Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus used for selecting and collecting empty cans made of aluminum or iron from dust collected from stations such as JR stations and various play facilities. More specifically, the present invention relates to an apparatus suitable for sorting and collecting empty cans from dust collected in a bag. Furthermore, the present invention relates to a bag breaking device and a wet dust collecting device suitable for use in such a device.

[0002]

2. Description of the Related Art In recent years, from the viewpoint of resource reuse, methods have been proposed for recovering and reusing renewable substances from various wastes. Typical examples of reusable substances are beverage cans such as juice and beer. A large amount of waste including such empty cans is collected from dust boxes such as platforms at JR stations or various play facilities.

In addition to empty cans to be collected, such wastes include glass bottles, magazines, newspapers, tissue paper, lunch boxes, and the like. Therefore, it is necessary to efficiently separate these and take out only empty cans.

Further, such wastes are often collected in a plastic bag. For this reason, when disposing of the bagged waste, it is necessary to first break the bag. As the bag breaking device, a pair of rollers with cutting blades are intermittently rotated in reverse while being hydraulically approached,
It is known that the bag is torn through the bagging waste between them. Further, there is known a structure in which a conveyor belt is configured so as to have a U-shaped cross section, a cutting blade is attached to the surface of the conveyor belt, and the bagging waste is conveyed on the cutting blade to break the bag. There is. Alternatively, there is known one in which a cutting blade or a heat source is installed at a fixed position above the conveyor belt, and the bag is ruptured by passing bagging waste through this.

[0005]

However, conventionally, there has not been proposed an apparatus for efficiently and automatically separating empty cans from such wastes without resorting to manual work.

Further, in the above-mentioned various types of bag breaking devices in the related art, the bag after being broken is often caught by the cutting blade or other portions. The hooked bag needs to be removed manually, which is inefficient. In addition, since there are various sizes of bagging waste, there is also a drawback that large bagging waste is clogged in the apparatus.

Further, the waste generally contains wet dust such as tissue paper containing water. Such wet paper adheres to various parts of the waste treatment equipment,
There is a high risk that it will get stuck there. However, conventionally, no method has been proposed for efficiently collecting wet dust without resorting to manual work.

An object of the present invention is to propose a device for efficiently and automatically selecting and collecting empty cans made of aluminum and iron from bagged wastes collected from JR stations and the like.

Another object of the present invention is to propose a bag breaking device capable of efficiently carrying out a bag breaking operation for bagging waste.

Further, an object of the present invention is to propose a wet dust collecting apparatus capable of efficiently selecting and collecting wet papers from waste.

[0011]

In order to solve the above-mentioned problems, in the present invention, the collected bagging waste is broken by a bag breaking device and the waste inside is sorted by wind sorting. At the same time, the wind-sorted waste is further separated using a trommel screen that is used to classify ores etc. by particle size so that only empty cans made of aluminum and iron are collected. ing. It is preferable that the waste dust after passing through the bag breaking device is passed through a wet dust collecting device to collect the wet dust prior to the wind sorting.

As means for performing the wind power selection of the present invention, by forming an air flow that is directed substantially obliquely upward, the transported waste is wind-selected, and the light weight first waste is directed upward. A structure that blows up toward the top, drops the second waste such as a heavy glass bottle, and blows off the third waste mainly containing aluminum and iron empty cans in a substantially horizontal direction. Can be adopted. According to this configuration, light waste (first waste) such as newspapers, tissue paper, and paper bags is generated by the formed air flow.
Is blown up. However, heavy waste (second waste) such as glass bottles and thick magazines falls without being blown by the air flow. Therefore, only the second waste containing mainly empty cans made of aluminum and iron is supplied to the trommel screen.

Here, in order to collect the first waste that has been blown up, a belt conveyor provided with a mesh belt may be used. That is, the mesh belt is arranged so that the first waste blown up on the surface of the mesh belt sticks by the wind force. Then, if the waste attached to this area is conveyed to the outside of the air flow range, the waste attached to the surface of the mesh belt will fall due to its own weight. In this way, lightweight waste is sorted and collected.

Next, in the trommel screen, a large number of openings having a size and shape through which empty cans can pass are formed on the outer peripheral surface on the outlet side, and the empty cans are separately collected through these openings. To be done. However, some thick magazines and lunch boxes have sizes and shapes that pass through such openings. To prevent such waste from passing through the openings together with the empty cans, place them at a position slightly larger than the diameter of the empty cans on the outside of these openings in the radial direction. It is preferable to arrange the baffle plate so as to cover these openings. In this way, these magazines and lunch boxes once pass through the opening, but the baffle prevents the magazines and lunch boxes from passing through the opening together with the empty cans.
Therefore, only empty cans are sorted and collected.

The empty cans made of aluminum and iron, which are separately collected by the Trommel screen, are flatly crushed by a flattener and then classified into aluminum and iron by a sorter.
Then, it is pressed by a press into a mass having a certain shape and size.

Next, as the bag breaking device, a bag-filling body charging port formed at the upper end, and a pair of belt conveyors which are arranged so as to face each other so that the interval gradually narrows downward from the charging port, and these. Between a plurality of bag-breaking blades attached to the respective conveyor belts that make up each of the conveyor belts, a discharge port formed at the lower end between these conveyor belts, and a conveyor belt near the discharge port. In the center position of the shaft, a shaft member rotatably arranged in the width direction of these conveyor belts and a drive device for driving the conveyor belt from the discharge port toward the insertion port side are provided. The thing of a structure can be adopted.

In the bag-breaking device of this structure, when the bagging waste is loaded from the loading port at the upper end, it drops between the belt conveyors. Since the shaft member is arranged on the lower end side between the belt conveyors, the bag is in a state of straddling over this, and in this state, the cut on the conveyor belt moving upward from both sides. Rubbed by the blade. As a result, the bag straddling the shaft member is swayed while being swayed to the left and right, and the waste contained therein falls down through the rupture opening.
The torn bag that is in a state of straddling the shaft member also falls down together with the waste due to the rotation of the shaft member. Therefore, there is no problem that the torn bag is caught by the cutting blade and conveyed upward.

As the bag breaking device, the following structure can be adopted in addition to the above structure. That is,
Within the bag-filling body drop passage formed between the inlet of the bag-filled body on the upper end side and the outlet of the lower-end side, the rotary body with a plurality of cutting blades for bag breaking is formed horizontally on the outer periphery. Placed in
A side wall plate having a plurality of cutting blades for bag breakage formed on the surface thereof is vertically arranged at a predetermined interval with respect to the rotating body. The side wall plate is supported so as to be rotatable around the lower end so as to approach and leave the rotating body, and the back surface of the side wall plate is supported by the elastically deformable member.

In this bag breaking apparatus, the bagging waste falling from the charging port is dropped while being cut between the rotating body and the side wall plate by the cutting blade formed on the rotating body and the side wall plate. The side wall plate is supported by an elastically deformable member, and is rotatable around its lower end. Therefore, even if a large bagging waste is thrown in, the side wall plate can be retracted in the direction away from the rotating body, so that the bagging waste is not clogged between them.

As the bag breaking device, the former bag breaking device may be connected to the lower side of the latter bag breaking device.

On the other hand, the wet dust collecting apparatus according to the present invention is
It is equipped with a belt conveyor arranged diagonally.By dropping the waste containing wet dust on the transport surface on the lower end side of this belt conveyor, the wet dust adhering to the transport surface is transported upward. , It collects wet dust. With such a simple configuration, it is possible to reliably collect the wet dust that is an obstacle in the post-treatment.

[0022]

Embodiments of the present invention will be described below with reference to the drawings.

Overall Structure FIGS. 1 and 2 show the line structure of a sorting and collecting apparatus to which the present invention is applied. In these figures, 1 is
A hopper for inputting the collected bagging waste W. In the bagging waste W, magazines, lunch boxes, newspapers, tissue paper, etc. are mixed together with empty cans made of aluminum and iron. In addition, newspapers, tissue paper, and the like also include those that are wet and contain water. The bagging waste W put in the hopper 1 is supplied to the first belt conveyor 2. The bagged waste W is conveyed diagonally upward by the first belt conveyor 2 and discharged from the upper end.

Below the discharge end of the first belt conveyor 2, an upper end input port 15a of the primary bag breaking machine 15 is opened. The primary bag breaking machine 15 breaks a large bag of bagging waste. The small bagging waste drops in the primary bag breaking machine 15 as it is. Below the primary bag breaking machine 15, a secondary bag breaking machine 16 is connected. Primary bag breaking machine 1
The waste whose bag is broken in 5 and the small bagging waste which has passed without being broken are at the bottom end discharge port 15b.
From the secondary bag breaking machine 16 to the upper end input port 16a.
In the secondary bag-breaking machine 16, the bag of waste that has fallen in the bag-filled state is broken. The waste that has dropped from the side of the primary bag breaking machine 15, and the bag and the waste contained therein that have been broken here are discharged through the discharge port 16b at the lower end,
It falls into the hopper 17 arranged below it.

The inclined bottom surface on one side of the hopper 17 is defined by the conveying surface of the wet dust collecting device 18, and the waste material drops from the secondary bag breaking machine 16 there. The wet dust collecting device 18 sorts and collects wet papers from the dropped wastes. Wastes other than the wet papers are dropped on the conveying surface of the wet dust collecting device 18 by its own weight, and are supplied to the second belt conveyor 19 arranged obliquely. The waste is conveyed to the discharge end on the upper end side by the second belt conveyor 19.

Below the discharge end of the second belt conveyor 19, a blower 3 constituting wind force selecting means is installed. Air blowout port 3a of this blower 3
Is directed obliquely upward from the lower side of the discharge end of the belt conveyor 19. That is, it faces the entrance center of the trommel screen 4 described later. Therefore, the air flow blown from here flows obliquely upward as indicated by arrow A. In this example, the air volume and the air velocity of the air flow are set so that the empty cans made of aluminum and iron can be conveyed in a substantially horizontal direction against gravity.

Therefore, among the waste materials W discharged toward this air flow, empty cans made of aluminum or iron are carried in the horizontal direction and supplied to the Trommel screen 4 having an opening at an adjacent position. To be done. Wastes other than empty cans are discharged as follows according to their weight, shape, discharge state from the belt conveyor 19, and the like. First, a heavy glass empty bottle or the like (second waste) W2 falls by gravity without riding on the air flow. Light-weight and large-sized pressure-sensitive area such as tissue paper, newspaper, or fine dust (first waste) W1 is blown upward by the airflow A. Here, even wastes other than aluminum and iron empty cans are also transported to the Trommel screen 4 side together with empty cans due to their shapes and the like. Therefore, the waste (third waste) W3 containing empty cans mainly made of aluminum and iron is used for the trommel screen 4.
Will be supplied.

Here, the lightweight first waste W1 blown up obliquely upward by the air flow A is directed to a predetermined place by the mesh conveyor 5 arranged above the inlet 41 of the trommel screen 4. It is transported and collected. The mesh screen 5 will be described later.

The trommel screen 4 is a cylindrical sieve and is installed on the pedestal 6 so that its outlet side 42 is slightly lower than its inlet side 41. On the outer peripheral surface of the trommel screen 4, a mesh-shaped fine mesh portion 43, a 30 mm square sieve mesh portion 44, and empty cans can pass from the inlet 41 side toward the outlet 42 side. A sieve mesh portion 45 formed of rectangular openings having various sizes and shapes is formed. The waste W3 put into the trommel screen 4 is conveyed toward the outlet 42 side as it rotates. Fine iron scraps and the like fall from the mesh-like fine sieve mesh portion 43, and are eliminated through the sorting chute 401 arranged therebelow. Further, tabs of empty cans, lids of bottles, and the like fall from the intermediate sieve-mesh portion 44, and are eliminated through the sorting chute 402 arranged therebelow. The empty cans made of aluminum or iron fall from the largest sieve mesh portion 45 and are discharged through the sorting chute 403. Wastes larger than this, such as magazines and lunch boxes, are discharged from the outlet 42 of the trommel screen 4, received by the chute 7 installed there, and discharged in the lateral direction. The structure of the largest sieve mesh portion 45 of the trommel screen 4 will be described later.

Screen mesh portion 4 of the trommel screen 4
The belt conveyer 8 is arranged continuously to the lower chute 403 of FIG. Empty cans are supplied to the lower end side of the belt conveyor 8 via a chute 403. The belt conveyor 8 conveys empty cans toward the flattener 9. Flatner 9
At, the empty cans that have been transported are crushed into a flat shape. Since this flattener 9 is a commonly used one, a detailed description thereof is omitted in this specification.

The empty cans crushed by the flattener 9 are separated by a sorter 11 into aluminum ones and iron ones. This sorter 11 also employs a commonly used one, and therefore detailed description thereof is omitted in this specification.

The empty cans made of aluminum sorted by the sorter 11 are supplied to the can condenser 12, and the empty cans made of iron are supplied to the can condenser 13. In these can densers, empty cans are pressed into a lump having a predetermined shape and size. Usually, it is pressed into a rectangular parallelepiped block. Since such a can capacitor is also commonly used, its detailed description is omitted in this specification.

Through the above steps, from the bagged waste W,
Only empty cans made of aluminum and iron are sorted and collected.

[0034] With reference to diagram 3, 4, 5 of the primary breakage apparatus, the structure of primary breakage device. The primary bag breaking device 15 has a rectangular housing 151 having a structure in which a steel frame is assembled into a rectangular parallelepiped shape and an iron plate is attached to the inside thereof, and the upper end thereof serves as an inlet 15a.
The lower end thereof is the discharge port 15b. Housing 15
A rotary shaft 153 with a cutting blade is horizontally arranged at a position on the upper side in the drop passage 152 in the apparatus 1, and a side wall plate 154 with a cutting blade is arranged so as to face the rotary shaft 153.

As shown in FIG. 4, the rotary shaft 153 comprises a cylindrical rotary shaft main body 153a and a plurality of cutting blades 153b integrally formed on the outer peripheral surface thereof. The rotary shaft main body 153a has the housing 15 at both end positions.
It is rotatably supported on both side walls. As can be seen from the drawing, the cutting blades 153b are formed in four rows in the axial direction at intervals of 90 degrees, and are arranged in a zigzag state with respect to the cutting blades in the adjacent rows.

On the other hand, as shown in FIG. 5, also on the surface of the side wall plate 154, two cutting blades 154a having substantially the same shape are formed in upper and lower rows, and the cutting blades are in a zigzag state between each row. Are arranged as follows. Here, the side wall plate 1
A large number of coil springs 154c are attached to the back surface 154b of 54, and the side wall plate 154 is attached to the side wall of the housing 151 via these coil springs 154c. In addition, the lower end of the side wall plate 154 has the housing 1
It is supported by a support shaft 155 spanned by 51 so as to be rotatable around this. Thus, the side wall plate 154 is
The lower surface is supported so as to be rotatable about its lower end, and the back surface side is attached to the housing side surface via a coil spring 154c. Therefore, when the side plate wall 154 is pushed from the surface side with a force exceeding the spring force of the coil spring, the side plate wall 154 can be swung to the side surface of the housing with the lower end as the center.

The rotary shaft 153 with a cutting blade is adapted to be rotated in a direction indicated by an arrow in FIG. 3 by a driving means such as a motor (not shown).

Structure of Secondary Bag Crushing Machine FIG. 6 and FIG. 7 show a secondary bag breaking machine 16. Figure 6
As shown in FIG. 2, the secondary bag-breaking machine 16 also has a rectangular parallelepiped housing 161 formed of a steel frame, inside which two iron plates 162, 16 are constricted toward the lower side.
3 is mounted in a tilted state. These inclined iron plates 1
On the 62 and 163, belt conveyors 164 and 165 are arranged so as to be inclined along the above. In this example, each belt conveyor is composed of two sets of belt conveyors arranged in parallel. On the upper side of these belt conveyors 164, 165, there is an input port 16a for receiving bagging waste, and the lower ends thereof are at the discharge port 1
6b.

The conveyor belts of these belt conveyors 164 and 165 are chain belts, and cutting blades 166 are attached to the chain belts as shown in FIGS. 6 and 7.

On the other hand, a shaft 167 is arranged horizontally in the same direction as the belt conveyors 164, 165 in the lower direction. The shaft 167 is rotatably mounted between the side walls of the housing 161. The motor 168, which is the drive source of these belt conveyors 164 and 165, is attached to the steel frame pedestal on the back side of each inclined plate 162 and 163, as shown in FIGS. 6 and 7B.

Bag- breaking operation In this example, the bagging waste W is conveyed by the first belt conveyor 2 and is first charged into it from the charging port 15a of the primary bag-breaking machine 15. In the primary bag breaking machine 15, the rotary shaft 153 with a cutting blade is rotated by the motor. While falling between the rotary shaft 153 with a cutting blade and the side wall plate 154 with a cutting blade, the bag of bagging waste is broken. The ruptured bag and the waste inside are discharged from the outlet 15.
It is dropped from b through the secondary bag breaking machine 16 and onto the wet dust collecting device 18.

When a large-sized bagging waste is thrown in here, it may be clogged between the rotary shaft 153 with a cutting blade and the side wall plate 154 with a cutting blade.
However, in this example, the back surface of the side wall plate 154 is the coil spring 1
Since it is supported on the side of the housing through 54c,
The coil spring 15 is provided by the bag that is inserted between the rotating shaft and the side wall plate.
4c is compressed, and the side wall plate 154 retracts in the direction away from the rotating shaft 153. Therefore, it is possible to prevent the bagging waste from being jammed between them and interrupting the bag breaking operation.

Next, the bag breaking operation in the secondary bag breaking machine 16 will be described. The bagging waste that has been directly input from the input port 16a via the primary bag breaking machine 15 falls between the pair of belt conveyors 164 and 165 and rides on the shaft 167 arranged horizontally on the lower side. Thus the shaft 167
Since the chain belts of the belt conveyors on both sides are moved upward by the motor 168 after being in a state of straddling above, the cutting blade 166 formed there is formed.
Rubbed from both sides by. As a result, since the shaft 167 is rotatably supported, the bag in a state of straddling the shaft 167 is swayed while swinging to the left and right, and the waste contained therein drops downward from the rupture opening. A torn bag that straddles the shaft 167 also falls down together with the waste due to the rotation of the shaft 167. Therefore, there is no problem that the torn bag is caught by the cutting blade and conveyed upward.

In this way, the bagging waste is broken, and both the waste inside and the broken bag drop from the discharge port 16b at the lower end toward the wet dust collecting device 18.

Structure of Wet Dust Collecting Device Next, as shown in FIGS. 1 and 8, the wet dust collecting device 18 of this embodiment comprises a belt conveyor 181. This belt conveyor 181 is arranged in an inclined manner,
It is driven by a motor 182 so as to convey the waste that has dropped to the lower end side upward. Motor 182
Drive shaft 183 connected to the driven shaft 1 and the driven shaft 1 located on the upper side
A plurality of chain belts 185 are bridged between 84, and projections 186 are formed on the surfaces of these chain belts 182 at equal intervals.

Among the wastes dropped from the secondary bag breaking device 16 onto the belt conveyor 181, wet papers adhere to the chain belt 185 and are conveyed upward.
On the other hand, waste such as empty cans is rolled down on the surface of the chain belt 185 that is inclined and arranged by its own weight, and is supplied to the second belt conveyor 19 side. Paper attached to the surface of the chain belt 185 is scraped off by a write-down plate 187 arranged at the upper end, or peeled from the belt surface by its own weight and collected in a collecting unit 188 arranged on the back side of the belt conveyor. .

Here, the distance between the chain belts 185 is
Of the wastes dropped from the secondary bag breakage 16, the wastes of a size that can pass through this are set to a size that does not allow empty cans to pass, and the wastes that pass through these spaces are placed below it. It falls on the recovery conveyor 21 that is being used. These wastes are carried out of the line by the recovery conveyor 21.

In this way, wet dust such as wet paper is collected from the waste. The waste from which the wet dust has been removed is conveyed upward by the belt conveyor 19 toward the entrance side of the trommel screen 4.

Structure of Mesh Conveyor Next, the structure of the mesh conveyor 5 will be described with reference to FIG. The mesh conveyor 5 is provided with a mesh belt 51, and chains 52 and 53 are attached to both ends of the belt 51. Chains 52, 5
3 is bridged between the drive side and the driven side sprockets 54, 55. The mesh belt 51 is installed in a state of being inclined downward so that the waste W1 blown up by the blower 3 sticks to it, and moves in the horizontal direction. Also, this belt 5
The conveying path 1 extends to the outside of the area where the air flow A is blown. Therefore, the waste W1 attached to the surface of the mesh belt 51 by the air flow A is conveyed while being attached to the surface while the air flow is blowing, but after reaching the outside of the area. Fall from the belt surface. Therefore, if a recovery pan or the like is installed below, the dropped waste W1 can be recovered.

Structure of Trommel Screen FIG. 10 shows the structure of the trommel screen 4 described above. As shown in this figure, on the outer periphery of the trommel screen 4, from the inlet 41 side toward the outlet 42 side, a mesh-shaped sieve mesh portion 43, approximately 30 m
An m-square sieve mesh portion 44 and an opening sieve mesh portion 45 having an opening and shape that allows empty cans to pass through are formed. Here, in the sieve mesh portion 45 through which empty cans can pass, a baffle plate 47 is attached to the outer peripheral side of the opening 46 at a position slightly spaced from the diameter of the empty cans. Therefore, the empty cans pass through the opening 46, are discharged to the outside thereof, and can further fall down through the space between the opening 46 and the baffle plate 47. However, for example, thick magazines, lunch boxes, and the like, even if they pass through the opening 46, are prevented from falling by the baffle plate 47. Therefore, without passing through the opening 46,
It is conveyed to the side of the outlet 42 of the trommel screen 4, and is discharged to the chute 7 from here. As described above, in this example, only empty cans are sorted through the opening 46 and fall onto the belt conveyor 8 arranged below the empty cans.

Other Embodiments The above examples apply the present invention to the case of selectively collecting and collecting empty cans from bagging waste. However, the present invention can be applied to other cases.

For example, when the treatment of wet dust is unnecessary,
The wet dust collecting device can be omitted. Further, as the bag breaking device, the primary bag breaking machine and the secondary bag breaking machine are arranged in the above example, but only one bag breaking machine may be arranged.
Furthermore, when only the bag-breaking processing of the bagging waste is performed, it is possible to use only the bag-breaking device alone. Similarly, the wet dust collector can be used alone.

Further, when the bagging waste is not the processing target, the bag breaking device may be omitted.

In addition to this, the bag-breaking device of the present invention can be applied to the case where empty cans are pressed into a rectangular block and then separated again.

[0055]

As described above, according to the present invention, the bagging waste is crushed by the bag crushing device, the wet dust is removed from the bag crushing device, and thereafter the wind-power sorting means removes mainly the empty cans from the waste. The waste containing is sorted out and only empty cans are collected from the waste using a trommel screen. Therefore, according to the present invention, the wet dust can be removed from the bagged waste and the empty cans made of aluminum and iron can be efficiently sorted and collected without resorting to manual work or the like.

Further, the bag-breaking device of the present invention has the advantages that the mechanism is simple, it is compact and can be manufactured at low cost, and the processing capacity is large for the size of the device. Further, the bag-breaking operation can be efficiently performed without the bagging waste being clogged, and the adverse effect that the bag after being broken is caught in the device can be avoided.

Furthermore, by using the wet dust collecting apparatus of the present invention, wet paper can be efficiently collected from the waste without resorting to manual work. Further, it is possible to avoid the adverse effect that the wet papers are clogged in the passage in the waste treatment device.
