本発明は、被成形体を加熱炉内で停止させないで部分加
熱することが出来る被成形体の局部加熱装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a local heating device for a molded object that can partially heat the molded object without stopping the molded object in a heating furnace.
従来、硝子板等の被成形体を曲げ成形する場合、被成形
体を加熱炉に搬入して曲げ成形が可能な温度まで加熱し
た後、被成形の自重によって及び/又はプレス押し型で
被成形体を押圧して被成形体の曲げ成形を行うことが多
い。Conventionally, when bending an object to be formed such as a glass plate, the object to be formed is brought into a heating furnace and heated to a temperature that allows bending, and then the object is formed by its own weight and/or with a press die. The object to be formed is often bent and formed by pressing the object.
この場合の加熱方法は加熱炉の種類で二つの方法に分け
られる。一つは加熱炉が吊プレス炉や重力曲げ炉等の場
合で、これらの炉は被成形体を炉内に停止させることが
出来るので、被成形体を停止して被成形体の曲げ部のみ
を局部加熱ヒータにより任意に部分加熱することが出来
る。The heating method in this case can be divided into two methods depending on the type of heating furnace. One is when the heating furnace is a hanging press furnace or a gravity bending furnace.These furnaces allow the object to be formed to be stopped in the furnace, so the object to be formed is stopped and only the bent part of the object to be formed is removed. can be partially heated as desired by a local heater.
他の一つは加熱炉がローラハース炉やエアーフオーム炉
等の場合で、こられの炉では、被成形体が常時定速で搬
送されているので被成形体を停止することが出来ない。The other case is when the heating furnace is a roller hearth furnace, an air form furnace, etc. In these furnaces, the object to be formed is constantly being conveyed at a constant speed, so it is not possible to stop the object to be formed.
従って、被成形体を搬送しながら加熱するので曲げ部の
みならず被成形体の全体を加熱することが多く、特に被
成形体の搬送方向に温度分布をつげることは極めて困難
であった。Therefore, since the object to be formed is heated while being conveyed, not only the bent portion but also the entire object to be formed is often heated, and it has been extremely difficult to narrow the temperature distribution, particularly in the direction of conveyance of the object.
(発明が解決しようする課題〕
前述したようにローラーハース炉やエアーフオーム炉で
は被成形体に搬送方向にはほとんど温度差かつかflい
ため、これらの炉内で加熱した後、自重曲げ又はプレス
押し型による曲げ成形をする際、特に深曲げ線が炉の搬
送方向とほぼ垂直方向にあるときは、十分な成形性が得
られないという問題がある。(Problems to be Solved by the Invention) As mentioned above, in roller hearth furnaces and air form furnaces, there is almost no temperature difference and slight temperature difference in the conveyance direction of the to-be-formed object. When bending with a mold, there is a problem that sufficient formability cannot be obtained, especially when the deep bend line is substantially perpendicular to the direction of conveyance in the furnace.
本発明はこのような事情に鑑みてなされたもので、被成

に送る制御子役とを有することを特徴とする。In order to achieve the above object, the present invention provides a heating device for heating and bending a molded object, which comprises: a heating furnace; a conveying means for transporting the molded object in the heating furnace; at least one auxiliary heating means that is movable up and down in the heating furnace and can be brought close to the object to be formed;
A driving means for raising and lowering the auxiliary heating means, a detecting means for detecting that the object to be molded conveyed in the heating furnace has reached a predetermined position, and a detection signal of the detecting means and a detection signal of the conveying means. By knowing the amount of movement of the molded object from the conveyance speed of the molded object, it is possible to know when the locally heated portion of the molded object reaches the lower part of the auxiliary heating means, and control to lower the auxiliary heating means by the drive means based on this information. It is characterized in that it has a control child actor that sends a signal to the driving means.

When the deep bending portion reaches below the auxiliary heating means, the second driving means is driven to place the auxiliary heating means in a position close to the object to be formed, thereby heating the deep bending portion of the object to be formed. Once the deep bending portion of the object to be formed has been heated, the second drive means is driven to position the auxiliary force means away from the object to be formed.
このようにして、被成形体の搬送中に被成形体の曲げ部
を局部加熱することが出来る。In this way, the bent portion of the object to be formed can be locally heated during transportation of the object to be formed.

6 rotates in the direction of the arrow, rollers 28A, 28A...
rotates clockwise, and the rollers 28A, 28Δ...
The upper glass plate 30 is conveyed in the direction of arrow B. The transported glass plate 30 enters the heating furnace 35, and as the glass plate 30 is further transported, the tip 30C of the glass plate 30 enters between the emitter 32 and the light receiver 34, so a change occurs in the amount of light received by the light receiver 34, and the cable 5
The signal is transmitted to the control unit via 2. When the signal is transmitted to the control unit 15, the control unit 15 counts the number of pulses output from the pulse generator 16A of the pulse motor 16 via the cable 50, and the counted pulse number is the first
When the set position is reached, a signal for normal rotation of the servo motor 44 is transmitted from the control section 15 to the servo motor 44 via the cable 54. Therefore, the servo motor 44 rotates in the normal direction, causing the rotating shaft 48 screwed to the hanging rod 46 to rotate in the normal direction, so that the heater 42 descends together with the hanging rod 46.
When the deep bent portion 30A of the glass plate 30 passes below the auxiliary heating means Y4, the heater 42
Close to A. At the same time, control cable 56 from 115
A signal is transmitted to the servo motor 16 via the servo motor 16, and the rotational speed of the servo motor 16 is slowed down, so that the moving speed of the glass plate 30 is also slowed down.

When the deep bending portion 30A has finished passing under the heater 42, the servo motor 44 is reversed and the heater 42 is vertically raised. At the same time, control i! The output of the signal transmitted from the LLN 13 to the servo motor 16 via the cable 56 is stopped, and the rotational speed of the servo motor 16 is returned to the normal speed.
