Description

Detailed Description of the Invention Technical Field This invention relates to a full bobbin insertion device into a peg used for discharging a full bobbin placed on a conveyor means from the conveyor means and conveying it to the next process. .

Conventional technology In recent years, as part of rationalization of roving machines,
In order to improve operating efficiency, there is a remarkable trend toward higher speeds and larger packages, and with this, streamlining the work of replacing tubes after full tubes and discharging full bobbins has become an urgent issue. In other words, manually handling full bobbins in large packages is not only extremely labor-intensive for workers, 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 the conventional full bobbin discharge device,
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, which has the disadvantage that the rovings are easily damaged. The work of removing the products from the transport vehicle had to be done manually, which was a factor that hindered the automation of the next process.

In addition, in order to eliminate the above-mentioned drawbacks, a conveyor rail is arranged under the ceiling beam of the factory, and full bobbins discharged from the conveyor means by a full bobbin automatic discharge device are suspended on a conveyance 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 time. Therefore, it is necessary to always keep a stock of full bobbins unloaded from the roving frame, and in addition to the transport route from the conveyor means to the spinning machine, a large number of conveyor rails must be installed to store the full bobbins, which increases equipment costs. It has the disadvantage of being bulky.

Therefore, in order to solve these problems, the inventors invented a new full bobbin conveying device that transfers the full bobbin unloaded from the roving machine onto a peg for conveying the roving to the next process without damaging the roving. did.

Purpose An object of the present invention is to use the above-mentioned novel device to suspend a full bobbin discharged from a conveyor means and to securely insert the full bobbin into a peg on a conveying means for conveying it to the next process.
