The automatic tracing and detecting apparatus of printing press of a kind of special print heterotypic material
Technical field
The present invention relates to the automatic tracing and detecting apparatus of printing press of a kind of special print heterotypic material.
Background technology
The stock of Idiotype often can be run at print field. Production the type stock mainly adopts segmentation modular mode to print, and each stock printing is joined after ink completes, and carries out the print system of the school between stock. Each stock that meets the requirements has correct position and space printed data, and this regulates the position to stock with regard to needing. Digital printing is joined ink system and is usually adopted the mode of supported at three point or four-point supporting that stock is carried out automatization position adjustment, the printing unit at point of suppon place has translation freedoms in F type direction, forms F type and connect between each printing unit with the sensing head installed on printing stock. In stock printing process, printing unit first parameter according to theory configure, but in fact owing to sensing head installs the existence manufacturing equal error, Controlling System needs by repeatedly putting feeding to find correct Support Position, otherwise owing to the existence of positionerror will inevitably produce extra stress and deformation, thus except affecting accurate positioning printing efficiency, also can affect printing process stability, accuracy, reliability. Therefore, must take measures improve the accurate positioning printing of stock printing working efficiency, and prevent accurate positioning printing error from producing extra-stress, deformation and printing unit and stock are caused dislocation damage, therefore, the automatic tracing and detecting apparatus of printing press that must develop a kind of special print heterotypic material could eliminate this fraud, and this is researched and developed by the present invention specially.
Summary of the invention
It is an object of the invention to join accurate positioning printing Problems existing in ink for above-mentioned Idiotype stock digital printing, it is provided that the automatic tracing and detecting apparatus of printing press of a kind of special print heterotypic material. This device comprise Power convert device, transfer table, web member, induction installation, shifting post rail, mounting block, circle embedding post, roller, grab bar, induction grippers, upper top bar, sensing head, inductance gauge, lower object survey sensor, detector, upper object survey sensor, left object survey sensor, handle adapter;Power convert device is provided with object and surveys sensor and handle adapter, Power convert device connects transfer table by moving post rail, transfer table is provided with left object and surveys sensor, and connect web member by the detector of vertical direction, web member top configuration mounting block and induction installation, the lower object of mounting block bottom is surveyed sensor and is connected with the embedding post of circle, the embedding post of circle is grabbed bar through roller with two and is connected, grab bar and connect two induction grippers by the embedding post of circle, it is connected by the embedding post of circle between induction grippers and mounting block, mounting block top is configured with sensing head, F type inside, mounting block top is provided with inductance gauge, mounting block is provided with top bar.
Described mounting block top forms F type with sensing head and is connected.

When 4, printing stock, the accurate positioning printing of sensing head printing, produces follow-up shift;
5, by printing unit, follow-up shift is compensated;
6, induction installation is locked;
7, when object surveys sensor clamping instantly, printing stock is held admittedly;
8, when the sensor of object survey instantly loosens the clamping to sensing head, printing stock is unclamped.
The useful effect of the present invention is: join accurate positioning printing Problems existing in ink for Idiotype stock digital printing, it provides the automatic tracing and detecting apparatus of printing press of a kind of special print heterotypic material.This induction installation can be followed automatically, and in very little applied external force, make the accurate positioning printing of stock. And, after school print system works completes, once release the locking switch of the accurate positioning printing mechanism of self-adaptation, just can conveniently discharge the stress-strain that printing is joined ink process and produced, by print unit automatic compensation and again locking follow accurate positioning printing mechanism, it is achieved the overall accurate positioning printing of the printing stock after tracking.
