Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a pedestal used in a label thermal transfer device such as a thermal transfer press or a hand press.

(Prior art) Heat transfer labels can be patterned more easily and inexpensively than various conventional dyeing methods, and in recent years have been able to form multicolored and fine patterns, and these patterns have improved in terms of fastness and elasticity. However, it is sufficiently durable for practical use. For this reason, thermal transfer labels are used not only as trademark marks and quality marks for general clothing, but also for decoration of various sporting goods. This type of thermal transfer label is transferred to a predetermined position on clothing using a thermal transfer press or a hand press at a constant temperature and pressure.
During this transfer, in a hand press machine, the upper and lower irons are in full contact with each other, and in a thermal transfer press, the pedestal part of the lower iron is in full contact with the upper iron.

(Problem that the invention aims to solve) When pressing thermal transfer labels, if the upper and lower trowels are in full contact with each other as in a hand press machine, pressure may be applied to areas other than the necessary parts of the transferred article such as clothing. When heated, pressing marks or trowel marks may remain on the clothing after transfer, and the clothing is likely to be damaged by the heat. On the other hand, with thermal transfer press machines, the only part that comes into contact with the upper iron is the holder of the lower iron, so there is less heat damage to clothing than with hand press machines, but even if the iron marks are small, they still clearly remain. Put it away.

(Means for solving the problem) This invention improves the problem that press marks and trowel marks are produced on the transferred article such as clothing when a heat transfer label is crimped using a label heat transfer press machine or a hand press machine. The purpose of the present invention is to provide a pedestal in which pressing marks and trowel marks are less noticeable than in the past, and thermal damage to the transferred article is also less.

As illustrated in FIG. 1, the pedestal 2 according to this invention is attached to the surface of a fixed lower iron 6 in a label thermal transfer device such as a thermal transfer press 4 or a hand press. The pedestal 2 is made of a heat-resistant elastic plate that can be cut at room temperature, and the elastic plate has a thickness of, for example, 5 to 5.
It is an 8mm silicone rubber plate. For example, an 8 mm thick elastic plate is preferably used when the space to be transferred is narrow or when there are rubber, stitches, pockets, etc. around the garment to be transferred. Furthermore, a 5 mm thick elastic board is preferably used when the label transfer design is delicate. An aluminum frame 8 is usually fitted to this elastic plate as shown in FIG. 2, but if the transferred design is large, the aluminum frame may not be used.

As shown in FIG. 3, the elastic plate in the pedestal 2 has only a portion protruding that approximately corresponds to the design portion of the thermal transfer label to be used, and the peripheral wall 12 of this protruding portion 10 is tilted downward and outward. ing. The upper surface of the pedestal 2 is covered with a release sheet 14 made of polyfluoroethylene fiber such as Teflon (trade name).
This sheet 14 prevents even thin clothes from remaining on the elastic plate, improving the releasability after transfer.

(Function) The pedestal 2 of this invention is attached to the surface of the fixed lower iron 6, and the clothes 15 are placed on the lower iron 6 as shown in FIG.
After arranging the transfer target article, such as the above, the thermal transfer label 16 is placed face down so as to match the protrusion 10 of the pedestal 2. In the case of the thermal transfer press 4 of FIG. 1, such matching requires only one adjustment of the position of the label support frame 17. When the movable upper trowel 18 descends to press, only the design portion of the heat transfer label 16 is bonded by heat and pressure, so that the press marks and trowel marks on the garment 15 during transfer are not noticeable, and the garment is less likely to be damaged by heat. . Peripheral wall 12 of protrusion 10
However, if it is tilted downward and outward all around the circumference, it is possible to prevent pressure from escaping around the protrusion during pressing, so that the strength of transfer to the garment 15 is not reduced.

(Example) In order to create the pedestal 2 of this invention, a flat rectangular silicone rubber plate 20 with a thickness of 5 to 8 mm was used as a heat-resistant elastic plate that can be cut at room temperature, as shown in Fig. 2. An aluminum frame 8 is usually fitted to the rubber plate. The aluminum frame 8 has a shallow box shape with an opening on the top surface,
The vertical and horizontal internal dimensions are approximately equal to the external dimensions of the rubber plate 20. When the rubber plate 20 is horizontally fitted into the aluminum frame 8, it is necessary that only a portion corresponding to the height of the protrusion 10 protrudes from the upper side of the aluminum frame 8. On the other hand, take out one heat transfer label to be used and cut off 2 to 3 mm outside the design part of the label with scissors or a cutter knife. The cut-out label piece is turned over, placed in the center of the rubber plate 20, and then marked with a hit 22 using a writing instrument such as a ballpoint pen. Next, on the rubber plate surface, hit 2 parts other than the design part 24.
Cut along the lines 2 to the top of the aluminum frame 8 with a cutter,
At this time, the periphery of the design portion is inclined downward and outward, and the design portion 24 that remains uncut corresponds to the protrusion 10. The height of the protruding portion 10 is determined when the space to be transferred is narrow or when the garment 15 to be transferred is
Set it higher if there is rubber, stitches, pockets, etc. around the label, or lower it if the label has a delicate transfer design. If desired, the upper surface of the pedestal 2 is completely covered with a release sheet 14 such as Teflon (trade name), and the sheet is attached to the outer wall of the aluminum frame 8 with the retaining plate 2.
6 and 26 (see FIG. 3), and the retaining plate is fixed to the aluminum frame 8 with screws 27.

As shown in FIG. 1, the thermal transfer press 4 on which the pedestal 2 is installed has a vertically long rectangular parallelepiped shape, and for example, a cover 29 on the left side covers the operating mechanism of the transfer arm 28.
Attach. As shown in FIG.
and a safety guard 30, which has a hollow cylindrical shape and is disposed vertically fitted onto the upper iron 18. The lower part of the thermal transfer press machine 4 is
It is recessed from the front toward the rear, and a guard receiving plate 32 is horizontally disposed above the fixed lower iron 6 and the iron in this recessed portion. The surface of the lower iron 6 is flat, and after pasting the double-sided adhesive tape 34 on the back side of the pedestal 2 as shown in FIG. Bye. Also, in the case of a hand press machine, double-sided adhesive tape is pasted on the back of the pedestal and directly adhered to the lower trowel surface. On the other hand, the guard receiving plate 32 is attached to the inner wall of the apparatus by a hinge 36 and has an outer size large enough to be able to come into contact with the guard 30 (see FIG. 4). A rectangular opening 38 is provided in the center of the receiving plate 32, and the opening has a larger area than the horizontal surface of the lower iron 6.

In the thermal transfer press 4, the front panel 40 generally includes a display screen for press time and press temperature of the upper iron 18, a setting switch, a pressure gauge display panel,
Install air pressure adjustment valves, power switches, etc. The label support frame 17 is, for example, the front panel 4.
A lower opening (not shown) is formed by parallel plates 42, 42 disposed below 0 and spaced apart from each other by a predetermined distance so that a large number of stacked label stacks 44 can be taken out from below. Parallel plates 42, 42 can each be moved along a plate mounting plate 46 such that both plates 42 are positioned vertically opposite each other. Each plate 42 has a lower end bent inward to support a large number of label stacks 44, and an upper end bent outward to attach two bar stops to each plate so as to be movable in the front and back direction. I can do it. The horizontal bent portions of the vertical bars are connected to the stops, respectively, and the label stack 44 is held by the lower portions of the four bars. The transfer arm 28 has a horizontal part located below the front panel 40 when not in operation, and the front part of the horizontal part is bent at a right angle so that a truncated conical pad (not shown) faces upward at the distal end surface. Fixed horizontally. This pad is attached to the support frame 17 when not in operation.
It is close to the lower end surface of the label laminate 44 inside.
The transfer arm 28 is moved by a vertically installed pneumatic cylinder 48, during which the pad is rotated forward by a half turn and brought into close proximity to the pedestal 2. Thermal transfer press machine 4 is used to adsorb the label with the pad at the end of the arm.
A compressor (not shown) is installed outside the
The compressor drives a known vacuum generator (not shown). The vacuum generator communicates with the pad via transfer arm 28 to create a reduced pressure condition on the pad. The compressor mentioned above is
In addition to the drive cylinder 48 of the transfer arm 28, the upper trowel 18 and the safety card 30 are also plumbed to drive cylinders (not shown), respectively.

Before driving the entire thermal transfer press 4, the fifth
As shown in the figure, the guard receiving plate 32 is rotated upward to place the transferred article such as the clothing 15 on the lower iron 6, and then the receiving plate is returned to the horizontal position. Turn on the power switch and transfer switch, and when the predetermined temperature is reached, operation is possible. With the transfer arm 28 in the position of FIG. 1 and the safety guard 30 stationary above, depressing the foot pedal starts the vacuum generator. When the pad attracts the label 16 by starting the vacuum generator, the transfer arm 28 is started. When the transfer arm 28 rotates half a turn and reaches the lower end position, the label 16 is released from the pad and the transfer arm 28 returns to its original position. As the piston of the cylinder 48 rises, the safety guard 30 starts, and when the safety guard reaches the lower end position, the upper iron 18
start. When the upper iron 18 is lowered to the press position, a timer is started. After the predetermined pressing time has elapsed, the timer expires and the upper iron 18 and safety guard 30 are raised.

(Effect of the invention) When the pedestal according to this invention is attached to the fixed lower trowel surface of the thermal transfer device, after placing the transferred article on the lower trowel, the thermal transfer label is turned face down and the protruding part of the pedestal is By simply placing the label so that it matches the label, when the movable upper iron descends and presses, only the design part of the heat transfer label is pressed, making it less noticeable and preventing heat damage to the clothing. There are also few. In the pedestal of this invention, the peripheral wall of the protrusion is tilted downward and outward over the entire circumference, which prevents pressure from escaping around the protrusion during pressing, reducing the strength of transfer to clothing. There isn't. Furthermore, it is preferable to cover the top surface of the pedestal with a release sheet, since this prevents even thin clothing from remaining on the elastic plate and improves release properties after transfer.
