SUMMARY OF THE INVENTION An object of the present invention is to provide a device for simply and quickly applying an auxiliary liquid for facilitating the assembling of a window glass when the window glass is assembled to a vehicle body.

[0005]

In order to achieve the above object, an auxiliary liquid applying apparatus according to the present invention comprises a plurality of arms having a base end pivotally supported by a base member about an axis inclined upward. A drive mechanism for swinging or rotating the arm around the axis, a roller supported on the arm and extending in a direction substantially perpendicular to the axis and rotatable about the same direction and having a soft surface, and It has an auxiliary liquid supply mechanism to the roller surface.

Accordingly, when the inclined lower surface of the weather strip attached to the periphery of the window glass for a vehicle is elastically pressed by the roller having a soft surface, the base end pivots on the base member about the axis inclined upward. The plurality of supported arms are rocked or rotated around the axis by the driving mechanism, and the roller moves along the inclined lower surface of the weather strip, so that the roller rotates around its own central axis. While moving, the auxiliary liquid from the auxiliary liquid supply mechanism can be applied to the inclined lower surface of the weather strip reliably and quickly, and a roller having a soft surface extending in a direction substantially perpendicular to the axis is provided by the arm. Swinging or rotating around, the swinging or rotating locus of the roller has a width, and the roller surface can be appropriately recessed Even if the shape of the window glass for a vehicle on which the weather strip is attached to the periphery has a large or small width, and if there is a difference in the three-dimensional curvature of the window glass for a vehicle, the same roller may be used for each of them similarly. An auxiliary liquid can be applied to the weatherstrip surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described by assigning the same reference numerals to the same parts as those of the conventional device. 1 to 3, a base member 11 extending in the horizontal direction is attached to a support post 10 arranged near an assembly line of a vehicle, and at both ends thereof,
A shaft portion 12 that is tilted upward and is rotatable is provided.

Each arm 12 has three arms 13 radially attached thereto in a direction substantially perpendicular to the axis of the arm 12, and a bracket 14 fixed to the tip of each arm 13.
, Two head studs 15 having the same length are slidably inserted at intervals, and an elongate cover 16 is attached to the other end of each stud 15 and the bracket 1
A compression spring 17 is arranged between the cover 4 and the cover 16, and the cover 16 is elastically pressed obliquely upward at right angles to the longitudinal direction of the arm 13 while being parallel to the longitudinal direction of the arm 13, that is, of the shaft portion 12. It is held inclined downward in a direction substantially perpendicular to the axis.

Within each cover 16 is a respective arm 13
A roller 18 is arranged in parallel with the longitudinal direction of the roller. The roller 18 is composed of a shaft tube 19, a urethane sponge layer 20, and a linen skin 21. The shaft tube 19 of the roller 18 has a number of small holes 22 and / or not shown. A narrow groove is appropriately formed, and is supported by the cover 16 so as to be rotatable around its axis, and the inclined outer peripheral surface portion of a substantially upper half of the roller 18 from the axis is exposed outward from the cover 16. The respective rollers 18 are arranged in a plane inclined at substantially the same angle as the angle at which the windshield is attached to the vehicle, which will be described later.

A rubber hose 23, which is wound finely at the lower end of the shaft tube 19 and has a large tolerance for rotation and expansion and contraction, is connected.
3, a suitable amount of soap water having a relatively high viscosity is fed into the shaft tube 19, and the soap water penetrates the urethane sponge layer 20 through a number of small holes 22 and / or narrow grooves to form a skin 21 While the rubber hose 24 is also connected to the lower end of the cover 16,
The soapy water dripped into the cover 16 from the roller 18 is collected downward by the inclination of the cover 16 and is returned to the tank through the rubber hose 24.

Further, the base member 11 includes
A pneumatic cylinder 25 is mounted in parallel with the first arm 13 and the end of the piston rod 26 is connected to one arm 13 and the other two arms 1 adjacent and parallel to each other.
When the piston rod 26 reciprocates due to the operation of the pneumatic cylinder 25, the arms 13 swing about the respective shaft portions 12. And therefore each arm 1
The roller 18 supported by the roller 3 is also configured to swing up, down, left and right around the shaft 12 as shown by arrows in FIG.
The rocking trajectory 8 is included in the inclined one plane.

In contrast to the above device, the windshield 2 of the vehicle having the weather strip 3 attached to the entire periphery as shown in FIG. When the inclined lower surface 31 of the weatherstrip 3 that is held horizontally and conveyed horizontally as indicated by the arrow A in FIG. 1 and protrudes from the windshield 2 is pressed against the outer peripheral surface of each roller 18,
Since the piston rod 26 reciprocates by the operation of the pneumatic cylinder 25, each arm 13 repeats the same swing by the connection of the rod 27.

At this time, in spite of the fact that the windshield 2 is three-dimensionally curved, in addition to the soft surface of the roller 18, the compression spring 17 contracts and each stud 15 slides on the bracket 14. , Windshield 2
Since the roller 18 is rotated while being pressed against the inclined lower surface 31 of the weather strip 3 on the entire periphery, the soapy water that sufficiently wets the roller skin 21 is inclined by the weather strip on the entire periphery of the windshield 2. It is applied to the lower surface 31.

Accordingly, the windshield 2 to which the soapy water has been applied is conveyed by the conveying device 30 to the vicinity of the cab flange 5 on the assembly line, and the string previously fitted along the groove 4 of the weather strip 3 as shown in FIG. By pulling the lip 6 in the lateral direction in order from the end, the lower lip 8 is partially bent as shown by the two-dot chain line in FIG. 4 and the cab flange 5 is continuously fitted into the groove 4. When the outer surface of the lip 8 slides on the upper surface 7 of the cab flange, the outer surface of the lip 8 is less likely to be scratched due to the applied soapy water. The cab flange 5 can be easily fitted into the inside.

As described above, in the roller 18,
The soap water soaks into the urethane sponge layer 20 from the shaft tube 19 to wet the skin 21 with the soap water, and the supply amount of the soap water can be easily adjusted by the size and number of the small holes 22 in the shaft tube 19. And at the same time, by impregnating the urethane sponge layer 20, the soapy water can be fed almost uniformly over the entire surface of the roller 18,
It is easy to always maintain the skin 21 in a necessary and sufficient wet state, and it is possible to apply the soap water to the weatherstrip inclined lower surface 31 without excess and deficiency. It is also possible to easily prevent the vehicle from drooping from 31 and keep the assembly line of the vehicle clean.

Further, since each roller 18 extends long in the inclined plane and swings around the shaft 12 by the arm 13, the roller 18 can apply soapy water over a wide range. Since the soft surface 18 and the contraction of the compression spring 17 and the sliding of each stud 15 with respect to the bracket 14 can easily absorb the difference in the distance to the surface of the roller 18, as shown by the two-dot chain line in FIG. In addition, the dimensions are very different,
Various types of windshields 2 with different three-dimensional curvatures
Soaps can be applied to a, 2b and 2c in the same manner, and the application of the soapy water to the required places can be performed very quickly and accurately by swinging a plurality of rollers 18. In addition, the number of steps required for applying the soapy water can be greatly reduced as compared with the related art, and at the same time, the cab 1 can be prevented from being stained with the soapy water, which is very convenient.

Further, since the outer skin 21 of the roller 18 is made of linen cloth, the rotation of the roller 18 can be facilitated to ensure that a good soapy water is applied, while the roller outer skin 21 is in contact with the outer surface of the weather strip 3. There is an advantage that the life of the roller 18 can be maintained long because the roller 18 is hardly worn even when sliding.

Further, since the cover 16 is disposed below each roller 18, all the soapy water dropped from the roller 18 is received by the cover 16 and is collected downward by the inclination of the cover 16. Since it is returned to the tank through the rubber hose 24, the assembly line of the vehicle can be kept clean also from this surface, and the excess soap water can be recovered to maintain economic efficiency.

In the above embodiment, the outer skin of the roller is made of linen, but it goes without saying that it can be replaced with a material such as cotton cloth which can be sufficiently wetted with an auxiliary liquid such as soapy water. Also, it may be configured so that the auxiliary liquid is appropriately applied or injected to the roller surface between the application of the auxiliary liquid to the weather strip and the next application, or alternatively, each arm supporting the roller may be provided. Even if they are simultaneously rotated only in one direction, the same operational effects as those of the above-described embodiments can be achieved.

[0020]

In the auxiliary liquid applying apparatus according to the present invention, when the inclined lower surface of the weather strip attached to the periphery of the vehicle window glass is elastically pressed by the roller, the plurality of arms swing by the driving mechanism. Or by rotation
The auxiliary liquid from the auxiliary liquid supply mechanism can be applied reliably and quickly to the inclined lower surface of the weather strip while the roller rotates around its own central axis, and the same applies to various types of window glass. Auxiliary liquid can be applied to
Very convenient in practice.
