Abstract
This utility model provides a kind of repeated-rail printer measuring and controlling, measurement control module is set up in PLC, two detection gratings are one in front and one in back installed in the anterior heavy rail rollgang side of measurement roller, detection grating connection measurement control module, measurement control module outfan respectively with measurement roller converter and printhead converter connecting communication.This utility model can effectively solving printhead and the nonsynchronous problem of heavy rail speed, improve the precision of position measurement and control, it is ensured that hot padding position is uniform, and hot padding character becomes apparent from, so as to meet the prescription of heavy rail hot padding printing.
Description
Technical field
This utility model belongs to automatic control technology field, the printer measurement control of more particularly to a kind of heavy rail hot padding
Device.
Background technology
At present, domestic Rail Production line is more is designed with producing 100 meters as standard, according to the Ministry of Railways to rail hot padding
Standard, the quality, position to rail hot padding character all have higher requirements.This requires that the printhead of repeated-rail printer must be led
Dynamic speed sync and the position measurement realized with hot rail.Original repeated-rail printer is by PLC, measurement roller, measurement motor, survey
Amount roller converter, printhead, print motor and printhead converter and constituted, find in long-term print procedure, its printhead and
Often there is speed asynchrony phenomenon in operating heavy rail Jing, causes huge frictional force to damage measurement roller surface, bearing and other portions
Part, while causing position measurement inaccurate, hot padding position is uneven, the unsharp defect of hot padding character, thus only according to
Make the printing type that printhead is passively followed meet heavy rail hot padding printing by the frictional force of rail and printhead
Require.
The content of the invention
This utility model provides a kind of repeated-rail printer measuring and controlling, its objective is to solve printhead and heavy rail speed
Nonsynchronous problem, improves the precision of position measurement and control, it is ensured that print quality.
It is that, up to this purpose, this utility model takes following technical solution：
A kind of repeated-rail printer measuring and controlling, including PLC, measurement roller converter and printhead converter, in PLC
Measurement control module is set up, two detection gratings, detection are one in front and one in back installed in the anterior heavy rail rollgang side of measurement roller
Grating connection measurement control module, measurement control module outfan are connected logical with measurement roller converter and printhead converter respectively
News.
The beneficial effects of the utility model are：
This utility model can effectively solving printhead and the nonsynchronous problem of heavy rail speed, raising position measurement and control
Precision, it is ensured that hot padding position is uniform, and hot padding character becomes apparent from, so as to meet the prescription of heavy rail hot padding printing.
Description of the drawings
Fig. 1 is that repeated-rail printer measuring and controlling constitutes schematic diagram.
In figure：Measurement roller converter 1, measurement control module 2, PLC3, measurement motor 4, detection grating II 5, detection grating I
6th, heavy rail 7, rollgang 8, measurement roller 9, printhead 10, printing motor 11, printhead converter 12.
Specific embodiment
As seen from Figure 1, this utility model repeated-rail printer measuring and controlling, be original measurement roller converter 1,
On the basis of PLC3, measurement motor 4, measurement roller 9, printhead 10, printing motor 11, printhead converter 12, increase in PLC3
If measurement control module 2, while on the inside of the heavy rail rollgang 8 of 9 front portion of measurement roller, i.e., it is previous with 4 homonymy one of measurement motor
It is mounted with that detecting that grating I 6 and detection grating II 5, detection grating I 6 and detection grating II 5 connect respectively sets up in PLC3 afterwards successively
Measurement control module 2, the outfan for measuring control module 2 is connected with measurement roller converter 1 and printhead converter 12 respectively
Communication.Measurement roller converter 1 by the connection measurement roller 9 of measurement motor 4, measurement roller 9 be arranged on adjacent two rollgangs 8 it
Between, printhead converter 12 connects printhead 10 by printing motor 11.
It is of the present utility model measurement control process be：
When heavy rail 7 is run to detection grating I 6, detection signal is sent to PLC3, PLC3 control measurements by detection grating I 6
Motor 4 drives measurement roller 9 to rotate, to ensure to make the speed of measurement roller 9 synchronous with the speed of service of heavy rail 7.
When heavy rail 7 is run to detection grating II 5, PLC3 control measurement rollers 9 move the bottom for propping up heavy rail 7 upwards, this
When measure roller 9 mode of operation walked around to the passive rotation driven by heavy rail, the rotation installed in measurement motor 4 by active rotation
Speed and position data are delivered to the input module of printhead converter 12 by transformator and encoder.
Printhead converter 12 compares and comes from the speed data of the rotary transformer measurement that measurement roller 9 is installed, prints electricity
The speed data of the rotary transformer measurement that machine 11 is installed, 10 rotary speed of speed closed loop real-time control printhead and measurement roller 9
Speed is consistent.
The position data for coming from the encoder measurement that measurement roller 9 is installed is delivered to by the output module of printhead converter 12
The counting module of PLC3.The pulse signal for often counting completely setting quantity means that heavy rail 7 has passed through 1,9 surface of measurement roller girth
Distance.So that heavy rail 7 is obtained by measuring the length of roller 9, drive printhead 11 at the different extension position of whole heavy rail 7
Drop to the surface of thermogravimetric rail 7, synchronous rotary completes hot padding work.
