[0024] In order to solve the problem of frequently measuring drum diameter in the prior art, the present application provides a drum diameter detection method and a drum diameter detection device.

[0025] Embodiment 1

[0026] The drum diameter detection method includes a calibration process and an execution process. In the calibration process, the radius C1 of the drum plate is measured, the distance A1 between the detection member and the rotating shaft is obtained through the detection member, and the distance B1 between the detection member and the drum plate is obtained through the detection member. After the drum plate expands or contracts radially, the radius C2 of the drum plate is measured at this time, and the distance B2 between the detection member and the drum plate is obtained. The offset parameter of the detection member is calculated according to C1, C2, B1, and B2. In the execution process, the distance A2 between the detection member and the rotating shaft is obtained through the detection member. If A2 is the same as A1, the distance B3 between the detection member and the drum plate is obtained through the detection member. The radius C3 of the drum plate is calculated according to A2, B3 and the offset parameter, and C3 is compared with the predetermined radius C of the drum plate. If C3 is the same as C, the rubber starts to be wound on the drum plate and the tire production operation is carried out.

[0027] Specifically, in actual use, the distance between the detection piece and the rotating shaft is a fixed value A1. In order to facilitate the measurement of the distance between the detection piece and the rotating shaft and the distance between the detection piece and the drum plate, the detection piece usually uses a laser distance sensor. However, due to vibration during operation and other reasons, it is impossible to ensure that the light emitted by the laser distance sensor light source passes through the axis of the rotating shaft. Therefore, it is necessary to measure the deflection angle of the laser distance sensor to reduce the detection deviation. When the drum plate expands or contracts, the position of the light-transmitting hole on the drum plate will change, and the position of the light source of the laser distance sensor remains unchanged. The offset parameters of the detection piece are calculated by the distance B1 between the detection piece and the drum plate and the radius C1 of the drum plate measured before the trigonometric function changes and the distance B2 between the detection piece and the drum plate and the radius C2 of the drum plate after the change. After that, the tire is processed and tested. Before work, the distance A2 between the detection piece and the rotating shaft is detected. If A2 is the same as A1, the equipment is working normally. If A2 is different from A1, the operator needs to check and correct it. Afterwards, the distance B3 between the detection piece and the drum plate is obtained through the detection piece, and the radius C3 of the drum plate is calculated according to A2, B3 and the offset parameter, and C3 is compared with the predetermined radius C of the drum plate. If C3 is the same as C, the rubber starts to be wound on the drum plate and the tire production operation is carried out.

[0028] In this way, each tire drum diameter data can be detected and corrected, eliminating the need for operators to frequently check the drum diameter data, reducing equipment downtime for inspection, reducing the operator's workload, and improving tire production efficiency; avoiding the problem of loss of drum diameter accuracy due to the operator's inspection interval time period, thereby improving tire quality.

[0029] In the present application, the drum diameter detection method further includes: when the size of the tire to be processed changes, repeating the calibration process and the execution process; when the size of the tire to be processed remains unchanged, only repeating the execution process.

[0030] Specifically, in actual production, tires of different diameters are produced. When producing tires of the same diameter, the size of the drum plate does not change when it expands or contracts, so only one calibration is required. When the diameter of subsequent production remains unchanged, no calibration is required. When the diameter of the produced tire changes, the size of the drum plate expands or contracts, and in order to reduce measurement errors, the offset parameters of the detection component need to be re-acquired.

[0031] In the present application, the drum plate includes a transparent member, and the drum diameter detection method also includes that when the distance between the detection member and the rotating shaft is obtained through the detection member, the transparent member is aligned with the detection member, and the detection light of the detection member passes through the transparent member to reach the rotating shaft; when the distance between the detection member and the drum plate is obtained through the detection member, the transparent member and the detection member are misaligned, and the detection light of the detection member reaches the drum plate.

[0032] Specifically, by rotating the shaft, it is possible to adjust whether the transparent member, the detection member and the shaft are located on the same straight line. If they are located on the same straight line, the distance between the detection member and the shaft is detected; if they are not located on the same straight line, the distance between the detection member and the drum plate is detected. In this way, only one transparent member is required to detect two data, which is convenient for data detection.

[0033] In the present application, there are multiple transparent elements and each of them has a through hole, and the through holes of at least two transparent elements are of different sizes. The drum diameter detection method also includes an adjustment process before the calibration process, and the adjustment process includes: obtaining the required size of the through hole based on the required error size and the time for the detection element to align the through hole, and replacing the transparent element so that the size of the through hole of the replaced transparent element is the same as the size of the required through hole.

[0034] Specifically, when light passes through a small through hole, the light spot formed is smaller, so the measurement error will be smaller, but the alignment time between the detection part and the through hole will be increased; when light passes through a large through hole, the light spot formed is larger, so the measurement error will be larger, but the alignment time between the detection part and the through hole will be reduced. In actual use, according to the workers' operating experience and the tire diameter, the through hole of the appropriate size is selected to improve the detection accuracy as much as possible while improving production efficiency.

[0035] In the present application, the drum diameter detection method further includes if A2 is different from A1, or C3 is different from C, the alarm device sounds an alarm.

[0036] Specifically, by means of alarm, it is convenient to notify the operator and adjust the equipment in time.

[0037] In the present application, the detection member is adjustably arranged on the mounting bracket, and the drum diameter detection method also includes adjusting the position of the detection member on the mounting bracket when A2 is different from A1, or C3 is different from C, and repeating the calibration process or the execution process.

[0038] By changing the position of the detection member on the mounting bracket, the detection member can be easily adapted to tires of different sizes and diameters, or the detection member can be adjusted when A2 is different from A1, or C3 is different from C.

[0039] Embodiment 2

[0040] See also Figure 1 The drum diameter detection device includes a drum shaft, a drum plate assembly 20 and a detection member 30. The drum plate assembly 20 can be expanded and contractedly sleeved on the outside of the rotating shaft 10, and the rotating shaft 10 drives the drum plate assembly 20 to rotate together. The drum plate assembly 20 includes a plurality of drum plates arranged circumferentially and / or axially. The detection member 30 faces the drum plate assembly 20 and is used to detect the distance between the drum plate and the rotating shaft 10.

[0041] When in use, the detection member 30 is set at a fixed position. During detection, the distance between the detection member 30 and the drum plate and the rotating shaft 10 is detected and recorded through the detection member 30. During operation, the distance between the detection member 30 and the drum plate and the distance between the detection member 30 and the rotating shaft 10 are detected by the detection component. Each tire drum diameter data can be detected and corrected. There is no need for the operator to frequently check the drum diameter data, which reduces the equipment downtime detection time, reduces the operator's workload, and improves tire production efficiency.

[0042] Preferably, the detection member 30 is a laser distance measuring sensor, which can be used to conveniently detect the distance between the detection member 30 and the drum plate and the rotating shaft 10 .

[0043] In the present application, the drum plate includes a transparent member 40 for the detection light of the detection member 30 to pass through, and the detection member 30 detects the distance between itself and the rotating shaft 10 through the transparent member 40 .

[0044] In the present application, the transmissive member 40 has a transmissive structure for allowing the detection light of the detection member 30 to pass through, and the transmissive structure includes a transparent portion and / or a through hole.

[0045] Specifically, when the drum plate is in the contracted state, two adjacent drum plates are tightly fitted together, and light cannot pass through the drum plate at this time, so it is impossible to detect the distance between the detection member 30 and the rotating shaft 10. By arranging the transparent member 40 on the drum plate, it is convenient for light to pass through the drum plate and irradiate the rotating shaft 10, thereby facilitating the detection of the distance between the detection member 30 and the rotating shaft 10.

[0046] In the present application, the drum plate assembly 20 further includes a frame, and the drum plate is detachably mounted on the frame. There are multiple transparent members 40, and the sizes of the transparent structures of at least two transparent members 40 are different.

[0047] Specifically, when the light passes through a smaller transmission structure, the light spot formed is smaller, so the measurement error will be smaller, but the alignment time between the detection member 30 and the through hole will be increased; when the light passes through a larger transmission structure, the light spot formed is larger, so the measurement error will be larger, but the alignment time between the detection member 30 and the through hole will be reduced. In actual use, according to the operating experience of the workers and the diameter of the tire, a transmission structure of appropriate size is selected to improve the detection accuracy as much as possible while improving production efficiency.

[0048] In the present application, the drum diameter detection device further comprises a mounting bracket, and the detection member 30 is adjustably disposed on the mounting bracket.

[0049] By changing the position of the detection member 30 on the mounting bracket, the detection member 30 can be easily adapted to tires of different diameters.

[0050] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0051] 1. Specifically, in actual use, the distance between the detection piece and the rotating shaft is a fixed value A1. In order to facilitate the measurement of the distance between the detection piece and the rotating shaft and the distance between the detection piece and the drum plate, the detection piece usually uses a laser distance sensor. However, due to vibration during operation and other reasons, it is impossible to ensure that the light emitted by the laser distance sensor light source passes through the axis of the rotating shaft. Therefore, it is necessary to measure the deflection angle of the laser distance sensor to reduce the detection deviation. When the drum plate expands or contracts, the position of the light-transmitting hole on the drum plate will change, and the position of the light source of the laser distance sensor remains unchanged. The offset parameters of the detection piece are calculated by the distance B1 between the detection piece and the drum plate and the radius C1 of the drum plate measured before the trigonometric function changes and the distance B2 between the detection piece and the drum plate and the radius C2 of the drum plate after the change. After that, the tire is processed and tested. Before work, the distance A2 between the detection piece and the rotating shaft is detected. If A2 is the same as A1, the equipment is working normally. If A2 is different from A1, the operator needs to check and correct it. Afterwards, the distance B3 between the detection piece and the drum plate is obtained through the detection piece, and the radius C3 of the drum plate is calculated according to A2, B3 and the offset parameter, and C3 is compared with the predetermined radius C of the drum plate. If C3 is the same as C, the rubber starts to be wound on the drum plate and the tire production operation is carried out.

[0052] In this way, each tire drum diameter data can be detected and corrected, eliminating the need for operators to frequently check the drum diameter data, reducing equipment downtime for inspection, reducing the operator's workload, and improving tire production efficiency; avoiding the problem of loss of drum diameter accuracy due to the operator's inspection interval time period, thereby improving tire quality.

[0053] 2. When light passes through a small through hole, the light spot formed is smaller, so the measurement error will be smaller, but it will increase the alignment time between the detection part and the through hole; when light passes through a large through hole, the light spot formed is larger, so the measurement error will be larger, but it will reduce the alignment time between the detection part and the through hole. In actual use, according to the workers' operating experience and the tire diameter, choose the appropriate size of the through hole to improve the detection accuracy as much as possible while improving production efficiency.
