Abstract

The utility model discloses an online detection device for loose or missing cigarette filters, which comprises a cigarette detection passage. A selector drum is mounted in the cigarette detection passage, and a filter missing sensor and a filter looseness sensor are mounted on the selector drum. The photoelectric filter missing sensor and the capacitive filter looseness sensor are used for online detection of cigarettes, signals from the filter looseness sensor and the filter missing sensor are acquired and determined by a micro-processing system according to synchronous signals, and defective cigarettes are rejected on a rejecter drum after corresponding delay is made. The online detection device for loose or missing cigarette filters is simple in structure while detection accuracy is improved.

Description

The on-line measuring device of a kind of cigarette Zhi Songtou and scarce filter tip

Technical field

The cigarette that the utility model relates in a kind of cigarette production line props up online quality detection device, specifically is a kind of on-line measuring device that is used for cigarette Zhi Songtou and scarce filter tip.

Background technology

At present, the cigarette online detection of cigarette quality of propping up spicing machine comprises that mainly scarce filter tip, pine head and dilution factor detect three parts.Lack filter-tip cigarette and detect drawing close on the drum through photoelectric sensor, utilizing blows props up two cigarettes that lack filter tip to draw close the back to be rejected eliminating on the drum.It is cigarette Zhi Jinhang pine head to be detected on the selection drum through loose header detector that a pine cigarette detects, and dilution factor detects the employing detection of negative pressure.The parameter that data that the microprocessor that utilizes detection system props up every cigarette and machine preset compares, and the cigarette that exceeds setup parameter props up and belongs to the cigarette that exceeds standard and prop up, and will reject disallowablely on the drum to fall.Fig. 1 is existing checkout gear; It needs two measuring stations; Measure pressure value P 1 by first B/P EGR Back Pressure Transducer EGR 1 during every cigarette process measuring station A, measure pressure value P 2 through measuring station B by second B/P EGR Back Pressure Transducer EGR 2 again afterwards, negative pressure is to provide by being installed in the outside wind sucting chamber 3 of sense channel.The ratio that calculates these two force value promptly obtains the dilution factor that cigarette props up.If this ratio is in set parameter area, this cigarette just through detecting drum, arrives rearmost transmission drum through rejecting drum; If exceed parameter scope is set, cigarette props up will be disallowable on the rejecting drum.

In this detection system, there are three problems:

(1) lack filter tip and detect that to detect the drum of being separated by more with bear and dilution factor because that the omission that lacks the filter tip sensor and yew paper bag are wrapped up in is defective, have lack cigarette filter and be transferred to after grade drum.

(2) a photo-electric pine detector need often carry out cleaning surfaces, and there is decay in various degree in the long-time running photoelectric tube, causes detecting inaccurate.

(3) dilution factor detects because the factor of aspects such as cigarette quality, lock-out pulse, calibration, suction cover, decrement, sealing ring and negative pressure; In practical application, occur sometimes bad cigarette prop up can not pick, good cigarette props up situation such as picked out, exist lacking the omission of filter-tip cigarette.

The utility model content

It is accurate that the utility model technical problem to be solved provides a kind of detection, the cigarette Zhi Songtou that loss is low and the on-line measuring device of scarce filter tip.

The on-line measuring device of described a kind of cigarette Zhi Songtou of the utility model and scarce filter tip comprises that cigarette props up sense channel, props up at cigarette the selection drum is installed in the sense channel, is selecting that a scarce filter tip sensor and a pine detecting sensor are installed on the drum.

As the improvement of the utility model, lack the filter tip sensor and be installed in the both sides of selecting drum respectively with a pine detecting sensor.

The utility model adopts a scarce filter tip detecting sensor of photo-electric and a condenser type pine detector to the online detection of cigarette Zhi Jinhang; Pine head and scarce filter tip sensor are carried out signals collecting and make judgement according to synchronizing signal by microprocessing systems, defective cigaret is rejected through rejecting on the drum after the corresponding time-delay.The utility model is designs simplification not only, and has improved the accuracy rate that detects.

Fig. 2 is the structural representation of the utility model.

The specific embodiment

As shown in Figure 2; The on-line measuring device of described cigarette Zhi Songtou of the utility model and scarce filter tip; Comprise that cigarette props up sense channel 4, prop up to be equipped with in the sense channel at cigarette and select drum 5, a scarce filter tip sensor 6 and a pine detecting sensor 7 are installed respectively in the both sides of selecting drum.

The utility model provides the thinking and the implementation method of the on-line measuring device of a kind of cigarette Zhi Songtou and scarce filter tip; Concrete application approach is a lot, and the above only is the preferred implementation of the utility model, should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also make some improvement, these improve the protection domain that also should be regarded as the utility model.

Claims

1. the on-line measuring device of a cigarette Zhi Songtou and scarce filter tip; Comprise that cigarette props up sense channel (4); Prop up to be equipped with in the sense channel at cigarette and select drum (5), it is characterized in that lacking a filter tip sensor (6) and a loose detecting sensor (7) selecting to install on the drum.

2. the on-line measuring device of cigarette Zhi Songtou according to claim 1 and scarce filter tip is characterized in that lacking filter tip sensor (6) and a pine detecting sensor (7) is installed in the both sides of selecting drum respectively.
