Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a cable vertical attachment device for vertically attaching an aluminum laminate tape to a cable, and in particular, the diameter of the cable can be changed after the start of production without preparing a forming die for each type of different diameter of the cable. Even if it becomes necessary to cut the cable and aluminum laminating tape each time and change the forming die continuously, change the hole diameter to match the diameter of the cable and vertically attach the aluminum laminating tape to the cable. The present invention relates to a tape vertical attachment device for a cable.

[Prior art]

In general, when the signal to be transmitted among the control cables is weak, there is a great risk that the controlled object will malfunction due to inductive interference from other electric wire cables or electric railways of electric railways. For this reason, it is necessary to shield the control cable so as not to be subject to inductive interference from such other electric wire cables or electric railway lines. This shield includes electrostatic shield and electromagnetic shield. The electrostatic shield is a shield required when there is a high-voltage electric wire near the control cable, and is shielded by winding an aluminum laminated plastic tape on the cable core. The electromagnetic shield is a shield required when a large current flows near the control cable, and is shielded by wrapping an iron tape on the cable core having an aluminum laminate sheath. The aluminum laminate sheath used for this electrostatic shielding is A
A composite sheath made of l (aluminum) tape and PE (polyethylene), both of which are physically integrated to form a sheath, which is mainly used as a sheath for communication cables. This aluminum laminated sheath has a thin film layer of plastic which is easy to adhere to PE (polyethylene) for sheath, formed on both sides or one side of a soft aluminum tape having a thickness of around 0.2 mm in advance. Tape) is formed vertically on the cable core, and PE is placed on top of it.
Is extruded and coated to be integrally formed. For this reason, a sheath having a low moisture permeability is obtained, line interference due to moisture infiltration is reduced, and an advantage is obtained that the shielding effect is obtained by the Al tape. Further, there is an advantage that the sheath (PE) is less likely to shrink over time. The vertical attachment of this aluminum laminate tape is conventionally
As shown in the figure, this is carried out by a cable vertical attachment device 100. That is, the tape vertical attachment device 100 for this cable preforms a tape stand 120 that continuously supplies the vertical tape 110 and the vertical tape 110 that is continuously supplied from the tape stand 120 into a predetermined cylinder diameter. Taper tube 130 and a taper tube 130 provided behind the taper tube 130.
And a forming die 150 that is formed on the cable 140 that continuously travels and is vertically aligned closely. The vertical attachment of the vertical attachment tape (aluminum laminate tape) 110 by the tape vertical attachment device 100 of this cable is first performed by continuously attaching the vertical attachment tape 110 to the taper tube 130 from the tape stand 120 on which the vertical attachment tape 110 is wound. At the same time as the supply, the cable 140 is supplied, and the vertical tape 110 is preformed into a predetermined tube diameter so as to wrap the cable 140 in the tapered tube 130. Next, the vertical tape 110 preformed so as to wrap the cable 140 in the taper tube 130 is attached to the cable 1 by the forming die 150.
It is formed on 40 so as to be dense and vertically arranged.

[Problems to be solved by the device]

In this way, the vertical tape (aluminum laminate tape) is vertically attached on the cable. The forming die used for this vertical attachment is conventionally used to wind the vertical tape on the outside of the cable. It is formed in a cylindrical shape or a ring shape having an inner diameter of a sufficient diameter. For this reason, when the outer diameter of the cable vertically attached in this forming die changes in size, the forming die must be replaced each time according to the diameter of the cable, which requires a lot of trouble. There is. Also, when manufacturing several types of cables with different outer diameters of vertically attached tape (aluminum laminate tape), it is necessary to prepare in advance a number of forming dies corresponding to the type of outer diameter. However, there is a problem in that a storage place for the forming die must be secured. Furthermore, when it is necessary to change the diameter of the forming die due to the fact that the originally designed and manufactured cable diameter cannot obtain the originally designed characteristics, the conventional forming die has a cylindrical or ring shape. Since it is formed in a shape, in order to replace the forming die, it is necessary to stop the line once and cut the continuously supplied cable and vertical tape (aluminum laminated tape),
It has a problem of poor productivity. The present invention has been made in view of the above problems of the conventional technology, and an object of the present invention is to prepare a forming die for each type of cable having different diameters, and Even if it is necessary to change after the start of manufacturing, the cable and aluminum laminate tape are cut each time, and without changing the forming die, the hole diameter is continuously changed to match the diameter of the cable and the aluminum laminate tape is attached to the cable. An object of the present invention is to provide a tape vertical attachment device for a cable that can be attached vertically.

In order to achieve the above-mentioned object, the device for vertically adhering a tape of a cable according to the present invention is a device for vertically adhering an aluminum laminate tape on a cable that continuously runs, and a device for vertically adhering a tape is provided on the outer peripheral side surface of a roll. A tape bent at a predetermined curvature so as to wrap the cable inside a taper tube by installing a pair of rolls formed around a groove whose curvature changes steplessly so as to be adjacent to each other on the outer peripheral side surface. The forming die is provided to vertically attach the cable to the cable. In addition, in order to achieve the above object, the cable tape vertically adhering device according to the present invention is a cable tape longitudinally adhering device in which an aluminum laminate tape is vertically laid on a continuously traveling cable. By installing a pair of rolls, each having grooves with different curvatures in the tangential direction on the outer peripheral side surface of the roll, adjacent to each other on the outer peripheral side surface, the taper tube is bent to have a predetermined curvature so as to wrap the cable inside. The forming die is provided to vertically attach the tape to the cable.

[Action]

When using the forming die configured as described above and vertically attaching the aluminum laminate tape on the cable that runs continuously, even if the outer diameter of the cable changes, adjust it according to the diameter of the cable. Even if the forming die is not changed each time, it is possible to set the forming die having a required inner diameter by simply rotating the forming die by a predetermined angle so as to have a diameter that matches the diameter of the cable. Therefore, it is not necessary to prepare a forming die for each type of cable having different diameters. Further, when using the forming die configured as described above and vertically arranging the aluminum laminate tape on the cable that continuously runs, even if it is necessary to change the diameter of the cable after the production of the cable is started.
