この発明は、自己支持型ケーブルの製造装置、特に支持
線と外被との間に滑りが生じない自己支持型ケーブルの
製造装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for manufacturing a self-supporting cable, and more particularly to an apparatus for manufacturing a self-supporting cable in which no slippage occurs between the support wire and the jacket.
自己支持型ケーブル（以下ＳＳケーブルという）を製造

れる。Conventional equipment for manufacturing self-supporting cables (hereinafter referred to as SS cables) generally involves unwinding each wire from a drum around which the cable core and support wire are wound, and introducing the wires into an extrusion molding machine to separate the cable core and support wire. The jacket is integrally extruded through the neck part in between, and then this extruded S
The S cable is cooled by passing it through a cooling water tank, is taken up by a take-up machine, and is wound up on a drum attached to the take-up machine.

れと並行して上記コアーを支持する支持ｍ（亜鉛メツキ
鋼撚線）を押出成形機に導入してコアーと支持線との間
に首部を介してコアーと支持線上に外被を一体的に押出
成形したものから成る。SS cables manufactured by such manufacturing equipment are made by assembling twin-twisted or star-twisted insulated core wires and wrapping them with identification tape or outer paper to form a cable core (hereinafter referred to as core). On top of that, an aluminum polyethylene laminate tape is formed into a cylindrical shape and then introduced into an extrusion molding machine.In parallel with this, a support m (galvanized steel stranded wire) that supports the core is introduced into the extrusion molding machine to form a core. It consists of a core and an outer sheath integrally extruded onto the support wire with the neck interposed between the core and the support wire.
とご−ろで、支持線はコアーを支持するものであリ、支
持線とその上に形成される外被との間で滑りが生ずると
支持線としての役目を果さなくなる。The supporting wire supports the core, and if slippage occurs between the supporting wire and the jacket formed thereon, it will no longer function as a supporting wire.
具体的には、ＳＳケーブルの架渉に際して支持線上の外
被の上から層線器により支持線を掴持してＳＳケーブル

りが生ずると、架渉張力により外被だけが伸びてケーブ
ルが抜は落ちるといった事故が発生する恐れがある。従
って、支持線と外被との間に滑りがあってはならず密着
している必要がある。Specifically, when the SS cable is strung, the support wire is grasped from above the outer sheath on the support wire by a layered cable, and the SS cable is pulled and strung. At this time, if slippage occurs between the outer sheath and the support wire, there is a risk that only the outer sheath will stretch due to the striding tension, causing an accident in which the cable will be pulled out and fall. Therefore, there must be no slippage between the support wire and the outer sheath, and they must be in close contact.
一方、支持線は前述の如く亜鉛メツキ鋼撚線から成り、
亜鉛メツキ線は表面が粗く、支持線が押出成形機を通過
する間にメツキが剥れてニップルランドに堆積しそれが
詰まって品質を低下させる。On the other hand, the support wire is made of galvanized steel stranded wire as mentioned above.
Galvanized wire has a rough surface, and while the support wire passes through an extruder, the plating peels off and accumulates on the nipple land, clogging it and reducing quality.
そこで、上記ニップルランドにメツキの剥れ層が詰まら
ないようにするために、支持線を構成する亜鉛メツキ鋼
線を撚線とする前に潤滑油を塗布して伸線ダイスを通過
させ、表面を滑らかにして前述の問題を解決しようとす
る方法が提案された。Therefore, in order to prevent the peeled layer of plating from clogging the nipple land, lubricating oil is applied to the galvanized steel wire constituting the support wire before it is stranded, and the wire is passed through a wire drawing die. A method has been proposed that attempts to solve the aforementioned problem by smoothing the
上記提案によってメツキが剥れてニップルランドに詰ま
るという問題は解決されたが、その反面伸線ダイスを通
す前に塗布した潤滑油が亜鉛メツキ鋼線の表面に残り、
支持線と外被との間で滑りが生ずる。The above proposal solved the problem of the plating peeling off and clogging the nipple land, but on the other hand, the lubricating oil applied before passing through the wire drawing die remained on the surface of the galvanized steel wire.
Slippage occurs between the support line and the jacket.
この問題の対策として、支持線をトリクロルエタン等の
有機溶削等で洗浄することも行なわれるが、この方法で
は支持線の撚りの内部まで除去することはできず、父上
記溶剤はバーチエツト病等の原因となるなど有害物であ
るため、好ましい対策であるとは云い難い。As a countermeasure to this problem, cleaning the support wire with an organic abrasion such as trichloroethane is also carried out, but this method cannot remove the inside of the strands of the support wire, and the above solvent may cause problems such as Birchiet's disease. It is difficult to say that this is a desirable countermeasure because it is a harmful substance that can cause

己支持型ケーブルの製造装置を提供するにある。This invention was made in view of the above-mentioned problems with the conventional self-supporting cable manufacturing equipment, and its purpose is to eliminate the peeling layer of plating in the nipple land by using a support wire with a smooth surface. An object of the present invention is to provide a self-supporting cable manufacturing device that prevents clogging and eliminates slippage between a support wire and a sheath that occurs when a peeling layer occurs.

のである。Therefore, in this invention, as a means to solve the above problem, the cable core and the support wire are introduced into an extrusion molding machine in parallel, and the outer sheath is integrally extruded through the neck between the cable core and the support wire. In a manufacturing device for self-supporting cables, a group of burners is arranged to move up and down along a support line introduced upstream of an extrusion molding machine, and the burners are selected in conjunction with the extrusion speed of the support line. The construction of a self-supporting cable manufacturing apparatus was adopted in which the lubricating oil applied to the support wire was burnt or volatilized by the flame.
上記のように構成したこの発明による自己支持型ケーブ

押出機のクロスヘツドに送られて首部を介してその外周
に外被が一体的に押出成形され、その後冷却水槽で冷却
“された後引取機で引取られ、巻取機のドラムに巻き取
られる。In the self-supporting cable manufacturing apparatus according to the present invention configured as described above, the cable core and support wire are sent to the crosshead of an extruder in the same way as in the past, and the jacket is integrally extruded around the outer periphery of the cable through the neck. After being molded and then cooled in a cooling water tank, it is taken up by a take-up machine and wound onto a drum of a take-up machine.
そして、上述した押出機のクロスヘツドにケーブル芯と
支持線が送られる前に、その上流に設けたバーナ群によ

持線の送り速度に連動して選択的に、即ち支持線の送り
速度が大になるとバーナ群の数を多く支持線に対して上
昇させ、速度が小さくなるとバーナ群の数を減少せしめ
てそれぞれ作動状態にする。Before the cable core and support wire are sent to the crosshead of the extruder described above, the support wire is preheated by a group of burners provided upstream thereof. In this case, the number of burner groups is selected selectively in conjunction with the feed speed of the support line, that is, when the feed speed of the support line increases, the number of burner groups increases relative to the support line, and when the speed decreases, the number of burner groups increases relative to the support line. The number of groups is reduced and each is brought into operation.
このため、支持線の送り速度に比例して最適のバーナ群
の火炎により支持線内及び表面に付着した潤滑剤が燃焼
又は揮散されて除去される。従って、支持線と外被との
間の滑りのない自己支持型ケーブルが製造できる。Therefore, the lubricant adhering to the inside and surface of the support wire is burned or volatilized and removed by the flame of the optimal burner group in proportion to the feed speed of the support wire. Therefore, a self-supporting cable without slippage between the support wire and the jacket can be produced.

It will be done. This is because the gas burners 52, 52a are of different sizes, and the three gas burner devices may all be of the same size so that the gas injection amount can be adjusted. The flame of the gas burner 52, 52a is injected from the downstream position of each tube toward the upstream side of the tube.

滑りが防止される。When the speed at which the support wire 4 is extruded by the crosshead 8 becomes low, the amount of flame injected to the support wire 4 becomes excessive, so the gas burner devices 5(1) to 5(3) are It can be raised and lowered by an air cylinder 53. When the extrusion speed is low, a solenoid valve (
(not shown), the air cylinder 53 is lowered to reduce the burner power as shown by the dashed line in FIG. 2, and when the linear velocity increases, the air cylinder 53 is raised to increase the burner loss. In this way, the optimal number of gas burner devices is selectively operated according to the increase or decrease in the linear speed of the support wire 4, and the lubricant adhering to the surface of the support wire 4 and its strands is burned or volatilized by the flame of the gas burner. Slippage between the support wire and the jacket is prevented.
