Description

Technical Field

[0001] The present invention relates to the technical field of automated shoe production equipment, and in particular to a cloth wheel cleaning device and method. Background Art

[0002] During the production process of footwear products, a cloth wheel is needed to polish the surface of the secondary foamed shoe material. After a period of polishing, some of the fluff on the cloth wheel will fall off due to friction. Due to the high temperature generated during polishing, the burrs on the surface of the shoe material melt and adhere to the surface of the cloth wheel. When the temperature drops, they condense into gelatinous lumps.

[0003] In existing technology, to remove the glue bumps on the surface of a cloth wheel, a worker would scrape a saw blade back and forth across the high-speed rotating cloth wheel. This method not only removes the glue bumps on the cloth wheel's surface, but also increases the length of the surface fuzz, enhancing the cloth wheel's polishing effect. This process is called cloth wheel cleaning. However, manual cleaning is not only inefficient but also labor-intensive, which is inconsistent with the development of production automation.

[0044] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many other forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0045] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0047] The embodiments of the present invention provide a cloth wheel cleaning device and method for solving the problems of low cleaning efficiency and high labor intensity of workers in manual cleaning of cloth wheels in the prior art.

[0048] In the embodiment of the present invention, please refer to Figure 1 The cloth wheel cleaning device includes a frame 10, a detection assembly 20, and a cleaning assembly 30. The detection assembly 20 and the cleaning assembly 30 are both arranged on the frame 10. The detection assembly 20 is used to detect the pressure value when pressing against the cloth wheel; the cleaning assembly 30 is used to rub against the cloth wheel to clean the cloth wheel.

[0049] Please refer to Figure 2 The specific method of using the cloth wheel cleaning device to clean the cloth wheel is as follows:

[0050] S1: Set parameters, including the standard radius of the cloth wheel, the first standard distance and the second standard distance. The first standard distance is the distance the cloth wheel needs to move when it descends from the detection origin to the distance it presses against the detection component 20. The second standard distance is the distance the cloth wheel with a standard radius needs to move when it descends from the cleaning origin to the distance it presses against the cleaning component 30.

[0051] In step S1, the movement trajectory of the cloth wheel toward the detection assembly 20 or the cleaning assembly 30 is not limited, and its movement trajectory can be specifically determined according to the position layout of the detection assembly 20 and the cleaning assembly 30. The "descent" when describing the movement of the cloth wheel refers to the position relative to the detection assembly 20 and the cleaning assembly 30, and is not limited to the vertical movement in a decisive sense. Therefore, although Figure 1The detection component 20 and the cleaning component 30 shown in the figure require the cloth wheel to move in the vertical direction to press against the detection component 20 and the cleaning component 30. In other layouts, such as when at least one of the detection component 20 or the cleaning component 30 is arranged in the horizontal direction, then "descending" refers to movement in the horizontal direction.

[0052] S21: Move multiple cloth wheels with different radii in turn from the detection origin to the first standard distance, so that the cloth wheels are pressed against the detection component 20. The detection component 20 detects the pressure value at this time, thereby measuring multiple pressure values ​​corresponding to the cloth wheel radius. According to the pressure value obtained by the detection component 20 and the corresponding cloth wheel radius, a functional relationship between the cloth wheel radius and the pressure value at the first standard distance is fitted. The cloth wheel to be cleaned is lowered from the detection origin to the first standard distance, so that it is pressed against the detection component 20. The detection component 20 measures the actual pressure value. According to the actual pressure value and the functional relationship, the actual radius of the cloth wheel to be cleaned can be obtained. The standard radius is subtracted from the actual radius to obtain the radius difference, and the second standard distance is added to the radius difference to obtain the actual descending distance.

[0053] In step S21, since cloth wheels of different radii need to be pressed against the detection assembly 20 in the process of fitting the functional relationship between the cloth wheel radius and the pressure value, the first standard distance should be able to ensure that the cloth wheel with the smallest radius and the cloth wheel with the smaller radius to be cleaned can be pressed against the detection assembly 20 to obtain the pressure value during the test. Based on the same first standard distance, as the cloth wheel size decreases, the deformation or strain of the detection assembly caused by the cloth wheel pressing against the detection assembly 20 also decreases accordingly, and the measured pressure value also decreases accordingly. Generally speaking, the radius of the cloth wheel with the smallest radius used in the test process should be smaller than the radius of the cloth wheel to be cleaned, so that the fitted functional relationship can more accurately cover the correspondence between the radius of the cloth wheel to be cleaned and the pressure value.

[0054] Step S21 may also be replaced by step S22, specifically:

[0055] S22: Mark the pressure value generated when the cloth wheel with a standard radius is lowered by the first standard distance as the standard pressure value, lower the cloth wheel to be cleaned from the detection origin to press the detection component until the pressure value generated on the detection component is equal to the standard pressure value, mark the distance that the cloth wheel to be cleaned is lowered at this time as the detection distance, subtract the detection distance from the first standard distance to obtain the distance difference, add the distance difference to the standard radius to obtain the actual radius of the cloth wheel to be cleaned, subtract the actual radius from the standard radius to obtain the radius difference, and add the radius difference to the second standard distance to obtain the actual descending distance.

[0056] In the above steps, the standard radius refers to the cloth wheel radius value defined by the operator. The standard radius serves as the basis for determining the second standard distance. In other words, the second standard distance is the distance value corresponding to the standard radius. When the radius of the cloth wheel to be cleaned is different from the standard radius, the distance the cloth wheel to be cleaned moves from the cleaning origin to the cleaning assembly 30 needs to be corrected based on the second standard distance. Specifically, when the radius of the cloth wheel to be cleaned is greater than the standard radius, the cloth wheel needs to move a shorter distance to press against the cleaning assembly 30. In this case, the radius difference obtained in step S21 or S22 is a negative value, and the cloth wheel needs to move a shorter distance to press against the cleaning assembly 30. Therefore, the second standard distance is added to the radius difference to obtain the corrected distance value. When the radius of the cloth wheel to be cleaned is less than the standard radius, the cloth wheel needs to move a longer distance to press against the cleaning assembly 30, and the radius difference is a positive value. Therefore, the second standard distance is also added to the radius difference to obtain the corrected distance value. Generally speaking, the standard radius can be set to the radius of the cloth wheel that has not been polished. The radius of the cloth wheel to be cleaned is usually smaller than the standard radius due to the loss of cloth wheel material caused by polishing (the loss of cloth wheel material caused by polishing is often greater than the amount of glue lumps attached).

[0057] S3: Move the cloth wheel to be cleaned to the cleaning origin, and lower the cloth wheel to be cleaned by an actual lowering distance from the cleaning origin, so that the cloth wheel to be cleaned is pressed into contact with the cleaning component.

[0058] S4: The cloth wheel to be cleaned is rubbed against the cleaning component to clean the cloth wheel.

[0059] In the above method, it is necessary to drive the cloth wheel to perform various movements, which can be completed by the motion integration component. The positions of the detection origin and the cleaning origin can be determined by technical personnel according to the specific situation based on the motion range that the motion integration component can cover; and the setting of parameters, acquisition and processing of data, and motion control of the motion integration component can be completed by the microcontroller chip. The control logic of the microcontroller chip is the above-mentioned cloth wheel cleaning method.

[0060] Generally speaking, the motion integration component should include a moving component, a lifting component and a driving component. The moving component is used to drive the cloth wheel to move between the detection component 20 and the cleaning component 30. The lifting component is used to drive the cloth wheel to descend so that the cloth wheel is pressed against the detection component 20 or the cleaning component 30. The driving component is used to drive the cloth wheel to rotate. The specific structure of the motion integration component can adopt the more common design in the prior art, for example: the moving component is set as an electric cylinder mechanism, a synchronous belt mechanism or a chain transmission mechanism, the lifting component is set as a cylinder component controlled by an electromagnetic valve, and the driving component is set as a stepper motor or servo motor or other output rotation drive or a mechanism composed of such a drive and other transmission structures (turbine, worm, gear, etc.); at the same time, the moving component and the lifting component can also be integrated into a manipulator component with two degrees of freedom or three degrees of freedom. It is worth mentioning that in operations using a cloth wheel for grinding, the machine tool often already has a mechanical structure that can drive the cloth wheel to move and rotate. When the cloth wheel cleaning device provided by the present invention is used on these machine tools, these structures can be directly used on the premise that the original mechanical structure meets the cloth wheel movement requirements. If it does not meet the cloth wheel movement requirements, it can be improved on this basis to reduce the cost of modification while meeting the cloth wheel movement requirements.

[0061] The cloth wheel cleaning device and method place the cloth wheel on the detection component 20 to obtain a pressure value, and calculate the radius of the cloth wheel according to the pressure value, or calculate the radius of the cloth wheel by allowing the cloth wheel to generate a standard pressure value on the detection component, and then press the cloth wheel against the cleaning component 30 for cleaning according to the radius of the cloth wheel, thereby realizing automatic cleaning of the cloth wheel, reducing the labor intensity of workers, improving the cleaning efficiency of the cloth wheel, and overall increasing the degree of automation of the production process, thereby improving production efficiency.

[0062] Regarding step S3, moving the cloth wheel to be cleaned to the cleaning origin may include the following steps:

[0063] The cloth wheel to be cleaned, which is in press contact with the detection component 20, is moved from the detection component 20 to the cleaning origin; or the cloth wheel to be cleaned is lifted to the cleaning origin, and the frame 10 is rotated so that the detection component 20 and the cleaning component 30 exchange positions; or the cloth wheel to be cleaned is lifted to the cleaning origin, and the cleaning component 30 is moved so that the cleaning component 30 is located below the cleaning origin.

[0064] Regarding the method of rubbing the cloth wheel to be cleaned and the cleaning assembly 30 against each other in step S4, it may include the following steps:

[0065] Rotate the cloth wheel to be cleaned so that the cloth wheel to be cleaned and the cleaning assembly 30 rub against each other; and / or drive the components on the cleaning assembly 30 for rubbing the surface of the cloth wheel to be cleaned to move, so that the cloth wheel to be cleaned and the cleaning assembly 30 rub against each other. For example, when the cleaning assembly 30 includes a driving member and a soft rack, the driving member drives the soft rack to rotate and rub against the cloth wheel.

[0066] During the cloth wheel cleaning process, if the width of the contact area between the cloth wheel and the cleaning assembly 30 is smaller than the axial width of the cloth wheel, it is necessary to move the cloth wheel so that the entire surface of the cloth wheel can be cleaned. In this case, the cloth wheel cleaning method further includes the following steps:

[0067] When the cloth wheel to be cleaned and the cleaning assembly 30 are rubbed against each other, at least one of the cloth wheel to be cleaned or the cleaning assembly 30 is driven to translate left and right along the axis of the cloth wheel by a preset distance, so that the cleaning assembly 30 can clean different areas of the cloth wheel to be cleaned.

[0068] The radius of the cloth wheel will decrease due to the grinding operation, and after the cleaning operation, the radius will decrease further. The change in radius value will affect the grinding effect. Therefore, it is often necessary to compensate for the reduction in the radius of the cloth wheel. In response to the above problem, the cleaning method of the cloth wheel also includes the following steps:

[0069] S51: Move the cleaned cloth wheel to the detection origin and descend the first standard distance. The detection component 20 obtains the compensation pressure value, and obtains the radius of the cloth wheel after cleaning based on the compensation pressure value and the function relationship. The radius after cleaning can be used in subsequent grinding operations.

[0070] S51 can also be replaced by step S52, specifically:

[0071] S52: Move the cleaned cloth wheel to the detection origin, and descend from the detection origin to press the detection component until the pressure value generated on the detection component is equal to the standard pressure value. Mark the distance that the cloth wheel to be cleaned descends at this time as the compensation distance. Subtract the compensation distance from the first standard distance to obtain the distance compensation difference. Add the distance compensation difference to the standard radius to obtain the radius of the cloth wheel after cleaning. The radius after cleaning can be used in subsequent grinding operations.

[0072] It can be seen that step S51 is a subsequent solution based on step S21, and step S52 is a subsequent solution based on step S22.

[0073] Next, some embodiments of the cloth wheel cleaning device will be further described.

[0074] In one embodiment, the detection assembly 20 includes a pressure sensor 21 and a first drive assembly 22. The first drive assembly 22 is connected to the frame 10 and is electrically connected to the microcontroller chip. The pressure sensor 21 is connected to the output end of the first drive assembly 22. Under the control of the microcontroller chip, the first drive assembly 22 can drive the pressure sensor 21 to move between a recovery position and a detection position. In the recovery position, the pressure sensor 21 is lower than the work surface 111 of the frame 10. In the detection position, the pressure sensor 21 is higher than the work surface 111 of the frame 10. The pressure sensor 21 can be configured as one of a strain gauge pressure sensor, a piezoresistive pressure sensor, a capacitive pressure sensor, and a piezoelectric pressure sensor.

The second drive component 32 can drive the friction member 31 to move between the avoidance position and the cleaning position under the control of the microcontroller chip. In the avoidance position, the friction member 31 is lower than the work surface 111 of the frame 10. In the detection position, the friction member 31 is higher than the work surface 111 of the frame 10.

[0081] In the absence of a cleaning cloth wheel, the advantage of placing the cleaning assembly 30 below the work surface 111 is that it can avoid the movement of other devices on the production line, thereby facilitating the spatial layout and motion trajectory design of other devices.
