The specific embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1 and Figure 2, under normal production run state, tow carries out shredding and stretches between input roller V1 and worm felt roll V2, and its shredding width keeps constant substantially, and the tow width of setting normal shredding is W1.But, after the tow with spelling joint A2 enters input roller V1, due to by the tow spelling joint A2 of charing normally shredding stretch, its shredding width will be reduced to 30% original left and right, the tow width of setting with the shredding of tow spelling joint A2 is W2.The utility model utilizes the acute variation of tow width to identify the existence of tow spelling joint A2 just.
The tow spelling joint of filter-stick forming device provided by the utility model detects elimination method and comprises the step that detects tow spelling joint A2:
The width of the tow that shredding between input roller V1 in filter-stick forming device and worm felt roll V2 is stretched detects, and, is determined with tow spelling joint A2 and passes through less than default width W the time when the width of detected tow.W2＜W＜W1, wherein, W1 is the tow width of normal shredding, and W2 is the tow width with the shredding of tow spelling joint A2, and generally, W2 approximates greatly 30%W1.
In the present embodiment, the step that detects tow spelling joint A2 is specific as follows:
As shown in Figure 2, at first two spelling joint test points are set, and these two spelling joint test points are arranged on tow two ends in the middle of input roller V1 and worm felt roll V2, as the point of the M in Fig. 2 and N point, and the horizontal range between M point and N point is arranged to W, and W2＜W＜W1, wherein, W1 is the tow width of normal shredding, and W2 is the tow width with the shredding of tow spelling joint A2.
As can be seen from Figure 2, if the tow of normal shredding is by two spelling joint test points (the M point shown in Fig. 2 and N point), be positioned at two spelling joint test points that M point and N order and the signal that tow passes through to be detected, the width of the tow that expression is passed through is greater than W, and can determine does not have tow spelling joint A2 to pass through; If passed through two spelling joint test points by the tow spelling joint A2 of charing, be positioned at two spelling joint test points that M point and N order and all the signal that tow passes through can't be detected, the width of the tow that expression is passed through can determine tow spelling joint A2 and pass through less than W.This tow spelling joint detection mode can realize in the situation that equipment detects the tow spelling joint automatically with the arbitrary speed operation, and is very accurate and convenient and swift.
Because the spelling joint test point is changeless apart from the distance L of removing filter-stick mechanism, the length l of every filter stick is also constant, so when tow spelling joint A2 moves to the removing filter-stick mechanism position, filter-stick forming device will be produced n(n=L/l, be fixed constant) the root filter stick, corresponding filter stick number testing agency will produce 4n pulse signal this moment, and the filter stick that this 4n pulse signal is made afterwards is only the defective filter stick of making by with the tow of spelling joint A2.So the utility model is not at once the filter stick of producing to be rejected, but just begins filter stick is rejected when tow spelling joint A2 moves to the removing filter-stick mechanism position when being determined with tow spelling joint A2 and passing through.That is to say, move to the time point of removing filter-stick mechanism position as tow spelling joint A2, be initial rejecting time point.
And, number by the defective filter stick made from the tow of spelling joint A2 is also limited, therefore removing filter-stick mechanism is also limited to the duration of removing filter-stick, so carrying out to reject to move, removing filter-stick mechanism has a time range, this time range can be redefined for (4n-a, 4n+a), 4n-a wherein is initial rejecting time point, and 4n+a is for stopping rejecting time point.
In sum, when being determined with tow spelling joint A2 and passing through, the tow spelling joint of filter-stick forming device provided by the utility model detects elimination method and also comprises and trigger the step that pulse signal that filter stick number testing agency is generated is counted.This triggering step can realize accurate triggering, has effectively controlled the rejecting number of filter stick, and then has avoided the waste of extra raw and auxiliary material.
In above-described embodiment, the tow spelling joint of filter-stick forming device provided by the utility model detects elimination method and comprises that also the step of rejecting tow spelling joint A2 is:
The pulse signal that filter stick number testing agency generates is counted;
When the pulse signal number accumulative total that generates when filter stick number testing agency reaches default initial rejecting time point, drive removing filter-stick mechanism and begin to carry out and reject action;
The pulse signal number accumulative total that generates when filter stick number testing agency reaches default termination when rejecting time point, drives removing filter-stick mechanism and stops carrying out and reject action.
In the present embodiment, removing filter-stick mechanism is (4n-a, 4n+a) to the duration scope of removing filter-stick.Wherein, n=L/l, L are the distance between spelling joint test point and removing filter-stick mechanism, and l is the length of every filter stick, the fixed constant of a for setting.In the present embodiment, a is 20, and amount to 10 filter sticks this moment will be disallowable.
In the various embodiments described above, when removing filter-stick mechanism stopped filter stick being rejected, the counting of the pulse signal that filter stick number testing agency is generated carried out zero clearing, waits for flip-flop number signal next time.
As shown in Figure 3, the utility model also provides a kind of tow spelling joint of filter-stick forming device to detect device for eliminating, it comprises spelling joint testing agency 1, is arranged in forming machine between input roller V1 and worm felt roll V2, is used for having determined whether that tow spelling joint A2 is by this test point.
Spelling joint testing agency 1 comprises tow width detection unit 11, width for detection of tow between input roller V1 in forming machine and worm felt roll V2, when the width of detected tow less than default width W the time, spelling joint testing agency 1 is determined with tow spelling joint A2 and passes through.Wherein, W2＜W＜W1, W1 are the tow width of normal shredding, and W2 is the tow width with the shredding of tow spelling joint.
In the present embodiment, what tow width detection unit 11 adopted is two pairs of correlation optical fiber, and two pairs of correlation optical fiber are arranged on respectively near tow two sides in the middle of input roller V1 and worm felt roll V2, and has a spacing between tow two sides.As shown in Figure 2, this set-up mode is specially:
First pair of correlation optical fiber comprises the first transmitting terminal M and the first receiving terminal N, and second pair of correlation optical fiber comprises the second transmitting terminal M ' and the second receiving terminal N '.The first transmitting terminal M and the second transmitting terminal M ' all are located at a side of the tow in the middle of input roller V1 and worm felt roll V2, and interval both, and namely horizontal mounting distance is arranged to W, and W2＜W＜W1.Similarly, the first receiving terminal N and the second receiving terminal N ' all are located at the another side of the tow in the middle of input roller V1 and worm felt roll V2, and interval both, and namely horizontal mounting distance is arranged to W, and W2＜W＜W1.Certainly, the receiving port direction of the emission port direction of the first transmitting terminal M and the first receiving terminal N is over against setting, and the receiving port direction of the emission port direction of the second transmitting terminal M ' and the second receiving terminal N ' is over against setting.
Installing space between the first transmitting terminal M and the first receiving terminal N, the second transmitting terminal M ' and the second receiving terminal N ' is decided by the tow opening width, its width slightly is narrower than the tow width of normal shredding, the requirement in its when debugging is: at non-tow with tow spelling joint section after input roller V1 and worm felt roll V2 shredding, during by this two pairs of correlation optical fiber stable operations, these two pairs of correlation optical fiber can detect tow and exist.And when the tow with spelling joint A2 section passed through this two pairs of correlation optical fiber, two pairs of correlation optical fiber all can not detect the existence of tow.
If the tow of normal shredding is when passing through, first pair of correlation optical fiber and second pair of correlation optical fiber should detect the signal that tow passes through, and at this moment, namely the width of tow is greater than W; If when being passed through by the tow spelling joint A2 of charing, first pair of correlation optical fiber and second pair of correlation optical fiber all can't detect the signal that tow passes through, and at this moment, namely the width of tow is less than W.That is to say, when and if only if first pair of correlation optical fiber and second pair of correlation optical fiber is not all covered, just can be determined with tow spelling joint A2 and from then on pass through.
Obviously, also can adopt other tow width detection unit to substitute above-mentioned disclosed correlation optical fiber, whether have tow spelling joint A2 from then on to pass through to detect.
As shown in Figure 4, the tow spelling joint of filter-stick forming device provided by the utility model detects device for eliminating and also comprises: removing filter-stick mechanism 2, filter stick number testing agency 3 and controller 4, the input port of controller 4 is electrically connected to tow width detection unit 11 and filter stick number testing agency 3, and the output of controller 4 is electrically connected to the rejecting valve K in removing filter-stick mechanism 2.Wherein:
