Is a tool frame, 13b is a deburring tool, and 13c is a guide member.

Of these, the supporting devices 5a and 5b are arranged at two adjacent positions along the conveyor 4 which is a line for conveying the casting rough material 1, and the manipulator 12 has two supporting devices 5a and 5b. It is formed so as to be movable between the supporting devices 5a and 5b (the position after the movement is indicated by a chain double-dashed line in FIG. 1) so as to face each other.

The supporting devices 5a and 5b are, as shown in detail in FIG. 3 by extracting this portion, supporting bases 6a and 6b, frames 7a and 7b, lifting cylinders 8a and 8b, tilting cylinders 9a and 9b, and lifting frames. It has 10a, 10b and guide wheels 11a-11d.

The elevating frames 10a and 10b are guided by the guide wheels 11a to 11f and are vertically movable along the frames 7a and 7b.
This lifting is performed by driving the lifting cylinders 8a and 8b.

The supports 6a and 6b are used for the lifting frame 10
The support bearing 1 is a member that moves up and down integrally with a and 10b, and its base end is fixed to the lifting frames 10a and 10b.
4a and 14b are rotatably attached, and are normally held in a horizontal plane and tilt cylinders 9a and 9b.
Is formed so that it can be tilted as indicated by the arrow in the figure. Further, the support bases 6a and 6b are formed in a saw-tooth shape and are located below the casting rough material 1 suspended on the hanger 2 which is transported on the transport line, and the lifting frame 10 is also provided.
When the a and 10b are raised, the lower surface of the casting rough material 1 is brought into contact with and the casting rough material 1 can be placed.

As shown in FIGS. 1 and 2, the manipulator 12 holds the deburring device 13 via the arm 12a thereof, and the operator 15 operates the deburring device 13 to operate the rough casting material. Remove the burr of 1. The deburring tool 1 as well as the tool gripped by the manipulator 12
3 as well as tools such as a folding machine 17, a plasma fusing machine 18 and a hammer 19 held on a tool stand 16 as shown in FIGS. 4 (a) to 4 (c), and the necessary tools can be used as appropriate. It is configured so that it can be grasped and can be operated remotely to perform a predetermined work.

FIG. 5 is an enlarged view showing the deburring device 13 extracted and enlarged. As shown in the figure, the deburring device 1
3, the base end of the tool frame 13a is attached to the arm 12a via a vibration-proof rubber 20 which is a bending member, and the deburring tool 13b is attached to the tip of the tool frame 13a.
At the same time, a guide member 13c is attached.

Thus, at the time of deburring, the guide member 13
Since the guide member 13c is slightly bent by bringing the tip of c into contact with the surface of the casting rough material 1, the surface shape of the casting rough material 1 can be imitated by the guide member 13c by utilizing this bending (at this time, The contour line is indicated by a dotted line in the figure), and the deburring tool 13b can be used to easily remove the burr 1a.

FIG. 6A is an enlarged view showing the hanger 2 and its vicinity in an extracted and enlarged manner. As shown in the figure,
A rail 22 is fixed to the support bracket 21, and a hanger 2 is hung on the rail 22 via a roller 23. The hanger 2 moves along the transfer line by transferring the chain 3 with a sprocket (not shown). Further, the hanger 2 in the present embodiment is configured to prevent swinging by being clamped by the clamper 24. That is, the clamper 24 is fixed to the support bracket 21, and its lower portion is formed so as to be openable and closable in a vertical plane as shown in FIG. The hanger body 2b is held by the portion 24a.

The operation of the above-described embodiment will be described together with the mode at the time of predetermined work using the same.

First, in the system of the above embodiment,
Since the manipulator 12 has two supporting devices 5a and 5b and the manipulator 12 can move between them, as shown in FIG. 7, with respect to the casting rough material 1 on the downstream side of the transfer line,
For example, a predetermined operation such as deburring is performed, and then the same operation is performed on the upstream casting rough material 1. As a result, the work can be performed efficiently without changing the posture of the arm 12a of the manipulator 12. Incidentally, it takes a relatively long time of about 5 seconds to change the posture of the arm 12a.

In the above-mentioned predetermined work, the casting rough material 1 is attached to the support base 6
It is carried out in a state of being mounted on a and 6b. That is, the raising and lowering frames 10a and 10b are raised with the casting rough material 1 positioned above the support bases 6a and 6b, and the support bases 6a and 6b are moved.
By contacting the lower surface of the casting rough material 1 with the casting rough material 1
Is placed on the supports 6a and 6b.

At this time, as shown in FIG. 6, the clamper 2
The hanger 2 is clamped by 4 to stabilize the attitude of the casting rough material 1.

Further, it can be automatically detected by a sensor that the support bases 6a and 6b are in contact with the lower surface of the casting rough material 1. For example, it can be detected by an inclination sensor that detects the inclination of the supports 6a and 6b.

The operator 15 operates the manipulator 12 to perform a predetermined work with the casting rough material 1 placed on the supports 6a and 6b. At this time, small pieces such as burrs removed from the casting rough material 1 are removed. It drops onto the conveyor 4 below through the gap between the slub-shaped supports 6a and 6b. On the other hand, a removal piece such as a sprue which does not fall is dropped onto the conveyor 4 by inclining the support bases 6a and 6b.

[0038]

As described above in detail with reference to the embodiments, the present invention has the following effects.

(1) By placing a casting rough material which is suspended on a hanger and whose posture is not fixed on a supporting device, it is possible to carry out a predetermined work such as deburring in a stable posture.

(2) Since the manipulator can perform a predetermined work, the worker can perform the work in a safe place remote from the casting rough material.

(3) Since there are two work stations, efficient work can be achieved.

(4) Since the supporting table is made in the shape of a saw, it is easy to dispose of the cast small pieces removed.

(5) During deburring, the tool follows the surface of the rough casting material, which facilitates the work.
