Abstract

(57) [Abstract] [Purpose] The present invention has a wide variety of electric wire markers.
The purpose is to automate the work of attaching the cable to the electric wire. [Structure] A plurality of suction nozzles 1 spread an electric wire mark 2 from the outer peripheral portion in a diameter direction in a state of being sucked by a vacuum pump 6, and after inserting an electric wire 3 therein, the suction is released.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mounting an electric wire mark tube on an electric wire, and more particularly to an electric wire mark tube mounting method applicable to a wide variety of electric wire mark tubes.

[0002]

2. Description of the Related Art Conventionally, a general electric wire mark tube to be attached to an electric wire has a small diameter difference between an inner diameter of the electric wire mark tube and an outer diameter of the electric wire and is not suitable for automatic mounting. In addition, conventional automatic wire mark tube mounting machines use a dedicated wire mark tube, and there are restrictions on the wire diameter and wire mark tube that can be used, and it often does not match the user's specifications at the product delivery destination. It was

Further, Japanese Patent Application Laid-Open No. 63-105410 is to attach a tape.

[0004]

The former of the above-mentioned prior art requires a dedicated electric wire mark tube for automation, and it is impossible to cope with a wide variety of existing electric wire diameters and specifications of users at product delivery destinations. It was Therefore, most of the work of attaching the electric wire mark tube is performed manually. In addition, even when it is manually mounted, it takes a lot of time because the diameter difference between the inner diameter of the electric wire mark tube and the outer diameter of the electric wire is small.

In the latter, the tape is easily peeled off.

An object of the present invention is to automate the mounting work of the electric wire mark tube by developing a mechanized mounting method corresponding to various existing electric wire mark tubes.

[0007]

In order to achieve the above object, the outer peripheral portion of an electric wire mark tube, which is marked with an identification mark and cut into a certain length, has a low pressure side as the outer peripheral portion and a pressure difference is provided between the inner peripheral portion and the outer peripheral portion. The electric wire mark tube is attracted to a jig, and the electric wire mark tube is expanded in the diameter direction by this jig to facilitate the insertion of the electric wire.

[0008]

Function: The electric wire mark tube is sandwiched by a jig having a suction function, and the outer peripheral portion of the electric wire mark is adsorbed to the jig. Further, by expanding the jig, the wire mark tube is expanded in the diameter direction within the elastic range, and the wire is inserted. After insertion, by opening the suction function of the jig,
The electric wire mark tube is elastically disengaged from the jig and attached and fixed to the electric wire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

An electric wire mark tube 2 which is engraved with an identification mark and cut into a certain length is placed on a jig, for example, in the center of six suction nozzles 1 which are radially provided. The six suction nozzles 1 linearly move in conjunction with each other on the radiation by the interlocking mechanism with the cylinder 4 provided in each suction nozzle 1.

When the suction nozzle 1 is moved by the cylinder 4 and brought into contact with the outer peripheral portion of the electric wire mark tube 2, the suction valve 5
Open, the air inside the six suction nozzles 1 is evacuated by the vacuum pump 6, and the inside of the suction nozzle 1 becomes a negative pressure with respect to the atmosphere, and the wire mark tube 2 is adsorbed by the suction nozzle 1.
When this suction is completed, the suction nozzle 1 is moved outward by the cylinder 4 to spread the electric wire mark 2 in the diametrical direction within its elastic range, and the electric wire 3 is inserted into the electric wire mark 2 in this state. To do. Next, when the suction valve 5 is opened to the atmosphere side, the electric wire mark tube 2 is opened from the suction nozzle 1,
As a result, the electric wire mark 2 is detached from the suction nozzle 1 by the elasticity thereof and is fixedly attached to the electric wire 3.

[0012]

According to the present invention, the effect of automating the work of mounting an electric wire mark tube that is compatible with a wide variety of existing electric wire mark members can be obtained.
