Description

Technical Field

[0001] The invention belongs to the technical field of ductile iron pipe packaging, and in particular relates to packaging and warehousing equipment for ductile iron pipes. Background Art

[0002] In the past, the intelligent spray-labeling, packaging and warehousing process for small-diameter centrifugally cast ductile iron pipes was done manually. For example, workers would spray the labels manually using a template; no QR codes were sprayed. For stacking, technicians would use a crane to manually lift the pipes together for stacking. Hand-held balers were used to manually thread steel straps, which were then packaged. Ordinary vehicles were used to transport the packaged pipe stacks. This series of processes was not only time-consuming but also inefficient.

[0003] A Chinese patent application with publication number CN113135315A discloses an environmentally friendly ductile iron pipe coding and packaging device, comprising two main platform supports, above which the same ductile iron pipe body is disposed, a splicing frame being disposed on the left side of the main platform supports, and a baling machine being disposed on the sides of the two main platform supports facing away from each other, and a base being disposed above the splicing frame and the main platform supports. This environmentally friendly ductile iron pipe coding and packaging device, by disposing the main platform supports, transverse drive wheels and the ductile iron pipe body, can move its base to the conveyor belt or transfer platform on the right side. This method can maintain standardized processing and processing during the processing and packaging of the ductile iron pipe body, thereby improving safety during the packaging process, and can also be moved in coordination with an assembly line, thereby improving processing flexibility while being able to move in coordination with a gantry crane, and improving the processing efficiency of the packaging process.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0040] Example 1

[0041] like Figures 1 to 12 As shown in the figure, the packaging and storage equipment for ductile iron pipes includes:

[0042] The sorting unit includes a marking mechanism and a separation mechanism. The marking mechanism includes a marking machine 100. The marking machine 100 marks the ductile iron pipes and then separates and transports them through the separation mechanism.

[0043] The packaging unit includes a stacking mechanism and a packaging mechanism. The stacking mechanism is used to stack the ductile iron pipes separated by the sorting unit. The packaging mechanism includes a steel belt packaging machine 108. The steel belt packaging machine 108 is used to pack the ductile iron pipes after being stacked by the stacking mechanism.

[0044] The steel strapping machine 108 also includes a strap feeding device, which includes an adsorption component. The adsorption component includes an inner rotary wheel 202 and an outer rotary wheel 203. The inner rotary wheel 202 and the outer rotary wheel 203 are respectively provided with a first air channel 204 and a second air channel 205 that are interconnected. A piston 206 is slidably installed in the second air channel 205. The piston 206 moves in the second air channel 205 to reduce the pressure in the first air channel 204, thereby adsorbing the steel strap through the outer rotary wheel 203.

[0045] like Figures 1 to 2As shown, in a specific embodiment, the separation mechanism includes a conveyor chain 101, which is provided with multiple groups, and one group of the conveyor chains 101 is aligned with the marking machine 100. The separation mechanism also includes a front electromagnetic crane 102, which is used to transport the ductile iron pipes to different conveyor chains 101. The bottom of the conveyor chain 101 is also provided with a centering machine 103 and a turning machine 104. In this configuration, multiple groups of conveyor chains 101 are used to transport ductile iron pipes with different requirements. The ductile iron pipes separated by the front electromagnetic crane 102 can be moved to different places under the action of the conveyor chain 101. The center parts of the centering machine 103 and the turning machine 104 are in the same straight line in the conveying direction of the ductile iron pipes, so that the ductile iron pipes can remain aligned after turning around by the turning machine 104.

[0046] like Figures 1 to 2 As shown, further, the stacking mechanism includes a stacking elevator 106, a wood strip placement machine 107 is provided on one side of the stacking elevator 106, and the wood strip placement machine 107 is used to place wood strips on different layers of ductile iron pipes. A rear electromagnetic crane 105 is also provided on one side of the stacking elevator 106. The rear electromagnetic crane 105 is aligned with the conveyor chain 101 and is used to load the ductile iron pipes conveyed by the conveyor chain 101 onto the stacking elevator 106;

[0047] The packaging mechanism further includes a stacking conveyor 109 and a transport vehicle 110 . The stacking conveyor 109 is used to transport the ductile iron pipes packaged by the steel belt baler 108 to the transport vehicle 110 .

[0048] In this arrangement, the stacking elevator 106 descends a certain distance after each layer of ductile iron pipe is installed, and then the wood strip placement machine 107 places wood strips so that the ductile iron pipe can be placed again. The distance that the stacking 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 of wood strips.

[0049] The implementation principle of the packaging and warehousing equipment for ductile iron pipes of this embodiment is as follows: the ductile iron pipes are transported to the marking machine 100 through the conveyor chain 101. During this process, the diameter of the ductile iron pipes is detected by the pipe diameter detection equipment, and the pipe diameter information is sent to the marking machine 100 and the front electromagnetic crane 102 according to the process requirements. The marking machine 100 performs marking on the ductile iron pipes. After the marking is completed, the ductile iron pipes continue to move to the front electromagnetic crane 102 under the transportation of the conveyor chain 101. The front electromagnetic crane 102 lifts 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 conveyor 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 the ductile iron pipes arranged at intervals so that the directions of the two adjacent ductile iron pipes are opposite.

[0050] The ductile iron pipes continue to be transported under the action of the conveyor chain 101, and when they are transported to the rear electromagnetic crane 105, they are lifted onto the stacking elevator 106 by the rear electromagnetic crane 105 for multi-layer arrangement. At the same time, the wooden strip placement machine 107 pads wooden strips between the ductile iron pipes of different layers to increase the buffer interval. After the arrangement is completed, the ductile iron pipes are moved to the steel belt baler 108 under the action of the stacking elevator 106. After the steel belt baler 108 packs them, it is transported to the transport vehicle 110 via the stacking conveyor 109.

[0051] Example 2

[0052] like Figures 9 and 10 As shown, in a specific embodiment, the tape feed device further includes a support assembly, which includes a fixed ring 210, a fixed tube 212 fixedly mounted on one end of the fixed ring 210, a support ring 214 movably sleeved on the outer side of the fixed tube 212, and a fixedly mounted inside the inner rotating wheel 202. A rotating shaft 216 is rotatably mounted on the inner wall of the fixed tube 212, and a first gear 213 is fixedly mounted on the rotating shaft 216. The inner wall of the support ring 214 is provided with an inner gear ring 215, which meshes with the first gear 213. In this configuration, two fixed rings 210 are provided and located on both sides of the outer rotating wheel 203, and the two outer rotating wheels 203 are connected to the same fixed tube 212. When the first gear 213 rotates, it meshes with the inner gear ring 215 to drive the inner rotating wheel 202 and the outer rotating wheel 203 to rotate. A groove is provided on the side of the fixed tube 212 to allow the first gear 213 to mesh with the inner gear ring 215 through the groove.

[0053] like Figures 7 to 9 As shown, further, guide assemblies are provided at both ends of the support assembly, and the guide assemblies include guide grooves 211, which are provided on the side of the fixed ring 210. The guide assembly also includes a push rod 207, which is fixedly connected to the piston 206. A protrusion 208 is fixedly mounted on one side of the push rod 207, and the protrusion 208 is movably connected within the guide groove 211. When the protrusion 208 moves along the guide groove 211, it drives the piston 206 to move through the push rod 207. A pad 209 is movably sleeved on the outer side of the push rod 207, and the pad 209 is fixedly connected to the inner rotating wheel 202. In this configuration, the guide groove 211 is arranged on the outer side of the fixed ring 210, and a section of the bottom of the guide groove 211 is provided as a protrusion, so that the protrusion 208 moves along the protrusion when it rotates to the bottom.

[0054] like Figure 6As shown, further, a tightening assembly is provided at both ends of the support assembly, and the tightening assembly includes a fixed rod 218 fixedly mounted on the inner wall of the fixing ring 210, a toothed plate 221 movably sleeved on the fixed rod 218, and a first spring 220 movably sleeved on the fixed rod 218. The tightening assembly also includes a second gear 217 fixedly mounted on the rotating shaft 216, the second gear 217 and the toothed plate 221 cooperate with each other, and 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 mounted at the end of the fixed rod 218, and the fixing block 219 is fixedly connected to the fixing ring 210. In this configuration, the elastic force of the first spring 220 acts on the toothed plate 221 to cause the toothed plate 221 to descend, and the toothed plate 221 applies a thrust to the second gear 217, causing it to be subjected to a reverse external force, thereby driving the outer rotating wheel 203 to reverse, thereby tightening the steel belt.

[0055] like Figures 4 and 5 As shown, further, the belt feeding device also includes a cleaning assembly, which includes a support frame 227, a brush 228 rotatably connected to the support frame 227, a second bevel gear 226 mounted on one end of the brush 228, a first bevel gear 225 meshingly connected to one side of the second bevel gear 226, a connecting shaft fixedly plugged into the first bevel gear 225, and the connecting shaft is movably connected to the support frame 227, and a transmission chain 223 and a transmission wheel 224 are installed between the connecting shaft and the rotating shaft 216. In this arrangement, when the rotating shaft 216 rotates, the connecting shaft is driven to rotate by the transmission chain 223 and the transmission wheel 224, and the brush 228 is driven to rotate by the first bevel gear 225 and the second bevel gear 226 to clean foreign matter from the steel belt.

[0056] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 11 As shown, the tape feeding device further includes a mounting shell 200, on which a steel coil 201 is mounted. The steel coil 201 passes around an outer rotating wheel 203 and is connected to the steel strapping machine 108. The support frame 227 and the side connecting plate 222 are both fixedly connected to the mounting shell 200. The rotating shaft 216 movably passes through the mounting shell 200 and is fixedly mounted with a rotating plate 229. A pressure plate 230 rotatably connected to the mounting shell 200 is provided on one side of the rotating plate 229. A torsion spring 231 is installed between the pressure plate 230 and the mounting shell 200. The pressure plate 230 is pressed against the rotating plate 229 under the torsion of the torsion spring 231. In this configuration, when the rotating plate 229 rotates in different directions and cooperates with the pressure plate 230, the pressure of the pressure plate 230 on the rotating plate 229 is different, so that the resistance to its rotation is different.

[0057] like Figures 11 to 12As shown, further, a supporting assembly is provided at the bottom of the mounting shell 200, and the supporting assembly includes a pad 239 fixedly mounted on the bottom of the mounting shell 200, a roller 240 and a support plate 242 are rotatably mounted inside the pad 239, and a conveyor belt 241 is movably connected to the roller 240 and the outer side of the support plate 242, and a guide block 243 is fixedly mounted on the bottom of the support plate 242, and a stopper 244 is provided at the bottom of the guide block 243, and both ends of the stopper 244 movably penetrate the pad 239 and extend to the outside, and fixed rods are fixedly mounted on both sides of the pad 239. The fixed plate 236 has telescopic rods 237 mounted on both ends of the fixed plate 236. The other end of the telescopic rod 237 is fixedly connected to the blocking rod 244. A second spring 238 is movably sleeved on the telescopic rod 237. The blocking rod 244 has a pull rope 234 fixedly connected to both ends. A fourth gear 233 and a roller 235 are rotatably mounted on both sides of the mounting housing 200. The pull rope 234 passes through the roller 235 and is fixedly connected to the fourth gear 233. A third gear 232 is fixedly mounted on one side of the rotating plate 229. The third gear 232 and the fourth gear 233 interact with each other. In this configuration, the fourth gear 233 is only partially provided with teeth and grooves around its perimeter. This ensures that when the third gear 232 engages and drives the fourth gear 233 to rotate, the fourth gear 233 automatically disengages from the third gear 232 after rotating a certain angle.

[0058] The implementation principle of the packaging and warehousing equipment for ductile iron pipes of this embodiment is as follows: when the steel belt baler 108 is packaging, the steel belt moves under the pulling action of the steel belt baler 108, and drives the outer rotating wheel 203 and the inner rotating wheel 202 to rotate under the action of friction. When the inner rotating wheel 202 rotates, it drives the pad 209 to rotate, so that the push rod 207 rotates accordingly. The protrusion 208 on the push rod 207 slides in the guide groove 211, and when it rotates to the bottom, it moves along its own axis direction, and in the process of moving, it drives the piston 206 to move. The piston 206 generates negative pressure in the second air channel 205 and the first air channel 204, so that the outer rotating wheel 203 is adsorbed on the steel belt, thereby increasing the friction between the steel belt and the outer rotating wheel 203;

[0059] When the inner rotating wheel 202 rotates, it drives the support ring 214 to rotate, and the support ring 214 drives the inner gear ring 215 to rotate. The inner gear ring 215 drives the first gear 213 to rotate through meshing, and the first gear 213 drives the rotating shaft 216 to rotate. When the second gear 217 rotates, it pushes the tooth plate 221 to move upward. When the steel strapping machine 108 stops pulling the steel strap, the second gear 217 no longer rotates. At this time, the elastic force of the first spring 220 acts on the tooth plate 221 to make the tooth plate 221 descend. The tooth plate 221 applies a thrust to the second gear 217, so that it is subjected to a reverse external force, thereby driving the outer rotating wheel 203 to reverse, so as to tighten the steel strap.

[0060] When the rotating shaft 216 rotates, the connecting shaft is driven to rotate through the transmission chain 223 and the transmission wheel 224, and the brush 228 is driven to rotate through the first bevel gear 225 and the second bevel gear 226 to clean foreign matter from the steel belt;

[0061] When the steel strapping machine 108 is strapping, the rotating plate 229 rotates under the action of the rotating shaft 216. During the rotation process, the pressing plate 230 is further pressed against the rotating plate 229 due to frictional contact with the pressing plate 230, thereby increasing friction. At this time, the steel strapping machine 108 applies greater tension when pulling the steel strap to tighten the steel strap. When the rotating plate 229 is reversed, the frictional contact between the pressing plate 230 and the rotating plate 229 reduces the contact strength between the pressing plate 230 and the rotating plate 229, making it easier for the rotating plate 229 to rotate, thereby preventing the large resistance from causing the elastic force of the first spring 220 to be difficult to act on the second gear 217 to reverse the outer rotating wheel 203.

[0062] When the steel strapping machine 108 is strapping, the rotation of the rotating plate 229 drives the third gear 232 to rotate, and drives the fourth gear 233 to rotate through meshing, until the tooth segment 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 process, the fourth gear 233 pulls the blocking rods 244 on both sides together through the pull rope 234, and the blocking rods 244 move the guide block 243 closer together during the process of moving together. The rotating plate 229 is rotated to prop up the supporting plate 242, thereby further clamping the steel belt under the squeezing action with the outer rotating wheel 203. When the rotating plate 229 is reversed, the fourth gear 233 is driven to reverse through the third gear 232, so that the fourth gear 233 drives the pull rope 234 to relax. At this time, the elastic force of the second spring 238 drives the guide block 243 to disengage from the blocking rod 244, and the supporting plate 242 is loosened downward to reduce the pressure between it and the outer rotating wheel 203, thereby enabling the elastic force of the first spring 220 to drive the outer rotating wheel 203 to reverse.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
