Description

The cigarette quality testing device of a kind of adaptive Great Wall board cigarette unit

The utility model belongs to cigarette and props up online quality detection device, and the cigarette that particularly relates to the Great Wall cigarette unit that adaptive Mo Linsi company manufactures and designs for China props up the detection device for eliminating.

China production of cigarettes producer, majority has Mo Linsi (MOLINS) company to manufacture and design for China and nine (SUPER9) cigarette that surpasses of called after Great Wall board connects and chews unit, this production technology has transferred tobacco machine makers such as Jianchang, China Xuchang, China's model is YJ-15, it is configured in filter and chews the cigarette quality testing device that is hinged with on the part PA9, because the defective of device own, the fault rate height, adjust complicated, service efficiency is low, and stops using mostly, causes bear, lack and chew, the cigarette of gas leakage can not be rejected and be had a strong impact on quality cigarette, or found bear by the downstream packing machine or be considered as lacking and whole bag is rejected, cause unnecessary economic loss.The defective that the last cigarette of PA9 props up checkout gear is the common fault of Mo Linsi company multiple model cigarette machine, its last generation product MK-9, MK-96 and next generation product P ASSIM exist equally, its underlying causes is that Mo Linsi company produces existing more than the 160 year history of cigarette machine, it detects the cigarette quality method and follows self traditional system, be to use detection of negative pressure always, though the Englishman is also clear and admit that also the effect of detection of negative pressure is bad, for service companies prestige, inconvenience is the change system thoroughly.Thereby to transform the cigarette machine of import now, be exactly will be with the frame for movement of producing by the detection of negative pressure method, prop up under the constant situation of transmission relative dimensions at cigarette, change the structure that detects by malleation into, this than directly by malleation detect manufacture voluntarily more complex, this is one should look after original frame for movement, size and layout, few as far as possible the change, installation dimension is very compact, thoroughly change the particular design and the transformation of another opposite detection architecture again into, the inventor once transform detection of negative pressure as malleation and detects on last generation product MK-96 machine CID-6, and actual motion is respond well, produce in batches, its number of patent application is 94226603.X.Great Wall cigarette machine cigarette props up and detects the subject matter that exists is that it detects principle to the production of cigarettes environmental inadequacies; rather than principle itself has problem; its cigarette props up and detects mechanism is to prop up sealing according to cigarette; only stay the pipe tobacco termination to lead to atmosphere; in annular seal space, impose negative pressure then; measure its gas permeability (MOLINS company is referred to as dilution factor) with pressure sensor; because particle dust is extremely many in the cigarette unit surrounding environment; when the shutdown negative pressure progressively disappears; negative pressure makes all pipeline eyelets that dust suction testing process negative pressure exists in the air; long-term deposition, resistance to suction constantly increases, and must form obstruction at last.Next is to reject the control parameter, adjusts complicated, not directly perceived.

The purpose of this utility model is exactly thoroughly to eliminate the obstruction root of machine cigarette quality test section, Great Wall, providing a kind of can not stop up, adjust intuitive and convenient, can mate with PA9 again, can substitute original cigarette and prop up the novel cigarette quality testing device of test section, that is to say, original cigarette being propped up mechanical drum, circuit and the gas circuit of test section transforms, detect the gas leakage principle with malleation, add nominal sensor again and detect bear's (the cigarette termination lacks pipe tobacco) cigarette, utilize original rejecting high-speed electromagnetic valve, the electrical control circuit that configuration adapts, and form new system.

The purpose of this utility model is achieved in that 1. negative inspiratory pressure being detected cigarette props up gas permeability and change malleation into and blow to detect cigarette and prop up gas leakage, avoid dust deposit in the pipeline eyelet, because malleation is to atmospheric exhaust rather than suction, and the malleation source of the gas is the clean air source of treated mistake, and this has just fundamentally eliminated the obstruction root; 2. the inspiratory capacity (measuring resistance indirectly with pressure sensor) and logical total air inflow with filter tip (also being to measure resistance indirectly with pressure sensor) of coated papers propped up in original detection by cigarette.Calculate its percentage and be called dilution factor, surpass or be lower than a certain value and then think bad cigarette (poorly sealed, gas leakage or too tight), calculate the conversion complexity, thereby adopted complicated software for calculation to finish.Whether the utility model only detects gas leakage, also measures positive air pressure indirectly with pressure sensor, when (one) short cigarette occurring; (2) lacking filter tip or yew paper bag wraps up in not tight; (3) the damaged or parcel of cigarette paper does not sternly wait and forms gas leakage, and then malleation reduces and found rejecting, but its rejecting amount control simple, intuitive rotate positive pressure regulating valve change source of the gas malleation and can finish the task of adjusting.3. the detection of nominal cigarette, original device uses optical detection principle, effect is generally not good because dust intercepts light, the utility model then must add nominal detector in addition, because it is little to detect the drum surrounding space, can not load state's foreign cigarette machine bear commonly used and detect capacitance sensor, so should be the sensor miniaturization.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is according to the detection drum assembling schematic diagram that the utility model proposes.

Illustrate according to concrete structure parts and the front and back annexation thereof that the utility model proposes below in conjunction with Fig. 1.Detect on the drum at former PA9, two end faces 1 (being former machine part 54011.309CARRIER GEAR) and 3 (being former machine part 540233.400VALVE RING) of detecting drum among Fig. 1 are changed a social system, its transformation of the way back profile shown in accompanying drawing one, on the drum 56 detect boring ratio original position bore dias and will strengthen, be about 4.8mm.The local gas circuit of changing, provide to detect and use the malleation source of the gas, install the sealing cigarette additional and prop up the porose detection rubber cap in center, two ends (former rubber cap only blocks the filter tip end), increase the pressure sensor of adaptive new employing and the automatically controlled circuit board of nominal detecting sensor, its control output is connected to the mounted high-speed electromagnetic valve of former machine, rejects defective cigarette by air-flow in good time and props up.

Just changing a social system key component below is described further in conjunction with the accompanying drawings.

From figure one, can find out the malleation gas circuit circulation path after implementing to change a social system, the part of not specified (NS) among the figure, introducing as the malleation source of the gas, pressure sensor and capacitance type sensor and all be common known technology than lock-out pulse etc. for it provides voltage ratio that power supply and output voltage amplitude differentiate are generally understood high speed cigarette machine common circuit person and can both be designed voluntarily.The starting point of the transformation of the way is exactly a gas-distribution pipe introducing malleation source of the gas behind the slave, be added to into tracheae 2 (seeing figure one) by flexible pipe, pipeline by graphite slider 4 inside arrives air inlet pipe 6, promptly guide to the centre bore of the detection rubber cap 6 that can cover the pipe tobacco termination, air-flow can pass the cigarette Zhi Ranhou that detects in the drum from rubber cap 7 centre bores to venthole 8, enter second graphite slider 9, through pressure sensor 10, pressure sensor is the integrated strain bridge of silicon chip, and when the bridge circuit two ends applied positive and negative 5 volts, air pressure made electric bridge one arm resistance variations, respective output voltages changes, after this voltage amplification filtering, select cigarette by lock-out pulse and prop up and be in the gas pressure value in following time, differentiate through voltage comparator then, be higher than certain value and represented cigarette, be lower than certain value and represent cigarette to prop up poorly sealed gas leakage, thereby talent forces down, should reject.As for scarce filter tip, the inevitable institute of short cigarette measuring pressure is lower, must be at the row of rejecting.If the rejecting amount is too much or the rejecting amount is too little, want to improve the detection quality index, at this moment the reference voltage of adjusting voltage comparator is intuitively not inconvenient yet, can adjust the pressure regulator valve of air inlet pipe, the air pressure that applies increases or reduces, and the air pressure after then propping up by cigarette also will increase and decrease in proportion, and this just equals to have adjusted comparison reference voltage, because air gauge indication is arranged, so unusual intuitive and convenient.

As for nominal cigarette, not necessarily gas leakage, in order to reject, must add nominal detector in addition,, capacitance type sensor is installed in the termination of detecting certain groove of drum, acquire a certain degree as bear, just output voltage drops to certain value and is also rejected, and its signal (comprising the gas leakage signal) of delivering to magnetic valve props up the figure place of lock-out pulse clock movable sensor to magnetic valve with shift register by cigarette, could accurately reject the bad cigarette of being found.

Among the figure one, drum is driven by internal tooth, and 56 rubber caps are arranged, and then rousing corresponding to inspection has 56 cigarettes to be detected to prop up, and graphite slider 4,9 and the airtight sliding fit of drum end face pass through spring compression by the axostylus axostyle that is fixed on the protective cover, make it air tight.For this cover malleation tracheae and slide block is installed, protective cover has been opened installing hole, and remainder does not change.

Device adds to detect to be differentiated, reject electrical control circuit and form mode for two kinds by main dependence software and the main hardware that relies on, PA9 is originally and relies on software to finish, if think motionless software, then need only send one to characterize normal dilution voltage to the corresponding output of original sensor, just give illusion of computer CPU, dilution factor is normal all the time, computer is not sent out and is rejected order, and the rejecting of bad cigarette is finished by the automatically controlled plate of hardware logic fully, can indiscriminately imitate the automatically controlled circuit board of having produced use in the MK-96 machine CID-6 transformation in batches, rely on software mode then will revise PA9 Central Plains computer correspondent section program, only will leak gas signal and nominal detection signal done to send the corresponding interface after the adaptation processing, finish differentiation by computer, and send and reject order.
