Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a setting jig used for inserting and fixing a reel-wound tape roll onto a rotating support shaft.

(Prior Art) Conventionally, as a structure for fixing a tape roll to a vertical or horizontal rotating shaft using this type of setting jig, for example, as shown in FIG. One end of the reel 1a is brought into contact with a stopper 10 fixed to the rotation support shaft 2 to position it, and a sleeve-shaped setting jig 21 is attached to the free end side of the rotation support shaft 2. There is a structure in which the setting jig 21 is fixed to the rotating shaft 2 with a set bolt 22 so that the protrusion 23 provided on the end surface of the set jig 21 is pressed against the other end of the reel 1a.

In addition, as shown in FIG. 6, the setting jig 21
a pressing ring 21a equipped with a protrusion 23 that fits into the end surface of the reel 1a; a coil spring 21b that presses the pressing ring 21a toward the reel;
A structure is known in which the spring 21b is configured with a collar 21c that receives the spring 21b, and the collar 21c is externally fitted onto the rotary support shaft 2 so as to be adjustable in its screw movement, and is fixed with a set bolt 22.

(Problem to be solved by the invention) However, in the structure shown in Fig. 5, the setting jig 2
While pressing 1 manually against the end face of reel 1a,
Since the set bolt 22 must be operated, a considerable amount of force is required for the operation, and if the reel pressing force is insufficient, there is a risk that the tape roll 1 will slip with respect to the rotational support shaft 2.

On the other hand, in the structure shown in Fig. 6, the spring 2
Since the pressing ring 21a is pressed toward the reel 1a through the reel 1b, there is no risk of insufficient reel pressing force. color 21
It is necessary to attach and detach the collar by screwing the collar, and it takes time and effort to rotate the collar, resulting in low workability. Moreover, the structure is relatively complicated, and the rotating support shaft 2 must be formed with a male thread.

The present invention has been developed in view of the above-mentioned circumstances, and an object of the present invention is to prevent insufficient reel pressing force and to allow the setting jig to be easily attached and detached when attaching and detaching the tape roll. With the goal.

(Means for Solving the Problems) In order to achieve the above object, the setting jig according to the present invention includes a jig body that can be fixed by being inserted into a rotating shaft, and a jig body that is screwed into the jig body. The movable ring is provided with a protrusion that engages with the end face of the reel, and the movable ring is provided with a protrusion that engages with the end face of the reel. The mating direction was set to be a direction in which the movable ring rotates in the tape feeding direction and thereby spirally moves toward the reel.

(Function) When loading a tape roll, the tape roll and setting jig are sequentially inserted into the rotational support shaft, and the reel end of the tape roll is positioned against the stopper of the rotational support shaft, and the protrusion of the movable ring is inserted into the reel. Fix the jig main body to the rotating shaft so that it lightly contacts the end face.

When tape feeding operation begins in this state, the tape roll initially rotates relative to the rotational support shaft, but as the tape roll rotates, the movable ring rotates together with the reel, and the movable ring rotates in unison with the reel. When the movable ring rotates in the tape payout direction relative to the jig body, the movable ring moves toward the reel and the reel pressure is strengthened.Finally, the movable ring becomes unable to move, and the tape roll and rotation support are The shaft is integrated and rotates.

When removing the reel from the rotating shaft for tape replacement, it is sufficient to release the fixation of the jig main body to the rotating shaft and pull it out as is.

(Example) Fig. 1 is a vertical side view showing an example of a tape roll fixing structure using a setting jig according to the present invention, Fig. 2 is an exploded perspective view of the setting jig, and Fig. 3 is a band brake. FIG. 4 is a front view of the movable ring of the setting jig as seen from the tape roll side.

In these figures, a rotating support shaft 2 on which a reeled tape roll 1 is mounted is supported on a frame 3 in a horizontal or vertical direction via a pair of bearings 4, 4. This rotation support shaft 2 has a bearing 4
It consists of a solid support shaft body 2a supported by a solid support shaft body 2a, and a cylindrical tape attachment shaft 2b externally fitted and fixed on the free end side of the solid support shaft body 2a.The support shaft body 2a is equipped with a band brake 5 and an electromagnetic brake 6. It is being The band brake 5 is, as shown in FIG. It provides rotational braking force to suppress overrun when feeding the tape.

Further, the electromagnetic brake 6 is configured to perform a braking action only when the extension is stopped.

Next, the structure for fixing the tape roll to the rotating support shaft 2 will be explained.

A ring-shaped stopper 10 is fixed in the middle of the tape attachment shaft 2b, and the tip of the reel 1a of the tape roll 1 is received and positioned by this stopper 10, and the free end of the tape attachment shaft 2b is is a setting jig 11 for fixing the tape roll
is installed.

This setting jig 11 consists of a jig main body 11a that is externally fitted onto the tape attachment shaft 2b and fixed by a set bolt 12 with a handle, and a movable ring 11b that is externally fitted and screwed onto the jig main body 11a. Projections 13 that engage with the end surface of the reel 1a are provided at four locations in the circumferential direction on the end surface of the movable ring 11b. When the tape roll 1 rotates in the tape feeding direction A, the protrusion 13
It is formed into a sawtooth shape that is sharp in the direction opposite to the feeding direction A so that it can easily engage with the end surface.
In addition, the outer peripheral surface of the jig main body 11a and the movable ring 11
The threaded portions 14a and 14b formed on the inner circumferential surface of b are
When the movable ring 11b rotates in the tape feeding direction A with respect to the jig main body 11a, the movable ring 11b spirally moves toward the reel 1a side.
The screwing direction is set.

According to the above configuration, when the tape roll 1 is rotated by the tape feeding force, the movable ring 11b engaged with the reel 1a via the protrusion 13 rotates in the same direction, and accordingly. By spirally advancing against the jig main body 11a that is free from the jig main body 11a, the reel pressing force of the movable ring 11b is strengthened, and the tape roll 1 is reliably integrated with the rotation support shaft 2.

(Effects of the invention) As explained above, according to the invention, there is no need to apply a strong reel pressing force from the beginning when installing the setting jig on the rotating support shaft. The reel pressing force is automatically strengthened to ensure integration with the rotating spindle, and the jig can be attached and removed simply by fixing and unfixing the jig body to the rotating spindle. This can be done easily and quickly, and the work efficiency when replacing tape rolls is greatly improved.
