Description

Technical Field

[0001] The present invention relates to the technical field of cargo management, and in particular to a cargo circulation distribution device based on the Internet of Things. Background Art

[0002] At present, the main purpose of cargo flow distribution is to optimize logistics operation efficiency, reduce costs, improve customer satisfaction and enhance corporate competitiveness. Through reasonable cargo flow distribution, we can ensure that each link is carried out in an orderly manner, reduce human errors, ensure the safety of cargo transportation, and thus improve the smoothness of overall logistics operations.

[0003] However, in the modern logistics industry, as the number of goods handled continues to grow, the pressure on the circulation and distribution of goods has also increased accordingly. At present, most cargo distribution equipment uses a reciprocating drive mechanism to push the goods on the transmission line through external force and sort them into different conveying paths to achieve effective distribution of goods. In addition, when using a reciprocating propulsion structure for cargo distribution, the transmission speed of the goods must be accurately controlled, and even the transmission line needs to be stopped to prevent the speed from being too high and affecting the accuracy of the propulsion mechanism in distributing the goods, so as to avoid the problem of the goods deviating from the predetermined output path.

[0004] When the cargo handling volume increases sharply in a short period of time, if the cargo encounters a drop in the speed of the transmission line or stops at the sorting or distribution node, this will cause the cargo transmission speed of the entire transmission line to slow down or even stagnate. This will not only affect the overall cargo flow efficiency and reduce the efficiency of cargo flow distribution, but also cause cargo backlogs and extend the cargo flow distribution time.

[0005] Secondly, if the goods to be processed contain more distribution items, multiple distribution nodes are required to meet the circulation mode. If multiple distribution nodes divert goods at the same time, and if the transmission line of each distribution node slows down or stops when diverting goods, and then outputs the goods to the corresponding distribution line through the reciprocating mechanism, the cumulative delay time of multiple distribution nodes will increase further, affecting the speed of overall goods transmission, and will also cause a large backlog of goods, extending the overall processing cycle of goods circulation and distribution. Summary of the invention

[0006] The purpose of the present invention is to provide a cargo circulation distribution device based on the Internet of Things to solve the problems raised in the above background technology.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] See also Figures 1 to 9 , the present invention provides the following two embodiments:

[0054] Embodiment 1:

[0055] See also Figure 1 A cargo circulation distribution device based on the Internet of Things includes a distribution transmission line 100, which is used to transmit cargo and output the distributed cargo.

[0056] See also Figure 1 and Figure 2 The distribution transmission line 100 includes a second roller conveying line 120 , and the second roller conveying line 120 includes a plurality of roller members 121 .

[0057] It is worth noting that the roller component 121 is the main component of the roller conveyor line. The roller conveyor line is a mature existing technology. Personnel in the relevant technical field can clearly understand its working principle and driving principle, and will not be elaborated in this technical solution.

[0058] The distribution transmission line 100 further includes a first roller conveyor line 110 and a third roller conveyor line 130, which are respectively arranged on both sides of the second roller conveyor line 120. The upper surfaces of the first roller conveyor line 110 and the third roller conveyor line 130 are flush with the upper surface of the second roller conveyor line 120.

[0059] The second roller conveyor line 120 is used for continuously conveying goods. After passing through the second identification component 400, the goods are output from the second roller conveyor line 120 to the first roller conveyor line 110 or the third roller conveyor line 130. The first roller conveyor line 110 and the third roller conveyor line 130 are used for outputting the allocated goods, which is beneficial for the staff to centrally handle the allocated goods and facilitate the subsequent circulation of the goods.

[0060] See also Figures 1 to 3 The second roller conveyor line 120 also includes a first identification component 200, a distribution component 300 and one or more second identification components 400.

[0061] See also Figure 4 and Figure 5 , the first recognition component 200 and the second recognition component 400 both include a recognition module 500 and a measurement module 600 .

[0062] Specifically, the identification module 500 is a barcode scanner, and the barcode scanner adopts the MS-3 model of the Meji company. This model of barcode scanner is a commonly used device, suitable for automatic barcode scanning on the production line, and can be used on the assembly line, and can be used to scan the moving barcode. When applied to this technical solution, it can dynamically scan the corresponding information barcode on the surface of the goods transmitted on the second roller conveyor line 120 to obtain the information contained in the barcode of the goods.

[0063] Specifically, the measuring module 600 is a grating ruler, and the grating ruler adopts the Heidenhain GBC2-B10 model, which is a standard grating ruler. The working principle of the grating ruler is based on the physical principle of Moire fringe formation. When the indicator grating and the scale grating are placed at a certain angle, light and dark stripes will be produced under the illumination of the light source. The movement of these stripes can accurately reflect the displacement change of the object. The grating ruler can measure the length or displacement of the object by reading the changes in these stripes. When applied to this solution, the grating ruler is used to measure the length of the goods in transit, so as to be used for the subsequent determination of the number of smooth strips 311 required to lift the goods.

[0064] It is worth noting that the specific model devices used in the above-mentioned identification module 500 and measurement module 600 are mature existing technologies. Those skilled in the art can find the instructions for use and specific usage principles of the relevant equipment according to the model, and will not be elaborated in this technical solution.

[0065] See also Figure 3 and Figure 4 The first identification component 200 also includes a first processor 210, the second identification component 400 also includes a second processor 410 and an Internet of Things terminal 220, and communication channels are established between the Internet of Things terminal 220 and the identification module 500, the measurement module 600, the first processor 210 and the second processor 410, and a communication channel is established between the Internet of Things terminal 220 and the control terminal of the distribution transmission line 100.

[0066] It is worth noting that the communication channel uses the IoT channel, which is a dedicated channel for the Internet of Things and is used to connect IoT devices and transmit data and commands.

[0067] The first processor 210 is used to collect the barcode information and cargo length information respectively collected by the identification module 500 and the measurement module 600 in the first identification component 200, and the second processor 410 is used to collect the barcode information and cargo length information respectively collected by the identification module 500 and the measurement module 600 in the second identification component 400, and upload them to the Internet of Things terminal 220 through the communication channel. At the same time, the Internet of Things terminal 220 can also transmit data and commands in reverse to the first processor 210 and the second processor 410.

[0068] See also Figure 1 and Figure 2 The distribution assembly 300 includes a plurality of lifting assemblies 310 and a driving controller 320 . The distribution assembly 300 includes a smooth bar 311 , a sub-controller 312 , a first electric push rod 314 and a second electric push rod 315 . The smooth bar 311 is disposed between the roller components 121 .

[0069] See also Figures 6 to 9 The upper ends of the first electric push rod 314 and the second electric push rod 315 are rotatably installed inside the two ends of the smooth bar 311, and a communication channel is established between the driving controller 320 and the multiple sub-controllers 312 and the Internet of Things terminal 220.

[0070] It is worth noting that the first electric push rod 314 is located at one end of the smooth bar 311 close to the third roller conveyor line 130, and the second electric push rod 315 is located at one end of the smooth bar 311 close to the first roller conveyor line 110. The purpose of the above-mentioned setting method is that when the goods need to be distributed to the first roller conveyor line 110, the first electric push rod 314 is pushed out to tilt the smooth bar 311 toward the first roller conveyor line 110, so that the goods on the smooth bar 311 slide toward the first roller conveyor line 110. Conversely, when the goods need to be distributed to the third roller conveyor line 130, the second electric push rod 315 is pushed out to tilt the smooth bar 311 toward the third roller conveyor line 130, so that the goods on the smooth bar 311 slide toward the third roller conveyor line 130.

[0071] The first electric push rod 314 and the second electric push rod 315 are both servo electric push rods. The first electric push rod 314 and the second electric push rod 315 both include a servo driver 313 , and the servo driver 313 is electrically connected to the sub-controller 312 .

[0072] It is worth noting that the servo electric push rod is a mature existing technology. People in the relevant field can understand its specific working principle and installation method based on conventional mechanical knowledge. Secondly, the selected model of the servo electric push rod can be adaptively selected according to the cargo weight range. The servo driver 313 matched with the servo electric push rod is used to control the servo motor in the servo electric push rod. It is also a mature existing technology. People in the relevant field can adaptably select it based on mechanical knowledge. In summary, the servo electric Tiguan and the servo driver 313 are both conventional and mature existing technologies. When applied to this solution, people in this field can look up the instructions for use and specific principles of use of the relevant equipment according to the model, and will not be elaborated in this technical solution.

[0073] Specifically, in the actual goods circulation distribution process, when the first roller conveyor line 110 and the third roller conveyor line 130 are respectively arranged on both sides of the second roller conveyor line 120, the distribution method includes the following steps:

[0074] S1: The staff installs multiple second identification components 400 on the surface of the second roller conveyor line 120, and connects the second processor 410 to the Internet of Things terminal 220 for communication. Secondly, the second processor 410 can set the output directions of the first roller conveyor line 110 and the third roller conveyor line 130 on both sides of the second identification component 400 to two different distribution nodes through the Internet of Things terminal 220, that is, the two sides of the same second identification component 400 are different flow distribution paths.

[0075] Then the staff will sequentially input the goods to be circulated and distributed onto the second roller conveyor line 120, and set the transmission speed of the second roller conveyor line 120 in advance, so that the goods are transmitted on the surface of the second roller conveyor line 120. After the goods pass through the first recognition component 200, the recognition module 500 and the measurement module 600 in the first recognition component 200 respectively recognize the barcode and size of the goods, and upload the barcode and size information to the first processor 210.

[0076] S2: The barcode information and size information of the goods on the first processor 210 are uploaded to the Internet of Things terminal 220 .

[0077] S3: The IoT terminal 220 classifies the barcode information and size information of the goods, and stores the estimated size information of the goods barcode. The IoT terminal 220 matches the allocation information items stored in the second processor 410, that is, the staff sends the corresponding information of the allocation items to the second processor 410 through the IoT terminal 220, so that the second identification component 400 can identify the goods information.

[0078] S4: After the goods pass through the first identification component 200, they are transmitted along the surface of the second roller conveyor line 120, and the goods pass through the second identification component 400 in turn. The identification module 500 of the second identification component 400 reads the barcode of the goods in turn. After the barcode of the goods matches the goods distribution information stored in the second processor 410, the distribution component 300 is controlled to push out multiple flow strips 311.

[0079] The control method of fluent bar 311 is as follows:

[0080] S41: The IoT terminal 220 sequentially numbers the multiple lifting components 310 along the direction of cargo input, and directly schedules the lifting components 310 with corresponding numbers in subsequent scheduling. The IoT terminal 220 calculates the time difference between the first identification component 200 and the second identification component 400 in identifying the cargo barcode, and obtains the current position of the second identification component 400 on the second roller conveyor line 120 based on the transmission speed of the second roller conveyor line 120.

[0081] S42: The IoT terminal 220 calculates the number of required lifting components 310 according to the cargo size measured by the measuring module 600.

[0082] S43: When the goods pass through the second identification component 400, after the identification module 500 matches the barcode of the goods, the second processor 410 determines the ejection tilt direction of the smooth bar 311, and the Internet of Things terminal 220 issues a lifting instruction to the drive controller 320.

[0083] S44: The driving controller 320 controls the first electric push rod 314 and the second electric push rod 315 in the jacking assembly 310 with the corresponding number to generate jacking according to the position of the second identification assembly 400 and the number of the jacking assemblies 310 issued by the Internet of Things terminal 220.

[0084] S45: The driving controller 320 controls the time of the entire process of ejection and retraction of the first electric push rod 314 and the second electric push rod 315 according to the conveying speed of the second roller conveyor line 120. After the goods slide out of the second roller conveyor line 120, the smooth bar 311 in the lifting assembly 310 is reset. Figure 8 , the smooth strip 311 is ejected toward the third roller conveyor line 130, see Fig. 9 , see the reset status of fluent bar 311 Figure 7 .

[0085] After the second identification component 400 identifies the barcode of the goods, the lifting component 310 on one side of the second identification component 400 is ejected in sequence according to the transmission direction of the second roller conveyor line 120, and the smooth strip 311 is ejected and oriented in the direction of the corresponding distribution path. In this process, the maintenance time of the lifting component 310 that ejects the smooth strip 311 to the highest point is: the time for the lifting component 310 to maintain the fully ejected state is obtained by dividing the size of the goods by the transmission speed of the second roller conveyor line 120. The drive controller 320 controls the number of fully ejected lifting components 310 to be close to the length of the goods, and its function is to keep multiple smooth strips 311 in contact with the bottom surface of the goods at the same time, so that the goods can stably slide to the first roller conveyor line 110 or the third roller conveyor line 130 through the pulley on the surface of the smooth strip 311.

[0086] S5: After the smooth strip 311 at the bottom of the goods is pushed out, the goods slide out of the surface of the second roller conveyor line 120 along the surface of the smooth strip 311 and enter the surface of the first roller conveyor line 110 or the third roller conveyor line 130 respectively.

[0087] Embodiment 2:

[0088] Based on the above technical solution, another embodiment is proposed again:

[0089] When only the first roller conveyor line 110 or only the third roller conveyor line 130 is provided on one side of the second roller conveyor line 120 .

[0090] The goods circulation allocation method is as follows:

[0091] S1: The staff installs multiple second identification components 400 on the surface of the second roller conveyor line 120, and connects the second processor 410 to the Internet of Things terminal 220 for communication. Secondly, the second processor 410 can set the output direction of the first roller conveyor line 110 or the third roller conveyor line 130 on both sides of the second identification component 400 as a distribution node through the Internet of Things terminal 220, that is, the second identification component 400 can only distribute the goods to the first roller conveyor line 110 or the third roller conveyor line 130.

[0092] Then the staff will sequentially input the goods to be circulated and distributed onto the second roller conveyor line 120, and set the transmission speed of the second roller conveyor line 120 in advance, so that the goods are transmitted on the surface of the second roller conveyor line 120. After the goods pass through the first recognition component 200, the recognition module 500 and the measurement module 600 in the first recognition component 200 respectively recognize the barcode and size of the goods, and upload the barcode and size information to the first processor 210.

[0093] S2: The barcode information and size information of the goods on the first processor 210 are uploaded to the Internet of Things terminal 220 .

[0094] S3: The IoT terminal 220 classifies the barcode information and size information of the goods, and stores the estimated size information of the goods barcode. The IoT terminal 220 matches the allocation information items stored in the second processor 410, that is, the staff sends the corresponding information of the allocation items to the second processor 410 through the IoT terminal 220, so that the second identification component 400 can identify the goods information.

[0095] S4: After the goods pass through the first identification component 200, they are transmitted along the surface of the second roller conveyor line 120, and the goods pass through the second identification component 400 in turn. The identification module 500 of the second identification component 400 reads the barcode of the goods in turn. After the barcode of the goods matches the goods distribution information stored in the second processor 410, the distribution component 300 is controlled to push out multiple flow strips 311.

[0096] S5: After the smooth strip 311 at the bottom of the goods is pushed out, the goods slide out of the surface of the second roller conveyor line 120 along the surface of the smooth strip 311 and enter the surface of the first roller conveyor line 110 or the third roller conveyor line 130.

[0097] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
