Description
Technical Field
The invention relates to the technical field of tire molding, in particular to a device and a method for centering a tire component.
Background
A tire building machine generally comprises a transfer device for transferring a tire component, such as a belt, to a drum, such as a belt drum, wherein the transfer device comprises a first transfer assembly and a second transfer assembly. During the transportation of the tire component from the first transportation assembly toward the second transportation assembly, a deviation rectification mechanism is needed to rectify the tire component so that the lateral center of the tire component is aligned with the lateral center of the second transportation assembly. At this point, the drum is moved laterally in front of the second conveyor assembly and the lateral center of the drum is aligned with the lateral center of the second conveyor assembly. In this case, the second transfer assembly can transfer the tyre components onto the drum and form them on the belt drum into a cylindrical shape with precise and regular positions.
U.S. patent publication No. US6,994,140B2 discloses a deviation correcting mechanism that corrects a tire component by detecting a tire component having a predetermined width. When the edges of the tire component are all moved forward along the guide locations, the center of the tire component is aligned with the center of the second conveyor assembly and the drum. However, if the actual width of the tire component is greater or less than the predetermined width, the center of the tire component may not be aligned with the center of the second conveyor assembly and the drum if the edge of the tire component still moves forward along the guide position, eventually resulting in a failure of the tire component to fit precisely onto the drum.
To solve the above problems, chinese patent publication No. CN105682912B discloses a method for centering a tire component, which is capable of centering tire components of various widths. The deviation correcting mechanism detects the side edge of the tire component, aligns the side edge to a preset guiding position on the second conveying assembly and conveys the tire component forwards. And after the front section part of the tire component enters the second conveying assembly, detecting the actual width of the tire component, and when the actual width is different from the preset width, deviating the actual center of the tire component from the center position on the second conveying assembly. Finally, the drum is moved, so that the center of the drum is aligned with the actual center of the tire component, and the tire component can be accurately attached to the forming drum. However, this movement of the first transport assembly and drum required for centering the tire component affects the stability of the centering of the tire component, while also increasing the difficulty of controlling the deviation correction mechanism. In addition, because the central position of the second conveying assembly is usually provided with the fixed-length detection mechanism, if the actual center of the tire component is different from the central position of the fixed-length detection mechanism, the fixed-length detection of the tire component is inaccurate, and the accuracy of splicing the joints of the tire component is affected.
In view of the above, there is a need for an improved apparatus and method for centering tire components to address the above-mentioned problems.

As shown in fig. 1-3, the present invention discloses an apparatus 100 for centering a tire component for use with a tire building machine. Specifically, the device 100 for centering a tire component includes a first conveying assembly 1, a second conveying assembly 2 adjacent to the first conveying assembly 1, a first detecting mechanism 3 disposed below the first conveying assembly 1, a second detecting mechanism 4 disposed between the first conveying assembly 1 and the second conveying assembly 2, a deviation-correcting driving mechanism 8 for correcting the deviation of the first conveying assembly 1, a fixed-length detecting mechanism 5 disposed on the second conveying assembly 2, a drum component 6 disposed downstream of the second conveying assembly 2, a tire component cutting device 7 disposed above the first conveying assembly 1, and a control module. The first detection mechanism 3, the second detection mechanism 4, the fixed length detection mechanism 5 and the deviation correction driving mechanism 8 are electrically connected with the control module respectively.
The apparatus 100 for centering tire components can ensure that the lateral center of the tire component 200 on the second conveyor assembly 2 is aligned with the lateral center of the drum component 6, so that the tire component 200 can be conveyed to a desired position on the drum component 6 and formed into a cylindrical shape on the drum component 6. In the present embodiment, the tire member 200 is a belt layer, and the drum member 6 is a belt drum. Of course in other embodiments the tire component may be other tire components, such as a ply.
As shown in fig. 1 and 7 to 10, in the present embodiment, the tire component 200 has a parallelogram shape, and includes a front end portion 210, a rear end portion 230, and a main portion 220 located between the front end portion 210 and the rear end portion 230, wherein the front end portion 210 and the rear end portion 230 are both triangular, and the main portion 220 is rectangular. The lateral direction is a direction perpendicular to the conveying direction F of the first conveying assembly 1 and/or the second conveying assembly 2, and the lateral direction is a width direction of the first conveying assembly 1 and the second conveying assembly 2. As shown in fig. 8-10, the first lateral center 260 of the tire component 200 is a straight line half the lateral width at the transition between the front end portion 210 and the main portion 220.
As shown in fig. 1 to 2 and 7 to 10, the apparatus 100 for centering a tire component further includes a support frame 11 supporting the first and second conveyor assemblies 1 and 2. The first conveyor assembly 1 receives the tire component 200 and is used to convey the tire component 200 towards the second conveyor assembly 2. The second conveyor assembly 2 is used for conveying the tyre component 200 towards the drum component 6. A spacing groove 13 is arranged between the first conveying assembly 1 and the second conveying assembly 2, and the first conveying assembly 1 conveys the tire component 200 to the second conveying assembly 2 through the spacing groove 13. In the present embodiment, the first conveying assembly 1 is a roller conveyor, the first conveying assembly 1 includes two side plates 14 vertically arranged and a plurality of conveying rollers 17 arranged between the two side plates 14 and spaced apart in the conveying direction, and a through hole 171 is provided between two adjacent conveying rollers 17. The second conveyor assembly 2 has a second lateral center 16, the second lateral center 16 being located at about half the lateral width of the second conveyor assembly 2. In the present embodiment, the second conveyor assembly 2 is a conveyor belt assembly.
As shown in fig. 1 to 2, 3 to 4, and 6, the first detection mechanism 3 is disposed below the first conveying assembly 1. The first detection mechanism 3 comprises a driving assembly arranged below the first conveying assembly 1 and a detection element 31 capable of moving transversely under the driving of the driving assembly, the driving assembly comprises a driving source 33, a lead screw 32 connected with the output end of the driving source and a second encoder electrically connected with the driving source, and the detection element 31 is arranged on the lead screw 32 in a matching and rotating mode. The detection element 31 is driven by the drive source to scan both side edges of the tire component 200 in a lateral movement to determine the actual width D of the tire component 200 at the first longitudinal position in the longitudinal direction. The first longitudinal position mentioned above is a position close to the front end portion 210 of the tyre component 200, i.e. at the transition or abutment between the front end portion 210 and the main portion 220 of the tyre component 200. The front end portion 210 can drive the screw 32 to rotate under the trigger of the second encoder at equal time intervals to drive the detection element 31 to move for detection. The detection element 31 is preferably a proximity switch and is arranged below the through-opening between two adjacently arranged transport rollers 17, so that the full width of the tire component 200 can be detected. After the first detection means 3 has detected the actual width D of the tyre component 200 at the first longitudinal position, the control module calculates the edge reference line 18 of the front portion 210 of the tyre component 200 on the second conveyor assembly 2 on the basis of the second transverse centre 16 and the actual width D of the tyre component 200 at the first longitudinal position.
In another embodiment, in order to ensure real-time performance, the first detection mechanism 3 includes an optical detection element fixedly disposed below the first conveyor assembly 1 and configured to detect the width of the tire component 200. The optical detection element may be a CCD camera, an infrared sensor, or the like, and is not particularly limited as long as it is an existing optical element capable of acquiring the actual width D of the tire member 200, and the optical detection element is included in the range of the optical detection element.
As shown in fig. 1 to 2 and 6 to 10, the second detecting mechanism 4 includes an upper image capturing element 41 disposed on the spacing slot 13, a light source generating element 42 disposed on the lower side of the spacing slot 13 and opposite to the image capturing element 41, a first encoder (not shown) connected to the image capturing element 41, and a controller 43 electrically connected to the control module. The image capturing element 41 cooperates with the light source generating element 42 for detecting the contour or lateral position of the leading end portion 210 of the tire component 200 at the position of the detection line 131 after entering the spacing slot 13. Here, the detection line 131 is an area detectable by the image pickup element 41. In the present embodiment, the image pickup element 41 is disposed above the spacing groove 13, and the light source generating element 42 is disposed below the spacing groove 13. In another embodiment, the image capturing element 41 may be disposed below the spacing slot 13, and the light source generating element 42 may be disposed above the spacing slot 13. The image pickup element 41 is a CCD camera. When the tire component 200 is in the process of being conveyed, i.e., the front end portion 210 of the tire component 20 moves above the spacing groove 13, the first encoder drives the image pickup element 41 to perform a plurality of detections in a pulse equal interval triggered manner, and transmits the detected image information to the controller 43, and the controller 43 processes the image information to obtain lateral position information of the actual lateral edge 250 of the tire component 200 and transmits the lateral position information to the control module.
As shown in fig. 1 to 2 and 5, after the image capturing device 41 detects the lateral position of the actual side edge 250 of the front end portion 210 of the tire component 200, the control module calculates the lateral offset T of the actual side edge 250 from the edge reference line 18, and then controls the deviation correcting driving mechanism 8 to drive the first conveying assembly 1 to move transversely, so that the actual side edge 250 of the tire component 200 is aligned with the edge reference line 18. It should be noted that, when the actual side edge 250 of the front end portion 210 of the tire component 200 moves into the detection range of the image capturing element 41, the image capturing element 41 captures the lateral position of the actual side edge 250 of the front end portion 210 of the tire component 200, and the control module calculates the lateral offset T, the control module controls the deviation rectifying driving mechanism 8 to drive the first conveying assembly 1 to move transversely. In addition, the image pickup element 41 may pick up the center position of the main portion 220 of the tire component 200 in real time during the forward conveyance of the tire component 200.
Here, the transverse movement of the first conveying assembly 1 means that the first conveying assembly 1 moves transversely, that is, a deviation correcting driving mechanism (not shown) drives the first conveying assembly 1 to translate transversely as a whole. In fig. 3 to 5, another mode of realizing the transverse movement is disclosed, and the transverse movement of the first conveying assembly 1 is that one end of the first conveying assembly 1 close to the second conveying assembly 2 rotates around a horizontal pivot shaft at the other end. Specifically, the deviation rectifying driving mechanism 8 comprises an electric cylinder 81 arranged at one end of the first conveying assembly 1 close to the second conveying assembly 2. The electric cylinder 81 includes a cylinder base and an expansion link, one end of which is connected to the first conveying assembly 1. The cylinder base is arranged on a support plate 15, and the support plate 15 is fixed on the top of the support frame 11. The conveyor roller 17 is arranged on the support frame 11 at an end remote from the second conveyor assembly 2 in a pivotable manner. When the electric cylinder 81 drives the telescopic rod to extend or contract, one end of the first conveying assembly 1 is driven to swing around the other end. As shown in fig. 1 to 2 and 7, the fixed-length detecting mechanism 5 includes a sensor 51 disposed on the second conveying member 2 at the second transverse center 16, and a distance S2 between the sensor 51 and the cutting device 7 is known. The sensor 51 is electrically connected with the control module, when the front edge of the tire component 200 contacts the sensor 51, the sensor 51 is triggered and starts to count time, the control module acquires the distance S1 traveled by the tire component 200 according to the conveying speed of the second conveying assembly 2 and the time counted by the sensor 51, and the sum of S1 and S2 is the length required by the tire component attached to the drum component 6.
As shown in fig. 7 to 10, the drum member 6 has a third transverse center 61, and the third transverse center 61 is a central plane of half the axial width of the outer circumferential surface of the drum member 6. In the working position, the third transverse center 61 of the drum member 6 is aligned with the second transverse center 16.
The device for centering the tire component of the invention can measure the actual width D of the first longitudinal position of the tire component 200 in real time by arranging the first detection mechanism 3 below the first conveying assembly 1, the control module calculates the edge reference line 18 of the front end part 210 of the tire component 200 on the second conveying assembly 2 according to the actual width D and the second transverse center 16 of the second conveying assembly 2, then the second detection mechanism 4 detects the actual side edge 250 of the front end part 210 of the tire component 200 in real time, the control module calculates the transverse offset T between the actual side edge 250 and the edge reference line 18, finally the control module controls the deviation correction driving mechanism 8 to drive the first conveying assembly 1 to transversely move according to the transverse offset T, so that the actual side edge 250 of the tire component 200 is aligned with the edge reference line 18, and the first transverse center 260 of the tire component 200 conveyed to the second conveying assembly 2 is ensured to be aligned with the transverse center 61 of the drum component 6, the quality of the splice of the tire component 200 on the drum component 6 is improved. In the manufacturing process of the tire components, due to various reasons, the width of the tire components with the same specification is different, so that the centering of the tire components is difficult.
As shown in fig. 7 to 10, the present invention also discloses a method for centering a tyre component using the above-described device 100, comprising the steps of:
the method comprises the following steps: when the tire component 200 is conveyed on the first conveyor assembly 1 without the leading end exceeding the first conveyor assembly 2, the first detection mechanism 3 acquires the actual width D of the tire component 200 at the first longitudinal position.
The specific process of the first detection mechanism 3 detecting the actual width D of the tire component 200 is as follows: the driving source 33 rotates by driving the lead screw 32, so that the detecting element 31 moves along the transverse direction of the first conveyor assembly 1 to scan both lateral edges 251 of the main portion 220 of the detecting tire component 200 near the boundary of the front end portion 210 to determine the actual width D of the tire component 200. That is, the first sensing mechanism 3 may obtain the actual width D of the first longitudinal location on the tire component 200.
Step two: the control module determines a side edge reference line 18 of the tire component 200 on the second conveyor assembly 2 based on the actual width D of the tire component 200 and the second lateral center 16 on the second conveyor assembly 2.
Step three: before the first conveying assembly 1 conveys the tire component 200 to the second conveying assembly 2, the second detecting mechanism 4 detects the transverse position of the actual side edge 250 of the front end part 210 of the tire component 200, the control module calculates the transverse offset T of the actual side edge 250 and the side edge reference line 18, the control module sends a signal to the deviation correcting driving mechanism 8 according to the received transverse offset T, and the deviation correcting driving mechanism 8 controls the first conveying assembly 1 to transversely move according to the transverse offset T so that the actual side edge 250 is aligned with the side edge reference line 18. In this manner, the first lateral center 260 is ensured to be aligned with the second lateral center 16, thereby completing centering of the front end portion 210 portion of the tire component 200. Before the tire component 200 is transferred onto the second transfer assembly 2 means that the front end portion 210 of the tire component 200 has been moved into the spacing groove 13.
Step four: when the main portion 220 of the tire member 200 is conveyed to the inspection line 131 at the spacing groove 13, the second inspection mechanism 4 can detect the lateral center of the main portion 220 of the tire member in real time, which may be referred to as a fourth lateral center. The second detection mechanism 4 acquires a real-time fourth transverse center of the main portion 220 of the tire component and sends the real-time fourth transverse center to the control module, the control module calculates a transverse offset according to the fourth transverse center and the second transverse center 16, and the control module controls the first conveying assembly 1 to transversely move according to the transverse offset so as to align the fourth transverse center of the main portion 220 of the tire component 200 with the second transverse center 16, and therefore centering of the main portion 220 of the tire component 200 is completed. In the process that the main part 220 is conveyed to the second conveying assembly 2, the second detection mechanism 4 detects the transverse center of the main part 220 in real time, and the control module can acquire the real-time transverse offset of the main part 220, so that the control module performs real-time centering according to the transverse offset.
When the tire component 200 is continuously conveyed towards the second conveyor assembly 2, after the tail end part 230 partially enters the spacing groove 13, the second detection mechanism 4 detects the transverse center of the junction of the intermediate component 220 and the tail end part 230 and sends the transverse center to the control module, the control module calculates the transverse offset according to the transverse center and the second transverse center 16, the control module controls the transverse movement of the second conveyor assembly 1 according to the transverse offset, and the transverse center of the junction of the intermediate component 220 and the tail end part 230 is aligned with the second transverse center 16, so that the centering of the tail end 230 is completed.
Step five: after the fixed length detecting mechanism 5 determines the tire component 200 of the required length, the cutting device 7 cuts the tire component 200 of the required length wound with a single tire blank. The desired length here means the length of the sum of the above-mentioned S1 and S2.
Step six: the second conveyor assembly 2 conveys the tire component 200 onto the drum component 6 and forms it into a cylindrical shape.
The method for centering the tire component comprises the steps that before the tire component 200 enters the second conveying assembly 2, the actual width D of the first longitudinal position of the tire component 200 is detected, the control module calculates the edge reference line 18 of the front end part 210 of the tire component 200 on the second conveying assembly 2 according to the actual width D, then the second detecting mechanism 4 detects the actual side edge 250 of the front end part of the tire component in real time, the control module calculates the transverse offset T between the side edge 250 and the edge reference line 18, and the deviation correcting driving mechanism 8 drives the first conveying assembly 1 to transversely move so that the actual side edge 250 of the tire component 200 is aligned with the edge reference line 18. Compared with the prior art, the method and the device for centering the tire component provided by the invention have the advantages that the width of the first longitudinal position of the tire component is obtained in advance, so that the deviation correction and centering of the tire components with different widths under the same specification can be realized. Meanwhile, the method and the device provided by the invention can realize centering only by controlling the movement of the first conveying assembly without controlling the movement of the drum component, so that the deviation rectification control process of the tire component is simple.
