Abstract

The utility model discloses a rapid pre-registering device for a printing machine, which consists of an embedding-type DSP chip, a FPGA part that is connected with each color bit servo motor of the printing machine, and a host computer that is respectively connected with the DSP chip and the FPGA part, wherein, the DSP chip is connected with the FPGA part, and the DSP chip and the FPGA part form a pre-registering control unit. The rapid pre-registering device has simple structure, low cost, simple and convenient operation, high registering precision and rapid speed, and can completely realize the automatic control; the pre-registering control unit can automatically calculate the rotation phase required for each roller, and is free from performing the restoring zero operation on the roller, thereby really realizing the high-precise pre-registration and entering into the automatic registering printing status.

Description

A kind of fast pre-registration device that is used for printing machine

Technical field

The utility model relates to textile printing and dyeing device technique field, especially relates to a kind of fast pre-registration device that is used for printing machine.

Background technology

At present, the existing mechanical transmission printer all will carry out pre-alignment adjustment before the operation after each plate change, to reduce the waste product of initial stage chromatography.If pre-alignment is inaccurate, then cause equipment needs very long band paper running times, thereby generation needs waste product.All adopted rotary encoder to positioning mostly in the past, the adjustment period of dancer between punishment in advance long, thereby complex operation, spended time is long and it is not high to adjust precision, in addition, the printing loss that causes is also bigger.To sum up, adopt artificial pre-alignment mode, not only complicated operation, position error are big, and it is slow dynamically to regulate the speed.

The utility model content

Technical problem to be solved in the utility model is at above-mentioned deficiency of the prior art, a kind of fast pre-registration device that is used for printing machine is provided, it is simple in structure, with low cost, use is easy and simple to handle and alignment precision is high, speed is fast, can realize automatic control fully.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of fast pre-registration device that is used for printing machine, it is characterized in that: FPGA device that joins by embedded DSP, with the servo controller of each color bits servomotor of printing machine and the host computer that joins with dsp chip and FPGA device are respectively formed, and described dsp chip connects the FPGA device and the two forms pre-alignment control module.

Described dsp chip is chip DSP65F803BU80.

Described FPGA device is chip EP1C3T100.

The utility model compared with prior art has the following advantages, and 1, simple in structure, with low cost and use easy and simple to handle; 2, alignment precision height and speed are fast, can realize automatic control fully, and whole control process is simple and convenient, quick, at first by host computer each pre-alignment parameter are inputed to embedded DSP; Simultaneously, host computer sends pre-alignment fill order to the FPGA device, receive the fill order of pre-alignment when the FPGA device after, synchronously the servomotor of printing machine is controlled, the material length between two version rollers of printing machine is adjusted into edition integral multiple of roller girth the most at last.To sum up, the utility model can be handled automatically by pre-alignment control module and draw the phase place that each edition roller need rotate, do not need again the version roller to be recovered " zero-bit " operation, thereby realize the pre-alignment of high accuracy truly, enter the register control printing state subsequently.

Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Fig. 1 is a structured flowchart of the present utility model.

Description of reference numerals:

1-dsp chip; 2-host computer; 3-servomotor;

4-FPGA device; 5-servo controller.

The specific embodiment

As shown in Figure 1, FPGA device 4 that the utility model joins by embedded DSP 1, with the servo controller 5 of each color bits servomotor 3 of printing machine and the host computer 2 that joins with dsp chip 1 and FPGA device 4 are respectively formed, and described dsp chip 1 connects FPGA device 4 and the two forms pre-alignment control module.Wherein, described dsp chip 1 is chip DSP65F803BU80, and described FPGA device 4 is chip EP1C3T100.

The course of work of the present utility model is: at first, by host computer 2 each pre-alignment parameter is inputed to embedded DSP 1, carry out analyzing and processing by each pre-alignment parameter that 1 pair of dsp chip is imported, simultaneously to FPGA device 4; Simultaneously, send pre-alignment fill order by host computer 2 to FPGA device 4, receive the fill order of pre-alignment when FPGA device 4 after, synchronously each color bits servomotor 3 of printing machine is controlled, the material length between two version rollers of printing machine is adjusted into edition integral multiple of roller girth the most at last.To sum up, the utility model can be handled automatically by pre-alignment control module and draw the phase place that each edition roller need rotate, do not need again the version roller to be recovered " zero-bit " operation, thereby realize the pre-alignment of high accuracy truly, enter the register control printing state subsequently.

The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of technical solutions of the utility model according to the utility model technical spirit.
