Definitions

  • the present invention relates to the technical field concerning introducing inserts into envelopes by automated apparatuses.
  • Enveloping machines are divided substantially in two categories: the first one forms the envelopes from sheet material, while the other uses ready made envelopes.
  • the proposed invention relates to an enveloping machine belonging to the second category.
  • Document US 5.992.132 describes an insertion station with rotating envelope insertion horn for opening an envelope prior to insertion of documents into envelope.
  • the insertion station includes envelope flap retainers and insertion horns each having an underside that assists in helping an envelope conform to the transport belt while not presenting any catch points for the leading edge of the enclosure collation to be inserted in a waiting open envelope.
  • the bottom portion of the stripper blade of each insertion horn serves as a guiding surface when an envelope is being transferred from the transport path onto the transport belt of insertion station.
  • Document US 5.660.030 describes an high speed envelope inserting station.
  • the inserting station includes an envelope feeder and an envelope stuffing apparatus.
  • the enveloping stuffing apparatus comprises conventional framework for supporting various components of the apparatus including a deck support.
  • Envelopes are fed from the envelope feeder to an envelope deck with the rear facing turned upwards.
  • Envelope deck comprises two adjustable side guides each with a bottom member acting as the deck.
  • the object of the present invention is to propose an enveloping machine which is highly reliable and operationally flexible, obtained by means which are constructively simple and which require reduced maintenance operations.
  • Another object of the present invention is to propose an enveloping machine, which provides the above mentioned features and whose performance is higher than the one of known enveloping machines.
  • a further object of the present invention is to propose an enveloping machine which not only satisfies the previously mentioned requirements, but requires also a reduced room with respect to known machines.
  • the reference letter M indicates the proposed enveloping machine, which automatically introduces a set 1 of various inserts and/or sheets into a respective envelope 10, which has a closing flap 11.
  • the machine M is operated in continuous way by motor means, which have not been shown, like other mechanisms operating some of the described means, as they are of known type.
  • the initial section of the machine includes a series of feeding means, also known as sheet feeders, arranged in a line over a sliding surface 2, from which pushing means 3 protrude.
  • the pushing means 3 e.g. lugs, are arranged stepwise in a conveying line 30 (endless) under the surface 2, and are operated in the direction K of Figure 1.
  • the pushing means 3 protrude from corresponding longitudinal slots 32 made along the sliding surface 2.
  • Each sheet feeder drops a single sheet, or insert, on the sliding surface 2, situated below, in step relation with the passage of the above mentioned pushing ludg 3.
  • the conveying line 30 conveys the set 1 of sheets to an enveloping station A.
  • An envelopes feeder 4 of known type, is fixed at the inlet of the station A, over the sliding surface 2 and includes a pair of small belts, whose relative runs 40a, 40b face each other.
  • the envelopes 10 go out from the runs 40a, 40b and are placed in a filling location P in the enveloping station.
  • the set 1 of sheets is moved forward on the sliding surface 2 and goes in abutment against elastic means 42, which are situated under the envelopes feeder 4 and which keep the set 1 of sheets pressed to the sliding surface 2.
  • the envelopes 10 are oriented with their rear face 10a turned upwards and their mouth and the respective flap 11 turned backwards with respect to the feeder ejection direction, which is in agreement with the forward direction K of the conveying line 30.
  • the envelope 10, ejected from the envelopes feeder 4, is thrown toward the filling location P defined by: the sliding surface 2; an upper guiding surface 5; stopping means 6 and means 7 for opening the envelope 10.
  • the upper guiding surface 5 is fixed above the sliding surface 2, at a distance "h” from the latter, so as to delimit an interspace “T", inside which the envelope 10 runs.
  • the distance "h” and the longitudinal position of the upper guiding surface 5 change in relation to the size of the envelope 10 and to the height of the set 1 of sheets.
  • the upper guiding surface 5 is formed by two portions: a first portion 5a, situated near the envelopes feeder 4 and inclined with respect to the sliding surface 2 to define a guiding slope for the envelopes, and a second portion 5b, parallel to the sliding surface 2.
  • the portion 5b of the upper guiding surface 5 features longitudinal slots 50 e.g. two, whose function will be explained later.
  • the stopping means 6 include, as shown schematically in Figure 3: a longitudinal guide 60, fastened to the upper part the upper guiding surface 5; a fastening and longitudinal adjustment body 61, fixed removably to the longitudinal guide 60 and placed longitudinally in relation to the size of the envelope 10; a transverse bar 62 featuring brushes 63, which are situated symmetrically with respect thereto and which, in this particular case, are situated at the ends of the bar and in the longitudinal slots 50.
  • the stopping means 6 include a longitudinal guide 60, a fastening and longitudinal adjustment body 61, a transverse bar 62, and removable stops 66, whose function will be explained later.
  • the bar 62 carries, hinged to its ends, two arms 64 equipped with relative counterbalances 65.
  • the opening means 7 are situated under the sliding surface 2, in the area of apertures 300, seen in Figure 3, made in the above surface.
  • the opening means 7, e.g. tubular elements 80 feature: holes 80a having vertical axis and made perpendicular to the closing flap 11 of the envelope and being fed with a jet of air H, and holes 80b having inclined axis, made crosswise with respect to the positioning of the envelope 10 mouth and being fed with a jet of air K
  • the counterweight 280 is in abutment against a forward belt 29, which cooperates therewith to send the group C, obtained by the introduction of the set 1 of sheets into the envelope 10, to subsequent working stations.
  • the envelope 10 is ejected from the feeder 4, in advance and in time relation with respect to the forward movement of the set 1 of sheets.
  • the tail part 100 of the envelope 10 rubs against the upper guiding surface 5, in particular by its first portion 5a, which guides the envelope into the running interspace T, so that the front surface 10b of the envelope touches the sliding surface 2, and consequently, the tail part 100 is intercepted by the stopping means 6, which keep the envelope in the above mentioned filling location P.
  • step relation the opening means 7 are actuated, i.e. the holes 80a, 80b are fed with respective jets of air H, K.
  • the jet of air H going out of the holes 80a hits the flap 11 and keep it raised above the sliding surface 2, that is keeps it adherent to the inclined portion 5a of the upper guiding surface 5, so that the hinge line 11b of the envelope matches the corner formed between the inclined portion 5a and the second portion 5b of the upper guiding surface 5.
  • the jet of air K going out of the holes 80b enters the envelope 10 opening, so as to raise the rear facing 10a of the envelope, the one with the flap, with respect to the front facing 10b, the one without the flap, until the rear facing 10a strikes against the second portion 5b of the upper guiding surface 5, to increase the envelope 10 opening section.
  • the lugs 3 convey the set of sheets 1 into the envelope 10, as shown in Figure 4, introducing it up to a predetermined point, in which the rear part 1b of the set of sheets 1 is beyond the hinge line 11b of the envelope 10.
  • the opening means 7 are deactivated and the lugs 3, overcoming the elastic reaction of the brushes 63, move forward the group C obtained by the introduction of the set of sheets 1 into the envelope 10, out of the enveloping station A, under the conveyor 28 and consequently, toward subsequent working stations.
  • the envelope ejection from the feeder 4 is similar, the envelope is guided into the sliding interspace T, so that the envelope front facing 10b touches the sliding surface 2, and consequently, the tail part 100 is intercepted by the stopping means 6.
  • the stopping means 6 define a movable stop, because: the arms 64, which involve the longitudinal slots 50, define an obstacle for the envelope 10 forward movement, and the counterbalances 65, lying against the removable stops 66, define the maximum lowering of the counterbalances 65, so as to maintain the working position of the arms 64.
  • the group C obtained by the introduction of the set of sheets 1 into the envelope 10, moves forward pulled by the lugs 3.
  • the high production rate is to be pointed out, obtained by high working speed and low number of downtimes.
