• sufficient space must be kept free for returns of rolls that have already started from the roll changers 06 to the warehouse 06.
• the priority is the storage-optimized storage of unprepared and prepared roles.
• the schedule for the storage of new roles in the warehouse 21 is the schedule for the storage of new roles in the warehouse 21.
• the intended storage period during and outside of normal working hours 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.
• the rolls are stored unprepared (e.g. packed and without glue preparation) and only prepared later (during normal working hours).
• the storage request is issued, which the production preparation takes into account, taking into account production planning and, if applicable preferred preparation times.
• 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.
• machine 01 e.g. reel changer 06
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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%.
• the strategy of storage 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 Lü ⁇ lharte used.
• the sub-processes described 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” 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.
• 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
• 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.
• 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.
