Abstract

A main object of the invention is to provide a sheet material separation-aiding apparatus that ensures that there can be a gap produced stably between a specific sheet material from a stack of sheet materials and a sheet material just below it, and that achieves size reductions, reduced energy consumptions and a decreased parts count. As shown in FIG. 4, the sheet material separation-aiding apparatus 1 comprises a rotating means 2 including an abutment portion 21 that is capable of coming in abutment on an end of the uppermost sheet material 101, a supporting means 3 that supports the rotating means 2 in a rotatable manner and is capable of moving in a vertical direction, a biasing means 4 that biases the supporting means 3 in a downward direction, and a lifting means 5 that lifts up an end 23 of the rotating means 2 in opposition to the abutment portion 21. As the end 23 is lifted up, it causes the rotating means 2 to rotate with the abutment portion 21 coming in abutment on the end of the sheet material 101, and as the end 23 is further lifted up, it causes the supporting means 3 and rotating means 2 to keep on going up while the rotating means 2 is kept from rotation by a counterforce that the abutment portion 21 receives from the sheet material 101.

Claims13

Dependent claims

A sheet material separation-aiding apparatus used in combination with a sheet material separator for separating a specific sheet material from a stack of sheet materials, characterized by comprising;

a rotating means including an abutment portion that is capable of coming in abutment on an end of said specific sheet material,
a supporting means that supports said rotating means in a rotatable manner and is capable of moving in a vertical direction,
a biasing means that biases said supporting means in a downward direction, and
a lifting means that lifts up an end of said rotating means in opposition to said abutment portion,
wherein said sheet material separation-aiding apparatus comprises, in order from said stack of sheet materials, said abutment portion, a center of rotation of said rotating means and the end of said rotating means in opposition to the abutment portion,
when the end of said rotating means in opposition to the abutment portion is lifted up, said rotating means rotates with said abutment portion coming in abutment on the end of said specific sheet material, and
when the end of said rotating means in opposition to the abutment portion is further lifted up, said supporting means and said rotating means keep on going up while said rotating means is kept from rotation by a counterforce that said abutment portion receives from said specific sheet material, whereby there is a gap between said specific sheet material in said stack of sheet materials and a sheet material below it.
