This marking was generally done by a worker writing on the rubber fabric with a marking pen using quick-drying ink, or by attaching the tag to the rubber fabric and writing on it (for example, on a rolled steel plate). There is a marking device designed to mark the area in Japanese Utility Model Publication No. 58-53135).

<Problems that the invention aims to solve> However, such conventional means require manpower, and when writing with a pen, the rubber fabric is colored by ink, so it is necessary to remove the markings when molding the rubber. I needed to.

Furthermore, in the method of using tags, the tags may come off when the rubber fabric is moved, and it is necessary to remove the tags during molding.

<Means for solving the problem> This invention was made to solve the above problem, and consists of a rotatably supported printing roller, a pair of magnetic adsorbers forming the mounting legs, and a pair of magnetic adsorbers that form the mounting legs. The rubber fabric marking device is equipped with a height-adjustable auxiliary leg located outside the magnetic adsorption device, the printing roller having a replaceable printing element, and a height adjustment mechanism.

<Function> This device is constructed as described above, and the printing roller of this device is disposed below the roller of the rubber kneading machine on the side that rotates along with the rubber dough. At this time, the kneading machine roller axis and the printing roller axis are made parallel to each other, and a predetermined distance is maintained between the kneading machine roller outer circumferential surface and the printing roller outer circumferential surface, and the kneading machine roller is fixed to the lower base of the kneading machine by a magnetic adsorbent.

Then, the device is stably fixed by tightening the auxiliary legs, and the printing element comes into pressure contact with the surface of the rubber dough that has been turned into a flat plate by rotating along with the kneading machine rollers, and as the rubber dough rotates. The printing roller rolls. By pressing and rolling the printing elements, a predetermined display mark made of one or more printing elements is formed in a pressed manner on the surface of the rubber fabric, thereby performing marking.

Then, roller frame covers 8 and 13 are arranged on both sides of the roller frame 3, a shaft 14 is passed through the center part, and a required number of printing elements 6 are installed in each groove 4, so that the printing roller 2 is formed.

The support member 16 is made of an upwardly facing U-shaped member, and has a shaft support 16a formed inside its upper end, and a pillar 17 having a rectangular cross section is formed in a hanging shape at its lower end. A shaft 14 is rotatably supported on the shaft support 16a of the support member 16 in a cross-sectional shape, and a coiled spring (not shown) is wound around the shaft 14 to move the roller frame covers 8, 13 toward the roller frame 3 side. It is formed so as to be pressed against it.

By rotating the roller frame cover 8 using the knob 11, the protrusions 10 are fitted into the notch holes 5 at every 15 degrees, and when the notches 9 open the grooves 4, the printing element 6 is attached and detached. In addition, at the position where the roller frame cover 8 is rotated 15 degrees left and right from the above position and fitted into the notched hole 5, the roller frame cover 8 closes the 12 grooves 4 to prevent the printing element 6 from coming off, and the printing roller 2 presses the stamp. It becomes operational.

The column part 17 is fitted into a sliding support part 21 provided on the base body 20 and is formed to be movable in the vertical direction. This vertical movement mechanism, that is, the height adjustment mechanism 18, includes a female screw vertically provided in the support column 17, and a male screw that is screwed into the female screw and whose lower end is pivotally supported on the base body 20. , is a rotation-linear conversion mechanism consisting of a bevel gear provided at the bottom of a male thread, and a bevel gear that meshes with the bevel gear and has a rotating shaft perpendicular to the male thread, and this rotating shaft is It is pivoted to the base body 20, and one end thereof is connected to the base body 20.
