As shown in fig. 1 and 2, an embodiment of the present invention 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 a conveying device disclosed in chinese patent publication No. CN110039807A and comprises a first conveying assembly. The tire material conveying system refers to a conveying system from leading of tire materials to fitting between drum components.
During the process of conveying the tire material 10 to the drum component (not shown), the tire material 10 to be cut is first conveyed to the tire material conveying device 100, and then cut to length to form the tire components 10a for forming the tire assembly. Of course, before the tire material 10 is cut to length to cut the tire component 10a, the tire material 10 needs to be width tested for subsequent correction steps of the tire component 10a. Finally, the tire member 10a is attached to the drum member after the steps of correction, secondary length measurement, and the like.
It should be noted that, in the process of conveying the tire material 10, that is, in the process of moving the tire material 10, the tire material conveying device 100 provided by the present invention does not need to stop, and can detect and obtain the average value of the width in one lengthwise region of the tire material 10 in real time, and use the average value of the width as the basis for correcting the deviation of the tire component 10a. Because the width of this tire material 10 can reflect the actual width of tire material 10 basically to can realize the good effect of rectifying a deviation to tire component 10a, realize the effect that the head and the tail of tire component 10a can accurate laminating on drum parts. As shown in fig. 1 and 2, the tire material conveying device 100 is electrically connected to a control system (not shown) of the tire building machine, and includes a conveying frame 1, a guiding mechanism located at one end of the conveying frame 1, a supporting mechanism disposed below the guiding mechanism and connected to the conveying frame 1, a position detecting mechanism fixed below the conveying frame 1, and a width detecting mechanism located above the conveying frame 1. Wherein, carriage 1 is used for carrying tire material 10, and guiding mechanism is used for guiding tire material 10, and supporting mechanism is used for providing the support to guiding mechanism, and position detection mechanism can know guiding mechanism along the ascending concrete position of carriage 1 width direction, and width detection mechanism can obtain the width of tire material 10 in tire material 10 transportation process. The following describes the structure of the tire material conveying device 100 in detail.

Wherein the frame plate 11 supports the conveyor rolls 12, and a plurality of the conveyor rolls 12 can roll in the conveying direction for conveying the tire material 10.
As shown in fig. 2 and 3, the guiding mechanism includes two guiding frames 31, and the tire material 10 is conveyed between the two guiding frames 31. Further, the spacing between the two guide frames 31 is adjustable, so that it is possible to adapt to tire materials 10 of different widths. Since the central symmetry line of the two guiding frames 31 is consistent with the central line of the conveying frame 1, the two sides of the tire material 10 are limited by the guiding frames 31, and the center of the tire material 10 can be generally ensured to be on the central line of the conveying frame 1.
The guide mechanism further comprises a guide roller 32 arranged on the guide frame 31, the guide roller 32 is rotatably arranged on the guide frame 31, and the axis of the guide 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 to reduce frictional resistance of the tire material 10 during conveyance, facilitating smooth conveyance of the tire material 10.
It should be noted that the distance between the two guide frames 31 can be adjusted by an adjusting mechanism. As shown in fig. 3, the adjustment mechanism is provided on the carriage 1 below the conveyance roller 12. The adjusting mechanism comprises a screw rod 33 and an adjusting handle 34, and the adjusting handle 34 is fixedly connected with the screw rod 33, so that an operator can conveniently rotate the screw rod 33. Specifically, the screw 33 transversely passes through the conveying frame 1 and is rotatably supported on the conveying frame 1. At least two nuts are spaced on the screw 33, and each nut is provided with a connector (not shown) for connecting the guide frame 31.
Further, the screw rod 33 is provided with two thread sections with opposite thread directions, each thread section can be provided with a nut, and the screw rod 33 drives the two nuts to synchronously move oppositely or move oppositely along the axial direction when rotating, so that the two guide frames 31 are close to or far away from each other. The operator rotates the adjustment handle 34 to rotate the lead screw 33, and the distance between the two nuts can be adjusted by rotating the lead screw 33, so that the distance between the two guide frames 31 respectively connecting the two nuts can be adjusted.
As shown in fig. 3, the supporting mechanism includes a cross member 41 and a slider 42, and the cross member 41 is fixed to the frame plates 11 on both sides of the carriage 1 in the width direction of the carriage 1. The slide rail 410 is disposed on one side of the cross beam 41 facing the lead screw 33, the connecting piece on the nut is connected to the guide frame 31 and the sliding block 42, the two sliding blocks 42 are respectively butted with the corresponding nuts, and the sliding block 42 is in sliding fit with the slide rail 410.
As shown in fig. 3, the position detection mechanism includes a linear sensor 51 and a sensing member 52, and one of the linear sensor 51 and the sensing member 52 is fixed to the cross member 41 or the carriage 1, and the other is fixed to the guide frame 31. Specifically, the linear sensor 51 and the sensing member 52 may sense each other, the linear sensor 51 serves to detect an end surface, the initial position is located at the center line of the carriage 1, and when one of them moves, the other may sense the distance therebetween, so that the position detection mechanism may detect the distance of the guide 31 from the center line of the carriage 1.
In the present embodiment, as shown in fig. 3, the linear sensor 51 is fixed to the cross beam 41, and the sensing member 52 is fixed to one of the guide frames 31 by a fixing frame 53. The fixing frame 53 is perpendicular to the guide frame 31 and extends toward the cross beam 41 such that the sensing piece 52 fixed to the fixing frame 53 is opposite to a side of the linear sensor 51, so that the sensing piece 52 and the linear sensor 51 can sense each other. When the sensing member 52 moves relative to the linear sensor 51, the linear sensor 51 may sense a distance between the sensing member 52 and the linear sensor 51. Since one end of the linear sensor 51 for sensing is disposed at the center line of the carriage 1 and the symmetry line of the two guides 31, the linear sensor 51 can detect the moving distance of the guides 31 relative to the center line of the carriage 1 in real time through the sensing member 52.
Specifically, the linear sensor 51 is connected to a control system, and the control system can display the distance detected by the linear sensor 51 on a screen, whereby, when the operator rotates the adjustment handle 34 to adjust the distance between the two guide frames 31, the adjustment can be performed according to the data displayed on the screen until the data matches the value of one-half of 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 two guide frames 31, so that the distance between the two detection elements 21 can be changed along with the movement of the guide frame 31. The connecting line between the two detecting elements 21 is perpendicular to the guiding frame 31, and the position of the detecting element 21 is the detecting position. The detecting elements 21 detect both side edges of the tire material 10 during the conveyance of the tire material 10 to obtain the width of the tire material 10 in real time. Since the two detecting elements 21 detect only the side edges of the tire material 10, the space occupied by the detecting elements 21 is small.
Further, the detecting element 2 comprises a transmitter capable of emitting a row of light curtains 211 consisting of light rays, the center 212 of the light curtain of the detecting element 21 having been calibrated before the detection, the center 212 of the light curtain being located right at the side edge of the tyre material 10 to be cut, and a receiver capable of receiving the light curtain 211. The width of the tire material 10 can thus be calculated from the light intercepted by the light curtain 211 when the side edges are convex or concave. In particular, the detecting element 21 can detect the width in real time during the running process of the tire material 10 without stopping the detection, thereby improving the detection efficiency.
Alternatively, as shown in fig. 5, the width detection mechanism may further include two detection rollers 22, the length of the detection roller 22 is not less than the width of the tire material 10, the two detection rollers 22 are respectively located above and below the tire material 10, one detection roller 22 is used for emitting light, the other detection roller 22 is used for receiving light, and therefore the width of the tire material 10 may be calculated according to the blocked light.
As shown in fig. 6, in the longitudinal direction of the carriage 1, the position of the mechanism for cutting the tire material 10 and the position of the detecting element 21 are unchanged, and are set as the cutting position Q1 and the detecting position Q2, respectively, so that the distance L2 between the cutting position Q1 and the detecting position Q2 is unchanged, and L2 is known. A cutter (not shown) is provided above the cutting position, and can cut the tire material 10. The width detection mechanism is provided at the detection position Q2, and the length L1 of the tire component 10a cut out from the tire material 10 is known.
In the process of conveying the tire material 10, the width of the tire material 10 is detected in a set lengthwise area to obtain the width of the tire material 10, and the detected width is used as a deviation correction basis for the next tire component 10a to be cut. Preferably, the longitudinal area is the area to be cut, i.e. the cutting area, on the tyre material 10.
Since the width detection mechanism acquires the width in the cutting area of the tire material 10, the width is representative and can be used as a basis for correcting the deviation of the next tire component 10a.
Preferably, the width detection mechanism performs a plurality of width detections on the tire material 10 in the longitudinal region and obtains a plurality of width values, and the control system calculates an average value of the plurality of width values and stores 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 invention is L2, which is smaller than the length L1 of the tire component 10a. When one cut of tire material 10 is completed, the tire component 10a is conveyed forward while the remaining tire material 10 begins to be conveyed forward.
The width detection mechanism carries out width detection for a plurality of times on a section of lengthwise region of the tire material 10 in the conveying process of the tire material 10, the control system stores a plurality of width values detected by the width detection mechanism and calculates the average value of the plurality of width values, and the average value can be used as a reference value for subsequent deviation correction.
The embodiment of the invention also provides a tire material detection method, which comprises the following steps:
step one, tire materials 10 are conveyed on a conveying frame 1, when a cutting area of the tire materials 10 reaches a cutting position, the tire materials 10 are cut, and after the cutting is finished, a control system starts timing.
Specifically, the leading end of the tire material 10 shown at a in fig. 6 has been cut, and the carriage 1 will begin to convey the tire material 10 forward, and the control system may begin timing.
Step two, after the time is counted to the time length T1, the width detection mechanism detects the tire material 10, and the width D of the tire material 10 to be cut is obtained for multiple times along with the conveying of the tire material 10;
and step three, after the time is counted to the time length T2, the width detection mechanism stops detecting the width D of the tire material 10.
The starting time and the ending time of the width detection mechanism are controlled, so that the width of the tire material 10 in the longitudinal area where the tire material 10 to be cut is located is obtained, after N widths D are obtained, the control system calculates and stores the average value of the widths D, and the accuracy and the reliability of the width detection of the tire material are guaranteed. The tire material conveying device 100 can acquire the width of the tire material 10 in real time, and the width is used as a basis, so that the center of the tire component 10a is consistent with the center of the belt drum when the cut tire component 10a is corrected, and the position accuracy control of the tire material attaching on the belt drum is accurate.
T1 and T2 can be set according to actual conditions. After the time is counted to the time length T1, the width detection mechanism starts to detect, as shown in FIG. 6 at B; after the start of counting time to the time period T2, the width detection mechanism stops the detection, as shown in fig. 6 at C. The width detection mechanism is in the detection state for a period of time T1 to T2, and the distance that the tire material 10 is conveyed forward is the detection length of the width detection mechanism, which is the length of the cut region on the tire material 10.
As will be known to those skilled in the art, the tire component 10a obtained after cutting is a parallelogram, the angle of the triangular region thereof is known as γ, the preset width of the tire material 10 to be cut is D0, and the detection length of the width detection mechanism in the conveying direction of the tire material 10 to be cut is not less than L3, where L3= D0/tan γ.
Because tire component 10a is cut the back, need laminate on drum part, and the head and the tail both ends hypotenuse of tire component 10a need align, and L3 is just a section length of cutting region on tire material 10, consequently detects the width in L3 length range, more can guarantee that the position accuracy control of tire material laminating on the drum is accurate.
In the present embodiment, the speed at which the conveyor 1 conveys the tire material 10 is set to be V, the time period T1= (L1-L2-L3/2)/V, and the time period T2= (L1-L2 + L3/2)/V. That is, the detection is started when the front end of L3 reaches the detection element 21, and the detection is stopped when the rear end of L3 reaches the detection element 21.
Specifically, as shown in fig. 6 a, when the to-be-cut portion of the tire material 10 reaches the cutting position Q1, one cutting is completed, and the center of the front end of the tire material 10 is located at the cutting position Q1, and since the length L1 of the tire member 10a is set, L1 is known, and the distance L2 between the cutting position Q1 and the detection position Q2 is known, and the front end of L3 has not yet reached the detection position Q2, and the tire material 10 is conveyed further.
As shown in B in fig. 6, after the tire material 10 is conveyed for a time period T1, the center of the front end of L3 reaches the detection position Q2, the detection by the detection element 21 starts, during which the tire material 10 is still conveyed, and the detection result is obtained by the detection element 21 a plurality of times.
After the tire material 10 is conveyed for a time period T2 as shown in fig. 6C, the center of the rear end of L3 reaches the detection position Q2, the detection by the detection element 21 is stopped, and the tire material 10 is still conveyed forward.
In summary, the tire material conveying device and the tire material detecting method provided by the invention can detect and obtain the average value of the width in one lengthwise region of the tire material in real time, and use the average value of the width as the basis for deviation correction of the tire component. Because the actual width of this tire material can reflect the tire material basically to can realize the good effect of rectifying a deviation to tire component, realize the effect that the head and the tail of tire component on drum part can accurate laminating.

step two, after timing is started to reach a time length T1, continuously detecting one lengthwise region of the conveyed tire material by a width detection mechanism to obtain a plurality of widths D of the tire material;
in the second step, the angle of the tire material to be cut is gamma, the preset width of the tire material is D0, and the detection length of the width detection mechanism is not less than L3 along the conveying direction of the tire material, wherein L3= D0/tan gamma;
the method comprises the following steps that a row of light curtains formed by light rays are emitted by a transmitter, a receiver receives the light curtains, when the side edge protrudes or is recessed, the width of the tire material is calculated according to the light rays blocked by the light curtains, and the longitudinal area is an area to be cut on the tire material;
and step three, after the time is counted to the time length T2, the width detection mechanism stops detecting the width of the tire material.
8. The tire material testing method of claim 7, further comprising the step four of:
the control system calculates an average of a plurality of the widths D and stores the average.
9. The tire material detection method according to claim 7, wherein the speed at which the conveyor frame conveys the tire material is V, the distance between the cutting position and the detection position at which the width detection mechanism is located is L2, and the length of the tire component obtained after the tire material is cut is set to L1, a time period T1= (L1-L2-L3/2)/V, and a time period T2= (L1-L2 + L3/2)/V.
