Background technique

Chinese Patent Application Publication No. CN110039807A discloses a device and method for centering tire material. This patent application discloses a first conveying assembly and a second conveying assembly for conveying tire materials, and a first detection mechanism disposed on the first conveying assembly. When the tire material is located on the first conveying component, but the front end has not been conveyed to the second conveying component, the first detection mechanism can obtain the width of a certain longitudinal position on the tire material, and use this width as the basis for the subsequent tire material. Corrected reference data. In this way, the technical solution disclosed in this patent application can satisfy the rectification and centering of tire materials of different widths under the same specification.

However, the width of the tire material acquired by the first detection mechanism is only the width of a certain longitudinal position of the tire material, and the width value is a single value. Since both sides of the tire material are not flush, and the tire material is long, the single width value obtained by the detection mechanism at a certain position cannot represent the overall width of the tire material. Therefore, after using a single width value as the reference basis for the deviation correction of the tire material, when the tire material is attached to the drum component, the result of the tire material's end-to-end lamination accuracy and quality is relatively poor.

In addition, when the first detection mechanism measures the width of a certain longitudinal position of the tire material, it is necessary to suspend the transportation of the tire material, which also leads to a decrease in the tire building efficiency.

Therefore, it is necessary to provide a tire material conveying device and a tire material detection method to solve the above problems.

As shown in FIG. 1 and FIG. 2 , an embodiment of the present application provides a tire material conveying device 100 . The tire material conveying device 100 is a part of a tire material conveying system of a tire building machine, and basically corresponds to the first conveying assembly disclosed in Chinese Patent Application Publication No. CN110039807A. The above-mentioned tire material conveying system refers to the conveying system from the uncoiling of the tire material to the fitting to the drum member.

In the process of conveying the tire material 10 to the drum part (not shown), the tire material 10 to be cut is firstly conveyed to the tire material conveying device 100, and after being cut to length, the tire components for forming tires are formed one by one. the tire component 10a. Of course, before the tire material 10 is cut to length and the tire component 10a is cut to a certain length, the tire material 10 needs to be subjected to width detection for the subsequent deviation correction step of the tire component 10a. Finally, the tire component 10a is attached to the drum component after undergoing steps such as deviation correction and secondary length measurement.

It should be noted that the tire material conveying device 100 provided in the present application can detect and acquire a longitudinal length of the tire material 10 in real time without stopping during the process of conveying the tire material 10, that is, during the traveling process of the tire material 10. The average value of the width in the area is used as the basis for the deviation correction of the tire component 10a. Since the width of the tire material 10 can basically reflect the actual width of the tire material 10, a good deviation correction effect can be achieved for the tire component 10a, and the effect of accurately fitting the tire component 10a on the drum component can be achieved. As shown in FIG. 1 and FIG. 2 , the tire material conveying device 100 is electrically connected to the control system (not shown) of the tire building machine, and includes a conveying frame 1 , a guiding mechanism at one end of the conveying frame 1 , and a guide mechanism disposed below the guiding mechanism. A support mechanism connected with the conveying frame 1 , a position detection mechanism fixed under the conveying frame 1 and a width detection mechanism located above the conveying frame 1 . The conveyor frame 1 is used for conveying the tire material 10 , the guide mechanism is used to guide the tire material 10 , the support mechanism is used to provide support for the guide mechanism, and the position detection mechanism can know that the guide mechanism is along the width direction of the conveyor frame 1 . The width detection mechanism can obtain the width of the tire material 10 during the conveying process of the tire material 10 . The structure of the tire material conveying device 100 will be described in detail below.

As shown in FIG. 1 , the conveying frame 1 includes two frame plates 11 arranged at a lateral interval and a plurality of parallel conveying rollers 12 arranged between the frame plates 11 . The frame plate 11 supports the conveying rollers 12 , and the plurality of conveying rollers 12 can roll in the conveying direction for conveying the tire material 10 .

As shown in FIG. 2 and FIG. 3 , the guide mechanism includes two guide frames 31 , and the tire material 10 is conveyed between the two guide frames 31 . The distance between the two guide frames 31 is adjustable so as to be able to adapt to tire materials 10 of different widths. Since the center line of symmetry of the two guide frames 31 is consistent with the center line of the conveying frame 1 , the two sides of the tire material 10 are restricted by the guide frames 31 to generally ensure that the center of the tire material 10 is on the center line of the conveying frame 1 . .

The guiding mechanism further includes a guiding roller 32 arranged on the guiding frame 31 , the guiding roller 32 is rotatably arranged on the guiding frame 31 , and the axis of the guiding roller 32 is perpendicular to the feeding plane of the conveying frame 1 . Both sides of the tire material 10 are in contact with the guide rollers 32 , so as to reduce the frictional resistance of the tire material 10 during the conveying process, so as to facilitate the smooth conveying of the tire material 10 .

It should be noted that the distance between the two guide frames 31 can be adjusted by an adjustment mechanism. As shown in FIG. 3 , the adjusting mechanism is arranged on the conveying frame 1 and is located below the conveying roller 12 . The adjustment mechanism includes a screw rod 33 and an adjustment handle 34 , and the adjustment handle 34 is fixedly connected with the screw rod 33 to facilitate the operator to rotate the screw rod 33 . Specifically, the screw rod 33 transversely passes through the conveying frame 1 and is rotatably supported on the conveying frame 1 . At least two nuts are arranged on the screw rod 33 at intervals, and each nut is provided with a connecting piece (not shown) for connecting the guide frame 31 .

The screw rod 33 has two thread segments with opposite thread directions, and each thread segment can be respectively provided with a nut. When the screw rod 33 rotates, it drives the two nuts to move synchronously relative to or opposite to each other in the axial direction, thereby realizing two guide frames. 31 are close or far away. The operator rotates the adjustment handle 34 to rotate the screw rod 33, and the rotation of the screw rod 33 can adjust the distance between the two nuts, so that the distance between the two guide frames 31 respectively connecting the two nuts can be adjusted.

As shown in FIG. 3 , the support mechanism includes a cross beam 41 and a slider 42 , and the cross beam 41 is fixed on the two side frame plates 11 of the conveying frame 1 along the width direction of the conveying frame 1 . Among them, the side of the beam 41 facing the screw rod 33 is provided with a slide rail 410. The connecting piece on the nut not only connects the guide frame 31 but also connects the slider 42. The two sliders 42 are respectively connected to the corresponding nuts. Rail 410 is a sliding fit.

As shown in FIG. 3 , the position detection mechanism includes a linear sensor 51 and a sensing member 52 . One of the linear sensor 51 and the sensing member 52 is fixed on the beam 41 or the conveying frame 1 , and the other is fixed on the guide frame 31 . Specifically, the linear sensor 51 and the sensing element 52 can sense each other. The linear sensor 51 is used to detect one end face, and the initial position is located at the center line of the conveying frame 1. When one of them moves, the other can sense the distance between the two. Therefore, the position detection mechanism can detect the distance between the guide frame 31 and the center line of the conveying frame 1 .

In this embodiment, as shown in FIG. 3 , the linear sensor 51 is fixed on the beam 41 , and the sensing element 52 is fixed on one of the guide frames 31 through a fixing frame 53 . The fixing frame 53 is perpendicular to the guiding frame 31 and extends toward the beam 41 , so that the sensing element 52 fixed to the fixing frame 53 is opposite to one side of the linear sensor 51 , so that the sensing element 52 and the linear sensor 51 can sense each other. When the sensing element 52 moves relative to the linear sensor 51 , the linear sensor 51 can sense the distance between the sensing element 52 and the linear sensor 51 . Since the end of the linear sensor 51 for sensing is set at the center line of the conveying frame 1 and the symmetry lines of the two guide frames 31 , the linear sensor 51 can detect the position of the guide frame 31 relative to the conveying frame 1 in real time through the sensing element 52 . The distance to move the centerline.

Specifically, the linear sensor 51 is connected to the control system, and the control system can display the distance detected by the linear sensor 51 on the screen. The adjustment is made according to the data displayed on the display screen until the data matches the value of one-half the width of the tire material 10 of the preset specification.

As shown in FIG. 4 , the width detection mechanism includes two detection elements 21 arranged at intervals, and the two detection elements 21 are respectively fixed on the two guide frames 31, so the distance between the two detection elements 21 can be adjusted according to the guide frame. 31 moves and changes. The connecting line between the two detection elements 21 is perpendicular to the guide frame 31, and the position of the detection element 21 is the detection position. During the conveying process of the tire material 10 , the detection element 21 detects the two side edges of the tire material 10 to obtain the width of the tire material 10 in real time. Since the two detection elements 21 only detect the side edges of the tire material 10, the space occupied by the detection elements 21 is small.

The detection element 2 includes a transmitter and a receiver. The transmitter can emit a row of light curtains 211 composed of light. Before detection, the light curtain center 212 of the detection element 21 has been calibrated, and the light curtain center 212 is just located in the tire material to be cut. 10, the receiver is able to receive the light curtain 211. Therefore, when the side edge is convex or concave, the width of the tire material 10 can be calculated according to the light blocked by the light curtain 211 . In particular, the detection element 21 can detect the width in real time during the running process of the tire material 10 without stopping for detection, which improves the detection efficiency.

Optionally, as shown in FIG. 5 , the width detection mechanism may also include two detection rollers 22 , the length of the detection rollers 22 is not less than the width of the tire material 10 , and the two detection rollers 22 are located above and below the tire material 10 respectively. , one detection roller 22 is used for emitting light, and the other detection roller 22 is used for receiving light, so the width of the tire material 10 can be calculated according to the blocked light.

As shown in FIG. 6 , in the length direction of the conveying frame 1 , the position of the mechanism for cutting the tire material 10 and the position of the detection element 21 remain unchanged, and are correspondingly set as the cutting position Q1 and the detection position Q2, so the cutting position Q1 The distance L2 from the detection position Q2 is constant, and L2 is known. A cutter (not shown) is provided above the cutting position, which can cut the tire material 10 . The width detection mechanism is set at the detection position Q2, and the length L1 of the tire component 10a cut from the tire material 10 is known.

During the conveying process of the tire material 10, the width is detected in a set longitudinal area of the tire material 10 to obtain the width of the tire material 10, which is used as the deviation correction basis for the next tire component 10a to be cut. The above-mentioned longitudinal area is the area on the tire material 10 to be cut, ie, the cutting area.

Since the width detection mechanism acquires the width within the cutting area on the tire material 10, this width is representative and can be used as the basis for the deviation correction of the next tire component 10a.

The width detection mechanism performs multiple width detections on the tire material 10 in the longitudinal area, and obtains multiple width values. The control system calculates the average value of the multiple width values, and saves the average value of the width values.

In this embodiment, the distance between the cutting position Q1 and the detection position Q2 of the tire material conveying device 100 provided by the present application is L2, which is smaller than the length L1 of the tire component 10a. When one cutting of the tire material 10 is completed, while the tire component 10a is transported forward, the remaining tire material 10 also begins to be transported forward.

During the conveying process of the tire material 10, the width detection mechanism performs multiple width detections on a longitudinal area of the tire material 10. The control system saves the multiple width values detected by the width detection mechanism, and calculates the average value of the multiple width values. The average value can be used as the reference value for subsequent deviation correction.

The embodiment of the present application also provides a tire material detection method, comprising:

Step 1. The tire material 10 is conveyed on the conveyor 1. When the cutting area of the tire material 10 reaches the cutting position, the tire material 10 is cut. After the cutting is completed, the control system starts timing.

Specifically, the front end of the tire material 10 shown at A in FIG. 6 has been cut. At this time, the conveyor 1 is about to start to transport the tire material 10 forward, and the control system can start timing.

Step 2: After the timing starts to time T1, the width detection mechanism detects the tire material 10, and obtains the width D of the tire material 10 to be cut multiple times as the tire material 10 is conveyed.

Step 3: After the timing starts to time T2, the width detection mechanism stops detecting the width D of the tire material 10 .

By controlling the start time and end time of the width detection mechanism, the width of the tire material 10 in the longitudinal area where the tire material 10 to be cut is located is obtained, and after N widths D are obtained, the control system calculates the average value of the width D and stores it , to ensure the accuracy and reliability of tire material width detection. Since the tire material conveying device 100 can obtain the width of the tire material 10 in real time, and use this width as a basis, when rectifying the cut tire component 10a, the center of the tire component 10a and the center of the belt drum are kept in the same position. In order to make the positional precision of the tire material fit on the belt drum accurately controlled.

T1 and T2 can be set according to the actual situation. After starting the timing to the duration T1, the width detection mechanism starts to detect, as shown at B in Figure 6; after starting the timing to the duration T2, the width detection mechanism stops detection, as shown at C in Figure 6. During the period from T1 to T2, the width detection mechanism is always in the detection state, and during this period of time, the distance that the tire material 10 is transported forward is the detection length of the width detection mechanism, and the detection length is the cutting area on the tire material 10 length.

Those skilled in the art can know that the tire component 10a obtained after cutting is a parallelogram, the angle of its triangular area is known as γ, the preset width of the tire material 10 to be cut is D0, and the width of the tire material 10 to be cut is D0. In the conveying direction of the material 10, the detection length of the width detection mechanism is not less than L3, where L3=D0/tanγ.

After the tire part 10a is cut, it needs to be attached to the drum part, and the oblique edges at both ends of the tire part 10a need to be aligned, and L3 is a length of the cutting area on the tire material 10, so the length range of L3 The inner width is detected, which can ensure the accurate control of the position accuracy of the tire material on the drum.

In this embodiment, the speed at which the conveying frame 1 conveys the tire material 10 is known as V, the duration T1=(L1-L2-L3/2)/V, and the duration T2=(L1-L2+L3/2)/ V. That is, the detection starts when the front end of L3 reaches the detection element 21 , and the detection stops when the rear end of L3 reaches the detection element 21 .

Specifically, as shown in A in FIG. 6 , when the part to be cut of the tire material 10 reaches the cutting position Q1, one cutting is completed. At this time, the center of the front end of the tire material 10 is located at the cutting position Q1. Due to the length of the tire part 10a L1 has been set, so L1 is known, and the distance L2 between the cutting position Q1 and the detection position Q2 is known. At this time, the front end of L3 has not reached the detection position Q2, and the tire material 10 continues to be conveyed.

As shown in B in FIG. 6 , after the tire material 10 is conveyed for a length of time T1, the center of the front end of L3 reaches the detection position Q2, and the detection element 21 starts to detect. During this process, the tire material 10 is still being conveyed, and the detection element 21 obtains multiple times Test results.

As shown in C in FIG. 6 , after the tire material 10 is conveyed for a length of time T2, the center of the rear end of L3 reaches the detection position Q2, the detection element 21 stops detecting, and the tire material 10 is still conveyed forward.

To sum up, the tire material conveying device and the tire material detection method provided by the present application can detect and obtain the average value of the width in a longitudinal area of the tire material in real time, and use the average value of the width as the deviation correction of the tire components. in accordance with. Since the width of the tire material can basically reflect the actual width of the tire material, it can achieve a good effect of correcting the deviation of the tire component, and achieve the effect that the end of the tire component can be accurately fitted on the drum component.
