Abstract
The utility model provides a rotation control device for a cold roller disk crimper, which is mainly composed of a PLC controller, a position detecting element, a frequency converter or an inverter, and a main drive motor, wherein the position detecting element transmits position signals to the PLC controller to realize position feedback; the PLC transmits given speed to the frequency converter or the inverter according to the position feedback; the frequency converter or the inverter realizes the closed-loop control on the speed of the main drive motor according to speed feedback, wherein the position detecting element is an encoder which continuously transmits the position signals to the PLC controller to realize the position feedback. The utility model solves the problem existing in the original system that large errors of position detection affect control accuracy, raises positioning accuracy from the original about 15 mm to about 1.5 mm, and simultaneously has the characteristics of simple structure and easy implement.
Description
Technical field
The utility model relates to a kind of electrical control gear, especially a kind of electrical control gear that is used to realize wheel disc crimping machine positioning of rotating.
Prior art
The crimping machine that adopts at cold rolling associating unit is the wheel disc crimping machine, and its equipment constitutes and comprises that two reels of No.1, No.2,180 degree are provided with, wheel disc body, a detent, a binding clasp, main drive motor and lubrication assistant equipment; Control is used incremental encoder to detect the main drive motor actual speed with pick-up unit and is realized speed closed loop, use the physical location near switch detection wheel disc spins to be rotated the location.Two reels are in rolling position (No.2) respectively and wear band position (No.1) in the belt steel rolling process, and the reel (No.2) of rolling position be the work reel, by its band steel that curls, are holding state and wear a reel (No.1) of being with.When this rolls up rolling end, after flying shear was sheared, new tape head was entangled to by rolling-assisting device and wears band reel (No.1) and carry out continuous rolling.When the coil of strip on the reel of rolling position unloads volume and finishes, the starter cup disc spins rotates to the former band reel (No.1) of wearing rolling position and switches to the work reel, and the reel (No.2) of former rolling position switches to naturally and wears the band reel standby, and after rotary course finished, wheel disc locked.It more than is the complete course of work of wheel disc crimping machine.In original device, control system is made up of PLC controller, position detecting element (3 near switch), frequency converter, main drive motor.It specifically is controlled to be: the position of rotation of wheel disc detects and is provided with 3 near switch, and the position of rotation that is respectively wheel disc is near switch 1 (110 degree detect), near switch 2 (170 degree detect), near switch 3 (180 degree detect).When the position of rotation arrival 110 of wheel disc was spent, near switch 1 sender, the PLC controller sent instruction, and main drive motor reduces speed now; When position of rotation arrival 170 was spent, near switch 2 senders, the PLC controller sent instruction, and main drive motor begins braking; Position of rotation arrives 180 when spending, and near switch 3 senders, this switch is the signal that is rotated in place of wheel disc, this moment the main drive motor end of braking, wheel disc stops operating, binding clasp clamps wheel disc, the wheel disc locking.From as can be seen above, the switching point of main drive motor speed control is that 3 position probing are near switch.But we find in actual use, because detecting, the physical location of wheel disc spins adopts near switch, can not continuous detecting, and accuracy of detection is lower, can only reach ± 15mm, can not accurately reflect the physical location of taking turns disc spins, often occur in advance or the phenomenon of hysteresis sender near switch, cause the switching of main drive motor speed control inaccurate, actual not in place can't the clamping of wheel disc spins can not be continued rolling or wheel disc rotates through a bump detent and causes physical damage, can't normally use.
Summary of the invention
The purpose of this utility model is to provide a kind of cold rolling wheel disc crimping machine rotating control assembly, so that realize the hi-Fix of wheel disc crimping machine rotation.
The purpose of this utility model is to realize like this, a kind of cold rolling wheel disc crimping machine rotating control assembly, mainly form by PLC controller, position detecting element, frequency converter or inverter, main drive motor, send position signalling by position detecting element and realize position feedback to the PLC controller, given to frequency converter or inverter by PLC according to the position feedback transmission speed, realize the speed closed loop control of main drive motor in conjunction with velocity feedback by frequency converter or inverter, wherein position detecting element is a scrambler, sends position signalling continuously and realizes position feedback to the PLC controller.
The utility model changes the use scrambler into as position detecting element owing to having cancelled by the wheel disc position of rotation detection that realizes near switch in system, the continuous position of having realized the wheel disc spins detects, the position detection error that has solved the original system existence influences the problem of control accuracy greatly, and bearing accuracy is brought up to ± 1.5mm by former ± 15mm.Avoided to clamp and to have continued rolling and wheel disc rotates through a bump detent and causes physical damage, had simple and reliable for structurely simultaneously, implemented the characteristics that are easy to because of the actual rotation of wheel disc is not in place.
Description of drawings
Fig. 1 is a control flow chart of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of cold rolling wheel disc crimping machine rotating control assembly of the present utility model, mainly form by PLC controller, position detecting element, frequency converter or inverter, main drive motor, send position signalling by position detecting element and realize position feedback to the PLC controller, given to frequency converter or inverter by PLC according to the position feedback transmission speed, realize the speed closed loop control of main drive motor in conjunction with velocity feedback by frequency converter or inverter, wherein position detecting element is a scrambler, sends position signalling continuously and realizes position feedback to the PLC controller.When the position of rotation arrival 110 of wheel disc was spent, the PLC controller sent instruction, and main drive motor reduces speed now; When position of rotation arrival 170 was spent, the PLC controller sent instruction, and main drive motor begins braking; Position of rotation arrives 180 when spending, this moment the main drive motor end of braking, wheel disc stops operating, binding clasp clamps wheel disc, the wheel disc locking.
The scrambler of the position detecting element in the utility model can adopt dual mode: a kind of is absolute value encoder, directly be connected as PROFIBUS DP substation on the PROFIBUS DP network of PLC, send the position signalling of wheel disc crimping machine rotation to PLC continuously.Another kind is an incremental encoder, and this scrambler sends the position signalling of wheel disc crimping machine rotation continuously to PLC by counter module.
