Description

Technical Field

[0001] This invention belongs to the technical field of pallet processing equipment, specifically relating to a pallet stacking machine. Background Technology

[0002] Wooden pallets are pallets made from natural wood and are widely used in the containerization, stacking, handling, and transportation of goods. Common pallets are generally composed of wooden strips and blocks. The longer the wooden strips, the more blocks are evenly attached to the bottom, primarily for stable support. Current technology often uses manual nailing with a handheld nail gun to nail the wooden strips and blocks, which is inefficient. Therefore, patent CN220903620U discloses a pallet stacking machine, including a frame, a base plate on the frame, chain assemblies on both sides of the base plate, and a chain assembly above the chain assemblies. The system consists of a square timber bin assembly, a timber strip bin assembly, a column assembly, and a pneumatic nail gun assembly, arranged sequentially from front to back. A protective cover is located at the front end of the chain assembly, and a conveyor assembly is located at the rear end. An air tank is positioned above the column assembly. The square timber bin assembly and the timber strip bin assembly facilitate the loading of timber blocks and strips. The chain assembly facilitates the transfer of timber blocks and strips. The pneumatic nail gun assembly enables automatic binding of combined timber blocks and strips, improving binding accuracy. Multiple timber strip bin assemblies and material stoppers are provided, allowing for simultaneous loading of multiple timber blocks. The number of pneumatic nail guns is the same as the number of timber strip bin assemblies, enabling simultaneous binding of multiple timber blocks and improving work efficiency.

[0003] However, the above-mentioned method can only cut and position one set of wooden strips and blocks during the nailing process, and cannot nail multiple sets of pallets at once. Therefore, a pallet stacking machine that can nail multiple sets of pallets at once is designed to improve nailing accuracy and quality. Summary of the Invention

[0004] The purpose of this invention is to provide a pallet stacking machine and its control method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pallet jacking machine, comprising a frame, a motor mounted on the left side of the frame, and symmetrical rotating rods arranged on the right side of the frame. A belt connects the rotating rods to the output shaft of the motor. A secondary support is mounted between the tops of the belts. A positioning component is provided on the top of the secondary support. A gantry frame is mounted and connected between the front and rear of the middle of the frame. A first guide rail is provided on the right side of the gantry frame. A connecting support is slidably mounted on the first guide rail. Multiple pneumatic nail guns are slidably mounted on the right side of the connecting support via multiple second guide rails.

[0006] Preferably, a first cylinder is fixedly installed on the left side of the gantry frame, the output end of the first cylinder is connected to the connecting support, and a second cylinder with the same number as the number of pneumatic nail guns is provided on the top of the connecting support, the output end of the second cylinder is connected to the pneumatic nail gun.

[0007] Preferably, the positioning component has multiple square plates, each of which has three flow grooves. A rear positioning plate is provided on the square plate at the rear side of the flow grooves. A flow rail is provided at the bottom of the square plate through multiple connecting frames. Three front positioning plates are slidably provided on the flow rails. The front positioning plates are respectively located in the flow grooves. A coupling extends between the lower parts of the front positioning plates. A first push rod is provided at the front side of the bottom of the square plate.

[0008] Preferably, the number of square plates is 3, which are arranged from left to right as a first square plate, a second square plate and a third square plate. The first square plate has a left side positioning plate on its left side, the second square plate has a middle side positioning plate, and the third square plate has a right side positioning plate that slides on the top right side via a second push rod.

[0009] Preferably, the top inner sides of both the first square plate and the third third plate are provided with three first push plates.

[0010] Preferably, the first square plate and the third square plate are provided with two second push plates on the inner side of the top, the second push plates are provided with clamping blocks on the top, the clamping blocks are connected by a horizontal plate, and the horizontal plate is provided with three plate positioning blocks on the top.

[0011] Preferably, the bottom of the first square plate and the third third plate are provided with a main drive cylinder and a rear drive cylinder from back to front. The output rods of the main drive cylinder and the rear drive cylinder pass through the first square plate and the third third third plate, and are rotatably connected to a roller assembly at the top via a hinge seat.

[0012] Preferably, the top of the frame is provided with circular rails on both the front and rear sides, and the sub-support is provided with symmetrical wheels on both the front and rear sides.

[0013] Preferably, multiple air tanks are installed on the rear side of the frame, and the air tanks provide air for the first cylinder, the second cylinder, the first push rod, the second push rod, etc.

[0014] A control method for a pallet stacking machine includes the following steps:

[0015] S01: Place the wooden block between the front positioning plate, the rear positioning plate and each side positioning plate;

[0016] S02: Place the wooden strip between the board positioning block, the front positioning plate, the left side positioning plate, and the right side positioning plate;

[0017] S03: Connect the power to start the jacking machine, open the human-machine interface (HMI), check the working air pressure of the machine to see if it is between 0.7Mpa and 0.8Mpa, then enter the "debugging screen" to check if each pneumatic component is in normal operating condition.

[0018] S05: Return to the main page to check if the motor is at the zero point, that is, whether the current position is displayed as 0. If not, first click the "Reset" button, then click the "Return to Origin" button. Motor 2 will automatically find the operating zero point until the current position is displayed as 0.

[0019] S06: After inspecting the above components, adjust and input the parameters in the "Parameter Setting" screen, and select the required nail position formula;

[0020] S07: The motor drives the wooden blocks and strips to move to the left, while the pneumatic nail gun nails the wooden blocks according to the nail position formula until all the wooden block points are nailed, thus obtaining the pallet.

[0021] S08: The motor reverses its operation, driving the auxiliary support and tray to move to the right and return to the origin of motion until they stop moving;

[0022] S09: The system detects that the motor has stopped operating, and starts the main drive cylinder and the rear drive cylinder to lift upward, so that the roller assembly is in a forward tilted state;

[0023] S10: The tray falls forward along the roller assembly, completing the collection, and the main drive cylinder and the rear drive cylinder are reset.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention enables the installation of a movable pneumatic nail gun on the gantry frame, allowing for multi-hole nailing between individual wooden blocks and wooden strips. This increases the connection points between the wooden strips and blocks, resulting in a more even distribution of force and improving the overall stability and load-bearing capacity of the wooden pallet.

[0026] 2. In this invention, the number of pneumatic nail guns installed can correspond to the number of pallets produced at one time, enabling the simultaneous binding and production of multiple pallets and improving work efficiency;

[0027] 3. This invention also provides the use of multi-nailing position formulas through the application of the debugging system, which can be switched at will to realize nailing at different nail positions. It can also adapt to nailing different combinations of wood strips and blocks by inputting the quantity and length of wood strips and blocks, ensuring the accuracy and stability of nailing and improving production efficiency.

[0028] 4. The present invention also provides a positioning component on the top of the sub-support to position the wooden blocks and wooden strips on all four sides before the sub-support moves, ensuring that the wooden blocks are all below the wooden strips and that the wooden strips are in a horizontal state, so as to avoid the displacement of the nailing position of the nail gun when it moves to the bottom of the nail gun, thus achieving precise nailing from multiple aspects.

[0029] 5. The present invention is also provided with a main drive cylinder and a rear drive cylinder. The main drive cylinder and the rear drive cylinder can first lift the completed tray to the point of being disengaged from the positioning position. Then the rear drive cylinder stops moving, and the main drive cylinder continues to lift, causing the rear side of the auxiliary support to gradually tilt. In this way, the tray can slide forward along the roller assembly, realizing the centralized collection of the tray, reducing manual operation costs and improving work efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Example 1

[0055] like Figures 1 to 17The pallet stacking machine shown includes a frame 1. A motor 2 is mounted on the left side of the frame 1, and rotating rods 3 are symmetrically arranged on the right side of the frame 1. A belt 4 connects the rotating rods 3 and the output shaft of the motor 2. A secondary support 5 is mounted on the top of the belt 4, and a positioning component 6 is mounted on the top of the secondary support 5. A gantry frame 7 is installed and connected between the front and rear of the middle of the frame 1. A first guide rail 8 is provided on the right side of the gantry frame 7, and a connecting support 10 is slidably mounted on the first guide rail 8. Multiple pneumatic nail guns 12 are slidably mounted on the right side of the connecting support 10 via multiple second guide rails 11. A first cylinder 13 is fixedly mounted on the left side of the gantry frame 7, and the output end of the first cylinder 13 is connected to the connecting support 10. The top of the support 10 is equipped with a second cylinder 14, the same number as the number of pneumatic nail guns 12. The output end of the second cylinder 14 is connected to the pneumatic nail gun 12. The positioning assembly 6 has multiple square plates 61, each with three flow grooves 62. A rear positioning plate 63 is provided on the square plate 61 behind the flow grooves 62. A flow rail 632 is provided at the bottom of the square plate 61 via multiple connecting brackets 631. Three front positioning plates 64 are slidably mounted on the flow rails 632. The front positioning plates 64 are respectively located in the flow grooves 62. A coupling 641 extends between the lower parts of the front positioning plates 64. A first push rod 642 is provided on the front side of the bottom of the square plate 61. The output end of the first push rod 642 is connected to the front... Positioning plates 64 are connected; there are 3 square plates 61, from left to right: a first square plate 65, a second square plate 66, and a third square plate 67. The first square plate 65 has a left side positioning plate 651 on its left side, the second square plate 66 has a middle side positioning plate 661 on its upper side, and the third square plate 67 has a right side positioning plate 671 slidably mounted on its top right side via a second push rod 672; the top inner sides of both the first square plate 65 and the third square plate 67 have 3 first push plates 68; the top inner sides of both the first square plate 65 and the third square plate 67 have 2 second push plates 69, the top of the second push plates 69 has a clamping block 691, and a horizontal plate 692 connects the clamping blocks 691. The top of the horizontal plate 692 has a... There are three plate positioning blocks 693; the bottom of the first square plate 65 and the third third plate 67 are provided with a main drive cylinder 15 and a rear drive cylinder 16 from back to front. The output rods of the main drive cylinder 15 and the rear drive cylinder 16 pass through the first square plate 65 and the third third plate 67, and are rotatably connected to the roller group 18 at the top through the hinge seat 17; the top front and rear sides of the frame 1 are provided with circular rails 19, and the front and rear sides of the auxiliary support 5 are symmetrically provided with rotating wheels 20, which slide in contact with the circular rails 19; multiple air tanks 21 are installed on the rear side of the frame 1, and the air tanks 21 provide air source for the first cylinder 13, the second cylinder 14, the first push rod 642, the second push rod 672, etc.

[0056] This invention utilizes a movable pneumatic nail gun 12 mounted on the gantry 7 to achieve multi-hole nailing between individual wooden blocks and strips, increasing the connection points between the strips and blocks, resulting in more even force distribution and improved overall stability and load-bearing capacity of the wooden pallet. Furthermore, the number of pneumatic nail guns 12 installed corresponds to the number of pallets produced at one time, enabling simultaneous assembly and production of multiple pallets, thus improving work efficiency. The invention also provides a multi-nailing position formula through the application of a debugging system, allowing for easy switching between different nailing positions. It also allows for high adaptability to nailing different combinations of strips and blocks by inputting the quantity and length of the wooden strips and blocks, ensuring accuracy and stability and improving production efficiency. Finally, the invention includes a positioning component 6 at the top of the sub-support 5. Before the secondary support 5 moves, the wooden blocks and strips are positioned on all four sides to ensure that the wooden blocks are all below the wooden strips and that the wooden strips are horizontal. This prevents the wooden blocks from shifting from the nailing position of the nail gun 12 when they move below the nail gun 12, thus achieving precise nailing from multiple angles. The invention also provides a main drive cylinder 15 and a rear drive cylinder 16 at the bottom of the first plate 65 and the third plate 67. The main drive cylinder 15 and the rear drive cylinder 16 can first lift the completed tray to release it from the positioning position. Then, the rear drive cylinder 16 stops moving, and the main drive cylinder 15 continues to lift, causing the rear side of the secondary support 5 to gradually tilt. In this way, the bracket can slide forward along the roller group 18, achieving centralized collection of the bracket, reducing manual operation costs and improving work efficiency.

[0057] Example 2

[0058] like Figures 1 to 12 The pallet stacking machine shown includes a frame 1. A motor 2 is mounted on the left side of the frame 1. The two output shafts of the motor 2 are symmetrically arranged front and back. When rotating rods 3 are symmetrically arranged front and back on the right side of the frame 1, the rotating rods 3 can be connected to the output shafts on the same side via belts 4. That is, two belts 4 are symmetrically arranged on the front and back sides of the frame 1. A secondary support 5 is installed between the top of the belts 4. When the motor 2 operates, it can drive the secondary support 5 to move via the belts 4. If wooden strips and wooden blocks are placed on the secondary support 5, the belts 4 can drive the wooden strips and wooden blocks on them to move, which can be used for nailing. It should be noted that, if Figure 15 In the "Debugging Screen" shown, the position of the belt 4 driven by motor 2 must be at the zero point before the machine starts working. You can check whether the current position of motor 2 is displayed as 0 in the main screen of the debugging interface. If it is 0, it means that motor 2 and belt 4 are in the correct position and you can start working directly. If it is not 0, click the "Reset" button in the debugging screen, and then click the "Return to Origin" button to trigger motor 2 to rotate and drive the auxiliary support 5 and above components to move automatically to the right through belt 4, returning to the zero point of motion, until the current position is displayed as 0 in the main screen.

[0059] In this embodiment, the nailing assembly is fixedly installed in the middle of the frame 1. A gantry frame 7 is installed and connected between the front and rear sides of the middle of the frame 1. Two first guide rails 8 are provided on the right side of the gantry frame 7. The first guide rails 8 are arranged symmetrically at the top and bottom. A connecting support 10 is slidably connected between the first guide rails 8. Multiple second guide rails 11 are provided on the right side of the connecting support 10. A number of pneumatic nail guns 12 are slidably mounted on the second guide rails 11. Correspondingly, multiple second cylinders 14 are provided on the top of the connecting support 10. The output end of the second cylinder 14 is connected to the top of the pneumatic nail gun 12. Thus, the operation of the second cylinder 14 can drive the pneumatic nail gun 12 to move downward and nail the wooden strips and blocks below. A first cylinder 13 is installed on the left side of the gantry frame 7. The output direction of the first cylinder 13 is forward, and the output shaft is connected to the connecting support 10. That is, the operation of the first cylinder 13 will drive the connecting support 10 and its pneumatic nail guns 12 to move back and forth.

[0060] Understandably, the number of trays that can be manufactured at one time in this invention corresponds to the number of pneumatic nail guns 12 and second cylinders 14 installed. When the number of pneumatic nail guns 12 is 1, the number of second guide rails 11 and second cylinders 14 is also 1; when the number of pneumatic nail guns 12 is 2, the number of second guide rails 11 and second cylinders 14 is also 2; when the number of pneumatic nail guns 12 is 3, the number of second guide rails 11 and second cylinders 14 is also 3, and so on.

[0061] It should be noted that, as Figure 13 The "Main Operation Screen" shown illustrates that the operation mode of all components of this product relies on the support of the debugging system. For easier understanding, this embodiment limits the number of trays that can be made at one time to 3, that is, the number of pneumatic nail guns 12 is also 3. The nailing debugging process of the tray is explained. In actual applications, it can be adjusted according to needs.

[0062] In this embodiment, the pallet is placed horizontally, meaning the wooden strips are placed horizontally on the secondary support 5. The number of nail blocks required for nailing is set from left to right at the bottom of the wooden strips. The two nail blocks on the left and right sides are tightly attached to the bottom left and right edges of the wooden strips, while the middle nail is evenly spaced according to the number of nail blocks. For example... Figure 14 In the "Parameter Setting Screen" shown, there are several, but not limited to, the following parameter variables during this debugging process: the extension time, nail ejection time, and displacement speed of the pneumatic nail gun 12. The nailing system supported by the above data generates three nailing formulas: a 2-nail formula, a 3-nail formula, and a 4-nail formula. Specifically, these represent the number of nails driven between each wooden block and wooden strip, and the fixed nailing positions. The nail positions on the wooden block are all located on the top surface in contact with the wooden strip. Specifically, as shown... Figure 16In the “Recipe Screen 1 / 2 / 3” shown, nail positions 2 are located at the two opposite corners of the wooden block, designated as a1 and a2; nail position 3 is located at the three points of the isosceles triangle formed by extending upwards from the bottom edge of the wooden block, designated as b1, b2, and b3; nail position 4 is located at the four corners of the wooden block, designated as c1, c2, c3, and c4.

[0063] It should be noted that the nailing and debugging system used in this application can support nailing operations for up to 6 piers, and the pier spacing α is calculated using the formula "pier spacing α = (timber strip length - pier width) ÷ (number of piers - 1)".

[0064] For ease of understanding, this embodiment limits the number of wooden blocks to 3, thus providing 3 block positions for the wooden strips. Two identical block spacing α are created between these 3 block positions. After placing the wooden strips and 3 blocks, the worker can manually input the length of the wooden strips and the width of the blocks to calculate the block spacing α. Then, a nailing formula is selected, specifying the positions of at least 2 nails. This can be understood as follows: the value of nail position 1 is the distance between a1, b1, and c1 and the left edge of the block position; the value of nail position 2 is the horizontal distance between (a2-a1), (b2-b1), and (c2-c1), and so on. That is, in a 2-nailing-position formula, inputting the positions of at least 2 nails directly determines the nail positions; in a 3-nailing-position formula, the positions of all 3 nails can be directly input, or the 3rd nail position can be calculated after inputting the positions of the 2nd nail; in a 4-nailing-position formula, the positions of all 4 nails can be directly input, or the 4th nail position can be automatically calculated after inputting the positions of the 3rd nail.

[0065] The overall debugging process is as follows: First, debug the parameters of the main operation page. Then, enter the recipe screen and place the specified number of wooden blocks (9) and wooden strips (3) in the recipe screen. Input the length of the wooden strips as 1200, the number of wooden blocks as 3, and the width as 90. The system calculates the block spacing α = (wooden strip length - wooden block width) ÷ (number of wooden blocks - 1) = (1200 - 90) ÷ 2 = 555. After confirming that the data and the actual measured data of the wooden blocks are correct, select the required nailing recipe: 2-nailing position recipe, 3-nailing position recipe, or 4-nailing position recipe. Press the "Recipe Confirmation" button and return to the main screen. Press the "Automatic Nailing" and "Nail Dispensing" buttons, and the machine will start making the pallet.

[0066] It should be noted that the procedure for each nail position of the pneumatic nail gun 12 is as follows:

[0067] For the 2-nailing position formula, the wooden strip and block move to the left until point a1 is below the pneumatic nail gun 12, then pause. The second cylinder 14 operates, causing the pneumatic nail gun 12 to move downward and drive the first nail at point a1. The second cylinder 14 then moves the pneumatic nail gun 12 upward to reset. Subsequently, the first cylinder 13 moves the entire connecting support 10 backward by a specified nail distance. At the same time, the wooden strip and block continue to move to the left until point a2 is below the pneumatic nail gun 12, then pause. The second cylinder 14 operates, causing the pneumatic nail gun 12 to move downward and drive the second nail at point a2. Subsequently, both the first cylinder 13 and the second cylinder 14 reset, causing the pneumatic nail gun 12 to move upward and forward to reset, completing one 2-nailing position nailing action. This is repeated 3 times to finish nailing and obtain the tray.

[0068] For the 3-nailing method, the wooden strip and block move to the left until point b1 is below the nail gun 12, then pause. The second cylinder 14 operates, causing the nail gun 12 to move downwards and drive the first nail at point b1. The nail gun 12 then moves upwards to reset. Subsequently, the first cylinder 13 drives the nail gun 12 backwards by a specified nail distance. At the same time, the wooden strip and block continue to move to the left until point b2 is below the nail gun 12, then pause. The second cylinder 14 drives the nail gun 12 downwards and drives the second nail at point b2. The nail gun 12 then resets. Subsequently, the first cylinder 13 drives the nail gun 12 forward by a specified nail distance. The wooden strip and block continue to move to the left until point b3 is below the nail gun 12, then pause. The nail gun 12 moves downwards and drives the third nail at point b3. Finally, the second cylinder 14 drives the nail gun 12 upwards to reset, completing one 3-nailing action. This process is repeated 3 times to finish nailing and obtain the tray.

[0069] For the 4-nailing configuration, the wooden strip and block move to the left until point c1 is below the nail gun 12, then pause. The second cylinder 14 operates, causing the nail gun 12 to move downwards and drive the first nail at point c1. The nail gun 12 then moves upwards to reset. The wooden strip and block continue to move to the left until point c2 is below the nail gun 12, then pause. The second cylinder 14 drives the nail gun 12 downwards and drives the second nail at point c2. The nail gun 12 then moves upwards to reset. Subsequently, the first cylinder 13 drives the nail gun 12 backwards at a specified nail distance until point c3 is below the nail gun 12, where the nail gun 12 drives the third nail. Then, the wooden strip and block move to the right until point c4 is below the nail gun 12, where the nail gun 12 drives the fourth nail. Then, both the first cylinder 13 and the second cylinder 14 reset, causing the nail gun 12 to move upwards and forwards to reset, completing one 4-nailing cycle. This process is repeated 3 times to finish nailing and obtain the tray.

[0070] Example 3

[0071] like Figures 1 to 12The pallet stacking machine shown also includes a positioning component 6 set on the top of the sub-support 5, which can realize the alignment between the wooden blocks and the wooden strips, ensuring accurate nailing and the quality of the finished pallets.

[0072] The number of pallets required for one-time production is limited to 3, thus the number of square plates 61 in the positioning component 6 is set to 3. Each square plate 61 has 3 flow grooves 62, which are vertically opened from front to back. A front positioning plate 64 is slidably installed in the flow groove 62, i.e., 3 front positioning plates 64. A coupling 641 extends between the lower parts of the front positioning plates 64, i.e., the coupling 641 can connect the movement of the 3 front positioning plates 64 together. Then, when a first push rod 642 is set on the front side of the bottom of the square plate 61, the output direction of the first push rod 642 is backward, and the output end of the first push rod 642 is connected to a certain front positioning plate 64, When the first push rod 642 is driven, the designated front positioning plate 64 can be moved, and then the three front positioning plates 64 can be moved synchronously through the coupling 641. At the same time, a rear positioning plate 63 is provided on the square plate 61 at the rear side of the flow channel 62, that is, three rear positioning plates 63. The rear positioning plates 63 are fixedly set, and the front side of the rear positioning plate 63 and the corresponding front positioning plate 64 form a placement space for placing wooden blocks. In this way, the staff manually places the wooden blocks between the rear positioning plates 63 and the front positioning plates 64 respectively, and the first push rod 642 performs a telescopic action to push the wooden blocks to the front side of the rear positioning plate 63.

[0073] The square plate 61 can be further divided into three parts: a first square plate 65 and a third square plate 67 arranged symmetrically on the left and right, and a second square plate 66 located between them. The first square plate 65 has a left side positioning plate 651 on its left side, the third square plate 67 has a right side positioning plate 671 on its top right side, and the second square plate 66 has a middle side positioning plate 661. When all the above positioning plates are fixed, they can cooperate with the rear positioning plate 63 to form a fixed angle position, so that the workers can use this angle space as a reference to place the wooden block. Then, the first push rod 642 drives the front positioning plate 64 to perform a telescopic movement to position the wooden block on three sides. Furthermore, there are three first push plates 68 on the top inner side of the first square plate 65 and the third square plate 67. The output direction of the first push plates 68 is towards the positioning plate on the square plate. Then, the first push plates 68 and the first push rod 642 are driven synchronously to achieve four-sided positioning of the wooden block.

[0074] Example 4

[0075] Understandably, when the left side positioning plate 651 is fixed in position, allowing the right side positioning plate 671 to slide, and a second push rod 672 is installed on the top right side of the third side plate 67 to drive the right side positioning plate 671, the left and right positioning of the wooden strips can be achieved simultaneously. Simultaneously, when the left and right ends of the wooden strips are also placed against the rear positioning plate 63, the rear positioning of the wooden strips can also be achieved simultaneously. That is, when the worker places the left and right ends of the three wooden strips against the rear positioning plate 63, and then the second push rod 672 performs a retraction action to push the right side positioning plate 671 to position the three wooden blocks on the right, the left and right positioning of the wooden strips can also be completed simultaneously. Furthermore, the following components are provided for the front positioning of the wooden strips:

[0076] Two second push plates 69 are provided on the inner top of the first square plate 65 and the third square plate 67. The second push plates 69 are staggered with the first push plates 68, and the output direction of the second push plates 69 on the same plate is the same, facing backward. The output end of the second push plate 69 is provided with a clamping block 691, and the clamping block 691 is slidably disposed on the top of the second push plate 69. That is, the operation of the second push plate 69 can push the clamping block 691 to move back and forth on the second push plate 69. A horizontal plate 692 is connected between the clamping blocks 691. The top of the horizontal plate 692 is provided with three board positioning blocks 693 for positioning the front side of the wood strip.

[0077] The positioning process for the wooden blocks and strips is as follows: Workers manually place nine wooden blocks between the front positioning plate 64, the rear positioning plate 63, and each side positioning plate. Then, three wooden strips are placed horizontally between the left side positioning plate 651 and the right side positioning plate 671, with the front and rear sides of the strips positioned between the board positioning block 693 and the front positioning plate 64. Immediately, the first push rod 642, the second push rod 672, the first push plate 68, and the second push plate 69 simultaneously extend and retract, achieving four-sided positioning of the wooden blocks and strips. This ensures that the wooden blocks are all below the strips and that the strips are horizontal, preventing them from shifting from the nailing position of the nail gun 12 when they move below it, thus achieving precise nailing from multiple angles.

[0078] Example 5

[0079] like Figures 1 to 12The pallet stacking machine shown has its parameters pre-adjusted. After starting operation, the positioning component 6 on the auxiliary support 5 positions the wooden blocks and strips placed on it. Then, the motor 2 drives the belt 4 to rotate, which in turn moves the auxiliary support 5 to the left. When the wooden block moves below the pneumatic nail gun 12, the motor 2 stops, and the pneumatic nail gun 12 nails the wooden strips and blocks below. After nailing, the motor 2 starts again, and the pneumatic nail gun 12 makes the corresponding displacement according to the nail position until nailing is finished. Then, the motor 2 reverses and drives the belt 4 and the finished pallet to move to the right to reset. Then, the motor 2 stops operating, and the pallet is ready to be unloaded.

[0080] To achieve automatic pallet unloading, this embodiment also includes a main drive cylinder 15 and a rear drive cylinder 16 at the bottom of the first square plate 65 and the third square plate 67. The main drive cylinder 15 is located at the rear, and the rear drive cylinder 16 is located at the front. The output rods of both the main drive cylinder 15 and the rear drive cylinder 16 pass through the first square plate 65 and the third square plate 67, and are rotatably connected to a roller assembly 18 on the top support via a hinge seat 17. The roller assembly 18 is specifically a housing with multiple rollers rotatably mounted, and the rollers protrude from the top. At the highest point of the shell, and with the roller assembly 18 still below the wooden strips; that is, the nailed pallet is still set horizontally. At this time, the main drive cylinder 15 and the rear drive cylinder 16 move upward together, lifting the pallet upward until it is no longer restricted by the wooden block. Then the rear drive cylinder 16 stops moving, and the main drive cylinder 15 continues to lift, causing the rear side of the sub-support 5 to gradually tilt. In this way, the bracket can slide forward along the roller assembly 18. By simply placing a collection box in front of the sub-support 5, the bracket can be collected in a concentrated manner.

[0081] Example 6

[0082] Understandably, belts 4 in existing knowledge all have a certain degree of toughness. Belts 4 with sub-supports 5 and wooden brackets inevitably tend to sag downwards. Therefore, symmetrical rollers 20 are also provided on both the front and rear sides of the sub-support 5. Correspondingly, circular rails 19, which are cylindrical slide rails, are provided on the front and rear sides of the top of the frame 1. In this way, the recessed rollers 20 can contact and slide with the circular rails 19, cooperating with the sub-support 5 to move left and right on the same horizontal line. This not only enables nailing but also provides support for the sub-support 5 during left and right movement, ensuring its horizontal left and right movement.

[0083] Furthermore, multiple air tanks 21 are installed on the rear side of the frame 1. These air tanks 21 provide air supply for various pneumatic components. Specifically, in this application, the first cylinder 13 drives the connecting support 10, the second cylinder 14 drives the pneumatic nail gun 12, the first push rod 642 drives the front positioning plate 64, the second push rod 672 drives the right side positioning plate 671, the first push plate 68 pushes the wooden block, the second push plate 69 drives the plate positioning block 693, the main drive cylinder 15, and the rear drive cylinder 16. It should be noted that the normal working air pressure range of this application is 0.7 MPa-0.8 MPa. Before the machine operates, it is necessary to check whether the air lines are tightly connected and leak-free, and then confirm whether the machine's working air pressure is normal, ensuring that the internal air system of the equipment is unobstructed. Then, enter the debugging screen and manually press the start button of each pneumatic component to start each pneumatic component and check whether the relevant pneumatic components are in normal working condition, ensuring the safe and efficient operation of the pneumatic jacking machine.

[0084] Example 7

[0085] In summary, as Figures 1 to 17 As shown, this embodiment relates to a control method for a pallet stacking machine and a pallet manufacturing process, as detailed below:

[0086] S01: Place the wooden blocks between the front positioning plate 64, the rear positioning plate 63 and each side positioning plate;

[0087] S02: Place the wooden strip between the board positioning block 693, the front positioning plate 64, the left side positioning plate 651 and the right side positioning plate 671;

[0088] S03: Connect the power to start the jacking machine, open the human-machine interface (HMI), check the working air pressure of the machine to see if it is between 0.7Mpa and 0.8Mpa, then enter the "debugging screen" to check if each pneumatic component is in normal operating condition.

[0089] S05: Return to the main page to check if motor 2 is at the zero point, that is, whether the current position is displayed as 0. If not, first click the "Reset" button, then click the "Return to Origin" button. Motor 2 will automatically find the operating zero point until the current position is displayed as 0.

[0090] S06: After inspecting the above components, adjust and input the parameters in the "Parameter Setting" screen, and select the required nail position formula;

[0091] S07: Motor 2 drives the wooden block and wooden strip to move to the left. At the same time, the pneumatic nail gun nails the wooden block according to the nail position formula until all the wooden block points are nailed, and a tray is obtained.

[0092] S08: Motor 2 reverses its operation, driving the auxiliary support 5 and the tray to move to the right and return to the origin of motion until it stops moving;

[0093] S09: The system detects that motor 2 has stopped operating, and starts the main drive cylinder 15 and the rear drive cylinder 16 to lift upward, so that the roller assembly 18 is in a forward tilted state;

[0094] S10: The tray falls forward along the roller assembly 18, completing the collection, and the main drive cylinder 15 and the rear drive cylinder 16 are reset.

[0095] Specifically, such as Figure 17 As shown, during this period, safety warnings issued due to missing nails, component failures, abnormal parameters, etc., will be recorded on the alarm screen. The alarm screen is usually arranged with the most recent alarm at the top, but it can also be searched by date for subsequent analysis and tracking. In addition, a quick nail replacement screen is set up according to the missing nail phenomenon. The screen will display the total number of nails that can be stored in each nail gun (1500), the number of remaining nails, the actual number of nails, and the current number of nails. The staff can operate to replenish the nails.
