Description

Technical Field

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

[0002] Precision conveyors in automated warehouses are a core component of warehouse automation systems, primarily responsible for the efficient and precise transportation, storage, and retrieval of goods. Using rollers, chains, belts, or lifting mechanisms, they rapidly transport goods between warehouse areas (such as receiving, storage, and outbound), and collaborate with stacker cranes to automatically store and retrieve goods. Their precision is reflected in high-precision positioning, stable transmission, and seamless integration with control systems, ensuring that goods are transported without deviation or damage.

[0003] Base comprises support, castor, and frame upper is provided with guide rail, and support and conveyer frames movable end contact site are provided with recoil spring or rubber cushion, and castor is arranged on the pin of base bottom four, to carry mobile handler location.

[0004] In the precision conveying scenario of an automated high-bay warehouse, thin plates are relatively light, especially aluminum, which has a lower density than iron (7.8 g / cm³ vs. 2.7 g / cm³). Therefore, during transportation, aluminum plates may deviate from the conveyor belt, causing deviation in the transfer area. This can lead to offsets during the subsequent palletizing process in the automated high-bay warehouse, resulting in uneven palletizing. Existing technologies generally use baffles to solve this problem. However, after the baffles are set, the blocked area is inconvenient for personnel to observe and for subsequent mechanical equipment to pick it up. Summary of the Invention

[0005] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0006] The present invention provides a conveying device and method based on the processing of 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:

[0007] On the one hand, the present invention provides a conveying device based on the processing of high-strength non-ferrous metal aluminum plates, comprising a conveyor belt and a conveyor roller. The conveyor belt moves under the drive of the conveyor roller. A plurality of negative pressure holes are opened on the conveyor belt. The outer surface of the conveyor belt is used to carry the metal aluminum plates. At least a portion of the conveyor belt has a vertical bend. The outer wall of the vertical bend is provided with a leveling roller that rotates in the same direction as the conveyor roller. The leveling roller is located on the outer surface of the conveyor belt. An adsorption device is installed on the inner surface of the conveyor belt. The adsorption device generates positive and negative pressure.

[0008] Among them, the adsorption device forms a negative pressure channel and is connected to the negative pressure hole on the conveyor belt, and the adsorption device forms a positive pressure channel and is connected to the inner cavity of the leveling roller;

[0009] The outer end of the negative pressure hole is against the metal aluminum plate, so that negative pressure is formed in the negative pressure hole, which adsorbs the metal aluminum plate.

[0010] Preferably, the conveyor belt forms a continuous transmission portion, a vertical transmission portion, a horizontal transmission portion and a vertical bending portion in a counterclockwise order, and the vertical bending portion is a vertical bending portion and a horizontal bending portion.

[0011] Preferably, a bidirectional spiral groove is provided on the leveling roller, and a plurality of blowing holes are opened in the groove of the bidirectional spiral groove, and the blowing holes are communicated with the inner cavity of the leveling roller.

[0012] Preferably, the leveling roller is connected with capillary adsorption cotton, which is arranged in a bidirectional symmetrical spiral on the leveling roller. The bidirectional spirally arranged capillary adsorption cotton is gathered in the middle of the leveling roller, and the capillary adsorption cotton is coated with adsorption liquid.

[0013] Preferably, a storage box for storing the adsorption liquid is provided below the leveling roller, and an elastic liquid-conducting block is provided in the storage box. The liquid-conducting block is made of cotton fiber material, and the elastic liquid-conducting block is connected to the bottom of the inner wall of the storage box through a spring.

[0014] Preferably, the adsorption device comprises:

[0015] Negative pressure pump;

[0016] The negative pressure cylinder is installed on the inner surface of the conveyor belt and has a number of through holes around it. One end of the negative pressure cylinder is connected to the negative pressure end of the negative pressure pump;

[0017] A pad is provided between the negative pressure cylinder and the conveyor belt, and has a communicating hole in the middle of the pad;

[0018] The fixing frame, the negative pressure cylinder, the pad, the conveying roller and the two ends of the leveling roller are rotatably connected to the fixing frame.

[0019] Preferably, there are a plurality of negative pressure cylinders, which are distributed laterally along the inner surface of the conveyor belt and cover the conveying range of the conveyor belt.

[0020] Preferably, an inner cylinder is provided inside the negative pressure cylinder, an air suction hole is opened on the top of the inner cylinder, and the through hole on the negative pressure cylinder is opened in a full circle. When the through hole rotates to the highest point of the negative pressure cylinder with the negative pressure cylinder, the through hole is connected with the air suction hole; one end of the inner cylinder is connected with a negative pressure tube, and the bottom end of the negative pressure tube is connected to the negative pressure end of the negative pressure pump; when the negative pressure hole on the conveyor belt, the connecting hole on the pad, the through hole on the negative pressure cylinder and the air suction hole on the inner cylinder are connected, the negative pressure pump starts to work, and forms a negative pressure space in the space formed by the negative pressure hole, the connecting hole, the through hole and the air suction hole.

[0021] Preferably, an arc-shaped groove is provided on the outer wall of the switching shaft, which corresponds to the bottom end of the negative pressure tube. A plug-in sleeve is provided at one end of the switching shaft, and the negative pressure end of the negative pressure pump is connected to a plug-in sub-sleeve, which is inserted into the plug-in female sleeve. A fixed tube is connected between the plug-in sub-sleeve and the negative pressure pump, and the fixed tube is fixedly connected to the negative pressure tube at the unloading end of the conveyor belt. An arc-shaped sheet is provided at the bottom of several other negative pressure tubes, and the arc-shaped sheet covers the opening size of the arc-shaped groove. There are three arc-shaped grooves on the switching shaft, and their positions correspond to the three negative pressure cylinders, which are configured to form negative pressure in sequence from the negative pressure cylinders at the feeding end and the discharging end of the conveyor belt.

[0022] On the other hand, the present invention provides a conveying method based on high-strength non-ferrous metal aluminum plate processing, comprising the following steps:

[0023] S1. The conveyor belt with a vertical bending portion is driven to circulate through the conveyor roller so that the outer surface of the conveyor belt forms a continuously moving bearing surface;

[0024] S2. Start the adsorption device to generate negative pressure, so that the negative pressure channel is connected to the negative pressure hole on the conveyor belt. When the metal aluminum plate is placed on the carrying surface of the conveyor belt, the negative pressure hole contacts the metal aluminum plate to form a sealed space, and the metal aluminum plate is fixed by negative pressure adsorption;

[0025] S3. Synchronously drive the leveling roller and the conveying roller to rotate in the same direction, use the leveling roller to flatten the vertical bending part of the conveyor belt, and at the same time use the positive pressure generated by the adsorption device to transport gas to the inner cavity of the leveling roller, so that the gas is blown to the outside of the conveyor belt.

[0026] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0027] 1. This invention uses a bidirectional spiral layout of capillary adsorption cotton to rotate synchronously with the leveling roller, forming a uniform adsorption liquid coating on the conveyor belt surface. This structure utilizes the surface tension adjustment properties of soapy water or low-viscosity silicone oil to form a dense liquid film layer on the contact surface between the metal aluminum sheet and the conveyor belt, effectively eliminating tiny gaps. In combination with a negative pressure adsorption device, it significantly improves the stability of the metal aluminum sheet during high-speed conveying and avoids displacement problems caused by airflow disturbances. It is particularly suitable for the precise conveying of thin aluminum sheets in automated warehouses.

[0028] 2. The bidirectional spiral groove structure of the present invention combines the functions of leveling, cleaning, and coating. During the rotation of the leveling roller, the spiral groove guides the conveyor belt material to generate bidirectional stretch stress, effectively eliminating local wrinkles caused by long-term use of the conveyor belt. At the same time, the blowing holes in the spiral groove form a directional airflow, which cooperates with the leveling action to remove residual particles on the conveyor belt surface, maintain the cleanliness of the contact surface, and ensure the long-term and effective operation of the negative pressure adsorption system.

[0029] 3. The present invention achieves continuous adsorption of aluminum metal sheets by adopting a dynamic negative pressure control system. The mechanical coupling design of the negative pressure cylinder and the switching shaft enables the negative pressure pump to be alternately connected to the negative pressure cylinders in different areas. This mechanical switching mechanism effectively solves the pressure fluctuation problem existing in traditional vacuum adsorption systems, ensuring that each working section of the conveyor belt always maintains a stable negative pressure. It is particularly suitable for long-distance continuous conveying operations and can save energy.

[0030] 4. The present invention uses a composite transmission design of bevel gears and spur gears to enable the leveling roller to simultaneously perform the three functions of rotational leveling, adsorption liquid coating, and airflow cleaning. This integrated drive solution significantly simplifies the mechanical structure, ensures that each functional unit maintains precise speed synchronization, effectively reduces the complexity of equipment maintenance, and improves the overall reliability of the system.

[0031] Other features and advantages of the present invention will be described in the following embodiments, and some will become apparent from the description or understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the written description and the accompanying drawings.

DETAILED DESCRIPTION

[0050] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used to explain the principles of the present invention together with the embodiments of the present invention.

[0051] Example 1: Figure 1 、 Figure 2 、 Figure 3 As shown, this embodiment provides a conveying device based on high-strength non-ferrous metal aluminum plate processing, which is used to convey the metal aluminum plate 3 processed from the processing equipment 2. The conveying device includes a conveyor belt 1 and a conveyor roller 4. The conveyor belt 1 is divided into an outer surface and an inner surface. The outer surface of the top is used to carry the metal aluminum plate 3. The conveyor belt 1 moves under the drive of the conveyor roller 4. A plurality of negative pressure holes 5 are opened on the conveyor belt 1. The outer surface of the conveyor belt 1 is used to carry the metal aluminum plate 3. At least a portion of the conveyor belt 1 has a vertical bending portion. The outer wall of the vertical bending portion is provided with a leveling roller 6 that rotates in the same direction as the conveyor roller 4. The leveling roller 6 is located on the outer surface of the conveyor belt 1. The inner surface of the conveyor belt 1 is installed with an adsorption device, which can form positive pressure and negative pressure.

[0052] Among them, the adsorption device forms a negative pressure channel and is connected to the negative pressure hole 5 on the conveyor belt 1, and the adsorption device forms a positive pressure channel and is connected to the inner cavity of the leveling roller 6;

[0053] The outer end of the negative pressure hole 5 abuts against the metal aluminum plate 3, so that a negative pressure is formed in the negative pressure hole 5, which adsorbs the metal aluminum plate 3.

[0054] like Figure 4 As shown, the conveyor belt 1 forms a continuous transmission portion 1a, a vertical transmission portion 1b, a horizontal transmission portion 1c and a vertical bending portion in a counterclockwise order, and the vertical bending portion is a vertical bending portion 1d and a horizontal bending portion 1e.

[0055] As a possible embodiment, Figure 5As shown, the leveling roller 6 is provided with a bidirectional spiral groove 7 , and a plurality of blowing holes 9 are opened in the groove of the bidirectional spiral groove 7 , and the blowing holes 9 are communicated with the inner cavity 8 of the leveling roller 6 .

[0056] The leveling roller 6 is connected to a capillary adsorption cotton 10, which is arranged in a bidirectional symmetrical spiral on the leveling roller 6. The bidirectional spiral capillary adsorption cotton 10 is gathered in the middle of the leveling roller 6. The capillary adsorption cotton 10 is coated with an adsorption liquid. The capillary adsorption cotton 10 contacts the outside of the conveyor belt 1, thereby applying the adsorption liquid to the outside of the conveyor belt 1. The adsorption liquid can be pure water, soapy water or low-viscosity silicone oil.

[0057] In the above scheme, since the surfactant (such as sodium stearate) in the soapy water can significantly reduce the surface tension of water, the surface tension of water is relatively high, which makes it difficult to spread evenly between the suction cup and the contact surface, and it is easy for tiny bubbles to remain and destroy the vacuum seal. The hydrophilic end (carboxylate) and hydrophobic end (hydrocarbon group) in the soap molecular structure will be oriented on the liquid surface, reducing the cohesive force between water molecules and making the liquid easier to stretch into a thin layer. This characteristic enables the bottom of the metal aluminum plate 3 to fit more closely to the outside of the conveyor belt 1, and cooperate with the negative pressure hole 5 and the adsorption device to quickly discharge air and form an effective air pressure difference.

[0058] A storage box 11 for storing adsorption liquid is provided below the leveling roller 6. The storage box 11 is filled with adsorption liquid. The storage box has a liquid guide block 12. The liquid guide block 12 is made of cotton fiber material. The liquid guide block 12 is connected to the bottom of the inner wall of the storage box 11 through a spring (not shown in the figure), so that the top of the liquid guide block 12 is always in contact with the lower part of the capillary adsorption cotton 10.

[0059] As a possible embodiment, Figure 3 、 Figure 6 、 Figure 7 As shown, the adsorption device includes:

[0060] A negative pressure pump 13 is installed below the conveyor belt 1;

[0061] The negative pressure cylinder 14 is installed on the inner surface of the conveyor belt 1 and has a plurality of through holes 15 around it. One end of the negative pressure cylinder 14 is connected to the negative pressure end of the negative pressure pump 13.

[0062] A backing plate 16 is provided between the negative pressure cylinder 14 and the conveyor belt 1, and a communication hole 17 is provided in the middle of the backing plate 16;

[0063] The fixing frame 18 is placed on the ground, and both ends of the negative pressure cylinder 14 , the pad 16 , the conveying roller 4 and the leveling roller 6 are rotatably connected to the fixing frame 18 .

[0064] There are a plurality of negative pressure cylinders 14 , which are distributed transversely along the inner surface of the conveyor belt 1 and cover the conveying range of the conveyor belt 1 .

[0065] As a possible embodiment, Figure 8 As shown, an inner cylinder 19 is provided inside the negative pressure cylinder 14, and an air suction hole 20 is opened at the top of the inner cylinder 19. The through hole 15 on the negative pressure cylinder 14 is 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 is connected to the air suction hole 20; one end of the inner cylinder 19 is connected to the negative pressure tube 21, and the bottom end of the negative pressure tube 21 is connected to the negative pressure end of the negative pressure pump 13;

[0066] like Figure 3 As shown, in the above scheme, when the negative pressure hole 5 on the conveyor belt 1, the connecting hole 17 on the pad 16, the through hole on the negative pressure cylinder 14 and the suction hole 20 on the inner cylinder 19 are connected, the negative pressure pump 13 starts to work, and forms a negative pressure space in the space formed by the above negative pressure hole 5, the connecting hole 17, the through hole 15 and the suction hole 20, so that when the conveyor belt 1 drives the metal aluminum plate 3 to be transported, the metal aluminum plate 3 can be adsorbed on the conveyor belt 1, and the tilting problem is not likely to occur, thereby ensuring smooth material transportation.

[0067] As a way of driving the leveling roller 6, it can be as follows Figure 9 As shown: a transmission assembly is used to connect one end of the leveling roller 6 and any one of the conveying rollers 4. The transmission assembly can be a belt drive, a chain drive or other components with a same-direction transmission function;

[0068] As another way to drive the leveling roller 6, it can be as follows Figure 10 、 Figure 11 As shown: a first bevel gear 23 is connected to one end of the leveling roller 6, a motor 24 is provided on one side of the first bevel gear 23, the motor 24 is fixed to the inner wall of the fixing frame 18, and a second bevel gear 29 and a first spur gear 25 are connected to the output shaft of the motor 24, wherein the second bevel gear 29 is meshed with the first bevel gear 23 to realize vertical power transmission, a switching shaft 26 is provided at one end of the leveling roller 6, the outer wall of the switching shaft 26 is connected to the second spur gear 27, the second spur gear 27 is meshed with the first spur gear 25, an air intake pipe 28 is provided at one end of the leveling roller 6, the other end of the air intake pipe 28 is connected to the positive pressure end of the negative pressure pump 13, the air intake pipe 28 is inserted from the inlet at one end of the leveling roller 6, and is configured so that the leveling roller 6 can rotate normally;

[0069] In the above scheme, the second bevel gear 29 is driven to rotate by the motor 24, thereby causing the second bevel gear 29 to drive the first bevel gear 23 to rotate, thereby causing the leveling roller 6 to rotate, so that the capillary adsorption cotton 10 on the outer wall of the leveling roller 6 scrapes against the outer surface of the conveyor belt 1, and the adsorption liquid on the capillary adsorption cotton 10 is applied to the outer surface of the conveyor belt 1;

[0070] As an optional solution, the inner cavity 8 of the leveling roller 6 is equipped with a heating wire (not shown in the figure);

[0071] Through the above solution, the following effects can be achieved:

[0072] 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;

[0073] ② The capillary adsorption cotton 10 is further configured into a bidirectional spiral shape, and the outer wall of the leveling roller 6 is also provided with a bidirectional spiral groove 7, so that when the leveling roller 6 is rotating, the conveyor belt 1 can be smoothed from the middle to both sides by the leveling roller 6, and the dust and other debris on the conveyor belt 1 can be scraped off from the middle to both sides, thereby ensuring the cleanliness and flatness of the outer surface of the conveyor belt 1, thereby achieving better adsorption performance;

[0074] ③ Through the electric heating wire and the blowing hole 9 opened inside the bidirectional spiral groove 7, when the negative pressure pump 13 generates high-pressure gas and enters the inner cavity 8, the inner cylinder 19 blows the air to the outside of the conveyor belt 1 through the blowing hole 9, thereby achieving the dust blowing and heating effects (heating can enhance the fluidity of the low-viscosity silicone oil, so that the low-viscosity silicone oil can be better spread on the outside of the conveyor belt 1).

[0075] As a possible embodiment, Figure 12 、 Figure 13 、 Figure 14 As shown, an arc-shaped groove 30 is provided on the outer wall of the switching shaft 26, and the arc-shaped groove 30 corresponds to the bottom end of the negative pressure tube 21. A plug-in female sleeve 31 is provided at one end of the switching shaft 26. The negative pressure end of the negative pressure pump 13 is connected to a plug-in sub-sleeve 32, and the plug-in sub-sleeve 32 is inserted into the plug-in female sleeve 31. A fixed tube 33 is connected between the plug-in sub-sleeve 32 and the negative pressure pump 13. The fixed tube 33 is fixedly connected to the negative pressure tube 21 at the unloading end of the conveyor belt 1. An arc-shaped sheet 34 is provided at the bottom of the other several negative pressure tubes 21. The arc-shaped sheet 34 covers the opening size of the arc-shaped groove 30.

[0076] In the above solution, since the conveyor belt 1 is continuously misaligned with the through holes 15 on the negative pressure cylinder 14, the long arc-shaped groove 30 allows the negative pressure to be continuously formed inside the negative pressure cylinder 14, and can continue until the next set of negative pressure holes 5 is connected with the through holes 15, so that the area on the conveyor belt 1 on the same negative pressure cylinder 14 can achieve uninterrupted negative pressure.

[0077] Taking the scheme shown in the figure as an example, there are three arc-shaped grooves 30 on the switching shaft 26, and the positions correspond to the three negative pressure cylinders 14 (there are four negative pressure cylinders 14 in the figure, but the negative pressure cylinder 14 near the discharge end of the conveyor belt 1 is not mechanically coupled to the switching shaft 26, that is, the other three negative pressure cylinders 14 are mechanically coupled to the switching shaft 26). The three arc-shaped grooves 30 are evenly distributed in an annular shape when viewed from the end direction of the switching shaft 26. In this way, when the switching shaft 26 rotates, the negative pressure cylinders 14 at the feed end and the discharge end of the conveyor belt 1 can form negative pressure in sequence;

[0078] It should be noted that, in the above solution, in order to generate negative pressure where the metal aluminum plate 3 passes, the rotation speed of the switching shaft 26 is matched according to the rotation speed of the conveyor belt 1 .

[0079] like Figure 15 As shown, at least a portion of the fixing frame 18 is connected to a side plate 35 , both ends of the side plate 35 are connected to a rotating sleeve 36 , and both ends of the switching shaft 26 are connected to a rotating ring 37 , which rotates inside the rotating sleeve 36 .

[0080] Embodiment 2: This embodiment differs from the embodiment 1 in that it provides a conveying method based on the processing of high-strength non-ferrous metal aluminum plates, comprising the following steps:

[0081] S1: The conveyor roller 4 starts to drive the conveyor belt 1 to circulate counterclockwise. The negative pressure pump 13 starts synchronously to establish negative pressure. The leveling roller 6 drives the second bevel gear 29 through the motor 24 to drive the first bevel gear 23 to start rotating. The bidirectional spiral groove 7 on its surface and the capillary adsorption cotton 10 follow. 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 the adsorption liquid is evenly applied to the surface of the conveyor belt 1. If low-viscosity silicone oil is used, the heating wire 8 in the inner cavity of the leveling roller 6 starts to preheat.

[0082] S2. The processed metal aluminum sheet 3 is fed into the feeding end of the conveyor belt 1. The surface of the conveyor belt 1 absorbs liquid, filling 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 so that the negative pressure hole 5 is aligned with the connecting hole 17 of the pad 16, the through hole 15 of the negative pressure cylinder 14, and the suction hole 20 of the inner cylinder 19, the four form a closed negative pressure chamber. The metal aluminum sheet 3 is fixed to the surface of the conveyor belt 1 by the strong adsorption force, eliminating bubbles on the contact surface of the adsorption liquid;

[0083] S3: During the continuous movement of the conveyor belt 1, the bidirectional spiral groove 7 of the leveling roller 6 applies a bidirectional 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 airflow from the negative pressure pump 13 through the air inlet pipe 28, and a directional airflow is ejected from the blowing hole 9 to remove residual particles on the surface of the conveyor belt 1. The capillary adsorption cotton 10 continuously applies the adsorption liquid to maintain the integrity of the liquid film.

[0084] S4. The switching shaft 26 rotates synchronously with the speed of the conveyor belt 1. The arc groove 30 on its surface periodically connects the negative pressure tubes 21 of different negative pressure cylinders 14. When a group of negative pressure cylinders 14 moves out of the current adsorption area along with the conveyor belt 1, the arc groove 30 establishes a connection with the next negative pressure cylinder 14, realizing seamless switching of the negative pressure channel, ensuring that the metal aluminum plate 3 is in a stable negative pressure adsorption state throughout the entire moving path;

[0085] S5. When the metal aluminum plate 3 is transported to the discharge end, the negative pressure pump 13 is turned off and the adsorption force is released.
