Description

  The present invention relates to a crushing and cutting device for crushing and cutting metal scrap made of a long vehicle having a height, such as a two-story passenger car or a two-story bus, into short scrap pieces.

  The present inventor is suitable for shearing relatively large, long and robust metal scraps, particularly scrap vehicles such as railway vehicles including freight cars and passenger cars or land vehicles including buses and large trucks into a plurality of short scrap pieces. Has already been proposed (see Patent Document 1).

  In this scrap shear, the lateral hydraulic ram is positioned in close proximity to the shear port of the shear and the metal scrap is only for a limited length that is shorter than the overall length of the feed channel. Adapted to reduce the width dimension to less than the internal width of the shear opening, and a pair of lateral hydraulic rams crush the metal scrap loaded into the supply channel from both sides to reduce the width dimension of the metal scrap A lateral hydraulic ram, with the lateral hydraulic ram being associated with a downward hydraulic ram, the downward hydraulic ram being positioned proximate to the shear port.

  At the same time, the metal scrap carried into the supply channel is crushed downward prior to the operation of the pair of side hydraulic rams, and the height of the metal scrap is determined only for the limited length portion by the inner method of the shear port. Adapted to reduce below height, the shear, feeder, side hydraulic ram and downward hydraulic ram drive trains are associated with a central controller that controls the operation in a predetermined sequence of motion.

  This makes it suitable for shearing relatively large, long and robust metal scraps, especially scrap vehicles such as railway vehicles including freight cars and passenger cars or land vehicles including buses and large trucks into a plurality of short scrap pieces. Long and solid metal scrap carried into an open supply channel wider than the shearing port of the shearing machine is fed into the longitudinal direction of the supply channel by a downward hydraulic ram and a lateral hydraulic ram attached to the supply channel. Only a limited length portion that is shorter than the total length of is compressed to a cross-sectional area less than the internal dimension of the shear port.

  Therefore, the driving torque of these hydraulic rams is clearly reduced compared to the case of the scrap shearing machine according to the prior art, and it can be driven by a relatively small hydraulic power cylinder. Each drive system of the shearing machine, feeder machine, lateral hydraulic ram and downward hydraulic ram is controlled by a general control device in a predetermined operation sequence, so that the shearing machine efficiently removes a plurality of short scrap pieces from metal scrap. These short scrap pieces can be transported to a recycling facility for sorting and collection of resource materials.

  According to a fourth aspect of the present invention, there is provided a vehicular crushing device, wherein the crushing means according to any one of the first to third aspects is a long metal that is crushed to a first height position by the crushing roller. A downward hydraulic ram that crushes the scrap to a predetermined second height position that can be cut by the cutting means is further provided.

  According to a fifth aspect of the present invention, there is provided a vehicular crushing device according to any one of the first to fourth aspects, wherein a metal scrap cutting means port is provided on a wall surface of the side wall portion defining the inner width of the supply channel. It is characterized in that it is provided with a large number of transporting roller groups that assist in transporting to.

  The present invention relates to a crush cutting for a vehicle that cuts a relatively large, long and robust metal scrap, particularly a railway vehicle including a freight car and a passenger car, or a waste vehicle such as a land vehicle including a bus and a large truck into a plurality of short scrap pieces. In particular, there is an effect that it is possible to obtain a crushing and cutting device for a vehicle that crushes a long vehicle having a height such as a two-story passenger car or a two-story bus and cuts it into short scrap pieces. .

It is a side view explaining the composition of one example of the crushing cutting device for vehicles of the present invention. It is a top view of FIG. It is a front view of FIG. It is AA sectional drawing of FIG.

  In the present invention, there is provided a vehicle crushing and cutting device for cutting a long metal scrap including a vehicle into a plurality of short scrap pieces, and a floor portion on which the long metal scrap is conveyed, and the floor A supply channel having a side wall portion that prevents the metal scrap that is erected and conveyed opposite to the rule of the part from escaping to the outside, and a long metal scrap that is conveyed through the supply channel are predetermined from above. A crushing and cutting device for a vehicle, comprising: a crushing means that crushes to a height position; and a cutting means that cuts a long metal scrap that has been crushed to a predetermined height position by the crushing means into a plurality of short scrap pieces. 1, one or more crushing rollers for crushing the upper part of the long metal scrap are provided as crushing means. As a result, it is possible to obtain a crushing and cutting apparatus for a vehicle that crushes a long vehicle having a height such as a two-story passenger car or a two-story bus with a crushing roller and cuts it into short scrap pieces.

  As the crushing roller of the present invention, any crushing roller may be used as long as it crushes the height position of the long metal scrap, and the crushing roller is arranged above the supply channel and rotates and crushes when the supply channel is conveyed. Can be mentioned. As a matter of course, the direction of the rotation shaft of the crushing roller is arranged in a direction orthogonal to the conveying direction of the metal scrap. In addition, since the rotation direction is rotated downward from the point of contact with the metal scrap, it functions as feeder means for conveying the metal scrap in a direction with the cutting means while crushing the long metal scrap.

  As a preferable aspect of the crushing roller of the present invention, a protrusion or a protrusion piece is erected on the side surface of the roller. This makes it easy to bite under the crushing roller when crushing the metal scrap of a long, long vehicle for the first time, and the protrusions and pieces of the bite can bite into the metal scrap or pierce it. Become. When the metal scrap is a long vehicle, the place where the crushing roller first contacts is the ceiling portion. Railway vehicles including freight cars and passenger cars, and land vehicles including buses and large trucks have a floor portion that is made stronger than a ceiling portion. For this reason, the upper part of the metal scrap is easily crushed and crushed by the biting of the protrusions and the piercing of the protruding piece, so that the crushing by the subsequent further crushing roller and the crushing by other crushing means can be easily performed. Is possible.

  Therefore, the crushing roller having protrusions or protruding pieces standing on the side surface of the roller should be arranged as the first crushing roller of one or more crushing rollers, and moreover, one or more crushing rollers. A protrusion or a protrusion piece may be erected on all of the crushing rollers.

  As a further preferable aspect of the crushing roller of the present invention, a plurality of the long metal scraps to be supplied are arranged so as to crush in a stepwise manner. As a result, the crushing roller having a large diameter is gradually crushed without being driven by the driving means having a large output, so that a plurality of crushing rollers driven by the driving means having a small output can be used.

  Although it is possible to crush to a height that can be cut by the cutting means by a plurality of crushing rollers arranged in stages, it may be crushed to a height that can be cut by the cutting means with a downward hydraulic ram. That is, as the crushing means, a downward hydraulic ram is further provided that crushes the long metal scrap that has been crushed to the first height position by the crushing roller to a predetermined second height position that can be cut by the cutting means. . As a result, the crushing with the hydraulic ram becomes a more solid crushing block than the crushing with the crushing roller, so that the process of making a short scrap with the subsequent cutting means can be performed well.

  That is, the crushing by the crushing roller is due to the rotation of the roller, so that the metal scrap with which the roller abuts is gradually crushed. On the other hand, in the crushing by the hydraulic ram, the crushing is performed up and down every block. Therefore, the crushing of the hydraulic ram that crushes up and down every block is larger than the crushing roller due to the crushing of the scrap in the front-rear direction. For this reason, since the crushing block by a hydraulic ram becomes firmer, the process of making a short scrap with a subsequent cutting means can be performed satisfactorily.

  Therefore, as a preferable aspect of the crushing means of the present invention, the long metal scrap that has been crushed to the first height position by the crushing roller is crushed to a predetermined second height position that can be cut by the cutting means. And a downward hydraulic ram.

  The downward hydraulic ram of the present invention is positioned close to the cutting port of the cutting means, and the metal scrap that is carried in the supply channel and is crushed to the first height position by the crushing roller is placed below the hydraulic ram. After loading, the metal scrap is crushed downward to crush and reduce the height position of the metal scrap to a predetermined second height position that is less than the inner height of the cutting port of the cutting means. As long as it is adapted.

  The cutting means of the present invention may be any means as long as it can cut a crushed long metal scrap into short pieces, such as cutting with a rotating rotary blade driven by rotation or cutting with a jet water stream including abrasive. A guillotine type straight blade having a fixed lower cutter blade, an upper cutter blade that shears the metal scrap in cooperation with the lower cutter blade, and a hydraulic stamper that presses and clamps the metal scrap downward The cutting by hydraulic drive is more preferable because the configuration is simplified and maintenance is easy.

  More specifically, it has a passage formed in a portal-shaped airframe frame, the entrance of this passage forms a cut opening that opens at one end face of the supply channel, and the exit on the opposite side is a short length after cutting. Open to pit to accept scrap pieces. In the middle of this passage, a hydraulic stamper driven by a hydraulic cylinder to clamp and scrap metal scrap downward before the cutter at the time of cutting, and a lower cutter fixedly arranged on the outlet side adjacent to this hydraulic stamper Examples include a blade, an upper cutter blade that cuts metal scrap into short scrap pieces in cooperation with the lower cutter blade, and a main hydraulic cylinder for driving the upper cutter blade.

  The supply channel according to the present invention includes a floor portion on which a long metal scrap is conveyed, and a side wall portion which stands and opposes both rules of the floor portion and does not escape to the outside. Any channel may be used as long as it has a U-shaped cross section. Note that the metal scrap may be satisfactorily crushed by crushing with a crushing roll or a downward hydraulic ram, and may be made of a strong constituent material such as compressed concrete so as not to escape from the side wall.

  As a preferred embodiment, a plurality of transporting roller groups for assisting transport of the metal scrap to the shearing means port are provided on the wall surface of the side wall portion that defines the inner width of the supply channel. Thereby, the long metal scrap which is crushed by the crushing roller is favorably conveyed toward the cutting means.

  The internal width of the supply channel is equal to or less than the internal width of the cutting port of the cutting means, so that both side walls of the metal scrap are crushed by the crushing roller or the downward hydraulic ram during cutting. Therefore, it can be easily cut into short pieces.

  FIG. 1 is a side view for explaining the configuration of an embodiment of a crushing and cutting device for a vehicle according to the present invention. FIG. 2 is a plan view of FIG. FIG. 3 is a front view of FIG. 4 is a cross-sectional view taken along the line AA in FIG. As shown in the figure, the crushing and cutting device 10 for a vehicle according to the present embodiment is a floor having an internal width that is the same as or slightly narrower than the internal width of the guillotine type straight blade cutting machine 20 and the shearing port 22 of the cutting machine 20. A supply channel 30 that forms a rectangular parallelepiped space is provided by the portion 31 and the side wall portions 32 and 33 that prevent the metal scrap that is erected and conveyed opposite to the rules of the floor portion from escaping. On the inner surfaces of the side wall portions 32 and 33, a large number of conveying roller groups 34 that assist the conveyance of the metal scrap are formed.

  Between the shearing machine 20 and the supply channel 30, it has the same width as the inner width of the supply channel 30, and the shear port of the shearing machine 20 from a first height position slightly lower than the highest height position of the ram. A downward hydraulic ram 40 is provided as a crushing means for crushing the metal scrap at a second height position equal to or less than 22 inner heights.

  Above the supply channel 30, three crushing rollers 50, 54, and 58 are installed as another crushing means with the installation height lowered stepwise. The directions of the rotation shafts 52, 55, 59 of the individual crushing rollers 50, 54, 58 are arranged in a direction orthogonal to the conveying direction in the supply channel 30 of the metal scrap 35.

  The metal scrap 35 transported in the supply channel 30 is rotated by a motor (not shown) so as to transport in the direction of the shear port 22. A plurality of protrusions 51 arranged in parallel to the longitudinal direction are formed on the side wall surface of the first crushing roller 50 arranged at the highest height, and the metal scrap of a tall vehicle with a high height is formed. Is easily squeezed under the roller 50 when crushing for the first time.

  Note that the protrusion 51 may be a large number of protrusions that have a large number of holes when the metal scrap 35 is a long vehicle. Further, the crushing roller provided with the protrusion 51 or the crushing roller provided with the protruding piece may be disposed not only on the first crushing roller 50 but also on the second crushing roller 54 and subsequent rollers.

  Since the metal scrap 35 crushed by the first crushing roller 50 is rotated downward from the time of contact by the rotation of the roller 50, the long metal scrap 35 is crushed while the height position is crushed smaller. The scrap 35 is conveyed toward the second crushing roller 54. That is, the rotation of the first crushing roller 50 functions as feeder means.

  The metal scrap 35 that has reached the second crushing roller 54 is crushed by the rotation of the second crushing roller 54 in the same manner as the first crushing roller 50, and the metal scrap 35 is crushed toward the third crushing roller 58. It is conveyed to. That is, the rotation of the second crushing roller 54 also functions as feeder means.

  The metal scrap 35 that has reached the third crushing roller 58 is crushed to the first height position where the height position is smaller by the rotation of the third crushing roller 58 in the same manner as the second crushing roller 54. It is conveyed downward in the downward hydraulic ram 40. That is, the rotation of the third crushing roller 58 also functions as feeder means.

  The long metal scrap 35 that has passed below the downward hydraulic ram 40 maintained in a state higher than the first height position is an upper wall surface portion that constitutes the shear port 22 immediately before the shear port 22 of the shearing machine 20. Stop. In this state, the downward hydraulic ram 40 is driven, and the loaded metal scrap 35 is crushed downward so that the height dimension of the metal scrap 35 is limited to the first height less than the internal height of the shearing port 22 only for a limited length portion. Reduce to 2 height position.

  This crushing and cutting device 10 for a vehicle is a relatively large, long and robust metal scrap, particularly a railway vehicle including a freight car and a passenger car or a disposal vehicle such as a land vehicle including a bus and a large truck, into a plurality of short scrap pieces. Suitable for cutting. These metal scraps are preferably free from non-metallic parts before being loaded into the supply channel 30. For example, in an abandoned car, sheets, interior materials, tires, glass, plastic bumpers and dashboards made of cloth, seat covers, and urethane foam are removed. These non-metals are separated by peeling off from the vehicle body. Moreover, even if it is a metal, it is preferable that the components comprised with spring steel are removed beforehand so that an excessive load may not act on the drive source of the downward hydraulic ram 40.

  The straight blade cutting machine 20 has a passage formed in a portal-shaped fuselage frame 21, and the entrance of this passage forms a cutting opening 22 that opens at one end face of the supply channel 30, and the outlet on the opposite side thereof is cutting. An opening is made in the pit 28 for receiving a later short scrap piece. In the middle of this passage, a hydraulic stamper 24 driven by a hydraulic cylinder 23 to clamp and scrap metal scrap downward before the cutter at the time of cutting, and fixedly arranged on the outlet side adjacent to the hydraulic stamper 24 A lower cutter blade 25, an upper cutter blade 26 for cutting metal scrap into short scrap pieces 36 in cooperation with the lower cutter blade 25, and a main hydraulic cylinder 27 for driving the upper cutter blade 26. ing.

  The short scrap piece 36 cut by the straight blade cutting machine 20 falls into a pit 28 provided adjacent to the outlet of the straight blade cutting machine 20 and is temporarily stored. Since the bottom surface of the pit 28 is at a lower position than the lower cutter blade of the straight blade cutting machine 20 and is inclined so as to gradually become deeper as the distance from the cutting machine increases, the cut short scrap pieces 36 are contained in the pit 28. Thus, it moves by itself from the immediate vicinity of the cutting machine 20 and does not stay near the exit of the cutting machine.

  The supply channel 30 is completely opened upward except in the region where the downward hydraulic ram 40 is disposed, and when the downward hydraulic ram is in the raised position (initial position), the lower space is also opened. The downward hydraulic ram 40 is driven by a hydraulic cylinder 42. The downward hydraulic ram 40 and the hydraulic cylinder 42 are supported by a portal frame 41 disposed so as to straddle both side walls of the supply channel 30. The downward hydraulic ram 40 has the same width dimension as the inner width of the supply channel 30.

  The drive source of the hydraulic cylinder 23 and the main hydraulic cylinder 27 of the straight blade cutting machine 20, the hydraulic cylinder 42 for the downward hydraulic ram 40, and the rotation of the crushing rollers 50, 54, 58 are controlled by a sequence controller or the like. It suffices if the operation is controlled.
