Abstract

To provide a apparatus for processing an object by projecting shots thereon that can be downsized and can use shots of appropriate sizes. A pressure tank 42 is disposed below a position 24 X where an object to be processed 12 is projected. The shots that have been projected are received by the tank 42 . The discharging portion of the tank 42 is communicated with a device for projecting shots. One end of a piping for transporting air for a discharge 54 that can suction shots is connected to a position between the position 24 X and the tank 42 . The other end of the piping 54 is connected to a separator 68 . The separator 68 is connected to one end of the piping for transporting air for a supply 76 that can suction shots. The other end of the piping 76 is communicated with the room for projecting the shots 16.

First claim

The invention claimed is:

1. An apparatus for processing an object by projecting shots thereon comprising:
a device for projecting shots onto an object to be processed that is located in a room for projecting the shots,
a pressure tank being disposed below a projecting position where the object is projected by the device, the pressure tank receiving shots that have been projected, the pressure tank being configured to be pressurized inside, the pressure tank having an outlet that is communicated with a route for supplying the shots in the device;
a first piping having one end that is disposed between the projecting position and the pressure tank, the first piping being able to suction the shots near the one end;
a separator being connected to the other end of the first piping, the separator separating and removing foreign substances from a mixture containing the suctioned shots and powdery foreign substances, the separator discharging the mixture other than the foreign substances through a discharging port, wherein the foreign substances have particles that have different sizes than those of the shots;
a second piping having one end that is connected to the discharging port of the separator, the other end being located above the pressure tank and communicated with a space that is connected to the pressure tank, the second piping being able to discharge the shots from the other end,
wherein at the other end of the first piping an ejector is provided to cause gas to flow into the first piping toward the other end, and at the one end of the first piping a suction piping and a container-like receiver that receives shots below the suction piping are provided, wherein the suction piping is almost horizontally disposed in the room for projecting the shots and has a plurality of holes on the outer circumference of the piping, which holes open downwardly.

2. The apparatus for processing an object by projecting shots thereon of claim 1 ,
wherein a hopper for receiving shots that have been projected is disposed between the projecting position and the pressure tank and the one end of the first piping is connected to the hopper.

3. The apparatus for processing an object by projecting shots thereon of claim 1 or 2 ,
wherein an upper cover is provided above the suction piping, which cover covers the upper portion of the suction piping in the room for projecting the shots and is shaped as an inverted Vin a cross-section perpendicular to the axis of the suction piping.

4. The apparatus for processing an object by projecting shots thereon of claim 3 ,
wherein the one end of the first piping outside the room for projecting the shots is connected to a piping for introducing fresh air, wherein fresh air outside the room for projecting the shots can be introduced into the first piping through the piping for introducing fresh air.

5. The apparatus for processing an object by projecting shots thereon of claim 1 or 2 , further comprising:
a box that constitutes a room other than the room for projecting the shots and that is communicated with the room for projecting the shots, wherein the other end of the second piping is connected to the box.

6. The apparatus for processing an object by projecting shots thereon of claim 1 or 2 , further comprising:
a tank for resupplying shots and;
a third piping having one end that is connected to a discharging portion of the tank for resupplying shots and the other end that is disposed in a space above the pressure tank to be communicated with the pressure tank, wherein the third piping can discharge the shots from the other end.

7. The apparatus for processing an object by projecting shots thereon of claim 6 , further comprising:
a box that constitutes a room other than the room for projecting the shots and that is communicated with the room for projecting the shots, wherein the other end of the third piping is connected to the box.

8. The apparatus for processing an object by projecting shots thereon of claim 1 or 2 , further comprising:
a door that is provided to a gate for carrying the object to be processed in and out of the room for projecting the shots; and
a fourth piping that has one end to be disposed below the door and another end that is disposed in a space that is located above the pressure tank and that is communicated with the pressure tank, wherein the fourth piping can discharge the shots from the other end.
