Definitions

  • ABSTRACT Related US. Application Data A movable carriage adjacent the input end of a stack postal documents having a pivoted spring-urged stacking head in contact with the stack, which head both feels and feeds the documents in the stack and operates a pair of micro switches on the carriage to move the carriage toward or away from the stack to maintain substantially the same pressure by the head on the stack regardless of the number of documents fed to or removed from the stack.
  • This invention relates to a stacking-device for temporarily storing postal documents, such as letters and the like in an intermediate stack, with a view to further automatic treatment.
  • Conventional intermediate stacking-devices of this type possess a carriage allowing the'introduction of the letters and their formation into a stack.
  • the letters must be supported to prevent them from falling over.
  • the carriage must keep the letters upright; while at the removing end this is done by the removing device. If the length of the stack does not exceed about 20 centimeters a minimal pressure will suffice to support the stack, but if the stack has a length of more than 30 centimeters the stack pressure required to prevent the stack from falling becomes inconveniently large necessitating a different adjustment of the pressure of the feeler against the incoming letters. In such a case the feeler not only determines the place of the letter, but also the stack pressure, and this larger stack pressure impedes the correct introduction and removal of the letters.
  • the stacking-device In order to distribute the stack pressure as favorably and as evenly as possible, the stacking-device according to this invention has a stacking-head pivotally mounted on a movable carriage, which head is kept in contact with the rear of the stack by a spring. In the normal state, of no supply and no removal, the stacking-head is kept in a state of equilibrium by the spring and its carriage stands still. However when documents are introduced into the stack, the stacking-head pivots backwardly out of its state of equilibrium until it closes a first contact, which starts a transport device to move the carriage backward until the stacking-head is returned to its state of equilibrium and the contact is opened to stop the carriage.
  • the carriage supports a very lightly hinged stacking-head instead of a feeling lever, which head always pushes with the same adjusted force against the stack, because it mainly reacts to differences of pressure arising during the stacking operations.
  • the position of the stacking-head determines whether the carriage must move, but the front of the stacking-head does not move with the carriage, it remains stationary while the spindle or pivot for the stacking head moves with the carriage, so that during movements of the carriage the pressure on the stack remains unchanged.
  • the pressure of the incoming letters against the stacking-head is practically constant, They are not creased and they are all conveyed up to their stop-plate.
  • FIGURE is a schematic plan view of a first-in first-out stacking device according to a preferred embodiment of this invention, with parts of its supporting table broken away.
  • the device is shownherein mounted on a top of a table TA along which a carriage Stw may be moved by a chain CH driven by a gear and reversible motor mechanismor transfer device TD.
  • the letters L which enter the carriage Stw are pinched between two belts B 1 and B 2 and first move past five rollers I through V on the carriage before they reach the roller A on the pivotal axis of the mounting for the pivoted stackinghead Stk, at which roller A they approach the end of their pinching between the two belts B 1 and B 2.
  • the belt B 1 may be directly driven by a motor M mounted on the carriage Stw, and it may drive the belt B 2 by frictional contact therewith and the letters L fed between these two belts. These letters L thus completely emerge from the pinching belts B l and B 2 only when their trailing edges have left the roller V.
  • each letter L When the leading edge of each letter L will have arrived approximately at the roller C on the pivoted stacking-head Stk, it is pulled by friction with the stacking belt S over the input end of the stack as far as the stop-plate T mounted on the stacking-head Stk, which plate T is adjacent the stack holding means H which may include a rotating worm like WT described below.
  • the stacking belt S may be driven by a belt SS between the stacking head pivot roller A and roller B to insure that belts B 1, B 2 and S all travel at the same speed, and also to avoid the weight of having a separate drive motor on the stacking head for the belt S.
  • a first-in first-out stacking device for postal type documents comprising:
  • a pair of spaced limit switch means mounted on said carriage and controlled by the position of said stacking means with respect to said carriage means to operate said means for moving said carriage to maintain said carriage means within the spacing of said limit switch means at a predetermined distance from the input end of the stack.
  • said stacking means includes a stop plate (T) at the input end of the stack.
  • a device according to claim 1 wherein said means for moving said carriage means includes a reversible motor means.
  • said stacking means comprises a friction belt for moving the documents, and rollers around which said belt rotates.
  • said stacking means also includes worm means for feeding the trailing portion of a document toward the stack to be out of the way of the next succeeding document fed to said stacking means.
  • said feeding means on said carriage means comprises a pair of pinching belts between which the documents are fed and a plurality of rollers for backing up said belts.
  • said stacking means includes a pivot coaxial with one of said rollers.
  • said pair of limit switch means include a cam means mounted on said stacking means.
