As shown in FIG. 6, in the rotary packaging machine, the pair of first sandwiching arms 10a and 10b and the pair of second sandwiching arms 11a and 11b are sequentially transferred to the packaging bag (9) and opened (see FIG. 6). 1), bottom opening (2), bag opening (3), product filling (4), product pushing (5), defective product discharge (6), bag port seal (7), product discharge (8 ) To create a product packaging bag.
FIG. 1 shows a pair of first clamping arms 10a and 10b and a pair of second clamping arms 11a and 11b in product filling (4) and product pushing (5) in order to distinguish them from the first clamping arms. And a link mechanism. FIG. 2 is a plan view of the second holding arms 11a and 11b at the time of product filling (4) and a plan sectional view of the first holding arms 10a and 10b at the time of product pushing (5). 3A is a cross-sectional view taken along lines C-C and D-D in FIG. 1, FIG. 3B is a right side view of FIG. 3A, and FIG. A and BB sectional drawing and FIG.4 (B) are the right view of FIG. 4 (A).

第１挟持腕１０ａと第１挟持腕１０ｂは同じ構造であるので、第１挟持腕１０ａについて説明する。尚、これら第１挟持腕１０ａ、１０ｂおよび第２挟持腕１１ａ、１１ｂの構造はよく知られているので概略説明する。
第１挟持腕１０ａは、先端の可動する挟持爪１５ｂと固定爪１５ａとで、包装袋１の側部を挟持し、常時、前記挟持爪１５ｂは弾性体１４で押し付けられて、挟持状態を維持している。
一方、挟持爪１５ｂと固定爪１５ａとで、挟持状態の包装袋を落下させるときには、操作レバー１３で開口体１２を包装機の中心方向に押圧することにより、リンク体１２ａが回動し、挟持爪１５ｂが回動軸１５ｃを軸心に旋回し、固定爪１５ａと挟持爪１５ｂが開くことによって行われる。 Since the first clamping arm 10a and the first clamping arm 10b have the same structure, the first clamping arm 10a will be described. In addition, since the structure of these 1st clamping arms 10a and 10b and 2nd clamping arms 11a and 11b is well known, it is demonstrated roughly.
The first clamping arm 10a clamps the side portion of the packaging bag 1 with a movable claw 15b and a fixed claw 15a at the tip, and the clamping claw 15b is always pressed against the elastic body 14 to maintain the clamping state. is doing.
On the other hand, when dropping the sandwiched packaging bag with the sandwiching claws 15b and the fixed claws 15a, the link body 12a is rotated and sandwiched by pressing the opening body 12 toward the center of the packaging machine with the operation lever 13. The claw 15b rotates around the rotation shaft 15c, and the fixed claw 15a and the clamping claw 15b are opened.

前記第１挟持腕１０ａは、固定されている左挟持軸１６ａで回動可能な左レバー１６Ａに取り付けてあり、他方の第１挟持腕１０ｂは、固定されている右挟持軸１６ｂで回動可能な右レバー１６Ｂに取り付けられている。
又、前記第１挟持腕１０ａ、１０ｂの間には、引張りバネ１７によって相互に牽引されていると共に、前記左レバー１６Ａと右レバー１６Ｂの回転方向は、互いに逆回転となるように連結部材１８でリンク結合してある。
即ち、第１挟持腕１０ａと第１挟持腕１０ｂ、第２挟持腕１１ａと第２挟持腕１１ｂは、互いに逆方向に回動する。 The first clamping arm 10a is attached to a left lever 16A that can be rotated by a fixed left clamping shaft 16a, and the other first clamping arm 10b is rotatable by a fixed right clamping shaft 16b. Is attached to the right lever 16B.
Further, the first clamping arms 10a and 10b are mutually pulled by a tension spring 17, and the connecting member 18 so that the rotation directions of the left lever 16A and the right lever 16B are opposite to each other. It is linked with.
That is, the first clamping arm 10a and the first clamping arm 10b, and the second clamping arm 11a and the second clamping arm 11b rotate in opposite directions.

次に、第１挟持腕１０ａと第１挟持腕１０ｂ、第２挟持腕１１ａと第２挟持腕１１ｂがなす基準挟持角を設定する基準挟持角機構について説明する。
前記左レバー１６Ａの端部は、端部が前記左挟持軸１６ａで回動可能に取り付けてあるレバー２０に、ピン１６ｃで結合されている。又、前記レバー２０の他端部は、連結軸２１ａで回動可能にリンク体２１の端部と結合してあり、更に、そのリンク体２１の他端部は連結軸２１ｂで回動可能に開閉リンク体２２の端部に連結してある。
又、開閉リンク体２２の他端部は、前記左挟持軸１６ａで回動可能に取り付けてある開閉レバー２３に連結軸２２ａで回動可能に取り付けてあり、前記レバー２０、リンク体２１、開閉リンク体２２及び開閉レバー２３とで四節リンクを構成している。 Next, a reference clamping angle mechanism for setting a reference clamping angle formed by the first clamping arm 10a and the first clamping arm 10b, and the second clamping arm 11a and the second clamping arm 11b will be described.
The end of the left lever 16A is coupled to a lever 20 having an end rotatably attached to the left clamping shaft 16a by a pin 16c. The other end of the lever 20 is coupled to the end of the link body 21 so as to be rotatable by a connecting shaft 21a, and the other end of the link body 21 is rotatable by a connecting shaft 21b. The end of the opening / closing link body 22 is connected.
The other end of the opening / closing link body 22 is attached to an opening / closing lever 23 rotatably attached to the left pinching shaft 16a so as to be rotatable about the connecting shaft 22a. The link body 22 and the opening / closing lever 23 form a four-bar link.

又、前記連結軸２１ｂには、幅調節リンク体２６が回動可能に取り付けてあり、その幅調節リンク体２６の他端部は、連結軸２８ａを介して、回転可能な調整輪２８に連結してある。即ち、この調整輪２８を回動して連結軸２８ａの位置を変更すると、前記幅調節リンク体２６、四節リンクのレバー２０、リンク体２１、開閉リンク体２２及び開閉レバー２３を介して、前記第１挟持腕１０ａの挟持角、及び、前記連結部材１８を介して前記第１挟持腕１０ｂの挟持角の変更、即ち、包装袋１を挟着する幅（基準挟持角）の変更が可能である。   A width adjusting link body 26 is rotatably attached to the connecting shaft 21b, and the other end of the width adjusting link body 26 is connected to a rotatable adjusting wheel 28 via a connecting shaft 28a. It is. That is, when the adjustment wheel 28 is rotated to change the position of the connecting shaft 28a, the width adjusting link body 26, the four-bar link lever 20, the link body 21, the opening / closing link body 22 and the opening / closing lever 23 are used. It is possible to change the clamping angle of the first clamping arm 10a and the clamping angle of the first clamping arm 10b via the connecting member 18, that is, the width (reference clamping angle) for clamping the packaging bag 1. It is.

前記記載の基準挟持角を設定する基準挟持角機構は、調整輪２８、幅調節リンク体２６、四節リンク（レバー２０、リンク体２１、開閉リンク体２２及び開閉レバー２３）であり、第１挟持腕１０ａ、１０ｂの他に、後記で記載する第２幅調節リンク体２６を前記調整輪２８に結合させると、共通の調整輪２８の回動によって、第２挟持腕１１ａ、１１ｂの挟持角の調整もできる。
尚、前記第１挟持腕１０ａ、１０ｂと第２挟持腕１１ａ、１１ｂの基準挟持角調整機構を、それぞれ独立して挟持角の調整ができるように、調整輪２８と幅調節リンク体２６を各々備えることによって構成することもできる。 The reference clamping angle mechanism for setting the reference clamping angle is the adjustment wheel 28, the width adjustment link body 26, and the four-bar link (the lever 20, the link body 21, the opening / closing link body 22, and the opening / closing lever 23). In addition to the holding arms 10a and 10b, when a second width adjusting link body 26 described later is coupled to the adjusting wheel 28, the holding angle of the second holding arms 11a and 11b is caused by the rotation of the common adjusting wheel 28. Can also be adjusted.
The adjusting wheel 28 and the width adjusting link body 26 are respectively adjusted so that the reference holding angle adjusting mechanism of the first holding arms 10a and 10b and the second holding arms 11a and 11b can be adjusted independently. It can also be configured by providing.

また、前記基準挟持角機構の操作として、例えば、前記調整輪２８を時計方向に回動すると、前記四節リンクのレバー２０、即ち、ピン１６ｃで結合してある前記左レバー１６Ａは反時計方向に回動して、第１挟持腕１０ａ、１０ｂの挟持角は大きくなり、反対に、前記調整輪２８を反時計方向に回動すると、第１挟持腕１０ａ、１０ｂの挟持角は小さくなる。   Further, as an operation of the reference clamping angle mechanism, for example, when the adjusting wheel 28 is rotated clockwise, the lever 20 of the four-bar link, that is, the left lever 16A coupled by the pin 16c is counterclockwise. When the adjusting wheel 28 is turned counterclockwise, the holding angle of the first holding arms 10a and 10b is reduced.

次に、前記第１挟持腕１０ａ、１０ｂが基準挟持角にセットされている状態において、挟持爪１５ｂと固定爪１５ａを振動させる振動装置について説明する。
前記開閉レバー２３の端部には、開閉ローラ２４が取り付けてあり、順次、第１挟持腕１０ａ、１０ｂが各工程毎に回転するに伴って、固定されている開閉円板体（尚、この実施例では上開閉円板体（上カム））２７と摺動回転して、前記調整された挟持角に対して、第１挟持腕１０ａ、１０ｂの挟持角を大きくして包装袋を閉状態にしたり、挟持角を小さくして包装袋を開状態にする。即ち、上開閉円板体（上カム）２７の形状に従って、第１挟持腕１０ａ、１０ｂの挟持角が変更される。そこで、上開閉円板体（上カム）２７の周縁部に凹凸１００ａを形成しておくと、その凹凸１００ａによって、第１挟持腕１０ａ、１０ｂの挟持角の変更ができ、即ち、包装袋の側部を挟持している挟持爪１５ｂの往復動が行われて、包装袋に振動を与えることができる。
尚、第２挟持腕１１ａ、１１ｂの開閉機構は、前記、第１挟持腕１０ａ、１０ｂと同じであるので説明を略す。 Next, a vibration device that vibrates the clamping claw 15b and the fixed claw 15a in a state where the first clamping arms 10a and 10b are set at the reference clamping angle will be described.
An opening / closing roller 24 is attached to an end portion of the opening / closing lever 23, and the opening / closing disk body (which is fixed as the first clamping arms 10a, 10b rotate in each step in turn) In the embodiment, the packaging bag is closed by sliding and rotating with the upper opening / closing disk (upper cam) 27 to increase the holding angle of the first holding arms 10a and 10b with respect to the adjusted holding angle. Or reduce the holding angle to open the packaging bag. That is, according to the shape of the upper opening / closing disc body (upper cam) 27, the clamping angle of the first clamping arms 10a, 10b is changed. Therefore, if the unevenness 100a is formed on the peripheral portion of the upper opening / closing disc body (upper cam) 27, the unevenness 100a can change the holding angle of the first holding arms 10a, 10b, that is, the packaging bag A reciprocating motion of the clamping claws 15b that clamp the side portions is performed, and vibration can be applied to the packaging bag.
The opening / closing mechanism of the second holding arms 11a and 11b is the same as that of the first holding arms 10a and 10b, and the description thereof will be omitted.

次に、前記上開閉円板体（上カム）２７に形成の凹凸１００ａに基づく振動とは異なり、製品の充填（４）と製品の押込み（５）を実施する位置に停止したときに与える、上開閉円板体（上カム）２７の縁部に設置の振動体５５について図３を参照して説明する。
振動装置５０は、図３（Ａ）の断面図と（Ｂ）の正面図に示すように、上開閉円板体（上カム）２７には支持体（図示略）を介して振動モータ５１が取りつけてある。この振動モータ５１の駆動軸５１ａには、例えば、２ｍｍ偏心の偏心ピン５３が取りつけてある。そして、この偏心ピン５３には、往復動可能なＳ字状の振動体５５が、正面視、Ｕ字状のガイド体５４と摺動可能に、前記上開閉円板体（上カム）２７の製品の充填（４）と製品の押込み（５）において停止する位置に取り付けてある。
従って、製品の充填（４）において、振動モータ５１を起動すると、振動体５５を介して開閉ローラ２４は２ｍｍの往復動をする。そして、その開閉ローラ２４の往復動によって開閉レバー２３が揺動して、第１挟持腕１０ａ、１０ｂの挟持角を変更することによって、包装袋の側部を挟持している挟持爪１５ｂを介して包装袋を振動させる。 Next, unlike the vibration based on the unevenness 100a formed on the upper open / close disc body (upper cam) 27, it is given when stopped at a position where product filling (4) and product pushing (5) are performed. The vibrating body 55 installed at the edge of the upper opening / closing disc body (upper cam) 27 will be described with reference to FIG.
As shown in a sectional view of FIG. 3A and a front view of FIG. It is attached. For example, an eccentric pin 53 having an eccentricity of 2 mm is attached to the drive shaft 51 a of the vibration motor 51. The eccentric pin 53 has an S-shaped vibrating body 55 that can reciprocate so as to be slidable with a U-shaped guide body 54 in a front view. It is attached at a position where it stops in product filling (4) and product pushing (5).
Accordingly, when the vibration motor 51 is started in the product filling (4), the opening / closing roller 24 reciprocates by 2 mm via the vibration body 55. The opening / closing lever 23 swings by the reciprocating movement of the opening / closing roller 24 and changes the holding angle of the first holding arms 10a, 10b, thereby holding the side portion of the packaging bag via the holding claws 15b. Vibrate the packaging bag.

又、開閉円板体（下カム）（なお、この実施例では下開閉円板体）２７ａの縁部には、第２挟持腕１１ａ、１１ｂの挟持角を微変更する振動装置の振動体５５ａの端部が設けてあり、図４に示す。
この下開閉円板体（下カム）２７ａの縁部に設置してある振動体５５ａは、前記上開閉円板体（上カム）２７に設置の振動体５５と同じ機構である。
上開閉円板体（上カム）２７には支持体４９を介して振動モータ５１が取りつけてあり、この振動モータ５１の駆動軸５１ａには、例えば、２ｍｍ偏心の偏心ピン５３が取りつけてある。そして、この偏心ピン５３には、往復動可能なＳ字状の振動体５５ａが、正面視、Ｕ字状のガイド体５４と摺動可能に、前記下開閉円板体（下カム）２７ａの製品の充填（４）と製品の押込み（５）において停止する位置に取り付けてある。
従って、振動モータ５１を起動すると、振動体５５ａを介して開閉ローラ２４は２ｍｍの往復動をし、開閉ローラ２４によって開閉レバー２３を揺動して、第２挟持腕１１ａ、１１ｂの挟持角を変更することによって、包装袋の側部を挟持している挟持爪１５ｂを介して包装袋を振動させる。 In addition, at the edge of the opening / closing disk (lower cam) (in this embodiment, the lower opening / closing disk) 27a, the vibrating body 55a of the vibration device for finely changing the holding angle of the second holding arms 11a, 11b. Are provided, as shown in FIG.
The vibrating body 55 a installed at the edge of the lower opening / closing disc body (lower cam) 27 a has the same mechanism as the vibrating body 55 installed on the upper opening / closing disc body (upper cam) 27.
A vibration motor 51 is attached to the upper opening / closing disc body (upper cam) 27 via a support body 49, and an eccentric pin 53 of 2 mm eccentricity is attached to a drive shaft 51 a of the vibration motor 51, for example. The eccentric pin 53 has an S-shaped vibrating body 55a that can reciprocate so as to be slidable with the U-shaped guide body 54 in a front view. It is attached at a position where it stops in product filling (4) and product pushing (5).
Therefore, when the vibration motor 51 is started, the opening / closing roller 24 reciprocates by 2 mm through the vibrating body 55a, and the opening / closing lever 23 is swung by the opening / closing roller 24 so that the holding angle of the second holding arms 11a, 11b is increased. By changing, the packaging bag is vibrated via the clamping claws 15b that clamp the side portions of the packaging bag.

次に、前記ロータリー式包装機の製品の充填（４）、製品の押込み（５）における前記振動装置５０の作用について、図５を参照して説明する。
第１挟持腕１０ａ、１０ｂと第２挟持腕１１ａ、１１ｂが、製品の充填（４）に到って停止すると、先ず、製品収納用の漏斗８０が開口の包装袋内に降下して、製品（例えば、お茶等）を投下する。この製品を投下中において、振動装置５０の振動モータ５１を起動して、２ｍｍ偏心の偏心ピン５３を介して振動体５５、５５ａを２ｍｍ幅で往復動させる。この振動体５５、５５ａの往復動は、開閉ローラ２４を介して、開閉レバー２３が左挟持軸１６ａで揺動し、この開閉レバー２３の揺動によって、第１挟持腕１０ａ、１０ｂと第２挟持腕１１ａ、１１ｂは、それぞれの挟持角を変更して、包装袋の側部を挟持している挟持爪１５ｂを介して包装袋を振動させるので、製品は包装袋に良好に詰められる。尚、この振動は製品の充填が終了するまで実施される。 Next, the action of the vibration device 50 in the product filling (4) and product pushing (5) of the rotary packaging machine will be described with reference to FIG.
When the first clamping arms 10a and 10b and the second clamping arms 11a and 11b reach the product filling (4) and stop, first, the product storage funnel 80 descends into the open packaging bag, and the product (For example, tea). While the product is being dropped, the vibration motor 51 of the vibration device 50 is activated to reciprocate the vibrators 55 and 55a with a width of 2 mm via the eccentric pin 53 having an eccentricity of 2 mm.
