Fig. 2 is the layout drawing with the opposed spray gun of axle.
Fig. 3 puts the spraying object that revolves round the sun and the layout drawing of spray gun on axle.
The specific embodiment
Fig. 1 implements device one example that spraying method of the present invention is used.The 1st, spray robot is according to the actuating signal from the control device of other setting, Yi Bian Yi Bian be installed in the spray gun of support arm 2 front ends and can freely move and spray.In this embodiment, spray gun supporting mass 3 with this support arm approximate vertical is installed, spray gun 4A, 4B is installed in the both sides of this spray gun supporting mass 3 at the front end of support arm 2.These spray guns on spray gun supporting mass 3 according to the holding function of spray robot 1 and freely move up and down.
In addition, relative its of spray gun supporting mass 3 is installed in central part on the spray robot 1, can stretch symmetrically in its two ends, and the interval that is installed between the spray gun of both sides can change.Telescoping mechanism can be selected in the prior art scope, for example utilizes the screw of left and right sides opposite pitch, or link mechanism etc.Its action is identical with the control signal of spray robot, is sent to servomotor to be controlled to necessary interval.Present embodiment is that 2 spray guns are set in the both sides of spray gun supporting mass 3 as shown in the figure, has 4 spray guns to move simultaneously in both sides, can improve spray efficiency.
The spraying object puts on the runing rest 6 on the conveyer belt 5 that is positioned at spray robot 1 the place ahead and is transported to spraying position.Axle 7 is set on conveyer belt 5 at certain intervals, and rotating driving device 15A and 15B that each axle 7 is arranged on spraying area drive and rotation automatically.As for rotating driving device, the friction roll portion contact that can adopt axle is driven by drive unit and transmits the method for revolving force during the belt of rotation.As shown by arrows, the direction of rotation of rotating driving device 15A and 15B is opposite each other, and the rotation of axle is the boundary with the pars intermedia, does opposite each other rotation in each zone.
Each axle is equipped with runing rest 6 as shown in Figure 3, is provided with 4 spraying object supporting masses 8 around the runing rest 6, and the spraying object W that embeds spraying object supporting mass 8 is around axle 7 revolution.The quantity of spraying object supporting mass 8 or shape etc. can preferably can be changed runing rest 6 simply according to the size and the change of spraying condition of spraying object.
As previously mentioned because spraying object revolution, on one side so spray gun is controlled according to direction of rotation on one side and pivot between deviation distance S spray, can improve spray efficiency and improve presentation quality.In addition, if just from same direction spraying, can not opposite face fully be sprayed certainly, therefore also want reverse rotation to spray, at this moment above-mentioned deviation distance S departs from the center round about.
Because the present invention is simultaneously to spraying at both direction rotary spraying object, and be to utilize the spray gun that is arranged on the spray gun supporting mass both sides on the spray robot to spray simultaneously, therefore the position of the spray gun that places two rotary areas is departed to opposite each other direction, adopt a kind of spray gun spray gun supporting mass at interval that changes for this reason.
The position relation that moves spray gun 4A, 4B set on the spray gun supporting mass 3 that reaches spray robot 1 of aforementioned conveyer belt 5 and axle 7 as shown in Figure 2.For example from the left side of spraying area move to axle 7 that the conveyer belt 5 on right side sets up do on the left side of pars intermedia and right side before and after opposite rotation, each spray gun 4A, 4B in the scope of arbitrary rotary area all with spray object (runing rest) and be provided with opposed to each other and move.
Usually, when carrying out the spraying with the irrelevant to rotation direction of support, spray gun is disposed at pivot, but when the spraying object that revolves round the sun like that at the embodiment of the invention, if spray gun, then can spray the left and right side and the positive thickness inequality of object facing to pivot.And if spray gun be configured in over against the spraying face the position on, just can improve spray efficiency and presentation quality, on the contrary, if the direction of fleeing from spray gun is sprayed, then not only can reduce spray efficiency, also can be stained with the corase particles of many sprayings and cause presentation quality to worsen.
Thereby, as shown in Figure 2, spray gun is arranged at the runing rest 6 in left side and from pivot depart to the right, at the pivot 6 on right side and depart from left from pivot.In addition, when different spraying objects or spraying position cause from the deviation distance of pivot not simultaneously, the interval X of spray gun that can be by making both sides stretches and regulates.In addition, while, also will in course of action, change the interval of the spray gun of both sides spray when improving spraying effect by spray gun is moved laterally from the central side of rotation.These action control signals that move available spray robot are controlled.
Spraying area around the conveyer belt 5 is provided with the spray booth 10 as spraying area, prevents in the dust inlet chamber pump-down process of spraying etc.
Below describe in detail with the actual spraying of carrying out of said structure.As shown in Figure 3, on runing rest 6 set on the axle 7 of conveyer belt 5, put 4 spraying objects respectively and also be sent to spraying area successively.The spraying object is revolution to the right before being sent to the central authorities of spraying area, the spray robot 1 that has been set in advance working procedure simultaneously to below it, positive and above spray.At this moment 2 spray gun 4A with the left side spray the spraying object that puts on 2 runing rests (the 1st batch of 2 supports) simultaneously, spray robot moves to other 2 runing rests (the 2nd batch of 2 supports) and locates then, below the spraying object that puts on it, spray, and then move to other 2 runing rests (the 3rd batch of 2 supports) and locate, below the spraying object that puts on it, spray.
Then when the front is sprayed, be that order according to the 3rd batch of 2 supports, the 2nd batch of 2 supports, the 1st batch of 2 supports sprays, order according to the 1st batch of 2 supports, the 2nd batch of 2 supports, the 3rd batch of 2 supports sprays top at last, so far, the spraying of left side rotary area finishes.Adjust line speed and spray time then, the 1st to the 3rd batch of this 1 pack support sent into the reverse rotation zone on right side.
The spraying object that is admitted to the right side rotary area is done reverse rotation, and with the state revolution of previous opposite spraying facing to the spray gun 4B in rotating shaft left side.
That is, the spraying face of failing fully to obtain spraying at the rotary area in left side is sprayed at the right side rotary area, thereby forms overall uniform spraying face.Under this state, finish identical spraying with aforementioned spray gun 4A.Certainly, during spray gun 4B implemented spraying, next group spraying object carried out same spraying by spray gun 4A, finishes spraying so successively.
Be to be 1 group in this example with 6 supports, respectively carry out finishing after 6 sprayings, in order to make the displacement minimum of spray robot between each runing rest,, make spray robot return origin position when finishing 1 group of spraying by setting line speed, spraying quantity, spray time.
The present invention can spray at a necessary position to the spraying object, and can interrupt spraying in the process that moves to next spraying object or next spraying face by using spray robot, can only do necessary spraying thus, can improve spray efficiency.
The method of utilizing spray robot to do the axle spraying has following effect.
When the present invention sprays the spraying object that revolves round the sun on the live spindle on the conveyer belt that transmits continuously, the direction of rotation of axle just is divided into by spraying area, reverse rotation, in order to realize synchronization action at 2 spraying areas, make the ejection position of the spray gun that is loaded on the spray robot adapt to the direction of rotation of the spraying object that revolves round the sun because of axle, it is worked in the best condition, so that the spraying object that transmits is successively sprayed, can spray a plurality of spraying objects that are transmitted simultaneously, thereby can be not lavishly, spray continuously, can enhance productivity.
In addition, for the spraying object that revolves round the sun with axle because of forward and reverse rotation opposed symmetrically, the spray gun that utilizes the flexible of spray gun supporting mass and will be loaded into two zones is adjusted at the optimum position all the time, therefore the turntable in the time of can compressing the axle spraying to greatest extent during the blowing out the position change and adopt the spraying of turntable type axle of the direction of rotation conversion of necessity, spray robot such as moves at the required time, can reduce the spraying intermission to greatest extent, thereby can enhance productivity.Adopt the embodiment of the invention, yield of unit time is 2～3 times when adopting the turntable type spraying method.
And can use spray robot continuously the axle on the conveyer belt to be sprayed, and therefore to compare with the occasion of using fixing spray gun center roller to spray in the past, each sprays object only need be with about 1/5 coating, thereby saved coating significantly.Compare with the continuous ejection coating of automatic axle spraying method, the present invention is by the best ejection of the spraying Object Selection position at revolution, coating be can only spray where necessary, and can best ejection distance, ejection position and spray angle be adjusted the spraying object, but and ejection while following the trail of.
In addition, in order to improve implementation result of the present invention, also can be used in combination with various device, for example on the path of each spray gun, volume control device is installed, can realize more stable spraying, the colour changing device can be combined with control device, automatic cleaning of spray gun airhood etc. is combined with the control of spray robot, can further improve spraying effect.
As mentioned above, the present invention can realize output height, the spraying that spray efficiency is good, outward appearance is good, is suitable for using high grade paint to produce in batches, can reduce cost extremely effectively.And can reduce the discharge of coating, and reducing discarded object, efficent use of resources helps to improve environment.
