Waste bin B is conveyed in the direction indicated by arrow A ₁ to A _5.

[0004]

However, after the waste bottles B are arranged in a line in the longitudinal direction of the waste bottles B by the bottle aligning device 3, the waste bottles B are perpendicular to the longitudinal direction of the waste bottles B. Transfer to the bucket conveyor 4 that transports the. The transfer direction of the waste bottle B may fail because the direction of movement is suddenly changed at the time of connection. For example, there is a possibility that the sheet is conveyed across the adjacent bucket 4a without entering the predetermined bucket 4a. Further, there is a case where the waste bottle B that has entered the bucket 4a is transported while standing. If it is conveyed in such a state, the waste bottle B
Color identification may be impossible, or the device itself may be damaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a waste bottle sorting apparatus according to the present invention will be described below with reference to FIGS. FIG. 1 is a schematic view of a waste bottle sorting apparatus for sorting waste bottles by color. In FIG. 1, a color collecting device includes a waste bottle supplying device 1, a roller type size separating device 2 provided with a sorting device in which a width between rollers is gradually increased, a bottle aligning device 3, a bucket conveyor. 10, a shooter 5, a bottle color detector 6, and a control device 7.

In the waste bottle sorting apparatus, a waste bottle B is fed from a waste bottle supply device _{1 in the} direction of arrow A1 and supplied to a roller type size sorter 2. Waste bin B fed into the roller size sorter 2 is discarded bottles B are conveyed in the arrow A ₂ direction, waste bin B by falling from the width between the rollers in accordance with its size are separated. The classified waste bin B is fed fractionated to a size of waste bin B is conveyed in the arrow A ₃ direction to the bottle aligner 3 is supplied to the bucket conveyor 10 by one by one alignment. In addition, waste bottle B
Is not limited to a roller-type size separator, and various known devices can be used.

The bucket conveyor 10 includes a bucket 10a
A bottom plate 10b that can be opened and closed is provided at the bottom of the bottom plate. The bucket conveyor 10 is provided with bottle color discriminating means (a bottle color detector) 6 for identifying the color of the waste bottle B by transmitted light. The signal from the bottle color classification means 6 is input to the control device 7. The control device 7 opens the bottom plate 10b of the bucket conveyor 10 on which the waste bottle B of that color is placed according to the color detected by the bottle color classification means 6 and drops it onto the shooter 5, thereby disposing of the waste bottle. Bottle B is sorted by color. Thus, the waste bottle B is transported and separated in the directions indicated by arrows A _{1 to} A ₆ .

A transfer box 13 is provided on the bucket conveyor 10.
Is provided. The transfer box 13 includes a glide swash plate 11, a posture control plate 12, a stopper 14, and standing bottle falling plates 15, 16 as restriction plates for restricting the waste bottle B to be placed at a predetermined position of the bucket 10a. Is provided.

Next, the connecting box 13 will be described in detail with reference to FIGS. Figure 2 shows the bucket conveyor 1
0 is a side view of the transfer box 13, and the waste bottle B is transferred from the bottle alignment device 3 via the transfer box 13 to the bucket conveyor 1.
The figure mounted on the bucket 10a of No. 0 is shown. FIG. 3 is a plan view, and FIG. 4 is a cross-sectional view taken along line XX 'of FIG.

Referring to FIG. 3 and FIG. 4, the waste bottle B is put into the bucket conveyor 10 via the bottle alignment device 3. A glide swash plate 11 is provided at the input portion of the waste bottle B, and the glide swash plate 11 is inclined downward in the transport direction with respect to a vertical plane, and the angle is defined as an inclination angle θ. When the waste bottle B is inserted from the inlet, the inclination angle θ
Is supplied along the gliding swash plate 11. At the same time, the bucket conveyor 10 is moving at a speed of, for example, 45 m / min, and the charging speed of the waste bottle B is about 80 m / min. When the waste bottle B falls along the gliding swash plate 11, the bucket 10a
It is thrown into. When the waste bottle B falls along the gliding swash plate 11, the body of the waste bottle B also comes into contact with the attitude control plate 12 hanging down from above the bucket conveyor 10, and the waste bottle B
Is placed in a predetermined position on the bucket 10a. The attitude control plate 12 may be fixed, but by giving a certain degree of elasticity, it is possible to reduce the impact when the waste bottle B is charged. Of course, when the attitude control plate 12 is fixed, the gliding swash plate 11 and the attitude control plate 12
Is set so that the waste bottle B can sufficiently pass through. The inclination angle θ of the gliding swash plate 11 is, for example, 60 to 45.
Degrees, preferably 45 degrees. The materials of the gliding swash plate 11 and the attitude control plate 12 may be formed of a flexible thin plate such as plastic or a composite material of a flexible thin plate such as plastic and a hard material such as an iron plate.

Also, depending on the size of the waste bottle B, when it is put into the bucket 10a, the feeding speed is not reduced in the small bottle.
Collision 4 Bounced back by the bottle stopper 14,
The waste bottle B comes into contact with the attitude control plate 12 and the bucket 10a.
And stored in a predetermined position of the bucket 10a. In particular, since the deceleration of the small bottle by the gliding inclined plate 11 is insufficient, the bottle stopper 1
4 is decelerated by colliding with
a. As the bottle stopper 14, a rubber plate capable of absorbing an impact, a resin plate having elasticity, or a plate made of a composite of a plate made of these materials and a hard iron plate is used.

However, since the waste bottle B moves more than expected, the standing bottle falling plate 15,
By providing the waste bottle 16, the upper portion of the waste bottle B raised in the bucket 10 a comes into contact with the bottle falling plate 15 or 16, and receives a diagonal force on the waste bottle B so that the waste bottle B falls into the bucket 10 a. Is stored. Needless to say, a plurality of waste bottles B are placed on the same bucket
Is never stored. Standing bottle defeat boards 15, 16
The inclination angle β is set to about 45 degrees on the side surface of the transfer box 13 with respect to the transport direction of the bucket.

As described above, the gliding swash plate 11, the attitude control plate 12, the connecting box 13, the bottle stopper 14, and the standing bottle dropping plates 15, 16 place the waste bottle B at a predetermined position on the bucket 10a. And a regulating plate for regulating the movement of the waste bottle. The movement of the waste bottle is regulated by providing an input port for the waste bottle and a regulating plate behind it, so that the waste bottle is stored in a predetermined position of the bucket. The shape and the like of the regulating plate are not limited to the above embodiments, and various embodiments can be assumed.

[0019]

As described above, according to the present invention,
At the transfer from the bottle aligner to the bucket conveyor, the direction of movement of the waste bottle changes by 90 degrees, and the speed of the bucket conveyor is as fast as 45 m / min. There is a case where the waste bottle is stored in a predetermined position of the bucket by providing an inclined plate or the like for regulating the movement of the waste bottle. There is an advantage that identification failure does not occur. In addition, since it is not placed across the buckets, it is possible to prevent the waste bottle sorting device from being damaged.

Further, according to the present invention, since the bottle stopper is provided, even if the waste bottle is thrown in without deceleration, the waste bottle can collide with the bottle stopper and be stopped. Has the advantage that it can be stored in a bucket.

According to the present invention, there is a case where the waste bottle stands on the bucket though the probability is low, and even in such a case, the waste bottle is placed on the bucket by the provision of the standing bottle falling plate. Since it can be tilted to the position, the possibility of occurrence of color identification failure is reduced.
