Abstract
Description
- 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).
- Several devices in the prior art which insert free flowing material between filter plugs utilize belts. For example, 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.
- Likewise, 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.
- Likewise, 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.
- Several devices in the prior art, including one described in U.S. 3,623,404, include a belt or chain consisting of an endless series of links. In such devices, each link is connected to the preceding and following links forming an endless chain. The chain travels around a plurality of wheels or sprockets which provide the chain with drive, tension and position. The chain travels in part parallel with and. adjacent to a garniture tape transporting a series of axially aligned filter plugs separated by spaces.
- The links comprising such chains contain channels or funnels capable of channelling particulate matter. As the chain and the garniture tape travel parallel with one another, the links travel adjacent to the axially aligned filter plugs. During this adjacent travel, 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. However, 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.
- It has been desired to provide a laminated belt for use in a device which delivers free flowing material into receiving spaces between filter plugs.
- It has further been desired to deliver free flowing material accurately into receiving spaces between filter plugs travelling at high speeds on a garniture tape.
- It has also been desired to protect the filter plugs from exposure to the free flowing 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. .During their parallel travel, 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. Likewise, the blank portions of the belt register with the filter plugs, screening the filter plugs from exposure to the free flowing material. By urging the plugs against the garniture tape, the laminated belt holds the plugs securely in this registered configuration. A device known in the art, the charcoal chute, delivers particulate matter through the apertures in the belt into the receiving spaces separating the plugs.
- By securely holding the filter plugs against the garniture tape, 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.
- It has also been desired to deliver free flowing material accurately into receiving spaces in separating axially aligned filter plugs, as the plugs travel at high speed on a garniture tape.
- It has further been desired to provide a device including parallel belts with pockets suspended between them, for delivering free flowing material into receiving spaces between filter plugs.
- In another embodiment, 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.
- In accordance with a first aspect of the present invention, there is provided 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.
- Preferably, according to a first embodiment of the first aspect of the invention, 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.
- In a preferred form, according to a second embodiment of the first aspect of the invention, 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.
- In accordance with a second aspect of the present invention there is provided 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.
- Preferably, 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.
- In accordance with a third aspect of the present invention there is provided apparatus for inserting free flowing material into receiving spaces between filter plugs for use in constructing cigarette filters, comprising two continuous parallel belts travelling around and between a plurality of sprockets with individual pockets suspended between the belts, said pockets including funnels to receive and channel free flowing material, the belts travelling in part parallel with and adjacent to a garnaiture tape carrying the filter plugs, while the funnels in the pockets channel free flowing material into the receiving spaces between the filter plugs.
- Preferably, the under-surface of the pockets contacts the filter plugs as the belts carry the pockets parallel with and adjacent to the garniture tape, said under-surface terminating in a concave shape to accommodate the round shape of the filter plugs. More preferably, the parallel belts move in synchrony with the garniture tape so that the funnels in the pockets register with the receiving spaces between the filter plugs delivered by the garniture tape.

- FIG.18 is a perspective view of the pocket of FIGS. 12, 13, 15-17.
- Referring to the drawings, FIGS. 1 through 6 illustrate the laminated belt designated generally by
reference numeral 10.Laminated belt 10 travels around a plurality of wheels, including adrive wheel 11 and anidler wheel 12.Motor 15 powers drivewheel 11 which in turn applies power to movebelt 10.Idler wheel 12 provides tension and position forlaminated belt 10. -
Laminated belt 10 is a lamination ofmetal band 20 and acomposition strap 21.Metal band 20 engages directly withwheels Composition strap 21 is laminated onto the side ofmetal band 20 opposite the wheels.Composition strap 21 may be formed of neoprene or other suitable composition materials. Theneoprene composition strap 21 is molded from liquid neoprene,-which directly bonds to themetal band 20 without the need for adhesive. Thecomposition strap 21 terminates in aconcave shape 53. Thisconcave shape 53 closely conforms to the round shape of filter plugs 26 in the partially constructed cigarette filters.Apertures 22 extend through both themetal band 20 andcomposition strap 21 portions ofbelt 10. - A flexible conveyor belt, the
garniture tape 54, conveys filter plugs 26 separated by receivingspaces 24 along a course parallel with and beneathbelt 10. Thegarniture tape 54 travels through a trough called agarniture 23.Garniture 23 is concave shaped. Whilegarniture tape 54 travels throughgarniture 23, thegarniture tape 54 assumes this concave shape. This concave shaped garniture tape accommodates the round shape of the axially aligned filter plugs 26 it conveys. - During the parallel travel of
garniture tape 54 with thelaminated belt 10, thecomposition strap 21 portion oflaminated belt 10 contacts the filter plugs 26. During this contact, thecomposition strap 21 urges the filter plugs 26 againstgarniture tape 54 thus holdingplugs 26 in a stable position. - An independent device known in the art, the synchronous drive, synchronizes the movement of
laminated belt 10 withgarniture tape 54 so thatapertures 22 ofbelt 10 register with receivingspaces 24 between filter plugs 26. An independent device known in the art, the charcoal chute, delivers free flowing material throughapertures 22 into receivingspaces 24. Concurrently, thenon-apertured portions 25 ofbelt 10 mask the filter plugs 26 from exposure to the free flowing material. - By urging filter plugs 26 against
garniture tape 54,composition strap 21 ofbelt 10 acts to firmly position filter plugs 26 as they are conveyed at high speeds ongarniture tape 54. Such stable positioning maintains the accurate registry ofapertures 22 with receivingspaces 24. Thus the stable positioning provided bybelt 10 facilitates the accurate delivery of free flowing material into the receivingspaces 24 between filter plugs 26 as the plugs move at high speeds ongarniture tape 54. - In one alternative embodiment represented in FIG. 7,
laminated belt 10 includesapertures 36 along both lateral edges of the belt.Belt 10 travels around a plurality ofwheels 50, each wheel including a row of radially extendingteeth 52 positioned around its circumference. Theteeth 52 ofwheels 50 engage with theapertures 36 oflaminated belt 10. In a similar alternative embodiment represented in FIG. 8,laminated belt 10 travels aroundsingle end wheels 51 each with a parallel pair of radially extendingteeth 52 positioned around its circumference. Theteeth 52 ofwheels 51 engage with theapertures 36 oflaminated belt 10. - In the embodiments represented in FIGS. 7 and 8,
apertures 22 extend throughlaminated belt 10 between the lateral rows ofsprocket engaging apertures 36.Apertures 22 serve as ports through which a standard device known,in the art delivers free flowing material to receivingspaces 24. These embodiments may utilize forward facinglouvers 37, represented in FIGS. 9, 10, and 11, positioned aboveapertures 22 in the middle ofbelt 10. Theselouvers 37 work to capture particulate matter like a scoop. - Referring to the drawings of the second embodiment, FIGS. 12 and 13 illustrate the
parallel belts 40 with apocket 41 suspended between them. FIG. 14 illustrates thebelt 40. FIGS. 15 through 17 illustrate the relationship of theend sprockets 38 with apocket 41. FIG. 18 illustrates thepocket 41. -
Belts 40 each travel aroundend sprockets 38 which provide drive, tension and position forbelts 40.Belts 40 may be standard industrial grade belts found on the market, such as the high torque drive belt l890 14M 55 made by T.B. Wood's Sons Co. These belts need not be specially fabricated. Twoidentical 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'sinner surface 58. A series ofrecesses 59 are evenly spaced around the outer circumference of thesprockets 38. Theserecesses 59 correspond with, accommodate and mate with thebelt projections 57 as thebelts 40 travel around and between thesprockets 38. - Free flowing material channelling devices called
pockets 41 are suspended between theparallel belts 40. As thesprockets 38 turn, they drive theparallel belts 40 which in turn transport thepockets 41 suspended between them. Eachpocket 41 includes one ormore funnels 42 functioning to channel free flowing material. Thepockets 41 are fastened betweenbelts 40 usingsteel pins 43 which extend completely throughpockets 41 andbelts 40. Each of the fourcorners 44 ofpockets 41 are attached by asteel pin 43 to abelt 40.Pins 43 pass throughbelts 40 surrounded by bushing 45.Pins 43 then each pass through aroller 46 on the opposite side ofbelt 40. - As the belts travel around the end sprockets, the
rollers 46 travel in part within a groove-like track 52. Thistrack 52 serves to contain the rollers and thus securely position the attached pockets 41. Also, pockets 41 directly communicate with and slide withinpositioning track 27 , an arrangement which further serves to position pockets 41. Thispositioning track 27 terminates beneath the travel of thepockets 41 in a round shaped trough called agarniture 23. Aflexible garniture tape 54 travels throughgarniture 23 assuming the round shape ofgarniture 23. The round shapedgarniture 23 accommodates the round shape of the filter plugs 26 which travel throughgarniture 23 ongarniture tape 54. - The
garniture tape 54 transports filter plugs 26 in an axially aligned configuration, each plug separated by a,receivingspace 24.Parallel belts 40 travel in part parallel with the travel ofgarniture tape 54 such that thepockets 41 travel adjacent to the filter plugs 26 transported ongarniture tape 54. Thepockets 41 contact the filter plugs 26 during this adjacent travel. The undersurface 55 of thepockets 41 terminates in aconcave 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 thegarniture tape 54. This synchrony ensures that funnels 42 ofpockets 41 register with the receivingspaces 24 between the filter plugs 26, whilepockets 41 andgarniture tape 54 travel parallel with one another. The registry offunnels 42 with receivingspaces 24 allows a known charcoal chute device (not shown) to deliver free flowing material throughfunnels 42 into receivingspaces 24. Thenon-funnel portion 56 ofpockets 41 act to mask the filter plugs from exposure to the free flowing material. -
Belts 40 carrypockets 41 suspended at constant, non-variable intervals, facilitating the precise registration of thefunnels 42 with the receivingspaces 24. This precise registration in turn facilitates the accurate delivery of free flowing material into the receivingspaces 24 between filter plugs 26 as the plugs move at high speeds ongarniture tape 54. - One skilled in the art will appreciate that the present invention can be practiced by other than the described embodiments, which are presented for purposes of illustration and not of limitation and the present invention is limited only by the claims which follow.
