The present invention relates to a bookbinding paper stacking device connected to an image forming apparatus such as a copying machine, and more particularly, a bookbinding paper stacking device for reducing the lifting phenomenon of the bookbinding tape portion of the bookbinding and the stacking of the bookbinding paper. To provide a structure.

In the conventional bookbinding paper stacking device installed in an image forming apparatus such as a copying machine, as shown in FIG. 1, the tray 10 is installed to be elevated along the side of the paper post-processing apparatus of the image forming apparatus 1, and the roller 6 It is configured to load the bookbinding paper 5 discharged through.

However, the bookbinding paper 5 is a form in which high temperature heat is applied in order to melt the adhesive attached to one side of the tape 5a in the bookbinding process, and when the bookbinding work is completed in the applied state, the bookbinding paper is cooled and the adhesion is completed. However, since the book bound in a state where the cooling is not completely performed is discharged toward the tray 10 through the roller 6, the cover surface 5b of the bookbinding paper swells or floats. Complete cooling can improve the adhesiveness of the tape, but the overall processing time is increased due to the increase of the waiting time for cooling, which makes continuous operation difficult, so the discharge operation is generally performed when the latent heat is not completely removed. The phenomenon that the cover surface 5b of the paper swells or is lifted is inevitable.

As shown in FIG. 1, when a plurality of bookbinding papers 5 which are discharged in a swelling or excited state are laminated on the tray 10 as shown in FIG. 1, the bookbinding papers 5 are illustrated in FIG. 2. Due to the difference in the lamination thickness between the front end and the rear end (the part bonded by tape) of the field, the alignment of the bookbinding paper 5 becomes unstable, and as the stacking height increases, the bookbinding paper on the upper side is pushed forward. A problem arises in that it is impossible to detect the correct stacking height of the stacked bookbinding paper.

In addition, when the bookbinding paper 5 is discharged while the cover surface 5b in contact with the tape 5a is swollen and the discharged bookbinding paper is cooled, the swollen state is fixed, so that the quality of the bookbinding state is fixed. There is a downside to falling.

The present invention has been made in view of the above problems, and an object thereof is to provide a structure of a bookbinding paper stacking device capable of improving bookbinding quality.
