- the mixture M contains granular charcoal, a binder, calcium carbonate, and water as main components.
- sodium alginate or carboxymethyl cellulose (CMC) can be used as the binder, and the water content of the mixture M is 20 to 60 wt% or more.
- the extrusion molding machine 10 extrudes the mixture M as a circular rod member R while kneading the mixture M, and sends the molded rod member R along a horizontal delivery line DL extending from the outlet 12 of the extrusion molding machine 10.
- the rod member R has a hollow shape as shown in FIG.
- the rod member R may have a hollow shape such as a honeycomb structure or a lattice structure, or may be solid.
- a transfer conveyor 14 is horizontally disposed downstream of the delivery line DL, and a predetermined interval corresponding to the length of the delivery line DL is secured between the transfer conveyor 14 and the extrusion molding machine 10. Therefore, the transfer conveyor 14 is connected to the extruder 10 via the delivery line DL and forms an extension of the delivery line DL.
- the transfer conveyor 14 is a belt conveyor having a silicone flat belt.
- the transfer conveyor 14 described above receives the rod member R from the delivery line DL, and transports the received rod member R in the same direction as the delivery direction.
- a measurement position MP is defined on the delivery line DL.
- the measurement position MP divides the delivery line DL into an upstream section U DL on the extruder 10 side and a downstream section DD L on the transfer conveyor 14 side.
- the measuring device 16 is arranged at the measurement position MP, and the measuring device 16 measures the outer diameter of the rod member R when the rod member R passes the measurement position MP.
- the measuring device 16 includes a light source 16a disposed below the delivery line DL and an outer diameter sensor 16b disposed with the delivery line DL interposed between the light source 16a.

At this time, the laser light passes through an interval secured between the upstream section U DL and the downstream section D DL .
- the outer diameter sensor 16b is not particularly limited, but it is desirable that the outer diameter of the rod member R can be measured with high accuracy. For example, it is desirable that the outer diameter sensor 16b has a resolution higher than 1/100 mm.
- the rod member R When the rod member R is continuously sent on the delivery line DL, the rod member R blocks a part of the laser light from the light source 16a, and the outer diameter sensor 16b receives only the remaining part of the laser light. Therefore, the outer diameter sensor 16b on the basis of the part of the laser light is blocked by the rod member R (part of the cathode), it can be measured outside diameter D R of the rod member R.
- the outer diameter D R (measurement result) measured in this way is given to the control device 18 from the outer diameter sensor 16b, that is, the measuring device 16.
- the control device 18 is electrically connected to a speed control motor 20 that drives the transfer conveyor 14, and a servo motor or an inverter motor can be used as the speed control motor 20.
- a cutting section 22 and a post drying section 24 are sequentially arranged downstream of the transfer conveyor 14.
- the cutting section 22 cuts the rod member R every predetermined length, and forms a cylindrical carbon heat source from the rod member R.
- the post-drying section 24 receives carbon heat sources from the cutting section 22 and dries these carbon heat sources. After such post-drying treatment, the carbon heat source is stored.
- such a carbon heat source is used as a carbon heat source for the filter cigarette.
- the diameter of the carbon heat source that is, the outer diameter DR of the rod member R is about 6 to 8 mm.
- the upstream section U DL of the delivery line DL described above are further divided and pre-drying zone A D, in a conveyor zone A C.
- Predrying zone A D is placed into the extruder 10 side, whereas, the conveyor region A C is located at the measurement position MP side.
- the predrying area AD is provided with a blower 26 as a predrying device. The blower 26 is disposed below the delivery line DL and generates a wind toward the delivery line DL.
- the above-described wind has such a temperature that the water contained in the rod member R is not rapidly evaporated, that is, the outer surface of the rod member R is prevented from being dried rapidly. If blown, the wind reduces the stickiness of the outer surface of the rod member R.
- the rod member R immediately after being extruded by the extruder 10 is in a state of being cooled to about 20 ° C., for example.
- Basin directly above the conveyor zone A C is at least measuring device 16, i.e., over a pre-drying zone A D to the measuring device 16 is secured, it is formed by the first roller conveyor 28.
- the first roller conveyor 28 includes a plurality of rollers, these rollers predetermined intervals along the delivery line DL, for example adjacent to exist the pitch P 1, it is rotatably supported.
- the downstream section D DL described above is formed by the second roller conveyor 30.
- the second roller conveyor 30 is also a number of rollers, the rollers are adjacent to exist a pitch P 2 along the delivery line DL, and is rotatably supported.
- the pitch P 2 on the second roller conveyor 30 is shorter than the pitch P 1 on the first roller conveyor 28.
- the outer diameter D R of the rod member R as described above is about 6 ⁇ 8 mm
- the rollers of the first roller conveyor 28 has a diameter of, for example, 6 ⁇ 8 mm
- the second roller conveyor 30 Each roller has a diameter smaller than the roller diameter of the first roller conveyor 28, for example, a diameter of about 2 mm.
- the pitches P 1 and P 2 are set to be equal to or smaller than the outer diameter DR of the rod member R.
- the length of the conveyor area AC and the downstream section D DL along the delivery line DL is the same (for example, about 120 mm), and the number of rollers in the second roller conveyor 30 is the number of rollers in the first roller conveyor 28. More than the number of This means that the second roller conveyor 30 provides a larger number of support points for the rod member R than the first roller conveyor 28, and the distance (pitch P 2 ) between these support points is the first roller conveyor. It means that it is smaller than the interval between the support points at 28 (pitch P 1 ).
- the second roller conveyor 30 can support the rod member R at a larger number of support points than the first roller conveyor 28, the rod member R is measured after the diameter of the rod member R is measured at the measurement position MP. This is suitable for enabling highly accurate feedback control with respect to the transfer speed of the transfer conveyor 14.
- the rollers of the first and second roller conveyors 28 and 30 are made of stainless steel such as JIS standards SUS316 and SUS304, for example.
- SUS316 is superior in corrosion resistance compared to SUS304, it is suitable for the rollers of the first and second roller conveyors 28 and 30.
- the roller may have a coating that reduces sticking of the rod member R, which may be, for example, a fluorine coating, a silicone coating, a diamond-like coating (DLC), or a combination of these coatings. it can.
- the roller when the roller has the above-described coating, the roller may be formed of a resin material to which the rod member R is difficult to adhere, such as polyacetal resin (POM) or polyether ketone resin (PEEK), in addition to the above-described stainless steel. Good.
- POM polyacetal resin
- PEEK polyether ketone resin
- the extruder 10 When the extruder 10 is driven, the extruder 10 extrudes the rod member R from the mixture M, and sends the rod member R along the delivery line DL (molding step). On the other hand, simultaneously with the driving of the extrusion molding machine 10, the transfer conveyor 14 is also driven. At this time, the transfer speed of the transfer conveyor 14 coincides with the feed speed of the rod member R.
- the moisture content of the mixture M that is, the moisture content of the rod member R immediately after the extrusion molding is relatively high, and the shape retention of the rod member R at this time is low. For this reason, if the rod member R is directly received by the transfer conveyor 14 from the extrusion molding machine 10, the rod member R will be plastically deformed on the transfer conveyor 14, and the roundness of the rod member R is not guaranteed.
- the rod member R immediately after the extrusion molding is sent to the delivery line DL before being received by the transfer conveyor 14. Is sent along.
- Such a feeding process of the rod member R advances the pre-drying of the outer peripheral surface of the rod member R, improves the shape retention of the rod member R, and reduces the stickiness of the outer surface of the rod member R.
- the upstream section U DL of the delivery line DL includes a pre-drying area AD that promotes drying of the rod member R, and the pre-drying area AD is disposed adjacent to the extruder 10. . Therefore, the rod member R immediately after the extrusion molding first passes through the pre-drying area AD , and at this time, the wind of the blower 26 is blown onto the rod member R from below (drying process). Such a wind promotes pre-drying of the peripheral surface region of the lower half of the rod member R, that is, the bottom portion of the rod member R, so that the shape retaining property of the bottom portion of the rod member R is particularly high.
- the blowing of wind promotes pre-drying, particularly for the lower half peripheral surface region of the rod member R.
- pre-drying here is local solidification of the rod member R, that is, the rod member R is It does not cause uneven shrinkage, and no cracks are generated in the rod member R. Therefore, even if the rod member R enters the first roller conveyor 28 downstream of the pre-drying area AD and the bottom of the rod member R is supported by each roller of the first roller conveyor 28, the rod member R Without undergoing plastic deformation, the roundness of the rod member R is ensured.
- the outer diameter DR of the rod member R is measured by the measuring device 16, and the feeding of the rod member R is taken over from the first roller conveyor 28 to the second roller conveyor 30. It is.
- the pitch P 1, P 2 of the rollers in the first and second roller conveyors 28 and 30 as described above is less than the outer diameter D R of the rod member R, delivered rod member R is along the delivery line DL when it is, the rod member R is at its outside diameter D R intervals less than sequentially contacts the respective rollers of the first and second roller conveyors 28 and 30.
- the rod member R moves on the first and second roller conveyors 28 and 30
- the rod member R does not drop or meander between the rollers, and the straightness of the rod member R is improved. It is guaranteed that the rod member R can move smoothly on the first and second roller conveyors 28 and 30.
- the feeding of the rod member R is taken over from the second roller conveyor 30 to the transfer conveyor 14, and is transferred by the transfer conveyor 14 toward the subsequent cutting section 22 and the post drying section 24, and the above-described cutting and post drying processing is performed. receive.
- the rod member R is only pre-dried to such an extent that only the outer peripheral surface of the bottom portion is not cured, the distribution of the moisture content in the rod member R may be greatly biased when viewed from the cross section of the rod member R. Absent. Therefore, even if the carbon heat source is subjected to a post drying process in the post-drying section 24 at the subsequent stage, the carbon heat source is not cracked and the roundness of the carbon heat source is not reduced.
- the belt of the transfer conveyor 14 is made of silicone, while the rollers of the first and second roller conveyors 28 and 30 are made of the aforementioned stainless steel. Low. Therefore, since the rod member R is difficult to adhere to the rollers of the first and second roller conveyors 28 and 30 and the belt of the transfer conveyor 14, the rod member R is attached to the first and second roller conveyors 28 and 30 and the transfer conveyor 14. Thus, the conveyors 28, 30, and 14 can pass smoothly without being caught.
- the second roller conveyor 30 is compared with the first roller conveyor 28 as derived from the length of the conveyor area AC and the downstream section D DL and the magnitude relationship between the pitches P 1 and P 2.
- a number of rollers are included, and the rod member R can be supported at a number of support points. This means that the period in which each roller of the second roller conveyor 30 contacts the rod member R is shorter than the period in which each roller of the first roller conveyor 28 contacts the rod member R, and the rod member R is stable. Contributes to sending.
- the second roller conveyor 30, to be used for delivery of the rod member R immediately after the outer diameter D R of the rod member R is measured relates transfer speed of the transfer conveyor 14, the feedback control described later with high precision
- stable feeding of the rod member R by the second Laurent bear 30 is important.
- step S1 it is determined whether or not the extruder 10 and the transfer conveyor 14 are driven (step S1). If the determination result here is true (Yes), the rod member R measured by the measuring device 16 is determined. outer diameter D R is read (step S2).
- the outer diameter D R is determined whether the maximum allowable diameter D MAX or more (step S3), and if the result of this determination is true, by the following equation, the outer diameter D from the maximum allowable diameter D MAX A deviation ⁇ D of R is calculated (step S4).
- ⁇ D D R -D MAX
- the control device 18 calculates a speed control amount ⁇ V for increasing or decreasing the transfer speed of the transfer conveyor 14 (step S7), and thereafter directs the speed control amount ⁇ V to the servo motor 20. (Step S8).
- the servo motor 20 changes the transfer speed of the transfer conveyor 14 based on the speed control amount ⁇ V. Specifically, the outer diameter D R is if more than the maximum allowable diameter D MAX, the transfer speed of the transfer conveyor 14 is increased. In this case, the transfer conveyor 14 is transported while pulling the rod member R sent from the extruder 10, thereby, the outer diameter D R of the rod member R is decreased with the plastic deformation of the rod member R.
- the transfer speed of the transfer conveyor 14 is reduced.
- the transfer conveyor 14 acts to damp the delivery rate of the rod member R from extruder 10
- an outer diameter D R of the rod member R increases with plastic deformation of the rod member R.
- Variation of the outer diameter D R of the rod member R is generated by varying the delivery rate of the rod member R from extruder 10, the results of the outer diameter D R is feedback controlled as described above, the outer diameter D R is maintained in an allowable range between the maximum allowable diameter DMAX and the minimum allowable diameter DMIN .
- the feedback control described above does not change the driving speed of the extrusion molding machine 10, that is, the kneading speed of the mixture M, so that the kneading conditions become constant and contribute to the stability of the bulk density and hardness of the rod member R.

Description
ロッド部材を成形して押し出す押出成形機と、
押出成形機から押し出されたロッド部材を受け取る送出ラインと、
送出ラインからロッド部材を受け取り、受け取ったロッド部材を移送する移送コンベアと、
ロッド部材が送出ライン上に規定された測定位置を通過するとき、ロッド部材の外径を測定し、測定結果を出力する測定装置と、
測定装置の測定結果に基づき、移送コンベアによるロッド部材の移送速度をフィードバック制御する制御装置と
を具備し、
送出ラインを測定位置にて押出成型機側の上流セクションと移送コンベア側の下流セクションとに区分してみたとき、前記送出ラインは、
少なくとも測定装置の直上流にて上流セクションの一部を形成し、ロッド部材の送出を案内する第1ローラコンベアと
下流セクションを形成し、ロッド部材の送出を案内する第2ローラコンベアと
を含んでいる。
一方、送出ラインに沿いロッド部材が送出される過程に、ロッド部材の外径が測定装置により測定され、ここでの測定結果にもとづき、移送コンベアによるロッド部材の移送速度がフィードバック制御される。
本発明の押出成形システム及び方法の具体的な形態は後述の説明から明らかとなる。
送出ラインDL上には測定位置MPが規定されており、この測定位置MPは送出ラインDLを押出成形機10側の上流セクションUDLと移送コンベア14側の下流セクションDDLとに区分する。
なお、外径センサ16bは特に限定されないが、ロッド部材Rの外径を高精度に測定できることが望ましい。例えば、外径センサ16bは1/100mmよりも高い分解能を有しているのが望ましい。
更に、本実施形態では、ピッチP1,P2はロッド部材Rの外径DR以下に設定されている。
押出成形機10が駆動されれば、押出成形機10は混合物Mからロッド部材Rを押出成形し、このロッド部材Rを送出ラインDLに沿って送出させる(成形工程)。一方、押出成形機10の駆動と同時に、移送コンベア14また駆動される。このとき、移送コンベア14の移送速度はロッド部材Rの送出速度に一致している。
それ故、プレ乾燥域ADの下流にて、ロッド部材Rが第1ローラコンベア28に進入し、ロッド部材Rの底部が第1ローラコンベア28の各ローラに支持されても、ロッド部材Rは塑性変形を受けることがなく、ロッド部材Rの真円性が担保される。
先ず、押出成形機10及び移送コンベア14が駆動されているか否かが判別され(ステップS1)、ここでの判別結果が真(Yes)の場合、測定装置16にて測定されたロッド部材Rの外径DRが読み込まれる(ステップS2)。
ΔD=DR-DMAX
ΔD=DMIN-DR
なお、ステップS5の判別結果が偽の場合、ステップS1以降のステップが繰り返して実施され、また、ステップS1の判別結果が偽の場合、図3の制御ルーチンは終了する。
ロッド部材Rにおける外径DRの変動は押出成形機10からのロッド部材Rの送出速度が変動することで発生するが、上述したように外径DRがフィードバック制御される結果、外径DRは最大許容径DMAXと最小許容径DMINとの間の許容範囲に維持される。
また、フィードバック制御の実施にあたり、移送コンベア14のベルト及び第1及び第2ローラコンベア28,30の各ローラは、前述したようにロッド部材Rが粘着し難い材料から形成され、一方、ロッド部材Rの底部は予め乾燥処理され、底部の保形性は高い。
例えば、図4に示されるように測定装置16は第1及び第2ローラコンベア28,30の直上に配置されていてもよい。この場合、光源16a及び外径センサ16bはロッド部材Rの送出ラインDLを挟み且つ水平方向に互いに離間して配置されている。
また、第2ローラコンベア30の各ローラは第1ローラコンベア28の各ローラの直径と同一の直径を有していてもよい。
