Description

Technical Field

[0001] This application relates to the field of brick production equipment technology, and more specifically, to a palletizer with a palletizing mechanism. Background Technology

[0002] A brick stacking machine is an intelligent piece of equipment used in the building materials industry, integrating mechanical, electrical, and automated control technologies. It is primarily used to neatly and orderly stack bricks, after they have been fired or formed on the production line, onto pallets, transport vehicles, or designated areas through operations such as gripping, handling, and stacking. Using robotic arms, conveyor belts, suction cups, or grippers, along with sensors and a control system, it can precisely position bricks and quickly and efficiently complete the brick stacking task according to a preset stacking pattern.

[0003] A search revealed that patent CN219906112U discloses a palletizer with a palletizing mechanism, including an operating table. A conveying mechanism is fixedly installed on the upper surface of the operating table. Support plates are linearly arranged on the upper surface of the conveying mechanism. Bricks are placed in a rectangular array at intervals on the upper surface of the support plates. An integrated component corresponding to the support plates and the bricks thereon is fixed on one side of the upper surface of the conveying mechanism. A rotating component one is installed on the upper surface of the operating table. A rotating component two is installed on one side of the upper surface of the rotating component one. A lifting component is installed at the bottom of the rotating component two. This palletizer with a palletizing mechanism has a reasonable and practical structure and is easy to operate. Through the coordinated action of the conveying mechanism, the integrated component, the rotating component one, the rotating component two, the lifting component, and the adsorption component, it can automatically and efficiently perform brick palletizing and unloading operations. It reduces labor intensity, saves time and effort, improves work efficiency, and greatly reduces labor costs, bringing convenience to production and processing.

[0004] The aforementioned patent uses a U-shaped fixing frame to laterally intercept multiple bricks on the support plate. At the same time, two electric telescopic rods drive two symmetrical push plates to move towards each other to integrate and gather the multiple bricks. Since there is no interception structure on the other side of the U-shaped fixing frame, the bricks are prone to pop out, tilt, or shift from the unintercepted side under the pushing force of the push plates during integration, resulting in integration failure and affecting stacking efficiency and quality.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figures 1-7 A palletizer with a palletizing mechanism includes a workbench and a conveyor belt 1 set on the workbench. The top of the conveyor belt 1 is provided with multiple placement plates 4, and a fixing frame 2 is provided on one side of the conveyor belt 1. An integrated component is provided inside the fixing frame 2.

[0030] The integration component includes a first integration plate 12 and a second integration plate 13. A movable plate 5 is provided on one side of the fixed frame 2. A first electric push rod 8 is provided inside the movable plate 5. The first electric push rod 8 is used to drive the first integration plate 12 and the second integration plate 13 to integrate and gather the bricks.

[0031] Reference Figures 1-7 A fixed frame 2 is fixedly installed on the top of the workbench. A cylinder 6 is fixedly connected to the top of the fixed frame 2. The output end of the cylinder 6 passes through the top of the fixed frame 2 and is fixedly connected to the top of the movable plate 5. A cavity 7 is opened inside the movable plate 5. A first electric push rod 8 is welded to the inner top wall of the cavity 7. A mounting base 9 is fixedly connected to the output end of the first electric push rod 8. A plurality of connecting rods 10 are provided on the outer wall of the mounting base 9. The top end of each connecting rod 10 is rotatably connected to the outer wall of the mounting base 9. A plurality of limiting through grooves 14 are opened on the inner bottom wall of the cavity 7. A connecting seat 11 is slidably connected inside the plurality of limiting through grooves 14. The bottom ends of the plurality of connecting rods 10 are rotatably connected to the corresponding connecting seat 11. The number of first integrated plates 12 and second integrated plates 13 is set to two. The two first integrated plates 12 and the two second integrated plates 13 are symmetrically arranged. The cross-sectional shape of each first integrated plate 12 is I-shaped. The cross-sectional shape of each second integrated plate 13 is I-shaped. Each first integrated plate 12 is inserted into the two second integrated plates 13.

[0032] The integration component allows multiple bricks to be integrated and gathered together. Specifically, the bricks are first evenly placed on the placement plate 4. When integration is needed, cylinder 6 is activated, its output end pushing the moving plate 5 up and down along the fixed frame 2 to adjust the height of the integration component to a suitable position. Subsequently, the output end of the first electric push rod 8 retracts, pushing the mounting base 9 upwards. Because the top end of the connecting rod 10 is rotatably connected to the mounting base 9 and the bottom end is rotatably connected to the connecting seat 11, and the connecting seat 11 slides within the limiting groove 14, the upper part of the mounting base 9... The moving connecting rod 10 pushes the connecting seat 11 to move inward within the limiting groove 14, thereby causing the first integrating plate 12 and the second integrating plate 13 to move inward simultaneously. Because the first integrating plate 12 and the second integrating plate 13 are symmetrically arranged, and the first integrating plate 12 is I-shaped and the second integrating plate 13 is straight and interlocked with each other, during the upward movement, the two sets of first integrating plates 12 and second integrating plates 13 move towards each other from both sides of the brick, gathering and integrating the bricks towards the middle, thereby integrating multiple bricks into a regular rectangular stack, so that the subsequent palletizer body 3 can discharge and stack the bricks.

[0033] By integrating components, multiple bricks on the placement plate 4 can be precisely gathered and integrated, and arranged into a rectangular stack. This significantly improves the neatness and stability of the brick stack, providing a standardized unit for the subsequent material output and stacking of the palletizer body 1. This effectively reduces problems such as stacking misalignment and tilting, and improves stacking efficiency and quality. At the same time, the plug-in design and symmetrical layout of the first integration plate 12 and the second integration plate 13 can adapt to the integration needs of bricks of different specifications, enhance the versatility of the equipment, and ensure that the bricks are subjected to uniform force during the integration process, reducing the risk of brick breakage, reducing material loss, and ensuring the integration effect and equipment operation reliability.

[0034] The lengths of the multiple connecting rods 10 can be set according to the size of the bricks and the integration requirements. This allows the two first integrating plates 12 and the second integrating plate 13 to integrate the bricks into different rectangles and squares when they are brought together. For example, when the bricks on the conveyor belt are small standard bricks (60mm × 120mm) and need to be stacked in a square, the connecting rods 10 can be set to a shorter length. This allows for precise control of the four sides of the bricks to align when the two first integrating plates 12 and the second integrating plate 13 are brought together, forming a 360mm side length (3 bricks). Square stacks (length or width of 6 bricks) are convenient for subsequent forklift handling; if the bricks are large hollow bricks (190mm×390mm), and need to be integrated into rectangular stacks according to storage space requirements, then the two sets of symmetrical connecting rods 10 are set to different lengths, so that the first integrating plate 12 and the second integrating plate 13 arrange the bricks into a rectangular stack with a length of 780mm (length of 2 bricks) and a width of 570mm (width of 3 bricks) during the movement, which can improve space utilization and meet the loading needs of different transportation equipment.

[0035] Reference Figures 1-5 A motor 18 is fixedly connected to the top of the workbench. The output end of the motor 18 is fixedly connected to the palletizer body 3. A second electric push rod 19 is fixedly connected to one side of the palletizer body 3. The output end of the second electric push rod 19 passes through one side of the palletizer body 3 and is fixedly connected to a movable bracket 20. A third electric push rod 21 is fixedly connected to both sides of the bottom of the movable bracket 20. A clamping plate 22 is fixedly connected to the output end of each third electric push rod 21. A stacking plate 23 is provided on one side of the workbench.

[0036] The palletizer body 3 enables automated palletizing. Specifically, after the bricks are assembled into a regular rectangular stack by the integration components, the motor 18 starts, rotating the palletizer body 3 to the corresponding placement plate 4 and adjusting it to a suitable position. Then, the second electric push rod 19 extends, pushing the moving bracket 20 to move, positioning the two clamping plates 22 on both sides of the brick stack. Next, the third electric push rod 21 extends, driving the clamping plates 22 to clamp and fix the brick stack. After clamping, the second electric push rod 19 retracts, moving the moving bracket 20 and the clamped brick stack towards the palletizer body 3, detaching it from the placement plate 4. At this point, the motor 18 rotates again, driving the palletizer body 3 to transport the brick stack to the stacking plate 23 on one side of the workbench. After adjusting to the predetermined height and position, the third electric push rod 21 retracts, releasing the clamping plates 22 and placing the brick stack smoothly on the stacking plate 23. This cycle continues, continuously completing the automated palletizing operation.

[0037] The palletizer body 3 enables fully automated operation of bricks from grabbing, handling to stacking, effectively replacing heavy manual labor and greatly improving palletizing efficiency. Compared with traditional manual palletizing, it improves work efficiency, shortens the production cycle, and ensures the neatness and stability of the palletizing, reducing transportation damage and storage space waste caused by irregular palletizing.

[0038] Reference Figure 4 and Figure 5 Each of the first integrated plate 12, the second integrated plate 13, and the clamping plate 22 has a pressure sensor 15 embedded in the side of the brick. One of the first integrated plates 12 has a displacement sensor 16 at the bottom and a vision sensor 17 is provided on one side of the inner wall of the fixing frame 2.

[0039] First, a pressure sensor 15 is embedded in the first integrated plate 12, the second integrated plate 13, and the clamping plate 22 on the side close to the brick. When the integrated plate or clamping plate contacts the brick, the pressure sensor 15 detects the contact pressure in real time and converts it into an electrical signal. The signal is transmitted to the analog input module of the PLC through a shielded cable. The PLC compares the signal with a preset threshold and controls the first electric push rod 8 and the third electric push rod 21 to prevent excessive or insufficient pressure.

[0040] Secondly, a displacement sensor 16 is installed at the bottom of the first integrated plate 12. The distance between the integrated plate and the brick is monitored in real time using the laser ranging principle. The sensor outputs a digital signal to the communication module of the PLC to precisely control the descent height of the integrated plate and ensure accurate contact with the surface of the brick.

[0041] Finally, the vision sensor 17 is fixed to the inner wall of the mounting frame 2 and communicates with the PLC via industrial Ethernet to continuously scan the position and direction of the bricks on the conveyor belt. After processing by the built-in algorithm, the data (such as center coordinates and angle deviation) is sent to the PLC to guide the palletizer body 3 to accurately pick up the bricks. The three work together to achieve closed-loop control, improving palletizing accuracy and reliability.

[0042] The pressure sensor 15, displacement sensor 16 and vision sensor 17 mentioned above are all mature existing technologies in this field. Their connection methods will not be described in detail here, and the specific structural diagram is not shown.

[0043] Working principle: After the bricks are conveyed to the placement plate 4 by the conveyor belt 1, the vision sensor 17 scans the position, direction and arrangement of the bricks in real time and transmits the data to the PLC control system. The PLC determines whether to start the integration operation according to the preset program. If integration is required, the cylinder 6 moves first to push the moving plate 5 to adjust the integration component to a suitable height. Then the first electric push rod 8 retracts, and through the linkage of the connecting rod 10 and the connecting seat 11, it drives the first integration plate 12 and the second integration plate 13 to move inward to gather the bricks. During this process, the pressure sensor 15 monitors the pressure between the integration plate and the bricks in real time and feeds it back to the PLC to adjust the extension and retraction of the first electric push rod 8 to prevent the bricks from being squeezed and damaged. The displacement sensor 16 precisely controls the descent height of the integration plate to ensure that the integration action is executed accurately. Once the bricks are assembled into a neat stack, the motor 18 drives the palletizer body 3 to rotate to the corresponding position. The second electric push rod 19 and the third electric push rod 21 move in sequence, driving the clamping plate 22 to clamp the brick stack and transport it to the stacking plate 23. During the transport process, the pressure sensor 15 continuously monitors the clamping force of the clamping plate to ensure stable transport of the bricks.

[0044] 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.
