[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0029] The up and down directions described in the present invention refer to Figure 1 The up and down directions in .
[0030] The present invention will be further described below in conjunction with the accompanying drawings.
[0031] like Figure 1-3As shown, the warp yarn replacement system provided by the present invention comprises: a first rotating shaft 10, a second rotating shaft 20, a yarn taking device 40, and a yarn filling device 50, wherein the first rotating shaft 10 is rotatably arranged, and its two ends can be fixed on the support surface by bearing seats and the like, the second rotating shaft 20 has the same structure as the first rotating shaft 10, and the second rotating shaft 20 can also be rotatably arranged, the first rotating shaft 10 and the second rotating shaft 20 are both air expansion shafts, the first rotating shaft 10 is fitted and tightened with a warp yarn roll 100, the second rotating shaft 20 is fitted and tightened with a reel 200, and the reel 200 is connected to the first rotating shaft 10. The reel structure in the warp roll 100 is the same, the second rotating shaft 20 is arranged parallel to the first rotating shaft 10 and spaced apart, the yarn on the warp roll 100 is wound onto the reel 200 in sequence, and a gauze net 30 is formed between the warp roll 100 and the reel 200, the winding means that the yarn is pulled out from the warp roll 100 and fixed to the reel 200, and the sequence means that the yarn is arranged on the reel 200 in sequence; the yarn taking device 40 is located below the gauze net 30, and the yarn taking device 40 includes a guide roller 401 and a rotatable yarn taking roller 402. The yarn that needs to be replaced is guided by the guide roller 401 and then wound onto the yarn taking roller 402; the yarn filling device 50 is also located below the yarn mesh 30 and is spaced apart from the yarn taking device 40 so as not to interfere with the operation. The yarn filling device 50 includes a tension wheel 501 and a rotatable yarn filling roller 502. The yarn on the yarn filling roller 502 is wound onto the reel 200 after passing through the tension wheel 501; when the warp reel yarn replacement system is in operation, the speed at which the warp reel 100 and the yarn filling roller 502 release the yarn is equal to the speed at which the reel 200 and the yarn taking roller 402 take up the yarn. Specifically, the warp yarn replacement system also includes a detector for real-time detection of the diameters of the warp yarn roll 100, the fill yarn roller 502, the reel 200, and the yarn taking roller 402, and a control mechanism for controlling the rotational speeds of the first rotating shaft 10, the second rotating shaft 20, the fill yarn roller 502, and the yarn taking roller 402. The control mechanism adjusts the rotational speeds of the first rotating shaft 10, the second rotating shaft 20, the fill yarn roller 502, and the yarn taking roller 402 according to the detection value of the detector, so that the speed at which the warp yarn roll 100 and the fill yarn roller 502 release the yarn is equal to the speed at which the reel 200 and the yarn taking roller 402 take up the yarn.
[0032] The yarn taking roller 402 has a certain length in its axial direction. Preferably, the length of the yarn taking roller 402 is equal to the length of the warp yarn roll 100, so that multiple yarns to be replaced in the yarn net 30 can be taken out at the same time, and the structure of the yarn taking device 40 is simple, without the need to set up too many yarn guiding devices.
[0033] In order to evenly arrange the yarn taken out from the yarn net 30 on the yarn taking roller 402 and prevent it from accumulating in a certain area of the yarn taking roller 402, the yarn taking device 40 also includes a wire arrangement wheel 403, which can move along the axial direction of the yarn taking roller 402. The wire arrangement wheel 403 is located between the guide roller 401 and the yarn taking roller 402. When the yarn taking roller 402 reels the yarn, the wire arrangement wheel 403 moves at a uniform speed along the axial direction of the yarn taking roller 402, so that the yarn passing through the wire arrangement wheel 403 is evenly arranged on the yarn taking roller 402. Of course, when taking out multiple yarns from the yarn net at the same time, multiple wire arrangement wheels 403 are required.
[0034] In this embodiment, the tension wheel 501 is a self-weight tension wheel, and the tension wheel 501 includes a main shaft 5012 and a body 5011 rotatably mounted on the main shaft 5012. Specifically, a bearing 5013 is mounted on the main shaft 5012, and the body 5011 is mounted on the bearing 5013. The body 5011 can rotate relative to the main shaft 5012. The main shaft 5012 can be movably mounted on the bracket 503 of the yarn filling device 50. The hanging counterweight can adjust the weight of the tension wheel 501 itself, thereby adjusting the tension of the yarn wound on the reel 200 after passing through the tension wheel 501. The body 5011 is disc-shaped, and an annular groove 5014 is provided on the outer circumference of the body 5011. The cross section of the annular groove 5014 is V-shaped, and the notch width of the annular groove 5014 is smaller than the thickness of the body 5011. The body 5011 is made of insulating material, and a metal The metal sheet 5015 is annularly wrapped on the outer circumference of the body 5011. One side edge of the metal sheet 5015 is flush with the groove wall of the annular groove 5014 or slightly exceeds the groove wall. The thickness of the metal sheet 5015 is 0.5-0.8mm. The metal sheet 5015 is electrically connected to the outer ring of the bearing 5013. The main shaft 5012 is connected with a high-voltage power supply 70, which is transmitted to the metal sheet 5015 through the main shaft 5012 and the bearing 5013, so that the edge of the metal sheet 5015 close to the notch of the annular groove 5014 produces a discharge phenomenon, ionizes the air at the notch, and when the yarn is wound around the tension wheel 501, the static electricity on the yarn is removed. In order to improve the effect of ionizing the air at the notch, the edge of the metal sheet 5015 close to the notch is serrated. Of course, in order to avoid the yarn from hitting the sawtooth and causing a short line, a guide wheel can be used to guide the yarn to the side close to the center of the annular groove 5014.
[0035] Since the reel 200 becomes a new warp roll after winding the yarn, in order to make the new warp roll consistent with the winding direction of the yarn on the warp roll 100, the first rotating shaft 10 and the second rotating shaft 20 are respectively located on the upper and lower sides of the yarn mesh 30, and the first rotating shaft 10 and the second rotating shaft 20 rotate in opposite directions.
[0036] The present invention also provides a method for replacing warp yarn rolls, comprising: winding the yarns of the warp yarn rolls onto the drums one by one, so that the warp yarn rolls are parallel to and spaced apart from the drums to form a yarn net, drawing out the yarns that need to be replaced from the yarn net and winding them onto a yarn taking roller, and then winding the yarns on the yarn filling roller onto the corresponding positions on the drums for replenishment, and rotating the warp yarn rolls, the drums, the yarn taking rollers and the yarn filling rollers at the same time to transfer the yarns on the warp yarn rolls to the drums to form new warp yarn rolls. During the transfer process, the yarns are replaced, and the warp yarn rolls, the drums, the yarn taking rollers and the yarn filling rollers release or take up the yarns at equal speeds.
[0037] Preferably, when the yarn is drawn out from the yarn net and wound on the yarn taking roller, the yarn is arranged on the yarn taking roller in sequence by a wire arrangement wheel; when the yarn is wound from the yarn filling roller onto the reel, the yarn tension is adjusted by a tension wheel and static electricity on the yarn is eliminated.
[0038] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:
[0039] The warp roll yarn replacement system provided by the present invention can take out the yarn from the warp roll without manual drawing of the yarn, and can also add the replaced yarn to the corresponding position, which saves time and labor and is highly efficient. The warp roll yarn replacement method provided by the present invention is simple, convenient and easy to promote.
[0040] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
