Definitions

  • the invention relates to a device for feeding packs of slips, such as labels (so-called blanks) or the like, in particular into cigarette packaging machines, and comprises: a feed hopper which can accommodate at least one pack of slips which is oriented substantially vertically, means for feeding packs of slips to the hopper, preferably from the top, and means for collecting the slips one after another from the base of the hopper.
  • the object of the invention is to produce a feed device of the type initially described, such that by relatively simple means, the operations of feeding packs of slips can be automated to a large extent, reducing manual service operations to a minimum, and to a very short period of time, and in particular if possible avoiding having to frequently interrupt the operative machine production cycle.
  • a device of the type initially described in which there is provided a store for a plurality of packs of slips, and which takes the packs one after another to a collection station in which the packs are oriented identically to the packs in the feed hopper, and are aligned with the latter in the same vertical plane, whereas means are provided for transferring one pack of slips at a time from the store to the feed hopper, which move the packs parallel to one another.
  • the store is advantageously of the type which rotates around a vertical axis which is parallel to the axis of the packs of labels, and is provided with a plurality of vertical peripheral cells, each of which accommodates one pack, the cells being oriented such that the pack of slips in the feed hopper and a pack of slips in the store, in a pre-determined position of rotation of the latter, are aligned on the same vertical side in the same vertical alignment plane, whereas means are provided for transferring in two directions at right angles to one another, preferably vertically and horizontally, and which move the packs along paths which are at least parallel to the said plane, and preferably along the said plane of vertical alignment.
  • the store can be disposed at a level lower than the feed hopper, and can be activated in rotational steps, taking each cell to a collection station, such that, by means of a lift, each pack is moved parallel to itself and on a vertical path as far as a horizontal translator which is provided in the same vertical plane as the lift, and at a level directly above the feed hopper.
  • the translator transfers each pack parallel to itself into a vertically coinciding position above the aperture of the feed hopper, whereas the pack is inserted in the feed hopper, parallel to itself, by being dropped.
  • the translator means and the lift means can be activated alternately in the two directions, travelling synchronously with one another a transport path and a return path.
  • the subject of the invention also consists of other features which further improve the above-described device, and which are the subject of the sub-claims.
  • a device for feeding packs of labels for example so-called blanks, to a hopper 1 for feeding the labels to an applicator unit of a packaging machine, comprises a store 2 for a plurality of packs P of labels, or the like.
  • the feed hopper 1 has an accommodation aperture with a cross-section which corresponds to the shape in plan view of the labels oriented vertically, such as to accommodate at least one vertical pack of labels.
  • the store 2 is mounted so as to rotate around a vertical access, and has co-axially to the axis of rotation a ring of peripheral cells 102.
  • the peripheral cells 102 are angularly equidistant to one another, and are oriented in the axial direction of the store 2.
  • the store 2 is rotated in steps by means of a drive unit generally indicated 4, taking the axial cells 102 to a collection station one after another.
  • each cell 102 is oriented such that the pack P of labels is parallel to the pack P of labels in the feed hopper 1, whereas the pack of labels P in the feed hopper 1, and the pack of labels in the cell 102 of the store 2 are aligned with one another on the same side, in a common vertical plane.
  • the axial cells 102 of the store 2 are open on the upper and lower head sides, and have a transverse cross-section, the profile of which complements the shape in plan view of the labels, at least corresponding to vertical strips along the angle areas which form guide and retention walls.
  • the packs of labels P are supported in the cells 102 by stationary support fins which project inside the aperture of the cells 102, overlapping the pack P of labels from beneath.
  • the said support fins 302 are provided on the base side of the cells 102, and only in the position of the angle areas of the transverse cross-sections of the cells 102.
  • the cells 102 are open along their entire axial length, on their radially outermost side, by means of an axial slot 402, through which there projects the free end of a horizontal support arm 8 of a lifting cage 7.
  • the arm 8 projects from a slide 5 which is mounted so as to slide on vertical guides, and is activated in a sliding manner in both directions by a motor M1 by means of a drive of the screw/nut-screw type, for example, generally indicated 6.
  • the lifting cage 7 and the cells 102 have shapes which are complementary to one another, such that the lifting cage 7 has an aperture for accommodating the pack of labels P, and can also move axially through the cells 102, passing from one side to the other of the rotary store 2.
  • the base 107 of the lifting cage 7 on which the labels are supported complements the transverse cross-section of the base side of the cells 102, in particular also with reference to the support fins 302.
  • the shapes of the cells 102 and the lifting cage 7 are advantageously such that they have complementary vertical wall areas which retain the pack of labels P laterally.
  • the vertical walls which retain the packs P laterally in the cells 102 consist of vertical wall strips which form the angle areas of the cells
  • the lifting cage 7 has vertical lateral retention rods 207 which are provided in the intermediate areas of the said vertical wall strips of the cells 102, in which position the cells 102 have lateral passage recesses 502 which extend from the upper side to the lower side of the cells 102.
  • the lateral retention rods 207 are attached to the base 107 of the lifting cage 7 by means of lateral extensions 307 of the support base 107 of the cage 7.
  • the structure of the rotary store 2 as described above is particularly simple when the store consists of a base plate with a circular shape indicated 602, in which there are provided openings which form the lower open side of the cells 102, whereas the lateral walls of the cells 102 consist of a ring of radial elements 702 which separate two adjacent cells 102 from one another, and the shape of which is such as to form the opposite inner walls of two adjacent cells 102.
  • the shape of the opening in the disc 602 is such that the disc is integral with the support fins 302 for the packs of labels.
  • a bushing 9 for coupling with a driven shaft 10.
  • the upper part of the bushing 9 ends in a grasping knob 109, whereas means 209, 309 are provided for detachable and snap locking of the store 2 on the shaft 10, both axially and relative to rotation of the store 2 together with the shaft 10.
  • the lifting cage 7 In the upper end of travel position, the lifting cage 7 is at a level higher than the upper edge of the feed hopper 1, whereas a horizontal translation transfer unit is provided in order to take the packs of labels P to the position of insertion into the feed hopper 1, by being dropped.
  • the horizontal transfer unit has a chamber 11 which is tubular or in the shape of a C, which is oriented vertically, similarly to the stack P of labels, is open at least at the base end, and has a transverse cross-section which is substantially complementary to, or slightly larger than the shape of the labels in plan view.
  • the transfer unit is at a level such that in the upper end of travel position, the lifting cage 7 penetrates fully inside the chamber 11, taking the pack P of labels into a position slightly higher than the base of the chamber 11.
  • the base of the transfer unit or of the chamber 11 is at a level directly above the upper feed mouth of the hopper 1.
  • the packs of labels must be fed inside the chamber 11 of the transfer unit by the lifting cage 7, whereas they must be retained in the transfer unit against dropping by gravity when the lifting cage 7 is moved away, on the base of the chamber 11 there are provided at least three and preferably four support fins 18 which are substantially the same as those 302 of the cells 102, and which can be detached or at least moved alternately from an active support position, in which they project inside the chambers 11, overlapping the pack P of labels from below ( Figure 10), to an inactive position in which they do not project beneath the pack P of labels ( Figure 9), permitting insertion from beneath with the lifting cage 7.
  • the removable support fins 18 are provided in each angle area of the chamber 11, and each of them is supported by an arm 19.
  • the fins 18 can preferably be moved in a direction transverse to the direction of transfer, being supported such that they project towards the chamber 11, each on the angled end of an associated arm 19 which is oriented in the direction of transfer, and which extends externally and parallel to the corresponding side of the chamber 11 in the direction of transfer, and along the lower edge.
  • the arms 19 end at the angle area, and are mounted on slides 20, 20' which are supported so as to slide in both directions transversely to the direction of transfer.
  • the slides 20, 20' consist of plates mounted in a sliding manner transversely to the direction of advance, and in the example illustrated they are guided so as to slide along the sides of the chamber 11 which are transverse to the direction of transfer.
  • the slides 20 are compressed by springs 21 in directions opposite to one another, and in particular in a direction of reciprocal approach. Consequently in a stable condition, the fins 18 are in an active position of supporting the pack of labels P.
  • the two opposite slides 20, 20' on each narrow side of the chamber 11 are shaped in the form of upper ridges opposite one another such as to form two opposite edges 120 which are inclined and diverge from one another upwards, and with these edges 120 there interacts a separator unit which comprises a roller-holder 122 separator head 22.
  • the head 22 is mounted on a vertical rod 222 which is activated by a thruster 17.
  • the separator head 22 is disposed on both of the narrow sides, transversely to the direction of transport of the chamber 11, whereas downward movement of the head against the opposite inclined surfaces 120 of the slides moves the arms 19 away, and thus provides distancing or displacement against the action of the resilient means 21 in the inactive position of the removable support fins 18 ( Figures 7 to 10).
  • a single thruster 17 which simultaneously controls both the separator heads 22, such that all the support fins 18 move substantially simultaneously into the active or inactive position.
  • the thruster 17 can be a pneumatic or hydraulic actuator cylinder or the like which is oriented with its rod 117 vertically, and which moves vertically a large fin 217 which interacts with the two upwardly projecting ends of the rods 222. In the lowered position of the large fin 17, the support fins 18 are open, whereas in the raised position of the large fin 217, the support fins 18 are in the active position.
  • the chamber 11 of the horizontal transfer unit projects onto a slide 12 which is engaged on two horizontal guides 13, 14 which are parallel to one another and vertically apart.
  • a belt 15 which is returned on pulleys 16, at least one of which is motorized, and has an upper section 115 which is horizontal and parallel to the guides 13, 14, and to which section 115 the slide 12 is attached at 112.
  • the upper guide 14 consists of an overturned U-shaped groove in which the slide 12 engages with at least one roller 212 which rotates around a vertical axis.
  • the transverse cross-sections of the cells 102, the lifting cage 7, the chambers 11 of the transfer unit, and the feed hopper 1, are not identical, but with reference to the path of the pack P of labels, the transverse cross-section of the said parts is gradually increased slightly, such as to prevent any slight offsetting of the labels in the packs P from causing obstacles or disruptions of passage of the packs P, and consequently incorrect positioning or jamming.
  • the rotary store 2 and in association with the latter the rotary drive unit generally indicated 4, can be mounted on a slide 25 which is supported such that it can be extracted outside the operative position on lateral guides 26, in order to enable the rotary store 2 to be moved away from the remaining operative parts of the machine (not shown in detail), and thus allow the store to be replaced more easily.
  • the slide 25 can be mounted notably on a double pair of guides, 26, 26'.
  • Figure 11 shows an embodiment in which on a beam or plate 27 which can rotate in the form of a turntable around a vertical axis, there are mounted two rotary stores 2, 2', each of which is provided with its own drive motor M2, M2'.
  • the axis of the plate 27 is in a position such that the innermost store 2' relative to the machine is operative, whereas the store 2 is in the rest position.
  • the empty store 2 can be easily replaced by a full store, whereas when the store 2' is empty, the position of the two stores, 2, 2' can be exchanged by rotating the plate 27 by means of the motor M3.
  • the full store 2 will go into the operative position, whereas the empty store 2' will go into the position in which it can be replaced by a full store.
  • the rotary store 2 advances by one step, taking the subsequent cell to the collection station only after the lifting cage 7 has completed the vertical transfer path of the previous pack P of labels from the rotary store 2 to the horizontal transfer unit, and has then returned to the position beneath the rotary store 2 through the empty cell 102 from which the pack P of labels has been taken.
  • the horizontal transfer unit travels the horizontal transfer path of the pack P of labels into the feed hopper 1.
  • the horizontal transfer unit 11 can return to the position of collection of the subsequent pack P of labels from the lifting cage 7, before the latter has reached the end part of the vertical transfer path. All of this can be carried out very quickly, and in a time which corresponds to a pre-determined partial use of the stack of labels in the feed hopper 1. Rotation of the store 2, drive of the horizontal transfer unit and that of the lift are advantageously independent of one another, whereas synchronization is provided by an electronic control circuit to which the supply units of the motors and the movement detection sensors of the said parts are connected.
