Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal reel holding device and, more particularly, to a method for efficiently attaching and detaching a terminal reel to and from a support shaft which rotatably holds the terminal reel. .

[0002]

2. Description of the Related Art In general, in a terminal crimping apparatus, a terminal is crimped to an end of an electric wire while separating chain terminals one by one. Usually, the chain terminal is wound around a drum-shaped terminal reel, and a holding device for the terminal reel is disclosed in JP-A-9-23263.

In the terminal reel holding device, as shown in FIG. 6, a terminal reel 1 is rotatably held on a support shaft 4 which is horizontally protruded from a machine frame 3 of a terminal crimping machine 2, and has a chain terminal T. The terminal reel 1 rotates with the extension. In order to prevent the terminal reel 1 from falling off from the support shaft 4, a stopper 5 for preventing the terminal reel 1 from being detached is detachably fitted to the tip of the support shaft 4. The stopper 5 is movable to apply a predetermined rotational resistance to the terminal reel 1 by pressing the terminal reel 1 with a fixed side cylinder 5a fixed to the support shaft 4 via a fixing screw 6 and a compression coil spring 5b. It consists of a cylinder 5c. The reason why the predetermined rotation resistance is given to the terminal reel 1 is that when the chain terminal T is pulled along with the consumption of the chain terminal T in the terminal crimping machine 2, the terminal reel 1 continues to rotate excessively. This is to prevent the extra chain terminal T from being fed out. If the chain terminal T is extended excessively, there is a possibility that the chain terminal T will interfere with other members and be deformed.

[0004]

In the terminal reel holding device as described above, each time the terminal reel 1 is replaced, the stopper 5 for preventing falling off must be detached and attached. In addition to the need for trouble, there is also a risk that the removed stopper 5 may be lost. In addition, when the stopper 5 is mounted, the stopper 5 must be pushed in against the compression pressure of the compression coil spring 5b in order to impart rotational resistance to the terminal reel 1, so that the workability of the mounting operation is more difficult. I was supposed to.

The present invention has been made in view of the above-mentioned problem, and in order to prevent the terminal reel from falling off from the support shaft, the terminal reel can be detached from the support shaft without attaching another member such as a stopper. It is an object of the present invention to improve the workability so that the work can be performed with one touch.

[0006]

In order to achieve the above-mentioned object, the present invention relates to a terminal reel having a terminal reel wound with a chain terminal inserted through a support shaft horizontally projected from a machine frame. In a terminal reel holding device configured to rotatably hold a reel, a receiving area of a support shaft for holding the terminal reel is recessed in a radially smaller direction than a tip end of the support shaft, and the receiving area and the tip end are recessed. A locking step is formed at the boundary with the outer periphery of the center hole of the terminal reel to prevent the terminal reel from falling off, and the base is externally fitted to the base of the support shaft. A rotating plate is rotatably fitted between the substrate and the machine frame while being fixed, and a compression coil spring mounted on a support shaft is interposed between the rotating plate and the machine frame to rotate the rotating plate. A brake mechanism that presses the rotating plate toward the substrate to apply rotational resistance to the rotating plate. And projecting the member provides a holding device terminals reel so that rotation interlocking the rotating plate and the terminal reel by connecting to the terminal reel via the brake mechanism.

More specifically, the locking step is formed by cutting so that the outer diameter of the receiving area of the support shaft is smaller than the outer diameter of the distal end, or another member is integrally formed as the distal end. It is formed by attaching it in a way. Further, the locking step does not necessarily need to be provided on the entire circumference of the support shaft, and may be formed at least on the upper surface of the support shaft. Further, a shaft member is horizontally protruded from a rotary plate as the connection member at a position corresponding to a hole formed in advance at an eccentric position of the end surface of the terminal reel, and the shaft member is inserted into the hole. The terminal reel and the rotating plate are linked to rotate.

With the above construction, when the terminal reel is replaced, when the center hole of the terminal reel is inserted into the support shaft so that the edge of the center hole passes through the locking step, the terminal reel is replaced. The reel is rotatably held in contact with the upper surface of the spindle in the receiving area by its own weight. In this state, when the terminal reel attempts to move along the upper surface of the support shaft in the detaching direction, the edge of the center hole comes into contact with the locking step, so that the terminal reel is prevented from falling off from the support shaft. You. On the other hand, when removing the terminal reel, the terminal reel can be easily pulled in the pull-out direction by slightly lifting the terminal reel to release the locked state with the locking step.

Furthermore, when the terminal reel is mounted on the support shaft,
By simply connecting the rotary plate via the connecting member, the rotation resistance of the rotary plate given by the action of the compression coil spring can also act on the terminal reel. Therefore, it is possible to prevent the terminal reel from rotating excessively and the extra chain terminal being fed out due to the intermittent pulling operation accompanying the consumption of the chain terminal from the crimping machine side. Further, since the above-mentioned brake mechanism is provided in advance on the support shaft side and the pressing force of the compression coil spring does not directly act on the terminal reel, the pressing force is adjusted each time the terminal reel is mounted, or the pressing force is adjusted. There is no need for time-consuming mounting.

It is preferable that the fixed position of the substrate can be adjusted in the axial direction of the support shaft so that the rotational resistance of the brake mechanism can be adjusted. With this configuration, it is possible to easily adjust the rotation resistance optimal for the extension of the chain terminal according to the type of the terminal reel only by adjusting the mounting position of the substrate with respect to the support shaft.

In this state, the outer peripheral edge of the central hole 11b of the terminal reel 11 is locked to the locking step 14d of the support shaft 14, and the movement of the terminal reel 11 in the pull-out direction is restricted.
Therefore, the terminal reel 11 can be held without requiring a separate member such as a stopper. At the same time, the connecting member 16e
Is inserted into the hole 11c, the terminal reel 11 and the rotating plate a are brought into an interlocking state, and the terminal reel 11 is indirectly provided with rotation resistance by the brake mechanism 16.

In the holding state of the terminal reel 11,
When the chain terminal T wound around the terminal reel 11 is pulled along with the crimping operation by the terminal crimping machine 12, the terminal reel 11 is rotated by the pulling force, and the chain terminal T is sequentially and intermittently fed out. At this time, the terminal reel 11
Is provided with rotation resistance by the action of the compression coil spring 16b via the rotary plate 16a, so that the chain terminal T
The intermittent pulling operation does not cause excessive rotation and interlocking, and the adverse effects such as terminal deformation due to excessive extension of the chain terminal T are prevented.

On the other hand, when the terminal reel 11 is replaced, the used terminal reel 11 is slightly lifted to release the engagement between the edge of the center hole 11b and the locking step 16e. The terminal reel 11 can be easily removed from the support shaft 14 by pulling the support shaft 14 toward the distal end portion 14b.

In the above-described embodiment, an example is described in which the entire periphery is recessed as the receiving area 14c of the support shaft 14 and the diameter is set smaller than the outer diameter of the distal end portion 14b in order to form the locking step 16e. However, the receiving area 14c has the terminal reel 11
May be provided only on the upper surface. In the embodiment, the tip 14 b of the support shaft 14 is integrated with the support shaft 14, but another component having a diameter larger than the receiving area 14 c and smaller than the center hole 11 b of the terminal reel 11 is attached. It may be configured.
