As shown in fig. 1 and fig. 2, the invention provides a full-automatic taking-out control system for a gypsum board mask paper joint plate, the embodiment of the invention can accurately measure to reduce the error calculation of the mask paper joint, and is more favorable for realizing position measurement and calculation of the paper joint, and the accurate length measurement system can also measure and calculate the use amount of the mask paper, so that the system has the advantages of wide use, simplicity, convenience for installation, and more accurate and reliable use process.
Meanwhile, the joint position of the facing paper is calibrated, so that the joint position of the facing paper is always positioned at the head position of the next roll of facing paper for active paper receiving, the sampling success rate is improved, and the gypsum board containing the facing paper joint can be removed quickly and effectively.
The method specifically comprises the following steps: the automatic paper receiving and cutting device comprises a master control processing system 1, an automatic paper receiving unit 2, a length detecting unit 3, a cutting statistical unit 4, a cutting information transmission unit 5, a paper joint cutting length setting unit 6 and a gypsum board automatic sampling device 7, wherein the master control processing system 1 is used for controlling joints of the protective paper, gypsum board cutting and joint gypsum board removing in sequence.
Wherein automatic paper receiving unit 2 detects the automatic online paper receiving operation that realizes going up mask paper and mask paper down through the thickness to the incomplete book of scroll, and this embodiment is equipped with laser ranging unit in the last below of automatic paper receiving unit 2, and laser ranging unit calculates the diameter of the incomplete book of mask paper according to the distance between two laser emission points and the distance of two laser emission points to the mask paper scroll.
However, due to the transmission tightness factor of the protective paper on the equipment and the self expansion coefficient of the protective paper, the accuracy of length estimation by using the laser ranging unit is poor, and particularly, the smaller the diameter of the residual roll of the protective paper is, the worse the estimation accuracy of the length by using the laser ranging unit is, so that the timeliness and accuracy of the online automatic joint of the protective paper is seriously influenced.
The length detection unit 3 of the present embodiment is closely arranged at the side of the automatic paper receiving unit 2 along the transmission direction of the protective paper, the control relationship between the length detection unit 3 and the automatic paper receiving unit 2 is related, and the length detection unit 3 is used for converting the number of rotation turns of the transmission roller into the length of the protective paper and calculating the transmission use length of the protective paper.
The reduction ratio, i.e. the transmission ratio of the reduction gear, is one of the transmission ratios, and refers to the ratio of the instantaneous input speed to the output speed in the reduction mechanism, and the formula of the reduction ratio is defined as: the reduction ratio is equal to the number of driven gear teeth and divided by the number of driving gear teeth; the reduction ratio is input rotating speed and output rotating speed or the reduction ratio is driven wheel diameter and driving wheel diameter;
in general, in order to avoid an error caused by the high-speed rotation of the driven wheel, the error calculation of the facing paper joint is reduced by the accurate measurement of the encoder 303, and the driven wheel has a small rotational speed, a large diameter, and a large number of teeth.
The vertical extension board that is used for supporting drive roll wheel 302 both ends is equipped with to mask paper direction of delivery both sides, drive roll wheel 302 horizontal distribution is at the upper and lower surface of mask paper, drive roll wheel 302 is rotatory under drive assembly's drive, drives the mask paper through the frictional force between with the mask paper and transmits to production cutting end.
As shown in fig. 4 and 5, the variable frequency power assembly includes a variable frequency motor 10, a driving gear 11 connected to an output shaft of the variable frequency motor 10, and a driven gear 13 connected to the driving gear 11 through a transmission belt 12, wherein a diameter of the driven gear 13 is greater than a diameter of the driving gear 11.
The diameter of the driven gear 13 is larger than the diameter reduction ratio of the driving gear 11, the input rotating speed of the driving gear 11 is larger than the output rotating speed of the driven gear 13, and the rotating speed of the driving gear connected with the variable frequency motor 10 is far larger than the rotating speed of the driven gear 13, so that the driving gear 11 and the driven gear 13 form a speed reducer.
Two supporting plate frames 14 which are distributed oppositely are arranged on two sides of the facial tissue, a group of transmission roller wheels 302 which are vertical to the conveying direction of the facial tissue are arranged between the supporting plate frames 14, and the transmission roller wheels 302 are connected through a synchronous transmission assembly 16.
The diameters of the two drive rollers 302 are the same, and the rotating shafts of the two drive rollers 302 are provided with encoders 303.
In the embodiment, the transmission roller above the mask paper passes through the supporting plate frame 14 and is fixedly connected with the driven gear 13, and the rotation speed of the driven gear 13 is low, so that the rotation speed of the transmission roller 302 is also low, and the large measurement error of the encoder 303 caused by the large inertia of the transmission roller 302 during high-speed rotation is avoided, and the error calculation of the mask paper joint is reduced through the accurate measurement of the encoder 303, which is more favorable for realizing the position measurement of the paper joint.
In the embodiment, the number of transmission turns of the transmission roller 302 is counted by the encoder 303, so that the transmission length of the face-protecting paper driven by the transmission roller 302 can be calculated.
In addition, the transmission roller 302 is driven by the driven gear 13 to continue to transmit, and due to the influence of expansion and stretching of the mask paper, when the stretching force of the mask paper is large, the pressure of the transmission roller 302 on the mask paper is large, and the mask paper is easy to break, so that the transmission roller 302 is designed to be in a springing mode in the embodiment, and the pressure adaptability of the mask paper is modified.
Be equipped with on the supporting plate frame 14 and be used for cutting cut 17, the vertical limit of cutting cut 17 is equipped with spacing track 18, the inside of spacing track 18 is equipped with and is used for bearing drive roll wheel 302's compensation movable block 19, install through compression spring 21 the upper end of compensation movable block 19 on the cutting cut 17.
Two bearing hole grooves 20 are formed in the compensation moving block 19, the transmission roller 302 rotates around the bearing hole grooves 20, and the distance between the upper transmission roller 302 and the lower transmission roller 302 is equal to the thickness of the surface protecting paper.
The transmission roller 302 above the facing paper is fixedly mounted on the center of the driven gear 13 through the compensation moving block 19.
When the surface tension of the mask paper is too high, the mask paper pulls the transmission roller 302, and the compression spring 21 adaptively drives the transmission roller 302 to bounce up and down, so that the tension change of the mask paper is compensated.
The surface movable mounting of supporting plate frame 14 has and is used for adjusting driving belt 12's tension adjusting rod 15, tension adjusting rod 15's end be equipped with driving belt 12 contacts's supporting roller 23, be equipped with tension spring 22 on the spring base on tension adjusting rod 15 mounted position place plumb line, tension spring 22's both ends are installed respectively spring base with on the tension adjusting rod 15.
Since the surface tension of the driving belt 12 is changed by the driving roller 302 bouncing up and down, the present embodiment compensates for the displacement of the driving roller 302 by the inclination of the tension adjusting lever 15.
Therefore, in the embodiment, the rotation speed of the transmission roller wheel 302 is reduced, so that the large measurement error of the encoder 303 caused by large inertia when the transmission roller wheel 302 rotates at a high speed is avoided, and the error calculation of the facing paper joint is reduced through the accurate measurement of the encoder 303.
Meanwhile, the transmission roller 302 can bounce up and down in a certain range, so that the device is suitable for the mask paper with different tensions, and the situation that the mask paper is broken due to overlarge pressure on the mask paper is avoided, thereby realizing the accurate measurement of the length of the mask paper.
The encoder 303 of this embodiment is configured to calculate the number of rotation turns of the transmission roller 302, and calculate the transmission length of the cover paper according to the number of rotation turns of the transmission roller 302, so as to determine the joint operation of the cover paper according to the length of the remaining cover paper.
According to the above, the automatic paper receiving unit 2 calculates the residual diameter of the paper roll of the facial tissue by using the laser ranging unit, but due to the transmission tightness factor of the facial tissue on the equipment and the self expansion coefficient of the facial tissue, the purpose of accurate calculation cannot be achieved by using the original laser ranging unit for estimation, and particularly under the condition that the diameter of a scroll of the facial tissue is smaller and smaller, the measurement error of the laser ranging unit is larger, and the residual length of the facial tissue cannot be accurately judged in time. Therefore, the remaining length of the face-protecting paper can be determined only by determining the relation between the diameter of the scroll of the face-protecting paper and the length of the face-protecting paper, and the problems of material waste caused by too early joint operation of the face-protecting paper or face-protecting paper interruption caused by too late joint operation of the face-protecting paper are avoided.
Therefore, in the embodiment, the measurement of the transmission length of the face protection paper is combined with the measurement of the residual diameter of the face protection paper scroll, the length detection unit 3 drives the face protection paper to transmit and simultaneously detects the transmission length of the face protection paper in real time, the automatic paper receiving unit 2 detects the thickness of the face protection paper scroll residual roll, and the transmission length relation corresponds to the thickness of the face protection paper scroll residual roll one by one.
When the laser ranging unit detects that the diameter of the residual roll of the face protection paper roll reaches the expected joint diameter, the master control processing system 1 controls the length detection unit 3 to reset and re-meter the transmission length of the face protection paper, and the length of the face protection paper converted from the expected joint diameter is larger than the distance from the paper receiving point of the automatic paper receiving unit 2 to the cutter edge of the cutting unit.
The transmission length measured by the length detection unit 3 reaches the paper splicing control data, the paper splicing control data is the same as the distance between the paper splicing point of the automatic paper splicing unit 2 and the cutter edge of the cutting unit, and the master control processing system 1 controls the automatic on-line paper splicing of the automatic paper splicing unit 2. In this case, the paper splicing length in the present embodiment is specifically a length difference between the length of the cover paper in terms of the expected joint diameter and the paper splicing control data.
The cutting statistical unit 4 is used for cutting the wet gypsum boards according to the standard length and counting the number of the gypsum boards produced by each roll of the protective paper; the number of gypsum boards correspondingly produced by each roll of the protective paper and the position of each roll of the protective paper corresponding to the protective paper joint are counted through the cutting action times of the cutter.
Cut off statistical unit 4 simultaneously and be used for the correction automatic paper receiving unit 2's paper receiving operation, cut off statistical unit 4 according to the folding redundant distance between the automatic joint position of mask paper and the limit port of mask paper, adjust length detecting element 3's paper receiving control data extremely the incomplete book limit diameter of mask paper is the refill diameter, total control processing system 1 control automatic paper receiving unit 2 realizes no redundant folding paper receiving work just automatically.
According to the above, the length of the facing paper joint controlled by the automatic paper receiving unit 2 and the length detecting unit 3 in a first matching mode is too large, so that the gypsum board with the facing paper joint is adjacent to other normal gypsum boards, the gypsum board with the facing paper joint is inconvenient to remove waste, and waste of the gypsum board material is caused.
The cutting statistical unit 4 is specifically the composition of cutting unit and cutting number of times statistical unit, and the cutting unit mainly utilizes the cutter to cut the shaping according to same length size to wet gypsum board, and cutting number of times statistical unit makes statistics of the gypsum board number that a mask paper roll can produce, makes statistics of the mask paper joint of first cooperation control, and for the gypsum board of conventional specification 2.4 meters, the regular stop in upper mask paper joint position is the third last piece of upper mask paper cocut volume of cutting totally, and the lower mask paper joint is the second last piece of lower mask paper cocut volume of regular upper mask paper cocut volume of cutting totally.
Therefore, in the embodiment, the position of the joint of the face protection paper is counted for multiple times, the paper splicing length of the tail end of the specific face protection paper roll of the face protection paper joint is determined, namely the cutting statistical unit 4 determines the folding redundant distance between the automatic joint position of the face protection paper and the limit port of the face protection paper according to the folding redundant distance.
The purpose of the disconnection statistic means 4 in the present embodiment is to: the device is used for cutting the wet gypsum boards according to the standard length, counting the number of the gypsum boards produced by each roll of the facing paper, and counting the number of the gypsum boards correspondingly produced by each roll of the facing paper and the position of each roll of the facing paper corresponding to the facing paper joint through the cutting action times of the cutter.
And the cutting information transmission unit 5 resets the joint position of the facing paper to the tail end position of each facing paper according to the statistical result of the cutting statistical unit 4, so that the redundant folding length of the joints of the two facing papers is basically zero, and when the cutting statistical unit 4 cuts off the gypsum board, the joint containing the facing paper is always positioned on the frontmost gypsum board produced by one roll of facing paper, so that the subsequent identification and elimination processing of the gypsum board containing the joint is facilitated.
