Definitions

  • This invention relates to an apparatus for inserting documents into envelopes and enclosing the same therein.
  • the main object of the invention is to provide an apparatus of this kind in which the insertion of the documents into the envelopes is effected in a more simple and efficient manner. 7
  • the envelopes which are supplied from a stack and the documents to be inserted in the envelopes and which are delivered from a separate stack are transported in horizontal planes in directions at right angles to each other, the open end of the envelopes facing in a, direction at right angles to that of their transportation and the direction of transportation of the documents being towards the said open ends of the envelopes, air being injected into the open end of the envelope in order to blow it open, this injection taking place at a point where the transported, documents reach the line of transportation of the envelopes.
  • Figures 1 and 2 are respectively a plan view and a part sectional elevation showing the essential parts of the machine partly broken away, and Figure 2 also showing the holder for the envelopes,
  • Figures 1a and 2a are respectively a plan view and a part sectional elevation Showing the mechanism for removing sheets of paper from the holder.
  • Figure 3 is a plan view of a part of the appa? of the arrow A, the conveyor belt running over rollers 4 and being kept in tension by an adjustable tension roller 5.
  • c 0 and c are the folding rollers of a document folding mechanism which also comprises folding plates d, (1
  • the folding rollers and folding plates are of a well-' known type and need not be described in detail, they are arranged to receive the documents one by one from the conveyor belt 3 and to deliver 2 Claims.
  • An envelope feeding mechanism is arranged to take the envelopes b one by one by suction from underneath a holder 8 where they are stacked in a pile. This mechanism is described and shown in detail in Patent Specification No. 2,524,417 and is not claimed per se in the present application.
  • the envelopes are fed in the direction of the arrow B transverse to the direction from which the folded documents are delivered by the folding rollers 0 0 so that each envelope arrives on the table 1 in the position indicated in Figure 1 by the broken line b with its open side facing towards the folding mechanism and with its flap b underneath the table 6.
  • a guide 9 is provided for locating the back edge of the envelope and a lay finger I0 is provided for checking the forward movement of the envelope when it arrives in the proper position for receiving a document from the folding mechanism.
  • a suitable cam or the like (not shown) is arranged to lower the finger l 0 out of the path of the envelope after a document has been inserted therein to allow the filled envelope to continue its movement over the table I from which it is fed to a suitable moistening, sealing and packing mechanism (not shown). If a self-sealed rubberised sealing flap is used no moistening mechanism is necessary.
  • Suitable feeding mechanism shown in the draw ing by an endless feed band I I is arranged to feed each. envelope continuously in the direction of the arrow B except when the envelope is temporarily arrested by the action of the lay finger I0.
  • the envelopes may be inserted in the holder 8 with their flaps open; however, they may be stacked therein with their flaps folded over and in that case flap opening means of any suitable known type is arranged to open the flap of each envelope so that the flap passes under the table 6.
  • a compressed air conduit 12 mounted with a number of nozzles 13 which may consist of simple holes and which are arranged to direct jets of air 1 4 into the open side of the envelope 1) so that the latter is blown open as shown in Figure 2.
  • nozzles 13 which may consist of simple holes and which are arranged to direct jets of air 1 4 into the open side of the envelope 1) so that the latter is blown open as shown in Figure 2.
  • feed rollers I5 mounted on a shaft [6 and arranged to feed the folded document over the table 6 into the envelope held open by the action of the air jets M.
  • the feed rollers I5 are so spaced apart as to leave a clear space between the shaft 16 and the table 6 for the passage of the air jets from the nozzles l3 into the envelope 2).
  • the compressed air is supplied to the conduit l2 by a tube 46 which is connected to the outlet of a centrifugal fan 39, belt-driven by an electric motor 26.
  • the suction side of the fan 39 is connected by a flexible conduit 38 to a suction nozzle I9 which applies the suction to the pile, of documents for separating the sheets from the pile and feeding them for insertion into the en.- velopes.
  • Any suitable means may be provided for turning over the envelope flaps so as to close the envelopes as they pass over the table I.
  • Compressed air is supplied continuously to the nozzles 13 and the folding rollers c and a, feed rollers l and feeding mechanism I I are continuously driven by suitable known means (not shown).
  • the operation of the lay finger I0 is so timed that each envelope is arrested in the position shown in Figure 1 and held momentarily in this position to allow a document to be inserted, whereupon it is carried forward by the action of the feed mechanism II so as to make room for the next envelope.
  • the document feeding mechanism to be hereinafter described, and the envelope feeding mechanism above referred to are, synchronized so that each document arrives at the feed rollers l5. at a time when an envelope is momentarily held by the finger l0 in position to receive it.
  • the suction nozzle I9 is carried by a shaft 20 by means of a bracket 21.
  • the shaft extends horizontally above the top of the pile of sheets a adjacent one side thereof and being arranged to slide at its ends in slots provided in a pair of rocking arms 22 fixed to a horizontal rock shaft 23 located underneath the pile of sheets a, the said rocker arms being so arranged that they project upwardly from the rock shaft 23 at 0pposite sides of the, pile.
  • Located adjacent the arms 22 are a pair of vertical reciprocating push rods 24 passing through guide sleeves 25 and attached'to track bars 26 adapted to support the shaft 20 through the intermediary of antifriction rollers 27 mounted on the ends of the shaft 20.
  • the mechanism feeding the sheets is operated by means of an electric motor and through the intermediary of suitable mechanism described in the concurrent Patent Application No. 791,059 whereby the push rods 24 and the rock shaft 23 are actuated, the push rods being moved up and down by a lever 32 movably suspended from the frame by a link 33 and the shaft 23 being rocked by a link 35 actuated in turn by a lever 33, the levers 32 and 33 being part of the suitable mechanism which is operable from the electric motor (not shown).
  • the general arrangement is such that du i g 4 each cycle of operation the push rods are first lowered suificiently to allow the suction nozzle 19 to move downwards to the maximum extent which may be necessary to bring it into engagement with the top of the pile, being then raised so that they lift the nozzle to a fixed level for the delivery of a sheet.
  • the arrangement is further such that there is a dwell at each end of the reciprocating movement of the push rods.
  • the actuating mechanism of the rock shaft is such that during each cycle of operation the rocking arms 22 move in the following manner: At the end of the upward movement of the push rods 24 the rocker arms are inclined forwardly as shown in full lines in Figure 20, so as to deliver a sheet held by the suction nozzle in between the roller 4, and a feeding roller 36 or other means for carrying the sheet away.
  • the arms return to a vertical position during the dwell at the upper end of the reciprocating movement of the push rods 24 and remain in this vertical position during the downward movement of the push rods.
  • Figure 4 shows the removal of the envelopes b from their holders 8 and this figure is taken bodily from Patent No. 2,524,417 and no claim is made thereto per se herein. It should be noted that the present case and the said patent have a common assignee.
  • the envelopes are supported on two ledges 49, 58, while allowing free access to the under surface of the lowermost envelope to a pneumatic suction nozzle 5
  • the means actuating the nozzle include a transverse shaft 52 to which the nozzle 5
  • I! indicates adjusting means provided on the folding plates (1 d for controlling the length of the folds of the paper; they consist of stops displaceable along the plates and set in the position corresponding to the point in the length of the paper where the fold is to be made; l8 indicates a micro-switch which will break an electric contact to stop the driving mechanism if two documents instead of one are taken in between the feed rollers c and 0 thereby preventing two documents from being inserted into one and the same envelope.
  • each envelope passes one by one over the table 1 and each envelope is momentarily arrested by the finger in the position shown with its open flap b under the table 6.
  • the envelope is blown open by the action of the air jets 14 (two such jets being preferably used) as soon as the front edge of the envelope comes against the finger [0.
  • the action of the air jet is continuous but, owing to the rapid movement of the envelope over the table, it is not until the movement of the envelope is arrested by the finger 10 that the air opens the envelopes.
  • the documents pass one by one through the folding mechanism by which they are folded and delivered to the table 6.
  • Each folded document arrives at the table 6 immediately after an envelope has arrived in the position indicated and the feed rollers 15 continue the forward movement of the document and push it into the envelope held open by the action of the air jets.
  • the lay finger I0 then retracts and allows the filled envelope to be moved forward and then closed after which the envelope is sealed by the action of pressure rollers and delivered to a packing device.
  • envelopes having one end flap ungummed may be used.
  • the machine may then operate to close and seal the main or top fiap just as it would for completely sealed packets.
  • the filled envelopes delivered will be open at one end and will thus qualify for the cheap postal rate.
  • the end flap is loose but is of sufficient length to be enclosed under the back of the envelope, thus enabling air to be injected into the said envelope without displacing the ungummed fiap.
  • the sheets are kept in the proper alignment in a known manner by means of guiding wheels 41 supported by a bracket 48 attached to the frame of the apparatus and by a slotted guide bar 41 fitted at right angles to the wheels 41.
  • An apparatus for filling series of envelopes with documents comprising a holder of a. stack diate the tops of the first two tables, means capable of conveying the envelopes along the said first table, means capable of transporting the documents along the said second table at right angles to the direction of transportation of the envelopes, means for injecting air into the envelopes disposed at a point between the two tables in order to blow the envelope open, means at this point for introducing the documents into the envelopes and the means for introducing the documents into the envelopes consisting of feeding rollers disposed above the third table and a shaft carrying the said feeding rollers, the means for injecting the air lying between the delivery end of the second table and the document feeding rollers, and the latter being spaced apart in order to allow the air to be blown into the envelopes from the said air injecting means between the said shaft and the third table.
  • An apparatus for filling series of envelopes with documents comprising a holder of a stack of envelopes, a holder of a stack of documents, a table along which the envelopes can be transported singly from their holder, a table along which the documents can be transported singly from their holder, means capable of conveying the envelopes along the said first table, means capable of transporting the documents along the said second table at right angles to the direction of transportation of the envelopes, means for injecting air into the envelopes disposed at a point between the two tables in order to blow the envelope open and means at this point for introducing the documents into the envelopes, the apparatus further comprising a suction nozzle arranged over the stack of documents for removing them one after the other and delivering them on to the table along which they are transported, a centrifugal fan, an electric motor driving the centrifugal fan, a pipe connection from the outlet of the centrifugal fan to the said air injecting means and a pipe connection between the suction side of the said centrifugal fan and the said suction
