Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a method for unloading a full bobbin in a spinning machine and an apparatus therefor.

Conventional technology In recent years, there has been a remarkable trend toward higher speeds and larger packaging in order to improve operating efficiency as part of rationalization in roving machines.
Streamlining the process of discharging full bobbins became an urgent issue. That is, manually handling full bobbins in large packages is not only extremely labor intensive for the operator, but also significantly increases the time required for the work, reducing the operating efficiency of the roving frame. For this reason, automation of these operations has been desired, and various devices have been devised to achieve automatic discharge of full bobbins and automatic supply of empty bobbins.

However, in conventional full bobbin discharging devices, the full bobbins discharged from the conveyor means are stored in a transport vehicle in a horizontally stacked state and transported to the next process, making the rovings susceptible to damage. In addition to having drawbacks, in the next process, the work of taking out the full bobbin from the transport vehicle had to be carried out manually, which was a factor that hindered automation of the next process.

In addition, in order to eliminate the above-mentioned drawbacks, a conveyor rail is installed under the ceiling beam of the factory, and the full bobbins discharged from the conveyor means by the full bobbin automatic discharge device are suspended from the conveyor magazine suspended on the conveyor rail. A method has also been proposed in which the material is transported to the next spinning step. However, in spinning factories, the efficient operation of spinning machines plays a large role in improving productivity, so spinning machines are operated 24 hours a day or close to that. It is necessary to always keep bobbins in stock, and a large number of conveyor rails must be installed to serve as a 7-ton space for full bobbins on the conveyance route from the conveyor means to the spinning machine, which increases equipment costs. There are drawbacks.

Purpose This invention was made in order to eliminate the above-mentioned conventional defects, and its purpose is to transfer the full bobbin of the Isohei yarn onto a trolley for conveying it to the next process without damaging the roving. To provide a method and device for unloading a full bobbin in a spinning machine, which can be easily replaced and automated in the next process.
