Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning device suitable for cleaning the back side of an obstacle.

The present invention is useful, for example, for cleaning the area around the push-up rod in a copper electrolytic fine brick anode continuous M casting machine. The device of the present invention is of course useful for other objects, but for convenience, the problems surrounding the push-up rod will be explained below as an example. Fig. 1 shows a generally well-known anode continuous casting device. An overview is shown. This anode continuous casting apparatus is equipped with a plurality of molds 2 along the circumferential direction on the upper surface of a one-rotation 'F4'' a plate 1, and as shown in FIG. A push-up rod 4 for demolding is inserted into each hole 3 so as to be able to protrude upwards, and the casting plate 1 is rotated once as shown by the arrow (6) in Fig. 1 to pour the metal at point 0. The magazine product (ano-y) that has been cooled and solidified during rotation is lifted up by a lifting machine 5 at point 0, and the following operations are performed continuously as the rotary casting plate rotates 10 times to produce anodes. .

In this case, the push-up rod 4 is in the third position from pouring to frying.
As shown in the figure, the hole 3a is closed, and at the stage of collection, the anode 6 is pushed up from the back side of the mold 2 as shown in FIG.

Then, the push-up a4 is lowered again when the anode 6 is relifted, and the push-up a4 is moved down again in order to perform the next pouring.
At this time, if a foreign object gets caught between the hole 3a and the push-up rod 4, it will not be possible to completely clear the hole 3a, Molten metal may enter there and prevent normal construction.

Therefore, it is necessary to clean the area around the hole opening 3a at the 0 point (see FIG. 1) just before the push-up rod 4 descends.

Conventionally, the reality is that cleaning work in this case relies entirely on the labor of the workers, who have to perform this monotonous work every now and then in poor environments, and therefore the work The problem was that the burden on staff was extremely heavy.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a labor-saving cleaning device that can automatically perform the above-mentioned cleaning work.

Hereinafter, the present invention will be specifically explained with reference to the drawings.

FIG. 5 shows the structure of an embodiment of the present invention. In FIG. 1, O is a rotating rod. This rotating rod 16 is the motor 11
It is driven to rotate as shown by the arrow (b). A support bracket 12 is provided perpendicularly to the rotating rod 10 at the tip of the rotating rod opposite to the rabbit connected to the motor 11. At both ends of the support bracket 12, that is, at positions symmetrical to the rotating rod 10, arms] 3 are rotated by pins 14 in the radial direction of the rotating rod 10 (in the direction of the arrow (-C)). It is mounted so that it can move freely. This arm 13 is supported by a pin above the center, and also at the end of the upper half above the pin 14 (on the rear end side)! 1
) 15 has been revised. Further, this arm 13 is biased by a spring (elastic member) 16 so that the upper half of the arm 13 having a weight 15 moves inward. On the other hand, the lower half of the arm 13 (below the pin 14, that is, the tip (1, 14 side)) is bent inward in a dogleg shape, and a brush 17 as a cleaning means is attached to the tip. This device is configured such that when the rotary rod 10ir1 rotates, the main p15 moves outward due to centrifugal force.

Next, a case in which the cleaning device having the above structure is used to completely clean the area around the push-up rod and the hole will be described with reference to FIGS. 6 to 8. In the figure, 2 is a mold, and 4 is a push-up rod. In this case, the push-up rod 4 has a tapered shape whose upper end widens upward as shown in the figure, and this becomes an obstacle when cleaning the hole opening 3a. Therefore, when cleaning the hole 3a, the apparatus p of the present invention is first supported by any supporting means and positioned directly above the push-up rod 4 as shown in FIG. Then, as shown in FIG. 7, the device p is gradually lowered by any means, and the brush 17 at the tip of the arm 13 is
It is positioned below the upper part of the push-up rod 4, which was an obstacle. At this time, since the lower half of the arm 13 is opened outward by the spring 16, it does not become an obstacle when passing the upper end of the push-up rod 4. Then, when the rotary rod 10 is rotated by the motor 11, as the rotational speed increases, the weight 15 moves outward and rotates the arm 13 in the direction of arrow (c), causing the lower half of the arm 13 to move inward. Move to. Then, while rotating, the brush 17 reaches the hole 3a, and the brush 17 reaches the hole 3a.
The surrounding area will be cleaned. After cleaning, motor 1
Stop the rotation of 1. Then, the force of the spring 16 causes the arm 13 to return to its original position, making it possible to raise the device p.

In this way, by simply moving the device itself up and down and rotating the motor 11, the area below the obstacle (the upper end of the push-up rod 4) can be cleaned without the need for manpower. can.

Next, as an application example incorporating the above-mentioned fEffip,
The push rod periphery automatic cleaning device M in an anode continuous casting device will be explained with reference to FIGS. 9 to 13. FIG. 9 is a plan view showing the overall configuration, FIG. 10 is a side view of the same,
1 to 13 are partially detailed views.

This device M is now installed at the 0 point of the anode continuous casting device shown in FIG. 1, and the rotary casting disk 1 is rotating in the direction of the arrow (A) in FIG.

In FIGS. 9 and 10, 20 in 1 figure is a pedestal,
This pedestal 20 is installed so as to be able to appropriately face above the mold 2 of the rotary casting machine 1 by extending from a cart 22 that can run on a rail 21 laid on the floor. An arcuate guide rail 23 is provided on the top surface of this pedestal 20.
Wheels 24 are fitted into the inner grooves 23a (see FIGS. 12 and 13) of the guide rail 23, and a movable base 25 is provided so as to be movable in the directions of arrows (E) and 1 (F). 7 In this case, the guide rail 23 has an arcuate curve with a predetermined curvature, and when the pedestal 20 is advanced to a predetermined position above the mold 2 of the rotary casting machine 1, the movable base 25 is positioned just above the mold 2 of the rotary casting machine 1. It is now possible to move in an arcuate trajectory centered on the rotation center of 1.

A movable table moving mechanism is provided as a means for removing the movable table 25, which is provided so as to be able to move in the same trajectory as the mold 2 above @Deaf 2.

The movable table moving mechanism has the following two functions:

■Move the movable table 25 from the initial position (the position shown in Fig. 9) in the direction of the arrow in synchronization with the rotation of the rotary casting plate 1; ■Move the movable table 25 in the direction of the arrow to return to the initial position. It performs two functions: resetting, and in this embodiment, it is divided into two mechanisms according to these two functions.

One is the i-structure, which is composed of a cylinder 26.26 attached to the movable table 25 and positioning rods 27, 27 attached to the end of the cylinder 26.26, in order to perform the function (2) above. , and the other is a mechanism constituted by a cylinder 28 peering through the projecting beam 20a of the pedestal 20 in order to perform the function (2) above.

First, to explain the former mechanism in detail, see Figure 11.
As shown in FIG. 2, the main body portion of the cylinder 26.26 is supported by a frame 29 hanging vertically on the movable table 25, and is attached facing downward. A positioning rod 27 guided by a guide part 30 is connected to the lot.
Further, a block 31 that is caught on the inner wall 2b of the mold 2 is attached to the bottom of the positioning rod 27. According to this mechanism, the block 31 is moved into the mold 2 on the rotating casting aluminum by extending the lot 0 of the cylinder 26, 26, as shown in the figure. Inner wall 2 on the rear side in the rotational direction of the moving mold 2
b, which causes the movable base 25 to return to its initial position (9th position).
(see figure) and move synchronously with the mold 2 in the direction of the arrow (e) in Fig. 9. That is, according to this mechanism, by operating the cylinders 26, 26 in a well-timed manner, the movable base 25 can be moved in exactly the same manner as the mold 2 using the rotational power of the rotary casting plate 1.

Next, regarding the latter mechanism, the main body of the cylinder 28 is peered into the protruding beam 20aK of the pedestal 20, and the rod tip is connected to the movable base 20, so that the former mechanism allows the movable body to be moved by a predetermined distance. The stand 25 can be returned to its initial position.

As mentioned above, by operating the cylinders 26 and 26, the position of the movable base 25 with respect to the mold 2 is determined, and the movable base 25 is caused to move in accordance with the mold 2, but as shown in FIG. A cylinder 32 is provided vertically downward on the movable base 25 at a position that corresponds to the push-up rod 4 in the mold 2 when it is in one position. In this case, the cylinder 32 is attached to another frame 33 vertically installed on the movable base 25, so that the rod can be extended and contracted up and down.

The above-mentioned cleaning device p of the present invention is attached to the maidservant in a downward direction.

The above-mentioned apparatus M is controlled in a predetermined sequence by, for example, providing a limit switch between it and the rotary casting machine 1 so as to be linked to the operation of the continuous casting apparatus.

Next, we will explain the actual operation of the device M having the above configuration. The mold 2 is automatically operated by the control device as follows by the control device. However, a limit switch installed between the casting board 1 and the cylinder 26.
26 is activated, the rod is lowered, and the positioning rod 27 lower block 31 enters the mold 2 which has reached a predetermined position below the pedestal 20. (2) This operation causes the inside of the mold 2 to be moved The side surface of the block 31 hits the wall 2b, and the movable base 25, which is the fixed cylinder 26 and t7, moves in synchronization with the movement of the mold 2.
is operated, lot 0 is lowered, and cleaning is performed by the cleaning device p as shown in FIGS. 6 to 8 described above.

(41) Then, when the cleaning is completed, the cylinder 32 is activated again by the timer to raise the rod.

(51 Then, when the lot ° of cylinder 32 increases (
), the cylinder 26.2 that was being positioned
6 operates, the positioning rod 27 at the lower end of the rod rises, and the block 31 moves away from the mold 2, releasing the synchronization of the one unit 25.

(6) Next, the cylinder 28 for return movement is operated to return the movable base 25 to the initial tr position, and the above-mentioned push-button process is completed, and the process of one cycle is completed, and the process waits until the next mold 2 arrives. According to the automatic cleaning device around the lifting rod, it is possible to automatically process all the conventional manual work while continuing the operation of the continuous casting device.

In the above example, the mechanism for moving the movable table was configured separately for the forward and return trips, but any mechanism that can cycle the movable table to move the mold may be used.
For example, by controlling the return movement cylinder 28 in this way, one cylinder 2B can move the reciprocating path! It is also possible to have the l1 function.

Further, in the above embodiment, a case is shown in which the brush 17 is provided as a cleaning means in the cleaning device fi2p, but in addition to this, a nozzle that blows out high-pressure air may be used as a cleaning means.

In the above embodiment, the support bracket 12 is made into a rod shape, and a pair of arms 13 are provided at both ends of the support bracket. , a configuration may be adopted in which a larger number of arms are attached.

As explained above, according to the present invention, cleaning around the push-up rod can be easily performed without manual effort, thereby saving the labor of five workers and promoting labor saving.
