Description

Method for continuous manufacturing combined cables}

The present invention relates to a method for continuously manufacturing a combinatorial cable, such as a union (for power), aggregation (for instrumentation), and sheathing (neutral wire (high-voltage cable), steel wire sheathing) for electric power and instrumentation by combining a plurality of twisted-pair cables. will be.

In general, cables have a structure in which one or multiple core wires are placed in the center and the outer layer is coated with an insulating material. In particular, a form in which multiple single wires are twisted and combined is called a twisted pair cable, and cables of various specifications are available depending on the purpose of the cable. This is produced.

As shown in FIG. 1, a plurality of twisted pair cables 11 are combined according to the purpose to provide a combined cable 10 consisting of a covering layer 12, and when an exterior is required depending on the usage conditions, a copper wire (high-voltage cable neutral wire) is provided. ), or an exterior may be added such as a steel wire exterior.

Referring to FIG. 2, the manufacturing process of a general stranded cable largely consists of two dual processes (L1) and (L2) consisting of a manufacturing process for a twisted pair cable and a process for manufacturing a final stranded cable by combining the twisted pair cables.

The manufacturing process (L1) of a stranded cable includes a drawing process (S10) in which a wire of a certain thickness is processed into a thin wire of a desired thickness, a stranding process (S20) in which the processed fine wire is twisted to manufacture a single strand, and the combined strand is It is manufactured through an insulation process (S30) in which a twisted pair cable is manufactured by forming an insulating sheath.

Next, in the stranded cable manufacturing process (L2), the worker transports the stranded cable produced in the stranded cable process line to the stranded cable process (or assembly process) line to knit the stranded cable (S40), and forms an exterior coating layer. It consists of a process (S50) and is divided into two processes.

In particular, in the cable manufacturing process (L2), various facilities (combination machine/aggregator/exterior machine, etc.) must be appropriately configured and placed at the production site depending on the type of cable. However, since there are many different types of cables, it is realistically difficult to automate it by rearranging unit equipment (combiner/aggregator/outer unit, etc.) suitable for the type of cable at the production site. In general, at the production site, workers are assigned to each unit facility. There is a problem in that productivity is very low because workers directly transport semi-finished products for which unit processes have been completed to subsequent processes.

Referring to FIG. 3, the continuous manufacturing system of a combined cable according to an embodiment of the present invention includes a unit facility unit 110 in which two or more types of plural unit facilities are arranged adjacent to each other and a unit facility unit 110. It includes a common accumulator 120 for accumulating semi-finished cables delivered from one unit and performing continuous work, and an extruder 130 for extruding the semi-finished cables supplied from the common accumulator 120.

Each unit facility (111) (112) (113) can be supplied with a bobbin wound with a twisted pair cable (20) produced through a wire drawing process, a stranding process, and an insulation process, and the cable manufactured among the unit facility units 110 Depending on the type, one of the combined unit 111, the collection unit 112, the external unit 113, or the neutral wire external unit is used as an alternative.

Specifically, the combiner 111 may be a combiner for manufacturing commonly used general products (TFR-CV, CV), It can be used in the production of joint cables ranging in size from 35 sq to 300 sq. The aggregator 112 may be an aggregator for manufacturing various instrumentation products (CVV, CVVS, CVV-SB), etc., and can be used to manufacture aggregation cables of sizes such as 1.0 sq ~ 4 sq. The sheath 113 is made of copper wire (high-voltage cable neutral wire) or iron wire sheath, depending on the cable usage conditions.

The common accumulator 120 serves to accumulate semi-finished joint cables so that the manufacturing process of the joint cable can be continuously automated and is composed of a fixed driving wheel 121 and a movable idle wheel 122. The semi-finished cable is maintained at a certain tension and accumulated, and the semi-finished cable is supplied to the extruder 130 as the process continues.

Preferably, the common accumulator 120 appropriately selects the size (diameter) of the wheel in consideration of the outer diameter of the semi-finished product, and allows the semi-finished product to be sufficiently accumulated by maximizing the available space at the facility site.

This common accumulator is provided by a horizontal accumulator installed horizontally at the production site, and in another embodiment, it is provided by a vertical accumulator installed vertically, thereby solving the lack of installation space at the production site.

Preferably, it further includes a guide roller unit 121 provided between the common accumulator 120 and the extruder 130 to maintain the semi-finished cable at a constant tension.

In the continuous manufacturing system of the combined cable of the present invention configured as described above, one unit facility (combined device/aggregator/exterior device, etc.) is selected among the unit facility units 110 according to the cable standard (type) to be manufactured. A bobbin on which the stranded cable 20 is wound is installed in the corresponding unit facility, and then accumulated in the common accumulator 120 and continuously supplied to the extruder 130, where extrusion molding is performed, and then produced as a final stranded cable.

This invention allows semi-finished cables to be worked continuously by appropriately electrically synchronizing the operation speeds of the unit equipment unit and the extruder, thereby accumulating the semi-finished cables manufactured in the unit equipment unit in a common accumulator and continuously supplying them to the extruder. Because this is possible, field inefficiencies caused by idle facilities at the production site can be improved. Additionally, through automation of the process, the number of workers can be significantly reduced compared to the past and productivity can be increased.

In particular, the present invention, which has the layout described above, can be very effective in manufacturing long-length cape products that require continuous processes, and can reduce the number of workers compared to the prior art. and can increase productivity.
