Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for managing warp defects in a warp warping process.

The general warp warping method involves first winding the warp yarn onto a sectional beam using a warper or partial sizing machine, then collecting several sectional beams together, and then winding them back onto the loom beam using an unwinding machine to obtain the required number of sectional beams. I'm trying to get the warp. If defects in the yarn, such as yarn breakage or fraying, occur during this winding process, these defects will appear again during operation of the rewinding machine. Therefore, defects caught in the sectional beam are usually corrected during the rewinding process. This correction work can be done by having the operator visually monitor the warp threads for missing or broken threads while the rewinding machine is operating, or by having the colored paper inserted into the defective area reappear during the winding process of the sectional beam. This is done by confirming that the material is being unloaded from the sectional beam and then stopping the operation of the rewinding machine.

However, normally, in the rewinding process, the number of sectional beams is at least three or four, and when there are many, warp threads from as many as ten sectional beams are combined to create a beam for one loom.

At this time, since the number of threads is large and their density is high, it is difficult to find defects. Furthermore, even if a yarn breakage detector or fuzz detector, which has been put into practical use with warpers and partial warpers, is used, accurate detection is difficult, and it has not yet been put to practical use.

Under these circumstances, detection of defects in the warp threads relies mostly on the operator's monitoring, which can easily be overlooked. If defective points such as thread breaks are overlooked during the rewinding process, other normal warp threads may break, creating a warp beam with many broken threads and splices, which significantly reduces weaving efficiency. result. Therefore, if all defects found in the process of winding a sectional beam are completely repaired using a rewinding machine, a higher quality weaving beam can be completed and the weaving operation rate will be significantly improved. .

Therefore, an object of the present invention is to process and store information such as the type and location of defects in warp yarns during the process of winding a yarn sheet onto a sectional beam, and to provide the stored contents to the rewinding process. To provide a management device that issues a warning to a worker and automatically decelerates or stops a machine before a defective point appears during operation, and allows repair work to proceed quickly and accurately.

Based on the above object, the present invention detects defects in the warp yarns by a yarn breakage detector or a fray detector, or by an operator in the process of winding the warp yarns onto a sectional beam, that is, on a warper or partial sizing machine. and generates a signal corresponding to the type of defect and the position of the warp threads,
This signal is encoded and stored. The position of the warp yarns is expressed using the winding length from the winding start of the sectional beam to the defective point or the cumulative amount of rotation from the winding start.

On the other hand, in the rewinding process, this sectional beam
When the tape is rewound, the winding start position is the same as the winding end position when it was previously wound with a warper or the like. Therefore, since the previously stored defect position signal is the position from the start of winding the sectional beam, that is, the position from the innermost layer, it must be converted to the position from the end of winding, that is, the position from the outermost layer. It does not correspond to the position from the start of winding in the rewinding process. The position of the defective part from the beginning of winding in the rewinding process is the difference obtained by subtracting the position of the defective part from the position of the end of winding of the sectional beam.

Therefore, at the end of winding the sectional beam, for example, the signal obtained by removing the beam and the resetting of the length measurement counter! - The end position of the winding, that is, the total winding length or the total cumulative amount of rotation, is known from the signal, and this signal and the position signal of each memorized defective location, that is, the winding length or cumulative amount of rotation from the beginning of winding to the defective location, are combined with this signal. Calculate the difference, convert it into a signal of the position from the start of winding in the rewinding process, and store it as a signal of the defect position in the rewinding process, or simply store the signal of the position of the end of winding of the sectional beam, and use it at any time. This allows it to be converted into a position signal on the rewinding process.

The signals of the type of defect and the position of the defect obtained in this manner are sent to a signal transmission means such as wired or wireless, a magnetic recording card, sheet 1-1, magnetic tape, etc., or a photoresponsive storage medium before the rewinding process. is transmitted to the rewinding machine using

On the rewinding machine side, the winding length or cumulative amount of rotation is measured, and the signal is compared with the transmitted signal at the position on the rewinding process, and the winding machine side measures the winding length or the cumulative amount of rotation, and compares the signal with the transmitted signal at the position on the rewinding process, and detects the position near where a defective point appears in the warp of each sectional beam, for example. An alarm is issued 10 meters before the defective point, the machine is decelerated, or the rewinding process is temporarily stopped when the defective point reaches an appropriate position. Such alarm, deceleration operation, and stoppage measures can be selected depending on the type of defect. For example, if there is a thread breakage, an alarm is issued and the machine is stopped, and if there is a large number of broken threads, an alarm is issued and the machine is decelerated, and once the breakage has passed, the machine starts to operate at increased speed again.

However, it is not always necessary to memorize the type of defective point; for example, if it is sufficient to memorize only the position of the yarn breakage and stop the rewinding machine, it is practically effective to use only a signal for the position of the defective point. .

In addition, if you print out a list of the locations of defects from the start of the rewinding process to inform the workers of the rewinding process, repair work can be predicted in advance and management can be done more smoothly and accurately. Work will be done.

Hereinafter, the structure and operation of the present invention will be specifically explained based on an embodiment shown in the drawings.

First, FIG. 1 shows a management device 30 of the present invention,
The upper part of the drawing is bordered by a dashed line, and the upper part shows the recording device 31 on the warper or Cat part glue machine side, and the lower part shows the reproducing device 32 on the rewinding machine side. .

First, a large number of warp yarns or yarn sheets 1 of a warper or a partial sizing machine are guided by a guide roll 2 and wound around a sectional beam 3. Since the pulse cam 4 is connected to the guide 1-2, the pulse generator 5
A pulse signal is generated for each medium length and sent to the pulse counter 6. Here, the pulse counter 6 is
The pulse signals are integrated to indirectly measure the winding length of the yarn sheet 1 on the sectional beam 3, and output as a calculation signal to a computer 7 such as a CPU. The pulse counter 6 is reset to zero in advance by a reset signal A that is automatically output when the sectional beam 3 is set in a machine (warper or partial gluing machine). This reset signal A may be output by an operator using a push button switch or the like before the winding operation. The output side of the pulse counter 6 is connected to a part of the input side of the computer 7. Further, a yarn breakage detection sensor 8 and a fuzz detection sensor 10 are provided near the yarn sheet 1, and these are connected to the corresponding yarn breakage detector 9 and fuzz detection device 11, respectively. The yarn breakage detector 9 and the fuzz detector 11 are also connected to a part of the input side of the computer 7.

When yarn breakage or fuzz is detected by the thread breakage detector 9 or the fuzz detector 11 during the winding operation of the sectional beam 3, a detection signal of the defective location is outputted to the computer 7. Therefore, the computer 7 encodes the type of defect and at the same time reads the count signal of the pulse counter 6. The computer 7 encodes the content of the count and the content of the defect and stores it in the storage device 12 as one piece of information.

Normally, when these detection signals are output, the machine stops, and the operator performs processes such as joining broken thread ends and removing fuzz. When the operator has completed the process, he turns on the process completion push button switch 13 and outputs a completion signal B to the computer 7.

When the computer 7 receives the completion signal B, the computer 7 stores the storage device 1
The defect encoding information stored in 2 is changed to a code indicating a processed signal, for example, a thread joining point. A push button switch 14 is provided as an output signal indicating other necessary locations. When this is not detected by the thread breakage detector 9 and is discovered by the operator, or
is for inputting thread breaks that occur during work into the total W machine 7.

In this way, each time the calculator 7 of the recording device 31 receives a signal indicating a defective location, it codes the type of the defect, and calculates the code and the value of the count signal of the pulse counter 6 at that time. The information is stored in the storage device 12.

When the winding of the sectional beam 3 is completed and the operator removes it from the machine, a signal C is input to the computer 7. When this signal C is input, the computer 7 calculates the signal (count content) of the pulse force counter 6 at that time.
and find the difference between it and the value determined by the pulse counter 6 in each piece of information stored in the storage device 12,
These are added to each piece of information as values for the rewinding process. In this way, the necessary number of threads are wound around the sectional beam 3 for the rewinding process, and when the work is completed, the loft end push button switch 15 is pressed by the worker.

In response to this signal, the computer 7 records all the obtained information on the magnetic card 17 using the magnetic card writer 16, and also allows the rewinding operator to predict the work.
The information is made into a list and printed on paper for output by the printer 1B.

FIG. 2 shows an example of the printing format. Sectional bee J in horizontal 1 direction, beam number % of 3 (B
EAM No.) is written, and the position from the start of winding on the rewinding machine (MF, TERONBEAM) is written in the vertical direction.
ER) are shown in the order in which they appear ξ1 in the rewinding process. The type of defect is displayed at the intersection of the beam number and the position from the beginning of the winding. The mark * indicates the occurrence of burrs, B indicates a thread breakage state, and C indicates a thread splicing signal after repair. Also, the types of defects are displayed in a row on the left side.

The magnetic card 17 is inserted into the magnetic card reader 19 of the playback device 32 on the rewinding machine side before the rewinding process of the sectional beam 3, and the information is stored in a total of 111 devices such as the CPU.
20 and output to the controller 27. In the rewinding machine, yarn seams 1- from a plurality of sectional beams 3 are
1 passes between a guide roll 21 and a take-up roll 22, and is wound onto a beam 23 for its use. A pulse cam 24 is attached to the guide roll 21,
The pulse 2 signal of each unit length of the corresponding pulse generator 25 is integrated by the pulse counter 26.

The integrated value of the pulse counter 26 is reset by the operator before the work of rewinding the preparatory sectional beam 3 and is set to zero.

During the rewinding process, the computer 20 successively compares the signal of the defect position obtained by the magnetic card reader 19, that is, the position on the rewinding process, with the integrated signal of the pulse counter 26, and if the value is less than a constant value, When the number of defects decreases, that is, when the defect is near, the type of defect is determined by the type of memory code, and an alarm is issued accordingly.
A machine (rewinding machine) is controlled by controlling the controller 27 of the driving motor 28.
to slow down or stop. In addition, instead of simply applying one action to one defect, if fuzz or thread joints are concentrated in a certain section, measures should be taken to issue a warning or slow down the passage while passing. I do.

Furthermore, an indicator lamp 33 is provided for each of the plurality of sectional beams 3.
The display 34 facilitates the work by lighting the display lamp 333 of the sectional beam corresponding to the defect.

Further, the details of the defect are displayed by a defect display lamp 35 or the like. In this way, the operator can immediately know the corresponding sectional beam 3 and the details of the defect, so that the weft repair work can be carried out efficiently.

In the above embodiment, the pulse cam 4.24 is connected to the guide roll 2.21 and the winding length is used as a signal for the position of the defect, but the position of the defect can be determined by, for example, It can also be measured by connecting a counter and integrating the amount of rotation. Further, in the second embodiment, information is transmitted between the recording device 31 and the reproducing device 32 by the magnetic card 17, but this information can be transmitted by magnetic tape, a photoreactive recording medium, wired or wireless transmission/reception. It can also be composed of vessels, etc. Furthermore, the defect position in the winding process may be determined not by the computer 7 but by the computer 20.

In the present invention, the defects of the yarn sheet in the section 4 of a weaving machine or a sectional gluing machine are automatically memorized, and when the sectional beam is rewinded onto a beam for a loom, that is, when it is unwound on the rewinding machine side. Since the yarn is converted into a signal indicating the defect position and transmitted, defective portions of the yarn can be detected accurately during the rewinding process in the partial sizing machine or warper. Therefore, the management of defective areas in the warping process is automated and the defective areas are reliably repaired, so that high quality woven fabrics can be obtained and the operating rate of weaving can be increased.
