Description

Technical area

The invention relates to a storage and retrieval device and a device comprising such a device for preparing and temporarily storing paper rolls and feeding them to at least one roll stand. Systems of this type are used in roll cellars by printers to supply the printing presses with paper. The invention also includes a method for operating the plant. Such storage and retrieval devices are eg in EP 1245524 . EP 1329397 . WO 00/68115 and WO 00/51931 disclosed.

State of the art

There are generic storage and retrieval devices are known, which bear as a recording device rails for receiving a storage vehicle, which enters from the chassis in storage channels and there record each at a storage place a roll of paper or can be stored. Such storage vehicles have bearing surfaces which serve to receive the roll of paper and lifting and dropping the same can be raised and lowered. Out EP 1 382 561 A1 Such a storage and retrieval device is known, in which the receiving device also has raised and lowered claws, which are extendable on both sides transversely to the direction of travel of the chassis.

However, a paper roll can not be rotated about a vertical axis with this storage and retrieval machine. A Setting the Wickelsinnes a roll of paper to a target value is therefore not possible, so that additional complex and space-requiring facilities such as turntables are required.

Out WO 89/04 284 A1 is a storage control unit with a storage vehicle is known, which has a bogie on a chassis, which carries the rail for receiving the. However, the bogie only serves to align the storage vehicle so that it can move into storage channels on both sides of the web, along which the storage and retrieval device is moved, with a fork-like recording for the paper roll ahead, as it can only take a paper roll or put down. Even with this storage and retrieval device an adjustment of the winding sense of a paper roll is therefore not possible, since the orientation of the bogie must be based on the required orientation of the storage vehicle. The chassis also carries no raised and lowered claws, so that a lifting paper rolls from the usual used in roller baskets simple, not having a raised and lowered support surface car is not possible. The transfer of a paper roll from such a car to the storage and retrieval device and vice versa is therefore not readily possible.

WO 98/12 132 shows a storage and retrieval device with a continuous track section on a bogie on which cars of the type usually used in roller baskets can drive up. Obviously, the bogie only serves to align the wagons, which run up from a track connecting to a head end of the web of the storage and retrieval device, and then, according to the method of the storage and retrieval device, into a traverse to this web running tracks of an intermediate storage must retract. An adjustment of the Wickelsinnes a roll of paper by means of the bogie is apparently not provided and also not required, since there are fixed turntables on which such a step can be performed. A device with which the roll of paper on the storage and retrieval machine could be lifted off the cart is not present. The paper roll is loaded on a cart at a preparatory station and remains in the intermediate store and until the paper roll is received by the roll stand on the same. This requires a return of the car in oncoming traffic or on additional tracks and complicates the control or construction of the system or both.

Presentation of the invention

The invention is based on the object to provide a storage control unit, which offers the possibility to set the winding sense of paper rolls to a desired value and also allows the takeover of paper rolls of simple cars and the transfer of paper rolls to such cars. This makes it possible to build systems with intermediate storage very easily, without turntables and additional tracks for the return of cars and similar relatively expensive and much space-requiring facilities and also to keep their control simple, so that no unexpected difficulties occur during operation. A corresponding system and a method for their operation also belong to the scope of the invention.

Ways to carry out the invention

The plant according to the invention has (FIG. 1) an intermediate storage 1 with two parallel rows 2a, b of storage spaces 3 on which prepared paper rolls 4 can be stored lying with axes aligned in a transverse direction transverse to the longitudinal direction and one between the same running web 5, along which a storage and retrieval device 6 is movable. The intermediate storage 1 serves primarily as a buffer storage, which allows work interruptions in the role preparation in further printing operation.

In the entrance area, a ramp 7 is arranged, from which by stapled stapler delivered from a main warehouse packed paper rolls 4 'rolled as needed on a carriage 8 of known type and a preparation station 9 and further fed to the intermediate storage 1. A Zuführgeleise 10, on which the carriage 8 reverses, leads in the longitudinal direction from the end of the ramp 7 via the preparation station 9 to a takeover place 11 at the end of the web. 5

The storage bins 3 each have as trained by the track 5 short Stichgeleise bearing tracks 12, on each of which a car 8 is parked, which carries the prepared paper roll 4. Each of the two rows 2a, b of storage spaces 3 is interrupted by a transfer station 13a, b. From the opposing transfer points 13a, b extend in the transverse direction supply rails 14a, b, which lead to two on both sides of the intermediate storage 1 arranged roll stands 15a, b with aligned in the transverse direction Abrollachsen and traversers with transversely continuous track sections. On b is arranged in each case in the continuation of the supply jaw 14a; b a Abstellgeleise 16 formed as Stichgleeise, which can accommodate a carriage 8, which is loaded with a sleeve basket 17.

The storage and retrieval device 6 according to a first embodiment (Fig. 2, 3) has a chassis 18 which is movable on rails along the web 5 and on which a bogie 19 is rotatably mounted about a vertical axis 360 °. It is driven by a toothed belt 20 by means of a motor 21. The bogie 19 comprises a receiving device for a paper roll 4, which comprises a centrally disposed continuous track section 22 which can receive a carriage 8 loaded with the paper roll 4. On both sides of the track section 22, the receiving device has two parallel, elongated, raised and lowered claws 23a, b, by means of which the paper roll 4 can be lifted, in particular lifted off the carriage 8.

The system is controlled by a material flow computer. During operation, the intermediate storage 1 is filled with prepared paper rolls 4 during operation. For this purpose, a packed roll of paper 4 'at the end of the ramp 7 is loaded onto a carriage 8, which brings them to the preparation station 9 via the feed track 10, where it is lifted off the carriage 8, unpacked manually and provided with a splice, that is completely prepared, while the carriage 8 moves back to the ramp 7. In the preparation of the paper roll 4 at the same time their Wickelsinn is determined and entered into the material flow computer.

Subsequently, the prepared paper roll 4 is stored on another carriage 8, which continues to takeover place 11. The storage and retrieval device 6 stands with rotated by 90 ° bogie 19 abutting on the takeover place 11 end of the web 5, so that the track section 22 is aligned with the Zuführgeleise 10. The carriage 8 moves onto the track section 22, whereupon the claws 23a, b are lifted and the paper roll 4 is lifted off the carriage 8. The carriage 8 then travels back to the feed track 10 and can later receive a prepared paper roll 4 at the preparation station 9.

Now, the winding sense of the paper roll 4 is checked by the material flow computer. Depending on the result carries the bogie 19, driven by the motor 21, a rotation of 90 ° in the counterclockwise or clockwise direction, such that the winding sense of the stored paper roll 4 then corresponds to a desired value. At the same time, the storage and retrieval device 6 is moved over the web 5 next to the provided for the paper roll 4 storage space 3, so that the track section 22 is aligned with the Lagergeleisen 12 of the proposed storage space 3 and the same opposite storage space 3 and adjoins them. Thereupon, an empty carriage 8 parked on the storage jig 12 moves onto the track section 22, whereupon the claws 23a, b are lowered and thus the paper roll 4 is deposited on the carriage 8. The carriage 8 now moves from the track section 22 of the storage and retrieval device 6 on the storage track 12 of the intended storage space 3. The process is usually repeated until the intermediate storage 1 is filled with prepared paper rolls 4.

The roll stands 15a, b, even if the work at the preparation station 9 rests, prepared as needed paper rolls 4 supplied from the intermediate storage 1. For feeding a paper roll 4 provided for about the roll stand 15a, the storage and retrieval device 6 is moved next to their storage space 3, whereupon the paper roll 4 carrying carriage 8 from the storage track 12 auflaufs on the track section 22 of the storage and retrieval device 6. By lifting the claws 23a, b, in turn, the paper roll 4 is lifted off the carriage 8, which then returns empty on the bearing track 12. The storage and retrieval device 6 is then moved next to the transfer place 13a, on which a carriage 8 is already available. The carriage 8 now moves onto the track section 22 of the storage and retrieval device 6, whereupon its claws 23a, b are lowered and the paper roll 4 is deposited on the carriage 8, which then moves back to the transfer station 13a and continues to the same or later via the supply track 14a Roller stand 15a, where he ascends on the traverser and the paper roll 4 is clamped. The empty carriage 8 is then returned to the transfer station 13a, where he remains on hold.

In a storage and retrieval device 6 according to a second embodiment (Fig. 4, 5), the receiving device also has two symmetrically and parallelly arranged elongated claws 23a, b, which can be raised and lowered. The claws 23a, b are in a basic position of the storage and retrieval device 6 (FIG. 4) above the chassis 18. The storage and retrieval device 6 can assume two transfer positions, in one of which the two claws 23a, b after one and in the other they after the the other side are shifted by a little more than the length of a paper roll 4 in its longitudinal direction, so that they project far beyond the chassis 18. The storage bins 3 point in this case, instead of wagons occupied Lagergeleise stationary storage troughs 24.

The operation of the inventive system with a storage and retrieval device according to the second embodiment is not fundamentally different from the above. Only in the recording and delivery of a paper roll by the storage and retrieval device 6 from a car or to a car, the latter does not drive on the bogie 19 of the storage and retrieval device 6 - it is also no track section provided - but he just drives next to the storage control unit 6, the then his transfer position with advanced, lowered or raised above the carriage 8 projecting claws 23a, b, which then lifted to receive a paper roll 4 from the carriage 8 or lowered to deposit a paper roll 4 on the carriage 8 and then by the storage control unit 6 again assumes the basic position, be withdrawn. In the same way, the storage of a paper roll 4 takes place on the storage tray 24 of the intended storage space 3 and the inclusion of such from said storage tray 24th

According to a slightly different from the first second embodiment of the inventive system (Figure 6) the ramp 7 is aligned in the longitudinal direction, while the Zuführgeleise 10 extends in the transverse direction and laterally abuts the web 5, where by shifting two storage bins from the series 2b in the row 2a was left room for it. The operation of this system is almost entirely similar to that described above in connection with the first embodiment. Only in the takeover of a paper roll 4 by the storage and retrieval device 6, the receiving device aligned transversely. Depending on the Wickelsinn the paper roll 4 no rotation of the Bogie 19 or a rotation through 180 °, such that the winding sense of the stored paper roll 4 again corresponds to the desired value.

If the setpoint value of the winding direction for the paper rolls 4 is independent of the type of use, the paper rolls 4 can be stored in the intermediate store 1 consistently with the same, corresponding to the setpoint Wickelsinn, which increases the clarity and facilitates the management of the intermediate storage 1. Of course, it is also possible in any case to store the paper rolls disorderly in this regard and only when the paper roll, by rotation of the bogie 19 of the storage and retrieval device 6 by 180 ° where necessary to bring the winding sense of the paper roll with the setpoint in accordance.

The intermediate storage 1 can also (Fig. 7) as a high-bay warehouse with two - u.U. Also more - rows 2 a, b of bearing troughs 24 equipped storage bins 3 to be formed one above the other. In this case, the storage and retrieval device 6 has a lifting device, which is arranged on the bogie 19 and, e.g. is designed as a scissors cross 25 and which carries the receiving device, so that the same over an adjustment range, which covers the lower and upper row, that extends over more than the diameter of a paper roll, is adjustable in height. The receiving device can be designed as described in connection with the second embodiment of the storage and retrieval device 6.
