Abstract

A hopper includes a receiving member having a guide surface that guides a non-flat strip-shaped sheet and a posture adjusting unit that adjusts a posture of the falling sheet and sends it to the guide surface, and a discharge unit that discharges the sheet. The posture adjusting unit may have a posture adjusting surface continuous with the guide surface and bent from the guide surface so as to form a ridge line at a boundary portion with the guide surface.

First claim

What is claimed is:

1. A hopper comprising:
a receiving member having a guide surface that guides a non-flat strip-shaped sheet and a posture adjusting unit that adjusts a posture of the sheet and sends the sheet to the guide surface; and
a discharge unit that discharges the sheet,
the posture adjusting unit having a posture adjusting surface that is continuous with the guide surface and is bent from the guide surface so as to form a ridge line at a boundary portion with the guide surface.

2. The hopper according to claim 1 , wherein
the ridge line is inclined with respect to an end portion of the guide surface on a side of the discharge unit in plan view of the guide surface.

3. The hopper according to claim 1 , wherein
the posture adjusting surface has a length that is longer than a width of the posture adjusting surface.

4. The hopper according to claim 3 , wherein
the posture adjusting surface decreases in width toward the discharge unit.

5. The hopper according to claim 1 , wherein
the receiving member has a restriction surface provided continuously with the posture adjusting surface on a side of the posture adjusting surface opposite to the guide surface being bent from the posture adjusting surface so as to form a valley line at a boundary portion with the posture adjusting surface, and restricting a position of the sheet.

6. The hopper according to claim 5 , wherein
the valley line is inclined with respect to an end portion of the guide surface on a side of the discharge unit in plan view of guide surface.

7. The hopper according to claim 6 , wherein
when an inclination angle of the ridge line with respect to the end portion is θ1 and an inclination angle of the valley line with respect to the end portion is θ2, θ1<θ2 is satisfied.

8. A cutting process device comprising:
a cutting unit that cuts a sheet base material to form a non-flat strip-shaped sheet; and
a hopper including
a receiving member having a guide surface that guides the sheet and a posture adjusting unit that adjusts a posture of the sheet and sends the sheet to the guide surface, and
a discharge unit that discharges the sheet, wherein

the hopper is installed at a position in which the sheet formed by the cutting unit falls and one end portion of the sheet abuts on the posture adjusting unit.
