Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for improving the operating rate of a loom that manufactures textiles, and more specifically, the present invention is an apparatus for improving the operating rate of a loom that manufactures textiles. The present invention relates to a device that improves the overall operating rate by operating a machine.

(Prior Art) Conventionally, efforts to improve the operating rate of looms have been directed solely to improving the operating rate of individual looms themselves. For example, by properly maintaining the loom, the number of warp and weft breaks can be reduced, thereby reducing downtime. The aim is to improve the thread piecing skills of the thread holders (also called stand holders) and shorten the thread piecing time.
Various measures have been taken to improve the quality of the loom, such as applying a sizing process to the warp yarns to reduce friction when the warp and weft intertwine, thereby reducing warp and weft breakage and reducing downtime. We have been aiming to improve the operating rate. In addition, based on many years of experience in operating looms, efforts have been made to optimize the number of looms and the number of loom holders, and by determining the number of looms that each loom holder can splice, efforts are being made to improve the operating rate of the entire loom fleet. It's here.

In addition, Japanese Patent Application Laid-Open No. 58-201105 discloses a process management method that automatically issues work instructions in response to the work progress status of the process, thereby minimizing work idle time, process delays, etc. has been done. This process control method, as described in the above publication,
"In a production process where a desired product is completed by sequentially adding work via multiple work stations, a production schedule planning device that determines and outputs production schedule information regarding the product to be produced, and By connecting through a local network with each work progress management device that is installed in the production schedule and instructs and manages the progress of each work based on the production schedule information, the production schedule planning device can manage the progress of each work. The above-mentioned production schedule information is supplied to the equipment, and based on the same information, each work progress management equipment supplies the relevant performance information for each work to other same equipment and the above-mentioned production schedule planning equipment, and each work station This method determines the priority of the next work in the process and instructs and manages the progress of the work. In other words, the status of work in progress at work stations in the subsequent process is grasped, and if the number of work in progress is less than a predetermined number,
This is to give priority to the work in the previous process related to the subsequent process.

(Problems to be Solved by the Invention) However, all of the above-mentioned measures to improve the loom operating rate are effective to some extent on the premise that both the warp and weft yarns are continuously supplied without interruption. If there are frequent stoppages while waiting for yarn supply, even if such measures and efforts are taken, it will become meaningless. In other words, the raw yarn processing process (dyeing and twisting of raw yarn), which is a pre-process of the weaving process, and the supply of raw yarn from the spinning process to the weaving process are not always carried out as planned, resulting in delays of one to two weeks.
The reality is that delays of more than a month sometimes occur. Furthermore, with the recent diversification of textiles and the trend toward small-lot production of a wide variety of products, it has become necessary to use different types of yarn for each loom, and the types of yarn used have increased significantly. ,
The waiting time for warp beams and weft threads has become increasingly severe, and this has forced an increase in the amount of time the loom is stopped.

Furthermore, the process control system described above cannot be directly applied to the loom process. That is, in reality, the yarn processing process described above does not necessarily exist in the same factory as the weaving process, and on the contrary, in many cases, the yarn is purchased. In such a case, it is not possible to manage the yarn processing process and the weaving process as a series of processes, so even if you understand the necessary yarn from the in-process status of the weaving process, which is the subsequent process, and order it, the actual problem is that the yarn processing process and weaving process cannot be managed as a series of processes. If the looms do not arrive, the looms will stop working.

On the other hand, if the yarn is arranged earlier to prevent the loom from stopping, the number of stops due to waiting for yarn will be reduced, but it will increase the inventory of yarn in progress in the weaving process, resulting in a huge amount of money and money. This poses other major problems, such as the waste of space for storing yarn.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to suppress the unfinished stock of raw yarn in the weaving process, dynamically grasp the raw yarn supply status to the weaving process, and adjust the rotation speed of the loom based on this. The object of the present invention is to provide a loom operating rate improvement device that improves the operating rate of the entire loom group by controlling the looms.

(Means for Solving the Problems) Hereinafter, the configuration of the loom operating rate improving device of the present invention will be explained based on FIG. 1.

Reference numeral 100 denotes a loom yarn amount measuring means for measuring the amount of yarn set in each of a plurality of looms for each warp and weft.

Reference numeral 101 denotes yarn inventory monitoring means for determining the inventory amount of warp and weft yarns.

Reference numeral 102 denotes a means for ascertaining the scheduled arrival date and time of yarn for ascertaining the warp and weft delivery dates.

Reference numeral 103 denotes a warp beam inventory grasping means for grasping the amount of warp beams in stock.

Reference numeral 105 indicates the current amount of weft in progress obtained from the loom in-process yarn amount measuring means 100, the weft inventory amount for each loom obtained from the yarn inventory grasping means 101, and the estimated yarn arrival date and time grasping means 102. This is a weft supply duration measuring means that measures the time during which weft can be continuously supplied to each loom based on the scheduled arrival date and time of the weft.

Reference numeral 106 denotes a warp supply duration measuring means that measures the time during which warp threads can be continuously supplied to each loom based on the amount of remaining threads in the warp beam at the present time obtained by the loom in-process thread amount measuring means 100.

107 is a time period during which the loom stops waiting for weft supply, based on the date and time when weft supply cannot be continued, which is obtained from the weft supply duration measuring means 105, and the scheduled weft arrival date and time, which is obtained from the scheduled yarn arrival date and time grasping means 102. This is a weft waiting time measuring means for measuring the weft waiting time.

108 is the date and time when warp supply cannot be continued, which is obtained from the warp supply duration measuring means 106, and the warp beam creation date and time, which is obtained from the warp beam stock grasping means 103, the yarn stock grasping means 101, and the warp beam creation time grasping means 104. This is a warp waiting time measuring means for measuring the time during which the loom stops waiting for the warp to be supplied.

An urgency instruction 109 determines and instructs the urgency of each loom from the weft supply duration obtained from the weft supply duration measurement means 105 and the warp supply duration obtained from the warp supply duration measurement means 106. This is means A.

110 ascertains the weft supply duration time and the warp supply duration time for each loom, and based on this, the weft waiting time obtained by the weft waiting time measuring means 107;
Urgency level indicating means B determines and indicates the degree of urgency of each loom from the warp waiting time obtained from the warp waiting time measuring means 108.

Reference numeral 111 denotes an adjusting means for adjusting the urgency instructions issued from the urgency indicating means A109 and the urgency indicating means B110.

Reference numeral 112 denotes a brightness control means for controlling the light intensity of the lamps of each loom according to the degree of urgency adjusted by the adjustment means 111.

The loom operating rate improvement device of the present invention includes the above-mentioned loom in-process yarn amount measuring means 100, raw yarn stock grasping means 101, raw yarn arrival date and time grasping means 102, warp beam stock grasping means 103, and warp beam creation necessary means. Time grasping means 104, weft supply duration measuring means 105, warp supply duration measuring means 106, weft waiting time measuring means 107, warp waiting time measuring means 108, urgency indicating means A109, urgency indicating means B110, adjusting means 111 , brightness control means 1
12.

(Function) Therefore, the amount of remaining yarn of each of the warp and weft threads set in the loom is determined by the loom thread amount measuring means 1.
00, each loom of the loom is measured moment by moment, and on the other hand, the amount of yarn in stock, which is a raw material for textiles, is grasped for each loom by the yarn inventory grasping means 101. The information is input to the weft supply duration measuring means 105.

In addition, the yarn arrival date and time grasping means 102 includes:
The delivery date to the weaving process notified from the spinning process or the yarn processing process is stored, and the weaving process knows when the yarn will arrive from the spinning process or the yarn processing process, which is the previous process. The scheduled arrival date and time of the raw yarn and the amount of yarn are grasped for each loom of the loom where the raw yarn is scheduled to be used, and these are also input to the weft supply duration measuring means 105.

Then, the weft supply duration measuring means 105
The loom in-process yarn amount measuring means 1 inputted to this
The duration of weft supply is measured using the current amount of weft in progress according to 00, the weft inventory amount for each machine by the yarn inventory grasping means 101, and the scheduled arrival date and time of yarn according to the yarn scheduled arrival date and time grasping means 102. do.

On the other hand, regarding the warp, the warp supply duration is measured by the warp supply duration measuring means 106 using the remaining quantity of the warp beam at the present time obtained by the loom in-process thread quantity measuring means 100.

After the supply duration of both yarns is measured in this way, the waiting time of each yarn is then measured. That is, for the weft yarn, the date and time when it becomes impossible to continuously supply the weft yarn to the loom is determined from the weft yarn supply duration (the date and time when weft yarn supply cannot be continued), and this date and time is determined by the raw yarn arrival date and time grasping means 102. The amount of time the loom will stop due to lack of weft is determined by subtracting it from the scheduled arrival date and time of the yarn.

For one of the warps, first, the presence or absence of the warp beam is checked by the warp beam inventory grasping means 103, and if there is a warp beam to be set, the beam with no warp is removed from the loom, and the next warp beam is placed on the loom. The time required to set the warp is the warp waiting time. If there is no warp beam to be set for this, the time required to create the warp beam can be determined based on the arrival date and time of the warp to the weaving process obtained by the yarn inventory checking means 101 and the expected yarn arrival date and time checking means 102. By adding the time required to create the warp beam obtained from the means 104 (warp beam creation time), the date and time when the warp beam can be created is measured. In addition, the date and time when the currently installed warp beam will run out of warp threads is determined from the warp supply duration time measured by the warp supply duration measuring means 106, and this is subtracted from the warp beam creation time. The time the loom stops because there is no warp yarn is calculated as the warp waiting time.

When the supply duration and waiting time are measured for each of the warp and weft yarns as described above, control is performed to change the brightness of the thread breakage lamp of the loom based on these measurements. At this time, the warp and weft supply durations are input to the urgency indicating means A109, and the urgency indicating means A109 grasps the weft supply duration and warp supply duration for all looms, and determines the length of this time. Depending on the situation, an instruction is given to change the brightness of the thread breakage lamp on the loom. On the other hand, the waiting time of each warp and weft is input to the urgency indicating means B110, and the urgency indicating means B110 grasps the weft waiting time and the warp waiting time for all looms, and also the supply duration of the warp and weft. Based on this, instructions are given to change the brightness of the thread breakage lamp on the loom.

In this way, two urgency indicating means A109 and B
The urgency instructions outputted from the loom 110 are both input to the adjustment means 111, and the urgency instruction adjusted by the adjustment means 111 is given to the brightness control means 112, so that the urgency of the loom is clearly determined. It is controlled so that the loom receives the appropriate service.

In other words, by giving a difference in the degree of urgency of a loom that has a lot of yarn that is being loaded or can be loaded on the loom, and that of a loom that has little yarn left, a difference will inevitably occur in the frequency of thread cutting. On the smaller side, that is, on the loom with less yarn left and the lamp brightness lowered, the time spent on splicing is reduced, and as a result, the time spent on piecing is reduced on the loom with more yarn remaining and the lamp brightness is set higher. will be concentrated and the overall operating rate will be improved.

Moreover, since the degree of urgency is displayed by the difference in the brightness of the lamps, the person in charge of taking measures can easily understand the degree of urgency.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

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 C is a CPU.
(Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory),
A microcomputer consisting of an I/O port, etc., 4 is an auxiliary storage device such as a magnetic disk or magnetic tape, 5 is a brightness control device that controls the brightness of the yarn breakage lamp of the loom, and 6 monitors the operating status of all looms. The above-mentioned devices are connected through an interface circuit.

The auxiliary storage device 4 includes a yarn inventory file 4a that stores the amount of raw yarn in stock for textiles woven by looms for each warp and weft and for each loom, and a yarn inventory file 4a for storing the raw yarn inventory amount of textiles woven by looms and for each loom, and a spinning process or yarn processing that is a pre-process of the weaving process. A yarn arrival schedule file 4b that stores the scheduled date and time of yarn arrival from the process to the weaving process and its quantity for each warp and weft and for each loom.
, a warp beam inventory file 4c that stores the amount of warp beams in stock, and a warp beam creation time file 4d that stores the time required to create warp beams for each loom. That is, the yarn inventory file 4a is the yarn inventory grasping means 10.
1, the yarn arrival schedule file 4b serves as means 102 for grasping the expected yarn arrival date and time, the warp beam inventory file 4c serves as the warp beam inventory grasping means 103, and the warp beam creation time file 4d grasps the warp beam creation time. It is used as means 104.

Further, this auxiliary storage device 4 stores master tables A to D.

In master table A, for example, for looms classified by weft supply duration and warp supply duration in the format shown in Figure 3a, weaving machine emergencies are listed for each class in the format shown in Figure 3b. degree is registered. In the example shown in the same figure, it is shown that if the supply duration is 12 hours or more for both the warp and the weft, the class is A1.

Furthermore, in the master table B, classification of looms based on weft waiting time is registered in the format shown in Figure 4, for example, and on the other hand, classification of looms based on warp waiting time is registered in the format shown in Figure 5, for example. Classification is registered in master table C.

Then, on master table D, for example, the sixth
The master table A,
The brightness of the thread breakage lamp of the loom is registered for all combinations of the classes B and C, respectively. As can be seen from the example in the same figure, the brightness of the thread breakage lamp of the loom is different in classes where the warp supply duration is longer (for example, classes A2 and A3), and in classes where the weft waiting time is shorter (for example, classes B1, B2, and B3). ), and conversely, the weft supply duration is longer (for example, class A4, A
5, A6), the shorter the warp waiting time (for example, classes C1, C2, and C3), the higher the setting is registered. This is done in consideration of the fact that if either the warp or the weft cannot continue to be supplied first, the shorter the waiting time, the sooner the loom can resume operation. In the example shown in the figure, both the warp supply duration and the weft supply duration are 12 hours or more, and class A1
For those belonging to the loom with a weft waiting time of less than 0.5 hours, that is, class B1, those classified as classes C1 to C5 in terms of warp waiting time have a high brightness yarn breakage lamp, and those of C6 have a medium brightness. It is registered that.

The ROM of the microcomputer 3 mainly stores the following programs, including the loom in-process yarn amount measuring means 100, the weft supply duration measuring means 105, the warp supply duration measuring means 106, and the weft waiting time. They are used as a measuring means 107, the warp waiting time measuring means 108, the urgency indicating means A109, the urgency indicating means B110, and the adjusting means 111. That is, the contents of the master tables A, B, C, and D are
The input device 1 and the display device 2 are used to add, update, and delete programs, and the input device 1 and the display device 2 are used to create the yarn inventory file 4a, the yarn arrival schedule file 4b, and the warp beam inventory file 4c. , the warp beam creation time file 4d
The program for adding, updating, and deleting contents and the loom operating status monitoring device 6 determine, for each loom, the amount of warp on the warp beam attached to the loom, the amount of weft, and the date and time when the loom started operating and the date and time when the loom stopped. A program to import loom data such as time and time, data of this loom, data of the yarn inventory file 4a, data of the yarn arrival schedule file 4b, data of the warp beam inventory file 4c, and warp beam creation. A program that calculates the weft supply duration, warp supply duration, weft waiting time, and warp waiting time for each loom from the data of the required time file 4d, etc.; A program that calculates the urgency A for each loom from the master table A, a program that calculates the urgency B for each loom from the master tables B, C, and D, and a value between the urgency A and the urgency B. This is a program that adjusts the brightness and sends it to the brightness control device 5. However, these programs do not necessarily need to be stored in the ROM, but can be stored in the auxiliary storage device 4.
You may also load it into RAM and then execute it.

The brightness control device 5 receives a command from the microcomputer 3 and controls the voltage flowing to the thread breakage lamps of all the loom groups based on the designated degree of urgency.

Next, a specific example of the processing performed by the microcomputer 3 will be described with reference to flowcharts shown in FIGS. 3 to 5.

FIG. 7 is a flowchart of a program for determining the weft supply duration. In the step shown in the figure, the amount of weft yarn in stock for each loom is read from the raw yarn inventory file 4a and input into the microcomputer 3.

In the step, the amount of weft in progress of the loom is determined by the following formula (a) based on the data of the loom, such as the amount of raw yarn initially set and the time since the start of operation.

(Amount of weft in process) = (Amount of weft initially set) - (Amount of weft used per unit time) × (Loom operating time from the start of weft to the present)
In step (a), the weft supply duration is measured using the following equation (b).

(Weft yarn supply duration) = (Weft inventory amount) + (Current amount of weft in progress) / (Weft usage amount per unit time) ...(b) What is the weft usage amount per unit time in the above formula (b)? This is the rate at which the weft threads are consumed during normal operation of the loom, measured in kilograms per hour. In addition, the current amount of weft in progress is the amount of weft threads set in the loom, and the product of the elapsed time from the start of weft to the present time and the amount of weft used per unit time is calculated as the amount of weft thread at the time of start of weft. It is measured by subtracting it from the amount of work in progress.

In the step, the yarn arrival scheduled file 4 is
The scheduled yarn arrival date and time is read from b, and it is determined whether the weft supply to the loom will continue until the next scheduled yarn arrival date and time. When it is determined that the operation of the loom can be continued until the scheduled arrival date and time of the yarn, the process proceeds to step.

In the step, the yarn arrival scheduled file 4 is
The expected arrival amount of raw yarn is read from b, and the following formula (c) is added to the weft supply duration, and this value is set as the weft supply duration.

(Scheduled arrival amount of raw yarn) / (Amount of weft yarn used per unit time) ... (c) However, if it is determined in the above judgment that the operation of the loom cannot be continued, the value calculated in the step will be used to determine the continuous supply of weft yarn. It is considered as time.

In the step, it is checked whether there is a next yarn arrival schedule following the step by searching the yarn arrival schedule file, and if there is, the process returns to the step, and if not, the value obtained in the step is used as the weft supply duration. That is to say.

Next, a method for calculating the weft waiting time will be explained based on the flowchart of the program for calculating the weft waiting time shown in FIG.

First, in step, the date and time when weft supply cannot be continued is determined using the following equation (d).

(Date and time when weft supply cannot be continued) = (Current date and time) + (Weft supply duration) (d) Next, in the step, the scheduled arrival date and time of the yarn is read from the yarn arrival schedule file 4b.

Then, in the step, the above-mentioned date and time when weft supply cannot be continued is compared with the scheduled yarn arrival date and time, and if the scheduled yarn arrival date and time is earlier, return to the step and read the next scheduled yarn arrival date and time, and if it is later, The following formula
Calculate the weft waiting time using (e).

(Weft waiting time) = (Scheduled date and time of yarn arrival) - (Date and time when weft supply cannot be continued) ...(e) Next, the flowchart of the program for calculating the warp waiting time shown in Fig. 9 for the other warp. The explanation will be based on.

First, in step, the presence or absence of a warp beam is read from the warp beam inventory file 4c, and if there is a warp beam, the process advances to step, and if there is no warp beam, the process advances to step.

In the step, the warp waiting time is the time required to remove the beam with no warp threads, set the warp beam in stock on the loom, and restart the loom operation.

In the step, first, based on the data of the loom, the remaining yarn amount of the warp beam is determined by the following formula (f), and then using this, the warp supply duration is determined by the following formula (g).

(Amount of yarn remaining on the warp beam) = (Amount of yarn on the first warp beam set) - (Amount of warp used per unit time) × (Loom operating time from the start of work to the present)
...(f) (Warp supply duration) = (Remaining yarn amount of warp beam) / (Warp usage amount per unit time) ...(g) Next, using the warp supply duration found above, calculate the following: The date and time when warp supply cannot be continued is determined using formula (h).

(Date and time when warp supply cannot be continued) = (Current date and time) (Warp supply duration) ... (h) In step, the time required to create the warp beam is determined from the warp beam creation time file 4d.

In the step, the yarn inventory file 4a is searched to see if there is a warp needed to create a warp beam, and if there is, the process advances to the step; if not, the process advances to the step.

In the step, the time required to create the warp beam obtained in the step is added to the current date and time to calculate the warp beam creation date and time.

On the other hand, in the step, the expected date and time of yarn arrival is read from the yarn arrival schedule file, and the time required for creating the warp beam is added to this and the time is set as the warp beam creation date and time.

In this step, this warp beam creation date and time is compared with the date and time when the warp supply cannot be continued, which was found in the step, and if the date and time when the warp supply cannot be continued is later, the process returns to the step, and if it is earlier, the process proceeds to the step.

In the step, the warp waiting time is determined using the following equation (i).

(Warp waiting time) = (Warp beam creation date and time) - (Date and time when warp supply cannot be continued) + (Warp waiting time of step) ... (i) As described above, supply duration and waiting time for each warp and weft. Once these are measured, the degree of urgency for each loom is calculated based on these. That is, the urgency level A is determined by classifying the warp and weft supply durations into classes as shown in FIG. Use what you find by reading.

On the other hand, for urgency level B, the weft waiting time is classified into classes as shown in Table 3 of the master table B mentioned above, and the warp waiting time is classified into classes as shown in FIG. 5 of the master table C mentioned above. From master table D, all combinations of each class classified in master tables A, B, and C are created, and the urgency of the loom is given for each combination as shown in FIG. 6, for example. Use the one determined by reading the degree of urgency of the loom.

Finally, the urgency level A and the urgency level B obtained in this way are adjusted, one of the values is adopted, and this is input to the brightness control device 5, which is used for monitoring the loom operating status. When all the data from the loom by the device 6 is normally sent from the microcomputer, the value of the urgency level B is adopted, and when some data from the loom is missing and the weft waiting time cannot be calculated, Or, if the warp waiting time cannot be calculated, the urgency level A
This is done by using the value of , and instructing the brightness control device 5 to control the brightness of the lamp of the loom.

(Effects of the Invention) As described above, the loom operation rate improvement device of the present invention grasps the supply status of raw yarn to the loom, and increases the number of warps and wefts that are being loaded or can be loaded into the loom. While increasing the level of urgency to increase the productivity of the loom, the level of urgency for looms where the supply of warp and weft yarns to the loom will soon be cut off is lowered to reduce the amount of warp and weft yarn used by the loom per unit time. By reducing this, it is possible to extend the continuous supply of warp and weft yarns to the loom until the new warp and weft yarns arrive at the weaving process, making it possible to improve the operating efficiency of the entire loom group. be. In other words, there is no need to increase the urgency of a loom that will soon be unable to supply warp or weft yarns, considering that the loom will be stopped waiting for yarn, and by reducing this, the frequency of yarn cutting in this loom can be reduced. This reduces the time that the stand holder spends on thread splicing work.
As a result, the stand holder can increase the time consumed for splicing on a loom where both the warp and the weft are supplied to the loom for a long time. As a result, wasted stop time and work time are eliminated, and the operating rate of the entire loom group is significantly improved.
