Abstract
Shredded tobacco is fed into and transported through a cigarette maker by a unit that includes at least one transport roller, driven in rotation about a longitudinal axis and equipped with a plurality of radial pins projecting radially from a peripheral surface, by which the flow of tobacco is taken up and directed along a predetermined feed path toward a unit that forms it ultimately into at least one continuous stream; the feed and transport unit is also equipped with at least one sensing device, offered to the peripheral surface of the roller and serving to detect any points where pins may be missing or damaged.
Description
- The present invention relates to a tobacco feed and transport unit in a machine for manufacturing tobacco products.
- The prior art embraces cigarette makers equipped with a feeding and conveying unit that comprises an infeed chamber from which shredded tobacco is taken up by a carding unit and directed into a descending duct or chute. At the bottom end of the chute, the tobacco is taken up by a toothed outfeed assembly and deposited on a conveyor belt that carries it toward the bottom inlet end of an ascending duct or chimney. The top end of the chimney coincides with the outfeed end of the tobacco feed and transport unit, and is enclosed by a conveyor consisting in a looped air-permeable aspirating belt such as will attract the tobacco, rising through the chimney as a continuous flow of distinct particles, and cause it to form progressively into a continuous stream.
- The stream of tobacco forming thus externally of the chimney is directed by the aspirating belt loop toward an ecreteur, or trimming station, of which the function is to reduce the stream of tobacco to prescribed and uniform cross sectional proportions. The trimmed tobacco stream is then released by the aspirating belt to the entry point of a station where a continuous cigarette rod is formed.
- The carding unit consists typically in a carding drum of which the surface of revolution presents a plurality of pins serving to take up and pick the shredded tobacco.
- In addition, the toothed outfeed assembly at the bottom end of the chute comprises a further carding roller and an impeller roller, both presenting a pinned surface of revolution.
- Finally, it is also the practice to use further rollers, structurally similar to those mentioned above, as a means of advancing the tobacco through the feed and transport unit.
- The interaction between the pins and the compact mass of tobacco can result in a partial breakage of the pins, or even in their complete detachment from the roller. Any fragmented or whole pins separated from the roller will find their way into the mass of tobacco and must then be removed by procedures familiar to a person skilled in the art.
- Moreover, the properties of tobacco transported by rollers with missing or damaged pins will be of a lower grade than those of tobacco transported by rollers with all pins intact, and this can affect the quality of the cigarettes ultimately.
- To verify possible degradation of the rollers in tobacco feed and transport units of conventional embodiment, the machine must be stripped down and the pins examined visually one by one to locate any that may be broken or missing. It follows that the cigarette maker must necessarily remain idle for an extended period while the inspection is conducted, and that production will be lost as a result.
- The object of the present invention is to provide a tobacco feed and transport unit in a machine for manufacturing tobacco products, such as will be unaffected by the aforementioned drawbacks.
- One object of the invention, in particular, is to provide a tobacco feed and transport system that will allow damaged or unseated carding pins to be located swiftly and easily.
- The stated object is realized according to the present invention in a tobacco feed and transport unit forming part of a machine for manufacturing tobacco products, comprising at least one transport roller set in rotation about a longitudinal axis, presenting a plurality of pins positioned on a peripheral surface of revolution and oriented radially away from the longitudinal axis, by which tobacco is taken up and caused to advance along a predetermined path toward a unit where it is formed into at least one continuous stream. In the device disclosed, a sensing device associated with the at least one transport roller serves to verify the presence and/or the integrity of the pins.
- The invention will now be described in detail, by way of example, with the aid of the accompanying drawings, in which:
-
FIG. 1 shows a portion of a cigarette maker, viewed schematically in perspective and cut away in part, comprising a tobacco feed and transport unit embodied according to the present invention; -
FIG. 2 shows a detail of the unit inFIG. 1 , viewed in perspective; -
FIG. 3 shows the detail ofFIG. 2 , enlarged and in a longitudinal section. - With reference to
FIG. 1 , which shows an infeed portion of a cigarette maker, the infeed portion is denoted 1 in its entirety and comprises a tobacco feed andtransport unit 2 serving to transform a mass of shredded tobacco into a continuous flow of tobacco particles. - The components of the feed and
transport unit 2 are housed in a vertically extendingenclosure 3 delimited uppermost by ahorizontal wall 4 and on either side by twovertical walls - The infeed
portion 1 presents aninlet duct 7 extending upward from thehorizontal wall 4, and below the duct, internally of theenclosure 3, a power driventoothed roller 8 by which theshredded tobacco 9 is directed down into alower chamber 10 delimited at the bottom by aconveyor belt 11. - The
chamber 10 accommodates a carding drum, or roller 12, rotatable about anaxis 12 a transverse to the twoside walls carding unit 13 and occupies a position adjacent to the downstream end of thebelt 11. - In addition to the carding roller 12, the
unit 13 comprises aproportioning roller 14 set in rotation substantially tangential to the carding roller 12 and in the same direction. - With this arrangement, the
shredded tobacco 9 is directed by thetoothed roller 8 onto thebelt 11 and then toward the carding roller 12, whereupon a layer of theshredded tobacco 9 substantially equal in thickness to the radial dimension of the carding teeth is transferred by the roller 12 away from thechamber 10 and beyond its position tangential to theproportioning roller 14. - Also associated with the
carding unit 13 is animpeller roller 15 rotatable about an axis parallel to theaxis 12 a of the carding roller 12, of which the function is to take up the layer oftobacco 3 from this same roller 12 and shower the constituent particles, in the direction denoted F1, down into a substantially vertical descending duct orchute 16 delimited by a pair oftransverse walls axis 12 a of the carding roller 12. - The bottom end of the
chute 16 is located facing the periphery of a take-up assembly 19 comprising a take-up roller 20, functioning also as a carding or picking roller, and animpeller roller 21 combining with the take-up roller 20 to transfer the shreddedtobacco 9 away from thechute 16. - The take-up roller 20 rotates about an
axis 20 a parallel to theaxis 12 a of the carding roller 12, and is designed to project thetobacco 9 in the form of distinct particles onto atransfer belt 22 moving from right to left as seen inFIG. 1 , and angled upward with the runout end located beneath the inlet of an ascending duct orchimney 23. - The
top outlet end 24 of thechimney 23 connects with aunit 25 by means of which to form at least onecontinuous stream 26 oftobacco 9, or in the case of a machine with two tobacco rod processing lines as in the example ofFIG. 1 , with aunit 25 forming two suchcontinuous streams 26. - The
stream 26 oftobacco 9 is advanced toward a garniture assembly, not illustrated, by which it will be formed into a continuous cigarette rod. - All the
aforementioned rollers unit 2 serving to feed and transport thetobacco 9 are typified by the same structure. Each one of therollers transport roller 27 and illustrated inFIGS. 2 and 3 , is rotatable about a relativelongitudinal axis 27 a and presents a plurality ofpins 28 occupying theperipheral surface 29. - The
pins 28 are oriented radially away from thelongitudinal axis 27 a of theroller 27, in such a way that thetobacco 9 will be taken up and carried along a predetermined path extending from theinlet duct 7 toward theunit 25 by which thestream 26 oftobacco 9 is formed. - Whilst the
rollers pins 28, hence their density, are selected on the basis of the type and condition of thetobacco 9 handled at each stage along the predetermined path. - To advantage, the feed and
transport unit 2 also comprises at least onesensing device 30 serving to verify the presence and/or integrity of thepins 28 associated with at least onetransport roller 27 of theunit 2. - Preferably, each of the
rollers FIG. 1 is equipped with arespective sensing device 30 serving to verify the integrity of therespective pins 28. To illustrate the structure of theunit 2 more clearly,FIG. 1 indicates onesuch sensing device 30 associated with the drum or roller 12 of thecarding unit 13, and anotherdevice 30 associated with the take-up roller 20. - The
pins 28 are fashioned in conventional manner from ferromagnetic material and, in a preferred embodiment, thesensing device 30 will comprise at least oneinductive sensor 31. Positioned in close proximity to thepins 28, theinductive sensor 31 is able to pick up the magnetic field generated by theselfsame pins 28 and to detect any change in the strength of the field occasioned by the absence or degradation of one or more pins. - With reference to
FIGS. 2 and 3 , which show thegeneric transport roller 27, thedevice 30 includes at least onesensing unit 32 presenting a plurality ofsensors 31 arrayed in closed order one alongside another and positioned facing thepins 28 of theroller 27. Thesensing unit 32 occupies a fixed position, and is placed so that thepins 28 will pass beneath thesensors 31 when theroller 27 is set in rotation. - In the case of an appreciably
long roller 27, thedevice 30 will incorporate a plurality ofsensing units 32 arrayed in closed order one beside another along the longitudinal dimension of theroller 27 and preferably staggered in the circumferential direction, as illustrated inFIG. 2 . - Each
sensing unit 32 extends partially around the circumference of therespective roller 27. - The
pins 28 are arranged typically in a plurality ofrows 28 a, each passing around the circumference of theroller 27. Therows 28 a ofpins 28 in turn are ordered one beside another along theaxis 27 a of theroller 27. - Advantageously, to enable an exact identification of the damaged or missing pin or
pins 28, each of thesensors 31 belonging to a givensensing unit 32 is placed over just one respectivecircumferential row 28 a, so as to maximize its sensitivity to the magnetic field generated by thepins 28 of the row in question. - Moreover, to ensure the magnetic effect induced by a
row 28 a ofpins 28 is suitably isolated from thesensor 31 monitoring anadjacent row 28 a, theface 33 of thesensing unit 32 directed toward thepins 28 will present a plurality ofgrooves 34, one for eachsensor 31, in which the tips presented by thepins 28 of therespective rows 28 a are freely insertable (FIG. 3 ) during the rotation of theroller 27. - In an alternative version of the
device 30, not illustrated in detail, thesensors 31 of asingle unit 32 are ordered in ranks lying parallel to theaxis 27 a of therespective roller 27, and columns extending transversely to theaxis 27 a. Each column ofsensors 28 coincides with arelative groove 34 in which a correspondingcircumferential row 28 a ofpins 28 is freely insertable during the rotation of the roller. - The
sensors 31 are connected to a processing unit (not illustrated) integrated, for example, into the master controller of the cigarette maker. The unit in question monitors the signals received from the sensors and, in the event of a break in continuity being detected, trips an alarm output signal that will also pilot the feed andtransport unit 2 to shut down automatically and indicate the position of the missing or damaged pin. - It thus remains only for the operator to replace the missing or damaged
pin 28, already identified by the machine, without the need to search through the multitude of pins presented by theroller 27. - The objects stated at the outset are realized in a unit according to the invention, and the problems associated with the prior art duly overcome, since the breakage of a pin can be detected in real time and the damaged or missing pin replaced swiftly, stopping the machine only for the time necessary to effect the replacement.
- Self-evidently, it will be preferable to fit the
sensing device 30 to all the rollers of the machine or, where there are cost constraints, at least to those rollers with the more slender pins.
