Description

本発明は、ラベルプリンタなどにより印字を施されて切断された単葉のタグを垂直状態に保持するとともに、水平方向に立ち並んで重なるよう収納するスタッカ装置およびその制御方法に関する。
The present invention relates to a stacker device that holds a single-leaf tag that has been printed and cut by a label printer or the like in a vertical state, and stores the tags so as to overlap each other in a horizontal direction, and a control method therefor.

従来、巻回されたロール状のタグ連続体やラベル連続体に対しプリンタにて印字を施した後、カッターなどの切断装置により所望長さの単葉のタグに切断するとともに、例えば、特許文献１に開示され、図６に示されるようなスタッカにスタック（収納）するようなことが行われている。
同図に示すスタッカによると、スタッカ４０は、プリンタ５０の発行口５１の下流に設置されており、プリンタ５０にて印字・発行された単葉のタグＴを積層して収納する。
先ず、プリンタ５０につき説明すると、プリンタ５０は、ロール状に巻回したタグ連続体Ｔｏを回転可能に保持する用紙供給軸５２と、サーマルヘッド５３およびプラテンローラ（以下、適宜、単に「プラテン」と称す）５４を備える印字機構５５と、リボンＲを回転可能に装着するリボン供給軸５６、およびリボン巻取り軸５７を備えるリボン機構５８と、切断機構５９とから構成される。
そして、例えばモータなどの図示せぬ駆動源によりリボン巻取り軸５７およびプラテン５４を駆動し、サーマルヘッド５３とプラテン５４の間に挿通されたタグ連続体Ｔｏを切断機構５９側へと搬送する途中で、印字機構５５にて図示省略の印字情報を必要枚数印字するようになっており、印字後のタグ連続体Ｔは切断機構５９にて切断され、単葉のタグＴとして発行口５１より発行されるようになっている。
プリンタ５０の発行口５１の下流に設置されているスタッカ４０は、プリンタ５０にて切断された単葉のタグＴを底板（底面）４１に引き込む引込機構４２を備えており、引込機構４２にてスタッカ４０側に引き込まれたタグＴは、引込機構４２の搬送方向Ｆ下流に配されている搬送ローラ４３にて底板４１に沿ってストッパ部４４まで搬送されるようになっており、タグＴは順次、タグＴの印字面とは反対の裏面側にもぐるように搬送されて底板４１に積層されるようになっている。
ところで、底板４１側にもぐり込むように積層されるタグＴが浮き上がらないよう、特許文献１にあっては、押圧片４４によってタグＴの印字面側（図６における上方）より所定の圧力を掛けるようになっている。
しかしながら、紙厚が厚いタグＴであれば底板４１へもぐり込み易いものの、紙厚の薄い、いわゆる、腰の弱いタグであると底板４１にもぐり込む際、折れ曲がって積層が乱れる虞があるという問題があり、積層ではなく縦（垂直状態）にタグを並べるスタッカの開発が望まれた。 2. Description of the Related Art Conventionally, after printing on a rolled roll-shaped tag continuum or label continuum with a printer, the printed tag is cut into single-leaf tags having a desired length by a cutting device such as a cutter. And stacking (accommodating) in a stacker as shown in FIG.

First, the printer 50 will be described. The printer 50 includes a paper supply shaft 52 that rotatably holds a tag continuous body To wound in a roll shape, a thermal head 53, and a platen roller (hereinafter simply referred to as “platen” as appropriate). A printing mechanism 55 including a ribbon 54, a ribbon supply shaft 56 for rotatably mounting the ribbon R, a ribbon mechanism 58 including a ribbon take-up shaft 57, and a cutting mechanism 59.
Then, the ribbon winding shaft 57 and the platen 54 are driven by a driving source (not shown) such as a motor, and the tag continuous body To inserted between the thermal head 53 and the platen 54 is being conveyed to the cutting mechanism 59 side. The printing mechanism 55 prints the required number of printing information (not shown), and the tag continuum T after printing is cut by the cutting mechanism 59 and issued from the issuing port 51 as a single-leaf tag T. It has become so.
The stacker 40 installed downstream of the issue port 51 of the printer 50 includes a pull-in mechanism 42 that pulls the single-leaf tag T cut by the printer 50 into the bottom plate (bottom surface) 41. The tag T drawn to the 40 side is conveyed to the stopper portion 44 along the bottom plate 41 by the conveyance roller 43 arranged downstream in the conveyance direction F of the drawing mechanism 42, and the tags T are sequentially arranged. The tag T is conveyed so as to go to the back side opposite to the printing surface of the tag T and is laminated on the bottom plate 41.
By the way, in Patent Document 1, a predetermined pressure is applied from the printing surface side (upper side in FIG. 6) of the tag T by the pressing piece 44 so that the tag T stacked so as to go into the bottom plate 41 side does not float. It has become.
However, if the tag T has a large paper thickness, it is easy to slip into the bottom plate 41. However, if the tag has a thin paper thickness, that is, a weak tag, the tag may be bent and the stacking may be disturbed. Therefore, it was desired to develop a stacker in which tags are arranged vertically (in a vertical state) rather than stacked.

ガイド部材１５よりロック部材１６が徐々に退動し、ロック部材１６の先端部が山部１５ａより退動すると、ロック部材１６とガイド部材１５との係合（ロック）が外れ、押圧部３の第１の付勢部材１２の作用（反発力）により支持部材１３が搬送方向Ｆに移動してロック部材１６がガイド部材１５の山部１５ａを越えるとともに、ロック部材１６と進退動部材１１の係合が解除される。
ロック部材１６と進退動部材１１との係合が解除されたことにより、第２の付勢部材１７が山部１５ａを越えたロック部材１６を再びガイド部材１５の谷部１５ｂ側へ付勢して進出する。
なお、第２の付勢部材１７は、「コイルバネ」などで作製されている。 As shown in FIG. 2, the slide means 7 mainly includes a guide portion 15 that extends in the transport direction F, a lock member 16 that engages with the guide member 15, and a second urging member 17. With.
The guide member 15 is formed in a sawtooth shape by alternately arranging peaks 15 a and valleys 15 b, and the lock member 16 is engaged with the valleys 15 b of the guide 15. Note that a predetermined distance called 1 pitch P is provided between the valley 15b and the adjacent valley 15b.
The locking member 16 has an inclined surface 16b whose tip end portion is substantially the same as the “inclined surface” extending from the peak portion 15a of the guide portion 15 to the valley portion 15b, and in the middle of the longitudinal direction. A slide surface 16a is formed, and is provided in a direction substantially orthogonal to the advance / retreat member 11.
The second urging member 17 is interposed between the lock member 16 and the support member 13 so as to constantly urge the lock member 16 toward the guide portion 15 side. When the member 16 advances, the lock member 16 is engaged with the guide member 15. Since the inclined surface 16b at the tip of the locking member 16 has a shape that is substantially the same as the “inclined surface” that extends from the peak portion 15a of the guide portion 15 to the valley portion 15b, the lock member 16 is locked when positioned on the valley portion 15b. The engaged state of the member 16 is ensured.

When the lock member 16 is gradually retracted from the guide member 15 and the distal end portion of the lock member 16 is retracted from the peak portion 15a, the engagement (lock) between the lock member 16 and the guide member 15 is released, and the pressing portion 3 The support member 13 is moved in the transport direction F by the action (repulsive force) of the first urging member 12 so that the lock member 16 exceeds the peak portion 15a of the guide member 15 and the engagement between the lock member 16 and the advance / retreat member 11 is increased. The match is released.
When the engagement between the lock member 16 and the advancing / retracting member 11 is released, the second urging member 17 urges the lock member 16 beyond the peak portion 15a again to the valley portion 15b side of the guide member 15. To advance.
The second biasing member 17 is made of a “coil spring” or the like.

次に、主に、図１ないし図５に基づき、スタッカ装置１の作動状態を説明する。
図５は、押圧板１０とストッパ板５の間に形成されたタグ収納部６に単葉のタグＴが縦に立ち並んで収納されている状態を示す概略側面説明図である。
引込み・搬送部２にてプリンタ５０の発行口５１より発行された単葉のタグＴを下流（搬送方向Ｆ）側に搬送する。すなわち、図示省略のモータを介してローラ８ａ、８ｂを回転し、ベルト９ａ、９ｂの間に挟持したタグＴを引込み・搬送部２の先端部に搬送する。
１枚目のタグＴをタグ収納部６に収納する状況を、図３に基づき説明すると、引込み・搬送部２の先端部に搬送されたタグＴは、引き続いて回転するベルト９ａ、９ｂにより垂直に近い状態で押圧板１０とストッパ板５との間（タグ収納部６）に押し出される。
搬送方向Ｆ下流に立設される押圧板１０と、対峙して立設するストッパ板５との間には、ストッパ板５の上端部より底面部４に向けてテーパー面が形成された板バネ１４が介在するため、引込み・搬送部２より押し出されたタグＴは、板バネ１４のテーパー面および押圧板１０に沿って板バネ１４の弾性力（撓み）により円滑に底面部４へと押し込まれるとともに、押圧板１０とストッパ板５との間にて縦に立った状態で底面部４に載置される。
２枚目以降は、押圧板１０とストッパ板５の間に立って載置されたタグＴが押圧板１０の代わりとなって、引込み・搬送部２の先端部より押し込まれたタグＴの「案内面」としての役目を果たすようになっており、タグＴと板バネ１４のテーパー面に沿って次のタグＴを底面部４へと押し込むものである。
タグＴの発行が進み、タグ収納部６にタグＴが順次、搬送されて押し込まれると押圧板１０が第１の付勢部材１２の押圧力に抗して徐々に搬送方向Ｆへ退動（後退）する。
この押圧板１０の退動時の状態を、主に、図４に基づき説明する。タグ収納部６へのタグＴの収納が進むと、押圧板１０をその先端部に取り付けるとともに、後端部にテーパー面１１ａを形成してなる進退動部材１１が搬送方向Ｆに退動し、進退動部材１１とほぼ直交する方向に設けられているロック部材１６のスライド面１６ｂに摺接する。更に、進退動部材１１は退動しながらテーパー面１１ａをスライド面１６ｂに摺接し、テーパー面１１ａに沿ってロック部材１６を徐々に矢示Ｕ方向に退動する。
ロック部材１６が第２の付勢部材１７の付勢力に抗して矢示Ｕ方向に退動すると、主に、図２に示すように、ガイド部材１５の谷部１５ｂに係合していた先端部が徐々に退動（後退）し、ロック部材１６の先端部が山部１５ａより退動すると、ロック部材１６とガイド部材１５との係合（ロック）が外れ、押圧部３の第１の付勢部材１２の作用（反発力）により支持部材１３がストッパ板５から離反する方向（搬送方向Ｆ）に移動してロック部材１６がガイド部材１５の山部１５ａを越えるとともに、ロック部材１６と進退動部材１１の係合が解除され、さらに、ロック部材１６と進退動部材１１の係合の解除に伴い、今度は第２の付勢部材１７がロック部材１６をガイド部材１５側へ付勢するものであり、付勢されたロック部材１６は、先端部の傾斜面１６ｂが、ガイド部１５の山部１５ａより谷部１５ｂへ至る「傾斜面」とほぼ同様の形状となっているため、次の１ピッチＰ分、隣の谷部１５ｂ側へ円滑に滑るとともに、谷部１５ｂに位置決めされた際、ロック部材１６の係合状態が確実となるものである。
図５は、タグ収納部６へのタグＴの収納、押圧板１０および進退動部材１１の退動（搬送方向Ｆへの後退）、進退動部材１１のテーパー面１１ａとロック部材１６のスライド面１６ｂとの摺接、ロック部材１６の退動（矢示Ｕ方向への後退）、ロック部材１６とガイド部材１５との係合（ロック）解除、第２の付勢部材１７の付勢によるロック部材１６とガイド部材１５との係合（ロック）、押圧部３およびスライド手段７の、１ピッチＰ分の搬送方向Ｆへの移動、を繰り返した状態を示している。 Next, the operation state of the stacker device 1 will be described mainly based on FIGS. 1 to 5.
FIG. 5 is an explanatory schematic side view showing a state in which single-leaf tags T are stored vertically in a tag storage portion 6 formed between the pressing plate 10 and the stopper plate 5.
The single-leaf tag T issued from the issuing port 51 of the printer 50 is conveyed downstream (in the conveying direction F) by the drawing / conveying unit 2. That is, the rollers 8 a and 8 b are rotated via a motor (not shown), and the tag T sandwiched between the belts 9 a and 9 b is conveyed to the leading end of the drawing / conveying unit 2.
The situation in which the first tag T is accommodated in the tag accommodating portion 6 will be described with reference to FIG. 3. The tag T conveyed to the leading end of the retracting / conveying portion 2 is vertically moved by the belts 9a and 9b that are continuously rotated. In the state close | similar to, it pushes out between the press board 10 and the stopper board 5 (tag accommodating part 6).

And placed on the bottom surface portion 4 while standing vertically between the pressing plate 10 and the stopper plate 5.
In the second and subsequent sheets, the tag T placed between the pressing plate 10 and the stopper plate 5 serves as a substitute for the pressing plate 10 and “ It serves as a “guide surface” and pushes the next tag T into the bottom surface portion 4 along the tapered surfaces of the tag T and the leaf spring 14.
When the tag T is issued and the tags T are sequentially conveyed and pushed into the tag storage 6, the pressing plate 10 gradually retracts in the conveying direction F against the pressing force of the first urging member 12 ( fall back.
The state when the pressing plate 10 is retracted will be described mainly with reference to FIG. When the storage of the tag T in the tag storage part 6 proceeds, the pressing plate 10 is attached to the tip part thereof, and the advancing / retracting member 11 formed with the tapered surface 11a at the rear end part is retracted in the transport direction F, The sliding contact is made with the sliding surface 16b of the lock member 16 provided in a direction substantially orthogonal to the advance / retreat member 11. Further, the advancing / retreating member 11 slides the taper surface 11a on the slide surface 16b while retreating, and gradually moves the lock member 16 in the arrow U direction along the taper surface 11a.
When the lock member 16 retreats in the direction indicated by the arrow U against the urging force of the second urging member 17, it was mainly engaged with the valley 15b of the guide member 15 as shown in FIG. When the distal end portion is gradually retracted (retracted) and the distal end portion of the lock member 16 is retracted from the peak portion 15a, the engagement (lock) between the lock member 16 and the guide member 15 is released, and the first portion of the pressing portion 3 is released. Due to the action (repulsive force) of the urging member 12, the support member 13 moves in the direction away from the stopper plate 5 (conveying direction F), so that the lock member 16 exceeds the peak portion 15 a of the guide member 15 and the lock member 16. The engagement of the advance / retreat member 11 is released, and the second urging member 17 applies the lock member 16 to the guide member 15 side in accordance with the release of the engagement of the lock member 16 and the advance / retreat member 11. The biased lock member 16 is Since the inclined surface 16b of the portion has substantially the same shape as the “inclined surface” extending from the peak portion 15a of the guide portion 15 to the valley portion 15b, the next one pitch P is smoothly moved to the adjacent valley portion 15b side. And the engagement state of the lock member 16 is ensured when positioned in the valley 15b.
FIG. 5 shows storage of the tag T in the tag storage unit 6, retraction of the pressing plate 10 and the advance / retreat member 11 (retreat in the transport direction F), the taper surface 11 a of the advance / retreat member 11 and the slide surface of the lock member 16. Locking by sliding contact with 16b, retraction of lock member 16 (retraction in the direction indicated by arrow U), engagement (lock) release of lock member 16 and guide member 15, and urging of second urging member 17 The state where the engagement (locking) of the member 16 and the guide member 15 and the movement of the pressing portion 3 and the sliding means 7 in the transport direction F by one pitch P is repeated is shown.

上述したように、引込み・搬送部２にてタグＴを押圧板１０とストッパ板５との間に形成されたタグ収納部６に垂直方向に押し込み、タグ収納部６にタグＴが所定量、押し込まれた際、ストッパ板５より離反する方向（搬送方向Ｆ）に押圧部３を押圧板１０ごと１ピッチＰ分だけ移動するので、簡単な構造で、タグＴの縦への押し込みが容易となり、かつ、第１の付勢部材１２を介して一定の圧力を付与する押圧板１０と板バネ１４を備えたストッパ板５との間にて、縦に押し込まれたタグＴを挟持するので、タグは水平方向に立ち並んで重なるように収納されるものである。 As described above, the tag T is pushed in the tag storage unit 6 formed between the pressing plate 10 and the stopper plate 5 in the vertical direction in the retracting / conveying unit 2, and the tag T is inserted into the tag storage unit 6 by a predetermined amount. When pushed, the pressing portion 3 is moved by one pitch P together with the pressing plate 10 in the direction away from the stopper plate 5 (conveying direction F), so that the tag T can be easily pushed vertically with a simple structure. And, since the tag T pushed vertically is sandwiched between the pressing plate 10 that applies a constant pressure via the first urging member 12 and the stopper plate 5 having the plate spring 14, The tags are stored so as to overlap each other in the horizontal direction.
