Description

the rollers 7 is carried out from the shaft 19, on which the rollers 6 are mounted, through one or more belt non-variation. In this case, the drive of the rollers 7 is made in such a way as to ensure the rotation of the rollers 7 in the direction opposite to the rotation of the rollers 6. The position of the levers 13: AND 14 is determined from the following conditions. The angle a, formed by the longitudinal axis of symmetry of the levers 73 and / 4 and the direction of movement of the sheets, is chosen so that jamming of the sheets and "jumping of the rollers 7" are avoided. If the angle o increases more than some given value, then the sheets are jammed. If the angle a decreases to a value lower than the set one, the rollers 7 begin to "bounce." The angle a is also a function of the coefficient of friction of the surface of the rollers 7, so that this angle can be increased by reducing the coefficient of friction, and vice versa.

The rollers 6 are made of an elastic material with a high coefficient of friction. The rollers 7 are made of a less elastic material than the rollers 6, and the coefficient of friction also makes up the coefficient of friction of the rollers 6. This ensures the promotion of the lower sheet and the delay of the upper sheet grabbed by the lower sheet when removing sheets from the bunker / bottom.

The device works as follows.

Bottom sheets placed into the hopper 1, one through the hole 2 in the wall 3 of the hopper, are directed to channel 5. Due to the inclined arrangement of the hopper and the curved bottom, the bottom sheets of the foot do not experience the vertical weight of the entire moan. In addition, as the sheets are removed from the hopper, some lower sheets, captured by the output sheet due to adhesion between the sheets, move outside and their rear edges, slipping along the plate 9, are freed from the weight of the back of the foot, which greatly facilitates the output of sheets from the bunker. The pad 10 of the roller 4 performs a dual purpose, one of which is used to shake a small group of bottom sheets to exfoliate them from each other, and the other to grip the bottom sheet. The sheet removed from the hopper 1 by the roller 4 enters the rollers 5 and 7, which give it a wave-like shape, increasing its rigidity in the longitudinal direction and the force of adhesion of the sheet to the rollers 6. Due to the difference in the coefficients of the rollers 5 and 7 and their rotation in opposite directions If two or more sheets are taken out of the bunker, the upper sheets are delayed and only one sheet is removed from channel 5. Depending on the degree of stiffness of the sheets, the relative position of the rollers 6 and 7 can be changed by moving them along the axis of rotation.

The use of the described device makes it possible to separate sheets of various formats, weights, and thicknesses from the foot with a high degree of reliability.
