Definitions

  • the invention relates to a device for checking the ends of cigarettes in the area of upright test channels, in which individual rows of superposed cigarettes with their ends directed sideways are moved from top to bottom, in particular in a cigarette magazine of a packaging machine, in the area
  • a test unit with sensors, namely transmitters and receivers for emitting and receiving a test beam in the region of end surfaces of a test group of cigarettes and their adjacent side surfaces, is arranged on a test plane on at least one side of the test channels.
  • Such a test device is the subject of EP-A-0 338 241. It is a matter of checking the two end regions of the cigarettes with regard to correct formation, namely with regard to sufficient tobacco filling and possibly with the presence of a filter. Faulty cigarettes are identified and ejected from the cigarette magazine. There is a test unit on both sides of the cigarette magazine on one test level. This is equipped with transmitters and receivers. The transmitters direct light onto the end or end faces of the cigarettes in a test group. In a region adjacent to the end faces, receivers are arranged on both sides of the cigarettes to be tested, which receive the light passing through the side faces, that is to say through cigarette paper. A too strong light emission is an indication of the incorrect formation of the cigarette. In the known device, two superimposed sensors are arranged as receivers on both sides of each cigarette, one to ensure as accurate a check as possible.
  • the invention is based on the object of further developing and improving a test device of this or a similar design with regard to the arrangement and design of the sensors and with regard to the structural design of the test unit in the sense of simplified design and handling as well as more reliable testing.
  • the device according to the invention is characterized in that light-sensitive receivers each extend over the area of a test group with several, in particular two cigarettes lying one above the other, and receive light coming from each of the cigarettes in a test group, preferably in the area of the side surfaces.
  • receivers are assigned to the cigarettes of a test group, preferably two cigarettes one above the other, which extend as a unit or as a unitary organ over the area of the (two) cigarettes. This ensures that a larger receiving surface is available for the light emerging from the cigarettes (on the side). This makes the check more precise.
  • the receivers are sheet-like silicon photo elements, which are also known as solar cells.
  • the procedure according to the invention is such that during one test cycle the test beam (light) is first applied to one and then the other cigarette.
  • the flat receiver common to both cigarettes is accordingly first exposed to light from one and then the other cigarette.
  • test unit Another special feature of the invention relates to the training of the test unit. Overall, this can be moved in cycles across the test channels or in the longitudinal direction of the cigarettes. For the downward transport of the cigarettes after a test cycle, the test unit is withdrawn so that the cigarettes can be moved freely. For the test cycle, the test unit is moved towards the ends of the cigarettes.
  • test unit Another special feature is the composition of the test unit from individual test organs, each of which is assigned to a cigarette or a test group.
  • the U-shaped test organs, each with the sensors required for a test group, are assembled side by side to form a test unit, with easily detachable connecting elements. This simplifies the assembly of the test unit. Furthermore, later replacement, repair and cleaning of individual test organs is possible.
  • a positioning unit for the elastic and individual pressurization of the cigarettes in the longitudinal direction thereof is arranged on one side of the test channel or cigarette magazine.
  • test organs and their sensors as well as the test unit and their actuation.
  • the details shown in the drawings relate to the testing of cigarettes 10 with a filter 11 with regard to the correct formation of end regions.
  • the cigarettes 10 are put into a cigarette magazine 12 in a disorganized but aligned position.
  • the basic structure of this corresponds approximately to the cigarette magazine according to EP-A-0 338 241.
  • the cigarettes pass through a test area 13 which is on the widest point is arranged within an upwardly and downwardly converging magazine housing 14.
  • the tested and intact cigarettes 10 reach a collecting space 15 below the test area 13. From there, the cigarettes are introduced into upright magazine shafts 16. At the lower end of the magazine shafts 16 formed in groups, the cigarettes 10 are pushed out as cigarette groups in accordance with the contents of a pack.
  • the test area 13 also consists of a number of upright shafts or test channels 17 arranged parallel to one another, the width of which is slightly larger than the diameter of a cigarette, so that within the test channels 17 in each case rows of cigarettes 18 are formed from individual, stacked cigarettes. The cigarettes 10 or rows of cigarettes 18 are moved downward within the test channels 17 due to their own weight.
  • the test channels 17 are separated from one another by web-like channel walls 19.
  • the cigarettes 10 are checked in the area of a test level 20 of the test area 13. During a test cycle, a plurality of cigarettes 10 lying one above the other are checked in each test channel 17. In the present case, this test group 45 consists of two cigarettes 10 lying one above the other.
  • the arrangement is such that the cigarettes 10 are fixed within the test channels 17 so that the test can be carried out while the cigarettes 10 are exactly at rest.
  • holding members for the cigarettes 10 are provided in the test channels 17 below the test level 20, namely elongated clamping members, namely clamping fingers 21. These are stored in lateral recesses in the channel walls 19 and each fix a cigarette 10 by pressing against the opposite channel wall 19. As a result, the overlying part of the rows of cigarettes 18 is also positioned.
  • a movable support member for the cigarettes 10 is arranged at a distance below the horizontal plane formed by the clamping fingers 21, namely a comb 22 extending across the test area 13 with webs 23 assigned to each test channel 17.
  • the comb 22 extends as a unit in the horizontal plane - and slidable. In one position (FIG. 1), the webs 23 are located in the region of the test channels 17. The rows of cigarettes 18 located above the comb 22 are supported on the webs 23. In this position, any defective cigarettes 10 can be ejected below the clamping fingers 21, that is to say in a region formed by two exposed cigarettes 10, by organs (not shown) which act in the longitudinal direction of the cigarettes.
  • test channels 17 are released downwards.
  • the webs 23 are located in the region of the (intermittent) channel walls 19. Interstices formed between the webs 23 are congruent within the test channels 17.
  • the tested and intact cigarettes 10 can now fall into the collecting space 17.
  • the test channels 17 are extended downward beyond the level of the comb 22 by appropriately dimensioned or elongated channel walls 19.
  • the cigarettes 10 are checked in the test plane 20 by a specially designed test unit with regard to the correct formation of the end regions.
  • the test unit consists of two test units 24, 25, which are arranged in the test plane 20 on both sides of the cigarette magazine 12.
  • the test units 24, 25 form upright depressions or recesses 26 analogously to the device according to EP-A-0 338 241.
  • the cigarettes 10 enter these upright recesses 26 during the downward movement, each with an end region. This is then checked during a test cycle.
  • each cigarette 10 or each cigarette end There is a sensor adjacent to each end face 27 of the cigarettes 10, namely a transmitter 28, 29. This sends a test beam, namely a light beam, in the longitudinal direction into the cigarette 10 to be tested.
  • the cigarettes 10 are sensors arranged on both sides assigned, which act as receivers 30, 31. These are designed and arranged in a special way. These are flat or plate-shaped, light-sensitive sensors, in particular silicon photo elements in planar technology. These receive light over the entire surface, so that a large measuring range is available.
  • the two cigarettes 10 of the test group 45 have a common receiver 30, 31 available on both opposite sides.
  • the test is expediently carried out such that the two cigarettes 10 of the test group 45 are tested in successive steps during a test cycle, so that the receivers 30, 31 are each available for one cigarette. This leads to a particularly precise check, namely the distinction between cigarettes that are still considered correct and faulty ones.
  • test units 24 and 25 have a special design.
  • Individual test organs 33 are detachably or removably attached to an elongated carrier 32, which is designed here as an uneven double T-profile.
