Definitions

  • the present invention relates to a continuous belt for use with apparatus for high speed delivery of free flowing material.
  • the present invention according to a first embodiment is directed to a laminated belt for use in a device which delivers free flowing material into receiving spaces separating filter plugs, as the plugs move on a conveyor (in the tobacco art, such a conveyor is called a garniture tape).
  • the present invention according to a second embodiment includes a pair of parallel endless belts with a series of units called pockets suspended between them. It is particularly useful for delivery of free flowing material in cigarette manufacturing.
  • This invention is used in a device which delivers free flowing material, such as charcoal granules, into receiving spaces separating filter plugs, as the plugs move on a conveyor (in the tobacco art, such a conveyor is called a garniture tape).
  • U.S. 4,285,678 includes a belt. This belt travels around a plurality of wheels. During a portion of this travel; the belt moves parallel with and above the garniture tape.
  • the garniture tape carries a row of axially aligned filter plugs separated by receiving spaces so that:the filter plugs travel between the garniture tape and the belt.
  • the belt includes apertures registered with the receiving spaces separating the filter plugs. These apertures direct the free flowing material into the receiving spaces.
  • the blank portions of the belt screen the filter plugs from exposure to the free flowing material.
  • U.S. 3,464,324 includes a belt which travels over a row of filter plugs transported on a garniture tape(called a travelling folding tape in that patent). Granular material is deposited through apertures in this belt into the spaces between the plugs. The apertures in the belt are timed to register with the receiving spaces between the filter plugs.
  • U.S. 3,464,324 includes an alternative embodiment utilizing a linked chain.
  • This chain includes a web portion provided with a slot which allows the passage of granular material into voids separating filter plugs.
  • the links comprising such chains contain channels or funnels capable of channelling particulate matter.
  • the links travel adjacent to the axially aligned filter plugs.
  • the funnels within the links register with the spaces between the filter plugs, and a dispenser delivers particulate matter to the funnels within the links.
  • the funnels channel this particulate matter into the adjacent receiving spaces.
  • the belts in the prior art help screen the filter plugs from exposure to the free flowing material.
  • these belts do not hold the filter plugs in a stable position on the rapidly moving garniture tape.
  • the presently utilized chains can experience loss of tolerance in the connections between the individual links. Loss of tolerance in the connections causes variability in distance between the links, resulting in variability in distance between the apertures within the links. Due to this variability, apertures moving parallel with and adjacent to receiving spaces do not maintain registration with said spaces. This disfunction between apertures and receiving spaces results in inaccurate delivery of particulate material.
  • the present invention in one embodiment, provides a belt which is a lamination of a metal band and a composition strap.
  • This laminated belt travels around a plurality of wheels on a course in part parallel with and adjacent to that of a garniture tape carrying axially aligned filter plugs.
  • the composition strap conforms to the round shape of the filter plugs carried by the garniture tape. .
  • the laminated belt urges the filter plugs against the garniture tape thereby holding the plugs in place.
  • a plurality of apertures extend completely through the belt.
  • An independent means synchronizes the motion of the laminated belt with that of the garniture tape so that the apertures through the belt register with the receiving spaces between the filter plugs.
  • the blank portions of the belt register with the filter plugs, screening the filter plugs from exposure to the free flowing material.
  • the charcoal chute delivers particulate matter through the apertures in the belt into the receiving spaces separating the plugs.
  • this laminated belt maintains registry of the belt apertures with the receiving spaces, even as the garniture tape transports the plugs at high speeds. Such stable registry allows for accurate delivery of free flowing material at very high speeds, while the laminated belt masks the filter plugs from exposure to the free flowing material.
  • the present invention provides a device including two parallel endless belts with a series of units called pockets suspended between them. These pockets contain channels or funnels for channelling free flowing material.
  • a continuous belt for use with apparatus for constructing cigarette filters which in use moves in synchrony with and in part parallel to a garniture tape conveying filter plugs in axial alignment, the belt having channels therethrough for, in use, channelling free flowing material into spaces between the filter plugs in the garniture tape, characterised in that the surface of the belt which in use opposes the garniture tape has a profile corresponding to that of a filter plug in the garniture tape, so that, in use the filter plugs are urged against the garniture tape.
  • the continuous belt comprises a metal band and a composition strap laminated onto one side of the metal band such that, in use, the composition strap opposes the garniture tape.
  • the continuous belt comprises a continuous band having a plurality of individual pockets attached thereto such that, in use, the undersurface of the pockets opposes the garniture tape.
  • apparatus for inserting free flowing material into receiving spaces between filter plugs for use in constructing cigarette filters comprising a laminated belt having a metal band with a composition strap laminated on one side, the belt further having apertures and travelling in part parallel with and adjacent to a garniture tape carrying the filter plugs, while the apertures in the belt channel particulate matter into the receiving spaces between the filter plugs and non-apertured parts of the belt mask the filter plugs from free flowing material.
  • the laminated belt travels around a plurality of wheels so that the metal band contacts the wheels, the composition strap being laminated onto the side of the band away from the wheels, in an especially preferred form of the invention, the composition strap contacts the filter plugs as the laminated belt travels parallel with and adjacent to the garniture tape, the composition strap conforming to the shape of the filter plugs and the laminated belt urging the filter plugs against the garniture tape.

  • Composition strap 21 may be formed of neoprene or other suitable composition materials.
  • the neoprene composition strap 21 is molded from liquid neoprene,-which directly bonds to the metal band 20 without the need for adhesive.
  • the composition strap 21 terminates in a concave shape 53. This concave shape 53 closely conforms to the round shape of filter plugs 26 in the partially constructed cigarette filters.
  • Apertures 22 extend through both the metal band 20 and composition strap 21 portions of belt 10.
  • a flexible conveyor belt conveys filter plugs 26 separated by receiving spaces 24 along a course parallel with and beneath belt 10.
  • the garniture tape 54 travels through a trough called a garniture 23.
  • Garniture 23 is concave shaped. While garniture tape 54 travels through garniture 23, the garniture tape 54 assumes this concave shape. This concave shaped garniture tape accommodates the round shape of the axially aligned filter plugs 26 it conveys.
  • composition strap 21 portion of laminated belt 10 contacts the filter plugs 26. During this contact, the composition strap 21 urges the filter plugs 26 against garniture tape 54 thus holding plugs 26 in a stable position.
  • An independent device known in the art the synchronous drive, synchronizes the movement of laminated belt 10 with garniture tape 54 so that apertures 22 of belt 10 register with receiving spaces 24 between filter plugs 26.
  • An independent device known in the art, the charcoal chute, delivers free flowing material through apertures 22 into receiving spaces 24. Concurrently, the non-apertured portions 25 of belt 10 mask the filter plugs 26 from exposure to the free flowing material.
  • composition strap 21 of belt 10 acts to firmly position filter plugs 26 as they are conveyed at high speeds on garniture tape 54.
  • Such stable positioning maintains the accurate registry of apertures 22 with receiving spaces 24.
  • the stable positioning provided by belt 10 facilitates the accurate delivery of free flowing material into the receiving spaces 24 between filter plugs 26 as the plugs move at high speeds on garniture tape 54.
  • laminated belt 10 includes apertures 36 along both lateral edges of the belt.
  • Belt 10 travels around a plurality of wheels 50, each wheel including a row of radially extending teeth 52 positioned around its circumference.

  • laminated belt 10 travels around single end wheels 51 each with a parallel pair of radially extending teeth 52 positioned around its circumference.
  • the teeth 52 of wheels 51 engage with the apertures 36 of laminated belt 10.
  • apertures 22 extend through laminated belt 10 between the lateral rows of sprocket engaging apertures 36.
  • Apertures 22 serve as ports through which a standard device known,in the art delivers free flowing material to receiving spaces 24.
  • These embodiments may utilize forward facing louvers 37, represented in FIGS. 9, 10, and 11, positioned above apertures 22 in the middle of belt 10. These louvers 37 work to capture particulate matter like a scoop.
  • FIGS. 12 and 13 illustrate the parallel belts 40 with a pocket 41 suspended between them.
  • FIG. 14 illustrates the belt 40.
  • FIGS. 15 through 17 illustrate the relationship of the end sprockets 38 with a pocket 41.
  • FIG. 18 illustrates the pocket 41.
  • Belts 40 each travel around end sprockets 38 which provide drive, tension and position for belts 40.
  • Belts 40 may be standard industrial grade belts found on the market, such as the high torque drive belt 1890 14 M 55 made by T.B. Wood's Sons Co. These belts need not be specially fabricated. Two identical belts 40 may be created by simply cutting one high torque drive belt lengthwise.
  • These high torque drive belts include semicircular shaped projections 57 regularly spaced around the belt's inner surface 58.
  • a series of recesses 59 are evenly spaced around the outer circumference of the sprockets 38. These recesses 59 correspond with, accommodate and mate with the belt projections 57 as the belts 40 travel around and between the sprockets 38.
  • Free flowing material channelling devices called pockets 41 are suspended between the parallel belts 40. As the sprockets 38 turn, they drive the parallel belts 40 which in turn transport the pockets 41 suspended between them. Each pocket 41 includes one or more funnels 42 functioning to channel free flowing material.
  • the pockets 41 are fastened between belts 40 using steel pins 43 which extend completely through pockets 41 and belts 40. Each of the four corners 44 of pockets 41 are attached by a steel pin 43 to a belt 40. Pins 43 pass through belts 40 surrounded by bushing 45. Pins 43 then each pass through a roller 46 on the opposite side of belt 40.
  • the rollers 46 travel in part within a groove-like track 52.
  • This track 52 serves to contain the rollers and thus securely position the attached pockets 41.
  • pockets 41 directly communicate with and slide within positioning track 27 , an arrangement which further serves to position pockets 41.
  • This positioning track 27 terminates beneath the travel of the pockets 41 in a round shaped trough called a garniture 23.
  • a flexible garniture tape 54 travels through garniture 23 assuming the round shape of garniture 23.
  • the round shaped garniture 23 accommodates the round shape of the filter plugs 26 which travel through garniture 23 on garniture tape 54.
  • the garniture tape 54 transports filter plugs 26 in an axially aligned configuration, each plug separated by a,receiving space 24.
  • Parallel belts 40 travel in part parallel with the travel of garniture tape 54 such that the pockets 41 travel adjacent to the filter plugs 26 transported on garniture tape 54.
  • the pockets 41 contact the filter plugs 26 during this adjacent travel.
  • the under surface 55 of the pockets 41 terminates in a concave shape 55 to closely accommodate the round shape of filter plugs 26.
  • a known synchronous drive (not shown) synchronizes the travel of the belts 40 with the travel of the garniture tape 54. This synchrony ensures that funnels 42 of pockets 41 register with the receiving spaces 24 between the filter plugs 26, while pockets 41 and garniture tape 54 travel parallel with one another.
  • the registry of funnels 42 with receiving spaces 24 allows a known charcoal chute device (not shown) to deliver free flowing material through funnels 42 into receiving spaces 24.
  • the non-funnel portion 56 of pockets 41 act to mask the filter plugs from exposure to the free flowing material.
  • Belts 40 carry pockets 41 suspended at constant, non-variable intervals, facilitating the precise registration of the funnels 42 with the receiving spaces 24. This precise registration in turn facilitates the accurate delivery of free flowing material into the receiving spaces 24 between filter plugs 26 as the plugs move at high speeds on garniture tape 54.
