吸收性物品相關的連續薄片的反折裝置 Reversing device for continuous sheet associated with absorbent articles

本發明，是有關於將用後拋棄紙尿褲等的吸收性物品的連續薄片的寬度方向的各端部反折的反折裝置。 The present invention relates to a folding device for reversing each end portion in the width direction of a continuous sheet of an absorbent article such as a disposable diaper.

習知，在將形成用後拋棄紙尿褲的外構件的連續薄片以其連續方向作為搬運方向進行搬運中，將同薄片的寬度方向的各端部反折，由此，形成用後拋棄紙尿褲的胴周圍的緣部。 It is known that, in the case where the continuous sheet of the outer member for discarding the diaper after the formation is conveyed in the continuous direction as the conveyance direction, the end portions in the width direction of the sheet are folded back, thereby forming the diaper for discarding the diaper after use. Around the edge.

此寬度方向的各端部的反折，是藉由專利文獻1所揭示的反折裝置進行。在此反折裝置中，在寬度方向配置一對反折導引構件，當連續薄片沿著搬運方向通過時，將對應的各端部朝寬度方向的中央側反折。且，各反折導引構件，是設成朝寬度方向可往復移動，對應連續薄片的各端部的位置，朝寬度方向移動。例如，因為蛇行等使連續薄片的各端部整體朝寬度方向的右側靠的情況時，因為連續薄片的反折的折位置的目標位置也朝右側偏離，所以該部分的導引構件會朝右側偏離。 The reflexing of each end portion in the width direction is performed by the folding device disclosed in Patent Document 1. In this folding device, a pair of folding guide members are disposed in the width direction, and when the continuous sheets pass in the conveying direction, the respective end portions are folded toward the center side in the width direction. Further, each of the folding guide members is provided to be reciprocally movable in the width direction, and is moved in the width direction corresponding to the position of each end portion of the continuous sheet. For example, when the entire end portion of the continuous sheet is biased toward the right side in the width direction by meandering or the like, since the target position of the folded position of the reverse sheet of the continuous sheet is also shifted to the right side, the guiding member of the portion is directed to the right side. Deviation.

但是如此將導引構件對應連續薄片的蛇行移動的話，連續薄片，會因為同導引構件而被固定於蛇行位置。如此的話，再下過程也在蛇行位置被搬運，即在下過程連續薄片會在從原本應通過寬度方向的搬運位置位置偏離的狀態下被搬運，其結果，下過程中的寬度方向的加工位置精度惡化等，而可能對於下過程造成不良影響。 However, if the guiding member is moved correspondingly to the meandering of the continuous sheet, the continuous sheet will be fixed to the meandering position by the same guiding member. In this case, the next process is also carried in the meandering position, that is, in the lower process, the continuous sheet is conveyed in a state of being displaced from the position of the conveyance position which should originally pass through the width direction, and as a result, the processing position accuracy in the width direction in the lower process is performed. Deterioration, etc., may have an adverse effect on the next process.

且同導引構件一般因為是鋼製即長大的重量物，其慣性大高速追從性差，所以連續薄片的搬運速度為高速的情況時，對於連續薄片的端部的位置的變化會產生追從遲延，有可能無法正確地在連續薄片的折位置的目標位置反折。 In addition, since the guide member is generally a weight that is grown in steel, the inertia is high in speed and the followability is poor. Therefore, when the conveying speed of the continuous sheet is high, the position of the end of the continuous sheet is changed. Delayed, it may not be possible to correctly reflex at the target position of the folded position of the continuous sheet.

本發明，是有鑑於如上述的習知的問題，其目的是對於下過程中的寬度方向的搬運位置不會產生不良影響，並且連續薄片的各端部的位置即使朝寬度方向變化，仍可將同端部正確地在折位置的目標位置反折。 The present invention has been made in view of the above-described conventional problems, and an object thereof is to prevent adverse effects on the conveyance position in the width direction in the lower process, and the position of each end portion of the continuous sheet can be changed even in the width direction. The same end is correctly folded at the target position of the folding position.

但是在上述的說明中，雖說明「外構件5的外層薄片6的長度方向的各端部6e、6e被反折，從肌膚側覆蓋內層薄片7」，但是本實施例的反折裝置20，是被用在該各端部6e、6e的反折作業。在此，在外層薄片6上，設定有將各端部6e、6e反折用的折位置的目標位置P5a、P5a(第4圖A)。且該紙尿褲1被設計成，在各目標位置P5a、P5a反折的話，各端部6e、6e，會從內層薄片7上將胴周圍彈性構件8B、8B完全地覆蓋，並且進一步也覆蓋吸收性本體3的長度方向的各端部3e、3e。即，如設計在目標位置P5a，各端部6e、6e被反折的話，各端部6e、6e的端緣6ee、6ee的長度方向的位置會位於比胴周圍彈性構件8B、8B更中央側，並且位於比吸收性本體3的長度方向的各端緣部3ee、3ee更中央側。且，由此，朝胴周圍彈性構件8B、8B的使用者的肌膚的接觸狀況被舒緩，就可具有防止肌膚粗糙等的規格，並且假設即使液體從吸收性本體3的各端部3e、3e漏出，仍具有可由外層薄片6阻止該漏出的液體更朝紙尿褲1外的漏出的規格。 However, in the above description, the end portions 6e and 6e in the longitudinal direction of the outer sheet 5 of the outer member 5 are reversely folded, and the inner layer sheet 7 is covered from the skin side. However, the folding device 20 of the present embodiment is described. It is a folding operation used for each of the end portions 6e and 6e. Here, the outer layer sheet 6 is provided with target positions P5a and P5a (fourth drawing A) for folding the respective end portions 6e and 6e. Further, the diaper 1 is designed such that, when the respective target positions P5a, P5a are folded back, the respective end portions 6e, 6e completely cover the elastic members 8B, 8B around the inner layer sheet 7 and further cover the absorption. Each end portion 3e, 3e of the body 3 in the longitudinal direction. That is, if the end portions 6e, 6e are folded at the target position P5a, the positions of the end edges 6ee, 6ee of the respective end portions 6e, 6e in the longitudinal direction are located on the more central side of the elastic members 8B, 8B around the circumference. Further, it is located on the center side of each of the end edge portions 3ee and 3ee in the longitudinal direction of the absorbent body 3. In this way, the contact state of the skin of the user around the elastic members 8B and 8B is soothed, and it is possible to have a specification for preventing skin roughness and the like, and it is assumed that even if the liquid is from the respective end portions 3e, 3e of the absorbent body 3. Leakage still has a specification that the outer sheet 6 prevents the leakage of the liquid from leaking out of the diaper 1.

但是這種反折的規格，不限定於上述。例如，在各目標位置P5a、P5a反折時，各端部6e、6e，雖是從內層薄片7上將胴周圍彈性構件8B、8B完全地覆蓋，但是對於吸收性本體3的長度方向的各端部3e、3e不覆蓋的設計也可以。 However, the specification of such a folding is not limited to the above. For example, in each item When the target positions P5a and P5a are folded back, the respective end portions 6e and 6e completely cover the elastic members 8B and 8B around the inner layer sheet 7, but the end portions 3e in the longitudinal direction of the absorbent body 3 are completely covered. The design that 3e does not cover is also available.

這種紙尿褲1，是由紙尿褲1的生產線被製造。在生產線中，藉由適宜的搬運機構，將紙尿褲1的半成品1a沿著預定的搬運方向由預定的搬運速度搬運。且，在這種搬運中，對於該半成品1a被施加各種零件的接合或熔接、沖壓、沖切等的各種加工，每次依序改變半成品1a的狀態，且最終生成第1圖A的狀態的紙尿褲1。供半成品1a的搬運的搬運機構，是例如使用：在載置面也就是皮帶面具有吸引保持功能的吸引皮帶輸送帶14(第3圖B)、或在上下成對配置的環形皮帶彼此之間形成半成品1a的搬運路的皮帶輸送帶、或是搬運滾子12(第3圖B、第7圖B)等。 This diaper 1 is manufactured by a production line of the diaper 1. In the production line, the semi-finished product 1a of the diaper 1 is conveyed at a predetermined conveyance speed in a predetermined conveyance direction by a suitable conveyance mechanism. Further, in the conveyance, the semi-finished product 1a is subjected to various processes such as joining, welding, punching, punching, and the like of the various parts, and the state of the semi-finished product 1a is sequentially changed each time, and finally the state of FIG. 1A is finally generated. Diapers 1. The transport mechanism for transporting the semi-finished product 1a is, for example, a suction belt conveyor belt 14 (Fig. 3B) having a suction/holding function on the mounting surface, that is, a belt surface, or an endless belt arranged in pairs. A belt conveyor that forms a conveyance path of the semi-finished product 1a or a conveyance roller 12 (Fig. 3B, Fig. 7B).

第3圖A乃至第4圖B，是設在生產線的反折裝置20的說明圖。第3圖A及第4圖A是概略俯視圖，彼此為相同的圖。第3圖B，是顯示第3圖A中的B-B箭頭視圖，在第4圖B中各別顯示第4圖A中的C-C箭頭視圖、D-D箭頭視圖、E-E箭頭視圖、F-F箭頭視圖。 Fig. 3A to Fig. 4B are explanatory views of the folding device 20 provided in the production line. 3A and 4A are schematic plan views, and are the same as each other. Fig. 3B is a view showing a B-B arrow in Fig. 3A, and a C-C arrow view, a D-D arrow view, an E-E arrow view, and an F-F arrow view in Fig. 4A are respectively displayed in Fig. 4B.

如第3圖A所示，朝此反折裝置20被送出的時點的半成品1a，仍是紙尿褲1的製品單位分斷前的搬運方向連續的連續體的狀態。例如，外構件5的外層薄片6，是在搬運方向連續的連續薄片6a的狀態。但是，紙尿褲1的構成零件的幾乎全部，已被組裝在此外層薄片6的連續薄片6a。例如，在外層薄片6的連續薄片6a的肌膚側面也就是上面中，內層薄片7是在連續薄片7a的狀態下被接合，且，在第3圖A乃至第4圖B中雖未圖示，但是這些薄片6a、7a彼此之間，是胴周圍彈性構件8B和貼合皺褶用彈性構件8F、腳周圍彈性構件8L等已***設固定完成。進一步，在內層薄片7的連續薄片7a的肌膚側面也就是上面中，吸收性本體3、3…，是在搬運方向由製品間距間歇地被載置並被接合同上面。 As shown in Fig. 3A, the semi-finished product 1a at the time when the folding device 20 is fed out is still in a state in which the product of the diaper 1 is continuously continuous in the conveyance direction before the product unit is broken. For example, the outer sheet 6 of the outer member 5 is in a state in which the continuous sheet 6a continuous in the conveyance direction. However, the diaper 1 Almost all of the constituent parts have been assembled in the continuous sheet 6a of the outer sheet 6. For example, in the skin side surface of the continuous sheet 6a of the outer layer sheet 6, that is, the inner layer sheet 7 is joined in the state of the continuous sheet 7a, and is not shown in FIG. 3A to FIG. However, between the sheets 6a and 7a, the elastic member 8B around the crucible, the elastic member 8F for fitting the wrinkles, the elastic member 8L around the foot, and the like are inserted and fixed. Further, in the skin side surface of the continuous sheet 7a of the inner layer sheet 7, that is, the absorbent bodies 3, 3, ... are intermittently placed by the product pitch in the conveyance direction and contracted.

且這種狀態的紙尿褲1的半成品1a，是由所謂橫流動的搬運形態被搬運。即，相當於紙尿褲1的寬度方向的方向，是在朝向搬運方向的狀態下被搬運。因此，應被反折的外構件5的外層薄片6的各端部6e、6e，在此半成品1a中，是各別相當於外層薄片6的連續薄片6a的寬度方向的各端部6ae、6ae。 In addition, the semi-finished product 1a of the diaper 1 in this state is conveyed by the so-called horizontal flow conveyance form. In other words, the direction corresponding to the width direction of the diaper 1 is carried in a state of being oriented in the conveyance direction. Therefore, the respective end portions 6e, 6e of the outer sheet 6 of the outer member 5 to be folded back are the end portions 6ae, 6ae in the width direction of the continuous sheet 6a corresponding to the outer sheet 6 in the semi-finished product 1a. .

以下，外層薄片6的連續薄片6a的寬度方向，也稱為CD方向或左右方向。且，外層薄片6的連續薄片6a及內層薄片7的連續薄片7a，也分別只稱為「外層薄片6a」及「內層薄片7a」。進一步，將外層薄片6a及內層薄片7a及各種彈性構件8B、8F、8L…被一體化的外構件5的連續體5a，稱為外裝薄片5a。且，外層薄片6a的端部6ae、6ae，也是外裝薄片5a的各端部5ae、5ae，因此，以下，使用端部5ae、5ae說明。 Hereinafter, the width direction of the continuous sheet 6a of the outer layer sheet 6 is also referred to as a CD direction or a left-right direction. Further, the continuous sheet 6a of the outer sheet 6 and the continuous sheet 7a of the inner sheet 7 are also referred to as "outer sheet 6a" and "inner sheet 7a", respectively. Further, the continuous body 5a of the outer member 5 in which the outer layer sheet 6a and the inner layer sheet 7a and the various elastic members 8B, 8F, 8L are integrated is referred to as an exterior sheet 5a. Further, the end portions 6ae and 6ae of the outer layer sheet 6a are also the end portions 5ae and 5ae of the outer sheet 5a. Therefore, the end portions 5ae and 5ae will be described below.

如第3圖A及第3圖B所示，反折裝置20，是具有：將外裝薄片5a沿著搬運方向搬運的搬運機構、及將外裝薄片5a的CD方向的各端部5ae、5ae反折的反折導引裝置22、及設在比反折導引裝置22更搬運方向的上游側用來調整外裝薄片5a的各端部5ae、5ae的CD方向的位置的寬度方向位置調整裝置40。 As shown in FIG. 3A and FIG. 3B, the folding device 20 is provided with There are a conveyance mechanism that conveys the exterior sheet 5a in the conveyance direction, and a folding guide 22 that reflexes the end portions 5ae and 5ae of the exterior sheet 5a in the CD direction, and is provided at a folding guide. The apparatus 22 is further provided with a width direction position adjusting device 40 for adjusting the position of the end portions 5ae and 5ae of the outer sheet 5a in the CD direction on the upstream side in the conveyance direction.

搬運機構，是例如將搬運滾子12及吸引皮帶輸送帶14組合而構成。即，在對應寬度方向位置調整裝置40的外裝薄片5a的搬運路中使用搬運滾子12，在對應反折導引裝置22的搬運路中使用吸引皮帶輸送帶14。 The transport mechanism is configured by, for example, combining the transport roller 12 and the suction belt conveyor belt 14. In other words, the transport roller 12 is used in the transport path of the exterior sheet 5a corresponding to the width direction position adjusting device 40, and the suction belt conveyor 14 is used in the transport path corresponding to the folding guide device 22.

搬運滾子12，是在搬運方向間歇地被配置複數根。且，藉由作為驅動源的伺服馬達，朝沿著CD方向的旋轉軸周圍驅動旋轉，由此，將被架設於該搬運滾子12的外裝薄片5a朝搬運方向搬運。 The conveyance roller 12 is intermittently arranged in plural in the conveyance direction. In addition, the servo motor as the drive source is driven to rotate around the rotation axis in the CD direction, whereby the exterior sheet 5a placed on the conveyance roller 12 is conveyed in the conveyance direction.

吸引皮帶輸送帶14，是具有環形皮帶15。環形皮帶15，是圈架於在搬運方向的前後隔有間隔配置的一對滾子16、16，且，這些一對滾子16、16之中的至少一方的滾子16，是藉由作為驅動源的伺服馬達被驅動旋轉的驅動滾子16。因此，如第3圖B所示，環形皮帶15，是將長的大致長圓軌道作為周轉軌道朝搬運方向周轉。且，將此周轉軌道中的上側的直線軌道，作為將外裝薄片5a搬運用的搬運路徑使用。且，上述一對的滾子16、16的旋轉軸，因為是各別朝向CD方向，所以環形皮帶15的皮帶面也與CD方向平行。 The belt conveyor belt 14 is attracted to have an endless belt 15. The endless belt 15 is a pair of rollers 16 and 16 which are arranged at intervals in the front-rear direction in the conveyance direction, and at least one of the rollers 16 and 16 of the pair of rollers 16 and 16 is used as The servo motor of the drive source is driven to rotate the drive roller 16. Therefore, as shown in FIG. 3B, the endless belt 15 is formed by rotating a long substantially long circular orbit as a turning track in the conveying direction. Further, the linear track on the upper side of the turning track is used as a conveyance path for transporting the exterior sheet 5a. Further, since the rotation axes of the pair of rollers 16 and 16 are oriented in the CD direction, the belt surface of the endless belt 15 is also parallel to the CD direction.

在此環形皮帶15的皮帶面中，形成有複數吸氣孔 (未圖示)。且，藉由從這些吸氣孔的吸氣，在皮帶面發生吸引力。因此，藉由在該皮帶面，一邊吸引保持外裝薄片5a的下面一邊使環形皮帶15在上述周轉軌道移動，使外裝薄片5a沿著上述的搬運路徑也就是上側的直線軌道從搬運方向的上游側朝下游側被搬運。 In the belt surface of the endless belt 15, a plurality of suction holes are formed (not shown). Moreover, the attraction force occurs on the belt surface by the suction from these suction holes. Therefore, the endless belt 15 is moved on the above-described turning track while sucking and holding the lower surface of the exterior sheet 5a on the belt surface, so that the exterior sheet 5a is conveyed from the conveyance direction along the above-described conveyance path, that is, the upper linear track. The upstream side is transported toward the downstream side.

反折導引裝置22，是對應外裝薄片5a的CD方向的各端部5ae、5ae，具有可將各端部5ae、5ae朝CD方向的中央側反折且設成不能移動的一對反折導引構件24、24。又，這些一對的反折導引構件24、24彼此，是彼此對於CD方向的中心線成為鏡像關係，主要只有此點相異，此以外的點是大致同構造。因此，以下說明一方的反折導引構件24的例，對於另一方的反折導引構件24的說明則省略。 The folding guides 22 are end portions 5ae and 5ae corresponding to the CD direction of the exterior sheet 5a, and have a pair of opposite ends that can be folded in the CD direction toward the center side in the CD direction. The guiding members 24, 24 are folded. Further, the pair of folding guide members 24 and 24 have a mirror image relationship with respect to the center line in the CD direction, and mainly differ only in this point, and the other points are substantially the same structure. Therefore, an example of the folding guide member 24 will be described below, and the description of the other folding guide member 24 will be omitted.

如第4圖B的最上段的F-F箭頭視圖所示，一方的反折導引構件24，是在搬運路徑的CD方向的端部的上方，具有：被配置成對於吸引皮帶輸送帶14的環形皮帶15的皮帶面平行的平板構件24a、及限定外裝薄片5a的實際的折位置的側壁構件24b。平板構件24a，是在與同皮帶面之間隔有預定的間隙，且與該皮帶面相面對地被配置。且，上述的側壁構件24b是被設置在此間隙中的CD方向的端側的部分中。進一步，如第4圖A所示，平板構件24a，是在搬運方向的下游側平面形狀是具有大致三角形狀的部分，該大致三角形狀的部分所具備的複數邊之中位於外裝薄片5a上的一邊24a1，是隨著朝搬運方向的下游側前進朝CD方向的中央側伸出。 As shown in the FF arrow view of the uppermost stage of FIG. 4B, one of the folding guide members 24 has a ring arranged to attract the belt conveyor 14 above the end portion of the conveyance path in the CD direction. The flat member 24a of the belt 15 having the belt surface parallel and the side wall member 24b defining the actual folded position of the outer sheet 5a. The plate member 24a is disposed with a predetermined gap from the belt surface and faces the belt surface. Further, the above-described side wall member 24b is provided in a portion on the end side in the CD direction in this gap. Further, as shown in FIG. 4A, the flat member 24a is a portion having a substantially triangular shape in the downstream side in the conveyance direction, and the plurality of sides of the substantially triangular portion are located on the exterior sheet 5a. One side 24a1 is downstream with the direction of transportation The side advancement projects toward the center side in the CD direction.

因此，依據此構成的話，外裝薄片5a，是在側壁構件24b的位置P24b(相當於曲折位置)被曲折，即將與側壁構件24b的內壁面抵接的位置作為實際的折位置被曲折，並且隨著外裝薄片5a朝搬運方向的下游前進，使比同折位置更CD方向的端側的部分5ae，是藉由進入平板構件24a的下面及皮帶面之間的間隙，使該CD方向的端側的部分5ae也就是一方的端部5ae，是伏在內層薄片7a(第4圖B中未圖示)的肌膚側面也就是上面。且由此，如第4圖A所示該端部5ae是朝CD方向的中央側被反折。 Therefore, according to this configuration, the exterior sheet 5a is bent at the position P24b (corresponding to the meandering position) of the side wall member 24b, that is, the position at which the inner wall surface of the side wall member 24b abuts is bent as an actual folding position, and As the outer sheet 5a advances downstream in the conveyance direction, the portion 5ae on the end side in the CD direction from the same folding position is made to enter the gap between the lower surface of the flat plate member 24a and the belt surface, thereby making the CD direction The end portion 5ae, that is, one end portion 5ae, is the side surface of the skin on the inner layer sheet 7a (not shown in Fig. 4B). Thereby, as shown in Fig. 4A, the end portion 5ae is folded back toward the center side in the CD direction.

寬度方向位置調整裝置40，是將外裝薄片5a的各端部5ae、5ae的CD方向的位置各別獨立調整的裝置。在此，藉由寬度方向位置調整裝置40將外裝薄片5a的各端部5ae、5ae位置調整的理由是因為，一般外裝薄片5a，會發生由搬運張力起因的寬度縮小和蛇行等，由此，各端部5ae、5ae的位置，會從CD方向的正規的搬運位置偏離。因此，藉由該裝置40，將外裝薄片5a的各端部5ae、5ae的位置位置對合在CD方向的正規的搬運位置之後將該外裝薄片5a朝上述的反折導引裝置22送出。 The width direction position adjusting device 40 is a device that independently adjusts the positions of the respective end portions 5ae and 5ae of the outer sheet 5a in the CD direction. Here, the reason why the end portions 5ae and 5ae of the exterior sheet 5a are adjusted by the width direction position adjusting device 40 is because the outer sheet 5a is generally narrowed in width and meandering due to the conveyance tension. Thus, the positions of the respective end portions 5ae and 5ae are deviated from the normal conveyance position in the CD direction. Therefore, the positional position of each end portion 5ae, 5ae of the exterior sheet 5a is aligned with the normal conveyance position in the CD direction by the apparatus 40, and then the exterior sheet 5a is sent out to the above-described folding guide device 22. .

這種寬度方向位置調整裝置40，是對應各端部5ae、5ae各別具有調整外裝薄片5a的CD方向的各端部5ae、5ae的位置用的位置調整機構42、42。又，這些左右的位置調整機構42、42，是彼此對於CD方向的中心線成為鏡像關係，基本的構造是大致相同。因此，以下，只有說明一方的位置調整機構42。 The width direction position adjusting device 40 is provided with position adjusting mechanisms 42 and 42 for adjusting the positions of the end portions 5ae and 5ae of the outer direction sheet 5a in the CD direction, for the respective end portions 5ae and 5ae. Further, these left and right position adjusting mechanisms 42 and 42 have a mirror image relationship with respect to the center line in the CD direction, and the basic structure is substantially the same. Therefore, below, only instructions One position adjustment mechanism 42.

如第4圖A及第4圖B的D-D箭頭視圖所示，位置調整機構42，是具有：將外裝薄片5a的端部5ae從其厚度方向挾入的上下一對的壓輥43a、43b、及將一對的壓輥43a、43b在與外裝薄片5a的上面大致平行的平面內可繞轉移動地導引的導引構件44、及將導引構件44繞支點C44周圍繞轉移動的致動器45、及依據外裝薄片5a的端部5ae中的檢出對象部分的CD方向的位置資訊將致動器45控制的控制部47(第3圖B)。 As shown in the DD arrow diagrams of FIGS. 4A and 4B, the position adjustment mechanism 42 has a pair of upper and lower pressure rollers 43a and 43b that are inserted from the end portion 5ae of the exterior sheet 5a from the thickness direction thereof. And a pair of press rolls 43a, 43b are rotatably guided by the guide member 44 in a plane substantially parallel to the upper surface of the outer sheet 5a, and the guide member 44 is rotated around the fulcrum C44. The actuator 45 and the control unit 47 (Fig. 3B) controlled by the actuator 45 in accordance with the positional information in the CD direction of the detection target portion in the end portion 5ae of the exterior sheet 5a.

又，位置資訊的生成，是在位置調整機構42及反折導引裝置22之間，藉由端部位置檢出感測器50(相當於感測器)，檢出外裝薄片5a的各端部5ae、5ae中的檢出對象部分的CD方向的位置來進行。 Further, the position information is generated between the position adjusting mechanism 42 and the folding guide device 22, and the end position detecting sensor 50 (corresponding to the sensor) detects each of the exterior sheets 5a. The position of the detection target portion of the end portions 5ae and 5ae in the CD direction is performed.

一對壓輥43a、43b，是在將彼此的旋轉軸大致平行地對齊的狀態下被支撐在導引構件44。且，一對壓輥43a、43b之中的一方的滾子43b，是由預定壓力被壓在另一方的滾子43a，由此，這些一對壓輥43a、43b是彼此合作，將外裝薄片5a的端部5ae朝厚度方向挾持入保持。 The pair of pressure rollers 43a and 43b are supported by the guide member 44 in a state in which their rotation axes are aligned substantially in parallel. Further, one of the pair of pressure rollers 43a and 43b is pressed against the other roller 43a by a predetermined pressure, whereby the pair of pressure rollers 43a and 43b cooperate with each other to mount the outer casing. The end portion 5ae of the sheet 5a is held in the thickness direction.

且一對的壓輥43a、43b之中的至少一方的滾子43b是藉由伺服馬達，將外裝薄片5a朝搬運方向的下游側給進的方式驅動旋轉。進一步，由繞轉移動時的一對壓輥43a、43b所產生的外裝薄片5a的給進方向D43(即，一對壓輥43a、43b彼此之間的滾子間隙的位置中的壓輥的旋轉方向D43)，也可藉由導引構件44及致動器45，從外裝薄片5a的搬運方向朝CD方向的端側及中央側的任一傾斜方向變更。 The roller 43b of at least one of the pair of pressure rollers 43a and 43b is driven to rotate so that the outer sheet 5a is fed toward the downstream side in the conveyance direction by the servo motor. Further, the feeding direction D43 of the exterior sheet 5a produced by the pair of pressing rolls 43a, 43b at the time of the revolving movement (that is, the pressing roller in the position of the roller gap between the pair of pressing rolls 43a, 43b) The direction of rotation D43) can also be obtained by the guiding member 44 and the actuator 45. The conveyance direction of the exterior sheet 5a is changed in the inclination direction of the end side and the center side of the CD direction.

因此，在外裝薄片5a的各端部5ae、5ae中，除了與搬運方向平行的移動力以外，也被賦予從壓輥43a、43b朝向CD方向的端側或中央側的移動力，由此，外裝薄片5a的各端部5ae、5ae，是在朝搬運方向的下游被搬運期間，在CD方向的端側或是中央側也各別由預定的各移動量被移動(第3圖A)。以下，如第4圖A所示，對於壓輥43a、43b的給進方向D43的搬運方向的角度稱為給進傾斜角θ。且，此給進傾斜角θ，是在給進方向與搬運方向平行的狀態下為0°，給進方向是隨著朝向CD方向的端側變大，隨著朝向CD方向的中央側變小。即，給進傾斜角θ是正值的情況時朝CD方向的端側給進，負值的情況時朝CD方向的中央側給進。 Therefore, in the end portions 5ae and 5ae of the outer sheet 5a, in addition to the moving force parallel to the conveyance direction, the moving force from the pressure rollers 43a and 43b toward the end side or the center side in the CD direction is also provided. Each of the end portions 5ae and 5ae of the exterior sheet 5a is transported downstream in the transport direction, and is also moved by a predetermined amount of movement in the CD-side end side or the center side (Fig. 3A). . Hereinafter, as shown in FIG. 4A, the angle of the conveyance direction of the press rolls 43a and 43b in the feed direction D43 is referred to as a feed tilt angle θ. Further, the feed inclination angle θ is 0° in a state where the feed direction is parallel to the conveyance direction, and the feed direction becomes larger as the end side toward the CD direction becomes smaller, and becomes smaller toward the center side toward the CD direction. . In other words, when the feed inclination angle θ is a positive value, it is fed toward the end side in the CD direction, and in the case of a negative value, it is fed toward the center side in the CD direction.

該端部5ae的CD方向的移動量，可藉由一對壓輥43a、43b的繞轉移動動作被調整。即，加大朝端側的移動量的情況時，使給進傾斜角θ變大的方式將一對壓輥43a、43b繞轉即可，加大朝相反地中央側的移動量的情況時，使給進傾斜角θ變小的方式將一對的壓輥43a、43b繞轉即可。 The amount of movement of the end portion 5ae in the CD direction can be adjusted by the revolving movement operation of the pair of press rolls 43a and 43b. In other words, when the amount of movement toward the end side is increased, the pair of pressure rollers 43a and 43b may be rotated so as to increase the feed inclination angle θ, and the amount of movement toward the opposite center side may be increased. The pair of press rolls 43a and 43b may be wound in such a manner that the feed inclination angle θ is reduced.

且透過導引構件44將壓輥43a、43b繞轉移動的致動器45，可以例示：伺服馬達、或由伺服馬達驅動的給進螺栓機構和凸輪機構、曲軸機構、或由油壓缸驅動的曲軸機構等。 And the actuator 45 that rotates the pressure rollers 43a, 43b through the guiding member 44 can be exemplified by a servo motor, a feed bolt mechanism and a cam mechanism driven by a servo motor, a crank mechanism, or driven by a hydraulic cylinder. Crankshaft mechanism, etc.

且，移動量(mm)，也可以是例如「在設定成隨著朝向CD方向的端側的值變大的位置座標的情況時，外裝薄片5a的端部5ae被反折之前，將從比壓輥43a、43b更搬運方向的下游側的預定位置中的外裝薄片5a的端緣5aee的位置座標，減算了比同滾子43a、43b更搬運方向的上游側的預定位置中的同端緣5aee的位置座標的值」(參照第3圖A)。因此，在端部5ae朝CD方向的端側被移動的情況時，移動量雖成為正值，但是朝CD方向的中央側被移動的情況時，移動量是成為負值。 In addition, the movement amount (mm) may be, for example, a case where the position of the outer sheet 5a is reversed, when the position of the outer sheet 5a is reversed. The position coordinates of the end edge 5aee of the exterior sheet 5a in the predetermined position on the downstream side in the conveyance direction of the pressure rollers 43a and 43b are reduced to the same as the predetermined position on the upstream side in the conveyance direction of the rollers 43a and 43b. The value of the position coordinate of the edge 5aee" (refer to Fig. 3A). Therefore, when the end portion 5ae is moved toward the end side in the CD direction, the amount of movement becomes a positive value, but when the center side of the CD direction is moved, the amount of movement becomes a negative value.

且這些一對壓輥43a、43b將外裝薄片5a挾持入而賦予CD方向的移動力的CD方向的位置，是設定成比反折導引構件24的側壁構件24b的位置P24b更端側，由此，如後述，成為可確實地將外裝薄片5a的端部5ae朝CD方向的中央側及端側的任一移動，其結果，可以確實地將折位置的目標位置P5a朝CD方向移動直到反折導引構件24的側壁構件24b的位置P24b為止。 The position in the CD direction in which the pair of pressure rollers 43a and 43b hold the outer sheet 5a and the movement force in the CD direction is set to be closer to the end than the position P24b of the side wall member 24b of the folding guide member 24. Therefore, as will be described later, the end portion 5ae of the exterior sheet 5a can be reliably moved to the center side and the end side in the CD direction, and as a result, the target position P5a of the folding position can be surely moved in the CD direction. Until the position P24b of the side wall member 24b of the folding guide member 24 is reversed.

控制部47，是適宜的電腦和PLC(可設計程式的邏輯控制器)等，具有處理器及記憶體。且，處理器是藉由將被容納在記憶體的控制程式讀出並實行，使控制部47控制致動器45。 The control unit 47 is a suitable computer and PLC (a logic controller that can design a program), and has a processor and a memory. Further, the processor reads and executes the control program housed in the memory, and causes the control unit 47 to control the actuator 45.

在此，上述的控制程式，在記憶體中，隨著上述的端部5ae的位置資訊，使外裝薄片5a的折位置的目標位置P5a，對齊反折導引裝置22的反折導引構件24的側壁構件24b的位置P24b(參照第4圖B的F-F箭頭視圖)，將致動器45控制的程式，是被容納於每一端部5ae、5ae。因此，在此控制程式的實行下，外裝薄片5a上的折位置的各目標位置P5a、P5a，是與各反折導引構件24的側壁構件24b的位置P24b、P24b一致的方式使各致動器45、45被控制。 Here, in the above control program, in the memory, the target position P5a of the folded position of the exterior sheet 5a is aligned with the folding guide member of the folding guide 22 in accordance with the position information of the end portion 5ae described above. Position P24b of the side wall member 24b of 24 (refer to the FF arrow view of FIG. 4B), The program controlled by the actuator 45 is housed at each end portion 5ae, 5ae. Therefore, in the execution of this control program, the respective target positions P5a, P5a of the folding position on the exterior sheet 5a are aligned with the positions P24b, P24b of the side wall members 24b of the respective folding guide members 24. The actuators 45, 45 are controlled.

例如，外裝薄片5a的一方的端部5ae是由蛇行起因等使CD方向的正規位置更朝端側移動的情況時，外裝薄片5a上的折位置的目標位置P5a，是比反折導引構件24的側壁構件24b的位置P24b更朝CD方向的端側移動。如此的話，會將比折位置的目標位置P5a更CD方向的中央側的位置作為實際的折位置被反折，雖會成為反折不良，但是在此情況下，控制部47，是依據從端部位置檢出感測器50被送出的端部5ae的檢出對象部分的位置資訊，減小上述一對壓輥43a、43b的給進方向D43的給進傾斜角θ地減小移動量，由此，將外裝薄片5a的端部5ae朝CD方向的中央側移動。其結果，外裝薄片5a上的折位置的目標位置P5a，是朝CD方向的中央側移動並被對齊在反折導引構件24的側壁構件24b，使端部5ae在同目標位置P5a被反折。 For example, when one end portion 5ae of the exterior sheet 5a is moved to the end side in the CD direction by a meandering or the like, the target position P5a of the folding position on the exterior sheet 5a is a ratio of the reverse guide. The position P24b of the side wall member 24b of the lead member 24 is further moved toward the end side in the CD direction. In this case, the position on the center side in the CD direction at the target position P5a of the folding position is reversed as the actual folding position, and the folding position is defective. However, in this case, the control unit 47 is based on the slave end. The positional information of the detection target portion of the end portion 5ae to which the sensor position detecting unit 50 is sent is reduced, and the amount of movement is reduced by decreasing the feed inclination angle θ of the feeding direction D43 of the pair of pressure rollers 43a and 43b. Thereby, the end portion 5ae of the exterior sheet 5a is moved toward the center side in the CD direction. As a result, the target position P5a of the folding position on the exterior sheet 5a is moved toward the center side in the CD direction and is aligned with the side wall member 24b of the folding guide member 24, so that the end portion 5ae is reversed at the same target position P5a. fold.

另一方面，外裝薄片5a的一方的端部5ae是由寬度縮小起因等而比CD方向的正規位置更朝中央側移動的情況時，外裝薄片5a上的折位置的目標位置P5a，是比反折導引構件24的側壁構件24b的位置P24b更朝CD方向的中央側移動。如此的話，會將比折位置的目標位置P5a更 CD方向的端側的位置作為實際的折位置被反折，雖會成為反折不良，但是在此情況下，控制部47，可依據位置資訊加大給進傾斜角θ而加大移動量，由此，將外裝薄片5a的端部5ae朝CD方向的端側移動。其結果，外裝薄片5a上的折位置的目標位置P5a，會朝CD方向的端側移動並被對齊在反折導引構件24的側壁構件24b，使端部5ae在同目標位置P5a被反折。 On the other hand, when one end portion 5ae of the exterior sheet 5a is moved toward the center side from the normal position in the CD direction due to the width reduction or the like, the target position P5a of the folding position on the exterior sheet 5a is The position P24b of the side wall member 24b of the folding guide member 24 is moved toward the center side in the CD direction. In this case, the target position P5a of the folding position will be more The position on the end side in the CD direction is reversed as the actual folding position, and the folding position is defective. However, in this case, the control unit 47 can increase the feeding inclination angle θ according to the position information and increase the amount of movement. Thereby, the end portion 5ae of the exterior sheet 5a is moved toward the end side in the CD direction. As a result, the target position P5a of the folded position on the exterior sheet 5a moves toward the end side in the CD direction and is aligned with the side wall member 24b of the folding guide member 24, so that the end portion 5ae is reversed at the same target position P5a. fold.

又，上述控制程式的其中一例，可舉例，例如計算：位置資訊所顯示的檢出對象部分的CD方向的位置、及該檢出對象部分是原本應位置的CD方向的正規位置的差，依據該差將給進傾斜角θ的變更量△θ算出，使給進傾斜角成為θ+△θ的方式控制致動器45的程式等。 Further, as an example of the above-described control program, for example, the difference between the position in the CD direction of the detection target portion displayed by the position information and the normal position in the CD direction of the original position should be calculated. This difference is calculated by calculating the amount of change Δθ of the inclination angle θ, and controlling the program of the actuator 45 such that the feed inclination angle becomes θ + Δθ.

且這種控制，是對於左右的各位置調整機構42、42各被獨立進行，由此，上述的移動量的變更，是在每一端部5ae、5ae各獨立進行。 In this control, each of the left and right position adjustment mechanisms 42 and 42 is independently performed, and thus the above-described movement amount is changed independently at each of the end portions 5ae and 5ae.

端部位置檢出感測器50，是如第3圖A及第3圖B所示，具有：對應外裝薄片5a的各端部5ae、5ae被設置，將外裝薄片5a的對應的各端部5ae、5ae各別攝像並生成平面畫像資料的一對照相機52、52；及對應各照相機52、52各別被配置，且被配置於由對應的各照相機52、52從上下挾持的位置的一對照明構件54、54、及依據從各照相機52、52被發訊的各平面畫像資料生成各端部5ae、5ae的檢出對象部分的位置資訊輸出的畫像處理部56。 As shown in FIG. 3 and FIG. 3B, the end position detecting sensor 50 has the respective end portions 5ae and 5ae corresponding to the exterior sheet 5a, and the corresponding outer sheets 5a are provided. The end portions 5ae and 5ae respectively capture a pair of cameras 52 and 52 that generate planar image data; and the respective cameras 52 and 52 are disposed separately, and are disposed at positions held by the corresponding cameras 52 and 52 from above and below. The pair of illumination members 54 and 54 and the image processing unit 56 that outputs the position information of the detection target portions of the respective end portions 5ae and 5ae based on the respective planar image data transmitted from the cameras 52 and 52.

各照相機52、52，是例如CCD(電荷結合元件)照相機。且，各照相機52、52，是各別與外裝薄片5a的上面中的負責的各端部5ae、5ae相面對配置，由此，將通過攝像位置P52的外裝薄片5a的上面的各端部5ae、5ae的檢出對象部分攝像，生成檢出對象部分的平面畫像的資料(以下稱為平面畫像資料)。攝像位置P52，是位於壓輥43a、43b及反折導引構件24之間的位置。因此，各照相機52，是攝像：藉由壓輥43a、43b將CD方向的位置調整後的端部5ae、及藉由反折導引構件24被反折之前的端部5ae。 Each of the cameras 52, 52 is, for example, a CCD (Charge Coupled Device) camera. Further, each of the cameras 52 and 52 is disposed so as to face each of the respective end portions 5ae and 5ae of the upper surface of the exterior sheet 5a, whereby each of the upper surfaces of the exterior sheets 5a passing through the imaging position P52 is placed. The detection target portion of the end portions 5ae and 5ae is imaged, and data of a planar image of the detection target portion (hereinafter referred to as planar image data) is generated. The imaging position P52 is a position between the pressure rollers 43a and 43b and the folding guide member 24. Therefore, each of the cameras 52 is an end portion 5ae whose position in the CD direction is adjusted by the pressure rollers 43a and 43b, and an end portion 5ae before the folding guide member 24 is folded back.

且攝像動作，是由預先被設定的適宜的控制周期在每一照相機52、52進行，每次各平面畫像資料的生成，就將各平面畫像資料朝畫像處理部56發訊。如此的話，在畫像處理部56中，每次各平面畫像資料的收訊，依據各平面畫像資料，將顯示外裝薄片5a的各端部5ae、5ae的檢出對象部分的CD方向的位置的位置資訊算出，朝寬度方向位置調整裝置40的控制部47發訊，在同控制部47中，將前述的各致動器45、45的控制由上述的控制周期進行。 The imaging operation is performed on each of the cameras 52 and 52 by an appropriate control cycle set in advance, and each of the planar image data is generated for each of the planar image data. In this way, in the image processing unit 56, the position of the detection target portion of each end portion 5ae, 5ae of the exterior sheet 5a in the CD direction is displayed in accordance with each plane image data for each reception of the plane image data. The position information calculation is performed by the control unit 47 of the width direction position adjusting device 40, and the control unit 47 controls the above-described respective actuators 45 and 45 by the above-described control cycle.

各照明構件54、54，是例如白色LED燈和螢光燈等的適宜的燈，其光源的種類，可對應當時的攝像狀況適宜地選用。且，如上述，各照明構件54的配置位置，是設定於可由與對應的照相機52將外裝薄片5a從同薄片5a的厚度方向挾持的位置。由此，各照相機52，是藉由使外裝薄片5a受光朝厚度方向透過的透過光進行攝像。 Each of the illumination members 54 and 54 is a suitable lamp such as a white LED lamp or a fluorescent lamp, and the type of the light source can be appropriately selected in accordance with the imaging condition at that time. Further, as described above, the arrangement position of each of the illumination members 54 is set at a position that can be held by the corresponding camera 52 from the thickness direction of the same sheet 5a. Thus, each camera 52 is made by The sheet 5a is imaged by transmitted light that is transmitted through the light in the thickness direction.

畫像處理部56，是將適宜的電腦作為本體，具有處理器及記憶體。且處理器是藉由將預先被容納在記憶體的二值化處理程式讀出並實行，對於從各照相機52、52被送出的各平面畫像資料進行二值化處理，各別生成各端部5ae、5ae的檢出對象部分的位置資訊。又，以下說明的位置資訊的生成的內容是各端部5ae、5ae因為也相同，所以只有說明一方的端部5ae。 The image processing unit 56 has a suitable computer as a main body and has a processor and a memory. The processor reads and executes the binarization processing program stored in advance in the memory, and binarizes each plane image data sent from each of the cameras 52 and 52, and generates each end portion separately. The position information of the detected object part of 5ae and 5ae. In addition, since the content of the position information described below is the same for each of the end portions 5ae and 5ae, only one end portion 5ae will be described.

第5圖是檢出對象部分的說明圖，在同第5圖中，擴大顯示被反折之前的外層薄片5a的端部5ae。 Fig. 5 is an explanatory view of the portion to be detected, and in the same manner as Fig. 5, the end portion 5ae of the outer layer sheet 5a before being folded back is enlarged.

檢出對象部分，雖可舉例例如胴周圍彈性構件8B和內層薄片7a的CD方向的端緣7aee、外層薄片6a的端緣6aee(外裝薄片5a的端緣5aee)等，但是在本實施例中，設定於胴周圍彈性構件8B、8B之中位於最CD方向的端側的胴周圍彈性構件8B(正確是在外裝薄片5a中胴周圍彈性構件8B被配置的部分5a8B)。這是因為只有比此胴周圍彈性構件8B的位置更2~3mmCD方向的端側的位置，是被設計在外裝薄片5a的折位置的目標位置P5a。且，如此由胴周圍彈性構件8B的位置基準，將比同位置更只有2~3mmCD方向的端側的位置設計在折位置的目標位置P5a的理由，是因為假設胴周圍彈性構件8B是與折位置的目標位置P5a一致的話，形成紙尿褲1的胴周圍開口部1hB的緣部5e，會由胴周圍彈性構件8B的作用朝使用者的肌膚嚙入等而有可能使肌膚粗糙。 The detection target portion may be, for example, an end edge 7aee in the CD direction of the surrounding elastic member 8B and the inner layer sheet 7a, an end edge 6aee of the outer layer sheet 6a (an end edge 5aee of the exterior sheet 5a), and the like. In the example, the peripheral elastic member 8B located on the end side in the most CD direction among the elastic members 8B and 8B around the crucible is set to the portion 5a8B in which the elastic member 8B is disposed around the outer sheet 5a. This is because only the position on the end side in the CD direction of 2 to 3 mm in the CD member than the position of the elastic member 8B around the crucible is the target position P5a designed at the folding position of the exterior sheet 5a. Further, the reason why the position of the end side of the ~2 to 3 mm CD direction is designed to be at the target position P5a of the folding position by the positional reference of the surrounding elastic member 8B is because the elastic member 8B around the cymbal is assumed to be folded. When the target position P5a of the position is the same, the edge portion 5e of the opening portion 1hB around the crotch of the diaper 1 is formed, and the skin may be roughened by the action of the surrounding elastic member 8B.

且如本實施例在端部位置檢出感測器50使用照相機52的話，如上述將胴周圍彈性構件8B作為檢出對象部分的方式，外裝薄片5a的端緣5aee(即外層薄片6a的端緣6aee)以外的部分也可作為檢出對象部分，就可提高檢出對象部分的選擇自由度。 In the present embodiment, when the end position detecting sensor 50 uses the camera 52, the end edge 5aee of the outer sheet 5a (i.e., the outer sheet 6a) is used as the detecting target portion as described above. The portion other than the edge 6aee) can also be used as the detection target portion, and the degree of freedom in selection of the detection target portion can be improved.

在第6圖中，顯示藉由照相機52被攝像的平面畫像的想像圖。又，在同第6圖中，為了理解容易的目的，折位置的目標位置P5a也由二點鎖線圖示，但是在實際的平面畫像中這種線不會被攝像。 In Fig. 6, an imaginary diagram of a planar image captured by the camera 52 is displayed. Further, in the same drawing as Fig. 6, for the purpose of easy understanding, the target position P5a of the folding position is also illustrated by the two-point lock line, but such an line is not imaged in the actual plane image.

平面畫像，是例如將CD方向作為X方向，將搬運方向作為Y方向進行攝像，且，平面畫像，是包含作為檢出對象部分的胴周圍彈性構件8B的方式被攝像。 In the planar image, for example, the CD direction is referred to as the X direction, and the conveyance direction is captured as the Y direction, and the planar image is imaged so as to include the surrounding elastic member 8B as the detection target portion.

這種平面畫像，是在X方向及Y方向的雙方向由依據各別預定的解像度的預定間距呈格子狀並列多數畫素的集合體。換言之，平面畫像，是使在X方向由以預定間距並列成一直線的複數畫素所構成的畫素列，在Y方向由預定間距並列複數列所構成。且，平面畫像資料，是對應各畫素各別具有顏色資訊。例如，平面畫像資料是灰階的情況時，在每一畫素的色資訊只有明度。且，在該情況中，在外裝薄片5a中對應透光性較高的領域的各畫素因為變明亮，所以該畫素的明度會成為較高的值，但是另一方面，對應透光性較低的領域的各畫素因為變暗，所以該畫素的明度成為較低的值。 Such a planar image is an aggregate in which a plurality of pixels are arranged in a lattice shape at predetermined intervals in accordance with respective predetermined resolutions in both directions of the X direction and the Y direction. In other words, the planar image is a pixel sequence composed of a plurality of pixels arranged in a line at a predetermined pitch in the X direction, and is formed by juxtaposing a plurality of columns at a predetermined pitch in the Y direction. Moreover, the planar image data has color information corresponding to each pixel. For example, when the planar image data is grayscale, the color information of each pixel has only brightness. In this case, in the exterior sheet 5a, since the pixels corresponding to the region having high light transmittance are brightened, the brightness of the pixel becomes a high value, but on the other hand, the light transmittance is corresponding. Since the pixels of the lower field become darker, the brightness of the pixel becomes a lower value.

在此，在外裝薄片5a中胴周圍彈性構件8B被配置的部分5a8B(以下稱為胴周圍彈性構件配置部分5a8B)，是透光性較低的部分。因此，畫像處理部56，是藉由矚目於明度是在預定的門檻值以下的畫素，在第6圖的平面畫像上，將胴周圍彈性構件配置部分5a8B、5a8B被攝像的領域A5a8B、A5a8B的畫素抽出。且，在平面畫像的各畫素中被賦予XY座標，這些XY座標是被記錄於記憶體。因此，畫像處理部56，是藉由從記憶體取得被抽出的畫素的XY座標，並且從被取得的XY座標之中選擇X座標最大值者，就可以取得對應CD方向的端側的胴周圍彈性構件配置部分5a8B的X座標。進一步，在記憶體中，被記錄對應X座標、及CD方向的位置的對應資料。因此，從這種對應資料，取得對應被抽出的畫素的XY座標的CD方向的位置，將此作為胴周圍彈性構件8B的CD方向的位置資訊朝寬度方向位置調整裝置40的控制部47發訊。且，在同控制部47中，如前述，依據此位置資訊控制致動器45，由此，外裝薄片5a上的折位置的目標位置P5a，是被調整成對齊在反折導引構件24的側壁構件24b的位置P24b。 Here, the elastic member 8B around the crucible is disposed in the exterior sheet 5a. The portion 5a8B (hereinafter referred to as the periorbital elastic member arranging portion 5a8B) is a portion having low light transmittance. Therefore, the image processing unit 56 captures the fields A5a8B and A5a8B in which the surrounding elastic member placement portions 5a8B and 5a8B are imaged on the plane image of Fig. 6 by focusing on the pixels whose brightness is equal to or lower than the predetermined threshold value. The pixels are drawn out. Further, XY coordinates are given to each pixel of the planar image, and these XY coordinates are recorded in the memory. Therefore, the image processing unit 56 obtains the XY coordinates of the extracted pixels from the memory, and selects the maximum value of the X coordinates from among the acquired XY coordinates, so that the end side corresponding to the CD direction can be obtained. The X coordinate of the surrounding elastic member arranging portion 5a8B. Further, in the memory, corresponding data corresponding to the X coordinate and the position in the CD direction are recorded. Therefore, from the corresponding data, the position in the CD direction corresponding to the XY coordinates of the extracted pixel is obtained, and the position information in the CD direction of the surrounding elastic member 8B is sent to the control unit 47 of the width direction position adjusting device 40.

Further, in the same control unit 47, as described above, the actuator 45 is controlled based on the position information, whereby the target position P5a of the folding position on the exterior sheet 5a is adjusted to be aligned with the folding guide member 24. Position P24b of the side wall member 24b.

但是將上述的寬度方向位置調整裝置40及端部位置檢出感測器50，適用在生產線的別的裝置也可以。例如，適用在被配置於上述的反折裝置20的搬運方向的上游的90°旋轉滾筒裝置60(相當於載置裝置)也可以。在此90°旋轉滾筒裝置60中，將吸收性本體3、3…載置固定在朝搬運方向被搬運的外裝薄片5a的肌膚側面也就是上面。因此，將上述的寬度方向位置調整裝置40及端部位置檢出感測器50適用在該裝置60的話，假設即使外裝薄片5a蛇行的情況，可以由較高的位置對合精度將吸收性本體3載置固定在被設定於外裝薄片5a上的吸收性本體3應位置的CD方向的正規的位置。以下，詳細說明。 However, the above-described width direction position adjusting device 40 and end position detecting sensor 50 may be applied to another device of the production line. For example, it may be applied to a 90° rotating drum device 60 (corresponding to a placing device) disposed upstream of the conveying direction of the folding device 20 described above. In the 90° rotating drum device 60, the absorbent bodies 3, 3, ... are placed and fixed on the side surface of the skin of the exterior sheet 5a conveyed in the conveying direction. Therefore, when the above-described width direction position adjusting device 40 and end position detecting sensor 50 are applied to the device 60, it is assumed that even if the outer sheet 5a is meandered, the absorption accuracy can be improved by the higher positional matching accuracy. The main body 3 is placed at a regular position in the CD direction fixed to the position of the absorbent body 3 set on the exterior sheet 5a. The details will be described below.

第7圖A及第7圖B，是其說明圖。在第7圖A中顯示概略俯視圖，在第7圖B中，顯示第7圖A中的B-B箭頭視圖。 Fig. 7 and Fig. 7B are explanatory diagrams. A schematic plan view is shown in Fig. 7A, and a B-B arrow view in Fig. 7A is shown in Fig. 7B.

如第7圖B所示，90°旋轉滾筒裝置60，是具有：朝沿著CD方向的旋轉軸周圍驅動旋轉的旋轉滾筒62、及由製品間距被設在旋轉滾筒62的外周面的複數保持墊片64、64…、及設在旋轉滾筒62的周轉方向的預定位置的裁刀滾子68。 As shown in Fig. 7B, the 90° rotating drum unit 60 has a rotary drum 62 that is driven to rotate around a rotating shaft in the CD direction, and a plurality of holdings that are provided on the outer peripheral surface of the rotating drum 62 by the product pitch. The spacers 64, 64, ... and the cutter roller 68 provided at a predetermined position in the circumferential direction of the rotary drum 62.

在此，朝此90°旋轉滾筒裝置60被送出的時點的吸收性本體3，是在未呈單票狀被分斷的長度方向連續的連續體3a。另一方面，在旋轉滾筒62的周轉方向的預定位置中，被設定有將吸收性本體3的連續體3a收取的收取位置Pin。因此，通過此收取位置Pin的保持墊片64，是將吸收性本體3的連續體3a的下游端部3ae吸附保持並收取，並且同保持墊片64收取完成時，裁刀滾子68是在保持墊片64的上游端緣部64e將吸收性本體3的連續體3a分斷，由此在保持墊片64上生成單票狀的吸收性本體3。 Here, the absorbent main body 3 at the time when the 90° rotating drum device 60 is fed out is a continuous body 3a that is continuous in the longitudinal direction that is not divided into a single ticket shape. On the other hand, in a predetermined position in the circumferential direction of the rotary drum 62, a take-up position Pin for collecting the continuous body 3a of the absorbent body 3 is set. Therefore, by the holding pad 64 of the pickup position Pin, the downstream end portion 3ae of the continuous body 3a of the absorbent body 3 is suction-held and collected, and when the holding of the holding spacer 64 is completed, the cutter roller 68 is The upstream end edge portion 64e of the holding spacer 64 breaks the continuous body 3a of the absorbent body 3, whereby the single-shaped absorbent body 3 is formed on the holding spacer 64.

且在旋轉滾筒62的周轉方向的預定位置中，被設定有保持墊片64是將保持的吸收性本體3朝外裝薄片5a拉_ 引傳送的拉引橫跨位置Pout。即，在此拉引橫跨位置Pout中，外裝薄片5a是在連續薄片的狀態下沿著搬運方向被搬運。因此，保持墊片64通過此拉引橫跨位置Pout時，保持墊片64的吸收性本體3是藉由朝外裝薄片5a被拉引接合等而被接合在外裝薄片5a，由此，使吸收性本體3被載置固定在外裝薄片5a上。 And in a predetermined position in the circumferential direction of the rotary drum 62, the holding spacer 64 is set to pull the held absorbent body 3 toward the outer sheet 5a_ The pull of the lead is transmitted across the position Pout. In other words, in the drawing traverse position Pout, the exterior sheet 5a is conveyed in the conveyance direction in the state of the continuous sheet. Therefore, when the holding spacer 64 is pulled across the position Pout, the absorbent body 3 of the holding spacer 64 is joined to the exterior sheet 5a by being pulled or joined to the exterior sheet 5a, thereby The absorbent body 3 is placed and fixed on the exterior sheet 5a.

又，此時，外裝薄片5a，是以橫流動的搬運形態被搬運。因此，隨此吸收性本體3也必須從成為橫流動的搬運形態朝外裝薄片5a拉引傳送。即，有需要將吸收性本體3的長度方向的方向，從搬運方向朝CD方向變更，但是對於此變更，在從收取位置Pin至拉引橫跨位置Pout為止之間使保持墊片64移動期間，保持墊片64是藉由保持墊片64的平面中心自轉來進行。 Moreover, at this time, the exterior sheet 5a is conveyed in the conveyance form of a horizontal flow. Therefore, the absorbent body 3 must also be pulled and conveyed toward the exterior sheet 5a from the conveyance form which is a horizontal flow. In other words, it is necessary to change the direction of the longitudinal direction of the absorbent body 3 from the conveyance direction to the CD direction. However, in this change, the holding spacer 64 is moved between the pickup position Pin and the pull-up position Pout. The retaining spacer 64 is performed by maintaining the center of the plane of the spacer 64 to rotate.

且在吸收性本體3的保持中，保持墊片64可將吸收性本體3確實吸附保持，其CD方向的位置精度可有效被維持。因此，在90°旋轉滾筒裝置60中，在保持墊片64的各端緣部64e、64e(相當於各基準部位)，使吸收性本體3的各端緣部3ee、3ee(相當於各特定部位)一致的方式一邊將吸收性本體3的CD方向的位置確實地限制，一邊使保持墊片64將吸收性本體3載置在外裝薄片5a上。因此，90°旋轉滾筒裝置60所起因的吸收性本體3的CD方向的位置對合不良(位置偏離)就大致不會發生，同位置對合不良，主要是起因於外裝薄片5a的蛇行和寬度縮小。 And in the holding of the absorbent body 3, the holding spacer 64 can surely adsorb and hold the absorbent body 3, and the positional accuracy in the CD direction can be effectively maintained. Therefore, in the 90° rotating drum device 60, each end edge portion 3e, 3ee (corresponding to each reference portion) of the holding spacer 64 is provided with each end edge portion 3ee and 3ee of the absorbent body 3 (corresponding to each specific When the position of the absorbent body 3 in the CD direction is surely restricted, the holding spacer 64 is placed on the exterior sheet 5a by the holding spacer 64. Therefore, the positional misalignment (positional deviation) of the absorbent body 3 in the CD direction caused by the 90° rotating drum device 60 does not substantially occur, and the same position is poorly coupled, mainly due to the meandering of the outer sheet 5a. The width is reduced.

對於這種90°旋轉滾筒裝置60，寬度方向位置調整裝置40(相當於第2寬度方向位置調整裝置)，是被設於比外裝薄片5a的搬運路徑中的上述拉引橫跨位置Pout更上游側的位置。且，此寬度方向位置調整裝置40，也與前述的反折裝置20的寬度方向位置調整裝置40同樣地，將調整外裝薄片5a的各端部5ae、5ae的CD方向的位置的位置調整機構42、42對應各端部5ae、5ae地形成，且，對應各位置調整機構42、42形成使各端部5ae、5ae的位置資訊輸出的端部位置檢出感測器50(相當於第2感測器)。又，以下，雖只有說明CD方向的一方的位置調整機構42及照相機52，對於另一方的位置調整機構42及照相機52也同樣。 In the 90° rotating drum device 60, the width direction position adjusting device 40 (corresponding to the second width direction position adjusting device) is provided at the above-described drawing traverse position Pout in the conveyance path of the exterior sheet 5a. The position on the upstream side. In the same manner as the width direction position adjustment device 40 of the folding device 20, the position adjustment mechanism for adjusting the position of the end portions 5ae and 5ae of the exterior sheet 5a in the CD direction is also used. 42 and 42 are formed corresponding to the respective end portions 5ae and 5ae, and the end position detecting sensor 50 for outputting the position information of each of the end portions 5ae and 5ae is formed corresponding to each of the position adjusting mechanisms 42 and 42 (corresponding to the second Sensor). In the following description, only one of the position adjustment mechanism 42 and the camera 52 in the CD direction will be described, and the same applies to the other position adjustment mechanism 42 and the camera 52.

端部位置檢出感測器50的照相機52，是作為外裝薄片5a上的第2檢出對象部分，將從例如CD方向的端至第三條的貼合皺褶用彈性構件8F(參照第5圖)被配置的部分5a8F由預定的控制周期攝像，每次攝像，就生成平面畫像資料朝畫像處理部56發訊。在畫像處理部56中，每次平面畫像資料的收訊，就將平面畫像資料二值化處理並生成貼合皺褶用彈性構件8F的CD方向的位置資訊，朝寬度方向位置調整裝置40的控制部47發訊。 The camera 52 of the end position detecting sensor 50 is a second detecting target portion on the exterior sheet 5a, and the elastic member 8F for pleating the wrinkles from the end in the CD direction to the third strip (refer to Fig. 5) The arranged portion 5a8F is imaged by a predetermined control cycle, and each time the image is captured, the plane image data is generated and sent to the image processing unit 56. In the image processing unit 56, the planar image data is binarized and the positional information in the CD direction of the corrugated elastic member 8F is formed, and the positional adjustment device 40 is oriented in the width direction. The control unit 47 sends a message.

如此的話，在寬度方向位置調整裝置40的控制部47中，每次位置資訊的收訊，就計算：收訊到的位置資訊所顯示的CD方向的位置、及從CD方向的端至第三條的貼合皺褶用彈性構件8F原本應位置的CD方向的正規位置的差，依據該差，將壓輥43a、43b的給進傾斜角θ的變更量△θ算出，使給進傾斜角成為θ+△θ的方式控制致動器45。且，由此，外裝薄片5a上吸收性本體3的端緣部3ee應位置的位置(相當於載置用目標位置)，是使對齊在拉引橫跨位置Pout中的保持墊片64的端緣部64e的位置的方式，變更外裝薄片5a的端部5ae的CD方向的移動量。 In this case, in the control unit 47 of the width direction position adjusting device 40, each time the position information is received, the position in the CD direction displayed by the received position information and the end from the CD direction to the third are calculated. The regular position of the strip in the CD direction of the elastic member 8F for the wrinkle In the difference, the amount of change Δθ of the feed inclination angle θ of the pressure rollers 43a and 43b is calculated, and the actuator 45 is controlled so that the feed inclination angle becomes θ + Δθ. Further, the position of the end edge portion 3ee of the absorbent body 3 on the exterior sheet 5a (corresponding to the target position for placement) is such that the holding spacer 64 is aligned in the pull-up position Pout. The amount of movement of the end portion 5ae of the exterior sheet 5a in the CD direction is changed in such a manner as to position the edge portion 64e.

又，在上述的例中，作為外裝薄片5a上的第2檢出對象部分，雖例示了從CD方向的端至第三條的貼合皺褶用彈性構件8F(第5圖)被配置的部分5a8F，但是皆不限定於此，將外裝薄片5a上的別的部位作為第2檢出對象部分也可以。但是，從位置對合精度提高的觀點，端部位置檢出感測器50可檢出的部分之中，將最接近吸收性本體3的端緣部3ee(第5圖)應位置的部位的構件作為第2檢出對象部分最佳，在本實施例中，該最接近部分，因為是從CD方向的端至第三條的貼合皺褶用彈性構件8F，所以將其配置部分5a8F作為第2檢出對象部分。 Moreover, in the above-described example, the second detection target portion on the exterior sheet 5a is exemplified as the elastic member 8F (Fig. 5) for bonding the wrinkles from the end in the CD direction to the third strip. The portion 5a8F is not limited thereto, and the other portion on the exterior sheet 5a may be the second detection target portion. However, from the viewpoint of improving the positional matching accuracy, among the portions detectable by the end position detecting sensor 50, the portion closest to the end edge portion 3ee (Fig. 5) of the absorbent body 3 should be located. The member is preferably the second detection target portion. In the present embodiment, since the closest portion is the elastic member 8F for bonding the wrinkles from the end in the CD direction to the third strip, the arrangement portion 5a8F is used as the member. The second detection target part.

且如第7圖A所示，位置調整機構42的一對壓輥43a、43b將外裝薄片5a挾入並賦予CD方向的移動力的CD方向的位置，是設定於比拉引橫跨位置Pout中的保持墊片64的CD方向的端緣部64e的位置P64e更CD方向的端側。且，由此，成為可確實地將外裝薄片5a的端部5ae朝CD方向的中央側及端側的任一移動，其結果，可以確實地將外裝薄片5a上吸收性本體3的端緣部3ee應位置的部位，直到上述保持墊片64的端緣部64e的位置 P64e為止朝CD方向移動。 As shown in Fig. 7A, the position of the pair of press rolls 43a and 43b of the position adjusting mechanism 42 which is inserted into the outer sheet 5a and imparts a moving force in the CD direction to the position in the CD direction is set to the ratio of the pull-to-pull position. The position P64e of the end edge portion 64e in the CD direction of the holding spacer 64 in the Pout is more the end side in the CD direction. In this way, the end portion 5ae of the outer sheet 5a can be surely moved to the center side and the end side in the CD direction. As a result, the end of the outer cover sheet 5a on the absorbent body 3 can be surely provided. The position where the edge portion 3ee should be positioned until the position of the end edge portion 64e of the above-mentioned holding spacer 64 The P64e moves toward the CD.

===其他的實施例=== ===Other embodiments ===

以上，雖說明了本發明的實施例，但是上述的實施例，只是為了容易理解本發明，不是用來限定解釋本發明。且，本發明，是在不脫離其宗旨下，可變更和改良，並且在本發明中當然也包含其等價物。例如，可進行以下所示的變形。 The embodiments of the present invention have been described above, but the above-described embodiments are merely for ease of understanding of the present invention and are not intended to limit the present invention. Further, the present invention can be modified and improved without departing from the spirit and scope of the invention. For example, the following modifications can be made.

在上述的實施例中，雖對應外裝薄片5a的各端部5ae、5ae，各別設置端部位置檢出感測器50的照相機52、52，但是皆不限於此。例如，在各端部5ae、5ae的兩者之中只設置一台照相機52也可以。在此情況下，端部位置檢出感測器50的畫像處理部56，是使用平面畫像資料的一部分生成一方的端部5ae的位置資訊，使用同平面畫像資料的其他的一部分生成另一方的端部5ae的位置資訊。 In the above-described embodiment, the cameras 52 and 52 of the end position detecting sensor 50 are separately provided for the respective end portions 5ae and 5ae of the exterior sheet 5a, but are not limited thereto. For example, only one camera 52 may be provided in each of the end portions 5ae and 5ae. In this case, the image processing unit 56 of the end position detecting sensor 50 generates position information of one end portion 5ae using a part of the planar image data, and uses the other portion of the same plane image data to generate the other. Location information of the end 5ae.

在上述的實施例中，端部位置檢出感測器50的照相機52，雖是在壓輥43a、43b及折疊導引構件24之間攝像外裝薄片5a的各端部5ae，但是皆不限定於此，在比壓輥43a、43b更搬運方向的上游側將同端部5ae攝像也可以。 In the above-described embodiment, the camera 52 of the end position detecting sensor 50 photographs the end portions 5ae of the outer sheet 5a between the pressure rollers 43a and 43b and the folding guide member 24, but neither of them In this case, the same end portion 5ae may be imaged on the upstream side in the conveyance direction of the pressure rollers 43a and 43b.

在上述的實施例中，平面畫像資料的其中一例，顯示各畫素的顏色資訊是只有明度的灰階的資料，但是皆不限於此。例如，各畫素的色資訊是具有明度、色相、及彩度的彩色畫像資料也可以。且，在該情況中，前述的二值化處理，是進行彩色二值化處理也可以。 In the above-described embodiment, as an example of the planar image data, the color information of each pixel is displayed as only the grayscale of the brightness, but is not limited thereto. For example, the color information of each pixel may be color image data having brightness, hue, and chroma. And, in this case, the aforementioned binarization The processing is performed by performing color binarization processing.

且，彩色二值化處理，是從平面畫像的彩色畫像資料，將具有特定的色資訊的畫素抽出的處理。在此，顏色資訊，是使如前述明度、色相、及彩度的三要素各別具有數值。因此，對於明度、色相、及彩度，可各別將應抽出的畫素的顏色資訊的數值範圍，取代前述的門檻值預先設定在畫像處理部56的記憶體的話，畫像處理部56就可以將其被設定的色資訊的畫素從平面畫像抽出。 Further, the color binarization processing is a process of extracting pixels having specific color information from the color image data of the planar image. Here, the color information is such that the three elements of the aforementioned brightness, hue, and chroma have respective values. Therefore, in the case where the threshold value of the color information of the pixel to be extracted can be set in advance in the memory of the image processing unit 56, the image processing unit 56 can be used for the brightness, the hue, and the chroma. The pixels of the color information that is set are extracted from the planar image.

即，將上述的三個數值範圍，對於平面畫像之中胴周圍彈性構件設置部分5a8B被攝像的領域A5a8B依據特有的顏色預先設定好的話，畫像處理部56，是參照被記錄於平面畫像資料的平面畫像的各畫素的色資訊，且，將滿足上述的三個的數值範圍的全部的畫素抽出。且，依據此方法的話，因為是在上述胴周圍彈性構件設置部分5a8B被攝像的領域A5a8B依據特有的色，從平面畫像將同領域A5a8B抽出，所以可以提高其抽出精度。 In other words, when the three numerical ranges described above are set in advance in accordance with the specific color in the area A5a8B in which the surrounding elastic member mounting portion 5a8B is imaged in the plane image, the image processing unit 56 refers to the image data recorded in the plane image. The color information of each pixel of the plane image is extracted, and all the pixels satisfying the above three numerical ranges are extracted. In addition, according to this method, the field A5a8B in which the elastic member mounting portion 5a8B is imaged is extracted from the plane A5a8B in accordance with the characteristic color, so that the extraction accuracy can be improved.

在上述的實施例中，將端部位置檢出感測器50的照相機52相面對配置在外裝薄片5a的上面，將照明構件54相面對配置在其相反側也就是下面，但是此配置關係是相反也可以。即，將同照相機52相面對配置在下面，將照明構件54相面對配置在上面也可以。進一步說明的話，照相機52的攝像，不限定於來自任何外裝薄片5a的透過光的受光，即將來自外裝薄片5a的反射光受光攝像也可以。在此情況下，照明構件54，是對於外裝薄片5a被配置於與照相機52相同側，且，在畫像處理部56的記憶體的二值化處理的門檻值中，不用說當然也各別被設定成對應反射光的值。 In the above embodiment, the cameras 52 of the end position detecting sensor 50 are disposed facing each other on the outer sheet 5a, and the illumination members 54 are disposed facing each other on the opposite side, that is, below, but this configuration The relationship is the opposite. That is, the camera 52 may be disposed to face the lower side, and the illumination members 54 may be disposed to face each other. Further, the imaging of the camera 52 is not limited to the reception of the transmitted light from any of the exterior sheets 5a, and the reflected light from the exterior sheet 5a may be received by light. In this case, the illumination member 54 is provided for the exterior sheet 5a. It is placed on the same side as the camera 52, and it is needless to say that the threshold value of the binarization processing of the memory of the image processing unit 56 is set to a value corresponding to the reflected light.

在上述的實施例中，外裝薄片5a的其中一例，雖例示了具有外層薄片6a及內層薄片7a及彈性構件8B、8F、8L…的構成，但是皆不限定於此，即使沒有內層薄片7a或彈性構件8B、8F、8L…也可以。即，至少具備外層薄片6a即可。又，彈性構件8B、8F、8L…，可以例示例如橡膠線和伸縮性帶狀非織布、彈性帶狀薄片(薄膜)等。 In the above-described embodiment, the outer sheet 5a and the inner layer sheet 7a and the elastic members 8B, 8F, 8L, . . . are exemplified, but the outer layer 5a is not limited thereto, even if there is no inner layer. The sheet 7a or the elastic members 8B, 8F, 8L... may be used. That is, at least the outer layer sheet 6a may be provided. Further, the elastic members 8B, 8F, 8L, . . . may be exemplified by a rubber thread, a stretchable belt-shaped nonwoven fabric, an elastic belt-shaped sheet (film), and the like.
