The present invention is further described below in conjunction with drawings and Examples.A lot of details have been set forth in the following description so that fully understand the present invention.But the present invention can implement much to be different from alternate manner described here, and those skilled in the art can do similar popularization in the situation of intension of the present invention, so the present invention is not subjected to the restriction of following public specific embodiment.
Referring to Fig. 1, expression the present invention drives the flow process of progress control method one preferred embodiment of chain type conveyor line more.Described drive (two or more drive) catenary is respectively equipped with the tightening device with the chain tension more behind each actuating device, because each tightening device and chain link in the tensioning position, thereby the movement of tightening device detecting position has also just reflected the degree of tightness state of chain, if cross pine drive motor is accelerated, if tension then makes drive motor slow down, otherwise motor is moved by normal speed.For a certain group of actuating device and tightening device, can adopt following control method, concrete steps are:
(1) obtains target bit (location to be checked, particular location can not done requirement, as long as easy to detect just can) current location information of tightening device detecting position, in order to the tightness (step S101) of judging the target bit chain, wherein, the current location information of this detecting position is with the relation with respect to default tightening device detecting position traffic coverage, namely with testing result whether in interval, characterize greater than the interval upper limit or less than interval lower limit.
(2) judge the relative position relation (step S102) of target bit tightening device detecting position current location and default tightening device detecting position traffic coverage, also just can judge thus the degree of tightness state of chain.
(3) according to testing result, the relative position relation of target bit tightening device detecting position current location and default tightening device detecting position traffic coverage namely, determine that chain was pine, or tension, or normal, and drive motor accelerates, slows down or normal operation accordingly, specifically divides three kinds of situations:

If c target bit tightening device detecting position less than default tightening device detecting position traffic coverage lower limit, is confirmed target bit chain tension (step S107), and export the driving signal (step S108) that the target bit drive motor is run slowly.
Here, target bit drive motor normal operating speed remains preset reference speed, the Accelerating running Speed Setting is for surpassing preset reference speed 10%, run slowly Speed Setting for being lower than preset reference speed 10%, can not cause so whole chain the fluctuating widely of speed of dividing a word with a hyphen at the end of a line, can obtain preferably regulating effect thus.
In order to realize easily above-mentioned tension position testing process, in fixedly high speed detection position that each tightening device arranges, fixing low-speed detection position and can be with the trigger bit of chain movement, in order to be used for detecting the current position state of target tightening device, specifically trigger the current position state that detects target bit tightening device detecting position by detecting high speed detection position and the low-speed detection position position that whether is triggered.Mainly comprise following several types:
If high speed detection position and low-speed detection position all are not triggered, characterize target bit tightening device detecting position current location between default tightening device detecting position traffic coverage;
If the high speed detection position is triggered, characterize target bit tightening device detecting position current location greater than the default tightening device detecting position traffic coverage upper limit;
If the low-speed detection position is triggered, characterize target bit tightening device detecting position current location less than default tightening device detecting position traffic coverage lower limit.
Under special circumstances, also may exist high detection and low-speed detection position all to be triggered, only need to judge according to the detecting position that triggers first at this moment to get final product that therefore this situation can belong to above-mentioned the second type or the 3rd type, repeats no more.
More than set forth the present invention and driven the progress control method of chain type conveyor line more, according to the principle that this control method discloses, the present invention can correspondingly provide a kind of operation control system that drives chain type conveyor lines more, below specifically is described.
Referring to Fig. 2, expression the present invention drives the structure of the operation control system preferred embodiment of chain type conveyor line more.Be without loss of generality, two actuating devices 10,11 only are shown in the chain type conveyor line of this Fig. 2, wherein: behind the drive wheel of actuating device 10 9 and the drive wheel 12 of actuating device 11 is rear that a tightening device is set respectively, both are respectively with clump weight 4,8, consist of thus the counter weight type tensioner, in order to chain ABCD is strained.
As shown in Figure 2, this control system comprises two detecting units and a controller, wherein: detecting unit is by travel switch 1,2 and send out the parts such as number plate 3 and consist of, another detecting unit is by travel switch 5,6 and send out the parts such as number plate 7 and consist of, they can detect respectively the also current position state signal of export target position tightening device detecting position, can judge accordingly the tightness of target bit chain; Controller (Fig. 2 is not shown) is generally programmable logic controller (PLC) PLC, wherein stored Procedure and data, two detecting units of this controller access, current position state signal that thus can receiving target position tightening device detecting position, and advance control according to following preset strategy:
If target bit tightening device detecting position current location, confirms that target bit chain degree of tightness is suitable between default tightening device detecting position traffic coverage, and keep making the target bit drive motor with the driving signal of normal speed operation;
If target bit tightening device detecting position, confirms that the target bit chain is excessively loose greater than the default tightening device detecting position traffic coverage upper limit, and output makes the driving signal of target bit drive motor Accelerating running;
If target bit tightening device detecting position, is confirmed target bit chain tension less than default tightening device detecting position traffic coverage lower limit, and export the driving signal that the target bit drive motor is run slowly.
For detecting the current location of target bit tightening device detecting position, described detecting unit can be selected multiple detecting element, for example: detect in real time tension position by coded scale is set; Use infrared transmitter---the infrared remote receiver structure detection detects tension position; Etc..In the present embodiment, specifically adopt following manner to detect, so that simplified structure is saved cost.
If high speed detection element and low-speed detection element all are not triggered, characterize target bit tightening device detecting position current location between default tightening device detecting position traffic coverage;
If the high speed detection element is triggered, characterize target bit tightening device detecting position current location greater than the default tightening device detecting position traffic coverage upper limit;

Specific to pair driving chain type conveyor lines shown in Figure 2, each detecting unit adopts respectively travel switch 1,5 as the high speed detection element, adopts travel switch 2,6 as the low-speed detection element, and a number plate 3 is sent out in employing, 7 conducts can be with the trigger element of chain movement.Like this, whether trigger travel switch 1,2 by detecting a number plate 3, send out a number plate 3 and whether trigger travel switch 5,6, just can judge easily the current location of corresponding actuating device detecting position.
As shown in Figure 2, a high speed switch, a low speed switch respectively are installed before and after two tightening devices; Two drive motor are selected identical model as far as possible, can help to keep synchronously so that the motor output characteristic is consistent, conveniently control, and their speed change generally realizes by the frequency of regulating frequency converter.Particularly, frequency converter arranges respectively three sections speed (corresponding specific output frequency): one is datum velocity; Another is high speed (higher by 10% than datum velocity); Also have one to be low speed (than datum velocity low 10%).Normal circumstances, two all a certain datum velocity operations of drive motor; When a certain tightening device was run into high speed switch, the respective drive motor ran at high speed; When running into low speed switch, the respective drive motor is with low cruise.
Below further take two driving chain type conveyor lines as example, principle of work and the working process of control system of the present invention described.
Referring to Fig. 2, the service direction of chain is A-B-C-D, and there are the lifting part in this chain and corresponding elevated guideway, and its middle orbit rising part is with UP+(300mm or other specification) expression, the track sloping portion is with DOWN-(300mm or other specification) expression; Counterweight 4,8 is respectively the component part of corresponding tightening device; If conveyer chain fluffs, counterweight can spur balladeur train and be moved to the left; If it is tight that conveyer chain becomes, counterweight can spur balladeur train and move right; Send out number plate length 3,7 and be about respectively 300mm, they can move with balladeur train; Travel switch 1,5 was respectively applied to pine and detected, as was triggered, and respective drive motor 10 or 11 is accelerated; Travel switch 2,6 is used for tension and detects, as is triggered, and respective drive motor 10 or 11 is slowed down.
Like this, by travel switch 1 and 2 induction reflection CDA section conveyer chain degree of tightness states; By travel switch 5 and 6 induction reflection ABC section conveyer chain degree of tightness states.Because the conveyer chain total length is constant, one section pine in the CDA section of chain and the ABC section, other one section certainty is tight; Vice versa.
When a number plate 3,7 was not all run into travel switch, the motor of two actuating devices all moved with datum velocity;
When a number plate 7 is run into travel switch 5, illustrate that chain ABC section is excessively loose, drive motor 10 Accelerating runnings;
Run into travel switch 6 when sending out number plate 7, chain ABC section tension is described, drive motor 10 runs slowly;
Run into travel switch 1 when sending out number plate 3, illustrate that chain CDA section is excessively loose, drive motor 11 Accelerating runnings;
Run into travel switch 2 when sending out number plate 3, chain CDA section tension is described, drive motor 11 runs slowly.
Like this, be controlled at accordingly between two travel switches certain number plate mobile, whole conveyer chain just can normally move reposefully, and need not do too many consideration to the conformability of each drive motor output, drive motor output cumulative errors need not consider that also this is all very favourable for lectotype selection, field control aspect.
In embodiment illustrated in fig. 2, high speed detection element, the low-speed detection element of detecting unit are respectively travel switch 1,2,5,6, and trigger element is respectively sends out number plate 3,7, and they are a kind of contact induction mode.In fact, between high speed detection element and the trigger element, can be preferably contactless structure between low-speed detection element and the trigger element, can reduce like this collision, the prevention mechanical breakdown.During concrete type selecting, high speed detection element and low-speed detection element can be respectively approach switch or visible or infrared light formula photoelectric switch, and trigger element can be sends out number plate, and they can detect the current location of tightening device detecting position equally effectively.
Control system embodiment illustrated in fig. 2 specifically can be applicable to the Cantenary suspension conveying systems that drive more, at this moment can easily the number of sending out plate 3,7 be arranged at respectively on the balladeur train (Fig. 2 is not shown) that connects with conduction chain ABCD, their tensioner is preferably the counter weight type tensioner, its counterweight 2,8 connects respectively conduction chain, makes thus conduction chain keep balanced tension force.Certainly, optional spring loaded or cylinder or cylinder type counter weight device do not repeat them here yet.
In the present embodiment, large beating occur for preventing the chain speed of dividing a word with a hyphen at the end of a line, the rotating speed of motor should not fluctuate too large.For this reason, controller normally moves by preset reference speed control target bit drive motor, by surpassing preset reference speed 10% control target bit drive motor Accelerating running, run slowly by being lower than preset reference speed 10% control target bit drive motor, can reach so comparatively desirable control effect.
The embodiment of the invention is abbreviatied, and has solved cumulative errors in traditional control and the operation that causes when carrying is inconsistent plateau problem not, and this is undoubtedly a significant improvement with respect to prior art scheme by coder control motor speed.Even there are lifting in chain and track, the whole chain type conveyor lines that drive also can move reposefully, thereby applicable area is wider, and application prospect is good.
Although the present invention with preferred embodiment openly as above; but it is not to limit the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; can make possible change and modification, so protection scope of the present invention should be as the criterion with the scope that claim of the present invention was defined.
