[0030] In a preferred embodiment, a first sensor 217 is disposed in the material guide plate 214 , and the first sensor 217 may be a proximity switch or an infrared switch.

[0031] In the preferred embodiment, the limiting assembly includes a second motor 205 and a limiting plate 206, and the output shaft of the second motor 205 is provided with a gear 207; A rack is provided on one side of the limit plate 206 close to the gear 207, and the rack is meshed with the gear 207. The limit plate 206 passes through the cross guide rod 210 and is inserted between the mounting plates 220. A sliding guide rail is provided between the limit plate 206 and the cross guide rod 210, and the limit plate 206 can slide up and down in the cross guide rod 210.

[0032] In a preferred embodiment, a first motor 204 is provided below the material distribution frame 201 , and the first motor 204 drives the conveyor line 211 via a chain.

[0033] In the preferred embodiment, a material guide seat 222 is further provided at one end of the material distribution rack 201 for feeding steel bars.

[0034] In the preferred embodiment, the material guide seat 222 is a U-shaped support, and the contact surface between the material guide seat 222 and the steel bar is coated with silicon carbide wear-resistant material. The whole working principle is as follows: first, the material distributing device 2 is fixedly installed to one side of the material moving device 3. After being welded, lengthened, cut and straightened, the steel bar passes through the U-shaped support of the material 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 support the limit plate 206. After the steel bar moves into place, the lifting cylinder 208 pushes upward to make the lifting plate 209 lift upward. A slope is provided on one side of the lifting plate 209. The upward lifting can make the steel bar roll down to the slope 221 of the mounting plate 220 and roll into the conveyor line 211. The limit plate 206 can be set in the human-machine interaction interface, and a signal is sent to the main control module through the human-machine interaction interface to rotate the second motor 205, so as to lift or drop the limit plate 206. A distance sensor is provided at the bottom of the limit plate 206. When the limit plate 206 senses that there are steel bars below, it will not continue to fall down. 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 slope 221, it rolls to the conveyor line 211. When the conveyor belt 218 in the conveyor line 211 rotates, it will drive the push plate 219 on the conveyor belt 218 to move. The push plate 219 slowly sends 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. The first electric cylinder 302 in the material moving device 3 takes the topmost point close to the material distributing device 2 as the zero point coordinate, and the steel bar support 311 on the top of the lifting frame 310 takes the topmost point close to the material distributing device 2 as the zero point coordinate. After all are reset to zero, the steel bar support 311 directly below the material guide plate 214 corresponds to the first steel bar that falls; When the first sensor 217 senses the steel bar, the first electric cylinder 302 on the material moving 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 steel bar support 311 is as close to the material guide plate 214 as possible. When the lifting frame 310 is raised to the highest point and the steel bar support 311 is also moved into place, the limit cylinder 212 pulls out the material blocking plate 216 at its front end, and the steel bar falls into the steel bar support 311; The second sensor 314 in the steel bar support 311 senses the presence of the steel bar, and the third motor 305, according to the encoder coordinate position, the screw rod 306 passes through the nut hole 320 on the moving seat 309, and the screw rod 306 rotates to align the locking cylinder 304 on the moving seat 309 with the locking hole 315 on the steel bar support 311. After moving into place, the locking cylinder 304 inserts its shaft end into the locking hole 315, and the shaft end lifts the tail column 319 in the steel bar support 311, and the anti-skid pad 318 at the front end of the clamping pin 317 is released, and the guide rail can slide freely. After the anti-skid pad 318 is released, the third motor 305 moves the steel bar support The rack 311 moves to the top of the other side, the locking cylinder 304 draws out the shaft end, the clamping pin 317 clamps the slide rail under the action of the spring 316, and the anti-skid pad 318 clamps the slide rail, so that the steel bar bracket 311 cannot slide freely. Repeat the above operation to put steel bars on all the steel bar brackets 311. The above structure is symmetrically arranged on both sides of the material moving rack 301. After the steel bar brackets 311 on one side are loaded with steel bars, the first electric cylinder 302 moves all the steel bar brackets 311 to the side close to the stratification device 4, and repeat the above operation on a group of devices symmetrically arranged on the other side of the material moving rack 301 to load the steel bar brackets 311 with steel bars. Before the steel bar support 311 moves to the side close to the stratification 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 cross bar 406 is lower than the lowest surface of the steel bars on the steel bar support 311, and the steel bar support 311 sends the steel bars to the top of the first roller 411, and the third electric cylinder 403 pushes the first slide plate 404 to move upward, and pushes the steel bars to a set height, and the steel bar support 311 from which the steel bars are unloaded is controlled by the first electric cylinder to return to the zero point, and before the steel bar support 311 on the symmetrical side of the material moving device 3 sends the steel bars again, the fourth electric cylinder 409 on the second support 407 moves the second slide plate 408 downward, so that the second roller 412 on the second cross bar 410 is lower than the lowest surface of the steel bars, and the steel bar support 311 transports the steel bars to the top of the second roller 412, and the fourth electric cylinder 409 moves the second slide plate 408 upward to unload the steel bars, and the remaining steel bar support 311 is sent back to the zero point again; The above actions have completed the layering of the steel bars. The first roller 411 and the second roller 412 are for facilitating the axial movement of the subsequent steel bars after tightening.

[0035] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limiting the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims.
