Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tire equipment, in particular to a curling calculation method for marking color bands and a marking device. BACKGROUND

[0002] In the prior art, tires need to be conveyed to a marking station after being tested at a testing station. The existing marking device usually includes multiple marking heads with different shapes, and the tires are marked according to the test results of the tires at the testing station. In each marking process, according to the different test results, a specific shape of marking head or a part of the specific shape of marking head in the multiple marking heads extrudes the color band on the surface of the tire by hot printing to print the color of the color band on the tire, and the printed color band is curled and recycled to release the unprinted color band for the next marking.

[0003] However, the shortest distance of movement of the color band from the completion of the last marking to the present marking cannot be accurately calculated. Since the marks printed on the tire may be different in each marking, the shape and number of the marking heads used in each marking are different. If the distance of movement of the color band is too short, the marks of the present marking will be incomplete. If the distance of movement of the color band is too long, the color band will be wasted, resulting in increased production cost. In addition, the width of each marking head and the distance between the adjacent two marking heads change, which changes the distance of movement of the color band and increases the calculation difficulty of the distance of movement of the color band.

[0004] Therefore, the prior art has the problem that the distance of movement of the color band cannot be accurately calculated, resulting in overlapping or waste of the color band marks during marking. SUMMARY

[0005] The main purpose of the present application is to provide a curling calculation method for marking color bands and a marking device to solve the problem that the distance of movement of the color band cannot be accurately calculated in the prior art, resulting in overlapping or waste of the color band marks during marking.

[0006] In order to achieve the above-mentioned purpose, according to one aspect of the present application, a curling calculation method for marking color bands is provided, which comprises recording the mark information of the color band in the marking area after the completion of the last marking; obtaining the mark information of the color band to be produced in the marking area in the present marking; judging whether the mark information of the color band after the completion of the last marking overlaps with the mark information of the color band to be produced in the present marking; if not, do not rotate the code disc and use the current color band in the marking area for the present marking operation; if yes, rotate the code disc and move the color band in the marking area until the mark information of the color band in the marking area does not overlap with the mark information of the color band to be produced in the present marking.

[0007] Further, the color band in the marking area is divided into a plurality of counting segments in unit length, the value recorded by the counting segment used by the marking head is different from the value recorded by the counting segment not used by the marking head.

[0008] Further, the print information includes a group of values recorded by all the counting segments in the marking area.

[0009] Further, in the process of judging whether the print information of the color band after the last marking is overlapped with the print information of the color band to be produced by the current marking, the group of values produced by the last marking and the group of values to be produced by the current marking are judged.

[0010] Further, in the process of judging the group of values produced by the last marking and the group of values to be produced by the current marking, two values at the same position are judged, when the two values at all positions are different, the print information of the color band after the last marking is not overlapped with the print information of the color band to be produced by the current marking; when the two values at at least one position are the same, the print information of the color band after the last marking is overlapped with the print information of the color band to be produced by the current marking.

[0011] Further, in the process of rotating the code disc and moving the color band in the marking area, the color band moves away from the code disc.

[0012] Further, before rotating the code disc and moving the color band in the marking area, the moving distance of the color band is calculated by the processor.

[0013] Further, in the process of rotating the code disc and moving the color band in the marking area, the minimum distance of the code disc rotation is L, wherein L is the coiled arc length of the minimum resolution of the code disc.

[0014] Further, the marking area is the area between the two ends of the two marking heads located at the two ends of the plurality of marking heads and away from each other.

[0015] According to another aspect of the present application, there is provided a marking device using the above-mentioned method for calculating the curl of a marking ribbon, the marking device comprising a frame, a marking mechanism, a code disk, a code disk detection device and a curl disk, wherein at least a part of the marking mechanism is movably arranged on the frame, the marking mechanism comprising a plurality of marking heads, the plurality of marking heads being movable in a direction towards or away from the marking ribbon; at least a part of the code disk is rotatably arranged on the frame, one end of the marking ribbon is wound out from a marking ribbon roll, and the other end of the marking ribbon is in contact with the code disk; the code disk detection device is arranged opposite to the code disk, and is used for detecting the movement distance of the marking ribbon; the curl disk is located on opposite sides of the marking mechanism in the movement direction of the marking ribbon, the curl disk is connected with a driving assembly, the driving assembly drives the curl disk to rotate to drive the movement of the marking ribbon, the marking ribbon is wound out from the marking ribbon roll, and sequentially passes through the code disk, the marking mechanism and the curl disk.

[0016] According to the technical scheme of the present application, the method for calculating the curl of a marking ribbon for marking comprises: recording the marking information of the marking ribbon in a marking area after the last marking is completed; obtaining the marking information of the marking ribbon to be generated in the marking area in the present marking; judging whether the marking information of the marking ribbon after the last marking is completed and the marking information of the marking ribbon to be generated in the present marking overlap; if not, the code disk is not rotated, and the present marking operation is performed using the current marking ribbon in the marking area; if yes, the code disk is rotated, and the marking ribbon in the marking area is moved until the marking information of the marking ribbon in the marking area and the marking information of the marking ribbon to be generated in the present marking do not overlap.

[0017] In this invention, the used and unused segments of the ribbon within the marking area after the last marking is completed are recorded as imprint information. Similarly, the segments to be used and unused of the ribbon to be generated in the current marking are recorded as imprint information. It is then determined whether the imprint information of the ribbon after the last marking overlaps with the imprint information of the ribbon to be generated in the current marking. If they do not overlap, it indicates that the unused segment of the ribbon corresponding to the marking head required for this marking is needed; therefore, the code disk is not rotated, and the current ribbon within the marking area is used for this marking operation. If they overlap, it indicates that the unused segment of the ribbon corresponding to the marking head required for this marking is needed. If the marking head corresponds to the used segment of the ribbon, the code disk is rotated to move the ribbon within the marking area until the marking information of the ribbon within the marking area does not overlap with the marking information of the ribbon to be marked in this operation. This ensures that before each marking operation, the distance the ribbon moves is adjusted based on the difference between the marking information from the previous marking and the marking information of the ribbon to be marked in this operation, rather than allowing the ribbon to move a fixed distance. This method prevents the ribbon from moving too short or too long, ensuring the integrity of the marking and preventing ribbon waste. Furthermore, the length of the marking information of the corresponding ribbon within the marking area can be adjusted according to the width of each marking head and the distance between two adjacent marking heads, making the ribbon curl calculation method for marking ribbon more widely applicable.

[0023] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The description of the at least one example embodiment is actually only illustrative in nature, and by no means as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0024] In order to solve the problem that the distance of color band movement cannot be accurately calculated in the prior art, resulting in overlapping or waste of color band marks during marking, the present application provides a curl calculation method for marking color band and a marking device.

[0025] As shown in Figure 2 , the marking device comprises a rack, a marking mechanism, a code disc 2, a code disc detection device 4 and a curl disc 5, wherein at least a part of the marking mechanism is movably arranged on the rack, the marking mechanism comprises a plurality of marking heads 3, and the plurality of marking heads 3 can move in a direction towards or away from the color band 1; at least a part of the code disc 2 is rotatably arranged on the rack, one end of the color band 1 is turned out from a color band roll, and the other end of the color band 1 is in contact with the code disc 2; the code disc detection device 4 is arranged opposite to the code disc 2, and the code disc detection device 4 is used for detecting the movement distance of the color band 1; the curl disc 5 is located on opposite sides of the marking mechanism in the movement direction of the color band 1, the curl disc 5 is connected with a driving assembly, the driving assembly drives the curl disc 5 to rotate to drive the color band 1 to move, the color band 1 is turned out from the color band roll, and sequentially passes through the code disc 2, the marking mechanism and the curl disc 5.

[0026] It should be noted that, in the present application, as shown in Figure 2 , the shapes of the plurality of marking heads 3 are different, the marking mechanism further comprises a heating device 6, the heating device 6 is connected with the plurality of marking heads 3, and the heating device 6 marks the color band 1 to the surface of the tire by means of hot printing. Wherein, the marking device uses the curl calculation method for marking color band described below.

[0027] As shown in Figure 1 , the curl calculation method for marking color band comprises: after the last marking is completed, recording the mark information of the color band 1 in the marking area; obtaining the mark information of the color band 1 to be generated in the marking area this time; judging whether the mark information of the color band 1 after the last marking is completed and the mark information of the color band 1 to be generated this time overlap; if not, do not rotate the code disc 2 and use the current color band 1 in the marking area for this time marking operation; if overlap, rotate the code disc 2 and move the color band 1 in the marking area until the mark information of the color band 1 in the marking area and the mark information of the color band 1 to be generated this time do not overlap.

[0028] The present application records the used and unused sections of the color band 1 in the marking area after the last marking as the marking information, records the to-be-used and to-be-unused sections of the color band 1 in the marking area to be generated in the present marking as the marking information, and judges whether the marking information of the color band 1 after the last marking overlaps with the marking information of the color band 1 to be generated in the present marking. If not, it means that the used section of the color band 1 corresponding to the marking head to be used in the present marking, and the code disc 2 is not rotated and the present color band 1 in the marking area is used to perform the present marking operation. If yes, it means that the used section of the color band 1 corresponding to the marking head to be used in the present marking, and the code disc 2 is rotated and the color band 1 in the marking area is moved until the marking information of the color band 1 in the marking area does not overlap with the marking information of the color band 1 to be generated in the present marking, and then the marking operation is performed. Before each marking operation, the movement distance of the color band 1 is adjusted according to the difference between the marking information after the last marking and the marking information of the color band 1 to be generated in the present marking, instead of a fixed distance. This method can prevent the movement distance of the color band 1 from being too short or too long, that is, it ensures the integrity of the marking in the present marking, and prevents the waste of the color band 1. Moreover, the length of the marking information of the corresponding color band 1 in the marking area can be adjusted according to the width of each marking head and the distance between the adjacent two marking heads, so that the calculation method of the color band 1 used for marking is applicable to a wider range.

[0029] As shown in Figure 1 , the color band 1 in the marking area is divided into a plurality of counting sections with a unit length, and the counting sections used by the marking head 3 record different values from the counting sections not used by the marking head 3. In this way, it can be distinguished according to the values recorded by the counting sections which section of the color band 1 has been used after the last marking and which section has not been used, and which section of the color band 1 will be used in the present marking and which section will not be used.

[0030] It should be noted that in the present application, the counting sections used by the marking head 3 record the same value, for example, marked as 1, and the counting sections not used by the marking head 3 record the same value, for example, marked as 0.

[0031] As shown in Figure 1 , the marking information includes a value group recorded by all the counting sections in the marking area. In this way, the value group records the marking information of the complete length of the color band 1 in the marking area.

[0032] As shown in Figure 1As shown, in determining whether the marking information of the color band 1 after the last marking overlaps with the marking information of the color band 1 to be generated in the current marking, the numerical group generated in the last marking and the numerical group to be generated in the current marking are judged. In this way, by judging whether the numerical group generated in the last marking overlaps with the numerical group to be generated in the current marking, it can be known whether the color band 1 corresponding to the marking head 3 required for this marking has been used, thereby determining whether it is necessary to rotate the code disk 2 to move the color band 1 in the marking area.

[0033] It should be noted that in this application, after the current marking is completed, the curl calculation method for the marking ribbon in this application is reapplied for the next marking operation.

[0034] like Figure 1 As shown, during the process of judging the numerical group generated by the previous marking and the numerical group to be generated by the current marking, the two values ​​at the same position are judged. When the two values ​​corresponding to all positions are different, the imprint information of the color band 1 after the previous marking is completed does not overlap with the imprint information of the color band 1 to be generated by the current marking. When the two values ​​corresponding to at least one of the positions are the same, the imprint information of the color band 1 after the previous marking is completed overlaps with the imprint information of the color band 1 to be generated by the current marking. Thus, when the two values ​​corresponding to all positions are different, it means that the color band 1 corresponding to the marking head 3 to be used for this marking is all unused color band 1, and there is no need to rotate the code disk 2 and the marking operation can be performed directly. When the two values ​​corresponding to at least one of the positions are the same, it means that at least part of the color band 1 corresponding to the marking head 3 to be used for this marking is the color band 1 that has been used. It is necessary to rotate the code disk 2 and move the color band 1 in the marking area until the two values ​​corresponding to all positions are different before the marking operation can be performed.

[0035] like Figure 1 As shown, during the rotation of the code disk 2 and the movement of the ribbon 1 within the marking area, the ribbon 1 moves away from the code disk 2. Thus, after being unwound from the ribbon roll, the ribbon 1 first passes the code disk 2 and then the marking area.

[0036] like Figure 1 As shown, before rotating the code disk 2 and moving the color ribbon 1 within the marking area, the processor calculates the moving distance of the color ribbon 1. Thus, after the processor calculates the value D of the moving distance of the color ribbon 1, the color ribbon 1 is directly moved by the value D, preventing the color ribbon 1 from moving the minimum resolution curling arc length L of the code disk 2 each time, saving costs and improving work efficiency.

[0037] It should be noted that in the present application, the processor calculates the moving distance D of the color band 1 in a loop, D=(n+1)*L (n=1), wherein L is the coiled arc length of the minimum resolution of the encoder, n is the number of times of coiling required, if the print information of the color band 1 after the last marking is completed overlaps with the print information of the color band 1 to be generated in the present marking, then n=n+1, the moving distance D of the color band 1 is calculated in a loop until the print information of the color band 1 after the last marking is completed does not overlap with the print information of the color band 1 to be generated in the present marking, then the loop is ended, and the processor calculates the moving distance D of the color band 1, and then the present marking operation is performed.

[0038] As shown in Figure 1 , in the process of rotating the code disc 2 and moving the color band 1 in the marking area, the minimum distance of the rotation of the code disc 2 is L, wherein L is the coiled arc length of the minimum resolution of the code disc 2. In this way, the accuracy of the print information of the color band 1 in the marking area can be improved, and the waste of too much unused color band can be prevented.

[0039] As shown in Figure 1 , the marking area is the area between the ends of the two marking heads 3 that are away from each other among the plurality of marking heads 3. In this way, the marking area includes the width of the plurality of marking heads 3 in the movement direction of the color band 1 and the spacing between the adjacent two marking heads 3.

[0040] It should be noted that in the present application, at least one marking head 3 of the plurality of marking heads 3 performs the marking operation in each marking operation. Preferably, the marking heads 3 are 3, wherein in the movement direction of the color band 1, the width of the first marking head is a, the width of the second marking head is b, the width of the third marking head is c, the spacing between the first marking head and the second marking head is x, the spacing between the second marking head and the third marking head is y, the length of the color band 1 in the marking area is Z, Z=a+b+c+x+y, and the numerical values of a, x, b, y, and c correspond to different numbers of counting segments in the numerical value group in turn, that is, the larger the numerical value of a or x or b or y or c is, the more counting segments it corresponds to.

[0041] It should be noted that in the present application, for example: if in the last marking operation, the first marking head performed the marking operation, and in the present marking operation, one or two of the second marking head and the third marking head need to perform the marking operation, the code disc 2 does not need to be rotated and the present marking operation can be directly performed; for another example: if in the last marking operation, the first marking head performed the marking operation, and in the present marking operation, the first marking head and the second marking head need to perform the marking operation at the same time, the code disc 2 needs to be rotated to move the ribbon 1 in the marking area until the ribbon 1 area used by the first marking head is moved out of the ribbon area corresponding to the first marking head and the second marking head, and then the present marking operation can be performed. The above examples are only two of the many cases of the calculation method for the curling of the marking ribbon.

[0042] It should be noted that the calculation method for the curling of the marking ribbon in the present application is applicable to the use of single and multiple ribbons 1 at the same time, and at the same time, this method is applicable to other ribbon curling systems.

[0043] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects: in the present application, the used section and the unused section of the ribbon 1 in the marking area after the last marking is recorded as the mark information, and the to-be-used section and the not-to-be-used section of the ribbon 1 in the marking area to be generated in the present marking are recorded as the mark information, and it is judged whether the mark information of the ribbon 1 after the last marking and the mark information of the ribbon 1 to be generated in the present marking overlap. If they do not overlap, it means that the unused section of the ribbon 1 corresponding to the marking head needed for the present marking, then the code disc 2 is not rotated and the current ribbon 1 in the marking area is used for the present marking operation. If they overlap, it means that the used section of the ribbon 1 corresponding to the marking head needed for the present marking, then the code disc 2 is rotated and the ribbon 1 in the marking area is moved until the mark information of the ribbon 1 in the marking area and the mark information of the ribbon 1 to be generated in the present marking do not overlap before the marking operation is performed. The distance of the movement of the ribbon 1 is adjusted according to the difference between the mark information after the last marking and the mark information of the ribbon 1 to be generated in the present marking before each marking operation, instead of moving a fixed distance. This method can prevent the distance of the movement of the ribbon 1 from being too short or too long, that is, it ensures the integrity of the present marking, and also prevents the waste of the ribbon 1. Moreover, the length of the mark information of the corresponding ribbon 1 in the marking area can be adjusted according to the width of each marking head and the distance between the adjacent two marking heads, so that the calculation method for the curling of the ribbon 1 for marking is applicable to a wider range.
