Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an article for collecting and supplying individually packaged articles such as sheet seaweed or rice crackers from an individual packager to a subsequent accumulating packager as shown in FIG. Regarding the supply device.

Conventionally, the following ideas existed for accumulating a constant number of individually packaged articles and sending them to an accumulating packaging machine.

That is, as shown in FIG. 7 of the embodiment, first and second conveyors 1 and 2, which are arranged in series with different levels, are arranged between an individual packaging machine and an integrated packaging machine.

However, this cannot keep up with this type of integrated packaging machine whose capacity has been increasing significantly in recent years.

The first conveyor 1 carrying the lid and carrying the articles individually
Since a fixed number of articles are accumulated and transferred from the first conveyor to the second conveyor 2, the second conveyor 2 must be stopped intermittently until the accumulation is completed. There is a theory that the delay due to intermittent stoppage can be compensated for by rapid acceleration during driving, but this is especially true for brittle, flexible, and easily collapsible items, where the influence of inertia is large and some items may shift position. , damage occurs, and some objects collapse.

Therefore, no matter how good the individual packaging machine is, efficient production cannot be achieved using conventional article supply devices.

The present invention focuses on and solves this problem. In short, by not directly moving the articles from the first conveyor to the second conveyor, but by bending the accumulated articles to the side through a sorting device and then placing them on the second conveyor, the conventional method is improved. The second conveyor, which has the same speed as the second conveyor, has substantially twice the conveying capacity.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.
