Definitions

  • the present invention relates to automatic or semiautomatic machines for inserting stacked groups of sheets into envelopes.
  • the present invention relates to a machine for inserting sheets into envelope, the machine including means for storing a stack of envelopes, means for sequentially removing the envelopes from the storing means, means for conveying the envelopes in a travel path, means for opening the envelopes, means for forming groups of stacked sheets, means for grouping and conveying the sheets to be inserted and means for inserting the groups of sheets into the envelopes.
  • the machines for inserting sheets into envelopes include a running plane, on which the sheets are dropped by sheet feeder devices, which are arranged above the running plane.
  • Conveying means, disposed along the running plane, are operated, in step relation with the release of the sheets on the running plane, so as to transfer the group of stacked sheets to a sheet insertion station.
  • An envelope feeder is situated above the running plane close to the sheet insertion station, which feeds the envelopes to the running plane.
  • Suitable opening means such as air jet ejectors open the envelopes, in order to allow the insertion of the group of sheets moved by the conveying means.
  • the envelopes delivered by the envelope feeder to the running plane at the sheet insertion station have the back wall (address side), i.e. the wall to which the closing flap is hinged, turned upwards; consequently, the opening through which the sheets are inserted is turned downwards, thus, hidden by the closing flap.
  • the operator must overturn the faulty envelope, re-position correctly the sheets, overturn again the envelope, and re-instate it into the forward travel path of the machine.
  • the maximum number of envelopes stacked inside the envelope feeder is lower than the sheets stacked in each sheet feeder.
  • an higher stack of envelopes cannot be formed inside the envelope feeder because loading would be difficult for the operator, who should replenish the envelope feeder at too high level, above the running plane.
  • the main object of the present invention is to propose a continuously operating machine for inserting sheets into envelopes, which inserts sheets into envelops while allowing a direct sight of the insertion operation.
  • Another object of the present invention is to propose a machine for inserting sheets into envelopes, which is extremely reliable in relation to envelopes feeding operation, as well as in relation to the insertion of the sheets, and which can operate without feeder replenishment necessity for a longer time.
  • the reference sing M indicates the whole machine for inserting sheets into envelopes, proposed by the present invention.
  • the envelope filling machine M includes (as shown for instance in Figure 1) sheet feeder means D, which place the sheets F on a running plane S situated below.
  • Driving means T are disposed and operated along the running plane S by a relative conveying line T1 situated therebelow and engage the trailing edge of the group of stacked sheets, in order to convey them to an sheet insertion station I, situated along the running plane S downstream of the conveying line T1.
  • a first characteristic of the proposed envelope filling machine M lies in the fact that, the envelope feeder 1, containing a stack of envelopes, is situated beside the running plane S.
  • the outlet section U of the envelope feeder 1 is situated at a level lower with respect to the running plane S and to the sheet insertion station I.
  • the envelope filling machine proposed by the present invention can undoubtedly operate without necessity of replenishment of the envelope feeder for a time longer than the machines of prior art.
  • the envelope feeder 1 is aimed at removing continuously single envelopes from the base of the stack P and at feeding them to the inlet A of an additional conveying line 2, arranging the single envelopes 10 in such a way that their back wall 11 (address side), that is the wall to which the closing flap 13 is hinged, is turned downward.
  • the envelope opening 12, for insertion of the sheets F is turned upward and backward with respect to the inlet A of the additional conveying line 2 ( Figures 4-and 5).
  • the envelope feeder 1 includes removing means (not shown and described in detail since they are of known type), which are aimed at removing continuously single envelopes from the base of the envelopes stack, and at turning them by 180° (arrow W in Figure 4), in order to carry them toward the inlet station A of the additional conveying line 2 in the above described configuration.
  • the additional conveying line 2 extends between the envelope feeder 1 and the above mentioned sheet insertion station I and is equipped with gripping means 3, arranged spaced out according to a selected step and aimed at taking over single envelopes 10 and at transferring them, maintained in the above mentioned configuration and suitably earlier with respect to the arrival of respective sheets F, to the sheet insertion station I.
  • the additional conveying line 2 transfers the envelopes, placing them in the sheet insertion station I downstream of the running plane.
  • the envelopes are released with their back wall (address side) 11 and their closing flap 13 turned downward, so that the opening 12 for inserting the sheets F is turned upwards and toward the terminal part TS of the conveying line T1 of the conveying means T, crosswise to the running plane S ( Figures 6a and 6b).
  • the additional conveying line 2 can for instance include a first horizontal straight section A1 ( Figures 4 and 5), which extends from the outlet portion U of the envelope feeder 1 toward the running plane S, below the latter, a second curved section A2, which arranges the envelopes, for instance by 90° rotation, substantially in alignment relation with the running plane S, a third horizontal straight section A3 ( Figure 4 and Figures 6a and 6b), which is parallel and situated below the running plane S, a fourth ascending section A4, downstream of the terminal part TS, and a final horizontal straight section A5, following the running plane S and adjoining the sheet insertion station I.
  • a first horizontal straight section A1 Figures 4 and 5
  • a second curved section A2 which arranges the envelopes, for instance by 90° rotation, substantially in alignment relation with the running plane S
  • a third horizontal straight section A3 Figure 4 and Figures 6a and 6b
  • a fourth ascending section A4 downstream of the terminal part TS
  • a final horizontal straight section A5 following the running plane S and adjoining
  • the additional conveying line 2 includes endless conveying means 20 (e.g. a chain), to which the above mentioned gripping means 3 are connected, with a working forward run 21 for transferring the envelopes and defining, one after another, the above described first A1, second A2, third A3, fourth A4 and fifth A5 sections, and a return run 22, which completes the endless loop.
  • endless conveying means 20 e.g. a chain
  • the additional conveying line 2 transfers and places the envelopes, previously removed from the envelope feeder, along the running plane S and in the sheet insertion station I in such a configuration that the opening of the envelopes are turned upwards. This allows advantageously an operator to verify the correct envelop filling operations, and to perform a direct visual check on the inlet section.
  • Each of the gripping means 3 of the additional conveying line 2 include a pair of gripping arms 31, 32, pivoted to each other and arranged normally in clamped configuration.
  • Suitable first wide opening means 4 situated near the inlet section A of the additional conveying line 2, are aimed at engaging temporarily a first arm 31 of the gripping arms 31, 32 which is moving along the area of the section A, in order to open the first arm with respect to the second arm 32.
  • This opening allows introduction of the bottom edge 14, opposite to the edge with the closing flap 13, of an envelope 10 released by the outlet section U of the envelope feeder 1 between the arms 31, 32. Then the edge remains gripped between the arms due to releasing of the first arm 31 by the first wide opening means 4.
  • the first wide opening means 4 include for instance (as shown in detail in Figure 5) stationary cam means 41, suitably shaped, and aimed at temporarily engaging a corresponding striking means 42, connected to the first arm 31 of the gripping means 3. Striking of the striking means 42 on the cam means 41 determines the temporary opening of the first arm 31 with respect to the second arm 32.
  • the striking means 42 include, for instance (as shown in the same Figure 5), an idle roller connected to the first arm 31 of each of the gripping means 3.
  • First means 5 for opening the closing flap 13 of the envelopes 10 are situated along the additional conveying line 2, following the first wide opening means 4, and are aimed at opening the flap 13 in suitable step relation with the passage of the single envelopes 10 dragged by the gripping means 3.
  • the first opening means 5 include vertical nozzles, which are aimed at directing flows of air toward the envelopes passing below, so that one component of the flow of air acts on the flap 13 of the envelopes 10 in order to open it and consequently to widen the opening 12.
  • the above mentioned sheet insertion station I includes (as shown in detail in Figures 6a and 6b): a filling place 50, situated along the running plane S downstream of the terminal section TS of the conveying line T1 of the conveying means T.
  • the filling place receives single envelopes 10 to be filled from the additional conveying line 2 and means 51 retain the single envelopes 10 stopped dwelling in the above mentioned filling place 50 while inserting the sheets F.
  • Second means 52 open the closing flap 13 and keep the latter in open configuration.
  • the second means also part the back wall 11 of the single envelopes 10 away from the front wall 16, in order to increase the opening section during dwelling.
  • Transferring and inserting means 53 situated and acting above the filling place 50, take over the sheets F, in step relation with the release of the sheets F by the conveying means T in the region corresponding to the terminal section of the relative conveying line T1, by acting on the respective trailing edges.
  • the transferring and inserting means 53 transfer the sheets F to said filling place 50 and insert the sheets F into the single dwelling envelopes 10, up to a predetermined point, in which the trailing edges of the sheets F is located beyond the hinge line of the flap of the envelopes 10.
  • the transferring and inserting means 53 are also aimed at transferring the envelopes 10, after the sheets have been completely inserted therein, from the filling place 50 toward subsequent working stations, in order to free the filling place 50 for further single envelopes to be filled.
  • the transferring and inserting means 53 are operated by an endless conveying device 55, suitably situated above the running plane S, whose upstream section 56 is situated in the region corresponding to the terminal section TS of the conveying line T1 of the conveying means T.
  • the transferring and inserting means 53 take over, in suitable step relation with the release of the sheets by the conveying means T, the sheets in order to transfer them to the filling place 50, to introduce them into the envelopes dwelling therein and then, to transfer the envelopes together with the relative sheets toward subsequent working stations (not shown).
  • the above mentioned second opening means 52 include vertical nozzles, which direst flows of air toward the envelopes dwelling below, so that one component of the flow acts on the closing flap 13 in order to widen the single envelopes opening 12 and facilitate the insertion of the sheets F.
  • the retaining means 51 can include (as shown in the proposed Figures) arms kept in vertical configuration by relative contrast means, for instance counterweight, (not shown), to keep the envelopes 10 dwelling in the filling place 50 during the insertion of the sheets F; the arms are aimed at being partially raised, in order to free the single envelopes 10 due to the continuative pulling action of the transferring and inserting means 53, so as to transfer the single envelopes 10 with the sheets F inserted therein toward subsequent working stations.
  • relative contrast means for instance counterweight, (not shown)
  • Second means 6 for opening the gripping arms 31, 32 of the additional conveying line 2 while passing by the filling place 50, are situated in the sheet insertion station I in order to release the envelopes when it is positioned in the filling place 50.
  • the second wide opening means 6 include stationary cam means, suitably shaped, aimed at temporarily engaging the idle rollers, connected to the first arm 31 of the gripping means 3.
  • the run of the rollers on the cam means determines a temporary opening of the first arm 31 with respect to the second arm 32 and the release of the envelopes 10.
  • the proposed machine for inserting sheets into envelopes can direct and arrange the envelopes to be filled with sheets in such a way that the opening is turned upward, directly seen by the operator checking the machine correct operation.
  • the proposed machine can wok without replenishment for a time longer than the machines of the prior art, due to the advantageous positioning of the envelope feeder beside the sheets running plane, and the relative outlet section at a lower level with respect to the running plane.
