Method of storing rolls of material

The invention relates to methods for storing material rolls according to claim 1 or 10.

DE 39 10 444 C2 discloses a device for supplying material to a system, in particular a printing press, with rolls being temporarily stored in a buffer store. The warehouse has two shelf blocks, between which a stacking device is provided, which is designed to operate both shelf blocks.

DE 100 57 735 A1 discloses a system for picking articles with a plurality of parallel rows of racks, with storage and picking aisles alternating between the rows of racks.

A storage system is disclosed by DE 21 58 537 A, storage spaces of a middle row of shelves being operable from corridors adjoining on both sides.

DE 37 38 052 A1 discloses a storage and provisioning system for processing goods of a production line, the shelves being divided into preparation and storage areas and storing the goods and relocating or relocating them from the storage area into the preparation area or into others Shelf aisles are guided by process computers.

The invention has for its object to provide methods for storage-optimized storage of prepared and unprepared rolls of material.

The object is achieved by the features of claim 1 or 10. The advantages that can be achieved with the invention are, in particular, that the bearing ensures high flexibility and a supply even during peak loads. The storage space to be kept is optimized.

A design of several shelf blocks that overlap in the longitudinal direction, at least in some areas, enables both unprepared rolls to be delivered, regardless of the production process, as well as quick passage of prepared rolls into a shelf block closer to the printing press.

The design of an internal shelf block as accessible from both long sides enables the rolls to be moved very efficiently between the individual blocks. The loading and unloading of a roll from an inside shelf block is not tied to an operating device of an aisle, so that the shelf block can be loaded from one side, while at the same time removal can take place from the other side. Bypassing a bearing block and thus a mutual hindrance of different operating devices can be avoided.

Embodiments of the invention are shown in the drawings and are described in more detail below.

A web processing and / or processing company, e.g. B. a printer according to FIG. 1, z. B. at least one web processing and / or processing machine 01, z. B. printing machine 01, a material supply system 02, z. B. role supply system 02, and possibly a product planning system 03. It also has z. B. via a control system 05 designed as a material flow system 05 for coordinating and ensuring the supply of production with rolls. The product planning system 03 has information on the set-up of the machine and / or on the roll requirement for a certain planned production, or even a production plan going further into the future, from which the future roll requirement (paper type, quantity, dimensions) can be derived.

The printing press 01 has at least one unit 04 designed as a printing unit 04 and / or printing tower 04 for printing on a web, which is provided by at least one unit 06 designed as a roll changer 06 (standstill roll changer or roll changer for the roll change at full machine speed) with material, e.g. B. paper is supplied. Furthermore, the printing press 01 can have a unit 07 arranged downstream of the printing unit 04 for processing the printed web, e.g. B. include at least one folder 07. The at least one printing unit 04, the at least one reel changer 06 and possibly the at least one folder 07 are e.g. B. via at least one signal line 09, z. B. a press internal network 09, with at least one operating and computing unit 08, z. B. a control center with PC, connected.

For a production i. d. Usually several (e.g. five or more) reel changers 06 are brought together on a folder 07. This combination with the associated printing units 04 or printing towers 04 is called Section A; B designated. A machine line exists e.g. B. from several sections A; B, on which different productions can be run.

In the example shown in FIG. 1, the printing press 01 exemplarily has two sections A; B with two printing towers 04, three reel changers 06, three operating and computing units 08 and one folder 07 per section A; B on. 1, the reel changer 06 and the printing units 04 of each section are, for. B. connected via the network 09. There is over network 09 (homogeneous or heterogeneous) between sections A; B and / or the operating and computing units 08 a connection. The folders 07, if available, are z. B. with this network 09 in connection.

The operating and computing units 08, together with their cross-connection and any other computing and data processing units that are present but not shown, form a so-called control level 11 or machine control level 11 of the printing press 01. B. in signal connection 12 with z. B. at least one computing and / or data processing unit 13 of the product planning system 03. Via this signal connection 12, for example, production-relevant data are transmitted from the product planning system 03 to the printing press 01.

In one embodiment, the printing press 01 is e.g. B. in a suitable manner, for. B. on the material flow system 05, in signal connection 15; 16 with the roll supply system 02. Production-relevant data can be transmitted from the printing press 01 via at least the signal connection 16 between the printing press 01 and the material flow system 05 the material flow system 05 are transmitted, for. B. logic implemented there for (partial) processing of one or more of the processes explained below for FIG. 4. For this purpose, the material flow system 05 has at least one computing and / or data processing unit 17 that houses the implemented logic.

In addition or as an alternative to the signal connection 16, a transfer can also take place via an optional signal connection 20 from the product planning system 03. If available, the material flow system 05 can, in principle, also be assigned to the roll supply system 02 or the printing press 01 or, in an advantageous embodiment, can be superordinate to these two - within the scope of its tasks.

A possible hardware configuration of a roll supply system 02 is shown schematically in FIG. 2, although not all of the subsystems described below need to be present in a device and / or for the procedure according to the invention, and the individual functional subsystems can be embodied in a different way than shown.

In the exemplary embodiment according to FIG. 2, the roll supply system 02 has z. B. at least one goods receipt 18, a first transport system 19, and at least one warehouse 21.

The bearing 21 has in the longitudinal direction next to one another at least three, at least partially overlapping shelf blocks 22; 23; 24, with an outer shelf block 22 lying away from the roll changers 06, a shelf block 23 closest to the roll changers 06 and an inner shelf block 24 lying between the two shelf blocks 22 and 23. As shelf block 22; 23; 24 here is an arrangement of adjacent storage locations 26; 27; 28 (in FIG. 2 only one storage location 26; 27; 28 per shelf block 22; 23; 24) to understand which can take up a role next to each other and / or one above the other.

The middle shelf block 24 is now designed in such a way that at least in one area a storage location 28 assigned to it can be operated from both long sides of the shelf block 24. For this purpose, the shelf block 24 in an advantageous embodiment in this area has only one storage space 24 in its width.

If several storage spaces are to be provided in width, care must be taken to ensure that only one of the storage spaces arranged one behind the other is occupied in the area provided (for the purpose at hand here) and that an operating device has the appropriate range to cover an empty storage space to move a role.

Between each two shelf blocks 22; 23; 24 are longitudinally extending spaces, for. B. corridors, which each have at least one transport system 29; 30, e.g. B. a stacker crane 29; 30, is assigned. The between two shelf blocks 22; 23; 24 arranged storage and retrieval machines 29; 30 are preferably designed so that they are in storage bins 26; 27; 28 of both adjacent shelf blocks 22; 23; 24 can access. The storage and retrieval machines 29; 30 are preferably designed such that a tool which interacts with the rollers has at least one degree of freedom in the horizontal direction along the corridor, in the vertical direction and in the horizontal direction transverse to the corridor.

The transport system 19 has at least one transport route 31 from the delivery to the warehouse 21. In particular, at least one transport path 31 to a storage location 32 of the outer shelf block 22 is provided, which, for. B. serves as a transfer station 32 during storage or is configured. In a preferred embodiment, the transport system 19 additionally has at least one transport route 33 to a storage location 34, e.g. B. as a transfer station 34, the inner shelf block 24. For this purpose, the outer shelf block 24 has access, for example a feedthrough, or the outer shelf block 24 does not extend over the same length of the inner shelf block 24 as is the case in the exemplary embodiment according to FIG. 2. Coming from the incoming goods, e.g. B. roles not yet prepared can thus be stored either in the outer shelf block 22 or in the inner shelf block 24.

In an advantageous embodiment, the transport system 19 additionally has at least one transport path 36 via a so-called preparation circuit 35, which from the goods receipt 18 z. B. via an unpacking station 37 and / or an adhesive preparation 38 to a storage location 39, z. B. leads as a transfer station 39, the inner shelf block 24. Again, for example, an above-mentioned Implementation or a shortening of the outer shelf block 22 is provided.

In a further development, transport routes 31, 33 and / or 36 are connected to one another in such a way that a roll that has already been prepared by the unpacking station 37 and / or the adhesive preparation 38 can be moved to the storage space 32 of the outer shelf block 22.

In an advantageous development, the transport system 19 has at least one transport path 41 different from the transport path 32, on which rollers from a storage location 42, e.g. B. as a transfer station 42 of the outer shelf block 22 again on transport routes 31; 33; 36 of the transport system 19 can be taken over. An stored, unprepared roll can thus be removed again and prepared via the transport path 36 and fed to the inner shelf block 24.

Likewise, in an advantageous further development, the transport system 19 has at least one transport path 43 different from the transport path 33 or 36, on which rollers from a storage location 44, e.g. B. as a transfer station 44, the inner shelf block 24 again on transport routes 31; 33; 36 of the transport system 19 can be taken over. An unprepared roll stored in the inner shelf block 24 can thus be removed again, for example, and prepared via the transport path 36 and in turn fed to the inner shelf block 24.

The operating device 29 arranged between the outer shelf block 22 and the inner shelf block 24 now takes over, for example, the role delivered to the storage location 32 and stores it e.g. B. to a free storage space 26 of the outer shelf block 22 around. As a rule, the outer shelf block 22 has only unprepared roles. However, in exceptional situations it can also serve as a buffer for roles that have already been prepared. This can e.g. B. be the case if a long production break was used for preparation and / or a large production is planned.

If there are certain logistical reasons or if the outer shelf block 22 is already fully equipped with unprepared roles, the operating device 29 takes over the delivered, e.g. B. unprepared role and stores it in a storage space 28 of the inner shelf block 24. The inner shelf block 24 serves as a buffer for unprepared roles. For the purpose of preparation, these can then be fed by the operating device 29 from the storage space 28 back to the transport system 19, and thus to the unpacking station 38 and / or the adhesive preparation 38, via the storage space 42 of the outer shelf block 22.

The operating device 30 arranged between the inner shelf block 24 and the outer shelf block 23 closest to the roll changer 06 is also designed to operate both adjacent shelf blocks 23; 24 to use. It now takes over, for example, a role that has already been delivered to storage location 39 and stores it, for example. B. to a free storage space 28 of the inner shelf block 24 around. The inner shelf block 24 can contain both prepared and unprepared rolls, according to the above statements. However, it can also only have prepared roles if, for. B. planned a large production is. In exceptional situations, only unprepared rolls can be stored if, for example, a longer production break is imminent and / or a correspondingly large delivery has taken place.

By means of the operating device 30 unprepared roles can now be stored from the storage place 34. B. relocate to a free Lageφlatz 28 of the inner shelf block 24 or to a free Lagβφlatz 27 of the roller changer 06 next shelf block 23.

If there are certain logistical reasons, unprepared roles from the inner shelf block 24, e.g. B. from Positionφlatz 34 or a Lagβφlatz 28 in the roller changer 06 next shelf block 22 for buffering.

Basically, however, the inner shelf block 24 serves to buffer prepared and unprepared rolls, so that preferably only unprepared rolls are stored in the outer shelf block 22 removed from the roll changer 06, and only prepared rolls are stored in the shelf block 23 closest to the roll changer 06. The outer bearing block 22 together with parts of the inner bearing block 24 thus functions as a main bearing, and the shelf block 23 closest to the reel changer 06 together with parts of the inner shelf block 24 serve as a so-called day storage.

A further transport system 46 is provided between the outer shelf block 28 and the roll changers 06, by means of which rollers can be removed from the shelf block 23 and fed to the or one of the roll changers 06. The transport system 46 can in principle in any way, for. B. with forklifts, with driverless transport systems "(AGVS), rail-bound or frosted vehicles, manned or unmanned, be executed. However, it is advantageous if it is driverless and designed by a higher-level control and / or control system, eg. B. by the Mate alflus system 05, or its associated reel changer 06 Receives orders.

In the example, each reel changer 06 has an inner loading circuit 47, z. B. associated rail-bound transport wagons with corresponding guides. These transport systems

47 are in the shelf block 23 for transfer or submission serving storage spaces 48, z. B. template position 48 assigned.

In the above-mentioned embodiment with a template space 48 defined for each reel changer 06, the operator control 30 presents the reels required or requested for the respective reel changer 06. These can be found in the storage locations 27 of the shelf block 23 or in the location positions 28 of the inner shelf block 24. In special cases, the control unit 30 can also take a roll directly from the transfer location 39 and deliver it to the template location 48.

In an embodiment not shown, the required roll can also be removed by a transport system 46, the transport then taking place, for example, using a transport means that is not assigned to a single roll changer 06 (for example a manned forklift or an AGV). In this case, there may also be no fixed template places

48 can be defined for the individual reel changers 06. In an embodiment of this type, a means of transport can then be used, for example, from one of the various storage locations 48 intended for presentation. If, in a further development, all or some of the locations 27 are accessible from both sides, the roles corresponding to the requirements can be taken directly from the means of transport from the shelf block 23.

The control devices 29; 30 are preferably as shown in FIG. 3 as storage and retrieval devices 29; 30 executed. A gripping and / or lifting mechanism 51 is arranged on a vertical mast 52 in the manner and driven that it in the vertical direction from a position of a lowest level E1 of the respective shelf block 22; 23; 24 is movable up to a storage location of a top level E11. The carrier 52 is mounted and driven in the lower region and in the upper region of the bearing 21 in such a way that it can be moved horizontally in the longitudinal direction of the corridors. The gripping and / or lifting mechanism 51 is in turn movable and driven relative to the carrier 52 by rotation and / or a linear movement in the horizontal direction in such a way that it rolls from the two adjacent shelf blocks 22; 23; 24 can take up or put roles there. In FIG. 3 it can also be seen that the width of the inner shelf block 24 is only a single layer 28; 34; 39, 44, which from both sides of the shelf block 24 by the respective control device 29; 30 is accessible.

When selecting a role or the location location 27 or 28 by the operating device 30 and the subsequent presentation at the storage location 48, geometric and / or quality requirements for the desired role are taken into account. This also applies to the example, not shown, with direct access to the storage bins 27 by an alternative transport system 46.

For this purpose, i.e. the exact knowledge of the current occupancy of the storage bins 26; 27; 28; 32; 34; 39; 48 together with the specific role properties, it is advantageous to provide at least one warehouse management system in which the location locations 26; 27; 28; 32; 34; 39; 48 of the roles, with the corresponding properties, are carried. For this purpose, in an advantageous embodiment, corresponding role data are recorded in the area of the goods receipt (or possibly in the area of the role preparation) and assigned to the role. The warehouse management system then always has information on the allocation of the warehouse 21 with the specific roles.

In a particularly advantageous embodiment, the warehouse 21 (with warehouse management system), the goods receipt 18 and at least the outer, ie the transport systems 19 located outside the warehouse 21; 46 integrated into a material flow system 05, which is connected to the control level 11 and / or the product planning system 03. Are the operating devices 29; 30 is not commissioned by a warehouse management system, the function of warehouse management and the assignment of orders to the operating devices 29; 30 may also take place through the material flow system 05.

Due to the integration into a material flow system 05, a particularly effective material management, an optimized storage in the shelf blocks 22; 23; 24 and an efficient delivery to the reel changer possible.

The material supply system 02 described, the formation of the bearing 21, for. B. in conjunction all or some of the named transport routes 31; 33; 36; 42; 43, is of particular advantage in connection with printing presses 01, which have several sections A; B has. In particular, the material supply system 02, or the design of the bearing 21, is advantageous if a plurality of printing presses 01 are arranged one behind the other in the manner of a printing press system, as is shown in FIG. 2.

The bearing 21 extends over the entire length of the two 'printing presses 01. The shelf block 23 closest to the roll changers 06 extends essentially over the entire length from the first to the last roll changer 06. In the example, the inner shelf block 24 extends over the same length. In order to allow direct access from the goods receipt 18 to the inner shelf block 24, the outer shelf block 22 closest to the goods receipt 18 is made shorter. This is essentially symmetrical to the two printing presses 01 to be supplied. In the example, the material supply system 02 has two areas for the goods receipt 18, which are each connected via a transport system 19 to locations 32 in the near-end areas of the shelf block 24. In the hallways between two shelf blocks 22; 23; 24 are a plurality of operating devices 29; 30 provided. The embodiment of the bearing 21 shown, in particular i. V. m. of the printing press system enables a particularly flexible supply of the printing presses 01, since not only a buffer function is achieved with the inner shelf block 24, but also a printing press 01 can be supplied with rolls from an area of the bearing 21 which is at the level of the other printing press and vice versa.

In principle, a plurality of inner shelf blocks 24 can also be provided, each of which then has only one layer in its width. Between each two shelf blocks 22; 23; 24 is then an operating device 29; 30 arranged.

In the simplest case, the goods receipt 18 consists of a transfer position to the automatic roll supply and an input option for the roll receipt information. Optionally, however, it is advantageous not to unload trucks, trains or ships using the forklift but to automate them. Three fundamentally different models can be distinguished here: a) horizontal transport of the paper rolls and roll of the rolls over the circumference; b) standing transport of the paper rolls on a truck / rail wagon / ship with floor rails; c) Standing transport of the paper rolls on a special truck / rail wagon / ship, which have a kind of conveyor belt on the loading area.

A role separation can be assigned to goods receipt 18. In particular, half and quarter width rolls are usually transported standing one above the other. In this case it is necessary to separate the roles, i.e. lift the upper roll and place it next to the lower one etc.

In an automatic system, an accident can occur if it closes Transporting goods do not correspond to the expected form. It is therefore expedient to check compliance with the outer shape within certain tolerances and to additionally assign a contour control to the goods receipt 18. In the case of paper rolls, systems with light barriers, light grids or surface scanners are available, to which a more or less intelligent evaluation is connected.

Furthermore, it is advantageous if the delivered roll in the area of the goods receipt 18, for example via a barcode detection, eg. B. barcode reader 53, or another system is identified. The barcode label is used to identify the role and is recorded by the system.

The bearing 21 is, for. B. for lying storage of prepared or unprepared roles in several levels E1 to E11 executed as a high-bay warehouse 21. In principle, the high-bay warehouse 21 can also be able to accommodate pallets or standing rollers. Are the roles in the main camp 21, however. B. stored upright, at least either the control devices 29; 30 or the transport system 46 enable the roll to be tilted, or a tilting station is arranged between the bearing 21 and the roll changer. '-

A preparation circuit 35 generally has the unpacking station 37 and the adhesive preparation 38, for example, which is designed as an automatic adhesive preparation machine. In addition, there may be transfer positions in the transport system 19. The unpacking station 37 has e.g. B. a means on which the paper rolls can be aligned and unpacked semi-automatically. In addition, the barcode, e.g. B. using a hand scanner, for inspection, the diameter is determined and the roll is weighed for control. The glue preparation 38 represents, for example, an automatic glue preparation system. B. Prepare approx. 15 rolls per hour. When filling the warehouse 21, in particular the shelf block 23 and parts of the shelf block 24 with prepared rolls, it should be noted that the adhesive preparation may only take a limited time, currently e.g. B. 8-12 hours, is stable and then must be renewed. In the warehouse 21, residual rolls on loading aids that have been returned by a roll changer 06 and loading aids may also have to be handled.

A reel changer 06 has z. B. two pairs of support arms, for receiving paper rolls. Each roll changer 06 is assigned a piece of conveyor line on which a paper roll for the roll changer 06 can be presented. The reel changer 06 with its puff position (feed station) is then z. B. also referred to as the inner feed circuit 47 and is part of the printing press 01 or assigned to it. It is used for unrolling the paper rolls and for automatic roll change with adhesive.

For transport over longer horizontal distances, such as B. between goods receipt 18 and warehouse 21, z. B. plate or belt or plate conveyor used that work similar to a conveyor belt. For distance transport between goods receipt 18 and warehouse 21 or between warehouse 21 and printing press 01 z. B. also designed as driverless industrial trucks drinking systems 19; 46 can be used. However, it is advantageous within the preparation circles 35 and in the inner loading circles 31 rail-bound transport systems 19; 46, e.g. B. driven rail-bound trolleys with appropriate guides used. In small to medium-sized plants, the entire roller transport can also be carried out using rail-bound transport trolleys.

The movement control of the transport systems 19; In an advantageous development, 46 takes place in each case by means of a transport system 19; 46 assigned control, z. B. a programmable logic controller, in particular a configurator PLC (including control panel with which travel orders can be configured), or in advantageous embodiment by a transport system 19; 46 assigned computing unit, e.g. B. a vehicle control computer.

The roller supply system 02 should be capable of a printing press 01 or printing press system with one or more machine lines, each consisting of several sections A; B can exist to supply sufficient and timely with prepared paper rolls. It is also desirable that the roll supply system 02 is able to process roll requests and return orders from roll changers 06. Ideally, it is able to determine the current paper requirement, e.g. B. also to be determined on the basis of machine parameters currently communicated by the machine control level 11. “Soi production data that changes during ongoing production should be taken into account.

In order to meet the above requirements, the print shop, in conjunction with the warehouse 21, has the above-mentioned material flow system 05 for planning, coordinating and controlling the material flow in the print shop. In an advantageous embodiment, the material flow system 05 controls and manages the entire material flow in the system and is superimposed on the subsystems (transport system (s) 19, transport system (s) 46 and possibly other transport and preparation systems) of the roll supply system 02. It includes e.g. B. In addition to the direct roll supply, the handling of the goods receipt 18 and the management of the warehouse 21. If the warehouse 21 is designed with its own warehouse management system as a subsystem, the material flow system 05 has at least one interface to this subsystem.

The material flow system 05 receives information about planned and ongoing productions, for example via a signal connection from the higher-level product planning system 03 and / or from the printing press 01, in particular its control level 11. This data is processed in the material flow system 05, and the 1 /

individual orders to the subsystems mentioned. The movement control or the processing of the order itself is preferably carried out in the control assigned to the subsystem (partially autonomous).

Due to its topology and the transport routes, the described warehouse 21 is not primarily designed to hold a large number of different types of articles ready for quick access, as is the case with a picking warehouse, or to store large quantities of the same article for successive access ( Storage). Rather, it is designed to record the planned material requirements for an upcoming production period and to supply them to machine 01 in a production-oriented manner (buffer store).

The stored goods (rolls) can be stored in the delivery state (unprepared) and are prepared for production in the warehouse 21 by means of appropriate devices and processes (preparation circuit 35). This production preparation essentially refers to unpacking and preparing for automatic gluing (see above).

The warehouse 21 is advantageously provided with an automatic goods receipt 18 or an automatic storage route (transport routes 31, 33, 36) by means of which truck loads can be operated automatically or onto which rolls can be placed manually at random. In this area, the contour of the stored goods is checked, possibly defective rolls are ejected, and if necessary the rolls are automatically separated by a device, identified by barcode readers 53 and sent to the storage location of the relevant storage block 22; 23 transported.

The locations are designed such that paper rolls with a defined minimum diameter without loading aids are used with the respective operating devices 29; 30 or the transport system 19 transported and in the storage bins 26 to 28; 32; 34; 39; 48 can be stored. This eliminates handling, provision and the Management of loading aids (such as pallets).

For paper rolls that fall below the defined minimum diameter, the storage 21 loading aids, eg. B. in a specially provided area of Lageφlätze in the outer, the processing machine facing shelf block 23.

The warehouse 21 is ideally designed and equipped in such a way that material rolls stored in the delivery state can be automatically delivered to the unpacking and preparation circuit 35. The unpacking and preparation circuit 35 is part of the warehouse 35 and is equipped with fully automatic, semi-automatic or manually operated devices for unpacking (unpacking station 37) and adhesive preparation (adhesive preparation 38). The operation of the bearing 21 is optimized so that manual intervention is largely minimized.

The advantages of designing the bearing 21 come in particular in conjunction with a corresponding method for storage with an appropriate storage strategy for use. This method is characterized in that the storage in the warehouse 21 is already controlled and is optimized for the needs of the upcoming production period. This is achieved through an interface to the production planning system 03, via which the data of the upcoming productions are transmitted. This information is prepared in the material supply system and, on the basis of this data, roles for the storage - in particular unprepared roles - are requested. This requirement can be carried out via a list of requirements in paper form, via a display or via communication with an upstream storage area (storage) with its own warehouse management or a fast truck delivery.

To find the optimal time for production preparation, take this into account Process (or the logic implemented in the material supply system) at least the limited shelf life of the adhesive preparation, which must be coordinated with the planned production period. In addition, preferred preparation times can advantageously be taken into account in the logic: these can be time windows in which there are little or no productions (in order to achieve even utilization of the storage vehicles) and / or there can be time windows in the normal daily working hours for additions for shift - or to avoid night work. (Cost optimization).

The process is designed in such a way that the available space can be used in an optimized way to meet current requirements. This means that in the case of rapidly changing productions, a large number of different articles (rolls of different dimensions and / or quality) must be kept ready and relocated to the machine-related storage area (e.g. shelf block 23) in accordance with the production planning in order to achieve a high material throughput. For long productions, especially at night or at the weekend, a large number of the same items must be kept in stock and the production preparation must be optimally coordinated with the processing in order to be able to supply the system evenly over a long production period.

The method can also advantageously be designed to deal even in the event of an accident (e.g. if the preparation circuit 35 fails, if there is an unscheduled need for a roll type that is currently not in stock (sluice through) or if a similar item is supplied if the required item is not available is) to ensure the material supply of the production plant as far as possible. If the overlay fails

Material supply system 02, the method provides, for example, the possibility of configurator operation.

The process lies in parallel or approximately parallel processes for the Storage, relocation and operating the machine 01. Fig. 4 shows this in a rough flow chart.

In the left branch (putaway process), the logic or software underlying the material management system 02 reads the planned demand from the production planning system 03. This data is then evaluated with a view to an optimal storage strategy. This evaluation is the special design of the bearing 21 from the two outer and the inner bearing block in conjunction. the operating devices 29; 30, the preparation circuit 35 and the transport system 19, by means of which both unprepared and prepared rolls can be stored and relocated in the bearing 21. Although in principle there is a gradient from unprepared rolls to prepared rolls in the shelf blocks from goods receipt 18 to machine 01, the path of an unprepared roll is “backwards” from inner shelf block 24 to the machine (in contrast to conventional systems) 01 removed outer shelf block 22 or to the preparation circuit 35. The determination of the storage strategy is set out somewhat more specifically in FIG.

In the sub-process for determining the storage strategy ("definition of the optimal storage strategy" from FIG. 4), the paper or material roll requirement is first determined and a comparison is made with the inventory. Depending on the result, the need for the storage of new rolls is determined if there is a deficit ( of trucks, railway wagons or from a storage warehouse) in the warehouse 21.

At the same time, the expected inventory allocation is determined as a further criterion influencing the warehouse strategy. If this is low, the shelf block 22 remote from the machine is used only for unprepared rolls, the shelf block 23 near the machine is used only for prepared rolls and the inner shelf block 24 is kept largely free except for the passing of the rolls. If the storage occupancy is normal, the shelf block 22 remote from the machine is again used only for unprepared roles machine-related shelf block 23 only for prepared rolls and the inner shelf block 24, however, used as a buffer for unprepared and prepared rolls. The same procedure is used for high warehouse occupancy. For the criteria "high", "normal" and "low", what has been said below can be applied.

A further criterion is the type of requirement, whereby a distinction is made between many small successive productions and a few large ones. In the first case, sufficient space must be kept free for returns of rolls that have already started from the roll changers 06 to the warehouse 06. In the second case, the priority is the storage-optimized storage of unprepared and prepared roles.

Another advantageous influencing criterion for the formation of the warehouse strategy is the schedule for the storage of new roles in the warehouse 21. Here, a distinction is made between the intended storage period during and outside of normal working hours. In the first case, the storage of new rolls is preferably carried out (if there is sufficient capacity and the planned period of time until the planned consumption is not too great) via the preparation circuit 35 for preparation before they are fed to a shelf block 22 or 24. In the second case, the rolls are stored unprepared (e.g. packed and without glue preparation) and only prepared later (during normal working hours).

The results of the sub-strategies or criteria are now evaluated and the storage strategy is defined. For variants, only a subset of the sub-strategy mentioned can be included. If, in the case of a larger warehouse 21, there are several inner shelf blocks 24, the strategies are to be extended accordingly to “innermost” and “most distant” shelf blocks.

After the storage strategy has been defined, the storage request is issued, which the production preparation takes into account, taking into account production planning and, if applicable preferred preparation times.

In a parallel process (outsourcing process), material and return delivery requests are registered by machine 01 (e.g. reel changer 06) and checked to see if they can be served. If so, the request is served. In an advantageous embodiment of the method, in the event of a defect, this provides for checking the inventory for similar roll types (article) and, if the result is positive, for operating the machine 01 with it. Otherwise there is, for example, an immediate storage of a roll of the appropriate type, which in this case is to be passed through in the fastest way from the goods receipt 18 via the preparation circuit 35, the inner shelf block 24 and the machine-related shelf block 23. The definition for the decision to be made in FIG. 4 about a “similar article” (role) is stored in a table in an advantageous embodiment.

In the third parallel process (stock transfer process), the inventory is constantly checked for the planned need in such a way that the prepared and unprepared roles of the different role types are positioned in a way that is optimized for production. I.e. the rolls required at short notice should normally already be prepared and at least be located in the inner or the machine-near outer shelf block 23. Short-term here means, for example, a minimum lead time, which is at least a quarter of an hour (better half an hour) before the expected time when the material roll is required at template position 48. You should be in the direct access area of the machine-level operating devices 30. The rolls directly required for the roll changer 06 should already have been delivered to a template location 48 corresponding to the relevant roll changer 06. The time window for this should be at least 0 to 5 minutes before the roll changer 06 is called. In the storage area remote from the machine - for example in the access area of the operating devices 29 remote from the machine, preparation and storage takes place for the roles required in the medium term. This can include unprepared roles, for example from the outer or inner shelf block 22 remote from the machine; 24 are removed and fed to the preparation circuit 35 before these are then temporarily stored as prepared rolls in the inner shelf block 24. This is then accessible to the machine-related operating device 30 and can be called up at short notice. In accordance with the planned need, a production-oriented relocation of unprepared and prepared roles takes place in warehouse 21 in the third sub-process. The determination of the relocation strategy is set out in more detail in FIG. 6.

In the "relocation" sub-process, the allocation strategy ("meaningful relocation in a production-oriented manner" from FIG. 4) is determined by first determining the warehouse utilization and distinguishing between low, normal and high warehouse occupancy. Depending on this, the roles are stored away optimized with minimal occupancy under the premise of minimal rearrangements, i. H. Rearrangements should be avoided if possible. With normal occupancy, the roles are stored in a way and space-optimized, whereby a needs-based relocation is permitted. If there is a high occupancy, the rolls are to be stored in a space-optimized manner, with relocation taking place according to the production. The optimization with regard to path and / or space and / or the number of rearrangement processes can be carried out by means of mathematical algorithms which search for the conditions of a local or absolute minimum for the relevant (n) - possibly weighted variable (s) taking into account boundary conditions. This can be done with consideration only of the next step (e.g. movement of a single roll), but advantageously with consideration of a number of upcoming storage and / or retrieval operations, so that an optimized strategy is developed overall. Ideally, the entire upcoming production period is included in the determination of the strategy, so that, if necessary, individually considered relocation steps within a short period of time (e.g. at the beginning) would not be an optimal solution, but the overall process as a whole optimal process.

“Path-optimized” means, for example, that one for a reel changer 06 suitable, prepared roll is stored as close as possible to the template space 48 assigned to it - for example directly to the left or right thereof. This pure form of the strategy is possible in a simple manner with low utilization or occupancy of the warehouse 21, for example at least below 50%, in particular below 40%.

With increasing occupancy or occupancy (normal), for example over 50%, a purely "path-oriented" strategy becomes increasingly difficult due to the high occupancy. There are still more vacancies "space-optimized", i. H. chaotic about the bearing 21 in such a way that a reel changer 06 with a suitable reel can always be operated via a middle path. The chaotically stored rollers are, for example, distributed substantially uniformly over the length of the bearing 21 which corresponds to the roller changer 06 in operation.

If the load or occupancy is high, e.g. B. at least greater than 60%, in particular greater than 70%, the strategy of storage (unprepared and prepared roles) is “space-oriented, d. H. the rollers in the bearing 21 are stored chaotically over the length of the roller changers 06 which are in operation and are to be supplied. In extreme cases, for. B. in the machine-near bearing block 23 all Lageφlätze used.

The sub-processes described (storage, retrieval and relocation process) are preferably iteratively run continuously. In principle, it is also possible for the processes not to run continuously next to each other, but one after the other.

The layer 21 described can be used in particular as a buffer store 21 without the need for an upstream storage store, since both unprepared and prepared material rolls are stored and managed in this store 21. A delivery, ie Unprepared rolls of material can then be stored, for example, directly from goods receipt 18 (from trucks, rail wagons, etc.). If, in one variant, a storage warehouse is arranged exclusively for unprepared rolls of material, a material output from this storage warehouse is to be understood as "goods receipt" 18 in the aforementioned sense. The barcode reader 53 can then be omitted at the point shown, since such information about the size and quality of the storage facility 21 role to be stored can be taken from the information available in the storage facility.

The criteria "high", "normal" and "low" and / or "many small", "few large" (FIGS. 5 and 6) can each be stored as concrete limit values (changeable) functionally or in tabular form. However, they can Depending on the overall system, machine size and / or warehouse size, the definition of these criteria can be different and should therefore be changeable. In an advantageous further development, the system can also be designed to be fully or partially self-learning, so that the boundaries between the different modes or criteria in certain areas are shifted by practical experience.

An overall procedure for storing unprepared and prepared material rolls of the web-fed rotary printing press can now advantageously be carried out in such a way that production-relevant data about planned productions (amount of paper and / or type and / or point in time) is sent directly from the production planning system 03 or via the machine 01 to be supplied via a signal connection the computing and / or data processing unit 17 are transmitted, in a first sub-process by the computing and / or data processing unit 17 on the basis of the transmitted consumption data for the upcoming production period and the current inventory, the definition of a storage strategy and, as required, a storage request for new, unprepared material rolls takes place, and the logic implemented in the material supply system 05 provides a point in time for the production preparation of unprepared material rolls, taking into account a limited durability of the adhesive preparation and the planned production period is determined. In a second sub-process, material roll requests from the machine 01 are directed to the material flow system 05 via a signal connection, are registered in its computing and / or data processing unit 17, and are checked there for availability by the warehouse 21 on the basis of available data for warehouse occupancy and if the result is positive In accordance with the request from machine 01, an order is placed directly by the material flow system 05 or via a warehouse management system for outsourcing to an operating device 29; 30 of the bearing 21 is made. In a third sub-process, the material flow system 05 uses the transmitted production-relevant data to check the warehouse occupancy for the planned demand in such a way that the prepared and unprepared material rolls of the required roll types are positioned in a production-optimized manner, whereby a strategy for a Production-oriented relocation of unprepared and prepared roles within the warehouse 21 is determined and carried out.
