Description

[Detailed description of the invention]

[Industrial Application Field] When manufacturing woven or knitted products, the present invention examines the amount of yarn in stock according to the type and quality of the product, and allocates the yarn necessary for the product. The present invention relates to an automatic yarn allocating device, and particularly to an automatic yarn allocating device for excess yarn. [Prior art and its problems] The stock amount of raw yarn used in the production of woven or knitted fabrics is managed by type of yarn such as brand, count, hue, etc., and by manufacturing lot. Further, after the raw yarn is spun, it is subjected to processing such as dyeing and twisting, and the inventory amount of both the yarn and the unprocessed yarn is managed. That is, the processed yarn is used as it is in the production of woven or knitted fabrics, but the unprocessed yarn is further dyed or twisted before use. However, there are cases where the unprocessed thread is used as is. For example, when manufacturing a woven fabric, it is necessary to decide which yarn to use for manufacturing the woven fabric, taking into account the type and grade of the woven fabric and the amount of yarn in stock. The process of selecting raw yarns to be used for manufacturing a textile from among various raw yarns based on various conditions is called yarn allocation. The present applicant has already proposed a device for automatically allocating yarn in this manner in Japanese Patent Application No. 144982/1982. However, with regard to the allocation of raw yarn after processing, the allocation was made from only one production lot, which caused the problem that surplus yarn was generated after processing. The surplus yarn is
Unless the stock amount for one manufacturing lot exceeds a certain level, it will not be allocated again, and each time yarn is allocated, the amount increases and sometimes ends up being discarded. An object of the present invention is to provide an apparatus that effectively utilizes such surplus yarn and automatically and efficiently allocates the optimal surplus yarn. [Means for Solving the Problems] The configuration of the automatic yarn allocating device of the present invention will be explained based on FIG. 1. Reference numeral 101 is a surplus yarn inventory registration file. This file is a record of the stock amount of yarns that have been dyed, twisted, etc., and that have become surplus yarn as a result of allocation, for each production lot. Reference numeral 102 is a required yarn registration file in which the type of yarn to be used and the necessary amount thereof are registered for each arrangement of warp and weft yarns constituting each pattern of a woven or knitted product. A contract for ordering woven or knitted products with a customer is called a contract. Although the products related to one contract are of the same type, they may be composed of multiple patterns. In order to construct each pattern, a plurality of yarns are used for each of the warp and weft, and are arranged repeatedly. The order of yarns within this repeating unit is called arrangement as described above. Reference numeral 103 is an input means for inputting the pattern, grade, and production quantity of the woven or knitted product for which yarn is to be allocated. The grade of a product represents the quality of the product. Reference numeral 104 denotes an inventory yarn allocating means, which calculates the amount of yarn to be used for the product of the pattern inputted by the input means 103 based on the production quantity and the required amount of yarn to be used obtained from the required yarn registration file 102. Depending on the grade, the minimum allocation amount is determined for each yarn, the surplus yarn inventory registration file 101 is searched, and when the inventory amount is equal to or greater than the above-mentioned minimum allocation amount, the allocation is made. This is an inventory yarn allocating means that updates the surplus yarn inventory registration file 101 based on the amount of surplus yarn stock. In one embodiment of the present invention, the stock yarn allocating means 104 is configured to allocate yarns preferentially from yarns manufactured at older times. [Operation] When allocating yarn necessary for manufacturing a specific woven or knitted product, first, the pattern, grade, and production quantity of the product are input to the stock yarn allocation means 104 using the input means 103. . Then, this stock yarn allocation means 104 stores the required yarn registration file 1.
02, the type of yarn to be used and the required amount thereof are read for each arrangement of warp and weft yarns constituting each pattern. Then, based on the production quantity obtained from the input means 103 and the required amount of yarn to be used for the product of the pattern obtained from the required yarn registration file 102, reservations are made for each yarn according to the grade. Determine the lower limit amount. Furthermore, the inventory yarn allocation means 104 stores surplus yarn inventory amount registration file 101.
is searched, and when the inventory amount is less than or equal to the lower limit amount for allocation, the allocation is made. Then, the surplus yarn inventory registration file 101 is updated based on this allocation. In one embodiment of the present invention, the inventory of old yarns is reduced by preferentially allocating yarns from yarns manufactured at older times. [Example] Hereinafter, an example of the present invention will be described based on the drawings. In this embodiment, a case will be described in which the present apparatus is used for fabric production. 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
4 is a microcomputer consisting of a CPU (central processing unit), ROM (read-only memory), RAM (random access memory), I/O port, etc., and 4 is an auxiliary storage device such as a magnetic disk or magnetic tape. , each device is connected via an interface circuit. The input device 1 corresponds to the input means 103 and is used to input into the microcomputer 3 the pattern, grade, production quantity, etc. of the fabric for which yarn is to be allocated. The auxiliary storage device 4 stores a surplus yarn file 4a and a fabric file 4b. The surplus yarn file 4a corresponds to the surplus yarn inventory registration file 101, and is yarn that has been processed such as dyeing or twisting, and becomes surplus yarn as a result of allocation. The amount of inventory for each production lot is registered.
The inventory amount of all surplus yarns is stored in a format as shown in FIG. That is, the pages are divided according to the type of yarn and production lot, and each page describes the brand, count, hue, lot number, spinning delivery date, grade, and inventory amount of the yarn. Note that this figure is drawn to facilitate explanation of the configuration of the surplus yarn file 4a, and in reality, the above-mentioned contents are stored in the auxiliary storage device 4 for each type of yarn and manufacturing lot. It can be in any format as long as it is a thing. Among these yarns, it is assumed that the type of yarn with brand name GB, count 1/60, and hue 50010000 is yarn α, and there are other types of yarns such as β, γ, and δ. The textile file 4b corresponds to the required raw yarn registration file 102, and for each pattern of the textile product, it records the following information for each warp and weft arrangement constituting each pattern.
This is a register of the types of yarns to be used and their required amounts, and is used to determine the types and amounts of yarns necessary for manufacturing textiles. All textile products are stored in a format shown in FIG. 4, divided into pages according to their patterns. Each page shows the type of yarn to be used and the unit amount, e.g. 100
The amount of yarn required to produce kg of fabric is stated. For example, the warp of a fabric with pattern A is composed of two arrays a and b, and the weft is composed of three arrays a, b, and c. 100 pieces of this pattern A fabric
It is written that, for example, for warp arrangement a, 25 kg of the above-mentioned yarn α is required in order to produce Kg. Note that this figure is drawn to facilitate explanation of the structure of the textile file 4b, and in reality, the type and amount of raw yarn required will depend on the warp and weft yarns constituting each pattern. It may be in any format as long as it is stored for each array. The ROM of the microcomputer 3 mainly stores the following programs, and is used as the stock yarn allocation means 104. That is, for a fabric of a particular pattern for which the grade and production amount have been input through the input device 1, each type is determined according to the grade based on the production amount and the required amount of yarn to be used obtained from the fabric file 4b. A program that determines the minimum allocation amount for raw yarn, a program that searches the surplus yarn file 4a and makes an allocation only when the inventory amount is equal to or greater than the above-mentioned minimum allocation amount, and This is a program for updating the yarn file 4a. however,
These programs do not need to be stored in the ROM, but may be stored in the auxiliary storage device 4, loaded into the RAM, and then executed. The display device 2 is used to display the allocation result by the microcomputer 3. As mentioned above, the grade of the fabric indicates the quality of the fabric, such as A, B, C,
A certain grade is set for textiles from six grades D, E, and F. The microcomputer 3 used as the stock yarn allocating means 104 allocates yarn for each grade of fabric according to the following conditions. (a) For Grade A textiles, the yarn allocated to the fabric under one contract is limited to the yarn in one production lot. (b) For Grade B fabrics, the yarn allocated to fabrics of one pattern in one contract is limited to yarns from one production lot. (c) For Grade C fabrics, the yarns allocated to the warp or weft of a fabric for one pattern in one contract are limited to yarns from one manufacturing lot. (d) For Grade D fabrics, the yarns allocated to one array of fabrics for one pattern in one contract are limited to yarns from one production lot. (e) For Grade E fabrics, the yarns allocated to one arrangement of warp or weft yarns in one contract are limited to the yarns in one manufacturing lot. (f) For Grade F fabrics, the yarns allocated to one arrangement of warp or weft yarns of fabrics for one pattern in one contract are limited to yarns from one manufacturing lot. . Further, necessary raw yarns are allocated in the order of yarns with oldest spinning deadlines. For sample or test fabrics, lower grade yarns may be assigned. Next, the processing performed by the microcomputer 3 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 type of processed yarn required for the fabric. H (K, W, X, Y) indicates the amount of processed yarn C (K) required for arrangement Y of warp or weft yarns X of the fabric of pattern W. That is, W=1,...
D indicates the pattern of the fabric, X=1, 2 indicates the warp (X=1) and weft (X=2), and Y=1,..., E indicates the warp or weft arrangement, respectively. L=1,...
R is the processed yarn C in the surplus raw yarn file 4a.
(K) indicates a registered page. Z
(K, L) indicates the inventory amount of surplus raw yarn on the Lth page in which processed yarn C (K) is registered, and I indicates the lower limit amount of allocation. The main routine shown in FIG. 5 will be explained. When the pattern, grade, and production amount of a fabric are inputted to the microcomputer 3 from an input device 1 such as a keyboard, the type of processed yarn required for the fabric is determined based on the fabric file 4b stored in the auxiliary storage device 4. C (K) and its required amount H (K, W, X, Y)
(K=1,...,M,W=1,...,D,X=1,2,
Y=1,...,E) is obtained. (Step 1,
2). Then, the first processed yarn C1 is allocated by the surplus processed yarn subroutine shown in FIG. (Steps 3, 4, 5). If the allocation of the processed yarn C1 is successful, the allocation of the next processed yarn is performed with K=K+1 (steps 6 and 7). If it is impossible to allocate processed yarn C (K) because the inventory does not meet the required amount, the microcomputer 3 allocates processed yarns other than surplus raw yarn using a conventional subroutine (not shown). . (Step 8). When the allocation of processed yarn C (K) is completed, K=K
As +1, the next processed yarn is allocated (steps 9 and 7). In this way, the fabric is provided with the necessary texture yarn. Next, using Fig. 6 and Fig. 7, surplus processed yarn C
A subroutine for allocating (K) will be explained. First, the microcomputer 3 searches the surplus raw yarn file 4a, inputs the page in which processed yarn C(K) is registered (step 10), and inputs the page in which processed yarn C(K) is registered.
The pages in which the pages have been registered are rearranged in the order of oldest spinning storage (step 11). Each page rearranged in this way is L=
Initialize it to 1 (step 12) and search from the first page (step 13). First, in step 14, 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 15. In step 15,
Determine whether the grade of the thread on the Lth page is low,
If it is low, the thread on that page is not allocated,
Check the next page as L=L+1 (step
41, 42, 13). If the grade of the yarn on the Lth page is not low, proceed to step 16. If the fabric to be manufactured is a sample fabric or a test fabric, then steps 14 to 16 may be used since lower grade yarns may be used.
Proceed to. Now, in step 16, W=1, X=1,
After initially setting Y=1, in steps 17 to 27, the lower limit amount I of allocation is determined for the previously input fabric grade according to the conditions (a) to (f). That is, when it is determined in step 17 that the grade of the fabric is A, in step 18, W=1, ..., D, X
The sum expressed by the following equation (1) for =1, 2, Y=1, . . . , E is calculated, and this is set as the allocation lower limit amount I. I= 〓 ^W,X,Y H (K, W,
For grade B, in step 20, X=1, 2, Y=1,
..., the sum expressed by the following equation (2) for E is calculated, and this is set as the lower limit amount I of allocation. I= 〓 ^{X, Y} H(K, W, , D, E and F, step
In 22, 24, 26, and 27, the lower limit amount I of allocation is determined by the following equations (3) to (6). I= 〓 ^Y H(K, W, X, Y) ……(3) I= 〓 ^X H(K, W, X, Y) ……(4) I= 〓 ^W H(K, W, X, Y) ...(5) I=H(K, W, , L) is greater than the lower limit amount I, and Z
If (K,L)<I, check the next page with L=L+1 (steps 41, 42, 13), and check Z(K,
L) If ≧I, allocate the thread of that page,
The inventory amount Z (K, L) of the surplus yarn file 4a is changed to a value obtained by subtracting the minimum allocation amount I (step 29). Next, in steps 30-39, it is determined whether further reservations need to be made depending on the grade of the fabric, and if so, steps 30-39 are performed.
Return to 17. In other words, if it is determined that the grade is A in step 30, there is no need to make further allocations, so immediately jump to step 40, register the allocation results, and then return to the main routine described above. do. For grades D, E, or F, check the next sequence with Y=Y+1 (steps 31, 32, 33, 17), and
Or for F, check the weft with X=X+1 (steps 34, 35, 36, 17) and grade B, C, D
Or for F, check the next pattern with W=W+1 (steps 37, 38, 39, 17). If it is no longer necessary to make further allocations for grades other than A, the allocation results are registered in step 40, and the process returns to the main routine. If all pages from 1 to R pages are checked and there is no page whose inventory amount is equal to or greater than the lower limit of allocation, after registering the unallocated result for processed yarn C (K), Return to routine (steps 41, 42, 43). To further explain the above-described surplus processed yarn subroutine using a specific example, let us assume that a certain contract A has a contract of 60 yarns, 30 yarns in the A pattern and 30 yarns in the B pattern. In the case of woolen fabric, one roll is 1.6m wide and 1.6m long.
It is traded in units of 50m. Normally, the weight of one roll is 20 kg, and in this example, the weight ratio of warp and weft is 1:1. Now, as shown in Fig. 4, for a 100 kg fabric of pattern A, 25 kg of yarns α and β are required for warp yarn arrangements a and b, respectively, and yarns α and β of 25 kg are required for weft yarn arrangements a, b, and c, respectively. Assume that 17 kg of yarn α, β, and γ are required. In addition, for a 100Kg fabric with pattern B, 17Kg of yarns α and γ are used in warp arrangements a, b, and c, respectively.
and δ are required, and 25 kg of yarn α and δ are required for weft arrangement a and b, respectively. At this time, the fabric related to contract A includes threads α, β,
γ and δ are 500Kg, 250Kg, 200Kg and
250Kg is required, and a total of 1200Kg of yarn is required. By the way, when the grade of the fabric related to contract A is A, the highest grade, the lower limit amount I for each yarn is the value shown in Table 1. That is, in step 18, if K=1 corresponds to the thread α, then W=1 of H(1, W, X, Y),
2. Equation (1) for X=1, 2, Y=1, ..., E
The sum represented by is the total amount of yarn α required for each arrangement a of the warp and weft of pattern A and the warp and weft of pattern B, and is calculated to be 500 kg. However, in the case of grade B, as shown in Table 2, pattern A and pattern B are distinguished, and for each pattern, for example, yarn α, the stock amount is calculated.
If the weight is 250Kg or more, an allowance will be made. That is, assuming that W=1 corresponds to pattern A and W=2 to pattern B, for W=1, formula (2)
The sum represented by is the total amount of yarn α required for each arrangement a of the warp and weft of pattern A, and is
It is calculated as 250Kg. Also, step
After returning to step 17 from 37, 38, and 39, in step 20 again, for W=2, the sum is pattern B
The total amount of yarn α required for each warp and weft arrangement a is calculated to be 250 kg. Below, regarding grades C, D, E and F,
As shown in Tables 3, 4, 5, and 6, respectively, the lower limit amount I for each yarn is determined. Therefore, for example, for yarn α, whether or not it can be allocated is determined for each grade based on the following lower limit amount of allocation. That is, in the case of Grade C or F, if the inventory amount is 100Kg or 150Kg or more, reservation will be made. In addition, in the case of grade D or E, if the inventory amount is 250 kg or more, an allowance will be made. In other words, in the past, the allocation was made from one manufacturing lot, so for example, for yarn α, the allocation was not made unless the inventory of surplus yarn was 500 kg or more, just like in the case of grade A.
It was not possible to effectively utilize raw yarn from lots with an inventory of less than 500 kg. On the other hand, in the case of grades B, C, D, E, or F, if the stock amount is 100Kg or more, or 150Kg or more, or 250Kg or more, an allowance will be made, so surplus yarn can be used effectively. be able to.

[Table] [Effect of the invention] According to the automatic yarn allocation device of the present invention, by simply inputting the pattern, grade, and production amount of a specific woven or knitted product, each yarn is allocated according to the grade. Since the lower limit amount is automatically determined and yarn is allocated, the manufacturing period is shortened, surplus yarn can be used effectively, and the optimal amount of surplus yarn can be allocated efficiently. . In addition, by simply registering the inventory amount of each surplus yarn in the surplus yarn inventory registration file, the contents of the file will be automatically updated after the required yarn is allocated. Even when a large number of yarns are registered, it is possible to allocate the optimal surplus yarn without requiring any effort. In addition, by configuring the stock yarn allocating means to allocate yarns with priority from yarns manufactured in the oldest manufacturing period, old excess yarn can be reduced from the inventory, making it easier to manufacture woven and knitted products. There will be no waste.
