Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a production management system for machinery, and more particularly, to a production management system for creating a parts list required for production of an ordered machinery.
[0002]
[Prior art]
The production of machinery requires a large number of parts, depending on the size of the equipment, and for this reason, each time a machine is ordered, a list of parts required for the equipment is created, 2. Description of the Related Art There is known a production management system that enables smooth procurement.
[0003]
Here, in the case of such a production management system, the contents of the system probably involve a lot of know-how, and it is rare that the contents are disclosed. Is described as follows.
[0004]
When producing a certain mechanical device, first, a predetermined department in charge creates a drawing of each component (machine component) necessary for the configuration of the mechanical device. Then, the arranging section lists the drawings of the parts in the arranging table and passes them to the parts list issuing section. Accordingly, the parts bill issuing department has created a parts bill based on the listed arrangement table with reference to the parts bill data of the drawing, and issued an order sheet and a work instruction sheet.
[0005]
[Problems to be solved by the invention]
In the above-mentioned conventional technology, no consideration is given to the information processing procedure, and as described below, there is a problem in the complexity of the processing procedure.
[0006]
That is, in the prior art, an arrangement table is first created from the drawings created for each component and passed to another department. In other departments, the parts table is expanded by referring to the configuration information (information necessary for creating the parts table: parts information) from the arrangement table.
[0007]
However, at this time, although the drawing created for each part already has configuration information, in the related art, another form of information called an order table is newly created, and this information is sent to another department. The department that has received and received this arrangement table refers to the configuration information and expands the parts table from the arrangement table, and thus has a useless procedure in the processing.
[0008]
In this case, not only is the procedure wasteful, but also manual steps are involved in creating an arrangement table based on the configuration information and collecting detailed data of the configuration information based on the arrangement table. Therefore, the occurrence of processing errors cannot be ignored, and there are two types of information, so there is a time gap between them, and there is an unreasonable reason that a time zone in which the two types of information do not match occurs.
[0009]
SUMMARY OF THE INVENTION An object of the present invention is to provide a production management system in which a processing procedure has no waste and a highly reliable parts list can be easily obtained in a short time.
[0010]
[Means for Solving the Problems]
The object is, in a production management system that creates a bill of materials for a machine, dividing the machine into several blocks corresponding to the drawings of the machine, assigning numbers to each, and forming a tree structure with the drawings. Using the developed model block number group and the drawing group, the model block number group and the drawing data group of the mechanical device are selected and superimposed, and the parts list is automatically developed according to the system flow. You.
[0011]
At this time, the drawing and the drawing group may be constituted by electronic data.
[0012]
Similarly, the object is to provide a production management system for creating a parts list of a mechanical device, which divides the mechanical device into several blocks corresponding to the drawings of the mechanical device, assigns numbers to the respective blocks, and creates a tree structure together with the drawings. When the model block number group and the drawing data group of the mechanical device are selected and superimposed using the model block number group and the drawing group developed in If there is a match, remove the inconsistency only, and then expand the BOM, then correct the data in the inconsistency to make it consistent and put it on the same system flow. This is also achieved by not expanding the already arranged parts and expanding only the newly added parts.
[0013]
At this time, if there is an inconsistency between the model block number group linked to one arrangement object and the drawing group, a part of the data in the inconsistent part is corrected so that the partial alignment can be achieved. In this case, the parts list of the already arranged part and the inconsistent part may not be developed at this time, and only the newly compatible part may be developed in the parts table.
[0014]
Further, the above object is a production management system for creating a parts list of a mechanical device, in which a model block number and a drawing are respectively configured in a tree structure, and a block number group to be arranged is arranged for one arranged object. In a production management system in which a group of drawings to be arranged is linked so that the system can confirm its consistency, a plurality of assembly drawings (drawings) are linked to one block number and the intention of the arranger is determined. This is also achieved by specifying a drawing to be applied to the block number by selection and placing the arranged object in a workflow so that the parts table is developed.
[0015]
Further, the above object is a production management system for creating a parts list of a mechanical device, in which a model block number and a drawing are respectively configured in a tree structure, and a block number group to be arranged for one arranged object. In a production management system in which a group of drawings to be arranged is linked and the system can confirm the consistency, when the block number group is linked to an arranged object, a separately prepared schedule development system Is activated, and the date is automatically set for the block number group.
[0016]
Similarly, the above object is a production management system for creating a parts list of a mechanical device, in which a model block number and a drawing are configured in a tree structure, and a block number group to be arranged and an order are arranged for one arranged object. In the production management system in which the drawing groups to be linked are linked so that the system can confirm the consistency, when the block number group is linked to the arranged object, a separately prepared schedule development system is used. After starting and automatically setting a due date for the block number group, linking the drawing group and placing the arranged object in a workflow, the data is developed into a bill of material with an automatically set delivery date. This is also achieved in such a way.
[0017]
At this time, when the data of the drawing has a specific flag and the bill of material is to be developed, a warning is issued when the drawing is designated, and the development of the bill of material is stopped to prevent erroneous arrangement. The data of the drawing may have a change constraint flag, a warning may be issued when the drawing is revised, and an alarm may be issued to prevent the change-constrained drawing from being changed carelessly. May be added. A production management system characterized by:
[0018]
Also, at this time, in the drawing at the top of the tree structure of the drawing, a specific object is defined as a group including all the drawings immediately below the drawing instead of the drawing, and May be provided with a function of acting as a set drawing that summarizes
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a production management system according to the present invention will be described in detail with reference to the illustrated embodiments. Here, first, FIG. 1 is a block diagram of a production management system according to an embodiment of the present invention, schematically showing a system flow in the system.
[0020]
First, the system flow is started when a production instruction for a certain mechanical device is issued, for example, by receiving an order, and a production management number representing the production instruction for the mechanical device is given (process 1).
[0021]
At this time, the production control number may have different names depending on the production mode. However, in this embodiment, the production control number is not limited to the term “production control number”, but is referred to as “production control number”. A suitable name may be given as appropriate.
[0022]
When the production control number is given in this way, an object on the system corresponding to the production control number is raised, and the production control number is attached (associated) to the model block number group (process 2), and is applied to the production control number. The block number group to be performed is recognized in the parts table development system, and a parts preparation schedule and a parts procurement designation date for each block number are determined in a separately prepared schedule development system.
[0023]
Here, this schedule arrangement system sets a date on which the procurement of the part should be performed for the standard block number BOM prepared in the standard BOM based on a schedule for starting the assembly of the main parts used in the block. Data is set in advance so that a component is calculated and calculated at an optimal time (Just In Time) with respect to a component to be developed later.
[0024]
The standard BOM (Bill of Material) at this time is a storage device in which a standard block number BOM based on electronic data and a standard drawing BOM based on electronic data are stored in advance. The figure is described as follows.
[0025]
In recent years, the spread of CAD (Computer Aided Design) has been remarkable, and data diagrams (drawings using electronic data) have been extremely easily obtained. Nevertheless, this CAD is merely used as a tool for creating drawings. If used, the data at the corner is buried and cannot be used effectively.
[0026]
Therefore, in this embodiment, it is assumed that a drawing is created by CAD, and when a data diagram is created, all the used data is used as it is in the form of data, so that a process of drawing on paper to make a drawing is prevented. -ing
[0027]
Returning to the description of the standard BOM, here, first, the standard block number BOM is assumed to be various standard mechanical devices that are expected to receive orders in advance, and these mechanical devices are represented by some blocks corresponding to the drawings. This is data obtained by assigning a number to each to make a model block number, which is expanded into a tree structure.
[0028]
Next, the standard drawing BOM, which is also stored in the standard BOM, is assumed for various standard mechanical devices that are expected to receive orders in advance, and various components used for each assumed mechanical device. Is a data obtained by expanding the data diagram in a tree shape together with the corresponding configuration information.
[0029]
By the way, it is desirable to create a data diagram by CAD at this time so that the data diagram can be used commonly for various mechanical devices. However, if all the tree expansions are performed using only the data of the drawing, there is a possibility that the sharability is impaired.
[0030]
Therefore, in this embodiment, as described above, each mechanical device is divided into several blocks corresponding to the drawings, and numbers are assigned to the respective blocks to form model block numbers, which are expanded in a tree structure.
[0031]
In this way, the drawings of the mechanical devices are all made of electronic data (data diagrams) and are used as the only data, thereby eliminating any similar or pseudo data and simplifying them. All the drawings are put together in a complete tree structure so that the configuration of the complete device is included, whereby the first drawing to the last drawing are related.
[0032]
In order to arrange production of a specific mechanical device, in this embodiment, first, a model block number group constituting the mechanical device is selected, a drawing data group is superimposed on this block number, and conditions are met. Then, the set of mechanical devices can be specified by the block number group and the drawing group, and as a result, the parts list can be automatically developed by tracing the data.
[0033]
Returning to FIG. 1, a drawing group representative of the model is selected from the standard block number BOM in the standard BOM, and attached to the production control number. Be expanded.
[0034]
At this time, in the assembly drawing composed of a plurality of individual parts, the standard block number in which the drawing is to be used is declared in advance, and when the tree is expanded from the drawing, the tree specified by the drawing and the It is possible to confirm the consistency of both of the tree of block numbers declared by the model block number group.
[0035]
Then, in a state where the consistency is confirmed in this way, the tree composed of the block numbers is compared with the tree formed by drawing development, and parts that are matched are developed, and all drawings are child drawings. The development is repeated until (drawing at the end of the tree), that is, until all the parts are covered. When all the drawings become child drawings, the development is completed, and the representative drawing is completed (process 3). .
[0036]
Here, when checking the state where the parts have been developed before the actual arrangement, the state can be checked on the display or printed out. The confirmation method at this time can be arbitrarily selected according to the convenience of the production system.
[0037]
Next, in a state where the model block number group and the representative drawing are pasted, the production control number object is put on the arrangement object and put on the approval workflow, and an approval request for the object to be arranged is posted in the workflow. Then, this is notified to the person to whom the approval authority is assigned by means such as e-mail (Process 4).
[0038]
As a result, when the approval operation is performed on the BOM, the gate of the prepared BOM opens, and the data including the schedule development result is sent to the BOM issuing system, and the data is automatically sent. A parts list will be issued.
[0039]
FIG. 2 shows an example of a tree expansion of data representing the standard block number BOM in this embodiment. The number 000 at the left end indicates a data group of the mechanical device, and the number group at the right end is the lowest number group. Represents.
[0040]
Here, the numbers 111, 112, 113, and 114 are the drawing data of the parts having the functions integrated in the minimum unit or the work data integrated in the minimum unit. , 112, 113, and 114 correspond to drawings having at least one piece of data under each.
[0041]
In addition, it is shown that these numbers 111, 112, 113, and 114 are represented by the number 110 here, and that the units that are slightly broadened by the numbers 110 and 120 are combined by the number 100. Have been. The same applies to numbers 200 and 300 (hereinafter abbreviated). Finally, the number 000 indicates the configuration of all the mechanical devices.
[0042]
Next, FIG. 3 shows the tree expansion of the data in the standard block number BOM on the drawing data. Here, in order to make it easy to understand, the drawing is shown as a two-dimensional display as an example, and the title is shown on the drawing. The column and the component information column are simultaneously displayed.
[0043]
However, the embodiment of the present invention is not limited to this. For example, a file management method known as electronic data may be used, and the data may be separately managed without being integrated with the drawings.
[0044]
In FIG. 3, reference numerals 110 to 113 represent screens corresponding to the block numbers in FIG. 2, and each drawing is provided with a title column at the lower right, in which the drawing number, creator name, history, etc. are shown. It is recorded and managed, and a component information column is provided at the upper right.
[0045]
At this time, in FIG. 3, this part information column is shown in more detail in the drawing of No. 110, and here, each item of “Apply”, “Part number”, “Drawing number” and “Article” is shown in four columns. It is shown that it is provided across.
[0046]
First, in the item “part number”, the number of drawings constituting the drawing of the number 110 is described. As an example, in this figure, since the part numbers 1 to 6 are described here, in the case of the drawing of this number 110, it is indicated that it is formed by a set of six sheets. ing.
[0047]
At this time, in the part number 5, since the item “drawing number” is B32145 and the item “application” is 2, in the case of the part unit with the number 110, the part unit represented by the drawing of the figure number B32145 is 2 It turns out that it is used.
[0048]
Next, on the right side of the drawing of the number 110, the six drawings forming the drawing are expanded in a tree, and the drawings of the numbers 111 to 113 (the drawings of the numbers 114 to 116 are omitted). It is shown as Here, the drawing A12345 designated by the part number 1 is the drawing of the number 111, and the drawing B23456 similarly designated by the part number 2 is the number 112.
[0049]
In addition, the drawings 111 to 113 (the drawings of numbers 114 to 116 are omitted) are shown below the drawing of the drawing 110 and the drawing of the drawing 111. It is shown that the drawings No. to 113 are composed of a plurality of drawing groups, and one drawing in the drawing group can be arbitrarily called for each drawing.
[0050]
Therefore, according to this embodiment, for a repeat order (reorder for the same model) of a machine in which all the standard BOMs are registered in advance, the model block is added to the production arrangement number (production control number). By dropping the number group and the representative drawing group and going through the steps of arrangement / approval, all production arrangements are completed, and a parts list can be issued.
[0051]
Also, if the customer's unique request is included in the production instruction, arrangements for parts with unspecified specifications are temporarily reserved, and models within the range where the specifications are determined from the model block number group By selecting a block number, pre-arranging it in the same arrangement form as described above, and later confirming the specification, placing it on the same arrangement route allows a parts list to be issued.
[0052]
Here, in the above embodiment, when the drawing data has a specific flag and the bill of material is to be expanded, a warning is issued when the drawing is designated, and the developing of the bill of material is stopped. Another embodiment can be provided by adding a function of preventing misordering.
[0053]
Also, another embodiment is provided in which the drawing data has a change constraint flag, a warning is issued when the drawing is upgraded, and an alarm is issued so that the change-constrained drawing is not inadvertently changed. You can also.
[0054]
Similarly, a specific object is defined not as a drawing, but as a group that includes all the drawings directly below it, and the entire drawing is organized as a group that summarizes the whole at the top of the tree structure of the drawing. Another embodiment may be provided so as to have a substitute function of a set drawing.
[0055]
【The invention's effect】
According to the present invention, since the production system is configured as described above, for a repeat order of a machine in which all standard BOMs are registered, the model block number group and the model block number group are added to the production management number. By simply dropping the representative drawing group and going through the arrangement / approval step, all production arrangements are completed and a parts list can be issued.
[0056]
In addition, at this time, those that have already been arranged are passed, and the system recognizes only new arrangements and automatically issues them as a bill of materials, so that erroneous arrangements and duplicate arrangements that occur in the case of manual operation are suppressed, In addition, it is useful for the innovation of the arrangement business that the business is processed at the transmission speed of the IT tool.
[0057]
Further, since the arrangement result can be stored and managed as it is, there is no need for human intervention in the history management, and the effect that the data storage management can be achieved with high accuracy can be obtained.
