Description of the Related Art For example, a guide roller in a guide roller device of a rotary press is appropriately arranged so as to guide a material sheet, which is traveling from a sheet feeding section through a printing section toward a folding section, in a desired direction. By the frictional force with the running paper, it rotates at a peripheral speed substantially the same as the running speed of the running paper. Therefore, foreign matter such as ink adheres from the contacting paper to the outer peripheral surface of the guide roller, which comes into contact with the paper after being printed in the printing section, and stains the subsequent paper to deteriorate the print quality. Further, the foreign matter such as the adhered ink needs to be removed manually by a worker or by a dedicated device after the printing is stopped or after the printing is completed.

One or more guide rollers are provided in association with each other by a transmission mechanism so that the rotational peripheral speed of at least one guide roller is different from the rotational peripheral speeds of the other guide rollers, and travel with the outer peripheral surfaces of all the linked guide rollers. All the linked guide rollers are made to rotate in a state where the rotational torques due to the frictional forces acting on the inside of the paper stock are balanced, and there is a slight difference between the rotational peripheral speed and the running speed of the paper stock. The rubbing is performed by rubbing the outer peripheral surface of the guide roller with the running paper, and foreign matter such as ink is prevented from adhering to the guide roller, and the guide roller is automatically wiped.

に擦ることができなかった。In the conventional device, the frictional force due to the contact between the paper and the outer peripheral surface of the guide roller is used as the rotational driving force of the guide roller, and the difference between the peripheral speed of rotation of the guide roller and the traveling speed of the paper is set. Has an advantage that the outer peripheral surface of the guide roller can be rubbed by the running paper without causing unnecessary tension load on the paper. However, a transmission mechanism device for maintaining a plurality of guide rollers linked to each other is required, which complicates the structure, increases the associated work such as maintenance, and further increases the cost. In addition, the rotational peripheral speeds of the plurality of guide rollers that are kept linked by the transmission mechanism are such that the rotational torques due to the frictional forces acting between the outer peripheral surfaces of all the linked guide rollers and the running stock are balanced. Then all the linked guide rollers rotate. Therefore, when the frictional force acting between one of the linked guide rollers and the running stock is extremely large as compared with the frictional force acting between the other guide roller and the running stock, the above 1 One guide roller rotates without being affected by other guide rollers, and there is almost no difference between the peripheral speed of rotation and the running speed of the paper stock. The outer peripheral surface of this guide roller is effective depending on the paper stock that is running. Could not rub against.

Further, when rotating in contact with the running paper, the peripheral speed of rotation surely differs from the running speed of the paper. It is intended to provide a guide roller to be obtained.

However, since the large diameter peripheral surface and the small diameter peripheral surface have different radii, the angular velocity of the large diameter peripheral surface and the small diameter peripheral surface can be calculated from the relational expression of angular velocity (ω) = running speed (v) / radius (r) of the paper stock. , Inevitably trying to be different.

この両周面３，４でのみ接触することになり、従って、
この料紙Ｗの接触面には必ずすべりが伴うことになる。 Next, the paper W by the guide roller 1
I will explain the guide. When the running paper W is guided by the outer peripheral surface 2 of the guide roller 1, the guide roller 1 rotates as the paper W travels due to the frictional force between the outer peripheral surface 2 and the paper W in contact therewith. By the way, the outer peripheral surface 2 of the guide roller 1 has a large diameter peripheral surface 3 and a small diameter peripheral surface 4.
The raw paper W travels at a speed V while being in contact with the large diameter peripheral surface 3 and the small diameter peripheral surface 4 all at once. Therefore, the large-diameter peripheral surface 3 tries to rotate at an angular velocity of V / R3,
The small diameter peripheral surface 4 tries to rotate at an angular velocity of V / R4. This
The angular velocity ω at the time of is the traveling speed of the stock V, the large diameter peripheral surface portion
When the radius of R is R3 and the radius of the small diameter peripheral surface is R4,
The friction force due to the slip between the large diameter surface and the paper and the small diameter circumference
The frictional force due to the slip between the surface and the paper is balanced and has a relationship of (V / R3) <ω <(V / R4) . As a result, the outer peripheral surface 2 of the guide roller 1 is integrally formed with the large diameter peripheral surface 3 and the small diameter peripheral surface 4, so that the large diameter peripheral surface 3 and the small diameter peripheral surface 4 can rotate independently at different angular velocities. Therefore, the guide roller 1 rotates at an angular velocity ω in which the angular velocity V / R3 about which the large-diameter peripheral surface 3 tries to rotate and the angular velocity V / R4 about which the small-diameter peripheral surface 4 tries to rotate influence each other. As a result, slippage occurs between the large-diameter peripheral surface 3 and the raw paper W and between the small-diameter peripheral surface 4 and the raw paper W, that is, between the outer peripheral surface 2 of the guide roller 1 and the raw paper W. The outer peripheral surface 2 of 1 is rubbed by the running paper W. Therefore, the outer peripheral surface 2 of the guide roller 1
Is reliably rubbed by the paper W that is in contact therewith and travels, foreign matter such as ink does not adhere, and is automatically cleaned. In addition, between the large-diameter peripheral surface and the paper W, and between the small-diameter peripheral surface and the paper
In order to cause a slip between each of the W and
Is the rotational force received from the paper W on each peripheral surface.
Should be approximately the same. This rotational force is applied to each peripheral surface.
Is the product of the tangential force and the radius received from the paper W.
However, this radius is large and small on both sides, so
The tangential force on the radial surface is
Less than tangential force. This tangential force is
Contact force applied to the paper web W of the surface, the contact area及 beauty friction coefficient
Is decided. Therefore, to change this tangential force,
Assuming that the contact force is almost the same on both sides, the contact area and friction
The friction coefficient may be changed appropriately. From the above, the outer peripheral surface 2 of the guide rollers 1, fees for traveling in contact with it
It is reliably rubbed by the paper W, foreign matter such as ink does not adhere, and it is automatically cleaned. Also, the large diameter peripheral surface and the small diameter
Being adjacent to the peripheral surface with a step
Therefore, the paper W that comes into contact with the outer peripheral surface of the guide roller 1 is
Only the two peripheral surfaces 3 and 4 come into contact with each other, and therefore,
The contact surface of the paper W will always slip.

The outer peripheral surface 2 of the guide roller 1 may be formed by appropriately mixing surfaces having different properties. The form of the outer peripheral surface is a form in which the outer peripheral surface of the equal diameter roller is removed to provide the small diameter peripheral surface 4, a form in which an appropriate outer peripheral surface of the equal diameter roller is added to provide the large diameter peripheral surface, a mold Therefore, any form such as a form in which a roller having a large diameter peripheral surface 3 and a small diameter peripheral surface 4 is formed at once is possible. The point is that it includes design modifications that do not depart from the scope of the claims.
