Description

  The present invention relates to a scrap processing yard suitable for dismantling / breaking / sorting various scraps such as automobiles.

  With the rapid development of automobiles in recent years, the number of scrapped cars is also increasing dramatically. In addition, recent automobiles use many composite parts made of various materials, so they are being dismantled. Sorting work by material for each part is becoming extremely complicated. In addition, at present, sales companies are obligated to collect waste products from household electrical appliances, and how to make them into renewable resources is an important issue.

  In addition, conventional scrap demolition work is generally handled exclusively for automobile scrap in order to improve scrap car dismantling work.For example, other scrap dismantling such as household appliances and building waste was excluded from normal handling. Various kinds of scraps are accumulated and waiting for dismantling.

  Among various types of scrap, for example, dissimilar metal parts to be separated and collected, such as pipe parts and valve parts, such as water distribution pipe scraps, are small, hard, and firmly fixed. Since many things cannot be handled by conventional dismantling vehicles, in many cases they were disposed without separate collection. In this case, the pipe part is relatively inexpensive iron scrap, the valve part is relatively expensive gunmetal, etc., and if it is collected separately, an economic effect can be obtained. Etc. are wasted.

  Furthermore, for scraps such as electric washing machines, the outer casing and washing tub must be separated from the internal motor, and the electric refrigerator must also be separated from the casing, inner insulation and compressor. However, in conventional dismantling vehicles, the electric motors and compressors inside the boom cannot be removed directly with the opening and closing tool at the end of the boom, and other manual dismantling or unavoidably disposing of the unit is performed. It was broken.

  The applicant reduces the occurrence of an accident to a live worker due to scrap or machine during dismantling and / or breaking and / or sorting work as much as possible, and efficiently transports, disassembles and / or breaks and / or sorting. In addition, a scrap processing yard that can improve the quality of sorted scrap has already been proposed (see Patent Document 1).

As this scrap processing yard, an installation loader that is installed in the vicinity of the unloading position on the periphery of the fixed stage that is raised with respect to the traveling path on which the transport vehicle travels, and that unloads the scrap from the transport vehicle and the installation loader And a shear which is installed on or adjacent to the stage in the arm working area and cuts off the unloaded scrap, and a self-propelled dismantling work vehicle is disposed on the stage to dismantle and / or break the scrap. And / or a plurality of work areas for sorting.
JP 2002-128280 A

  The above-mentioned scrap disposal yard can efficiently transport, dismantle and / or break and / or separate by reducing the occurrence of an accident to a live worker as much as possible. However, as the recycling movement has become active, scraps transported to the yard are not only automobile waste, but also various types of scrap are mixed due to diversification of building waste including rebars, steel frames, electric wires, etc. When doing so, it may be inefficient to dismantle and / or break and / or separate these scraps.

  An object of this invention is to obtain the scrap processing yard which can disassemble and / or fracture | rupture and / or separate scrap more efficiently.

The stage type scrap processing yard according to the invention described in claim 1 is provided around a stage for disassembling and / or separating the scrap carried by the transport vehicle and as a passage for the transport vehicle. To the stage for unloading the loaded scrap on the stage and / or unloading the processed scrap to the transport vehicle with respect to the vehicle travel path having a paved road surface and the transport vehicle parked in the stop section of the vehicle travel path In a stage-type scrap processing yard provided with an installed installation type crane apparatus and an installation type scrap cutting apparatus attached to the stage within the work range of the installation type crane apparatus,
The upper surface of the stage constitutes a scrap processing work floor whose height is higher than the area around the stage including the road surface of the vehicle traveling path,
At least one self-propelled multifunctional demolition work machine is placed on the scrap processing work floor,
A plurality of sets of installation type machines each including an installation type crane apparatus and an installation type scrap cutting apparatus are provided.

  The stage type scrap processing yard according to the invention described in claim 2 is characterized in that the scrap cutting device of at least one set of installation type machines according to claim 1 is different from the scrap cutting device of another set of installation type machines. It is characterized by having.

  A stage type scrap processing yard according to the invention described in claim 3 is characterized in that at least one set of installation type machines according to claim 1 or 2 is arranged in another set with a common work area on the scrap processing work floor in between. It is arranged to face the stationary machine.

  The present invention has an effect that scraps can be efficiently dismantled and / or broken and / or separated even when various scraps such as automobile waste, building waste, and home appliance waste are mixed.

  In the present invention, a stage for dismantling and / or sorting the scraps carried by the transport vehicle, a vehicle travel path having a paved road surface provided around the stage as a traffic path for the transport vehicle, and vehicle travel An installation type crane apparatus attached to the stage for unloading the loaded scrap on the stage and / or unloading the processed scrap to the conveyance vehicle with respect to the conveyance vehicle stopped at the stop section of the road, and an installation type crane In a stage-type scrap processing yard equipped with an installation-type scrap cutting device attached to a stage within the work range of the apparatus, the scrap processing work in which the upper surface of the stage is higher than the area around the stage including the road surface of the vehicle traveling path A floor is constructed, and at least one self-propelled multifunctional dismantling machine is arranged on the scrap processing work floor. Each plurality of sets of mounting type machines that the the mounting crane apparatus and installation type scrap cutting device and a set is provided. Thereby, even when various scraps are mixed, scraps can be efficiently disassembled and / or broken and / or separated.

  That is, in the scrap processing yard of the present invention, the upper surface of the stage forms a scrap processing work floor whose height is higher than the area around the stage including the road surface of the vehicle traveling path, and the upper surface of the work floor has a flat work area. Including. Thus, since the scrap processing work floor is formed at a high position with respect to the travel path on which the transport vehicle travels, the transport vehicle into which the operator of the self-propelled multifunctional dismantling work machine on the stage is next carried It is possible to visually observe the scrap in the packing box as viewed from above, and to efficiently perform scrap disassembly and / or fracture and / or sorting. In addition, since scrap pieces generated in scrap scrapping and / or breaking and / or sorting operations are difficult to be left on the travel path, there is an advantage that a puncture accident of the transport vehicle is less likely to occur.

  The specific height from the surrounding area of the scrap processing work floor may be a height that allows the operator of the self-propelled multifunctional dismantling work machine to look down on the inside of the cargo box of the transport vehicle, preferably 1 to 3 m, preferably A height of about 2 m is preferred. In addition, the side surface of the stage around the work floor preferably forms a substantially vertical wall surface that stands up from the periphery. This prevents a live worker from entering the scrap processing work floor inadvertently, and prevents an accident for the live worker.

  Further, the periphery of the stage is paved as the traveling road surface of the transport vehicle. This is because the transport vehicle transports a large amount of scrap, and the traveling road surface must support a large weight including the weight of the transport vehicle. The traveling road surface may be provided around the stage, and may be provided not only on the entire circumference of the stage but also on a part of the periphery of the stage as long as parking places for unloading to the stage and unloading from the stage are included. In the present invention, “unloading” refers to carrying the scrap onto the stage, and “unloading” refers to loading the scrap that has been separated and disassembled from the stage onto the transport vehicle.

  In addition, for example, parking / parking sections, vehicle traveling directions, entry prohibition, and the like can be set on the traveling road surface by signs and signs, and in some cases, a one-way road that goes around the stage can be set. For example, in order to make the width of the unloading position travel path wider than the width of other travel paths, the travel path where the unloading position exists is divided into two lanes, or the plane shape of the unloading position of the stage is set as a recess and the following transport vehicle A stop space may be provided to allow overtaking. In addition, when unloading scrap that has been separated and dismantled from the stage to the cargo box of the transport vehicle, the transport vehicle may be stopped at the unloading position and unloaded to the cargo box, or a separate load may be provided. Unloading may be performed at the unloading position.

  In addition, when a one-way road that circulates around the stage is set, there is little traffic jam according to the travel path for traveling only in a predetermined direction, and the transport vehicle can reach the unloading position in a short time, and Unloading is carried out smoothly mainly by a stationary crane device, and the transport vehicle that has finished unloading has the advantage that it can start without traffic jams by a traveling path for traveling only in a predetermined direction.

  In the present invention, the scrap is unloaded and temporarily stored on a scrap processing work floor, which is prohibited from being entered by a live worker, by means of a stationary crane device or a boom tip pen on a self-propelled multi-function dismantling machine. The The scrap on the scrap processing work floor is dismantled and / or broken and / or separated by at least one, more preferably several self-propelled multifunctional dismantling machines. For example, in the case of scrapped automobiles, when disassembling and breaking, depending on the material such as non-ferrous metals such as iron and aluminum, plastic and rubber, the location and form of each material Is determined to some extent regardless of the vehicle type, and the amount is also determined to some extent. However, because there are many types of building waste and household appliance waste, when the operator of the self-propelled multifunctional dismantling machine disassembles and breaks the waste, the internal structure is confirmed. It was necessary to separate nonferrous metals such as iron and aluminum, plastics, rubber, and other materials.

For example, in construction waste such as large-scale houses such as condominiums, the distribution lines that distribute electricity to each house are high-quality copper resources, aluminum sash frames are aluminum resources, reinforcing bars and pipes in reinforced concrete are iron resources, and concrete fragments Can be reused as gravel for road paving. In particular, the distribution lines of large-scale houses are thick and have a cross-sectional area of 400 mm ² (stranded wire), and the material is high-quality copper. The piping part is relatively inexpensive iron scrap, and the valve part is a relatively expensive gun metal. Furthermore, in the waste of large household appliances such as an electric washing machine, the outer casing and washing tub must be separated and disassembled from the electric motor inside.

  In order to achieve more efficient scrap disassembly and / or breakage and / or sorting work by diversifying scraps for the purpose of recycling as described above, in the stage type scrap processing yard of the present invention, as a preferable aspect, A plurality of sets of installation type machines, each of which includes a set type crane apparatus and a set type scrap cutting apparatus, and a scrap cutting apparatus for at least one set of setting type machines is a scrap cutting apparatus for another set of setting type machines And have different cutting ability. Thereby, even in the diversification of scraps, scraps can be efficiently disassembled and / or broken and / or separated.

  As a preferred embodiment of the present invention, the at least one stationary scrap cutting device may have a cutting ability different from other stationary scrap cutting devices. High cutting ability includes long cutting length of the cutting blade of the cutting device so that it can handle cutting of large waste materials, high cutting force with high output of the cutting blade, etc. However, it is preferable that the cutting force is increased by setting the pressing force of the cutting blade to a high output. That is, if the cutting blade of one cutting device is a high-power installation type scrap cutting device capable of cutting a steel frame, the other cutting device has a low output capable of cutting a thin steel plate. With a cutting device that can cut large waste, it is impossible to cut small scrap. This is due to the structure of the cutting blade. Specifically, in a high-power cutting device, a gap is formed on the sliding surface of the shearing blade in order to improve the shearing force of the cutting blade. For this reason, although a large waste material can be cut | disconnected, in a thin waste material and a small waste material, waste material enters into the formed gap | interval, and cutting becomes impossible. For this reason, even if the scrap is diversified, it may be sorted while sorting between a high-power cutting device having a high cutting ability and a low-power cutting device. As a result, the diversified scrap can be efficiently disassembled and / or broken and / or separated, and the quality of the separated scrap can be improved.

  There may be two or more sets of the installed crane apparatus and the installed scrap cutting apparatus of the present invention on the scrap processing work floor or adjacent to the scrap processing work floor. Rather than disposing them close to each other on the scrap processing work floor, each disposition type scrap cutting according to the material of the scrap while disassembling, breaking and sorting is performed. By making it close to the device position, it can be processed efficiently. Therefore, as a preferable aspect, at least one set of stationary machines is arranged to face another set of stationary machines with a common work area on the scrap processing work floor in between.

  In addition, as an installation type crane apparatus of this invention, it installs in the vicinity of the unloading position of the periphery of a scrap processing work floor, and unloads a scrap on a scrap processing work floor from a conveyance vehicle or out of a scrap processing work floor. What is necessary is just to be sufficient, for example, it can comprise with the loader crane provided with the boom which can be turned up and down. You can select a boom tip with a grapple attachment to grip the scrap or a lifting magnet attachment if the scrap is iron.

  As the self-propelled multifunctional dismantling work machine of the present invention, it suffices that at least one self-propelled multifunctional dismantling work machine is disposed on the scrap processing work floor, and can be appropriately selected according to the type of the unloaded scrap. For example, scraps that do not require separation of non-ferrous metals, such as automobile chassis, are mounted on the body of a self-propelled vehicle so as to be able to undulate and turn in order to efficiently dismantle and / or break. A self-propelled multi-function dismantling work machine including a hydraulic operation boom and an opening / closing operation tool such as a scrap dismantling penetrator attached to the tip of the boom is disposed in a work area on the scrap processing work floor.

  In order to improve work efficiency, the above-mentioned self-propelled multifunctional dismantling machine is equipped with a pair of left and right arms that can be raised and lowered, mounted on the front or rear of the vehicle body, and attached to each of these arms. A multi-type self-propelled multi-function dismantling work machine further provided with a holding tool for holding the scrap target object between the arms may be arranged for each of a plurality of work areas. In addition, if it is a self-propelled multi-function dismantling machine equipped with a cutting rod means for cutting a scrap object at a position near the arm pivot fulcrum of a pair of left and right work arms, it becomes easy to cut long waste material. In addition to being used for scrap scrapping work of scrap automobiles, it is particularly effective for sorting and scrapping construction waste and piping waste, and scrap can be efficiently scrapped and / or broken and / or separated. This also leads to improved quality of scrap.

  In addition, for scraps that require separation of non-ferrous metals, such as automobile engines, self-propelled type equipped with lifting magnets as work tools in order to efficiently disassemble and / or break and / or separate A multi-function dismantling work machine is placed in the work area. About the work vehicle provided with this lifting magnet, even if it is a single work vehicle, it is good also as one of the tools which can be attached or detached of the above-mentioned multi type self-propelled multifunctional dismantling work machine.

  The planar shape of the stage or the scrap processing work floor of the present invention is not limited to a rectangular shape, and may take any shape. For example, it may be a planar shape such as a circular shape or an L shape.

  In addition, for the work area described above, an area on the stage only needs to be determined for each of a plurality of self-propelled multi-function dismantling work machines. It is not prohibited to include overlapping areas on work machines. Rather, in order to deliver scrap, it is also possible to provide scrap delivery means such as a transport vehicle, a transfer conveyor, and a lifter that move between these work areas in order to deliver scrap between remote work areas.

  The scraps that have been unloaded, sorted, cut, crushed and sorted are cut by an installed scrap cutter installed on or adjacent to the stage in the arm work area of the installed crane apparatus. If the scrap transported by the transport vehicle is all made of iron, it is inserted directly from the transport vehicle into the input port of the installed scrap cutting device by the installed crane device, and cut into a predetermined size without delay. What is necessary is just to carry on the load box of another conveyance vehicle with an installation type crane apparatus.

  FIG. 1 is an explanatory view illustrating the configuration of an embodiment of a stage type scrap processing yard according to the present invention. FIG. 2 is an explanatory diagram showing a planar configuration of the scrap processing yard of FIG. As shown in the figure, the stage-type scrap processing yard 1 includes a scrap processing work floor 3 having a rectangular planar shape installed at a position 2 m higher than the traveling path 2 on which the surrounding transport vehicle 20 travels.

  In the vicinity of the unloading positions 4a and 2b provided side by side on one side of the rectangular scrap processing work floor 3, installation loaders 5a and 5b are erected on the bases 6a and 6b as installation cranes, respectively. The support pillars 7a and 7b are rotatably installed. Guillotine shears 12a, 12b as scrap cutting machines are arranged on the far side of the opposing positions of the installation loaders 5a, b. A grapple attachment 9 for unloading the scrap 10 transported by the transporting vehicle 20 is provided at the tip of the arm 8b connected to the prone boom 8a of the loader 5a, b. The scrap 10 is transferred to the inlets 13a, b of b. The grapple attachment 9 of the installation loaders 5a and 5b may be a lifting magnet attachment depending on the scrap 10.

  Of the two guillotine shears 12a and 12b, at least one guillotine shear 12a has a cutting ability different from other guillotine shears 12b. That is, the cutting output of the guillotine shear 12b was made smaller than the cutting output of the guillotine shear 12a. As a result, thick and hard items such as automobile chassis frames and steel frames of building waste are cut with a guillotine shear 12a having a large cutting output, and relatively thin items such as steel plates of steel bodies, reinforcing bars, aluminum frames of sash frames, etc. For thin and soft objects, scraps can be efficiently dismantled and / or broken and / or broken by moving them to the periphery of each shear while selecting them by scrapping and separating work so that they are cut by a guillotine shear 12b with a small cutting output. Can be separated. In addition, since one of the two guillotine shears can have a small cutting ability, there is an advantage that the equipment cost can be reduced.

  The unloading transport vehicle 20 returns from the processing yard 1 through the traveling path 2 around the scrap processing work floor 3. At this time, since the traveling road 2 is one-way, it can leave the yard 1 without traffic jam.

  On the scrap processing work floor 3, a hydraulic operation boom 15 having an opening / closing work tool 14 for sandwiching scrap or removing non-ferrous metals and plastics at the tip and a pair of left and right arms 17 provided with a sandwiching tool 16 are provided on the vehicle. Multi-type self-propelled demolition work vehicles 18a to 18e are arranged as five self-propelled multi-function demolition work machines provided at the front or rear. Each self-propelled dismantling work vehicle 18a-e has a work area 19a-e defined for each worker. Instead of the multi-type self-propelled demolition work vehicle, a riffmag self-propelled demolition work vehicle having a backhoe with a lifting magnet capable of magnetically attracting iron metal may be arranged.

  Further, as the self-propelled dismantling work vehicles 18a to 18e, a pair of cutting blade pivot support shafts that are pivotally connected to the vehicle main body at one end near the arm fulcrum of the pair of left and right arms 17, respectively. One provided with cutting scissor means including a pair of link levers that pivotably connect each other end of each scissors blade and each of the pair of work arms is arranged. As a result, it becomes easy to cut long waste materials and is used not only for scrap scrapping work of scrapped automobiles, but also particularly effective for separating and scrapping construction waste materials and pipe waste materials, and efficiently scraping and / or scraping. It is possible to break and / or sort, and to improve the quality of the separated scrap.

  Of the five self-propelled demolition work vehicles 18a to 18e, four self-propelled demolition work vehicles 18a to 18d including two unloading positions as work areas are each independently or jointly installed with an installation loader and other demolition work vehicles. Then, the scrap 10 is unloaded from the transport vehicle 20. The scrap 10 to be unloaded is dismantled, broken, or sorted in each work area alone or jointly in overlapping work areas. It should be noted that only the self-propelled demolition work vehicles 18a to 18e can move on the scrap processing work floor 3 including the respective work areas, and the workers are determined not to be able to enter by themselves.

  Due to the above configuration, the following advantages are obtained. First, the transport vehicle 20 enters in one way for unloading, and can efficiently carry scrap by unloading with each loader or the like at one of two unloading positions according to the type of scrap of the load. it can. The unloaded scrap is cut with a guillotine shear with different cutting ability, or is disassembled, broken, and sorted with a self-propelled dismantling work vehicle 18a-e, and the scraps are selected according to the guillotine shear with different cutting ability. However, by moving to the vicinity of each shear, the scrap can be efficiently disassembled and / or broken and / or separated, and the quality of the separated scrap is improved.

  Further, by arranging a plurality of self-propelled dismantling work vehicles 18a to 18e on the scrap processing work floor 3 and providing a plurality of work areas 19a to 19e for performing scrap dismantling, breaking and sorting operations, The worker is prohibited from entering the stage, and only the self-propelled dismantling work vehicles 18a to 18e can enter the stage. As a result, the occurrence of accidents to live workers due to scraps, machines, etc. can be extremely reduced.

  FIG. 3 is an explanatory view showing a plan configuration of another embodiment of the stage type scrap processing yard of the present invention. As shown in FIG. 3, the scrap processing work floor 33 is disclosed as having a substantially square planar shape. Moreover, the arrangement | positioning of the group of unloading position 34a, b and installation loader 35a, b and guillotine shear 42a, b was arrange | positioned point-symmetrically on the opposing side. On the scrap processing work floor 33, a hydraulic operation boom 45 having an opening / closing work tool 44 for sandwiching scraps and removing non-ferrous metals and plastics at the tip, and a pair of left and right arms 47 having a sandwiching tool 46 are provided on the vehicle. Six multi-type self-propelled dismantling work vehicles 48a to 48f provided at the front part or the rear part are arranged. Each of the self-propelled dismantling work vehicles 48a to 48f has work areas 49a to 49f determined for each worker.

  About the unloading positions 34a and 34b, the traveling path 32 where the unloading position exists is made into 2 lanes, and safety is ensured. Specifically, when transporting mainly scraps to be cut by the guillotine shear 42a having a large cutting output, it enters the yard 31 from the traveling path 32a toward the guillotine shear 42a and has a small cutting output. When transporting mainly scraps to be cut at 42b, the scrap enters the yard 31 on the travel path 32b toward the guillotine shear 42b. Immediately before the traveling roads 32a and 32b cross or separate from each other or immediately before entering the auxiliary traveling road 32b facing the unloading position, safety is ensured as a temporary stop.

  For the two guillotine shears 42a and 42b, the cutting ability of the guillotine shear 42b was made smaller than that of the guillotine shear 42a. In the present embodiment, two sets of unloading positions and installation loaders and guillotine shears are used, but two or more may be used depending on the size of the scrap processing work floor.
