Definitions

the invention relates to a device for separating the paper casing from defective filter cigarettes for the purpose of recovering the tobacco with a transport belt for feeding the cigarettes aligned approximately parallel to the conveying direction and at least one roller for opening the paper casings.
a device for recovering tobacco from defective cigarettes in which the cigarettes, which are aligned approximately parallel to the direction of transport, are fed to a roller system by means of a conveyor belt wetted with water, which has at least one slotted roller provided with rotating knife rings having.
This slitting roller either has several knife rings, which are arranged as closed individual rings at an acute angle to the axis of rotation of the roller, or is provided with a slitting knife running helically over the entire length of the roller. In this way it is ensured that the moistened paper wrappings of the cigarettes entering the roller system in axial alignment are gently burst without the long-fiber tobacco being damaged.
the invention has for its object to provide a device for cutting the paper casing of defective filter cigarettes of the type defined in the introduction, in which a moistening of the conveyor belt can be dispensed with and which is also suitable for recovering the tobacco from defective filter cigarettes.
the solution to this problem by the invention is characterized in that the roller is provided with a plurality of knife disks which are arranged at a distance from one another which is smaller than the diameter of the cigarettes and which are designed such that they form the strand part of the cigarette weaken so that it bursts, and that they only press in or perforate the filter cover paper so that it does not tear and as a result no acetate fibers are released from the filter.
the knives are provided with a plurality of teeth on their circumference and in that the drive of the roller is synchronized with the drive of the transport belt in such a way that the circumferential speed of the knife disks corresponds to the conveying speed of the transport belt.
the knife disks provided with a plurality of teeth on their circumference cause perforation of the paper casing of the filter cigarettes aligned in the transport direction.
the paper casing perforated by means of the device according to the invention can be burst open without difficulty, so that the tobacco can be completely recovered.
the firmer and more elastic sheathing of the filter of the filter cigarettes because of the filter mass is not destroyed by the cutter disks with a large number of teeth. Even if smaller holes are pressed into the filter casing, no filter components can get into the tobacco to be recovered.
the filters as a whole can therefore be removed from the device together with the separated paper cover.
the object set out above can also be achieved in that the roller is provided with a plurality of knife disks with a continuously circular, truncated cutting surface which are arranged at a distance from one another which is smaller than the diameter of the cigarettes, and that the drive of the roller is synchronized with the drive of the conveyor belt in such a way that the peripheral speed of the cutter disks is greater than the conveyor speed of the conveyor belt.
the knife disks must be blunted to such an extent that the resulting printing area is sufficient to only press the filter together with cover paper, but that it is not large enough to prevent cutting or weakening of the cigarette paper on the cigarette rod.
the paper sleeve is weakened or cut open by means of the knife disks rotating at a higher peripheral speed than the conveying speed of the conveyor belt, without the firmer and more elastic coating of the filters being separated because of the filter material.
the paper sleeve is weakened or cut open by means of the knife disks rotating at a higher peripheral speed than the conveying speed of the conveyor belt, without the firmer and more elastic coating of the filters being separated because of the filter material.
no filter components can get into the tobacco to be recovered, because even finer cuts in the filter casing do not result in destruction of the filter leading to disruptive filter components.
the toothed knife disks can be held according to a further feature of the invention by spacer rings on the roller, whose outer diameter is only slightly smaller than the outer diameter of the toothed knife disks, so that the outer surface of the spacer rings together with the conveyor belt as a conveyor drive on the cigarettes works. This prevents any slippage between the cigarettes lying on the conveyor belt and the roller provided with the knife disks, which could damage the filters.
the teeth of the knife disks can be designed with a narrow head surface acting as a pressure surface on the envelope of the filter.
an upper belt interacting with the transport belt or another roller is arranged in front of the roller carrying the cutter disks. This not only maintains the longitudinal orientation of the cigarettes, but also results in a targeted and driven insertion of the cigarettes into the roller equipped with knife disks.
the distance between the upper belt or the pressure roller is smaller than the diameter of the cigarettes, the cigarettes flatten.
This not only specifies a defined cutting plane for the knife disks, it also results in an increase in the tension in the paper wrapping, which promotes separation, and a widening of the contact surface of the paper wrapper for the knife disks, so that the reliability of the separation of the paper wrapper is increased.
the invention provides a device for separating the paper envelope from defective filter cigarettes for the purpose of recovering the tobacco, which not only prevents Filter components get into the recovered tobacco, but also leaves the valuable long-fiber tobacco parts undamaged and also prevents the formation of shredded paper.
a rotary conveyor 1 can be seen, which the faulty filter cigarettes leave in the direction of the arrow shown.
the filter cigarettes reach the upper run of a conveyor belt 3 running between two belt rollers 2.
This conveyor belt 3 transports the filter cigarettes aligned parallel to the transport direction to a knife roller 4 which is driven synchronously with the conveyor belt 3.
a squeeze roller 5 is arranged behind the knife roller 4 in the transport direction of the filter cigarettes.
an upper belt 6 cooperating with the transport belt 3 is arranged, through which the filter cigarettes are fed to the knife roller 4 with the same orientation, to bridge the distance between the rotary conveyor 1 and the knife roller 4 2, a pressure roller 7 is used.
the knife roller 4 consists of a driven axis, on which a plurality of knife disks 8 are attached, which are kept apart by spacer rings 9. This distance between the knife disks 8 is smaller than the diameter of the cigarettes. With a cigarette diameter of 8 mm, the distance between the knife disks 8 is preferably 5 mm, so that each cigarette transported on the conveyor belt 3 into the knife roller 4 is reliably detected.
the knife disks 8 can be provided with a continuously circular cutting surface.
the drive of the knife roller 4 is synchronized with the drive of the conveyor belt 3 in such a way that the peripheral speed of the cutter discs 8 is greater than the conveying speed of the conveyor belt 3.
the paper casings of the filter cigarettes are reliably also separated from the smooth circumference of the cutter disks 8 due to the higher peripheral speed of the cutter disks 8. Since the wrapping of the filters is thicker and made of tougher paper than the paper wrapper for the tobacco and since the filter cigarettes are more flexible in the area of the filter than in the area of the paper wrapper filled with tobacco, the filters give in under the influence of the rotating smooth-walled knife disks 8, without being damaged in such a way that filter particles are formed.
knife disks 8 are used, which have a circumference according to FIGS. 3 and 4
a plurality of teeth 10 are provided.
these teeth 10 are designed with a narrow head surface acting as a pressure surface.
the thinner and less elastic paper that envelops the tobacco of the filter cigarette is perforated or cut, but not the mostly two-layer coating of the filter, since this increases the pressure surfaces of the teeth due to their higher strength and the greater elasticity of the filter 10 evades, so that damage to the filter can be avoided.
the outer diameter of the spacer rings 9 is only slightly smaller than the outer diameter of the cutter disks 8 provided with teeth 10. As a result, the outer surface of the spacer rings 9 interacts with the conveyor belt 3 in the manner of a conveyor drive. It is avoided that cigarettes are in any way between the Clamp cutter disks 8 and stay behind, so that undesirable damage to the filter can also be excluded.
the squeeze roller 5 arranged behind the knife roller 4 in the transport direction ensures that only perforated paper sleeves burst open by the knife roller 4, so that the tobacco contained in the cigarettes is completely emptied.
the upper belt arranged in the transport direction in front of the knife roller 4 or the pressure roller 7 provided in its place not only effect a targeted supply of the filter cigarettes to the knife roller 4, but can also flatten the respectively supplied filter cigarettes with a corresponding adjustment of the distance to the transport belt 3, thereby defining a defined one Cutting plane for the knife rollers 8 results and the tension in the paper wrapping to be separated is increased so that these burst almost automatically even when weakened, for example by perforation.
