Abstract

The invention relates to a device for separating rod-shaped tobacco articles for the purpose of recovering tobacco, the articles being fed to a separating means in a longitudinally aligned manner by means of a turntable. DOLLAR A The aim is to optimize the feeding and orientation of the articles. DOLLAR A This is achieved by a guide channel (6) which transfers the articles onto the turntable (9) and is curved in the direction of rotation (arrow 11) of the turntable.

Description

The invention relates to a device for separating from a filling and a wrapping of existing rod-shaped articles of the tobacco processing industry strie, with the articles on a circumferential wall in the axial direction rotating turntable and a separating agent.

Devices of the type described in the introduction serve to tobacco from defective or smoking articles separated out for testing purposes in the form of cigarettes or Recover filter cigarettes from the manufacture of cigarettes wherein the wrapping of these cigarettes is slit in the longitudinal direction, which is why Cigarettes are successively axially aligned by centrifugal force. The tobacco and wrapping or filter components are separated by Sifting and screening separated.

The invention is based, the performance and functi to increase the safety of such devices.

According to the invention, this object is achieved by a on the receiving shell of the turntable aligned, curved in the direction of rotation of the turntable guide channel.

In an optimal way to the effect of on the peripheral wall of the turntable article feed adapted to the articles centrifugal force is according to a advantageous embodiment achieved in that the guide channel with a rotating direction of the turntable curved channel section with a distance in front of The peripheral wall of the turntable opens out.

A safe, controlled transfer of the items is preferred  Further training is supported by the fact that the guiding channel is inclined downwards, covered slide is formed.

An early alignment and acceleration of the articles Measure is also by blowing air in the direction of fall of the guide channel introductory blow air connection guaranteed.

The effectiveness of such a blown air connection is optimized in that it is provided on the slide floor in the entrance area of the guide channel.

The advantage achieved with the invention is that by acting early the guided and supported flow of the successive articles, a longitudinal axial alignment is continuously forced on them, whereby a chaotic accumulation and congestion avoided and thus the throughput the article passing the lead or aligning section is increased.

The invention is described below with reference to an off in the drawing management example explained in more detail.

Here show:

Fig. 1 is a schematic side view of a separation device for save Ziga,

Fig. 2 is a plan view of a turntable with an associated guide channel according to the invention in the direction of arrow X according to Fig. 1 and

Fig. 3 is a side view of the arrangement of FIG. 2.

The only schematically shown in Fig. 1 machine of the registered type is used for processing so-called cigarette shot in the form of cigarettes separated from the manufacturing process by cutting tobacco is separated from the existing filter and paper material.

The machine is provided with a loading shaft 1 , which is delimited on the underside by a conveyor belt 2 , which ends at its discharge end in a viewing shaft 3 , the upper end of which is connected to a pneumatic conveying line 4 .

At the same time, the conveyor belt 2 opens out above the entrance of an obliquely downwardly leading guide channel 6 , which is designed as a covered, laterally closed slide or as a box provided with a lid and in the entrance area of which a blown air line 7 also opens out, which also has a blower 8 Blown air is supplied.

The guide channel 6 opens within a serving as a host shell turntable 9, wherein the guide channel 6 as shown in Fig. 2, 3 of the turntable 9 curved channel portion 12 ends with a direction of rotation (arrow 11) via the plate bottom with egg nem distance in front of the circumferential wall 9.

An encircling the outer edge of the turntable 6 rotating conveyor belt 13 is known, not shown, for. B. in US-PS 3,255,762 disclosed manner driven via a vertical drive shaft, wherein the turntable 6 forms a steering wheel order and another pulley 14 is loosely rotatable on a vertical axis. The conveyor belt 13 is - as also disclosed in US-PS - rotated by 180 ° between the turntable 6 and the deflection roller 14 , so that it runs approximately horizontally at the separation point designated by A in FIG. 1.

Above the part of the conveyor belt 13 which runs horizontally in the area of the separation point A and is supported on the underside from below, two cutting discs 16 , 17 meshing on their toothed tear-open edges are provided.

Below an outlet channel 18 of the turntable 9 extends a vibrating screen 19 , in which a counterclockwise driven Schlägerwal zen 21 equipped stationary release device 22 is integrated.

Below a delivery end of the vibrating screen 19 , a collecting container 23 is arranged.

A conveying conveyor belt 24 extends below the screen section of the vibrating screen 19 .

The device works as follows:
Through the loading shaft 1 the arrow marked Ziga saves on the conveyor belt 2 , which shafts the cigarettes through the view 3 into the guide channel 6 . Loose tobacco, paper pulp, single lagblättchen Be and the like are previously pneumatically secreted by the viewing slot 3 and transported on the back of the vibrating sieve 19th

As a result of the air flowing through the blower 8 at high speed into the guide channel 6 , the supplied cigarettes are accelerated in such a way that they are aligned by the flow of the air on the curved wall of the channel section 12 . When leaving the guide channel 6 , the aligned cigarettes are conveyed at high speed directly to the outer edge of the turntable 9 , where they are fed by the rotating conveyor belt 13 to the cutting disks 16 , 17 as an endless strand and are separated by them.

The separated cigarettes pass through the outlet channel 18 onto the vibrating screen 19 , through which the bulk of the loose tobacco immediately falls onto the collecting belt 24 . For indulgence, the paper and filter material is passed under the racket rollers 21 of the release device 22 , sieved on the rear part of the vibrating sieve 19 and then transported into the collecting container 23 .

The recovered tobacco transported on the collecting belt 24 is subjected to a visual inspection on a horizontally running belt section 25 .
