Description

[Detailed description of the invention] This invention relates to a creel used for winding strings of cheese or corn onto the drum of a drum machine.

This type of creel is generally equipped with a large number of bobbin support rods for supporting cheese or corn in the creel body, and two bobbin support rods for guiding the cheese or corn thread corresponding to these bobbin support rods. Two yarn guiding portions are provided at intervals in the lateral direction, and a tensor is provided between each of the yarn guiding portions, which can apply tension to the yarn guided between the yarn guiding portions. However, in the case of conventional creels, the tensor stacks the required number of weight washers on the base plate, and uses the weight of the weight washers to sandwich the thread between the base board and apply tension to the thread. An adjusting plate having a guide post that is curved or protrudes upward on the base plate is rotatably mounted, and by changing the rotation angle of the adjusting plate with respect to the base plate, the guide post changes the path of the thread. Since tension is applied to the yarn, in the case of the former type, if you try to increase the yarn tension by increasing the number of weight washers, in the case of spun yarn, more fluff will occur, making it impractical for practical use. In the case of the latter, if you try to enlarge the thread path, the tensioner will become larger and it will be difficult to assemble it to the creel body, and in both cases, the range for adjusting the thread tension will become smaller, making it easier to use different threads. They cannot be used universally, and as a result, the types of thread that can be used are limited.In addition, both have the disadvantage that fluff accumulates on the weight washers and adjustment plates, and this fluff wraps around the yarn, causing the thread to break. It also had drawbacks such as inducing breakage. In addition, since the tensioner is constructed as described above, in order to obtain the necessary thread tension, the number of weight washers and the rotation angle of the adjustment plate for each tensioner must be adjusted manually based on past experience. There was a drawback that adjustments had to be made, and the adjustments required an extremely large amount of time and manpower.

Therefore, the present invention has been developed to eliminate the above-mentioned drawbacks, and the adjustment range of yarn tension can be made sufficiently large, making it possible to use it for various yarns (e.g., spun yarn, filament yarn, yarns of different thicknesses). It is also an object of the present invention to provide a creel in which the thread tension can be adjusted easily and in a short time, and the accumulation of fluff on the tensioner portion can be reduced.

In the case of the above structure, when winding a large number of cheese or corn threads onto the drum of a partial warping machine, for example, the movable frame 3 is supported by the fixed frame 2 by rotating the handle 15 by hand. Move the movable frame 3 to a position away from the frame 4 to form a large space between the movable frame 3 and the support frame 4 in which a person can fit, and in this state, place cheese or corn on each bobbin support rod 19 as shown in the imaginary line in FIG. Install as shown. Next, as shown in FIG. 3, the lifting rod 24 is lowered by its own weight, etc., and the first and second guide posts 28, 37 are positioned below the thread guide holes 22, 22, and the above-mentioned The cheese or corn threads are pulled out and conducted into the corresponding pair of thread guide holes 22, 22 of the movable frame 3. Next, after passing all the cheese or corn threads through the thread guide holes 22, 22 as described above, the handle 1
Movable frame 3 by rotating 5 again
is moved to a position close to the support frame 4, as shown in FIG. 2, and left at this position. Thereafter, each yarn passed through the yarn guide holes 22, 22 is further pulled out and guided by the yarn guide 60, and its tip is connected to a drum of a partial warper (not shown). Next, operate the operating device to rotate the rotating shaft 58a of the pulse motor 58 in the normal direction, move the horizontal moving rod 46 to the left in FIG. Raise it to the position where thread tension is applied. The ascending position of the elevating rod 24 is set in advance at a position obtained empirically. As the lifting rod 24 rises, the first and second guide posts 2 of the tensor 23
8 and 37, and for example, as shown in FIG. 7, only the first guide post 28 is raised to a position higher than the auxiliary post 40. As a result, the tensor 23 is moved between the yarn guide holes 22 and 2 between the yarn clamping bodies 33 and 34.
At the same time, the guide collar 30 of the first guide post 28 hooks the thread and pushes it up, and the thread is routed between the auxiliary post 40 and the first guide post 28 as shown in FIG. bend it into a chevron shape to increase the resistance applied to the thread. Therefore, it is possible to increase the thread tension acting on the thread when the thread is subsequently drawn out. After that, the drum of the partial warping machine is rotated to pass each yarn through the yarn guide holes 22 and 2.
Pull it out from 2 and start winding it onto the drum. Due to this yarn winding operation, a yarn tension of a magnitude suitable for winding the yarn is applied to the yarn extending from the tensor 23 to the drum by bending the yarn path by the tensor 23. In this case, if the yarn tension at that time is still smaller than the yarn tension of a size suitable for winding the yarn, the rotating shaft 5 of the pulse motor 58
8a is rotated in the normal direction to further raise the lifting rod 24, thereby increasing the degree of bending of the yarn path by the first guide post 28. This increases the resistance force applied to the yarn between the yarn guide holes 22, 22, making it possible to increase the yarn tension during yarn winding, and bringing the yarn tension closer to the yarn tension of a size suitable for the yarn at that time. be able to. Conversely, if the thread tension at that time is larger than the thread tension suitable for winding the thread, the rotating shaft 58a of the pulse motor 58 is reversed to lower the lifting rod 24 by its own weight, and the first guide post 2
8 to reduce the degree of bending of the yarn path. As a result, the resistance force applied to the yarn between the yarn guide holes 22, 22 is reduced, and the yarn tension during yarn winding can be reduced, and the yarn tension can be brought closer to a yarn tension of a size suitable for the yarn. be able to. The thread tension of each thread can be adjusted simultaneously by each tensioner 23 by rotating the pulse motor 58 in the forward and reverse directions and raising and lowering the lifting rod 24. The tension can be adjusted in a short time and with less effort, and can be easily adjusted even during the thread drawing operation. Further, by increasing the amount of elevation of the lifting rod 24, the range of adjustment of the thread tension can be easily increased. next,
If a yarn tension larger than the adjustment width of the yarn tension by the first guide post 28 of the tensor 23 is required depending on the type of yarn, yarn winding conditions, etc., the adjustment range may be as shown by the imaginary line in FIG. The lifting rod 24 is further raised to raise both the first and second guide posts 28 and 37 of the tensor 23 to a position higher than the auxiliary post 40. As a result, the first guide post 28 and the second guide post 37 are connected to the thread guiding hole 2.
The yarn between 2 and 22 is pushed up higher than the auxiliary post 40 to make the path of this yarn meander. As a result, the resistance force applied to the yarn when the yarn is wound becomes much larger than when the yarn path is bent only by the first guide post 28, and the yarn tension when the yarn is wound can be extremely increased. . 1st above,
Adjustment of the thread tension by the second guide posts 28, 37 can also be performed by raising and lowering the lifting rod 24, and the adjustment can be performed easily and quickly. Therefore, even when winding a variety of different threads, the tensioner 23 can easily apply thread tension suitable for winding the thread to the thread, thereby making it possible to wind the thread well on the drum. I can do it. Furthermore, the tension of the thread is adjusted by the tensor 23 by bending the thread path vertically using the first and second guide posts 28 and 37 that protrude laterally from the lifting rod 24. Even when the yarn to be drawn is a spun yarn, the generation of fluff when passing through the tensor 23 can be reduced, and a large amount of fluff can be prevented from accumulating on the first and second guide posts 28 and 37 of the tensor 23. It can be used not only for filament yarns but also for spun yarns without any problems.

In the above embodiment, the thread tension is adjusted by manually operating the pulse motor, but a sensor is provided to detect the thread tension, and the detected value of this sensor is fed back to the setting device to adjust the thread tension. This may be done automatically, and by doing so, the thread tension can be kept constant during thread winding. Further, although the elevator rod is raised and lowered by the rotation of the motor, it is also possible to raise and lower the elevator rod by rotating a manual handle or the like. Furthermore, the first and second guide posts of the above embodiment are located above the thread path, the auxiliary posts are located below the thread path, and the thread path is bent by lowering the lifting rod. Also good.

As described above, in the present invention, a tensor 23 is provided between each thread guide section 22, 22 for guiding the thread of cheese or corn, which can apply tension to the thread guided between the thread guide sections 22, 22. Therefore, when the threads of each cheese or corn are guided to the respective thread guide parts 22, 22 and wound around the drum, it is possible to increase the tension in each of these threads between the respective thread guide parts 22, 22. This allows each yarn to be wound well.

Further, the tensor 23 includes an elevating member 2 disposed on the creel main body 1 so as to be able to rise and fall by a predetermined amount on the side of the thread path of the thread guided between the thread guiding portions 22, 22.
4, and a plurality of guide posts 28, 37 provided on the elevating member 24 so as to protrude by a predetermined amount in the lateral direction so as to intersect with the yarn path when viewed in plan on either the upper or lower side of the yarn path. and at least one auxiliary post 40 provided on the creel body 1 on the other side of the upper and lower sides of the thread passage so as to protrude by a predetermined amount laterally so as to intersect with the needle thread passage when viewed in plan. , above guide post 2
The positions of the auxiliary posts 8 and 37 are set at intervals in the longitudinal direction of the yarn path, and the position of the auxiliary post 40 is set between the guide posts 28 and 37 when viewed in plan, and the guide posts 28 and 37 are set apart from each other in the longitudinal direction of the thread path. post 2
8, 37 and the auxiliary post 40, the yarn guide section 22,
Since the thread path between the thread guiding parts 22 is meandering to increase the thread tension, if you want to adjust the tension applied to the thread, you can raise and lower the elevating member 24 to increase the thread tension between the thread guiding parts 22, 22. By bending the thread path from a straight line to a meandering line, the thread tension can be changed significantly.This allows the range of adjustment of the thread tension to be increased, making it suitable for various types of threads such as spun threads and filament threads. It has the effect of being versatile for winding, and that the thread tension can be adjusted easily and in a short time simply by raising and lowering the elevating member 24.

Furthermore, even if the adjustment width of the thread tension can be increased as described above, the adjustment of the thread tension is performed from the guide posts 28 and 37 that protrude laterally from the elevating member 24 and from the creel body 1 in the lateral direction. This is done by making the thread path meander with the protruding auxiliary post 40, so the tensor 23
It is possible to reduce the occurrence of fluff in the tensioner section, reduce the accumulation of fluff, etc. on the tensor portion, and have the effect of preventing yarn breakage due to entanglement with fluff, etc.
