Definitions

  • This invention relates to apparatus for collating sheets, such as may be incorporated in an inserter for inserting sheets into envelopes.
  • Inserter systems are used by organizations such as banks, insurance companies and utility companies for producing a large volume of specific mailings where the contents of each mail item are directed to a particular addressee. Additionally, other organizations, such as direct mailers, use inserts for producing a large volume of generic mailings where the contents of each mail item are substantially identical for each addressee. Examples of such high volume inserter systems are the .8,9 and 14 series inserter systems available from Pitney Bowes, Inc., Stamford, Connecticut.
  • inserter systems are not limited to such high volume applications as they also have considerable utility in lower volume applications, such as SOHO (small office/home office) applications.
  • SOHO small office/home office
  • An example of such a SOHO inserter system is the tabletop 3 Series inserter system available from Pitney Bowes Limited, Harlow, England. This inserter system has been designed for implementation on a table top surface while providing many automated features and requiring little maintenance. In other words, it has been designed to be operated by an ordinary office worker with little or no training in operating inserter systems. Therefore, regarding the operation of such inserters, it is critical that they provide many automated and self adjusting features while having a high degree of reliability.
  • Inserters are well known having sheet feeding stations for feeding for example individually typewritten or printed sheets, an optional insert feeder for feeding standard inserts (e.g. advertising material, printed information that is uniform for all addressees etc.), a folding station for folding sheets fed from the sheet feeders and receiving one or more inserts into a fold produced by the folding station, an envelope feeding station, an insertion station to which the envelope is fed, with its flap in an open position, an envelope opening device at the insertion station for separating the front and rear panels of the envelope, a feed path for feeding the folded sheets, and any inserts, into the waiting open mouthed envelope at the insertion station, an optional moistener for receiving the filled envelopes from the insertion station and for moistening the (gummed) envelope flap, an envelope sealing device for sealing the envelope and an outlet through which the filled and sealed envelope is delivered for the application of postage and for subsequent mailing.
  • standard inserts e.g. advertising material, printed information that is uniform for all addressees etc.
  • a folding station for folding sheets fed from the
  • the inserter is a tabletop inserter and generally consists of an upper housing mounted atop a lower housing.
  • Upper housing generally includes first and second sheet feeders and, preferably an insert feeder. Individual sheets are preferably conveyed from each sheet feeder and into respectively first and second feed paths. The first and second sheet paths merge with one another at a collation station having first and second collating rollers.
  • the collating station is operative to align the leading edges of first and second sheets being respectively conveyed from the first and second sheet feeders, via the first and second sheet paths, within the nip formed between the collating rollers. Once aligned, the collating rollers are actuated to simultaneously feed the aligned sheets in a supply path downstream of the collating station. These aligned sheets are also known as a "collation". This sheet collation as prepared by the sheet collation apparatus described above is then conveyed downstream in the supply path to the folding station. After this, the folded collation is inserted into an open envelope and the envelope flap moistened and sealed, these steps being performed automatically by the inserter as described in the opening passage of this specification.
  • each sheet feeder When using the inserter described, each sheet feeder is loaded with sheets of a different kind. Therefore, when preparing a collation of two sheets which can be regarded as sheet 1 followed by sheet 2, one tray is loaded exclusively with sheets 1 while the other tray is loaded exclusively with sheets 2. Since sheets 1 and 2 can be fed simultaneously to the nip of the collating rollers at the collation station, each collation can be assembled relatively rapidly. However, the operator has to load each tray manually with a batch of identical sheets of the appropriate kind, which is different for the different trays.
  • apparatus for collating sheets comprising:
  • the sheet(s) received by the accumulation station for return to the collation station originated from the feeding means, which also supplies the next sheet to the collation station, it is necessary for the operator to manually prepare only one stack of sheets for the sheet feeding means (when taking the form of a sheet feeding tray or the like), the stack consisting of successive alternate sheet numbers, i.e. sheet 1, sheet 2, sheet 1, sheet 2 etc.
  • a printer used for printing the sheets only needs to be set once for printing such sheets and can be left at the same setting for printing all subsequent batches of sheets for the sheet feeder.
  • the operator has to separately instruct the printing of two batches of differently number sheets, and to reinstruct the printer twice for the printing of each subsequent batch.
  • the sheet feeding means to comprise an automatic sheet feeder connected to supply sheets printed by a printer, directly to the collation station. Then, there would be no need for operator intervention at all.
  • the collation apparatus may be used for forming a collation of two, three or any other higher predetermined number of sheets.
  • the known collator according to our above-mentioned European patent application EP-A-0 700 794 and EP-A-0 943 459 can only form a collation of two sheets since it has only two sheet feeders. Whilst in principle further sheet feeders could be incorporated in the collator where a collation of three or more sheets is required, this would undesirably add to the constructional complexity, geometrical dimensions and cost.
  • the collation station is provided with a pair of collation rollers defining a nip and power means operable for rotatably driving the rollers, the nip of the rollers, when the latter are not driven, serving for effecting the collation of sheets at the collation station when driven into the nip and the rollers being drivable in association with second driving means of the accumulation station for selectively effecting the transfer of sheet(s) to the accumulation station and the driving of said collation from the collation station along the exit path, the second driving means being reversible for effecting the return of the sheet(s) at the accumulation station to the collation station.
  • Such multi-tasking of the collation rollers contributes to constructional simplicity.
  • the first and second paths merge ahead of the nip of the collation rollers
  • the collation station includes a diverter movable between a first position for permitting the feeding of each sheet along the first path to the collation station and a second position for diverting the sheet(s) along the second path during the transfer thereof from the collation station to the accumulation station.
  • the diverter functions as a simple and effective means for effecting the required routing of the sheet(s) from the collation station to the accumulation station.
  • apparatus for collating sheets comprising:
  • Such apparatus affords all the advantages offered by the collation apparatus according to the first aspect, while also displaying constructional simplicity through the multi-tracking operation of the rollers and the use of the diverter, which can take the form of a pivotably mounted guide.
  • a particularly compact arrangement results from a sheet collating apparatus in which the feeding means comprises a generally horizontally arranged tray for a stack of sheets, and a feeder for feeding one sheet at a time from the tray to the collation station, and wherein said tray is arranged in a lower region within a main housing of the apparatus, the accumulation station being located above the tray.
  • This arrangement for the tray and accumulation station also lends itself readily to be designed so as to be accessible from the front of the apparatus, which is convenient for the operator, while not occupying space that would normally be required for the operator interface/operating panel, (i.e. at a raised position on the front and/or top of the main housing).
  • the accumulation station is arranged also to serve as a daily mail feeder, so that a selected insert sheet or groups of sheets may be manually inserted into the accumulation feeder, after the collation of the predetermined number of sheets has been formed.
  • the accumulation station is then arranged to feed the inserted daily mail to the collation station, after which the collation, together with the collated daily mail, is driven from the collation station along the third path.
  • the apparatus for collating sheets may further comprise an auxiliary sheet feeding path for connection to a sheet printing apparatus or a supplementary sheet feeding tray for use in delivering printed sheets supplied one at a time from the printing apparatus or supplementary sheet feeding tray, to the collation station.
  • the driving means of the accumulation station prefferably comprise a pair of rollers defining a nip. In this way, it is possible to handle daily mail in the form of a stapled collation of sheets.
  • the first and second paths are so arranged as to reorientate each sheet when supplied to the collation station along either path from the tray and the accumulation station respectively, from a generally horizontal disposition to an upwardly orientated disposition, and wherein said third path has a generally upward disposition.
  • Such an arrangement avoids a layout for the internal components of an inserter, in which the front-to-rear external dimensions of the inserter are undesirably large.
  • this arrangement effectively dictates that any folding arrangement (of an inserter including the collation apparatus that is required to feed the assembled collation be positioned in an upper region of the inserter, which is desirable for reasons of layout and jam clearance of the folding arrangement.
  • the apparatus for collating sheets may be further provided with a folding arrangement comprising a first folder located in an upper region of said main housing for effecting a first fold following each sheet collation being delivered to the first folder along said third path and a second folder located in a rear region of said main housing to one side of said third path for effecting a second fold on each sheet collation, the second folder having an exit path for the folded collation that crosses said third path from the one side of that path to the opposite side.
  • Such a layout for the two folders reduces the "footprint" of the folding arrangement, while placing the two folders where they can readily be cleared of sheet jams without occupying space at the front of the inserter, which is needed for other functionality, i.e. the user/inserter interface.
  • a preferred form of apparatus further comprises a reader of a code on a control sheet when being fed to the collation station, said code denoting said predetermined number of sheet to form a collation, and control means responsive to the code determined by the reader to repeat the collation of sheet(s) from the accumulation station and the next successive sheet from the sheet feeding means, until said predetermined number of sheets is reached.
  • the apparatus for collating sheets may be provided with a further feeding means for feeding a respective sheet along a respective path to the collation station, for collation with the sheet collection formed from the sheets fed from the first mentioned feeding means.
  • a method of collating sheets comprising:
  • the method for collating sheets may employ a first feeding means for feeding the plurality of sheets to the collation station, and may further comprise the step of feeding a respective sheet from a second feeding means and along a respective path to the collation sheet, and collating the respective sheet with the sheet collation formed from the sheets fed from the first feeding means.
  • FIG 11 shows an overall perspective view of a folder-inserter 100, as seen from the front and to one side, the folder-inserter being used for preparing a mailpiece.
  • the folder-inserter comprises a main housing structure 2, at the front of which and at the bottom is located a sheet feeder 3 including a first sheet feeding tray 4 (feeding means). Above the sheet feeder 3 is an accumulation station 8 which is located under an output station 90 including an output tray 91.
  • an envelope feeder 26 and, rearwardly thereof, an insert station 28 for feeding an optional insert sheet for the mailpiece to be prepared.
  • a display and control unit 95 which provides an operator interface, by means of which an operator is able to control and use the folder-inserter from its front side.
  • FIG 1 there are shown internal structural components of the tabletop folder-inserter 100, which includes a sheet collation apparatus 1 of a preferred form. It is to be understood that the tabletop folder-inserter 100 is not to be regarded as the only environment for use for the sheet collation apparatus of this form. Indeed, other environments involving sheet handling are envisaged, including in particular other forms of inserter or any other mechanism requiring a collation apparatus for collating sheets of paper. For this reason, the description to be given below of the inserter 100 is only of a general character.
  • housing structure is of no particular importance, though it will normally be designed so that one or more sections can be opened by pivoting, removal or the like for access to the internal components of the inserter for maintenance and jam clearances.
  • the sheet collation apparatus 1 includes the sheet feeder 3 provided in the lower section of the housing structure, the first sheet feeding tray 4 projecting forwardly from a front face of the inserter to enable an operator to periodically recharge the tray with fresh sheets, a separator wheel 5 and a pivotally mounted, cam operated, rocker arm 6 below the separator wheel 5, so that when pivoted into its raised position, it will urge the stack of sheets in the first sheet feeding tray 4 into engagement with the rotating separator wheel, which accordingly drives the uppermost sheet along a sheet feeding path 7.
  • Sheet accumulation station 8 Positioned above the first sheet feeding tray 4 is the sheet accumulation station 8 of the collation apparatus 1, for accumulating one or more sheets initially supplied from the first sheet feeding tray 4.
  • a sheet diverter or deflector 11 is pivotally mounted on pin 112 beneath the sheet collation station 10 and defines a lower guiding surface of the second, sheet transfer, path 9, the deflector being biased in a direction (anti-clockwise in Figure 1) so as normally to be located blocking the first path.
  • Sheet accumulation station 8 is preferably also designed as a "daily mail" tray into which so-called daily mail may be manually inserted for folding and inserting into a respective envelope. This daily mail may be a single sheet, or a number of sheets, which may or may not be stapled together, or some of which may be stapled together.
  • Sheets are successively fed one at a time from the sheet feeding tray 4 along the sheet feeding path 7.
  • the deflector 11 As the leading edge of each advancing sheet strikes the deflector 11, the latter is caused to pivot against its spring bias, thereby allowing the sheet to advance beyond the deflector to the collation station 10, at which the leading edge of the sheet is arrested in the nip defined between a pair of collation rollers 12 at the collation station, which are non-driven when the sheet is advanced into the roller nip but which are selectively drivable, in a manner to be described below.
  • the leading edges of the plural sheets become aligned.
  • the collation rollers are driven simultaneously to advance the sheet collation along a third, sheet feeding, path 13 to a folding station 14.
  • An auxiliary sheet feeding path 33 extending upwardly from the underside of the inserter 100 and merging with the sheet feeding path 7, serves for connection to a separate sheet printing appliance, e.g. laser jet or ink jet printer disposed below the inserter, or a supplementary sheet feeding tray, for use in delivering printed sheets one at a time to the collation station for inclusion in each sheet collation formed at the collation station.
  • This path 33 provides an alternative supply of printed sheets to that provided by the sheet feeder 4.
  • the folding station 14 serves to form two folds in the collation fed along the third path 13 from the collation station 10.
  • first sheet folder 15 located in an upper region of the housing structure 2 for effecting a first fold on the sheet collation and a second sheet folder 16 located in a rear region of the housing structure rearwardly of the path 13, the second sheet folder serving to fold the once-folded collation a second time.
  • a drive roller 17 of the sheet folder is in permanent driving contact with driven rollers 18-20.
  • the first sheet folder includes a roller pair 22 which, as the advancing sheet enters the roller nip (which event may be detected optically or in any other suitable way such as will be known to the skilled person) applies drive to the roller pair over a predetermined angular rotation and then stops, to determine the predetermined stop position of the leading edge of the sheet collation.
  • This "intelligent" nip provides a preferred way of determining the predetermined stop position of the collation leading edge, or in other words the location of the first fold to be made to the sheet collation.
  • Other ways of achieving such arrestation of the collation will be apparent to the skilled person, such as a stop member provided with means for setting the position of that stop member as required.
  • This folder includes a manufacturer adjustable stop 23 (for the US or European market) which arrests the leading edge of the folded collation while the roller pair 17, 19 continues to drive the trailing section of the collation to cause the section between that roller pair and the folding station 14 to buckle forwardly and downwardly into the nip of the roller pair 17, 20, to form a second fold in the collation (Figure 2d).
  • the position of the stop 23 determines the position of the second fold.
  • This roller pair 17,20 advances the double-folded sheet collation across the feed path 13 and into the nip of a further drive, driven roller pair 24, which advances the double-folded sheet collation along a further path 25 ( Figure 2e) to a stuffing station 27 ( Figure 1), to which an envelope from the envelope feeder 26 has been advanced.
  • the arrangement produces a C-fold as schematically indicated in Figure 2e.
  • the envelope is thereby forwarded by a traction belt 41 along a path 42 to a roller pair 43 by which the envelope's flap is engaged with a flapper blade 44 so that the envelope is held rear face down and envelope flap open and trailing.
  • the double-folded sheet collation is then driven into the waiting envelope until its leading folded edge engages the crease along the bottom edge of the envelope.
  • an insert sheet can be advanced from insert station 28, when the second fold in the collation is formed by the nip between roller pair 17, 20, which is then fed along the feed path 25 into the open envelope at stuffing station 27.
  • the stuffed envelope is driven successively to a moistener 29, which moistens the flap of the envelope, and to a sealing station 30.
  • the sealing station 30 includes an inducer 50 which is moved towards a sealing roller pair 31, which is also part of the sealing station 30 and which closes and seals the moistened flap against the rear panel of the envelope and ejects the thus-prepared mailpiece from the front of the folder-inserter 100.
  • Figure 3a shows the top two sheets A 1 , A 2 of a stack of sheets held in the sheet feeding tray 4.
  • a second sheet feeding tray indicated schematically at 34 may be disposed beneath the first sheet feeding tray as illustrated schematically in Figure 3a, either integrally with the rest of the folder-inserter as illustrated in Figure 11a, or as a "bolt-on" unit to that of Figure 11.
  • the construction and basic operation of tray 34 may be equivalent to that of tray 4, with a respective feed path 35 leading to the collation station.

  • the procedure for moistening the flap of an envelope within the folder-inserter 100 will now be described.
  • the folded collation sheets are inserted into the envelope within feedpath 25 at the stuffing station 27.
  • the envelope is then transported by a driven roller 31a of roller pair 31, which is cooperating with a not shown driven roller mounted on the end of pivotable support arm 80, to pass the envelope over the moistener tank 70.

  • a deflector 85 is arranged above the moistener tank 70, in particular above the openings 79 of the cover 78 in which the wicks 71 are accommodated to bring the flap of the envelope into contact with the wicks 71 when required to moisten adhesive therein.
  • the deflector 85 pivots about a pivot point 82 and is moved downwards only at that time. Transport of an envelope etc. through this zone is assisted by a drive roller 88. A plurality of laterally-spaced lightly-sprung fingers 89 over which the envelope is transported serve to keep the envelope flap away from the wick and prevent it being moistened, except when the deflector is actuated. If an envelope is not moistened it will merely be closed rather than sealed at the subsequent sealing station.
  • the deflector is solenoid-operated by the crease datum position detector (sensor) described hereinafter. By pivoting the deflector about its pivot point 82, it is moved downwards so that the flap is brought into contact along the wicks 71 for depositing liquid thereonto. Additionally, spring biased perforated elements can be arranged between the envelope and the wicks which are pressed down by the movement of the deflector 85 so that the wicks 71 are protected from excessive wear due to unnecessary contact of the wicks with the envelope.
  • Figure 12a it is shown that a body 62 of the envelope is transported by a first roller pair 131 in a direction leading the envelope to the vicinity of a sealing roller pair 132 as shown by the corresponding arrows.
  • a buckle roller pair 133 is arranged downstream from the first roller pair 131 and the sealing roller pair 132, with an engageable roller 133b of the buckle roller pair 133 spaced apart from a fixed roller 133a of the buckle roller pair 133.

  • Figure 12d shows that the buckle roller pair 133 transports the envelope in a direction substantially opposite to the direction of the transporting roller pair 131 which is engaged with the flap 61 of the envelope.
  • the crease line 63 of the envelope is inserted into the nip of sealing roller pair 132.
  • the envelope is closed by pressing the flap 61 and the body 62 from opposite sides by sealing roller pair 132 as shown in Figure 12e.
  • the buckle roller pair 133 can be replaced by a clamp (not shown) which holds the body 62 of the envelope by engaging clamp parts with the envelope from opposite sides while it is moved along in the transport direction, so that the envelope buckles.
  • the crease line is inserted into the nip of the sealing roller pair 132 by transporting the envelope by means of transport roller pair 131. Thereafter, when the crease line is engaged with the sealing roller pair 132, the clamp will be released from the body of the envelope so that the flap can be sealed to the body of the envelope as shown in Figures 12e and 12f.
  • the buckle roller pair can alternatively be driven significantly slower than the transport roller pair 131, whereby to insert the crease line into the nip of the sealing roller pair 132.
  • the flap of the envelope can be first transported through the transport roller pair 131, that is the envelope can be moved with the flap leading, rather than the body leading.
  • each roller of the sealing roller pair 132 can respectively serve as a roller of the transport roller pair 131 and the buckle roller pair 133, so that a minimum of four rollers is required for sealing the envelope, as will now be described.
  • Figure 10 shows the inducer 50 in a lowered, second position in which the inducer is not engaged with the envelope.
  • the flap of the envelope on which liquid has been deposited from the moistener tank 70 has now to be closed and sealed to the body of the envelope.
  • the roller 31a and a roller (not shown) at the end of the support arm 80 comprise first transport means which transport the envelope with the flap facing downwards at the trailing end of the envelope to the sealing station 30.
  • the sealing station 30 comprises the inducer 50 and the sealing roller pair 31, including the drive roller 31a by which the envelope is transported to the sealing station 30.
  • the inducer 50 of the sealing station 30, which can be formed as a one-piece component, has a curved transverse elongate guide portion 51 at one end of which and on one side of which a transverse protrusion 52 is located.
  • the inducer 50 On the other side of the portion 51 to the protrusion 52, the inducer 50 has a transverse rectangular portion 57 which extends away from the protrusion 52 and is substantially at a right angle at the protrusion 52, as viewed in side elevation.
  • a roller 53 At the part of the rectangular portion 57 extending away from the protrusion 52, there is mounted a roller 53 which in a raised, first position of the inducer 50 is engaged with sealing roller 31b, as illustrated in Figure 7 (engaged position).
  • the inducer 50 is illustrated in the lowered, second position, in which the roller 53 is not engaged with the sealing roller 31b.
  • Roller 53 and drive roller 31b comprise a second transport means (envelope buckling means) and rollers 31a and 31b comprise sealing means.
  • Figure 12g illustrates a four roller arrangement, using the reference numerals of Figures 7 and 10, in a schematic manner and analogous to Figures 12c to 12d, rather than the six roller arrangement shown therein.
  • the roller which is not visible in Figures 7 and 10 is indicated as roller 83 in Figure 12g.
  • the inducer 50 After liquid has been added to the flap of the envelope from the moistener tank 70, the envelope with the envelope body leading is transferred to the sealing station 30. At that time the inducer 50 is in its lowered, second position (idle position) as shown in Figure 10.
  • the drive roller 31a and the roller (not shown) at the end of the support arm 80 transport the leading edge of the envelope body beyond the sealing roller pair 31 until the crease line of the envelope, which is the line that is formed between the flap and the body of the envelope, is located before or substantially over the protrusion 52 of the inducer 50.
  • the inducer is actuated by pivoting upwards around a fixed rotation axis 54 so that the crease line of the envelope is forced (pushed) towards and into the sealing nip of the sealing roller pair 31.
  • the protrusion 52 thus supports the crease line, which is to be inserted into the nip of roller pair 31.
  • drive roller 31a which rotates in Figures 7 and 10 in counter-clockwise direction, engages with sealing roller 31b, so that sealing roller 31b rotates in Figures 7 and 10 in clockwise direction. Due to these rotation directions of sealing roller pair 31, the body of the envelope, which is urged upwards by the rotation of the sealing roller 31b and the roller 53 carried by the inducer 50, and the flap, which is urged upwards by the drive roller 31a and the roller (not shown) at the end of support arm 80 in a somewhat opposite direction to the envelope body, if the flap is still driven thereby, form a buckle.
  • the tip of which is at the crease line of the envelope, which buckles upwards and thus forms the first part of the envelope that is inserted into the nip of sealing roller pair 31.
  • the buckling at the crease line upwards is supported by curved portion 51 of the inducer 50 and the protrusion 52.
  • the envelope is moved further upwards by the sealing roller pair 31 so that the flap is closed and sealed against the body of the envelope.
  • the closed envelope is directed upwards by the roller pair 31 to an ejection roller 87 and the envelope pivots roughly the order of a right angle around a turning axis 86 as it exits the interior of the folder inserter 100, so that it falls downwards onto the output station 90, landing with the envelope flat on the output tray 91.
  • the inducer 50 further acts as a diverter if only folded sheets are to be ejected out of the tabletop inserter and no envelope is required.
  • the curved portion 51 corresponds substantially with the curvature of the drive roller 31a, and the protrusion 52 is substantially arranged underneath the nip of roller pair 31.
  • the envelope starting with its leading edge begins to exit the folder inserter 100 at a casing opening 55 of housing structure 2, when the inducer 50 is in its lowered, second position. Subsequently, the crease line of the envelope is brought into contact with the sealing roller pair 31 by raising the inducer 50, and sealed, as described above, and the envelope directed upwards to turning point 86 and ejected out of:the housing structure 2.
  • the ejected envelopes are stored at output station 90.
  • the closed envelopes exit the housing structure 2 of the folder inserter at an opening which is not specifically indicated in Figure 11.
  • the opening for ejecting the closed envelopes is underneath the plurality of ejection rollers 87 which are shown in Figure 11.
  • the selective driving of the various rollers, in one or the other direction, or both, as well as the timing of the various operations is effected by a controller (not shown), which may for example be run under micro processor control.
  • the envelope is appropriately positioned for the flapping, insertion, moistening and sealing operations, and in the case of moistening, that the deflector 85 is moved when the envelope flap is in the appropriate position, and in the case of the sealing operation that the inducer 50 is brought into its raised position at the appropriate time.
  • a sensor 93 which employs a photosensor 99, a light source (not shown) and means 94 for interrupting the optical path therebetween, in order to detect an envelope in the envelope feed path 42.
  • the envelope feeder (26 in Figure 1) has traction belt 41.
  • Roller pair 43 serves to drive a fed envelope towards the insertion area 27 (stuffing station in Figure 1), back around the path 98 to the flapper blade 44 and flapping chamber 47, and subsequently into the insertion area, as described above.
  • the roller pair 43 is driven by a stepper motor (not shown).
  • a pivotably mounted diverter 96 When an envelope 60 is fed by belt 41 along the envelope feed path and towards the insertion area (step 102 of Figure 14), a pivotably mounted diverter 96 first detects its leading edge (step 103) and then detects its trailing edge (step 104), which for an unflapped envelope corresponds to the crease line. This is as a result of a flag 94 moving between the light source and the photosensor, since it moves with the diverter, and serving to interrupt or open the optical path therebetween, depending on the relative position of the flag and the sensor.
  • the stepper motor is stopped when the trailing edge is detected (optical path interrupted again) and the position the trailing edge (crease line) adopts is set as a datum position (datum point or predetermined reference position) for the trailing edge (crease line) (step 105).
  • the length of the path between the datum position of the trailing edge (crease line) and the flapper blade 44 is a fixed distance (predetermined distance) and is the same for all envelope lengths.
  • the stepper motor will have to be driven (in the reverse direction) a fixed number of steps to position the trailing edge (crease line) of the envelope appropriately for the flapper blade, that is a predetermined reverse drive flapper count.
  • the length of the path between the flapper blade 44 and the insertion area 27 is also a fixed distance and similarly means that the stepper motor will have to be driven (in the original direction) a respective fixed number of steps (a respective count) to the insertion area.
  • the distance the crease line of an envelope will have to be moved from the insertion area 27 to the sealing station 30 will be the same for all lengths of envelopes, and hence a respective stepper motor providing that movement will be stepped a respective fixed number of times, irrespective of the length of the envelope. Since the respective number of steps necessary to move the envelope to each area or station is fixed, correct coordination of the movement of other members at those areas or stations, such as the deflector 85 and the inducer 50 is facilitated. As indicated at step 106 of Figure 14, embedded software can be provided to perform the steps to drive the step motor(s) for the predetermined fixed numbers of counts, and in the appropriate drive directions.
  • the steps for a practical envelope movement process will include additional steps such as checking the envelope feed and sensor operation for errors, incorporating delays between the driving steps, and setting flags to indicate completed stages, thereby permitting related events to proceed.
  • Figures 15a and 15b which together comprise a single flow chart, a specific embodiment of a program for envelope feeding, flapping and preparing for insertion will now be described.
  • the reference numerals used in Figure 13 for the envelope feeder (41), the sensor (93) and the roller drive (43) have also been used in Figures 15a and 15b.
  • the routine starts with driving the feeder 41 and the roller pair 43 (step 150).
  • a query is made 151 regarding whether or not the sensor has been made, namely has the sensor detected the presence of an envelope, if not a sequence 154-158 determines if the envelope has been driven for long enough, if there is an error or attempts a restart of feeder 41. If the sensor has detected an envelope a flag is set 152 which can be used for other purposes, and the feeder 41 driven 153 for the appropriate time so that the sensor can detect the trailing edge of the envelope, namely the crease line, at 159. Failure to detect at this stage can result in an error message and includes checking that the envelope was driven for long enough 160.
  • roller drive 43 is driven for a predetermined time corresponding to a clearance count 161, is stopped 162, reversed 163, the reverse state indicated, and the envelope driven in the reverse direction (up the flapper path) for a predetermined time 164 and after a short delay 165, driven forward 166 a predetermined time so that the envelope is flapped and driven to the insertion point in one step.
  • a flag is set 167 to indicate the envelope has been flapped and this flag can be used for other purposes i.e. to start other processes.
  • a query is raised at 168 regarding the completion of the insertion counts and roller pair 43 is stopped 196, an envelope complete flag set 170, which indicates that the envelope is in the stuffing (inserting) position, fingers for throating the envelope are driven 171, and the drive for roller pair 43 reversed for a predetermined time to pull the envelope back onto the fingers 172.
  • all distances to be traversed are measured from a datum point corresponding to the position of the trailing edge (crease line) of the envelope at a particular point in the process and thus are independent of the length of the envelope.
  • the same amount of movement, provided by a roller or other drive means, will be needed to move an envelope of any length of envelope between one particular operation area and the next.
  • the process involves stopping the envelope when its trailing edge is detected and the datum point set, stopping is not necessary and the sensor position can be defined as the datum position and the distance to the next operation station measured from it.
  • collation rollers represent one particular preferred way of aligning the sheets of the collation.
  • other ways of achieving this result are also contemplated, such as movable stops.
  • collation apparatus is of simple construction, requires minimal operator effort to reload the sheet feeder and is able to assemble any number of sheets to form each collation, without needing a corresponding number of sheet feeders.
  • the layout of the principal internal components of the inserter results in an extremely compact and ergonomic arrangement, especially due to the design of the collation apparatus with only a single feeding tray, the space-saving design of the folding station with its crossing sheet paths, and the way in which the feed and transfer paths from the sheet feeder and accumulation station, respectively, reorientate the sheets from approximately horizontal to substantially vertical, which largely determines or at least restricts the positions of the first and second folders and feed tray to be desirably configured from an accessibility standpoint whilst maintaining a compact layout.
  • the described sheet folding apparatus is of simple, and compact construction, locates its folders in convenient positions for access, employs generally straight paths for the passage of the sheet collation and relies on the folding rollers of the sheet folders to achieve the required re-orientations of the collation. Positioning the sheet folders in upper and rear sections of the inserter housing avoids the need to provide access to them from the front of the inserter, where the control panel and operator interface are necessarily provided.
  • the described sheet folding apparatus serves to double-fold (C-fold) a sheet collation comprising a plurality of sheets, it will be appreciated that it could be used instead to double-fold a single sheet.
  • the design of the moistener involves a one piece moistener tank, which is a low-cost component, which readily allows the user to see when liquid needs to be added due to the window, which is easily removable for cleaning purposes, for replacement of the wicks or the whole tank structure, and which is easily partially removed for the addition of liquid.
  • the apparatus for sealing envelopes is low cost and able to accommodate envelopes of various sizes, since it is the position of the creaseline which determines (controls) the operation. Excessively long envelopes do not require the apparatus to be extended in length, rather they can emerge through the opening 55 temporarily prior to the actual sealing, if fed with the body at the leading edge.
  • the use of one roller from each of the two transport means to form the sealing roller pair also reduces the cost and the space required in comparison with use of a separate sealing pair.
