As shown in FIG. 2, a swash plate 73 for guiding the separated material to a container 72 located in front of the leg member 70 is fixed below the discharge port 38 between the leg members 70. ing.

A substantially U-shaped chute table 67 as viewed from the rear is fixed to the rear of the apparatus frame 58 so as to extend from the fixed plate 57 to the rear.

The apparatus for separating unnecessary substances such as labels according to the present embodiment has the above-mentioned configuration. Hereinafter, a method of using the apparatus for separating unnecessary substances such as labels will be described. In the following description, the separating hydraulic pump 22 and the feeding hydraulic pump
45, the peripheral speed of the blade end 34 of the rotary blade 33 is 15 m /
The case where the peripheral speed of the feed blade 50 is set to 0.5 m / s in S will be described.

First, when the plastic container collected and transported by the collection vehicle or the like is placed on the chute table 67 and pushed into the feeding means 43, the plastic container on the chute table 67 moves onto the fixed plate 57. Then, it is fed to the rotating rotor 19 by the feeding means 43. At this time, the plastic container is pressed by the feed roller 49 and a perforation is formed.

Then, the rotating rotor 19 is fed by the feeding means 43.
While being pressed and deformed by the rotating rotor 19, the label is peeled off and the mouth is cut off. Specifically, the label is scraped off by a rotating blade 33 sliding on the surface of the plastic container, and an opening formed harder than other portions is inserted through a gap between the rotating blade 33 and the fixed blade 59. It is considered impossible to do so and will be cut off.

In this way, the plastic container, the label, the mouth, and the like separated and discharged from the discharge port 38 of the apparatus main body 17 are stored in the container 72.

The plastic containers and the like housed in the container 72 are sorted into those to be conveyed to the next step for reuse and those that are not needed. This sorting is performed by using any of mechanical sorting such as sieve sorting and wind sorting, or manual sorting, or a combination thereof.

Since the apparatus for separating unnecessary substances such as labels according to the present embodiment is used as described above, it has the following advantages.

Since the chute 67 is provided, a plastic container can be placed on the chute 67,
In particular, by feeding the plastic container into the loading section 68 comprising the chute table 67 and the fixing plate 57, the feeding means 43 can be accurately placed.
Can be fed to the rotating rotor 19.

Further, since the loading section 68 composed of the fixing plate 57 and the chute table 67 is provided to be inclined downward toward the rotating rotor 19, the plastic container that has been loaded is fixed.
The plastic container on the fixed plate 57 can be easily fed to the rotating rotor 19 by the feeding roller 49 by being easily slid along the 57 and the chute table 67 to the rotating rotor 19 side, so that the separating operation can be performed smoothly. In addition to this, there is no need to employ a conveyor such as a belt conveyor as the lower fixing plate 57, and the size and weight of the feeding means 43 can be reduced.

Further, since a feeding roller 49 which can move up and down, that is, is retractable with respect to the fixed plate 57 is employed as the feeding means 43, the feeding roller 49 is formed by a plastic container placed on the fixed plate 57. It can be moved up and down to feed according to the amount and size of the plastic container charged, and it can be fed while pressing the plastic container by its own weight of the feed roller 49. The container does not inadvertently escape from the rotary blade 33, and the label or the like can be separated accurately. In particular, by pressing the plastic container toward the fixing plate 57 by the weight of the feed roller 49 in this manner,
Since the plastic container is primarily compressed, the rotating blade is accurately
It is easy to get caught between 33 and the fixed blade 59.

Further, since the pivot shaft 55 of the swinging member 53 to which the feed roller 49 is attached is located on the front side of the rotary roller 19, the feed roller 49 can be moved up and down by the swing of the swing member 53. The feeding of the plastic container can be approximated in the vertical direction, and the feeding means 43 can be mounted compactly on the apparatus main body 17. In addition, since the pivot shaft 55 of the swing member 53 is provided forward and below the rotation shaft 51 of the feed roller 49, a force acts forward on the feed roller 49 by the plastic container on the fixing plate 57. However, the swinging member 53 swings by this force, and the feeding roller 49 can be raised.

The feeding blade 50 has a projection 50 with a sharp tip.
Since a is protruded, a hole for venting air can be formed in the plastic container when the plastic container is fed by the feed roller 49 by the projection 50a, and the plastic container is easily compressed. That is, since the feeding means 43 is provided so that a perforation can be formed in the plastic container at the time of feeding,
When the plastic container is compressed, the deformation of the plastic container can be prevented from being hindered by the air inside the plastic container, and the air inside the plastic container can be accurately discharged from the formed perforations to reduce the volume of the plastic container. It has the advantage that.

Further, since the feeding roller 49 has a sufficient weight to press and deform the plastic container placed on the fixing plate 57, the plastic container on the fixing plate 57 is primarily compressed by its own weight. Can be sent while
It is easy to bite between the rotary blade 33 and the fixed blade 59.

Further, a feed hydraulic pump 45 for rotating the feed roller 49 and a separating hydraulic pump 22 for rotating the rotary rotor 19 are separately provided, and a hydraulic circuit for the feed means 43 is provided. Since the hydraulic circuit for separation is provided separately, the feeding means 43 can be driven arbitrarily even when the separation device is stopped, whereby a plastic container is provided between the rotary blade 33 and the fixed blade 59. Feed roller 49
Can be reversely rotated.

The discharge amount of the feed hydraulic pump 45 and the separation hydraulic pump 22 is such that the peripheral speed of the blade end 34 of the rotary blade 33 is 15 m / s and the peripheral speed of the feed blade 50 is 0.5 m. / S,
That is, since the feeding roller 49 is controlled to feed the plastic container at a speed lower than the peripheral speed of the rotary blade 33, the speed of the plastic container passing through the gap between the rotary blade 33 and the fixed blade 59 can be adjusted to some extent, The accuracy of separation of the label and the mouth by the rotary blade 33 can be improved. Moreover, by changing the discharge amount of the feed hydraulic pump 45 or the separating hydraulic pump 22, the blade end portion 34 of the rotary blade 33 and the feed roller
The peripheral speed ratio with 49 can be changed and set according to the purpose of work.

Further, the rotating rotor 19 is provided with a separated label and a relief portion 28 capable of retracting the mouth from the projecting position of the blade end 34 of the rotary blade 33 in the rotating direction. Separated label, mouth is the escape of rotating rotor 19
It does not escape to 28 and does not hinder the rotation of the rotating rotor 19.

Further, a substantially L-shaped mounting notch 29 is formed on the rotary blade.
The rising surface against the mounting surface 30a that abuts the side surface of 33
Since the peripheral side of 30b is formed so as to be inclined toward the blade end 34, centrifugal force acts on the rotary blade 33 and the holding member 31 attached to the mounting notch 29 when the rotary rotor 19 is rotated at high speed. However, a reaction force from the rising surface 30b acts on the holding member 31 against this centrifugal force, and the holding member 31
The rotary blade 33 can be accurately held by the 31 and the force acting on the bolt 37 as a fixing means can be reduced.

The hole 35 for mounting the rotary blade 33 is a blade end.
It is formed as a long hole extending to the 34 side, and the rotary blade 33 is
Is provided slidably on the blade end 34 side, so that the bolt 37 is loosened to release the holding by the holding member 31, and the rotary blade 33 is slid along the hole 35 to rotate the rotary blade.
The protruding length of 33 blade end 34 can be adjusted, fixed blade
The distance between 59 and rotary blade 33 can be changed as appropriate. In particular, since the hole 35 is formed with a width substantially equal to the outer diameter of the leg of the bolt 37, the rotary blade 33 does not shift in the lateral direction (the axial direction of the rotary rotor 19) during this sliding.

In addition, since the rotary blade 33 is sandwiched and mounted by the pressing member 31, even if the rotary blade 33 is slid toward the blade end 34 along the hole 35, the pressing member 31 is attached. This has the advantage of receiving the reaction force of the centrifugal force from the rising surface 30b.

Further, the rotary rotor 19 can be easily manufactured by engraving the notch 29 for attachment and the escape portion 28 adjacent to each other, and the rotating blade 33 and the pressing member 33 are bolted to the notch 29 for attachment. There is an advantage that the rotary blade 33 can be easily mounted on the rotary rotor 19 by mounting the rotary blade 19.

Further, since the apparatus main body 17 can be mounted at a high place by the leg members 70, the capacity of the container 72 for storing the separated material can be increased.

Further, since the discharge port 38 is provided with a swash plate 73 for guiding the separated matter to the container 72 located in front of the leg member 70, there is an advantage that the container 72 can be easily replaced. Also have.

Further, since the contents accommodated in the container 72 as described above are separated into a plastic container, a label, a mouth and the like, subsequent sorting operations such as manual sorting and sieving are easy. It has the advantage that it can be performed reliably. However, when the label etc. is stuck with an adhesive etc., there are cases where it is not completely separated from the plastic container.In such a case, the plastic container must be separately sorted by the operator. Becomes
