Definitions

  • the invention relates to a device for guiding postal articles, forms or the like, to which said postal articles, forms or the like are offered in piles in order to be taken from the piles one by one and guided further sequentially.
  • a device for guiding postal articles, forms or the like In feeding postal articles, forms, transfers, banknotes, etc. to sorting-machines, stamping-machines, adding-machines, etc., it is ditficult to deliver only one document at a time from the pile to be treated to the relevant machine.
  • existing systems it happens that two or more documents stick together and are offered to the relevant machines together.
  • a roller or cylinder which has a slippin coupling with the driving-mechanism of a belt against which the postal articles, forms, or the like are pressed, and against which belt said roller also is pressed elastically.
  • the belt acts on the first document of the pile and moves it forward between said belt and roller.
  • the direction of movement of the circumference of the roller is determined by and is the same as the direction of movement of the belt at that place. If there is more than one document between the roller and belt, the direction of movement of the roller is determined by the driving-mechanism and is opposite to the direction of movement of the belt. Thus, any surplus or extra document is guided in a direction contrary to the direction of movement of the belt, and the document stopped will not be guided further until the preceding document has passed the additional roller.
  • FIG. 1 is a schematic diagram of one form of prior art device for removing flat articles by belts from a stack of such articles;
  • FIG. 2 is a schematic diagram of another form of prior art device for removing flat articles by belts from a stack of such articles, including the employment of a reversely driving roller adjacent the stack or pile of articles and the take-off belt;
  • FIG. 3 is an enlarged schematic diagram of a device according to this invention showing the normal operation of the device
  • FIG. 4 is an enlarged schematic diagram similar to that of FIG. 3 showing the return of an additional flat article which has been removed from the stack or pile by the belt;
  • FIG. 5 is an enlarged perspective view of a device according to the diagrams of FIGS. 3 and 4 for guiding postal letters, one at a time;
  • PEG. 6 is a vertical sectional view of the slipping coupling and roller adjacent the pile or stack of articles opposite the take-off belt.
  • FIG. 1 A Well-known prior art system is illustrated in FIG. 1.
  • A, B, C and D are transport rollers driven in the direction shown and moving conveyor belts S and T in the direction shown. Documents put in at A will be delivered sequentially at C in a manner as shown.
  • Z represents a pile of documents guided and stacked against a partition P and pushed with a force K against roller A.
  • belt S When moved by roller A, belt S will slip documents from pile Z and feed them at A between the belts S and T, Where they are conveyed further.
  • FIG. 2 Another and improved prior art system is as shown in FIG. 2.
  • an additional roller E has been provided, which is driven in the oppisite direction, but with a smaller circumferential velocity than the belts S and T. If now two or more documents get between belt S and roller B, only the document lying against the belt S is moved further, the others being returned to the stack or pile Z or stopped from movement until the upper documents are moved on one at a time by belt S.
  • FIGS. 3, 4 and 5 illustrate the system according to the invention.
  • F denotes the roller which is coupled by a slipping coupling to the driving-mechanism of the conveyor belt S.
  • FIG. 4 illustrates the situation in which two documents Lil and L2 are found between belt S and roller F.
  • the direction of rotation of roller F is determined by the driving-mechanism of the belt and the direction of movement of the circumference of roller F V is opposite to the direction of movement of belt S.
  • the first document Ll moves to the right due to a force exercised on it by belt S.
  • the second document L2 moves to the left due to a force exercised on it by roller F.
  • the first document L1 exercizes another force on the second document, L2 due to which the latter has a tendency to move to the right.
  • the force exercised on it by the roller is larger than that exercized on it by the first document. So the first docu ment will move to the right, the second to the left.
  • the second document L2 is only moved to the right by belt S after the first document Ll has passed roller F.
  • roller F When there is only one document between belt S and roller F (see FIG. roller F is no longer directly coupled with the belt. Two forces act on roller F then. One of them is the force exercised on it by the passing document, due to which the circumferential direction of the roller will be the same as the direction of movement of the belt at that spot. The other one is the force exercised by the driving-mechanism of the belt, due to which a force will be exercised in the circumferential direction of the roller, contrary to the direction of movement of the belt at that spot.
  • the coupling of F with the driving-mechanism of the belt is a slipping coupling, due to which the latter force will be a minimum with respect to the first, so that the documents will not be damaged.
  • FIG. 6 illustrates the principle of a slipping coupling.
  • 3 designates the roller F, a rubber roller mounted on a shaft 4. This shaft is coupled via a felt disc 5 with a driving-shaft 6. The latter shaft is driven by a string or belt ll via a driving wheel 2.
  • the shaft 4 can slip with respect to the shaft 6 due to the insertion of the felt disc 5.
  • the measure of slip can be adjusted by means of bolts 7 and 8, which can be screwed into the table 9 more or less, due to which the felt 5 is compressed more or less, respectively.
  • Device for feeding out, one by one, sheets (Z) of laminar material, which together form a stack said device comprising a positively driven conveyor member and a moveable friction member (F or 3) cooperating under pressure with the conveyor member (S), the cooperating parts of which members move along closed tracks and between which members the sheets are fed out, the direction of movement of the friction member being dependent on the possible presence between the friction member and the conveyor member of at least two superimposed sheets of laminar material (see FIG.
  • continuously operating driving means 1, 2 for the friction member including driving members and a slip clutch 5 between the driving members and the friction member, continuously tending to drive the friction member via the slip clutch, with a force which is always sufiicient to overcome the friction between two of the sheets of laminar material, in a direction opposite to the direction in which the friction member is influenced by the conveyor member.
  • roller means adjacent said pile pressed elastically against said belt means as it leaves said pile.
  • a device including means for urging said pile and belt means into friction contact with each other.
  • a device including means to retain said pile of flat articles separate from said roller means.
  • a device according to claim 2 wherein said flat articles include postal articles.
  • a device according to claim 2 wherein said flat articles comprise sheets of uniforms size and thickness.
  • a device including means for adjusting the degree of slipping of said slipping coupling means.
  • a device for removing postal articles, forms or the like, one at a time from a pile of said articles and guiding them sequentially along a path comprising:
