  • the invention further relates to a device for testing cigarettes for cigarette packaging or manufacturing machines with at least one axially displaceable plunger, which has a head for immersion in a Has cigarette end.
  • Methods and devices for checking cigarette ends are known arranged in three layers, the geometry of a cigarette formation corresponding plungers that are used to check a cigarette formation be brought up. With correct training the cigarettes will be at all tappets in a rear position. However, is missing a cigarette or if a cigarette is only loosely filled, the plunger remains in its Starting position or is only slightly depressed.
  • GB 2 196 311 describes a method and an apparatus for testing Cigarettes known by means of movably mounted tappets, the position of the Ram is detected by means of inductive sensors. To do a flawless Enabling evaluation of the individual plunger positions is a considerable one Distance between the sensors and a significant material accumulation on Tappet head to ensure a sufficient change in the magnetic field required.

  • the plunger depending on the position of the plunger an electrical, magnetic or associated with a sensor influenced electromagnetic field, whereby one of the influences Ram position corresponding signal is generated.
  • the plunger has an area for influencing a electrical, magnetic or associated with a sensor electromagnetic field, the sensor being designed such that it generates a signal corresponding to the plunger position based on the influence.
  • test method according to the invention or the test device according to the invention is no longer susceptible to dust, since it is not based on an optical principle.
  • the position of the plunger is preferred based on a penetration depth of a ferround / or ferrimagnetic area of the plunger into the interior of the sensor forming, in particular annular, coil determined.
  • the coil electrically connected to a measuring device which generates a signal depending on the the plunger position representing penetration depth of the ferro and / or releases ferrimagnetic range in the coil.
  • the position of the plunger is preferred based on the flow of a Hall element forming the sensor from one of a magnetic area of the plunger generated magnetic field, the Hall element at two opposite sides with an electrical voltage and that Signal depending on the plunger position flowing through the Hall element representing magnetic field is generated.
  • the Hall element preferably with an electrical Connected measuring device that a signal depending on the flooding the Hall element, representing the plunger position Magnetic field emits.
  • the advantage of these preferred solutions is that their Size is small enough to accommodate a larger cigarette formation to be able to scan at the same time. Thanks to the invention must now the testing of cigarettes is no longer staggered be performed.
  • the devices according to the invention can namely be realized so small that the required Measuring devices, namely Hall elements or coils no larger than the thickness of a cigarette. In particular the coils therefore have an outer diameter that is smaller than a cigarette diameter.
  • the plungers are preferably queried individually. This is everyone Ram a single element to be queried, namely a Hall element or a ring-shaped coil in particular.
  • the signals emitted by these elements are transmitted by means of a Evaluation unit evaluated. Due to the small design, it can already this evaluation unit housed in the housing of the test device be, so that advantageously a complex Wiring of all individual elements to a central machine control can be omitted.
  • FIG. 1 shows a cigarette packaging machine 10 with a Cigarette magazine 11, in which there are cigarettes 12, the downwards during the ongoing packaging process Move in the direction of arrow 13 shown in FIG. 2.
  • the Magazine 11 opens into several, namely four, shown in Fig. 2 Shaft groups 14, each consisting of a plurality, namely seven, shafts 15 exist.
  • any cigarette formation 16 consists of three layers, the outer layers each consist of seven and the inner layer of six cigarettes. However, there are other formations with another Number of layers and / or cigarettes per layer possible.
  • On rotating cigarette turret 17 transports the cigarette formations 16 for the further packaging process. While the rotation of the formations 16 are in the turret 17 the cigarettes are at rest relative to each other. Therefore, the cigarette revolver is preferably suitable for carrying out a cigarette check, especially the completeness check of cigarette formations.
  • Fig. 1 are to the right and left of Cigarette turret 17 four testers 18. These testers 18 are on both sides of the cigarette revolver 17 arranged that two devices for checking the filter-side cigarette ends and two other devices 18 serve to check the tobacco-side cigarette ends.
  • the Test devices 18 are in one in the longitudinal direction of the cigarette slidable housing 19 housed. The respective housing 19 are shown in the direction of FIGS. 1, 3 and 5 Double arrow 20 is displaceable by means of a not shown Adjustment. To perform a test the adjusting device moves a test device 18 in the direction of a cigarette formation 16 to follow one perform the test procedure described in more detail.
  • a conveyor 21 leads through the cigarette turret 17 the formations 16 in the direction of arrows 22 in the direction an assembly 23 for wrapping the formations in tinfoil paper.
  • Stanniolbobinen 24 store the web-wound Tinfoil paper and give it in the direction of arrows 25, namely in the direction of the assembly 23.
  • the tin foil passes an embossing device 26.
  • the assembly 23 also serves to cut the tin foil in Cuts that are wrapped around cigarette formations.
  • Kragenbobinen 27 stock material webs for collars to be cut, which are covered with tin foil Cigarette formations 16 are placed.
  • FIG. 2 shows a section along the line II-II according to FIG. 1 by the packaging machine 10 for a more detailed illustration the arrangement of the testers 18.
  • Two pulled out Test devices 18 shown are on the front of the cigarette revolver 17 and are on a common Carrier 28 mounted.
  • Two further test devices 18 are located themselves on the back of the cigarette revolver 17 and are dashed shown. Also these test devices on the back 18 are on a common carrier (not shown) assembled.
  • the test devices 18 are each via connections 29 and connection cable 30 with a machine control, not shown connected.
  • FIG. 3 and 4 show a test device with annular coils 32, which have a cavity 33 on the inside.
  • Cavity 33 can be a ferromagnetic or ferrimagnetic region 34 of a plunger 35 (in the manner of a coil core).
  • the plunger 35 is axially displaceable in the housing 19 stored against a spring force. This causes one on an inner wall of the housing 36 supported spring 37 that the plunger 35 from the housing is pushed out until a stop 38, against which the spring 37 presses, a housing outer wall 39 reached.
  • the housing is used to carry out a test 19 together with plunger 35 and coils 32 in the direction of to be tested Cigarettes 40, 41, 42 moved.
  • the second position is generally characterized in that the ferro / ferrimagnetic area does not completely cover the inside of the coil achieved, for example, even if the ferromagnetic / ferrimagnetic Area 34 the coil interior or the cavity 33 only partially completed.
  • the coil 32 By penetration of the ferro / ferrimagnetic area 34 of the plunger 35 in the cavity 34 of the coil 32 becomes the inductance the coil 32 changed.
  • This change can be measured to capture.
  • the coil to do this with alternating current or alternating voltage.
  • the electrical behavior of the coil changes.
  • the change in impedance can also be obtained by determining a changed resonance frequency one from this coil and a capacitor formed resonant circuit, or if the Vibration of the resonant circuit breaks off.
  • the coil is supplied with DC voltage or applied to direct current.
  • the insertion of the ferro- / ferrimagnetic Area then also leads to a change in inductance. This changes with a constant coil current the energy content of the coil.
  • Such changes can be recorded by measurement, so that information about the plunger movement and thus the depth of penetration of the plunger can be placed in the cigarette end.
  • the plunger 35 is mounted such that the Ferro- and / or ferrimagnetic region 34 of the plunger 35 concentrically can penetrate into the inside of the coil 32.
  • the sensor having the coils 32 so small to make it smaller than a about 5.3 to 7.9 mm is the cigarette diameter.
  • the coils 32 are also arranged at a distance corresponding to this diameter. Therefore, the coils 32 have a smaller outer diameter than the cigarette diameter, preferably maximum 5 mm.
  • the plungers 35 then preferably have one maximum outer diameter of about 2 mm.
  • the structure described has the advantage that all coils or sensors can be accommodated within the housing 19. Due to the space-saving design, it can also be used inside of the housing 19, which may have a microprocessor Evaluation device are housed, the evaluation board 46 along with electrical and electronic components 47 having. This makes it possible to close the evaluation device to accommodate the actual sensors or coils, so that elaborate wiring of all sensors with one removed lying evaluation unit, e.g. the machine control can be omitted.
  • the connection to the machine control 29 must therefore only a few lines, but not one of the number of Sensors have a corresponding number of lines. Thereby the packaging machine is less prone to failure overall and moreover, it can be manufactured more cost-effectively.
  • the coils 32 are in a carrier element connected to the housing 19 48 arranged, the holes for receiving the annular Coils 32 and bores arranged concentrically thereto for receiving the plunger 35.
  • the carrier element 48 also serves the mechanical stability of the arrangement of the coils 32.
  • the circuit board 49 is connected to the evaluation circuit board via a plug connection 50 46 connected.
  • the circuit board 49 has bores 51, which are opposite the plungers 35 and damage to the Board 49 if the plunger 35 is pressed too deeply into the interior avoid the housing 19.
  • FIGS. 5 and 6 Another test device 18 is shown in FIGS. 5 and 6.
  • This test device 18 differs from that 3 and 4 in that instead of Ferro / ferrimagnetic areas on the tappets on each tappet there is a magnetic area 52.
  • This magnetic Area 52 is a bar magnet that creates a constant magnetic field. But it is also a magnetic field generating coils possible.
  • By moving one Tappet can now use this magnetic field in a first, namely for the two lower plungers 35 apply a Hall element 53 flood. In a second position, it floods Magnetic field, however, not the Hall element 53 or only less. This second position corresponds to that in FIG. 5 for the upper one Tappet 35 position shown.
  • Hall element 53 is on two opposite sides with an electrical Reference voltage or current source connected.
  • the magnetic field lines passing perpendicularly through the Hall element are carriers perpendicular to their through the Direction of movement due to reference source distracted. Thereby arises at two offset from the connections of the reference source sides of the Hall element called a Hall voltage Potential difference.
  • This Hall voltage is measured using a electrical measuring device measured. This tension becomes a signal depending on the flowing through the Hall element 53, generated magnetic field representing the plunger position.
  • the measuring device for determining the plunger position with Hall element 53 and magnetic plunger area 52 allow one small design of the device, so that here too the required Electronics can be accommodated within the housing 19 is. Therefore, an evaluation board is also in this test device 46 for receiving electrical or electronic components 47, in particular a microprocessor for evaluation of the sensor signals or signals of the Hall elements 53, inside of the housing 19 is provided.
  • the evaluation board 46 is a Plug connection 50 connected to a circuit board 55.
  • This Board 55 has the Hall elements 53, which are in the range of Bores 56 are arranged. These holes 56 are opposite the plungers 35 are arranged and serve to carry out the magnetic Areas 52 of the plunger 35.
  • the electrical connection the Hall elements 53 with the evaluation board 46 takes place via printed conductors arranged on the board 55 and via the Plug connection 50.
  • a support element connected to the housing 19 57 serves to hold this board 55.
  • Both test devices 18 according to FIGS. 3 and 4 or according to FIG. 5 and 6 are via a connecting element 55 with an adjusting device for moving the test device 18 together with the plunger 35 connected to the cigarettes to perform a test.
  • This adjustment device is mechanical, electrical, pneumatically and / or hydraulically operated.
  • the evaluation unit either already attached to each test device or the machine control system uses the signals supplied by the coils or Hall elements data about possible malfunctions. Because with every test preferably an entire cigarette formation is scanned, For example, three adjacent, Coils or Hall elements that indicate an error indicate a blocked cigarette holder. Based on the signals generated by the evaluation unit or machine control an alarm or error signal can be generated or else a control signal to stop the machine or to change it certain machine parameters such as machine speed. Furthermore, a control signal for ejecting a faulty cigarette formation, one Ejector causes the faulty cigarette formation to sort out the packaging process.
  • the reduced size of the individual Ram-scanning measuring devices a compact test device, which are not susceptible to interference due to the lack of optical components against dust.
  • the invention also allows an evaluation via the operating data acquisition, so that statements about the filling of individual cigarette position possible are. This allows possible unreliability individual cigarette chutes in the cigarette magazine to recognize.
  • the cigarette check or head check is advantageously already with one housed in the test device Microprocessor performed so that an evaluation the sensor signals is already possible in the test device.
  • the devices explained also have the advantage that a Cleaning of the mechanical components without removing the complete Device and electronic components is possible there (not shown) side cover for cleaning can be removed with a compressed air gun, for example. Furthermore, the arrangement described has the advantage that a Tappet 35 pushed in too far does not cause the coils 32 or Hall element 53 and the associated circuit boards 49, 55 can, as is the case with other arrangements with axial arranged initiators or proximity switches occur can. Overall, the invention therefore enables an essential one Improve cigarette testing.
