Description
Technical Field
[0001] This utility model relates to a demolding and transfer device for concrete bricks, belonging to the technical field of building material production equipment. Background Technology
[0002] Concrete bricks (cement bricks) are made by mixing sand, cement, and other materials, then pouring or pressing them into shape. The brick-making process includes batching, pouring or pressing, curing, demolding, and storage. The pouring or pressing process involves pressing or pouring the brick blank onto a mold on a pallet. After curing, the pallet must be demolded from the concrete brick. Patent application CN209972856U discloses a fully automated concrete brick stacking and packaging production line. Its left and right conventional layer concrete brick conveyor lines are used to transport the concrete bricks needed for stacking the conventional layers. Conventional layer gripping robots and perforated layer gripping robots are located on opposite sides of the stacking conveyor lines. The conventional layer gripping robots alternately grip the concrete bricks transported from the left and right conventional layer conveyor lines, stacking the concrete bricks layer by layer on the stacking conveyor lines in a crisscross pattern. Each concrete brick stack includes a perforated layer. The perforated layer concrete brick conveyor line is used to transport the concrete bricks needed for stacking the perforated layer. The perforated layer gripping robots grip the concrete bricks on the perforated layer concrete brick conveyor line. This application features a high degree of automation in the entire production line. The concrete brick packaging has perforations, eliminating the need for a bottom pallet and facilitating forklift operation.
[0003] This method relies on a robotic arm for grasping and transferring concrete bricks. The robotic arm needs precise positioning during use; even slight deviations can lead to unsuccessful grasping and transfer failure. Furthermore, because the robotic arm needs to clamp and apply pressure to the concrete brick during grasping, if the brick shifts and the clamping position is at the apex of the brick, the small force-bearing area can easily damage it. Additionally, it needs to overcome the centrifugal force on the concrete brick during transfer; the faster the transfer, the greater the centrifugal force, requiring a larger clamping force, and thus increasing the likelihood of damage. Therefore, it is necessary to design a concrete brick demolding and transfer device to solve these problems. Summary of the Invention
[0004] The purpose of this utility model is to provide a concrete brick demolding and transfer device that can easily separate the pallet from the concrete brick and reduce damage to the concrete brick during the transfer process, thereby reducing losses.
[0005] The purpose of this utility model is:
[0006] A demolding and transfer device for concrete bricks comprises a truss, a conveyor frame, a front translational pusher frame, a rear translational pusher frame, a translational plate frame, and a transition plate. The device is characterized in that: a conveyor frame is provided at one end of the truss, and a front translational pusher frame is provided on the truss above the conveyor frame; a rear translational pusher frame is provided at the other end of the truss, and a translational plate frame is provided on the truss below the rear translational pusher frame; a transition plate is fixedly installed on the truss between the translational plate frame and the conveyor frame.

[0010] The pushing mechanism consists of a limit plate, a lifting plate frame, a lifting cylinder, and a push plate arranged in parallel. The lifting plate frame is movably installed between the limit plates through multiple sets of grooved wheels. A lifting cylinder is set in the middle between the limit plates, and the piston rod end of the lifting cylinder is hinged to the bottom of the lifting plate frame. A push plate is set at the bottom of the lifting plate frame. The limit plate is fixedly connected to the support plate. The cylinder body of the lifting cylinder is hinged to the support plate.
[0011] The aforementioned translation frame consists of a translation slide plate, a translation rack, a translation shaft, a translation motor, and translation gears.

[0012] A waste chute is provided on the truss below the translation plate frame on one side of the transition plate, and a guide and blocking mechanism is provided on the truss above the translation plate frame on one side of the transition plate.
[0013] The guiding and blocking mechanism consists of a bracket, a guiding and blocking plate, and a tilting cylinder. The bracket is in the shape of an inverted U. The guiding and blocking plate is movably installed between the bottom ends of the bracket via a pin. The tilting cylinder is movably installed at the center of the top of the bracket. The piston rod end of the tilting cylinder is hinged to the guiding and blocking plate. The bracket is fixedly connected to the truss.
[0014] The beneficial effects of this utility model are as follows:
[0015] This concrete brick demolding and transfer device uses a front translational pushing mechanism and a rear translational pushing frame to push the concrete brick. By pushing the concrete brick, it can be easily separated from the pallet, and the pushing can be completed as long as the concrete brick is on the pallet, which greatly reduces the positioning requirements of the concrete brick. At the same time, because the transfer is done by pushing, the force on the concrete brick is effectively reduced compared to clamping and transferring, avoiding damage to the concrete brick, reducing losses, and effectively reducing production costs. It solves the problems of existing robotic arms that require accurate positioning during gripping and transfer, are inconvenient to transfer, and are prone to damaging concrete bricks.

[0023] The concrete brick demolding and transfer device consists of a truss 1, a conveyor frame 2, a front translational pusher frame 3, a rear translational pusher frame 4, a translational plate frame 5, and a transition plate 6. The conveyor frame 2, which can be either a conveyor chain or a conveyor belt, is located at one end of the truss 1. The front translational pusher frame 3 is mounted on the truss 1 above the conveyor frame 2, and the rear translational pusher frame 4 is located at the other end of the truss 1. The translational plate frame 5 is mounted on the truss 1 below the rear translational pusher frame 4. The transition plate 6 is fixedly installed on the truss 1 between the translational plate frame 5 and the conveyor frame 2. The function of the front translational pusher frame 3 is to push the conveyor frame 2 to the concrete brick below the translational pusher frame 3, thereby demolding the concrete brick from the pallet and separating the pallet from the concrete brick before pushing it onto the translational plate frame 5. The function of the rear translational pusher 4 is to push the concrete brick from one end of the translational plate 5 to the other end of the translational plate 5, thereby enabling the translational plate 5 to convey the concrete brick to the next process. Since the front translational pusher 3 and the rear translational pusher 4 transfer the concrete brick by pushing, the positioning requirements for the concrete brick are greatly reduced. At the same time, because the transfer is by pushing, compared with clamping transfer, the force on the concrete brick is effectively reduced, avoiding damage to the concrete brick, reducing losses, and effectively reducing production costs.
[0024] The truss 1 and the conveyor frame 2 are arranged in a cross shape. A baffle 7 is installed on the truss 1 above the end of the conveyor frame 2. The bottom edge of the baffle 7 is spaced apart from the conveyor frame 2. The height between the bottom edge of the baffle 7 and the conveyor frame 2 is sufficient to allow the pallet to pass through and to block the concrete bricks. The baffle 7 blocks the concrete bricks from moving forward during the transport of the pallet, leaving them at the transfer position and ensuring the transfer of the concrete bricks. At the same time, the baffle 7 can scrape off the residue on the pallet during the transport of the pallet and clean the pallet.
[0025] The front translation pusher 3 and the rear translation pusher 4 are respectively composed of a translation mechanism and a pusher mechanism. The translation mechanism drives the pusher mechanism to move, and then the pusher mechanism pushes the concrete brick, thereby separating the concrete brick from the pallet and transferring the concrete brick.
[0026] The translation mechanism consists of a support plate 301, a drive rack 302, a drive shaft 303, a drive motor 304, and a drive gear 305. Drive racks 302 are respectively installed on the outer sides of both ends of the support plate 301. The drive shaft 303 is movably mounted on the support plate 301 via bearing seats. The drive motor 304 is located in the middle of the support plate 301 and is connected to the drive shaft 303 via a reducer. Drive gears 305 are respectively installed on both ends of the drive shaft 303, and the drive gears 305 mesh with the drive racks 302. The drive racks 302 are fixedly connected to the truss 1, and the support plate 301 is movably connected to the truss 1 via rollers 306. The function of the drive motor 304 is to drive the drive shaft 303 to rotate, which in turn drives the drive gears 305 to rotate. Thus, the interaction between the drive gears 305 and the drive racks 302 propels the support plate 301 to move.
[0027] The pushing mechanism consists of a limit plate 307, a lifting plate frame 308, a lifting cylinder 309, and a push plate 310 arranged in parallel. The lifting plate frame 308 is movably mounted between the limit plates 307 via multiple sets of grooved wheels 311. The lifting cylinder 309 is located in the middle between the limit plates 307, and the piston rod end of the lifting cylinder 309 is hinged to the bottom of the lifting plate frame 308. The push plate 310 is located at the bottom of the lifting plate frame 308. The limit plates 307 are fixedly connected to the support plate 301. The cylinder body of the lifting cylinder 309 is hinged to the support plate 301. The function of the grooved wheels 311 is to support the lifting plate frame 308, so that the support plate 301 can sequentially drive the lifting plate frame 308 to translate via the limit plates 307 and the grooved wheels 311, thereby driving the push plate 310 to translate, and thus pushing the concrete bricks through the moving push plate 310. The function of the lifting cylinder 309 is to drive the lifting plate frame 308 to rise and fall, which in turn drives the push plate 310 to rise and fall, so that the push plate 310 can be inserted between the concrete bricks to push and transfer one or more bricks individually, thereby separating qualified products from defective products.
[0028] The translation frame 5 consists of a translation slide plate 501, a translation rack 502, a translation shaft 503, a translation motor 504, and a translation gear 505. The translation rack 502 is arranged side by side at the bottom of the translation slide plate 501. The translation shaft 503 is arranged below the translation slide plate 501. The translation motor 504 is arranged at one end of the translation shaft 503 and is connected to the translation shaft 503 through a reducer. The translation gear 505 is arranged side by side on the translation shaft 503 and meshes with the translation rack 502. The translation slide plate 501 is movably connected to the truss 1 through rollers 306. The translation motor 504 is fixedly connected to the truss 1 through a reducer. The other end of the translation shaft 503 is movably connected to the truss 1 through a bearing seat. The function of the translation motor 504 is to drive the translation shaft 503 to rotate, which in turn drives the translation gears 505 at both ends of the translation shaft to rotate. Through the interaction between the translation gears 505 and the translation rack 502, the translation rack 502 is driven to move, thereby pushing the translation slide plate 501 to move, which in turn drives the concrete bricks on the translation slide plate 501 to move.
[0029] A waste chute 8 is provided on the truss 1 below the translational frame 5 on one side of the transition plate 6 to guide defective products and stack them on the outside of the sub-truss 1. A guide blocking mechanism 9 is provided on the truss 1 above the translational frame 5 on one side of the transition plate 6 to block and guide defective products, ensuring that defective products can enter the waste chute 8.
[0030] The guiding and blocking mechanism consists of a bracket 901, a guiding and blocking plate 902, and a tilting cylinder 903. The bracket 901 is inverted U-shaped. The guiding and blocking plate 902 is movably mounted between the bottom ends of the bracket 901 via a pin. The tilting cylinder 903 is movably mounted at the center of the top of the bracket 901. The piston rod end of the tilting cylinder 903 is hinged to the guiding and blocking plate 902. The bracket 901 is fixedly connected to the truss 1. The function of the tilting cylinder 903 is to drive the guiding and blocking plate 902 to rotate around the pin and tilt. After tilting, it can block defective products and prevent them from falling into the waste chute 8 under the obstruction of the guiding and blocking plate 902 during the movement of the concrete bricks driven by the sliding plate 501.
[0031] When the concrete brick demolding and transfer device is working, after the concrete brick pallet is transferred to the conveyor frame 2, the conveyor frame 2 is started, and the conveyor frame 2 moves the pallet and concrete brick to the baffle 7. After the pallet and concrete brick are in place, the lifting cylinder 309 of the front translation push frame 3 is started. The lifting cylinder 309 pushes the push plate 310 downward through the lifting plate frame 308, moving the push plate 310 to one side of the concrete brick. After the push plate 310 is in place, the drive motor 304 of the front translation push frame 3 is started. The drive motor 304 drives the push plate 310 to move through the reducer, drive shaft 303, drive gear 305, drive rack 302, support plate 301, limit plate 307, grooved wheel 311, and lifting plate frame 308 in sequence, thereby pushing the concrete brick to move, so that the concrete brick is separated from the pallet, and after separation, it moves to the translation slide plate 501 of the translation plate frame 5 through the transition plate 6. After the concrete brick is moved onto the translation slide plate 501, the translation plate frame 5 is activated, and the concrete brick is conveyed forward by the moving translation slide plate 501. After being conveyed to the correct position, the rear translation pusher 4 is activated, and the concrete brick is pushed from one end of the translation slide plate 501 to the other end of the translation slide plate 501 by the rear translation pusher 4, so that the concrete brick enters the next process.
[0032] After a defective product is found, the qualified concrete bricks on the pallet are transferred to the next process. The defective product is then pushed onto the translation slide plate 501 via the front translation pusher 3. Once the defective product is in place, the tilting cylinder 903 of the guide blocking frame 9 is activated, which drives the guide blocking plate 902 to tilt. After the guide blocking plate 902 tilts into place, the translation slide plate 501 moves the defective product, and under the guidance and obstruction of the guide blocking plate 902, the defective product falls into the waste chute 8. The defective product is then piled up on the outside of the truss 1 via the inclined waste chute 8.
[0033] The concrete brick demolding and transfer device uses a front translational pushing mechanism 3 and a rear translational pushing frame 4 to push the concrete brick. By pushing the concrete brick, it can be easily separated from the pallet, and the pushing can be completed as long as the concrete brick is on the pallet, which greatly reduces the positioning requirements of the concrete brick. At the same time, because the transfer is done by pushing, the force on the concrete brick is effectively reduced compared to clamping and transferring, avoiding damage to the concrete brick, reducing losses, and effectively reducing production costs. It solves the problems of existing robotic arms that require accurate positioning during gripping and transfer, are inconvenient to transfer, and are prone to damaging concrete bricks.
