  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an article storage plan formulation system according to one embodiment of the present invention. The article storage plan formulation system according to the present embodiment is realized by software on a computer system. However, if it is shown as a functional configuration separately for each process that can be distinguished from others, the system is composed of the following parts. It is held on a storage medium of a large-capacity storage device such as one or a plurality of hard disks, and consists of a master data file 10 that holds various data to be described later, a display, a pointing device such as a mouse, and a keyboard. 2 is displayed on the display of the human machine interface (HMI) 20 as shown in FIG. 2 to designate an article to be planned for the placement plan, and the shape is called. Further, the production process is started from the master data file 10. The location plan screen 31A of the production site at a certain date and time above is expanded, the shape of the corresponding item is called by the item number, and a movement command is obtained by dragging and dropping it with the pointing device of the HMI 20 to obtain the location plan screen. Place it in a suitable place on 31A and It has a location planning unit 30 to develop the yard plan by specifying the loading date and carry-out date and time of the article. Although details will be described later, the layout of the article storage area at the date and time of the storage plan formulated by the location plan formulation unit 30 can be displayed on the HMI 20 as a location map 32 as shown in FIG. 3 and printed out. .

  The storage planning system according to the present embodiment further generates a bar chart 41 shown in FIG. 4 corresponding to a calendar for each article for which a storage location and a storage period have been determined, and displays the schedule display processing unit on the display screen. 40. An animation display processing unit 50 is provided for displaying an animation of the movement of an article specified before or after designating an individually designated article or a certain date and time in a process period.

  In the master data file 10, as shown in FIG. 5, the names, numbers, shapes schematically representing the shapes of the articles, the dimensions of the height and width, and the weight dimensions, which have already been placed, are already placed. Is determined, the upper left coordinates (x1, y1), the lower right coordinates (x2, y2), and the date and time of delivery to the floor of the production site targeted by the system (scheduled start date and time) The data related to the carry-out date / time (scheduled end date / time) is held as the quantity master file 11.

  As shown in FIG. 6, the master data file 11 also includes mobile equipment existing on the production floor floor, fixed equipment name (number), shape, upper left coordinates, lower right coordinates, Data related to the existence period is held as the equipment master file 12.

  In addition, since the master data file 10 lifts and moves the article with the lifting equipment, the lifting weight of the lifting equipment installed at each place on the floor of the production site as shown in FIG. The lifting weight master file 13 registered in association with the coordinates is held.

  As shown in FIG. 8, the master data file 10 holds, as a load-bearing master file 14, data that associates the load-bearing per unit area of the floor with the coordinates of the place. Further, as shown in FIG. 9, the master data file 10 holds, as a height master file 15, data associated with the location coordinates regarding the height restriction of each place on the floor of the production site.

  Next, an article storage plan formulation method by the article storage plan formulation system configured as described above will be described.

[Create and register master data]
In the quantity master file 11 of the master data file 10, as shown in FIG. 5, the shapes, vertical and horizontal heights, and weights of the names, numbers, and shapes of the various articles that are the targets of the placement plan of the system are schematically shown. Data relating to the dimension, delivery date, delivery date / time (scheduled start date / time) and delivery date / time (scheduled end date / time) to the storage floor of the production site targeted by the system is registered as the quantity master file 11. If a new article needs to be registered, it can be newly registered at any time.

  In addition, in the equipment master file 12 of the master data file 10, as shown in FIG. 6, the upper left of the coordinates of the existing fixed equipment, equipment name (number), shape, and location of the existing equipment on the floor of the production site. , Register the data related to the lower right coordinates and existence period.

  Further, as shown in FIG. 7, the lifting weight master file 13 of the master data file 10 registers the lifting weight that can be lifted by the lifting equipment installed on each floor of the production site in association with the coordinates of the place. . For example, since this place can use only a lifting device having a lifting weight of less than 2t, a place having a lifting weight restriction that only articles having a weight of less than 2t can be placed is designated.

  Further, as shown in FIG. 8, in the load bearing master file 14 of the master data file 10, data relating to the load coordinates per unit area of each place on the floor is registered.

  In the height master file 15 of the master data file 10, as shown in FIG. 9, data related to the height coordinates of each place on the floor of the production site is registered.

  It should be noted that in the production factory building, distribution warehouse, and other places where the present system has been introduced once, the type of the majority of the articles handled in the place does not change. Similarly, it is usual that the storage plan screen, the weight data, the load resistance data, etc. of the article storage are not changed. Once registered in the master data file 10, it can be used for new process management. And if the handling of a new article is necessary for the production of a new product, the article name, number, shape, dimension, etc. can be registered in the quantity master file 11 for each new article, Thereby, the creation effort of the master data file 10 is reduced.

  In the planning of the placement plan, in the system of the present embodiment, if the “place drawing input” is selected while the open screen D1 shown in FIG. 10 is displayed on the display of the HMI 20, the placement plan input screen shown in FIG. 31 can be displayed and it can transfer to an article storage plan process. Further, if “place drawing output” is selected from the open screen D1 shown in FIG. 10, the place drawing output setting screen D2 shown in FIG. 11 is developed. By designating the scheduled date and time and designating the output interval, the location map 32 of the corresponding date and time as shown in FIG. 3 can be displayed. Further, if “schedule display” is selected from the open screen D1, the schedule display setting screen D3 in FIG. 12 is developed. As shown in FIG. 4, the display period is designated on the schedule display setting screen D3. The schedule can be displayed on a simple bar chart. Furthermore, by designating “animation display” from the open screen D1, the animation display setting screen D4 shown in FIG. 13 is developed. Therefore, the name of the article to be displayed is designated or displayed on the animation display setting screen D4. By designating the start date and time and the display end date and time, the movement of the designated article or the movement during that period can be displayed as an animation (51 in FIG. 1).

[Goods storage plan]
When formulating a placement plan for an article, data related to the article is called from the quantity master file 11 by designating the name of the article on the placement plan input screen 31 as shown in FIG. Also specify the call-in date / time and the carry-out date / time as the scheduled start date / time and the scheduled end date / time. As a result, the shape 34 appears at the initial position of the place planning screen 31A as shown in FIG. The place planning screen 31A as shown in FIG. 14 shows the layout 35 of the storage floor and the shape of the article whose place has already been determined by the planning target date and time, the article, the equipment, etc., which have been previously determined. The state where 36 is placed in the corresponding place is displayed.

  An operation of moving and arranging the shape 34 of the article to be placed on the floor layout 35 to an appropriate place on the floor layout 35 by dragging and dropping with the pointing device of the HMI 20 is performed. Here, a case is shown where the cursor 37 is placed on the shape 34 that appears in the lower right of the place plan screen 31A and dragged, moved to the upper left position of the floor layout 35, and dropped. And this place to drop, or other items that have been placed in the vicinity around it will interfere, or will be carried in later, but other places already registered in that place in the place plan If it can be confirmed that there is no danger of interference due to the article, it is allowed to drop to the place, and the place is confirmed.

  The plan to place the certain article A in the certain place PL_A is allowed during the placing period from the date when the article A is carried in until the date when the article A is mounted on the product or used for product production. It is an essential condition that there is no other article or equipment in the area where the place PL_A or surrounding articles interfere with each other. At the same time, it is also determined whether the load-bearing capacity of the corresponding place is allowed, whether the height restriction is applied, and whether the lifting weight restriction can be cleared. For these determinations, the physical quantity master file 11, the equipment master file 12, the lifting weight master file 13, the load bearing master file 14, and the height master file 15 of the master data file 10 are referred to.

  The determination flow of time overlap and place overlap is as follows. When the place plan formulation unit 30 designates the carry-in date / time and the carry-out date / time as the scheduled start date / time and the scheduled end date / time on the placement plan input screen 31 shown in FIG. The location drawing 32 of the scheduled start date and time in the state established so far with reference to the master file 11 is displayed on the display as the location planning screen 31A, the shape is called, and the location planning screen 31A is displayed as shown in FIG. The shape 34 is called and displayed at the initial position. In this state, if the shape 34 is dragged with the cursor 37 and moved to a vacant place on the floor layout 35 and dropped, the processing of the flowchart of FIG. 15 is started.

  Step ST1: As the coordinates on the floor layout 35 where the shape 34 is dropped, the upper left and lower right coordinates of the shape 34 at the corresponding location are acquired. In the parking floor layout 35 shown in FIG. 14, the upper left corner is determined as the origin (x = 0, y = 0). The drop position of the shape 34 of the article A is specified by the upper left coordinates (x1, y1) and the lower right coordinates (x2, y2) with respect to the origin.

  Steps ST2 to ST4: Based on the upper left and lower right coordinates of the shape 34, refer to the lifted weight master file 13 and determine from the weight of the article A to determine whether it can be carried into the corresponding place. To do. If the limit is exceeded, an alarm is output and a message is output. Here, for example, along with the output of a beep sound, the shape 34 is blinked, and a message “A lift weight limit will be applied. The place needs to be changed.” Is displayed by a balloon.

  Steps ST5 to ST7: It is also determined with reference to the load bearing master file 14 whether or not the load bearing limit of the corresponding location is violated. If the load capacity is violated, an alarm is output and a message is output. Also here, for example, together with the output of a beep sound, the shape 34 is blinked, and a message “A load limit is applied. The place needs to be changed.” Is displayed by a balloon.

  Steps ST8 to ST10: Further, referring to the height master file 15, it is determined from the height of the article A, and it is determined whether or not the height restriction of the corresponding place is violated. If the height limit is violated, an alarm is output and a message is output. Also here, for example, along with the output of a beep sound, the shape 34 is blinked, and a message “The height limit is applied. The place needs to be changed.” Is displayed in a balloon.

  In addition, any of the determination processes of conflicts with the lifting weight limit, load resistance limit, and height limit of these storage floors may be first, and the determination order is not limited. Furthermore, in the case of goods storage that allows stacking, especially when judging conflicts with load-bearing restrictions and height restrictions, after judging interference with other articles, the total weight and stacking height at the stage when stacking is executed. This can be done after calculating the length.

  In this way, if the conflict with the lifting weight limit, load bearing limit, and height limit of the storage floor is cleared, the presence or absence of interference with other articles and equipment is determined in terms of time and location. Judging from both sides.

  Step ST11: Referring to the quantity master file 11 and the equipment master file 12, the equipment arranged in the period in which the plan is newly planned, the information of all articles already planned in the period, the period, Get the coordinate data of the place or location. In this case, as shown in FIGS. 16A to 16D, when the start date / time “StartDay” and the planned end date / time “EndDay” of the new placement plan target article A are represented in the corresponding position, (1 ) An article group and a facility group whose scheduled start date and time is before the scheduled start date and time (StartDay) of the article A and whose scheduled end date and time is before the scheduled end date and time (EndDay) of the article A (FIG. 16 (a) -Case1) ), (2) an article group and an equipment group whose scheduled end date and time is later than the scheduled start date and time (EndDay) of the article A at the scheduled start date and time after the scheduled start date and time (StartDay) of the article A (FIG. 16). (B) -Case2), (3) a group of articles whose scheduled start date and time is before the scheduled start date and time (StartDay) of the article A, and whose scheduled end date and time is after the scheduled end date and time (EndDay) of the article A Equipment group (in the case of FIG. 16 (c) -Case3), (4) Article A The article group and facility group (in the case of FIG. 16 (d) -Case4) whose scheduled end date and time is earlier than the scheduled start date and time (EndDay) of the article A and after the scheduled start date and time (StartDay) Information on all articles and equipment corresponding to any of them, the period, coordinate data of the place or location is acquired.

  Step ST12: If there is no article group or equipment group related to the relevant period, the upper left and lower right coordinates (x1, y1) of the place where the shape 34 of the article A is dropped as the place of the article A ; The placement plan for the placement period is registered in the quantity master file 11 together with (x2, y2).

  Steps ST13 and ST14: It is determined whether or not there is an article or equipment arranged at a position overlapping the coordinate position of the article A acquired in the article group and equipment group extracted in step ST11. The determination of the overlap is performed based on whether or not there is an article or facility that interferes in any manner of the 4 × 4 matrix arrangement shown in FIG.

  Here, the calculation time is shortened by simply determining the shape of each shape from a rectangular shape determined from two points of the upper left and lower right coordinates. In FIG. 17, the coordinates of the planning target article A are (x1, y1); (x2, y2), and the coordinates of the search target article are (a1, b1); (a2, b2). For example, the overlapping mode of FIG. 17 (1, I) indicates that the planning target article A is larger, but interferes with the existing article and the left shoulder. The overlapping mode of FIG. 3 (3, IV) shows that the planned object A is smaller and overlaps with the existing article leaving its upper part.

  Step ST15: If there is no article or equipment that overlaps in time, or if the place does not interfere even if there is an article or equipment that overlaps in time, the new article A is allowed to be placed in that place. Then, the placement plan is registered in the quantity master file 11.

  Step ST16: On the other hand, when an article or equipment that overlaps in time and interferes with the place of placement is found, an alarm indicating “overlap” is given, for example, by a beeping sound regarding the arrangement of the article A at the place. The warning is given by blinking the shape 34 of the article A or changing the color to red. It can also be displayed as a balloon message.

  In registration to the storage plan, the quantity master file 11 shown in FIG. 5 is loaded with the article name, number, shape, dimension, etc., the loading date and time (scheduled starting date and time), the unloading date and time (scheduled ending date and time), the upper left and lower right of the storage location. The coordinates of are newly registered.

  The above-described placement plan formulation process is performed by designating the carry-in date and time and the carry-out date and time for all items necessary for product production.

  Depending on the planned date and time, there is an operation of moving a certain article from one place on the floor to another place on a certain date and time. In that case, the corresponding date / time is designated and the location plan screen 31A for that date / time is displayed. Then, by dragging and dropping the corresponding article with the cursor, the start date / time is registered at the corresponding location as long as it does not violate the restrictions on the destination, as in the above processing. In this case, the movement date / time of the article is updated and registered as the scheduled end date / time at the location of the movement source.

[Conflict resolution processing]
The conflict resolution processing by the place plan formulation unit 30 will be described using the flowchart of FIG. When there is interference with other goods or equipment in time and place during the place planning, the conflict will be resolved either by adjusting the date and time of delivery or changing the place after the alarm is output.
