With reference to Fig. 1, in present embodiment, intaglio press also includes detection means 100 and frequency converter 200.Detection means
100 electrically connect with frequency converter 200.Detection means 100 can be in intaglio press spool for each revolution after to frequency converter
200 output note ring signals.Wherein, remember that ring signal can make frequency converter 200 recognize spool and have rotated a circle.Specifically, note circle
Signal can be the signal that the frequency converters 200 such as electric signal can be recognized.Spool is Scroll or unreeling shaft.
Frequency converter 200 calculates the week of current spool cross-sectional profiles line according to the newest two neighboring note ring signal for receiving
It is long, and current spool coil diameter is calculated according to the girth.Wherein, spool cross section refers to by spool and is wrapped on spool
The integrally-built cross section that paper roll is constituted.Spool coil diameter refers to the overall knot being made up of spool and the paper roll being wrapped on spool
The cross-sectional diameter of structure.
Wherein, if frequency converter 200 continuously receives two note ring signals, represent spool and just have rotated a circle.Paper roll is
Finger is wrapped in material on spool, and the structure that is collectively formed with spool of paper roll is shaped as cylinder, therefore spool cross section
Contour line be circle, and the circular diameter is exactly spool coil diameter.In addition, after spool have rotated a circle, material is also moved
Moved with above-mentioned girth identical length, as long as therefore calculate the length that material is moved in this circle, then equivalent to drawing
The girth of current spool cross-sectional profiles line, and then can (wherein, L is spool cross section wheel using formula L=∏ × D
The girth of profile, Π is that constant 3.14, D is spool coil diameter) draw current spool coil diameter.
After intaglio press brings into operation, after frequency converter 200 often receives two note ring signals, i.e., spool have rotated one
After circle, frequency converter 200 can just calculate current spool coil diameter, and because the coil diameter of spool is sent out after spool rotation is turned around
Changing, therefore embodiment of the present invention is capable of the situation of change of real-time detection spool coil diameter.
So, if spool is unreeling shaft, detection means 100 is arranged on and unreels part such that it is able to detect unreeling shaft
Rotational case.After detection means 100 detects unreeling shaft rotation to turn around, note ring signal, this time-varying are sent to frequency converter 200
Frequency device 200 can recognize unreeling shaft and have rotated a circle, and then calculate the girth of current unreeling shaft cross-sectional profiles line, most
The current coil diameter that unreels is calculated afterwards (also referred to as unreels diameter, i.e., the knot being made up of with the paper roll being wrapped on unreeling shaft unreeling shaft
The cross-sectional diameter of structure).
If spool is Scroll, detection means 100 is arranged on winding part such that it is able to detect the rotation of Scroll
Situation, after detection means 100 detects Scroll rotation to turn around, sends note ring signal, at this moment frequency converter to frequency converter 200
200 can recognize Scroll have rotated a circle, and then calculate the girth of current Scroll cross-sectional profiles line, finally count
Calculate current winding coil diameter (also referred to as take-up diameter, i.e., the structure being made up of with the paper roll being wrapped on Scroll Scroll
Cross-sectional diameter).
In addition, the working method of detection means 100 can be following two situations：
The first situation is：Spool of the detection means 100 only in intaglio press for each revolution after to frequency converter 200
Output note ring signal, and any signal is not produced during spool has not rotated a circle, as long as at this moment frequency converter 200 connects
The signal for receiving the transmission of detection means 100 can determine whether that spool have rotated a circle.
Second situation be：Detection means 100 to the output signal of frequency converter 200, but can all not rotate in spool all the time
The signal of the output of detection means 100 during a complete circle, the signal of the output of detection means 100 when a circle has just been rotated with spool
(remembering ring signal), the type or value of both signals is different, so that frequency converter 200 can identify note ring signal.
In sum, the girth of current spool cross-sectional profiles line is calculated automatically, and current spool volume is drawn according to the girth
Footpath, the parameter such as initial coil diameter, material thickness without receiving user input, simplifies operating process, reduces cost.In addition,
As long as can just calculate current spool coil diameter after receiving two note ring signals, system response time is improve.
Wherein in one embodiment, Fig. 2 is refer to, detection means 100 includes the first detection unit 110 and the second detection
Unit 120.First detection unit 110 is installed on spool.Second detection unit 120 is installed in intaglio press for placing
On the fixed structure of spool.Therefore, the first detection unit 110 follows spool and rotates, and the second detection unit 120 be to maintain it is quiet
Only.Also, the second detection unit 120 is electrically connected with frequency converter 200.
In spool rotary course, whenever the rotation of the first detection unit 110 to the second detection unit 120 at a distance of setting away from
From position when, the second detection unit 120 then to frequency converter 200 send note ring signal.In other words, whenever the first detection unit
When 110 rotations are to the second detection unit 120 at a distance of the position of setpoint distance, the second detection unit 120 can perceive the first inspection
The close of unit 110 is surveyed, and then it is note ring signal (for example, electric signal) to produce trigger signal, therefore, if the second detection is single
Unit 120 is double to produce note ring signal, then represent spool and drive the first detection unit 110 to have rotated a circle.
Specifically, detection means 100 can utilize the sensing principle of approach switch sensor to realize.At this moment, the second detection
Unit 120 can be approach switch sensor, and the first detection unit 110 can be close for that can be approached switch sensor perception
Detected element (for example：If approach switch sensor is inductance type transducer, detected element can be then metal unit
Part).
It is understood that the specific implementation of detection means 100 is not limited to above-mentioned situation, as long as can be in intaglio plate
Ring signal is remembered in the output of backward frequency converter 200 to spool in printing machine for each revolution, and such as detection means 100 can also pacify
Mounted in the motor side for driving spool rotation, and turned around after (at this moment spool accordingly have rotated a circle) motor shaft rotation is detected
Note ring signal is sent to frequency converter 200.
Wherein in one embodiment, frequency converter 200 is according to the current spool of the newest two neighboring note ring signal for receiving
The mode of the girth of cross-sectional profiles line is specially：Frequency converter 200 receive one note ring signal after, every setting time section
(any point i.e. on material is in nearest setting time section to calculate the mobile length in the setting time section of firm experience of material
Common mobile arc length), and after next note ring signal is received, will be between moment be arrived between the two note ring signals
Time period in all length that obtains add up, the total length mobile altogether in this circle to draw material, equivalent to drawing
The girth of current spool cross-sectional profiles line.Wherein, the length of material movement is moved equivalent to any fixing point on material
Arc length.
As an example it is assumed that spool total time for turning around of rotation is T second, setting time section is S seconds, then from receiving one
Individual note ring signal starts, and by first after S second, then calculates the length moved in first S second interior material, passes through again afterwards
Second after S seconds, then the length moved altogether in second material in S seconds is calculated, the like, (received after eventually passing through T seconds
To after next note ring signal), T/S length has been obtained, this T/S length is added up, you can obtain material and revolved in spool
Turn common mobile length during this circle.
Specifically, the specific implementation of the length of the calculating of frequency converter 200 material movement can be：Frequency converter 200 is specific
Setting time section of the material in firm experience can be calculated every setting time section according to formula Li=(LsCur+LsBef) × T/2
The length of interior movement.Wherein, LsCur be the firm experience setting time section at the end of material movement linear velocity.LsBef is should
The linear velocity of material movement when just the setting time section of experience starts.T is the corresponding duration of setting time section.Also, the value of T
Smaller, no matter the state of change of line speed is to accelerate, slowing down or constant speed process, the deviation of the Li for calculating is smaller.
Wherein, linear velocity can using it is various it is traditional by the way of obtain, if encoder is installed on such as carry-over pinch rolls, and
Encoder then sends a pulse after carry-over pinch rolls rotation is turned around, then frequency converter 200 then can be common in 1 second according to encoder
The umber of pulse of feedback and the circumference calculating of carry-over pinch rolls cross section contour go out current linear velocity.
Specifically, frequency converter 200 can determine that calculating material every time moves using the time of timer generation interrupt signal
The time of dynamic length, at this moment above-mentioned setting time section refers to just the two neighboring time interval interrupted and occur between the moment.So,
The specific formula for calculation of the length moved for above-mentioned material, i.e. for Li=(LsCur+LsBef) × T/2, LsCur is then to work as
Linear velocity when preceding interrupt signal is produced.Linear velocity when LsBef is then produced for a upper interrupt signal.
So, during spool rotation is turned around, timer can regularly send multiple interrupt signals.Also, frequency converter
The length Li of material movement in the 200 real-time time intervals calculated between each two interrupt signal.Finally, when spool rotation is turned around
Afterwards, spool has just been revolved during turning around calculate all material movement length (i.e. L1, L2 ... Ln, wherein, Ln for volume
The length that axle is just obtained for the last time during rotation is turned around) it is cumulative, obtain material and just rotated in lap time in spool
Common mobile length, so as to obtain the girth of current spool cross-sectional profiles line.Also, due in timer, Ke Yishe
The time interval (i.e. T) between two neighboring interruption is put for less value, and T values are smaller, the computational accuracy on above-mentioned girth
It is higher, therefore the accuracy for calculating coil diameter can be improved using the mode that timer generation is interrupted.
Wherein in one embodiment, Fig. 2 is refer to, frequency converter 200 can include peripheral hardware control module 210, protection mould
Block 220, unreel in module 230, winding module 240 these modules one or more.Next each mould will specifically be introduced

Dynamic device etc..Also, when switching signal is enabling signal, frequency converter 200 then starts corresponding equipment；When switching signal is pass
When closing signal, frequency converter 200 then closes corresponding equipment.For example：When light switch sends enabling signal, frequency converter 200 is then
Start lighting device, otherwise close lighting device.When pressure roller switch sends enabling signal, frequency converter 200 then starts pressure roller, no
Then close pressure roller.When heater switch sends enabling signal, frequency converter 200 then starts heater, otherwise closes heater.
When scraper starter sends enabling signal (at this moment, current linear velocity starts linear velocity more than scraper), frequency converter 200 is then opened
Dynamic scraper, otherwise closes scraper.
Specifically, frequency converter 200 is additionally operable to take safeguard measure to intaglio press in the case of setting, so as to improve recessed
