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 take out bottles collected in a container for recycling.

[0002]

2. Description of the Related Art When recycling bottles, bottles from households are put into a collection container distributed by each municipality in each town. Containers that collect bottles are regularly collected at processing facilities. At the processing facility, the loaded containers were unloaded by a forklift into the receiving yard, and then inverted for each container to take out bottles from the container.

Conventionally, the work of inverting the container has been performed manually, but this was a labor-intensive work.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to recycle a bottle collecting container reversing device capable of automatically reversing the container in which the bottles are collected and saving the processing of the bottles. To provide.

[0005] In this specification, bottles refer to recycled resources such as living bottles (bottles that can be reused in the form of bottles), empty bottles, empty cans, PET bottles, and the like.

[0006]

In the recycle bottle collecting container reversing device according to the present invention, the conveyor has a forwardly extending conveying path, and the conveying path is constituted by a rear conveying path and a front conveying path. In addition, the container can be placed in a stable posture on the rear transportation route,
The rear transport route and the front transport route are formed so that the container that has moved from the rear transport route to the front transport route will drop from the front transport route to the side, and a guide rail that guides the falling container to be reversed is provided. It is what has been.

In the container reversing device for collecting bottles for recycling according to the present invention, when the container is placed on the rear conveyance path and the rear conveyance path is transferred to the front conveyance path, the container falls sideways from the rear conveyance path and falls. Is guided by the guide rail and inverted. Therefore, it is possible to automatically turn over the container in which the bottles are collected by simply placing the container on the conveyor conveyance path.

Further, the container supporting member is arranged so as to support the falling container, and the container supporting member can be moved along the container dropping path at a speed slower than the falling speed due to the own weight of the container. Since the container is supported by the support member and is moved at a speed slower than the drop speed due to the weight of the container, the drop speed of the bottles taken out from the container is slowed and damage to the bottles can be prevented.

Further, the guide rail has an arcuate portion, and the centerline of the arcuate portion extends in parallel with the conveying path of the sub-conveyor, and on the extension line of the conveying path of the sub-conveyor,
A rotating body having a rotation center coaxial with the center line of the arcuate portion is arranged, and the container supporting member is projected from a plurality of places that equally divide the rotating body in the circumferential direction and is made to enter the container dropping path. In this case, the container moves along the arcuate portion and the supporting member is moved in parallel with the movement of the container, so that the falling container can be reliably supported in a stable posture.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

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

Referring to FIGS. 1 and 2, there is shown a conveyor 11 on which a rectangular parallelepiped box-shaped top opening container C having a long front and back is placed. The conveyor 11 is composed of a main conveyor 12 and a sub conveyor 12.

Each of the main conveyor 12 and the sub-conveyor 13 is a steel belt conveyor and has conveying paths 14 and 15 extending forward. The end of the transfer path 15 of the sub-conveyor 13 is connected to the front end of the transfer 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 an inversion guide 22 and an inversion assisting rotating body 23. Further, referring to FIG. 3, the bottle conveying conveyor 24 is arranged so that the lower side of the reversing guide 22 is the starting end of the conveying path and the bottle conveying conveyor 24 extends rightward from the starting end of the conveying path. It is arranged so that it extends diagonally upward to the left.

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

The alignment guide 21 is a transfer path of the main conveyor 12.
14 A pair of horizontal bar-shaped top guide rails 31 that extend in the front-rear direction in parallel with each other at an interval above and to the left and right
Horizontal bar-shaped left and right side guide rails 32 extending in the front-rear direction at a distance from each other on both left and right edges of 14,
It consists of 33.

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

As shown in detail in FIGS. 3 and 4, the reversing guide 22 is a pair of front and rear extending curvedly so as to be projected rightward from above the conveying path 15 of the sub-conveyor 13 and extending below the conveying path. Top guide rail 41 of
A pair of front and rear bottom guide rails 42 extending substantially parallel to the top guide rail 41 from the vicinity of the right edge of the conveyance path 15,
A pair of front end guide rails 43 extending in parallel to each other with a semicircular arc extending rightward from above the front end of the conveyance path 15 and a right side guide rail 33 of the alignment guide 21.
It is composed of a pair of rear end guide rails 44 which are continuous with the tip of the bent portion 34 and which draw a quadrant arc.

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

The top guide rail 41 has a semi-arcuate portion 41a in the middle of its length. Front end guide rail
43 also has a semi-circular arc portion 43a in the middle of its length. Top guide rail 41 and front end guide rail
The centers O of the respective semi-arcuate portions 41a and 43a of 43 are coaxial.

The rotating body 23 is arranged in front of and adjacent to the front end guide rail 43, and each of the top guide rail 41 and the front end guide rail 43 has a semi-arcuate portion 41.
Radial arm-shaped rotating plate 51 having a rotation center coaxial with the center O of a and 43a, and a rearward projecting position from a position that divides the circumference centered on the center of the rotating plate 51 into three equal parts. It is composed of three horizontal rod-shaped container support members 52 which pass through 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 recovery conveyor 25 is a belt conveyor with crosspieces.

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

The container C has a transfer path 14 of the main conveyor 12.
It is transported upwards in a stable posture and in a forward direction. When the container C is transported to the front end of the transport path 14 of the main conveyor 12, it 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 straddles the transfer paths 14 and 15 of both conveyors 12 and 13. When most of the container C approaches the transfer path 15 of the sub-conveyor 13, the posture of the container C becomes unstable, and eventually the container C falls to the right and falls. Container C falling
While being guided by the reversing guide 22, they are reversed upside down.

When the container C is dropped, it is received by one of the container support members 52 and is reversed 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 significantly less than the free fall velocity of container C due to its own weight.

When the container C is about to transfer to the transfer path 15 of the sub-conveyor 13, if the container support member 52 is passing above the transfer path 15, the front end surface of the container C will have the front end surface of the container support member 52. The container C abuts on the surface, which becomes an obstacle, and the container C cannot enter the transport path 15. The container C has to stand by there until the container support member 52 passes above the conveyance path 15. However, since the conveyance path 15 is formed of a steel belt, the container C is kept in a steel state with respect to the waiting container C. The belt moves while slipping, and the container C can stand by without any trouble. When the container support member 52 passes above the transfer path 15, the container C enters the transfer path 15 of the sub-conveyor 13 so that the container C enters between the two adjacent container support members 52.

As the container C is reversed, the bottles are thrown out of the container C and fall. At this time, the falling speed of the bottles is so slow that the container C does not drop or the like because the falling speed of the container C is low. The falling bottles are received by the bottle transfer conveyor 24 and are carried to a predetermined place.

When the empty container C is taken out of the bottles and moved to the end of the moving path by the reversing guide 22, the empty container collecting conveyor 25 picks it up.
Cleaning water is sprayed on the container C while being conveyed by the empty container recovery conveyor 25, and after cleaning, the container C is provided for reuse.

In the above description, the conveyor transport path is composed of the rear transport path and the front transport path, but instead of this, the transport path is configured of the left transport path and the right transport path, and the left transport path is rearward. When the length of the transport route and the length of the front transport route are set to a long transport route, the right transport route is set to the short transport route that is only the length of the rear transport route, and when containers are placed on both the left and right transport routes, The container may be transported in a stable posture, and when the container is placed only on the left transport path, the container may be in an unstable posture and the container may drop from the left transport path.
