Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a transfer device for a yarn feeding package,
More specifically, the present invention relates to a transfer device for supplying yarn feeding packages to a two-stage yarn feeding type double yarn twisting machine.

[Conventional technology]

The package cages are stacked in two stages on the yarn feeder of the double twisting machine, the yarns are pulled out from both the upper and lower yarn feeder package cages, and the two yarns are passed through the spindle at the same time.
A machine that twists yarns while doubling them is called a two-stage yarn feeding type double twisting machine. Since the yarn is twisted while being doubled, the conventional yarn-combining process can be omitted, which has the advantage of labor saving and streamlining.

[Problem that the invention seeks to solve]

However, in the above-mentioned two-stage yarn feeding type double yarn twisting machine, the remaining yarn in the yarn feeding package becomes zero, and the task of replacing the yarn feeding package with a new yarn feeding package is very time-consuming. In other words, even when compared to a case where there is simply one yarn feeding package, the number of steps (labor) required for replacing the yarn feeding package is about twice as much.

[Means to solve the problem]

The transferred article is transferred on a conveyor extending along the double twisting machine, and the transferred article is placed between a tray having a convex portion erected in the center of a disc body, and inserted into the convex portion. The tray is made up of a guide pipe that is tubular and has an annular pawl integrally formed at its lowermost end, the guide pipe, and a plurality of yarn feeding packages that are inserted into and placed on the guide pipe, and the tray and the guide pipe , and a plurality of yarn feeding packages are conveyed as one body to a double yarn twisting machine, and at this position, the guide pipe supporting the plurality of yarn feeding packages is extracted from the tray and supplied to the double yarn twisting machine. This is what I did.

[Effect]

The yarn feeding packages are set in two stages in series on the guide pipe and transported to the double twisting machine, and then fed in the set state to the double twisting machine.

Further, a central cylindrical portion is integrally fixed onto the stationary plate 45, and the guide pipe 35 guide is inserted into the central cylindrical portion. 47 indicates a balloon guide, and 48 indicates a belt.

In FIG. 5, the actual yarn feeding tray 30a is circulating around the circulation line 16, and is forcibly stopped in front of the double yarn twisting machine 2, where yarn feeding packages Pa and Pb have been requested, and is automatically stopped by the automatic package changing machines 26 and 27. The actual yarn package placed on the tray 30a and the empty yarn package of the double twisting machine 2 are exchanged, and the empty yarn package is inserted onto the tray 30. The empty yarn feeding tray 30b exits the circulation line 16 and enters the exchange line 18. In the exchange line 18, the empty yarn package and the actual yarn package are exchanged by the yarn feeding exchange device 20, and the yarn ends of both yarn feeding packages Pa and Pb are transferred to the guide pipe 35 by the feeding device 21 as will be described in detail later. After being wrapped around the upper end of the yarn, the yarn is returned to the circulation line 16 as the actual yarn feeding tray 30a. The lower yarn supply package Pb and the upper yarn supply package Pa are alternately supplied to the yarn supply exchange device 20, and the upper and lower yarn supply packages are identified and supplied. Therefore, when the changing device 20 sequentially supplies the yarn feeding packages Pa and Pb, the lower yarn feeding package Pb is connected to the upper yarn feeding package Pa on the lower side.
are respectively placed on the upper side.

In other words, in order to eliminate the waste of remaining yarn in the lower yarn feeding package due to the difference in unwinding tension between the upper and lower yarn feeding package, the yarn amount of the lower yarn feeding package Pb is set smaller than that of the upper yarn feeding package Pa. -ing

Next, the configuration of the pick-out device 21 will be explained based on FIG. 1. Upper and lower yarn feeding package PA,
A suction pipe 51 with an opening 50 in the shape of a flap is installed on the side of Pb. The suction pipe 51
A guide bar 53 that moves up and down about a fulcrum 52 is located between the opening 50 and the yarn supply packages Pa and Pb.
is installed. That is, the guide bar 53 is attached to the tip of the link 55 slidably inserted into the shaft 54.
is fixed, and a protrusion 56 between the guide bar 53 and the shaft 54 is slidably fitted into a groove 57.
The shaft 54 is connected to a drive member (not shown) via a link 58. On the other hand, scissors 59 are installed at the upper end of the suction tube 51, and a thread Y is driven by a drive device (not shown) via a link 60.
It is now possible to cut the

Furthermore, at the installation position of the pick-up device 21, one side of the frame 40 is cut out, and the roller 62 can protrude into the frame 40 from the cutout 61 portion. The roller 62 is rotatably supported by a plate 63 and connected to a drive motor 64 so as to be rotatable.

With the feed device 21 having the above-described configuration, both yarn feeding packages Pa,
After suctioning the yarn ends Ya and Yb of Pb, the guide bar 53
to rise. Thereafter, the roller 62 is brought into contact with the side surface of the disc body 31 of the tray 30, and the roller 62 is rotated several times to rotate the tray 30 and the yarn supply packages Pa, Pb. After the yarn end that had been sucked into the suction tube 51 is lightly wrapped around the upper end of the guide pipe 35 several times, the scissors 5
9 cut the threads Ya and Yb. Note that whether or not the threads Ya and Yb are being sucked into the suction tube 51 can be determined by detecting the presence of the threads using an optical sensor or the like.

3 and 4 show the chuck 65 of the yarn feeding package changing device 20. This chuck 65 holds the guide pipe 35 into which the yarn feeding packages Pa, Pb are still inserted, and exchanges the actual yarn feeding package on the tray 30 with the empty yarn feeding package in the double yarn twisting machine 2. Rod 6 on base 66
7 is fixed, and a cap 68 is attached to the tip of the rod 67.
is fitted. The cap 68 and the base 6
A deformable ring body 69 made of an elastic member such as rubber is disposed between the rings 6 and 6.
and a tubular slider 70 are loosely fitted in this order. The slider 70 is always urged in the direction of an arrow 72 by a spring 71. Reference numeral 73 indicates a lever fixed to the slider 70.

With the above configuration, when the lever 73 is pulled upward 74 against the spring 71,
The chuck 65 is inserted from above the guide pipe 35. After insertion, when the upward force 74 of the lever 73 is released, the slider 70 is moved downward by the force of the spring 71, and the cap 68 and slider 70 press the deformable ring body 69 from above and below. Due to the pressing force, the deformable ring body 69 is deformed in a circumferentially outward direction and chucks the guide pipe 35 from inside. Since the inner side of the guide pipe 35 is chucked, there is no need to provide an extra length at the upper end of the guide pipe 35 for a portion to be gripped by the chuck. Therefore, the overall height of the guide pipe 35 can be kept low. The technical concept of stacking yarn feeding packages in two stages has the inherent problem that the overall height is high, which tends to cause problems in transportation, transfer, etc., but it is possible to reduce the height. is a huge advantage. Furthermore, the thread end is lightly wound around the upper end of the guide pipe 35, so that the inner chuck 65 does not have any influence on the thread end.

In the above embodiment, the yarn feeding package is transferred to the double yarn twisting machine in a state where it is placed in two stages,
Since it is fed to the double twisting machine as it is,
The labor of supplying the yarn is greatly simplified, and at the same time, it is possible to eliminate clumsiness such as when the upper and lower yarn feeding packages are reversed during yarn feeding.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the work of supplying the yarn feeding package to the two-stage yarn feeding type double twisting machine, that is, the work of replacing the empty paper tube and the yarn feeding package, can be easily performed. Moreover, even when the upper yarn supply package and the lower yarn supply package are supplied as different types of packages, the different types of packages do not coexist and can be reliably supplied. Furthermore, according to the present invention, a plurality of yarn feeding packages can be conveyed to the double yarn twisting machine while being inserted and placed on the tray, and can be replaced with empty paper tubes in the double yarn twisting machine, thereby enabling automatic conveyance and exchange. .
