ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to the removal of residual yarn from the yarn tube, and more particularly to a device, and a method of using the device to remove residual yarn from the yarn tube.
BACKGROUND OF THE INVENTION
The conventional way of removing the residual yarn from the yarn tube involves the use of a cutter by an operator to separate manually the residual yarn from the yarn tube. Such a conventional way as described above is primitive at best. The surface of the yarn tube is susceptible to damage caused inadvertently by the operator in the course of cutting off the residual yarn. In addition, such a manual operation of stripping the residual yarn from the yarn tube is not cost-effective. Moreover, the dust of the yarn residue, especially the dust of the yarn of glass fiber, is a potential health hazard to the worker.
The residual yarn is generally recycled for making an instrument panel, a safety helmet, and the like. It is likely that a residual yarn is contaminated with the metal impurities in the course of the manual removal of the residual yarn. The residual yarn of a low purity is of a little value as far as the recycling of the residual yarn is concerned.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an automated device for removing the residual yarn from the yarn tube economically and efficiently. The automated device of the present invention eliminates the shortcomings of the conventional manual operation of removing the residual yarn from the yarn tube.
The automated device of the present invention comprises a feeding mechanism, an index dial, a residual yarn removing mechanism, a suction mechanism, and an arranging mechanism. The feeding mechanism of the present invention is designed to take in simultaneously a plurality of yarn tubes with residual yarn attached thereto. The index dial is provided with a plurality of clamping tools for holding the yarn tubes horizontally to facilitate the removing of the residual yarn from the yarn tube by the residual yarn removing mechanism. The yarn residue is removed by the suction mechanism. The stripped yarn tubes are arranged uprightly by the arranging mechanism for storage or transportation.
The feeding mechanism of the automated device of the present invention comprises a rotary tray, and a first mechanical arm. The rotary tray is used to receive the incoming yarn tubes, which are then transferred by the first mechanical arm to the clamping tools of the index dial. The arranging mechanism comprises a second mechanical arm and a conveyor. The stripped yarn tubes are arranged uprightly by the second mechanical arm before they are carried away by the conveyor.
