Counting unit of sheet-shaped material

Abstract

Abstract PURPOSE: To make it possible to count very accurately sheet-shaped materials dependently upon an operation arm or a contact rod, by controlling the unit so that the distance where the contact of the contact rod is moved in the horizontal direction while being brought into contact with the detected material surface may be always fixed independently of the thickness of the detected material. CONSTITUTION: A folded sheet-shaped material is fed onto a main roller, and contact 7' at the tip of contact rod 7 is brought into contact with the tip of the detected material and is pushed away forward. According to this operation, operation arm 11 is rotated with axis 12 as the center; and when tip 11' breaks operation line 14' of contactless switch 14, a pulse is generated by a related pulse generator. Then, contact 7' is pressed upward and is hidden completely in slide groove 24 of slide guide face 20 of the main body. At this time, since pin 13 of operaion arm 11 is so set that pin 13 may be brought into contact with the upper end of vertical groove 10 of contact rod 7 independently of the thickness of the detected material, contact 7' is hidden in slide groove 24 as it is after that. Consequently, accuracy of pulse generation dependent upon switch 14 is always held because movement distance m of contact 7' in the horizontal direction is always fixed independently of the thickness of the detected material.
