Description

  The present invention relates to a volume reduction machine, and more particularly, to a volume reduction machine that improves the transfer efficiency such as using a truck by reducing the volume of a material to be reduced, which is a resin molded body such as a collected bumper for a vehicle.

  When the recovered resin molded body is reused as a resource, for example, the crusher disclosed in Patent Document 1 is used, and the resin molded body is crushed into a reusable state. In order to ensure the quality of the resin moldings that can be reused, different materials are not mixed and processing with only the same material is required. It is important to

  For example, a bumper for a vehicle, which is a resin molded body that is removed from a vehicle and collected, is formed of a different material depending on the so-called vehicle manufacturer and its manufacturing time, so that the crushing operation is practiced by separating the material. Is vital.

Japanese Patent Laid-Open No. 2003-135989 (see paragraphs 0001, 0016, 0017, FIGS. 1 and 2 in the specification)

  However, in the proposal disclosed in Patent Document 1 described above, there is basically no problem in that it is possible to practice the crushing of the bumper which is a resin molded body, but there are minor problems when considering the actual use. Invite.

  In other words, when the crushing operation using the crusher described above is performed at a specialized factory, for example, a crusher for each different material is prepared at the specialized factory, but the bumper that is removed from the vehicle and collected. It is indispensable to transport to the specialized factory.

  At this time, the bumper that is removed from the vehicle and collected in many cases has the same shape, that is, a complicated three-dimensional shape. The transfer efficiency becomes worse.

  Therefore, in order to improve the transfer efficiency of the recovered bumper, it is desirable to reduce the volume of the bumper, that is, to reduce the volume of the material to be reduced, which is a resin molded product. In fact, there is no suggestion of a volume reduction machine suitable for processing.

  By the way, in order to avoid volume reduction processing for the volume-reduced material, the proposal to crush the volume-reduced material for each material at the collection site of the volume-reduced material is based on multiple crushers at the volume-recovered material collection site. Therefore, it can be said that it is not feasible.

  The present invention was devised in view of the current situation, and the object of the present invention is to reduce the volume of the material to be reduced, which is a resin molded body, to improve the transfer efficiency by a truck, etc. It is to provide a volume reduction machine that is optimal for expecting an improvement in production.

In order to achieve the above-described object, the problem-solving means of the present invention is a volume reducing machine for reducing a volume-reduced material having a bent portion, and an upper rotating body that rotates about a first rotating shaft; A lower rotating body that is provided below the upper rotating body and that forms a gap with the upper rotating body and rotates about the second rotation axis. Rolling means for forming a volume reduction body by rolling the material to be reduced by passing the volume material, and conveying means for conveying the volume reduction body formed by the rolling means in a predetermined conveyance direction, the rolling means in a state but which is tilted to the opposite side with respect to the conveying direction, the first rotary shaft is provided on the upstream side with respect to the conveying direction, the second rotation shaft provided on the downstream side with respect to the transport direction It is characterized by being able to.

  More specifically, for example, it is assumed that the upper rotating body and the lower rotating body are rotated in opposite directions while keeping the gap between 0 mm and 3 mm. It is assumed that one of the lower rotating bodies has a mold blade on the outer periphery while the other has no mold blade on the outer periphery.

  Therefore, in the present invention, the material to be reduced, which is a resin molded product, is rolled by a rolling means to form a volume reducing material. Therefore, even if the material to be reduced has a complicated three-dimensional shape, it is almost rolled. Since the volume reduction processing is performed in a plate shape and the volume reduction body is transported by the transport means, the volume reduction bodies can be accumulated in a stacked state outside the transport means as the transport destination.

  At this time, the material to be reduced, which is a resin molded body, has its material indication, but since the material is simply rolled and volume-reduced in a plate shape, the material indication is not lost in the volume reduction body, Does not interfere with sorting for each material crushing operation.

  Then, the rolling means is tilted to the front side of the rolling means, and the gap between the upper rotating body and the lower rotating body that receives the material to be reduced in the rolling means is made to face diagonally downward on the front side of the rolling means. Therefore, compared with the case where this gap is directly opposite to the rolling means, the supply work to the rolling means by the operator of the volume-reduced material having a complicated three-dimensional shape before rolling is facilitated. To do.

  Further, in the present invention, for example, when the upper rotating body and the lower rotating body are rotated in opposite directions while keeping the gap between 0 mm and 3 mm, it is effective without causing the material to be reduced to be crushed. Rolling can be performed, and the volume-reducing body can be discharged to the conveying means side while avoiding the loss of the material display described above.

  When one of the upper rotator and the lower rotator has a die blade on the outer periphery, the sliding resistance of the rotator having the die blade against the volume-reduced material to be rolled increases, Can be discharged.

  On the other hand, a bumper made of a resin molded body, which is a material to be reduced, has many so-called protrusions such as reinforcing ribs and connecting parts on the inner side that are not exposed to the outside when mounted on the vehicle, but these protrusions are effective with a mold blade. The material to be reduced is rolled under the state and subjected to volume reduction treatment, thereby obtaining a preferable substantially plate-like volume reduction body.

It is a schematic elevation view which shows the volume reduction machine by this invention. It is a schematic perspective view which shows the upper rotary body and lower rotary body in a rolling means. It is a diagram which shows the type | mold blade formed in the outer periphery of an upper rotary body It is a figure which shows the type | mold blade of other embodiment similarly to FIG. It is a diagram which shows the cross section of a mold blade.

  Hereinafter, the present invention will be described based on the illustrated embodiment. The volume reducing machine according to the present invention basically includes rolling means 1 and conveying means 2 as shown in FIG. Thus, the illustrated embodiment further includes stocker means 3.

  And this volume reduction machine rolls the to-be-reduced material W which is the resin molding body supplied manually by an operator, ie, the bumper removed from the vehicle in the figure by the rolling means 1 in a substantially plate shape. Thus, the volume reduction body W1 is formed, and the volume reduction body W1 is transported by the transport means 2 and discharged to a predetermined location outside the transport means 2.

  At this time, when the stocker means 3 is adjacent to the outside of the conveying means 2, a large number of the volume reduction bodies W <b> 1 are collected in a stacked state by the stocker means 3.

  The volume reduction machine according to the present invention may be provided indoors or outdoors in a specialized factory, but as described above, when the material to be reduced W, which is a bumper removed from the vehicle, is transferred to the specialized factory. In addition, it is so-called bulky that it deteriorates the transfer efficiency.

  In view of this, the volume reduction machine is loaded on a loading platform in a vehicle having a driving structure such as a truck, or is loaded on a loading platform in a towing structure vehicle such as a trailer and can be moved. It would be preferable to set it so that it can be dispatched to a so-called field where the bumper removed from the car is accumulated.

  When this volume reduction machine is loaded on a loading platform such as a truck, the stocker means 3 may be loaded together on the loading platform, or may be loaded on the loading platform of another vehicle.

More specifically, first, the rolling means 1 has an upper rotating body 11 and a lower rotating body 12 that rotate about the first rotating shaft 11a and the second rotating shaft 12a, respectively, to form a roll structure. The volume-reducing material W, which is a bumper made of a resin molded body, is rolled by passing through a gap appearing between the upper rotating zone 1 and the lower rotating body 12 to obtain a volume-reducing body W1 having a substantially plate shape.

Therefore, in this rolling means 1, basically, the rotating shafts 11 a and 12 a of the upper rotating body 11 and the lower rotating body 12 extend in the horizontal direction that is the same direction (see FIG. 2). Specifically, the rotating shafts 11a and 12a in the upper rotating body 11 and the lower rotating body 12 extend in a horizontal direction crossing an axial direction which is a transport direction in the transport means 2 described later.
And the rolling means 1 is inclined to the opposite side with respect to the conveying direction, the first rotating shaft 11a is provided on the upstream side with respect to the conveying direction, and the second rotating shaft 12a is provided on the downstream side with respect to the conveying direction. ing.

  As a result, when the volume reduction body W1 that is a rolled material to be reduced discharged from the rolling means 1 is discharged toward the conveying means 2 as it is, that is, continuously from the rolling means 1, the conveying means 2 is This is accepted without any delay in the axial direction, which is the conveying direction.

  Incidentally, the horizontal direction in which the rotating shafts 11a, 12a extend here does not mean strict horizontal, but temporarily, the rotating body, for example, the upper rotating body 11 in a state where the material to be reduced W is not limited. This includes the case where the material to be reduced W is tilted to the extent that it cannot move in a so-called skidding state along the upper rotating body 11 when placed on the top.

By the way, in the volume reducing machine according to the present invention, the rotating shaft 11a of the upper rotating body 11 is above the rotating shaft 12a of the lower rotating body 12, and the operator inputs the material to be reduced W into the rolling means 1, That is, the rolling means 1 is eccentric to the near side of the rolling means 1 and tilted to the near side of the rolling means 1.

  As a result, in the rolling means 1, a gap (not shown) between the upper rotating body 11 and the lower rotating body 12 faces diagonally downward on the front side of the rolling means 1. The rotating shaft 11a of the upper rotating body 11 and the rotating shaft 12a of the lower rotating body 12 are arranged in parallel in the horizontal direction. Therefore, a gap between the upper rotating body 11 and the lower rotating body 12 is directly above the rolling means 1. Compared with the case of facing, the supply work to the rolling means 1 by the operator's manual work of the material to be reduced W having a complicated three-dimensional shape before rolling is facilitated.

  That is, when the gap between the upper rotating body 11 and the lower rotating body 12 faces directly above the rolling means 1, the operator who inserts the upper end side of the material to be reduced W into the gap is as follows. Then, the insertion operation is practiced in a state where the material to be reduced W is raised above the head, and the workability is unnecessarily lowered.

  In contrast, in the rolling means 1, when the gap between the upper rotating body 11 and the lower rotating body 12 faces diagonally downward on the front side of the rolling means 1, the inside of the material to be reduced W is rolled. The lower end side of the to-be-reduced material W can be inserted into the gap between the upper rotating body 11 and the lower rotating body 12 in a state of facing the means 1 side. The work of supplying the material to be reduced W to the rolling means 1 by the operator's manual work is facilitated without lifting it unnecessarily high.

  By the way, with respect to the fact that the gap is opposed obliquely downward on the near side of the rolling means 1, as long as it is seen between the upper rotating body 11 and the lower rotating body 12, the rotating shaft 11 a in the upper rotating body 11 is not necessarily limited. However, it can be said that it is not necessary to be eccentric to the front side of the rolling means 1 above the rotating shaft 12a in the lower rotating body 12.

  That is, as shown in the drawing, the upper rotating body 11 and the lower rotating body 12 are supported by the frame 13 with the respective rotating shafts 11a and 12a being pivotally supported. The rotating shaft 11a and the rotating shaft 12a of the lower rotating body 12 are held in a vertical positional relationship.

  As shown in the figure, the frame 13 is placed on the base B1 using a plurality of irregularly shaped correction bases B1a. At this time, the frame 13 itself rolls the upper end by using the correction base B1a. It is inclined toward the front side of the means 1.

  As a result, as long as only the upper rotator 11 and the lower rotator 12 are seen in this state, the rotating shaft 11a in the upper rotator 11 is above the rotating shaft 12a in the lower rotator 12 and on the near side of the rolling means 1. The gap between the upper rotating body 11 and the lower rotating body 12 is made to face diagonally downward on the front side of the rolling means 1.

  From the above, the upper rotating body 11 and the lower rotating body 12 may be pivotally supported in the frame 13 so that the rotary shafts 11a and 12a are vertically positioned. In this case, although not shown, the frame 13 Is tilted to the conveying means 2 side by using the correction table B1a, so that the gap between the upper rotating body 11 and the lower rotating body 12 can be made to face diagonally upward on the front side of the rolling means 1. become.

  And when making the clearance gap between this upper rotary body 11 and the lower rotary body 12 diagonally upward on the near side of the rolling means 1, an operator says the upper end side of the to-be-reduced material W. It can be inserted into the gap between the upper rotator 11 and the lower rotator 12, and the work of supplying the material to be reduced W to the rolling means 1 can also be facilitated by the operator's manual work.

  On the other hand, the specific configurations of the upper rotator 11 and the lower rotator 12 in the present invention will be described below. In the drawing, the upper rotator 11 is formed to have a large diameter with respect to the lower rotator 12. Yes.

  However, from the point of view of the present invention, it is not necessary to make the diameters different between the upper rotating body 11 and the lower rotating body 12, but for example, as described later, the upper rotating body 11 that is one of the rotating bodies is driven. When the rotating body and the lower rotating body 12 which is the other rotating body are driven rotating bodies, a difference in diameter is provided between the upper rotating body 11 and the lower rotating body 12, for example, in a volume reducing machine. It may contribute to weight reduction.

  The upper rotator 11 and the lower rotator 12 are basically formed in a so-called roller shape, but as will be described later, in the upper rotator 11 having the die blade 11b on the outer periphery, as rollers, It is sufficient if it is in the form of a roller when used.

  That is, when the upper rotating body 11 as a roller having the mold blade 11b on the outer periphery is formed as a so-called single object, there is a risk that it takes time to form the mold blade 11b, and the cost of the parts is likely to increase. When the mold blade 11b is partially broken or worn, there is a problem that the whole needs to be replaced.

  On the other hand, although not shown, in the case where the mold blade 11b is formed by providing ribs having an arbitrary shape on the outer periphery of a component formed in a disk shape having an appropriate thickness, a plurality of circles are used. A plate-like component can be connected adjacently to form a roller, and the selected disk-like component can be replaced to cope with partial breakage or wear of the mold blade 11b. That's enough.

  Therefore, from this point of view, in particular, in the upper rotating body 11 shown in the figure, a plurality of disk-shaped constituent members are connected adjacent to each other so as to exhibit a roller mode. The upper rotating body 11 may be composed of a single roller as with the lower rotating body 12 as long as fears and problems can be overlooked.

  Under such a premise, first, the upper rotator 11 and the lower rotator 12 are rotated in opposite directions while maintaining a gap formed between them between 0 mm and 3 mm.

  Although the above-mentioned gap is to be kept between 0 mm and 3 mm, the applicant confirmed that the material to be reduced W having a standard shape passes between the two even if the gap is 0 mm. In some cases, a gap appeared between the two because of mechanical strain, and the passage of the material to be reduced W was allowed.

  On the other hand, when the gap is 3 mm or more, the material to be reduced W having a standard shape also seems to be caused by mechanical distortion when passing between the two, and the rolling becomes insufficient. It was confirmed that the material to be reduced W was not rolled into a preferred plate shape by the restoring force possessed by it.

  From the above, the upper rotator 11 and the lower rotator 12 are rotated in opposite directions while keeping the gap between 0 mm and 3 mm, so that the material to be reduced W is not substantially crushed. Effective rolling with volume reduction processing becomes possible, and the volume reduction body W1 which is the volume reduction material subjected to volume reduction treatment is avoided on the conveying means 2 side while avoiding the loss of the material display on the volume reduction material W. Can be discharged.

  Incidentally, as a measure for keeping the gap between the upper rotating body 11 and the lower rotating body 12 between 0 mm and 3 mm, it is sufficient to use a known mechanism or structure.

  Next, in the upper rotating body 11 and the lower rotating body 12 of the present invention, basically one of them has a mold blade on the outer periphery, while the other has a mold blade on the outer periphery. Without doing it.

  In this embodiment, as shown in FIGS. 2 to 3, the upper rotating body 11 has the mold blade 11b on the outer periphery, and the lower rotating body 12 does not have the mold blade on the outer periphery, Consists of a simple roller to smooth.

  Thus, on the other hand, that is, when the upper rotating body 11 has the mold blade 11b, compared to the lower rotating body 12 that does not have this mold blade on the outer periphery, the slip resistance against the volume member W to be rolled is reduced. Increases, and smooth discharge of the volume reducing body W1 toward the conveying means 2 becomes possible.

  Further, a bumper made of a resin molded body that is a material to be reduced W has many so-called protrusions having various shapes such as reinforcing ribs and connecting parts on the inner side that are not exposed to the outside when the vehicle is mounted, although not shown in detail.

  Therefore, when the volume-reducing material W is rolled and reduced to a preferable substantially plate shape, the above-described protrusion is effectively crushed, and the volume-reduced material W is rolled under this condition to reduce the volume. It is preferable that the above-described mold blade 11b realizes this.

  By the way, since the upper rotating body 11 has a die blade 11b on the outer periphery and enables smooth discharge toward the conveying means 2 of the volume reducing body W1, as long as the lower rotating body 12 is composed of a simple roller, Although it can be said that the upper rotating body 11 and the lower rotating body 12 may be rotated in the same direction as each other, it is possible to implement it because it is not possible to obtain a favorable effect and there is no need to do so. It can be said that the proposal is low.

  On the other hand, in the embodiment shown in the drawing, the upper rotating body 11 has the mold blade functioning as described above. As described above, the rolling means 1 tilts toward the front side of the rolling means. Due to that.

  That is, in this rolling means 1, as described above, the gap between the upper rotating body 11 and the lower rotating body 12 faces diagonally downward on the front side of the rolling means 1.

  As a result, the operator can reduce the volume of the rolling means 1 by inserting the lower end of the bumper into the gap with the inside of the bumper as the volume-reducing material W facing the rolling means 1 as shown in FIG. The material W is supplied.

  From this, in the rolling means 1, the inner side of the bumper faces and contacts the outer periphery of the upper rotating body 11, so that the protrusions such as the ribs and the connecting portions provided inside the bumper are effectively provided. The upper rotating body 11 has the mold blade 11b in order to deform and realize smooth discharge of the volume reducing body W1 to the conveying means 2, which is effective.

  Incidentally, the applicant has confirmed that when the bumper as the material to be reduced W is inserted and operated in the above-described manner, the upper rotating body 11 does not have the mold blade 11b on the outer periphery, and the lower rotating body. When 12 has a die blade on the outer periphery, the protrusions inside the bumper described above were not effectively deformed.

  Further, in the case where a die blade similar to the upper rotator 11 is formed not only on the upper rotator 11 but also on the lower rotator 12, the volume reducing body discharged from the gap between the upper rotator 11 and the lower rotator 12. It was confirmed that W1 fluttered or the mold blades did not collate well and the volume reduction body W1 was broken.

  Further, when supplying the bumper to the rolling means 1, as described above, the lower end of the bumper is placed on the upper rotating body 11 and the lower rotating pair 12 with the inside of the bumper as the material to be reduced W facing the rolling means 1. The volume reducing body W1 that has been rolled and volume-reduced is inserted in the gap between the upper rotating body 11 and the die blade 11b. Tend to bend.

  As for the tendency that the leading end side of the volume reducing body W1 bends upward, it is advantageous when the volume reducing body W1 is discharged by the rolling means 1 so as to be sent out toward the conveying means 2 as compared with the tendency to bend downward. Become.

  This is because, when the tip of the volume reducing body W1 discharged from the rolling means 1 tends to bend downward, a scraper is arranged so as to be close to the outer periphery of the lower rotating body 12, It is necessary to prevent the front end side of the volume reducing body W1 from being wound around the outer periphery of the lower rotating body 12.

  On the other hand, when the leading end side of the volume reducing body W1 discharged from the rolling means 1 tends to bend upward, the leading end side is discharged in a direction in which it is difficult to wind around the outer periphery of the lower rotating body 12, and thus the strength of the scraper is increased. Since it does not require so much, it is advantageous in that a scraper can be manufactured at low cost.

  Furthermore, in the upper rotating body 11 and the lower rotating body 12 of the present invention, basically, one of them is a driving rotating body, and the other is a driven rotating body. That is, in the illustrated embodiment, the upper rotating body 11 is a driving rotating body, while the lower rotating body 12 is a driven rotating body.

  As described above, when the upper rotating body 11 as one drive is a driving rotating body and the lower rotating body 12 as the other is a driven rotating body, both the upper rotating body 11 and the lower rotating body 12 are driven. Compared to the above, the configuration of the drive mechanism 15 (see FIG. 1) can be simplified.

  By the way, as for the shape of the mold blade 11b described above, it may be arbitrarily configured as long as the above-mentioned slip resistance is increased and an effective crushing operation of the protrusion is enabled.

  3 and FIG. 4 are development views partially showing the embodiment of the above-described mold blade 11b. For convenience of explanation, the mold blade 11b is shown in a diagram, but FIG. ), A die blade 11b that can be recognized as a diamond shape or an inclined cross shape is continuously formed on the outer periphery of a single disk-shaped component.

  In the case of the embodiment shown in FIG. 3A, the so-called eyes of the die blade 11b become finer, so that the material to be reduced W is rolled by the rolling means 1 having the upper rotating body 11 in a more plate shape. It will be possible to reduce the volume.

  On the other hand, in the case of the embodiment shown in FIG. 3A, since the so-called fineness of the mold blade 11b is fine, the material to be reduced is reduced by the rolling means 1 provided with the upper rotating body 11 having the mold blade 11b. When rolling W, it is feared that the volume reduction body W1 will break.

  Therefore, if the so-called fineness of the die blade 11b is so fine that the volume reduction body W1 may be broken, the die blade 11b that can be recognized as a rhombus or an inclined cross shape as shown in FIG. 3B is provided. Instead of being formed on the outer periphery of one disk-shaped component, it may be formed between the outer periphery of adjacent disk-shaped components.

  When the die blade 11b has a diamond shape or a slanted cross shape, an acute corner is formed. Similarly, in the case where there is a risk of breakage in the volume reducing body W1, FIG. As in the embodiment shown, a continuous round corrugated die blade 11b having no corners may be used.

  Further, from the viewpoint that the cutting edge 11b does not have corners and is rounded so that breakage in the material to be reduced W during rolling is not a concern, FIG. 4 (A). As shown in the embodiment, the mold blade 11b may be circular.

  Further, in the embodiment shown in FIG. 4 (B), in the embodiment shown in FIG. 3 (C) described above, instead of the mold blade 11b having a continuous round waveform, a continuous angle is provided. The corrugated die blade 11b is formed.

  However, at this time, as in the embodiment of FIG. 3B described above, if the corners are in a butted state, if the breakage in the material to be reduced W during rolling is likely to be a concern, they are adjacent. It may be preferable to shift the position so as not to reveal the corner butt state with the mold blade 11b.

  In the embodiment shown in FIG. 4C, it is assumed that the die blade 11b made of linear ribs orthogonal to the rotation direction is formed at an appropriate interval in the extending direction on the outer periphery of the disk-shaped component.

  In the case of this embodiment, it becomes easy to form the mold blade 11b on the outer periphery of the disk-shaped component material, which contributes to, for example, a reduction in the component cost, and between the adjacent disk-shaped component materials. In the meantime, it is possible to select the position of the mold blade 11b and obtain a preferable rolling effect.

  However, the applicant has confirmed that the die blade 11b is connected in series between adjacent disk-shaped components or the closer to the series, the reduced volume during rolling. When the breakage in the material W is likely to be caused, or when the distance from the mold blade 11b in the rotation direction is unnecessarily large, a preferable rolling effect cannot be obtained.

  As described above, for the mold blade 11b formed on the outer periphery of the upper rotating body 11, an arbitrary shape other than the illustrated one can be selected. However, the cross-sectional shape of the mold blade 11b is, for example, shown in FIG. A form can be proposed.

  First, FIG. 5A shows an embodiment in which the cross section of the mold blade 11b is hemispherical, rectangular, trapezoidal, and triangular from the left in the figure. When the material is rolled into the volume reduction body W1, for example, an arbitrary cross-sectional shape is selected as needed for use in a case where it is desired to positively appear a streak on the inner side surface after rolling.

  In that case, the above-described cross-sectional shape may be used alone or in combination, but in particular, when the cross-sectional shape is a triangle, the cross-sectional shape shown in FIG. As shown in the embodiment, the cross section is a right triangle, and as shown on the left side of the figure, when the vertical plane is positioned in the rotation direction that is leftward in the figure, and as shown on the right side of the figure, By appropriately selecting the case where the vertical surface is positioned in the counter-rotation direction that is directed to the right in the drawing, the formation of the above-described streaks can be effectively practiced.

  Further, regarding the above-described streak having a plurality of lines such as a double line, it is preferable to have a plurality of convex portions or a multi-stage configuration as in the embodiment shown in FIG.

  As described above, while the rolling means 1 is formed, the conveying means 2 is a volume-reduced material that has been reduced in volume by the rolling means 1, that is, a volume-reduced body that has been rolled into a substantially plate shape. The base end side that accepts W1 has a climbing gradient that increases the tip end side that discharges the volume reducing body W1 to the outside, and the base end side appears between the upper rotating body 11 and the lower rotating body 12. It is positioned lower than the height of the gap.

  First, the conveying means 2 is a belt conveyor having an infinite belt (not shown) that is moved by a driving mechanism (not shown). Although not shown, the conveyor means 2 preferably has a rib on the surface of the infinite belt and slides on the volume reducing body W1. It is preferable to increase the resistance to improve the conveyance effect.

  And the belt conveyor which comprises this conveying means 2 is mounted in the upper end of exclusive base B2, and while implementing said climbing gradient, a base end side is between the upper rotary body 11 and the lower rotary body 12. It is designed to be positioned lower than the gap height.

  Next, this transport means 2 has an ascending gradient that makes the tip end side higher than the base end side. This is due to the structure of the stocker means 3 described later. As long as the stocker means 3 is not involved, it is not necessary to have the above-mentioned climbing slope, and conversely, it may be set to have a descending slope.

  And when this conveyance means 2 has a downward slope, it becomes easy to discharge | release the volume reduction body W1 out of this conveyance means 2, Therefore Suppose that the above-mentioned infinite belt consists of a flat belt which does not have a rib on the surface. The cost may be reduced.

  Further, the volume reduction body 1 subjected to volume reduction processing by the rolling means 1 is discharged from the rolling means 1 with its tip raised, and the base end side of the transport means 2 is connected to the upper rotating body 11 and the lower side. It is preferable to be in a state of being surely received so as to be lower than the height position of the gap between the rotating body 12 and the volume reducing body W1 discharged from the rolling means 1 is smoothly moved to the conveying means 2 side. Accepted.

  The belt conveyor as the conveying means 2 is placed on a base B2 having an upper end surface as an inclined surface so as to be arranged at a predetermined height in a predetermined posture. The upper end surface of B2 may be a horizontal plane, and the climbing gradient in the conveying means 2 may be embodied by a lifting mechanism such as a jack having the upper end.

  The stocker unit 3 is a unit that accommodates the volume reduction body W1 that is discharged from the front end of the transport unit 2 with the front end of the transport unit 2 in the vicinity thereof, and is equipped with this so that it can be handled later. Its purpose is to make it easier.

  That is, first, the stocker means 3 has a frame 31 formed in a frame structure having a predetermined mechanical strength and reduced in weight, and the volume reducing body W1 is dropped inside the frame 31. It is formed to accommodate.

  And in this stocker means 3, it is mounted so that the upper end opening of this frame 31 may be straddled on the upper end of the frame 31, and when external force acts, ie, the belt conveyor which comprises the conveyance means 2 It has a slider 32 that moves so as to retreat at the upper end of the frame 31 when pressed by the moving volume reducing body W1.

  On the other hand, the upper end of the frame 31 to which the slider 32 moves has an ascending gradient that lowers the conveying means 2 side while increasing the opposite side, and an external force acting on the slider 32 that has moved to the opposite side is applied. When released, the slider 32 can automatically return to the conveying means 2 side with the gradient and its own weight.

  Therefore, in the stocker means 3, the slider 32 receives the volume reduction body W1 conveyed from the conveyance means 2, and the slider 32 climbs the above gradient so as to allow the volume reduction body W1 to advance. fall back.

  Then, the slider 32 moves backward by the length of the volume reducing body W1, and as a result, the rear end of the volume reducing body W1 is removed from the belt conveyor constituting the conveying means 2 and falls while the front end is left in the slider 32. Thus, the tip is also removed from the slider 32 and dropped into the frame 31 to be accommodated.

  When a plurality of volume reduction bodies W1 are stacked and accommodated in the frame body 31 constituting the stocker means 3, the volume reduction bodies W1 are not completely plate-shaped. Is housed in.

  Therefore, although not shown, a plurality of volume reduction bodies W1 are compressed by a pressing means facing above the frame body 31, and therefore, the compressed state is maintained by, for example, wrapping a band under this state. In this state, for example, it is loaded onto a truck and transferred to a specialized factory.

  As a result, in the illustrated volume reducing machine, the volume reduction material W, which is a resin molded body such as a collected vehicle bumper, is reduced to a substantially plate-like volume reducing body W1, and a truck is used. It is possible to improve the transfer efficiency.

  And the material display is not lost in the reduced volume W1 that has been rolled and reduced in volume to a plate shape, and therefore does not hinder sorting for crushing operations for each material that is practiced in a specialized factory.

  As described above, the volume reduction machine of the present invention is an example in which volume reduction processing is performed using a bumper removed from a vehicle as a resin molded body that may be formed of different materials for each manufacturer as a material to be reduced W. However, from the point of view of the present invention, as long as it is a resin molded body, it is not limited to a bumper, and can be used for volume reduction treatment of other volume-reducing materials W. The effect is not different.

  It is suitable for improving the transfer efficiency such as using a truck by reducing the volume of the material to be reduced, which is a collected resin molded body such as a bumper for vehicles.
