Description

[Detailed Description of the Invention] The present invention is capable of cleaning products that are easily damaged by dents and scratches, and whose quality is therefore likely to be extremely degraded, such as vegetables and fruits such as potatoes and vegetables, without causing dents or scratches. The present invention relates to a feeding device that feeds articles to a loading surface in a container.

In general, a feeding system shown in FIGS. 1 to 3 is used to feed articles transported by a transporting means into a container or the like. In the feeding system shown in FIG. 1, a container 2 is simply placed directly below the discharge end of a conveyor 1, which is a conveyance means, and there is a large head difference between the discharge end and the loading surface of the articles 3 in the container 2. It has no adjustment function. For this reason, it is inevitable that the articles 3 fed into the container 2 will have dents, scratches, etc., and are usually used for articles that have been damaged.

The feeding system shown in FIG. 2 is an improvement on the feeding system shown in FIG.
The height difference between the discharge end and the loading surface is minimized depending on the amount of articles 6 filled.

The feeding system shown in FIG. 3 is also an improvement on the feeding system shown in FIG.
2), the height difference between the discharge end and the loading surface is minimized depending on the amount of articles 9 filled.

The feeding system shown in Figures 2 and 3 is the container 4, 8
This method takes into consideration the prevention of damage to the articles 6 and 9 to be fed into the container, but the feeding method shown in FIG. 2 is not very effective if the container 4 is deep, and the feeding method shown in FIG. If the height is slightly higher than the height of the container 8, the feeding method is the same as that shown in FIG. For this reason, when the products are vegetables and fruits such as potatoes and potatoes, it is undeniable that the two feeding methods will leave dents, scratches, etc. on the products.

In view of the above-mentioned problems of the article supply device, this invention includes an article conveyance means, a conveyor A that conveys the article inherited from this conveyance means, and a conveyor A that is arranged parallel to and above the conveyor A. It consists of a transport conveyor B in the form of an endless belt facing the transport conveyor A, and a large number of elastic fins are erected on the endless belt of the transport conveyor B, and the articles are transported between the transport conveyor A and the adjacent belt.
