Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a comb clogging detection device in a warping process in which a large number of yarns are aligned and running, such as a warping device and a sizing machine.

(Prior Art) Conventionally, in order to align and run a large number of yarns in parallel, a comb in which a large number of needles are planted at a small interval is generally used in the traveling route of the yarn group. However, for example, when the yarn part to which the cotton wool adheres passes between the needles of the comb, abnormal friction or clogging causes yarn breakage, and if one yarn breaks, the yarn end stays If the running yarns in the vicinity are broken together, and the detection of abnormal friction and clogging is delayed, not only will it require a great deal of labor and time for repair, but also the quality will deteriorate in the next process. For the purpose of preventing the occurrence of such a situation, for example, JP-A-53-14850 or JP-A-
As described in Japanese Patent Laid-Open No. 58-207255, the above-described running yarn abnormality detecting device has been proposed.

(Problems to be solved by the invention) However, the detecting means in the above-mentioned conventional traveling yarn abnormality detecting device directs a thin light beam toward the light receiver in the width direction of the sheet surface of the aligned sheet-like yarns. Since it is projected and detects the attachment of thread waste or fly on the sheet surface to give an alarm or stop the machine base, the floating thread, slack thread or overlapping thread that can pass through the comb is actually detected as an abnormality. However, there is a problem that the frequency of alarm activation and machine standoff increases.

The present invention provides a comb clogging detection device capable of detecting an abnormality of a passing yarn at a portion of a comb through which the yarn passes and issuing an alarm, deceleration, or a machine stand stop.

(Means for Solving Problems) The present invention is directed to a warping process such as a warping machine or a gluing machine that uses a comb in which a large number of needles are implanted in order to run a large number of yarns in parallel. At the back of the yarn entry side of each needle of the comb, an elastic needle that elastically deforms toward the needle side due to abnormal friction with the running yarn is erected in an insulated state from the base of the comb, and the elastic needle bends. Then, when the needle comes into contact with the needle, it is energized to detect comb clogging.

The distance between the comb needle and the elastic needle is determined by the amount of bending elastic force of the elastic needle. During normal running of the yarn group, the comb needle is kept in non-contact with the sheet needle, When passing through the comb with dust and lint attached, when the friction above the normal running friction acts on the elastic needle due to these deposits, the elastic needle may bend greatly toward the needle side and contact the needle. Is set to.

(Operation) The comb has a function of running a large number of yarns in parallel and aligned in the same manner as before, and the elastic needles provided behind the yarn entry side of each needle of the comb move to the needle side due to abnormal friction of the traveling yarns. When the needle is elastically deformed and comes into contact with the needle, it is energized to detect it, and the control unit is activated to give an alarm, decelerate or stop the machine base to prevent the yarn breakage from spreading.

(Embodiment) Referring to the drawings showing an embodiment of the present invention, FIG. 1 is a side view of a needle portion of a comb, and FIG. 2 is a perspective view of a portion of a comb in a warp sizing machine. 1)
Is a sheet-like yarn group that is glued, dried and wound into a beam, and (2) is a comb in which a large number of needles (3) and (3) for making the yarn group (1) run in line are erected. Is.

In the comb (2) of the present invention, as shown in FIG. 1, the needles (3) and (3) of the comb (2) are attached to the needle (3) on the entry side of the yarn group (1). ) And an electrically conductive base (4) and a copper wire (5) supported by the base (4) at a distance from each other, and an elastic needle (6) is electrically insulated from the support frame (7) of the comb (2). Standing in an insulated state through the body (8), and joining the conductive wires (9) and (9) to the base portion (4) of the elastic needle (6) and the support frame (7) of the comb (2), respectively. Then, the conductive wires (9) (9) are connected to a gluing machine (not shown) and a beam driving unit (10), and for example, a part of the yarns of the yarn group (1) serves as a needle (3). When the friction of the needle causes the thread to break and the comb to be clogged, resulting in abnormal friction at a part of the needle (3), an abnormal external force is applied to the elastic needle (6), which is indicated by a broken line. As the deflection, the distal end sends a contact signal to the control unit in contact with the needle (3), in which none to reduce the running speed of the yarn group (1) with issuing a warning.

(Effect of the device) As described above, the comb clogging detection device of the present invention in the warping process such as the warping device and the gluing device has a large number of needles (3) (3) for causing the yarn group (1) to travel in line. Behind the yarn group (1) entry side of each needle (3) (3) of the comb (2) erected by the elastic needle (3) which is elastically deformable toward the needle (3) side due to abnormal friction with the yarn (3). 6) is erected in an electrically insulated state from the support frame (7) of the comb (2), and the elastic needle (6)
When the yarn bends and comes into contact with the needle (3), it energizes to detect comb clogging. Therefore, the yarn group (1)
When abnormal friction is added to the elastic needle (6), such as when cotton wool or thread waste is attached to a part of the needle, or when thread breakage occurs due to friction with the needle, the elastic needle bends. It is possible to accurately detect an abnormality that has occurred in a part of the traveling yarn, and prevent the occurrence of co-breakage and the spread of troubles by taking measures such as an alarm, deceleration, or stop of the machine base.
