Abstract
The utility model relates to a planographic printing press pneumatic locating device. The planographic printing press comprises a printing press operating platform. The pneumatic locating device is installed on the printing press operating platform so as to locate a printing sheet. The pneumatic locating device comprises a locating pin, an air cylinder, a control valve, an air pipe and a switch. The air cylinder is connected with one end of the locating pin. The printing sheet is connected with the other end of the locating pin. The air cylinder is connected with the control valve through the air pipe. The switch is connected with the control valve. The control valve is arranged on the printing press operating platform. Compared with the prior art, the planographic printing press pneumatic locating device has the advantages of being high in repeated locating accuracy, safe, reliable, flexible, convenient to use and the like.
Description
Technical field
The utility model relates to a kind of positioner, especially relates to a kind of lithographic press pneumatic power positioner.
Background technology
Lithographic press is in the multiplex priting process, and the chromatography location is that planographic is crucial always.The way of originally always keeping to the side to locate with cross is printed, because sheet material appearance and size difference, it is improper to place when also having by the position, cause scrap larger.It is more particularly to print number, and qualification rate is just lower, so need to seek a kind of positioner that there is defective in prior art that overcomes.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of repetitive positioning accuracy high, safe and reliable, flexible lithographic press pneumatic power positioner for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of lithographic press pneumatic power positioner, described lithographic press comprises printer table, described pneumatic power positioner is installed on the printer table printed sheet material is positioned, described pneumatic power positioner comprises pilot pin, cylinder, control valve, tracheae and switch, a described end pilot pin is connected with cylinder, the other end is connected with printed sheet material, described cylinder is connected with control valve by tracheae, described switch is connected with control valve, and described control valve is arranged on the printer table.
Be provided with electric wire between described switch and the control valve.
Described cylinder is provided with two, connects respectively a pilot pin on each cylinder.
Described printed sheet material is provided with locating hole, and described pilot pin is connected with printed sheet material by this locating hole.
Compared with prior art, the utlity model has following advantage:
1) the utility model device characteristic repetitive positioning accuracy is high, and flexible, operating efficiency and product quality obviously improve, and has solved in the past because multiple tracks chromatography positioning accuracy is low to cause product rejection large the difficult problem that qualification rate is low;
2) the utlity model has the variation of sheet material appearance and size and also can not cause the low advantage of positioning accuracy;
3) the utility model device is practical, safe and reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is top view of the present utility model;
Fig. 3 is side view of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1-Figure 3, a kind of lithographic press pneumatic power positioner, described lithographic press comprises printer table 1, described pneumatic power positioner is installed on the printer table 1 printed sheet material is positioned, described pneumatic power positioner comprises two pilot pins 2, two cylinders 3, control valve 4, tracheae 5 and switch 7, a described end pilot pin 2 is connected with cylinder 3, the other end is connected with printed sheet material, described cylinder 3 is connected with control valve 4 by tracheae 5, described switch 7 is connected with control valve 4 by electric wire 6, and described control valve 4 is arranged on the printer table 1.Described printed sheet material is provided with locating hole, and described pilot pin 2 is connected with printed sheet material by this locating hole.
The operation principle of above-mentioned lithographic press pneumatic power positioner is as follows: under open state, pilot pin 2 exceeds the about 2-4 millimeter in plane of printer table 1, printed sheet material is enclosed within (printed sheet material is in advance according to the made locating hole of size) on two pilot pins, open switch 7, control valve 4 control cylinders 2 hold printed sheet material, printed sheet material is fixed on the printer table 1, pilot pin 2 is return simultaneously, be lower than workbench 0.5-1 millimeter (when avoiding printing and web plate scraper run into), the web plate fixed mount moves down, and scraper begins on the net working in reciprocating mode once.Then, the web plate fixed mount is up mobile, and control valve 4 is closed, and pilot pin 2 rises, and beginning is working cycles for the second time.
