図１は熱処理装置の一例の構成を示す。   FIG. 1 shows an exemplary configuration of a heat treatment apparatus.

図１に示す熱処理装置１は、ワークＷを搬送し、搬送途上でワークＷを熱処理するものである。ワークＷは、図示の例では比較的長尺な棒材であるが特に限定されるものではなく、例えば管材などであってもよく、その断面形状も四角形状や円形状など種々の形状をとりえる。   The heat processing apparatus 1 shown in FIG. 1 conveys the workpiece | work W, and heat-processes the workpiece | work W in the middle of conveyance. The workpiece W is a relatively long rod in the illustrated example, but is not particularly limited. For example, the workpiece W may be a pipe or the like, and the cross-sectional shape thereof may take various shapes such as a square shape or a circular shape. Yeah.

熱処理装置１は、ワークＷを熱処理する熱処理部２と、熱処理部２にワークＷを搬入する搬入部３と、熱処理部２からワークＷを搬出する搬出部４と、熱処理部２、搬入部３、及び搬出部４の各部の動作を統括制御する制御部５とを備える。   The heat treatment apparatus 1 includes a heat treatment unit 2 that heat-treats the workpiece W, a carry-in unit 3 that carries the work W into the heat treatment unit 2, a carry-out unit 4 that carries the work W out of the heat treatment unit 2, a heat treatment unit 2, and a carry-in unit 3. And a control unit 5 that performs overall control of the operation of each part of the carry-out unit 4.

熱処理部２、搬入部３、及び搬出部４には、回転軸が水平に配され、ワークＷの搬送経路Ｌに沿って並列された複数の搬送ローラ１０と、回転軸が鉛直に配され、搬送経路Ｌに沿って搬送経路Ｌの水平方向片側に並列された複数のガイドローラ１１と、がそれぞれ設けられている。   In the heat treatment unit 2, the carry-in unit 3, and the carry-out unit 4, the rotation shaft is arranged horizontally, the plurality of conveyance rollers 10 arranged in parallel along the conveyance path L of the workpiece W, and the rotation shaft are arranged vertically, A plurality of guide rollers 11 arranged in parallel on one side in the horizontal direction of the transport path L are provided along the transport path L.

一部の搬送ローラ１０は図示しない搬送ローラ駆動部によって回転駆動され、これらの搬送ローラ１０の転動によって、ワークＷは、搬送経路Ｌに沿って搬送される。   Some of the transport rollers 10 are rotationally driven by a transport roller driving unit (not shown), and the workpiece W is transported along the transport path L by the rolling of the transport rollers 10.

図２は、搬入部３の構成を示す。   FIG. 2 shows the configuration of the carry-in unit 3.

搬入部３には、搬送経路ＬにワークＷを順次供給する供給装置１２が設けられている。供給装置１２は、ガイドローラ１１が設けられている側とは反対側にあたる搬送経路Ｌの水平方向他側に配置されている。   The carry-in unit 3 is provided with a supply device 12 that sequentially supplies workpieces W to the conveyance path L. The supply device 12 is disposed on the other side in the horizontal direction of the transport path L on the side opposite to the side on which the guide roller 11 is provided.

供給装置１２は、搬送経路Ｌに沿って並列された複数のコンベアベルト１３を有する。コンベアベルト１３は、搬送経路Ｌに略直交して水平方向に延びており、間欠的に駆動される。   The supply device 12 has a plurality of conveyor belts 13 arranged in parallel along the transport path L. The conveyor belt 13 extends in a horizontal direction substantially orthogonal to the transport path L and is driven intermittently.

これらのコンベアベルト１３には、複数のワークＷが搬送経路Ｌと略平行に並置される。コンベアベルト１３の間欠駆動に伴って、ワークＷが搬入部３の搬送ローラ１０上に順次供給される。   On these conveyor belts 13, a plurality of workpieces W are juxtaposed in parallel with the transport path L. As the conveyor belt 13 is intermittently driven, the workpiece W is sequentially supplied onto the transport roller 10 of the carry-in unit 3.

搬送ローラ１０は、その回転軸が搬送経路Ｌに対して斜交するように配置されており、搬送ローラ１０の軸方向の両端部１０ａ，１０ｂのうち、ガイドローラ１１が設けられている搬送経路Ｌの水平方向片側に位置する端部１０ａは他方の端部１０ｂよりも搬送経路Ｌの上流側に位置している。   The conveyance roller 10 is arranged so that the rotation axis thereof is oblique with respect to the conveyance path L, and the conveyance path in which the guide roller 11 is provided among the axial end portions 10 a and 10 b of the conveyance roller 10. The end portion 10a located on one side in the horizontal direction of L is located on the upstream side of the transport path L with respect to the other end portion 10b.

上記のように搬送経路Ｌに対して傾斜した搬送ローラ１０によって搬送されるワークＷは、搬送ローラ１０の転動に伴い、ガイドローラ１１が設けられている搬送経路Ｌの水平方向片側に幅寄せされる。幅寄せされたワークＷは、ガイドローラ１１に接触し、ガイドローラ１１との接触を保って搬送経路Ｌに沿って搬送される。   As described above, the workpiece W transported by the transport roller 10 inclined with respect to the transport path L is brought closer to one side in the horizontal direction of the transport path L where the guide roller 11 is provided as the transport roller 10 rolls. Is done. The workpiece W that has been brought into contact with the guide roller 11 is transported along the transport path L while maintaining contact with the guide roller 11.

熱処理部２及び搬出部４においても、搬送ローラ１０は同様に搬送経路Ｌに対して傾斜して配置されており、ワークＷは、ガイドローラ１１側に幅寄せされ、ガイドローラ１１との接触を保って搬送経路Ｌに沿って搬送される。   Similarly, in the heat treatment unit 2 and the carry-out unit 4, the conveyance roller 10 is similarly inclined with respect to the conveyance path L, and the workpiece W is brought closer to the guide roller 11 side and brought into contact with the guide roller 11. It is conveyed along the conveyance path L.

このように、搬送経路Ｌに対して搬送ローラ１０を傾斜させ、搬送ローラ１０の転動に伴ってワークＷをガイドローラ１１側に幅寄せすることにより、ワークＷを自動的に搬送経路Ｌに乗せ、また、搬送経路Ｌに維持することができる。そして、ガイドローラ１１は転動可能であり、ガイドローラ１１との接触によってもワークＷの表面に擦過痕がつくことを抑制することができる。   In this way, the work roller 10 is automatically moved to the transport path L by tilting the transport roller 10 with respect to the transport path L and reducing the width of the work W toward the guide roller 11 as the transport roller 10 rolls. It can be placed and maintained on the transport path L. The guide roller 11 can roll, and the contact with the guide roller 11 can prevent the surface of the workpiece W from being scratched.

図３及び図４は、熱処理部２の構成を示す。   3 and 4 show the configuration of the heat treatment section 2.

本熱処理装置１では、熱処理部２は、ワークＷを誘導加熱するように構成されており、加熱コイル２０と、加熱コイル２０に交流電力を供給する電源部２１とを有する。   In the heat treatment apparatus 1, the heat treatment unit 2 is configured to inductively heat the workpiece W, and includes a heating coil 20 and a power supply unit 21 that supplies AC power to the heating coil 20.

ワークＷの加熱方法は炉加熱であってもよいが、炉加熱では炉の予熱が必要であり、典型的には炉は連続運転される。これに対し、誘導加熱では、炉加熱に比べて加熱立ち上がり時間が極めて短く、加熱の際に加熱コイルに電力を供給すればよいので、一般に、炉加熱に比べてエネルギ効率に優れる。   Although the method of heating the workpiece W may be furnace heating, the furnace heating requires preheating of the furnace, and typically the furnace is continuously operated. On the other hand, in induction heating, the heating rise time is extremely short compared to furnace heating, and it is sufficient to supply power to the heating coil during heating, so that it is generally more energy efficient than furnace heating.

熱処理部２にてワークＷに施される熱処理は特に限定されるものではなく、焼入れ、焼き戻し、焼鈍し、焼きならし、等を例示することができる。本熱処理装置１では、熱処理部２は、ワークＷに焼入れ及び焼き戻しを施すように構成されており、ワークＷを焼き入れ温度に加熱する第１加熱部２２と、焼入れ温度に加熱されたワークＷを冷却する冷却部２３と、冷却されたワークＷを焼き戻し温度に加熱する第２加熱部２４と、を有する。   The heat treatment applied to the workpiece W in the heat treatment section 2 is not particularly limited, and examples thereof include quenching, tempering, annealing, normalizing, and the like. In the heat treatment apparatus 1, the heat treatment unit 2 is configured to quench and temper the workpiece W, and includes a first heating unit 22 that heats the workpiece W to a quenching temperature, and a workpiece heated to the quenching temperature. It has the cooling part 23 which cools W, and the 2nd heating part 24 which heats the cooled workpiece | work W to tempering temperature.

第１加熱部２２には加熱コイル２０ａが設けられ、第２加熱部２４にもまた加熱コイル２０ｂが設けられている。加熱コイル２０ａ，２０ｂは、ワークＷの形状などに応じて適宜選択される。   The first heating unit 22 is provided with a heating coil 20a, and the second heating unit 24 is also provided with a heating coil 20b. The heating coils 20a and 20b are appropriately selected according to the shape of the workpiece W and the like.

加熱コイル２０ａ，２０ｂに交流電力が供給されると、加熱コイル２０ａ，２０ｂに対向するワークＷの被加熱部位には電磁誘導によって電流が流れ、それにより被加熱部位が加熱される。ワークＷの搬送に伴い、被加熱部位が軸方向に逐次移り、ワークＷの各部が連続的に誘導加熱される。   When AC power is supplied to the heating coils 20a and 20b, a current flows through the heated portion of the workpiece W facing the heating coils 20a and 20b by electromagnetic induction, thereby heating the heated portion. As the work W is transported, the heated portion sequentially moves in the axial direction, and each part of the work W is continuously induction-heated.

冷却部２３は、第１加熱部２２にて焼入れ温度に加熱されたワークＷに向けて、図示しない冷却液供給部から供給される冷却液を噴射し、ワークＷを冷却する。   The cooling unit 23 cools the workpiece W by injecting a coolant supplied from a coolant supply unit (not shown) toward the workpiece W heated to the quenching temperature by the first heating unit 22.

なお、熱処理部２には、鉛直方向に移動可能とされ、搬送ローラ１０との間にワークＷを挟み込む押えローラ２５が適宜設けられている。また、熱処理部２には、水平方向に移動可能とされ、ガイドローラ１１との間にワークＷを挟み込む従動側ガイドローラ２６が適宜設けられている。ワークＷは、搬送ローラ１０と押えローラ２５、また、ガイドローラ１１と従動側ガイドローラ２６とに挟まれることによって加熱による変形が抑制され、ワークＷと加熱コイル２０ａ，２０ｂとの接触が防止される。   The heat treatment unit 2 is appropriately provided with a pressing roller 25 that is movable in the vertical direction and sandwiches the workpiece W with the conveying roller 10. Further, the heat treatment section 2 is appropriately provided with a driven guide roller 26 that is movable in the horizontal direction and sandwiches the workpiece W with the guide roller 11. The workpiece W is sandwiched between the conveying roller 10 and the pressing roller 25, and between the guide roller 11 and the driven guide roller 26, so that deformation due to heating is suppressed, and contact between the workpiece W and the heating coils 20a and 20b is prevented. The

図５は、搬出部４の構成を示す。   FIG. 5 shows the configuration of the carry-out unit 4.

搬出部４には、搬出されたワークＷがストックされる取出装置３０が設けられている。取出装置３０は、ガイドローラ１１が設けられている側とは反対側にあたる搬送経路Ｌの水平方向他側に配置されている。   The unloading unit 4 is provided with an unloading device 30 in which the unloaded work W is stocked. The take-out device 30 is disposed on the other side in the horizontal direction of the transport path L, which is the side opposite to the side on which the guide roller 11 is provided.

取出装置３０は、例えば搬入部３の供給装置１２（図２参照）と同様に、搬送経路Ｌに沿って並列された複数のコンベアベルトを用い、これらのコンベアベルトにワークＷを並置させ、コンベアベルトを駆動してワークＷを取り出すように構成することができる。また、取出装置３０は、ワークＷがその自重によって滑落するシュータとして構成することもできる。   The take-out device 30 uses, for example, a plurality of conveyor belts arranged in parallel along the conveyance path L, similarly to the supply device 12 (see FIG. 2) of the carry-in unit 3, and works W are juxtaposed on these conveyor belts. It can be configured to take out the workpiece W by driving the belt. The take-out device 30 can also be configured as a shooter in which the workpiece W slides down due to its own weight.

ここで、搬出部４に設けられたガイドローラ１１は搬送経路Ｌに交差する水平方向に移動可能とされており、搬出部４には、ガイドローラ１１を移動させ、搬送されたワークＷを搬送経路Ｌから取出装置３０に向けて押し出すガイドローラ駆動部３１が設けられている。   Here, the guide roller 11 provided in the carry-out unit 4 is movable in the horizontal direction intersecting the conveyance path L, and the guide roller 11 is moved to the carry-out unit 4 to convey the conveyed work W. A guide roller drive unit 31 that pushes out from the path L toward the take-out device 30 is provided.

ガイドローラ駆動部３１は、制御部５によって制御され、制御部５は、ワークＷが搬出されたことを検知してガイドローラ駆動部３１を動作させる。ワークＷの搬出を検知する方法は特に限定されないが、例えば、搬送経路Ｌの終端に適宜なセンサを設け、ワークの先端が搬送経路Ｌの終端に達したことにより、ワークＷが搬出部４に搬出されたことを検知することができる。   The guide roller driving unit 31 is controlled by the control unit 5, and the control unit 5 detects that the workpiece W has been carried out and operates the guide roller driving unit 31. The method for detecting the unloading of the workpiece W is not particularly limited. For example, an appropriate sensor is provided at the end of the transfer path L, and the workpiece W is transferred to the unloading unit 4 when the tip of the workpiece reaches the end of the transfer path L. It can be detected that it has been carried out.

搬出部４に搬出されたワークＷは、制御部５によってガイドローラ駆動部３１が動作されてガイドローラ１１が移動されることより、自動的に搬送経路Ｌから押し出されて取出装置３０に移載される。   The work W carried out to the carry-out unit 4 is automatically pushed out of the conveyance path L and transferred to the take-out device 30 when the guide roller driving unit 31 is operated by the control unit 5 and the guide roller 11 is moved. Is done.

ここで、搬出部４に設けられたガイドローラ１１は、複数のローラ群に区分されている。図示の例では、搬送経路Ｌの終端から順に第１群１１ａ，第２群１１ｂ、第３群１１ｃに区分されている。また、ガイドローラ駆動部３１は、第１群１１ａ，第２群１１ｂ、及び第３群１１ｃを独立に、ローラ群毎に移動させることが可能に構成されている。   Here, the guide roller 11 provided in the carry-out part 4 is divided into a plurality of roller groups. In the illustrated example, the first group 11a, the second group 11b, and the third group 11c are divided in order from the end of the transport path L. The guide roller driving unit 31 is configured to be able to move the first group 11a, the second group 11b, and the third group 11c independently for each roller group.

そして、制御部５は、ワークＷの長さに応じた一部又は全部のローラ群が移動されるようにガイドローラ駆動部３１を動作させる。例えば、ワークＷの長さが第１群１１ａの区間長に収まる場合に、第１群１１ａのみ移動されてワークＷが搬送経路Ｌから押し出される。また、図５に示す例のように、ワークＷの長さが第１群１１ａの区間長を超えて第１群１１ａ及び第２群１１ｂを合わせた区間長に収まる場合には、第１群１１ａ及び第２群１１ｂが移動されてワークＷが搬送経路Ｌから押し出される。また、ワークＷの長さが第１群１１ａ及び第２群１１ｂを合わせた区間長を超える場合には、第１群１１ａ、第２群１１ｂ及び第３群１１ｃが移動されてワークＷが搬送経路Ｌから押し出される。   And the control part 5 operates the guide roller drive part 31 so that the one part or all part roller group according to the length of the workpiece | work W may be moved. For example, when the length of the workpiece W falls within the section length of the first group 11a, only the first group 11a is moved and the workpiece W is pushed out from the conveyance path L. Further, as in the example shown in FIG. 5, when the length of the workpiece W exceeds the section length of the first group 11a and falls within the section length of the first group 11a and the second group 11b, the first group 11a and the second group 11b are moved, and the workpiece W is pushed out from the conveyance path L. When the length of the work W exceeds the combined length of the first group 11a and the second group 11b, the first group 11a, the second group 11b, and the third group 11c are moved to transport the work W. It is pushed out from the path L.

ワークＷの長さは情報は、例えば作業者によって予め制御部５に入力される。また、ワークＷの存在を検出可能な適宜なセンサを第１群１１ａと第２群１１ｂとの間、及び第２群１１ｂと第３群１１ｃとの間に設け、ワークの後端が第１群１１ａ、第２群１１ｂ、第３群１１ｃのいずれの区間に位置しているかを検出し、これらのセンサの出力に基づいて、制御部５がワークＷのおおまかな長さを都度検出するようにしてもよい。   Information on the length of the workpiece W is input to the control unit 5 in advance by an operator, for example. Further, appropriate sensors capable of detecting the presence of the workpiece W are provided between the first group 11a and the second group 11b and between the second group 11b and the third group 11c, and the rear end of the workpiece is the first. It is detected in which section of the group 11a, the second group 11b, or the third group 11c, and the control unit 5 detects the approximate length of the workpiece W each time based on the outputs of these sensors. It may be.

このように、ワークＷの長さに応じた一部又は全部のローラ群を移動させることにより、ワークＷの長さにかかわらず一律に全てのガイドローラ１１を移動させる場合に比べて、エネルギ消費を削減することができる。   In this way, by moving a part or all of the roller groups according to the length of the workpiece W, energy consumption is compared to when all the guide rollers 11 are moved uniformly regardless of the length of the workpiece W. Can be reduced.

なお、上記のガイドローラ１１の区分は一例であり、熱処理装置１にて処理するワークＷの長さのバリエーションに応じて適宜設定することができる。   The above-described division of the guide roller 11 is an example, and can be set as appropriate according to variations in the length of the workpiece W to be processed by the heat treatment apparatus 1.
