The present invention relates to a cartoning machine, and more particularly to an insertion device of a cartoning machine for pre-bundling and transporting a predetermined number of articles to be stored in a packaging box.

[Conventional technology]

When a plurality of articles such as medicine packages are stacked and transported to the filling part in the packaging box, in order to perform stable transportation, conventionally, the articles are pressed from above by a pair of front and rear partition plates attached to the chain. The work clamp plate is assembled.

[Problems to be Solved by the Invention]

In the above conventional configuration, when the number of packages is changed, the height of the upper pressing plate assembled to each partition plate must be changed.

The present invention has been made to eliminate the above-mentioned drawbacks, and provides an insertion device for a cartoning machine using a single box (holder) for storing and transporting a package.

[Means for Solving the Problems]

The insertion device of the cartoning machine according to the present invention has a rectangular tubular shape with both ends open, and a pusher is inserted from one opening of a holder in which articles are stored and conveyed to the cartoning machine. The article inside the holder is pushed out from the other opening and inserted into the box body, and a concave portion is formed on the upper surface of the pusher, and an upper presser which can be vertically moved into the pusher and fitted into the concave portion. Means is provided, and a notch through which the upper pressing means can pass is formed on the upper surface of the holder, and the upper pressing means pushes out the article while pushing the article inside the holder while passing through the notch. It is the one.

[Action]

In the insertion device of the cartoning machine according to the present invention, when the articles stored and conveyed in the holder are transferred from the holder into the box (packing box), they pass through the notches on the upper surface and enter the holder. Since the upper pressing means integrated with the pusher is used to push the article while pushing the article,
Even an easily deformable article or the like can be reliably transferred from the holder to the box. Moreover, since the pusher is formed with a concave portion into which the upper pressing means can be fitted, even if the upper pressing means is lowered to a lower position, the pusher can press down the upper pressing means in order to firmly press the easily deformable article. There is no risk of interfering with the means.
