[0026]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

The index device 3 of the present invention is used, for example, as the index device 3 for the winding device 1 shown in FIG. Further, the index device 3 of the present invention differs from the conventional index device 3 shown in FIG.
Hereinafter, the difference will be described focusing on the index body 21.

FIG. 1 is a plan view of an index device 3 according to the present invention. FIG. 2 shows a front view of the index main body 21.

As shown, the index body 21
Is provided with parallel frames 41, 42 on both the left and right sides, sandwiches a pair of jig holding portions 43 between these frames 41, 42, and has the same number of jig holding portions 43 as the number of spindles 11 (this embodiment). In this embodiment, eight jigs 5 are held.
A rotary shaft 44 parallel to the jig holding portion 43 penetrates substantially at the center of the frames 41 and 42.
4 is fixed to frames 41 and 42.

Both ends of the rotating shaft 44 are respectively connected to column portions 23 and 24 of the index column 20 (not shown).
(See FIG. 9) is rotatably supported on the upper end side. The rotation of the rotary shaft 44 by 180 degrees causes the index body 21 to be inverted, the positions of the pair of jig holding portions 43 are switched, and the jig holding portions 43 arranged on the replacement side (upper side in the figure) are moved. The jig holding portion 43 arranged on the winding side (the lower side in the figure) and on the winding side are respectively moved to the replacement side. The rotation of the rotating shaft 44 is driven by the rotary cylinder 30 (not shown) within a range limited by the stopper device 31 (see FIG. 8).

The jig holding portion 43 has shafts 45 and 46 at both ends, and these shafts 45 and 46 are rotatably supported by frames 41 and 42 via bearings 46. Further, at both ends of the shafts 45 and 46 penetrating the frames 41 and 42,
The gears 51 and 52 are fixed respectively. These gears 5
1 and 52 mesh with adjacent gears 55 and 56, respectively, and these gears 55 and 56 mesh with gears 53 and 54 fixed to the outer periphery of the rotating shaft 44, respectively.
52 is associated with the gears 53 and 54, respectively. In this case, the gears 51 and 52 and the gears 53 and 54 have the same diameter. Note that the gears 55 and 56 are
The shafts 57 and 58 are fixed to the outer periphery of the shafts 57 and 58.
Are supported by the frames 41 and 42 via bearings 59, respectively.

With this configuration, when the rotating shaft 44 is rotated by 180 degrees for reversing the index body 21,
The gears 53 and 54 rotate integrally with the rotating shaft 44. At this time, these gears 5 and
The gears 51, 52 associated with the gears 3, 54 are gears 53, 54.
And the gears 53 and 54 and the gears 51 and 5
Since 2 has the same diameter, their rotation angles also match. For this reason, the jig holding unit 43 integrated with the gears 51 and 52 rotates 180 degrees similarly to the rotation shaft 44. Therefore, each jig 5 does not change its direction due to the inversion of the index body 21. That is, on the winding side, the mounting portion 5A is
The jig 5 facing the side (downward in FIG. 1) continues to have the mounting portion 5A facing the spindle side even if it moves to the replacement side.
The work holding portion 5B opposite to the mounting portion 5A faces the outside of the index device 3 (upward in FIG. 1). Similarly, the jig 5 in which the mounting portion 5B faces the outside of the index device 3 (upward in FIG. 1) on the replacement side does not change its direction on the winding side after the reversal, and the mounting portion 5A Will turn to the side. As described above, the jig 5 whose direction is not changed by the reversing operation is provided by the spindle 11 on the winding side.
The mounting portion 5A on the side can be mounted on the jig holder 12 as it is, while the replacement side can easily perform the replacement work on the work holding portion 5B facing the outside of the index device 3.

Next, a mechanism for holding the jig 5 in the jig holding section 43 will be described.

The jig holding section 43 has the following components:
The jig holder main body 61 shown in FIGS. 2 and 3 is provided. A plurality of (eight in the present embodiment) jig mounting holes 62 through which the jig 5 is mounted are formed in a line on the front surface of the jig holding portion main body 61, and at a predetermined position. A pair of long holes 6
4 are formed side by side vertically. Further, a pair of rails 63 are formed at the upper end and the lower end on the front side of the jig holding portion main body 61, and a jig fixing plate 71 shown in FIGS. .

The jig fixing plate 71 is a plate shorter in length than the jig holding portion main body 61, and the jig mounting hole 62 is provided at a position corresponding to the jig mounting hole 62 of the jig holding portion main body 61. The same number of substantially elliptical openings 72 are formed. These openings 72
Of these, the openings 72 at both ends extend to the ends of the jig fixing plate 71 to form open portions 73 and 74.

Further, a brim portion 75 is formed at a part of the edge of each opening 72. These flanges 75 are similarly provided in all the openings 72, and extend vertically from one end of each of the openings 72 to substantially the center of the opening 72. The ends of these flanges 75 are formed as tapered notches 76. As will be described later, the jig 5 is fixed to the index body 21 by being pressed by these flange portions 75.

A pair of pin holes 77 are formed in the jig fixing plate 71 at positions corresponding to the elongated holes 64.

FIG. 6 shows a jig holder 43 in which the jig fixing plate 71 is mounted on the jig holder main body 61. As shown in the drawing, an actuator (for example, an air cylinder) 80 is installed on the jig holding unit main body 61. A connecting member 82 is attached to the distal end of a rod 81 which is extendable and contractible in the horizontal direction of the actuator 80.
Are a pair of pins 83 in a pair of pin holes 77 of the jig fixing plate 71.
It is fixed at. The pin 8 of the jig holder main body 61
Since a long hole 64 is formed at a position corresponding to 3,
The pins 83 accommodated in the elongated holes 64 are free with respect to the jig holding portion main body 61. Therefore, when the actuator 80 operates, the jig fixing plate 71 moves horizontally along the rail 63 with respect to the jig holding portion main body 61. As a result, the flange 75 moves to the jig mounting hole 62 side, and the jig 5 in the jig mounting hole 62 is fixed.

FIG. 7 shows a state in which the flange 75 of the jig fixing plate 71 fixes the jig 5 in this manner. As shown in the figure, the jig fixing plate 71 moves to the left in the drawing due to the extension of the rod 81 of the actuator 80, and the flange 75 of the opening 72 moves the jig 5 attached to the jig mounting hole 62. The jig 5 is fixed by engaging with the outer periphery of a groove 5C formed in a part of the outer periphery of the jig 5. The notch formed at the end of the flange 75 allows the flange 75 to be smoothly fitted into the groove 5C.

Next, the operation will be described.

The index device 3 located at the reference position
First, the work 4 is moved to the replacement position, and the work of replacing the work 4 is performed. In this case, the work of replacing the work 4 is performed by pressing the work 4 into a split portion formed in a notch at the tip of the work holding portion 5B and supporting the work 4 with elastic force in the work holding portion 5B of the jig 5. In addition, the work is performed by removing the work 4 from the split portion. However, since the work holding portion 5B faces the outside of the index device 3, that is, the worker side, the worker (or work machine) can be viewed from the front. The work of replacing the work 4 can be easily performed. In this case, the mounting portion 5A of the jig 5 held by the jig holding portion 43 is
Facing the side.

Next, the index device 3 is moved to the mounting position, and receives the jig 5 for holding the already wound work 4 to the jig holding portion 43 on the winding side. Thereafter, the index device 3 returns to the reference position, and the index device 3 is reversed by the rotation of the rotary shaft 44 by 180 degrees driven by the rotary cylinder 30. In this case, in the present invention, the gears 51, 5 fixed to the shafts 45, 46 at both ends of the pair of jig holding portions 43 are provided.
2 rotates integrally with the gears 51, 52 of the same diameter on the outer periphery of the rotating shaft 44 via the gears 55, 56, so that the pair of jig holders 43 also inverts themselves by 180 degrees, and eventually, the index body 21. The direction of the jig 5 is kept the same after the inversion. For this reason, the mounting portion 5A of the jig 5 always faces the spindle 11, and if the indexing device 3 is moved to the mounting position on the spindle 11, the mounting portion 5A is inserted into the jig holder 12 as it is. .

The mounting portion 5A of the jig 5 thus inserted into the jig holder 12 is locked to the jig holder 12 by a locking mechanism such as a ball plunger. In this state, the actuator 80 is operated, and the jig fixing plate 71 is operated.
After releasing the engagement between the flange portion 75 and the groove 5C of the jig 5,
When the index device 3 is retracted to the reference position, the jig 5
Escapes from the jig mounting hole 62 and is delivered to the spindle 11 side.

After the jig 5 is transferred to the spindle 11 in this way, the work 4 held by the jig 5 is wound. During this winding operation, the index device 3 is moved to the reference position. Then, the jig 5 for holding the already wound work 4 is disposed on the replacement side, and then returns to the replacement position, and the work 4 is replaced on the jig 5.

As described above, the replacement work of the work 4 and the winding work on the work 4 are continuously performed. In the present invention, the jig 5 held by the index body 21 is replaced. Regardless of the side or winding side,
The mounting section 5A is moved to the spindle 11 side and the work holding section 5
Since B is disposed facing the opposite side of the spindle 11 (ie, the operator side), inconvenience occurs not only in mounting the jig 5 on the jig holder 12 but also in replacing the work 4 on the jig 5. Instead, the efficiency of the work of replacing the work 4 can be significantly improved.

[0046]

According to the first aspect of the present invention, the index device is moved to the replacement position, and the work is attached to the jig held by the jig holding portion arranged on the replacement side. The jig holding portion holding the jig is turned over and arranged on the winding side, and the index device is moved to the mounting position to mount the jig on the spindle. In this case, the jig holding portion is also turned 180 degrees with respect to the index body with the 180-degree reversal of the index device, so that the mounting portion of the jig always faces the mounting position side, While the spindle can be directly mounted on the spindle, the mounting part and the work holding part are always facing the replacement position side.Therefore, during the replacement work, the work holding part faces the worker or the front of the working machine, and the work is stopped. Can be easily performed, and the efficiency of the operation is significantly improved.

According to the second invention, the first gear fixed to the shaft of the jig holding portion and the second gear having the same diameter as the first gear fixed to the rotating shaft of the index body are: Since the index body is inverted directly or indirectly, and the second gear rotates 180 degrees, the first gear also rotates 180 degrees, and the jig holder rotates 180 degrees with respect to the index body. .

According to the third aspect of the present invention, the jig fixing plate is moved by driving the actuator, and the jig can be easily engaged and disengaged by the collar portion. Delivery of the ingredients is done smoothly. In particular, when a plurality of jig mounting holes are provided and a plurality of jigs are held in the jig holding portion, locking and releasing of these jigs can be performed simultaneously by one actuator.
