The lifting device 12 can move along the transverse moving device 11. The first material picking device 121 and the second material picking device 122 can be lifted up and down. The discharging rack 2 includes a receiving seat 21. and a spreading seat 22, the material receiving seat 21 is provided with a first cross-shaped slot 211, and a slot 212 capable of accommodating a rubber ring 103 is provided on the upper end surface of the material receiving seat 21, and a cross-shaped plug plate 1211 corresponding to the first slot 211 is provided at the lower end of the first material picking device 121, and the plug plate 1211 can be inserted into the first slot 211 by lifting and lowering the lifting device 12, so that the rubber ring 103 is spread open by the plug plate 1211 and fixed on the plug plate 1211, and a chamfer is provided on the lower end edge of the plug plate 1211 to facilitate the spreading of the rubber ring 103 when it contacts the plug plate 1211.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the first material taking device 121 sends the rubber ring 103 at the material receiving seat 21 to the top of the expansion seat 22. The expansion seat 22 includes a guide sleeve 221, a socket 222, and a spring 223. The socket 222 is a cone with a diameter gradually decreasing upward. The socket 222 is provided with a second slot 2221 opening upward, and the second slot 2221 corresponds to the plug board 1211 for the plug board 1211 to be inserted. The step 12111 is located at the upper end of the plug board 1211. The diameter of the circumscribed circle formed by the step 12111 is greater than the diameter of the rubber ring 103. When the plug board 1211 with the rubber ring 103 is inserted downward into the second slot 2221, the rubber ring 103 is limited and blocked by the step 12111 at the upper end of the plug board 1211, and then the rubber ring 103 is expanded by the socket 222 and detached from the plug board 1211 to fix the socket 222 with the maximum diameter.

The spring 223 is installed inside the guide sleeve 221, and at least a part of the socket 222 is located in the guide sleeve 221. The upper end of the spring 223 abuts against the lower end of the socket 222, and the socket 222 can slide up and down along the guide sleeve 221. When the second material taking device 122 is located above the support seat 22, the second material taking device 122 descends to make the sleeve 1221 21 is sleeved and pressed downwardly against the socket 222. As the socket 222 retracts the guide sleeve 221, the rubber ring 103 on the socket 222 is sleeved on the sleeve 1221, and the second material picking device 122 completes the material picking work. The rubber ring 103 opened at the opening seat 22 is sent to the top of the fixture of the pipe joint 101 of the pipe joint 101 through the second material picking device 122. The second material picking device 122 descends to make the sleeve 1221 sleeved on the corresponding height position of the pipe end 102. The cylinder 1223 is retracted to make the push plate 1222 push the rubber ring 103 on the sleeve 1221 downward, push the rubber ring 103 downward out of the range of the sleeve 1221 and then sleeve it on the pipe end 102. The pipe end 102 facing the second material picking device 122 is changed by the rotation of the fixture of the pipe joint 101, and then the rubber ring 103 is sleeved on each pipe end 102.

[0027] like Figure 1 As shown, the spacing between the material receiving seat 21 and the opening seat 22 is the same as the spacing between the first material taking device 121 and the second material taking device 122. While the first material taking device 121 sends the rubber ring 103 at the material receiving seat 21 to the opening seat 22, the second material taking device 122 sends the rubber ring 103 at the opening seat 22 to the clamp of the pipe joint 101.
