DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foamed resin material crushing apparatus for crushing foamed resin materials such as styrofoam wastes discharged from supermarkets and factories.

[0002]

2. Description of the Related Art When various kinds of products are sold, a packaging material of a foamed resin material (including a protective material for packaging) is often used. Such a packaging material made of a foamed resin material becomes unnecessary after a consumer purchases a product, and there is a problem in its treatment. Also, a large amount of foamed resin material is discharged from a fish market, a factory, and the like, which is a problem as described above. For this reason, a treatment plant for chemically treating the foamed resin material is provided. For example, in a supermarket or the like, there is a case where a space for collecting the foamed resin material that is no longer needed after purchasing the product is provided, and the collected foamed resin material may be transported to the processing plant. They are also transported from fish markets and factories to treatment plants.

[0003]

However, since the foamed resin material has a small specific gravity and a large volume in proportion to the weight and is hard to deform, if a mere used foamed resin material is loaded on a truck, A large amount of useless space is generated between a large number of foamed resin materials, and the efficiency of transporting the foamed resin material is low. For this reason, it is necessary to crush finely before transportation.

Further, even when a used foamed resin material is simply carried into the above-mentioned processing plant, it is better to crush it finely before chemical treatment in order to increase the efficiency of the treatment. desirable.

Therefore, an object of the present invention is to provide an apparatus for efficiently crushing a foamed resin material.

[0006]

Means for Solving the Problems To solve this problem, the invention according to claim 1 comprises a housing, a fixed blade,
A foamed resin material crushing device having a rotary blade device, wherein the housing accommodates the foamed resin material,
The fixed blade is fixedly provided inside the housing, and a plurality of the fixed blades are provided in parallel with a gap therebetween, and the rotary blade device rotates around its own rotation axis inside the housing. A horizontal blade that is provided substantially parallel to the rotation axis and passes near the tip of the fixed blade with the rotation of the rotary blade device, and extends substantially radially from the rotation axis to rotate the rotary blade device. And a radiation blade passing through a gap between the plurality of fixed blades.

In the present invention, the rotating blade device rotates around its own rotation axis in a state where the foamed resin material is accommodated in the housing, so that the foamed resin is formed by the tip of the fixed blade and the horizontal blade of the rotating blade device. While the material is cut in the horizontal direction, the foamed resin material is cut in the vertical direction by the fixed blade and the radial blade of the rotary blade device, and is crushed. According to the present invention, since the cutting is performed in both the vertical and horizontal directions, the crushing is performed more finely than when the cutting is performed in only one direction. In addition, the above-described rotation of the rotary blade device guides the foamed resin material to the downstream side by both the rotating radial blade and the horizontal blade, so that the foamed resin material is more smoothly delivered than when only one of them is used. Further, since the cutting is performed by the fixed blade and the rotary blade device, the structure is simpler than when both are rotated, and the maintenance and the like are also easier.

According to a second aspect of the present invention, there is provided the foamed resin material crushing apparatus according to the first aspect of the present invention, wherein a plurality of radiation blade plates are provided along an axial direction of the rotary blade device, and the plurality of radiation blades are provided. The blade plate has a long radiation blade and a short radiation blade, and is a foamed resin material crushing device in which the phases of the plurality of radiation blade plates are different along the axial direction of the rotary blade device.

In the present invention, since the phases of the plurality of radiating blades are different along the axial direction of the rotary blade device, the long radiating blades of all the radiating blades simultaneously cut the foamed resin material. Is prevented and the load on the rotary blade device is reduced. Therefore, the life of the foamed resin material crushing apparatus can be extended. Note that "the phases of a plurality of radiation blades are different along the axial direction of the rotary blade device" does not require that all the radiation blades have completely different phases. The phases are not all the same. " Further, in the present invention, since the radiation blade plate has the long radiation blade and the short radiation blade, unlike the case where all the radiation blades have the same length, the same cutting action is performed on the same portion of the foamed resin material. That is alleviated. Therefore, useless cutting action is reduced, and the cutting action is made more efficient.

The invention according to claim 3 is a foamed resin material crushing device having a housing, a fixed blade, and a rotary blade device, wherein the housing accommodates the foamed resin material, and The blade is fixedly provided inside the housing, and a plurality of blades are provided in parallel with a gap therebetween, and the rotary blade device rotates around its own rotation axis inside the housing, and It has a radial blade extending substantially radially from the axis and passing through the gap between the plurality of fixed blades with the rotation of the rotary blade device,
Three or more radial blades are provided along the axial direction of the rotary blade device between adjacent fixed blades, and the phases of the radial blades at both ends thereof are substantially the same, and the phases of the radial blades between them are substantially the same. This is a foamed resin material crushing device having a phase different from that of the radiation blades on both ends.

According to the present invention, the foamed resin material is cut by the fixed blade and the radial blade of the rotary blade device by rotating the rotary blade device around its own rotation axis while the foamed resin material is housed in the housing. And crushed. Further, in this invention, the phases of the radiation blades at both ends of the three or more radiation blades provided along the axial direction of the rotary blade device between the adjacent fixed blades are substantially the same, and the radiation blades between the two fixed blades have the same phase. Because the phase is different from the phase of the radiation blades at both ends, after the foamed resin material is cut by the radiation blades and the fixed blades at the both ends, the radiation blades at the both ends of the foamed resin material are cut. Even if the portion in between stays in the cut place, it is cut or ejected by the radiating blade between the radiating blades on both ends. For this reason, the cut foamed resin material is prevented from staying at the cut position, and is smoothly discharged. Further, since three or more radiating blades are provided between adjacent fixed blades, compared with a case where one radiating blade is provided between each adjacent fixed blade, the distance between the adjacent fixed blades is reduced. The spacing (gap) increases (assuming the spacing between adjacent radiating blades is the same). For this reason, maintenance becomes easy.

According to a fourth aspect of the present invention, there is provided the foamed resin material crushing apparatus according to the first or second aspect of the present invention, wherein the upstream side of the foamed resin material crushing apparatus is a coarse crushing apparatus. It is a foamed resin material crushing device provided with the device.

As shown in FIG. 2, the fixed blade 30 has a vertical plate shape, and the tip thereof is inclined from the upper side to the lower side toward the right side in the drawing. A cover 34 is provided above the fixed blade 30.

The rotary blade device 50 (FIG. 1) includes a housing 2
0, it is provided rotatable about its own rotation axis (center axis) as follows. As shown in FIGS. 2 and 3, the rotary blade device 50 has a rotary shaft 52, a pair of support plates 56, a large number of radial blade plates 60, and horizontal blades 70.

The housing 20 (FIG. 1) has a pair of supporting side walls 26 (FIG. 2). The rotation axis 52 is
It is provided over both supporting side walls 26. Rotary axis 5
2 is provided rotatably with respect to each supporting side wall 26 via a bearing 54.

Each support plate 56 is fixed to the rotation shaft 52 near the inside of each support side wall 26. A large number of radiation blade plates 60 are fixed to the rotation shaft 52 between the two support plates 56. Spacers 58 are interposed between the plurality of radiation blade plates 60. The rotating shaft 52 has a non-circular cross section between the two supporting side walls 26, and the supporting plate 56, the spacer 5
8. Each through hole 57, 59, 6 formed in the radiation blade plate 60
1 is also non-circular. The rotation shaft 52 passes through the through holes 57, 59, 61, thereby preventing the support plate 56, the spacer 58, and the radiation blade plate 60 from rotating.

Each radiating blade plate 60 is provided corresponding to a gap between the fixed blades 30. That is, the adjacent fixed blade 30
The radiation blade plates 60 are provided so as to be positioned one by one corresponding to each gap between them. The radiation blade plate 60 is formed with six radiation blades 62 (62a, 62b). Each radial blade 62 extends substantially radially at equal angular intervals (60 degrees apart). As the radiation blade 62, a long radiation blade 62
a and three short radial blades 62b, which are alternately formed. Any of the radiation blades 62 (62a, 62)
b) also passes through the gap between the adjacent fixed blades 30 as the rotary blade device 50 rotates.
The radiation blade plates 60 are grouped in groups of four along the axial direction of the rotating shaft 52, and the same group has the same phase, and the different groups have different phases. That is, in the same set, the radiation directions of the long radiation blade 62a and the short radiation blade 62b are the same, and the phases are shifted by 60 degrees between adjacent pairs.

The six horizontal blades 70 are provided in parallel with the rotating shaft 52 over both support plates 56. Both support plates 56 have a substantially star shape, and each horizontal blade 70 is fixed to a surface directed substantially in the radial direction. For this reason, the width direction of each horizontal blade 70 is substantially the same as the radial direction of the support plate 56. Each horizontal blade 70 penetrates each radiation blade plate 60. Each of the horizontal blades 70 passes near the distal end of each of the fixed blades 30 as the rotary blade device 50 rotates. The horizontal blade 70 is provided at such a position.

Returning to FIG. 1, the rotary blade device 50 includes a motor 8
0 is accompanied. A sprocket 55 is provided at one end of the rotary shaft of the rotary blade device 50 (outside the support side wall 26), and a chain 84 is provided between the sprocket 82 provided on the rotary shaft of the motor 80 and the sprocket 55.
Has been passed over. Therefore, the rotating blade device 50 (the rotating shaft 52) rotates with the rotation of the motor 80 (the rotating shaft).

Next, the operation and effect of the foamed resin material crushing apparatus 10 will be described. The foamed resin material is charged into the foamed resin material charging section 22 (FIG. 1). When the rotary blade device 50 rotates, the foamed resin material is transferred to the horizontal blade 70 and each fixed blade 3.
0 (its tip) is cut in the horizontal direction.
At the same time, the foam resin material is applied to each of the radiation blades 62 (62a,
62b) and each fixed blade 30 cuts at a number of locations in the vertical direction. Thus, the foamed resin material is crushed and sent out from the treated foamed resin material sending section 24.

As described above, the foamed resin material crushing apparatus 10
In this case, since it is cut in both the horizontal and vertical directions (at many points in the vertical direction) at the same time, it is crushed more finely than when it is cut in only one direction.

Further, since a large number of radiation blade plates 60 are grouped in groups of four, and the phases are shifted by 60 degrees for each group, the blades are crushed more smoothly than when all the phases are the same. That is, when the phases are all the same, all the radiation blade plates 60
There is a timing at which the long radial blade 62a simultaneously cuts the foamed resin material, in which case a large load is applied to the rotary blade device 50. However, in this foamed resin material crushing apparatus 10, since the phases of the radiation blades 60 are shifted for each set, even when the maximum load is applied, half of the radiation blades 60 of the entire radiation blades 60 have long radiation blades. 62a;
Since the other half of the radiation blades 60 and the short radiation blades 62b of the radiation blade plate 60 simultaneously perform the cutting action, the load can be reduced and the crushing can be performed smoothly.

In the foamed resin material crushing apparatus 10,
Because it is crushed by the fixed blade 30 and the rotary blade device 50,
Maintenance is easier than in the case where there are a plurality of rotating objects.

[Embodiment 2] Next, Embodiment 2 of the present invention
5 through FIG. 7 focusing on differences from the first embodiment.
It will be described based on. This foamed resin material crusher 100
Is provided on the upstream side of the fine crusher 11
Is provided. The fine crusher 11 is almost the same as the foamed resin material crusher 10 of the first embodiment. Corresponding members have the same reference characters allotted, and description thereof will not be repeated.

The coarse crushing apparatus 110 includes a housing (coarse crushing housing) 120 and a fixed blade (coarse crushing fixed blade).
130, a rotary blade device (rotary blade device for coarse crushing) 150, and has a structure similar to that of the foamed resin material crushing device 10 of the first embodiment.

An upper part of the housing 120 is an opening 122, and a lower part thereof communicates with the housing 20 of the crusher 11. On one side of the housing 120,
An inclined wall portion 123 is formed.

The fixed blade 130 is fixed to the inclined wall 123. In this case, five are provided. Each fixed blade 130
Is wider than in the case of the foamed resin material crushing apparatus 10 of the first embodiment. The fixed blades 130 are alternately provided at positions slightly shifted in the inclination direction of the inclined wall portion 123.

The rotary blade device 150 is provided as follows. The rotating shaft 152 is rotatably provided with respect to the supporting side wall 126 of the housing 120.
A large number of radiation blade plates 160 are fixed to 2. Three radiation blade plates 160 are provided corresponding to each gap between the adjacent fixed blades 130. The radiation blade plate 160 has two radiation blades 162 which are in a straight line as a whole and are directed in opposite directions. The adjacent radiation blade plates 160 are alternately shifted in phase by 90 degrees. A sprocket 155 is provided at one end of the rotating shaft 152, and the motor 1
A chain (not shown) is hung between a sprocket (not shown) provided on the rotating shaft of 80 (FIG. 5), and the rotary blade device 150 is rotated by the rotation of the motor 180.

Next, the operation and effect of the foamed resin material crushing apparatus 100 will be described. The foamed resin material is put into the housing 120 through the opening 122 of the coarse crushing device 110. The foamed resin material descends along the slope of the inclined wall portion 123. And
As the rotary blade device 150 rotates, the foamed resin material is roughly cut by the radial blade 162 and the fixed blade 130. In this way, the roughly crushed foamed resin material flows into the fine crushing device 11 and is finely crushed as described in the first embodiment. For this reason, crushing in the fine crushing device 11 becomes smoother.

In the above-mentioned coarse crushing, since the phases of the adjacent radiation blades 160 are alternately shifted by 90 degrees,
Fragmentation is smoother than when all phases are the same. That is, even when the maximum load is applied, half of the radiation blades 162 out of the number of the radiation blades 160 simultaneously perform the cutting action, and the radiation blades 162 of all the radiation blades 160 simultaneously perform the cutting action. Therefore, an excessive load is not applied to the rotary blade device 150. Further, when the two rotary blades are located in the gap between the adjacent fixed blades 130, the foam resin material is cut (coarsely crushed) by the two radial blades 162, and between the two radial blades 162 of the foam resin material. If the portion remains in that position, it will be cut or eliminated by the next (ie, after rotating blade device 150 has been rotated 90 degrees) one radiating blade 162.
Thus, the foamed resin material is roughly crushed and discharged smoothly.
