Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jewel case lid opening device for opening a jewel case lid.

[0002]

2. Description of the Related Art A plastic jewel case is generally used for storing an optical disk such as a CD. The jewel case includes a bottom portion to which the optical disc is fixed when stored, and a lid portion that covers the upper surface of the bottom portion. The lid is attached to the bottom so as to be capable of rotational movement about one end as a rotation axis, and the opening and closing operation of the lid is performed by this rotational movement. When the lid is closed, the lid is mechanically fitted with the bottom, so that the closed state of the lid can be maintained.

[0003] When the optical disk manufactured in the manufacturing process of the optical disk is stored in the jewel case, the storing process is generally performed by a mechanized automatic storage device. When storing an optical disk in a jewel case, it is necessary to first perform an opening operation to open the lid of the jewel case.
First, the vacuum pad is vacuum-sucked to the bottom surface and the lid surface of the jewel case, and then, while fixing the bottom of the jewel case, the lid portion is pulled up by the power of a power source such as a cylinder, thereby forming the jewel case. The lid was being opened.

[0004]

However, the jewel case has a difference in lid fitting strength depending on molding conditions of a molding die, a jewel case manufacturing company, and the like. This appears as a difference in the initial lid opening required force, which is a force required in the initial stage of the operation. And
If the required initial lid opening force changes between lots, etc., and the required initial lid opening force exceeds the suction force of the vacuum pad on the bottom surface and lid surface of the jewel case, the jewel case comes off from the vacuum pad. In addition, there is a problem that a lid opening trouble such as insufficient initial lid opening force occurs.

[0005] Even if the initial lid opening force does not change, the suction force of the jewel case may be reduced due to the aging of the vacuum pad or the like, and a similar lid opening trouble may occur.

Further, since the operation of opening the lid of the jewel case is performed using the driving force of a power source such as a cylinder, the driving force of the power source such as a failure or aging of the power source such as a cylinder is determined. Is smaller than the initial lid opening required force, there is also a problem that a lid opening trouble occurs as described above.

The present invention has been made in view of the above points, and provides a jewel case lid opening apparatus capable of reducing a trouble of opening the jewel case lid in a storage step of storing an optical disk or the like in a jewel case. The purpose is to do.
