A suitable number of suction cup support rods 11 extending in the vertical direction are supported on the glass curved surface tracing plate 10 so as to be movable up and down with respect to the tracing plate 10. At the upper ends of these suction cup support rods 11, suction cups 12 are attached. are attached to each. A compression coil spring 13 is interposed between the suction cup 12 and the glass curved surface copying plate 10, and these springs 13 urge the suction cup 12 and the suction cup support rod 11 upward.

A circumference copying drive motor 14 is attached to the base 1 via a motor support member 51 (see Fig. 2), and a sprocket 15 fixed to the rotating shaft of this drive motor 14 is connected to a glass circumference copying machine. Chain 1 attached to the outer surface of side wall 5a of 5
It is engaged with 6. Further, a guide roller 18 is rotatably supported on the base 1 via a roller arm 17 as shown in FIG. is in contact with.

As shown in FIG. 2, an elevating body 20 is supported on the base 1 via a motor support member 51 and a guide member 19 fixed to the member 51 so as to be movable up and down. A pair of curved surface copying rollers 21 and 22 are rotatably supported at the lower end of the elevating body 20, and these rollers 21 and 22 sandwich the peripheral edge of the glass curved surface copying plate 10 from above and below. A cylinder tube 23a of a pressure cylinder 23 consisting of an air cylinder is fixed to the upper end of the elevating body 20 at an appropriate angle tilted from the horizontal direction. Further, a guide rod 24 is supported at the intermediate portion of the elevating body 20 so as to be movable in the same direction as the axial direction of the press cylinder 23.

A vibrating cylinder support plate 25 is fixed to the tip of the rod 23b of the pressing cylinder 23 and the tip of the guide rod 24, and a cylinder tube 26a of a vibrating cylinder 26 consisting of an air cylinder is fixed to the support plate 25. It is fixed at an appropriate angle from the vertical axis. Here, this vibration cylinder 26 constitutes a vibration generator together with a compressor section (not shown) in this embodiment, and when vibrating air pressure is supplied from the compressor section, the rod 26b is vibrated in the axial direction. I'm starting to let them do it.

A head shaft support cylinder 27 is fixed to the vibration cylinder support plate 25. Further, a head shaft 28 is coupled to the tip of the rod 26b of the vibration cylinder 26, and this head shaft 28 is fitted into a bearing 29 fixed inside the head shaft support cylinder 27. is movably guided in the axial direction of the vibration cylinder 26.

2b.

The outer periphery of the upper flange portion 32a has a fourth
As shown in the figure, a first roller group 33 is arranged radially (the rotation axis of each roller of this roller group 33 is perpendicular to the radial direction of the head body 32). Similarly, on the outer periphery of the lower flange portion 32b, a second roller group 34 is arranged radially, as shown in FIG. is perpendicular to the radial direction of the head body 32).

The head stand 3 is mounted on the vibration cylinder support plate 25.
5 is fixed, and this head stand 35 is located below the vibrating head 32. Further, a pair of presser rollers 3 are provided on the vibrating cylinder support plate 25.
6 and 37 are rotatably supported, and these pressing rollers 36 and 37 are arranged in front of the vibrating head 32.

Next, the operation of this embodiment will be explained.

In this device, first, the rubber 8 is manually fitted into the four corners of the glass 9.

Next, the part of the rubber 8 that is not attached to the glass 9 is sandwiched between the presser rollers 36 and 37, and
The rod 23b of the pressing cylinder 23 is pushed out, and the vibrating head 30 presses the rubber 8 against the peripheral edge of the glass 9. At this time, Figs. 6 and 7
As shown in the figure, a rubber 8 is provided between the first roller group 33 and the second roller group 34 of the vibrating head 30.
The vibrating head 30 is engaged with the rubber 8 in such a manner that the lip 8c of the vibrating head 30 is movable relative to the rubber 8 in the longitudinal direction of the rubber 8.

In this state, when the circumference copying drive motor 14 is driven and rotated, the chain 16 is driven by the sprocket 15, so that the glass circumference copying machine 5 is rotated in the direction of arrow A in FIG. However, the outer shape of the side wall 5a of the glass periphery copying machine 5 (that is, the outer shape of the glass 9) is not circular but approximately rectangular, and the positions of the sprocket 15 and the guide roller 18 are fixed with respect to the base 1. Therefore, the rotational movement of the glass periphery copying machine 5 described above is not a rotational movement centered on one fixed point, and one point of the side wall 5a of the copying machine 5 is always aligned with the sprocket 15 and the guide roller 18. This is a rotational motion between the two.

In other words, during the rotational movement of the glass circumference copying machine 5 described above, the shaft 6 serving as the rotation axis of the glass circumference copying machine 5 is such that one point of the side wall 5a of the glass circumference copying machine 5 is always aligned with the sprocket 15 and the guide roller 18. It reciprocates on the rail 2 together with the trolley 3 so that it is between the two.

On the other hand, the glass curved surface tracing plate 10 also rotates integrally with the rotation of the glass periphery tracing plate 5. Due to this rotation, the curved surface copying rollers 21 and 22 and, by extension, the elevating body 20 move up and down in accordance with the curvature of the peripheral edge of the glass curved surface copying plate 10.

As a result, the glass 9 also rotates almost integrally with the glass periphery copying machine 5, so that the vibrating head 30 and the pressing rollers 36, 37 move relatively along the peripheral edge of the glass 9. Further, as a result, the portion of the rubber 9 between the vibrating head 30 and the presser rollers 36, 37 is placed in a tensioned state.

On the other hand, as the rod 26b of the vibrating cylinder 26 vibrates in the axial direction, the head shaft 28 and, by extension, the vibrating head 30 vibrate diagonally in the vertical direction.
As a result, the rubber 8 is continuously moved up and down on the head stand 35. Here, FIG. 6 shows the state of the rubber 8 when the vibrating head 30 is raised, and FIG. 7 shows the state of the rubber 8 when the vibrating head 30 is lowered. The position when raised is approximately the same height as the position of the presser rollers 36 and 37).

As a result of the above, (a) the vibrating head 30 and the presser rollers 36, 37;
moves relatively along the periphery of the glass 9.

(b) The portion of the rubber 9 between the vibrating head 30 and the presser rollers 36, 37 is in a tensioned state.

(c) The rubber 8 is moved to the glass 9 by the vibrating head 30.
It is continuously handled up and down while being pressed against the peripheral edge of the body.

As a result of these conditions being realized at the same time, the rubber 8 is fitted to the peripheral edge of the glass 9.

Then, when the above-mentioned operation is performed on the four sides of the glass 9, the entire work of attaching the rubber 8 to one piece of the glass 9 is completed.

In the embodiment described above, the glass 9 has a mechanism that allows the glass 9 to move up and down while expanding and contracting the spring 13 with respect to the glass curved copying plate. This is to ensure that the mounting operation is performed smoothly.

Further, in the embodiment, the vibrating head 30
The first roller group 33 and the second roller group 34
Since the vibrating head 30 comes into contact with the rubber 8 at these roller groups 33 and 34, the friction acting between the vibrating head 32 and the rubber 8 is reduced, and the vibrating head 30
There is no risk of damaging the rubber. However, in the present invention, it is not necessary to provide the vibrating head with the roller group as in the above embodiment.

〔Effect of the invention〕

As described above, the rubber attaching device for automobile windshields according to the present invention can mechanize most of the work of attaching weather strip rubber to the peripheral portion of automobile windshields, and eliminates so-called spring fingers, which have been a problem in the past. This has the excellent effect of being able to eliminate problems such as disease onset.
