explanation
Usually to the article used by consumer being processed the feature of thinking that consumer provides or guaranteeing its quality.The process that can be applicable to a type of article is with text, image, pattern, alphanumeric code, linear or matrix bar code, or other mark carrys out tagged items.These marks can be used for different objects, comprise the information providing related articles, identify objects and article and similar articles being distinguished, or strengthen the outward appearance of article.The article process of another kind of type carrys out coated article with surface coating, and described coating can provide required sense of touch, vision, or other organoleptic attribute, such as taste or fragrance.Process also can comprise the attribute detecting described article, such as color, surface smoothness, or the presence or absence of mark or fault of construction.No matter the expection object of process is how, for process is as one man applied to each article ability normally, to produce consistent final products and/or the authentic data of acquisition on goods attribute.
Under the typical batch throughput rate being suitable for goods for consumption, be sometimes difficult to as one man process article.This when particularly at high speeds by transmit article enterprising row relax time especially true.In this case, uniformity for the treatment of applies the control depended on relative motion between article and processing unit.Following the tracks of, the degree of accuracy in this relative motion is not enough in determining that the position of article on forwarder transport path produces uncertain under preset time.Above-mentioned uncertainty is exaggerated in the following cases: a) when item sizes reduces, reduce for carrying out the target area processed; And b) when transfer rate increases, shorten for carrying out the object time window processed.As probabilistic result, may be properly oriented based on article so that the expectation carrying out processing performs process, but in fact really not so.Such as, article can shift to an earlier date along the transport path of forwarder or lag behind its desired location.On the other hand, the article transmitted subsequently may be properly positioned when processing execution, and result will be different for these article compared with first article.That is, the inconsistent process of article and the inconsistent results that caused by it can be caused by the relative motion inaccurately followed the tracks of between transmitted article and processing unit.The inconsistency of process may damage required attribute and the quality of goods for consumption.
Various device can be used for promoting institute transmit article and along forwarder transport path layout one or more processing units between the tracking of relative motion.Motion sensor can be used for detecting motion, such as, drive the rotary motion of the motor drive shaft of forwarder driver, described motion so that make forwarder bearing carrier together with it carry the load of article to move along forwarder transport path.According to well known to a person skilled in the art electrically and mechanical relation, the output of described motion sensor can be relevant to the linear movement of bearing carrier, comprises speed and distance of increment that the point on bearing carrier advances.For have integrated article carrying apparatus (such as attached retainer or machined cavity) fixing layout bearing carrier for, the speed that the linear movement of bearing carrier then can be advanced to institute's transported substance product on bearing carrier is relevant with distance of increment.
But, need position reference point to determine the article that transmit under preset time along the accurate location of forwarder transport path.For providing in a kind of scheme of reference point, iron content insert can be integrated in bearing carrier.Along forwarder transport path settle magnetic sensor for detecting this insert.Fix for the bearing carrier of layout for having fixing layout such as cavity, the distance between insert and given cavity along bearing carrier length is known.Therefore, detect insert time this time inscribe, insert provides position data relative to the position relationship of cavity to the article kept in cavity.This transient state (snapshot) of article position is provided for following the tracks of it subsequently along the starting point that forwarder transport path moves.Use the linear motion data from motion sensor, when measurable in theory article will arrive the position processing and will be performed, and processing unit can be activated by inference under reasonable time.
The detection that the problem of this scheme is iron content insert in bearing carrier too out of true to such an extent as to enough position datas can not be provided to the article be held in cavity.The wide in range dome-shaped gabarit in insert magnetic field makes insert can detect in only more wide in range compared with insert surface region.This situation aggravation when there is the moving up and down of bearing carrier, as common in transfer system.Moving upward of insert makes the wider base portion of magnetic field gabarit closer to magnetic sensor, increases the region can detecting insert within it.Because the detection in this broad range can only provide approximate position for insert, this scheme can only provide the approximate relative location of article on bearing carrier as can be seen here.Especially, when less article are with High Speed Transfer, the approximate instruction of article position does not allow to carry out accurate, consistent process to article.
For obtain the another kind of scheme of the initial reference point for following the tracks of the position of article on forwarder bearing carrier be use sensor carry out test item itself.But, when have bearing carrier that article transfer machine fixes layout do not load completely and detected by sensor do not have article to be in empty retainer or cavity time, this scheme will lose efficacy.In addition, even if when article really being detected, this scheme provides enough position datas can not to accurately processing subsequently of article.
Such as, article sensor can be configured to detect the article in a row or in one-tenth array article that bearing carrier is transferred, and can be configured to provide the position data for article.Then the position of remaining articles is determined relative to the position of these article.But, if this detected article dislocation, such as its retainer or cavity tilted or crooked, then can not in a row or become each article in array correctly determine position data.Any subsequent treatment based on article position then will be applied improperly.In another example, the sensing range of article sensor may be too wide to such an extent as to provide enough position datas can not to the follow-up accurate process of article.
