Description

Detailed Description of the Invention [Industrial Field of Application] The present invention is directed to properly knotting a plurality of yarns for forming new warp yarns wound around a beam with corresponding yarns of warp yarns used in a loom. The present invention relates to a warp yarn sorting machine for sorting warp yarns according to their attributes.

[Prior Art] As is well known, when a warp beam attached to a loom runs out, the remaining bundle of yarns is transferred to the next warp to ensure continuity of the fabric being manufactured. It is necessary to tie it to the thread that will be used.

It is not possible with current technology to use partially shaped beams to knot this warp yarn in a proper manner. This is because if a partially shaped beam is used, the impact of the loom will cause the threads to become tangled or damaged.
This is because the room must be stopped frequently.

[Problem to be Solved by the Invention] In view of the above-mentioned actual situation, the first problem of the present invention is to use a partially shaped beam to completely separate the warp threads to be wound according to their attributes, and to separate the ends of the separated threads and It is an object of the present invention to provide a warp yarn sorting machine that can be used in a warp shaping machine such as a gluing machine or a beam rewinding machine, in which the trailing end is separated.

A second object of the invention is to completely automate a warp thread sorting machine of the above-mentioned type for gluing machines and the like.

A third object of the invention is to construct a device of the type mentioned in such a way that it is structurally simple and yet reliable in operation.

Further, in the first problem, it is also possible to make it possible to use the even numbered or odd numbered positions of a plurality of threads wound around a warp beam as an attribute.

[Means for Solving the Problems 1 To achieve the above-mentioned problems, a warp sorting machine according to the present invention includes a plurality of yarn feeding beams that supply yarn, a plurality of horizontal rods, and a plurality of toothed members. a separating comb, the number of horizontal ronds being equal to the number of yarn feeding beams;
This is configured to be able to be operated up and down according to a program, and is arranged so that the yarn sets released from each of the yarn feeding beams slide over the corresponding horizontal ronds, and are wound through the sorting combs on the lower side. The separating comber is configured to be capable of double movement in its layer plane, and further configured to selectively hold the yarn supported and raised by the horizontal rond by its relative position. It is assumed that the

[Function 1 With this structure, firstly, from the yarn feeding beam, the horizontal rond,
The yarn is placed through a sorting comb.

Here, the yarn set released from each yarn feeding beam is arranged to slide over the corresponding horizontal rond. Then, the plurality of horizontal rods are continuously operated to move upward in order from the upstream side to the downstream side. Accordingly, after each horizontal rod moves upward, the sorting comber makes a backward movement. Therefore, as the sorting comber reciprocates a plurality of times, the yarn sets of the respective yarn offering beams are alternately held in the sorting comber, and are subsequently released and slid upward.

After each of the above working cycles, sorting takes place through an opening formed between the two groups of threads. After completing the above steps, all horizontal rondes are lowered. Thereafter, the sorting comber performs the above-mentioned movement sequence in the reverse direction, and the yarn in the lowered position moves to the raised position, and conversely, the yarn in the raised position moves to the lowered position, and the yarn in the lowered position moves to the lowered position, and A work cycle begins. The yarn located in the lowered position is then sorted, after which the horizontal rond is lowered again.

According to the method described above, it is possible to accurately classify and separate yarns according to their attributes.

[Effects] With the above configuration, the partially shaped beam is used, the warp threads to be wound are completely separated according to their attributes, the leading end and the trailing end of the separated threads are separated, and gluing is done by machine or by machine. We were able to provide a warp sorting machine that can be used in a warp shaping machine such as a beam rewinding machine.

Furthermore, since the yarns supplied from each yarn feeding beam are generally even-numbered or odd-numbered yarns, it has become possible to reliably separate these yarns.

[Embodiment] The warp sorting machine according to the present invention has a sorting comb 1, that is, a sorting comb, and this sorting comb 1 includes a plurality of tooth-like members. The plurality of tooth-like members are configured to move smoothly parallel to each other to form a gap corresponding to the diameter of the yarn to be processed. Furthermore, and more particularly, these toothed members are composed of a plurality of corresponding lead members, each having an opposing threaded portion and a variable pitch, and a worm screw with a downwardly branching tab portion in the intermediate portion 2. connected in a spiral manner.

The sorting comber 1 configured as described above is attached to a sliding portion 3 that is capable of double movement and is driven by a pair of hydraulic or air cylinders 4. Furthermore, a support frame 5 is disposed upstream of the sorting comber 1, and this support frame 5 allows a plurality of corresponding horizontal rods 7 extending in the horizontal direction to move vertically in parallel. It supports the double acting cylinder 6. A support stand 8 is provided on the upstream side of the support frame 5, and this stand 8 includes:
It supports a plurality of yarn feeding beams 9, generally indicated by the reference numeral 10, which supply the yarn sets to be knotted. and,
The number of these yarn feeding beams 9 is equal to the number of horizontal rods 7. In this regard, a set of yarns released from each said yarn feeding beam 9 is arranged to pass over a corresponding respective horizontal rod 7, as shown in FIG. . This is important. On the other hand, on the downstream side of the sorting comber 1, a pantograph comber 11, a rotating cylinder 12, and a beam 13 for separating and winding the warp yarns 14 are arranged.

The separator further includes a central control unit consisting of a power supply circuit and a memory processing device for controlling the upward movement of the plurality of horizontal rods 7.

Further, this sorting machine is configured to accurately maintain constant tension on the yarn in both the warp forming process and the beam winding process.

Next, the operation of this separator will be explained.

First, the separation comber 1 and the pantograph comber 11
After threading the yarn, a work program is selected by operating an appropriate button on the operation panel 15 and specifying the number of yarn providing beams 9 for forming the warp yarns using the sorting system. Next, when the brisset push button on the panel 15 is operated, the thread sorting operation is started. That is, the plurality of horizontal rods 7 are continuously operated to move upward in order from the upstream side to the downstream side, and in conjunction with this, the sorting comber 1 performs a double movement after the upward movement of each horizontal rod 7. Therefore, the separation comb 1
By reciprocating a plurality of times, the sorting comber 1
By the lead or tab member formed in the middle part of
The yarn sets of each said yarn donor beam are alternately held and subsequently released and slid upwards.

After each of the above working cycles, an adhesive piece 16 or the like is introduced into the opening formed between the two groups of yarns, thereby fixing all the yarns located in the lowered position. After completion of the above steps, all horizontal rods 7 are lowered by actuation of another pushbutton. Thereafter, the sorting comber performs the above-mentioned movement sequence in the reverse direction, and the yarn in the lowered position moves to the raised position, and conversely, the yarn in the raised position moves to the lowered position, and the yarn in the lowered position moves to the lowered position, and A work cycle begins.

Next, an adhesive piece 16 is applied to the threads located in the lowered position to stick them together, after which the horizontal rod 7 is lowered again. According to the method described above, it is possible to accurately separate and separate the even-numbered yarns and the odd-numbered yarns forming the warp yarns, thereby separating the rear end of the used beam from the leading end of the next beam. It becomes possible to properly knot the

In particular, in the above method, each horizontal rod 7 rises within 6 to 8 seconds, which significantly shortens the operating time, so that when the method of the invention is used in a gluing machine for cotton yarn, The time required for setting the machine can be significantly reduced.

Moreover, the method is fully automated, so that the work can be carried out by one person.

As a characteristic feature of the present invention, the sorting comb is configured as a retractable type, thereby making it possible to accommodate yarns of various diameters. In this way, by sharing one type of sorting comb, the handling of the apparatus becomes easier for the user.

Although a preferred embodiment of the present invention has been described above, various modifications and improvements in addition to those described above are possible.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
