Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a machine management system for an automated spinning vX machine, and in particular, it analyzes Inuyama data obtained from a management device by a computer rather than by a human. This is related to the rationalization of machine management by making decisions.

[Prior Art] In the spinning process, innovative spinning machines - oven-end machines and air jet machines - have been developed, and labor-saving, rationalization and speeding-up have been achieved, resulting in high productivity. Furthermore, with the recent development and lower prices of computers, the management devices of spinning machines have become more sophisticated, and it has become possible to easily obtain various data from these devices.

However, while the spinning vj machine itself is being automated, humans are still responsible for organizing and analyzing the Oita data obtained using management devices, and the various management devices are distributed and their processing is also done separately,
Currently, the work of maintaining a single quality control machine cannot be automated. This is because organizing and analyzing data requires sophisticated judgment based on experience.

[Problems to be solved by the invention] As mentioned above, in the past, it was a skilled person who organized and analyzed the data on large seedlings obtained from a spinning machine, and humans had to analyze and judge the data collected by the device. As a result, it was difficult to perform quality control maintenance work on the two machines, and appropriate measures could not be taken, especially with unfamiliar work tools.

That is, how to organize and analyze this data and how to communicate it to workers have become important issues.

Therefore, an object of the present invention is to go a step further and solve the above-mentioned conventional problems by having a computer, rather than a human being, analyze and judge the data collected by the device and instruct the operator. Easy yarn quality control and maintenance work.
To provide a spinning machine management system that is efficient and can be implemented by anyone.

[Means for Solving the Problems] The spinning machine stand management system of the present invention is capable of managing the sliver supplied to each spindle, the parts constituting each spindle, and the production of each spindle in a spinning machine having a plurality of spindles. A management device that generates production management data such as status, a means for classifying and storing data obtained from the management device into one item per weight, and a means for storing data for each item and setting values set for each item as a weight. Compare each time sequentially,
A means for finding the weight or the parts that make up the weight that are the source of data that exceeds the set value, and when the weight or the parts that make up the weight are found, specific yarn quality that corresponds to them. It is equipped with a means for reporting the contents of management or maintenance work.

Here, the specific yarn quality control or maintenance work content refers to replacement of slivers and parts, checking of parts, etc.

[Function] For example, if a weight includes a part that requires maintenance work such as replacement, the production control data for that part generated by the management device will be larger than its set value. Therefore, the part and the weight having the part are found by the searching means. Then, the notification means notifies the worker of the plow and parts, and also instructs the worker to replace the parts. In this case, workers can use raw, detailed production control data that requires analysis without making judgments.
All you have to do is work based on the final instruction result of exchange.

[Example] An example of the present invention will be described below based on FIGS. 1 to 7. In this embodiment, this system is applied to an air spinning machine, but the present invention is not limited to this.

FIG. 1 shows an example of a machine management system for a spinning machine according to the present invention.

Factory A1. : There are multiple spinning racks installed on the machine stand (N01
... NQ n ) weights, and each weight has a yarn clearer 1.
Super Spectron 2. C, 1, A.

3 are installed separately. Additionally, the machine is equipped with a Dotsufa Knock 4 that is commonly used for each spindle.

Here, the yarn clearer 1 has the functions of removing slabs, reporting end-down, and making the width of the fully wound thread constant (fixed length), and outputs a yarn unevenness signal and a yarn running signal.

The Super Spectron 2 uses the yarn unevenness signal and yarn running signal from the yarn clearer 1 to manage yarn quality during production, and at the same time manages the top roller, bottom roller, and sliver. Publication No.).

C, 1, A, and 3 manage the production status of each spindle by using a yarn running signal and a red flag status signal to be described later, and at the same time manage knocks, dots, and slivers.
4481 specification).

Dotsufa Knock 4 consists of a dotufa that automatically replaces a full bobbin with an empty bobbin, and a knock that is placed on a trolley that runs on the machine platform and automatically performs thread splicing work. .

The above-mentioned distributed control devices 1, 2, and 3.4 are connected via serial lines and connected via a modem 5 to a host computer 6 in the central control station B, where each production control data is collected in bulk and processed as described below. perform an analysis to For this collection 1 analysis, a simple and inexpensive hand belt computer 7
It is also possible to use the data or analysis results collected from each spindle using the method (Japanese Patent Application Laid-Open No. 132644/1983).

Instructions to the worker based on the analysis results by the host computer 6 are displayed on the display of the display computer 8 and the display 9 near the machine. In addition, C above the palace
,1,A,3. It is also possible to check the display on Super Spectron 2.

Furthermore, here, F is used as a means of notifying (instructing) workers.
It uses audio using M waves. That is, the message generator 10 that receives the signal from the display computer 8 generates a message when maintenance work is required, and transmits the message to the FM.
A transmitter 11 transmits the message to a worker wearing headphones 12 by voice.

When maintenance work is not required, the computer 8 automatically plays music from the audio cassette 13.

By the way, if a problem with yarn quality occurs in the spindle of the spinning pen, the host computer 6 automatically stops the spindle. Then, from the data, we understand the phenomena as shown in the table below,
The host computer 6 automatically performs cause analysis and instructs the worker on specific work contents. Additionally, if the operating efficiency decreases, the system also instructs how to deal with it.

<Table> Analysis Elements Here, in order to understand the explanation of the above table, a schematic explanation of the parts related to maintenance management of air spinning will be given using FIG. 2. 20 is a spinning machine, and a drawing device 21 for the sliver S is provided on the upper part of the spinning machine. Air injection nozzle 22. It has M number of weights (units) 14 each consisting of a spinning device including a nip roller 23 and the like, and a winding device 24 provided at the lower front of the machine stand 20 and winding the yarn spun by the spinning device.

The stretching device 21 includes a back row 515. Apron 16
The front roller 19 includes a top roller 17 and a bottom roller 18. Top roller 1
There is a rubber part called Totsubukotsu on the outer periphery of 7, which can be replaced if it wears out. Inside the machine base 20, there is a knock unit 28 that moves along the plurality of units of the winding device 24 in the longitudinal direction of the machine base by guide rails 25 and 26.
is provided.

29 is a yarn clearer, 30 is a lever that is turned on when the slab breaks, and a knock unit detects this lever 30 and stops it. Also, 31 is a fault signal display board (red lever) called a red flag, which indicates a cause other than slab breakage (tension breakage).

If thread breakage (natural thread breakage or end down) occurs due to nozzle clogging, slab in the can disappearing, etc., and automatic thread splicing is not possible with the knock single 28,
In response to the red flag status signal, the red lever 31 protrudes from the front of the machine base cover 32 to notify the operator. The relationship between the lever 30 and the red lever 31 is as follows. The lever 30 is turned on when slab breakage occurs and stops the knock unit 28.

The red lever 31 is turned ON when the thread naturally breaks, and the knock unit is passed through without stopping, and the red lever 31 is ONL due to the thread tying operation by the knock unit, and this state is maintained when the thread splicing fails. In the case of slab breakage, the cutter actively cuts the thread based on the slab signal, so the slab breakage is determined based on the slab signal and the no thread signal due to thread breakage, and in the case of end-down, the end-down occurs without a slab signal being output. , only the thread breakage signal is output and it is determined that the end is down (Japanese Patent Laid-Open No. 57-1413
(See Publication No. 65). 33 is a full volume indicator lamp (LED)
This LED 33 is provided on both the front and back surfaces of the machine cover 32, with the front LED for the operator and the rear LED for the operator.
ED is for trolleys.

Note that each of the phenomena listed in items 1 to 11 in the table is detected by the corresponding detector, and specific instructions for maintenance work corresponding to each phenomenon are written in the display column. The maintenance work will be performed by the worker, tie-up worker, etc. specified in the designated field. Here, a worker is a stand holder, and is a person who patrols and checks the machine like a factory worker, and performs tasks such as supporting cans, processing end-downs, replacing full packages, etc., and is responsible for maintenance. A worker is someone who can repair complex machinery.

In addition, item 11 is that if a problem that cannot be analyzed occurs in this system, for example, the power spectrum data of yarn unevenness at the time the problem occurs is displayed to assist the work manager (supervisor) in the analysis work. means.

A host computer 6 for executing the table contents described above.
The maintenance diagnosis based on C,
It is divided into 1, A, and data-based. Examples of these are as follows.

Figure 3 shows an overview of maintenance diagnosis using super spectron data. That is, first, it is determined whether the top roller 17 is defective or not, and if it is defective, it is assumed that the top roller is worn and a command to replace the top roller is output to the display computer 8. Proceed to step. In the next step, it is determined whether the bottom roller 18 is defective or not, and if it is defective, it is determined that there is a problem with the bottom roller and a bottom roller replacement command is output. Let's move on to the decision.

If there is any other defect, the spectrum data is checked as described above, and then the process proceeds to the final judgment step. In this step, it is determined whether the integral value (SD) representing the thickness of the thread is defective or not, and if it is defective, it is determined that there is a problem and a command to replace the sliver is output.
It merges with the negative time and moves on to another cycle.

FIG. 4 shows an overview of maintenance diagnosis using C, 1, A, data. First, it is determined whether the slab cut rate is large or not, and if not, it is subsequently determined whether the end down is large or not. When the slab cutting rate is large, it merges with the case when the slab cutting rate is large, and it is assumed that there is a problem with the sliver, and a sliver replacement command is output and the cycle ends.
If not, it is determined whether the number of knots is the minimum number of knots. If the number of knots is the minimum, it is assumed that there is no abnormality and the cycle ends, but if not, it is further determined whether the knot miss rate is large. If it is large, it is assumed that there is a knock problem and a knock check command is output and the cycle ends. If not, it is determined whether 5TRED (described later) is large or not, and if it is large, a red flag state long-term stop command is issued. After that, the cycle is completed by joining with the "no" time.

As mentioned above, in this system, the analysis of numerical data such as production information (efficiency, production, thread trimming rate) is not outsourced to a complainant, but the analysis is performed by a computer. The display format created by the display computer 8 based on the analysis is as shown in FIG. 5, for example. The 17th Nα23 unit has been out of service for a long time due to red flags on the upper stage.
This indicates that it is the 15th Nα39 unit. The words in parentheses mean that units whose 5TRED value is greater than or equal to 15 minutes/time are searched. That is, this is the set value that is the basis for determining whether the above-mentioned 5TRED is large or not, and this set value is determined based on experience or advanced technical judgment. The middle row shows the sliver exchange of the 46th unit N028 and its failure (DOWN) setting value is 3 times/hour or more, and the bottom row shows the sliver replacement of the 46th unit N028.
Knock check of α45 unit, 38th Nα10 unit and knock miss (MISS) setting value is 30%
It means more than that.

Further, when an unanalyzable problem occurs, detailed production information as shown in FIG. 6 is displayed in addition to the power spectrum data of yarn unevenness shown in FIG. 7. The meanings of the main terms used here are as follows.

MC is the machine Nα, SP is the unit N01EFF (%) is the efficiency, and STRED (win/lime) is the average waiting time for the worker to reset the red i.

Note that FIG. 5 and FIG. 6 correspond.

According to the above-mentioned embodiment, since a computer is used for quality control and maintenance work, quality control of yarn during production and analysis of maintenance work can be done automatically without the need for human labor. Reliability can be improved.Also, since the results are reported to workers as specific instructions for maintenance work, even workers who are unfamiliar with air spinning machines can maintain them at the best condesimin. .especially,
As a means of reporting to workers, we adopted audio using FM waves and played music when instructions for maintenance work were not required, so workers could hear the above information no matter where they were as long as they were within hearing range. Can receive instructions. Sound not only improves work efficiency, but is also effective for ergonomics (soundproofing, mental stability).

Additionally, multiple distributed management devices are connected via serial lines, and data is collected from the factory to the central control room all at once, making it easier to upgrade the system.

[Effect of the invention 1] In short, according to the present invention, instead of outsourcing the analysis of production control data to humans, it is done by a computer, and specific maintenance work is directly instructed to workers. It has an excellent effect in that quality control and maintenance work can be performed easily and efficiently by anyone.
