Benefits of technology

[0013] The spindle sleeve or sleeve-like device is preferably made of plastic, or another polymer material which can be molded, and is light-weight and durable. Thus, the spindle sleeve or sleeve-like device is configured (in place of a spindle) for transporting a plurality of manufactured articles.

Problems solved by technology

Such spindles are typically made of a metal or alloy, and therefore the spindles can be relatively heavy and costly.
Further, mechanized movement of the spindles from one stage to another stage of an automated manufacturing line causes the spindle assembly to wear down rather quickly.
Therefore, substantial replacement costs are associated with use of spindles in an automated line.
Accordingly, spindle disengagement and transport requires operator attention and consumes operator time and energy.
In addition, operator disengagement and transport of the spindle also can cause wear to the spindle assembly.

Embodiment Construction

[0020] This disclosure provides tools such as a spindle sleeve or sleeve-like device configured to slip over a spindle for stacking a plurality of manufactured articles (for example, flat discs or cards, such as optical discs), in order to facilitate transport of the plurality of discs.

[0021] For example, in the manufacturing of optical discs, as discussed infra, discs are stacked on spindles at various stages of a manufacturing line. Conventional manufacturing systems use metal spindles which can manually be removed from the line. However, the metal spindles are rather costly, and therefore it is desirable to maintain a minimum number of spindles for use in the manufacturing system. For similar reasons, it is desirable to avoid using the spindles as transport devices.

[0022] Use of spindle sleeves or sleeve-like devices which slide over the spindles, as provided by this disclosure, allows the spindles to remain in place in the manufacturing system while allowing the spindle sleeve...

Abstract

A spindle sleeve configured to be placed over a spindle for holding a plurality of manufactured articles is provided. The spindle sleeve includes a hollow cylindrical body having a top end and an open bottom end and configured to slip over the spindle. An inner diameter of the cylindrical body is greater than an outer diameter of the spindle. The spindle sleeve may be used for stacking and transporting a plurality of optical discs. In such an instance, an outer diameter of the cylindrical body is smaller than a diameter of a center hole of the optical disc.

Description

TECHNICAL FIELD [0001] This patent disclosure relates to an apparatus for transporting articles which are normally stacked on a spindle in a manufacturing process. In particular, the disclosure relates to a sleeve-like device placed over the spindle onto which the articles are stacked. [0002] Such an apparatus or device may be used in the manufacturing of, for example, optical discs in which discs are typically accumulated on spindles at various stages of the manufacturing line. DESCRIPTION OF RELATED ART [0003] Use of optical discs, such as CDs (compact discs) and DVDs (digital versatile discs or digital video discs), as storage media for storing and transporting content (such as audio, video, graphics, computer software, etc.) in an optically readable manner has been popular for a number of years. Several formats of optical discs are currently available, including (A) read-only formats such as CD-DA (digital audio compact disc), CD-ROM (CD-read-only memory), DVD-ROM, and other for...
