Description

Detailed Description of the Invention [Industrial Application Field] The present invention is directed to the production of woven or knitted products, depending on the type and quality of the product, from which raw yarn necessary for the product is stocked. This invention relates to an automatic yarn allocating device that checks yarn inventory and allocates yarn.

[Prior art and its problems] Raw yarn used for manufacturing woven or knitted fabrics, etc.
Inventory quantities are managed by yarn type, such as brand, count, and hue, and by production lot. In addition, the raw yarn is
After being spun, processing such as dyeing and twisting is performed, and the inventories of both the processed and unprocessed yarns are managed. The process of selecting a specific yarn for weaving or knitting from among these yarns in stock is called yarn allocation.

Now, taking the case of weaving as an example, raw yarn that has been washed can be directly put on a loom without further dyeing. When raw yarn that has not been dyed is used, it may be woven after dyeing, or it may be dyed in the woven fabric state after weaving. When threading a doubled yarn obtained by twisting a plurality of single yarns together on a loom, it is necessary to twist the single yarn before weaving. Therefore, when allocating yarn, it is necessary to decide which yarn to use, taking into account not only the amount of yarn in stock, but also these processes. Moreover, the types and grades of textiles are now diversifying, and the textiles use a wide variety of yarns that have been dyed, twisted, etc., so the allocation conditions have become complicated. Therefore, even for a skilled person, it takes a great deal of time to allocate the appropriate yarn, making it difficult to allocate the necessary yarn from stocked yarn without waste and accurately.

Therefore, an object of the present invention is to provide a device that, by simply inputting the type of processed yarn necessary for each woven or knitted fabric, checks the stock amount and automatically allocates the most suitable raw yarn. It is in.

[Means for Solving the Problems] The configuration of the automatic thread allocating device of the present invention will be explained based on FIG. 1.

101 is an inventory registration file, which includes dyeing processing,
The inventory amount is registered for both the yarn after processing such as twisting and the yarn before processing. Reference numeral 102 denotes a storage means that stores the correspondence between the type of yarn after processing and the type of yarn before processing. This correspondence relationship means that yarn A after processing is dyed yarn A ₁ , and yarn B after processing is yarn B ₁ and yarn dyed.
This indicates that it is made by twisting B ₂ together.
Reference numeral 103 is an input means for inputting the type and amount of processed yarn required for one manufacturing unit of a specific woven or knitted product. Here, one manufacturing unit refers to one unit of a product that can be continuously manufactured by a manufacturing device, and corresponds to one roll of textiles, for example.
Further, reference numeral 104 denotes an inventory yarn allocating means, which searches the inventory registration file 101 for the necessary processed yarn inputted by the input means 103, checks the inventory amount, and determines whether the inventory amount is the required amount. If the requirement is satisfied, this processed yarn is allocated, and if the stock amount is less than the required amount, the correspondence storage means 102 is searched to find out the type of unprocessed yarn that corresponds to the processed yarn. , searches the inventory registration file 101 for the unprocessed yarn, examines the inventory, allocates the unprocessed yarn, and updates the inventory registration file 101 based on these allocations. . The amount of inventory registered in the inventory amount registration file 101 is changed to a value obtained by subtracting the required amount.

In one embodiment of the present invention, the inventory amount is registered for each manufacturing lot of yarn in the inventory amount registration file 101, and the inventory yarn allocation means 10
4 is configured to preferentially allocate yarns from yarns manufactured at an older time.

In another embodiment, the stock yarn allocating means 104 allocates from only one production lot of yarn when allocating processed yarn, and when allocating unprocessed yarn, It is configured so that reservations can be made from multiple manufacturing lots.

[Operation] When allocating yarn necessary for manufacturing a specific woven or knitted product, first, input means 103 inputs the type of processed yarn that can be used in its original state and the required amount. Thread securing means 104
Enter. Then, the stock yarn allocation means 104
is the stock quantity registration file 101 for that yarn.
Search for the amount of inventory, check the amount of inventory, and if the amount of inventory satisfies the required amount, reserve. If the stock amount is less than the required amount, the stock yarn allocation means 104 searches the correspondence storage means 102 to find out the type of unprocessed yarn corresponding to the yarn, and stores the unprocessed yarn in stock. The quantity registration file 101 is searched, the inventory quantity is checked, and an allocation is made. Therefore, the manufacturing period can be shortened by preferentially allocating threads that can be used immediately as they are. The inventory registration file 101 is then updated based on these allocations.

In one embodiment of the present invention, the inventory of old yarns is reduced by preferentially allocating yarns from yarns manufactured at older times.

Since the processed yarn is used as is in the production of woven or knitted products, it is better to allocate from only one production lot of yarn to avoid unevenness in the product. Therefore, it is preferable that the unprocessed yarn is used for manufacturing woven or knitted fabrics after being subjected to processing such as dyeing.
Even if it is possible to allocate from multiple production lots, unevenness in the product is less likely to occur, and stock yarn can be used efficiently.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

In this example, a case will be described in which the present apparatus is used for manufacturing textiles.

After the raw yarn is spun, it is used after being subjected to processing such as dyeing and twisting, and the processed yarn is called processed yarn, and the unprocessed yarn is called fabric yarn. The stock amount of these yarns is managed by type and production lot.

Figure 2 shows an overview of the device of this embodiment, where 1 is an input device such as a keyboard, 2 is a display device such as a CRT display or printer, and 3 is a CPU.
(central processing unit), ROM (read-only memory), RAM (random access memory), I/O ports, etc. 4 is an auxiliary storage device such as a magnetic disk, magnetic tape, etc. The devices are connected via an interface circuit.

The input device 1 is used to input the type of fabric, its quantity, delivery date, etc. to the microcomputer 3.

The auxiliary storage device 4 includes textile information 4a used to determine the type of raw yarn necessary for manufacturing the textile and the amount of raw yarn required for one roll of textile, and the correspondence between processed yarn and fabric yarn. Processed yarn-fabric yarn correspondence relationship 4b,
An inventory amount registration file 4c is stored in which the inventory amount and the like are registered for each type of yarn and manufacturing lot.

First, the inventory registration file 4c will be explained. The stock amount of all yarns is shown in the format shown in Figure 3, that is, the pages are divided by type of yarn and manufacturing lot, and each page contains the brand, count, hue, and lot number of the yarn. , the spinning delivery date, and the amount in stock are recorded, as well as the tailoring and grade of the yarn. Note that FIG. 3 is drawn to facilitate the explanation of the structure of the inventory quantity registration file 4c, and in reality, the above-mentioned contents are stored in the auxiliary storage device 4 for each type of yarn and production lot. It can take any form as long as it is something.

Figure 4 shows the correspondence relationship 4b between fabric yarn and processed yarn. For example, the brand, count, and hue are GB,
1/60・50010000 processed yarn is dyed fabric yarn with brand, count, and hue as GB・1/60・10000000, and brand, count, and hue as GB・2/1/48・
The processed yarn of 85023503 is GB, 1/48, 10000000 and GB, 1/48, in terms of brand, count, and hue, respectively.
14811211 fabric threads twisted together.

The ROM of the microcomputer 3 mainly stores the following programs, and is used as an inventory yarn allocation means. That is, a program that uses textile information 4a to determine the type of raw yarn necessary for manufacturing a certain specific textile and the amount of raw yarn required for one roll of textile inputted by the input device 1, and the processed yarn-fabric yarn correspondence relationship 4b. is used to find the fabric yarn corresponding to the processed yarn, and the inventory amount registration file 4c is searched to check the inventory amount of raw yarn, taking into consideration the relationship between the required amount and inventory amount, and conditions such as the type and grade of the fabric. This is a program that allocates the optimal thread.
However, these programs do not need to be stored in ROM, but can be stored in auxiliary storage device 4.
You may also load it into RAM and then execute it.

The display device 2 is used to display the allocation result by the microcomputer 3.

The microcomputer 3 used as stock yarn allocating means allocates yarn according to the following conditions.

If the required raw yarn is a processed yarn, the processed yarn is first allocated preferentially, and if the processed yarn cannot be allocated, the fabric yarn that is the source of the processed yarn is allocated.

Necessary raw yarn is allocated in order from yarn with the oldest spinning delivery date.

When dyeing is applied to fabric threads, tailoring for dyed threads,
For example, allocation is made only from yarns that have been tailored using a polypropylene coat or the like.

For sample or test fabrics, lower grade yarns may be assigned.

For processed yarns, allocation is made from only one lot, and for fabric yarns, allocation can be made for multiple lots, for example, up to three lots. However, even in the case of fabric yarn, if it is used for warp threads, only one lot is reserved, and if it is dyed, only one lot is reserved if the required quantity is small, and if the quantity is large, multiple lots are reserved, for example, up to 2 lots. It can be performed.

Next, the processing performed by the microcomputer will be explained using the flowcharts shown in FIGS. 5 to 7.

First, the symbols used here will be explained. C(1) to C(M) indicate the types of processed yarns required for the woven fabric, and H(1) to H(M) indicate the required amount of each processed yarn for one roll of the woven fabric. Also, W(1) ~ W
(T) indicates the type of fabric yarn corresponding to processed yarn C (K), and I(1) to I(T) are the required amounts of each fabric yarn for one roll of fabric. L=1,...,R indicates the page where the processed yarn C(K) is registered in the inventory registration file 4c, and L=1,...,S indicates the page where the fabric yarn W(K) is registered in the inventory registration file 4c. This shows the page that was created. Z(K,L) indicates the stock amount of the Lth page of yarn where processed yarn C(K) is registered, and X(K,L) indicates the amount of yarn on the Lth page where fabric yarn W(K) is registered. indicates the amount of yarn in stock. Further, P indicates the number of manufacturing lots.

The main routine shown in FIG. 5 will be explained.

When the type of fabric is input to the microcomputer 3 from the input device 1 such as a keyboard, the type of processed yarn C (K) ( K=
1,...,M) and its required amount H(K) (K=1,
..., M) is obtained (steps 1 and 2). Then, allocation of the first processed yarn C(1) is attempted by the processed yarn subroutine shown in FIG. 6 (steps 3, 4, and 5). If the allocation of processed yarn C(1) is successful, allocation of the next processed yarn is attempted with K=K+1 (steps 6 and 7). If it is impossible to allocate processed yarn C (K) because the stock amount does not meet the required amount, the microcomputer 3 uses the processed yarn-fabric yarn correspondence relationship 4b stored in the auxiliary storage device 4. Then, the fabric yarn W(K) (K=1, . . . , T) corresponding to the processed yarn C(K) is determined (step 8). Then, the fabric yarn W(K) (K=1, . . . , T) is allocated using the fabric yarn subroutine shown in FIG. 7 (steps 9, 10, 11, 12). When the allocation of the fabric yarn W(K) is completed, an attempt is made to allocate the next processed yarn C(K) with K=K+1 (steps 10 and 7). In this way, first an attempt is made to allocate a processed yarn, and only if this allocation is not possible, a fabric yarn corresponding to the processed yarn is allocated.

Next, the processed yarn subroutine for applying the processed yarn will be explained using FIG.

First, the microcomputer 3 searches the inventory registration file 4c and inputs the page in which the processed yarn C (K) is registered (step 13).
The pages in which (K) is registered are rearranged in descending order of spinning delivery date (step 14).

Each page rearranged in this way is L=
Initialize it to 1 and search from the first page. First, in step 17, it is determined whether the fabric to be manufactured is a sample fabric or a test fabric. If it is not a sample fabric or a test fabric, proceed to step 18. In step 18, if the grade of the thread on page L is low, the thread on that page is not allocated and L=
Check the next page as L+1 (step 22,
23, 16). If the grade of the thread on the Lth page is not low, in step 19 it is determined whether the stock amount Z(K,L) of the thread on the Lth page is greater than the required amount, and Z(K,L)< In the case of H(K), L=
Check the next page as L+1 and find Z(K,L)≧H
In the case of (K), allocate the yarn on that page, change the inventory amount Z (K, L) in the inventory amount registration file to the value obtained by subtracting the required amount H (K), and register the allocation result. (Steps 20 and 21).

If the fabric to be manufactured is a sample fabric or a test fabric, a yarn of a lower grade may be used, so proceed from step 17 to step 19, and calculate the inventory amount Z (K, L) for that page in the same way as above. Compare the required amount H(K) and if Z(K,L)<H(K), do not allocate the thread for that page and check the next page with L=L+1 (step 22, 23, 16), Z
If (K,L)≧H(K), the yarn for that page is reserved and the inventory amount Z(K,
Change L) to the value obtained by subtracting the required amount H (K),
Register the allocation results (steps 20 and 21). 1~
If all the pages up to the R page are checked and there is no page whose required quantity satisfies the stock quantity, an unallocable result is registered (steps 22, 23, 24).

Next, a fabric thread subroutine for pulling fabric threads will be explained using FIG.

First, the microcomputer 3 searches the inventory registration file 4c, inputs the page in which the fabric yarn W(K) is registered (step 25), and inputs the page where the fabric yarn W(K) is registered.
The pages in which (K) is registered are rearranged in descending order of spinning delivery date (step 26).

By initializing L=1 and the number of lots P=1 (step 27), each page rearranged as described above is examined starting from the first page. First, step
In step 29, it is determined whether the fabric to be manufactured is a sample fabric or a test fabric. If it is not a sample fabric or a test fabric, proceed to step 30, and in step 30, it is determined whether the grade of the yarn on that page (page L) is low, and if the grade is low, the yarn on that page is not allocated. Then, the next page is checked with L=L+1 (steps 42, 43, 28). If the grade of the thread on the Lth page is not low, proceed to step 31. If the fabric to be manufactured is a sample fabric or a test fabric, it is possible to allocate a yarn of a lower grade, so proceed from Step 29 to Step 31 without making a judgment in Step 30.
Proceed to. In step 31, it is determined whether dyeing processing is to be performed. If the fabric thread is to be dyed, in step 32, it is determined whether the thread on the L page is tailored for dyed thread, and if it is not tailored for dyed thread, do not allocate the thread on that page. Examine the next page (steps 42, 43, 28),
In the case of tailoring for dyed yarn, proceed to the next step 33. In step 33, the stock amount of thread on the Lth page is
Determine whether (K, L) is greater than the required amount I(K). In step 33, X(K,L)≧I
In the case of (K), allocate the yarn for that page and change the inventory amount X (K, L) in the inventory amount registration file to the required amount I
Change the value by subtracting (K) and register the allocation result (steps 34 and 35). X(K,L)<I
In the case of (K), proceed to step 36. step 36
In this case, when the fabric yarn W(K) is used as a warp yarn, only one lot can be allocated, so the next page is examined without allocating the yarn of that page (steps 42, 43, and 28). The fabric thread W
If (K) is used as weft, step
Proceed to 37. When the fabric thread W (K) is dyed,
The required amount I(K) is a certain amount, for example 50Kg
If it is less than 1 lot, we will only allocate from 1 lot.
Examine the next page without assigning the thread for that page (steps 45, 42, 43, 28). If the required quantity I(K) is equal to or greater than the predetermined quantity 50 kg, it is possible to allocate up to a plurality of lots, so if the number of lots is P=1, proceed to step 39. However, it is preferable to limit the number of lots to two so as not to increase the color difference between lots. If the number of lots is P=2, the next page is examined without allocating the thread of that page (step 46, 42, 43, 28). If the fabric yarn cannot be dyed, it is possible to allocate up to multiple lots, for example, if up to 3 lots can be allotted, then in step 38, if P = less than 3, proceed to step 39, and if P = 3. If so, the next page is examined without allocating the thread for that page (steps 42, 43, 28).

In step 39, all the yarn for that page is reserved, and the required amount I(K) is changed to a value obtained by subtracting the inventory amount X (K, L) for that page.In step 40, the inventory amount registration file is changed to X. (K,L)
=0. Then, set P=P+1 (step 41) and check the next page (step 42,
43, 28). In this way, if allocation is not possible even after checking all pages from page 1 to page S, a result of non-allocation is registered (step 44).

As a result of allocating for each roll of fabric as described above, for example, when manufacturing 5 rolls of fabric, there are 3 rolls worth of processed yarn and 5 rolls worth of fabric yarn as raw threads that can be allocated. , the processed yarn is applied to the first three rolls of fabric, and the fabric yarn is applied to the remaining two rolls.

In this embodiment, the inventory registration file 101 and the correspondence relationship storage means 102 described in the section for solving the problem are replaced by the inventory registration file 4c and processed yarn stored in the auxiliary storage device 4. They respectively correspond to the fabric yarn correspondence relationship 4b. In addition, inputting the type and amount of processed yarn required for one manufacturing unit of woven or knitted products is as follows:
The microcomputer 3 automatically performs this process based on the types of fabrics and their required quantities input through the input device 1. That is, the input means 103 and the stock yarn allocation means 104 are included in the microcomputer 3. Furthermore, the configuration may be such that the required yarn is directly input from the input device 1.

In this example, we have described the case where the raw yarn necessary for manufacturing textiles is processed yarn. However, when dyeing the fabric yarn as it is in the loom after weaving, such as when dyeing the woven fabric after weaving, it is possible to It may be constructed so that fabric threads are pulled against it.

[Effect of the invention] According to the automatic yarn allocating device of the present invention, by simply inputting the type and amount of yarn required for one production unit of a specific woven or knitted fabric, processing is performed and the yarn is processed as is. We prioritize yarns that can be used in this condition, and if processed yarns cannot be allocated, we allocate unprocessed yarns that correspond to the processed yarns, shortening the manufacturing period and reducing inventory. Simply register the stock amount of each yarn in the quantity registration file, and once the required yarn is allocated, the contents of that file will be automatically updated, so you can easily register a large number of yarns. Even if there is a problem, the most suitable yarn can be allocated without any effort, and the yarn in stock can be processed efficiently.

In addition, by configuring the inventory yarn allocating means to allocate yarns preferentially from yarns with older production times, the inventory of older yarns can be reduced.
Waste is eliminated in the production of woven and knitted products.

Furthermore, when allocating yarn after processing, the allocation is made from only one manufacturing lot, and when allocating unprocessed yarn, the allocation can be made from multiple manufacturing lots. This allows stock yarn to be used effectively.
