DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a workpiece by injecting a molten material into a cavity formed by joining a fixed mold and a movable mold, and combining the fixed mold and the movable mold. The present invention relates to a deburring method and a deburring apparatus for removing a burr formed on a surface in a thin plate shape and connected to the workpiece.

[0002]

2. Description of the Related Art Conventionally, when a work is generally cast in mold casting, a thin plate-shaped burr is formed on the mating surface of a movable mold and a fixed mold so as to be continuous with the work. Such burrs have to be deburred immediately after casting of the work in order to make the positioning of the work accurate when processing in a subsequent processing step, and conventionally, the work is carried by a transfer robot. A deburring robot equipped with a deburring tool is moved by a teaching function or numerical control, etc., against the workpiece placed and positioned to remove burrs formed on the workpiece and to remove workpieces that cannot be removed. On the surface side, another robot for changing the posture of the work has changed the standing posture of the work one by one before executing deburring.

[0003]

According to the conventional method of deburring a work, a work transfer robot and a work transfer robot are provided.
There is a problem that a deburring robot and a work posture changing robot are required, and the equipment becomes large. The present invention eliminates such conventional problems by eliminating deburring.
A transfer area for transferring the work is provided in addition to the deburring area provided with the robot, and a deburring tool is installed at one location in this transfer area to transfer the work from the transfer area to the deburring area. During the deburring, a part of the work is deburred, the change in the posture of the work in the deburring area is reduced, the deburring operation is quickly performed, and the entire equipment is downsized. is there.

[0004]

Effects of the Invention The present invention, As described above, <br/> deburring provided deburring robot from the transport region in which a transfer robot for transferring the workpiece facing the part of the deburring area Before transporting the workpiece to the area, a part of the workpiece was deburred by a first deburring tool which was provided in the transport area and operated in a deburring manner as previously stored, and this deburring was performed. was transferred from the transfer area the workpiece by the conveying robot to the deburring area, the part of the work by the second deburring tool with deburring robot operating deburring as it was previously stored in said deburring area since to carry out the deburring, on the way from the conveying area of the work of the transport to the deburring area, performs up of part of the work burrs, the figure of the workpiece in the deburring area To reduce the change, quickly it is possible to perform the deburring work.

The first deburring tool provided in the transfer area is fixed to a base, and the transfer robot holding the work removes a part of the burr of the work with the first deburring tool. since to carry out the deburring movement as stored in advance as the first deburring tool is simplified and cost due to the provision of the first deburring tool it will not be a problem.

In addition, the work which has been deburred in the transport area and the deburring area is inspected by an inspector on an inspection line provided so as to face a part of the transport area and the deburring area. In the area where the deburring by the second deburring tool provided to the deburring robot is incomplete, the incomplete part is deburred by the second deburring tool in the middle of the inspection line. As a result, it is not necessary to convey a work having an incompletely deburred portion to the deburring area, thereby improving the efficiency of the deburring operation.

In addition, the work which has been incompletely deburred by the first deburring tool in the transport area in the inspection by the inspection line is gripped by the transport robot at the end of the inspection line, and Since the workpiece is conveyed to the first deburring tool and the deburring of the incompletely deburred portion is performed, when the deburring is completed, the workpiece held by the transport robot is stored in the storage unit. The efficiency of deburring work is improved.

Further, the workpiece is gripped and moved from the transport area.
Before transporting to a deburring area provided with a deburring robot, a transport robot that moves as previously stored so as to remove a part of the burrs of the gripped work, and one of the burrs of the workpiece gripped by the transport robot. A first deburring tool provided in the transport area to remove a part of the deburring of the work by moving as previously stored so as to remove the part, a deburring robot having a second deburring tool which operates deburring as it was previously stored to remove a portion from the transfer region by the transfer robot burr formed on the workpiece which is conveyed into the deburring area, the provided so as to face a part of the transport region and deburring area, it becomes more and inspection lines for inspecting the deburring is the work by the transport region and deburring area, the inspection Bali is in the middle of the Inn up incomplete箇
Since the work input device is provided with a work deburring device, a change in the posture of the work in the deburring area is reduced, and a deburring operation is quickly performed, and a robot for changing the work posture becomes unnecessary. The entire equipment can be reduced in size.
