Abstract

[Problem] Impulse heat sealers that seal bags made of polyester or the like have heretofore required a heater wire expansion/contraction absorption device or release film fixing device and a heavy transformer. Inventors have made heater wires into a zig-zag shape to eliminate these requirements. However, there is a need for sealers that are for infrequent household use, that break down less often, and that are more convenient and inexpensive. [Solution] To eliminate a power switch and timer from a circuit, and bring a plug and power strip into contact to shorten the duration of passage of current. This feature notwithstanding, when a current limiting element such as a PTC thermistor or the like is included in the circuit and a hand is released from the plug, safety is maintained by the other hand being kept away and passage of current being eliminated due to an elastic body provided around the plug.

Description

タイマーの無いインパルスシーラーImpulse sealer without timer
　インパルスヒートシーラーに関するもので、特にタイマー回路の無いシーラーに関する。 It is related to the impulse heat sealer, especially the sealer without a timer circuit.
　ポリエチレン等の袋を密封するインパルスヒートシーラーは、従来はヒーター線がリボン線で、加熱の度に伸縮する動作に対応した伸縮吸収装置や、その伸縮動作に引っ張られないための粘着層の無い離型膜を固定する装置といった複雑な構造と、電気回路でも重いトランスが必要で、スイッチやタイマーの接点にもトランスの誘導負荷が掛かり、接断時のスパークも大きいので、容量、規格とも通常の２～３倍と大きく、従って価格も高かった In the impulse heat sealer that seals a bag of polyethylene or the like, the heater wire is a ribbon wire in the past, and there is no expansion / contraction absorption device that can expand and contract each time it is heated, and there is no adhesive layer to prevent it from being pulled by the expansion and contraction operation. A complicated structure such as a device for fixing the mold film, a heavy transformer is required even in an electric circuit, an inductive load of the transformer is applied to the contacts of switches and timers, and the spark at the time of connection and disconnection is large, so both capacity and standard are normal. It was 2-3 times larger, so the price was high.
　そこで発明者らはジグザグ状のヒーター線を発明し、今までの伸縮吸収装置、離型膜固定装置を不要にして構造を簡単にし、電源回路から重いトランスを無くした。そしてプレス機構が常時閉のクリップ型シーラーを開発し、製品化した。そのシーラーは軽量で、中空でも使用出来るので、小事業用や農業用としての利用が増加していった。 Therefore, the inventors invented a zigzag-shaped heater wire, eliminating the need for the conventional expansion / contraction absorbing device and the release membrane fixing device, simplifying the structure, and eliminating the heavy transformer from the power supply circuit. Then, the press mechanism developed and commercialized a clip-type sealer that is always closed. The sealer is lightweight and can be used in the air, so its use for small businesses and agriculture has increased.
　しかしその本発明者らのインパルスシーラーでさえ、電源回路にはタイマーが必須であると思い込んでいた。タイマーが必要な理由はヒートシーラーが生産財であり、袋等を効率よく生産し、しかも不良品の発生を防ぐためであった。 However, even the impulse sealers of the present inventors assumed that a timer was indispensable for the power supply circuit. The reason why the timer is necessary is that the heat sealer is a production product, and it efficiently produces bags and the like, and also prevents the occurrence of defective products.
　生産財であるシーラーは連続使用が当然で、そうなると余分の熱量は蓄積し、冷却時間が長くなる。だから効率を上げるには必要最小限の加熱時間の設定が必要であった。そしてその多数の加工品の中で一つでも加熱時間が短く、その結果シール不良が混じれば、納品後に全て返品ということもあるので、タイマーは正確、確実でなければならなかった。 It is natural that the sealer, which is a production product, is used continuously, and if that happens, excess heat will be accumulated and the cooling time will be longer. Therefore, it was necessary to set the minimum required heating time to improve efficiency. And even one of the many processed products has a short heating time, and as a result, if a seal defect is mixed, all of them may be returned after delivery, so the timer had to be accurate and reliable.
　さらに生産財であるインパルスシーラーは、クリップ型シーラーを除いて、全てプレス機構が常時開いている状態で、使用時のみ閉じた状態となるものであった。その理由は万一そのプレス機構が開いている時にヒーター線が発熱すると、ヒーター線は空気で囲まれた状態なので「空焚き」状態になり、1秒もすれば４００～６００℃にも達し、周囲の材料を燃やしてしまうことになる。従ってプレス機構が閉じると同時にヒーター電源とタイマーが入り、予定時間経過後にヒーター電源が切れる構造であった。 Furthermore, the impulse sealers, which are production goods, were all in a state where the press mechanism was always open and closed only when in use, except for the clip type sealer. The reason is that if the heater wire heats up while the press mechanism is open, the heater wire will be surrounded by air, so it will be in an "empty heating" state, reaching 400-600 ° C in 1 second. It will burn the surrounding materials. Therefore, the structure was such that the heater power and timer were turned on at the same time as the press mechanism was closed, and the heater power was turned off after the scheduled time had elapsed.
　タイマーやスイッチが無い電熱器具としては、熱板式ヒートシーラーや半田鏝や電気あんかがある。しかしそれらは通電開始から３分位経過すると発熱と放熱の平衡が取れて、温度が一定になり、熱的に安定しているもので、使い方もそれらのプラグを電源のコンセントに差し込んだまま半日とか一晩そのままにするものであった。 Electric heating appliances without timers and switches include hot plate type heat sealers, soldering irons, and electric heaters. However, about 3 minutes after the start of energization, heat generation and heat dissipation are balanced, the temperature becomes constant, and they are thermally stable. Or something that was left overnight.
　近年ハンダ鏝を素早く加熱しようと、ボタンを押して別のヒーターを加熱する、言わばブースターのような回路や、本発明者が発明した特許文献３のハンダ鏝のように、熱伝導の高い窒化アルミを使った速熱式のもので、電源スイッチを例えば1秒押すごとに３０℃上昇する構造のものも出て来た。しかしハンダ鏝は鏝先の加熱状態をハンダの溶け具合で実際に見ながら発熱を調節し、作業時間も１０～２０秒と掛かるもので、インパルスシーラーのプレス下の１～２秒の一回限りの加熱方法とは、とても同一に考えられるものではなかった。 In recent years, in order to quickly heat a soldering iron, a circuit like a booster that heats another heater by pressing a button, or aluminum nitride with high thermal conductivity like the soldering iron of Patent Document 3 invented by the present inventor is used. Some of the fast-heating type ones used have a structure that raises the temperature by 30 ° C every time the power switch is pressed for one second, for example. However, the soldering iron adjusts the heat generation while actually observing the heating state of the iron tip by the melting condition of the solder, and the working time is 10 to 20 seconds, so it is only once for 1 to 2 seconds under the press of the impulse sealer. The heating method of was not considered to be very the same.
　一方で家庭には特に色々な袋が入ってくるので、厳密に言えば袋の厚さに応じてタイマーを調節する必要があった。しかしタイマーを一々調節するのは面倒であったし、茶袋やレトルト袋等のようにタイマーを限度いっぱいに調節しても加熱が不足したり、表面の素材が焦げたりするので、両面シーラーのような専用機が必要な袋もあった。 On the other hand, various bags come into the home, so strictly speaking, it was necessary to adjust the timer according to the thickness of the bag. However, it was troublesome to adjust the timer one by one, and even if the timer was adjusted to the maximum limit like a tea bag or a retort bag, the heating would be insufficient and the surface material would be burnt, so it looks like a double-sided sealer. Some bags required a special machine.

　使用回数が１日に数回といった家庭用や簡単な業務用ではシーラーの価格が高かった。また家庭用では使用回数が少なく消耗しないので、ヒーター線が切れるまで１５年以上も使い続けられるが、そうなるとタイマーを構成する電子部品や、スイッチ、電源コードに故障や経年変化を起こすものが出て来た。 The price of the sealer was high for home use and simple business use, such as using it several times a day. In addition, since it is used less frequently for home use and does not wear out, it can be used for more than 15 years until the heater wire is cut off. I came.
　従って安価で、長年使用しても故障が無く、しかも家庭に入ってくる袋は全てシール出来るシーラーが欲しかった。 Therefore, I wanted a sealer that was cheap, had no trouble even after many years of use, and could seal all the bags that came into my home.
　生産財としてのシーラーをやめた。つまりシール時間を２～３倍にしても、冷却時間を充分に取れば、シール出来る事実を踏まえて、家庭用としてプラグとテーブルタップとを見当で２～３秒接触させることで、電源スイッチとタイマー回路を無くした。 The sealer as a production product was stopped. In other words, even if the sealing time is doubled or tripled, if the cooling time is sufficient, it can be sealed. I lost the timer circuit.
　その接触時間が長すぎる場合の危険を回避するために、回路にＰＴＣサーミスタや電流ヒューズ等の電流制限素子を入れた。又プラグから手を離すと、どちらかに設けられた弾性体により、相手から離れて通電しなくなる工夫もした。 In order to avoid the danger when the contact time is too long, a current limiting element such as a PTC thermistor or a current fuse was inserted in the circuit. Also, when you take your hand off the plug, the elastic body provided on either side separates you from the other and stops energizing.
　タイマーが無くても、見当で２～３秒通電し、良いシールが出来た。さらに部品が少なくなった分、故障や経年変化が少なくなり、長持ちするようになった。 Even if there was no timer, it was energized for 2 to 3 seconds, and a good seal was made. Furthermore, as the number of parts is reduced, breakdowns and secular variation are reduced, and the product lasts longer.
　タイマーという言わば枠が無くなったので、自在に加熱時間を調節でき、通常は専用機を使う茶入れの紙袋や、アルミの厚いレトルト袋のシールも可能になった。 Since the frame of the timer has disappeared, the heating time can be adjusted freely, and it has become possible to seal a paper bag for a tea bowl or a thick aluminum retort bag, which normally uses a dedicated machine.
車用クリップ型シーラーの斜視図である。It is a perspective view of the clip type sealer for a car. 図１の回路図である。It is a circuit diagram of FIG. １００Ｖ用プラグの側面図である。It is a side view of the plug for 100V.
　実施例１では図1～図２で車用としてプレス機構が常時閉じているクリップ型シーラーに応用したものを、図３で１００Ｖ用のプラグを説明する。 In Example 1, FIGS. 1 to 2 are applied to a clip-type sealer in which the press mechanism is always closed for a car, and FIG. 3 describes a plug for 100 V.
　図１は車用の、クリップ又は洗濯ばさみのような形状をしたクリップ型シーラー１の斜視図で、図２はその回路図である。シーラー本体１は例えばポリカーボネート製で、ヒーターを内蔵している上部開口部２と、シリコンゴムを内蔵した下部開口部３と、輪の形をしたバネ４でプレス機構を構成する。そのバネ４がプレス機構を常時閉じているが、蝶番５の先の持ち手６，６を握ると開口するので、（図は無いが）袋を挟む。 FIG. 1 is a perspective view of a clip-type sealer 1 for a car, which is shaped like a clip or a clothespin, and FIG. 2 is a circuit diagram thereof. The sealer body 1 is made of, for example, polycarbonate, and the press mechanism is composed of an upper opening 2 having a built-in heater, a lower opening 3 having a built-in silicon rubber, and a ring-shaped spring 4. The spring 4 always closes the press mechanism, but it opens when the handles 6 and 6 at the tip of the hinge 5 are gripped, so the bag is sandwiched (not shown).
　持ち手６の内側からコード７とその先に電源プラグ８が出ていて、先端にプラス極９と、側面にマイナス極１０が有り、その近くにシリコンスポンジの突起１１が備わっている。そのプラグ８を車のシガーソケット（図は無い）に入れ、押し付けると、両極が接触し、電流が流れる。そして力を抜くと、そのスポンジの突起１１が反発して電流が止まり、袋のシールは終わる。 The cord 7 and the power plug 8 are protruding from the inside of the handle 6, the positive pole 9 is at the tip, the negative pole 10 is at the side, and the protrusion 11 of the silicon sponge is provided near it. When the plug 8 is inserted into a car cigarette lighter socket (not shown) and pressed, the two poles come into contact with each other and an electric current flows. Then, when the force is released, the protrusion 11 of the sponge repels and the current stops, and the sealing of the bag ends.
　図２はその回路図で、ヒーター１２と電流制限素子としてＰＴＣサーミスタ１３が直列に結線されている。このヒーター１２は鉄合金の抵抗線で幅２ｍｍ、長さは１２ｃｍで、２ｍｍピッチで左右交互に１ｍｍのスリットを入れている。これにより抵抗値が約３．５Ωになるので、１２Ｖでは３．５Ａ流れ、４０Ｗとなる。このシーラー１では通常３～５秒でシールは出来る。 FIG. 2 is a circuit diagram thereof, in which the heater 12 and the PTC thermistor 13 as a current limiting element are connected in series. The heater 12 is an iron alloy resistance wire having a width of 2 mm and a length of 12 cm, and has slits of 1 mm alternately on the left and right at a pitch of 2 mm. As a result, the resistance value becomes about 3.5Ω, so that 3.5A flows at 12V and becomes 40W. With this sealer 1, the seal can usually be done in 3 to 5 seconds.
　ＰＴＣサーミスタ１３は、一例をあげると、７～８秒で１２０℃になり、内部抵抗が急激に増大し、全体の電流が減少し、その温度が下がるまで、ヒーター１２の発熱は抑えられる。従って無駄にと言うか、このシーラー１のシール時間が長すぎた場合の安全弁として、このＰＴＣサーミスタ１３は働く。この発熱までの温度や時間は、選ぶサーミスタにより異なるので、あたかもタイマーのように機能するものや、もっぱら安全弁となるものもある。 For example, the PTC thermistor 13 reaches 120 ° C. in 7 to 8 seconds, the internal resistance rapidly increases, the overall current decreases, and the heat generation of the heater 12 is suppressed until the temperature drops. Therefore, this PTC thermistor 13 works as a safety valve when the sealing time of the sealer 1 is too long. The temperature and time until this heat generation varies depending on the thermistor selected, so some of them function as if they were timers, while others are exclusively safety valves.
[規則91に基づく訂正 22.12.2020]　
　同様に電流制限素子としてＰＴＣサーミスタ１３の代わりに、又は同時に電流ヒューズを入れることも出来る。電流ヒューズは規定の３．５Ａの電流を１分間流すと溶断する。このインパルスシーラーはヒーター面積当たり、通常のシーラーの３分の１の発熱量なので、通電１分後くらいでシリコンゴムが燃え出し、煙が出始める。従って全体が燃え出す前にヒューズが機能すると言える。ヒューズ規格を小さいものにすれば煙の出る前に切ることも出来る。[Correction under Rule 91 22.12.2020]
Similarly, a current fuse can be inserted in place of or at the same time as the PTC thermistor 13 as a current limiting element. The current fuse blows when a specified current of 3.5 A is passed for 1 minute. Since this impulse sealer generates one-third of the heat generated by a normal sealer per heater area, the silicone rubber burns out and smoke begins to be emitted about 1 minute after energization. Therefore, it can be said that the fuse works before the whole burns out. If the fuse standard is made smaller, it can be blown before smoke comes out.
　図３に１００Ｖ用プラグ１４を示す。このプラグ１４には弾性力のあるプラスチック製のスプリング１５を巻き付けている。これによりこのプラグ１４を外部電源とつながっているコンセント又はテーブルタップ（図は無い）に接触させようとするとき、深くは刺さらず、さらに差し込む力を抜けば、プラグ１４はコンセントから抜ける。 FIG. 3 shows the plug 14 for 100V. An elastic plastic spring 15 is wound around the plug 14. As a result, when trying to bring the plug 14 into contact with an outlet or a table tap (not shown) connected to an external power source, the plug 14 does not pierce deeply, and if the plugging force is released, the plug 14 is removed from the outlet.
　この使用後に、プラグが電源から外れるというメリットは、この使用時間の少ないインパルスシーラーの安全性には非常に有効である。電源に接続されている限りそのシーラーは、コードが経年劣化でショートする、回路の不良導通で異常加熱する、地震で倒壊した後の電源回復での火災の発生等の危険が付きまとう。 The merit that the plug is disconnected from the power supply after this use is very effective for the safety of this impulse sealer with a short usage time. As long as it is connected to a power source, the sealer carries the risk of a short circuit due to aging, abnormal heating due to defective continuity of the circuit, and a fire when the power source is restored after it collapses due to an earthquake.
　電源スイッチがなまじ有ると、プラグをコンセントにつないで使用した後、そのまま抜くことを忘れることが多い。従ってタイマーと同時に電源スイッチを回路から除き、使用の度にプラグ又はコネクターが外れるならば、前述のリスクは皆無である。 If there is a power switch, it is often forgotten to unplug it after connecting it to an outlet. Therefore, if the power switch is removed from the circuit at the same time as the timer and the plug or connector is disconnected each time it is used, there is no risk described above.
　誤って長く電源を接続した場合は、１００Ｖ用の標準的な２０ｃｍ、２００Ｗのシーラーは１０秒後くらいで煙が出初めるので、気が付く筈で、通電を止めることが出来る。その場合、最初に出る煙はフッ素樹脂テープのシリコン系粘着剤なので、シーラーとして機能に影響は無いのでそのまま使い続けられるし、フッ素樹脂テープを張り替えればもとに戻る。なお通電を示すランプは無いものとして説明しているが、有れば通電の目安が付きやすい。 If you accidentally connect the power supply for a long time, the standard 20cm, 200W sealer for 100V will start to emit smoke in about 10 seconds, so you should be aware that you can turn off the power. In that case, the smoke that comes out first is a silicone-based adhesive for fluororesin tape, so it does not affect the function as a sealer, so you can continue to use it as it is, and if you replace the fluororesin tape, it will return to its original state. It is explained that there is no lamp that indicates energization, but if there is, it is easy to get a guideline for energization.
　タイマー無しのシーラーに慣れてくると、今まで専用機でしか出来なかった袋のシールも出来るようになる。本来タイマーはヒーターの加熱の限界を、安全度を見て制限しているし、タイムアップして復元するまで多少時間が掛かる。しかし本発明のシーラーならば袋を見て自在に加熱が出来るので、家庭に入ってくるほぼ全ての袋がシール可能になった。 As you get used to the sealer without a timer, you will be able to seal bags that you could only do with a dedicated machine. Originally, the timer limits the heating limit of the heater by looking at the safety level, and it takes some time to restore the time. However, since the sealer of the present invention can be heated freely by looking at the bag, almost all the bags entering the home can be sealed.
　例えば紙袋は、その表面が紙と言う断熱材なので、一回のシールで済まそうとすると高温になり、紙の表面が焦げる。だから低温で複数回シールをすると、紙の表面を焦がすことなく充分な熱が境界面まで達する。 For example, the surface of a paper bag is a heat insulating material called paper, so if you try to seal it once, it will become hot and the surface of the paper will be scorched. So if you seal multiple times at low temperature, enough heat will reach the interface without burning the surface of the paper.
　通常両面ヒーターのシーラーが必要なアルミのレトルト袋は、高温で限界まで、つまり煙が出始める前後までの加熱を複数回すると、片側からの加熱でもしっかりとしたシールが出来るようになった。 Aluminum retort pouches, which normally require a double-sided heater sealer, can be sealed firmly even when heated from one side by heating multiple times until the temperature reaches the limit, that is, before and after smoke begins to come out.
　本発明のインパルスヒートシーラーは生産財とは見なされないが、きれいで丈夫なシールが出来た。器具の耐久性にも問題が無い。 The impulse heat sealer of the present invention is not considered to be a product, but a clean and durable seal was made. There is no problem with the durability of the equipment.
　慣れてくると、家庭に入ってくるほぼ全ての袋がシール可能になった。 As I got used to it, almost all the bags that came into my home could be sealed.
　タイマー回路や電源スイッチが無いということは、製作も容易で、それらの故障も発生しない。 The absence of a timer circuit and power switch makes it easy to manufacture and does not cause any failures.
　安価に供給出来るので、家庭用シーラーとして非常に普及しやすい。それにより食料や買ってきた袋詰めの生活用品の保存に貢献し、ロスが少なくなり、エコ生活に大きく貢献する。 Because it can be supplied at low cost, it is very easy to spread as a household sealer. As a result, it contributes to the preservation of food and the bags of daily necessities that have been bought, reduces losses, and greatly contributes to eco-friendly living.
