Abstract

The invention relates to a method for storing rolls of prepared and unprepared material of a web-processing machine in a warehouse. According to said method, information that is used to anticipate consumption data for an impending production period or anticipated consumption data is supplied to a material flow system (05) comprising implemented logic and a warehousing strategy is defined in a sub-process using the anticipated consumption data and the current inventory.

Description

The invention relates to methods for the storage of rolls of material according to claim 1 or 2.

By the DE 39 10 444 C2 a device for supplying material to a system, in particular a printing press is known, wherein rollers are stored in a buffer storage. The bearing has two rack blocks, between which a stacking device is provided, which is designed to operate both rack blocks. With this storage system, it is possible, for example, to prepare rolls during the day, to temporarily store them and to feed the roll changers at night, or to prepare interposed rolls at night and feed them directly to the roll changers.

The DE 100 57 735 A1 discloses a system for picking articles with a plurality of parallel rows of shelves, wherein between the rows of shelves alternately storage and picking lanes are.

By the DE 21 58 537 A a storage system is disclosed wherein memory locations of a central row of shelves can be operated from corridors adjoining on both sides.

In the DE 37 38 052 A1 a storage and provision system of processing material of a production line is known, wherein the shelves are divided into supply and storage areas and a storage of the goods and a removal or relocation from stock to the staging area or other rack aisles is process-computer controlled.

The US 5 076 751 A discloses a warehouse in which an implemented logic having computers before a production run this forecast consumption data supplied and a storage strategy is set in the form of a plan for the required material rolls, the processed rolls outsourced in a particular order from a warehouse and stored in rack blocks become.

EP 0 334 366 A2 discloses three storage areas, namely a designed as a fireplace warehouse main warehouse, an intermediate storage and a roll template. In the interim storage bins are provided next to each other multi-row, which can be reached by a crane device from above.

In the DE 44 16 213 A1 a main bearing and an intermediate storage is disclosed, wherein the intermediate storage is designed as a shelf storage. The intermediate storage facilities are designed as single-sided shelf blocks. Only unpacked and adhesive-prepared rolls can be stored here in a common storage area.

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

The object is achieved by the features of claim 1 or 2.

The advantages achieved by the invention are, in particular, that with the bearing a high flexibility and a supply is ensured even in load peaks. The storage space to be kept is optimized.

A concept of several, at least partially overlapping in the longitudinal direction shelf blocks allows both independent of the production process delivery of unprepared roles as well as a fast passing through of prepared roles in the printing press closer shelf block.

The formation of an inner shelf block as accessible from both longitudinal sides, allows a very efficient displacement of the rollers between the blocks. The loading and unloading of a roll from an inner shelf block is not tied to a control unit of a corridor, so that from one side a loading of the shelf block can be done while at the same time a removal can be done from the other side. A bypassing of a storage block, and thus a mutual obstruction of various operating devices, can be avoided.

Embodiments of the invention are illustrated in the drawings and will be described in more detail below.

In addition or as an alternative to the signal connection 16, a transfer can take place via an optional signal connection 20 from the product planning system 03. If present, 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, to these two - in the context of its tasks - be superior.

A possible hardware configuration of a roll supply system 02 is schematically illustrated in FIG Fig. 2 However, in a device according to the invention and / or for the procedure according to the invention, not all of the subsystems described below must be present, and the individual functional subsystems can be embodied in ways other than those set forth.

In the embodiment according to Fig. 2 has the roll supply system 02 as subsystems z. B. at least one goods receipt 18, a first transport system 19, and at least one bearing 21.

The bearing 21 has in the longitudinal direction next to each other at least three, at least in the longitudinal direction partially overlapping shelf blocks 22; 23; 24, with one of the roll changers 06 remote outer shelf block 22, a reel changers 06 next shelf block 23 and a lying between the two shelves blocks 22 and 23 inner shelf block 24. As a shelf block 22; 23; 24 here is an arrangement of adjacent, in particular in an alignment located storage bins 26; 27; 28 (in Fig. 2 only one storage bin 26; 27; 28 per shelf block 22; 23; 24) to understand which side by side and / or one above the other can each take a role.

The middle shelf block 24 is now designed such that at least in one area an associated storage space 28 from both longitudinal sides of the shelf block 24 is operable. For this purpose, the shelf block 24 in an advantageous embodiment in this area only a storage space 24 in its width.

If several storage bins are to be provided in width, then care must be taken that only one of the storage bins arranged one behind the other is occupied in the area provided for the purpose here, and that an operating device has the corresponding reach in order to pass over an empty storage bins to move a role.

Between each two shelf blocks 22; 23; 24 are longitudinally extending free spaces, z. B. corridors, provided, which in each case at least one transport system 29; 30, z. B. a stacker crane 29; 30, is assigned. The between two shelves 22; 23; 24 arranged stacker cranes 29; 30 are preferably adapted to be stored in storage spaces 26; 27; 28 of both adjacent shelf blocks 22; 23; 24 can access. The stacker cranes 29; 30 are preferably designed such that cooperating with the rollers tool having 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 path 31 from the delivery to the warehouse 21. In particular, at least one transport path 31 is provided to a storage space 32 of the outer shelf block 22 through which z. B. serves as a transfer station 32 during storage or is designed such.

In a preferred embodiment, the transport system 19 additionally comprises at least one transport path 33 to a storage location 34, z. B. as a transfer station 34, the inner shelf block 24. For this purpose, the outer shelf block 24 has an access, for example a passage or the outer shelf block 24 does not extend over the same length of the inner shelf block 24 as in the embodiment according to Fig. 2 the case is. From the incoming goods, z. B. not yet prepared rolls 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 circle 35, which from the goods receipt 18 z. B. via an unpacking station 37 and / or an adhesive preparation 38 to a storage space 39, z. B. as a transfer station 39, the inner shelf block 24 leads. Again, for example, an o.g. Implementation or shortening of the outer shelf block 22 is provided.

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

In an advantageous development, the transport system 19 at least one of the transport path 32 different transport path 41, on which roles from a storage location 42, z. 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 adopted. A stored, unprepared roll can thus be removed, for example, again and prepared via the transport path 36 and fed to the inner shelf block 24.

Likewise, in an advantageous embodiment, the transport system 19 at least one of the transport path 33 or 36 different transport path 43, on which roles from a storage space 44, z. 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 adopted. A stored in the inner shelf block 24, unprepared role can be removed, for example, again and prepared via the transport path 36 and in turn fed to the inner shelf block 24.

The arranged between the outer shelf block 22 and the inner shelf block 24 control unit 29 now takes, for example, the delivered at the storage location 32 role and stores it z. B. on a free storage space 26 of the outer shelf block 22 to. As a rule, the outer shelf block 22 only unprepared roles. In exceptional situations, however, it can also serve as a buffer for already prepared roles. This can be z. For example, if a long break in production has been used for preparation and / or a large production is planned.

If certain logistical reasons or if the outer shelf block 22 is already fully populated with unprepared roles, then the operating unit 29 takes over the delivered, z. B. unprepared role and stores them on a storage space 28 of the inner shelf block 24 a. The inner shelf block 24 serves as a buffer for unprepared roles. For the purpose of preparation, these can then be returned to the transport system 19, and thus to the unpacking station 38 and / or the adhesive preparation 38, again by the operating unit 29 from the storage space 28 via the storage space 42 of the outer shelf block 22.

The between the inner shelf block 24 and the next to the roll changer 06 outer shelf block 23 arranged control unit 30 is also adapted to both adjacent shelf blocks 23; 24 to use. It now takes over, for example, a delivered at the storage location 39, already prepared role and stores them z. B. on a free storage space 28 of the inner shelf block 24 to. The inner shelf block 24 may contain prepared as well as unprepared rolls according to the above-mentioned embodiments. However, he can only have prepared roles when z. B. planned a large production is. In exceptional situations, only unprepared roles can be stored, for example, if a longer break in production is imminent and / or a correspondingly large delivery has taken place.

By the control unit 30 can now unprepared roles from the storage space 34 z. B. on a free storage space 28 of the inner shelf block 24 or on a free storage space 27 of the reel changers 06 next shelf block 23 rearrange.

If certain logistical reasons, so exceptionally by the control unit 30 and unprepared roles from the inner shelf block 24, z. B. from the storage space 34 or a storage space 28 in the reel changer 06 next shelf block 22 are stored for buffering.

Basically, however, the inner shelf block 24 is used for buffering prepared and unprepared rolls, so that preferably only unprepared rolls are located in the outer rack block 22 remote from the roll changer 06, and only prepared rolls are stored in the rack block 23 closest to the roll changer 06. The outer bearing block 22 is thus used together with parts of the inner bearing block 24 in the function of a main bearing, and the reel changer 06 next shelf block 23 together with parts of the inner shelf block 24 as so-called. Day camp.

Between the outer shelf block 28 and the roll changers 06, a further transport system 46 is provided, by means of which rolls can be removed from the shelf block 23 and fed to the or one of the roll changers 06. The transport system 46 can basically in any way, for. B. with forklifts, with "driverless transport systems" (FTS), rail-bound or tired vehicles, manned or unmanned, executed. It is advantageous, however, if it is designed driverless and by a higher-level control and / or control system, eg. B. by the material flow system 05, or by an associated reel changer 06 its Orders received.

In the example, each reel changer 06 is designed as a rail-mounted transport system 47 inner feed circuits 47, z. B. driven rail-mounted trolley with appropriate guides assigned. These transport systems 47 are in the rack block 23 for transfer or template serving bins 48, z. B. template 48, assigned.

In the aforementioned embodiment, with each reel changer 06 defined template space 48, the necessary or required for the respective reel changers 06 roles submitted by the control unit 30. These can be taken from the storage bins 27 of the rack block 23 or the storage bins 28 of the inner shelf block 24. In special cases, a role can be directly removed from the transfer station 39 and delivered to the template place 48 by the operating device 30.

In an unillustrated embodiment, the removal of the required roll can also take place by means of a transport system 46, the transport then taking place, for example, by means of transport (for example a manned forklift or an AGV) not assigned to a single reel changer 06. In this case, if necessary, no fixed template positions 48 for the individual roll changers 06 must be defined. In such an embodiment, for example, a means of transport can then be used to order from one of the various storage locations 48 provided for presentation. If all or some of the storage bins 27 are accessible from both sides in one development, then the rollers corresponding to the requirements can be taken directly from the transport means to the rack block 23.

The operating devices 29; 30 are preferably as in Fig. 3 shown as storage and retrieval units 29; 30 executed. A gripping and / or lifting mechanism 51 is disposed on a vertical mast 52 in the manner and driven to move in the vertical direction from a storage location of a lowermost level E1 of the respective shelf block 22; 23; 24 is movable to a storage location of a top level E11. The carrier 52 is supported and driven in the lower portion and the upper portion of the bearing 21 in such a manner as to be horizontally movable 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 rack blocks 22; 23; 24 record or roles can settle there. In Fig. 3 can be further seen that the inner shelf block 24 in its width only a single storage space 28; 34; 39, 44 which, from both sides of the shelf block 24 by the respective operating device 29; 30 is accessible.

When selecting a role or storage space 27 or 28 by the operating device 30 and the subsequent template 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 the direct access to the storage bins 27 by an alternative transport system 46th

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

In a particularly advantageous embodiment, the bearing is 21 (with warehouse management system), the goods receipt 18 and at least the outer, ie the located outside of the warehouse 21 transport systems 19; 46 integrated into a material flow system 05, which is in communication with the control level 11 and / or the product planning system 03. Will the operator panels 29; 30 not commissioned by a warehouse management system, the function of warehouse management and contracting to the operator panels 29; If necessary, also be carried out by the material flow system 05.

The integration into a material flow system 05 is 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 described material supply system 02, the formation of the bearing 21, z. B. in conjunction with all or some of the above transport routes 31; 33; 36; 42; 43, is of particular advantage in connection with printing machines 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, as shown in FIG Fig. 2 is shown.

The bearing 21 extends over the entire length of the two printing presses 01. Here, the reel rack 23 closest to the roll changer 06 extends substantially over the entire length from the first to the last reel changer 06. The inner shelf block 24 extends in the example over the same length. To allow direct access from the goods receipt 18 to the inner shelf block 24, the outer, the goods receipt 18 nearest shelf block 22 is made shorter. This is substantially symmetrical to the two to be supplied printing machines 01. In the example, the material supply system 02 on two areas for the goods receipt 18, which are connected via a respective transport system 19 with storage spaces 32 in the near-end areas of the shelf block 24. In the corridors between each two shelves 22; 23; 24 are a plurality of operating devices 29; 30 provided.

The illustrated embodiment of the bearing 21, in particular i. V. m. the printing press system, allows a particularly flexible supply of printing presses 01, since not only with the inner shelf block 24 a buffer function is achieved, but also a supply of a printing press 01 can be done with rollers from one 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 may be provided, which then each only have a storage space in their width. Between each two shelf blocks 22; 23; 24 is then ever a control unit 29; 30 arranged.

1. a) liegender Transport der Papierrollen und rollen der Rollen über den Umfang;
2. b) stehender Transport der Papierrollen auf einem LKW / Bahnwaggon / Schiff mit Bodenschienen;
3. c) stehender Transport der Papierrollen auf speziellen LKW / Bahnwaggon / Schiff, die eine Art Förderband auf der Ladefläche aufweisen.

In the simplest case, the goods receipt 18 consists of a transfer position to the automatic reel supply and an input option for the reel input information. Optionally, however, it is advantageous not to unload the truck, train or ship with the forklift but to automate. Here are three fundamentally different models can be distinguished:

1. a) lying transport of paper rolls and roll the rollers over the circumference;
2. b) stationary transport of the paper rolls on a truck / railway wagon / ship with floor rails;
3. c) stationary transport of the paper rolls on special truck / train wagon / ship, which have a kind of conveyor belt on the loading area.

The goods receipt 18 may be assigned a role separation. In particular, half and quarter width rolls are i.d.R. standing transported one above the other. In this case it is necessary to singulate the rolls, i. lift the upper roll and place it next to the lower one, etc.

In an automatic system, an accident can occur if the accident Transporting goods do not conform to the expected shape. Therefore, it is expedient to check compliance with the outer shape within certain tolerances and to additionally assign a contour control to the goods receipt 18. For paper rolls, systems using photocells, light curtains or area scanners, to which a more or less intelligent evaluation is connected, are suitable.

Furthermore, it is advantageous if in the area of the goods receipt 18, the delivered role, for example via a bar code, z. B. bar code reader 53, or another system is identified. The barcode label identifies the roll and is detected by the system.

The bearing 21 is z. B. for horizontal storage of prepared or unprepared roles in multiple levels E1 to E11 designed as a high-bay warehouse 21. The high-bay warehouse 21 can in principle also be able to receive pallets or upright rollers. Are the rollers in the main bearing 21 but z. B. stored, so at least either the operator panels 29; 30 or the transport system 46 allow tilting of the role, or it is between bearing 21 and reel changer a tilting station arranged.

As a rule, a preparation circle 35 has the unpacking station 37 and the adhesive preparation 38 executed, for example, as an adhesive preparation machine. In addition, if necessary transfer positions in the transport system 19. The unpacking station 37 has z. B. a means on which the paper rolls can be aligned and partially automatically unpacked. In addition, here the barcode, z. B. detected by means of a handheld scanner for checking, the diameter determined and the role to be weighed to control. The adhesive preparation 38 represents, for example, an automatic adhesive preparation system. A suitable adhesive preparation 38 may e.g. B. prepare about 15 rolls per hour.

When refilling the bearing 21, in particular the shelf block 23 and parts of the shelf block 24 with prepared roles, it should be noted that the adhesive preparation u.U. only limited time, currently z. B. 8-12 hours, is durable and then needs to be renewed. In the camp 21, if necessary, residual rolls on loading aids, which were returned by a roll changer 06, and loading aids must also be handled.

A roll changer 06 has z. B. two Tragarmpaare, for receiving paper rolls. Each reel changer 06 is assigned a piece of conveyor track on which a paper roll for the reel changer 06 can be presented. The roll changer 06 with its buffer position (Vorlegeplatz) is then z. B. also referred to as inner feed circle 47 and is part of the printing machine 01 or assigned to this. It is used to unwind the paper rolls and to automatically change the rolls with gluing.

For transport over longer horizontal distances, such. B. between goods receipt 18 and warehouse 21, z. B. plate or belt or plate conveyor used, which work similar to a conveyor belt. For route transports between goods receipt 18 and warehouse 21 or between warehouse 21 and printing machine 01 z. B. also designed as driverless trucks transport systems 19; 46 are used. However, it is advantageous within the preparation circles 35 and 31 in the inner feed circuits rail-bound transport systems 19; 46, z. B. driven rail-mounted trolley with appropriate guides used. In small to medium-sized systems, the entire roller transport can also be realized by means of rail-mounted transport trolleys.

The motion control of the transport systems 19; 46 is done in an advantageous development in each case by a transport system 19; 46 associated control, z. As a programmable logic controller, in particular a configurator PLC (including control panel, with which driving jobs are configurable), or in advantageous embodiment by a transport system 19; 46 assigned arithmetic unit, z. B. a vehicle control computer.

The roll supply system 02 should be capable of producing a printing machine 01 or printing press system with one or more machine lines, each consisting of several sections A; B can provide sufficient and timely with prepared paper rolls. Further, it is desirable that the reel supply system 02 be able to process reel requests and reeliver orders from roll changers 06. Ideally, it is able, based on the product planning system 03 notified production data the current paper needs, eg. B. also on the basis of currently notified by the machine control level 11 current machine parameters. During production, changing "target" production data should be considered.

To meet the above requirements, the printer in conjunction with the bearing 21 on the above material flow system 05 for planning, coordination and control of material flow in the printing on. The material flow system 05 controls and manages the entire material flow in the system in an advantageous embodiment 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 contains z. B. the direct role supply the handling of the goods receipt 18 and the management of the warehouse 21. If the warehouse 21 running with its own warehouse management system as a subsystem, the material flow system 05 has at least one interface to this subsystem.

Information about planned and ongoing productions gets the material flow system 05, for example via a signal connection from the parent product planning system 03 and / or from the printing press 01, in particular the control level 11. These data are processed in the material flow system 05, and the individual orders supplied to the subsystems mentioned. The movement control or the execution of the order itself, preferably takes place in the subsystem associated control (semi-autonomous).

Because of its topology and transport routes, the described bearing 21 is not primarily designed to provide a variety of different articles for quick access, as is the case with a picking warehouse, or to store large quantities of the same article for successive access ( Storage). On the contrary, it is designed to accommodate the planned material requirement for an upcoming production period and to serve it in a production-appropriate manner to the machine 01 (buffer storage).

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

The bearing 21 is advantageously provided with an automatic goods receipt 18 or an automatic storage path (transport paths 31, 33, 36), by which truck loads can be automatically operated or on which manually reels can be placed indiscriminately. In this area, the contour of the stored material is checked, possibly faulty roles discharged, also the roles are automatically separated if necessary by a device identified by bar code reader 53 and to the storage of the respective storage block 22; 23 transported.

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

For paper rolls, which may fall below the defined minimum diameter, the bearing 21 loading aid, z. B. in a specially designated area of storage spaces in the outer, the processing machine facing shelf block 23 have.

The bearing 21 is ideally designed and equipped so that stored in the delivery state material rolls can be automatically tendered in the unpacking and preparation circle 35. The unpacking and preparation circuit 35 is part of the warehouse 35 and 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 the embodiment of the bearing 21 come in particular i.V.m. a corresponding method for storage with a corresponding storage strategy for use. This method is characterized in that the storage is already controlled in the warehouse 21 and optimized to the needs of the upcoming production period happens. This is achieved by an interface to the production planning system 03, via which the data of the upcoming productions are transmitted. This information is processed in the material supply system and, on the basis of this data, it is requested to store repositories, in particular unprepared roles. This requirement can be executed via a list of requirements in paper form, via a display display or via communication with an upstream storage area (storage) with own warehouse management or a fast truck delivery.

This is taken into account in order to find the optimum time for production preparation Method (or the implemented in the material supply system logic) at least the limited shelf life of the adhesive preparation, which must be coordinated with the planned production period. In addition, advantageously, preferred preparation times may be considered in the logic: these may be timeslots in which there are no or few productions (to achieve even utilization of the stock vehicles) and / or timeslots in the normal daily working time to add supplements by shift - or to avoid night work. (Cost optimization).

The method is designed so that the available storage space can be optimally utilized to the 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-oriented storage area (eg shelf block 23) in order to achieve a high material throughput. For long productions, especially at night or on weekends, a large number of identical articles must be held and the production preparation must be optimally adapted to the processing in order to be able to supply the plant evenly in a long production period.

The method may advantageously also be designed to be in case of emergency (eg in case of failure of the preparation circle 35, unscheduled need for a type of reel, which is currently not in stock (through) or delivery of a similar item, if the required not available is) to ensure the material supply of the production plant as far as possible. In case of failure of the superimposed material supply system 02, the method provides, for example, the possibility of a configurator operation.

The process is parallel or approximately parallel processes for the Storage, the rearrangement and the operation of the machine 01 based. Fig. 4 shows this in a rough flow chart.

In the left branch (storage process), the planned requirement from the production planning system 03 is read in by the logic or software underlying the material management system 02. These data are subsequently evaluated with regard to an optimal storage strategy. This evaluation is the special training of the bearing 21 from the two outer and the inner bearing block iVm the control units 29; 30, the preparation circle 35 and the transport system 19, by means of which in the camp 21 both unprepared and prepared roles can be transferred and relocated. Although, in principle, from the goods entrance 18 to the machine 01 in the rack blocks, there is a gap from unprepared rolls to prepared rolls, (unlike conventional systems) the path of an unprepared roll is also "backwards" from the inner shelf block 24 to the machine 01 remote outer shelf block 22 or the preparation circle 35 out feasible. The definition of the storage strategy is a bit more specific Fig. 5 explained.

In the sub-process for determining the storage strategy ("Defining the optimal storage strategy") Fig. 4 ), the paper or material roll requirement is first determined and made a comparison with the stock. Depending on the result of a deficit, the requirement for the storage of new roles (trucks, train wagons or a storage warehouse) is determined in the camp 21.

At the same time, as a further criterion influencing the storage strategy, the expected stock utilization is determined. If this is low, then the machine-remote shelf block 22 is only used for unprepared roles, the machine-near shelf block 23 only for prepared roles and the inner shelf block 24 is kept largely free to pass through the roles. If the stock allocation is normal, the machine-remote shelf block 22 is again only for unprepared roles, the Machine-near shelf block 23 only used for prepared roles and the inner shelf block 24 but used as a buffer for unprepared and prepared roles. The same procedure is used for high storage occupancy. For the criteria "high", "normal" and "low" the below can be applied.

As a further criterion, the type of demand flows in, distinguishing between many small successive productions and a few large ones. In the first case, sufficient places for return deliveries of already started rolls from the roll changers 06 to the stock 06 are to be kept free. In the second case, priority is given to the route-optimized storage of unprepared and prepared roles.

Another advantageous influencing criterion for forming the storage strategy is the schedule for the storage of new rolls in the warehouse 21. Here, a distinction is made between the intended storage period during and outside a normal working time. In the first case, it is preferable to store new rolls (if capacity is sufficient and scheduled time to planned consumption is not too great) via preparation circle 35 for preparation before being fed to a shelf block 22 or 24. In the second case, the rolls are stored unprepared (eg packed and without adhesive preparation) and prepared later (during normal working hours).

The results of the sub-strategies or criteria are now evaluated and the storage strategy determined. For variants, only a subset of the sub-strategy mentioned can be included. If, in the case of a larger bearing 21, there are a plurality of inner shelf blocks 24, the strategies for "machine-closer" "innermost" and "machine-distant" shelf blocks must be expanded accordingly.

Once the storage strategy has been determined, the storage requisition is issued, followed by the production preparation, taking into account the production planning and, if necessary, preferred preparation times connects.

In a parallel process (outsourcing process), material and return requests are registered by the machine 01 (eg, the roll changer 06) and checked for their serviceability. If so, the request is serviced. In an advantageous embodiment of the method, this provides in the case of a defect, to check the stock for similar types of reels (article) and to serve the machine 01 with this result with a positive result. Otherwise, for example, an immediate storage of a role appropriate type, which in this case from the goods receipt 18 on the preparation circle 35, the inner shelf block 24 and the machine-oriented shelf block 23 is passed through the fastest way. The definition for in Fig. 4 decision to be made about a "similar article" (role) is tabulated in an advantageous embodiment.

In the third parallel process (stock transfer process), the stock allocation is constantly checked for the planned demand in such a way that the prepared and unprepared roles of the different role types are positioned production-optimized. Ie. The short-term required roles should be prepared as a rule already and at least in the inner, or the machine-related outer shelf block 23 are. By short-term here is, for example, a minimum lead time to understand, which is at least a quarter of an hour (better half an hour), before the expected date of the requirement of the roll of material at the template place 48. They should be located in the direct access area of the machine-accessible operating devices 30. The roles required immediately for the roll changer 06 should already be delivered to a template space 48 corresponding to the relevant roll changer 06. The time window for this should be at least 0 to 5 minutes before retrieval by the reel changer 06. In the storage area remote from the machine - for example in the access area of the remote operating devices 29, there is a preparation and storage for the roles required in the medium term. Here, for example, unprepared roles from the off-machine outer or inner shelf block 22; 24 are removed and fed to the preparation circle 35 before they are then stored as prepared rolls in the inner shelf block 24. This is then the machine-oriented control unit 30 accessible and available at short notice. According to the planned demand, a production-oriented relocation of unprepared and prepared roles takes place in the third sub-process in the warehouse 21. The determination of the repositioning strategy is in Fig. 6 set out in more detail.

In the sub-process "Stock transfer" the allocation strategy ("meaningful redeployments production-oriented") is selected Fig. 4 ) is determined by first determining the warehouse utilization and differentiating it into low, normal and high warehouse occupancy. Depending on this, at low occupancy, the roles are stored away optimally under the premise of minimal rearrangements, ie rearrangements are to be avoided as far as possible. With normal occupancy, the roles are stored away space and space, with a demand-oriented repositioning is allowed. In case of high occupancy, the rolls are to be stored in a space-optimized manner, whereby a repositioning takes place according to production. The optimization with regard to path and / or space and / or the number of relocation processes can be carried out by means of mathematical algorithms which search for the relevant (optionally) weighted variable (s) taking into account boundary conditions states of a local or absolute minimum. This can take place in consideration of only the next step (eg movement of a single roll), but advantageously taking into account several pending inputs and / or removals, so that overall an optimized strategy is developed. Ideally, the entire upcoming production period will be included in the determination of the strategy, so that if individually considered stock transfer steps within a small time span (eg at the beginning) would not be an optimal solution, the overall process would become one optimal process is.

By "distance optimized" is meant, for example, that one for a reel changer 06 matching, prepared role as close as possible to this assigned template space 48 is stored - 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 bearing 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 is made increasingly difficult by the high occupancy. There are still more vacant places "space-optimized", d. H. chaotically occupied by the bearing 21 in such a way that is always a reel changer 06 with a suitable role over a middle way to use. The chaotically stored rollers are, for example, substantially uniformly distributed over that length of the bearing 21 which corresponds to the roller changer 06 in operation.

If the utilization or occupancy is high, z. B. at least greater than 60%, in particular greater than 70%, the strategy of storage (unprepared and prepared roles) "place-oriented, ie the rollers are stored in the bearing 21 chaotically over the length of the in-use and to be supplied reel changer 06 In extreme cases, for example, all storage bins are utilized in the machine-oriented storage block 23.

The described sub-processes (storage, paging and stock transfer process) are preferably run continuously iteratively. In this case, it is also possible in principle for the processes not to be run next to one another but repeatedly one after the other repeatedly.

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

The criteria "high", "normal" and "low" and / or "many small", "a few large" ( Fig. 5 and 6 ) can be stored on the one hand as concrete limit values (changeable) in functional or tabular form. However, they can also be based on fuzzy control as terms of linguistic variables. Depending on the overall system, machine size and / or bearing size, the definition of these criteria may be stored differently and should therefore be changeable. In an advantageous embodiment, the system can also be wholly or partially self-learning, so that boundaries between the different modes or criteria in certain areas are moved by the practical experience.

An overall procedure for the storage of unprepared and prepared material rolls of the web-fed rotary printing press can now advantageously be designed such that production-relevant data on planned productions (amount of paper and / or type and / or time) directly from the production planning system 03 or via the machine to be supplied 01 via a signal connection the computing and / or data processing unit 17 are transmitted, wherein in a first sub-process by the computing and / or data processing unit 17 based on the transmitted consumption data for the upcoming production period and the current inventory, the definition of a storage strategy and, as required, a Einlageraufforderung for new, unprepared material rolls takes place, as well as by the implemented in the material supply system 05 logic a point in time for the production preparation of unprepared material rolls taking into account a limited shelf life of the adhesive preparation and the planned production period. In a second sub-process, material roll requests of the machine 01 are directed to the material flow system 05, registered in its computing and / or data processing unit 17, and there checked for availability by the bearing 21 on the basis of existing data for stocking and with a positive result according to the request of the machine 01 an order directly through the material flow system 05 or via a warehouse management system for removal to an operating unit 29; 30 of the bearing 21 is made. In a third sub-process, the stock allocation is checked by the material flow system 05 on the basis of the transmitted production-relevant data on the planned demand in such a way that the prepared and unprepared material roles of the required role types are positioned production optimized, according to the planned needs, a strategy for a production-oriented relocation of unprepared and prepared roles within the warehouse 21 is determined and carried out.
