Also have, in this form of implementation, the 1st peristome 22 constitutes according to the size that the cold-cathode fluorescence lamp 1 that makes on the periphery that is wound in core 41 passes.In addition; As stated; Be supported on the cold-cathode fluorescence lamp 1 of the straight tube-like on the location division 33 of supporting slice portion 31, and the distance between the bottom wall portion 21 of shell 18, promptly; Cold-cathode fluorescence lamp 1 batches in volume and batches the position on the core 41, and the distance between the bottom wall portion 21 of shell 18 is shorter than 1/2 the length (with reference to Fig. 5 (a) etc.) of the height of the cold-cathode fluorescence lamp 1 that is dual spiral-shaped shaping slightly.Thus, if Yi Bian through making 41 rotations of volume core, Yi Bian make its decline; Cold-cathode fluorescence lamp 1 is batched on the core 41; Then the stage before the batching of the length direction all zones of cold-cathode fluorescence lamp 1 (shaping) accomplished, batching on volume core 41 in the cold-cathode fluorescence lamp 1 is the position of dual spiral-shaped shaping; And the position that is wound with cold-cathode fluorescence lamp 1 in the volume core 41 exports to the outside (below) of shell 18 via the 1st peristome 22.In addition, in this form of implementation, that kind shown in Fig. 6 (a) constitutes in the following manner, and this mode is: before the integral body that is wound on the cold-cathode fluorescence lamp 1 on the core 41 exports to the outside of shell 18, volume core 41 is descended.
In addition, on volume core 41, not shown well heater is set, it heats the position that is wound with cold-cathode fluorescence lamp 1 in the main part 43 (formation of swivelling chute 45 is interval) as volume core heating arrangements.In this form of implementation, constitute in the following manner, this mode is: follow the lifting action of volume core 41, well heater is started the switching controls of closing.In addition, the volume core of this form of implementation 41 constitutes through the high metal (for example, copper etc.) of heat conductivity, still, also can constitute through other material (for example, the good pottery of release property etc.).
Also have; That kind shown in Fig. 6 etc.; Shaping appts 11 comprises the chuck 51 as maintaining body; Its below the 1st peristome 22, keep through be wound on be configured as on the core 41 dual spiral-shaped and export to the cold-cathode fluorescence lamp 1 of the outside (below) of shell 18 through the down maneuver of rolling up core 41.Chuck 51 is a following structures, and wherein, comprising can be relative according to along continuous straight runs, a pair of operation sheet 53 of mutual approaching mode displacement, and through operation sheet 53, the periphery of clamping cold-cathode fluorescence lamp 1 like this, keeps cold-cathode fluorescence lamp 1.In this form of implementation; Constitute in the following manner; This mode is: in the integral body of the cold-cathode fluorescence lamp that is dual spiral-shaped shaping 1 via the 1st peristome 22; Export to after the outside of shell 18,, keep the bottom of the derivation direction leading section side of relative the 1st peristome 22 in the cold-cathode fluorescence lamp 1 through chuck 51.Then, through a pair of operation sheet 53, clamping is the state of the cold-cathode fluorescence lamp 1 of dual spiral-shaped shaping; Opposite direction makes 41 rotations of volume core when batching cold-cathode fluorescence lamp 1 on the edge; Make its rising simultaneously, thus, volume core 41 takes off from dual spiral-shaped cold-cathode fluorescence lamp 1.
With reference to Fig. 2～Fig. 8, cold-cathode fluorescence lamp 1 is configured as dual spiral-shaped process describes below.
At first; That kind as shown in Figure 8; Be in the location division 33 of each supporting slice portion 31 of the non-supporting device 13 that holds state relatively; The cold-cathode fluorescence lamp 1 of straight tube-like is provided with in the following manner, and this mode is: the length direction pars intermedia of cold-cathode fluorescence lamp 1, and consistent with the length direction pars intermedia of shell 18.Then, that kind as shown in Figure 2 rises supporting slice portion 31, and supporting device 13 is in and holds state, cold-cathode fluorescence lamp 1 is contained in the internal space 19 of process furnace 12 of hot environment.At this moment, volume core 41 be positioned at the cold-cathode fluorescence lamp 1 that is supported in the supporting slice portion 31 above holding fix.In addition, the volume core 41 that is positioned at holding fix is in a pair of snap projection 44 edges and the perpendicular direction state arranged side by side of the length direction of shell 18.In addition, the both ends of cold-cathode fluorescence lamp 1 are positioned at the outside of shell 18 via open-ended 25.
Heat fully at cold-cathode fluorescence lamp 1 that (temperature that is in cold-cathode fluorescence lamp 1 is higher than annealing point to the internal space 19 that is positioned at shell 18; And be lower than the state of softening temperature) after; That kind as shown in Figure 3; Do not make 41 rotations of volume core, and make its cold-cathode fluorescence lamp 1 that drops to straight tube-like be held on the ready position between a pair of snap projection 44.
Then, that kind as shown in Figure 4 on one side through snap projection 44, is hooked cold-cathode fluorescence lamp 1, makes volume core 41 (see from the bottom surface, counterclockwise), make its decline simultaneously, like this, cold-cathode fluorescence lamp 1 is wound on the periphery of core 41 to right rotation on one side.In addition; Be wound in the position of interior all sides of the cold-cathode fluorescence lamp 1 on the core 41, embed in the swivelling chute 45 on the periphery that is formed at volume core 41, thus; Realization is wound in the location of the cold-cathode fluorescence lamp 1 on the core 41, and prevents coming off of cold-cathode fluorescence lamp 1 relative volume core 41.
In addition, follow carry out of cold-cathode fluorescence lamp 1 at the coiling of volume on the core 41, volume core 41 descends, and from the 1st peristome 22, protrudes in the outside of shell 18, is wound in the outside that cold-cathode fluorescence lamp 1 on the core 41 exports to shell 18 successively.That is, the position that the shaping from cold-cathode fluorescence lamp 1 finishes begins to cool down successively.
In addition; In the shaping that begins cold-cathode fluorescence lamp 1 originally; About the both ends of the cold-cathode fluorescence lamp 1 of the outside that is positioned at shell 18, follow carry out of batching of cold-cathode fluorescence lamp 1 on volume core 41, be pulled in the internal space 19 of shell 18; Batch the stage on volume core 41, be in heating condition fully.In addition, the well heater that is built in the volume core 41 cuts out when beginning to batch, and the cold-cathode fluorescence lamp 1 that is discharged to the outside of shell 18 does not heat through the well heater of volume core 41.
So that kind as shown in Figure 5 after the length direction integral body with cold-cathode fluorescence lamp 1 is wound in the release on the core 41, and before the integral body of cold-cathode fluorescence lamp 1 fully is discharged to the outside of shell 18, descends volume core 41.In addition, volume core 41 from accomplish cold-cathode fluorescence lamp 1 batch batch the completing place, drop to the derivation that cold-cathode fluorescence lamp 1 is exported to the outside of process furnace 12 finish the position during; Also can make this volume core 41 rotations; Accompanying rotation and make its decline quickly not also can derive when finishing the position being positioned at, through rotation carry out towards inching; Make its decline simultaneously, thus make cold-cathode fluorescence lamp 1 for desirable towards.In addition; Owing to form the position of the interior all sides in the dual spiral-shaped cold-cathode fluorescence lamp 1; Be in the state of the inboard of the swivelling chute 45 that embeds volume core 41; Even so leave under the situation of direction protrusion 28 at cold-cathode fluorescence lamp 1, cold-cathode fluorescence lamp 1 can not come off from volume core 41 (swivelling chute 45) yet.
That kind as shown in Figure 6 derives the position that finishes if cold-cathode fluorescence lamp 1 arrives, and then chuck 51 moves, so that through a pair of operation sheet 53, clamping is the cold-cathode fluorescence lamp 1 of dual spiral-shaped shaping.In this form of implementation, constitute in the following manner, this mode is: be in the cold-cathode fluorescence lamp 1 of dual spiral-shaped shaping, the carrying out of in advance deriving from shell 18 the refrigerative bottom, keep through chuck 51.So, if through chuck 51, keep cold-cathode fluorescence lamp 1, then roll up core 41 and rise opposite left-hand rotation (seeing CW from the bottom surface) rotation the time when batching on the edge.Thus, that kind as shown in Figure 7 from the cold-cathode fluorescence lamp that is dual spiral-shaped shaping 1 that keeps through chuck 51, is taken off volume core 41.As stated, dual spiral-shaped cold-cathode fluorescence lamp 1 is formed.
In addition, take off volume core 41 from cold-cathode fluorescence lamp 1 after, volume core 41 rises to holding fix, prepares the shaping of next cold-cathode fluorescence lamp 1.In addition, if volume core 41 is in fully the completing place of taking off of from dual spiral-shaped cold-cathode fluorescence lamp 1, taking off, then be built in the heater starting in the volume core 41.In addition, the volume core 41 from taking off the completing place, rise to holding fix during; Also can make this volume core 41 rotations; Accompanying rotation and rising not also can be when being in holding fix, according to the perpendicular direction mode arranged side by side of a pair of snap projection 44 edges and the length direction of shell 18; On one side through rotation carry out towards inching, Yi Bian rise.
As above specifically described; If adopt this form of implementation; When the shaping of cold-cathode fluorescence lamp 1, even under the situation in the stage before cold-cathode fluorescence lamp 1 whole shaping (batching) is accomplished, also with the position on the core 41 of batching in the cold-cathode fluorescence lamp 1; Via the 1st peristome 22, export to the outside of shell 18 successively.Thus, the position that the end from cold-cathode fluorescence lamp 1 is shaped begins to cool down successively.So and from the inside of process furnace 12, the shaping of cold-cathode fluorescence lamp 1 is accomplished, the refrigerative occasion of beginning cold-cathode fluorescence lamp 1 is compared, and can begin to cool down step quickly.Consequently, can seek the effects such as raising of production efficiency.In addition; The refrigerative occasion is carried out in the inside that is process furnace 12, or with the mode of die sinking to open process furnace 12 largely, take out the occasion of cold-cathode fluorescence lamp 1; Because the temperature of the internal space 19 of process furnace 12 is low; So for next cold-cathode fluorescence lamp 1 forms, internal space 19 is in before the hot environment once more, needs the more time.In this regard, in this form of implementation,, cold-cathode fluorescence lamp 1 is exported to the outside, cold-cathode fluorescence lamp 1 is carried out the refrigerative mode constitute, thus, can avoid above-mentioned rough sledding from process furnace 12 according to through via the 1st peristome 22.
In addition; Because through cold-cathode fluorescence lamp 1 being wound on the bending forming of the cold-cathode fluorescence lamp 1 that carries out on the periphery of core 41; Be to carry out, so can under certain temperature environment, carry out the shaping of cold-cathode fluorescence lamp 1 from first to the end in the internal space 19 of process furnace 12.So, for example, can avoid carrying out the occasion of the shaping of cold-cathode fluorescence lamp 1 in the outside of process furnace 12, owing to be shaped midway, the temperature of cold-cathode fluorescence lamp 1 has bigger variation, the situation that is difficult to be shaped.In addition, owing to carry out the shaping of cold-cathode fluorescence lamp 1, so even still can compatibly not be shaped under the situation of heats cold cathode fluorescent lamp 1 exceedingly having in the inside of process furnace 12.So, can avoid cold-cathode fluorescence lamp 1 too softening, the situation that cold-cathode fluorescence lamp 1 is distorted, the shortening that can seek to cool off required time, effects such as the saving of energy.
In addition, be used for the cold-cathode fluorescence lamp that is dual spiral-shaped shaping 1 is exported to the 1st peristome 22 of the outside of shell 18, be formed on the bottom wall portion 21 of shell 18.Thus, be formed at the top wall portion 26 of shell 18 with for example the 1st peristome 22 or the occasion on the side wall portion is compared, can make the heat of the internal space 19 of process furnace 12 be difficult to be discharged to the outside.So, can suppress to form the 1st peristome 22 and the calorific loss of the internal space 19 of causing, can seek the effect of the saving etc. of energy.In addition, be difficult to be discharged to the outside from the 1st peristome 22 through the heat that makes process furnace 12, clamping the 1st peristome 22 can increase the temperature head between process furnace 12 inside and outside.That is,, can suppress because of being discharged to outside heat from the 1st peristome 22, and make cold-cathode fluorescence lamp 1 be difficult to the refrigerative situation although cold-cathode fluorescence lamp 1 is exported to the outside from the 1st peristome 22.So, can just export to after the outside from the 1st peristome 22, suitably carry out the cooling of cold-cathode fluorescence lamp 1.In addition, be arranged at the top wall portion 26 of shell 18 with the 1st peristome 22 or the occasion on the side wall portion is compared, in the time of can being reduced at the batching of cold-cathode fluorescence lamp 1, the shape of the location division 33 that cold-cathode fluorescence lamp 1 supports with the mode that does not misplace.
In addition, chuck 51 is a following structures, wherein, keeps through in the cold-cathode fluorescence lamp 1 that is dual spiral-shaped shaping, exports to outside mode in advance and carries out bottom the refrigerative from process furnace 12.So, can not cause the situation of the distortion etc. of cold-cathode fluorescence lamp 1, can keep cold-cathode fluorescence lamp 1 securely, that can more successfully roll up core 41 relative cold-cathode fluorescence lamps 1 takes off operation etc.
In addition, on the top wall portion 26 of shell 18, near the outstanding downwards direction protrusion 28 of setting volume core 41; Volume core 41 rotation on one side; Descend on one side, thus, cold-cathode fluorescence lamp 1 is pulled between volume core 41 and the direction protrusion 28; And, it when carrying out bending machining, it is wound on the periphery of core 41 in that being crimped on direction protrusion 28.Through this scheme; Cold-cathode fluorescence lamp 1 is being wound on 41 last times of core; Even at the length direction both ends that keep cold-cathode fluorescence lamp 1; Under the not in tension situation of cold-cathode fluorescence lamp 1 (even be free-ended situation under at the both ends of cold-cathode fluorescence lamp 1), still can exactly cold-cathode fluorescence lamp 1 be wound on the core 41.So, be wound in 41 last times of core at cold-cathode fluorescence lamp 1, compare with the such scheme in length direction both ends that keeps cold-cathode fluorescence lamp 1, still can seek the simplification of structure (supporting slice portion 31 etc.), the effect of the raising of manufacturing operation property etc.Particularly; As this form of implementation, in the shaping of beginning cold-cathode fluorescence lamp 1 originally, the fly out outside of shell 18, the both ends of cold-cathode fluorescence lamp 1; The both ends that keep cold-cathode fluorescence lamp 1; The Stress this point of keeping fluorescent tube is very difficult, and in this occasion, this action effect is further remarkable.
Also have, supporting device 13 constitutes in the following manner, and this mode is: its state can be in the location division 33 be arranged in process furnace 12 internal space 19 hold state, and location division 33 changed in non-the holding between the state of the outside of process furnace 12.Thus, be in the non-location division 33 that holds the supporting device 13 of state relatively, Yi Bian make the position alignment of (before being shaped) cold-cathode fluorescence lamp 1 of straight tube-like; Load on one side, then, the state of supporting device 13 is changed to hold state; Like this, can cold-cathode fluorescence lamp 1 be contained in the process furnace 12.So, the effect of the operation property raising in the time of can seeking to be contained in cold-cathode fluorescence lamp 1 in the process furnace 12 etc.
In addition, owing to be than softish, so through batching in the position of rolling up on the core 41 in the cold-cathode fluorescence lamp 1, the position that a cantilever support is not batched as yet has the danger of hanging down because of deadweight in the position of not batching through the cold-cathode fluorescence lamp 1 of process furnace 12 heating.Relative this situation, according to this form of implementation, the position of not batching as yet in the cold-cathode fluorescence lamp 1, a cantilever support thus, is provided with supporting slice portion 31 according to the mode that can support the position of not batching the length that does not hang down on the position of having batched.Thus, even under the situation of the supporting that does not have location division 33, still can cold-cathode fluorescence lamp 1 compatibly be configured as dual spiral-shaped until at last.
Also have, in volume core 41, be built-in with the well heater that itself is heated.Thus, can make with the cold-cathode fluorescence lamp that has batched 1 to export to the outside of process furnace 12 and receive the temperature that refrigerative is rolled up core 41, rise to the temperature of the shaping that is suitable for cold-cathode fluorescence lamp 1 through well heater quickly.So, can shorten to time of shaping of next cold-cathode fluorescence lamp 1 of beginning, consequently, can seek effects such as productive raising.
