Yarn winding equipment

Abstract

The present invention provides a yarn winding apparatus including a plurality of winding units, a tray conveying device having an individual path and a first discharge path, a bobbin processing device having a second discharge path, and a control unit. The pallet conveying device has a first conveyor mechanism that conveys the pallets on the first discharge path. The bobbin processing apparatus has a second conveyor mechanism that conveys the trays on the second discharge path. The first conveyor mechanism and the second conveyor mechanism are driven by separate drive sources, respectively. The yarn winding device further includes: a tray detection unit that detects the tray on the second discharge path; and a determination unit that determines whether the tray remains on the second discharge path based on the detection result of the tray detection unit. When the determination unit determines that the tray remains on the second discharge path, the control unit stops the operation of the first conveyor mechanism while operating the second conveyor mechanism.

Description

technical field [0001] The present invention relates to a yarn winding device. Background technique [0002] The yarn winding apparatus disclosed in Japanese Patent Laid-Open No. 2011-20837 includes a plurality of winding units, a bobbin preparation device (hereinafter referred to as a bobbin processing device), and a pallet conveying device. Each winding unit unwinds the yarn wound on the pre-supply bobbin and winds it on the winding bobbin. The bobbin processing device performs preparation of pre-supply bobbins to be supplied to a plurality of winding units, residual yarn removal processing of pre-supply bobbins (hereinafter referred to as discharge bobbins) discharged from the plurality of winding units, and the like. The pallet conveying device conveys the pallet (yarn feeding pallet) on which the pre-supply bobbin is mounted and the pallet (discharge pallet) on which the discharge bobbin is mounted, and transfers the pallets between the bobbin handling device and the p...

AI Technical Summary

Problems solved by technology

In this way, for example, the following problem is likely to occur, that is, in the vicinity of the point where the separate path and the discharge path merge, the discharge tray conveyed on the separate path and the discharge tray conveyed on the discharge path are pressed against each other and cannot move ( bridge plug phenomenon)

In such a case, the discharge tray cannot be conveyed to the bobbin processing device side, and the processing efficiency of the bobbin processing device can be reduced.

In addition, if the discharge path is congested, the tray cannot move from the individual path to the discharge path, and the individual path is blocked, the tray cannot be discharged from the winding unit, and there is a possibility that the processing of the winding unit will stop.

[0007] In addition, even with the configuration in which the bypass path as described above is provided in the pallet conveyance device, if the discharge trays are congested on the discharge path, there will be problems such as blockage of the discharge tray at the confluence position where the discharge path and the bypass path merge.
