Description

[Detailed Description of the Invention] [Industrial Application Field] When the present invention supplies pipe threads from a silk spinning machine to an automatic winder, in order to make it easier to take out the threads of the pipe threads in the automatic winder, Particularly concerning a conveyance system for automatically supplying Japanese-processed tube yarn, which has been pulled out and held through a large hole in a tube bobbin, to multiple automatic winders using a conveyance tray. A branch conveyance line consisting of a real tray and an empty tray conveyance rail is provided between the multiple yarn supply lines connected to the automatic winder, and a switching device is provided in the actual tray delivery section to switch from one tube yarn supply line to the other. The pipe system is configured to feed into the pipe supply line of the pipe.

[Prior Art] When feeding the pipe yarn wound up by a spinning machine to an automatic winder, the thread end (the thread) of the pipe thread is pulled out in advance in order to be able to easily pull out the thread end of the pipe thread in the automatic winder. This is then introduced into the large hole of the tube and yarn bobbin and held there. In addition, when supplying such a pipe yarn to an automatic winder, a tray having a base having a diameter larger than the outer diameter of the pipe yarn and having a pipe insertion bin protruding from the center of the base is used as a conveyance means. It is also well known that Furthermore, it has already been proposed that a drive belt with a round cross section be run inside the tray guide rail and the tray be carried while being placed on this drive belt as a means for transporting the tray.

The present applicant has previously developed an automatic winder equipped with a rotary magazine and a thread IA management device that uses such a conveying means to introduce and hold the threads of the threads lifted by the finishing machine into the large holes of the thread bobbin. We have developed and proposed a means of transporting and supplying pipe and line to automatic fishing equipment by connecting the two. However, these means only connect one pipe processing device and one automatic winder. However, with subsequent improvements, the processing capacity of this yarn processing device increased, and it was discovered that the treated yarn could be supplied to multiple automatic winders.

[Problems to be Solved by the Invention] However, with such a pipe yarn conveying and supplying means, it is necessary to return and supply the empty tray from which the pipe yarn has been removed to the pipe processing device again using this conveyance line. It is difficult to return the empty trays simply by distributing the tube-bearing trays (actual trays) taken out from the yarn processing device by providing branched guide rails. Furthermore, these conveying and branching rails must minimize the installation floor space and do not obstruct the operation of the automatic winder, and it is necessary to store the supply preparation pipe yarn in order to improve operational efficiency. be.

[Means for Solving the Problems] Therefore, the present invention connects the tray conveyance line to a yarn take-out conveyance line connected to the yarn processing device and a yarn supply line provided to the winder. It consists of a primary storage conveyance line, and a branch conveyance line connected to the pipe supply line of another automatic winder at the connection part, and each of these conveyance lines consists of a real tray conveyance rail and an empty tray conveyance rail. The tubes are connected to each other to form a secondary storage section for the tube and yarn in each of the tube and yarn supply lines, and a switching device is provided in the actual tray transfer section from the tube and yarn supply line to the branched conveyance line. be.
