Description of drawings
Fig. 1 is the constructional drawing of the short belt automatic deviation correcting of the present invention system;
Fig. 2 is a correction program flow chart of the present invention.
The specific embodiment
Referring to Fig. 1, be a kind of embodiment that lacks the belt automatic deviation correcting system of the present invention, comprise belt 10, head roll 1, changed course cylinder 11, belt deviation testing agency, automatic deviation correction mechanism and computer control system.
Automatic deviation correction mechanism is that the two ends of a traversing carriage bar 13 are hinged with 11 two ends of changed course cylinder respectively by two connecting rods 12, form parallel four-bar linkage, penetrate the rotating shaft 18 of a location in the middle of the traversing carriage bar 13, traversing carriage bar 13 can 18 rotate around the shaft, and rotating shaft 18 is installed on the permanent seat 17.Have one to be fixed on the cam 15 that the cam drive motor 16 cycloidal-pin wheel planetary reducer by high reduction ratio on the permanent seat 17 drives and to rotate, have a push rod 14 1 ends and cam 15 long radius places hinged, the other end and traversing carriage bar 13 1 ends are hinged.
Belt deviation testing agency is that feeler lever 3 front ends vertical with belt 10 limits are provided with runner 2, there is a displacement pickup 7 to be installed in above the adapter plate 6, the rotating shaft of displacement pickup 7 is passed below adapter plate 6 reaches, the rotating shaft lower end is connected with test rod 5 one ends, and test rod 5 other ends and feeler lever 3 rear ends are hinged.Also vertically penetrate a fork rotating shaft 8 on adapter plate 6, the fork rotating shaft 8 that is exposed on the adapter plate 6 is with torsion spring 9, and torsion spring 9 one ends are connected with fork rotating shaft 8 upper ends, and torsion spring 9 other ends are connected with adapter plate 6.Fork rotating shaft 8 below adapter plate 6 and a fork vertical connection of 4 one ends, the middle part of the other end of fork 4 and feeler lever 3 is hinged, and fork 4 is parallel with the test rod 5 of displacement pickup 7.Above-mentioned belt deviation testing agency is totally two covers, structure is identical, in the middle of runner 2 peripheries of its feeler lever 3 front ends is inner concave, the runner 2 of two cover belt deviation testing agencies relies on the elasticity of torsion spring 9 to withstand on respectively on belt 10 limits at close changed course cylinder 11 and head roll 1 place, and belt 10 limits are embedded in the runner 2 circumference inner concaves.Displacement pickup 7 and cam drive motor 16 all are connected with computer control system by signal wire (SW), and computer control system can adopt the PLC Programmable Logic Controller.
The principle of automatic deviation correction:
The realization of automatic deviation correction is to increase belt automatic deviation correcting mechanism at the changed course cylinder place of belt.This mechanism drives cam follower mechanism by the motor-driven that adapts to frequent starting through the cycloidal-pin wheel planetary reducer, and push rod drives the swing of changed course two ends, the cylinder left and right sides by four-bar linkage again, makes the left and right sides tensile force of belt change.Belt can be offset to the reversing sense of tensioning one end, thereby reaches the effect of correction.
The displacement of push rod and cam anglec of rotation θ relation are as follows:
The anglec of rotation θ of cam state as shown in fig. 1 is 90 degree, at this moment, changed course cylinder and head roll are parallel to each other, and spend when the cam of Fig. 1 state rotates counterclockwise 90, cam anglec of rotation θ is 0 degree, and push rod moves and makes the changing orientation drum shaft line rotate counterclockwise maximum angle; When the cam of Fig. 1 state clockwise rotates 90 degree, cam anglec of rotation θ is 180 degree, and push rod moves and makes the changing orientation drum shaft line clockwise rotate maximum angle.
The speed of correction speed is subjected to two factor affecting.The one, belt speed; The 2nd, the displacement of cam follower, the i.e. tensile force of belt.And in the real work, we are concerned about most is whether belt deflects away from cylinder and cause and reveal or fault such as belt tearing.So, determine the action of automatic deviation correction mechanism only according to the size of belt side-play amount.
The process of automatic deviation correction is similar to the control of vehicle steering.Suppose a traveling automobile on two track highways, want all the time to remain on the demarcation line.If certain reason makes that we need the reverse bearing circle of adjusting to make its trend of oriented time to automobile so towards a direction skew.When automobile can be got back to the demarcation line, we need return the normal position with bearing circle, and vice versa.
Belt can be to a direction skew under the effect of certain external force.When scope that surpass to set, the automatic deviation correction mechanism action makes the trend of oriented time of belt.When in the scope of getting back to setting, mechanism turns back to original position with automatic deviation correction.When belt when other direction is offset, automatic deviation correction mechanism carries out same action, just direction is opposite.Finally make belt reach a kind of dynamic balance.
The method of automatic deviation correction:
The action of automatic deviation correction is finished by the cam drive motor.Because the reduction ratio of cycloidal-pin wheel planetary reducer is fixed, thus the current"on"time of cam drive motor just corresponding the displacement of cam follower, the hand of rotation correspondence of cam drive motor push rod and is advanced or retreat.
According to the short travel belt in changed course cylinder offset and the out-of-position servo-actuated of head roll place, with the belt side-play amount at changed course cylinder place adjustment foundation as the cam drive motor action.For reducing the operating frequency of cam drive motor, under the prerequisite that satisfies less than the belt maximum offset, belt is divided into the N section to the side-play amount of a direction.The course of action of cam drive motor also is divided into the N level and adjusts in view of the above.Each adjustment amount increases along with the increase of belt side-play amount.Total adjustment time is less than and equals cam mechanism and revolve the time of turning 90 degrees.
When cam drive motor positive action arrived to a certain degree, belt will oriented time out-of-position trend.In the time of in belt is got back to setting range, the cam drive motor is oppositely adjusted.Here for guaranteeing that automatic deviation correction mechanism not in the vibration of forward adjustment value place, establishes forward adjustment value and reverse adjustment value respectively in the adjustment process of each grade.Oppositely the belt side-play amount at adjustment value place is less than the belt side-play amount at forward adjustment value place.
The principle of adjusting is after belt is got back to line of centers left and right sides certain limit, and the cam anglec of rotation of automatic deviation correction mechanism should be at 90 degree places.It is the parallel axes of changing orientation drum shaft line and head roll.The time of forward adjustment should be identical with the time of reverse adjustment for this reason, i.e. the number of times of forward adjustment should be identical with the number of times of reverse adjustment.But in real work, be subjected to the restriction of field working conditions, such as the bonding quality of belt comprises the wearing and tearing of the quality edge of belt itself, the saltus step that impact of belt load or the like all might cause belt deviation to detect, and then cause the misoperation of automatic deviation correction mechanism.Destroy forward, oppositely adjust temporal balance, cause the accumulated error of deviation correction mechanism cam position of rotation.When this error surpassed to a certain degree, original position can't return with the belt adjustment in automatic deviation correction mechanism, so that skew excess (exceed the cylinder edge and cause disorderly closedown) occurs.For addressing this problem, on Control Software, introduce strict the equating of number of times that soft rest-set flip-flop is adjusted each grade Direct/Reverse.Be forward adjustment value and oppositely adjustment value set each other and the trigger condition that resets.At each grade forward adjustment value place,, must there be the zone bit of the reverse adjustment value of this grade to exist if want to allow the cam drive motor action.And after having adjusted, the reverse adjustment value of this grade is removed.In like manner, at the reverse adjustment value place of each level,, must there be the zone bit of this grade forward adjustment value to exist if want to allow the cam drive motor action.And after having adjusted, the forward adjustment value of this grade is removed.
Referring to Fig. 2, the concrete steps of each grade automatic deviation correction are as follows:
Belt deviation testing agency converts electric signal to and sends in the computer control system with will the alter course belt deviation amount at cylinder place of the mode of polling cycle, (1) the belt side-play amount surpasses previous stage forward adjustment value, when arriving the reverse adjustment value of this grade, reverse adjustment zone bit is set in computer register.(2) computer control system judges whether forward adjustment value zone bit is deposited.(3) if forward adjustment value zone bit does not exist, then do not do any action, wait for that belt continues skew.(4) if forward adjustment value zone bit exists, computer control system is sent instruction, and the cam drive motor reverses n second.(5) after reverse the adjustment, the forward adjustment value zone bit of this level in the computer control system dump register.(6) when computer control system is judged the belt side-play amount and arrived the forward adjustment value of this grade, forward is set in computer register adjusts zone bit.(7) computer control system judges whether reverse adjustment value zone bit exists.(8) if oppositely the adjustment value zone bit does not exist, and the belt side-play amount is not then done any action above allowed band, wait belt continuation skew.(9) if oppositely the adjustment value zone bit exists, computer control system is sent instruction, and the cam drive motor just changes.(10) after forward was adjusted, computer control system was removed the reverse adjustment value zone bit of this grade.(11) if belt begins to return under the effect of forward adjustment, and arrive the reverse adjustment value of this grade, computer control system is sent instruction, the counter-rotating of cam drive motor.(12) after reverse the adjustment, the forward adjustment value zone bit of this level of computer control system dump register.(13) if belt does not return under the effect of forward adjustment, and the belt side-play amount enters next stage and adjusts program above allowed band.
