TECHNICAL FIELD OF THE INVENTION
The present invention relates to a bottle processing facility that removes bottles collected in a case for recycling from the case, prepares for sorting work in a later process, and cleans the case for reuse, etc. .
[0002]
[Prior art]
Recycling of resources, including bottles, has been even more pronounced recently with the enforcement of the Containers and Packaging Recycling Law in April 1997.
[0003]
When recycling bottles, bottles from households are put into collection cases distributed by local governments in each town. Cases where bottles have been collected are regularly collected in processing equipment. In the processing equipment, the carried-in case was unloaded to a receiving yard by a forklift, and then inverted every single case to remove bottles from the case. Conventionally, the operation of reversing the case has been performed manually, but this was an operation requiring a great deal of labor.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide a bottle processing equipment capable of automatically reversing a case in which the bottles have been collected and saving the processing time of the bottles. 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.
[0005]
[Means for Solving the Problems]

[0007]
A case conveyance conveyor is arranged at the end of the belt feeding side path of both belt conveyors in a horizontal posture so that the start end of the conveyance path can be connected, and the case conveyance conveyor can support the case upside down in a state of straddling the case. It has a pair of roller rows, and a gap is formed between the two roller rows so that bottles falling from the inside of the case upside down can pass through, and a case cleaning device is provided along the transport path of the case transport conveyor. When the case is arranged, when the case in the inverted posture is discharged onto the case transport conveyor from between the two belt conveyors, the case is received by both roller rows of the case transport conveyor, and bottles falling from inside the case are discharged by the two roller rows. The case and the bottles are separately sorted to pass through the gap between them, and the sorted case is washed by the washing device. The transport path start end of the bottle transport means faces between the two roller rows, a bottle passing resistance member is arranged in the middle of the transport path, and the bottle transport means is inclined along the transport path. It has a bottle-shaped sliding guide plate, and the bottle passing resistance member is constituted by a chain suspended so as to hang down on the bottle sliding guide plate, and an elastic tube covered by the chain. In this case, the bottles passing between the two roller rows fall along the bottle sliding guide plate, contact the bottle passing resistance member on the way, and the falling speed is reduced. Cracks can be prevented.

[0027]
Now, the power roller conveyor 22 is being driven, and the stopper 24 is lying down. The reversing conveyors 32 of the reversing device 12 have their respective feed-side paths in a horizontal posture, and are in a standby state with the belt 48 operating. There is no case C on the belt 48.
[0028]
When the case C is placed on the power roller conveyor 22, the case C passes over the power roller conveyor 22 and is fed between the reversing conveyors 32. When the second sensor 34 detects the fed case C, the reversing conveyor 32 is stopped, and the stopper 24 is raised.
[0029]
When the reversing conveyor 32 is stopped, the reversing frame 31 is subsequently rotated by 180 degrees. When the motor 55 is operated to rotate the drive shaft 51, the reversing frame 31 is rotated by the drive gear 54 and the chain 44. Due to the rotation of the reversing frame 31, the case C is also rotated together with the two reversing conveyors 32, and the case C is turned upside down with its opening facing downward.
[0030]
When the reversing frame 31 is rotated by 180 degrees, the proximity switch 49 detects this, the rotation of the reversing frame 31 is stopped, and the reversing conveyor 32 is restarted. As a result, the upside down case C is discharged from between the two reversing conveyors 32, and the discharged case C is placed on the transport conveyor 13.
[0031]
The next case C is placed on the power roller conveyor 22, and when this is detected by the first sensor 25, the power roller conveyor 22 is stopped.
[0032]
When the third sensor 62 detects the case C on the conveyor 13, the stopper 24 is lowered and the power roller conveyor 22 is restarted. As a result, the next case C is sent from the power roller conveyor 22 to between the two reversing conveyors 32.
[0033]
On the conveyor 13, only the case C is received by the two roller rows 61 and is conveyed forward, while the bottle B in the case C falls through between the two roller rows 61. The case C having discharged the bottle B is transferred from the transport conveyor 13 to the cleaning conveyor 71, and while being transported on the cleaning conveyor 71, the cleaning water is injected from the nozzle 78 to be cleaned. The cleaned case C is moved from the cleaning conveyor 71 to the carry-out conveyor 15, and then is conveyed to a storage yard by a free conveyor (not shown).
[0034]
On the other hand, the bottle B dropped from the case C is guided to the sliding guide plate 64 by the chute 63, falls along the sliding guide plate 64, and is put into a receiving hopper (not shown). While the bottle B falls along the sliding guide plate 64, the bottle B passes through the bottle passing resistance member 65 in many stages, so that the falling speed of the bottle B is reduced, thereby causing the bottle to break. Is prevented, and the sorting by the size and the sorting of the colors of the bottles performed in the post-process are facilitated.
[0035]
