Method and device for monitoring the puncture of tobacco processing machines

The invention relates to a method for monitoring the Function of tobacco processing machines. The invention also relates to an arrangement for monitoring the operation of tobacco processing machines. For reasons of rationalization, the tobacco processing industry is becoming more and more modern, i.e. faster and at the same time qualitative better product making machines used. Malfunctions, especially when they bring the machines to a standstill are of course special with machines of this type undesirable because of the associated loss of production can be considerable. On the other hand, it is inevitable that as a result of technology that is becoming more and more complicated more potential sources of error occur. It has been shown that especially with directly coupled machine units, so in so-called machine combinations, where one or several production machines for tobacco articles with tray filling machines or packing machines directly connected to one another are so that the flow of production goes straight away from one machine to the other, and with those-ddre "tendency to fully automatic control goes, so that-the bedtemitigspersonal Only supervisory functions are assigned, errors often occur again and again in the same module assembly. These Errors can significantly reduce the efficiency of the machines, without the management finding out the real reason, it could be that a message was issued by the operating personnel Negligence does not occur, be it that the reason is conscious is obscured because, for example, the operating staff operating errors committed.

The object of the invention is to provide a control facility for tobacco processors To create machines in which the operational

management is informed objectively and uninfluenced by the operating personnel about the puncture of the machines. The term "tobacco processing machines" is to be interpreted broadly. It can comprise machine units coupled to one another, such as rod machines producing tobacco articles using the rod process, filter attaching machines and tray filling machines or packing machines, but it can also comprise individually producing machines of the aforementioned types of machines. "Rod machine ¹¹ is understood to mean not only production machines which produce rod-shaped tobacco articles such as cigarettes, cigarillos or cigars, but also rod machines which produce filter rods. Further types of machines in which the invention can be used are tobacco cutters for producing cut tobacco and conveyor orders such as they are required, for example, to transport tobacco articles from a machine to a downstream machine.

The solution according to the invention is that the function of critical machine assemblies is automatically monitored and that malfunctions are counted and displayed. It is already known, downtimes in cigarette rod machines and register them with the actual production times and the theoretically possible production times to compare. Such counters do not provide any information about the type of malfunctions and the loss of production, caused by a disturbance of a species (DAS 1.195.655). It is also known the production result of a cigarette rod machine to monitor and indicate deviations from a certain standard by number and time (USA 3,259,746, 3,147,370). A breakdown of malfunctions is also possible with the last-mentioned known method not possible within the meaning of the invention.

It is desirable that the automatic failure analysis according to the invention be as complete as possible, i.e. as much as possible

provides a comprehensive picture of the malfunctions that have occurred. According to a further development of the invention, the punctures of several machine assemblies of a tobacco processing machine are automatically monitored and malfunctions are counted and displayed separately according to machine assemblies. In connection with the desire for comprehensive information of the management of the number of Punktΐοπϊ-disorders of a certain type are also interested in whether and how these disorders is ^j with respect to machine downtime have impacted; According to a further embodiment of the invention, the machine downtimes caused by the malfunctions are automatically added up and displayed. Another important statement about the importance of the downtimes for the production output is obtained when the sums of the machine downtimes are related to the total production time. "Production time" is understood to mean the time that has elapsed from a specific point in time during which the machine in question is used for the production of tobacco articles. A very meaningful production time in the present sense is the shift duration, which indicates the time that has elapsed from the beginning of a work shift.

You aforementioned arrangement, in particular to run of the method according to the invention is used, is characterized automatically through the function of critical machine assemblies monitoring probe elements, which are provided with displays Counters are connected.

Modern tobacco processing machines are highly complex and generally have a number of assemblies where malfunctions may occur that may lead to Machine standstill * Sometimes almost all machine stops triggered by just a single, poorly functioning assembly, the upstream and downstream Machines, i.e. a whole machine unit, for

Can bring to a standstill. So that such assemblies can be precisely determined without the involvement of the operating personnel, are according to a development of the invention in a tobacco processing machine with several machine assemblies Probe elements are provided, each of which is assigned to a machine assembly and connected to a counter is. This embodiment of the invention enables the management to remedy the situation after a relatively short time of the defective assembly, as it quickly covers the full extent of the productive

h onsverluste taught. The downtimes caused by a machine assembly are an essential aspect for assessing the significance of a malfunctioning machine assembly. According to a further embodiment of the invention, timing elements controlled by the probe elements are therefore provided for recording the idle times caused by the malfunctioning machine assemblies associated with the probe elements. These timing elements have summators for the recorded times. Another important piece of information about the significance of the downtimes for the production output is obtained from a quotient generator for the ratio of the sum of the downtimes and the total production time, the one with the

P is connected to the summator for the downtime and a timer for the production time.

A source of interference in tobacco-processing machines is a disturbed tobacco supply, which often indicates malfunctions in an upstream machine that delivers the tobacco. To detect such errors, a sensing element is provided for monitoring the supply of tobacco or auxiliary material to a tobacco processing machine. The term "tobacco" can be used, depending on the type of work, leaf tobacco including tobacco ribs (tobacco preparation plants, tobacco products), sonite tobacco or puffed tobacco (cigarette, cigar rod maeohine), filter

109840/0902

Stw .: Identifying and counting errors - Hauni file 1101 Bergedorf, March 11, 1970

tau (filter rod machine) and cigarettes (filter attachment machine, packing machine, tray filling machine). The term "auxiliary material" can include wrapping material (cigarette paper, tape tobacco, wrapping material for packs of tobacco articles, sealing tags), glue, paint, filter material, connecting material and the like. Conversely, however, the delivery of the articles manufactured on a tobacco processing machine can also be disturbed. In order to also be able to recognize such malfunctions, according to a further development of the invention, a sensing element is provided for monitoring the delivery of the tobacco articles processed on the tobacco processing machine. Tobacco articles in this sense are rod-shaped tobacco articles such as cigarettes, cigars and filter rods and cigarette blocks. A great number of malfunctions in tobacco-processing machines, through which the tobacco or auxiliary material usually passes in a constant flow of production, can be recognized according to a further embodiment of the invention by a sensing element for the production flow for tobacco and / or auxiliary material within the tobacco-processing machine . The production flow can be continuous or intermittent; the tobacco and the auxiliary material can have the form of an endless strip or strand or be designed as discrete pieces. in particular a production flow of discrete tobacco or auxiliary material parts on circulating conveyors such as drums, consists according to a further embodiment of the invention in a tactile element which is designed to detect the periodic absence of tobacco and / or auxiliary material in the production flow disruptions of production flow are detected AUOH, - the i 'ate lament nn the Produktionsiluß for errors exceeded

is designed to watch and a signal is emitted when a certain number of errors per unit of time is exceeded. 33a a certain one according to the calculation of probability In such a case, an exceeding number of errors in a row or in the unit of time does not occur there is a high probability that the module is malfunctioning. Tobacco processing machines have assemblies in which individual functionally important parts are exposed to damage through wear and tear or the use of force that act as disturbances. According to a further development of the invention, there is a sensing element for detection machine damage or wear and tear that cause malfunctions.

At least one probe element can be provided on a machine that produces tobacco articles or filter rods using the rod process be. At least one probe element can also be provided on a filter attachment machine. At least one probe element can be provided on a tray filling machine. At least one probe element can be attached to a transport arrangement for transferring tobacco articles from a machine to a other machine may be provided. At least one feeler element can be provided on a packaging machine that packs tobacco articles be. If two or more of the aforementioned machines are directly coupled to one another, that is, they are a machine unit represent, the counters and display arrangements assigned to the probe elements are advantageously combined accordingly. At least one probe element can also be provided on a tobacco cutter.

The invention is explained in more detail using exemplary embodiments with reference to the drawing. It shows:

FIG. 18 shows a probe element IU ₁ for monitoring a circular transfer movement of the transfer conveyor ÜF, especially its gondola receptacle 121, with which full or empty trays are transferred to or removed from the circular conveyor KP. If the crank arm 129 does not return to its desired position after executing a circular movement in which it is driven by the crank mechanism 128, this can cause damage to the circular conveyor KP and / or to the tray filling machine SP. A button 256, consisting of microswitch 257 and switching cam 258 on crank mechanism 128 sends a fault signal to line LH ¹ to switch off the drives of transfer conveyor UP if switching cam 258 does not actuate microswitch 257 after a transfer movement has been carried out.

This fault signal de-energizes the switched-on motor contactor 46 of the drive motor 39 of the cigarette rod machine ZM via the common line IH, so that the latter is stopped. At the same time, the fault signal applies to input a of the associated AND element from the series of AND elements UZ ₁ ... UZ ₄ , UF ₁ ... UF ₇ , US ₁ ... US ₃ , UU _{1 ... UÜp,} at the other input b there is still a signal from the common line IS, since the machine combination is still running at high speed in the first moment after the pushbutton has responded. The controlled AND element outputs a signal at its output c, which is sent to the downstream memory from the series of memories SZ ₁ ... SZ ^, SF ₁ ... SF ₇ , SS ₁ , SSgj SU ₁ and SÜp when the Input a sets. The output signal of the activated memory is retained even if the output signal of the upstream AND element has been omitted due to the path filling of the signal at its input b as a result of the signal on line IS due to the shutdown of the drive motor 39. The memory applies its output signal to the downstream counter from the series of counters ZZ ^ ... ZZ ₄ , ZF ₁ ... ZF ₇ , ZS ₁ , ZSp, ZU ₁ and ZU ₂ and increases the count by one unit. At the same time, the output signal is applied to the

If, after a while, a malfunction occurs again on the same machine assembly, it is triggered by the associated probe element emitted fault signal a further switching of the counter and a new activation of the timing element.

The results of the counters and the timing elements can be transmitted by a transmission signal on line LÜ to the assigned display device from the series of display devices AZ ₁ ... AZ., AF ₁ AF ~, AS ₁ , AS ₂ , AU ₁ and AU ₂ . The operation of the monitoring arrangement will be described again in detail using a machine assembly of the filter attachment machine FA, which is used to roll the groups each consisting of cigarette-filter plug-cigarette for the purpose of connecting a group with a connecting sheet. The corresponding machine assembly is monitored, among other things, by the probe element IP. If, for whatever reason, a group does not get into the rolling channel 201 between the rolling drum 72 and the rolling block 73, this malfunction will result in a jam in the production flow of the group. The following groups accumulate and push the feeler lever 198 up so that its arm 202 actuates the microswitch 203 to emit a fault signal. This fault signal arrives via line LH to the motor contactor 46 of the drive motor 39 of the cigarette rod machine ZM and de-energizes it, so that the drive motor 39 is switched off and the

The fault signal is set via AND element UF, - the memory SS ¹ , - whose output signal - the counter reading of the counter ZF ₁ - increases by one unit and activates the timer TF, -. The operator, who is alerted by the shutdown of the machine, if necessary by a _{warning device assigned to the probe element IP 1} , eliminates the error, in the example the jam, after which he presses the button 42 to switch on the drive motor in slow gear. After the machine has started, the operator presses the button 43 to switch on the overdrive, whereupon a signal reaches the clear input b of the memory SF ^ via line XS, the output signal of which disappears so that the timer TPj- stops.

When the following error occurs in the roll area, which again leads to a "jam" and thus to the shutdown of the machine combination, the counter reading of the counter ZF ₁ - is again increased by one unit and the timer TPe is reactivated until the overdrive has been eliminated is switched on and the machine is running properly again After a transmission signal has been sent via line LÜ, the counter reading of counter ZF, - and the accumulated (.sumed) times on the timer TF, - are transmitted to the display device APc.

When a malfunction _{signal is emitted by the pushbutton elements IU 1} or IÜp, only a switch-off signal for the drives of the transfer conveyor is initially emitted on line LH ^1. In addition, it is determined by probe element IS ₃ whether 'the puncture fault of the monitored machine assembly of the transmission conveyor has stopped so long that the.

In the second packaging web, an identically designed pushbutton element is provided, which therefore no longer needs to be described. The tactile element has a number of tactile levers 328 corresponding to the number of cigarettes in a layer of the cigarette block, which are resiliently pressed against the cigarettes in the upper layer of a cigarette block 327 and drag on them. If a cigarette is missing in a tested cigarette block, the associated touch lever 328 rotates about its axis 329 'so that its arm 331 actuates an associated microswitch 332 to emit a malfunction signal, which is routed via an AND element 333, whose input a is applied to it XH and the input a of the AND element UP ₅₀ IS ⁸¹³¹³ S ** A clock generator 334 with a clock disk 336, which is provided with pulse cams 336a, and with an initiator 337, which is connected to input b of the UHD element 333, is used for the timing of the delivery of the fault signal, which may only be passed on when a cigarette block 327 is in the correct position with respect to the feeler element.

Microswitch 346 for outputting a malfunction signal via AND element 347, whose input a the malfunction signal is fed to, can be operated to a counting input a of a counter 348. The counter 348 is designed in such a way that it does not emit the actual _{fault signal arriving on line LH and the input a of the AND element UP ^ 02} until a preset number has been reached. If a signal arrives at a reset input b of the counter 348, the counter reading is reset to its initial value (eg zero). Such a reset signal is always from

h delivered to an AND gate 349 when the feeler lever 342 has detected an outside wrap around the cigarette block and a corresponding signal on input a of the AND gate 347 is omitted. A clock generator 351 with a clock disk 352 (pulse cam 352a) and an initiator acted upon input b of the AND element 347 and input b of the AND element 349, whose input a is acted upon by the output signal from microswitch 346 negated by a negation element 354. The clock generator 351 is used to control the correct measuring time, in which a pack moving past the feeler lever 342 has the correct measuring position and to output reset pulses to input b of the

Drawn in full line in a position where it begins to impact. During the impact it is pivoted in the direction of arrow 369a, its tip 361a, which is guided in a slot (not visible) in chamber 359, pushes the almost completely folded pack 360 out of chamber 359 into the position marked with 36Oa below the Stacking tower 313 (the end position of the packer 361 is shown in dash-dotted lines), in which the pack is pushed by the ram 368 in order to carry out the last EaItvorganges. The chamber 359 is then moved back, and the packer rake pivots back in the direction of arrow 369b in its position shown in solid lines. In this way, pack after pack is folded. If a pack 360 has not been pushed all the way into the receptacle of the chamber 359 as a result of a puncture fault in the packing machine, i.e. if it still protrudes from the rear, then the pack head can be squeezed by the packer tip 361a so that it is no longer pushed out of the chamber and into kaiin reach their position 360a. In such a case, there is the risk that the lifting ram 368 pushes the squeezed pack 360 against the right boundary wall 313a and / or the upper chamber wall 359a, which can damage the paekmasohine, or at least the following pack no longer fits into the receptacle Chamber 359 can be taken over. If a pack is improperly transferred into its position 360a, for example as a result of the pack being damaged by the packer 361 as described above, the latter remains somewhat behind the control disk 366, so that its roller 363 comes free from the control disk.

Display devices correspond to the structure and mode of operation with the same reference numerals, at least 300, marked machine parts of Figures 1 to 4 and 7 to 14.

The pushbutton element H ₃ Q ₁ ^{on the} cLer packaging machine PM works as follows:

If the supply of cigarettes to be processed on the packing machine via the delivery belt 82 is disturbed, ie one or more cigarettes are missing in a cigarette block 327, which suggests faults in the shafts of the magazine 301, then one or more feeler levers 328 pivot about their axes 329 , so that their arms 331 operate associated microswitches 232 to emit fault signals. The clock generator 334 ensures that fault signals are only transmitted during certain times within a working cycle, specifically when a cigarette block 327 is in the area of the sensing lever 328, while in the times when there are gaps between successive cigarette blocks in the area of the sensing lever the output of error pulses is suppressed. The fault signal reaches the motor contactors of the drive motors of the cigarette rod machine ZM and the packing machine PM via line LH and de-energizes them so that the drive motors are switched off and the machine combination comes to a standstill. ^{The fault signal sets the} memory SP ₃₀₁ via AND element UP ₃₀₁ , the output signal of which increases the count of the counter ZP ₃₀₁ by one unit and activates _{the timer TP 301.} The operator who is responsible for shutting down the machine

After the machine has started, the operator presses the button to switch on the overdrive, whereupon a signal arrives via line IiS to the input b of the memory SPa ₀ -), the output signal of which disappears, so that the timer TP ₃₀₁ stops. If the following error occurs, which leads to a faulty block, the count of the counter ZP _{301 is} again increased by one unit and the timer IP ₃₀₁ is activated again until the overdrive is switched on after the error has been eliminated and the machines are running properly again.

After delivering a transmission signal via line IIU the count of counter ₃₀₁ ZP and the accumulated (summed times) on the timer TP ₃₀₁ are transmitted to the display device AP _{three hundred and first}

The IB ₅₀ O ^{probe element on the} PM packing machine works as follows:

If the feeler lever 342 is set by the timer 351 Measurement period no external wrapping about the cigarette block 327, it pivots about its axis 343 so that his arm 344 actuates the microswitch to output a signal which, via AND gate 347, the counting input a of the counter 348 applied. If the outer wrapping blank 341 is missing again on the following cigarette block 327, the feeler lever 342 releases a further output signal in the manner described on microswitch 346, which again counts input a of the counter 348 is applied. If the number of false signals emitted one after the other by microswitch 346 corresponds to Presetting the counter 348, then the counter 348 indicates

If the feeler lever 342 detects an outer wrap blank on a cigarette block 327, there is no false signal at the microswitch 346, with the result that a pulse from the clock generator 351 reaches the reset input b of the counter 348 via the AND gate 349

W can, which is thus reset to its initial value. The totaled results of the counter ZP ₅₀₂ and the time measuring element TP ^ ₀₂ can be transmitted again to a transmission signal via line Ιίί to the display device AP ₅₀₂ .

The probe element IP ₅₀₅ on the PM packing machine works as follows:

If a pack is inserted into the receptacle of the chamber 359 in such a way that its head 357 protrudes from the receptacle so that the rake 361 squeezes the protruding part with its tip 361a and the folding process is not carried out correctly nor the pack properly from the packer 361 in their

fc position 36Oa can be pushed, but gets stuck on its way in the receptacle 359, then the roller 363 detaches from the control disk 366 and the microscope holder 367 can emit a fault signal that stops the machine combination via line IH and the counter reading _{via memory SP 505} of the counter ZP _{505 is} increased by one unit and the timer TP _{505 is} activated. If the operator has removed the defective package from the receptacle 359, which, if the machine had not been shut down, would have led to a jam of the following packages and thus to a complete collapse of the production of the packaging machine PM, then after pressing the button for the Overdrive

FIG. 25 shows a tobacco cutter of the KT type from Hauni-Werke, known in the cigarette industry, which is briefly described below. For conveying, cake-forming and pressing, the sheet material 401 fed in from a supply queue is fed in a shaft 402 from a kitchen 405 cyclically in continuous succession to a pressing device 407 consisting of two press chains 404, 406. The press chains, which converge towards one another in the conveying direction (arrow) and can be driven by an electric drive motor 408, grasp the sheet material and convey it to a cake 409 with an upper part 411 and lower part, while pressing and compressing it. A pressure generator 414 acts on the press chain 404. The lower part 412 forms the counter knife for knives 416 in a knife drum 418 rotatable by an electric drive motor 417, so that the knives cut narrow strips of tobacco fibers from tobacco cake 409 as they rotate. The tobacco fibers 419 are then conveyed away. A grinding wheel 421, which is dressed by a diamond 422, is used to grind the knives 416. The tobacco cutter KT has a number of probe elements IK ₁ , IK ₂ and IK ₃ , each of which is assigned to a specific assembly and emits a signal in the event of malfunctions. These signals are fed via a common line to motor caps 423 and 424 of the electric drive motors 408 and 417, respectively, which are de-excited by the fault signals and switch off the drive motors. The disturbance signals also apply to the inputs, a maintained AND elements UK ₁ or UK ₂ or UK ₃ , whose inputs b apply signals via a common line LS

that are released when the tobacco cutter drive is switched on. The outputs c of the aforementioned AND elements are each connected to set inputs a associated memory SK ₁ or SKp or SK, their clear inputs with line LS and their outputs c with the inputs of counters ZK ₁ or ZKp or ZK, as well with timing elements TK ₁ or TKp or TK are connected. Triggered by a signal via the transmission line LÜ, the results of the counters and timing elements can be transmitted to writing display devices AK ₁ or AK ₂ or AK ^. The counters ZK ₁ ... ZK * are so

* formed that they are exposed to a signal of

the memory SK ₁ ... SK to advance by one unit. The Zeitmeßelemente TK ... TK ₁ are formed so that they are the times during which the memory proposed SK ₁ ... SK, output signals at their outputs c, so set, measure, wherein the measurement values are summed at the same time. When a transmission signal is output on the transmission line LÜ for the transmission of the measured values of a timing element to a display device arranged downstream of it, the entire time is transmitted during which the output signals were present at the output of the memory connected upstream of this display device.
The tobacco cutter KT has a number of probe elements IK ₁ ,

P IKp and IK, on, each of which is a particular one

Module is assigned and emits a signal in the event of malfunctions.

The probe element IK ₁ for monitoring the tobacco supply to the tobacco cutter is assigned to the area of the mouthpiece 413 and is designed as an electromechanical limit switch 426, which is actuated by the upper part 411 of the mouthpiece 413 to emit a fault signal via a switching rod 430 when the mouthpiece height is at Lack of tobacco becomes too low.

The probe element IK _? is also assigned to the area of the mouthpiece 413 and is used to monitor the tobacco cutter for damage to a machine element in this area, namely a knife 416 in the knife drum 418 The lower part 412 of the mouthpiece 413, which forms the rain gauge for the knives 416 of the knife drum 418, is attached. If a foreign body is in the tobacco, for example a piece of metal, this can damage the tobacco cutter Thin shear pins attached to the machine frame, which shear off as soon as the pressure of a knife 416 of the knife drum 418 becomes too great in the event of a malfunction described above the shear pins down and actuates the M by means of a chain 428 and a switching rod 429 micro switch 427 for emitting a fault signal.

To describe the Tästelementes IK ,, which is assigned to the knife drum, and which is used to monitor the Wear of the knife 416 of the knife drum 418 is used, Figure 26 is used, in which a feed device for a knife 416 is shown on an enlarged scale. The J Knife 416 is held between two plates 431 and 432 and is movable by a worm gear 433 lower plate 432 movable in the direction of arrow 434. With the plate 431, a switching pin 436 is connected, the one can operate microswitch 437 arranged at the end of the path of the cutter insert. In the microswitch circuit lies a battery 438 as well as one at the side end of the Actuating magnet 440 arranged on the drum for a switching cam 439 (visible in FIG. 25) for actuating an associated fixed switch 441 (FIG. 25). At maximum knife wear, switch pin 436 activates the micro

switch 437, so that the actuating magnet 440 moves the switching cam 439 into its switching position. When passing by of the switching cam 439 on the stationary switch 441, the latter emits a fault signal.

Operation of the monitoring arrangement of FIGS. 25 and 26: If one of the switches 426, 427 or 441 of the probe elements IK ₁ or IK ₂ or IK ^ gives a fault signal because the tobacco supply is disturbed, the lower part 412 of the mouthpiece 413 has been sheared off or the knife 416 T are used, this signal is sent to the motor contactors via the LH line

ψ 423 and 424 of drives 408 and 417, which are switched off. At the same time, the signal is applied to the input a of the assigned XINI) -Gl ie of the UK .. or UK ₂ or UKj, at whose input b there is still a signal at the first moment because the drives are still switched on. By applying the set input a of the downstream memory SK ₁ or SKg or SK, this is set, which increases the counter reading of the subsequent counter ZK ₁ or ZK ₂ or ZK ₅ by its output signal at output c and the connected Timing elements TK ₁ or Tk ₂ or TK ₅ activated. Has the operator eliminated the error; and the drives 408 and 417 switched on again, then via line

* LS a clear signal on input b of the set memory, the output signal of which disappears, so that the activated time measuring element is put out of action again. In this way it can be read from the counters and the accumulated times of the time measuring elements, which are transmitted by a transmission signal on line LÜ to the writing display devices AK ₁ or AK ₂ or AK, how often a certain error has occurred on the tobacco cutter and how much downtime it caused.

The invention is not restricted to the machines shown. For example, other strand machines can be used according to the principle of the invention with individual critical assemblies

assigned feeler elements for detecting malfunctions be provided, which turn off the machine with their fault signals on the one hand, and on the other hand the fault statuses of Increase error counters and timing elements for recording activate the downtimes caused by the errors. The results can be transferred back to writing display devices. Such strand welding machines can Be cigar rod machines or pilter rod machines. Similarly, other transfer conveyors such as magazine fillers or pneumatic transport systems can be used for Tobacco items, e.g. for cigarettes, cigars or filter rods, assigned to tactile elements for monitoring critical assemblies be the counter and timing elements with their fault signals apply.

Another possible application is cigars processing or packaging machines such as winding machines or cigar end shapers. Furthermore, the invention can be used in other wrapping machines for Tobacco-processing articles such as cell glass wrapping machines and container packaging machines are used. Finally, the use of the invention is also possible in so-called tobacco preparation plants, in which the tobacco is prepared and in the process entripping, conditioning | and is subjected to aging processes.

The advantage of the invention is that the management on the counter readings and the measurements of the timing elements as well as the logs of the writing display devices, the reasons for a possible drop in Efficiency of tobacco processing machines can be seen. As the machine assemblies according to the number of occurrences on them Faults and the resulting loss of time can be monitored quickly and effectively and productivity through a readjustment of the
