In described size classification apparatus (20), a plurality of rollers are assemblied on the support frame beams (21) of two given width of being separated by, thereby the metallic roll rotation makes metal can advance along direction of advance, and metal can falls from the gap (d) between the roller (22), and the size of the jar of being classified is thus determined by the size in gap.Roller (22) is rotated by the power drive of motor, and is in linkage status by the power transmission such as chain, gear or belt pulley.

Roller (22) has projection (22a), preventing in metal can or the gap of other material plug between roller (22), and the parallel formation of roller (22) on the guiding (23) of projection (22a) and the support frame beams (21).

The size in the gap (d) between the roller (22) is determined by the size such as the target classification object of beverage can.

Described proportion sorter (30) comprises funnel (31), is used for receiving the jar that falls from the gap between the roller (22) of size classification apparatus (20); First exhaust outlet (32) is positioned at the channel bottom of the metal can that falls from funnel, is used to classify and discharges proportion other material of metal species as iron plate and Metal Ball greater than beverage can; Inflow pipe (33) is formed on the channel side wall of the metal can that falls from funnel, allows to be blown into wind from air blast (60), and wind-force is acted on the jar of whereabouts; Second outlet (34) is used for discharging the beverage can by the wind force classification of air blast (60), the direction of the wind that wind-force is blown into along inflow pipe (33); And steam vent (35), be positioned at the opposite of inflow pipe (33), the wind that is blown into from air blast (60) is discharged.

Described vibration classifier (50) as shown in Figure 3, comprises silk screen plate (51), beverage can is transported on the described silk screen plate (51) by second conveying device (40), and the power generating apparatus (that is motor, expression among the figure) that makes the vibration of silk screen plate (51) generation.Described silk screen plate (51) is downward-sloping, thereby other material that is blended in the beverage can that is classified is come out by vibration and location energy separation, and jar is slided from described plate.

Described first, second and the 3rd conveying device (10,40,70) can be conveyer belts.

The present invention has first conveying device (10), and the jar that is used for collecting with recycling is transported to size classification apparatus (20).

The be inclined upwardly height of size classification apparatus (20) of described first conveying device (10).Though conveyer belt preferably as first conveying device, uses other available device also to be fine.

In size classification apparatus (20), a plurality of rollers (22), and are rotated along the metal can direction of advance in supported on both sides by two support frame beams (21).

Roller (22) drives rotation by the rotary power of motor, and is connected by chain, gear or belt pulley.Therefore, each roller is related rotatablely moving, and carries thereby make metal can pass through them.

The structure of size classification apparatus (20) allows metal can to fall by the gap between the roller (22).The size in the gap (d) between the roller (22) is by the size decision of target classification object such as beverage can.

That is, the structure of size classification apparatus makes beverage can or less object fall from the gap between the roller (22), than beverage can big the jar then by the conveying that rotatablely moves of roller (22), be discharged into pulverizing process.

The set a roof beam in place structure of (21) of stand frame is downward-sloping, is convenient to the conveying of metal can.

The surface of roller (22) has projection (22a), and when jar or other material plug were between roller (22), jar or other material that projection (22a) can will clog in the rotary course of roller (22) were taken away.Guiding (23) makes jar or other material face roller (22) with preferred direction in the rotary course of roller (22).

In proportion sorter (30), funnel (31) is contained in roller (22) below, is used for receiving on the whole area that support frame (21) forms the jar that falls by the gap between the roller (22).First exhaust outlet (32) be formed on funnel under, it is great in the sheet metal of beverage can be used for delivery ratio.Second outlet (34) is positioned at the side of first exhaust outlet, is used to discharge the less jar of proportion, as beverage can.The structure of inflow pipe (33) makes the wind that blows out from air blast (60) space, whereabouts to metal can, thereby wind-force is acted on the jar of whereabouts, according to their proportion they is discharged from first or second outlet.

Steam vent (35) is formed on the opposite of inflow pipe (33), thereby can discharge the wind that is blown into from inflow pipe (33).

Have second conveying device (40) in second outlet (34) below, will be transported on the vibration classifier (50) from the beverage can that second outlet (34) is discharged.

Described second conveying device (40) is conveyer belt preferably, but other available device also is fine.

The structure of vibration classifier (50) is the silk screen plate (51) of sieve type, and by the dynamic vibration of motor.Therefore, the metal can that silk screen plate (51) is carried second conveying device (40) sieves, thereby other material is sieved to the bottom.

And, because silk screen plate (51) is downward-sloping, so the vibration of hang plate makes metal can be transported to follow-up pulverizing process.

First, second and the 3rd conveying device (10,40,70) are conveyer belts, and can have the side guiding that prevents that fragment from falling in its both sides, and have a plurality of projections on belt surface, are used for increasing conveying frictional force.

Explain the whole process of sorting beverage can according to the present invention below with reference to Fig. 4.

Roller (22) upside of size classification apparatus (20) is carried and installed to recovery with the jar of recycling by first conveying device (10).

Because roller (22) is rotation simultaneously under the motor power effect, therefore the metal can on roller (22) is carried along the inclined-plane of roller (22).

Because between the roller (22) gapped (d), so can fall from the gap as beverage can little jar or sheet metal, independent crushing system is carried and be discharged into to the jar of large-size then on roller (22).

If in jar or the gap of other material plug between roller (22), then roller (22) may damage and the motor of driven roller (22) will transship, therefore have projection (22a) on the surface of roller (22), be used for jar and other material that roller (22) rotary course clogs are taken away.

Because roller (22) is arranged to downward-sloping, and projection when roller rotatablely moves (22a) was moved to the route on top the end of along, therefore jar and other material of being plugged are clashed in the bottom, are pulled on the plane, top that the upper space by roller forms, and are then carried by roller (22) and discharge.

Because guiding (23) is formed on the head-to-foot route, this is the route that projection (22a) is followed in the motion process being further rotated of roller, so projection (22a) can not act on jar or other material.

If there is not guiding (23), because projection (22a) will be collided jar or other material in the bottom towards the projection (22a) on next roller from the top, thereby can not carry out normal operation, and jar or other material of being plugged will be filled in deeplyer.

Then, the metal can that the gap by roller falls is received by funnel (31), and the wind that is blown into by inflow pipe (33) in passage is moving.

At this moment, iron plate that proportion is bigger and Metal Ball are fallen in first outlet (32) under the minor impact of the wind that inflow pipe (33) is blown into, and the less beverage can of proportion is then blown along the direction of wind-force, and is discharged in second outlet (34).

The beverage can of discharging from second outlet (34) drops on second conveying device (40), and is transported to vibration classifier (50) by second conveying device (40).

Beverage can is installed in the upside of silk screen plate (51) after the conveying of the sorting of passing through size classification apparatus (20) and proportion sorter (30) and second conveying device (40), under the vibration of plate, beating and carrying, be transported to the subsequent processing of crushing system then.

By beating that the vibration of silk screen plate (51) causes, make other separating substances of mutual mixing come out and slave plate (51) in fall.

Therefore, separated the going out of other material of small size of nonmetal and metal species only has the metal can that is equal to or less than beverage can be sorted out as the final target object that reclaims.

Fig. 5 represents another embodiment of size classification apparatus (20).

In the structure of another embodiment shown in Figure 5, have downward-sloping support frame (201) with and the direction of advance of upper edge jar is arranged and roller by the CONTACT WITH FRICTION rotation, and also comprise the vibrating device (not shown) that makes support frame (201) vibration by power generation arrangement in the structure such as motor.

Similarly, as the embodiment of front, the gap size between the roller (202) (d ') determine by the size of target object of being classified such as beverage can.

Metal can installs to the upper surface of roller (202), then Support frame (201) vibration so that jar along downward inclined-plane to lower slider.In lower slider, the gap that metal can passes between roller (202) according to its size falls.

Because roller (202) is not by power drive rotation, but by the frictional force rotation, therefore when jar by gap (d '), adjacent roller rotates in opposite direction so that jar passes through, and has reduced the obstruction between the roller (202).

And roller (202) can be replaced by the hold-down bars that does not rotate.

Like this, jar is transported to proportion sorter (30) and carries out subsequently processing.

Explain the work of the crushing system be used to pulverize the jar that sub-elects by categorizing system below with reference to Fig. 6 to 10.
