DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag breaking device for breaking a wrapping material such as a plastic bag for wrapping garbage and separating the garbage and the like from the wrapping material. The present invention relates to a technology that is effective when collecting reusable materials from a collection garbage bag such as a garbage bag.

[0002]

2. Description of the Related Art In recent years, garbage recycling facilities for recycling recyclable materials, such as cans, bottles, and plastic bottles, out of collected garbage, use plastic bags and other collected garbage bags. These reusable materials are collected from inside. In the past, workers used to manually collect and collect recyclable garbage bags to collect reusable items.However, it is not easy to break such bags. Proposed.

For example, in Japanese Patent No. 256131385, as shown in FIG. 16, each of a plurality of endless conveyors 60 is provided with angular projections 61 at a predetermined pitch, and the endless conveyor 60 is provided on the conveyor from above. A holding plate 62 is provided at an appropriate position facing the surface 60 and swingable in the traveling direction of the conveyor 60. The holding plate 62 elastically suppresses the movement of the garbage bag that is caught by the projection 61 and sent. In addition, there is disclosed a bag opening / closing device in which a receiving plate 63 for receiving the waste, which is the opened contents, is provided in parallel with the conveyor 60.

[0004]

However, in the bag breaking technique disclosed in Japanese Patent No. 2561385, at least the pressing plate 62 is movable with a lower pressure than at least the projection 61. If a hard object is bitten between 62, push the holding plate 62
The hard object is also scraped up together with the projection 61.

[0005] Therefore, when the hard object in the bag is bitten, the hard object passes through the holding plate 62 together with the bag, and the unprocessed bag is discharged from the apparatus. In addition, since the contents of the torn bag are discharged between the plurality of endless conveyors 60 to which the protrusions 61 are attached, the small bags are
Often, the bag itself gets stuck in the space between adjacent endless conveyors 60.

In such a case, the bag cannot sufficiently receive the pressure of the holding plate 62 and the projection 61, and the contents are scraped upward without being taken out of the bag. Is discharged from Furthermore, in addition to the contents packed in the packaging material (especially when waste is subject to disposal),
When a large foreign substance or the like is thrown into the apparatus, the foreign substance or the like may be caught between the projection 61 and the pressing plate 62, and the apparatus may be stopped in an emergency.

[0007] This is a bag breaking method in which the progress of the packaging material caught on the projection 61 is suppressed by the pressing plate 62 and the further protruding projection 61 tears the packaging material. When a foreign matter is caught between the pressure plate and the pressure plate, the holding plate 62 is swung to release the force. For this reason, when foreign matter having a size exceeding the swing range of the holding plate 62 is thrown into the apparatus, the foreign matter is lifted by the advancing projection 61 and swings with the projection 61 to the maximum swing range. It is caught between the holding plate 62 and the holding plate 62.

As a result, the progress of the projection 61 is hindered,
The driving device of the conveyor 60 to which the projection 61 is attached is stopped due to an electrical overload. Further, the operation of removing the foreign matter that has been cut by the mechanical force for driving the conveyor 60 to which the projection 61 is attached may require a lot of time and labor, and as a result, the whole plant is stopped and the continuous equipment is stopped. Can not be operated, and there is a problem that bag breaking work efficiency is poor.

SUMMARY OF THE INVENTION The present invention has been made in view of the above technical problems, and is capable of breaking a packaging material without being limited by the size of a packaging material such as a plastic bag for packaging garbage. At the same time, it is possible to avoid as much as possible a situation in which untreated waste is discharged without breaking, and even if a large foreign substance or the like is accidentally thrown in, continuous operation can be performed without interrupting the operation of the apparatus. It is an object of the present invention to provide an efficient bag-breaking device, for example, in which bagging is possible.

Move Direction and the opposite side is constituted respectively swingably or raised or lowered capable to said.

According to the first and second aspects of the present invention, the endless conveyor having the plurality of claws arranged along the moving portion has a continuous surface formed in the moving portion such as a conveyor belt or a conveyor chain. Conveyors, for example, flat top conveyors, apron conveyors, chain conveyors such as bread conveyors and belt conveyors provided with pawls, but a moving surface thereof does not need to have a continuous surface, and is simply a chain. A member provided with a claw may be provided.

[0013] The "claw" means a projection, a hook or the like having a square, plate, or linear shape, and may be a linear member such as a piano wire or a steel wire. It is preferable to be inclined or hooked. In short, any material may be used as long as the tip bites into a part of the packaging material such as a bag and hooks the packaging material, or the tip contacts the packaging material and breaks the packaging material by shearing force.

According to a third aspect of the present invention, the endless conveyor is disposed so as to be inclined such that one side of the endless conveyor in a direction orthogonal to the moving portion is positioned higher than the other side. An inlet is provided on the side of the unit. The invention according to claim 4 is characterized in that a bulky material discharge port is provided on the other side of the endless conveyor at a lower position.

The invention according to claim 6 is characterized in that the endless conveyor has a structure in which a substantially continuous surface is formed at least in an upper moving portion between a lower end and an upper end.

In the invention according to claim 6, the structure in which a continuous surface is formed at least in the upper moving portion between the lower end portion and the upper end portion is, for example, a flat top conveyor, an apron conveyor, a pan conveyor, or the like. Chain conveyors and belt conveyors are exemplified. In the invention according to claim 7, the claw is mounted on a moving portion of an endless conveyor via a mounting seat, and a side wall of the mounting seat is
It is characterized by being inclined or curved so as to become lower as it goes in the direction of movement of the endless conveyor.

The moving part means a chain, a crossbar, a slat, an apron, a pan or a pallet in a chain conveyor, a belt in a belt conveyor, and the like. The invention according to claim 8 is characterized in that the claw is attached to a lower side of a moving portion of the endless conveyor, with a tip portion of the claw upper side.

The operation of the present invention will be described. Claim 1
In the invention according to the invention, for example, when a packaging material (hereinafter simply referred to as a bag) such as a plastic bag containing garbage (cans, bottles, plastic bottles, kitchen garbage, etc.) is thrown in from a throwing chute or the like, the bag is inclined. It falls on a plate placed on the endless conveyor, and is caught by a claw from a lower portion to an upper portion between slits provided in the plate, and is lifted upward. The claws try to pass through the slits in the fixed dam plate while the bag is hooked.

Only slits smaller than the slit width, that is, soft nails and bags that are hooked on the nails, can pass through the slits of the blocking plate. I can't pass. Therefore, the bag filled with dust is suppressed from passing through the slit, while the bag caught on the nail is torn with the movement of the nail.

[0020] The bag is torn and the garbage comes out of the bag while the bag filled with the garbage is suppressed from passing through the slit and the bag caught on the claw is repeatedly torn by the claw several times. The bag from which the garbage has completely come out passes through the blocking plate while being caught by the claws, and is drawn into the lower moving section of the endless conveyor, and by the action of gravity,
For example, it falls to a discharge chute.

The refuse coming out of the bag slips through between the adjacent claws, falls to a discharge portion at the lower end of the inclined plate, and is discharged out of the apparatus by, for example, a discharge conveyor disposed below the plate. In particular, in the invention according to claim 1,
As a result of the claw having an elastic member and being configured to be capable of swinging or falling in the direction opposite to the moving direction according to the resistance applied to the toe portion, the claw on the endless conveyor and the slit of the dam plate are formed. When a hard object is caught in between, when a force greater than a predetermined force acts on the claw, the claw moves in a direction in which the claw is inserted into the slit, so that the hard object caught between the slit of the blocking plate and the claw. Is removed and the hard object falls to the bottom side of the endless conveyor by the action of gravity, and is discharged out of the apparatus by, for example, a discharge conveyor disposed below the endless conveyor.

Further, even when a large object (hard object) or the like larger than the discharge portion at the lower end of the plate is thrown in, the above-mentioned bite preventing action prevents the bite of the large object.
In the invention according to claim 2, when the bag is thrown in from a throwing chute or the like, the bag is valley between plates installed on each endless conveyor installed facing each other so as to be inclined so as to form a substantially V shape. The bag that has fallen on the part and fallen is caught on each claw from the lower part to the upper part between the slits provided in the plate of each endless conveyor, and with the movement of each claw of both endless conveyors, for example, The bottom of the bag is torn on both sides and the debris in the bag is discharged.

The discharged garbage falls toward the valley,
The sheet is discharged from the discharge section between the two plates to the outside of the apparatus by, for example, a discharge conveyor disposed below the discharge section. Of the bags that have been torn as described above, the larger ones and those that have been broken into two or more are hooked on the claws of both endless conveyors,
Alternatively, one of the torn bags which is strongly caught by the claw of one endless conveyor is caught by this one claw and is scraped upward. The claws try to pass through the slits in the fixed dam plate while the bag is hooked.

The slits of the blocking plate can only pass through the slits smaller than the slit width, that is, only soft nails and bags that are hooked on the nails. I can't pass. Therefore, the bag filled with dust is suppressed from passing through the slit, while the bag caught on the nail is torn with the movement of the nail.

The bag is torn and the garbage comes out of the bag while the bag filled with the garbage is suppressed from passing through the slit and the bag caught on the nail is repeatedly torn by the claw several times. The bag from which the garbage has completely come out passes through the blocking plate while being caught by the claws, and is drawn into the lower moving section of the endless conveyor, and by the action of gravity,
For example, it falls to a discharge chute.

The refuse coming out of the bag slips through between the adjacent claws, falls to a discharge portion at the lower end of the inclined plate, and is discharged out of the apparatus by, for example, a discharge conveyor disposed below the plate. In the bag breaking apparatus according to the second aspect of the present invention, the endless conveyors are disposed on both sides of the endless conveyor. By the action of the present invention, an endless conveyor is arranged on one side of the invention according to the first aspect, and the bag-breaking device capable of breaking the bag more than twice as much as the bag-breaking device that breaks the bag by the action of the claw and the dam plate. .

Further, in the invention according to claim 2,
As a result of the claw having an elastic member and being configured to be capable of swinging or falling in the direction opposite to the moving direction according to the resistance applied to the toe portion, the claw on the endless conveyor and the slit of the dam plate are formed. When a hard object is caught in between, when a force greater than a predetermined force acts on the claw, the claw moves in a direction in which the claw is inserted into the slit, so that the hard object caught between the slit of the blocking plate and the claw. Is removed and the hard object falls to the bottom side of the endless conveyor by the action of gravity, and is discharged out of the apparatus by, for example, a discharge conveyor disposed below the endless conveyor.

Further, even when a large object (hard object) or the like larger than the discharge portion at the lower end of the plate is supplied, the above-described biting prevention action prevents the large object from being caught.
In the invention according to claim 3, the endless conveyor is disposed so as to be inclined such that one side portion in a direction orthogonal to the moving portion direction is located higher than the other side portion, and the side of the higher one side portion is provided. The bag opening is provided at the end of the endless conveyor, and the bag that has fallen off the nail and falls down along the slope of the endless conveyor, or a smaller bag inside The dropped bag is moved in the direction of the other side of the endless conveyor located at the lower position, for example, in the invention according to claim 4, in the direction approaching the bulky material discharge port provided on the side of the lower end of the endless conveyor. It falls and is repeatedly subjected to the bag breaking action by the action of the claw and the dam plate provided in this direction.

In this case, even if a large material (hard material) or the like larger than the discharge portion at the lower end of the plate is supplied, the large material repeats up and down movement in the apparatus to gradually lower the other end of the endless conveyor. It is sent in a direction approaching the bulky material discharge port provided on the side of the section, and is discharged out of the apparatus from the bulky material discharge port. In the invention according to claim 5, since the blocking plate and the plate are integrally formed, biting between the blocking plate and the plate is eliminated. In addition, since these integrally formed products can be supported below the plate, above the blocking plate, and on the sides thereof, the supporting strength of the plate and the blocking plate can be increased.

By the way, when the plate and the blocking plate are separate bodies, the plate with the slit has a structure to be supported only below and on the side, and similarly, the blocking plate with the slit has the structure above and on the side. And the support strength of the plate and the dam plate is inferior to that of the configuration of the present invention. In the invention according to claim 6, the endless conveyor has a structure in which a continuous surface is formed at least in the upper moving portion between the lower end portion and the upper end portion, that is, for example, a flat top conveyor, an apron conveyor, a pan conveyor, and the like. The hooks on the chain conveyor, belt conveyor, etc. are structured so that the gap between the slits provided on the plate goes from the lower part to the upper part, so small debris that has passed through the slits on the plate may be scattered. Instead, it falls while sliding on the continuous surface of the endless conveyor, and is discharged toward the discharge portion, for example, by a discharge conveyor disposed below the discharge portion.

It should be noted that the above-mentioned substantially continuous surface means that the above-described action occurs even if there is a gap of 10 mm or less, preferably 5 mm or less between the slats and the surface is not completely continuous. In, the continuous surface is to be understood in the broadest sense, and the presence of the gap is also a substantially continuous surface. In the invention according to claim 7, the nail is
The claw is easily maintained by being mounted on the upper side of the moving portion of the endless conveyor via the mounting seat.

Further, since the side wall of the mounting seat of the claw is inclined or curved so as to become lower as it goes toward the end of the moving direction of the endless conveyor, for example, a string such as a water bottle is provided as the foreign matter that has been input. Even if the water bottle body is blocked by the blocking plate, and the string should get into the slit of the plate and get caught on the mounting seat of the claw, the string is easy to slip out of the mounting seat, The possibility of an emergency stop can be minimized.

In the invention according to claim 8, the claw is attached to the lower end of the moving portion of the endless conveyor with the tip thereof on the upper side, so that unnecessary irregularities are avoided as much as possible above the moving portion of the endless conveyor. As a result, there is no possibility that a bag passing through the slit of the plate or small debris coming out of the bag may be caught, as in the case where the claws are attached to the upper side of the slat through the attachment seat.

Accordingly, the bag 31 filled with dust is suppressed from passing through the slit 4A, while the bag 31 hooked on the claw 5 is torn with the movement of the claw 5 (see FIGS. 8C and 8D).

The bag 31 filled with such garbage has a slit 4A.
Is repeated and the action that the bag 31 hooked on the nail 5 is torn by the nail 5 is repeated several times, the bag 31 is torn, and the dust 31A comes out of the bag 31. The bag 31 from which the refuse 31A has completely exited passes through the blocking plate 4 while being caught by the claws 5, and is drawn into the lower moving section of the endless conveyor 2, and the discharge chute 28 is acted on by gravity. To fall.

The refuse 31A that has come out of the bag 31 slips through between the adjacent claws 5 and falls to the bottom of the inclined endless conveyor 2, and is disposed below the space 25 (discharge unit) through the space 25 (discharge unit). The paper is discharged out of the apparatus by the discharge conveyor 29.
Here, in the present embodiment, the endless conveyor 2 is disposed so as to be inclined such that one side portion in a direction orthogonal to the moving portion direction is positioned higher than the other side portion, and Since the input chute 27 of the bag 31 is provided on the side, the bag 31 that has come off from the claws 5 and falls down along the slope of the endless conveyor 2 while the bag breaking is incomplete or a smaller bag inside the bag 31 The bag 31 similarly dropped in the inserted state is directed to the other side of the endless conveyor 2 located at a lower position, that is, the direction approaching the bulky material discharge chute 30 provided on the lower side of the endless conveyor 2 at the other side. , And is repeatedly subjected to the bag breaking action by the action of the claw 5 and the blocking plate 4 provided in this direction.

Here, the claw 5 has an elastic member (a torsion coil spring 22) and is configured to be swingable or tiltable in the direction opposite to the moving direction according to the resistance applied to the toe 5A. As a result, the claw 5 on the endless conveyor 2 and the dam plate 4
When a hard object is caught between the claws 5 and a predetermined force or more acts on the claw 5, the claw 5 moves in a direction to be inserted into the slit 3 </ b> A, and is caught between the dam plate 4 and the claw 5. The hard material is removed, and the hard material falls to the bottom side of the endless conveyor 2 by the action of gravity, passes through the space 25 (discharge portion), and is discharged out of the apparatus by the discharge conveyor 29 disposed below the space portion 25 (discharge portion). You.

Therefore, the processing can be continuously performed without damaging the claw 5 and the dam plate 4. The operation of removing the hard object will be described with reference to FIG. As shown in FIG. 3A, a hard object 3 larger than the slit 4A is formed.
The nail 5 raised toward 2 advances.

As shown in FIG. 6B, the claw 5 and the dam plate 4
When the hard object 32 bites in between, the claw 5 rotates in a direction opposite to the traveling direction against the elastic force of the elastic member and falls down.
As shown in FIG. 3C, when the claw 5 rotates,
The hard object 32 escapes from between the claw 5 and the dam plate 4. Accordingly, as shown in FIG. 3D, the claw 5 advances through the slit 4A of the dam plate 4.

By such an operation, the hard material 32 caught between the blocking plate 4 and the claw 5 can be removed, and the processing can be continuously performed without damaging the claw 5 and the blocking plate 4. Further, when a coarse material (hard material) or the like larger than the interval portion 25 (discharge portion) is input, the large-size material is prevented from being caught by the above-described biting prevention action, and the endless conveyor 2 has Since one side portion in the direction perpendicular to the moving portion direction is disposed so as to be higher than the other side portion, the bulky material is moved upward by the claw 5 by the claw 5 and the blocking plate 4 in the apparatus. Repeated up and down movement by falling from the vicinity,
It is gradually fed in a direction approaching a bulky matter discharge chute 30 provided on the lower side of the endless conveyor 2 on the other side, and is discharged from the bulky matter discharge chute 30 to the outside of the apparatus.

Further, in the present embodiment, the dam plate 4
And the plate 3 are integrally formed, so that no biting occurs at this portion. Further, since these integrally formed products can be supported below the plate 3, above the blocking plate 4, and on the sides thereof, the plate 3 and the blocking plate 4 of the plate 3 and the blocking plate 4 can be supported. Support strength can be increased.

Incidentally, when the plate 3 and the dam plate 4 are separate bodies, the plate 3 having the slit 3A has a structure to be supported only below and on the side.
The blocking plate 4 with A has a structure to support only above and on the side, and the supporting strength of the plate 3 and the blocking plate 4 is inferior to the structure of the present invention. In the present embodiment, the adjacent slats 18 are connected to the conveyor chain 1.
In an upper moving portion between at least a lower end portion and an upper end portion of the endless conveyor 2 other than the portion where the first and second portions are bent,
Since the end faces are close to each other and the slats 18 are configured to form one substantially continuous surface as shown in FIG. 4, the small dust 3 passing through the slit 3A of the plate 3 is formed.
1A slides down on the continuous surface of the slat 18 without being scattered, falls toward the discharge section, and can be discharged out of the apparatus by a discharge conveyor 29 disposed below the discharge section.

It should be noted that even if there is a gap of 10 mm or less, preferably 5 mm or less between the slats and the surface is not a completely continuous surface, the above-described action occurs. You can consider it. Further, in the present embodiment, maintenance of the claw 5 is facilitated by mounting the claw 5 on the upper side of the slat 18 along the moving portion of the endless conveyor 2.

The nail 5 shown in the embodiment of FIGS.
The side wall of the mounting seat 19 is formed in a substantially trapezoidal shape having an inclined surface 19A that becomes lower as it goes in the direction of movement of the endless conveyor 2, and has, for example, a string as a water bottle as a charged foreign substance. In the case, the main body of the water bottle is blocked by the baffle plate 4, and even if the cords enter the slits 3A of the plate 3 and are caught on the attachment seats 19 of the claws 5, the cords easily slip out of the attachment seats 19. ,
The risk of an emergency stop of the device can be minimized.

The claw 5 shown in the embodiment of FIG. 7 is attached to the lower side of the slat 18 which is the moving part of the endless conveyor 2, so that unnecessary unevenness is formed on the upper side of the slat 18 which is the moving part. This can be avoided as much as possible, and there is no possibility that a bag that has passed through the slit of the plate or small debris that has come out of the bag, as in the case where the claw 5 is mounted on the upper side of the slat 18 via the mounting seat, will be caught.

Next, the bag breaking device of the second embodiment is shown in FIG.
It will be described based on. In this embodiment, two endless conveyors 2 and 2 ′ each having a plate 3 and a dam plate 4 are provided, and the moving directions of the upper moving parts are located at higher positions, and The lower end portions are arranged to face each other at a predetermined interval, and the upper end portions are arranged to face each other such that the upper end portions are most separated from each other. That is,
Both endless conveyors 2, 2 'are installed facing each other at an angle so as to form a substantially V-shape.

Similarly to the first embodiment, each of the endless conveyors 2 and 2 'is arranged so as to be inclined so that one side in the direction orthogonal to the moving part direction is located higher than the other side. Is established. The configurations of the plate 3 and the dam plate 4 provided on each of the endless conveyors 2 and 2 'are the same as those of the first embodiment. Description is omitted.

In this embodiment, the hanging portions 3b of the plates 3 of the endless conveyors 2 and 2 'are opposed to each other via a predetermined interval 33 serving as a discharge portion. next,
The structure of the main casing 1 in which the two endless conveyors 2 and 2 ', each plate 3 and each dam plate 4 are disposed will be described. That is, the main body casing 34 is supported on the installation surface by the support feet (not shown).

As described above, each endless conveyor 2, 2 '
Are arranged so that one side in the direction orthogonal to the direction of the moving part is positioned higher than the other side, and is located on the side of the higher side of both endless conveyors 2 and 2 ′. A side wall of a certain main body casing 34, wherein both endless conveyors 2, 2 '
A charging chute 35 is provided at the intermediate position. In this case, the charging chute 35 is opened in a space defined by the plates 3 of the endless conveyors 2 and 2 '.

A discharge chute 36 is provided below the endless conveyors 2, 2 'at the bottom of the main casing 34, respectively. Further, a discharge conveyor 37 is disposed below the space (discharge unit) 33 at the bottom of the main body casing 34. The discharge conveyor 37 is disposed so as to be inclined along the length direction of the interval section (discharge section) 33.

Although not shown, both endless conveyors 2,
A bulky material discharge chute as a bulky material discharge port is provided on the side wall of the main body casing 34 on the side of the other lower side of 2 'and between the endless conveyors 2 and 2'. Next, the operation of the bag breaking device having such a configuration will be described. When the bag 31 is inserted from the input chute 35, the bag
The bags 31 that have fallen and fall into the valleys between the plates 3 installed on the endless conveyors 2 and 2 ′, which are installed facing each other so as to form a letter shape, are dropped. '
Between the slits 3A provided in the plate 3 is caught by each of the claws 5 from the lower part to the upper part. For example, the bottom of the bag 31 is torn with the movement of each of the claws 5 of the endless conveyors 2, 2 '. Thus, the refuse 31A in the bag 31 is discharged.

The discharged garbage falls toward the valley,
The paper is discharged from the space (discharge part) 33 between the plates 3 to the outside of the apparatus by a discharge conveyor 37 disposed below the space. Of the bags 31 torn at the lower ends of the endless conveyors 2 and 2 'as described above, a large one or two or more torn pieces are hooked on the claws 5 of the endless conveyors 2 and 2', or The one of the endless conveyors 2 or 2 'which is strongly caught by the claw 5 of the torn bag 31 is caught by the claw 5 and is lifted upward. The claw 5 tries to pass through the slit 4A of the fixed dam plate 4 while the bag 31 is hooked.

In each of the endless conveyors 2 and 2 ′, what can pass through the slit 4 A of the dam plate 4 is smaller than the width of the slit 4 A, that is, the claw 5 and the soft bag such as the bag 31 hooked on it. Hard dust larger than the width of the slit 4A alone cannot pass through the slit 4A. Therefore, the bag 31 filled with dust is suppressed from passing through the slit 4A, while the bag 31 hooked on the nail 5 is torn with the movement of the nail 5.

The bag 31 filled with such garbage has a slit 4A.
The bag 31 is torn and the garbage comes out of the bag 31 while repeating the action of suppressing the passage of the bag 31 and causing the bag 31 hooked on the nail 5 to be torn by the nail 5 several times.
The bag 31 from which the garbage has completely come out passes through the blocking plate 4 while being caught by the claws 5, is drawn into the lower moving portion of the endless conveyor 2, 2 ′, and is discharged by the action of gravity. It falls to the chute 36.

The refuse 31A that has come out of the bag 31 slips through between the adjacent claws 5 and falls to the bottom of the inclined endless conveyors 2 and 2 ', and the discharge conveyor 37 disposed below the endless conveyors 2 and 2'.
Is discharged out of the apparatus. The bag breaking device in which the endless conveyors 2 and 2 'are arranged on both sides of the second embodiment has a tearing action around the lower end of the plate 3 by the claws 5 of the endless conveyors 2 and 2' on both sides as described above. (3) By the action of the claw 5 and the dam plate 4 around the upper end portion, the bag-breaking device exerts approximately twice the bag-breaking capacity as compared with the bag-breaking device in which the endless conveyor 2 is arranged on one side in the first embodiment. .

The functions and effects of the second embodiment other than those described above are the same as those of the first embodiment.
Next, the dimensions and the like of each part in the bag breaking device of the first embodiment and the bag breaking device of the second embodiment having the above configuration will be described with reference to FIG. The nail 5 may be linear, but in the present embodiment, the toe 5A of the nail 5 is used.
Is bent in the moving direction of the claw 5, and the bending angle θ
Is in the range of 30 ° to 80 °, preferably 45 ° to 60 °.

As the bending angle θ approaches 60 °,
Since it is easy for the claws 5 to hook the bag 31, the bag breaking efficiency is increased. If the angle is smaller than the above range, the claw 5
As a result, the bag 31 can be easily hooked and damaged, and the time required for breaking the bag increases. That is, the processing capacity decreases. At an angle larger than the angle in the above range, it is difficult to smoothly release the solid matter even when the claw 5 is movable when the solid matter is caught between the blocking plate 4 and the claw 5. And, as a result, damage to the refuse.

The length a of the bent portion is 10 mm to 50 mm.
mm, preferably in the range of 25 mm to 35 mm. When the length a of the bent portion is shorter than the length in the above range, the bag 31 is easily caught by the claws 5 and is easily damaged, and the time required for breaking the bag becomes longer. That is, the processing capacity decreases.

If the length a of the bent portion is longer than the above range, there is the following problem. That is, in order for the swinging claw 5 to pass smoothly without contacting the slit 4A of the dam plate 4, the locus of the tip of the swinging claw 5 is farthest from the surface of the endless conveyor 2 perpendicular to the end. The slit length corresponding to the length to the position is necessary, and as the length a of the bent portion increases, a portion of the slit 4A of the dam plate 4 through which the claw 5 does not pass when the claw 5 is not in the swinging state. Becomes longer.

As the portion of the slit 4A through which the nail 5 does not pass is longer, the chance of being scraped off by the nail 5 in a normal state is reduced, and the bag 31 tends to remain entangled with the slit 4A (apparatus). Although it does not hinder the operation of). In addition, the size of the dam plate 4 itself becomes excessively large by the length of the slit. Further, the thickness b of the nail is preferably as thin as the strength of the nail allows, but for example, about 3 mm to 10 mm is realistic.

Next, the relationship between the dam plate 4 and the endless conveyor 2 (plate 3) will be described. The angle φ between the dam plate 4 and the plate 3 is set to 60 to 100 degrees, preferably 70 to 85 degrees. In this case, the dam plate 4 and the endless conveyor 2
When the angle φ with the (plate 3) is an acute angle (less than 90 degrees), the bag 31 entangled with the slit 4A of the dam plate 4
Makes it easier to scrape off.

That is, the bag 31 carried by the claw 5 is pressed against the blocking plate 4, and
A, but when the angle φ between the blocking plate 4 and the plate 3 is made acute, the bag 31 pressed against the blocking plate 4 by the claw 5 receives the reaction of the blocking plate 4, Since the plate 3 is pressed and held by the plate 3 without escaping from the dam plate 4, it can be accurately hooked with the claw 5.

Further, the relationship between the claw 5 and the dam plate 4 will be described. The nail effective length c which is the vertical height of the nail above the plate 3 of the nail 5 is set to 100 mm to 200 mm. The optimum value of the nail effective length c of the nail 5 differs depending on the size of the bag 31. If there is a width in the size of the bag 31 to be processed, it is also effective to combine nails 5 of several lengths.

The slit width d of the blocking plate 4 is set to a range in which only the claws 5 and the broken bag 31 pass, and is 15 mm to 40 m.
m is preferably 20 mm to 35 mm. The gap between the claw 5 and the slit 4A of the blocking plate 4 is 5 m on each side of the claw.
m or more is preferably secured. When the slit width d is small, it is difficult for the broken bag 31 to pass through the slit 4A of the dam plate 4, and the smooth discharge of the broken bag 31 is not performed. Causes a decline.

When the slit width d is large, the slit 4
Garbage passes through the bag A together with the bag 31, and an incompletely broken bag with the bag 31 still containing the dust is generated. Further, since the tip of the claw 5 is inclined, the inclined claw 5 can smoothly pass without contacting the slit 4 </ b> A of the blocking plate 4. A minimum slit length is required, and the distance e between the slit 4A of the blocking plate 4 and the tip of the claw 5 does not matter if it is too narrow. When passing through the slit 4A, the passing area is widened, and the passage of the bag 31 becomes easier.

Next, the relationship between the plate 3 and the claw 5 will be described. The gap between the claw 5 and the slit 3A of the plate 3 is (thickness of claw 5 + 0 mm to 30 mm), preferably (thickness of claw 5 + 10 mm to 20 mm). This gap is
It is preferable that the size is as small as possible within a range where the claw 5 can smoothly pass through the slit 3A of the plate 3. If this gap is too large, large dust easily falls from the slit.

Next, the plate 3 in the first embodiment
A space (discharge portion) 25 between the hanging portion 3b of the cutting chute 24 and the hanging portion (discharge portion) 33 between the hanging portions 3b of both plates 3 in the second embodiment will be described. The smaller the gaps 25 and 33 are as far as possible within a range in which the garbage to be treated can be discharged, the less the small bag containing the garbage is discharged without being caught by the claws 5.

When the target is garbage, such as cans, bottles, and plastic bottles, the above-mentioned interval f is 150 mm to 4 mm.
00 mm, preferably 180 mm to 280 mm. In the above embodiment, the example in which only the plurality of claws 5 are provided on the endless conveyors 2 and 2 ′ is shown. However, the present invention is not limited to this, and the bag 31 may be cut in place of some of the plurality of claws 5. It is a matter of course that a blade that can be used may be provided.

In the above embodiment, the claws 5 and the coil springs 20 and 22 as elastic members are formed separately, but the claws and the coil springs as elastic members are formed of the same wire. It may be one integrated. In this case, the coil spring portion may be engaged with the claw seat while being inserted and supported by the pin, and the wire portion protruding from the coil spring portion may be the claw portion.

Further, in the above embodiment, the moving portions of the endless conveyors 2, 2 'are formed linearly.
As shown in FIGS. 1 and 12, an endless conveyor having a moving portion whose intermediate portion is convex downward and concaved upward, and a moving portion whose intermediate portion is concave downward and convex upward as shown in FIG. It may be. In an endless conveyor as shown in FIGS. 11 to 13, since there is a curved moving part, FIG.
Chain guides 40 and 41 as shown in FIG.
The chain 11 is arranged above and below, and is configured to be guided along the moving part while bending the chain 11.

Further, in the case where two endless conveyors 2 and 2 'are provided as in the second embodiment, the moving portions of both endless conveyors 2 and 2' may have the same shape or different shapes. Also, the moving speed of the two endless conveyors 2, 2 '
The same speed is preferred, but may be different. further,
The garbage discharge conveyors 29 and 37 do not need to be installed independently, but extend a conveyor for transferring garbage to the next process to a lower part of the discharge unit, and the garbage discharge conveyors 29 and 37.
37 may also be used.

In the above embodiment, the configuration in which the endless conveyor 2 is installed so as to face the cutout chute 24 and the configuration in which the two endless conveyors 2 and 2 'are installed so as to face each other have been described. A cutting device, for example, rolls 64 and 65 in FIG. In the above embodiment, small debris that has passed through the slits 3A of the plate 3 is removed from the slats 1 of the endless conveyors 2, 2 '.
8 slides down and falls to the discharge conveyors 29 and 37, but the endless conveyor 2
While removing the slat 18 on which the 2 ′ claw 5 is not provided, a small-piece discharging chute may be provided between the upper moving part and the lower moving part of the endless conveyor 2, 2 ′.

Here, when the plate 3 and the blocking plate 4 are formed separately, the following configuration can be considered as a measure against biting of a hard object between the claw 5 and the blocking plate 4. That is, the dam plate 4
In the direction orthogonal to the direction of movement of the endless conveyors 2, 2 ',
In other words, a plurality of dividing means are provided in the lateral direction, and each of the divided dam plates 4B is provided with a swinging means for swinging with the end opposite to the plate 3 as a fulcrum, and a slit 4C is provided (see FIG. 15).

In this case, each of the divided blocking plates 4B is arranged such that its tip is close to the plate 3, its end is rotatably supported, and its tip is attached to the inner wall of the main body casing 1 by the rocking means. And supported by a spring 38. Further, a rod-shaped stopper (not shown) for restricting the rotation of each of the divided damming plates 4B by the elastic force of each spring 38 is provided.

According to this configuration, the divided dam plate 4B is
When a hard object is caught between the blocking plate 4 and the plate 3 as a result of being fixed movably in the circumferential direction around the fulcrum at the end, a set force acts on the divided blocking plate 4B. Then, it can move and release the bite, so that the processing can be continuously performed without stopping the apparatus. In addition,
The setting conditions for the movement of the claw and the blocking plate (divided blocking plate) are generally set as follows, assuming that there is no trouble such as operation of the apparatus and damage.

Claw: Set so as not to damage dust. Dam plate: Set so that the rotating drum does not stop due to electrical overload. The acting force is set as "claw <dam plate". The blocking plate is set so as not to move when the slit is bitten. Such an operation will be described with reference to FIG.

As shown in FIG. 11A, the claw 5 in the state of rising toward the hard object 39 advances. As shown in FIG. 2B, the hard object 39 bites between the claw 5 and the slit 4A of the blocking plate 4. As shown in FIG. 4C, the hard member 39 causes the divided dam plate 4B to move the spring 3
8 against the elastic force of the second damper, ie, the divided dam plate 4B
Defeat and proceed.

As shown in FIG. 11D, after the hard object 39 has passed between the plate 3 and the divided blocking plate 4B, the divided blocking plate 4B is returned to the original position by the elastic force of the spring 38. Return. By such an operation, processing can be continuously performed without stopping the apparatus.

Further, since the blocking plate 4 is configured to be divided into a plurality of parts, when a hard object is caught, only the divided blocking plate 4B in which the hard object is caught is movable, and the other divided blocking members 4B are movable. The plate 4B functions without being affected by the influence, and a reduction in processing capacity can be minimized.
