Next, an embodiment of the present invention will be described with reference to the drawings.
(Transport system)
The load inspection apparatus according to an embodiment of the present invention is provided in an electrolytic copper transport system. First, the transport system will be described.
The electrolytic copper obtained by electrolytic refining or electrolytic collection of copper is packed and shipped for shipping by the transport system S shown in FIG. The transport system S includes a packing apparatus 1 that stacks plate-shaped electrolytic copper to form a load pile L. The dimensions of the electrolytic copper are not particularly limited, and are, for example, a length of 1,050 mm, a width of 1,050 mm, and a thickness of 20-30 mm. Ten or more, for example, 14 pieces of this electrolytic copper are stacked to form a load mountain L. The average height of the cargo mountain L is 2,800 to 3,000 mm, and the weight is 2,600 to 2,900 kg.

  A conveying device 2 such as a chain conveyor or a belt conveyor is connected to the packing device 1, and the load mountain L is conveyed by the conveying device 2. The conveying path of the load mountain L is provided with a weighing device 3 for monitoring the load mountain L and a printing device 4 for printing product information on the load mountain L. The transport device 2 is configured to repeat transport and stop at every predetermined transport distance, and the load mine L is temporarily stopped at the position of the observing device 3 and the printing device 4.

  As the appraisal device 3, for example, a device that is provided below the transfer surface of the transfer device 2 and lifts the load mountain L with a cylinder and uses it is used. The load weight measured by the observing device 3 is input to the product information input / output device 5 and transmitted from the product information input / output device 5 to the product management system 6 to be recorded.

  The printing device 4 is provided with an ink jet type print head and the like, and prints product information on the cargo pile L. Product information includes the date of copper production, the number of copper production, the number of copper sheets constituting the cargo pile L, the weight of the cargo pile, and the like. Such product information is recorded in the product management system 6 and is input from the product management system 6 to the printing device 4 via the product information input / output device 5.

  The printing device 4 is provided with height sensors 41 that measure the heights of the four corners of the load mountain L. As the height sensor 41, for example, an ultrasonic distance meter is used. As shown in FIG. 2, the ultrasonic distance meter 41 is fixed above the load mountain L so as to face the four corners thereof. The distance to the upper surface of the load mountain L is measured by the ultrasonic distance meter 41, and the heights of the four corners of the load mountain L are measured by subtracting the measured value from the height of the ultrasonic distance meter 41 from the transfer device 2. it can.

  By measuring the heights of the four corners of the load mountain L with the height sensor 41, the inclination of the upper surface of the load mountain L can be calculated. Considering this inclination, the print quality can be improved by bringing the print head closer to the upper surface of the load L. The heights of the four corners of the cargo pile L measured by the height sensor 41 are input to the product information input / output device 5 and input from the product information input / output device 5 to the product management system 6.

  The load mountain L on which the product information is printed by the printing device 4 is transported to the load storage position at the end of the transport device 2. Then, after being loaded onto a heavy machine such as a forklift, it is transported to a product storage location or the like.

  In some cases, electrolytic copper obtained by electrolytic refining or electrowinning of copper may include poorly shaped electrolytic copper, such as electrolytic copper in which metal particles are formed or strained electrolytic copper. The load pile L containing poorly shaped electrolytic copper may become unstable and cause collapse of the load during the transfer process by the transfer system S. The load collapse of the load mountain L mainly occurs in the transport direction. This is because guides can be provided on both sides of the transport device 2 and load collapse in the direction perpendicular to the transport direction can be prevented. As described above, the weighing device 3 lifts the load mountain L with a cylinder and looks at it. At this time, if the load mountain L is collapsed, the measured value becomes heavier than the actual weight because, for example, the electrolytic copper is caught on the adjacent load mountain L, which causes a weight error. Moreover, since the upper surface of the load mountain L is greatly inclined, the print quality is deteriorated. For this reason, the load mountain L that has collapsed cannot be shipped as a product.

  In addition, poorly shaped electrolytic copper cannot be shipped as a product in terms of appearance quality. If the loaded mountain L includes poorly shaped electrolytic copper, a gap is formed between the electrolytic copper and the electrolytic copper, and the filling rate of the loaded mountain L is lowered. For this reason, by detecting an abnormality in the filling rate, it is possible to inspect the load pile L even though poorly shaped electrolytic copper is included.

(Kazan inspection equipment)
Next, the loading inspection apparatus A according to the present embodiment will be described. The load-carrying inspection apparatus A includes (1) a load collapse detection unit that detects a load collapse of the load mountain L, and (2) a filling rate abnormality detection unit that detects a filling rate abnormality of the load mountain L. Hereinafter, it demonstrates in order.

(1) Load collapse detection means As shown in FIG. 1, the load collapse detection means includes a pair of detection sensors 7 and 7 (7a, 7b) provided in the transport path of the load mountain L and the product information input / output device 5. The load collapse determination unit 51 realized in the above. The pair of detection sensors 7 and 7 are provided at two positions that are separated from each other by a predetermined dimension in the conveying direction of the load mountain L with the observing device 3 interposed therebetween. Here, the specified dimension is set to a dimension that can detect the collapse of the load mountain L. For example, it is set as 110% of the dimension in the transport direction of electrolytic copper.

  The detection sensor 7 is a sensor that detects the presence or absence of a load mountain L at a specific position on the conveyance path, and for example, an area sensor is used. As shown in FIG. 2, the area sensor 7 includes a light emitting unit 7a and a light receiving unit 7b. The light from the light emitting portion 7a is received by the light receiving portion 7b, and the presence or absence of the load mountain L is detected by the light being blocked by the load mountain L. The light emitting unit 7a and the light receiving unit 7b of the area sensor 7 are provided to face each other with the conveying device 2 interposed therebetween, and the detection surfaces thereof are arranged so as to be orthogonal to the conveying direction of the cargo pile L.

  When the load mountain L reaches the observing device 3, it is temporarily stopped and is admitted by the observing device 3. The transport device 2 is provided with a control device that controls its operation, and the observing device 3 is configured to detect that the transport device 2 has been temporarily stopped by the control device. In addition, a loading sensor (not shown) that detects the presence or absence of a load mountain L at the position of the weighing device 3 is provided in the vicinity of the weighing device 3. When the observing device 3 detects both the temporary stop of the conveying device 2 and the presence of the load mountain L by the load sensor, the load device L looks at the load mountain L. In addition, for example, a diffuse reflection type phototube is used as the in-stock sensor, and is provided near the center in the width direction of the transport device 2 to detect the presence or absence of the load mountain L from below the transport surface.

  If the load mountain L on the weighing device 3 is collapsed in the transport direction at this time, the dimension of the load mountain L in the transport direction exceeds the specified dimension, so one or both of the pair of detection sensors 7 and 7 Is in a state where the load mountain L is detected.

  Detection signals of the detection sensors 7 and 7 are input to the product information input / output device 5. The product information input / output device 5 is configured by a computer or the like, and a load collapse determination unit 51 is realized by executing a program or the like. The load collapse determination unit 51 determines that the load mountain L is collapsed when one or both of the pair of detection sensors 7 and 7 detect at the time of appraisal.

As described above, the load collapse detection means can automatically inspect the load collapse of the load mountain by detecting whether or not the size of the load mountain L in the transport direction exceeds the specified size.
Moreover, since the load collapse of the load mountain L is determined using the detection sensors 7 and 7 provided across the weighing device 3, it is possible to detect the load collapse at the time of loading, and to ensure the error in the weight value due to the load collapse. Can be detected.

(2) Filling Rate Abnormality Detection Unit The filling rate abnormality detection unit includes a height sensor 41 provided in the printing apparatus 4 and a filling rate abnormality determination unit 61 realized by the product management system 6. As described above, the height sensor 41 measures the heights of the four corners of the load mountain L, and the measurement results are input to the product management system 6 via the product information input / output device 5. In addition, the load weight measured by the observing device 3 is also input to the product management system 6 via the product information input / output device 5.

  In the present embodiment, the height sensor that constitutes the filling rate abnormality detection unit is the same as the height sensor 41 of the printing apparatus 4, but separate sensors may be provided. As a height sensor constituting the filling rate abnormality detection means, it is only necessary to measure the heights of the four corners of the load mountain L, and various sensors can be used in addition to the ultrasonic distance meter.

The product management system 6 is configured by a computer or the like, and a filling rate abnormality determination unit 61 is realized by executing a program or the like. The filling rate abnormality determination unit 61 calculates the filling rate of the load mountain L from the measured value of the measuring device 3 and the measured value of the height sensor 41. For example, the loading ratio is W [kg] for the load mountain weight, h1 to h4 [m] for the heights of the four corners of the load mountain L, d for the specific gravity of the load mountain L, and S for the average surface area of electrolytic copper. m ² ] is calculated by the following formula 1. Here, the specific gravity d of the load mountain L is 8.96 × 10 ⁻³ kg / m ³ . Thus, the filling rate of the load mountain L can be calculated by a simple method using the observing device 3 and the height sensor 41.
(Equation 1)
Filling rate [%] = W / {d ・ S ・ (h1 + h2 + h3 + h4) / 4}

  Next, the filling rate abnormality determining unit 61 determines that the load L is a filling rate abnormality when the filling rate is outside the specified range. Here, the upper limit and the lower limit of the specified range are determined with a certain range on the basis of the filling rate of the normal load mountain L. When the calculated filling rate is less than the lower limit of the specified range, the load mountain L contains poorly shaped electrolytic copper, and there is a gap between the copper and the copper electrode so that the filling rate of the load mountain L is low. It is thought that it has become. Further, when the calculated filling rate exceeds the upper limit of the specified range, it is considered that the load mountain L causes the collapse of the load and the weight of the load mountain measured by the observing device 3 is heavier than the actual weight.

  As described above, by detecting whether or not the filling rate of the load mountain L is within the specified range by the filling rate abnormality detection means, the load mountain contains defective shaped copper, and the load collapse of the load mountain. Can be automatically inspected.

  An alarm device 8 such as a rotating lamp is connected to the product information input / output device 5. The alarm device 8 is disposed at the load loading position at the end of the transport device 2. When the load collapse determination unit 51 determines that the load collapses or the filling rate abnormality determination unit 61 determines that the filling rate is abnormal, the alarm device 8 notifies the worker that the load mountain L is defective. An operator collects defective loads and prevents them from being shipped as products.

  In this way, since the defective load can be automatically detected, the work burden on the worker can be reduced. Moreover, since visual confirmation of an operator is unnecessary, the conveyance speed of the load mountain L can be made quick and production efficiency can be improved.

(Other embodiments)
In the above embodiment, the load collapse determination unit 51 is realized by the product information input / output device 5 and the filling rate abnormality determination unit 61 is realized by the product management system 6, but these are realized by using other control devices. May be.

  Moreover, you may comprise the detection sensor 7 of a load collapse detection means only with one unit. One detection sensor 7 is installed on the transport path of the load carrier L, and the dimension of the load mountain L in the transport direction is obtained from the transport speed of the transport device 2 and the time required to pass the detection sensor 7. Can do. What is necessary is just to judge the load collapse of the load mountain L by detecting whether the calculated | required dimension exceeds a regulation dimension.

  Moreover, as a load mountain inspection apparatus, it is good also as a structure which has only any one of said (1) load collapse detection means and (2) filling rate abnormality detection means.
