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 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.

For example, in Japanese Unexamined Patent Publication No. Hei 6-170267, as shown in FIGS. 16A and 16B, the sliding arm 204 provided on the upper portion of the main body 201 having the garbage bag inlet 202 on the upper side is moved upward and downward. A required number of plate-shaped blades (fixed blades) 205 are attached to the side ends in a hanging manner in parallel with each other so that the plate-shaped blades 205 face the garbage bag transfer unit 206, and the plate-shaped blades 205 Endless rotary body 2 having plate-like blades (moving blades) 208 that can pass between blades (fixed blades) 205 attached with a phase that forms a receding angle with respect to a required number of traveling directions.
07 has been proposed.

[0005]

However, such a conventional bag breaking device has the following problems.

That is, the fixed blade 205 is attached to the swing-side end of the swing arm 204 disposed in the upper part of the main body so as to hang down, and thus the fixed blade 205 extends from the top to the bottom. In the configuration, the positional relationship between the fixed blade 205 and the movable blade 208 with respect to the size of the garbage bag is as follows.
It is an important issue to tear the garbage bag smoothly.

For example, in order for a small garbage bag to hit the fixed blade 205, the fixed blade is extended long between the movable blades, and the tip of the fixed blade is disposed above the endless rotary body. However, in such a case, there is a possibility that a large garbage bag is hindered by the fixed blade 205 and the transfer is not performed smoothly, and there is a possibility that the garbage bag is clogged.

To avoid this, it is necessary to shorten the fixed blade 205 so that the tip of the fixed blade 205 is far away from the upper surface of the plate portion 206a disposed above the endless rotating body. This time the small garbage bag is fixed blade 205
And the garbage bag may pass through without being torn.

For this reason, it is difficult to obtain a smooth transporting action and a tearing action in response to garbage bags of various sizes, and the garbage bags to be treated have a specified size. There is a disadvantage that the usability is poor.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned technical problems. In a bag breaking apparatus based on a configuration in which a bag is torn by a movable claw and a fixed blade, regardless of the size of the bag, Another object of the present invention is to ensure that the tearing action of the bag is always exerted.

The moving claw has a slit through which the moving claw can pass, and a dam plate having a tip located outside a tip orbit of the moving claw passing through the slit is provided.

According to a sixth aspect of the present invention, in the bag breaking device according to any one of the first to fifth aspects, the endless conveyor is arranged such that a moving direction destination of an upper moving portion thereof is located at a higher position. Preferably, the upper moving part is provided to be inclined, and the plate is provided to be inclined above the endless conveyor along the inclination of the upper moving part of the endless conveyor.

According to a seventh aspect of the present invention, in the bag breaking apparatus according to the sixth aspect, the fixed blade is provided obliquely with respect to a moving direction of a moving portion of the endless conveyor. I do.

According to an eighth aspect of the present invention, in the bag breaking apparatus according to the seventh aspect, one side of the moving portion of the endless conveyor (one side in a direction orthogonal to the moving direction of the moving portion of the endless conveyor). ), The fixed blades are inclined such that the one side of the moving part of the endless conveyor is at a high position and the other side of the moving part is at a low position. It is characterized by being provided.

In the invention according to claims 1 to 8,
As the endless conveyor, a conveyor having a continuous surface formed in a moving part such as a conveyor belt or a conveyor chain, for example, a flat top conveyor, an apron conveyor, a pan conveyor or the like provided with a moving claw on a chain conveyor or a belt conveyor. However, it is not necessary that a continuous surface is formed in the moving part,
A member provided with a moving claw on a member moved by a chain may be used.

Further, in the inventions according to the first to eighth aspects, the "moving claw" means a projection, a hook, or the like having a square shape, a plate shape, a linear shape, and the like, for example, a linear shape such as a piano wire or a steel wire. It may be a member, and it is preferable that the tip is inclined in the moving direction of the claw or has a hook shape.

The point is that any material can be used as long as the tip cuts 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.

Further, in the invention according to claims 1 to 8,
The "fixed blade" only needs to have an action of hooking the packaging material by cutting the tip into at least a part of the packaging material such as a bag. It is preferable that the blade has a cutting action of cutting the packaging material, but the cutting action of the blade is not necessarily required. Therefore, the blade portion in the present invention includes a blade having a sharp blade, a blade having a shape such as a protrusion or a hook that can be hooked with a packaging material without a blade, and a bag or the like. Anything can be used as long as the tip bites into part of the packaging material and has the effect of hooking the packaging material.
The “fixed blade” also includes the concept of “fixed claw”.

Further, in the invention according to claim 5, the "dam plate" does not have to be a product in which an independent part as an article is fixed to a plate close to or in contact with a plate by welding, bolts, nuts or the like. It may be formed integrally with the above. 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 passing through the slit. Therefore, the "dam plate"
In the present specification, the term includes the concept of “plate dam portion”, and is the concept interpreted in the broadest sense.

The operation of the present invention will be described. Claim 1
In the bag breaking device described above, for example, a packaging material (hereinafter simply referred to as a bag) such as a plastic bag containing garbage (cans, bottles, plastic bottles, kitchen garbage, etc.) is caught by a moving claw, and the upper surface of the plate is It moves according to the movement of the moving claw while being dragged. When the bag that is moved by being hooked by the moving claw passes through the position of the fixed blade provided on the upper surface of the plate, the bag is moved by the moving claw in a state in which the bag is restrained from moving by the fixed blade. The bag restrained by the blade is torn as the moving claw moves.

Even if the bag comes off the moving claw, it is caught by any one of the moving claws moving one after another and moves forward, and receives the above-mentioned tearing action of the fixed blade and the moving claw. Then, the broken bag is transported by the moving claw to the end of the moving claw on the plate in the moving direction, and is discharged out of the apparatus.

According to the second aspect of the present invention, since the upper portion of the fixed blade protrudes from the lower portion of the blade,
When the fixed blade hooks the bag and tears the bag with the moving claw, the floating of the bag is prevented, the fixed blade bites into the bag, and the bag is more reliably broken.

In the invention according to claim 3, the moving claw is
When a rigid object is caught between the movable claw and the fixed blade as a result of having an elastic member and being configured to be capable of swinging or falling in the opposite direction to the movement direction according to the resistance applied to the toe portion thereof When a predetermined force or more acts on the moving claw, the moving claw moves in the direction opposite to the moving direction, thereby removing the biting hard object. Further, even when a bulky object (hard material) or the like is thrown in, the bite of the bulky object is prevented by the above-described biting prevention action.

As a result, breakage of dust and the like can be prevented, and an effect of not damaging devices such as the movable claw and the fixed blade can be obtained. In the invention according to claim 4, since a plurality of fixed blades are provided at intervals along the slit direction, the bag caught by the moving claw further moves after the tearing action by the fixed blade and the moving claw. It is hooked on and moves forward, receives the above-mentioned tearing action in a state where the movement is suppressed by the fixed blade located in front, and the above-mentioned tearing action is repeatedly performed,
Break the bag more reliably.

[0029] In the bag breaking device according to the fifth aspect, the bag tries to pass through the slit of the dam plate while being caught on the moving claw. What can pass through the slit of the baffle plate is smaller than the slit width, that is, only nails and soft things such as bags caught on it, hard trash etc. larger than the slit width cannot pass through the slit .

Therefore, the bag in which the dust remains even after being subjected to the tearing action by the moving claw and the fixed blade is prevented from passing through the slit, while the bag caught by the claw is torn with the movement of the claw. It is.

The bag with the garbage left is prevented 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 by repeating such an operation several times, the bag becomes When torn, the trash goes out of the bag (tearing action). The bag from which the garbage has completely come out passes through the dam plate while being caught by the claws, is drawn into the lower moving section of the endless conveyor, and falls by the action of gravity, for example, to a discharge chute.

[0032] In the invention according to claim 6, the endless conveyor is provided such that the upper moving part is inclined so that the moving direction destination of the upper moving part is located at a higher position, and the plate is provided with an endless conveyor. Since it is provided to be inclined above the endless conveyor along the inclination of the moving part on the upper side of the conveyor, the debris coming out of the bag is subjected to the tearing action of the bag by the fixed blade and the moving claw, and the dust coming out of the bag is disposed on the lower side of the plate. The bag which has fallen in the direction and is caught by the moving claw is scraped up by the moving claw in the direction of the high side of the plate, and the dirt and the bag are separated and collected on the low side and the high side of the plate.

Further, even if there is a bag which is not broken and comes off from the moving claw, the bag falls on the plate, and the dropped bag is hooked again by the moving claw, and the bag is formed by the fixed blade and the moving claw. Is subject to tearing action. This enables stable and continuous bag breaking operation.

In the invention according to the seventh aspect, the refuse dropped from the high side of the plate may collide with the refuse or bag at the lower end of the plate, and particularly when the bottles collide, they may be damaged. However, dust falling from the high side of the plate collides with the inclined fixed blade provided on the plate, collides with the side wall of the fixed blade, the falling speed is reduced, and the impact at the time of collision between bottles Is relieved. Therefore, the fixed blade inclined obliquely has an effect of preventing breakage of a bottle or the like.

[0035] In the invention according to claim 8, the bag dropped from the high side of the plate, particularly, the bag dropped down along the inclination of the plate with the incompletely broken bag coming off the moving claw or inside the bag. In the same way as the smaller bag, the bag that fell, the garbage that came out of the bag, and the bulky material (hard material such as a bottle) fall on the inclined fixed blade provided on the plate while falling along the plate. After the collision and deceleration, the installation direction of the fixed blade is such that the side of one side of the endless conveyor moving section where the bag charging section is located is at a high position and the side of the other side of the endless conveyor moving section is at a low level. Because of the inclined direction, many of them fall to the other side of the endless conveyor moving part, and the dropped bag is again caught by the moving claw provided on the other side, and the fixed blade is The bag is torn by the moving claw. Thus, the bag moves to the other side of the endless conveyor moving section and does not stay in the charging section.

Even when a bulky object or the like is thrown in, it is repeatedly moved up and down by the upward movement of the moving claw, the falling of the plate from the high side, and the collision with the fixed blade.
It is sent to the other side of the endless conveyor moving section. Therefore, for example, if a large-size material discharge port is provided on the other side of the endless conveyor moving unit, the large-size material discharge port is discharged outside the apparatus.

[0037]

Embodiments of the present invention will be described below with reference to the drawings. The embodiments described below are:
This is an example in which the bag breaking device of the present invention is applied to a recycling facility for separately collected garbage.

FIG. 1 is a principle diagram for explaining the basic structure of the bag breaking device of the present invention. In this figure,
The bag breaking device includes an endless conveyor 81, a plate 82, and a dam plate 108.

The endless conveyor 81 has a plurality of moving claws 83 having toes directed in the moving direction of the moving section outside the moving section. Further, the plate 82 is provided at a plurality of slits 84 through which the moving claw 83 can pass, and at an upper surface position of the plate 82 beside each slit 84, and is directed in a direction opposite to a moving direction of the moving portion of the endless conveyor 81. And a plurality of fixed blades 85 each having a blade portion. The fixed blades 85 are provided horizontally above the endless conveyor 81 along a moving portion above the endless conveyor 81.

The blocking plate 108 is formed integrally and continuously with the plate 82, and is formed such that its tip is located outside the tip orbit of the moving claw 5 (in a direction away from the moving portion of the endless conveyor 81). Have been. In other words, the blocking plate 108 has its base end connected to the plate 82,
The distal end is horizontally extended further forward than the end of the endless conveyor 81, and is disposed so as to be located in a direction away from the upper moving portion of the endless conveyor 81, and moves in accordance with the slit 84 of the plate 82. Slits 109 are provided through which the claws 83 can pass and both ends are open.

Here, in the present embodiment, the plate 8
2 comprises a plurality of elongated plate-shaped plate components 82A which are arranged side by side in a lateral direction at a predetermined interval forming a slit 84, and
Is composed of a plurality of elongated plate-shaped damming plate constituent members 108A which are arranged side by side in the horizontal direction at predetermined intervals forming the slit 109, and one end of which is fixed to the plate constituent member 82A. Is done.

In this case, the plate constituent member 82A and the dam plate constituent member 108A are integrally formed. In other words, the distal end of the blocking plate constituent member 108A, which is the end of each plate constituent member 82A, is formed so as to be located outside the distal end trajectory of the movable claw 83. That is, the respective plate constituent members 82A are connected to each other while maintaining a predetermined distance between the plate constituent members 82A and a predetermined distance between the respective dam constituent members 108A.

In other words, in other words, a slit through which the moving claw 83 passes is formed from the plate 82, the slit is opened at the tip, and the tip of the plate 82 is located outside the tip orbit of the moving claw 83. It is formed as follows.

In this case, the blocking plate is fixed to or integral with the plate 82, has a slit connected to the slit 84 of the plate 82 and through which the moving claw 83 can pass, and the moving claw passing through the slit. It is sufficient that the distal end portion is located outside the distal end track of 83, and as shown in FIG. 1, may not be disposed horizontally, but may be disposed curved upward and It may be arranged to be bent upward so as to have a predetermined angle with the plate 82.

Here, in the present embodiment, the dam plate 1
08 slit 109, that is, the interval between adjacent dam plate constituent members 108A, is such that the slit width gradually increases toward the end of the moving claw 83 on the side opposite to the passing portion side end (passing portion). Formed.

In this case, the adjacent blocking plate member 108
The inner surface of A is cut obliquely and set to the slit width. As described above, the plate constituent members 82A on which the blocking plate constituent members 108A are integrally formed are arranged horizontally in a direction orthogonal to the longitudinal direction thereof, and the other ends of the plate constituent members 82A are separated on both sides. The two support feet 86, 87 are fixedly attached to the upper surface of one of the support feet 86 by screws 88 or the like.

The other support leg 87 is composed of a support base 87A and a plurality of support plates 87B fixedly mounted in parallel on the upper surface of the support base 87A at a predetermined interval. One end is fixedly attached to the upper surface of each support plate 87B by screws 89 or the like.

Note that one end of the plate 82 (on the side of the blocking plate 108) serves as a discharge portion, and the other end serves as a bag charging portion. The endless conveyor 81 is disposed horizontally, for example, and rotationally drives a drive shaft 90 by a motor or the like, and this rotational drive is transmitted to a drive sprocket (not shown) attached to both ends of the drive shaft 90, and the non-drive shaft 9
It is configured to be attached to both ends and transmitted to a non-drive sprocket that is connected to the drive sprocket via a chain.

The endless conveyor 81 has a structure in which moving claws 83 are provided at specific locations on a large number of long plate-like slats 81A constituting a moving portion, and one side of each slat 81A is not shown. And the other side is fixedly attached to the other conveyor chain, whereby a large number of slats 81A are provided between the two conveyor chains.
In this embodiment, the moving part of the endless conveyor is constituted by both conveyor chains and a large number of slats 81A.

A plurality of moving claws 83 are attached to the upper surface of each slat 81A at predetermined intervals along the longitudinal direction of the slat 81A. In this case, three moving claws 83 are attached to one slat 81A corresponding to every other three slits 84 in the plate 82, and one slat 81A adjacent to this one slat 81A has: The moving claw 83 is not attached, and one slat 81A adjacent to the slat 81A to which the moving claw 83 is not attached is provided with every other slit 84 in the plate 82, adjacent to each of the three slits 84. 3 corresponding to the three slits 84
A moving claw 83 is attached.

Thus, the three forms of slat 81A
Are sequentially repeated, and a large number of moving claws 83 are respectively provided.
Are provided. On the other hand, three fixed blades 85 are attached to one plate component 82A of the plate 82, and the three fixed blades 85 are attached to one plate component 82A adjacent to the one plate component 82A. The three fixed blades 85 are attached at positions shifted from the positions by a predetermined length in the longitudinal direction of the plate constituent member 82A.

As described above, the arrangement of the plate forming members 82A in the two forms is sequentially repeated, and the fixed blade 85 is positioned at the upper surface of the plate beside each slit 84.
Are provided at intervals along the direction in which

The fixed blade 85 has a shape in which the upper portion of the blade portion projects forward from the lower portion of the blade portion. In other words, the upper portion of the fixed blade protrudes from the lower portion of the blade, so that the fixed blade 85 can easily bite into the bag.

Next, the operation of the bag breaking device will be described. For example, garbage (cans, bottles, plastic bottles,
A packaging material such as a plastic bag containing kitchen waste (hereinafter simply referred to as a bag) is dropped onto the plate 82 from the loading section.

The bag is hooked on the moving claw 83 which is moved by the driving of the endless conveyor 81, and moves in accordance with the movement of the moving claw 83 while being dragged on the upper surface of the plate 82. The bag, which is thus hooked and moved by the moving claw 83, is moved by the moving claw 83 in a state where the bag is restrained from moving by the fixed blade 85 when passing through the position of the fixed blade 85 provided on the upper surface of the plate 82. Therefore, the bag restrained by the fixed blade 85 is torn with the movement of the moving claw 83. At this time, since the upper portion of the blade portion of the fixed blade 85 has a shape protruding forward from the lower portion of the blade portion, the floating of the bag is prevented, the fixed blade 85 bites into the bag, and the bag is more reliably broken.

After the above-described tearing action of the fixed blade 85 and the moving claw 83, the bag still caught by the moving claw 83 further advances with the movement of the moving claw 83, and is fixed as in this embodiment. Since a plurality of blades 85 are provided at intervals along the direction of the slit 84, the bag is repeatedly subjected to the above-described tearing action in a state where the bag is further prevented from moving by the fixed blade 85 located further forward by the forward movement.

On the other hand, after the tearing action, the moving claw 83
The detached bag is hooked by one of the moving claws 83 that are moving one after another and moves forward, and again receives the above-described tearing action.

Here, as described above, the fixed blade 85
Is provided on the upper surface of the plate 82, and the fixed blade 85 is
In the configuration extending upward from the bottom similarly to 3, the positional relationship between the fixed blade 85 and the moving claw 83 with respect to the size of the bag is particularly important as in the prior art, in order to tear the bag smoothly. There is no problem.

That is, regardless of whether the bag is a small bag or a large bag, the moving blade 83 and the fixed blade 85 can reliably receive the tearing action against the fixed blade 85,
As in the prior art in which the fixed blade is suspended from above, the fixed blade 8
5, the transfer is not hindered, the transfer is performed smoothly, and no clogging of the bag occurs.

For this reason, corresponding to bags of various sizes,
It is easy to get smooth transfer action and tear action,
There is an advantage that the bag to be processed does not have the specified size and is excellent in operability.

In the combination of the moving claw 83 and the fixed blade 85, the blade portion of the fixed blade 85 has no cutting action by the blade and is merely in the form of a claw such as a projection or a hook, and has only an action of hooking the bag. Although it is possible to use a tool (substantially having only the same action as the moving claw 83), it is preferable that the blade has a cutting action by a blade even to some extent than the moving claw 83.

As described above, by making the fixed blade 85 have a slight cutting action by the blade, the bag is more easily caught by the movable claw 83 than the fixed blade 85 after the moving claw 83 and the fixed blade 85 are torn. The repetitive action that the bag is hooked on the moving claw 83 and further advanced in accordance with the movement of the moving claw 83 to perform the above-described tearing action in a state where the movement is suppressed by the fixed blade 85 located in front, It is played more effectively.

The moving claw 83 has an elastic member,
It may be configured to be swingable or upside down in the direction opposite to the moving direction in accordance with the resistance applied to the toe. According to this configuration, when a hard object is caught between the moving claw 83 and the fixed claw 85, if a predetermined force or more acts on the moving claw 83,
When the moving claw 83 moves in the direction opposite to the moving direction, the biting hard object is removed. Further, even when a bulky object (hard material) or the like is thrown in, the bite of the bulky object is prevented by the above-described biting prevention action.

As a result, breakage of dust and the like can be prevented, and an effect of not damaging devices such as the movable claw 83 and the fixed blade 85 can be obtained. Thus, the garbage that has come out of the torn bag is pushed forward by the moving claw 83 itself or the bag caught by the moving claw 83 and advances.

On the other hand, the bag that is still caught by the moving claw 83 that is moving forward is inserted into the slit 1 of the fixed blocking plate 108.
09 through the slit 1 of the dam plate 108
09 can only pass through the slit 109, which is smaller than the width of the slit 109, that is, only a movable claw 83 and a soft object such as a bag hooked on the movable claw 83, such as a can, a bottle, a plastic bottle, and the like wider than the slit 109. Hard dust cannot pass through the slit 109.

Therefore, the moving claw 83 remains with the dust remaining.
Is restrained from passing through the slit 109, and is torn with the movement of the moving claw 83, and the remaining garbage comes out of the bag.

The blocking plate 108 and the moving claw 83
Is formed so that at least the tip of the blocking plate 108 is located outside the tip orbit of the moving claw 83 passing through the slit 109, or is folded outward so as to have a predetermined angle with the plate 82. If it is not erected and bent, it will not be generated, and for example, as shown in FIG.
This tearing action does not occur when the tip of 6a is located inside the tip trajectory of the movable blade 208.

Among the bags subjected to the tearing action by the blocking plate 108 and the moving claw 83, regardless of whether the bag has been completely torn and has been garbage-removed, or the bag in which garbage remains during the tearing-off action, Part of the slit 109 of the blocking plate 108
Through the slit 109 of the blocking plate 108
The moving claw 83 of the slit 109 is not passed through the
May be stuck on the end (tip) side opposite to the passing portion (base end).

When the operation of the bag breaking device is continued, the bag clogged on the tip side is pushed into the bag clogged on the tip side of the slit 109 by the pushing action of the moving claw 83 toward the tip side. When it reaches the open part of the end, it comes off.

In this case, in the present embodiment, the slit 109 gradually moves toward the front end portion (the front end portion beyond the front end of the moving claw 83 passing through the slit 109) opposite to the portion where the moving claw 83 passes. Since the slit is formed so as to have a large width, the passage resistance of the bag when the slit 109 is moved is reduced, and the bag clogged in the slit 109 can be quickly pushed out.

That is, as described above, the bag that has already been clogged toward the distal end side opposite to the portion of the slit 109 through which the moving claw 83 has passed can be opened. In the operation of being pushed out toward the part that has been moved, for example, as described above,
In the case where the elastic member is configured to be able to swing or fall in the direction opposite to the moving direction in accordance with the resistance applied to the distal end portion, the bag clogged in the slit 109 is pushed by the elastic force of the elastic member. Been moved. During this time, the bag is in a compressed state, and when moving through the slit 109, the passage resistance of the bag increases in accordance with the compression force, but the slit width is formed so as to gradually increase toward the distal end portion. Therefore, the passage resistance of the bag when moving through the slit 109 is reduced, and the bag clogged in the slit 109 is quickly pushed out.

The bag from which the dust has completely come out passes through the blocking plate 108 while being caught by the moving claw 83, is drawn into the lower moving portion of the endless conveyor 81, and is actuated by the action of gravity. It falls out and is discharged.

The dust from the bag that has been torn by the fixed blade 85 and the dust that has come out of the bag in which the dust has remained due to the blocking plate 108 are transferred to the discharge portion of the plate 82 at the end of the moving claw 83 in the moving direction. It is discharged outside the device.

FIG. 2 shows a more specific embodiment of the bag breaking device of the present invention. The bag breaking device of this embodiment includes a main body casing 1, an endless conveyor 2, a plate 3,
And a dam plate 4.

The endless conveyor 2 has a track shape in which the inclination becomes steeper as the upper surface goes upward from below and becomes nearly vertical, and a part of the moving portion of the endless conveyor follows the track shape. Conveyor chains 11 and 12 (see FIG. 3) are provided. Therefore, since the endless conveyor 2 has a curved moving portion, a chain guide (not shown) is arranged above and below a conveyor chain described later to guide the chain along the moving portion while bending the chain. I do.

The branch roller 67 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 side by side, and close to the lower curved portion 64C. 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. And
An inlet is provided on one side of the endless conveyor 2. 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 endless conveyor 2.

In this case, the input chute 69 is opened laterally (upward in FIG. 9) of the cutout chute 60. 9 and FIG.
As shown in FIG. 2, a cover 1A forming a part of the main casing 1 extends obliquely downward from the outer surface of the main casing 1 to cover the cutout chute 60 inside, and the other end of the other end of the endless conveyor 2 is provided. It is provided so as to reach the side wall of the main body casing 1 on the side.

On the other side of the endless conveyor 2,

In this case, small pieces such as dust falling from the slit 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 moving 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. 11, 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 bolts 77 or the like. Attach fixedly.

In this case, insertion holes 75A, 76A for the bolt 77 are formed at the same position on both the rubber plate 75 and the iron plate 76, 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.

A screw groove 50A for 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 movable claw 5 and the width of the slit 4A of the dam plate 4 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 onto the upper surface of the rubber plate 75 (FIG. 12A)
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 damage such as cans, bottles, and plastic bottles in the bag is prevented. The bag 78 is hooked by the moving claw 5 from the lower part to the upper part between the slits 3A provided in the plate 3 and is lifted upward according to the movement of the moving claw 5 while being dragged on the upper surface of the plate 3. Be moved.

As described above, the bag 78 that is moved by being hooked on the moving claw 5 is provided with the fixed blade 59 provided on the upper surface of the plate 3.
Is moved by the movable claw 5 in a state where the movement of the movable claw 5 causes the bag 78 to be torn along with the movement of the movable claw 5. . At this time, since the upper portion of the blade portion of the fixed blade 59 has a shape protruding forward from the lower portion of the blade portion, the floating of the bag 78 is prevented, the fixed blade 59 bites into the bag, and the bag is more reliably broken.

After the above-described tearing action of the fixed blade 59 and the moving claw 5, the bag 78 which is still hooked on the moving claw 5 holds the bag 78 after the above-mentioned tearing action of the fixed blade 59 and the moving claw 5.
And further advances as the movable claw 5 moves.

The bag 78 detached from the moving claw 5 is caught by any one of the moving claws 5 moving one after another, and also advances. Also, garbage 78A that has come out of the torn bag 78
Falls through the gap between the adjacent moving claws 5 to the bottom of the inclined plate 3, passes through the gap 61 (discharge section),
The sheet is conveyed to the next processing step by the discharge conveyor 74 disposed below the sheet.

Also in this embodiment, the fixed blade 59 is provided on the upper surface of the plate 3 and the fixed blade 59 extends upward from the bottom similarly to the movable claw 5. The positional relationship between the fixed blade 59 and the moving claw 5 does not cause any particular problem in the smooth tearing of the bag as in the prior art, and the smooth transfer action and the tearing can be performed for bags of various sizes. There is an advantage that the function is easy to obtain, the bag to be processed does not have the specified size, and the operability is excellent.

Also, in the combination of the movable claw 5 and the fixed blade 59, the blade portion of the fixed blade 59 has a claw-like shape such as a protrusion or a hook without a cutting action by the blade, and an action of hooking the bag. The movable claw 5 and the fixed blade 5 may be provided with a cutting action by a blade, which is slightly smaller than that of the movable claw 5.
After the tearing action of 9, it is preferable that the bag is more easily caught by the movable claw 5 than the fixed blade 59, and the bag is caught by the movable claw 5 and further advanced according to the movement of the movable claw 5. .

Thus, the moving claw 5 moving forward keeps the slit 4A of the blocking plate 4 fixed while the bag 78 is hooked.
(See FIG. 12B). Only slits smaller than the width of the slit 4A, that is, only the movable claw 5 and a soft one such as a bag 78 hooked on the movable claw 5 can pass through the slit 4A of the dam plate 4, and cans wider than the slit 4A. Hard trash such as bottles, bottles, plastic bottles, etc. cannot pass through the slit 4A.

Therefore, the bag 78 with the remaining dust is suppressed from passing through the slit 4A, while the bag 78 hooked on the moving claw 5 is torn with the movement of the moving claw 5 (FIG. 12C). (D)).

[0146] The bag 78 with such garbage remains in the slit 4A.
Of the bag 7 caught by the moving claw 5
While repeating the action of 8 being torn by the moving claw 5 several times, the bag 78 with the garbage is torn, and the garbage 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 moving claw 5, and is drawn into the lower moving portion of the endless conveyor 2 by the action of gravity. , Falls into the bag chute 71.

[0148] Garbage 78A from the bag 78 with the garbage remaining
Also fall to the bottom of the plate 3 and are transported by the discharge conveyor 74 to the next processing step. Here, in the present embodiment, the fixed blades 59 are arranged such that the input chute 69 corresponding to one side of the endless conveyor moving unit is at a high position, and the coarse material outlet 70 corresponding to the other side of the endless conveyor moving unit.
Because the side is inclined so that it is low,
A bag 78 dropped from the vicinity of the dam plate 4, particularly a bag 78 that fell off the moving claw 5 and fell down along the slope of the plate 3 with an incompletely broken bag, and a smaller bag contained therein. Similarly, the bag 78 that has dropped in the state, the garbage 78A that has come out of the bag,
Further, a large object (a hard object such as a bottle) larger than the interval portion 61 (discharge portion) is falling along the plate 3,
After colliding with the inclined fixed blade 59 provided on the plate 3 and decelerating, the installation direction of the fixed blade 59 is higher on the input chute 69 side as described above, and the
Since the side is inclined so as to be lower, many of them fall so as to approach the bulky material outlet 70 and the bag 78 does not stay on the charging chute 69 side. The dropped bag 78 is again moved by the moving claw 5 provided on the bulky material outlet 70 side.
And the fixed blade 59, the moving claw 5 and the blocking plate 4 repeatedly cause a bag-breaking action. While being repeatedly moved up and down by falling and colliding with the fixed blade 59, it is fed in a direction approaching the bulky material outlet 70 and discharged from the bulky material outlet 70 out of the apparatus.

On the other hand, the garbage dropped from near the dam plate 4
It may collide with dust or bags on the lower end side of the plate 3, and particularly when the bottles collide with each other, they may be damaged.

The inclined fixed blade 59 provided on the plate 3 has the effect of reducing the falling speed as described above by the collision of the dust falling from the vicinity of the dam plate 4 as described above. This has the effect of reducing the impact at the time of collision between the two and preventing the bottle and the like from being damaged.

Here, the movable claw 5 has an elastic member (torsion coil spring 22), and can be swung or turned upside down in the moving direction according to the resistance applied to the toe 5A. As a result of the configuration, when a hard object is caught between the movable claw 5 and the fixed blade 59, the movable claw 5 moves in a direction in which the movable claw 5 is inserted into the slit 3A when a predetermined force or more acts on the movable claw 5. As a result, the hard object that has been caught is removed, and the hard object falls onto the plate 3 by the action of gravity, reaches the discharge conveyor 74 from the dust discharge chute 3b, and is discharged out of the apparatus.

Further, even when a bulky object (hard material) or the like is thrown in, the bite of the bulky object is prevented by the above-described biting prevention action. As a result, breakage of dust and the like can be prevented, and an effect of not damaging devices such as the movable claw 5 and the fixed blade 59 can be obtained.

Further, in the case of having the blocking plate 4 as in this embodiment, when a hard object is caught between the moving claw 5 protruding from the plate 3 and the blocking plate 4, the moving claw 5 When the force is applied, the movable claw 5 moves in the direction of being inserted into the slit 3A, and the hard material that has caught between the dam plate 4 and the movable claw 5 is removed. , Drops on the plate 3, reaches the discharge conveyor 74 from the dust discharge chute 3b, and is discharged out of the apparatus from here.

Therefore, the processing can be continuously performed without damaging the moving claw 5 and the dam plate 4. The operation of removing the hard material caught between the moving claw 5 and the dam plate 4 will be described with reference to FIG.

As shown in FIG. 17A, the moving claw 5 in a state of rising toward the hard object 79 larger than the slit 4A advances. As shown in FIG. 7B, when the hard object 79 bites between the moving claw 5 and the dam plate 4, the moving claw 5 is opposed to the traveling direction against the elastic force of the elastic member. Rotate and fall.

As shown in FIG. 17C, the movable claw 5 rotates, whereby the hard object 79 escapes from between the movable claw 5 and the dam plate 4. Accordingly, as shown in FIG. 4D, the moving claw 5 advances through the slit 4A of the dam plate 4.

By the above operation, the blocking plate 4 and the moving claw 5
The hard material 79 caught between them can be removed, and processing can be continuously performed without damaging the moving claw 5 and the dam 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 bag 78 caught by the moving claw 5 and passed through the slit 4A of the dam plate 4 is drawn into the lower moving portion of the endless conveyor 2, and the bag chute 71 is acted on by gravity. To fall. However, some bags 78
May not be dropped on the bag chute 71 but may be caught on the moving claw 5.

The bag 7 still caught on the moving claw 5
8 is dragged by the moving claw 5 on the bag drop prevention guide 63, passes through the upper moving portion of the endless conveyor 2, and is drawn into the lower moving portion again, and the bag is moved by the action of gravity. You have the opportunity to fall to the chute 71.

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.

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 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 of the bag drop prevention guide 63 on the side of the lower curved portion 64C of each of the thin plate members 64 which is separated from the moving portion of the movable claw 5, each of the adjacent thin plate members 64 is located.
Although the bag 78 may be clogged in between,
7 is provided near the end of each of the thin plate members 64 of the bag drop prevention guide 63 on the side of the lower curved portion 64 </ b> C, so that each of the thin plate members 64 of the bag fall prevention guide 63 is 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 slide on the slats 18 in the upper moving portion of the endless conveyor 2 and slide the small piece chute 7
2 and the slats 1 of the endless conveyor 2
The small pieces 80 that have 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 drop toward the lower moving part of the endless conveyor 2. Then, the other part is dropped and received on the upper surface of the small-piece guide 73, and falls toward the lower moving part of the endless conveyor 2 while sliding on the upper surface of the small-piece guide 73.

The dropped small pieces 80 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,
Even if the slats 18 of the endless conveyor 2 on which the moving claws 5 are not provided are removed, the small pieces 80 that have 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 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 18 of the lower moving part.
It falls directly to the removal part, and the other part
It is dropped and received on the upper surface, and slides down the upper surface of the small piece guide 73 toward the slat 18 removing section of the lower moving section, and finally reaches the small piece chute 72.

As described above, the moving claw 5 and the fixed blade 59
Even after being subjected to the tearing action of the moving claw 5, the bag 78 with the remaining dust is suppressed from passing through the slit 4 </ b> A of the dam plate 4, and the bag 78 caught on the moving claw 5 is torn with the movement of the moving claw 5 By repeating this action several times,
The bag 78 is torn and the refuse comes out of the bag 78 (tearing action). Of the bags subjected to such a tearing action, the bag which has been completely torn and has been torn away, and the garbage in the middle of the tearing action. Irrespective of the bag in which the slit remains, a part of the bag passes through the slit 4A of the blocking plate 4, and the remaining portion does not pass through the slit 4A of the blocking plate 4.
There is a case where the moving claw 5 of A is hooked on the end (distal end) side opposite to the passing portion (base end).

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

For example, in the case where the plate 3 having the slit 3A through which the moving claw 5 can pass is provided as in the present embodiment, the above-mentioned detached bag falls on the plate 3, and the dropped bag is again It is caught by the moving claw 5 and is carried in the direction of the slit 4A of the dam plate 4, and is subjected to "tearing action", thereby enabling a stable and continuous bag breaking operation.

Further, in the present embodiment, the slit 4A is gradually slit toward a tip portion on the opposite side to the portion where the moving claw 5 passes (the tip portion ahead of the tip of the moving claw 5 passing through the slit 4A). Since the width is formed to be large, the passage resistance of the bag when moving through the slit 4A is reduced, and the bag clogged in the slit 4A can be quickly pushed out.

That is, as described above, the bag which has already been clogged toward the distal end side opposite to the portion where the moving claw 5 of the slit 4A has passed can be opened by the bag which has already been clogged at the distal end side. In the action of being pushed out toward the set portion, for example, the moving claw 5 has an elastic member and is configured to be able to swing or fall in the direction opposite to the moving direction according to the resistance applied to the toe. In the thing, slit 4A
Is moved by the elastic force of the elastic member. During this time, the bag is in a compressed state and the slit 4A
When passing through the slit 4A, the passage resistance of the bag increases in accordance with the compression pressure, but since the slit width is gradually increased toward the tip end, the passage of the bag when moving through the slit 4A is performed. The resistance is reduced, and the bag packed in the slit 4A is quickly pushed out.

In this embodiment, the slit 4
A bag that crosses in the slit width direction at a position in the vicinity of the front end portion opposite to the passing portion of the moving 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 sneaking in is provided, even when the remaining portion of the bag is hooked by the moving claw 5 and the sneaking around the open part of the end of the dam plate 4 is attempted, The weir 57 prevents the wraparound movement.

Even in this blocked state, the moving claw 5 tears the bag or passes through the slit 4A with the bag removed, and 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 moving claw 5
Is attached to the upper side of the slat 18 along the moving part of the endless conveyor 2, so that the maintenance of the moving claw 5 is facilitated.

The side wall of the mounting seat 19 of the moving claw 5 shown in the embodiment of FIGS. 3 to 6 is formed in a substantially trapezoidal shape having an inclined surface 19A which becomes lower as the endless conveyor 2 moves in the moving direction. As a result, for example, in the case of a string having a string, such as a water bottle, as the input foreign matter, the main body of the water bottle is blocked by the dam plate 4, and the string enters the slit 3A of the plate 3 and moves. 5 mounting seats 1
Even when it is hooked on the cord 9, the cord is easy to slip out of the mounting seat 19, so that the risk of an emergency stop of the device can be avoided as much as possible.

The moving claw 5 shown in the embodiment of FIG.
Is attached to the lower side of the slat 18 which is the moving part of the endless conveyor 2, so that the slat 18 which is the moving part
Unnecessary unevenness can be avoided on the upper side of the slat 18 as much as possible, and there is no possibility that dust coming out of the bag that has passed through the slit of the plate as in the case where the moving 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 second embodiment having the above configuration will be described with reference to FIG. The moving claw 5 may be linear, but in this embodiment, the toe 5A of the moving claw 5 is bent in the moving direction of the moving claw 5, and the bending angle θ is 30 ° to 30 °.
80 °, preferably in the range of 45 ° to 60 °.

When the bending angle θ approaches 60 °,
Since the moving claws 5 can easily hook the bag 78, the bag breaking efficiency is increased. If the angle is smaller than the above range,
The bag 78 is easily hooked and damaged by the moving claw 5, and the time required for breaking the bag becomes longer. That is, the processing capacity decreases.

At an angle larger than the angle in the above range, when a solid is caught between the dam plate 4 and the moving claw 5,
Even when the movable claw 5 is movable, it is difficult to smoothly release the solid matter, and as a result, dust 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. When 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 moving claw 5, and the time required for breaking the bag becomes longer. That is, the processing capacity decreases.

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 in the present embodiment, the blocking plate 4 is formed integrally and continuously with the plate 3 so that the tip of the plate 3 is gradually curved and located outside the tip orbit of the moving claw 5. What is formed is within the range of movement of the moving claw 5 (moving claw 5
(Between the tip track of the moving claw 5 and the blocking plate 4 or the plate 3) so that the angle between the imaginary line perpendicular to the track of the tip of the moving claw 5 and the tangent of the blocking plate 4 is always equal to or greater than zero degree (the blocking is performed). It is preferable that the dam plate 4 is gently curved so that the outer side of the plate with respect to the tangent line of the plate 4 is above a virtual line perpendicular to the trajectory of the tip of the movable claw 5). This allows the wire cord,
Even when foreign matter which is pushed by the moving claw 5 such as an electric wire cable, a hanger, and an umbrella and is deformed and easily clogs the slit 4A is caught, the blocking claw 4 is gently curved.
Even if it is pushed by, a foreign component force is generated against the foreign matter,
Removed automatically. This effect is achieved by moving the moving claw 5
It has an elastic member such as the torsion coil springs 20 and 22, and is capable of swinging or falling in the direction opposite to the moving direction in accordance with the resistance applied to the tip of the moving claw 5. Effectively demonstrated.

In the case where the partition between the dam plate 95 and the plate 94 is clear as shown in FIGS.
The angle φ between the dam plate 95 and the plate 94 (see FIG. 14) is preferably 60 to 120 degrees, more preferably 80 to 100 degrees.

Further, the relationship between the moving claw 5 and the dam plate 4 will be described. The effective claw length c, which is the vertical height of the claw above the plate 3 of the moving claw 5, is 100 mm to 200 mm.

The effective value c of the movable claw 5 differs depending on the size of the bag 78. If the size of the bag 78 to be processed has a width, it is also effective to combine the moving claws 5 of several lengths.

The slit width d of the blocking plate 4 is set so that only the movable claw 5 and the sack 78 that has been broken pass.
0 mm, preferably 20 mm to 35 mm. In addition, it is preferable that the gap between the moving claw 5 and the slit 4A of the dam plate 4 is 5 mm or more on both sides of the claw.

If the slit width d is narrow, 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 moving claw 5 will be described. The gap between the movable claw 5 and the slit 3A of the plate 3 is (thickness of the movable claw 5 + 0 mm to 30 mm), and preferably (thickness of the movable claw 5 + 10 mm to 20 mm). This gap is preferably as small as possible within a range where the moving 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 second 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 a range where the garbage can be discharged, the less the small bag containing the garbage is discharged without being caught by the moving claw 5.

When garbage is used for cans, bottles, and plastic bottles, the distance 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 the plurality of moving claws 5 are provided and the fixed blade 59 is provided in the plate 3 is shown, the invention is not limited to this, and instead of some of the plurality of moving claws 5, a blade capable of cutting a bag is provided. Of course, instead of some of the plurality of fixed blades 59, a nail having a strong action of hooking the bag may be provided.

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

Further, the waste discharging 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 discharging portion so that it can also be used as the waste discharging conveyor 74. May be.

As described above, according to the bag breaking apparatus according to any one of the first to eighth aspects of the present invention, for example, a bag filled with dust is hooked and moved by the moving claw, and the upper surface of the plate is moved. When passing through the positions of the plurality of fixed blades provided in the bag, since the bag is moved by the moving claw in a state where movement of the fixed blade is suppressed, the bag restrained by the fixed blade is moved with the movement of the moving claw. Due to the tearing action of tearing, continuous bag breaking operation is possible, and a plurality of fixed blades are provided on the upper surface of the plate, and the fixed blade extends from the bottom to the top like a moving claw Even if it is a small bag, even if it is a large bag, it can hit the fixed blade and reliably receive the tearing action by the moving claw and the fixed blade, and the transfer is not hindered by the fixed blade, Done smoothly, Because it does not cause clogging, it is easy to obtain a smooth transfer action and tear action for bags of various sizes, and it is easy to obtain packaging materials such as vinyl that packs the items to be packed. There is an advantage that the bag can be broken without being limited by the size of the bag to be formed, and the operability is excellent.

In particular, according to the bag breaking device of the second aspect of the present invention, since the upper portion of the fixed blade protrudes from the lower portion of the blade, the fixed blade hooks the bag and is moved by the movable claw. When tearing the bag, the bag is prevented from rising and the fixed blade can easily bite into the bag, and the bag can be broken more reliably.

According to the bag breaking device of the third aspect of the present invention, the claw has an elastic member, and can be swung or raised in the direction opposite to the moving direction in accordance with the resistance applied to the toe. Since the movable claw and the fixed blade are configured to be tiltable, an effect of removing a hard object caught between the moving claw and the fixed blade can be obtained, and the bag breaking process can be continuously performed without damaging the moving claw, the fixed blade and the like. .

According to the bag breaking device of the fourth aspect,
Since a plurality of fixed blades are provided at intervals along the slit direction, the bag caught on the moving claw can repeatedly receive the tearing action by the fixed blade and the moving claw,
The bag can be reliably broken.

According to the fifth aspect of the present invention, the movable claw has a slit which is formed close to, fixed to, or integral with the plate, and which is continuous with the slit of the plate, and through which the movable claw can pass. Since the blocking plate whose tip is located outside of the tip orbit of the claw is provided, it is possible to avoid as much as possible the situation in which the bag is discharged without being processed without being broken, and the bag is efficiently broken. An apparatus can be provided.

According to the sixth aspect of the present invention, the endless conveyor is provided such that the upper moving section is inclined so that the moving direction of the upper moving section is located at a higher position, and the plate is provided with: Since it is provided to be inclined above the endless conveyor along the inclination of the moving part on the upper side of the endless conveyor, the dust coming out of the bag is subjected to the tearing action of the bag by the fixed blade and the moving claw, and the dust coming out of the bag is placed on the lower side of the plate. The bag that has fallen in the direction of and was caught by the moving claw and broken by the moving claw is scraped up by the moving claw in the direction of the high side of the plate. In addition to being able to separate and collect, even if there is a bag that has come off from the moving claw without being broken, the bag can be caught by the moving claw again and subjected to the tearing action of the bag by the fixed blade and the moving claw, and stable. Continuous bag break Rotation is possible.

[0220] According to the invention according to claim 7, dust falling from the higher side of the plate collides with the inclined fixed blade provided on the plate, thereby reducing the falling speed. This has the effect of slowing down the shock at the time of collision between the bottles and preventing damage to the bottles and the like.

In the invention according to claim 8, the fixed blade is
Each side of the endless conveyor moving part (one side in the direction perpendicular to the moving direction) where the bag charging section is located is inclined high so that the other side of the endless conveyor moving part is low. Because it is provided along with the plate such as a bag that falls along the plate, it collides with the inclined fixed blade provided on the plate on the way, and most of it hits the other side of the endless conveyor moving part. As it falls, it moves to the other side of the endless conveyor moving part, does not stay in the bag charging part, and can be repeatedly subjected to the tearing action of the bag by the fixed blade and the moving claw. Repeated bag breaking action and transfer action can be obtained.
