(Function) In the cleaning device of the present invention, the cleaning nozzle automatically performs a five-dimensional movement according to a pre-specified command, and the cleaning nozzle automatically performs a five-dimensional movement in accordance with a predetermined command, and targets each article sequentially transferred by the conveying device from a predetermined direction. Completely clean surfaces and holes by spraying a cleaning agent such as cleaning liquid or air.

(Example) The present invention will be described below based on an example shown in the drawings.

In FIG. 1, the cleaning device of the present invention includes a pedestal-like base 2 that is installed to straddle a conveying device 1 such as a belt conveyor. The base 2 includes four legs 3 and four frame members 4 connecting the upper ends of the legs 3.

A plate-shaped first movable base 5 is mounted on the base 2 and is reciprocated in the X-axis direction in a horizontal plane. Both ends 6 and 7 of the first movable base 5 are placed on a pair of opposing frame members 4 of the base 2, and the first movable base 5 extends in the longitudinal direction of the frame members 4. At least one end 6 of the first movable carriage 5 is inserted into a guide groove 8 of the frame member 4, and the other end 7 is inserted into a guide 9 on the other frame member 4 so as to slide along the
is engaged in.

Further, in order to move the first movable table 5 in the X-axis direction, a driving device 10 such as a motor is attached to the base 2. Drive device 10
The first movable base 5 can be moved to the
Move in the axial direction.

Next, on the first movable base 5, Y
A plate-shaped second movable base 12 that is reciprocated in the axial direction (direction perpendicular to the X-axis) is attached.
Similar to the matching of the first movable base 5, this second movable base 12 also has at least one end 13 slidably inserted into the guide groove 14 of the first movable base 5.

Further, a drive device 15 and a screw shaft 16 for reciprocating the second movable base 12 are mounted on the first movable base 5. Drive device 15 and screw shaft 16
has the same structure as the drive device 10 and screw shaft 11.

On the second movable base 12, there is a Z mark perpendicular to the horizontal plane.
A third movable base 17 is attached which is reciprocated in the axial direction. That is, the third movable base 17 is slidably fitted onto a plurality of supports 18 planted on the second movable base 12. A connecting plate 19 is fixed to the upper end of each support column 18 . A screw shaft 21 is installed between the connecting plate 19 and the second movable base 12, and is screwed into the threaded portion 20 of the third movable base 17. By reciprocating the screw shaft 21, the A drive device 22 that reciprocates the third movable base 17 in the vertical direction (Z-axis direction) is attached to the connecting plate 19.

Further, a Z-axis balance cylinder 23 is also provided on the connecting plate 19.

A vertical shaft 24 (R axis) that can reciprocate along the Z-axis direction is attached to the third movable table 17.
A fourth movable base 25 is fixed to the lower end of the shaft so as to rotate together with the fourth movable base 25. The R axis (vertical axis 24) is rotated by a drive device 26, such as a motor, mounted on the second movable table 12 in this embodiment. The drive device 26 is the third movable base 17
It can also be installed on top.

Further, the fourth movable base 25 has a horizontal axis 27 (SW axis) extending in a direction orthogonal to the vertical axis 24.
A fifth movable base 28 is attached which is reciprocated around. A rotation device (not shown) for the fifth movable base 28 is provided within the fourth movable base 25.

The fifth movable base 28 includes the horizontal shaft 27
A desired number of cleaning liquid nozzles 29 and air nozzles 30 that spray cleaning agent in a direction substantially perpendicular to the SW axis.
is installed. Each nozzle 29, 30 has
Hose pipes are connected through communication holes provided in the R and SW axes.

A flexible cover member 31 is provided between the base 2 and the first movable table 5 to cover wiring or piping for transmitting energy such as electric current to the drive device 15. Similar cover members 32 and 33 covering wiring or piping for transmitting the information are provided between the first movable base 5 and the second movable base 12, and between the second movable base 12 and the third movable base, respectively.
It is provided between the movable bases 17.

Further, in order to prevent the cleaning agent from the nozzles 29 and 30 from scattering above the base 2, bellows-shaped covers 34 are stretched between the upper part of the base 2 and the first movable base 5, respectively. Similarly, a bellows-shaped cover 35 is also stretched between the first movable base 5 and the second movable base 12. These covers 34 and 35 are connected to each movable base 5,
Of course, this does not hinder the movement of 12.

Next, the operation of the cleaning device configured as described above will be explained. For example, an object A to be cleaned, such as a cylinder block of an engine that has undergone primary cleaning, is transferred to the vicinity directly below the nozzles 29 and 30 by a conveyance device. When the object is cleaned, each nozzle 29, 30 performs a five-dimensional movement according to a prespecified command such as a computer program, and sprays the cleaning liquid or the like into a predetermined hole or a desired location on a complex surface of the object A to be cleaned. Spray a cleaning agent such as air. In this way, nozzle 2
Since the cleaning agents 9 and 30 perform five-dimensional movement, the cleaning agent can be sprayed from all directions onto the object A to be cleaned in the conveyance device 1, and articles of arbitrary shapes can be completely cleaned.

(Effects of the invention) As explained above, the invention provides the following effects.

a) Since the cleaning nozzles 29 and 30 perform five-dimensional movement, the large number of objects to be cleaned of various shapes that are sequentially transferred to the conveying device can be thoroughly cleaned automatically from all desired directions, without manual intervention. It is possible to completely eliminate this, reducing work costs and the like.

b Since a rotatable R-axis is attached to the third movable base 17 and the fourth movable base 25 and the fifth movable base 28 are supported by the R-axis, it is possible to provide a cleaning hose pipe within the R-axis. can. Therefore, the cleaning hose does not get in the way and is protected by the R shaft so that it will not be damaged.

c Since the Z-axis balance cylinder 23 is provided for the third movable base 17, the threaded portion 2 of the third movable base 17
The load applied to the third movable base 17 can be reduced and smooth movement can be achieved.
