Abstract

The invention concerns an installation storing several rolls used to convey prepared rolls to a roll changer (2).

Description

Procedure for transporting rolls to a roll changer

The invention relates to a method for transporting rolls according to the preamble of claims 1 and 7.

DE 36 27 454 A1 discloses a generic method for transporting rolls to a roll changer. Here, a roll provided with adhesive is loaded directly onto a transport trolley which carries this prepared roll until this roll has been raised on the tensioning cones of the roll changer.

DE 39 10 444 A1 describes a system for supplying and removing rolls to roll changers with an intermediate store. Each of these roll changers is assigned its own gluing station.

The disadvantage here is that a large number of K Lebestat ions is necessary.

The invention has for its object to provide a method for transporting reels to a reel changer.

This object is achieved by the features of the characterizing part of claims 1 and 7. The advantages that can be achieved with the invention consist in particular in that a prepared roll provided with adhesive remains on a transport trolley assigned to it from a preparation station to a roll changer without reloading. Damage to the prepared roll is thus avoided and disruptions when changing rolls are minimized. It is advantageous that a plurality of rolls provided with adhesives are stored in an intermediate store, as a result of which a preparation station can be assigned to a plurality of roll changers. In this warehouse, various types of prepared rolls (e.g. roll width, grammage, etc.) can be stored on separate tracks assigned to them, which can then be removed selectively. This increases the flexibility of the reel changer while reducing the number of preparation stations.

The system according to the invention for the transport of rolls is shown in the drawing and is described in more detail below.

Fig. 4 is a schematic side view of a Rol lenwechsel lers.

A system for the automatic transport of rolls 1 from a store to roll changer 2 of a rotary printing press is constructed as follows: from a monthly store 3, the standing rolls 1 are transported by a stacker 4 to a non-visible left roll surface and lying thereon (i.e. with a longitudinal axis) roll 7 almost horizontally). From this rolling surface, the rollers 1 are brought onto a first apron conveyor 6. This plate belt conveyor 6 transports the lying rolls 7 to a first unpacking station 8 by means of the end covers of the rolls 7. The first of these first unpacking station 8 conveys Plate conveyor 6 the rollers 7 to a second unpacking station 9. This second unpacking station 9 removes a peripheral packaging of the rollers 7 and swivels these lying rollers 7 in a horizontal plane by 90 °. These rolls 11 are placed on a second plate belt conveyor 12 running parallel to the transport direction of the web-fed rotary printing press, and with their longitudinal axes in the longitudinal direction of the web-fed rotary press to two transfer stations 13; 14 t transport.

A between the transfer stations 13; 14 and the reel changer 2 of the web-fed rotary printing press part of the system for transporting reels 11 is constructed symmetrically in the present exemplary embodiment, which is why only the right half is described below for the sake of simplicity.

The transfer station 13 pushes the rollers 11 onto a transport trolley 16. Such transport trolleys 16, which are known per se, are, for example, rail-guided. The transport carriage 16 has four rollers 18 which roll on a pair of rails 17. Instead of one of a pair of rails 17, a single rail can also be provided. The term "track" used in the following includes both a single rail and a plurality of rails running in parallel. To drive this transport carriage 16, for example, an underfloor drag conveyor is provided, which in the present exemplary embodiment is designed as a revolving chain. With this chain is the dolly 16 at least temporarily connected. On a frame 19 of the trolley 16 z. B. attached a trough-like shell for receiving the roller 11. This receptacle 21 in the form of a shell protrudes from a floor 22 of the storage room, while the transport carriage 16 runs largely sunk in the floor 22 of the storage room.

In the embodiment, the transport trolley 16 stands on a turntable 23 which can be pivoted by at least 90 °, preferably 360 °, during loading from the apron conveyor 12 to the transport trolley 16. This turntable 23 has guides which intersect at 90 ° , e.g. B. rail pieces for receiving the trolley 16. After the trolley 16 is loaded with the roller 24, the trolley 16 is transported with the roller 24 to a preparation station 26. In this preparation station 26, the roll 24 is raised by two take-up rolls running parallel to the longitudinal axis of the roll 24, and a beginning of the roll 24 is prepared with live strips and refector strips for a roll change.

After this adhesive preparation, the roller 24 is lowered onto the waiting trolley 16. This transport carriage 16, which is now loaded with a roll 24 prepared for the roll change, is loaded onto a second transport carriage 27. This second transport carriage 27 is also underfloor, for example, in the longitudinal direction of the Roll rotary printing machine running, provided with track-guided rollers. On this second transport carriage 27 is a turntable 28 with at least one receptacle 29, for. B. attached a rail piece. Also, as shown in the example, intersecting recordings 29, z. B. track pieces possible. The second transport carriage 27 travels to a selected track 31 of a plurality of tracks 31; 32; 33; 34; 36; 37; 38; having intermediate storage 39. On the way between the preparation station 26 and the selected track 31 of the intermediate storage 39, the loaded transport carriage 27 with the roller 24 is pivoted by 90 ° in the direction of the selected track 31 by means of the turntable 28 of the transport carriage. In front of the selected track 31 of the intermediate storage 39, the transport carriage 27, which runs in the longitudinal direction of the web-fed rotary printing press, positions the loaded transport carriage 16, which carries the roll 24, so that it can move directly into this track 31. The transport carriage 16 carrying the roller 24 is now moved into the selected track 31 and parked. In this way, a plurality of tracks 31; 32; 33; 34; 36; 37; 38 of the interim storage facility 39, transport trolleys 16 loaded with prepared rollers 24 are temporarily stored.

In the illustrated embodiment, the length of a track of the intermediate store 39 is designed so that, for example, three loaded with one roller 24 each Transport carriage 16 in a selected track 31; 32; 33; 34; 36; 37; 38 can be parked. Half of the intermediate storage 39 has seven tracks 31; 32; 33; 34; 36; 37; 38 on, each of which can accommodate three trolleys 16.

A third transport carriage 41 is provided for further transport to the roll changer 2. This transport carriage 41 can be moved in the longitudinal direction of the web-fed rotary printing press and has at least two receptacles 42; 43 on. These receptacles 42; 43 are spaced such that at least one residual roller 44 with a reduced diameter d44 and a prepared roller 24 with a maximum diameter d24 can be accommodated at the same time. The distance between the two centers of the guides 42; 43 to understand.

This transport carriage 41 is positioned in front of one end of a selected track 31; 32; 33; 34; 36; 37; 38 of the intermediate storage 39, so that a transport carriage 16 loaded with a prepared roller 24 can move directly into this transport carriage 41. This dolly 41 travels to a preselected roller changer 2.

Before the transport to the intermediate storage 39, each roll 24 is prepared for glue, ie that from the Intermediate storage 39 in the direction of roll changer 2 roller 24 is prepared before removal from the intermediate storage 39, ie provided with adhesives. The intermediate storage 39 thus stores a plurality of these transport carriages 16, each loaded with a prepared, ie provided with adhesive 24 roll. From this intermediate storage 39, a roll 24 to be fed to the roll changer can be selected.

In particular, a track 31; 32; 33; 34; 36; 37; 38 of the intermediate storage 39 can be selected. All "new" rolls stored in the intermediate storage 39 are prepared before removal and supply to the roll changer.

Each of these reel changers 2 has two tracks 46 running parallel to one another and perpendicular to the longitudinal direction of the web-fed rotary printing press; 47 assigned. The track 46 nearest the corresponding reel changer 2 preferably serves to receive the reel 24 to be fed. These two tracks 46 leading from a side 48 facing the intermediate storage 39 into the reel changer 2; 47 can, as in the exemplary embodiment, also extend beyond the side 49 of the web-fed rotary printing press facing away from the intermediate storage 39. The extended ends of the tracks 46; 47 are only accessible from reel changer 2, ie these ends are "dead ends"51; 52 executed. On this beyond the side frame of the reel changer extended dead ends 51; 52, as shown, a transport trolley 16 with a prepared roller 24 or with a residual roller 44 can be temporarily stored.

The second track 47 assigned to the roller changer 2 serves to transport a transport carriage 16 with a residual roller 44 with a reduced diameter D44 from the roller changer 2 to the transport carriage 41 which can be moved in the longitudinal direction.

This transport carriage 41 positioned in front of the selected reel changer 2 such that the two receptacles 42; 43 of the transport carriage 41 with the two tracks 46; 47 are cursed. It is thus possible for this transport carriage 41 from both tracks 46; 47 to load and unload without changing its position.

From this transport carriage 41, the transport carriage 14 with the prepared roller 24 is moved into the track 46 and temporarily stored or fed directly to the roller changer 2. On the second track 47 there is already a second transport carriage 16 in a parking position with an exchanged remaining roller 44, which for example has only one roller core 53 or at least a reduced diameter d44. This transport trolley 16 loaded with the exchanged residual roller 44 travels during or after unloading of the transport trolley 16 loaded with the prepared roller 24 onto the third transport trolley 41 which can be moved in the longitudinal direction. To change the roll, the transport carriage 16 loaded with the prepared roll 24 moves onto a fourth transport carriage 54 which can be moved in the longitudinal direction of the web-fed rotary printing press. This transport carriage 54 is located between side frames 56; 57 of the roll changer 2 can be moved, arranged under the floor and has a receptacle 58. This receptacle 58 is parallel to the two tracks 46; 47 and thus aligned parallel to an axis spanned by clamping cones 59 of the roller changer 2. The transport carriage 54 can be positioned so that its receptacle 58 in a first position, a feed position "Z", cooperates with the first track 46, in a second position, a parking position "P", with the second track 47 and in a third position, a removal position "A", under which the worn out residual roller 44 carrying arm 61 is. Starting from the feed position "Z", the transport carriage 54 with the loaded transport carriage 16 moves the prepared roller 24 into an exchange position. This change position is dependent on a swivel radius r59 of the clamping cones 59 of the reel changer 2 and on the diameter d24 of the prepared reel 24.

In this changing position, the on the two trolleys 54; 16 located roller 24 gripped by the two clamping cones 59 of a support arm 62 of the two-armed reel changer 2, for example. This support arm 62 pivots with the gripped roller 24 for gluing up.

After the reel changer 2 has gripped the new reel 24 and lifted it off the transport carriage 16, the longitudinally movable transport carriage 54 moves under the second support arm 61, which has an expired residual roll 44. This support arm 61 stands on the first support arm 62 during the gluing process of the new one raised roller 24 approximately vertically, so that a distance between the empty receptacle 21 of the trolley 16 and the unwound residual roll 44 is minimal or only slightly larger than the smallest distance. The tensioning cones 59 of the roll changer 2 now release the expired residual roll 44. This expired residual roll 44 falls on the receptacle 21 of the transport carriage 16.

The trolley 54 loaded with the expired residual roll 44 and the trolley 16 moves out of the roll changer 2 into its parking position "P".

During the roll change process, the third transport carriage 41, which can be moved in the longitudinal direction and is loaded with the transport carriage 16 carrying the remaining roll 44, moves to a selectable track 63; 64; 66 of the interim storage facility 39. In front of this selected track 63; 64; 66 positions the transport trolley 41 so that the loaded transport trolley 16 carrying the remaining roll 44 is in this track 63; 64; 66 can retract. With this selected track 63; 64; 66 can be, for example, a track 63; 64 act for the intermediate storage of the partially expired residual rolls 44 with the assigned transport trolleys 16. In the exemplary embodiment, two of these tracks 63; 64 provided for intermediate storage and for re-feeding to the reel changer 2.

In most cases, the trolley 41 loaded with the expired residual roll 44 moves into a track to which an unloading station 67 is assigned, which removes the expired residual roll 44 from the transport trolley 16.

This provided for unloading track 66 opens in the embodiment on the upstream of the U loading station 13 or 14 turntable 23. The now empty transport carriage 13 is fed to this turntable 23 and pivoted by 90 °, so that this transport carriage 16 can be reloaded.

The transport carriage 16; 27; 41; 54 can also be used as a "driverless" trolley, i.e. as an "Automated Guided Vehicle" (AGV).

It is also possible not to use these trolleys under the floor, but as a monorail. Reference list
