Description

Technical Field

[0001] This invention relates to the field of stacking aerated concrete billets, and more particularly to a stacking device for aerated concrete billets. Background Technology

[0002] Autoclaved aerated concrete (AAC) is a lightweight, porous silicate product made primarily from siliceous and calcareous materials, with the addition of a foaming agent, through processes such as batching, mixing, pouring, pre-curing, cutting, autoclaving, and curing. AAC blocks are lightweight, porous, and possess good thermal insulation, fire resistance, nailability, sawing, and planing capabilities. They also exhibit some seismic resistance and good environmental performance, making them an excellent new type of building material.

[0003] When preparing aerated concrete blocks, the raw materials are first metered and batched and then put into a pouring mixer. After being mixed evenly, the mixture is poured into a mold. After pre-curing at a certain temperature and time and the green body reaches a certain hardness, the green body is lifted by a tilting hoist to a cutting machine for cutting. The cut green bodies are then lifted by a semi-finished product hoist to a steam curing trolley, and then grouped into a steam curing kettle for high-temperature steam curing. After steam curing is completed, the green bodies are removed from the steam curing kettle and stacked by a stacking device.

[0004] In related technologies, a stacking equipment for aerated concrete block blanks includes a frame and a roller conveyor. Two symmetrical first guide rails are mounted on the upper side of the frame, and a first movable seat is slidably connected to each first guide rail. Two first pulleys are mounted on the side of the frame, and a first belt connects the first pulleys. The first movable seat is connected to one side of the first belt. A second guide rail is mounted on the first movable seat, and a second movable seat is slidably connected to the second guide rail. A third servo motor is mounted on the second movable seat, and a gear is mounted on the output shaft of the third servo motor. A lifting column is slidably connected to the third guide rail, and a vertical rack is mounted on the lifting column, with the gear meshing with the rack. A double-headed cylinder is mounted at the lower end of the lifting column, and a gripper is mounted on the push rod of the double-headed cylinder.

[0005] Regarding the aforementioned technologies, the inventors believe that during the stacking of block blanks, the blanks are stacked layer by layer, and the blanks at the bottom will be subjected to the pressure of the blanks above. The higher the number of stacked layers, the greater the pressure on the blanks at the bottom, which will cause damage to the blanks at the bottom. Moreover, it is difficult for the grippers to control the force when handling the blanks, which will also cause damage to the blanks when the grippers handle the blanks. Therefore, reducing the possibility of damage to the blanks during stacking is a problem that we urgently need to solve. Summary of the Invention

[0006] In order to reduce the possibility of damage to the billet during stacking, this application provides a stacking device for aerated concrete billets.

[0007] The palletizing equipment for aerated concrete billets provided in this application adopts the following technical solution:

[0008] A stacking device for aerated concrete billets, including a fixing frame;

[0009] A support mechanism, used in conjunction with the billet, comprising:

[0010] A support frame, one support frame for each blank, the support frame includes a base plate and a crossbeam, the crossbeam is connected to both sides of the base plate in the width direction, and the blank is placed on the base plate;

[0011] The support rod has two ends that are respectively inserted into two adjacent crossbeams. Each crossbeam is provided with a support tube that is inserted into the support rod. The distance between two adjacent bottom plates is greater than the thickness of the blank.

[0012] A transport mechanism, mounted on a fixed frame, includes:

[0013] The mounting frame is movably mounted on the fixed frame;

[0014] A transport assembly is disposed on the mounting frame. The transport assembly is disposed on both sides of the mounting frame in the width direction. Each set of the transport assembly includes two transport rods. A contact plate is disposed on the transport rod. The top surface of the contact plate contacts the bottom surface of the crossbeam.

[0015] A rotating assembly for driving the conveying rod to rotate;

[0016] A lifting assembly is used to drive the mounting frame to move vertically.

[0017] By adopting the above technical solution, each billet is first placed on its corresponding support frame, and the support rod is inserted into its corresponding support tube. When stacking the billets, the driving transport assembly is moved to the billet to be transported, and then the transport assembly is driven to descend so that the contact plate is below the crossbeam. Then the transport rod is driven to rotate until the top surface of the contact plate contacts the bottom surface of the crossbeam. After stable contact, the transport assembly is driven to rise and move above the stacking position, and then the transport assembly is driven to descend so that the lower end of the support tube on the crossbeam and the top end of the corresponding support rod are inserted. After insertion, the distance between two adjacent bottom plates is... The thickness of the blocks is greater than that of the billet itself, thus preventing squeezing between adjacent blocks during stacking. Pressure is transferred to the support frame via support rods and tubes, avoiding damage to the lower billet. The connection between the support rods and tubes also improves the stability of the stacking process. Furthermore, the transport rods move the billets via the moving beams, eliminating the need to control the handling force and preventing damage to the billets during transport. In summary, this greatly reduces the possibility of damage to the billets during stacking, providing multifaceted protection for the block billets.

[0018] Furthermore, the rotating assembly includes a first connecting sleeve, a second connecting sleeve, and a connecting rod. The first and second connecting sleeves are coaxially connected to two transport rods in the same set of transport assemblies. The transport rods are rotatably connected to the mounting frame. A first connecting plate and a second connecting plate are connected to the peripheral sidewall of the first connecting sleeve. The first and second connecting plates are located on opposite sides of the radial direction of the first connecting sleeve. The first connecting plate and its corresponding contact plate are located on the same side of the radial direction of the transport rod. A third connecting plate is connected to the peripheral sidewall of the second connecting sleeve. The third connecting plate and its corresponding contact plate are located on the same side of the radial direction of the transport rod. A transmission component for driving the first connecting plate to rotate is connected to the end of the first connecting plate away from the first connecting sleeve. One end of the connecting rod is rotatably connected to the second connecting plate, and the other end of the connecting rod is rotatably connected to the third connecting plate. The first and third connecting plates rotate in opposite directions.

[0019] By adopting the above technical solution, when the straight line of the length direction of the two contact plates in the same group is parallel to the straight line of the length direction of the crossbeam, the first connecting plate is located between the second connecting plate and the third connecting plate, and the third connecting plate is closer to the transmission component than the second connecting plate. When the contact plate needs to rotate until the top surface of the contact plate contacts the bottom surface of the crossbeam, the first connecting plate is driven to rotate away from the third connecting plate, the second connecting plate is driven to rotate towards the third connecting plate, and the third connecting plate is driven to rotate away from the first connecting plate. This causes the two contact plates to rotate away from each other until they can contact the bottom surface of the crossbeam. When it is necessary to make the straight line of the length direction of the two contact plates in the same group parallel to the straight line of the length direction of the crossbeam again, the first connecting plate is driven to rotate towards the third connecting plate, the second connecting plate is driven to rotate away from the third connecting plate, and the third connecting plate is driven to rotate towards the first connecting plate. This causes the two contact plates to rotate towards each other.

[0020] Furthermore, multiple sets of handling components are provided on each side of the support frame in the width direction, and each set of handling components corresponds to a set of rotating components. The transmission component is a transmission rod, which is arranged along the length direction of the support frame. One transmission rod is provided on each side of the support frame in the width direction. One transmission rod is simultaneously rotatably connected to the first connecting plate of the multiple sets of rotating components on one side of the support frame in the width direction. A telescopic hydraulic cylinder is provided on the mounting frame. The output end of the telescopic hydraulic cylinder is coaxially connected to the transmission rod, and the telescopic hydraulic cylinder drives the transmission rod to slide along its own axial direction.

[0021] By adopting the above technical solution, the setting of multiple sets of handling components improves the stability of the billet being handled and moved. The telescopic cylinder drives the transmission rod to slide along its own axis, driving multiple sets of handling components on each side of the support frame to move synchronously, improving the synchronicity of the rotation of multiple sets of handling rods on the mounting frame. Furthermore, with a simple structure for the cooperation between the rotating component and the transmission rod, multiple sets of handling components can be driven by only one telescopic cylinder, which is energy-saving and environmentally friendly.

[0022] Furthermore, the crossbeam is provided with a storage assembly for storing the support rod. One support rod corresponds to a set of storage assemblies. The storage assembly includes a storage plate. The storage plate at each support rod is located at both ends of the support rod in the length direction. The support rod is placed horizontally on the storage plate.

[0023] The fixed frame is equipped with a pneumatic gripper for removing the support rod from the storage plate and inserting it into the support tube, and an active mechanism for driving the pneumatic gripper to move. The active mechanism includes a first sliding component, a second sliding component, a third sliding component, and a rotating component. The first sliding component drives the pneumatic gripper to move in a direction parallel to the length of the billet, the second sliding component drives the pneumatic gripper to move in a vertical direction, the third sliding component drives the pneumatic gripper to move in a direction parallel to the width of the billet, and the rotating component drives the pneumatic gripper to rotate.

[0024] By adopting the above technical solution, before stacking the next blank, the pneumatic gripper is driven to move to the storage component to pick up the horizontally placed support rod. Then, the support rod is moved upward first, and then moved away from the crossbeam. The gripper is then driven to rotate to make the support rod vertical. The support rod is then moved into the support tube. The storage component reduces the possibility of the support rod being lost due to other placement. Furthermore, the pneumatic gripper, driven by the moving mechanism, can control the accuracy of each support rod being aligned with the support tube, improving the consistency of the height of the support rods on the same support frame after being inserted into the support tube.

[0025] Furthermore, both ends of the support rod are provided with guide surfaces, which are conical. When the support rod and the support tube are inserted, the guide surface of the support rod is located inside the support tube corresponding to the support rod.

[0026] By adopting the above technical solution, the setting of the guide surface provides guidance and limitation for the insertion of the support rod into the support tube, and also improves the smoothness of the insertion of the support rod into the support tube.

[0027] Furthermore, the two ends of the support rod are coaxially connected to a first positioning ring plate and a second positioning ring plate, respectively. The top of the support tube passes through the corresponding crossbeam and is coaxially connected to an auxiliary positioning ring plate. The bottom surface of the support tube is connected to the inner wall of the crossbeam. When the support rod and the support tube are inserted, the first positioning ring plate is located below the second positioning ring plate. The first positioning ring plate and the auxiliary positioning ring plate located below the first positioning ring plate abut against each other. The top surface of the second positioning ring plate abuts against the bottom surface of the crossbeam located above the second positioning ring plate.

[0028] By adopting the above technical solution, when the support rod and the support tube are inserted, the first positioning ring plate and the auxiliary positioning ring plate abut against each other, and the second positioning ring plate abuts against the bottom surface of the crossbeam, thereby positioning the depth of the support rod inserted into the support tube and improving the accuracy and stability of the insertion of the support rod and the support tube.

[0029] Furthermore, the distance between the first positioning ring plate and the adjacent guide surface is greater than the distance between the second positioning ring plate and the adjacent guide surface.

[0030] By adopting the above technical solution, since the lower end of the support rod is longer when it is under pressure, it is more stable. Therefore, the distance between the first positioning ring plate and the adjacent guide surface is set to be longer, so that it is not easy to shake when heavy objects are stacked on top of the support rod. The upper end of the support rod is for aligning the support tube of the support frame to be placed above it. Therefore, the distance between the second positioning ring plate and the adjacent guide surface is set to be shorter, so as to simultaneously meet the requirements of stable support and easy alignment.

[0031] Furthermore, the lifting assembly includes lifting cylinders, which are located at both ends of the fixed frame along its length. The output end of the lifting cylinder is connected to the mounting frame, and the lifting cylinder operates synchronously to drive the mounting frame to lift.

[0032] By adopting the above technical solution, the lifting cylinders at both ends of the fixed frame operate synchronously to drive the mounting frame to rise and fall stably.

[0033] Furthermore, the fixing frame is provided with a synchronization component, and fixing rods are vertically fixed at both ends of the fixing frame in the length direction. One fixing rod corresponds to one set of synchronization components, and two sets of synchronization components are symmetrically arranged. A horizontal rod is slidably connected between the two fixing rods.

[0034] The synchronization assembly includes a synchronization shaft, a synchronization gear, and a synchronization rack. Two synchronization shafts are arranged on the horizontal rod along its length and are coaxially connected by a coupling. The coupling is rotatably connected to the horizontal rod via a bearing seat. The synchronization gear is coaxially connected to the corresponding synchronization shaft. The synchronization rack is fixed to a fixed rod and meshes with the synchronization gear. The horizontal rod is connected to the middle of the mounting frame along its length via a connecting rod.

[0035] By adopting the above technical solution, when the lifting cylinder drives the mounting frame to lift, the synchronous gears in the two sets of synchronous components mesh with the corresponding synchronous racks to generate rotation, which transmits the lifting motion to the synchronous shaft. The two synchronous shafts rotate synchronously through a coupling, and are then connected through a horizontal bar, a connecting rod, and the middle of the mounting frame along its length, thereby improving the synchronicity of the lifting at both ends of the mounting frame and the overall stability of the lifting of the mounting frame, thus further improving the stability of the billet when it is transported and moved.

[0036] Furthermore, the mounting frame is provided with a first detection component, a second detection component, and a third detection component;

[0037] The first detection component includes a first detection plate and a first sensor. The first detection plate is disposed opposite to each other on both sides of the mounting frame in the width direction. The first sensor is disposed on the first detection plate and is used to detect whether there is a blank on the support frame.

[0038] The second detection component includes a second detection plate and a second sensor. The second detection plate is disposed opposite to the two transport rods on opposite sides. The second sensor is disposed on the second detection plate. The second sensor is used to detect whether a support rod is inserted into the support tube of the support frame below the support frame to be placed.

[0039] The crossbeam is provided with stiffening plates. The third detection component includes a third detection plate and a third sensor. The third detection plate is disposed on both sides of the width direction of the mounting frame. The third sensor is disposed on the third detection plate. The third sensor is used to detect whether there are stiffening plates on the corresponding crossbeam.

[0040] By adopting the above technical solution, the possibility of empty transport of palletizing equipment is reduced by detecting whether there is a blank on the support frame through the first detection component.

[0041] The second detection component detects whether a support rod is inserted into the support tube of the support frame below the support frame to be placed, which reduces the possibility of the support rod being lost and the possibility that the support frame and the billet on the support frame will be directly pressed down on the billet below due to the lack of a support rod, thereby further improving the protection of the billet.

[0042] The third detection component checks whether there are stiffening plates on the crossbeam to ensure the strength of the crossbeam and reduce the possibility that the crossbeam will not be able to support itself due to the lack of stiffening plates.

[0043] In summary, this application includes at least one of the following beneficial technical effects:

[0044] 1. By setting up a support mechanism, it is not easy for adjacent blanks to be squeezed during the stacking process. The pressure is transferred to the support frame through the support rods and support pipes, which avoids damage to the blanks located below. Furthermore, the connection between the support rods and support pipes also improves the stability of the blank stacking process. The transport rods move the blanks through the moving crossbeams, eliminating the need to consider the control of the transport force and avoiding damage to the blanks during transport. In summary, this greatly reduces the possibility of damage to the blanks during stacking and provides multi-faceted protection for the block blanks.

[0045] 2. The setting of multiple sets of handling components improves the stability of the billet being handled and moved. The telescopic cylinder drives the transmission rod to slide along its own axis, driving multiple sets of handling components on each side of the support frame to move synchronously. This improves the synchronicity of the rotation of multiple sets of handling rods on the mounting frame. Furthermore, with a simple structure of the cooperation between the rotating component and the transmission rod, multiple sets of handling components can be driven by only one telescopic cylinder, which is energy-saving and environmentally friendly.

[0046] 3. The storage components reduce the possibility of support rods being lost due to misplacement, and the pneumatic grippers, driven by the moving mechanism, can control the accuracy of each support rod's alignment with the support tube, improving the consistency of the support rods' height after insertion into the support tube on the same support frame.

[0053] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0054] This application discloses a stacking device for aerated concrete billets.

[0055] Reference Figure 1 The stacking equipment for aerated concrete blanks includes a fixed frame 1, on which a support mechanism 2 and a handling mechanism 3 are provided. The support mechanism 2 is used in conjunction with the blank 11 to provide support for the stacking of the blanks 11. The handling mechanism 3 is used to handle the support mechanism 2 and the blank 11.

[0056] Reference Figure 1The support mechanism 2 includes a support frame 21 and a support rod 22. One billet 11 corresponds to one support frame 21. The support frame 21 includes a base plate 211 and a crossbeam 212. The base plate 211 is composed of multiple support beams, and the crossbeam 212 is a C-shaped steel beam. The crossbeam 212 is fixedly connected to both sides of the base plate 211 in the width direction, serving to fix the base plate 211. The base plate 211 is connected to the middle of the crossbeam 212 in the width direction, and the billet 11 is placed on the base plate 211. The two ends of the support rod 22 are respectively inserted into two adjacent crossbeams 212. Each crossbeam 212 is provided with a support tube 213 that is inserted into the support rod 22. The distance between two adjacent base plates 211 is greater than the thickness of the billet 11, so that when the upper billet 11 is placed on the lower billet 11, there is no direct contact between the two adjacent billets 11 and there is space, thus preventing the lower billet 11 from being crushed.

[0057] Reference Figure 1 The conveying mechanism 3 includes a mounting frame 31, the dimensions of which are adapted to the dimensions of the support frame 21. The mounting frame 31 has a first moving direction, a second moving direction, and a third moving direction. The first moving direction is parallel to the length direction of the blank 11, the second moving direction is parallel to the width direction of the blank 11, and the third moving direction is vertical. The mounting frame 31 is externally connected to a driving device, which is used to drive the mounting frame 31 to move in the first and second moving directions. Any driving device that can enable the mounting frame 31 to move in the first and second moving directions is acceptable, and will not be described in detail here.

[0058] Reference Figure 1 and Figure 2Multiple sets of transport components 32 are installed on the mounting frame 31. The transport components 32 are located on both sides of the mounting frame 31 in the width direction, with three sets of transport components 32 equidistantly arranged on each side. This arrangement of multiple sets of transport components 32 improves the stability of the billet 11 during transport. Each transport component 32 includes two transport rods 321. A contact plate 322 is fixedly connected to the bottom of each transport rod 321. The contact plate 322 is located on the side where the two transport rods 321 are close to each other. The transport component 32 can move with the mounting frame 31 until the top surface of the contact plate 322 contacts the bottom surface of the crossbeam 212. A rotating component 33 is also installed on the mounting frame 31 to drive the transport rods 321 to rotate until the top surface of the contact plate 322 contacts the bottom surface of the crossbeam 212. During the horizontal movement and lifting of the transport rod 321, the straight line along the length direction of the two contact plates 322 in the same group is parallel to the straight line along the length direction of the crossbeam 212. When the transport rod 321 descends to the corresponding support frame 21, the contact plate 322 rotates until its top surface contacts the bottom surface of the crossbeam 212. One set of transport components 32 corresponds to one support rod 22. When the mounting frame 31 moves to the stacking position, the support rod 22 is located directly below the corresponding transport component 32. Furthermore, the support rod 22 is located in the middle of the two transport rods 321.

[0059] First, each blank 11 is placed on its corresponding support frame 21, and the support rod 22 is inserted into its corresponding support tube 213. When stacking the blanks 11, the drive transport assembly 32 is moved to the blank 11 to be transported, and then the drive transport assembly 32 is lowered so that the contact plate 322 is below the crossbeam 212. Then the drive transport rod 321 is rotated until the top surface of the contact plate 322 contacts the bottom surface of the crossbeam 212. After stable contact, the drive transport assembly 32 is raised and moved above the stacking position, and then the drive transport rod 321 is rotated again. The transport component 32 descends, allowing the lower end of the support tube 213 on the crossbeam 212 to connect with the top end of the corresponding support rod 22. After connection, the distance between two adjacent bottom plates 211 is greater than the thickness of the billet 11, thus preventing squeezing between adjacent billets 11 during stacking. The pressure is transferred to the support frame 21 through the support rod 22 and support tube 213, avoiding damage to the billet 11 located below. Furthermore, the connection between the support rod 22 and support tube 213 also improves the stability of the billet 11 during stacking. Moreover, the transport rod 321 moves the billet 11 by moving the crossbeam 212, eliminating the need to control the transport force and preventing damage to the billet 11 during transport. In summary, this significantly reduces the possibility of damage to the billet 11 during stacking, providing multifaceted protection for the block billet 11.

[0060] Reference Figure 1 and Figure 2The rotating assembly 33 includes a first connecting sleeve 331, a second connecting sleeve 332, and a connecting rod 333. The first connecting sleeve 331 and the second connecting sleeve 332 are coaxially and fixedly connected to two transport rods 321 in the same set of transport assemblies 32. The transport rods 321 and the mounting frame 31 are rotatably connected. A first connecting plate 3311 and a second connecting plate 3312 are fixedly connected to the peripheral side wall of the first connecting sleeve 331. The first connecting plate 3311 and the second connecting plate 3312 are located on both sides of the radial direction of the first connecting sleeve 331. A third connecting plate 3321 is connected to the peripheral side wall of the second connecting sleeve 332. The first connecting plate 3311 and its corresponding contact plate 322 are located on the same side of the radial direction of the transport rod 321. The third connecting plate 3321 and its corresponding contact plate 322 are located on the same side of the radial direction of the transport rod 321. The end of the first connecting plate 3311 away from the first connecting sleeve 331 is connected to a transmission component that drives the first connecting plate 3311 to rotate. One end of the connecting rod 333 is rotatably connected to the second connecting plate 3312, and the other end of the connecting rod 333 is rotatably connected to the third connecting plate 3321. The first connecting plate 3311 and the third connecting plate 3321 rotate in opposite directions.

[0061] Reference Figure 1 and Figure 2 A set of conveying components 32 corresponds to a set of rotating components 33. The transmission component is a transmission rod 34, which is set along the length of the support frame 21. One transmission rod 34 is set on each side of the support frame 21 in the width direction. One transmission rod 34 is simultaneously rotatably connected to the first connecting plate 3311 of multiple sets of rotating components 33 on one side of the support frame 21 in the width direction. A telescopic cylinder 35 is set on the mounting frame 31. The telescopic cylinder 35 is fixedly installed at one end of the mounting frame 31 in the length direction. The output end of the telescopic cylinder 35 is coaxially connected to the transmission rod 34. The telescopic cylinder 35 drives the transmission rod 34 to slide along its own axial direction.

[0062] When the straight line of the length direction of the two contact plates 322 in the same group is parallel to the straight line of the length direction of the crossbeam 212, the first connecting plate 3311 is located between the second connecting plate 3312 and the third connecting plate 3321, and the third connecting plate 3321 is closer to the transmission rod 34 than the second connecting plate 3312. When the contact plate 322 needs to rotate to the point where the top surface of the contact plate 322 contacts the bottom surface of the crossbeam 212, the telescopic cylinder 35 drives the transmission rod 34 to slide along its own axis, driving the first connecting plate 3311 to rotate away from the third connecting plate 3321, driving the second connecting plate 3312 to rotate towards the third connecting plate 3321, and driving the third connecting plate 3321 to rotate away from the first connecting plate 3311, thereby driving the two contact plates 322 to rotate away from each other until they can contact the bottom surface of the crossbeam 212. In this embodiment, the two contact plates 322 rotate 90 degrees away from each other.

[0063] When it is necessary to make the straight line of the length direction of the two contact plates 322 in the same group parallel to the straight line of the length direction of the crossbeam 212, that is, when it is necessary for the two contact plates 322 in the same group to rotate closer to each other, the telescopic cylinder 35 drives the transmission rod 34 to slide along its own axis, drives the first connecting plate 3311 to rotate towards the direction of the third connecting plate 3321, drives the second connecting plate 3312 to rotate away from the third connecting plate 3321, drives the third connecting plate 3321 to rotate towards the direction of the first connecting plate 3311, thereby driving the two contact plates 322 to rotate towards the direction of the two contact plates 322 to rotate closer to each other.

[0064] In summary, driven by the rotating assembly 33, the contact plate 322 is less likely to affect the stacking process when the transport rod 321 is raised and lowered. When transport is required, the contact plates 322 on the transport rods 321 of all transport assemblies 32 can rotate synchronously to contact the bottom surface of the crossbeam 212, thus minimizing the space occupied by the transport assembly 32.

[0065] Under the action of the transmission rod 34, multiple sets of handling components 32 on each side of the support frame 21 in the width direction are driven to move synchronously, which improves the synchronicity of the rotation of multiple sets of handling rods 321 on the mounting frame 31. Moreover, with a simple structure, multiple sets of handling components 32 can be driven to move by only one telescopic hydraulic cylinder 35, which is energy-saving and environmentally friendly.

[0066] Reference Figure 1 and Figure 3 A storage assembly 4 for accommodating the support rod 22 is provided on the crossbeam 212. Each support rod 22 corresponds to a set of storage assemblies 4, which are located near the corresponding support tube 213. The storage assembly 4 includes a storage plate 41. The storage plate 41 for each support rod 22 is located at both ends of the support rod 22 along its length. The support rod 22 is placed horizontally on the storage plate 41. A receiving groove is formed on the top surface of the storage plate 41. The shape of the receiving groove is adapted to the curvature of the peripheral side wall of the support rod 22. When the support rod 22 is stored, it is located in the receiving groove, which improves the stability of the support rod 22 when stored.

[0067] Reference Figure 1 , Figure 3 and Figure 4Both ends of the support rod 22 are provided with guide surfaces 221, which are conical. When the support rod 22 and the support tube 213 are inserted, the guide surfaces 221 of the support rod 22 are located inside the support tube 213 corresponding to the support rod 22. The guide surfaces 221 provide guidance and limitation for the insertion of the support rod 22 into the support tube 213, and also improve the smoothness of the insertion. Guide grooves 2131 are provided on the inner walls of the openings at both ends of the support tube 213. The guide grooves 2131 cooperate with the guide surfaces 221 of the support rod 22. The guide grooves 2131 are gradually widened from the center of the guide tube 213 along its length to both ends, further improving the smoothness of the insertion of the support rod 22 into the support tube 213.

[0068] Reference Figure 1 , Figure 3 and Figure 4 The support rod 22 has a first positioning ring plate 222 and a second positioning ring plate 223 coaxially connected to its two ends. The top of the support tube 213 passes through the corresponding crossbeam 212 and is coaxially connected to an auxiliary positioning ring plate 214. The bottom surface of the support tube 213 is connected to the inner wall of the crossbeam 212. When the support rod 22 and the support tube 213 are inserted, the first positioning ring plate 222 is located below the second positioning ring plate 223. The first positioning ring plate 222 and the auxiliary positioning ring plate 214 located below the first positioning ring plate 222 abut against each other. The top surface of the second positioning ring plate 223 abuts against the bottom surface of the crossbeam 212 located above the second positioning ring plate 223. This positioning method determines the depth to which the support rod 22 is inserted into the support tube 213 and improves the accuracy and stability of the insertion of the support rod 22 and the support tube 213.

[0069] Reference Figure 1 , Figure 3 and Figure 4 The distance between the first positioning ring plate 222 and the adjacent guide surface 221 is greater than the distance between the second positioning ring plate 223 and the adjacent guide surface 221. The guide surface 221 near the first positioning ring plate 222 forms a first guide cone 2211 at one end of the support rod 22, and the guide surface 221 near the second positioning ring plate 223 forms a second guide cone 2212 at the other end of the support rod 22. The axial length of the first guide cone 2211 is greater than the axial length of the second guide cone 2212. Since the lower end of the support rod 22 is located in the support tube 213 and provides more stable support when it is under pressure, the distance between the first positioning ring plate 222 and the adjacent guide surface 221 is set to be longer so that it is less likely to shake when heavy objects are stacked on top of the support rod 22. The upper end of the support rod 22 is for aligning the support tube 213 of the support frame 21 to be placed above it, so the distance between the second positioning ring plate 223 and the adjacent guide surface 221 is set to be shorter so as to simultaneously satisfy the requirements of stable support and easy alignment.

[0070] Reference Figure 1 , Figure 2 and Figure 5 On each side of the mounting frame 31 in the width direction, there are pneumatic grippers 5 for removing the support rod 22 from the storage plate 41 and inserting it into the support tube 213, and a movable mechanism 6 for driving the pneumatic grippers 5. The movable mechanism 6 includes a first sliding assembly 61, a second sliding assembly 62, a third sliding assembly 63, and a rotating component. The first sliding assembly 61 drives the pneumatic gripper 5 to move in a direction parallel to the length direction of the blank 11, the second sliding assembly 62 drives the pneumatic gripper 5 to move in a vertical direction, the third sliding assembly 63 drives the pneumatic gripper 5 to move in a direction parallel to the width direction of the blank 11, and the rotating component drives the pneumatic gripper 5 to rotate.

The first fixing plate 613 is slidably mounted on the first slide rail 611 via the first slider 612. The first motor 614 is fixed to the first fixing plate 613, and the output end of the first motor 614 passes through the first fixing plate 613 and is coaxially connected to the first gear 615. The output end of the first motor 614 and the first gear 615 are rotatably connected to the first fixing plate 613. The first rack 616 is fixed to the mounting frame 31 and is horizontally arranged along the length direction of the blank 11. The first rack 616 and the first gear 615 mesh. Start the first motor 614 to drive the first gear 615 to rotate. The first gear 615 slides on the first rack 616, causing the first fixed plate 613 to slide along the length of the first slide rail 611.

[0072] Reference Figure 1 , Figure 2 and Figure 5The second sliding assembly 62 includes a mounting plate 621, a second slide rail 622, a second slider 623, a second fixing plate 624, a second motor 625, a second gear 626, and a second rack 627. The second slide rail 622 is fixed to the mounting plate 621, the second slider 623 is fixed to the first fixing plate 613, and the second fixing plate 624 is fixed to the first fixing plate 613. The second slide rail 622 slides on the first fixing plate 613 with the second slider 623 carrying the mounting plate 621. The second motor 625 is fixed to the second fixing plate 624. The output end of the second motor 625 passes through the second fixing plate 624 and is coaxially connected to the second gear 626. The output end of the second motor 625 and the second gear 626 are rotatably connected to the second fixing plate 624. The second rack 627 is connected to the mounting plate 621 and is vertically arranged. The second rack 627 meshes with the second gear 626. Start the second motor 625, drive the second gear 626 to rotate, causing the second rack 627 to slide in the vertical direction, which in turn causes the mounting plate 621 to slide in the vertical direction.

[0073] Reference Figure 1 , Figure 2 and Figure 5 The third sliding assembly 63 includes a mounting base 631, a third slide rail 632, a third slider 633, a third fixing plate 634, a third motor 635, a third gear 636, and a third rack 637. The third slide rail 632 is fixed to the mounting base 631, the third slider 633 is fixed to the third fixing plate 634, and the third fixing plate 634 is fixed to the mounting plate 621. The third slide rail 632 slides on the third fixing plate 634 with the mounting base 631 via the third slider 633. The third motor 635 is fixed to the third fixing plate 634. The output end of the third motor 635 passes through the third fixing plate 634 and is coaxially connected to the third gear. The output end of the third motor 635 and the third gear 636 are rotatably connected to the third fixing plate 634. The third rack 637 is connected to the mounting base 631 and is horizontally arranged along the width direction of the blank 11. The third rack 637 meshes with the third gear 636. Start the third motor 635 to drive the third gear 636 to rotate, causing the third rack 637 to slide, which in turn drives the mounting base 631 to slide along the width direction of the blank 11.

[0074] Reference Figure 1 , Figure 2 and Figure 5 The rotating component is a rotary cylinder 64, which is mounted on the mounting base 631. The output end of the rotary cylinder 64 is connected to the pneumatic gripper 5, and the rotary cylinder 64 drives the pneumatic gripper 5 to rotate.

[0075] Before stacking the next blank 11, the pneumatic gripper 5 is driven to move to the storage assembly 4 to pick up the horizontally placed support rod 22. Then, the support rod 22 is moved upward first, and then moved away from the crossbeam 212. Then, the gripper is driven to rotate from the horizontal state to the vertical state, so that the support rod 22 is vertical. Then, the support rod 22 is moved into the support tube 213, which reduces the possibility of the support rod 22 being lost due to other placement. In addition, the movement of the moving mechanism 6 and the pneumatic gripper 5 can also control the accuracy of each support rod 22 being aligned with the support tube 213, which improves the consistency of the height of the support rods 22 on the same support frame 21 after being inserted into the support tube 213.

[0076] Reference Figure 1 The fixed frame 1 is equipped with a lifting assembly for driving the mounting frame 31 to move vertically. The lifting assembly includes lifting cylinders 12, which are located at both ends of the fixed frame 1 along its length. The output ends of the lifting cylinders 12 are connected to the mounting frame 31, and the lifting cylinders 12 operate synchronously to drive the mounting frame 31 to move stably. The fixed frame is also equipped with a synchronization assembly 7. Fixed rods 13 are vertically fixed at both ends of the fixed frame 1 along its length. Each fixed rod 13 corresponds to one set of synchronization assemblies 7, and the two sets of synchronization assemblies 7 are symmetrically arranged. A horizontal rod 14 is slidably connected between the two fixed rods 13.

[0077] Reference Figure 1 The synchronization component 7 includes a synchronization shaft 71, a synchronization gear 72, and a synchronization rack 73. Two synchronization shafts 71 are arranged on the horizontal rod 14 along its length direction. The two synchronization shafts 71 are coaxially connected by a coupling 74. The coupling 74 is rotatably connected to the horizontal rod 14 through a bearing seat 75. The synchronization gear 72 is coaxially connected to the corresponding synchronization shaft 71. The synchronization rack 73 is fixed on the fixed rod 13. The synchronization gear 72 and the synchronization rack 73 mesh. The horizontal rod 14 is connected to the middle of the mounting frame 31 along its length direction by a connecting rod 15. The connecting rod 15 includes a horizontal section 151 and a vertical section 152. The vertical section 152 is fixedly connected to the horizontal section 151 and is fixedly connected to the horizontal rod 14. The horizontal section 151 is fixedly connected to the mounting frame 31.

[0078] When the lifting cylinder 12 drives the mounting frame 31 to lift, the synchronous gears 72 in the two sets of synchronous components 7 mesh with the corresponding synchronous racks 73 to generate rotation, which transmits the lifting motion to the synchronous shafts 71. The two synchronous shafts 71 rotate synchronously through the coupling 74, and are then connected to the middle of the mounting frame 31 in the length direction through the horizontal rod 14, the connecting rod 15, and the mounting frame 31, thereby improving the synchronicity of the lifting at both ends of the mounting frame 31 and the overall stability of the lifting of the mounting frame 31, thereby further improving the stability of the blank 11 when it is transported and moved.

[0079] Reference Figure 1The mounting frame 31 is equipped with a first detection component 8, a second detection component 9, and a third detection component 10. The first detection component 8 includes a first detection plate 81 and a first sensor 82. The first detection plate 81 is disposed opposite to each other on both sides of the mounting frame 31 in the width direction. The first sensor 82 is disposed on the first detection plate 81. The first sensor 82 is a laser sensor. The laser beam of the first sensor 82 is directed toward the position where the blank 11 is placed on the support frame 21. The first sensor 82 is used to detect whether there is a blank 11 on the support frame 21 and sends the detection signal to the control system used in conjunction with it, reducing the possibility of empty transport of the palletizing equipment.

[0080] Reference Figure 1 and Figure 2 The second detection component 9 includes a second detection plate 91 and a second sensor 92. A set of conveying components 32 corresponds to a set of second detection components 9. The second detection plate 91 is disposed opposite to the two conveying rods 321 on opposite sides. The second sensor 92 is disposed on the second detection plate 91. The second sensor 92 is a laser sensor. The laser beam of the second sensor 92 is directed toward the support rod 22 to be inserted. That is, the second sensor 92 is located above the support tube 213 to be inserted. It is used to detect whether the support rod 22 is inserted into the support tube 213 of the support frame 21 below the support frame 21 to be placed, and sends the detection signal to the control system used in conjunction with it. This reduces the possibility of the support rod 22 being lost and the possibility that the support frame 21 and the blank 11 on the support frame 21 will be directly pressed onto the blank 11 below due to the absence of the support rod 22, thereby further improving the protection of the blank 11.

[0081] Reference Figure 1 The crossbeam 212 is provided with stiffening plates 2121. The third detection component 10 includes a third detection plate 101 and a third sensor 102. The third detection plate 101 is located on both sides of the width direction of the mounting frame 31. The third sensor 102 is located on the third detection plate 101. The third sensor 102 is a laser sensor. The laser beam of the third sensor 102 is directed toward the position of the stiffening plate 2121. The third sensor 102 is used to detect whether there is a stiffening plate 2121 on the corresponding crossbeam 212 and send the detection signal to the control system used in conjunction to ensure the strength of the crossbeam 212 and reduce the possibility that the crossbeam 212 will not be able to support itself due to the lack of stiffening plates 2121.

[0082] The implementation principle of a stacking device for aerated concrete billets in this application is as follows:

[0083] Before transporting the support frame 21 and blank 11 to be stacked, the pneumatic grippers 5 sequentially remove the support rods 22 from the storage plate 41. The rotary cylinder 64 rotates the support rods 22 from a horizontal to a vertical position. Then, the movable mechanism 6 moves the pneumatic grippers 5 to insert the support rods 22 into the corresponding support tubes 213, so that the first positioning ring plate 222 on the support rod 22 and the corresponding auxiliary positioning ring plate 214 abut against each other. Then, the mounting frame 31 is moved to drive the transport assembly 32 to the blank 11 to be transported. Then, the transport assembly 32 is driven to descend so that the contact plate 322 is positioned at the blank 11 to be transported. Below the crossbeam 212, the driving transport rod 321 is rotated until the top surface of the contact plate 322 contacts the bottom surface of the crossbeam 212. After stable contact, the driving transport assembly 32 is driven to rise and move above the stacking position. Then the driving transport assembly 32 is driven to fall, so that the lower end of the support tube 213 on the crossbeam 212 and the top end of the corresponding support rod 22 are inserted, so that the second positioning ring plate 223 on the corresponding support rod 22 abuts against the bottom surface of the crossbeam 212 of the support frame 21 that has just been lowered. This allows for fast and stable stacking, and the billet 11 is not easily damaged, thus protecting the billet 11.

[0084] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
