Description

The present invention relates to a coke oven fixed refractory stacking system, and more particularly to a coke oven fixed refractory stacking system that can automatically stack various types of fixed refractories automatically and accurately.
The present invention also relates to a coke oven fixed refractory stacking method performed using the coke oven fixed refractory stacking system.

  Metallurgical coke used for iron making is produced by dry distillation of coal in a chamber furnace type coke oven. A chamber-type coke oven is configured by alternately arranging a carbonization chamber and a combustion chamber that supplies heat to the carbonization chamber in the furnace width direction, such as a refractory brick that separates the carbonization chamber and the combustion chamber. Heat is supplied from the combustion chamber to the carbonization chamber via a fixed refractory. Some furnace-type coke ovens have more than 100 furnace chambers, and can be said to be huge brick structures with a total length of 100 m or more and a height of 10 m or more.

  The construction of a coke oven is currently carried out manually by a builder. In a manually built furnace, it is necessary to repeat the process of applying mortar to each fixed refractory such as bricks with a trowel and stacking them. Furthermore, the standard refractories used in the coke oven weigh 10 and a tens of kilograms, and the work of stacking them is extremely hard work. For this reason, there is a need to mechanize and automate the stacking work of standard refractories to reduce labor.

On the other hand, in the field of architecture, as described in Patent Document 1, a system for automatically stacking bricks has been proposed. In the system described in Patent Document 1, bricks are transported by a conveyor, and bricks are stacked using a brick stacking robot provided with an adhesive application head.

Special table 2009-521630

  However, since the system described in Patent Document 1 was developed for brick building in general building construction, it is used for stacking regular refractories in building a furnace coke oven. It is not possible. The reason is as follows.

  A typical building is constructed by stacking bricks of the same shape (usually a rectangular parallelepiped) and the same dimensions. On the other hand, coke ovens are constructed by complex combinations of fixed refractories having various shapes such as rectangular, trapezoidal, and L-shaped when viewed from above. In the system for a general building as described in the cited document 1, it is difficult to handle the fixed refractories of various shapes in this way, and each fixed refractory is changed to its shape. It cannot be stacked in the appropriate position.

  In addition, a coke oven is required to have a very high dimensional accuracy as compared with a general building. Therefore, the tolerance of the standard refractories to be stacked at the time of building the coke oven is strictly determined in units of several millimeters, and it is necessary to accurately stack the standard refractories to satisfy this. However, since the regular refractory actually used has a variation in dimensions of about several millimeters, the required accuracy cannot be satisfied even if these are simply stacked. In the case of manual loading, after taking into account such variations in the size of the standard refractory, the standard refractory was piled up while making adjustments to obtain the final dimensional accuracy of the coke oven. The system as described in 1 cannot make such subtle adjustments.

  The present invention has been made in view of the above circumstances, and in the construction of a coke oven used in a state where various types of regular refractories are mixed, these regular refractories can be accurately obtained regardless of manpower. An object is to provide a coke oven fixed refractory stacking system and a coke oven fixed refractory stacking method that can be stacked.

  Next, a method for carrying out the present invention will be specifically described. The following description shows a preferred embodiment of the present invention, and the present invention is not limited to the following description.

  The coke oven fixed refractory stacking system of the present invention has at least one fixed refractory stacking section and at least one fixed refractory supply section for supplying the fixed refractory to the fixed refractory stacking section. ing.

<< Standard refractory stacking section >>
First, the fixed refractory stacking part in the coke oven fixed refractory stacking system of the present invention will be described. The regular refractory stacking unit is for stacking regular refractories to directly construct a coke oven or to make a block used for construction of a coke oven. The standard refractory stacking unit has at least a shape, a dimension, and a position of a standard refractory disposed on the conveyor, and a conveyor that conveys a standard refractory supplied from a standard refractory supply unit described later. A measuring means for measuring; a fixed refractory stacking robot for stacking the fixed refractory; a control means for controlling the fixed refractory stacking robot based on a result measured by the measuring means; and the fixed refractory Mortar application means for applying mortar.

  FIG. 1 is a schematic view of a fixed refractory stacking portion 10 according to an embodiment of the present invention as viewed from the side. The standard refractory stacking unit 10 includes a conveyor 20 that conveys the standard refractory 11, a measuring unit 30 that measures the shape, dimensions, and position of the standard refractory 11, and a standard refractory stacking robot 40 that stacks the standard refractory 11. I have. The shape, dimensions, and position of the standard refractory are hereinafter referred to as the shape of the standard refractory.

  The fixed refractory stacking robot 40 lifts and moves the fixed refractory 11 transported by the conveyor 20, and loads the fixed refractory 11 on the stacking base 12. The operation of the fixed refractory stacking robot 30 at that time is controlled by the control means 50 based on the shape of the fixed refractory measured by the measuring means 30. The mortar 13 is applied to the surface of the stacked regular refractory by the mortar application means 60, and the regular refractory is stacked thereon by the regular refractory stacking robot 30. Next, the configuration and operation of each part of the standard refractory stacking part 10 will be described in detail.

<Standard refractories>
The fixed refractory is not particularly limited, and any fixed refractory such as brick or precast block can be used. Especially, it is preferable to use the normal fixed refractory material used when constructing a coke oven by hand.

<Loading location>
Any place can be used as a loading place. For example, the coke oven can be directly constructed using the location where the coke oven is constructed as a loading place. In addition, it is possible to manufacture a block used for building a coke oven by stacking standard refractories at a place other than the construction place of the coke oven. In that case, after forming a block of a predetermined size by stacking fixed refractories, the obtained block can be transported to a coke oven construction site, and the block can be stacked to construct a coke oven.

  In the embodiment shown in FIG. 1, a movable gantry 12 is used as the stacking place, and a standard refractory is stacked on the gantry 12 to produce a block. The platform 12 is installed on a rail 13 and can travel on the rail 13. Prior to the stacking of the standard refractory, the loading platform 12 is moved and fixed to a position where the standard refractory is stacked. An overhead crane, a heavy machine, etc. can be used for installation of the platform 12 on the rail 13.

<Conveyor>
The fixed refractory 11 used for the building is transported by the conveyor 20 to the side of the fixed refractory stacking robot 30. Any conveyor such as a belt conveyor can be used as the conveyor.

  However, some fixed refractories used in coke ovens have irregularities called dowels on the upper and lower surfaces of the fixed refractory. This dowel consists of a convex part provided on the lower surface of the standard refractory and a concave part provided on the upper surface of the standard refractory, and when the standard refractory is stacked, the convex part and concave part mesh with each other, Has the effect of firmly fixing the refractories together. However, when a regular refractory having such a dowel is used, it is difficult to stably convey the regular refractory with a normal conveyor because of the convex portion on the lower surface thereof. Therefore, it is preferable to use a conveyor having a fixed refractory support portion 21 on the transport surface that supports the fixed refractory while avoiding the convex portion on the bottom of the fixed refractory. The shape of the fixed refractory support portion is not particularly limited as long as it can support the fixed refractory while avoiding the convex portion on the bottom surface. As an example, there is a fixed refractory support portion including two support bases 22 as shown in FIG. The support base 22 is provided on the transport surface of the conveyor 20 so as to extend in the transport direction, and the fixed refractory 11 is transported while being placed on the support base 22. By making the height of the support base 22 larger than the convex portion on the bottom surface of the fixed refractory 11, the fixed refractory can be stably conveyed. In the coke oven fixed refractory stacking system of the present invention, it is preferable to provide a support base having the above-described shape on all the conveyors for transferring the fixed refractory.

<Measuring means>
The standard refractory 11 conveyed by the conveyor 20 is then stacked at a predetermined position by the standard refractory stacking robot 40. In the present invention, the standard refractory stack 11 by the measuring means 30 is stacked prior to stacking by the standard refractory stacking robot 40. It is important to measure the shape of the refractory. As described above, fixed refractories having various shapes such as a rectangle, a trapezoid, and an L shape are used for the coke oven as viewed from above. Therefore, by measuring the shape and dimensions of the fixed refractory in advance and controlling the fixed refractory stacking robot 40 based on the information, it is possible to automatically stack the fixed refractory at an appropriate position according to the shape. It becomes. In addition, although there is some variation in the dimensions of the standard refractory, it is possible to correct the position where the standard refractory is stacked based on the measured information on the dimensions of the standard refractory.

  The apparatus used for measuring the shape and the like of the fixed refractory is not particularly limited, and any apparatus can be used as long as it can measure at least the shape, size, and position of the fixed refractory. The measurement may be performed with a single device, or a combination of a plurality of devices of the same type or different types may be used.

  In the embodiment shown in FIG. 1, the measuring means 30 includes an image sensor 31 and a distance sensor 32 installed above the conveyor. As the image sensor 31, any image sensor such as a CCD camera can be used. The image sensor 31 acquires image data of the fixed refractory 11 on the conveyor, and processes the image data to detect the shape, size, position, and the like viewed from the upper surface of the fixed refractory 11. The upper surface shape of the fixed refractory 11 may be detected as a contour by processing image data. Information on the position of the fixed refractory can be obtained by analyzing image data based on information on the position where the image sensor 31 is installed, for example. Further, the inclination of the standard refractory can be measured based on the image data obtained by the image sensor 31, and the obtained inclination information can be used for controlling a robot or the like to be described later. For example, when the image sensor 31 is installed above the conveyor as shown in FIG. 1, the inclination (inclination in the horizontal plane) of the fixed refractory 11 seen from above is detected from the obtained image. be able to.

  As the distance sensor 32, any distance sensor including a laser displacement meter can be used. As shown in FIG. 1, the distance to the upper surface of the fixed refractory 11 is measured using the distance sensor 32 installed above the conveyor. The height of the fixed refractory 11 can be obtained by taking the difference between the measured distance and the distance to the conveying surface of the conveyor or the upper surface of the support base 22. In addition, the inclination of the fixed refractory 11 with respect to the horizontal plane can be calculated from the measurement result obtained by the distance sensor 32. The calculation of the inclination may be performed using measurement results of a plurality of distance sensors, or may be performed using results of measurement at a plurality of points by moving a single distance sensor. In the embodiment shown in FIG. 1, the measuring means 30 is installed above the conveyor so as to face the upper surface of the standard refractory 11. It can also be installed at other positions, such as diagonally above. A plurality of measuring means installed at different positions can be used in combination.

  Information relating to the shape and the like of the fixed refractory obtained by the measuring means as described above is sent to the control means 50 and used for controlling the fixed refractory loading robot 40. For example, the control means 50 can determine the optimum grip pattern by the sandwiching portion of the fixed refractory stacking robot 40 described later based on the information obtained by the measurement means 30. It is also possible to calculate the barycentric point and inclination angle of the fixed refractory based on the information obtained by the image sensor 31 and the distance sensor 32, and to perform control by the control means 50 based on them.

  The measurement by the measuring means may be performed at any timing as long as the fixed refractory is transferred by the fixed refractory loading robot, but as shown in FIG. 1, the fixed refractory 11 is placed on the conveyor. From the viewpoint of efficiency, it is preferable to carry out the reaction when there is. In that case, the conveyor is stopped when the standard refractory arrives at the measurement position, and the measurement is performed with the standard refractory stopped.After the measurement is completed, the standard refractory is placed on the conveyor by the standard refractory loading robot. It is preferable to resume the conveyance by the conveyor after removing from the conveyor. In addition, when using only a standard refractory that does not have a convex part on the lower surface, or when the presence of the convex part does not interfere, the standard refractory is transferred from the conveyor to a table connected to the end of the conveyor. Measurements can also be made after

  In this embodiment, the measurement is performed using the measuring means 30 installed above the conveyor 20, but an image sensor and a distance sensor are mounted on the arm of the standard refractory stacking robot 40 and measured. It can also be used as a means. When using the measuring means mounted on the arm of the fixed refractory loading robot 40, the measurement may be performed at one point, or the arm may be moved and the measurement may be performed at a plurality of points. Further, the measuring means 30 installed above the conveyor 20 and the measuring means mounted on the arm of the robot 40 can be used in combination.

<Standard refractory loading robot>
After the measurement by the measuring means, the fixed refractory 11 is transferred by the fixed refractory loading robot 40 and stacked at an appropriate position on the platform 12. The type of the robot used as the standard refractory stacking robot is not particularly limited, and any robot can be used as long as it has a load capacity, a movable range, and accuracy required for the standard refractory stacking of the coke oven. As the fixed refractory loading robot, an arm type robot which is a kind of industrial robot is preferably used, and a vertical articulated robot is more preferably used. In the embodiment shown in FIG. 1, a vertical articulated robot is used as the standard refractory loading robot 40. The fixed refractory stacking robot 40 is installed on a rail 49 laid in parallel with the rail 13, and is movable in parallel with the longitudinal direction of the conveyor 20 and the longitudinal direction of the loading platform 12.

  A holding portion for holding the fixed refractory 11 is provided at the tip of the arm of the fixed refractory stacking robot 40. The mechanism of the holding part is not particularly limited, and any mechanism can be used as long as it can appropriately hold and release the fixed refractory. Examples thereof include a parallel square flat hand, a fulcrum square flat hand, and a vacuum suction type hand.

  In the embodiment shown in FIG. 1, a holding part 41 that holds the fixed refractory with a plurality of holding members is provided as a holding part. The structure of the clamping part 42 is shown in FIG. The clamping unit 41 used here is an improved version of a holding mechanism called a parallel square flat hand (parallel hand) in accordance with the object of the present invention. In the figure, reference numerals 42a and 42b denote clamping members for sandwiching and holding the standard refractory. Although the shape of the holding member is not particularly limited, it is preferable that the surface in contact with the fixed refractory is flat as shown in FIG. 3 because the contact area increases, and as a result, the fixed refractory can be stably held. Moreover, it is preferable to provide the anti-slip | skid members 43a and 43b for improving holding force in the part which contacts the fixed refractory material of the clamping members 42a and 42b. As the non-slip member, for example, a thermosetting elastomer such as general rubber, a thermoplastic elastomer such as silicone rubber, and other resins can be used. In the embodiment shown in FIG. 3, plate-like rubber is provided as anti-slip members 43a and 43b on the surfaces of the holding members 42a and 42b that come into contact with the fixed refractory. Further, by providing an anti-slip member made of an elastic material such as rubber, it is possible to prevent the fixed refractory from being damaged.

  The clamping members 42a and 42b are configured to hold or open the standard refractory by opening and closing. Here, in the present embodiment, the two clamping members open and close by linearly moving in a direction toward each other or a direction away from each other. The opening and closing of the holding member may be performed by moving the two holding members together or by moving only one of them. In the example of the clamping unit shown in FIG. 3, the clamping member 43 a can be opened and closed by moving the clamping member 43 a in the direction of arrow A using the air cylinder 44.

  Furthermore, it is preferable that at least one of the holding members has a variable angle of the contact surface that contacts the fixed refractory of the holding member. Thereby, even when the side face of the fixed refractory is inclined (not parallel to the opposite side face), the holding member rotates in accordance with the inclination of the side face of the fixed refractory, thereby stably Can hold regular refractories. The method of rotating the clamping member is not particularly limited, and the clamping member is provided so as to be freely rotatable within a certain angle range, and when the fixed refractory is clamped, the side surface of the fixed refractory is inclined. It can also be rotated so as to follow. Further, the holding plate can be rotated at an arbitrary angle using a driving device such as a motor.

  In the example of the clamping unit shown in FIG. 3, the clamping member 42 a is fixed to the rotating shaft 46 connected to the servo motor 45 and can rotate in the direction indicated by the arrow B. The servo motor 45 is driven by a signal from a control means described later, and adjusts the angle of the holding member 42a in accordance with the shape of the standard refractory. In the above example, one clamping member can be opened and closed and rotated. However, one clamping member can be opened and closed, and the other clamping member can be rotated. Further, both the clamping members may be openable and closable and rotatable.

  Furthermore, it is preferable that at least one of the clamping members can change the position of the clamping member in a direction parallel to a contact surface that contacts the fixed refractory. Thereby, even if the shape seen from the upper surface is a fixed refractory having a special shape such as an L shape, the sandwiching member can be moved in parallel to a position corresponding to the shape, and the fixed refractory can be stably held. The translation method is not particularly limited, and any driving device can be used. In the example of the clamping unit shown in FIG. 3, a ball screw 47 and a motor 48 for moving the clamping member 42b in the direction of arrow C are provided. As the motor, a stepping motor or a servo motor can be used, and the motor is driven by a signal from a control means described later.

<Control means>
The operations of the fixed refractory loading robot 40 and its holding part (clamping part) are controlled by the control means 50. In this embodiment, after measuring the shape of the fixed refractory 11 conveyed by the conveyor 20 with the measuring means 30, the fixed refractory 11 is sandwiched by the sandwiching portion 41 of the regular refractory stacking robot 40. At that time, the angle and position of the holding members 42a and 42b are adjusted by the control means 50 in accordance with the shape of the fixed refractory 11 or the like. Then, the arm of the fixed refractory stacking robot 40 is driven based on the position of the fixed refractory measured by the measuring means 30, and the fixed refractory is held by the holding portion 41.

  The sandwiched fixed refractory is lifted and moved by the fixed refractory stacking robot 40 and stacked on a predetermined position of the loading platform 12. At this time, the position where the standard refractory is loaded is determined by the control means based on the shape of the standard refractory measured by the measurement means 30. It is preferable to store in advance in the storage device connected to the control means 30 or the control means the information on which shape the fixed refractory is placed in which position. Further, the position where the standard refractory is actually loaded is corrected based on the shape and size of each standard refractory measured by the measuring means 30. Thereby, a fixed form refractory can be piled up accurately, without being influenced by the error of the shape and dimension of a fixed form refractory.

<Mortar application means>
A mortar 13 for joining the fixed refractory 11 is applied by a mortar applying means 60 at a position where the fixed refractory 11 is stacked. In the embodiment shown in FIG. 1, the mortar application means 60 includes a pump 61 for transferring the mortar 13, a pipe 62 connected to the pump 61, and a nozzle 63 connected to the pipe 62 for applying the mortar in a strip shape. And a coating robot 64 to which a nozzle 63 is attached. The nozzle 63 is connected to the pipe 62 via the dispenser 65, and a rotating means (not shown) for rotating the nozzle 63 about the central axis of the dispenser 65 is provided at a connection portion between the nozzle 63 and the dispenser 65. The nozzle 63 can be rotated in accordance with the direction of the surface on which the mortar is applied. The shape of the nozzle 63 is not particularly limited, and any nozzle can be used. From the viewpoint of performing coating over a wide area with a uniform thickness, it is preferable to use a flat nozzle.

  As the coating robot 64, it is preferable to use an arm type robot that is a kind of industrial robot, and more preferably a vertical articulated type robot, like the standard refractory loading robot 40. The application robot 64 is installed on a rail 66 laid in parallel to the rail 14, and can move in parallel with the longitudinal direction of the stacking table 12.

  The procedure for applying the mortar and the operation of the mortar application means at that time are not particularly limited, as long as it is an aspect that can apply the necessary amount of mortar at the position necessary to join the stacked refractories together, Any method can be employed. As an example, each time one fixed refractory is loaded by the fixed refractory stacking robot 40, the mortar can be applied to the position where the fixed refractory is loaded. The position where the standard refractory is loaded is a position including at least the portion where the lower surface of the fixed refractory to be contacted, that is, the upper surface of the fixed refractory already stacked in the lower stage. If a fixed refractory is already loaded at the position where the side of the fixed refractory to be loaded touches, the side of the fixed refractory that is in contact with the fixed refractory to be stacked is also mortar. Is preferably applied. Therefore, the nozzle 63 of the application robot 64 can apply the mortar in an arbitrary direction such as a lateral direction as well as a downward direction by moving the joint of the application robot 64 and / or rotating the nozzle 63. It is preferable to be configured to be able to. In addition to the sequential application of mortar for each location corresponding to one standard refractory as described above, two or more, or in some cases, one stage, etc. You may apply mortar. In addition, when loading the first-stage fixed refractory on the stacking base 12, it is not necessary to apply mortar in advance.

  Although the mortar application unit 60 can be controlled by a separately provided control unit, it is preferably performed by a control unit 50 that controls the fixed refractory loading robot 40 as shown in FIG. Thereby, operation | movement of the fixed refractory stacking robot 40 and the mortar application means 60 can be interlocked, and fixed refractory stacking can be performed efficiently. The position where the mortar is applied can be stored in the control means in advance, or can be determined by the control means based on information on the fixed refractory already loaded. Even when the mortar is applied to a predetermined position, it is preferable to correct the application position based on information on the shape of the fixed refractory already stacked.

  By repeating the above procedure, the standard refractories are stacked. When a block for use in building a coke oven is produced at a location different from the construction site of the coke oven, the completed block is transported to another location. The method for transporting the blocks is not particularly limited, and any method can be used. However, as shown in the embodiment shown in FIG. 1, a standard refractory material is stacked on the platform 12 installed on the rail 14. In this case, it is preferable to carry out the platform 12 by running on the rails 14. The unloaded block can be transported directly to the coke oven construction site, or after being transported to a temporary storage location, and then transported from the storage location to the coke oven construction site according to the progress of the coke oven construction. You can also. And in the fixed refractory stacking part 10 after a block is carried out, the empty mounting base 12 in which a fixed refractory is not loaded can be installed again, and a new block can be produced.

  In addition, when using the coke oven fixed refractory stacking system of the present invention to perform the regular refractory stacking work at the coke oven construction site instead of making blocks, the fixed refractory stacking is performed at one place. Once done, the coke oven standard refractory stacking system can be moved in whole or in part as needed to stack the standard refractories at different locations. By repeating this, a coke oven is built.

  The regular refractory stacking unit 10 shown in FIG. 1 includes a conveyor 10, a measuring unit 20, a fixed refractory stacking robot 40, a control unit 50, and a mortar coating unit 60 one by one. Can be independently 2 or more.

<< Standard refractory supply section >>
Next, the fixed refractory in the coke oven fixed refractory stacking system of the present invention will be described. The fixed refractory supply unit is for supplying the fixed refractory to the above-described fixed refractory stacking unit. The fixed refractory storage means and the fixed refractory stored in the fixed refractory storage means are fixedly formed. And a transfer means for transferring onto the conveyor of the refractory stacking section.

  A large amount of regular refractories of various shapes are used for building a coke oven. Therefore, the fixed refractory to be used is temporarily stored in the fixed refractory storage means, and from the fixed refractory storage means, the required type of fixed refractory is transferred to the fixed refractory using the transfer means. By passing to the conveyor of a refractory stacking part, supply of a regular refractory can be automated and a regular refractory can be piled up efficiently.

  The form of the fixed refractory storage means is not particularly limited and can be any form. For example, it is possible to arrange regular refractories directly on the floor surface and lift and transport the necessary regular refractories by a transfer device described later. It is preferable to store a regular refractory in the. More preferably, the fixed refractory storage means includes a sending means for sending the fixed refractory to the transfer means.

  And the said transfer means is for delivering the fixed refractory acquired from the said fixed refractory storage means to the conveyor of the said fixed refractory stacking part, if a fixed refractory can be transferred The form is not limited and can be arbitrary. For example, when the fixed refractory storage means and the conveyor are close to each other, an arm type robot such as a horizontal articulated robot or a vertical articulated robot can be used as the transfer means. Moreover, the transfer conveyor provided between the said fixed refractory storage means and the said conveyor can be used as said transfer means. In addition, it is preferable that the said transfer means is self-propelled, for example, it is more preferable to provide the conveyor for transfer on the cart which can be self-propelled. If the transfer means can be self-propelled, the fixed refractory can be obtained from various positions even when the fixed refractory storage means is large. Further, even when a plurality of fixed refractory stacking sections are provided for one fixed refractory supply section, if the transfer means can be self-propelled, the plurality of transfer means can be formed by one transfer means. The regular refractory can be supplied to the regular refractory stacking section.

  FIG. 4 is a schematic view of a coke oven fixed refractory stacking system according to an embodiment of the present invention, and a block used for building a coke oven is manufactured using the coke oven fixed refractory stacking system. Shows the case. Moreover, FIG. 5 is the schematic which looked at the coke oven fixed-type refractory stacking system in the same embodiment from the side. Hereinafter, with reference to FIG. 4 and 5, the structure and operation | movement of the said fixed refractory supply part in this embodiment are demonstrated.

  The coke oven fixed refractory stacking system 1 in this embodiment includes a fixed refractory stacking unit 10 and a fixed refractory supply unit 100. The standard refractory supply unit 100 includes a storage shelf 110 as a standard refractory storage unit and a picking device 120 as a transfer unit.

<Standard refractory storage means>
The storage shelves 110 as the standard refractory storage means store various shapes of the regular refractories 11 used in the coke oven in a state of being classified by type. The storage shelf 110 is provided with a conveyor 111, and the fixed refractory 11 that has been input from the input port 112 is conveyed toward the discharge port 113 by the conveyor 111. On the outlet side of the storage shelf 110, a delivery conveyor 114 is provided for sending out the stored standard refractories 11 to the transfer means one by one. A stopper 115 that can be raised and lowered is provided at the outlet 113. Is provided. As in the case of the conveyor 20 shown in FIG. 2, a fixed refractory support portion (illustrated) for supporting the fixed refractory while avoiding the convex portion on the bottom of the fixed refractory is formed on the transfer surfaces of the conveyor 111 and the delivery conveyor 114. Is not provided).

<Transfer means>
The picking device 120 as the transfer means has a movable carriage 121 and a picking conveyor 122 installed on the movable carriage 121 for conveying an irregular refractory, and further movable. The carriage 121 is installed on the rail 123. A fixed refractory support portion (not shown) for supporting the fixed refractory material while avoiding the convex portion on the bottom surface of the fixed refractory material is provided on the conveying surface of the picking conveyor 122, similarly to the conveyor 20 shown in FIG. Is provided.

  As shown in FIGS. 4 and 5, the conveyor 20, the conveyor 111, the delivery conveyor 114, and the picking conveyor 122 are preferably installed in parallel to the longitudinal direction of the stacking table 12. In addition, the rail 123 is preferably laid in a direction perpendicular to the conveying direction of the conveyor 20 and the conveyor 111. By laying the rails 123 in this way, even when the storage rack 110 has a large number of conveyors 111 and discharge ports 113 corresponding to the conveyors 111, the picking device 120 is moved on the rails 123. A standard refractory can be transferred with one picking device. Similarly, even if a plurality of standard refractory stacking portions 10 are provided, by moving the picking device 120 on the rail 123, a single picking device can transfer the fixed refractory stacking portions to a plurality of standard refractory stacking portions. Refractories can be transferred. Note that the number of picking devices (transfer devices) may be one, or two or more.

<Control means>
The fixed refractory supply unit 100 includes control means (not shown). The control means includes a storage shelf 110 as a standard refractory storage means and a picking device 120 as a transfer means so as to supply an appropriate type of standard refractory to the standard refractory stacking unit 10 at an appropriate timing. Control the behavior. The control means may also serve as the control means 50 of the standard refractory stacking unit 10.

Next, an example of operation | movement of the fixed refractory supply part 100 in this embodiment is demonstrated.
The fixed refractory 11 stored in the storage shelf 110 is conveyed toward the discharge port 113 by the conveyor 111 and reaches the delivery conveyor 114. Next, the stopper 115 is raised to open the discharge port 113, the delivery conveyor 114 is driven, and the fixed refractory 11 is sent out. At this time, the picking device 120 is moved in advance to a position where the standard refractory 11 is stored. Then, simultaneously with the delivery conveyor 114, the picking conveyor 122 of the picking device 120 is operated to move the fixed refractory 11 from the delivery conveyor 114 onto the picking conveyor 122.

  After one fixed-type refractory 11 is sent out, the stopper 115 is lowered to prevent the subsequent fixed-type refractory from being discharged from the discharge port 113. At this time, a photoelectric sensor may be provided immediately before the stopper 115, and the operation of the delivery conveyor 114 may be stopped when the standard refractory is detected by the photoelectric sensor. The picking device 120 that has received the fixed refractory 11 then moves to the front of the conveyor 20, operates the picking conveyor 122 again, and transfers the fixed refractory onto the conveyor 20.

  The fixed refractory 11 transferred onto the conveyor 20 is stacked on the loading platform 12 by the fixed refractory stacking robot 40 as described in the description of the fixed refractory stacking unit 10. In the present embodiment, the fixed refractory stacking robot 40 and the coating robot 64 are respectively installed on the rail 49 and the rail 66, and the rail 49 and the rail 66 are laid in parallel to the longitudinal direction of the stacking base 12. Therefore, a long block can be easily manufactured by moving these robots on the rail.
