[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0028] Example 1

[0029] like Figures 1 to 4 As shown, the automatic unloading equipment includes a feeding track, a unloading mechanism is arranged above the feeding track, the unloading mechanism includes a stacking rack, relative X-position notches and relative Y-position notches are arranged on the circumference of the stacking rack, a grabbing component is arranged at the X-position notch, a dividing component is arranged at the Y-position notch, a carrier in position sensor 13 is arranged at the bottom of the stacking rack, and a material sensor is arranged at the Y-position notch of the stacking rack.

[0030] like Figure 1 and 2 As shown, the feed track includes a frame, on which a feed motor 1 and two parallel conveyor rails are mounted. The conveyor rails include several pulleys 2, each of which has a tensioned belt 3 around its outer circumference. The feed motor 1's rotating shaft is fixedly connected to one of the pulleys 2, and a baffle 4 is provided on the outer side of the belt 3. When the feed motor 1 is started, it rotates in a certain direction, driving the pulleys 2 to rotate in a certain direction. Friction causes the belt 3 and the other pulleys 2 to rotate in a certain direction, thereby transporting the carrier.

[0031] A material stop assembly is located between the two conveyor rails. It includes a stand mounted with a stop cylinder 5, which extends and retracts a stop block upward. When the carrier is detected to be directly below the unloading mechanism, the stop cylinder 5 is activated to raise the block, blocking the carrier's advance. Once the unloading process is complete, the stop cylinder 5 is activated to lower the block, releasing the carrier to continue its advance.

[0032] like Figure 3 As shown, the stacking rack includes four bases 6 arranged in a matrix. Angle steels 7 are fixed upright on the inner sides of the bases 6. The four angle steels 7 surround a stacking area, with X-notches or Y-notches formed between adjacent angle steels 7. The height of the angle steels 7 determines the stacking height of the materials. Several beading strips or cover plates are stacked and placed in the stacking area, with their corners aligned against the right angles of the angle steels 7 to ensure neat positioning. Part of the side edges of the beading strips or cover plates are exposed through the X-notches or Y-notches.

[0033] The baffle 4 is a half frame with an inner side open, and the base 6 is a right-angle seat, the horizontal side of the right-angle seat is fixed on the top surface of the half frame.

[0034] like Figures 3 to 4As shown, the material handling assembly includes an X-mounting plate, the two side edges of which are fixedly connected to the right-angled edges of two adjacent angle steels 7. A lifting cylinder 8 is provided on the X-mounting plate and fixedly mounted on the outer surface of the X-mounting plate. By making full use of the X-position gap and rationally arranging the X-mounting plate, the installation of other components can be achieved without hindering the material handling operation.

[0035] Lifting cylinder 8 extends a lifting rod downward, the bottom end of which is fixed to a mounting plate. A gripping cylinder 9 is fixed to the underside of the mounting plate. Grabbing cylinder 9 extends and retracts toward the X-notch, driving gripping claw 10. Lifting cylinder 8 is vertically positioned, while gripping cylinder 9 is horizontally positioned. Lifting cylinder 8 drives gripping cylinder 9 upward and downward, extending gripping claw 10 toward the stacking area. Grabbing claw 10 then supports all beading or cover panels above the correct position.

[0036] The material dividing assembly includes a Y mounting seat, both side edges of the Y mounting seat are respectively fixedly connected to the right-angled sides of two adjacent angle steels 7, and the Y mounting seat has a horizontal plate.

[0037] A pneumatic cylinder 11 is mounted on the Y-mounting base. It extends and retracts toward the Y-notch, driving a pneumatic claw 12. Pneumatic cylinder 11 is fixed horizontally at the pneumatic dispensing position. Pneumatic claw 12 extends from pneumatic cylinder 11 toward the stacking area, separating the lowest layer of beading or cover plate.

[0038] The material-distributing cylinder 11 is fixed to a horizontal plate. The material-distributing claw 12 is a Z-shaped claw with a top surface that slopes downward from the outside to the inside. By fully utilizing the Y-position notch and rationally arranging the Y mounting base, it allows for the installation of other components without hindering the material-distributing operation. The downwardly inclined surface of the Z-shaped claw facilitates insertion between stacked beading strips or cover plates, while also pressing down on lower-lying beading strips or cover plates to separate them.

[0039] The operation mode of this automatic unloading equipment is:

[0040] 1. Start the feeding track to directional and uniformly transport several carriers. When the carrier arrival sensor 13 detects that the carrier has moved to the bottom of the discharge mechanism, start the blocking cylinder 5 to raise the blocking block upwards to block the carrier from moving forward.

[0041] 2. Start the material separation cylinder 11 to extend the material separation claw 12 to the stacking area, and separate the lowest layer or cover plate from the other layer or cover plates above through the material separation claw 12 to form a separation gap.

[0042] 3. Then start the grabbing cylinder 9 to extend the grabbing claw 10 toward the stacking area, so that the grabbing claw 10 extends into the separation gap and supports all the above layering strips or cover plates through the grabbing claw 10. Start the dividing cylinder 11 to retract the dividing claw 12.

[0043] 4. Restart the lifting cylinder 8 to drive the grabbing cylinder 9 and the grabbing claw 10 to move downward, and simultaneously push the lowest layer or cover plate down to the carrier, while the remaining stacked layer or cover plates drop one position.

[0044] 5. After the material sensor detects a material unloading station, start the material blocking cylinder 5 to lower the blocking block, release the carrier and continue to move forward.
