The present invention relates to a furniture packaging device, and more specifically, to automatically package furniture by lifting and lowering furniture whose outer surface is wrapped with a cushioning material such as cardboard, and binding the upper, central, and lower parts of the furniture by banding them. It relates to a furniture packaging device configured to do this.

In general, furniture is packaged with a cushioning material such as cardboard wrapped around the outside and tied using a band to maintain the packaged state and prevent the package from unraveling.

However, in the past, the banding work to prevent furniture from being unpacked was done manually, which was not only very inconvenient and time-consuming, but also had the problem that the packaging was not secure.

In addition, it was very difficult to band furniture with high top and bottom heights, such as chests of drawers, dressers, bookshelves, etc., to prevent the packaging from unraveling (especially banding the upper part of the furniture). Therefore, for high furniture, it was difficult to lay it down. There was a problem that packaging work had to be done in this condition, so the packaging work was very cumbersome.

The present invention was devised to solve the above problems, and its purpose is to lift and lower furniture whose outer surface is wrapped with a cushioning material such as corrugated cardboard using a lift means, and then band the upper, central, and lower parts of the furniture through a bending means to package the furniture. The goal is to provide a furniture packaging device that allows this.

The object of the present invention is a frame consisting of a floor frame and a vertical frame installed vertically on both sides of the floor frame, a guide rod installed in the vertical direction on both front ends of the vertical frame, and a guide rod installed at the front end of the floor frame. A lifting plate is configured to seat furniture on which a cushioning material such as cardboard is wrapped on the upper surface, with both ends supported by the guide rod and configured to guide and move in the vertical direction, and is installed on the frame so that the lifting plate follows the guide rod.
