  Hereinafter, an example of an embodiment of the present invention will be described in detail based on the drawings.

  FIG. 1 is a configuration diagram schematically showing a main part of a heat exchange control device of a production line for a strip according to an example of an embodiment of the present invention, and FIG. 2 is a schematic operation explanatory diagram thereof. Since it is a schematic diagram for explanation, it is not necessarily an accurate cross section of each member.

  In this embodiment, the present invention is applied to the heat exchange control device 15 of the production line 14 for the strip-like body (for example, a laminate film) 12.

  The belt-like body 12 is manufactured by being conveyed while being in rolling contact with a plurality of rolls (only one is shown in FIG. 1). In this example, among the plurality of rolls, the illustrated roll 16 is constituted by a heating roll (heat exchange roll) that applies heat to the strip 12. That is, the heating roll 16 has a built-in heater (not shown), and the temperature of the outer peripheral surface 16 a of the heating roll 16 is the temperature at which the strip 12 is wound around the outer peripheral surface 16 a of the heating roll 16. Rather, it is configured to be maintained at a higher predetermined temperature.

  The configuration itself for maintaining the outer peripheral surface 16a of the heating roll 16 at a predetermined temperature is not particularly limited. In short, the temperature of the outer peripheral surface 16a is maintained higher than the temperature at which the strip 12 is caught so that heat moves from the heating roll 16 side to the strip 12 as a result (so that heat can be exchanged). Just do it. In this embodiment, a heating roll having the same configuration as the conventional one is used as it is.

  In the production line 14 of the belt-like body 12 according to this embodiment, the angle θ that contacts the heating roll 16 when the belt-like body 12 moves, that is, the distance Lp at which the belt-like body 12 is brought into rolling contact with the heating roll 16 is changed. A possible path changing mechanism Pc1 is provided.

  In this embodiment, the path changing mechanism Pc1 moves the sub-rolls 36 to 39 that can change the path of the belt-like body 12 with respect to the heating roll 16 by contacting the control unit 19 and the belt-like body 12. A sub-roll moving unit 20 to be operated.

  The controller 19 controls the overall movement of the path changing mechanism Pc1, and outputs a drive signal for a motor 22 to be described later. The control unit 19 includes a memory 19A in which various data are stored in advance for each type of the belt-like body 12, and an arithmetic circuit 19B. Further, various signals, for example, the temperature signal S1 of the strip 12 and the heating roll 16 detected in real time, the specific detection signal S2 related to the quality of the product, and the trouble occurrence signal M1 input manually, etc. The interface 19C and the like for taking in are provided. In this embodiment, the trouble occurrence signal M1 can be manually input by an operator, but instead of or in addition to this, for example, the temperature signal S1, the specific detection signal S2, etc. You may comprise so that it may produce | generate automatically within the control part 19 from information.

  The sub-rolls 36 to 39 are selectively brought into rolling contact with the belt-like body 12 by moving the rotation axes O1 to O4, and change the transport locus of the belt-like body 12 according to the rolling manner.

  The sub-roll moving unit 20 is connected to a common motor 22, input and output speed reducers 32 and 33 that are simultaneously driven by the motor 22, and the speed reducers 32 and 33. (A direction perpendicular to the paper surface of FIG. 1) The basic structure provided on the outside is composed of a total of four individual moving units 20A to 20D (one side in the axial direction: individual moving unit 20A on the front side of FIG. 1; Only 20B is shown).

  The individual moving unit 20A on the entry side (lower side of the paper in FIG. 1) and the individual movement unit 20B on the outgoing side (upper side of the paper in FIG. 1) are only symmetrical with respect to the horizontal plane H1, and the basic structure is as follows. Are the same. The individual moving parts 20C and 20D on the other axial side which are not shown in the figure are the same as the individual moving parts 20A and 20B which are shown in the figure but are symmetrical with respect to a plane perpendicular to the axis. . However, these individual moving units 20A to 20D do not necessarily have the same basic structure. The motor 22 may also be provided individually. When the motor 22 is common, the facilities can be shared, which is advantageous in terms of cost and simplifies the control.

  The individual moving units 20A and 20B on the entry side and the exit side include a common guide unit 25 that constrains the movement trajectory of the rotation axes O1 to O4 of the sub-rolls 36 to 39 concentrically with the rotation axis O6 of the heating roll 16. .

  For convenience, the description will be made more specifically by mainly focusing on the individual moving part 20A on the entry side. The individual movement part 20A on the entry side includes a screw 44 that receives the output of the speed reducer 32, and a screw that rotates as the screw 44 rotates. 44, a support plate 48 that is swingably connected to the nut 46 (or a member integral with the nut 46) and supports the sub rolls 36 and 37 on the entry side, and the support plate 48 provided with the above-mentioned The slide unit 50 mainly engages with the guide unit 25 and slides along the guide unit 25 to move the support plate 48. The screw 44 and the nut 46 constitute a so-called ball screw set 45. The screw 44 is connected to the output shaft 32A of the speed reducer 32 via a universal joint portion 32B so as to be swingable.

  The sub-rolls 36 to 39 are supported by the support plate 48 in such a manner that the pair of support plates 48 of the sub-roll moving unit 20 located on both outer sides in the rotation axis direction of the heating roll 16 are connected. The support plate 48 is movable along the guide unit 25 via the slide portion 50 while being allowed to swing around the nut 46 portion. As is clear from FIG. 2, the sub-rolls 36 to 39 do not come into contact with the heating roll 16 in any moving position.

  In this embodiment, at the time of the maximum heat exchange, the strip 12 does not roll-contact with the inlet side sub-rolls 36 and 37 or the outlet side sub-rolls 38 and 39. When changing and controlling the amount of heat exchange, the belt-shaped body 12 rolls in contact with the inlet side sub-rolls 36 and 37, rolls in contact with the heating roll 16, and also rolls in contact with the outlet side sub-rolls 38 and 39. When the conveyance of the belt-like body 12 is stopped or when trouble occurs, the belt-like body 12 rolls into contact with only the inlet side sub-rolls 36 and 37 and the outlet side sub-rolls 38 and 39 and is separated from the heating roll 16.

  As described above, the sub-roll moving unit 20 of the path changing mechanism Pc1 is located outside the rotation axis direction of the heating roll 16. That is, all of the guide unit 25, the support plate 48, and the ball screw set 45 are located outside the heating roll 16 in the rotation axis direction. Further, the sub-rolls 36 to 39 are not in contact with the heating roll 16 in any moving position. On the other hand, the guide unit 25 is not formed over the entire circumference of the heating roll 16, but has an opening 25A in a part thereof. The opening 25A has a size L1 through which both end portions of the heating roll 16 (portions supported by bearings not shown) can pass. Accordingly, the heating roll 16 can be replaced through the opening 25A while the path changing mechanism Pc1 is incorporated in the production line.

  Next, mainly referring to FIGS. 2A to 2C, the operation of the heat exchange control device 15 of the production line 14 of the strip 12 will be described.

  Conventionally, for example, in order to flexibly cope with a change in temperature control required in association with a change in the type or shape of a belt-like body, specifically, for example, switching to a heat exchange roll having a different diameter. Alternatively, a plurality of heat exchange rolls are prepared, and the use or non-use of each heat exchange roll is differentiated by switching the main path of the belt to change the number of use. For this reason, the time loss for switching the path and the loss of the product from line stop to start-up are large, and above all, it is extremely difficult to quickly perform the optimal and fine-tuned temperature control of the strip. Met.

  In the present embodiment, detailed temperature control can be quickly performed easily and flexibly without performing such work. This will be specifically described below.

  Focusing on the entry side, in this production line 14, when it is desired to sufficiently heat the strip 12 by the heating roll 16, the motor 22 is operated by a drive signal from the control unit 19, as shown in FIG. As described above, the screw 44 is rotated by the output of the speed reducer 32 driven by the motor 22, and the nut 46 is moved to the tip end side (counter speed reducer side) of the screw 44.

  As a result, the support plate 48 swingably connected to the nut 46 (or a member integral with the nut 46) moves to the vicinity of the opening 25A of the guide unit 25, and the sub-rolls 36 and 37 are moved to the sub-rolls 36 and 37. It falls within the range inside the main path when there is no. That is, at this time, the strip 12 does not contact the sub-rolls 36 and 37.

  Since the same movement is performed on the exit side, the strip 12 can secure a contact angle of θ1 = 180 degrees with respect to the heating roll 16, and the rolling contact distance for a half circumference of the heating roll 16. Lp1 sufficiently contacts the heating roll.

  On the other hand, in order to further reduce the amount of heat received from the heating roll 16, as shown in FIG. 2B, the screw 44 is rotated, and the nut 46 is moved to the speed reducer 32 side. The nut 46 moves linearly on the screw 44, and the nut 46 moves along the guide unit 25 via the support plate 48 and the slide portion 50. Therefore, the nut 46 draws an arc coaxial with the heating roll 16 together with the support plate 48 and approaches the speed reducer 32 side. The screw 44 swings with the universal joint portion 32B of the speed reducer 32 as a fulcrum so as to follow the movement of the nut 46.

  As a result, the sub-rolls 36 and 37 supported by the support plate 48 slide together (with the support plate 48), move coaxially with the heating roll 16 and without contact with the heating roll 16. Since this action is performed in the same way on the exit side, the main path of the strip 12 is changed so that it is symmetrically expanded on both the entrance and exit sides, and the contact angle θ of the strip with respect to the heating roll 16 is It decreases from θ1 (180 degrees) to θ2. That is, the rolling contact distance Lp decreases from Lp1 (half circumference of the heating roll 16) to Lp2.

  In this embodiment, since the motor 22 is common on the entry side and the exit side, the movement on the entry side and the exit side are performed in synchronization, and as a result, the temperature of the strip 12 can be changed quickly. When motors are provided separately on the input side and the output side, in addition to the control mode in which the input side and the output side are moved synchronously with an emphasis on the change speed, fine adjustment is emphasized and the input and output sides are emphasized. A control mode for individually moving the sides can also be realized.

  In order to further reduce the amount of heat received from the heating roll 16, the nut 46 is further moved to the speed reducer 32 side by further rotating the screw 44 as shown in FIG. As a result, the contact angle θ between the heating roll 16 and the strip 12 is further reduced from θ2, and eventually the strip 12 is completely separated from the heating roll 16 (both the contact angle θ and the rolling contact distance Lp are zero). In other words, the amount of heat received from the heating roll 16 when the band-like body 12 passes through the portion of the heating roll 16 can be made zero by transporting the band-like body 12 without contacting the heating roll 16.

  The amount of heat that the belt 12 receives from the heating roll 16 is substantially proportional to the contact angle θ (rolling distance Lp). In this embodiment, the maximum amount of heat received in the state of FIG. The desired amount of received heat up to the minimum amount of received heat (zero) in the state of) can be easily obtained by driving the motor 22 according to a command from the control unit 19 and determining the position of the nut 46 by rotating the screw 44. And it can be set quickly.

  Since the heat exchange control device 15 according to this embodiment has such an effect, for example, contact is made by feedforward control based on data stored in advance in the memory 19A of the control unit 19 for each material to be manufactured. It is possible to realize control in which the angle θ is changed and set in advance to perform heat exchange. Further, for example, based on a temperature signal S1 of a material detected in real time or a heating roll, or a specific detection signal S2 related to product quality, the contact angle θ is changed and set in real time by feedback control. It is also possible to realize control for performing exchange. Further, as described later, when the trouble occurrence signal M1 is manually input to the control unit 19, or the trouble signal is automatically generated in the control unit 19 from information such as the temperature signal S1 or the specific detection signal S2. Control is performed so that the belt 12 is separated from the heating roll and the contact angle θ is zero (the rolling contact distance Lp is zero) so that heat exchange with the heating roll 16 is not performed. it can.

  In this embodiment, the heating roll has been described as an example of the heat exchange roll. However, in the present invention, the same effect can be obtained when a cooling roll is used as the heat exchange roll.

  In this embodiment, as the path changing mechanism Pc1, the sub-rolls 36 to 39 that can change the main path of the belt-like body 12 with respect to the heating roll 16 when the control unit 19 and the belt-like body 12 come into contact with each other, And a sub-roll moving unit 20 that moves the 39 rotation axes O1 to O4. Therefore, the above-described operation can be obtained only by providing the path changing mechanism Pc1 (at a low cost) without changing the basic configuration of the production line 14 at all.

  In this embodiment, the sub-roll moving unit 20 that moves the rotation axes O1 to O4 of the sub-rolls 36 to 39 has the rotation axes O1 to O4 of the sub-rolls 36 to 39 coaxially with the heating roll 16 (concentrically). ) I try to move it. For this reason, the difference in path length between when the strip 12 is in contact with the heating roll 16 and when it is not in contact with the heating roll 16 can be minimized. This effect is very large in reality in that a mechanism for coping with a change in tension accompanying a change in path length can be simplified and a large-scale accumulator facility (tension adjustment facility) is not required.

  Moreover, in this embodiment, the structure provided with the guide unit 25 which constrains the movement locus | trajectory of rotation axis O1-O4 of this sub-roll 36-39 on the concentric circle with the heating roll 16 as a specific structure of the sub-roll moving part 20. Is adopted. For this reason, the control system is simple, and the main path can be changed by the sub-rolls 36 to 39 reliably at low cost.

  In this embodiment, a plurality of sub-rolls 36, 37, or 38, 39 are provided for each of the entrance side and exit side of one heating roll 16 (two each). First, since the sub-rolls 36 to 39 are provided on both the entry side and the exit side, the contact angle adjustment range can be expanded. Further, since there are a plurality of sub-rolls 36, 37, or 38, 39 on the same side, the path can be changed step by step, and the path can be changed very smoothly. Further, a path closer to the concentric circle can be formed with respect to the heating roll 16, and the difference in path length can be further reduced.

  Moreover, in this embodiment, since the strip | belt-shaped body 12 is passed so that it may contact the same side of several sub-rolls 36, 37, or 38,39, one surface of a strip | belt-shaped body does not contact any roll. The state can be maintained. For this reason, it is effective when a predetermined condition is imposed on the surface characteristics of the one surface and it is not desired to contact any of the rolls.

  In the case where a plurality of sub-rolls 36, 37, or 38, 39 are continuously arranged on the same side of the entry side or the exit side as in this embodiment, for example, FIG. ), The belt-like body 12 may be passed between the two sub-rolls 36 and 37 and between the sub-rolls 38 and 39. Thereby, not only the contact angle θ of 180 degrees or less (the rolling contact distance Lp less than half a circle) but also the contact angle θ exceeding 180 degrees (the rolling contact distance Lp more than a half circle) is freely and continuously formed. You will be able to

  In this embodiment, the path changing mechanism is configured to completely separate the belt-like body 12 from the heating roll 16 as shown in FIG. For this reason, when some trouble occurs on the production line 14, the strip 12 can be immediately separated from the heating roll 16. Since the effect of complete separation brings about a very large merit in practical use, it is supplemented here a little.

  1stly, the ease of setting of the heat exchange roll to be used can be improved significantly. That is, according to the present embodiment, for example, by arranging a plurality of heating rolls with sub-rolls 36 to 39 as shown in FIG. 3, any of the heating rolls 36 to 39 are selectively separated completely. It is possible to select whether or not to use the heating roll 16 even during operation. Moreover, when there are a plurality of types of heating rolls with different surface finishes, the heating rolls to be used according to the type of the product can be selected by simply selectively separating the heating rolls 36 to 39 that are not desired to pass through (( It is also possible to make a selection (in consideration of quality).

  Second, emergency evacuation is possible when trouble occurs. Since the belt-like body 12 that is the manufacturing object is conveyed at a high speed, it contacts the heating roll 16 only for a short time. For this reason, in general, the heating roll 16 is often set to a “high temperature” accordingly. Therefore, when the line stops due to some trouble, if the strip 12 remains in contact with the heating roll 16 for a long time, the strip 12 is melted and a great deal of “cleanup” is required. End up. For this reason, conventionally, when such a trouble occurs, it has been necessary to quickly separate the strip from the heating roll even if the strip is intentionally cut. As a result, many strips were wasted, and a great deal of time and effort was required for re-startup. According to the present embodiment, when trouble or the like occurs, the strip 12 can be immediately separated from the heating roll 16. Therefore, for example, as shown in FIG. 3, by applying the configuration as described above to all the heat exchange rolls 16, the entire belt-like body 12 is completely separated from all the heating rolls 16 along with the occurrence of trouble. be able to. Therefore, it is possible to minimize the strip 12 that is wasted, and it is easy to start up again.

  Various variations are possible in the present invention.

  For example, the mode of changing the path of the strip using the sub-roll is not limited to the above example. For example, as shown in FIG. 4, the rotation axes O7 and O8 of the sub-rolls 70 and 71 may be moved “linearly”. Moreover, the sub-rolls 70 and 71 may be provided one by one on the entry side and the exit side, for example. Even with such a configuration, the contact angle θ between the heat exchange roll 76 and the strip 78 can be changed, for example, between θ5 and zero, and the rolling distance Lp can be changed between Lp5 and zero. The effect similar to the previous embodiment can be obtained at a lower cost. Further, although not shown, the sub-roll 70 or 71 may be disposed only on either the entry side or the exit side, and the arrangement of the other sub-roll 71 or 70 may be omitted.

  In the present invention, the specific configuration of the sub-roll moving unit that moves the rotation axis of the sub-roll is not limited to the above example.

  For example, as shown in FIG. 5, rod-like arms (or disc-like plates) 82 and 83 that are rotatable concentrically with the axis O <b> 9 of the heat exchange roll 80 are prepared. In addition, the sub-rolls 84 and 85 are rotatably arranged on the rod-like arms 82 and 83 at a radial position slightly outside the outer periphery 80a of the heat exchange roll 80. In this case, two or more sub-rolls may be arranged on one arm. Then, the arms 82 and 83 in which the sub-rolls 84 and 85 are rotatably arranged are rotated around the axis of the heat exchange roll 80 as shown in FIGS. Even with such a configuration, it is possible to obtain the same effect as that of the embodiment described with reference to FIGS.

  Furthermore, in the present invention, the configuration of the path changing mechanism is not necessarily limited to the configuration using sub-rolls. For example, as shown in FIGS. 6A and 6B, the axial center O15 of the heat exchange roll 88 itself may be moved. Also with such a configuration, the contact angle θ (that is, the rolling contact distance Lp) between the heat exchange roll 88 and the belt-like body 89 is similarly changed from, for example, θ7 to θ8 (Lp7 to Lp8) in the example of FIG. be able to. In this case, a heat exchange roll moving unit (not shown) that moves the heat exchange roll 88 constitutes the path changing mechanism of the present invention.

  Further, in the present invention, as already described, the present invention can be effectively applied even when a plurality of heat exchange rolls exist. As the heat exchange roll in this case, for example, when a combination in which the set temperatures of at least two continuous heat exchange rolls are different from each other is adopted, the contact angle (contact distance) can be changed. The flexibility can be greatly increased. In this case, a heating roll and a cooling roll may be mixed.

  In addition, as can be understood from the example of the above embodiment, the rolling contact distance between the heat exchange roll and the strip is, for example, a) by the path changing mechanism of the entrance side angle or the exit side angle of the strip with respect to the specific heat exchange roll. Change either one (or both); b) Prepare multiple heat exchange rollers with different diameters, remove the heat exchange roll with an inappropriate diameter from the pass line by the path change mechanism, and exchange heat with the desired diameter Use a roll; c) Prepare a plurality of heat exchange rollers, and change the number of heat exchange rolls that are actually in rolling contact by a path changing mechanism; Of course, the above methods a) to c) may be appropriately combined.
