Definitions

  • ABSTRACT A device for delivering thin sheetlike items, such as vouchers, checks, or bills, to a stacker while giving the items a stiffening curvature about at least one axis extending in the conveying direction, the degree of curvature depending on the thickness of the sheet and being sufficient for the stacking process without producing an unacceptable degree of permanent deformation.
  • the present invention relates to a conveying device associated with a stacker for thin sheet-type items which are to receive a stiffening curvature around at least one axis of curvature extending in the conveying direction, the curvature being imparted by two laterally offset guide elements acting on the item at one side thereof and one central guide element acting on the item from the other side thereof and extending between the two laterally offset guide elements.
  • the guide elements to the one side of the item and those at the other side are movable relative to one another and a spring force is effective therebetween.
  • a conveying device having these features is disclosed in French Pat. No. 1,160,003. That patent discloses lateral guide elements formed by two discs of a guide roller with which two discs of a counter roller coact. The two first-mentioned disc are connected by a cylinder having a smaller diameter and each sheet brought over those discs is pressed at its central zone against the cylinder by a narrow resilient tongue which is disposed at the other side of the sheet and between the discs.
  • a stiffening curvature around at least one axis extending in the conveying direction is imperative in the case of items having a very low inherent stiffness in order to enable the items to be properly and consistently stacked. Due to their lack of stifiness such items receive only a very slight permanent deformation as a result of having been curved. However, when such a device conveys items having a greater stiffness, and thus requiring a correspondingly lesser degree of additional stiffening, the inevitable curving prior to stacking, when the same curvature is imparted to all items, produces an undesirable, greater permanent deformation particularly after repeated passage of such stiffer items through processing equipment.
  • a primary object of the present invention is to overcome such drawbacks and difiiculties.
  • a further object of the invention is to closely adapt the curvature imparted to each sheet by a conveying device to the stifiness of the sheet.
  • a more specific object of the present invention is to provide a conveying device of the type discussed above in which, over a wide range of the inherent stifi'nesses, an optimum stiffening curvature is imparted to each item undergoing the processing operation without producing an unacceptable degree of permanent deformation in any item.
  • FIG. 1 is an elevational, cross-sectional view, along the line II of FIG. 2, of a preferred embodiment of the invention for conveying items such as vouchers, checks, or bills.
  • FIG. 2 is a cross-sectional view along the line IIII of FIG. 1.
  • FIG. 3 is a plan view of certain elements of the conveyor according to the invention.
  • the illustrated stacker contains a stacking table I which is brought into a position which corresponds to the height of the stack formed by items 2, this being accomplished by any known controllable drive mechanism.
  • a stacking table I which is brought into a position which corresponds to the height of the stack formed by items 2, this being accomplished by any known controllable drive mechanism.
  • An arm 5 pivotal around an axis 4 rests on stack 2 and is provided with a lug 7 cooperating with an electric eye system 6 which cooperates with the control for the drive of the stacking table 1 to cause the stacking table to be lowered when, and as long as, the light beam of system 6 is obturated.
  • Conveying rollers 8 and 9 are disposed at the entrance of the conveying device of the stacker to guide the arriving items into the channel between two guide members 10 and 11. From there the items move onto a guide surface 12 and past two further pairs of rollers which are each formed by a guide roller 13 and a counter roller 14.
  • the guide surface 12 is provided with lateral recesses 15 to permit passage of counter rollers 14 as can be seen particularly in FIG. 2.
  • the intended axis of curvature of the items is disposed approximately along their center and the guide plate 12 is provided with a crease 12' which constitutes the previously men tioned center guide element and which is centered on such axis of curvature.
  • the lateral guide elements disposed to both sides of the axis of curvature are formed by a two-part bending spring 16 which is fastened to the guide member 11 and which forms a bar, or loop, 16' at its front end which rests, in the inactive position shown in FIG. I, on arm 5. In this position it passes through two further slits, or notches, 17 disposed in the end of guide surface 12 and shown in FIG. 2.
  • supporting elements which are constituted by the areas 12" of guide surface 12 which are symmetrically disposed to both sides of the crease l2 and, partially, also by the counter rollers 14.
  • the position of the items is additionally determined by the guide rollers 13 which act on the items from the same side as spring 16.
  • a further guide element 12" is also disposed in the edge area of the items following the supporting elements 12" and is also formed by a part of the guide surface 12.
  • a conveying device for conveying thin sheet-type items while imparting to such items a stiffening curvature about at least one axis of curvature extending in the conveying direction, which device includes two laterally offset guide elements acting on the items from one side thereof and one central guide element acting on the items from the other side thereof and disposed between the two laterally offset guide elements, a spring force being effective between the guide elements at one side and the other of the central guide element and the guide elements being movable with respect to one another, the improvement comprising supporting elements disposed to the outside of said laterally offset guide elements, said supporting elements being immovable with respect to said central guide element and being positioned with respect thereto for establishing a fixed item bending height which is determined by the distance between the item contacting surfaces of said central guide element and said supporting elements so that this height remains constant for items of any stifiness, and wherein the spring force is set for producing a curvature of each items at said central guide element as well as a reverse curvature at said laterally offset guide elements, the spring
  • central guide element is constituted by a creased portion of a guide member and there are two supporting elements constituted by outer regions of said guide member, which regions are symmetrically disposed with respect to said creased portion, and wherein said laterally offset guide elements are constituted by a two-part bending spring.
  • An arrangement as defined in claim 3 further comprising counter rollers each cooperating with a respective guide roller.
  • An arrangement as defined in claim 3 additionally comprising further outer guide elements disposed laterally to the outside of said supporting elements for imparting a further relatively flat curvature to the items in the vicinity of each said guide roller, the direction of such further curvature being the same as that of the reverse curvatures produced by said laterally offset guide elements.
