[0055] The embodiment of the present invention provides a multifunctional steel bar unloading device, wherein the steel bars herein include straightened steel bars and straight steel bars. Figure 1-Figure 4 As shown, the multifunctional steel bar unloading device includes a frame 1, a material dropping conversion assembly 2 and a material dropping collection assembly 3. The frame 1 is provided with a bottom beam 12 and a top beam 11. The bottom beam 12 and the top beam 11 are both extended along the first direction (X direction), and the top beam 11 is arranged at a high place relative to the bottom beam 12 (there is a height difference along the Z direction); the material dropping conversion assembly 2 is arranged on the top beam 11, and the material dropping conversion assembly 2 is used to selectively drop the sheared steel bars in batches; the material dropping collection assembly 3 includes a hook unloading mechanism 31 and a baffle plate 32. The hook unloading mechanism 31 and the baffle plate 32 are both arranged on the bottom beam 12, and the baffle plate 32 is inclined downward, so that the steel bars can slide downward along the baffle plate 32 to unload; the hook unloading mechanism 31 is located below the baffle plate 32, and the hook unloading mechanism 31 includes a hook 312, and the hook 312 can be rotated to a surface higher than the baffle plate 32 to collect the steel bars.

[0056] like Figure 1-Figure 3 As shown, the sheared steel bars are located on the blanking conversion assembly 2 along the first direction. When the steel bars need to be bent, the steel bar bending machine can be set between the blanking conversion assembly 2 and the unloading collection assembly 3. The blanking conversion assembly 2 can drop the steel bars to the steel bar bending machine for bending operation. When the steel bars do not need to be bent, the blanking conversion assembly 2 can drop the steel bars directly to the hook unloading mechanism 31 of the unloading collection assembly 3. The hook unloading mechanism 31 collects the steel bars. When the hook 312 rotates to be higher than the baffle plate 32, the hook 312 can collect the steel bars for packaging, thereby realizing the selective transportation and loading of the steel bars to the steel bar bending machine, realizing the direct collection of the steel bars sliding downward along the baffle plate 32, and realizing the packaging, collection and unloading of the steel bars on the baffle plate 32, solving the problem of multi-functional unloading of steel bars and improving the production efficiency of steel bars.

[0057] In some embodiments, the material dropping conversion assembly 2 includes a conversion support beam 21, a first unloading door 22, a second unloading door 23 and a third unloading door 24. The top end of the conversion support beam 21 is fixedly connected to the top beam 11, and the bottom end of the conversion support beam 21 is tilted downward; the first unloading door 22 is rotatably disposed on the conversion support beam 21, and the sheared steel bars are located between the first unloading door 22 and the conversion support beam 21; the second unloading door 23 is rotatably disposed on the top beam 11 and is located at the outlet of the first unloading door 22. When the first unloading door 22 is opened, the steel bars can fall between the second unloading door 23 and the conversion support beam 21; the third unloading door 24 is rotatably disposed on the top beam 11 and is located at the outlet of the second unloading door 23. When the second unloading door 23 is opened, the steel bars can fall between the third unloading door 24 and the conversion support beam 21. After the third unloading door 24 is opened, the steel bars drop, and the opening angles of the first unloading door 22, the second unloading door 23 and the third unloading door 24 are preset.

[0058] like Figure 5 and Figure 6As shown, in the blanking conversion assembly 2, the conversion support beam 21 includes an integral structure or a vertical section and an inclined section connected to each other, wherein the top end of the vertical section is connected to the top beam 11, and the bottom end of the vertical section is connected to the inclined section, and the inclined section is inclined from top to bottom to facilitate the steel bars to slide down under their own gravity. In order to facilitate the controlled rotation of the first unloading door 22, a first support 221 is provided on the top beam 11, and the first support 221 is rotatably installed with the first cylinder 223 through the first pin shaft 222. The output end of the first cylinder 223 is connected to the first fisheye joint 224, and the first fisheye joint 224 is rotatably connected to the first unloading door 22 through the second pin shaft 225. In this embodiment, the first unloading door 22 is a movable angle steel, and a fixed angle steel 226 is provided on the conversion support beam 21. The movable angle steel is rotatably installed on the fixed angle steel 226 through the third pin shaft 227. The fixed angle steel 226 is opposite to the opening of the movable angle steel to form a accommodating space for the steel bars. The first cylinder 223 can drive the first unloading door 22 to rotate open and close, so that the steel bars can be dropped one by one or all of them. In order to facilitate the rotation control of the second unloading door 23 and the third unloading door 24, a second support 231 is also provided on the top beam 11, and the second support 231 is rotatably installed on the second cylinder 233 and the third cylinder 234 through a fourth pin shaft 232. The second unloading door 23 and the third unloading door 24 are both made of angle steel or L-shaped components, wherein one end of the second unloading door 23 and the third unloading door 24 are rotatably installed on the top beam 11 through a fifth pin shaft 235 respectively, and the first unloading door 22, the second unloading door 23 and the third unloading door 24 are arranged in sequence at intervals along the inclined section of the conversion support beam 21, and the corners of the second unloading door 23 and the third unloading door 24 are rotatably installed on the second fisheye joint 237 at the output end of the second cylinder 233 and the third cylinder 234 respectively through a sixth pin shaft 236. The second cylinder 233 and the third cylinder 234 can be used to drive the second discharge door 23 and the third discharge door 24 to rotate, open and close, respectively, so that the steel bars that meet the quantity requirements are dropped in batches. The first cylinder 223, the second cylinder 233 and the third cylinder 234 are controlled separately to realize the sequential downward dropping of the steel bars, which is convenient for controlling the number of steel bars dropped, especially when the steel bar bending machine can simultaneously bend more than two steel bars, the drop conversion assembly 2 can realize the simultaneous loading of multiple steel bars, realize accurate loading, and improve the loading efficiency; when the steel bars are not bent but directly discharged and collected, the drop conversion assembly 2 can realize the simultaneous dropping of multiple steel bars to improve the packaging or loading efficiency.

[0059] In some embodiments, the material dropping conversion assembly 2 further includes a fourth unloading door 25, which is rotatably disposed at the bottom end of the conversion support beam 21, and the fourth unloading door 25 can be rotated to change the dropping direction of the steel bars.

[0060] For example Figure 6A fixed block 251 is fixedly installed at the bottom end of the conversion support beam 21, and the fourth unloading door 25 is rotatably installed on the fixed block 251 through the seventh pin shaft 252. A third support 253 is provided on the top bottom surface of the inclined section of the conversion support beam 21, and a fourth cylinder 254 is rotatably installed on the third support 253. A third fisheye joint 255 is provided at the output end of the fourth cylinder 254. The third fisheye joint 255 is rotatably connected to the end of the fourth unloading door 25 away from the conversion support beam 21 through the eighth pin shaft 256. The fourth cylinder 254 can drive the fourth unloading door 25 to rotate around the seventh pin shaft 252. When the steel bars are unloaded, the output end of the fourth cylinder 254 contracts, and the fourth unloading door 25 can be rotated downward to connect the hook unloading mechanism 31 and the baffle plate 32, so as to realize the downward sliding unloading of the steel bars; when bending is required, the output rod of the fourth cylinder 254 extends to keep the fourth unloading door 25 in the extended position with the conversion support beam 21, so that the steel bars can slide along the fourth unloading door 25 to the steel bar bending machine for unloading. It should be noted that in order to facilitate the loading and unloading of steel bars in the steel bar bending machine, the inclination direction of the bottom inclined section of the conversion support beam 21 is opposite to the inclination direction of the baffle plate 32, so that there is enough space between the top beam 11 and the bottom beam 12 to install the steel bar bending machine. The direction of the steel bar falling can be changed by rotating the fourth unloading door 25, thereby realizing the selection control of multifunctional falling and unloading.

[0061] In the above embodiment, the first cylinder 223, the second cylinder 233, the third cylinder 234 and the fourth cylinder 254 are provided in plurality and are arranged at intervals along the first direction to provide a balanced driving force. Of course, the cylinders in this article can also be replaced by oil cylinders or linear motors.

[0062] In some embodiments, the hook unloading mechanism 31 also includes a support seat 311 and a rotating shaft 3112. A plurality of support seats 311 are arranged on the bottom beam 12 at intervals along the first direction, and a material blocking plate 32 is arranged on the top of the support seat 311; the rotating shaft 3112 is rotatably installed between the plurality of support seats 311, the rotating shaft 3112 is extended along the first direction, and the hook 312 is fixed on the rotating shaft 3112. The rotating shaft 3112 can drive the plurality of hooks 312 to rotate upward synchronously to a position higher than the material blocking plate 32 to collect the steel bars.

[0063] like Figure 8 and Fig. 9For example, two rotating shafts 3112 are arranged on multiple supporting seats 311. The two rotating shafts 3112 are parallel to each other and arranged at intervals on the supporting seats 311. Multiple hooks 312 are fixedly connected to each rotating shaft 3112. The rotating shafts 3112 are located below the material blocking plate 32. The hook bodies 3127 of the hooks 312 are bent upward. When the hooks 312 rotate upward, they can be higher than the material blocking plate 32 to block the steel bars from sliding down, so as to collect the steel bars and facilitate packaging. The material blocking plates 32 are arranged at the tops of the multiple supporting seats 311. The material blocking plates 32 are arranged to be inclined from top to bottom so that the steel bars can slide downward under their own gravity. The two rotating shafts 3112 have a height difference in the Z direction and are arranged on the support seat 311 at intervals along the Y direction. The support seat 311 is provided with a diamond seat bearing 3111, and the rotating shaft 3112 is penetrated and installed on the diamond seat bearing 3111. A double-ear base 3121 is provided on the bottom beam 12, and a fourteenth pin 3122 is rotatably installed on the double-ear base 3121. A single-ear base 3124 is provided at the bottom end of the hook cylinder 3123, and the single-ear base 3124 is rotatably installed on the fourteenth pin 31 22, the output end of the hook cylinder 3123 is provided with a sixth fisheye joint 3125, the rotating shaft 3112 is provided with a first clamping block 3113 and a second clamping block 3114 of the rotating shaft 3112, the sixth fisheye joint 3125 is rotatably connected to the first clamping block 3113 or the second clamping block 3114 through the fifteenth pin 3126, and the first clamping block 3113 and the second clamping block 3114 are connected and clamped on the rotating shaft 3112 through bolts. When the output end of the hook cylinder 3123 telescopically moves, the rotating shaft 3112 is driven to rotate through the first clamping block 3113 or the second clamping block 3114, thereby driving the hook 312 on the rotating shaft 3112 to rotate synchronously. The hook 312 includes a hook body 3127 and a stopper 3128. One end of the stopper 3128 and the hook body 3127 are connected by bolts and clamp the rotating shaft 3112 to be fixed on the rotating shaft 3112. The material blocking plate 32 is provided with an avoidance groove 322. When the hook 312 on the rotating shaft 3112 at a high position rotates upward, it can rotate to a surface higher than the material blocking plate 32 through the avoidance groove 322; when the hook 312 on the rotating shaft 3112 at a low position rotates upward, it can rotate to a surface higher than the material blocking plate 32 through the end (bottom end) of the material blocking plate 32. Further, the support seat 311 is also provided with a material blocking hook 313. The material blocking hook 313 is extended along the bottom end of the material blocking plate 32. The hook 312 and the material blocking hook 313 are staggered to avoid interference. When the steel bar slides down to the material blocking hook 313, the material blocking hook 313 can guide the steel bar to a designated position such as a loading position.

[0064] In some embodiments, the unloading collection assembly 3 can collect the bent steel bars after being bent by the steel bar bending machine, and can also collect the steel bars in the blanking conversion assembly 2, which can be switched and controlled as needed. In this embodiment, the unloading collection assembly 3 also includes a guide bar assembly, which is rotatably arranged at the top of the baffle plate 32, and the guide bar assembly can rotatably support the steel bars.

[0065] like Figure 3 and Fig. 9 As shown, the inclination direction of the bottom inclined section of the conversion support beam 21 is opposite to the inclination direction of the baffle plate 32. The length of the steel bar is generally long. In order to achieve accurate unloading of the steel bar, the top of the baffle plate 32 is rotatably provided with a guide bar assembly. When unloading, the guide bar assembly rotates upward to engage with the bottom end of the conversion support beam 21 (or the fourth unloading door 25), so that the steel bar can be dropped to the guide bar assembly and slide along the baffle plate 32 for unloading. When the steel bar needs to be bent, the guide bar assembly rotates downward to below the baffle plate 32, and the steel bar slides along the conversion support beam 21 and the fourth unloading door 25 and drops to the steel bar bending machine, and then the guide bar assembly can be rotated upward to support the steel bar to ensure the bending quality.

[0066] In some embodiments, the guide bar assembly includes a conversion cylinder 33, a guide bar 34 and a supporting cylinder 35. The conversion cylinder 33 is arranged on the material baffle plate 32. The output end of the conversion cylinder 33 is rotatably installed with the first guard plate 331.

The guide bar 34 is hinged on the second guard plate 351. The supporting cylinder 35 can drive the second guard plate 351 to rotate around the guide bar 34 to support the steel bars.

[0067] like Figure 7-Figure 9A foot seat 321 is provided on the inner side wall of the top end of the baffle plate 32 for rotatably installing the conversion cylinder 33. A fourth fisheye joint 332 is provided at the output end of the conversion cylinder 33. The fourth fisheye joint 332 is rotatably connected to the first guard plate 331 through a ninth pin shaft 333. A tenth pin shaft 334 is arranged on the first guard plate 331 to rotatably connect the first guard plate 331 with the baffle plate 32. When the conversion cylinder 33 is extended or retracted, it can drive the first guard plate 331 to rotate relative to the baffle plate 32. The supporting cylinder 35 is rotatably mounted on the first guard plate 331 through the eleventh pin shaft 352, and the fifth fisheye joint 353 is set at the output end of the supporting cylinder 35, and the fifth fisheye joint 353 is rotatably mounted on the second guard plate 351 through the twelfth pin shaft 354, and the guide bar 34 is rotatably mounted on the second guard plate 351 through the thirteenth pin shaft 355, wherein the twelfth pin shaft 354 and the thirteenth pin shaft 355 are arranged at intervals on the second guard plate 351, and the telescopic movement of the output end of the supporting cylinder 35 can drive the second guard plate 351 to rotate relative to the guide bar 34 to support the steel bars, so that the steel bars can slide along the second guard plate 351 and the guide bar 34 to the material baffle plate 32 for unloading, and when the steel bars are bent, deformation of the middle of the steel bars due to sagging due to gravity can be avoided.

[0071] The embodiment of the present invention further provides a multifunctional steel bar unloading method, which uses the multifunctional steel bar unloading device provided in the above embodiment. The multifunctional steel bar unloading method includes the following steps:

[0072] S1, the sheared steel bar is located in the blanking conversion assembly 2;

[0073] Specifically, Figure 6 As shown, the steel bar is located between the first unloading door 22 and the fixed angle steel 226, and both ends of the first unloading door 22 are open, so as to facilitate the alignment operation of the steel bar at both ends.

[0074] S2, the steel bars are dropped from the drop conversion assembly 2 in batches;

[0075] S3, when the hook 312 is lower than the surface of the baffle plate 32, the steel bars slide downward along the baffle plate 32 for unloading; when the hook 312 rotates to be higher than the surface of the baffle plate 32, the hook 312 collects the steel bars for packaging and unloading.

[0076] In the above multifunctional steel bar unloading method, the material-dropping conversion component 2 realizes precise control of the number of steel bars dropped by dropping in batches and in stages to meet different process requirements, such as the number of two steel bars bent at the same time. The unloading collection component 3 realizes multifunctional unloading of steel bars by setting a hook unloading mechanism 31 and a baffle plate 32, such as the steel bars directly slide down the baffle plate 32 to unload, and when the hook 312 rotates to be higher than the baffle plate 32, the steel bars are packed and unloaded in batches, thereby improving the steel bar production efficiency and meeting different unloading requirements.

[0077] Step S2 specifically includes the following steps:

[0078] S21, the first discharge door 22 of the material drop conversion assembly 2 is opened, and a steel bar is controlled to fall into the second discharge door 23 and then closed;

[0079] S22, the second discharge door 23 is opened, a steel bar falls into the third discharge door 24 and then is closed;

[0080] S23, repeating step S21 and step S22 until the number of steel bars at the third unloading door 24 meets the requirement;

[0081] S24, the fourth discharge door 25 of the blanking conversion assembly 2 rotates toward a side away from the third discharge door 24;

[0082] S25, the third unloading door 24 is opened, and the steel bars slide downward along the guide bar assembly and the baffle plate 32 to drop out.

[0083] Generally, a steel bar bending machine can realize the simultaneous bending production of more than two steel bars. Therefore, by setting the second unloading door 23 and the third unloading door 24, when the number of steel bars at the third unloading door 24 meets the bending demand, the third unloading door 24 is controlled to load the steel bar bending machine, and the loading accuracy is easy to control, and the loading is automatic and efficient. When bending is not required, the first unloading door 22, the second unloading door 23 and the third unloading door 24 are rotated and opened in sequence to unload, so that the steel bars fall into the hook unloading mechanism 31 one by one for unloading and collection, and can be directly collected and loaded or packaged in steps to avoid the cross caused by unloading multiple steel bars at the same time, resulting in jamming.

[0084] During the unloading operation, the rotation angle of the fourth unloading door 25 is matched with the position of the steel bar bending machine and the hook unloading mechanism 31. When the output rod of the fourth cylinder 254 is extended, the fourth unloading door 25 guides the steel bar to the steel bar bending machine in the C-beam 13 to achieve bending and loading. During bending, the guide bar assembly rotates to support the middle position of the steel bar. When the output rod of the fourth cylinder 254 is retracted, the fourth unloading door 25 rotates downward, the steel bar bending machine closes the loading port, and the steel bar falls along the fourth unloading door 25 onto the guide bar assembly and the baffle plate 32 to achieve steel bar unloading collection or packaging collection.
