Description

  The present invention relates to a tire marker pen for marking or correcting a mark such as a balance mark or a uniformity mark on a tire, a method for marking a tire using the same, and a desired mark added or corrected by this method. Regarding tires.

  In general, each manufactured tire is provided with a balance mark, a uniformity mark, etc., and then subjected to a product inspection of the tire. Conventionally, in attaching such a mark to a tire, a method of writing a mark with a marker pen and a method of marking a mark by a stamp method have been mainly employed.

  However, when a mark is written with a marker pen, the shape of the mark tends to be uniform, and it takes time to fill the mark, which causes a problem in terms of efficiency.

  Further, when marking a mark by the stamp method, it is necessary to maintain a sharpness by quickly replacing the stamp with a new stamp head when the head becomes sticky after long-term use of the stamp and the tolerance of the mark cannot be satisfied. Further, in order to maintain the sharpness of the mark, it is necessary to periodically clean the stamp. In other words, it is necessary to saturate the felt of the stamp many times (for example, once per 16 tires), and it is difficult to replenish the ink, and the color of the mark fades with use. Sometimes it came. Further, the stamp method has a problem that a clean shape cannot be engraved because ink remaining without being imprinted solidifies on the felt surface of the stamp. Furthermore, when ink is replenished to the stamp, precipitation of the ink in the container is considered, so that the ink container must be stirred before replenishment.

  On the other hand, in recent years, some users have strictly demanded the beauty of various marks attached to tires, and improvement is required.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to eliminate the above-mentioned problems of the prior art, and to efficiently apply or correct a mark to a tire in a state where the sharpness and shape are maintained well, and a tire marker pen that can be corrected. It is an object of the present invention to provide a method for marking a tire and a tire with a desired mark by this method.

  As a result of intensive studies to solve the above problems, the present inventors achieved the above object by marking the mark with a marker pen itself for applying a desired mark to a tire in a stamp format under a predetermined condition. As a result, the present invention has been completed.

  That is, the tire marker pen of the present invention is a marker pen for attaching or correcting a mark such as a balance mark or a uniformity mark on a tire, and the tip of the pen core has the same shape as the mark, and the stamp The mark can be stamped on the tire in the form.

  In the tire marker pen of the present invention, since the penetrating degree of ink into the core varies depending on the size of the mark and the ink used, the length of the pen core is set so that the mark is imprinted by one engraving. It is preferable that the amount of ink is appropriately controlled and / or the amount of ink is appropriately controlled. Moreover, it is preferable that the edge of the tip of the pen core is chamfered, or the edge of the tip of the pen core is a curved surface. Thereby, it is possible to effectively prevent the pen core from being scattered due to use. Furthermore, it is preferable that the cross-sectional diameter of the tip end region of the pen core is larger than the cross-sectional diameter of the pen core main body. Thereby, the tip of the pen core has a function as a stopper, and the pen core can be prevented from being buried in the ink container.

  Moreover, this invention is a marking method characterized by marking a desired mark on a tire using the said marker pen for tires.

  Furthermore, the present invention is a tire characterized in that a desired mark is imprinted by the marking method.

  According to the marker pen of the present invention, it is possible to efficiently mark or modify a mark continuously on a tire while maintaining good definition and shape. Therefore, the mark imprinted on the tire by the marking method on the tire using this marker pen shows a high definition, a uniform shape, and an excellent aesthetic appearance.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
A marker pen 1 according to a preferred embodiment of the present invention shown in FIG. 1 is a marker pen that supplies ink 20 in an ink container 2 to a pen core tip 11 serving as a marking portion.

  The ink container 2 that is the main body of the marker pen 1 shown in FIG. 1 is made of, for example, a synthetic resin or metal, and has a medium diameter portion 3 and a small diameter portion 4 on the tip side via a taper portion 5. It is united. In the small-diameter portion 4, the pen core tip portion 11 is slidably fitted. In the middle diameter part 3, the thick part 12 of the pen core tip part 11 is accommodated, and the taper part 5 has a stopper function to lock the thick part 12 and prevent the pen core tip part 11 from falling off. is doing. The thick portion 12 has a stopper function and a function of occluding marker pen ink. The ink container 2 contains a stirrer 30 for facilitating stirring of the ink 20 inside.

  In the example shown in the figure, the edge 14 of the pen core tip 11 is chamfered, so that the pen core tip 11 is not scattered with use. The shape of the mark generated by the marking by the pen core tip 11 is circular, but other shapes such as a square, a triangle, and a star can be used as desired. Further, since the ink soaked into the pen tip 11 differs depending on the size of the mark to be stamped and the ink used, the length of the pen core 11 so that the mark can be satisfactorily stamped by one stamp. Is preferably controlled appropriately. For the same reason, it is preferable to select the hardness of the pen core tip 11 as appropriate.

  The material of the pen tip 11 is not particularly limited as long as it can be impregnated with marker pen ink. For example, natural fiber, animal hair fiber, polyacetal resin, acrylic resin, polyester resin , Polyamide fiber, polyurethane resin, polyolefin resin, polyvinyl resin, polycarbonate resin, polyether resin, parallel fiber bundle consisting of a combination of two or more of polyphenylene resin, bundles of felt, etc. A fiber core obtained by processing or resin processing of these fiber bundles, or a porous body obtained by fusing various plastic powders or the like is used.

  In the preferred example shown in FIG. 1, the rear portion 13 of the pen core tip 11 is elastically supported by the spring mechanism S, and at the same time, the ink 20 can penetrate well into the pen core tip 11. Yes. That is, even when the pen core tip 11 is pushed in at the time of marking, the spring mechanism S pushes back until the thick portion 12 of the pen core tip 11 is locked to the taper portion 5, and at the same time, the ink 20 is discharged. It is sent to the pen core tip 11.

  In the spring mechanism S, a disc 15 having a circular hole in the center is disposed apart from the rear portion 13 of the pen core tip portion 11, and a cylindrical first support portion 9 is fixed to the disc 15. Further, a plurality of rod-like second support portions 10 that support the stopper ring 6 that locks the spring 16 are extended from the cylindrical first support portion 9. The stopper ring 6 and the center hole of the disk 15 are provided with a liquid stopper 8 and a shaft 7 fixed to the outer periphery, and the rear part 13 of the pen core tip 11 is pushed in at the time of marking. When the shaft body 7 is pushed in, the liquid stopper 8 is separated from the disk 15 and the ink 20 flows toward the tip 11 of the pen core. At the same time, the shaft body 7 is penetrated and the liquid stopper 8 and the stopper ring. The shaft body 7 pushes back the rear portion 13 of the pen core tip portion 11 by the action of the spring 16 arranged between the tip end portion 11 and the shaft 16.

  Instead of the spring mechanism S, the ink container 2 may be filled with an ink occlusion body (not shown). The ink occlusion body is impregnated with ink, for example, natural fiber, animal hair fiber, polyacetal resin, acrylic resin, polyester resin, polyamide resin, polyurethane resin, polyolefin resin, polyvinyl resin, Sintered bodies such as fiber bundles, felts, sponges, resin particle sintered bodies, resin fiber sintered bodies made of one or a combination of two or more of polycarbonate resins, polyether resins, polyphenylene resins, etc. Etc.

  As shown in FIG. 2, the marker pen 101 according to another preferred embodiment of the present invention is different from the marker pen 1 of the above preferred example in the shape of the pen core tip 21. As shown in FIG. 2, the pen core tip 21 of the marker pen 101 has a cross-sectional diameter “a” at the tip of the pen core larger than the cross-sectional diameter “b” of the pen core main body. Thereby, the tip of the pen core also has a function as a stopper, and the pen core can be prevented from being buried in the ink container.

  The ink for the marker pen of the present invention is not particularly limited as long as it is an ink having each compounding composition used in a tire, and a known ink can be used.

  In the marking method of the present invention, the tip end of the marker pen is formed into a desired mark shape, and the desired marking can be continuously performed by pressing the tip end of the pen core against the tire. As a result, it is possible to solve the problems such as the unevenness of the mark shape that occurs when the mark is written with the conventional marker pen, and the problem that it takes time and is not efficient. In addition, it is possible to solve the problem in the case of marking with the conventional stamp method, for example, the problem of frequent head replacement and stamp felt. Therefore, a tire in which a desired mark is engraved by the marking method of the present invention is excellent in aesthetic appearance and can sufficiently satisfy the user's request.

Hereinafter, the present invention will be described based on examples.
Conventional example 1
