Description

[0001] Fabric unwinder device and transfer machine having the same [

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a roll fabric unwinding mechanism of a new concept capable of easily and easily mounting a roll fabric, and a transfer machine having the roll fabric unwinding mechanism.

Generally, various kinds of fabrics such as handkerchiefs and cloths are printed by the transfer printing method.

In such a transfer printing method, a transfer sheet coated with a specific pattern and a photograph is placed on a fabric (fiber) to be printed, and then the transfer sheet and the fabric (fiber) are pressed tightly with a heating roller heated to an appropriate temperature. And the pattern on the transfer sheet is transferred to the fabric (fiber) while moving.

The fabric is fed in a state that the fabric is wound around a paper tube. The fabric is hooked on the paper tube so that both ends of the shaft are inserted into the paper tube while passing through the shaft, and a separate fixing mechanism It is troublesome and inconvenient to work.

Meanwhile, in the conventional transferring machine, it is necessary to preheat the heating roller sufficiently in advance for a smooth transfer operation. When the heating roller is sufficiently preheated to a suitable temperature for the operation, the transferring paper and the fabric are supplied in a laminated form.

However, when the heating roller is fed to the heating roller in the excited state, the transfer operation is finely distorted or the transfer operation is performed in a severely curled or wrinkled state And thus the transfer quality is very low during the transferring operation, and there is a serious problem that the defective product is mass-produced.

The operation of the transducer according to the present invention having the above-described structure will be described as follows.

First, a transfer transfer paper drum D2 in which a transfer paper P is wound is disposed on the first body 11, and a roll fabric RF is placed in a roll fabric take-up mechanism 100 provided in the first body 11, I will.

More specifically, the idler 120 arranged in an arc shape constituting the roll fabric unwinding mechanism 100 places the roll fabric RF inward, and then both ends of the roll fabric RF are supported by the support unit (RF) is prevented from flowing (moving) along the longitudinal direction of the idler 120 by using the rollers 130.

The transfer paper P and the fabric F are wound on the winding paper D3 and the winding drum D4 via the thermal transfer unit 20, respectively.

The fabric D is wound while the winding drum D4 is rotated by the second driving means 60 so that the fabric F of the roll fabric RF held in the roll fabric unwinding mechanism 100 ) Is released.

The transfer paper P and the fabric F are transferred while being interposed between the heating drum 21 and the belt 22c of the thermal transfer unit 20 and then discharged and discharged to the above- (D3) and the winding drum (D4), respectively.

FIG. 5 is a side view showing another embodiment of a transfer device equipped with a roll material unwinding mechanism according to the present invention, and FIGS. 6 and 7 are partially enlarged views for explaining the action of the transfer device shown in FIG.

On the other hand, the transferring unit preheats the heating drum 21 of the thermal transfer unit 20 sufficiently in advance for a smooth transfer operation, and then, when the heating drum 21 of the thermal transfer unit 20 is sufficiently preheated to a temperature suitable for the operation The transfer paper P and the fabric F are supplied in a laminated form.

However, in the case of the transfer device of the above embodiment, the transfer paper P and the fabric F are excited by the heat generated from the heating drum 21, and when the transfer paper P and the fabric F are supplied to the thermal transfer unit 20 in this excited state, The transfer operation is performed in a state where the transfer operation is performed in a severe state or in a curled state or a wrinkled state and thus there is a serious problem that the transfer quality is very low during the transfer operation and the defective product is mass-produced.

Note that in this embodiment, the guide plate 80 is provided at the upper portion of the work table 13 to solve the above problems.

5 to 7, the guide plate 80 is a member having a predetermined width and thickness. In the present embodiment, the guide plate 80 is installed on the work table 13 on which the fabric F and the transfer paper P are moved The preheating effect (shortening of time) is raised before the transferring operation and the function of preventing the entrance of the transferring paper P into the thermal transfer unit 20 while the fabric F and the transfer paper P are excited during the transferring operation is prevented.

The guide plate 80 is disposed adjacent to the heating drum 21 of the thermal transfer unit 20 so as to be spaced apart from the upper surface of the work table 13 and is disposed in a direction crossing the longitudinal direction of the work table 13, That is, in the width direction of the work table 13.

6) is formed on the guide plate 80 so as to penetrate the bolt (see FIG. 6), and the upper surface of the work table 13 and the guide plate 80 ) Can be easily adjusted.

For example, in order to perform a smooth transfer operation, the heating drum 21 of the thermal transfer unit 20 is driven to perform preheating.

More specifically, as the heating drum 21 is gradually preheated, the heat of the heating drum 21 is diverted to the surroundings, and the divergent heat spreads to the surrounding area, so that the workbench 13 is naturally preheated , And the heat that has passed through the work table (13) passes through the guide plate (80).

That is, as the heat of the heating drum 21 passes over the guide plate 80, the work table 13 disposed at the lower portion of the guide plate 80 can be quickly heated by the guide plate 80 There is an advantage that the preheating time can be shortened.

When the heating drum 21 and the work table 13 are sufficiently preheated as described above, the transfer sheet P and the cloth F are supplied in a laminated form to proceed the transferring operation. At this time, The transfer paper (P) and the fabric (F) are excited by the radiating heat.

The transfer sheet P and the cloth F are passed between the work table 13 and the guide plate 80 to be supplied to the thermal transfer unit 20 in a state in which the transfer sheet P and the cloth F are excited It is possible to solve the problem that the transfer operation is performed in a slightly distorted state and that the transfer operation is performed in a curled state or a wrinkled state, so that defective products can be significantly lowered and the transfer quality can be improved There is an advantage.

Therefore, according to the present embodiment, the guide plate 80 is provided on the upper portion of the work table 13 to shorten the preheating time of the work table 13. In addition, the transfer sheet P and the fabric F It is possible to expect the effect of the one stone two bird which can be prevented from being supplied to the thermal transfer unit 20 in advance and maximize the transfer quality.

The operation of the present invention constructed as described above will be described.

The transfer sheet P is fed from the supply transfer drum D2 and the fabric F is fed from the roll fabric RF placed on the roll fabric unwinding mechanism 100, The transfer paper P and the fabric F supplied in this manner are transferred between the heating drum 21 and the belt 22c of the thermal transfer unit 20 while being transferred therebetween, And wound around a winding drum D3 and a winding drum D4.

When the transfer paper P and the fabric F are supplied to the thermal transfer unit 20 as described above, the transfer paper P and the fabric F are excited by the heat radiated from the heating drum 21, As the workbench 13 and the guide plate 80 hold the transfer paper P and the fabric F moving in the excited state as they are, the transfer paper P and the fabric F are stacked in the thermal transfer unit 20, which has the advantage of significantly lowering defective products and improving transfer quality.

8 is a plan view for explaining another embodiment of the transducer according to the present invention.

8) of the work table 13 can maintain a suitable preheat temperature with a relatively small amount of contact with the outside air, but it is preferable that the both side edges A ' 8) is not suitable for the preheating temperature due to continuous contact (heat exchange) with ambient air.

8, the guide plate 80 is installed in the width direction of the work table 13, and guide plates 80 having a predetermined size are attached to the edge of the work table 13, respectively, as shown in Fig. 8 Note that the temperature compensation was performed close to the temperature in the middle (A: see FIG. 8).

If the guide plate 80 is installed at the edge of the work table 13 as described above, the temperature of the edge of the work table 13 can be made higher than the temperature in the middle of the work table 13 (see A in FIG. 8) .

Accordingly, the heat loss due to the continuous contact (heat exchange) with the outside air can be compensated for at the side edges A '(see FIG. 8), so that the preheating temperature can be uniformly maintained throughout the work table 13, There is an advantage that the transfer of the edge of the fabric can be smoothly performed during the operation.

The guide plate 80 may further include an inclined portion 81 which is inclined upwards in a direction opposite to the direction in which the fabric F and the transfer paper P are moved.

For example, if a flat guide plate 80 is installed on the top of the work table 13, the fabric F and the transfer sheet P pass between the guide plate 80 and the work table 13 There is a problem in that the distance between the guide plate 80 and the work table 13 must be excessively spaced.

However, if the inclined portion 81 is reinforced by the guide plate 80 as described above, the fabric F and the transfer paper P can be easily guided between the guide plate 80 and the workbench 13, The distance between the guide plate 80 and the work table 13 can be minimized so that the fabric F and the transfer sheet P can be separated from each other It is possible to suppress the movement to the excited state as much as possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
