METHOD AND MEANS FOR THE IDENTIFICATION OF A ROLL
The invention relates to a method, and to an arrangement for the application of ~he method, for the identification of rolls, in particular, big paper rolls, by means of a code attached to or marked on the end surface of the roll, S which code comprises several code characaters located side by side.
Big paper rolls are produced in a paper mill for different deliveries comprising rolls of different axial length, di~erent diameter and/or different weight. ~olls being .lO similar with respect to the properties just mentioned may comprise different paper grades having different density and/or composition. Also the package requirement may vary, Eor in~tance, shipping of rolls to overseas cus tomcrs requires a much mor~ durable package than rolls delivered to nearby customers. In order to avoid delivery delays it is also important to be able to reproduce a roll of a speciic character quickly, if the original roll winding has failed or if the roll has been damaged.
In an automatized paper roll production and packaging line, for instance/ the roll weight and diameter are measured and the measured values are transferred to the governing and data processing unit of the lineO
A labelling unit ~.oduces an identification label for each roll and attaches it to the end surface of the roll.
~` ~
The label indicates the measured values and possibl~ also other recorded data identifying the customer and the paper grade of the roll. All data are expressed in the form of a code modified to suit an automatic reader device.
It is suitable to use a so-called bar code formed by a series of s~ripes. The code is read across the stripes by sensing the value of the code stripes one after another~
In order to facilitate the code reading~ ~he label is usually attached to the center of the roll. Nevertheless, there will be variations in the vertical position of the label/ because the roll diameters may vary considerably~
Another problem is that the scanning plane of the reader has no connection with the random orientation of the label.
It is known to eliminate this problem by rotating the roll during code reading by means of scanning all over the roll end surace by means of a narrow~ collimated optical beam.
Thus, the scanning motion of the beam has to cover the entire end surEace of the roll~ This is cumbersome, time-consuming and uneconomical. Moreover, roll rotation requires rotation means, which increases the expenses.
Rotation of a roll weighing seeral tons is slow, and slows down the entire roll handliny process.
The object of the invention is to provide a roll identifi-cation method suitable for an automati2ed roll handling . ~
. .~ ,.~. , line and means Eor the application of the method, by means of which roll identification can be made rapidly, accurately and economically.
According to one aspect of th~ invention there ..s pro-vided a method for identification of rolls, in particular stationary big paper rolls, by means of a fixed ~ode attached to or mar ked on ~h~ end surface of the roll, which code comprises several characters located side by side and including the first and last character thereof~
said method including the steps of reading said code by means of a movable, combined optical bec~m transmitter-receiver devi~e, scanning by a single narrow beam, a restricted angle in a plane at a scan angular speed, adjusting said scanning to a central position relative to said roll surface, adjusting said scanning to extend slightly over the end limits of said code at its both ends, and turning at a rotational speed said scanning plane until .at least one observed sweep over the entire code is obtained by the rec~ption of a signal including said first and last character.
According to another aspect of the invention there is provided An arrangement for identification of code-marked rolls, in particular, stationary big paper rolls, said arrangement comprising means for measuring a roll, a movable comblned narrow beam transmitter-receiYer device for scanning and reading at the same time an entire code applied to the end surface of said roll, said code comprising a plurality of fixed characters located side by side, said arrangement further cDmprising means for turning the scanning plane of said beam, and means for moving said transmitter-receiver vertically and for governing the vertical movements of the transmitter-receiver in proportion to the roll diameter to keep said transmitter-receiver positioned at or close to the longitudinal axis o said roll.
The roll code zan easily be read by using a combined optical beam transmitter-receiver known per se, prefer-ably a ].aser device, which scans over a restricted angle in a plane. By means of the linear motion of the optical beam, a good alignment of the beam at the label code is obtainable. All the elements of the code are read by arranging the scanning to extend slightly over the code area at both its ends~ The time spent in scanning is used economically, since mainly only the area including infor-mation is scanned. By turning the scanning plane t 50 that it crosses the total code, all elements of the code can easily ~e read.
In a preferred embodiment of the invention, the center of the scanning angle is adjusted to fall between the first , ~
and last characters of the codeO Then the scanning plane will all the time sweep the code, at least partly. By adj usting the magnitude of the scanning angle so that it corresponds to about twice the width of the code r the scanning will with certainty extend all over the code without being unnecessarily wide.
In order to adjust the scanning of a label centrally attached to a roll end, the transmitter-receiver is moved in a vertical direction according to the measured value of the roll diameter, until the midpoint of the scanning is close to ~he roll axis. ~ favourable way to carry out this positioning is to combine, in any manner known per se, the vertical movements of the transmitter-receiver and the roll diameter measuring device so that the transmitter-receiver movement is about half the movement o the measuring device. The roll diameter measuring device may al50 comprise ccrrection means taking into account the influence on the roll center position caused by the horizontal distance between the roll supporting members. In an automatized roll handling plant, the correction can be taken into account by computing and be transmitted to the operational center of the arrangement for exact posltioning of the transmitter-receiver.
By turning the scanning plane at an angular speed consider-ably lower than the angular speed of the scanning, the code ~5~
reading precision will be unaffected by the scanning plane rotation~ The ratio between the scanning angular speed and the rotation speed of the scannlng plane should prefer-ably exceed 10:1u This will ensure that several scannings include the total code. The scanning can be terminated after the receiver has received a signal group including the first character as well as the last character of th~
code. This indicates that necessary information has been received. There might be several readings to confirm the information, By continuously turning the scanning plane at the most through 180, a momentary orientation of the plane rela-tive to the code ~ill be such, that all the characters of the code are scanned at least once.
The invention also relates to an arrangement for the application of the described method.
The invention will now be described, by way of example, with reference to the accompanying drawing, in which - Figure l schematically shows a perspective view of one embodiment of the inventionf and - Figure 2 shows a detail of Figure l.
In the drawing, reference numeral l refers to a big paper roll, at the end 2 of which an identification label 3 is ., attached. Label 3 includes for roll identification a bar code 4 formed by parallel stripes 5. For identifying the fore and tail end of the code, it comprises a first stripe 5a and a last stripe 5b of special character. For reading code 4, there is an optical transmitter-receiver 6, ~or instance, a laser device transitting a n~rrow, collimated beam 7. Beam 7 scans rapidly over a restricted scanning angle a in a plane 8. The contact point 9 of beam 7 on roll 1 moves along a line 10 at the roll end surface 2.
Transmitter-receiver 6 is rotatably supported on a carrier 16, so that scanning plane 8 can be turned around an axis 11 lying in said plane. The angular speed of the scanning beam movement continuously to and fro is considerably higher than the turning speed of plane 8 around axis 11~
A device 13 or measuring roll di~meter is schematically illustrated, as well as means 15 for vertical movement 15a of device 13~ The diameter measuring device may, for instance, be a mechanical slide gauge, the rigid jaw of which is the pair o roll supporting drums 12. The distance between the rigid jaw and the movable jaw setting on~.o the top of the roll mantle is registered electrically and the measured value is transferred to a computer unit governing the process. Transmitter-receiver 6 is adjusted in a vertical direction according to the diameter data of roll 1, so that the center lOa of the scanning angle will come close to the lon~itudinal axis of the roll 1. For vertical movement of measuring device 13 and transmitter-receiver 6 there are displacement means 15 and L4, for instance, chain or bel~ drives. They can be intercon-nected, so that movement 14a is about one half of movement 15a~ The interconnection members are not shown in the drawing. Conventional means can be used for ~his purpose.
As a result of the turning of scanning plane 8, scanning line 10 turns around a point lOa, as shown by arrows 18 in Figure 2. Since the to and fro scanning speed of beam 7 is considerably higher than the turning speed of plane 8, several readings of the code are made. Thereby, at least one reading ;s carried out so, that code 4 is read in a proper order beginning from the first stripe 5a, then reading data stripes 5, and finally last stripe 5b. The example illustrated in Figure 2 correspond~ mainly to a perpendicular setting of beam 7 ayainst label 3. This is not oompulsory for carrying out a reading. If label 3, which is carried by a header 17 attached t~ the roll core r includes stripe material with a retro-reflecting property, that is, giving reflection in the direction of the incoming beam, beam 7 does not have to hit label 3 perpendicularly.
The invention is not limited to the embodiment shown, but several modifications thereof are feasible within the scope of the attached claims. The turning of scanning plane 8 around axis 11, for instance, may also be carried out by varying the optics of transmitter-receiver 6.

The invention will now be described, by way of example, with reference to the accompanying drawing, in which - Figure l schematically shows a perspective view of one embodiment of the inventionf and - Figure 2 shows a detail of Figure l.
In the drawing, reference numeral l refers to a big paper roll, at the end 2 of which an identification label 3 is ., attached. Label 3 includes for roll identification a bar code 4 formed by parallel stripes 5. For identifying the fore and tail end of the code, it comprises a first stripe 5a and a last stripe 5b of special character. For reading code 4, there is an optical transmitter-receiver 6, ~or instance, a laser device transitting a n~rrow, collimated beam 7. Beam 7 scans rapidly over a restricted scanning angle a in a plane 8. The contact point 9 of beam 7 on roll 1 moves along a line 10 at the roll end surface 2.
Transmitter-receiver 6 is rotatably supported on a carrier 16, so that scanning plane 8 can be turned around an axis 11 lying in said plane. The angular speed of the scanning beam movement continuously to and fro is considerably higher than the turning speed of plane 8 around axis 11~
A device 13 or measuring roll di~meter is schematically illustrated, as well as means 15 for vertical movement 15a of device 13~ The diameter measuring device may, for instance, be a mechanical slide gauge, the rigid jaw of which is the pair o roll supporting drums 12. The distance between the rigid jaw and the movable jaw setting on~.o the top of the roll mantle is registered electrically and the measured value is transferred to a computer unit governing the process. Transmitter-receiver 6 is adjusted in a vertical direction according to the diameter data of roll 1, so that the center lOa of the scanning angle will come close to the lon~itudinal axis of the roll 1. For vertical movement of measuring device 13 and transmitter-receiver 6 there are displacement means 15 and L4, for instance, chain or bel~ drives. They can be intercon-nected, so that movement 14a is about one half of movement 15a~ The interconnection members are not shown in the drawing. Conventional means can be used for ~his purpose.
As a result of the turning of scanning plane 8, scanning line 10 turns around a point lOa, as shown by arrows 18 in Figure 2. Since the to and fro scanning speed of beam 7 is considerably higher than the turning speed of plane 8, several readings of the code are made. Thereby, at least one reading ;s carried out so, that code 4 is read in a proper order beginning from the first stripe 5a, then reading data stripes 5, and finally last stripe 5b. The example illustrated in Figure 2 correspond~ mainly to a perpendicular setting of beam 7 ayainst label 3. This is not oompulsory for carrying out a reading. If label 3, which is carried by a header 17 attached t~ the roll core r includes stripe material with a retro-reflecting property, that is, giving reflection in the direction of the incoming beam, beam 7 does not have to hit label 3 perpendicularly.
The invention is not limited to the embodiment shown, but several modifications thereof are feasible within the scope of the attached claims. The turning of scanning plane 8 around axis 11, for instance, may also be carried out by varying the optics of transmitter-receiver 6.
