Description

The present invention relates to a quality production control system in a spinning factory.

[Prior Art] Generally, in a spinning factory, yarn is produced through various processes such as receiving raw cotton, blended cotton, carding, kneading, roving, rewinding, inspecting packing, and shipping to warehouse. Post-process,
For example, it is handed over to the process of weaving and dyeing.

FIG. 12 shows an outline of a system configuration of processes from a spinning machine to a warehouse in a conventional spinning factory.

The left side of the figure is configured as a so-called fine spinning winder in which a large number of fine spinning machines 1 and winders 2 are directly connected, and the fine spinning bobbins 3 produced by the fine spinning machine 1 are doffed all at once, and along the fine spinning spindle. The bobbin tray 4 capable of pitch movement is inserted. Then, the bobbin 3 is sent to the winder 2 while being integrally attached to the tray 4, and is rewound on the winding package 5 having a predetermined shape and a predetermined amount of yarn. The package 5 fried from the winder 2 is the overhead conveyor 7, the unloading device 8
And the package transfer system 6 including the unloading device 9 supplies the inspection station 10.

At the package inspection station 10, the yarn layer surface state of the package is checked by the operator's visual inspection or an optical inspection device, the defective package is removed from the transfer line, and the good package is stored in the stocker 14 and the packing 18 Then, the label 16 is applied and the product is stored in the warehouse 19.

[Problems to be Solved by the Invention] However, in the past, when an abnormality relating to production or quality occurs at the inspection station or the like in a spinning factory, or after the product is shipped, a post-process such as woven fabric or dyeing is performed. If a quality-related problem occurs in the product,
It was not possible to identify the number of spinning machines or winders and the weight of the products produced. Therefore, it is extremely difficult to understand "when, where, and what kind of problem has occurred" when making a countermeasure.

The history of individual products cannot be traced back to the machine frame and weight of the spinning machine or winder as described above for the following reasons.

One spinning machine or one winder consists of multiple units (weights), and it is unknown which machine the product passed through.

There is no means for identifying which bobbin of the spinning machine and bobbin of the spindle were supplied to which bobbin of the automatic winder.

There is no way to identify the number of the automatic winder and the weight of the winding package packed in which box.

The object of the present invention is to identify the manufacturer from the history when a problem related to production or quality occurs in a spinning factory, or when a problem related to quality occurs in a post-process such as woven fabric or dyeing after shipping a product. The purpose is to provide a production management system for a spinning factory that can grasp the situation and take countermeasures.

[Means for Solving the Problems] In the production management system of the present invention, the bobbin on the spinning machine is inserted into a bobbin tray and sent to a winder, and the doffed package is unloaded from the winder onto a hanger, and the hanger conveys the package. In a spinning factory that unloads the hangers, inserts them into the package tray, supplies them to the inspection station, and packs the good packages into boxes, install recording media on the bobbin tray, hangers, and package trays. And a writing device for recording the weight number (manufacturer information) on the recording medium of the hanger, a reading device and a writing device for transferring the recording information from the recording medium of the hanger to the recording medium of the package tray when unloading, Provided with visible display means for reading transcription information from the package tray and adding manufacturer information to the package It is a thing.

[Operation] The machine number and the weight number, which are the bobbin manufacturer information, are written and managed on the recording medium of the bobbin tray between the spinning machine and the winder. In addition, the machine number and the weight number, which are the manufacturer information of the package, are written and managed on the recording medium of the hanger during the unloading and unloading of the hanger.
At the inspection station, it is written and managed on the recording medium of the package tray, and even when it is removed from the package tray before being packaged, the above-mentioned manufacturer information is attached to the removed package by visual display means such as labeling. It is attached and managed. In addition, for the sake of simplicity, the management may be performed by visually displaying the winder machine stand numbers supplied in the packaging case containing a plurality of packages.

Therefore, the product flow and the flow of information in the spindle unit of the spinning machine or the winder are synchronized in the process of rewinding the bobbin from the spinning frame into the package and entering the warehouse. Detailed information can be managed by computer, history can be grasped, and even if a poor quality product is found from the visually displayed manufacturer information, the cause can be traced back to the process, machine base and weight. it can.

[Example] Hereinafter, the present invention will be described with reference to an illustrated example.

FIG. 1 shows an outline of a system configuration of processes from a spinning machine to a warehouse in a spinning factory.

In the figure, 1 is a spinning machine, 2 is a winder, and a plurality of machines, 40 machines in this case, are installed respectively, and the spinning machine 1 and the winder 2 are directly connected to each other to form a so-called spinning winder 2. I am configuring. Each of the machine frame of the spinning machine 1 and the winder 2 is formed by arranging many units in parallel.
A fixed length device 35 is provided on each machine stand.

The spinning bobbins 3 produced by the spinning machine 1 are doffed all at once and placed on a tray 4 capable of pitch movement along a spinning spindle. Then, the bobbin 3 moves intermittently based on the bobbin request command from the winder 2 side, and is conveyed in the arrow direction toward the winder 2 side while being integrally attached to the tray 4. The yarn of the bobbin 3 is rewound by the winder 2 into a winding package having a predetermined shape and amount, and the full winding package 5
Is fried from winder 2 and is an overhead conveyor
It is supplied to the inspection station 10 by the package transfer system 6 including the unloading device 8 and the unloading device 9.

At the package inspection station 10, the thread layer surface condition of the package is checked by the operator's visual inspection or an optical inspection device, defective packages are removed from the conveyance line, and good packages are sorted by product type and stored in the stocker. Be stored. After that, the selected individual packages are labeled as visual display means16,
After going through the steps of automatic vinyl packing 17 and automatic box packing 18, they are packed and stored in a warehouse 19.

(1) Spinning Winder First, the spinning winder will be described with reference to FIG.

Outline In Fig. 2, the spinning bobbins produced by the spinning machine 1 are doffed all at once and the pitch can be moved along the spinning spindle. Inserted on the provided peg. Then, based on the bobbin request command on the winder 2 side, the transport band 23R or 23L intermittently moves in the direction of the arrow 24, and the bobbin is transferred via the inclined connecting conveyor 25R or 25L, and the conveyor 25R or 25L Chute 26R or 26 from top
It drops into L and is mounted on the tray 4 waiting at the bobbin supply position 27.

The tray integrated with the bobbin is supplied to the yarn end preparation device 28, the yarn end is exposed in a state suitable for yarn splicing in the winder, and is conveyed on the conveying path 29 toward the winder 2 in the direction of the arrow. To be done.

On the winder side, the bobbin is supplied to each winding unit while being attached to the tray, and is rewound and discharged. The empty bobbins and the like discharged from each winding unit to the transport path 30 are transferred to the bobbin removing station 31 while remaining integrated with the tray, and at the station 31, those having an empty bobbin and residual yarn are transferred to the winder. A bobbin with an extremely small amount of remaining thread that cannot be re-supplied is taken out from the tray on which the bobbin is inserted, and the empty bobbin is returned to a predetermined position on the spinning machine 1 side via an empty bobbin transport path (not shown), and the extremely small amount of residual thread remains. The threaded bobbin is separately discharged or stored in the box. Therefore, the tray that has passed through the bobbin removing station 31 is only the empty tray or the tray having the bobbin with the residual thread that can be re-supplied to the winder.

Each time an empty tray arrives at the spinning bobbin supply position 27, the transport band 23 or 23L on the spinning machine side is rotated by one pitch and one spinning bobbin is supplied and inserted on the empty tray on standby. , Again supplied to the wine dig unit.

Conveyance tray Between the spinning machine and the winder, the yarn produced by one spinning machine unit is inferior in quality to the yarn produced by another unit, and the phenomenon of frequent yarn breakage in the rewinding process occurs. However, it may be confusing to understand the situation where there are many yarn splicing points in the wound package on the winder side. That is, the yarn produced by the specific spinning unit is free to be rewound in which winding unit in the winder, and therefore, from a spinning unit that produces a yarn of poor quality due to some cause. Since the doffed bobbin and the bobbin doffed from another normal spinning unit are supplied to the winder in a random state, poor quality yarn is mixed in many doffed packages in the winder. Sometimes.

Therefore, by tracking the transport route of the yarn produced by the spinning unit, the spinning unit that is the manufacturer of the bobbin, where the yarn breaks abnormally frequently during rewinding in the winder, is grasped, and the yarn break information on the winder is collected. A transport tray that can feed back to the spinning machine and manage each spinning unit of the spinning machine is required.

For such a purpose, an identification display member (recording medium) capable of writing and erasing the identification information of the bobbin is attached to the bobbin transport tray that individually independently supports and transports the spinning bobbin.

That is, the tray 4 shown in FIGS. 3 and 4 has a disc-shaped base 42.
A peg 3 for bobbin insertion is formed on the bobbin, which is integrally formed of a non-conductive member such as synthetic resin. Although the air passage hole 44 is formed inside the tray 4, it may be solid.

An annular groove 45 is formed on the upper surface of the disc-shaped substrate 42 of the tray 4.
An iron plate 46 for strengthening the magnetization is fixed in the groove, and a recording medium made of a rubber magnet sheet 47 is fixed on the iron plate 46. Ferrite powder is contained in the rubber magnet sheet 47, and any magnetization is performed by bringing the magnets close to each other.

In FIG. 3, a magnetized portion 48 is formed as a start signal for writing or reading of information at one location on the circumference of the tray with radius r1 and information is written at equal pitches on the circumference of radius r2. Magnetized portions 49a to 49m are formed in advance as block signals indicating the writing position or the reading position.

Further, on the circumference of radius r3 is formed a magnetizable portion 50 in which the identification information of the spinning bobbin is written. First,
In the embodiment shown in the second drawing, the identification information writing portion is made up of four sensations, and information indicating the R side and L side of the spinning machine described later is written in the portion 50a corresponding to the clock 49a, and the other three sections S1. In S2 and S3, the "machine number and weight number" of the spinning machine in which the bobbin inserted into the tray is produced are written.

As a writing head (writing device) 32, as shown in FIG. 4, two magnetic sensors 36 and 37 and a writing electromagnet 38 are provided in the radial direction of the tray, and as a reading head (reading device) 33, As shown in FIG. 5, three magnetic sensors 39, 40, 41 are arranged in the radial direction of the tray, and such heads 32, 33 have rubber magnets 47 on the upper surface of the tray at the writing position and the reading position of the tray. It is moved or fixedly installed with a space of a distance a from the surface. The dimension a is 1.
5mm is suitable. That is, the magnetic sensors 36 and 39 read the start signal 8 on the tray, and the magnetic sensors 37 and 40.
Is for reading clock signals 49a to 49m, magnetic sensor 41
Is for reading the identification information of the bobbin.

Management of Machine Number and Weight Number Next, in the spinning winder shown in FIG.
Bobbin tracking when the tray 4 of FIG. 4 is applied will be described.

When the tray 4 is applied, as shown in FIG. 2, a write head 32 for writing the identification information of the spinning bobbin inserted on the tray is installed in the entrance side transport path 29 of the winder 9, and the winder is installed. A read head 33 for reading the above information is installed on the delivery path 30 on the output side. Above head 3
The operation commands of 2, 33 are issued by the controller 34. Further, on the winder side, a fixed length device 35, which is a control device with a built-in computer for inputting various information of the winding unit and information from the reading head, is installed.

Further, in the winder 2, the yarn breakage detection feeler provided in each winding unit detects the yarn breakage and inputs it to the constant length device 35, and at the same time, the number of yarn breakages of the bobbin being rewound in each unit is added and stored. To be done. In addition, the winding unit has a fixed length device when the number of thread breaks exceeds a set number during winding of one bobbin.
There is a lamp that blinks according to the signal from 35.

In FIG. 2, the spinning machine 1 is for all spinning machines,
An identification number identifying the weight is given.

Now, when the doffing on the spinning machine, that is, when the full bobbin spinning bobbin and the empty bobbin are exchanged, the spinning bobbins RB1, RB2, ... RBn are placed on the transport band 23R on the front side of the spinning machine, and the other side is placed. Spinning bobbins RB1, RB2,… R on the transport band 23L
Bn is placed.

Under the above condition, a bobbin request signal is issued from the bobbin supply station 27 on the winder side to the spinning machine side. First, the bobbins RB1 at the head of the R-side transport band 23R are sequentially supplied to the empty trays on standby. At this time, each time a bobbin is supplied from the spinning machine, the weight numbers RB1 to RBn of the bobbins supplied to the tray by the writing device 32 and the machine frame number of the spinning machine are written. That is, at the writing position, the tray 4 is rotated at a constant speed in the direction of arrow 51 in FIG.
If L is magnetized on the R side, for example, if the bobbin RB1, the R / L identification portion 50a in FIG. 3 is magnetized, and the identification code corresponding to the first weight is added to the section S1. Be magnetized. For example, in the case of Unit 3, Unit 001,
"03001" is added as shown.

Then, the transport band moved 1 pitch,
When the bobbin of the second spinning machine is supplied onto the tray 4, the magnetized state "03002" corresponding to the weight number 2 is written on the tray 4, as shown in FIG. In this way, every time the bobbin is supplied, the weight number plus 1 is encoded and written in the tray.

The spinning bobbin 3 is supported on the tray in which the machine number and the weight number are written as described above, and the spinning bobbin 3 is transferred in the arrow direction on the conveying path 29 via the yarn end preparing device 28 of FIG. It is supplied to the winding unit. A winder disclosed in, for example, Japanese Patent Laid-Open No. 57-170354 can be applied as a winder for supplying the bobbin to the rewinding position while being attached to the tray.

When one bobbin is supplied to the rewinding position and the rewinding operation is started, the number of times of notting is added in the constant length device 35, and the number of times of notching per unit time (minute) of the bobbin exceeds the set value. Assuming that the spinning bobbin has too many yarn defects, a winding stop command is output to the unit and the lamp of the unit is blinked to notify the operator.

When the operator removes the bobbin in the middle of rewinding at the rewinding position of the blinking lamp winding unit from the tray and performs the re-start operation, the empty tray is dispensed from the unit onto the transport path 30 in FIG.
It is transported in the direction of the arrow.

When the empty tray that does not support the bobbin reaches the position of the read head 33, the identification information on the empty tray is read, the weight number is read, and it is transferred to the fixed length device 35 as shown in FIG. The transferred data is sent to the fixed length device 35 or each fixed length device.
Totaled by the computer (Monitron) that controls 35,
It is possible to know the defective spindle number of the spinning machine and the machine number to which it belongs.

At this read head position, of course, like the write position, the tray is rotated once for reading, but the tray and the write or read head may be rotated relative to each other, so that the tray is fixed in position and the head is fixed. It is also possible to rotate once.

The empty tray that has passed through the reading device 33 is transferred to the bobbin supplying position 27, and again receives a new spinning bobbin,
The machine number and the weight number of the spinning machine that produced the bobbin are newly written, and the machine number and the weight number previously written are erased.

The fixed length device 35 also collects and manages the following quality information. Operating efficiency, take-up yarn length, number of yarn splicing trials,
BQC (Bobbi) for monitoring the number of successful thread splices, the number of yellow button protrusions that project when multiple consecutive splices are unsuccessful, and an abnormally high number of thread breaks per bobbin.
n Quality Check) The number of occurrences, the thickness of which is abnormally thick and thin, the defect of which the yarn thickness is abnormally thick and long, the clearer cut which occurs when the yarn thickness is abnormally thin and long, above Collection of defective spindle numbers of spinning machines and machine numbers to which they belong.

In addition, in the case of a computer (MONITRON) that supervises each fixed length device 35, in addition to the centralized monitoring for each of the fixed length devices 35 to, the cause analysis of the thread breakage and the cause analysis of the yellow button are performed. , Factor analysis of the decrease in operation efficiency, and measurement data collection of splicer checker (automatic measuring machine for yarn strength at yarn splicing part).

In the above embodiment, the fine spindle number is written on the rubber magnet sheet fixed to the tray to explain the management system of the fine spinning machine. However, information for identifying the type of bobbin inserted into the rubber magnet sheet is written. It is also possible.

As described with reference to FIGS. 3 to 6 above, the bobbin transport tray 4 is provided with a writable and erasable identification information display member, and if the identification information of the bobbin to be inserted is written, the tray itself will display the identification information. Since the transfer is carried out integrally with the bobbin, the bobbin can be traced more easily than in the case where the tray has an identification mark unique to the tray.
