Definitions

  • This disclosure relates to an apparatus for the distribution of a succession of sheets of paper, labels or similar, comprising a fixed hopper to receive a pile of sheets of paper, a movable support base for said pile, underneath said hopper, circuit means for putting said support base in communication with a suction source for removing the last of the sheets of papers from the pile; retaining it on the support base for a pro-established time period and transferring it to successive stations, in consequence of the movement of said support base.
  • This invention relates to an apparatus for the distribution or the dispensing in succession of sheets of paper, labels and similar, assembled in piles, particularly for the feeding of conditioning machines in general, paper packaging machines and similar.
  • the present invention proposes to provide an apparatus for the distribution of sheets of paper, labels and similar which will be able to achieve high working speeds thus distributing a high number of sheets of paper or labels per time unit.
  • a further object of this invention is to devise an apparatus in which the masses subjected to reciprocal movements are reduced in substantial measure, thus reducing in consequence the inertia which, in conventional apparatuses, resulted in the impossibility of achieving satisfactory working speeds.
  • a further object of this invention is to devise an apparatus which will not require the continual movement of all the sheets of paper grouped in piles, during the distribution of them in succession.
  • the piles of paper can in fact reach considerable weights, for which in the similar apparatuses a remarkable portion of the. energy re quired for the working is absorbed by the members which determine the movement of said pile.
  • an apparatus for the distribution of a succession of sheets of paper, labels or similar which is characterized in that it comprises a fixed hopper to receive a pile of sheets of papers, a support base for said pile, underneath said hopper and formed of a plane surface support and a cylindrical surface having an axis which is parallel and underneath said plane surface, and being tangential to said plane surface, means capable of translating cyclically, reciprocally and in rigid connection relationship said plane and cylindrical surface in a direction which is perpendicular to said axis, means capable of reciprocally rotating said cylindrical surface about its own axis, in phase with said reciprocal translatory movement, circuit means for putting said cylindrical surface in communication with a suction source, interception members for cyclically obtaining said communication in phase relationship with said rotation and translation, the cycle comprising the phase of removing the last of the sheets of papers from the pile, retaining it on the cylindrical surface when said interception members establish the communication, transferring it to successive stations, in
  • FIG. 1 shows the apparatus according to the invention part in view and part in vertical and longitudinal sections according to different sectional planes, in its application to a conditioning machine;
  • FIG. 2 shows the apparatus of FIG. 1 part in view and part in vertical cross-sections according to different positions.
  • the motion means linking and controlling devices for the transmission of the movement from the primary motion source to the principal members may be derived, for example, from the main shaft of a conditioning machine, not shown, or from any other source.
  • This machine may be, in order to give an idea, a cigarette packing machine.
  • a similar derivation may be obtained for example by means of a system of transmission chains and chain wheels.
  • the reference numeral 1 is used therefore to indicate a transmission chain would on a chain Wheel 2 keyed onto a shaft 3, which is consequently caused to rotate.
  • the sheets of paper or labels are piled inside a hopper 7 delimited by the pairs of plane and parallel walls 8 and 9 and 10, 11.
  • the walls 10 and 11 are provided in the proximity of the base, with slide members 12 and 13 respectively, regularly positionable by means of locking screws 14 and 15 on the body 16 of the apparatus (see FIG. .2).
  • the walls 8 and 9 have instead slide members 17 sliding on the guide 18 attached to the slide 13, so as to be able to be distanced according to the requirements, that is definitively according to the dimensions of the sheets of paper.
  • On the guide 18 there are graduated steps 19 and 20 which are put in relationship with the pointers 21 which are on the movable slides 17.
  • a senser 22 of known type formed for example of a control microswitch member 2211 in connection with a suitable signaling circuit. This for the purpose of signaling rapidly the exhaustion of the pile of sheets of paper, so that the hopper is recharged.
  • the bottom base of the hopper is formed of a rotating element.
  • Said rotating element is supported by a tube 23 parallel to the shaft 3 and sliding transversally to the structure of the machine sliding in the horizontal slit 24.
  • a bracket 25 which supports at the level of the bottom of the hopper two longitudinally aligned planes 26 and 27, which are interspaced in the sense of alignment.
  • the tube 23 has a horizontal reciprocal movement, along the slit 24, obtained by means of a rod and crank transmission carried out in the fol lowing manner: to the tube 23 is connected the small end 28 of a connecting rod 29 whose big end 30 is eccentrically attached, in 31, to a wheel 32 attached to said shaft 3.
  • a rotating shaft 33 Inside the pipe 23 is situated a rotating shaft 33 whose end, provided with a roller 34, is guided into a horizontal groove 35 parallel to said slit 24.
  • a roller 34 At the opposite end of the shaft 33, outside the structure of the apparatus, isattached the hub 36 of a sector wheel 37 which consequently rotates in rigid relationship with the shaft 33.
  • Peripherally such sector wheel is shaped so as to define a cylindrical wall 38 having a length, or development in the direction of the generatrix, substantially corresponding to the transverse length of the planes 26 and 27. Moreover the same wheel is maintained at a tangent to the common plane of the planes 26 and 27, in relation to the area in which they are distanced, thus constituting in practice a junction between the planes themselves in rela tion to the discontinuity included between them.
  • the wheel 37 is furthermore provided with a spoke 39 inside which is obtained a cavity which develops radially, said cavity being in communication at an end with the outside, in 39a in correspondence with the surface 38, and which at the other end, that is in correspondence with the hub, connects with the final section of a pipe which will be more fully described later.
  • a cog-wheel 40 is furthermore rigidly mounted, which meshes with a rack of rectilinear development parallel to that of the slit 24. It may be understood that, by means of the connection of the tube 23, through the connecting rod 29, to the wheel 32, a horizontal reciprocal translational movement of the shaft 33 is obtained, and thus of the bracket 25, of the planes 26 and 27 and also of the wheel 37.
  • a further horizontal coupling 42 moreover connects with the tube 23 and develops with respect to the latter, in a parallel direction: it is namely orientated according to the horizontal translational movement of the tube 23.
  • the coupling 42- is co-axial and external with respect to a pipe 43 connected, through a union 44, to suctions means, not shown, the connection comprising interception means designed to put the pipe 43 cyclically in connection with said suction means.
  • Said cylindrical chamber 46 communicates in turn, through a hole 47, with an axial pipe 48 obtained within the shaft 33, said pipe being put in communication with the radial cavity of spoke 39 and hence with the outside of the apparatus in relation to the cylindrical surface 38, as has already been seen previously.
  • roller 50 On the shaft 6 are keyed a roller 50 and a cam 51. Against said roller 50 are maintained in elastic engagement the rollers 52, 53 and 54 which are moreover caused to rotate by the same roller 5
  • the roller 52 rotates about its own shaft 55 carried by a radial arm 56 fixed at one end 57 to the shaft 58.
  • a radial arm 59 At the opposite end of said shaft 58 is fixed a radial arm 59 to which is connected the end of spiral spring 60 whose other end is fixed in 61 to the fixed frame. Due to such positionings, the roller 52 is, in normal positions, in spring-biased engagement with the surface of the roller 50, but the pivoting shaft 58 can rotate in contrast to the spring 60, thus permitting a relative spacing between said roller 52 and roller 50.
  • the rollers 53 and 54 are mounted on the rocker levers 62 and 63 respectively, pivoted on the same cornmon shaft 64 and cooperating respectively with the helical springs 65 and 66 which tend to maintain said rollers 53 and 54 pressed
  • the cam 51 is intended to control the interception members mentioned above, of the suction circuit.
  • These members comprise a union coupling 67 connected to a suction pipe 68 coming from the suction elements, not shown.
  • a fixed pipe 69 whose end section 70 is positioned cyclically in communication with a section of mobile pipe 71 which, through the union 72 and the tubing 73, is connected to the union 44 of the pipe 43 previously described.
  • the same pipe 71 is formed inside of a sleeve member 74 sliding held in a fixed seat 75, in co-operation with the compressed helical spring.
  • the axial movement of such sleeve member 74 is determined by the coupling between a wheel 77, revolving about the shaft 78 connected with a fork extension of said member 74, and the cam 51.
  • the wheel 77 is held in engagement with the profile of the cam 51 by the thrust action of the spring 76.
  • the sleeve or union 74 is connected to an alternate movement inside the seat 75, thereby putting periodically in communication the suction source with the inside of the pipe 43, and thus after all, through the successive communications previously described, with the outside of the surface of the sector wheel 37, in correspondence to the spoke 39.
  • the pile of sheets of paper or labels is positioned inside the hopper 7, and lays on the movable bottom of the latter.
  • the tube is in correspondence with the left end of the slit 24, consequently the bottom of the hopper is formed of the plane 27.
  • the sector wheel 37 is positioned in fashion such as to have the exit hole of the suction pipe practically arranged to correspond with the bottom of the pile, and thus adjacent to the bottom surface of the sheet of paper to be removed.
  • the relation of phase is such that, when the spoke 39 is in an almost vertical position, and thus when the suction pipe flows, as has been said previously, in relationship to the bottom surface of the label or sheet of paper to be removed, correspondingly the cam 51 allows the sleeve 74 to move towards the right, under the action of the spring 76 so as to effect the communication between the pipe 71 and the pipe 70.
  • the suction determined by suction means, not shown, situated above the pipe 68 is transmitted through the pipe sections 69, 70, 71, 73, 43, 45 44a, 46, 47, 48 and 39 in correspondence with the last sheet of paper of the pile, and thus of the sheet to be removed.
  • the vacuum causes the sheet of paper to be retained on the cylindrical surface 38 which carries it along with it in its rotatory-translatory movement.
  • the sheet remains layed flat and is carried along with it by the wheel 37 until it is transferred in proximity of the region of the transferring roller 50.
  • the apparatus in question may be used in a great many fields which demand cyclical distribution of sheets of paper or labels in succession.
  • it has an advantageous application in the conditioning machines in general having a high speed of production, and particularly in packing machines, papering machines and similar for cigarettes.
  • An apparatus for the distribution of a succession of sheets of paper, labels or similar which is characterized in that it comprises a fixed hopper to receive a pile of sheets of paper, a support base for said pile, underneath said hopper and formed of a plane surface support and a cylindrical surface, having an axis which is parallel and underneath said plane surface and being tangential to said plane surface, means capable of translating cyclically, reciprocally and in rigid connection relationship said plane and cylindrical surface in a direction which is perpendicular to said axis, means capable of reciprocally rotating said cylindrical surface about its own axis, in phase with said reciprocal movement, circuit means for putting said cylindrical surface in communication with a suction source, interception members for cyclically obtaining said communication in phase relationship with said rotation and said translation, the cycle comprising the phase of removing the last of the sheets of paper from the pile; retaining it on the cylindrical surface when said interception members establish the communication; transferring it to successive stations, in consequence of the translation and rotation, and leaving it when communication is stopped.
  • said interception means comprise a hollow sleeve communicating through said circuital means with said cylindrical surface and cooperating with eccentric means so as to slide axially and reciprocally in a fixed sleeve, said fixed sleeve defining inside it a pipe communicating with the suction source and, cyclically, with said hollow sleeve.
