Definitions

  • the invention relates to a method for order control of a production process for a fiber product and to an apparatus for carrying out the method according to the preamble of claim 11.
  • the production of fiber products is largely determined by the quality specifications that the fiber product should have. Regardless of whether the fiber product is a single fiber or a sheet, certain use-specific properties are required. For example, from the EP 0 580 071 A2 describe the production of a synthetic fiber in which the quality of the fiber produced is continuously monitored during the process. In the case of deviations, a process change in the production process can be carried out selectively. The manufacturing process is usually monitored and controlled from a plant control unit out.
  • the fiber products to be produced are determined by individual production orders. Each manufacturing lot of a fiber product is thus directly based on a production order.
  • the difficulty arises that, due to the complex processing steps for producing the fiber product, a large number of influencing variables leads to disruptions in the production process being unavoidable due to fluctuating quality of the fiber product or process interruptions.
  • the fiber product is divided into quality grades A, B and C.
  • a production order with a target specification of a certain product quantity of quality A can only be produced as efficiently as possible if the quality levels B and C are insignificant or even non-existent during the production process.
  • this can not be realized, since a bobbin with the crimped yarn is already rated B quality if, for example, a thread knot is formed inside the thread bobbin, which results from the transition from a supply bobbin to a reserve bobbin. Therefore, a planning for the execution of several successive production orders is hardly possible or only with a great deal of effort.
  • Another object of the invention is to constantly monitor the manufacturing process with respect to the underlying production mission.
  • the object is achieved by a method having the features of claim 1 and by a device having the features of claim 11.
  • the invention is characterized in that an intelligent connection between the business processes and the manufacturing processes is created. This is already possible when creating new production orders within of the business process incorporate the current situation in the manufacturing process.
  • an actual nominal evaluation is carried out between the predetermined target specification for production of a fiber product and the respective actual state of the production process, which was triggered on the basis of the production order. In this case, a deviation from the target specification is displayed, so that both the current production order located in the manufacturing process and also the following production orders can be adjusted.
  • the actual state of the production process is determined by a per unit of time finished fiber product subset and from the fiber product subset a job-related actual value is calculated to the fiber product and generates a difference value from the actual target evaluation, wherein by the target specification, a product quantity and / or a production time for the given production order is determined.
  • control and planning of the production order can be carried out at an early stage with the help of just a few parameters.
  • the time unit which is relevant for the fiber product subset, could be given in coordination with the production time in hours, days, weeks or months.
  • the cumulative fiber product partial quantity can be determined after each unit of time and the actual value calculation can be used.
  • the device has a higher-level planning control unit, by means of which the actual target evaluation between the predetermined target specification determined by a production order and an actual state of the production process can be carried out.
  • the planning control unit is coupled to the plant control unit via a data connection, so that the data required for determining the actual state are accessible to the planning control unit.
  • the planning control unit enables automated planning for the production of a fiber product.
  • a fiber product both individual synthetic fibers or natural fibers and intermediates of these fibers or flat end products of these fibers, such as tissue, Knit or braids apply.
  • the device for carrying out the method in the system control unit has a means by which a fiber product partial quantity finished per unit time can be determined.
  • This means can advantageously be formed by a calculation module, by means of which an evaluation of the state variables which are continuously recorded and transmitted to the plant control unit can be carried out.
  • a weight control of the finished wound coils could be detected in a melt spinning process as state variables and summed up in the calculation module per given time unit to form a fiber product subset.
  • the planning control unit may have means which determine the required fiber product partial quantities directly from the state variables and carry out an actual value calculation.
  • the difference value resulting from the actual target evaluation can advantageously be specified as a production time difference or as a product quantity difference.
  • the actual value is calculated from the time unit, the fiber product partial quantity and the product quantity.
  • the actual value thus represents an anticipated production end time, which leads to a production time difference in the actual-target comparison with the predetermined production time. This determined production time difference must therefore be taken into account in the planning for the completion of the production order and at the beginning of subsequent production orders.
  • the difference value could be output as a product quantity difference.
  • the actual value is calculated from the fiber product partial quantity, the time unit and the production time.
  • the actual value thus represents an expected Amount of product that can be created during production time.
  • the actual-target comparison thus results in a product quantity difference, which must be based on the production order.
  • the order-related target specifications can advantageously be given up manually by an operating unit.
  • ERP enterprise resource planning
  • the target specifications can be directly automated and passed on when creating a production order at the business process level.
  • giving up the order-related target specification by the ERP control unit is particularly advantageous.
  • a preferred embodiment of the device is designed such that the planning control unit has an interface for connecting a manual operating unit and / or an interface for connecting an ERP control unit. This makes it possible to carry out a comparison between the calculated actual values and the target specification at any time within the planning control unit.
  • the difference value can be displayed both by a visualization on the operating unit or, advantageously, by a continuation to the ERP control unit.
  • the effects on subsequent production orders can thus advantageously be implemented automatically in the ERP control unit at the same time so that the business processes are updated in each case.
  • the difference value can already be calculated by a simple comparison module.
  • the difference value can then be forwarded to the ERP control unit or to an operating unit via the interfaces of the planning control unit.
  • the difference value could then trigger a change in the target specification of the current production order or a change in the target specification of the follow-on production orders.
  • follow-up production orders can also be placed directly in the planning control unit, which, after adjustment between the target specification and the difference value, creates a processing plan coordinated with the follow-up orders.
  • a processing plan could, for example, be given to the ERP control unit in order to be able to carry out a detailed planning.
  • This is also advantageous given the opportunity to counteract an impermissible deviation in the field of business processes to the effect that the target specification of the currently processing production order or follow-up production orders to change.
  • the renewed actual target evaluation leads to a new processing plan, which can be coordinated within the business process level with superordinate specifications.
  • the development of the device in which the planning control unit has a means for determining a machining plan, is therefore particularly advantageous in order to specify proposals for the further processing of the production jobs.
  • this makes it possible to provide the precursors that are processed into the fiber product in the manufacturing process; Taxes.
  • the incorporation of the processing plans created by the planning control unit into the business processes allows a high degree of flexibility with regard to the execution and execution of a large number of production orders with one production process.
  • the manufacturing process can also be divided into several independently running sub-processes.
  • a thread break within a high-speed spinning process causes the production in a spinning station is interrupted. Since the wound coils do not have the required coil weights or coil diameters at the time of yarn breakage, they could, for example, only be taken into account as C quality when determining the fiber product content. However, in order to determine a relevant for the production order fiber product subset, more example, the fiber quality determining state size are required.
  • the method variant, in which one or more state variables are detected with respect to the fiber product and / or the machine executing the processing steps are thus particularly suitable for being able to carry out automated planning in complex production processes. For this purpose, the relevant fiber product partial quantity is determined with the aid of the state variables.
  • the process variant is preferably used, in which several production orders from multiple target orders a constant comparison with the calculated actual values and thereby depending on the adjustment, the provision of precursors of the following production orders is triggered.
  • special planning algorithms can be predetermined by which, for example, priorities are predetermined.
