    The seam of the tubular wrapper for the rod-like filler of tobacco or filter material in a cigarette or filter rod making machine is heated by a first heating element during acceleration of the machine from zero speed to normal operating speed. When the machine reaches the normal speed, the seam is additionally heated by a second heating element whose heating action is more pronounced that that of the first heating element. The first heating element is caused to engage the moving seam when the first increment of adhesive film, which is applied to one marginal portion of the wrapper by a paster, reaches the first heating element. The second heating element is moved into engagement with the seam when the RPM of the prime mover for the filler transporting conveyor reaches a preselected value. Both heating elements are disengaged from the seam in response to deactivation of the prime mover with a delay which corresponds to the interval elapsing between deactivation of the prime mover and the transport of last adhesive-coated increment of the one marginal portion to a position of register with the first heating element.

    one
    The invention relates to the production of cigarettes and can be used in the tobacco industry.
    A cigarette making apparatus is known, comprising a device for forming a tobacco rope, for wrapping the latter with a strip of cigarette paper, for applying glue to the edge of the strip and for heating the seam formed when gluing the ends of the strip 1.
    However, this device does not allow the production of high-end cigarettes due to the searing of the bundle seam when heated during device startup.
    The aim of the invention is to improve the quality of cigarettes by eliminating the possibility of scorching the seam of the rope.
    For this, heating of the seam of the rope is carried out in two stages so that the first heat source is activated at the stage of the rope run, and the second heat source is connected depending on the predetermined speed of the rope.
    In the proposed device for the manufacture of cigarettes a device for heating the seam consists tto
    at least two horizontally arranged plates, each of which is mounted with the possibility of vertical movement from an individual drive, wherein the drive of one of the plates is interlocked with a sensor for the presence of a harness, and the other with a sensor for the speed of movement of a harness. In this case, the drive of each plate is pneumatic.
    Fig. 1 schematically shows a device for the manufacture of cigarettes .; general form. Fig. 2 shows a switching circuit of a device for heating a seam formed by gluing the ends of a strip.
    The device (see Fig. 1) includes a device for forming a tobacco bundle in the form of a channel 1, a device 2 for wrapping the tobacco bundle 3 with a strip of cigarette paper 4j, a device 5 for placing glue on the edge of the strip and a device for heating the seam formed by gluing the ends of the strip .
    Channel 1 has a perforated bottom 6 through which breathable tobacco ribbon 7 can be inserted, on which a tobacco rune is rubbed and tobacco is formed
    flow {not shown), for which under the bottom of the channel there is an intake chamber 8 connected to a system for air suction (not shown).
    The forming wheel 9 has on its circumference a U-shaped and perforated along the bottom groove associated with the dTcoca system for collecting tobacco flow from the tobacco ribbon. The ripper 10 serves to remove the excess in the tobacco flow on the forming wheel. And to form the tobacco tow 11.
    The conveyor 12 is also provided with a suction (not shown in the drawing) and serves to remove the tobacco rod 11 from the groove of the forming wheel 9 and deposit it on the fed strip of cigarette paper 4 from the reel 13 that passes through it. printing device 14 and fed to a formatted tape 15.
    Device for heating the seam (see Fig.2) consists of at least. Of the two horizontal plates 16 and 17, each of which is installed with the possibility of vertical movement from an individual drive, the drive plate 16 is interlocked with the sensor 18 having a harness, and the drive plate 17 - with the sensor 19 speed of moving the harness. .
    The format tape 15 transports the tobacco bundle 11 and the strip of cigarette paper 4 through the tobacco bundle wrapping device 2, in which the cigarette paper strip 4 folds around the tobacco bundle 11 so that there is still a crush on which glue is applied with adhesive 5 for applying glue. Then this glue line is dried using a device for heating it. The cigarette bundle thus obtained is cut with a knife 20 into separate cigarettes which are pushed into the folding drum 22 by the accelerator 21.
    The control of the seam heating device is carried out as follows.
    Both plates 16 and 17, the latter of which has a higher heating power, using drives that are made in the form of pneumatic cylinders 23 and 24 of double action, respectively, can move upwards and VNII in the direction of arrows 25 and 26. On pistons 27 and 28 of the cylinder alternately acts compressed air supplied by the source 29, respectively, through (4/2) directional valves 30 and 31 with a magnetic drive.
    For controlling the valves 30 in the circuit there are an amplifier 32, a memory block 33 with an input a for a set, an input b for erasing and an output c, a sensor 18 with a counting input o associated with a decoding unit 34 an input b for control, an input for reverse set and output d, as well as element 35 (UND) with inputs CL and b and output c, and to input o, signals from the clock sensor can be supplied as clock drive 36 and injected from the main drive of the device (not shown). The proximity transmitter 37 and the input b can be given a release signal from the fixture 5 for applying glue to the edge of the strip (see Fig. 1).
    To control the valve 31 for the plate 17 in the circuit there are an amplifier 38, a memory block 39 with an input a for dialing, an input b for erasing and an output c, a sensor 19 for moving the harness (Schmidt trigger) with an input ct and an output b for potentiometer 41 for setting, limit value, resistance 42, analog-to-analog converter 43 with input cu. and output b, element 44 (UND) with inputs CL and b. and output c, and the signal from sensor 45 can be connected to input cL to control the lower positions of the plate 16 when in contact with the harness, and to the input b and signals from the same can be summed. a stroke disk 36 and a proximity initiator 37.
    . For the reverse dialing of the sensor 18 and for erasing in blocks 33 and 39 of memory, there are a block of memory 46 with an input of O for dialing, an input of B for erasing, and an output of c, a counter 47 with a counting input of a, cor. t with decoding unit 48, control input b, input c for inverse dialing and output d, a also element 49 (UND) with inputs O and ib and output c. The inputs of the element 49 can also be supplied also from the tact disk 36 and the proximity actuator 37, the input B can be output from the device 5 for applying glue and to the input c for reverse dialing, as well as the input B for erasing the counter 47 and the memory unit 46, respectively, may provide a return dialing signal, for example, by re-enabling the device.
    The operation of the plates of the seam heating fixture is carried out as follows.
    In the case of the connection of the glue application device 5 during the automatic control of the start, a release signal is issued to the input element 35, the input of which also receives clock signals from the clock disk 36 and the proximity initiator 37. Thus, the element 35 sequentially turns on the clock signals, which are entered through the input from the sensor 18.
    As soon as the sensor 34 chisel-mounted 34 unit, which corresponds to the path between the cigarette gut 11 between the glue application device 5 and the plate 16, is reached, the output of the sensor 1.8 appears on the input to the memory block 33 on The output from which also appears is a signal that ycs in the amplifier 32 and activates the valve 30. The valve 30 switches so that air is removed from chamber A of cylinder 23, and air is supplied to chamber b, the piston 27 moves down and there is no plate 16 to pass To the cigarette harness. .- With the plate 16 being lowered through the sensor 45, the signal is transmitted to the element 44, which simultaneously receives clock signals from the clock disk 36 and the proximity initiator 37 so that corresponding clock signals appear at its output, which are fed to the analog-to-analog converter 43 At its output, an analog signal (in the form of voltage) corresponding to the speed reached by the device is obtained, which through the resistance 42 is supplied to the comparison unit 40, and has a signal (in the form of voltage) corresponding to the predetermined speed And As soon as the device for making cigarettes reaches a predetermined speed, and thus the speed of the harness, respectively, the signal appearing on sensor 19 triggers the latter. And it issues an input signal o for the memory set in memory block 39 the output signal of which through the amplifier 38 switches the valve 31. Owing to
    A cylinder 24
    This air is removed from the chamber, and into chamber B is brought in, while the piston 28 also moves the plate 17 to its working position relative to the harness 11, which now receives all the heating capacity available.
    When the device is installed, both plates J6 and 17 are retracted from the bundle due to the fact that when the device is installed or when the device 5 for applying the adhesive is turned off, the disconnection signal together with the clock signals is fed to the inputs Of TA TA of the element 49. Thus, the series-connected element 49 outputs clock signals to counter 47, which, when it reaches a pre-selected value, outputs a signal to memory 46, which is turned on in series, turning its output signal back (turns sensor 18 to zero and clears money at-33 and 39. In these blocks vyodah signals disappear
    Both magnets of the valves 30 and 31 are lowered, and the valves are switched to their zero position, with air being removed from the chambers B of the cylinders 23 and 24 and entering into their chambers. A. Both porsyne 27 and 28 are then withdrawn from both the plate 16 and 17 at the same time from the cigarette tow. When the device restarts immediately, the return dialing signal is output to the counter 47 and the memory block 46.
    0 or erase.
    The proposed device for the manufacture of cigarettes as compared with the known one provides an improvement in the quality of manufactured cigarettes, since
    The 5 stages of launching the device to the seam of the rope are supplied with such heating power that it is reliably sealed, but does not burn at a relatively low feed rate of the tow, and in the areas of higher feed rates that are reached relatively quickly, high power is immediately directed preheating to reliably seal the seam at a given production speed, Meanwhile, at the slower stages of starting the transitional stage from starting to normal production speed, as well as at full production speed, a tow of high quality seam
    0 and by eliminating weld defects, production waste is reduced when cigarettes are manufactured at the start-up stage. ..
