Definitions

  • This invention relates to an improved winnowlng device for cigarette machines of the type disclosed in the patent to Teale, No.
  • Fig. 1 is a sectional side elevation of a device constructed accordance with the invention and in operative position in an automatic feed mechanism for cigarette machines
  • Fig. 2 is a sectional elevation tak- ⁇ en in the line 2 2 in Fig. 1
  • Fig. 3 is a fragmentary side view of the winnowing device per se on an enlarged scale.
  • the invention consists of a combined picker and fan acting on a mass of shredded tobacco in the feed mechanism of a cigarette machine to disentangle the. tobacco and propel its shreds, and means for directing or guiding the shreds propelled by said picker and fan to cause them to be thrown through different trajectories to thus separate the desirable shreds from undesirable pieces of tobacco and foreign matter, in a simplified and more effective manner than heretofore.
  • the winnowing device is shown in position in an automatic feed mechanism for cigarette machines, where it is usually employed.
  • This mechanism is well known and consists, generally, of a hopper 4, a feed drum 5, a filling drum 6, a comb 7, a pressing belt 8, a forwarding'belt 9, a pressure roller 10, a filler roller 11, a picker roller 12, and a chute 13, all constructed and operating in a manner well known in the art and therefore needing no detailed description herein.
  • the winnowing device proper consists of a rapidly rotating shaft 14 adjacent the yfeed drum. 5, a combined picker and fan fast on said shaft and comprising fan blades 15 and picker pins 16 projecting from the edges of said blades, and means for directing the shreds propelled by said picker and fan to cause them to be thrown through different tiajectories tol thus separate the desirable s reds from undesirable pieces of tobacco and foreign matter, said means consisting of an adjustable concave 17 adjacent theperiphery of said picker and fan.
  • the shaft 14 derives its motion from one of the shafts of the cigarette machine in connection With which the device is used, not shown. And thepms 16 on each blade 15 are in staggered relationship with the pins of adjacent blades, 1n order to effect an improved picking or disentangling action on the mass of tobacco on the feed drum 5.
  • the blades l5 of the fan,'and also the pins 16 of the picker, are rearwardly inclined, so that they will be withdrawn from the shreds 1n the concave 17 at an angle which will re lease said shreds and not carry them up over the combined picker and fan.
  • the desirable lighter shreds will fall upon the forwarding belt 9, while the heavier and undesirable pieces of tobacco and4 foreign matter will be thrown into the receptacle 18.
  • This receptacle is in the form of a drawer which .may be withdrawn to remove its contents from time to time.
  • the shreds of tobacco lie more or less extended in many directions in the mass on the feed drum 5. As they approach .the combined picker and fan, some of them will be engaged by two or more picker pins 16, and others will come between adjacent picker pins. In the case of the former, the shreds will be thrown out of the concave 17 by the pins 16. In the case of the latter, however, a pin 16 may not enga e a shred at all, but when this occurs the s red is engaged by the outer edge of one of the fan blades 15 and is thereby thrown out of the concave. Pieces of foreign matter are usually too small to be engaged by'more thanone picker pin, and even then the pin may simply throw the same in between adjacent pins.
  • a winnowing device for cigarette machines the combination with a combined picker and fan acting on a mass of shredded tobacco to disentangle it and propel its shreds, of means for guiding the shreds propelled by said picker and Afan to cause them tobe thrown through diierent trajectories to thus separate the desirable shreds from undesirable pieces of tobacco and foreign matter.
  • a winnowing device for cigarette machines, the combination with a combined picker and fan acting on a mass of shredded tobacco to disentang-le it andL plropel its shreds, of means for guiding t e ⁇ shreds propelled by said picker and fan to cause them to be thrown through different trajectories to thus separate the desirable shreds from undesirablepieces of tobacco and forei matter, said fan having blades, and said picker consisting of pins projecting from the edges of said blades.
