Description

Spray booth

Technical field

The present invention relates to when carrying out application, to be used to capture the spray booth of the coating mist that processing splashes because of spraying.

Background technology

Spray booth (hereinafter referred to as paint booth) is to be used to attract to capture do not have along with spraying attached to the coating mist on the coated object, avoid it once more attached on coated object etc., and be used to reduce emission of harmful substances that the surrounding environment that comprises the coating mist is made a very bad impression indispensable equipment.What spray in paint booth is not attracted by the air-flow towards exhaust gas treatment device attached to the paint particles on the coated object, still, and because of the position of the wall of spray direction, turbulent air flow or air-flow contact etc. not avoiding it attached on the indoor wall.

The coating that adheres to uses through long-time, or forms the dope layer that has solidified because of spraying surplus on the wall of paint booth, can be attached on coated object or operator and other devices, and formation stain and produce baneful influence.Particularly attached on the coated object, cause application bad, must often make the paint booth cleaning attached to the coating on the ceiling can fall., will regularly sweep for this reason, can interrupt causing production efficiency because of work like this and reduce, and increase operator's burden.Application automation and continued operation are to boost productivity indispensablely, under the situation that the progress of application automation and control significantly improves, subsidiaryly carry out the necessary follow-up of keeping the environment equipment needed thereby and seem insufficient.

ADHESION OF PAINTS differs widely because of various application conditions, to carry out every half a year under the few situation of usage frequency, all to carry out weekly and the situation of continued operation is next, situation has various, but, no matter which kind of situation is all very big to the burden that the influence and the operator of productivity ratio cleans.In order to alleviate the cleaning operation, generally be on wall, to coat the grease that is easy to remove in advance, as disclosed countermeasure in the special fair 07-012454 communique of Japan be, covering is provided with the wall sheet material of oil membrane, sticking film paper etc. in advance, the paper pasted etc. is peeled off together polluting to a certain degree stage, thereby saved the operating time.

On the other hand, in order to eliminate the most debatable coating adhering to the ceiling face, prolong and clean the interval of operation, device by filter ejection air-flow is set on the ceiling face, adopts that consider can be attached to the equipment on the coated object to indoor dust etc. from paint booth front openings portion because of supplying with fresh air.Particularly, for the application of the precision equipment of in recent years electronic message unit representative, to require senior accurately machined painting dressing automobiles to wait be integral equipment.

In addition, paint booth is communicated with the industrial building mostly, attracts the interior air of factory building and it is discharged into the outside.Therefore, also will be discharged, and can cause huge energy loss like this with air in the operating room that paint booth links to each other through air-conditioning.

Usually, the air-flow in application zone flows with the speed of per second 20cm to 1m, and supposing has 10 square metres opening, and the air of regulating through air-conditioning that has hundreds of cubic metres in a minute is discharged into the outside, and this is a very big problem.As countermeasure, adopted air circulation after the coating mist handled to import and reduce the method for actual capacity, supply with and the different fresh air of room air by force through the air-conditioning adjusting, mainly be air that extraneous air has been purified through filter as the air that imports paint booth, thereby reduce the loss of Air Conditioning.

The air-conditioning of paint booth is having under operator's the situation, beyond any doubt the problem that can not avoid healthy aspect and keep the environment aspect.And, even full automation carries out the occasion of application operation, the condition of coating or coated object nearly all is to be set under the condition near living environment, also is necessary condition in order to seek the stable of coating quality and to avoid application bad, maintaining certain humiture environment.Particularly, stability is absolute condition for the application condition of the application of the precision equipment of electronic message unit representative in recent years, we can say that room conditioning is its primary condition.

As for the method that exhaust gas recirculation is utilized, the processing that need fully carry out discharged air is air feed again, and the equipment aspect needs the great equipment of scale.That is, must allow common emission gases is purified, it is handled thin below horizontal of smell, also can not impact human body or application even turn back to paint booth once more, its processing cost is very big burden, does not form enough countermeasures now.Much less, the supply of the fresh air of outer gas, the variation of its humiture etc. is big, if consider the management of application condition, the air feed without humiture is adjusted is not suitable in stable application of coating quality and the accurate application industry.

On the other hand, the simplest method as the amount that reduces discharged air, can consider to reduce the opening of paint booth, but, consider openings of sizes is allowed some leeway to coated object for the convenience of operation, particularly in the complicated again application of precision etc., requirement all will be carried out uniform application to complicated shape, inside, depths or corner portions located, under these circumstances, need spray from various directions, require thus to spray towards paint booth on a large scale, local opening then can't be tackled.

In addition, though also have by pipeline and control the required air of in paint booth, supplying with, but, as the technology that attracts to the indoor air feed broader, from ground to do to represent, the part air-flow is regulated than the part of ceiling face, though also take the distribution of indoor air-flow into account by the device that disposes the air supply opening of patterning (パ one Applicationization) in the air feed side, but these are adopted as the part of systematized equipment.But, in this occasion, indoor air-flow, though for example the occasion of carrying out application at the large-scale coated object that automobile etc. is set can produce suitable air-flow around coated object, but under the situation of small-sized coated object, indoor air-flow concentrates on a part, so insufficient with the attraction of spraying mist around the coated object.Therefore under these circumstances, generally rectifying installation is set, constitutes the air-flow that can form uniform required flow rate on the whole in ceiling portion.

And then, as the disperse device of coating mist of effective processing, in Japanese Patent Publication 54-22461 communique, disclose the such technical scheme of partial exhaust gas device has been set in a part.But in the case, the attraction of exhaust apparatus is partly separated, and the opening of placing the paint booth of coated object does not change, and does not constitute the structure that reduces whole capacity.

Generally speaking, when in the paint booth of opening the coated object of indoor placement being carried out application in front, the operator sprays from the front towards the exhaust outlet of being located at the paint booth rear portion.Therefore, the occasion in the side or the back of application coated object is just rotated coated object and is sprayed towards face side, and then has the occasion of male and fomale(M﹠F), is to spray from oblique.This also is the same for top and bottom, and the complicated shape that has slot part etc. just needs to carry out these spraying operations in order to implement uniform application.

In the prior art, in view of operator's the environment or the reason of operability aspect, extensively carrying out though carried out the situation of application by the automatic painting device of robot representative, above-mentioned basic operation is identical, is to spray around the place ahead of coated object.And from the oblique occasion that sprays, then towards the wall of paint booth, the result is not attached on the wall attached to the so-called excessive spraying on the coated object (オ one バ one ス プ レ one).Therefore, wish that paint booth is enough wide, the distance of coated object and wall attracts so that just be deflated stream before the coating mist arrives wall, yet can cause paint booth to maximize like this, strengthens facility load.

The little occasion of distance between, wall narrow and the coated object at paint booth, the coating that adheres to gradually on wall accumulation, dirty and to around or coated object make a very bad impression.Particularly, it is bad to fall the application that can cause coated object attached to the coating on the ceiling face as described above, therefore regularly cleans unavoidably, causes productivity ratio to reduce or operator's burden.

For this reason, consider with paint booth normally to be arranged to as all feasible size of any coated object of object, do not use under the situation that causes very big waste because of coated object does not coexist from scope as the non-painting object of object.That is often be to exceed needs ground under the state that the air current flow of the pump-down process of paint booth integral body, to proceed operation.

Summary of the invention

The automatic application of corresponding industrialization development is provided with the paint booth as environmental unit that can not interrupt operation uses and plays good effect under the situation of pursuing productivity.That is, even seek to improve automation, production efficiency by the exploitation coating equipment, do not shut down if do not follow the attendant equipment that uses it also must allow coating equipment itself have a rest, the result can cause productivity ratio to reduce.One of problem of the present invention just provides a kind ofly need not interrupt application operation and just can carry out required cleaning apparatus operating.

To make its stained problem on the coated object in order solving to fall, to obtain before falling, to clean operation in good time, and the equipment that can alleviate the burden of cleaning operation is another problem of the present invention attached to the coating on the paint booth wall.But also can list, the cleaning operation is automatically to be used continuously, the discarded coating that cleans out, dust etc. are handled with the exhaust gas treatment device streamlined of paint booth, solve the problem of the more high efficiency paint booth of acquisition thus.

And then, the occasion of paint booth is being set, be provided with if reckon with the coated object of various size, little coated object can't be avoided waste as described above.And, in application operation coated object the operation of complicated spray gun just to spray from a plurality of directions, for this reason, the scope of operation increasing thereby require paint booth self enough big.For this reason, not only can be because of discharging the air off-energy suitably regulated, and can reduce and comprise the coating mist treatment effeciency that is undertaken by the air of the coating mist of rarefaction to what a large amount of exhausts were accompanied by.

The present invention can solve the waste of cutting down capacity, prevent that above-mentioned energy loss or coating from adhering to the problem of the stained paint booth that brings, its result can obtain energy-conservation and keeps painting environment, high-quality and can carry out application stably, the paint booth that can use under effective capacity state.

The present invention is in order to address the above problem, a kind of spray booth is provided, described spray booth as the peristome of sending into, be provided with coated object, is disposing the suction path that with the exhaust gas treatment device of coating mist be communicated with this peristome rear portion side in opposite directions with the front of paint booth; The face of ceiling at least in the wall of described paint booth, the surface of the described suction passage side disposed chamber inboard from described peristome to the rear portion is screen pack movably, adheres to the retracting device of coating in this suction passage side setting.Screen pack rolls thereby can make the part attached to the surface to move to the paint booth rear portion in rear portion side, hugs to remove in the position of leaving the application operation and waits by retracting device adhering to the processing of coating.

Can be the rotary conveyor formula by making the movable filter net, and use by hugging except that retracting device cleans the place ahead that the screen pack that makes the surface become clean conditions is admitted to paint booth once again., be located in the exhaust gas treatment device of coating mist as the scraper plate of hugging except that retracting device at the paint booth rear portion, send in the exhaust gas treatment device, can handle simultaneously with the processing of coating mist thus hugging the coating material grounds of removing.

In addition, the present invention is in order to address the above problem, peristome in the front of paint booth is provided with wall and at its a part of opening, by the air stream that attracts from opening to the coating mist handle, exhaust, become the formation that reduces capacity thus, peristome that can mobile paint booth front can be set in the appropriate location with peristome corresponding to variable factors such as the size of the coated object that is admitted to, shape, positions.

In addition, the movable plate that covers peristome can constitute one by one movably, can change the area of peristome, thus, for the change of the size of coated object or shape etc., perhaps, also can be set in suitable opening portion for the variation of the opereating specification of coating machine.In addition, also the processing air quantity of exhaust apparatus side can be regulated if desired, economic operation can be carried out thus always corresponding to the area of peristome.

The coating mist that in paint booth, disperses during application, much attached to around wall on.At this moment, at least attached to the coating on the ceiling face in the stage that is attached to a certain degree, adhere to face and be pulled to the rear portion, remove and easily get rid of hugging by the position that does not influence application.Usually,, it is arranged to transportable screen pack for being drawn back, be to establish the film of flexibility being located between the cylinder at two ends to open, by suitable slewing equipment the drum segment of part to the rear portion towards paint booth moved, the removal apparatus of hugging by scraper plate etc. is wiped it off, under the state of not falling paint booth, clean, via the cylinder of paint booth front side, form the ceiling inner face in the paint booth once again.

Remove operation even in application is carried out, also can hug at any time, can manually carry out while confirming, perhaps also can be automatically be undertaken, can improve the operation disruption that causes because of cleaning or operator's burden greatly by the action of the scraper plate of control operation at certain intervals.And hug the coating material grounds that removes and carry out with the material slag recovery that captures treating apparatus, need not carry out once more, eliminated trouble.

In addition, according to the present invention, can not change the size of paint booth, as long as under the state of keeping the operating area that needs, dwindle the peristome of front, the air-flow that is deflated device attraction is flowed into from limited scope, flow velocity with needs attracts the coating mist that coated object disperses that it is attracted to treating apparatus on every side, carries out high efficiency processing.

Promptly, because the coating mist that can will disperse by the smaller amounts of process air by peristome is handled with the state of high concentration, so carrying out the device of post processing also need not be as of the prior art, employing by a large amount of rarefaction of airs jumbo treating apparatus, can make equipment miniaturization.

And then, because moving or being changed to automation of peristome carried out, thus, even in the occasion of using paint robot or automatic painting device to operate spray gun automatically, also can make the position or the size correspondence of peristome corresponding to its action, therefore, can not hinder the application operation, can carry out the application that significantly reduces capacity under the situation of operability keeping.And the integral body from paint booth is not taken into air, but sucks limited air from peristome, and the discharge of the air that therefore can suppress in the operating room as described above by air conditioning seeks significantly to reduce energy loss.
