A specific example will be described below with reference to the attached figure.

[First Embodiment]
The shatterproof member and the hopper member are installed in, for example, the following crusher.

[Example of crusher]
FIG. 1 is a diagram showing an example of a crusher 100. Hereinafter, the direction of gravity will be referred to as the "Z-axis direction". Further, the direction of the width of the crusher 100 is defined as the "X-axis direction". Further, the direction of the depth of the crusher 100 is defined as the "Y-axis direction".

For example, the crusher 100 has a hardware configuration including a hopper member 101, a crushing chamber 102, a motor 103, and the like.

The crusher 100 may further include a tank 104, a housing, and the like. As described above, the crusher 100 may have peripheral devices such as a tank 104. Further, as shown in the figure, there may be a pedestal portion or the like that supports these components and peripheral devices.

The tank 104 is, for example, an S tank or a T tank.

[About input materials]
Hereinafter, the object to be crushed by the crusher 100 is referred to as an "input material". The input material is, for example, resin or the like. The input material may include a material other than resin or the like as long as it is a material that can be crushed by the crusher 100. For example, the input material may include wood, metal, ceramic and the like.

For example, the input material is manufactured by injection molding as follows.

FIG. 2 is a diagram showing a manufacturing example of the input material. For example, the input material is a molded product 10 or the like manufactured by the following injection molding.

As shown in the figure, the molded product 10 is manufactured by injecting resin from the injection forming machine 12 into the mold 11. Hereinafter, a cross-sectional view of the mold 11 will be described.

For example, even when the main body portion 13 is manufactured, the molded product 10 is manufactured so as to have a runner 14, a sprue 15, a gate 16, and the like.

The sprue 15 is a portion formed according to a path for resin to flow from the nozzle of the injection forming machine 12 to the central portion of the mold 11.

The runner 14 is a portion formed according to the path through which the resin flows from the sprue 15 portion to the gate 16.

The gate 16 is a portion formed according to a path for the resin to flow from the runner 14 to the portion forming the main body portion 13.

When the main body portion 13 is manufactured by injection molding, the runner 14, the sprue 15, the gate 16, and the like are also manufactured. Therefore, the volume of the molded product 10 is increased by the runner 14, the sprue 15, the gate 16, and the like.

For example, the molded product 10 is used as an input material when the molded product 10 is discarded. As described above, since the molded product 10 has a large volume, when it is crushed by the crusher 100, the runner 14, the sprue 15, the gate 16, and the like become granular, so that the waste volume can be reduced.

Further, when the molded product 10 is reused as a material used for injection molding, the molded product 10 is often made into granules. Therefore, the molded product 10 is crushed by the crusher 100 to granulate the material used for injection molding.

For example, as described above, the input material is to be crushed by the crusher 100 for granulation, disposal, or the like.

[Example of hopper member]
For example, the shatterproof member is installed inside the hopper member 101 as shown below.

FIG. 3 is a diagram showing an example of the hopper member 101. Hereinafter, the description will be given in the “XY” plane.

The hopper member 101 has at least openings such as an inlet 201 and an outlet 202.

The charging port 201 is an opening into which the input material is charged. Therefore, when the material is charged into the charging port 201, the input material is inserted into the hopper member 101.

The outlet 202 is an outlet of the hopper member 101, and is an opening that serves as an entrance to the crushing chamber 102 when the hopper member 101 is connected to the crushing chamber 102.

For example, the input port 201 is installed at the upper part of the hopper member 101. On the other hand, the outlet 202 is installed below the hopper member 101. In such a relationship, the input material falls due to gravity when it is charged into the input port 201. After that, the input material moves to the outlet 202, that is, the crushing chamber 102 through the hopper member 101. In this way, the input material charged into the hopper member 101 is crushed.

[Example of crushing room]
The crushing chamber 102 is a mechanism having, for example, a cutter or the like. Then, the cutter is rotated by being driven by an actuator such as a motor 103, and the input material is finely crushed.

The crushing chamber 102 may have a mechanism capable of crushing the input material input from the inlet. For example, the motor 103 may be integrated with the crushing chamber 102.

[Example of shatterproof member]
The shatterproof member is installed on the inner wall of the hopper member 101, for example. Specifically, for example, the shatterproof member is installed at the following positions.

FIG. 4 is a diagram showing an example of a position where the shatterproof member is installed. The figure is an oblique projection view showing the hopper member 101 shown in FIG. 3 from a viewpoint where the inner wall can be seen.

For example, the shatterproof member is installed at an installation location (hereinafter referred to as "installation location 203") in the figure. In this example, the installation location 203 is an inclined surface of the hopper member 101.

The installation location 203 may be between the inlet 201 and the outlet 202 (that is, the entrance of the crushing chamber 102). For example, when the shatterproof member is installed at the installation location 203, the result is as follows.

FIG. 5 is a diagram showing an installation example of the shatterproof member. For example, the shatterproof member is a seesaw component 20 composed of a plate 21 which is an example of a plate material, a shaft member 22 which is an example of a support material, and the like.

When the configuration of the same seesaw component 20 is shown in the XY plane, that is, the side view, it can be shown as follows.

FIG. 6 is a diagram showing a configuration example and an installation example of the shatterproof member. As shown in the figure, the seesaw component 20 is a mechanism in which the plate 21 rotates around the shaft member 22 as the center of rotation. Specifically, the plate 21 is a rotation about the Y-axis with the shaft member 22 as the center of rotation (in the figure, it is the rotation indicated by the arrow of the pitch rotation PT).

In this example, the first end PS1 is the end of the plate 21 that is closest to the outlet 202 (the leftmost position in the figure). On the other hand, in this example, the second end portion PS2 is the end portion of the plate 21 that is closest to the insertion port 201 (the position on the rightmost side in the figure).

Further, the plate 21 has a shape, an angle, and a position such that the first end PS1 is inclined to be lower than the second end PS2 in the initial state and in the state where there is no input material 105. It is desirable to be installed. With such an inclination, when the input material 105 is charged, it slides down the inclination due to its weight and moves toward the first end portion PS1. As described above, when the input material 105 is charged onto the plate 21, it is desirable that the plate material is installed so as to have an inclination that easily slides down from the plate 21 to the outlet 202.

Further, the plate 21 and the shaft member 22 are installed so that most of the plate 21 is located between the inlet and the inlet 201 of the crusher. The plate 21 has a size that closes the opening to the outside such as the input port 201 in the initial state and the like, and is installed at an angle and a position that closes the opening to the outside in the initial state and the like. ..

When the input material is charged, the seesaw component 20 rotates so that the first end portion PS1 falls in the direction of gravity (moves downward in the figure). That is, the seesaw component 20 is a mechanism that performs pitch rotation PT in which the plate 21 rotates counterclockwise in the figure when the input material is charged. In this case, the second end PS2 rotates so as to be lifted (moved upward in the figure). Specifically, the seesaw component 20 rotates as follows when the input material is charged.

FIG. 7 is a diagram showing an example when the input material 105 is charged. For example, when the input material 105 is charged, the seesaw component 20 receives the input material 105 on the plate 21. Even when the input material 105 is received at a position close to the second end portion PS2, the plate 21 is inclined, so that the input material 105 has the first end portion due to the relationship between gravity and the moment of force. Move to the PS1 side. Therefore, as shown in the figure, the plate 21 receives the input material 105 at a position close to the first end portion PS1.

In this way, when the plate 21 receives the input material 105, the first end portion PS1 falls in the direction of gravity due to the weight of the input material 105. On the other hand, the second end PS2 is lifted.

Therefore, as compared with FIG. 6, in FIG. 7, the first end PS1 is located lower in the Z axis than in FIG. On the other hand, as compared with FIG. 6, in FIG. 7, the second end PS2 is located above the Z axis from FIG. When rotated in this way, the input material 105 can fall and reach the outlet 202 because the passage to the outlet 202 is secured.

On the other hand, when the input material 105 passes through, that is, when the input material reaches the outlet 202 and disappears from the seesaw component 20, the seesaw component 20 becomes as follows.

FIG. 8 is a diagram showing an example when the input material 105 has passed. As shown in the figure, when the input material 105 passes, the plate 21 rotates so as to return to the original state due to a restoring force or the like. The restoring force may be generated by a mechanism such as a spring. In this example, the plate 21 performs pitch rotation PT that rotates clockwise around the shaft member 22 from the state shown in FIG. 7.

In this way, when the input material 105 passes through the seesaw component 20, the first end portion PS1 is lifted and the second end portion PS2 is rotated so as to fall in the direction of gravity. By performing such rotation, it is possible to prevent the fragments from scattering while the input material 105 is being crushed.

Specifically, as shown in FIG. 8, when the first end portion PS1 is in a high position (upward in the figure) while the input material 105 is being crushed, the opening 106 can be narrowed.

Even if the debris is scattered by the crushing of the input material 105, if the debris is scattered below the first end portion PS1 (hereinafter, simply referred to as "lower part 107"), the debris is scattered from the input port 201 to the outside by the plate 21. You can prevent it from happening. Therefore, if the first end PS1 is lifted and the first end PS1 is set to a high position, the lower 107, that is, the range in which scattering can be prevented can be widened.

As described above, while the input material 105 is being crushed, the narrower the opening 106 is, the smaller the probability that debris is scattered from the input port 201 to the outside can be reduced. In this example, the higher the first end PS1 is, the narrower the opening 106 is. Therefore, as shown in FIG. 8, it is desirable that the first end portion PS1 is lifted as much as possible when the input material 105 passes through.

On the other hand, when the input material 105 is charged, it is desirable that the opening 106 is wide so that the input material 105 can pass through even if the volume is large. Therefore, when the input material 105 is charged, it is desirable that the first end portion PS1 falls in the direction of gravity due to the weight of the input material 105, as shown in FIG. As described above, if the opening 106 is widened by the weight of the input material 105, a mechanical component such as an actuator for widening the opening 106 is not required, and a simple structure can be obtained. Further, if the configuration has a small number of mechanical parts, the cost can be reduced.

When the input material 105 is crushed and debris or the like is scattered, the debris adheres to the mold placed outside and causes a defect or the like. Further, when the input material 105 is crushed and debris or the like is scattered, the debris is mixed with the material for another process or the like outside, which causes foreign matter to be mixed. In this way, scattering of debris and the like causes various defects.

If the mechanism is rotatable as shown in FIGS. 6 to 8, the seesaw component 20 can prevent the scattering of debris and the like. Therefore, it is possible to prevent defects or foreign matter from being mixed in due to scattering of debris and the like.

Further, the type of the plate material (mainly the weight, the length, etc.) and the position of the support material are adjusted according to the type of the input material 105, the area of the outlet 202, and the like. desirable.

That is, when the weight of the input material 105 is large, when the input material 105 is received, a large force is applied to the first end portion PS1 due to the weight of the input material 105. Therefore, even when the moment of force of the plate 21 is large, the seesaw component 20 can rotate so that the first end portion PS1 falls in the direction of gravity, as shown in FIG. 7.

On the other hand, when the weight of the input material 105 is small and the moment of force of the plate 21 is large, the seesaw component 20 rotates so that the first end portion PS1 sufficiently drops in the direction of gravity as shown in FIG. difficult. In such a case, adjust the length of the first end PS1 and the shaft member 22, the ratio of the length of the second end PS2 and the shaft member 22, the type of the plate 21, etc., and make a small force. However, it is desirable that the plate 21 be adjusted to rotate. In addition, there may be a mechanism or the like that can adjust the ease of rotation by adding a weight such as a weight to the first end PS1 side or the second end PS2 side.

Therefore, it is desirable that the seesaw component 20 is a mechanism by which the plate 21 can be replaced or the position of the shaft member 22 can be changed. With such a mechanism, it is possible to deal with various types of input materials 105.

As described above, it is desirable that the plate material has a weight and a length (mainly the dimensions in the X-axis direction in the figure) that rotate with respect to the charging and passing of the input material 105. On the other hand, it is desirable that the plate material has a width that almost closes the input port 201 (in the figure, it is a dimension in the Y-axis direction). Further, the plate material is not limited to the flat plate, and may have other shapes.

The support material has a shape such as a cylinder, such as a shaft member 22 or the like. The support material may have any shape as long as it can support the plate material and is fixed to the inner wall of the hopper member 101 by a mechanism for rotating the plate material. As shown in the figure, for example, the support material supports the plate material at a point between the first end portion PS1 and the second end portion PS2.

[First modification]
The plate material preferably has the following structure.

FIG. 9 is a diagram showing a first modification. Hereinafter, as shown in the figure, an example of the first surface as the first surface PA1 and an example of the second surface as the second surface PA2 will be described. Further, a predetermined angle formed by the second surface PA2 with respect to the plane formed by the first surface PA1 is defined as an “angle θ”. The angle θ is an angle around the Y-axis, a so-called pitch angle.

The plate 21 has a shape including, for example, a second surface PA2 having an angle θ in the direction of gravity with respect to the first surface PA1 including the second end portion PS2. The second surface PA2 has a shorter dimension in the X-axis direction than the first surface PA1. Specifically, the plate 21 is the following plate material.

FIG. 10 is a diagram showing an example of a plate material in the first modification.

The first surface PA1 is the surface that becomes the majority of the plate 21. The first surface PA1 may have an area sufficient to receive the input material 105.

The angle θ is preferably 5 ° or more and less than 90 °.

With the second surface PA2, the plate 21 has a portion whose angle is steeper in the direction of gravity than the first surface PA1. If there is a portion having such an angle θ, the input material 105 tends to fall to the outlet 202.

That is, if the second surface PA2 is provided, it is possible to easily prevent the input material 105 from being caught in the middle and being clogged.

Further, as shown in the figure, the second surface PA2 is not limited to a configuration in which a part of the plate 21 is manufactured by bending or the like. For example, the second surface PA2 may be formed by adding parts to the tip of the first end portion PS1 shown in FIG. 6 (on the left side in the figure). Therefore, the first surface PA1 and the second surface PA2 may be integrated or may be configured by combining different parts.

The length and ratio of the second surface PA2 (that is, the ratio of the first surface PA1 and the second surface PA2 on the plate 21) are not limited to the configurations shown. That is, the length, ratio, etc. of the second surface PA2 may differ from the illustrated example depending on the weight of the input material 105, etc.

[Second modification]
The plate material may have the following lengths.

FIG. 11 is a diagram showing an example of a plate material in the second modification. For example, the plate material may be an extension plate 210 or the like shown.

The extension plate 210 has a length on the PS1 side of the first end portion of the shaft member 22 in the X-axis direction as compared with the plate 21 and the like in the first modification (in the figure, it corresponds to the length on the left side of the shaft member 22. The length indicated by "long side portion 211") is long.

It is desirable that the plate material has a long side portion 211 like the extension plate 210 and closes the opening range of the outlet 202 (in the figure, it is the “opening range 212”).

It is desirable that the long side portion 211 has a length that closes the opening range 212 by half or more in the X-axis direction. More preferably, the long side portion 211 has a length that closes the opening range 212 by 70% or more. As described above, if the plate material has a length that can widely block the opening range 212, the probability that the fragments are scattered to the outside can be reduced.

The extension plate 210 changes the curvature of the plate material in the middle so that the first end portion PS1 does not reach the outlet 202 (in the figure, the position in the Y-axis direction reaches the position of the outlet 202). It may be processed or the like.

[Third variant]
It is desirable that the shatterproof member further includes a heavy part as follows.

FIG. 12 is a diagram showing a third modification. For example, the weight portion is realized by a mechanism in which a weight 301, which is an example of a weight, and a support rod 302 that supports the weight 301 are attached to a shaft member 22 that is an axis of the center of rotation.

The weight 301 is, for example, a weight or the like. The weight 301 may be a weight, and the material, shape, and quantity are not limited. Further, the weight 301 may be detachable and may be changed to a weight having a different weight or the like.

The support rod 302 is, for example, a rod-shaped member installed so as to be orthogonal to the shaft member 22. The support rod 302 may have any length, material, shape, and quantity as long as the weight 301 can be fixed to the shaft member 22.

The weight portion is configured to be movable so as to change the distance to the shaft. Specifically, the weight 301 has a configuration in which the distance to the shaft member 22 can be changed by moving along the support rod 302. That is, the weight portion has a configuration in which the distance of the weight 301 with respect to the shaft member 22 can be changed by, for example, a so-called slider mechanism or the like. In the figure, the movable range of the weight 301 is indicated by an arrow.

In this way, if the distance can be changed by moving the weight closer to or further from the support material, the initial angle of the plate material or the like can be adjusted.

For example, when the input material 105 is light, the distance is changed so that the weight 301 is closer to the shaft member 22. As described above, when the weight 301 is close to the shaft member 22, the plate member is likely to rotate. That is, even a light input material 105 can be rotated by the weight of the input material 105 so that the input material 105 can easily pass through.

When the distance of the weight to the axis of rotation is changed, the moment of force due to the weight changes even if the mass of the weight is constant. Therefore, by adjusting the moment according to the distance, the ease of rotation can be adjusted. As described above, the weight portion may have a structure capable of adjusting the moment of force. For example, the weight of the weight may be changed.

As described above, when the shatterproof member is configured to include a heavy part, the reaction of rotation can be adjusted according to the types of various input materials 105.

[Second Embodiment]
The hopper member 101 may be configured to include both a shatterproof mechanism and a shatterproof member as described below.

FIG. 13 is a diagram showing an example of the second embodiment. For example, it is desirable that the shatterproof mechanism and the shatterproof member are used in combination as follows.

The shatterproof mechanism is, for example, a curtain 30. Hereinafter, an example in which the shatterproof mechanism is the curtain 30 will be described. The shatterproof mechanism is not limited to the curtain 30, and may be, for example, a metal plate or the like. However, it is desirable that the shatterproof mechanism is a material that is flexible enough to move when pushed by the weight of the input material 105, such as the curtain 30, or a mechanism that moves.

Further, the curtain 30 may have a cut (such as inserting a slid in the Z-axis direction in the figure). Such a cut can reduce the possibility of preventing the input material 105 from passing through.

For example, as shown in the figure, the curtain 30 is installed on the back side (on the left side in the figure) of the input port 201 from the seesaw component 20. The position where the curtain 30 is installed may be any position as long as it is between the inlet 201 and the outlet 202. For example, the curtain 30 may be installed at a position overlapping the seesaw component 20 in the X-axis direction.

It is desirable that the position where the curtain 30 is installed and the area of the curtain 30 are a combination that blocks the route to the outlet 202 together with the plate material.

It is desirable that the curtain 30 is mainly installed in an area and a position that closes the opening 106 above the first end PS1.

On the other hand, the seesaw component 20 closes the lower portion 107.

With such a combination, the appearance is as follows.

FIG. 14 is a diagram showing a combination example of the curtain 30 and the seesaw component 20. As shown in the figure, the hopper member 101 can hardly see the outlet 202 from the viewpoint of the input port 201 due to the curtain 30 and the seesaw component 20 while the input material 105 is crushed in the crushing chamber.

As described above, if the curtain 30 closes the opening 106 and the seesaw component 20 closes the lower portion 107 while the input material 105 is crushed in the crushing chamber, there is no gap for the fragments to scatter to the outside. .. Therefore, when the combination of the curtain 30 and the seesaw component 20 is provided, the hopper member 101 can reduce the probability that the debris is scattered to the outside.

[Other Embodiments]
The shatterproof member is not limited to being installed at the position illustrated above, that is, on the inner wall of the hopper member 101. For example, the crusher 100 may be provided with an additional hopper member 110 or the like as follows.

FIG. 15 is a diagram showing an example in which the additional hopper member 110 is installed. As described above, options such as the additional hopper member 110 may be added to the crusher 100. In such a case, the shatterproof member may be installed on the additional hopper member 110. As described above, the shatterproof member may be installed at any position as long as it is in the stage before the crushing chamber.

It is desirable that the plate material and the support material are manufactured of, for example, a practical metal such as stainless steel, aluminum, iron, titanium, or magnesium.

The structure, shape, and the like of the hopper member 101 are not limited to the above examples as long as they are members that receive the input material to be charged into the crusher.

Similarly, the crusher is not limited to the above example as long as it is a device for crushing the input material. Further, the crusher may be called a flour mill or the like.

The present invention is not limited to the above-exemplified embodiments, and various modifications can be made without departing from the technical gist thereof, and the present invention is included in the technical idea described in the claims. All of the above technical matters are the subject of the present invention. Although the above embodiment shows a suitable example, those skilled in the art can realize various modified examples from the disclosed contents.
