Automatic drop tube control system for adjusting quantity of operation box tubes of spinning frame

Abstract

The invention relates to an automatic drop tube control system for adjusting quantity of operation box tubes of a spinning frame. The automatic drop tube control system comprises a bobbin counting sensor, a full yarn lifting device, an operation box and a PLC (Programmable Logic Controller), wherein the bobbin counting sensor is arranged on the full yarn lifting device and is used for acquiring data of the quantity of bobbins; the full yarn lifting device is connected with the PLC by virtue of a communication line and is used for conveying full yarn tubes into the operation box by virtue of aconveyor belt; the operation box is arranged just under a lifting outlet of the full yarn lifting device and is used for receiving the full yarn tubes lifted by the full yarn lifting device; the PLC is connected with the bobbin counting sensor by virtue of a communication line and is used for receiving acquired data transmitted by the bobbin counting sensor; a man-machine interface is connected with the PLC by virtue of a communication line. According to the automatic drop tube control system disclosed by the invention, the quantity of drop tubes can be optionally changed according to requirements under the condition that the cost is extremely low, so that the operation box is full each time. Moreover, stained spindles caused by overloading of bobbins as well as blocking and damage of machine parts can be avoided.

Description

technical field [0001] The invention belongs to the technical field of spinning frames, and in particular relates to an automatic control system for tube drop of a spinning frame for adjusting the number of tubes in a running box. Background technique [0002] At present, during the spinning process of the traditional spinning frame, there is generally a running box that can load 240 spindles full of yarn as a unit to realize material transportation in different process workshops. However, the number of spinning frame spindles is far greater than the number of operating boxes, and the winding of some old models does not have the reception of large yarn warehouses. If a piece of yarn is spilled at the drop tube, it will not only affect the quality of the full yarn, but also often cause jams, resulting in damage to the conveying system. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a low-cost, high-efficiency, and all...

However, the number of spinning frame spindles is far greater than the number of operating boxes, and the winding of some old models does not have the reception of large yarn warehouses. A piece of spillage occurs at the drop pipe, which not only affects the quality of the full yarn, but also often causes jams, resulting in damage to the conveying system
