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.

[0003] In the past, workers have manually collected and collected recyclable garbage bags to collect reusable items. However, since the operation of breaking such bags is not easy, a mechanically crushed garbage bag is used. Bag devices have been proposed.

[0004] For example, the present applicant has previously disclosed an endless conveyor having a plurality of claws arranged outside the moving section at intervals along the moving direction. In addition to providing a moving direction destination is located at a higher position, a blocking plate having a slit through which each nail row can pass and the passage of a bag containing contents is provided, and a bag hooked on each nail is provided. There have been proposed various bag-breaking devices based on a structure in which the bag is torn by a claw when trying to pass through a slit of a dam plate (Japanese Patent Application No. 10-1962).
No. 73 and Japanese Patent Application No. 10-222918).

[0005]

By the way, in such a bag breaking device, the bag is detached from the nail while the bag breaking is incomplete and falls down along the inclination of the endless conveyor. Move the endless conveyor, such as a conveyor belt or conveyor chain, so that small bags that are thrown into the bag with the small bag inside and fall out of the outer bag that has fallen and fall off are repeatedly subjected to the bag breaking action. One side (one of the sides perpendicular to the direction of movement of the claw) is inclined and disposed so as to be positioned higher than the other side, and a bag injection chute is provided on the side of the higher one side In this way, the dropped bags fall in the direction of the other side of the endless conveyor located at the lower position, that is, in the direction approaching the discharge port of the bulky material provided on the side of the lower end of the endless conveyor. ,
The bag breaking action of the claws and the blocking plate provided in this direction can be repeatedly received.

[0006] However, it has been found that the following problems occur in the configuration in which the endless conveyor is arranged inclining as described above. That is, according to the inclined arrangement of the endless conveyor, for example, a drive shaft, a sprocket, and the like, which constitute a drive unit of the endless conveyor, are naturally arranged at an inclination. This is inferior in durability and causes a problem in maintenance of the apparatus as compared with the case where the endless conveyor is arranged horizontally.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned technical problems, and has an endless conveyor having a plurality of claw rows in which a plurality of claws are arranged outside a moving portion at intervals along a moving direction. In the upper moving part, while providing so that the moving direction destination of the claw is located at a higher position, a dam plate having a slit through which each nail row can pass and the passage of the bag containing the content is suppressed. A bag breaking device based on a configuration in which a bag hooked on each claw is torn by a claw when trying to pass through a slit of a blocking plate. A configuration in which one side of the moving unit is inclined so as to be positioned higher than the other side is abolished, and instead, the arrangement of the claws in the endless conveyor is devised to maintain and maintain the apparatus. The problem above Without aims to make breakage is subjected to breakage action bag repeatedly dropped downward along the inclination of such endless conveyor remains incomplete.

A bag breaking device which is provided with a blocking plate having: a bag which is caught by each claw and which is torn with movement of each claw when trying to pass through the blocking plate, wherein the endless On the side of one side of the moving part of the conveyor (one of the sides perpendicular to the claw moving direction), the bag charging section is provided, while each of the claws in the plurality of nail rows on at least the one side is In the positional relationship between the two closest nails, the nail moves The nails located on the front side with respect to the direction are the nails of the nail row on the one side, and the nails located on the rear side are the nails on the nail row on the other side. I do.

According to a second aspect of the present invention, in the first aspect of the present invention, a large-size discharging section is provided on the other side of the moving section of the endless conveyor.

[0010] The invention according to claim 3 is the invention according to claim 1 or 2.
In the invention described in the above, a plate having a slit through which the claw can pass is provided above the endless conveyor along a moving portion on the upper side of the endless conveyor, while the dam plate is fixed to or integrally with the plate. The plate is formed continuously and has the slit connected to the slit of the plate, and the tip is located outside the tip of the nail passing through the slit.

[0011] In the invention according to claim 3, as the endless conveyor having a plurality of claw rows in which a plurality of claws are arranged outside the moving portion at intervals along the moving direction, a moving member such as a conveyor belt or a conveyor chain is used. Conveyor having a continuous surface formed in a part, for example, a flat top conveyor, an apron conveyor, a chain conveyor such as a bread conveyor or a belt conveyor provided with claws, but a continuous surface is formed in a moving part thereof. It is not necessary to provide a claw simply on a member moved by the conveyor chain.

Further, the "dam plate" need not be one in which an independent part as an article is fixed to a plate by welding, bolts, nuts, or the like, but may be formed integrally with the plate. . Further, the plate may be integrally formed continuously with the plate, and the partition between the dam plate and the plate may be unclear and may be a part of the plate. ,
It suffices that the tip is located outside the tip of the nail that passes 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.

[0013] The invention according to claim 4 is the invention according to claim 1 or 2.
In the invention described in the above, the endless conveyor has at least a substantially continuous surface formed at an upper moving portion between a lower end portion and an upper end portion, and the blocking plate has one end portion of a moving portion of the endless conveyor. Touching or approaching the substantially continuous surface,
The other end is located outside the upper moving part.

In the invention according to claim 4, a substantially continuous surface is formed at least in the upper moving portion between the lower end portion and the upper end portion, and the plurality of claws are spaced outside the moving portion along the moving direction. An endless conveyor having a plurality of arranged nail rows, for example, a flat-top conveyor, an apron conveyor, a chain conveyor or a belt conveyor such as a bread conveyor, the nails such that the nail tips are located outside the moving part. Provided.

According to a fifth aspect of the present invention, in the invention according to any one of the first to fourth aspects, two endless conveyors are provided, and the two endless conveyors have their lower end portions mutually separated. It is characterized in that the upper end portions are opposed to each other at a predetermined interval, and the upper end portions are most separated from each other, and the claw and the dam plate are provided for each endless conveyor.

Further, in the invention according to claims 1 to 5, the "claw" means a projection, a hook or the like having a square shape, a plate shape, a linear shape or the like, for example, a wire such as a piano wire or a steel wire. It may be shaped like a member, and it is preferable that the tip is inclined in the moving direction of the claw or has a hook shape. 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 sixth aspect of the present invention, in the invention according to any one of the first to fifth aspects, an imaginary line connecting the closest claws is formed in the upper moving part of the endless conveyor. And an angle in the range of 110 to 150 degrees with respect to the moving direction of the claw.

The operation of the present invention will be described. Claim 1
In the bag breaking apparatus according to any one of the above-mentioned items 6, for example, a packaging material such as a plastic bag containing garbage (cans, bottles, plastic bottles, kitchen garbage, etc.) (hereinafter simply referred to as a bag) is charged with a charging chute or the like. When the bag is thrown in from the section, the bag falls on an inclined endless conveyor or a plate installed on the endless conveyor, and a gap from a lower portion of the endless conveyor to a claw or a plate provided on the plate from a lower portion to a lower portion. It is hooked by the claws heading upward and is lifted up. The claw tries to pass through the slit of the fixed dam plate while the bag is hooked, but the slit that can pass through the slit of the dam plate is smaller than the slit width, that is, the claw and the hook Hard garbage or the like that is larger than the slit width and cannot be passed through the slit is only a soft material such as a bag that has been removed.

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. Such a bag full of dust is suppressed from passing through the slit of the dam plate, and the bag caught on the nail is torn with the movement of the nail, and the bag is torn by repeating such an operation several times. The garbage comes out of the bag (tearing action).

Further, the bag which has come off from the nail without passing through the slit falls on the endless conveyor or the plate, and the dropped bag is again hooked on the nail and carried in the direction of the slit of the dam plate. , Subject to tearing action. This enables stable and continuous bag breaking operation.

The bag from which the dust has completely come out passes through the blocking plate while being caught by the claws, is drawn into the lower moving section of the endless conveyor, and is moved by gravity to, for example, a discharge chute. Fall.

The garbage that has come out of the bag slips through between the adjacent claws and falls to the discharge section at the lower end of the inclined endless conveyor.
Alternatively, the sheet passes through between the adjacent claws and falls to the discharge portion at the lower end of the inclined plate, and is conveyed to the next processing step by, for example, a discharge conveyor provided below the plate.

Here, in the moving section of the endless conveyor,
At least the nails in the plurality of nail rows on one side (the side orthogonal to the nail moving direction) where the bag input section is located close to the nail moving direction in the positional relationship between the two closest nails. The nails located on the front side are arranged so that the nails on one side are the nails on the side, and the nails located on the rear side are the nails on the side of the other side. The bag that has come off from the nails while trying to fall down along the slope of the plate or endless conveyor, but is immediately caught by the nails of the nail row on the other side located closest to the rear, Bounces up on

The bag caught on the nail on the other side moves the center of gravity toward the other side by being supported by the nail.
Also, in the case of the jumping bag, the claws closest to each other are arranged diagonally downward on the other side, and when jumping, they hit a plurality of claws arranged diagonally below and collide with the other side. A component force of the reaction is provided. Therefore, there is a strong tendency that the direction of the jump is on the other side. As described above, the bag is repeatedly moved to the other side and does not stay in the input portion by repeatedly catching and hitting the claw located at the rear side and jumping up. The bag is repeatedly broken by the action of the stop plate.

At this time, if a large-size discharge section is provided on the other side of the moving section of the endless conveyor as in the second aspect of the present invention, large-size articles other than bags filled with dust can be removed. Even if they are put together, the closest claws are arranged diagonally downward on the other side, so that the plurality of claws arranged diagonally below repeatedly repeatedly lift up and move the other side. It is carried to the department side and reaches the outlet for bulky items.

Therefore, the bulky material is discharged without stagnation, so that the bag-breaking action is not hindered by the bulky material, so that the treatment can be performed smoothly. In particular, as in the invention according to claim 3, a plate having a slit through which a claw can pass is provided above the endless conveyor along a moving portion such as a conveyor belt or a conveyor chain on the upper side of the endless conveyor, and a dam is provided. Since the plate is fixed or integrally formed integrally with the plate and has a slit connected to the slit of the plate, hard garbage such as a can such as a can can bite between the plate and the blocking plate. There is no waste, and small debris that has come out of the bag slides down on the plate surface and goes to the discharge part.

Similarly, in claim 4, 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 portion and an upper end portion.
For example, flat top conveyor, apron conveyor,
The pawls on chain conveyors such as bread conveyors and belt conveyors are structured so that the claws go from the lower part to the upper part, so small debris that comes out of the bag slides down on the almost continuous surface of the endless conveyor. And head to the discharge section.

The "substantially continuous surface" in claim 4 means that, even if there is not a completely continuous surface with a gap of 10 mm or less, preferably 5 mm or less between each slat, Therefore, in the present specification, the “substantially continuous surface” is to be understood in the broadest sense, and the presence of the gap is also a substantially continuous surface.

Further, in the invention according to claim 5, when the bag is thrown in from a throwing chute or the like, the bag is installed on each endless conveyor which is installed so as to face in an inclined manner so as to form a substantially V shape. Falls on the valleys between the endless conveyors, or between endless conveyors if there are no plates.

In the case where the plate is provided, the dropped bag is caught by the claws from the lower part to the upper part between the slits provided in the plates of the endless conveyors, and the bags are moved by the claws of both endless conveyors. Accordingly, for example, the bottom of the bag is torn on both sides, and dust in the bag is discharged.

The discharged garbage falls toward the valley,
The sheet is discharged from the discharge portion between the two plates to the outside of the apparatus by, for example, a discharge conveyor provided below the plate. 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 of the fixed dam plate while the bag is hooked, and are subjected to the tearing action described above.

Further, the bag that has come off the nail without passing through the slit falls on the plate, and the dropped bag is again hooked on the nail and transported in the direction of the slit of the dam plate, and has a tearing action. receive. This enables stable and continuous bag breaking operation.

The bag from which the dust has completely come out passes through the blocking plate while being caught by the claws, is drawn into the lower moving portion of the endless conveyor, and is moved to, for example, a discharge chute by the action of gravity. Fall.

The refuse that has come out of the bag passes through between the adjacent claws and falls to a discharge portion at the lower end of the inclined plate, and is conveyed to the next processing step by, for example, a discharge conveyor provided below the plate.

In the case without a plate, the dropped bag is
In each endless conveyor, each claw is hooked from the lower part to the upper part. With the movement of each claw of both endless conveyors, for example, the bottom of the bag is torn on both sides, and dust in the bag is discharged.

The garbage discharged falls toward the valley,
The paper is discharged from the discharge portion between the endless conveyors to the outside of the apparatus by, for example, a discharge conveyor provided therebelow. The large or two or more pieces of the bags torn as described above may be caught by the claws of both endless conveyors, or may be caught by one endless conveyor of the torn bags. The strong one is hooked on this one claw and is lifted up. The claws try to pass through the slits of the fixed dam plate while the bag is hooked, and are subjected to the tearing action described above.

Further, the bag which has come off the nail without passing through the slit falls on the endless conveyor, and the dropped bag is again hooked on the nail and carried in the direction of the slit of the dam plate.
Subject to tearing action. This enables stable and continuous bag breaking operation.

The bag from which the dust has completely come out passes through the blocking plate while being caught by the claws, is drawn into the lower moving section of the endless conveyor, and is moved to, for example, a discharge chute by the action of gravity. Fall.

The refuse coming out of the bag falls to a discharge portion at the lower end of the inclined endless conveyor, and is conveyed to the next processing step by, for example, a discharge conveyor provided therebelow. The bag breaking device according to the fifth aspect of the present invention, having a plate, includes a tearing action near the lower end of the plate by the claws of the endless conveyor on both sides as described above, and a claw and a dam plate around the upper end of the plate. By the action of (1), a plate and an endless conveyor are arranged on one side, and the bag-breaking ability is more than twice as large as that of the bag-breaking apparatus which breaks the bag by the action of the claw and the dam plate.

In the case without a plate, the endless conveyor pawls on both sides as described above tear the sheet around the lower end of the conveyor and the claw and dam plate near the upper end of the conveyor to endlessly move only one side. As compared with a bag breaking device in which a conveyor is arranged and the bag is broken by the action of the claws and the blocking plate, this also exhibits a bag breaking capacity of more than twice.

Further, in the invention according to claim 6,
Since the imaginary line connecting between the closest nails is formed at an angle in the range of 110 to 150 degrees with respect to the moving direction of the nail, the action of the arrangement of the closest nails is achieved,
That is, the above-mentioned bag does not stay in the charging section, and the effect of repeatedly receiving the bag breaking action by the action of the claw and the blocking plate provided in this direction is more effectively exerted.

It is arranged.

The branch roller 67 is rotationally driven so that the upper cylindrical side surface thereof rotates toward the bag chute 71 described later (clockwise in FIG. 2). 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 arranged 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 substantially horizontally so that one side and the other side in a direction orthogonal to the moving section direction are located at substantially the same height. On the side of one side of the conveyor 2, a charging section is provided.
Specifically, a charging chute 69 as a charging unit is provided on a side wall of the main casing 1 on one side of the endless conveyor 2.
Is provided.

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

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

Further, a bag chute 71 as a discharge port is provided at a position below the endless conveyor 2 at the bottom of the main body 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.

[0100] Between the upper moving part and the lower moving part of the endless conveyor 2, a small piece guide composed of a plate member extending toward the small piece chute 72 so as to face the upper moving part and to incline toward the small piece chute 72. 73 is provided and fixed.

In this case, small pieces such as dust falling from the slits 3A of the plate 3 and 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 bagging 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 through holes 75A, 76A for the bolt 77 formed 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 screw 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 bonded in advance is detachably fixed to the upper surface of the plate constituting member 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 step 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 from the iron plate 76. It is a simple process of removing and attaching a new rubber plate 75.

The bending angle of the claw 5 and the dam 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, a packaging material (hereinafter referred to as a plastic bag) 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, since the bag 78 is dropped on the upper surface of the rubber plate 75, the impact at the time of dropping is reduced, and breakage of dust, 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).

The slits 4A of the blocking plate 4 can pass through the slits 4A smaller than the slits 4A, that is, the claws 5a.
Hard garbage such as cans, bottles, and plastic bottles wider than the slit 4A cannot be passed through the slit 4A only by the 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)).

[0113] The bag 78 filled with such garbage is 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, and 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 the moving portion of the endless conveyor 2, at least each of the claws 5 in the plurality of claw rows on one side (the side orthogonal to the moving direction of the claw 5) near the input chute 69, In the positional relationship between the two nails 5 closest to each other, the nail 5 located forward in the moving direction of the nail 5 becomes the nail 5 of the nail row on one side, and the nail 5 located behind is the other nail. Since the bags 78 are arranged so as to become the nails 5 of the side row of nails, the bags 78 that have come off from the nails 5 with incompletely broken bags are likely to fall downward along the inclination of the plate 3, The claw 5 is immediately caught by the claw 5 of the claw row on the other side located on the rear side, and jumps up against the claw 5.

The bag 78 caught on the claw 5 on the other side is
The center of gravity moves to the other side by being supported by the claws 5. In addition, the bag 78 that jumps is a
Since they are arranged diagonally downward on the other side, when jumping, the plurality of claws 5 arranged diagonally below
, A component force of the reaction of the collision is applied to the other side. Therefore, there is a strong tendency that the direction of the jump is on the other side. As described above, the bag 78 is moved to the other side and does not stay in the input chute 69 by being repeatedly caught or hit by the claw 5 located at the rear side, and is provided in this direction. By the action of the claw 5 and the blocking plate 4, the bag is repeatedly broken.

At this time, as in the present embodiment, if the bulky material discharge port 70 is provided on the other side of the moving portion of the endless conveyor 2, the bulky material other than the bag 78 filled with dust is mixed. Even when inserted, the closest nails 5 are arranged diagonally downward on the other side, so that the plurality of claws 5 arranged diagonally downward repeatedly raise the other claws 5 upward, It is carried to the part side and reaches the bulky material discharge port 70.

[0119] Therefore, since the bulky material is discharged without stagnation, the bag-breaking action is not hindered by the bulky material, and the treatment can be performed smoothly. Here, in the positional relationship between the two closest claws 5, each of the claws 5 in all the claw rows is arranged such that the claw 5 positioned forward with respect to the moving direction of the claw 5 has the claw 5 on one side. When the nails 5 are arranged such that the nails 5 located on the rear side become the nails 5 in the nail row on the other side, the bulky material carried by the nails 5 becomes the bulky material outlet 70.
Move to hit the body casing 1 on the side,
There is a danger that it will not easily fall into the bulky material discharge port 70 and stay there, and there is a risk that large bottles such as one-shoulder bottles may be broken by hitting the main casing 1 as described above. is there.

In this embodiment, the pawls 5 of several pawl rows on the other side of the endless conveyor 2 (on the side of the bulky material outlet 70) have a positional relationship between the two pawls 5 which are closest to each other. It is not arranged as described above, and the number of nail rows is smaller than the number of nail rows arranged as described above, and since it is a random arrangement, it is possible to prevent the above problem from occurring. be able to.

Unlike the present embodiment, in the case where an opening is provided in the side wall of the main body casing 1 on the other side of the moving portion of the endless conveyor 2 to form the bulky material outlet 70,
The random arrangement as described above is not necessary, and each of the claws 5 in all the nail rows is replaced by the claw 5 positioned forward in the moving direction of the claw 5 in the positional relationship between the two closest claws 5. The nails 5 may be arranged so that the nails 5 of the nail row on one side and the nails 5 located on the rear side become the nails 5 of the nail row on the other side.

Further, as shown in FIG. 13, the virtual line L connecting the nails 5 closest to each other forms an angle θ1 in the range of 110 to 150 degrees with respect to the moving direction A of the nail 5. The arrangement of the claws 5 closest to each other plays an effect as described above, that is, the bag 78 is put into the input chute 69.
The function of repeatedly receiving the bag breaking action by the action of the claw 5 and the blocking plate 4 and the function of discharging the bulky material without being retained are exhibited more effectively.

In addition, in FIG. 13, the distance between the two closest claws 5 described above, that is, for example, in FIG. 13, the slit in the row A and the slit in the row B, the slit in the row B and the slit in the row C, It is good to set the interval of 100 to 200 mm, preferably 120 to 180 mm.

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, 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 is movable in a direction in which the claw 5 is inserted into the slit 3A. Then, the hard material caught between the dam plate 4 and the claw 5 is removed, and the hard material falls on the plate 3 by the action of gravity, and is discharged from the dust discharge chute 3b to the discharge conveyor 74.
And discharged from the apparatus from here.

Therefore, the processing can be continuously performed without damaging the claws 5 and the dam plate 4. The operation of removing the hard object will be described with reference to FIG.

As shown in FIG. 17A, the claw 5 in a state of rising toward the hard object 79 larger than the slit 4A advances. As shown in FIG. 3B, when the hard material 79 bites between the claw 5 and the dam plate 4, the claw 5 rotates in the direction opposite to the traveling direction against the elastic force of the elastic member. And fall.

As shown in FIG. 17C, the hard material 79 escapes from between the claw 5 and the dam plate 4 by the rotation of the claw 5. Therefore, as shown in FIG. 4D, the claw 5 advances through the slit 4A of the dam plate 4.

By this operation, the hard material 79 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. When a large object (hard object) or the like larger than the gap 61 (discharge portion) is input, the large object is prevented from being caught by the above-described biting prevention action.

Here, the claw 5 hooks the blocking plate 4
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 horizontally in 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 toward the bag chute 71 by the rotation of the branch roller 67, and the bag 78 falls to a position near the boundary between the bag chute 17 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 position of the bag falling prevention guide 63 on the side of the lower curved portion 64C of each thin plate member 64 which is separated from the moving portion of the claw 5, the bag 78 is clogged between the adjacent thin plate members 64. In some cases, 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 in the upper moving section of the endless conveyor 2 to cause the small chute 7 to move.
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 parts 8 directly falls toward the lower moving part of the endless conveyor 2, Other parts,
The small piece guide 73 is dropped on the upper surface of the small piece guide 73 and received there.
3 While sliding on the upper surface, it falls toward the lower moving part 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 small piece 80 that has fallen down 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 from the slat 18 removing portion between the upper moving portion and the lower moving portion of the endless conveyor 2 partially drops directly toward the slat 18 removing portion of the lower moving portion. Then, the other part is dropped and received on the upper surface of the small-piece guide 73, and slides on the upper surface of the small-piece guide 73, falls toward the slat 18 removing part of the lower moving part, and finally reaches the small-piece chute 72.

As described above, the bag 78 filled with garbage is provided.
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 garbage comes out of the bag 78 (tearing action). Of the bags subjected to such tearing action,
Regardless of the bag that has been completely torn and has been torn, or a bag in which garbage remains during the tearing action, a part of the bag passes through the slit 4A of the baffle plate 4 and the remaining portion is the baffle plate 4 When the slit 4A does not pass through the slit 4A, the slit 4A may be caught on the end (distal end) side opposite to the portion where the claws 5 pass (base end).

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

For example, 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 that has fallen off falls on the plate 3, and the dropped bag is again 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) opposite to the portion 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 which has already been clogged at the tip end side is opened by the bag which is newly packed toward the tip end side opposite to the portion of the slit 4A through which the claw 5 passes. In the operation of being pushed out toward the bent portion, for example, a configuration in which the claw 5 has an elastic member and is configured to be capable of swinging or falling in the opposite direction to the moving direction according to the resistance applied to the toe portion thereof is not 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 in accordance with the compression pressure, but the slit width is formed so as to gradually increase toward the tip. 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 position of the bag crossing in the slit width direction at a position near the front end portion opposite to the passing portion of the claw 5 of A and facing the back surface corresponding to the back side of the blocking surface of the blocking plate 4 at a predetermined interval. Since the weir 57 for preventing the sneaking is provided, even if the part where the garbage of the bag remains tries to sneak around the open part of the tip of the dam plate 4 of the claw 5, the sneaking is performed by the weir 57. Movement is blocked.

Even in this blocked state, the claw 5 passes through the slit 4A with the bag pulled off or with the bag removed.
Eventually, the bag falls. Further, in the present embodiment, since the dam plate 4 and the plate 3 are integrally formed, no biting occurs at this portion.

Further, in the present embodiment, the nail 5
Attaching the endless conveyor 2 to the upper side of the slat 18 along its moving part facilitates the maintenance of the pawl 5.

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 string enters the slit 3A of the plate 3 and gets caught on the mounting seat 19 of the claw 5, the string easily slips out of the mounting seat 19. ,
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 device of the first embodiment 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 A range of 45 ° to 60 ° is preferable.

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.

If the angle is larger than the angle in the above range, when a solid is caught between the dam 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.

Further, the thickness b of the nail is preferably as thin as the strength of the nail allows, but it is practically about 3 mm to 10 mm, for example. Next, the relationship between the dam plate 4 and the plate 3 (endless conveyor 2) will be described.

As shown in FIGS. 1 and 7, for example, as in this embodiment, the dam plate 4 is formed integrally and continuously with the plate 3, and the tip of the plate 3 is gradually curved and the tip of the claw 5 is formed. Those formed so as to be located outside the orbit are imaginary perpendicular to the orbit of the tip of the claw 5 within the movement range of the claw 5 (between the orbit of the claw tip and the dam plate 4 or the plate 3). The angle between the line and the tangent to the blocking plate 4 is always equal to or greater than zero degrees (so that the outer side of the tangent to the blocking plate 4 is above the imaginary line perpendicular to the trajectory of the tip of the claw 5. ), It is preferable that the dam plate 4 is gently curved. Accordingly, even when foreign matter which is pushed by the claws 5 such as an electric wire cord, an electric cable, a hanger, and an umbrella and is deformed and easily clogs the slit 4A is bitten, the blocking plate 4 is gently curved. Even if pressed, a foreign component is generated against the foreign matter, and the foreign matter is automatically removed. The effect of this is that the nail 5
It has an elastic member such as the torsion coil spring 22 and is more effectively combined with the function and effect of being 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 5. Be demonstrated.

When the partition between the dam plate 4 and the plate 3 (endless conveyor 2) is clear as shown in FIGS. 14 to 17 described later, the dam plate 4 and the plate 3 (endless conveyor 2) are connected. It is preferable that the angle φ (see FIG. 17) is 60 to 120 degrees, preferably 80 to 100 degrees.

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 effective value c of the nail 5 varies depending on the size of the bag 78. When there is a width in the size of the bag 78 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 so that only the claws 5 and the broken bag 78 pass through, and the slit width d 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 78 to pass through the slit 4A of the dam plate 4, and the smooth discharge of the broken bag 78 is not performed. This leads to a reduction in bag efficiency. On the other hand, if the slit width d is too wide, dust will pass through the slit 4A together with the bag 78, and an incomplete bag will be generated with the dust still in the bag 78.

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 will be described.
The space portion (discharge portion) 61 between the dust discharge chute 3b and the cutout chute 60 will be described. The above-mentioned interval portion 61
The smaller the size of the garbage to be treated is as small as possible within the range in which the garbage can be discharged, the less the small bag containing the garbage is discharged without being caught on the nail 5.

When the object is garbage, such as cans, bottles, and plastic bottles, the above-mentioned interval f is 80 mm to 20 mm.
0 mm, preferably 120 mm to 160 mm. In the above embodiment, the endless conveyor 2
Although the example in which only the plurality of claws 5 are provided is shown in the above, the present invention is not limited to this, and a blade capable of cutting a bag may be provided instead of some of the plurality of claws 5.

Further, in the above embodiment, the claw 5 and the coil spring 22 as the elastic member are separated from each other, but the claw and the coil spring as the elastic member are formed of the same wire and are integrated. May be used. 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, the waste discharge conveyor 74 does not need to be installed independently, and the conveyor for transferring the waste to the next process is extended to the lower part of the discharge part so that the waste discharge conveyor 74 is also used as the waste discharge conveyor 74. May be.

Next, a second embodiment of the present invention will be described with reference to FIG.

Claw 5 and dam plate 4 around upper end
With the action described above, the bag-breaking ability is at least twice as large as that of the bag-breaking device in which the endless conveyor 2 is arranged on one side.

The functions and effects of the third embodiment other than those described above are the same as those of the first embodiment.
Next, a fourth embodiment of the present invention will be described with reference to FIG.

The bag breaking device of this embodiment is basically the same as the bag breaking device of the first to third embodiments, except that a plate having a slit through which a claw can pass is endless. The point is that it is not arranged along the moving part on the upper side of the conveyor 2.

That is, in this embodiment, at least the upper moving portion between the lower end portion and the upper end portion has a substantially continuous surface, and the endless conveyor has a plurality of claws 5 arranged along the moving portion. 2 is disposed such that the moving direction of the upper moving part is located at a higher position, and one end of the dam plate 4 is in contact with or close to the surface of the upper moving part of the endless conveyor 2. The second embodiment differs from the first embodiment in that the other end is provided outside the upper moving unit.

[0177] In this embodiment, the baffle plate 4 is provided as shown in FIG.
As shown in FIG. 7, it is composed of a large number of rectangular blocking plate constituent members 51 which are arranged side by side at predetermined intervals (intervals serving as slits) in the horizontal direction and are connected to each other.

Further, there is provided a connection support member for connecting and fixingly supporting the respective blocking plate constituent members 51 while maintaining a predetermined interval between the respective blocking plate constituent members 51. The connecting support member is disposed at a position separated from a back surface corresponding to the back side of the blocking surface of each blocking plate constituent member 51, and is connected to a horizontal beam member 52 (first supporting portion) fixed to the wall of the main body casing 1. A plurality of support feet 53 (second support portions) extending from the horizontal rail member 52 toward the blocking surfaces of the respective blocking plate constituent members 51 and fixed to the blocking surfaces. Is done.

In this case, one end of each support leg 53 is fixed by welding or the like to a mounting plate 55 fixed to the upper surface of each blocking plate member 51 by a bolt 54 or the like, and stands upright. They are arranged side by side.

The support legs 53 arranged in parallel
Is fixed to the side surface of the horizontal rail member 52 by a bolt 56 or the like. Here, in the present embodiment, the distance between the slit 4A of the blocking plate 4, that is, the distance between the adjacent blocking plate constituent members 51 is from the end of the claw 5 on the side of the passing portion to the end opposite to the end. It is formed so that the slit width gradually increases toward the part (tip part).

In this case, the inner surfaces of the adjacent dam plate constituent members 51 are cut obliquely and set to the above slit width. The slit 4A of the blocking plate 4 is located in the vicinity of the tip of the claw 5 on the side opposite to the passing portion (passing portion) of the claw 5, and behind the blocking surface (the lower surface in FIG. 17) of the blocking plate 4. A weir 57 is provided at a position facing the rear surface (the upper surface in FIG. 17) with a predetermined interval therebetween to prevent the bag from running around in the slit width direction.

Also in this embodiment, since the discharge conveyor 74 is used for collecting and discharging the small pieces 80, the size of the apparatus can be reduced as compared with the first embodiment.

As a countermeasure against biting of a hard object or the like between the dam plate 4 and the endless conveyor 2, for example, the horizontal beam member 52 is swingably attached to the wall of the main body casing 1 via a hinge or the like. A swinging means such as a spring is interposed between the wall of the main body casing 1 and the support foot 53 so that when a force greater than a predetermined value is applied to the blocking plate 4, the blocking plate 4 moves backward in the moving direction of the claw 5. May be configured. This countermeasure is
It is also effective when the plate 3 and the dam plate 4 are formed separately in the embodiment.

The functions and effects of the fourth embodiment other than those described above are the same as the functions and effects described in the first embodiment. In the fourth embodiment, one end of the dam plate 4 is in contact with or close to the surface of the upper moving unit of the endless conveyor 2 and the other end is located outside the upper moving unit. It is characterized in that it is provided, and one endless conveyor 2 having a plurality of claws 5 arranged along the moving part is arranged. However, as a bag breaking device having the above characteristics, at least a lower end part and A substantially continuous surface is formed in the upper moving portion between the upper moving portion and the two endless conveyors 2 each having a plurality of claws arranged along the moving portion. As the tip is located at a high position, and the lower ends of each are approached at a predetermined interval, and the upper ends are opposed to each other so as to be separated most, that is, both endless conveyors,
A configuration in which the components are installed so as to face each other so as to form a substantially V-shape may be adopted (fifth embodiment).

According to the fifth embodiment, the bag breaking device in which the endless conveyors are arranged on both sides is provided by the tearing action of the claw of the endless conveyor on both sides around the lower end and the action of the claw and the dam plate around the upper end. As compared with a bag breaking device in which the endless conveyor 2 is disposed on one side, the bag breaking processing ability is more than doubled.

In each of the above embodiments, the claw 5 can pass through corresponding to the slit 3A of the plate 3,
In addition, the slit 4A having both open ends is provided, but a slit having a closed end may be provided.

As described above, according to the bag breaking apparatus according to any one of the first to sixth aspects of the present invention, the bag is incompletely broken by devising the arrangement of the claws on the endless conveyor. The bag that has come off the nails is moved to the other side of the moving part, such as a conveyor belt or conveyor chain, so that the bag that has been thrown into one side with the throwing part does not stay and the other side It is possible to repeatedly receive the bag breaking action by the action of the claw and the blocking plate provided in the direction of the part, so that one side of the moving part is at the same height as the other side without the inclined endless conveyor being arranged. Can be arranged substantially horizontally.

As a result, for example, the drive shaft, bearings, sprockets, etc., which constitute the drive unit of the endless conveyor, are naturally arranged substantially horizontally. In addition, they have excellent durability and are advantageous in terms of maintenance of the apparatus as compared with the case where the endless conveyor is arranged at an angle.

In this case, according to the second aspect of the present invention, the bulky material other than the bag filled with dust is provided by providing the bulky material discharging portion on the other side of the moving portion of the endless conveyor. Can be sent out to the outlet even if is mixed in, and the bulky material is discharged without stagnation,
The bag can be smoothly processed without the bag breaking action being hindered by the bulky material.

In particular, according to the bag breaking device of the third aspect of the present invention, the plate having the slit through which the pawl can pass is moved along the moving part such as the conveyor belt or the conveyor chain on the upper side of the endless conveyor. Provided above, a blocking plate is fixed to or integrally formed with the plate,
In addition, since the slit is formed so as to be continuous with the slit of the plate, hard waste such as a can or the like does not get caught between the plate and the dam plate, and can be processed smoothly. In addition, small debris or the like that has come out of the bag slides down on the plate surface and goes to the discharge portion, so that the broken bag and the contents can be accurately separated.

Similarly, according to the bag breaking device of the fourth aspect of the present invention, since the endless conveyor forms a substantially continuous surface at least in the upper moving portion between the lower end and the upper end. Small garbage that has come out of the bag slides down on a substantially continuous surface of the endless conveyor and goes to the discharge section,
The broken bag and the contents can be accurately separated.

Furthermore, according to the invention of claim 5, two endless conveyors are provided, and the two endless conveyors are
Because each lower end part approaches each other at a predetermined interval, the upper end parts are opposed to each other so as to be most separated, and the claw and the dam plate are provided for each endless conveyor. The endless conveyor is disposed on one side according to the invention according to claims 1 to 4, by the tearing action of the claw of the endless conveyor on both sides around the lower end and the action of the claw and the dam plate around the upper end. As compared with a bag breaking device that breaks a bag by the action of a plate, the bag breaking ability is more than doubled.

According to the sixth aspect of the present invention, the imaginary line connecting the closest claws is formed at an angle of 110 to 150 degrees with respect to the moving direction of the claws.
The arrangement of the nails closest to each other, for example, the conveying action such as the conveying blade of a screw conveyor can be more effectively exerted.
