[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work supporting device mounted on a parallel link mechanism or the like.

[0002]

2. Description of the Related Art As a work supporting apparatus, for example, as shown in FIG. 1, an X-shaped arm b is mounted on a main body a so as to be rotatable about a rotation axis c, and a vacuum suction pad d is mounted on a tip of the arm b. And each of the vacuum suction pads d is connected to the main body 1 with a hose.
Is known in which a workpiece is sucked and supported by a vacuum suction pad d in communication with a vacuum source.

[0003]

SUMMARY OF THE INVENTION It is desired that a work supporting device can support and move a work and can cope with various conditions when the work is separated. For example,
Be able to support flat, vertical and diagonally stacked workpieces.Adjust the workpiece mounting direction and angle when detaching the workpiece. Perform mortise and slit processing while supporting the workpiece. It is desirable to be able to do that. However, the above-mentioned conventional apparatus can only rotate about one axis, so that not only the above-mentioned requirement cannot be satisfied, but also the work having different shapes and dimensions cannot be supported because the relative position of the vacuum suction pad is constant.

Accordingly, an object of the present invention is to provide a work supporting device capable of solving the above-mentioned problems.

[0005]

A first member is rotatably mounted on a first shaft in an X direction provided on a main body, and a second shaft in a Y direction is rotated on the first member. A work supporting device which is freely mounted, a frame 23 is rotatably mounted on a third shaft 22 provided on the second shaft 20 in the Z direction, and a work support is mounted on the frame 23 to remain.

[0006]

[Operation] Place the work support on the first shaft 1 with respect to the main body 10.
1 can rotate, can rotate about the second axis 20, and can swing about the third axis 22, so that the direction of the work support can be arbitrarily changed and the work is supported and separated. Sometimes it can cope with various conditions.

[0007]

[Embodiment] As shown in FIG. 2, a first parallel link 3 is mounted on a base frame 2 rotatably provided on a traveling vehicle 1 so as to be swingable up and down. A two-parallel link 4 is mounted to be swingable up and down to form a balanced link mechanism 5 which is moved by an external force.
A work support device 6 is attached to the tip of the parallel link 4. As shown in FIGS. 3 to 8, the work supporting device 6 includes a main body 10 pivotally attached to a distal end of the second parallel link 4, and a first shaft extending in the X direction (vertical direction) below the main body 10. 11, one side hole 13 of the arm 12 is rotatably mounted around the first shaft 11, and the other side hole 1 of the arm 12 is provided.
A shaft 16 having a block 15 is rotatably fitted to the shaft 4, and the shaft 16 is retained by a retaining pin 17 to form a first member 18. A shaft formed on the block 15 of the first member 18 is formed. The second shaft 20 in the hole 19 in the Y direction (front-back direction)
Are rotatably fitted, and the second shaft 20 is fixed with a nut 21. The third shaft 20 is fixed to the second shaft 20 in the Z direction (left-right direction).
A block 2 in which a longitudinal middle portion of the shaft 22 is fixed, and both longitudinal sides of the third shaft 22 are provided on a pair of frames 23.
A work support, for example, a vacuum suction pad 27 is attached to each frame 23, and the Y-axis rotation bearing is offset forward from the X-axis rotation bearing. However, the Z-axis rotation bearing is offset forward from the Y-axis rotation bearing.

Next, the operation will be described. The first member 18 is
By rotating around the shaft 11, the vacuum suction pad 27 can be swiveled about the first shaft 11, and by rotating the second shaft 20 with respect to the block 15, the vacuum suction pad 27 can be centered on the second shaft 20. In addition, since the Y-axis rotation bearing is offset from the X-axis rotation bearing, the rotation movement range can be increased without interfering with each other, and by rotating the frame 23 around the third shaft 22. Vacuum suction pad 27
Can be swung up and down around the third shaft 22, and since the Z-axis rotation bearing is offset from the Y-axis rotation bearing, the swinging movement range can be increased without interference between the components. Also, by pulling out with the retaining pin 17, the shaft 16 is pulled out.
Can be assembled by inserting a different work support, for example, a clamp attached to the frame 23, from above, so that a different work can be easily replaced and mounted.

[0009]

According to the present invention, the workpiece support can be turned around the first shaft 11, rotated around the second shaft 20, and swung around the third shaft 22 with respect to the main body 10. The direction of the work support can be arbitrarily changed, and various conditions can be met when the work is supported and separated.
