DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibrating sorter, and more particularly, to a vibratory sorter for sorting and removing films and sheets from a mixture of films and sheets and glass bottles and metal cans. It concerns the device.

[0002]

2. Description of the Related Art In recent years, glass bottles and metal cans discharged from ordinary households have been separately collected as recyclable recyclable waste, mainly in bags such as plastic films and sheets. In order to recycle glass bottles and metal cans, first of all, a plastic film containing these
A bag such as a sheet is opened by a bag breaking machine to break the bag, and then films and sheets as broken bag pieces that are a hindrance in the sorting and collecting process of glass bottles and metal cans are removed. However, a suitable apparatus for sorting films and sheets from glass bottles and metal cans has not yet been developed, and even the latest sorting plants rely on manual work.

[0003] General refuse discharged from highway service areas, theme parks, transportation facilities, etc. includes not only glass bottles and metal cans but also lunch boxes, paper bags, magazines, newspapers, etc. Glass bottles and metal cans are sorted and collected after the bag is broken, and plastic films, sheets and papers are removed as combustibles.

[0004] As a device for sorting these films and sheets, a device already proposed has been proposed as disclosed in Japanese Utility Model Application Laid-Open No. 61-1 / 1986.
There is “Trommel Screen” according to Japanese Patent No. 87276. In this method, garbage is put into a drum provided with sieves on the peripheral side, and glass dust and vinyl sheets are sorted. Further, in the "waste sorting apparatus" disclosed in Japanese Patent Application Laid-Open No. 4-267977, the waste is supplied on an inclined belt having a large number of holes moving upward, and a suction chamber is provided on the lower surface of the belt at the supply position. Also disclosed is a belt conveyor that applies ultrasonic waves to the belt. That is, a light weight object such as a vinyl sheet is sucked by the belt and moves upward, and a heavy material moves down the belt by its own weight to select the belt conveyor. In addition, a method of scooping up films and sheets with comb teeth, a method of vacuum suction, and a method of air separation can be considered, but these methods are not necessarily preferable methods because the apparatus becomes large or complicated.

(Conventional example) To solve the above problem, the present applicant has filed a "vibration sorter" according to Japanese Patent Application No. 7-158556.
Has proposed a simple vibration sorter for sorting films and sheets from glass bottles and metal cans.

In FIG. 2, it receives a transfer force in the direction indicated by arrow b '.

Referring to FIGS. 11 and 12, the vibration trough 1 'has, in order from the upstream side, a receiving table 4' for unsorted products such as a film / sheet F and a glass bottle / metal can V and a dispersion table 5 '. ', And a sieving section 6'.

That is, the receiving table 4 'is inclined slightly downward toward the downstream side, and an unsorted material from a bag breaking machine (not shown) is supplied. In addition, a dispersing table 5 ′ for expanding the unsorted material input and orienting the axis of the glass bottle / metal can V in the transfer direction through a step D ₁ ′ downward from the downstream end of the receiving table 4 ′ is also the same. It is provided with a slight downward inclination toward the downstream side.

In the sieving section 6 ', FIGS.
Referring to FIGS. 14 and 12, which are partial perspective views of the sieve separating section 6 'and FIG. 15 showing a cross section taken along the line [15]-[15], sieve units 10', 20 ', 30', 4
0 ', 50', 60 'is stepped D ₃ downward respectively' are arranged in cascade in 6 stages to the transport direction through the. The upstream end of the uppermost sieve unit 10 ′ is inserted immediately below the upstream dispersing table 5 ′, and a step D ₂ ′ is formed between the upstream dispersing table 5 ′ and the dispersing table 5 ′.

Each of the sieve units 10 ', 20', ..., 6
0 'is similarly configured, so that the sieve unit 20' will be described. In the sieve unit 20 ', six round rods 21' drop the glass bottle / metal can V with the axis centered in the transport direction. Along with the openings S to be made, the sieve surface is arranged in parallel with a slight downward inclination in the transport direction. The downstream end of the round bar 21 'extends to just above the upstream end of the lower sieve unit 30'. As shown in FIGS. 12 to 15, the cross section of the upstream end of the round bar 21 ′ is cut in a predetermined range from the upstream end to the downstream side so as to receive below the opening S of the six round bars 21 ′. U-shaped, the downstream end section is a semi-circular shape with an upward opening, and five consecutive sieve transfer trucks 22 ′ connected in the width direction with a downward slope toward the upstream side.
Are provided, and both side edges are fixed to the round bar 21 ′ by welding. Then, as shown in FIGS. 12 and 14, the round bars 21 'at both ends are formed on both side walls 2a', 2a of the vibration trough 1 '.
b 'is fixed by welding via mounting plates 23a' and 23b '.

As described above, each sieve unit is constructed in the same manner.
1 ', like the under-sieving truck 32', the lower one digit is denoted by the same reference numeral as the sieve unit 20 '. Then, the downstream end of the under-sieve transfer truck 22 'and the lower-stage sieve separation unit 3
A gap G ₁ ′ for dropping the glass bottle / metal can V is provided between the upper end of the under-sieve transfer truck 32 ′ at 0 ′.

[0015] The downstream end of the vibrating trough 1 'is
Following the 0 'round bar 61', a sieve discharge port 7 'for discharging films and sheets F is formed, and a glass bottle / metal can V is discharged to the downstream end of the bottom surface 3' of the vibrating trough 1 '. An under-sieving outlet 8 'is provided.

The conventional vibration sorting apparatus 100 'is constructed as described above, and its operation will now be described.

Referring to FIGS. 11 to 15, film / sheets F and glass bottle / metal can V sent from a bag breaking machine will be described.
The unsorted material mixed with is the receiving table 4 'in the vibration trough 1'
And deposited in a mountain shape. Since the vibration trough 1 ′ is inclined downward toward the downstream side and is linearly vibrated, the unsorted material is transferred in the direction of the arrow b ′ on the downstream side while being collapsed,
Step D ₁ 'dropped the loosened notwithstanding et distributed base 5' moves to.

In the dispersing table 5 ', the unsorted material is spread to the full width, and the glass bottle / metal can V is oriented so that the axis is directed in the transport direction, and the step D at the downstream end is formed.
₂ 'is dropped and moved to the sieve unit 10' in the sieve separating section 6 '. At this time, by dropping the step D ₂ ′, the unsorted material increases the ratio of the heavy glass bottle / metal can V being lower than the film / sheets F, and is sieved by the round bar 11 ′ of the sieving unit 10 ′. To the surface.

Referring to FIG. 15, a film or sheet F having a large area as a piece of bag is transported downstream on the sieve surface so as to straddle between round bars 11 '. the film·
Even if there is a portion that hangs down into the opening S accompanying the glass bottle / metal can V on the sheets F, the film / sheets F do not slip downward because they are received by the under-sieve transfer truck 12 '. .

On the other hand, the oriented glass bottle / metal can V
Drops the mesh S between the round bars 11 'as it is, and the glass bottle / metal can V with insufficient orientation also falls from the bottom or neck into the mesh S and is received in the under-sieving transfer truck 12'. The glass bottle / metal can V moves along the downward inclination toward the upstream side of the below-sieve transfer truck 12 ′ in a direction opposite to the entire transfer direction in the vibrating trough 1 ′, and the upstream end of the below-sieve transfer truck 12 ′. From the part onto the bottom surface 3 '.

The films / sheets F which have passed through the sieve unit 10 'are transferred to the sieve unit 20' as they are,
It is transported on the sieve surface formed in 1 '. Further, in the sieve unit 10 ', for example, a glass bottle / metal can V which is on the film / sheets F and has not been sufficiently oriented in the axial direction, the sieve unit 10' is connected to the film / sheets F.
To the sieve unit 20 ′, but the sieve unit 1
When falling down the step D ₃ ′ between 0 ′ and the sieve unit 20 ′, the same sort as in the sieve unit 10 ′ is performed by producing a material separated from the films and sheets F.

Then, such sorting is performed by the sieve unit 3.
Repeated at 0 ′,..., 60 ′, the film / sheets F are discharged from the sieve discharge port 7 ′ at the downstream end, and the glass bottle / metal can V is transferred to the downstream side on the bottom surface 3 ′. It is discharged from a downstream sieve discharge port 8 'at the downstream end. As described above, the films / sheets F are sorted and removed, and the glass bottles / metal cans V as valuables are further sorted and sent to a recycling factory.

That is, the conventional vibration sorting apparatus 100 '
In the above, as described above, the under-sieve transfer truck 12 ′
Is inclined downward toward the upstream side in a direction opposite to that of the vibrating trough 1 ′, so that the weight is larger than that of the films and sheets F, and the transfer force in the direction of the arrow b ′ is received by the linear vibration. The glass bottle / metal can V having a large momentum is also transferred to the upstream side of the sieved transfer truck 12 'in a direction opposite to the transfer direction and surely falls to the bottom surface 3'. That is, the gap G glass bottles, metal cans V from undersize transfer track 12 _1
It jumps over ₁ 'and is transferred to the lower sieve transfer truck 22' in the lower sieve unit 20 '. Such transfer continues to the downstream end, and mixes with the film / sheets F at the downstream end to reduce the sorting accuracy. It is possible to avoid the trouble of letting them go.

[0024]

As described above, a variety of miscellaneous materials, such as broken films / sheets F, glass bottles / metal cans V, are put into the conventional vibration sorter 100 '. Films and sheets F therein are transported on a round bar and discharged as a sieve.
Then, for example, step D ₃ between the 'round bars 21' of the sieve unit 20 and 'round bars 31' sieving unit 30 Film
It is useful for separating the sheets F from the glass bottle / metal can V. However, the actual at the time of operation, the upstream side of the round bar 21 'and the downstream side of the round bar 31' and the newspapers, magazines or wound hanging the film sheets F in step D ₃ of, as shown in FIG. 15 M may be caught and stagnant, and subsequent transport of unsorted objects may be obstructed, causing overflow on the round bar. In such a situation, the entire municipal solid waste sorting plant must be stopped to manually clear the transport clogging, and the municipal solid waste disposal capacity is greatly reduced.

Therefore, the present invention can stably sort glass bottles, metal cans V, etc. under a sieve without stagnation of films / sheets F, newspapers, magazines M, etc. on a round bar. An object of the present invention is to provide a vibration sorting device that can be reliably performed.

[0026]

According to the vibration sorter of the present invention, a plurality of long grizzly bars are arranged between both side walls of a vibrating trough in parallel with a certain opening toward a downstream side to form a sieve surface.
Immediately below each opening, a plurality of gutter-shaped undersize transfer troughs of a predetermined length are provided at substantially equal pitches from the upstream side to the downstream side, and the upstream-side undersize transfer trough and immediately A gap where the sieve falls is provided between the downstream sieve transfer trough and the downstream sieve transfer trough.

Therefore, the films / sheets F, newspapers / magazines M, etc. as sieves are transported on the long grizzly river without stagnation and clogging does not occur. Sorting with the like progresses stably and efficiently.
