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. After waiting for the slide table 2 to be positioned, the sealing robot 3 is activated, 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
A worker M replaces the window glass W.

Problems to be solved by the invention In the conventional table device as mentioned 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 conventional table devices, a large number of clampers and the like are attached to the slide table, and it is assumed that the slide table itself is horizontal. For this reason, the basic structure of these slide tables tends to become a hindrance to work, and in particular, when handling heavy items such as window glass, the worker is forced into an unreasonable posture, resulting in poor work efficiency.

Means for Solving the Problems The present invention has a turntable structure with two workpiece holders, so that an automatic work stage by an industrial robot or the like and a manual work stage by an operator can be performed simultaneously. do the work,
Furthermore, by tilting the table itself, the workability of the manual stage is improved.

Specifically, two workpiece receiving parts are formed,
and a turntable that rotates between an automatic work stage by an automatic machine and a manual work stage by an operator, so that when one workpiece receiving part is located on the manual work stage, the other workpiece receiving part performs automatic work. In a work table device configured to be located on the stage, the turntable is arranged such that the height of the workpiece receptacle located on the manual work stage is lower than the height of the workpiece receptacle located on the automatic work stage. The rotation center of the automatic work stage is tilted with respect to the horizontal plane, and the automatic work stage is provided with positioning and clamping means for positioning and clamping the workpiece to be worked on the automatic work stage.

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

Effect According to the present invention, when one workpiece receiving part is located on the automatic work stage, the other workpiece receiving part is always located on the manual work stage, so that both stages perform parallel work. work can be done.

Furthermore, in the manual work stage, the worker always faces the turntable in a forward-leaning position, and performs predetermined work in this position.

Embodiment FIGS. 1 and 2 are diagrams showing a more specific embodiment of the present invention.

In FIGS. 1 and 2, reference numeral 10 denotes a base frame whose upper plane is inclined, and a turntable 11 in an inclined position is disposed on this base frame 10. As shown in FIG. As will be described later, the turntable 11 has a rotational movement function in addition to an elevating movement function, and has an adhesive application stage _S2 as an automatic work stage by the sealing robot 3,
The glass loading/unloading stage _S1 , which is a manual work stage by the worker M, is rotated forward and backward.

Further, the base frame 10 is provided with a positioning mechanism 12 as a positioning clamp means at a position corresponding to the adhesive application stage _S2 . is positioned on adhesive application stage _S2 .

3 to 5 show the details of the turntable 11. A rotation shaft 13 inclined at a predetermined angle toward the glass loading/unloading stage _S1 is erected on the base frame 10. A lift rod 14 is disposed within the rotation shaft 13 and is movable relatively only in the axial direction.

At the upper end of the lift rod 14 is a table body 15.
are fixed, and table arms 16a, 1 as workpiece receiving parts are mounted on both sides of the table body 15.
6b are connected to each other. The table arms 16a, 16b are the table main body 15
Since it is hingedly connected with the pin 17, it is possible to rotate it in the vertical direction from the state shown in FIG. However, in the normal state, the movable stopper 1 on the table arm 16a, 16b side
8 is held in the position shown in FIG. 3 by coming into contact with a fixed stopper 19 on the table body 15 side.
Note that 20 is a balance weight arranged at the base of the table arms 16a, 16b.

Further, pads 21 for positioning the window glass W are provided on the table arms 16a and 16b.
In addition to Rough Guide 22, Bakyum Cup 23
is provided.

A pinion 24 is fixed to the base of the rotating shaft 13, and the base frame 10 is provided with a rack 26 that reciprocates by the action of a cylinder 25. Since the rack 26 is engaged with the pinion 24, the reciprocation of the rack 26 causes the turntable 11 to rotate forward and backward by 180 degrees.

Here, a pair of stoppers 2 are provided on the rotating shaft 13.
7 and 28 are provided, and on the other hand, a pair of cylinders 31 provided with stopper levers 29 and 30 are provided on the base frame 10 side. Therefore, when the turntable 11 is rotated in the forward or reverse direction, the stopper 27 and the stopper lever 29 or the stopper 28 and the stopper lever 30 come into contact with each other, thereby regulating the forward and reverse positions. In this case, each cylinder 31 also functions as a shock absorbing damper.

A pair of lift cylinders 32 are provided integrally with the rotation shaft 13 on both sides of the rotation shaft 13, and the piston rods 32 of these lift cylinders 32
a is connected to the table body 15. Therefore, the entire turntable 11 except the rotating shaft 13 moves up and down by the action of the lift cylinder 32.

6 and 7 show details of the positioning mechanism 12, the frame 33 on the base frame 10 includes a plurality of pads 34 and vacuum cups 35 for positioning the window glass W, as well as a plurality of clampers 36. ,37,3
8 and 39 are provided. Clamper 36,3
7 is provided with a roller 41 at the tip of each clamp lever 40, and the window glass W is pressed and clamped by the action of a cylinder 42.
Similarly, the clampers 38 and 39 are equipped with a roller 43 at the tip of the piston rod, and the cylinder 4
The function of 4 presses and clamps the window glass W.

The table device configured as described above operates as follows.

In FIGS. 1 and 2, if the table arm 16a of the turntable 11 is located at the glass loading/unloading stage _S1 , the other table arm 16b is located at the adhesive application stage _S2 . In this case, as described above, the rotating shaft 13
is tilted and the entire turntable 11 is in a forward tilted position, so the table arm 16a on the glass loading/unloading stage _S1 is at a lower position than the other table arm 16b.

Then, at the glass loading/unloading stage _S1 , the worker M places the window glass W on the table arm 16a.
When the turntable 11 is placed and positioned, the turntable 11 is raised by the action of the lift cylinder 32 shown in FIG.

Subsequently, when the cylinder 25 is extended, the turntable 11 is rotated 180 degrees in the A direction via the rack 26 and pinion 24. As a result, the table arm 1 with the window glass W positioned
6a moves to adhesive application stage S ₂ , and table arm 1, which was previously in adhesive application stage S 2, moves to adhesive application stage S ₂ .
6b is located at the glass loading/unloading stage _S1 .

When the turntable 11 rotates normally as described above, the turntable 11 is lowered again by the action of the lift cylinder 32. As a result, in the adhesive application stage _S2 , the table arm 16a
The window glass W supported by the window glass W is transferred to the positioning mechanism 12 shown in FIGS. 6 and 7.
That is, interference between the turntable 11 and the positioning mechanism 12 is prevented by using both the rotational movement and the vertical movement of the turntable 11 as described above.

When the window glass W is positioned by the positioning mechanism 12, the window glass W is clamped by the clampers 36 to 39 and the vacuum cup 35 shown in FIGS. 6 and 7. The sealing robot 3 then operates to apply adhesive to the peripheral edge of the window glass W using the sealing gun 9.

In parallel with the work in the adhesive application stage _S2 , the worker M places the window glass W on the other table arm 16b in the glass loading/unloading stage _S1 .

Once the work in adhesive application stage S ₂ is completed,
Wait until each clamper 36 to 39 of the positioning mechanism 12 performs an unclamping operation, and then turn the turntable 1.
1 rises. As a result, the window glass W on the positioning mechanism 12 returns to the original table arm 16.
Transferred to a.

When the turntable 11 rises, the cylinder 2
5, the turntable 11 is reversed, and the table arm 16a supporting the window glass W coated with adhesive is transferred to the glass loading/unloading stage _S1 to similarly support the window glass W not coated with adhesive. The table arms 16b are respectively located at the adhesive application stage _S2 .

Then, after waiting for the turntable 11 to descend, adhesive application work is performed in the same manner as above at the adhesive application stage _S2 , while at the glass loading/unloading stage _S1 , the window glass W coated with the adhesive is is carried out, and a new window glass W to which no adhesive has been applied is carried in, and the above-mentioned operations will be repeated thereafter.

Here, the work on the glass loading/unloading stage _S1 is carried out by two workers in cooperation because the window glass itself is heavy. In this case, the turntable 11 itself is tilted forward, and there are fewer obstacles such as the positioning mechanism 12 on the glass loading/unloading stage _S1 , which greatly contributes to improving workability.

Effects of the invention According to the invention, it is possible to shorten the cycle time by being able to perform work in parallel on the automatic work stage and the manual work stage. It has good workability, reduces the burden on the worker, and is especially suitable for handling heavy items such as window glasses.

In addition, since the workpiece positioning clamp means is arranged only on the automatic work stage and there is no positioning clamp means on the manual work stage side, this also works with the fact that the turntable itself is tilted so that the manual work stage side is lower. Therefore, the positioning clamp means does not become an obstacle during manual work, and workability on the manual work stage can be further improved.
