Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a device for applying an adhesive to a window glass for an automobile so as to attach the glass to an automobile body.

(Prior Art) Among window glasses for automobiles, there is an adhesive window glass that is attached to an automobile body by an adhesive agent such as urethane.

To attach such an adhesive wind glass to an automobile body, for example, convey the wind glass, apply an adhesive to the wind glass by an adhesive application device body such as an adhesive application robot during the transportation, and then attach it to the automobile body. It is conceivable to carry out by a transport attachment line configured as described above.

As a conventional device for applying an adhesive agent to a window glass, a positioning attachment is provided on a device body base, and the glass is placed on the base, as described in Japanese Utility Model Laid-Open No. 60-54677. An apparatus for moving the positioning attachment to position the glass, and then automatically applying an adhesive by a robot or the like, JP-A-58-156367, or JP-A-6-58.
As described in Japanese Patent Application Laid-Open No. 0-29492, a positioning pin is provided on the turntable of the apparatus, and an operator places the glass on the turntable and abuts on the positioning pin to position the glass. A device or the like for automatically applying an adhesive has been proposed.

When attempting to automatically perform adhesive application by means of an adhesive application device body such as a robot, usually the application device body is taught so that proper application can be performed assuming that the glass is in the proper position. Therefore, it is necessary to apply the adhesive after positioning the glass at the proper position.

Therefore, it is desirable to apply the adhesive on the transport attachment line as described above as quickly as possible and in a short time.

This is because the adhesive application process is usually one of the most time-consuming processes in the wind glass transportation installation line, and if this adhesive application process can be performed in a short time, the speed of the entire line should be increased. This is because, on the contrary, if it takes a long time to apply the adhesive, the speed of the entire line will be reduced.

However, all of the above-mentioned conventional adhesive application devices perform positioning and adhesive application at the same position on the device. Therefore, in applying adhesive, first positioning and then adhesive application must be performed. However, there is a problem that the adhesive application process as a whole requires a time obtained by adding the positioning time and the adhesive application time, which requires a long time for the adhesive application process.

In this case, for example, the adhesive application process may be performed in a streamlined manner, and the positioning and the adhesive application may be simultaneously performed at different positions to reduce the time required for the entire adhesive application process.

However, the conventional flow operation of the adhesive application step is to successively convey glass to each work position by itself as described in Japanese Utility Model Laid-Open No. 60-54677, for example. In the above, there is a possibility that the glass may be displaced when it is delivered to and from the transport device. Therefore, using such a conventional flow work method,
Even if an attempt is made to adopt a configuration in which the positioning and the adhesive application are performed at different positions at the same time, there is a possibility that a misalignment occurs when the positioned glass is conveyed from the positioning position to the adhesive application position by the conveying means and delivered to the position. Therefore, it is difficult to adopt such a configuration, and even in this conventional example, the adhesive application position is configured such that the glass is first received, first positioned, and then the adhesive is applied.

Further, in the above-described window glass conveying / attaching line, it is desirable to be able to handle glass having different sizes and shapes such as windshield and rear glass or glass of other vehicle types at the same time, that is, one line. This is because it is inefficient to install a transportation attachment line for each glass having different sizes, shapes, etc. in various aspects such as line installation space, line construction cost, operation and maintenance.

However, as mentioned above, 1 glass with different size, shape, etc.
When handled in one line, different glasses have to be positioned at different regular positions, and from the viewpoint of speeding up the line, such different regular positions can be easily and quickly positioned. Is desirable.

(Object of the Invention) In view of the above circumstances, an object of the present invention is to reduce the time required for the adhesive applying step and to position the glass at the regular position required in the adhesive applying step on various different glasses. On the other hand, it is an object of the present invention to provide a window glass adhesive application device for an automobile, which can be easily and quickly performed.

(Structure of the Invention) In order to achieve the above object, an apparatus for applying an adhesive agent for an automobile window glass according to the present invention is an apparatus for applying an adhesive agent to an automobile window glass, and includes a base portion and a horizontal plane on the base portion. A glass support table provided with a pallet portion that is movably supported by a pallet, and a glass holding device that holds the window glass provided on the pallet portion, and the glass support table is bonded from a positioning position via the base portion. A glass support platform transporting device for transporting to the agent application position, and a positioning device provided at the positioning position.
A positioning device that comes into contact with the outer peripheral surface of the window glass held by the holding device to position the window glass together with the pallet portion at a predetermined position with respect to the base portion, and the positioning device is provided on the glass support base. A lock device for fixing the pallet portion positioned at a predetermined position with respect to the base portion to the base portion at the predetermined position, and provided at the adhesive application position, and conveyed to the adhesive application position through the glass support base. And a main body of an adhesive applying device for applying an adhesive to the wind glass.

The predetermined position when the windshield is positioned at the predetermined position with respect to the base by the positioning device means that the base is conveyed to the adhesive application position while being positioned at the predetermined position with respect to the base. Then, it means a position with respect to the base portion where the window glass becomes a regular position at the adhesive application position.

(Advantages of the Invention) As described above, the vehicle window glass adhesive application device according to the present invention conveys the window glass from the positioning position to the adhesive application position, and positions or conveys the window glass at the positioning position. The positioning of the wind glass at a predetermined position with respect to the base is configured so that the adhesive application is performed at the adhesive application position, in other words, the adhesive application and the positioning are performed at different positions. These can be performed in parallel, and as a result, whichever is longer becomes the adhesive application process time, and the time of the entire adhesive application process can be significantly shortened.

In particular, the vehicle window glass adhesive application device according to the present invention does not transport glass alone as described above, but installs it on the base and a pallet part movably supported by the base and the pallet part. And a glass holding device (in the following embodiments, a glass shape correcting device corresponds to this), and a glass supporting table provided with a locking device for fixing the pallet section to the base section. Since it is configured to convey the glass through the, the glass is positioned at the regular position on the support base on the support at the positioning position and locked by the locking device, and then the glass is bonded together with the support. It is possible to convey the glass to the agent application position, and by doing so, when the glass is conveyed to the adhesive application position, the glass can be in a state of being positioned at the regular position, It is possible to perform the positioning and the adhesive application at different positions, which were difficult when the glass is conveyed alone as in the above-mentioned conventional technique, and it is possible to shorten the adhesive application process time as a whole. be able to.

Further, at the positioning position, a glass positioning device that holds the glass movably on the glass support base and contacts the outer peripheral surface of the glass to position the glass at a regular position with respect to the base is the glass support base. Since they are separately provided, positioning can be easily and quickly performed on various glasses having different sizes and shapes.

That is, according to the present invention, since the positioning device is provided separately from the glass supporting table which is carried on the carrying line, the setting change of the position to be positioned, which is required every time the type of glass is changed, is simply performed by the positioning device. It is possible to deal with this by simply changing the set position on the side, that is, changing the contact position with the outer peripheral surface of the glass, and it is not necessary to change the operation of the support base, and it can be performed very easily and quickly. (Since the positioning device of the present invention is provided separately from the glass support base, the setting position can be changed easily and quickly, but if the positioning device is provided on the glass support base, The glass support has a complicated structure to some extent to exert various other functions, so it is generally troublesome to change the setting position of the positioning device. In addition, the setting position of the positioning device can be changed at the same time in parallel with the glass transportation by the supporting table, so that the positioning time can be shortened accordingly. If it is provided, the setting change must be performed on the glass support base side, and therefore, the glass positioning must be performed after the setting change on the glass support base side, so that the entire positioning time becomes long).

Further, the glass support has a complicated structure to some extent to exert various other functions, and if a positioning device is further provided on the glass support, the structure of the glass support becomes extremely complicated. In the present invention, since the positioning device is provided separately from the glass support base, the structure of the support base can be simplified.

Further, if a positioning device is provided on the glass support base, a positioning device must be provided for each support base. In the present invention, however, since the positioning device is provided separately from the glass support base, there is only one positioning device. It does not need to be provided for each glass support.

In short, since the present invention is configured to convey the wind glass through the glass support table and position the glass on the support table, the positioning and the adhesive application can be performed at different positions. And, by doing so, the time for the adhesive application process can be shortened.
In addition, since the positioning device is provided separately from the support at the positioning position, it facilitates and speeds the positioning of the glass when different types of glass are conveyed in a mixed state, and simplifies the configuration of the support. It is possible to avoid installing a positioning device for each support.

28 Glass shape correction device 445 provided on the below-mentioned
Since the glass support base 42 is fixed by suction onto the glass support 42, the glass support base 42 can movably support the glass 2 via the pallet portion 428.

Further, as shown in FIGS. 5 and 6 (not shown in FIG. 7), the pallet portion 428 is fixed to the base portion 422 on the base portion 422, in other words, the glass 2 sucked and fixed to the pallet portion 428. A lock device 431 for fixing the to the glass support 42 is fixed.

The locking device 431 includes a rod 433 which is moved in the direction of arrow H by a cylinder 432, a pinion 435 which meshes with a rack portion 434 formed at the tip of the rod 433, and a female formed on the inner surface of the pinion 435. A lock member 437 having an external thread portion 436 that is screwed with the thread portion on the outer surface,
The lock member 437 has a pressing plate 439 that penetrates a hole 438 formed in the pallet portion from below the pallet portion 428 and projects upward, and presses the pallet portion 428 against the projecting portion.

The pallet portion 428 has a plurality of positioning reference members 440, 441, 442 having a glass contact surface arranged along the regular shape of the glass on the upper surface thereof, and the positioning reference members are brought into contact with the glass. The glass shape correcting device 445 including the glass sucking means 443 and 444 is provided.

The window glass 2 is placed on the pallet portion 428 and conveyed to the adhesive application position 20 described above, and the adhesive application device main body 28 automatically applies the adhesive at the position 20. In this case, since the main body 28 of the adhesive coating device is taught to perform the proper adhesive coating on the assumption that the glass 2 has a regular shape, if the glass 2 has a deviation from the regular shape, a coating film is formed. Application unevenness such as thickness variation occurs. Therefore, it is desirable that the glass 2 be corrected to the normal shape before the adhesive is applied, and the shape correction device 445 is a device therefor.

The glass 2 transferred from the first transfer device 14 to the glass support table transfer device 4 is first transferred to the shape correction position 16 of the transfer device 4.
The shape correction device 445 of the glass support table located at the position, particularly the positioning reference members 440 to 442, is mounted on the position correction member 440, 442, and then the suction means 443, 444 sucks the positioning reference members 440 to 442 securely. It is made to abut. By doing so, since the glass contact surfaces of the positioning reference members 440 to 442 are arranged along the regular shape of the glass as described above, the shape of the glass 2 is corrected to the regular shape.

The positioning reference member is specifically shown in FIGS.
As shown in the drawing, the flat surface reference members 440 and 441 are in contact with the lower surface of the flat surface of the glass, and the curved portion reference member 442 is in contact with the lower surface of the lateral curved portion of the glass. Also,
The flat reference member is a fixed reference member 440 fixedly arranged.
And a movement reference member 441 movable in the Y direction,
Both 440 and 441 are made of a ball member that is held in a regular position by a stopper 446 and a spring 447. The movement reference member 441 is provided on a moving bar 449 that moves on a guide rail 448 extending in the Y direction, and the cylinder 45
By moving the moving bar 449 by 0, the moving bar 449 is moved in the Y direction. For example, 441 shown by a chain double-dashed line in FIG.
Positions such as a and 441b can be taken. Also, the curved portion reference member 442
Is a pin member, each of which is provided on an arm 451 and is positionally movable in the direction of arrow I by a cylinder 452 via the arm 451 as shown in FIG.
Further, it itself can move in the arrow J direction with respect to the arm 451 and further can move in the Y direction via the arm 451 along the guide bar 453 as shown in FIG.

The glass suction means is specifically composed of a flat surface suction means 443 for sucking the lower surface of the glass flat surface portion and a curved portion suction means 444 for sucking the curved portion of the glass side surface, both of which suck glass by vacuum. It consists of a sucker. Although the flat portion suction means 443 is fixedly arranged, the curved portion suction means 444 is provided.
Is provided on the arm 451 similarly to the bending portion reference member 442, and therefore, like the bending portion reference member 442, arrow I,
It can move in the J and Y directions.

The reference member and part of the suction means are configured to be movable as described above in order to accommodate various glass shapes.

After the glass 2 is sucked and fixed on the pallet portion 428 of the glass supporting table 42 as described above and the shape is corrected, the supporting table 42 is then moved to the positioning position 18, where the glass 2 together with the pallet portion 428 is the base. It is positioned at a predetermined position with respect to 422.

That is, although the glass 2 is automatically applied with the adhesive applying device main body 28 at the next adhesive applying position 20,
In this case, since the coating device main body 28 performs the adhesive application on the assumption that the glass 2 is in the regular position at the coating position 20, if the glass is not in the regular position, the adhesive is not applied to the proper place of the glass. If not performed, coating unevenness occurs. Therefore, the glass 2 needs to be in the regular position when the adhesive is applied, and the glass positioning position
Positioning for that purpose is performed at 18.

The glass predetermined position to be positioned with respect to the base portion 422 at the glass positioning position 18 is such that when the base portion 422 is conveyed to the adhesive application position 20 while being positioned at the predetermined position with respect to the base portion 422, the adhesive agent The base portion so that the window glass 2 at the application position 20 becomes the adhesive application regular position.
This is a position with respect to 422, and by positioning the glass at the glass transfer position (glass positioning position 18) before the adhesive application position 20 in this way, the transfer time of the glass 2 is greatly shortened. Because the positioning of the glass takes some time, and if this positioning is the adhesive application position
If this is done at position 20, both this positioning and the application of adhesive must be performed at position 20, so the glass stop time at position 20 becomes longer, and as a result, the glass support 42 in the glass support carrier 4 is transported. This is because the speed becomes slower overall.

The positioning of the glass, the glass support 42 described above,
This is performed with the glass positioning device 26 disposed above the glass support table 42 at the positioning position 18.

This glass positioning device 26, as shown in FIGS. 8 and 9, contacts the X-direction outer peripheral surface 2a of the glass and positions the glass in the X-direction by holding the X-direction holding rollers 454, 455.
And Y-direction holding rollers 456 to 459 for contacting the Y-direction outer peripheral surface 2b and positioning the Y-direction position.
All of 454 to 459 are supported via a base portion 460, and are vertically movable by a cylinder 461 via the base portion 460.

The X-direction rollers 454 and 455 can be expanded and contracted in the X direction, and the Y-direction rollers 456 to 459 can be expanded and contracted in the Y direction. Expansion and contraction of the X-direction rollers 454 and 455 are performed by expansion and contraction of a rod 463 by a cylinder 462 fixed to the base 460, as shown in FIG. That is, when the rod 463 moves left in FIG. 9, the left roller 454 moves left via the bracket 464, and at the same time, the upper rod 46 having the rack portion 465a.
5 moves to the left and moves to the rack section 46 via the pinion 466.
The lower rod 467 having 7a moves to the right, which moves the right roller 455 to the right through the bracket 468, so that both rollers 454 and 455 expand in the X direction. When the rod 463 is contracted and moved to the right by the cylinder 462, both rollers 454 and 455 are contracted and closed in the X direction. Y direction roller 45
6 to 459 are expanded and contracted in the Y direction as shown in FIG.
1 through the cylinders 469 and 470 fixedly mounted on the cylinder 1, that is, the cylinder 469 moves the left rollers 456 and 457 in the Y direction in the arrow K direction and the cylinder 470 moves the right rollers 458 and 459 into the arrow L
This is done by moving in the direction.

The positioning of the glass 2 by the positioning device 26 configured as described above is performed as follows. That is, first, each of the rollers 454 to 459 waits in a state of being expanded in the X direction and the Y direction and lifted upward by the cylinder 461. Next, the glass support table 42 moves to a position below the positioning device 26 (positioning position 18). In this glass support table 42, the glass 2 is sucked and fixed by the glass shape correcting device 455 on the pallet portion 428 as described above, and the pallet portion 428 is movable in the X, Y and θ directions.

The glass on the glass support table 42 located at is then gripped, and then the arm 30b is rotated upward by 180 ° around the axis 30a, whereby the adhesive application surface, which has been the upper surface until now, becomes the lower surface. Then, the glass 2 is inverted.

Next, the glass 2 inverted by this inversion device 30
Car body by wind glass mounting robot 32
Mounted automatically to 12. The robot 32 mounts glass on both the front and the rear by one unit.

As described above, the automobile body 12 is the transportation device 13 shown in FIG.
Both the windshield and the rear glass are mounted while being transported to the glass mounting position 50 set on the transporting device 13 and stopped there by the pitch feeding.

As shown in FIGS. 1, 2, and 4, the mounting robot 32 has a base 32a and an arrow m attached to the base 32a.
Vertical movement in the direction, and the arrow theta ₂ direction of rotatable arm member 32b around the rotation and axial n ₂ of arrow theta ₁ direction around the axis n _1, attached to the tip of the arm member 32b arrow theta ₅ around the arrow theta ₃ direction of rotation about the axis n _3, the rotation and axial n ₅ of the arrow theta ₄ direction about the axis n ₄ Te
And a glass holding portion 32c rotatable in any direction, and the mounting robot 32 as a whole is mounted between a front window glass mounting position 54 and a rear window glass mounting position 56 by a moving mechanism by a motor 52 or another moving mechanism. Can be moved.

The windshield mounting robot 32 lifts the windshield 2c from the glass supply position 58 (the position where the glass is reversed and held by the reversing device) at the rear windshield mounting position 56, and then the windshield mounting position 54 is located at the windshield mounting position 54. The windshield 2c is attached at the position 54, then the rear window glass attachment position 56 is returned, and the rear glass 2d is lifted from the glass supply position 58 at the position 56 to attach the glass 2d. Of course, the above-mentioned glass lifting and mounting are performed by the arm member 32b and the glass holding portion 3.
Perform while rotating 2c appropriately.

The above description is for the case of the adhesive type wind glass, and in the case of the seal rubber type wind glass, as described above, the glass is supported by the glass support table 42 and conveyed to the reversing position 22 without passing through.
The glass mounting position 34 by the transfer device 36 and the rear transfer device 6
Be transported to.

The second transfer device 36 transfers the glass by the glass suction means 36a which moves and rotates in the directions of arrows P and D. The third transfer device 64 also transfers glass by a similar glass suction means (not shown).

When the glass mounting robot fails, as described above, the adhesive window glass is also transferred to the glass mounting position 34 by the second transfer device 36 and the rear transfer device 6 together with the seal rubber type window glass. Glass reversing device
If the 30 fails, you can deal with it in a similar way.

As described above, in the window glass adhesive coating device for an automobile according to the present invention, the glass is configured to be movable and lockable on the glass support base, and is conveyed through the glass support base, whereby the glass is Since the positioning and the adhesive application are performed at different positions, the positioning and the adhesive application can be performed in parallel, and the overall adhesive application process time can be shortened. Is.

In addition, since the glass positioning device is provided separately from the glass support base at the glass positioning position, the dimensions and
Even glass with different shapes can be handled by changing the operation of only the glass positioning device side, and there is no need to change the glass support base, so positioning can be done easily and quickly. It is possible to simplify the configuration and avoid providing a positioning device for each glass support.

The present invention can be modified in various ways within the scope of the invention and is not limited to the above embodiments. For example, the movable structure of the glass on the glass support table and the structure of the positioning device can be variously changed.
