発明が解決しょうとする課題  Problems to be solved by the invention
[0003] 上述のような加熱装置では、熱収縮チューブが設置された部材が順次投入され、 熱収縮チューブが加熱されて収縮した後、その部材が冷却されてから回収されるが、 当該回収された部材はコンベア装置の終端側において積重ねられた状態で蓄積さ れる。そして、これらの部材が回収され、積重ねられる際に、加熱装置の操業条件に よっては当該部材の熱収縮チューブが十分に冷却されていない場合があった。この ように熱収縮チューブが十分冷却されていない状態で複数の部材が積層されると、 熱収縮チューブが他の部材と接触することで変形し、部材の仕上り外観が悪ィ匕し、さ らには熱収縮チューブによる固定 '封止といった機能が損なわれる（つまり熱収縮チ ユーブの品質が劣化する)ことがあった。 [0003] In the heating device as described above, the members on which the heat shrinkable tubes are installed are sequentially put in, and after the heat shrinkable tubes are heated and shrunk, the members are cooled and then collected. The accumulated members are accumulated in a stacked state on the terminal side of the conveyor device. When these members are collected and stacked, the heat-shrinkable tube of the member may not be sufficiently cooled depending on the operating conditions of the heating device. When a plurality of members are stacked in a state where the heat shrink tube is not sufficiently cooled in this way, the heat shrink tube is deformed by coming into contact with other members, and the finished appearance of the member is deteriorated. In some cases, the function of fixing and sealing with a heat-shrinkable tube was impaired (that is, the quality of the heat-shrinkable tube deteriorated).
[0004] また、熱収縮チューブの内周側に熱溶融性接着剤が配置されて!ヽる場合もある。こ の場合に、熱収縮チューブが十分冷却されていない状態で複数の部材が積層され ると、当該熱溶融性接着剤において外側に露出している部分が他の部材などと接触 •固着し、やはり部材の仕上り外観が悪ィ匕し、さらに熱収縮チューブによる固定 ·封止 という機能が十分に発揮されない状態になる場合があった。 [0004] In some cases, a hot-melt adhesive is disposed on the inner peripheral side of the heat-shrinkable tube. In this case, if a plurality of members are stacked while the heat-shrinkable tube is not sufficiently cooled, the exposed portion of the heat-meltable adhesive contacts other members. • There were cases in which the finished appearance of the member deteriorated, and the function of fixing / sealing with the heat shrinkable tube could not be fully exhibited.
[0005] この発明は、上記のような課題を解決するために成されたものであり、この発明の目 的は、熱収縮チューブが設置された部材を加熱した後、当該部材を十分冷却してか ら回収することで部材の仕上り外観や品質の劣化を防止することが可能な熱収縮チ ユーブ用加熱装置を提供することである。  [0005] The present invention has been made to solve the above-described problems, and the object of the present invention is to sufficiently cool the member after heating the member on which the heat-shrinkable tube is installed. It is to provide a heating device for a heat-shrinkable tube that can prevent deterioration of the finished appearance and quality of a member by collecting it from the beginning.

[0011] (実施の形態 1)  [0011] (Embodiment 1)
図 1〜図 3を参照して、本発明による加熱装置の実施の形態 1を説明する。  A first embodiment of the heating device according to the present invention will be described with reference to FIGS.
[0012] 図 1を参照して、加熱装置 1は下部筐体 2と上部筐体 4と制御装置 22とにより構成さ れている。下部筐体 2には、ローラ 7a、 7bの間に架け渡された下ベルト 6と、この下べ ルト 6を駆動するためのモータ 3と、このモータ 3によって同様に駆動される歯車 10と が設置されている。また、下部筐体 2には、下ベルト 6と、後述する上ベルト 5との間に 投入された熱収縮チューブが設置された部材を加熱するためのヒータ 8が設置され ている。また、下ベルト 6の出口側（歯車 10側）には熱収縮チューブが設置された部 材を歯車 10に案内するためのガイド 13が設置されている。下ベルト 6は、モータ 3に よって発生した駆動力が動力伝達部 11を介してローラ 7aに伝えられることにより、矢 印 19に示す方向に回転可能となって 、る。  Referring to FIG. 1, heating device 1 includes a lower housing 2, an upper housing 4, and a control device 22. The lower casing 2 includes a lower belt 6 spanned between the rollers 7a and 7b, a motor 3 for driving the lower belt 6, and a gear 10 similarly driven by the motor 3. is set up. Further, the lower housing 2 is provided with a heater 8 for heating a member provided with a heat-shrinkable tube inserted between the lower belt 6 and an upper belt 5 described later. In addition, a guide 13 for guiding the member on which the heat-shrinkable tube is installed to the gear 10 is installed on the outlet side (the gear 10 side) of the lower belt 6. The lower belt 6 can be rotated in the direction indicated by an arrow 19 when the driving force generated by the motor 3 is transmitted to the roller 7 a via the power transmission unit 11.
[0013] なお、制御装置 22の制御によってモータ 3の回転を逆転させることにより、下ベルト 6は矢印 19に示す方向と逆方向に回転させることも可能である。また、歯車 10もモー タ 3の駆動力が動力伝達部 12を介して伝えられることにより、矢印 20に示す方向に 回転可能となっている。  Note that the lower belt 6 can be rotated in the direction opposite to the direction indicated by the arrow 19 by reversing the rotation of the motor 3 under the control of the control device 22. Further, the gear 10 can also rotate in the direction indicated by the arrow 20 by transmitting the driving force of the motor 3 via the power transmission unit 12.
[0014] 歯車 10にはその外周部に複数の歯 38が設置されている。複数の歯 38は互いに間 隔を隔てて形成されており、この歯 38の間に熱収縮チューブが設置された部材（下 ベルト 6と上ベルト 5との間を搬送され、搬出された部材)を保持するための凹部 39が 形成されている。 The gear 10 is provided with a plurality of teeth 38 on the outer periphery thereof. The teeth 38 are A recess 39 is formed to hold a member (a member conveyed between the lower belt 6 and the upper belt 5 and carried out) between which the teeth 38 are formed. Is formed.
[0015] 上部筐体 4には、下部筐体に設置された下ベルト 6と対向する位置に、ローラ 7c、 7 dの間に架け渡された状態で上ベルト 5が設置されている。また、上部筐体 4には、下 部筐体 2と同様に熱収縮チューブが設置された部材を加熱するためのヒータ 8が設 置されている。さらに、上部筐体 4には、ヒータ 8の後方 (ヒータ 8から見て歯車 10側） に、ヒータ 8によって加熱された後の部材を冷却するための送風ファン 15が設置され ている。上ベルト 5は、下ベルト 6と同様に、矢印 19に示す方向および矢印 19に示す 方向と逆方向に回転可能になっている。上ベルト 5を回転させる駆動力は、下部筐体 2に設置されたモータ 3によって発生された駆動力を用いてもよいし、他の動力源に より発生したものを用いてもよい。また、上部筐体 4の上部表面上にはヒータ 8の温度 状態を表示するための表示ライト 17が設置されている。また、図 1に示すように 2つの ヒータ 8の表面には熱電対 24がそれぞれ設置されている。  In the upper housing 4, an upper belt 5 is installed at a position facing the lower belt 6 installed in the lower housing in a state of being spanned between the rollers 7 c and 7 d. In addition, the upper casing 4 is provided with a heater 8 for heating the member on which the heat-shrinkable tube is installed in the same manner as the lower casing 2. Further, the upper casing 4 is provided with a blower fan 15 for cooling the member heated by the heater 8 behind the heater 8 (on the side of the gear 10 when viewed from the heater 8). Similar to the lower belt 6, the upper belt 5 is rotatable in the direction indicated by the arrow 19 and in the direction opposite to the direction indicated by the arrow 19. As the driving force for rotating the upper belt 5, the driving force generated by the motor 3 installed in the lower housing 2 may be used, or the driving force generated by another power source may be used. An indicator light 17 for displaying the temperature state of the heater 8 is installed on the upper surface of the upper casing 4. Further, as shown in FIG. 1, thermocouples 24 are respectively installed on the surfaces of the two heaters 8.
[0016] 下部筐体 2の後方 (歯車 10が配置された側）には、制御装置 22が配置されて 、る。  A control device 22 is disposed behind the lower housing 2 (on the side where the gear 10 is disposed).
制御装置 22は、後述するようにモータ 3やヒータ 8などの、加熱装置 1を構成する機 器の動作を制御するためのものである。また、上部筐体 4は、たとえば歯車 10が設置 された側に設置された回転軸を中心として、上方に開放することが可能になっていて もよい。このようにすれば、上ベルト 5や下ベルト 6、ヒータ 8やモータ 3などのメンテナ ンスを容易に行なうことができる。  The control device 22 is for controlling the operation of the devices constituting the heating device 1, such as the motor 3 and the heater 8, as will be described later. Further, the upper housing 4 may be capable of being opened upward, for example, around a rotating shaft installed on the side where the gear 10 is installed. In this way, maintenance of the upper belt 5, the lower belt 6, the heater 8 and the motor 3 can be easily performed.
[0017] なお、上述した上ベルト 5および下ベルト 6は、図 2に示すようにそれぞれ上部筐体 4および下部筐体 2において 2つずつ設置されている。すなわち、下ベルト 6は下部 筐体 2の上方において図 2に示すように互いに間隔を隔ててほぼ平行に並ぶように 配置されている。そして、この 2つの下ベルト 6の間にヒータ 8が設置されている。また 、上部筐体 4においても、 2つの上ベルト 5が互いに間隔を隔てて平行に延びるように 配置されている。また、ヒータ 8は 2本の上ベルト 5の間に配置されている。上ベルト 5 および下ベルト 6は、上下方向に重なるように（つまり、上ベルト 5と下ベルト 6との間に 搬送対象物を挟んで保持することができるように)配置されて ヽる。 [0018] また、上ベルト 5と下ベルト 6との組の後方には、それぞれガイド 13と歯車 10とが配 置されている。 2つのガイド 13の幅はたとえば上ベルト 5や下ベルト 6の幅と同じであ つてもよい。また、上ベルト 5と下ベルト 6との組の後方に配置された歯車 10は、それ ぞれ共通の回転軸に固定されており、当該回転軸が回転することにより同期して回 転可能になっている。 Note that two upper belts 5 and lower belts 6 are provided in the upper housing 4 and the lower housing 2, respectively, as shown in FIG. That is, the lower belt 6 is arranged above the lower casing 2 so as to be arranged in parallel with a distance from each other as shown in FIG. A heater 8 is installed between the two lower belts 6. Also in the upper housing 4, the two upper belts 5 are arranged so as to extend in parallel with a distance from each other. The heater 8 is disposed between the two upper belts 5. The upper belt 5 and the lower belt 6 are arranged so as to overlap in the vertical direction (that is, the conveyance object can be held between the upper belt 5 and the lower belt 6). [0018] Further, a guide 13 and a gear 10 are arranged behind the set of the upper belt 5 and the lower belt 6, respectively. The widths of the two guides 13 may be the same as the widths of the upper belt 5 and the lower belt 6, for example. In addition, the gears 10 arranged behind the pair of the upper belt 5 and the lower belt 6 are fixed to a common rotating shaft, and can be rotated synchronously by rotating the rotating shaft. It has become.
[0019] このような構成とすることにより、つまり上ベルト 5および下ベルト 6の組を、間隔を隔 てて平行に延びるように 2つ配置することで、それぞれの組の上ベルト 5および下べ ルト 6の間に熱収縮チューブが設置された部材を順番に挟み込んで保持することが できる。このとき、部材において熱収縮チューブが設置された部分を下ベルト 6およ び上ベルト 5の組の間（すなわちヒータ 8と対向する部分）〖こ位置するように、部材の 両端部を上ベルト 5および下ベルト 6のそれぞれの組により挟むように保持する。そし て、上ベルト 5および下ベルト 6が図 1の矢印 19に示す方向に回転することにより、部 材は投入口側から搬出口側 (歯車 10が配置された側)へ搬送される。  [0019] By adopting such a configuration, that is, by arranging two sets of the upper belt 5 and the lower belt 6 so as to extend in parallel at an interval, the upper belt 5 and the lower belt of each set are arranged. A member having a heat-shrinkable tube placed between the belts 6 can be sandwiched and held in order. At this time, both ends of the member are positioned on the upper belt so that the portion where the heat shrink tube is installed is positioned between the lower belt 6 and the upper belt 5 (that is, the portion facing the heater 8). 5 and the lower belt 6 are held so as to be sandwiched between them. Then, when the upper belt 5 and the lower belt 6 rotate in the direction indicated by the arrow 19 in FIG. 1, the parts are conveyed from the inlet side to the carry-out side (side on which the gear 10 is disposed).
[0020] ここで、加熱装置 1の装置構成を図 3に示したブロック図を用いて制御面力 説明 する。図 3に示すように、加熱装置 1は、制御装置 22と、この制御装置 22に接続され たモータ 3、ヒータ 8、送風ファン 15、表示ライト 17、熱電対 24を備えている。制御装 置 22により、モータ 3において発生する駆動力の回転方向や回転速度は変更可能と なっている。また、ヒータ 8の温度も制御装置 22により変更可能になっている。さらに 、表示ライト 17は、複数の異なる色の光を出力できるようになっており、これらの光の ONZOFFや、光の色の切替が制御装置 22により可能になっている。また、熱電対 24においてヒータ 8の温度が測定され、当該測定結果のデータが制御装置 22に送 られる。制御装置 22では、当該測定結果のデータに基づいて、後述するように加熱 装置 1の制御を行なうことができる。  Here, the control surface force will be described with reference to the block diagram shown in FIG. As shown in FIG. 3, the heating device 1 includes a control device 22, a motor 3, a heater 8, a blower fan 15, a display light 17, and a thermocouple 24 connected to the control device 22. The rotation direction and speed of the driving force generated in the motor 3 can be changed by the control device 22. Further, the temperature of the heater 8 can be changed by the control device 22. In addition, the display light 17 can output a plurality of different colors of light, and the control device 22 can switch these lights ONZOFF and light colors. Further, the temperature of the heater 8 is measured by the thermocouple 24, and data of the measurement result is sent to the control device 22. The control device 22 can control the heating device 1 as described later based on the data of the measurement result.
[0021] 次に、図 1〜図 3に示した加熱装置の動作を簡単に説明する。まず、熱収縮チュー ブがその中央部に設置された複数の部材を準備する。そして、図 1に示した投入口 側から当該部材を順番に加熱装置 1に投入する。具体的には、部材において熱収縮 チューブが設置された部分以外の部分（当該部材の両端部）を、上ベルト 5および下 ベルト 6の 2つの組のそれぞれに挟み込むことにより保持させる。このとき、上ベルト 5 および下ベルト 6はモータ 3からの駆動力によって図 1の矢印 19に示す方向に回転し ている。この結果、上ベルト 5および下ベルト 6の組により保持された複数の部材は、 投入口側から加熱部 9、冷却部 14を介して歯車 10が設置された個別冷却部 16側（ 搬出口側)へと搬送される。 Next, the operation of the heating apparatus shown in FIGS. 1 to 3 will be briefly described. First, a plurality of members in which a heat shrinkable tube is installed at the center thereof are prepared. Then, the members are sequentially inserted into the heating apparatus 1 from the inlet side shown in FIG. Specifically, the members other than the portion where the heat-shrinkable tube is installed (both ends of the member) are held by being sandwiched between two sets of the upper belt 5 and the lower belt 6, respectively. At this time, upper belt 5 The lower belt 6 is rotated in the direction indicated by the arrow 19 in FIG. As a result, the plurality of members held by the set of the upper belt 5 and the lower belt 6 are separated from the charging port side through the heating unit 9 and the cooling unit 14 to the individual cooling unit 16 side (the carry-out port side). ).
[0022] そして、この搬送途中において、部材に設置された熱収縮チューブが加熱部 9にお いてヒータ 8により加熱される。この結果、当該部材に設置された熱収縮チューブが 熱収縮する。このようにして、ヒータ 8と対向する部分 (加熱部 9)を通過した部材にお いては、熱収縮チューブが熱収縮することにより当該熱収縮チューブが設置された 部分が固定および Zまたは封止される。  [0022] During this conveyance, the heat-shrinkable tube installed on the member is heated by the heater 8 in the heating unit 9. As a result, the heat-shrinkable tube installed on the member heat-shrinks. In this way, in the member that has passed through the portion facing the heater 8 (heating portion 9), the portion where the heat shrinkable tube is installed is fixed and Z or sealed due to heat shrinkage of the heat shrinkable tube. Is done.
[0023] そして、ヒータ 8による加熱が終わった後（ヒータ 8と対向する部分を通過した後）、当 該部材は送風ファン 15の下方（冷却部 14)を通過する。この送風ファン 15からは、上 ベルト 5および下ベルト 6に保持されている部材に対して (特に熱収縮チューブに対 して)冷却風が吹き付けられる。この冷却風によって、熱収縮チューブの温度が下げ られる。そして、さらに上ベルト 5および下ベルト 6が矢印 19に示す方向に回転するこ とにより、上ベルト 5および下ベルト 6の搬出口側から熱収縮チューブが設置された部 材が搬出される。  [0023] Then, after the heating by the heater 8 is finished (after passing through a portion facing the heater 8), the member passes under the blower fan 15 (cooling unit 14). From the blower fan 15, cooling air is blown against the members held by the upper belt 5 and the lower belt 6 (particularly against the heat-shrinkable tube). This cooling air reduces the temperature of the heat-shrinkable tube. Further, when the upper belt 5 and the lower belt 6 are further rotated in the direction indicated by the arrow 19, the member on which the heat-shrinkable tube is installed is carried out from the carry-out side of the upper belt 5 and the lower belt 6.
[0024] 搬出された部材は、個別冷却部 16へ移送される。具体的には、当該部材において 上ベルト 5および下ベルト 6により保持されていた部分がガイド 13により案内されるこ とにより、歯車 10の凹部 39に保持される。なお、歯車 10は、図 2に示すように 2つの 下ベルト 6の後方にそれぞれ設置されている。そして、これらの 2つの歯車 10により、 熱収縮チューブが設置された部材において熱収縮チューブが設置された部分を挟 む両端の位置が保持される。部材をその凹部 39に保持した 2つの歯車 10は、回転 軸を中心として図 1の矢印 20に示す方向に回転する。この結果、部材において熱収 縮チューブが設置された部分が他の部材ゃ加熱装置の構成部材と接触することなく 、部材を個別に保持した状態で冷却することができる。  The member carried out is transferred to the individual cooling unit 16. Specifically, the portion held by the upper belt 5 and the lower belt 6 in the member is guided by the guide 13 and thereby held in the recess 39 of the gear 10. The gears 10 are respectively installed behind the two lower belts 6 as shown in FIG. These two gears 10 hold the positions of both ends of the member where the heat-shrinkable tube is installed across the portion where the heat-shrinkable tube is installed. The two gears 10 holding the member in the recess 39 rotate around the rotation axis in the direction indicated by the arrow 20 in FIG. As a result, the part where the heat-condensing tube is installed in the member can be cooled in a state where the member is individually held without coming into contact with the other member or the constituent member of the heating device.
[0025] そして、投入ロカ 順次熱収縮チューブが設置された部材を投入することにより、 部材の熱収縮チューブを順次加熱，収縮し、その後、加熱後の部材を矢印 20の方 向に回転している歯車 10のそれぞれの凹部 39に個別に保持することができる。そし て、この歯車 10の凹部 39に個別に当該部材が保持された状態で、歯車 10がゆつく り回転している間に、当該部材の熱収縮チューブが設置された部分が十分に冷却さ れる。このため、他の部材と、十分冷却される前の熱収縮チューブとが固着して変形 するといつた問題の発生を抑制できる。その後、歯車 10の回転により、部材が保持さ れる凹部 39が歯車 10の下側になる。すると、それまでの時間で十分に冷却された当 該部材は、凹部 39から落下することにより歯車 10の下方に搬出される。 [0025] Then, by inserting a member in which the heat shrink tube is sequentially installed, the heat shrink tube of the member is sequentially heated and shrunk, and then the heated member is rotated in the direction of the arrow 20 Can be held individually in each recess 39 of the gear 10. And Thus, while the member is individually held in the recess 39 of the gear 10, the portion of the member where the heat-shrinkable tube is installed is sufficiently cooled while the gear 10 is rotating slowly. . For this reason, it is possible to suppress the occurrence of problems when other members and the heat-shrinkable tube before being sufficiently cooled are fixed and deformed. Thereafter, the concave portion 39 in which the member is held is located below the gear 10 by the rotation of the gear 10. Then, the member that has been sufficiently cooled in the time until then falls from the recess 39 and is carried out below the gear 10.
[0026] 次に、表示ライト 17に関する制御内容を、図 4を参照しながら説明する。当該制御 は制御装置 22において実施される。なお、表示ライト 17は、ヒータ 8の温度条件につ いての情報をオペレータなどに報知するためのものである。  Next, the contents of control related to the display light 17 will be described with reference to FIG. The control is performed in the control device 22. The display light 17 is for notifying an operator or the like of information about the temperature condition of the heater 8.
[0027] 図 4に示すように、表示ライト 17 (図 1参照）に関する制御では、まず測温工程 (S10 )を実施する。この測温工程（S10)においては、図 1の熱電対 24によりヒータ 8の温 度を測定する。熱電対 24により測定されたヒータ 8の温度データは、制御装置 22へ 出力される。  As shown in FIG. 4, in the control related to the display light 17 (see FIG. 1), first, a temperature measuring step (S10) is performed. In this temperature measurement step (S10), the temperature of the heater 8 is measured by the thermocouple 24 in FIG. The temperature data of the heater 8 measured by the thermocouple 24 is output to the control device 22.
[0028] 次に、温度条件の判定工程 (S20)を実施する。この温度条件の判定工程 (S20) においては、制御装置 22へ熱電対 24から入力された測定データに基づいて、熱収 縮チューブが設置された部材を加熱するための設定温度範囲の中に、ヒータ 8の温 度が入っているかどうかを判定する。この設定温度範囲は制御装置 22に予め記憶さ れている。  [0028] Next, a temperature condition determination step (S20) is performed. In this temperature condition determination step (S20), based on the measurement data input from the thermocouple 24 to the control device 22, within the set temperature range for heating the member on which the heat-condensing tube is installed, Judge whether the heater 8 temperature is on. This set temperature range is stored in the controller 22 in advance.
[0029] 次に、表示制御工程 (S30)を実施する。具体的には、ヒータ 8の温度が設定温度 範囲内にある場合には、表示ライト 17から緑色の光を出射する。一方、ヒータ 8の温 度が設定温度範囲よりも高くなつている場合には、表示ライト 17から赤い光を出射す る。また、ヒータ 8の温度が設定温度範囲よりも低い場合には、表示ライト 17から黄色 の光を出射する。このように、表示ライト 17の発光色により、加熱装置 1の使用者 (ォ ペレータ）はヒータ 8の温度が設定温度範囲内に入っているかどうかを容易に確認す ることができる。なお、表示ライト 17の構成としては、上述のような緑色、赤色、黄色の ライトを備えるようなものとしてもよいし、たとえば上述した各色を表示可能な表示装置 を用いてもよい。また、色による報知に加えて、たとえばスピーカを制御装置 22に接 続しておき、上述した各色の光の出射に合わせて、異なる音をスピーカから出力する ようにしてもよい。 Next, a display control step (S30) is performed. Specifically, when the temperature of the heater 8 is within the set temperature range, green light is emitted from the display light 17. On the other hand, when the temperature of the heater 8 is higher than the set temperature range, red light is emitted from the display light 17. Further, when the temperature of the heater 8 is lower than the set temperature range, yellow light is emitted from the display light 17. As described above, the user (operator) of the heating device 1 can easily confirm whether or not the temperature of the heater 8 is within the set temperature range by the emission color of the display light 17. The display light 17 may be configured to include the green, red, and yellow lights as described above, or a display device that can display each color described above, for example. In addition to the notification by color, for example, a speaker is connected to the control device 22, and different sounds are output from the speaker in accordance with the emission of light of each color described above. You may do it.
[0030] 次に、加熱装置が稼動中であるかどうかを判定する工程 (S40)が実施される。ここ で、加熱装置 1が稼動中であると判断された場合には、工程 (S40)において YESと 判定され再び測温工程（S 10)以下の工程が実施される。一方、工程（S40)におい て、加熱装置が稼動中ではない、すなわち加熱装置の稼動が終了することが検出さ れた場合には、 NOと判定され後処理工程 (S50)が実施される。当該後処理工程 (S 50)においては、表示ライト 17を消灯するといつた後処理が実施される。このようにし て、表示ライト 17に関する制御が実施される。  [0030] Next, a step (S40) of determining whether or not the heating device is in operation is performed. Here, when it is determined that the heating apparatus 1 is in operation, it is determined YES in the step (S40), and the steps after the temperature measurement step (S10) are performed again. On the other hand, in the step (S40), when it is detected that the heating device is not in operation, that is, the operation of the heating device is finished, it is determined as NO and the post-processing step (S50) is performed. In the post-processing step (S50), when the display light 17 is turned off, the post-processing is performed. In this way, control relating to the display light 17 is performed.
[0031] 次に、図 1〜図 3に示した加熱装置 1における、不良品（異常品）の混入を防ぐため の制御を、図 5を参照しながら説明する。  Next, control for preventing the introduction of defective products (abnormal products) in the heating apparatus 1 shown in FIGS. 1 to 3 will be described with reference to FIG.
[0032] 図 5に示すように、不良品の混入を防ぐ制御としては、まず測温工程 (S10)が実施 される。この測温工程（S10)は、図 4に示した測温工程（S10)と同様に、ヒータ 8の 表面に設置された熱電対 24により、ヒータ 8の温度を測定する。当該熱電対 24にお いて測定された温度データは、制御装置 22に出力される。  [0032] As shown in FIG. 5, as a control for preventing the introduction of defective products, a temperature measuring step (S10) is first performed. In this temperature measurement step (S10), the temperature of the heater 8 is measured by the thermocouple 24 installed on the surface of the heater 8, similarly to the temperature measurement step (S10) shown in FIG. The temperature data measured by the thermocouple 24 is output to the control device 22.
[0033] 次に、温度条件の判定工程 (S60)が実施される。この判定工程 (S60)にお 、て、 ヒータ 8の温度が設定温度範囲内にある場合には、 YESと判定され、再度測温工程 ( 10)が実施される。一方、判定工程 (S60)において、ヒータ 8の温度が設定温度範囲 内に入っていないと判断された場合には、 NOと判定されることになる。この結果、投 入不可制御（S70)が実施される。  Next, a temperature condition determining step (S60) is performed. In this determination step (S60), if the temperature of the heater 8 is within the set temperature range, it is determined YES and the temperature measurement step (10) is performed again. On the other hand, if it is determined in the determination step (S60) that the temperature of the heater 8 is not within the set temperature range, the determination is NO. As a result, the investment impossible control (S70) is performed.
[0034] 投入不可制御（S70)では、具体的には、制御装置 22からモータ 3へ制御信号が 出力されることにより、モータ 3の出力する駆動力の回転方向が通常状態とは逆にな る。このため、上ベルト 5および下ベルト 6の回転方向力 図 1に示した矢印 19の方向 (通常状態での回転方向）と逆方向になる。この結果、熱収縮チューブが設置された 部材を投入口側力も投入することができなくなるとともに、既に投入ロカも上ベルト 5 および下ベルト 6の間に保持されて搬送されることにより、ヒータ 8によって加熱されて いた部材も投入口側から逆向きに搬出されることになる。このような上ベルト 5および 下ベルト 6の逆転制御は、上ベルト 5および下ベルト 6の間に保持されていた部材が すべて投入口側カゝら搬出されるまで行なわれる。ぐたいてきには、上ベルト 5および 下ベルト 6が少なくとも半周分逆転するように、上記逆転制御は実施される。 [0034] In the injection disable control (S70), specifically, when the control signal is output from the control device 22 to the motor 3, the rotation direction of the driving force output from the motor 3 is reversed from the normal state. The For this reason, the rotational direction force of the upper belt 5 and the lower belt 6 is opposite to the direction of the arrow 19 shown in FIG. 1 (the rotational direction in the normal state). As a result, the member on which the heat-shrinkable tube is installed cannot be charged with the inlet side force, and the charging roller is already held and transported between the upper belt 5 and the lower belt 6 so that the heater 8 The heated member is also transported in the opposite direction from the inlet side. Such reverse rotation control of the upper belt 5 and the lower belt 6 is performed until all the members held between the upper belt 5 and the lower belt 6 are carried out from the insertion port side. For the most part, the upper belt 5 and The reverse rotation control is performed so that the lower belt 6 reverses at least a half turn.
[0035] このため、ヒータ 8の温度が設定温度範囲内に入っていない状態で加熱された部材  Therefore, the member heated in a state where the temperature of the heater 8 is not within the set temperature range
(すなわち不良品の発生している可能性が高いと思われる部材）は、加熱装置の搬 出口側ではなく投入口側から搬出される。この結果、加熱装置 1から通常通り搬出さ れた部材に、加熱温度条件が設定温度範囲外となった状態で加熱処理された不良 品である可能性の高い部材が混入することを確実に防止することができる。  (In other words, a member that is likely to have a defective product) is carried out from the inlet side, not the outlet side of the heating device. As a result, it is possible to reliably prevent a member that is normally removed from the heating device 1 from being mixed with a member that is likely to be a defective product that has been heat-treated while the heating temperature condition is outside the set temperature range. can do.
[0036] 次に、図 6を参照して、図 1〜図 3に示した加熱装置の第 1の変形例を説明する。  Next, a first modification of the heating apparatus shown in FIGS. 1 to 3 will be described with reference to FIG.
図 6に示した加熱装置 1は、基本的には図 1〜図 3に示した加熱装置 1と同様の構 造を備えるが、歯車 10へモータ 3から駆動力を伝える部材として変速機構としてのギ ャ部 25を用いている点が異なっている。すなわち、このギヤ部 25においてモータ 3の 回転数に対する歯車 10の回転数の比（ギヤ比）を変更することにより、上ベルト 5およ び下ベルト 6の移動速度に対する歯車 10の回転速度を任意に調整することができる 。この結果、歯車 10において、熱収縮チューブが設置された部材の保持される時間 を任意に調節することができる。  The heating device 1 shown in FIG. 6 basically has the same structure as the heating device 1 shown in FIGS. 1 to 3, but serves as a transmission mechanism as a member that transmits the driving force from the motor 3 to the gear 10. The difference is that gear section 25 is used. That is, by changing the ratio of the rotation speed of the gear 10 to the rotation speed of the motor 3 (gear ratio) in the gear portion 25, the rotation speed of the gear 10 with respect to the movement speed of the upper belt 5 and the lower belt 6 can be arbitrarily set. Can be adjusted to. As a result, in the gear 10, it is possible to arbitrarily adjust the holding time of the member on which the heat-shrinkable tube is installed.
[0037] 次に、図 7を参照して、図 1〜図 3に示した加熱装置の第 2の変形例を説明する。  Next, a second modification of the heating device shown in FIGS. 1 to 3 will be described with reference to FIG.
図 7に示した加熱装置 1は、基本的には図 1〜図 3に示した加熱装置 1と同様の構 成を備えるが、歯車 10の外周に沿うように、カバー 27が設置されている点が異なつ ている。このカバー 27は、歯車 10の側部から歯車 10の真下の部分にまで延在する ように形成されている。このカバー 27が設置されることにより、カバー 27における歯車 10下側の端部にまで、部材が凹部 39に保持された状態を維持することができる。つ まり、凹部 39が歯車 10の真下の領域に来る前に、当該凹部 39から部材が落下する ことを防止できる。この結果、歯車 10の凹部 39に部材が保持される時間を、カバー 2 7が設置されて 、な 、場合より長くすることができる。  The heating device 1 shown in FIG. 7 basically has the same configuration as the heating device 1 shown in FIGS. 1 to 3, but a cover 27 is installed along the outer periphery of the gear 10. The points are different. The cover 27 is formed so as to extend from the side of the gear 10 to a portion directly below the gear 10. By installing the cover 27, the state in which the member is held in the recess 39 can be maintained up to the end of the cover 27 on the lower side of the gear 10. In other words, it is possible to prevent the member from dropping from the concave portion 39 before the concave portion 39 reaches the region directly below the gear 10. As a result, the time for which the member is held in the recess 39 of the gear 10 can be made longer than the case where the cover 27 is installed.
[0038] 次に、図 8を参照して、図 1〜図 3に示した加熱装置の第 3の変形例を説明する。  Next, a third modification of the heating device shown in FIGS. 1 to 3 will be described with reference to FIG.
図 8に示した加熱装置は、基本的には図 1〜図 3に示した加熱装置 1と同様の構造 を備えるが、歯車 10に保持された部材をより効率的に冷却するため、歯車 10に向け て冷却風を供給するための冷却部材として送風ファン 15が設置されている点が異な つている。送風ファン 15は、下部筐体 2において歯車 10に向けて冷却風を送出する ことができるように設置されている。このようにすれば、歯車 10における凹部 39に個 別に保持された部材をより効率的に冷却することができる。 The heating device shown in FIG. 8 basically has the same structure as the heating device 1 shown in FIGS. 1 to 3, but in order to cool the members held by the gear 10 more efficiently, the gear 10 The difference is that a blower fan 15 is installed as a cooling member for supplying cooling air toward the air. The blower fan 15 sends cooling air toward the gear 10 in the lower housing 2. It is installed so that it can. In this way, the members individually held in the recesses 39 in the gear 10 can be cooled more efficiently.
[0039] 次に、図 9を参照して、図 1〜図 3に示した加熱装置の第 4の変形例を説明する。  Next, a fourth modification of the heating device shown in FIGS. 1 to 3 will be described with reference to FIG.
図 9に示した加熱装置 1は、基本的には図 1〜図 3に示した加熱装置 1と同様の構 造を備えるが、 2つの送風ファン 15a、 15bが下部筐体 2に設置されている点が異な る。すなわち、送風ファン 15aは、図 1に示した加熱装置 1における送風ファン 15 (図 1参照）と同様にヒータ 8による加熱が終了した直後の部材を冷却するため、ヒータ 8 の出口側の領域に対して冷却風を送るように設置されている。一方、送風ファン 15b は、歯車 10の凹部 39に保持された部材を効率的に冷却するため、歯車 10に対して 冷却風を送出ことができるように、歯車 10に向けて設置されている。このようにすれば 、より効果的に熱収縮チューブが設置された部材を冷却することができる。なお、送 風ファン 15a、 15bの配置は、上記のようにヒータ 8の出口側および歯車 10へ冷却風 を送出することができれば、図 9に示した配置以外の配置であってもよい。  The heating device 1 shown in FIG. 9 basically has the same structure as the heating device 1 shown in FIGS. 1 to 3, except that two blower fans 15a and 15b are installed in the lower housing 2. Is different. That is, the blower fan 15a cools the member immediately after heating by the heater 8 in the same manner as the blower fan 15 (see FIG. 1) in the heating device 1 shown in FIG. It is installed to send cooling air to it. On the other hand, the blower fan 15b is installed toward the gear 10 so that the cooling air can be sent out to the gear 10 in order to efficiently cool the member held in the recess 39 of the gear 10. In this way, the member in which the heat shrinkable tube is installed can be cooled more effectively. The arrangement of the air supply fans 15a and 15b may be other than the arrangement shown in FIG. 9 as long as the cooling air can be sent to the outlet side of the heater 8 and the gear 10.
[0040] 次に、図 10を参照して、図 1〜図 3に示した加熱装置の第 5の変形例を説明する。  Next, a fifth modification of the heating apparatus shown in FIGS. 1 to 3 will be described with reference to FIG.
図 10に示した加熱装置 1は、基本的には図 1〜図 3に示した加熱装置 1と同様の構 造を備える力 送風ファン 15の位置および導風板 28が設置されている点が異なって いる。すなわち、図 10に示した加熱装置 1では、下部筐体 2に送風ファン 15が設置さ れている。送風ファン 15はヒータ 8の出口側の領域に向けて冷却風を送出できるよう に、上方に（上ベルト 5および下ベルト 6に）向けて設置されている。この送風ファン 15 の正面に（送風ファン 15と下ベルト 6との間に）、冷却風の一部を歯車 10に向けて流 すことができるように、導風板 28が設置されている。この導風板 28は、送風ファン 15 の正面力も歯車 10に向けて延びる板状の部材である。このようにすれば、送風ファン 15から送出される冷却風を、上ベルト 5および下ベルト 6に保持された部材を冷却す るための冷却風と、歯車 10の凹部 39に保持された部材を冷却するための冷却風と の 2つに分けることができる。  The heating device 1 shown in FIG. 10 basically has the same structure as that of the heating device 1 shown in FIGS. 1 to 3, but the position of the blower fan 15 and the baffle plate 28 are installed. It is different. That is, in the heating device 1 shown in FIG. 10, the blower fan 15 is installed in the lower housing 2. The blower fan 15 is installed upward (to the upper belt 5 and the lower belt 6) so that the cooling air can be sent to the region on the outlet side of the heater 8. An air guide plate 28 is installed in front of the blower fan 15 (between the blower fan 15 and the lower belt 6) so that a part of the cooling air can flow toward the gear 10. The air guide plate 28 is a plate-like member that also has the front force of the blower fan 15 extending toward the gear 10. In this way, the cooling air sent from the blower fan 15 is cooled with the cooling air for cooling the members held by the upper belt 5 and the lower belt 6 and the member held by the recess 39 of the gear 10. It can be divided into two types: cooling air for cooling.
[0041] 次に、図 11を参照して、図 1〜図 3に示した加熱装置の第 6の変形例を説明する。  Next, a sixth modification of the heating device shown in FIGS. 1 to 3 will be described with reference to FIG.
図 11に示した加熱装置 1は、基本的には図 1〜図 3に示した加熱装置 1と同様の構 造を備えるが、歯車 30の形状が図 1に示した加熱装置 1とは異なっている。すなわち 、図 11に示した加熱装置 1における歯車 30では、部材を凹部 39に保持した状態で 冷却するときの歯車 30の進行方向（矢印 20で示す方向）側の凹部 39の側壁が、凹 部 39の上部側力も底部側に向けて進行方向側に後退しているオーバーハング部 40 を有している。このようにすれば、このオーバーハング部 40に部材が保持されること により、図 1に示した加熱装置 1の歯車 10に比べて、より長い時間部材を歯車 30の 凹部 39に保持し続けることができる。この結果、部材の冷却時間をより長くすることが できる。 The heating device 1 shown in FIG. 11 basically has the same structure as the heating device 1 shown in FIGS. 1 to 3, but the shape of the gear 30 is different from that of the heating device 1 shown in FIG. ing. Ie In the gear 30 in the heating device 1 shown in FIG. 11, the side wall of the recess 39 on the side of the traveling direction (direction indicated by the arrow 20) of the gear 30 when the member is cooled with the member held in the recess 39 is the recess 39 The upper side force of the upper side also has an overhang portion 40 that is retracted in the direction of travel toward the bottom side. In this way, by holding the member in the overhang portion 40, the member can be held in the recess 39 of the gear 30 for a longer time than the gear 10 of the heating device 1 shown in FIG. Can do. As a result, the cooling time of the member can be made longer.
[0042] (実施の形態 2)  [0042] (Embodiment 2)
図 12を参照して、本発明による加熱装置の実施の形態 2を説明する。  A second embodiment of the heating device according to the present invention will be described with reference to FIG.
[0043] 図 12は、加熱部がいわゆるコンベア型の構成の加熱装置に、本発明による個別冷 却部としての歯車 10を適用したものを示している。具体的には、加熱装置 1は、熱収 縮チューブが設置された複数の部材を搭載し移動させるためのコンベア 32および当 該コンベア 32に搭載された部材を加熱するためのヒータ 8とを含む加熱部 9としての コンベアユニット 34と、個別冷却部 16としての、歯車 10と当該歯車 10を回転させる ための歯車駆動部 36とを備える。歯車 10は、歯車駆動部 36から動力伝達部 12を介 して伝えられた駆動力により回転する。また、コンベア 32の出口側には、コンベア 32 上に搭載されている部材を歯車 10の凹部 39に案内するためのガイド 13が設置され ている。歯車 10およびガイド 13は、図 1などに示した加熱装置 1と同様に、コンベア 3 2の幅方向に間隔を隔ててそれぞれ 2つ配置されている。 2つの歯車 10の凹部 39に 、部材の両端部 (熱収縮チューブが設置された部分以外の部分)を保持する。  [0043] FIG. 12 shows a heating device having a heating unit having a so-called conveyor type configuration, in which the gear 10 as an individual cooling unit according to the present invention is applied. Specifically, the heating device 1 includes a conveyor 32 for mounting and moving a plurality of members on which heat-condensing tubes are installed, and a heater 8 for heating the members mounted on the conveyor 32. A conveyor unit 34 as the heating unit 9 and a gear 10 and a gear driving unit 36 for rotating the gear 10 as the individual cooling unit 16 are provided. The gear 10 is rotated by the driving force transmitted from the gear driving unit 36 via the power transmission unit 12. Further, a guide 13 for guiding a member mounted on the conveyor 32 to the concave portion 39 of the gear 10 is installed on the outlet side of the conveyor 32. Two gears 10 and guides 13 are arranged at intervals in the width direction of the conveyor 32 as in the heating device 1 shown in FIG. The recesses 39 of the two gears 10 hold both ends of the member (parts other than the part where the heat-shrinkable tube is installed).
[0044] このような構成の加熱装置 1においても、コンベア 32上に搭載され、コンベアュ-ッ ト 34において加熱された部材を、このコンベアユニット 34の出口側で歯車 10の凹部 39にそれぞれ個別に保持することができる。そして、当該部材を個別に歯車 10の凹 部に保持した状態で、歯車 10が所定の回転速度で回転することにより、部材を十分 冷却するための時間を確保することができる。また、図 1〜図 11に示した加熱装置 1 と同様に、コンベア 32での部材の搬送速度に整合するように、歯車 10の回転速度を 調整することで、歯車 10の凹部 39に確実に加熱後の部材を受入れることができる。  [0044] Also in the heating apparatus 1 having such a configuration, the members mounted on the conveyor 32 and heated in the conveyor unit 34 are individually separated into the recesses 39 of the gear 10 on the outlet side of the conveyor unit 34. Can be held. Then, with the members individually held in the concave portions of the gear 10, the gear 10 rotates at a predetermined rotation speed, so that a time for sufficiently cooling the member can be secured. Similarly to the heating device 1 shown in FIGS. 1 to 11, by adjusting the rotational speed of the gear 10 so as to match the conveying speed of the members on the conveyor 32, the concave portion 39 of the gear 10 can be reliably secured. The heated member can be received.
[0045] なお、上述した実施の形態においては、個別冷却部の構成として歯車 10を用いた ものを示したが、個別冷却部としては熱収縮チューブが設置された部材を個別に保 持して冷却することができれば任意の構成を採用することができる。たとえば、上記し た実施の形態において、歯車 10に代えて、たとえば複数のローラ間に架け渡された チェーンと、当該チェーンの外周部に所定の間隔で配置された、熱収縮チューブが 設置された部材をそれぞれ個別に保持するためのパケットが設置されたような構造を 個別冷却部として採用してもよい。あるいは、上述した実施の形態 1において、下べ ルト 6の出口側から当該下ベルト 6の下側のベルト表面に沿うように第 3のベルトを設 置し、当該第 3のベルトと下ベルト 6との間に熱収縮チューブが設置された複数の部 材を個別に保持した状態で移動させることにより、部材の冷却時間を確保してもよ ヽ In the above-described embodiment, the gear 10 is used as the configuration of the individual cooling unit. Although shown, the individual cooling section can be of any configuration as long as it can cool by separately holding the members on which the heat shrinkable tubes are installed. For example, in the above-described embodiment, instead of the gear 10, for example, a chain spanned between a plurality of rollers and a heat shrinkable tube disposed at a predetermined interval on the outer periphery of the chain are installed. A structure in which packets for individually holding the members are installed may be adopted as the individual cooling unit. Alternatively, in the first embodiment described above, the third belt is disposed along the belt surface on the lower side of the lower belt 6 from the outlet side of the lower belt 6, and the third belt and the lower belt 6 are arranged. It is possible to secure the cooling time of the parts by moving the multiple parts with the heat shrink tube between them while holding them individually.
[0046] あるいは、歯車 10に代えて、 2本の平行に延びる軸のそれぞれに、当該軸の周囲 を螺旋状に回転するように設置された螺旋板を配置し、螺旋板の凹んだ部分に部材 を個別に保持するようにしてもよい。この場合、軸を回転させることにより、凹んだ部分 に保持された部材を軸の延在方向に沿って移動させることができる。 [0046] Alternatively, instead of the gear 10, a spiral plate installed so as to rotate spirally around each of the two parallel extending shafts is arranged, and the concave portion of the spiral plate is disposed. You may make it hold | maintain a member separately. In this case, by rotating the shaft, the member held in the recessed portion can be moved along the extending direction of the shaft.
[0047] 上述した実施の形態の記載と一部重複するものもあるが、本発明の特徴的な構成 を以下に列挙する。  [0047] Although there may be some overlap with the description of the above-described embodiment, characteristic configurations of the present invention are listed below.
[0048] この発明に従った熱収縮チューブ用加熱装置としての加熱装置 1は、加熱部 9と個 別冷却部 16とを備える。加熱部 9は熱収縮チューブが設置された複数の部材を搬送 しながら加熱する。個別冷却部 16は、加熱部から搬出された複数の部材を、当該部 材のそれぞれの熱収縮チューブが互いに接触しな 、状態で保持しながら冷却する。  [0048] A heating device 1 as a heat-shrinkable tube heating device according to the present invention includes a heating unit 9 and an individual cooling unit 16. The heating unit 9 heats while conveying a plurality of members on which the heat shrinkable tubes are installed. The individual cooling unit 16 cools the plurality of members carried out of the heating unit while holding the respective members in a state where the respective heat-shrinkable tubes of the members are not in contact with each other.
[0049] この場合、加熱部 9においてたとえばヒータ 8により加熱された熱収縮チューブが独 立した状態で (他の部材と接触しな ヽ状態で)部材を保持したまま、当該部材を十分 に冷却することができる。したがって、熱収縮チューブが十分冷却されないまま他の 部材と接触することを防止できる。この結果、部材の仕上り外観や品質の劣化を抑制 することができる。  [0049] In this case, the member is sufficiently cooled while holding the member in a state where the heat shrinkable tube heated by, for example, the heater 8 is independent in the heating unit 9 (while not in contact with other members). can do. Therefore, it is possible to prevent the heat-shrinkable tube from contacting other members without being sufficiently cooled. As a result, it is possible to suppress deterioration of the finished appearance and quality of the member.
[0050] 上記加熱装置 1において、個別冷却部 16は、回転軸を中心に回転可能な回転体（ 歯車 10、 30)を含んでいてもよい。回転体 (歯車 10、 30)は、複数の個別保持部（凹 部 39)を有していてもよい。個別保持部（凹部 39)は、当該回転体 (歯車 10、 30)に おける回転軸力 見た径方向の外周部に配置されてもよい。個別保持部（凹部 39) は複数の部材を個別に保持する。 [0050] In the heating device 1, the individual cooling unit 16 may include a rotating body (the gears 10 and 30) that can rotate around the rotating shaft. The rotating body (gears 10, 30) may have a plurality of individual holding portions (concave portions 39). The individual holder (recess 39) is connected to the rotating body (gears 10 and 30). It may be arranged on the outer peripheral portion in the radial direction as seen from the rotational axial force. The individual holding portion (concave portion 39) holds a plurality of members individually.
[0051] この場合、回転体 (歯車 10、 30)の外周部に個別保持部（凹部 39)を複数配置す ることで、個別保持部を平面的に複数並べるような構成よりも個別冷却部 16のサイズ を小さくすることができる。そのため、加熱装置 1をコンパクトィ匕することができる。  [0051] In this case, by disposing a plurality of individual holding portions (concave portions 39) on the outer peripheral portion of the rotating body (gears 10 and 30), the individual cooling unit is more than a configuration in which a plurality of individual holding portions are arranged in a plane. The size of 16 can be reduced. Therefore, the heating device 1 can be made compact.
[0052] 上記加熱装置 1において、個別保持部は、回転体の径方向の外周部に設けられた 複数の凹部 39であってもよい。また、個別冷却部は歯車 10、 30を用いるものであつ てもよい。この場合、回転体の外周部に凹部を形成する、あるいは歯車 10、 30を準 備することにより、比較的簡単に個別冷却部 16を実現できる。  [0052] In the heating device 1, the individual holding portion may be a plurality of concave portions 39 provided on the outer peripheral portion in the radial direction of the rotating body. The individual cooling unit may use gears 10 and 30. In this case, the individual cooling unit 16 can be realized relatively easily by forming a recess in the outer peripheral portion of the rotating body or preparing the gears 10 and 30.
[0053] 上記加熱装置において、回転体 (歯車 10、 30)の回転速度は、加熱部 9における 複数の部材の搬送速度に応じて変更可能になっていてもよい。たとえば、図 1に示し た加熱装置 1では、モータ 3という同じ動力源により下ベルト 6と歯車 10とを回転させ ている。そのため、モータ 3の回転数を変更することで、加熱部 9における複数の部材 の搬送速度（下ベルト 6の移送速度）と歯車 10の回転速度とは一定の関係を保った 状態で変更することができる。この場合、加熱部 9から搬出される部材の搬出スピード に整合するように、回転体 (歯車 10、 30)の回転速度を変更することができる。このた め、加熱部から搬出される部材を確実に回転体の外周部に配置された個別保持部 に受入れることができる。  [0053] In the above heating device, the rotational speed of the rotating body (gears 10, 30) may be changeable according to the conveying speed of the plurality of members in the heating unit 9. For example, in the heating device 1 shown in FIG. 1, the lower belt 6 and the gear 10 are rotated by the same power source called the motor 3. Therefore, by changing the number of rotations of the motor 3, the conveyance speed (transfer speed of the lower belt 6) of the plurality of members in the heating unit 9 and the rotation speed of the gear 10 should be changed while maintaining a certain relationship. Can do. In this case, the rotational speed of the rotating body (gears 10 and 30) can be changed so as to match the carrying-out speed of the member carried out from the heating unit 9. For this reason, the member carried out from a heating part can be reliably received in the separate holding part arrange | positioned at the outer peripheral part of a rotary body.
[0054] 上記加熱装置 1において、加熱部 9における複数の部材の搬送速度に対する、回 転体 (歯車 10、 30)の回転速度の比率が変更可能になっていてもよい。たとえば、図 1におけるモータ 3から歯車 10への動力伝達部 12においてプーリとベルトを用いて いる場合には、当該プーリのサイズを変更する、あるいは図 6に示すようにモータ 3と 歯車 10とをギヤ部 25により接続する場合には、当該ギヤ部 25でのギヤ比を変更す るといったことにより、加熱部 9における部材の搬送速度（下ベルト 6の移送速度）に 対する回転体 (歯車 10、 30)の回転速度の比率を変更してもよ!/、。  [0054] In the heating device 1, the ratio of the rotational speed of the rotating body (the gears 10, 30) to the conveying speed of the plurality of members in the heating unit 9 may be changeable. For example, when a pulley and a belt are used in the power transmission unit 12 from the motor 3 to the gear 10 in FIG. 1, the size of the pulley is changed, or the motor 3 and the gear 10 are connected as shown in FIG. In the case of connection by the gear unit 25, the rotating body (gears 10, 10) for the conveying speed of the member in the heating unit 9 (the transfer speed of the lower belt 6) is changed by changing the gear ratio in the gear unit 25. 30) You can change the rotation speed ratio! /.
[0055] この場合、当該比率を変更することで、個別冷却部 16での部材の保持時間を、加 熱部 9での部材の搬送スピードと独立して変更することができる。このため、加熱部 9 での加熱条件によらず、部材を十分に冷却するための冷却時間を確保することが可 會 になる。 In this case, by changing the ratio, the holding time of the member in the individual cooling unit 16 can be changed independently of the conveying speed of the member in the heating unit 9. Therefore, it is possible to secure a cooling time for sufficiently cooling the member regardless of the heating conditions in the heating unit 9. Become 會.
[0056] 上記加熱装置 1において、個別冷却部 16は、図 7に示すように、回転体 (歯車 10、 30)における径方向の外周部に対向する位置に配置された落下防止カバーとしての カバー 27を含んで!/、てもよ!/、。  In the heating device 1, the individual cooling unit 16 is a cover as a fall prevention cover disposed at a position facing the outer peripheral portion in the radial direction of the rotating body (gears 10 and 30) as shown in FIG. Including 27! /!
[0057] この場合、カバー 27が配置された部分では、個別冷却部 16の個別保持部（凹部 3 9)から部材が落下することを防ぐことが出来るので、凹部 39に部材が保持されてい る時間（つまり冷却時間）をより長くすることが出来る。  [0057] In this case, in the portion where the cover 27 is disposed, the member can be prevented from dropping from the individual holding portion (the concave portion 39) of the individual cooling unit 16, and thus the member is held in the concave portion 39. The time (that is, the cooling time) can be made longer.
[0058] 上記加熱装置 1において、個別保持部としての凹部 39は、図 11に示すように、回 転体 (歯車 30)の外周部にぉ 、て、歯車 30の回転方向に沿って並ぶように形成され た、複数の部材を個別に保持する凹部 39であってもよい。凹部 39において、部材を 冷却するときの回転方向（矢印 20で示される方向）側の側壁は、凹部 39の上端側か ら底部側に向力 につれて歯車 30の回転方向側に壁面の位置が後退しているォー バーハング部 40を含んで!/、てもよ!/、。  [0058] In the heating device 1, the recesses 39 as the individual holding portions are arranged along the rotation direction of the gear 30 over the outer peripheral portion of the rotating body (the gear 30) as shown in FIG. It is also possible to form the recess 39 that holds a plurality of members individually. In the recess 39, the wall on the side of the rotation direction (direction indicated by the arrow 20) when cooling the member is moved backward from the upper end side of the recess 39 toward the bottom side as the wall surface moves toward the rotation direction side of the gear 30. Including the overhanging section 40! /!
[0059] この場合、歯車 30が回転することにより凹部 39の上端側が下向きになる場合に、 オーバーハング部 40が形成されていない場合より、部材が凹部 39のオーバーハン グ部 40によって保持されることで、部材が凹部 39に保持されている時間をより長くす ることが出来る。このため、歯車 30の回転速度を変更することなぐ個別冷却部 16で の部材の冷却時間をより長くすることが出来る。  [0059] In this case, when the upper end side of the concave portion 39 faces downward due to the rotation of the gear 30, the member is held by the overhanging portion 40 of the concave portion 39 as compared with the case where the overhang portion 40 is not formed. As a result, the time during which the member is held in the recess 39 can be made longer. For this reason, the cooling time of the member in the individual cooling section 16 without changing the rotation speed of the gear 30 can be further increased.
[0060] 上記加熱装置 1は、図 8〜図 10などに示すように、個別冷却部 16に冷却媒体 (冷 却風）を供給する冷却部材 (送風ファン 15、 15b)をさらに備えていてもよい。この場 合、個別冷却部 16での部材の冷却をより効率的に行なうことができる。  [0060] As shown in Figs. 8 to 10 and the like, the heating device 1 may further include cooling members (blower fans 15 and 15b) for supplying a cooling medium (cooling air) to the individual cooling unit 16. Good. In this case, the cooling of the member in the individual cooling unit 16 can be performed more efficiently.
[0061] 上記加熱装置 1において、上述のように冷却媒体は冷却風であり、冷却部材は送 風ファン 15、 15bであってもよい。図 10に示すように、送風ファン 15の送風口側には 、送風ファン 15から送出される冷却風の向きを個別冷却部 16に向けるための導風部 材としての導風板 28が配置されていてもよい。また、送風ファン 15は、個別冷却部 1 6に保持される前の部材に冷却風を供給してもよい。  [0061] In the heating apparatus 1, the cooling medium may be cooling air as described above, and the cooling member may be the air supply fans 15 and 15b. As shown in FIG. 10, an air guide plate 28 as an air guide member for directing the cooling air sent from the air fan 15 toward the individual cooling unit 16 is disposed on the air outlet side of the air fan 15. It may be. Further, the blower fan 15 may supply cooling air to the member before being held by the individual cooling unit 16.
[0062] この場合、個別冷却部 16に保持される前の部材の冷却と、個別冷却部 16に保持さ れた後の部材の冷却とを、同じ送風ファン 15により行なうことができる。したがって、 個別冷却部 16に保持される前の部材の冷却と、個別冷却部 16に保持された後の部 材の冷却とについて、それぞれ別の送風ファンを準備する場合より、加熱装置 1の装 置構成を簡略ィ匕できる。なお、図 9に示すように、個別冷却部 16に保持される前の部 材に冷却風を供給するための送風ファン 15aと、個別冷却部 16へ冷却風を供給する 送風ファン 15bという別個の送風ファンを配置することもできる。この場合、個別冷却 部 16への冷却風の供給と、個別冷却部 16に保持される前の部材に対する冷却風の 供給とを独立して制御することができる。 In this case, the cooling of the member before being held by the individual cooling unit 16 and the cooling of the member after being held by the individual cooling unit 16 can be performed by the same blower fan 15. Therefore, Compared to the case of preparing separate blower fans for the cooling of the parts before being held by the individual cooling unit 16 and the cooling of the parts after being held by the individual cooling unit 16, the configuration of the heating device 1 Can be simplified. In addition, as shown in FIG. 9, the blower fan 15a for supplying the cooling air to the parts before being held by the individual cooling unit 16 and the blower fan 15b for supplying the cooling air to the individual cooling unit 16 are separately provided. A blower fan can also be arranged. In this case, the supply of the cooling air to the individual cooling unit 16 and the supply of the cooling air to the member before being held by the individual cooling unit 16 can be controlled independently.
[0063] 上記加熱装置 1において、加熱部 9は、部材を加熱するためのヒータ 8と、ヒータ 8の 温度を測定するための測温部材 (熱電対 24)とを含んで 、てもよ 、。上記加熱装置 1 は、熱電対 24からヒータ 8の温度の測定データが入力される制御部（制御装置 22)を 備えていてもよい。制御装置 22は、図 5に示すように、測定データに基づいてヒータ 8 の温度が予め設定された設定温度範囲を外れたと判断したときに、加熱部 9におい て複数の部材の搬送方向を加熱するときの方向（矢印 19に示す方向）と逆方向に変 更してちよい。 [0063] In the heating device 1, the heating unit 9 may include a heater 8 for heating the member and a temperature measuring member (thermocouple 24) for measuring the temperature of the heater 8. . The heating device 1 may include a control unit (control device 22) to which measurement data of the temperature of the heater 8 is input from the thermocouple 24. As shown in FIG. 5, the control device 22 heats the conveying direction of the plurality of members in the heating unit 9 when it determines that the temperature of the heater 8 is out of the preset temperature range based on the measurement data. The direction may be changed in the opposite direction (direction indicated by arrow 19).
[0064] この場合、加熱部 9のヒータ 8の温度が設定温度範囲を外れた異常状態で、部材が 加熱装置 1に投入されることを防止できる。このため、不良品の発生確率を抑制でき る。  [0064] In this case, it is possible to prevent the member from being put into the heating device 1 in an abnormal state where the temperature of the heater 8 of the heating unit 9 is out of the set temperature range. For this reason, the probability of occurrence of defective products can be suppressed.
[0065] 上記加熱装置 1は、加熱部 9の加熱条件を報知するための報知部材 (表示ライト 17 )をさらに備えていてもよい。  The heating device 1 may further include a notification member (display light 17) for notifying the heating condition of the heating unit 9.
[0066] 上記加熱装置 1において、加熱部 9は、部材を加熱するためのヒータ 8と、ヒータ 8の 温度を測定するための測温部材 (熱電対 24)とを含んで 、てもよ 、。上記加熱装置 1 は、制御部 (制御装置 22)と報知部材 (表示ライト 17)とを備えていてもよい。制御装 置 22には、熱電対 24からヒータ 8の温度の測定データが入力されてもよい。図 4に示 すような制御を行なうことにより、表示ライト 17は、制御装置 22により制御されることに より測定データに基づ 、てヒータ 8の温度状態を報知してもよ 、。  [0066] In the heating device 1, the heating unit 9 may include a heater 8 for heating the member and a temperature measuring member (thermocouple 24) for measuring the temperature of the heater 8. . The heating device 1 may include a control unit (control device 22) and a notification member (display light 17). Measurement data of the temperature of the heater 8 may be input from the thermocouple 24 to the control device 22. By performing the control as shown in FIG. 4, the display light 17 may be informed of the temperature state of the heater 8 based on the measurement data under the control of the control device 22.
[0067] この場合、加熱装置 1を操作するオペレータなどに、表示ライト 17を用いて加熱部 9 の条件を確実に知らせることができる。したがって、オペレータによる加熱装置 1の誤 操作などの可能性を低減できる。 [0068] 今回開示された実施の形態はすべての点で例示であって制限的なものではないと 考えられるべきである。本発明の範囲は上記した説明ではなくて請求の範囲によって 示され、請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが 意図される。 In this case, the operator operating the heating apparatus 1 can be informed of the conditions of the heating unit 9 by using the display light 17 with certainty. Therefore, the possibility of erroneous operation of the heating device 1 by the operator can be reduced. [0068] It should be considered that the embodiments disclosed herein are illustrative and non-restrictive in every respect.
