Then, please still refer to Fig. 9, when the positioning plate 242 (252) contacts the pipe fitting T1, the third servo motor 246 and the fifth servo motor 254 synchronously drive the positioning plate 242 (252) on the push-up plate 241 ( 251) upward displacement (see Figure 5 for cooperation), until the pipe fitting T1 is completely placed on the push-up plate 241 (251) (as shown in Figure 11), and then synchronously driven by the second servo motor 243 and the fourth servo motor 253 The push-up plate 241 (251) moves on the fixed seat 211 to push up the first tube T1 to the corresponding measurement position, and at the same time, the push-up plate 241 (251) and the rubber strip 2412 (2511) block the delivery The remaining tubes T1 on the belt 212 continue to advance (as shown in Figure 12). At this time, the pipe fitting measuring device 26 drives the displacement mechanism 262 Displace on the slide rail 263 (as shown in FIG. 13 ) until the movable plate 2621 and the fixed plate 201 are placed on the two ends of the pipe T1, and then the measurement of the length of the pipe T1 is completed.

After reconfirming the length of the pipe fitting T1, the group feeding device 24 and the independent feeding device 25 will work synchronously according to the length of the pipe fitting T1, so that the second servo motor 243 and the fourth servo motor 253 can be calculated according to the pipe diameter of the pipe fitting T1. After the distance to be displaced, synchronously drive the push-up plate 241 (251) to move on the fixed seat 211 until the pipe fitting T1 is finally positioned at the center of the corresponding chuck group 32 (as shown in FIG. 14 ). At this time, the pipe processing mechanism 3 drives the displacement of the chuck group 32 to clamp the pipe T1 (as shown in Figure 15), and can clamp the pipe T1 with multiple sets of chuck groups 32 according to the length of the pipe T1 (as shown in Figure 16 ~17), in addition, since the chuck set 32 has a large-diameter opening for the feeding mechanism 31 to pass through, even if the end of the pipe fitting T1 cannot be supported by the group feeding device 24 or the independent feeding device 25, it is drooping In this state, it can still be smoothly inserted into the chuck group 32 with a large-diameter opening for clamping, so that the feeding mechanism 31 can stably clamp the end of the pipe fitting T1 and perform pipe fitting processing operations.

When the pipe fittings feeder 2 is used to convey the pipe fittings T2 of non-circular pipes, please cooperate with that shown in Figure 18, the lifting plate 22 can extend the range that can accommodate the pipe fittings T2 by rotating the baffle plate 225, and the pipe fittings are fed Even if the machine 2 extends the lifting plate 22 and rises to the maximum height H, its height H is still lower than that of the traditional overhead feeding belt, so it can reduce the interference of the pipe feeding machine 2 on the space and increase the flexibility of the space configuration in the factory.

Therefore, using the pipe fitting feeder of the present invention can obviously achieve the following effects:

1. The present invention uses a lifting plate to replace the traditional feeding belt to transport the pipe fittings in a high-hanging manner, so that the pipe fittings can be stably transported in a neat arrangement, and prevent the pipe fittings from colliding with each other during the lifting process, thereby improving the processing efficiency and yield of the pipe fittings.

2. The present invention uses the lifting plate to replace the traditional feeding belt to transport the pipes in a high-hanging manner, which can reduce the height of the pipe feeder, reduce the interference of the pipe feeder with the space, and increase the flexibility of the space configuration in the factory.

3. When the lifting plate of the present invention is used for non-circular pipes, the baffle plate can be pivoted to extend the range of pipe fittings that can be accommodated. Even if manual piping is required, it can reduce the number of manual discharges and increase the feeding efficiency of pipe fittings.

4. The present invention combines the group feeding device with the independent feeding device, so that the feeding process can be operated synchronously by the group feeding device and the independent feeding device according to the length of the pipe, or only by the group feeding device. To reduce the workload of the pipe feeder.
