Definitions

  • the invention relates to a device for heating the adhesive seam of a strand of the tobacco processing industry which is moved in the longitudinal axial direction, the filling of which is surrounded by a wrapping material strip, the outer edge and the region adjoining it overlap an inner region of the strip, wherein in the overlap region, the adhesive seam, Adhesive.
  • a filling which can consist of smoke material such as tobacco or filter material
  • a wrapping strip such as cigarette paper or filter paper in such a way that the outer edge and the area adjacent to it form an inner area of the strip overlaps. Both areas are glued together with adhesive, creating the so-called adhesive seam, which prevents the wrapping from opening. Then cigarettes or filter sticks are cut off from the strand thus wrapped.
  • the adhesive can consist of aqueous substances such as pasty starch, dispersed polyvinyl acetate particles or gelatin, which were used for gluing cigarette paper.
  • a thin layer of glue is usually applied to the area of the cigarette paper strip adjacent to the edge, this area is pressed and heated to form an adhesive seam on an inner area of the strip, whereby the adhesive solidifies.
  • Hot-melt adhesive which solidifies by cooling, is mostly used to glue filter paper strips that envelop filter material.
  • the edge strip applied with hot-melt adhesive but heated before cooling to activate the hot melt adhesive before it is then solidified by cooling.
  • a device for gluing a strip of cigarette paper and for heating the formed adhesive seam of a cigarette rod in order to solidify the adhesive is known from US Pat. No. 3,507,288.
  • FR-A-120 842 shows a device for applying hot-melt adhesive to a filter paper strip, for activating the adhesive and then cooling the adhesive seam of a filter strand.
  • a bar heated by a heating cartridge, which is in direct contact with the moving glued seam and heats it up to solidify the adhesive.
  • the bar must first be heated up after longer breaks in operation, which takes time in which cigarette production is not possible.
  • care must be taken to ensure that the heating of the adhesive seam does not become too intense in the event of deviations from the stationary operating state, ie in particular at slower speeds of the cigarette rod, which would lead to overheating on the rod.
  • the solution according to the invention is that a radiation source is arranged at a distance from the adhesive seam, the radiation of which heats the adhesive seam indirectly or directly.
  • the invention has the advantage that the radiation sources, for. B. infrared emitters, have very low thermal inertia, which enables a quick influence of the heat flow supplied to the adhesive seam of a strand.
  • This property of radiation sources has a particularly advantageous effect if the radiation from the radiation source is directed directly onto the adhesive seam through a radiation-permeable body, because the thermal inertia is then very low.
  • the cigarette rod 1 moved perpendicularly to the drawing line consists of a filling 2 made of tobacco or other smokable material and of a rounded wrapping material strip in the form of a cigarette paper strip 3.
  • An edge 4 of the cigarette paper strip and the underside of the adjoining area has been provided with adhesive and is opened in an overlapping manner pressed the inner region 6 of the strip fan 3 so that a glue seam 7 is formed.
  • the application of the adhesive and conventional heating of the adhesive seam is shown, for example, in US Pat. No. 3,507,288 for a cigarette rod and FR-A-2,120,842 for a filter rod.
  • the adhesive seam 7 must be heated intensively to quickly solidify the adhesive.
  • a heat transfer body 8 is used, which can consist of a suitable metal such as aluminum or another suitable material with good heat conductivity. Its underside 9 is designed to be wear-resistant and can be anodized when aluminum is used.
  • the heat transfer body 8 is arranged in a stationary manner and in mechanical contact with the top of the area of the cigarette paper strip 3 bordering the edge 4 of the moving cigarette rod 1.
  • a radiation source 11 in the form of a rod-shaped infrared radiator 12, for. B. in the form of IRK, type X from PHILIPS, 54750 Point-A-Mousson, FR.
  • the infrared radiator 12 is located inside a housing 13, whose upper part 13a is mirrored on the inner wall 14.
  • the inner wall 14 has the shape of an ellipse, in whose one focal point 16 is the infrared radiator 12.
  • the heat rays emanating from the radiator upwards, to the sides and obliquely downwards, some of which are indicated by dash-dotted lines and denoted by 17, are directed from the elliptical mirrored inner wall 14 onto the heat transfer body 8 and heat it up relatively quickly, so that changes in the Radiation power is also quickly noticeable on the underside 9 of the heat transfer body 8 and thus the adhesive seam 7.
  • the radiation power of the infrared radiator 12 is controlled by a control arrangement 18 which has a temperature sensor 19, the output signal of which is fed to a comparison element 22 together with a signal emitted by a setpoint generator 21.
  • the output signal from the comparator 22 controls the electrical power supplied to the infrared radiator 12 and thus its radiation power (intensity), e.g. B. to constant temperature on the bottom 9th
  • a guide body can also be provided, which consists of an at least partially permeable to the radiation of the radiation jellyfish 11 material.
  • quartz glass or ceramics are suitable for infrared radiators.
  • Such a guide body which may have the shape of the heat transfer body 8 but can also be designed differently, is also in contact with the top of the area adjacent to the edge 4 of the cigarette paper strip and thus the moving adhesive seam 7.
  • the temperature can then be adjusted by means of a optical temperature probe that measures the temperature of the Glued seam or the cigarette paper is grasped.
  • the advantage of this embodiment is that the heat radiation, which can be imagined to be extended to the seam area, can heat the adhesive seam directly, so that the thermal inertia of the system is even less.
  • the radiator 11 can be controlled as a function of the speed of the cigarette rod 1 instead of by a heat sensor 19.
