Description

[0051] In one embodiment of the present invention, the intermediate component 122 includes an intermediate section welding frame 1221 and a plurality of connectors 1223.

[0052] FIG5 is a schematic structural diagram of a tensioning assembly 124 according to an embodiment of the present invention. As shown in FIG5 , the tensioning assembly 124 comprises: a tensioning member welding frame 1241 , a tensioning sprocket assembly 1242 , and an elastic assembly 1243 .

[0053] 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 busbar assembly 127 and provides support.

The sprocket assembly is fixed to the tensioning section welding frame 1241. The tensioning sprocket is connected to the chain 126 and can tension the chain 126.

[0054] FIG6 shows a schematic structural diagram of an elastic component 1243 according to an embodiment of the present invention. As shown in FIG6 , the elastic component 1243 includes a fixing seat 12431 , a long screw rod 12432 with a nut, a guide shaft 12433 , a spring 12434 , and a linear bearing 12435 .

[0055] In one embodiment of the present invention, the tensioning assembly 124 further includes an elastic assembly 1243 , which includes a fixing seat 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 rod 12432 with a nut is fixed on the fixed seat 12431; the spring 12434 is sleeved on the long screw rod 12432 with a nut, and one end of the spring 12434 is in contact with the sprocket accessory, and the other end is in contact with 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 12431. The linear bearing 12435 is fixed on the fixed seat 12431 and fixedly connected to the sprocket accessory, so that the tensioning sprocket can float along the direction of the linear bearing 12435. 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 tensioning component 124 of the present invention, while maintaining the tensioning force, the tensioning sprocket can be allowed to float in the direction of the linear bearing. The spring 12434 can absorb part of the impact force generated by the tensioning sprocket and chain 126 when they rotate, thereby weakening the polygonal effect of the sprocket chain system during operation, and thereby reducing the overall vibration and noise of the equipment.

[0056] In one embodiment of the present invention, the linear bearing 12435 can be replaced by a linear motion component or mechanism such as a linear guide rail, a ball spline, or a bushing assembly.

[0059] In one embodiment of the present invention, the mobile vehicle 123 includes a vehicle body 1231, multiple cargo platforms 1232, and universal wheels 1233. The vehicle body 1231 is fixedly connected to the chain 126; multiple cargo platforms 1232 are fixed on the vehicle body 1231, and can obtain goods from the upper packaging platform 110 and throw the goods to the rectangular coordinate distribution mechanism 150 where the material box matching the goods is located; the universal wheels 1233 are fixed on the vehicle body 1231, connected to the track 125, and can roll along the track 125. The vehicle body can be made of a sheet metal welded frame, which plays a supporting role for the mobile vehicle 123 as a whole. The positions of the multiple cargo platforms 1232 in the vertical direction are fixed and cannot move up and down relative to the vehicle body 1231. A mobile vehicle 123 is provided with multiple cargo platforms 1232, which can obtain multiple goods at the upper packaging platform at the same time and transport multiple goods at the same time, thereby improving sorting efficiency. The cargo platform here can be realized as a belt roller mechanism or a flap structure. The belt roller mechanism and the flap structure are both commonly used existing structures, and the present invention will not elaborate on them.

[0060] It should be noted that the number of cargo platforms 1232 on the mobile vehicle 123 can be set as needed, and the cargo platforms 1232 in FIG. 7 are only for illustrative purposes.

[0061] Figure 8 shows a schematic diagram of the assembly structure of the mobile vehicle 123 and the chain 126 according to one embodiment of the present invention, and Figure 9 shows a side schematic diagram of the assembly structure of the mobile vehicle 123 and the chain 126 according to one embodiment of the present invention. As shown in Figures 8 and 9, the mobile vehicle 123 and the chain 126 are connected by a pin structure, which includes a cotter pin 1234, a cylindrical pin 1235, and a bracket 1236.

[0062] In one embodiment of the present invention, bracket 1236 is fixedly connected to chain 126, and body 1231 of mobile vehicle 123 is fixedly connected to cylindrical pin 1235. Cylindrical pin 1235 and bracket 1236 are connected via cotter pin 1234, thereby achieving a fixed connection between mobile vehicle 123 and chain 126. This pin structure connection allows cylindrical pin 1235 to rotate relative to bracket 1236. In this way, mobile vehicle 123 can adapt well to track imbalances or small foreign objects on the track without causing collisions and generating loud noise.

[0063] Figure 10 shows a schematic diagram of the assembled three-dimensional structure of a rectangular coordinate seeding mechanism 150 and a container cart 140 according to one embodiment of the present invention. Figure 11 shows a schematic diagram of the assembled side structure of the rectangular coordinate seeding mechanism 150 and the container cart 140 according to one embodiment of the present invention. As shown in Figures 10 and 11, the rectangular coordinate seeding mechanism 150 includes a carrier frame 151, a lateral motion module 152, a chute 153, a seeding cart 154, and a vertical motion module 155. The container cart 140 includes a container 141 and a container frame 142.

[0064] In one embodiment of the present invention, the rectangular coordinate broadcasting system 150 includes a carrier 151, a broadcasting vehicle 154, a plurality of chutes 153, a vertical motion module 155, and a horizontal motion module 152. The chutes 153 are fixed on the carrier 151, and the number of chutes is the same as the number of cargo platforms 1232 on the mobile vehicle 123. The cargo platforms 1232 on the mobile vehicle 123 deliver the goods to the chutes 153, and the goods slide to the broadcasting vehicle 154 through the chutes, and the broadcasting vehicle 154 delivers the goods to the material box corresponding to the goods; the broadcasting vehicle 154 is connected to the vertical motion module 155, and the vertical motion module 155 can drive the broadcasting vehicle 154 to move vertically. When there is goods to be received, the vertical motion module 155 controls the broadcasting vehicle 154 to move to the height of the chute 153 corresponding to the goods. So that the sowing vehicle 154 can obtain the goods from the chute 153, and then in the process of sowing the goods, the vertical movement module 155 drives the sowing vehicle 154 to move to the height of the material box 141, so that the sowing vehicle 154 can deliver the goods to the corresponding material box 141; the extension direction of the transverse movement module 152 is perpendicular to the extension direction of the track 125 on the intermediate component 122 of the rotating sowing mechanism 120, and the transverse movement module 152 is connected to the vertical movement module 155, which can drive the vertical movement module 155 to perform reciprocating linear motion along the extension direction of the transverse movement module 152, and then drive the sowing vehicle 154 to perform reciprocating linear motion through the vertical movement module 155. In this way, through the cooperation of the rectangular coordinate distribution mechanism 150 and the rotary distribution mechanism 120, the sorting process of goods is transformed from a combination of horizontal rotational movement and vertical movement to first performing horizontal rotational movement and then performing a combination of longitudinal movement ("longitudinal" means the horizontal direction perpendicular to the straight section of the track) and vertical movement. Without adding a new goods distribution system 100, the distribution of the material boxes can be extended in the longitudinal direction, thereby improving the space utilization rate. Only one goods distribution system 100 is needed to achieve large-scale goods distribution, saving costs and improving sorting efficiency.

[0065] The seeding vehicle here can be realized as a belt roller mechanism or a flap structure. The belt roller mechanism and the flap structure are both commonly used existing structures, and the present invention will not elaborate on them.

[0066] It should be pointed out that the lateral motion module 152 and the vertical motion module 155 here can both be implemented as linear motion modules 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 lateral motion module 152 or the vertical motion module 155 in the present invention, and the present invention does not impose any restrictions on this.

[0067] In one embodiment of the present invention, each group of container carts 140 is positioned on either side of the corresponding transverse motion module 152 of the rectangular coordinate distribution mechanism 150. The length of the container carts 140 corresponds to the length of the rectangular coordinate distribution mechanism 150, and the containers 141 are arranged in multiple rows and columns on the container rack 142. This arrangement of multiple container carts 140 on either side of the corresponding transverse motion module 152 of the rectangular coordinate distribution mechanism 150 significantly increases the number of containers that can be configured in the goods distribution system 100, improving space utilization.

[0068] FIG. 12 shows a schematic structural diagram of an end frame 130 according to an embodiment of the present invention.

[0069] In one embodiment of the present invention, the end frame 130 is formed by splicing a steel frame structure and a sheet metal plate. The end frame 130 is placed at both ends of the rotary broadcasting mechanism 120, and can shield the driving component 121 and the tensioning component 124 of the rotary broadcasting mechanism 120, thereby ensuring the safety of personnel and making the overall appearance of the equipment.

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.

[0072] 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.

[0073] FIG14 shows a schematic structural diagram of an upper package window 160 according to an embodiment of the present invention. As shown in FIG14 , the upper package window 160 includes a window baffle 161 and a strip light curtain 162 .

[0074] In one embodiment of the present invention, a plurality of window baffles 161 are assembled into an area as shown in FIG. 14 , leaving a window, and the bottom of the upper window 160 is supported by feet.

[0075] 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, 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 162 will determine that someone is loading the bag and will transmit the signal to the control unit. The control unit controls the mobile vehicle 123 to prevent it from appearing at the height of the person's hand to avoid accidental injury to the person. The grayscale camera can identify whether the passing mobile vehicle 123 is empty and transmit this information to the control unit.

[0076] In summary, according to the technical solution of the present invention, a cargo distribution solution is provided. The cargo distribution system is used to sort the cargo, and the system includes at least one upper packaging platform, multiple groups of material box carts, a rotary distribution mechanism, multiple rectangular coordinate distribution mechanisms, and a control unit. Multiple rectangular coordinate distribution mechanisms are distributed on both sides of the rotary distribution mechanism, and each rectangular coordinate distribution mechanism corresponds to a group of material box carts. Multiple groups of material box carts are respectively arranged on both sides of the lateral motion module of the corresponding rectangular coordinate distribution mechanism. After the mobile vehicle in the rotary distribution mechanism obtains the cargo from the upper packaging platform, it is controlled by the control unit to transport the cargo along the track to the corresponding rectangular coordinate distribution mechanism. After receiving the cargo, the rectangular coordinate distribution mechanism transports the cargo to the material box that matches the cargo. On the basis of setting a tensioning sprocket, the tensioning component of the rotary distribution system is newly added with an elastic component consisting of a fixed seat, a spring, a long nut, a guide shaft and a linear bearing. In this way, 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 lateral sorting of the cargo is first realized by the rotary sorting mechanism, and then the longitudinal and vertical sorting of the cargo is realized by the rectangular coordinate sorting mechanism. Multiple groups of material box vehicles are respectively arranged on both sides of the lateral movement module of the corresponding rectangular coordinate sorting mechanism, thereby realizing the expansion of the number of longitudinal loading boxes, greatly increasing the number of material boxes that can be configured for the cargo sorting system, and improving the space utilization rate of the sorting site and the sorting efficiency of cargo without adding additional sorting equipment, thereby reducing the sorting cost. The newly added tensioning component of the elastic component can allow the tensioning sprocket to float in the direction of the linear bearing while maintaining the tensioning force. The spring can absorb part of the impact force generated by the tensioning sprocket and chain during rotation, thereby weakening the polygonal effect of the sprocket chain system during operation, thereby reducing the overall vibration and noise of the equipment.
