Abstract

Roller changing device of a web-fed rotary printing machine, comprising a) a roll changer, b) a first transport carriage (7) for at least one resting roller c) and a second transport carriage (8, 9) for at least one resting roller, preferably residual roller, d) the first transport carriage ( 7) of the second trolley (8, 9) can be at least partially run over.

Description

at a first known solution are the Rollenübergabeplatz and the residual roll container, towards the machine axis seen in a row. The disadvantage of this solution, that by the separate transfer places on the Loading page high demands on the position of the building pillars be put.

at a second known solution is the removal of the residual roll container from the roll transfer station opposite side. The disadvantage is that the two-sided Access to the reel splitter is necessary, on the one hand for the load of paper rolls, on the other side for the removal of the residual roll container.

at a third known solution is the first trolley parked in a separate rail section, so that the second trolley with the residual roll container up to the transfer point can drive.

A The object of the invention is a residual role recording on to provide a feed side of the roll changer such that they even in the presence of building pillars automatically taken over by mechanical means and by the Reel splitter removed, for example, to the waste collection point can be brought.

One first trolley, preferably trolley, stands for the paper roll transport preferably on a guideway, For example, in a branch channel, available. With a second trolley, preferably trolley, a residual role recording, For example, a roll container, preferably longitudinally transported the same guideway. The dolly become representative of alternative trolley systems hereinafter referred to as trolley. In providing the Rest roll holder for automatic removal on the transfer station the second trolley goes over at least partially the first trolley.

New is the at least partially driving over the first trolley through the second. The second dolly crossing the first transport vehicle preferably into a transfer position, in which one transported by means of the second trolley Restrolle seen in the longitudinal direction of the guideway occupy the same position as a new role of the same length, the alternative to the remaining role on the first dolly transfer position can take.

By at least partially driving over the first trolley By the second trolley can disadvantages of the known Systems are overcome, and there is a system for Available, with the same guideway, preferably linear axis, both the paper roll and the remaining role recording to provide at the transfer point. By the inventive system It is possible, even with unfavorable construction Conditions to completely automate the material flow.

In a first variant, the roller changing device has a puncture channel or a differently formed guide track with preferably at least three, particularly preferably exactly three sections driven independently of one another, such as in the US Pat EP 0 587 015 described. The sections are called "Track Roller", "Track Slide Deck" and "Track Tray".

One first trolley for paper roll transport runs in the sections "Track Roller" and "Track Slide Deck". This first trolley has, for example, a prismatic above-ground geometry, which serves as a pad for a new role, and has his starting position at the transfer point at the end of the "rail role".

One second trolley carries the Restrolleaufnahme and wrong in preferably all three rail sections: For automatic Take-up of a residual roll after a roll change only in the sections "rail containers" and "rail transport platform" the rest of the roll support on the transfer station in addition also in the "rail roll." When not in use is the second trolley stationed in the "rail container" may be formed, for example, as a support on which the remaining roll just simply rests with their weight and preferably by itself centered.

Of the second trolley is overfloor with a platform for equipped the recording of the residual role recording. This platform is preferably asymmetric to make it the first Can overtop trolley. The residual roll receptacle is preferably designed such that they by means of an adjacent means of transport lifted off the platform and to the central collection point for Restrolls can be brought. Thus the relative position between the Restrolleaufnahme and the platform always guaranteed is, the remaining roll intake can advantageously Zentnerelemente exhibit.

Due to an asymmetric position of the residual roll receptacle on the second trolley, a tilting moment can arise. The guide systems are generally not able to absorb the corresponding tilting moment due to lack of accuracy. Preferably, the second trolley Therefore, by means of support and preferably guide elements, such as rollers, stabilized, namely supported and preferably guided laterally. With the help of the support elements whose distance is transverse to the direction of movement, in the case of rolls, this is the gauge, preferably larger than the width of the first trolley, the tilting moment is derived to the ground, preferably a cover of the guideway. Preferably, a guide element or pair of guide elements, preferably pair of rollers, arranged such that the second trolley laterally centered when approaching the first trolley and thereby aligned axially parallel to this.

For the inclusion of a residual role in the residual roll container or the otherwise formed residual role recording is the exact axis-parallel Alignment immaterial, so be for this process only the support elements, but not the Zentnerelemente needed. The centering elements are preferably rollers.

Should the residual role recording provided on the transfer point be, affects their axis-parallel alignment to the guideway the process security. Only then can it be ensured that the load-carrying means of the adjacent means of transport, such as for example automated guided vehicle systems (FTS), warehouse operators (LBG) or crane systems, the residual role recording properly can record.

Around to drive the remaining roll holder onto the transfer station, the first trolley is placed in such a way, preferably at the end a rail section that the second trolley on the first Trolley can move. Is the gauge of the support elements greater than the width of the first trolley, can These pass the Überflurteil the first trolley. The centering elements have a distance that is only slightly greater than the width of the first trolley. About inlet slopes the first trolley are the centering of the second trolley placed in the correct position and make an axis-parallel alignment the second trolley with the residual role recording safe.

Short before the two trolleys touch, the drive becomes the rail section in which the first trolley is located, switched on. Now both trolleys move synchronously in the direction of the transfer station until the first trolley hits an end cushioning. By briefly running the drive of the rail system is ensured that both trolleys are close together and the second trolley at least partially over the first trolley pushed.

Through the use of single-wheeled trolleys, such as in the EP 140 472 described, the construction would be simplified, since the first trolley can be run over at any point by the second.

A alternative embodiment is for the Guideway, preferably guide channel, a to use more accurate guidance system, which is both the axis parallelism as well as the moment support of the second trolley ensured. Because of the high mass that needs to be transported, this would be but expensive.

The inventive system can in particular for Collecting and transferring so-called residual rolls of rotary printing presses, to an adjacent transport system, be used.
