printing cylinder

45,46 has advantageously carried out pre-assembled and pre-adjustment, just in opposite mode it is pushed to afterwards, wherein printing cylinder the axle with motor shaft clutch position place form closure couple together.

The material bands 21 (cigarette paper band) that successively moves in well-known machine is printed by one or more synchronously driven printing cylinders.This means, when the transform size specification, wherein changed the length of cigarette, that just must change printing equipment.Can carry out adaptive by the following method to the length of the section of sending to press according to the innovative a kind of special design of the present invention: changing at two must be the rotating speed of the printing equipment between the printing process of synchronous operation.If the printing between two synchronous operation is rolled and is driven quickly, the segment length has just shortened so, and vice versa.Following example ground illustrates the approach that realizes this method according to the control device of motor 48: host computer control device 200 provides first kind of cadence signal with the continuation synchronized movement of paper tape 21 for control device 201.This signal for example can have a clock pulse in every millimeter band continuous motion, and only has frequency change slowly, and this is because the inertia of the main drive system of it and machine is bound up.Control device sends second kind of cadence signal to the motor 48 that is designed to stepper motor, and this motor just rotates a step when each clock pulse of second kind of signal.Motor for example can change a whole circle when per 1000 clock pulses.Control device 201 has a frequency multiplier of itself knowing 204, and it exports the third cadence signal that is synchronized with first kind of cadence signal, for example is thousand frequencys multiplication.If but same known counter has recorded the clock pulse of the predetermined quantity that is called the factor of the third cadence signal, that just flows to a counter 203 with this third cadence signal.

The circumference of printing cylinder 45 is 130mm in a simple case, and will print out image with this printing equipment 23 spacing with 130mm on material paper tape 21.The clock pulse that this host computer control device 200 just sends 130 first kind of cadence signals during about paper tape transportation 130mm to control device 201, frequency multiplier 204 produces the clock pulse of 130000 the third cadence signals thus.Be predefined for 130 for counter 203 as the factor, thereby it just send 1000 clock pulses of second kind of cadence signal to motor and makes this motor change a whole circle when the third cadence signal is 130000 clock pulses.Always keeping synchronous this moment between printing cylinder 45 and paper slip band 21.

In the another one example, to printed image be printed on the paper slip band 21 with the spacing that is shorter than 130mm by printing equipment 23.Stored a kind of characteristic curve 300 of number 202 li of memories, as shown in Figure 4 for this reason.On axis 301, mark the position of memory point, marking the value that has the factor in this memory point on the axis 302.Along with each clock pulse of first kind of cadence signal is just read the next one value of the factor and it is passed to counter 203 at memory.The value of distributor is corresponding to value 303 when protuberance 98 on printing cylinder 45 and the effect of paper slip band, and synchronous operation for example is 130.When protuberance 98 just transfers to counter 203 with the lower value of the factor from paper slip band 21 leaves after, the result makes the frequency of second kind of cadence signal, thereby also just makes the rotating speed raising of motor 48 and printing cylinder 45.This moment, factor values reduced with a kind of mild inclined-plane, so that make motor only bear a little moment of accelerating.After motor 48 roughly changes half-turn, improve factor values again at leisure, synchronously reach value 303 again again with before the effect of paper slip band at protuberance 98 until it.

(line 304) motor 48 sends a signal and gives memory 202 after having changeed a circle, and goes up first memory and light and read this factor values.

For the typographic(al) mark of spacing distance greater than 130mm is printed onto on the paper slip band 21, stored the another kind of characteristic curve 310 of factor values 202 li of this memories, it has factor values higher when synchronous beyond paper slip band 21 is gone in protuberance 98 effects.Fig. 5 has represented a kind of like this characteristic curve.The part of Fig. 5 has improved 10 corresponding to part and the label of Fig. 4.Each printing cylinder can be provided with a control device with memory 202 in a kind of printing equipment with a plurality of printing cylinders.

Parts 200 to 204 among Fig. 2 are functional parts and can realize in software a kind of automaton or the control computer.
