Description

DETAILED DESCRIPTION OF THE INVENTION This issue #J relates to a nozzle automatic connection/separation device that automatically connects or disconnects the nozzle to the nozzle receiver provided on the bottom surface 4I of the container.

As shown in FIGS. 1 and 2, a conventional device of this type includes a nozzle receiver 6 installed on the bottom 5 of the container I, and a device with a nozzle attached to a stand z2 near the container 1. There is a fi-position where the nozzle 10 is manually connected or separated by the 11.The nozzle attachment device 11 used for this conventional g-position is as follows:
Frame 12 [rotatable vertically (rod support 3 on support 18)
o Supported by rotating bin I4, - #1iir support 1g [
The other end of the vertically movable cylinder I5, which is connected with a pin, and the lower end of the rod receiver 30 are connected with a pin, and the rod receiver 8°? The rod receiver 30C has a nozzle support 19 fixed to its tip, and the nine rods 17? roller 8
1, and the nozzle support ring 9 can be moved freely by operating the handles 82f of the same number front and rear.

According to this conventional device, first, two nozzle support rods 2 are fixed to the nozzle support 19 on opposite peripheral sides C of the nozzle IO.
After the nozzle 10 is swingably placed on the nozzle support 19 by placing the IQ, the operator operates the coupler 32 to move the nozzle 10 (7) to a position where the upper end N opening faces the lower surface of the nozzle receiver 6. 10, and then actuate the vertical cylinder 15 according to an operation command not shown in the drawings to move the nozzle support 19 upward, thereby connecting the entire upper end opening of the nozzle IO to the nozzle receiver 6, and vice versa. By this operation, the nozzle receiver 6 and the nozzle IO are separated.

However, according to such a conventional device, the operation of placing the nozzle on the nozzle support 19 and moving it directly below the nozzle receiver 6 of the next nozzle 10i container l is performed by the operator by operating the handle 32 by visual estimation. Due to an error in visual measurement, the positions of the nozzle receiver 6 and the nozzle 1O may be misaligned and the connection cannot be made, resulting in the disadvantage that the alignment operation must be performed again, which is time-consuming.

This invention has been made in view of the above circumstances, and aims to provide a complete nozzle automatic connection/separation device that can reliably and automatically connect or separate a nozzle receiver and a nozzle in a single operation, and has its characteristics. A tentacle is installed at the tip of the rod that is operated by a cylinder for forward and backward movement provided in place of the rod holder, and is guided by the tentacle guide to form a nozzle around the nozzle holder. When the nozzle support is moved upward by the horizontal guide mechanism that guides the nozzle guide downwards and the vertical movement cylinder, the nozzle is guided by the nozzle guide frame (the upper guide mechanism that guides it and connects it to the nozzle receiver). be.

Embodiments of the present invention will all be described below based on the description of the drawings.

In Figures 3 to 6, % lr! For example, it is a container such as a ladle used in a steelworks, and after fully filling the inside with molten steel, it is rotated and transferred above the tundish 2 by a swirling tower device (not shown in Figure 1) and stopped within a predetermined error range. . The discharge hole 3 formed at the bottom of the container 1 is contacted by a valve rod 4 that moves up and down by a device not shown to prevent the discharge of molten steel. The nozzle guide frame 8 has a nozzle receiver 6 projecting thereon and a table surface 7 around the nozzle receiver 6 that has an umbrella-shaped opening inside.
is formed. Historically, on the bottom surface 5 of the container 1, there was a tentacle guide 9 made of a board bent in the shape of a square. It is fixed facing outward. In the vicinity of the container 1 in the direction connecting the center of the bottom surface 5 of the container 1 and the tip of the tentacle kite 9, a nozzle attachment device 11 for connecting or separating the nozzles 10 to the nozzle receivers 6 of the entire container 1 is fixed to the ground or a fixed object. It is attached to a pedestal 12. The nozzle mounting device 11tri is rotatably provided perpendicularly to the pedestal 12 and has a companion support 13. A cylinder 16 for longitudinal movement is supported by a pivot pin 14 on the support body 13. A vertically moving cylinder 15 whose one end is pin-coupled to the lower part of the support 13 and the other end is pin-coupled to the lower tip of the longitudinally movable cylinder 16. Forward and backward motion cylinder 1
A U-shaped nozzle support 1940 is provided at the tip of the rod 17 of No. 6 so as to be rotatable horizontally via a connecting pin 18.
The upper C of the rod 17 is composed of tentacles 20 that protrude upward. Furthermore, from the center position inside the nozzle support 19, the tentacle 2
The distance to the protruding position 0 is set approximately equal to the distance from the center of the nozzle receiver 6 to the tip of the tentacle guide 9. Nozzle 10 placed on the nozzle support 19
fi, nozzle support 1 while maintaining the vertical position while freely swinging.
9, there are two nozzle support rods 21i on opposite circumferential sides. Also, the nozzle support 19 is connected to the rod 17.
Both ends of the protrusion 22 are provided below the nozzle support I9 so as to be always centered on the extension line of the nozzle support I9. A centering spring 24 (fixed to the tip of the rod 17 and locked to the next frame 23)
Therefore, it is under pressure. A stop plate 25 fixed below the support body 13 is fixed to the pedestal 12 so that the cylinder 16 for longitudinal movement does not rotate in the horizontal direction beyond the stopping error range of the container 1, and hits two stoppers 26. In this way, the rotation of the longitudinal motion cylinder 16 in the horizontal direction is restricted.

The operation of the present invention having the above configuration will be explained. When the pressure fluid is supplied to the cylinder 16 for forward and backward movement in a state where the container l is rotatably transferred to the upper part of the tundish 2 and stopped in a concave circle with a predetermined error,
The rod 17 moves forward and the tentacle 20 comes into contact with the open side of the tentacle guide 9. Then, as the rod 17 moves further forward, the 20 tentacles slide along the tentacle guide 9, gradually advancing to the center of the tentacle guide 9, and finally reaching the tip and stopping.
At this time, the first longitudinal movement cylinder 16 rotates in the horizontal direction together with the support 13 and gradually displaces the posture, but the tentacle 20
reaches the tip of the tentacle guide 9 and stops and rotates at the same time? Stop and maintain a horizontal position. In this state 'J6
If the container l is stopped at the fixed position without any error,
The cylinder 16 for longitudinal movement and the rod 17 are located on a straight line connecting the center of the bottom surface 5 of the container 1, that is, the center of the nozzle receiver 6, and the tip of the tentacle guide 9, and the center of the nozzle receiver 6 and the tip of the tentacle guide 9 are located on a straight line. Since the distance between the tentacle 20 and the center of the nozzle 10 supported by the nozzle support (19) is almost equal, the upper end opening of the nozzle 10 is located almost directly below the nozzle receiver 6 of the container l. , when the container 1 is out of its normal position but stopped within a predetermined error [the curve], the line connecting the center of the tris nostle receiver 6 and the tip of the tentacle guide 9, and the cylinder 16 for forward and backward movement.
and the straight line passing through the center 7 of the rod 17 do not match, so the upper end opening of the nozzle 1O is not positioned directly below the nozzle receiver 6 of the container 1, but is located within the outer circumference of the nozzle guide frame 8. It's like &J. In either case C, when the tentacle 20 reaches the tip of the tentacle kite 9 and the forward movement of the rod 17 stops, the sensing device (not shown in Figure 1) is activated. Detected and commanded control 11 device C not shown? Give pressure fluid to the vertical movement cylinder 15? supply Then, the cylinder 16 for longitudinal movement rotates around the center of the rotating bin 14 and moves upward, so the nozzle support 19 at the tip of the rod I7 also rises, and the nozzle I supported by the nozzle support 19 via the nozzle support rod 21
The upper end opening of O is connected to the nozzle receiver 6, and this connected state is maintained until a separation command is given to the control device. When the container l is out of its normal position and stopped within a predetermined error range, the nozzle support 19 rises and the periphery of the tip opening of the nozzle IO is aligned with the surface 7E of the nozzle dormitory inner frame 8. When they come into contact and the nozzle support 19 rises, the nozzle IO is guided to the umbrella part 7, and the nozzle receiver 6 and the upper end opening of the nozzle IO are finally connected.

At this time, since the nozzle support λ19 is provided at the tip of the rod 17 so as to be able to rotate freely in the horizontal direction, even if the nozzle 10 is guided by the umbrella portion 7 of the nozzle guide frame 8 and moves toward the center of the nozzle receiver 6. The nozzle support 19 also moves accordingly.

In this way, after the nozzle receiver 6 and the nozzle 10 are connected, when the molten liquid 6JI4 in the container 1 is to be flowed down into the tank push 2, the valve stem 4 is raised by a device not shown in the drawing. Just open it. Then, the molten steel passes through the discharge hole 3 and the nozzle 10i and enters the tongue pusher 2.

Next, the nozzle receiver 6 and the nozzle IO? When separating, do you give a command to the control device? When the pressure fluid is discharged from the vertical motion cylinder 15 and the longitudinal motion cylinder I6, or when the supply direction is switched λ, the first longitudinal motion cylinder 16 is moved to the rotating bin 1.
4 (+- rotates downward as center, while rod I7
moves backward, so the nozzle ] 0 moves downward and then 1
Will it move in the direction of the forward/backward motion cylinder 16, move away from the nozzle receiver 6, and automatically stop, and the next container l of molten steel will be transferred (b) by the swirling tower device? stand by.

During this standby, the support 13 prevents the cylinder 16 for longitudinal movement from rotating more than necessary in the horizontal direction for some reason.
This is prevented by the stop plate 25 hitting a stopper 26 fixed to the pedestal 12.

As is clear from the above description, the nozzle automatic connection/separation device of the present invention uses the action of the horizontal guiding mechanism as the nozzle support 19 moves in the horizontal direction, that is, the nozzle support 19
A tentacle 2° protruding from a rod 17 that swingably supports the container 1 horizontally and vertically is guided by a tentacle guide 9 provided at the bottom of the container 1 with its pointed end 1, so that the tentacle 2° is placed on the nozzle support 19. Placed nozzle 1 o Nozzle receiver 6 of all containers
The nozzle guide frame 8 formed around the nozzle receiver 6 is moved horizontally downward, and further, due to the upward movement of the nozzle support +9, the nozzle guide frame 8 formed around the nozzle receiver 6 is moved toward the nozzle 1o.
Since the nozzle lo is connected to the nozzle receiver 6 by the action of guiding the upper end opening, this device does not require visual or manual force unlike conventional devices of this type. Since it is no longer necessary to align the nozzle receiver 6 and the nozzle 0, it is possible to reliably connect the nozzle 10 and the nozzle receiver 6 of the container holder in one operation, and to improve the efficiency of the connection and separation work between the nozzle 10 and the nozzle receiver 6 of the container cover. becomes possible.

Other embodiments of this invention shown in FIGS. 7 and 8? show. The difference from the previous embodiment is that one end of the cylinder 16 for longitudinal movement is attached to the frame 12 so that it can be forcibly rotated in the horizontal direction by a cylinder 27 for horizontal movement, and the tentacle guide 9 is attached to the bottom surface 5 of the container l. The difference is in the position and mounting direction. This embodiment differs from the previous embodiment in the operation when connecting the nozzle 10 and the nozzle receiver 6. After the container 1 has stopped, the tentacle 20i is rotated in the horizontal direction by the longitudinal movement cylinder 16 and the horizontal movement cylinder 27&S. 9, the other connection and separation operations and their effects are the same as in the previous embodiment.

FIG. 9 shows a centering device for the longitudinal movement cylinder 16 used in the embodiment shown in FIGS. 3 to 6. FIG.

That is, at the time of separation, both 1l of the stop plate 25 of the support body 13
Illwo mount 12 at one end? The centering lever 2s' is held by the supported centering lever 28, so that the entire cylinder 16 for longitudinal movement is centered at a predetermined position, and the centering lever 2s' is moved during the connection operation.
t (when opened, the cylinder 16 for longitudinal movement can freely rotate in the horizontal direction). Although this is done by the center cylinder 29, instead of this, the two centering levers 28 may be pulled or pressed in directions facing each other by an elastic body such as a spring.However, in this case (the connection Even during operation, the cylinder 16 for longitudinal motion receives a rotational moment in the direction of centering, so the pressure of the pressure fluid supplied to the cylinder 16 for longitudinal motion must be increased somewhat to increase the force by which the rod 17 extends. There may also be cases where the sliding resistance between the tentacle 20 and the tentacle guide 9 cannot be overcome.
