していた。 To briefly explain the link bars 50, 50 and 51, 51 shown in FIG. , 54a and each link bar 5
0 and 51 are connected to an actuation plate 56 in the center via a link arm 55, and by rotating the actuation plate 56 in one direction in the horizontal direction, each of the link bars 50 and 51 is displaced inward. When cleaning the inner circumferential surface of the formwork 57, which allows the brushes 54, 54a to be equally displaceable and is lifted up by a pair of transformer arms 58, 58 of an automatic formwork reloading mechanism (not shown). To do this, the brushes 54, 54a are pushed outward, and the tips of the brushes 54, 54a are rubbed against the inner circumferential surface of the rising mold 57, thereby adhering to the inner circumferential surface of the mold 57. Grains of sand, dust, and other foreign matter were being brushed away.

なければならないので極めて不都合であつた。 In the case of the above, some of the foreign matter that was rubbed off by the brush may be stuck in the hair of the brush, or it may remain on the hair and be carried on the trolley on the outgoing line with the formwork reloading mechanism. When the brush is moved above the waiting mold and stopped, it receives a slight impact, and this impact causes foreign objects caught in the brush or on top of the brush to fall onto the top of the mold. There is an inconvenience that a part of the melt enters the pouring spout which is open on the upper surface of the mold. Therefore, in the pre-process of forming the mold, a plate is placed to cover the top of the mold, and the plate is removed each time by the operator after the mold reloading mechanism has stopped. This was not only extremely dangerous, but also extremely inconvenient as two workers had to be present to place and remove the boards.

る。 Now, in order to transfer the mold D on the going-out line 3 shown in FIG. The cylinder 33 is started to expand the lifting arms 28, 28 in a V-shape, and upon receiving the signal indicating the end of the operation, the actuating cylinder 33a is actuated to extend the actuating rod 7 by a predetermined stroke length, and the suspended body 8
lower it to the lifting position H. The operating cylinder 33 is activated by the stop signal at this lifting position H.
operates in the opposite manner as described above, retracts the lifting arms 28, 28, and hooks the hooks 29, 29 onto the flange portion I of the formwork D waiting on the cart E, as shown by the chain lines 28a, 28a. After tightening, there is a signal indicating that the lifting is ready due to this tightening.
The operating rod 23 of the brush operating mechanism C shown in FIGS.
and the vertical working surface 24
The corresponding relationship with the roller 22 in contact with the lower end of the oblique action surface 24a connected to the lower part of the roller 22 is shifted from the position shown in FIG. By this operation, the lever 27 is displaced as shown by the chain line 27a, and the actuating plate 15 connected to the lever 27 is rotated as shown by the chain line 15a. The bars 12 and 12a, which are connected via the bars 11 and 11a, are displaced by a predetermined amount inside each of them by a link movement. In synchronization with the starting of the brush operating mechanism C, the operating cylinder 33a in FIG. 5 is started in the opposite direction,
When the formwork D rises to the point where the bars 12 and 12a are retracted inward, and the brushes 13 and 13a reach a corresponding relationship in which they face the lower end of the inner wall surface of the formwork D, the above-mentioned operating rod 23 is activated. Since the movement shifts to the return upward movement, the lever 27 moves due to this fluctuation.
Due to the elastic return of the tension spring 25 and the corresponding relationship between the roller 22 and the oblique action surface 24a, it is instantaneously restored to the starting position shown in FIG. 3B. The brushes 13, 13a released by the above operation reach their original positions, that is, the brushing positions, so that they automatically brush the inner wall surface of the rising form D as described above. At the same time as this brushing starts, the solenoid valve of the air supply source operates to start supplying air, so that sand particles that are scraped off the inner wall surface of the formwork D and fallen onto the foreign matter collection plate 20 due to brushing are removed. Dust and other foreign matter are removed from the surface of the foreign matter collection plate 20 after the formwork D passes upward. When the formwork D that has been brushed by the brushes 13, 13a of the above-mentioned brushing mechanism C reaches the upper limit conversion position G by continuing to rise, the switch actuator supported on the suspension body 8 via the actuating rod 23a 36 contacts the limit switch 37 and stops. The signal from this contact causes the actuating cylinder 33 in FIG.
b is started, and the rail support 6 is connected via the rod 34a.
The suspension truck 35 mounted on the is pulled in the direction of arrow P,
By this operation, the suspension body 8 is moved from the conversion position G to the chain line 8a, that is, above the outbound line 2, and then stopped. This stop signal starts the actuating cylinder 33a and lowers the suspension body 8, and at the same time lowers the actuating rod 23 in the manner described above. The mold D is lowered and placed on the mold A waiting on the trolley E on the forward line 2 so as to cover the surrounding area. Even if shocks or vibrations are applied to the formwork D during operation, the foreign matter caught on the brushes 13, 13a will be reliably collected by the foreign matter collection plate 20. For,
No foreign matter is allowed to fall onto the surface of mold A. In response to the above operation completion signal, the operating cylinder 3
3 operates in the opposite manner as described above to lift the lifting arms 28, 28.
Expand the hooks 2 of each lifting arm 28, 28.
9 and 29 from the flanges I and I of formwork D,
In response to the signal indicating the end of this operation, the suspension body 8 is returned to the conversion position G shown in FIG. go to Further, the other embodiments shown in FIGS.
The air pressure ejected from the horizontally elongated openings parallel to the width direction of the brushes 13 and 13a can blow off all foreign matter that has entered the surfaces and bristles of the brushes 13 and 13a, making it possible to replace the suspension body. It is possible to prevent foreign matter from scattering from the brushes 13, 13a and entering the spout of the mold A during the movement of the mold A.

落下を確実に防止できる。(1) The formwork automatic cleaning device suspended from the suspension body is equipped with a foreign object removal means that combines a foreign object collection plate and a compressed air nozzle. Even if a foreign object gets caught in the bristles of a moving brush or has hair attached to it and falls due to shock or vibration caused by the movement of the suspended body, all the foreign objects will be kept on the foreign object collection plate. It is possible to reliably prevent it from being collected and falling onto the surface of the mold or pouring spout.

は極めて大きい。(3) Unlike conventional methods, during brushing of the inner wall of the formwork, the relationship between the air pressure and the inner wall of the formwork that momentarily rises and passes around the brush is used to remove foreign matter onto the foreign matter collection plate. The clever construction that ensures the collection of foreign matter prevents foreign matter from entering the mold spout, and is extremely effective in eliminating almost no defect rate due to foreign matter entering the mold spout.
