[0006]

In the case of the first aspect, the sub-fixed stage is moved by the cylinder drive in the direction in which the core is mounted, that is, in the left direction shown in FIG. By this movement, the slave taper core is inserted into the core of the core. Further, the protrusion of the slave stopper of the slave fixing base presses the core to the left as shown in FIG. 1 through a slave groove formed on the outer periphery of the core. The core is fixed by being inserted into the core of the core.

On the other hand, when detaching the core, the cylinder rod is moved in the opposite direction, that is, in the right direction shown in FIG. By this movement, the sub-fixing base moves in the same direction, and the sub-taper core formed at the tip of the sub-rotation shaft is separated from the core. Also, the protrusion of the slave stopper abuts the slave groove side wall to move the core in the same direction as the slave fixing base, and further the movement of the core causes the main stopper to abut the side wall of the main groove,
The main taper core is detached from the core of the opposite core, and the core is detached from the chuck device.

In the case of the second aspect, the sub-fixed stage is moved by the cylinder drive in the direction in which the core is mounted, that is, in the left direction shown in FIG. By this movement, the slave taper core is inserted into the core of the core. Further, when the slave fixing base further moves leftward, the core is moved leftward by the slave taper core, and the main taper core formed at the tip of the main rotation shaft is inserted into the core of the core and the core is fixed. .

When attaching and detaching the core, the cylinder rod is moved in the opposite direction, that is, to the right as shown in FIG. By this movement, the sub-fixed table moves in the same direction. In this case, if the fitting force between the slave taper core and the core is weaker than the fitting force between the main taper core and the core, the slave taper core formed at the distal end of the slave rotation shaft separates from the core first. At the same time, the pin fitted to the sub-fixing base also moves rightward at the same time. Since the protrusion of the stopper is in contact with the slave groove, the position of FIG. 3 is maintained until the slave fixing base moves rightward by S / 2 or more. When the cylinder rod moves to the right by S / 2 or more, the stopper is also moved by being pulled by the pin fitted to the sub-fixed table. Since the stopper is fitted in the sub groove of the core, the core is moved rightward together with the stopper, and the core and the main taper core are also separated.

A groove 57 is formed at the end of the core 40 in the circumferential direction in the longitudinal direction, and a protrusion 58 of a slave stopper 59 fixed to the slave holder 51 is inserted into the slave groove 57. The sub-fixing table 51 is connected to a rod 60 of a reciprocating feed screw mechanism, a hydraulic or air cylinder mechanism. The rod 60 is slidable in the axial direction by a guide table 62. In FIG. 1, an auxiliary cylinder 51 is
Is reciprocated, and the stroke S of the air cylinder 61 is controlled by the main stopper 45 and the core 40 as shown in FIG.
And S / 2 between the secondary stopper 59 and the core 40.

FIG. 2 is a view of the projection 58 as viewed from the direction indicated by arrows A to A in FIG. The projection 58 is formed in a U-shaped cross section so that the empty or full core 40 can be placed thereon. Also, the protruding portion 58 is the core 4
The groove 40 is formed to have the same size as the outer diameter of the slave groove 57, and has a function as a stopper when the core 40 moves S / 2. The protrusion 44 has the same shape.

Next, the operation of the first embodiment constructed as described above will be described.
Is moved rightward as shown in FIG. 1, the core 40 is in a detached state, and the wound core is removed. Then, the new core 40 is placed on the protrusions 44 and 58 and the air cylinder 61 is mounted.
Is driven to move the rod 60 to the left in FIG. Due to the movement of the rod 61, the slave fixing base 51 also moves in the same direction, and the slave taper core 55 is inserted into the core of the core 40. The slave stopper 59 also moves in the same direction, and the protrusion 58
7 is moved to just before the left end. By moving the core 40 to the left, the main taper core 38 is inserted into the core on the opposite side of the core 40, and the core 40 is fixed.

On the other hand, when the core 40 is detached, the operation is as follows.
The air cylinder 61 is actuated in the opposite direction to move the rod 60 rightward. Due to this movement, the sub-table 51 moves rightward, and the sub-stopper 59 attached to the sub-table 51 also moves rightward. Since the taper fitting has a bite, when the slave taper core 55 moves rightward, the tapered core with a weak bite is detached first. First, when the slave taper core 55 comes off first, the core 4
0 is engaged with the main taper core 38 and is stationary. Accordingly, the projection 58 of the slave stopper 59 contacts the right side of the slave groove 57, and moves the core 40 rightward. Therefore, the main tapered core 38 is separated from the core of the core 40. By this operation, the core 40 is separated from each tapered core.

On the other hand, when the main taper core 38 is detached first, the core 40 and the slave taper core 55 move rightward while being engaged. At this time, when the core 40 moves by 1/2 S, the protrusion 44 of the main stopper 45 is moved to the main groove 42 of the core 40.
Abuts the side wall. Further, when the slave taper core 55 moves to the right, the core 40 cannot follow, and thus separates. Therefore, the core 40 separates from each tapered core.

Next, in the second embodiment shown in FIG. 3, the first embodiment shown in FIG.
The difference from the embodiment will be described.
A groove 57 is formed at the end of the stopper 5 in the longitudinal direction in the circumferential direction.

The rod 60 is slidable in the axial direction by a guide table 62, and a guide table lid 63 having a shape for receiving a stopper 59 'is attached to the guide table 62. In FIG. 3, the sub-fixed table 51 is reciprocated using the air cylinder 61, and the stroke S
Is the distance S between the stopper 59 'and the pin 56 as shown in FIG.
/ 2 and a gap S / 2 between the end face of the stopper 59 'and the guide base lid 63.

FIG. 4 shows a projection 58 (a view as seen from arrows B to B in FIG. 3). The projection 58 is formed in a U-shaped cross section so that an empty or fully wound core 40 can be placed thereon. . FIG. 5 shows a stopper 59 '.
Is a view as viewed in the direction of arrow C, and a long hole for providing a gap of S / 2 is formed in the stopper 59 '.

Next, the operation of the second embodiment shown in FIG. 3 will be described. When the rod 60 of the air cylinder 61 is moved rightward as shown in FIG. Remove the finished core. Then, the new core 40 is placed on the protrusion 58 and the air cylinder 61
To move the rod 60 to the left in FIG. Due to the movement of the rod 61, the slave fixing base 51 also moves in the same direction, and the slave taper core 55 is inserted into the core of the core 40. Further, by moving the core 40 to the left, the main tapered core 38 is inserted into the core on the opposite side of the core 40, and the core 40 is fixed.

On the other hand, the action when detaching the core 40 is as follows.
The air cylinder 61 is actuated in the opposite direction to move the rod 60 rightward. With this movement, the sub-table 51 moves rightward, and the stopper 59 'mounted on the sub-table 51 also moves rightward. Since the taper fitting has a bite, when the slave taper core 55 moves rightward, the tapered core with a weak bite is detached first. First, when the slave taper core 55 is detached first, the stopper 40 'stops moving because the pin 56 only moves in the elongated hole until S / 2, and the stopper does not operate. Remains. Next, when the secondary fixing base 51 moves by S / 2 or more, the stopper 59 '
Is moved rightward by being pulled by the pin 56. Therefore, the protrusion 58 of the stopper 59 'abuts on the right side of the slave groove 57, and moves the core 40 rightward. Therefore, the main tapered core 38 is separated from the core of the core 40. By this operation, core 4
0 departs from each tapered core.

On the other hand, when the tapered core 38 is detached first, the core 40 and the slave tapered core 55 move rightward while being engaged. At this time, when the slave fixed base 51 moves by 1 / 2S, the end face of the stopper 59 'comes into contact with the guide base lid 63. Further, when the sub-fixing base 51 moves rightward, the stopper 59 'cannot move. Therefore, the sub-groove 57 of the core 40 which bites into the sub-rotating shaft 50 and moves rightward, and the protrusion 58 of the stopper 59' are formed. The core 40 is pushed away from the slave shaft 50. Therefore, the core 40 separates from each tapered core.
