  Hereinafter, an embodiment of an induction heat roller device according to the present invention will be described with reference to the drawings.

  The induction heating roller device 100 according to the present embodiment is used in, for example, a continuous heat treatment process of an object to be heated W such as a metal foil or a film. As shown in FIG. 1, a hollow cylinder provided rotatably. And a magnetic flux generating mechanism 3 as a heating mechanism accommodated in the roller main body 2.

  Journals 4 are integrally attached to both ends of the roller body 2. The journal 4 is configured such that a hollow drive shaft 41 and a flange 42 are integrally formed. The journal 4 is connected to the end surface in the axial direction of the roller body 2 so as to cover the end opening of the roller body 2. The drive shaft 41 is rotatably supported by the base 52 via a bearing 51 such as a rolling bearing. The roller body 2 is rotated by rotating the drive shaft 41 of the journal 4 with an external driving force using, for example, a motor.

  In addition, a plurality of jacket chambers 21A for enclosing a gas-liquid two-phase heat medium extending in the longitudinal direction (axial direction) are formed in the side peripheral wall 21 of the roller main body 2 with an interval in the entire circumferential direction. The ends of the plurality of jacket chambers 21A communicate with the ends of the adjacent jacket chambers 21A. The surface temperature of the roller body 2 is made uniform by the latent heat transfer of the gas-liquid two-phase heat medium sealed in the jacket chamber 21A.

  The magnetic flux generation mechanism 3 includes a cylindrical iron core 31 having a cylindrical shape, and an induction coil 32 wound around the outer peripheral surface of the cylindrical iron core 31. Support rods 6 are attached to both ends of the cylindrical iron core 31, respectively. Each of the support rods 6 is inserted into the drive shaft 41 and is rotatably supported with respect to the drive shaft 41 via a bearing 7 such as a rolling bearing. Thereby, the magnetic flux generation mechanism 3 is supported in a suspended state inside the roller body 2. Further, the rotation of the magnetic flux generation mechanism 3 is restricted between the magnetic flux generation mechanism 3 and a gantry by a rotation stopper (not shown). A lead wire L1 is connected to the induction coil 32, and an AC power supply (not shown) for applying an AC voltage is connected to the lead wire L1.

  By such a magnetic flux generation mechanism 3, an alternating magnetic flux is generated when an AC voltage is applied to the induction coil 32, and the alternating magnetic flux passes through the side peripheral wall 21 of the roller body 2. This passage generates an induced current in the roller body 2, and the roller body 2 generates Joule heat by the induced current. The roller body 2 makes the surface temperature in the axial direction of the roller body 2 uniform by means of a jacket chamber 21A provided inside.

  Thus, the induction heating roller device 100 according to the present embodiment sucks gas from the load contact area on the surface of the roller main body 2 where the workpiece W can come into contact, thereby bringing the workpiece W into close contact with the roller main body 2 and the load. It is configured such that the workpiece W can be separated from the roller main body 2 by blowing out gas from the rotation direction feed side region of the contact region. The workpiece W adsorbed on the load contact area in this way is sent along the rotation direction as the roller body 2 rotates. In addition, as gas to blow off, inert gas, such as nitrogen, argon, or helium, can be considered, for example.

  Specifically, as shown in FIGS. 1 and 2, a plurality of gas flow passages 201 provided on the side peripheral wall 21 of the roller body 2, and gas flow passages provided corresponding to the respective gas flow passages 201.

A region changing mechanism 8 that changes X1 in the circumferential direction, changes the gas flow passage 201 that blows gas out of the plurality of gas flow passages 201, and changes the gas blowing region X2 that blows gas from the vent 202 in the circumferential direction. With. Note that the gas suction region X1 and the gas blowing region X2 are located at the same position without moving in the circumferential direction regardless of the rotation of the roller body 2 when the region change mechanism 8 does not change.

  As shown in FIG. 2, the plurality of gas flow passages 201 are provided at equal intervals over the entire circumference of the side peripheral wall 21 of the roller body 2. Each gas flow passage 201 is provided so as to extend along the axial direction of the roller body 2, and allows gas to flow along the axial direction of the roller body 2. Each gas flow passage 201 extends from the axial end of the roller body 2 over the entire load contact area in the axial direction of the roller body 2.

  These gas flow passages 201 are provided at positions different from the jacket chamber 21 </ b> A provided in the side peripheral wall 21 of the roller body 2. For example, it is desirable to provide the jacket chamber 21A at the center of the adjacent gas flow passages 201 in consideration of the temperature effects of the jacket chamber 21A and the gas flow passage 201.

  In addition, as shown in FIGS. 1 and 2, each gas flow passage 201 includes a plurality of gas flow passages 201 that extend radially outward in the side peripheral wall 21 of the roller body 2 and open to the surface of the roller body 2. The vent hole 202 is formed. A plurality of vent holes 202 communicating with each gas flow passage 201 are provided, for example, at equal intervals over the entire load contact area in the axial direction of the roller body 2.

  The plurality of gas flow passages 201 are open at one end surface in the axial direction of the roller body 2, and the gas flow passages 201 communicate with a journal internal flow path 401 formed on the side peripheral wall of the journal 4. .

  As shown in FIG. 1, the journal internal flow path 401 has one end opened on the roller body side end surface of the flange 42 of the journal 4 and the other end opened on the side peripheral surface 411 of the drive shaft 41 of the journal 4. Yes. As shown in FIG. 3, the journal internal flow paths 401 are formed at equal intervals along the entire circumference of the side wall of the drive shaft 41, and are formed radially on the side wall of the flange 42.

  One end opening 401 a of the journal internal flow path 401 is configured to communicate with two gas flow passages 201 provided in the roller body 2. Specifically, as shown in FIGS. 1 and 3, a communication recess 2 </ b> M that communicates two circumferentially adjacent gas flow passages 201 is formed on one end surface in the axial direction of the roller body 2. In the state where the flange 42 of the journal 4 is connected to one end surface in the axial direction, one end opening 401a of one journal internal channel 401 is configured to be connected to the communication recess 2M. As a result, two gas flow paths 201 are connected to one journal internal flow path 401. Further, the other end opening 401b of the journal internal flow path 401 is opened outside a support portion that is rotatably supported by the machine base 52 via the bearing 51 in consideration of the installation space of the slide body 81 described later. doing. Further, the other end openings 401 b of the journal internal flow path 401 are formed at equal intervals in the circumferential direction of the drive shaft 41 and at the same position in the axial direction.

  The area changing mechanism 8 changes the journal internal flow path 401 for sucking gas and the journal internal flow path 401 for introducing gas among the plurality of journal internal flow paths 401 formed in the journal 4 as the roller body 2 rotates. By doing so, the gas flow passage 201 for sucking in the gas and the gas flow passage 201 for blowing out the gas are changed. In the present embodiment, since two adjacent gas flow paths 201 are connected to one journal internal flow path 401, the gas flow paths 201 for introducing gas in units of two are changed.

The region changing mechanism 8 sucks gas from the journal internal flow path 401 continuous in the circumferential direction or introduces gas into the journal internal flow path 401. Then, the region changing mechanism 8 of the present embodiment changes the number of journal internal flow paths 401 that are continuous in the circumferential direction, changes the gas flow path 201 for sucking gas among the plurality of gas flow paths 201, and gas suction changing the circumferential angular range theta ₁ region X1 (see FIG. 2). The region changing mechanism 8 of this embodiment is configured so as to maintain the circumferential angular range theta ₂ of the gas outlet region X2 constant.

  As a specific configuration, as shown in FIG. 1, a slide body 81 that is fixed in the circumferential direction with respect to the drive shaft 41 of the journal 4 and is slidably mounted in the axial direction, and the slide body 81 are stationary. And a moving mechanism 82 for moving in the axial direction of the drive shaft 41 with respect to the machine base 52 as a side. As shown in FIG. 1, the moving mechanism 82 is moved in the axial direction by a screw mechanism using a bolt, but may be another one using an air cylinder or the like.

  As shown in FIG. 1, the slide body 81 is connected to a gas exhaust pipe 91 connected to the suction device 9, and sucks air from the journal internal flow path 401 opened to the drive shaft 41 of the journal 4. A gas supply pipe 101 for supplying a gas from the gas source 10 is connected, and the supplied gas is introduced into a journal internal flow path 401 opened in the drive shaft 41 of the journal 4.

  Specifically, as shown in FIG. 4, the slide body 81 has a substantially cylindrical shape that is fitted with a slight backlash on the side peripheral surface of the drive shaft 41 of the journal 4, and the drive shaft is formed on the inner peripheral surface thereof. A first recessed portion 811a that forms a gas discharge space Sa and a second recessed portion 811b that forms a gas supply space Sb are formed between the outer peripheral surface of 41 and the outer peripheral surface. Note that bearings 83 are provided between the slide body 81 and the drive shaft 41 on both sides of the first recess 811a and the second recess 811b in the axial direction (see FIG. 1).

  As shown in FIG. 4, the first concave portion 811 a is formed in the circumferential direction, and an exhaust passage 812 a exhausted by the gas exhaust pipe 91 is formed on the bottom surface of the concave portion. Further, a sealing member 813 such as an O-ring is provided outside the first recess 811a in order to make the gas discharge space Sa airtight. Since the first concave portion 811a is thus formed in a predetermined angular range in the circumferential direction, the opening 401b of the journal internal channel 401 once communicated with the first concave portion 811a in a state where the journal 4 is rotating. Will continue to communicate with the recess 811 until it rotates a predetermined angle. That is, in the state where the roller body 2 is rotating, the vent 202 included in the gas suction region X1 rotates while continuously sucking the gas. Note that the opening 401b of the journal internal flow path 401 that does not communicate with the first recess 811a is covered and closed by the inner peripheral surface of the slide body 81, and gas is not sucked.

  As shown in FIG. 4, the second recess 811 b is formed in the circumferential direction, and an inflow passage 812 b into which the gas from the gas supply pipe 101 flows is formed on the bottom surface of the recess. Further, a seal member 813 such as an O-ring is provided outside the second recess 811b in order to make the gas supply space S airtight. Since the second recess 811b is thus formed in a predetermined angular range in the circumferential direction, the opening 401b of the journal internal channel 401 once communicated with the second recess 811b in a state where the journal 4 is rotating. Will continue to communicate with the second recess 811b until it rotates by a predetermined angle. That is, in the state where the roller body 2 is rotating, the vent 202 included in the gas blowing region X2 rotates while continuously blowing out the gas. Note that the opening 401b of the journal internal channel 401 that does not communicate with the second recess 811b is covered and closed by the inner peripheral surface of the slide body 81, and no gas is introduced.

  The slide body 81 is configured such that the numerical aperture of the journal internal flow path 401 communicating with the first recess 811a is changed according to the position in the axial direction with respect to the journal 4, and is communicated with the second recess 811b. The numerical aperture of the journal internal flow path 401 is configured to be constant. Specifically, as shown in FIG. 5, in the state in which the slide body 81 is deployed, the opening shape of the first recess 811a is substantially trapezoidal, and the opening shape of the second recess 811b is approximately parallelogram-shaped. Is.

For example, in FIG. 5, in order to set the gas suction region X1 to the maximum angle range θmax (see FIG. 6) in the circumferential direction, the slide body 81 is moved to the right along the axial direction. On the other hand, in order to set the gas suction region X1 to the minimum angle range θmin (see FIG. 7) in the circumferential direction, the slide body 81 is moved to the left along the axial direction. Even if the slide body 81 is moved in the axial direction, the second recess 811b has a substantially parallelogram shape, and the numerical aperture of the journal internal channel 401 communicating with the second recess 811b is constant. The angular range in the circumferential direction of the gas blowing region X2 is constant. Thus, by moving the slide body 81 in the axial direction, the gas suction region X1 can be changed between the maximum angle range θ ₁ max and the minimum angle range θ ₁ min. The maximum angle range θ ₁ max and the minimum angle range θ ₁ min can be changed as appropriate according to the width dimension of the first recess 811 in the circumferential direction.

Further, even if the gas suction region X1 is the maximum angle range θ ₁ max and the minimum angle range θ ₁ min or an angle range therebetween, the gas blowing region X2 is adjacent to or close to the rotational direction feed side of the gas suction region X1. It is formed.

  Here, “adjacently formed” means that the gas venting region X2 includes the nearest vent 202 adjacent to the vent 202 at the rotation direction feed side end portion that forms the gas suction region X1. Is formed adjacent to the vent 202 at the rotation direction feed side end portion that forms the gas suction region X1, but the vent 202 close to the vent 202 is included in the gas blowing region X2. Say.

  In the induction heating roller device 100 configured as described above, the workpiece W is adsorbed to the surface of the roller body 2 from the contact start portion (the end opposite to the rotation direction) in the gas suction region X1 of the roller body 2. The roller body 2 is moved along with the rotation of the roller body 2 and moved to a contact end portion (end portion in the rotation direction) in the gas suction region X1 and then separated from the surface of the roller body 2 in the gas blowing region X2.

  According to the induction heating roller device 100 according to the present embodiment configured as described above, the vent hole 202 is provided on the entire circumference of the roller body 2, and the workpiece W is sucked by sucking gas from the vent hole 202. Can be adsorbed to the roller body 2 and brought into close contact therewith. Thereby, it is not necessary to apply tension to the surface of the roller body 2 by applying tension to the object to be processed W, and it is possible to perform the predetermined heat treatment by reliably bringing the object W into close contact with the surface of the roller body 2. .

  Further, since the gas suction region X1 is changed in the circumferential direction by the region changing mechanism 8, it is possible to easily change the processing of the workpiece W such as changing the portion of the roller main body 2 that closely contacts the workpiece W. In addition to this, it is possible to easily cope with various pass lines in which the contact area between the workpiece W and the roller body 2 is different. Furthermore, the workpiece W adsorbed on the roller body 2 can be suitably separated in the gas blowing region X2 by blowing the gas from the vent 202 provided in the roller body 2. Moreover, since the gas suction area X1 and the gas blowing area X2 can be changed by the area changing mechanism 8, the gas blowing area X2 can be changed according to the changed gas suction area X1, and the workpiece W It is possible to easily cope with various pass lines in which the contact area between the roller body 2 and the roller body 2 is different.

  The present invention is not limited to the above embodiment.

  For example, as the opening shape in a state where the first recess 811a is expanded, as shown in FIG. 8A, in addition to the embodiment, the opening shape is gradually reduced from one to the other in the axial direction. Alternatively, as shown in FIG. 8B, it may be reduced in the axial direction from the center to one and the other. Further, as shown in FIG. 8C, it may have a substantially parallelogram shape, or as shown in FIG. 8D, it has a substantially trapezoidal shape in which the lower base extends along the circumferential direction. It may be a thing.

  Moreover, in the said embodiment, although the width dimension in the circumferential direction of the 2nd recessed part 811b was made constant, the gas blowing area | region X2 was made into the fixed angle range irrespective of the gas suction area | region X1, However, 2nd recessed part 811b The opening of the journal internal channel 401 communicating with the second recess 811b according to the position in the axial direction with respect to the journal 4 is made trapezoidal or the like in the same manner as the opening of the first recess 811a. The number may be changed so that the angle range of the gas blowing region X2 can be changed.

  Furthermore, although the slide body 81 of the said embodiment is being fixed to the journal 4 with respect to the circumferential direction, you may comprise it so that a slide in the circumferential direction is possible. If this is the case, by sliding the slide body 81 in the circumferential direction, as shown in FIG. 9, the gas suction region X1 and the gas blowing region X2 can be moved in the circumferential direction, for example, while maintaining their circumferential dimensions. .

  In addition, in the above embodiment, the gas is introduced into the journal internal flow path opened in the side peripheral surface of the journal. However, in the case where the gas flow passage opens in the side peripheral surface of the roller body, the slide body Can be changed on the side peripheral surface of the roller body.

  In addition to the configuration in which two gas flow paths are connected to one journal internal flow path, one gas flow path or three or more gas flow paths may be connected to one journal internal flow path. In addition, when one gas flow path is connected to one journal internal flow path, the gas suction region can be finely changed in the circumferential direction.

  Moreover, in the said embodiment, although the area | region change mechanism formed the gas blowing area | region X2 in the surface of a roller main body, it forms only the gas suction area | region X1 without forming the gas blowing area | region X2. There may be.

  In addition, the embodiment has described the induction heating roller device as the heating roller device, but in addition, a heating roller device in which a heating mechanism such as a heater is arranged in the hollow of the roller body, or a heat medium in the hollow of the roller body. The present invention can also be applied to a fluid flow roller device having a heat medium flow mechanism that heats or cools the roller body by flowing.
