Definitions

  • the object of the present invention is formed from a machine for mechanically applying a ribbon provided inside envelopes and intended to open the latter when they are sealed.
  • FIG. 1 shows a perspective view of the machine of the invention showing the sliding upper plane surface
  • FIG. 2 is a diagrammatical view of the device for applying the ribbon in the initial position
  • FIG. 3 shows the same device in the instant of cutting the ribbon
  • FIG. 4 lastly shows the device for applying the ribbon in the position subsequent said cut
  • FIG. 5 shows in a top perspective view the device for taking off each envelope intended to reach the sliding plane
  • FIG. 6 shows in a perspective view a mechanical detail for opening the envelope in the instant in which the limb is only slightly lifted
  • FIG. 7 shows a perspective view of the same mechanical detail in the instant in which the envelope has the limb entirely opened to receive the opening ribbon;
  • FIG. 8 shows a perspective view of the device for applying the ribbon with the envelope in the open condition
  • FIG. 9 also shows diagrammatically in perspective the mechanical closing device for the limb of the envelope upon which the ribbon has been applied.
  • the invention concerns a machine 1 having mechanical-pneumatical device to perform automatically in a cycle involving a determined number of envelopes by removing and placing it on the sliding plane and causing each to move so as to obtain the application inside the envelope itself and preferably in correspondence of the inner fold of the closing limb of such envelope removed.
  • the upper plane of the machine 1 is preferably formed from three separate longitudinal sectors, of which the two lateral sectors 2 and 3 are generally stationary and the central sliding sector 4 having the main task of conveying the envelopes 6 pneumatically removed from the stack on the supporting plane 5 and caused to enter into cycle one after the other.
  • the sliding sector 4 which is no longer divided into three sectors, has a second horizontal plane or adhering device, parallel to the first plane, so that the envelope closed between the two movable surfaces, is held and compelled to perform the various movements.
  • Another important feature of the invention is formed from the use of a horizontal axis 7 carried on the whole length of the machine by suitably shaped supports 8, so as to maintain in a horizontal position a bar 9 situated slightly lower down than axis 7, the horizontal axis 7 having the function of supporting the arms 10 suitably distanced between each other and in accordance with the task which each of them is intended to accomplish, which arms 10 on the lower part carry the adhering plugs 14, to always maintain the envelopes perfectly adhering during the passage on the sliding plane 4, whereas the bar 9, instead, has the function to lift from the plane the arms 10 and simultaneously also the plugs 14, if necessity should arise.
  • Said arms 10 are free to slide as desired by the operator, so that they are adjustable in accordance with the surfaces of the envelopes and, of course, fastened by means of sleeves 15.
  • a feature of the invention resides in that the axis 7 and adhering plugs '14 moves in synchronism with the sliding plane 4 holding the envelope therebetween, no matter whether it is formed from only one surface of from two parallel or oblique surfaces, and this movement permits the arms 10 connected to said axis 7 to maintain in a preferably stationary horizontal position the envelope when travelling towards the device 17 to have applied thereto the tearing up ribbon.
  • Another important feature of the invention resides in the use of devices carrying pneumatic tubes 11 conveniently distributed and self-propelled, by means of which the envelopes are caused to adhere so as to be withdrawn and caused to enter the cycle with a view of applying the autoadhesive ribbon which inter alia requires also lifting of the closing limb of each envelope which is thus opened by the device 12, so as to permit the device 17 to apply the ribbon by exactly following the inner fold of said closing limb or any other limb of said envelope.
  • the device is substantially formed from a plate 17 suitably connected to an operating apparatus by means of a control axis 18 which, according to circumstances, will cause plate 17 to take up different positions which, as compared with that of FIG. 2, will preferably be sloping by 22 in FIG. 3 and then be straightened out (preferably in FIG. 4) to 10 at the instant of performing the cut of the ribbon.
  • a feature of the operation of plate 17 resides in the use of an arm 19, whose hammer-shaped head 20 is subdivided into two parts, of which the head 22 is stationary and the other is movable, or vice versa, so
  • Another feature of the invention resides in that the ribbon when moving towards the envelope undergoes a traction, preferably through pliers, which allows taking the said ribbon into its position of use without rumpling the envelope.
  • Plate 17 is provided at the upper part with a ribbonbearing roller 21 starting from a roller 25 carried by a rod 23 conveniently supported by a bearing 24 which terminates with a ribbon-bearing grooved pulley 25.
  • rollers 26 and 27 On the bottom of the plate there are provided two rollers 26 and 27 having preferably a derived motion since the controlled movement is furnished by rollers 28 located below the horizontal plane 30 of the machine 1, the front roller causing roller 27 to rotate by contact and the rear roller causing a last roller 29 to rotate by contact, between which rollers there is moving the open envelope intended to receive the adhesive ribbon.
  • a feature of the invention resides in the possibility of disposing of a preferably neutral ribbon 16 which, when moving to reach plate 17, receives a layer of adhesive substance on the outer side intended to not get into touch with the various rollers until the envelope 6 is reached.
  • the ribbon in question will be used with the already preexisting adhesive substance without thereby altering the operation of the plate and of the various rollers to perform the fixing operation on the envelopes.
  • the working of the machine according to the present invention is automatic and the envelopes laid on the stack plane 5 are caused to enter into cycle on the sliding plane 4 by means of a pneumatic tube 11 capable of describing a 90 angle from withdrawal to the position in which the envelope is laid down on the plane of the machine.
  • the envelope 6 is lifted by the pneumatic tube 11 which adheres outside the closing limb intended to receive the ribbon along the inner fold, the pneumatic arm performing a displacement of 90.
  • the envelope 6 With the second operation the envelope 6 is dragged along so as to perform the first forward movement on the plane of the machine and it is caused to undergo perforation preferably in the centre of the closing fold so as to provide a gripping point for the addressee when opening the envelope, said perforating device bearing the reference numeral 33.
  • the envelope which has already entered the cycle and is moving on the sliding plane, is dragged along with the limb slightly lifted, preferably by a suitable pneumatic arm 11 to prevent the first plug 14 to push down, besides the envelope, also the closing limb intended to be entirely open.
  • the device 12 FIG. 6, is provided on the stationary side part of the plane of the machine.
  • the envelope with the completely open limb and always dragged along on the sliding plane 4 of the machine is caused to undergo the application of the ribbon in its turn dragged along by the pincers 36, as well as the cut of said ribbon by means of mechanically operated scissors, whereas with the sixth operation the advertising label is applied inside the open envelopes so as to coincide with the perforation.
  • Ribbon 16 reaching from its suitably arranged coil enters pulley 25 carried by arm 23 and rotatably secured in 24, extends to pulley 21 through the head 20 and 22 to reach the base roller 27 after having engaged roller 26 as shown in FIG. 3.
  • the plate is moved back into an intermediate position at 10' (FIG. 5) whereupon, after having reached the vertical position of FIG. 3, the roller 27 is lowered so as to take advantage of the thrust of base roller 28 by opening the hammer-shaped head 20 and by restoring the same function as that provided for applying the ribbon on the incoming envelope, and
  • the envelopes are kept back on base 5 by means of a device 34 provided with a handle which maintains constant the plane of said envelopes to be withdrawn from the pneumatic tube 11.
  • a device 34 provided with a handle which maintains constant the plane of said envelopes to be withdrawn from the pneumatic tube 11.
  • the control device for operating the machine is shown by the reference numeral 35.
  • a machine for applying adhesive tape to the flap of an envelope having a tape applicator comprising a tape conveyor means, a support pivotable about a point above said envelope, and having a first, tape applying position, with a tape guide pulley mounted on said support for frictionally engaging an envelope fed past said tape applicator by said conveyor means, and applying thereto the said adhesive tape, and thereafter tape cutting position, having cutting means, said pulley being remote from said conveyor means and the tape cut by cutting means.
  • a machine as claimed in claim 1, wherein the support includes means for locking said adhesive tape when the support is in its second, tape cutting position.
  • a machine as claimed in claim 4 wherein, above said upper horizontal plane, are provided gripping means adapted to convey envelopes to spaced positions along said sector.
  • said means adapted to open said flap includes a pneumatic lifter capable of partially opening said envelope flap, and a deflector plate capable of completely opening the partially opened envelope flap.
