Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a peripheral surface of a warping drum in which various yarns are drawn out from a rotary creel that rotates in synchronization with a yarn guide by a rotating yarn guide and held with torsional rigidity. And is fed onto a conveyor belt that is arranged in parallel with the axis of the warping drum,
A method for producing a warp yarn for a handle, in which unnecessary yarns are temporarily excluded from the warping process, and a warp drum held with torsional rigidity, and a warp drum disposed on a peripheral surface of the warp drum. It has a conveyor belt that runs parallel to the axis of the warping drum, a rotary creel, and a support for a yarn guide that rotates in synchronization with the rotary creel, and the yarn guide pulls the yarn from the rotary creel. The present invention relates to a pattern warp partial warping machine capable of feeding a yarn onto a conveyor belt and temporarily taking out individual yarns from the warping process.

[0002]

This prior art is known from DE 198 45 245 C1. In this prior art, many different patterns can be produced in a relatively short time by temporarily excluding individual threads from the warping process. Threads that are temporarily not needed are connected to their thread guides by tightening and cut between the tightening point and the warp drum, and when needed again, the free thread ends of the threads are held fixed and tightened. By removing the attachment, the yarn is taken out.

An object of the present invention is to enable partial warping of a pattern warp yarn by a method different from the conventional method.

[0004]

According to the present invention, which is a method, the above-mentioned object is provided on an auxiliary carrier which is arranged in the region of the axis of the warp drum until the yarn not needed is used again. It is solved by being wound up and unloaded by this auxiliary transport device, which is carried out in the direction of the side of the warping drum remote from the rotary creel at an average speed which is approximately the same as the average speed of the transport belt.

In the case of this method, the cutting device and the tightening device are
There is no need to assign it to each thread guide. Rather, the yarn, which is temporarily not needed, is wound on the auxiliary conveyor, which moves parallel to the conveyor belt, rather than on the conveyor belt. In this way, the yarn on the auxiliary transport device can be reintroduced into the warping process by simply changing the yarn feed. The overall productive and simple method is obtained.

Preferably, a wire is used as the auxiliary carrier. As a result, the yarn layer of the yarn that is not needed can be made very small, thus reducing the amount of waste produced by the yarn.

In particular, a wire-shaped or rope-shaped plastic wire can be used as the auxiliary carrier. Such filaments, for example made of nylon, can be discarded together with the yarn material which is not needed.

With respect to the device (partial warper), according to the invention, a yarn guide device is provided for each yarn, the yarn guide device comprising at least one yarn which is fed onto a conveyor belt. In addition to the active work position (effective work position), there is a non-active work position (rest work position) in which unnecessary yarn is guided into the gap between the support of the yarn guide and the conveyor belt,
An axially drivable auxiliary conveying device is arranged in the region of the warp drum axis, and the auxiliary conveying device is provided with a structure for forming an unnecessary yarn core.

According to this partial warper, it is possible to select either one of the winding of the yarn on the conveyor belt and the winding of the yarn on the auxiliary conveyor by simply operating the yarn guide device. You can This results in a very simple structure.

Preferably, the auxiliary conveying device comprises a storage roll located on the side of the rotary creel away from the warp drum and a pulling drive device located at the end of the warp drum on the side away from the warp creel. It is that it has been extended over. The drive device keeps the auxiliary carrier tensioned and continuously moves the auxiliary carrier in the warping direction at a desired speed.

Desirably, the drive speed of the auxiliary carrier is
On average, it is equal to the drive speed of the conveyor belt.
According to this structure, the slanted yarn path that obstructs the winding process is not required.

In the case where the auxiliary transporting device is made of wire or plastic wire-shaped or rope-shaped wire,
When the friction brake is provided on the inlet side, the auxiliary transport device can be sufficiently tensioned by the drive device.

Desirably, a waste container is provided at a stage subsequent to the driving device of the auxiliary transporting device.

A particularly advantageous design is such that the thread guide is adjustably mounted on the support and is movable by the control device into at least one of the active and inactive working positions. is there. In such a configuration, the yarn guide, together with the main components, is simply displaced in the direction of the warp drum axis,
The yarn guide functions as a yarn guide device that pushes down unnecessary yarn during the warping process. The thread guide still has other functions, such as the construction of a conical thread layer in the case of multi-layer winding, and / or
Alternatively, it is also possible to produce a wound layer of the same type and the same density, even though the yarn is taken out from the warping process.

The yarn guide is carried by a lever, and the lever is rotatably mounted on an arm that rotates around the warp drum axis, which is a desirable design. A lever that can be swung continuously or stepwise by a motor makes it possible to position the attached thread guide in the desired working position each time.

The warping drum has at least one lateral wall, which lateral wall has a radially extending slot, which surrounds the auxiliary conveying device at a distance and which is open at the peripheral surface of the lateral wall. And having this end bridging the distance between the cutting rod and the lead rod following the cutting rod in the direction of rotation of the support of the thread guide is also an interesting and preferred configuration. This radially extending slot ensures that when the yarn is to be reintroduced into the warping process, it will be returned onto the conveyor belt,
It makes it possible to cut threads that were temporarily excluded from the warping process together with the threads that were actually warped.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the drawings.

The partial warp machine for handle warp shown in FIGS. 1 to 4 has a warp drum 1. On the circumferential surface of the warp drum 1, a conveyor belt 2 extending parallel to the axis of the warp drum 1 and arranged parallel to the axis of the warp drum 1 so as to move in the direction of arrow 3 in FIG. Dividing rod 4,
5 and 6 are arranged. The dividing rods 4, 5, 6 can also be called lead rods or cutting rods, depending on their respective action. Rotating creel 7
Has a rotating body 8, and as shown in FIG. 3, this rotating body 8 carries a large number of bobbins 9, and the rotary creel 7 is driven by a motor 10 to drive a belt transmission 11 and a hollow shaft 12 Driven through.

A support 15 provided with a thread guide 14 is configured to move in synchronization with the creel 7 by another hollow shaft 13. The support 15 has a plurality of radially extending arms 17 held by a hub 16 and a lever 18 at each outer diameter end of the arms 17.
Is pivotally attached. As shown in FIG. 4, these levers 18 are configured so that they can be swung by a stepping motor 19 which can be operated by a control device 20. As a result, the yarn guide 14 provided at the tip of the lever 18 can occupy various working positions when passing by the side of the conveyor belt 2. Three of these work positions are shown in FIG. 3 with the line types shown changed. At the active work positions (effective work positions) a and b during the warping process, the yarn guide 14 draws the yarn 21 from the warp creel 7 and feeds it onto the conveyor belt 2 (see the active work positions a and b). In this way, one or more warp yarn layers 22 are obtained. In the working position c, the yarn guide 14 is inactive (resting state) during the warping process, that is, in a non-acting position, and the yarn guide 14 carries the unnecessary yarn 21 ′ to the conveyor belt 2 and the support 1 of the yarn guide 14.
5 into the gap 23 between them (inactive working position c), their threads 21 'do not participate in the warping process.

An auxiliary conveying device 24 in the form of a wire-shaped monofilament plastic filament extends along the axis of the warping drum 1. This auxiliary conveying device 24
Is a storage roll 25 that is inserted through the hollow shafts 12 and 13 and that is located on the side of the rotary creel 7 that is remote from the warp drum, and a tension drive device 26 that is located on the side of the warp drum 1 that is remote from the rotary creel 7. Has been extended between. The auxiliary transport device 24 is provided with the "unnecessary yarn 21 '" guided into the gap 23 by the yarn guide 14 at the inactive working position c.
Function as a winding core. As a result, the unwanted yarn 21 ′ forms a yarn layer 27 on the auxiliary transport device 24. The drive device 26 uses the auxiliary transport device 24 and the transport belt 2
In synchronism with the movement of (1), the warping drum 1 is moved in the end direction (the left end side in FIG. 3) located on the side away from the rotary creel 7. As a result, the individual thread layers 27
Can reach the drive 26 and be collected in a waste container 28.

By simply displacing the thread guide 14 into the inactive working position c, the thread 21 is excluded from the warping process as a thread 21 '. By displacing the thread guide 14 into the active working position a or b, the warping process is started again. In order to prevent the yarn 21 ′ moving between the auxiliary transport device 24 and the warp drum peripheral surface from interfering with the axial movement of the auxiliary transport device 24, as shown in FIG.
The lateral wall 29 of the warping drum 1 is provided with slots 30 extending in the radial direction, and these slots 30 are used for the auxiliary transport device 24.
Has a distal end 31 which surrounds and is open to the peripheral surface of the lateral wall 29. This end 31 is connected to the dividing rod (cutting rod) 4 and the lead rod 5 following the dividing rod (cutting rod) 4 in the rotation direction 32 of the support 15 of the thread guide 14 (see the rotation direction of arrow 32 in FIG. 2). Bridge the distance between. Therefore, the unnecessary yarn 21 'is cut together with the warped yarn.

The auxiliary transport device 24 should have a diameter which is as small as possible so that only a small amount of debris from the yarn layer 27 remains. In this embodiment, the diameter of the auxiliary conveying device 24 can be suppressed to less than 10 mm, particularly 6 to 7 mm by using a monofilament-shaped plastic filament.

The embodiments described above can be modified and implemented in various points without departing from the basic idea of the present invention. For example, the motor 19 can be operated steplessly or stepwise in the entire working position. Instead of two active work positions a, b, it is also possible to provide only one or more than two active work positions. The auxiliary transport device 24 may have other configurations, for example, a configuration having a cross section different from the circular cross section.
