    The wrappers of filter cigarettes or analogous rod-shaped articles which constitute or form part of smokers' products and wherein portions of the wrappers have perforations are tested while moving sideways in the flutes of an endless conveyor. The testing involves establishing a less pronounced pressure differential between the interior and exterior of unperforated wrapper portions and a more pronounced pressure differential between the interior and exterior of perforated wrapper portions. An electropneumatic transducer generates first signals which denote the rate of fluid flow through the perforated and unperforated wrapper portions. Such signals are compared with first and second reference signals which respectively denote the maximum permissible and minimum acceptable permeability of wrappers, and the articles wherein the permeability of wrappers exceeds the maximum permissible permeability or is less than the minimum acceptable permeability are segregated from other articles.

    The invention is suited to a method for controlling sterilized tobacco products having a zone of required permeability during their transport transversely across the axis along a given path by creating an alternating cross-section between the shells and space and space outside of the center and the craze where they are at their craze. signal, as well as devices for the implementation of this method, and can be used in tobacco equipment, as well as a known method. To) B1 control rod and tobacco fiasHbDC deltly, comprising forming conductive CONTINUE 1Yes pressure in the chamber "rejection w4 ektnyh tobacco fj. A device is known for controlling slender-shaped products, including an exploratory chamber, an air supply device, a transducer and an actuator, mechatzm, which is used for rejecting defective tobacco products vii 2. The disadvantage of this method and the device is that it builds on the pressure between the space of the cigarette shell to the space outside this rim, and E1he the pressure drop is constant throughout the entire roll area of the cigarettes. In addition, the above method and device can only be used, and cigarette tobacco products with unacceptably high air permeability of the casing. Closest to: the proposed method is a contact {hm1 rod-shaped tobacco and the building, providing for the formation of a pressure differential outside the zone of the desired air permeability p From the above source also known device d; The implementation of this method of walking; It contains a camera that serves to locate tobacco and RS, with a cathode gauge, a measuring instrument, a reference signal generator, a threshold element, a control unit, and a shift register. The disadvantages of the tweeter: the TID method and device is that they control the shell of the rod of shaped tobacco products in; they are transported along the transverse axis, on the one hand, to undesirable air permeability, and on the other hand, not to achieve the desired air permeability shell zone. The purpose of the invention is an accurate control. This goal is achieved by the fact that, according to the method of controlling rod-shaped tobacco products, providing for the formation of a pressure drop outside the zone of the desired air permeability, a pressure differential is created in the zone of the desired air permeability and the difference between these differences is determined, and the control is carried out according to the result of the obtained difference upper and lower limit values. This goal is achieved in that the device for monitoring rod-shaped tobacco products, containing a chamber for accommodating tobacco products, a source of compressed air, a measuring device, a reference signal adjuster, a threshold element, a control unit and a shift register, is provided with an additional reference sign generator. The noporoBbUvi element and the mechanism used to reject defective tobacco products, and the chamber used for housing rod-shaped tobacco products are divided into two parts, each of which, via a pipeline and a choke, are connected to the source of the szltovoz spirit, while the threshold elements are connected to the executive mechanism by means of the logical elements OR and AND. FIG. Figure 1 shows schematically the attachment of filters for manufacturing equipment with a filter; FIG. 2, a cut-out of the control drum is mashknny for attaching F1 liter of FIG. 1 in section; on . 3 - section AA on. 2 (part of the control drum); in fig. 4 is a control circuit for finding defects in tobacco products for contpoJ: bHoro of the drum of FIG. 2 and 3. In the MAX S filter attachment box, the input drum 1 delivers manufactured cigarettes to two folding drums 2, which disassemble incoming cigarettes that are inferior, and in rows of two brushes with the space between the cigarettes are fed to the assembly drum 3. Daddies of filters come in from the accumulator 4 to the cutting drum 5, are cut by two disk knives and 6 into double-length filter sticks, assembled on a pull-off drum 7, shifting the drum 8, are leveled into a row of filter sticks lying one after the other and the accelerated 6apa6aiiOM 9 are placed in the intermediate spaces between the cigarettes on the assembly drum 3. The cigarette-filter-cigarette groups are shifted so that the components closely adjoin each other. Then they are transferred to the transfer drum 10. With the help of a roller 11 from the reel 12 with a roll of paper, a strip of 13 covering paper is folded. A strip of covering paper is guided around a sharp-edged pre-folding device 14, smeared with glue by the glue dispenser 15, and a knife 17 is cut on the spreading paper roll 16 to cut groups of paper onto the transfer drum 10. the cigarette filter is a cigarette and on the mobile drum 18 is wrapped with a coil with the winding lever 19 around the cigarette-filter-cigarette groups. The finished groups of double filter cigarettes are fed through the dryer drum 20 to the cutting drum 21 and, on it, in the middle of cutting the filter rods, become ready-made individual cigarettes, while the defective filter cigarettes are discarded. Together with the transfer drum 22 and the assembly drum 23, the inverting device 24 overturns one row of filter cigarettes and simultaneously transfers them to the row of filter cigarettes passing the transfer drum 22 and the assembly drum 23 unturned. Through the control drum 25, the filter cigarettes reach the discharge drum 26, on which the filter cigarettes are checked on the heads before scavenging. The folding drum 28 acting together with the brake drum 27 places filter cigarettes on a strip 29 for stacking. X -. On the hollow axis 30, a drum housing assembled from three parts 31-33 is rotatably mounted. On the front side, on the parts 32, there are fastened recesses 34, disks 35, forming receivers for filter cigarettes. Item 32 has tray-shaped chambers 36, each of which is divided into two chambers 37 and 38, also having a notch 34 with a bar 39 at a junction between the tobacco stick and the filter of the filter cigarette filter section adjacent to it. The sheets of paper covering the filter cigarettes have a zone of desired air permeability. formed by a series of holes. They may already be in cover paper or punctured in L11 overhead paper. Between the disks 35 there is a sealing means (second sealing means) in the form of a fixed lid 40 made of sheet, which closes the 37 U 38 when they are circulated temporarily to a small gap. As a means to create; various pressures in chambers 37 and 38; a duct 41 is installed. For this floor, the DA axis of circular column 42 is divided into two chambers 43 and 44, which are associated with pressure ejection. The chambers 43 and 44 have a device for connection in the form of a control or 46 and chambers 37 or 38 using the corresponding channels 47 and 48 in the drum housing. To pressurize the inside of the cigarette shells with the filter and / or to attach to the pressure-sensing measuring device, the drum body lia on one side has sealing means (first sealing means) in the form of a disk 49, which is part of the drum housing part 31. The disk 49 has holes 50 passing to the cavities 34 of the disk 35. A control ring 51 mounted on the wall of the mashina with a device for mounting the wheel in the form of a control slit 52 refers to the disk 49. On the other side of the drum body the disks 34 of the disk 35 are controlled in the direction of the double arrow, a compaction device (first means of a vacuum) in the form of holes 53 or 54, located on the disk 55, which is an integral part of the drum body part 33. The control ring 56 fixed on the hollow axis 30 is associated with the disk 55 and has a device for connecting it in the form of a control bar 57, which also serves to connect to a pressure source and / or measuring device for measuring pressure differences Iy. From the output side of the source 58 compressed: air of the control air through the duct 59, having the installation fan 60, from the pre-pressure epithel 61 and the throttle 62j is fed to a cigarette with 4 pcs. Compressed air passes through the filter cigarette and exits through the Uyuzch -Home 63 ({extending from control slot 57, anvil) ring 56), throttling throttle 64, which is connected to a measuring box 65 for measuring pressure, for example, an automatic spring meter, and casting a difference in pressure measurement unit 66. On the input side, the source 58 of the compressed air 1 is connected to the duct 41, for which oHs therefore, among other things, a source of reduced pressure:., The suction pad 67 diverges from the Boaj header 68 and 69, which enter the chambers 43 or 44 a hollow DZ axis and which each device has an L1H1 valve 70 Wsh 71 and a measuring device 72 or 73 pressure measuring device, a measuring device (66 W1vmaht device (electrically-electr1; "ес измерит measuring measuring transducer 74 to which two sensors are connected in parallel behind it nojxjroBbix elements 75 and 76.

The actuator has an amplifier 84 and a electro magnetic valve 85, which is located in the connecting air source 86. The output of the logic circuit 80 I is connected to the shift register 82, | Pr1SodshuCHIM per sensor doubled / 1 81 clock pulses with a blow nozzle 87 of the breeder 88, This blow nozzle 10 33 87 is located at the discharge fepaudHa 26, the impeller operates as follows. Correspondingly, the pressure chamber 5 under pressure 5 under sheet metal, with reduced pressure 5, and due to the corresponding adjustment of the installation valves 70 and 71 in the air ducts 68 and 69, much lower pressure is created in chamber 37 than in chamber 37, through control slot 52 from duct 59 The sloping air is blown into the inside of a filter-tipped cigarette, which comes out of and through the control slot 573 which is shorter than the pressure interval between the filter-tipped cigarettes on the control drum 25, enters the air duct 63, From "The test transformer continuously sends an appropriate electric pressure to the threshold element 75 and 76, which is currently in the fire control circuit 63, sending the output signal to the OR logic circuit 79 and thus to the VO I. logic circuit if received in the HVI signal above the transmitter signal 77 reference signal or below the signal of the additional setter. 78 reference signal. Through a logic circuit 80 I, as well as a sensor 81 clock pulses, the control signals are analyzed in accordance with the right time point of the control center. It is at the time when the filter cigarette is connected to the controller that went 57, If at this point in time the logic circuit 79 OR sends the link to the logic circuit 80 AND, the filter cigarette has either the cordless plug of the shell at the site of the palschka of tobacco, or with the stoic, the small air gap of the covering paper, i.e., defective Persian {Yuraisho. Due to the different pressure conditions in the chambers 37 and 38, the holes in the sheet metal of the covering paper are tested with significantly higher sensitivity than the air permeability of the shell material of the tobacco stick. The average air permeability of the shells of several filter cigarettes is read on a pressure sensor measuring instrument 65. If the filter attachment machine is operating at a nominal rate, in which J, for example, a maximum of 4000 filter cigarettes per minute, it is possible, since the inertia of the pressure measuring device 65 is a constant, even the number of filter cigarettes is valid, the displayed value of the pressure measuring instrument 65 is. Separate analysis of the control signals through the measuring device 65, on the other hand, prevents the defective cigarette filter cigarettes from being further processed, so that the output signals of the AND logic circuit 80 generated by the defective filter cigarettes, t. e. by such filter cigarettes, the shell of which has too high air permeability in the tobacco stick section, or whose openings in the sheet of covering paper have too little air permeability. Mocib is fed to the shift register and it shifts synchronously with the movement of the transport of the corresponding filter cigarette, so that when the corresponding filter cigarette reaches the winding nozzle of the discharge drum 26, the solenoid valve 85 is activated according to the beat, due to which air blows out of the blown nozzle 87 and the filter cigarette is blown out of the selected the drum 26. As a result of using the invention, the accuracy of the control will increase, since in one process of control it can be set as defects in the shell, i.e. too much lsha breathable membrane in general and the defect in the membranes vozduhopronknaemostn zone.
