Before and after the tongs plate axis 22 that pivots be positioned at the rear of combing cylinder 15 and below nipper framework 18.First end of nipper framework actuating arm 23 is fixed to tongs plate axis 22, to pivot with tongs plate axis 22 integral body.The rear end of nipper framework 18 is supported by second end of nipper framework actuating arm 23 pivotally by back shaft 23a.Nipper framework 18 is configured to rock back and forth, make bottom nipper 19 the front and back pivots (oscillating motion) of end by tongs plate axis 22 near detaching roller 16,17 with separate with detaching roller 16,17.
The structure of the drive part of detaching roller 16,17 is described now with reference to Fig. 2 A and 2B.Shown in Fig. 2 A, gear-box 24 (as the left and right directions of observing among Fig. 2 A) along the longitudinal direction is arranged on each end of combing machine.The axle 25,26 of detaching roller 16,17 is arranged to parallel to each other between gear-box 24.The end of axle 25,26 puts in the gear-box 24 and via the bearing (not shown) rotatably to be supported by gear-box 24.Gear 27,28 is respectively fixed to the end of axle 25,26, to rotate with axle 25,26 integral body.Gear 27,28 is formed has the identical number of teeth and identical diameter.
Two servo motors 29,30 are attached to each gear-box 24 to correspond respectively to axle 25,26.Servo motor 29,30 has motor drive shaft 29a, the 30a that puts in gear-box 24 respectively. Driven wheel 31,32 is respectively fixed to motor drive shaft 29a, 30a and rotates with integral body. Driven wheel 31,32 is formed with gear 27,28 has the identical number of teeth and identical diameter.Each gear-box 24 has and the idle pulley 33 of gear 27 and driven wheel 31 engagements and the idle pulley 34 that meshes with gear 28 and driven wheel 32 within it.Idle pulley 33,34 is formed has the identical number of teeth and identical diameter.Just, axle 25,26 drives via the gear train between motor drive shaft 29a, 30a and the axle 25,26, and this gear train comprises idle pulley 33,34. Axle 25,26 is with the rotation of identical with motor drive shaft 29a, 30a respectively rotary speed (rotary speed than be 1:1). Servo motor 29,30 controlled device (not shown) driven in synchronism are to rotate along forward direction or reverse direction.
The operation of the equipment of configuration as mentioned above will be described now.
Axle 25 is driven by two servo motors 29 at two axial end places.Axle 26 is driven by two servo motors 30 at two axial end places.Servo motor 29 and servo motor 30 are made axle 25,26 by driving synchronized with each other by driving synchronized with each other.In other words, axle 25,26 is driven by four motors.Therefore, if use the motor of identical performance, then can be with the torque drive detaching roller 16,17 of the moment of torsion that doubles prior art.Because axle 25,26 waves (front and back pivots) with at a high speed (for example 300rpm), so axle 25,26 has bigger torsion than the situations that axle 25,26 rotates along a direction with constant speed.Yet, because axle 25,26 two ends are driven by servo motor 29 and servo motor 30 respectively, thus the torsion that the amount of torsion is an axle 25,26 only to be produced in the driven structure of a side 1/4th.If axle 25,26 length is constant, then axle 25,26 resonant frequencies in the driven structure in two ends are higher than each resonant frequency of driven structure at one end of axle 25,26.Therefore, when the speed of combing machine increases, each rotary speed of 25,26 will be different with resonant frequency.
Present embodiment has the following advantages.
(1) need high moment of torsion to drive detaching roller 16,17.Motor inertia is by expression formula J=MD
2Expression, wherein M represents the quality of rotor, and D represents the overall diameter of rotor, and it equates substantially with the overall diameter of motor.Therefore, thereby rotate with high speed for the inertia that reduces motor allows motor, the overall diameter of motor preferably is manufactured to as much as possible little.In other words, motor torsional moment multiply by motor length by the motor overall diameter and determines.Therefore, suppose that overall diameter is identical, motor length is long more, and then motor torsional moment becomes big more.Yet in fact, owing to making reason, for example rotor clearance need be maintained at steady state value, so the length of motor can not surpass a certain limit.According to prior art, the axle of two detaching rollers is driven by two motors.On the contrary, according to the present invention, the two ends of axle 25,26 are driven by motor 29,30 respectively, make that axle 25,26 is synchronous.In other words, two axles 25,26 of detaching roller 16,17 are driven by four motors.Therefore, can be with the torque drive detaching roller 16,17 of the moment of torsion that doubles prior art.Therefore, under the situation of the size that does not increase independent servomotors 29,30, the detaching roller 16,17 of the high moment of torsion of needs can be with the speed drive more higher than prior art.
(2) typically, the distance between the central axis of pair of separated roller is as short as near 40mm.On the other hand, in order to drive the axle of detaching roller, need have high moment of torsion and with the motor of high speed operation.In this case, the distance of the overall diameter score of motor between the central axis of the axle of roller is big.Therefore, when the rotation of motor drive shaft is arrived the axle of detaching roller via gear transmission, under the configuration that the gear that is fixed to motor drive shaft and the direct geared of the axle that is fixed to detaching roller are meshed, the rotary speed of motor drive shaft can not be embodied as 1:1 with the ratio of the rotary speed of the axle of detaching roller.Yet the axle 25,26 of present embodiment drives via motor drive shaft 29a, the 30a of servo motor 29,30 and the gear train between the axle 25,26, and gear train comprises idle pulley 33,34.The driven wheel 31,32 that is fixed to motor drive shaft 29a, 30a has the identical number of teeth with the gear 27,28 that is fixed to axle 25,26.Therefore, even the distance between the central axis of the axle 25,26 of detaching roller 16,17 is as short as near 40mm, and the overall diameter of servo motor 29,30 is greater than the distance between the axis of axle 25,26, but the ratio of the rotary speed of motor drive shaft 29a, 30a and the rotary speed of axle 25,26 can be embodied as 1:1.In addition, size of motor (diameter) and rotary speed can be changed more neatly by the number of teeth that changes each gear in the gear train.
(3) because the ratio of the rotary speed of motor drive shaft 29a, 30a and the rotary speed of axle 25,26 is set to 1:1, therefore when the rotary speed of detaching roller 16,17 was changed by changing spinning conditions, the rotary speed of motor drive shaft 29a, 30a can easily be set.
(4) servo motor 29,30 is arranged such that motor drive shaft 29a, 30a are positioned at axle 25,26 tops, and comprises the axis of motor drive shaft 29a, 30a and the imaginary plane of axle 25,26 axis is oriented with respect to horizontal direction.Therefore, be provided so that with servo motor 29,30 this imaginary plane compared by the situation of horizontal orientation, can be easier to guarantee to hold the space of servo motor 29,30.
The invention is not restricted to above-described embodiment, but for example can be embodied as follows.
Axle 25,26 can be coupled to each other via gear.For example, as shown in Figure 3, connect gear 35 and can be set to and gear 27,28 engagements.In this case, axle 25,26 can rotate synchronously, because axle 25,26 is coupled to each other via gear, even if the synchronization accuracy between the servo motor 29,30 is low relatively.Connect the place, two ends that gear 35 preferably is arranged on axle 25,26, but can only be provided with at one end.
When axle 25,26 is coupled to each other via gear, can omit and driven wheel 31,32 meshed gears 27,28.For example, can be provided with discretely with gear 27,28, and the gear that connects with extra gears engaged can be set with axle 25,26 integrally rotated gears.Yet, use gear 27,28 easier.
The rotary speed of motor drive shaft 29a, 30a and axle 25,26 is than not needing to be 1:1.Just, the rotary speed of motor drive shaft 29a, 30a can be faster or slower than the rotary speed of axle 25,26.
Be used for the gear train that rotation with motor drive shaft 29a, 30a is delivered to axle 25,26 and needn't have idle pulley 33,34.What replace is that the gear that is fixed to motor drive shaft 29a, 30a can mesh with the direct geared that is fixed to axle 25,26.
