Definitions

  • the invention relates to a device for conveying a strand of the tobacco processing industry in a conveying direction with a strand conveyor belt and a plurality of guiding elements leading the strand conveyor belt.
  • the invention further relates to a method for conveying a strand of the tobacco processing industry by means of a strand conveyor belt, comprising the step of guiding the rope conveyor belt.
  • Such devices and methods are used in a cigarette rod machine to collect the tobacco, which is supplied in the form of a shower to the bottom of a strand guide channel forming strand conveyor, in a strand formation zone and from this - if necessary, through an excess removal device through - remove.
  • a strand conveyor the lower strand of an air-permeable, acted upon from its back with negative pressure, endless, circulating suction belt is used in modern cigarette rod making machines, so that this type of conveyor is also referred to as Saugstranger.
  • the lower strand of the suction belt, on which the accumulated tobacco fiber strand is suspended suspended is referred to below.
  • the strand conveyor extends in the tobacco channel from the beginning of the Stranding zone through a region of an excess removal device, in which a Egalizer or trimmer excess tobacco from the tobacco rod, to a discharge end, at which the tobacco rod formed to another conveyor, preferably to a format strip of a string unit, is delivered.
  • the tobacco rod is placed on a driven, covered with a cigarette paper strip format tape.
  • the format tape transports the tobacco rod and the cigarette paper strip through a format in which the cigarette paper strip is placed around the tobacco rod and glued, so that a cigarette rod is formed, which is finally processed into cigarettes or filter cigarettes.
  • Input devices are known from the prior art.
  • the EP 0 999 761 B1 The applicant shows a device for conveying a strand of the tobacco processing industry, in which a defined flow profile over the length of the tobacco channel is adjustable.
  • the device of the EP 0 999 761 B1 specifically juxtaposed individual segments with different air passages for guiding the strand conveyor belt on.
  • the relatively small individual elements are made of highly wear-resistant material.
  • the EP 1 464 594 B1 The applicant shows a device for conveying a strand of the tobacco processing industry with a bearing for support rollers for supporting the strand conveyor belt.
  • the EP 1 169 926 A1 the applicant shows a device for conveying a strand of the tobacco processing industry with a on its tobacco-facing surface at least partially ceramic having channel.
  • the object of the present invention is to improve the devices and methods known from the prior art.
  • a device of the aforementioned type which is characterized in that the guide elements are partially formed as static supports and partly as movable supports, wherein the movable supports increased at least in a region of the device with respect to other areas of the device Pressure of the guide elements are arranged on the strand conveyor belt.
  • Embodiments of the device according to the invention surprisingly have the advantage that they reduce or even avoid several disadvantages of known Saugstrangdecier.
  • the wear of the strand conveyor belt and the noise generated by the Saugstrangdecier be significantly reduced.
  • the invention is based on the finding that the length of the conveyor line of the Saugstrangenseers and the high speed of modern cigarette rod making high demands on the course of a strand conveyor directly or indirectly influencing parts of the device, in particular, that a wear of the strand conveyor to a not insignificant part by Friction between the static guide elements and the strand conveyor belt and associated with the friction heat generation is caused especially at high speeds and the friction in turn depends on the pressure of the guide elements on the strand conveyor.
  • Static guide elements are stuck to the strand conveyor, i. In operation, a relative movement of strand conveyor to static guide elements. In this way, in the leadership of the strand conveyor belt friction between the static guide elements and the strand conveyor belt, which is greater, the greater the pressure of the guide elements on the strand conveyor or the strand conveyor belt is on the guide elements. In places or areas of the strand conveyor belt, where this friction between static guide elements and the strand conveyor belt becomes too large, damage to the rope conveyor belt can occur.
  • the invention is further based on the finding that with increasing conveying speed of strand conveyors, the increased noise development is due in particular to the movable supports.
  • the invention further includes the recognition that a suction belt conveyor has significantly fewer areas with a critical pressure than areas with a non-critical pressure.
  • the noise development of the Saugstrangadders invention can be kept low overall, since the relevant for the noise largely responsible movable supports are arranged only in those areas of the device with critical pressure. Therefore, moving pads are usually required only in a few areas and the noise level remains low. In large parts of the device where no critical pressure occurs, however, static pads are used with less noise than moving pads.
  • the invention may be further developed in that the guide elements are arranged in at least two sections, wherein in one of the two sections, the strand conveyor is guided only by the movable supports and in the other of the two sections only by the static constraints, and wherein the sections are arranged, that the strand conveyor belt passes the sections in the conveying direction successively.
  • the strand conveyor belt is guided in sections, either by static conditions or by movable supports.
  • the sections are arranged consecutively in the conveying direction.
  • the invention can be developed by arranging the movable supports in a region of the device with a change of the conveying direction.
  • This embodiment of the invention is based on the recognition that a critical pressure occurs in particular where the strand conveyor changes the conveying direction.
  • a promotion of the strand in a constant over the entire conveyor line conveying direction, for example in the horizontal, is often not possible. Rather, it is usually necessary to change the conveying direction in sections, for example by changing the conveying direction of the horizontal in an inclined conveying direction, for example, with a deflection of the strand conveyor belt relative to the horizontal of a few degrees.
  • Such a change in the direction of conveyance leads to an increased pressure, which can lead to a critical load of the strand conveyor belt when using static supports with the disadvantages described above.
  • movable supports are therefore provided in areas with a change in the conveying direction.
  • the invention can be developed by arranging the movable supports in a region of the device with an elevation and / or lowering of the strand conveyor belt substantially perpendicular to the conveying direction.
  • This embodiment of the invention is based on the finding that in areas in which the strand conveyor belt is lowered and / or raised, also a critical pressure with the disadvantages described above can occur.
  • An increase and / or a lowering of the strand conveyor belt is required, for example, depending on the strand weight.
  • An increase and / or reduction of the strand conveyor belt is furthermore preferred in the region of the excess removal device in order to be able to control the amount of tobacco to be taken from the tobacco tobacco that has been quenched.
  • the lifting and / or lowering preferably takes place substantially perpendicular to the conveying direction, ie essentially in a vertical direction.
  • afflicted with elevated pressure Area of the device movable pads provided with the advantages described above.
  • the invention can be further developed in that at least one of the movable supports is adjustable in a direction substantially perpendicular to the conveying direction in order to lift and / or lower the strand conveyor belt substantially perpendicular to the conveying direction.
  • the movable supports are or can be adjustable in this way, that they can follow an increase and / or reduction of the strand conveyor belt or initiate this increase and / or reduction of the strand conveyor belt or can.
  • the invention can be developed by arranging the movable supports in a region of the device in which the device is designed to deliver a strand to a further conveying device, preferably a format strip. Furthermore, it is preferred that the movable supports are arranged in a region of the device which lies in the conveying direction adjacent to a region of the device in which the device is designed to deliver a strand to a further conveying device, preferably a format strip
  • the invention can be developed by arranging the movable supports in a region of the device in which the device is designed to cooperate with an excess removal device. It is further preferred that the movable supports are arranged in a region of the device which lies in the conveying direction adjacent to a region of the device in which the device is designed to cooperate with an excess removal device.
  • This training according to the invention is based on the finding that the area in which excess tobacco is removed from the tobacco tobacco which has been suppressed by an excess removal device is likewise an area in which a critical pressure frequently occurs. It is therefore also preferred here to provide movable supports in order to realize the above-mentioned advantages.
  • the excess removal device usually designed as a trimmer or equalizer, often requires a lowering and / or lifting of the strand conveyor belt, often in response to the size of the trim discs used in the excess removal device. Furthermore, it is often desirable or necessary to provide a change in the direction of conveyance in the region before interacting with the excess removal device. A change in the conveying direction before the region of interaction with the excess removal device is particularly preferred when the excess removal device has large trim disks. It is therefore particularly preferred to combine the training forms mentioned above in connection with the raising and / or lowering of the strand conveyor belt, the corresponding adjustability of the movable supports and with the change of the conveying direction with the training forms mentioned here.
  • the object mentioned is achieved by a method of the type mentioned, which is characterized in that the guiding of the strand conveyor belt by means of a plurality of guide elements, which are designed partly as static conditions and partly as movable supports, and wherein the strand conveyor belt is guided through the movable supports at least in one area with an increased pressure of the guide elements on other parts in relation to other areas.
