Detailed description of the invention
In order to further illustrate principle of the present invention and structure, existing by reference to the accompanying drawings to a preferred embodiment of the present invention will be described in detail.
Motor extending type material strip tension control mechanism of the present invention, comprises the line of slide rail being fixed on base plate 02, for floating drum 12 linear slide, is positioned at the tension buffer district of material strip; Be arranged on the floating drum 12 on line of slide rail 03, for the material strip in tensile buffer zone; Be arranged on the tension motor 09 on base plate 02, pull floating drum 12 to move linearly along line of slide rail 03 by flexible drive parts, for keeping the tension force of material strip; Position transduser, the positional value for detection of floating drum 12 on line of slide rail 03, and be sent to the control system of equipment; For the material strip buffer length of controlling in tension buffer district provides information.
The structure of motor extending type material strip tension control mechanism of the present invention is described as follows.
Fig. 1 is the front view of motor extending type material strip tension control mechanism embodiment of the present invention, and Fig. 2 is the birds-eye view of this embodiment, and Fig. 3 is the right elevation of this embodiment.
As shown in Figure 1, Figure 2 and Figure 3, line of slide rail 03 adopts straight-line guidance line rail, is fixed on base plate 02; Sliding panel 05 is arranged on line of slide rail 03, and two floating drums 12 are arranged on sliding panel 05.The axis of floating drum 12 is parallel with sliding panel 05 with base plate 02, vertical with line of slide rail 03.
Line of slide rail 03 belongs to linear class guide, other linear guide also can, other linear bearings, the similar linear guide such as slide rail of intersecting can adopt.
Tension motor 09 adopts servomotor, or stepper motor, Direct Current Motor, is arranged on base plate 02 by motor mount 10, and belt wheel 11 is fixed on the output shaft of tension motor 09.Flexible drive parts pulls with 07 top and connects on belt wheel 11, is then wound on belt wheel 11.Pull with 07 tail end and be connected on sliding panel 05.When the output shaft rotation of tension motor 09, be with 07 or receive or put by pulling of reeling on belt wheel 11.
Pull with 07 employing flat belt or the similar flexible Transmission such as rope, steel wire, or drive sliding panel 05 to slide along line of slide rail 03 by screw mandrel.
Position transduser is magneto strictive sensor, and the guide rod 01 of sensor is fixed on base plate 02 by permanent seat 08, and parallel with line of slide rail 03.The sensor block 06 of sensor is arranged on line of slide rail 03, and the sensor block 06 of sensor is fixedly connected with sliding panel 05 by drive block 04, moves linearly with sliding panel 05 guide rod 01 along sensor on line of slide rail 03.
The principle of work of motor extending type material strip tension control mechanism of the present invention is:
The moment of torsion that tension motor 09 is exported, is with 07 to be transformed into pulling force by pulling of coiling on the belt wheel 11 on motor output shaft, belt wheel 11, acts on and pulls on the sliding panel 05 connecting with 07 tail end.The floating drum 12 of installing on sliding panel 05, passes to material strip by pulling force, forms the tension force of material strip.The torque that tension motor 09 is exported, can be by the control system of equipment, does to adjust accurately.
Because dispensing speed or the material recovering speed of equipment do not mate with the speed of device processes material strip, in the time that the material strip in tension buffer district shortens, drive floating drum 12 to be moved to the left along line of slide rail 03 by sliding panel 05, pulling with 07 of being connected with sliding panel 05 pulls the belt wheel 11 on motor output shaft to put band rotation, discharge pulling of reeling on belt wheel 11 and be with 07, belt wheel 11 drives tension motor 09 to rotate backward by motor output shaft; Meanwhile, the sensor block 06 of the sensor being connected with sliding panel 05 is also moved to the left with sliding panel 05, and magneto strictive sensor detects a positional value of floating drum 12, and the floating drum of detection 12 these location informations is sent to the control system of equipment; Control system is according to the location information of floating drum 12, and the blowing motor of driving arrangement or rewinding motor are adjusted rotating speed, the material strip buffer length lengthening in tension buffer district.
In the time that the material strip in tension buffer district is elongated, tension motor 09 forward rotation, by the belt wheel 11 take-up rotations on motor output shaft, increase pulling of reeling on belt wheel 11 and be with 07, contraction pulls the straight length with 07, pulls the floating drum 12 of installing on sliding panel 05 and sliding panel 05 to move right along line of slide rail 03; Meanwhile, the sensor block 06 of the sensor being connected with sliding panel 05 also moves right with sliding panel 05, and magneto strictive sensor sends another positional value detecting to the control system of equipment; Control system, according to the new location information of floating drum 12, drives blowing motor or rewinding motor again to adjust rotating speed, shortens the material strip buffer length in tension buffer district.
No matter the motor output shaft of tension motor 09 is to rotate backward to discharge to pull to be with 07, or forward rotation is shunk the straight length pulling with 07, because the moment of torsion on tension motor 09 output shaft does not change, pull with 7 pulling force also constantly, so straining the pulling force of material strip, floating drum 12 also can not change.Material strip is all only subject to the impact of this constant pulling force and produces constant tension force at any state, thereby has realized the function of material strip tension control mechanism control material strip constant tension.
The principal feature of material strip tension control mechanism of the present invention is:
Adopt magneto strictive sensor, because magneto strictive sensor adopts maglev principle, the sensor block 06 of sensor does not contact with the guide rod 01 of sensor, can eliminate because of the impact of friction drag on tension force control, has reduced error.
The control system of equipment, adjusts the moment of torsion of setting tension motor 09 as required, and because the precision of tension motor 09 torque setting is high, the movement inertia of motor rotor and flexible drive parts is little, reaction is fast, thereby improves the control accuracy to material strip Tensity size.
Foregoing; it is only preferred embodiment of the present invention; not for limiting embodiment of the present invention; those of ordinary skill in the art are according to main design of the present invention and spirit; can carry out very easily corresponding flexible or amendment, therefore protection scope of the present invention should be as the criterion with the desired protection domain of claims.
