Problems solved by technology

[0002] The existing doffing work is mainly divided into manual doffing and doffer doffing. The manual doffing step is to cut the tail yarn first and insert the empty tube, which is inefficient and prone to end breaks. The doffing steps of the ring spinning frame are generally as follows: 1. Unplug the full bobbin from the spindle bar of the spinning frame; 2. Disconnect the yarn connecting the full bobbin and the spindle bar; Plug in the spindle bar, then start the spinning frame and start the next round of spinning work
At this time, the disconnected yarn is in an uncontrolled state. After the spinning frame is turned on, the spindle rotates rapidly, and the yarn is more likely to be thrown off, and the phenomenon of end breakage will occur, which requires manual inspection and wiring. Repeated, increase labor cost, delay production efficiency

Embodiment 1

[0021] The doffing process that the present invention is used for ring spinning doffer comprises:

[0022] Step 1: pull out the full yarn bobbin 5 from the spindle bar 6 through the tube pulling device 2 on the doffing machine 1, and at this time, the yarn 8 between the spindle bar 6 and the full yarn bobbin 5 is in a connected state,

[0023] Step 2: Open the bottom of the empty bobbin box 32 of the intubation device 3 on the doffing machine 1, and start the bobbin stirring device at the bottom of the empty bobbin box 32, so that the empty bobbin 7 falls into the insertion hole of the intubation device 3. pipe channel 33,

[0024] Step 3: Place the empty bobbin 7 on the spindle bar 6 of the spinning frame 9 through the intubation manipulator 35 of the intubation device 3 on the doffing frame 1. At this time, the connected yarn between the full bobbin 5 and the spindle bar 6 Line 8 is held down,

[0025] Step 4: Disconnect the yarn 8 connected between the spindle bar and the...

Embodiment 2

[0030] Such as figure 1 As shown, the automatic doffing machine that uses the steps of the above method includes a tube pulling device 2, a tube insertion device 3 and a yarn breaking device 4, and the tube pulling device 2 is a Cartesian robot, and the structure and work of the Cartesian robot For the process, refer to the invention of an automatic control device for a doffing machine in my country, the publication number is CN102634891A, the Cartesian coordinate robot is arranged above the doffer 1, and several extruding manipulators 21 are arranged on the Cartesian coordinate robot. An intubation device 3 is provided above the Cartesian robot, and a yarn breaking device 4 is provided below the Cartesian robot near the side of the spinning frame 9 .

[0031] The intubation device 3 includes a support 31, an empty bobbin box 32, a bobbin channel 33, a square column 34 and several intubation manipulators 35, and the support 31 is fixedly welded on the bed body of the doffing mac...

Abstract

The invention discloses a doffing process used for a ring-spinning doffer, relates to a doffing process of the doffer used for a ring-spinning spinning frame, and provides a doffing method of the doffer. According to the doffing method of the doffer, the labor cost can be reduced, and the production efficiency can be improved. The doffing process used for the ring-spinning doffer includes the steps of pulling a full bobbin away from a spindle blade through a bobbin pulling device on the doffer under the adjustment and control of a control system, then inserting an empty bobbin into the spindle blade of the spinning frame in a sleeved mode through a bobbin inserting device on the doffer, cutting off yarns connected between the spindle blade and the full bobbin through a yarn cutting device on the doffer, finally placing the full bobbin into the doffer through the bobbin pulling device on the doffer, in this way, repeating the motions, and achieving the aim that the empty bobbin is firstly inserted and then the yarns are cut. The production efficiency is accordingly improved.

Description

technical field [0001] The invention relates to a working method of a doffing device in the textile industry, in particular to a working method of a doffer for a ring spinning frame. Background technique [0002] The existing doffing work is mainly divided into manual doffing and doffer doffing. The manual doffing step is to cut the tail yarn first and insert the empty tube, which is inefficient and prone to end breakage. The doffing steps of the ring spinning frame are generally as follows: 1. Unplug the full bobbin from the spindle bar of the spinning frame; 2. Disconnect the yarn connecting the full bobbin and the spindle bar; Plug in the spindle bar, and then start the spinning frame to start the next round of spinning. At this time, the disconnected yarn is in an uncontrolled state. After the spinning frame is turned on, the spindle rotates rapidly, and the yarn is more likely to be thrown off, and the phenomenon of end breakage will occur, which requires manual inspec...
