A roll material handling method, applied to a warehouse control system in a roll material handling system according to any one of claims 1 to 7, characterized in that: The roll material handling method includes the roll material placing method and the roll material picking method. The roll material placing method is as follows: Step S1, in response to receiving a release command, executing a method for generating the size of a roll material, the method for generating the size of a roll material comprising: Sending a data collection instruction to the visual inspection mechanism so that the visual inspection mechanism can recognize the width and diameter data of the rolled material; Step S2: sending an initialization instruction to the pallet stacker (4) so that the pallet stacker (4) performs an initialization operation, and the pallet stacker (4) adjusts the fork spacing of the clamping mechanism to clamp the rolled material; Step S3: sending a roll material placing instruction to the pallet stacker (4), sending the center coordinate data of the position where the roll material is placed on the shelf (1) to the pallet stacker (4), so that the pallet stacker (4) executes the instruction and places the roll material at the designated position on the shelf (1); A method for picking up rolled materials comprises: a warehouse control system responds to receiving a picking command, the warehouse control system obtains the center coordinate information of the position where the rolled materials are stored on a shelf (1), sends the picking instruction to a pallet stacker (4), and the pallet stacker (4) executes the instruction and moves to a designated position on the shelf (1) to clamp the rolled materials.
9. The method for handling rolled materials according to claim 8, characterized in that: The algorithm for measuring and positioning the roll material of the visual inspection mechanism includes: During initialization, a detection reference plane is established with the plane of the material tray (6), and the outer edge is used as a reference reference line, and a detection space coordinate system is established based on this; Two binocular stereo vision cameras (11) at high or low positions obtain a point cloud of the shaft end on the material tray (6); Calculate the minimum circumscribed cuboid of the spatial point cloud above the detection reference plane; The width of the smallest circumscribed cuboid is the diameter of the rolled material, and the length of the smallest circumscribed cuboid is the width of the rolled material; The distance between the cuboid and the front edge and the distance between the cuboid and the left edge complete the positioning of the rolled material; The two binocular stereo vision cameras (11) at a high position are used to measure and position the rolled materials of a larger size, and the two binocular stereo vision cameras (11) at a low position are used to measure and position the rolled materials of a smaller size.
10. The method for handling rolled materials according to claim 8, characterized in that: Step S3 also includes: The warehouse control system sends the center coordinates of the position where the rolled material is placed on the shelf (1) to the control unit of the loading platform of the pallet stacker (4) and the control unit of the onboard cabinet. After receiving the center coordinate information of the position where the rolled material is placed on the shelf (1), the control unit of the loading platform of the pallet stacker (4) and the control unit of the onboard cabinet adjust the height through the lifting mechanism and move through the ground rail (4-1) to transport the rolled material on the clamping mechanism to the designated position on the shelf (1).
