Abstract

PURPOSE:To shorten the standstill time of a splicing dolly and perform splicing and taking-up quickly and certainly by making the rotation of a friction roller identical to the yarn takeup speed when slack yarn does not exist in front of a sensor in the middle part of a slack tube, and putting the splicing dolly in traveling when it does not exist in front of a sensor at the foremost opening. CONSTITUTION:When a slack yarn Y' does not exist in front of a sensor 38 in the middle part of a slack tube 36, the sensor 38 issues a signal to restitute an arm rod of an acceleration roller 31, and a ring-shaped drum and a motor are stopped rotating. Because a rotary shaft, meantime, continues rotating at the takeup speed, clutch between the rotary shaft and ring-shaped drum is engaged, and ring-shaped drum of a friction roller 20 is rotated associate with rotation of the rotary shaft. Thus the slack yarn Y' in the slack tube 36 will pass in front of another sensor 37 at the foremost opening. Because the slack yarn Y' will no more exist in front of this sensor 37, it is now practicable for a yarn splicing dolly 8 to move to the next operating position in conformity to the signal given by the sensor 37.

に悪影響を及ぼすことがあった。[Prior Art] In a spinning machine, yarn is spliced using a yarn splicing cart when yarn is cut, but during this time the yarn continues to be spun from the spinning section, resulting in slack. is suctioned and held in a suction pipe called a slack tube. However, when yarn is spun at high speeds such as 200 m/min or higher, the length of slack in the yarn during splicing becomes long, and especially when extra time is required for splicing, slack tuning may occur due to timing discrepancies in various parts of the spinning machine. -The slack thread sucked into the slack tube is
It passes through the inside of the tube and reaches the suction main pipe connected to the slack tube, increasing the tension of the yarn on the spinning side, making it impossible to spin, or causing the yarn to crack. Sometimes it gets caught up in the package and has a negative impact on the quality of the yarn.

As a result, an increase in the number of parts and costs could not be avoided. Therefore, it was considered to install a slack tube on the yarn splicing cart, but the yarn splicing cart could not run unless the yarn was pulled out from the slack tube, and as a result, the slack yarn in the slack tube was rapidly removed. It was necessary to pull it out of the tube.

As shown in FIGS. 4 and 5, the roller 31 includes an arm rod 40 that swings with the rotation of the rotating shaft 39, a motor 41 attached to the tip of the arm rod 40, and a pulley on the motor shaft. The signals emitted from the sensor 37 are sent to the movement circuit of the yarn splicing cart 8, and the signals emitted from the knotter and sensor 38 are sent to the swing circuit of the acceleration roller 31 and the on/off circuit of the motor 41. Connected to off-circuit.

moves and stops at the weight, and the suction pipe 34,
By operating the suction mouth 35 and the knotter, the upper and lower yarns are spliced and normal operation is resumed.

However, when a timing difference occurs in each part of the spinning machine, such as when continuous high-speed spinning from the spinning section 2 or extra time is required for yarn splicing, the amount of slack yarn Y' gradually increases. traverses sensor 38 to reach the base of slack tube 36.

The pulley 32 of the acceleration roller 31 starts rotating at a higher speed than the peripheral speed of the annular drum 26, and the arm rod 40 swings, causing the high speed rotating pulley 32 to rotate at a higher speed than the circumferential speed of the annular drum 26. 26 surface, the clutch between the rotating shaft 22 and the annular drum 26 is disengaged, and the annular drum 26 is brought into contact with the rotating shaft 2.

As it rotates, the slack yarn Y' in the slack tube 36 eventually passes through the front surface of the sensor 37, and as a result, the slack yarn Y' no longer exists in front of the sensor 37, and the signal emitted from the sensor 37 causes the yarn to The trolley can now be moved to the next operating position.

If the circumferential speed of the friction roller 20 by the acceleration roller 31 is about 400 m/min, the time required to carry out the present invention is only about 2 to 5 seconds, and furthermore, if the spinning speed is 500 m/min. It has become clear that the above cases can be adequately handled.

A slack tube that sucks and holds the slack part of the yarn being spliced, and an acceleration roller that contacts the surface of the friction roller and rotates the roller at high speed are mounted on the yarn splicing cart, and the yarn splicing cart is equipped with Acceleration roller and friction roller just before
The slack yarn in the slack tube is pulled out by rotating the friction roller at high speed, and when there is no slack yarn in front of the sensor in the middle of the slack tube, the acceleration roller The rotation of the friction roller is made to match the winding speed of the yarn, and the sensor at the end opening of the slack tube starts the yarn splicing cart when there is no slack yarn in front of it. Since the yarn is moved, by temporarily increasing the speed of the friction roller, the slack yarn that is spun at high speed and sucked into the slack tube even after the yarn is cut can be rapidly reduced, and the yarn can be spun at high speed. This makes it possible to resume splicing and winding of the spun yarn, and unlike the conventional method, the slack yarn in the slack tube reaches the main suction pipe connected to the slack tube, increasing the tension of the yarn on the spinning side. , it becomes impossible to spin, or the yarn becomes flapped, and the generated flutter is wound into the winding package even after the yarn is spliced, and does not have a negative effect on the quality of the yarn. One blower is installed in each unit of the spinning section, and in order to suction all the slack tubes on the spinning machine table with one blower, a large suction force and installation space are required, resulting in an increase in the number of parts and costs. However, in the present invention, the slack tube is mounted on the yarn splicing trolley, and the suction blower for suction mouth can be used in common with the suction mouth, reducing suction power and installation space. - We were able to solve the problem of space, reduce the number of parts, and lower costs.
