As described above, the printing apparatus used in manufacturing the conventional liquid bag has used a printing method in which a printing film is pressed with a tensile plate embossed with a predetermined letter or figure, as if a picture is taken. However, in such a conventional printing method, it is impossible to print very small letters or multicolor colors, and it is inconvenient to replace the tensile plate every time the contents to be printed are changed. If the height or the horizontal of the tensile plate is not precisely adjusted, There is a fear that leakage of liquid may occur due to the pressure of the plate resulting in the penetration of the sheet for producing a liquid bag.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a method of manufacturing a liquid bag which is capable of clearly printing very small letters or multicolor colors on the surface of a synthetic resin sheet for producing a liquid bag, And to provide a roll printing apparatus for a liquid bag which is free from the risk of puncturing failure.

The roll printing apparatus for a liquid bag according to the present invention comprises: a frame provided with a means for continuously feeding synthetic resin sheets (S) for producing a liquid bag; A first reel shaft supported on the frame so as to mount a rolled film F; A pair of guide rollers for switching the traveling direction of the transfer film F supplied from the first reel shaft to face the transfer film F at a predetermined distance on the sheet S; A transfer roller which reciprocates between the guide rollers and presses the upper surface of the transfer film F to transfer the contents printed on the transfer film F to the sheet S; A pair of conveying rollers for repeatedly conveying the transfer film F one pitch at a time while being rotated in close contact with each other; A second reel that recovers and rewinds the transfer film (F) having passed through the transfer roller; And a control unit.

The transfer printing film F on which the content to be displayed on the liquid bag is printed is pressed by the transfer roller and transferred to the sheet S so that a very small letter or multicolor There is an inconvenience that the color can be printed clearly and further the tension plate must be replaced. In particular, there is no fear that the sheet is punctured due to the pressure of the tension plate.

2 is a perspective view of a roll printing apparatus for a liquid bag according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings. However, even if it is indispensable to carry out the present invention, a detailed description will be omitted for the constitution which can be easily carried out by the ordinary artisan or belonging to the known art. In FIG. 2 illustrating the present invention, each component is given its own name and reference numerals, irrespective of FIG. 1 exemplified in the prior art.

2, a frame 10, a first reel 20, a pair of guide rollers 30a and 30b, a transfer roller 40, a pair of conveying rollers 30a and 30b, Rollers 50a and 50b, and a second reel shaft 60. [

First, the frame 10 constitutes a basic skeleton of a conventional liquid bag manufacturing apparatus. The frame 10 is provided with a means for continuously supplying the synthetic resin sheet S for producing a liquid bag, at regular intervals. For example, as shown in FIG. 1, a sheet feeding unit 100 for continuously feeding two sheets of synthetic resin sheets S having a constant width, a sheet feeding unit 100 for repeatedly advancing the sheet S by a predetermined interval, And can be implemented by the transfer unit 300.

The sheet supply unit 110 includes a reel shaft 110 on which a reel on which the sheet S is wound is mounted and a reel 110 on which the sheet S fed from the reel is moved up and down Down roller 120 as shown in FIG. The sheet supply unit 300 includes a sheet suction bar 310 and a sheet support bar 320.

The sheet S is separated from the sheet S and only the sheet adsorption bar 310 is retracted when the sheet S is advanced backward for a predetermined period while adsorbing the upper surface of the sheet S. Therefore, the sheet S is repeatedly conveyed by the reciprocating distance of the sheet suction bar 31, and a work process of a pitch is performed according to the conveyance distance.

When the sheet suction bar 310 advances together with the sheet S, the up-down roller 120 rises by the distance that the sheet S is conveyed. When the sheet suction bar 310 is backward The up-down roller 120 is lowered by the length of the sheet S supplied from the reel to maintain the tension of the sheet S constant.

Next, the first reel 20 is supported on the frame 10 at one end thereof so as to mount a rolled-up transfer film F thereon. In the transfer film F, characters and graphics to be displayed on the receiver bag are printed, and an eye mark is displayed in the longitudinal direction. The transfer film (F) is freely supplied from the first reel (20).

The guide rollers 30a and 30b switch the direction of the transfer film F fed from the first reel 20 to face the sheet S, And are spaced apart by a predetermined distance so as to be parallel to each other. At this time, the distance between the guide rollers 30a and 30b corresponds to the size of the liquid bag, and corresponds to a printing operation of one pitch.

The transfer roller 40 reciprocates between both guide rollers 30a and 30b to press the upper surface of the transfer film F to transfer the contents printed on the transfer film F to the sheet S . It is preferable that a heating means, for example, a heat ray, for facilitating a transfer operation is built in the transfer roller 40.

On both sides of the supporting portion supporting the transfer roller 40, a lifting cylinder 41 for lifting the transfer roller 40 is provided. The transfer roller 40 and its supporting portion reciprocate along a moving rail 11 provided on the frame 10. [

The movement of the sheet S and the transfer film F is restricted when the transfer roller 40 moves between the guide rollers 30a and 30b and the transfer roller 40 is transferred And is brought into close contact with the upper surface of the film (F). When the transfer roller 40 stops to change directions at both ends, the lifting cylinder 41 lifts the transfer roller 40 slightly. At this time, the sheet S and the transfer film F move together at a pitch.

Any means known in the art may be used as the means for reciprocating the both side support portions supporting the transfer roller 40 along the movement rail 11, but it is also possible to use, for example, a ball screw actuator . In FIG. 2, reference numeral 42 is a "cable" for protecting the electric wire and the pneumatic hose.

The transfer rollers 50a and 50b are brought into close contact with each other to rotate the transfer rollers 50a and 50b in opposite directions to advance the transfer film F inserted therebetween by a predetermined distance. That is, the eye mark sensor 51 is provided at the lower end of the conveying rollers 50a and 50b, and the eye mark sensor 51 is provided on the transfer film F in an eye- mark and controls the rotation of the driving roller 50a so that the transfer film F advances by a predetermined distance. At this time, the transfer distance of the transfer film F corresponding to one pitch is equal to the distance between the guide rollers 30a and 30b.

The conveying rollers 50a and 50b are constituted by a first conveying roller 50a driven by a servo motor 52 and a second conveying roller 50b brought into close contact with the first conveying roller 50a in a free state And the transfer film F is sandwiched between the first conveying roller 50a and the second conveying roller 50b.

Finally, the second reel shaft 60 recovers and rewinds the transfer film F passing through the driving roller 50 in the direction opposite to the first reel shaft 20. The second reel (60) is driven by a drive motor (61).

The roll printing apparatus of the present invention may further include a pitch sensor 70 for measuring the distance of the transfer film F supplied from the first reel 20. As shown in FIG. 2, the pitch sensor 70 is provided with a sensing roller that contacts the outer surface of the transfer film F mounted on the first reel 20. Therefore, the pitch sensor 70 functions to check and confirm the transfer distance of the transfer film F measured by the eye mark sensor 51. [ If the transfer distance of the transfer film F is not constant, printing failure occurs.
