[Prior art and problems]

 To remove a casting from a conventional sand mold with a frame, pull out the upper frame from the state where the upper and lower molds are combined, separate and remove from the lower frame, and collapse the upper sand mold at the upper part of the lower frame to cast. The product is exposed and the exposed cast product is grabbed by the clamp device and taken out. The removal of such a cast product had a problem that the sand mold collapsed when the upper frame was pulled out, and the cast product could be displaced due to the collapse of the sand mold, making it impossible to grasp the cast product with the clamp device. ..

As another method, in a state where the sand molds with the frame are vertically aligned, the sand mold is extracted from the casting frame, and the extracted sand mold is moved to the casting product take-out position, There is also a method in which the sand casting mold is grasped and taken out together with the sand casting mold at the position, but in this case the sand casting mold is collapsed because the sand casting mold is moved or stopped after the sand casting mold is pulled out from the flask. However, there is a problem that the cast product is misaligned, and the position of the cast product is displaced as in the case of the above, and the clamp device cannot hold the cast product. The present invention has been made in view of the above problems, and an object of the present invention is to provide a casting product takeout device that can reliably grab and take out a casting product.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. A hollowing roller conveyor 3 is provided via frames 2 and 2 standing on a base 1, and an upward cylinder 4 is provided below the hollowing roller conveyor 3 and At the tip of the piston rod 5 of the cylinder 4, a pull-up table 8 is fixed which can be inserted into the upper and lower casting frames 6 and 7 which move intermittently on the hollowing roller conveyor 3. Above the hollowing roller conveyor 3, there is disposed a stopper 10 for preventing the upper and lower casting molds 6, 7 from rising up through the mounting frames 9 on the frames 2, 2, and the lower surface of the stopper 10 is The heights of the upper and lower flasks 6 and 7 placed on the hollowing roller conveyor 3 are set so that they can move and pass with a slight gap.

A frame frame 11 extending in a direction intersecting the longitudinal direction of the hollow roller conveyor 3 is provided above the hollow roller conveyor 3, and the frame 11 is mounted on the frame 11. A carriage 12 that is reciprocally moved in the longitudinal direction is arranged. A mounting plate 13 is suspended below the dolly 12 via arms 14 and 14, and a rotating frame 15 is attached to the end of the mounting plate 13 on the delivery side of the dolly 12 (the left end in FIG. 1). One end is rotatably connected. A tip of a piston rod of a cylinder 16 rotatably attached to the attachment plate 13 is pin-connected to the center of the rotating frame 15, and the rotating frame 15 is normally placed in a horizontal state. ing.

A mounting frame 18 is hung horizontally below the rotating frame 15 via an arm 17. The mounting frame 18 has upper ends of two clamp claws 19 and 20. It is mounted so as to face the moving direction of the carriage 12 and to be rotatable in the same direction. Arms 19A and 20A are attached to the upper ends of the clamp claws 19 and 20 in a state of being inclined and projected upward, and an opening / closing cylinder 21 is attached to the upper end of the arm 19A. The tip of the piston rod is connected to the upper end of the arm 20A. That is, the clamp claws 19 and 20 are opened and closed by the operation of the open / close cylinder 21.

On the lower surface of the carriage 12 on the feeding side (right side in FIG. 1), a push-out plate 22 corresponding to the right outside position of the sand mold M that has been pulled up is provided with a frame 23 that reaches a position slightly above the stopper 10. Suspended through. Further, a chute 24 for guiding the carry-out of the sand mold M is provided on the delivery side (left side in FIG. 1) of the truck 12 in the Stoch 10. In the figure, 25 is a sand treatment facility.

In the case of such a configuration, the opening / closing cylinder 21 contracts and operates in the state of FIG. 1 to open the clamp claws 19 and 20 and stand by. In this state, the upper and lower flasks 6 and 7 containing the sand mold M that has been poured are stopped at positions directly above the pull-up table 8 in the hollow roller conveyor 3. Next, the upward cylinder 4 is extended and the pulling table 8 pulls up the sand mold M from the upper and lower flasks 6 and 7 in the state shown by the broken line. At this time, the upper and lower flasks 6, 7 are prevented from rising by the stopper 10. Next, the opening / closing cylinder 21 is extended to close the clamp claws 19 and 21. By this operation, the clamp claws 19 and 20 securely clamp the bite-in cast product W inside the sand mold M which has been pulled out and is not displaced.

Next, the cylinder 16 is extended to rotate the rotating frame 15 until the rotating frame 15 reaches a vertical state. As a result, the cast product W clamped by the clamp clamps 19 and 20 is pulled out of the sand mold M and rotated by 90 degrees, while the sand mold M is partially destroyed and the sand treatment facility is run through the shoot 24. It is dropped to 25. In this state, a drive device (not shown) of the truck 12 operates to move the truck 12 to the left. By this operation, the destroyed sand mold M on the pull-up table 8 is pushed by the push-out plate 22, pushed out on the chute 24 and dropped to the sand treatment equipment 25. On the other hand, the cast product W clamped by the clamp claws 19 and 20 is moved to a position directly above the transfer device (not shown), and the clamp is released by the contraction operation of the opening / closing cylinder 21 and transferred to the upper part of the transfer device. During this time, the upward cylinder 4 is reversely operated to lower the lifting table 8 to the position shown in the figure. Next, the cylinder 16 is contracted to reverse the clamp claws 19 and 20 by 90 degrees, and then the drive device of the carriage 12 is reversely operated to return the carriage 12 to the state shown in the figure, and the above-described operation is repeated. Is.

As is apparent from the above description, the present invention provides a clamp claw that can be inserted and removed above the sand mold lifting table, and clamps the casting in the sand mold with the clamp claw while the sand mold is being lifted. By doing so, it becomes possible to clamp the cast product accurately, and there is no inconvenience that the clamp of the cast product will come off. Therefore, it is remarkable that the cast product can be reliably taken out and can be automatically transferred to the next process.
