The gantry manipulator includes two supporting beams and a connecting beam, and also includes a plurality of supporting columns. The connecting beam is provided with a first slider for guiding movement, the connecting beam is provided with a first driving device, the supporting beam is provided with a second driving device, the first slider is provided with a mounting frame that can slide in the up and down directions, a third driving device is provided between the mounting frame and the first slider, and a suction cup assembly is provided at the lower part of the mounting frame, the suction cup assembly includes a plurality of suction cup units that can grasp independently, and the suction cup unit includes a plurality of suction cups arranged in a matrix. By providing a plurality of suction cup units that can grasp independently, it is possible to grasp large materials such as plates, and also to grasp scattered materials. This expands the scope of application of the manipulator and improves the versatility of the manipulator's handling; In the actual operation process, due to the natural floating dust attached to the surface of the stone slab material, it will continue to rub and adhere to the adsorption contact surface of the negative pressure suction plate during repeated grabbing operations. In the long run, the accumulation of floating dust will inevitably weaken the adsorption efficiency of the negative pressure suction plate, and then cause the problem of unstable material grabbing, which will have a negative impact on production stability.

[0006] To achieve the above object, the present invention provides the following technical solutions: The invention discloses a gantry type automatic loading and unloading device and method for stone plates, comprising a gantry frame, wherein first electric guide rails are symmetrically fixedly connected to the left and right sides of the upper end of the gantry frame, second electric guide rails are installed at the output ends of the two first electric guide rails, a clamping piece is provided at the output end of the second electric guide rail, a mechanical driving arm is installed at the inner end of the clamping piece, a negative pressure suction plate is installed at the lower end of the mechanical driving arm, an electric conveyor belt is provided at the left side of the lower end of the gantry frame, a storage table is provided at the right side of the lower end of the gantry frame, and the storage table A plurality of stone slab material bodies are stacked at the upper end of the gantry frame, a middle base is provided at the lower end of the gantry frame, the middle base is located between the storage table and the electric conveyor belt, the upper end of the middle base is fixedly connected with a bottom support plate, the upper end of the bottom support plate is connected with a floating ash processing frame, a plurality of flexible roller members are provided on the left side of the upper end of the floating ash processing frame, the plurality of flexible roller members are equidistantly arranged from left to right, a sweeping inner plate is provided on the lower inner wall of the floating ash processing frame, and the sweeping inner plate is located on the right side of the flexible roller member.

[0007] In a further embodiment, the lower end of the negative pressure suction plate cooperates with the flexible roller member and the sweeping inner plate, and the lower inner wall of the floating dust processing frame is fixedly connected with a bottom sheet.

[0008] In a further embodiment, a plurality of sharp-angled anti-scraping strips are fixedly connected to the upper end of the bottom sheet, and the plurality of sharp-angled anti-scraping strips are equidistantly arranged from left to right.

[0009] In a further embodiment, the bottom sheet is located directly below the plurality of flexible roller members, and the plurality of pointed anti-scraping strips are in contact with the outer side walls of the flexible roller members.

[0010] In a further embodiment, a plurality of elastic connectors are fixedly connected to the upper end of the bottom support plate, and the plurality of elastic connectors are interconnected with the lower inner wall of the floating dust processing frame.

[0011] In a further embodiment, the outer side wall of the flexible roller member is connected to a replaceable outer layer, and the replaceable outer layer is a replaceable consumable.

[0012] In a further embodiment, the replaceable outer layer contacts the lower end of the negative pressure suction plate, and the upper sides of the flexible roller member and the sweeping inner plate slightly protrude from the floating dust processing frame.

[0013] In a further embodiment, a supporting load-bearing foot is fixedly connected to the lower end of the gantry frame, and the multiple supporting load-bearing foots are respectively distributed in a rectangular shape below the gantry frame.

[0014] In a further embodiment, the stone slab material body is transferred to the top of the electric conveyor belt through a negative pressure suction plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: First, in the present invention, by arranging a middle base on the conventional displacement route of the negative pressure suction plate, the floating dust processing frame it carries is precisely aligned with the return path of the negative pressure suction plate. When the negative pressure suction plate completes discharging on the electric conveyor belt, it immediately translates to the right to start the floating dust cleaning process. The operating surface of the negative pressure suction plate after translation first contacts a plurality of flexible roller members arranged at equal intervals. The replaceable outer surface of the outer wall of the flexible roller member uses its own good friction characteristics to gradually scrape the floating dust contaminated by the negative pressure suction plate due to grabbing the stone plate, and preliminarily removes large-area floating dust contamination. Then the negative pressure suction plate continues to displace and interact with the sweeping inner plate. Relying on the fine structure of the sweeping inner plate, the floating dust remaining in the subtle parts of the negative pressure suction plate is deeply cleaned, thereby achieving comprehensive and in-depth removal of the attachments to the negative pressure suction plate, effectively ensuring that the loading and unloading process will not be hindered by the floating dust problem, and always maintaining continuity and stability.

[0016] Secondly, in the present invention, the components inside the floating ash processing frame are connected to the bottom support plate through elastic connectors. During the operation of the equipment, the elastic connectors can dynamically and adaptively adjust the contact pressure between the floating ash processing frame and the negative pressure suction plate according to actual working conditions, such as the weight of the stone slab, the transportation speed, the degree of floating ash accumulation and other factors, to ensure that the floating ash cleaning effect is always in the best state.

[0017] Third, in the present invention, through the bottom sheet located below the flexible roller member and the multiple sharp-angle reverse scraping strips evenly distributed on it, the outer wall of the flexible roller member is always closely attached during the continuous operation of the equipment, and with the help of the mechanical scraping principle, the floating dust on the rotating flexible roller member is forced to detach in the opposite direction, so that the flexible roller member is kept clean at all times, thereby ensuring its efficient operation in the entire work process and continuously providing reliable floating dust cleaning services for the negative pressure suction plate.

[0018] Fourthly, in the present invention, the floating dust separated by reverse processing will be gathered in the grid plate area below the floating dust processing frame under the action of gravity and airflow. At this time, the external suction pump is started in time to generate negative pressure to draw the floating dust out of the processing frame, thereby preventing the cleaned floating dust from re-suspending and polluting the internal environment of the equipment, thereby realizing one-way effective removal of floating dust.

[0019] The gantry type automatic loading and unloading device and method for stone slabs includes the following loading and unloading steps: S1: Loading preparation, the negative pressure suction plate is located at the initial position above the storage table, and the electric conveyor belt is in standby state.

[0020] S2: Grabbing of stone slabs. According to the preset program, the first electric guide rail and the second electric guide rail are precisely controlled to work together, driving the mechanical drive arm to move quickly and smoothly to the precise position above the storage table and align with the topmost stone slab material body stacked on the storage table. Then the negative pressure device is started, and the strong suction force generated by the negative pressure suction plate is used to firmly adsorb the stone slab material body and successfully grab it from the storage table.

[0021] S3: Stone slab transportation. After the grabbing is completed, the mechanical drive arm carries the stone slab material body strictly along the preset trajectory until it reaches the designated drop point above the electric conveyor belt.

[0022] S4: Cleaning of floating dust. The stone slab material body is accurately placed on the electric conveyor belt. After the electric conveyor belt is started to transport the stone slab away, the mechanical driving arm drives the negative pressure suction plate on the reset path to return to the initial position above the storage table, passing above the floating dust processing frame, and controls the mechanical driving arm to move horizontally to the right, so that the operating surface of the negative pressure suction plate first contacts with multiple flexible roller parts, and gradually wipes off the floating dust on the negative pressure suction plate due to grabbing the stone slab. Then the negative pressure suction plate continues to move and contacts with the sweeping inner plate. The sweeping inner plate further cleans the floating dust in the fine parts with its fine bristle structure. At the same time, multiple sharp-angled anti-scraping strips on the bottom sheet are constantly in contact with the flexible roller part, and the floating dust on the rotating flexible roller part is reversely scraped to ensure the cleanliness of the flexible roller part. The cleaned floating dust is sucked away in time by the external suction pump through the grid plate under the floating dust processing frame.

[0023] S5: Reset standby. After completing the floating dust cleaning operation, the mechanical drive arm drives the negative pressure suction plate to continue returning to the initial position above the storage table along the original path, waiting for the next grabbing and loading operation instruction to start a new cycle operation process.
