Detailed implementation manners

[0025] An automatic plug-pulling mechanism, as shown in Figure 1 and Figure 2 , which includes an upper machine table 10, a lifting cylinder 20, a composite adjustment table 30, a clamping suction cup assembly 40, and a plug-pulling mechanism 50;

[0026] The upper machine table 10 includes a plug-pulling positioning plate 11 and an upper convex vertical plate 12. The upper surface of the plug-pulling positioning plate 11 is provided with a material pipe positioning groove 13; the lifting cylinder 20 includes a cylinder block 21, a piston end 22, a guide track 23, and a guide rod 24; the composite adjustment table 30 includes a mounting seat body 31 and a horizontal longitudinal cylinder 32; the clamping suction cup assembly 40 includes a connecting cross plate 41 and a suction cup assembly 42 with downward protrusions at both ends; the plug-pulling mechanism 50 includes a support frame 51, a transverse driving cylinder 52, and a clamping cylinder 53;

[0027] The cylinder block 21 and the guide track 23 are fixedly installed on the upper convex vertical plate 12. The guide track 23 is arranged upward in the height direction. The piston end 22 is embedded in the guide track 23. The cylinder block 21 drives the piston end 22 to move along the height direction of the guide track 23. The piston end 22 is provided with a downwardly arranged guide rod 24. The lower end of the guide rod 24 is fixedly installed with a mounting seat body 31. The mounting seat body 31 is installed with a horizontal longitudinal cylinder 32. The piston output end of the horizontal longitudinal cylinder 32 is connected to the middle position in the length direction of the connecting cross plate 41 through a connecting mechanism 33. The suction cup assemblies 42 are respectively used for adsorbing the corresponding positions on the upper surfaces at both ends in the length direction of the material pipe 100;

[0028] One end of the positioning groove 13 of the material pipe is fixedly equipped with a support frame 51 of the plug pulling mechanism 50 through a connecting member 60. A transverse driving cylinder 52 is fixedly installed on the support frame 51. The piston end of the transverse driving cylinder 52 is fixedly equipped with a clamping cylinder 53. A pair of clamping rods 531 of the clamping cylinder 53 are used to insert into the cavity of the material pipe 100 to clamp the plunger nail and pull out the plug nail.

[0029] In a specific embodiment, see Figures 1 - 3 : A cushion block 70 is installed at the bottom of the end of the plug pulling positioning plate 11 away from the plug pulling mechanism 50, which makes the plug pulling end of the plug pulling positioning plate 11 inclined downward.

[0030] A stop structure 131 is arranged at the relatively low end of the positioning groove 13 of the material pipe, which ensures that the material pipe 100 can complete the positioning in the length direction only by gravity.

[0031] A connecting cross plate 80 is fixedly installed at the bottom of the guiding rod 24. One end in the length direction of the connecting cross plate 80 is pivotally connected with an inclined adjustment cylinder 90. The middle position in the length direction of the connecting cross plate 80 is pivotally connected with the upper part of the connecting mounting seat body 31. The piston end of the inclined adjustment cylinder 90 is pivotally connected with the side wall of the mounting seat body 31, which makes the connecting cross plate 80 adjusted from horizontal to the same slope as the plug pulling positioning plate 11 under the drive of the inclined adjustment cylinder 90.

[0032] The connecting member 60 includes a horizontal plate 61 and a vertical plate 62. The horizontal plate 61 is connected to the lower part of the corresponding end of the plug pulling positioning plate 11 and extends outward. The support frame 51 is fixedly installed on the outer vertical surface of the vertical plate 62. The transverse driving cylinder 52 is fixedly installed on the upper surface of the support frame 51.

[0033] It further includes a plug nail material box 110. The plug nail material box 110 is located directly below the horizontal plate 61. An avoidance opening 63 is arranged on the outside of the horizontal plate 61 corresponding to the plug pulling nail area. After the transverse driving cylinder 52 drives the clamping rod 531 of the clamping cylinder 53 to move outward to pull out the plug nail and reach the avoidance opening 63, the clamping cylinder 52 is loosened, so that the pulled out plug nail falls into the plug nail material box 110.

[0034] A second connecting block 120 is further arranged on the upper part of the clamping cylinder 53. An inductor 130 is arranged at the front end of the second connecting block 120. The inductor 130 is used to sense whether the material pipe is in place. After the inductor 130 senses that the material pipe is in place, the clamping cylinder 52 acts to clamp the plug nail.

[0035] The working principle is as follows. The material pipe is held by the clamping suction cup assembly at the corresponding station on the conveying line. Then, the lifting cylinder operates, placing the material pipe above the plug-pulling positioning plate, but not on the same vertical plane. Subsequently, the tilting adjustment cylinder and the horizontal longitudinal cylinder operate, positioning the material pipe directly above the material pipe positioning groove and arranging it parallel to the plug-pulling positioning plate. The lifting cylinder then operates to place the material pipe into the material pipe positioning groove. Meanwhile, the suction cup assembly releases the material pipe. The material pipe is positioned by the stop structure under the action of gravity. Then, a pair of clamping rods of the clamping cylinder are positioned on both sides of the plug of the lumen, and the clamping cylinder performs the clamping operation. Subsequently, the lateral driving cylinder drives to pull out the plug, causing the plug to separate from the material pipe. Then, the plug is placed into the plug bin. After that, the material pipe is sent back to the corresponding station on the conveying line again for subsequent feeding. It can quickly perform automatic plug-pulling after taking the material pipe out of the conveying line and then reset the material pipe, ensuring reliable docking with the feeding line and the feeding efficiency.
