Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an apparatus for dispersing and supplying articles such as bottles and caps.

[0002]

2. Description of the Related Art Conventionally, there has been an apparatus for dispersing and supplying a large number of articles supplied from an article supply source to an article discharge conveyor by separating the articles from each other (dispersed supply) using an inclined conveyor with a lifting bar. The inclined conveyor with a lifting bar is inclinedly disposed between an article supply conveyor on the hopper side, which is an article supply source, and an article discharge conveyor, and lifts each of a plurality of positions spaced apart in a circumferential direction of the flexible conveyor. It has a crosspiece and is rotatable endlessly.
As a result, a large number of articles input from the article supply conveyor are lifted one by one or a small number by the lifting rail on the lower side of the inclined conveyor, and when the lifting rail reaches the uppermost position of the inclined conveyor, it is lifted. The dropped articles are dropped from the lifting bar and supplied to a lower article discharge conveyor.

[0003]

However, the prior art has the following problems. The inclined conveyor with a lifting bar has a gap between the lifting conveyor and the article supply conveyor to such an extent that the lifting bar does not interfere with the conveyor. This gap cannot be a large gap because the articles supplied from the article supply conveyor can be reliably transferred to the inclined conveyor. For this reason, there is a possibility that the article may bite into a relatively small gap that always exists between the article supply conveyor and the inclined conveyor with the lifting bar, and that the article may be damaged.

[0004] The inclined conveyor with a lifting bar is provided with a side plate for preventing the products from falling off the side of the conveyor in order to transport the articles picked up by the lifting bar to the top of the conveyor without dropping to the side of the conveyor. . For this reason, the lifting bar slides and moves on the side plate, and the article lifted by the lifting bar slides on the side plate or bites between the side plate, which may result in damage to the product. .

[0005] When there is a change in the type of the supply article, it is necessary to adjust the installation interval of the lifting bar and replace the lifting bar itself. At this time, it is difficult to attach / detach the lifting bar to / from the conveyor made of the flexible body, and it is necessary to replace every conveyor including the lifting bar, resulting in poor setup changeability.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to dispersely supply articles without increasing the risk of damage to the articles due to biting of the articles, and to improve the setup changeability corresponding to the change of article types.

[0007]

According to a first aspect of the present invention, there is provided an article distribution and supply apparatus for separating a plurality of articles supplied from an article supply source from each other and supplying the articles to an article discharge conveyor. A dispersion supply cylinder is disposed between the discharge conveyor and the dispersion supply cylinder, and the dispersion supply cylinder is provided with an article lifting blade at each of a plurality of positions spaced in the circumferential direction of the inner surface of the cylinder, and is rotatable around its own axis, Under the rotating state of the dispersion supply cylinder, an article supplied from the article supply source to the inner surface of the dispersion supply cylinder is scraped up by the article scraping blades of the dispersion supply cylinder at the cylinder lower side, and the article scraping blade is used to scrape the article. The lifted article is dropped from the article scraping blade on the upper side of the cylinder so that the article can be supplied to the article discharge conveyor.

According to the first aspect of the present invention, the following:
Has the effect of The articles can be reliably supplied to the inner surface of the dispersion supply cylinder provided with the article scraping vanes by simply dropping the articles from the article supply section on the article supply source side. Therefore, a large gap can be ensured between the inner surface of the dispersion supply cylinder and the article supply section on the article supply source side so that articles do not bite, and damage due to biting of articles can be avoided.

In order to prevent the articles lifted from the lower part of the cylinder to the upper part of the cylinder by the article-raising blades from dropping out of the cylinder, if necessary, the dispersed supply cylinder is provided with a side for preventing the article from falling off. The plate can be fixed. The side plate, which can be provided as required, rotates together with the dispersion supply cylinder, so that the article does not slidably contact or bite, thereby avoiding damage to the article.

[0010] Adjustment of the spacing of the lifting blades and replacement of the lifting blades themselves in accordance with the type of supply article are performed by attaching and detaching the lifting blades to and from the distributed supply cylinder.
At this time, the dispersion supply cylinder is made of a hard body, not a flexible body such as a conveyor, so that the scraping blades can be easily attached and detached and the setup changeability can be improved.
