7 and the pair of rotary crushing cutters 28 and 29 are connected to the input port 2
4 and the discharge port 25 are arranged above and below. These rotary crushing cutters 26 to 29 constitute a crushing section for scrap tire pieces. The pair of rotary crushing cutters 26, 27 located on the upper side include rotary shafts 26a, 27a rotatably supported by the main body case 23, and collars 26c, 27c (FIG. 10) Rotary crushing blades 26b, 27b mounted at equal intervals via
It has and. The positional relationship between the rotary crushing blade 26b of the one rotary crushing cutter 26 and the rotary crushing blade 27b of the other rotary crushing cutter 27 will be described. One of the rotary crushing blades has a blade width with respect to the other rotary crushing blade. They are arranged offset from each other in the axial direction of the rotary shafts 26a and 27a. The blade portion 26b1 of the rotary crushing blade 26b and the rotary crushing blade 27
The blade portion 27b1 of b can mesh with each other as the rotary crushing cutters 26, 27 rotate (FIG. 3). 12
As shown in FIG. 7, a gap 30 between the blade portion 26b1 of the rotary crushing blade 26b and the blade portion 27b1 of the rotary crushing blade 27b in the meshed state, which is sufficient to allow the waste tire piece to enter, is provided.
(Fig. 20). The width of the gap 30 is appropriately set according to the size of the scrap tire piece. The upper pair of rotary crushing cutters 26, 27 are rotatable in a direction in which they mesh with each other (opposite direction) as the motor 31 is driven. That is, the shaft 31a of the motor 31 is connected to the rotary shaft 26a of the one rotary crushing cutter 26 on the same straight line (FIGS. 1 and 3). Therefore, the rotational force of the motor 31 is directly transmitted to the one rotary crushing cutter 26 through the rotary shaft 26a. The rotating wheel 32 is attached to the shaft 31 a of the motor 31. The rotary wheel 32 meshes with a transmission wheel 33 attached to the rotary shaft 27a of the other rotary crushing cutter 27 as shown in FIG. Therefore, the rotational force of the motor 31 is transmitted to the other rotary crushing cutter 27 through the rotary wheel 32, the transmission wheel 33 and the rotary shaft 27a. By the way, in the example of FIGS. 12 to 14, the blade portion 26b1 of the rotary crushing blade 26b and the blade portion 27 of the rotary crushing blade 27b.
An exchange blade 34 is detachably attached to b1.
The replacement blade body 34 forms the main body of the blade portions 26b1 and 27b1. The configuration and mounting state of the replacement blade 34 will be described with reference to FIGS. 13 to 19. The exchange blade 34 shown in FIGS. 18 and 19 has one or more grooves 34a (three in FIG. 18) formed on both side surfaces. One end of each groove 34a, that is, the end of the rotary crushing blade 26b on the rotation direction side (direction of the arrow in FIG. 13) is opened, and the other end is closed. In this way, each groove 34a has a bag shape. When the blade portion 26b1 of the rotary crushing blade 26b is in mesh with the blade portion 27b1 of the rotary crushing blade 27b, one end of each groove 34a is opened downward (see FIG. 13). As shown in FIG. 19, the exchange blade 34 has a bolt through hole 34b formed in the center thereof, and a mounting groove 34c formed in the vertical direction at the back thereof. The mounting groove 34c of the exchange blade 34 can be fitted to the rib 26b2 (FIG. 15) formed on the blade portion 26b1. As shown in FIGS. 14 to 17, the replacement blade body 34 includes the blade portion 2
6b1 is installed, the mounting groove 34c and the rib 26
and b2 are fitted together. In such a fitted state, the replacement blade body 34 is fixed to the blade portion 26b1 by the fixing bolt 35 inserted into the bolt through hole 34b. The exchange blade 34 can be removed from the blade portion 26b1 by releasing the fastening of the fixing bolt 35. Such replacement blades 34 are attached by fixing bolts 35 to blade portions 26b1 formed at a plurality of locations (six locations in FIG. 14) at equal intervals on the outer periphery of the rotary crushing blade 26b. The replacement blade body 34 is replaced with another one in the event of a situation of replacement such as damage of the blade. As shown in FIG.
An exchange blade 34 is attached to each blade portion 27b1 of the rotary crushing blade 27b of the rotary crushing cutter 27 in the same manner as the blade portion 26b1 of the rotary crushing blade 26b. Figure 1
2, as shown in FIGS. 13 and 20, the rotary crushing blade 26b
And the rotary crushing blade 27b mesh with each other (see FIG. 12).
When it is in a state of being adjacent to each other on the left and right, when the scraps of scrap tires and the shredded pieces of scrap tires are forcibly shredded, and at the same time, the wires are embedded in the scraps of scrap tires and scraps of scrap tires. Acts to separate the wire from the rubber portion.
This separating action depends on the gap 30 between the blade portion 26b1 of the rotary crushing blade 26b and the blade portion 27b1 of the rotary crushing blade 27b. To describe the action of the gap 30, the scraps of the waste tire and the crushed pieces of the waste tire are the blade portion 26b1 and the blade portion 2
Rather than being cut linearly in the vertical direction by 7b1, a part of the cut body, the crushed piece itself or a part thereof enters the gap 30 and is sandwiched by the blade portions 26b1 and 27b1 and is in opposite directions. It is crushed while being pulled by. In the process in which the cut body and the crushed pieces are crushed while being pulled, the contact state between the wire and the rubber portion is released and the wire is separated from the rubber portion. Further, at the time of crushing, as shown in FIG. 20, the grooves 34a of the exchange blades 34 that are adjacent to each other on the left and right are adjacent to each other, and a part of the cut body or a rubber part of the crushed piece is eroded into each groove Left and right blades 26b1,
27b1 moves in the opposite direction. The cut body and the crushed pieces are crushed while being held by the exchange blade 34 while being pulled in opposite directions, so that the close contact state between the wire and the rubber portion is further released, and the wire is separated from the rubber portion. Will be. An explanation of the principle for simultaneously performing such crushing and separation will be given later. The configuration and operation of the lower pair of rotary crushing cutters 28, 29 are substantially the same as those of the upper pair of rotary crushing cutters 26, 27. Therefore, detailed description of the configuration and operation of the rotary crushing cutters 28 and 29 is omitted. In FIG. 13, 28b
Reference numerals 1 and 29b1 are blade portions formed on the rotary crushing blades 28b and 29b, and the exchange blade body 34 is attached to these blade portions. As shown in FIGS. 1, 3 and 11.
The rotational force of the motor 36 is transmitted to one rotary crushing cutter 29 via a rotary wheel 37 attached to the shaft 36a and a transmission wheel 38 attached to the rotary shaft 29a. The rotational force of the motor 36 is transmitted to the other rotary crushing cutter 28 through the rotary wheel 37, the transmission wheel 38, and the transmission wheel 39 attached to the rotary shaft 28a. Therefore, when the scrap of the waste tire cut into a predetermined size by the cutting means is loaded into the main body case 23 from the loading port 24 of the crushing device 4 shown in FIG. Crushed by the rotary crushing cutters 26 and 27, and at the same time the wire is separated from the rubber part, and then crushed by the lower rotary crushing cutters 28 and 29, and at the same time the wire is separated from the rubber part, resulting in chip-like crushing. It becomes a piece and falls into the drum main body 5 of the sorting rotary drum 1 from the discharge port 25 together with the separated wire. In the drum body 5, only the crushed pieces of the waste tire of a specific size pass through the sorting hole 6 and are discharged onto the conveyor 21 of the collecting means 3. The discharged crushed pieces are carried to the stacking section 22 (FIG. 21) by the conveyor 21. The wire passing through the sorting hole 6 is also carried to the stacking unit 22 by the conveyor 21.

The processing operation of the waste tire will be described. As shown in FIG. 21, a method for selecting and treating an object to be treated such as a crushed piece of a waste tire using a sorting device A incorporated in a waste tire processing line will be described. [1] Pretreatment In the example of FIG. 21, first, the bead wire of the waste tire T is extracted by the bead wire extracting device 40. A thin belt wire is left inside the waste tire T from which the bead wire has been removed. Then, the waste tire T from which the bead wire has been removed is conveyed to the tire cutting device 42 by the conveyor 41. In the tire cutting device 42, the waste tire T is cut into a plurality of pieces with a predetermined width in the radial direction, for example. After that, the cut piece T1 of the waste tire cut into several pieces is conveyed to the heating device 43. The heating device 43 heats these cut bodies by using heating means such as high frequency or electromagnetic induction. When the cut body T1 is heated, the belt wire embedded therein is released from the close contact with the rubber portion.
Further, the heated cutting body T1 is conveyed to the sorting apparatus A by the conveyor 44 and is thrown into the main body case through the feeding port 24 of the crushing apparatus 4. [2] The cut body T1 that has been crushed and input is, as shown in FIGS. 1 and 3,
The upper rotary crushing cutters 26 and 27 crush the wire, and at the same time the wire is separated from the rubber part, and the crushed pieces are subsequently crushed by the lower rotary crushing cutters 28 and 29, and at the same time the wire is separated from the rubber part. The crushed pieces and the separated wire fall from the discharge port 25 into the drum main body 5 of the sorting rotary drum 1. [3] Sorting and crushing again The crushed pieces of waste tire and the wires that have fallen into the crushing drum body 5 are sorted by the sorting hole 6 of the drum body into those of a specific size and those of other sizes. Only the crushed pieces and the wire of the waste tire of a specific size pass through the selection hole 6 in the drum body 5 and are discharged onto the conveyor 21. The discharged fragments and wires are collected by the conveyor 21 in the stacking unit 2
Carried up to 2. The drum body 5 cannot pass through the sorting hole 6
The crushed pieces and wires left inside are carried by the partition plate 8 to the position directly above the main body case 23 as the drum main body rotates in the direction of the arrow in FIG. Then, it falls under its own weight into the charging port 24 and is crushed again by the crushing device 4. At the time of crushing, the wire contained in the crushed pieces is separated from the rubber portion of the tire. Thereafter, the crushed pieces and the wires dropped from the discharge port 25 of the crushing device 4 into the drum body 5 are sorted by the drum body. Of the crushed pieces and the wires, those that have passed through the selection hole 6 are carried to the stacking section 22 by the conveyor 21. [4] Recovery The crushed pieces and the wires carried to the accumulating section 22 as shown in FIG. 21 are crushed with the magnetic crusher 45 continuous to the end of the conveyor 21 and have the crushed pieces and the wire made of rubber. It is classified into three types, a piece and a wire. The magnetic sorter 45 is a drum type in the illustrated example,
An electromagnet is fixedly built in the rotating drum. Therefore, among the crushed pieces, those made of only rubber fall to the first stacking portion 22a without being attached to the drum surface. The crushed pieces having the wire and the wire are attached to the surface of the drum. The crushed piece having the wire attached to the drum and the wire are gradually weakened when the drum is gradually separated from the magnetic range by rotating the drum by a predetermined angle. As a result, the crushed pieces having the wire are first separated from the drum and dropped into the receiving port 22b, and then the wire is dropped into the second collecting portion 22c and collected. The crushed pieces with a wire, which are collected in the receiving port 22b, are loaded into the loading port 24 of the crushing device 4 by a conveyor (not shown) and processed. In this way, the crushing and the sorting are repeated, and only the crushed pieces having a predetermined size and the wire removed and the wire are collected.

Here, the crushing and the separation performed simultaneously by the crushing device 4 means the following separation crushing principle (1-1),
It is considered to be based on (1-2) and (1-3). These principles are explained by taking the rotary crushing blades 26b and 27b as an example. First, the separation and crushing principle (1-1) will be described with reference to FIG. The scrap T1 of the waste tire is crushed by the rotary crushing blades 26b and 27b. In this crushing process, as shown in FIG. 22A, a part of the cut body T1, a crushed piece, or a part of the crushed piece (hereinafter collectively referred to as “processed piece”) enters the gap 30, and the processed piece T.
A part of 10 is also bitten in the groove 34a in a compressed state (engaged in the groove). In this state, the rotary crushing blade 2
Since 6b and 27b rotate in opposite directions about the rotation axis, the blade portion 26b1 and the blade portion 27b1 gradually approach each other, eventually come into mesh with each other, and then gradually move away from each other. While the blade portions 26b1 and 27b1 were separated from each other, the processing piece T10 sandwiched in the groove 34a was forcibly separated into two crushed pieces T11 and T12, and at the same time, was not separated due to the existence of the gap 30. The wire W is pulled out from one crushed piece T12 (FIG. B). This kind of separation and extraction is carried out continuously. At the time of crushing, separation and extraction are performed by the gap 30, and the bag-shaped groove 3 is formed on the separation and extraction.
It is considered that the separation and the withdrawal are more effectively performed by 4a. In addition, during such crushing work,
Most of the crushed pieces with the wire W still attached are returned to the crusher 4 again by the rotary drum 1 for sorting. Next, the separation and crushing principle (1-2) will be described with reference to FIG. The crushed piece T13 with the wire W attached to the crushing device 4 again is inserted into the gap 30 between the rotary crushing blades 26b and 27b as shown in FIG.
It is possible to pull out the wire W by being sandwiched by a and the other crushed piece T14 is drawn into the other groove, and the action of crushing the wire W by both crushed pieces (FIG. B). ,
Conceivable. Furthermore, the separation and crushing principle (1-3) is shown in FIG.
Will be described with reference to. As shown in FIG.
0 enters the gap 30 between the rotary crushing blades 26b and 27b,
Both side portions of the processed piece are also bitten in the groove 34a in a compressed state. In this state, the rotary crushing blades 26b, 27
Since b rotates about the rotation axis in opposite directions,
The blade portions 26b1 and 27b1 gradually come close to each other, mesh with each other, and then gradually move away from each other. Blades 26b1, 27b1
In the process of moving away from each other, both sides of the processing piece T10 sandwiched in the groove 34a are pulled in opposite directions to each other.
At the same time as the crushed pieces T15 and T16 are forcibly separated, the wire W is separated from these crushed pieces (FIG. B). The crushing principle (2) will be described with reference to FIG. This principle is based on the separation and crushing principle (1-1), (1-2), (1
-3) is to facilitate understanding. The crushing principle (2) is a principle of cutting a wire without separating it. As shown in FIG. 25, the rotary crushing blades 126b, 127
b has a small gap, and the processed piece T10 is cut into crushed pieces T17 and T18 at the time of crushing and divided into two, and the wire W is also cut at the same time. Separation and crushing principle (1-1), (1
-2) and (1-3), the processed piece T10 is provided between the rotary crushing blades (the rotary crushing blades 26b and 27b in the figure).
By providing a gap 30 into which the blade can be inserted and by the presence of the groove 34a in the blade portion in the meshed state, the processing piece T10 is crushed (divided by forced pulling) and the wire is separated from the rubber portion ( It is presumed that the withdrawal) is performed at the same time.

According to the example shown in FIG. 1, the rotary drum 1 for selection is provided with a crushing device 4 therein, and crushed pieces and wires discharged from a discharge port 25 of this crushing device are used for the drum body 5.
It is possible to drop directly inside. For this reason, a transportation means for the crushed pieces and the wire is not required, and the crushing and the sorting are continuously performed smoothly. When the crushed pieces and the wire left in the drum body 5 are crushed again, the drum body can be directly supplied to the charging port 24 by rotating while holding the drum body inside thereof. Therefore, there is no need for a means for carrying the crushed pieces or wires for crushing again to the charging port, and the supply and the recrushing are continuously performed smoothly. Regarding the rotation driving means 2, in the above example, the selection rotary drum 1 is rotated by using the guide portion 7 and the feed wheel 18, but the present invention is not necessarily limited to this example, and for example, a rotary belt is provided on the outer periphery of the selection rotary drum. A configuration may be used in which one end is wound around and the other end side is connected to the motor. In the crushing device 4 shown in FIG.
Although the rotary crushing cutters 26 to 29 are arranged in upper and lower two stages, only one stage or three or more stages may be arranged. The interval between the rotary crushing blades of the meshing rotary crushing cutter may be extremely narrow as shown in FIG. Further, the rotary crushing blades 26b to 29b shown in the above example are provided with exchange blade bodies 34, but the main body of the blade portion does not necessarily have to be exchangeable. The structure of the blade is not limited to that shown in the figure. Further, the rotary crushing cutters 226 to 229 shown in FIG.

The blade portion 226b1 in b and the blade portion 226Ab1 in the other rotary crushing blade 226Ab indicated by the chain line may be arranged so as to be offset by a predetermined angle. Other rotary crushing blades 227b, 2
27Ab, rotary crushing blades 228b and 228Ab, and blade portions 227b1 and 227b of rotary crushing blades 229b and 229Ab.
28b1 and 229b1 and blades 227Ab1 and 228Ab
The relationship with 1,229Ab1 has a similar arrangement relationship. Grooves 234 are formed directly on both side surfaces of the blade portions 226b1, 227b1, 228b1, 229b1 so that these grooves 23
4 has the same function as the groove 34a of the exchange blade 34. Blade 226Ab1, 227Ab1, 228Ab
The 1 and 229 Ab 1 are also formed with grooves (not shown) similar to the grooves 234 of the blade portions 226 b 1 to 229 b 1.
The crushing unit of the crushing device 4 is not limited to the illustrated rotary crushing cutter. The object to be processed by the processing device is, in addition to the waste tires as described above, scrap metal generated from scrap vehicles, waste such as non-metal for scrap, processed raw materials,
Processed goods are included.

[0013]

According to the present invention, the object to be treated such as waste can be processed through the rotation of the rotary drum for selection, and a shaker that horizontally moves and a long rotary cylinder unlike the prior art are not used. Therefore, the efficiency of the installation space can be improved. According to the present invention, since the crushing device is provided in the sorting rotary drum, the conveying means is unnecessary, so that the crushing work and the sorting work can be continuously performed without expanding the installation space, and the work efficiency can be improved.
