Description

【考案の詳細な説明】本考案は、梱包機においてバンドの接着切断が
完了した後に梱包物の取出しを容易にするために
バンド溝上から退避するシーラーテーブルの駆動
装置の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a driving device for a sealer table that is retracted from a band groove in order to facilitate removal of a packaged item after the band has been bonded and cut in a packaging machine.

（考案の技術的背景とその問題点）ハンドシール作業はシーラーテーブル下面にお
いて行われ、このシール作業終了後、シーラーテ
ーブルはバンド側方（機体の後方）へ退避動作さ
れる。(Technical background of the invention and its problems) The hand sealing operation is performed on the underside of the sealer table, and after the sealing operation is completed, the sealer table is retracted to the side of the band (to the rear of the machine).

この為の駆動装置として従来は第１図のように

多くしかも調整も容易でない欠点がある。 Conventionally, as a drive device for this purpose, as shown in FIG. 1, a mechanism has been used in which an arm shaft 21 is provided directly below the cam shaft and in parallel with the cam shaft. This mechanism has the disadvantage that it requires extra space in the height direction, has a large number of other parts, and is not easy to adjust.

I'm wearing it. Reference numeral 8 denotes a sealer table whose bottom surface 8a is formed in a plane parallel to the arrangement band and is positioned perpendicular to a vertical line (X-X') passing through the center of the cam shaft 7.
Reference numeral 9 designates a table arm, the base portion 9a of which is rotatably mounted on the camshaft 7 via a bush 10. 11 is a return spring; 12 is a stopper for regulating the retracted position of the table arm 9;
3 is a cam follower, which is pivotally supported by a lever 15 which is pivotally attached 14 to the table arm 9. 16
