　次に、ラベル装着装置３による容器ＢへのラベルＬの装着動作について、図１１及び図１２を参照して以下に説明する。 Next, the mounting operation of the label L on the container B by the label mounting device 3 will be described below with reference to FIGS. 11 and 12.
　図１１は、１つのラベル装着ヘッド３０を順に示す斜視図である。同図は、第１ラベル供給位置α１又は第２ラベル供給位置α２において、あるラベルＬがラベル受渡部３２１に供給された後、当該ラベルＬが容器Ｂに装着され、当該容器Ｂが搬出されるまでを示している。動作説明において着目するラベルＬは、理解の便宜上、ハッチングが付されている。また、図示された第１ラベル供給位置α１、第２ラベル供給位置α２、容器供給位置β及び容器搬出位置γと図１を参照して理解されるように、あるラベルＬが供給されてからこのラベルＬが装着された容器Ｂが搬出されるまでに、支持円盤３ａが１回転以上しており、本実施形態においては、おおよそ６００°回転している。 FIG. 11 is a perspective view showing one label mounting head 30 in order. In the figure, after a certain label L is supplied to the label delivery unit 321 at the first label supply position α1 or the second label supply position α2, the label L is attached to the container B, and the container B is unloaded. Show up. The label L focused on in the operation description is hatched for the convenience of understanding. Also, as illustrated with reference to the first label supply position α1 and the second label supply position α2, the container supply position β, and the container export position γ as illustrated with reference to FIG. By the time the container B on which the label L is mounted is unloaded, the support disk 3a is rotated by one or more rotations, and in the present embodiment, it is rotated approximately 600 degrees.
　まず、図１１（ａ）において、第１ラベル供給位置α１又は第２ラベル供給位置α２において第１ラベル中継ユニット５０Ａ又は第２ラベル中継ユニット５０Ｂからラベル受渡部３２１にラベルＬが供給される。ラベルＬは、ラベル受渡部３２１の搬送経路Ｔにおける下流側を向いた面に吸着保持される。なお、ラベル拡開ユニット３３は、着色されたラベルＬに先立って供給されたラベルＬをすでに保持している。 First, in FIG. 11A, the label L is supplied from the first label relay unit 50A or the second label relay unit 50B to the label delivery unit 321 at the first label supply position α1 or the second label supply position α2. The label L is held by suction on the downstream side of the transport path T of the label delivery unit 321. The label spreading unit 33 already holds the label L supplied prior to the colored label L.
　次いで、図１１（ｂ）においてラベル受渡部３２１が、第１ラベル中継ユニット５０Ａ又は第２ラベル中継ユニット５０Ｂから離間する。すると、カム溝３２６ｂおよびカム溝３３６ｂの形状にしたがって、ラベル受渡ユニット３２及びラベル拡開ユニット３３が下降する。これにより、図１１（ｃ）において、先立って供給されていたラベルＬが容器Ｂに装着される。この装着が完了すると、カム溝３３６ｂの形状にしたがって、ラベル拡開ユニット３３のみが上昇する。一方、ラベル受渡ユニット３２の高さは維持されている。 Next, in FIG. 11B, the label delivery unit 321 is separated from the first label relay unit 50A or the second label relay unit 50B. Then, the label delivery unit 32 and the label spreading unit 33 are lowered according to the shapes of the cam groove 326 b and the cam groove 336 b. As a result, the label L previously supplied is attached to the container B in FIG. When this mounting is completed, only the label spreading unit 33 is lifted according to the shape of the cam groove 336b. On the other hand, the height of the label delivery unit 32 is maintained.
　次いで、図１１（ｄ）に示すように、ラベル受渡ユニット３２のラベル受渡部３２１とラベル拡開ユニット３３の４つの吸引ロッド３３３の高さが重なる状態となる。この際、図１２（ａ）に示すように、一対ずつの開閉アーム３３２Ａ，３３２Ｂは、いずれも開状態である。そして、開状態の一対ずつの開閉アーム３３２Ａ，３３２Ｂの間に、ラベルＬを吸着保持したラベル受渡部３２１が位置する。なお、図１２においては、吸引力を発揮しているラベル受渡部３２１にハッチングを付している。 Next, as shown in FIG. 11D, the heights of the label delivery unit 321 of the label delivery unit 32 and the four suction rods 333 of the label expanding unit 33 overlap. At this time, as shown in FIG. 12A, the pair of open / close arms 332A and 332B are both in the open state. The label delivery unit 321 holding the label L by suction is positioned between the pair of open / close arms 332A and 332B. In FIG. 12, the label delivery unit 321 that exerts suction is hatched.
　次いで、図１１（ｅ）及び図１２（ｂ）に示すように、一対の開閉アーム３３２Ａのみを閉状態とする。また、一対の開閉アーム３３２Ａの吸引ロッド３３３の複数の吸引孔３３３ａから吸引する。これにより、ラベル受渡部３２１に吸引保持されたラベルＬは、一対の開閉アーム３３２Ａの吸引ロッド３３３にも吸引される。なお、理解の便宜上、図１２においては、吸引力を発揮している吸引ロッド３３３にハッチングを付している。そして、ラベル受渡部３２１の吸引を解除することにより、ラベルＬは、一対の開閉アーム３３２Ａの吸引ロッド３３３のみによって吸引保持される。 Next, as shown in FIGS. 11 (e) and 12 (b), only the pair of open / close arms 332A is closed. Further, suction is performed from a plurality of suction holes 333a of suction rods 333 of the pair of open / close arms 332A. Thus, the label L sucked and held by the label delivery unit 321 is also sucked by the suction rods 333 of the pair of open / close arms 332A. In addition, for convenience of understanding, in FIG. 12, the suction rod 333 exhibiting a suction force is hatched. Then, by releasing the suction of the label delivery unit 321, the label L is suctioned and held only by the suction rods 333 of the pair of open / close arms 332A.
　次いで、図１１（ｆ）及び図１２（ｃ）に示すように、一対の開閉アーム３３２Ａを開状態とする。この際、一対の開閉アーム３３２Ａの吸引ロッド３３３の吸引は維持しておく。これにより、ラベルＬが若干の湾曲形状となり、ラベル受渡部３２１から離間する。ラベルＬが離間したラベル受渡部３２１（ラベル受渡ユニット３２）は、カム溝３２６ｂの形状に伴い、上昇する。一方、ラベル拡開ユニット３３は、高さが維持される。 Next, as shown in FIGS. 11 (f) and 12 (c), the pair of open / close arms 332A are opened. At this time, the suction of the suction rod 333 of the pair of open / close arms 332A is maintained. As a result, the label L has a slightly curved shape, and is separated from the label delivery unit 321. The label delivery unit 321 (label delivery unit 32) with the label L separated is lifted with the shape of the cam groove 326b. On the other hand, the height of the label spreading unit 33 is maintained.
　次いで、図１１（ｇ）及び図１２（ｄ）に示すように、ラベル受渡部３２１（ラベル受渡ユニット３２）が上昇し、一対ずつの開閉アーム３３２Ａ，３３２Ｂの間から、ラベル受渡部３２１が退避する。また、容器供給位置βに到達したことにより、ラベル拡開ユニット３３の下方に、容器Ｂが供給されている。同図においては、４つの吸引ロッド３３３と容器Ｂとが高さ方向で重なっていないことを示すため、容器Ｂが想像線で示されている。 Next, as shown in FIGS. 11 (g) and 12 (d), the label delivery unit 321 (label delivery unit 32) ascends, and the label delivery unit 321 retracts from between the pair of open / close arms 332A and 332B. Do. Further, by reaching the container supply position β, the container B is supplied below the label spreading unit 33. In the figure, the container B is shown by imaginary lines in order to show that the four suction rods 333 and the container B do not overlap in the height direction.
　次いで、図１１（ｈ）及び図１２（ｅ）に示すように、一対ずつの開閉アーム３３２Ａ，３３２Ｂをそれぞれ閉状態とする。これにより、一対の開閉アーム３３２Ａと一対の開閉アーム３３２Ｂとによって、ラベルＬが挟まれた状態となる。また、この際に、一対の開閉アーム３３２Ｂの吸引ロッド３３３の吸引孔３３３ａからも吸引を開始しておく。これにより、ラベルＬは、一対の開閉アーム３３２Ａの吸引ロッド３３３と一対の開閉アーム３３２Ｂの吸引ロッド３３３との双方によって、吸着保持された状態となる。なお、第１ラベル供給位置α１又は第２ラベル供給位置α２において、次に処理されるラベルＬがラベル受渡部３２１に供給されている。 Next, as shown in FIGS. 11 (h) and 12 (e), the pair of open / close arms 332A and 332B are closed. As a result, the label L is sandwiched between the pair of opening and closing arms 332A and the pair of opening and closing arms 332B. At this time, suction is also started from the suction holes 333a of the suction rods 333 of the pair of open / close arms 332B. As a result, the label L is attracted and held by both the suction rod 333 of the pair of open / close arms 332A and the suction rod 333 of the pair of open / close arms 332B. A label L to be processed next is supplied to the label delivery unit 321 at the first label supply position α1 or the second label supply position α2.
　次いで、図１１（ｉ）及び図１２（ｆ）に示すように、一対ずつの開閉アーム３３２Ａ，３３２Ｂをそれぞれ開状態とする。ラベルＬは、筒状のフィルムが折り畳まれたものであるため、一対ずつの開閉アーム３３２Ａ，３３２Ｂの開動作により、図示されたような形態に拡開される。ラベルＬが拡開されると、カム溝３２６ｂ及びカム溝３３６ｂの形状に伴い、ラベル受渡ユニット３２及びラベル拡開ユニット３３が下降する。 Next, as shown in FIGS. 11 (i) and 12 (f), the pair of open / close arms 332A and 332B are opened. Since the label L is formed by folding a tubular film, the label L is expanded in the form as illustrated by the opening operation of the pair of open / close arms 332A, 332B. When the label L is expanded, the label delivery unit 32 and the label expansion unit 33 are lowered according to the shapes of the cam groove 326 b and the cam groove 336 b.
　次いで、図１１（ｊ）及び図１２（ｇ）に示すように、拡開されたラベルＬを吸着保持したラベル拡開ユニット３３が容器Ｂに対して下降することにより、ラベルＬが容器Ｂに徐々に被せられる。そして、ラベルＬが容器Ｂに対して所定高さまで到達すると、一対ずつの開閉アーム３３２Ａ，３３２Ｂの吸引ロッド３３３による吸引が解除される。これにより、容器ＢへのラベルＬの装着が完了する。 Next, as shown in FIG. 11 (j) and FIG. 12 (g), the label expanding unit 33 holding the expanded label L by suction is lowered relative to the container B, whereby the label L is transferred to the container B Be gradually put on. Then, when the label L reaches the container B to a predetermined height, the suction by the suction rods 333 of the pair of open / close arms 332A, 332B is released. Thereby, the attachment of the label L to the container B is completed.
　この後は、図１１（ｋ），（ｌ）に示すように、次に処理されるラベルＬに対して図１１（ｄ），（ｅ）を参照して説明した処理と同様の処理が行われ、図１１（ｍ）に示すように、容器搬出位置γにおいてラベルＬが装着された容器Ｂが、容器搬出装置４へと受け渡される。 Thereafter, as shown in FIGS. 11 (k) and 11 (l), the same process as described with reference to FIGS. 11 (d) and 11 (e) is performed on the label L to be processed next. As shown in FIG. 11 (m), the container B to which the label L is attached at the container unloading position γ is delivered to the container unloading device 4.
　以上に述べた、ラベル供給装置２からラベル中継装置５を経由したラベル装着装置３へのラベル供給動作と、ラベル装着装置３による容器ＢへのラベルＬの装着動作とが、順次行われることにより、複数の容器ＢへのラベルＬの装着が連続的に行われる。 The label supplying operation from the label supplying device 2 to the label attaching device 3 via the label relaying device 5 and the attaching operation of the label L to the container B by the label attaching device 3 are sequentially performed as described above The attachment of the label L to the plurality of containers B is continuously performed.
　次に、ラベル装着システムＡ１の作用について説明する。 Next, the operation of the label mounting system A1 will be described.
　本実施形態によれば、ラベル供給装置２からラベル中継装置５の第１ラベル中継ユニット５０Ａ及び第２ラベル中継ユニット５０Ｂを介して、ラベル装着装置３へとラベルＬが順次供給される。このため、第１ラベル中継ユニット５０Ａ及び第２ラベル中継ユニット５０Ｂのそれぞれが単位時間あたりに供給すべきラベルＬの数は、ラベル装着装置３が単位時間あたりに容器Ｂに装着すべきラベルＬの数の半分となる。このため、ラベル中継装置５の中継能力によって、ラベル装着装置３の装着能力が制限されることを回避することが可能である。したがって、ラベル装着システムＡ１によるラベル装着の高速化を図ることができる。 According to the present embodiment, the label L is sequentially supplied from the label supply device 2 to the label attachment device 3 through the first label relay unit 50A and the second label relay unit 50B of the label relay device 5. For this reason, the number of labels L that each of the first label relay unit 50A and the second label relay unit 50B should supply per unit time is the number of labels L that the label mounting device 3 should attach to the container B per unit time. It will be half of the number. For this reason, it is possible to avoid that the mounting capability of the label mounting device 3 is limited by the relay capability of the label relay device 5. Therefore, speeding up of label attachment by the label attachment system A1 can be achieved.
　ラベル受渡部３２１の複数の受渡吸引ロッド３２２と、ラベル中継部５１の複数の中継吸引ロッド５１１とが、互いに交互に位置するような配置であることにより、ラベル受渡部３２１とラベル中継部５１とをスムーズに交差させつつ、ラベルＬをより確実に受け渡しすることができる。 The plurality of delivery suction rods 322 of the label delivery unit 321 and the plurality of relay suction rods 511 of the label relay unit 51 are alternately positioned, whereby the label delivery unit 321 and the label relay unit 51 are provided. The label L can be more reliably delivered while smoothly crossing the
　また、図９に示すように、ラベル中継部５１は、上下方向に延びる２つの中継吸引ロッド５１１を有しており、ラベル受渡部３２１は、上下方向に延びる３つの受渡吸引ロッド３２２を有している。３つの受渡吸引ロッド３２２のうち径方向両端の２つの受渡吸引ロッド３２２は、２つの中継吸引ロッド５１１よりも径方向外側に位置している。これらの２つの受渡吸引ロッド３２２により、ラベルＬの幅方向（径方向）両端寄りの部分をより確実に吸引保持することができる。また、ラベルＬの幅方向（径方向）両端寄りの部分を確実に吸引保持可能であることから、ラベル受渡部３２１は、ラベルＬの下端付近を吸引保持することが必須ではない。このため、中継吸引ロッド５１１および中継連結部５１３よりも下方に、受渡吸引孔３２２ａを設ける必要がない。これは、中継連結部５１３をより低い位置に設けるのに都合が良く、図３に示すように、中継連結部５１３と径方向内側の吸引チャンバ２６７Ａ，２６７Ｂやベルト２６６Ａ，２６６Ｂとが干渉することを回避するのに適している。 Further, as shown in FIG. 9, the label relay unit 51 has two relay suction rods 511 extending in the vertical direction, and the label delivery unit 321 has three delivery suction rods 322 extending in the vertical direction. ing. Of the three delivery suction rods 322, two delivery suction rods 322 at both ends in the radial direction are located radially outward of the two relay suction rods 511. With these two delivery suction rods 322, it is possible to more reliably suction and hold the portion in the width direction (radial direction) of both ends of the label L. Further, since the portions near the both ends in the width direction (radial direction) of the label L can be reliably suctioned and held, it is not essential that the label delivery unit 321 suction and hold the vicinity of the lower end of the label L. For this reason, it is not necessary to provide the delivery suction hole 322a below the relay suction rod 511 and the relay connection portion 513. This is convenient for providing the relay connection portion 513 at a lower position, and as shown in FIG. 3, interference between the relay connection portion 513 and the radially inner suction chambers 267A, 267B and the belts 266A, 266B. Suitable to avoid.
　また、本実施形態においては、ラベル供給装置２が第１ラベル供給機構２０Ａ及び第２ラベル供給機構２０Ｂを含む。第１ラベル供給機構２０Ａは、第１ラベル中継ユニット５０ＡにラベルＬを供給し、第２ラベル供給機構２０Ｂは、第２ラベル中継ユニット５０ＢにラベルＬを供給する。このため、第１ラベル供給機構２０Ａ及び第２ラベル供給機構２０Ｂと同様に、第１ラベル供給機構２０Ａ及び第２ラベル供給機構２０Ｂのそれぞれが単位時間あたりに供給すべきラベルＬの数は、ラベル装着装置３が単位時間あたりに容器Ｂに装着すべきラベルＬの数の半分となる。このため、ラベル供給装置２の中継能力によって、ラベル装着装置３の装着能力が制限されることを回避することが可能である。したがって、ラベル装着システムＡ１によるラベル装着の高速化を図るのに好ましい。 Further, in the present embodiment, the label supply device 2 includes the first label supply mechanism 20A and the second label supply mechanism 20B. The first label supply mechanism 20A supplies the label L to the first label relay unit 50A, and the second label supply mechanism 20B supplies the label L to the second label relay unit 50B. For this reason, as with the first label supply mechanism 20A and the second label supply mechanism 20B, the number of labels L to be supplied per unit time by each of the first label supply mechanism 20A and the second label supply mechanism 20B is a label The mounting device 3 is half the number of labels L to be mounted on the container B per unit time. For this reason, it is possible to avoid that the mounting capability of the label mounting device 3 is limited by the relay capability of the label supplying device 2. Therefore, it is preferable to achieve speeding up of label attachment by the label attachment system A1.
　図５および図９に示すように、複数の中継吸引孔５１２が、鉛直方向に互いに離間した複数行に配置されていることにより、ラベルＬの鉛直方向両端寄りの部分をより確実に吸着することが可能である。これにより、中継吸引ロッド５１１に対してラベルＬがずれてしまう等の不具合を抑制可能であり、ラベル装着の高速化に好ましい。 As shown in FIG. 5 and FIG. 9, by arranging the plurality of relay suction holes 512 in a plurality of rows separated from each other in the vertical direction, it is possible to more reliably adsorb the portions near the both ends in the vertical direction of the label L Is possible. As a result, it is possible to suppress a defect such as the label L shifting with respect to the relay suction rod 511, which is preferable for speeding up the label attachment.
　図９に示すように、複数の中継吸引孔５１２と複数の受渡吸引孔３２２ａとが、鉛直方向に互いに離間した複数行に配置されてことにより、ラベル中継部５１からラベル受渡部３２１にラベルＬを受け渡す際に、ラベルＬをより確実に吸着することが可能であり、ラベル装着の高速化に好ましい。 As shown in FIG. 9, the plurality of relay suction holes 512 and the plurality of delivery suction holes 322a are arranged in a plurality of rows separated from each other in the vertical direction, whereby the label L from the label relay portion 51 to the label delivery portion 321 At the time of delivery, it is possible to adsorb the label L more reliably, which is preferable for speeding up of label attachment.
　図５に示すように、複数の中継吸引孔５１２は、２つの中継吸引ロッド５１１の径方向の外側と内側とに偏って配置されている。これにより、２つの中継吸引ロッド５１１のサイズや間隔を変えること無く、径方向におけるより広い領域においてラベルＬを吸着することが可能である。これは、ラベル装着の高速化に好ましい。 As shown in FIG. 5, the plurality of relay suction holes 512 are disposed to be biased radially outward and inward of the two relay suction rods 511. Thereby, it is possible to adsorb the label L in a wider area in the radial direction without changing the size and the distance between the two relay suction rods 511. This is preferable for speeding up of label attachment.
　図９に示すように、２つの中継吸引ロッド５１１の間に位置する受渡吸引ロッド３２２の複数の受渡吸引孔３２２ａは、径方向に互いに離間した複数列に配置されている。これにより、ラベルＬの受渡をより確実に行うことが可能であり、ラベル装着の高速化に好ましい。 As shown in FIG. 9, the plurality of delivery suction holes 322 a of the delivery suction rod 322 located between the two relay suction rods 511 are arranged in a plurality of rows mutually separated in the radial direction. Thereby, it is possible to more reliably deliver the label L, which is preferable for speeding up of label attachment.
　図１３～図２３は、本発明の他の実施形態を示している。なお、これらの図において、上記実施形態と同一又は類似の要素には、上記実施形態と同一の符号を付している。 13 to 23 show another embodiment of the present invention. In these figures, the same or similar elements as or to those of the above-described embodiment are denoted by the same reference numerals as those of the above-described embodiment.
＜第２実施形態＞
　図１３～図１５は、本発明の第２実施形態に係るラベル装着システムのラベル中継装置５を示している。本実施形態においては、中継吸引ロッド５１１に、複数の前方面５１５と複数の後方面５１６とが形成されている。 Second Embodiment
FIGS. 13 to 15 show a label relay device 5 of a label attachment system according to a second embodiment of the present invention. In the present embodiment, the relay suction rod 511 is provided with a plurality of front surfaces 515 and a plurality of rear surfaces 516.
　前方面５１５は、後方面５１６に対して搬送経路Ｔの下流側に位置する面である。後方面５１６は、前方面５１５に対して搬送経路Ｔの上流側に位置する面である。後方面５１６は、径方向に沿う溝状である。ラベル中継部５１によってラベルＬを吸着保持する際には、前方面５１５の方が後方面５１６よりも早いタイミングでラベルＬに当接すると想定される。 The front surface 515 is a surface located on the downstream side of the transport path T with respect to the rear surface 516. The rear surface 516 is a surface located on the upstream side of the transport path T with respect to the front surface 515. The rear surface 516 is in the form of a groove along the radial direction. When the label relay unit 51 sucks and holds the label L, it is assumed that the front surface 515 abuts the label L at a timing earlier than the rear surface 516.
　複数の前方面５１５と複数の後方面５１６とは、鉛直方向において交互に配置されている。複数の前方面５１５および複数の後方面５１６の個数は特に限定されず、図示された例においては、１つの中継吸引ロッド５１１に、４つの前方面５１５と３つの後方面５１６とが形成されている。 The plurality of front surfaces 515 and the plurality of rear surfaces 516 are alternately arranged in the vertical direction. The number of front surfaces 515 and the plurality of rear surfaces 516 is not particularly limited, and in the illustrated example, one relay suction rod 511 is formed with four front surfaces 515 and three rear surfaces 516. There is.
　図示された例においては、前方面５１５は、鉛直方向および径方向に沿う平坦面からなる。後方面５１６は、搬送経路Ｔの上流側に緩やかに凹む凹曲面からなる。ただし、前方面５１５および後方面５１６の具体的な形状は、何ら限定されない。また、２つの中継吸引ロッド５１１の複数の後方面５１６の鉛直方向位置は、互いに同一である。 In the illustrated example, the front surface 515 comprises a flat surface along the vertical and radial directions. The rear surface 516 is formed of a concave surface gently recessed on the upstream side of the transport path T. However, specific shapes of the front surface 515 and the rear surface 516 are not limited at all. Further, the vertical positions of the plurality of rear surfaces 516 of the two relay suction rods 511 are identical to each other.
　後方面５１６には、中継吸引孔５１２が開口している。図示された例においては、１つの後方面５１６に、鉛直方向に互いに離間した２つの中継吸引孔５１２が開口している。ただし、１つの後方面５１６に開口する中継吸引孔５１２の個数は特に限定されない。また、図示された例においては、２つの後方面５１６の間に位置する前方面５１５には、中継吸引孔５１２は開口していない。このため、この前方面５１５は、吸引機能を有さない。なお、複数の後方面５１６に挟まれていない前方面５１５には、中継吸引孔５１２が開口している。 The relay suction hole 512 is opened in the rear surface 516. In the illustrated example, in one rear surface 516, two relay suction holes 512 which are vertically separated from each other are opened. However, the number of relay suction holes 512 opened in one rear surface 516 is not particularly limited. Also, in the illustrated example, the relay suction hole 512 is not open at the front surface 515 located between the two rear surfaces 516. For this reason, this front surface 515 does not have a suction function. A relay suction hole 512 is opened in the front surface 515 which is not sandwiched by the plurality of rear surfaces 516.
　ここで、後方面５１６の寸法について説明する。図１４に示す後方面５１６の深さＤは、たとえば、０．１～２．０ｍｍであり、好ましくは、０．２～１．２ｍｍである。図１３および図１４に示す後方面５１６の中継吸引ロッド５１１の長手方向における寸法Ｈは、たとえば５～２０ｍｍであり、好ましくは８～１２ｍｍである。また、図１４に示す後方面５１６の曲率半径Ｒは、たとえば、８～６０ｍｍであり、好ましくは１２～４５ｍｍである。なお、図示された例においては、中継吸引ロッド５１１の径方向における幅Ｗが１２ｍｍであり、搬送経路Ｔに沿う方向である厚さ方向における厚さＴが１０ｍｍである。凹曲面によって構成された後方面５１６の具体的な寸法の一例を挙げると、寸法Ｈが１０ｍｍ、深さＤが１．０ｍｍ、曲率半径Ｒが１３ｍｍである。また、凹曲面によって構成された後方面５１６の具体的な寸法の他の例を挙げると、寸法Ｈが１０ｍｍ、深さＤが０．３ｍｍ、曲率半径Ｒが４２ｍｍである。 Here, the dimensions of the rear surface 516 will be described. The depth D of the rear surface 516 shown in FIG. 14 is, for example, 0.1 to 2.0 mm, preferably 0.2 to 1.2 mm. The dimension H in the longitudinal direction of the relay suction rod 511 of the rear surface 516 shown in FIGS. 13 and 14 is, for example, 5 to 20 mm, preferably 8 to 12 mm. The radius of curvature R of the rear surface 516 shown in FIG. 14 is, for example, 8 to 60 mm, preferably 12 to 45 mm. In the illustrated example, the width W of the relay suction rod 511 in the radial direction is 12 mm, and the thickness T in the thickness direction, which is a direction along the transport path T, is 10 mm. As an example of specific dimensions of the rear surface 516 configured by the concave surface, the dimension H is 10 mm, the depth D is 1.0 mm, and the curvature radius R is 13 mm. In addition, as another example of specific dimensions of the rear surface 516 configured by a concave surface, the dimension H is 10 mm, the depth D is 0.3 mm, and the curvature radius R is 42 mm.
　図１５は、搬送経路Ｔに沿って移動するラベル中継部５１によってラベルＬが保持された状態を示している。ラベルＬは、複数の中継吸引孔５１２による吸引力によって２つの中継吸引ロッド５１１に吸着されている。本実施形態においては、中継吸引ロッド５１１に後方面５１６が形成されている。後方面５１６は、径方向に沿う溝状である。ラベルＬが後方面５１６に沿った形状となることにより、ラベルＬには、湾曲部Ｌａが形成される。湾曲部Ｌａは、ラベルＬの一部が径方向に沿って緩やかに湾曲した部分である。湾曲部Ｌａの径方向視における形状は、おおむね後方面５１６の形状と類似する。ラベルＬに湾曲部Ｌａが形成されることにより、ラベルＬの径方向両側を折り曲げるような力に対する剛性が向上する。このため、ラベル中継部５１による搬送経路Ｔに沿った搬送において、ラベルＬのうち中継吸引ロッド５１１から径方向両側に延出した部分が、搬送経路Ｔの上流側（後方側）に折れてしまうことを抑制することが可能である。これにより、ラベル中継部５１の搬送速度を向上させることが可能であり、ラベル装着の高速化に有利である。 FIG. 15 shows a state in which the label L is held by the label relay unit 51 moving along the transport path T. The label L is adsorbed to the two relay suction rods 511 by the suction force of the plurality of relay suction holes 512. In the present embodiment, a rear surface 516 is formed on the relay suction rod 511. The rear surface 516 is in the form of a groove along the radial direction. Since the label L has a shape along the rear surface 516, a curved portion La is formed on the label L. The curved portion La is a portion where a part of the label L is gently curved along the radial direction. The shape of the curved portion La in the radial direction is generally similar to the shape of the rear surface 516. By forming the curved portion La on the label L, the rigidity against the force of bending the both sides in the radial direction of the label L is improved. For this reason, in the conveyance along the conveyance path T by the label relay unit 51, a portion of the label L which extends to both sides in the radial direction from the relay suction rod 511 is broken upstream (rearward) of the conveyance path T It is possible to suppress that. As a result, the transport speed of the label relay unit 51 can be improved, which is advantageous for speeding up of label attachment.
　後方面５１６に複数の中継吸引孔５１２が開口していることにより、ラベルＬを後方面５１６に沿うように、より確実に吸着することができる。これにより、より厚さが厚いラベルＬに湾曲部Ｌａを形成することが可能である。また、鉛直方向に離間した複数の後方面５１６が設けられていることにより、ラベルＬに複数の湾曲部Ｌａを形成することが可能である。これは、ラベルＬの剛性向上に好ましい。 By opening the plurality of relay suction holes 512 in the rear surface 516, the label L can be adsorbed more reliably along the rear surface 516. Thus, the curved portion La can be formed on the thicker label L. Further, by providing the plurality of rear surfaces 516 separated in the vertical direction, it is possible to form the plurality of curved portions La in the label L. This is preferable for improving the rigidity of the label L.
　また、２つの後方面５１６の間に位置する前方面５１５には、中継吸引孔５１２が開口していない。ラベルＬがラベル中継部５１に保持される際には、２つの後方面５１６の間に位置する前方面５１５にラベルＬが当接した後に、後方面５１６にラベルＬが当接すると想定される。この場合に、仮に前方面５１５に中継吸引孔５１２が開口していると、ラベルＬが後方面５１６の中継吸引孔５１２に吸着される前に、前方面５１５の中継吸引孔５１２によってラベルＬが拘束される可能性が高い。このような拘束は、ラベルＬが後方面５１６に沿うように吸着されることを阻害するおそれがあり、ラベルＬに湾曲部Ｌａが適切に形成されないことが懸念される。本実施形態においては、上述の前方面５１５に中継吸引孔５１２が形成されていないため、前方面５１５によってラベルＬが不当に拘束されてしまうことを抑制することができる。したがって、ラベルＬに湾曲部Ｌａを適切に形成することができる。 Also, in the front surface 515 located between the two rear surfaces 516, the relay suction hole 512 is not opened. When the label L is held by the label relay portion 51, it is assumed that the label L contacts the rear surface 516 after the label L contacts the front surface 515 located between the two rear surfaces 516. . In this case, if the relay suction hole 512 is open on the front surface 515, the label L is attached by the relay suction hole 512 on the front surface 515 before the label L is attracted to the relay suction hole 512 on the rear surface 516. It is likely to be tied up. Such restraint may inhibit the label L from being adsorbed along the rear surface 516, and there is a concern that the curved portion La may not be appropriately formed on the label L. In the present embodiment, since the relay suction hole 512 is not formed in the above-described front surface 515, it is possible to suppress the label L from being unduly restrained by the front surface 515. Therefore, the curved portion La can be appropriately formed on the label L.
　発明者らの試験例によれば、ＰＥＴ（ポリエチレンテレフタラート）からなり、厚さが２０μｍであるラベルＬを用いた場合であって、第１ラベル中継ユニット５０Ａおよび第２ラベル中継ユニット５０Ｂの周速が２２６ｍ／ｍｉｎであると、本実施形態とは異なり、後方面５１６を有さないラベル中継部５１に保持されたラベルＬは、径方向両端が折れる挙動が生じた。これに対し、本実施形態のラベル中継部５１によれば、同条件であってもラベルＬの径方向両端は折れなかった。発明者らの試験によれば、第１ラベル中継ユニット５０Ａおよび第２ラベル中継ユニット５０Ｂの周速が２００ｍ／ｍｉｎ以上であって、ＰＥＴからなるラベルＬの厚さが４０μｍ以下である場合に、後方面５１６による折れ防止効果が得られる傾向であることが確認された。 According to the test examples of the inventors, the label L made of PET (polyethylene terephthalate) and having a thickness of 20 μm is used, and the peripheries of the first label relay unit 50A and the second label relay unit 50B are used. Unlike the present embodiment, when the speed is 226 m / min, the label L held by the label relay portion 51 not having the rear surface 516 has a behavior in which both ends in the radial direction are broken. On the other hand, according to the label relay unit 51 of the present embodiment, both ends in the radial direction of the label L were not broken even under the same conditions. According to the tests of the inventors, when the circumferential speed of the first label relay unit 50A and the second label relay unit 50B is 200 m / min or more and the thickness of the label L made of PET is 40 μm or less, It was confirmed that the rear surface 516 tends to provide a fold preventing effect.

　本変形例によっても、ラベルＬに湾曲部Ｌａを形成することによりラベルＬの剛性を高めることが可能であり、ラベル装着の高速化に好ましい。また、本変形例から理解されるように、後方面５１６の個数は特に限定されず、ラベルＬの鉛直方向寸法や径方向寸法に応じて適宜設定可能である。 Also according to this modification, by forming the curved portion La on the label L, the rigidity of the label L can be enhanced, which is preferable for speeding up the label attachment.

FIG. 17 shows a second modification of the label relay unit 51 according to the second embodiment. In the present modification, the shape of the front surface 515 sandwiched between the two rear surfaces 516 is different from the example described above. In the present example, the front surface 515 is formed of a convex curved surface along the radial direction that is gently bulging toward the downstream side of the transport path T. That is, the downstream side portion of the transport path T of the relay suction rod 511 in the present example has a corrugated shape including a plurality of front surfaces 515 and rear surfaces 516.
　本変形例によっても、ラベルＬに湾曲部Ｌａを形成することによりラベルＬの剛性を高めることが可能であり、ラベル装着の高速化に好ましい。また、本変形例から理解されるように、前方面５１５および後方面５１６の形状は特に限定されず、適宜設定可能である。 Also according to this modification, by forming the curved portion La on the label L, the rigidity of the label L can be enhanced, which is preferable for speeding up the label attachment. Further, as understood from the present modification, the shapes of the front surface 515 and the rear surface 516 are not particularly limited, and can be set as appropriate.

　高摩擦部５１８は、中継吸引ロッド５１１とラベルＬとの摩擦力を高める部位である。図１９に示すように、図示された例においては、高摩擦部５１８は、中継吸引ロッド５１１の表面に微細な凹凸が形成されることによって設けられている。微細な凹凸からなる高摩擦部５１８を形成する手法は特に限定されず、本例においてはショットブラストが用いられている。 The high friction portion 518 is a portion that increases the frictional force between the relay suction rod 511 and the label L. As shown in FIG. 19, in the illustrated example, the high friction portion 518 is provided by forming fine irregularities on the surface of the relay suction rod 511. There is no particular limitation on the method of forming the high friction portion 518 composed of fine irregularities, and shot blasting is used in this example.
　図１８において、ハッチングを付した領域に高摩擦部５１８が設けられており、ラベル中継部５１の搬送経路Ｔにおける下流側部分全体に高摩擦部５１８が設けられている。高摩擦部５１８が設けられる領域は特に限定されず、たとえば前方面５１５のみに設けても良いし、後方面５１６のみに設けても良いし、あるいは前方面５１５の一部と後方面５１６の一部とに設けてもよい。 In FIG. 18, the high friction portion 518 is provided in the hatched region, and the high friction portion 518 is provided in the entire downstream side portion of the transport route T of the label relay portion 51. The area where the high friction portion 518 is provided is not particularly limited, and may be provided only on the front surface 515, may be provided only on the rear surface 516, or a part of the front surface 515 and the rear surface 516, for example. It may be provided in a part.
　このような実施形態によれば、高摩擦部５１８が設けられていることにより、中継吸引ロッド５１１とラベルＬとの摩擦力が高められる。このため、ラベルＬを保持した状態でラベル中継部５１を移動させる際に、風圧等によってラベルＬがラベル中継部５１に対してずれてしまうことを抑制することが可能である。したがって、ラベル装着の高速化を図るのに好ましい。 According to such an embodiment, the frictional force between the relay suction rod 511 and the label L is enhanced by providing the high friction portion 518. Therefore, when moving the label relay unit 51 while holding the label L, it is possible to suppress the label L from being displaced with respect to the label relay unit 51 due to wind pressure or the like. Therefore, it is preferable to achieve speeding up of label attachment.
