Abstract
The invention discloses a guiding belt deviation rectifying device of a circular screen printer. The guiding belt deviation rectifying device comprises a guiding belt, a tension roller, a driving roller, a deviation rectifying motor, a camera and a controller. The guiding belt is arranged on the tension roller and the driving roller in a tensioning mode and carries out transmission through the driving roller. A coloring coating layer with the same width as the guiding belt is arranged on the outer surface of the driving roller. During normal operation, the guiding belt completes covers the color coating layer. The camera collects images of the two side ends of the guiding belt on the driving roller in real time. The controller determines whether the coloring coating layer protrudes out of the guiding belt according to the images collected in real time, whether the guiding belt deviates is determined, a control order is obtained, and the control order is sent to the deviation rectifying motor. The deviation rectifying motor carries out deviation rectifying on the driving roller according to the control order. According to the guiding belt deviation rectifying device of the circular screen printer, the images of the coloring coating layer are collected, whether the guiding belt deviates can be easily know by comparing, the direction of deviating can be easily known by comparing, and detecting of guiding belt deviation is very easy.
Description
Technical field
The present invention relates to textile technology, relate in particular to a kind of conduction band deviation correcting device of circular screen printer.
Background technology
Conduction band (print guide belt) is the critical component of circular screen printer, the quality of print guide belt and be steadily whether to determine printing quality and the principal element in conduction band life-span in running.Print guide belt requires to operate steadily, and control system can be to carrying out automatic deviation correction control to conduction band.
Existing conduction band deviation correcting device coordinates microswitch and correction motor to realize correction by deviation rectification roller, spy limit roller, and specific works process is as follows: under the impact of conducting oneself with dignity, visit limit roller and press closer conduction band, and by connecting rod control microswitch; In the time of conduction band sideslip, the switch control closing of contact of the microswitch of corresponding side, correction electric machine rotation, slightly swings deviation rectification roller, corrects conduction band sideslip; When conduction band does not have sideslip, open the switch control contact of two microswitches, and correction motor does not rotate.
The control of above-mentioned deviation correcting device is comparatively sensitive, but complex structure once break down, must stop work and keep in repair for a long time, be unfavorable for produce carry out.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of simple in structure, be convenient to the conduction band deviation correcting device of the circular screen printer of safeguarding, it can be used as the conduction band deviation correcting device that a kind of precision is lower and uses for a long time, also can assist existing conduction band deviation correcting device to assist correction.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of conduction band deviation correcting device of circular screen printer, comprise conduction band, jockey pulley, drive roll, correction motor, camera and controller, described conduction band is stretched on jockey pulley and drive roll, also by drive roll transmission, is provided with the colored film equating with conduction band width on the outer surface of drive roll; When normal operation, conduction band covers colored film completely;
Described camera carries out Real-time Collection to the image of conduction band two side ends on drive roll, and sends the image of Real-time Collection to controller;
Described controller show according to the image of Real-time Collection whether colored film protrudes conduction band, determines whether sideslip of conduction band, obtains control command, and this control command is sent to correction motor;
Described correction motor is rectified a deviation to drive roll according to control command.
Preferably, the color of described colored film is red, green or blue.
Certainly colored film also can not be arranged on drive roll, and is arranged on jockey pulley, and now described camera just carries out Real-time Collection to the image of conduction band two side ends on jockey pulley.
Said apparatus, by camera, the image of conduction band two side ends on drive roll/jockey pulley is carried out to Real-time Collection, analyze colored film through controller again and whether protrude conduction band, can be easy to compare out whether occur whether sideslip and towards which side sideslip of conduction band, very simple to the detection of conduction band sideslip.Meanwhile, the structure of said apparatus is comparatively simple, only needs to rely on circular screen printer to design the position of colored film and the position of camera, safeguards and regulates all very simple; Can design separately for controller, realize communication by circuit, can not produce the problem of shutdown maintenance.
Beneficial effect: the conduction band deviation correcting device of cylinder printing machine provided by the invention, by the collection to colored film image, can be easy to compare out whether occur whether sideslip and towards which side sideslip of conduction band, very simple to the detection of conduction band sideslip.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Be illustrated in figure 1 a kind of conduction band deviation correcting device of circular screen printer, comprise conduction band 1, jockey pulley 2, drive roll 3, correction motor, camera and controller, described conduction band 1 is stretched on jockey pulley 2 and drive roll 3, also by drive roll 3 transmissions, is provided with the colored film 4 equating with conduction band 1 width on the outer surface of drive roll 3; When normal operation, conduction band 1 covers colored film 4 completely;
Described camera carries out Real-time Collection to the image of conduction band 1 two side ends on drive roll 3, and sends the image of Real-time Collection to controller;
Described controller show according to the image of Real-time Collection whether colored film 4 protrudes conduction band 1, determines whether sideslip of conduction band 1, obtains control command, and this control command is sent to correction motor;
Described correction motor is rectified a deviation to drive roll 3 according to control command.
Preferably, the color of described colored film 4 is red, green or blue.
The another kind of schemes different from said structure are: described colored film is arranged on jockey pulley 2, and described camera carries out Real-time Collection to the image of conduction band 1 two side ends on jockey pulley 2, and other are identical.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
