Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a device used to determine a production plan for a weaving process among textile production plans, and which automatically creates a loom arrangement plan. related to a device for

[Prior Art] Textiles are produced through a spinning process, a yarn processing process, a weaving process, and a finishing process in sequence. Among these, a large number of various types of looms are usually installed for the weaving process. Of these looms,
The creation of a plan regarding which loom to allocate to weaving a certain textile, i.e. the "composition", is particularly important in textile production planning, as the quality of the plan will directly affect the delivery date of the textile and the operating rate of the loom. be.

Now, looms are classified into tapepet looms, dobby looms, etc. depending on the weft shedding device, but looms that have a weft changing device for patterning etc.
Some types differ in the number of types of thread that can be passed through the opening, or ``hole.'' Furthermore, high-speed looms have limitations on the strength of the yarn that can be used.
Therefore, depending on the texture of the fabric and the yarn used,
There are looms that can weave such textiles and others that cannot.

Conventionally, a loom arrangement plan for the looms was created manually by searching for a loom capable of weaving the woven fabric, taking into consideration the delivery date of the woven fabric and the planned production volume.

[Problems to be Solved by the Invention] The following problems arose in the creation of the conventional arrangement plan as described above.

In other words, even if it is possible to specify the loom that should weave a certain textile, when to start weaving on this loom, the expected arrival date of the yarn and the load on the loom must be considered. ,
Unable to create a platform layout plan.

Therefore, those who prepare the stand arrangement plan have endeavored to make the plan by taking into account the scheduled arrival date of the yarn. However, as the number of fabrics that need to be arranged on a stand has increased due to the trend toward small-lot production of a wide variety of products, it is difficult to consider the scheduled arrival date of all raw yarns for all fabrics. It was becoming virtually impossible to create a plan because it required an enormous amount of time and effort. In the case of woolen fabrics, weaving cannot begin unless all the yarn necessary for patterning is received.
This was a particular problem.

Furthermore, those who prepare the loom layout plan take the load on the loom into consideration when making the plan. However, even if you create a loom layout plan taking into account the load on the loom at a certain point, after that point,
Weaving work may be delayed due to problems with the loom. At this time, for the fabric that is placed on the loom and was scheduled to be weaved after the fabric currently being woven is finished, the raw yarn that arrived late due to the weaving start time is delayed. Along with this, there were times when weaving could not be completed in time for delivery. On the other hand, regarding a certain loom,
Even if the weaving work is completed quickly, weaving cannot be started until the yarn for the next fabric to be woven arrives, which poses a problem in that the operating rate of the loom decreases.

In other words, with conventional loom layout plans created manually, proceeding with the weaving process according to this plan would lead to an increase in the amount of yarn in progress and a decrease in the loom operating rate. There was something that caused it.

Therefore, when actually weaving, it is often necessary to change the table arrangement, making it difficult to carry out the weaving process in a planned manner. In addition, in order to meet the deadline, it becomes necessary to change the loom arrangement of a loom that has already started weaving, and when such a loom arrangement change is made, if the structure of the fabric to be woven is different, it is necessary to adjust the loom. Replacement work will be required. In particular, when the number of warp threads is different, it is necessary to change the healds and rethread the warp threads through the healds, that is, a "pulling work" is required. Therefore, when such a change in the table arrangement is made, time and labor for these operations are wasted, and efficient weaving operations may not be carried out.

Therefore, a device has been proposed that automatically creates a loom arrangement plan, but information about the actual yarn processing progress and weaving results is fed back to the loom arrangement plan created by this device. As a result, it ended up being a desk plan similar to conventional manual formulation plans, which lacked practicality.

In view of the above points, the present invention uses a computer to fully consider not only the delivery date of the textile, the planned production volume, and the functions of the weavable fibers, but also the scheduled arrival date of the yarn and the load on the loom. It is an object of the present invention to provide a device that automatically creates an optimal loom arrangement plan according to the actual situation.

[Means for solving the problems] The structure of the automatic loom arrangement plan creation device of the present invention is as follows.
This will be explained based on FIG.

Using the above information, the machine number determining means 106:
With reference to the delivery date of the textile, machine numbers of the types of looms corresponding to the number of looms arranged are determined. Further, the scheduled weaving start date determining means 107 determines the latest date when yarn can be introduced or the latest date when weaving can be started.

Hereinafter, one embodiment of the present invention will be described in more detail based on the drawings.

Figure 2 shows an outline of the device of this embodiment, where 1 is an input device such as a keyboard, 2 is an input device such as a keyboard, and 2 is an input device such as a keyboard.
Display devices such as CRT displays and printers, 3
is a microcomputer consisting of a CPU (central processing unit), ROM (read-only memory), RAM (random access memory), I/O port, etc.; 4 is an auxiliary storage device such as a magnetic disk or magnetic tape; 5 is an auxiliary storage device such as a magnetic disk or magnetic tape; is a loom, and each device 1, 2, 4
And the loom 5 is connected to the microcomputer 3 via an I/O port.

The input device 1 corresponds to the machine arrangement information input means 103, and inputs information such as the date of preparation of the machine arrangement plan and the amount of yarn actually loaded on one warp beam of each loom to the microcomputer 3. used for input.

The display device 2 is used to display intermediate results obtained by the microcomputer 3 and the final arrangement plan.

In the auxiliary storage device 4, a loom file 4a, a textile file 4b, and a stand file 4c are registered.

The loom file 4a stores the loom information storage means 1.
01, which corresponds to the loom machine number M
For each (=1 to Y), model S (M), rotation speed R (S
(M)) and the planned amount of yarn to be loaded onto one warp beam V(S(M)) are stored.

The textile file 4b is the textile information storage means 1.
02 and the yarn information storage means 103, and for each textile contract A (=1 to X),
The delivery date T(A) of this fabric, the weft density U(A), the model C(A) of the loom that can be installed on this fabric, and the pattern P(A) of the fabric included in this fabric ( =1~
X′) is memorized. Also, the pattern of this fabric is P.
For each (A), the production amount Q (P(A)) of this woven fabric, the weaving situation variable J (P(A)) (=0, 1, 2), and the type G of the raw yarn necessary for manufacturing this woven fabric. (P(A)) (=1~X″)

Furthermore, for each raw yarn G (P(A)), the date or scheduled input date D3 (G(P(A))) of the fabric yarn to the first processing process in the processing process series of this raw yarn and The standard processing days or actual processing days L(G(P(A))) for each process included in this yarn processing process series is stored.

In woven fabrics with the same contract, the woven structure is the same even if the pattern is different, so the weft density U(A) and the type of loom C(A) that can be mixed with this woven fabric is stored for each contract A. The values of the weaving status variable J(P(A)) are classified and stored as follows for the fabric of pattern P(A). That is, for example, if weaving has not started, the value is 0.

As long as the processing of a process is not completed, the standard number of processing days for that process is stored, and this is updated to the number of days actually required for processing each time the processing of that process is completed.

The configuration file 4c is the microcomputer 3
This is used to store the final platform arrangement plan obtained by

In addition to conventional looms, the loom 5 has means for outputting the cumulative operating time of the loom by detecting whether or not the spindle is rotating and accumulating the actual operating time.

The ROM of the microcomputer 3 mainly stores the following programs, and is used as a device arrangement planning means 104. In other words, a program is created that predicts the latest date on which raw yarn necessary for fabric production can be input into the weaving process, that is, the latest date when yarn can be input, and the type of loom to be installed is selected. , a program that calculates the number of beams to be arranged and the number of beams to be allocated for warp threads and prepares for the arrangement of the beams;
A program that determines the scheduled amount of raw yarn to be loaded onto one warp beam and calculates the number of days required to weave the fabric, and a program that calculates the number of days required to weave the fabric, and the program that completes the weaving of the currently operating loom and starts weaving the next fabric. a program for predicting the date when weaving will be possible, that is, the date when weaving can be started; the latest date when the yarn can be input; the type of the loom; the number of looms and the number of beams; and the loading of the yarn onto the beams. This is a program that creates a weaving plan using the planned amount, the number of days required for weaving, and the possible start date of weaving. However, these programs do not need to be stored in ROM;
The program may be stored in the auxiliary storage device 4, loaded into the RAM, and then executed.

Next, the processing performed by the microcomputer 3 will be explained in detail using the flowcharts shown in FIGS. 3 to 8.

First, the main routine shown in FIG. 3 will be explained.

In step 1, all patterns P(A) (=1 to X) of all contracts A (=1 to X) are entered using the input device 1.
For the fabric X′), the value of the weaving status variable J(P(A)) of the fabric file 4b is set. However, if the settings have already been made, it is only necessary to reset the settings for the fabric that needs to be changed.

In step 2, call the subroutine and
For a fabric whose weaving status variable J(P(A)) has a value of 0, the latest date when yarn can be inputted is predicted for that fabric.

In step 3, the subroutine is similarly called to select the type of loom to be installed for the fabric whose weaving status variable J(P(A)) has a value of 0, and to determine the number of looms to be installed and the number of beams to be allocated for the warp. Calculate and prepare for placement.

In step 4, the subroutine is called in the same way to adjust the number of weaving machines and the number of beams allocated for warp yarns calculated in step 3 for the fabric whose value of the weaving status variable J(P(A)) is 0. Input device 1
After performing this using the display device 2, the planned amount of yarn to be loaded onto one warp beam is determined, and
Calculate the number of days required to weave the fabric.

In step 5, call the subroutine and
For all looms with machine numbers M (=1 to Y),
The weaving start date is predicted.

In step 6, call the subroutine and
Regarding the fabric for which the value of the weaving status variable J(P(A)) is 0, the latest date when yarn can be introduced predicted in step 2 and the type of loom set in step 3 are determined similarly. The number of machines and the number of warp beams to be allocated calculated in step 3 and adjusted in step 4, the planned amount of raw yarn to be loaded on one warp beam determined in step 4, and the amount of yarn to be loaded on one warp beam determined in step 4.
The number of days required for weaving the fabric calculated in Step 5
A weaving table arrangement plan is created using the predicted weaving start date.

In step 7, the process executed when it is determined in step 6 that the table cannot be arranged is executed, and the process returns to step 1 again.

Next, each subroutine will be explained in detail.

FIG. 4 shows a subroutine for predicting the latest date when yarn can be introduced, which executes processing using the textile file 4b.

In step 11 and step 12, the fabric contract A
and its pattern P(A) are each initialized to 1. In step 13, it is checked whether the value of the weaving situation variable J(P(A)) is 0 or not, and if it is not 0, the step
Jump to step 21 without executing the processes from step 14 to step 20. When J(P(A))=0, weaving has not yet started, so the process advances to step 14.

In step 14, G(P(A)) is set to 1 for the raw yarn G(P(A)) (=1~X'') necessary for manufacturing the woven fabric P(A) for subsequent processing. Initialize.In step 15, the series of processing steps for the raw yarn G (P(A)) is input from the textile file 4b.In step 16, the first processing step in this series of yarn processing steps is input. The input date or scheduled input date D3 (G (P (A))) of the fabric yarn is ascertained in Step 17. Using the standard processing days or actual processing days L(G(P(A))) for each process, the processing completion date D4(G(P(A))) of the final yarn processing step is calculated. In step 18, G(P(A)) is incremented to check the next yarn, and in step 19
Check whether this is greater than X''. If it is not, there is still yarn left to calculate D4 (G (P(A))), so return to step 15. If it is greater than X'', proceed to step 20. Proceed to D4(G(P(A)))
The latest day among (G(P(A))=1 to X'') is set as the latest yarn input possible date D1(P((A)).

In step 21, P(A) is incremented to check for the next pattern of fabric, and in step 22 it is checked whether it is larger than X', and if it is not, the process returns to step 13. Next, in step 23, A is incremented to check the next contract fabric, and in step 24 it is checked whether this is greater than X. If not, the process returns to step 13. A
When is larger than X, the process of this subroutine is ended and the process returns to the main routine.

FIG. 5 shows the table arrangement reference subroutine.

In steps 31 and 32, the fabric contract A
and its pattern P(A) are each initialized to 1. In step 33, it is checked whether the value of the weaving situation variable J (P(A)) is 0 or not, and if it is not 0, the step
The process jumps to step 39 without executing the processes from step 34 to step 38. When J(P(A))=0, weaving has not yet started, so the process advances to step 34.

In step 34, in order to execute the processing of steps 35 and 36 only once for one contract A, it is checked whether the pattern P(A) of the fabric is 1 or not. That is, when P(A) is not 1, the process jumps to step 37, but when it is 1, the processes of step 35 and step 36 are executed. In step 35, for the fabric of contract A, the loom type S(A) to be arranged is selected from among the loom types C(A) that can be combined obtained from the fabric file 4b. Even if the patterns are different among the fabrics of one contract, the fabric structure is the same, so for the fabrics of the same contract A, the same model S(A) is selected. When making this selection,
Select trains in descending order of rank. Therefore, by giving a high priority to high-speed looms, high-speed looms can be selected preferentially. moreover,
In step 36, for the selected loom type S(A), the loom file 4a is used to determine the rotation speed R(S(A)) of the loom and the raw yarn to one warp beam of the loom. Input the planned loading amount V(S(A)).

In step 37, for the fabric of pattern P(A), the arrangement of the loom of the model S(A) selected for the fabric of pattern P(A) is determined in step 35. Calculate the number NA (P(A)) using the following formula (1).

NA(P(A)) = [((U(A)*Q(P(A)) *60*24)/R(S(A))/(T(A)-D1(P(A)) )+1] ...(1) Here, U(A), T(A) and Q(P(A)) are the weft density, the delivery date of the woven fabric, and the manufacturing of the woven fabric with pattern P(A), respectively. amount of the textile file 4.
This is input from b. The delivery date T(A) is expressed in days, and the unit of R(S(A)) is rpm. Note that the symbols * and / represent multiplication and division, respectively, and the symbol [z] is a Gaussian symbol representing the largest integer not exceeding z. (The same applies hereinafter.) In step 38, the number of warp beams NC (P(A)) to be assigned to the loom of model S(A) is calculated using the following equation (2).

NC(P(A))=[Q(P(A))/V(S(A))+1]...(2) Note that V(S(A)) is input from the loom file 4a. , is the planned amount of yarn to be loaded onto one warp beam of a loom of model S(A).

In step 39, P(A) is incremented to examine the next pattern of fabric, and in step 40 it is checked whether this is greater than X'. If not, the process returns to step 33. Next, in step 41,
A is incremented to check for the next contract fabric, and step 42 checks whether it is greater than X. If not, the process returns to step 32.
When A is greater than X, the process of this subroutine is ended and the process returns to the main routine.

FIG. 6 shows a subroutine for adjusting the number of devices and the number of beams.

In steps 51 and 52, the fabric contract A
and its pattern P(A) are each initialized to 1. In step 53, it is checked whether the value of the weaving situation variable J(P(A)) is 0 or not, and if it is not 0, the step
The process jumps to step 59 without executing the processes from step 54 to step 58. When J(P(A))=0, weaving has not yet started, so the process advances to step 54.

In step 54, the NA (P(A)) and NC (P(A)) obtained in the table arrangement preparation subroutine, that is, the model S(A) selected for the fabric with the pattern P(A)
Regarding the number of looms arranged and the number of warp beams assigned to this loom, it is checked whether the former is larger than the latter. When NA(P(A))>NC(P(A)), a problem arises in that some functions cannot be equipped with beams. Therefore, in this case, in step 55, these are displayed on the display device 2 to encourage the planner's instructions, and in step 56, any of them is changed and inputted using the input device 1.
Make sure that NA(P(A))≦NC(P(A)). Note that the display items in step 55 are contract A, pattern P(A), NA (P(A)), and NC (P(A)). In addition, as decision materials for planners, the production volume (P(A)) of fabrics with pattern P(A), the delivery date T(A) of fabrics with contract A,
The latest date D1 (P(A)) when raw yarn necessary for manufacturing the fabric of pattern P(A) can be input, the model S(A) of the loom selected for the fabric of contract A, and the model S(A) ) of the loom rotation speed R(S
(A)), the planned amount of yarn to be loaded onto one warp beam of the loom of type S(A), V(S(A)), etc. may be displayed.
If NA(P(A))≦NC(P(A)) in step 54, the process jumps to step 57 without executing steps 55 and 56.

In step 57, the amount of raw yarn to be loaded onto one warp beam of the loom of model S(A) selected for the fabric of pattern P(A), V(S(A)), is calculated using the following formula (3). ) to be corrected.

V(S(A))=Q(P(A))/NC(P(A))...(3) In step 58, the fabric of pattern P(A) on the selected loom of model S(A) is The number of days D2 (P(A)) required for weaving is calculated using the following formula (4).

D2(P(A)) =V(S(A))*U(A)/R(S(A))...(4) In step 59, P(A) is used to investigate the next pattern of fabric. is incremented, and in step 60 it is checked whether this is greater than X'. If not, the process returns to step 53. Next, in step 61,
A is incremented to check for the next contract fabric, and in step 62 it is checked whether it is greater than X, and if not, the process returns to step 52. A
When is larger than X, the process of this subroutine is ended and the process returns to the main routine.

FIG. 7 shows a subroutine for predicting possible weaving start date.

In this subroutine, all machine numbers M
The possible weaving start date is predicted for the looms (=1 to Y), but the fabric of pattern P(A) currently being woven has already been placed on the loom with machine number M, and this Since the contents have already been stored in the table arrangement file 4c, the correspondence relationship between P(A) and M is input.
(M)).

In step 71, the machine number M of the loom is initialized to 1. In step 72, weaving situation variable J(P(A
Search for a fabric with a pattern P(A(M)) in which the value of (M))) is 1. If this is not present, it is known that the loom with machine number M is not in operation and weaving can be started immediately, so proceed from step 73 to step 74 and determine the expected date DX(P(A(M))) when weaving can be started. After setting the date F, which is the date of creation of the stand arrangement plan, the process jumps to step 78. If there is a corresponding fabric, the process advances from step 73 to step 75.

In step 75, the amount of raw yarn actually loaded on one warp beam of the loom for the fabric of pattern P(A(M)) currently being woven on the loom with machine number M is calculated. (A(M))) is input using the input device 1. In step 76, the above pattern P(A(M))
The cumulative value of the time that the loom with machine number M has already been operating for the fabric of
(M))) is input from the loom 5. Based on this,
In step 77, the possible weaving start date DX(P(A(M))) for the loom with machine number M is predicted using the following equation (5).

DX(P(A(M)))=F +V′(P(A(M)))*U(P(A(M))) /R(S(A(M)))−E(P( A(M)))...
(5) In step 78, M is incremented to check the loom with the next machine number, and step 79
Then it is checked whether this is greater than Y or not, and if it is not, the process returns to step 72. If M is greater than Y, the process of this subroutine is ended and the process returns to the main routine.

FIG. 8 shows the automatic table arrangement subroutine.

In steps 81 and 82, the fabric contract A
and its pattern P(A) are each initialized to 1. In step 83, it is checked whether the value of the weaving situation variable J(P(A))) is 0 or not, and if it is not 0, the step
Jump to step 97 without executing the processing from step 84 to step 96. When J(P(A))=0, since weaving has not yet started, it is necessary to create a table arrangement plan, and the process proceeds to step 84.

In step 84, the number NA (P(A)) of beams adjusted in the number of beams/number of beams adjustment subroutine is calculated.
Assign to variable H. This is because this H is used to control the number of loop executions of the program.

In step 85, the machine number M is entered in the loom information.
With reference to the model S(M) of the loom, the machine number M1 of the loom whose model is the model S(A) selected in the loom arrangement preparation subroutine is extracted. Next, step
At step 86, a machine number M2 that simultaneously satisfies the following two equations (6) and (7) is extracted from the loom with the machine number M1.

T(A)−DX(P(A(M1))) ≧D2(P(A)) ……(6) T(A)−D1(P(A))≧D2(P(A)) …… (7) Equation (6) calculates the delivery date T (A This is to confirm that the period up to ) is longer than or equal to the number of days D2 (P(A)) required for weaving the fabric of pattern P(A) calculated in the number of machines/beams adjustment subroutine. On the other hand, equation (7) is calculated from the last day D1 (P(A)) predicted by the last day prediction subroutine for predicting the last day yarn input possible for the fabric of pattern P(A) to the delivery date T of the fabric of contract A. This means confirming that the period up to (A) is longer than or equal to the number of days required for weaving D2 (P(A)).

If there is no loom that satisfies these two equations (6) and (7) at the same time, proceed from step 87 to step 88, register the result that the fabric of pattern P (A) cannot be blended among the fabrics of contract A, and then proceed to step 88. Jump to 97. If there are looms that meet the requirements at the same time, in step 89, from among the looms with machine number M2, the latest yarn input date D1 (P(A)) is set to the weaving start date DX(P(A(M2)). ))
Extract the loom number M3 of the earlier loom. This is to create a machine arrangement plan that minimizes the amount of yarn in progress. If such a loom exists, proceed from step 90 to step 91, and enter the machine number M3 of the loom to be installed on the fabric of pattern P(A) among the fabrics of contract A.
arbitrarily decide from among them, and further set the possible weaving start date DX(P(A(M3))) to the scheduled weaving start date DZ
(P(A)). On the other hand, if such a loom as described above is not available, in step 92, the machine number of the loom to be installed on the fabric of pattern P(A) among the fabrics of contract A is arbitrarily determined from among M2. Therefore, M2 is regarded as M3, and the latest date D1 (P
(A)) is the scheduled weaving start date DZ(P(A)).

When the machine number M3 to be installed and the scheduled weaving start date DZ (P(A)) are determined in step 91 or step 92, in either case, the process proceeds to step 93,
According to the following formula (8), the loom is placed on the loom with machine number M3,
The weaving start date DX(P(A) is predicted by predicting the date when the weaving of the fabric of the pattern P(A) scheduled to be woven by this loom will be completed and the weaving of the next fabric can be started.
Update (M2))).

DX (P (A (M2))) = DZ (P (A)) + D2 (P (A)) ... (8) In step 94, the remaining arrangements for the fabric of pattern P (A) are further examined. To create a plan, the value of the variable H is decremented and checked in step 95 to see if it is 0. If it is not 0, the process returns to step 85. Also, when it is 0, the step
Proceed to 96.

In step 96, the following arrangement plan for the fabric of pattern P(A) among the fabrics of contract A is registered. In other words, the registered items for each contract A are pattern P(A), number NA (P(A)), number M3 of the looms corresponding to the number of looms arranged,
Scheduled weaving start date DZ (P
(A)), the number of days required for weaving D2 (P(A)), the number of allocated beams NC (P(A)), the planned amount of yarn to be loaded on one beam V (S(A)), and the preparation of a table arrangement plan. The date of the day is F. Note that this information may be registered for each loom number M3 of the loom. These registrations are made in the mounting film 4c, but these information may also be displayed on the display device 2.

In step 97, P(A) is incremented to examine the next pattern of fabric, and in step 98 it is checked whether this is greater than X'. If not, the process returns to step 83. Next, in step 99, A is incremented to check the fabric of the next contract, and in step 100, it is checked whether this is greater than X, and if not, step 82 is executed.
Return to When A is greater than X, the process of this subroutine is ended and the process returns to the main routine.

[Effects of the Invention] According to the loom layout plan automatic creation device of the present invention,
When creating a loom arrangement plan for textiles,
Using the outputs of the latest yarn input possible date prediction means and the weaving start date prediction means, the machine number determination means and the scheduled weaving start date determination means determine the machine number to be installed on the fabric. and the scheduled start date of weaving the fabric on the loom with this machine number,
It is possible to provide an automatic loom arrangement plan creation device that takes into consideration the scheduled arrival date of yarn and the load on the loom, thereby reducing the amount of yarn in progress and improving the operating rate of the loom. Wear.

In addition, since there is no need to change the table arrangement after weaving has started, there is no need to perform extra "changeover work" or "pulling work", allowing the weaving process to be carried out systematically and efficiently. There is an effect that can be done.
