Definitions

  • This disclosure relates to an automatic apparatus for drying the glued portions ofand for transferringthe packets of cigarettes egressing from a packing machine, comprising at least one column for receiving, in piles, the packets at the base of said column, the packets introduced in the column rising therein step by step and reaching the top of the column after the necessary drying time.
  • This invention refers to an automatic apparatus for the drying of the glueing and the transfer of packets of cigarettes and the like coming from the exit of a packing machine or similar in which they are subjected to successive operations of paperpacking (wrapping) and glueing.
  • the automatic conditioning machine for conditioning cigarettes in packets provides for a succession of operations during which the preparation, folding and glueing of different materials occurs, intended to constitute the various layers of the envelope components of the packet itself. Because the materials intended to constitute the envelopes are, as has been said, glued in a predetermined area, so as to be able to shape, after the folding, the envelope itself, it is necessary, at the end of the operation of conditioning, to dry the glueing material.
  • a principal object of the invention is to obviate the above-mentioned inconveniences by providing an automatic apparatus in which the drying of the glueing material occurs without having to resort to the use of ambient heat, and in consequence of heating elements, by this liberating the production cycle of the packets of cigarettes from these inconveniences.
  • Another object of the present invention is to provide an apparatus in which the packets of cigarettes are constantly guided, during their movement inside the apparatus itself, and in which the glued areas are constantly subjected to pressure action which prevents the possibility of accidental separation of the glued edges, for example because of an insufficiency of glue.
  • a further object of the present invention is to provide an apparatus which allows the transfer and drying of an increased number of packets per unit time, so that 3,508,381 Patented Apr. 28, 1970 the apparatus may be usefully associated with a conditioning machine having a great packing production speed.
  • a further purpose of the present invention is that of providing an apparatus which during the drying of the packets does not submit the packets themselves, and in consequence the cigarettes contained inside them, to any harmful stress, especially in an axial direction with respect to the cigarettes, thus guaranteeing the absolute integrity of the form of the contents of the cigarettes them selves.
  • an automatic apparatus for the transfer of packets of cigarettes from the lined of exit of a packing machine or the like which is characterized, from a general point of view, in that it comprises at least one column at the point of the exit of said line, means for the introduction of the packets proceeding from the packing machine to the base of said column, and underneath the previously introduced packets, so that they appear to be in superimposed arrangements inside the column, the packets already introduced rising step by step with the introduction of successive packets and reaching the top of the column after a time suitable for obtaining the drying of the glue of the packets.
  • the automatic apparatus comprises at least a pair of chambers, in side by side arrangement, capable of each receiving one packet of cigarettes, means to place said chambers alternately in alignment with the line of exit of the packets from the packing machine in synchronism with their progress pace, at least one pair of columns to house superimposed packets, each column overhanging one of the chambers of said pair of chambers when second of said chambers is in alignment with the line of exit of the packets spring means beneath said column, and capable of raising the packet received in one of said chambers, when the second of said chambers, is in alignment with the line of exit of the packets and to insert it into the base of said overhanging column, means for retaining the superimposed packets beneath the bases of said columns, the packets of cigarettes rising inside the column at a rate with the introduction of other packets to the base, and remaining there for an interval of time such as to effect the drying of the glued areas of the packets.
  • FIG. 1 shows part in view and part in vertical longitudinal sections according to different planes, the members which distribute the packets to the drying columns;
  • FIG. 2 shows the same members in vertical and trasversal section.
  • FIGS. 3 and 4 respectively show the areas below and above the drying column, part in view and part in vertical cross section according to different planes and FIGS. 5 and 6, show the same areas illustrated respectively in FIGS. 3 and 4, part in view and part in vertical longitudinal section.
  • the apparatus according to the invention is situated at the end of the line of conditioning of a packet forming machine, and is disposed so as to -be able to receive the packets which, at the exit of said line, are conveyed in file, as the successive packets are formed.
  • the apparatus comprises a principal driving shaft 1 supported by a fixed frame, which is caused to rotate through known means by an independent motion source, or through the interposition of driven means.
  • the lever 12 extends upwards, and its upper end is attached to a link 15 pivoted, at its other end to a fixed transverse axle 16 restrained at its end by a pair of rod-like elements, 17 and 18, which are in parallel and in side by side arrangement, axially sliding in synchronism i.e. perpendicularly to the driving shaft 1, as will be better appreciated further.

  • two chambers 28 and 29 are thus defined, of a section corresponding to the cross section of the packets of cigarettes to be transferred.
  • the element 21 is attached to the rods .17 and 18, by the support feet 22, whereby it is subjected, in rigid connection relationship with said rod-like members 17 and 18, to a reciprocal movement.
  • the arrangement of the member 21 is such that the chambers 28 and 29 are positioned in alignment, alternately during its movement, with a canal 30 along which the advance of the packets P of cigarettes occurs, which packets are arranged in file coming from the line of packing and glueing of the packets themselves. Therefore said chambers 28 and 29 are arranged so as to alternately constitute the extension of the pipe 30.
  • the transverse end section of the chambers 28 and 29, opposite the insertion section adjacent to the pipe 30, is provided with a stopping Wall 31 for the introduced packets P.
  • the drum cam 7 controls the push-and-lift members capable of expelling the packets of cigarettes alternately from the chambers 28 and 29.

  • the arms of the fork 46 are aligned with the slit 27 of the chamber 29 when the chamber 28 is aligned with the pipe 30. In such a position, the fork 46 may penetrate crosswise in said chamber 29, throughout its length.
  • the drum cam 8 is provided with a peripheral groove 46 of unsymmetrical course.
  • a first idle roller 48 is engaged, whose shaft of rotation is supported by a bell-crank lever, 49, which, since it is pivoted on the shaft 50 running from the fixed case, is provided at its free end with a cubical projection 51.
  • an arm 52 is secured, which is attached, near the shaft 50 and extends upwards; said shaft supports, on the upper side, a plate 53 which extends horizontally, cantilever-wise.
  • lever 49 With the said lever 49 cooperates a small bell-crank lever 54 pivoted in 55 and provided externally with an aperture 56 of size corresponding to that of the projection 51, so that the latter may be associated slidingly.
  • the same lever 54 is moreover provided at its other end with a horizontal plate 57 which extends canterlever-wise, symmetrically confronting the plate 53.
  • the plates 53 and 57 are situated in the region of the aperture of the chamber 29 when the chamber 28 is in alignment with the pipe 30. Consequently in such a situation the plates 53 and 57 constitute a closing surface above said chamber 29.
  • the box element 21 performs a reciprocal movement which brings once the chamber 28 and once the chamber 29 into alignment with the guiding pipe 30 of the packets P of cigarettes. That is to say reciprocal movements of the member 21 cover a space corresponding to about the width of three packets of cigarettes.
  • the chamber 28 When the chamber 29 in side-by-side arrangement comes into alignment with the introduction pipe of the cigarettes 30 the chamber 28 is carried in correspondence to the base of the loading and drying column shown in its entirety by reference numeral 58. When on the contrary it is the chamber 28 which is aligned with the pipe 30, the chamber 29 is carried in the range of the base of a second loading column 58a parallel to the first (see FIGS. 3 and 6). Because said columns 58 and 58a have a section substantially corresponding to the larger longitudinal section of the packet it results that said colums 58 and 58a are interspaced by a distance approximately of the width of a packet.
  • the drying column 58 is defined by a pair of fixed walls 59 and 60 and by a pair of walls 61 and 62 perpendicular to the previously mentioned walls and thus parallel between each other.
  • the internal cross section of the column approximately corresponds to the larger of the sections of the packet of cigarettes.
  • the column is therefore in a position to receive the packets lying on their larger side and superimposed.
  • the wall 61 is defined by an access door, which may be spring opened by means of a handle 63 the wall 62 is instead attached in its upper section 62, while it may be oscillated in its lower section about a horizontal pivoting shaft 64.
  • the development in height of the column is in relation to the problem which will be hereinafter discussed.
  • the second drying column 58a parallel to the column 58, is achieved in a fashion exactly analogous to the latter one whereby the corresponding parts are indicated by the same reference numerals, with the addition of the letter a.
  • a shaft 65 On it is keyed a chain wheel 66, which is caused to rotate by a prime motion source, not shown, which source may be in relationship with the same main shaft of the conditioning machine, or be independent.
  • this chain wheel 66 receives the movement through the transmission chain 67 and the gear wheel 68, from a chain wheel not visible in the figure and rigidly mounted on shaft 69 on which is also keyed the chain wheel 70 which receives the movement from said primary motion source.
  • Said shaft -65 carries, at an end, a chain wheel 71. Furhermore on the shaft 65 in the range of the area included between the two columns, two angular grooves are machined out, determining corresponding parts 72 and 73 which are excentric with respect to the shaft, and out of alignment between each other. Therefore the shaft 65 is in fact a cam shaft, in which the cams are formed by the shafts 72 and 73.
  • a lever 74 On the portion or cam 73 engages the groove formed by the fork shaped end of a lever 74. This is pivoted on a shaft 75 revolvingly carried by the fixed structure and on which a lever or arm 76 is carried. At the free end of said arm 76 is pivoted in 77 a portion or lever 78, which is substantially horizontal and whose free end is shaped .to a hook 79. This latter connects to a bridge member 80 attached to the wall 62.
  • the lever 78 is under the action of an elastic spring '81, an end of which is secured in 82 to said lever 78 and whose second end is attached in 83 to the fixed structure of the machine.
  • the wall 62 of the column 58 is caused to oscillate about the shaft 64.
  • a further bell-crank lever 74a cooperates in an exactly analogous manner with the cam 72 of the shaft 65.
  • the chain wheel 89 actuates, through a chain 90, a chain wheel 91, with the aid of the two idle wheels 92 and 93.
  • a cog wheel 95 revolves in rigid connection with its own shaft 94. Said wheel 95 engages with a second cog wheel 96, revolving in rigid relationship with its own shaft 97.
  • the shaft 94 is supported by a plate-like member 98 which similarly supports the shaft 99 of a further cog wheel 100 kept in permanent engagement with the wheel 95.
  • the aforesaid plate-like member 98 is attached to a pin 101 revolving in the fixed framework or structure of the apparatus and carrying, attached thereto, a plate .102 provided underneath with a slot 103 inside which engaged a locking screw 104, which may be screwed into fixed framework.
  • the actuation and the direction of rotation of the wheel 96, as well as all the members connected to it, which will be further described, which generally occurs directly by means of the wheel 95, can easily be reserved by slackening the screw 104 and causing the plate 98 to rotate about its own shaft 101.
  • the engagement between the wheels 95 and 96 comes to an end, said wheels being spaced apart between each other, while the wheel 96 meshes with the wheel 100, which receives the movement from said wheel 95, with which it is always in mesh.
  • a plurality of synchronization cams 105 capable of operating each on the actuation member of a corresponding microswitch 106 and a further chain wheel 107, which, by means of a chain 108, causes an overhanging chain wheel 109 to rotate, said chain wheel being supported by a shaft 110 which is in rigidly connection with it.

  • the said section is attached in 125 to a revolving shaft .126 supported in 127 by lateral feet 59 and 60 of the column 58.
  • a radial arm 128 is secured which is locked by means of a link 129 to the movable element 130 of an electromagnet 131.
  • the plane 124 is kept in line with the plane 123 by means of the action of a return spring 132, which is attached at an end, in 133, to the fixed framework of the machine and is connected at the other end, in 134, to a further radial arm likewise attached to the rotatable shaft 126.
  • the excitation or energization of the electromagnet 131 is brought about by a pulse from a memorizer which is activated, as will be explained hereinafter, by a pairs of metal sensing members like those referred to by reference numerals 137 and 138, which are inserted in series in an electrical circuit or alternatively also, if conveniently positioned, said memorizer may be activated directly by such metal sensing members or sensors.
  • Said sensors 137 and 138 are pivoted in 139 and 140 respectively and are subjected to the action of pressure springs 141 and 142 respectively.
  • a second pair of sensing members 143 and 144 maintained inspring-biased engagement against the surfaces of the packets by the action of the springs 145 and 146, act in similar manner, said second pair also acting upon the excitation of the electromagnet 131.
  • the packets of cigarettes coming from the conditioning line are still wet in the area in which the glueing of the envelope has been effected. Since it is necessary to leave the glueing material to dry before dispatching the packets of cigarettes to successive work stations in the apparatus according to the invention at least one column has been provided and in the represented embodiment two such columns have been provided in which the packets of cigarettes are inserted from the bottom. As the packets reach the columns, they are introduced the bottom underneath the packets previously housed in them and the arrival of new packets determines the progressive rising of the pile of superimposed packets.
  • the chamber itself is put in communication with the base of the overhanging column 58.
  • the arms of the fork 43 are inserted in the slit 26 of the chamber 28 and they push from the bottom to the top the packet which is in such chamber all the pile of superimposed packets previously inserted into the column 58 acting on said packet. Therefore the fork 43 raises the packet in correspondence to the inside of the column, there forming the base of the packets already present.
  • the time taken by the packets to arrive from the base to the top of the column is, as has been said, in relation to the time necessary for the natural drying of the glueing materials.
  • the packets Before arriving at the top of the respective columns, the packets pass in near two sensitive members.
  • the first of them formed of the pair of plate or blade members 137 and 138 (or 137a and 138a respectively), is designed to indicate the passage of a defective packet, or more exactly a packet without said stamp or label or sealing tape.
  • the upper edge of the packet corresponding to the area in which normally the aperture for the removal of the cigarettes is effected, is made of tin foil. This edge is sealed by a stamp or small label, sealing or tape piece. But it might happen, for any reason, that the sealing tape would not be applied to one or more packets.
  • the packet has said upper edge facing the pair of elements 137 and 138 (137a and 138a) these are disposed in manner such as to maintain contact with the said base exactly in correspondence with the sealing tape. It is remembered also that the said elements are inserted in series in an electrical circuit including directly the electromagnet 131 or the said memorizer. The circuit however is normally opened and closed when a contact is established between said elements 137 and 138 (137a and 138a). Therefore when the sealing tape is there, since it is made of paper material, it acts as an insulator between said blades 137 and 138 (137a and 138a). However if a packet of cigarettes without sealing tapes arrives in the sensing position, the members 137 and 138 (137a and 138a) graze directly against the tin foil which being a moderate conductor, will close the connection between said members themselves.
  • electromagnet 131 will directly activate the electromagnet 131 or will sensitize the memorizer which, when the packet of cigarettes arrives in correspondence with the tiltable plane 124 (124a), it will excite or activate said electromagnet 131 (131a) which, by attracting the movable element 130 (130a) will determine the tilting of the same plane 124 (124a) and the consequent removal of the packet without said stamp of sealing tape.
  • senser pairs 143 and 144 operate which are however designed to sense the possible lack of the label above the first tin foil envelope of the passing packets. Also in this case the defective packet would be removed through the tiltable plane 124 (124a).
  • the packets which arrive in succession, in step, at the ends of the columns, and therefore with their bottom edges aligned to the guide plane 123 (123a) are put in movement by pushing arms 120 (121) which move continuously in rigid connectionwith the chain 16 (17), are spaced from the column, and guided towards possible successive processing stations.
