[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal reel supporting device for rotatably supporting a terminal reel for sequentially supplying chain terminals to a terminal crimping mechanism for crimping a terminal to an end of an electric wire.

[0002]

2. Description of the Related Art Conventionally, as a terminal reel supporting device of this kind in a terminal crimping device, there is one having a structure shown in FIG. 8 as disclosed in Japanese Utility Model Laid-Open No. 7-27087.

That is, a terminal crimping device main body 2 is disposed on a machine base 1, and an anvil 3 is provided at a lower portion of the main body 2.
Immediately above the anvil 3, an elevating body 4 provided with a crimper is provided so as to be capable of ascending and descending operations.

A stand 5 is provided on the upper part of the main body 2 so as to protrude upward, and a support shaft 7 for detachably and rotatably supporting a terminal reel 6 loaded with a chain terminal is provided on the upper part of the stand 5. The structure is such that a chain terminal sequentially fed from a terminal reel 6 mounted on the support shaft 7 is divided by the cooperation of the anvil 3 and the crimper and crimped to the end of the electric wire.

When the terminal reel 6 is replaced due to the termination of the chain terminal or the change of the line type, the terminal reel 6 is turned around the axis of the stand 5 as shown by the phantom line in FIG. 5 is rotated around the horizontal axis at the lower end to make the terminal reel 6 in a horizontal posture, the replacement position in the replacement work is slightly lowered to eliminate the need for a step, etc. There was a structure with an improved structure.

However, when the terminal crimping apparatus is operated, the terminal reel 6 is held in an upright position above the main body 2, so that it is necessary to secure a large space above the main body 2, and the height of the ceiling is high. However, when a plurality of terminal crimping devices are provided side by side, the field of view deteriorates.

Therefore, as disclosed in Japanese Patent Application Laid-Open No. 10-12352, a structure has been proposed in which a terminal reel is housed and arranged in a gantry supporting a terminal crimping mechanism, and the terminal reel installation position is lowered. . In this case, when replacing the terminal reel, the terminal reel is pulled out from the gantry, and after the terminal reel is replaced, the terminal reel is housed in the gantry again.

[0008]

However, according to the structure disclosed in Japanese Patent Application Laid-Open No. 10-12352, a slide substrate on which a support for supporting a terminal reel is mounted is slid to move the terminal reel from within the gantry. This is a method of taking in and out, and a guide frame or the like for slidingly guiding the slide substrate is required, and there has been a problem that the structure is complicated.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a terminal reel supporting device having a simple structure in which terminal reels can be easily replaced.

[0010]

A technical means for achieving the above object is to sequentially supply a chain terminal to a terminal crimping mechanism provided on a gantry and having an applicator for crimping a terminal to an end of a wire. In a terminal reel supporting device that rotatably supports a terminal reel to be mounted, a base portion of a support bracket having a support shaft that detachably and rotatably supports the terminal reel is supported by the gantry in a swingable manner, Due to the swing operation of the support bracket, a chain terminal supply posture in which the terminal reel is disposed in a housed state in an internal space formed in the gantry, and a terminal reel protruding outside from the internal space and replaced. The point is that the attitude change operation can be freely performed between the possible reel replacement attitude.

The supply line of the chain terminal to the applicator and the supply line of the chain terminal fed from the terminal reel in the chain terminal supply posture may be arranged on substantially the same plane.

Further, a structure may be provided in which a stopper is provided for restricting the swing by allowing the support bracket to freely contact and separate at the swing position of the support bracket in the chain terminal supply posture.

Further, a structure may be provided which has a fixing mechanism for releasably fixing and holding the support bracket at both ends of the swing operation range and at an intermediate position therebetween.
