Definitions

  • ABSTRACT A cutoff for a continuously moving cigarette rod or the like has a rod guide which cooperates with the orbiting knife or knives and is reciprocated by an adjustable crank drive.
  • the latter has a cylindrical imput member which is driven by a shaft in synchronism with the knife or knives and has an eccentric socket for a cylindrical output member having an eccentric crank pin which can reciprocate the guide by way of a linkage consisting of a pivotable lever and a connecting rod.
  • the eccentricity of the crank pin relative to the output member equals the eccentricity of the socket relative to the input member, and the output member is angularly adjustable in the socket to thus select the throw of the crank pin.
  • the output member is balanced with respect to its axis prior to assembly of the crank drive, and the entire crank drive is balanced upon insertion of the output member into the socket.
  • the mass of the crank drive exceeds the mass of the linkage.
  • the present invention relates to apparatus for severing rods which consist of or contain tobacco, filter material and/or other fibrous substances and are surrounded by tubular wrappers consisting of cigarette paper, reconstituted tobacco or the like. More particularly, the invention relates to apparatus for subdividing continuous wrapped rods of tobacco or filter material into sections of unit length or multiple unit length.
  • the subdividing or severing apparatus (known as a cutoff) comprises one or more orbiting knives which intersect at preselected intervals the path wherein a wrapped filler rod moves lengthwise so as to subdivide the rod into sections of required length.
  • the knives are normally orbited in such a way that each thereof has a component of movement in the direction of lengthwise movement of the rod during severing of the wrapper and filler to thereby insure the formation of clean cuts and to further insure that the rod is severed in planes which are normal to its axis.
  • a guide which comprises one or more tubes wherein the rod moves at the severing station whereby the tube or tubes support the rod during severing and thus contribing of cigarette rod in planes other than those which are normal to the axis of the rod affects the appearance of plain cigarettes and/or filter cigarettes which employ such plain cigarettes, it is highly desirable to make sure that the knife or knives will sever the rod only while moving in a plane which is exactly normal to the rod axis. Consequently, and since the tube or tubes of the aforementioned guide serve as a counterknife, they must move with and at the exact speed of the moving rod during each severing operation.
  • the guide employs two tubes which define a gap for the passage of the knife or knives or a single tube having a slot through which the knife or knives travel during severing of the cigarette rod.
  • Such mode of operation of the severing device is quite satisfactory when the speed of the rod is below a certain value.
  • several problems arise when the cutoff is to sever the rod at such high frequency that the machine which embodies the cutoff turns out up to and in excess of 4,000 cigarettes ute to the formation of clean cuts.
  • the tube or tubes are normally reciprocated by a crank assembly which causes them to move in the direction and at the exact speed of movement of the rod during each of a series of consecutive severing operations.
  • a crank assembly which causes them to move in the direction and at the exact speed of movement of the rod during each of a series of consecutive severing operations.
  • the severing apparatus of Niemann et al., and Bardenhagen may be used for severingof continuous rods which contain fillers of tobacco and/or filter material and tubular wrappers of cigarette paper, reconstituted tobacco or the like, as well as continuous rods which constitute hollow tubes suitable for use in the making of certain types of filter mouthpieces or in the making of smokers products known as papyrossi.
  • severing apparatus of Niemann et al., and Bardenhagen, as well as the severing apparatus of the present invention, may be used for severingof continuous rods which contain fillers of tobacco and/or filter material and tubular wrappers of cigarette paper, reconstituted tobacco or the like, as well as continuous rods which constitute hollow tubes suitable for use in the making of certain types of filter mouthpieces or in the making of smokers products known as papyrossi.
  • reference will be had (for the sake of simplicity and convenience) to apparatus for severing per minute.
  • the mass of the guide which is reciprocated at a frequency of 4,000 oscillations per minute subjects the material of and the bearings for its moving parts as well as the material of and the bearings for the parts of the crank assembly to enormous stresses.
  • the inertia of moving parts of the guide and crank assembly is such that these units of the cutoff generate excessive noise which is often unbearable to attendants.
  • crank assembly Proper balancing or truing of conventional crank assemblies for the guides of cutoffs was considered impractical or plain impossible because the crank assembly must be adjustable so as to enable the cutoff to subdivide the cigarette rod .into longer or shorter cigarettes. Thus, if a conventional crank assembly is properly balanced when the guide is to perform strokes of a first length, it is not balanced when the guide is to perform longer or shorter strokes.
  • the length of I cigarettes will vary within a range of up to and in excess cigarette rods which contain fillers of tobacco and tubular wrappers of cigarette paper or reconstituted tobacco with the understanding, however, that such apparatus are equally suited for the severing of empty tubes, tubular wrappers which contain cigar or cigarillo fillers, and/or tubular wrappers which contain filter material.
  • the guide which includes one or more tubes through which the cigarette rod passes, further serves as a counterknife for the orbiting knife or knives of the cutoff.
  • the cigarette rod moves continuously, ie., also during severing, and at a substantial speed which, in a modem cigarette rod making machine, can. approximate or even exceeds 350 meters per minute. Since the severof 20 millimeters so that, if the crank assembly is properly balanced at a time when it is set to move the guide through strokes of shortest length, it is invariably unbalanced when the guide is to perform strokes of maximum length. This results in the generation of excessive noise as well as in excessive wear upon the moving parts and their bearings when the cutoff is set to subdivide the rod into cigarettes of maximum length.
  • An object of the invention is to provide a cutoff for continuous cigarette rods or the like with a novel and improved guide and with a novel and improved drive for the guide, and to construct and assembly the drive in such a way that it is properly balanced irrespective of the length of strokes which the guide must perform in'and counter to the direction of lengthwise movement of the rod.
  • Another object of the invention is to provide a cutoff with a novel and improved crank assembly which off and which is constructed and assembled in such a way that it runs true irrespective of the selected length of strokes of the guide in and counter to the direction of movement of the rod.
  • a further object of the invention is to provide a crank assembly which can be rapidly and accurately adjusted to move the guide through strokes of desired length.
  • An additional object of the invention is to provide a crank assembly whose balance is altered very little or not at all if its parts are adjusted for the purpose of changing the length of strokes of the guide.
  • Still another object of the invention is to provide a crank assembly which can be used as a superior substitute for the crank assemblies of conventional cutoffs for cigarette rods or the like.
  • the invention is embodied in an apparatus for severing a continuous rod which moves lengthwise in a predetermined direction and at a predetermined speed, particularly for severing a rod which consists of a tube or wherein a tubular wrapper surrounds a filler of fibrous material.
  • the severing apparatus comprises a substantially tubular guide defining a portion of the path for the rod and being movable in and counter to the direction of movement of the rod through distances of variable length, drive means for moving the guide, and motion transmitting means articulately connecting the guide with the drive means.
  • the drive means constitutes a crank assembly which comprises a preferably cylindrical input member rotatably by a drive shaft about a first axis and provided with a preferably cylindrical socket having a second axis which is parallel to and spaced apart from the first axis by a first distance, and a preferably cylindrical output member angularly adjustably mounted in the socket and having a third axis which coincides with the second axis.
  • the output member includes an eccentric portion which drives the motion transmittingmeans and has a fourth axis parallel to and spaced apart from the third axis by a second distance which preferably equals the first distance so that the axis of the eccentric portion may coincide with the first axis in a neutral angular position of the output member in which the throw of the eccentric portion is zero.
  • the output member is balanced prior to insertion into the socket, and the entire crank assembly is balanced upon insertion of the output member into the socket. If desired, the output member can be balanced together with a component part of the motion transmitting means.

  • the thus coated marginal portion is thereupon folded over the one marginal portion to form therewith a seam which extends lengthwise of v the resulting cigarette rod 19 and is heated by a sealer 18 which causes the adhesive to set so that the tubular wrapper of the rod 19 does not open during subdivision of the rod into sections (plain cigarettes) of unit length or multiple unit length.
