Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a device for inserting a full bobbin into a truck peg, which is used when discharging a full bobbin placed on a conveyor means from the conveyor means.

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. Not only is it extremely hard work for the operator to manually handle full bobbins in large packages, but it also increases the time it takes to do the work, reducing the efficiency of the roving machine. I will let you do it. 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 insertion 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, so the roving is easily damaged. In addition, 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 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 a spinning factory, 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. 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 stock the full bobbins, which increases equipment costs. It has the disadvantage of being bulky.

In order to solve these problems, the inventors invented a new full bobbin unloading device that transfers the full bobbin unloaded from the roving frame onto a cart to be transported to the next process without damaging the roving yarn. did.

OBJECT The object of the invention is to use the above novel device,
