Description

Technical Field

[0001] This utility model relates to the field of billet transfer technology, and in particular to a stacking billet turning platform. Background Technology

[0002] In the field of aerated concrete production, after the billets are cut and stacked, they need to be flipped and adjusted to adapt to subsequent autoclaving, finished product stacking and other processes. At the same time, it is necessary to achieve the orderly transfer of multiple independent billets after stacking. This step is the key to ensuring the continuity of aerated concrete production and product quality.

[0003] Currently, the aerated concrete industry faces significant shortcomings in its processing technology for stacked billets. On the one hand, existing turning equipment is mostly a large-scale turning structure designed for whole stacks of uncut billets, capable only of overall posture adjustment and unable to meet the synchronous turning requirements of multiple small stacks of billets after stacking. If a 90° turn is required for the stacked billets (such as turning vertically cut billets into horizontal ones for curing), it requires manual stack-by-stack operation or breaking it down into multiple separate turning processes. This not only results in low single-processing efficiency, making it difficult to match the high-capacity requirements of aerated concrete production lines, but also easily leads to damage to the edges and corners of the billets and cracking of the internal loose structure due to manual contact or uneven turning force, significantly increasing the defect rate. The loose texture and low strength of aerated concrete billets further amplify the shortcomings of existing turning methods.

[0004] On the other hand, the existing conveying and flipping functions are disconnected. The stacked blanks must first be transferred to an independent flipping station via conveyor belt, and then transferred to the next process after flipping. There is a clear discontinuity in the process connection. Moreover, due to the lack of a dedicated positioning and fixing structure for the stacked blanks, the stacks of blanks are prone to shifting due to vibration during the conveying process, and the stacks may also scatter during flipping. Additional manual calibration and sorting are required, which further prolongs the production cycle and increases labor costs.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a stacking platform for blanks, making it more valuable for industrial use. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a stacking platform for blanks.

[0007] The present invention provides a stacking platform for blanks, including a support installed on a foundation, a base plate that can be rotated 90° on the support, and a conveyor frame that can be rotated 90°. The surface of the conveyor frame is provided with multiple pallets for stacking blanks placed at intervals, and the pallets can be fixed on the conveyor frame.

[0008] This stacking billet turning platform includes a support frame installed on the foundation. The support frame is equipped with a base plate for supporting the billets and a conveyor frame for transporting the billets. Both can be turned over to adjust the posture of the billets. The surface of the conveyor frame is arranged with multiple trays for individually supporting the stacked billets. The trays can be firmly fixed on the conveyor frame to ensure that the billets remain stable during the turning and transporting process.

[0009] Furthermore, support frames are installed on both sides of the bracket for support. The support frames are movably connected to the first hydraulic cylinder via shafts. The telescopic rod of the first hydraulic cylinder is movably connected to the base plate. The outer side of the base plate is movably connected to the tail end of the second hydraulic cylinder via shafts. The telescopic rod of the second hydraulic cylinder is movably connected to the conveyor frame. The first and second hydraulic cylinders drive the flipping motion of the base plate and the conveyor frame respectively.

[0010] The support frame is equipped with support frames on both sides to provide stable support. The support frames are connected to the first hydraulic cylinder via shafts and can move flexibly. The extension rod of the first hydraulic cylinder is connected to the base plate to transmit driving force. The outer side of the base plate is connected to the tail end of the second hydraulic cylinder via shafts. The extension rod of the second hydraulic cylinder is connected to the conveyor frame. With the power output of the first and second hydraulic cylinders, the base plate and the conveyor frame are driven to complete the flipping action, ensuring that the flipping process is stable and controllable.

[0011] Furthermore, the conveyor frame includes a drive motor installed at one end, which drives two sets of parallel conveyor belts mounted on the conveyor frame to rotate synchronously via a reducer and a shaft, with pallets placed on the conveyor belts.

[0012] One end of the conveyor frame is equipped with a drive motor that provides power. The drive motor transmits power through the cooperation of the reducer and the shaft, driving the two sets of conveyor belts installed on the conveyor frame to rotate in parallel and synchronously. The pallet is placed on the conveyor belt, and the rotation of the conveyor belt enables the pallet and the stacked blanks to be transported smoothly, ensuring that the blanks are transferred in an orderly and efficient manner.

[0013] Furthermore, multiple crossbeams are evenly arranged in the middle of the conveyor frame, and guide brackets in the same direction as the conveyor frame are installed on the crossbeams. The tray has a guide plate in the middle that can be inserted into the guide bracket.

[0014] Multiple crossbeams that serve as load-bearing and reinforcement are evenly arranged in the middle of the conveyor frame. Guide brackets that are aligned with the direction of the conveyor frame are installed on the crossbeams. The pallet is equipped with a matching guide plate in the middle. The guide plate can be precisely inserted into the guide bracket to provide stable guidance for the pallet during conveying and flipping, preventing the pallet from shifting or shaking, and ensuring the stability of the stacked blanks.

[0015] Furthermore, a clamping cylinder is installed on each crossbeam, and a through hole is provided in the same direction as the crossbeam on the guide bracket. The through hole is used for the telescopic rod of the clamping cylinder to pass through. The telescopic rod of the clamping cylinder can press against the side wall of the guide plate of the pallet, pressing the pallet against the guide bracket.

[0016] Each crossbeam is equipped with a clamping cylinder. The guide bracket has a matching through hole in the same direction as the crossbeam. The telescopic rod of the clamping cylinder can pass through smoothly. When the clamping cylinder is working, its telescopic rod can press tightly against the side wall of the guide plate of the pallet, thereby firmly pressing the pallet onto the guide bracket. This further improves the fixing effect of the pallet during the flipping and conveying process and prevents the stacked blanks from shifting or falling due to loosening.

[0017] Furthermore, multiple sets of pallet limiters are installed on the inner wall of the conveyor frame. Each set of pallet limiters includes two limit cylinders fixed to the inner side wall of the conveyor frame. A plate-shaped limit head is fixed on the telescopic rod of the limit cylinder, and the limit head can contact the end side wall of the pallet.

[0018] Multiple sets of pallet limiters are installed on the inner wall of the conveyor frame. Each set of pallet limiters consists of two limit cylinders fixed to the inner wall of the conveyor frame. The telescopic rod of the limit cylinder is equipped with a plate-shaped limit head. Through the precise fit between the limit head and the end side wall of the pallet, multiple pallets can be effectively separated to ensure that the pallets are evenly spaced. At the same time, the movement direction of the pallets can be strictly limited to prevent the pallets from moving axially during the conveying process. This ensures that the pallets move smoothly along the set trajectory and meets the orderly bearing requirements of the stacked blanks.

[0019] By means of the above-described solution, the present invention has at least the following advantages: It adapts to the need for synchronous flipping of stacked billets, solving the problem that existing equipment cannot simultaneously flip multiple independent billets after stacking. The first and second hydraulic cylinders drive the base plate and conveyor frame to flip, eliminating the need for manual operation of each stack, greatly improving the flipping efficiency. At the same time, it avoids billet damage caused by manual contact or uneven force, which is in line with the characteristics of aerated concrete billets, which are loose in texture and have low strength, effectively reducing the defect rate.

[0020] The system integrates flipping and conveying functions, allowing stacked blanks to be adjusted in posture and transferred in an orderly manner on the same equipment. This eliminates the disconnect caused by the separation of flipping and conveying processes in existing technologies, eliminating the need for additional transfer and calibration steps, shortening the production cycle, reducing labor costs, and meeting the requirements for continuous and automated production lines.

[0021] The pallet positioning and fixing structure is well-developed. The guide bracket and pallet guide plate work together to achieve guiding and limiting. The clamping cylinder further secures the pallet. Combined with the separation and movement direction restriction function of the pallet limiter, multiple guarantees ensure that the pallet and the billet it carries do not deviate, move, or scatter during the flipping and conveying process. This significantly improves the stability and accuracy of billet transfer and facilitates precise connection with subsequent autoclaving, finished product stacking and other processes.

[0022] The overall structural design is adapted to the high-capacity requirements of aerated concrete production. The components work together to achieve efficient processing of stacked blanks. The equipment operates smoothly and controllably, and can be adapted to stacked blanks of different specifications without complicated debugging, thereby improving the equipment's versatility and industrial utilization value and helping to upgrade the production line to automation.

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0027] See Figure 1 and Figure 2When this stacking and turning platform is in operation, the stacked aerated concrete billets are first placed on the base plate 2 on the support 1 for initial bearing. Then, the conveyor frame 3 drives the spaced pallets 4 on its surface to rotate 90°, so that the pallets 4 precisely fit the outside of the billet to form a stable support. Then, the base plate 2 and the conveyor frame 3 rotate 90° simultaneously, transferring the billet smoothly onto the pallet 4. The pallet 4 is fixed on the conveyor frame 3 to prevent the billet from shifting. Finally, the base plate 2, after the billet transfer is completed, returns to its initial position, and the next round of billet turning operation can begin. The design of the pallets 4 first fitting and then rotating synchronously is suitable for the loose texture of aerated concrete billets, avoiding damage to the billets during the turning process. The coordinated action of the base plate 2 and the conveyor frame 3 achieves seamless connection of billet transfer without manual adjustment. The spacing of the pallets 4 is adapted to the synchronous processing needs of multiple sets of billets after stacking. The stable installation of the support 1 ensures stable operation of the equipment, greatly improving the turning efficiency and billet transfer accuracy.

[0028] See Figure 3 After being stacked, the aerated concrete billets are first placed on the base plate 2 of the support 1. The support frames 5 on both sides of the support 1 provide stable support for the overall structure. When it is necessary to flip, the first hydraulic cylinder 6, which is movably connected to the support frame 5 via a shaft, is activated. Its extension rod pushes the base plate 2 to begin flipping. At the same time, the second hydraulic cylinder 7, which is movably connected to the outside of the base plate 2 via a shaft, moves synchronously. Its extension rod drives the conveyor frame 3 to flip, realizing the coordinated flipping movement of the base plate 2 and the conveyor frame 3. After the billet completes the posture adjustment and is transferred to the pallet 4 of the conveyor frame 3, the extension rods of the first hydraulic cylinder 6 and the second hydraulic cylinder 7 extend... The retracting rod resets, driving the base plate 2 and conveyor frame 3 back to their initial positions, completing one round of operation. The support frame 5 ensures structural stability during the flipping process. The first hydraulic cylinder 6 and the second hydraulic cylinder 7 independently drive the base plate 2 and conveyor frame 3, allowing flexible control of their flipping rhythm and angle. The shaft connection method makes the movement of each component smoother, avoiding jamming, effectively improving the accuracy and stability of the flipping action, reducing damage to the aerated concrete billet caused by flipping and shaking, and eliminating the need for manual assistance, thus adapting to the automation requirements of the production line and significantly improving production efficiency.

[0029] See Figure 2After the billet is flipped and transferred to the pallet 4, the drive motor 8 installed at one end of the conveyor frame 3 starts. The power output of the drive motor 8 is transmitted through the reducer and shaft, driving the two sets of parallel conveyor belts 9 on the conveyor frame 3 to rotate synchronously and smoothly. The pallet 4 placed on the conveyor belt 9 moves synchronously with the rotation of the conveyor belt 9, thereby accurately transferring the stacked aerated concrete billets carried on the pallet 4 to the next process. After the billet is transported, the drive motor 8 stops working, and the conveyor belt 9 and the pallet 4 return to their initial positions, ready for the next round of transport. The drive motor 8 provides stable power, and the transmission structure of the reducer and shaft ensures that the two sets of conveyor belts 9 operate synchronously, avoiding deviation or jamming during the transport of the pallet 4 and the billet. The cooperation between the pallet 4 and the conveyor belt 9 makes the transport of the stacked billets more orderly, adapting to the continuous transfer needs of multiple sets of billets. No manual handling is required, which not only improves the transport efficiency, but also reduces the damage to the billets caused by manual contact or unstable transport, helping the production line to achieve automated continuous operation.

[0030] See Figure 5 Before the pallet 4 carries the stacked aerated concrete billets for conveying or flipping, the guide plate 12 in the middle of the pallet 4 is precisely inserted into the guide bracket 11 installed on the crossbeam 10 evenly arranged in the middle of the conveyor frame 3, which is in the same direction as the conveyor frame 3. Subsequently, when the pallet 4 is conveyed by the conveyor belt 9 or flipped by the conveyor frame 3, the guide plate 12 always remains in close contact and slides within the guide bracket 11, ensuring that the pallet 4 moves along the set trajectory. The crossbeam 10 provides a stable installation base for the guide bracket 11. The guide bracket 11 and the guide plate 12 of the pallet 4 form a precise fit, which can effectively limit the lateral displacement and shaking of the pallet 4 during the conveying and flipping process, so that the billets on the pallet 4 always maintain a regular posture, avoiding the collision and damage of the billets due to the displacement of the pallet 4. At the same time, it adapts to the synchronous processing requirements of multiple sets of billets after stacking, improves the stability of equipment operation and the accuracy of billet transfer, and ensures the continuous and efficient operation of the production line.

[0031] See Figure 5When the guide plate 12 in the middle of the pallet 4 is engaged with the guide bracket 11 on the crossbeam 10 in the middle of the conveyor frame 3, the clamping cylinder 13 installed on each crossbeam 10 is activated. The telescopic rod with anti-slip block at its end passes through the through hole set in the same direction as the guide bracket 11 and the crossbeam 10. The anti-slip block is tightly attached to the side wall of the guide plate 12 of the pallet 4 and applies lateral clamping force. This not only firmly presses the pallet 4 against the inner side wall of the guide bracket 11, but also reliably locks the pallet 4 after it is flipped, preventing the pallet 4 from shifting due to force during the flipping process. After the billet has completed the conveying or flipping operation, the telescopic rod of the clamping cylinder 13 retracts and resets, and the anti-slip block disengages from the guide plate 12. The clamping and locking of the pallet 4 is released in one step; the anti-slip block at the end of the clamping cylinder 13 increases the friction with the guide plate 12, and the lateral clamping force and locking function provide dual protection for the fixing effect of the pallet 4, effectively preventing the pallet 4 from loosening, shifting or moving under high-speed conveying and flipping conditions. It is especially suitable for the loose texture of aerated concrete billets, minimizing the collision damage to the billets caused by the swaying of the pallet. The crossbeam 10 provides a stable installation base for the clamping cylinder 13, and the through hole ensures the accurate application of pressure and locking trajectory of the telescopic rod. The cooperation between the guide bracket 11 and the guide plate 12 further improves the positioning accuracy. Multiple protections make the billet transfer more stable and reliable, and help the production line operate continuously and efficiently.

[0032] Before the aerated concrete billets, after being stacked, are conveyed or flipped on pallet 4, multiple sets of pallet limiters installed on the inner wall of conveyor frame 3 are activated simultaneously. In each set of pallet limiters, two limit cylinders 14 fixed to the inner wall of conveyor frame 3 drive their telescopic rods to extend, causing the plate-shaped limit heads 15 on the telescopic rods to precisely fit against the end sidewall of pallet 4, strictly limiting the movement direction of pallet 4. After the billets have completed the conveying or flipping operation, the telescopic rods of the limit cylinders 14 retract, and the limit heads 15 disengage from the end of pallet 4, releasing the limit. The multiple sets of pallet limiters, through the limit cylinders 14… The precise contact between the drive limiting head 15 and the end of the pallet 4 effectively separates multiple pallets 4, ensuring that the pallets 4 are evenly spaced, and strictly limits the axial movement of the pallets 4, preventing displacement and collision during conveying or flipping. It is especially suitable for the synchronous processing requirements of multiple groups of blanks after stacking. The extension and retraction action of the limiting cylinder 14 is responsive and precise. The plate-shaped limiting head 15 increases the contact area with the pallet 4, making the limiting more stable and reliable, further improving the stability and orderliness of blank transfer, reducing the risk of blank breakage, and ensuring the continuous and efficient operation of the production line.
