The specific embodiment
Embodiment
Below, embodiments of the invention are described.
What Fig. 1 showed is the winding core fixing device of shears, is the device of fixing a plurality of winding cores 1, has a plurality of retainers 2.Retainer 2 is a ring-type, is set on the winding off spindle 3, and is provided with at interval at direction of principal axis, by bearing 4 rotatable supports.
In addition, in each retainer 2, promptly on the outer peripheral face of retainer 2, be formed with many loading chutes 5, as shown in Figure 2, have many pins 6 to be arranged on around the circumference of winding off spindle 3, and be positioned at loading chute 5 with angle intervals.The axle of pin 6 stretches along the direction of principal axis of winding off spindle 3, and its two ends are fixed and are supported on the retainer 2.So, by winding off spindle 3, bearing 4 and retainer 2 supporting pins 6.In addition, many fulcrums 7 are housed in loading chute 5, fulcrum 7 stretches along the hand of rotation of winding off spindle 3, supports and makes and respectively sell 6 and can shake, and gives prominence to the both sides at each pin 6.In addition, a plurality of swiveies 8 are housed in loading chute 5, swivel 8 is made of cylinder, is set at the two ends of each fulcrum 7, and is rotatably fixing.Use gear on swivel 8, this gear rotatably is fixed on the fulcrum 7.
In addition, this device has a plurality of cylinder bands 9.Cylinder band 9 is same with the disclosed structure of the public clear 60-30621 communique of spy, for ring-type, be set between each retainer 2, chimeric and fixing with the periphery of winding off spindle 3.In each cylinder band 9, the structure of the piston 10 of packing in a plurality of axial endoporus is also the same with structure in the above same communique.Therefore, fluid pressures such as air are supplied with each cylinder band 9, make the end joined of piston 10 and retainer 2 and push down.
So, in this device, each winding core 1 axially being provided with on the circumference of winding off spindle 3 at interval, its position is corresponding mutually with adjacent retainer 2.Then, when driving winding off spindle 3, when making its rotation, give cylinder band 9 and piston 10 with the torque transmission by drive motor.By piston 10 frictional transmission torque with retainer 2, make retainer 2 rotations, each fulcrum 7 is that the center is shaken with its pin 6 simultaneously, the inner peripheral surface of winding core 1 is pushed down and entered to swivel 8 in the swivel 8 at fulcrum 7 two ends.
For example, when winding off spindle 3 and retainer 2 were pressed among Fig. 2 right-hand revolution, each fulcrum 7 shook for anticlockwise direction among middle mind-set Fig. 2 with pin 6.Therefore, as shown in Figure 3, the inner peripheral surface of winding core 1 is pushed down and entered to the swivel 8 of the right-hand member in the swivel 8 at fulcrum 7 two ends.Like this, pin and fix winding core 1.On the contrary, when winding off spindle 3 and retainer 2 were pressed among Fig. 2 anti-clockwise rotation, each fulcrum 7 shook for clockwise direction among middle mind-set Fig. 2 with pin 6.Therefore, the inner peripheral surface of winding core 1 is pushed down and entered to the swivel 8 of left end on the fulcrum among Fig. 37.Like this, pin and fix winding core 1.
