Problems solved by technology

[0008] However, if image 3 The nozzle device 115 shown has the problem that the toner is difficult to mist at the start of spraying, and it is difficult to spray a small amount of toner
like Figure 4 The nozzle assembly 215 shown also suffers from the same problem of being difficult to spray a small amount of toner
That is, the nozzle assembly 115, 215 is not suitable for intermittent spraying in which a predetermined amount of toner is sprayed per spray.

Embodiment Construction

[0044] The following will combine figure 1 and 2 A wire coloring device (hereinafter referred to as "coloring device") including a coloring unit having a coloring nozzle according to a preferred embodiment of the present invention will be described. This coloring apparatus 1 cuts an electric wire 3 as an article into a predetermined length, and paints the outer surface 3a of the wire 3 over the entire periphery. That is, the coloring device 1 colors or marks the outer surface 3 a of the wire 3 .

[0045] The wire 3 constitutes a wire harness to be mounted on an automobile as a mobile device. like figure 2 As shown, each wire 3 includes a conductive core wire 4 and an insulating coating 5 . A plurality of elementary wires are wound together to form the core wire 4 . Each base wire is made of conductive metal. Alternatively, the core wire can also be formed from only one basic wire. The coating 5 is made of synthetic resin such as polyolefin. Polyolefins are not easy t...

Abstract

The present invention discloses a coloring nozzle, by which a predetermined amount of the coloring agent per ejection can be securely ejected toward an electric wire, the ejected coloring agent can be quickly dried, and the nozzle is prevented from being blocked. The coloring nozzle (15) includes: a nozzle part (20) inside of which a coloring agent flows, a nozzle cover (21) which covers an end part (20b) of the nozzle part (20), a first pipe (7) which connects a pressurized gas supplying source (16) with a space S within the nozzle cover (21), and a second pipe (8), an end of which is connected to the center of the first pipe (7) through a selector valve (6) and, an opposite end of which is connected to a cleaning liquid-receiving part (18). The selector valve (6) is controlled in such a way that only the pressurized gas from the pressurized gas supplying source (16) is allowed to pass to the nozzle part (20) when the coloring agent is ejected from the nozzle part (20), while only the nozzle-cleaning liquid from the cleaning liquid-receiving part 18 is allowed to pass to the nozzle part (20) when the coloring agent is not ejected from the nozzle part (20).

Description

technical field [0001] The present invention relates to a coloring nozzle for coloring an item such as an electric wire comprising a conductive core wire and an insulating coating covering the conductive core wire. Background technique [0002] Various electronic instruments are installed in a car as a mobile device. Therefore, cars are equipped with wiring harnesses that carry power from the power source to the electronics and control signals from the computer to the electronics. The wire harness includes a plurality of wires and connectors attached to the ends of the wires. [0003] An electric wire (that is, a wire) includes a conductive core wire and a coating made of insulating synthetic resin that covers the core wire. This wire is called a covered wire. The connector includes a terminal fitting and a connector that receives the terminal fitting. When the connector housing is connected to the electronic instrument, the wire is electrically connected to the electron...
