DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work reversing device for rotating a work and visually inspecting the work.

[0002]

2. Description of the Related Art For example, a cylinder head of a cast engine is machined on a cylinder block joint surface, a head cover joint surface, an intake manifold joint surface, an exhaust manifold joint surface, and the like. Conventionally, when inspecting the work surface of such a work, an operator visually inspects the work while lifting the work by hand on a work table and inverting the work.

[0003]

However, there is a problem that a lot of labor is required to lift and invert the work by hand as in the prior art, and the burden on the operator is large.

The present invention has been made in view of the above circumstances, and has as its object to provide a work reversing device capable of easily performing a reversing operation for visually inspecting a work.

[0005]

According to the first aspect of the present invention, a work is inserted between a plurality of guide rails of a rotary drum from an inlet opening of an inlet side end plate, and the rotary drum is guided by guide rollers. By rotating, the visual inspection can be easily performed with the desired surface of the work facing the operator. After the inspection, the work is discharged from between the guide rails through the outlet opening of the end plate on the outlet side.

According to the second aspect of the present invention, when the work is supplied / discharged to / from the rotary drum, the arm of the worker can be moved through the cutout of the entrance end plate or the exit end plate. The worker's arm does not interfere with the entrance-side end plate or the exit-side end plate, thereby improving work efficiency.
