Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to eliminate troubles during thread replacement during warping using a fixed creel and a rotating creel together by moving a yarn guide to a yarn holding position or a yarn holding position. The invention relates to a sample warper and a movable yarn guide.

[0002]

2. Description of the Related Art A conventionally used electronically controlled sample warper is disclosed in, for example, Japanese Patent No. 1529104. That is, a plurality of bobbins wound with different kinds of yarns (different colors or different twists) are fixed. It is known to use a creel and wind a yarn on a warping drum by a yarn guide while exchanging a yarn with a yarn selecting device in accordance with preset pattern data (yarn order).

In addition, the use of a rotary creel and the elimination of the yarn changing step eliminates the time loss at the time of yarn changing, and allows a plurality of yarns to be wound around a warping drum at the same time. There is also known an electronically controlled sample warper capable of simultaneously warping a plurality of units, which enables shortening of the length (Japanese Patent No. 1767706, US Pat. No. 4,972,662 and E).
P0375480).

The fixed creel has a plurality of bobbins wound with the same kind and / or different kinds of yarns (mainly different kinds of yarns). Since the warping can be performed, there is an advantage that the warping operation of the pattern warping can be performed, but there is a disadvantage that the warping operation time is longer because one thread is sequentially wound around the warping drum. . On the other hand, the rotary creel has a plurality of bobbins wound with the same type and / or different types of yarns, and has a plain warping (for example, one color of red thread), one-to-one (for example, one red and one white). Repetition, one S twist and one Z twist), 2 to 2 (for example, two red and two white repeats,
It can be used for repetition (repetition) warping of a very limited pattern such as repetition of two S twists and two Z twists. This rotary creel has the disadvantage that it is not possible to perform pattern warping work other than limited pattern warping, but the warping time is greatly increased because multiple yarns are wound simultaneously on the warping drum. There is an advantage that it is shortened.

The applicant of the present application has disclosed a sample warper capable of extremely efficiently performing a warping operation requiring a solid warping and a pattern warping and shortening the warping time to a fixed creel and a rotating creel. Providing a plurality of corresponding yarn selection devices,
A sample warper combining pattern warping and iterative warping has already been proposed (Japanese Patent Application No. 11-9175, EP0933455).
A2).

In this sample warper, a fixed creel and a rotating creel are used alternately, and a plurality of yarns are exchanged by a yarn selecting device in a short time (for example, one rotation of a yarn guide). Troubles such as mischange and double winding are apt to occur. In the above-mentioned proposal, the yarn is removed from the yarn guide by rotating in a direction in which the yarn guide does not hold the yarn. In this case, the rotation of the yarn guide and the waiting time with the yarn selecting device change depending on the yarn type, yarn speed, and the like, so that there is a drawback that there are many yarn troubles at the time of yarn exchange.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and a new optimum mode has been set for the use mode of a yarn guide in a sample warping machine of the above-mentioned type, and the yarn replacement has been performed. A sample warper that can avoid the occurrence of trouble at the time of occurrence, shorten the warping time of the warping work that requires the plain warping and the pattern warping and can perform it extremely efficiently, and The purpose is to provide a yarn guide.

A guide, a yarn selecting device provided on a part of a base supporting the warping drum, for supplying yarn to these yarn guides and storing the yarn from the yarn guide, and a fixed creel and a rotating creel for erecting a plurality of bobbins. In accordance with a preset yarn order, the yarns from the fixed creel and the rotating creel are selectively exchanged while winding the yarn on the warping drum on a conveyor belt controlled to a predetermined feed amount while the yarn is wound. In a sample warper having a twilling mechanism to be formed, the plurality of yarn guides can be set in a state in which a yarn can be held and a state in which a yarn cannot be held.

As a yarn selecting device, for example, Japanese Patent Application Laid-Open
Using a yarn selection device equipped with a selection guide and a yarn removal guide as known in Japanese Patent No. 293536, only one yarn is selectively exchanged according to a preset yarn order, and the yarn is wound around a warping drum. In this case, it is more preferable that one of the plurality of yarn guides moves to the yarn holding position and the remaining yarn guides warp in a state where the yarn guides move to the yarn non-holding position.

[0010] When performing simultaneous warping of a plurality of yarns in accordance with a preset yarn order, it is preferable to perform warping while a plurality of yarn guides are moved to a yarn holding position.

In a preferred embodiment, one of the plurality of yarn guides is a fixed yarn guide, and the remaining yarn guides are movable yarn guides that can be moved between a yarn holding position and a yarn non-holding position. Become.

When only one yarn is selected and exchanged in accordance with a preset yarn order and the yarn is wound around a warping drum, the fixed yarn guide is used, and the remaining movable yarn guide is used for holding the yarn. If we were to warp in an impossible position,
More preferred.

When a plurality of yarns are warped simultaneously in accordance with a preset yarn order, if the remaining movable yarn guide is moved to the yarn holding position in addition to the fixed yarn guide, warping is performed. This is a more preferable embodiment.

The movable yarn guide of the present invention is characterized in that it can be moved to a yarn holding position and a yarn holding position by preferably using an air cylinder, a solenoid, a motor or the like.
