Description
Technical Field
The invention relates to a pushing roller for the tobacco processing industry.
The invention also relates to a machine of the tobacco processing industry, in particular a filter production machine or a filter tipping machine, and a filter rod segment providing device for providing filter rod segments made of filter rods.
Background
Conveyor drums are used in machines of the tobacco processing industry, in particular filter tipping machines or machines for producing various smoking products, such as thermal non-combustible products or electronic cigarettes, for conveying cigarettes, filter blocks or parts thereof.
During the production of cigarettes, filters and filter cigarettes or so-called hot non-combustible products or electronic cigarettes, the transport of the aforementioned rod-shaped articles is generally carried out in modern tobacco processing industry manufacturing machines by means of transport rollers, the housing surfaces of which or the roller bodies of which are provided for the transverse axial transport of the rod-shaped articles (cigarettes, filter rods or plugs, filter cigarettes) with grooves or receiving pockets for receiving the rod-shaped articles. The receiving cavity in this case has a cavity floor. Rod-shaped articles of the tobacco processing industry are generally arranged in rows of transverse axes one behind the other in the receiving pockets during transport.
Furthermore, as conveyor rollers, for example, a pusher roller in a filter feeder on a filter tipping machine is also known, on which the filter plug is pushed in the longitudinal direction as a rod-shaped article. In this case, multiple lengths of filter rods are removed from a filter rod magazine on a filter feeder with a plurality of transfer drums and double length filter plugs are cut on a cutting drum. The filter plugs are staggered on the staggered drum after cutting, that is, each cut filter plug is individually staggered from the next filter plug in one pocket of the staggered drum. The staggered filter plugs are then displaced longitudinally in the receiving pockets on the displacement cylinder in a further method step, so that the filter plugs are then aligned in rows one behind the other in the transverse axial direction, whereby the filter plugs arranged one behind the other in rows are transferred from the displacement cylinder to the next transport cylinder.
The rollers are generally used in the mass production of filter rods and filter cigarettes, wherein multiple lengths of filter rods are prepared in a so-called transverse process, i.e. transversely to their longitudinal axis, by one or more of subdivision, interlacing and tandem arrangement, for subsequent connection with other filter or smoking article components.
In EP 1013181A2 a push/cut cylinder is disclosed, in which a smoking article component or a filter block is pneumatically pushed in a receiving pocket towards a stop by applying suction air over a suction hole of a receiving portion.
In GB 2267021a filter tipping machine is described in which filter rods are taken out of two bins separately. After removal of the first filter rod, the filter rods are cut centrally and pushed away from one another in the transverse axial direction. A second filter rod from another cartridge is then inserted centrally between the sections of the first filter rod. The filter rod assemblies are then cut, staggered and advanced on the drum, respectively. The process of cutting, interleaving and pushing the filter blocks is repeated and thus performed twice in total. The combined filter produced by the two different filter rods is then transferred to an assembly drum with cigarette rods.
Furthermore, DE 102013210634A1 discloses a pusher drum for a machine of the tobacco processing industry.
Disclosure of Invention
The object of the invention is to provide a displacement roller for a filter tip supply device, for example, in which, in particular, short rod-shaped articles can be displaced in a reliable manner in the longitudinal direction.
The object is achieved by a pusher drum for the tobacco processing industry, comprising a drum body with receiving pockets arranged one behind the other in a row in the circumferential direction of the drum body, for rod-shaped articles of the tobacco processing industry, in particular filter rods and/or filter blocks and/or segmented products, wherein the drum body is rotatable about a rotational axis, wherein the receiving pockets each have a pocket bottom, wherein the pocket bottoms of the receiving pockets are each delimited by a pocket edge preceding in the conveying direction of the pusher drum and a pocket edge following in the conveying direction of the pusher drum, wherein the pocket edges extend parallel to the rotational axis of the pusher drum,
wherein the receiving recess is laterally delimited by a stop screen having a stop surface for the rod-shaped articles at least in the conveying region of the rod-shaped articles on the pusher cylinder,
wherein rod-shaped articles, each having a cross-sectional surface, in particular circular or annular, along the cavity rim and along the cavity floor, can be displaced or displaced in the longitudinal axial direction, in particular pneumatically, in the receiving cavity during rotation of the displacing cylinder, preferably towards the stop barrier,
wherein the receiving cavities each have a cavity cross-section with a cavity cross-section surface bounded by a cavity bottom and cavity edge strips,
wherein the stop surface of the stop barrier faces the article which can be arranged or is arranged in the receiving pocket, respectively, wherein the stop surface of the stop barrier is equal to or greater than the cross-sectional surface of the rod-shaped article facing the stop barrier and/or the stop surface of the stop barrier is equal to or greater than the pocket cross-sectional surface of the receiving pocket facing the stop barrier.
And wherein an air flow channel formed with a curvature is formed in the region of the stop screen, so that the air that can be conveyed or is conveyed from the receiving recess is guided around the stop screen or can be guided around it.
The invention is based on the idea that for an article or article segment to be pushed or pushed in a receiving pocket, a lateral stop is provided on all sides by a stop barrier in the receiving pocket, wherein the stop surface for a rod-shaped article in the receiving pocket is greater than or equal to the cross-sectional surface of the stop surface of the rod-shaped article facing the stop barrier, or the stop surface for a rod-shaped article is equal to or greater than the pocket cross-sectional surface of the receiving pocket. A complete stop is thereby provided on all sides for the rod-shaped article to be pushed, wherein, for example, when the rod-shaped article is pushed longitudinally in the receiving recess, the air flow channel in the region of the stop barrier cooperates with, and the dropping of the filling material in the rod-shaped article or the article section is reduced or prevented. For example, rod-shaped articles or article segments have a reconstituted or reconstituted tobacco material as filler material.
In one embodiment, a stop screen for a rod-shaped article to be pushed is arranged on the pushing roller in a fixed position relative to the rotationally driven roller body. In an alternative embodiment, the receiving pockets each have stop barriers arranged in the receiving pockets, which stop barriers rotate together when the roller body rotates.
The lateral displacement movement of the rod-shaped articles in the receiving pockets is limited by the stop barrier, so that after the rod-shaped articles have been arranged and positioned on the stop surface of the stop barrier, they are transferred from this position to the next conveyor drum in a further step.
In one embodiment of the pusher roller, a stop barrier is arranged between the ends of the receiving recess. According to a further or additional embodiment, the stop barrier is arranged laterally on one end of the receiving recess.
By forming an air flow channel, in particular a suction air flow channel, in the region of the stop barrier, which is formed with a curvature, such that during the displacement of the rod-shaped article in the receiving recess, by applying a negative pressure on the curved air flow channel, the negative pressure acts on the end of the rod-shaped article to be displaced facing the stop barrier, wherein the rod-shaped article is moved in the direction of the stop barrier and is positioned on the lateral stop barrier as a result of the negative pressure between the end of the article and the stop barrier.
In this case, the air flow channel can branch off from the recess bottom in the region of the stop barrier in one embodiment via a recess or the like in the cylinder body and can be subjected to a negative pressure from a negative pressure source. In one embodiment, the air flow channel can also be formed above the stop screen, for example between the cover for the receiving recess and the stop screen.
By means of the stop screen having stop surfaces on all sides, an air flow channel with a curvature is provided in the region of the stop screen, so that, for example, suction air is guided around the stop screen. The air flow channel is according to a further aspect configured as an air-encircling flow channel for the stop barrier, for example by a recess in the cavity bottom of the receiving cavity or by a partial space in the cover for the receiving cavity above the receiving cavity. In one design the air flow channel is configured in the cavity floor of the receiving cavity such that the air flow channel is configured as a lower flow channel below the stop barrier. According to a further, in particular alternative or further embodiment, the air flow channel is formed above the stop barrier or also laterally in at least one recess rim or in both recess rims delimiting the recess bottom of the receiving recess.
According to a further aspect, a cover, in particular fixed in position, for receiving the recess is arranged on the push roller in the conveying region of the rod-shaped article, wherein in particular the cover extends in the circumferential direction of the push roller and is curved in the circumferential direction of the push roller. The cover is arranged in particular on the pushing roller in a conveying area in which the longitudinal axial pushing of the rod-shaped articles in the receiving pockets is carried out. The receiving recess is preferably configured in a basin-like manner, wherein in particular the recess rim has a (radial) height such that the recess rim protrudes beyond the rod-shaped article arranged in the receiving recess.
By arranging the cover such that no negative pressure is applied to the rod-shaped article, such as during transport of the segments, within the transport region of the cover, the rod-shaped article is moved in the longitudinal axial direction towards the stop barrier by switching off the retaining air or the retaining negative pressure in the receiving recess in the transport region of the cover and by applying the suction air acting in the longitudinal axial direction for pushing the rod-shaped article in the receiving recess. The rod-shaped article is thereby moved or sucked towards the stop by means of the pushing suction air acting in longitudinal direction.
In a further development of the pusher cylinder, the cylinder body has a circumferential groove with a groove bottom for receiving the stop barrier, wherein the radial distance of the groove bottom of the circumferential groove from the axis of rotation of the pusher cylinder is smaller than the radial distance of the recess bottom of the receiving recess from the axis of rotation of the pusher cylinder. The radial distance of the groove bottom of the encircling groove from the axis of rotation of the pushing cylinder is smaller than the radial distance of the groove bottom from the axis of rotation of the pushing cylinder, so that a stop barrier is arranged in the groove, wherein the stop barrier is arranged with a lower edge in the groove in this case, wherein the lower edge of the stop barrier is positioned deeper than the recess bottom of the receiving recess. In this case, in order to form the air flow channel, a depression or the like is formed in the receiving recess or in the roller body below the lower edge of the stop screen in the region of the stop screen, in order to form the air flow channel below the lower side of the stop screen.
Furthermore, according to a refinement, it is provided that the stop screen is arranged in the conveying region of the rod-shaped articles, preferably in a stationary manner in relation to the rotating or rotatable drum body, in the circumferential groove of the drum body, wherein in particular the stop screen having a lower edge is arranged in the circumferential groove in such a way that the lower edge of the stop screen is closer to the axis of rotation of the pusher drum than the pocket floor of the receiving pocket. At least a part of the air flow channel is formed in the roller body below the underside of the stop screen.
In a further development of the roller body, it is provided that in the region of the stop barriers, in each case one air flow channel is formed in the recess base of the respective receiving recess.
Furthermore, a design of the pushing cylinder is characterized in that the cover is arranged on the pushing cylinder by means of a cover holder and/or a stop screen by means of a stop screen holder, or the cover and the stop screen are arranged on the pushing cylinder by means of a common holder, or the stop screen is arranged on the cover, or the cover is arranged on the stop screen.
According to a further aspect and embodiment, it is advantageous in the pusher roller for each receiving recess to have a stop barrier for the rod-shaped articles.
In addition, in one embodiment of the pusher roller, it is advantageous if the air flow channel is arranged between the respective recess receiving stop barrier and the recess bottom and/or the respective recess edge of the receiving recess and/or the rear recess edge. Furthermore, according to a development, the air flow channel is formed between the respective stop barrier of the receiving recess and the cover.
In order to form the air flow channel above the stop screen arranged in the receiving recess or on the receiving recess, in a development of the pusher drum, provision is made for the cover to have a radially outwardly formed profile or a radially outwardly formed bulge in the region of the stop screen of the receiving recess.
The object is furthermore achieved by a machine of the tobacco processing industry, in particular a filter production machine or a filter tipping machine, which is configured with the above-described pusher roller.
The object is furthermore achieved by a filter rod segment provision device for providing filter rod segments made of filter rods, wherein the filter rods and/or the filter rod segments are transported or transportable transversely on the filter rod segment provision device, which is configured with the previously described pusher drum according to the invention. To avoid repetition, reference is explicitly made to the preceding description.
Other features of the invention will be apparent from the description of the embodiments according to the invention, taken in conjunction with the claims and the accompanying drawings. Embodiments according to the invention may fulfil single features or a combination of features.

Detailed Description
Fig. 1 shows a perspective view of a pusher cylinder according to the invention. Fig. 2 shows a schematic, not-to-scale cross-sectional view of the pusher cylinder 10. The pusher roller 10 has an outer roller body 12 with a receiving recess 14, which is driven in rotation about an axis of rotation R. The cylinder body 12 encloses a control body 11 arranged inside the pusher cylinder 10 for controlling the suction air provided on the respective bore hole of the cylinder body 12, by means of which the rod-shaped article a is held in the receiving recess 14 or is moved longitudinally.
The drum body 12 has receiving pockets 14 in the circumferential direction, into which rod-shaped articles a are received from the conveying drums arranged upstream and in which receiving pockets 14 the rod-shaped articles a are displaced in the longitudinal axial direction, i.e. parallel to the axis of rotation R of the displacing drum 10.
The pusher roller 10 is in this case a component of a roller system, for example a filter providing device or a filter tipping machine or the like. The received rod-shaped articles a, such as filter rod segments or filter rods, are transported in a transverse axial direction by means of the displacement roller 10, wherein during the transverse axial transport of the rod-shaped articles a on the displacement roller 10, the rod-shaped articles a are displaced in the longitudinal axial direction in the receiving pockets 14 in the transport region in the longitudinal axial direction.
The pushing roller 10 has a cover 16 on its outer side in a conveying area, in which the rod-shaped articles a are pushed in the longitudinal direction in the receiving recess 14. The cover 16 partially or completely covers the conveying area in which the rod-shaped articles a are displaced longitudinally in the receiving recess 14. For example, the cover 16 is made of plastic, such as Polyethylene (PE) or another bendable or formable material.
The cover 16 is arranged on the outer side of the push roller 10 in a conveying region in which the rod-shaped articles a received in the receiving pockets 14 are pushed in the longitudinal direction, wherein the cover 16 is arranged on the outer side of the push roller 10 via the holders 160.
As can be seen from the cross-sectional illustration of fig. 2, the receiving pocket 14 has a suction air borehole 18, to which a negative pressure is applied in a conveying region in which the rod-shaped articles a arranged in the receiving pocket 14 are displaced longitudinally. In this case a suction air bore 18 is formed on one end of the receiving cavity 14.
Fig. 3 shows a schematic top view of a receiving recess 14 of the pusher cylinder 10 in section. The receiving pocket 14 has a pocket bottom 141, which is delimited with respect to the conveying direction of the conveying cylinder by a preceding pocket edge strip 143 and a following pocket edge strip 142. The suction air bores 18 are in this case formed in the recess bottom 141 of the respective receiving recess 14.
The pocket bars 142, 143 furthermore have circumferential grooves 20 (see fig. 2) in the circumferential direction of the pusher drum 10 or drum body 12, wherein the stop plate 22 is arranged as a stop barrier for the rod-shaped articles a in the conveying region in which the rod-shaped articles a are pushed longitudinally in the receiving pockets 14. The rod-shaped article a to be pushed is received in the receiving recess 14 on the side of the stop plate 22 facing away from the other side of the stop plate 22 facing the suction air borehole 18. In other words: a stop plate 22 configured as a stop barrier is arranged between the suction air bore 18 and the rod-shaped article a (to be pushed).
The circumferential groove 20 has a groove bottom in this case, the radial distance of which from the axis of rotation R of the pusher cylinder 10 is smaller than the radial distance of the recess bottom 141 of the receiving recess 14 from the axis of rotation.
The stop plate 22 is arranged on the displacement cylinder 10 in the trough 20 in the conveying region of the rod-shaped articles a, in which the rod-shaped articles a are displaced longitudinally in the receiving recess 14, such that the radial distance of the lower side of the stop plate 22 from the rotation axis R is smaller than the radial distance of the recess bottom 141 of the receiving recess 14 from the rotation axis R. Furthermore, in the region of the stop plate 22 and in the region of the recess bottom 141 of the receiving recess 14, a lower flow channel 24 is formed below the stop plate 22, so that in the conveying region (in which the rod-shaped article a is displaced longitudinally) air is sucked through the lower flow channel 24 by applying the suction air borehole 18, wherein the stop plate 22 in this case acts as a stop barrier for the rod-shaped article a, so that the rod-shaped article a moves with one end face in the direction of the stop plate 22.
The stop plate 22 provides a lateral stop for the rod-shaped article a on all sides of the rod-shaped article a, wherein the stop surface facing the rod-shaped article a is greater than the cross-sectional surface of the rod-shaped article a or the cross-sectional surface of the recess of the receiving recess 14 between the recess edges 142, 143 and the recess bottom 141.
The stop plate 22 is partially annular in the circumferential direction of the pushing cylinder 10 and is arranged on the pushing cylinder 10 together with the cover 16 on the holder 160 in a retaining manner. In a design (not shown), the stop 22 is configured in the form of a ring.
In order to hold the rod-shaped articles a arranged on the stop plate 22 after the longitudinal axial displacement thereof in the receiving recess 14, a holding-air bore 26 is provided in the drum body 12, so that the rod-shaped articles a are held on the holding-air bore 26 by applying a negative pressure via the holding-air bore 26 formed in the drum body 12 and are transported under the rotation of the displacement drum 10 to the next transport drum toward the transfer point. The holding air bore 26 is in this case constructed in the cavity bottom 141 of the receiving cavity 14.
A further lateral stop 122 is arranged at the end of the receiving recess 14 opposite the suction air bore 18, wherein the lower edge of the stop 122 has a smaller radial distance from the axis of rotation R than the recess bottom 141 of the receiving recess 14. In addition, an air flow channel 124 is formed in the region of the stop 122 of the receiving recess 14, so that air can flow between the roller body 12 and the stop 122 via the air flow channel 124. The air flow passage 124 is laterally connected to the vent bore 28. The air flow channel 124 is furthermore connected to the suction air bore 30.
In the event of a movement of the rod-shaped article a in the receiving recess 14 in the direction of the stop plate 22, the respective suction air bore 18 of the receiving recess 14 is opened by means of the control body 11 arranged inside the roller body 12, so that during the closing of the suction air bore 30 and the opening of the ventilation bore 28, a negative pressure is applied to the suction air bore 18 during a longitudinal axial displacement movement of the rod-shaped article a in the receiving recess 14, so that air flows (successively) into the receiving recess 14 via the ventilation bore 28 and the air flow channel 124.
The article a is received in the receiving cavity 14 with the corresponding vent drilling 28 closed. The suction air from the bore 30 positions the respective article a on the stop 122 in that the cover 16 is open or is opened above the suction air bore 18, whereby air can flow successively there
Or are flowed sequentially. The suction air is opened by a time-staggered control time for the suction air drilling 30 in the control body 11. Next, the control body 11 opens the suction air supply for the suction air bore 18 and closes the cover 16 above it and opens the ventilation bore 28, so that the article a is positioned on the stop 22.
In order to facilitate the longitudinal axial displacement of the rod-shaped article a in the receiving recess 14, a corresponding ventilation opening or the like is provided in the cover 16 in a further embodiment.
All of the features mentioned, including those which will be taken individually from the figures, as well as the individual features disclosed in connection with the other features, are considered essential for the invention, both individually and in combination. Embodiments according to the invention may be implemented by means of a single feature or a combination of features.
