Abstract

To a row of winding stations (1), in which rolls (8) of flat, bendable objects (e.g., printed products) positioned on roll supports (3) are processed or in which such rolls are produced, roll supports (3) are coupled to the winding stations and, if required, are exchanged, the coupled roll supports forming a first row (A) of roll supports parallel to the row of winding stations (1). Roll supports (3) are positioned in readiness for the exchange in a second row (B) of roll supports, which second row (B) is distances from the first row (A) by a transport alley (10). Each roll support in the second row is aligned to the one winding station (1), to which it is to be coupled. For every exchange, the roll support (3) coupled to the winding station (1) is moved transverse to the first row (A) into the transport alley (10) and is transported along the transport alley to its end and there is positioned in a third row (C) of roll supports, which is aligned in the direction of the transport alley (10) and adjoins it.

Claims17

Dependent claims

A method for exchanging roll supports on a plurality of winding stations (1) arranged in a row such that roll supports (3) coupled to the winding stations form a first row (A) of roll supports on one side of the row of winding stations (1), the roll supports each comprising a roll core (7) mounted rotatable around a winding axis, the method comprising the steps of:

providing in addition to the first row (A) of roll supports a second row (B) of roll supports and a transport alley between the first row (A) and the second row (B), and a third row (C) of roll supports adjoined to one end of the transport alley (10) and aligned in the direction of the transport alley,
and a multitude of roll support exchanges each exchange comprising the steps of:
uncoupling a first roll support (3) from the winding station (1) it is coupled to,
removing the first roll support from the first row (A) by moving the first roll support transverse to the transport alley (10) and into the transport alley (10), transporting the first roll support along the transport alley (10), and positioning the first roll support in the third row (C) of roll supports,
bringing a second roll support (3) being positioned in readiness for an exchange in the second row (B), being aligned to the one winding station (1), for which it is destined, and being oriented in the same manner as the first roll support (3) coupled to said winding station (1), into the first row (A) by moving the second roll support transverse to the transport alley (10) and across the transport alley (10) into the first row (A), and,
coupling the second roll support to said winding station (1).

3 more elements

An installation for exchanging roll supports on a plurality of winding stations (1) arranged in a row, said installation comprising:

a plurality of roll supports (3), a first group of the roll supports being coupled to the winding stations to form a first row (A) of roll supports on one side of the row of winding stations (1), a second group of the roll supports being spaced from the first group and being disposed in a second row (B) and a third group of the roll supports being disposed in a third row (C), the roll supports each comprising a roll core (7) rotatably mounted around a winding axis, wherein the roll supports positioned in the second row (B) are in readiness for the exchange,
a transport alley (10) running between the first and the second rows (A and B) of roll supports, and wherein the third row (C) of roll supports runs in a direction of the transport alley (10) and adjoins an end of the transport alley (10), and
a transverse transport means connecting the first and the second row of roll supports for performing transport steps in two directions transverse to the first and second row (A and B) of roll supports and across the transport alley (10), and
a longitudinal transport means (30) for performing transport steps along the transport alley (10) in a direction towards the third row (C) of roll supports and for positioning roll supports in the third row (C).
