Definitions

  • the invention relates to a device for feeding-singularizing of blanks, labels, or similar, in particular in a cigarette packing machine, according to the preamble of claim 1.
  • All this known devices typically comprise at least a pick up and transfer module which is interposed between the discharge opening of a feed hopper and conveyor means.
  • the pick up and transfer means have transfer heads which pick the last blank of a stack of blanks housed in the feed hopper and transfer each blank to the conveyor which transports the single blanks to the further operating units for example of a packing or wrapping machine.
  • the pick up and transfer modules are synchronized with the conveyor.
  • the invention has therefore the aim to make a device of the type described at the beginning, that thanks to a relative simple construction can ensure the maximum operational reliability and allows to reach high working speeds without excessively weighing down the dimensioning of the drive kinematics and the drive motor.
  • the invention attains the above aims with a device according to the preamble of claim 1 and further showing the features of the characterising part of claim 1.
  • At least one pick up/transfer module is provided in combination with means which vary at least the component of motion of the same in direction of advancement of the conveyor in such a manner that upon depositing the blank on said conveyor , the pick up module and the blank it carries have the same speed in the direction of advancement of the conveyor itself.
  • the variator means of the speed of the motion at least in one component of the motion are made in such a manner to eventually vary also the speed of one or both the motion components of the circular motion in order to ensure a stable relative positioning of the pick up/transfer means and of the feeder at least during the pick up phase of the blank from the said feeder.
  • the pick up/transfer assembly is formed by a support module that is guided on the circular track by conveying means with a constant speed of rotation, while the pick up/transfer head is mounted movable at least in direction of one of the two components of the circular motion, preferably according to both the components of the circular motion relative to the support module by variator means of the speed of advancement of the said head with regards to the associated support module.
  • One particularly advantageous configuration provides for the direction of pick up of the blanks from the feeder to be perpendicular or in any case transversal to the direction of advancement of the conveyor.
  • One form of execution of this configuration in particular, provides for a hopper for feeding the blanks vertically oriented and with a discharge opening at the bottom end, the said discharge opening overlaps at a certain distance the input or loading end of a band conveyor the direction of conveyance of which is horizontal, while the circular track of at least one pick up/transfer module has a vertical and a horizontal motion cvomponent and the axis of rotation is provided on the side of the track of conveyance of the conveyor opposite to the feed hopper.
  • the pick up/transfer means have additional pick up/transfer modules that are distributed angularly equidistant along the circular track.
  • the means that vary the speed components of the pick up/transfer heads of the individual pick up modules are connected to the modules themselves and move together with the same on the circular track.
  • a preferred form of execution provides for the pick up/transfer module each of which is formed by a support module and of at least one pick up/transfer head that is articulated on the support module by means of a set of levers, in order to form an articulated quadrilateral and the said levers are articulated to small shafts distanced from each other and which are freely supported turning in the support module and are provided along the sides of said support module transversally to the direction of advancement, on the front and the rear with regards to the direction of advancement, at least one of these articulated levers constitutes the drive lever of the articulated quadrilateral and is mounted turning together with its shaft that dynamically engages rotary wise with the rotary drive of the same that turn coaxially to the circular track of the pick up/transfer modules and that can be activated turning with a speed and/or direction of rotation different from the one of the pick up/transfer modules along their circular track.
  • the differential rotation of the means driving the rotation of the shafts associated with the drive lever of the articulated quadrilaterals allows to give to the pick up/transfer head differental drive components both radially and tangentially with regards to the components of the motion along the circular track of advancement of the support modules.
  • a suitable staggering of the speed of rotation of the activating means of the driven levers allows to substantially cancel the component of horizontal motion in the position of pick up of the blank from the bottom of the hopper.
  • the tangential component substantially horizontal and in the direction of advancement is being cancelled by the backward motion of the pick up/transfer head due to the activation of the articulated quadrilateral, therefore the said head carries out substantially a movement parallel to the axis of the hopper or to the direction of discharge of the blank from the same.
  • the speed of the pick up/transfer modules along the circular track is regulated in such a manner, that the component of motion of the pick up/transfer heads in direction of advancement of the band is identical to the speed of advancement of the band without the requirement of an additional increase of the drive speed of said heads relative to the motion on the circular track of the support modules.
  • An additional relative motion of the pick up/transfer head may be required in a variation.
  • the differential rotation of the means driving the articulated parallelograms involve apart from the vertical motion of nearing the blank to the band conveyor a positive or negative acceleration in the horizontal direction of advancement relative to the standard horizontal component of the circular motion of advancement of the pick up/transfer modules.
  • the two components of motion add up between themselves making the speed of the pick up/transfer head identical to the one of the bands at the moment of transfer of the blank onto the band conveyor.
  • the pick up/transfer modules in form of an articulated parallelogram are supported by driving means along the circular track such, that the support module moves along the circular track keeping always one single orientation, in particular a horizontal orientation with reference to the plane containing the axis of the two shafts.
  • the pick up/transfer heads have always the same orientation, in particular an orientation parallel to the one of the support module as far as the axes of articulation of the pick up/transfer heads to the corresponding extremities of the two levers of articulation are concerned.
  • Such arrangement is advantageously obtained by driving means of the pick up/transfer modules formed by two discs with axes parallel to the shafts of articulation and drive associated with the support modules, one of the two shafts being supported turning freely only in one disc, while the other shaft is supported turning freely only in the other disc and as the two discs are parallel to each other, but with axes staggered to each other in a dimension corresponding to the distance between the shafts connected to the support module of the pick up/transfer modules at least one of these discs is rotary driven, while the other is idle.
  • the supporting module has a length in the axial direction of the discs that is substantially corresponding to the dimensions of the blank in said direction, while each support module carries two, three or more pick up/transfer heads identical to each other and placed side by side at a certain distance from each other, the said pick up/transfer heads are each articulated with their own articulating levers to the same shafts of articulation and drive connected to the the support module and that have a corresponding axial extension.
  • the band conveyors has advantageously a pair of bands designed to engage with the end areas of the blanks, forming a free zone for the passage of one or more of the pick up /transfer heads, while the two bands have top teeth or ribs that form front and rear stops with the corresponding edges of the blank.
  • the band conveyor can have in position of noninterference with the free passage of the pick up/transfer heads one or a pair or more aditional retaining bands parallel to each other and to the toothed conveyor bands which are additionally under suction, in order to hold the blanks effectively in the position of engagement between the front and rear stop teeth of the bands during advancement on the same.
  • Each pick up/transfer head is under suction, the connecting conduits to the source of vacuum passing through the free shaft associated with the support module and that extends itself into a circular distributor, while subsequently it is made to pass through the support module in the drive shaft and through the same into the drive levers rotary integral with this latter, while the conduits made in the drive levers open into a plenum chamber in the corresponding pick up/transfer head from which the vacuum is distributed to the suction nozzle or nozzles or to the suction cup or caps.
  • each pick up/transfer head has a body to which the levers are articulated and that carries at least one or more suction cups or suction nozzles.
  • a narrowing of the hopper is provided in such a manner that the last blank takes up an arched position, separating itself in the middle from the once above.
  • Said narrowings are preferably provided on the sides of the hopper mouth which are transversally to the direction of advancement of the band conveyor.
  • the suction pad or pads can have means of motion that determine a sliding in the axial direction of the hopper with a very rapid stroke and that takes place relative to the body of the pick up/transfer head.
  • the end conduit of connection to the source of vacuum is made in shape of a cylindrical chamber and houses within in a sealed sliding manner and against the action of a spring part pushing the supporting rod of the suction cup outwards which is itself also cylindrical.
  • the suction cup comes into contact with the blank, the suction is no longer free through it and can act against the action of the spring part in the sense of recalling the rod of the suction cup to its innermost postion.
  • the suction cup is therefore made to sharply move away for a certain dimension limited by the exit of the hopper, as the stroke is commensurate in a manner sufficient to free the blank from the tightening at the exit of the hopper itself.
  • the device according to the invention allows furthermore to work with a plurality of pick up/transfer modules that succeed each other in a continuous manner and which allow to to reduce the speed of movement od siad modules on the circular path. This allows for the reduction of the speed of advancement of the pick up/transfer modules on the circular track to such levels as to minimize the differences in speed to be applied to the pick up/transfer heads to obtain the desired behaviour of motion and to avoid excessive driving speeds of the pick up modules.
  • the Fig. 1 shows a plan view from above partially in cross section of the device according to the invention.
  • Fig.s 2 and 3 illustrate two enlarged areas of Fig. 1.
  • Fig.s 4 to 9 illustrate schematically the pick up and transfer cycles of the blank with the device according to the preceding Fig.s.
  • the Fig.s 10 and 11 show two enlarged details similar to the Fig.s 4 to 9 with the pick up/transfer modules in two cycles of pick up of the blank at the discharge end of the hopper.
