本発明は塗装ラインに沿つて搬送される被塗物
に向けて静電塗装を行なう静電塗装装置の改良に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an electrostatic coating device that performs electrostatic coating on objects to be coated that are transported along a coating line.
一般に、静電塗装装置は塗装機に例えば−
90KVの高電圧を印加し、アース電位にある被塗

ながら塗装を行なうようにしている。 Generally, electrostatic coating equipment is applied to a coating machine, e.g.
A high voltage of 90KV is applied, and the electrostatic atomized paint is made to fly along the lines of electric force using the potential difference between the material and the object at ground potential, and is applied to the object. Painting is done by. The coating machine is supported by a reciprocator, and the coating is performed while moving the coating machine vertically and back and forth while the object to be coated is suspended and conveyed from a conveyor provided in the coating line.
ところで、前述のような静電塗装を行なうには
塗装機と被塗物との間の離間距離即ち塗装距離を
一定（例えば300mm程度）に保たなければならな
い。即ち、塗装機には前述のような高電圧が印加

より高電圧を高速遮断するように構成されてい
る。 By the way, in order to perform electrostatic painting as described above, the separation distance between the coating machine and the object to be coated, that is, the coating distance, must be kept constant (for example, about 300 mm). In other words, since the above-mentioned high voltage is applied to the paint sprayer, if the paint sprayer gets too close to the object to be coated (e.g. less than 200mm), spark discharge will occur and the thinner, solvent, etc. will ignite. This is extremely dangerous as it may cause a fire. For this reason, the high voltage generator is equipped with a high voltage cutoff device, and is configured to cut off the high voltage at high speed when the coating machine approaches the object to be coated abnormally.
従来、かかる高電圧遮断装置としては、塗装機
と被塗物との間に流れる微小電流を検知し、この
電流値の変化に応じて高電圧を遮断する構成のも
のが知られていた。 Conventionally, such a high voltage cutoff device has been known to detect a minute current flowing between a coating machine and an object to be coated, and cut off the high voltage according to a change in the current value.

作動しないことがあつた。 However, when the object to be coated rapidly approaches the coating machine, for example when the object to be coated is swinging and suspended from a conveyor, the high voltage interrupting device in the prior art as described above cannot be used. Abnormal approach may not be detected. Further, even if the distance between the object to be coated and the coating machine is constant, the current flowing between the objects to be coated is significantly different between needle-shaped objects and flat objects. For this reason, the high voltage cut-off device may malfunction and cut off the high voltage even though the object to be coated is not abnormally close, or conversely, it may not operate even if the object to be coated is abnormally close to the paint sprayer. It was hot.

る。 The present invention has been made in view of the above points, and is an optical system consisting of a light emitter and a light receiver arranged vertically opposite each other so as to sandwich the object to be coated in front of the reciprocator in the middle of the painting line. Using a sensor, the shape of the object to be coated on a horizontal plane is recognized in advance before the object reaches the atomizer, and if the object to be coated is recognized in this way and approaches the atomizer, it can be detected in advance. If there is a possibility that the separation distance will be less than the set distance, the conventional high-voltage cutoff device (which operates by detecting the minute current flowing between the paint sprayer and the object to be coated) will be activated. The first object of the present invention is to provide an electrostatic coating device that can cut off high voltage in advance.

The present invention is characterized by comprising a high voltage cutoff device that cuts off the high voltage from the high voltage generator before the object to be coated reaches the coating machine if there is a possibility that the voltage falls below a set value. .

If the amplitude of the object 1 to be coated in the left-right direction is too fast or too large, the coating machine 10 may not be able to be moved backward in accordance with the amplitude.
However, since the amplitude of the object 1 to be coated is recognized by the optical sensor consisting of the light emitter 6 and the light receiver 7 described above, the amplitude may be such that the object 1 to be coated may abnormally approach the coating machine 10. However, if the coating distance is less than the predetermined painting distance, the high voltage interrupting device 1 is activated via the high voltage generating device 12 in response to a interrupting signal from the computing device 8 before the object 1 to be coated reaches the coating position.

Even if it is, the value of the current flowing between them will be large. However, since the optical sensor consisting of the light emitters 4 and 6 and the light receivers 5 and 7 can also distinguish between the needle-shaped portion 1A and the flat plate-like portions 1B and 1C of the workpiece 1, it is possible to distinguish between the shape of the workpiece 1. By driving the reciprocator 9 according to the change, the sprayer 10 can always be placed at the optimum coating position. Therefore, malfunction of the high voltage interrupting device 11 is prevented.

An optical sensor consisting of a container and a light receiver recognizes the planar shape of the object to be coated on a horizontal plane, and the coating machine approaches the object abnormally due to the planar shape of the object to be coated recognized by the optical sensor. If there is a possibility that the separation distance is less than a preset distance, the high voltage cut-off device is activated before the object reaches the sprayer, so the object is transported to the conveyor. Even if the coating machine and the object to be coated suddenly come abnormally close to each other due to oscillation or the like during the spraying process, the high-voltage cutoff device can be activated in advance. In addition, instead of estimating the distance between the coating machine and the object to be coated by indirect means such as changes in current value, the planar shape is directly recognized, which prevents malfunctions of high-voltage cut-off devices. It has various effects such as reliable prevention.
