Description

Technical Field

[0001] The present invention relates to the technical field of thin plate conveying, and particularly to a conveying device and method based on the processing of high-strength non-ferrous metal aluminum plates. Background Art

[0002] The precision conveyor in an automated stereoscopic warehouse is one of the core devices of the warehouse automation system, mainly used for the efficient, accurate transportation and storage of goods. It quickly transfers goods between different areas of the warehouse (such as the receiving area, the warehousing area, and the shipping area) through different forms such as roller tracks, chains, belts, or lifting mechanisms, and cooperates with the stacker to complete the automatic storage and retrieval of goods. Its precision is reflected in high-precision positioning, stable transmission, and seamless integration with the control system to ensure that there are no deviations or damages to the goods during the conveying process; For example, a metal plate positioning and conveying device disclosed in the prior art patent with the publication number CN221458863U includes a support frame. A rotating shaft is arranged in the middle of the support frame, and transmission belts are arranged on both sides of the rotating shaft. A rotating motor is installed on the right side of the transmission belt. A conveyor belt is arranged on the outer surface of the rotating shaft. An anti-slip component is arranged in the middle of the conveyor belt. Clamping components are installed on both sides of the conveyor belt. The clamping component includes a clamp, anti-slip teeth, a bottom frame, fixing screws, and a magnet. Clamps are installed on both sides of the conveyor belt, and anti-slip teeth are arranged on the inner and outer surfaces of the clamps. The metal plate is positioned and conveyed through the clamping component. The clamping component is made of rubber strip material with moderate hardness, which is convenient for the conveyor belt to bend and wind. The clamping component conveys the metal plate to the outlet of the conveyor belt. The clamping component rotates along with the conveyor belt during turning, so that the metal plate in the middle of the clamping component can fall into the storage box for storage; In the precision conveying scenario of an automated stereoscopic warehouse, due to the light weight of the thin plate, especially the density of aluminum is lower than that of iron. The density of iron is 7.8 g / cm³, and the density of aluminum is 2.7 g / cm³. Therefore, during the conveying process of the aluminum plate, the aluminum plate may deviate from the conveyor belt, resulting in deviation in the transfer area, and then causing deviation during the subsequent palletizing process in the automated stereoscopic warehouse, resulting in uneven palletizing. The prior art generally uses the method of baffle to solve this problem, but after setting the baffle, the blocked area is not convenient for personnel to observe and subsequent other mechanical equipment to pick it up. Summary of the Invention

[0003] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and title of the specification of this application, to avoid obscuring the purpose of this part, the abstract, and the title. However, such simplifications or omissions cannot be used to limit the scope of the present invention.

[0004] The present invention provides a conveying device and method for processing high-strength non-ferrous metal aluminum plates, which can solve the problem of metal aluminum plates deviating from the conveyor belt. The specific solution is as follows: On the one hand, the present invention provides a conveying device for processing high-strength non-ferrous metal aluminum plates, including a conveyor belt and conveying rollers. The conveyor belt moves under the drive of the conveying rollers. A number of negative pressure holes are provided in the conveyor belt. The outside of the conveyor belt is used to carry metal aluminum plates. At least a part of the conveyor belt has a vertical bending part. An aligning roller that rotates in the same direction as the conveying roller is provided on the outer wall of the vertical bending part. The aligning roller is located outside the conveyor belt. An adsorption device is installed on the inner surface of the conveyor belt, and the adsorption device forms positive pressure and negative pressure; Among them, the adsorption device forms a negative pressure channel and is connected to the negative pressure holes on the conveyor belt. The adsorption device forms a positive pressure channel and is connected to the inner cavity of the aligning roller; The outer end of the negative pressure hole abuts against the metal aluminum plate, so that negative pressure is formed in the negative pressure hole to adsorb the metal aluminum plate.

[0005] Preferably, the conveyor belt sequentially forms a continuous conveying part, a vertical transmission part, a horizontal transmission part, and a vertical bending part in a counterclockwise order. The vertical bending part is divided into a vertical bending part and a horizontal bending part.

[0006] Preferably, the aligning roller is provided with a double-direction spiral groove, and a number of air blowing holes are provided in the groove of the double-direction spiral groove. The air blowing holes are communicated with the inner cavity of the aligning roller.

[0007] Preferably, a capillary adsorption cotton is connected to the aligning roller. The capillary adsorption cotton is arranged in a double-direction symmetric spiral on the aligning roller. The capillary adsorption cotton arranged in a double-direction spiral converges in the middle of the aligning roller. The capillary adsorption cotton is coated with an adsorption liquid.

[0008] Preferably, an adsorption liquid storage tank is provided below the aligning roller. An elastic liquid guide block is provided in the storage tank. The liquid guide block is made of cotton fiber material. The elastic liquid guide block is connected to the bottom of the inner wall of the storage tank through a spring.

[0009] Preferably, the adsorption device includes: A negative pressure pump; A negative pressure cylinder, installed on the inner surface of the conveyor belt, with a number of through holes provided around it. One end of the negative pressure cylinder is connected to the negative pressure end of the negative pressure pump; A backing plate, provided between the negative pressure cylinder and the conveyor belt. A communication hole is provided in the middle of the backing plate; A fixing frame. Both ends of the negative pressure cylinder, the backing plate, the conveying roller, and the aligning roller are rotatably connected to the fixing frame.

[0010] Preferably, there are a number of negative pressure cylinders. The number of negative pressure cylinders are horizontally distributed along the inner surface of the conveyor belt and cover the conveying range of the conveyor belt.

[0011] Preferably, an inner cylinder is provided inside the negative pressure cylinder. An air suction hole is opened at the top of the inner cylinder. The through holes on the negative pressure cylinder are arranged in a complete circle. When the through hole rotates with the negative pressure cylinder to the highest point of the negative pressure cylinder, the through hole communicates with the air suction hole. One end of the inner cylinder is connected with a negative pressure pipe, and the bottom end of the negative pressure pipe is connected with the negative pressure end of the negative pressure pump. When the negative pressure holes on the conveyor belt, the communication holes on the backing plate, the through holes on the negative pressure cylinder, and the air suction holes on the inner cylinder are communicated, the negative pressure pump starts to work to form a negative pressure space in the space formed by the negative pressure holes, the communication holes, the through holes, and the air suction holes.

[0012] Preferably, an arc-shaped groove is opened on the outer wall of the switching shaft. The arc-shaped groove corresponds to the bottom end of the negative pressure pipe. One end of the switching shaft is provided with a female plug sleeve. The negative pressure end of the negative pressure pump is connected with a male plug sleeve. The male plug sleeve is inserted into the female plug sleeve. A fixed pipe is connected between the male plug sleeve and the negative pressure pump. The fixed pipe is fixedly connected with the negative pressure pipe at the discharging end of the conveyor belt. Arc-shaped pieces are arranged at the bottoms of several other negative pressure pipes. The arc-shaped pieces cover the opening size of the arc-shaped groove. There are three arc-shaped grooves on the switching shaft, and the positions correspond to the three negative pressure cylinders, configured such that the negative pressure cylinders at the feeding end and the discharging end of the conveyor belt can sequentially form negative pressure.

[0013] On the other hand, the present invention provides a conveying method based on the processing of high-strength non-ferrous metal aluminum plates, including the following steps: S1. Drive the conveyor belt with a vertical bending part to circulate through the conveying rollers, so that a continuous moving bearing surface is formed on the outer surface of the conveyor belt; S2. Start the adsorption device to generate negative pressure, so that the negative pressure channel communicates with the negative pressure holes on the conveyor belt. When the metal aluminum plate is placed on the bearing surface of the conveyor belt, the negative pressure holes contact the metal aluminum plate to form a sealed space, and the metal aluminum plate is fixed by negative pressure adsorption; S3. Synchronously drive the flattening roller and the conveying roller to rotate in the same direction. Use the flattening roller to flatten the vertical bending part of the conveyor belt. At the same time, send gas into the inner cavity of the flattening roller through the positive pressure generated by the adsorption device, so that the gas blows to the outer surface of the conveyor belt.

[0014] Compared with the prior art, the present invention can at least achieve one of the following beneficial effects: 1. In the present invention, the capillary adsorption cotton is arranged in a bidirectional spiral layout and rotates synchronously with the flattening roller to form a uniform adsorption liquid coating on the surface of the conveyor belt. This structure utilizes the surface tension adjustment characteristics of soapy water or low-viscosity silicone oil to form a dense liquid film layer on the contact surface between the metal aluminum plate and the conveyor belt, effectively eliminating tiny gaps. Cooperating with the negative pressure adsorption device, it significantly improves the stability of the metal aluminum plate during high-speed conveying, avoiding displacement problems caused by air flow disturbance, and is especially suitable for the precise conveying scenario of thin aluminum plates in an automated three-dimensional warehouse. 2. The bidirectional spiral groove structure of the present invention combines the functions of leveling, cleaning, and film covering. During the rotation of the leveling roller, the spiral grooves guide the conveyor belt material to generate bidirectional stretching stress, effectively eliminating local wrinkles on the conveyor belt caused by long-term use. At the same time, the air blowing holes in the spiral grooves form a directional air flow, which, in cooperation with the leveling action, strips off the residual particulate matter on the surface of the conveyor belt, maintains the cleanliness of the contact surface, and ensures the long-term effective operation of the negative pressure adsorption system; 3. The present invention realizes the continuous adsorption of metal aluminum sheets by adopting a dynamic negative pressure control system. Through the mechanical coupling design of the negative pressure cylinder and the switching shaft, the negative pressure pump is alternately connected to the negative pressure cylinders in different regions. This mechanical switching mechanism effectively solves the pressure fluctuation problem existing in the traditional vacuum adsorption system, ensures that the conveyor belt maintains a stable negative pressure in each working section, is particularly suitable for long-distance continuous conveying operation environments, and can save energy; 4. Through the compound transmission design of bevel gears and spur gears, the leveling roller of the present invention simultaneously has three functions: rotary leveling, adsorption liquid coating, and air flow cleaning. This integrated drive scheme significantly simplifies the mechanical structure, ensures that each functional unit maintains precise rotational speed synchronization, effectively reduces the complexity of equipment maintenance, and improves the overall reliability of the system.

Detailed Embodiments

[0018] The following will specifically describe the preferred embodiments of the present invention with reference to the accompanying drawings, where the accompanying drawings form a part of the present invention and are used together with the embodiments of the present invention to explain the principle of the present invention.

[0019] Embodiment 1: As Figure 1 , Figure 2 , Figure 3As shown in the figure, this embodiment provides a conveying device for processing high-strength non-ferrous metal aluminum plates, which is used to convey the metal aluminum plates 3 processed by the processing equipment 2. The conveying device includes a conveyor belt 1 and conveying rollers 4. The conveyor belt 1 is divided into an outer surface and an inner surface. The outermost outer surface is used to carry the metal aluminum plates 3. The conveyor belt 1 moves under the drive of the conveying rollers 4. A number of negative pressure holes 5 are provided in the conveyor belt 1. The outer surface of the conveyor belt 1 is used to carry the metal aluminum plates 3. At least a part of the conveyor belt 1 has a vertical bending part. A leveling roller 6 that rotates in the same direction as the conveying roller 4 is provided on the outer wall of the vertical bending part. The leveling roller 6 is located on the outer surface of the conveyor belt 1. An adsorption device is installed on the inner surface of the conveyor belt 1, and the adsorption device can form positive pressure and negative pressure; Among them, the adsorption device forms a negative pressure channel and is connected to the negative pressure holes 5 on the conveyor belt 1. The adsorption device forms a positive pressure channel and is connected to the inner cavity of the leveling roller 6; The outer ends of the negative pressure holes 5 abut against the metal aluminum plates 3, so that negative pressure is formed in the negative pressure holes 5 to adsorb the metal aluminum plates 3.

[0020] As Figure 4 shown in the figure, the conveyor belt 1 sequentially forms a continuous conveying part 1a, a vertical conveying part 1b, a horizontal conveying part 1c and a vertical bending part in the counterclockwise order. The vertical bending part is divided into a vertical bending part 1d and a horizontal bending part 1e.

[0021] As a possible embodiment, as Figure 5 shown in the figure, the leveling roller 6 is provided with a bidirectional spiral groove 7. A number of air blowing holes 9 are provided in the grooves of the bidirectional spiral groove 7. The air blowing holes 9 are communicated with the inner cavity 8 of the leveling roller 6.

[0022] A capillary adsorption cotton 10 is connected to the leveling roller 6. The capillary adsorption cotton 10 is arranged in a bidirectional symmetric spiral on the leveling roller 6. The bidirectionally spirally arranged capillary adsorption cotton 10 converges in the middle of the leveling roller 6. An adsorption liquid is coated on the capillary adsorption cotton 10. The capillary adsorption cotton 10 contacts the outer surface of the conveyor belt 1, so as to coat the adsorption liquid on the outer surface of the conveyor belt 1. The adsorption liquid can be pure water, soapy water or low-viscosity silicone oil; In the above solution, since the surfactant (such as sodium stearate) in soapy water can significantly reduce the surface tension of water, the surface tension of water is relatively high, which makes it difficult for water to spread evenly between the suction cup and the contact surface, and it is easy to leave small bubbles to damage the vacuum seal. The hydrophilic end (carboxylate group) and hydrophobic end (hydrocarbon group) in the soap molecular structure will be arranged directionally on the liquid surface, reducing the cohesion between water molecules and making the liquid easier to spread into a thin layer. This characteristic enables the bottom of the metal aluminum plate 3 to fit more closely to the outer surface of the conveyor belt 1. Cooperating with the negative pressure holes 5 and the adsorption device, it can quickly discharge air and form an effective air pressure difference.

[0023] Below the leveling roller 6, there is an adsorption liquid storage tank 11 for storing the adsorption liquid. The storage tank 11 is filled with the adsorption liquid. Inside the storage tank, there is a liquid guiding block 12 made of cotton fiber material. The liquid guiding block 12 is connected to the bottom of the inner wall of the storage tank 11 through a spring (not shown in the figure), so that the top of the liquid guiding block 12 always abuts against the lower part of the capillary adsorption cotton 10.

[0024] As a possible embodiment, as Figure 3 , Figure 6 , Figure 7 shown, the adsorption device includes: A negative pressure pump 13, installed below the conveyor belt 1; A negative pressure cylinder 14, installed on the inner surface of the conveyor belt 1, with a number of through holes 15 opened around it. One end of the negative pressure cylinder 14 is connected to the negative pressure end of the negative pressure pump 13; A backing plate 16, arranged between the negative pressure cylinder 14 and the conveyor belt 1. The middle of the backing plate 16 has a communication hole 17; A fixing frame 18, placed on the ground. Both ends of the negative pressure cylinder 14, the backing plate 16, the conveying roller 4 and the leveling roller 6 are rotatably connected to the fixing frame 18.

[0025] There are a number of negative pressure cylinders 14, and the number of negative pressure cylinders 14 are horizontally distributed along the inner surface of the conveyor belt 1 and cover the conveying range of the conveyor belt 1.

[0026] As a possible embodiment, as Figure 8 shown, an inner cylinder 19 is arranged inside the negative pressure cylinder 14. An air suction hole 20 is opened at the top of the inner cylinder 19. The through holes 15 on the negative pressure cylinder 14 are opened in a full circle. When the through hole 15 rotates with the negative pressure cylinder 14 to the highest point of the negative pressure cylinder 14, the through hole 15 communicates with the air suction hole 20; One end of the inner cylinder 19 is connected to a negative pressure pipe 21, and the bottom end of the negative pressure pipe 21 is connected to the negative pressure end of the negative pressure pump 13; As Figure 3 shown, in the above solution, when the negative pressure holes 5 on the conveyor belt 1, the communication holes 17 on the backing plate 16, the through holes on the negative pressure cylinder 14 and the air suction holes 20 on the inner cylinder 19 are in communication, the negative pressure pump 13 starts to work, forming a negative pressure space for the space formed by the negative pressure holes 5, the communication holes 17, the through holes 15 and the air suction holes 20. Thus, when the conveyor belt 1 drives the aluminum metal sheet 3 to be conveyed, the aluminum metal sheet 3 can be adsorbed on the conveyor belt 1, and it is not easy to tilt, ensuring the smooth transportation of the material.

[0027] As a way to drive the leveling roller 6, it can be as Figure 9 shown: Connect the leveling roller 6 and any one of the conveying rollers 4 with a transmission component at one end of the leveling roller 6. The transmission component can be a belt drive, a chain drive or other components with the same-direction transmission function; As another way to drive the leveling roller 6, it can be asFigure 10 , Figure 11 As shown in Figure 11 : At one end of the leveling roller 6, a first bevel gear 23 is connected. On one side of the first bevel gear 23, there is a motor 24. The motor 24 is fixed on the inner wall of the fixing frame 18. On the output shaft of the motor 24, a second bevel gear 29 and a first spur gear 25 are connected. Among them, the second bevel gear 29 meshes with the first bevel gear 23 to achieve vertical power transmission. At one end of the leveling roller 6, there is a switching shaft 26. On the outer wall of the switching shaft 26, a second spur gear 27 is connected. The second spur gear 27 meshes with the first spur gear 25. At one end of the leveling roller 6, there is an air inlet pipe 28. The other end of the air inlet pipe 28 is connected to the positive pressure end of the negative pressure pump 13. The air inlet pipe 28 is inserted from the inlet at one end of the leveling roller 6, configured such that the leveling roller 6 can rotate normally; In the above solution, the motor 24 drives the second bevel gear 29 to rotate, thereby causing the second bevel gear 29 to drive the first bevel gear 23 to rotate, thereby causing the leveling roller 6 to rotate, and thereby causing the capillary adsorption cotton 10 on the outer wall of the leveling roller 6 to scrape against the outside of the conveyor belt 1, and applying the adsorption liquid on the capillary adsorption cotton 10 to the outside of the conveyor belt 1; As an alternative solution, an electric heating wire (not shown in the figure) is installed in the inner cavity 8 of the leveling roller 6; Through the above solution, the following effects can be achieved: ① The capillary adsorption cotton 10 can apply the adsorption liquid to the outside of the conveyor belt 1, thereby providing a stronger adsorption effect; ② The capillary adsorption cotton 10 is further arranged in a double - helix shape, and the outer wall of the leveling roller 6 is also provided with double - helix grooves 7. Thus, when the leveling roller 6 rotates, the conveyor belt 1 can be leveled from the middle to both sides by the leveling roller 6, and the dust and other sundries on the conveyor belt 1 can be scraped from the middle to both sides, thereby ensuring the cleanliness and flatness of the outside of the conveyor belt 1, and thus better adsorption performance can be obtained; ③ Through the electric heating wire and the air blowing holes 9 opened in the double - helix grooves 7, when the high - pressure gas generated by the negative pressure pump 13 enters the inner cavity 8, the inner cylinder 19 blows the air to the outside of the conveyor belt 1 through the air blowing holes 9, thereby achieving the effects of dust blowing and heating (heating can enhance the fluidity of the low - viscosity silicone oil, so that the low - viscosity silicone oil can better spread on the outside of the conveyor belt 1).

[0028] As a possible embodiment, as Figure 12 , Figure 13 , Figure 14As shown in the figure, an arc-shaped groove 30 is formed in the outer wall of the switching shaft 26. The arc-shaped groove 30 corresponds to the bottom end of the negative pressure pipe 21. One end of the switching shaft 26 is provided with a female socket 31. The negative pressure end of the negative pressure pump 13 is connected with a male socket 32. The male socket 32 is inserted into the female socket 31. A fixing pipe 33 is connected between the male socket 32 and the negative pressure pump 13. The fixing pipe 33 is fixedly connected with the negative pressure pipe 21 at the discharging end of the conveyor belt 1. Arc-shaped pieces 34 are arranged at the bottoms of several other negative pressure pipes 21. The arc-shaped pieces 34 cover the opening size of the arc-shaped groove 30. In the above solution, since the conveyor belt 1 is continuously misaligned with the through holes 15 on the negative pressure cylinder 14, a continuous negative pressure can be formed inside the negative pressure cylinder 14 through the relatively long arc-shaped groove 30, so that the next group of negative pressure holes 5 can be continuously communicated with the through holes 15, so that the area on the conveyor belt 1 on the same negative pressure cylinder 14 can achieve continuous negative pressure. Taking the solution shown in the figure as an example, there are three arc-shaped grooves 30 on the switching shaft 26, and their positions correspond to the three negative pressure cylinders 14 (there are four negative pressure cylinders 14 in the figure, but one negative pressure cylinder 14 near the discharging end of the conveyor belt 1 is not mechanically coupled with the switching shaft 26, that is, the other three negative pressure cylinders 14 are mechanically coupled with the switching shaft 26). From the end direction of the switching shaft 26, the three arc-shaped grooves 30 are evenly distributed in a ring shape. When the switching shaft 26 rotates, the negative pressure cylinders 14 at the feeding end and the discharging end of the conveyor belt 1 can sequentially form negative pressure. It should be noted that in the above solution, in order to generate negative pressure at the place where the aluminum metal sheet 3 passes, the rotation speed of the switching shaft 26 is matched with the rotation speed of the conveyor belt 1.

[0029] As Figure 15 shown, at least a part of the fixing frame 18 is connected with a side plate 35. Both ends of the side plate 35 are connected with rotating sleeves 36. Both ends of the switching shaft 26 are connected with rotating rings 37. The rotating rings 37 rotate inside the rotating sleeves 36.

[0030] Embodiment 2: The technical solution of this embodiment is different from that of Embodiment 1 in that this embodiment provides a conveying method based on the processing of high-strength non-ferrous metal aluminum plates, including the following steps: S1. The conveying roller 4 starts to drive the conveyor belt 1 to rotate counterclockwise in a cycle, and the negative pressure pump 13 starts synchronously to establish negative pressure. The leveling roller 6 is driven by the motor 24 to drive the second bevel gear 29 to drive the first bevel gear 23 to start rotating. The bidirectional spiral groove 7 on its surface follows the capillary adsorption cotton 10. The liquid guide block 12 in the storage box 11 continuously supplies the adsorption liquid to the capillary adsorption cotton 10 under the action of the spring. When the leveling roller 6 rotates, it contacts the conveyor belt 1 through the capillary adsorption cotton 10 and evenly coats the adsorption liquid on the surface of the conveyor belt 1. If low-viscosity silicone oil is used, the heating wire in the inner cavity 8 of the leveling roller 6 starts to preheat. S2. The processed aluminum metal sheet 3 is fed into the feeding end of the conveyor belt 1. The surface of the conveyor belt 1 is adsorbed with liquid to fill the micropores on the surface of the conveyor belt 1. The negative pressure pump 13 applies negative pressure to the inner cylinder 19 through the negative pressure pipe 21. When the conveyor belt 1 moves to align the negative pressure holes 5 with the communication holes 17 of the backing plate 16, the through holes 15 of the negative pressure cylinder 14, and the suction holes 20 of the inner cylinder 19, a sealed negative pressure cavity is formed among the four, and the aluminum metal sheet 3 is fixed on the surface of the conveyor belt 1 by a strong adsorption force to eliminate the bubbles on the contact surface of the adsorbed liquid. S3. During the continuous movement of the conveyor belt 1, the double - helical grooves 7 of the leveling roller 6 apply a double - directional stretching force to the conveyor belt 1 to eliminate local wrinkles. At the same time, the inner cavity 8 of the leveling roller 6 receives the positive - pressure air flow of the negative pressure pump 13 through the air inlet pipe 28 and ejects a directional air flow from the air blowing holes 9 to remove the residual particles on the surface of the conveyor belt 1. The capillary adsorption cotton 10 continuously replenishes the adsorbed liquid to maintain the integrity of the liquid film. S4. The switching shaft 26 rotates synchronously with the rotation speed of the conveyor belt 1. The arc - shaped grooves 30 on its surface periodically communicate with the negative pressure pipes 21 of different negative pressure cylinders 14. When a certain group of negative pressure cylinders 14 moves away from the current adsorption area along with the conveyor belt 1, the arc - shaped grooves 30 establish a connection with the next negative pressure cylinder 14, realizing a seamless switching of the negative pressure channels and ensuring that the entire moving path of the aluminum metal sheet 3 is in a stable negative - pressure adsorption state. S5. When the aluminum metal sheet 3 is conveyed to the discharging end, the negative pressure pump 13 is turned off and the adsorption force is released.
