Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting apparatus for sorting bottles and the like collected for reuse according to their size.

[0002]

2. Description of the Related Art Conventionally, an apparatus that automatically sorts collected bottles according to type, color, and size in order to reuse the collected bottles requires a large space due to a planar structure. further,
The sorting device and the device that conveys the collected bottles and the like sorted by the sorting device have independent configurations. Therefore, in a limited installation space of a recycling center for recycling collected bottles, there is a problem in terms of space efficiency.

[0003]

Therefore, according to the present invention, a sorting device for collected bottles and the like is provided with a function of transporting the sorted collected bottles, and the conveyor for combined use of the transport and sorting is installed in multiple stages in the vertical direction. The purpose is to increase the efficiency of the installation space.

[0004]

A feature of the present invention is that a pair of conveyors having a predetermined interval in the horizontal direction are provided, and a pair of conveyors having a predetermined interval is provided. Directly below is where the transport conveyor is located along this gap. In the present invention, the size of the collection bottles and the like is sorted by the width of the gap between the pair of conveyors which also serves as the conveyance sorter. Collection bottles smaller than this gap fall from this gap and are dedicated to the conveyance located below. Is transported to a predetermined position by the transport conveyor. Further, the gap between the pair of conveyors which can also be used for sorting can be adjusted to be wide or narrow.

[0005] A feature of the invention according to claim 2 is that a pair of conveyors having a predetermined interval in the horizontal direction are provided in a plurality of stages in the vertical direction, and a plurality of conveyors are also provided between the plurality of conveyors. The interval is set to be narrower so as to be located at the lower stage, and the lowermost conveyor is disposed along the gap immediately below the interval between the pair of conveyors also serving as the transport / selection located immediately above the conveyor. There is a place. According to the present invention, the collection bottles and the like can be sorted into three or more types according to the size.

A feature of the invention according to claim 3 is that the pair of conveyors which are also used for carrying and sorting are installed in an inclined manner such that the insides thereof are mutually low. This angle of inclination is sufficient for the recovery bottle or the like to move smoothly toward the gap between the pair of conveyors which are also used for carrying and sorting.

[0007] The feature of the invention described in claim 4 is that of claim 2
In the invention described in the above, in a vertical gap between a pair of transport / selection conveyors installed in a plurality of stages, a buffer plate is provided so as to protrude into the space between the transport / selection conveyors. There is a place. This buffer plate is intended to prevent breakage although it is easily broken during sorting.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment in which a collection bottle is automatically sorted into four according to its size, and is conveyed. In the present invention, a pair of conveyors 1, 11, 2, 21, 3, which have both functions of conveyance and separation are provided. 31 are installed in three stages in the up-down direction, and each of the conveyors for conveying and sorting has intervals G1, G2, and G3 in the horizontal direction. The width is set narrower as it is located at the bottom. The pair of conveyors 1,11,2,21,3,31, which are also used for conveying and sorting, are installed in a slanted shape having a low inner side, that is, in an inverted C-shape. Is sufficient to smoothly move on the gaps G1, G2, and G3 between the conveyors which are also used for carrying and sorting. Further, the transport conveyor 4 dedicated to unloading disposed at the lowermost stage is disposed along the gap just below the interval G3 between the pair of conveyors 3 and 31 located at the third stage immediately above it. It is.

Therefore, the operation of sorting and transporting the collected bottles in this embodiment will be described. As shown in FIGS. 1 and 2, when the collected bottles are supplied to the conveyors 1, 11 at the uppermost stage, which are also used for transport and sorting. Since the bottle L of the size is larger than the gap G1, it is carried out by the conveyor. Since the small-sized bottle S is smaller than the gap G1, it falls down in the gap between the small-sized bottles S, and the conveyor 2, which also serves as the second-stage transport sorting machine,
21 and if the gap is smaller than the gap G2 between the conveyors 2 and 21, which are also used for carrying and sorting.
Between the conveyors 3 and 31, which are located below the conveyors 3, 31 which are also used for transport and sorting. Then, the size of the bottle S is determined by the conveyors 3 and 31 which are also used for conveying and sorting.
If the gap G3 is larger than the gap G3, it is carried out by this conveyor. If the bottle S is smaller than the gap G3, the bottle S further falls through the gap and is carried out by the conveyor 4 dedicated to conveyance.

As described above, the gaps G between the pair of conveyors 1, 11, 2, 21, 3 and 31 are also used.
1, G2, and G3 have a sorting function of at least three sizes, large, medium, and small, depending on the size of the collection bottle, and the smallest collection bottles smaller than this gap sequentially fall downward from this gap. The very small bottle is transported to a predetermined position by a transport conveyor 4 dedicated to transport located at the lowest position.

Further, gaps G1, G2, G between a pair of conveyors 1,11,2,21,3,31 which are also used for sorting.
3 can be applied to the sorting and transport of bottles of various sizes if it can be adjusted wide or narrow.

Next, another embodiment will be described with reference to FIG. The purpose of this embodiment is to prevent breakage of the material which is easily broken during sorting. It is to be noted that the same reference numerals are given to components having substantially the same structure as the above-described embodiment. According to the present invention, buffer plates 5 and 51 are provided in the upper and lower gaps between a pair of conveyors 1,11,2,21,3,31 which are installed in three stages and are also used for sorting. It is provided so as to protrude into G1, G2 and G3. Therefore, the bottle S comes into contact with the buffer plate while falling from the upper conveyor to the lower conveyor, and the speed of the drop is reduced, so that breakage during sorting can be prevented.

In all of the above-described embodiments,
The speed of conveyors 1, 11, 2, 21, 3, 31, 4 is
It is not limited to a fixed one, but includes one with a variable speed.

[0014]

According to the present invention, since the conveyor for both sorting and transporting and the conveyor for exclusive use of transferring are installed in the vertical direction, the space efficiency of the installation space is improved. It is possible to sort by various sizes of collected bottles, etc. In addition, a pair of conveyors that also serve as sorting and sorting are installed at a low slope inside each other, so collection bottles etc. can easily move into the gap And then
In the vertical gap between the pair of conveyors and sorting conveyors installed in a plurality of stages, a buffer plate is provided so as to protrude into the space between the conveyors and sorting conveyors.
Damage to the collected bottles during sorting can be prevented.
