The separator switching means is constituted by the rotating member 13 and the driving means.

次に、シールアンドカット装置１の動作について説明する。
シールアンドカット装置１の超音波ホーン１１と受け部材９は、後述するように往復動作して、往動作と復動作のそれぞれにおいて包装材Ｓに対してシールアンドカットを行う。
図２に示すように右側のセパレータ部材１５は突出姿勢となっており、左側のセパレータ部材１６は退避姿勢となっている。
上記突出姿勢とは、後述するように移動時に超音波ホーン１１と受け部材９によってシールアンドカットされた部位を通過する姿勢である。また、上記退避姿勢とは、後述するように移動時に超音波ホーン１１と受け部材９によってシールアンドカットされる部位から離れた位置を通過する姿勢である。 Next, the operation of the seal and cut device 1 will be described.
The ultrasonic horn 11 and the receiving member 9 of the seal and cut device 1 reciprocate as will be described later, and perform seal and cut on the packaging material S in each of the forward operation and the backward operation.
As shown in FIG. 2, the right separator member 15 is in a protruding posture, and the left separator member 16 is in a retracted posture.
The protruding posture is a posture that passes through a portion sealed and cut by the ultrasonic horn 11 and the receiving member 9 during movement, as will be described later. Further, the retracted posture is a posture that passes through a position away from a portion that is sealed and cut by the ultrasonic horn 11 and the receiving member 9 during movement, as will be described later.

超音波ホーン１１と受け部材９の往動作では、超音波ホーン１１と受け部材９は左方向（図２において矢印の示す方向）へ移動しながら、超音波ホーン１１と受け部材９との対向領域において包装材Ｓに対してシールアンドカットを行う。この際、シールアンドカットを行ったにもかかわらず切断不良による未切断部分が発生することがあるが、この場合であっても右側のセパレータ部材１５は超音波ホーン１１と受け部材９に追動し、未切断部分に当たって、この未切断部分を完全に切り離しながらシールアンドカットされた部位を通過する。そしてセパレータ部材１５が包装材Ｓからある程度離れたところで超音波ホーン１１と受け部材９が停止して、往動作が終了する。   In the forward movement of the ultrasonic horn 11 and the receiving member 9, the ultrasonic horn 11 and the receiving member 9 move in the left direction (the direction indicated by the arrow in FIG. 2), and the opposing region between the ultrasonic horn 11 and the receiving member 9. Then, the packaging material S is sealed and cut. At this time, an uncut portion due to cutting failure may occur despite the seal and cut being performed. Even in this case, the right separator member 15 is driven by the ultrasonic horn 11 and the receiving member 9. Then, it hits the uncut portion and passes through the sealed and cut portion while completely cutting off the uncut portion. Then, when the separator member 15 is separated from the packaging material S to some extent, the ultrasonic horn 11 and the receiving member 9 are stopped, and the forward operation is finished.

なお、左側のセパレータ部材１６は超音波ホーン１１と受け部材９によってシールアンドカットされる部位から離れた位置を通過する。従って、超音波ホーン１１と受け部材９によってシールアンドカットを行う際に、セパレータ部材１６がシールアンドカットされる部位に当たって邪魔になるのを防止できる。   The left separator member 16 passes through a position away from the portion to be sealed and cut by the ultrasonic horn 11 and the receiving member 9. Therefore, when the sealing and cutting is performed by the ultrasonic horn 11 and the receiving member 9, it is possible to prevent the separator member 16 from striking the portion to be sealed and cut.

上記往動作が終了した後、エアシリンダ２３の出入軸２５が前進し、出入軸２５に設けられた連係ピン２７が連係部材１７を前方向へ押し、連係部材１７と共に回動部材１３が図２において時計回りの方向へ回動させられる。即ち、出入軸２５、連係ピン２７及び連係部材１７は回動部材１３を図２において時計回りの方向へ回動させ、図３に示すように左側のセパレータ部材１６を突出姿勢とし、右側のセパレータ部材１５を退避姿勢とする。   After the forward movement is completed, the loading / unloading shaft 25 of the air cylinder 23 moves forward, the linking pin 27 provided on the loading / unloading shaft 25 pushes the linking member 17 forward, and the rotating member 13 together with the linking member 17 is shown in FIG. Is rotated in the clockwise direction. That is, the input / output shaft 25, the linking pin 27, and the linking member 17 rotate the rotating member 13 in the clockwise direction in FIG. The member 15 is in the retracted posture.

往動作終了後に包装材Ｓは下方向へ１ピッチ送られ、この包装材Ｓに茶葉類等が充填されてから、超音波ホーン１１と受け部材９の復動作が開始される。
超音波ホーン１１と受け部材９の復動作では、超音波ホーン１１と受け部材９は右方向（図３において矢印の示す方向）へ移動しながら、包装材Ｓに対してシールアンドカットを行う。この際にも切断不良による未切断部分が発生した場合には、上記したセパレータ部材１５と同様に左側のセパレータ部材１６は未切断部分に当たって、この未切断部分を完全に切り離しながらシールアンドカットされた部位を通過する。そしてセパレータ部材１６が包装材Ｓからある程度離れたところで超音波ホーン１１と受け部材９が停止して、復動作が終了する。
なお、右側のセパレータ部材１５は超音波ホーン１１と受け部材９によってシールアンドカットされる部位から離れた位置を通過する。 After the forward operation is finished, the packaging material S is fed downward by 1 pitch, and after the packaging material S is filled with tea leaves or the like, the return operation of the ultrasonic horn 11 and the receiving member 9 is started.
In the backward operation of the ultrasonic horn 11 and the receiving member 9, the ultrasonic horn 11 and the receiving member 9 perform sealing and cutting on the packaging material S while moving in the right direction (the direction indicated by the arrow in FIG. 3). Also in this case, when an uncut portion due to a cutting failure occurs, the left separator member 16 hits the uncut portion and is sealed and cut while completely separating the uncut portion, like the separator member 15 described above. Pass through the site. Then, when the separator member 16 is separated from the packaging material S to some extent, the ultrasonic horn 11 and the receiving member 9 are stopped, and the reverse operation is finished.
The right separator member 15 passes through a position away from the portion to be sealed and cut by the ultrasonic horn 11 and the receiving member 9.

上記復動作が終了した後、エアシリンダ２３の出入軸２５が後退し、連係ピン２７が連係部材１７を後方向へ押し、連係部材１７と共に回動部材１３が図３において反時計回りの方向へ回動させられる。即ち、出入軸２５、連係ピン２７及び連係部材１７は回動部材１３を図３において反時計回りの方向へ回動させ、図２に示すように右側のセパレータ部材１５を突出姿勢とし、左側のセパレータ部材１６を退避姿勢とする。そして包装材Ｓが下方向へ１ピッチ送られ、上記した超音波ホーン１１と受け部材９の往動作が開始される。   After the reverse operation is completed, the loading / unloading shaft 25 of the air cylinder 23 is retracted, the linkage pin 27 pushes the linkage member 17 backward, and the rotation member 13 together with the linkage member 17 moves counterclockwise in FIG. It can be rotated. That is, the input / output shaft 25, the linking pin 27, and the linking member 17 rotate the rotating member 13 in the counterclockwise direction in FIG. 3, and as shown in FIG. The separator member 16 is in the retracted posture. Then, the packaging material S is sent one pitch downward, and the forward movement of the ultrasonic horn 11 and the receiving member 9 is started.

前述したように切断不良による未切断部分が発生した場合であっても、セパレータ部材１５又はセパレータ部材１６が未切断部分を完全に切り離しながら包装材Ｓのシールアンドカットされた部位を通過するので、包装材Ｓを確実に分離することができる。   As described above, even when an uncut portion due to defective cutting occurs, the separator member 15 or the separator member 16 passes through the sealed and cut portion of the packaging material S while completely cutting the uncut portion. The packaging material S can be reliably separated.

以上、本発明の実施の形態について詳述してきたが、具体的構成は、この実施の形態に限られるものではなく、本発明の要旨を逸脱しない範囲における設計の変更などがあっても発明に含まれる。
上記実施の形態では、超音波ホーン１１と受け部材９を左右方向に移動させる構成としたが、超音波ホーン１１と受け部材９を、前後方向や上下方向等に移動させる構成としてもよい。
上記実施の形態では、シールアンドカット装置１をティーバッグ等の包装体を製造する製袋充填装置に搭載したが、シールアンドカット装置１を、例えば包装用の袋を製造する装置に搭載してもよい。 The embodiment of the present invention has been described in detail above. However, the specific configuration is not limited to this embodiment, and the present invention can be changed even if there is a design change without departing from the gist of the present invention. included.
In the above embodiment, the ultrasonic horn 11 and the receiving member 9 are moved in the left-right direction. However, the ultrasonic horn 11 and the receiving member 9 may be moved in the front-rear direction, the up-down direction, and the like.
In the above embodiment, the seal and cut device 1 is mounted on a bag making and filling device that manufactures a package such as a tea bag. However, the seal and cut device 1 is mounted on a device that manufactures a bag for packaging, for example. Also good.

本発明は、被シール材に対してシールアンドカットを行うシールアンドカット装置の製造業に利用可能である。   INDUSTRIAL APPLICABILITY The present invention can be used in the manufacturing industry of a seal and cut device that performs seal and cut on a material to be sealed.
