【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、ワークの包装・梱包等に用いる脱気ノズル
付ヒートシール装置の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an improvement in a heat seal device with a degassing nozzle used for packaging and packing a work.
従来の熱融着性樹脂フィルムをラミネートしたアルミ
箔等から成る袋に被包装物として例えばワーク(以下、
ワークという)を収納し、袋内の空気を抜いて真空に近
い状態にして、袋の入口を加熱封止するのに、第2図に
示すような脱気ノズル付ヒートシール装置が用いられて
いる。For example, a work (hereinafter, referred to as a work) is to be packaged in a bag made of aluminum foil or the like laminated with a conventional heat-fusible resin film.
A heat-sealing device with a deaeration nozzle as shown in FIG. 2 is used to store the work, draw air in the bag, make the bag nearly vacuum, and heat seal the bag inlet. I have.
上記従来装置は、開閉自在になした2本の平行なヒー

ブルリフタ(14)とエアシリンダ(10)とで以て、テー
ブルリフタ(14)上に載置する袋内のワークと、エアシ
リンダ(10)のロッド(10a)にブラケット(11)を介
して設けた脱気ノズル(12)とを、接近離隔可能にして
成る。The above-mentioned conventional apparatus has two parallel heaters (13) (13) which can be freely opened and closed, and a table lifter (14)
, An air cylinder (10) is disposed above, and the work in the bag to be placed on the table lifter (14) and the air cylinder by the table lifter (14) and the air cylinder (10). The degassing nozzle (12) provided on the rod (10a) of (10) via the bracket (11) can be approached and separated.
そして、従来装置はワークを収納した袋の入口を次の
ように加熱封止していた。The conventional apparatus heats and seals the entrance of the bag storing the work as follows.
即ち、ワーク(W)を収納した袋(E)をテーブルリ
フタ(14)上に載置する。そして、テーブルリフタ(1
4)を上昇し、袋(E)の入口部分(Ea)を2本のヒー
タ(13)(13)間に位置したところで停止する。That is, the bag (E) containing the work (W) is placed on the table lifter (14). And the table lifter (1
4) is lifted, and stopped when the entrance portion (Ea) of the bag (E) is located between the two heaters (13) (13).
次に、エアシリンダ(10)を作動して真空ポンプ(図

(Ea)を挾み込む。その後、テーブルリフタ(14)を更
に上昇して脱気ノズル(12)の先端とワーク(W)とが
僅かに接触したところで停止する。Next, the air cylinder (10) is operated to lower the deaeration nozzle (12) connected to a vacuum pump (not shown), and the tip of the nozzle is inserted into the inlet portion (Ea) of the bag. The two heaters are closed, and the inlet portion (Ea) of the bag is sandwiched between the heaters (13) and (13). Thereafter, the table lifter (14) is further raised and stopped when the tip of the degassing nozzle (12) and the work (W) slightly contact each other.
そして、真空ポンプを作動して袋(E)内の空気を抜
いた後、エアシリンダ(10)で以て脱気ノズル(12)を
上昇して袋内より引き抜くと同時に、ヒータ(13)(1
3)に所定時間通電して袋の入口部分(Ea)を加熱封止
する。Then, after the air in the bag (E) is evacuated by operating the vacuum pump, the deaeration nozzle (12) is raised by the air cylinder (10) and pulled out from the bag, and at the same time, the heater (13) ( 1
Power is supplied for a predetermined time to 3) to heat seal the inlet portion (Ea) of the bag.
よって、ヒータ(13)(13)を開いて、テーブルリフ
タ(14)を下降してワークの包装が完了する。Therefore, the heaters (13) and (13) are opened, the table lifter (14) is lowered, and the packaging of the work is completed.
しかし、上記従来技術では、脱気ノズルを下降すると
きや、テーブルリフタを2度目に上昇するときに、停止
位置の誤動作により脱気ノズルとワークとの衝突によっ
て脱気ノズルが曲折して、脱気不可能になることがあっ
た。However, in the above-described conventional technology, when the deaeration nozzle descends or when the table lifter is raised for the second time, the deaeration nozzle is bent by collision of the deaeration nozzle with the work due to a malfunction of the stop position, and the deaeration nozzle is deflected. Sometimes I became impatient.
本発明は、上記従来技術の課題に鑑みてなしたもの
で、その目的とするところは、脱気ノズルとワークとの
衝突による脱気ノズルの損傷を防止して、脱気不可能の
状態が生ずることなく、包装袋を加熱封止可能にした脱
気ノズル付ヒートシート装置を提供するにある。The present invention has been made in view of the above-described problems of the related art, and an object of the present invention is to prevent the deaeration nozzle from being damaged due to collision between the deaeration nozzle and the work so that the deaeration cannot be performed. It is an object of the present invention to provide a heat sheet device with a degassing nozzle which can heat seal a packaging bag without causing any problem.
上記目的を達成するために、本発明の脱気ノズル付ヒ

を停止可能にして成る。In order to achieve the above object, a heat sealing device with a deaeration nozzle according to the present invention includes a heater that can be freely opened and closed,
In a heat sheet device with a deaeration nozzle provided above and below the deaeration nozzle and a work for moving the deaeration nozzle closer to and away from the work, a sensor for detecting a collision between the nozzle and the work is provided for one of the above elevating means. A buffer mechanism for alleviating the collision is provided, and the approach operation of the lifting / lowering means can be stopped by the detection signal of the sensor.

と、緩衝機構によって衝突のエネルギーを吸収して衝撃
を緩和すると共に、センサで検出した衝突信号を昇降手
段に伝達して、昇降手段の接近動作を停止させる。When the heat sealing device with the degassing nozzle configured as described above is operated and the degassing nozzle collides with the workpiece in the bag, the shock absorbing mechanism absorbs the energy of the collision to mitigate the impact, and is detected by the sensor. The generated collision signal is transmitted to the elevating means, and the approaching operation of the elevating means is stopped.
