Description

  The present invention relates to a painting work training apparatus, and more particularly, to a painting work training apparatus for learning painting work such as bumper painting.

  In general, when painting a bumper or the like, a training for familiarizing the painting work is performed before the worker officially performs the painting work on the production line.

  Conventionally, this kind of painting work training is performed as shown in FIG. First, a trajectory 200 of movement of a coating machine (not shown) is drawn in advance on an object surface 100 such as a bumper, and a tip of a coating hand gun (not shown) is not shown. A rod (not shown) having the same length as the distance between the coating material and the coating machine is attached.

  Thus, the worker moves the object along the trajectory 200 while sliding the tip of the rod body perpendicularly to the object surface 100 such as a bumper while sliding on the object surface 100. Proficiency takes place.

  However, in such painting work training such as bumper painting without actually spraying paint, although the operator can learn how to move the painting handgun along the movement locus 200, there are the following difficulties. .

  First, it is only necessary to learn how to move the paint hand gun, and it is impossible to learn the paint pattern width (paint width).

  Secondly, according to such painting work training, it can be easily performed when the object to be coated is a flat surface such as a bumper. Since it is also necessary to carry out plate coating, training to get paint into a hidden place such as the door inner plate surface is impossible.

  Thirdly, in such a painting work training, since the paint is not actually used, the locus of the sprayed paint cannot be seen, and the operator cannot learn the realistic feeling of the paint work.

  It should be noted that there is no prior art document information to be described for such a bumper painting work training apparatus.

  On the other hand, as another painting technique, a teaching device for painting with a painting robot equipped with a multi-axis robot arm for attaching a coating machine to the tip is known (for example, see Patent Documents 1 and 2). Since the device focuses on teaching robots, numerical information can be obtained, but the operator cannot directly understand the painting work, and the painting work is performed in parallel while understanding the painting work. There was a difficulty that I could not do.

  For this reason, the present applicant, as shown in FIG. 10, previously, the handgun body 300, a plurality of laser-introducing optical fiber cables 400a, 400b, 400c disposed in the handgun body 300, and each laser introduction A painting work training apparatus provided with probes 500a, 500b, and 500c provided at the distal ends of the optical fiber cables 400a, 400b, and 400c and spaced apart from the distal ends of the handgun body 300 has been devised and applied. (Japanese Patent Application No. 2009-056887). In the figure, reference numeral 600 indicates a trigger.

  Such a painting work training apparatus has the following effects.

  First, instead of the paint, laser light can be emitted from the tip of the probes 500a, 500b, and 500c, so that it can be used even in an environment without a local exhaust device (local exhaust) or air conditioning.

  Second, since the laser light is guided by the laser-introduced optical fiber cables 400a, 400b, and 400c, the laser light can be used even if the implementation location is designated as explosion-proof.

  Third, since the paint can enter the concealed area by checking whether or not the laser beam enters, it can be confirmed in advance even if the paint surface is likely to be shaded, such as the door plate. it can.

  Fourth, in the case where a nozzle for spraying water is provided at the tip of the handgun body 300, when water is sprayed from the nozzle and laser light is irradiated, the light trajectory is visually observed due to light scattering by the water spray. It is also possible to obtain an actual feeling of painting.

  Fifth, in the case of emitting a belt-like or elliptical laser beam from each of the probes 500a, 500b, and 500c, the laser beam applied to the object to be coated is adjusted so as to be positioned on the same line. It is possible to confirm the pattern width, the coating layer, the distance between the hand gun and the object to be coated, and the inclination of the hand gun.

  However, the painting work training apparatus having such a configuration has a drawback that it cannot learn the moving speed of the handgun.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the best embodiment to which a painting work training apparatus of the present invention is applied will be described with reference to the drawings.

  FIG. 1 is a schematic diagram showing an example of a painting work training apparatus in an embodiment of the present invention.

  In FIG. 1A, a painting work training apparatus 1 according to the present invention includes a tube 2 arranged along a predetermined locus, for example, a locus on the object to be coated such as a bumper, and a position separated from the tube 2, for example, A hand gun 3 disposed on the coating machine side, a light emitter 4 is movably accommodated in the tube 2, and a light receiver 5 for receiving light from the light emitter 4 is disposed in the hand gun 3. ing.

  As shown in FIG. 1B, the tube 2 is made of a plastic tube typified by a nylon (registered trademark) tube or a soft fluororesin tube that is transparent or translucent in the visible light region. The inner diameter of the tube 2 is set to a dimension sufficient for disposing the light emitter 4 described later so as to be movable in the tube 2, for example, about 40 to 42 mm. The wall thickness of the tube 2 is appropriately determined depending on the relationship between the material of the tube 2 and the processing.

  The tube 2 having such a configuration is filled with a fluid 6 made of water or the like. Thereby, the moving speed of the light emitter 4 can be controlled by automatically controlling the flow rate of the pump 7 (see FIG. 2) described later.

  As shown in FIG. 2A, a pump 7 for supplying fluid 6 into the tube 2 or sucking the fluid 6 in the tube 2 is connected to one end of the tube 2 in a liquid-tight manner. A back 8 that slides and expands in response to the supply and suction of the fluid 6 is liquid-tightly connected to the section.

  The pump 7 is provided with a cylinder 71 made of, for example, a ROBO cylinder, and the cylinder 71 moves (slides) in the axial direction by rotating the cylinder 71. That is, the rotation is used as the cylinder movement amount to ensure quantitativeness. can do. Thereby, pulsation does not arise in the movement of the fluid 6, and hence the movement of the luminous body 4, and the speed control with excellent quantitativeness can be performed.

  Further, as shown in FIG. 2B, a first strainer 10a is provided in the vicinity of the pump 7 in the tube 2, and in the vicinity of the back 8 side in the tube 2 as shown in FIG. As shown, a second strainer 10b is provided. By disposing such first and second strainers 10 a and 10 b in the tube 2, it is possible to prevent the luminous body 4 from flowing into the pump 7 or the back 8.

  FIG. 3 shows a cross-sectional view of the light emitter 4.

  In the figure, the light emitter 4 is transparent or semi-transparent to the visible light region and has a spherical case 41 having a diameter of about 40 mm, a light emitting unit 42 accommodated in the case 41, and a case 41. It is provided with a filling member 43 filled therein, and presents a spherical LED ground (electric ground) as a whole.

  The case 41 is formed of an inexpensive material such as acrylic resin or polyethylene terephthalate (PET) resin when water is used as the fluid.

  The light emitting unit 42 includes an LED 42a as a light emitting member, a battery 42b for supplying power to the LED 42a, and a switch 42c provided as necessary. The battery 42b and the switch 42c are connected to the LED 42a via a lead wire 42d. It is connected to the. Here, the luminous intensity of the LED 42a is adjusted including the amplifier on the light receiver 5 side, and by such adjustment, it is possible to reduce the influence of disturbance such as illumination in the training workplace.

  The filling member 43 is filled to make the luminous body 4 have the same specific gravity as the surrounding fluid (liquid such as water), and is made of liquid, resin, or the like. As the liquid or resin, it is necessary to use a liquid that is transparent so as not to be shielded from light, or that is electrically insulative with respect to the LED 42a or the battery 42b. It is preferable to take the balun so that it is located on the surface side.

  The light emitter 4 having such a configuration is disposed in the tube 2 so as to be movable with the movement of the fluid 6 such as water. Moreover, since the light-emitting body 4 is smoothly moved in the fluid 6 such as water, it is preferable to adjust the weight so as not to cause sedimentation or levitation. The weight of the light emitter 4 is preferably about 33 to 34 g as a whole when the light emitter 4 has a diameter of about 40 mm and water is used as a fluid.

  The tube 2 in which the light emitting body 4 is movably accommodated is wound along a locus 91 on the surface of an object 9 such as a bumper as shown in FIG. In addition, the said tube 2 is being fixed to the to-be-coated object 9 grade | etc., With the bind line (not shown).

  As shown in FIG. 5, the tube 2 is arranged in a single stroke state. In addition, it is preferable that the U-shaped tube 21 is liquid-tightly connected to a portion corresponding to the bent portion of the trajectory 91 in the one-stroke-written tube 2.

  As shown in FIG. 6, the hand gun 3 includes a hand gun body 31 having a width dimension H of about 40 mm, a grip 32 projecting downward on the lower surface near the rear end of the hand gun body 31, A trigger 33 pivotally supported by the handgun body 31 at a partial position and a light receiver 5 disposed in the handgun body 31 are provided.

  The light receiver 5 is disposed concentrically with the axis of the hand gun body 31 on the front side of the light receiver body 51 (the side facing the light emitter 4), which receives light from the light emitter 4. The cylindrical body 51 is provided. The light receiver 5 is set so that when a specific wavelength is received with a specific intensity or more for noise removal, it is regarded as a proper light receiving state. Specifically, the light receiver main body 51 detects only when light of a certain intensity or higher that detects light (red) of about 610 to 660 nm (peak value 635 nm) reaches the light receiver main body 51. Is set to Thereby, the influence by noise, such as illumination in a training field, can be suppressed.

  As the cylindrical body, as shown in FIG. 7, a cylindrical body 52 having an outer diameter of about 10 mm and an axial length of about 100 mm is used, and a black paint 52 a is formed on the inner surface of the cylindrical body 52. It is painted. Here, the reason why the cylindrical body 52 having a predetermined length is disposed at the front position (the side facing the light emitter 4) of the light receiver main body 51 is to prevent light from being received from a direction other than a specific direction. Specifically, the light when the handgun 3 is not directed to the front with respect to the light emitter 4, that is, where light is emitted from various directions in the training field, the axis of the light receiver body 51, This is to prevent the incidence of light that does not coincide with the light in the direction orthogonal to the surface of the object to be coated among the light emitted from the light emitter 4 and the axis of the cylindrical body 52. The reason why the black paint is applied to the inner surface of the cylindrical body 52 is to prevent light incident as noise from being reflected in the cylindrical body when the handgun 3 is not directed to the front side with respect to the light emitting body 4. is there.

  Next, operation | movement of the painting work training apparatus 1 comprised in this way is demonstrated.

  In FIG. 8, first, the fluid 6 is sucked at the time of preparation, and it is preferable to deaerate since mixing of bubbles becomes a problem in actual use. Specifically, the pressure in the tube 2 is lowered by forcibly sliding the back 8, whereby most of the gas dissolved in the fluid 6 such as water can be removed.

  Next, when the fluid 6 is supplied from the pump 7 during training, the fluid 6 in the tube 2 moves toward the back 8 side, and the light emitter 4 also moves as the fluid 6 moves.

  On the other hand, the trainer arranges the tip of the hand gun 3, that is, the portion facing the light emitter 4 of the hand gun body 31 to face the light emitter 4 in the tube 2, and then trigger 33 of the hand gun 3. pull. Thereby, the switch of the light receiver 5 is turned on, and a timer (not shown) built in the hand gun 3 is activated.

  Then, the trainee moves the light gun 4 in accordance with the movement of the light emitter 4 with the tip of the hand gun 3 facing the front, and releases the trigger 33 of the hand gun 3 when the light emitter 4 stops. Thereby, the switch of the light receiver 5 is turned off, and the distance that the trainee has moved the handgun 3 along the locus, that is, the length of the locus that is moved in accordance with the movement of the light emitter 4 (the length of the tube 2). ) And the accumulated time of the timer, the movement speed of the handgun in the trainee can be obtained.

  Here, in the present invention, the state in which the trigger 33 of the handgun 3 is pulled is the operating state of the handgun 3, and when the trainee is in the state in which the tip of the handgun 3 is directed to the front, that is, the handgun 3 Since the light from the light emitter 4 is set to be received when the light emitter 4 is on the axis of the cylindrical body 52, the light receiver body 51 receives the light from the light emitter 4. The handgun 3 can be regarded as synchronized with the movement of the light emitter 4. In this case, when the light receiver main body 51 is not receiving light from the light emitter 4, that is, when the tip of the hand gun 3 is not facing the front of the hand gun 3 (the axis of the cylindrical body 52 of the hand gun 3). Informing means, for example a relay, that operates when the light emitter 4 is not on the line) or when the handgun 3 does not match the moving speed of the light emitter 4 (when the handgun 3 is slower or faster than the moving speed of the light emitter 4). If a means for turning the patrol light on and off (lighting and blinking of the patrol light) is provided in the circuit using the, it can be determined that the movement of the handgun 3 deviates from the ideal speed. Thus, the trainee determines that the tip of the handgun 3 is in a state of being directed to the front if the notification means does not operate (for example, if the patrol light is not turned on), and the speed at which the handgun 3 is ideal It can be moved with. Note that the ideal speed of the handgun 3 is approximately the same speed as the predetermined speed (about 450 to 500 mm / sec). The speed of the hand gun 3 is set so as not to cause unevenness in work efficiency due to manual work (when a single object is painted, the speed increases and decreases, and the speed is different for each unit). From this viewpoint, it is set to about 450 to 500 mm / sec.

  As described above, according to the painting work training apparatus 1 of the present invention, the moving speed of the luminous body 4 in the tube 2 is matched with a predetermined speed (about 450 to 500 mm / sec), and the trainee can The moving speed of the handgun 3 can be learned by moving the handgun 3 according to the moving speed.

  The present invention has been described with respect to the present invention with specific embodiments shown in the drawings. However, the present invention is not limited to these embodiments, and as long as the effects of the present invention are exhibited. Any configuration known so far can be employed.

  For example, although water is used as the fluid 6 in the above-described embodiment, a fluid liquid such as a volatile solvent such as an organic solvent or alcohol may be used. However, when an organic solvent is used as the fluid 6, it is preferable to select a solvent that does not require an explosion-proof treatment. In the case of a liquid that dissolves a resin such as acetone or ethyl acetate, or a strong acid or strong alkaline solvent, There are many restrictions on the material of the case and the tube constituting the light emitting part, and when a volatile solvent such as alcohol is used as the fluid 6, the volume of the fluid may change when the tube is not tightly sealed. It is necessary to be careful not to cause vaporization and burst in the summer.

  In the above-described embodiment, a cylindrical body is used. However, a trumpet-shaped cylinder, a hexagonal cylinder, a square cylinder, or the like whose diameter is reduced from the front end portion toward the rear end side may be used.

  Further, in the above-described embodiment, when the tip of the hand gun 3 is not facing the front, the patrol light as the notifying means is turned on. However, when the tip of the hand gun 3 is facing the front, the notifying means The patrol light may be turned on or blinked.
