The present invention is a gold foil printing apparatus driven by a roll, more specifically, a gold foil coated on a roll continuously rotated when printing by rotating the film coated with gold foil in close contact with the object to be printed by a roll having a mold heated to a set temperature. By controlling the supply of the film intermittently, the present invention relates to a gold foil printing apparatus driven by a roll, which prevents waste of the gold foil film and enables the selective use of gold foil films of various colors.

In general, as one of the means for improving the identification of the print content, the gold foil printing technique for expressing characters or figures with gold foil is widely used, and various kinds of printing apparatuses are used according to the object for gold foil printing. .

The conventional gold foil printing apparatus is composed of a press having a printing mold positioned on a vertical portion of a substrate on which a printed matter is placed and a printed object (hereinafter referred to as a "printed material"), and placed through the space between the printed material and the mold. In this paused state, as the press descends, a printing mold provided on the bottom surface of the printed material thermally compresses the gold foil film to produce the gold foil printing. However, the apparatus for printing while the printing mold is lifted by the press driving has a problem that the printing operation is very unsuitable and structurally complicated for a relatively long printed matter or a relatively large print area.

On the other hand, in view of the problem of the gold foil printing apparatus by the press drive, a device in which a printing mold is laid on the rotary roll has appeared, but in the case of this rotary roll type printing apparatus, the gold foil film is proportional to the rotation distance of the roll. As a result of passing the part not used for printing in the process of supplying continuously, there was a problem that the expensive gold foil film is wasted unnecessary.

The present invention was devised in view of the problems caused by the loss of the gold foil film generated during the gold foil printing process, and its purpose is to print gold foil by roll driving, which can recover only the waste gold foil portion on which the printing is made by a simple structure control device. To provide a device.

The present invention for achieving the above object, the printing roll is provided with a plurality of printing dies radially provided in the passage through which the printing object placed on the substrate and the support roll rotated in engagement with the upper and lower so as to be provided with appropriate intervals for the printing In a device in which the gold foil film passing between the roll and the support roll is printed on the surface of the printed material by heating and pressing, the tension roll for supplying the wound gold foil film is provided on one side of the printing roll. On the opposite side of the tension roll, a winding roll for recovering the gold foil film used for printing by the pulling force of the driving roll is installed, and a printing mold is disposed at the tip of the shaft provided in the printing roll to recognize the printing moment. A working plate having a matching protrusion is bonded to control the recovery operation of the gold foil film used for printing on the outer circumferential surface of the working plate. A flat swinging link is installed at the end of the link, and an operating tool swinging to offset the tension of the elastic spring is installed at the end of the hinge shaft, and the operating tool closely adheres to the driving roll driven to wind the gold foil film onto the winding roll. Alternatively, the touch roll is installed to control the gold foil film to be intermittently moved or stopped so that printing is performed by a printing mold arranged at a predetermined interval on the outer circumferential surface of the printing roll. As long as the gold foil film is characterized in that the recovery.

Hereinafter, the gold foil printing apparatus by the roll drive of the present invention will be described with reference to the accompanying drawings.

1 and 2 are a perspective view and a front configuration diagram showing the gold foil printing apparatus of the present invention, Figures 3a and 3b is a schematic view showing a part before and after the gold foil film supply of the gold foil printing apparatus, Figure 4 Figure 5a and 5b is a plan view showing the gold foil film used for printing by the present invention and the printing roll of the gold foil printing apparatus and its working plate.

Gold foil printing apparatus of the present invention is a printing roll 20 provided with a plurality of printing molds (M) radially provided in the passage through which the printing object (P) placed on the substrate 10 and the support roll 30 is rotated in engagement with this The printing roll 20 is provided up and down so that the appropriate interval is provided, and the printing roll 20 heat-presses the gold foil film F passing between the support rolls 30 to the surface of the printed matter.

In order to supply the gold foil film (F) wound in the form of a roll on one side of the printing roll 20, a tension roll (40) for drawing the gold foil film is installed when a traction force or more is applied, and the opposite side of the tension roll is printed Winding roll 41 is used to recover the waste gold foil film (F) used in the winding roll 41 is to wind the gold foil film by the traction force of the drive roll 50 to be described later.

A working plate 22 having a protrusion 23 corresponding to a portion where the printing mold M is disposed is joined to the front end portion of the shaft 21 provided in the printing roll 20 so as to recognize the printing moment. The outer circumferential surface of the operating plate is provided with a link 60 which swings horizontally to control the recovery operation of the gold foil film used for printing.

One end of the link 60 is provided with an operating hole 61 swinging to offset the tension of the elastic spring 63 starting from the hinge shaft 62, the operation port 61 is rolled with gold foil film A touch roll 70 is installed to control the gold foil film to be intermittently moved or stopped while being in close contact with or separated from the driving roll 50 so as to be pulled to the 41.

It is preferable to equally adjust the protruding positions of the plurality of protrusions 23 provided on the working plate 22 of the same axis with respect to the plurality of printing molds M radially laid on the outer circumferential surface of the printing roll 20.

That is, by forming the arc of the printing mold M formed on the printing roll 20 and the arc of the protrusion 23 provided on the operating plate 22 to be the same or slightly enlarged, the printing mold prints the gold foil film F. While the gold foil printing is performed by heat pressing on (P), the protrusion 23 of the operating plate 23 displaces the link 60 circumscribed thereto, and starts the hinge shaft 62 by the displacement operation of the link. By interlocking the operating port 61 under the tension of the elastic spring 63, the touch roll 70 installed thereon is in close contact with the adjacent driving roll 50, the gold foil film is sandwiched.

At the moment when the touch roll 70 is in close contact with the driving roll 50, the rotational force of the driving roll 50 is applied to the traction force through the gold foil film passing therebetween, so that the tension rolls are in balance with each other through the gold foil film. Of the 40 and the winding roll 41 is to take out the gold foil film wound on the tension roll, so as to be wound on the winding roll only as much as a small amount of bag in the portion used for printing (see Fig. 3b).

Meanwhile, as shown in FIG. 3A, when the link 60 circumscribed to the operation plate 22 is positioned at the groove portion away from the protrusion 23 section, the operation interval 61 connected to the link 60 is an elastic spring 63. Since the touch roll 70, which is in close contact with the driving roll 50, is pulled out, the pulling operation of the gold foil film by the driving roll 50 is stopped.

Even when the touch roll 70 is separated from the driving roll 50 and the traction operation of the gold foil film is stopped, the rotation operation of the driving roll 50 is maintained but no load is not applied to the gold foil film. The driving force is applied to the tension roll 40 and the winding roll 41 to which the driving force is applied in mutually opposite directions through the film, and the progress or withdrawal of the gold foil film is stopped.

Therefore, the gold foil film is supplied in an intermittent operation for recovering the waste gold foil film only at a moment in which the gold foil printing is made, or at a margin which is slightly larger than the printing range. As compared to the example of the present invention it can prevent the waste of the gold foil film.

Figures 6a, 6b and 7a, 7b shows another embodiment of the present invention, the operation plate 22 installed on the same axis of the printing roll 20 and the link thereon as a means for controlling the supply of the gold foil film from above Although the mechanical motion of the touch roll 70 connected by 60 has been described, the operation plate 22 bonded on the same axis is rotated to recognize the printing moment by the printing roll 20. A sensor having an eccentric cam 91 is installed to swing a detection sensor 80 capable of measuring a range, wherein the detection sensor swings an operation 61 provided with a touch roll 70 in close contact with the driving roll 50. 90, it is also possible to control the supply of the gold foil film electronically by the sensor.

The gold foil printing apparatus by the roll drive according to the present invention supplies the gold foil film by the intermittent operation to recover the waste gold foil film at a margin which is a little more than the range used for printing or printing range only at the moment when the gold foil printing is performed. By doing so, there is an economic effect that can prevent the waste of expensive gold foil film.
