Definitions
- the invention relates to a method and a device for checking the content a particularly closed package according to the generic term of the independent Expectations.
- the individual items point at least in Essentially the same dimensions, i.e. the dimensions of the objects are not identical, but they are correct in the area of usual manufacturing tolerances match. So that the individual items such. B. side by side (in rows) or in several rows one above the other (layers).
- they are a package, especially in the form of a Outer casing, e.g. made of thin cardboard or the like, with a large area Front and rear walls as well as side and end walls combined in one package.
- An example of the items mentioned are cigarette packs, which in a manner known per se for delivery in larger quantities in the form of Container packs to be put together so-called cigarette sticks.
- the invention is accordingly based on the object, a simple and safe Method for checking the content of a package, in particular a closed package, e.g. e.g. a pack of cigarettes.
- the invention provides that the package at least in one area of a test wall for radiation and for the reception of electromagnetic penetrating the respective test wall Waves, especially electromagnetic waves in the microwave range, provided sensor with regard to the presence of a Subject is examined.
- the device is accordingly distinguished according to the invention through one to emit and receive electromagnetic Waves provided sensor arranged and aligned in this way is that emitted electromagnetic waves are an area of a test wall of the pack and at least partially penetrate and from the pack reflected or penetrating electromagnetic packets from the Sensor are detectable.
- the test wall is the respective one front, back, side or end wall of the pack facing the sensor.
- the sensor enables a completely contactless check of the package. This will damage the packaging and the individual items, so z. B. the cigarette packs avoided.
- the check according to the invention by means of electromagnetic waves is also not - such as weighing processes - disadvantageously due to fluctuations in moisture or the like affected.
- the electromagnetic emitted by the sensor and penetrating into the package Shafts are used in such a way that the decision regarding the Presence of an object in the area of the incident waves the reflection or absorption characteristics of this area is evaluated.
- An object existing in the respective area results from the evaluation the reflection characteristics increased reflection and thus a corresponding increased signal at the sensor.
- the absorption characteristics there is an increased absorption and thus a correspondingly reduced Signal at the sensor.
- the reflection or absorption is omitted that a correspondingly reduced or increased signal is set at the sensor.
- Such a systematic Check passes e.g. in that a section of the test wall of the pack is checked.
- the "section” is accordingly one in comparison to the "Area” understood larger region, e.g. a region with and between you first area that the sensor detects at a first point in time and one second area, which the sensor detects at a later, second point in time.
- This can be done by a relative movement between the package and the sensor, e.g. in the case of a fixed sensor, the package with its entire length in Longitudinal direction past the sensor.
- a section checked in this way corresponds to z. B. the entire length of a cigarette stick along their side wall.
- the sensor or a processing unit downstream of the sensor is on the one hand for comparison of an actual or current reflection or absorption characteristic with an expected reflection or absorption characteristic and on the other hand to issue an error signal in the event of a Deviation between actual and expected reflection or absorption characteristics intended.
- the actual or current reflection or Absorption characteristic is the one that is related to the one checked Area of the pack is determined. With the expected reflection or absorption characteristics it is an experimentally or arithmetically determined Comparison size for correctly positioned and aligned objects. This The comparison variable is stored in the sensor or in the processing unit. To the Weed out a package identified as defective or to prepare the In addition to such a pack, suitable organs are provided which are in Can be controlled depending on the error signal.
- Fig. 1 shows a side view of one in connection with the present Invention relevant section from a machine 10 for transport and Checking cigarette sticks 11.
- the cigarette sticks 11 are used as a pack stack provided in the form of a cyclically moving stacking tower 12, wherein the uppermost cigarette rod 11 is removed from the stacking tower 12 becomes. This takes place through the lower run of a conveyor belt provided with drivers 13 14, in a manner known per se via a deflection or drive roller 15, 16 is guided.
- Each cigarette rod 11 removed from the stacking tower 12 is arranged by the respective driver 13 and one opposite Stop 17 on a support plate 18 for checking on a radar sensor 19 executed sensor passed. From the cigarette sticks 11 one of its side walls is shown.
- One cigarette stick 11 each is at a standstill conveyor belt 14 between which is above the Stacking tower 12 located driver 13 and the associated stop 17th positioned.
- the machine 10 thus operates in a cyclical mode. The verification the cigarette rods 11 take place during a movement cycle of the machine 10th
- the or each radar sensor 19 is arranged and aligned such that radiated electromagnetic waves an area of one of the side walls that Test wall, grasp the cigarette rod 11 and at least partially penetrate and reflected electromagnetic waves can be detected by the radar sensor 19.
- the radar sensor 19 thus comprises both a transmitter and a receiver for electromagnetic waves.
- the reflection characteristic can of the cigarette sticks 11 are examined.
- Corresponds to the Reflection characteristic of an expected reflection characteristic will be like this assumed that the cigarette rod 11 with regard to the contained cigarette packs (two rows of cigarette packs arranged side by side) is correct and complete.
- the expected reflection characteristic arises on the other hand, the cigarette rod 11 in question is discarded. This e.g. by means of a laterally acting slide, not shown.
- a such discarded cigarette rod 20 passes through a waste shaft 21 into a waste container 22.
- FIG. 2 shows a detail of machine 10 outlined in dash-dotted lines in FIG. 1 with the conveyor belt 14 and individual cigarette sticks 11.
- For each cigarette stick 11 is the position of the cigarette packs 23 grouped therein indicated by the dashed contours. It can be seen that in every cigarette stick 11 ten cigarette packs 23 in two layers 24, 25 of five each Cigarette packs 23 are arranged.
- the radar sensor 19 is centered on the lower layer 24 of the cigarette packs 23 directed.
- the direction of transport of the Conveyor belt 14 is indicated by the horizontal block arrows. In this direction each cigarette stick 11 with the individual cigarette packs 23 on guided past the stationary radar sensor 19. In the constellation shown is missing in the currently checked cigarette rod 11 in its lower position 24 the middle pack of cigarettes 23.
- the electromagnetic ones emitted by the radar sensor 19 Waves are not reflected in this area in the way as would be the case if there was a cigarette packet in the appropriate position 23 would be present. This results in a deviation from the actual one Reflection characteristic from the expected reflection characteristic, so that the faultiness of the cigarette rod 11 can be recognized therefrom.
- Fig. 3a shows a sectional view along the line III-III (Fig. 2). In this illustration the conveyor belt 14 and deflection or drive roller 15 are visible. At the Conveyor belt 14 are provided for transporting the individual cigarette rods 11 Driver 13 and stops 17 arranged. Conveyor belt 14 and driver 13 are thus the means that a relative movement between the individual Cigarette rod 11 and the sensor designed as a radar sensor 19.
- the two layers 24, 25 contained therein are of cigarette packs 23 indicated by the dashed (dividing) line.
- Both layers 24, 25 of cigarette packs 23 are two radar sensors 19 provided, of which only one was visible in Fig. 2.
- the one already in FIG. 2 visible radar sensor 19 is used to check the lower layer 24 and the one shown in FIG. 3 additionally visible radar sensor 19 is used to check the upper layer 25 Cigarette packs 23 are provided.
- the radar sensors 19 are alternately on opposite side walls (test walls) the cigarette rod 11 arranged, each radar sensor 19 one Location 24, 25 is assigned.
- each layer 24, 25 of cigarette packs 23 additional radar sensor 26 (shown in dashed lines) is shown. With the radar sensor 19 and the additional arranged opposite in the same plane Radar sensor 26 becomes two opposite side walls of the cigarette rod 11 recorded. Each layer 24, 25 of cigarette packs 23 is thus on both sides checked. In this way, even the special case of an incorrectly positioned one Cigarette pack 23 can be recognized, in which this from the inside on a of the side walls (test walls) of the packaging of the cigarette rod 11 and thus roughly to a reflection characteristic like a correctly positioned one Cigarette pack 23 leads. You can also use two opposite Radar sensors 19, 26 the individual cigarette packs 23 with respect to Filter and tobacco side, i.e.
- FIG 3b shows an alternative embodiment of the in the sectional view of FIG 3a shows the detail of the machine 10.
- the difference to the embodiment 3a is that instead of the radar sensors 19 each Layer 24, 25 of cigarette packs 23 as a transmitter / receiver pair 37, 38 associated sensor.
- the transmitter 37 is electromagnetic for transmission Waves and the receiver 38 accordingly for receiving such electromagnetic Suitable for waves.
- the type of electromagnetic radiation used, So the frequency range is chosen so that, on the one hand, sufficient absorption the radiation given by the cigarette packs 23 and on the other hand penetration of the outer casing of the cigarette rod 11 is possible.
- the alternative embodiment is namely based on the evaluation of the absorption characteristic the cigarette rod 11.
- Transmitter 37 and receiver 38 are correct in a straight line parallel to the longitudinal axis oriented cigarette packs 23 in a cigarette rod 11 on opposite Arranged sides of the cigarette rod 11.
- the two transmitter / receiver pairs 37, 38 in different Frequency ranges work. This can also be an undesirable avoid mutual interference.
- Both preferred Embodiments can of course also be combined with one another. The Using different frequency ranges is also opposite in the case of two arranged radar sensors 19 (Fig. 3a) useful.
- Fig. 4 shows a layer 24, 25, e.g. the lower one Layer 24, of cigarette packs 23, whose through the conveyor belt 14 (Fig. 2) direction of movement is shown by the horizontal arrow.
- first error point 27 the place of the missing cigarette pack
- second fault location 28 results for that from the radar sensor 19 emitted electromagnetic waves a different reflection characteristic than in the area of the two correctly positioned cigarette packs 23.
- FIG. 5 shows in a coordinate system in which the time is on the abscissa (or a path) and on the ordinate a signal strength is plotted, a first one Signal curve 29 (shown in dashed lines) as it is with correct cigarette sticks 11, as well as a second signal curve 30, as it e.g. in the 4 configures a defective cigarette stick 11.
- the term signal curve becomes synonymous with the term already used Reflection characteristics used, because the waveform describes exactly the reflection characteristics of the objects examined, namely those in the cigarette stick 11 summarized cigarette packs 23.
- the respective Waveforms 29, 30 are at least in a memory, not shown partially, especially point, piece or section, recorded or deposited. Such a memory is the sensor or a subordinate to the sensor, also assigned processing unit, not shown.
- each maximum 31 corresponds each with a cigarette pack 23, of which also in a cigarette stick 11 five in a layer 24, 25 are arranged side by side. Any maximum 31 corresponds to one caused by the respective cigarette pack 23 Reflection of the emitted electromagnetic waves. On the borderline between two adjacent, correctly aligned cigarette packs 23 forms a minimum 32, because at such a point Reflection is reduced accordingly.
- the position designated 35 on the first or second signal curve 29, 30 corresponds to the position of the radar sensor 19 in relation to the cigarette rod 11, as shown in Fig. 4. After the radar sensor 19 in this position an area of the cigarette rod 11 with an existing cigarette pack 23, a maximum 31, 33 results accordingly in the signal curve 29, 30.
- the first waveform 29 corresponds to an expected waveform and each actual waveform, e.g. B. the second waveform 30 shown compared with this expected waveform. Agree more actual and expected A signal path within a predefined limit is a cigarette rod 11 or the respectively checked position 24, 25 in a cigarette stick 11 as evaluated correctly. However, if there are deviations, this is considered an error evaluated, an error signal generated and the cigarette stick recognized as defective 11 discarded.
- the examination or the comparison of the signal profiles 29, 30 preferably takes place on the basis of data stored for this purpose in the memory.
- the correspondence between the actual and expected signal curve can also be determined by "counting" the maxima 31 and minima 32.
- the Maxima 31 can be considered.
- the filter pages and the tobacco sides of cigarettes in terms of their reflection characteristics, so that the level of the local maximum 31 in the signal curve the filter-side ends of the cigarettes are different from those tobacco-side ends. It can thus be recognized whether cigarette packs are in a layer 24, 25 23 all cigarette packs 23 evenly and correctly are oriented, i.e. whether the filter pages in all cigarette packs 23 Direction and the tobacco sides of the cigarettes are oriented in one direction.
- the period of time during which the examination of the reflection characteristic or absorption characteristic is carried out can be specified that one in the radiation range of the respective sensor (radar sensor 19; Transmitter / receiver pair 37, 38) entering cigarette rod 11 on this Locally arranged light barrier, not shown, breaks through. That from the The signal delivered by the light barrier defines the start of an evaluation window. The end of the evaluation window results from a given one, if necessary or predeterminable follow - up time at which the the light barrier delivered signal changes, the cigarette rod 11 the Radiation area of the sensor has passed. Alternatively, there is also the possibility the evaluation window with regard to reaching threshold values Define encoder. So if such a pulse generator e.g.
- the invention can also be used to identify the completeness of a cigarette group used in a cigarette pack (not shown). Also a group of cigarettes is like a cigarette stick made up of individual layers next to each other arranged objects, namely the cigarettes. With a three-layer Cigarette groups are three sensors for checking each cigarette layer intended. In order to also check the correct orientation of cigarettes To be able to, there are two for each cigarette layer opposite in the same plane arranged radar sensors are provided.
- FIG. 6 largely corresponds to the representation according to FIG. 4 Avoid repetition, refer to the description of FIG. 4.
- the cigarette rod 11 is not on the radar sensor 19 but passed in the longitudinal direction between a transmitter / receiver pair 37, 38.
- the error points 27, 28 shown for the Transmitter 37 emitted electromagnetic waves have a different absorption characteristic than in the area of the two correctly positioned cigarette packs 23rd
- FIG. 7 shows (analogous to the representation in FIG. 5) in a coordinate system, in time (or a path) on the abscissa and signal strength on the ordinate is removed, a third signal curve 39 (shown in dashed lines) as it sets in with correct cigarette sticks 11, and a fourth signal curve 40 as it e.g. in the constellation shown in FIG. 6 a faulty one Cigarette stick 11 sets.
- the term signal curve becomes synonymous with already used term absorption characteristics used because the signal curve this time exactly describes the absorption characteristics of the checked ones Cigarette packs 23.
- the respective signal profiles 39, 40 are in one Memory, not shown, at least partially, in particular point, piece or in sections, recorded or deposited. Such a memory is the sensor or a processing unit downstream of the sensor, likewise not shown assigned.
- the third signal curve 39 - which is partially covered by the fourth signal curve 40 is - is characterized by an over the entire length of the cigarette rod 11 in Signal level remains essentially constant. Only on the sides of the Cigarette rod 11 the signal level rises markedly because there is no cigarette rod here 11 is located between the transmitter / receiver pair 37, 38 and accordingly no absorption takes place, so that the complete transmitter 37 emitted radiation reaches the receiver 38.
- the fourth signal curve 40 there are clear peaks 41, 42, that is to say regions with increased signal level.
- the first of the two peaks 41 is from the missing cigarette packet, the first fault location 27 (FIG. 6). Due to the lack of a cigarette pack, there is a significantly reduced rate Absorption of the electromagnetic waves, so that almost the complete, Radiation emitted by the transmitter 37 reaches the receiver 38.
- the incorrectly oriented cigarette pack (FIG. 6)
- the fourth signal curve 40 rises earlier than the third waveform 39 on. This is due to the fact that the incorrectly oriented cigarette packet 23 of the second fault location 28 a gap between the cigarette pack 23 and the edge of the outer wrapper the cigarette stick 11 remains. It also happens in the area of this gap a reduced absorption, so that the cigarette rod 11 when viewed only the absorption characteristic appears to be "shorter" overall.
- the position designated 35 on the third or fourth signal curve 39, 40 corresponds to the position of the transmitter / receiver pair 37, 38 in relation to the cigarette rod 11, as shown in Fig. 6. After the transmitter / receiver pair 37, 38 in this position with an area of the cigarette rod 11 of an existing cigarette pack 23 is determined accordingly high absorption of electromagnetic radiation and thus in the signal curve 39, 40 a low signal level.
- the third waveform 39 corresponds to an expected waveform and each actual waveform, e.g. B. the fourth waveform 40 shown when evaluating the absorption characteristic with this expected signal curve compared.
- the investigation or comparison of the signal profiles 39, 40 takes place on the basis of the data stored for this purpose in the memory.
- a particularly simple way of comparing the actual absorption characteristics with the expected absorption characteristic results if a threshold value 36, which is above the correct cigarette packets 23 setting signal levels is introduced. Then when checking examines whether this threshold 36 during the entire length checked the cigarette rod 11 is exceeded. As soon as this happens, there is one Deviation from the expected absorption characteristic before, indicating the defectiveness the checked cigarette rod 11 can be seen. In this review it is not necessary to save the two signal profiles 39, 40. A comparison of the current signal level with the threshold value 36 sufficient.
