Description

Technical Field

[0001] The present application relates to the technical field of aerated concrete block packaging, and in particular to a packaging device and a packaging method for aerated concrete blocks. Background Art

[0002] Aerated concrete blocks are a kind of building material made of cement, sand, water and foaming agent. It has the characteristics of light weight, heat preservation, heat insulation and sound insulation, and is suitable for building walls, partitions, sound insulation walls, etc. Aerated concrete blocks can reduce the use of labor and materials during the construction process and improve construction efficiency, so they have been widely used in construction projects. The existing block stack is a rectangular parallelepiped, and the stack type of a layer of blocks is two in the length direction and six in the width direction.

[0003] At present, most of the block packaging systems on the market need to transport and convey the blocks by pallets. The pallets used are heavy, large in quantity and difficult to recycle. The existing pallet transportation methods generally rely on manual labor, resulting in a series of problems such as low automation, low production efficiency, large production and labor cost investment, and certain safety hazards. Referring to the Chinese patent application document with the publication number CN114104385A, it discloses a pallet-free fully automatic packaging system for autoclaved aerated concrete blocks. The patent stacking robot clamps and delivers the finished blocks to the block conveyor line. The block conveyor clamps the small blocks on the block conveyor line and cooperates with the stacking robot to arrange and place the blocks on the stacking conveyor line, so as to form a forklift slot in the entire block stack for forklift transportation. If the number of small blocks on the block conveyor line is insufficient, the stacking robot will grab a layer of blocks and place them on the block conveyor line.

[0004] With regard to the above-mentioned related technologies, a block discharging robot clamps small blocks on a block discharging conveyor line and cooperates with a stacking robot to arrange and place the blocks so as to form a forklift slot. This process is rather cumbersome and is not conducive to improving work efficiency. In addition, the number of blocks on the block discharging conveyor line is insufficient and needs to be supplemented, which is still not conducive to improving work efficiency. Summary of the invention

[0005] In view of this, the present application provides a packaging device and a packaging method for aerated concrete blocks, aiming to solve the problem in the prior art that the process of forming a forklift slot from a block stack is relatively cumbersome.

[0006] To solve the above technical problems, in the first aspect, the present application provides a packaging device for aerated concrete blocks, comprising a frame and a conveyor belt passing through the frame, and a packaging device for aerated concrete blocks, further comprising: a support plate fixedly connected to the top of the frame, the conveying direction of the conveyor belt and the direction of the length of the blocks being perpendicular to each other, the support plate being connected with a clamping mechanism for moving the upper blocks upward, a rotating mechanism for rotating a layer of blocks adjacent to the bottom layer being arranged under the support plate, the rotating mechanism being connected with an adjusting mechanism for arranging the rotated layer of blocks and forming a forklift slot for facilitating the insertion of a forklift, and the adjusting mechanism also comprising a limiting member for aligning the rotated blocks with the new stacking type.

[0007] By adopting the above technical solution, when the block stacks need to be packaged, the conveyor belt first conveys the stacked blocks to the bottom of the support plate, and then the blocks on the upper layer of the stack are moved upwards by the clamping mechanism, and then the layer of blocks adjacent to the bottom layer is rotated by the rotating mechanism, and then the rotated layer of blocks is moved by the adjusting mechanism and the moved blocks are aligned with the original stack shape by the limiter, thereby forming a forklift slot that is convenient for forklifts to insert, so that the subsequently packaged blocks can be transported by forklifts. Compared with the prior art of lifting the upper layer of blocks and then stacking the blocks on top of the bottom layer of blocks, the time for forming the forklift slot is reduced, which is conducive to improving work efficiency.

[0008] Optionally, a first rotation source is fixedly installed on the top of the support plate, and the output shaft of the first rotation source is fixedly connected to a first gear, and the first gear is meshed with a rack that is slidably connected to the frame and vertically arranged; a first connecting frame is fixedly connected to the bottom of the rack, and the first connecting frame is fixedly installed with a first linear drive and a second linear drive, the output shaft of the first linear drive is fixedly connected to a first clamping plate, and the output shaft of the second linear drive is fixedly connected to a second clamping plate, and the first clamping plate and the second clamping plate can clamp the upper stacking blocks.

[0009] By adopting the above technical solution, when it is necessary to clamp the upper layer of building blocks, first, when the completed building block stack moves to the bottom of the support plate, the first linear drive and the second linear drive are started to drive the first clamping plate and the second clamping plate to approach each other and clamp the upper layer of building blocks, and then the first rotation source is started to drive the first gear to rotate, and then the rack is driven to move upward, thereby driving the upper layer of building blocks to move upward, so as to facilitate subsequent work.

[0010] The transmission gear of the present invention is a gear selected from the group consisting of a first gear and a second gear coupled to the gear of the present invention, a second gear coupled to the gear of the present invention being coupled to a gear coupled to the gear of the present invention.

[0011] By adopting the above technical solution, when it is necessary to rotate a layer of building blocks adjacent to the bottom layer of the stack, the third linear drive is started to drive the pressure plate to press against the second-to-last layer of building blocks, and the pressure plates on both sides press against the two sides of a layer of building blocks, and then the third rotation source is started to drive the screw to rotate, and the rotation of the screw drives the movable frame to move upward to lift the second-to-last layer of building blocks, and then the second rotation source is started to drive the third gear to rotate, and then the third gear rotates around the second gear and drives the rotating frame to rotate, so that the second-to-last layer of building blocks is rotated ninety degrees to facilitate subsequent work.

[0012] Optionally, the second connecting frame, the third linear drive, the third connecting frame, and the pressure plate on each side are respectively provided in three, and each of the pressure plates can respectively abut two building blocks, the adjusting mechanism includes a fourth linear drive arranged on both sides of the movable frame, and each of the fourth linear drives in the movable frame is respectively provided with two, the output shaft of each of the fourth linear drives is respectively fixedly connected to a moving block fixedly connected to the second connecting frame, and each of the third connecting frames is respectively fixedly installed with a fourth rotation source, the fourth rotation source is used to drive the pressure plate to rotate, and the adjusting mechanism also includes a limiter for limiting the positions of the building blocks on both sides.

[0013] By adopting the above technical solution, when it is necessary to form a forklift slot, the fourth linear drive is started to drive the moving block to move and drive the second connecting frames on both sides of the moving frame to move away from each other, thereby separating the second-to-last layer of building blocks into three groups, and then the fourth rotation source is started to drive the pressure plate to rotate, and then the three groups of building blocks are rotated, and then the two second connecting frames are driven closer to each other through the fourth linear drive, so that the rotated building blocks return to the top of the bottom layer of building blocks, thereby forming a forklift slot, which is conducive to improving work efficiency.

[0014] Optionally, the limiting member includes a connecting plate fixedly connected to the bottom of both sides of each rotating frame, each connecting plate is fixedly connected to a pull rope at the bottom, each moving frame is fixedly connected to a connecting shell at the bottom on both sides, the pull rope passes through the connecting shell and the bottom of the pull rope is fixedly connected to a limiting block, the bottom of the limiting block abuts against the top of the moving block, and a spring is fixedly connected between the limiting block and the inner top wall of the connecting shell.

[0015] By adopting the above technical solution, when it is necessary to make a layer of blocks adjacent to the bottom layer correspond to the blocks of the bottom layer, since the blocks are rectangular blocks, when the blocks are rotated and the two groups of blocks on the outside are brought close to each other, since the width of the blocks will change, it is necessary to limit the length of movement of the blocks so as to correspond to the blocks of the bottom layer. First, the fourth linear drive is started to drive the moving block to move and make the second connecting frames on both sides of the moving frame close to each other. During the rising process of the moving frame, the moving block moves upward and pushes the limit block to move upward. Then, when the moving block drives the second connecting frame away from each other, the limit block moves downward under the action of the spring and abuts the output shaft of the fourth linear drive. Then, when the moving block drives the two groups of blocks on the outside to approach each other, the moving block abuts the limit block to stop the block from moving. At this time, the two groups of blocks on both sides correspond to the blocks of the bottom layer. When the size of the blocks changes, the correspondence with the blocks of the bottom layer can be achieved by changing the size of the limit block, and a forklift groove is formed between the three groups of blocks. Through this device, there is no need to add an additional power source or add a step of removing the blocks, which is conducive to improving work efficiency.

[0016] Optionally, the first clamping plate, the second clamping plate and the pressing plate are made of flexible material at their contact points with the building blocks.

[0017] By adopting the above technical solution, the provision of the flexible material can protect the surface of the building block, so as to improve the quality of the building block.

[0018] In a second aspect, the present application provides a method for packaging aerated concrete blocks, including a packaging device for aerated concrete blocks in the first aspect, wherein the method comprises:

[0019] S1, lift the upper block;

[0020] S2, rotate a layer of blocks adjacent to the bottom layer of blocks;

[0021] S3, separating a layer of blocks adjacent to the bottom layer of blocks, starting the fourth linear actuator to drive the moving block to move and drive the second connecting frames on both sides of the moving frame to move away from each other, thereby separating the penultimate layer of blocks into three groups;

[0022] S4, rotating the three groups of building blocks, the pressing plate rotates to rotate the three groups of building blocks;

[0023] S5, corresponding to the three groups of building blocks, the moving block moves and brings the second connecting frames closer to each other, the moving block moves upward and pushes the limiting block to move upward, the moving block drives the second connecting frames away from each other, then the moving block drives the two outer groups of building blocks closer to each other, and the moving block abuts against the limiting block to stop the building blocks from moving;

[0024] S6, converting into a whole stack, making the three groups of blocks descend and abut against the bottom blocks, and making the upper blocks move down and abut against the three groups of blocks, forming a new stack type with forklift slots.

[0025] By adopting the above technical solution, the original stack is reorganized so that the new stack has forklift holes that are convenient for forklift transportation, reducing the process of removing blocks from the original stack, which is conducive to improving work efficiency.

[0026] Optionally, in step S2, the pressure plates on both sides can press against both sides of a layer of building blocks, and the third gear rotates around the second gear and drives the rotating frame to rotate so that the second to last layer of building blocks rotates ninety degrees.

[0027] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0028] 1. This device can move blocks on the original stack to form a forklift slot for forklift transportation, without adding an additional power source or adding a process of removing blocks to form a limit slot, which is conducive to improving work efficiency.

[0030] 3. When stacking building blocks of different specifications, the size of the limit blocks can be set to neatly stack the building blocks of the new type, so as to improve practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] When it is necessary to rotate a layer of blocks adjacent to the bottom layer of the stacking, the third linear actuator 46 is started to drive the pressure plate 48 to press against the second-to-last layer of blocks, and the pressure plates 48 on both sides press against both sides of a layer of blocks, and then the third rotation source 442 is started to drive the screw 443 to rotate, and the rotation of the screw 443 drives the movable frame 441 to move upward to lift the second-to-last layer of blocks, and then the second rotation source 431 is started to drive the third gear 432 to rotate, and then the third gear 432 rotates around the second gear 42 and drives the rotating frame 44 to rotate, so that the second-to-last layer of blocks is rotated ninety degrees to facilitate subsequent work.

[0044] Reference Figure 1 and Figure 5 The adjusting mechanism 5 includes fourth linear actuators 51 arranged on both sides of the moving interior, and each moving frame 441 is provided with two fourth linear actuators 51 respectively. The output shaft of each fourth linear actuator 51 is respectively fixedly connected with a moving block 52 fixedly connected with the second connecting frames 45 on both sides.

The adjusting mechanism 5 also includes a limiter 6 for limiting the position of the building blocks on both sides.

[0045] When it is necessary to form a forklift slot, the fourth linear actuator 51 is started to drive the moving block 52 to move and drive the second connecting frames 45 on both sides of the moving frame 441 to move away from each other, thereby separating the second-to-last layer of building blocks into three groups, and then the fourth rotation source 53 is started to drive the pressure plate 48 to rotate, and then the three groups of building blocks are rotated, and then the two second connecting frames 45 are driven to approach each other through the fourth linear actuator 51, so that the rotated building blocks return to the top of the bottom layer of building blocks, thereby forming a forklift slot, which is beneficial to improving work efficiency.

[0046] Reference Figure 1 , Figure 2 and Figure 5 The limiting member 6 includes a connecting plate 61 fixedly connected to the bottom of both sides of each rotating frame 44, a pull rope 62 is fixedly connected to the bottom of each connecting plate 61, a connecting shell 63 is fixedly connected to the bottom of both sides of each rotating frame 44, the pull rope 62 passes through the connecting shell 63 and the bottom of the pull rope 62 is fixedly connected to the limiting block 64, the limiting block 64 can slide in the connecting shell 63, and the bottom of the limiting block 64 abuts against the top of the moving block 52, and a spring 65 is fixedly connected between the limiting block 64 and the inner top wall of the connecting shell 63.

[0047] When it is necessary to make the building blocks of a layer adjacent to the bottom layer correspond to the building blocks of the bottom layer, since the building blocks are rectangular building blocks, when the building blocks are rotated and the two groups of building blocks on the outside are brought closer to each other, the width of the building blocks will change, so it is necessary to limit the length of movement of the building blocks so as to correspond to the building blocks of the bottom layer. First, the fourth linear actuator 51 is started to drive the moving block 52 to move and make the second connecting frames 45 on both sides of the moving frame 441 approach each other. During the rising process of the moving frame 441, the moving block 52 moves upward and pushes the limiting block 64 to move upward. Then, the moving block 52 drives the second connecting frames 45 to move together. When moving away, the limit block 64 moves downward under the action of the spring 65 and abuts the output shaft of the fourth linear drive 51. Then, when the moving block 52 drives the two groups of building blocks on the outside to approach each other, the moving block 52 abuts the limit block 64 to stop the movement of the building blocks. At this time, the two groups of building blocks on both sides correspond to the building blocks on the bottom layer. When the size of the building blocks changes, the size of the limit block 64 can be changed to correspond to the building blocks on the bottom layer, and a forklift groove is formed between the three groups of building blocks. Through this device, there is no need to add an additional power source or increase the steps of removing the building blocks, which is conducive to improving work efficiency.

[0048] The implementation principle of the packaging device of aerated concrete blocks in the embodiment of the present application is as follows: first, when the completed block stack moves to the bottom of the support plate 11 through the conveyor belt 2, the block stack stops moving, and then the first linear drive 35 and the second linear drive 36 are started to drive the first clamping plate 37 and the second clamping plate 38 to approach each other and clamp the three layers of blocks on the top, and then the first rotation source 31 is started to drive the first gear 32 to rotate, and then the rack 33 is driven to move upward to drive the three layers of blocks to move upward, and then the third linear drive 46 is started to drive the pressure plates 48 on both sides to respectively press against the two blocks, and then the third rotation source 442 is started to drive the screw 443 to rotate, and the rotation of the screw 443 drives the moving frame 441 to move upward so that the second to last layer of blocks moves upward, and then the second rotation source 431 is started to drive the third gear 432 to rotate, and then the third gear 432 rotates around the second gear 42 and drives the rotating frame 44 to rotate, and the second to last layer of blocks rotates ninety degrees.

[0049] Then, the fourth linear actuator 51 is started to drive the moving block 52 to move and the second connecting frames 45 on both sides of the moving frame 441 to move away from each other, and the penultimate layer of building blocks is separated into three groups, each group having two building blocks. Then, the fourth rotation source 53 is started to drive the pressure plate 48 to rotate, and then the three groups of building blocks are rotated.

[0050] During the rising process of the moving frame 441, the moving block 52 moves upward and pushes the limit block 64 to move upward, and compresses the spring 65. Then, when the moving block 52 drives the second connecting frame 45 to move away from each other, the limit block 64 moves downward under the action of the spring 65 and abuts against the output shaft of the fourth linear drive 51. Then, when the moving block 52 drives the two groups of building blocks on the outside to approach each other, the moving block 52 abuts against the limit block 64 to stop the movement of the building blocks. At this time, the two groups of building blocks on both sides correspond to the building blocks on the bottom layer, and a forklift groove is formed between the three groups of building blocks.

[0051] Start the third rotation source 442 to drive the screw 443 to rotate and move the moving frame 441 downward, and drive the three groups of building blocks to move downward and abut against the top of the bottom layer of building blocks. When the moving frame 441 moves downward so that the limit block 64 is located above the moving block 52, the moving block 52 can return to its original position to facilitate the next work. Then start the first rotation source 31 to drive the rack 33 to move downward so that the top three layers of building blocks abut against the three groups of building blocks, and finally form a new stacking type with a forklift slot.

Then, when the moving block 52 drives the second connecting frames 45 to move away from each other, the limit block 64 moves downward under the action of the spring 65 and abuts against the output shaft of the fourth linear actuator 51. Then, when the moving block 52 drives the two outer groups of building blocks to approach each other, the moving block 52 abuts against the limit block 64 to stop the building blocks from moving.
