The disadvantage of the known devices is the damage of cigarettes when contacting them with mechanical parts, .. The purpose of the invention is the elimination of damages. In the moving flow of cigarettes when contacting them with mechanical parts. This goal is achieved by the fact that in a conveyor system for transferring a mass of rod-like products, mainly cigarettes arranged horizontally and pa; parallel to each other, from a machine for manufacturing them to a packaging machine containing a conveyor for transferring products in a direction transverse to their axis several channels connected to one another, and a control device for determining the number of products in a given position of the conveyor, including several photoblocks, each of which has a light source for a light beam and a receiver located at a certain distance along the line of the light beam for the light beam and outputting the output signal, and an electronic circuit for controlling the conveyor drive, respectively, two vertical plates are installed at the test position A number of light sources are laid on one of the plates, and one: vertical p; receivers respectively located on another plate. In addition, one vertical plate 1 has several rows of light sources, and the other, respectively, several rows of receivers, with the light sources and receivers of one row being shifted vertically relative to the light sources and receivers of the adjacent row. The rows of sources, light and receivers are inclined relative to the vertical. FIG. 1 schematically shows a conveyor system, connecting two production machines with a packaging machine; .on FIG. .2 - section .A-A.In an enlarged scale of the detail shown in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 - a modified version of the de; The hoists shown in FIG. 2; in fig. 5 is an enlarged view of the detail shown in FIG. 1; FIG. b - the circuit of the electric circuit forming part of the conveyor system. The cigarette making machines 1 and 2 are connected to the packaging machine 3 by a conveyor system 4 formed by a group of channels along which the cigarettes stacked one upon another move continuously transversely to their longitudinal axis. The channels are formed by branches of endless belts and in curved parts by belts aggregates with rollers or pulleys. The conveyor system 4 leads to production machines 1 and 2 through horizontal channels 5 and 6. 1 The latter are connected by curved channels 7 and 8, followed by vertical Channels 9 and 10 to a common horizontal pipeline, bounded from left to right by three channels. 11 - 13 ( Fig. 1). Channel 11 passes between the vertical feed pipe 14, the storage bin 3 of the packaging machine 3, and the upper or output end of the vertical channel 10, channel 12 is located between the output end of the channel 10 and the upper OR output end of the vertical channel 9, and channel 13 between the output end of the vertical channel 9 and storage 15 s, variable volume to compensate for any imbalance of the working speeds of production machines 1 and 2 and packaging machine 3. In the zones where channels 9, 12 and 13 and channels 11 and 12 converge, two test points are installed x 16 and 17 fvn change detection devices
    In the number of cigarettes. Two devices 18 and 19 of the mentioned type are installed between the channel .5 and the curved channel 1, and between the channel 6 and the curved channel 8, respectively. The convergence zones of channels 9, 12 and 13, formed by three pairs of belts 20 and 21, 22 and 23, 25, are shown in FIG. 2 and 3. Each of these belts runs endlessly around end rollers 26, whose axes 0 are perpendicular to the plane of the pattern.
    At least one roller of each belt is rotated around its axis by means of a drive (not 15 shown). The control device 16 operates in a vertical recess 27 (well), which closes the channels 12 and 13 and is centered with the channel 9. The recess or well 20 27 is open at the top, with its lower end communicating with the inside of the conveyor system 4 and all sides. facing channels 12 and 13,. . and connected by walls 28 and 29 of pro. 25 light-emitting material. On the outside of the recess 27, on two walls 28 and 29, plates 30 and 31 are fixed, provided with holes 32 and arranged symmetrically around an intermediate vertical plane between the JQ. mentioned walls.
    Holes 32 (Fig. 3) in plate 30 are centered at a constant time along two vertical rows, 35 with five holes each. These rows are located in a checkerboard vertically one above the other, so all 32 holes have one. There is a zigzag arrangement with Q ago, which is half the aga of individual rows. The holes in the plate 31 (not shown) are arranged in the same way as in the plate 30. The control device includes an electrical circuit (FIG. 6) described using the example of the control device 16, which controls the operation of the channel 13 connected to the compensating storage 15.
    The holes 32 in one of the two 50 plates, for example in the plate 30, serve as a support for the photoemitter. elements, and the openings 32 in the plate 31 are designed to receive photosensitive Elements, each of 55 of which is installed in the path of the corresponding photo-emitter element. In the proposed construction, the photoemitter elements consist of infrared emitting diodes 33 Q, and the photosensitive elements are phototransistors 34, the diodes 33 are connected in series and powered by a DC generator 35.
    The current is supplied through the circuit of the current stabilizer 36 and the safety switch 37. The switch 37 is designed to turn off various installation machines when one of several diodes 33 goes out of order.
    The rays emitted by each diode (schematically indicated by the arrow f are directed towards the corresponding phototransistors 34 connected to earth through the respective emitters. The collector of each photo transistor 34 is connected via a resistor 38 to the positive pole 3 of the DC generator and also directly connected to an input of an amplifier 40 having a coupling resistor 41.
    The output of each .40 amplifier is directly connected to the control input 42 of a solid-state switch, shown schematically as a normally open connecting contact 43 between input 44 and output 45. Inputs 44 are connected in parallel via resistors 46 to the positive pole of the DC generator, and terminals 45 to the input work amplifier 47.
    The operational (operational) amplifier 47, to whose input a voltage is applied, adds the voltage to a gain that is controlled by a feedback resistor 48. The output of the amplifier 47 is connected to the input of the second circuit of the adder, represented by the working amplifier 49. The working amplifier 49 with its gain factor defined by the feedback resistor 50 algebraically folds the reference voltage with the output voltage of the amplifier 47.
    The same amplifier 49 controls the operation of a circuit of a known type, designated 51, to drive a bi-directional motor 52 which drives the conveyor means for the channel 13.
    A circuit consisting of switches 43, working amplifiers 47 and 49 forms a control circuit for circuit 51. A voltage is applied to the latter, which in terms of absolute value and sign is a function of the number of phototransistors in their conducting state, t . rays from the corresponding fato-emitter elements fall on them.
    The control device 16 in conjunction with the installation works as follows.
    If the working speeds of production machines 1 and 2 and the packaging machine 3 are properly balanced. then, compensating storage 15 is not needed. Under such ideal operating conditions, the level of cigarettes in the recess 27 is such that the motor 52 for driving the belts 24 and 25 is kept in a locked state by an electrical circuit. Cigarettes are stored in storage 15 for the entire time required to establish balanced levels inside recess 27 or, in other words, until the output voltage of work amplifier 49 becomes zero. If, due to the stop of the packaging machine 3 or a decrease in the operating speed of the machine, the level of cigarettes inside recess 2 is enlarged, other phototransistors 34 are not illuminated besides five phototransistors located below the equilibrium line. Consequently, a negative voltage is established at the output of the operational amplifier 49, whereby a negative reference voltage prevails at the output voltage of the amplifier 47. This voltage is supplied through the circuit 51 to the motor 52, which rotates in the opposite direction, causing the tap of the belts 24 and 25 moving in the direction of the arrow. at a speed proportional to the number of unlit phototransistors 34 above the equilibrium line. The cigars are sent to store 15 until a balanced level is again established in recess 27. FIG. 4 shows a control device 16 installed in an area where channels 9, 12 and 13 converge. In this case, the plates in which the photosensitive and photo emitter elements are placed are fixed on the walls of the recess or well 27, located perpendicular to the walls 28 and 29 (“and only one plate is visible in FIG. 4). The corresponding support wall is designated by the positions 53 and 54. Consequently, the control operation is carried out parallel to the longitudinal axis of the cigarettes. Holes 32 in the plates 53., where the photoemitter and photosensitivity are located; These elements are arranged in vertical rows with five holes in each row, and they are displaced from one another, unlike in the previous case, when they are arranged in two rows. The plates 55, in which photo-emitter elements are installed. And photosensitive elements. (Only one is shown), are fixed on opposite side walls 56 of one of the horizontal ones. channels of the conveyor system 4, and not on the wall of the recess or well. In contrast to the example described, the control device, the plates 55 of which constitute a part of it and are indicated by the position. 57, determines the mass level of cigarettes moving along the channel, and not the mass of cigarettes that move in the vertical direction between the walls of the well. In the latter design, the openings 32 are located one at a time on an inclined line. In addition, when the sensitivity of the monitoring devices is not required, the apertures 32 can, for example, be arranged along a single vertical line. In the latter design (not shown), two plates 30 and 31, containing photoemitters and photosensitive elements, can be installed at different levels, rather than at the same level (Fig. 2). In this case, the light rays from the photoemite of the internal elements are directed towards the corresponding photosensitive elements, following the inclined path, rather than horizontally. The conveyor system avoids damage in the flow of cigarettes when they are in contact with mechanical parts.
