Abstract

A disc grabbing device including a body, a drive shaft, a first cam, a second cam, multiple first movable parts and multiple second movable parts are provided. The drive shaft is rotatably disposed in the body. A first cam and a second cam are disposed on the drive shaft, and rotate together with the drive shaft. The first movable parts are disposed in the body and correspond to the first cam, and move to a disc hold position or a disc release position along with the rotation of the first cam. The second movable parts are disposed in the body and correspond to the second cam, and move to a disc release position or a disc hold position along with the rotation of the second cam.

Claims10

Dependent claims

A disc grabbing device used for grabbing a plurality of discs and sequentially unloading the discs, the disc grabbing device comprising:

a body;
a drive shaft rotatably disposed in the body;
a first cam and a second cam disposed on the drive shaft, wherein the first cam and the second cam are rotated together with the drive shaft;
a plurality of first movable parts disposed in the body and corresponding to the first cam, wherein the first movable parts move to a disc hold position or a disc release position along with a rotation of the first cam;
and
a plurality of second movable parts disposed in the body and corresponding to the second cam, wherein the second movable parts move to the disc release position or the disc hold position along with a rotation of the second cam;
wherein the disc grabbing device has a first operating state in which the first movable parts and the second movable parts are located at the disc release positions;
wherein the disc grabbing device has a second operating state in which the first movable parts are located at the disc hold position and the second movable parts are located at the disc release position;
wherein the disc grabbing device has a third operating state in which the first movable parts are located at the disc release position and the second movable parts are located at the disc hold position.

6 more elements

An operating method of a disc grabbing device comprising a drive shaft, a first cam and a second cam disposed on the drive shaft, a plurality of first movable parts corresponding to the first cam, and a plurality of second movable parts corresponding to the second cam, the operating method comprising steps of:

when the disc grabbing device intends to grab a plurality of discs,
driving the first cam and the second cam to rotate by the drive shaft, such that the disc grabbing device enters a first operating state in which the first movable parts and the second movable parts are located at a disc release position;
driving the first cam and the second cam to rotate by the drive shaft, such that the disc grabbing device enters a second operating state to complete the operation of grabbing the discs, wherein in the second operating state, the first movable parts are located at a disc hold position, and the second movable parts are located at the disc release position;
when the disc grabbing device intends to unload one of the grabbed discs,
driving the first cam and the second cam to rotate by the drive shaft, such that the disc grabbing device enters a third operating state in which the first movable parts are located at the disc release position, and the second movable parts are located at the disc hold position;
and
driving the first cam and the second cam to rotate by the drive shaft, such that the disc grabbing device enters the second operating state to complete the operation of disc unloading.
