With framework 16 is that benchmark has set lift 24 and 26 respectively at the upstream side and the downstream side of carriage direction, and lift 24 and 26 support plate 28 are subjected to the driving of the drive unit that do not illustrate among the figure can lifting.Be transported the aluminium sheet 14 that comes and risen to the position that to transport with rod-pulling type conveyer 18, and the aluminium sheet 14 of discharging from coated baker 12 is reduced to the position of regulation by lift 26 by lift 24.
Above framework 16, set applying device 30 and drying unit 32 successively along carriage direction, play effect respectively as the coating portion and the oven dry portion of coated baker 12.
The concise and to the point formation of applying device 30 that Fig. 2～Fig. 6 has used perspective representation, and, Fig. 7 has represented to be used to control and drive the structure of block diagram of each member of applying device 30, Fig. 8 has represented the connection layout of sequencer of the control device 60 of control applying device 30, and Fig. 9 represented the wiring diagram of applying device 30.
As Fig. 2 represented in detail to Fig. 6, applying device 30 comprised the coating portion framework 34 that forms shaped as frame.Shown in Figure 1B like that, enclosed (Fig. 2～Fig. 6 has omitted perisporium 36) by perisporium 36 around the coating portion framework 34, in order to avoid coating liquid disperses towards periphery or evaporates.Perisporium 36 is provided with the door that does not illustrate among the figure respectively at the upstream side and the downstream side of carriage direction, and in the time of in aluminium sheet 14 is come in and gone out applying device 30, perhaps under other necessary situations, these doors can be opened.And, be provided with exhaust outlet 38 in the side of perisporium 36, the air in the applying device 30 can be discharged.
As Fig. 2～shown in Figure 6,2 guide plates 40 have been established along parallel the extending across of carriage direction as the inscape of the travel mechanism of ejecting gun 68 described later on the top of coating portion framework 34.Every guide plate 40 upper edge carriage directions can have been installed supporting member 42 movably, stride on this supporting member 42 and have established carriage release lever 44.
And between 2 guide plates 40 (central authorities of width) along carriage direction stride established mobile with cylinder 46.Be convexly equipped with the movable plate 48 that moves along carriage direction from moving with cylinder 46, be installed on the carriage release lever 44.As shown in Figure 7, movable plate 48 is subjected to be transported to the mobile effect with air of moving with cylinder 46 by coating portion control module 52 and by moving with air supply pipe 54,56 from compressor 50, and is reciprocating along carriage direction.
And, movable plate 48 is with position shown in Figure 2, and promptly the downstream side of carriage direction is a position of readiness, and being benchmark with this position of readiness does the motion left to the upstream side of carriage direction, up to terminal location, do return motion from terminal location to the downstream side of carriage direction then.Owing to be provided with the mobile flow that flow control valve 58 is supplied with as the speed control adjustment in the centre of moving, therefore can adjust the translational speed of movable plate 48 with air with air supply pipe 54,56.And in coating portion control module 52, being provided with the mobile of controlled device 60 controls with magnetic valve 62, the time is according to the rules supplied with to move and uses air.
And the part of air that compressor 50 provides is supplied with coating pump 76 by coating portion control module 52, is stored in the coating liquid that apply in the liquid container 78 and passes through coating liquid supply pipe 80 from coating pump 76 supply ejecting guns 68.
Therefore, coating liquid is atomized with air atomizing and is moved with air and sprays from ejecting gun 68.The injection direction of coating liquid is set to towards the direction of aluminium sheet 14, can be with atomizing coating liquid towards aluminium sheet 14 sprayings.As can be seen from Figure 7, in this example, ejecting gun 68 corresponding mobile centres with air supply pipe 70 with two ends in 5 ejecting guns 68 are provided with open and close valve 82, therefore, when the width of aluminium sheet 14 is narrower, can provide for the ejecting gun 68 at two ends to move and use air by closing open and close valve 82, prevent to spray the coating liquid of not wanting.
In the coating portion control module 52, be provided with filter 84 and valve 86, the air that provides by compressor 50 not only can be provided, and can adjust to the quantity delivered of regulation and supply with sequential in the position of regulation.
Upstream side at the carriage direction of coating portion framework 34 is provided with optoelectronic switch 88, so that can detect aluminium sheet 14.And as shown in Figure 7, optoelectronic switch 88 is connected to control device 60.
As shown in Figure 8, constitute the sequencer 90 of control device 60, respectively with workpiece sensing (detecting aluminium sheets 14) with optoelectronic switch 88, spraying begins/stops (coating liquid), (arm) moves and begin/stop corresponding, has delay working contact 92 on each terminal.As also understanding from time diagram shown in Figure 11, with the moment that detects aluminium sheet 14 (detecting workpiece) be benchmark, after this pass through official hour, utilize the spraying of the coating liquid of ejecting gun 68 to be in the state of ON, give coating with magnetic valve 74 energisings.Equally, begin through behind the official hour from the moment that detects workpiece, ejecting gun 68 move the state that (moving of arm) is in ON, give and move with magnetic valve 62 energisings.In addition, though it is contemplated that optoelectronic switch 88 because its structure etc. not only detects aluminium sheet 14 but also detected driven rod 20, but as what can find out from Figure 11, the time ratio that detects each driven rod 20 detects the time weak point of aluminium sheet 14, therefore, control device 60 this detection time than predefined fiducial time of T
0When long, be judged as aluminium sheet 14, detection time is than this time (T
0) be judged as driven rod 20 in short-term, can positively only detect aluminium sheet 14 in view of the above.
As shown in Figure 9, coated baker 12 has power supply indicator 94 (not expression among Figure 1A, B and Fig. 2～Fig. 6), and the operator can know to coated baker 12 supply powers.And, transforming to desirable voltage with transformer 96, this power supply has offered above-mentioned control device 60 (comprising sequencer 90).And coated baker 12 is connecting running ready lamp 102 by automatic/hand change-over switch 98 and move operation switch 100.The operator is by placing ON with the automatic/hand change-over switch, and running ready lamp 102 is bright, and the operator can know that the running preparation is complete.In addition, on the desirable position of wiring, have automatic citrcuit bearker 104, stop electric current excessive.
Shown in Figure 1B, drying unit 32 comprises along the drying baker 106 of the carriage direction configuration of aluminium sheet 14.Have the heater that does not illustrate among the figure in the drying baker 106, switched on by the control of control device shown in Figure 7 60.The energising of heater is set according to the volume of drying unit 32 or the distance between heater and the aluminium sheet 14, made environment temperature in the drying unit 32 more than 60 ℃.And in order to make this environment temperature in the time of keeping 10 seconds more than 60 ℃ at least, the length in the overheated field of heater is set according to the travelling speed of aluminium sheet 14.
Below rod-pulling type conveyer 18, be provided with bar Washing brush 108 as decontaminating apparatus, can clean driven rod 20, remove the coating liquid of attachment removal.
The delustering processing that regards to down with the 12 pairs of aluminium sheets 14 of coated baker that constitute like this is illustrated.
If the operator places ON with automatic/hand change-over switch 98 shown in Figure 9, running ready lamp 102 is bright.Thereupon, rod-pulling type conveyer 18 is driven, and aluminium sheet 14 separates certain interval and is transported successively.
If detect workpiece, as also can understanding, detect behind this workpiece through official hour T from the time diagram of the staircase chart of Figure 10 and Figure 11 with optoelectronic switch 88
1After be in the spraying initial state (with reference to No. 4 horizontal lines of Figure 10), the coating open with magnetic valve 74.Thus, ejecting gun 68 spraying and applying liquid.Coating promptly applies being injected in by the length of aluminium sheet 14 and the time T of travelling speed decision of liquid with the open mode of magnetic valve 74
2After this interior continuing, become spraying halted state (with reference to the symbol 20 of Figure 10).
Begin through official hour T from detecting workpiece
3After be in the state (with reference to No. 9 horizontal lines of Figure 10) that moves beginning, move and open with magnetic valve 62.Thus, movable plate 48 moves forward, move to the upstream side of carriage direction, so ejecting gun 68 also moves to the upstream side of carriage direction.At this moment, because ejecting gun 68 is spraying coating liquid, therefore to aluminium sheet 14 coating liquid coatings.In addition, this stipulated time T
3Be set at and satisfy T
1＜T
3＜T
1+ T
2Therefore, as also can understanding from the time diagram of Figure 11, ejecting gun 68 begins to move to the carriage direction upstream side behind the injection beginning of coating liquid.
In addition, the mobile open mode of magnetic valve 62 of using is at official hour T
4Interior continuing then, stops to move (with reference to No. 24 horizontal lines of Figure 10), and should stipulated time T
4Be set at time T than support arm 64 incoming terminal positions
5Long.And, the traveling time T that is really moving about support arm 64
5(moving forward the needed time), each time is set at respectively: make T
1+ T
2=T
3+ T
4Set up.Therefore, with support arm 64 incoming terminals in, the injection of the coating liquid of ejecting gun 68 stops.
Like this, at ejecting gun 68 spraying and applying liquid and during the upstream side of carriage direction moves, rod-pulling type conveyer 18 is driven, and aluminium sheet 14 is transported with certain travelling speed.Because this carriage direction is opposite with the moving direction of ejecting gun 68, these relative velocities that move become big as a result, can apply effectively.
After because the coating of the coating liquid of 1 block of aluminium sheet 14 is over, optoelectronic switch 88 detects next piece aluminium sheet, after, repeat and the 1st block of aluminium sheet 14 applied identical action.In addition, though ejecting gun 68 must back move back to position of readiness since in this back moves spraying and applying liquid not, if, its sequential is not particularly limited therefore to not influence of later coating.In this example, begin through T from detecting workpiece
3+ T
4Time after, make to move to place OFF with magnetic valve 62, make it back mobile.Though this back moves needed time T
6Also have no particular limits, but this example is owing to make it than moving needed time T forward
5Long, back mobile energy needed is reduced.
Next the aluminium sheet 14 of coated coating liquid is dried by drying unit 32, finishes delustering and handles.Because the ambient air temperature of drying unit 32 inside was kept more than 60 ℃ more than 10 seconds, therefore apply liquid and dried really.
In addition, though the coating liquid that ejecting gun 68 sprays is sometimes attached on the driven rod 20, but since in the contact area that when normal direction is seen aluminium sheet 14, makes 20 pairs of aluminium sheets 14 of driven rod below 24%, therefore can prevent adhering to the neglectful coating liquid of driven rod 20.In addition, though from this viewpoint, preferably make the ratio of this area littler (for example make driven rod 20 thinner or make the interval of driven rod 20 wideer), if but make driven rod 20 meticulous or wide at interval, then often to the excessive localised load of aluminium sheet 14 effects, cause distortion or damage.The present invention has prevented the distortion or the damage of such aluminium sheet 14 owing to make this area than more than 12%.
And, even at coating liquid attached on the driven rod 20 time, these coating liquid also can be removed by enough bar Washing brushes 108.Therefore, coating liquid can not duplicate on the aluminium sheet 14 once more from driven rod 20.In addition, though like this in order to prevent the duplicating to the coating liquid of aluminium sheet 14, the part of cleaning with bar Washing brush 108 only needs the part of driven rod 20 contact supporting aluminium sheets 14 just passable, cleans than this part wealthyer field, and is no problem certainly.
In the above-mentioned explanation,,, be not limited thereto though enumerated the rod-pulling type conveyer 18 that has driven rod 20 as Handling device of the present invention.For example, can be conveyer belt, also can be the device that partly keeps aluminium sheet 14 to transport in a certain direction and so on.If use rod-pulling type conveyer 18, as mentioned above, owing to can easily make contact area to aluminium sheet 14 in desirable scope, more satisfactory.
And, as applying device of the present invention, is coated with application injection part branch and also not necessarily is limited to the above-mentioned mechanism that comprises ejecting gun 68, and also with corresponding as the size of the aluminium sheet 14 that applies object, only quantity is just passable for the quantity of ejecting gun 68.Perhaps,, as above-mentioned example,, can apply effectively owing to make its edge direction opposite move coating on one side with the carriage direction of aluminium sheet 14 though that ejecting gun 68 does not move, is fixed is also passable, thus more satisfactory.
