"Roll carrier in roll changing device of rotary printing machines .

The invention relates to a bearing axis with slip-on

: pin and side contact flange existing Eollenx carrier in

ρ roller changing devices of rotary printing machines, the

1 with one door direction for the automatic control of the "rolling"

I alternate with impulses depending on the diameter

[the ablauferden rollers by means of their end face scanning

I and light beams directed at photocells.

I Since the beginning of the paper web is glued to the roll change

! the new role to the expiring ϊ-Uiu and the subsequent

Separating the old web from the unwinding roll belongs and this should be done with the smallest possible residual roll diameter is, an exact, absolutely reliable impulse that is free from sources of interference is an essential precondition for a

. _t safe control of the role change processes. To achieve this

\ is the object of the invention.

The invention is characterized by one in the area

i of the smallest diameter of the unwinding paper roll

I opening in the side contact flange and one to a longitudinal center

y axis bore of the bearing axis connecting cross bore as a light

) guidance to an outside of the bearing axis coaxial with her

\ arranged photocell.

f With the invention, the opening rotates in the side contact

! flange with the bearing axis and thus with the paper roll

1; and thus remains covered by this as long as its diameter

! is greater; but as soon as the diameter of the unwinding role

I shrinks below the diameter on which the opening rotates,

I light comes into the opening and leaves the photocell on for a while

address a tight path, which cannot be disturbed by anything from the outside, and trigger the control process. This function can

are not disturbed by out-of-round or loose rolls, nor are they hindered by the excess width of the paper web; also the

Size of storage for extra heavy rolls urui for extra Screeching rolling has no influence on the impulse.

The invention also proposes the outer end wall of the LagerachsG together with the joto :: clie to be covered by an iCappe; this shields the photocell from any false light unu can respond at the lowest brightness that can only enter through the opening in the side contact flange.

However, in order to immediately start with dc;: i the opening mentioned becomes free to let a strong light beam step on the photocell, the invention prefers the arrangement of light guiding elements, the one made of a glass fiber optic ouer of two arranged under 45 Mirrors ooer prisms can exist in the light guide .

The invention also proposes an eccentric arrangement the opening in a rotatable circular disk. So lets the opening is based on various small diameters of the Set the running paper roll, depending on the running speed or depending on the type of paper roll tube durnii piesser used.
