Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a work table device used for collaborative work between an automatic machine such as an industrial robot and a worker.

2. Description of the Related Art For example, as a table device used for adhesive application work, there is a structure shown in FIGS. 8 and 9.

8 and 9 illustrate an example of an apparatus for applying adhesive to the peripheral edge of an automobile windshield. A slide table 2 is provided on a frame 1, and this slide table 2
The sealing robot 3 moves back and forth in a straight line between the glass loading/unloading stage _S1 by the sealing robot 3 and the coating stage _S2 by the sealing robot 3. That is, the slide table 2 is reciprocated by the action of the cylinder 4 via the pinion 5 and the rack 6.

Then, when the worker M sets the window glass W on the slide table 2 at the glass loading/unloading stage _S1 , the suction cup 7 and the plurality of toggle-type clampers 8 position the window glass W, and the slide table 2 is applied as it is. stage
Slide to S ₂ to be positioned. When the slide table 2 is positioned, the sealing robot 3 is operated, and the sealing gun 9 applies adhesive to the window glass W in a bead shape along a previously taught trajectory. When the adhesive application is completed, the slide table 2 is returned to the glass loading/unloading stage _S1 , and
The window glass W is replaced by the worker M.

Problems that the invention attempts to solve In the conventional table device as described above,
The sealing robot must be idle during this time, as the worker will take out the window glass coated with adhesive at the glass loading/unloading stage and replace it with a window glass without adhesive applied. As a result, the operating rate of the robot becomes lower and the cycle time becomes longer.

In addition, in the conventional table device, since a large number of clampers and the like are attached to the slide table itself, these become an obstacle to work on the glass loading/unloading stage, resulting in poor workability.

Means for Solving the Problems The present invention aims to reduce loss time and improve workability at the manual work stage.

Specifically, two slide tables are installed side by side that alternately move linearly between an automatic work stage by industrial robots and other automatic machines and a manual work stage by workers. A positioning reference member is provided to serve as a positioning reference for the workpiece, and a clamp means is provided on the automatic work stage side for pressing and clamping the workpiece against the positioning reference member prior to work being carried out by an automatic machine on the automatic work stage. Structure.

The contents of the work on the automatic work stage and the manual work stage may include, for example, various assembly work, in addition to the adhesive application work and workpiece loading/unloading work shown in the embodiment.

Effect According to the present invention, when one slide table is located on the automatic work stage, the other slide table is located on the manual work stage, so both stages work in parallel. can be done.

Further, since the clamping means for clamping the workpiece is installed on the automatic work stage, it does not interfere with work on the manual work stage.

and the glass loading/unloading stage _S1 as a manual work stage by the worker M.

Further, a clamper 17 as a clamping means is provided on the base 10 at a position corresponding to the adhesive application stage _S2 . Then, when either of the slide tables 12A, 12B on which the rear quarter glass W (FIG. ₆ ) is placed as a workpiece moves to the adhesive application stage _S2 in the glass loading/unloading stage S1, the sealing robot 3 applies the adhesive. Clamper 1 before applying the agent
7 positions the rear quarter glass W on the slide table 12A or 12B.

Figures 3 to 6 show slide tables 12A and 1.
2B, in which a plurality of vacuum cups 18 and pads 19 are erected on slide tables 12A and 12B, and a toggle clamp mechanism 20 is provided in the center.

The toggle clamp mechanism 20 is shown in FIGS.
As shown in the figure, there is a clamp rod 22 that reciprocates by the action of a cylinder 21, a link 23 pivotally supported in a pair on the clamp rod 22, and a link 25 pivotally supported in a pair on a bracket 24 on the slide table side. It is mainly composed of
Then, as shown in FIG. 6, the adjacent link 2
3 and 25 are connected to each other to form a four-bar link mechanism, and a clamp roller 26 as a positioning reference member is installed at the connection portion between the links 23 and 25.
It is pivoted. Therefore, each clamp roller 26 is displaced in accordance with the movement of the clamp rod 22. In addition, 27 is the clamp rod 22
The guide roller 28 regulating the movement is a fixed positioning block.

29 is a movable positioning block provided at a position corresponding to the fixed positioning block 28. This movable positioning block 29 is supported by a bracket 30, and is moved by the action of a cylinder 31 fixed to the base 10. Bracket 3
It is configured to move every 0. 32 is a guide bar.

As shown in FIGS. 6 and 7, the clamper 17 has a pair of clamp rollers 34 attached to the tip of an arm 33, and the arm 33 itself is rotatably supported on a bracket 35 on the base 10 side. It is. Since the base of the arm 33 is connected to the piston rod 36a of the cylinder 36, the arm 33 is connected to the piston rod 36a of the cylinder 36.
It rotates around the shaft 37 due to the action of .

The table device configured as described above operates as follows.

In FIGS. 1 and 2, two slide tables 12A and 12B are glass loading/unloading stages.
Since it reciprocates alternately between _S1 and the adhesive application stage _S2 , for example, if one slide table 12A is located at the glass loading/unloading stage _S1 , the other slide table 12A
B is located at adhesive application stage _S2 .

Then, the operator M sets two rear quarter glasses W onto the slide table 12A on the glass loading/unloading stage _S1 with reference to the clamp roller 26 and the positioning block 28 located at the solid line position in FIG. 6. The positioning at this time is relatively rough and sufficient, and once the glasses W are set, the vacuum cup 18 suctions and supports the glasses W.

Subsequently, the cylinder 15 is activated, and one slide table 12A, on which the rear quarter glass W is set, moves from the glass loading/unloading stage _S1 to the adhesive application stage _S2 , and at the same time, the other slide table 12B starts applying the adhesive. Move from stage S ₁ to glass loading/unloading stage S ₁ .

When one slide table 12A moves to the adhesive application stage _S2 and stops, the vacuum cup 18 releases the rear water glass W, and the arm 33 of the clamper 17, which was waiting at the imaginary line position in FIG. The cylinder 36 rotates, and the clamp roller 34 comes into contact with the end surface of the glass and presses it. As a result, the two rear quarter glasses W are positioned in the width direction by the action of the clamper 17 and the toggle clamp mechanism 20. Ru.

Furthermore, the positioning block 29 moves forward due to the action of the cylinder 31, and presses the rear quarter glass W against the positioning block 28 on the fixed side. As a result, both positioning blocks 28, 2
9 positions the rear quarter glass W in the longitudinal direction.

After the completion of the positioning as described above, the sealing robot 3 is activated to apply adhesive to the peripheral edge of the rear quarter glass W using the sealing gun 9.

In parallel with the work in the adhesive application stage _S2 , in the glass loading/unloading stage _S1 , the worker M sets the rear quarter glass W on the other slide table 12B in the same manner as described above.

Once the work in adhesive application stage S ₂ is completed,
While the vacuum cup 18 again attracts the rear water glass W, the clamper 17, toggle clamp mechanism 20, and positioning block 29 each perform an unclamping operation.

At this time, since the glass setting work for the other slide table 12B has been completed, the slide table 12A on which the adhesive application work has been completed is placed on the clamper ₁ side on the adhesive application stage S2.
7 and the positioning block 29 remain, the glass loading/unloading stage is moved by the action of the cylinder 15.
While moving to S ₁ , the other slide table 12
B moves to adhesive application stage _S1 .

Then, in the adhesive application stage _S2 , adhesive application work is performed on the rear water glass W on the slide table 12B in the same manner as described above, and on the other hand, in the glass carrying-in/out stage _S1 , the glass coated with adhesive is carried out. , new glass without adhesive applied thereto is carried in, and the above operations are repeated thereafter.

Here, the glass coated with adhesive is carried out using a predetermined jig. That is, a jig with a vacuum cup (not shown) held by the worker M is placed into the lower surface of the rear water glass W, and the glass is suction-supported, and the worker then adhesively fixes it to the glass opening of the vehicle body. In this case, since there is no clamper 17 or positioning block 29 on the glass loading/unloading stage _S1 , there is no obstacle to the work, and workability is excellent.

Effects of the invention As described above, according to the invention, the automatic work stage and the manual work stage can perform work in parallel, thereby shortening the cycle time. Since there is no clamping means that is likely to cause damage, workability is good and the burden on the worker can be reduced.
