Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a suction pad for sucking a work, or for holding and transporting the work after suction.

[Prior Art] Conventionally, for example, a suction pad connected to a vacuum suction source has been used to convey a thin plate-shaped work.

The suction pad is fixed to the vacuum suction source adapter with a screw or the like from the suction surface side.

FIG. 3 shows a suction pad according to this type of prior art. In the figure, the suction pad 2 has a skirt portion 4 and a cylindrical base portion 6, and is fixed via a hollow screw 7 to an adapter 8 that defines a passage communicating with a vacuum suction source (not shown). There is.

[Problems to be Solved by the Invention] However, in this type of suction pad, for example,
When various suction pads are selected and used for the work, there is a drawback that the suction pad cannot be easily replaced if the gap between the suction surface and the work is small.

The present invention has been made in order to solve this kind of problem, and a rib is provided on the outer periphery of the root part that constitutes the suction pad, an adapter is inserted into the root part, a lock ring is fitted, and a rib is formed. It is an object of the present invention to provide a suction pad that can be easily exchanged by obtaining a locked state between the lock pad and the lock ring, and thus integrating the suction pad and the adapter.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a suction pad for sucking a workpiece, wherein the suction pad is a flexible member connected to a vacuum suction source. A root portion, a skirt portion integrally formed with the root portion, and a lock ring engaged with the root portion. The root portion is engaged with the lock ring on the outer circumference. It is characterized in that it is provided with a rib for.

[Operation] When the adapter connected to the vacuum suction source is inserted into the root part of the suction pad according to the present invention and the lock ring is engaged with the rib on the outer circumference of the root part, the root part is bent and the tip of the adapter is bent. The outer peripheral surface of the portion is strongly pressed, whereby the suction pad and the adapter are attached to each other.

[Embodiment] Next, a preferred embodiment of the suction pad according to the present invention will be described in detail below with reference to the accompanying drawings.

In FIGS. 1 and 2, reference numeral 10 indicates a suction pad according to this embodiment. This suction pad 10
A cylindrical root portion 12 having a hole portion 11, a skirt portion 14 integrally connected to the root portion 12, and further the root portion 12
It is composed of a plurality of ribs 16 bulgingly formed on the outer peripheral surface, here, three ribs offset by 120 ° on the outer periphery. Preferably, the suction pad 10 is integrally formed of a highly flexible synthetic resin.

Reference numeral 20 indicates a lock ring attached to the suction pad 10. The lock ring 20 has a groove portion 22 with which the rib 16 is engaged, on the inner peripheral surface thereof. In addition, the root part 12
An adapter 30 defining a passage communicating with a vacuum suction source (not shown) is fitted into the hole 11 of the.

The suction pad 10 and the lock ring 20 according to the present embodiment
Is configured as described above. Next, its operation and effect will be described.

First, in the work transfer device, the suction pad 10 having an appropriate shape and size is selected from the shape and size of the work.

Next, the lock ring 20 is attached to the adapter 30 of the vacuum suction device.
And the adapter 30 is fitted into the hole 11 of the root part 12. Then, attach the lock ring 20 to the rib 16 on the outer peripheral surface of the root portion 12.
Is forced to fit into the root portion 12. As a result, the rib 16 is formed inside the groove 22 of the lock ring 20.
And the lock ring 20 is attached to the suction pad 10. That is, the lock ring 20 strongly presses the outer peripheral surface of the adapter 30 to integrate them.

Next, the suction pad 10 is attached to an arm of a robot, and the skirt portion 14 is moved by displacing the arm.
The end portion of the workpiece comes into contact with the work, and the work is sucked and conveyed under the reduced pressure inside the skirt portion 14. Also, the shape,
When exchanging the suction pad 10 to accommodate different size works, the suction pad 10 can be easily removed from the adapter 30 by forcibly pulling out the lock ring 20 of the suction pad 10 from the rib 16 of the root part 12. Can be pulled out.

Therefore, the suction pad 10 can be attached and detached in a short time, and the work as a whole can be efficiently performed.

[Advantage of the Invention] As described above, according to the present invention, the suction pad suitable for the shape and size of the work can be easily selected and replaced.

As a result, it is possible to obtain the unique effect of shortening the time for exchanging the suction pad.
