Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cleaning device for a collection bottle having a screw-on cap.

[Prior Art] Collection of empty bottles can be roughly divided into two types: collection with the cap removed and collection with the cap screwed on.

The former method is widely used for bottles filled with harmless substances, such as beer bottles and milk bottles, and various apparatuses for washing collected bottles are also in practical use.

On the other hand, the latter method is carried out on bottles filled with harmful substances, such as poison medicine bottles, but the collected bottles are cleaned manually.

[Problems to be solved by the invention] However, as the number of empty bottles gradually increased, manual cleaning became disliked and hygiene became a problem.

Therefore, we developed a fully automatic bottle washing device that can handle ``pickup from pallet'' → ``cap removal''.
There was a demand for the development of a bottle washing device that can automatically carry out the following steps: → "Discharge of residual materials" → "Washing" → "Return to the pallet".

The present invention has been devised by paying attention to such matters.

[Means for Solving the Problems] That is, the collection bottle cleaning device to which the cap is screwed according to the present invention includes a horizontal table body mounted so that it can be rotated intermittently in one direction, and the table body. Four bottle gripping chucks radially protrude from the body via an inversion return mechanism, and the chucks are sequentially moved from the bottle delivery position to the cap removal position;
an inversion/return mechanism control device that controls the inversion/return mechanism so as to invert the chuck at the residue ejection position and the cleaning position when the chuck is returned to the delivery position via the residue ejection position and the cleaning position; a bottle transfer device comprising a chuck opening/closing control device for separating the claws of the chuck at the bottle delivery position; a cap removal and recovery device for removing and recovering a cap screwed onto a collection bottle transferred to the cap removal position; ,
a residue collection means for recovering residue discharged from the bottle from which the cap has been removed and which has been transferred to the residue discharge position; and a residue collection means for recovering residue discharged from the bottle which has been transferred to the washing position and from which the residue has been discharged. A cleaning liquid injection and recovery device that injects cleaning liquid to the bottle and collects cleaning waste liquid, and a cleaning liquid injection and recovery device that receives the washed bottles transferred to the delivery position from the chuck and returns them to the pallet, and then screws the caps from the pallet. The present invention is characterized by comprising a bottle supply and return device that picks up collected bottles and supplies them to the chuck at the delivery position.
