  As a method of suppressing the generation of the remaining cleaning part, a method of adjusting the cleaning nozzle for the cleaning part in the actual cleaning state can be considered, but after the cleaning liquid sprayed from the nozzle hits the object to be cleaned, it bounces off and scatters. Since it became mist-like, it was difficult to confirm the cleaning part, and the orientation of the nozzle could not be adjusted accurately. Therefore, when adjusting the position of the cleaning nozzle, a method of reducing the cleaning pressure so that the target position can be confirmed can be considered, but when adjusting the nozzle with a low pressure, for example, the target position is farther from the nozzle. Since it is greatly affected by gravity, the target position of the nozzle is deviated from the actual cleaning pressure. Therefore, in order to eliminate the deviation, there is a drawback that the position of the nozzle must be adjusted while correcting by visual measurement.

  In addition, the invention of the above-mentioned patent document 1 can adjust the interval of the nozzles to the position where the object to be cleaned is arranged by simply aligning the nozzles with the scales displayed in advance according to the type of the object to be cleaned. Although possible, the position of the nozzle in the actual cleaning state could not be adjusted to the cleaning site. Moreover, although the invention of the said patent document 2 was able to wash | clean the coating gun penetrated to the upper hole of the washing | cleaning case with the washing | cleaning liquid from the washing nozzle supported by the arm, In the actual cleaning state, the position of the cleaning nozzle could not be adjusted to the cleaning site. Further, the invention of the above-mentioned Patent Document 3 was able to clean the coating gun entering from the opening of the cleaning tank by spraying a solvent from a plurality of cleaning guns arranged so as to surround, As in Patent Document 1, the position of the cleaning gun could not be adjusted to the cleaning site in the actual cleaning state.

  Therefore, the present invention has been made in view of such circumstances, and aims at the nozzle of a cleaning machine capable of accurately adjusting the position of the cleaning nozzle with respect to the cleaning portion while maintaining the pressure of the cleaning liquid in the actual cleaning state. An object of the present invention is to provide a position adjusting device and a method thereof.

  In order to solve the above-described problems, a nozzle aiming position adjusting apparatus and method for a washing machine according to the present invention is characterized by having the following configurations.

(Aspect of the Invention)
As with the claims, each aspect is divided into sections, each section is numbered, and is described in a form that cites the numbers of other sections as necessary. This is for the purpose of facilitating the understanding of the technology described in this specification, and is intended to limit the technical features described in this specification and combinations thereof to those described in the following sections. Absent. In other words, the technical features should be interpreted in consideration of the description accompanying each section, the description of examples, etc., and as long as the interpretation is followed, another aspect is added to the form of each section. Moreover, the aspect which deleted the component from the aspect of each term can also become one aspect. In the following items, each of items (1) to (2) corresponds to each of claims 1 to 2.

(1) In a nozzle aiming position adjusting device of a cleaning machine having a numerically controlled cleaning nozzle and causing the cleaning liquid sprayed from the cleaning nozzle to reach the cleaning site of the object to be cleaned,
A pedestal portion attached to the object to be cleaned;
A cylindrical portion erected on the pedestal,
A cone-shaped portion disposed on the pedestal in the cylindrical-shaped portion so that a tip portion thereof coincides with a central axis of the cylindrical-shaped portion;
A nozzle aiming position adjusting target comprising a plurality of cleaning liquid discharge holes formed at equal intervals in the circumferential direction on the bottom side wall of the cylindrical portion,
A nozzle aiming position adjusting device for a washing machine, wherein a tip of the conical portion of the nozzle aiming position adjusting target is disposed so as to face the washing nozzle.

  The cleaning nozzle of this cleaning machine can perform three-dimensional operation in the X-axis direction, the Y-axis direction, and the Z-axis direction by numerical control (NC: Numerical Control), and in the vertical and horizontal directions around the swivel axis The direction of can be changed. The cleaning nozzle can be moved to a plurality of arbitrary positions by the NC.

  The nozzle aiming position adjustment device of this cleaning machine is equipped with the cleaning nozzle height, direction, etc., for the cleaning liquid sprayed from the cleaning nozzle to accurately reach the cleaning part of the object to be cleaned. Nozzle aiming position adjustment target (hereinafter simply referred to as an adjustment target) is provided. The adjustment target is roughly composed of a pedestal portion, a cylindrical portion, and a conical portion, and is used by being attached to an object to be cleaned when adjusting the position of the cleaning nozzle. The pedestal portion is provided on the bottom of the adjustment target, and the pedestal portion is fixed on the object to be cleaned by attachment means (for example, a chuck hand, a hinge provided on the jig, etc.). The cylindrical portion is erected in the vertical direction with respect to the upper surface of the pedestal portion, and has a hollow cylindrical shape. The cone-shaped portion is erected on the pedestal portion in the same manner as the cylinder, with its tip end aligned with the central axis of the cylinder. The sizes of the diameters of the cylinder and the cone-shaped part are respectively determined so that a space is formed between the outer periphery of the cone-shaped part and the inner periphery of the cylinder.

  A hole penetrating the side wall is formed on the side wall of the cylinder at the same height and at a position dividing the circumferential direction at equal intervals. The holes are holes (cleaning liquid discharge holes) for discharging the cleaning liquid sprayed from the cleaning nozzle to the outside of the cylinder, and a plurality of, for example, four, are provided at positions close to the pedestal, that is, at low positions below the side walls. 12 pieces are formed.

  The adjustment target is disposed so that the upper side of the cylinder in the open state and the tip of the conical portion face the cleaning nozzle. The diameter of the cleaning nozzle is smaller than the inner diameter of the cylinder, and the cleaning liquid ejected from the cleaning nozzle is sprayed to the opening of the cylinder and hits the cone-shaped part in the cylinder, and then along the slope of the cone-shaped part. Or is scattered and proceeds along the inner peripheral surface of the cylinder, and is discharged from the cleaning liquid discharge hole to the outside of the cylinder. Since the cleaning liquid discharge hole is formed at a symmetrical position on the cylindrical side wall, for example, when the cleaning pressure is so large that the progress of the cleaning liquid can ignore the influence of gravity, the cleaning liquid sprayed from the cleaning nozzle has a conical shape. The cleaning liquid is evenly discharged from the cleaning liquid discharge holes when it hits the tip of the conical portion in the same direction as the axis of the part.

  In addition, the shape of the part which a washing | cleaning liquid touches is not limited to a cone-shaped part, For example, polygonal pyramid shapes, such as a regular triangular pyramid and a regular quadrangular pyramid, may be sufficient. Even in these shapes, if the cleaning liquid from the cleaning nozzle is sprayed from the direction perpendicular to the axis of the tip, the cleaning liquid is evenly distributed on the outer periphery of the cone and is uniformly discharged from each cleaning liquid discharge hole. . In the case of a polygonal pyramid shape, the number of cleaning liquid discharge holes formed on the side wall is the same as the number of corners of the cone.

(2) A nozzle aiming position adjusting method for a washing machine, wherein the nozzle aiming position is adjusted using the nozzle aiming position adjusting device for the washing machine according to item 1,
Adjusting and adjusting the fixed position of the cleaning nozzle and the central axis of the adjustment target on one axis on which the cleaning nozzle moves by numerical control;
The cleaning pressure of the cleaning liquid sprayed from the cleaning nozzle is adjusted to the same pressure as the cleaning pressure in the actual cleaning state,
A nozzle aiming position adjusting method for a cleaning machine, wherein the position of the cleaning nozzle is adjusted so that the cleaning liquid sprayed from the cleaning nozzle and hitting the conical portion is uniformly discharged from the plurality of cleaning liquid discharge holes. .

  This adjustment method is used in the correction adjustment work of the mounting position of the cleaning nozzle. The adjustment target is fixed to the object to be cleaned through the attaching means. The washing nozzle can be moved three-dimensionally by the NC, and the direction of the washing nozzle can be changed around the pivot axis. First, the cleaning nozzle and the adjustment target attached to the object to be cleaned are arranged facing each other, and the cleaning nozzle and the adjustment target are arranged on one of the axes on which the cleaning nozzle moves by numerical control. At this time, the cleaning nozzle places the fixing position of the cleaning nozzle attached to the numerical controller on the axis, and the adjustment target arranges the central axis on the axis. Next, in order to make the direction (axial direction) of the cleaning nozzle coincide with the central axis of the conical portion, the cleaning liquid is sprayed from the cleaning nozzle toward the adjustment target. The pressure of the cleaning liquid sprayed at this time is set to the same pressure as the cleaning pressure in the actual cleaning state.

The sprayed cleaning liquid hits the cone-shaped portion, and then travels along the inclined surface of the cone-shaped portion or scatters along the inner circumferential surface of the cylinder, and is discharged from the cleaning liquid discharge hole to the outside of the cylinder. The cleaning nozzle is moved and adjusted in the X, Y, and Z axis directions or about the pivot axis until the cleaning liquid is uniformly discharged from each cleaning liquid discharge hole. Since the cleaning liquid discharge holes are formed at equal intervals along the outer periphery of the cylindrical side wall, the adjustment position where the cleaning liquid is uniformly discharged from each cleaning liquid discharge hole is the target position of the cleaning nozzle. The coordinates of the target position of the cleaning nozzle adjusted in this way become the origin of the cleaning target, and the cleaning nozzle can be accurately moved to each cleaning site of the object to be cleaned by numerical control. At this time, the cleaning site that is the origin of the object to be cleaned is the intersection of the center axis of the adjustment target and the object to be cleaned, that is, the position vertically lowered from the tip of the conical portion with respect to the object to be cleaned. .
By such a method, the target position of the cleaning nozzle in the actual cleaning state can be adjusted while visually observing the amount and momentum of the cleaning liquid discharged from the plurality of holes formed in the adjustment target. The target position can be adjusted.

  According to the nozzle aiming position adjusting apparatus and method of a cleaning machine according to the present invention, the cleaning pressure of the cleaning liquid sprayed from the cleaning nozzle is kept at the actual cleaning pressure, that is, in the same state as the actual cleaning state. Since the target position can be adjusted, the nozzle can be accurately adjusted to the target position without deviation, and the dirt on the object to be cleaned can be reliably cleaned. In addition, the target position of the cleaning nozzle can be adjusted while visually confirming the amount and momentum of the cleaning liquid discharged from the holes formed at equal intervals, so that the nozzle can be accurately and easily adjusted to the target position, and the cover can be reliably covered. The dirt of the washing object can be washed.

FIG. 5 is a partial cross-sectional view (a) and a front view (b) showing an embodiment of a nozzle aiming position adjusting device different from FIG. 4.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Note that the present invention is not limited to the following embodiments, and includes various embodiments based on the knowledge of those skilled in the art, including the embodiments described in the above section (Aspects of the Invention). It can be carried out in a modified or improved manner.

This apparatus and its method are used for a washing machine that can wash an object to be washed by moving a washing nozzle to a plurality of arbitrary positions using an NC control device.
As shown in FIG. 1, a nozzle aiming position adjusting device 1 of a cleaning machine is composed of a nozzle part 2 and a nozzle aiming position adjusting target part (hereinafter referred to as an adjusting target) 3.
The nozzle unit 2 is controlled by a numerical control device (not shown) and includes a nozzle body 4 and a cleaning nozzle 5 and can perform three-dimensional operations in the X-axis, Y-axis, and Z-axis directions. The direction in the left-right direction can be changed around (in this case, coincides with the Z-axis). The X-axis direction is the front-rear direction of the cleaning nozzle 5 relative to the adjustment target 3, the Y-axis direction is the left-right direction of the cleaning nozzle 5 relative to the adjustment target 3, and the Z-axis direction is the vertical direction of the cleaning nozzle 5 relative to the adjustment target 3. Further, the Z axis is set as a turning axis of the cleaning nozzle 5. The position of the cleaning nozzle 5 is controlled so that the sprayed cleaning liquid W reaches the adjustment target 3.

  As shown in FIGS. 1 and 2, the adjustment target 3 includes a pedestal portion 6 provided at the bottom thereof, a cylindrical portion 7 erected on the pedestal portion 6 in a direction perpendicular to the upper surface thereof, and a cylinder. 7 and a cone-shaped portion 8 erected in 7. The adjustment target 3 is attached to an object to be cleaned when the target position of the cleaning nozzle 5 is adjusted. The pedestal portion 6 has a plate shape (for example, a disc shape), and mounting holes 9a and 9b are provided in the periphery thereof, and the adjustment target 3 is mounted via the mounting holes 9a and 9b. It is attached and fixed on the cleaning portion of the object to be cleaned by means (for example, a chuck hand, a hinge provided on the jig, a screw, etc.).

  The cylindrical portion 7 has a hollow cylindrical shape, and the side wall of the cylindrical portion (hereinafter referred to as a cylinder) 7 has the same height in the height direction of the cylinder and has holes at equal intervals in the circumferential direction. 10 is formed through the side wall. The hole 10 is a cleaning liquid discharge hole 10 for discharging the cleaning liquid W sprayed from the cleaning nozzle 5 to the outside of the cylinder, and is formed in a lower lower part (position close to the base part 6) in the height direction of the cylinder. . For example, the number of the cleaning liquid discharge holes 10 is set to any number from 4 to 12.

  The cone-shaped portion 8 is erected on the pedestal portion 6 at the center in the cylinder 7 so that the central axis of the cylinder 7 coincides with the central axis. That is, the tip portion 11 of the conical portion is provided on the central axis of the cylinder 7. The conical portion 8 is fixedly attached to the pedestal portion 6 by fixing means 13 (for example, screws) (see FIG. 2). Further, the size of the bottom of the cone-shaped portion 8 is set such that a space portion 12 (see FIG. 2) exists between the outer periphery of the cone-shaped portion 8 and the inner periphery of the cylinder 7.

  The adjustment target 3 determines the mounting and fixing position of the cleaning nozzle 5 such as the height and direction of the cleaning nozzle 5 so that the cleaning liquid W sprayed from the cleaning nozzle 5 accurately reaches the cleaning portion of the object to be cleaned. Is to do. As shown in FIG. 1, the adjustment target 3 is arranged with the upper portion of the cylinder 7 (the tip portion of the conical portion 8) facing the cleaning nozzle 5. Although not shown, the adjustment target 3 is attached so that the central axis of the conical portion 8 and the cleaning portion of the object to be cleaned overlap each other when viewed from the cleaning nozzle 5 side. The cleaning liquid W sprayed from the cleaning nozzle 5 hits the cone in the cylinder 7, and then travels along the inclined surface of the cone-shaped portion 8 or scatters along the inner peripheral surface of the cylinder 7 to form on the side wall of the cylinder 7. The discharged cleaning liquid discharge hole 10 is discharged outside the cylinder. Since the central axes of the cylinder 7 and the conical portion 8 coincide with each other and the cleaning liquid discharge holes 10 are formed at equal intervals on the cylindrical side wall, for example, when the cleaning pressure is large and the influence of gravity on the progress of the cleaning liquid is negligible When the cleaning liquid W sprayed from the cleaning nozzle 5 is in the same direction as the axis of the cone-shaped portion 8 and hits the tip end portion 11 of the cone-shaped portion 8 from the same axial direction, The cleaning liquid W to be discharged becomes uniform.

  In FIG. 1, the shape of the portion to which the cleaning liquid is ejected is formed in a conical shape. However, the shape is not limited thereto, and may be a polygonal pyramid shape such as a regular triangular pyramid, a regular quadrangular pyramid, and a regular pentagonal pyramid. In this case, the number of the cleaning liquid discharge holes 10 formed on the outer wall of the cylinder 7 is the same as the number of corners of the cone, and the cleaning liquid discharge holes adjacent to each other on the bottom side of the polygonal pyramid are equally spaced. Formed as follows. Thereby, even if it is a polygonal pyramid shape, the aim position of the cleaning nozzle can be accurately adjusted by equalizing the amount and momentum of the cleaning liquid discharged from each cleaning liquid discharge hole. For example, when the cleaning pressure is large and the influence of gravity on the progress of the cleaning liquid is negligible, the cleaning liquid sprayed from the cleaning nozzle 5 hits the tip of the polygonal cone-shaped portion from the vertical direction so that the cleaning liquid is a polygonal pyramid-shaped portion. The amount and momentum of the cleaning liquid discharged from the cleaning liquid discharge holes are evenly distributed.

Based on FIG. 3, a method for adjusting the target position of the cleaning nozzle used in the correction adjustment operation of the cleaning nozzle mounting position will be described.
The nozzle unit 2 is arranged with respect to the adjustment target 3 attached to the cleaned portion 20 with the front-rear direction as the X-axis, the up-down direction as the Y-axis, the left-right direction as the Z-axis, and the up-down pivot axis as the Z-axis. Set up. The nozzle unit 2 is set to be movable to an arbitrary position by numerical control. The adjustment target 3 is attached and fixed to the object 20 to be cleaned by an attaching means. Adjustment is performed so that the mounting fixing position 35 that is the center of the nozzle portion 2 and the central axis 30 of the adjustment target 3 are arranged on the X axis.

  Next, in order to make the direction of the cleaning nozzle 5 (nozzle axial direction 31) coincide with the central axis 30 of the conical portion 8, the cleaning liquid is sprayed from the cleaning nozzle 5 toward the adjustment target 3. The pressure of the cleaning liquid sprayed at this time is set to the same pressure as the cleaning pressure in the actual cleaning state. After the cleaning liquid hits the conical portion 8, the cleaning liquid travels along the inclined surface or scatters and travels along the inner peripheral surface of the cylinder 7, and is discharged from the cleaning liquid discharge hole 10 to the outside of the cylinder. The position of the nozzle portion 2, that is, the cleaning nozzle 5, so that the cleaning liquid sprayed into the cylinder 7 (the conical portion 8) is uniformly discharged from each cleaning liquid discharge hole 10 formed radially on the side wall of the cylinder 7. Is adjusted in the X, Y, Z axis or in the turning direction. In this case, since the cleaning liquid discharge holes 10 are formed at equal intervals along the outer periphery on the side wall of the cylinder 7, the cleaning liquid sprayed from the cleaning nozzle 5 strikes the tip of the conical portion 8 from the vertical direction. In other words, that is, when the axial direction of the cleaning nozzle 5 (the direction of the cleaning liquid ejected from the nozzle) coincides with the central axis of the conical portion 8, the cleaning liquid is evenly discharged from each cleaning liquid discharge hole 10.

  In the adjustment process of the form shown in FIG. 3, the axial direction 31 of the cleaning nozzle 5 is shifted upward by the angle θ with respect to the central axis 30 of the conical portion 8. Therefore, in this case, the nozzle portion 2 may be adjusted to turn downward by an angle θ about the turning axis (Z axis). If the position at which the cleaning liquid is evenly discharged from the cleaning liquid discharge hole 10 can be specified by such adjustment, the nozzle portion 2 can be moved to any cleaning part by numerical control with the coordinate position as the origin of the cleaning target. it can.

  By this method, the target position of the cleaning nozzle can be adjusted in the same state as the actual cleaning state (the state in which the cleaning pressure is set to the same pressure), so that the cleaning site can be accurately identified without error. Further, since the target position of the cleaning nozzle can be adjusted while observing the amount and momentum of the cleaning liquid discharged from each cleaning liquid discharge hole, the target position can be adjusted easily and accurately.

  FIG. 4 shows another embodiment of the adjustment target. This adjustment target 3 ′ is different from the one shown in FIG. 2 in that the cleaning liquid discharge hole 10 ′ is formed on the bottom surface of the cylinder 7, that is, the pedestal portion 6. The cleaning liquid discharge holes 10 ′ are formed around the conical portion 8 erected so that adjacent cleaning liquid discharge holes penetrate the pedestal portion 6 at equal intervals. The number of the cleaning liquid discharge holes 10 ′ is set to any number from 4 to 12. The cleaning liquid W sprayed from the cleaning nozzle 5 toward the conical portion 8 of the adjustment target 3 ′ travels along the inclined surface of the conical portion 8 or scatters along the inner peripheral surface of the cylinder 7. It passes through the discharge hole and is discharged to the outside on the back side of the adjustment target 3. The central axes of the cylinder 7 and the cone-shaped portion 8 are provided so as to coincide with each other, and the cleaning liquid discharge holes 10 ′ are formed at equal intervals on the bottom surface of the cylinder, so that the cleaning liquid W sprayed from the cleaning nozzle 5 is conical. If the direction is the same as the axis, the cleaning liquid W discharged from each cleaning liquid discharge hole 10 ′ becomes uniform when it hits the tip 11 of the conical portion 8 from the vertical direction. The adjustment target 3 ′ may be attached and fixed to the object to be cleaned via the attachment bracket 40.

  The adjustment target 3 ′ in which the direction of the cleaning liquid discharge hole 10 ′ is the same as the direction in which the cleaning liquid W is incident on the cylinder 7 as in this embodiment has a small cleaning pressure of the cleaning liquid sprayed from the cleaning nozzle 5, and the cylindrical side wall Suitable for use when there is little spread in the direction. By using the adjustment target 3 ′ of the present embodiment, the nozzle aiming position of the cleaning machine can be adjusted easily and accurately. The method for adjusting the target position of the cleaning nozzle 5 and the effect thereof are the same as the adjustment method and the effect of the embodiment shown in FIGS.

  FIG. 5 shows still another embodiment of the adjustment target. This adjustment target 3 ″ does not include a conical member in the cylinder as compared with the configuration shown in FIG. 2, and the cylindrical portion 7 ′ penetrates the pedestal portion 6 to the back of the pedestal portion 6. The flow rate value of the cleaning liquid W that has passed through the cylinder 7 is measured by a flow meter 51 provided at the tip of the cylindrical nozzle, and the target position of the nozzle is adjusted. Since the cleaning liquid W sprayed toward the cylinder 7 of the target 3 ″ flows into the cylinder and reaches the flowmeter 51, the cleaning liquid sprayed from the cleaning nozzle 5 most frequently flows into the cylinder 7. The position is the position of the cleaning nozzle 5 at which the flow rate value of the cleaning liquid measured by the flow meter 51 is maximized, and this position is the target position for the cleaning nozzle. The adjustment target 3 ″ may be attached and fixed to the object to be cleaned via the attachment bracket 50.

  In the case of this embodiment, a flow meter is required, but the structure of the adjustment target 3 ″ can be made simpler than that of the embodiment shown in FIGS. 1 and 4. Also, the adjustment of this embodiment By using the target 3 ″, the nozzle aiming position of the cleaning machine can be adjusted easily and accurately. Note that the target position adjustment method of the cleaning nozzle 5 is the “adjustment step for equalizing the cleaning liquid discharged from each cleaning liquid discharge hole” in the adjustment method of the embodiment shown in FIGS. The adjustment method is replaced with the “adjustment step of maximizing the flow rate value”. The effect is the same as that of the form shown in FIGS.
