Abstract

This invention discloses a cargo sorting system, relating to the field of cargo sorting technology. The system includes: at least one loading platform, multiple sets of material carts, a rotary sorting mechanism, multiple Cartesian coordinate sorting mechanisms, and a control unit. After a moving cart in the rotary sorting mechanism picks up cargo from the loading platform, it transports the cargo along a track to the corresponding Cartesian coordinate sorting mechanism under the control of the control unit. The Cartesian coordinate sorting mechanism receives the cargo and transports it to a matching material box. Thus, according to the technical solution of this invention, by dividing the sorting mechanism of the cargo sorting system into a rotary sorting mechanism and a Cartesian coordinate sorting mechanism, and arranging multiple sets of material carts on both sides of the lateral movement module of the corresponding Cartesian coordinate sorting mechanism, the space utilization of the sorting area and the sorting efficiency of the cargo are improved without adding additional sorting equipment, while reducing sorting costs.

[0002] Currently, with the rapid development of e-commerce and increasingly fierce competition in the e-commerce market, automated equipment is becoming increasingly important in the e-commerce field. Sorting is a crucial step in order picking in e-commerce. To improve the sorting efficiency of order goods and simplify the picking operation, intelligent sorting equipment that can automatically sort goods is gradually being applied.

[0003] Existing sorting equipment, such as linear cross-belt sorters, circular cross-belt sorters, and AGV flip-over trolleys, has a simple structure and inflexible layout. It can only extend horizontally by extending the track, but the vertical space and the space perpendicular to the track cannot be fully utilized, resulting in low sorting efficiency and low space utilization. To increase the vertical space utilization, the only way is to add more equipment, which will undoubtedly increase the cost many times over.

[0044] In one embodiment of the present invention, the track 125 is a rotary track with semi-circular ends and a straight middle section, connected end to end.

[0045] Figure 3 A schematic diagram of the structure of a drive component 121 according to an embodiment of the present invention is shown. Figure 3 As shown, the drive assembly 121 includes: a drive section welding frame 1211, an oil receiving groove 1212, a drive sprocket 1213, and a motor assembly 1214. The rotary distribution system 120 also includes: a chain guide groove 128 and a foot cup 129.

[0047] In one embodiment of the present invention, the oil receiving groove 1212 is fixedly connected to the drive assembly 121, the intermediate assembly 122, and the tensioning assembly 124, respectively, and is capable of catching and accommodating lubricating oil dripping from the chain 126. The foot cup 129 can provide overall support for the drive assembly 121 and the tensioning assembly 124.

[0048] In one embodiment of the present invention, the chain guide groove 128 is fixedly connected to the drive assembly 121, the intermediate assembly 122 and the tensioning assembly 124 respectively, and is capable of supporting the chain 126, which slides in the chain guide groove 128.

[0049] Figure 4 A schematic diagram of the structure of an intermediate component 122 according to an embodiment of the present invention is shown. Figure 4As shown, the intermediate component 122 includes: an intermediate section welding frame 1221, a sealing plate 1222, and a connector 1223. The rotating distribution system 120 also includes a base 1210.

[0050] In one embodiment of the present invention, the intermediate component 122 includes an intermediate welding frame 1221 and a plurality of connectors 1223. The intermediate welding frame 1221 is fixedly connected to the sliding contact line assembly 127 and provides support. The plurality of connectors 1223 are fixed on the intermediate welding frame 1221, and each connector 1223 is connected to a rectangular coordinate distribution mechanism 150. The rectangular coordinate distribution mechanism is connected to the rotary distribution mechanism 120 through the connectors 1223. The foot 1210 provides overall support for the intermediate component 122. The sealing plate 1222 is fixed to the middle surface of the intermediate welding frame 1221, which can enclose the middle part of the intermediate welding frame 1221, ensuring the safety of the staff and making the overall equipment aesthetically pleasing.

[0051] Figure 5 A schematic diagram of the structure of a tensioning assembly 124 according to an embodiment of the present invention is shown. Figure 5 As shown, the tensioning assembly 124 includes: a tensioning member welding frame 1241, a tensioning sprocket assembly 1242, and an elastic component 1243.

[0052] In one embodiment of the present invention, the tensioning assembly 124 includes a tensioning section welding frame 1241 and a tensioning sprocket assembly 1242. The tensioning section welding frame 1241 is fixedly connected to the sliding contact line assembly 127 and provides support. The tensioning sprocket assembly 1242 includes a tensioning sprocket and a sprocket accessory connected to the tensioning sprocket. The sprocket accessory is fixed on the tensioning section welding frame 1241. The tensioning sprocket is connected to the chain 126 and can tension the chain 126.

[0053] Figure 6 A schematic diagram of the structure of an elastic component 1243 according to an embodiment of the present invention is shown. Figure 6 As shown, the elastic component 1243 includes a fixed base 12431, a long screw 12432 with a nut, a guide shaft 12433, a spring 12434, and a linear bearing 12435.

[0054] In one embodiment of the present invention, the tensioning assembly 124 further includes an elastic assembly 1243, which includes a fixed base 12431, a spring 12434, a long screw 12432 with a nut, a plurality of guide shafts 12433 and a linear bearing 12435. The fixed seat 12431 is fixed on the tensioning section welding frame 1241; the long screw 12432 with a nut is fixed on the fixed seat 12431; the spring 12434 is sleeved on the long screw 12432 with a nut, and one end of the spring 12434 abuts against the sprocket accessory, and the other end abuts against the nut. By rotating the nut to compress the spring 12434, the spring 12434 can generate elastic force to drive the tensioning sprocket to tension the chain 126; one end of each guide shaft 12433 is connected to the linear bearing 12435, and the other end is connected to the fixed seat 12431. The linear bearing 12435 is fixed on the fixed seat 12431 and fixedly connected to the sprocket accessory, which allows the tensioning sprocket to float along the direction of the linear bearing 12435. Because the sprocket and chain exhibit a polygonal effect during operation (the outline of the chain enveloping the sprocket is not circular but polygonal), this polygonal outline causes a certain impact force when the chain and sprocket mesh. Under the action of the tensioning component 124 of this invention, the tensioning sprocket is allowed to float in the direction of the linear bearing while maintaining the tension force. The spring 12434 can absorb part of the impact force generated when the tensioning sprocket and chain 126 rotate, thereby weakening the polygonal effect of the sprocket and chain system during operation, and thus reducing the overall vibration and noise of the equipment.

[0055] In one embodiment of the present invention, the linear bearing 12435 can be replaced by linear motion components or mechanisms such as linear guide rails, ball splines, and bushing assemblies.

[0056] Figure 7 A schematic diagram of the structure of a mobile vehicle 123 according to an embodiment of the present invention is shown. Figure 7 As shown, the mobile vehicle 123 includes a vehicle body 1231, a cargo platform 1232, and casters 1233.

[0057] In one embodiment of the present invention, a plurality of mobile vehicles 123 are evenly distributed along the direction of track 125.

[0058] In one embodiment of the present invention, the mobile vehicle 123 includes a vehicle body 1231, multiple loading platforms 1232, and casters 1233. The vehicle body 1231 is fixedly connected to a chain 126; the multiple loading platforms 1232 are fixed on the vehicle body 1231 and can pick up goods from the upper packaging platform 110 and throw the goods to the rectangular coordinate sorting mechanism 150 where the matching material box is located; the casters 1233 are fixed on the vehicle body 1231 and connected to a track 125, and can roll along the track 125. The vehicle body can be made of sheet metal welded frame, which serves as the overall support for the mobile vehicle 123. The vertical positions of the multiple loading platforms 1232 are fixed and cannot move up or down relative to the vehicle body 1231. A mobile vehicle 123 is equipped with multiple loading platforms 1232, which can pick up multiple goods from the upper packaging platform at the same time and transport multiple goods at the same time, improving sorting efficiency. The loading platform here can be implemented as a belt roller mechanism or a flip-plate structure. Both belt roller mechanisms and flip-plate structures are commonly used existing structures, and will not be described in detail in this invention.

[0059] It should be noted that the number of loading platforms 1232 on the mobile vehicle 123 can be set as needed. Figure 7 The loading platform 1232 in the diagram is only provided as an example.

[0060] Figure 8 A schematic diagram of the assembly structure of the mobile vehicle 123 and the chain 126 according to an embodiment of the present invention is shown. Figure 9 A side view of the assembly structure of the mobile vehicle 123 and the chain 126 according to an embodiment of the present invention is shown. Figure 8 and Figure 9 The mobile vehicle 123 shown is connected to the chain 126 by a pin structure, which includes a cotter pin 1234, a cylindrical pin 1235, and a bracket 1236.

[0061] In one embodiment of the present invention, the bracket 1236 is fixedly connected to the chain 126, and the body 1231 of the moving vehicle 123 is fixedly connected to the cylindrical pin 1235. The cylindrical pin 1235 and the bracket 1236 are connected by a cotter pin 1234, thereby achieving a fixed connection between the moving vehicle 123 and the chain 126. Through this pin-structure connection, the cylindrical pin 1235 can rotate relative to the bracket 1236. This allows the moving vehicle 123 to adapt well to uneven sections of the track or the presence of small foreign objects on the track, preventing collisions and excessive noise.

[0062] Figure 10 This diagram shows a three-dimensional assembly structure of a Cartesian coordinate distribution mechanism 150 and a material box cart 140 according to an embodiment of the present invention. Figure 11 A schematic diagram of the assembly side structure of the Cartesian coordinate distribution mechanism 150 and the material box trolley 140 according to an embodiment of the present invention is shown. Figure 10and Figure 11 As shown, the rectangular coordinate distribution mechanism 150 includes: a support frame 151, a horizontal motion module 152, a chute 153, a distribution vehicle 154, and a vertical motion module 155. The material box vehicle 140 includes: a material box 141 and a material box frame 142.

[0063] In one embodiment of the present invention, the Cartesian coordinate distribution system 150 includes a support frame 151, a distribution vehicle 154, multiple chutes 153, a vertical motion module 155, and a horizontal motion module 152. The chutes 153 are fixed to the support frame 151, and the number of chutes is the same as the number of loading platforms 1232 on the mobile vehicle 123. The loading platforms 1232 on the mobile vehicle 123 deliver goods to the chutes 153, and the goods slide through the chutes to the distribution vehicle 154, where they are delivered to the corresponding bins. The distribution vehicle 154 is connected to the vertical motion module 155, which drives the distribution vehicle 154 to perform vertical movement. When goods need to be received, the vertical motion module 155 controls the distribution vehicle 154 to move to the height of the chutes 153 corresponding to the goods, so that the distribution vehicle 154 can receive goods from the chutes. The chute 153 picks up goods, and then during the distribution of goods, the vertical motion module 155 drives the distribution vehicle 154 to move to the height of the material box 141 so that the distribution vehicle 154 can deliver the goods to the corresponding material box 141. The extension direction of the horizontal motion module 152 is perpendicular to the extension direction of the track 125 on the middle component 122 of the rotating distribution mechanism 120. The horizontal motion module 152 is connected to the vertical motion module 155 and can drive the vertical motion module 155 to perform reciprocating linear motion along the extension direction of the horizontal motion module 152, thereby driving the distribution vehicle 154 to perform reciprocating linear motion through the vertical motion module 155. In this way, by cooperating with the rectangular coordinate sorting mechanism 150 and the rotary sorting mechanism 120, the sorting process of goods is transformed from a combination of horizontal rotation and vertical motion to a combination of horizontal rotation followed by longitudinal motion ("longitudinal" means the horizontal direction perpendicular to the straight section of the track) and vertical motion. Without adding a new goods sorting system 100, the distribution of the bins can be extended longitudinally, thereby improving space utilization. Only one goods sorting system 100 is needed to achieve large-area goods sorting, saving costs and improving sorting efficiency.

[0064] The distribution vehicle here can be implemented as a belt roller mechanism or a flip-plate structure. Both belt roller mechanisms and flip-plate structures are commonly used existing structures, and will not be described in detail in this invention.

[0065] It should be noted that both the horizontal motion module 152 and the vertical motion module 155 here can be implemented as linear motion modules in the prior art. A linear motion module is a mature component product that drives the actuator to achieve linear reciprocating motion by means of a motor driving a lead screw or driving a synchronous belt and a synchronous pulley. Other modules that can achieve linear reciprocating motion can also be used to replace the horizontal motion module 152 or the vertical motion module 155 in this invention, and this invention does not limit them.

[0066] In one embodiment of the present invention, each set of hopper carts 140 is arranged on both sides of the lateral movement module 152 of the corresponding Cartesian coordinate distribution mechanism 150. The length of the hopper cart 140 corresponds to the length of the Cartesian coordinate distribution mechanism 150, and the hoppers 141 are arranged in multiple rows and columns on the hopper frame 142. The arrangement of multiple sets of hopper carts 140 on both sides of the lateral movement module 152 of the corresponding Cartesian coordinate distribution mechanism 150 greatly increases the number of hoppers that can be configured in the cargo distribution system 100, thereby improving space utilization.

[0067] Figure 12 A schematic diagram of the structure of an end frame 130 according to an embodiment of the present invention is shown.

[0068] In one embodiment of the present invention, the end frame 130 is formed by splicing steel frame structure and sheet metal plate together. The end frame 130 is placed at both ends of the rotating distribution mechanism 120 and can cover the drive component 121 and tension component 124 of the rotating distribution mechanism 120, thereby ensuring personnel safety and making the overall equipment aesthetically pleasing.

[0069] Figure 13 A schematic diagram of the structure of an upper packaging platform 110 according to an embodiment of the present invention is shown. Figure 13 As shown, the loading platform 110 includes: an electrical control cabinet 111, a loading platform 112, a sweeping dock 113, and a display screen 114.

[0070] In one embodiment of the present invention, the electrical control cabinet 111 can control the power control of the entire cargo distribution system 100, the loading platform 111 is suitable for placing goods, and the scanning dock 113 scans the goods to identify the goods information, and the display screen 114 is suitable for displaying the operation status of the cargo distribution system. In addition, various switches and control buttons of the cargo distribution system 100 can also be integrated and installed in the loading platform 110.

[0071] In one embodiment of the present invention, the loading process can be either manual or automatic. The manual loading process involves: a worker manually placing the goods on the loading platform 111; the loading platform 110 scanning the goods' information; and then the worker manually placing the goods onto the mobile cart 123 to complete the loading process. The automatic loading process involves replacing the loading platform 110 with an automatic loading machine; after the goods are placed on the automatic loading machine, the machine automatically scans the goods and delivers them to the mobile cart 123.

[0072] Figure 14 A schematic diagram of the structure of the upper window 160 according to an embodiment of the present invention is shown. Figure 14 As shown, the upper window 160 includes a window baffle 161 and a strip light curtain 162.

[0073] In one embodiment of the present invention, a plurality of window baffles 161 are assembled as follows: Figure 14 The area shown has a window, and the bottom of the upper window 160 is supported by feet.

[0074] In one embodiment of the present invention, the bag-loading window 160 includes a strip light curtain 162 and a grayscale camera (not shown in the figure). The strip light curtain 162 is a through-beam sensor, arranged parallel to the window provided by the window baffle 161. One sensor is responsible for transmitting and receiving signals, and the other is responsible for reflecting signals. When a person reaches for the bag, the strip light curtain 162 determines that a person is loading the bag and transmits the signal to the control unit. The control unit prevents any moving cart 123 from appearing at the height of the person's hand to avoid accidental injury. The grayscale camera can identify whether the passing moving cart 123 is empty and transmits this information to the control unit.

[0075] In summary, according to the technical solution of the present invention, a cargo sorting scheme is provided. The cargo sorting system achieves cargo sorting and includes at least one loading platform, multiple sets of material carts, a rotary sorting mechanism, multiple Cartesian coordinate sorting mechanisms, and a control unit. Multiple Cartesian coordinate sorting mechanisms are distributed on both sides of the rotary sorting mechanism, each Cartesian coordinate sorting mechanism corresponding to one set of material carts. The multiple sets of material carts are respectively arranged on both sides of the lateral movement module of the corresponding Cartesian coordinate sorting mechanism. After the moving cart in the rotary sorting mechanism picks up the cargo from the loading platform, under the control of the control unit, it transports the cargo along the track to the corresponding Cartesian coordinate sorting mechanism. The Cartesian coordinate mechanism receives the cargo and transports it to the matching material box. The tensioning component of the rotary sorting system, based on the existing tensioning sprocket, adds an elastic component consisting of a fixed seat, spring, long nut, guide shaft, and linear bearing. Thus, according to the technical solution of the present invention, by dividing the sorting mechanism of the cargo sorting system into a rotary sorting mechanism and a rectangular coordinate sorting mechanism, the rotary sorting mechanism first realizes the lateral sorting of goods, and then the rectangular coordinate sorting mechanism realizes the longitudinal and vertical sorting of goods. Multiple sets of material carts are respectively arranged on both sides of the lateral motion module of the corresponding rectangular coordinate sorting mechanism, thereby expanding the number of material carts in the longitudinal direction, greatly increasing the number of material carts that can be configured in the cargo sorting system. Without adding additional sorting equipment, the space utilization rate of the sorting site and the sorting efficiency of goods are improved, and the sorting cost is reduced. The newly added elastic tensioning component allows the tensioning sprocket to float in the direction of the linear bearing while maintaining the tension force. The spring can absorb part of the impact force generated when the tensioning sprocket and chain rotate, thereby weakening the polygonal effect of the sprocket and chain system during operation, and thus reducing the overall vibration and noise of the equipment.

[0076] Furthermore, embodiments of the present invention also include: A11, a cargo sorting system as described in any one of A1-10, wherein each group of the material box carts is arranged on both sides of the lateral motion module of the corresponding rectangular coordinate sorting mechanism. A12, a cargo sorting system as described in any one of A1-11, wherein the track is a rotary track with semi-circular ends and a straight middle section, connected end to end; the plurality of moving carts are evenly distributed along the direction of the track. A13, a cargo sorting system as described in any one of A1-12, wherein the system further includes: end frames, placed at both ends of the rotating sorting mechanism to shield the rotating sorting mechanism. A14, a cargo sorting system as described in A7, wherein the sorting cart is a belt roller or a flip-plate structure. A15, a cargo sorting system as described in any one of A1-14, wherein the system further includes a loading window, the loading window including: a strip light curtain, adapted to detect whether personnel are performing loading actions; a grayscale camera, adapted to identify whether the moving cart is empty.
