The beam 14 is used for winding the warp 4 unwound from each bobbin 2 of the creel 1, and the beam 14 is driven by a driving device to rotate.

The mechanism for fixing the length of the remained tail of the warping machine beam comprises a remained tail detection device 15 arranged on the bobbin creel 1, a remained tail conveying device 100 arranged between a fixed-width reed 10 and a beam 14, a remained tail cutting device 200 arranged between a lease reed 9 and the fixed-width reed 10 and a control system 300 for controlling the devices and the operation of controllable parts of the warping machine. As shown in fig. 2, the control system 300 is in signal connection with the left tail detection device 15, the left tail conveying device 100, the left tail cutoff device 200, and the respective driving devices of the warping machine.

The tail detection device 15 is used to detect the warp threads 4 unwound from the respective bobbin 2 and to send a signal to the control system 300 when the unwinding of the first warp thread 4 is detected. The tailing detecting device 15 comprises a plurality of detecting sensors 151, each detecting sensor 151 is respectively arranged at a corresponding yarn guide porcelain eye 3, when the detecting sensor 151 detects that no warp thread 4 passes through the corresponding yarn guide porcelain eye 3, a signal is fed back to the control system 300, the control system 300 controls the driving device of the driving shaft 14 to stop working according to the received signal, and the driving shaft 14 stops rotating.

The control system 300 can also control the tail conveying device 100 and the tail cutting device 200 to work respectively based on the signals fed back by the tail detection device 15.

As shown in fig. 3, the tailing conveyor 100 includes a roller 19 capable of moving up and down, and a plurality of guide roller groups 18 arranged on the front and rear sides of the roller 19. The roller 19 is in signal connection with a control system 300, and the control system 300 can control the lifting of the roller 19; the roller 19 can contact the warp thread 4 during the lifting and lowering, and continuously feed the warp thread 4 to the weaving shaft 14 with the guide roller groups 18 on both the front and rear sides.

In this example, each guide roller group 18 includes an upper guide roller 181 and a lower guide roller 182 which are arranged opposite to each other in the up-down direction, and the warp thread 4 can pass between the upper guide roller 181 and the lower guide roller 182; the upper godet roll 181 has only the function of relatively fixing the position of the warp yarn, and thus, the upper godet roll can be omitted in other embodiments; and the lower godet 182 is disposed to be movable up and down with respect to the body of the warping machine, and the tension of the warp passing through the lower godet 182 can be adjusted during the up and down movement of the lower godet 182. In this example, a tension spring 184 is provided below each lower godet 182, and by adjusting the tension spring 184, the lower godet 182 can be moved up and down to adjust the tension of the warp threads 4. Of course, in the embodiment, the guide roller group can be integrally installed on a mounting frame capable of moving up and down, and the guide roller group can be moved up and down by moving the mounting frame.

In order to detect the tension of the warp threads 4 pulled by the roller 19, several tension detectors 183 are also arranged in the mechanism of the present case.

The tail-remaining cutting device 200 comprises a controllable lifting platform 16 and a cutting knife 17 arranged on the lifting platform 16. The lifting platform 16 is positioned below the moving path of the warp thread 4, and when the control system 300 receives a signal fed back by the tail-remaining detection device 15, the lifting platform 16 is lifted to provide a bearing effect for the conveying of the warp thread 4. The cutting knife 17 is used to cut the warp threads 4 carried on the lifting platform 16 in order to achieve the same length of the warp threads 4 wound on the beam 14.

The warping machine further comprises a glass guide rod 5, a rear reed 6, a warping godet roller 7 and a warp stop sheet 8, wherein the glass guide rod 5, the rear reed 6, the warping godet roller 7 and the warp stop sheet 9 are arranged between the creel 1 and the leasing reed 9. The plurality of warps 4 on the creel 1 are arranged in the same plane in the width direction by the above components. A large roller 12 and a beam guide roller 13 are also arranged between the beam 14 and the tail-remaining conveying device 100, and the large roller 12 and the beam guide roller 13 are used for enabling the warp threads 4 to be uniformly arranged on the beam 14 and have uniform tension.

When the warping machine works, the warp 4 is unwound from the bobbin creel 1, and under the active winding action of the driving beam 14, each device between the bobbin creel 1 and the driving beam 14 warps 4; when the warp thread 4 on a certain bobbin 2 is unwound first and is finished, the detecting sensor 151 arranged near the bobbin 2 detects that no warp thread 4 passes through the corresponding yarn guide porcelain eye 3, and the detecting sensor 151 feeds back a signal to the control system 300. After receiving the signal, the control system 300 controls the driving devices of the large roller 12 and the beam 14 of the warping machine to stop driving, controls the roller 19 to move downwards at a constant speed through an instruction signal, and controls the lifting platform 16 to move upwards at a constant speed; when the descending roller 19 contacts with the warp 4 and descends to a certain height, the control system 300 sends a signal to the tail retaining and cutting device 200, the cutting knife 17 moves downwards after receiving the signal to cut off the tail retaining warp 4 in order, and then the cutting knife 17 ascends and resets; the roller 19 moves upwards after the tail-remaining warp threads 4 are cut off, meanwhile, the control system 300 drives the driving shaft 14 and the large roller 12 to rotate slowly, the driving shaft 14 winds the tail-remaining warp threads 4 with fixed length, and the tail-remaining warp threads 4 with fixed length are fixed through a width-fixing adhesive tape.

In addition, during the process of conveying the warp thread 4 by the roller 19 and the guide roller group 18 of the tailing conveyor 100, the tension detector 183 located at the lower guide roller 182 monitors the tension of the warp thread 4 contacting the lower guide roller 182 in real time, and the tension detector 183 feeds back the detected tension signal to the control system 300 in real time. The control system 300 can adjust the tension of the warp thread 4 by adjusting the tension spring 184 to move the guide roller group 18 up and down; in this way, the warp threads 4 can be conveyed in a uniform manner by means of the tail conveyor 100 and the warping process.

The invention provides a method for fixing the length of the beam stay of a warping machine, which adopts the mechanism for fixing the length of the beam stay of the warping machine, and as shown in figure 4, the method comprises the following steps:

b. controlling the driving shaft 14 of the warping machine to stop rotating and simultaneously utilizing the tail remaining conveying device 100 to continuously pull the warp 4 to move towards the driving shaft 14 based on the signal of the step a;

c. all the warp threads 4 passing through the lease reed 9 are cut at the same position by the tail retaining and cutting device 200, and then the beam 14 is driven to rotate again, so that the tail parts of the cut warp threads 4 are wound on the beam 14 according to the set requirements.

The setting requirement in the step c includes a warp yarn tension requirement, the tension detector 183 is used for detecting the tension of the warp yarn 4 at the tail remaining conveying device 100, the tension requirement and the real-time tension data detected by the tension detector 183 are compared through the control system 300, and the tension spring 184 is controlled to move the lower godet roller 182 when the real-time tension does not meet the requirement according to the comparison result, so that the tension in the winding process of the weaving beam 14 is adjusted.
