Description

A computer-readable storage medium recording a flux filling rate determining device, a flux filling rate determining method, a flux filling rate determining system, and a flux filling rate determining program. A FILLING RATIO OF FLUX}

The present invention relates to a flux filling rate determination device for use in a device for producing a flux lead wire suitable for an arc welding wire for automatic or semi-automatic welding used for welding mild steel, high tensile strength steel, stainless steel, or heat resistant steel, and a flux filling rate determining method using the same. And a flux fill factor determination system, and a flux fill factor determination program.

Flux lead wire is manufactured by the following manufacturing methods. First, the metal base plate is bent in a U shape from both sides in the plate width direction, and the flux is filled in the inside of the metal base plate that is bent. Next, the flux-filled metal base plate is formed into a tubular metal shell to form a metal shell, and then the metal shell is thinned to a predetermined diameter by drawing, and the flux is formed along the longitudinal direction. An incoming wire is produced. And in the manufacture of such a flux lead wire, the flux is not filled due to the flux supply unit (BF) or more, the balance of the metal plate supply speed and the flux supply amount, the vibration of the equipment or material, or the like, the flux Part where the filling rate (mass% of flux with respect to the total wire mass per unit length) does not satisfy an allowable range may occur. For this reason, it is necessary to detect such a flux filled foreign material which adversely affects welding quality, and to exclude it from mixing as a product.

Conventionally, as a method of inspecting and excluding a flux-filled foreign product, a sample having a predetermined length is extracted from a flux inlet wire as a product, and the sample is fracturely inspected to directly measure the mass, volume, or cross-sectional area of the flux, and the flux from the value. A filling rate is calculated and the foreign material of a flux filling rate is excluded from the test result. Such a test has a problem that reliability is inferior to a full test because it is an extraction test. In addition, since such inspections require destructive inspections by human hands, a long working time is required, and the workload is also increased, and the abnormal manufacturing lot until the corrective cause of the inspection is identified and corrected. lot is also destroyed, resulting in low productivity.

In order to solve this problem, it is desired to exclude the foreign material of the flux filling rate by inspecting the flux filling rate non-destructively and online during wire manufacture. As a flux filling rate detection device used for this purpose, Patent Document 1 proposes to pass a flux inlet wire into a coil, calculate a flux filling rate using an electromagnetic induction phenomenon, and detect a foreign product by the calculated flux filling rate. have.

Specifically, when an alternating current of high frequency flows through the coil, an induction current is generated in the metal sheath of the flux lead wire by electromagnetic induction, and the impedance of the coil changes due to the magnetic field generated by the induction current. And in the flux lead wire manufactured by drawing, since the outer diameter side of a metal outer sheath is regulated and drawn, there exists a tendency for a metal outer shell to expand to an inner diameter side. Therefore, if the amount of flux filling is small, the thickness of the metal shell is thick. If the amount of flux filling is large, the thickness of the metal shell tends to be thin. In addition, the impedance of the coil is greatly reduced when the thickness of the metal shell becomes thick, that is, when the flux filling rate decreases. Therefore, in patent document 1, the flux filling rate of a flux lead wire is calculated by the change of the impedance of a coil.

Japanese Unexamined Patent Publication No. 1997-239588

However, the amount of change in induced current generated by electromagnetic induction described above, that is, the amount of change in impedance of the coil, is an effective level when determining the presence or absence of flux in the wire, and it is not possible to quantitatively grasp the flux charge amount. The calculation precision of was low. Therefore, although the commodity which is not filled with flux can be detected, even if the flux is filled, it is not able to detect the commodity whose flux filling rate exceeds the permissible range. Therefore, in the flux filling rate detection apparatus of patent document 1, there exists a problem that the detection precision of a flux filling rate is low, and the detection precision of this product also becomes low.

Moreover, in the flux filling rate detection device of Patent Literature 1, as described above, since the calculation accuracy of the flux filling rate is low, when the flux-free article is detected, the inspection of the produced product is stopped after stopping the manufacturing apparatus. The flux filling rate is measured by As a result, once this product is found, it is necessary to remove the product back to the regular product, resulting in a decrease in product throughput and a decrease in productivity.

Here, the present invention was devised to solve such a problem, and the problem is that when used in the apparatus for producing a flux inlet wire, the calculation accuracy of the flux filling rate is high, whereby the detection accuracy of the foreign product is excellent and productivity The present invention provides an excellent flux filling rate determining device, a flux filling rate determining method and a flux filling rate determining system using the same, and a flux filling rate determining program.

In order to solve the said subject, the flux filling rate determination apparatus which concerns on this invention manufactures a flux lead wire by filling a flux in the inside of the metal base board curved in the plate width direction, and shape | molding this metal plate in tubular form. A flux filling rate determination device for arranging a flux filling rate by arranging in a manufacturing apparatus, the flux width measuring device being a plate width direction of the metal slab measured immediately after filling of said flux by a sensor placed upward with respect to the plate surface of said metal plate filled with said flux. Input section for inputting the upper surface coordinate of the flux, the inner surface coordinates of the metal slab in the plate width direction of the metal slab not filled with the flux measured by the sensor, and the allowable range of the predetermined metal slab mass, flux specific gravity and flux filling rate. And a storage section for storing the flux cross-sectional area as the flux top surface coordinates and the inner surface coordinates of the metal base. A flux cross-sectional area calculating unit for calculating the flux cross-sectional area and the flux cross-sectional area by a predetermined length to calculate a flux filling capacity, converting the flux filling capacity into a flux filling mass based on the flux specific gravity, and the flux filling mass and the metal plate And a flux filling rate calculating unit for calculating the flux filling rate by mass, and a judging unit for determining that the calculated flux filling rate satisfies the allowable range of the flux filling rate, and determines that the case where the flux filling rate is not satisfactory is defective. It features.

According to the above configuration, the flux top surface coordinates and the inner surface coordinates of the metal base are measured by a sensor, and the flux cross-sectional area is calculated in the flux cross-sectional area calculating section using these curved coordinates, and the flux cross-sectional area is used to calculate the flux in the flux filling rate calculation unit. The filling rate is calculated. Therefore, since the calculated flux filling rate is calculated from the physical quantity directly related to the flux filling rate of the flux cross-sectional area, the calculation accuracy is higher than that estimated from the physical quantity indirect to the flux filling rate of the induced current generated in the wire as in the prior art. The detection accuracy of this product of flux filling rate is improved. Therefore, when this product is detected, there is no need to perform the destruction inspection by the product as in the prior art, so that the product throughput does not decrease by the destruction inspection, and the productivity of the wire is improved. In addition, since the flux top surface coordinate used for the calculation of the flux cross-sectional area is measured immediately after the filling of the flux before the tubular molding of the metal base plate, even when this product is detected, the spreading range of the product becomes narrow, and the productivity of the wire It is further improved.

The flux filling rate determining device according to the present invention is the flux filling rate determining device, in which the input unit measures immediately after filling of the flux with a first sensor disposed above the plate surface of the metal plate filled with the flux. Flux top surface coordinates in the plate width direction of the metal plate and a metal in the plate width direction of the metal plate measured immediately after filling of the flux by a second sensor disposed below the plate surface of the metal plate filled with the flux. The outside plate coordinates are input, and in the storage unit, the cross section of the metal plate in the plate width direction of the metal plate that is not filled with the flux is further stored, and in the flux cross-sectional area calculating unit, the flux top surface coordinates and the outside plate of the metal plate Calculating the total cross-sectional area using coordinates, and calculating the flux cross-sectional area with this total cross-sectional area and the cross section of the metal base. It characterized.

According to the above configuration, the flux top surface coordinates and the metal plate outer surface coordinates are measured by the first and second sensors, and using the curved surface coordinates and the metal plate cross-sectional area previously stored in the storage unit, the total cross-sectional area and The flux cross-sectional area is calculated, and the flux filling rate is calculated in the flux filling rate calculation unit using this flux cross-sectional area. Therefore, since the calculated flux filling rate is calculated from the flux cross-sectional area, which is a physical quantity directly related to the flux filling rate, similarly to the flux filling rate control device, the calculation accuracy of the flux filling rate is increased, thereby improving the detection accuracy of the foreign material of the flux filling rate. The productivity of the wire is improved.

In addition, since both curved coordinates of the top surface coordinates of the flux and the outer surface coordinates of the metal base are measured, even when the metal base moves in the up, down, left or right directions due to vibrations during the flow, the movement of the metal base is calculated to the flux cross-sectional area. There is no such thing as affecting. Therefore, the calculation precision of a flux filling rate becomes high, and the detection precision of the foreign material of a flux filling rate improves. Furthermore, similar to the flux filling rate control device, since both curved coordinates of the flux top surface coordinates and the outer surface coordinates of the metal plate used for the calculation of the flux filling rate are measured immediately after the flux filling before the tubular molding of the metal plate, the productivity of the wire is reduced. It is further improved.

In the flux filling rate determining device according to the present invention, it is preferable that the calculated flux filling rate in the determining unit of the flux filling rate determining device further adds a predetermined correction value to the flux filling rate.

According to the said structure, since the correction value is further added to the flux filling rate in a determination part, the calculation precision of a flux filling rate becomes higher, and the detection precision of this commodity of a flux filling rate improves more.

The flux filling rate determining method according to the present invention is a flux filling rate determining method for determining a flux filling rate using the flux filling rate determining device, wherein the flux width measured in the sensor immediately after the filling of the flux is measured in the plate width direction.

Therefore, when this product is detected, since it is not necessary to perform the destruction inspection by a product like the conventional one, the productivity of a wire improves. In addition, since the curved surface coordinates input in the first step are measured immediately after the filling of the flux before the tubular molding of the metal base plate, even when this product is detected, the spreading range of the product is narrowed, and the productivity of the wire is further improved. do. Further, the flux filling rate calculated in the third step is determined to be good or bad in the fourth step, and when it is determined to be defective, the operation of the manufacturing apparatus is stopped or the cause of abnormality is corrected, so that the spreading range of this product is narrowed. As a result, the productivity of the wire is further improved.

The area obtained by subtracting the metal plate cross-sectional area S2 from the total cross-sectional area S1 defined as the area between the curved surface coordinates (the metal plate outer surface coordinates ZMb) of the curved surface drawn by the outer surface of the metal plate 101 is the flux cross-sectional area ( S) (S = S1-S2). 3 (a) and 3 (b), the total cross sectional area S1, the cross section S2 of the metal base S2 and the case where the flux upper surface coordinate ZF and the metal base outer surface coordinate ZMb are limited by the inspection area. Flux cross-sectional area (S) was described.

The determination apparatus 1 of the first embodiment can calculate the flux cross-sectional area S with high accuracy when the normal production, specifically, the metal base 101 flows at a normal speed. However, when the metal base plate 101 is flowed at a high speed faster than the normal speed in order to improve productivity, the following problems tend to occur.

In the high speed flow, vibration of the metal base plate 101 in the up, down, left, and right directions is likely to occur. The vibration of the metal base plate 101 moves the flux upper surface coordinate ZF measured by the first sensor 10a in the vertical direction, the horizontal direction, or the inclined direction in order to calculate the flux cross-sectional area S. On the other hand, the inner surface coordinates ZMa of the metal base as a reference for the calculation of the flux cross-sectional area S are curved surface coordinates measured by the metal base 101 in a state where there is no vibration in advance. Therefore, as shown in Fig. 2B, the flux cross-sectional area calculated by the determination device 1 of the first embodiment is calculated by calculating the cross-sectional area that is increased or decreased by the error? S as compared with the actual flux cross-sectional area S. It is easy to become, and the calculation precision of the calculated flux cross section is easy to fall. In addition, in FIG.2 (b), the case where the flux upper surface coordinate ZF moved to the upper direction by the vibration of the metal base plate 101 was described.

In the determination apparatus 1A of the second embodiment, even when the vibration of the metal base 101 as described above occurs, the first and second sensors 10a and 10b are used to calculate the flux cross-sectional area S. FIG. The measured flux top surface coordinates ZF and the metal base plate outer surface coordinates ZMb are moved in the same direction by the vibration of the metal base plate 101. Therefore, in 1A of determination apparatuses of 2nd Embodiment, since the error (DELTA) S does not generate | occur | produce in the flux cross-sectional area computed, calculation precision becomes high.

<Flux filling rate determination method>

Next, the flux filling rate determination method (hereinafter, referred to as a determination method) of the present invention will be described. In addition, the structure of a determination apparatus, a sensor, and a manufacturing apparatus is demonstrated with reference to FIG. 1, FIG. 5 (a), (b).

As shown in FIG. 4, the determination method of this invention is a flux charge plate which determines a flux charge rate using the flux charge rate determination apparatus 1 (1A) of 1st Embodiment or 2nd Embodiment mentioned above. The first step S1 of inputting the curved surface coordinates of the plate width direction of 101A, the second step S2 of calculating the flux cross-sectional area S, and the third step S3 of calculating the flux filling rate F; ) And a fourth step S4 for determining whether the flux filling rate F is good or bad.

(First step)

The first step S1 inputs the curved surface coordinates of the plate width direction of the flux charging plate 101A measured immediately after the flux 102 has been charged by the sensor 10 to the input unit 2, and the curved coordinates are fluxed. It is a process of outputting to the cross-sectional area calculating part 4.

Here, since the curved coordinates input and output are measured immediately after the filling of the flux 102, the flux cross-sectional area S and the flux filling rate F calculated from these curved coordinates are as follows. Since it becomes the thing in the initial stage of the manufacturing process of), the spreading range when the foreign material of flux filling rate F is detected becomes narrow, and the fall of productivity can be prevented.

And when using the determination apparatus 1 of 1st Embodiment, the curved surface coordinates measured the flux upper surface coordinate ZF measured by the 1st sensor 10a arrange | positioned upward with respect to the board surface of the flux charging plate 101A. ) (See FIG. 2A). In addition, when using the determination apparatus 1A of 2nd Embodiment, the flux upper surface measured by the 1st and 2nd sensors 10a and 10b arrange | positioned upwards and downwards with respect to the plate surface of the flux charge plate 101A. Coordinates ZF and metal plate outer surface coordinates ZMb (see FIG. 3A).

(Second step)

In the second step S2, in the flux cross-sectional area calculating unit 4, the flux cross-sectional area S is calculated using the curved surface coordinates output in the first step S1, and the flux cross-sectional area S is used as the flux filling rate. It is a process of outputting to the calculating part 5.

The flux cross-sectional area S is calculated by using the determination device 1 of the first embodiment in the region between the flux upper surface coordinate ZF and the metal plate inner surface coordinate ZMa output from the storage unit 3. The area of is calculated as the flux cross-sectional area S (see Fig. 2A). In addition, when using the determination apparatus 1A of 2nd Embodiment, the area of the area | region between flux upper surface coordinate ZF and the metal plate outer surface coordinate ZMb is computed, and it is set as total cross-sectional area S1 (FIG. 3). (a)] The flux cross-sectional area S (S = S1-S2) is calculated by subtracting the cross section area S2 of the metal base stored in the storage unit 3 from this total cross-sectional area S1 (Fig. 3 (b)]. 3 (a) and 3 (b), the total cross sectional area S1, the cross section S2 of the metal base S2 and the case where the flux upper surface coordinate ZF and the metal base outer surface coordinate ZMb are limited by the inspection area. Flux cross-sectional area (S) was described.

(Third step)

In the third step S3, in the flux filling rate calculation unit 5, the flux filling rate F is calculated using the flux cross-sectional area S output in the second step S2, and the flux filling rate F is calculated. Is a process of outputting to the judgment part 6.

The calculation of the flux filling rate F is performed in the following order (S3-1) to (S3-3).

(S3-1) A predetermined length L (for example, L = 1 mm) of the flux charging plate 101A, or a predetermined length (for example, T = 1 second) for each predetermined time T (for example, T = 1 second) For example, using the flux cross-sectional area S calculated when the first step S1 and the second step are executed up to 75 mm or a predetermined time (for example, 60 seconds), the function S (L) or S ( Define T).

(S3-2) The flux filling capacity V is calculated by integrating the function S (L) or S (T) for a predetermined length (for example, 75 mm) or for a predetermined time (60 seconds).

(S3-3) The flux filling mass (V) is converted into the flux filling mass (F1) by the flux specific gravity stored in the storing unit (3), and converted into the flux filling mass (F1) and the storing unit (3). The flux filling rate F is calculated by the following equation (1) using the stored metal slab mass (F2).

[Equation 1]

F (%) = [F1 / (F1 + F2)] × 100

Since the flux filling rate F calculated in this way is calculated from the physical quantity directly related to the flux filling rate F called flux cross-sectional area S, calculation accuracy becomes high and the detection accuracy of this product of the flux filling rate F is excellent. Done. Therefore, when this product is detected, there is no need to perform a breakdown test, so that the product throughput does not decrease by the breakdown test, and the productivity of the flux lead wire 101C is excellent.

(Fourth step)

In the fourth step S4, the determination unit 6 compares the flux filling rate F output in the third step S3 with the allowable range of the flux filling rate F stored in the storage unit 3. Therefore, it is a process of judging the good or bad of the flux filling rate F, and when it judges that it is defective, the operation | movement of the manufacturing apparatus 200 is stopped, ie, the determination of the flux filling rate F is complete | finished. Further, in the fourth step S4, even when it is determined that the flux filling rate F is good, the flux charger (according to the deviation from the allowable range center value, that is, the difference between the flux filling rate F and the allowable range center value) In 202, a control for increasing or decreasing the flux supply amount or the flow rate of the metal base 101 may be executed.

In the fourth step S4, a predetermined correction value is added to the flux charge rate F output in the third step S3, that is, calculated, and the flux charge rate (correction flux charge rate) to which the correction value is added is allowed. By determining whether or not the range is satisfied, it is preferable to determine whether the flux filling rate of the flux lead wire 101C is good or bad. Here, it is preferable to perform a preliminary experiment etc. beforehand, and to set it in consideration of the error of flux specific gravity, the error by attachment of a sensor, etc. from the result.

In addition, when 1 A of determination apparatuses of 2nd Embodiment are arrange | positioned to the manufacturing apparatus 200, the sensor 10 arrange | positioned 1st and 2nd sensors 10a which were arrange | positioned above and below the flux charging plate 101A, 10b), the curved surface coordinates to be measured are the flux upper surface coordinates ZF and the metal plate outer surface coordinates ZMb (see FIG. 3 (a)).

(sensor)

In the determination system 300, the configuration of the sensor 10 is not particularly limited as long as it can measure the curved coordinates of the flux charging plate 101A, but a laser displacement meter in which the measurement is performed using a laser beam is preferable. . In addition, measurement of the curved surface coordinates by the sensor 10 is performed by emitting laser light from the sensor 10 in the plate width direction of the flux charging plate 101A at predetermined intervals or continuously, and measuring the reflected light. In curved coordinates, the plate width direction is the X axis coordinate, and the plate thickness direction is the Y axis coordinate. And when the sensor 10 consists of the 1st sensor 10a and the 2nd sensor 10b, the X-axis coordinate will match with the 1st sensor 10a and the 2nd sensor 10b, and the Y-axis coordinate The zero point coincides with the first sensor 10a and the second sensor 10b.

(Manufacturing device, judgment device)

In the determination system 300, since the detail of the structure of the manufacturing apparatus 200 and the determination apparatus 1 (1A) is the same as the above, description is abbreviate | omitted.

The determination system 300 is provided with the determination apparatus 1 (1A) which determines the flux filling rate using the surface coordinates of the flux charging plate 101A measured immediately after the flux filling, so that the flux cross-sectional area is determined from the curve coordinates. Since the physical quantity directly related to the flux filling rate can be calculated, and the flux filling rate can be calculated and determined from the flux cross-sectional area, the calculation accuracy of the flux filling rate is increased, so that the accuracy of detecting the foreign material of the flux filling rate is excellent, and The productivity of the wire is also excellent.

It can be operated by a program (flux charge rate determination program) which functions as a flux charge rate calculation unit and a determination unit. Hereinafter, the flux filling rate determination program according to the present invention will be described.

As shown in Figs. 1, 5 (a) and (b), in the flux filling rate determination program of the present invention, the flux 102 is filled in the inside of the metal base plate 101 curved in the plate width direction. In order to determine the flux filling rate in the manufacturing apparatus 200 which manufactures the flux lead wire 101C by forming this metal plate 101 into a tubular shape, allowance of a predetermined metal slab mass, flux specific gravity, and flux filling rate is allowed.

And in the case of only the 1st sensor 10a, the curved surface coordinate measured will be a flux upper surface coordinate ZF (refer FIG. 2 (a)), and in the case of the 1st and 2nd sensors 10a and 10b, The measured surface coordinates are the flux top surface coordinates ZF and the metal plate outer surface coordinates ZMb (see FIG. 3A). In addition, the storage unit 3, in order to calculate the flux cross-sectional area in the flux cross-sectional area calculating unit 4, the metal plate inner surface coordinate ZMa (see FIG. 2 (a)) or the metal plate cross-sectional area S2 (FIG. 3). (b)] may be further memorized.

In the flux filling rate determination program, the configuration of the input unit 2, the flux cross-sectional area calculating unit 4, the flux filling rate calculating unit 5, the determining unit 6 and the display unit 7, and the storage unit 3 included in the computer The details of the configuration of) are the same as those of the determination apparatus 1 (1A), and thus description thereof is omitted.

Table 1 shows the results of the calculated flux filling rate.

It became. In addition, it was confirmed that by adding the correction value set by the preliminary experiment to the calculated filling rate, the flux filling rate closer to the flux filling rate of the product can be calculated with high accuracy.
