Definitions

  • the invention relates to a longitudinal conveyor for products of the tobacco processing industry having the features of the preamble of claim 1.
  • Longitudinal conveyors of the generic type are commonly used in manufacturing machines in which the products, such as e.g. Tobacco sticks or filter sticks are supplied in a continuously produced strand in the longitudinal direction, and then transported further cut to a predetermined length.
  • the continuously fed strand is transported by means of a driven format strip in the longitudinal direction of the strand and fed to a cutting device in which the products are cut off from the strand by a predetermined length. After cutting, the cut products are strung together into bars in a prism rail, the bars being pushed by the transporting motion of the strand fed continuously in front of the cutter.
  • a circulating conveyor further, also referred to as a spider, carried away.
  • the further conveyor is formed by a drum rotating about an axis of rotation, and has on the end face of the drum parallel to the axis of rotation protruding lifting arms, at the ends of which
  • CONFIRMATION COPY are provided to the axis of rotation and parallel to the supplied products aligned wells.
  • the troughs are provided with openings which are fluidically connected to a pressure medium system of the longitudinal conveyor and can be acted upon by the pressure medium system with negative pressure.
  • the products must be conveyed away from the longitudinal axial conveyor with a higher speed in relation to the speed of the cut products fed, also referred to as overspeed.
  • the overspeeding to be selected depends inter alia on the length of the cut products, and in such a way that the overspeed must always be higher for shorter products than for longer products. This has the disadvantage that when changing the product to products with a different length and the overspeed must be adjusted.
  • the object of the invention is to provide a longitudinal conveyor of the type mentioned, with the products of different lengths with improved process reliability can be conveyed.
  • a conveyor belt is provided, which is arranged between the cutting device and the further conveyor, and with which the products after cutting by the cutter at a second speed are fed to the further conveyor, wherein the second speed is greater than the first speed.
  • the proposed solution provides several advantages with respect to the longitudinal conveyor.
  • the transport movement of the cut products from the feeding movement of the endless strand decoupled so that the cut products do not necessarily have to be transported under immediate conditioning. Rather, the cut products are actively removed from the cutter and fed to the conveyor. Thereby, the risk of damming of the products or the emergence of the so-called strand flutter can be reduced.
  • the required overspeed of the further conveyor can then be reduced, which in turn means that one and the same further conveyor can be used for a wider range of lengths of the products to be conveyed.
  • Conveyor belt is particularly well suited as a transport device, since the products only need to be placed on the conveyor belt and are automatically taken by the frictional forces of the conveyor belt.
  • the frictional forces can be influenced by a specific choice of the surface condition of the conveyor belt.
  • Transport device of the cutting device to the conveyor further be transported over a longer distance continuously.
  • the products can be accelerated over a longer distance to the higher second speed, so that the maximum-acting acceleration and the resulting acceleration are achieved. hanging on the products acting forces are lower in height.
  • the conveyor belt extends at least almost over the entire to be bridged by the cutting device to the conveyor further conveying path.
  • the conveyor belt is guided on a guide.
  • the leadership of the course of the transport path and the shape of the conveyor belt can be specified in cross section.
  • the guide is shaped such that the wrap angle of the conveyor belt around the products increases perpendicular to the transport movement in the direction of the transport movement. Since the conveyor belt rests on the guide, the shape or the course of the conveyor belt can be selectively changed by an appropriate shaping of the guide, which is used in this case to increase the wrap angle by the guide eg by a deepening groove with a decreasing radius is formed.
  • the conveyor belt then rests on the guide in the channel so that the conveyor belt moves around the products at an increasing wrap angle in the direction of transport of the products.
  • the increasing angle of wrap leads to an increase in the frictional forces acting on the individual products during the transport movement, so that the products are taken along at a continuously increasing speed, until they finally reach the same Speed can be transported as the second higher speed of the conveyor belt.
  • the second speed of the conveyor belt is controllable.
  • the controllability of the second speed is advantageous insofar as this indirectly the overspeed of the transfer conveyor can be changed without the need to change the speed or the number of lever arms of the further conveyor.
  • Fig. 1 a longitudinal conveyor
  • FIG. 2 shows a sectional view in direction A-A from FIG. 1;
  • FIG. 3 shows a sectional view in the direction B-B from FIG. 2.
  • FIG. 1 shows a longitudinal conveyor according to the invention can be seen, which is used for the transport of rod-shaped products of the tobacco-processing industry, such as filter sticks or tobacco sticks.
  • the longitudinal conveyor is supplied from the right with an endless strand 4 of the product driven at a first speed VI via a format belt 13.
  • This endless strand 4 was produced in a previous step from a raw mass of tobacco fibers or filter material and a wrapping strip in a format section, wherein the wrapping strip is wrapped around the raw mass in the format section and then by means of a glue track the longitudinal edges is glued to a rigid strand.
  • This endless speed moved with the first speed VI
  • Strand 4 is cut in a cutting device 1 into products 5 having a defined length.
  • the cutting device 1 is formed by a rotating knife carrier 11 with two radially projecting knives 12, which periodically pass through the strand 4 during the rotational movement of the knife carrier.
  • the transport device 3 After the products 5 have been cut off, they are actively transported away by the transport device 3 provided according to the invention, namely at a second speed V2, which is higher than the first speed VI of the endless strand 4 in front of the cutting device 1.
  • the transport device 3 is connected by an endless conveyor belt 6 formed, which rests on a guide 7, in the form of a guide rail.
  • the guide 7 is shaped as a groove which recedes in the transport direction of the products 5 and has a decreasing radius R, as can also be seen from the sections shown in FIGS. 2 and 3 in the cutting direction A-A and B-B.
  • the guide 7 has a first radius Rl, resulting in a first wrap angle Cl of the conveyor belt 6 on the product.
  • the conveyor belt 6 rests on the guide 7 and comprises the products 5 due to the shape of the guide 7 in the transport direction with an increasing wrap angle C, so that the frictional engagement between the conveyor belt 6 and the products 5 also increases in the transport direction.
  • This enlarged wrap angle C can be seen in the sectional plane BB shown in FIG. 3, in which the guide 7 has a much smaller second radius R2, so that the conveyor belt 6 rests against the product 5 with a second wrap angle C 2, which is greater than the first wrap angle C 1.
  • the products 5 are initially transported away only after the takeover of the cutting device 1 only with a slightly higher speed and accelerated during the further transport path over a longer path only to the second speed V2, so that the maximum occurring acceleration and the forces caused thereby can be limited to the lowest possible value.
  • the transport device 3 can be designed so that the products 5 are already pulled away during the cutting in the cutting device 1 at a slightly higher speed than the first speed VI of the strand 4, whereby the cutting process favors and a clean cut surface can be achieved.
  • the products are moved from a certain point at the second higher speed V2, whereby the products 5 are now occasionally guided with small gaps due to the higher second speed V2 compared to the first speed VI, so that the products 5 can not accumulate in any case.
  • the second speed V2 can also be chosen such that the gaps are only very slight or absent and the products 5 abut each other without the mutual exertion of longitudinal forces.
  • the speeds at which the products 5 are conveyed along the conveying path are shown in FIG. 1 by the arrows and the regions delimited from one another.
  • the further conveyor 2 has a drum which is driven to a rotary movement in the direction of arrow S about a rotation axis D.
  • Aligned lever arms 9 are at the end face "of the drum parallel to the axis of rotation D provided, which are rotatably supported itself against the drum.
  • the lever arms 9 are parallel to the fed products 5 aligned troughs 10 are provided, which in the take-up point 8 During the rotational movement of the drum in the direction of arrow S, the lever arms 9 perform an opposite rotational movement, so that the troughs 10 have a constant horizontal orientation during the rotational movement the products 5 are taken over by the troughs 10 in the transfer point 8. This is particularly advantageous with products having a shorter product length 5. If the speed V2 of the transport device 3 is even controllable, the overspeed can also be controlled by the control of the VELOCITY V2 speed of the transport device 3 are controlled without that the rotational speed of the conveyor 2 must be changed.
  • the invention allows the advantage that an important parameter on which the overspeed depends, namely the product length, now has a much smaller influence on the overspeed.
