【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は、自動車の塗装面など加温を必要とするさいに使用される電気式赤外 線加熱装置に関する。 The present invention relates to an electric infrared heating device used when heating a painted surface of an automobile or the like.

【0002】[0002]

【従来の技術】[Prior art]

複数の電熱棒を赤外線反射板の前面に設け、電熱棒から発せられる赤外線を直 接に或いは反射板で反射させて塗装面などに達せしめるものとなされた電気式赤 外線加熱機は既に存在している。 There is already an electric red line heating machine that is provided with a plurality of heating rods in front of an infrared reflecting plate and that can direct the infrared rays emitted from the heating rods directly or by the reflecting plate to reach a coated surface. ing.

【0003】 この加熱機の使用にさいしては、一般に、乾燥させるべき塗装面の温度が一定 温度、例えば摂氏60度より高くならないように塗装面から十分な距離、例えば 少なくとも1m程度以上は離して位置させ、長い時間(凡そ1時間程度)をかけ てこれを乾燥させるようにしている。When using this heating device, generally, a sufficient distance, for example, at least about 1 m or more is separated from the coated surface so that the temperature of the coated surface to be dried does not exceed a certain temperature, for example, 60 degrees Celsius. It is placed and dried for a long time (about 1 hour).

【0004】[0004]

【考案が解決しようとする課題】[Problems to be solved by the device]

上記したように従来の加熱機では塗装面の過度な温度上昇を避けるために塗装 面との距離を十分に確保することが必要となるが、作業場によってはスペース上 の制約からそれができないことがある。 As described above, it is necessary to secure a sufficient distance between the conventional heating machine and the painted surface in order to avoid an excessive temperature rise on the painted surface, but this cannot be done due to space restrictions in some workplaces. is there.

【0005】 また加熱機を塗装面から十分に離してその加熱を行うと、塗装面の温度が上昇 し平衡状態となるまでの時間が長くかかり、迅速な処理が行えないのである。Further, if the heater is heated sufficiently away from the coated surface to heat the coated surface, it takes a long time for the temperature of the coated surface to rise to reach an equilibrium state, and rapid processing cannot be performed.

【0006】 これを解消するには加熱機を塗装面に出来るだけ近づけるようにすることが考 えられるが、このようにすると塗装面が過度に温度上昇する虞があり、このため 作業者が常に加熱機のそばに付いて塗装面に手をかざしての温度を感知しながら 加熱機との関係位置を適宜移動させるなどして細かく温度管理を行うことが必要 となる。In order to solve this, it is conceivable to bring the heater close to the painted surface as much as possible. However, doing so may raise the temperature of the painted surface excessively. It is necessary to perform detailed temperature control by moving the relative position to the heating device while detecting the temperature by holding the hand near the heating device and touching the painted surface.

【0007】 本考案は斯かる問題点を解消し合理的な塗装面の乾燥を図り得るものとした電 気式赤外線加熱装置を提供することを目的とする。An object of the present invention is to provide an electric infrared heating device which solves such a problem and can reasonably dry a coated surface.

【0008】[0008]

【課題を解決するための手段】[Means for Solving the Problems]

上記目的を達成するため本考案では、自動車の塗装面などに赤外線を放射する ものとした電気式赤外線加熱機の電力供給部に同加熱機への電力供給を制御する ための制御装置を組み込み、この制御装置は塗装面などの被加温箇所の温度を検 出するものとしたセンサから発出される信号が入力されて同箇所の温度を任意な 一定値に保持するように作動する構成となす。 In order to achieve the above object, in the present invention, a control device for controlling the power supply to the electric infrared heating machine that radiates infrared rays to the painted surface of an automobile is installed in the power supply section. This control device is configured to operate so as to receive the signal emitted from the sensor that detects the temperature of the heated area such as the painted surface and maintain the temperature of the same area at an arbitrary constant value. .

【0009】 このさい、電気式赤外線加熱機への電力供給を任意に設定された一定時間の後 に自動的に停止させるためのタイマを設けるのがよい。At this time, it is preferable to provide a timer for automatically stopping the power supply to the electric infrared heater after a predetermined time set arbitrarily.

【0010】[0010]

【作用】[Action]

制御装置は塗装面などの温度をセンサで検出し、この検出信号に関連して加熱 機への電力供給を制御するため、加熱機は塗装面との距離が短くてもこれを過度 に加熱することはなく任意な一定温度に加温し保持するものとなる。このことは 本考案の加熱装置を被加温面に対し最小限の位置間隔で不都合なく使用し得るも のとなし、また可及的な短時間に塗装面を必要温度に上昇させ、あとこの温度を 適宜保持し得るものとなす。 Since the control device detects the temperature of the painted surface with a sensor and controls the power supply to the heating machine in relation to this detection signal, the heating machine heats it excessively even if the distance to the painted surface is short. No matter what, it will be heated and maintained at an arbitrary constant temperature. This means that the heating device of the present invention can be used without inconvenience with respect to the surface to be heated with a minimum distance between positions, and the surface to be coated is heated to the required temperature in the shortest possible time. The temperature shall be maintained appropriately.

【実施例】【Example】

図1は本考案に係る電気式赤外線加熱装置の一実施例を示す図、図2は同加熱 装置の電気系統の概要を示す説明図である。 FIG. 1 is a diagram showing an embodiment of an electric infrared heating device according to the present invention, and FIG. 2 is an explanatory diagram showing an outline of an electric system of the heating device.

【0012】 図において、1は電気式赤外線加熱機で、具体的には赤外線反射板2の前面に 沿わせて赤外線発生用電熱棒3を水平状に並設してなる赤外線発生部4と、これ を支えるためのキャスター付支持脚5と、前記電熱棒3・・・に電力を供給する ための電力供給部6からなる。このさい電力供給部6は赤外線発生部4から延出 された電気コード6aの先端に電力供給用のプラグ6bを付設したものとなして ある。In the figure, reference numeral 1 is an electric infrared heater, and specifically, an infrared generating section 4 in which infrared heating electric heating rods 3 are horizontally arranged along a front surface of an infrared reflecting plate 2, It comprises a support leg 5 with casters for supporting this, and an electric power supply unit 6 for supplying electric power to the electric heating rods 3 ... In this case, the power supply unit 6 is configured such that a power supply plug 6b is attached to the tip of an electric cord 6a extended from the infrared generation unit 4.

【0013】 前記電力供給部6には同加熱機1への電力供給を制御するための制御装置7を 組み込むのであって、具体的には次のようになす。A control device 7 for controlling power supply to the heating machine 1 is incorporated in the power supply unit 6, and specifically, the following is performed.

【0014】 即ち、持運び自在な箱体8を形成し、これに電磁開閉器9、温度調整回路部1 0、温度設定ダイヤル10a、タイマ部11、時間設定ダイヤル11a、電源ラ ンプ12、出力用コンセント13、センサ入力用雌コネクタ14aを設けると共 に箱体8からは電気コード15を延出させてその先端に電源プラグ16を付設す る。そして、コンセント13には前記プラグ6bを差し込み、雌コネクタ14a には加熱機1から赤外線を放射される被加温体の温度を検出するための無接触式 センサ17と接続された雄コネクタ14bを差し込むようになす。That is, a portable box body 8 is formed, on which an electromagnetic switch 9, a temperature adjusting circuit section 10, a temperature setting dial 10a, a timer section 11, a time setting dial 11a, a power source lamp 12, an output. An electrical outlet 15 and a female connector for sensor input 14a are provided, and an electric cord 15 is extended from the box body 8 and a power plug 16 is attached to the tip thereof. Then, the plug 6b is inserted into the outlet 13, and the female connector 14a is provided with a male connector 14b connected to a contactless sensor 17 for detecting the temperature of a heated object radiated with infrared rays from the heater 1. Make it plug in.

【0015】 このさい、電磁開閉器9は電源プラグ16から供給された電力を断続するもの となし、温度調整回路部10は温度設定ダイヤル10aで任意な基準温度を設定 され、この基準温度と無接触式センサ17からの入力信号とに関連して電磁開閉 器9を適宜に開閉作動させるものとなし、タイマ部11は時間設定ダイヤル11 aで任意に設定された一定時間が経過すると自動的に電磁開閉器9を開放させる ものとなし、さらに電源ランプ12は温度調整回路部10に電力が供給されてい るときにのみ点灯するものとなしてある。At this time, the electromagnetic switch 9 interrupts the power supplied from the power plug 16, and the temperature adjusting circuit unit 10 sets an arbitrary reference temperature with the temperature setting dial 10a. It is assumed that the electromagnetic switch 9 is appropriately opened / closed in association with the input signal from the contact type sensor 17, and the timer unit 11 automatically operates after a certain period of time arbitrarily set by the time setting dial 11a. The electromagnetic switch 9 is not opened, and the power lamp 12 is only turned on when power is being supplied to the temperature adjusting circuit section 10.

【0016】 しかして無接触式センサ17は電熱機1の放射する赤外線を被加温体の位置で 直接に受けるものとした直接型のものであっても或いは被加温体で反射された後 の赤外線を受けるものとした間接型のものであってもよい。However, the contactless sensor 17 may be a direct type sensor that directly receives the infrared rays emitted from the electric heater 1 at the position of the object to be heated or after being reflected by the object to be heated. It may be an indirect type that receives infrared rays.

【0017】 直接型のものを使用するさいは例えば図1に示すように伸縮操作自在部位18 aの形成された支持棒装置18を介するなどしてセンサ本体17aを赤外線発生 部4の前面中央箇所に位置させるようになす。When the direct type is used, for example, as shown in FIG. 1, the sensor main body 17 a is connected to the central portion of the front surface of the infrared ray generating section 4 through a support rod device 18 on which an extendable and retractable portion 18 a is formed. To position it.

【0018】 一方、間接型のものを使用するさいは例えば同図に仮想線で示すようにセンサ 本体17bを反射板2の背後に位置させると共に、反射板2に設けた透孔2aを 通じて被加温体の反射した赤外線を検出するようになす。On the other hand, when the indirect type is used, for example, the sensor main body 17b is located behind the reflection plate 2 as shown by a phantom line in the figure, and the through hole 2a provided in the reflection plate 2 is passed through. The infrared rays reflected by the object to be heated are detected.

【0019】 上記の如く構成した本考案装置の使用例並びにその作用を説明すると、例えば 自動車を塗装した直後、被加温体としての塗装面に赤外線を放射するように加熱 機1を位置させるなどして所要の準備をする。An example of the use of the device of the present invention configured as described above and its operation will be described. For example, immediately after painting an automobile, the heating device 1 is positioned so as to radiate infrared rays on the coated surface as a heated body. And make the necessary preparations.

【0020】 このさい塗装面と加熱機の距離は従来よりも短い寸法、例えば30cm程度の 距離に設定するようになす。The distance between the coated surface and the heater is set to a shorter dimension than the conventional one, for example, a distance of about 30 cm.

【0021】 また無接触式センサ17として直接型のものを使用するときは、作業者は伸縮 操作自在部位18の長さを調整することにより、加熱機1の赤外線発生部4とセ ンサ本体17aとの距離を赤外線発生部4と塗装面との距離とほぼ同一となるよ うに調整する。これによりセンサ本体17aは加熱機1の放射する赤外線を直接 に受けて塗装面の温度を判断し得るものとなる。When a direct type sensor is used as the non-contact type sensor 17, the operator adjusts the length of the expandable / contractible portion 18 so that the infrared ray generating section 4 of the heater 1 and the sensor body 17a. Is adjusted so that it is almost the same as the distance between the infrared ray generating section 4 and the painted surface. As a result, the sensor body 17a can directly receive the infrared rays radiated by the heater 1 to judge the temperature of the coated surface.

【0022】 一方、無接触式センサとして間接型のものを使用するときは、センサ本体17 bと塗装面との距離は加熱機1の設置と同時に必然的に確定するので、これの位 置調整は不要となる。On the other hand, when an indirect sensor is used as the non-contact sensor, the distance between the sensor main body 17b and the painted surface is inevitably determined at the same time as the heater 1 is installed. Is unnecessary.

【0023】 さらに塗装面の予定加熱温度を温度設定ダイヤル10aの操作により塗装面の 塗料などに応じた適当な一定温度(例えば摂氏60度など)に設定するほか、必 要に応じて塗装面の乾燥に要すると思われる時間(例えば40分など)を時間設 定ダイヤル11aで設定する。Further, the planned heating temperature of the coated surface is set to an appropriate constant temperature (for example, 60 degrees Celsius) according to the paint on the coated surface by operating the temperature setting dial 10a, and the coated surface is heated as necessary. A time (for example, 40 minutes) considered to be necessary for drying is set by the time setting dial 11a.

【0024】 かくして装置を作動状態となすと、加熱機1は赤外線を放射して塗装面を近接 位置から加熱するものとなり、またセンサ17は常に塗装面の温度を検出して温 度調整回路部10に信号を入力する。温度調整回路部10はセンサ17からの信 号と温度設定ダイヤル10aで設定された設定温度とを比較し、塗装面の温度が 設定温度よりも高くなったときは電磁開閉器9を開作動させ、逆に塗装面の温度 が設定温度よりも低くなったときは同開閉器9を閉作動させるようにしてON・ OFF制御を実行し、塗装面を常に一定温度、例えば摂氏60度に保持するもの となる。Thus, when the apparatus is in the operating state, the heater 1 emits infrared rays to heat the painted surface from a close position, and the sensor 17 constantly detects the temperature of the painted surface and the temperature adjusting circuit section. Input a signal to 10. The temperature adjustment circuit section 10 compares the signal from the sensor 17 with the set temperature set by the temperature setting dial 10a, and when the temperature of the coated surface becomes higher than the set temperature, the electromagnetic switch 9 is opened. On the contrary, when the temperature of the coated surface becomes lower than the set temperature, the switch 9 is closed and ON / OFF control is executed to keep the coated surface at a constant temperature, for example, 60 degrees Celsius. Will be things.

【0025】 しかしてタイマ部11は加熱開始から一定時間(例えば40分)が経過したと き自動的に電磁開閉器9を開作動させ、加熱機1の作動を終了させる。なお加熱 機1を手操作で停止させることは自由である。However, the timer unit 11 automatically opens the electromagnetic switch 9 after a lapse of a certain time (for example, 40 minutes) from the start of heating and ends the operation of the heater 1. Note that the heating machine 1 can be stopped manually.

【0026】 表1はセンサ17を直接型となし、加熱機1と塗装面との距離を30cmに設 定し、温度設定ダイヤル10aの設定温度を摂氏60度として実験した場合にお ける加熱開始後の経過時間と塗装面の温度との関係を示すものであり、塗装面が 白、グレー、黒の場合の三種類について行っている。In Table 1, the sensor 17 is a direct type, the distance between the heater 1 and the painted surface is set to 30 cm, and the heating start in the case where the temperature setting dial 10a is set to 60 degrees Celsius and the heating is started. It shows the relationship between the elapsed time afterwards and the temperature of the painted surface, and it is done for three types when the painted surface is white, gray, or black.

【0027】[0027]

【表1】 [Table 1]

【0028】 また表2はセンサ17を間接型となし、これ以外は先の実験の場合と同一とな して実験した場合における加熱開始後の経過時間と塗装面の温度との関係を示す ものである。Further, Table 2 shows the relationship between the elapsed time after the start of heating and the temperature of the coated surface in the case where the sensor 17 is an indirect type and the experiment is the same as the previous experiment except that the sensor 17 is the indirect type. Is.

【0029】[0029]

【表2】 [Table 2]

【0030】 これらの表から明らかなように塗装面は加熱開始後5〜10分でほぼ予定加熱 温度に達し、以後はその温度を維持されるものとなっている。これは従来におい て予定加熱温度に達するのに要していた温度平衡化のための時間(凡そ20分程 度)と較べ、大幅な短縮となっており、乾燥作業の能率化を図らしめるものであ る。As is clear from these tables, the coated surface reaches the planned heating temperature 5 to 10 minutes after the start of heating, and the temperature is maintained thereafter. This is much shorter than the time required for temperature equilibration (about 20 minutes), which was required to reach the planned heating temperature in the past, and it helps to improve the efficiency of the drying operation. Is.

【0031】 なお、参考までに表1の実験で制御装置7を非作動状態となしたときの加熱開 始後の経過時間と塗装面の温度との関係を示すと表3のとおりである。これによ ると加熱開始後、塗装面は5〜10分で摂氏60度以上に達し、過熱状態となる ことがわかる。For reference, Table 3 shows the relationship between the elapsed time after the start of heating and the temperature of the coated surface when the control device 7 is set in the inoperative state in the experiment of Table 1. According to this, it can be seen that the coated surface reaches 60 degrees Celsius or higher in 5 to 10 minutes after the start of heating, and becomes overheated.

【考案の効果】[Effect of device]

上記の如く構成した本考案によれば、被加温体と加熱機との距離の大小に関係 なく安定した一定温度に制御されることから、加熱機を塗装面などの被加温体に 対し安心して可及的に近接位置させることができるのであり、このため塗装面な どを直ちに必要加熱温度に達せしめ、以後はその温度を効果的に維持させ得るも のとなって乾燥などの処理を迅速且つ的確に行わしめるほか、たとえ狭小な作業 場であっても何等支障なく乾燥させ得るものとなる。 本考案に於いて被加温体は塗装面に限らず、他の加熱乾燥用にも適用できる。 According to the present invention configured as described above, since the temperature is controlled to a stable constant temperature regardless of the distance between the object to be heated and the heater, the heater can be applied to the object to be heated such as a painted surface. Since it is possible to place them as close as possible to each other with peace of mind, it is possible to immediately reach the required heating temperature on the coated surface, etc., and to maintain that temperature effectively thereafter, such as drying. In addition to being able to perform quickly and accurately, it is possible to dry without any problem even in a small work space. In the present invention, the object to be heated is not limited to the painted surface but can be applied to other heating and drying.
