Description

Technical Field

[0001] The present invention relates to the field of air compressor tanks, and particularly to a control method and system for an energy-saving baking line of an air compressor tank. Background Art

[0002] An air compressor tank refers to an air compressor storage tank, which is a pressure vessel specifically used for storing compressed air.

[0003] In the production process of an air compressor tank, after the paint spraying is completed, it will enter the coating reinforcement stage. The tank body is moved into a special baking oven, where its internal heating elements and the circulating air duct work together to quickly create a high-temperature environment, allowing the coating to be fully heated, and the molecules to crosslink and stabilize, thereby enhancing the adhesion and wear resistance and ensuring the service performance of the tank body.

[0004] Currently, when the baking oven is heating, it usually adopts a heating method with a constant power. During the entire baking process, the heating equipment always operates at a fixed power. When heating different tank bodies and different coating thicknesses with a fixed power, the quality of the coating on the surface of the tank body is reduced, which needs to be improved. Summary of the Invention

[0005] In order to improve the quality of the coating on the surface of the tank body, the present invention provides a control method and system for an energy-saving baking line of an air compressor tank.

[0007] By adopting the above technical solution, after receiving the signal indicating that the spraying is completed, the transportation device is controlled to transport the tank body to the material suction area, and the arrival of the tank body is confirmed through the area signal, and then the material suction thin pipe is started to suck the material. After the material suction is completed, the transportation device is used again to send the tank body into the baking oven, and at the same time, the real-time baking temperature value of the baking oven and the coating parameters of the tank body are collected. Based on this, the required temperature value and the required baking duration are obtained. When the baking temperature of the baking oven reaches the required temperature value, the baking duration is started to be collected until the baking duration is consistent with the required baking duration, so as to ensure that the air compressor tank body is baked at an appropriate temperature and duration, so that the coating is fully cured and firmly attached, and the quality of the coating on the surface of the tank body is improved.

[0017] In summary, the present application includes at least one of the following beneficial technical effects: 1. By simultaneously collecting the real-time baking temperature value of the baking oven and the coating parameters of the tank body, the required temperature value and required baking duration are obtained. When the baking temperature of the baking oven reaches the required temperature value, the baking duration is collected until the baking duration is consistent with the required baking duration, so as to ensure that the air compressor tank body is baked at an appropriate temperature and duration, enabling the coating to be fully cured and firmly attached, and improving the quality of the tank body surface coating; 2. When the tank body does not contain additional components, further retrieve the spraying thickness value and the tank body size to generate the wrapping diameter of the thin tube, ensuring that the material suction thin tube can fit well with the surface of the tank body and absorb the excess paint to the greatest extent. Then, based on the tank body size and the material suction position of the tank body, obtain the initial arrival position and the upward movement distance of material suction, and further generate the pulling speed of the thin tube, which not only ensures sufficient absorption of the excess paint but also avoids affecting the material suction effect due to too fast or too slow speed. At the same time, displace upward at the upward movement speed of the thin tube, enabling the material suction process to fully cover the surface of the tank body, thereby avoiding paint waste and unevenness, and improving the flatness and uniformity of the coating on the surface of the tank body; 3. When the material spraying aggregation position is above the material suction thin tube, calculate the accelerated pulling speed and the accelerated pulling duration based on the water droplet size, the unit material suction amount, and the pulling speed of the thin tube, so as to control the material suction thin tube to be pulled at the accelerated pulling speed, which can ensure timely response when the sprayed material reaches the effective range of the material suction thin tube and improve the timeliness and effectiveness of material suction. After the end of the accelerated pulling duration, restore the pulling speed to the pulling speed of the thin tube to make the material suction process return to the normal state and ensure the stability and continuity of the material suction process.

[0020] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0021] Referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , an embodiment of the present application discloses a control method for an energy-saving baking line of an air compressor tank body, including the following steps: S1: In response to a preset spraying completion signal, control a preset transport device to transport the air compressor tank body 1 to a preset material suction area, and collect the area signal of the material suction area.

[0022] The spraying completion signal refers to the signal when the spraying operation on the air compressor tank body 1 is completed. The spraying completion signal is sent by a preset spraying device. The spraying device refers to a device used for spraying the outer surface of the air compressor tank body 1. The transport device refers to a device used for transporting the overall spraying process of the air compressor tank body 1. The material suction area refers to an area used for absorbing the materials that are redundantly sprayed on the outer surface of the air compressor tank body 1. The area signal refers to a signal used to detect whether the air compressor tank body 1 reaches the material suction area. The area signal is collected through a preset signal transceiver. The area signal includes a standby signal and an arrival signal. Among them, the standby signal refers to the signal when there is no air compressor tank body 1 in the material suction area. The arrival signal refers to the signal when there is an air compressor tank body 1 in the material suction area. The spraying material, the material suction area, the standby signal, and the arrival signal are all set in advance by those skilled in the art and will not be elaborated here.

[0023] When the spraying completion signal is received, it indicates that the spraying operation on the air compressor tank body 1 is completed. It is necessary to control the transport device to transport the air compressor tank body 1 to the material suction area and collect the area signal of the material suction area for subsequent steps.

[0024] S2: When the area signal is consistent with a preset arrival signal, control a preset suction capillary tube 3 to perform material suction in a preset material suction method.

[0025] When the area signal is consistent with the arrival signal, it indicates that the air compressor tank body 1 reaches the material suction area. The suction capillary tube 3 refers to a thin flexible hose used for absorbing the materials that are redundantly sprayed on the air compressor tank body 1. The material suction method refers to a method used for absorbing the materials that are redundantly sprayed on the air compressor tank body 1. The specific material suction method will be described in detail in subsequent steps S20 to S2117 and will not be elaborated here.

[0026] S3: When the material suction is completed, control the transport device to transport the air compressor tank body 1 into a preset baking oven 2, and collect the baking temperature value of the baking oven 2 and the tank body coating parameters of the air compressor tank body 1.

[0027] The baking oven 2 refers to a device used to bake the air compressor tank body 1 that has completed the spraying operation. The baking temperature value refers to the temperature value inside the baking oven 2. The tank body coating parameter refers to the thickness of the coating on the air compressor tank body 1. The baking temperature value is obtained through a preset temperature sensor on the baking oven 2. The tank body coating parameter is pre-entered by those skilled in the art.

[0028] After the material suction is completed, it is necessary to control the transportation device to transport the air compressor tank body 1 into the baking oven 2, and collect the baking temperature value of the baking oven 2 and the tank body coating parameters of the air compressor tank body 1 for subsequent steps.

[0029] S4: Generate the required temperature value and required baking duration based on the tank body coating parameters.

[0030] The required temperature value refers to the temperature value that needs to be reached inside the baking oven 2. The required baking duration refers to the duration for which baking needs to be carried out. The required temperature value and required baking duration corresponding to the tank body coating parameters can be queried through a preset baking comparison table, and this comparison table records the different required temperature values and required baking durations corresponding to different tank body coating parameters. The baking comparison table is formed by those skilled in the art recording the different required temperature values and required baking durations corresponding to different tank body coating parameters through successive experiments, which will not be elaborated here.

[0031] S5: When the baking temperature value is consistent with the required temperature value, collect the baking duration.

[0032] The baking duration refers to the duration for which the air compressor tank body 1 is baked inside the baking oven 2. The baking duration is obtained through an electronic timer on the baking oven 2.

[0033] When the baking temperature value is consistent with the required temperature value, it indicates that the temperature of the baking oven 2 has reached the standard, and it is necessary to collect the baking duration for subsequent steps.

[0034] S6: When the baking duration is consistent with the required baking duration, control the transportation device to transport the air compressor tank body 1 to a preset unloading area to complete the production of the air compressor tank body 1.

[0035] The unloading area refers to the area used to unload the air compressor tank body 1 that has completed baking. The unloading area is set in advance by those skilled in the art, which will not be elaborated here.

[0036] When the baking duration is consistent with the required baking duration, it indicates that the air compressor tank body 1 has completed baking, and it is necessary to control the transportation device to transport the air compressor tank body 1 to the unloading area for unloading to complete the production of the air compressor tank body 1.

[0037] Refer to Figure 2 and Figure 5 , the material suction method includes the following steps: S20: Collect the tank production information of the air compressor tank 1.

[0038] The tank production information refers to the information including parameters such as the model, size, weight, and structure of the air compressor tank 1. The tank production information is obtained by pre-input from the staff and will not be elaborated here.

[0039] S21: Based on the tank production information, determine whether the air compressor tank 1 includes the preset external tank components 6.

[0040] The external tank components 6 refer to the components provided on some air compressor tanks 1, excluding the cylinder of the tank body. For example, the fixing brackets and the base. By understanding the tank production information, the structure of the tank can be known, and thus it can be known whether the air compressor tank 1 includes the external tank components 6.

[0041] S210: When the air compressor tank 1 does not include the external tank components 6, based on the tank production information, retrieve the spraying thickness value and the tank size.

[0042] The spraying thickness value refers to the thickness value of the material sprayed on the outer surface of the air compressor tank 1. The tank size refers to the size of the air compressor tank 1 itself. The spraying thickness value and the tank size can be retrieved from the tank production information. The tank production information contains the spraying thickness value and the tank size.

[0043] When the air compressor tank 1 does not include the external tank components 6, it means that the air compressor tank 1 only has its own cylindrical tank body. When sucking materials into it, it is necessary to first retrieve the spraying thickness value and the tank size for subsequent steps.

[0044] S2100: Based on the tank size and the spraying thickness value, generate the diameter of the thin tube wrapping.

[0045] The diameter of the thin tube wrapping refers to the inner diameter after the suction thin tube 3 wraps around the tank. By understanding the tank size, the radius of the tank body itself can be known, and by further understanding the spraying thickness value, the radius of the tank after spraying can be obtained. Therefore, multiplying the sum of the radius of the tank body itself in the tank size and the spraying thickness value by 2 can obtain the diameter of the thin tube wrapping.

[0046] S2101: Based on the tank size and the preset tank material suction position, generate the initial arrival position and the upward movement distance for material suction.

[0047] The tank material suction position refers to the position that the tank needs to reach before the material suction operation. The tank material suction position is set in advance by those skilled in the art and will not be elaborated here. The initial arrival position refers to the position that the suction thin tube 3 needs to reach before the material suction operation. The upward movement distance for material suction refers to the distance that the suction thin tube 3 needs to move upward when sucking materials from bottom to top.

[0048] By knowing the material suction position of the tank body, the position of the tank body can be known. Combining the tank body size and the fact that the material suction thin pipe 3 moves upward from bottom to top for material suction, the position of the bottom of the tank body that the material suction thin pipe 3 needs to reach can be known, so as to obtain the initial arrival position. And by knowing the size of the tank body, the height of the tank body can be known, and thus the upward movement distance of the material suction can be known.

[0049] S2102: Respond to the diameter of the thin pipe wrapping to generate the pulling speed of the thin pipe.

[0050] When the material suction thin pipe 3 sucks the material of the tank body, it will wrap the tank body. Continuously pulling the thin pipe can make the material suction port change positions continuously, avoiding material accumulation caused by sucking material at the same place for a long time, and thus preventing the spraying material from blocking the material suction port. A notch for receiving the spraying material is opened on the material suction thin pipe 3. The excess spraying material will enter the material suction thin pipe 3 through the notch. One end of the material suction thin pipe 3 will drive the material suction thin pipe 3 to wrap the tank body. After completing the wrapping, this end will continuously receive the material suction thin pipe 3, and the other end will continuously output the material suction thin pipe 3 until the material suction is completed.

[0051] The pulling speed of the thin pipe refers to the horizontal pulling speed of the material suction thin pipe 3 when sucking material. Through a preset pulling comparison table, the pulling speed of the thin pipe corresponding to the diameter of the thin pipe wrapping can be queried. Different pulling speeds corresponding to different diameters of the thin pipe wrapping are recorded in this comparison table. The pulling comparison table is formed by the technicians in this field recording the different pulling speeds corresponding to different diameters of the thin pipe wrapping through successive tests, which will not be elaborated here.

[0052] S2103: Control the material suction thin pipe 3 to adjust the wrapping diameter to be consistent with the diameter of the thin pipe wrapping, then control the material suction thin pipe 3 to move to the initial arrival position, pull at the pulling speed of the thin pipe, and at the same time displace upward at a preset upward displacement speed of the thin pipe, so as to absorb the excess coating on the air compressor tank body 1.

[0053] The upward displacement speed of the thin pipe refers to the speed when the material suction thin pipe 3 displaces upward. The upward displacement speed of the thin pipe is set in advance by the technicians in this field, which will not be elaborated here.

[0054] Control the material suction thin pipe 3 to adjust the wrapping diameter to be consistent with the diameter of the thin pipe wrapping, then control the material suction thin pipe 3 to move to the initial arrival position, pull at the pulling speed of the thin pipe, and at the same time displace upward at the upward displacement speed of the thin pipe, so as to absorb the excess coating on the air compressor tank body 1.

[0055] Refer to Figure 3 and Figure 6 , the material suction method further includes the following steps: S211: When the air compressor tank body 1 includes the external components 6 of the tank body, based on the tank body production information, retrieve the spraying thickness value, the tank body size, the external component size, and the installation position of the external component.

[0056] The size of the external component refers to the size of the external component 6 of the tank body. The installation position of the external component refers to the position where the external component 6 of the tank body is installed on the tank body. By understanding the tank body production information, the spraying thickness value, the tank body size, the external component size, and the installation position of the external component can be retrieved. The tank body production information includes the spraying thickness value, the tank body size, the external component size, and the installation position of the external component.

[0057] When the air compressor tank body 1 includes the external component 6 of the tank body, it means that in addition to its own cylindrical tank body, the air compressor tank body 1 is additionally provided with other components. When feeding materials to it, it is necessary to retrieve the spraying thickness value, the tank body size, the external component size, and the installation position of the external component first for subsequent steps.

[0058] S2111: Generate the diameter of the thin tube wrapping based on the tank body size and the spraying thickness value.

[0059] This S is the same as the above S2100 and will not be elaborated here.

[0060] S2112: Generate the initial arrival position based on the tank body size and the preset tank body feeding position.

[0061] This S is the same as the above S2101 and will not be elaborated here.

[0062] S2113: Generate the pulling speed of the thin tube in response to the diameter of the thin tube wrapping.

[0063] This S is the same as the above S2102 and will not be elaborated here.

[0064] S2114: Generate the initial end position, the secondary arrival position, the secondary end position, the tertiary arrival position, and the tertiary end position based on the tank body size, the external component size, and the installation position of the external component.

[0065] The initial end position refers to the position where the feeding thin tube 3 ends when the feeding thin tube 3 moves upward to feed materials starting from the initial arrival position. The secondary arrival position refers to the position that the secondary feeding thin tube 4 needs to reach when feeding materials to the tank body. The secondary end position refers to the position where the secondary feeding thin tube 4 ends when the secondary feeding thin tube 4 moves upward to feed materials starting from the secondary arrival position. The tertiary arrival position refers to the position that the tertiary feeding thin tube 5 needs to reach when feeding materials to the tank body. The tertiary end position refers to the position where the tertiary feeding thin tube 5 ends when the tertiary feeding thin tube 5 moves upward to feed materials starting from the tertiary arrival position. The structures of the secondary feeding thin tube 4 and the tertiary feeding thin tube 5 are the same as the feeding thin tube 3 in the above S.

[0066] For the tank body with the external component 6 of the tank body, the feeding thin tube 3 cannot directly complete the feeding from bottom to top. Therefore, it is necessary to add a feeding thin tube 3 to assist in feeding.

[0067] By understanding the tank body dimensions, the height of the tank body can be known. Furthermore, by combining the positions of the external components, the maximum upward movement distance of the suction thin pipe 3 when it is not blocked can be calculated, and thus the initial end position can be determined. Based on the dimensions of the external components and their installation positions, the area of the tank body occupied by the external components 6 of the tank body can be known, and the upper and lower ends of the occupied area are the secondary arrival position and the secondary end position. After knowing the secondary end position, by understanding the dimensions of the external components, the thickness of the external components 6 of the tank body can be known. Moving the secondary end position upward by the thickness of the external components 6 of the tank body is the tertiary arrival position. Finally, by combining the remaining dimensions of the tank body, the tertiary end position can be obtained. The entire process requires the use of spatial geometry algorithms. Spatial geometry algorithms are common knowledge in this field and will not be elaborated here.

[0068] S2115: Control the suction thin pipe 3 to adjust the wrapping diameter to be consistent with the thin pipe wrapping diameter, and then control the suction thin pipe 3 to move to the initial arrival position. Pull at the thin pipe pulling speed and simultaneously displace upward at the preset thin pipe upward movement speed until reaching the initial end position.

[0069] Control the suction thin pipe 3 to adjust the wrapping diameter to be consistent with the thin pipe wrapping diameter, and then control the suction thin pipe 3 to move to the initial arrival position. Pull at the thin pipe pulling speed and simultaneously displace upward at the thin pipe upward movement speed until reaching the initial end position.

[0070] S2116: Control the preset secondary suction thin pipe 4 to move to the secondary arrival position, wrap the air compressor tank body 1 with the thin pipe wrapping diameter, then pull at the thin pipe pulling speed and simultaneously displace upward at the thin pipe upward movement speed until reaching the secondary end position.

[0071] Simultaneously control the secondary suction thin pipe 4 to move to the secondary arrival position, wrap the air compressor tank body 1 with the thin pipe wrapping diameter, then pull at the thin pipe pulling speed and simultaneously displace upward at the thin pipe upward movement speed until reaching the secondary end position.

[0072] S2117: Control the preset tertiary suction thin pipe 5 to move to the tertiary arrival position, wrap the air compressor tank body 1 with the thin pipe wrapping diameter, then pull at the thin pipe pulling speed and simultaneously displace upward at the thin pipe upward movement speed until reaching the tertiary end position.

[0073] Simultaneously control the tertiary suction thin pipe 5 to move to the tertiary arrival position, wrap the air compressor tank body 1 with the thin pipe wrapping diameter, then pull at the thin pipe pulling speed and simultaneously displace upward at the thin pipe upward movement speed until reaching the tertiary end position.

[0074] Refer to Figure 3 and Figure 7 , the suction method of the external components 6 of the tank body includes the following steps: S2118: Obtain an outward movement distance value based on the tank body material suction position, tank body size, external component size, and spraying thickness value.

[0075] The outward movement distance value refers to the distance that the spiral material suction device needs to move outward when separately sucking materials for the external component 6 of the tank body. The spiral material suction device refers to the device used for separately sucking materials for the external component 6 of the tank body.

[0076] Since the spiral material suction device is directly below the center of the tank body, the radius of the tank body itself can be known by understanding the tank body size, and the size of the external expansion of the tank body can be known by understanding the external component size. Finally, by adding the two values and the spraying thickness value, the size of the externally expanded tank body can be obtained.
