A production system 1 for manufacturing rod-shaped articles shown in FIG. 1 includes a production machine 2 for manufacturing rods, and a processing machine 3 for processing the rods manufactured by the production machine 2. Specifically, the rod manufactured by the production machine 2 is a multi-element rod-like article 6 with a length for two pieces, and the rod manufactured by the processing machine 3 is a multi-element rod-shaped article with a length for one piece. This is a rod-shaped article 9. During processing of the two-piece multi-element rod-like articles 6 on the processing machine 3, they are converted into single-piece multi-element rod-like articles 9, which can be further processed. For example, additional elements may be attached to the single rod-shaped article 9.

The production machine 2 is provided with supply units 2A, 2B, and 2C for supplying three types of rod-shaped elements A, B, and C, respectively. Rod-like elements A, B, C are arranged on a conveyor belt. The production machine 2 is equipped with a known forming unit for forming the multi-element continuous rod CR. As shown in FIG. 1, the continuous rod CR is moved in a direction along the axis of the continuous rod using a transport unit 4 that can be integrated with the forming unit.

It is represented by the second direction T2. Inside the processing machine 3, the two-piece multi-element rod-shaped article 6 and the one-piece multi-element rod-shaped article 9 formed during the process are conveyed in the direction T2, and they are conveyed into the groove of a continuous drum conveyor. be done. It is possible to have a machine arrangement in which there is an obtuse angle between the second direction T2 and the first direction T1. FIG. 2 shows a production machine 2' for manufacturing tobacco rods connected to a processing machine 3' by a conveying device 8', but between the second direction T2 and the first direction T1. The 180° angle is maintained and the dual tobacco rods are further rotated during transport.

The course of the process carried out in the processing machine 3 is illustrated in a simplified manner in FIG. 3 in the form of a rod-shaped article in successive stages of the process. In the exemplary machine 3 fragment shown in FIG. 4, the first drum conveyor 11 receives two rod-shaped articles 6 from the conveying device 8 and conveys them at a second conveying speed v2. On this conveyor and on subsequent conveyors, double and single rod articles are held in the groove by the vacuum provided by the holes in the bottom of the groove. Two multi-element rod-shaped articles 6 are conveyed onto a drum conveyor 12 . On the drum conveyors 11 and 12, the rod-shaped articles 6 for two pieces are conveyed in the form of two input streams S1 and S2 (FIG. 3), moving at a second conveying speed v2, while the two rod-shaped articles 6 The rod-shaped articles 6 remain in their first configuration, ie they are arranged coaxially with respect to each other. The conveyor 12 may be provided with a long groove and may include two coaxial drum conveyors. After being conveyed by the drum conveyor 15, the first stream S1 and the second stream S2 of the two rod-shaped articles 6 are transferred to a support 18 rotatable with respect to the drum conveyor 16 and to the drum conveyor 16. It is conveyed onto a drum conveyor 16 provided with a non-rotatable support 19. The supports 18 and 19 are provided with grooves for conveying two rod-shaped articles 6. One stream S1 of the rod-shaped articles 6 for two pieces is conveyed into the groove of the rotatable support 18, and the second stream S2 of the rod-shaped articles 6 for two pieces is conveyed into the groove of the non-rotatable support 19. conveyed into the groove. During rotation of the drum conveyor 16, the configuration of the two rod-shaped articles is changed. That is, the two rod-shaped articles 6 of the second stream S2 are rotated 180 degrees and placed between the two rod-shaped articles 6 of the first stream S1. As a result of the rotation of the rod-shaped article 6 for two pieces, the first input flow S1 and the second input flow S2 are connected to each other, and an intermediate flow S of the rod-shaped article 6 for two pieces is formed and separated. is conveyed onto the drum conveyor 17. In the second configuration, the rod-shaped article for two pieces is arranged such that the geometric center M of the rod-shaped article for two pieces is located within a plane k parallel to the second direction T2, and moves within this plane. It will be moved as follows. In such a configuration, the double rod-shaped articles 6 also move on the drum conveyor 17 and subsequent drum conveyors. While the intermediate flow S of the rod-shaped articles 6 for two pieces is being conveyed on the drum conveyor 17 at the second conveyance speed v2, quality control of such articles is performed. The radiation source 20 is arranged inside the drum conveyor and the radiation passes through the individual dual rod articles 6 and enters the receiver 21 . The receiver may be, for example, a camera that records the image formed by the radiation passing through the individual double rod-shaped articles 6. The grooves provided in the drum conveyor 17 are wide enough to maximize radiological inspection of such articles. Quality control can relate to the dimensions of the rod-like article or components of the rod-like article and the contents of such an article. The rod-shaped articles 6 for two pieces are conveyed from the drum conveyor 17 onto the drum conveyor 22. The drum conveyor 22 cooperates with the drum conveyor 23 and can be used to transport double rod-shaped articles 6 selected as samples for separate quality control or random quality control, while The article 6 to be inspected is dropped into the container 10. If a defect is detected in the two-piece rod-shaped article 6, the defective article 6 can be conveyed onto the drum conveyor 23 and then removed from production. The two rod-shaped articles 6 are conveyed on the drum conveyor 22 at a speed v2, and are spaced apart on the outer periphery of the drum conveyor 22 at a pitch t2. The rod-shaped articles 6 for two pieces are conveyed from a drum conveyor 22, which is a supply drum conveyor, onto a drum conveyor 24, which is a receiving drum conveyor. On the drum conveyor 24, the rod-shaped articles 6 for two pieces are conveyed at a pitch t3 that is larger than the pitch t2 of the drum conveyor 22, and the conveyance speed v3 on the (receiving) drum conveyor 24 is the same as that of the (supply) drum conveyor 22. It is larger than the above conveyance speed v2. The ratio of pitch t3 to t2 may be 2:1, in which case the ratio of velocity v3 to v2 will also be 2:1. The ratio of pitch t3 to t2 may be within the range of 1.5 to 2.5, as is the ratio of velocity v3 to v2. Due to the above-mentioned transport speed relationship, the transport speed can be adjusted to the speed required for the second cutting after the rotation step. The two rod-shaped articles 6 are conveyed onto the drum conveyor 25 at a third conveyance speed v3. On the conveyor 25, the rod-shaped article 6 for two pieces is placed in the center, and a third cutting is performed, that is, one rod-shaped article 6 for two pieces is cut using the rotary knife 26 attached to the second cutting unit 42. Cutting into rod-shaped articles 9 for use is carried out, the cutting being carried out by cutting C-shaped elements. The third cut is carried out at conveying speed v3, and when cutting easily melting materials, the rotating knife 26 is cooled by a cooling system 27 by a flow of cold air directed towards the cutting edge of the rotating knife 26. Can be done. As with the rotating knife 13, cooling of the rotating knife 26 may occur behind the sheath guiding the article to be cut, generally opposite the cutting point. As a result of the cutting, two product streams S4 and S5 of single rod-shaped articles 9 are formed. Product streams S4 and S5 move faster than input streams S1 and S2. On the conveyor 28, the elementary rod-shaped parts 9 moving in the product streams S4 and S5 are spaced apart axially, for example according to the solution disclosed in US Pat. No. 7,296,579B1, and then , a fourth stream S4 and a fifth stream S5, of which parts are separated, are conveyed onto the drum conveyor 29. Using the drum conveyors 30, 31, the D-shaped rod-shaped articles are conveyed onto the drum conveyor 29, but the D-shaped rod-shaped articles are divided into very short pieces, e.g. a length close to the diameter of the manufactured part. They may be made of materials that are difficult to cut into pieces. The group 36 comprising two single-piece rod-shaped articles 9 and rod-shaped elements D is conveyed onto a drum conveyor 32 where they are pressed together and centered. On the subsequent drum conveyors 33 and 34, a rectangular packaging material is further wound so as to connect all the rod-shaped parts constituting the group.

FIG. 5 shows a simplified process executed by the processing machine in the second embodiment. Similar to the first embodiment, two input streams S1, S2 are formed and combined to form an intermediate stream S, and after cutting the rod-shaped articles for two, two product streams S4, S5 is formed. Similarly, the first drum conveyor 11 receives two rod-shaped articles 6 from the transport device 8 and transports them at a second transport speed v2. Two rod-shaped articles 6 are conveyed onto a drum conveyor 12. On the drum conveyor 12, the double rod-shaped articles 6 are conveyed in the form of two input streams S1 and S2 (FIG. 5) and remain in the first configuration, i.e. they are arranged coaxially with each other. has been done. The two rod-shaped articles 6 are conveyed onto drum conveyors 43 and 44, where one of the rod-shaped articles 6 is displaced relative to the other in a direction transverse to the axis of the articles. Subsequently, after conveying the rod-shaped articles for two pieces onto the drum conveyor 45, the rod-shaped articles for two pieces 6 of the second input stream S2 are placed between the rod-shaped articles 6 of the first input stream. is moved in the axial direction. Therefore, an intermediate flow S is formed from the two input flows S1 and S2. In the intermediate flow, the double rod-shaped articles 6 are in the second configuration, ie the geometrical center M is arranged in a plane k parallel to the second direction T2.

It is possible to implement the invention in which three or more two-piece rod-shaped articles are conveyed from the manufacturing machine 2. In the process shown in FIG. 7, three two-piece rod-shaped articles 6' are conveyed simultaneously. FIG. 8 shows a part of the processing machine 3 that executes this process. The two-piece rod-shaped article 6' comprises one half of a rod-shaped element G, two rod-shaped elements J and a rod-shaped element H. The three two-piece rod-shaped articles 6' are conveyed onto a drum conveyor 11, where they are kept in a first configuration, ie coaxially arranged. The continuously fed double rod-shaped articles 6' are arranged in three streams S1, S2, S3. The rod-shaped articles 6' are transported on a drum conveyor 52 such that they are conveyed in a direction transverse to the axis of the rod-shaped articles 6' and then conveyed along the axis of the rod-shaped articles 6' onto the drum conveyor 52. 50 and further onto a drum conveyor 51. On the drum conveyor 52, the rod-shaped articles 6' are further arranged in a second configuration in which the geometric centers of the two rod-shaped articles 6 are arranged in a plane k parallel to the second direction T2. It is conveyed in two intermediate streams S. Furthermore, the process is performed similarly to the previous embodiment. That is, the rod-shaped article 6' is cut, two product streams S4 and S5 are formed, and after separating the single rod-shaped article 9', another rod-shaped element is inserted between the separated articles. D is placed. In the case of short rod-shaped articles, it is also possible to transport four double-rod articles.
