Description

An Apparatus for Making a Multi-Channeled Pipe for Cables}

The present invention relates to a porous line manufacturing apparatus for a communication line for manufacturing a porous line for a communication line used to receive and protect a communication line requiring an independent occupied space, such as a telephone line or an optical cable.

Communication lines such as telephone lines and optical cables are usually buried underground. In this case, hollow tubes for communication lines have been mainly used to protect communication lines from earth pressure and groundwater.

In performing the communication line laying construction using the hollow tube for the communication line, the guide tubes are used together to wire a plurality of communication lines in a separate space inside the hollow tube for one communication line.

These guide tubes have been introduced to have a variety of forms, but in recent years a band-shaped guide tube is produced and distributed so that a plurality of small tubes are integrally connected to each other as a connecting strip.

This strip-shaped guide tube is inserted inside the hollow pipe for communication line with the small pipes curled to maintain a constant interval, so that the small pipes do not twist inside the hollow pipe for communication line and maintain a constant distance therebetween. In addition, there was an advantage that the internal area of the hollow tube for the communication line can be utilized to the maximum.

However, when performing the construction of the communication line using the hollow pipe for the communication line together with the excellent strip-shaped guide tube, the work of laying the hollow tube for the communication line and inserting the guide tube must be carried out separately. There was a problem that can not significantly reduce the construction cost.

On the other hand, the present applicant has been making efforts to develop the piping material for the communication line, and as a result of the patent application No. 26147 (1999.6.30) in 1999, the applicant for the communication line perforated tube and its manufacturing method and manufacturing apparatus.

The apparatus for manufacturing a porous pipe for a communication line according to the present invention has a plurality of small pipes which are bundled into a predetermined bundle and inserted into the inside of the small-sized pipe, which is inserted into the inside of the plurality of small pipes. Outer tube for supplying molten resin to the outer peripheral surface of the bundle pipe, and an outer tube for forming a molten resin next to the molten resin supply means and covered with the outer peripheral surface of the bundle pipe in the form of an outer tube Forming means, cooling means for cooling the outer tube disposed next to the forming means of the outer tube and shaped into a predetermined shape, and a plurality of compacts disposed after the cooling means and integrally bound inside the outer tube. The pipes consisted of the withdrawal means of the perforated tube, which draws out the finished one.

The apparatus for manufacturing a porous pipe for a communication line according to the present invention is provided with a plurality of small pipes which are bundled into bundles, and the preformed bundle pipes are passed through the bundle pipe inlet means, and are supplied from the molten resin supply means to the outside of the bundle pipes. After covering the molten resin and passing the forming means of the outer tube, by forming the outer tube integrally on the outer circumferential surface of the small-sized pipes, not only can maximize the effective effective area than the general hollow tube, but also guide tubes separately It is possible to obtain a multi-core tube for communication line, which has the advantage of greatly reducing the overall construction cost since there is no need to insert work.

However, the apparatus for manufacturing a porous pipe for a communication line according to the present invention provides a bundle-shaped tube made of a ready-made product, while covering the outer surface of the bundle-shaped tube with a molten resin to form an outer tube. Since the small-sized pipes passing through the small pipe inlet means are not deformed or deformed or partially melted, they are severely deformed, and as a result, the perforated pipe for the communication line manufactured as a finished product when performing the construction of the communication line There was a serious problem of not being able to insert a communication line into the bundle compact tube of the.

In addition, since the small-sized tubes made of ready-made products and the newly formed outer tubes could not be reliably bonded to each other, the outer tubes and the small-sized tubes were easily buried in the ground or embedded in the ground. Not only do they lose the function as a piping material by separating the material, there are problems such as the small pipes are randomly twisted in the outer tube can not efficiently perform the operation of inserting the communication line.

The present invention is a communication line that is made so that the small-sized pipes made of ready-made products to be firmly bonded to the outer pipe newly formed in the original form, so as to obtain a porous pipe for a communication line excellent in quality and workability required as a piping material. The purpose is to provide a porous pipe manufacturing apparatus for the purpose.
