[0002] The intelligent spraying, marking, packing and warehousing process for small-diameter centrifugally cast ductile iron pipes used to be manual. For example, for spraying the mark, workers held a character template by hand and sprayed the characters manually; no two-dimensional code was sprayed; for stacking, technicians operated a crane and stacked them manually by hanging them together; for hand-held packing machines, steel belts were manually threaded and then the steel belts were packed; ordinary vehicles were used to transport the packed pipe stacks. This series of processes was not only time-consuming but also had low efficiency.

[0003] Chinese Patent Application with Publication No. CN113135315A discloses an environmentally friendly sectionalized packing device for ductile iron pipes, which includes two main platform brackets.

For this environmentally friendly sectionalized packing device for ductile iron pipes, by setting the main platform bracket, the transverse driving wheels and the ductile iron pipe body, the base can be moved to the conveyor belt or transfer platform on the right side. In this way, the process of processing and packing the ductile iron pipe body can be kept standardized, the safety during the packing process can be improved, and at the same time, it can be moved in a coordinated manner through a production line. While being able to cooperate with a gantry crane for movement, the processing flexibility is improved, and the processing efficiency of the packing process is enhanced.

Detailed implementation manners

[0039] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0040] Embodiment 1

[0041] As Figures 1 to 12 shown, the packing and warehousing equipment for ductile iron pipes includes:

[0042] Sorting unit, the sorting unit includes a marking mechanism and a separation mechanism. The marking mechanism includes a marking machine 100. After the ductile iron pipes are marked by the marking machine 100, they are separated and transported through the separation mechanism;

[0043] Packing unit, the packing unit includes a stacking mechanism and a packing mechanism. The stacking mechanism is used to stack the ductile iron pipes separated by the sorting unit. The packing mechanism includes a steel strip packing machine 108. The steel strip packing machine 108 is used to pack the ductile iron pipes stacked by the stacking mechanism;

[0044] The steel strip packing machine 108 further includes a tape feeding device. The tape feeding device includes an adsorption component. The adsorption component includes an inner runner 202 and an outer runner 203. The first air duct 204 and the second air duct 205 that communicate with each other are respectively opened inside the inner runner 202 and the outer runner 203. A piston 206 is slidably installed in the second air duct 205. The piston 206 moves in the second air duct 205 to reduce the pressure in the first air duct 204, and then adsorb the steel strip through the outer runner 203.

[0045] As Figures 1 to 2As shown in the figure, in the specific implementation, the separation mechanism includes a conveying chain 101. There are multiple groups of the conveying chain 101, and one group of the conveying chain 101 is aligned with the labeling machine 100. The separation mechanism further includes a front electromagnetic crane 102, which is used to transport the ductile iron pipes to different conveying chains 101. A centering machine 103 and a turning machine 104 are also arranged at the bottom of the conveying chain 101. In this setting, multiple groups of conveying chains 101 are used to transport ductile iron pipes with different requirements. The ductile iron pipes separated by the front electromagnetic crane 102 can move to different places under the action of the conveying chain 101. The central parts of the centering machine 103 and the turning machine 104 are on the same straight line in the conveying direction of the ductile iron pipes, so that the ductile iron pipes can still be aligned after being turned around by the turning machine 104.

[0046] As Figures 1 to 2 shown, further, the palletizing mechanism includes a palletizing elevator 106. A wooden strip placing machine 107 is arranged on one side of the palletizing elevator 106, which is used to place wooden strips on ductile iron pipes at different layers. A rear electromagnetic crane 105 is also arranged on one side of the palletizing elevator 106. The rear electromagnetic crane 105 is aligned with the conveying chain 101 and is used to load the ductile iron pipes conveyed by the conveying chain 101 onto the palletizing elevator 106.

[0047] The packing mechanism further includes a palletizing conveyor 109 and a transport vehicle 110. The palletizing conveyor 109 is used to transport the ductile iron pipes packed by the steel belt packing machine 108 onto the transport vehicle 110.

[0048] In this setting, the palletizing elevator 106 descends a certain distance after loading each layer of ductile iron pipes, and then the wooden strip placing machine 107 places the wooden strips to facilitate the placement of ductile iron pipes again. The distance that the palletizing elevator 106 descends each time is adapted to the sum of the outer diameter of the ductile iron pipe and the thickness of the single-layer wooden strip.

[0049] The implementation principle of the packing and warehousing equipment for ductile iron pipes in this embodiment is as follows: The ductile iron pipes are transported to the labeling machine 100 through the conveying chain 101. During this process, the ductile iron pipes are detected for their pipe diameters by the pipe diameter detection equipment, and the pipe diameter information is sent to the labeling machine 100 and the front electromagnetic crane 102 according to the process requirements. The labeling machine 100 performs the labeling work on the ductile iron pipes. After the labeling is completed, the ductile iron pipes continue to move to the front electromagnetic crane 102 under the transportation of the conveying chain 101. The front electromagnetic crane 102 lifts away the ductile iron pipes that need to be separated according to the received information, and the ductile iron pipes that do not need to be separated continue to move on the conveying chain 101. When moving to the centering machine 103, the centering machine 103 places the ductile iron pipes in the middle position. When moving to the turning machine 104, the turning machine 104 turns around the spaced ductile iron pipes so that the directions of adjacent two ductile iron pipes are opposite.

[0050] The ductile iron pipes continue to be transported under the action of the conveying chain 101. When they are transported to the rear electromagnetic crane 105, the rear electromagnetic crane 105 lifts the ductile iron pipes onto the stacking elevator 106 for multi-layer arrangement. At the same time, the wooden strip placer 107 pads wooden strips between the ductile iron pipes on different layers to increase the buffer interval. After the arrangement is completed, the ductile iron pipes move to the steel belt packing machine 108 under the action of the stacking elevator 106. After the steel belt packing machine 108 packs them, they are transported to the transport vehicle 110 by the stacking transport machine 109.

[0051] Embodiment 2

[0052] As Figures 9 to 10 shown, in the specific implementation, the belt feeding device further includes a support assembly. The support assembly includes a fixing ring 210. One end of the fixing ring 210 is fixedly installed with a fixing pipe 212. A support ring 214 is movably sleeved outside the fixing pipe 212. The support ring 214 is fixedly installed inside the inner runner 202. A rotating shaft 216 is rotatably installed on the inner wall of the fixing pipe 212. A first gear 213 is fixedly installed on the rotating shaft 216. An internal tooth ring 215 is formed on the inner wall of the support ring 214. The internal tooth ring 215 meshes with the first gear 213. In this setting, there are two fixing rings 210 located on both sides of the outer runner 203, and the two outer runners 203 are connected to the same fixing pipe 212. When the first gear 213 rotates, it drives the inner runner 202 and the outer runner 203 to rotate through meshing with the internal tooth ring 215. A groove is formed on the side of the fixing pipe 212 so that the first gear 213 meshes with the internal tooth ring 215 through the groove.

[0053] As Figures 7 to 9 shown, further, guiding components are arranged at both ends of the support assembly. The guiding components include guiding grooves 211 formed on the side of the fixing ring 210. The guiding components further include a push rod 207 fixedly connected to the piston 206. A convex block 208 is fixedly installed on one side of the push rod 207. The convex block 208 is movably connected in the guiding groove 211. When the convex block 208 moves along the guiding groove 211, it drives the piston 206 to move through the push rod 207. A backing plate 209 is movably sleeved outside the push rod 207. The backing plate 209 is fixedly connected to the inner runner 202. In this setting, the guiding grooves 211 are arranged on the outside of the fixing ring 210, and a section of the bottom of the guiding groove 211 is convexly arranged so that the convex block 208 moves along the convexity when rotating to the bottom.

[0054] As Figure 6As shown in the figure, further, tightening components are also provided at both ends of the support component. The tightening component includes a fixing rod 218 fixedly installed on the inner wall of the fixing ring 210. A toothed plate 221 is movably sleeved on the fixing rod 218. A first spring 220 is also movably sleeved on the fixing rod 218. The tightening component further includes a second gear 217 fixedly installed on the rotating shaft 216. The second gear 217 cooperates with the toothed plate 221. The elastic force of the first spring 220 acts on the toothed plate 221 to apply a rotational force to the second gear 217. A fixing block 219 is fixedly installed at the end of the fixing rod 218. The fixing block 219 is fixedly connected to the fixing ring 210. In this setting, the elastic force of the first spring 220 acts on the toothed plate 221 to cause the toothed plate 221 to descend. The toothed plate 221 applies a thrust force to the second gear 217 to make it receive an external force for reverse rotation, thereby driving the outer runner 203 to reverse rotate to tighten the steel belt.

[0055] As Figures 4 to 5 shown in the figure, further, the belt feeding device further includes a cleaning component. The cleaning component includes a support frame 227. A brush 228 is rotatably connected to the support frame 227. A second bevel gear 226 is installed at one end of the brush 228. A first bevel gear 225 is meshed and connected to one side of the second bevel gear 226. A connecting shaft is fixedly inserted on the first bevel gear 225, and the connecting shaft is movably connected to the support frame 227. A transmission chain 223 and a transmission wheel 224 are installed between the connecting shaft and the rotating shaft 216. In this setting, when the rotating shaft 216 rotates, it drives the connecting shaft to rotate through the transmission chain 223 and the transmission wheel 224, and drives the brush 228 to rotate through the first bevel gear 225 and the second bevel gear 226 to clean foreign objects on the steel belt.

[0056] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 11 shown in the figure, further, the belt feeding device further includes an installation shell 200. A steel coil 201 is installed on the installation shell 200. The steel coil 201 bypasses the outer runner 203 and is connected to the steel belt packing machine 108. Both the support frame 227 and the side connecting plate 222 are fixedly connected to the installation shell 200. The rotating shaft 216 movably penetrates through the installation shell 200 and is fixedly installed with a rotating plate 229. A pressing plate 230 rotatably connected to the installation shell 200 is arranged on one side of the rotating plate 229. A torsion spring 231 is installed between the pressing plate 230 and the installation shell 200. The pressing plate 230 fits the rotating plate 229 under the torsion force of the torsion spring 231. In this setting, when the rotating plate 229 rotates in different directions and cooperates with the pressing plate 230, the pressure of the pressing plate 230 on the rotating plate 229 is different, so that the resistance it receives during rotation is different.

[0057] As Figures 11 to 12As shown in the figure, further, a supporting component is provided at the bottom of the installation shell 200. The supporting component includes a cushion block 239 fixedly installed at the bottom of the installation shell 200. A roller 240 and a pallet 242 are rotatably installed inside the cushion block 239. A conveyor belt 241 is movably connected to the outside of the roller 240 and the pallet 242. A guiding block 243 is fixedly installed at the bottom of the pallet 242. A retaining rod 244 is provided at the bottom of the guiding block 243. Both ends of the retaining rod 244 movably penetrate through the cushion block 239 and extend to the outside. Fixed plates 236 are fixedly installed on both sides of the cushion block 239. Telescopic rods 237 are installed at both ends of the fixed plates 236, and the other ends of the telescopic rods 237 are fixedly connected to the retaining rod 244. A second spring 238 is movably sleeved on the telescopic rod 237. Pulling ropes 234 are fixedly connected to both ends of the retaining rod 244. A fourth gear 233 and a roller 235 are rotatably installed on both sides of the installation shell 200. The pulling rope 234 bypasses the roller 235 and is fixedly connected to the fourth gear 233. A third gear 232 is fixedly installed on one side of the rotating plate 229. The third gear 232 cooperates with the fourth gear 233. In this setting, only part of the periphery of the fourth gear 233 is provided with tooth grooves, so that when the third gear 232 drives the fourth gear 233 to rotate through meshing, the fourth gear 233 automatically disengages from the third gear 232 after rotating a certain angle.

[0058] The implementation principle of the ductile iron pipe packing and warehousing equipment in this embodiment is as follows: When the steel strip packing machine 108 packs, the steel strip moves under the pulling action of the steel strip packing machine 108 and drives the outer runner 203 and the inner runner 202 to rotate under the action of friction. When the inner runner 202 rotates, it drives the backing plate 209 to rotate, so that the push rod 207 rotates accordingly. The convex block 208 on the push rod 207 slides in the guiding groove 211 and, when rotating to the bottom, moves along its own axis direction. During the movement process, it drives the piston 206 to move. The piston 206 generates negative pressure in the second air passage 205 and the first air passage 204, so as to adsorb the outer runner 203 and the steel strip, increasing the friction between the steel strip and the outer runner 203.

[0059] When the inner runner 202 rotates, it drives the support ring 214 to rotate. The support ring 214 drives the internal gear ring 215 to rotate. The internal gear ring 215 drives the first gear 213 to rotate through meshing. The first gear 213 drives the rotating shaft 216 to rotate. When the second gear 217 rotates, it toggles the tooth plate 221 to move upward. When the steel strip packing machine 108 stops pulling the steel strip, the second gear 217 no longer rotates. At this time, the elastic force of the first spring 220 acts on the tooth plate 221, so that the tooth plate 221 descends. The tooth plate 221 exerts a thrust on the second gear 217, so that the second gear 217 is subjected to an external force in the reverse direction, and then drives the outer runner 203 to reverse, so as to tighten the steel strip.

[0060] When the rotating shaft 216 rotates, it drives the connecting shaft to rotate through the transmission chain 223 and the transmission wheel 224, and drives the brush 228 to rotate through the first bevel gear 225 and the second bevel gear 226 to clean foreign matters on the steel strip.

[0061] When the steel strip packing machine 108 is packing, the rotating plate 229 rotates under the action of the rotating shaft 216, and during the rotation, the pressing plate 230 is further pressed against the rotating plate 229 through frictional contact to increase the frictional force. At this time, the steel strip packing machine 108 applies a greater pulling force when pulling the steel strip to tension the steel strip. When the rotating plate 229 rotates in the reverse direction, the fitting strength between the pressing plate 230 and the rotating plate 229 is reduced under the action of frictional contact with the rotating plate 229, so that the rotating plate 229 is easier to rotate, thereby preventing the large resistance from making it difficult for the elastic force of the first spring 220 to act on the second gear 217 to reverse the outer rotating wheel 203.

[0062] When the steel strip packing machine 108 is packing, the rotation direction of the rotating plate 229 at this time drives the third gear 232 to rotate, and drives the fourth gear 233 to rotate through meshing until the tooth section of the fourth gear 233 is separated from the third gear 232, that is, the third gear 232 and the fourth gear 233 are no longer meshed. At this time, the fourth gear 233 cannot be reset. During the rotation of the fourth gear 233, it pulls the two side stop rods 244 closer through the pull rope 234. During the process of the stop rods 244 approaching, it drives the guide block 243 to move, so that the support plate 242 is lifted, and thus the steel strip is further clamped under the extrusion action with the outer rotating wheel 203. When the rotating plate 229 rotates in the reverse direction, it drives the fourth gear 233 to rotate in the reverse direction through the third gear 232, so that the fourth gear 233 drives the pull rope 234 to slacken. At this time, the elastic force of the second spring 238 drives the guide block 243 to disengage from the stop rod 244, and the support plate 242 loosens downward to reduce the pressure between it and the outer rotating wheel 203, so that the elastic force of the first spring 220 can drive the outer rotating wheel 203 to rotate in the reverse direction.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
