The midway location of described movable pulley 6 path of motion and two end positions, be respectively arranged with a travel switch, described travel switch is connected with control system.
Tension force in band material is analyzed:
As shown in Figure 3, when being in the movable pulley in the middle of fixed pulley and not moving or at the uniform velocity move.Band material tension force T equals 1/2nd [T=(G+F)/2] of movable pulley gravity G and force application mechanism directed force F sum.Here the directed force F of force application mechanism also can be contrary with pulley gravity G direction, then [T=(G-F)/2].
As the gravity G of movable pulley, be a half of the tension force T of needs just, just do not need force application mechanism---the method for " counterweight " can be adopted, the gravity G of adjustment movable pulley.
More than analyze, have ignored the friction force of pulley bearings and pulley and band material, and pulley produces the force of inertia after acceleration/accel or moment of inertia etc.If need strict control cincture material tension force, in above-mentioned formula, the force of inertia or moment of inertia etc. of friction force and pulley should be counted.
Actual when using, first with reference to technique for coiling, according to the tensile requirements with material after coiling, determine movable pulley and force application mechanism with joint efforts.Then, when whole system band material outdevice and coiling are tied before the equipment life's work of shape, band material is tightened to the midway location of the movable pulley in function assembly pulley at total kilometrage in advance.At this moment the band material internal tension between two fixed pulleys is exactly the half that movable pulley and force application mechanism are made a concerted effort.
A kind of function assembly pulley for tying shape curling machine of the present invention in use, each pulley in function assembly pulley walked around successively by band material according to throughput direction, in winding process, due to the continuous change of band material length in function assembly pulley, movable pulley is constantly moved, depart from midway location, thus practical function assembly pulley is to " storage " or " release " of band material.Have in the track that movable pulley moves back and forth " midway location " of a stroke, when movable pulley departs from above-mentioned " midway location ", the rotating speed of movable pulley both sides fixed pulley is different, the number of signals of the rotary encoder connected by coupler is also different, the control system be then connected with rotary encoder just can differentiate the sense of motion of now movable pulley according to the difference of the electric signal received, learn that function assembly pulley has been " storage " or " release " and has been with material.Now, control system is by the rotating speed of coiling axle in adjustment curling machine, and make movable pulley always in the process returning to " midway location ", then the tension force on the bundle shape band material after coiling, all meets tensile requirements.
The control of function assembly pulley to band material internal tension can be adopted in two ways: 1, utilize the method to movable pulley counterweight, movable pulley is connected and installed with the counter weight device of weights, control the tension force of strips of deformable material; 2, utilize the force application mechanism that movable pulley connects, control the tension force in strips of deformable material.
During the set up procedure of curling machine before coiling, strips of deformable material is strained gradually---movable pulley is R point when the midway location of total kilometrage.In winding process, according to the electric signal of rotary encoder, differentiate by control system the band material that has been this moment " storage " or " release " in function assembly pulley.The control system of curling machine keeps movable pulley always near " midway location ".When in control system discrimination function assembly pulley being " storage " band material, by improving the rotating speed of coiling coiling axle, " release " is gone out more to be with material; When in control system discrimination function assembly pulley being " release " band material, by the rotating speed of coiling coiling axle that slows down, " storage " is more with material, makes movable pulley produce the motion being returned to " midway location ", thus maintain movable pulley always near " midway location ".
In a kind of function assembly pulley for tying shape curling machine of the present invention, the both sides of movable pulley can need to arrange multiple fixed pulley according to equipment, and fixed pulley can singlely be arranged, and also can arrange to arrange can utilize space in order to save more.Rotary encoder is arranged on arbitrary two fixed pulleys in movable pulley both sides, and the diameter of fixed pulley that the rotary encoder of same model is installed should be identical.When fixed pulley diameter when about movable pulley is identical, if during the rotating speed of the rotating speed being positioned at the fixed pulley of movable pulley feed end faster than the fixed pulley of movable pulley discharge end, control system will send instruction, the coiling axle of curling machine is by revving up, make the faster rotational speed of the fixed pulley of movable pulley discharge end, otherwise then situation is contrary.
In function assembly pulley of the present invention, the path of motion of movable pulley is any one in straight line or circular arc, and path of motion comprises two end positions and a midway location.The midway location of movable pulley path of motion and two end positions, be respectively arranged with a travel switch, travel switch is connected with control system.In order to record the sense of motion of movable pulley, learn that function assembly pulley has been " storage " or " release " and has been with material.
