Abstract

Disclosed is a stacker which can stack a lot of papers without folding or curling, even if a sheet of paper which is folded or curled is spread and inserted in it. Fig.1 shows the front view and side view of the stacker. A sheet of paper is spread and captured with rollers and kept inside the paper guide 3. When a pair of guides 3 is rotated as shown in the front view, a pair of side-weights 4 is rotated and pushed up with the upper plate of the guide 3. Then the weight 4 goes down to the position B finally, because the lower plate of the guide 3 has a slit which the weight 4 goes through as shown in the side view. The guide 3 and weight 4 always control the paper edge to prevent the folding or curling. Fig.2 is a front view and shows the initial condition of paper-capturing. A sheet of paper is captured in the guide 3. The bottom 8 is pushed up with the spring. When a pair of guides 3 is rotated as shown in Fig.3, the bottom 8 rises a little and the center guide 7 goes down with the movement of the plate 5 and link 6 to push the center of the paper. When the guide 3 is rotated moreover as shown in Fig.4, the weight 4 is pushed up with the paper 9. After the tip of the guide 3 goes away from the paper edge, the weight 4 goes through the slit and falls on the paper 9 as explained in Fig.1. When the guide 3 is rotated reversely as shown in Fig.5, the lower plate of the guide 3 pushes down the paper edge and the weight 4 is lifted up with the upper plate of the guide 3. Fig.6 shows the final condition of paper-stacking. The paper 9 and bottom 8 are pushed down with the guide 3 and the guide 7 is lifted up with the link 6. The stacker can stack a lot of papers without folding or curling by the repetition of a series of these movements. 1

Stacker for Papers with Folds or Curl

    Disclosed is a stacker which can stack a lot of papers without folding or curling, even if a sheet of paper which is folded or curled is spread and inserted in it.

Fig.1 shows the front view and side view of the stacker. A sheet of paper is spread and captured with rollers and kept inside the paper guide 3. When a pair of guides 3 is rotated as shown in the front view, a pair of side-weights 4 is rotated and pushed up with the upper plate of the guide 3. Then the weight 4 goes down to the position B finally, because the lower plate of the guide 3 has a slit which the weight 4 goes through as shown in the side view. The guide 3 and weight 4 always control the paper edge to prevent the folding or curling.

Fig.2 is a front view and shows the initial condition of paper-capturing. A sheet of paper is captured in the guide 3. The bottom 8 is pushed up with the spring. When a pair of guides 3 is rotated as shown in Fig.3, the bottom 8 rises a little and the center guide 7 goes down with the movement of the plate 5 and link 6 to push the center of the paper. When the guide 3 is rotated moreover as shown in Fig.4, the weight 4 is pushed up with the paper 9. After the tip of the guide 3 goes away from the paper edge, the weight 4 goes through the slit and falls on the paper 9 as explained in Fig.1. When the guide 3 is rotated reversely as shown in Fig.5, the lower plate of the guide 3 pushes down the paper edge and the weight 4 is lift...
