Description

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 packaging material such as a plastic bag for packaging contents such as garbage and separating the contents from the packaging material. The present invention relates to a technique for collecting reusable items from a collected garbage bag.

[0002]

2. Description of the Related Art In recent years, recyclable items such as cans, bottles, plastic bottles, etc. are taken out of discharged garbage,
This is used as a resource. For example, in a garbage recycling facility, these reusable materials are collected from collected garbage bags such as plastic bags.

[0003] In the past, an operator had to manually remove the collection garbage bag to take out the contents and collect reusable items. However, since such a bag breaking operation is not easy,
There has been proposed a bag breaking device which is obtained by mechanizing this.

[0004] For example, the present applicant has previously provided a weir having a plurality of claws arranged along a moving portion, and having a slit through which each of the claws can pass and a bag containing contents is suppressed from passing. And a bag that is caught by each claw and is torn with the movement of each claw when trying to pass through the dam plate. (Japanese Patent Application Nos. 10-88049 and 10-88049).
196273 and Japanese Patent Application No. 10-222918).

[0005]

In such a bag breaking device,
The movement of the bag full of dust caught by the claws is suppressed by the blocking plate. At this time, the movement of the claws tears the bags, and discharges the torn garbage to the discharge section. At this time, it is important that the refuse is smoothly guided to the discharge unit. Otherwise, it takes time to discharge the refuse, resulting in poor processing capacity, and refuse remains in the apparatus. There is a problem that the damage of the dust is promoted in between.

On the other hand, an endless conveyor provided with a plurality of claws arranged in the moving section along the moving direction and provided so that the moving direction of the upper moving section is located at a higher position, A blocking plate having the above-described slit at the upper end of the portion, and a bag breaking device provided with a dust discharge portion at the lower end of the upper moving portion have also been proposed.
The bag caught on the nail moves up the slope of the moving part,
Torn by a claw when trying to pass through a baffle,
The refuse in the bag slides down the slope of the moving section by its own weight toward the discharge section, so that the processing time is somewhat shortened.

However, in such a bag breaking device, light dust such as styrofoam or dust such as kitchen garbage having a high friction coefficient on the contact surface cannot be slipped down by its own weight and is smoothly guided to the discharge portion. There is an inconvenience that it is difficult for him.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and smoothly guides the contents that have come out of a torn bag to a discharge section, thereby shortening the processing time. The purpose of the present invention is to provide a bag breaking device.

[0009]

According to a first aspect of the present invention, there is provided a bag breaking apparatus, comprising: a plurality of claws capable of hooking a bag and moving sequentially; And a blocking plate having a slit in which the passage of the bag containing the content of a predetermined size is suppressed, and when the bag caught on the claw tries to pass through the blocking plate, a claw is formed. A bag breaking device configured to tear the bag with the movement of the bag, and to move the contents coming out of the torn bag in a direction opposite to a moving direction of the bag to the dam plate. A nozzle is provided for creating a fluid flow from the stop plate side along the moving surface of the claw in the direction opposite to the direction of movement of the bag to the dam plate.

[0010] Such claim 1 and claim 2, which will be described later,
In each of the inventions 4 and 6, “claw” means a protrusion, hook, or the like having a square shape, a plate shape, a linear shape, or the like, and may be a linear member such as a piano wire, a steel wire, or the like. Those that are inclined or key-shaped in the moving direction are preferable. 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.

[0011] Similarly, in each invention, the flow of the fluid may be continuous or intermittent. Further, the flow direction of the fluid does not need to flow in the required direction only, and the vector component only needs to be in the required direction.For example, a large material discharge port may be provided on the side of a plate or an endless conveyor. In this case, the fluid flow may be inclined so that each vector component is directed to the required direction described in each claim and to the bulky material discharge port, etc., and the flow direction of the fluid is in the broadest sense. The concept is interpreted as follows. The bag breaking device according to claim 2, wherein the endless conveyor having a plurality of claws arranged in the moving unit along the moving direction,
A plate having a first slit through which the claw can pass is provided on the upper end of the endless conveyor along the upper end of the endless conveyor by providing a plate having a first moving direction ahead of the upper end of the endless conveyor. A second slit fixed to or integrally formed with the plate and connected to the first slit of the plate, the second slit being capable of passing the claw and suppressing the passage of a bag containing a predetermined large content. A bag breaking device provided with a blocking plate whose tip is located outside the tip of the claw passing through the second slit, wherein the lower end of the plate is placed on the plate from the blocking plate side. A nozzle for creating a fluid flow toward the side is provided.

In the invention according to claim 2, the endless conveyor having a plurality of claws arranged in the moving section is a conveyor having a continuous surface formed in a moving section such as a conveyor belt or a conveyor chain, for example, a flat top. Chain conveyors such as conveyors, apron conveyors, and bread conveyors and belt conveyors may be provided with pawls, but the moving part does not need to have a continuous surface, and is simply moved by the conveyor chain. A member provided with claws may be used.

Further, the "dam plate" does not need to be fixed to a plate by welding, bolts, nuts or the like, and may be formed integrally with the plate. . Further, the plate may be formed integrally and continuously, and the partition between the dam plate and the plate may be unclear and may be a part of the plate. Along with
It suffices if the tip of the plate is gradually curved so that the tip is located outside the tip orbit of the claw passing through the slit. Therefore, in the present specification, the term "dam plate" includes the concept of "plate dam portion" and is a concept that is interpreted in the broadest sense, including the invention according to claim 1.

According to a third aspect of the present invention, in the bag breaking apparatus according to the second aspect, at least one pair of sets including the endless conveyor, the plate, the dam plate, and the nozzle are provided so as to face each other. The endless conveyors are provided such that the lower end portions thereof approach each other at a predetermined interval, and the upper end portions thereof are most separated from each other. That is, the pair of sets was made to face each other in a substantially V shape.

According to a fourth aspect of the present invention, there is provided a bag breaking apparatus in which a moving portion is formed by a substantially continuous surface instead of the plate of the bag breaking apparatus according to the second aspect. Form a substantially continuous surface in the upper moving part between

A slit is provided, and a nozzle is provided on a substantially continuous surface of the upper moving part to create a fluid flow from the dam plate side to the lower end side of the moving part.

In the invention of claim 4, the term "substantially continuous surface" is to be understood in the broadest sense, for example, 10 mm or less, preferably 10 mm or less between a plurality of slats bridged between chains on a chain conveyor. There is no problem even if there is a gap of 5 mm or less, and a bag containing a predetermined large content may pass through the gap between the moving part and one end (lower end) of the blocking plate without being broken. Unless otherwise specified, it is a substantially continuous surface. That is, even if there is a gap on the surface of the moving unit, the surface should be a substantially continuous surface as long as the target bag can be broken by the moving unit and the dam plate.

According to a fifth aspect of the present invention, in the bag breaking apparatus according to the fourth aspect, at least one pair of sets including the endless conveyor, the dam plate, and the nozzle are provided so as to face each other, and the pair is formed. The lower end portions of the endless conveyor are arranged so as to approach each other at a predetermined interval, and the upper end portions are most separated from each other.

According to a sixth aspect of the present invention, there is provided a bag breaking apparatus in which a fixed blade is formed on a plate in place of the dam plate of the bag breaking apparatus according to the second aspect, and an endless conveyor and an upper side of the endless conveyor. A plate provided above the endless conveyor along the moving part of the endless conveyor, so that the moving end of the moving part on the upper side thereof is located at a higher position,
The upper moving portion is provided at an angle, and a plurality of claws having a toe portion directed forward in the moving direction of the upper moving portion are provided outside the moving portion, and the plate allows the pawl to pass therethrough. A bag breaking device comprising: a slit; and a plurality of fixed blades having blade portions directed rearward in a moving direction of the moving portion at a plate upper surface position on a side of the slit. A nozzle for producing a fluid flow toward the lower end of the plate is provided.

A bag breaking device according to a seventh aspect of the present invention is the bag breaking device according to the sixth aspect, wherein at least one pair of sets including the endless conveyor, the plate, and the nozzle are provided to face each other, and the pair of the endless conveyors is provided. Are arranged such that the lower end portions thereof approach each other at a predetermined interval, and the upper end portions thereof are most separated from each other.

[0020] The bag breaking device according to claim 8 is characterized in that:
In the bag breaking device according to any one of the above, the nozzle is provided between each slit of the blocking plate. A bag breaking device according to claim 9 is the bag breaking device according to any one of claims 2, 3, 6, and 7, wherein a nozzle is provided between each slit of the plate.

The bag breaking device according to the tenth aspect is the first aspect.
In the bag breaking device according to any one of (1) to (9), the claw is configured to be able to swing backward or move up and down in the moving direction of the claw according to the resistance applied to the tip of the claw by the elastic member. And

The bag breaking device according to the eleventh aspect is the first aspect of the invention.
In the bag breaking device according to any one of the tenth aspect, a compressed gas is used as the fluid. A bag breaking device according to a twelfth aspect is the bag breaking device according to any one of the first to tenth aspects, wherein a high-pressure liquid is used as the fluid.

[0023]

The operation of the present invention will be described. In the bag breaking device according to claim 1, for example, a packaging material such as a plastic bag containing contents (garbage such as cans, bottles, plastic bottles, kitchen garbage) moves from a charging chute or the like. When the bag is put into the unit, the bag is moved by being hooked on a claw provided in the moving unit. Then, the claw tries to pass through the slit of 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 claws. Can not pass.

Therefore, the bag filled with the contents is prevented from passing through the slit, while the bag caught on the nail is torn with the movement of the nail. The bag filled with the contents is prevented from passing through the slit of the blocking plate, and the bag caught on the nail is torn with the movement of the nail, and the contents are taken out of the bag (tearing action). . The bag that has come off the nail without passing through the slit is subjected to the tearing action of the subsequent nail again, and the contents are further taken out. At this time, for example, the nozzle installed near the blocking plate continuously or intermittently moves from the blocking plate side along the moving surface of the claw in the direction opposite to the moving direction of the bag to the blocking plate. Because the fluid is flowing through the bag, the contents coming out of the bag smoothly move in the direction opposite to the moving direction of the bag to the dam plate, and even if the moving speed of the claw that determines the processing capacity is increased. There is no stagnation near the dam plate or between the moving claws. On the other hand, the bag with the contents completely
Passing through the dam plate while being caught on the nail.

[0026] In the bag breaking device according to the second aspect, the endless conveyor having the moving part is arranged such that the moving direction destination on the upper side of the moving part is located at a higher position, and the moving part is disposed above the moving part. Since the plate is provided along the plate, the bag put on the plate is hooked by the claws from the lower part to the upper part between the slits provided in the plate, and is lifted upward. Then, a tearing action similar to that of the bag breaking device according to the first aspect is received. The bag which has come off the nail without passing through the slit of the baffle plate slides down on the plate, is hooked by the following nail, is again lifted upward, and is similarly subjected to a tearing action. This enables stable and continuous bag breaking operation.

The bag from which the contents have completely come out passes through the blocking plate while being caught by the nail. On the other hand, the content that has come out of the bag slips between the adjacent claws and slides down to the lower end side of the inclined plate. At this time, for example, since the fluid is continuously or intermittently flowing from the blocking plate side to the lower end side of the plate from a nozzle installed near the blocking plate or the plate, the fluid flows out of the bag. The sliding of the loaded contents toward the lower end of the plate is promoted.

That is, slippage is further promoted by being swept away by the flow of fluid from the nozzle, or friction of the contents against the plate surface is reduced by merely interposing the fluid on the plate. Even if the material is difficult to slide down due to its own weight, such as a light-weight product or a product with a high coefficient of friction on the contact surface such as kitchen waste, the friction with the plate surface can be reduced. Sliding to is promoted.

As a result, the contents easily slide down easily and smoothly, and do not stay near the dam plate or on the plate even if the moving speed of the nail for determining the processing capacity is increased. The flow of the fluid from the nozzle preferably has a high pressure and a high flow velocity, but if only the friction of the contents is to be reduced, the flow of the fluid may be such that the fluid merely intervenes on the plate. A fast flow rate is not required.

A bag breaking device according to claim 3 is provided with at least one pair of sets including an endless conveyor having a plurality of claws, a plate, a dam plate, and a nozzle, and a lower end portion of the pair of endless conveyors. The two are approaching each other at a predetermined interval, and are installed facing each other in a substantially V-shape so that the upper ends are most separated from each other. The large bag is caught by the claws on both sides and subjected to a tearing action to be torn on both sides.Therefore, the tearing action around the lower end of the plate by the claws of the endless conveyor on both sides, and the above-mentioned claw of the endless conveyor and the dam plate With the tearing action of the present invention, the endless conveyor having a plurality of claws, a plate, a damping plate and a nozzle exhibiting more than twice the bag-breaking ability as compared to the one in which only one side is arranged, For example, since the fluid is continuously or intermittently flowing from the blocking plate side to the lower end side of the plate from the nozzle installed near the blocking plate or the plate, the contents that have come out of the bag Is promoted to the lower end side of the plate, and even if the moving speed of the claw for determining the processing capacity is increased, the claw does not stay near the dam plate or on the plate. In addition, a discharge portion is formed in a valley between the plates, and the processed contents and the fluid can be intensively discharged through the discharge portion.

According to a fourth aspect of the present invention, in place of the plate of the second aspect, at least the upper moving portion of the endless conveyor is formed of a substantially continuous surface. The bag is torn by the tearing action of the claw and the dam plate as in the invention, and the contents taken out of the bag slide down on a substantially continuous slope. At this time, for example, a fluid is continuously or intermittently flown from the blocking plate side to the lower end side of the moving portion from a blocking plate or a nozzle installed near the substantially continuous surface. Therefore, the sliding of the contents coming out of the bag toward the lower end side of the moving portion is promoted, and the sliding is further promoted by being pushed by the flow of the fluid from the nozzle as in the invention according to claim 2. Or, the fluid simply intervenes on the substantially continuous surface of the moving part, so that the friction of the content against the substantially continuous surface is reduced, and the content cannot easily slide down due to its own weight and is difficult to be discharged. However, since the friction with the substantially continuous surface can be reduced, the sliding of the moving portion toward the lower end portion is promoted. As a result, even when the moving speed of the claw for determining the processing capacity is increased, the claw does not stay near the dam plate or on a substantially continuous surface of the moving portion.

According to a fifth aspect of the present invention, as in the third aspect of the present invention, an endless conveyor having a substantially continuous surface in the upper moving part and having a plurality of claws, a dam plate, and a nozzle are provided. At least one pair is provided facing each other, and the endless conveyors forming a pair are arranged facing each other in a substantially V-shape such that the lower ends thereof approach each other at a predetermined interval and the upper ends thereof are most separated from each other. As a result, the large bag dropped on the valley between the endless conveyors disposed opposite to each other in a substantially V-shape is caught by the claws on both sides and is subjected to a tearing action, so that the endless conveyors on both sides are subjected to the tearing action. Of the endless conveyor around the lower end of the endless conveyor by the claw of the endless conveyor and the tearing action of the claw of the endless conveyor and the blocking plate described above, the endless conveyor having a plurality of claws, the blocking plate, and the nozzle only on one side. As compared to the arranged one, it exerts a bag breaking ability of twice or more, and for example, from a dam plate or a nozzle installed near the substantially continuous surface, the lower end of the moving portion from the dam plate side Since the fluid is continuously or intermittently flowed toward the part, the sliding of the contents coming out of the bag toward the lower end side of the moving part is promoted, and the moving speed of the nail which determines the processing capacity is reduced. Even if it is accelerated, there is no stagnation near the dam plate or on a substantially continuous surface of the moving part. In addition, a discharge portion is formed in a valley between the endless conveyors, and the processed contents and the fluid can be intensively discharged through the discharge portion.

According to a sixth aspect of the present invention, there is provided a bag breaking apparatus in which a fixed blade is provided on an upper surface of a plate provided along an inclination of an upper moving portion of an endless conveyor, so that the bag is hooked on a claw and moves on the plate. Is broken by the cutting action of the fixed blade from the front of the bag moving direction at the bottom of the bag and the tearing action accompanying the claw movement of the bag whose movement has been suppressed by the fixed blade. The contents coming out of the bag slide down on the plate slope. At this time, for example, since the fluid is continuously or intermittently flown from the nozzle installed near the plate toward the lower end side of the plate along the plate surface, the content of the contents coming out of the bag is removed. Sliding to the lower end side of the plate is promoted, and similarly to the invention according to claim 2, even if the contents cannot slide down easily due to their own weight and are difficult to be discharged, friction with the plate surface is reduced. As a result, the plate can easily slide down, is smoothly swept down to the lower end of the plate, and does not stay on the plate even if the moving speed of the claw that determines the processing capacity is increased.

According to a seventh aspect of the present invention, in the bag breaking apparatus, at least one pair including an endless conveyor having a plurality of claws, a plate having a plurality of fixed blades, and a nozzle is provided, and the pair of endless conveyors is provided. The lower end portions of the plates are arranged facing each other at a predetermined interval, and the upper end portions are opposed to each other in a substantially V-shape such that the upper end portions are most separated from each other. The big bag that fell on
The endless conveyor on both sides is caught by the claws on both sides and is torn on both sides.Therefore, the claw of the endless conveyor on both sides tears around the lower end of the plate, and the tear of the endless conveyor claw and the fixed blade on the plate described above. By the action, an endless conveyor having a plurality of claws, a plate having a plurality of fixed blades and a nozzle having a nozzle and a nozzle arranged on only one side exhibit a bag-breaking ability twice or more, for example, a plate From the nozzle installed near the
Since the fluid flows continuously or intermittently along the upper surface of the plate toward the lower end of the plate, the contents of the bag that has flowed out of the bag are facilitated to slide toward the lower end of the plate, and the processing capacity is increased. Does not stay on the plate even if the moving speed of the claw determining the speed is increased. In addition, a discharge portion is formed in a valley between the plates, and the processed content and the fluid are
It is possible to collectively discharge through the discharge unit.

In the bag breaking device according to the eighth and ninth aspects, a plurality of nozzles are provided between the slits, that is, a plurality of nozzles corresponding to the substantially continuous surface of the plate or the moving portion between the slits. Are formed, and the fluid easily flows between the claws moving through each slit.

According to the tenth aspect of the present invention, the claw is configured to be capable of swinging or falling in the direction opposite to the moving direction according to the resistance applied to the tip of the claw. When a hard object is caught between the moving claw and the slit or the fixed blade of the blocking plate, the claw moves rearward in the moving direction when a predetermined force or more acts on the claw. Alternatively, it is possible to remove hard contents that have been caught between the fixed blade and the claw. In addition, even when a large bulky object (hard object) or the like is thrown in, the above-described biting prevention action prevents the bulky object from being caught and facilitates the movement of the claw.

According to the eleventh and twelfth aspects of the present invention, a compressed gas and a high-pressure liquid are used as fluids, so that a material such as a lightweight material such as styrene foam or a material having a high coefficient of friction on a contact surface such as kitchen garbage can slide down under its own weight. Reduce the coefficient of friction of contents that cannot be performed, promote the sliding of contents,
Enables smooth sliding.

Further, the contents can be flushed out with a strong force, and the contents can be more smoothly slid, so that the contents can be smoothly slid.

It is arranged.

The branch roller 67 is rotationally driven such that the upper cylindrical side surface thereof rotates toward a bag chute 71 described later (clockwise in FIG. 1). In this case, the branch roller 67 transmits the driving force of the drive motor for the endless conveyor by a dedicated motor separately provided from the drive motor for the endless conveyor 2 or via a transmission mechanism such as a chain or a gear. To drive.

Next, the structure of the main casing 1 in which the endless conveyor 2, the plate 3, and the dam plate 4 are disposed as described above will be described. That is, the main body casing 1
Are supported on the installation surface by the support feet 68.

As described above, the endless conveyor 2 is disposed so as to be inclined such that one side of the endless conveyor 2 in the direction perpendicular to the moving part direction is located higher than the other side. An input port is provided on one side of.
Specifically, a charging chute 69 as a charging port is provided on a side wall of the main body casing 1 on one side of the high end of the endless conveyor 2.

In this case, the input chute 69 is opened laterally (upward in FIG. 8) of the cutout chute 60. As shown in FIGS. 1 and 8
As shown in FIG. 1, a cover 1A forming a part of the main casing 1 extends obliquely downward from the outer surface of the main casing 1, covers the cutout chute 60 inside, and the other end is a lower other end of the endless conveyor 2. It is provided so as to reach the side wall of the main body casing 1 on the side of the section.

On the other side of the lower end of the endless conveyor 2, there is provided a bulky material outlet 70. That is,
On the side wall of the main body casing 1 on the side of the lower other side of the endless conveyor 2, a portion without the cutout chute 60 is formed, thereby forming a bulky material discharge port 70.

Further, a bag chute 71 serving as a discharge port is provided below the endless conveyor 2 at the bottom of the main casing 1.
And a small piece chute 72 are provided in parallel. In this case, the bag chute 71 is connected to the bag drop prevention guide 6 described above.
The small-piece chute 72 is arranged at a position corresponding to the horizontal portion 64A of each thin plate member 64 of the bag drop prevention guide 63 at a position corresponding to the lower curved portion 64C of each thin plate member 64 of No.3.

A small piece guide made of a plate member extending between the upper moving part and the lower moving part of the endless conveyor 2 and inclined toward the small piece chute 72 facing the upper moving part. 73 is provided and fixed.

In this case, small pieces such as debris that fall from the slits 3A of the plate 3 or a slight gap between the adjacent slats 18 of the endless conveyor 2 are guided.
Is provided, the slat 18 of the endless conveyor 2 on which the claw 5 is not provided may be removed.

Further, a discharge conveyor 74 is provided outside the main body casing 1 and near the lower end of the dust discharge chute 3b. Here, in the present embodiment, a cushioning material is installed at a location where the thrown bag such as the throwing chute 69 and the plate 3 collides when dropped and supplied.

That is, for example, the bag dropping position from the charging chute 69 on the upper surface of the plate 3, ie, the position shown in FIG.
As shown in FIG. 10, a rectangular iron plate 76 as a mounting plate to which a rectangular rubber plate 75 as a cushioning material is previously bonded is detachably attached to a predetermined position on the upper surface of each plate component member 50 with a bolt 77 or the like. Attach fixedly.

In this case, both the rubber plate 75 and the iron plate 76 have insertion holes 75A, 76A for the bolt 77 at the same position, and the insertion hole 76A on the iron plate 76 side has a smaller diameter than the insertion hole 75A on the rubber plate 75 side. It is formed.

Further, a thread groove 50A of the bolt 77 is formed on the plate component member 50 side. Further, the rubber plate 75
Is set to a thickness such that the head of the bolt 77 is housed without protruding.

According to such a mounting structure of the rubber plate 75, the following advantage is obtained by the structure in which the iron plate 76 to which the rubber plate 75 is previously bonded is detachably fixed to the upper surface of the plate component 50.

That is, when the rubber plate 75 is directly bonded to the upper surface of the plate member 50, when the rubber plate 75 is replaced, the old rubber plate 75 is peeled off, the plate member 50 is polished, and a new rubber plate 75 is bonded. A process of waiting until completion is required, but if the iron plate 76 to which the rubber plate 75 is bonded in advance is detachably fixed to the upper surface of the plate component 50, the old rubber plate 75 can be removed together with the iron plate 76. It is a simple process of removing and attaching an iron plate 76 with a new rubber plate 75.

The bending angle of the above-mentioned claw 5 and the blocking plate 4
The width and the like of the slit 4A will be described later in detail. Next, the operation of the bag breaking device having such a configuration will be described.

For example, packaging materials such as plastic bags containing garbage (cans, bottles, plastic bottles, kitchen garbage, etc.)
78 is the input chute 69 to the plate 3
It is dropped into the upper surface of the rubber plate 75 (FIG. 11A)
reference).

In this case, when the bag 78 is dropped on the upper surface of the rubber plate 75, the impact at the time of dropping is reduced, and damage such as cans, bottles, and plastic bottles in the bag is prevented. Then, the bag 78 is hooked by the claws 5 from the lower portion to the upper portion between the slits 3A provided in the plate 3 and is lifted upward. The claw 5 tries to pass through the slit 4A of the fixed dam plate 4 while the bag 78 is hooked (see FIG. 11B).

Those that can pass through the slit 4A of the blocking plate 4 are smaller than the slit 4A width,
The hard garbage such as cans, bottles, and plastic bottles wider than the slit 4A cannot pass through the slit 4A only by a soft material such as the bag 78 hooked on the slit 4A.

Therefore, the bag 78 filled with garbage is not
A while the passage of A is suppressed, the bag 7 caught on the nail 5
8 is torn with the movement of the nail 5 (FIG. 11 (C),
(D)).

The bag 78 filled with such garbage is formed by the slit 4A.
Is suppressed, and the bag 78 caught on the nail 5 is repeatedly torn by the nail 5 several times, so that the bag 78 is torn, and the dust 78A comes out of the bag 78.

The bag 78 from which the dust 78A has completely come out passes through the blocking plate 4 while being caught by the claws 5, and is drawn into the lower moving portion of the endless conveyor 2, and is subjected to the action of gravity. It falls to the bag chute 71.

The garbage 78A that has come out of the bag 78 passes through between the adjacent claws 5 and falls to the bottom of the inclined plate 3, passes through the interval 61 (discharge portion), and is disposed below the discharge portion. It is conveyed to the next processing step by the conveyor 74.

Here, in this embodiment, the plate 3 and the endless conveyor 2 are arranged so that one side in the direction perpendicular to the moving direction of the claw 5 is positioned higher than the other side. Then, a charging chute 69 for the bag 78 is provided above the plate 3 on the higher side. For this reason, the bag 78 that has fallen off the nail 5 and falls down along the inclination of the plate 3 while the bag is incompletely broken, or the bag 78 in which a smaller bag is contained therein, repeats the number of drops. Then, the plate 3 moves to a position closer to the other side of the plate 3 located at a lower position, that is, a direction approaching a bulky material discharge port 70 provided at the lower side of the plate 3, and the claw 5 provided in this direction. And the blocking plate 4 repeatedly acts to break the bag,
Is discharged from

At this time, the refuse 78A that has come out of the bag 78 is pushed away by the high-pressure water from the nozzle 91 disposed above the dam plate 4, so that the refuse 78A slides and the light refuse 7A is discharged.
8A or 78A with high friction coefficient on the contact surface
However, the friction with the surface of the plate 3 is reduced, so that the plate 3 smoothly slides and is discharged onto the discharge conveyor 74.

Here, the claw 5 has an elastic member (torsion coil spring 22), and is configured to be swingable or tiltable in the backward direction in the moving direction according to the resistance applied to the toe portion 5A. As a result, when a hard object is caught between the claw 5 protruding from the plate 3 and the blocking plate 4, when a force greater than a predetermined force acts on the claw 5, the claw 5 moves in the direction of being inserted into the slit 3A. The hard material caught between the dam plate 4 and the claw 5 is removed, the hard material falls on the plate 3 by the action of gravity, and reaches the discharge conveyor 74 from the dust discharge chute 3b, and from there, It is discharged outside the device.

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 FIGS. 13A and 13B, the nail 5 in a state of rising toward the hard object 79 larger than the slit 4A advances. As shown in FIG. 3C, when the hard object 79 bites between the claw 5 and the dam plate 4, the claw 5 rotates rearward in the traveling direction against the elastic force of the elastic member. Fall down.

As shown in FIG. 14D, when the claw 5 rotates, the hard material 79 escapes from between the claw 5 and the blocking plate 4, while the claw 5 is in the slit 4 A of the blocking plate 4. Proceed through. By such an operation, the hard material 79 that has been caught between the blocking plate 4 and the claw 5 can be removed, and processing can be continuously performed without damaging the claw 5 and the blocking plate 4.

When a coarse material (hard material) or the like larger than the gap portion 61 (discharge portion) is supplied, the coarse material is prevented from being caught by the above-described biting prevention action. However, since the one side part in the direction orthogonal to the moving direction is arranged at an inclination higher than the other side part, the bulky object is moved upward by the claw 5 by the claw 5 and blocked by the claw 5 in the apparatus. Due to the falling from the vicinity of the plate 4, the vertical movement is repeatedly received, and it is sent in a direction gradually approaching the bulky material discharge port provided on the lower side of the endless conveyor 2, and is discharged out of the apparatus from the bulky material discharge port 70. .

[0117] Here, the hook 5
The bag 78 that has passed through the slit 4A is drawn into the lower moving portion of the endless conveyor 2 and falls onto the bag chute 71 by the action of gravity. However, some of the bags 78 may not fall on the bag chute 71 but remain hooked on the claws 5.

The bag 78 still caught on the nail 5
Is pulled by the claw 5 on the bag drop prevention guide 63, passes through the upper moving portion of the endless conveyor 2, and is again drawn into the lower moving portion, and the bag chute 71 by the action of gravity. Get the opportunity to fall into.

That is, the bag falling prevention guide 63 prevents the bag 78 that does not fall to the bag chute 71 from falling to other than the bag chute 71, and ensures that the bag 78 falls to the bag chute 71 side. Thus, the ability to sort the bags 78 is improved.

Further, a branch roller 67 is provided which extends in the horizontal direction along the direction in which the ends of the thin plate members 64 of the bag drop prevention guide 63 on the side of the lower curved portion 64C are arranged in parallel.
This is rotatably driven so that the upper moving part is rotated toward the bag chute 71 side, so that the moving part on the boundary between the bag chute 71 and the small piece chute 72 does not fall toward the bag chute 71. Bag 7 that falls to a nearby position
8 is forcibly carried to the bag chute 71 side by the rotation of the branch roller 67, and the bag 78 falls to a position near the boundary between the bag chute 71 and the small piece chute 72,
The bag 78 is prevented from being caught here, and the bag 78 can be reliably dropped onto the bag chute 71.

At the end of the bag falling prevention guide 63 at the position of the lower curved portion 64C of each thin plate member 64 away from the moving portion of the claw 5, the bag 78 is clogged between the adjacent thin plate members 64. There is a possibility that the branch roller 67
Is provided close to the end of each thin plate member 64 of the bag drop prevention guide 63 on the side of the lower curved portion 64C, so that the branch roller 67 allows each thin plate member 64 of the bag fall prevention guide 63 to be closed. The bag does not reach the end position on the side of the lower curved portion 64C, and the bag 78 is prevented from being clogged between the adjacent thin plate members 64 at this position.

Further, small pieces 80 such as dust that have fallen out of the slits 3A of the plate 3 usually slide on the slats 18 at the upper moving section of the endless conveyor 2 to cause the small piece chute 7 to slide.
2 and the slats 1 of the endless conveyor 2
The small piece 80 that has fallen between the upper moving part and the lower moving part of the endless conveyor 2 from the gap between the small parts 8 directly drops toward the lower moving part of the endless conveyor 2. Then, the other portion is dropped and received on the upper surface of the small-piece guide 73, and slides down on the upper surface of the small-piece guide 73 to drop toward the lower moving portion of the endless conveyor 2.

The dropped small pieces 80 further pass through the gap between the lower moving portion of the endless conveyor 2 and the gap between the thin plate members 64 of each set of the bag drop prevention guide 63 and the gap between each set. It falls into the chute 72.

By providing the small piece guide 73,
Slats 18 of the endless conveyor 2 without the claws 5
Is removed, the dropped small pieces 80 can be reliably dropped into the small piece chute 72, and the configuration of the endless conveyor can be simplified. That is, the small piece 80 that has fallen between the upper moving part and the lower moving part of the endless conveyor 2 from the slat 18 removing part is partially replaced by the slat 1 of the lower moving part.
8 Drops directly toward the removal section, and the other
3, fall on the upper surface of the small piece guide 73, slide down on the upper surface of the small piece guide 73, and fall toward the slat 18 removing portion of the lower moving portion,
Eventually, a small piece shoot 72 is reached.

As described above, the bag 78 filled with garbage is used.
Is prevented from passing through the slit 4A of the dam plate 4, the bag 78 caught on the claw 5 is torn with the movement of the claw 5, and the bag 78 is torn by repeating such an operation several times. The trash goes out of the bag 78 (tearing action).

[0125] Of the bags subjected to such a tearing action, regardless of the bags that have been completely torn out by being torn, or the bags in which dust remains in the middle of the tearing action, a part of the bags is formed by the blocking plate 4. With the slit 4A passing through and the remaining portion not passing through the slit 4A of the blocking plate 4, the end (tip) of the blocking plate 4 on the opposite side of the claw 5 from the passing side (base end). It may be in a state of being caught on the side.

When the operation of the bag breaking device is continued, the bag clogged at this end is pushed by the bag clogged at the end of the slit 4A by the pushing action of the claw 5 toward this end. When it reaches the open part of the end, it comes off from here.

The above-mentioned detached bag falls on the plate 3 and
The dropped bag is again caught by the claw 5 and is carried in the direction of the slit 4A of the dam plate 4, and is subjected to "tearing action", so that stable and continuous bag breaking operation is possible.

Further, in the present embodiment, the slit 4A is provided at the tip (the slit 4) on the side opposite to the side where the claw 5 passes.
A is formed so that the slit width gradually increases toward the tip of the claw 5 passing through the tip A).
The passage resistance of the bag when moving the slit 4A is reduced,
The bag clogged in the slit 4A can be quickly pushed out.

That is, as described above, the bag that has already been clogged at the distal end side by the bag that is newly packed toward the distal end side opposite to the side where the claw 5 of the slit 4A has passed opens the distal end portion. In the action of being pushed out toward the set portion, for example, a configuration in which the claw 5 has an elastic member and is configured to be able to swing or fall in the movement direction rearward in accordance with the resistance applied to the toe portion thereof is used. The bag clogged in the slit 4A moves by being pushed by the elastic force of the elastic member. During this time, the bag is in a compressed state, and when moving through the slit 4A, the passage resistance of the bag increases according to the compression pressure, but the slit width is formed so as to gradually increase toward the tip end. Therefore, the passage resistance of the bag when moving through the slit 4A is reduced, and the bag clogged in the slit 4A is quickly pushed out.

In this embodiment, the slit 4
A bag that traverses in the slit width direction at a position in the vicinity of the tip end opposite to the passing portion of the claw 5 of A and facing the back surface of the blocking surface of the blocking plate 4 at a predetermined interval. Since the weir 57 for prevention is provided, even if the part where the dust of the bag remains tries to go around the open part of the end of the dam plate 4, the weir 57 prevents the sneak movement. You.

Even in this blocked state, the nail 5 passes through the slit 4A with the bag pulled off or with the bag removed.
Eventually, the bag falls. In the case where the plate 3 having the slit 3A through which the nail 5 can pass is provided as in the present embodiment, the bag separated from the nail 5 falls on the plate 3,
The dropped bag is caught by the claws 5 again, carried in the direction of the slit 4A of the dam plate 4, and subjected to "tearing action", whereby stable and continuous bag breaking operation becomes possible.

The other operations of the embodiment described above are as follows. Since the dam plate 4 and the plate 3 are integrally formed, no biting occurs at this portion.

Further, since the claw 5 is attached to the upper side of the slat 18 along the moving direction of the endless conveyor 2, maintenance of the claw 5 is facilitated. Also,
The side wall of the mounting seat 19 of the claw 5 shown in the embodiment of FIGS. 2 to 5 is formed in a substantially trapezoidal shape having an inclined surface 19A which becomes lower toward the front in the moving direction of the endless conveyor 2, for example. In the case where the input foreign matter has a string like a water bottle, the main body of the water bottle is blocked by the dam plate 4, and the string enters the slit 3 </ b> A of the plate 3 and goes into the mounting seat 19 of the claw 5. Even in the event of being caught, the string is easy to slip out of the mounting seat 19, so that the risk of an emergency stop of the device can be minimized.

Further, since the claw 5 shown in the embodiment of FIG. 6 is attached to the lower side of the slat 18 which is the moving portion of the endless conveyor 2, unnecessary protrusions and depressions are formed on the upper side of the slat 18 which is the moving portion. This can be avoided as much as possible, and there is no possibility that dirt coming out of the bag that has passed through the slit of the plate 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 dimensions and the like of each part in the bag breaking apparatus having the above configuration will be described with reference to FIG. The nail 5 may be linear, but in this embodiment, the toe 5A of the nail 5 is bent in the moving direction of the nail 5, and the bending angle θ is 30 ° to 80 °, preferably 45 ° -60
° range is good.

As the bending angle θ approaches 60 °,
Since it is easy for the claws 5 to hook the bag 78, the bag breaking efficiency is increased. If the angle is smaller than the above range, the claw 5
As a result, the bag 78 can be easily hooked and damaged, and the time required for breaking the bag becomes longer. That is, the processing capacity decreases.

When the angle is larger than the angle in the above range, when the solid is caught between the blocking plate 4 and the claw 5, the claw 5
It is difficult to smoothly release solids even when the slab moves, and as a result, trash is damaged.

The length a of the bent portion is 10 mm to 50 mm.
mm, preferably in the range of 25 mm to 35 mm. If the length a of the bent portion is shorter than the length in the above range, the bag 78 can be easily caught by the claws 5, and the time required for breaking the bag becomes longer. That is, the processing capacity decreases.

[0175]

As described above, according to the bag breaking device of the first aspect, in particular, the direction of movement of the bag from the side of the blocking plate to the blocking plate along the moving surface of the claw is opposite. The nozzle has a nozzle for creating a flow of fluid in the direction, so that the fluid allows the contents to move smoothly in the direction opposite to the moving direction of the bag to the dam plate, and the movement of the claw that determines the processing capacity Even if the speed is increased, there is no stagnation near the dam plate or between the moving claws, so the required processing time can be shortened, and the damage to the refuse generated while the refuse remains in the apparatus can be suppressed, and the entire apparatus can be suppressed. Can be improved.

In the bag breaking device according to the second aspect, the endless conveyor having the moving portion is arranged such that the moving direction of the upper moving portion is located at a higher position, so that the content is reduced by its own weight. Although it slides down to the lower end of the plate, it is pushed further by the fluid from the nozzle to further promote slipping, or the fluid merely intervenes on the plate to reduce the friction of the contents against the plate surface It is possible to reduce the friction with the plate surface, even if it is a content that is difficult to slide down due to its own weight, such as a lightweight material such as Styrofoam or a material with a high friction coefficient on the contact surface such as kitchen garbage. Sliding toward the lower end of the plate is promoted.

As a result, the plate easily slides smoothly to the lower end side of the plate, and does not stay near the dam plate or on the plate even if the moving speed of the claw for determining the processing capacity is increased. Therefore, in addition to the sliding due to the weight of the contents, the sliding is promoted by the flow of the fluid, or the friction with the plate surface is reduced by merely interposing the fluid on the plate, and the sliding of the contents is promoted. In addition, the residence time of the contents after the bag breakage can be greatly reduced, the damage of the contents occurring during the residence can be suppressed, and the processing capability of the entire apparatus can be improved.

[0178] In the bag breaking device according to claim 3, the set including the endless conveyor having a pair of claws, the plate, the dam plate, and the nozzle is formed in a substantially V shape. Due to the installation facing each other, tearing action around the lower end of the plate by the claws of the endless conveyor on both sides,
Due to the tearing action of the claws of the endless conveyor and the blocking plate described above, more than twice as many breaks as those of the endless conveyor having a plurality of claws, plates, blocking plates and nozzles arranged on only one side. It is possible to exert the bag ability. Moreover, the fluid from the nozzle facilitates the sliding of the contents discharged from the bag toward the lower end of the plate, thereby improving the processing capacity of the entire apparatus and forming a discharge portion in a valley between the plates. The processed contents and the fluid can be intensively discharged through the discharge portion. For example, when the fluid is a liquid, batch processing of the fluid is enabled.

In the bag breaking device according to the fourth aspect, similarly to the bag breaking device according to the second aspect, the fluid from the nozzle facilitates the sliding of the contents coming out of the bag toward the lower end of the moving portion. Is done. Therefore, in addition to the sliding due to the weight of the contents, the sliding is promoted by the flow of the fluid, or the friction with the substantially continuous surface is reduced by merely interposing the fluid on the substantially continuous surface of the moving portion. The sliding of the contents is promoted, and even if the moving speed of the claw that determines the processing capacity is increased, the contents do not stay near the dam plate or on the substantially continuous surface of the moving portion, and the contents after the bag breakage The residence time can be significantly reduced, the damage to the contents occurring during the residence can be suppressed, and the processing capacity of the entire apparatus can be improved. This also eliminates the need to provide a plate.

According to a fifth aspect of the present invention, as in the third aspect of the present invention, an endless conveyor having a plurality of claws, a substantially continuous surface, a dam plate, and a nozzle are formed on the upper moving portion. Are set so as to face each other so as to form a substantially V-shape, so that tearing action around the lower end of the endless conveyor by the pawls of the endless conveyor on both sides and tearing action by the pawls and the dam plate of the endless conveyor described above. Thus, it is possible to exhibit more than twice the bag breaking ability as compared with an endless conveyor having a plurality of claws, a dam plate, and a nozzle arranged on only one side. Moreover, the fluid from the nozzle facilitates the sliding of the contents that have come out of the bag toward the lower end of the moving section, thereby improving the processing capacity of the entire apparatus and the discharge section at the valley between the endless conveyors. The formed and processed contents and the fluid can be intensively discharged through the discharge portion. For example, when the fluid is a liquid, batch processing of the fluid is enabled.

In the bag breaking device according to the sixth aspect, the fixed blade is provided on the upper surface of the plate provided along the upper moving portion of the endless conveyor. At the same time as the cutting action is received by the fixed blade, when the movement of the bag by the fixed blade is inhibited, the tearing action is caused by the movement of the claws, so that continuous bag breakage becomes possible. Further, the bag torn by the cutting action of the fixed blade is more likely to be caught on the nail, and is effectively hooked on the subsequent nail to further advance and repeatedly receive the tearing action.

Further, similar to the bag breaking device according to claim 2,
Fluid from the nozzle facilitates sliding of the contents exiting the bag towards the lower end of the plate. Therefore, in addition to the sliding due to the weight of the contents, the sliding is promoted by the flow of the fluid, or the friction with the plate surface is reduced by merely interposing the fluid on the plate, and the sliding of the contents is promoted. Even if the moving speed of the claw that determines the processing capacity is increased, the claw does not stay on the plate even if the moving speed is increased, so that the residence time of the contents after the bag breakage can be greatly reduced, and the damage of the contents caused during the retention can be suppressed. At the same time, the processing capability of the entire apparatus can be improved.

The bag breaking device according to claim 7 is obtained by installing a set including an endless conveyor having a plurality of claws, a plate having a plurality of fixed blades, and a nozzle so as to form a substantially V-shape. The tearing action around the lower end of the plate by the claw of the endless conveyor on both sides and the tearing action by the claw of the endless conveyor and the fixed blade on the plate described above allow the endless conveyor having a plurality of claws and the plurality of fixed blades. It is possible to exhibit twice or more the bag-breaking ability as compared to the case where the provided plate and nozzle are arranged on only one side. Moreover, the fluid from the nozzle facilitates the sliding of the contents coming out of the bag toward the lower end of the plate,
Along with improving the processing capacity of the entire apparatus, a discharge portion is formed in a valley between the plates, and the processed contents and the fluid can be intensively discharged through the discharge portion.
For example, when the fluid is liquid, batch processing of the fluid is enabled.

In the bag breaking device according to the eighth and ninth aspects, since a plurality of nozzles are provided between the slits, the bag passes and the fluid flows along the substantially continuous surface of the plate or the moving portion, which is the moving surface of the nail. Flows, the fluid flows to the part of the contents that cannot slide down due to its own weight and remains on the slope of the endless conveyor,
Thereby, the sliding of the contents is promoted.

According to the bag breaking device of the tenth aspect, it is possible to remove the hard contents caught between the slit or the fixed blade and the claw of the dam plate, and a large coarse material (hard material) or the like can be removed. Even when thrown in, the bite of the bulky object is prevented by the above-mentioned bite prevention action, but by flowing a fluid substance toward the claw, the removal of hard contents becomes easier. In addition, biting of a bulky object is further prevented.

The eleventh aspect of the present invention uses a compressed gas as a fluid to reduce the friction coefficient of contents that cannot slide down under their own weight, such as a lightweight material such as styrene foam or a material having a high friction coefficient on a contact surface such as kitchen garbage. Can be reduced, and the sliding of the contents is promoted, and smooth sliding is enabled.

Further, the contents can be pushed away with a strong force, and the sliding of the contents is further promoted, so that a smooth sliding is enabled. Further, as compared with the case where the fluid is a liquid or the like, it has a favorable effect from the viewpoints of maintenance of the endless conveyor and discharge processing of the fluid.

According to the twelfth aspect of the present invention, by using a high-pressure liquid as a fluid, only a small amount of liquid intervenes on the contact surface, the friction is reduced, and the sliding of the contents is promoted. It is possible to reduce the coefficient of friction of contents that cannot be slid down by its own weight, such as a light-weight material or a material having a high friction coefficient on a contact surface such as kitchen garbage, thereby facilitating the sliding of the contents and enabling smooth sliding.

Further, the contents can be pushed away with a stronger force than the compressed air, so that the contents can be more smoothly slid, and smooth sliding can be achieved.
