Summary of the invention
Therefore, the objective of the invention is to, propose improved device and improved method to be used to the making bundle bar that at least one tobacco is handled industry, it realizes the improvement demand that one or more is mentioned.
This purpose realizes by the device of the mentioned type of beginning, it is characterized in that, bundle bar guiding channel has second section that is used to tremble out first section of bundle bar (zum Aufschauern des Stranges) and is used for extracting (absaugen) surplus air, at this, first and second sections are limited by at least one suction band at the suction edge side at least.
Prior art is owing to the present invention especially further improves in view of the structure of device, because the present invention has reduced the tobacco loss, reduced the obstruction in the flow of tobacco (as the especially obstruction of slype), reduced cleaning cost and first-selected also provide simple and to be achieved efficiently structure.
Similarly be applicable to the only bundle bar of a tobacco processing industry of manufacturing according to device of the present invention, be particularly useful for making and be used to make the tobacco bunch bar of cigarette or be applicable to that also making one or more is used to make filter-tip bundle bar, as in order to make the bundle bar two or more.Under the situation of making two or more such bundle bars, the corresponding element (as bundle bar guiding channel and suction band) of this device is set with the quantity of corresponding increase equally.Suppose that in description embodiment relates to the manufacturing of only single bundle bar, can migrate to the equally device of the manufacturing that is used for two or more bundle bars of these embodiments.
Two different sections (perhaps also being called sections) of bundle bar guiding channel outstanding therefrom according to structure of the present invention (be used to tremble out the bundle bar on the one hand and be used to extract surplus air on the other hand) promptly, makes two sections extend at least one and aspirates band place.
Arrangement according to the invention becomes possibility below making, has promptly realized the extraction of surplus air and trembling out of bundle bar near at least one aspirates be with direct.On the contrary, the solution setting that exists in the prior art is extracted surplus air on the direction that suction band guiding is certainly left with in the big spacing of suction band.At this, the knowledge of institute of the present invention foundation is to extract surplus air (that is, extracting in second section that is limited by at least one suction band) as far as possible lately, cause reducing of tobacco loss on the one hand, cause improved more uniform bundle bar structure (Strangaufbau) on the other hand.
Additional advantage according to device of the present invention is, especially in second section, can obviously reduce obstruction or obstruction in the possible air stream, because by according to the layout of two sections of the present invention with especially by at first directly carrying out the extraction of residual gas near at least one suction band thereby in second section, having the less material of waiting to tremble out (aufzuschauerndesMaterial) (especially tobacco and if necessary the time additive), material may be deposited in second section and therefore may cause the infringement of air stream, especially stops up.When in second section, having the less material of waiting to tremble out, also can obviously reduce in an advantageous manner owing in second section, by mistake extracting the loss that the material waiting to tremble out causes, especially lose for tobacco.
In addition, utilize according to the mentioned advantage of the layout of the part of device of the present invention can be especially simply and the structure that cleans easily and safeguard realize.
Preferably, two sections of bundle bar guiding channel finish with the height of at least one suction band.In addition, preferably first and second sections not only stretch along bundle bar guiding channel on the direction left of guiding but also stretch along at least one suction band on direction parallel with at least one suction band or throughput direction taking up from least one suction, preferably on the whole length of build-up areas (Aufsch ü ttbereich).
The present invention can improve thus, that is, make first and second sections observation on the throughput direction of suction bundle bar conveyer of bundle bar guiding channel be arranged on side direction contiguous.The preferred layout of two sections is parallel to the throughput direction distribution of aspirating bundle bar conveyer corresponding to bundle bar guiding channel basically and is divided at least the first and second sections.Utilize arrangement according to the invention especially preferred mode to realize that two sections stretch along bundle bar guiding channel on throughput direction.
