Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a two-stage type yarn feeding package which allows a double twister processing robot to easily perform yarn end ejection processing and the like.

[Prior Art] A double twister winds a yarn drawn from a yarn feeding package supported by a spindle through a shaft hole thereof to form a double twist and winds it around a paper tube supported by a cradle arm. To form a package. When the paper core winds up all the yarns in the yarn supply package and becomes a full winding package, replace the empty yarn supply package with a full yarn supply package (feed replacement) Pull the thread end (out) and pass it through the shaft hole (thread thread),
It is necessary to remove the winding package full of balls from the cradle arm, support a new paper core on the cradle arm (deep lifting), and fix the yarn end drawn from the yarn supply package to the paper core (thread hooking). .

Conventionally, these operations have been performed by humans, which is troublesome.

However, in the present day when the frequency of operations such as doffing and yarn feeding has increased with the production of a large variety of small quantities, automation of the above operations has been desired in order to reduce labor and improve productivity. Therefore, the applicant of the present invention has a double twister processing robot capable of automatically changing the yarn feeding package, tapping, threading, doffing, and thread hooking, thereby reducing labor and improving productivity. Filed (Japanese Patent Application No. 1-63857
issue).

[Problems to be solved by the invention] By the way, a double twister uses a two-stage type yarn supply package in which yarn supply packages are arranged in upper and lower two stages, and the yarns from both yarn supply packages are double twisted while being combined. Some have done so. In such a double twister, the yarn ends drawn from the upper and lower yarn supplying packages must be collectively ejected so that the yarn can be threaded through the shaft hole.

However, it is extremely difficult to configure the processing robot so as to pull out the yarn ends from the upper and lower yarn supplying packages and to expose the yarn ends in a combined state.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to solve the above problems and provide a two-stage type yarn supplying package that can easily discharge the upper and lower yarn ends together by a double twister processing robot.

[Means for Solving the Problems] In order to achieve the above object, the present invention inserts the yarns from both yarn feeding packages into the adapter at the upper end of a cylindrical adapter that fits and supports the yarn feeding package in two upper and lower stages. A top cap for guiding is integrally formed, and both thread ends are wound around the top cap.

[Operation] Since the yarn ends of the upper and lower yarn supplying packages are wound around the top cap in a pre-assembled state, in the processing robot, for example, a suction mouth capped on the top cap only sucks both yarn ends. Thus, the yarn ends can be easily pulled out in a state where both yarn ends are gathered together, and the next yarn threading process becomes easy.

[Embodiment] An embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

In FIG. 1, reference numerals 1 and 2 denote yarn feeding packages obtained by winding a yarn around a core tube 3, and these yarn feeding packages 1 and 2 are fitted on the outer periphery of a cylindrical adapter 4 in a vertically stacked two-stage manner.

When the swivel arm 18 swivels to move from the standby position to the exit position, the suction mouth 22 descends and is capped on the upper end of the top cap 9, and the wound portion B of the yarn end is pulled out and unraveled by the suction action. The yarn ends Y1 and Y2 are sucked into the suction cylinder pair 20 through the connecting pipe 23 and the suction arm 21. Thread ends Y1, Y2 of upper and lower yarn feeding packages 1, 2
Are wound around the top cap 9 in a pre-assembled state, so that the upper and lower yarn ends can be easily squeezed out in a collected state by the suction action of the suction mouth 22. Whether or not the spouting is successful is detected by the sensor 25. When the spouting is successful, the suction mouth 22 is raised and returned to the standby position, and then the swivel arm 18 returns the two-stage yarn feeding package 5 from the spout position to the standby position. In the case of a lead-out error, the package 5 is simply mounted on the spindle as it is, and the presence of the lead-out error package is displayed in the unit without performing subsequent operations. Then, the operator performs rework processing. Alternatively, an alarm may be issued or the two-stage yarn feeding package 5 may be returned to the conveyor 13.

During the feeding process, the empty two-stage yarn feeding package on the spindle is transferred onto the tray of the conveyor 13 by moving up and down the operation arm 16 and operating the chucker 34. In this case, since the two-stage yarn feeding package 5 on the outlet peg 14 is located at the outlet position apart from the operation arm 16, the operation arm 16 does not interfere with the two-stage yarn feeding package 5 and the feeding process can be performed. The discharge processing of the empty two-stage yarn supply package can be performed in parallel.

Next, the yarn pulling arm 26 reciprocally pivots from the standby position to the operating position and is hooked from the yarn feeding packages 1 and 2 of the two-stage yarn feeding package 5 to a middle portion of the yarn ends Y1 and Y2 connected to the suction mouth 22, The middle part of the yarn end is delivered to the yarn locking piece 36 of the chucker 34 standing by above the two-stage yarn supplying package 5. Then, the two-stage yarn feeding package 5 on the outlet peg 14 is moved and mounted on the spindle by raising and lowering the operation arm 16 and operating the chucker 34, and the yarn connecting between the yarn locking piece 36 and the suction mouth 22 is connected. The ends Y1 and Y2 are cut by the cutter 37, and threading is performed.
