Description
Technical field
The utility model relates to printer technology field, relates in particular to a kind of image detection device of multi-joint document printing machine.
Background technology
A document is formed by many points of document bookbindings, and every a document comprises color difference and identical multi-joint (the being multiple) printing sheets of pattern, as two receipts or other documents in duplicates, triplicate form, tetrad list, 5-linked list etc.At present, generally integrate printing for printing the multi-joint document printing machine of multi-joint document, gather leaves of a book and stamp multi-functional.
Traditional multi-joint document printing machine is in the time gathering leaves of a book the multi-joint paper after printing, whether the common printing quality that adopts manual type to estimate multi-joint paper is intact, whether upper and lower stacked is regular, or adopting image detection device 1(is as shown in Figure 2 camera or video camera), by its taking lens 12 and flasher 11, to upper and lower stacked glistening in the uppermost one page paper of multi-joint paper a, take, and the image of shooting is reached to control module and the display unit of printing machine, whether the printing quality that is judged multi-joint paper by control module is intact, whether upper and lower stacked is regular.The problem that these two kinds of modes exist is: the image detection device of traditional multi-joint document printing machine is owing to just uppermost one page paper being glistened, being taken, and due to the reflection action of uppermost one page paper, it is poor to make in the perspectivity of all the other paper below, therefore the image that can only see clearly uppermost one-page clearly, paper image ratio is below fuzzyyer; And manual range estimation is to check that by contact pin mode whether printing is neatly clear, both can not check clearly the picture quality of every of multi-joint document print product and well-behaved accuracy rate, can only check roughly.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of multi-joint document printing machine image detection device is provided, this image detection device simultaneously high definition gather plurality of sheets of paper overlapping after image and rule separately, provide image and well-behaved accurately more clearly at open state to multi-joint document printing machine.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of multi-joint document printing machine image detection device, comprise: for detection of the image detection device of upper and lower stacked multi-joint document direct picture, described image detection device comprises taking lens, described image detection device is electrically connected with control module and the display unit of printing machine respectively, the below at the back side of described multi-joint document is provided with back side light source, the light direction of described back side light source is towards the back side of described multi-joint document, the position of described back side light source is corresponding up and down with the position of described taking lens.
As preferably, described back side light source adopts stroboscopic lamp.
Owing to having adopted technique scheme, multi-joint document printing machine image detection device of the present utility model, remove the flasher of the traditional images checkout gear that is positioned at top, multi-joint document front, and below the multi-joint document back side, be provided with back side light source, the light direction of this back side light source is towards the back side of multi-joint document, and the position of the position of back side light source and the taking lens of image detection device is corresponding up and down, in the time that multi-joint document printing machine is in open state, the back side of the multi-joint document of light directive that back side light source sends, see through every page of paper of multi-joint document from bottom to top, thereby strengthen the perspectivity of upper and lower stacked multi-joint document paper, make the image detection device that is positioned at top, multi-joint document front in the time utilizing its taking lens to capture, can not only take clearly the image that is positioned at uppermost one page paper, and can take clearly the image that is positioned at all the other paper below, image detection device reaches the multi-joint document image of taking and rule control module and the display unit of printing machine, operator can easily see image and the rule of multi-joint document print product under non-stop-machine state by display unit, and whether control module is intact according to the printing quality of multi-joint paper, whether upper and lower stacked is regular, thereby can correct in time the printing process of upstream, defeated paper operation, guarantee is provided for improving the quality of products.Meanwhile, it is high, simple in structure that multi-joint document printing machine image detection device of the present utility model has functional reliability, low cost and other advantages.
