Abstract
In a filter tip attachment machine, filter rods (2) are taken up from a hopper by a roller (5) furnished with longitudinal flutes (7), each accommodating one rod (2) and operating in conjunction with one or more rotating disc cutters (11) by which the rods (2) are divided into two or more plugs (10); the flutes (7) are sectional, incorporated into a set of axially slidable modules (17, 20, 23) ensheathing the take-up roller (5) and adjustable for position along the rolling surface according to the number of plugs (10) that will be cut from the rod (2), or to the length of the single plug (10), or both.
Description
- The present invention relates to a device for feeding filter rods in a filter tip attachment machine.
- The term filter rod is used to describe a stick of filter material, prepared to a predetermined length and subjected to a cross-cutting step from which two or three filter plugs are obtained, each twice the length of a single tip destined ultimately to form part of one filter cigarette.
- More particularly, the present invention relates to a roller by which single filter rods are taken up from the bottom of a feed hopper.
- The outer cylindrical surface of the take-up roller coincides with the bottom of the hopper and is furnished with a plurality of aspirating flutes positioned to receive the single filter rods, in such a way that when the roller is set in rotation, the rods can be transferred away from the hopper and directed through one or more cutting stations where they are divided into plugs, thence toward a station where they are transferred to a further roller.
- The single flutes function primarily as elements by means of which to retain the single filter rods, but also as steadying elements with which one or more disc cutters, rotating about respective axes parallel to the axis of rotation of the take-up roller, are able to interact during the cutting step.
- More exactly, the cutter or cutters operating at one or more relative stations will pass through respective radial gaps afforded by the take-up roller, extending transversely to each flute, in such a way as to slice likewise transversely through the filter rod.
- Where the intention is to obtain two plugs from a single filter rod, there will be just one disc cutter operating on the path followed by the flutes between the take-up area and the point of transfer to the next roller, and the flutes themselves will present a single gap, positioned intermediately to coincide with the area where the cutting edge of the disc passes through the rod.
- If the intention, on the other hand, is to obtain three plugs of equal length from a single filter rod, there will be two disc cutters operating along the path followed by the flutes between the take-up area and the point of transfer to the next roller, distanced one from the other along a direction parallel with the axis of the take-up roller.
- Accordingly, the flutes will present two mutually parallel gaps placed to coincide with the areas where the cutting edges of the discs pass through the rod.
- In the light of the foregoing, it follows that if a filter tip attachment machine has been set up to divide filter rods into two plugs, for example, then in the event of production requirements dictating subsequently that the rods be divided into three plugs rather than two, not only will the number of disc cutters need to be altered, but the take-up roller itself must also be changed.
- Again, it will be evident that the take-up roller must be replaced, still assuming a situation where plugs are cut from each filter rod, in the event of production requirements dictating a change in the length of the filter tip. In effect, it is the length of the filter plug that determines the distance separating the cutters, hence the distance between the relative gaps, and accordingly, if the size of the filter tip is altered, then not only will the distance between the cutters need to be adjusted, but the take-up roller must be changed as well.
- The object of the present invention is to set forth a device for feeding filter rods in a filter tip attachment machine, such as will allow of overcoming the drawbacks mentioned above.
- The stated object is realized in a device for feeding filter rods in a filter tip attachment machine, as recited in
