In the initial state, the inner rotation rod 210 is at the right end of the arc chute 221, and the inner rotation rod 210 is in the vertical state. When the steel bar 900 falls into the detection position of the detection clamping assembly 200, the steel bar 900 is divided into a small-angle steel bar 900 with an included angle smaller than 90 degrees and a large-angle steel bar 900 with an included angle larger than 90 degrees and smaller than 180 degrees according to the included angle between the longitudinal rib 920 and the inner rotating rod 210 on the steel bar 900.
For small angle rebar 900:
the driving motor 301 is started, the driving gear 302 rotates, at this time, the driving gear 302 is meshed with the first linear rack 311 to drive the reversing slider 310 to move forward, oil in the piston cavity of the first driving cylinder 330 decreases, oil in the driving cavity increases to drive the outer rotating disc 220 to rotate clockwise, and the outer rotating disc 220 drives the inner rotating disc 210 to rotate clockwise by using a first friction force. After rotating a certain angle (less than 90 °), one end of the inner rotating rod 210 contacts the longitudinal rib 920, and at this time, the first friction is not enough to drive the reinforcing bars 900 to rotate, the inner rotating rod 210 cannot rotate continuously, and the outer rotating disc 220 rotates continuously, i.e., the inner rotating rod 210 and the outer rotating disc 220 rotate relatively.
When the inner rotating rod 210 rotates to the left end of the arc-shaped sliding groove 221: on one hand, the clamping block 223 is clamped in the arc-shaped sliding block 222 and presses the inner rotating rod 210 to move towards the direction of the steel bar 900, so that the steel bar 900 can be clamped by the inner rotating rod 210, and the clamping block 223 cannot be separated after being clamped in the arc-shaped sliding block 222; on the other hand, when the inner rotation rod 210 slides from the right end of the arc-shaped sliding groove 221 to the left end of the arc-shaped sliding groove 221, the inner rotation rod 210 and the outer rotation plate 220 relatively rotate, at this time, the volume change of the movable chamber reaches a certain value and the second driving cylinder 321 is actuated, so that the gear teeth on the reversing half-ring gear 320 extend out, at this time, the driving gear 302 and the reversing half-ring gear 320 are engaged, disengaged from the first linear gear, and gradually move to be engaged with the second linear gear, thereby completing the reversing.
After the direction is changed, the outer rotating plate 220 rotates counterclockwise, and at this time, the inner rotating plate 210 and the reinforcing bar 900 remain fixed and do not rotate because the first friction between the inner rotating plate 210 and the outer rotating plate 220 is not enough to drive the reinforcing bar 900. After the outer rotating disc 220 rotates by a certain angle, the inner rotating rod 210 rotates to the right end of the arc-shaped sliding groove 221, the inner rotating rod 210 is driven to rotate under the pushing action of the outer rotating disc 220 until the inner rotating rod 210 rotates to the initial position, and the driving steel bar 900 is rotated synchronously in the process. When interior dwang 210 rotates to initial position, reset fixture block 113 pushes away reset rod 224, and reset rod 224 is ejecting from arc slider 222 with joint piece 223, and joint piece 223 resets under the effect of elastic coiling rope 225, and interior dwang 210 loosens reinforcing bar 900. At this time, the position of the longitudinal rib 920 of the reinforcing bar 900 is the right adjacent position of the rotary bar 210 in the initial state, and thus the position of the longitudinal rib 920 of the reinforcing bar 900 can be determined.
For large angle rebar 900:
the driving motor 301 is started, the driving gear 302 rotates, at this time, the driving gear 302 is meshed with the first linear rack 311 to drive the reversing slider 310 to move forward, oil in the piston cavity of the first driving cylinder 330 decreases, oil in the driving cavity increases to drive the outer rotating disc 220 to rotate clockwise, and the outer rotating disc 220 drives the inner rotating disc 210 to rotate clockwise by using a first friction force. After rotating a certain angle (greater than 90 °), one end of the inner rotating rod 210 contacts the longitudinal rib 920, and at this time, the first friction is not enough to drive the reinforcing bars 900 to rotate, the inner rotating rod 210 cannot rotate continuously, and the outer rotating disk 220 rotates continuously, i.e., the inner rotating rod 210 and the outer rotating disk 220 rotate relatively.
When the inner rotary rod 210 rotates to the left end of the arc-shaped sliding groove 221, and the inner rotary rod 210 slides from the right end of the arc-shaped sliding groove 221 to the left end of the arc-shaped sliding groove 221, the inner rotary rod 210 and the outer rotary plate 220 have relatively large relative rotation, at this time, the volume change of the movable chamber reaches a certain value and the second driving cylinder 321 is driven to act, but because the trigger block is separated from the trigger groove 315 at this time, the movable chamber and the second driving cylinder 321 are not communicated, the second driving cylinder 321 cannot act, gear teeth on the reversing half gear cannot extend out, and the reversing half gear cannot be used for reversing in advance.
The outer rotating disk 220 continues to rotate until the driving gear 302 goes through the first arc rack 311 and enters the first arc rack 312 for reversing. Furthermore, during the continuous rotation of the outer rotating disk 220, the inner rotating rod 210 rotates 180 ° from the initial position of the upper side to the initial position of the lower inner rotating rod 210, and since the longitudinal ribs 920 on the reinforcing bars 900 are symmetrical, the position of the longitudinal rib 920 on the reinforcing bar 900 can be considered as the right side adjacent position of the rotating rod 210 in the initial state, thereby completing the positioning of the longitudinal rib 920 of the reinforcing bar 900.
It should be noted that the transportation assembly 500 grabs the reinforcing bar 900 from the sensing clamping assembly 200 at the time when the inner rotation lever 210 is at the upper initial position or the lower initial position and the outer rotation plate 220 is at the upper initial position or the lower initial position.
All possible combinations of the technical features in the above embodiments may not be described for the sake of brevity, but should be considered as being within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the invention, and these changes and modifications are all within the scope of the invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
