[0001] The invention belongs to the technical field of plate stacking, in particular to a plate stacking unloading device. Background Art

[0002] Calcium silicate board is a new generation of "green" building materials. It has unique environmental protection functions based on excellent moisture-proof and fire-proof properties. Calcium silicate board is a new type of building material that uses silicon powder and calcium powder as the main base material, natural wood fiber as the reinforcing material, and other auxiliary materials as the external additives. It is formed by slurry flow and then cured at high temperature and high pressure.

[0003] After the calcium silicate board is produced and formed, it is necessary to remove the formed boards from the assembly line and neatly stack them on pallets to facilitate subsequent transfer and transportation.

[0004] Since some dust and particles will remain on the surface of the calcium silicate board during the production process, when the suction cup is used to adsorb and fix the calcium silicate board, the dust and particles will have an adverse effect on the adsorption and fixation of the suction cup, and long-term use will cause the dust and particles to enter the pipeline, causing the pipeline to be blocked, affecting the normal use of the suction cup. At the same time, when the existing unloading mechanism unloads the calcium silicate board, the calcium silicate board is prone to position deviation, affecting the neatness of the unloading mechanism when stacking the calcium silicate board, and further affecting the subsequent packaging, transshipment and transportation of the calcium silicate board. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] like Figures 1 to 10 As shown, a plate stacking unloading device described in the present invention comprises a gantry 1, a slide rail 11 is installed on the gantry 1, a slider plate 12 is installed on the slide rail 11, the slider plate 12 moves on the slide rail 11 through a transverse motor 13, a lifting rod 15 is slidably installed on the slider plate 12, the lifting rod 15 moves in the vertical direction through a vertical motor 14, and a grabbing mechanism 2 is installed at the lower end of the lifting rod 15, and the grabbing mechanism 2 grabs the calcium silicate board 3; The gripping mechanism 2 includes a mounting frame 21, a fixing frame 4 is mounted on the mounting frame 21, a suction cup 41 is mounted on the fixing frame 4 via a spring support rod 411, a connecting block 412 is mounted on the suction cup 41, the spring support rod 411 and the connecting block 412 are connected to each other, a hose 421 is mounted in the suction cup 41, the hose 421 is connected to the air pipe on the suction cup 41, and a blowing ring 42 is mounted at the lower end of the hose 421; The mounting frame 21 is provided with a clamping cylinder 51, and the clamping cylinder 51 is provided with a blocking plate 5, the lower end surface of the blocking plate 5 and the lower end surface of the suction cup 41 are in the same plane, and the blocking plate 5 blocks and clamps the edge of the calcium silicate board 3; During operation, the unloading equipment is installed at the end of the calcium silicate board 3 production line, and the calcium silicate board 3 formed on the production line is removed from the assembly line by the unloading equipment, and the removed calcium silicate board 3 is stacked on the pallet, waiting for subsequent transfer and transportation. At the same time, the calcium silicate board 3 on the assembly line is unloaded by the unloading equipment, so as to avoid the situation that the calcium silicate board 3 is transported to the destination by the assembly line before the improvement, and then the calcium silicate board 3 is directly dropped from the assembly line onto the pallet, which will generate huge noise, damage the board, and the position of the board stacking is offset; At the same time, since there will be some dust and particles on the surface of the calcium silicate board 3 after production and molding, when the suction cup 41 is used to adsorb and fix the calcium silicate board 3 for grabbing, the dust and particles on the surface of the calcium silicate board 3 are likely to affect the adsorption and fixing effect of the suction cup 41 and easily cause excessive dust and particles to enter the suction cup 41, resulting in pipeline blockage. Therefore, an air blowing ring 42 is installed in the suction cup 41. When the grabbing mechanism 2 moves to the top of the calcium silicate board 3 and the suction cup 41 contacts the calcium silicate board 3, the controller controls the external air source to first deliver a positive airflow to the suction cup 41, so that the airflow enters the air blowing ring 42. The air is blown out from the air holes on the blowing ring 42, so that the blowing ring 42, which is also in contact with the surface of the calcium silicate board 3, blows the area to be adsorbed by the suction cup 41 to remove the dust and particles on the calcium silicate board 3. After that, the controller controls the external air source to deliver a negative pressure airflow to the suction cup 41, so that a negative pressure is generated at the suction cup 41, and the calcium silicate board 3 is adsorbed and fixed, thereby avoiding the dust and particles remaining on the surface of the calcium silicate board 3 during the production process from affecting the adsorption and fixation of the suction cup 41, and avoiding the dust and particles from entering the suction cup 41 and the pipeline, causing the suction cup 41 and the pipeline to be blocked, affecting the normal use of the unloading equipment; At the same time, after the suction cup 41 adsorbs and fixes the calcium silicate board 3, the controller controls the clamping cylinder 51 to work, thereby driving the blocking plate 5 to move toward the calcium silicate board 3, so that the blocking plate 5 and the side of the calcium silicate board 3 are in contact with each other, and then the blocking plate 5 clamps and fixes the calcium silicate board 3, thereby preventing the calcium silicate board 3 from sliding or falling when the grasping mechanism 2 transfers the calcium silicate board 3; At the same time, when the suction cup 41 adsorbs and fixes the calcium silicate board 3, the suction cup 41 will be deformed and the calcium silicate board 3 will move upward relative to the grasping mechanism 2. At this time, after the calcium silicate board 3 moves upward, the lower surface of the calcium silicate board 3 will be located above the lower surface of the blocking plate 5, thereby preventing the edge of the calcium silicate board 3 from being damaged when the blocking plate 5 clamps and fixes the calcium silicate board 3. At the same time, since the blocking plate 5 will be installed around the calcium silicate board 3, the blocking plate 5 will limit the position of the calcium silicate board 3, thereby preventing the calcium silicate board 3 from shaking and deflecting during the transfer process, thereby ensuring that the unloading equipment stacks the calcium silicate board 3 neatly and avoiding excessive deflection.

[0020] As an embodiment of the present invention, a mounting block 43 is mounted on the connecting block 412, the mounting block 43 is hollow inside, the space inside the mounting block 43 is connected to the air pipe on the suction cup 41, a through hole 431 is opened on the mounting block 43, an elastic sheet 432 is mounted on the through hole 431, and the through hole 431 is connected to the space inside the suction cup 41; The air blowing ring 42 is connected to the space in the mounting block 43 through a hose 421, and a return spring is installed in the hose 421; When the suction cup 41 contacts the surface of the calcium silicate board 3 and the external air source delivers positive pressure gas under the control of the controller, the positive pressure gas delivered by the external air source will enter the mounting block 43. At this time, the elastic sheet 432 and the through hole 431 in the mounting block 43 will be closed under the action of the positive pressure, so that the positive pressure gas enters the blowing ring 42 from the hose 421 to purge the surface of the calcium silicate board 3, and clean up the floating dust and particles on the surface of the calcium silicate board 3, so as to avoid affecting the suction cup 41 to adsorb and fix the calcium silicate board 3. At the same time, all the positive pressure gas is ejected from the blowing ring 42 to ensure the ejected air flow speed and air volume, so as to improve the cleaning effect of floating dust and particles, and avoid the positive pressure gas being divided into two parts: one part is ejected from the blowing ring 42, and the other part enters the suction cup 41 and disperses from the edge of the suction cup 41, so as to avoid affecting the cleaning effect of floating dust and particles in the area to be adsorbed by the suction cup 41; At the same time, when the external gas source delivers negative pressure gas under the control of the controller, the elastic sheet 432 and the through hole 431 in the mounting block 43 will open under the negative pressure, so as to generate negative pressure in the suction cup 41, so that the suction cup 41 can adsorb and fix the calcium silicate board 3, avoiding that only the blowing ring 42 provides negative pressure in the suction cup 41, which affects the fixing effect of the suction cup 41; At the same time, by installing a return spring in the hose 421, the hose 421 can maintain a relatively fixed shape, so that the blowing ring 42 always stays in the middle position of the suction cup 41, thereby ensuring the blowing effect when blowing the dust and particles on the surface of the calcium silicate board 3, thereby preventing the blowing ring 42 from tilting or deviating in the suction cup 41 or sliding out of the suction cup 41 after long-term use, affecting the normal use of the suction cup 41 and the blowing of dust and particles on the surface of the calcium silicate board 3 before the suction cup 41 works.

[0021] As an embodiment of the present invention, an elastic layer 52 is provided on the surface of the blocking plate 5, and grooves are provided on the surface of the elastic layer 52; The elastic layer 52 is provided to provide a buffer when the clamping cylinder 51 drives the blocking plate 5 to clamp and fix the side of the calcium silicate board 3, thereby preventing the blocking plate 5 from directly forcibly squeezing the calcium silicate board 3, causing damage to the side of the calcium silicate board 3. At the same time, when the clamping cylinder 51 drives the blocking plate 5 and the elastic layer 52 to clamp and fix the calcium silicate board 3, the grooves on the surface of the elastic layer 52 are used to increase the friction between the blocking plate 5 and the calcium silicate board 3, thereby improving the fixing effect of the calcium silicate board 3, thereby preventing the edge of the calcium silicate board 3 from shaking or swaying during transfer after the suction cup 41 adsorbs and fixes the calcium silicate board 3, thereby preventing hidden cracks and damage inside the calcium silicate board 3.

[0022] As an embodiment of the present invention, a mounting groove is provided on the blocking plate 5, the opening of the mounting groove faces the side of the calcium silicate board 3, and a protruding bag 53 is installed in the mounting groove, and the protruding bag 53 protrudes below the lower surface of the calcium silicate board 3 after being inflated; At the same time, after the blocking plate 5 clamps and fixes the calcium silicate board 3, the external air source delivers positive pressure gas to the extending bag 53 under the control of the controller, so that the extending bag 53 is inflated, and at the same time, the extending bag 53 is extended from the installation groove, and the protruding part of the extending bag 53 will extend below the lower surface of the calcium silicate board 3, so that the extended extending bag 53 and the blocking plate 5 form an L shape, further fixing and supporting the calcium silicate board 3, and avoiding relative movement between the calcium silicate board 3 and the blocking plate 5 during the transfer process as much as possible, and the calcium silicate board 3 falling during the transfer process, which affects the normal use of the blanking equipment; At the same time, since the protruding portion of the extending capsule 53 will extend below the calcium silicate board 3, when the unloading equipment transfers the calcium silicate board 3 to the specified position and stacks it, the protruding portion on the extending capsule 53 will first contact the pallet, thereby preventing the calcium silicate board 3 from directly contacting and falling onto the pallet for stacking, that is, buffering the calcium silicate board 3 when stacking, avoiding collision between the calcium silicate board 3 and the pallet, resulting in noise and damage to the calcium silicate board 3.

[0023] As an embodiment of the present invention, the upper end of the elastic layer 52 is a fixed end 522, and the fixed end 522 is fixedly mounted on the blocking plate 5, and the lower end of the elastic layer 52 is a movable end 523, and the movable end 523 is in contact with the surface of the blocking plate 5; The opening of the mounting slot is blocked by the movable end 523; Since the lower end of the elastic layer 52 is the movable end 523, after the extension capsule 53 is inflated, the protruding portion of the extension capsule 53 will drive the movable end 523 of the elastic layer 52 to move together, and then the protruding portion of the extension capsule 53 and the movable end 523 will reach the lower surface of the calcium silicate board 3 together, so that the extension capsule 53 will not directly contact the calcium silicate board 3, avoiding excessive wear of the extension capsule 53 and affecting the service life of the extension capsule 53; At the same time, after the extended capsule 53 and the free end contact the calcium silicate board 3, the movable end 523 of the elastic layer 52 will be tightly squeezed onto the calcium silicate board 3, increasing the friction between the extended capsule 53, the free end and the calcium silicate board 3, and further improving the fixing effect of the calcium silicate board 3.

[0024] As an embodiment of the present invention, magnetic blocks 521 are installed at the lower ends of the elastic layer 52 and the blocking plate 5, and the magnetic blocks 521 attract each other; By installing magnetic blocks 521 on the elastic layer 52 and the blocking plate 5, after the protruding part of the protruding capsule 53 is retracted into the installation groove, the movable end 523 on the elastic layer 52 will be re-attached to the blocking plate 5, and then, under the mutual attraction between the magnetic blocks 521, the elastic layer 52 will be tightly attached to the blocking plate 5, avoiding curling, warping and distortion of the elastic layer 52, resulting in the elastic layer 52 being unable to buffer the contact between the blocking plate 5 and the calcium silicate board 3. At the same time, it can also ensure that the elastic layer 52 is always attached to the blocking plate 5, ensuring the shielding of the protruding part of the protruding capsule 53 and the protection of the protruding capsule 53.

[0025] As an embodiment of the present invention, a reinforcing rope 524 is provided in the elastic layer 52, and a rope knot is provided on the surface of the reinforcing rope 524; By installing a reinforcing rope 524 in the elastic layer 52, the strength of the elastic layer 52 is improved. After the extended bag 53 protrudes below the calcium silicate board 3, the elastic layer 52 as a whole is used to support the calcium silicate board 3, thereby further improving the fixing effect of the calcium silicate board 3 and avoiding the calcium silicate board 3 being affected by gravity, vibration or other factors during the transfer process, resulting in a tendency to shake, causing the elastic layer 52 to be damaged after being pulled, thereby affecting the service life of the elastic layer 52.

[0026] As an embodiment of the present invention, the lower surface of the calcium silicate board 3 is located between the upper surface and the lower surface of the extended capsule 53; The suction cup 41 has good elasticity; each of the protruding capsules 53 is connected to each other; After the extended capsule 53 is inflated, the upper part of the protruding part of the extended capsule 53 will be aligned with the side of the calcium silicate board 3, and the lower part of the protruding part of the extended capsule 53 will protrude below the lower surface of the calcium silicate board 3. In this process, the part of the protruding part of the extended capsule 53 that contacts the calcium silicate board 3 will push and squeeze the calcium silicate board 3. Since the suction cup 41 has good elasticity, after the grasping mechanism 2 adsorbs and fixes the calcium silicate board 3 and picks it up, the pushing and squeezing of the side of the calcium silicate board 3 by the extended capsule 53 will make the calcium silicate board 3 reach the middle position of the grasping mechanism 2, ensuring that the calcium silicate board 3 can be in the same position of the grasping mechanism 2 each time the grasping mechanism 2 picks up the calcium silicate board 3, that is, the calcium silicate board 3 can be accurately positioned when grasping, thereby ensuring that the calcium silicate boards 3 can be stacked neatly when they are stacked, avoiding deviations of the calcium silicate boards 3 after stacking.

[0027] The specific workflow is as follows: During operation, the unloading equipment is installed at the end of the calcium silicate board 3 production line, and the calcium silicate board 3 formed on the production line is removed from the assembly line by the unloading equipment, and the removed calcium silicate board 3 is stacked on a pallet, waiting for subsequent transfer and transportation; At the same time, a blowing ring 42 is installed in the suction cup 41. When the grasping mechanism 2 moves to the top of the calcium silicate board 3 and the suction cup 41 contacts the calcium silicate board 3, the controller controls the external air source to first deliver a positive airflow to the suction cup 41, so that the airflow enters the blowing ring 42 and is ejected from the air holes on the blowing ring 42, so that the blowing ring 42, which also contacts the surface of the calcium silicate board 3, purges the area to be adsorbed by the suction cup 41. After that, the controller controls the external air source to deliver a negative pressure airflow to the suction cup 41, so that a negative pressure is generated at the suction cup 41, and the calcium silicate board 3 is adsorbed and fixed; At the same time, after the suction cup 41 adsorbs and fixes the calcium silicate board 3, the controller controls the clamping cylinder 51 to work, thereby driving the blocking plate 5 to move toward the calcium silicate board 3 to clamp and fix the calcium silicate board 3; At the same time, when the suction cup 41 adsorbs and fixes the calcium silicate board 3, the suction cup 41 will be deformed, and the calcium silicate board 3 will move upward relative to the grasping mechanism 2. At this time, after the calcium silicate board 3 moves upward, the lower surface of the calcium silicate board 3 will be located above the lower surface of the blocking plate 5; When the suction cup 41 contacts the surface of the calcium silicate board 3 and the external air source delivers positive pressure gas under the control of the controller, the positive pressure gas delivered by the external air source will enter the mounting block 43. At this time, the elastic sheet 432 and the through hole 431 in the mounting block 43 will be closed under the action of the positive pressure, so that the positive pressure gas enters the blowing ring 42 from the hose 421 to purge the surface of the calcium silicate board 3. At the same time, when the external gas source delivers negative pressure gas under the control of the controller, the elastic sheet 432 and the through hole 431 in the mounting block 43 will open under the negative pressure, so as to generate negative pressure in the suction cup 41, so that the suction cup 41 can adsorb and fix the calcium silicate board 3; At the same time, by installing a return spring in the hose 421, the hose 421 can maintain a relatively fixed shape, so that the blowing ring 42 always stays in the middle position of the suction cup 41; The elastic layer 52 is provided to provide a buffer when the clamping cylinder 51 drives the blocking plate 5 to clamp and fix the side of the calcium silicate board 3. At the same time, the grooves on the surface of the elastic layer 52 increase the friction between the blocking plate 5 and the calcium silicate board 3, thereby improving the fixing effect of the calcium silicate board 3. At the same time, after the blocking plate 5 clamps and fixes the calcium silicate board 3, the external air source delivers positive pressure gas to the extension bag 53 under the control of the controller, so that the extension bag 53 is inflated, and at the same time, the extension bag 53 is extended from the installation groove, and the protruding part of the extension bag 53 is extended below the lower surface of the calcium silicate board 3, so that the extended extension bag 53 and the blocking plate 5 form an L shape, and the calcium silicate board 3 is further fixed and supported; At the same time, since the protruding portion of the extended capsule 53 will extend below the calcium silicate board 3, when the unloading equipment transfers the calcium silicate board 3 to the designated position and stacks it, the protruding portion of the extended capsule 53 will first contact the pallet, thereby preventing the calcium silicate board 3 from directly contacting and falling onto the pallet for stacking, that is, buffering the calcium silicate board 3 when stacking; Since the lower end of the elastic layer 52 is the movable end 523, after the extension capsule 53 is inflated, the protruding portion of the extension capsule 53 will drive the movable end 523 of the elastic layer 52 to move together, and then the protruding portion of the extension capsule 53 and the movable end 523 will reach the lower surface of the calcium silicate board 3 together, so that the extension capsule 53 will not directly contact the calcium silicate board 3, and the extension capsule 53 will be prevented from being excessively worn; At the same time, after the extended capsule 53 and the free end contact the calcium silicate board 3, the movable end 523 of the elastic layer 52 will be tightly pressed onto the calcium silicate board 3, increasing the friction between the extended capsule 53, the free end and the calcium silicate board 3; By installing the magnetic blocks 521 on the elastic layer 52 and the blocking plate 5, after the protruding portion of the extended capsule 53 is retracted into the installation groove, the movable end 523 on the elastic layer 52 will be reattached to the blocking plate 5, and then, under the mutual attraction between the magnetic blocks 521, the elastic layer 52 will be closely attached to the blocking plate 5, thereby preventing the elastic layer 52 from curling, warping and distortion; By installing a reinforcing rope 524 in the elastic layer 52, the strength of the elastic layer 52 is improved, so that after the extended capsule 53 protrudes below the calcium silicate board 3, the elastic layer 52 as a whole is used to support the calcium silicate board 3; After the extended capsule 53 is inflated, the upper part of the protruding part of the extended capsule 53 will be aligned with the side of the calcium silicate board 3, and the lower part of the protruding part of the extended capsule 53 will protrude below the lower surface of the calcium silicate board 3. In this process, the part of the protruding part of the extended capsule 53 that contacts the calcium silicate board 3 will push and squeeze the calcium silicate board 3. Since the suction cup 41 has good elasticity, after the grasping mechanism 2 adsorbs and fixes the calcium silicate board 3 and picks it up, the pushing and squeezing of the side of the calcium silicate board 3 by the extended capsule 53 will make the calcium silicate board 3 reach the middle position of the grasping mechanism 2, ensuring that the calcium silicate board 3 can be in the same position of the grasping mechanism 2 each time the grasping mechanism 2 picks up the calcium silicate board 3, that is, the calcium silicate board 3 can be accurately positioned when grasping, thereby ensuring that the calcium silicate boards 3 can be stacked neatly when they are stacked, avoiding deviations of the calcium silicate boards 3 after stacking.
