【発明の詳細な説明】 〔発明の目的〕 （産業上の利用分野） 本発明は、縦方向テープと横方向テープとから格子状を
なす樹脂製ウエブの製造装置に係り、特に両テープの交
差部分を熱融着する熱融着装置の改良に関する。DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to an apparatus for producing a resin-made web in a lattice shape from a vertical tape and a horizontal tape, and particularly to the intersection of both tapes. The present invention relates to an improvement in a heat-sealing device for heat-sealing parts.

ープ供給ヘッドを回転させ、円筒状の織物を造るタイプ
のものとがある。(Prior Art) Conventionally, in the case of producing a grid-like web, a method of weaving a finely slit resin tape on a loom is used. In the loom, there are two types of vertical tapes that are stretched on a plane, one type that allows the horizontal tapes to pass one by one using a shuttle in the right angle direction, and one type that has longitudinally arranged in a cylindrical shape. On the other hand, there is a type in which several lateral tape feeding heads are rotated at right angles to make a cylindrical woven fabric.

ープ群の間を、横方向に１本ずつ横方向テープを通す必
要があり、また円筒状に織上げるタイプの後者は、一度
に通す横方向テープの本数に限度があるため、いずれも
生産速度が遅いという問題がある。(Problems to be Solved by the Invention) In the conventional method for manufacturing a lattice-like web, the former type of weaving into a flat plate is one in the transverse direction between the longitudinal tape groups arranged in the longitudinal direction. It is necessary to pass the transverse tape, and the latter of the type of weaving in a cylindrical shape has a problem that the production speed is slow because there is a limit to the number of transverse tapes that can be passed at one time.

問題がある。Further, in any of the above types, since the tape is woven, there is a problem that the tape is likely to be twisted, unlike the case where the fiber is used. Also, if an attempt is made to provide a gap between the tapes, Since the intersecting portions are not fixed, the tapes in both directions are easily displaced, and there is a problem that it is impossible to manufacture a web having a constant gap between the tapes.

ープの製造装置が提案されている。Therefore, in some cases, a vertical tape group composed of a plurality of juxtaposed thermoplastic resin tapes and a lateral tape group composed of a plurality of juxtaposed thermoplastic resin tapes are arranged orthogonally on the table, and A lattice-shaped thermoplastic tape manufacturing apparatus has been proposed in which a tape group is pressed against a table by a heat-sealing device and the crossing portions of both tape groups are heat-sealed to manufacture a lattice-shaped web.

う問題がある。By the way, in this type of grid-shaped thermoplastic web manufacturing apparatus, if the heat-sealing device has a hot plate structure in which a heat source is attached to one metal plate, it is difficult to make the temperature of each part of the hot plate uniform. In addition, the heating plate may be turned over by heating and a perfect flat surface may not be obtained, so that a uniform pressing force may not be applied to both tape groups. In this case, there is a problem that the heat fusion force at the intersection of the two tape groups is not stable.

ことを目的とする。The present invention has been made in consideration of such a point, and it is possible to correct the warp of the hot plate generated by heating to make it a perfect flat surface and to make the surface temperature of the hot plate uniform. An object of the present invention is to provide an apparatus for producing a lattice-shaped plastic web that can be used.

するようにしたことを特徴とする。(Means for Solving the Problem) As a means for achieving the above-mentioned object, the present invention provides a heat fusion device, a hot plate for pressing both vertical and horizontal tape groups, and at least a peripheral portion and a center of the hot plate. A heat source capable of separately heating the heat plate, a temperature sensor capable of separately detecting at least the peripheral portion and the central portion of the hot plate, an upper plate located above the hot plate, the upper plate and the heat It is characterized in that a large number of push screws and pull screws for adjusting the flatness of the hot plate are arranged between the hot plate and the plate.
（作用） 本発明に係る格子状熱可塑性ウエブの製造装置において
は、熱融着装置の熱板が、熱源により加熱されるととも
に、その温度が温度センサにより検出される。(Operation) In the lattice-shaped thermoplastic web manufacturing apparatus according to the present invention, the hot plate of the heat fusion apparatus is heated by the heat source and the temperature thereof is detected by the temperature sensor.
ところで、熱板を加熱すると、一般的に周辺部は放熱に

っており、温度センサも、熱板の少なくとも周辺部と中
央部とを分けて検出可能となっている。そしてこれによ
り、熱板の温度を均一化することが可能となる。By the way, when the hot plate is heated, the temperature of the peripheral portion generally becomes lower than that of the central portion due to heat radiation. Therefore, the heat source can heat at least the peripheral portion and the central portion of the heating plate separately, and the temperature sensor can also detect at least the peripheral portion and the central portion of the heating plate separately. As a result, the temperature of the hot plate can be made uniform.
また、熱板は、昇温によりそりが発生するが、上側板と
熱板との間の多数の押しねじおよび引きねじを調節する
ことにより、熱板の下面を平坦にすることが可能とな
る。Further, the hot plate causes warpage due to temperature rise, but by adjusting a large number of push screws and pull screws between the upper plate and the hot plate, the lower surface of the hot plate can be made flat. .

押圧力の変更は、重錘15の量を変えることにより行われ
るようになっている。The frame 12 is a lifting device as shown in FIGS.
It is configured to be driven up and down by 14, and a plurality of split weights 15 are placed on the upper surface thereof. The elevating device 14 only elevates and lowers the heat fusion device 3, and the pressing force of the hot plates 4a, 4b, 4c on the tape group 2 is exclusively the weight.
It is given by its own weight of 15. And
The pressing force is changed by changing the amount of the weight 15.
次に、本実施例の作用について説明する。Next, the operation of this embodiment will be described.
格子状熱可塑性ウエブの製造に際しては、テーブル１上
にテープ群２を張設し、その後、各ストリップヒータ８
に通電して熱板4a,4b,4cを加熱する。When manufacturing the lattice-shaped thermoplastic web, the tape group 2 is stretched on the table 1, and then each strip heater 8 is attached.
Is energized to heat the hot plates 4a, 4b, 4c.
ところで、熱板4a,4b,4cを加熱すると、全体としての周
辺部の温度が、放熱により中央部の温度よりも低くな
る。そこで、これを各温度検出センサ９で検出し、全体
の温度が均一になるようにする。By the way, when the heating plates 4a, 4b, 4c are heated, the temperature of the peripheral portion as a whole becomes lower than the temperature of the central portion due to heat radiation. Therefore, this is detected by each temperature detection sensor 9 so that the entire temperature becomes uniform.
また、熱板4a,4b,4cは、加熱によりそりが生じる。そこ
で、引きねじ６および押しねじ７を螺進調節し、熱板4
a,4b,4cの下面が平坦になるようにする。Also, the heating plates 4a, 4b, 4c are warped by heating. Therefore, the draw screw 6 and the push screw 7 are screwed to adjust the heat plate 4
Make the lower surface of a, 4b, 4c flat.
次いで、昇降装置14により熱融着装置３を下降させ、熱
板4a,4b,4cの下面をテープ群２に接触させる。そして、
テープ群２を、熱板4a,4b,4cの熱で加熱しながら、重錘
15の重さで加圧する。これにより、縦方向テープ群と横
方向テープ群との交差部分が熱融着され、格子状のウエ
ブが製造される。Next, the elevating device 14 lowers the heat fusion device 3 to bring the lower surfaces of the heat plates 4a, 4b, 4c into contact with the tape group 2. And
While heating the tape group 2 with the heat of the heating plates 4a, 4b, 4c,
Pressurize with a weight of 15. As a result, the intersecting portions of the vertical tape group and the horizontal tape group are heat-sealed to produce a grid-like web.
ところで、格子状熱可塑性ウエブの幅は、使用目的に合
わせて変化する。この際、熱融着用の熱板4a,4b,4cを一
枚の金属板で形成した場合には、横方向テープ群を引出
すためのチャック等と干渉するおそれがある。By the way, the width of the lattice-shaped thermoplastic web changes according to the purpose of use. At this time, if the heat plates 4a, 4b, 4c for heat fusion are formed of a single metal plate, there is a risk of interference with a chuck or the like for pulling out the lateral tape group.
そこで本実施例では、このような場合には、熱板4b,4c
あるいは熱板4cのみを取外すようになっている。この取
外しは、引きねじ６および押しねじ７を取外すことによ
り、簡単に行なうことができる。そしてこの際、必要に
応じ熱板4b,4cの直上に位置する重錘15を取外すように
してもよい。Therefore, in this embodiment, in such a case, the heating plates 4b, 4c
Alternatively, only the heating plate 4c is removed. This removal can be easily performed by removing the pull screw 6 and the push screw 7. Then, at this time, the weight 15 located directly above the heating plates 4b, 4c may be removed as necessary.
このように、熱板4a,4b,4cに複数のストリップヒータ８
を設置し、温度検出センサ９からの信号で、これらを相
互に独立して制御するようにしているので、熱板4a,4b,
4cの周辺部から放熱しても、全体の温度を均一にするこ
とができる。In this way, the plurality of strip heaters 8 are attached to the heating plates 4a, 4b, 4c.
Are installed and the signals from the temperature detection sensor 9 are used to control these independently of each other. Therefore, the heating plates 4a, 4b,
Even if heat is dissipated from the peripheral portion of 4c, the entire temperature can be made uniform.
また、熱板4a,4b,4cは加熱によりそりが生じることにな
るが、多数の引きねじ６および押しねじ７で、これを修
正できるようにしているので、熱板4a,4b,4cの下面を完
全な平坦面にすることができる。このため、温度が均一
であることと相俟って、熱融着部の強度を安定させるこ
とができる。Also, the heating plates 4a, 4b, 4c will be warped due to heating, but since it is possible to correct this with a large number of drawing screws 6 and push screws 7, the lower surface of the heating plates 4a, 4b, 4c Can be a perfectly flat surface. Therefore, in combination with the uniform temperature, the strength of the heat-sealed portion can be stabilized.
また、熱板4a,4b,4cからテープ群２に与えられる押圧力
は、空気シリンダやスクリュージャッキ等の機械力によ
り得るのではなく、重錘15の自重により得るようにして
いるので、押圧力が局部に集中的に付与されることな
く、熱板4a,4b,4cの各部に均等に付与される。このた
め、熱融着を安定させることができる。Further, the pressing force applied to the tape group 2 from the heat plates 4a, 4b, 4c is not obtained by the mechanical force of the air cylinder or the screw jack, but is obtained by the weight of the weight 15 itself. Is uniformly applied to each part of the heat plates 4a, 4b, 4c without being intensively applied to local parts. Therefore, heat fusion can be stabilized.
また、３つの熱板4a,4b,4cを用いるようにしているの
で、製造すべき格子状熱可塑性ウエブの幅に合わせ、熱
板の幅を調節することができる。そしてこの際、引きね
じ６および押しねじ７を取外すだけで、熱板の幅を調節
できるので、作業が容易である。Further, since the three hot plates 4a, 4b, 4c are used, the width of the hot plates can be adjusted according to the width of the lattice-shaped thermoplastic web to be manufactured. At this time, the width of the hot plate can be adjusted simply by removing the pulling screw 6 and the pushing screw 7, which facilitates the work.
本発明者等は、熱板4a,4b,4cの合計の面積を1600mm×50
0mmとした熱融着装置３を用い、交差部分の数が約3000
のテープ群２の熱融着を行なった。The present inventors have set the total area of the heat plates 4a, 4b, 4c to 1600 mm × 50.
The number of intersections is about 3000 using the heat fusion device 3 with 0 mm
The tape group 2 was heat-sealed.
その結果、いずれの交差部分の融着も強固で、融着後の
二次加工でも、剥離する箇所はなかった。また、熱板4
a,4b,4cの温度は、各所均一で温度差がほとんどなく、
熱融着には全く支障がないことが判った。As a result, the fusion bonding at any intersection was strong, and there was no peeling spot even in the secondary processing after fusion. Also, the heat plate 4
The temperatures of a, 4b and 4c are uniform in each place and there is almost no difference in temperature.
It was found that there was no problem with heat fusion.
なお、前記実施例においては、３分割構造の熱板4a,4b,
4cを用いる場合について説明したが、２分割でも４分割
以上でもよい。また、ストリップヒータ８および温度検
出センサ９は、熱板の少なくとも周辺部と中央部とを分
けて制御、検出できるものであれば、前記実施例の配
列、個数に限定されるものではない。In the above embodiment, the heating plates 4a, 4b, and
Although the case of using 4c has been described, it may be divided into two or four or more. Further, the strip heater 8 and the temperature detection sensor 9 are not limited to the arrangement and the number of the above-mentioned embodiments as long as they can control and detect at least the peripheral portion and the central portion of the heating plate separately.
以上説明したように本発明は、熱板を加熱する熱源とし
て、熱板の少なくとも周辺部と中央部とを分けて加熱で
きるものを用いるとともに、温度センサとして、熱板の
少なくとも周辺部と中央部とを分けて検出できるものを
用いるようにしているので、熱板の周辺部からの放熱が
あっても、熱板の全体を均一温度にすることができる。As described above, the present invention uses, as the heat source for heating the hot plate, one capable of separately heating at least the peripheral portion and the central portion of the hot plate, and as the temperature sensor, at least the peripheral portion and the central portion of the hot plate. Therefore, even if heat is radiated from the peripheral portion of the hot plate, the entire hot plate can be made to have a uniform temperature.
また、熱板の上方に上側板を設け、この上側板と熱板と
の間に、熱板の平面度を調節する多数の押しねじおよび
引きねじを配置するようにしているので、加熱により熱
板にそりが生じた場合でも、これを修正し、熱板の仮面

に加熱されることと相俟って、縦、横両方向のテープ群
の交差部分を、安定して熱融着することができ、品質の
高い格子状熱可塑性ウエブを製造することができる。In addition, since an upper plate is provided above the hot plate and a large number of push screws and pull screws for adjusting the flatness of the hot plate are arranged between the upper plate and the hot plate, the heat generated by heating is reduced. Even if the plate is warped, it can be corrected to flatten the temporary surface of the hot plate. Therefore, coupled with the fact that the hot plate is heated to a uniform temperature, the intersecting portions of the tape groups in both the vertical and horizontal directions can be stably heat-sealed, and a high-quality lattice-shaped thermoplastic web can be obtained. Can be manufactured.
