FIG. 2 is an explanatory view of the weft stocker 30. In the weft stocker 30, various kinds of wefts are stored as one package of four cheeses, and a package of a necessary weft is automatically released from the stocker control computer 28 in accordance with an instruction. In addition, cheese means what wound the weft around the bobbin, 1 cheese means 1 cheese. Then, the package that has been delivered is transported by a factory worker to a designated loom by a dedicated cart, and attached to the loom.

The operation state of the weft supply instruction device 10 having the above configuration will be described with reference to the flowchart of FIG. In addition,
All the following operations are performed for each loom.

In step a1, weft supply information (a combination pattern of a plurality of types of wefts to be supplied and a supply time point at which the supply is performed is determined. Then, the process proceeds to step a2. This weft supply information is determined. The method will be described later.

In step a2, the weaving operation by the loom is started. Then, the process proceeds to step a3.

In step a3, the operation status of the loom, which is information from the microcomputer 12, is fetched in real time.
Then, the process proceeds to step a4.

In step a4, it is determined whether or not the warp used in the loom has ended, and if so, the operation is ended. If not, the process proceeds to step a5.

In step a5, the monitoring unit collecting device 20 calculates the current weaving length based on the operating state of the loom. The weaving length is determined by the operation state of the loom, and in the case of this embodiment, the weaving length is the supply time described in the claims. In other words, the longer the weaving length, the longer the supply time. Then, the process proceeds to step a6.

In step a6, the supply point obtained in step a1 is converted into a weave length, and it is determined that the weft is insufficient before the current weave length reaches the converted weave length. Proceed to step a7, otherwise return to step a3.

In step a7, the weft is unloaded, and the process returns to step a1.

Next, based on the flowchart of FIG.
The operation in step a1, that is, a method of determining the weft supply information when a plurality of types of wefts are used in the same loom will be described.

In step b1, the number M of weft types (hereinafter referred to as yarn types) and the usage ratio are input. Then, the process proceeds to step b2. Here, the thread types are A, B, C,
If there are four types of D, M = 4, and the usage ratio is A: B: C: D = 16: 10: 4: 2.

In step b2, the consumption time t of one cheese of the maximum use thread is calculated. That is, since the maximum used yarn is A here, the calculation of the consumption time t of one cheese of A is performed as follows.

[0050] The weaving width has the same meaning as the weft length required for one driving of the loom described in the claims, and the expected operating rate is the operating rate calculated from the actual operating rate of the loom up to now. Say. Then, the process proceeds to Step b3.

In step b3, a calculation unit time k is calculated. The calculation unit time k is a reference time for calculating how much each yarn type is consumed in the calculation unit time k by equally dividing the consumption time t. Here, k = t
/ 8, but this can be set arbitrarily, and the greater the number of equally divided parts, the finer the management becomes. And
Proceed to step b4.

In step b4, the calculation end time kma
The calculation of x is performed as follows.

[0053] kmax refers to the time at which one operation is completed, and kmax is the sum of the calculation unit times k. That is, k + k +
k +... = kmax. Then, the process proceeds to Step b5.

In step b5, the following steps are executed for each calculation unit time k. Then, the process proceeds to step b6.

In step b6, A, B,
The following steps are performed in the order of C and D. Then, the process proceeds to step b7.

In step b7, the used amount Y is subtracted from the remaining amount Z of the weft yarn to obtain a new remaining amount Z. Here, the used amount Y refers to the amount of yarn consumed during the calculation unit time k. This usage amount Y is set in advance for each yarn type. Then, the process proceeds to step b8.

In step b8, the remaining amount Z of the weft is Z
It is determined whether ≦ 0, and if Z ≦ 0, the process proceeds to step b9.
If Z> 0, the process proceeds to step b13.

In step b9, the remaining amount Z of the weft yarn
Is Z ≦ 0, the weft yarn is counted as a yarn type to be supplied. Then, the process proceeds to Step b10.

In step b10, the remaining amount Z of the weft is updated. That is, the yarn amount for one cheese is added to the remaining amount Z, and the process proceeds to step b11.

In step b11, it is determined whether or not the thread types to be supplied have been completed in one supply unit. If not, the process proceeds to step b13. If not, the process proceeds to step b12. The unit of one-time supply can be set arbitrarily, but here, it is assumed to be eight packages, ie, two packages (see FIG. 2).

In step b12, the supply combination pattern and supply point are determined, and the flow advances to step b13.
The determination of the supply combination pattern is defined as a single supply unit (8 channels).
(For example, A = 2 cheeses, B = 4 cheeses, C = 2 cheeses, D =
0 cheeses, for a total of 8 cheeses). Determining the supply point means
As described above, this refers to the determination of the time at which the supply units are made once and supplied to the loom. However, the supply point here is not one point (time) of the actual flowing time, but one point of the weaving length (supply time) determined from the operation state of the loom described above. If the supply combination pattern and the supply point can be determined, as described above, it is possible to know when and how much weft can be supplied to the loom. The determination of the supply combination pattern and the determination of the supply point will be described later in detail.

In step b13, when the thread type is updated and all the thread types have been calculated, step b1 is executed.
Go to step 4, otherwise return to step b6.

In step b14, the calculation unit time k
= Kmax, and the process returns to step b5 if k is not kmax.

Here, the determination of the supply combination pattern and the determination of the supply point in step b12 will be described in detail with reference to FIGS. These determinations are made by the label personal computer 26.

(1) Determination of Supply Combination Pattern As described above, there are four types of wefts, A, B, C, and D, and the usage ratio is A: B: C: D = 16: 1
0: 4: 2. If this is expressed in terms of the number of cheeses, A is 16 cheeses, B is 10 cheeses, C is 4 cheeses, and D is 2 cheeses, for a total of 32 cheeses. It is assumed that the 32 cheeses are transported four times. That is, one package transports eight packages, that is, two packages.

(2) Determination of Supply Time The supply time is determined by the above-mentioned calculation unit time k. Then, by this, the thread of A is consumed every four timings,
B is consumed every 5/32 timing, C is consumed every 18 timings, and D is consumed every 32 timings. Here, one timing is a time formed by collecting a plurality of calculation unit times k, and when k = t / 8, one timing = 16 × k.

(3) Specific determination method A specific determination method will be described. FIG. 5 is a schematic diagram of the calculation.
The vertical direction indicates the yarn type, and the horizontal direction indicates the supply time.

(A) The first supply combination pattern is determined as follows.

In the flowchart of FIG. 4, once the supply units have been prepared at step b11, the process proceeds to step b12.
The content of a single supply unit in step b11 is A
= 2 cheeses, B = 2 cheeses, C = 2 cheeses, D = 2 cheeses
And a total of 8 cheese supply combination patterns. This supply combination pattern is changed from step b5 to step b.
It is inevitably determined to repeat step 14. In the calculation outline diagram of FIG. 5, it is the part of the transport number.

The first supply point is determined as follows.

Since the first supply combination pattern needs to be supplied before the loom starts to work, the first supply timing = 1 is unconditionally set.

(B) The second supply combination pattern is determined as follows.

In the flowchart of FIG. 4, once the supply units are completed in step b11, the process proceeds to step b12.
The content of a single supply unit in step b11 is A
= 6 cheeses, B = 2 cheeses, C = 0 cheeses, D = 0 cheeses
And a total of 8 cheese supply combination patterns. In the calculation outline diagram of FIG. 5, it is the part of the transport number.

The second supply point is determined as follows.

In the first supply combination pattern, A
A is the earliest consumed among the yarn types of ~ D. A = 2 cheeses, B = 2 cheeses, C = 2 cheeses, D
= 2 cheeses are supplied, the amount of each of these yarns and the usage ratio (A:
B: C: D = 16: 10: 4: 2). Therefore, A = calculation unit time k in which 2 cheeses are consumed
(4 timings) is the second supply point.

(C) The third supply combination pattern is determined as follows.

In the flowchart of FIG. 4, once the supply units are completed in step b11, the process proceeds to step b12.
The content of a single supply unit in step b11 is A
= 6 cheeses, B = 4 cheeses, C = 2 cheeses, D = 0 cheeses
And a total of 8 cheese supply combination patterns. In the calculation outline diagram of FIG. 5, it is the part of the transport number.

The third supply point is determined as follows.

In the second supply combination pattern, A
B is the earliest consumed among the yarn types of ~ D. This is because the sum of the yarn amounts of the wefts supplied by the first supply combination pattern and the second supply combination pattern is A
= 8 cheeses, B = 4 cheeses, C = 2 cheeses, D = 2 cheeses
And the use amount (A: B: C: D = 1)
6: 10: 4: 2). Therefore, B = 4
Calculation unit time k to which the cheese is supplied (13 timings)
Is the second supply point.

(D) The fourth supply combination pattern is determined as follows.

In the flowchart of FIG. 4, once the supply units are completed in step b11, the process proceeds to step b12.
The content of a single supply unit in step b11 is A
= 6 cheeses, B = 2 cheeses, C = 0 cheeses, D = 0 cheeses
And a total of 8 cheese supply combination patterns. In the calculation outline diagram of FIG. 5, it is the part of the transport number.

The fourth supply point is determined as follows.

In the third supply combination pattern, A
A is the earliest consumed among the yarn types of ~ D. This means that the sum of the yarn amounts of each weft supplied by the preceding three supply combination patterns is A = 10 cheeses, B = 8 cheeses,
C = 2 cheeses and D = 4 cheeses, and it is determined from this yarn amount and the usage ratio (A: B: C: D = 16: 10: 4: 2). Accordingly, the calculation unit time k (20 timings) at which A = 10 cheeses are supplied is the fourth supply point.

(4) Results Accordingly, the above results are summarized in the calculation result table of FIG. The uppermost row in the table of FIG. 6 indicates the transport number indicating the number of times of transport, the second to fifth rows in the table indicate the amount of each yarn type carried out by one transport, and the lowermost row in the table indicates each transported number. Supply points are shown. Thus, for example, in the case of the second transport, the yarn types transported at four timings are A and B, where A is 6 cheeses and B is 2 cheeses, for a total of 8 cheeses. Is transported as one supply unit.

As described above, with the weft supply instructing device 10 of this embodiment, the consumption of the weft consumed by the loom is calculated in advance, and the operating rate of the loom is always taken in. Because it is a method of supplying weft,
The weft is always supplied to the loom, and the operating rate does not decrease.

In the above embodiment, a plurality of types of wefts are used.
If = 1 and the calculation of the usage ratio is omitted, one kind of weft is always supplied to the loom without excess or deficiency.

FIG. 7 is a flowchart of the supply instruction device of the second embodiment. This weft supply instruction device is a flowchart of a weft supply operation performed by a factory before a holiday. Before the holiday, the amount of weft consumed by operation of the loom during the holiday is calculated in advance, and To supply weft yarns. Thus, even if the factory enters a holiday and no workers are present and the weft is not supplied, the loom is supplied with the weft in advance, so that the loom can operate without any problem during the holiday.

At step c1, it is determined whether or not it is before a holiday. If it is not before a holiday, the process shifts to a weekday retrieval program similar to the first embodiment. If it is before the holiday, the process proceeds to step c2.

In step c2, the expected holiday weave length and the required amount of weft are calculated. Then, the process proceeds to step c3. That is, in step c2, FIG.
In the flowchart of FIG. 5, the end time of the calculation end time kmax is not set on the current day, but the time including the holiday is included in the calculation unit time k, and the end time of the calculation end time kmax is set as the end time of the holiday. As a result, the amount of weft consumed on holidays is calculated. The calculation method is the same as the flowchart in FIG.

In step c3, a required amount of weft is unloaded. In this case, to release the weft for holidays,
The amount to be delivered may be divided in advance and distributed so that a large amount of wefts is not delivered at one time. Then, the process ends.

[0091]

As described above, according to the weft supply instructing device for a loom of claim 1 of the present invention, the instructing means sets the supply time measured by the measuring means before the supply time calculated by the computing means. Then, an instruction is made for each loom to replenish the supply combination pattern calculated by the calculation means.
