BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a haulage car transport car for transporting rolls to a roll changer in a web-fed rotary printing press.
DESCRIPTION OF THE PRIOR ART
DE 31 355 A1 describes a movable transport platform for feeding roll carriers usable in rotary printing presses. This prior art transport platform is provided with a pivotable receiver for receiving a second transport car, which has runners.
DE 42 15 739 A1 describes a device for loading and unloading a roll carrier of a printing press. In this device, a deposit trough and rails for receiving a trough car transporting a roll are arranged on a feed car.
SUMMARY OF THE INVENTION
The present invention is directed to a transport car for transporting rolls to a roll changer in a web-fed rotary printing press.
In accordance with the present invention, this object is attained by providing a transport car having rollers which roll in guides. The transport car has at least one receiver which extends perpendicular to the travel direction of the transport car. This receiver is structured to receive a second transport car. A second receiver, parallel to the first, may be used to allow the first transport car to receive a third transport car.
The advantages which can be achieved by means of the present invention reside, in particular, in that all transport cars used for transporting rolls need to be only movable in one direction or degree of freedom. In spite of this, right-angled directional changes of the transport cars are possible without it being necessary to use curves with large bends. In an embodiment of the present invention, using a first transport car with two receivers arranged next to each other on it, loading and unloading of two rolls carried on second and third transport cars can take place simultaneously.
BRIEF DESCRIPTION OF THE DRAWINGS
The transport car 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 to the transport direction of the web-fed rotary printing press and are transported, lying horizontally with their longitudinal axes in the longitudinal direction of the web-fed rotary printing press, to two transfer stations 13, 14.
A portion of the installation for transporting the pivoted horizontal rolls 11, which is located between the transfer stations 13, 14 and the roll changers 2 of the web-fed rotary printing press, is symmetrically constructed in the present exemplary embodiment, so that for the sake of simplicity only the right half will be described in what follows.
The transfer station 13 pushes the rolls 11 onto a firs
