The tail end of the clamping pins 317 is provided with a tail post 319 that extends into the locking hole 315.

[0053] In the preferred embodiment, the contact surface between the U-shaped groove of the rebar support 311 and the rebar is coated with a wear-resistant and anti-slip coating, and the coating is a silicon carbide wear-resistant material.

[0054] In the preferred embodiment, the layering device 4 includes a material distribution rack 401, a liftable first slide plate 404 is provided on one side of the material distribution rack 401, a third electric cylinder 403 is provided below the first slide plate 404, a first crossbar 406 is provided on one side of the first slide plate 404 perpendicular to the material distribution rack 401, and a plurality of rotatable first rollers 411 are provided on the first crossbar 406.

[0055] On the other side opposite to the first slide plate 404, the material distribution rack 401 is also provided with a liftable second slide plate 408. A fourth electric cylinder 409 is provided below the second slide plate 408. A second crossbar 410 is provided on one side of the second slide plate 408 perpendicular to the material distribution rack 401. Several rotatable second rollers 412 are provided on the second crossbar 410. The first roller 411 and the second roller 412 are both self-powered rollers.

[0056] The top two sides of the material distribution rack 401 are equipped with buffers 413.

[0057] The working principle is as follows: First, the material feeding device 2 is fixedly installed on one side of the material transfer device 3. After the steel bar is welded, lengthened, cut and straightened, it passes through the U-shaped support of the guide seat 222 and enters the V-shaped groove of the driven wheel 202. The steel bar continues to move forward into the driving wheel 203. The driving wheel 203 rotates to make the steel bar move into place faster. When the steel bar moves out of the last driven wheel 202, it will hit the limit plate 206. After the steel bar moves into place, the lifting cylinder 208 pushes upward, so that the lifting plate 209 is lifted upward. The lifting plate 209 has an inclined surface on one side. Lifting upward can make the steel bar roll down onto the slope 221 of the mounting plate 220 and roll into the conveyor line 211.

[0058] The limit plate 206 can be set in the human-machine interface. The signal is sent to the main control module through the human-machine interface to make the second motor 205 rotate, which will lift or lower the limit plate 206. The bottom of the limit plate 206 is equipped with a distance sensor. When the sensor detects that there is a steel bar below, the limit plate 206 will not continue to fall.

[0059] The first motor 204 drives the sprockets in the conveyor line 211 to rotate. The sprockets are coaxially connected by a high-strength steel shaft. The first motor 204 is a high-torque, slow-speed motor. After the steel bar falls to the ramp 221, it rolls down to the conveyor line 211. When the conveyor belt 218 in the conveyor line 211 rotates, it will drive the pusher plate 219 on the conveyor belt 218 to move. The pusher plate 219 slowly delivers the steel bar to the front end of the conveyor line 211. Finally, the steel bar falls between the clamping plate 215 and the guide plate 214 and is caught by the baffle plate 216. When the first sensor 217 senses the steel bar, the first motor 204 stops conveying the steel bar. The first sensor 217 can be a proximity switch or an infrared sensor. The driven wheel 202 and the driving wheel 203 continue to convey the steel bar, but the lifting cylinder 208 does not operate.

[0060] The first electric cylinder 302 in the material transfer device 3 takes the top of the material distribution device 2 as the zero point coordinate, and the steel bar support 311 at the top of the lifting frame 310 takes the top of the material distribution device 2 as the zero point coordinate. After all are zeroed, the steel bar support 311 directly below the guide plate 214 corresponds to the first falling steel bar.

[0061] When the first sensor 217 detects the rebar, the first electric cylinder 302 on the material transfer device 3 has moved the transverse frame 321 to the zero point, and the third electric cylinder 303 raises the lifting frame 310 to the highest point, so that the rebar support 311 is as close as possible to the guide plate 214. When the lifting frame 310 is raised to the highest point and the rebar support 311 is also moved into place, the limit cylinder 212 pulls out the baffle plate 216 at its front end, and the rebar falls into the rebar support 311.

[0062] The second sensor 314 in the rebar support 311 detects the presence of the rebar. Based on the encoder coordinates, the third motor 305, with its lead screw 306 passing through the nut hole 320 on the movable seat 309, rotates to align the locking cylinder 304 on the movable seat 309 with the locking hole 315 on the rebar support 311. Once in position, the locking cylinder 304 inserts its shaft end into the locking hole 315, lifting the tail column 319 in the rebar support 311. This releases the anti-slip pad 318 at the front end of the clamping pin 317, allowing the guide rail to slide freely. After the anti-slip pad 318 is released, the third motor 305 supports the rebar... The frame 311 moves to the top of the other side, the locking cylinder 304 pulls out the shaft end, the clamping pin 317 clamps the slide rail under the action of the spring 316 and the anti-slip pad 318 clamps the slide rail, and the rebar support 311 cannot slide freely. Repeat the above operation to put rebars on all the rebar supports 311. The above structure is symmetrically arranged on both sides of the transfer frame 301. After the rebar support 311 on one side is loaded with rebars, the first electric cylinder 302 moves all the rebar supports 311 to the side close to the layering device 4. A set of devices symmetrically arranged on the other side of the transfer frame 301 repeats the above operation to fill the rebar supports 311 with rebars.

[0063] Before the rebar support 311 moves to the side close to the layering device 4, the third electric cylinder 403 installed on the first support 402 drives the first slide plate 404 to move downward, so that the first roller 411 on the first crossbar 406 is lower than the lowest surface of the rebar on the rebar support 311. The rebar support 311 delivers the rebar above the first roller 411. The third electric cylinder 403 pushes the first slide plate 404 upward to push the rebar to the set height. The rebar support 311 with unloaded rebar is controlled by the first electric cylinder to return to the zero point. Before the rebar support 311 on the symmetrical side of the transfer device 3 delivers the rebar again, the fourth electric cylinder 409 on the second support 407 causes the second slide plate 408 to move downward, so that the second roller 412 on the second crossbar 410 is lower than the lowest surface of the rebar. The rebar support 311 delivers the rebar above the second roller 412. The fourth electric cylinder 409 causes the second slide plate 408 to move upward to unload the rebar. The empty rebar support 311 is sent back to the zero point again.

[0064] The above actions have completed the layering of the reinforcing bars. The first roller 411 and the second roller 412 are to facilitate the axial movement of the reinforcing bars after they are tightened. Their own power can also transport the reinforcing bars to another device.

[0065] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
