Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reversing device for reversing a container in order to remove bottles collected and collected from the container for recycling.

[0002]

2. Description of the Related Art When recycling bottles, households and the like throw the bottles into collection containers distributed by local governments in each town. Containers that have collected bottles are regularly collected at processing facilities. In the processing facility, the conveyed containers were unloaded to a receiving yard by a forklift, and then inverted for each container to remove bottles from the containers.

Conventionally, the operation of inverting a container has been performed manually, but this requires a great deal of labor.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to automatically reverse a container from which bottles have been collected, and to reduce the labor required for processing bottles. Is to provide.

In this specification, bottles refer to recyclable waste, for example, living bottles (bottles that are reused as they are), empty bottles, empty cans, plastic bottles, and the like.

[0006]

In the reversing device for collecting and recycling containers according to the present invention, the conveyor has a forwardly extending transport path, and the transport path is constituted by a rear transport path and a front transport path. In the rear transport route, the container is placed in a stable position,
The rear transfer path and the front transfer path are formed so that the container that has moved from the rear transfer path to the front transfer path falls sideways from the front transfer path, and has a guide rail that guides the falling container to reverse. It is what is being done.

In the reversing device for collecting containers for recycling containers according to the present invention, when the container is placed on the rear transport path, and moves from the rear transport path to the front transport path, the container falls laterally from the rear transport path and falls. Is guided by the guide rail and turned over. Therefore, the container in which the bottles are collected can be automatically turned over simply by placing it on the conveyor conveyance path.

Further, a container supporting member is arranged so as to be able to support the falling container, and the container supporting member is moved along the container falling path at a speed lower than the falling speed of the container due to its own weight. Then, since the container is moved at a speed lower than the falling speed due to its own weight while being supported by the support member, the falling speed of the bottles taken out of the container becomes slow, and the damage of the bottles can be prevented.

Further, the guide rail has an arc-shaped portion, and the center line of the arc-shaped portion extends in parallel with the transfer path of the sub-conveyor, and extends on the extension of the transfer path of the sub-conveyor.
A rotating body having a rotation center coaxial with the center line of the arc-shaped portion is arranged, and the container support member is projected from a plurality of locations that equally divide the rotating body in the circumferential direction, and is made to enter the container falling path. Accordingly, since the container moves along the arc-shaped portion and the support member is moved in parallel with the movement of the container, the falling container can be supported in a reliable and stable posture.

Embodiments of the present invention will be described below with reference to the drawings.

In the following description, the front and rear are defined as the front of the left side of FIG. 1 and the rear of the opposite side, and the left and right are defined as the left and right sides as viewed from the rear.

Referring to FIG. 1 and FIG. 2, there is shown a conveyor 11 on which a rectangular box-shaped top-opening container C which is long in front and back is loaded. The conveyor 11 includes a main conveyor 12 and a sub-conveyor 12.

The main conveyor 12 and the sub-conveyor 13 are both steel belt conveyors and have forwardly extending transport paths 14 and 15, respectively. The transport path 15 of the sub-conveyor 13 is connected to the front end of the transport path 14 of the main conveyor 12.

The main conveyor 12 is provided with an alignment guide 21. The sub-conveyor 13 is provided with a reversing guide 22 and a reversing assisting rotator 23. Further, referring to FIG. 3, the lower part of the reversing guide 22 is set as the start end of the transport path, and the bottle transport conveyor 24 is arranged so as to extend rightward from there. It is arranged to extend diagonally left and upward.

The transport path 14 of the main conveyor 12 is a container C
Has a width slightly wider than the width in the left-right direction. The container C is placed on the transport path 14 of the main conveyor 12 in a stable posture. The transport path 15 of the sub-conveyor 13 has a width slightly smaller than half the width of the transport path 14 of the main conveyor 12. The transport path 14 of the main conveyor 12 and the transport path 15 of the sub-conveyor 13 are connected so that their left edges are aligned. When the container C moves from the transport path 14 of the main conveyor 12 to the transport path 15 of the sub-conveyor 13, the container C falls and falls rightward from the transport path 15 of the sub-conveyor 13.

The alignment guide 21 is a conveying path of the main conveyor 12.
14 A pair of horizontal rod-shaped top guide rails 31 extending in the front-rear direction parallel to each other with an upper left and right space,
A pair of horizontal bar-shaped left and right side guide rails 32 extending in the front-rear direction with a vertical interval at both left and right edges of 14,
It consists of 33.

An interval corresponding to the height of the container C is formed between the transport path 14 of the main conveyor 12 and the top guide rail 31. An interval corresponding to the width of the container C in the left-right direction is formed between the side guide rails 32 and 33.
The left guide rail 32 extends to a position on the transport path 15 of the sub-conveyor 13. At the front end of the right guide rail 33, a bent portion 34 bent rightward by approximately 90 degrees is provided.

As shown in detail in FIG. 3 and FIG. 4, the reversing guide 22 is a pair of front and rear members which extend downward from the upper part of the conveying path 15 while being curved so as to project rightward from above the conveying path 15 of the sub-conveyor 13. Of the top guide rail 41,
A pair of front and rear bottom guide rails 42 extending substantially parallel to the top guide rail 41 from near the right edge of the transport path 15;
A pair of front end guide rails 43 extending in parallel at a distance from each other in a semicircular arc extending rightward from the front end of the transport path 15 and a right side guide rail 33 of the alignment guide 21.
And a pair of rear end guide rails 44 extending in a quadrant arc extending from the front end of the bent portion 34.

An interval corresponding to the height of the container C is formed between the top guide rail 41 and the bottom guide rail 42. An interval corresponding to the length in the front-rear direction of the container C is formed between the front end guide rail 43 and the rear end guide rail 44.

The top guide rail 41 has a semicircular portion 41a in the middle of its length. Front end guide rail
43 also has a semicircular portion 43a in the middle of its length. Top guide rail 41 and front end guide rail
The center O of each of the semicircular portions 41a, 43a of 43 is coaxial.

The rotator 23 is arranged near the front end guide rail 43 in front of the front end guide rail 43, and has a semicircular portion 41 of each of the top guide rail 41 and the front end guide rail 43.
a radial arm-shaped rotating plate 51 having a center of rotation coaxial with the center O of the a, 43a; It comprises three horizontal rod-shaped container support members 52 that pass between the rails 41 and enter the gap between the front end guide rail 43 and the rear end guide rail 44.

The bottle conveyor 24 is a belt conveyor. The empty container collection conveyor 25 is a crossed belt conveyor.

The main conveyor 12 and the sub-conveyor 13 are driven synchronously and continuously at the same speed. Depending on the driving speed of both conveyors 12, 13, the rotating plate 51 of the rotating body 23 is, for example,
8r. p. m. Rotating plate 51 at this speed
Is driven, the peripheral speed of the container support member 52 becomes 0.
It is on the order of 7 m / s, which is a rather slow speed.

The container C is transported on the transport path 14 of the main conveyor 12.
It is transported forward in a stable posture on the top. When the container C is transported to the front end of the transport path 14 of the main conveyor 12, the container C moves from there to the rear end of the transport path 15 of the sub-conveyor 13. At the beginning of the transfer, the container C is in a stable posture because it extends over the transport paths 14 and 15 of both the conveyors 12 and 13. When most of the container C approaches the transport path 15 of the sub-conveyor 13, the posture of the container C becomes unstable, and the container C eventually falls and falls to the right. Falling container C
Are turned upside down while being guided by the turning guide 22.

When the container C falls, the container C is received by any one of the container support members 52 and is inverted at the same speed as the movement of the container support member 52. As described above, the moving speed of the container support member 52 is:
Slow, which is much less than the free fall speed of container C due to its own weight.

When the container C is about to move on the transport path 15 of the sub-conveyor 13 and the container support member 52 is passing above the transport path 15, the front end face of the container C becomes the front end of the container support member 52. The container C does not enter the transport path 15 due to contact with the surface, which is in the way. The container C must wait there until the container support member 52 passes above the transport path 15. However, since the transport path 15 is formed of a steel belt, the container C The belt moves while slipping, and the container C can wait without any trouble. When the container support member 52 passes above the transport path 15, the container C enters the transport path 15 of the sub-conveyor 13 such that the container C enters between two adjacent container support members 52.

As the container C is turned over, the bottles are thrown out of the container C and fall. At this time, the falling speed of the bottles is slow enough to prevent cracking or the like due to the falling since the falling speed of the container C is low. The falling bottles are received by the bottle transport conveyor 24 and transported to a predetermined place.

When the empty containers C are taken out of the bottles and moved to the end of the moving path by the reversing guide 22, they are taken up by the empty container collecting conveyor 25.
While being conveyed by the empty container recovery conveyor 25, the container C is sprayed with washing water, and after washing, the container C is provided for reuse.

In the above description, the conveying path of the conveyor is constituted by the rear conveying path and the front conveying path. Instead, the conveying path is constituted by the left conveying path and the right conveying path. When the length of the transport route and the length of the front transport route are combined into a long transport route, the length of the right transport route is a short transport route that is only the length of the rear transport route, and the containers are placed on the left and right transport routes. Alternatively, the container may be transported in a stable posture, and when the container is placed only on the left transport route, the container may be in an unstable posture and may fall from the left transport route.
