【０００７】 図１〜図６に於て、テーブル１周面の複数個所（図では８ケ所）に左右１対の 袋把持アーム２、２’を開閉自在に取付け、図示しない駆動手段によって間歇回 動出来るようになし、その間歇回動の過程で袋把持、開口、充填シール．．．等 の包装作業が行われる。1 to 6, a pair of left and right bag-holding arms 2 and 2 ′ are openably and closably attached to a plurality of places (8 places in the figure) on the circumferential surface of the table, and are intermittently moved by a driving means (not shown). It can be moved, and during the process of intermittent rotation, it holds the bag, opens, and fills the seal. ． ． Etc. are packaged.
【０００８】 本考案は上記把持アーム２、２’の爪３、３’の対向間隔ｌを各種袋４の巾寸 法に適宜自動合わせ出来るよう駆動モータの駆動により行われるようになすので あり、そのために袋把持アーム２、２’の開閉操作を行わしめるテーブル１下方 の全周カム５を垂直方向へ上下動するようになし、全周カム５と接するＬ状レバ ー１４の垂直線に対する接触角θ（図５参照）が変えられるようにして、対向す る把持アーム間の間隔ｌが適宜変えられるようになっており、具体的には次のよ うに構成される。The present invention is designed so that the facing distance l between the claws 3 and 3 ′ of the gripping arms 2 and 2 ′ can be automatically adjusted to the width dimension of each bag 4 by driving a drive motor. Therefore, the full-circumferential cam 5 below the table 1 for opening and closing the bag gripping arms 2 and 2'is vertically moved up and down, and the L-shaped lever 14 contacting the full-circumferential cam 5 makes contact with the vertical line. The angle θ (see FIG. 5) can be changed so that the interval l between the opposing gripping arms can be changed as appropriate, and is specifically configured as follows.
【０００９】 テーブル１の下方には、その円周端が垂直上方へ所定の高低差をつけて高く形 成された全周カム５が設けてあり、該全周カム５はテーブル１を間歇駆動させる 回転軸６に対し、これと一緒には回動しないで単に上下摺動のみ許容するように 嵌挿されている。 又、装置フレーム７に立設されたボス８の側面部に設けた軸承部１１には支点 １２を介して主レバー１０が取付けられているが、該主レバー１０の先端は全周 カム５の下面と係合させてあり、且つ基端は軸承部１１の下部へ回動自在に軸支 されたネジ軸９ａに螺合させるほか、該ネジ軸９ａの端部にはユニバーサルジョ イント等の接手３５及びロッド３６を介してモータ３７と連結してなり、該モー タ３７を駆動してネジ軸９ａを回転させると、主レバー１０が交点１２を中心に 回動して該レバー１０先端が係合した全周カム５を上下動させるようになってい る。Below the table 1, there is provided an all-peripheral cam 5 whose circumferential end is vertically formed upward with a predetermined height difference, and the all-peripheral cam 5 intermittently drives the table 1. The rotary shaft 6 is inserted so as to allow only vertical sliding without rotating together with the rotary shaft 6. Further, a main lever 10 is attached to a bearing portion 11 provided on a side surface portion of a boss 8 erected on the apparatus frame 7 via a fulcrum 12, but the tip of the main lever 10 is attached to the entire circumference of the cam 5. The base end is engaged with a screw shaft 9a that is rotatably supported on the lower part of the bearing 11, and the end of the screw shaft 9a has a joint such as a universal joint. When the motor 37 is driven to rotate the screw shaft 9a by rotating the screw shaft 9a, the main lever 10 rotates about the intersection 12 and the tip of the lever 10 engages. The combined all-round cam 5 is moved up and down.
【００１０】 一方、テーブル１の裏面からは全周カム５に向かって一定長の軸承函１３が垂 設してなり、その下端部にはＬ状レバー１４の隅角部ｋを（イ）、（ロ）方向に 搖動自在に軸支してなり、又該レバー１４の水平杆先端１４ａには自由回動する コロ１５が取付けられて全周カム５の円周端縁部上を滑動するようになされると 共に、垂直杆１４ｂの上端にも自由回動するコロ１６が取付けられて対向配置し た袋把持アーム２、２’の１つ（図示では２）の後部に突出形成した尾部ｍと当 設するようになっている。On the other hand, from the back surface of the table 1, a bearing box 13 having a constant length is hung down toward the all-round cam 5, and a corner portion k of the L-shaped lever 14 is provided at the lower end portion thereof. The lever 15 is pivotally supported in the (b) direction, and a freely rotating roller 15 is attached to the tip of the horizontal rod 14a of the lever 14 so that it slides on the circumferential end edge of the full circumference cam 5. At the same time, a freely rotating roller 16 is attached to the upper end of the vertical rod 14b, and a tail portion m formed to project at the rear portion of one of the bag holding arms 2 and 2 '(2 in the figure) that are arranged to face each other. It is supposed to be installed.
【００１１】 この際支持アーム２、２’はテーブル１の裏面部位置にピン１７、１７’によ り回動自在に取付けられる共に、夫々れの中央部位置にバネ１８を掛止して常時 その対向間隔ｌが矢印（ハ）、（ニ）方向へ狭められるように牽引され、且つこ のために上部把持アーム２の尾部ｍ側で矢印（ホ）方向へ拡がろうとするのを上 記垂直杆１４ｂのコロ１６で抑止するようになっている。 尚、もう一方の把持アーム２’と、上記把持アーム２とは内部中央位置で係合 するようになっており、そのため各把持アーム２、２’の対向する側面部位置に 支杆２ａ、２ａ’を一部が上下に重なり合うようになしてあり、また下部支杆２ ａ’には一定長さ範囲にスリット１９を穿設し、これに対し上部支杆２ａには係 止ピン２０を取付けて頭部を上方へ一定長さ突出させると共に、下部は上記支杆 ２ａ’のスリット１９内に嵌入させて係合させ、これにより袋把持アーム２’が 同調作動するようになしてある。At this time, the support arms 2 and 2 ′ are rotatably attached to the back surface of the table 1 by the pins 17 and 17 ′, and the springs 18 are hooked at the central positions of the support arms 2 and 2 ′, respectively. It is noted that the facing distance l is pulled so as to be narrowed in the arrow (c) and (d) directions, and for this reason, it tries to expand in the arrow (e) direction on the tail portion m side of the upper gripping arm 2. It is designed to be restrained by the roller 16 of the vertical rod 14b. The other gripping arm 2'and the above-mentioned gripping arm 2 are engaged with each other at an inner central position, so that the gripping arms 2a, 2a are supported by the supporting rods 2a, 2a. The upper support rod 2a is provided with a locking pin 20 while the lower support rod 2a 'is provided with a slit 19 in a certain length range. The head portion is projected upward by a certain length, and the lower portion is fitted into and engaged with the slit 19 of the supporting rod 2a ', whereby the bag gripping arm 2'is operated in synchronization.
【００１２】 一方テーブル１の回動軸６の先端部には星型カム２１が、その傾斜辺部ｆが上 記係止ピン２０の頭部と接触可能の状態に回動調整できるように設けてあり、又 この回動調整は摘み（２２）を適宜時計方向或いは反時計方向に回して行われる ようになっている。On the other hand, a star-shaped cam 21 is provided at the tip of the rotary shaft 6 of the table 1 so that the inclined side portion f can be rotationally adjusted so as to be in contact with the head of the locking pin 20. Further, this rotation adjustment is made by appropriately rotating the knob (22) in the clockwise or counterclockwise direction.
【００１３】 上記調整手段は図４にに示す如く、テーブル１に対し摘み２２を時計方向或い は反時計方向へ回動して、軸２３が上下動するよう軸２３の雄ネジと螺合する雌 ネジの内蔵された軸承部２４を設け、且つ軸２３の上端は星型カム２１の板面に 穿設した比較的大きい透孔２５から突出させると共に、軸下端はこれと少し離れ たテーブル１の一定長さ範囲にスリット２６を穿設し、該テーブル裏面部にコ字 状の軸承部２７をその内部溝ｇがスリット２６と対応一致するように固定し、軸 承部２７の内部溝ｇに対しＬ状レバー２８を矢印（ヘ）、（ト）方向へ搖動自在 に取付け、該Ｌ状レバー２８の水平杆端２８ａにはスライド用溝２９を穿設し、 前記摘み軸２３の下端に取付けた横杆３０が嵌入されて係合されるようになし、 又星型カム２１の上記内部溝ｇと直交する関係位置には一定長のスリット３１を 穿設すると共に、Ｌ状レバー２８の垂直杆２８ｂには上記スリット３１と摺動関 係になるようにされたコロ３２を備えた係合杆３３を取付けた構成となっている 。As shown in FIG. 4, the adjusting means rotates the knob 22 with respect to the table 1 clockwise or counterclockwise to screw the male screw of the shaft 23 so that the shaft 23 moves up and down. Is provided with a bearing portion 24 having a built-in female screw, and the upper end of the shaft 23 is projected from a relatively large through hole 25 formed in the plate surface of the star-shaped cam 21, while the lower end of the shaft is slightly separated from the table. 1, a slit 26 is bored in a fixed length range, and a U-shaped bearing portion 27 is fixed to the back surface of the table so that the internal groove g thereof corresponds to the slit 26, and the internal groove of the bearing portion 27 is fixed. An L-shaped lever 28 is attached to the g in such a manner that it can be swung in the directions of arrow (F) and (G), and a slide groove 29 is formed in a horizontal rod end 28a of the L-shaped lever 28. The horizontal rod 30 attached to the above is fitted and engaged, and A slit 31 of a constant length is formed at a relative position of the star-shaped cam 21 orthogonal to the internal groove g, and a vertical rod 28b of the L-shaped lever 28 is slidably engaged with the slit 31. An engaging rod 33 having a roller 32 is attached.
【００１４】 従って、摘み２２を回動して軸が上下動するとＬ状レバー２８がピン３４を支 点に矢印（ヘ）、（ト）方向へ搖動し、これに伴って係合杆３３がコロ３２を介 して星型カム２１を回動軸６の周りに矢印（チ）、（リ）方向へ回動させるので あるが、この際矢印（チ）方向へ回動すると星型カム２１の傾斜辺部ｆと係止ピ ン２０との対向間隔が接近するように、これに対し矢印（リ）方向へ回動すると 離間するように調整される。Therefore, when the knob 22 is rotated to move the shaft up and down, the L-shaped lever 28 swings in the directions of arrows (f) and (g) around the pin 34 as a fulcrum, and the engagement rod 33 accordingly. The star-shaped cam 21 is rotated around the rotation shaft 6 in the arrow (h) and (r) directions via the roller 32. At this time, when the star-shaped cam 21 is rotated in the arrow (h) direction, the star-shaped cam 21 is rotated. The slanted side portion f and the engaging pin 20 are adjusted so that the facing distance between them becomes close to each other, and when the slanted side portion f rotates in the direction of the arrow (r), the distance becomes apart.
【００１５】 次に本装置の作用を説明する。先づ袋把持アーム２，２’の巾間隔ｌを使用す る各種袋に応じて定めるが、その為モータ３７を駆動してネジ軸９ａを適宜時計 方向或いは反時計方向へ回動させる。この時主レバー１０が回動してその先端と 係合した全周カム５がＬ状レバー１４の水平杆１４ａ先端コロ１５を、その円周 端縁部の高所平坦部ｖ上へ位置させた状態で回動軸６の上下方向へ摺動し、この 摺動でＬ状レバー１４が矢印（イ）、（ロ）方向へ搖動し、垂直杆１４ｂのコロ １６と袋把持アーム２尾部ｍとの接触位置が変わるものになる。 例えば、モータ３７を時計方向へ回動して主レバー１０下部を図の右方へ移動 させると、該主レバー１０は支点１２を中止に左周りに搖動して全周カム５を上 昇させ、これに伴ってＬ状レバー１４が矢印（ロ）方向へ回動し、把持アーム２ 、２’間距離ｌが大きくなって袋巾間隔の大きい袋把持が行われ、これに対し反 時計方向へ回動させると全周カム５は下降し、これに伴ってＬ状レバー１４が矢 印（イ）方向へ回動して距離ｌが小さくなり、袋巾間隔の狭い袋把持が行われる ようになる。Next, the operation of this device will be described. The width l of the bag gripping arms 2 and 2'is determined depending on the type of bag to be used. Therefore, the motor 37 is driven to rotate the screw shaft 9a appropriately in the clockwise or counterclockwise direction. At this time, the main lever 10 is rotated to engage the entire circumference cam 5 with which the end of the horizontal rod 14a of the L-shaped lever 14 is positioned on the high flat part v of the circumferential edge. In this state, the rotary shaft 6 slides in the vertical direction, and the L-shaped lever 14 swings in the directions of arrows (a) and (b) by this sliding, and the roller 16 of the vertical rod 14b and the tail part 2 of the bag gripping arm 2m. The contact position with will change. For example, when the motor 37 is rotated in the clockwise direction to move the lower part of the main lever 10 to the right in the figure, the main lever 10 swings counterclockwise with the fulcrum 12 stopped, and the entire circumference cam 5 is raised. Along with this, the L-shaped lever 14 rotates in the direction of the arrow (b), the distance 1 between the gripping arms 2 and 2'becomes larger, and the bag is gripped with a large bag width interval. When it is rotated to, the entire-circumferential cam 5 is lowered, and accordingly, the L-shaped lever 14 is rotated in the direction of the arrow (a) to reduce the distance l, so that the bag can be gripped with a narrow bag width interval. become.
【００１６】 次に摘み２２を時計方向へ回動すると、Ｌ状レバー２８が矢印（ヘ）方向へ搖 動し、係合杆３３を介し星型カム２１が（チ）方向へ回動して傾斜辺部ｆと係合 ピン２０頭部との対向間隔が接近し、後述する充填物の投入位置に於ける袋口の 開口が縦方向で少な目に調整され、これに対し反時計方向に回動すると上記と反 対へ即ち星型カムが（リ）方向へ回動して傾斜辺部ｆと係合ピン２０頭部との対 向間隔が離れるようになって充填物の投入位置で袋口の開口が縦方向で大きく調 整されるものとなる。 図６は一種類の袋４が把持アーム２，２’間に把持され、テーブル１が８工程 の間歇回動する間に袋の開口、充填、シール等の実施状態を示す模式図であって 、工程１は給袋工程を、工程２は印字工程を、工程３は開口工程を、工程４は充 填工程を、工程５は閉口工程を、工程６はシール工程を、工程７は冷却工程を、 工程８は排出工程を夫々れ示す。Next, when the knob 22 is rotated clockwise, the L-shaped lever 28 swings in the arrow (f) direction, and the star-shaped cam 21 rotates in the (h) direction via the engaging rod 33. The facing distance between the inclined side portion f and the head of the engaging pin 20 becomes close, and the opening of the bag mouth at the filling material loading position described later is adjusted to a small degree in the vertical direction, while the counterclockwise rotation is performed. When it moves, the star-shaped cam rotates in the opposite direction, that is, in the (re) direction, so that the facing interval between the inclined side portion f and the head of the engaging pin 20 becomes larger, and the bag is placed at the position where the filler is loaded. The mouth opening will be greatly adjusted in the vertical direction. FIG. 6 is a schematic view showing a state in which a bag 4 of one type is held between the holding arms 2 and 2'and the table 1 is opened, filled, and sealed while the table 1 is rotated intermittently for 8 steps. , Step 1 is a bag feeding step, step 2 is a printing step, step 3 is an opening step, step 4 is a filling step, step 5 is a closing step, step 6 is a sealing step, step 7 is a cooling step. Step 8 shows each discharging step.

Along with this, the vertical rod 14b swings in the direction of the arrow (a), the facing distance between the bag gripping arms 2 and 2'is gradually narrowed by the pulling force of the spring 18, and the front and rear surfaces of the bag mouth p at this time. Are sucked by a suction cup (not shown) and pulled in the front-rear direction, and are successively opened in the longitudinal direction. At this time, the engaging pin 20 head is restricted by contact with the inclined side part f of the star-shaped cam 21. Then, the above operation is stopped.
