Description

Fixed roll alignment status detection and measurement system

[0001] The present invention relates to a fixed roll alignment status detection and measurement system, and more particularly, to a fixed roll alignment status detection and measurement system capable of detecting and measuring the alignment status of a measuring roll based on a measurement reference point in order to obtain information on the alignment status of the roll, i.e., the horizontality and parallelism of the roll itself, and wherein the system is fixedly installed on each measuring roll whose alignment status is to be detected and measured, so as to obtain real-time roll alignment status information, monitor the alignment status of each roll itself, and maintain and manage the alignment status of the entire roll processing line, thereby maximizing the sophistication and precision of the roll processing line.

[0002] Generally, it is used in the manufacturing process of steel products or films, etc.

[0003] Rolls are essential for various roll-to-roll processing (R2R) equipment, rolling mills, etc., and since these rolls have continuity from the entrance to the exit of each line in the factory, the alignment of the equipment is very important.

[0004] A roll in a film or rolling mill production line,

[0005] It serves to change the direction of the strip or to apply tension.

[0006] Therefore, if the roll alignment and level are not precisely performed based on the center line of the direction in which the strip is progressing, the product will experience a meandering phenomenon in which it is skewed to one side based on the center line of the direction in which the strip is progressing.

[0007] This ultimately causes problems such as wrinkles, waves, overlaps, and thickness deviations in the product, and causes the film to break during operation, which leads to production interruptions and lowers productivity.

[0008] Roll is,

[0009] As a consumable, it requires maintenance, such as repair and replacement, after a certain period of use, and due to the continuous nature of the line, it is managed according to strict standards to ensure optimal strip progression.

[0010] Therefore, a measuring device is required that can measure the alignment of the roll, i.e., the parallelism and horizontality of the roll, and correct them.

[0011] The present invention solves the problems of the past, and enables not only precise construction of a roll processing line, but also real-time roll alignment status monitoring even when the roll processing line is in operation.

[0012] The present invention aims to provide a fixed roll alignment status detection and measurement system that can maintain and manage the precision and sophistication of the roll alignment status (horizontalness and parallelism), thereby improving the durability, productivity, and efficiency of the roll processing line.

[0035] (Patent Document 2) (Document 2) Republic of Korea Patent Publication No. 10-1914942 (Registered on October 30, 2018)

[0036] Accordingly, the present invention has been devised to solve the above-mentioned conventional problems,

[0037] The purpose of this invention is to provide a fixed roll alignment status detection and measurement system that is formed and installed in a fixed manner on one side of both ends of a roll to detect the alignment status (horizontalness and parallelism) of the roll, so that the alignment status (horizontalness and parallelism) of each roll can be detected and monitored in real time not only when constructing a roll process line in which rolls are installed continuously, but also while the roll process line is in operation.

[0038] That is, the purpose is to provide a fixed roll alignment status detection and measurement system that can detect and measure the alignment status of a single roll in real time, rather than a method of measuring and detecting the alignment status between rolls (a method of detecting and measuring the alignment status of a roll whose alignment status is to be measured based on a roll that is a standard for measurement), thereby thoroughly detecting, maintaining, and managing the alignment status of a plurality of rolls forming a roll process line.

[0039] The present invention has been devised to achieve the above-mentioned purpose and to solve the problem,

[0040] In a fixed roll alignment status detection and measurement system,

[0041] The fixed roll alignment status detection and measurement system is

[0042] It is formed and installed in a fixed manner on one side of both ends of a roll formed in a roll process line to detect and measure the alignment status (horizontal and parallel).

[0043] To enable the alignment status (horizontalness and parallelism) of one roll to be detected and measured independently,

[0044] In real time, even while the roll process line is in operation,

[0045] By enabling detection and monitoring of the alignment status (horizontalness and parallelism) for the roll,

[0046] It is characterized by being able to thoroughly maintain and manage the alignment status (horizontalness and parallelism) of the roll.

[0048] In order for the rolls to be arranged and aligned on the roll process line to be positioned and fixed at a specific location, the roll bearing blocks formed at both ends of the rolls are installed and fixed on one side, respectively.

[0049] By allowing the roll to rotate without interference,

[0050] In order to initially build a roll process line, it is necessary to detect and measure the roll alignment status (horizontalness and parallelism), and also to detect and monitor the roll alignment status (horizontalness and parallelism) while the roll process line is in operation.

[0051] By processing the alignment status (horizontalness and parallelism) information detected and measured in real time from the roll,

[0052] A roll alignment status reading unit is configured to output information on the real-time alignment status (horizontalness and parallelism) of the roll and enable monitoring thereof.

[0053] Information on the alignment status (horizontalness and parallelism) of one or more rolls is output from the roll alignment status reading unit,

[0054] To enable the manager to intuitively recognize information about the real-time alignment status (horizontal and parallel) of each roll,

[0055] It is formed on one side of the roll bearing block that fixes the position of the roll,

[0056] A roll alignment state restoration correction unit is configured to correct the roll alignment state (horizontalness and parallelism) when the roll alignment state (horizontalness and parallelism) is outside a specific error range based on the real-time detected and measured alignment state (horizontalness and parallelism) information from the roll.

[0057] It is characterized by being able to thoroughly manage the alignment status (horizontalness and parallelism) of the roll.

[0058] Meanwhile, prior to this, the terms and words used in the patent registration claims of this specification should not be interpreted as limited to their usual or dictionary meanings, and should be interpreted as meanings and concepts that conform to the technical idea of ​​the present invention based on the principle that the inventor can appropriately define the concept of the term in order to explain his or her own invention in the best way.

[0059] Accordingly, the embodiments described in this specification and the configurations illustrated in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention, so it should be understood that there may be various equivalents and modified examples that can replace them at the time of filing this application.

[0060] As described above in the above configuration and operation, according to the present invention,

[0061] 1. It is possible to detect and measure the roll alignment status (horizontalness and parallelism) and monitor the roll alignment status (horizontalness and parallelism) not only when constructing a roll process line but also while the roll process line is in operation.

[0062] That is, the alignment status (horizontalness and parallelism) of rolls formed on the roll process line can be detected and monitored in real time.

[0063] 2. Since the roll alignment status (horizontalness and parallelism) can be detected and monitored in real time, it aims to improve the durability, productivity, and efficiency of the roll processing line.

[0064] 3. By detecting and monitoring the individual alignment status (horizontalness and parallelism) of a single roll in real time, rather than the relational alignment status between rolls, not only is detection and measurement, and alignment status correction easy, but all rolls whose real-time alignment status (horizontalness and parallelism) is being detected and measured can become the first roll that serves as the measurement standard, thereby maximizing the ease and precision of managing the alignment status (horizontalness and parallelism) of the entire roll process line.

[0065] 4. By synthesizing real-time information on the alignment status (horizontalness and parallelism) of each roll, a roll processing line can be built, allowing for a more sophisticated and precise roll processing line to be built and managed thoroughly.

[0066] That is, the present invention,

[0067] This is a very effective invention that maximizes the overall precision and ease of management of the roll processing line by enabling real-time detection and monitoring of the alignment status (horizontalness and parallelism) of each roll formed in the roll processing line.

[0095] By enabling detection and monitoring of the alignment status (horizontalness and parallelism) for the roll,

[0096] It is characterized by being able to thoroughly maintain and manage the alignment status (horizontalness and parallelism) of the roll.

[0097] That is, the present invention,

[0098] As mentioned above,

[0099] It is installed and formed in a fixed manner on one side of both ends of the roll,

[0100] Rather than measuring the relative alignment status (horizontalness and parallelism) between rolls, it is possible to detect and measure the alignment status (horizontalness and parallelism) of a single roll in real time.

[0101] By enabling detection and monitoring of the roll alignment status (horizontalness and parallelism) not only when constructing a roll process line but also when operating the roll process line,

[0102] This relates to a fixed roll alignment status detection and measurement system (1) that enables precise management of the roll alignment status (horizontalness and parallelism).

[0103] At this time, the fixed roll alignment status detection measurement system (1) is

[0107] In more detail,

[0108] The fixed roll alignment status detection and measurement system (1) is

[0109] A first roll alignment state detection unit (100) installed and fixed on one side of a roll bearing block (BB) formed at the end of a roll to detect and measure an alignment state (horizontal degree and parallel degree), generating an initial laser signal for detecting and measuring an alignment state (horizontal degree and parallel degree) for the roll, and transmitting a second laser signal (L2) for detecting and measuring an alignment state (horizontal degree and parallel degree) to a second roll alignment state detection unit (200) among the generated laser signals;

[0111] It is composed of a roll alignment status reading unit (300) that receives information on the alignment status (horizontalness and parallelism) of the roll detected and measured from the first roll alignment status detection unit (100) and the second roll alignment status detection unit (200), processes the received information, and outputs the processed information so that the manager can monitor it in real time.

[0112] It detects, measures, and monitors the alignment status (horizontalness and parallelism) of a single roll in real time, enabling thorough management of the roll alignment status (horizontalness and parallelism).

[0113] That is, the first roll alignment status detection unit (100) and the second roll alignment status detection unit (200)

[0114] Each roll is installed and fixed on a roll bearing block (BB) formed at each end of the roll to detect and measure the alignment status (horizontal and parallelism), and detects and measures the alignment status (horizontal and parallelism) of the roll by transmitting and receiving laser signals.

[0115] The roll alignment status reading unit (300) is

[0122] The second roll alignment status detection unit (200) is

[0123] It is composed of a reflection splitter laser receiving module (210) which is installed and fixed on one side of a roll bearing block (BB) formed at the other end of a roll to detect and measure the alignment state (horizontal degree and parallel degree), and is positioned symmetrically with the laser reflection splitter module (130) and in a straight line with the second laser signal (L2) transmitted from the laser reflection splitter module (130), and receives the second laser signal (L2) transmitted from the laser reflection splitter module (130), thereby obtaining information on the alignment state (horizontal degree and parallel degree) of the corresponding roll.

[0124] The alignment status (horizontalness and parallelism) of the other end of the roll can be detected and measured through the second laser signal (L2) transmitted from the laser reflection splitter module (130).

[0125] The roll alignment status reading unit (300) is

[0126] By processing the alignment status (horizontalness and parallelism) information detected and measured in real time from the roll,

[0127] Information on the real-time alignment status (horizontalness and parallelism) of the roll is output so that it can be monitored.

[0128] Information on the alignment status (horizontalness and parallelism) of one or more rolls is output from the roll alignment status reading unit (300),

[0146] By correcting the position of each roll bearing block (BB) formed at both ends of the roll, the position of the roll fixed to the roll bearing block (BB) is corrected.

[0147] The alignment status (horizontalness and parallelism) of rolls that are out of a certain error range can be corrected manually, semi-automatically or automatically by the administrator using various methods.

[0148] In addition, the fixed roll alignment status detection measurement system (1) is

[0149] When the real-time detection and measured roll alignment status (horizontalness and parallelism) is out of the normal range for the roll alignment status (horizontalness and parallelism) set by the administrator, the alignment status (horizontalness and parallelism) is judged to be defective, and an alignment status error range deviation alarm unit (500) is further included and configured so that the defective information can be transmitted to the administrator through at least one method among visual, auditory, and physical senses (vibration).

[0150] Allows the manager to immediately recognize any misalignment (horizontal and parallel) of the roll outside the normal range.

[0151] For reference, the roll bearing block (BB) described in the present invention is

[0152] Positioned and formed at each end of the roll,

[0153] It is a component that fixes the position of the roll while allowing the roll to rotate.

[0154] As described above, it is obvious to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention.

[0155] Accordingly, since the present invention can be implemented in various other forms without departing from the technical idea or main characteristics, the embodiments of the present invention are merely examples in all respects and should not be construed as limiting, and can be implemented in various modified forms. Hereinafter, with reference to the attached drawings, the functions, configuration, and operation of the fixed roll alignment state detection and measurement system (1) of the present invention will be described in detail.

[0214] By correcting the position of each roll bearing block (BB) formed at both ends of the roll, the position of the roll fixed to the roll bearing block (BB) is corrected.

[0215] The alignment status (horizontalness and parallelism) of rolls that are out of a certain error range can be corrected manually, semi-automatically or automatically by the administrator using various methods.

[0216] In addition, the fixed roll alignment status detection measurement system (1) is

[0217] When the real-time detection and measured roll alignment status (horizontalness and parallelism) is out of the normal range for the roll alignment status (horizontalness and parallelism) set by the administrator, the alignment status (horizontalness and parallelism) is judged to be defective, and an alignment status error range deviation alarm unit (500) is further included and configured so that the defective information can be transmitted to the administrator through at least one method among visual, auditory, and physical senses (vibration).

[0218] Allows the manager to immediately recognize any misalignment (horizontal and parallel) of the roll outside the normal range.
