It is arranged along the direction of the slit groove 231 while leaving. According to this, by adjusting the suction and release of air for each suction hole group 232A, it is possible to easily and reliably control the attachment and detachment of the work W to and from the peripheral surface 21a of the drum 21.

前記吸引孔群２３２Ａは、複数のスリット溝２３１の隣り合うもの同士において、ドラム２１の回転軸Ｘに平行な幅方向に並んで配置されている。これによれば、ドラム２１の幅方向に沿って、ワークＷをドラム２１の周面２１ａに一斉に貼着させたり、あるいはドラム２１の周面２１ａから一斉に引き離したりすることができる。   The suction hole group 232 </ b> A is arranged side by side in a width direction parallel to the rotation axis X of the drum 21 between adjacent ones of the plurality of slit grooves 231. According to this, the work W can be stuck to the peripheral surface 21a of the drum 21 all at once or separated from the peripheral surface 21a of the drum 21 all at once along the width direction of the drum 21.

また、前記貼着機構２３は、図２または図３に示すように、ドラム２１の各吸引孔２３２に連通する複数の共通流路２３４と、共通流路２３４に連通する吸引流路２３５および供給流路２３６とを備え、これら共通流路２３４、吸引流路２３５および供給流路２３６で一組のエア流路２３３を構成して、複数組のエア流路２３３がドラム２１の周方向に沿って並んで配置されている。   Further, as shown in FIG. 2 or FIG. 3, the sticking mechanism 23 includes a plurality of common flow paths 234 communicating with the suction holes 232 of the drum 21, a suction flow path 235 communicating with the common flow path 234, and a supply path.

前記貼着機構２３は、図２〜図５に示すように、ドラム２１の外部において、吸引流路２３５に連通可能な吸引口２３７ａと、供給流路２３６に連通可能な第１供給口２３７ｂおよび第２供給口２３７ｃとを有するエア切替部材２３７を備える。このエア切替部材２３７は、ドラム２１と独立して設けられており、ドラム２１がエア切替部材２３７に摺動しながら軸回転するものとなされている。   As shown in FIGS. 2 to 5, the sticking mechanism 23 has, outside the drum 21, a suction port 237 a that can communicate with the suction channel 235, a first supply port 237 b that can communicate with the supply channel 236, and An air switching member 237 having a second supply port 237c is provided. The air switching member 237 is provided independently of the drum 21, and the shaft is rotated while the drum 21 slides on the air switching member 237.

前記吸引口２３７ａは、図２に示すように、ドラム２１の周面２１ａからワークＷを貼着する範囲Ｐに対応する位置に形成され、本実施形態では、吸引流路２３５に対応するドラム２１の径方向の位置であって、ドラム２１の軸回転の最上点から最下点までドラム２１の周方向に延びる態様の長孔に形成されている。   As shown in FIG. 2, the suction port 237a is formed at a position corresponding to a range P where the workpiece W is adhered from the peripheral surface 21a of the drum 21, and in the present embodiment, the drum 21 corresponding to the suction flow path 235 is formed. In the radial direction of the drum 21 and is formed in a long hole extending in the circumferential direction of the drum 21 from the uppermost point to the lowermost point of the axial rotation of the drum 21.

前記第１供給口２３７ｂは、図２に示すように、ドラム２１の周面２１ａからワークＷの前部を引き離す範囲Ｓ１に対応する位置に形成され、本実施形態では、供給流路２３６に対応するドラム２１の径方向の位置であって、ドラム２１の軸回転の最下点でドラム２１の周方向に延びる態様の長孔に形成されている。   As shown in FIG. 2, the first supply port 237b is formed at a position corresponding to a range S1 in which the front part of the work W is separated from the peripheral surface 21a of the drum 21, and in the present embodiment, corresponds to the supply flow path 236. It is formed in a long hole that extends in the circumferential direction of the drum 21 at the lowest point of the shaft rotation of the drum 21 at a position in the radial direction of the drum 21.

前記第２供給口２３７ｃは、図２に示すように、ドラム２１の周面２１ａからワークＷの後部を引き離す範囲Ｓ２に対応する位置に形成され、本実施形態では、供給流路２３６に対応するドラム２１の径方向の位置であって、第１供給口２３７ｂに対してドラム２１の軸回転方向の後方側においてドラム２１の周方向に延びる態様の長孔に形成されている。   As shown in FIG. 2, the second supply port 237c is formed at a position corresponding to a range S2 in which the rear part of the work W is separated from the peripheral surface 21a of the drum 21, and in the present embodiment, corresponds to the supply flow path 236. A long hole extending in the circumferential direction of the drum 21 at a position in the radial direction of the drum 21 and on the rear side in the axial rotation direction of the drum 21 with respect to the first supply port 237b.

また、前記貼着機構２３は、図５（ｂ）に示すように、ドラム２１の外部において、エア切替部材２３７の吸引口２３７ａと連通する吸引通路２３８ａと、エア切替部材２３７の第１供給口２３７ｂに連通する第１供給通路２３８ｂと、エア切替部材２３７の第２供給口２３７ｃに連通する第２供給通路２３８ｃとを有するエア通路部材２３８を備える。このエア通路部材２３８は、エア切替部材２３７に固定されており、吸引通路２３８ａ、第１供給通路２３８ｂおよび第２供給通路２３８ｃが配管およびバルブを介して図示略のポンプに接続されている。   Further, as shown in FIG. 5B, the sticking mechanism 23 includes a suction passage 238 a communicating with the suction port 237 a of the air switching member 237 outside the drum 21, and a first supply port of the air switching member 237. An air passage member 238 having a first supply passage 238b communicating with the air supply member 237b and a second supply passage 238c communicating with the second supply port 237c of the air switching member 237 is provided. The air passage member 238 is fixed to the air switching member 237, and the suction passage 238a, the first supply passage 238b, and the second supply passage 238c are connected to a pump (not shown) via a pipe and a valve.

而して、ドラム２１が軸回転すると、それに伴って各エア流路２３３がドラム２１の周方向に回転していき、ドラム２１の周面２１ａからワークＷを貼着する範囲Ｐにエア流路２３３が位置する間、該エア流路２３３の吸引流路２３５がエア切替部材２３７の吸引口２３７ａに連通した状態となる。また、ドラム２１ａからワークＷの前部を引き離す範囲Ｓ１にエア流路２３３が位置する間、該エア流路２３３の供給流路２３６がエア切替部材２３７の第１供給口２３８ｂに連通した状態となる。また、ドラム２１ａからワークＷの後部を引き離す範囲Ｓ２にエア流路２３３が位置する間、該エア流路２３３の供給流路２３６がエア切替部材２３７の第２供給口２３８ｃに連通した状態となる。   When the drum 21 rotates axially, each air flow path 233 rotates in the circumferential direction of the drum 21, and the air flow path extends from the peripheral surface 21 a of the drum 21 to the range P where the work W is adhered. While the 233 is located, the suction flow path 235 of the air flow path 233 is in communication with the suction port 237 a of the air switching member 237. Further, while the air flow path 233 is located in the range S1 in which the front portion of the work W is separated from the drum 21a, the supply flow path 236 of the air flow path 233 communicates with the first supply port 238b of the air switching member 237. Become. Further, while the air flow path 233 is located in the range S2 where the rear part of the work W is separated from the drum 21a, the supply flow path 236 of the air flow path 233 is in communication with the second supply port 238c of the air switching member 237. .

よって、ワークＷを搬送機構１からドラム装置２に受け渡す際、図示略のポンプによりエア通路部材２３８の吸引通路２３８ａを介してエア切替部材２３７の吸引口２３７ａから空気を吸引すると、該吸引口２３７ａに連通している吸引流路２３５を介して共通流路２３４の空気が吸引される。このため、該共通流路２３４に連通している幅方向に並んだ吸引孔群２３２Ａの各吸引孔２３２から空気が吸引され、該各吸引孔群２３２Ａの位置に対応するスリット溝２３１の内側空間Ｕに負圧が生じるため、ワークＷの表面をドラム２１の周面２１ａに貼着させることができる。   Therefore, when the work W is transferred from the transport mechanism 1 to the drum device 2, when air is sucked from the suction port 237a of the air switching member 237 through the suction passage 238a of the air passage member 238 by a pump (not shown), the suction port The air in the common flow path 234 is sucked through the suction flow path 235 communicating with the 237a. Therefore, air is sucked from each suction hole 232 of the suction hole group 232A arranged in the width direction communicating with the common flow path 234, and the inner space of the slit groove 231 corresponding to the position of each suction hole group 232A. Since a negative pressure is generated in U, the surface of the work W can be adhered to the peripheral surface 21a of the drum 21.

また、ワークＷを積層機構３まで回転搬送したあと、ドラム２１の周面２１ａからワークＷの前部をドラム２１の径方向に引き離す際、エア通路部材２３８の第１供給通路２３８ｂを介してエア切替部材２３７の第１供給口２３７ｂから空気を供給すると、該第１供給口２３７ｂに連通している供給流路２３６を介して共通流路２３４に空気が供給される。このため、該共通流路２３４に連通している幅方向に並んだ吸引孔群２３２Ａの各吸引孔２３２から空気を吐出され、該吸引孔２３２の位置に対応するスリット溝２３１の内側空間Ｕの負圧が解除されるため、ドラム２１の周面２１ａからワークＷの前部を引き離すことができる。   Further, after the work W is rotatably conveyed to the stacking mechanism 3, when the front part of the work W is separated from the peripheral surface 21 a of the drum 21 in the radial direction of the drum 21, air is supplied through the first supply passage 238 b of the air passage member 238. When air is supplied from the first supply port 237b of the switching member 237, air is supplied to the common flow path 234 via the supply flow path 236 communicating with the first supply port 237b. For this reason, air is discharged from each suction hole 232 of the suction hole group 232A arranged in the width direction communicating with the common flow channel 234, and the inner space U of the slit groove 231 corresponding to the position of the suction hole 232 is discharged. Since the negative pressure is released, the front portion of the work W can be separated from the peripheral surface 21a of the drum 21.

さらに、ドラム２１の周面２１ａからワークＷの前部を引き離した直後、ドラム２１の周面２１ａからワークＷの後部をドラム２１の径方向に引き離す際、エア通路部材２３８の第１供給通路２３８ｂを介してエア切替部材２３７の第２供給口２３７ｃから空気を供給すると、該第２供給口２３７ｃに連通している供給流路２３６を介して共通流路２３４に空気が供給される。このため、該共通流路２３４に連通している幅方向に並んだ吸引孔群２３２Ａの各吸引孔２３２から空気を吐出され、該吸引孔２３２の位置に対応するスリット溝２３１の内側空間Ｕの負圧が解除されるため、ドラム２１の周面２１ａからワークＷの回転方向の後部を引き離すことができる。   Further, immediately after the front portion of the work W is separated from the peripheral surface 21a of the drum 21 and when the rear portion of the work W is separated in the radial direction of the drum 21 from the peripheral surface 21a of the drum 21, the first supply passage 238b of the air passage member 238 is formed. When air is supplied from the second supply port 237c of the air switching member 237 via the, the air is supplied to the common flow path 234 via the supply flow path 236 communicating with the second supply port 237c. For this reason, air is discharged from each suction hole 232 of the suction hole group 232A arranged in the width direction communicating with the common flow channel 234, and the inner space U of the slit groove 231 corresponding to the position of the suction hole 232 is discharged. Since the negative pressure is released, the rear part in the rotation direction of the work W can be separated from the peripheral surface 21a of the drum 21.

なお、本実施形態では、ワークＷの前部を回転搬送方向の前半分とし、ワークＷの後部を回転搬送方向の後半分としている。   In the present embodiment, the front part of the work W is the front half in the rotational conveyance direction, and the rear part of the work W is the rear half in the rotational conveyance direction.

前記積層機構３は、ドラム装置２により回転搬送されてきたワークＷを順次積層する積層テーブル３１を備え、制御部１００により図示略の駆動装置を介して、ワークＷが積層されるごとに徐々に下方に移動したり、平面方向に移動または回転することによりワークＷの位置や姿勢を調整し得るものとなされている。   The laminating mechanism 3 includes a laminating table 31 for sequentially laminating the works W rotationally conveyed by the drum device 2. The laminating table 31 is gradually controlled by the control unit 100 via a driving device (not shown) every time the works W are laminated. The position and posture of the work W can be adjusted by moving the work W downward, or moving or rotating in the plane direction.

また、前記積層テーブル３１は、ワークＷの回転搬送方向の前側位置に爪部材３２が設けられている。この爪部材３２は、ワークＷが積層されるごとに上方に移動したり、平面方向に回転することにより、ワークＷの前側端部を受け止めるものとなされている。なお、ワークＷを積層テーブル３１に積層したあと、ワークＷの後側端部を抑える爪部材が設けられてもよい。   The stacking table 31 is provided with a claw member 32 at a position on the front side in the rotational conveyance direction of the work W. The claw member 32 receives the front end of the work W by moving upward or rotating in the plane direction each time the work W is stacked. In addition, after the work W is stacked on the stacking table 31, a claw member for suppressing the rear end of the work W may be provided.

前記制御部１００は、図６に示すように、搬送機構１の搬送動作、ドラム装置２の回転搬送動作、積層機構３の積層動作などを制御する。   As shown in FIG. 6, the control unit 100 controls the transport operation of the transport mechanism 1, the rotary transport operation of the drum device 2, the laminating operation of the laminating mechanism 3, and the like.

次に本装置によるワークＷの積層方法について図７を参照しつつ説明する。   Next, a method of laminating the work W by the present apparatus will be described with reference to FIG.

まず、ワークＷは、第１の搬送機構１１の上側のベルトコンベア１１ｂに他方の表面（下面）を向けて載置されたあと、該上側のベルトコンベア１１ｂの移動に従って搬送方向の下流側に向けて順次搬送される。そして、ワークＷは、第１の搬送機構１１の下流側端部に到達した際、第２の搬送機構１２の下側のコンベアベルト１２ｃに一方の表面（上面）を貼着により保持されたあと、該下側のベルトコンベア１２ｃの移動に従って搬送方向の下流側に向けて天吊り状態で順次搬送される。   First, the workpiece W is placed on the upper belt conveyor 11b of the first transport mechanism 11 with the other surface (lower surface) facing the other side, and then directed to the downstream side in the transport direction according to the movement of the upper belt conveyor 11b. Transported sequentially. Then, when the work W reaches the downstream end of the first transport mechanism 11, after one surface (upper surface) is held on the lower conveyor belt 12 c of the second transport mechanism 12 by sticking. In accordance with the movement of the lower belt conveyor 12c, they are sequentially conveyed in a suspended state toward the downstream side in the conveying direction.

次に、ワークＷは、図７（ａ）に示すように、第２の搬送機構１２により搬送方向に搬送される過程において、他方の表面が上流側のドラム装置２のドラム２１の周面２１ａに貼着される。   Next, as shown in FIG. 7A, in the process of being transported in the transport direction by the second transport mechanism 12, the other surface is the peripheral surface 21 a of the drum 21 of the upstream drum device 2, as shown in FIG. Affixed to

具体的には、ワークＷの前端部がドラムの最上点に到達した際、図示略のポンプによりエア通路部材２３８の吸引通路２３８ａを介してエア切替部材２３７の吸引口２３７ａから空気を吸引すると、該吸引口２３７ａに連通している吸引流路２３５を介して共通流路２３４の空気も吸引される。このため、該共通流路２３４に連通している幅方向に並んだ吸引孔群２３２Ａの各吸引孔２３２から空気が吸引され、該各吸引孔群２３２Ａの位置に対応するスリット溝２３１の内側空間Ｕに負圧が生じるため、ドラム２１の周面２１ａにワークＷが順次貼着される。   Specifically, when the front end of the work W reaches the uppermost point of the drum, when air is sucked from the suction port 237a of the air switching member 237 through the suction passage 238a of the air passage member 238 by a pump (not shown), The air in the common channel 234 is also sucked through the suction channel 235 communicating with the suction port 237a. Therefore, air is sucked from each suction hole 232 of the suction hole group 232A arranged in the width direction communicating with the common flow path 234, and the inner space of the slit groove 231 corresponding to the position of each suction hole group 232A. Since a negative pressure is generated in U, the work W is sequentially adhered to the peripheral surface 21a of the drum 21.

次に、ワークＷは、図７（ｂ）に示すように、ドラム２１の周面２１ａに他方の表面が貼着された状態において、ドラム２１が軸回転するのに伴って、一方の表面と他方の表面で表裏を反転しながら下方の積層機構３まで１８０度の回転位相で回転搬送される。   Next, as shown in FIG. 7 (b), the work W is brought into contact with one surface with the rotation of the drum 21 while the other surface is adhered to the peripheral surface 21a of the drum 21. While being turned upside down on the other surface, the sheet is rotated and conveyed to the lower stacking mechanism 3 with a rotation phase of 180 degrees.

具体的には、図示略のポンプによりエア通路部材２３８の吸引通路２３８ａを介してエア切替部材２３７の吸引口２３７ａから空気を吸引し続けると、該吸引口２３７ａに連通している吸引流路２３５を介して共通流路２３４の空気も吸引され続ける。このため、該共通流路２３４に連通している幅方向に並んだ吸引孔群２３２Ａの各吸引孔２３２から空気が吸引され続け、該各吸引孔群２３２Ａの位置に対応するスリット溝２３１の内側空間Ｕに負圧が生じる続けるため、ワークＷはドラム２１の周面２１ａに貼着した状態を維持しながら回転搬送される。   Specifically, if air is continuously sucked from the suction port 237a of the air switching member 237 through the suction path 238a of the air path member 238 by a pump (not shown), the suction flow path 235 communicating with the suction port 237a is provided. , The air in the common flow path 234 is also continuously sucked. For this reason, air is continuously sucked from the suction holes 232 of the suction holes 232A arranged in the width direction communicating with the common flow channel 234, and the inside of the slit groove 231 corresponding to the position of each suction holes 232A. Since the negative pressure continues to be generated in the space U, the work W is rotated and conveyed while maintaining the state of being adhered to the peripheral surface 21a of the drum 21.

次に、ワークＷは、図７（ｃ）（ｄ）に示すように、ドラム２１の周面２１ａから引き離されることにより、爪部材３２で前側端部を受け止められつつ、積層機構３の積層テーブル３１に一方の表面を向けながら積層される。   Next, as illustrated in FIGS. 7C and 7D, the work W is separated from the peripheral surface 21 a of the drum 21, so that the claw member 32 receives the front end portion of the work W, and the work table W of the stacking mechanism 3. It is laminated with one surface facing 31.

具体的には、図７（ｃ）に示すように、ワークＷの前端部がドラム２１の最下点付近に到達した際、図示略のポンプによりエア通路部材２３８の第１供給通路２３８ｂを介してエア切替部材２３７の第１供給口２３７ｂから空気を供給すると、該第１供給口２３７ｂに連通している供給流路２３６を介して共通流路２３４に空気が供給される。このため、該共通流路２３４に連通している幅方向に並んだ吸引孔群２３２Ａの各吸引孔２３２から空気が吐出され、該各吸引孔群２３２Ａの位置に対応するスリット溝２３１の内側空間Ｕの負圧が解除されるため、ドラム２１の周面２１ａからワークＷの前部が引き離される。   Specifically, as shown in FIG. 7C, when the front end of the work W reaches the vicinity of the lowest point of the drum 21, the pump (not shown) passes through the first supply passage 238b of the air passage member 238. When the air is supplied from the first supply port 237b of the air switching member 237, the air is supplied to the common flow path 234 via the supply flow path 236 communicating with the first supply port 237b. Therefore, air is discharged from each suction hole 232 of the suction hole group 232A arranged in the width direction communicating with the common flow path 234, and the inner space of the slit groove 231 corresponding to the position of each suction hole group 232A. Since the negative pressure of U is released, the front portion of the work W is separated from the peripheral surface 21a of the drum 21.

また、図７（ｄ）に示すように、ドラム２１の周面２１ａからワークＷの前部が引き離された直後、図示略のポンプによりエア通路部材２３８の第２供給通路２３８ｃを介してエア切替部材２３７の第２供給口２３７ｃから空気を供給すると、該第２供給口２３７ｃに連通している供給流路２３６を介して共通流路２３４に空気が供給される。このため、該共通流路２３４に連通している幅方向に並んだ吸引孔群２３２Ａの各吸引孔２３２から空気が吐出され、該各吸引孔群２３２Ａの位置に対応するスリット溝２３１の内側空間Ｕの負圧が解除されるため、ドラム２１の周面２１ａからワークＷの後部が引き離される。このとき、エア切替部材２３７の第１供給口２３７ｂから空気を供給することを停止している。   Also, as shown in FIG. 7D, immediately after the front portion of the work W is separated from the peripheral surface 21a of the drum 21, air switching is performed by the pump (not shown) via the second supply passage 238c of the air passage member 238. When air is supplied from the second supply port 237c of the member 237, the air is supplied to the common flow path 234 via the supply flow path 236 communicating with the second supply port 237c. Therefore, air is discharged from each suction hole 232 of the suction hole group 232A arranged in the width direction communicating with the common flow path 234, and the inner space of the slit groove 231 corresponding to the position of each suction hole group 232A. Since the negative pressure of U is released, the rear portion of the work W is separated from the peripheral surface 21a of the drum 21. At this time, the supply of air from the first supply port 237b of the air switching member 237 is stopped.

なお、ドラム２１の周面２１ａからワークＷを引き離す際、ドラム２１の軸回転を一時的に停止あるいは減速させると、ドラム２１の周面２１ａからワークＷをより安定的に引き離すことができる。   When the work W is separated from the peripheral surface 21a of the drum 21 and the rotation of the shaft of the drum 21 is temporarily stopped or decelerated, the work W can be more stably separated from the peripheral surface 21a of the drum 21.

その後、ワークＷは、積層テーブル３１に所定枚数積層されると、積層テーブル３１がワークＷの積層体ごと移動したり、あるいはワークＷの積層体が把持されることにより、別の箇所に移送される。   After that, when a predetermined number of the works W are stacked on the stacking table 31, the stacking table 31 moves together with the stacked body of the work W, or is transferred to another place by the stacked body of the work W being gripped. You.

なお、搬送方向の上流側の一組のドラム装置２および積層機構３による所定枚数のワークＷの積層を完了したあと、下流側の一組のドラム装置２および積層機構３によるワークＷの積層を開始するとともに、上流側の一組のドラム装置２および積層機構３により積層された所定枚数のワークＷを次の工程に搬送する。また、下流側のドラム装置２および積層機構３による所定数のワークＷの積層が完了したあと、上流側のドラム装置２および積層機構３によるワークＷの積層を再び開始するとともに、下流側のドラム装置２および積層機構３により積層された所定枚数のワークＷを次の工程に搬送する。   After the lamination of a predetermined number of works W by the pair of drum units 2 and the laminating mechanism 3 on the upstream side in the transport direction is completed, the lamination of the works W by the pair of drum units 2 and the laminating mechanism 3 on the downstream side is completed. At the same time, a predetermined number of works W stacked by the pair of drum devices 2 and the stacking mechanism 3 on the upstream side are transported to the next step. After the lamination of a predetermined number of works W by the downstream drum device 2 and the laminating mechanism 3 is completed, the lamination of the works W by the upstream drum device 2 and the laminating mechanism 3 is started again, and A predetermined number of works W stacked by the apparatus 2 and the stacking mechanism 3 are transported to the next step.

なお、本実施形態では、ドラム２１の最上点でワークＷを貼着して、１８０度の回転位相で回転搬送したあと、ドラム２１の最下点でワークＷを引き離すものとしたが、ドラム２１のその他の箇所でワークＷを貼着したり、あるいは引き離してもよいし、その他の回転位相で回転搬送してもよい。   In the present embodiment, the work W is attached at the uppermost point of the drum 21 and is rotated and conveyed at a rotation phase of 180 degrees, and then the work W is separated at the lowermost point of the drum 21. The work W may be adhered or separated at other places, or may be rotated and conveyed at another rotation phase.

また、上述の機構によりドラム２１の周面２１ａにワークＷを貼着するものとしたが、その他の機構を用いてもよい。   Further, the work W is stuck on the peripheral surface 21a of the drum 21 by the above-described mechanism, but another mechanism may be used.

また、空気吸引によりドラム２１の周面２１ａにワークＷを貼着するものとしたが、その他の機構によりドラム２１の周面２１ａにワークＷを貼着してもよい。   Further, the work W is attached to the peripheral surface 21a of the drum 21 by air suction, but the work W may be attached to the peripheral surface 21a of the drum 21 by another mechanism.

また、ワークＷの前部を回転搬送方向の前半分としたが、ワークＷの前部をその他の長さとしてもよい。ただ、ワークＷを高速かつ安定的に引き離すためには、ワークＷの前部は、ワークＷの前端部から回転搬送方向の全長の１／４〜３／４の長さとするのが好ましく、回転搬送方向の全長の１／３〜２／３の長さとするのがより好ましい。   Further, although the front part of the work W is set to the front half in the rotational conveyance direction, the front part of the work W may be set to another length.
