Description

Technical Field

[0001] The present invention relates to the technical field of cast iron pipe packing, and particularly to a ductile iron pipe packing and warehousing system and a palletizing device using the system. Background Art

[0002] In the production process of ductile iron pipes, the packing and warehousing link is crucial for ensuring product quality and improving storage and management efficiency. With the development of the industry, many problems have emerged in the traditional ductile iron pipe packing and warehousing process, which urgently need to be solved.

[0003] In terms of transportation, due to the diverse specifications of ductile iron pipes and different outer diameters affected by the socket joints, conventional equipment cannot ensure the stable transportation of pipes of different specifications, and it is easy to cause slipping, collision, and damage to products. During sorting, it is difficult for manual workers to quickly and accurately collect and classify a large amount of pipe code information, which is prone to errors and leads to chaotic classification. During palletizing operations, manual palletizing has a high labor intensity, low efficiency, and poor stability. When stacking multiple layers, it is difficult to ensure neat arrangement and add supports, posing safety hazards and wasting warehouse space.

[0004] In addition, the entire packing and warehousing system lacks an effective automatic control and coordination mechanism. Each link is independent and cannot achieve information sharing and coordinated operation, resulting in problems such as process conflicts and low efficiency during the production process. For example, it is difficult to coordinate the working rhythms of the transportation, sorting, and palletizing links, and there are often situations of excessive waiting time or chaotic operations. Moreover, the traditional system is difficult to effectively interface with the enterprise's information management system, which is not conducive to real-time monitoring and management of the production process and inventory. When quality problems occur in products, it is also difficult to conduct rapid traceability. Summary of the Invention

[0014] The present invention also discloses a ductile iron pipe packing and warehousing system, including the following technological steps: Step 1, preliminary preparation work: The ductile iron pipe fittings to be packed and warehoused are subjected to aperture detection, label identification, and spraying identification operations on the pipe fittings through existing pipe diameter detection devices, pipe fitting label identification devices, and automatic spraying of identification and two-dimensional codes, collect the basic information of the pipe fittings, and complete classification identification; Step 2: Place the pipe fittings completed in the preliminary preparation work on the conveying mechanism. Through the coordinated work of the conveying mechanism, the ductile iron pipes can be transported smoothly. After the pipe fittings move onto the intermittent blanking component, the pipe fittings on the blanking support plate can be surrounded and intermittently blanked, so that the blanking efficiency of the pipe fittings can be adjusted according to the subsequent technological process, avoiding conflicts with the subsequent technological process; Step 3: After the pipe fittings are transported to the sorting mechanism by the conveying mechanism, the clamping and blanking component near the intermittent blanking component will clamp and fix the pipe fittings. At this time, the industrial camera mounted on the top of the support plate by the tripod will identify and collect the identification and two-dimensional code of the pipe fittings clamped inside the clamping and blanking component, and classify and transport them to the corresponding pipe fitting transportation mechanism according to the pipe fitting identification, and put the pipe fittings into the pipe fitting transportation mechanism. While the clamping and blanking component rotates away, another adjacent clamping and blanking component will rotate to its original position, so as to continuously classify and transport the pipe fittings; Step 4: After classifying and transporting different pipe fittings to different pipe fitting transportation mechanisms, the pipe fittings in the pipe fitting transportation mechanism are of the same specification, which is convenient for the transfer mechanism to transfer the pipe fittings. Taking the pipe fitting transportation mechanism, automatic lifting and adding wooden strip mechanism, and transfer mechanism located on the right side of the sorting mechanism as an example, when the pipe fittings enter the inside of the pipe fitting transportation mechanism, the vertical plate will surround the pipe fittings on the top of the transport roller. After the pipe fittings are stacked side by side to meet the stacking requirements, generally three pipe fittings are arranged side by side or five pipe fittings are arranged side by side, and specific adjustments need to be made according to the different specifications of the pipe fittings. At this time, through the mutual cooperation of the second electric lifting cylinder body and the automatic electromagnetic crane in the transfer mechanism, multiple side-by-side pipe fittings can be adsorbed and transferred to the top of the platen in the automatic lifting and adding wooden strip mechanism. After stacking a layer of pipe fittings on the top of the platen, the automatic wooden strip adding component adds supporting wooden strips to the top of the pipe fittings, and through the mutual cooperation of the first electric lifting cylinder body, bevel gears, bevel gear disks, and rotating blocks, the top plate can be driven to lift and rotate at the same time, so as to continue stacking the pipe fittings; Step 5. After completing the palletizing of pipe fittings, use existing equipment to tie the palletized pipe stacks with steel straps, and then transport the pipe stacks with steel straps through an AGV cart into the pipe storage, thus completing the packaging and warehousing operation of the pipe fittings. At the same time, the information of the pipe stacks sent to the pipe storage will be synchronously transmitted to the database of the pipe storage and the enterprise's ERP or MES system, so as to trace the pipe fitting data according to the pipe fitting number and QR code in case of unqualified pipe fittings subsequently.

[0015] As a further solution of the present invention, the system is equipped with an industrial control computer using a programmable logic controller to automatically control the operation of various devices during the equipment production process. Moreover, the system uses IO-link sensors, which have a self-diagnosis function. When the sensor has a broken wire or is damaged, an alarm message will be generated, facilitating maintenance personnel to quickly handle problems and reducing the maintenance time. At the same time, the system is divided into manual and automatic operation modes. In the automatic mode, no manual operation is required, and the equipment runs fully automatically, reducing manual intervention and improving production efficiency. Additionally, it can be connected to the MES and ERP systems of its own unit to receive production instructions, input of process parameters, and real-time upload of production processes and results in real time, realizing intelligent control.

[0016] Advantages of the present invention: (1) High-efficiency and stable transportation: In the conveying mechanism, the spring strut and the convex plate cooperate with each other, and can freely adjust the support height according to the outer diameter of the non-joint end of the ductile iron pipe, enabling stable transportation of ductile iron pipes of different specifications. The intermittent blanking component can intermittently blank the ductile iron pipes according to the sorting process of the sorting mechanism, avoiding working conflicts and ensuring stable and orderly transportation of pipe fittings.

[0017] (2) Precise sorting and classification: The sorting mechanism collects the pipe fitting code information through an industrial camera, can accurately determine which direction of the pipe fitting transportation mechanism the pipe fittings should be placed in, and at the same time, the clamping and blanking components can stably clamp and accurately place the pipe fittings, realizing efficient classified transportation of pipe fittings and improving the accuracy and efficiency of sorting.

[0018] (3) Convenient palletizing operation: The pipe fitting transportation mechanism can stack the pipe fittings side by side. The transfer mechanism can transfer the pipe fittings stacked side by side to the top of the automatic lifting and wooden strip adding mechanism. The automatic lifting and wooden strip adding mechanism can realize the lifting, rotation of the pipe fittings and automatic addition of supporting wooden strips, facilitating multi-layer palletizing, making the palletizing operation more convenient and efficient, and ensuring the stability and quality of palletizing.

[0019] (4)System collaborative intelligence: The workflow of the entire packing and warehousing system is coherent and each part collaborates closely. In the preliminary preparation work, the pipe fittings are comprehensively inspected and marked by existing devices, and subsequent agencies cooperate to complete packing and warehousing. The system uses a programmable logic controller equipped with an industrial control computer, which can automatically control the operation of the equipment, and the IO-link sensor has a self-diagnosis function, which is convenient for maintenance. In addition, the system has manual and automatic operation modes. The automatic mode reduces manual intervention, can be connected to MES and ERP systems, realizes intelligent control, improves production efficiency, and facilitates data management and traceability.

[0020] (5)Through the coordinated work of the above-mentioned mechanisms, the equipment can adjust the support height according to the pipe diameter, combine with the intermittent feeding component to avoid working conflicts, and achieve stable and efficient transportation; the sorting mechanism uses an industrial camera to collect the standard codes, and cooperates with the clamping and feeding components to accurately classify and transport the pipe fittings; the palletizing operation is completed conveniently, ensuring the stability and quality of palletizing; the entire system has a coherent workflow, sufficient preliminary preparation, uses a programmable logic controller and an IO-link sensor with self-diagnosis function, has manual and automatic modes, can be connected to MES and ERP systems, realizes intelligent control, improves production efficiency, and facilitates data management and traceability.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] Please refer to Figures 1 - 2 As shown, the present invention is a palletizing device for packing and storing ductile iron pipes, including a conveying mechanism 1. The conveying mechanism 1 is used for transporting the pipes after the basic data of the pipes are collected and spray-coded. A sorting mechanism 2 is arranged on the right side of the conveying mechanism 1. The sorting mechanism 2 is used for identifying the codes of the pipes and transporting the pipes to different pipe transporting mechanisms 3 according to the codes. Pipe transporting mechanisms 3, an automatic lifting and wood-strip adding mechanism 4, and a transfer mechanism 5 are arranged on the front surface, right side, and back of the sorting mechanism 2. The pipe transporting mechanism 3 is used for arranging the pipes transported into it side by side. An automatic lifting and wood-strip adding mechanism 4 is arranged outside the pipe transporting mechanism 3. The automatic lifting and wood-strip adding mechanism 4 is used for palletizing the pipes. A transfer mechanism 5 is arranged at the top of the pipe transporting mechanism 3 and the automatic lifting and wood-strip adding mechanism 4. The transfer mechanism 5 is used for transferring the pipes stacked side by side in the pipe transporting mechanism 3 to the top of the automatic lifting and wood-strip adding mechanism 4; The conveying mechanism 1 includes a conveyor housing 101, which is used to support the chain plate conveyor belt 103 and can enclose the ductile iron pipe to prevent it from rolling off the side of the chain plate conveyor belt 103 during transportation. A plurality of brackets 102 are fixedly connected to the bottom of the conveyor housing 101, and the brackets 102 are used to support and fix the conveyor housing 101. The conveyor housing 101 is rotatably connected to the chain plate conveyor belt 103 inside, and the chain plate conveyor belt 103 is used to transport the pipes placed thereon. The first transmission gear box 104 is threadedly connected to the right side of the front surface of the conveyor housing 101 through a flange, and the first motor 105 is threadedly connected to the left side of the first transmission gear box 104 through a flange. The first motor 105 provides power to the chain plate conveyor belt 103 through the first transmission gear box 104. A plurality of spring struts 106 are fixedly connected to the rear end of the outer wall of the chain plate conveyor belt 103. The spring struts 106 are used to support the convex plate 107, and the supporting height of the support plate can be freely adjusted. The top of the rod 106 is fixed with a convex plate 107, which is used to support a section of the outer wall of the ductile iron pipe. Since a section of the ductile iron pipe is provided with a socket, the outer diameter of the portion with the socket is larger than the outer diameter of the other end. Through the cooperation between the spring support rod 106 and the convex plate 107, the non-socket portions of ductile iron pipes of different specifications can be supported so that they can be transported stably on the top of the chain plate conveyor belt 103. An intermittent unloading component 1 is provided on the right side of the conveyor housing 101. 08. The intermittent unloading component 108 is used to intermittently unload the ductile iron pipes transported to the top thereof, so that the ductile iron pipes can be delivered according to the sorting process of the sorting mechanism 2 to avoid conflicts between the working processes of the two, which would cause the delivered pipes to fall off the sorting mechanism 2. The output shaft on the back of the first transmission gear box 104 is fixedly connected to the front surface of the rightmost transmission roller inside the chain plate conveyor belt 103, and the transmission shaft on the left side of the first transmission gear box 104 is fixedly connected to the output shaft on the right side of the first motor 105.

[0026] In this embodiment, preferably, the intermittent blanking member 108 includes a trough plate 1081. The trough plate 1081 is used to fix the blanking support plate 1083 and can support the shaft rod 1084, enabling the shaft rod 1084 to rotate on one side inside it. Legs 1082 are fixedly connected to the four corners at the bottom end of the trough plate 1081. The legs 1082 are used to support the trough plate 1081. A plurality of blanking support plates 1083 are fixedly connected to the inner side of the top end of the trough plate 1081. The blanking support plates 1083 are used to support the pipe fittings transported out from the top end of the chain plate conveyor belt 103 and enable the pipe fittings to roll to the side of the L-shaped baffle 1086. A shaft rod 1084 is rotatably connected to the inside of the right side of the trough plate 1081. The shaft rod 1084 is used to fix a plurality of L-shaped baffles 1086 and can drive the L-shaped baffles 1086 to rotate together while the shaft rod 1084 rotates. A first servo motor 1085 is connected to the front surface on the right side of the trough plate 1081 through a speed reducer. The first servo motor 1085 is used to provide power to the shaft rod 1084, enabling it to rotate in the positive or negative direction inside the trough plate 1081. A plurality of L-shaped baffles 1086 are fixedly connected at equal intervals on the outer wall. The L-shaped baffles 1086 are used to enclose the pipe fittings on their sides. And when the shaft rod 1084 drives the L-shaped baffles 1086 to rotate, the enclosure of the pipe fittings will be cancelled, enabling the pipe fittings to roll to the inside of its corner. And when the shaft rod 1084 drives the L-shaped baffles 1086 to rotate in the reverse direction, the pipe fittings inside it will be put into the sorting mechanism 2. At the same time, when the L-shaped baffles 1086 reset, the side of the L-shaped baffles 1086 will enclose the pipe fittings located on its side again, so that only one pipe fitting can be blanked each time it rotates in the positive and negative directions, thus achieving the purpose of intermittent blanking.

[0027] In this embodiment, preferably, the left side of the trough plate 1081 is attached to the right side of the conveyor housing 101. The left sides of the two central blanking support plates 1083 among the plurality of blanking support plates 1083 are attached to the right side of the chain plate conveyor belt 103, and the height of the top ends of the left sides of the two central blanking support plates 1083 is flush with the top end height of the chain plate conveyor belt 103.

[0028] In summary, after the pipe fittings undergo initial data collection and inkjet identification, the preliminarily processed pipe fittings are placed into the transportation mechanism. Through the mutual cooperation of the spring strut 106 and the convex plate 107 in the transportation mechanism, ductile iron pipe fittings of different specifications can be stably transported, and the pipe fittings are transported to the top of the intermittent blanking member 108. When the pipe fitting moves to the top of the blanking support plate 1083 in the intermittent blanking member 108, since the top of the blanking support plate 1083 is processed into an inclined surface on the side close to the sorting mechanism 2, when the pipe fitting moves to its top, the pipe fitting will roll to the side of the L-shaped baffle 1086. Through the mutual cooperation of the reduction box and the first servo motor 1085, the shaft rod 1084 can be driven to slowly rotate inside the groove plate 1081. When the shaft rod 1084 drives the L-shaped baffle 1086 to rotate in the positive direction, the corner of the L-shaped baffle 1086 will slowly rotate towards the position of the blanking support plate 1083. After the L-shaped baffle 1086 rotates to a certain extent, the pipe fitting originally enclosed on its side will roll to the inside of the corner of the L-shaped baffle 1086. Then the first servo motor 1085 drives the shaft rod 1084 to rotate in the reverse direction. When the L-shaped baffle 1086 returns to its original position, the pipe fitting at the inside of the corner of the L-shaped baffle 1086 will roll from its top into the sorting mechanism 2, and the reset L-shaped baffle 1086 will enclose the next pipe fitting again, so as to achieve the purpose of intermittent blanking of the pipe fittings.

At the center of the top end of the bottom plate 201, there is a fixedly connected support groove tube 202, which is used for supporting the shaft disc 203. At the top end of the support groove tube 202, there is a fixedly connected shaft disc 203, which is used for supporting the support disc 205 and can drive the support disc 205 to rotate. At the center of the bottom end of the shaft disc 203, there is a step motor 204 connected by a flange and thread, which is used to provide power to the shaft disc 203, so that the shaft disc 203 can drive the support disc 205 to rotate within a range of 90° each time. The top end of the shaft disc 203 is rotatably connected to the support disc 205, which is used for installing the clamping and blanking member 208. At the center of the top end of the support disc 205, there is a tripod 206 connected by bolts and threads, which is used for fixing the industrial camera 207. At the top end of the tripod 206, there is a fixedly connected industrial camera 207, which is used for collecting the code information of the pipe fittings from the delivery point of the transportation mechanism and determining which direction of the pipe fitting transportation mechanism 3 the pipe fittings should be delivered to according to the collected code information. A plurality of clamping and blanking members 208 are arranged in a circular array around the inner circumference of the support disc 205. The clamping and blanking members 208 are used for clamping the pipe fittings delivered from the intermittent blanking member 108, and after rotating to the position of the pipe fitting transportation mechanism 3 that matches the pipe fittings, cancel the clamping of the pipe fittings and deliver the pipe fittings into the pipe fitting transportation mechanism 3.

The clamping plate 2082 is used to center and clamp the end of the pipe fitting, so as to clamp and fix the pipe fitting onto the support frame 2083, and prevent the pipe fitting from being thrown off from its top when the support frame 2083 rotates. Two support frames 2083 are fixedly connected to the center of the top of the guide rail 2081. Through the mutual cooperation with the blanking frame 2084, the support frame 2083 can clamp the pipe fitting that falls onto its top. The blanking frame 2084 is slidably connected to the front surface of both support frames 2083. The blanking frame 2084 can surround the pipe fitting clamped on the top of the support frame 2083. A connecting plate 2085 is rotatably connected to the top of the front surface of each support frame 2083 and the top of the back of each blanking frame 2084. The connecting plate 2085 is used to connect the top of the support frame 2083 and the blanking frame 2084 together after the blanking frame 2084 shrinks to the bottom side of the support frame 2083, so that the pipe fitting originally clamped on the top of the support frame 2083 can smoothly roll through the connecting plate 2085 into the pipe fitting transportation mechanism 3. An electric telescopic rod 2086 is fixedly connected to the bottom of each blanking frame 2084 near the front end of the support frame 2083. The electric telescopic rod 2086 is used to drive the blanking frame 2084 to lift and lower. Spring pressure rods 2087 are fixedly connected to the outer sides of both clamping plates 2082. The spring pressure rods 2087 are used to squeeze the clamping plates 2082. After the extrusion top block 20810 cancels the extrusion of the wedge-shaped slider 2089, the clamping plate 2082 can be clamped to the end of the pipe fitting. A fixing plate 2088 is fixedly connected to the outer side of each spring pressure rod 2087. The fixing plate 2088 is used to fixedly support the outer side of the spring pressure rod 2087. Wedge-shaped sliders 2089 are fixedly connected to the bottom ends of the backs of both clamping plates 2082. The wedge-shaped sliders 2089 are used to drive the clamping plates 2082 to move. An extrusion top block 20810 is arranged in a fitting manner at the bottom end of each wedge-shaped slider 2089. The extrusion top block 20810 is used to drive the wedge-shaped slider 2089 to slide inside the chute. An electric telescopic rod 20811 is fixedly connected to the bottom end of each extrusion top block 20810. The electric telescopic rod 20811 is used to drive the extrusion top block 20810 to lift and lower. The guide rail 2081 is fixedly connected to the top of the support disk 205. The bottom end of the electric telescopic rod 2086 is fixedly connected to the bottom end of the front surface of the guide rail 2081. The bottom end of the fixing plate 2088 is fixedly connected to the top of the support disk 205. The middle section of the outer wall of the wedge-shaped slider 2089 is slidably connected inside the chute. The bottom end of the electric telescopic rod 20811 is fixedly connected to the outer wall top around the bottom plate 201.

[0033] In summary, when the pipe fitting is placed on the top of the sorting mechanism 2 through the intermittent feeding member 108, the electric telescopic rod II 20811 in the clamping and feeding member 208 corresponding to the intermittent feeding member 108 is in a released state. At this time, the extrusion top block 20810 will extrude the wedge-shaped slider 2089 outwards, thereby driving the clamping plate 2082 to expand outwards through the wedge-shaped slider 2089, so that the pipe fitting can roll smoothly to the top of the support frame 2083. At the same time, the industrial camera 207 will collect the code information of the pipe fitting, so as to determine which pipe fitting transportation mechanism 3 the pipe fitting should be transported to. After the pipe fitting rolls onto the support frame 2083, the electric telescopic rod II 20811 contracts, and the extrusion top block 20810 cancels the extrusion of the wedge-shaped slider 2089. Through the operation of the spring pressure rod 2087, the clamping plate 2082 can be reset and clamped on the outer wall of the pipe fitting to prevent the pipe fitting from slipping off the support frame 2083 during rotation. After the industrial camera 207 collects the code information and determines which pipe fitting transportation mechanism 3 the pipe fitting should be placed in, when the clamping and feeding member 208 rotates to the corresponding position, the electric telescopic rod II 20811 rises again. Through the mutual cooperation of the extrusion top block 20810 and the wedge-shaped slider 2089, the clamping of the end of the pipe fitting by the clamping plate 2082 can be cancelled. Then the electric telescopic rod I 2086 contracts, driving the feeding frame 2084 to slide to the side bottom end of the support frame 2083, canceling the enclosure of the pipe fitting. At this time, the pipe fitting will roll through the connecting plate 2085 into the pipe fitting transportation mechanism 3. After the clamping and feeding member 208 holding the pipe fitting rotates away from the side of the intermittent feeding member 108, the next clamping and feeding member 208 will rotate to the side of the intermittent feeding member 108, so as to continue to place the pipe fitting inside it, so as to achieve the purpose of continuous sorting of the pipe fitting.

[0040] In summary, after the pipes with the same specification and code are transported to the pipe transport mechanism 3 located in the same position, the automatic lifting and adding wooden strip mechanism 4 and the transfer mechanism 5, the pipes entering the interior can be enclosed by the operation of the baffle plate, and since the sorting mechanism 2 is continuously working, pipes will always be transported to the pipe transport mechanism 3. When a certain number of pipes are arranged side by side, the second electric lifting cylinder 505 in the transfer mechanism 5 located at the top of the pipe transport mechanism 3 starts to work, so that the bottom end of the automatic electromagnetic crane 506 can be attached to the top of multiple pipes arranged side by side. Through the operation of the automatic electromagnetic crane 506, multiple pipes can be The pipes are sucked up together, and the second electric lifting cylinder 505 returns to its original position at this time. The work of the servo motor 509 can drive the screw rod 508 to rotate. During the rotation of the screw rod 508, the sleeve 512 connected to its outer wall thread will drive the slide plate 504 to move together, so that the automatic electromagnetic hanger 506 and the multiple pipes adsorbed at the bottom are transported to the top of the clapper board in the automatic lifting and adding wooden strip mechanism 4. Then the second electric lifting cylinder 505 descends. After the pipes are stacked on the clapper board, the automatic electromagnetic hanger 506 cancels the adsorption of the pipes, and returns to its original position through the cooperation of the screw rod 508, the sleeve 512 and other components, and then the next The plurality of pipe fittings arranged side by side are adsorbed. When the pipe fittings are stacked on the clapper board, the electric telescopic rod three 4115 in the automatic wooden strip component 411 starts to work, and the electric telescopic rod three 4115 drives the pushing plate 4116 to slide to the other side of the storage hopper 4113. During the sliding process of the pushing plate 4116, the supporting wooden strip originally stuck in the storage hopper 4113 is withdrawn from the interior thereof, and the wooden strip is slid to the top of the outer wall of the pipe fitting, and then the electric telescopic rod three 4115 drives the pushing plate 4116 to return to the original position together. Because the supporting wooden strips are stacked inside the storage hopper 4113, when the pushing plate 4116 returns to its original position, the supporting wooden strips pushed out Another set of supporting wooden strips at the top of the supporting wooden strips will fall back to the inner bottom end of the storage hopper 4113, so that the supporting wooden strips can be pushed to the top of the pipe fittings again. After the supporting wooden strips are placed on the top of the stacked pipe fittings, the stepper motor 2 405 drives the bevel gear 406 to rotate through the third transmission gear box 404. When the bevel gear 406 rotates, it can drive the bevel gear disc 407 to rotate together, thereby driving the rotating block 408 to rotate together through the bevel gear disc 407, and driving the clapboard placed on the top of the sliding ball 410 to rotate together, so that another layer of pipe fittings can be stacked on the top again. After repeating several times, the stacking operation of the pipe fittings can be completed, so that the pipe stack can be subsequently tied with steel belts.

[0041] Embodiment 4

[0042] See also Figures 1 - 13As shown, by combining Embodiment 1, Embodiment 2, and Embodiment 3, this embodiment is obtained. The working process of the present invention is coherent and each part cooperates closely. After the pipe fittings are subjected to initial data collection and inkjet coding recognition, they are placed on the conveying mechanism 1. The conveyor housing 101 of the conveying mechanism 1 supports the chain plate conveyor belt 103, and its bottom bracket 102 stabilizes the fuselage. The first motor 105 drives the chain plate conveyor belt 103 to operate through the first transmission gearbox 104. The spring strut 106 at the rear end of the outer wall of the chain plate conveyor belt 103 cooperates with the top convex plate 107, and can freely adjust the support height according to the outer diameter of the non-joint end of the ductile iron pipe to ensure the stable transportation of pipe fittings of different specifications. When the pipe fittings are transported to the intermittent blanking member 108, this member starts to work. The trough plate 1081 of the intermittent blanking member 108 fixes the blanking support plate 1083 and supports the shaft rod 1084, and the trough plate 1081 is supported by the support legs 1082. After the pipe fittings are transported from the chain plate conveyor belt 103 to the top of the blanking support plate 1083, because the side of the blanking support plate 1083 close to the sorting mechanism 2 is an inclined surface, the pipe fittings roll to the side of the L-shaped baffle. The servo motor 1085 drives the shaft rod 1084 to rotate through the speed reducer, and the shaft rod 1084 drives the L-shaped baffle to rotate. When the L-shaped baffle rotates forward, the pipe fittings roll to the inner side of its corner; when it rotates backward, the pipe fittings are dropped into the sorting mechanism 2, and the reset L-shaped baffle encloses the next pipe fitting to achieve intermittent blanking and avoid conflicts with the work of the sorting mechanism 2.

[0043] The pipe fittings are dropped from the intermittent blanking member 108 to the top of the sorting mechanism 2. At this time, in the corresponding clamping and blanking member 208, the electric telescopic rod 20811 is in the released state, and the extrusion top block 20810 extrudes the wedge-shaped slider 2089 outwards, driving the clamping plate 2082 to expand, so that the pipe fittings roll smoothly to the top of the support frame 2083. The industrial camera 207 synchronously collects the pipe fitting code information and determines the direction of the pipe fitting transportation mechanism 3 to which it should be dropped. After the pipe fittings roll to the support frame 2083, the electric telescopic rod 20811 contracts, and the spring pressure rod 2087 pushes the clamping plate 2082 to reset and clamp the outer wall of the pipe fittings. After the industrial camera 207 determines the pipe fitting dropping position, when the clamping and blanking member 208 rotates to the corresponding position, the electric telescopic rod 20811 rises, and the extrusion top block 20810 and the wedge-shaped slider 2089 cooperate to loosen the end of the pipe fittings by the clamping plate 2082. Then, the electric telescopic rod 2086 contracts, driving the blanking frame 2084 to slide to the bottom side of the support frame 2083 to cancel the enclosure of the pipe fittings, and the pipe fittings roll through the connecting plate 2085 to the pipe fitting transportation mechanism 3. After the previous clamping and blanking member 208 rotates away, the next one rotates to the side of the intermittent blanking member 108 to continuously sort the pipe fittings.

[0044] Pipe fittings with the same specification codes are transported to the pipe fitting transportation mechanism 3 in the same direction. The transportation trough 301 of the transportation mechanism is supported by the feet 302, and the internal transportation rollers 303 are rotatably connected. The second motor 307 drives the transportation rollers 303 to rotate through the second transmission gearbox 306, the transmission wheel 304, and the transmission belt 305. The vertical plate 308 in the transportation trough 301 fences the pipe fittings to make them arranged side by side. When the pipe fittings are arranged side by side to a certain number, the transfer mechanism 5 starts to operate. The gantry 501 of the transfer mechanism 5 is supported by the support rods 502, and the sliding plate 504 in the slide rail 503 slides through the pulley. The sliding plate 504 fixes the second electric lifting cylinder body 505, and the bottom end of the cylinder body is connected to the automatic electromagnetic crane 506. The second electric lifting cylinder body 505 works, and the automatic electromagnetic crane 506 adheres to and lifts multiple pipe fittings arranged side by side, and then rises. The servo motor two 509 drives the lead screw 508 to rotate, and the lead screw 508 drives the sliding plate 504 through the sleeve 512, transporting the automatic electromagnetic crane 506 and the pipe fittings to the top of the clapper of the automatic lifting and adding wooden strip mechanism 4. The second electric lifting cylinder body 505 descends, and the pipe fittings are stacked on the clapper. The automatic electromagnetic crane 506 cancels the adsorption and resets. After the pipe fittings are stacked on the clapper, the automatic wooden strip adding component 411 works. The fixing frame 4111 of the automatic wooden strip adding component 411 supports the support plate 4112, the support plate 4112 fixes the storage hopper 4113, and the storage hopper 4113 stores the support wooden strips. The electric telescopic rod three 4115 drives the pushing plate 4116 to push the support wooden strips out of the storage hopper 4113 and place them on the top of the outer wall of the pipe fittings, and then resets. The upper wooden strips in the storage hopper 4113 fall to the bottom for the next push. After placing the support wooden strips, the stepping motor two 405 drives the bevel gear 406 to rotate through the third transmission gearbox 404. The bevel gear 406 drives the bevel gear disk 407, and then drives the rotating block 408 and the clapper to rotate, facilitating the stacking of the upper layer of pipe fittings again. Repeating the operation completes the stacking of the pipe fittings, preparing for the subsequent steel belt bundling.

[0045] Embodiment Five

[0046] Please refer to Figures 1 - 13 As shown in the figure, the present invention also provides a ductile iron pipe packing and warehousing system, including the following technological steps: Step 1. Preliminary preparation work: The ductile iron pipe fittings to be packed and warehoused are subjected to hole diameter detection, label identification, and spraying identification operations through the existing pipe diameter detection device, pipe fitting label identification device, and automatic spraying of identification and two-dimensional code device, collect the basic information of the pipe fittings, and complete the classification and identification; Step 2: Place the pipe fittings after the preliminary preparation operation on the conveying mechanism 1. Through the coordinated work of the conveying mechanism 1, the ductile iron pipes can be transported smoothly. After the pipe fittings move onto the intermittent blanking member 108, the pipe fittings on the blanking support plate 1083 can be surrounded and intermittently blanked, so that the blanking efficiency of the pipe fittings can be adjusted according to the subsequent process, avoiding conflicts with the subsequent process; Step 3: After the pipe fittings are transported to the sorting mechanism 2 by the conveying mechanism 1, the clamping and blanking member 208 near the intermittent blanking member 108 will clamp and fix the pipe fittings. At this time, the industrial camera 207 mounted on the top of the support plate 205 by the tripod 206 will identify and collect the identification and QR code of the pipe fittings clamped inside the clamping and blanking member 208, and classify and transport them to the corresponding pipe fitting transportation mechanism 3 according to the pipe fitting identification, and put the pipe fittings into the pipe fitting transportation mechanism 3. While the clamping and blanking member 208 rotates away, another adjacent clamping and blanking member 208 will rotate to its original position, so as to continuously classify and transport the pipe fittings; Step 4: After classifying and transporting different pipe fittings to different pipe fitting transportation mechanisms 3, the pipe fittings in the pipe fitting transportation mechanism 3 are of the same specification, which is convenient for the transfer mechanism 5 to transfer the pipe fittings. Taking the pipe fitting transportation mechanism 3, the automatic lifting and adding wooden strip mechanism 4 and the transfer mechanism 5 on the right side of the sorting mechanism 2 as an example, when the pipe fittings enter the pipe fitting transportation mechanism 3, the vertical plate 308 will surround the pipe fittings on the top of the transport roller 303. After the pipe fittings are stacked side by side to meet the palletizing requirements, generally three pipe fittings are arranged side by side or five pipe fittings are arranged side by side, and specifically it needs to be adjusted according to the different specifications of the pipe fittings. At this time, through the mutual cooperation of the second electric lifting cylinder 505 and the automatic electromagnetic crane 506 in the transfer mechanism 5, multiple side-by-side pipe fittings can be adsorbed and transferred to the top of the platen in the automatic lifting and adding wooden strip mechanism 4. After stacking a layer of pipe fittings on the top of the platen, the automatic wooden strip adding member 411 adds support wooden strips to the top of the pipe fittings, and through the mutual cooperation of the first electric lifting cylinder 401, the bevel gear 406, the bevel gear disk 407 and the rotating block 408, the top plate 409 can be driven to lift and rotate at the same time, so as to continue palletizing the pipe fittings; Step 5: After completing the palletizing of the pipe fittings, use existing equipment to tie the palletized pipe stacks with steel belts, and then transport the pipe stacks with steel belts to the pipe warehouse by an AGV trolley, then the packing and warehousing operation of the pipe fittings can be completed. At the same time, the information of the pipe stacks sent to the pipe warehouse will be synchronously transmitted to the database of the pipe warehouse and the enterprise's ERP or MES system, so as to trace the pipe fitting data according to the pipe fitting number and QR code in case of unqualified pipe fittings in the future.

9. A ductile iron pipe packaging and storage system, characterized in that: The use of the stacking equipment for packaging and warehousing ductile iron pipes according to claim 1 comprises the following process steps: Step 1: Preliminary preparation: The ductile iron pipe fittings to be packaged and stored are subjected to bore diameter detection, label recognition, and spray marking operations through the existing pipe diameter detection device, pipe fitting label recognition device, and automatic spray marking and QR code device, and the basic information of the pipe fittings is collected and classified and marked; Step 2: Place the pipes after the preliminary preparation work on the conveying mechanism. Through the cooperation of the conveying mechanism, the ductile iron pipes can be transported smoothly. After the pipes are moved to the intermittent unloading component, the pipes on the unloading support plate can be enclosed and unloaded intermittently, so that the unloading efficiency of the pipes can be adjusted according to the subsequent process to avoid conflicts with the subsequent process. Step 3: After the pipe is transported to the sorting mechanism via the conveying mechanism, the clamping and unloading components near the intermittent unloading components will clamp and fix the pipe. At this time, the industrial camera mounted on the top of the support plate by a tripod will identify the identification and QR code of the pipe clamped inside the clamping and unloading components for collection, and classify and transport it to the corresponding pipe transport mechanism according to the pipe identification, and put the pipe into the pipe transport mechanism. When the clamping and unloading component is turned away, another clamping and unloading component adjacent to it will rotate to its original position, so that the pipes can be continuously classified and transported; Step 4. After different pipes are classified and transported to different pipe transport mechanisms, the pipes in the pipe transport mechanism are of the same specifications, which facilitates the transfer mechanism to transfer the pipes. Take the pipe transport mechanism, automatic lifting and adding wood strip mechanism and transfer mechanism located on the right side of the sorting mechanism as an example. When the pipes enter the pipe transport mechanism, the vertical plate will block the pipes on the top of the transport roller. After the pipes are stacked side by side to meet the stacking requirements, generally three pipes are arranged side by side or five pipes are arranged side by side. The specific requirements are based on the pipes. The pipes are adjusted according to the different specifications of the pipes. At this time, through the cooperation of the second electric lifting cylinder and the automatic electromagnetic crane in the transfer mechanism, multiple pipes arranged side by side can be adsorbed and transferred to the top of the clapper board in the automatic lifting and adding wooden strip mechanism. After a layer of pipes is stacked on the top of the clapper board, the automatic adding wooden strip component adds supporting wooden strips to the top of the pipes. The cooperation of the first electric lifting cylinder, the bevel gear, the bevel gear disc and the rotating block can drive the top plate to rise and fall while driving it to rotate, so as to continue to stack the pipes. Step 5. After completing the stacking of the pipe fittings, the stacked pipes are tied with steel bands through existing equipment, and then the pipes with steel bands are transported to the pipe warehouse through the AGV cart. The packaging and warehousing of the pipe fittings are completed. At the same time, the information of the pipe stacks sent to the pipe warehouse will be synchronously transmitted to the database of the pipe warehouse and the company's ERP or MES system, so that the pipe data can be traced according to the pipe number and QR code in the event of unqualified pipe fittings in the future.

10. A ductile iron pipe packaging and storage system according to claim 9, characterized in that: This system uses a programmable controller equipped with an industrial computer to automatically control the operation of various equipment during the production process. The system uses IO-link sensors, which have self-diagnosis functions. When the sensor is disconnected or damaged, an alarm message will be generated to facilitate maintenance personnel to quickly deal with problems and reduce maintenance time. At the same time, the system is divided into manual and automatic operation modes. In automatic mode, no manual labor is required, and the equipment runs automatically, reducing manual intervention and improving production efficiency. It can also be connected to the MES and ERP systems of its own unit to receive production instructions, process parameter inputs, and real-time upload of production processes and results to achieve intelligent control.
