Description

[Detailed explanation of the invention] This invention is suitable for the next process such as warping, doubling, and twisting the yarn of the yarn package cage (pipe yarn, cheese, pern, etc.) for unwinding. This relates to a winder for rewinding.

In conventional winders of this kind, each winding unit is equipped with a stop device, a thread breakage detector and a length measuring device, and when the thread breakage detector of each winding unit detects thread breakage, the thread breakage is detected. The stopping device of only the winding unit that caused the problem will operate and stop winding the yarn in that winding unit, and the number of stops due to thread breakage during the winding operation in each winding unit will be uneven. Even if the winding unit is equipped with a measuring device, the actual winding amount of the thread-wound woodwind in each winding unit will be uneven due to the length measurement error of the length measuring device due to the stoppage of the winding operation in each winding unit. There was a problem that there was a lot of wasted thread in the post-process. Furthermore, as mentioned above, each winding unit is equipped with a length measuring device, and this length measuring device is relatively expensive, so if you try to increase productivity by increasing the number of winding units, the overall Another problem was that the manufacturing cost was extremely high.

Therefore, the purpose of the present invention is to solve the above-mentioned problems of the conventional device.Even if the frequency of thread breakage in each winding unit varies, it is possible to make the amount of winding of the winding woodwind in each winding unit approximately equal, and to make it possible to To provide a winder in which the number of length measuring devices can be reduced even when the number of winding units is increased, and the cost can be reduced accordingly.

It is composed of rods 27 and 28. Note that this tension device 20 may be configured with another tension device such as a gate type, or one of the first and second tension devices 23 and 26 may be replaced with a well-known waxing device as needed to apply wax to the thread. You can do it like this. 29 is the above receiving plate 2
1 is formed as a thread guide portion, 30 is a support body 19;

When the yarn breakage detectors 46 of each of the winding units _A1 to _Ao detect the operating portion 47b, that is, the occurrence of yarn breakage, they send a signal to the stop device 49 of the drive shaft 31 to immediately stop the rotation of the drive motor 60. It's starting to stop. The above-mentioned stop device 49 is constituted by a contact point or the like that stops energization to the drive motor 60. The stopping device 49 is composed of a clutch provided between the drive motor 60 and the drive shaft 31 and a switch for engaging and disengaging the clutch. The rotation may be stopped. next,

Reference numeral 1 denotes a well-known winding meter 5 which is a length measuring device attached to a mounting bracket 50 and measures the length of the passed thread by counting the number of revolutions of a length measuring pulley 52.
It is composed of 3. This length measuring device 51 is installed only in one winding unit _A1 .
Note that the length measuring pulley 52 can also be used to measure the yarn length by interlocking with the drive shaft 31 or other rotating body that has a constant relationship with the yarn length. 54 is the winding meter 5 mentioned above.

In the case of the above structure, when rewinding the yarn, first, before starting the operation of the device, the yarn packages 9 for rewinding are attached to the pegs 8 of each winding unit _A1 to _Ao , respectively, and Wooden tubes 38 for winding threads are rotatably attached to the cradles 36 of each of the winding units A1 _{to Ao} , and the outer peripheral surfaces of the wooden tubes 38 are brought into pressure contact with the outer peripheral surface of the winding drum 33, respectively. next,
After the yarn a pulled out from each of the yarn package cages 9 is hooked onto the yarn guides 16, 17 and the guide section 29, the receiving plates 2 of the first and second tension devices 23, 26
1 and 24 and the weights 22 and 25, and then passed through the slit 30a of the clearer 30, and then passed through the upper side of the guide rod 28 and the lower side of the hook part 47a of the detection rod 47, and then wound up. It is guided between the drum 33 and the woodwind 38. In the above case, in one winding unit _A1 , the thread guide 16,
The thread a hooked on the thread 17 is passed between the clamping plates 56 and 56 of the tension device 55, then wound around the length measuring pulley 52 of the winding meter 53, and then the thread a is pulled on the guide portion 29. Multiply. Further, the setting value of the winding meter 53 is set to a value corresponding to the desired amount of thread winding on the woodwind 38. Next, the start button of the control box 59 is pressed to rotate the drive motor 60. The drive shaft 31 is rotated in the direction of the arrow by the rotational drive of the drive motor 60, and the winding drums 33 of each winding unit _A1 to _Ao are simultaneously rotated integrally, and each woodwind 38 is rotated with respect to the winding drum 33. Rotate in the opposite direction. As a result, the thread a is pulled out from each thread package 9 and wound around the outer periphery of the woodwind 38 while being traversed. When the yarn a is wound around the woodwind 38 by the rotation of the winding drum 33 in this way, the clearer 30 of each winding unit A ₁ to _{A o}
Tension is applied to the thread a guided between the winding drum 33 and the winding drum 33, causing the thread a to become taut, causing the thread a to pull up the hook 47a of the thread breakage detector 46 as shown in FIG. Move the operating section 47b away from the proximity switch 48. Therefore, thread breakage detector 46
The proximity switch 48 does not detect the operating portion 47b, and the drive motor 60 continues to rotate. Note that when the drive motor 60 is started by operating the start button, the clearer 30
Since there is no tension in the thread a between the winding drum 33 and the winding drum 33, the hook part 47a of the detection rod 47 descends and the operating part 4
7b is raised and the proximity switch 48 is activated, but when the drive motor 60 is driven by operating this start button, the proximity switch 48 is configured so as not to stop driving the drive motor 60. be. The drive motor 60 is rotationally driven as described above, and the woodwinds 38 of each winding unit _A1 to _Ao are rotated.
When yarn a is wound up in each winding unit A ₁ ~
Since all the winding drums 33 of A _o are rotated as one,
The yarn a is wound around the wood tubes 38 of each of the winding units A ₁ to _{A o} at the same speed, and approximately the same amount of yarn is wound around each of the wood tubes 38 . Next, as described above, the drive motor 6
0 is being driven to wind the thread a onto the woodwind 38 in each of the winding units _A1 to _Ao .
When the thread a being wound in any of the winding units breaks, the hook part 47a of the detection rod 47 in that winding unit descends under its own weight, and the operating part 47b of the detection rod 47 is moved to the upper plate 5b. Raise it until it touches the. Therefore, the proximity switch 48 is actuated by its operating portion 47b to detect the yarn breakage, and the proximity switch 48 thereby sends a signal to the stop device 49 to stop the driving of the drive motor 60. Therefore, the winding drums 33 of each winding unit A ₁ to _{A o} are stopped at once, and each winding unit is
The winding of the thread a onto the woodwind 38 at A ₁ to _{A o} is simultaneously stopped. After that, the yarn is spliced in the winding unit where the yarn breakage occurred, and then the start button is operated again to drive the drive motor 60, thereby simultaneously winding the yarn a onto the woodwind 38 in each of the winding units _A1 to _Ao. Start. As mentioned above, when a yarn breakage occurs in any winding unit, the winding operation of yarn a in all winding units A ₁ to A _o is stopped immediately,
After that, all the winding units A ₁ to A _o start winding the yarn a at the same time, so each winding unit
Even if the number of thread breakages at A ₁ to A _o is uneven, the woodwind 3 wound at each winding unit A ₁ to _{A o}
The amount of thread winding in case No. 8 is approximately equal. When winding the thread in each of the winding units A ₁ to A _o as described above, the winding meter 53 in the winding unit A ₁ is connected to the winding meter 53 in the winding unit A ₁
8. Measure the length of the thread a wound around the thread a. and,
When the measured value of the winding meter 53 reaches a preset value, the winding meter 53 sends a signal to the stop device 49 to stop the drive motor 60, and the winding meters 38 in each winding unit _A1 to _Ao are stopped. Complete winding of thread a. In this case, the amount of thread wound on the thread-wound woodwind 38 wound by each of the winding units A ₁ to A _o is approximately equal to the set value. Thereafter, the cradle 36 is swung against the biasing force of the weight 45 to be separated from the winding drum 33, and in this state, the thread-wound woodwind 38 is removed from the cradle 36.

Next, in the case of the above structure, when designing this, the winding operation of the yarn a in each winding unit A ₁ to A _o is stopped in one stroke by stopping the drive shaft 31 as described above. Therefore, there is no need to provide a stop position for the winding operation for each winding unit A ₁ to _{A o} as in the conventional device, and the structure can be simplified accordingly. Furthermore, as described above, the winding work of the yarn a in each of the winding units A ₁ to _{A o} is performed simultaneously, so that even if there are many winding units, at least one of the length measuring devices 51 can be used. Only one winding unit needs to be provided with the winder, and the cost of the entire winder can be significantly reduced.

As described above, this invention includes a peg for holding the thread package for unwinding, a wood pipe support device for supporting the wood pipe for winding up, and a wood pipe supported by the wood pipe support device. A winding drum for rotation and a winding unit having a yarn path for guiding the yarn of the yarn package to the outer periphery of the winding drum are arranged in parallel, and these winding units are operated in parallel. Therefore, by operating each winding unit in parallel, it is possible to pull out the thread from each unwinding thread package of each winding unit and wind the thread onto each woodwind. Woodwinds can be wound up, increasing productivity.

In addition, each winding unit is equipped with a thread breakage detector capable of detecting thread breakage in the thread moving along the thread path, and one of these thread breakage detectors is activated to detect thread breakage. Then, a signal is immediately sent to the stop position to stop the rotation of the drive shaft, and the rotation of the winding drums of each winding unit is stopped at once, so the winding drums of each winding unit are rotated at the same time. When winding thread onto a woodwind, even if thread breaks occur unevenly in each winding unit, the thread winding operations on the woodwind in each winding unit can all be synchronized, and this allows each winding unit to wind the thread. The amount of thread winding (winding length of thread) of the thread-wound woodwind can be made approximately equal, and a large number of homogeneous thread-wound woodwinds can be formed at the same time. Therefore, in the subsequent process, it is possible to reduce the amount of yarn remaining due to unevenness in the amount of winding of the thread-wound woodwind, thereby reducing waste of thread.

Furthermore, as described above, the amount of thread wound on the winding woodwind in each winding unit can be made approximately equal, and at least one of each winding unit is equipped with a length measuring device capable of measuring the length of the thread wound on the winding winding. As a result, the winding amount of the thread-wound woodwind in each winding unit can be set to an arbitrary length corresponding to the subsequent process, and there is an advantage that it can easily accommodate cases where the winding amount of the thread-wound woodwind varies.

Furthermore, even if the length of the thread-wound woodwind in each winding unit can be measured by a length measuring device as described above, the winding amount of the thread-wound woodwind in each winding unit can be made approximately equal. Since the number of winding units equipped with the length measuring device described above can be reduced to at least one, the number of relatively expensive length measuring devices can be reduced, and the overall manufacturing cost can be reduced.
