  • This invention relates to the technical sector of machines for the tobacco industry.
  • this invention relates to an inspection unit and method for quality control of disposable cartridges for electronic cigarettes. It should be noticed that the term“quality control” refers to a check of the“quality” of the cartridges.
  • the technical purpose which forms the basis of this invention is to propose an inspection unit and method for quality control of disposable cartridges for electronic cigarettes which overcome the above- mentioned disadvantages of the prior art.
  • the aim of this invention is to provide an inspection unit and method for quality control of disposable cartridges for electronic cigarettes which can guarantee correct and efficient qualitative assessment of the entire product during processing.
  • the quality control guarantees an assessment of the quality of the whole product.
  • This invention shows an inspection unit for quality control of disposable cartridges for electronic cigarettes, which comprises an advancement conveyor and an electromagnetic detector.
  • the advancement conveyor has a portion having a succession of retaining seats configured to receive respective cartridges from a feed unit for feeding the cartridges.
  • the electromagnetic detector is configured to detect one or more properties of the cartridges so as to determine whether they conform to one or more acceptability criteria and comprises a transmission shell configured to transmit an electromagnetic signal and a receiving shell configured to receive said electromagnetic signal. Those shells are facing one another, defining a detecting chamber configured to slidingly receive therein the portion of the advancement conveyor and at least a cartridge housed in a respective retaining seat, wherein the cartridge is positioned completely inside the detecting chamber.
  • the particular structure of the unit according to this invention allows a precise measurement to be taken of the properties of the cartridges in an extremely effective and efficient way by means of an overall assessment of the whole cartridge which is sliding inside the detecting chamber, since the detecting signal is at its maximum at the chamber, specifically at a central portion of the chamber.
  • the fact that the detection occurs in a chamber delimited by the two above-mentioned shells guarantees isolation from everything that is not important for the detection, but which, in fact, could otherwise become a factor interfering with the detection.
  • This invention also relates to an inspection method for quality control of disposable cartridges for electronic cigarettes which comprises the steps of:
  • That procedure guarantees a correct assessment of the structural integrity and the quality level of the product during processing, so as to guarantee its conformity to one of the predefined quality parameters which define its suitability for marketing.
  • FIG. 1 A shows a perspective view of an inspection unit for quality control of disposable cartridges for electronic cigarettes
  • Figure 1 B shows a further perspective view of the unit of Figure 1 ;
  • FIG. 3 shows a perspective view of an electromagnetic detector according to this invention.
  • each cartridge C comprises a case, for example made of plastic material, which has a tubular shape, has a bottom wall and is closed at an upper end (that is to say, opposite to the bottom wall) by a sealing ring which is sealed to the case.
  • the case may contain a quantity of powdered tobacco topped by a pad made of filtering material and, preferably the bottom wall is micro- perforated.
  • the case may also contain a liquid suitable for being vaporised in an electronic cigarette and, if so, the bottom wall does not have holes in it.
  • the unit 1 comprises an advancement conveyor 2 which has a portion 3 having a succession of retaining seats 4 configured to receive respective cartridges C from a feed unit for feeding the cartridges C.
  • the advancement conveyor 2 is configured to accept a succession of cartridges C for electronic cigarettes arriving from a processing station located upstream of the inspection unit and to receive them in respective retaining seats 4 each of which is suitable for housing and retaining one cartridge C during the movement of the advancement conveyor 2.
  • the portion 3 has a curved saw-toothed profile adapted to guide the gradual insertion of the cartridges C into the retaining seats 4, in particular the retaining seats being defined by the bases of the curved teeth.
  • a cartridge C arriving from a suitable feed unit encounters the advancement conveyor 2, it makes contact with the curved surface of the tip of a tooth of the profile of the portion 3, the gradual advancing of the advancement conveyor generates sliding of the cartridge C along the back of the same tooth until the cartridge reaches the base of the tooth and is stably housed in the retaining seat 4 defined by that base.
  • the retaining seats 4 are configured to retain respective cartridges C in a substantially vertical position and the portion 3 has a horizontal surface surrounding the succession of retaining seats 4 which is adapted to restingly receive an undercut of an external surface of the cartridges C.
  • the advancement conveyor 2 comprises an advancement drum having a vertical axis X of rotation, and wherein the succession of seats 4 has a main extension direction that is substantially parallel to the axis X of rotation of the drum.
  • the succession of seats 4 is arranged at an edge of the advancement drum, in other words, the portion 3 is a peripheral portion of it.

  • the succession of seats 4 may also be arranged at an edge of the belt, similarly to the position in the advancement drum 2, and therefore the portion 3 may be a peripheral portion.
  • the portion 3 may also be arranged at an inner band of the belt, in other words, the portion 3 may be a central portion.
  • the unit 1 additionally comprises an electromagnetic detector 5, configured to perform an inspection on each cartridge C, that is to say, to detect one or more properties of the cartridges C so as to determine whether it satisfies one or more acceptability criteria.
  • the term“inspection” means a check of the status of the cartridges by passing through the whole article a radiation generated by a suitable electromagnetic detector which, by way of example and without limiting the scope of the invention, may be of the capacitive, inductive, microwave or X-ray type.
  • That process allows an assessment as to whether the cartridge C inspected can be used for making a marketable product or whether the cartridge C has defects or imperfections which are such that they make it unsuitable for use for making a product of the tobacco industry which can meet predetermined quality standards.
  • the electromagnetic detector 5 in turn comprises a transmission shell 6 and a receiving shell 7 respectively configured to transmit and to receive an electromagnetic signal.
  • Those shells 6, 7 are facing one another in such a way as to define a detecting chamber 8 configured to slidingly receive therein the portion of the advancement conveyor 2 and at least a cartridge C housed in a respective retaining seat 4.
  • a succession of cartridges C sequentially passes through the detecting chamber 8 and is inspected by the action of the electromagnetic detector 5 when positioned completely inside the chamber, preferably in a central part 8a of it.
  • the electromagnetic detector 5 has substantially a U-shape (or a C-shape) adapted to at least partly house the advancement conveyor 2 in such a way that the portion 3 is partly surrounded by the electromagnetic detector 5.
  • the electromagnetic detector 5 is configured to be associated with the advancement conveyor 2 so that it contains the portion 3 which therefore slides between the transmission shell 6 and the receiving shell 7.
  • the inspection unit guarantees an optimum product quality inspection process, since, by receiving inside it both the portion 3 and the whole cartridge C, the cartridge C is inspected as a whole when it is located at the point of maximum intensity and focus of the detecting signal, that is to say, the electromagnetic signal generated by the transmission antenna and received by the receiving antenna.
  • the transmission shell 6 has an inner transmission cavity 6a and a transmission antenna, which is arranged inside the transmission cavity 6a
  • the receiving shell 7 has an inner receiving cavity 7a and a receiving antenna, which is arranged inside the receiving cavity 7a.
  • the shells 6, 7 overall have a substantially parallelepiped conformation and are positioned one on top of the other in such a way that the respective transmission cavity and receiving cavity are facing one another and adjacent, thereby defining the detecting chamber 8.
  • the transmission shell 6 and the receiving shell 7 also comprise respective dielectric sheaths 6b, 7b, arranged so as to at least partly cover the respective surfaces of the shells 6, 7 arranged facing one another.
  • Those dielectric sheaths 6b, 7b are facing towards the portion 3 of the advancement conveyor 2 to define the detecting chamber 8 and they have a first end, distal relative to the advancement conveyor 2, where they are in contact with each other, and a second end, proximal to the advancement conveyor 2, where they spread apart, thereby defining the zone of the detecting chamber 8 inside which the portion 3 of the advancement conveyor 2 and the respective cartridges C retained in the retaining seats 4 of the portion 3 can slidingly pass through.
  • the detecting chamber 8 comprises a first part, that is to say, the central part 8a, which is configured to receive the cartridges C to be inspected and is arranged at a central zone 8a of the electromagnetic detector 5, preferably at a geometric centre of it, and a peripheral part 8b, which extends starting from the central part 8a and is configured to receive the portion 3.
  • the central part 8a and the peripheral part 8b are delimited by the second end of the dielectric sheaths 6b, 7b.
  • central part 8a refers in particular to a portion of the detecting chamber 8 surrounding the geometric centre of the electromagnetic detector.
  • the dielectric sheaths 6b, 7b allow a considerable improvement in the efficiency and effectiveness of the inspection unit 1 , since on one hand they provide a protective barrier which prevents access by unwanted external agents, for example dust, into the detecting chamber 8 defining a passageway suitable for the sliding passage of only the portion 3 and the cartridges C, and on the other hand they allow optimisation of the measuring process, promoting a concentration and homogenisation of the radiation transmitted by the transmission antenna inside the detecting chamber 8, also optimising its reception by the receiving antenna.
  • the passage of the portion 3 of the advancement conveyor 2 inside the detecting chamber 8 renders necessary suitable devices which ensure that said component does not interference with the inspection process and, therefore, the portion 3 of the advancement conveyor 2 is made of polymeric material, preferably the whole advancement conveyor 2 is made of polymeric material.
  • polymeric material refers in particular to a material which has characteristics such that it does not generate any kind of interference, distortion, disturbance of electromagnetic signals generatable by the transmission antenna for performing an inspection of the properties of the cartridges C.
  • the electromagnetic detector 5 is a microwave detector, preferably operating at a wavelength of between 10 9 and 10 12 Hz, usable for measuring the density and/or the moisture of a filling product of the tobacco industry contained inside the cartridges C.
  • the detecting chamber 8 is a resonance chamber.
  • the microwave detector is configured to produce, through the transmission antenna, an electromagnetic field with a precise geometry, defined by field lines which depend on the construction characteristics of the detector, and to emit the detecting signal.
  • the detecting signal produced then passes through the cartridge C and arrives at the receiving antenna, which in turn is connected to a processor able to receive it and analyse it in such a way as to obtain, as a function of the disturbance to which the signal was subjected as it passed through the cartridge C, information about the density and/or moisture of the filling product.
  • That information may be further processed using known techniques for obtaining a weight of the filling product, in particular making it possible to determine whether, in the production steps upstream of the inspection unit 1 , the correct quantity of filling product has been inserted into the cartridge C.
  • the presence of the dielectric sheaths 6b, 7b is particularly useful and effective, since they guarantee that the field lines of the electromagnetic field are optimally focused on the central part 8a of the detecting chamber 8, in this specific case a resonance chamber, that is to say, the part in which the cartridge C is positioned at the moment of the inspection.
  • the electromagnetic detector is a detector of the capacitive type.
  • the transmission shell and the receiving shell define the plates of a capacitor inside which the cartridges C slide.
  • the different dielectric constant of the filling product compared with that of the air generates a measurable variation of the capacitance of the capacitive detector.
  • That variation is directly linked to the degree of moisture of the filling product and once this value has been obtained, it is possible, as already indicated, to convert it using known terms into weight information, indicating the quantity of filling product contained in the cartridge C.
  • the inspection unit 1 also comprises removal means 9, arranged downstream of the electromagnetic detector 5, with respect to the advancement direction of the advancement conveyor 2, configured to extract, from the retaining seats, non-compliant cartridges C detected by the electromagnetic detector 5.
  • the removal means 9 are configured to allow the performing of a rejecting procedure intended to remove from the production process all cartridges C which do not satisfy the predefined quality parameters.
  • the removal means 9 may be made using suction tubes arranged above the advancement conveyor 2 and therefore set up to suck the non-compliant cartridges C, lifting them out of the respective retaining seats 4 until they are completely extracted from the seats.
  • This invention also relates to an inspection method for quality control of disposable cartridges for electronic cigarettes.
  • the method disclosed comprises arranging an inspection unit 1 made as indicated above.
  • a detecting step is performed, by means of the electromagnetic detector 5, for detecting at least a property of a cartridge C positioned completely inside the detecting chamber 8.
  • the electromagnetic detector 5 inspects each cartridge C passing through the detecting chamber 8, when the cartridge is completely inside it, preferably in a central part 8a of it.
  • central part 8a refers to a portion of the detecting chamber 8 surrounding the geometric centre of the electromagnetic detector 5.
  • the cartridges C come out of the detecting chamber 8 and the succession of cartridges C can be released to receiving means for receiving the cartridges C.
  • Those receiving means arranged downstream of the inspection unit will allow the cartridges C to be moved on to subsequent further processing steps intended to obtain a finished product of the tobacco sector.
  • the advancement conveyor 2 may be moved continuously, that is to say, the advancement conveyor 2 receives the cartridges C and makes them slide through the detecting chamber 8 in a continuous flow in which the inspection is performed when a cartridge C is completely inserted inside the detecting chamber 8.
  • the advancement conveyor 2 may be moved intermittently, that is to say, with a fixed step, preferably equal to the distance existing between two adjacent retaining seats 4, the advancement conveyor 2 receiving the cartridges C and making them slide through the detecting chamber 8 in an intermittent flow, that is to say, the cartridge C remains stationary inside the detecting chamber 8 for the time necessary to complete the inspection procedure.
  • the method according to this invention comprises, before the detecting step, a step intended to calibrate the electromagnetic detector 5 by means of a detection of each retaining seat 4.
  • That step allows systematic consideration and assessment of the contribution to the measurement caused by the fact that part of the portion 3, the part with the retaining seats 4, enters the detecting chamber 8, thereby guaranteeing correct inspection, during the subsequent measuring step, of the cartridges C.
  • the electromagnetic detector 5 substantially takes a measurement of only the portion 3 of the advancement conveyor 2, limited to the part which enters the detecting chamber 8, in the absence of cartridges C.
  • the detecting step comprises sub-steps intended to allow operators to define whether or not a predetermined cartridge C can be correctly used for making a finished product.
  • the detecting step comprises a first sub-step intended to determine if the at least a property measured satisfies a predefined acceptability criterion and, if that acceptability criterion is not respected, a second sub-step intended to activate a rejecting procedure for rejecting the cartridge C, in such a way that it is removed from the production process.
  • this invention achieves the proposed aims, overcoming the disadvantages of the prior art and making available to the user an inspection unit and method for quality control of disposable cartridges for electronic cigarettes which guarantee the performance of a correct and efficient qualitative analysis of the processed product.
