Description
Technical field
The utility model relates to the drive unit of industrial computer embroidery machine, specifically is meant a kind of tabouret drive unit that is applied to the hybrid feedback drive controlling of computer embroidering machine.
Background technology
Traditional bull formula computer embroidering machine tabouret driving method can be divided into two kinds of driven by servomotor and step motor drive.Tabouret is to drive belt pulley through motor shaft; The drive division assemblies of the many groups of series connection, transmission of power to tabouret, thereby drive tabouret, press the style program point that computer generates and move.This driving method of two kinds respectively has merits and demerits.Driven by servomotor is closed-loop control, and the motion control precision is high, but price is also higher relatively.And stepper motor and driving are open loop control, and the motion control precision is low to cause step-out etc. with receiving external interference easily, and embroidery pattern is walked, influence embroidery quality, but its price is also relatively cheap.
Multi-head computerized embroidery technique and bull formula computerized embroidery machinery, as shown in Figure 1, embroidery machine is provided with a plurality of heads 2; Warp tube 1 provides line on the embroidery usefulness, reaches the standard grade and passes the embroidery pin 4 that is installed on the shank case 3, embroiders pin band embroidery line and pumps on cloth; The bottom line with rotating shuttle 6 supply of reaching the standard grade twines mutually and generates chain knot; And the formation of embroidery style is because main frame 5 is placed in the syncmotor of X and Y direction and drives, and cooperation is embroidered the motion of pin and formed the style that is generated by computer.
Bull formula computerized embroidery machinery, its tabouret places on the drive division of X and Y axle, directly comes drive pulley by synchronous servo motor or stepper motor, drives belt and belt clamp on the drive division, drives to place the tabouret on the platen to move back and forth.No matter on servo or step drive device, as long as being set, suitable applications writes with relevant computer program, just can drive the motion of tabouret in the parameter combinations of embroidery machine.
As shown in Figure 2, what the driving principle of servomotor or stepper motor was maximum is respectively that SERVO CONTROL is closed-loop control; Pulse signal is all detected by built-in encoder, feeds back to controller to control information, and exports tabouret again to after making corresponding adjustment; Therefore; As disturbed by external force in driving, final output quantity all can be revised, thereby accuracy is high.On the contrary, stepping is controlled to be open loop control, and pulse signal does not all have through detection and just exports controller to, lets its motion tabouret.Therefore, even if there is not external force to influence, if motor has the step-out phenomenon, its output just cannot be revised, and causes that finally style walks, embroiders phenomenons such as line skew, has influenced the embroidery quality widely.
The utility model content
The utility model purpose just provides a kind of hybrid tabouret drive unit of realizing the peripheral servo closed-loop control of embroidery machine, the advantage of mixing SERVO CONTROL and stepping control, raising embroidery quality and power output, having strengthened the cost performance of machine.
The utility model can be realized through following technical scheme:
The utility model discloses a kind of hybrid tabouret drive unit; Comprise stepper motor and tabouret; Described stepper motor produces circuit with pulse code and is connected; This pulse code produces circuit and includes wave filter, pwm signal generator, amplifier, and described wave filter, pwm signal generator, amplifier are continuous in proper order.
Described stepper motor also is connected with rotary encoder, and rotary encoder is connected with servo CPU.
Described rotary encoder is photo-electric angle sensor and semiconductor angular transducer.
Described rotary encoder is picked up the position of measuring and the error amount of speed, handles the FEEDBACK CONTROL of back as position and speed with servo CPU.
Described pulse code produces circuit and also includes position signalling comparator, positioner, rate signal comparator, speed control; One input of described position signalling comparator is connected with wave filter; Another input is connected with servo CPU; The output of position signalling comparator is connected with positioner; One input of rate signal comparator is connected with positioner, and its another input is connected with servo CPU, and the output of rate signal comparator is connected with the pwm signal generator.
The hybrid tabouret drive unit of the utility model is basic original paper with stepper motor; In step motor drive output, the extra-pulse encoder is through detecting the pulse error signal; And feed back to comparator; Comparator is constantly to the error signal of the controller output motor anglec of rotation, is decreased to till zero until the difference of command value and setting value, realizes peripheral close-loop feedback control.The utility model hybrid embroidery frame drive device has the following advantages: 1, a mixture of high-precision servo drive, and step into the driver's low prices; 2, to enhance the stepper driver does not have the anti-jamming capability; 3, enhance embroidery quality and cost-effective machine.
