A web unwound from a web mounted on a paper feeder 1 is guided to a folding machine 6 through a plurality of guide rollers 2, printing units 3 and 4, and a large number of guide rollers 2 provided on a web path 5.

3 rotates as the paper runs. Further, since the roller cell 13 requires a certain level of strength, it is generally made of steel or aluminum alloy. In addition, chrome plating is applied to prevent ink from adhering to the web, and although the surface is polished smooth, the coefficient of dynamic friction is relatively high, and when running for a long time, ink and paper powder mix and cause damage to the outer peripheral surface. It sticks to and accumulates on the surface. A cleaning device (not shown) is provided to remove this.

に取り除くことが出来ない。During normal operation, the roller cells of the guide rollers are rotated by the running of the web with which they are in contact, and ink on the printed surface of the web is transferred to and adheres to the outer peripheral surface of the roller cells. During low speed operation, this adhered ink is re-transferred to the following web and contaminates the web. Ink adheres to the outer peripheral surface of the roller cell from the web due to contact (
In addition to dislocation caused by pressure welding, the moment of inertia of the roller cell is large, so when the web accelerates or decelerates or changes in speed during operation, the speed difference that occurs because the roller cell speed does not immediately respond to changes in web speed causes the ink to deteriorate. This is because the ink is applied to the roller cell surface while being rubbed, and the ink adhesion strength due to this rubbing is strong and cannot be easily removed when cleaning the ink.

ある。Next, when the chrome plating is applied to the outer circumferential surface of the roller cell, ink and paper powder mix and stick to the outer circumferential surface when the roller cell is operated for a long period of time, and they accumulate, so it is necessary to stop the printing machine from time to time. It is necessary to wipe them off. SUMMARY OF THE INVENTION An object of the present invention is to provide a guide roller for a rotary printing press that is less prone to ink adhesion and is easy to wash and remove even if ink adhesion occurs.

る。[Means for Solving the Problems] In order to prevent ink from adhering to the outer circumferential surface of the roller cell of the guide roll for a long time, (1) the roller cell is made of carbon fiber-reinforced plastic stick with a small moment of inertia. (2) Use a material that has a coefficient of dynamic friction, adhesive strength, and other surface energies several steps lower than that of chrome plating. For this purpose, the outer peripheral surface of the roller cell is coated with fluororesin or coated with fluororesin or silicone.

着を長時間阻止することが出来る。[Function] (1) The moment of inertia of carbon fiber-reinforced plastic is approximately 1/10 that of steel pipe, which is significantly lower. Therefore, the speed of the roller cell quickly responds to changes in the speed of the web, and there is almost no difference in speed between the two. Therefore, no dislocation occurs due to rubbing due to the difference in speed, and even if ink adheres, the adhesion strength is weak and it can be easily removed. (2) Since the coefficient of dynamic friction and adhesive force, which cause ink adhesion, are several orders of magnitude lower than those of chrome plating, ink adhesion can be prevented for a long time.

。DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an ink adhesion prevention guide roller according to the present invention. In the structure of this guide roller 21, a cylindrical carbon fiber reinforced plastic roller cell 22 is attached to the support shaft 11 via a bearing 12. The outer circumferential surface of the roller cell 22 is covered with a fluororesin tube 23 which has been heat-shrinked using a commercially available hot air gun and has a dynamic friction coefficient and adhesive strength several orders of magnitude lower than that of the chrome plating inserted into the outer diameter of the roller cell 22. There is. or dotted line 24
As shown in , it is coated with fluorine resin or silicone, which has a coefficient of dynamic friction and adhesive strength several orders of magnitude lower than that of chrome plating. The former fluororesin tube 23 can prevent ink transfer for a long time, and even if transfer occurs, it can be easily wiped off with a cleaning liquid that has penetrated into the web while the web is running. The latter coating layer 24 prevents ink transfer for a longer period of time than the former, and even if it adheres, the amount is so small that it hardly needs to be removed. This prevention of ink adhesion is due to the ability of the fluororesin or silicon coated on the roller cell 22 to repel ink adhesion, but since the roller cell 22 is made of carbon fiber reinforced plastic, its moment of inertia is lower than that of conventional steel. The moment of inertia of the roller cell 13 is as low as 1/10, and since the roller cell 22 immediately responds to and follows speed fluctuations of the web, there is almost no speed difference between the two, and the ink on the web is distributed around the outer periphery of the roller cell 22. Based on not being rubbed against surfaces.

かくてすむ。[0012] Ink transfer from the web can be prevented for a long time, and even if ink does transfer, the degree of ink adhesion is weak and can be easily removed with a cleaning liquid that has penetrated into the web. In particular, coatings prevent ink transfer for a longer period of time than films, and there is almost no need for cleaning. Therefore, the length of the lost web can be shortened.
