Hereinafter, an example of the operation of the present embodiment will be described.
As illustrated in the production system 300, the cleaning work assignment apparatus 100 according to the present embodiment is disposed in the tank by a method specified before or after manufacturing according to the manufacturing plans of the preparation tank 320 and the upstream tank 310. A plan (CIP) plan (start / end time for each facility, type of CIP) is prepared. Further, the result is displayed on the screen of the output unit 150 as a Gantt chart bar for work as illustrated in FIG.

  In addition, the work (CIP) plan (start / end time for each facility, type of CIP) for cleaning the filling line piping 330 by a method specified before or after manufacturing in accordance with the manufacturing plan of the filling / packaging line 340 And the result is displayed on the screen of the output unit 150 as a Gantt chart bar as illustrated in FIG.

The CIP allocation logic executed by the cleaning operation allocation program 700 in the cleaning operation allocation apparatus 100 of the present embodiment is as follows as an example.
In order to realize this logic, in the cleaning work assignment program 700 of the present embodiment, the details of the CIP specification set based on the CIP code definition table 210 according to the request of the manufacturing process using the manufacturing equipment, that is, the CIP A cleaning work assignment function (cleaning work assignment means) for determining whether the cleaning work defined by the pattern (CIP pattern code 237) is assigned to the pre-process or the post-process of the manufacturing process, and assignment before and after the manufacturing process Based on the required time set in the CIP pattern (CIP code definition table 210), a cleaning work time assignment function (cleaning work time assigning means) for assigning the required time for the cleaning work in the manufacturing process is provided.

(I) CIP allocation position [S01]. As work on main resources (production equipment) such as the upstream tank 310, the mixing tank 320, the filling line piping 330, etc., the work is assigned before or after the production equipment is produced. The pre-production or post-production is designated in advance in the CIP code definition table 210 by switching the production (every switching).

  [S02]. The allocation of sub-resources (CIP facilities) such as CIP control device 350, CIP recovery tank 360, CIP recovery tank 370, etc., is aligned with the CIP in the production facility (line, tank) as the main resource. Assign.

(II). CIP allocation method [S03]. The CIP assignment in the cleaning work assignment program 700 has two assignment methods: automatic assignment and manual assignment by user intervention. Whether to perform manual allocation or automatic allocation is specified in advance in the CIP code definition table 210 by switching the production (every switching).

[S04]. By default, manual assignment is preferentially selected.
(III). Automatic assignment of CIP In the CIP code definition table 210 described in [S03] above, when the automatic execution identifier 214 is defined to be designated as automatic assignment, before or after production when switching occurs ( This automatically assigns the CIP with the pre-production / post-production identifier 213) of the CIP code definition table 210.

Even if the product is not switched, there is a case where CIP must be performed so as not to exceed a certain time in order to prevent gonococci and the like from propagating on specific equipment used for a long period of time.
In the case of this embodiment, this fixed time interval is defined in advance by the CIP non-implementation allowable time 233 of the equipment master table 230 for each equipment. The cleaning work assignment program 700 checks the non-execution period for each equipment at the time of assignment, and if the allowable time defined by the CIP non-execution allowable time 233 is exceeded, the CIP is forced to be used before using the equipment. As implemented, the CIP indicated by CIP code 234 is allocated.

  As used herein, “when the allowable time defined by the CIP non-implementation allowable time 233 is exceeded” means that the time from the previous CIP completion time to the completion of the work at the equipment using the equipment is CIP This refers to the case where the allowable time defined by the non-executable allowable time 233 is exceeded, and it is checked whether or not the time exceeds the CIP non-executable allowable time 233.

  Because it is not possible to insert a CIP in the middle once the equipment is used, it is necessary to check whether the period until the work of the equipment exceeds the allowable time defined by the CIP non-permitted allowable time 233 Because there is.

  Therefore, when the CIP is executed before production, the cleaning work assignment program 700, when the period from the previous CIP completion time to the end of the work of the facility next exceeds the CIP non-permitted allowable time, even if the above [S03 ], The CIP is forcibly assigned before the production of the work.

The cleaning work assignment program 700 does not consider the allowable interval time when the set value of the CIP non-permitted allowable time 233 is “0” or blank and the blending operation comes within.
When the CIP is designated to be executed after production, the CIP is automatically assigned after the tank is produced. However, it may be necessary to adjust the execution timing. In this case, the method of adjusting the execution timing in the cleaning work assignment program 700 performs “exception adjustment of CIP execution timing” to be described later.

(IV). Manual assignment of CIP Manual assignment of CIP is a plan dialog correction screen (cleaning work assignment operation screen 151) provided by the cleaning work assignment program 700. Before the setup work of the operation designated by the mouse operation by the planner, Alternatively, it is performed by assigning a CIP operation (cleaning operation 440) after the post-setup operation.

(V). CIP pattern, pre-production execution / post-production execution, CIP station number, automatic assignment / manual assignment, and CIP occupation time acquisition / designation method CIP patterns are defined in advance in the CIP code definition table 210 for each switching. The cleaning work assignment program 700 obtains necessary data by referring to the pattern information (CIP name 212 to CIP time 216) defined in the equipment master table 230 at the time of assignment and designates it for assignment.

  The cleaning work assignment program 700 acquires the CIP code 211 set in the CIP code 234 of the equipment master table 230 as the CIP pattern used for the forced assignment of the CIP by the CIP non-permitted time check, and designates it for assignment. .

  In the case of CIP assignment by checking the CIP non-permitted time, it is necessary to specify a CIP station number. The CIP station number is defined in the CIP station number 235 of the equipment master table 230 for each equipment, and the data of the CIP station number 235 is acquired with reference to the equipment master table 230 and designated for allocation.

However, the cleaning work assignment program 700 sets the assignment position of the cleaning work 440 so that the same CIP station number is not executed at the same time.
The cleaning work assignment program 700 refers to the CIP pattern information (pre-production / post-production identifier 213) defined in the CIP code definition table 210 to determine whether the CIP is assigned to pre-production / post-production execution. Used for assignment.

In the automatic assignment / manual assignment of CIP, the CIP pattern information defined in the CIP code definition table 210 is obtained by encoding in advance every time switching is performed by the master, and designated for assignment.
The CIP time varies depending on the CIP specification (switching specification, production item specification), and the cleaning work assignment program 700 is a value of the applicable time segment 215 (CIP time 216) defined in the CIP code definition table 210 for each CIP code. Is used.

(VI). Exception adjustment of CIP execution timing The cleaning work assignment program 700, when assigning a CIP operation (cleaning work 440) before the production of the upstream tank 310, when the cleaning work 440 overlaps with a rotation, failure, or holiday operation. Assigns CIP operations before rest, failure and holiday operations.

After the assignment of the CIP operation (cleaning work 440), the cleaning work assignment program 700 performs a process of shifting the CIP start time according to the following conditions J1 and J2.
(J1). When the time of CIP operation with the same CIP station number overlaps, the start time of CIP operation with late start time is shifted.

(J2). If the start times of the CIP operations to be compared are the same, the operation start time of the downstream process is shifted (upstream process priority).
FIG. 9, FIG. 10, FIG. 11, FIG. 12, and FIG. 13 below illustrate an example of the allocation process of the cleaning operation 440 by the above-described cleaning operation allocation program 700.

  As illustrated in FIG. 9, the cleaning work assignment program 700, when no other work is assigned within the CIP non-permitted allowable time T0 (CIP non-permitted time 233), CIP (cleaning work 440) is Assign according to the free time.

  As illustrated in FIG. 10, the cleaning work assignment program 700, when another work is assigned within the CIP non-permitted time T0 (CIP non-permitted time 233), the CIP is assigned before that work. Assign.

  As illustrated in FIG. 11, the cleaning work allocation program 700 is a specification that does not ignore the non-working time zone 450 when allocating CIP (cleaning work 440) before production in the mixing tank 320 or the upstream tank 310. In some cases, when there is an overlap with a break, failure, or holiday, a CIP (cleaning operation 440) is assigned before the break, failure, or holiday.

  In the present embodiment, for example, the cleaning work assignment program 700 assigns CIPs for each lot (order) for CIP (manufacturing plan 400) after production of the upstream tank 310.

  That is, as illustrated in FIG. 12, when CIP is designated after production (after post-setup 430), there is a case where time is left between batches for the convenience of manufacturing (for example, alternate operation). in the case of). In this case, when assigning CIPs after the post-setup 430, the cleaning work assignment program 700 does not assign CIPs individually after completion of individual batches, but assigns CIPs after completion of lots (orders).

  That is, instead of setting a cleaning operation 440 after each manufacturing operation 420 that is repeated multiple times between the pre-setup 410 and the post-setup 430, the cleaning is performed only once after the post-setup 430 of the last manufacturing operation 420. Work 440 is assigned.

  As illustrated in FIG. 13, the cleaning work assignment program 700 has the same CIP station number CIP (cleaning work 440) execution period when the CIP is assigned (that is, the use of the CIP control device 350 competes). ), The start time of the CIP with a late start time is shifted backward by ΔT by the completion time of the CIP with a early start time.

  In addition, when the execution period of the CIP (cleaning operation 440) with the same CIP station number overlaps between the upstream and downstream of the manufacturing process, the cleaning operation allocation program 700 sets the CIP start time of the downstream process. Shift sequentially. In other words, the cleaning operation 440 is assigned so as to give priority to the execution of the CIP in the upstream process.

Next, the operation of the cleaning work assignment program 700 when “manual assignment” is set in the automatic execution identifier 214 of the CIP code definition table 210 will be described.
In this case, the cleaning work assignment program 700 displays a cleaning work assignment operation screen 151 illustrated in FIG. 14 on the output unit 150 as a user interface, and supports manual assignment of the cleaning work 440 by the user.

On the cleaning work assignment operation screen 151, a Gantt chart display unit 152 is provided, and a Gantt chart showing the manufacturing plan 400 illustrated in FIG. 5 is displayed.
The outline of the manual assignment field support function by the cleaning work assignment program 700 is as follows as an example.

  [S11]. In manual CIP assignment, a planner (user) designates (selects) a work (manufacturing plan 400) on the Gantt chart display unit 152 with a mouse, and CIP (cleaning) is performed on the setup 410 or the back setup 430 of the work. Insert operation 440).

  [S12]. After specifying the work, the pop-up menu 153 is displayed with the mouse, and when the insertion is performed using the displayed “insert CIP work” or “delete CIP work” (when “insert CIP work” is selected), the CIP Can be selected before or after production.

  [S13]. When deleting a CIP work (cleaning work 440), a CIP work to be deleted is designated (selected), a pop-up menu 153 is displayed with the mouse, and "Delete CIP work" is selected, and the corresponding CIP work is deleted. .

  [S14] The CIP pattern, CIP station number, and CIP occupation time are acquired by referring to the CIP code definition table 210 in the same manner as in the automatic allocation (V) described above.

  [S15]. Based on the assignment of the CIP of the previous setup 410 specified in [S12] or the CIP after the subsequent setup 430, the setup of the specified work (manufacturing plan 400) on the Gantt chart of the Gantt chart display unit 152 is performed. A Gantt bar for the cleaning operation 440 is added before 410 or after the post-setup 430 with the CIP occupation time (CIP time 216 specified by the application time segment 215) acquired in [S14] described above as a width.

  [S16]. In the above [S15], when a CIP gantry bar (cleaning operation 440) is added before the pre-setting 410 of the designated operation (manufacturing plan 400), the CIP (cleaning operation) is 1 second before the start time of the pre-setting 410. 440) as the end time, and the CIP start time is determined retroactively by the CIP occupation time.

  In this case, as illustrated on the right side of FIG. 15, when there is not enough free space TS used for CIP (cleaning operation 440) before the pre-setting 410, the cleaning operation allocation program 700 reads “Space allocated to CIP. "There is not enough, please open the space and try again." An error message is output and the assignment is not executed.

In the case of a specification that ignores the non-working time zone 450, the cleaning work 440 is fitted and assigned in the time zone of the non-working time zone 450.
[S17]. In the above [S15], when a CIP gantry bar is added after the post-setup 430 of the designated operation (production plan 400), 1 second after the end time of the post-setup 430 is set as the start time of the CIP (cleaning operation 440). The CIP end time is determined by extending backward by the CIP occupation time (CIP time 216).

  In this case, as shown in the upper right of FIG. 15, if there is not enough free space TS to be used for CIP after post-setup 430, “There is not enough space to allocate to CIP. Message is output and the assignment is not executed.

[S18]. After the CIP is assigned to the facility side, the assignment of the CIP control device 350 is assigned in accordance with the CIP of the facility side at the same time (see the lower part of FIG. 5 above).
[S19]. When CIPs with the same CIP station number are executed in a time-overlapping manner, an error message “Please adjust because the same CIP station number overlaps” is output, and the assignment is not executed.

An example of the operation of the cleaning work assignment program 700 in the cleaning work assignment apparatus 100 of the present embodiment as described above will be described with reference to the flowcharts of FIGS. 16 and 17.
16 shows an example of a processing flow in the case of automatic allocation, and FIG. 17 shows an example of a processing flow in the case of manual allocation.

  As illustrated in FIG. 16, the cleaning work assignment program 700 installed in the cleaning work assignment apparatus 100 inputs the work plan data 800, reads out the manufacturing plan 400 to which the CIP should be assigned, and performs the cleaning work assignment operation. The information is displayed on the Gantt chart display unit 152 of the screen 151.

  Then, the equipment master table 230 is accessed based on the equipment code 231 of the equipment used in the manufacturing plan 400 to obtain the CIP code 234, and the CIP code definition table 210 is searched using the CIP code 234 as a key. A CIP pattern (CIP code 211 to CIP time 216) is acquired (step 502).

  Thereafter, the automatic execution identifier 214 of the CIP pattern is referred to determine whether automatic assignment or manual assignment is made (step 504). In the case of manual allocation, a manual allocation process 600 exemplified in the flowchart of FIG. 17 described later is executed (step 520).

  On the other hand, if it is determined in step 504 that automatic allocation is performed, the allocation position of the cleaning operation 440 in the manufacturing plan 400 is provisionally determined by the method described above (step 506).

Further, the CIP time 216 is determined based on the application time segment 215 of the CIP pattern acquired as described above (step 508).
After that, when the CIP non-permitted allowable time 233 of the equipment master table 230 corresponding to the facility is 0 or not empty, the value of the CIP non-permitted allowable time 233 is set as the CIP non-permitted allowable time T0, It is determined whether or not forced execution of CIP is required at regular intervals less than time 233 (step 510).

  If it is determined that it is necessary, for example, by the method illustrated in FIGS. 9, 10, 11, etc., the manufacturing plan 400 is set so that the CIP execution interval does not exceed the CIP non-permitted time T 0. The assignment of CIP (cleaning operation 440) to is executed (step 512).

  Furthermore, it is determined whether or not the allocation position of the cleaning operation 440 overlaps with the non-working time zone 450 of the cleaning operation 440, that is, whether or not exception adjustment of the execution timing of CIP is necessary (step 514). As illustrated in FIG. 11, the cleaning operation 440 is assigned to the front side of the non-operation time zone 450 (step 516).

The manufacturing plan 400 including the cleaning operation 440 thus obtained is output as CIP operation plan data 900 (step 518).
In the above-described manual allocation processing 600, as illustrated in FIG. 17, when the selection of the production plan 400 in the Gantt chart display unit 152 is detected (step 602), a pop-up menu 153 is displayed (step 604).

  Then, it is determined whether or not CIP insertion is selected (step 606). If it is not insertion (that is, deletion), the Gantt bar of the cleaning operation 440 designated by the user is detected from the Gantt chart display unit 152. Delete (step 636) and return to step 602.

  On the other hand, if CIP insertion is selected in step 606, the pre-production CIP / post-production CIP selection menu 154 is displayed (step 608), and the CIP code 234 relating to the equipment included in the selected manufacturing plan 400 is displayed. Then, from the equipment master table 230, based on the CIP code 234, the CIP code definition table 210 is searched to obtain the CIP pattern (CIP code 211 to CIP time 216) of the corresponding CIP code 211 (step 610). .

  Then, it is determined whether or not an instruction to insert the previous setup 410 has been instructed (step 612). If the previous setup 410 is inserted before, the CIP start time is retroactively determined (step 614). It is determined whether or not there is a space (step 616).

If there is no insertion space, an error message is displayed and the process returns to step 602 (step 626).
If insertion after the cleaning operation 440 is selected in step 612 described above, the CIP end time is set as the application time segment 215 (CIP time 216) in order to insert the CIP after the post-setup 430. ) Is deferred backward by the occupation time specified in step 630 (step 630).

  Then, it is determined whether or not there is an insertion space for the cleaning operation 440 (step 632). If there is no insertion space, an error message is displayed (step 634), and the process returns to step 602.

  If it is determined in step 616 or step 632 that there is an insertion space, first, a CIP (cleaning operation 440) is assigned to a manufacturing facility such as the upstream tank 310 included in the manufacturing plan 400 (step 618). ).

  Further, the assignment of the station number of the CIP control device 350 is executed (step 620), and it is determined whether or not the station number is duplicated, that is, there is a competition for use of the CIP control device 350 (step 622).

If the station number is duplicated, an error message is displayed (step 628), and the process returns to step 602.
If the station number does not overlap, the assignment of the CIP (cleaning operation 440) to the production plan 400 is confirmed (step 624).

Next, an example of CIP allocation in consideration of receiving and paying CIP after production in equipment such as a mixing tank will be shown.
In the mixing tank, a plurality of tanks of the same type (mixing tank) are connected by the receiving pipeline and the paying pipeline, and the tank to be used is switched by opening and closing the valve, thereby realizing an alternate operation.

  That is, as shown in FIG. 18, a plurality of blending tanks 320A and blending tanks 320B are placed between the receiving pipe line 313A and the paying pipe line 330A via the receiving valve 312A, the receiving valve 312B, the paying valve 331A, and the paying valve 331B. In the case of the configuration connected in common, alternating operation can be realized by operating the receiving valve 312A, the receiving valve 312B, the paying valve 331A, and the paying valve 331B.

  In such an equipment configuration, when producing a plurality of batches by alternately operating a plurality of blending tanks 320A and blending tanks 320B, in the tank where the payment has been completed, the payout pipeline 330A is still being used in the other tank. Since there is a case, the payment CIP using the spray ball 373 and the payment pipeline 330A cannot be performed.

  However, it is desirable to carry out CIP as early as possible for the tanks that have already been paid off. For this reason, for example, only in the mixing tank, the CIP is divided into the receiving CIP and the paying CIP, and the CIP after production of the mixing tank is performed by the logic illustrated in FIGS. 19 and 20 below.

  The receiving CIP is to perform CIP inside the receiving pipeline 313A and the mixing tank 320A (the mixing tank 320B) by introducing the cleaning liquid into the mixing tank 320A or the mixing tank 320B via the receiving pipeline 313A.

  The pay CIP is to clean the inside of the mix tank 320A and the mix tank 320B by using the spray balls 373 provided in each of the mix tank 320A and the mix tank 320B and the pay pipeline 330A.

  That is, as illustrated in FIG. 19, when manufacturing in multiple batches in a blending tank, the CIP assigned to the person who finishes paying first is CIP 440A, and the CIP assigned to the person who finishes paying later is paid. CIP440B.

On the other hand, when manufacturing with 1 batch with the mixing tank 320A and the mixing tank 320B, as shown in FIG. 20, CIP operation is allocated also to the mixing tank 320B which is not operating.
In this case, the receiving CIP 440A is assigned as the tank where the payment is finished first for the blend tank 320B which is not used, and the pay CIP 440B is assigned as the tank where the payment is finished later, for the preparation tank 320A which is actually manufactured.

Also in this case, similarly to the above, the CIP assigned to the person who finishes paying first becomes the receiving CIP 440A, and the CIP assigned to the person who finishes paying later becomes the paying CIP 440B.
In the case of manufacturing in 0 batch with the blending tank 320A and the blending tank 320B, the two are grouped and the blending tanks of the same group are targeted.

  In this case, the pattern codes of the receiving CIP 440A and the paying CIP 440B of the mixing tank 320A and the mixing tank 320B are determined based on the receiving CIP pattern code 236 and the CIP pattern code 237 defined in the equipment master table 230 described above.

  As described above, according to the present embodiment, in the planning of the cleaning operation in the production system, a method specified before or after manufacturing according to the manufacturing plan 400 of the upstream tank 310, the mixing tank 320, and the like. The tank cleaning work (CIP) plan (start / end time for each equipment, CIP type) can be planned accurately and efficiently, and the result can be visualized and displayed on the work Gantt chart bar. .

  In addition, the filling line piping 330 of the filling / packaging line 340 is washed by a specified method before or after production in accordance with the production plan (manufacturing plan 400) of the filling (filler) line such as the filling / packaging line 340. A work (CIP) plan (start / end time for each facility, type of CIP) can be planned accurately and efficiently, and the result can be visualized and displayed on the Gantt chart bar of the work.

  As a result, according to the production system in the production system, depending on the target upstream tank 310, blending tank 320, filling line piping 330, filling / packaging line 340, etc., production equipment, production environment conditions, production items, production method, etc. Therefore, it is possible to accurately and efficiently realize the planning of complex CIP operations that need to take into account various factors.
