DETAILED DESCRIPTION
[0074] The particulars shown herein are by way of example and for purposes of illustrative discussion of the embodiments of the present invention only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the present invention. In this regard, no attempt is made to show structural details of the present invention in more detail than is necessary for the fundamental understanding of the present invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the present invention may be embodied in practice.
[0075] Within the context of the invention, features which are identified by in particular or preferably are to be understood to be optional features.
[0076] In the drawings, the same or similar elements and/or parts are, in each case, provided with the same reference numerals so that they are not introduced again in each case.
[0077]
[0078] The device 2 comprises a feed device 4 which is designed to guide the mass flow in a transport area 6. The feed device 4 is, for example, a conveyor belt which is guided by guide rollers which are not provided with reference numerals. The transport area 6 is, for example, a plane or is virtually planar. The feed device 4 is designed to convey the mass flow in a transport direction T. A detection device 8, for example a camera arrangement, is situated at the end of the feed device 4. The detection device 8 is designed to illustrate and analyze the mass flow guided on the feed device 4. Deviating from the representation in
[0079] Starting from the feed device 4 in the transport direction T, the mass flow finds its way along a flight parabola to a discharge device 10. In flight, the small parts of the mass flow pass through a rejection device 12 and a non-tobacco related material receiving device 14.
[0080] The discharge device 10 is designed to receive the purified mass flow, which is also to be referred to as the good product flow, from the feed device 4, and to provide it for further processing. The discharge device 10 is, in turn, for example, a conveyor belt which is guided around deflection pulleys which are not provided with reference numerals.
[0081] During the flight phase of the mass flow from the feed device 4 to the discharge device 10, said mass flow passes through the rejection device 12 which is, for example, a pneumatically operated nozzle strip. The detection device 8 is designed to detect a non-tobacco related material present in the mass flow and to generate a non-tobacco related material detection signal S and to transmit said signal to the rejection device 12.
[0082] The rejection device 12 is designed to receive the non-tobacco related material detection signal S and to reject the non-tobacco related material present in the mass flow during the free flight phase thereof from the mass flow. The non-tobacco related material is removed pneumatically from the mass flow by deflecting it with a blast of compressed air emitted by the rejection device 12 which is configured, for example, as a nozzle strip from the transport direction T in the direction of a rejection direction R. The rejection direction R is that direction in which the blast of air provided to blow out the non-tobacco related material is emitted by the rejection device 12. The resulting trajectory of the non-tobacco related material is produced by corresponding vector addition. It substantially corresponds to the rejection direction R, provided that the blast of compressed air is strong enough. As a result of the rejection process, the non-tobacco related material finds its way into the non-tobacco related material receiving device 14 which is designed and arranged to receive the deflected non-tobacco related material.
[0083] The non-tobacco related material receiving device 14 has a separating member 16 which is a plate-shaped, lamellar member, the longitudinal extension direction of which is oriented transversely to the transport direction T. The separating member 16 has an upper separating edge 18 facing the mass flow, which separates the non-tobacco related materials from the good product flow. That is to say that, if the non-tobacco related materials are not extracted from the mass flow more or less directly in the rejection direction R, for example because the air flow utilized for the rejection does not hit the non-tobacco related material centrally, but only grazes it, the non-tobacco related materials collide with the underside of the separating member 16 facing away in
[0084] In addition to the separating member 16 and the retaining device 20, the non-tobacco related material receiving device 14 comprises a collecting container 22 in which the rejected non-tobacco related materials are collected and transported away. For example, a conveyor belt which is not depicted is provided in the lower region of the collecting container 22 for transporting away the non-tobacco related materials.
[0085]
[0086]
[0087] The transport direction T and the rejection direction R (cf.
[0088] In addition to the already known components of the device 2,
[0089] The retaining device 20 is, by way of example, cuboid. The deflecting member(s) 26 is/are, by way of example, plate-shaped. The retaining device 20 and the deflecting members 26 are, for example, manufactured from metal. The fastening position 28 is, for example, linear. The deflecting member 26 with its large side edge is attached to the respective chute wall 24a, 24b along said linear fastening position 28. The angle by which the deflecting members 26 are inclined according to the exemplary embodiment depicted in
[0090] The retaining device 20 of the device 2 shown in the previously explained exemplary embodiments has in each case multiple deflecting members 26. In the exemplary embodiment depicted in
[0091]
[0092] The deflecting members 26 arranged in the retaining device 20 substantially have a first and a second effect on the non-tobacco related materials F deflected by the rejection device 12. The deflecting members 26 produce the first effect when a non-tobacco related material F collides with an upper side 32 of the deflecting member 26 in the rejection direction R. Said impact event leads to a deflection of the non-tobacco related material F in a first deflection direction which is depicted by a dashed arrow. The position of the non-tobacco related material F shortly after the impact event is likewise depicted in dashes. It is important that the non-tobacco related material F is deflected in a direction which differs significantly from the rejection direction R. This significantly reduces the probability that the non-tobacco related material F will find its way back into the good product flow G (cf.
[0093]
[0094] If a plurality of rejection processes take place with the rejection device 12, a not inconsiderable air flow, which is directed into the retaining volume V, can be produced as the sum of the individual pneumatic blasts. This can lead to an excess pressure occurring within the retaining volume V, which could merely be dissipated via the inlet opening 36 of the retaining device 20 (cf.
[0095] The air-permeable regions 38 are integrated, by way of example, in a region, into the chute walls 24 which lie below the deflecting members 26. Thus, surplus air from the retaining volume V can stream out from the retaining volume V in such a region in which the non-tobacco related materials F are safely prevented from flowing back into the good product flow G. If the non-tobacco related materials F are carried along by the air flow steaming out through the air-permeable regions 38, it is very probable that impact processes such as those described in connection with the second effect in the context of
[0096] As already mentioned previously, the retaining device 20 is, by way of example, cuboid. The large flat sides opposite one another of said cuboid are formed by the first and second chute walls 24a, 24b. The first and second chute walls 24a, 24b each extend transversely in a plane, in particular vertically to the rejection plane E (cf.
[0097] Furthermore, it is provided, for example, that the deflecting members 26 provided on the different chute walls 24a, 24b are arranged at different distances from the rejection device 12 (cf.
[0098] Furthermore, it is provided that a channel 40 is formed between the free ends 30 of the deflecting members 26 provided on opposite chute walls 24a, 24b. In the lower region of the retaining device 20, as shown in
[0099] The deflecting members 26 can be articulated so as to be pivotable at least in sections at the fastening position 28. That is to say that the angle of the deflecting member 26 can be changed at least in sections. For example, the angle of the deflecting member 26 can change, as indicated in
