Benefits of technology

[0010] According to the invention, a distributor device of the present invention includes the above-noted features of the distributor device discussed above, and further includes that the distributor device comprises, in addition to the input device, at least one further external delivery device for the delivery of at least one further component into the distributor device or into the product stream. The delivery device is arranged between the store and the sifter in the direction of transport of the product stream. As a result, in a surprisingly simple and particularly effective manner there is provided the possibility of adding at least one additive or component to the product stream within the distributor device and mixing it with the product stream. Due to the additional external delivery device, therefore, e.g., different tobacco varieties can also be mixed directly within the distributor device. Also further additives, e.g., cloves, dust aggregates, etc. can be mixed with the product stream within the distributor device. In other words, the external delivery device does not mean a recirculation device within the distributor device, e.g. the recirculation of excess tobacco to the store for receiving the product stream, but instead a supply of any components from the outside to the product stream. Due to the fact that the delivery device is arranged between the store and the sifter, the product stream can be made particularly individual and economically advantageous, because introduction of the or each additional component can take place at different positions preventing e.g. segregation or double sifting.
[0011] In a preferred embodiment of the invention, the sifter has at least two approaches. As a result, even more individual mixing of product stream and additional components is possible. Thus, for example, there arises the possibility of delivering components to the sifter in such a way that they are not sifted very much, leading to a relief of the load on the sifter. This can also be, e.g., already sifted tobacco, such as, e.g., expanded tobacco. However, components which are not to be sifted out at all can be added, too. This applies to, e.g., the above-mentioned cloves. Conversely, of course, delivery of components at a different location of the sifter is also possible for those components which are to be sifted particularly well. Due to the plurality of approaches, segregation can also be avoided in an effective manner by conducting the heavier components via a separate approach into the sifter.
[0012] Advantageously, the cross-section d.sub.1 of the sifter in the region of the upper approach is smaller than the cross-section d.sub.2 of the sifter in the region of the lower approach. Due to this construction according to the invention, there is an increase in the flow rate of the air in the region of the upper approach, so that components conducted through the upper approach into the sifter are sifted only slightly or not at all, but carried out of the sifter immediately, this being while mixing with the follow-on tobacco stream. This is particularly advantageous for the recirculation of already sifted tobacco, as the latter then does not place an unnecessary load on the sifter. Also, as a result of the introduction of components heavier than the tobacco through the upper approach, in spite of the high tare weight, these components are not sifted out due to the high flow rate on account of the reduced diameter or cross-section, but instead mix with the product stream introduced through the lower approach into the sifter.

Problems solved by technology

All known distributor devices and methods which are used for loading a continuous cigarette-making machine do however have the drawback that the tobacco varieties and possible additives or components must be mixed before the distributor device, which prevents individual and flexible merging of the product stream.
Also, it is disadvantageous that the complete product stream formed from different components, namely tobacco components and additives, at least partially segregates during transport by the distributor device.
As a result, a non-homogeneous product stream is produced, and the product stream no longer has the desired mixture.
Furthermore, it has happened that tobacco residues which are produced during actual tobacco string manufacture and which have already been sifted, e.g. so-called excess tobacco, are sifted again within the distributor device upon recirculation, which is not economical and increases the load on distributor devices.

Embodiment Construction

[0044] 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.

[0045] The distributor devices described in FIGS. 1 to 4, also referred to as distributors below, serve to measure out and sift the product stream usually delivered to them via an air stream, and, while mixing with at least one further component, from the sifted material to form one or more tobacco streams which are then...

Abstract

Distributor device and method of distributing that includes an input device for the input of a product stream, a preliminary distributor for distributing, measuring out and loosening the product stream, a store for receiving the product stream, an accumulating shaft, and a sifter for separating fractions of the product stream. The distributor device also includes a conveying element for transporting the product stream from the store to the accumulating shaft, and at least one external delivery device for delivery of at least one additional component. The at least one external delivery device is arranged between the store and the sifter relative to a transport direction of the product stream. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Description

[0001] The present application claims priority under 35 U.S.C. .sctn. 119 of European Patent Application No. 03 09 0021.1 filed Jan. 28, 2003, the disclosure of which is expressly incorporated by reference herein in its entirety.[0002] 1. Field of the Invention[0003] The invention concerns a distributor device, in particular for loading a continuous cigarette-making machine. The distributor device essentially includes an input device for the input of a product stream, a preliminary distributor for distributing, measuring out and loosening the product stream, a store for receiving the product stream, and a conveying element for transporting the product stream from the store to an accumulating shaft. Optionally, in front of or behind the accumulating shaft in the direction of transport of the product stream a sifter is arranged for the separation of fractions of the product stream which are to be processed and not to be processed.[0004] Further, the invention concerns a method, in par...
