Used in the separation process for recyclable waste)
The present invention relates to a bag removing apparatus for collecting thin film bags such as garbage collection bags from these resources.

[0002]

2. Description of the Related Art In recent years, the environment surrounding waste has changed,
It is an important issue to collect empty cans and empty bottles as valuables from garbage discharged from homes and the like, and to use them as resources. Opening the garbage collection bag, etc., and sorting and collecting recyclable garbage from waste in which empty bottles, empty cans, etc. are mixed, film-like waste mixed with this mixed waste becomes valuable resources. An obstacle to sorting. Conventionally, this removal work has been performed manually, but there is a problem in terms of safety and health, and in order to solve such a problem, a technique of separating film-like waste from mixed waste has been developed.

When the mixed waste is put into the inclined plate or the inclined sorting means, the glass bottle among the solid trash C ₁ collides with the glass bottles or other solid garbage, breaks or collides with the inclined plate or the like. There is a drawback that the glass bottle is broken and the recovery rate of the valuable glass bottle is significantly reduced. Therefore, the use of this sorter in the bag removal process performed as a pre-process of the mixed waste separation process performed for the recycling of the mixed waste reduces the recovery rate of valuable resources. Therefore, it is not preferable.

In the bag removing apparatus shown in FIG. 17, fluff-like dust is put into a porous drum simultaneously with solid dust,
When the fluff-like dust is turned overlapping, it overlaps the waste and the previously aspirated a fluff-like dust of the solid, the suction force of the air intake chambers ₈₁ is inhibited, sufficient attraction force Is often not obtained, and therefore, there is a disadvantage that the recovery rate of fluffy refuse decreases. Additionally, string-shaped fluff-like dust entangled porous drum, is inhibited suction force of the air intake chambers 8 _1, may not sufficient suction force can be obtained, fluff-like recovery of dust There is a disadvantage that it decreases.

Next, another embodiment of the bag removing apparatus according to the present invention will be described with reference to FIG. In FIG.
The same parts as those of the bag removing device are denoted by the same reference numerals, and the description of the same parts will be omitted. In the figure, a drum-shaped rotating body 21 has a hole or an opening 2 formed in a rotating plate 22 on its outer peripheral wall.
2b are provided in large numbers. As in the above embodiment, the projecting member 23 protrudes from the opening 22b in the outer peripheral direction. The shape of the opening 22b is a shape corresponding to the cross-sectional shape of the projection member 23, and the projection member 23 is not in contact with the turning plate 22, and is not in contact when the turning plate 22 is turned and opened. And Since the protruding member 23 has a rectangular column shape, the opening 22b has a rectangular shape. If the projection member 23 is cylindrical, the cross section is circular, so that the shape of the hole or opening 22b is elliptical.

Next, another embodiment of the bag removing apparatus of the present invention will be described with reference to FIGS. In the present embodiment, a bag removing apparatus that can obtain a uniform removal effect even when there is a difference in the collection of fluffy refuse according to the mixing ratio of the mixed waste and the characteristics of the refuse will be described. In the embodiment of FIG. 5, a pressing means 28 for the mixed waste is provided above the drum-shaped rotating body 21. The pressing means 28
The pressing plate 29 is rotatably provided on the supporting member 30, and the pressing plate 29 and the supporting member 30 are regulated by contracting means 31 such as a spring. As shown in FIG. 5 (a), the mixed waste C from the charging chute 26 is injected just above the drum-shaped rotator 21, and the drum-shaped rotator 21 is rotating. Is conveyed while pressing the pressing plate 29. Then, as shown in FIG. 5B, the solid dust C ₁ is pushed off the pressing plate 29 to remove the drum-shaped rotating body 2.
The fluff-like dust C ₂ discharged to the front of 1 is caught by the projection member 23 and conveyed downward.

In the embodiment shown in FIG. 6, the mixed waste C
Is provided with a waste input duct 32 also serving as a chute for inputting the mixed waste C. An input port 33 is provided in the waste input duct 32, and a movable plate 34 is provided at a distal end thereof. The movable plate 34 is formed of rubber or the like, and can easily move when the solid debris C ₂ abuts thereon, and can collect the solid debris C ₂ forward. A gap 35 is provided between the adjacent movable plates 34, and the projection member 23
Is configured to be easily passed.

The waste input duct 32 is arranged such that its input port is located above the drum-shaped rotating body 21. The mixed waste C is supplied to the input port 3 of the waste input duct 32.
3, the solid dust C ₂ is thrown into the upper part of the drum-shaped rotating body 21, the solid dust C ₂ is discharged by pushing the movable plate 34 provided at the tip of the waste throw-in duct 32, and the fluff-shaped dust C ₂ is

As means for pressing the mixed waste C other than those described above, a blower is installed near the drum-shaped rotating body, and air is blown from the blower to the vicinity where the mixed waste is charged, although not shown. Thus, fluff-like dust may be surely caught on the protruding member.

The rotating plate is configured to be opened by its own weight, and needs to have a weight that can be opened by its own weight. However, to rotate the drum-shaped rotating body at a relatively high speed,
It is necessary to avoid the wind pressure when the rotating plate is opened, and it is possible to avoid the wind pressure by providing the rotating plate with a grid or a net.

On the other hand, when the rotating plate is opened and closed only by its own weight, it swings largely around the rotating shaft at the lower part of the rotating drum. When the drum-shaped rotating body is rotated at a high speed, the swinging amplitude of the rotating plate becomes too large, and there is a possibility that the rotating plate may collide with the adjacent rotating plate or generate a metallic sound. In this case, it is very effective to attach the guide rail over the entire circumference of the rotating drum as shown in FIG.

Referring to FIG. 8, another embodiment of the present invention will be described. In FIG. 8, the guide rail 25 is composed of an upper guide rail 25a and a lower guide rail 25b.

Upper guide rail 2
5 a is arranged along the outer circumference of both ends of the drum-shaped rotating body 21, and the lower guide rail 25 b gradually increases the distance from the surface of the drum-shaped rotating body 21 as it goes below the drum-shaped rotating body 21. It is arranged to become.
The rotating plate 22 is rotatably supported by the rotating shaft 24, and a guide roller 38 is provided on the opposite side. As the drum-shaped rotating body 21 rotates, the guide roller 38
Moving along the guide rail 25, the rotating plate 22 operates to open around the rotating shaft 24 as described above by its own weight. When the rotation plate 22 starts to open, the rotation shaft 24
Since the opposite end is supported by the guide rail 25b, it is gradually opened at an angle corresponding to the distance between the guide rail 25 and the drum-shaped rotating body 21 without sudden release. For this reason, when the drum-shaped rotating body 21 is rotated at a high speed, the rotating member 22 operates so as to be smaller than the rotating radius of the rotating plate 22, so that the protrusion member 23 is pulled out from the opening provided in the rotating plate 22. The lower guide rail 25b is provided so that the distance from the drum-shaped rotating body 21 is sufficiently maintained so that the fluff-like dust is reliably collected.

Since the guide rail 25 and the sliding portion 37 of the rotary plate 22 slide with the drum-shaped rotating body 21, an appropriate lubricant may be used as a measure against wear. Further, as shown in FIG. 10, a groove-shaped guide rail 36 having a groove 36a may be attached. In that case, FIG.
The behavior as shown in FIG.
6a is engaged with the sliding portion 37 of the rotating plate 22,
Is regulated by the groove-shaped guide rail 36. In FIG. 11, a guide roller 38 is provided on the sliding portion 37 of the rotating plate 22, and is completely regulated by the trajectory of the guide roller 38 regardless of the direction of movement of the rotating plate 22.

The position of the rotating plate 22 supported by the guide roller 32 is at the end opposite to the rotating shaft 24 in the above-described embodiment. Axis 2
Since it has a function of generating a moment around 4, a sliding portion for causing the movement of the rotating plate 22 to follow the guide rail 36 as shown in FIGS. 37 has various forms, but these are
Opening and closing are regulated by guide rails.

For example, in FIG. 12A, a sliding portion 37 is provided at the center of both ends of the rotating plate 22 provided on the rotating shaft 24, and the sliding portion 37 follows the guide rails 25 and 36. Have been. In FIG. 12B, sliding portions 37 are provided at the center of both ends of the rotating plate 22 provided on the rotating shaft 24, and the sliding portions 37 are provided at both ends of the rotating plate 22. Is provided as a support shaft. In the guide rails 25 and 36, the upper half of the drum-shaped rotating body 21 provides a track in the tangential direction of the drum-shaped rotating body 21, and the lower half of the drum-shaped rotating body 21 has a radius of curvature greater than the radius of the drum-shaped rotating body 21. By reducing the size and releasing the rotating plate 22, the fluff-like dust can be pulled out from the protruding member. In FIG. 12C, the rotating plate 2
Sliding portions 37 are provided on both ends of the drum-shaped rotating body 21 from the rotating shaft 24 provided on the rotary shaft 2 using the principle of leverage with the rotating shaft 24 as a fulcrum, and guide rails 25 and 36 are provided.
The turning plate 22 can be opened and closed by making the radius of curvature of the drum-shaped rotating body 21 smaller at the upper part and equal to the radius of curvature of the drum-shaped rotating body 21 at the lower part.

FIG. 13 shows an embodiment which can be added to the above-described embodiment to prevent an abnormal excessive load on the rotating plate and improve the bag removing rate. In order to allow the projecting member 23 attached to the drum-shaped rotating body 21 to pass through the outside of the drum-shaped rotating body 21 of the bag removing device,
And an embodiment in which a fixed outer shell 39 is provided. In the present embodiment, as shown in FIG. 14, the dust put on the outer shell 39 and the drum-shaped rotating body 21
Since it has a relative speed, the fluff-like dust is easily caught on the projection member 23, and the bag removing performance is improved. Further, as shown in FIG. 15, by using the outer shell 39 and the pressing mechanism (the pressing means 28) described in FIG. 5 together, it is possible to further improve the bag removing rate.

[0036]

As described above, the bag removing apparatus of the present invention is formed with a relatively simple structure of the projection member and the drum-shaped rotating body, and is a valuable resource (resource garbage) due to breakage of empty glass bottles. This has the advantage that solid waste and thin film-like waste such as garbage collection bags can be reliably separated and collected.

Further, the bag removing device of the present invention has a structure in which the rotating plate is rotated by its own weight and is opened, so that when the rotating plate is rotated, fluff-like dust caught on the projection member is removed. There is an advantage that the pull-out can be reliably performed, and the power plate does not need to be rotated by power, so that the power cost can be reduced.

Further, the bag removing apparatus of the present invention can push the mixed waste to the drum-shaped rotating body by guiding the mixed waste to the position directly above the drum-shaped rotating body, thereby reliably removing the fluff-like dust. There are advantages that can be done.

Further, in the bag removing apparatus of the present invention, the outer shell portion covers the drum-shaped rotating body from the charging chute into which the dust is input, and the projection member protrudes from the outer shell portion. Due to the difference in the relative speed with the rotating body, fluff-like trash can be reliably caught and collected,
By improving the bag removal rate and providing an outer shell at the garbage input section, mixed waste can be received at the outer shell and fluffy garbage can be collected, so the strength of the rotating plate can be compared. There is an advantage that the durability of the drum-shaped rotating body can be enhanced even if the target is suppressed.

Further, in the bag removing apparatus of the present invention, the rotating plate for hooking the fluff-like garbage in the mixed waste with the protruding member and pulling it out of the protruding member is regulated by the guide rail. Even when the drum-shaped rotating body is rotated at a high speed, there is no contact between adjacent rotating plates, so that there is an advantage that a disturbing metal sound is not generated and the bag removing rate can be increased.
