Abstract

An improved unloading apparatus for a plate-like workpiece cutting machine includes a platform, a faceplate, a lift device, and an intermediate member. The platform is provided with a channel recessed downwards from a top side thereof. The faceplate is mounted on the top side of the platform to seal the channel for putting to-be-machined plate-like workpieces thereon and is provided with a plurality of through holes. The lift device is mounted below the faceplate and includes a power unit and a supporting member, which can be driven to be lifted and lowered by the power unit. The intermediate member is disposed with a plurality of locating columns corresponding in locations to the through holes of the faceplate and is mounted on a top side of the supporting member.

Claims

1. An unloading apparatus for a plate-like workpiece cutting machine, said unloading apparatus comprising:

a platform having a channel recessed downwards and a base fixedly mounted at a bottom side of the platform;

a faceplate having a plurality of through holes and mounted on a top side of said platform to seal said channel for putting plate-like workpieces on said faceplate;

a lift device mounted below said faceplate and having a power unit installed in said base and a supporting member driven to be lifted and lowered by said power unit, said supporting member having a top portion, a shaft extending downwards from said top portion said top portion extending transversally outwards with respect to a top end of said shaft, and a bottom portion extending transversally outwards from a bottom end of said shaft and having at least one guide hole and at least one guide bar running through said at least one guide hole, said guide bar is fixedly mounted to said base; and

an intermediate member mounted on the top portion of said supporting member and provided with a plurality of locating columns in corresponding locations to said through holes of said faceplate.

2. The unloading apparatus as defined in claim 1, wherein said power unit is a pneumatic cylinder having an arbor connected with said supporting member.

3. The unloading apparatus as defined in claim 1, wherein said base has a topside member positioned between said top portion and said bottom portion of said supporting member, said topside member having an axial hole at its center and said shaft extending through said axial hole.

4. The unloading apparatus as defined in claim 1, wherein said bottom portion of said supporting member has three of said guide holes spaced apart from one another at an identical interval, and three said guide bars extending through said guide holes.

5. The unloading apparatus as defined in claim 1, wherein said intermediate member has a plurality of embedding holes at a top side thereof, said embedding holes being in corresponding position to said through holes of said faceplate, and bottom ends of said locating columns fixed in said through holes.
