The rear end portion is a processed material input portion 43, and the processed material input portion 43 is located further rearward than the rear wall portion 23 of the accommodating portion main body 20. In the processing object input portion 43, the bottom portion 36 gradually rises from the front side toward the rear side, and the rear wall portion 33 is formed at the rearmost portion thereof. The front end portion of the conveyor 30 is a processed material outflow portion 44, and the processed material outflow portion 44 is located further forward than the front wall portion 24 of the accommodating portion main body 20. The front wall portion is not formed at the forefront portion of the processing object outflow portion 44.

As described above, as shown in FIGS. 2 and 3, the accommodating unit main body 20, the conveyor 30 (excluding the object-to-be-processed-in portion 43 and the object-to-be-treated outflow portion 44) and the chamber 50.
The housing portion 10 is formed by (the lower surface 56) thereof, and the housing portion 10 forms a substantially closed space.

As shown in FIGS. 1 to 3, an air inlet pipe 51 (downstream end thereof) is connected to the upper end of the chamber 50, and a fan 52 is connected to the upstream end of the air inlet pipe 51. There is. High-pressure air is supplied into the chamber 50 via the air inflow pipe 51 by the fan 52.

As shown in FIGS. 2 and 3, the chamber 50
A large number of air ejection pipes 55 (gas ejection portions) are provided on the lower surface 56 of the. That is, the plurality of air ejection pipes 55 are provided in both the width direction and the length direction of the chamber 50. The air ejection pipe 55 extends vertically downward in the accommodation chamber and reaches the vicinity of the bottom portion 36 of the conveyor 30. High-pressure air in the chamber 50 is ejected from the air ejection pipe 55.

An air pressure adjusting plate 53 is arranged inside the chamber 50. As a result, the air pressure of the air flowing in from the air inflow pipe 51 is equalized, and the high-pressure air flows out from each air ejection pipe 55 almost uniformly.

As shown in FIGS. 1 to 3, air is discharged to the upper part of the wall surface on both the left and right sides (the left and right sides with respect to the traveling direction of the workpiece W) of the accommodating portion 10 (accommodating portion main body 20). A hole portion 28 (gas discharge portion) is formed. Air exhaust hole 2
The reference numeral 8 extends along the length direction of the accommodation portion 10 (accommodation portion main body 20) (the traveling direction of the workpiece W).

As shown in FIGS. 1 and 3, an air converging / discharging portion 60 is connected to each air discharging hole portion 28. The width (the length in the front-back direction of the accommodating portion 10) of the air converging / discharging portion 60 becomes narrower from the upstream side to the downstream side (see FIG. 1), and the air discharging pipe 61 (the upstream end) is provided at the downstream end thereof. It is connected. The downstream end of the air discharge pipe 61 is connected to the cyclone 65.

Next, the function and effect of this foreign matter removing device will be described. As shown in FIG. 2 and the like, the object to be processed W is loaded into the object to be processed input section 43 of the conveyor 30,
Are gradually moved forward by the conveyor 30.
That is, the object to be processed W flows into the accommodation unit 10, moves inside the accommodation unit 10, and flows out from the accommodation unit 10. Then, it falls from the processing object outflow portion 44 of the conveyor 30,
It is collected in the collection container 60.

As shown in FIGS. 2 and 3, in addition to the above-described operation, the high-pressure air flows from the fan 52 into the high-pressure chamber 50 through the air inflow pipe 51, and the high-pressure air is discharged from the air ejection pipe 5.
5 is ejected into the accommodation unit 10. As a result, the object W to be processed on the conveyor 30 is agitated (to be precise, the object W to be treated is gradually moved forward as described above while being agitated). Also, the atmospheric pressure in the housing section 10 becomes high,
As shown in FIGS. 1 and 3, from the inside of the housing portion 10 through the air discharge hole portion 28, the air convergence discharge portion 60 → the air discharge pipe 61
→ An air flow toward the cyclone 65 occurs.

Therefore, the foreign matter S (having a relatively small weight) mixed in the object W to be processed flies up and is discharged together with air from the air discharge hole 28. The object W (most of them) does not reach the air discharge hole 28 due to its weight. so,
The air pressure of the air jetted from the air jet pipe 55 is set.

The air containing the foreign matter S flows through the air converging and discharging portion 60, the air discharging pipe 61, and the cyclone 65. Then, from the lower end of the cyclone 65, the foreign matter S
Flow out, and the air flows out from the upper part of the cyclone 65.

As described above, the foreign matter removing apparatus can easily remove the foreign matter S from the object W to be processed. Further, since the foreign matter removing device removes the foreign matter S while moving the workpiece W by the conveyor 30, it is possible to efficiently remove the foreign matter S from a large amount of the workpieces W in sequence.

The above description is merely one embodiment of the present invention, and it is needless to say that the present invention can be implemented in a mode in which various modifications are made based on the knowledge of those skilled in the art.

For example, in the above embodiment, the housing portion 10
The air inside the air converging and discharging section 6 is based on its own high atmospheric pressure.
Although the air is discharged from 0, a mechanism for positively sucking and discharging the air in the housing portion 10 may be provided.

Further, the foreign matter removing apparatus of the present invention need not have the conveyor (30). In that case, so-called batch processing is performed. That is, the object to be treated is accommodated in the accommodating portion (10), high-pressure air is jetted into the accommodating portion (10) for a predetermined time, and the foreign matter S is removed.
After that, the object to be processed is taken out from the accommodation section (10).
When processing a large number of objects to be processed, the work is repeated.
