56 is a limit switch for confirmation, and 56 is a backer 1 and L de-staining soda B in cooling/form-breaking fins.
This is a limit switch installed on the downstream side of the backer to confirm the withdrawal of the backer.

The present embodiment is fused as described above, and its operation will be explained below. First, to explain the mounting of the backer C, which acts as the pouring fin 1, onto the facing A volume 2, the clamp arm 17 of the automatic backer mounting machine clamps the backer Cf, and the swivel table 5 rotates to the backer mounting position E. Then, attach the backer C to the part 2a of the flask 2, which is the frame tightening point.
The backer was automatically installed (when the backer installation command was issued on the 4th), the slide cylinder 14 was extended and moved forward to move the carriage 11 forward, so it was clamped by the clamp arm 17. The upper and lower clamp claws 34 and 35 of the cutter C are positioned so as to sandwich the flange 2a of the frame 2 from above and below.

Subsequently, the rotary tool 26 is rotated in a predetermined tightening direction a by the air motor 27, and the rotary tool 26 is lowered together with the elevating body 24 through the nd cropping proboscis of the elevating shaft lifter 25, and the clutch cylinder 68 of the backer 〇 is lowered. The rotating shaft 66
In order to rotate the cast iron, the movable clamp claw 35 is lowered via the surface-clamping cam machine tank 67, and the flanged portion 2a of the cast iron 2 is clamped by the movable clamp claw 35 and the fixed clamp claw 34.

When the frame tightening is completed in this way, the air motor 27 is stopped, the lifting cylinder 25 is extended and the rotary machine 426 is raised and returned together with the lifting body 24, while the ramp cylinder 20 is contracted and the clamp arm 17 is moved. Open and hold backer C to I'11. Subsequently, when the slide cylinder 14 is retracted and the clamp arm 17 is moved backward together with the carriage 11, the swing cylinder 7 is retracted and the swivel base 5 is rotated by 90 degrees.
At the same time, the clamp arms 1 and 17 are moved to the backer receiving position (2), and the clamp arms 17 are left open and on standby. In this state 9, when the lifter tape/L150 for carrying out carrying the backer C is lowered by the lift cylinder 51, the extrusion cylinder 54 is extended and the pressure plate 56 is moved to the top of the lifter tape μ50.
Move C onto the backer receiving plate 62 of the automatic 7W 414 D.

That is, the backer C has both clamp arms 1 in the open state.
Then, when the clamp cylinder 20 is extended and the clamp arm 17 attaches the backer Cf, the swivel shaft 7 is extended and rotates the swivel base 5 by 90 degrees. The backer Cf held by the clamp arm 17 is displaced to the position E.

Thereafter, by repeating the above-mentioned operation using the backer self-IQ mounting machine, the backer Cf is mounted on each ridge 2 on the pouring fin 1 which is intermittently transferred.

The flask 2 that has passed through the backer attachment tube KF is checked by the limit switch 55 to have 71 bag layers, and if the backer C is not attached, the line is stopped.

Next, we will explain the 71 dimensions of the cooling and deforming fin 6.
Detachment (C will be explained. - When the frame 2 reaches the 71st cast station B, the clamp arm 17 of the backer 16, which was waiting at the backer 16 detachment Ml), moves the clamp arm 17 of E to the casting flask 2. Nokutsuka c'If installed on:
It moves forward together with the carriage 11 in an open state 0 to clamp it. Then, when the clamp arm 17 closes at the center end and clamps the backer C, the rotary tool 26 rotates in the loosening direction and moves downward, engaging the clutch cylinder 68 of the backer C and rotating the rotating shaft 66. In particular, the movable pump pawl 65 is raised. When the frame tightening of the flask 2 by the backer C is released in this way, the rotary tool 26 stops rotating and returns to the upper position.

Subsequently, the carriage 11 moves backward and the swivel table 5 rotates 90 degrees, and the backer ○ held by the clamp arm 17 is released from the shell #2 and moved to the backer delivery position ■. Then, as the carriage 11 moves forward at the discussion backer delivery position iff, it is transferred onto the loading lifter tape/l'45 waiting at the lower end. Next, the clamp arm 17 is attached to the backer C.
After releasing the clamp, the carriage 11 moves backward and the swivel table 5
By rotating 090 degrees, it moves away from Backer 〇 and returns to the hacker exit position ■, preparing for the next Backer 14 escape.

It should be noted that the flask 2 which has passed through the backer removal stage 4-B is checked by the limit switch 56 to have left the 71 fins, and if the backer C has not been removed, the fins are stopped.

Next, a description will be given of one piece car return using the piece car return conveyor F. As mentioned above, /1 Tsukar 1-1
After the peeler C is transferred onto the carry-in glue lid tape/L/A5 by the 1#I belly 4NE, it is raised by the extension operation of the lift cylinder 46 of the lifter table 45. Subsequently, the pushing cylinder 48 is extended and the suppressing plate 49 is applied to the lifter tape fv45 (D/'
The feeder C is transferred onto the conveyor V-/L'39, and at this time the feeder 41 is on standby [2] at the reverse end. Note that after the backer C is transferred, the push cylinder 48 and the lifter tape /1/45 are returned to their original positions.

On the other hand, it was transferred onto the transport sea/l159.
The opening 41 of the feed par 41 moves forward when the Cb-f feed cylinder 44 is extended.
The lower end of the rear surface is caught by the feeding force wind 40 protruding from a, and the feed pawl 40 is transferred by a certain amount on the conveyor rail/I/69, and when the feed par 41 moves backward, the feed pawl 40 is attached to the backer C.
It crawls through the underside and returns. In addition, excessive intermittency of the backer C due to the feed par 41 VC is caused by the transfer rate fi/
This is done every time the backer 〇 is placed on top of 69, and the backer 〇 thus transferred is placed at the lifter tape/
1150-'. Then, after # of backer C, the lifter tape /l150 is lowered by the contraction operation of the lift cylinder 51, and at that position, the backer is transferred onto the backer receiving plate 32 of the backer self-a attached RD by the aforementioned extrusion cylinder 54. This is where the action takes place. That is, the backer attaching/detaching device of the present embodiment operates as described above, thereby attaching the backer C to the flask 2 at the pouring fin 1 and removing the backer from the flask 2 at the cooling/molding twin 6. The withdrawal of C, and furthermore, the return of backer C after withdrawal, can be done intentionally.

In addition, in this example, 2)
Backer of the table! Installed a vl equipment, and installed two cars at the backer withdrawal stage B!
If it is possible to arrange the pouring wine 1 and the cooling/deforming fins 6 in close proximity to each other, it is possible to arrange the breakaway machine E between the two fins 1 and 5. It is possible to omit either the automatic attachment machine or the 7/Tsuka self-III market machine, and have one 1MM machine attach backer C to frame 2 and tax 9. .

Effects of the Invention As detailed above, according to the present invention, human power KIlj[l
Since the work of attaching and detaching the holder (to the cast flask) can be done in 111τh using mechanical force, the fin can be unmanned, and the maker can be freed from harsh labor.
