The origin detection unit 475c detects the image data of the small lid by detecting the image data having the maximum correlation value with all the image data D. At this time, the origin detection unit 475c may gradually increase the data from the pattern image data E in the detection process so that it finally becomes the entire image data D.

  The origin detection unit 475c has a function of detecting (calculating) position data of the small lid 122 in the image data from the detected image data of the small lid 122 as a second function. Specifically, the origin detection unit 475c detects the position data (X coordinate and Y coordinate) of the image data of the small lid with respect to the acquired image data F in units of pixels. More specifically, the origin detection unit 475c detects position data at the reference position of the small lid (for example, the center of the nut at the center) in units of pixels.

  The origin detection unit 475c has a function of detecting (calculating) the position of the small lid 122 relative to the imaging unit 475b from the position data of the small lid in the detected image data as a third function. Specifically, since the distance between the extruder-side furnace lid 12 and the cleaning device main body 471 is constant by the distance detection unit 475d, the origin detection unit 475c performs cleaning from the position data of the small lid in the detected image data. The position of the small lid 122 with respect to the apparatus main body 471 (the mobile device 476) is detected.

  Furthermore, the origin detection unit 475c has a function of detecting (calculating) the origin of the cleaning work start from the position of the small lid 122 with respect to the detected imaging unit 475 as a fourth function. Specifically, the origin detection unit 475c detects the origin of the cleaning work start determined from the reference position in the small lid 122, that is, a predetermined position with respect to the reference position.

  The distance detection unit 475d is disposed inside the cubicle 475a and at substantially the same level (height) as the small lid 122. Specifically, the distance detector 475d employs a laser distance measurement method.

  The moving means 476 includes an industrial robot 476a that moves the nozzle portion 473a and the blade portion 474a, and a connecting portion 476b that is disposed at the tip of the industrial robot 476a and connects the nozzle portion 473a and the blade portion 474a.

  The industrial robot 476a has 4 degrees of freedom. Specifically, the industrial robot 476a has three degrees of freedom for moving the nozzle portion 473a and the blade portion 474a in three dimensions, a state of cleaning with the water cleaning means 473, and a state of cleaning with the blade cleaning means 474. And 1 degree of freedom for switching. The industrial robot 476a is housed in a casing 476c that is hermetically sealed and is positively pressurized in order to prevent dust, water and heat.

  The connecting portion 476b is configured such that the base end portion is fixed to the industrial robot 476a and the nozzle portion 473a and the blade portion 474a are fixed to the tip end portion so as to be rotatable around the base end portion. Specifically, the connecting portion 476b is formed in an L-shaped plate shape in plan view, and the direction in which the nozzle portion 473a ejects high-pressure water and the direction in which the long blade portion 474a extends are orthogonal to each other. Thus, the nozzle part 473a and the blade part 474a are connected.

  When the connecting portion 476b switches between the state of cleaning with the water cleaning means 473 and the state of cleaning with the blade cleaning means 474, the connecting portion 476b is rotated 90 degrees along the horizontal direction around the base end by the industrial robot 476a. It is rotated. Moreover, the connection part 476b fixes the nozzle part 473a to the upper side formed in plate shape along a horizontal direction, and has fixed the blade part 474a to the downward side.

  The configurations of the coke oven extruder 4 and the small lid cleaning device 47 according to this embodiment are as described above. Next, regarding the coke extrusion process of the coke oven extruder 4 according to this embodiment, the flow shown in FIG. Take this into account.

  The coke extrusion process of the coke oven extruder 4 is repeatedly performed on the plurality of carbonization chambers 10. The carbonization chamber 10 having the small lid 122 cleaned by the small lid cleaning device 47 at the time of the immediately preceding coke extruding process is subjected to the other end of the coke that has been carbonized by the extrusion ram 42 at the time of the coke extruding process. Extruded to the side. In addition, since the carbonization chamber 10 in which the coke that has been carbonized is pushed out to the other end side by the extrusion ram 42 during the immediately preceding coke extrusion process is being charged with coal by the charging vehicle 2, In this case, the level of coal is leveled by the leveler 43.

  Therefore, when the coke extrusion process of the predetermined carbonization chamber 10 is completed, the guide wheel 3 is moved by five in the width direction of the carbonization chamber 10 by the guide wheel main body 31, and the extruder 4 is similarly an extruder. The main body 41 moves five chambers in the width direction of the carbonization chamber 10. When the guide wheel 3 and the extruder 4 are arranged at predetermined positions, in a predetermined carbonization chamber 10 (referred to as “carbonization chamber M” in FIG. 12), the guide vehicle furnace lid attaching / detaching device 32 is connected to the guide vehicle side furnace cover. 13 and the extruder furnace lid attaching / detaching device 44 starts removing the extruder side furnace lid 12.

  At this time, in the carbonization chamber 10 adjacent to the left five from the carbonization chamber M as viewed from the extruder 4 side (referred to as “carbonization chamber L” in FIG. 12), the small lid cleaning device 47 starts cleaning, In the carbonization chamber 10 right next to the carbonization chamber M (referred to as “carbonization chamber R” in FIG. 12), the leveler 43 starts leveling the coal level. In the carbonization chamber L, since the water cleaning means 473 can supply high-pressure water from the high-pressure water supply device 46, the water cleaning means 473 jets the high-pressure water to clean the small lid 122.

  Thereafter, in the carbonization chamber M, when the furnace lid attaching / detaching devices 32 and 44 remove the furnace lids 13 and 12, after the guide way 33 of the guide wheel 3 is attached, the extrusion ram 42 of the extruder 4 carbonizes the carbonized coke. While pushing out toward the other end side of the chamber 10, the furnace lid cleaning device 45 injects the high-pressure water supplied from the high-pressure water supply device 46 and starts cleaning the extruder-side furnace lid 12.

  At this time, in the carbonization chamber L, when the furnace lid cleaning device 45 cleans the extruder side furnace lid 12, the water cleaning means 473 is stopped from supplying high-pressure water. The blade cleaning means 474 that does not require high-pressure water is switched so as to clean the small lid 122. In the carbonization chamber R, the leveler 43 completes the coal leveling in the carbonization chamber 10.

  After that, in the carbonization chamber M, when the furnace cover cleaning device 45 completes cleaning of the extruder side furnace cover 12, the frame cleaning device 48 cleans the frame 14, and when this is completed, the tar pan cleaning device 49 converts the tar pan 15 To clean. Further, when it is completed, the extruder furnace lid attaching / detaching device 44 attaches the extruder side furnace lid 12.

  At this time, in the carbonization chamber L, since the furnace cleaning device 45 can complete the cleaning of the extruder side furnace lid 12, the water cleaning means 473 can supply high pressure water from the high pressure water supply device 46. The lid cleaning device 47 switches so that the water cleaning means 473 cleans the small lid 122. Then, the water cleaning means 473 continues to clean the small lid 122 until the extruder furnace lid attaching / detaching device 44 completes the attachment of the extruder side furnace lid 12.

  When the extruder furnace lid attaching / detaching device 44 completes the attachment of the extruder side furnace lid 12, the water cleaning means 473 completes the cleaning of the small lid 122, so that one step of the coke extrusion process (in FIG. 12) 1 step is completed (349 seconds), and the next coke extrusion step is started. That is, the guide wheel 3 is moved by the guide wheel main body 31 by five chambers in the width direction of the carbonization chamber 10, and the extruder 4 is similarly moved in the width direction of the carbonization chamber 10 by the extruder main body 41. Move minutes.

  As described above, in the coke oven extruder 4 according to the present embodiment, the imaging unit 475b images the small lid 122, and the origin detection unit 475c detects the origin of the cleaning work start from the image data acquired by the imaging unit 475b. The small lid opening / closing means 472 opens the small lid 122, and the water cleaning means 473 sprays high-pressure water from the nozzle portion 473a toward the cleaning target area of the small lid 122, whereby the cleaning target area can be cleaned.

  At this time, since the nozzle unit 473a moves based on the movement data stored from the origin detected by the origin detection unit 475c, the small lid cleaning device 47 can detect the origin of the cleaning operation accurately and The small lid 122 can be cleaned, and as a result, the small lid 122 and the surrounding area to be cleaned can be accurately cleaned.

  Moreover, since the coke oven extruder 4 which concerns on this embodiment can switch the state cleaned with the water cleaning means 473, and the state cleaned with the blade cleaning means 474, the blade cleaning means 474 of the small lid | cover 122 can be switched. The site to be cleaned can be cleaned by bringing the blade portion 474a into contact with the site to be cleaned.

  At this time, since the blade part 474a connected to the nozzle part 473a moves based on the origin detected by the origin detection part 475c similarly to the nozzle part 473a, after accurately detecting the origin of the cleaning operation, The small lid 122 can be cleaned not only by the water cleaning means 473 but also by the blade cleaning means 474. In addition, since the origin of the cleaning work start of the water cleaning means 473 is also used as the origin of the cleaning work start of the blade cleaning means 474, the small lid 122 can be efficiently cleaned.

  Further, for example, in a conventional small lid cleaning device that detects the origin of work start by direct contact detection, the origin of the start of cleaning work cannot be accurately detected, so the blade portion contacts the inner surface of the small lid mouth portion 121a. As a result, the blade portion is often damaged, and it is difficult to attach it to an industrial robot.

  On the other hand, in the small lid cleaning device 47 according to the present embodiment, the origin of the cleaning operation start can be accurately detected, that is, the accuracy of the origin detection can be improved, so that the blade portion 474a is connected to the small lid mouth portion. It can be moved from each inner surface of 121a at regular intervals, and the blade portion 474a can be attached to the industrial robot 476a.

  Further, in the coke oven extruder 4 according to this embodiment, the origin detection unit 475c detects the image data of the small lid from the image data F acquired by the imaging unit 475b, and the image data F is detected from the detected image data of the small lid. The position data of the small lid is detected. Then, the position of the small lid 122 relative to the imaging unit 475b is detected from the position data of the small lid in the image data detected by the origin detection unit 475c, and the origin of the cleaning operation start is detected from the detected position of the small lid 122. Therefore, the origin of the cleaning work start can be accurately detected.

  Further, in the coke oven extruder 4 according to this embodiment, the industrial robot 476a having at least 4 degrees of freedom can move the nozzle part 473a and the blade part 474a with 3 degrees of freedom, and with 1 degree of freedom. The state of cleaning with the water cleaning means 473 and the state of cleaning with the blade cleaning means 474 can be switched.

  Therefore, for example, the nozzle part 473a and the blade part 474a can be moved smoothly and accurately, and the movement of the nozzle part 473a and the blade part 474a can be flexibly handled. Furthermore, for example, the installation space of the moving means 476 can be reduced.

  Further, the coke oven extruder 4 according to the present embodiment injects high-pressure water from a plurality of locations so that the nozzle portions 473a are parallel to each other, and rotates around the direction in which the nozzle portions 473a inject high-pressure water. The high-pressure water can be efficiently ejected onto the desired site to be cleaned.

  For example, a conventional small lid cleaning device injects high-pressure water from a plurality of locations so that the nozzle portion expands in order to cope with a case where the starting point of the cleaning operation is slightly erroneously detected (Patent Document 1). Therefore, in order to prevent high-pressure water from entering the small lid opening 121a (carbonization chamber 10) and quenching and damaging the small lid opening 121a (carbonization chamber 10), the small lid 122 is used. It was necessary to arrange a high-pressure water intrusion prevention lid (see reference numeral 25 of Patent Document 1) at the position where the was removed.

  In contrast, in the small lid cleaning device 47 according to the present embodiment, since the nozzle portion 473a can inject high-pressure water to a desired cleaning target site after the origin of the cleaning operation is accurately detected, It is possible to reliably prevent entry into the small lid opening 121a (carbonization chamber 10), and as a result, it is possible to omit the high-pressure water ingress prevention lid.

  Further, in the coke oven extruder 4 according to the present embodiment, in the coke extrusion process, after the extruder furnace lid attaching / detaching device 44 removes the extruder side furnace lid 12, the furnace lid cleaning device 45 is operated on the extruder side furnace lid. Cleaning of the extruder-side furnace lid 12 is started by injecting high-pressure water toward the 12 cleaning target parts. Then, after the furnace lid cleaning device 45 completes the cleaning of the extruder side furnace lid 12, the installation of the extruder side furnace lid 12 removed by the extruder furnace lid attaching / detaching device 44 is started.

  On the other hand, since the high pressure water supply device 46 can be switched between a state in which high pressure water is supplied to the furnace lid cleaning device 45 and a state in which high pressure water is supplied to the small lid cleaning device 47, the furnace lid cleaning device 45 is an extruder. Before and after the cleaning of the side furnace lid 12 is started, the water cleaning means 473 of the small lid cleaning device 47 can spray the high pressure water to clean the small lid 122.

  In addition, since the small lid cleaning device 47 can be switched between the state of cleaning with the water cleaning means 473 and the state of cleaning with the blade cleaning means 474, when the furnace lid cleaning device 45 cleans the extruder side furnace lid 12. The cleaning target part can also be cleaned by bringing the blade portion 474a into contact with the small lid 122 and the cleaning target part around it.

  Here, in the coke extrusion process according to the present embodiment, (1) moving work by the extruder body 41, (2) furnace cover removal work by the furnace cover attaching / detaching device 44, (3) coke extrusion work by the extrusion ram 42, (4) Furnace cleaning work by the furnace cover cleaning device 45, (5) Frame cleaning work by the frame cleaning device 48, (6) Tar pan cleaning work by the tar pan cleaning device 49, (7) Furnace attachment by the furnace lid attaching / detaching device 44 Seven of the tasks are essential tasks.

  Further, the time required for the essential seven operations (in this embodiment, 349 seconds) is not extended, and the cleaning time with the high-pressure water of the small lid cleaning device 47 can be sufficiently secured. Since the blade cleaning means 474 cleans the small lid 122 during the time period when the cleaning means 473 cannot clean the small lid 122, the small lid 122 can be efficiently cleaned while preventing a decrease in production efficiency.

  Further, since it is not necessary for the high-pressure water supply device 46 to supply high-pressure water to the furnace lid cleaning device 45 and the small lid cleaning device 47 at the same time, the capability of the high-pressure water supply device 46 can be increased to the furnace lid cleaning device 45 or the small lid cleaning device. The size can be reduced to the extent that the larger one of 47 is satisfied. For example, the cost can be reduced and the installation space can be reduced.

  The small lid cleaning device and the coke oven extruder according to the present invention are not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention. .

  For example, in the coke oven extruder according to the present invention, the water cleaning means 473 sprays high-pressure water into the small lid part 121a (in the carbonization chamber 10), thereby rapidly cooling the small lid part 121a (the carbonization chamber 10). In order to reliably prevent damage, a configuration in which a high-pressure water intrusion prevention lid can be disposed at a position where the small lid 122 is removed may be employed.

  In addition, the small lid cleaning device 47 according to the present invention detects an external force when a necessary (set) external force is applied to the blade portion 474a in order to prevent damage to the blade portion 474a of the blade cleaning means 474. The blade damage prevention means for stopping the cleaning work by the blade portion 474a may be provided.

  For example, the blade damage prevention means may be configured to stop the rotation of the blade portion 474a when a torque greater than a set value is generated in the rotating blade portion 474a. In the form, it may be configured to be separated from each inner surface of the small lid part 121a, that is, the movement path (movement data) of the blade part 474a may be corrected.

  Further, in the coke oven extruder 4 according to the above-described embodiment, the leveler 43 equalizes the level of coal in the carbonizing chamber 10 adjacent to the five chambers on the right side with respect to the carbonizing chamber 10 where the extrusion ram 42 extrudes coke. The case where the lid cleaning device 47 cleans the small lid 122 of the carbonization chamber 10 adjacent to the five chambers on the left side has been described. However, the present invention is not limited to such a case. Or you may.

  In short, the carbonization chamber 10 having the small lid 122 cleaned by the small lid cleaning device 47 in the immediately preceding coke extruding step is used for the coke extruding step of the carbonized coke to the other end side by the extrusion ram 42. Extruded. In other words, the small lid cleaning device 47 cleans the small lid 122 associated with the carbonization chamber 10 that pushes the coke that has been carbonized to the other end side by the extrusion ram 42 during the next coke extrusion process.

  Further, in the coke oven extruder 4 according to the above-described embodiment, the carbonizing chamber 10 in which the leveler 43 leveles the coal and the carbonizing chamber 10 in which the small lid cleaning device 47 cleans the small lid 122 include an extrusion ram. Although the case where 42 is a position symmetrical with respect to the width direction with respect to the carbonization chamber 10 that extrudes coke has been described, the present invention is not limited thereto.

  For example, the carbonization chamber 10 in which the small lid cleaning device cleans the small lid 122 and the carbonization chamber 10 in which the leveler equalizes the level of coal may be the same. According to this configuration, the small lid opening / closing means in the small lid cleaning device and the small lid opening / closing means in the leveler can be shared.

  Further, in the small lid cleaning device 47 according to the above embodiment, the case of cleaning the small lid 122 that can be rotated 180 degrees has been described. However, the present invention is not limited to this case. For example, the small lid cleaning device 47 may clean a small lid that can be rotated 180 degrees or less or 180 degrees or more.

  Here, for example, when the small lid cleaning device 47 cleans a small lid that can be rotated at an angle of less than 180 degrees, specifically, the flat small lid and the flat small lid mouth portion intersect each other. First, the nozzle portion 473a and the blade portion 474a can be moved in three axis directions (X axis, Y axis, Z axis) with a degree of freedom of 3.

  The small lid cleaning device 47 switches between the state of cleaning with the water cleaning means 473 and the state of cleaning with the blade cleaning means 474, with the remaining degree of freedom 1, and the flat small lid and the flat small size. It is configured to be able to switch (turn) so that the direction of water sprayed from the nozzle portion 473a (the extending direction of the long blade portion 474a) is orthogonal to the small lid and the small lid mouth portion with respect to the lid mouth portion. Is done.

  Further, in the small lid cleaning device 47 according to the above embodiment, the small lid opening seal part 121b, the gas passage forming part 122a and the knife edge 122b are cleaned by the water cleaning means 473, and the small lid is cleaned by the blade cleaning means 474. Although the case where each inner surface of the mouth part 121a is cleaned has been described, the present invention is not limited to such a case, and the site to be cleaned by the small lid cleaning device is determined by the configuration of each coke oven (furnace lid or small lid). .

  Further, in the small lid cleaning device 47 according to the above embodiment, the case where the nozzle portion 473a of the water cleaning means 473 and the blade portion 474a of the blade cleaning means 474 are connected has been described. For example, the nozzle part of the water cleaning means and the blade part of the blade cleaning means may be configured to be individually movable.

  Further, in the small lid cleaning device 47 according to the above embodiment, the case where the blade part 474a of the blade cleaning unit 474 rotates is described, but the present invention is not limited to this case. For example, the blade cleaning means may be a case where the blade portion is formed of a scraper. That is, the blade cleaning means may adopt a configuration in which the attached tar and carbon are scraped off by the blade portion.

  In addition, in the small lid cleaning device 47 according to the above-described embodiment, the case where the blade cleaning unit 474 is provided has been described, but the present invention is not limited thereto. That is, the blade cleaning means 474 is not an essential configuration.

  Further, in the small lid cleaning device 47 according to the above-described embodiment, the case where the distance detection unit 475d is the measurement method using the laser has been described, but the case is not limited thereto. For example, the distance detection unit may detect the image data acquired by the imaging unit 475b.

  Specifically, the distance detection unit may measure the separation distance between the imaging unit 475b and the small lid 122 from the region of the small lid 122 (the size of the small lid 122) in the acquired image. In the case of adopting such a configuration, for example, the origin detection unit 475c detects a region having a high correlation value with the pattern image data E (see FIG. 11B) or an image of the small lid from the entire image data D. When detecting data (see FIG. 11C), the pattern image data E and the entire image data D may be expanded or contracted (large or small).

  Further, in the small lid cleaning device 47 according to the above-described embodiment, the case where the moving unit 476 includes the industrial robot 476a having four degrees of freedom has been described, but the invention is not limited thereto. For example, the moving means may be provided with an industrial robot having five or more degrees of freedom.

  Further, the moving means may be composed of equipment such as a cylinder, a gear, and a motor. Specifically, the moving means is configured by three cylinder mechanisms with three degrees of freedom for moving in the vertical direction, the horizontal direction, and the front-back direction, and switching between the water cleaning means 473 and the blade cleaning means 474. One degree of freedom may be configured by a rotation (motor shaft) mechanism that receives the drive of the motor.
