The inspection device 2 is equipped on the front end side of the machine frame 4, and the inspection device 2 can be rotated between a predetermined inspection position and a retracted position spaced from this to the base end side of the machine frame 4. Features.

(Example) The following is an example of implementing the present invention in a coating machine equipped with a coating film inspection device that applies a coating agent, such as a primer, to the surface of a window glass of an automobile, etc. and inspects it, based on the drawings. explain.

1 and 2 show a coating machine 3 equipped with a coating film inspection device 2 using a multi-jointed robot 1. As shown in FIG. The robot 1 has a rotating wrist 1b at the tip of the arm 1a.
and a bent wrist 1c, and the upper end (base end) of the machine frame 4 is connected and fixed to the distal end of the bent wrist 1c via both mounting flanges 5, 6. A coating brush 7 serving as a working means is attached to the lower end (tip). Further, a rotary drive device 8 is attached to the machine frame 4, and this rotary drive device 8
The base end of a swing arm 10 is fixed to the drive shaft 9, and a U-shaped inspection device mounting frame 11 as shown in FIG. 2 is attached to the tip of the swing arm 10. A light receiver 12 and a light projector 13, which constitute the coating film inspection device 2, are arranged vertically in opposition to each other in the single opening of the U-shaped underframe 11.

The coating brush 7 consists of a hollow base cylinder part 7a and bristles 7b whose root parts are bundled into a cylindrical shape and inserted into the hollow base cylinder part 7a. The primer, which is pumped through a valve (not shown), flows into the base cylinder part 7a of the coating brush 7 and is poured out from the bristle part 7b, so that it spreads onto the surface of the glass plate G, which is the workpiece, several mm wide. , thickness of more than 10 μm
It is applied to form a primer coating of about 100%. The coating film inspection device 2 also keeps the state of the primer coating (not shown) applied on the surface of the glass plate G by the coating brush 7 at a constant position on the rear side of the coating brush 7 in the coating progress direction. This optical sensor device is designed to perform inspection at a distance, and as shown in the figure, a light receiver 12 and a light emitter 13 are installed above and below a glass plate G via a U-shaped frame 11. , detects changes in the amount of light received by the light receiver 12 depending on the state of the formed coating film.

The rotation drive device 8 is composed of a pneumatic motor such as a vane motor, and rotates the drive shaft 9 to rotate the rotation arm 10 and the U-shaped underframe 11 attached to the distal end of the rotation arm 10. The paint film inspection device 2 is connected to the drive shaft 9 between the inspection device shown by the solid line in FIG.
It is designed so that it can be rotated around the center. This retracted position is such that when the U-shaped underframe 11 is turned upward as shown in the figure, the lower end portion of the U-shaped underframe 11 is connected to the coating brush 7.
The state should be such that it can be positioned above the lower end of. Incidentally, the glass plate G is held in a fixed position by a suitable support, although not shown.

When using the coating machine 3 with the coating film detection device 2 described above and the coating film inspection device 2 at the same time, the coating brush 7 should be moved against the workpiece in a fixed position, that is, the glass plate G. At the same time, the coating film inspection device 2 is set at a predetermined position on the coated surface of the glass plate G.
The inspection position is set as shown by the solid line in FIGS. Then, while operating the robot 1 and moving the coating brush 7 in a predetermined trajectory along the coating surface of the glass plate G, the primer is coated.
The condition of the paint film of the applied primer is inspected by the paint film inspection device 2, and if there are any scratches or scratches on the paint film, a signal is output, a predetermined abnormality alarm is issued, and corresponding measures are taken. be done.

When the paint film inspection device 2 is not used and only the coating work is performed using the brush 7, the rotary drive device 8
is operated, and the paint film inspection device 2 is pivoted from the inspection position to the retreat position shown by the dashed-dotted line in FIG. Incidentally, it is preferable to provide a locking mechanism for locking the rotating arm or the U-shaped underframe 11 at the respective positions when the coating film inspection device 2 comes to the inspection position and the retracted position.

In the above-mentioned embodiment, a translucent type inspection apparatus was used as a coating film inspection apparatus in which a light emitter and a light receiver were arranged on both sides of a glass plate as an object to be coated. A light reflection type paint film inspection device may be used, which is installed on one side and receives the light from the projector by reflecting it on the paint film. Things become unnecessary.

Further, in the embodiment, only a coating machine equipped with a coating film inspection device was shown, but this is just one embodiment. For example, in a heat sealing machine having a heater as a working means, a seal is placed on the rear side of the heater in the working direction. The present invention is applicable to various types of working machines equipped with inspection devices, such as those equipped with inspection devices for inspecting the condition of parts.

Furthermore, in the embodiment, a working machine was illustrated in which the workpiece is fixed and the workpiece is moved while the machine frame is moved, but conversely, the machine frame itself is fixed and the workpiece is moved. The present invention can also be applied to items that are moved.

(Effects of the invention) According to the work machine with an inspection device of the present invention, since the inspection device is configured to be able to pivot between its predetermined inspection position and the evacuation position, only the work machine can be used. When the inspection device is not in use, the inspection device can be evacuated. Therefore, when the inspection device is not in use, there are no obstacles near the work means, and the work itself can be carried out. This has the effect of making it easier to put in and take out the workpiece, position it, etc.
