Abstract

The utility model discloses a paper-deviation-rectifying device applied to continuous printing. The device includes sheets of paper (1) on which color codes are printed, a paper-guide roller (4) and a motor (3) which drives the paper-guide roller (4) to rotate. The device is characterized in that a CCD tracking electric eye (2) used for identifying the color codes on the sheets of paper (1) are arranged above the moving direction of the sheets of the paper (1). The CCD tracking electric eye (2) converts an identification signal into a starting instruction of the motor (3) so that the rotating direction of the motor is controlled. In the continuous printing of roll paper, printing of continuous tracking lines on the paper is not needed and demands of the deviation-rectifying tracking eclectic eye are met. Tracking demands of the electric eye can be met only by printing discontinuous color codes at blank places of printing faces so that wastes caused by an increase of the size of the printing paper because the continuous tracking lines are printed are avoided.

Description

A kind of paper deviation rectifying mechanism be applied in continuous printing

Technical field

The utility model relates to deviation correction mechanism, specifically a kind of paper deviation rectifying mechanism be applied in the roll web continuous printing.

Background technology

Because web press belongs to the unit type printing pattern, from uncoiling to finishing printing, the walking path of whole paper is very long, Chang Dezhi like this road, paper occurs that skew is inevitable, if do not take correction, printed patterns is imprinted on paper and just there will be irregular skew, next procedure can't be processed, so, in order to guarantee print quality, just need to carry out real-time deviation correcting to the paper of advancing, existing deviation correction mechanism structure need to be in a continuous tracker wire of printed patterns one side blank space printing, meet the tracer request of deviation correction mechanism, so to increase the paper printing breadth, the extra manufacturing cost that increases.

The utility model content

The utility model is to solve the existing weak point of above-mentioned prior art, a kind of paper deviation rectifying mechanism be applied in continuous printing is provided, and this mechanism can utilize the aberration of printed patterns itself or realize deviation-correcting function at the colour code that the printed patterns blank space stamps interruption.

The utility model solves its technical problem and takes following technical scheme:

A kind of paper deviation rectifying mechanism be applied in continuous printing, the motor that comprises the paper, dancing roll and the rotation of driving dancing roll that are printed on colour code, its design feature is, the top that is positioned at the paper direct of travel is provided for identifying paper colouring target CCD and follows the tracks of electric eye, described CCD follows the tracks of electric eye and identification signal is converted to the enabled instruction of motor, for controlling motor rotation.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the utility model can utilize the aberration of printed patterns itself or realize deviation-correcting function at the colour code that the printed patterns blank space stamps interruption, to reduce the colour code printing format, reduces printing cost.

2, the utility model adopts CCD probe identification typographic(al) mark, is furnished with the fuzzy memory function of computer, when colour code occurring simultaneously, computer sends instruction, and the instruction of being rectified a deviation, when occurring being interrupted colour code, while there is no colour code, computer is remembered wait state in dormancy, and correction stops waiting for.

The accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Number in the figure: 1 paper, 2 CCD follow the tracks of electric eyes, 3 motors, 4 dancing rolls, 5 dancing rolls arrow, 6 colour codes, 7 wallboards, the 8 paper arrow of advancing of advancing.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further illustrated.

As shown in Figure 1, deviation correction mechanism, comprise the paper 1 that is printed on colour code 6, identification colour code CCD follows the tracks of electric eye 2, paper is advanced by paper arrow 8 direction indications of advancing, dancing roll 4 one ends and wallboard 7 are rotationally connected, the other end is connected with drive motors, dancing roll 4 rotates by the advance direction of arrow 5 of dancing roll, paper first passes through dancing roll 4, arrive again CCD and follow the tracks of electric eye 2, CCD provides side-play amount and direction instruction after following the tracks of electric eye 2 identification colour codes 6, this instruction becomes motor direct of travel and amount of travel through conversion, traction dancing roll 4 is done corresponding movement, thereby drive paper 6 is made skew and is advanced, meet CCD and follow the tracks of electric eye 2 identification requirement.

Follow the tracks of the printing colour code and can use in printed patterns, the pattern boundaries that print color is larger with printing bottom surface contrast, the tracking colour code that also can be interrupted in the printing of printed patterns blank space.

Using method: manually first identify in printed patterns, the tracking colour code whether existence can directly utilize, if not then the colour code be interrupted in the printing of printed patterns blank space, after the identification colour code, colour code is placed under electric eye, after starting electric eye recognition memory program, and will identify content and be stored in the electric eye memory.

Start printing machine, paper is advanced by set direction, colour code is after electric eye, and electric eye can provide a certain amount of and deviation correcting signal direction, advances the deviation-correcting function that motor traction paper reverse roller completes paper.

Claims

1. the paper deviation rectifying mechanism be applied in continuous printing, comprise paper (1), the dancing roll (4) that is printed on colour code and the motor (3) that drives dancing roll (4) to rotate, it is characterized in that, the top that is positioned at paper (1) direct of travel is provided for identifying paper (1) colouring target CCD and follows the tracks of electric eye (2), described CCD follows the tracks of electric eye (2) and identification signal is converted to the enabled instruction of motor (3), for controlling motor rotation.
