Abstract

PURPOSE:To provide a sorter which eliminates the difference between the results of sorting by individual differences in charging operations, is simple in constitution, and utilizes weight differences by providing the sorter with a dropping section communicating with a feed port, a sorting plate freely rotatably supported in the lower part thereof and housing sections for heavy objects and light objects. CONSTITUTION:Charging of bottles, cans, etc., is executed by placing the charges on a horizontal part 4 of a charging operation section 3 and turning this horizontal part like the chain line by means of a knob part 7. As a result, the kinetic energy of the magnitude proportional to the weights of the charges are generated when the charges are sent and dropped to the dropping part 9. The pushing down force overcomes this energizing force, in the case of the heavy objects, such as bottles, and the sorting plate 12 is turned from a relation with the energizing force preset on a sorting plate 12, i.e., the turning moment by a weight 14. The charges are thus dropped into the lower housing section 15 for the heavy objects. The force enough to turn the screening plate 12 is not generated in the case of the light objects, such as cans, and these objects are dropped into the front lower housing section 16 for the light objects along the slope of the sorting plate 12.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting apparatus for separating heavy articles such as relatively heavy bottles and light articles such as relatively small cans.

[0002]

2. Description of the Related Art Conventionally, as this type of sorting apparatus, there have been known ones that perform sorting by utilizing various principles. For example, there are those that use magnetic force to sort, and those that use the difference in gravity of the sorting target to sort. The present invention relates to the latter sorting means utilizing the difference in gravity.
By the way, although the sorting means utilizing this gravity difference has a simple principle, there are still problems that the structure thereof becomes complicated and erroneous selection is caused due to the difference in the weight measurement state. For example, there is a drawback that the selection result is likely to be different based on individual differences regarding the insertion operation, that is, the individual differences between the person who inserts quietly and the person who inserts fairly often.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of such problems, and an object thereof is to eliminate the difference in the selection result based on the individual difference in the insertion operation, and An object of the present invention is to provide a sorting device that utilizes a weight difference with a simple configuration.

[0004]

The present invention, when applied to a storage device, has a structure in which an input port, a drop portion that is connected to the input port and forms a predetermined drop, and a slope below the drop portion. And a sorting plate rotatably supported by the box body in a state of being urged upward, and a container for a heavy object such as a bottle disposed below the sorting plate. And a container for a lightweight object such as a can, which is disposed below and in front of the selection plate. In addition, as a configuration when applied to an empty can compressor, a charging port, a dropping part continuous with the charging port and forming a predetermined head, and arranged obliquely below the dropping part and attached above the dropping part. A sorting plate rotatably supported with respect to the box body in a urged state, and an accommodating portion for heavy objects such as bottles is disposed below the sorting plate, and a lower front portion of the sorting plate. Is connected to the can introduction part of the empty can compressor.

[0005]

In the present invention, since the drop portion having a predetermined drop is formed between the charging port and the selection plate and the kinetic energy generated due to this drop is used for the selection operation, the operation is performed. Individual differences regarding operation are absorbed,
The influence on the selection result is blocked. Further, since the means for realizing the same is composed of a simple combination of the formation of the predetermined head and the inclined selection plate biased with the predetermined rotation moment, the structure is extremely simple.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic view of a main part showing an embodiment of the present invention. In the figure, reference numeral 1 is a box, and an inlet 2 is formed in the upper part of the front part of the box 1. The inlet 2 can also be formed on the upper surface of the box 1. A charging operation section 3 for charging operation is attached to the charging port 2. The charging operation section 3 is mainly composed of a horizontal section 4 on which a bottle, a can, etc. are placed, and a slant section 5 which is connected to the rear end of the horizontal section 4 and shields the charging port 2. . The inclined portion 5 is rotatably supported by a support shaft 6. At the front end of the horizontal part 4, a knob 7 is further provided to insert the opening 2 at the time of rotation.
An arc-shaped shielding portion 8 that shields is formed. In the figure,
Reference numeral 9 is a drop portion that forms a predetermined head that is selected according to the type of object to be sorted. The falling portion 9 is formed between the stopper wall 10 and the partition wall 11. A sorting plate 12 is provided below the drop portion 9. The selection plate 12 is rotatably supported by a support shaft 13. A weight 14 is attached to the tip portion, and the gravity of the weight 14 imparts a rotation moment adapted to the type of the selection target to the selection plate 12. As a result, the sorting plate 12 is tilted and is stopped while being in contact with the lower end of the partition wall 11. 15 in the figure
Reference numeral 16 denotes a storage portion for a heavy object such as a bottle, which is disposed below the selection plate 12, and 16 denotes a storage portion for a lightweight material such as a can, which is disposed below the front surface of the selection plate 12. Note that as the biasing means for the rotation moment with respect to the selection plate 12, spring means such as a spring can be used instead of the weight 14.

[0007] Therefore, a bottle, a can or the like is thrown in by placing the thrown thing on the horizontal portion 4 of the throwing operation portion 3 and rotating it like a chain line through the knob portion 7. . By this throwing operation, when the thrown object is sent to the dropping section 9 and falls, the drop difference is constant, so that kinetic energy of a magnitude proportional to the weight (mass) of the thrown object is generated in the thrown object. Therefore, in the case of a heavy object such as a bottle, the pushing-down force due to the kinetic energy based on the weight is better than the biasing force set in advance for the selection plate 12, that is, the rotational moment of the weight 14. Since the sorting plate 12 is swiveled and rotated, the input material falls into the lower housing portion 15. In this case, the sorting plate 12 is configured to stop the rotation within a certain range by an appropriate stopper portion (not shown). Further, in the case where the input material is a lightweight material such as a can, the rotational moment for urging the selection plate 12 is larger, and the selection plate 12 cannot be rotated. Along the 12 slopes,
It falls into the accommodation portion 16 below the front. From the above,
Accurate selection can be performed without being affected by individual differences regarding the input operation.

The above sorting device is arranged above the can introducing portion of a known empty can compressor so that a heavy object such as a bottle which is not suitable for the compression process can be used as a pretreatment for the empty can compressor. Can be used as a means for excluding. That is, if the empty can introducing unit is connected to the lower part of the front side of the sorting plate 12 instead of the accommodating part 16 and the empty can compressor is connected, heavy objects such as bottles which are not suitable for compression processing are accommodated in the accommodating part 15. The empty empty can is introduced into the compression section of the empty can compressor through the can introducing section. Then, the empty cans sent to the compression unit via the empty can introduction unit are sorted into steel cans and aluminum cans by a known magnetic sorting means or the like after the compression processing, and are stored therein.

FIG. 2 is a schematic view of the essential portions showing another embodiment of the present invention. This embodiment is characterized in that a fixed inclined plate 17 is arranged on an extension of the selection plate 12 of the above-mentioned embodiment, and a magnet 18 for selecting an aluminum can and a steel can is attached to the tip of the fixed inclined plate 17. Have. Correspondingly, the storage portion 16 for the lightweight object is divided into a storage portion 16a for an aluminum can and a storage portion 16b for a steel can.

However, when throwing in bottles and cans,
As in the case of the above-mentioned embodiment, when the input material is placed on the horizontal portion 4 of the input operation portion 3 and rotated like a chain line through the knob portion 7, in the case of a heavy object such as a bottle, Since the pushing down force due to the energy of the movement based on the weight overcomes and rotates the sorting plate 12, the input material falls into the accommodation portion 15 below. Also, if the input is a lightweight product such as a can,
It is not possible to rotate the sorting plate 12, and the input material rolls down along the inclined surface of the sorting plate 12. Up to this point, the process is similar to that of the above-described embodiment, but in this embodiment, aluminum cans and steel cans are further sorted and accommodated. That is, the input material that rolls down along the slope of the selection plate 12 further rolls on the inclined plate 17, and in the case of an aluminum can, the magnet 1
Since it is not affected by No. 8, it falls into the housing 16a for the aluminum can at the lower front. On the other hand, in the case of steel cans,
The magnets 18 are attracted and attracted in the falling direction, or are attracted to the magnets one after another and sequentially fall into the steel can housing portion 16b. In this case, since the horizontal force acting on the can is also generated by the slopes of the selection plate 12 and the inclined plate 17, it is not affected by the charging operation.
The selection by the magnet 18 is accurately performed. From the above, without being affected by individual differences regarding the input operation,
At the same time as accurate sorting of heavy items such as bottles and lightweight items such as cans is performed, sorting of aluminum cans and steel cans is also performed accurately. It is also possible to extend the other end of the selection plate 12 and attach a magnet to the tip end thereof so as to also serve as a weight.

[0011]

According to the present invention, the following effects can be obtained based on the above constitution. (1) Since a drop portion having a predetermined drop is formed between the input port and the selection plate, and the selection operation is performed according to the magnitude of the energy of motion generated based on this drop, the individual difference regarding the input operation Are absorbed and the influence on the selection result is blocked. Therefore, an accurate sorting operation can be easily obtained. (2) Moreover, since the structure for that purpose is composed of a simple combination structure of a falling portion having a predetermined head and an inclined sorting plate biased with a predetermined rotation moment,
It's very easy. (3) As a pretreatment of the empty can compressor, it is also effective as a means for excluding heavy objects such as bottles that are not suitable for the compression treatment.
