Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a TAB (Tape A)
The present invention relates to a reel assembling device for detachably fixing a reel around which a tape is wound, to a reel shaft which is rotated by a motor as a drive source, in an assembling cylindrical portion at the center thereof. .

[0002]

2. Description of the Related Art For example, a TAB inspection machine sequentially sends a TAB wound on a reel attached to a reel shaft to an inspection section, and inspects whether the patterns provided on the TAB are open or short-circuited. But the TA
B has various widths, and the reel around which the TAB is wound must also correspond to the TAB. Therefore, the reel must be removably mounted on the reel shaft.

Conventionally, a reel is assembled to a reel shaft at an installation cylinder located at the center thereof, and then the screws are tightened with a tool.

Therefore, the operation of attaching and detaching the reel to and from the reel shaft is complicated.

The present invention has been made with a view to such a conventional example, with the object of providing an apparatus capable of smoothly attaching and detaching a reel to and from a reel shaft.

[0006]

A reel mounting device for removably fixing a reel around which TAB or other tape is wound to a reel shaft which rotates by a motor as a driving source, in a mounting cylindrical portion thereof. On the peripheral side of the cylindrical reel shaft, an elongated hole whose axial direction is elongated is provided, and the elongated hole protrudes from the peripheral side of the reel shaft and presses against the inner surface of the mounting cylinder portion of the reel. The fixing piece is engaged, and the truncated cone-shaped pieces slidingly in contact with the tapered edges provided at both ends of the fixing piece are housed in the reel shaft so as to face each other, and the pieces are penetrated and the shaft of the reel shaft is penetrated. Along with an operation shaft arranged on a line, a first spring that is interposed between the pieces and urges the pieces in the separating direction is wound and assembled, and a spring receiver is engaged with an open end of the reel shaft, This spring A second spring having an elastic force greater than that of the first spring is interposed between the first spring and one of the pieces, wound around the operation shaft and assembled, and a spring holder is reeled against the bias of the second spring. An operation lever press-fitted into the shaft is rotatably pivotally attached to one end of the operation shaft protruding from an open end of the reel shaft through a spring receiver, and the other one of the pieces of the operation shaft penetrates. At the other end, the receiving means of the other piece is attached as a basic means, and a resilient rod in the form of a broken ring whose outer surface of the fixing piece contacts the basic means is wound around the reel shaft. This is to add the rotated point.

[0007]

When the reel is assembled at a predetermined position on the reel shaft such that the reel shaft penetrates the assembling cylinder, and the operating lever is operated to press the spring retainer in the direction of the reel shaft, the spring retainer is moved to the second position. It is pressed into the reel shaft against the bias of the second spring (indirectly also against the bias of the first spring). At this time, the second spring has a stronger elastic force than the first spring. Therefore, the second spring interposed between the pair of pieces whose movement along the operation axis is restricted is reduced, and therefore, the pieces come close to each other while sliding on the tapered edge of the fixing piece, and the fixing piece is attached to the reel shaft. The fixing piece is pressed outward in the circumferential direction, the fixing piece is pressed against the inner surface of the mounting cylinder portion of the reel, and the reel is fixed to the reel shaft.

Further, when the fixing piece attempts to press the inner surface more than necessary due to the small inner diameter of the assembling cylindrical portion of the reel, the pressing force acts reactively on the second spring through the bridge. The second spring contracts and reduces the pressing force of the piece against the inner surface, thereby preventing damage to the reel (generally made of synthetic resin).

When the operating lever is returned to the original position, the respective members return to the original position by the action of the first and second springs, and the fixing piece returns to the original position by the action of the resilient rod shaped like a broken circle. I do.

1 is a sectional view, FIG. 2 is a sectional view taken along line XX of FIG. 1, and FIG. 3 is a sectional view showing a state in which the reel is fixed. 4 is a sectional view taken along line YY of FIG. 3, and FIG. 5 is a front view.

In FIG. 1, reference numeral 1 denotes a cylindrical reel shaft which is connected to a motor 3 via a bearing 2 and rotates using the motor 3 as a drive source. A reel 7 which is fitted to the key 4 in an engagement groove 6 formed on the inner surface of the assembling cylindrical portion 5 and is further combined with the key shaft 4 so as to penetrate the reel shaft 1 by a fixing device 8. And the TAB wound around the reel 7 is led out from the reel 7.

When the reel 7 is combined with the reel shaft 1, the positioning ring 9 is previously moved and fixed at an appropriate position along the axial direction of the reel shaft 1 so as to correspond to the size (width) of the reel shaft 7. The reel 7 is brought into contact with the positioning ring 9 to determine a reel mounting position along the axial direction of the reel shaft.

The fixing device 8 operates the operation lever 10 to cause the stationary piece 11 to protrude from the peripheral side of the reel shaft 1, and the outer surface 11 a of the stationary piece 11 to the inside of the mounting cylindrical portion 5 of the reel 7. , And the reel 7 is detachably fixed to the reel shaft 1.

The stationary piece 11 constituting the fixing device 8
Are engaged with elongated holes 12 provided on the peripheral side of the reel shaft 1 with the axial direction of the reel shaft elongated, and are arranged at equal intervals on the peripheral side of the shaft 1 in three directions. The shaft 1 is assembled to the shaft 1 by means of a resilient rod 21 in the form of a missing circle that is wound around the shaft 1 while engaging with the peripheral edge 1 a and the groove 13 formed in the outer surface 11 a of the stationary piece 11.

In a portion where the elastic rod 21 overlaps the key 4, a groove is provided inside the key 4, and the elastic rod 21 is wound around the reel shaft 1 through the groove as described above.

At both ends in the longitudinal direction of the stationary piece 11, that is, along the axis of the reel shaft 1 (on the inner side surface corresponding to the outer side surface 11a), tapered edges a are provided so as to chamfer both ends. A pair of truncated cone-shaped pieces 14, 14 'slidingly contacting the edge a are housed in the reel shaft 1 so as to face each other, and the piece 1 is placed on the axis of the shaft 1.
4 and 14 ′, an operation shaft 15 penetrating therethrough,
5, the pieces 14, 1 'are interposed between the pieces 14, 14'.
The first springs 16 for urging the 4 'in the separating direction are wound and assembled.

One end of the operating shaft 15 through which the one piece 14 penetrates is provided between the spring receiver 17 and the piece 14 so as to be partially wound around the spring receiver 17. The reel lever 1 is protruded from the open end of the reel shaft 1 through a second spring 18 having an elastic force greater than that of the first spring 16.
Are rotatably pivoted by pins 19.

The operating lever 10 has a straight edge portion 10a and a curved edge portion 10b arranged adjacent to each other in the direction of rotation about the pin 19, and when the straight edge portion 10a is in contact with the spring receiver 17, When the curved edge portion 10b contacts the spring receiver 17 without acting on the pieces 14, 14 ', the spring receiver 17 is pressed,
As a result, the second spring 18 to the first spring 1
The pieces 14 and 14 'are arranged to be close to each other via 6.

The spring receiver 17 is engaged with the open end of the reel shaft 1 and movably assembled to the operation shaft 15 so as to be immersed in the reel shaft 1 as shown in FIG. It is not always necessary to combine with the shaft 1 so as to be immersed.

A nut is screwed into the other end of the operating shaft 15 through which the other piece 14 'passes, thereby forming a receiving member 20 for the piece 14'. The movement of the piece 14 'due to the urging is controlled.

Thus, from the state shown in FIG.
Is rotated about the pin 19 as a fulcrum, the curved edge portion 10a replaces the direct edge portion 10a of the operation lever base portion which has been in contact with the spring 17.
Since b comes into contact with the spring support 17, the spring support 17 is pressed by the operation lever 10. At this time, the first spring 16 has a relatively smaller spring force than the second spring 18, so that the pressing operation is , Acts on the piece 14 via the spring support 17 and the second spring 18, and as a result, the pair of pieces 14, 14 ′ move in a direction approaching each other against the bias of the first spring 16. , Pieces 14, 14 '
The stationary piece 11 is pressed in a direction in which the stationary piece 11 protrudes from the shaft so as to slide on the tapered edge a of the stationary piece 11 so as to push and spread the stationary piece 11 with respect to the shaft 1, so to speak.
As a result, the stationary piece 11 projects from the long hole 12, that is, from the peripheral side of the reel shaft 1, against the bias of the elastic rod 21 and presses the inner surface of the mounting cylinder 5 of the reel 7, and the reel 7 It is fixed to the shaft 1.

When the operating lever 10 is rotated to bring the right edge 10a into contact with the spring receiver 17, the members return to their original positions by the action of the springs 16, 18 and the elastic rod 21.

The second spring 18 functions in accordance with the inner diameter of the reel 7. When the pieces 14, 14 'press the stationary piece 11 against the inner surface of the reel 7, the second spring 18 contacts the inner surface of the reel 7. When an unnecessarily large load is to be applied, the second spring 18 contracts to reduce the pressing force of the pieces 14 and 14 'against the stationary piece 11, thereby preventing the reel 7 from being damaged.

In the figure, reference numeral 32 denotes a screw 33
The shaft 32 is the coupling 3
4 is connected to the motor 3.

Although the embodiment shows a case where a TAB reel is mounted on a reel shaft 1 provided in a TAB inspection machine, the present invention can be applied to a case where a projection tape or other reels are mounted.

Since the present invention is configured as described above, the operation of attaching and detaching the reel to and from the reel shaft is performed smoothly.
In addition, it is possible to provide a reel assembling device capable of securely fixing.
