it is difficult to drive the entire sorting equipment by the power source at the end alone, so the length of this sorting equipment is limited.

[0040] Figure 2 shows a schematic diagram of the structure of a rotary seeding mechanism 130 according to one embodiment of the present invention, and Figure 3 shows a schematic diagram of the assembly structure of a module vehicle 135 and an intermediate section 132 according to one embodiment of the present invention. As shown in Figure 2 , the rotary seeding mechanism 130 includes a fixed drive section 131, an intermediate section 132, an intermediate drive section 133, a floating drive section 134, and a module vehicle 135.

[0041] In one embodiment of the present invention, the rotary seeding mechanism 130 includes a chain (not shown), multiple module carts 135, a fixed drive segment 131, a floating drive segment 134, multiple intermediate segments 132, and at least one intermediate drive segment 133. The module carts 135 are fixedly connected to the chain and can retrieve goods from the upper packaging platform and transport them under the drive of the chain. The fixed drive segment 131 can drive the chain to drive the module carts 135 to perform horizontal rotational motion. The floating drive segment 134 and the fixed drive segment 131 are located at opposite ends of the rotary seeding mechanism 130, and the floating drive segment 134 can tension the chain. Multiple intermediate segments 132 are distributed between the fixed drive segment 131 and the floating drive segment 134 and are adjacent to the material box. The intermediate segments 132 include intermediate segment frames that can guide the movement direction of the module carts 135. The intermediate drive segments 133 are arranged between the multiple intermediate segments 132 and can drive the chain to rotate.

[0042] In one embodiment of the present invention, the rotary seeding system 130 further includes: multiple anchors and multiple chain guides. The anchors are connected to the fixed drive segment 131, the intermediate segment 132, the intermediate drive segment 133, and the floating drive segment 134 to provide support; the multiple chain guides are fixed to the fixed drive segment 131, the intermediate segment 132, the intermediate drive segment 133, and the floating drive segment 134 to support the chain.

[0043] In one embodiment of the present invention, the rotary distribution system 130 also includes: a trolley bar assembly, which is fixedly connected to the fixed drive section 131, the intermediate section 132, the intermediate drive section 133 and the floating drive section 134, and is slidingly connected to the module vehicle 135, and can provide power to the module vehicle 135.

[0044] FIG4 shows a schematic structural diagram of a fixed driving section 131 according to an embodiment of the present invention. As shown in FIG4 , the fixed driving section 131 includes a driving section welding frame 1311 , a driving sprocket 1312 , and a fixed power source 1313 .

[0045] In one embodiment of the present invention, the driving sprocket 1312 is fixed on the driving welding frame 1311 and connected to the chain; the fixed power source 1313 is fixed on the driving welding frame 1311 and can drive the above-mentioned driving sprocket 1312 to drive the chain to rotate.

[0046] In one embodiment of the present invention, the fixed power source 1313 can be implemented as a three-phase asynchronous motor or a servo motor, which has a higher cost-performance ratio than a linear motor.

[0047] Fig. 5 shows a schematic structural diagram of the middle section 132 according to an embodiment of the present invention. As shown in Fig. 5, the middle section 132 is composed of a middle section frame.

[0048] In one embodiment of the present invention, the rotary distribution mechanism 130 includes multiple intermediate sections 132. The number of intermediate sections determines the overall length of the device, the maximum number of modular carts, and, consequently, the distribution capacity. Workers can flexibly adjust the number of intermediate sections based on site conditions and distribution needs, and this is not a limitation of the present invention. It should be noted that the distribution capacity referred to herein refers to the maximum number of slots into which the device can distribute goods.

[0049] Figure 6 shows a schematic diagram of the structure of an intermediate drive section 133 according to one embodiment of the present invention, and Figure 7 shows a top view schematic diagram of the structure of the intermediate drive section 133 according to one embodiment of the present invention. As shown in Figures 6 and 7, the intermediate drive section 133 includes an intermediate sprocket 1331 and an intermediate power source 1332.

[0050] In one embodiment of the present invention, the intermediate sprocket 1331 is fixed on the intermediate section frame 1321 and offset to one side of the chain. The intermediate power source 1332 can drive the intermediate sprocket 1331 to rotate, so that the intermediate sprocket drives the chain to rotate.

[0051] In one embodiment of the present invention, power is transmitted between the intermediate power source 1332 and the intermediate sprocket 1331 via a chain and sprocket mechanism.

[0052] In one embodiment of the present invention, the intermediate sprocket 1331 and intermediate power source 1332 are fixed to the intermediate section frame 1321 of the intermediate section 132. Specifically, by adding the intermediate sprocket 1331 and intermediate power source 1332, the intermediate section 132 is transformed into the intermediate drive section 133. In another embodiment, the intermediate sprocket 1331 and intermediate power source 1332 can be fixed to a new frame of the same size as the intermediate section frame to form an intermediate drive section, which is then inserted between the two intermediate sections. Both approaches allow for flexible placement of the intermediate drive section 133 without affecting the overall layout of the equipment.

[0053] In one embodiment of the present invention, taking into account the difference in running speeds of the parallel chains on both sides of the sprocket due to the polygonal effect of the chain (the outline of the chain wrapped around the sprocket is not circular but polygonal), by setting the number of teeth of the intermediate sprocket 1331 to be less than the number of teeth of the driving sprocket 1312, the impact caused by the difference in running speeds of the parallel chains on both sides can be reduced.

[0054] In one embodiment of the present invention, the number of intermediate drive sections 133 depends on the output torque and power of the fixed power source 1313, the intermediate power source 1332, and the floating power source, as well as the number of module vehicles 135. When the output torque and power of each power source are constant, the more module vehicles 135 there are, the more intermediate drive sections there are.

[0055] In one embodiment of the present invention, if the number of intermediate drive segments 133 is an even number, the multiple intermediate drive segments 133 are evenly and uniformly distributed on both sides of the chain; if the number of intermediate drive segments is an odd number, the multiple intermediate segments are evenly distributed on both sides of the chain, and the number of intermediate drive segments arranged on one side is one more than the number on the other side.

[0056] In one embodiment of the present invention, the intermediate power source 1332 can be implemented as a three-phase asynchronous motor or a servo motor, which has a higher cost-effectiveness than a linear motor.

[0057] FIG8 shows a schematic structural diagram of a floating drive section 134 according to an embodiment of the present invention. As shown in FIG8 , the floating drive section 134 includes a tensioning sprocket 1341 , a sprocket accessory 1342 , a floating power source 1343 , an elastic component 1344 , and a tensioning welding frame 1345 .

[0058] In one embodiment of the present invention, the floating drive section 134 includes a tensioning mechanism, a floating power source 1343 connected to the tensioning mechanism, and a floating sprocket 1341. The floating sprocket 1341 is connected to the chain; the floating power source 1343 drives the floating sprocket 1341, which in turn rotates the chain, thereby cooperating with the fixed drive section 131 and the intermediate drive section 133 to drive the module vehicle 135. The tensioning mechanism drives the floating sprocket 1341 to tension the chain.

[0059] In one embodiment of the present invention, the tensioning mechanism includes a tensioning welding frame 1345, a sprocket assembly 1342, and an elastic component 1344. The sprocket assembly 1342 is connected to the floating sprocket 1341 and the floating power source 1343, and the sprocket assembly is fixed to the tensioning welding frame 1345. The elastic component 1344 is fixed to the tensioning welding frame 1345 and can drive the floating sprocket 1341 to tension the chain and cause the floating power source 1343 and the floating sprocket 1341 to float along a straight line.

[0060] In one embodiment of the present invention, the floating power source 1343 can be implemented as a three-phase asynchronous motor or a servo motor, which has a higher cost-effectiveness than a linear motor.

[0061] FIG9 shows a schematic structural diagram of an elastic component 1344 according to an embodiment of the present invention. As shown in FIG9 , the elastic component 1344 includes: a fixing seat 13441 , a long screw rod 13442 with a nut, a linear bearing 13443 , a spring 13444 , and a guide shaft 13445 .

[0062] In one embodiment of the present invention, the elastic assembly 1344 includes a fixed seat 13441, a spring 13444, a long screw rod 13442 with a nut, a plurality of guide shafts 13445, and a linear bearing 13443. The fixed seat 13441 is fixed to the tensioning welding frame 1345; the long screw rod 13442 with a nut is fixed to the fixed seat 13441; the spring 13444 is sleeved on the long screw rod 13442 with a nut, and one end of the spring 13444 abuts the sprocket assembly 1342 and the other end abuts the nut. Rotating the nut can compress the spring 13444, causing the spring 13444 to generate elastic force to drive the floating sprocket 1341 to tension the chain. Each guide shaft 13445 is connected to the linear bearing 13443 at one end and fixed to the fixed seat 13441 at the other end, allowing the floating power source and the floating sprocket to float along the direction of the linear bearing 13443. Since the sprocket chain will have a polygonal effect when it is running (the outline of the chain wrapped around the sprocket is not circular but polygonal), the polygonal outline will cause a certain impact force when the chain and the sprocket are engaged. Under the action of the elastic component 1344 of the present invention, the floating sprocket can be allowed to float in the direction of the linear bearing while maintaining the tension. The spring 13444 can absorb part of the impact force generated by the floating sprocket 1341 and the chain during rotation, thereby weakening the polygonal effect of the sprocket chain system during operation, and thereby reducing the overall vibration and noise of the equipment.

[0063] In one embodiment of the present invention, the linear bearing 13443 can be replaced by a linear motion component or mechanism such as a linear guide rail, a ball spline, or a bushing assembly.

[0064] FIG10 shows a schematic structural diagram of a modular vehicle 135 according to an embodiment of the present invention. The modular vehicle 135 comprises a distribution vehicle 1351 , a vertical motion module 1352 , and universal wheels 1353 .

[0065] In one embodiment of the present invention, the module vehicle 135 includes a broadcasting vehicle 1351 and a vertical movement module 1352. The broadcasting vehicle 1351 can obtain goods from the upper packaging platform 110 and deliver the goods to the material box corresponding to the goods; the vertical movement module 1352 is connected to the chain and can perform horizontal rotational movement under the drive of the chain, thereby driving the broadcasting vehicle 1351 to perform horizontal rotational movement. The vertical movement module 1352 can also drive the broadcasting vehicle 1351 to perform vertical movement.

[0066] In one embodiment of the present invention, the rotary seeding system 130 further includes a track, which is fixedly connected to the fixed drive section 131, the intermediate section 132, the intermediate drive section 133, and the floating drive section 134. A universal wheel 1353 is fixed below the vertical motion module 1352. Driven by a chain, the vertical motion module 1352 can rotate horizontally along the track using the universal wheel 1353. The track is a standard track that serves only as a guide. The vertical motion module 1352 can achieve horizontal motion using only a single universal wheel, resulting in a simple structure and low cost.

[0067] It should be pointed out that the vertical motion module 1352 here can be implemented as a linear motion module in the prior art. The linear motion module is a mature component product that drives the actuator to achieve linear reciprocating motion by means of a motor-driven screw rod or a synchronous belt plus a synchronous pulley. Other modules that can achieve linear reciprocating motion can also be used to replace the vertical motion module 1352 in the present invention, and the present invention does not impose any restrictions on this.

[0068] In one embodiment of the present invention, the seeding vehicle 1351 may be a belt roller or a flap structure. Both the belt roller and the flap structure are commonly used existing structures and will not be described in detail in the present invention.

[0069] FIG. 11 shows a schematic structural diagram of an end frame 160 according to an embodiment of the present invention.

[0070] In one embodiment of the present invention, the end frame includes an abnormality slot and a first vision camera (not shown). The abnormality slot is capable of receiving cargo with abnormal cargo information identified by the supply platform 110. The first vision camera is capable of verifying cargo information on the modular vehicle 135. The first vision camera can be implemented as a grayscale camera or other cameras or sensors with recognition capabilities, and the present invention is not limited thereto.

[0071] In one embodiment of the present invention, the end frame 160 is formed by splicing a steel frame structure and a sheet metal plate. The end frame 160 is placed at both ends of the rotating broadcasting mechanism 130, and can cover the fixed drive section 131 and the floating drive section 134 of the rotating broadcasting mechanism 120, thereby ensuring the safety of personnel and making the overall equipment beautiful.

As shown in FIG12 , the packaging platform 110 includes an electric control cabinet 111 , a packaging platform 112 , a scanning terminal 113 , and a display screen 114 .

[0073] In one embodiment of the present invention, an electrical control cabinet 111 controls the power supply of the entire goods distribution system 100. A loading platform 111 is used to place goods, and a scanning terminal 113 scans the goods to identify their information. A display screen 114 displays the operating status of the goods distribution system. Furthermore, various switches and control buttons of the goods distribution system 100 can also be integrated into the loading platform 110.

[0074] In one embodiment of the present invention, bagging can be implemented manually or automatically. Manual bagging involves a worker manually placing the goods on the bagging platform 111. The platform 110 scans the goods' information, and the worker then manually places the goods on the mobile cart 123, completing the bagging process. Automatic bagging involves replacing the platform 110 with an automatic bagging machine. After placing the goods on the machine, the machine automatically scans the goods and delivers them to the mobile cart 123.

As shown in Figures 13 and 14, the upper package window 120 includes a window baffle 121 and a strip light curtain 122.

[0076] In one embodiment of the present invention, a plurality of window baffles 121 are assembled into an area as shown in FIG. 13 or FIG. 14 , leaving a window, and the bottom of the upper window 120 is supported by feet.

[0077] In one embodiment of the present invention, the bag loading window 120 includes a strip light curtain 122 and a second visual camera (not shown in the figure). The strip light curtain 122 is a through-beam sensor, which is arranged in parallel at the window left by the window baffle 161. One is responsible for transmitting and receiving signals, and the other is responsible for reflecting signals. When the bag loading person reaches out to load the bag, the strip light curtain 122 will determine that someone is loading the bag, and will transmit the signal to the control unit. The control unit controls that no module car 135 appears at the height of the person's hand to avoid accidental injury to the person. The second visual camera can identify whether the passing module car 135 is empty and transmit the information to the control unit. The second visual camera can be implemented as a grayscale camera, or other cameras or sensors with recognition functions, and the present invention is not limited to this.
