Summary of the invention
But the drying oven for coating according to above-mentioned document record in whole drying process, that is to say that spreading all over stove has used chain-linked conveyer endlong.Therefore, the engaging piece of seam, chain and the sprocket wheel of the company of chain joint part grades, and just having produced weares and teares considers to be worth doing.The wearing and tearing bits are in case attached on the vehicle body in the drying, just have the bad anxiety of application takes place on vehicle body.Therefore, just have the necessary cleaning work that the wearing and tearing bits are excluded in the stove of being used for continually.Because the complexity of the shape of the conveyer installed surface in the stove also plays negative effect, all these cleaning works are just very miscellaneous.In addition, dispose conveyer in stove, therewith correspondingly, the loss that is used for the heat of dry workpiece can increase corresponding degree.
At this point, in patent documentation 3, introduced the drying oven for coating that carries out the conveying of the vehicle body in stove without conveyer with supporting plate.But the supporting plate of document record is to drive by spreading all over the conveyer that stove is configured on the furnace hearth wall endlong.That is, owing to supporting plate is maintained on the holding member of being located on the conveyer, so supporting plate and conveyer move in stove simultaneously.Therefore, with described patent documentation 1,2 drying oven for coating of being put down in writing similarly, the anxiety that produces the wearing and tearing bits is also arranged in the drying oven for coating that patent documentation 3 is put down in writing.In addition, because the holding member of conveyer is outstanding in stove from siege, cleaning work is just more miscellaneous.And then because holding member spreads all over stove endlong with the predetermined distance configuration, so heat loss is also just bigger.
Conveying method in furnace of the present invention and drying oven are finished in view of described problem.Therefore, the object of the present invention is to provide a kind of need not make conveyer in the cocycle of stove total length, be difficult for to produce wearing and tearing bits, cleaning work is easy, heat loss is little conveying method in furnace and drying oven.
(1) in order to solve described problem, conveying method in furnace of the present invention, it is the conveying method in furnace that carries the supporting plate of workpiece, it is characterized in that, move by making with drive unit along any one this supporting plate in a plurality of these supporting plates of carrying (transmission) direction to link to each other, thereby continuous a plurality of these supporting plates are advanced in turn with each long distance (spacing) of this supporting plate that moves, this supporting plate that is arranged in the downstream in the stove is exported from outlet of still portion.That is, conveying method in furnace of the present invention is by any one supporting plate in continuous a plurality of supporting plates is moved, and makes the method for other supporting plate interlock.By the direct driving of drive unit is a supporting plate.The supporting plate that other supporting plate drives by driven device for example is driven indirectly.Drive unit can make supporting plate only move the long distance (spacing) of a supporting plate.Therefore, a plurality of supporting plates of Xiang Lianing are transferred with each long cinefilm that is like that of a supporting plate that moves with showing away web-like.
According to conveying method in furnace of the present invention, can make continuous a plurality of supporting plate interlocks via a supporting plate.That is just supporting plate that necessity of driving, is arranged.Therefore, need not make conveyer in the cocycle of stove total length.Thereby, be not easy to produce the wearing and tearing bits.
In addition, even if hypothesis is configured in drive unit in the stove, also as long as the length of a supporting plate of configuration.Therefore, the leveling of siege is easy.Thereby cleaning work is easy.In addition, even hypothesis is configured in drive unit in the stove, owing to as long as the length of a supporting plate is just enough, therefore compare with the situation of configuration conveyer on the stove total length, heat loss is little.And then, because the path that need not as in the past, on the stove total length, guarantee conveyer, so the free degree height of the configuration of the blow-off outlet of the interior hot fluid of stove, suction inlet.Again and then, the possibility that the mobile quilt of hot fluid hinders in stove is little.Moreover preferably preferably drive unit is configured in outside the stove.So, the dust that produces of the drive unit possibility of sneaking in the stove is little.In addition, the leveling of siege is easy.In addition, heat loss becomes littler.Moreover " in the stove " in this specification means in the hothouse of drying oven.
(2) preferably its formation is preferably, described drive unit moves the described supporting plate that is imported in the described stove from the stove inlet portion, by this supporting plate, a plurality of these supporting plates that link to each other are pushed in turn with each long distance (spacing) of this supporting plate that moves, with this supporting plate of being arranged in the downstream in this stove from the release of described outlet of still portion.
This formation is by from the stove inlet portion supporting plate being pushed, and that the supporting plate that will be arranged in the stove downstream is released stove is outer.According to this formation,, just can make the driving force of drive unit pass to each supporting plate as long as contact each other at the stove inner shoe.Therefore, the structure of supporting plate is very simple.
(3) preferably its formation to be preferably described drive unit be conveyer.According to this formation, configuration driven device more cheaply.In addition, because therefore conveyer can dispose the high drive unit of reliability all the time as the use real result height of conveying device in the stove.
(4) preferably its formation is preferably at the two ends of the throughput direction of described supporting plate, disposes upstream side handling part and the handling part, downstream that can load and unload mutually; In the time of in this supporting plate is imported into described stove, this handling part, downstream of this supporting plate engages with this upstream side handling part of this supporting plate that is arranged in the upstream in this stove; When this supporting plate in the downstream in being arranged in this stove was output outside this stove, separated with this handling part, downstream of this supporting plate of the upstream side that is configured in this supporting plate side by side this upstream side handling part of this supporting plate.
This formation is by upstream side handling part and handling part, downstream the supporting plate that links to each other can be linked together with loading and unloading mutually.According to this formation, can make that a plurality of supporting plates are mutual to be connected very close to each otherly.Therefore, can make the driving force that comes from drive unit rapider and loss ground between the supporting plate that links to each other, transmit.
(5) be preferably in the formation of described (4), preferably described drive unit moves this supporting plate that is arranged in the downstream in the described stove among a plurality of these supporting plates, by this supporting plate, a plurality of these supporting plates of linking are led in turn and send with each long distance (spacing) of this supporting plate that moves.
This formation is by drive unit the supporting plate in downstream to be moved, the formation of the supporting plate that links to each other by this supporting plate traction upstream side.According to this formation, the supporting plate in downstream can directly be driven by drive unit in the stove.Therefore, the supporting plate in downstream can be outputed to outside the stove reliably.

Secondly, describe making the action of going into the side lowering or hoisting gear under the support frame rising situation.When first sprocket wheel 201 rotated by the driving force that comes from motor M, chain 207a, 207b were rolled by the direction that descends to counterweight 206.Therefore, framework hold assembly 209a, 209b are pulled.Therefore, support frame 208, the supporting track 210 that is fixed on framework hold assembly 209a, the 209b also rises in going into side room 2.In addition, under the situation that support frame 208 is descended, as long as make motor M counter-rotating.
Action when secondly, the workpiece of the drying oven of this example being carried describes.From Figure 10 (a) to (f), represented the schematic diagram when workpiece is carried.At first, shown in (a), vehicle body W5 is carried on the supporting plate P5 that is configured on the side lowering or hoisting gear 20 by input unit 4.Then, shown in (b), the side lowering or hoisting gear 20 of going into that is carrying vehicle body W5 rises.At this moment, going out side lowering or hoisting gear 30 also rises.In addition, Kong input unit 4 reaches the vehicle body of supplying with usefulness next time to last procedure.The hook 16 of conveyer (earlier figures 4) is hooked on the supporting plate P5 that finishes after rising.Supporting plate 5 is drawn by hook 16, shown in (c), is pushed in the stove.At this, the length of slit (earlier figures 4) 107 is set to the length of a supporting plate and equates substantially.Therefore, supporting plate P5 is pushed in the stove with the such length of supporting plate.Supporting plate P4, P3, P2, P1 are forming a line on moving track 106 with the state that contacts with each other.Therefore, shown in (d), outside supporting plate P1 is pushed and comes out of the stove.Being pushed out into the outer supporting plate P1 of stove is carried on the side lowering or hoisting gear 30.Then, going out side lowering or hoisting gear 30 descends.In addition, going into side lowering or hoisting gear 20 also descends.Then, output device 5 moves to the down position that goes out side lowering or hoisting gear 30.Then, shown in (e), going out on the side lowering or hoisting gear 30, vehicle body W1 separates by output device 5 with supporting plate P1.That is, output device 5 was only accepted vehicle body W1 from going out side lowering or hoisting gear 30.Afterwards, shown in (f), output device 5 transfers vehicle body W1 to back one operation.In addition, empty supporting plate P1 is driven by driving wheel 111 (earlier figures 7) on double action track 110, moves to into side lowering or hoisting gear 20.Then, receive vehicle body W6 once more from input unit 4 going on the side lowering or hoisting gear 20.That is, turn back to the state of aforementioned (a).
Secondly, the drying oven of this example and the action effect of conveying method in furnace are described.According to this example, shown in Figure 10 as described above, can make continuous a plurality of supporting plate P4, P3, P2, P1 interlock via a supporting plate P5.That is, have driving necessity have only a supporting plate P5.Therefore, need not make conveyer in the cocycle of stove total length.Thereby, be not easy to produce the wearing and tearing bits.
In addition, in this example, dispose conveyer at the stove inlet portion.But shown in Figure 4 as described above, concavo-convex above the diapire 104 that produces owing to the setting of conveyer has only the slit 107 of hook 16, a pallet length.In addition, minimum toward the overhang of moving track 106.Therefore, almost being plane earth above the diapire 104 is configured.Therefore, cleaning work is easy to.In addition, compare with configuration conveyer on the stove total length, heat loss diminishes.And then owing to need not spread all over the path that stove is guaranteed conveyer endlong as in the past, so the free degree of the configuration of the interior blow-off outlet 105 of stove, suction inlet 103 is very high.
In addition, shown in Figure 10 as described above in this example, as long as supporting plate P4, P3, P2, P1 contact, the driving force of conveyer just can be delivered to each supporting plate in stove.Therefore, the structure of each supporting plate just can be realized simply.
In addition, in this example, use conveyer commonly used to be used as drive unit.Therefore, the manufacturing cost of drying oven just can reduce, and is in addition, very high for the reliability of fault etc.
In addition, according to this example, dispose going into side lowering or hoisting gear 20, going out side lowering or hoisting gear 30 of lifting substantially vertically.Therefore, compare with the sloping situation of configuration, the required space of lifting just can diminish.In addition, because the ratio of the transport path in stove input path and outgoing route height, heat is not easy to become separated in flight to the outside in stove.
In addition, according to this example, the drive division (earlier figures 9) of going into side lowering or hoisting gear 20 is configured in the outside into side room 2.Similarly, the drive division that goes out side lowering or hoisting gear 30 also is configured in out the outside of side room 3.Therefore, the possibility of sneaking in the stove such as wearing and tearing bits that come from drive division is smaller.In addition, owing to disposed side room 2, go out side room 3, so heat is not easy to become separated in flight in stove.
In addition, in this example, vehicle body W1, W2, W3, W4, W5, W6 are with respect to throughput direction substantially vertically, promptly laterally be transferred.Therefore, compared with the situation that vehicle body is longitudinally carried, the stove total length shortens.In addition, when along the lateral transfer vehicle body, because the wall of the sidepiece of adjacent vehicle body is closer to each other, so hot fluid just is not easy to flow.For this point, according to this example, the free degree of the configuration of blow-off outlet 105, suction inlet 103 is higher.In addition, the possibility that the mobile quilt of hot blast hinders in stove is very little.Therefore, conveying method in furnace of the present invention is suitable for the lateral transfer of vehicle body.
In addition, too approaching each other, shown in Figure 3 as described above for fear of the wall of the sidepiece of adjacent vehicle body, the P11 of bar portion of the supporting plate P1 of this example is outstanding forwards, backwards from the P12 of frame portion.That is, shown in Figure 4 as described above, because bar portion support each other, therefore each other, can guarantee to be used to make the interval of the hope that hot blast passes through at adjacent vehicle body W4, W5.
(2) second examples
The difference of this example and first example is to be driven in the stove by conveyer the supporting plate this point in downstream, and the supporting plate that links to each other releasably is joined together this point each other.Therefore, at this difference is described.
In Figure 11, represented to be used in the stereogram of the supporting plate in the drying oven of this example.In addition, for the corresponding position of Fig. 3, represent with same label.As shown in the figure, in the downstream of supporting plate P1, dispose columned engaging protuberance P16.Engaging protuberance P16 is contained by handling part, downstream of the present invention.On the other hand, at the upstream extremity of supporting plate P1, dispose the engaging recessed part P17 cylindraceous that cuts slit.Engaging recessed part P17 is contained by upstream side of the present invention handling part.It is identical or big slightly with the periphery footpath that engages protuberance P16 that the interior Zhou Jing of engaging recessed part P17 is set to.Moreover the supporting plate beyond the supporting plate P1 also has same structure.
Action when carrying for workpiece illustrates with reference to aforementioned Figure 10.Shown in Figure 10 (b), go into side lowering or hoisting gear 20 when rising what carried supporting plate P5, shown in Figure 12 (a), the engaging protuberance P56 of the supporting plate P5 of rising is inserted into from the below in the engaging recessed part P47 of the supporting plate P4 of the upstream extremity wait of moving track 106.By such insertion, supporting plate P4 and supporting plate P5 are attached at together.Moreover supporting plate P4, the P3 that links to each other in stove, P2, P1 have been joined together through same process when carrying in stove too.Be configured in the supporting plate P1 of downstream in the stove with this state, drive by the conveyer at the back side that is configured in supporting plate P1.Shown in Figure 12 (b), the engaging protuberance P26 of the engaging recessed part P17 of supporting plate P1 and supporting plate P2 fastens.In addition, supporting plate P2, P3, P4, P5 also are attached at together mutually by the engaging of engaging recessed part and engaging protuberance.Therefore, the train that these supporting plates P1, P2, P3, P4, P5 erect image are driven the car traction is the same, and side moves with a such spacing of supporting plate downstream simultaneously.Move by this, switch to the state of Figure 10 (d) from the state of Figure 10 (c).Under the state of Fig. 10 (d), when going out 30 declines of side lowering or hoisting gear, shown in Figure 12 (c), the engaging recessed part P17 of supporting plate P1 comes off from the engaging protuberance P26 of supporting plate P2.Come off by this, supporting plate P2 separates with supporting plate P1.
The drying oven of drying oven of this example and conveying method in furnace and first example and conveying method in furnace have same effect.
In addition, suppose to exist each other under the gapped situation at adjacent supporting plate, the driving force that then comes from conveyer at first will be filled up this gap and then be transmitted between supporting plate.Therefore, the transmission of driving force just need be taken time.For this point, if according to this example, then a plurality of supporting plate P1, P2, P3, P4, P5 are attached at together each other very close to each otherly.Therefore, can make driving force rapider and not loss ground pass to supporting plate P2, P3, P4, P5 from supporting plate P1.
In addition, if according to this example, the supporting plate P1 in downstream is directly driven by conveyer in the stove.Therefore, even if the supporting plate P3 (aforementioned Figure 10 (c)) in the middle of in the hypothesis stove waits from toward moving track 106 disengagings, also the supporting plate P1 in downstream can be taken out of outside the stove.That is, can reliably supporting plate P1 be taken out of outside the stove.
In addition, if according to this example, shown in Figure 12 (a), (c), the loading and unloading direction of engaging recessed part P47, P17 and engaging protuberance P56, P26 is set to vertical substantially with respect to throughput direction in the stove of supporting plate as described above.Therefore, in the course of conveying, the possibility that the supporting plate that is joined together separates each other by mistake is very little in stove.
(3) other
More than, the example of conveying method in furnace of the present invention and drying oven is illustrated.But example is not limited to above-mentioned form.Also can with those skilled in the art the form, the form of improvement of the various distortion that can carry out implemented.
For example, in above-mentioned example, in stove, disposed four supporting plates, but the supporting plate configurable number does not limit especially.
In addition, also can will be set at inclination toward moving track 106.This situation, when being set at descending downstream, the driving of conveyer load diminishes.On the other hand, when being set at upward slope downstream, the supporting plate in the stove contacts with each other closelyr, and the transmission loss of driving force diminishes.In addition, when double action track 110 is set at descending, driving wheel 111 (earlier figures 7) be provided with the number just can reduce.Perhaps, become and do not need driving wheel.
In addition, in above-mentioned example,, also can dispose the cylinder that for example moves and be used as drive unit by hydraulic pressure or air pressure though disposed conveyer as drive unit.In addition, shown in Figure 2 as described above in above-mentioned example, in stove above and in the stove below disposed suction inlet 103 and blow-off outlet 105 respectively, but such configuration also can be conversely.
In addition, in above-mentioned example, disposed and made going into side lowering or hoisting gear 20, going out side lowering or hoisting gear 30 of the basic vertical configuration of vehicle body ground lifting, but also can dispose the ramp.This situation also can drive the supporting plate that links to each other in stove and outside the stove via the ramp by conveyer (drive unit of the present invention).So, just can drive the supporting plate that is connected to outside the stove by single drive unit.
In addition, in above-mentioned example, Fig. 5, shown in Figure 6 has disposed minor diameter part P45, P15 on wheel P40, the P10 of supporting plate P4, P1 as described above.But, also can wheel P40, P10 be run in groove at configured slot on moving track 106, double action track 110.
In addition, in above-mentioned second example, on supporting plate, disposed engaging recessed part P17 respectively and be used as upstream side handling part and handling part, downstream with engaging protuberance P16.But this configuration also can be conversely.In addition, also can be not limited to the engaging mode, for example, can dispose and use magnetic force, the upstream side handling part of electromagnetic force, handling part, downstream.So, upstream side handling part and handling part, downstream can be set as identical shape.Therefore, the direction that just can unify a plurality of supporting plates one by one.
In addition, in above-mentioned example, though, can certainly vertically carry with the vehicle body lateral transfer.In addition, drying oven of the present invention and conveying method in furnace are not only after the primary coat operation, also can be used for after the painting process of intermediate layer, be coated with the drying after the finish paint operation.In addition, the workpiece that is transferred can not be a vehicle body also.In addition, also can be used for coated object drying in addition.
