Next, referring to FIGS. 4 and 5, the moving mechanism 16
And 17 will be described, but since they have the same configuration, only one moving mechanism 17 will be described.

In FIG. 4, slide plates 23A and 23B are provided on the side wall of the hopper portion 14 so as to cover the openings 14a and 14b having the shape shown in FIG. The side wall is slidably provided, for example, at a slight gap from the strip plate 24 fixed by welding, and the strip plate 24 is formed with a round hole 24a. A bolt 25 is planted on the side wall of the hopper 14 by inserting it, and a detachable strip plate 27 abuts against this, which allows the bolt 25 to be inserted into a plurality of bolt insertion holes 27a. The upper end of the slide plate 23A is fixed to the hopper portion 12 by tightening the lock nut 26 thereto.
A rail guide member 36 having an L-shaped cross section is attached to the lower end portion thereof, and a plurality of bolt insertion holes 36a are formed in the rail guide member 36. Bolts 38 are inserted into the rail guide members 36a and screwed in advance. By tightening the lock nut 37, the lower ends of the slide plates 23A and 23B can be fixed to the hopper portion 14.

A roller 22 which is a hollow cylindrical body is provided in the hopper portion 14, and both ends thereof are opened through lid members 32 and 33 having T-shaped cross sections attached to the both ends thereof.
It is provided in 4a and 14b and is movable left and right. The portions of the lid members 32 and 33 that project outward from the side wall of the hopper portion 14 are rotatably supported by bearings 30 and 31, and the outer race side is attached to the slide plates 23A and 23B. The bearing 30 is covered with a casing 42, and the other bearing 31 is covered with a cap 41. As a result, dust is removed from both ends of the branch roller 22 and the slide plate 2.
I try not to enter between 3A and 23B.

Further, the motor 4 is provided through a transmission mechanism (not shown).
The rotational force of 0 is transmitted to the inner races of the bearings 30 and 31. Therefore, the branch roller 22 is rotatably supported around its axis, that is, around the shaft portion protruding outward of the lid members 32 and 33.

The bolt 2 is provided directly below the branch roller 22.

It is in contact with one surface of the upper wall portion of the partition portions 18 and 19 to be formed.

The branch roller moving mechanisms 16 and 17 in the conventional non-magnetic metal separating belt conveyor device are constructed as described above. Next, their operation will be described.

3, municipal waste is discharged onto a belt conveyor 22 from a storage hopper (not shown), and these are conveyed in the direction of an arrow h. Among them, aluminum scrap m is above the cylindrical body 3 as is known. Then, due to the temporal change of the magnetic flux orthogonal to the aluminum scrap m due to the high speed and the same direction of rotation of the rotor 6 having the permanent magnets arranged concentrically with it, the mutual interaction with the magnetic flux. It receives a repulsive force due to the action, is blown along the trajectory of a, and is sorted and collected in the hopper portion 12. Ordinary dust g, for example, paper dust or plastic dust, receives the horizontal initial velocity of the discharge end of the belt conveyor 2 without being subjected to the repulsive force as described above, and thereafter falls naturally to cause the hopper portion 1 to drop.
Sorted and collected within 3. Further, the iron waste f is attracted by the magnetic force of the permanent magnet from the rotating body 6 and stays on the belt 2 for the longest time, but the guide roller 4 forcibly disengages this belt portion from the cylindrical body 3 so that the locus c is generated. It falls in the direction shown and is sorted and collected by the hopper unit 14.

As described above, aluminum scrap m, normal waste scrap g and iron scrap f are provided in the hopper parts 12, 13 and 14.
Is separated and collected, but if there is a branch roller 1
Dust that does not stick to the upper ends of the partition walls 18 and 19 and does not separate without 6, 7 is deposited on, for example, damp paper scraps or plastic scraps, and the separating and collecting operation as described above is performed. Since branch rollers 22 and 22 are provided on this because there is a possibility that it will interfere with the above, by the constant rotation in the directions shown by these arrows, even if the above-mentioned dust falls on it, it is constantly rotating, It is possible to forcibly drop dust into the storage space to the right of this. Since the space between the branch roller 22 and the upper walls of the partition walls 18 and 19 is defined by the guide plates 20 and 21, the space below the space is to be discharged into the intended waste storage space. You can

The conventional non-magnetic metal separation belt conveyor is constructed and operates as described above. However, the hopper parts 12, 13 and In some cases, the target collected waste may not be thrown into each of the fourteen. In this case, the branch rollers 22 and 22 are manually adjusted to the left or the right in the figure. Next, this operation will be described.

In FIG. 5, all the lock nuts 26 on the upper edge are loosened. Also, all the lower bolts 38 are loosened. After that, the slide plates 23a and 23b are moved in a desired direction. When this position is secured, all the lock nuts 26 are tightened again, and the lock nuts 37 screwed onto the bolts 38 below are also tightened, so that the slide plate 23
A and 23B are fixed to the side wall portion of the hopper portion 14.

As described above, the branch rollers 22, 22
The position of the lock nut 2 can be adjusted as described above.
6 must be loosened, and the bolt 38 below this
All the lock nuts 37 screwed to these must be loosened, and the adjusting action takes time and is troublesome.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A non-magnetic metal separating belt conveyor according to an embodiment of the present invention will be described below with reference to the drawings.

In the figure, the same components as those of the conventional example are designated by the same reference numerals and detailed description thereof will be omitted.

The hopper section 51 is also one of the hopper sections configured in the same manner as the conventional example (note that the following configuration is provided in a pair of left and right, but only one will be described below), but it has a rectangular shape. Is formed with an opening 51a of the mounting plate or slide plate 50 according to the present invention.
Is provided slidably in the direction of arrow p as clearly shown in FIG. An inverted L-shaped guide rail member 52 is fixed to the upper wall portion of the hopper side wall portion 51a by welding, for example, as shown in FIG.
Are formed on the guide rollers 54a and 54b.
Is rotatable in the direction of arrow p, and is fixed to the upper end of the slide plate 50 by a pair of attachment members 53a and 53b having a substantially L-shaped cross section. Such slide plates 50 are provided on both sides of the hopper portion 51. A bearing 57 is attached to the slide plate 50 in a substantially central portion as in the conventional case, and the bearing housing 55 is attached to the slide plate 50. And the cap 56 is the lid of this bearing 57.

A gear 50a is formed along the lower edge of the slide plate 50, and the gear 50a is formed by a pair of pinions 7.
It meshes with the gears 71a and 72a of the 1 and 72 gears,
These pinions 71 and 72 are fixed to their axial centers by rotary shafts 68 and 69, and one end of these pinions 71 and 72 is the support column 5.
It is rotatably fixed to bearings 64, 65 supported by 9, 60. The belt 63 is wound around the pulley between the bearing 64 and the pinion 69 of the one rotating shaft 66, and the rotational force of the electric motor 61 is transmitted thereby.

Further, in FIG. 2, a guide plate 8 is provided immediately below the branch roller 22 so as to be swingable around the axis of the bolt 80.
1 is provided. This may have the same structure as the guide plate 21 of the conventional example.

The aluminum non-magnetic metal separating belt conveyor according to the embodiment of the present invention has been described above. Next, this operation will be described.

Although not shown in FIGS. 1 and 2, the main body of the non-magnetic metal separating belt conveyor is the same as the conventional one. Therefore, although only a part of the waste container is shown in FIG. 1, for example, aluminum scraps m are selectively introduced into the hopper portion 51 which is one of the separated waste housing spaces. When it is desired to adjust the position of the branch roller 22, it is only necessary to drive the electric motor 61. This is performed by remote control in the present embodiment. For example, when it is observed that the aluminum scraps m are not properly put into the hopper section 51 by the image pickup of the video camera arranged in the vicinity of the sorting device, this video is displayed. The electric motor 61 is operated remotely while looking at the image of the camera. This rotational force drives the pinions 71 and 72 via the belt 63, whereby the slide plate 50 meshed with the pinions 71 and 72 is moved in one of the directions of arrow p depending on the rotation direction of the electric motor 61. Then, when the desired position is obtained, the driving of the electric motor 61 is stopped. At this time, if the motor brake is applied, it is possible to prevent the slide plate 50 from unexpectedly moving.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiment, the gear mechanism, that is, the gear 50a formed at the lower edge of the slide plate 50 and the gears 71a and 72a of the pinions 71 and 72 are engaged with each other so as to be moved to the left and right. Instead of this, a drive rod of an air cylinder or an oil cylinder is fixed to one of the left and right side edge portions of the slide plate 50, and hydraulic pressure of oil or pneumatic pressure of compressed air is supplied to this cylinder via a solenoid valve. , May be operated by this.
In this case, depending on the protruding length of the rod portion, the slide plate 50
It is clear that the position of is adjusted.

Further, in the above embodiment, the slide plate 50 is suspended by the mounting members 54a and 54b to which the rollers 54a and 54b are attached at the upper edge thereof, but the plate thickness of the slide plate 50 is further increased. And make it a stationary type. That is, a member having the same shape as the above-mentioned guide rail member is positioned below this lower edge portion, and the upper portion is restricted by some kind of restriction member so as not to swing gently, and the air cylinder is the same as in the above-described modified example. Alternatively, it may be moved by the drive rod of the oil cylinder.
