For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0032] like Figures 1 to 3 As shown, the embodiment of the present application introduces an automatic pipeline coding device mainly used in the train production process, which is used to automatically code the pipeline to realize automatic pipeline transportation and automatic coding operation on the transported pipeline, thereby achieving the effect of automatic pipeline coding and reducing manual operation intervention. In the embodiment of the present application, the automatic pipeline coding device includes: an automatic pipeline transportation system composed of a feeding mechanism 1, a conveying mechanism 2 and a discharge vehicle 5; also includes a coding device 3 and a code reading device 4; the coding device 3 is installed on the conveying mechanism 2 and is used to code the pipeline conveyed by the conveying mechanism 2; the code reading device 4 is installed on the conveying mechanism 2 and is located downstream of the coding device 3, and is used to read the coded pipeline conveyed by the conveying mechanism 2.

[0033] Through the above settings, different pipelines can be automatically transported and automatically coded and marked during the transportation process, achieving the effect of automatically coding and marking multiple pipelines separately; at the same time, through the above settings, the pipelines after coding and marking can be read and identified again, so as to realize automatic code reading and error judgment of the automatic coding on the pipeline, thereby achieving a significant technical progress in improving the accuracy of pipeline coding.

[0034] like Figures 1 to 3 As shown, in the embodiment of the present application, the conveying mechanism 2 includes a conveyor belt structure 22, on which a plurality of fixed structures 222 are arranged at intervals, each of which is used to fix the conveying pipeline; in the conveying direction of the conveyor belt structure 22, the coding device 3 is arranged in the middle area of ​​the conveyor belt structure 22; the coding structure 31 of the coding device 3 is located above the conveyor belt structure 22, and the coding structure 31 is arranged downward to perform coding operations on the conveying pipeline. The coding structure 31 can be any structure in the prior art that can perform coding operations on the outer wall of the pipeline, such as: a laser marking probe for laser coding printing, an inkjet probe for inkjet coding spraying, etc.

[0035] Of course, the pipeline automatic coding equipment also includes a control system; the control system can automatically generate a code corresponding to the transmitted pipeline, and control the coding structure 31 to directly perform a coding operation on the transmitted pipeline with the corresponding code.

[0036] In the embodiment of the present application, the code reading device 4 is disposed downstream of the coding device 3 in the conveying direction of the conveyor belt structure 22. The code reading device 4 includes a code reading structure 41, which is located above the conveyor belt structure 22 and downstream of the coding structure 31 and is used to read the codes on the pipeline being conveyed. The code reading structure 41 can be an existing code reader capable of recognizing barcodes and QR codes. The code recognition probe is positioned toward the conveyor belt structure 22 below to automatically read the codes printed on the pipeline, automatically determining whether the pipeline coding is correct, thereby achieving a significant technological advancement in improving the accuracy of automatic coding.

[0037] In the embodiment of the present application, the height difference between the coding structure 31 and the code reading structure 41 and the conveyor belt structure 22 is respectively greater than or equal to the diameter of the conveying pipeline. This allows the fixed portion of the conveying pipeline to pass sequentially under the coding structure 31 and the code reading structure 41, preventing the coding structure 31 and the code reading structure 41 from interfering with the conveying pipeline, thereby preventing the pipeline from moving and causing problems such as inaccurate coding or reading. Optionally, the height difference between the coding structure 31 and the top of the conveying pipeline is less than the maximum clearance for coding operation, ensuring that the coding structure 31 can effectively code the outer wall of the pipeline; at the same time, the height difference between the code reading structure 41 and the top of the conveying pipeline is less than the maximum clearance for code reading operation, ensuring that the coding structure 31 can effectively read the outer wall of the pipeline.

[0038] like Figures 1 to 3 As shown, in the embodiment of the present application, a positioning device 25 is provided on the conveying mechanism 2; the positioning device 25 is provided at a position opposite to or upstream of the coding device 3, and is used to position and guide the conveying pipeline conveyed to the coding device 3 to the coding setting position, so that the coding device 3 can code the fixed part of the conveying pipeline, so that the conveying pipeline can be restricted by the positioning device 25 to a relatively fixed position, so that the coding structure 31 can effectively code the relatively fixed part of the transmission pipeline, thereby facilitating subsequent code reading, user identification and other operations.

[0039] In the embodiment of the present application, the conveying mechanism 2 includes a base 21; a conveyor belt structure 22 is mounted on the base 21, and the conveyor belt structure 22 is tensioned and sheathed between two pulleys 221. To improve transmission stability, the conveyor belt structure 22 can be configured as two parallel chain-type or belt-type conveyor belts, both of which are tensioned and sheathed on the axial ends of the pulleys 221 to effectively support the conveyed pipeline and prevent problems such as horizontal deflection of the pipeline. At the same time, a plurality of outwardly protruding fixing grooves are arranged at intervals on the outer peripheral wall of the conveyor belt structure 22, each of which constitutes a fixing structure 222 for positioning and supporting the conveyed pipeline in the conveying direction. Optionally, the fixing groove can be composed of two upwardly protruding protrusions, with the opposite sides of the two protrusions being relatively inclined, so as to form a fixing groove that narrows from top to bottom, so as to adapt to pipelines of different diameters for transmission. In addition, a motor 23 is installed on the base 21, and the output end of the motor 23 is coaxially connected to a pulley 221, which is used to drive the conveyor belt structure 22 to run along the conveying direction; generally, the output end pulley 221 of the conveyor belt structure 22 is set as the active pulley 221, and the input end pulley 221 is set as the driven pulley 221, and the output shaft of the motor 23 is coaxially connected to the output end pulley 221, and the output end pulley 221 is driven to rotate around the axis to drive the conveyor belt structure 22 to produce a conveying action.

[0040] In the embodiment of the present application, a coding device 3 and a positioning device 25 are respectively provided on opposite sides of the conveyor belt structure 22 in the vertical direction of the conveyor. These devices are used to guide the conveyor pipeline in the vertical direction of the conveyor, move it to the set coding position, and then code the fixed parts of the conveyor pipeline. At the same time, to avoid interference between the coding device 3 and the positioning device 25 and other devices, the coding device 3 and the positioning device 25 are generally located in the middle of the conveyor direction, effectively away from the loading mechanism 1 and the discharge vehicle 5 located at the feed and discharge ends.

[0041] like Figures 1 to 3 As shown, in the embodiment of the present application, the coding device 3 and the positioning device 25 respectively have a first positioning portion 251 and a second positioning portion 252; in the conveying vertical direction of the conveyor belt structure 22, the coding device 3 and the positioning device 25 respectively have a first positioning portion 251 and a second positioning portion 252 arranged opposite to each other; the first positioning portion 251 and the second positioning portion 252 are both arranged at the same height as the conveying pipeline on the upper side of the conveyor belt structure 22, and the spacing between the first positioning portion 251 and the second positioning portion 252 is greater than or equal to the circumferential length of the conveying pipeline, which is used to guide the conveying pipeline to move horizontally to between the first positioning portion 251 and the second positioning portion 252, that is, the coding setting position, so that at least part of the conveying pipeline, that is, the fixed portion, is located below the coding structure 31, so that the fixed portion of the conveying pipeline can be effectively coded.

[0042] like Figures 1 to 3 As shown, in the embodiment of the present application, a loading mechanism 1 is provided at the feed end of the conveyor belt structure 22 for inputting the pipeline to be coded; the loading mechanism 1 includes a base frame 11, on which a loading conveying structure 12 is provided, and a lifting structure 13 is provided at the output end of the loading conveying structure 12, and a discharge platform 14 is provided at the top of the lifting structure 13, and the discharge platform 14 is located above the feed end of the conveyor belt structure 22.

[0043] In the embodiment of the present application, a downwardly recessed loading trough is provided at the upper end of the base frame 11 for storing pipelines; a horizontally arranged loading conveying structure 12 is provided at the bottom of the loading trough, and the conveying direction of the loading conveying structure 12 is inclined and extends from top to bottom, and the end of the loading conveying structure 12 is at the lowest point; a lifting structure 13 is provided on the side wall of the discharge side of the loading trough, and the bottom of the lifting structure 13 is connected to the end of the loading conveying structure 12, and the fixed part is connected to the discharge platform 14, so that the pipeline conveyed by the lower loading conveying structure 12 is lifted to the discharge platform 14 and then falls onto the conveyor belt structure 22.

[0044] In the embodiment of the present application, a discharge cart 5 is provided below the discharge end of the conveyor belt structure 22 for outputting the coded pipeline; a discharge rack 24 is provided at the feed end of the conveyor belt structure 22; the discharge rack 24 extends outward and downward along the output direction from the output end of the conveyor belt structure 22, and the extended end of the discharge rack 24 protrudes from the base 21 and is located above the discharge cart 5, and is used for allowing the coded pipeline transported by the conveyor belt structure 22 to fall downward into the discharge cart 5.

[0045] like Figures 1 to 3 As shown, in the embodiment of the present application, a detection device 253 is provided on the positioning device 25, which is used to automatically detect whether the transmission pipeline reaches below the coding structure 31; the probe of the detection device 253 is located in the second positioning portion 252, and transmits a detection signal toward the first positioning portion 251; the receiving portion is provided on the first positioning portion 251 or the second positioning portion 252, and the receiving portion can receive the signal transmitted by the probe or the reflected signal, and use the change of the signal received by the receiving portion to generate a detection signal transmitted by the transmission pipeline to the positioning device 25, so as to automatically detect whether the transmission pipeline reaches below the coding structure 31.

[0046] In the embodiment of the present application, after receiving the detection signal transmitted by the conveying pipeline to the positioning device 25, the motor 23 is controlled to stop working for a set period of time, so that the pipeline above the conveyor belt structure 22 moved to the position below the coding structure 31 is subjected to the corresponding coding operation by the coding structure 31, so as to improve the coding accuracy of the automatic coding equipment and prevent the occurrence of problems such as coding deflection and coding distortion caused by pipeline displacement during the coding process.

[0047] In the embodiment of the present application, optionally, in the conveying direction, the distance between the coding structure 31 and the code reading structure 41 is equal to the distance between adjacent fixed structures 222 on the belt conveyor structure, so that any transmission pipeline moves below the coding structure 31. When the coded structure 31 performs the coding operation, the adjacent transmission pipeline on the downstream side moves below the code reading structure 41, and the code reading structure 41 performs the code reading operation, so as to realize the synchronous pause operation of coding and code reading, thereby improving the coding efficiency.

[0048] In the embodiment of the present application, the specific working process of the pipeline automatic coding equipment is as follows:

[0049] First, the pipes unloaded by the unloading machine are classified according to the same diameter and placed on the feeding conveyor structure of the loading mechanism. The lifting structure works to lift the single pipe onto the discharge platform, which is a downward slope of about 3°-5. The pipes on the discharge platform roll down to the feeding end of the conveyor mechanism by gravity.

[0050] The pipeline is fixed to the conveyor belt structure, and the motor of the conveying mechanism rotates to drive the conveyor belt structure to produce a conveying action, transporting the pipeline to the discharge end;

[0051] When the pipeline is conveyed to the bottom of the coding structure, the detection device at the positioning structure generates a detection signal, the conveyor belt structure stops conveying, and the positioning structure pushes the pipeline to the set coding position aligned between the first positioning part and the second positioning part, so that the fixed part of the pipeline is under the coding structure; the control system transmits the coding information to the coding device according to the feeding order of the pipeline, and the coding structure engraves the coding information on the fixed part of the pipeline;

[0052] After the marking is completed, the conveyor belt structure receives the signal to continue the transmission work. When the pipeline reaches the position below the code reading structure, the conveyor belt structure stops conveying and the code reading structure reads the code. After the code is read successfully, the conveying pipeline continues to run until it reaches the discharge rack, and relies on gravity to roll the pipeline onto the discharge car; if the code reading structure fails to read the code, the control system issues a prompt alarm and removes the pipeline.

[0053] The above is merely a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Although the present application has been disclosed as above with preferred embodiments, it is not intended to limit the present application. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above-mentioned technical contents without departing from the scope of the technical solution of the present application. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application are still within the scope of the solution of the present application.
