Description

[Detailed description of the invention]

[0001]

[Technical field of invention]

 The present invention is capable of measuring the height of each silo installed in a factory or the like quickly and without leak, and accurately grasping the remaining amount of the stored silo stored in each silo. Relating to a remaining amount grasping device.

[0002]

[Prior art]

 In a factory where a large number of silos are installed and powders, liquids, and other stored materials are stored in each silo, an appropriate amount of each silo is stored at an appropriate time as needed during daily production activities. When goods are dispensed or when it is visually recognized that they are in short supply, provisions are made to replenish the stored items in silos from transportation means such as trucks.

By the way, in order to grasp the balance of business activities for a certain period of time at any factory, inventory is carried out on a predetermined closing date, but at this time, in order to minimize the error, all the silos installed are It is necessary to know the actual remaining amount of the stored items stored in the area during the specified closing date.

In order to make such a grasp, as a measure generally used in the past, as shown in FIG. 19, one operator (M1) is a long measure with a weight (a) attached to the tip. Using (b), the omori (a) is brought into contact with the measurement point (e) on the surface of the remaining storage (d) in the silo (c), and the measurement point (e) and the top of the silo (c) The height to the storage level position (F) is measured with the measurer (B) to measure the air height (G) and the measured value is read aloud, and the other worker (M2) reads the read air height. A pair of people who took a work procedure such as recording the measurement value of (G) measured the air heights of many installed silos one after another and recorded the measurement value.

Since the cross-sectional area value of each installed silo is known, the volume of the empty area can be calculated by actually measuring the height of each silo, and the empty area can be calculated from the total volume of the silo. By multiplying the volume obtained by removing the volume of the product by the specific gravity of the stored product, the actual remaining amount of the stored product in the silo can be determined.

[0006]

[Problems to be solved by the device]

 However, in the above-mentioned measurement method by a pair of people, a long measure (b) must be rolled up after the measurement is completed, moved to the next measurement silo, and again the appropriate length must be measured. It takes time to measure the height (g) because careful work is required to prevent the weight (a) from being buried in the storage. On the other hand, silos that store powders, liquids, etc. are usually installed in the factory building, with tens to hundreds of dense silos. For this reason, it is very hard work to measure the height of all the silos installed in a given day without leaks. Leakage may occur.

Further, in the vicinity of the silo, operating noises of various machines are generated and the noise is intense, and the above-mentioned worker (M1) can accurately read out the measurement value of the sky height for other work. Since it was not transmitted to the person (M2), incorrect measurement values were often recorded. Furthermore, in addition to these problems, it is difficult to grasp the exact actual amount of storage in all installed silos due to the severe work of extreme heat and cold due to the environmental conditions in which the silos are installed. Inevitably, the inventory was inaccurate.

At this time, as shown in FIGS. 13, 14 and 17, when the measurement / print start instruction keyboard 77 and the print instruction keyboard 81 are pushed down, the printer unit is pressed. 85 operates, as shown in FIG. 18, the air height measurement data relating to the silo having the one management number stored in the air height data memory means is taken out, and the output data is output. Print the control number of one silo on the silo control number print area 88A of the system 88 and the sky height measurement value on the sky height measurement value print area 88B. To be done. Next, when the measurement end / print stop instructing keyboard 79 is pushed down, the above-mentioned measurement and printing operations are stopped, and one execution cycle for measuring the height and printing is completed.

After that, the operations from the input of the control number of the silo to be measured to the printing of the air height measurement data are sequentially repeated for the silo of the one control number and the silo of the other control number. Then, the empty height is measured for each silo control number, and the measurement silo instruction / measurement information retrieval means is required to grasp the remaining amount of the stored items stored in the many silos installed. The memory of the height measurement data by 89 and the above-mentioned printing on the recording paper 87 are executed.

If an appropriate communication cable connected to an upper management computer (not shown) is connected to the management computer interface unit 71, the operator M measures. The air height measurement data for each control number of the silo is instantaneously transmitted to the upper management computer via the interface cable 91 and the measurement silo instruction / measurement information extracting means 89 in sequence. The remaining amount of stored material in each of the many installed silos is comprehensively grasped by the superordinate management computer.

[Effect of the invention]

 Since the present invention is constructed as described in detail above, it has the following excellent effects. According to the invention of claim (1), the management number of the silo to be sequentially measured can be input and visually confirmed before the measurement of the sky height, so that the silo can be stored in many silos within a short time. Even if it is necessary to know the remaining amount of stored materials, measurement omission does not occur. In addition, the measurement point on the surface of the stored material is determined and confirmed using a laser with a visible wavelength, and the distance between the measurement point and the measurement device is measured by measuring the sky height from one round trip time of ultrasonic waves. Since the configuration is adopted, it is possible to quickly and accurately measure the height of the sky. Further, since the device for measuring the height of the sky is configured so that the means for storing the measurement data is detachably connected via the measurement side interface part, the residual quantity grasping device for the silo storage is obtained. Since the measurement data can be instantly stored in memory, no operator is required to record the measurement results, and only one operator can quickly and accurately install all the silo storage materials. It is possible to measure the height of the sky and record the measurement results, which are necessary for grasping the remaining amount of air.

On the other hand, according to the invention of claim (2), the components for measuring the height of the sky, the memory of the height of the sky, the output of the measurement data, and the structure capable of being transmitted to the upper computer. Since the device for collecting remaining amount of silo stored in a compact and detachable connection with the elements was used, only one worker can quickly and accurately install the stored items in all silos. Measurement of air height necessary for grasping the remaining amount, recording of measurement results, confirmation of output of measurement data as appropriate, and transmission of the measurement data to the upper-level computer be able to. In addition, since the configuration is such that it can be transmitted to a high-level computer, it is of a higher level, in which the grasp and management of the stored items in many silos are judged based on the operation of the entire factory. Integrated management.
