BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a method for transporting rolls to a roll changer by using transport cars. Rolls prepared with adhesive are loaded onto the transport cars which are then held in an intermediate storage facility.
1. Description of the Prior Art
A method for transporting rolls to a roll changer is known from DE 36 27 454 A1. Here, a roll provided with adhesive means is loaded directly on a transport car which carries this prepared roll until this roll has been placed on clamping cones of the roll changer.
DE 39 10 444 A1 describes an installation for the supply of rolls to roll changers and for removal therefrom, with the installation having a temporary storage. Each one of these roll changers has its own gluing station assigned to it.
It is disadvantageous here that a large number of gluing stations are required.
EPO 0334366A2 describes an installation for transporting paper rolls to a printing press by means of "electrically" guided transport cars.
2. Summary of the Invention
The present invention is directed to a method for transporting rolls to a roll changer.
In accordance with the present invention, this object is attained by providing a plurality of roll transport cars. Each roll is prepared at a preparation station and is then placed back onto its transport car. A plurality of these transport cars, carrying prepared rolls, are held in an intermediate storage facility that is located between the preparation station and the roll changer to which the rolls, on their transport cars, will be delivered.
The advantages which can be achieved by means of the present invention reside in particular in that a prepared roll, which has been provided with adhesive means, remains, without being transferred, on a transport car assigned to it from a preparation station to a roll changer. In this way, damage to the prepared roll is prevented and troubles during roll changes are reduced. It is advantageous that a plurality of prepared rolls, each provided with adhesive means, are stored in a temporary storage facility, so that a preparation station can be assigned to several roll changers.
Different prepared rolls, for example, rolls with different widths, can be stored in this storage facility on assigned, separate tracks and can then be selectively removed.
The flexibility of the roll changer is increased in this way, while simultaneously reducing the number of preparation stations.
BRIEF DESCRIPTION OF THE DRAWINGS
The installation for transporting roll in accordance with the present invention is represented in the drawings and will be described in greater detail in what follows.
Shown are in:
FIG. 1, a schematic representation of an installation for the transportation of rolls;
FIG. 2, a schematic lateral view of a transport car with two receivers;
FIG. 3, an enlarged schematic representation of the rails in FIG. 1 arranged in the area of a roll changer;
FIG. 4, a schematic lateral view of a roll changer.
DESCRIPTION OF THE PREFERRED EMBODIMENT
An installation for the automatic transport of upright rolls 1 from a storage facility 3 to a roll changer 2 of a rotary printing press is constructed as follows:
The upright rolls 1 are transported from a storage facility 3 for a month's supply by a clamping forklift 4 to a roller surface, not represented, and are deposited thereon horizontally (i.e. with a longitudinal axis of the horizontal roll 7 approximately horizontal). The rolls 7 are brought to a first slat conveyor 6 by this roller surface. This slat conveyor 6 transports the horizontal rolls 7 to a first unpacking station 8, by means of which the front covers of the rolls 7 are removed. The first slat conveyor 6 conveys the rolls 7 from this first unpacking station 8 to a second unpacking station 9. This second unpacking station 9 removes a circumferential packaging of the rolls 7 and pivots these horizontal rolls 11 by 90.degree. in a horizontally located plane. These pivoted horizontal rolls 11 are deposited on a second slat conveyor 12 extending parallel in relation
