The invention relates to a device for manual replacement of a roller ( ) of a copying machine, the roller being equipped with carrying means, in which it can turn freely around its center axis (X ), and the machine (F) on the one hand having rollers ( ) in a roller pair arrangement for routing through and delivering a recording medium (S) in the form of a sheet or strip, which rollers can be operated in rotation in an adjoining, axially parallel arrangement in the bearing points (L ; L ; L ; L ) of the machine, and are supported by their axial ends, and on the other hand there being manually activated means for releasing/fixing the rollers in their bearing points and for separating/compressing ( ) the rollers in the radial direction for purposes of removing them from and inserting them into their bearing points. To arrive at a device which makes it safer and easier to carry out customer service of the machine, especially replacement and deposition of heavy and large rollers, and which moreover has a simple, compact, economical structure, the roller ( ) has on its two axial ends one carrying handle (T ; T ) each as the carrying means which is located eccentrically to the center axis (X ) of the roller such that the roller hangs down vertically underneath the carrying handles due to its weight in the manual removal from and insertion into the input/output openings of the bearing points (L ; L ) of the machine, which openings run vertically and radially.

Device for manual replacement of the roller of a copying machine

A device for manual replacement and transport of a roller ( ) of a copying machine, for example, which makes it easier and safer for service, replacement and transport of hot, heavy and large rollers. There is provided a protective container ( ) which can be slipped over a roller ( ), which has been released in the machine, and its carrying apparatus. The roller ( ) can be removed from the bearing points (L , L ) of the machine with the protective container ( ) using its carrying apparatus which project out of the protective container, and can be inserted into the bearing points. Carrying handles for the carrying apparatus, enable the roller to be guided into slotted openings and, can be radially inserted into bearing points, and can be removed from them. A transport container ( ) into which the protective container ( ) provided with the roller ( ) can be manually inserted and removed.
