Description

A detecting structure of both penetration and reflection type for the weft straightener with series and parallel array of infrared light emitting diodes}

The present invention relates to a transmissive and reflective combined weft corrector detecting unit structure having a serial / parallel array structure of a light emitting device (infrared light emitting diode), wherein the weft corrector detector of the present invention has a single line of infrared rays arranged in series. Since the light emitted from the light emitting diodes 12 is disturbed by the fabric fabric 23 of thick or dense tissue and is not transmitted effectively, the amount of light reaching the photocell 20 is reduced, so that the light receiving portion 14 is In the case of not operating normally, the infrared light emitting diodes 12 have two lines, three lines as shown in FIG. It is possible to effectively increase the light intensity by arranging them in parallel with each other, and also in the case of the parallel arrangement, the infrared diodes 12 are arranged on the elliptical substrate 13 so that each light emitting source is viewed straight from the lens as shown in FIG. Loss of light source intensity can be prevented by directing the center point of visible fabric and 19 homogeneous infrared light emitting diodes are arranged up and down on the substrate to emit homogeneous light to 15 lens parts fixed to the lens holder 16. A transmissive light emitting unit 17,

 Lens holder 16 when the fabric of the fabric is thick or dense so that the amount of light that penetrates the fabric does not reach the minimum requirement for the normal operation of the detector even when using the improved transmissive light emitting unit 17 described above. The elliptical substrate 13 is formed to be curved to both the left and right sides with respect to the center of the lens fixed to the lens), and the infrared light emitting diodes 12 are arranged in parallel and in parallel on the substrate, thereby increasing the strength of the fabric efficiently. Reflective light emitting unit 15 and configured to use the reflected light by emitting the emitted light,

The lens holder 16 and 15 lenses fixed thereto, and 15 slits formed on the slit film 19 from +14 degrees to -14 degrees with a difference in inclination of 2 degrees up and down corresponding to each lens. (25), the photocell substrate 24 and the electricity generated from the photocell is disposed behind the slit film 19 attached to the photocell 20 to convert the amount of light passing through each slit into an electrical signal It consists of a light receiving unit 14 to detect the inclination of the far end from +14 degrees to -14 degrees by using the signal amplification and the control board 11 is provided with an electronic circuit that amplifies the conventional signal.

In general, the specific structure of the weft straightener detection unit varies depending on the company producing the weft straightener, but the main part thereof is divided into the light emitting part and the light receiving part, and the light emitting part includes an incandescent lamp 21 made of tungsten or a halogen rod bulb 22. It is used.

In addition, the light receiving unit 14 passes through the slit film 19 and the slit film 19 for detecting the inclined state of the fabric from the lens 10 and the lens 10 to form an image of the fabric by collecting light from the fiber fabric. A photocell 20 that converts the intensity of light into an electrical signal is generally used.

On the other hand, the weft straightener detector of the type described above has a disadvantage in that the bulb needs to be replaced after a certain period of time due to long life due to the lifespan of the bulbs 21 and 22 used as light emitting units.

At this time, when the light bulbs 21 and 22 are replaced, the fine adjustment relationship between the light emitting unit and the light receiving unit changes, so that the sensing state of the detecting unit becomes uneven, which acts as a factor of deterioration in quality, which causes a problem of having to readjust the detecting unit. .

In addition, when processing a thick or dense fabric, even if it is necessary to increase the brightness of the light bulb to increase the amount of light passing through the fabric, there is a risk of fire due to the heat of the fiber due to the heat generation of the light bulb. This makes it difficult to light the bulb beyond a certain standard.

This is because the fabric fabric 23 processed by the sensing part passes near the field (about 20 cm or less) from the light bulbs 21 and 22, and due to the nature of the fiber processing process, fabric debris accumulates around the light emitting part cases 29 and 30. This is because there is a danger (approximately 1 light bulb generates more than 100 watts of light, which may cause a fire.) In this case, in order to prevent the risk of fire, light intensity may be obtained by using a plurality of light bulbs in parallel in parallel. Although the volume of the bulb is larger than the size of the lens 10 used in the light receiving unit 14, the light of the added light bulb does not properly project the light on the light receiving unit 14, thereby failing to achieve the purpose.

Therefore, in the conventional light emitting unit, when using the incandescent bulb 21, one is used, and when using the halogen rod bulb 22, only two are used in parallel as shown in FIG.

As described above, the two problems of the light emitting part of the conventional weft straightener detection unit were examined. The first problem is that the lifespan of the light bulb has a limit, and the need to be replaced every predetermined time. Even if the tissue is thick or dense, the amount of light that penetrates the fabric is not sufficient, and thus the brightness of the bulb light cannot be further increased even when the function of the sensing unit is lost.

On the other hand, the light-receiving unit 14 of the conventional weft corrector detecting unit is composed of a slit film 19 and a photocell 20 to form a lens 10 and the image of the fabric as shown in Figure 1, the slit film 19 ) Uses a radially gathered form as shown in FIG. 3 and a method of being arranged in series as shown in FIG. 5.

In addition, the lens 10 may use one large diameter lens capable of irradiating the image of the fabric to all the slits at once as shown in FIG. 4, and a small diameter of irradiating the image of the fabric to each of the slits as shown in FIG. 6. One independent lens may be used.

The method used as shown in FIG. 6 is a conventional method using 11 independent lenses, which uses a specially manufactured slit film 19 as shown in FIG. 5 to detect that the weft of the fabric is inclined. The slit in the center has a slope of 0 degrees and ascends above it, the slit's slope increases by +2 degrees, and the last slit has a slope of +10 degrees, and the slit's slope decreases by -2 degrees as it descends from the center slit. Since the slit has a slope of -10 degrees, the slit 1 is +10 degrees from the top, the slit 2 is +8 degrees,. Slit 6 is 0 degrees. , Slit 11 has a slope of -10 degrees. In order to show the inclination from +10 degrees to -10 degrees, 11 slits 25 are required, and one lens is used for each slit, thereby requiring 11 lenses.

And when processing the fabric in the field, there is a difference in degree depending on the type of fabric, but in order to find out the condition of the weft of the fabric, it is generally combined with two up and down, including the middle slit (slit 6: slant 0 degree). Five slits (slits 4, 5, 6, 7, and 8) are used and the remaining slits have a function as a preliminary slit to prevent malfunction when the fabric is severely twisted.

In the above situation, the preliminary slits may be used critically in the case of specially processing the fabric, and this is the case in which the weft of the fabric is intentionally inclined and this is called skew processing in the workplace. Such skew processing is required to wash the fabric according to the type of fabric (especially jeans), so that the fabric is twisted and the cutting line is skewed so that the fabric comes back straight after washing by turning a certain amount of weft of the fabric in the opposite direction. This is because the workplace uses the method of making the cutting line fit right.

In this skewing process, the weft straightener does not consider the center slit (slit 6: 0 degree inclination) as the normal processing, but processes the fabric by considering it as the slit out of the center. For example, suppose that +4 degrees of skew processing is applied. The fourth slit from above (slit 4: slant +4 degrees) becomes the reference slit, and the fabric is processed by using two slits each up and down about it. The slit used for the slit is 2, 3, 4, 5, 6, etc., and all 5 slits are used.

As another example, to perform skew processing of +6 degrees, the slits 1, 2, 3, 4, 5, etc. are all set using the third slit (slit 3: slant +6 degrees) from the top as in +4 degrees. You will use a slit to skew

For skewing at +8 degrees, the reference slit is the second slit from the top (Slit 2: Slope +8 degrees), so you can use Slits 3 (tilt +6 degrees) and Slit 4 (tilt +4 degrees). Since only slit 1 (tilting +10 degrees) can be used in the upper part, in order to find out the weft condition of the fabric, it does not satisfy the condition that additional two consecutive slits are needed up and down about the standard slit. 8-degree skewing is not possible with 11 slit structures.

Therefore, if there are 11 slits (maximum inclination 1010 degrees), the maximum inclination for skewing cannot exceed 6 degrees.

On the other hand, in the fabric processing site, skew processing up to ㅁ 10 degrees may be desired, so in order to satisfy the skew processing up to this case, 15 independent slits are used instead of 11 (slope slant: -14 degrees to +14 degrees). However, in the conventional weft straightener detection unit, it was impossible to use 15 slits, so only 11 slits could be used, so it was impossible to perform skewing at 10 degrees.

The reason is that the diameter of the circular lens allocated to each slit is about 6mm, so that when 11 lenses are used, the total length of the lenses arranged in series becomes 66mm (6mm611). Since the length of the light-emitting body of the halogen rod bulb that can be purchased is approximately 70 mm, it is not a problem to face each other. However, when 15 lenses required for skewing of 10 degrees are used, the total length of the lenses arranged in series is 90 mm. This is due to the increase of (6mm 증가 15), so when using a 70mm halogen bar bulb, the one or two lenses at both ends do not receive light properly and the detector cannot operate normally.

In addition, when the incandescent lamp is used, there is a problem in the size of the light emitter as described above, and thus it was impossible to obtain a bulb suitable for using 15 lenses.

Therefore, even if the light receiving part of the conventional weft straightener detector is required to have a slit having a larger inclination when a work such as skew processing is required, the maximum slope of the slit is +10 degrees due to the physical size limitation of the light emitting bulb as described above. There was a disadvantage that can not be out of the range of -10 degrees.

However, when the number of slits required for skew processing of 10 degrees is 15, the infrared light emitting diode 12 is used as a light emitting source so that one infrared light emitting diode per slits is matched to 15 infrared light emitting diodes. When the diodes 12 are connected in series, the size of one infrared light emitting diode is about 6 mm, which is small, so there is no problem in series configuration. Even when 15 lenses are used, uniform light is applied to the lenses at both ends. It is possible to project the intensity of the skew processing of size 10 ㅁ will be possible.

On the other hand, as a means for more precisely detect the warped state of the fabric fabric is the application of the patent application No. 10-1998-0043211 of the application of the "weft bend detection device of automatic fabric straightener for fabric", which is a fabric A light source that emits light having strong straightness of a predetermined intensity that can pass through, a frame having a through hole having a predetermined size formed on the front surface thereof, and a double-row lens is arranged in a line to face the light source with the fabric interposed therebetween and the fabric and the lens Light passages are formed to pass through the incident light through the lens, and the lens holder is formed at the center of the rear surface of the through hole of the frame, and the lens holder is positioned at the same position as the light path of the lens holder at the rear of the lens holder. The film slits are formed in line with slits of the inclined double row, and are formed at the same positions as the slits on the back surface of the film slits, respectively. A plurality of photocells for converting the optical signals into electrical signals, a substrate to which the photocells are fixed and attached, and to transmit electrical signals outputted from the photocells through wires, and to connect signals from the substrates A weft bent detecting part with a connector integrated, and a control circuit part connected to the connector to amplify and output a signal is configured to more accurately detect the weft bend of the fabric in the dyeing process or the tent process.

Here is a brief look at the difference between the present invention and the present invention.

The present invention is a configuration for obtaining a plurality of information on the state of the fabric at the same time in a wide range as possible to more accurately know the state of the surface of the fabric, the present invention is the light emitted to the fabric for reasons such as the texture or thickness of the fabric The present invention relates to a configuration that can effectively increase the intensity of light in the case of a loss of the function of the detector due to the improper transmission of the fabric.

Therefore, the invention of the prior application has the disadvantage that the present invention is intended to improve the inconvenience of having to replace the bulb after a long time due to the limited life of the bulb, attenuation of the sensing ability according to the texture or thickness of the fabric, fire due to excessive heat Risk, ㅁ 10 degree of skew processing, even if it is necessary to increase the number of lenses to 15, due to the size limitation of the light emitters such as bulbs can not be increased to 15, the difference between the amount of light incident on each lens It has all the weaknesses such as complicated configuration of electronic circuit to compensate.

The present invention has been made to solve the above problems, the weft corrector detector of the present invention is a fabric fabric of the thick or dense tissue emitted from a series of infrared light emitting diodes 12 arranged in series ( 23, the amount of light reaching the photocell 20 is reduced because it is not transmitted effectively, so that the infrared light emitting diodes 12 are doubled as shown in FIG. 11 when the light receiving portion 14 does not operate normally. , 3 lines… It is possible to effectively increase the light intensity by arranging them in parallel with each other, and also in the case of the parallel arrangement, the infrared diodes 12 are arranged on the elliptical substrate 13 so that each light emitting source is viewed straight from the lens as shown in FIG. Loss of light source intensity can be prevented by directing the center point of visible fabric and 19 homogeneous light emitting diodes are arranged up and down on the substrate in a homogeneous light to 15 lens parts fixed to the lens holder 16. A transmissive light emitting unit 17 capable of emitting radiation,

It is a perspective view of the state formed so that it may transmit and reflect.

 First, in the improved part of the sensing unit, a light emitting unit that combines a transmissive or reflective type is used, and the transmissive light emitting unit 17 faces the light receiving unit 14 with the fabric fabric interposed therebetween, to provide light to the fabric fabric. The light is transmitted through the fabric fabric to reach the lens 10 of the light receiving portion, the reflective light emitting portion 15 is projected to the fabric fabric while being on the same side as the light receiving portion 14 relative to the fabric fabric Thus, the light reflected from the fabric fabric emits light to reach the lens 10 of the light receiver, so that the light receiver 14 detects the state of the fabric fabric.

Generally, the weft straightener finds the state of the fabric fabric by using the transmissive light emitting unit 17, but it is preferable to use the reflective light emitting unit 15 according to various conditions such as the structure, thickness, surface state, and pattern of the fabric fabric. In the present invention, the detection unit of the weft straightener is to be able to combine the transmission type and the reflection type.

In the case of the transmissive light emitting part 17, the intensity of light transmitted through the fabric filament 23 decreases due to the thick or dense fabric fabric, or in the case of the reflective light emitting part 15, Therefore, if the intensity of the reflected light decreases and the amount of light emitted from the infrared light emitting diodes 12 of one line does not provide enough light for the light receiving unit 14 to operate correctly, an elliptical shape as shown in FIG. 2 lines and 3 lines of infrared light emitting diodes 12 on the substrate 13 of the structure. It is possible to increase the intensity of light by constructing an increased type of light source.

At this time, the additionally increased light source is configured to increase the efficiency of the light source by directing toward the center point of the fabric fabric portion seen in a straight line from the lens 10 as shown in FIG.

In addition, the infrared light emitting diode 12 used at this time is small in size (diameter: about 6 mm), and thus is suitable to be arranged in parallel and in parallel as shown in FIG. 11, so that it is easy to increase the intensity of the light source, and the infrared light emitting diode 12 ), Since the life of the semi-permanent light bulb as in the case of using the incandescent bulb 21 or halogen bar bulb 22, the inconvenience of replacing the bulb disappears.

On the other hand, dozens of fixing grooves 18 are formed on the surface of the elliptic substrate 13 in the form of longitudinal and transverse lattice.

In addition, each of the infrared light emitting diodes 12 is fixed to the fixing groove 18, and in this case, the fixing method is a signal amplification and a structure capable of receiving electricity from the control plate 11.

In addition, in order to enable skew processing having an inclination of up to 10 degrees, 15 slits 25 and a photocell 20 as shown in FIG. 8 are required. When used, the size of the luminous body is small, so the center slit receives enough light, but the one or two slits on the edge side receive the light weakly, so that the light irradiated to each slit is not uniform. The diodes 12 are arranged face to face with the lens 10, one for each slit, so that the lens on the edge side also receives and receives sufficient light.

However, even in this case, the infrared light emitting diode 12 does not only affect the lens 10 directly facing, but also has a region (about 30 degrees) that affects the light emitted. Will be affected.

Therefore, as shown in (a) of FIG. 10, the position of the fabric facing the lens 10 in the center portion is the same as the influence from the neighboring infrared light emitting diodes, so that the light is uniformly received, but the two are positioned outside. The position of the fabric facing the lens of the degree is less affected by neighboring infrared diodes, thus reducing the light intensity.

For this reason, in order to irradiate uniform light to all 15 lenses 10 when 15 lenses are used, two infrared light emitting diodes 12 are additionally required on both outer sides thereof, as shown in FIG. 10 (b). By using 19 diodes 12, it is configured to be able to shine a homogeneous light to 15 lenses 10 of the light receiving portion 14.

As described above, the light emitting source uses the infrared light emitting diodes 12 as shown in FIGS. 10 (b) and 11 to illuminate homogeneous light to 15 lenses 10 fixed to the lens holder 16. If the light is weak, it is a configuration to increase the intensity of the light by arranging a plurality of infrared light emitting diodes 12 of a plurality in a row on the elliptical substrate 13 of the form as shown in FIG.

Meanwhile, as shown in FIG. 13, the light receiving unit 14 has a light through hole through which 15 lenses 10 may be attached to the lens holder 16, and a slit film 19 is attached to the lens holder 16, followed by a photocell. The substrate is attached and the photocell substrate is connected to the signal amplification and the control board.

In addition, as shown in FIG. 14, the light source of the reflective light emitting unit 15 that is integrally coupled with the elliptical substrate 13 and radiated from the dozens of infrared light emitting diodes 12 formed on the elliptic substrate 13 is reflected on the fabric surface to receive the light. The light is configured to be incident on the lens 10.

On the other hand, the portion of the slit film 19 formed integrally with the photocell substrate 15 is to use a method of being in close contact with the back of the lens holder 16, which is the same or similar to the prior application No. 10-1999-0043211 Do.

That is, the slit film 19 is located on the rear surface of the lens holder 16 and shows a difference in inclination of 2 degrees from horizontal to horizontal and up to +14 at a position coinciding with the light path 26 of the lens holder 16. In the figure, it consists of a single film with a number of slits inclined to -14 degrees.

In addition, the photocell 20 is disposed on the rear surface of the slit film 19 and is composed of a plurality in the state inclined at the same angle at the same position as the slit, respectively, attached to the photocell substrate 24, the incident optical signal It converts into an electrical signal.

That is, when the weft sensing unit having the transmissive light emitting unit 17 or the reflective light emitting unit 15 is fixed to one side of the woven fabric fabric, the light emitted from the light emitting unit and transmitted or reflected through the fabric is the lens holder 16. After forming through the image of the lens 10 formed in the image, the resulting image of the fabric is passed through the corresponding slit film 19 and the photocell 20 according to the degree of inclination and converted into an electrical signal and the converted signal is connected to the connector 27 The signal amplification and control board 11 is input through the signal amplification and control board 11, and the signal amplification and control board 11 amplifies the input signal and calculates an average or maximum value to output a control signal. It is configured to automatically detect the bending of the fabric by detecting the bending.

Referring to the operation and effects of the present invention made of the above configuration in detail as follows.

First, as the light emitting sub-element, using the infrared light emitting diode 12 whose bulb life is semi-permanent, the inconvenience of replacing the bulb due to the life of the light bulb when using the conventional light bulbs 21 and 22 is eliminated, and the infrared light emitting diode 12 is arranged in the vertical direction in the vertical direction on the substrate 13 to be able to shine a homogeneous light to the 15 lenses 10 of the light receiving portion 14, so that the intensity of the light is not uniform electronic circuit The signal amplification and control circuit 11 can be simplified because there is no need to compensate.

At this time, the amount of light emitted from one line of the infrared light emitting diodes 12 and transmitted through the fabric is reduced due to the structure or thickness of the fabric and thus does not reach the minimum requirement for correct operation of the sensing unit. 13) by using a plurality of infrared light emitting diodes 12 composed of a plurality of lines, two lines, three lines ... The function of the sensing unit was improved by increasing the intensity of the light with the light-emitting source in increments.

At this time, each of the strings can further increase the efficiency of the light source by facing the distal end portion of the lens 10 as seen in a straight line as shown in FIG.

In addition, unlike the light bulbs 21 and 22, the infrared ray diode 12 has a very low heat generation, and thus the risk of fire due to excessive heat generation of the light bulb disappears.

On the other hand, the light receiving unit 14 is composed of a lens holder 16, a lens, a slit film, a photo cell substrate 15 and a signal amplification and control board 11, the light emitted from the infrared light emitting diode reflected on the fabric is a lens Each of the lenses 10 of the holder 16 is formed as an image of a fabric, and the image of the thus formed fabric is a lens 10, a lens holder 16, a slit film 19, and a photocell 20 corresponding to the degree of inclination. It is transmitted to) and is converted into an electrical signal and transmitted to the controller to be used as a control signal to correct the grain of the fabric.

Then, the oval substrate 13 is arranged on the left and right sides of the lens holder 16 of the light receiving unit to form the reflective light emitting unit 15 so that the reflective light emitting unit 17 is not suitable according to the fabric fabric conditions. By allowing the light emitting unit 15 to be selected, it is possible to weft correction for more and different kinds of fabrics.

The present invention described above is limited to the embodiments and the accompanying drawings as various substitutions and modifications are possible within the scope without departing from the spirit of the present invention for those skilled in the art. It is not.

According to the present invention as described above, since the life span is semi-permanent because the transmissive and reflective type weft straightener detection unit using the infrared light emitting diode is eliminated because the burden of the bulb replacement according to the life of the light emitting source is eliminated (after service) ), And when the amount of light emitted by the light emitting part is largely required, the light emitting part can be arranged in parallel in order to achieve the purpose easily, so it is convenient for processing thick fabrics and the amount of heat generated even when strong light is emitted. As it is weak, there is no risk of fire due to the light emitting source, and it is a transmissive and reflective type to adapt to various fabrics, and there is no problem to increase the number of lenses used for skew processing of 10 degrees to 15, and each lens Since the amount of light projected on the lens can be maintained uniformly, the difference in the amount of light input to each lens Since the need for compensation is eliminated by the circuit, it helps to reduce the complexity of the electronic control circuit so that not only the production of the weft calibrator but also the work efficiency can be improved and the excellent performance can be exerted after the management.
