[0001] The present application relates to the technical field of packaging equipment, in particular to a pipe fitting automatic packaging production line. BACKGROUND

[0002] In the batch production process of tee pipes and elbow pipes, automatic packaging is a key link to improve production efficiency and guarantee product quality uniformity. In order to protect the open end face of the pipe fitting, prevent foreign matter from damaging the pipe cavity, and avoid damaging the package with the pipe end edge, the open end of the pipe fitting is capped during automatic packaging.

[0003] The capping mechanism on the traditional pipe fitting packaging production line is composed of a sliding table, a material receiving table and a feeding structure. When the pipe fitting passes through the capping station, the feeding mechanism supplies the end cap to the material receiving table, and then the sliding table moves the material receiving table to make the end cap be capped on the end of the pipe fitting. However, in order to consider the production efficiency, burrs generated during pipe fitting cutting cannot be completely removed. When the pipe fitting is capped and packaged, the burrs will contact the mating surface of the end cap, causing the end cap to be stuck during capping. At this time, the capping method of rigid pushing will greatly increase the pressure on the end cap, thereby easily causing the end cap to crack and be damaged. Moreover, the edge of the end cap made of plastic material will inevitably be deformed by external force, making it impossible for the end cap to match the opening of the pipe fitting during capping.

[0015] As a further description of the above-mentioned technology, a motor two for driving the rotation of the positioning seat is fixed on the rack cabinet.

[0018] 1. When burrs exist in the pipe opening, the spring buffer can reduce the pressure degree of the end cover, prevent the end cover from cracking and damaging, and the buffering effect of the spring can also speed up the buckling speed and improve the overall pipe fitting packaging efficiency; in addition, when the burrs cause the end cover to be stuck, the buckling box drives the slider and the embedded plate to continue to move, at this time the spring is compressed, the inner cylinder gradually penetrates into the sleeve, after the protrusion slides from the straight section of the sliding groove to the spiral section of the sliding groove, under the cooperation of the protrusion and the sliding groove, the inner cylinder drives the embedded plate, the clamping jaw and the end cover to deflect, so that the end cover and the pipe body contact surface slide circumferentially, the burrs are removed or avoided by using the shearing force, and the buckling jam caused by the burrs during the pipe fitting packaging buckling is solved, thereby reducing the damage rate of the end cover and saving production cost while improving the packaging efficiency.

[0019] 2. The motor three drives the connecting rod and the push piece to rotate, so that the push piece positions the end cover to avoid deviation of the end cover during buckling, and when deformation exists on the edge of the end cover and causes the end cover to be unable to match the pipe opening, the pipe opening is in contact with the push piece, and when the edge of the end cover is blocked by the pipe and cannot be buckled, the end cover deflects under the action of the rotating assembly, the end cover and the push piece rotate relatively, and the push piece props open the recessed part of the edge of the end cover, so that the end cover restores the deformation and is sleeved on the pipe opening. This design solves the problem that the end cover with edge deformation cannot be buckled, effectively improves the buckling qualified rate, and ensures the continuous operation of the production line.

[0020] 3. During buckling, the push piece can deflect and abut against the pipe under the elastic force of the torsional spring to position the pipe opening, and by positioning the pipe and the end cover respectively, the alignment accuracy of the pipe and the end cover can be effectively improved, and the buckling success rate can be improved. Moreover, when the end cover cracks and is damaged after buckling, the motor three drives the connecting rod and the push piece to deflect towards the end cover, the push piece deflects relatively with the connecting rod after contacting the pipe body, the end of the push piece slides on the surface of the pipe body, and is inserted between the pipe body and the end cover. This design can pry up the end cover, so as to facilitate the removal and replacement of the damaged end cover. BRIEF DESCRIPTION OF DRAWINGS

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0041] As shown in Figures 1-13 , the present application provides a pipe automatic packaging production line, which sequentially comprises a material detection station 11, a laser marking station 12, an automatic cover station 20, an automatic bagging station 13 and a labeling station 14. A speed chain is arranged between the material detection station 11 and the automatic cover station 20. The pipe is driven by the speed chain to sequentially pass through the material detection station 11, the laser marking station 12 and the automatic cover station 20, so as to perform screening, laser marking and cover operation, realize automatic processing of the pipe, and prepare for subsequent packaging.

[0042] Referring to Figures 2-6 , the automatic cover station 20 comprises a rack electric cabinet 21. A four-axis mechanical arm 22 is fixedly installed on the rack electric cabinet 21. A positioning seat 29 is rotationally connected to the rack electric cabinet 21 and a motor two 210 for driving the positioning seat 29 to rotate is fixedly installed on the rack electric cabinet 21. The positioning seat 29 is provided with a placing groove matched with the pipe and the depth of the groove is greater than the radius of the pipe, so that the pipe remains stable when the cover is stressed. A sliding table 23 is arranged on the rack electric cabinet 21. A cover box 25 is installed on the sliding table 23. The sliding table 23 drives the cover box 25 to move linearly to cover. A sliding block 26 is slidably connected in the cover box 25. An inlaid plate 27 is rotationally connected to one side of the sliding block 26. A clamping unit 30 is arranged on the inlaid plate 27.

[0043] Referring to Figure 7 and Figure 8 , in order to avoid the burr in the opening of the pipe not being removed clean, causing the cover to be stuck and the end cover to be damaged by excessive pressure, a rotating assembly 28 is arranged in the cover box 25. The rotating assembly 28 comprises a spring 281 arranged between the sliding block 26 and the cover box 25. An inner cylinder 282 penetrating through the sliding block 26 is fixed to one side of the inlaid plate 27 close to the inside of the cover box 25. A sleeve 283 sleeved on the outside of the inner cylinder 282 is fixed to the inner wall of the cover box 25. The inner wall of the sleeve 283 is fixed with a protrusion 284 embedded in the sliding groove of the inner cylinder 282.

[0044] When the pipe is conveyed to the automatic capping station 20 by the speed-up chain, the pipe is taken off the speed-up chain by the mechanical arm 22 and placed in the positioning seat 29, with the opening of the pipe facing the capping box 25, the end cap to be capped is fixed with the inner plate 27 by the clamping unit 30, then the capping box 25 is driven to move close to the pipe by the sliding table 23, the end cap is moved by the sliding block 26 and the inner plate 27 until the end cap contacts and caps the pipe, realizing automatic capping.

[0045] When the spring 281 is not compressed, the protrusion 284 is in the straight section sliding groove, when the opening of the pipe has residual burrs, the resistance of capping increases, at this time, the movement of the inner plate 27 and the sliding block 26 is blocked, the sliding block 26 moves relative to the capping box 25, and the spring 281 is compressed, the elastic force of the spring 281 can buffer during capping, avoiding the end cap from being damaged by rigid pushing and cracking, ensuring that the end cap is intact after capping, and under the buffering effect of the spring 281, the moving speed of the sliding table 23 during capping can be accelerated, thereby improving the capping efficiency;

[0046] When the burrs are sharp and protruding, causing the capping to be stuck, the end cap is limited to move, so that the inner plate 27 and the sliding block 26 cannot continue to move forward, at this time, the sliding table 23 continues to drive the capping box 25 to move, the spring 281 is gradually compressed, the inner cylinder 282 gradually penetrates into the sleeve 283, the protrusion 284 slides in the straight section sliding groove, as the inner cylinder 282 continues to penetrate into the sleeve 283, the protrusion 284 enters the spiral section sliding groove, under the cooperation of the protrusion 284 and the sliding groove, the inner cylinder 282 penetrates into the sleeve 283 while being deflected, driving the inner plate 27 to deflect, thereby driving the end cap to rotate by the clamping unit 30, so that the end cap and the pipe contact surface slide circumferentially, the burrs are cut off or avoided by using the shearing force, the end cap is unblocked, and the capping is continued. This design avoids the capping being stuck due to the burrs, reduces the pressure borne by the end cap during capping, realizes smooth capping, and ensures that the end cap is intact.

[0047] Referring to Figure 9 and Figure 10 , the clamping unit 30 includes two clamping jaws 31 symmetrically connected to one side of the inner plate 27, a tension spring 32 is fixed between the clamping jaw 31 and the inner plate 27, and a roller 33 is rotatably connected to the opposite side of each clamping jaw 31. When the end cap is clamped by the two clamping jaws 31, the tension spring 32 is in a stretched state, and under the elastic force of the tension spring 32, the roller 33 is tightly attached to the end cap. When the inner plate 27 rotates, it drives the clamping jaw 31 and the roller 33 to rotate, and through the friction force between the roller 33 and the end cap, the end cap is driven to rotate to eliminate the capping blockage.

[0048] Referring to Figure 4 and Figure 5The feeding assembly 50 is arranged on the rack cabinet 21, and includes a hopper 51 and a cylinder 52. The hopper 51 is used for storing end covers, and is provided with a hopper opening at the bottom for gravity feeding. The cylinder 52 is arranged at the bottom of the hopper 51. The hopper 51, the cylinder 52, the sliding table 23 and the cover box 25 are arranged in a straight line. When the cylinder 52 is extended, the end cover leaked from the hopper 51 is pushed to the embedded plate 27 to realize automatic feeding of the cover.

[0049] The sliding table 23 includes a limiting frame 231 fixed to the rack cabinet 21 and a motor 232. The limiting frame 231 is internally connected with a bearing block 234 in a sliding mode. The limiting frame 231 is internally connected with a lead screw 233 in a rotating mode. The lead screw 233 penetrates through the bearing block 234 and is connected with the bearing block 234 in a sliding mode. The output shaft of the motor 232 is fixed to the lead screw 233. When the motor 232 drives the lead screw 233 to rotate, the bearing block 234 is driven to slide in the limiting frame 231, so that the cover box 25, the sliding block 26 and the embedded plate 27 are moved between the feeding assembly 50 and the pipe fitting.

[0050] Referring to Figure 5 and Figure 6 , in order to connect the feeding with the cover closing and realize automatic cover closing, the turnover structure 24 is arranged. The turnover structure 24 includes a shaft 241 rotatably connected to the top of the bearing block 234 and fixed to the cover box 25. The shaft 241 is fixed with two push plates 242 at an angle of 90 degrees. The top of the limiting frame 231 is fixed with a blocking block 243. The blocking block 243 is located between the two push plates 242 and is in the same plane with the two push plates 242.

[0051] As shown in Figure 5 and Figure 6 , the embedded plate 27 has been fixed with the end cover through the clamping unit 30. The bearing block 234 continues to move towards the direction of the positioning seat 29 to close the cover. After single cover closing, the bearing block 234 drives the shaft 241, the cover box 25, the sliding block 26, the embedded plate 27 and the clamping jaw 31 to move reversely. At this time, the roller 33 reduces the friction between the clamping jaw 31 and the end cover to avoid the end cover from falling off. After the bearing block 234 moves to the position shown in Figure 5 and Figure 6 , the bearing block 234 continues to move away from the positioning seat 29. At this time, the vertical push plate 242 is blocked by the blocking block 243 to turn over, driving the shaft 241 and the cover box 25 to turn over by 90 degrees. The shaft 241 passes through the blocking block 243, and the other push plate 242 becomes vertical. The turning over of the cover box 25 makes the embedded plate 27 face upwards. The feeding position of the end cover on the embedded plate 27 is flush with the discharging position of the hopper 51 at the bottom.

[0052] The material box 51 extends to push the end cover, the end cover pushes away the two clamping jaws 31 and enters between the two clamping jaws 31, then the two clamping jaws 31 are reset under the elastic force of the tension spring 32 to clamp the end cover, the control motor 232 drives the lead screw 233 to rotate reversely, drives the bearing block 234 to move towards the positioning seat 29 again, drives the cover box 25, the sliding block 26 and the embedded plate 27 to cover, in the process, the vertical push plate 242 is blocked by the blocking block 243, drives the shaft rod 241 and the cover box 25 to overturn, makes the embedded plate 27 face the positioning seat 29, the embedded plate 27 continues to move towards the pipe and drives the end cover to be buckled on the pipe end, realizes automatic covering.

[0053] By driving the positioning seat 29 to rotate by the motor 210, the openings of the tee pipe or the elbow pipe can be sequentially oriented to the embedded plate 27, and the openings are sequentially covered. After all the openings of the pipe are covered, the pipe is grabbed and placed on the conveying belt of the automatic bagging station 13 by the mechanical arm 22 for packaging.

[0054] The cover box 25 and the bearing block 234 are both fixed with magnetic stickers 244, the magnetic force between the magnetic stickers 244 can stably connect the cover box 25 with the bearing block 234 after the cover box 25 is turned over, avoiding the cover box 25 from shaking under inertia and other external forces during operation, causing the end cover to fall off.

[0055] Referring to Figures 10-13 , based on the above design, considering that the end cover is mostly made of plastic material, the opening edge is easy to deform and cause the end cover to be unable to be covered, the clamping jaw 31 is provided with an auxiliary mechanism 40, the auxiliary mechanism 40 includes two side jaws 41 fixed on the sliding block 26, the two side jaws 41 are symmetrically arranged and aligned with the two clamping jaws 31 respectively, avoiding blocking the end cover from entering between the two clamping jaws 31, the side jaw 41 is fixedly provided with a motor 42, a connecting rod 43 is fixed on the output shaft of the motor 42, and one end of the connecting rod 43 fixed with the output shaft of the motor 42 is rotationally connected with the side jaw 41, and the other end of the connecting rod 43 is rotationally connected with a push piece 44;

[0056] After the end cover enters between the two clamping jaws 31, the connecting rod 43 and the push piece 44 are driven by the motor 42 to rotate, so that the push piece 44 contacts the opening of the end cover, as shown in Figure 13 , the push piece 44 fixes the end cover at this time, preventing the end cover from falling off when the embedded plate 27 is turned over with the cover box 25, and positioning the end cover to improve the accuracy of the position of the end cover during covering.

[0057] Furthermore, when the opening of the end cover deforms, the pipe and the end cover are located as Figure 13When the end cap is deformed, the end cap cannot be buckled with the pipe opening, and the end cap will be deflected under the action of the rotating assembly 28, and the end cap will be deflected under the action of the rotating assembly 28. The relative rotation occurs between the push piece 44, at this time, under the support of the pipe, the push piece 44 can support the edge of the end cap, restore the deformation of the end cap, and make the end cap sleeve on the pipe opening. This design solves the problem that the deformed end cap cannot be buckled with the pipe opening, avoids frequent interruption of the buckling due to the deformed end cap, and ensures the automatic packaging efficiency of the pipe.

[0058] Referring to Figure 11 , a limiting unit 45 is arranged between the connecting rod 43 and the push piece 44, a limiting groove is formed in the inner wall of the connecting rod 43, the limiting unit 45 includes a limiting block 451 fixed to one side of the push piece 44 and embedded in the limiting groove, and a torsion spring 452 is arranged between the rotating connection of the connecting rod 43 and the push piece 44. Figure 13 As shown in the state, the push piece 44 cannot rotate counterclockwise, so it can clamp and fix the end cap. When the push piece 44 supports the end cap to make the end cap preliminarily sleeve on the pipe opening, the connecting rod 43 is driven by the motor three 42 to rotate counterclockwise, at this time, the push piece 44 can deflect clockwise, so that the connecting rod 43 drives the push piece 44 to pull out from between the pipe and the end cap. At the same time, during the buckling process, the push piece 44 can contact the two sides of the pipe opening under the elastic force of the torsion spring 452, so as to achieve the positioning effect of the pipe.

[0059] After the buckling is completed, the motor three 42 drives the connecting rod 43 and the push piece 44 to deflect greatly, so that the push piece 44 is staggered with the end cap, and the push piece 44 does not contact the end cap when the inner embedding plate 27 returns.

[0060] When the end cap is buckled and cracked, the motor three 42 drives the connecting rod 43 and the push piece 44 to deflect towards the end cap, the push piece 44 deflects relatively with the connecting rod 43 after contacting the pipe body, the end of the push piece 44 slides on the surface of the pipe body, and is inserted between the pipe body and the end cap. This design can pry up the end cap to facilitate the disassembly and replacement of the damaged end cap. Then, the sliding block 26 and the inner embedding plate 27 are driven by the sliding table 23 to move away from the pipe, and drive the side claw 41, the connecting rod 43 and the push piece 44 to move. The end cap is removed by the push piece 44, which facilitates the replacement of the end cap.

[0061] Working principle: in the initial state, the front of the inner embedding plate 27 is upward, and the feeding position of the end cap on the inner embedding plate 27 is flush with the bottom of the feeding position of the magazine 51.

[0062] The pipe fittings are conveyed by the speed-up chain, screened and laser marked at the material detection station 11 and the laser marking station 12, and then grabbed by the mechanical arm 22 and placed in the positioning seat 29. The cylinder 52 is elongated to push the end cap leaked out from the bottom of the material box 51, so that the end cap pushes away the two clamping jaws 31 and enters between the two clamping jaws 31. The two clamping jaws 31 clamp the end cap under the elastic force of the tension spring 32. The roller 33 is used to reduce the friction between the clamping jaw 31 and the end cap when the clamping jaw 31 returns after the cap is buckled, so as to avoid the end cap from falling off;

[0063] The motor one 232 drives the screw rod 233 to rotate and drive the bearing block 234 to move towards the direction of the pipe fitting. The bearing block 234 drives the shaft rod 241, the push plate 242, the cap buckling box 25, the sliding block 26 and the embedded plate 27 to move together. During the movement, the blocking block 243 blocks the vertical push plate 242, so that the push plate 242 drives the shaft rod 241, the cap buckling box 25, the sliding block 26 and the embedded plate 27 to overturn towards the direction of the pipe fitting. At this time, the end cap is aligned with the opening of the pipe fitting. The screw rod 233 continues to rotate, and the embedded plate 27 drives the end cap to be buckled on the opening of the pipe fitting;

[0064] When the vertical push plate 242 is blocked and overturned to be horizontal, the other push plate 242 is overturned to be vertical. When the bearing block 234 returns in the reverse direction driven by the motor one 232, the blocking block 243 blocks the vertical push plate 242 to make the cap buckling box 25 overturn and reset, so that the above operation process can be repeated to realize automatic cap buckling;

[0065] When the burr is sharp and protruding, causing the cap to be stuck, the end cap is limited to move, and the embedded plate 27 and the sliding block 26 cannot continue to move forward to the expected position during the buckling of the cap. At this time, the sliding table 23 continues to drive the cap buckling box 25 to move. The spring 281 is gradually compressed, the inner cylinder 282 gradually penetrates into the sleeve 283, the protruding block 284 slides in the straight section sliding groove, and as the inner cylinder 282 continues to penetrate into the sleeve 283, the protruding block 284 enters the spiral section sliding groove. Under the cooperation of the protruding block 284 and the sliding groove, the inner cylinder 282 penetrates into the sleeve 283 while being deflected, driving the embedded plate 27 to deflect, so as to drive the end cap to rotate through the clamping jaw 31 and the roller 33, so that the end cap and the pipe body contact surface slide circumferentially, the burr is cut off or avoided by using the shearing force, the cap is stuck, and the buckling of the cap is continued;

[0066] When the opening of the end cap is deformed, the pipe fitting and the end cap are located as shown in the figure Figure 13When the end cap is deformed, the end cap cannot be buckled with the pipe opening, the pipe blocks the end cap from moving forward, the buckle box 25 and the slider 26 continue to move, the inner plate 27 will drive the end cap to deflect under the action of the rotating assembly 28, and the end cap will rotate relative to the tab 44, the tab 44 will support the edge of the recessed end cap, restore the deformation of the end cap, and make the end cap sleeve on the pipe opening, then the motor three 42 drives the connecting rod 43 and deflects away from the end cap, the tab 44 is pulled out from the pipe and the end cap, the buckle box 25 drives the slider 26 and the inner plate 27 to move forward to realize buckling;

[0067] By rotating the positioning seat 29 through the motor two 210, the openings of the tee pipe or the elbow pipe are sequentially directed to the inner plate 27, and each opening is buckled, and after all the openings of the pipe are buckled, the pipe is grabbed and placed on the conveying belt of the automatic bagging station 13 through the mechanical arm 22 to be packaged, and finally the packaging is completed through the labeling station 14.

[0068] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can replace or change the technical pipe automatic packaging production line and the invention concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
