[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a vibrating sieve for sorting cans and bottles of the present invention according to an embodiment will be specifically described with reference to the drawings.

FIG. 1 is a perspective view of a vibrating sieve 1 for sorting cans and bottles according to an embodiment, FIG. 2 is a partially cutaway side view, FIG. 3 is a plan view, and FIG. 4 is a front view.

The vibrating sieve 1 for sorting cans and bottles is shown in FIGS.
With reference to the column 17 of the frame 18 fixed to the floor surface.
The front and rear of the main body 11 are supported via a coil spring 16, and important parts of the main body are reinforced by ribs 12 </ b> R and angle members 12 </ b> A. Vibration motors 15 are symmetrically attached to the outer surfaces of the side walls 14 on both sides of the main body 11 at a predetermined inclination angle. The vibration motor 15 has a well-known structure having unbalanced weights at both ends of a rotating shaft.
5 is synchronously rotated in the opposite direction, the centrifugal force of both rotations is combined, and the arrow m
Is given, and the cans C and bottles B put into the main body 11 are transferred in the direction shown by the arrow p.

In the main body 11, a can C containing newspapers P and magazines M at a height lower than the upper end surface of both side walls 14,
An input surface 31 into which bottles B are charged is formed, and subsequently, an upstream sieve surface 41 in which a plurality of round bars 42 are arranged in the transfer direction with openings that cans C and bottles B do not drop is connected. Have been. That is, the width 800 mm between both side walls 14 is equally divided, and 13 round rods 42 are arranged in parallel in the transport direction to form an upstream sieve surface 41, and the round rods 42 are pipes extending between both side walls 14. 43 is welded and supported on a tapered vertical support plate 44 fixed at equal intervals to the outer peripheral surface of the base plate 43.

Further, a vertical guide having an inclined plate 45a or 45b integrally formed at the upper end at a position corresponding to every third opening from the side wall 14 from the input surface 31 to the upstream sieve surface 41. A member 47 is provided, and is fixed to the input surface 31 with a bolt 47b. The surfaces of the newspapers P and magazines M to be thrown in from the upper side are directed parallel and perpendicular to the transport direction so as to easily fall from the upstream sieve surface 41. Further, a downward step 46a or 46b is formed on the upper end surfaces of the inclined plates 45a and 45b, respectively. For example, a newspaper P /
When there are magazines M, when they reach the step 46a, their weight balance is lost on both sides and they slide down to the side wall 14 side.

Subsequently, the can C
A gap 48 where bottles B do not fall is provided, and a step 48 is provided downward from the upstream sieve surface 41. Like the upstream sieve surface 41, the downstream sieve surface 51 formed by the round bar 52 is formed. They are connected with half an opening. That is, the downstream sieve surface 51 is formed by arranging the 14 round bars 52 positioned at the center of each of the openings formed by the side walls 14 and the 13 round bars 42 on the upstream side in parallel with the transfer direction, The round bars 52 are welded and supported at equal intervals on the outer peripheral surface of a pipe 53 stretched between the side walls 14 at a tapered triangular vertical support plate 54 fixed in a direction opposite to the upstream vertical support plate 44. . Naturally, there is an opening between the round bars 52 so that the cans C and the bottles B do not fall. The reason why the round bar 42 and the round bar 52 are separated from each other by a half-opening is that when there are newspapers P and magazines M transported across the round bar 42, the newspapers P and magazines M are transferred to the round bar 52. This is to allow the vehicle to fall downward without being transferred to.

Further, the step 48 is provided between the downstream end of the upstream sieve surface 41 and the upstream end of the downstream sieve surface 51 because the axis is oriented in the transport direction. The cans C and the bottles B are formed on the upstream sieve surface 41 by cutting a part of the body into a round bar 42.

This is to prevent the sunk body from colliding with the round bar 52 in the middle of the round bar 42 when shifting to. In addition, the upstream ends of the two slightly shortened round bars 52 on both sides of the third round bar 52 from the side wall 14 and the two upstream round bars at positions sandwiching the third round bar 52 The connecting round bar 42T whose downstream end is inclined at a predetermined angle with respect to the transfer direction.
The connecting round bar 42T smoothly moves the oriented cans C and bottles B from the upstream sieve surface 41 to the downstream sieve surface 51 which is horizontally displaced by half a mesh. Work as a guide to transition to.

A flat plate 59 for discharging cans C and bottles B on the sieve is provided with a step 58 downward from the downstream end of the downstream sieve surface 51. In addition, below the upstream sieve surface 41, a slope 4 for sliding down newspapers P and magazines M that are eliminated as under sieve.
Subsequent to 9a, an outlet 49 for newspapers P and magazines M is formed in a vertical direction below the downstream sieve surface 51 from a connection point between the upstream sieve surface 41 and the downstream sieve surface 51. .

Some of the newspapers P and magazines M are caught on the inclined plates 45a or 45b and transported over the upper end surfaces thereof, but the steps 46a or 46b formed on the upper end surfaces are formed. Reaches the step 46a,
Since the position of the upper end surface is different between the upstream side and the downstream side of 46b, the weight balance to both sides is lost,
Due to the relationship of the inclination directions of a and 45b, it slides down to the side wall 14 side and falls from the opening of the round bar 42 of the upstream sieve surface 41.

Further, the newspaper P / magazine M which is caught on the round bar 42 of the upstream sieve surface 41 and transported across the round bar 42
However, since the downstream end of the round bar 42 and the upstream end of the round bar 52 on the downstream sieve surface 51 are displaced in the horizontal direction by half an opening, the round end cannot be transferred to the round bar 52. The rod 42 falls from the downstream end. Part of round bar 42 is connected round bar 42T
Is connected to the round bar 52 by the connecting round bar 42T.
Since it is inclined with respect to the transport direction, the straddling newspapers P and magazines M also lose their weight balance to both sides at this point and slide down. Newspapers P and magazines M as sieves from the upstream sieve surface 41 or the downstream sieve surface 51 are inclined surfaces 4.
The toner drops through the outlet 9a or directly to the discharge port 49, and is conveyed out of the system by a conveyor (not shown).

On the other hand, cans C and bottles B which are transferred from the charging surface 31 to the upstream sieve surface 41 under linear vibration have their axes oriented in the transfer direction and a part of the body is submerged between the round bars 42. To the downstream side, and is transferred to the downstream sieve surface 51 via the connection point. At this connection point, the round bar 42 of the upstream sieve surface 41
And the round bar 52 of the downstream sieve surface 51 are shifted in the horizontal direction by an amount corresponding to a half opening, but the downstream end of the round bar 42 and the round bar 52
Of the cans and bottles B submerged between the round bars 42 so as not to collide with the round bar 52 by being guided by the connecting round bars 42T connecting the upstream ends of the round bars. Sieve surface 4
Since the step 48 is provided between 1 and the downstream sieve surface 51, the transfer of the cans C and the bottles B proceeds smoothly. Then, the cans C and the bottles B are partially transported to the downstream end by sinking a part of the body between the round bars 52 of the downstream sieve surface 51, and are discharged from the downstream end of the on-screen discharge flat plate 59 through the step 58. . As for cans C and bottles B mixed with newspapers P and magazines M to be put into the vibrating sieve 1 for sorting cans and bottles, newspapers P and magazines M are excluded in this way, and cans C and bottles B are Be sorted out.
