By the way, in actual work processing steps of a production line (production process) composed of a plurality of processing steps, work delays in the pre-processing step and the post-processing step, and conveyance of work-in-process materials between the pre-processing step and the post-processing step. Variations in various work processing processes between pre-processing and post-processing processes, such as the degree of tightness of storage equipment inventory due to capacity, and interruption work such as rework due to quality defects of manufactured products (regular Depending on the situation, there may be a situation where the production plan originally planned cannot be observed.

For such irregular situations, if the work procedure in each processing step is changed, or if there is an emergency treatment such as a work delay in the post-processing step, the work-in-process material that has undergone the pre-processing step is separated. It is necessary to take various measures such as dealing with occasional changes such as retreating to other storage facilities and re-creating production schedules and logistics plans.
In order to avoid such problems, unloading work from a plurality of pretreatment processes to storage facilities is performed based on human work in which operators controlling each pretreatment process make adjustments related to unloading work. ing.

In order to eliminate such an operator's load, the technique of Patent Document 1 and Patent Document 2 is used to effectively carry out the work-in-process material from the pretreatment process to the storage facility, that is, the optimum process of the work-in-process material. Consider creating a plan.
For example, Patent Document 1 presents information on the inventory status of a base (storage facility) to an operator of a distribution center or factory, but the amount of information is too small with only this inventory information. It is not possible to cope with the occurrence of a regular situation.

  Further, Patent Document 2 discloses information on the stock status of storage equipment and other information obtained from the stock information in accordance with the “rules” relating to storage equipment registered in advance, but the target storage Since the conditions of the facilities are various and constantly changing, it is difficult to organize and maintain the rules accurately. Further, even if the rules can be organized and maintained, it takes time, so it is almost impossible to actually operate Patent Document 2.

That is, Patent Document 1 and Patent Document 2 respond to irregular conditions in the production line by presenting necessary and sufficient information regarding storage facilities to operators of production lines such as factories and distribution centers. It is not a technology that can.
Therefore, in view of the above problems, the present invention includes a plurality of pieces of information such as information indicating the status of the storage facility, temporal transition information based on the information, and acceptable information on the storage facility based on the processing capacity of the post-processing process. An object of the present invention is to provide an operation information providing system capable of efficiently carrying out work from a pretreatment process to a storage facility by providing and sharing.

In order to achieve the above-described object, the present invention takes the following technical means.
The operation information providing system according to the present invention includes a plurality of preprocessing steps for performing a predetermined process on a work in progress material, a storage facility for transporting and storing the work in progress material through the pretreatment step, and the storage A post-processing step for performing a predetermined process on the work-in-process material carried out from the facility, and an operation information providing system in the production line, wherein the operation information providing system can be confirmed by an operator of the pre-processing step A display that includes primary information indicating an inventory status of the work-in-process material in the storage facility, secondary information indicating temporal transition of the primary information, and processing in the post-processing step. Each of the operators operating the plurality of pre-processing steps by the display unit. The primary information to the tertiary information are displayed by the display unit. Characterized in that it has become can be shared for.

Preferably, as the primary information, the delivery date of the work-in-process material stored in the storage facility is displayed in different colors so that the work-in-process material performing the same work in the post-processing step can be identified among the work-in-process materials. It should be displayed.
Preferably, the secondary information may be unloading progress information indicating a delay in delivery date of the work-in-process material stored in the storage facility with time.

Preferably, the tertiary information evaluates a processing speed of the post-processing step, and sets a threshold value of the amount of the work-in-process material acceptable to the storage facility based on the evaluated value and the secondary information. The set threshold value may be provided as an unloading index to the preprocessing step.
Preferably, when the value of the individual information of the work-in-process material carried out from the pre-processing step is out of the threshold value of the tertiary information, the display unit warns the operator of the pre-processing step. Should be notified.

  According to the operation information providing system according to the present invention, a plurality of information such as information indicating the status of the storage facility, time transition information based on the information, and receivable information of the storage facility based on the processing capacity of the post-processing step are stored. By providing and sharing, it is possible to efficiently carry out work from the pretreatment process to the storage facility.

It is the conceptual diagram which showed typically the operation information provision system which concerns on this invention. It is the figure which showed an example of the primary information-tertiary information displayed on the screen of a display monitor. It is the figure which graphed the tertiary information displayed on a display monitor.

Hereinafter, an embodiment of an operation information providing system according to the present invention will be described with reference to the drawings.
The operation information providing system 1 according to the present invention assists in smoothly carrying a product carrying work in accordance with a physical distribution process when various products are carried on a physical distribution line in a factory. For example, a process (production line 2) for continuously processing various work-in-process materials (original materials and products) can be considered.

As shown in FIG. 1, the production line 2 of the present embodiment is a facility in which a storage facility 4 exists between a plurality of pretreatment steps 3 and posttreatment steps 5. In describing the operation information providing system 1 of the present embodiment in detail, it is assumed that three pre-processing steps 3 of the production line 2 are arranged in parallel, and that the post-processing steps 5 are arranged in series. .
In FIG. 1, the pretreatment process 3 of the production line 2 is designated as an A process 3a, a B process 3b, and a C process 3c in order from the upper side of the drawing, and the post-treatment process 5 is arranged in order from the left side of the drawing. And

  The production line 2 of the present embodiment temporarily stores, for example, a pretreatment process 3 including A process 3a to C process 3c arranged in parallel and a work-in-process material carried out from the pretreatment process 3, and a post-treatment process. Equipment having storage equipment 4 (work-in-process, warehouse) for transporting work-in-process materials to post-processing process 5 for each manufacturing order, and post-processing process 5 consisting of D process 5d and E process 5e arranged in series It is.

In such a production line 2, in each pretreatment process 3 of the A process 3a to the C process 3c, the work-in-process material is subjected to a predetermined process until it can be processed in the post-process process 5. The work-in-process material processed in each pretreatment process 3 is temporarily stocked in the storage facility 4 until the order (process order of work-in-process materials) to be transferred to the D process 5d (post-processing process 5) comes.
Then, the work-in-process material that has been transferred to the D step 5d is transferred to the D step 5d and subjected to a predetermined process. The work-in-process material processed in the D process 5d is carried out to the downstream E process 5e. The work-in-process material conveyed to the E process is further subjected to a predetermined process.

Thus, in the production line 2 used in this embodiment, the work-in-process material is changed to A process 3a to C process 3c (pretreatment process 3) → storage facility 4 → D process 5d (post treatment process 5) → E process 5e. Production is advanced while continuously transporting in the order of (post-processing step 5), and different products are finished for each user.
Now, when a product is manufactured on the production line 2 described above, a plurality of work-in-process materials are processed in a preset order (such as delivery date order). This work-in-process material is associated with contents (individual information) such as product name, model number, order of delivery, and processing method. The production line 2 performs a predetermined process on the work-in-process material in the A process 3a to the C process 3c based on the individual information for each work-in-process material, and performs a predetermined process on the work-in-process material in the D process 5d.

  In order to perform a predetermined process on the work-in-process material in the D process 5d (post-process process 5), for example, in the storage facility 4, the process method is almost the same, or the individual work-in-process materials have the same delivery date. The work in progress material is selected in consideration of the information, and the work in progress material is carried out from the storage facility 4 to the D process 5d. That is, in order to perform a predetermined process on the work-in-process material in the D step 5d, it is important that the stock status of the storage facility 4 for temporarily storing the work-in-process material is steadily decreasing.

However, the trend of inventory reduction of the storage equipment 4 for temporarily storing work-in-process materials is not smooth, that is, there is often a work delay in the D process 5d.
For example, as shown in FIG. 1, in-process material A is manufactured in A process 3a (pretreatment process 3), in-process material B is manufactured in B process 5b, and in-process material C is manufactured in C process 5c. The work-in-process material A through work-in-process material C that have finished the A process 3a through the C process 5c are temporarily stored in the downstream storage facility 4.

  However, if the inventory decrease of the storage facility 4 is not smooth, the storage facility 4 will be saturated if it is attempted to transport the in-process material A to the in-process material C that have finished the A process 3a to the C process 5c to the storage facility 4 at the same time. Since any of the work-in-process material A to work-in-process material C cannot be temporarily stored, the production line 2 may be stopped. In such a case, each operator involved in the A process 3a to the C process 3c may consult with the operator of each pretreatment process 3 (adjustment of conveyance) to determine the order of conveying the work-in-process material to the storage facility 4. It becomes essential.

That is, the operator who controls the A process 3a to the C process 3c determines the order of transporting the work-in-process material to the storage facility 4 in consideration of the inventory status of the storage facility 4 and the progress status of the subsequent D process that digests the inventory. It is necessary to do. However, since the inventory status of the storage facility 4 changes every moment, it may be difficult to grasp the inventory status of the storage facility 4 in real time.
Therefore, the operation information providing system 1 according to the present embodiment, which will be described below, displays the stock status of the storage facility 4 in real time to an operator who controls the A process 3a to the C process 3c so that it can be shared. The order in which the work-in-process material is conveyed to the storage facility 4 is determined.

Hereinafter, the operation information provision system 1 which concerns on this embodiment is demonstrated based on a figure.
The operation information providing system 1 of the present embodiment is a support system in the production line 2 and includes each process [A process 3a to C process 3c (pre-processing process 3), D process 5d, E process 5e (post-processing process 5). )]) And the like, and information on the inventory status of work-in-process materials in the storage facility 4 are input, and the information processing apparatus calculates the amount of work-in-process materials to be transported to the storage facility 4 based on the information. (Pro-con). Furthermore, the display 6 (display monitor) which displays the information collected by the information processing apparatus (not shown), for example, the information on the stock status of the work in progress in the storage facility 4, is provided.

The display monitor 6 is provided for each of the A process 3a to the C process 3c, and can be confirmed by each operator of the A process 3a to the C process 3c. The display monitor 6 may be provided in each of the D process 5d and the E process 5e, and the operator of the D process 5d and the E process 5e may be able to confirm.
That is, the display monitor 6 may be provided in every process provided in the production line 2. Examples of the display monitor 6 include a liquid crystal monitor and a CRT monitor.

As shown in FIG. 2, the display monitor 6 provided in the operation information providing system 1 includes primary information indicating the stock status of work-in-process materials in the storage facility 4 and secondary information indicating temporal transition of the primary information. And tertiary information that is information relating to the processing capability of the post-processing step 5 is displayed.
The display monitor 6 allows primary information to tertiary information to be shared with each operator who operates the pretreatment process 3 (A process 3a to C process 3c). The primary information to the tertiary information according to the present invention may be sharable for all operators who are engaged in the production line 2.

Hereinafter, details of the primary information to the tertiary information displayed on the display monitor 6 and shared among the operators will be described.
The primary information displays the loading state of the work-in-process material temporarily stored in the storage facility 4 and the delivery date of each work-in-process material.
As shown on the upper left side in FIG. 2, the primary information indicates the placement status of work-in-process materials temporarily stored in storage areas (storage area A1 to storage area C1 and the like) in the storage facility 4. It is displayed on the screen of the display monitor 6 by a figure W (bar graph) or the like.

The work-in-placement status is “storage information” indicating that the work-in-process A (article A) carried out from the step A 3a is placed in the storage area A1 in the storage facility 4 in order from the left side of FIG. A1 ", B
“Storage information B1” indicating that the work-in-process material B (article B) carried out from the step 3b is placed, and that the work-in-process material C (article C) carried out from the C step 3c is placed. "Storage information C1" is shown.

Further, “storage” indicating that a place (not shown) different from the pretreatment process 3, for example, a work-in-process material Z introduced into the posttreatment process 5 without performing the pretreatment process 3 is placed. Information Z1 "is shown.
In the storage information A1, figures W imitating seven work-in-process materials A stacked in the storage area A1 are displayed in the order in which they are stacked. Further, the storage information B1 displays the figures W imitating the 10 work-in-process materials B stacked in the storage area B1 in the order in which they are stacked. Further, the storage information C1 displays the figures W imitating the three work-in-process materials C stacked in the storage area C1 in the order in which they are stacked.

In the storage information Z1, figures W imitating the two work-in-process materials Z stacked in the storage area Z1 are displayed in the order in which they are stacked.
Below the storage information A1 to storage information Z1 indicating the placement status of the in-process materials A to Z, the in-process materials A to Z stored in the storage areas A1 to Z1 (storage facility 4). Are displayed in different colors, and among the in-process materials A to Z, the in-process materials performing the same work in the post-processing step 5 are displayed so as to be identifiable.

As shown in FIG. 2, each figure W indicating the work-in-process material A to the work-in-process material Z is colored with a predetermined color according to the margin of delivery time (room for completing the work). The delivery date of the work-in-process material exists in the information processing apparatus that manages the post-processing process 5 (D process 5d, E process 5e, etc.), and the delivery date information is displayed instantaneously (in real time) on the display monitor 6. It has become.
Regarding the color indicating the margin of delivery date, for example, the color W (the graphic W indicating the work-in-progress material that requires urgent work) with the shortest delivery time, such as a color that can be clearly visually recognized (in FIG. 2) The shaded part) is colored and the delivery date is delayed (medium urgency). The figure W indicating the work in progress is a “warm color” color such as orange (in FIG. 2, the diagonally right hatched part) It is good to color. In addition, regarding coloring, if the deadline of a delivery date can be confirmed, there will be no limitation in coloring in particular.

  In addition, below the storage information A1 to storage information Z1 indicating the placement status of the above-described work-in-process material A through work-in-process Z, details of the delivery date information of work-in-process material A through work-in-process Z indicated by the simulated figure W Is displayed. Specifically, from the upper side of the primary information display screen in FIG. 2, the total number of work-in-process materials placed, the number of work-in-process materials to be carried out, the number of work-in-process materials whose delivery date is delayed, and the delivery date The number of work in progress with a high degree of urgency is displayed.

In this way, the work-in-process material placed in the storage facility 4 is color-coded according to the delivery date, and by displaying the details of the delivery date information of the work-in-progress material, the delivery date of the work-in-progress material can be easily grasped. it can.
The secondary information is carry-out progress information that indicates a delay in the delivery date of work-in-process materials stored in the storage facility 4 over time.

  As shown in the upper right side of FIG. 2, the secondary information includes, for example, a time axis (horizontal axis) in which daily work is divided every 8 hours, and delays for all work materials stored in the storage facility 4. A graph with the vertical axis showing the ratio of the number of sheets (number of sheets delayed in delivery / number of all work in progress) is displayed, the status of delay in delivery (delayed sheet ratio), the reference value of the status of delay in delivery, and the production of work in progress The cost is displayed on the screen of the display monitor 6.

From this secondary information, each operator of the A process 3a to the C process 3c (pre-processing process 3) can grasp the inventory status in the storage facility 4, that is, the status of the delivery delay of the work in progress. That is, each operator of the A process 3a to the C process 3c can determine whether or not the work of the D process 5d (the post-processing process 5) is appropriately performed.
The tertiary information evaluates the processing speed of the post-processing step 5, sets a threshold value of the amount of work-in-process material that can be accepted by the storage facility 4 based on the evaluated value and the secondary information, and sets the threshold value as A This is information to be provided as an unloading index for the steps 3a to 3c (pretreatment step 3). In other words, the tertiary information is information regarding the processing capability of the post-processing step 5.
As shown in the lower left side of FIG. 2, the tertiary information includes, for example, an item indicating “currently, whether or not the storage facility 4 can accept work in progress”, “delivery date of work in progress that can be accepted” An item indicating “expiration date”, an item indicating “reception time of storage facility 4”, and an item indicating “amount of work in progress that can be received” are displayed on the screen of the display monitor 6.

  When displaying the tertiary information, the information processing device first stores the secondary information based on the transition of the work-in-process material inventory in the storage facility 4 (whether the work-in-process material is being produced as planned). It is calculated whether or not the facility 4 can accept the work-in-process material. When it is calculated that the storage facility 4 can accept the work-in-process material, the delivery date information of the work-in-process material that has undergone the A process 3a to the C process 3c is obtained from the primary information and the current processing capacity of the D process is obtained. get.

Based on this primary information and secondary information, for example, the storage facility 4 is information (storage) that can be accepted if the delivery date of the work-in-process material is from the present three days ago (N = 3, threshold) The due date of work-in-process materials that can be accepted by the facility 4 is calculated. Moreover, the reception time of the storage facility 4 set in advance is acquired.
The carry-out index (tertiary information) calculated in this way is displayed on the display monitor 6 provided in the A process 3a to the C process 3c.

  Generally, due to differences in manufacturing conditions, the order of processing in the A process 3a to the C process 3c does not match the order of processing in the D process. If there is a margin in the storage, if the delivery date of the previous one is brought in, there is a possibility that the margin of the storage will be reduced, the long-term staying material will rise, and the next one with a shorter delivery date cannot be brought in. Therefore, it is useful to prevent an urgent take-in of an in-process item to indicate “the deadline for delivery of in-process materials that can be accepted” according to the situation of the storage.

From the above, by displaying the calculated tertiary information in addition to the primary information and the secondary information, each operator in the pretreatment process 3 (A process 3a to C process 3c) is notified of the storage facility 4 An accurate current situation can be provided, and each operator can share the exact current situation of the storage facility 4.
That is, each operator of the pretreatment process 3 determines whether or not the work-in-process material can be carried out to the storage facility 4 only by checking the display monitor 6 on which the current status of the storage facility 4 is displayed. can do.

  In addition, the value of individual information (property: for example, the period until delivery date) of the work-in-process material carried out from the preprocessing step 3 deviates from the threshold value of the tertiary information (for example, N = 3, accepts only within 3 days for delivery). If this happens, an alarm is displayed on the display monitor 6 and the operator of the pretreatment process 3 is notified, so that the operator of the pretreatment process 3 reliably carries out the work-in-process material to the storage facility 4. It can be determined whether or not it is possible.

By the way, the tertiary information shown in FIG. 2 is displayed as character information on the display monitor 6 arranged in the A process 3a to the C process 3c and notified to the respective operators in the A process 3a to the C process 3c. May be displayed.
As shown in FIG. 3, for example, secondary information indicating a temporal transition of inventory in the storage facility 4 (whether or not the work in the storage facility 4 is smoothly made) and a D step 5d (post-processing step) Based on the processing capability of 5), tertiary information indicating a decrease prediction of the inventory in the storage facility 4 may be displayed on the display monitor 6 as a graph.

As shown in FIG. 3, when a graph is displayed that decreases rapidly as it goes to the right (time elapses), “only in-process materials are delivered up to 3 days before (N = 3) “Acceptable” may be displayed.
As described above, by using the operation information providing system 1 according to the present invention, information indicating the status of the storage facility 4, temporal transition information based on the information, storage based on the processing capacity of the post-processing step 5 A plurality of pieces of information such as information that can be accepted by the facility 4 can be provided and shared, and the work for carrying out from the pretreatment process 3 to the storage facility 4 can be performed efficiently.

In the description of the operation information providing system 1, the preprocessing process 3 and the postprocessing process 5 of the production line 2 have been described without specifying them. It is assumed that it is a casting process, and the post-processing process 5 may be a rolling process.
Further, even if the pretreatment process 3 is a rolling process and the posttreatment process 5 is a transportation process for transporting a final product stored in the storage facility 4 (warehouse) to a predetermined place by a transportation means such as a truck. Good. Further, the present invention can be applied to a distribution center that carries out final products to the outside.

In other words, the production line 2 that can be applied to the operation information providing system 1 of the present invention is a facility that transports each work-in-process material transported from a plurality of processes to a subsequent process via the storage facility 4, Applicable to all production lines 2.
In particular, in the embodiment disclosed this time, matters that are not explicitly disclosed, for example, operating conditions and operating conditions, various parameters, dimensions, weights, volumes, and the like of a component deviate from a range that a person skilled in the art normally performs. Instead, values that can be easily assumed by those skilled in the art are employed.
