Definitions
- the present invention relates to a uniformity inspection system for inspecting the uniformity characteristics of assembled tires, correcting the uniformity characteristics as necessary, and re-inspecting the assembled tires.
- product tires are usually shipped after various product inspections such as appearance inspection and shape measurement.
- the tire uniformity was measured by applying a load to the rim-assembled tire 12 against a rotating drum 11 corresponding to the road surface, and pressing the tire 12 and drum 11 together.
- the load fluctuation component (RFV), the lateral force fluctuation component (LFV), and the longitudinal force fluctuation component (TFV) are measured, and Fig. 3
- the displacement meters 13 a and 13 b are pressed against the tread portion 12 a and the side portion 12 b of the rotating tire 12 via the rolls 14 a and 14 b to Measure longitudinal dimensional non-uniformity (RR) and lateral dimensional non-uniformity (LR).
- the measured uniformity characteristic is within the specified value, it is regarded as a non-defective product. If the measured characteristic exceeds the specified value, for example, the mounting condition with the rim is corrected, or a correction device such as a puff machine is used. After correcting the tire by removing uneven portions and convex parts of tire run-out using the method, remeasure the uniformity waiting time of the corrected tire.
- Fig. 4 is a diagram showing the outline of a conventional uniformity inspection line.It is transported on the conveyor 21C of the automatic sorting line 21, and after finishing the appearance inspection on the conveyor 21C, the sorted tires 12 are sorted. , Sequentially, to a uniform inspection line 22 equipped with multiple uniformity inspection devices (hereinafter referred to as UF machines) 22M. Each UF machine 22M measures the uniformity characteristics as described above.
- Each of the above UF machines 22M is a device having both a function of measuring the uniformity and a function of modifying the characteristics of the uniformity. If this is the case, this is sent as a non-defective product to the transfer conveyor 23 C of the transfer line 23 and sent to the subsequent process. If the specified value is exceeded, the tire is modified using a modification device (not shown) such as a puff machine provided in the UF machine 22M, and then the uniformity characteristics of the modified tire are measured. Remeasure. After the re-measurement, if the modified uniformity characteristic of the tire is within the specified value, it is sent to the post-process as a non-defective product, and if it exceeds the specified value again, it is regarded as a defective product. Sent to the collection conveyor 24 C for collection.
- the number of UF machines 22M mentioned above is limited to the minimum necessary number according to conditions such as the number of tires produced, the number of production sizes, and the predicted number of uniformity characteristic corrections.
- the automatic line might not function properly.
- the uniformity measurement time of the UF machine 22 M is almost constant for each size tire, the uniformity characteristic correction time is several times the uniformity measurement time, although there is a difference depending on the value of the size uniformity characteristic. Therefore, if the proportion of tires that modify the uniformity characteristics increases, the number of tires that can be processed by the 22M UF machine will decrease. Therefore, the capacity of the automatic line is reduced, such as the tire 12 overflowing to the automatic sorting line 21.
- the tires 12 on the automatic sorting line 21 are manually removed. It was necessary to make the automatic line work by temporarily transporting it to a storage location. At the stage when the load on the automatic line was reduced, extra work such as returning the stored tire 12 to the automatic line was necessary.
- the present invention has been made in view of the conventional problems, and is intended to efficiently perform a uniformity inspection even when the number of tyres for correcting the uniformity characteristics fluctuates. It is an object of the present invention to provide a tire uniformity inspection system that can be used. Disclosure of the invention
- the present inventors have conducted intensive studies, and as a result, the line for measuring the uniformity and the line for correcting and re-measuring the uniformity characteristics are separated from each other, so that the number of tires for correcting the uniformity characteristics is reduced.
- the present invention has been found that it is possible to operate the uniformity inspection line without any delay even when there is a large fluctuation.
- the tire uniformity inspection system includes a uniformity inspection device, measures the uniformity characteristics of the tire put into the inspection line, and measures the measured tire uniformity characteristics. If the specified value is exceeded, the unit's uniformity inspection system, which corrects and remeasures the uniformity characteristics of the tire, has only the uniformity measurement function, and newly inserted tires
- a separate line dedicated to repairs equipped with a second uniformity inspection device that re-inspects the uniformity characteristics of the new tires is provided separately to measure the uniformity of newly introduced tires, and to correct and re-measure the uniformity characteristics. It is configured to operate in a separate system.
- FIG. 1 is a diagram showing a configuration of a uniformity inspection line according to the best mode of the present invention.
- FIG. 2 is a flowchart showing a procedure for inspecting a community.
- FIG. 3 is a diagram showing a method of measuring a uniformity.
- FIG. 4 is a diagram showing the configuration of a conventional uniformity inspection line. BEST MODE FOR CARRYING OUT THE INVENTION
- FIG. 1 is a diagram showing the outline of the uniformity inspection line according to the best mode, and 21 is sorting and sorting the tires 1 and 2 while performing an appearance inspection of the tires 12 on a conveyor 21C.
- Automatic sorting line 1 that has only a uniformity measurement function and is used exclusively for judgment with multiple UF machines 2 M that measure and inspect the uniformity of the sorted and sorted tires 1 2
- the tire 12k which has both the line 2 and the uniformity measurement function and the uniformity characteristic correction function, and has the uniformity characteristic determined to have exceeded the specified value in the judgment dedicated line 2 above, is corrected.
- the second UF machine 3 M which is used to re-measure and inspect the uniformity characteristics of the selected tires
- the transfer line provided with a transfer conveyor 23 C that transfers 12 m of tires judged as good in the line 2 for exclusive use of judgment and the line 3 for correction only to the post-process.
- This is a recovery line equipped with a recovery conveyor 24C for recovering evening 12 ⁇ determined to be defective.
- the tires 12 sorted and sorted by the visual inspection from the automatic sorting line 21 are put into the first UF machine 2 ⁇ of the dedicated judgment line 2, and the tire uniformity is measured (step S 1). 0), it is determined whether or not the uniformity characteristic of the tire is within a predetermined value (step S11). If the uniformity characteristics are within the specified values, the above tires are mounted on the conveyor 23C of the transfer line 23 as non-defective tires 12m and transported to the subsequent process (Step S12). If the value is exceeded, the tire 12 k is sent to the correction line 3 (step S 13), and the second UF machine 3M corrects the tire 12 k and corrects the tire 12 k.
