[0077] like Figure 2 As shown, in the present invention, the positioning seat 1 includes a seat body, and two hanging buckle slots 11 are opened on the seat body. Long grooves for the hanging buckle 10 to extend into are formed on both sides of the seat body corresponding to the hanging buckle slots 11. When the hanging buckle 10 is located in the hanging buckle slots 11, the flange 40 is located below the hanging buckle 10.

[0078] Specifically, such as Figure 3 and Figure 4As shown, the buckle conveying device 2 of the present invention includes a buckle conveying track 21, a discharge baffle 22 fixed at the outlet of the buckle conveying track 21, and a buckle ejecting mechanism 23 fixed below the buckle conveying track 21. The discharge baffle 22 is provided with two discharge ports 221. The shape of the discharge port 221 corresponds to the shape of the buckle 10. When the disc 200 rotates the positioning seat 1 to the buckle conveying device 2, the two discharge ports 221 respectively correspond to the positions of the two buckle slots 11. A buckle conveying channel is provided in the buckle conveying track 21 corresponding to the discharge port 221, and a discharge seat is provided at the bottom of the buckle conveying track 21. 24. A discharging block 25 is provided on the upper part of the discharging seat 24, which is close to one side of the discharging baffle 22 and can slide up and down. Two hanging buckle troughs 251 for accommodating the hanging buckle 10 are correspondingly provided at the lower parts of both sides of the discharging block 25. The hanging buckle troughs 251 correspond to the shape of the hanging buckle 10, and the hanging buckle troughs 251 correspond to the outlet of the hanging buckle conveying channel. The horizontal positions of the hanging buckle troughs 251 are higher than the horizontal position of the discharging port 221. A return spring 26 is provided between the bottom of the discharging block 25 and the discharging seat 24. The top of the return spring 26 abuts against the bottom of the discharging block 25, and the bottom of the return spring 26 abuts against the top of the discharging seat 24.

[0079] The hanging buckle ejection mechanism 23 includes an ejection cylinder 231 and a push rod 232 arranged at the output end of the ejection cylinder 231, and the push rod 232 corresponds to the position of the discharge port 221; accordingly, the hanging buckle ejection mechanism 23 is correspondingly provided with two push rods 232; the hanging buckle ejection mechanism 23 also includes a push rod 233 horizontally arranged at the output end of the ejection cylinder 231, the push rod 233 and the two push rods 232 are all inserted into the discharge seat 24 and are arranged in the direction of the discharge baffle 22, and accordingly, a through long groove is provided in the discharge seat 24 for the push rod 233 and the push rod 232 to extend into, and the length of the push rod 233 is greater than that of the two push rods 232 The push rod 233 is located below the two push rods 232, and a top column 252 is provided at the bottom of the middle of the discharge block 25 corresponding to the position of the push rod 233. The middle part of the top column 252 is provided with an opening 253 for the push rod 233 to just pass through. The push rod 233 has a first inclined surface 234 at the end close to the discharge baffle 22, and a second inclined surface 254 is provided on the side of the opening 253 corresponding to the push rod 233 that cooperates with the first inclined surface 234. When the first inclined surface 234 hits the second inclined surface 254, it drives the top column 252 to move downward. When the push rod 233 is located at the opening 253, the hanging trough 251 and the discharge port 221 are at the same horizontal position.

[0080] The operating principle of the hook conveying device 2 of the present invention is as follows:

[0081] When the buckle 10 is unloaded, it is transported to the buckle conveying track 21 through a conventional vibrating plate (not shown in the figure) or a vibrating seat (not shown in the figure), and the buckle 10 falls into the buckle material trough 251 at the bottom of the discharge block 25 through the buckle conveying channel. At this time, since the buckle material trough 251 is misaligned with the discharge port 221, the buckle 10 in the buckle material trough 251 is blocked by the discharge baffle 22; when the ejection cylinder 231 moves toward the position of the discharge baffle 22, it drives the push rod 233 to move toward the ejector column 252, so that the first inclined surface 234 touches the second inclined surface 254 and drives the ejector column 252 and the discharge block 25 The compressed return spring 26 moves downward, causing the buckle trough 251 to move downward to the same horizontal position as the discharge port 221, and then the ejection cylinder 231 continues to move toward the position of the discharge baffle 22, causing the push rod 233 to pass through the opening 253, and the two ejector rods 232 immediately eject the buckle 10 in the buckle trough 251 from the discharge port 221 to the buckle slot 11 to complete the discharge. After the discharge is completed, the ejection cylinder 231 retracts, and the discharge block 25 moves upward and returns to its original position under the rebound action of the return spring 26, so that the buckle trough 251 is staggered with the discharge port 221. At this time, the unloading operation of the buckle 10 can be carried out again.

[0082] like Figure 5 and Figure 6 As shown, the hook conveying device 3 of the present invention includes a hook conveying track 31 and a hook ejecting mechanism provided at the outlet of the hook conveying track 31. The hook ejecting mechanism includes a base 32, a vertical plate 33 fixed to one side of the base 32, a top stopper 34 fixed to the other side of the base 32, an ejecting portion 35 slidably passed through the middle of the base 32, and a top driving mechanism (not shown in the figure) provided below the ejecting portion 35 for pushing the ejecting portion 35 upward. Accordingly, the hook conveying track 31 is provided with two sets of conveying channels for conveying the hooks 20 corresponding to the two hook slots 11.

[0083] The ejection portion 35 includes a first seat body 351 and a second seat body 352 located above the first seat body 351, and a connecting block 353 for connecting the first seat body 351 and the second seat body 352. The connecting blocks 353 are respectively located on both sides of the first seat body 351 and the second seat body 352. The first seat body 351 and the second seat body 352 are both fixed between the two connecting blocks 353. A compression spring 354 is provided between the first seat body 351 and the second seat body 352. Accordingly, a buffer space is provided between the first seat body 351 and the second seat body 352. The compression spring 354 is located in the buffer space, and the upper and lower ends of the compression spring 354 are respectively connected to the top of the first seat body 351 and the bottom of the second seat body 352 The bottom of the first seat body 351 has a lifting block 355, which extends downward through the base 32 and extends below the base 32 for the push-up driving mechanism to push against. The top of the ejection portion 35 is provided with an ejection seat 36. Accordingly, there are two ejection seats 36, and the two ejection seats 36 correspond to two groups of outlets of the conveying channel for conveying the hook 20. A lifting rod 356 is provided at the top of the first seat body 351 corresponding to the position of the ejection seat 36. The lifting rod 356 passes through the second seat body 352 and is located at the bottom of the ejection seat 36. Accordingly, a through space for the lifting rod 356 to extend into is opened on the second seat body 352, and a protrusion 357 that can resist the push-up block 34 is provided on the second seat body 352.

[0084] The top of the ejector seat 36 is provided with a bearing portion 361 for bearing the hook 20 and a limiting portion 37 for fixing the hook 20 on the bearing portion 361. The middle portion of the limiting portion 37 is rotatably mounted on the ejector seat 36 via a rotating shaft. One end of the limiting portion 37 is a limiting ridge 371 located above the bearing portion 361, and the other end is a first clamping block 372 protruding toward the vertical plate 33. There is a space between the limiting ridge 371 and the bearing portion 361 for placing the hook 20 (the hook 20 is located between the limiting ridge 371 and the bearing portion 361 after exiting the exit of the hook conveying track 31). There is a movable space between the first clamping block 372 and the ejection seat 36, and the movable space is for the limiting portion 37 to rotate toward the ejection seat 36. A second clamping block 331 is protruded on the upper side of the vertical plate 33 toward the ejection portion 35, and is abutted against the first clamping block 372. The first clamping block 372 is located below the second clamping block 331, and the second clamping block 331 is located on the upward movement path of the first clamping block 372. The weight of the first clamping block 372 is greater than the weight of the limiting protrusion 371 (to facilitate the limiting portion 37 to rotate when the first clamping block 372 moves upward and touches the second clamping block 331).

[0085] The operating principle of the hook conveying device 3 of the present invention is as follows:

[0086] After the positioning seat 1 equipped with the hook 10 rotates to the hook conveying device 3, the bearing portion 361 is located just below the hook 10, and the hook conveying track 31 conveys the hook 20 to the bearing portion 361, so that the hook 20 is located between the bearing portion 361 and the limiting ridge 371 and is limited by the limiting ridge 371 to prevent the hook 20 from shaking or sliding. At this time, the top driving mechanism moves upward to drive the lifting block 355 to move upward, and the lifting block 355 drives the first seat body 351 to move upward. Since the first seat body 351 and the second seat body 352 are moved by The connecting block 353 is fixed so that the lifting block 355 can drive the entire ejection part 35 and the ejection seat 36 to move upward. When the second seat body 352 moves upward, the protrusion 357 abuts against the bottom of the lifting block 34 and cannot move further upward (the function of the lifting block 34 is to limit the travel of the second seat body 352 when the ejection part 35 is ejected upward). At this time, the lifting drive mechanism continues to move upward, which will drive the first seat body 351 to compress the compression spring 354, and drive the first seat body 351 and the lifting rod 356 located at the top of the first seat body 351 to continue to move upward. Continuing to move upward, the ejection seat 36 is pushed upward for a short distance (i.e., the compression stroke of the compression spring 354), and the limiting portion 37 on the ejection seat 36 moves upward so that the first clamping block 372 touches the second clamping block 331 on the vertical plate. The first clamping block 372 is blocked by the second clamping block 331 and causes the limiting portion 37 to rotate, that is, the first clamping block 372 rotates toward the ejection seat 36 and drives the limiting protrusion 371 to rotate away from the supporting portion 361, so that the supporting portion 361 pushes the hook 20 out and opens the hole 5 on the hook 20. 0 is fixed on the flange 40 at the bottom of the buckle 10; preferably, the top surface of the bearing portion 361 is set to correspond to the shape of the hook 20, and the top surface of the bearing portion 361 is provided with a recess for the flange 40 at the bottom of the buckle 10 to be inserted, so that the flange 40 at the bottom of the buckle 10 can pass through the hole 50 in the middle of the hook 20 when ejected; it should be noted that, in this embodiment, the push-up drive mechanism preferably adopts a conventional telescopic cylinder in the field or other conventional drive mechanism that can achieve up and down movement, and the specific structure of this embodiment will not be described in detail here.

[0087] Preferably, the frame 100 is also provided with a hook detection mechanism 6 for detecting whether the hook 20 is installed on the hook 10. The hook detection mechanism 6 includes a first mounting plate 61 and a first sensing mechanism 62 fixed on the first mounting plate 61. When the positioning seat 1 with the hook 10 and the hook 20 is rotated to the hook detection mechanism 6, the first sensing mechanism 62 is aligned with the position of the hook 20. It should be noted that the first sensing mechanism 62 is preferably a conventional distance sensor in this field.

[0088] like Figure 7 and Figure 8As shown, the straight-tube conveying device 4 of the present invention includes two vertically arranged straight-tube feeding chutes 41, a hook clamping mechanism 42 for clamping the hook 20 in the hook slot 11, a chute abutting top 43 for ejecting the straight tube 30 to the bottom of the hook 20, and a straight-tube ejecting mechanism 44 for ejecting the straight tube 30 to the hook 20. The chute abutting top 43 is arranged below the straight-tube feeding chutes 41. Accordingly, the two straight-tube feeding chutes 41 correspond to the positions of the two hook slots 11.
