Description

Technical Field

[0001] This invention relates to the field of production automation, and in particular to an independent lifting cylinderless intermediate narrow rail plate buffer machine. Background Technology

[0002] In existing sheet metal processing or transfer processes, to ensure production continuity, buffer mechanisms are often installed between equipment for temporary storage and orderly transport of sheet metal. Traditional buffer machines mostly use cylinders as lifting actuators, adjusting the height of the buffer frame by moving the cylinder. However, cylinder structures suffer from problems such as large size, limited stroke, and unstable response speed. Furthermore, cylinders rely heavily on compressed air systems, resulting in high energy consumption and maintenance costs. In addition, existing buffer machines lack adaptability to sheet metal specifications, typically only capable of storing and transporting sheets of fixed sizes. When the length or width of the sheet metal changes, the distance between the buffer frame and the buffer plate cannot be flexibly adjusted, leading to poor compatibility with sheets of different sizes.

[0003] In terms of conveying control, traditional buffer mechanisms often rely on a single conveyor belt to complete the feeding and discharging actions. When the buffer frame changes height, the conveyor drive system struggles to maintain synchronization with the buffer plate, easily leading to conveying position deviations or jamming, affecting the stable feeding and discharging of the sheet metal. Furthermore, to ensure the overall structural stability of the buffer machine, some components occupy a significant amount of space, limiting its application in narrow-gauge conditions and reducing buffering efficiency and equipment integration. Therefore, how to achieve independent height adjustment of the buffer machine without cylinders, flexibly adjust the buffer spacing according to the sheet metal size, and ensure that the conveyor belt continues to stably drive the sheet metal feeding and discharging during height changes is a problem that current technology urgently needs to solve. Meanwhile, the current board material buffer machines often have large gaps between adjacent boards, requiring pre-alignment operations when the board is picked up and processed by the pick-and-place machine. This increases the number of process steps required by traditional equipment and is not conducive to improving efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of the existing structural drawbacks of sheet metal buffer equipment, and to propose an independent lifting cylinderless narrow-rail sheet metal buffer machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an independent lifting cylinderless intermediate narrow rail plate material buffer machine, comprising a cabinet with symmetrical material inlets in the middle, two buffer machines for material storage installed on both sides of the inner wall of the cabinet, and a lifting component for controlling the height of the buffer machines installed inside. The buffer machine includes a buffer frame with an inner wall spacing that is adapted to the length of the sheet material, and two buffer plates symmetrically installed inside the buffer frame. Each buffer plate includes a plate body installed on the inner wall of the buffer frame, and several conveyor belts are rotatably arranged on the plate body. A conveying component for driving the corresponding conveyor belts at a fixed height is installed on the plate body.

[0006] As a further description of the above technical solution: the lifting assembly includes two vertical slide rods fixed to the inner wall of the cabinet, and a lifting screw that is threadedly engaged with the buffer rack is provided between the two vertical slide rods. A reducer that drives the lifting screw is provided at the top of the lifting screw, and a lifting motor is installed at the input end of the reducer.

[0007] As a further description of the above technical solution: the buffer rack includes a main frame for mounting two buffer plates, and each of the four corners of the main frame is rotatably connected with an adjusting screw threaded through the plate, and the four adjusting screws engage with an adjusting chain for transmission, and an adjusting motor for driving the adjusting chain is installed on the top of the main frame.

[0008] As a further description of the above technical solution: the inner wall of the main frame is fixed with two horizontal sliding rods for sliding the plate, and one side of the main frame is fixed with a sliding seat for sliding in conjunction with the vertical sliding rod.

[0009] As a further description of the above technical solution: the fixed-point transmission device includes a guide rail fixed to one side of the plate and a fixed seat that slides on the guide rail. A buffer rail is fixed to one side of the fixed seat, a wheel frame slides on the buffer rail, and a transmission gear set is rotatably mounted on the wheel frame.

[0010] As a further description of the above technical solution: the conveying assembly also includes a conveying motor fixed to the top of the plate, the output end of the conveying motor drives a transmission chain meshing with one side of the plate, and the transmission chain meshes with a transmission gear set.

[0011] As a further description of the above technical solution: the bottom of the fixed seat is fixed with a fixed shaft, the bottom end of the fixed shaft is fixedly connected to the inner wall of the cabinet, and the bottom end of the plate interacts with the fixed shaft.

[0012] As a further description of the above technical solution: two limiting grooves are opened on one side of the fixed seat, and springs are installed on the inner wall of the limiting grooves. The columnar protrusions on the wheel frame slide in the limiting grooves and press the springs.

[0013] As a further description of the above technical solution: a pulley is fixed at the end of the conveyor belt, and the pulley meshes with a transmission gear set.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: This solution allows for independent height adjustment of the buffer unit, which is controlled separately by two lifting components. Meanwhile, the buffer machine, driven by the coordinated operation of the regulating motor and the regulating chain, causes the regulating screws at its four corners to move the two buffer plates closer or further apart on the horizontal slide bar, thereby adjusting the spacing to accommodate the storage of materials of different sizes. The solution uses a fixed-axis support to maintain a constant height within the cabinet. When the height of the buffer rack and the two buffer plates changes, the conveyor motor and transmission chain move simultaneously with the plates, causing the transmission gear set to rotate along with the movement of the transmission chain. The pulley meshing with it moves simultaneously but does not rotate, thus enabling the entire system to control the feeding and discharging of the corresponding conveyor belt plates at the height of the material in the material inlet by the transmission gear set during the height changes of the buffer rack and the buffer plates. Meanwhile, the above-mentioned structural integration of this solution achieves a cylinder-free design for both buffer machines and adopts a narrow rail design with extremely small spacing, which greatly improves the efficiency of material plate buffering. This solution employs a narrow rail design, which minimizes the spacing between adjacent material boards, meeting the alignment requirements of SPI or pick-and-place machines. This eliminates the need for additional translation equipment during pick-and-place machine material handling, allowing for direct alignment and significantly improving process efficiency.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0018] like Figure 1 - Figure 9 As shown, the present invention provides: an independent lifting cylinderless intermediate narrow rail plate material buffer machine 30, including a cabinet 10 with symmetrical material inlets 40 in the middle, two buffer machines 30 for material storage installed on both sides of the inner wall of the cabinet 10, and a lifting component 20 for controlling the height of the buffer machines 30 installed inside. The buffer machine 30 includes a buffer frame 31 whose inner wall spacing is adapted to the length of the sheet material, and two buffer plates 32 symmetrically installed inside the buffer frame 31. Each buffer plate 32 includes a plate body 321 installed on the inner wall of the buffer frame 31, and a plurality of conveyor belts 323 are rotatably arranged on the plate body 321. A conveying assembly 322 for driving the corresponding conveyor belts 323 at a fixed height is installed on the plate body 321.

[0019] By setting up independent lifting components 20 within the cabinet 10, the two buffer machines 30 can be height-adjusted independently, thereby achieving layered independent control during the caching and conveying of sheet metal, improving the flexibility of storage and transmission. The buffer machine 30 uses regulating screws 314 arranged at the four corners of the main frame 311, and driven by the regulating motor 312 and the regulating chain 313, the two buffer plates 32 can move closer or further apart on the horizontal slide bar 315, thereby automatically adjusting the spacing according to different sizes of sheet metal, ensuring the device's adaptability to multiple specifications of sheet metal, and solving the limitation of traditional devices that can only be used for single-size sheet metal.

[0020] In terms of conveying control, this solution maintains the stability of the buffer frame 31 during the lifting process by supporting the fixed seat 02 structure with the fixed shaft 03. When the conveying motor 3221 drives the transmission chain 3222, the transmission gear set 06 can maintain meshing with the pulley 3224 as the height of the buffer plate 32 changes, so that the conveyor belt 323 can achieve stable feeding and discharging control at any height, avoiding the problem of asynchronous conveying or jamming caused by height changes in the prior art.

[0021] Furthermore, the fixed-point transmission device 3223, through the cooperation of the guide rail 01, the buffer rail 04, and the wheel frame 05, ensures that the transmission gear set 06 maintains stable operation during force and displacement, further improving the reliability of the conveying process. This solution adopts a cylinderless structure, avoiding reliance on a compressed air system, reducing energy consumption and maintenance costs. Simultaneously, its narrow-rail design effectively reduces the space occupied by the device, improving the compactness and buffering efficiency of the buffer machine 30, thus providing significant advantages in the continuity and stability of sheet metal processing and conveying.

[0022] Specifically, such as Figure 4 As shown, the lifting assembly 20 includes two vertical slide rods 24 fixed to the inner wall of the cabinet 10. A lifting screw 23 that is threadedly engaged with the buffer rack 31 is provided between the two vertical slide rods 24. A reducer 22 that drives the lifting screw 23 is provided at the top of the screw, and a lifting motor 21 is installed at the input end of the reducer 22.

[0023] The lifting assembly 20 includes two vertical slide rods 24 fixed to the inner wall of the cabinet 10, which provide linear guidance and support for the up-and-down movement of the buffer rack 31, ensuring that it does not deviate or sway during the lifting process, thereby improving the overall stability and accuracy of operation. A lifting screw 23, threadedly engaged with the buffer rack 31, is provided between the two vertical slide rods 24. Utilizing the transmission characteristics of the threaded pair, the rotational motion of the motor is converted into the linear lifting motion of the buffer rack 31, achieving precise control of the height of the buffer plate 32. A reducer 22 is provided at the top of the lifting screw 23. The reducer 22 reduces the motor speed and amplifies the torque, making the lifting process smoother and capable of bearing a larger load, avoiding impacts and vibrations caused by rapid rotation. A lifting motor 21 is installed at the input end of the reducer 22. The lifting motor 21 serves as the power source for the entire lifting assembly 20, enabling flexible adjustment of the buffer rack 31 under the drive of the electronic control system. Through the combination of motor, reducer 22, lifting screw 23 and vertical slide bar 24, the lifting assembly 20 not only achieves precise adjustment of the height of the buffer rack 31, but also ensures the synchronization and stability of the entire lifting process, so that the buffer machine 30 has high reliability and control precision when adapting to different height and position requirements.

[0024] Specifically, such as Figure 6 As shown, the buffer rack 31 includes a main frame 311 for mounting two buffer plates 32. Each of the four corners of the main frame 311 is rotatably connected to an adjusting screw 314 threaded through the plate 321, and the four adjusting screws 314 engage with an adjusting chain 313 for transmission. A adjusting motor 312 for driving the adjusting chain 313 is mounted on the top of the main frame 311.

[0025] The buffer rack 31 includes a main frame 311 for mounting two buffer plates 32. As the core load-bearing structure of the buffer machine 30, the main frame 311 not only provides a stable mounting position for the buffer plates 32 but also supports the overall force and transmission, ensuring the buffer machine 30 maintains structural strength and stability during long-term operation. Each of the four corners of the main frame 311 is rotatably connected to an adjusting screw 314 threaded through the plate 321. The adjusting screws 314, through the action of the threaded joint, enable relative sliding of the plate 321 on the main frame 311, thereby driving the two buffer plates 32 to adjust their horizontal position, avoiding mismatch issues caused by changes in plate size. The four adjusting screws 314 are engaged with an adjusting chain 313. The adjusting chain 313 ensures that the four adjusting screws 314 rotate synchronously, guaranteeing uniform force on the four corners of the buffer plates 32 during adjustment. This prevents tilting or jamming of the plate 321 due to uneven force on one side, further improving the smoothness and reliability of the adjustment action. The top of the main frame 311 is equipped with a control motor 312 for driving the control chain 313. The control motor 312, as a power source, can precisely drive the chain under the control system, achieving automated adjustment of the spacing between the buffer plates 32. Through the cooperation of the control motor 312, the control chain 313, and the control screw 314, the buffer rack 31 can quickly and stably adapt to the storage needs of plates of different specifications, thereby improving the adaptability and overall operating efficiency of the buffer machine 30 under multiple working conditions.

[0026] The inner wall of the main frame 311 is fixed with two horizontal slide rods 315 for sliding the plate 321, and a slide block 316 for sliding with the vertical slide rod 24 is fixed on one side of the main frame 311.

[0027] The horizontal slide bar 315 serves as a guide, maintaining the stability of the displacement of the buffer plate 32.

[0028] Specifically, such as Figure 8 and Figure 9 As shown, the fixed-point transmission device 3223 includes a guide rail 01 fixed to one side of the plate 321, and a fixed seat 02 that slides on the guide rail 01. A buffer rail 04 is fixed to one side of the fixed seat 02, and a wheel frame 05 slides on the buffer rail 04. A transmission gear set 06 is rotatably mounted on the wheel frame 05.

[0029] The fixed-point transmission device 3223 includes a guide rail 01 fixed to one side of the plate 321. The guide rail 01 provides precise constraint and guidance for the lifting and lowering process of the plate 321, ensuring the smooth relative movement of the fixed-point transmission device 3223 with the plate 321 and avoiding poor engagement due to misalignment. The fixed seat 02 sliding on the guide rail 01 plays a role in bearing and positioning during operation, enabling it to maintain a constant trajectory as the height of the plate 321 changes, thereby ensuring that the entire transmission system can maintain normal operation at different heights.

[0030] A buffer slide rail 04 is fixed to one side of the fixed seat 02. The buffer slide rail 04 can absorb and disperse part of the impact force during the transmission of the fixed seat 02, improving the overall smoothness and durability of the operation and reducing vibration and noise during gear transmission. A wheel frame 05 slides on the buffer slide rail 04. The wheel frame 05 serves as a load-bearing component of the transmission gear set 06 and can achieve smooth reciprocating movement under the constraint of the buffer slide rail 04, maintaining a stable meshing state between the gear set and the transmission chain 3222. The transmission gear set 06 is rotatably mounted on the wheel frame 05. The transmission gear set 06 achieves efficient power transmission from the conveyor motor 3221 to the conveyor belt 323 through meshing with the transmission chain 3222 and pulley 3224, ensuring smooth conveying of the sheet material at the inlet and outlet. The overall structural design enables the fixed-point drive 3223 to maintain effective linkage of the transmission system during the lifting and lowering of the buffer frame 31, ensuring the continuous working capacity of the conveyor belt 323 under height changes and improving the reliability and stability of the device during long-term operation.

[0031] The conveying assembly 322 also includes a conveying motor 3221 fixed to the top of the plate 321. The output end of the conveying motor 3221 drives a transmission chain 3222 meshing with one side of the plate 321, and the transmission chain 3222 meshes with the transmission gear set 06.

[0032] As the core power source of the entire conveying system, the conveyor motor 3221 can achieve efficient and stable output under the action of control signals. Its position at the top of the plate 321 facilitates a close transmission relationship with the drive chain 3222, while avoiding occupying internal space of the buffer 30, thus improving the structural compactness of the device. The output end of the conveyor motor 3221 drives the drive chain 3222 meshing with it on one side of the plate 321. Driven by the motor, the drive chain 3222 achieves continuous cyclic transmission. Its chain links maintain good meshing with the transmission gear set 06, ensuring strong reliability and anti-slip properties during power transmission. The meshing of the drive chain 3222 and the transmission gear set 06 achieves synchronous drive of the conveyor belt 323, enabling precise control of the feeding and discharging actions of the plate material on the buffer plate 32. This structure not only ensures the high efficiency and stability of power transmission, but also maintains the stable meshing of the chain and gears when the height of the buffer frame 31 changes, thereby enabling the continuous operation of the conveyor belt 323 at different heights. This avoids transmission interruption or asynchrony caused by height changes, and significantly improves the overall working reliability and conveying efficiency of the buffer machine 30.

[0033] The bottom of the fixed seat 02 is fixed with a fixed shaft 03, the bottom end of the fixed shaft 03 is fixedly connected to the inner wall of the cabinet 10, and the bottom end of the plate 321 interacts with the fixed shaft 03.

[0034] The fixed shaft 03 supports and fixes the fixed seat 02, so that when the plate 321 moves, the height of the fixed seat 02 will not change. At the same time, the chain moves accordingly and can drive the transmission gear set 06 to rotate, thereby preventing the conveyor belt 323 from rotating.

[0035] Two limiting grooves 07 are provided on one side of the fixed seat 02, and springs 08 are installed on the inner wall of the limiting grooves 07. The columnar protrusions on the wheel frame 05 slide in the limiting grooves 07 and press the springs 08.

[0036] Spring 08 provides an elastic pressure to wheel frame 05 in limiting groove 07, so that wheel frame 05 elastically presses transmission gear set 06 onto pulley 3224 to maintain engagement.

[0037] The end of the conveyor belt 323 is fixed with a pulley 3224, which meshes with the transmission gear set 06.

[0038] In use, the lifting motor 21 drives the lifting screw 23 to rotate, causing the main frame 311 to change height under the threaded engagement until the corresponding conveyor belt 323 of the buffer plate 32 moves to the corresponding height of the material inlet 40. Then, the conveyor motor 3221 drives the fixed-point transmission device 3223 through the transmission chain 3222 to rotate the conveyor belt 323 at that height. With the cooperation of the two buffer plates 32, the conveyor belt 323 realizes the input and output control of the plate material.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
