The device comprises detecting means (52-53) located in the path (31) adjacent the cigarette conveyor for detecting shredded tobacco pieces accumulated in the path, whereby if shredded tobacco pieces begin to accumulate in the path, then the feeding device is immediately stopped (49-50) in response to a detection signal received from the detecting means.
Description
- The invention relates to a shredded tobacco feeding device for a cigarette making machine which is not damaged or broken at all even if it is jammed by shredded tobacco fed by the shredded tobacco feeding device.
- Such a machine, for example, as illustrated in Fig. 1 is conventionally known as a cigarette making machine. Referring to Fig. 1,
reference numeral 1 designates a feeding device, 2 a chimney, 3 a perforated cigarette conveyor, 4 a trimming device, 5 a cloth tape, 6 roll paper, 7 a pasting device, 8 a heater, 9 a density detector, and 10 a cutter. - In the cigarette making machine, shredded tobacco is sucked into and moved up within the
chimney 2 of thefeeding device 1 and is attracted to a lower portion of the perforatedcigarette conveyor 3 to form a layer of the shredded tobacco. The layer of the shredded tobacco is fed leftwardly as seen in Fig. 1 and is adjusted to have a suitable thickness by the trimming device 4 whereafter it is transferred onto the roll paper 6 placed on thecloth tape 5 and is wrapped in the same. The shredded tobacco is then pasted and is dried by theheater 8 to thus make a cigarette in the form of a bar. The bar-like cigarette thus formed is passed through thedensity detector 9 in order to measure the density of the cigarette whereafter it is cut into several cigarettes by thecutter 10. The cigarettes thus cut are then transferred onto and transported by a conveyor (not shown). During such transporation, non-confirming cigarettes are removed from the conveyor by means of a magnet valve (not shown) located midway of the transporting path so that only conforming cigarettes may be loaded onto trays (not shown). - During running of the cigarette making machine, if shredded tobacco having a high density is fed in the form of a dumpling or block from the feeding device or if foreign articles such as filter plug pieces are mixed in shredded tobacco, then the shredded tobacco may first accumulate in the neighbourhood of the trimming device 4, and then, after passing a flapper (not shown), the shredded tobacco may gradually accumulate in the
chimney 2 from the top of the same. - Where the production capacity of the cigarette making machine is about 2000 units per minute or so, even if the machine is stopped after an operator finds that something is wrong with the machine, the
chimney 2 will not be filled with shredded tobacco and hence no serious problem will occur. However, since various improvements have been made in recent years to an extent to enable production of up to 8000 cigarettes per minute, if accumulation of shredded tobacco or jamming of the machine should once occur, such accumulation would progress in a short period of time to fill thechimney 2 with shredded tobacco. If thechimney 2 is thus filled with shredded tobacco, then shredded tobacco will accumulate also to a picker winnower (not shown) installed adjacent a lower end of thechimney 2. As a result, a drum (not shown) will be acted upon by a heavy load to cause a trouble in the machine while the shredded tobacco will be compressed into a block like a wood, which will cause a trouble to damage several portions of thefeeding device 1. - The present invention has been made in consideration of such circumstances as described above, and it is an object of the invention to provide a shredded tobacco feeding device for a cigarette making machine wherein, when jamming occurs, operation is immediately stopped to prevent a trouble of and damage to the machine.
- In order to attain this object, according to the present invention, a shredded tobacco feeding device for use with a cigarette making device for feeding shredded tobacco pieces produced from shredded tobacco and having a size sufficient to allow the shredded tobacco pieces to be wrapped in roll paper to a cigarette-conveyor of the cigarette making machine is characterized in that detecting means for detecting that shredded tobacco pieces accumulate in a path for feeding shredded tobacco pieces having a size sufficient to allow the shredded tobacco pieces to be wrapped in roll paper to the cigarette conveyor is provided at a position of the path adjacent the cigarette conveyor such that the feeding device may be stopped in response to an accumulation detection signal outputted from the detecting means.
- Now, an embodiment of the present invention will be described with reference to the accompanying drawings.
- Fig. 1 is a front elevational view generally showing a conventional cigarette making machine;
- Fig. 2 is a cross sectional view, in schematic representation, of a shredded tobacco feeding device according to an embodiment of the present invention;
- Fig. 3 is an enlarged partial view of the shredded tobacco feeding device of Fig. 2;
- Fig. 4 is a perspective view,in schematic representation, illustrating a power transmitting mechanism;
- Fig. 5 is a schematic view illustrating an arrangement of a cigarette conveyor and associated components; and
- Figs. 6a, 6b, 6c and 6d are diagrammatic representations illustrating operations of a photoelectric detector.
- Referring to Fig. 2 which is a cross sectional view illustrating, in schematic representation, an embodiment of a shredded tobacco feeding device according to the present invention, shredded tobacco is thrown into a
storage tank 14 in most cases by air. The quantity to be contained in thestorage tank 14 is determined in accordance with the height of aphotoelectric tube 15. In particular, if the top face of shredded tobacco becomes positioned lower than the position of thephotoelectric tube 15, then shredded tobacco is additionally thrown into thestorage tank 14. Shredded tobacco within thestorage tank 14 is lifted by aneedle belt 16 and only that shredded tobacco which exists among needles of thebelt 16 is allowed to pass by ascraping roller 17 which scrapes excessive shredded tobacco off theneedle belt 16 so as to establish a predetermined fixed relationship between the speed of theneedle belt 16 and the quantity of passing shredded tobacco. The shredded tobacco which has passed by thescraping roller 17 is scraped off theneedle belt 16 by ablade 18 and drops into ashred pool 19. Shreds which have been removed by a trimming device 4 (refer to Fig. 5) and transported by avibrating belt 20 is also dropped into theshred pool 19 and joined to the shredded tobacco which has been fed by theneedle belt 16. - The shredded tobacco in the
shred pool 19 is carried upwardly by needles implanted to afirst drum 21. A bar-like shred 23 is formed by and between thefirst drum 21 and asecond drum 22 which rotates in a direction to prevent shredded tobacco from passing through a gap between the first andsecond drums like shreds 23 to always remain identical, when shredded tobacco is detected by aphotoelectric tube 24, the speed of theneedle belt 16 is reduced, and on the contrary when shredded tobacco is not detected by thephotoelectric tube 24, the speed of theneedle bed 16 is increased. As a result, the quantity of shredded tobacco which passes through the gap between the first andsecond drums - The shredded tobacco which has passed through the gap between the first and
second drums picker 25 into pieces which have a size suitable for wrapping in roll paper. The shredded tobacco is then accelerated to be discharged by awinnower 26. - Such pieces of shredded tobacco thus discharged is attracted, where they are light in weight, to an attracting
roller 30 by air which is blown out fromholes 29 after the air has been fed under pressure from aduct 27 and changed into uniform air flows by aflow regulating plate 28. The light pieces of shredded tobacco are then lifted within achimney 31 and are layered on a perforated cigarette conveyor 3 (refer to Fig. 5). On the other hand, heavy pieces of shredded tobacco advance straightforwards as illustrated in detail in Fig. 3 and are thrown out into achannel 33 by a throwing outdrum 32. Anair window 34 is located at a lower portion of thechannel 33, and since air is flown upwards in thechannel 33, only heavy pieces, that is, stems existing among shredded tobacco are allowed to drop onto aperforated roller 35. - The
perforated roller 35 has a great number of perforations formed therein for classifying stems thus separated from among the shredded tobacco. Those stems which can be received in the perforations of theperforated roller 35 are regarded as allowable stems and are returned to the flow of shreds by way of anotherchannel 36. Stems which cannot be received in the perforations are scraped off by abrush roller 37 and are carried away by means of an air feeding 38 pipe (refer to Fig. 2). - Fig. 4 illustrates a power transmission mechanism. The entire cigarette making machine is installed on a
bed 39. Rotation of amain motor 40 is transmitted to amain shaft 44 by way ofpulleys further pulleys - A
brake 48 is provided on ashaft 47 for thepulley 42 in order to stop running of the machine in a short period of time. - The
pulley 46 provides a power inputting means to the feeding means A, and rotation of thepulley 46 is transmitted to rotationally drive, via an electromagnetic coupling 49 (refer to Fig. 2) and a shaft (not shown), the above describedneedle belt 16, the scraping offroller 17, theblade 18, the first andsecond drums perforated roller 35 and so on. - During normal running of the machine, a voltage is applied to the
electromagnetic coupling 49 to transmit rotation of thepulley 46 to the shaft. Anelectromagnetic brake 50 is coupled to the shaft. During normal running, theelectromagnetic brake 50 remains inoperative. - A
photoelectric detector 52 of the reflective type is located adjacent an exit of the chimney 31 (that is, at a location in the neighbourhood of thecigarette conveyor 5 and adjacent a flapper 51) as seen in Figs. 2 and 5. - The
photoelectric detector 52 is operable to irradiate light to an inner wall face 31a so as to go across shredded tobacco moving upwardly in an air flow within thechimney 31 and to receive the light reflected from the inner wall face 31a as illustrated in Fig. 6a for detecting presence or absence of jamming or accumulation. If jamming by shredded tobacco occurs, such reflected light is not received by thephotoelectric detector 52, for example, as seen in Fig. 6b, and an output of thephotoelectric detector 52 thus presents a corresponding change. - Output of the
photoelectric detector 52 is inputted to a jammingdiscriminating circuit 53 which effects predetermined signal processing. If the jammingdiscriminating circuit 53 detects jamming from an output of thephotoelectric detector 52, it outputs a control signal to stop voltage application to theelectromagnetic coupling 49 and to initiate voltage application to theelectromagnetic brake 50. - It is to be noted that where the
photoelectric detector 52 employed is otherwise of the penetrating type, a light source 52a may be disposed in opposing relationship to thephotoelectric detector 52 as seen in Fig. 6c such that light may be irradiated across shredded tobacco moving up within thechimney 31 to thephotoelectric detector 52. Thus, if jamming by shredded tobacco occurs, light is not received by thephotoelectric detector 52, for example, as shown in Fig. 6d, and hence an output of thephotoelectric detector 52 presents a corresponding change. - Operations of the embodiment as described above will now be described.
- Pieces of shredded tobacco produced in such a way as described hereinabove and having a size suitable to wrap in roll paper 6 are attracted in a layer from the
chimney 31 to a lower part of the perforatedcigarette conveyor 3 located below asuction chamber 54. The shredded tobacco pieces thus attracted in a layer is carried leftwardly as in Fig. 5. Thereupon, the flapper prevents atmospheric air from being introduced into thechimney 31 to disturb the layer of the shredded tobacco pieces. - The layer of the shredded tobacco pieces is then transported by the
cigarette conveyor 3 and is adjusted into a suitable thickness by the trimming device 4 while excessive shredded tobacco pieces are fed back to theshred pool 19 by means of the vibratingconveyor 20. - The shredded tobacco pieces thus transported are then transferred onto roll paper 6 placed on a
cloth tape 5 and are wrapped in the roll paper 6 and compressed to have a circular cross section. - During such running,if shredded tobacco having a high density, for example, in the form of a dumpling or block, is fed or if foreign articles such as filter plug pieces are mixed among shredded tobacco, shredded tobacco pieces will first accumulate in the neighbourhood of the trimming device 4, and then such accumulation will proceed to the
flapper 51, and finally shredded tobacco pieces will accumulate in thechimney 31 beginning from the top thereof. - After such accumulation of shredded tobacco begins, an output of the
photoelectric detector 21 will exhibit a change so that thejamming discriminating circuit 53 will provide a control signal to disengage theelectromagnetic coupling 49 to interrupt transmission of rotation of thepulley 46 to the shaft. Meanwhile, theelectromagnetic brake 50 will operate to stop rotation of the shaft. - As a result, rotation of the
needle belt 16, the scraping offroller 17, theblade 18, thedrums chimney 31. Accordingly, a trouble of and damage to the machine caused by jamming of thechimney 31 can be eliminated. - It is to be noted that since the feeding device A normally has only a low inertia, even if the
electromagnetic brake 50 is omitted, a trouble of and damage to the machine to be caused by shredded tobacco stuffed in thechimney 31 can be similarly prevented although there may be some delay of time. - It is also to be noted that the feeding device A is not limited to that of the embodiment, and various types may be employed therefor.
- As apparent from the foregoing description, in a shredded tobacco feeding device according to the present invention, detecting means (
photoelectric detector 52, jamming discriminating circuit 53) for detecting that shredded tobacco pieces accumulate in a path (chimney 31) for feeding shredded tobacco pieces of a size sufficient to allow the shredded tobacco pieces to be wrapped in roll paper to a cigarette conveyor is provided at a position of the path adjacent the cigarette conveyor such that the feeding device may be stopped in response to an accumulation detection signal outputted from the detecting means. Accordingly, if shredded tobacco begins to accumulate, the feeding device can be stopped immediately. And hence, even if the production capacity of cigarettes is improved, a trouble of and damage to the machine arising from accumulation of shredded tobacco can be eliminated.
