Compared with the prior art, in the present invention, since the size of the clamping space inside the hanger 2 is adjustable, it can be compatible with loading thin and hard boards, effectively improving the utilization rate of the hanger.

[0020] In this embodiment, a waiting station is arranged at a position adjacent to the hanger opening station 12. Specifically, as shown in Figures 1 to 3 a temporary storage station 13 is provided on the front side of the frame body 1. The front conveying rail 10 passes through the hanger opening station 12 and the temporary storage station 13 in sequence, and the temporary storage station 13 is used for temporarily storing the hanger 2.

[0023] Regarding the specific structure of the upper elastic locking mechanism 23, in this embodiment, please refer to Figure 9The upper ends of the upper cross beam 20 are respectively provided with upper sliders 201, the upper ends of the vertical rods 22 are connected to the upper sliders 201, the upper sliders 201 are provided with two upper slide grooves 202, the upper elastic locking mechanism 23 includes an upper locking piece 230, an upper pressing piece 231 and two springs 232, the upper locking piece 230 includes upper and lower limiting posts 233, the two limiting posts 233 are respectively located in the two upper slide grooves 202 and the two are slidably matched, the limiting posts 233 pass through the upper cross beam 20, and the ends of the two limiting posts 233 are respectively fixedly connected to the upper pressing piece 231, two springs 232 are respectively sleeved on two limit columns 233, and the springs 232 elastically abut between the upper pressing plate 231 and the upper crossbeam 20, the upper slider 201 is provided with upper positioning holes 203 uniformly distributed in sequence along the transverse direction, and the upper locking plate 230 is provided with a locking column 234 on the side facing the upper slider 201, and the locking column 234 is driven to be inserted into the upper positioning hole 203 by the elastic force applied by the springs 232, and the upper opening and closing mechanism 16 drives the upper elastic locking mechanism 23 to open by applying pressure to the upper pressing plate 231.

[0024] In the above structure, when the upper opening and closing mechanism 16 applies pressure to the upper pressing plate 231, the upper pressing plate 231 pushes the upper locking plate 230 backwards through the two limit columns 233 to separate the locking column 234 from the upper positioning hole 203. At this time, the upper slider 201 can slide laterally, and the upper elastic locking mechanism 23 is in an open state. When the upper opening and closing mechanism 16 removes the pressure applied to the upper pressing plate 231, the upper pressing plate 231 is pushed forward under the action of two springs 232, and the upper locking plate 230 drives the locking column 234 to be stuck in the upper positioning hole 203, thereby realizing re-locking after lateral adjustment. The above structure realizes the elastic locking and unlocking functions, which is convenient for the lateral adjustment mechanism 18 to implement the lateral adjustment toggle action.

[0025] For the preferred structure of the lower elastic locking mechanism 24, see Figure 8The two ends of the lower cross beam 21 are respectively provided with lower sliders 211, the lower ends of the vertical rods 22 are connected to the lower sliders 211, the lower sliders 211 are inserted into the horizontal slide grooves 212 on the side of the lower cross beam 21, and the lower sliders 211 are slidably matched with the horizontal slide grooves 212, the lower elastic locking mechanism 24 includes a cover plate 240, a pressure rod support 241 and an L-shaped pressure rod 242, the cover plate 240 is fixed to the side of the lower cross beam 21, and the cover plate 240 covers the horizontal slide grooves 212, the pressure rod support 241 is fixed to the outer side of the cover plate 240, and the surface of the lower slider 211 is uniformly distributed with sliding The cover plate 240 has a block tooth 213, and a clearance opening 243 is provided on the cover plate 240 corresponding to the slider tooth 213. The L-shaped pressure rod 242 is hingedly matched with the pressure rod support 241. The first end of the L-shaped pressure rod 242 passes through the clearance opening 243 and is engaged with the slider tooth 213. A pressure rod spring is clamped between the second end of the L-shaped pressure rod 242 and the cover plate 240. The elastic force applied by the pressure rod spring drives the first end of the L-shaped pressure rod 242 to press against the slider tooth 213. The lower opening and closing mechanism 17 drives the lower elastic locking mechanism 24 to open by applying pressure to the second end of the L-shaped pressure rod 242.

[0026] In the above structure, the pressure rod spring (not marked) is clamped between the second end of the L-shaped pressure rod 242 and the cover plate 240, and is used to apply elastic force to the second end of the L-shaped pressure rod 242, so that its first end is pressed against the slider teeth 213, thereby achieving a locking function. When the hanger 2 runs to the hanger opening station 12, the lower opening and closing mechanism 17 is used to apply pressure to the second end of the L-shaped pressure rod 242, and based on the lever principle, the elastic force of the pressure rod spring (not marked) is overcome to drive the first end of the L-shaped pressure rod 242 to separate from the slider teeth 213, thereby opening the lower elastic locking mechanism 24.

The driving shaft of the lateral adjustment motor 180 is coaxially connected to the middle input shaft of the T-shaped transmission mechanism 181. The two lateral screw rods 182 are coaxially connected to the output shafts on both sides of the T-shaped transmission mechanism 181 respectively. The lateral screw rod 182 is used to drive the screw rod pair 183 to move laterally. A lateral adjustment cylinder 184 is fixed to the outer side of the screw rod pair 183. The moving end of the lateral adjustment cylinder 184 is provided with a vertical rod paddle 185.

The lateral adjustment cylinder 184 drives the vertical rod paddle 185 to move forward and backward, so that the vertical rod paddle 185 is close to or away from the left or right side of the vertical rod 22.

[0030] In the above structure, the T-shaped transmission mechanism 181 is also called a T-shaped commutator, and the lateral adjustment motor 180 drives the intermediate shaft of the T-shaped transmission mechanism 181 to rotate, and drives the two lateral screw rods 182 to operate through the output shafts extending on both sides of the T-shaped transmission mechanism 181. Through a reasonable setting of the thread direction, the screw rod pairs 183 on both sides are driven to approach synchronously or synchronously. When the lateral adjustment cylinder 184 moves horizontally to an appropriate position, the lateral adjustment cylinder 184 drives the vertical rod paddle 185 to move forward, so that the vertical rod paddle 185 is close to the left or right side of the vertical rod 22. Under the continuous driving action of the lateral adjustment motor 180, the vertical rod paddle 185 paddles the vertical rod 22 to the left or right, thereby realizing the width adjustment function between the two vertical rods 22.

[0031] To adapt to workpieces of different heights, in the present embodiment, a vertical rod adjustment support 205 is fixed to the end of the upper sliding block 201, and the vertical rod 22 passes through the vertical rod adjustment support 205 and the two slide up and down in cooperation, and a vertical limiting mechanism for locking the vertical rod 22 is provided on the vertical rod adjustment support 205, and a vertical opening and closing cylinder 207 is provided at the upper end of the opening and hanging frame station 12, and a vertical opening and closing push block 208 is provided at the driving end of the vertical opening and closing cylinder 207, and the vertical opening and closing push block 208 is aligned with the vertical limiting mechanism, and the vertical opening and closing push block 208 is used to apply a thrust to the vertical limiting mechanism so that the vertical limiting mechanism releases the lock on the vertical rod 22, and a lifting drive mechanism 19 is provided at the lower end of the opening and hanging frame station 12 for driving the lower cross beam 21 to move up and down.

Figure 12, a vertical limiting mechanism is hinged with an L-shaped lever 206 on the outside of the vertical rod adjusting support 205. The locking end of the L-shaped lever 206 passes through the locking hole on the vertical rod adjusting support 205. When a limiting spring (not marked) at the free end of the L-shaped lever 206 exerts an elastic force, the locking end of the L-shaped lever 206 abuts and engages with the vertical rod teeth 229 on the side of the vertical rod 22. When the vertical opening and closing push block 208 exerts a thrust on the free end of the L-shaped lever 206, the locking end of the L-shaped lever 206 is separated from the vertical rod teeth 229 on the side of the vertical rod 22, thereby realizing the functions of vertical limiting and unlocking.
