When moving to the corresponding storage position, the loading platform is driven to rotate by the rotating assembly, so that the material on the surface of the loading platform is inclined. During the inclination of the loading platform, the limit assembly is driven to move in the opposite direction of clamping, so that the material limited in the limit assembly slides to the storage position. A unloading assembly is provided on one side of the loading platform close to the storage position. The unloading assembly is used to buffer the placed materials. At the same time, the unloading assembly is used to shovel and take out the materials placed at the storage position.

[0008] As a further improvement of the technical solution, a limiting beam is provided on the surface of the loading platform near the storage position, the limiting beam is used to limit the end of the material, and a rotating roller is provided at the bottom of the limiting beam.

[0009] As a further improvement of the present technical solution, the limiting assembly includes a column barrel arranged on both sides of the loading platform, a sliding column is slidably provided on the inner wall of the column barrel, a clamping plate is provided at the end of the sliding column, a first elastic member is provided between the column barrel and the sliding column, and the clamping plate is used to automatically clamp the material.

[0010] As a further improvement of the technical solution, symmetrical fixed blocks are provided on both sides of the surface of the movable platform, a collecting rod is rotatably provided on the surface of the fixed block, a torsion spring is provided between the collecting rod and the fixed block, a driven gear is provided at the end of the collecting rod, and a traction rope is provided at the end of the sliding column, and the traction rope passes through the column tube and is wrapped around the surface of the collecting rod.

[0011] As a further improvement of the technical solution, the traction force of the first elastic member on the traction rope is twice the traction force of the torsion spring on the traction rope.

[0012] As a further improvement of the present technical solution, the rotating assembly includes a cylinder arranged at the end of the moving platform, and the piston rod at the end of the cylinder drives the worktable to rotate on the surface of the moving platform. A driving gear is provided at the rotating shaft of the worktable, and the driving gear meshes and rotates with the driven gear.

[0013] As a further improvement of the technical solution, sliding rods are provided at the four corners between the movable platform and the loading platform, and a second elastic member is provided inside the sliding rods. The loading platform is supported by the sliding rods to reduce the load-bearing of the piston rod at the end of the cylinder on the loading platform.

[0014] As a further improvement of the present technical solution, the unloading assembly includes a groove arranged on the surface of the loading platform, a support rod is arranged at the groove, a shovel plate is rotatably arranged on the surface of the support rod, a third elastic member is arranged on the surface of the support rod, a shovel plate and a side wall of the groove are respectively connected on both sides of the third elastic member, and in a natural state, the shovel plate is subjected to the force of the third elastic member and forms an angle of 45° with the horizontal plane, and a cut angle is arranged at the bottom of the shovel plate, and the cut angle is parallel to the horizontal plane in the absence of external force.

[0015] The second object of the present invention is to provide a method for using a stacker for a stainless steel production stereoscopic warehouse, comprising the stacker for a stainless steel production stereoscopic warehouse as described in any one of the above, S1, placing materials on the surface of a loading platform, automatically limiting and fixing both sides of the materials by a limiting component, and driving the materials to move vertically to a corresponding storage position height by sliding a moving platform on the surface of a traction frame; S2. Start the motor to drive the gear body to rotate, drive the rack meshing with the surface of the gear body to move horizontally, move the loading platform to the inside of the storage position, drive the loading platform to rotate on the surface of the moving platform through the rotating component, release the limit fixation of the material by the limit component during the rotation of the loading platform, and make the material slide from the roller surface to the corresponding storage position; S3. When the material limited at the limit component slides down, a limit beam is set on the surface of the loading platform near the storage position to limit the height of the lifted material. At the same time, a rotating roller is set at the bottom of the limit beam. The rolling friction between the rotating roller and the material reduces the friction between the material and the limit beam, thereby avoiding the lifting of the material end and blocking it outside the storage position.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the process of placing materials, the stacker of the stainless steel production stereoscopic warehouse rotates the driving gear provided at the rotating shaft of the loading platform, and the driving gear drives the driven gear to mesh and rotate when rotating, so as to reel in the traction rope wrapped around the surface of the collecting rod, and the collecting rod twists the torsion spring during the rotation process, and at the same time, the pulling force of the traction rope pulls the sliding column, so that the sliding column squeezes the first elastic member, so that the external force on the material fixed between the clamping plates disappears, so that the material can quickly slide to the storage position, thereby improving the placement efficiency of the material.

[0017] 2. The stacker of the stainless steel production stereoscopic warehouse places the material between the clamping plates. The clamping plates are squeezed by the material to drive the sliding column to slide on the inner wall of the column tube, so that the first elastic member is deformed to exert a reaction force on the clamping plates to clamp and fix the material. Since the first elastic member has a buffering effect, the clamping plates can adaptively clamp according to the material size to improve the clamping efficiency. In addition, the clamping force of the clamping plates is small during the clamping process, and the material will not be squeezed and deformed, thereby protecting the material and reducing material loss.

[0018] 3. The stacker of the stainless steel production stereoscopic warehouse sets a limit beam on the surface of the loading platform near the storage position, and limits the height of the lifted material through the limit beam. At the same time, a rotating roller is set at the bottom of the limit beam. The rolling friction between the rotating roller and the material reduces the friction between the material and the limit beam, avoiding the lifted end of the material from being blocked outside the storage position, which is convenient for placing the material. At the same time, when taking the material, the end of the material is limited by the limit beam to avoid the lifted position of the material from shifting, causing the material to fall from a high altitude, avoiding the occurrence of safety hazards.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] One of the purposes of the present invention is to provide a stacker for a stainless steel production stereoscopic warehouse, Figure 1-Figure 8 As shown, it includes a traction frame 100 and a moving platform 101, a rack is provided at the bottom of the moving platform 101, a symmetrical motor 102 is provided on the side wall of the moving platform 101, a gear body 103 is provided at the end of the motor 102, and the gear body 103 is meshed and arranged at the bottom of the rack. When the gear body 103 rotates, it drives the rack to move in the horizontal direction, and a loading platform 200 is provided above the moving platform 101; A rotating assembly 400 is provided between the moving platform 101 and the loading platform 200. The rotating assembly 400 is used to drive the loading platform 200 to rotate in the horizontal direction. Symmetrical rollers 201 are provided on the surface of the loading platform 200, and symmetrical limiting assemblies 300 are provided on both sides of the loading platform 200. The limiting assemblies 300 are used to automatically limit the material. When moving to the corresponding storage position, the loading platform 200 is driven to rotate by the rotating assembly 400, so that the material on the surface of the loading platform 200 is inclined. During the inclination of the loading platform 200, the limiting assembly 300 is driven to move in the opposite direction of clamping, so that the material limited in the limiting assembly 300 slides to the storage position. A discharging assembly 500 is provided on one side of the loading platform 200 close to the storage position. The discharging assembly 500 is used to buffer the placed material. At the same time, the discharging assembly 500 is used to shovel and take the material placed at the storage position.

[0023] The improvement of the present invention lies in that: by placing the material between the clamping plates 303, the clamping plates 303 are squeezed by the material to drive the sliding column 302 to slide on the inner wall of the column tube 301, so that the first elastic member 304 is deformed to exert a reaction force on the clamping plates 303 to clamp and fix the material. Since the first elastic member 304 has a buffering effect, the clamping plates 303 can adaptively clamp according to the material size, thereby improving the clamping efficiency. In addition, during the clamping process, the clamping force of the clamping plates 303 is small, and the material will not be squeezed and deformed, thereby protecting the material and reducing material loss.

[0024] When the material is moved to the corresponding storage position by the moving platform 101 for placement or taking, when the material placed on the surface of the loading platform 200 is long, due to the limited height of the placement slot, in order to prevent the end of the material from being lifted up and blocked outside the storage position, affecting the placement of the material, the motor 102 is started to drive the gear body 103 to rotate, and the rack meshing with the surface of the gear body 103 is driven to move horizontally, so that the material limited to the limit assembly 300 slides down, and the material placed on the surface of the loading platform 200 near the storage position is placed on the rack 103. A limiting beam 202 is arranged to limit the height of the lifted material. Meanwhile, a rotating roller 203 is arranged at the bottom of the limiting beam 202. The rolling friction between the rotating roller 203 and the material can reduce the friction between the material and the limiting beam 202, thereby preventing the lifted end of the material from being blocked outside the storage position, thus facilitating the placement of the material. Meanwhile, when taking the material, the end of the material is limited by the limiting beam 202, thereby preventing the lifted position of the material from shifting, causing the material to fall from a high altitude, and thus avoiding the occurrence of safety hazards.

[0025] Considering that during the production of stainless steel materials, the surface of the materials is relatively smooth, during the storage of the materials, the materials are easy to slide during the movement, causing the materials to fall from the surface of the loading platform 200. In order to prevent the materials from falling, a clamping device is usually used to clamp the materials. During the clamping process, since the materials are of different sizes, in order to avoid deformation of the materials when clamping and fixing the materials, it is necessary to frequently adjust the clamping force according to the diameter of the materials, which is rather troublesome. Therefore, the limiting assembly 300 includes a column 301 arranged on both sides of the loading platform 200, and a sliding column 302 is slidably provided on the inner wall of the column 301, and a clamping plate 303 is provided at the end of the sliding column 302. A first elastic member 304 is provided between the column 301 and the slide 302, and the clamp 303 is used to automatically clamp the material. By placing the material between the clamps 303, the clamps 303 are squeezed by the material and drive the slide 302 to slide on the inner wall of the column 301, so that the first elastic member 304 is deformed to exert a reaction force on the clamp 303 to clamp and fix the material. Since the first elastic member 304 has a buffering effect, the clamp 303 can adaptively clamp according to the material size to improve the clamping efficiency. In addition, during the clamping process, the clamping force of the clamp 303 is small, and the material will not be squeezed and deformed, thereby protecting the material and reducing material loss.

[0026] When the materials clamped between the clamping plates 303 are moved to the corresponding storage position, when the loading platform 200 is tilted to make the materials slide down, the materials are clamped by the clamping force of the clamping plates 303, which makes it difficult for the materials to fall down, affecting the storage efficiency of the materials. Therefore, symmetrical fixed blocks are provided on both sides of the surface of the moving platform 101, and a collecting rod 306 is rotatably provided on the surface of the fixed block. A torsion spring 307 is provided between the collecting rod 306 and the fixed block. A driven gear 308 is provided at the end of the collecting rod 306, and a traction rope 305 is provided at the end of the sliding column 302. The traction rope 305 passes through the column 301 and is wound around the surface of the collecting rod 306. The collecting rod 306 is rotated to make the traction rope 305 fixed at the end of the sliding column 302 be wound around the surface of the collecting rod 306. The traction force of the first elastic member 304 on the traction rope 305 is twice that of the traction force of the torsion spring 307 on the traction rope 305. The traction force on the slide post 302 causes the slide post 302 to drive the clamping plate 303 to move away from the material surface, so that the clamping plate 303 stops limiting and fixing the material, which makes it easier for the material to slide quickly to the corresponding storage position for storage, thereby improving the storage efficiency of the material. At the same time, in order to prevent the torsion spring 307 from having too much traction on the traction rope 305, which causes the clamping force on the material between the clamping plates 303 to disappear, causing the material to slide during the movement, the traction force of the first elastic member 304 on the traction rope 305 is twice the traction force of the torsion spring 307 on the traction rope 305. The traction force of the slide post 302 on the traction rope 305 is designed so that the traction force of the slide post 302 on the traction rope 305 is greater than the traction force of the collecting stick 306, thereby ensuring that the clamping plate 303 does not loosen during the process of clamping the material, thereby improving the safety of the material during movement.

[0027] Considering that when placing materials, in order to improve the placement efficiency of materials, the rotating assembly 400 includes a cylinder 401 arranged at the end of the moving platform 101, and the piston rod at the end of the cylinder 401 drives the loading platform 200 to rotate on the surface of the moving platform 101. A driving gear 404 is arranged at the rotating shaft of the loading platform 200, and the driving gear 404 is meshed and rotated with the driven gear 308. The loading platform 200 is driven to rotate on the surface of the moving platform 101 by the piston rod at the end of the cylinder 401. The piston rod is rotatably connected to the bottom of the loading platform 200 through a connecting block. During the rotation of the loading platform 200, the materials placed on the surface of the loading platform 200 are subjected to the action of gravity and slide on the surface of the roller 201 , so that the material slides to the corresponding storage position. When the loading platform 200 is rotated, the driving gear 404 provided at the rotating shaft of the loading platform 200 rotates, and the driving gear 404 drives the driven gear 308 to engage and rotate during rotation, thereby winding the traction rope 305 wrapped around the surface of the collecting rod 306. The collecting rod 306 twists the torsion spring 307 during the rotation process, and at the same time, the pulling force of the traction rope 305 pulls the sliding column 302, so that the sliding column 302 squeezes the first elastic member 304, so that the external force on the material limited and fixed between the clamping plates 303 disappears, so that the material can quickly slide to the storage position, thereby improving the placement efficiency of the material.

[0028] Taking into account the different weights of different materials, when the worktable 200 is horizontally adjusted by the cylinder 401, the service life of the cylinder 401 is easily reduced. Therefore, sliding bars 402 are provided at the four corners between the moving platform 101 and the worktable 200, and a second elastic member 403 is provided inside the sliding bar 402. The worktable 200 is supported by the sliding bar 402 to reduce the load-bearing of the piston rod at the end of the cylinder 401 on the worktable 200. By arranging sliding bars 402 at the four corners of the moving platform 101 and the worktable 200, and arranging a second elastic member 403 inside the sliding bar 402, the sliding bar 402 is supported by the second elastic member 403, so that the sliding bar 402 provides supporting force for the worktable 200, thereby preventing the cylinder 401 from being always in a stressed state, thereby improving the service life of the cylinder 401.

[0029] Considering that in the process of picking up materials, in order to facilitate the rapid picking up of materials, the unloading assembly 500 includes a groove arranged on the surface of the loading platform 200, a support rod 501 is arranged at the groove, a shovel plate 502 is rotatably arranged on the surface of the support rod 501, a third elastic member 503 is arranged on the surface of the support rod 501, and the shovel plate 502 and the groove side wall are connected to the two sides of the third elastic member 503 respectively. In the natural state, the shovel plate 502 is subjected to the force of the third elastic member 503 and forms an angle of 45° with the horizontal plane. A cut corner 504 is arranged at the bottom of the shovel plate 502. When there is no external force, the cut corner 504 passes through the movable platform 1 parallel to the horizontal plane. 01 to the end face of the storage position, rotate the loading platform 200 on the surface of the moving platform 101, so that the cut corner 504 provided at the bottom of the shovel plate 502 slides on the surface of the storage position, and during the movement of the shovel plate 502, the bottom of the shovel plate 502 and the surface of the storage position form a triangular stable structure, so that the material continues to move along the surface of the shovel plate 502, and the end of the material is limited by the rotating roller 203, so that the material quickly falls on the surface of the loading platform 200, and the loading platform 200 is rotated to a horizontal position, so that the material falling on the surface of the loading platform 200 is clamped and fixed by the force of the limiting component 300, thereby facilitating the rapid removal of the material and improving safety.

[0030] The second object of the present invention is to provide a method for using a stacker for a stainless steel production stereoscopic warehouse, including any one of the above-mentioned stackers for stainless steel production stereoscopic warehouses, comprising the following steps: S1. Place the material on the surface of the loading platform 200, automatically limit and fix both sides of the material through the limit assembly 300, and slide the moving platform 101 on the surface of the traction frame 100 to drive the material to move vertically to the corresponding storage position height; S2, start the motor 102 to drive the gear body 103 to rotate, drive the rack meshing with the surface of the gear body 103 to move horizontally, so that the loading platform 200 moves to the inside of the storage position, and drive the loading platform 200 to rotate on the surface of the moving platform 101 through the rotating component 400. During the rotation of the loading platform 200, the limiting component 300 releases the limiting fixation of the material, so that the material slides from the surface of the roller 201 to the corresponding storage position; S3. When the material limited at the limiting component 300 slides down, a limiting beam 202 is set on the surface of the loading platform 200 near the storage position, and the height of the lifted material is limited by the limiting beam 202. At the same time, a rotating roller 203 is set at the bottom of the limiting beam 202. The rolling friction between the rotating roller 203 and the material can reduce the friction between the material and the limiting beam 202, thereby avoiding the lifting of the end of the material and blocking it outside the storage position.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.

The stacker for stainless steel production high-bay warehouse according to claim 1, characterized in that: The unloading assembly (500) comprises a groove arranged on the surface of the loading platform (200), a support rod (501) is arranged at the groove, a shovel plate (502) is rotatably arranged on the surface of the support rod (501), a third elastic member (503) is arranged on the surface of the support rod (501), and the shovel plate (502) and the groove side wall are respectively connected on both sides of the third elastic member (503), and in a natural state, the shovel plate (502) is subjected to the force of the third elastic member (503) and forms an angle of 45° with the horizontal plane, and a cut angle (504) is arranged at the bottom of the shovel plate (502), and the cut angle (504) is parallel to the horizontal plane when there is no external force.

9. A method for using a stacker for a stainless steel production high-bay warehouse, comprising the stacker for a stainless steel production high-bay warehouse according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1, placing the material on the surface of the loading platform (200), automatically limiting and fixing both sides of the material through the limiting assembly (300), and sliding the moving platform (101) on the surface of the traction frame (100) to drive the material to move vertically to the corresponding storage position height; S2, starting the motor (102) to drive the gear body (103) to rotate, driving the rack meshing with the surface of the gear body (103) to move horizontally, so that the loading platform (200) moves to the inside of the storage position, and driving the loading platform (200) to rotate on the surface of the moving platform (101) through the rotating component (400). During the rotation of the loading platform (200), the limiting component (300) is released to fix the material, so that the material slides from the surface of the roller (201) to the corresponding storage position; S3. When the material limited at the limiting assembly (300) slides down, a limiting beam (202) is provided on the surface of the loading platform (200) near the storage position, and the height of the lifted material is limited by the limiting beam (202). At the same time, a rotating roller (203) is provided at the bottom of the limiting beam (202). The rolling friction between the rotating roller (203) and the material reduces the friction between the material and the limiting beam (202), thereby preventing the lifted end of the material from being blocked outside the storage position.
