Abstract
The present invention relates to a kind of method and apparatus of can seam coating, it adopts quick-hardening coating, and the space of post-processing step is reduced.In addition, because coating was in the original state that does not add processing before feed preparing device always, just can become then to applying required fluid state, thereby coating machine itself is also greatly simplified.
Description
The present invention relates to a kind of method that is used for tank body, panel, automotive oil tank and other metallic plate or metalwork weld seam coating, and the device that is used for this class weldment coating.
Different-alloy and (or) single piece of sheet metal of different-thickness welds together new panel or the structure of making, its part has different material behaviors.The space structure that this new compoboard forms through deep-draw is because the material behavior difference has different characteristics in all directions.The bearing part that adopts this method to produce, for example in auto industry, when these parts when running into accident collision, can have predetermined characteristics, need the wrinkle district that the distortion of expectation is arranged here.
For example: automotive oil tank is to together, then along its edge seam by two halves deep-draw part.Usually can manage the space factor of use device, make weld seam in one plane not be three-dimensional curve.
Because this area is known altogether, in order to satisfy new requirement, often different metalworks is welded together.
The common ground of these examples is that after welding, especially behind roller seam welding, weld seam can be protected by welding slag to a certain extent, but it is very coarse, does not add protection and just is easy to be corroded.If there is not suitable coating, normally the newly-generated weld seam of outwash removes welding slag, and oiling like this may some effect.
Therefore, the purpose of this invention is to provide a kind of method and apparatus, can apply coating with the acceptable cost butt welded seam, thereby weld seam is protected.
For clarity, below with the plater of tank body, promptly the coating process to weld seam on the tank body is an example, this just for convenience, but the present invention is not limited to use in the can seam coating.
Metallic plate is preparing to make canister (as metal can, storage barrel etc.) before, at first will be to constituting coating of container inner wall one side or japanning.These metallic plates are through crooked or folding and form container then.To link together through the metal-sheet edges after crooked, folding, for example use the tank body welder, but so coating just has been damaged, coating original in fusion process is removed, and weld seam has exposed car.This makes weld seam be corroded easily, thus after welding, must cover or (with) coat suitable coating.
The continuous coated equipment of known can seam comprises the machine that is installed on the welding arm, in the downstream operation of welder.To wet nitrate paint or powdery paints of this coating machine is coated on the can seam, and it is arranged in the downstream of welder machine direction, is contained on the same process arm with plumb joint.
This coating machine must be designed to be able to processing with average speed 50m/min, the tank body that has just welded that maximum speed 100m/min moves.In the near future, might be up to the speed of 130m/min, and the existing sign of determining shows, also needs faster speed.This means each second that can seam is applied, coating machine need be by more than 1～2m.
For example: the known wet paint method that is coated with, promptly the latter half of a roller is rotated in the pond at lacquer, and its top rides on the can seam in the welding.To be stained with next painting brush from below to top welding by roller.Higher by this method required expense of dealing with problems, but the required device space of this method of lacquering is less relatively.Yet guarantee dry run, but need bigger space, the lacquer that newly is coated with up must be through the heating period oven dry.The assurance wet paint is dried fully and was needed for 15 seconds, and this means needs a post-processing stages that reaches 15～30m.And the release of a large amount of solvents pollutes the environment tapping equipment that need be special.
When powder is used as coating, analogue is arranged also.Powder is with static earlier, is coated onto on the weld seam at the coating place again.Similar with japanning, it also needs sizable cost of equipment.In order to prevent caking, powder must keep cooling with smearing in the process before coating.Also must make the coating static electrification, so that coating evenly distributes in welded joints.Since the characteristic of powder, the environment of a humidity of whole operation process need, but also the post-processing stages of at least a 20～30m of needs.Because powder is a coating under cold conditions,, make the spring fusing so need be heated to more than the fusing point in post-processing stages.It is that coating is thicker that the powder coating also has a shortcoming, and when making large batch of tank body, this may be a deciding factor.For example a tank body production line per minute is processed 500 tank bodies, two classes, and can produce more than 500,000 every day.
Generally speaking, existing can seam coating machine has inherent defects such as equipment complexity and cost height, especially at the coating station, need a very long post-processing stages, and this is undesirable to production line.In addition, also a large amount of hazardous solvents to be discharged, especially under the situation of powder, a large amount of raw materials be consumed.
Therefore, the objective of the invention is to propose the method and apparatus of can seam coating, in this way, can save last handling process, at least can major part save, maybe the coating post-processing stages can be compressed to the shortest, have only several meters long.
The invention provides a kind of coating that is in a liquid state when applying carries out coating to the weld seam of tank body, panel, automotive oil tank and other metallic plate or metalwork method for this reason, it is characterized in that: this coating is made up of one or more compositions, the short time promptly solidifies after applying, and does not need further processing to harden fully.
For realizing above-mentioned method, the invention provides a kind of device, it comprises that frame, drive unit, control system, weldment are (as panel, automotive oil tank and other metallic plate or metalwork, especially tank body) induction system and paint coatings device, it is characterized in that it has one to carry original state coating (semi-finished product especially, and/or solid or non-solid composition) feed system and coating is modulated to the feed preparing device of suitable coating state, feed preparing device is right after in the front of station 48, and coating is painted on the weld seam at station 48.
According to above-mentioned technology, use a kind of coating that after the weld seam coating, just can solidify in very short time, thereby do not need after-treatment device.This can make the design of tank body welding production line that remarkable progress is arranged, and tank body coat system itself is also greatly simplified.After coating was solidified, pansclerosis (if desired) can be finished in the way that enters following one tank body manufacturing procedure.
In one embodiment, if coating is made up of hotmelt substance or melt adhesive, following advantage is arranged then: except that reaching original purpose, post-processing stages can save fully.This hot melt material is also referred to as thermographic compound, or melt adhesive, and this all knows in adhering technique, is commonly used to two workpiece be glued together or link together.This hot melt material is employed in the bonding of automobile, weaving and packaging industry especially on a large scale.
This hot melt material is coated on the can seam, can very fast hardening by cooling, because tank body can in seconds take away the heat of welding zone, and do not need assist cooling, thereby just do not needed post processing yet.
Even under the situation that is requiring further heating, for example: for promoting the polymerization or the cooling velocity that slows down of coating, length is arranged, and only several meters bringing-up section is also just enough, this is that the equipment of present this area can't be compared.
According to another embodiment of the invention, because coating is transported to the coating place with insensitive original state, complexity at coating place equipment can greatly be simplified, the state that particularly each composition of hot melt material or multi-component coating can be original is carried, is stored and handles, and unlikely going wrong.
Thereby except realizing initial purpose, also have following advantage: between feed preparing device and coating position, do not need special safeguard measure to prevent to paint differential hardening or foaming, or the powder caking.Also have, use hot melt material, also do not need coating to be transported to the coating position, so just eliminated the danger that the harden zone is provided in the coating that provides by heating hose.Not so because feed preparing device and coating position will be at a distance of several meters, especially the maintenance of can seam coating machine and (or) during welding equipment maintenance of its upstream, flexible pipe is carried the danger that exists caking and sclerosis.
Now by present invention is described with reference to the embodiment with the form of giving an example.
Following many embodiment relate to the can seam coating.Plater can be used for the coating of panel or automotive oil tank weld seam, does not need it is done any repacking, even need also very little.Main repacking is to arrange conveying device according to the concrete condition that is coated with workpiece, and these conveying devices are that this area is in common knowledge, and to clean required processing with water similar to weld seam, just replaced brush device for cleaning with the plater among the present invention.

Fig. 3 b is along the profile of A-A direction among Fig. 3 a;
What Fig. 1 represented is that welding equipment (1) and coating (2) link together.
Welding equipment organic frame 3 has volume round belting 4 on it, welding arm 5 and welding roller 6,7.The vertical deviation adjusting device of roller 6 is welded in the top as we can see from the figure.The hanger bearing 8 and the Z type rail 9 that also have welding arm 5 on the figure.Just spool the tank body 10 of also opening mouth and be positioned at the volume round belting, mobile on Z type rail 9 near the tank body 11 of welder.Tank body 12 is in the welding position.
The frame 21 of tank body coating machine 2 is bearing on the pedestal 20, and an end 22 of frame 21 is fixed on the welding arm 5.Be used to carry the induction system 23 of the tank body that has welded to be arranged in frame 21.
Go back having heaters 28 and 29 on the frame 21.Heater 29 is assisted heating devices, and heater 28 and 29 mainly heats the weld seam on the tank body 54.
For clarity, all drivings and the control device of tank body coating machine have been omitted among the figure.Driving and control device are traditional structure, are installed on the frame 21.
As half-finished coating 30 with wire on reel 31.The induction system 35 of coating comprises the roller 36 of pipeline material 30.For coating 30 is advanced, induction system 35 also has a driving wheel 37 to be contained in the front (in feed direction) of plater 40.In application device 40 inside feed preparing device 41 is arranged, and be used for depositing fluidised form coating with material-stored pool 42.
The coater that is made of nozzle 43 communicates with material-stored pool 42 by pump, for fear of confusion, has omitted pump configuration among the figure.
The tank body coating machine 2 that Fig. 2 represents is identical with Fig. 1 type, and just feed preparing device 41 is through repacking.
The chamber 44 of getting the raw materials ready is arranged in the feed preparing device 41, and the wire coating 30 of the inside directly feeds through driving wheel 37.This chamber is by heater 45 heating, and Electric heating, microwave radiation or other form are taked in heating.Auger conveyor 46 among the figure is transported to nozzle 43 with the pressure of necessity with coating.
The auger conveyor here is equivalent to a pump, is used for carrying coating.The mixed process of multi-component material or the fusion process that contains thermoplastic composition material are finished in space 44.Correspondingly, when requiring to mix gradually with fusion process or increasing pressure, can realize by changing screw diameter and/or axle diameter and spiral slope thereof.
What Fig. 3 a represented is the tank body coating machine 2 of type shown in Figure 1, but the feed preparing device 41 here is through repacking.
Feed preparing device 41 has an endless belt 52 to carry out transmission around two rollers 50,51 of getting the raw materials ready, and this band has constituted the device 60 that coating is taken to coating commissure 54.Get the raw materials ready roller 50 and 53 common cooperations and play the driven roller effect, wire coating 30 is taken on the endless belt 52, coating also can be finished preform by roller 50 and 53 simultaneously.The roller 51 of getting the raw materials ready is pressed onto coating 30 on the tank body 55 that just is sent to herein.Tank body itself bears this pressure by supporting roller 56, and wire coating 30 just has been shaped like this, sees Fig. 3 b.
Fig. 3 b is illustrated in the sectional view that common contact point was cut supporting roller 56 and roller 51.Provided weld seam 57 among the figure, the wire coating 30 of shaping and rotating endless belt 52.
Owing on the can seam overlap is arranged, need cover step 58 by the accumulation of coating 30, because physical cause, coating has the trend of overflowing along step 58 edges 59 side direction in fusion process, thereby reveals.
When bonding machine 1 work, metal slabs enter volume round belting 4, and tank body 10 just here is rolled into.The tank body of newly spooling is centered around wire coating 30 outsides of sending by roller 36.Do not provide the conveying device that tank body 10 that promotion just spooled moves among the figure, the edge of tank body (being the tank body 11 among Fig. 1) slides along Z type rail 9.Continuing to advance on welding arm 5 in hanger bearing 8 backs of tank body 11 by welding arm 5, cracks up to welding by welding roller 6,7 in tank body 12 positions.Tank body 12 still on coating 30 and welding arm 5, becomes a cylinder but sealed after the process welding.
After the tank body 12 that has just welded is sent from welding equipment 1, access by the belt conveying device 24 of tank body coating machine 2.Because tank body 12 has sealed into cylinder, all act on the scope that the parts that (comprise that effect in welded joints internally) on the tank skin all are positioned at frame 21 internally.End 22 is permanent the connection with welding arm 5.When tank body 12 passes through conveying device 24,, mainly be to make weld seam keep a higher temperature, otherwise can after welding, be cooled gradually by heater 28 heating.Tank body 12 is accessed by conveying device 25 then, carries it by plater 40 by this device, and coating is allocated in feed preparing device 41, and technology is as follows:
Coating 30 is pushed feed preparing device 41 to by driving wheel 37, is heated the fluid state that is fit to carry out coating here.
Under the situation that adopts multi-component coating, for example can mix to reach required state by 44 pairs of each compositions in chamber of getting the raw materials ready of feed preparing device 41.If contain a kind of hotmelt substance in the coating at least, this hotmelt substance can be heated fluid state by heater 45.Then by pump (omitting among the figure for clarity) will coating coating be pumped into the nozzle 43 of plater from material-stored pool 42.As long as the valve 47 of nozzle 43 is opened, the fluid-coating of the confession coating by pumping just is coated onto by belt conveying device 36 by nozzle 43 and sends here just by on the tank body 12 herein.The action of the action of pumps and the discharge system 35 that drives by driving wheel 37 in the action of coordinating mouth 43 jointly by the drive unit (omitting among the figure for clarity) and the control system (omitting equally) of tank body coating machine 2, the conveying of tank body 12 and the chamber 44 of getting the raw materials ready.
Whole like this process comprises original state coating is made the required fluid state of coating in the application point front, is coated onto on the weld seam immediately.Make can seam heating by heater 29, so that inhomogeneous coating of newly being coated by nozzle 43 or the solid coating that is coated on the tank wall by endless belt 52 flow.
Preferably nozzle 43 is also heated, so that operation is when interrupting, the hot melt material can not cool off.
When hotmelt substance needs polymerization, adopt the back heating also to suit, the duration of polymerization process is more longer than the time that weld seam cools off naturally usually.
When the coating process was coated onto on the can seam at coating, the coating distribution to weld seam finished the back fully.Coating hardens in the course of conveying of belt conveying device 26.Sclerosis or post-curing can be finished in the process that enters next machined station fully, without any need for post processing.
An advantage of above-mentioned tank body coating machine is, the shared length of equipment itself only is 1/3 or 1/4 of conventional equipment length, and this is a very big advantage in the total arrangement of production line.And because coating 30 can store, handle by original state (as semi-finished product) before coating place, the design of coating machine itself can greatly be simplified like this.There are partially hardened and agglomeration problems and the complexity of taking, expensive device (as hotmelt substance is transported to the equipment of feed preparing device 41 via welding arm 5 by heating hose, from volume round belting 4 by roller 31) can save at the coating such as powder and paint.
Especially the said equipment can be processed the less tank body of diameter.
These advantages also can be provided by the embodiment according to Fig. 3 a and Fig. 3 b.
Wire coating 30(also can be banded or other cross sectional shape) move feed preparing device 41 to by roller 50 and 53, extruding between coating roller 51 and tank body 55, shaping when on the endless belt, carrying.Because the effect of heater 28, tank body keeps heated condition, and the coating 30 that contains hotmelt substance like this begins fusing immediately.Can help the coating fusing by auxiliary heater 61, adhere to rapidly on the tank body 55 without a doubt.Also can make the coating fusing from inside to outside, can behind roller 51, corresponding device thereof be set for this reason.
Another advantage of this shaping is, do not needing under high the technical sophistication degree and condition of cost, and coating 30 can reach Optimal Distribution in welding.From Fig. 3 b as can be seen: there is step 58 commissure at the plate overlap joint, and coating forms accumulation on its corner angle 59, and when coating melted, its corner angle 59 can be covered fully like this.
Another advantage of present embodiment is, do not need to make fluid-coating to remain on the heater and the pump of coating state, certainly, also do not need nozzle 43.
Present embodiment can provide solid coating, and the composition of tank body coating machine 2 is simpler.
Certainly backing roll 56 functions also can be finished in the embodiment previously described.
The not expression in the drawings of a kind of situation is arranged, and the coating that promptly can adopt not only a kind of one-tenth to be grouped into is allocated in feed preparing device 41, and it allows to use the coating of being made up of various compositions.
Be not contained on the reel 31 if coating 30 is not the semi-finished product with the optimal cross section shape, can adopt building mortion, finish shaping operation as adopting roller 50 and 53.
Also can coating be directed to 48 fronts, coating position, coating is modulated with endless belt 52 further by guider.Modulation can comprise by heating makes upper surface softening, or adds new paint ingredient by distributor, or comprises a device that is used for adding softening agent.
Outside the order of presentation except each device (drive unit 35, feed preparing device 41, application device 40) of diagram, also can rearrange, shower nozzle 43 is right after in the back of welding roller 6,7, like this, heater 28 just can save.Coating can through being arranged in backmost the guide roller of (throughput direction with tank body is as the criterion), being carried along the direction opposite with the tank body throughput direction and get back to application device at first by aforesaid each device.
Though the exemplary embodiments of this plater is the coating of can seam, the present invention is not limited to the coating of can seam.
Method of the present invention also can be used for the coating of metal decking (as: deep-draw panel), and its purpose is the same substantially with solution.
