Description

The present invention relates to a compressor suitable for compression of flat and stacked bumpers.

  In recent years, from the viewpoint of protecting the global environment and depleting resources, there has been an increase in the reuse of resources, and resin bumpers mounted on the front and rear of automobile bodies are also recyclable resins. It is desired to recover the lysate and reuse it as a resin product material.

  When collecting bumpers from scrapped vehicles and recycling them, in general, the vehicles are dismantled at a dismantling site, the bumpers are removed, the removed bumpers are transported to a recycling facility, and the bumpers are recycled at the recycling facility. Will do.

  However, because the bumper has a complicated shape, it will be bulky even if it is stacked, etc., so it is difficult to secure a storage place in the demolition processing site, there is a problem that transportation efficiency is bad and transportation cost increases. .

  In order to solve this problem, a bumper volume reduction machine has been proposed in which the bumper is cut into small pieces to reduce the volume during storage and transportation, that is, the volume is reduced (for example, Patent Document 1).

  The conventional bumper volume reduction machine described above is superior in that the volume of the bumper can be greatly reduced because the bumper is made of a fine chip-shaped resin, but the material of the bumper is not uniform. In addition to PP (polypropylene), it is made of various resins such as ABS resin and PU (polyurethane), and is always engraved indicating the material, but after cutting it becomes disjointed and the part with the inscription is another part. Since the material is unknown, the material must be sorted and cut for each material. If the sorting is not thorough, different types of resin will be chipped and mixed after volume reduction of the bumper. Will end up.

  If a recycled material of a different material is mixed with the recycled material at the stage of recycling, there may be a problem that the mechanical properties of the resin product using the recycled material are significantly lowered.

  Therefore, there is no proposal to improve the transport efficiency from the demolition treatment plant to the recycling facility by making the bumper flat and flat so that it does not become bulky even if it is stacked rather than completely chipping the bumper. sell.

  However, the bumper is made of an elastic resin and is generally U-shaped in cross section, and has complicated ribs and protrusions on the inside to compensate for the mounting and strength of the lighting fixture. However, it will not be completely flat, and if stacked, there is still room for compression, and further volume reduction will occur in order to further improve transport efficiency from the demolition treatment plant to the recycling facility.

  Therefore, it is conceivable to stack bumpers and compress them with a compressor (see, for example, Patent Document 2).

Japanese Patent Laid-Open No. 2003-135989 JP 09-327824 A

  However, the shape of the bumper varies depending on the vehicle type, and even if it is flattened, it is not completely flat as described above. Therefore, the height of the bumper is not uniform when stacked, and even if it is compressed by a general press machine In some cases, the compressed state is uneven in the longitudinal direction of the bumper, and the entire bumper cannot be sufficiently compressed.

  In this way, simply compressing the bumper with a press machine does not sufficiently compress the bumper, and there is still room for improvement in bumper transport efficiency, and further reduction of the volume of the bumper is desired. Is done.

  Therefore, the present invention was devised in order to improve the above-described problems, and the object of the present invention is to provide a compressor that can sufficiently compress the stacked bumpers and improve the transport efficiency. Is to provide.

  In order to solve the above-described object, the problem-solving means in the present invention is a compressor that compresses a bumper that is flattened and flattened in a flat plate shape, a base, a column that rises from the base, and a column. It has a slide that can move up and down, and a drive unit that is attached to the support and moves the slide up and down. The drive unit is composed of a six-bar linkage mechanism and a linear actuator that drives the six-bar link mechanism and moves the slide up and down. The six-bar linkage mechanism has a slide as one of the nodes, and includes a slide, a column connecting node connected to the column, an upper left node rotatably connected to one end of the column connecting node, and a column connecting node. An upper right section that is rotatably connected to the other end, a lower left section that is rotatably connected to the upper left section and the slide, and a lower right section that is rotatably connected to the upper right section and the slide. It is characterized by having.

  According to the compressor of the present invention, even if the height of the stacked bumpers is not uniform as a whole, the slide can push down the entire bumper without deviation according to the inclination of the bumper. Efficiency is improved, the bumper is not bulky during transportation, and transportation efficiency can be improved.

  In addition, since bumpers can be stacked with good stacking efficiency, the space for storage in the dismantling treatment facility and the recycling facility can be reduced, and the storage cost can be reduced.

It is a front view of the compressor in one embodiment of the present invention. It is a side view of the compressor in one embodiment of the present invention. It is a perspective view of the stocker which stacks bumpers. It is the figure which showed the process of compressing the bumper stacked by the compressor of one Embodiment. It is a front view of the drive part of the compressor in one modification of one embodiment of the present invention.

  Hereinafter, embodiments of the present invention shown in the drawings will be described. As shown in FIGS. 1 and 2, the compressor 1 according to an embodiment of the present invention includes a base 2, a column 3 that rises from the base 2, a slide 4 that can move up and down with respect to the column 3, It is provided with a drive unit 5 that is attached to the column 3 and moves the slide 4 up and down.

  In the compressor 1, the slide 4 is disposed above the bumper B stacked on the stocker 10, and the slide 4 is pushed downward by the drive unit 5. The bumper B is compressed by sandwiching B.

  As shown in FIG. 3, the stocker 10 includes a bottom portion 10a formed of a rectangular frame on which the bumper B is stacked, a leg 10b suspended from four corners of the bottom portion 10a, and a long side on one side of the bottom portion 10a. U-shaped bumper restraint 10c that is attached to the bumper B and prevents the bumper B from protruding to the side of the stocker 10, and the bumper B that is attached to the other long side of the bottom 10a. The U-shaped bumper restraint 10d that prevents protrusion to the side and a plurality of cross members 10e that are laid across the long side of the bottom 10a, and the compressor 1 is disposed between the bottom 10a and the ground. A gap in which the base 2 can be inserted is formed.

  In addition, although the number of installation of the cross member 10e is arbitrary, it should just be provided so that it can support at least the lower part of the flat bumper B without bending. Further, each of the bottom portion 10a and the cross member 10e uses a square pipe so as to be able to withstand a load when the bumper B, which will be described later, is compressed, and forms a bottom on which the bumper B is stacked. However, a channel material may be used. By using a square pipe or a channel material for the frame 10a and the cross member 10e, it is possible to reduce the weight while satisfying the strength, rather than simply making the bottom 10a a rectangular flat plate.

  The bumper B stacked on the stocker 10 includes, for example, two rollers, and is flattened into a flat plate shape by a volume reducing machine that sandwiches the bumper B inserted between the rollers.

  The base 2 in the compressor 1 is formed by assembling square pipes in an H shape, and wheels 2a are provided at the four corners of the base 2 so as to be movable. And from the base 2, a support column 3 which is also formed of a square pipe rises.

  The slide 4 that directly presses the bumper B includes a pressing frame 4a that is a rectangular frame and is a rectangular frame, and a bracket 4c that is provided above the pressing frame 4a. 3 is supported to be movable up and down.

  In addition, four protrusions 4d formed by square pipes that are laid across the long sides along the short side direction are provided at the lower part of the pressing frame 4a of the slide 4, and the protrusions 4d are provided on the bumper B. The bumper B can be compressed by being pressed against the upper surface of.

  The drive unit 5 includes a six-joint link mechanism 6 and a linear actuator 7 that drives the six-joint link mechanism 6 to move the slide 4 up and down.

  The six-joint link mechanism 6 has a bracket 4c in the slide 4 as one of the joints, and is connected to a support connection joint 6a connected to an arm 3a provided on the support 3 and one end of the support connection joint 6a. A left node 6b, an upper right node 6c rotatably connected to the other end of the column connecting node 6a, a lower left node 6d rotatably connected to the upper left node 6b and the bracket 4c of the slide 4, A lower right node 6e that is rotatably connected to the right node 6b and the bracket 4c of the slide 4 is provided.

  The distance between the rotation fulcrum between the lower left node 6d and the bracket 4c, and the rotation fulcrum between the lower right node 6e and the bracket 4c are the rotation fulcrum between the upper left node 6b and the column connection node 6a, and the upper right node 6c. The distance from the support fulcrum 6a to the rotation fulcrum is set to be the same, and the lengths of the upper left node 6b, the upper right node 6c, the lower left node 6d, and the lower right node 6e are set to the same length. ing.

  The linear actuator 7 is rotatably connected to the rotation fulcrum of the upper left node 6b and the lower left node 6d and the rotation fulcrum of the upper right node 6c and the lower right node 6e. The rotation fulcrum of the lower left node 6d is separated from the rotation fulcrum of the upper right node 6c and the lower right node 6e, and the slide 4 is driven upward, and conversely, by contracting, the upper left node 6b and the lower left node 6d. The slide 4 is driven downward by approaching the rotation fulcrum of the above and the rotation fulcrum of the upper right node 6c and the lower right node 6e. The linear actuator 7 can use a fluid pressure cylinder or an actuator having a motor and a feed screw mechanism, and the mounting is not limited to the above. It is also possible to interpose it rotatably, or to interpose it rotatably between rotation fulcrums that are not adjacent to each other.

  The bracket 4c includes a plurality of channels 4e horizontally mounted on the long side of the pressing frame 4a, a top plate 4f attached to the upper end of the channel 4e, a lower left joint 6d and a lower plate at both ends fixed to the top plate 4f. When the angle between the channel 4g having a U-shaped cross-section to which the right node 6e is hinge-coupled and the lower left node 6d and the channel 4g rising from the top plate 4f becomes a predetermined angle, the lower left node 6d is brought into contact with the lower left node 6d. The left stopper 4h that prevents the joint 6d and the slide 4 from approaching, and the lower right joint 6e comes into contact with the lower right joint 6e when it rises from the top plate 4f and is sandwiched between the lower right joint 6e and the channel 4g. A right stopper 4 i that prevents the joint 6 e and the slide 4 from approaching each other is provided.

  In order to compress the bumper B stacked on the stocker 10 with the compressor 1 configured as described above, the base 2 is moved so as to be inserted below the bottom 10a of the stocker 10 as shown in FIG. The slide 4 is disposed above the bumper B stacked on the stocker 10. Subsequently, the linear actuator 7 is contracted to drive the six-link mechanism 6 and the slide 4 is pushed downward to compress the bumper B.

  As described above, since the drive unit 5 in the compressor 1 is composed of the six-bar linkage mechanism 6 and the linear actuator 7, the linear actuator 7 is contracted and the slide 4 is driven downward to compress the bumper B. In addition, even if the height of the stacked bumper B is low in either the left or right direction in the longitudinal direction and the upper surface of the bumper B is inclined in any one of the longitudinal directions, the slide 4 is moved as shown in FIG. The bumper B can be compressed while inclining following the inclination of B.

  Therefore, according to the compressor 1, even if the height of the bumper B stacked is not uniform as a whole, the slide 4 can push down the entire bumper B without being biased following the inclination of the bumper B. Therefore, the compression efficiency of the bumper B is improved, the bumper B is not bulky during transportation, and the transportation efficiency can be improved.

  In addition, since the bumpers B can be stacked with good stacking efficiency, the space for storage in the dismantling treatment facility and the recycling facility can be reduced, and the storage cost can be reduced.

  If the slope of the bumper B is tight and the compressive force of the slide 4 in the longitudinal direction of the bumper B becomes too large, the bumper B will be pushed out from the side of the stocker 10, but the left stopper 4h Alternatively, since the right stopper 4i limits the inclination of the slide 4, there is no possibility of pushing out the bumper B from the stocker 10.

  In addition, since the plurality of protrusions 4d extending in the short direction are provided in the lower part of the pressing frame 4a, the protrusions are interposed between the pressing frame 4a and the bumper B when the bumper B is compressed by the slide 4. A gap can be formed by the thickness of 4d, and it becomes easy to wind a binding band or a steel wire for binding the bumper B around the bumper B using the gap. In addition, it is good to make a bundling band and a steel wire hit the bottom part 10a of the stocker 10 beforehand, and to stack the bumper B from it.

  During the binding operation, it is necessary to keep the bumper B in a compressed state. Therefore, the linear actuator 7 needs to continuously output thrust, and energy is consumed during that time. The energy consumption in the volume reduction process of the bumper B is increased, and the cost is increased. Therefore, in order to eliminate this waste of energy, a lock mechanism 8 may be provided in the linear actuator 7 as shown in FIG.

  The lock mechanism 8 prevents the separation while allowing the rotation fulcrum of the upper left node 6b and the lower left node 6d and the rotation fulcrum of the upper right node 6c and the lower right node 6e to approach. Comprises a shaft 8a provided at the rotation fulcrum of the upper left node 6b and the lower left node 6d, and an arm 8b rotatably connected to the rotation fulcrum of the upper right node 6c and the lower right node 6e. Yes.

  The arm 8b is provided with a plurality of claws 8c that are hooked on the shaft 8b below, and the claw 8c allows the shaft 8b to pass when the two rotation fulcrums approach each other with the arm 8b engaged. On the contrary, when the two rotation fulcrums are separated from each other, the claw 8c is hooked on the shaft 8b to prevent further separation of the rotation fulcrum. That is, the lock mechanism 8 forms a ratchet mechanism with the shaft 8a and the arm 8b, and when the arm 8b is hung on the shaft 8a, the slide 4 is allowed to descend but is prevented from rising. .

  Thus, if the lock mechanism 8 is provided, even if the drive of the linear actuator 7 is stopped after the bumper B is compressed by the linear actuator 7, the upward movement of the slide 4 is restricted by the lock mechanism 8. Therefore, the bumper B can be maintained in a compressed state, and the binding work of the bumper B can be performed without causing the linear actuator 7 to generate thrust, and the energy consumption is suppressed and the volume of the bumper B is reduced. The required cost can be reduced.

  A shaft 8a is provided at the rotation fulcrum of the upper left node 6b and the lower left node 6d, and the arm 8b is rotatably connected to the rotation fulcrum of the upper right node 6c and the lower right node 6e. The attachment and configuration are not limited to this, and in this six-bar linkage, it is inserted in two arbitrarily selected ones of the nodes, or is rotatably inserted between rotation fulcrums that are not adjacent to each other. May be.

  Furthermore, in the above-described embodiment, the column connection node 6a is fixedly attached to the column 3. However, the column connection node 6a may be slidably attached to the column 3, and the arm 3 and the column connection node 6a are connected to each other. It is also possible to increase the stroke of the slide 4 by installing a linear actuator between them. In this way, in order to increase the stroke of the slide 4, when a separate linear actuator is installed between the arm 3 and the column connection node 6a, a lock mechanism 8 is provided as shown in FIG. Thus, the bumper B can be compressed by the above-described separate linear actuator while the six-bar linkage mechanism 6 is maintained in a locked state without applying a thrust to the linear actuator 7 that drives the six-bar linkage mechanism 6. As a result of securing the stroke of 4, the energy consumption is not sacrificed, and the output of the linear actuator 7 installed in the six-bar linkage mechanism 6 is smaller than the output of the separate linear actuator or because of the lever ratio. The maximum compression force of only the joint link mechanism 6 is smaller than the maximum compression force of the separate linear actuator. Even If you do, it is possible to maintain a six-bar linkage mechanism 6 by the lock mechanism 8 in a locked state, it will be able to compress the bumper B taking advantage of the maximum compression force of a separate linear actuator.

  This is the end of the description of the embodiment of the present invention, but the scope of the present invention is of course not limited to the details shown or described.

  The present invention can be used in a compressor that compresses the bumper B.
