Abstract
The invention discloses a movable trolley control system which comprises a movable trolley, wherein a drive motor is arranged on the movable trolley, the movable trolley comprises a PLC (Programmable Logic Controller), an analog quantity output module of the PLC is connected with the drive motor through a frequency converter, and the PLC is also connected with an advancing reduction place sensor, an advancing stop place sensor, a retreating reduction place sensor and a retreating stop place sensor. By adopting the movable trolley control system, vibration generated when the speed of the movable trolley is converted is avoided so that the movable trolley moves very stably, the speed of the movable trolley and the working efficiency are increased.
Description
Technical field
The present invention relates to a kind of production line travelling car, particularly a kind of speed control system of travelling car.
Background technology
It mainly is to carry through travelling car that product on production line is carried; Present travelling car mainly adopts scrambler to read the dolly displacement data, length and the dolly that on touch-screen, sets the dolly displacement length of position of slowing down, when dolly in high-speed mobile; When scrambler reads the deceleration bit data; Dolly changes low speed into and moves, and when scrambler read the position of rest data, dolly stopped.Because do not adopt analog quantity control, dolly can only have two kinds of speed when mobile, when transferring low speed at a high speed, dolly has tangible vibrations, and at a high speed De Taigao can't be set, and too high vibrations are just obvious more.
Summary of the invention
To the deficiency of above-mentioned prior art, the technical matters that the present invention will solve is to realize a kind of travelling car control system of the steady conversion rate of dolly.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of travelling car control system; Comprise a travelling car; Said travelling car is provided with drive motor; It also comprises a PLC controller, and the analog output module of said PLC controller is connected with said drive motor through a frequency converter, and said PLC controller is also retreated deceleration level sensor and and retreated the position of rest sensor and be connected with deceleration level sensor, the position of rest sensor, that advances that advances.
Preferably, also be provided with forwarding button, back and stop button on the said travelling car, said forwarding button, back, stop button all are connected with said PLC controller.
Preferably, said PLC controller also is connected with a touch-screen.
Technique scheme has following beneficial effect: the travelling car control system adopts the analog output module of PLC controller that the frequency converter of motor is controlled; At first set travelling car shift length and travelling car deceleration bit length in use, and set the high speed and the low speed data of travelling car, when travelling car the time with high-speed mobile; The displacement data that the PLC controller reads according to scrambler calculates corresponding speed; Displacement is big more, and speed is low more, when travelling car is sensed travelling car deceleration position; Speed has also become low speed; Deceleration position from the start bit of travelling car to travelling car has just formed a big speed ramp like this, in the frequency range that motor allows, higher velocity of displacement can be set simultaneously.The vibrations that produce when adopting this travelling car control system to avoid the travelling car rate conversion, very steady when travelling car is moved, improved the speed of travelling car, also just improved its work efficiency.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of instructions, below with preferred embodiment of the present invention and conjunction with figs. specify as after.Embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail.
As shown in Figure 1; This travelling car control system comprises a travelling car and a PLC controller 1; Travelling car is provided with drive motor 3; The analog output module of PLC controller 1 is connected with drive motor 3 through a frequency converter 2, and PLC controller 1 is also retreated deceleration level sensor 6 and and retreated the position of rest sensor and be connected 7 with deceleration level sensor 4, the position of rest sensor 5, that advances that advances.Through the signal of the sensor feedback, 3 actions of PLC controller 1 may command drive motor make travelling car realize corresponding operating.On travelling car, also be provided with forwarding button 8, back 9 and stop button 10 and touch-screen 11 and be connected, make things convenient for the control of travelling car like this.
The travelling car that adopts this control system at first sets travelling car shift length and travelling car deceleration bit length through touch-screen 11, and sets the high speed and the low speed data of travelling car in use; When travelling car with high-speed mobile the time, the displacement data that PLC controller 1 reads according to scrambler calculates corresponding speed, and displacement is big more; Speed is low more; When travelling car was sensed travelling car and slowed down the position, speed had also become low speed, and the deceleration position from the start bit of travelling car to travelling car has just formed a big speed ramp like this; In the frequency range that motor allows, higher velocity of displacement can be set simultaneously.
The vibrations that produce when adopting this travelling car control system to avoid the travelling car rate conversion, very steady when travelling car is moved, improved the speed of travelling car, also just improved its work efficiency.
More than a kind of travelling car control system that the embodiment of the invention provided has been carried out detailed introduction; For one of ordinary skill in the art; According to the thought of the embodiment of the invention, the part that on embodiment and range of application, all can change, in sum; This description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
