[0064] Embodiment 1

[0065] like Figure 1-Figure 11 As shown, the present invention provides a bidirectional alignment and positioning device, comprising a support mechanism 11, two alignment mechanisms 12 and two alignment drive mechanisms 13. The support mechanism 11 is provided with an alignment channel 111, the two alignment mechanisms 12 are respectively slidably arranged on the support mechanism 11, the two alignment drive mechanisms 13 are respectively installed on the support mechanism 11, the output end of each alignment drive mechanism 13 is connected to an alignment mechanism 12, and the two alignment drive mechanisms 13 can drive the two alignment mechanisms 12 to move toward each other, abut against and align the two ends of the steel bar 100 in the alignment channel 111.

[0066] In the present invention, the sheared steel bars 100 are fed into the bidirectional alignment channel 111, and then the alignment mechanisms 12 at both ends of the length direction of the alignment channel 111 are driven by the alignment drive mechanism 13 to perform bidirectional alignment and positioning on the steel bars 100. The positioning is accurate, no manual operation is required, the labor intensity is reduced, the production efficiency is improved, it is safe and reliable, the degree of automation is high, and the operation is stable.

[0067] Alternatively, if Figure 2 As shown, the bidirectional alignment and positioning device further includes a blanking drive mechanism 14 and a blanking bracket 15. The blanking bracket 15 is rotatably connected to the support mechanism 11 and can block a side port of the alignment channel 111. The blanking drive mechanism 14 is arranged on the support mechanism 11 and can drive the blanking bracket 15 to rotate. The arrangement of the blanking drive mechanism 14 can control the blanking bracket 15 to open in time and accurately to output the aligned steel bars 100.

[0068] In this embodiment, the blanking drive mechanism 14 is a cylinder, whose cylinder body is rotatably connected to the support mechanism 11, and the piston rod is rotatably connected to the blanking bracket 15. The alignment channel 111 is vertically connected. In the initial state, the blanking drive mechanism 14 drives the blanking bracket 15 to close the bottom opening of the alignment channel 111, and the steel bar 100 entering the alignment channel 111 falls on the blanking bracket 15. After the alignment of the alignment mechanism 12 is completed, the blanking drive mechanism 14 drives the blanking bracket 15 to rotate and open the set angle, and the steel bar 100 is output along the blanking bracket 15 under the action of its own gravity.

[0069] Alternatively, if Figure 5 and Figure 6As shown, the alignment mechanism 12 includes a sliding frame 121, an alignment frame 122 and an elastic component 123. The sliding frame 121 is slidably arranged on the support mechanism 11 along a first direction and is connected to the output end of the alignment driving mechanism 13. The first direction is parallel to the length direction of the alignment channel 111. The alignment frame 122 is slidably connected to the sliding frame 121 along the first direction and can abut against the steel bar 100. The elastic component 123 is sandwiched between the sliding frame 121 and the alignment frame 122. The elastic component 123 sandwiched between the sliding frame 121 and the alignment frame 122 can play a buffering role when the alignment frame 122 abuts against the end of the steel bar 100, effectively avoiding the occurrence of the situation where the steel bar 100 is hit by the alignment frame 122 and the end is bent and deformed, thereby ensuring the quality and reliability of the alignment operation.

[0070] Specifically, Figure 6 As shown, the sliding frame 121 includes a fixed seat 1211, a support shaft 1212 fixedly connected to the fixed seat 1211, a running wheel 1213 rotatably arranged on the support shaft 1212, and a fixing plate 1214 fixedly connected to the fixed seat 1211. The running wheel 1213 can run on a running track on one side of the alignment channel 111 on the support mechanism 11, and the fixing plate 1214 is connected to the output end of the alignment driving mechanism 13.

[0071] More specifically, Figure 6 As shown, the alignment frame 122 includes an alignment plate 1221 for abutting against the steel bar 100, a support rod 1222 with one end connected to the alignment plate 1221 and the other end inserted into a guide sleeve of the fixing seat 1211, and a pin 1223 for locking and connecting the support rod 1222 and the guide sleeve.

[0072] In this embodiment, the elastic component 123 is a spring, one end of which abuts against the alignment plate 1221 , and the other end of which abuts against the fixing seat 1211 .

[0073] Alternatively, if Figure 3 , Figure 4 and Figure 6 As shown, the alignment drive mechanism 13 includes a travel motor 131, a driving sprocket 132, a driven sprocket 133 and a transmission chain 134. The travel motor 131 is mounted on the support mechanism 11, the driving sprocket 132 is mounted on the output end of the travel motor 131, the driven sprocket 133 is rotatably mounted on the support mechanism 11, and the transmission chain 134 is wound around the driving sprocket 132 and the driven sprocket 133, and is partially connected to the alignment mechanism 12. The above arrangement has a simple structure and reliable transmission, and can accurately drive the alignment mechanism 12 to abut against the steel bars 100 in the alignment channel 111.

[0074] Specifically, Figure 3As shown, a driving shaft is rotatably arranged on the support mechanism 11, and the motor shaft of the walking motor 131 drives the driving shaft to rotate through a sprocket chain mechanism. Two driving sprockets 132 are fixed on the driving shaft at intervals, and the two driving sprockets 132 are connected to two driven sprockets 133 through two transmission chains 134. The two transmission chains 134 are respectively located on both sides of the alignment channel 111 and are respectively connected to the fixed plate 1214.

[0075] More specifically, two support shafts 1212 are arranged on the fixed seat 1211 at intervals and in parallel, and a walking wheel 1213 is arranged at both ends of each support shaft 1212. The fixed seat 1211 moves on the support mechanism 11 through the four walking wheels 1213. The width of the fixed plate 1214 is larger than that of the fixed seat 1211. It extends from both sides of the fixed seat 1211 and is respectively connected to a transmission chain 134. When the walking motor 131 is in operation, the two walking motors 131 can more smoothly drive the sliding frame 121 to move.

[0076] Alternatively, if Figure 2 As shown, the bidirectional alignment and positioning device further includes a feed rack 16, and a material guide surface is provided on the feed rack 16, and the material guide surface can guide the steel bars 100 thereon into the alignment channel 111. The above arrangement can guide the steel bars 100 into the alignment channel 111 more efficiently.

[0077] Specifically, the material guiding surface is inclined, with one end outside the alignment channel 111 and the other end connected to the alignment channel 111. The end outside the alignment channel 111 is higher than the other end, and the steel bars 100 placed thereon can fall into the alignment channel 111 along the material guiding surface under the action of their own gravity.

[0078] The bidirectional alignment and positioning device in this embodiment is also equipped with a feeding device 30, which is arranged on one side of the bidirectional alignment and positioning device, and can receive the steel bars 100 output by the bidirectional alignment and positioning device and move the steel bars 100 to a set position.

[0079] Specifically, Figure 7 As shown, the feeding device 30 includes a transfer mechanism 31 and a pick-and-place mechanism 32. The transfer mechanism 31 is arranged on one side of the bidirectional alignment and positioning device, and a receiving seat 311 is arranged on the transfer mechanism 31. The blanking drive mechanism 14 drives the blanking bracket 15 to rotate and open the set angle, and the blanking bracket 15 is aligned with the receiving seat 311. The steel bar 100 can fall into the receiving seat 311 along the blanking bracket 15 under the action of its own gravity. The pick-and-place mechanism 32 is arranged at the output end of the transfer mechanism 31, and the transfer mechanism 31 can drive the pick-and-place mechanism 32 to move between the first position and the second position to transfer the steel bar 100 in the receiving seat 311.

[0080] More specifically, the pick-and-place mechanism 32 is provided with a first pick-and-place seat 321 and a second pick-and-place seat 322. When the pick-and-place mechanism 32 is operated at the first position, the first pick-and-place seat 321 can take out the steel bar 100 in the receiving seat 311, and the second pick-and-place seat 322 can take out the steel bar 100 at the target position. When the pick-and-place mechanism 32 is operated at the second position, the first pick-and-place seat 321 can place the steel bar 100 thereon at the target position. The above arrangement improves the efficiency of the feeding device 30 in moving and placing the steel bar 100.

[0081] In this embodiment, the receiving seat 311, the first pick-and-place seat 321 and the second pick-and-place seat 322 are all provided with receiving grooves for receiving the steel bars 100, and the groove openings are all facing upward. In addition, the width of the receiving groove can only accommodate one steel bar 100, so that when receiving the steel bars 100, multiple steel bars 100 can only be arranged vertically.

[0082] Specifically, Figure 8 As shown, the transfer mechanism 31 includes a transfer frame 312, two transfer sprockets 313, a transfer chain 314 and a transfer driving component. Among them, the receiving seat 311 is arranged on the transfer frame 312, the two transfer sprockets 313 are respectively rotatably arranged on the transfer frame 312, the transfer chain 314 is wound around the two transfer sprockets 313, and is partially connected to the pick-and-place mechanism 32, and the transfer driving component is arranged on the transfer frame 312, and can drive one transfer sprocket 313 to rotate. The above arrangement has a simple structure and reliable operation.

[0083] In this embodiment, a horizontally extending slide bar is provided on the transfer frame 312, and the pick-and-place mechanism 32 is slidably connected to the slide bar. The transfer driving component is a motor, which drives the pick-and-place mechanism 32 to translate through the transfer sprocket 313 and the transfer chain 314.

[0084] Specifically, the pick-and-place mechanism 32 includes a pick-and-place bracket 323, a pick-and-place movable frame 324, and a pick-and-place driving component 325. The pick-and-place bracket 323 is connected to the output end of the conveying mechanism 31, the pick-and-place movable frame 324 is slidably connected to the pick-and-place bracket 323, the first pick-and-place seat 321 and the second pick-and-place seat 322 are arranged on the pick-and-place movable frame 324 at intervals, and the pick-and-place driving component 325 is arranged on the pick-and-place bracket 323, and can drive the pick-and-place movable frame 324 to move relative to the pick-and-place bracket 323. The above arrangement makes the pick-and-place mechanism 32 more stable in its pick-and-place action on the steel bar 100.

[0085] In this embodiment, the pick-up and placement bracket 323 is slidably connected to the sliding rod on the transfer frame 312, and is connected to the transfer chain 314. The pick-up and placement bracket 323 is provided with a vertically through guide hole, and the pick-up and placement movable frame 324 is provided with a vertically extending guide shaft, which is passed through the guide hole. The pick-up and placement driving component 325 is a lifting cylinder, the cylinder body is connected to the pick-up and placement bracket 323, and the piston rod is connected to the pick-up and placement movable frame 324.

[0086] The specific working process of the bidirectional alignment and positioning device in this embodiment is as follows:

[0087] Step 1: The blanking bracket 15 is in the initial position, blocking the bottom port of the alignment channel 111, and the sheared steel bars 100 enter the alignment channel 111 through the feeding bracket 16.

[0088] Step 2: The two alignment drive mechanisms 13 drive the two alignment mechanisms 12 to move toward each other, and the alignment plates 1221 abut against and align the two ends of the steel bars 100 in the alignment channel 111 .

[0089] Step 3: The blanking driving mechanism 14 drives the blanking bracket 15 to rotate and open to a set angle, and the steel bar 100 moves along the blanking bracket 15 to the receiving groove of the receiving seat 311 under the action of its own gravity.

[0090] Step 4: Figure 8 As shown, the transfer mechanism 31 drives the pick-and-place mechanism 32 to move to the first position, the first pick-and-place seat 321 moves to below the receiving seat 311, and the second pick-and-place seat 322 moves to below the target position.

[0091] Step 5: Fig. 9 As shown, the pick-and-place driving component 325 drives the pick-and-place movable frame 324 to rise relative to the pick-and-place bracket 323 , and the steel bar 100 is transferred from the receiving groove of the receiving seat 311 to the receiving groove of the first pick-and-place seat 321 .

[0092] Step 6: Fig.10 As shown, the transfer mechanism 31 drives the pick-and-place mechanism 32 to move to the second position, and the first pick-and-place seat 321 moves to above the target position.

[0093] Step 7: Fig.11 As shown, the pick-and-place driving component 325 drives the pick-and-place movable frame 324 to fall relative to the pick-and-place bracket 323, and the steel bar 100 rotates from the receiving groove of the first pick-and-place seat 321 to the target position.

[0095] This embodiment provides a bidirectional bending device, including two bending main machines 20 and the bidirectional alignment and positioning device in the first embodiment. The two bending main machines 20 can bend the steel bars 100 output by the bidirectional alignment and positioning device.

[0096] Specifically, the bidirectional bending device further includes a feeding device 30, which is arranged on one side of the bidirectional alignment and positioning device, and can receive the steel bars 100 output by the bidirectional alignment and positioning device, and transfer the steel bars 100 to the U-shaped grooves 21 of the central axes of the two bending main machines 20.

When the pick-and-place mechanism 32 is operated at the first position, the first pick-and-place seat 321 can take out the steel bars 100 in the receiving seat 311, and the second pick-and-place seat 322 can take out the steel bars 100 in the U-shaped groove 21. When the pick-and-place mechanism 32 is operated at the second position, the first pick-and-place seat 321 can place the steel bars 100 thereon into the U-shaped groove 21. The above arrangement improves the efficiency of the feeding device 30 in moving and placing the steel bars 100.

[0098] In this embodiment, the receiving seat 311, the first pick-and-place seat 321 and the second pick-and-place seat 322 are all provided with receiving grooves for receiving the steel bars 100, and the groove openings are all facing upward. In addition, the width of the receiving groove can only accommodate one steel bar 100, so that when receiving the steel bars 100, multiple steel bars 100 can only be arranged vertically, so that when they are finally transferred to the U-shaped groove 21, they can be neatly arranged vertically, thereby ensuring the quality of the final bidirectional bending.

[0099] Specifically, the transfer mechanism 31 includes a transfer frame 312, two transfer sprockets 313, a transfer chain 314 and a transfer driving component. Among them, the receiving seat 311 is arranged on the transfer frame 312, the two transfer sprockets 313 are respectively rotatably arranged on the transfer frame 312, the transfer chain 314 is wound around the two transfer sprockets 313, and is partially connected to the pick-and-place mechanism 32, and the transfer driving component is arranged on the transfer frame 312, and can drive one transfer sprocket 313 to rotate.

[0112] Step 7: Fig.11 As shown, the pick-and-place driving component 325 drives the pick-and-place movable frame 324 to fall relative to the pick-and-place bracket 323 , and the steel bar 100 rotates from the receiving groove of the first pick-and-place seat 321 to the U-shaped groove 21 .

[0113] Step 8: The two bending machines 20 operate to bend the steel bars 100 in both directions.

[0114] Step nine, when the receiving groove of the receiving seat 311 is filled with steel bars 100 again, the transfer mechanism 31 drives the pick-and-place mechanism 32 to move to the first position, the first pick-and-place seat 321 moves to the bottom of the receiving seat 311, and the second pick-and-place seat 322 moves to the bottom of the U-shaped groove 21 of the central axis of the two bending main machines 20.

[0115] Step 10, the pick-and-place driving component 325 drives the pick-and-place movable frame 324 to rise relative to the pick-and-place bracket 323, and the steel bar 100 is transferred from the receiving groove of the receiving seat 311 to the receiving groove of the first pick-and-place seat 321, and the bent steel bar 100 on the U-shaped groove 21 of the central axis of the two bending main machines 20 is transferred to the receiving groove of the second pick-and-place seat 322.
