Description

Spraying equipment
Technical field
The present invention relates to a kind of spraying equipment that the spraying object is sprayed.
Background technology
Sprayed on material can be a particularly paint vehicle of a kind of liquid such as pigment, or a kind of spraying powder, its be injected on the spraying object and through heat treated with spray object and engage for a long time.Injection apparatus can be the automatic spray gun that pistol or machinery keep.
German patent specification DE 34 02 945 C2 (corresponding to GB 2 153 260 A) disclose a kind of hand-held electric spray gun that the spraying object is sprayed, and which comprises at least a high-voltage electrode, are used for sprayed on material is carried out electrostatic charging.One voltage display is set on electric spray gun, and it has viewing area backwards, according to the relevant voltage display light signal of high-voltage electrode.The electric spray gun that is constituted can spray the spraying powder or spray spray coating liquor.The viewing area of voltage display backwards, when the operating personnel of hand-held electric spray gun observed spraying process, operating personnel's head needn't be towards spray bundle and the object that will spray.In the embodiment that the document is described, the high-voltage generator that voltage display and is arranged in the electric spray gun is connected.One light emitting diode is connected with the elementary of transformer through resistance, connects a cascade circuit that produces the dc high voltage of high-voltage electrode on transformer secondary.Transformer and light emitting diode are arranged in the transformer housing, and this transformer housing is arranged on the electric spray gun and is removably fixing with electric spray gun.But since be arranged in the transformer housing transformer be arranged on electric spray gun in cascade circuit between be connected by electric lead, can not apace the transformer housing be separated with electric spray gun.Voltage display can have incandescent lamp, voltmeter or the similar alternative light emitting diode of optical display unit with voltage change.High-voltage generator is disposed thereon or wherein have or do not have the advantage in the electric spray gun of high voltage transformer to be, provide electric energy not need high-voltage cable from control device to electric spray gun, and only needing low-voltage cable, the weight of low-voltage cable and hardness are more much smaller than the high-tension cable.High pressure generator was arranged on before being integrated into electric spray gun in the control device, and this is still feasible at present, but normally not all right.At present, usually low dc voltage is applied on the electric spray gun by primary cable from control device, and converts 4000V-14000V or higher dc high voltage to by the high pressure generator that is arranged in the electric spray gun.
The sprayed on material amount that high-voltage value, the high-tension current that flows through electrode and/or unit interval carry and/or for example in order to spray sprayed on material or to form the minor alteration of the pressure air amount that unit interval of sprayed on material spray bundle carries and/or the change of air pressure may cause the decline of coating quality.Therefore, need operating personnel constantly to observe the spray bundle of ejection and the object that will spray.In above-mentioned prior art, can provide voltage to show to operating personnel, promptly, after connecting high voltage, the button that operating personnel press electric spray gun at first starts spraying, in case high voltage does not exist or drops to specified minimum value, operating personnel are interrupted spraying immediately by the button that unclamps electric spray gun.If the voltage display in the light emitting diode position has a voltmeter, operating personnel just can see actual at that time magnitude of voltage.
Yet, advantageously operating personnel can obtain the information of other spraying operation, for example high voltage-electrode current-rated value, high voltage-electrode current-actual value, maximum allow high voltage-limiting value, the constant maintenance high voltage of operator scheme and/or the constant maintenance high voltage-electrode current of operator scheme, the object that operating personnel's head needn't turn to the spray bundle and will spray, for example turn to the object that will spray, on control device, can regulate operating parameter and control device and have the display that shows described information usually from control device.
With the firm shortcoming that is connected the display that maybe will take a long time to separate its connection of injection apparatus be, injection apparatus need be used cleaning agent such as solvent clean, and display can not bear the effect of cleaning agent or solvent.Another shortcoming is, when display goes wrong, and the expense height of exchange device more, or must the whole injection apparatus of replacement because display is non-dismountable with being connected of injection apparatus.Also have a shortcoming to be, when the dorsal part of spraying object or cavity were sprayed, injection apparatus must or move into the object the inside near object, and under these circumstances, sprayed on material will contact display.In this case, advantageously, display is not arranged on the injection apparatus, and be arranged with the injection apparatus branch, but be arranged on the zone that operating personnel can see display, operating personnel needn't change or not change substantially forward towards the cephalad direction of spray bundle or spraying object like this, thereby both can see spray bundle and spraying object, viewing area that again can observation display.For example, in this case advantageously, display is arranged on a spraying object or the supporting member, and this supporting member is arranged on the back of spraying object or is directly adjacent to the setting of spraying object.
Summary of the invention
The objective of the invention is to, overcome above-mentioned shortcoming and obtain above-mentioned advantage, particularly form such spraying equipment, promptly, the locus of injection apparatus, operation possibility, cleaning possibility and service life and display are irrelevant, and the part of display is also irrelevant and be positioned at the position that operating personnel can see its viewing area thus with control device, operating personnel directly facial or tiltedly facing to the spray bundle or be in spraying object in the spray bundle.
Purpose of the present invention is realized by the feature of claim 1.
To this, the objective of the invention is to realize by such spraying equipment, promptly, it comprises that a control device and at least one are used for the optical display that optics shows the spraying operation information of at least a spraying operation information and receiving control device, by control device electric energy is transported to the electrojet device through electric lead, the formation of this injection apparatus makes sprayed on material spray on the object that will spray and has a high-voltage electrode at least, be used for sprayed on material being carried out electrostatic charging by high voltage, wherein control device is constituted as and regulates at least a spraying operating parameter, it is characterized in that, control device is constituted as the transmitter of at least a demonstration spraying of wireless transmission operation information data, and display is constituted as the receiver of at least a spraying operation information of wireless receiving data.
Thus, can produce following advantage: injection apparatus, display and control device can irrespectively locate each other, use and clean.Its display can be arranged on the optional position of neither being made dirty and not influencing injection apparatus or control device use.When injection apparatus or control device go wrong, do not need to change or the dismounting display, and when display goes wrong, do not need to change or dismounting injection apparatus or control device.Can adopt cheap acknowledgment copy thus.Wireless transmission data are with respect to wired as be by the advantage that lead transmits data, the distance between can each parts of regulated at will, and do not need the lead of different length; The mobility of each positioning parts is bigger, can also be used in the occasion that can not use lead; The data transmission wires that does not have necessary cleaning; Cost saving.
Dependent claims has comprised other embodiment of the present invention.
