Definitions

  • the invention is related to mechanical means for airing stacks of newly printed sheet material to prevent sticking and smearing of the printed text.
  • the apparatus comprises a base for supporting the stack with the sheets positioned vertically and a sheet-lifting means having a ridge is moved under the stack in order to move the sheets in relation to each other. The sheets may also be vibrated.
  • the method comprises disposing the stack on an approximately horizontal base, in such a manner that the plane of the sheets is in approximately vertical position, and the stack is thus supported with the sheets endwise such that it is capable of expanding somewhat in longitudinal direction during the operation.
  • the lower edges of the sheets which rest upon the base are then acted on by one or more sheet lifting members which, during movement along the stack, raise the sheets in relation to one another so that there occurs a displacement among the sheets which prevents adhesion.
  • the lifting apparatus may be constructed in many ways; it may for instance be in the form of a ruler the cross section of which in both lateral directions inclines upwardly toward a thicker central portion. If such a ruler is mounted parallel to, and in contact with, the lower adges of the sheets, and guided on a fixed base in a direction transverse of the lower edges of the sheets, the sheets will be raised by the leading edge of the ruler successively above the thick portion of the ruler and slide downwardly again toward the base when the downwardly inclined rear trailing edge of the ruler has passed.
  • Such a lifting member may have a reciprocal movement, or a plurality of such rulers may, for instance, be mounted on an endless belt which runs over rollers mounted in 3,418,725 Patented Dec. 31, 1968 the base.
  • a thin flexible band of metal or other suitable material may be disposed between the sheet lifting member and the sheets, upon which band the sheets rest. When the ruler is moved beneath this band the weight of the sheets will press said band against the ruler so as to raise and lower the sheets in accordance with the contour of the ruler.
  • the cross sectional form of the sheet lifting member may be varied, and an advantageous solution is to form the top portion of the ruler as a roller which greatly reduces the friction against the band when rolled against the underside thereof.
  • the base, or portions of the base, upon which the sheets rest or are supported, or even the actual lifting member may be subjected to vibration.
  • a further advantageous effect may be achieved by subjecting the sheets in the stack to compressed air which is directed to one or more of the edges of the sheets to force air in between said sheets.
  • FIG. 1 is an elevational view showing an embodiment of the apparatus with the stack of sheets in position on the base.
  • FIG. 2 shows the same in partial section along the line IIII in FIG. 1.
  • FIG. 3 shows the lifting member with the vibrator and conveyor, in partial section along the line III-III in FIG. 4.
  • FIG. 4 shows the same in partial section along the line 1VIV in FIG. 3.
  • FIGS. 1 and 2 show the most important members of the apparatus in the preferred embodiment example disposed upon a base 19 and comprising a framework 1 having a rigid end plate 12 and side Plates (not shown) for guiding the sheets of the stack 11, and also a movable end piece 13, together with the members, mounted in and on the frame, such as a reciprocally moving bogie 4 which carries the sheet lifting members 3 with its vibrator means 5, 6, 7 and 23, further, guide rods 9 and a motion screw 8 with motor 20, together with the flexible band or web 10 and the base plates 2 thereof, supported in the frame by the angle irons 22.
  • a reciprocally moving bogie 4 which carries the sheet lifting members 3 with its vibrator means 5, 6, 7 and 23, further, guide rods 9 and a motion screw 8 with motor 20, together with the flexible band or web 10 and the base plates 2 thereof, supported in the frame by the angle irons 22.
  • the apparatus is mounted pivotally on the base 19 about bolts 18 and, by means of a pressure cylinder 16 and connection 17, may be pivoted from horizontal to vertical position, as indicated by broken lines to the right in FIG. 1.
  • the sheet stack 11 arriving from the printing machine after the necessary waiting time, are driven on a platform or the like 15 and disposed upon the end plate 12 of the apparatus and the movable end piece 13 is lowered onto the top of the stack.
  • the sheet lifting member or the cross bar 3 being disposed previously in its end position in the left hand end portion of the frame in accordance with the drawing.
  • the stack 11 is then pivoted to the horizontal position shown in FIG. 1, and the end piece 13, is adjusted with sufficient clearage between said end piece and the stack so as to allow the stack the necessary freedom of movement.
  • FIGS. 3 and 4 show in greater dimension the barshaped lifting member 3 which is mounted on two spring loaded bolts 5, which are mounted vertically movable in a bogie or slide 4, which glides on guide rods 9 and is moved reciprocally by means of a motor driven screw 8.
  • a motor 7 On the trolley, bogie or slide 4, a motor 7 is further mounted, said motor driving a shaft 23 which, by means of eccentrics 6 imparts a rapid upward and downward movement to the spring loaded bolts 5, at the respected ends of the shaft 23, which causes vibration of the lifting member 3.
  • the sheet-lifting member 3 is illustrated as being provided with leading and trailing edges 3' which incline upwardly to the ridge as shown. These edges, of course, alternately become leading and trailing, depending upon the direction of movement of the sheetlifting member 3.
  • the bar shaped sheet lifting member 3 may also be divided into several parts. This also applies to the base plate 2.
  • the end piece 13 is shown with a pivotable end plate 14, the purpose of which is to permit the removal of one or more sheets, as necessary, during the operation.
  • a means 21 with a nozzle for the supply of compressed air is shown mounted above the stack at the location where the sheets are raised by the lifting member, and this apparatus is connected with the bogie 4, in a manner not shown, so that it accompanies the movement of the bogie and is at all times directly above the lifting member.
  • the object of this apparatus is to facilitate the seperation of the top portions of the sheets, and particularly aids the lowering of the sheets after the top portion of the lifting member has passed beneath them.
  • Method of aeration of a stack of printed sheets to prevent them from sticking together comprising positioning the stack on a support with the sheets substantially vertical and with their lower edges resting on the support, and successively acting on the lower edges of the sheets of the stack in a direction transverse thereto to successively raise the sheets, thus raising and lowering the sheets of the stack successively in relation to each other.
