Description

Cutting Device and Cutting Method for Segments for Aerosol Generating Articles

[0001] The present invention relates to a cutting device and a cutting method for segments used in aerosol generating articles.

[0002] In an aerosol generating article manufacturing apparatus, in order to mass-produce articles, segments such as tobacco rods can be cut thousands of times per minute. The knives used in such cutting are significantly worn or chipped. Therefore, in order to ensure the quality of the articles, it is necessary to regularly polish the blades or replace the knives, which has led to an increase in the production cost of the articles. In addition, the knife replacement work involves the risk of injury to the operator. Therefore, in order to eliminate such problems, a method of cutting a tobacco rod with a laser beam has been disclosed (see Patent Document 1).

[0003] In this cutting method, since there is no need to polish the blades or replace the knives, the production cost of the articles can be significantly reduced, and the operator will not be injured during maintenance work. In addition, in this cutting method, by adjusting the output of the laser beam and the cutting time by the laser beam, that is, the contact time of the laser beam with the tobacco rod, combustion and charring of the cut surface of the tobacco rod can be suppressed, and a good cut surface of the tobacco rod can be formed.

[0004] U.S. Patent No. 4,009,723

[0005] In Patent Document 1, even if the laser beam output and cutting time are adjusted, the filler material used to fill segments such as tobacco rods may undergo physical or chemical changes due to the high temperature of the laser beam, potentially degrading the quality of the product. Therefore, in Patent Document 1, an inert gas or cooling gas is injected along with the laser beam when cutting the segments. However, concerns remain that organic matter in the segment filler material may oxidize at high temperatures, leading to a degradation of the product's quality. Oxidation of the filler material poses a risk to the taste of the product. Furthermore, the gas used becomes a new consumable item replacing the knife, and the pressure vessel used to fill the gas at a predetermined pressure must be strictly controlled in accordance with the law. Consequently, it is not possible to effectively reduce the production cost of the product.

[0006] This invention has been made in view of the above problems, and aims to provide a cutting apparatus and cutting method for segments of aerosol products that can reduce the production cost of aerosol products while ensuring the quality of the aerosol products.

[0007] To achieve the above objective, a segment cutting apparatus for aerosol products according to one embodiment comprises a transport path through which the segment is transported along its axial direction, an injection nozzle that sprays liquid from its tip toward the segment being transported, a pump unit that supplies liquid at a predetermined pressure to the injection nozzle via a liquid path, and a moving unit that cuts the segment by moving the tip of the injection nozzle from which the liquid is sprayed at a predetermined transverse speed in a direction transverse to the transport path.

[0008] Furthermore, a method for cutting segments for aerosol products according to one embodiment includes a segment transport step of transporting the segment along its axial direction in a transport path, a liquid injection step of injecting liquid from an injection nozzle toward the segment being transported, a nozzle moving step of moving the tip of the injection nozzle from which the liquid is injected at a predetermined transverse speed in a transverse direction with respect to the transport path, and a segment cutting step of cutting the segment being transported with the liquid injected from the moving tip.

[0009] According to the above embodiment, it is possible to reduce the production cost of aerosol products while ensuring the quality of the aerosol products.

[0010] This is a longitudinal cross-section of a segment. This is a transverse cross-section of a segment. This is a schematic diagram of a cutting device for cutting segments. This is a top view of a moving unit. This is a top view of a moving unit when cutting segments. This is a flowchart explaining the segment cutting method. This is a vector diagram showing the transport speed along the segment transport path and the velocity vector of the transverse velocity at the tip of the injection nozzle along the transport path. This is a mechanism diagram showing the segment transport path and the trajectory of the tip of the injection nozzle as seen from above.

[0011] The cutting device 10 and cutting method for the segment 1 used in aerosol products will be described below with reference to the drawings. Figure 1 shows a longitudinal section of the segment 1, and Figure 2 shows a cross-sectional view of the segment 1. The aerosol product (hereinafter also simply referred to as the article) is formed by joining a plurality of segments 1 with chipping paper (not shown). The segment 1 is, for example, an aerosol-generating segment filled with a filler 2 containing aerosol products, and is formed by wrapping the filler 2 with rolled paper 4. The filler 2 includes, for example, a crimped sheet impregnated with a fragrance liquid or tobacco extract, tobacco chips, fragrance particles, an aerosol substrate, etc., and generates an aerosol for the user to inhale when heated.

[0012] Figure 3 shows a schematic diagram of a cutting device 10 for cutting a segment 1. The segment 1 is formed by cutting a long or continuous segment 1, manufactured by a hoisting machine (not shown), to a predetermined length using the cutting device 10. The cutting device 10 includes a transport path 12, an injection nozzle 14, a pump unit 16, and a moving unit 18. The transport path 12 is formed as a guide with grooves that conform to the shape of the segment 1, and the segment 1 is transported while being pushed in from the upstream side along its axial direction A, with its movement restricted by the grooves. The transport path 12 may be formed as a cylindrical guide, or as a conveyor that transports the segment 1 itself. The injection nozzle 14 injects liquid L from the injection port 14b at the tip 14a of the injection nozzle 14 toward the segment 1 being transported. The transport path 12 has a passage opening 12a through which the liquid L injected from the injection port 14b passes.

[0013] Holding members 12b are provided above the upstream and downstream ends of the segment 1 in the transport direction of the passage opening 12a. Each holding member 12b holds the segment 1 toward the transport path 12 during transport so that the segment 1 does not spring up when it is cut. The pump unit 16 includes a pump 19 that discharges liquid L and a control unit 20 that controls the pressure of the liquid L, with the control unit 20 controlling the discharge pressure of the liquid L discharged from the pump 19. As a result, the pump unit 16 supplies liquid L at a predetermined pressure to the injection nozzle 14 via a liquid path 22 formed in a tube or the like. The liquid L is, for example, water, more specifically tap water, and a water jet pressurized to a predetermined high pressure is injected from the injection port 14b of the injection nozzle 14. The moving unit 18 is positioned between the liquid path 22 and the injection nozzle 14 and cuts the segment 1 by moving the tip 14a of the injection nozzle 14, from which the liquid L is injected, at a predetermined transverse speed in a transverse direction relative to the transport path 12.

[0014] The following describes the relationship between the range of parameters that can be changed when using the cutting device 10 and the cutting loss length ΔL when cutting segment 1. The diameter d of the injection port 14b formed at the tip 14a of the injection nozzle 14 is preferably 0.05 mm to 1.4 mm. The pressure P of the liquid L injected from the injection nozzle 14 is preferably 600 MPa or less. The contact time (in other words, cutting time) t of the liquid L with respect to segment 1 when cutting segment 1 is preferably 6 ms (milliseconds) to 12 ms. The distance D between the tip 14a of the injection nozzle 14 and segment 1 when cutting segment 1 is preferably 50 to 100 times the diameter d of the injection port 14b, and more preferably 60 to 80 times the diameter d of the injection port 14b.

[0015] By setting each parameter within these ranges, when segment 1 is cut with liquid L, a sharp cut surface 1a (see Figures 1 and 2) perpendicular to its axial direction A can be formed on segment 1. When segment 1 is cut with liquid L, a portion of the end of segment 1 near the cut surface 1a is lost. The length of this lost end of segment 1 in the axial direction A is defined as the cutting loss length ΔL, which is between 0.1 mm and 0.3 mm. By setting each of the above parameters within the above ranges, a sharp cut surface 1a perpendicular to the axial direction A can be formed on segment 1 with a small cutting loss length ΔL of 0.1 mm to 0.3 mm as described above. This significantly reduces material loss of segment 1. Furthermore, liquid L may contain additives that can impart various functions to segment 1. Additives include, for example, fragrance liquids and adhesive liquids (binders), and such additives are added to segment 1 via the cut surface 1a when segment 1 is cut.

[0016] Figure 4 shows a top view of the moving unit 18. The moving unit 18 in this embodiment includes a rod 24, a pair of pulleys 26, and a drive unit 28. Links 30 are attached to both ends of the rod 24 in its longitudinal direction, and the tip 14a of the injection nozzle 14 is held in the middle of the rod 24 in its longitudinal direction, specifically in the center of the longitudinal direction. By forming the liquid path 22 from a flexible tube or the like, continuous supply of liquid L from the pump unit 16 to the injection nozzle 14 is possible even while the injection nozzle 14 is moving. The pair of pulleys 26 are held on the outer circumference of the rod 24 at both ends via links 30. The drive unit 28 is, for example, a motor, which rotates at least one of the pair of pulleys 26 at a predetermined rotational speed via a drive shaft 32.

[0017] Figure 5 shows a top view of the moving unit 18 when cutting segment 1, and Figure 6 shows a flowchart illustrating the method of cutting segment 1. The method of cutting segment 1 will be explained below using Figures 4, 5, and 6. When the cutting of segment 1 is started, first, segment 1 is transported along its axial direction A on the transport path 12 (segment transport step S1). Next, liquid L is sprayed from the spray nozzle 14 towards the segment 1 while it is being transported (liquid spraying step S2). Next, as shown in Figure 4, the tip 14a of the spray nozzle 14 from which the liquid L is sprayed is moved at a predetermined transverse speed in the transverse direction relative to the transport path 12 (nozzle moving step S3). Note that the liquid spraying step S2 may be performed before the segment transporting step S1, or the segment transporting step S1 and the liquid spraying step S2 may be performed simultaneously.

[0018] More specifically, as shown in Figure 5, the moving unit 18 moves the tip 14a of the injection nozzle 14 toward the direction of transport of the segment 1 and at a predetermined transverse angle with respect to the transport path 12 by tilting a rod 24 that is linked to the rotation of a pair of pulleys 26. As a result, the liquid L injected from the moving tip 14a cuts the segment 1 while it is being transported (segment cutting step S4), completing the cutting at one point of the segment 1 and forming one segment 1. The liquid injection step S2 is performed continuously, and from there the segment cutting step S4 is also performed continuously and at high speed in accordance with the nozzle movement step S3. In addition, the liquid L contains additives as described above as needed. As a result, in the segment cutting step S4, various additives are added to the segment 1 via the cut surface 1a of the segment 1 when the segment 1 is cut (addition process P2).

[0019] Figure 7 shows a vector diagram representing the transport speed V1 of segment 1 in the transport path 12 and the velocity vector V2a of the transverse velocity V2 of the tip 14a of the injection nozzle 14 along the transport path 12. The tip 14a of the injection nozzle 14 moves toward the transport direction of segment 1 and with a predetermined transverse angle α with respect to the transport path 12 due to the tilting of the rod 24. Therefore, the transverse velocity V2 of the tip 14a of the injection nozzle 14 is decomposed into a velocity vector V2a that is along the transport path 12, in other words, in the same direction as the transport speed V1 of segment 1, and a velocity vector V2b that is perpendicular to the transport path 12.

[0020] In the nozzle movement step S3, the moving unit 18 adjusts the magnitude of the velocity vector V2a of the transverse velocity V2 of the tip 14a of the injection nozzle 14 along the transport path 12 to match the magnitude of the transport velocity V1 of the segment 1 in the transport path 12 (velocity control process P1). This velocity control process P1 is performed by controlling the rotational speed of a pair of pulleys 26 with the drive unit 28. In this way, even if the transverse direction of the tip 14a with respect to the transport path 12 is inclined, by matching the direction and magnitude of the velocity vector V2a and the transport velocity V1, the cut surface 1a of the segment 1 cut by the liquid L can be made perpendicular to the axial direction A, as shown in Figure 1.

[0021] Figure 8 shows a top view of the mechanism of the transport path 12 of segment 1 and the trajectory 34 of the tip 14a of the injection nozzle 14. The moving unit 18 moves the tip 14a of the injection nozzle 14 along a figure-eight trajectory 34 in a planar region including the radial surfaces 36 of the pair of pulleys 26 by tilting a rod 24 that is linked to the rotation of the pair of pulleys 26. The injection of liquid L from the injection nozzle 14 is performed continuously. First, the tip 14a crosses the transport path 12 from one side of the transport path 12, cutting segment 1. Next, as the trajectory 34 of the tip 14a becomes figure-eight, the tip 14a crosses the transport path 12 from the other side of the transport path 12, cutting the next segment 1. Furthermore, the tip 14a of the injection nozzle 14, in any of the directions in which the tip 14a crosses the transport path 12, is oriented toward the transport direction of the segment 1 and crosses the transport path 12 at a predetermined transverse angle α with respect to the transport path 12. Therefore, regardless of which of the above directions the segment 1 is cut from, the cut surface 1a of the segment 1 can be made perpendicular to the axial direction A.

[0022] As described above, the segment 1 cutting device 10 of this embodiment includes the transport path 12, injection nozzle 14, pump unit 16, and moving unit 18 mentioned above, and performs each of the steps S1 to S4 described above. This prevents the organic matter contained in the filler material 2 of segment 1 from oxidizing due to high temperature, as would occur when segment 1 is cut with laser light. Therefore, the taste of the aerosol product is not affected by the cutting of segment 1. In addition, consumables such as inert gas and cooling gas used with the laser light are not required, and strict control of such gases is also unnecessary. As a result, it is possible to reduce the production cost of the aerosol product while ensuring the quality of segment 1 and, by extension, the aerosol product containing it.

[0023] More specifically, the diameter d of the nozzle 14b at the tip 14a of the injection nozzle 14 is preferably 0.05 mm to 1.4 mm. The pressure P of the liquid L injected from the injection nozzle 14 is preferably 600 MPa or less. The contact time t of the liquid L with the segment 1 when cutting the segment 1 is preferably 6 ms to 12 ms. The distance D between the tip 14a and the segment 1 is preferably 50 to 100 times the diameter d of the nozzle 14b, and more preferably 60 to 80 times the diameter d of the nozzle 14b. By setting these parameters in the cutting device 10, the cutting loss length ΔL becomes 0.1 mm to 0.3 mm, resulting in less material loss during cutting and the formation of a sharp cut surface 1a on the segment 1.

[0024] Furthermore, the liquid L may contain additives, which are added to the segment 1 via the cut surface 1a during the addition process P2 of the segment cutting step S4 when the segment 1 is cut. This makes it possible to produce a variety of segment 1 variations with various functions, and consequently, aerosol products. The moving unit 18 also matches the magnitude of the velocity vector V2a of the transverse velocity V2 of the tip 14a of the injection nozzle 14 along the transport path 12 with the magnitude of the transport velocity V1 of the segment 1 in the transport path 12. This control is performed in the velocity control process P1 of the nozzle moving step S3, and this makes it possible to make the cut surface 1a of the segment 1 cut by the liquid L perpendicular to the axial direction A when the segment 1 is cut while being transported along the transport path 12. Therefore, it becomes possible to ensure the quality of the segment 1 and consequently the aerosol products more reliably.

[0025] More specifically, the moving unit 18 comprises the rod 24, a pair of pulleys 26, and a drive unit 28 as described above. The moving unit 18 moves the tip 14a of the injection nozzle 14 toward the conveying direction of the segment 1 and at a predetermined transverse angle α with respect to the conveying path 12 by tilting the rod 24, which is linked to the rotation of the pair of pulleys 26. As a result, the segment 1 can be continuously cut by moving the tip 14a with a relatively simple mechanism consisting of the rod 24 and the pair of pulleys 26.

[0026] Furthermore, the moving unit 18 moves the tip 14a of the injection nozzle 14 along a figure-eight trajectory 34 in a planar region including the radial surface 36 of the pair of pulleys 26 by tilting a rod 24 that is linked to the rotation of the pair of pulleys 26. This allows the tip 14a of the injection nozzle 14 to traverse the transport path 12 from both sides at a predetermined period, thereby enabling the segment 1 to be cut continuously and quickly to a predetermined length. Consequently, the cutting efficiency of the segment 1 can be increased, and the productivity of the segment 1, and thus the aerosol product, can be improved.

[0027] This concludes the description of the embodiments. However, the above embodiments are not limiting, and various modifications can be made without departing from the spirit of the present invention. For example, the above-described configuration of the mobile unit 18 is merely an example, and the segment 1 can be cut by moving the tip 14a of the injection nozzle 14 in a transverse direction with respect to the transport path 12 at a predetermined transverse speed, and the necessary operations can be achieved using a multi-axis articulated robot or a parallel link robot.

[0028] Furthermore, if the segment 1 to be cut is the aerosol-generating segment described above, it generates an aerosol from the filler 2 when heated. The aerosol-generating segment, and by extension the article, may be of the combustion-heating type or the non-combustion-heating type. In addition, segment 1 may be a functional segment wrapped with a filler having various functions other than aerosol generation, a mouthpiece segment filled with filter material, or a cooling segment having a hollow section.

[0029] Furthermore, the velocity vectors V2a and V2b can be calculated using the length and diameter d of segment 1, which are set as product specifications, and the aforementioned contact time (cutting time) t. Then, using the calculated velocity vectors V2a and V2b, it is possible to calculate the slope of the combined velocity vector, which is the transverse velocity V2, i.e., the transverse angle α of the injection nozzle 14 relative to segment 1. Therefore, under the conditions that the product specifications of segment 1 are uniform and the contact time t is constant, the transverse angle α can be calculated as a fixed value. This transverse angle α can be changed by configuring the drive shafts 32 of each pulley 26 to be spaced apart from each other and adjusting the distance D1 between the drive shafts 32 of each pair of pulleys 26 (see Figures 4 and 5).

[0030] Specifically, shortening the distance D1 between the axes of each pulley 26 changes the transverse angle α to be acute with respect to the transport path 12, and lengthening the distance D1 changes the transverse angle α to be obtuse with respect to the transport path 12. Therefore, in order to make the cut surface 1a of the segment 1 a plane perpendicular to the axial direction A, the transverse angle α may be controlled by adjusting the distance D1 between the axes of each pulley 26 (see distance control process P3, Figure 6). When the distance control process P3 is performed, the speed control process P1 described above is performed solely for the purpose of making the segment cutting step S1 follow the transport speed V1 of the segment 1.
