Abstract

PROBLEM TO BE SOLVED: To provide a hot pressing machine capable of stably hot pressing marks on a hot pressed material in a simple structure and with a simple operation. SOLUTION: In this hot pressing machine 10, a pressing part 30 having a contact surface formed in a prescribed area generates heat at a predetermined temperature and loads a fixed pressure. A base part 26 is installed on the pressing side of the pressing part 30. Plural base parts 26 are formed in a shape having an area almost equal to a prescribed area of the pressing area 30 or a smaller area than the prescribed area. Thus, hot pressing is carried out by nippingly inserting a mark and a fabric between the pressing part 30 and the base part 26 and bringing the pressing part 30 to give a pressure with heating. The base parts 26 have plural different contact areas, so the pressure is arbitrary selected by changing the base part. Thus, an exclusive hot pressing circumstance suitable for the mark and the fabric is constituted by solely changing the base part 26.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot press machine, and more particularly to a hot press machine for pressing a mark such as a short fiber implant or an emblem on an object to be heated such as a uniform or a shirt formed with at least fibers. Heat press machine.

[0002]

2. Description of the Related Art It is a common practice to attach a mark such as a number or a symbol to clothing such as a shirt or a uniform for the purpose of presenting a department or a team to which the user belongs. In order to easily attach the mark to clothing, a thermocompression type mark or a thermal transfer type mark which can be attached to clothing by heating and pressing is known. For example, a mark can be placed on clothing, and the mark and clothing can be attached by applying pressure while heating with a heating device such as an iron.

[0003] Usually, a hot-melt adhesive (so-called hot melt adhesive) is applied to the clothing side of the mark, and the adhesive melts under a predetermined temperature environment and a predetermined pressure is applied to the mark. The addition allows the adhesive to penetrate into the garment to integrate the mark and the garment.

[0004] However, in order to melt the adhesive uniformly or to infiltrate the clothing evenly, there is a heating and pressing environment of an optimum temperature and an optimum pressure when performing heating and pressing. Because the melting of the agent is uneven or the penetration into the clothes is uneven,
Insufficient heating pressure causes easy peeling.

[0005] Therefore, a heat press machine for automatically adjusting a heating and pressing environment of an optimum temperature and an optimum pressure for heating and pressing the mark and heating and pressing the mark on the garment, and a heating machine according to the input temperature and pressure are provided. 2. Description of the Related Art There has been known a heat press machine that builds a pressing environment and heats and presses a mark on clothing.

[0006]

However, the conventional heat press machine has a uniform pressure environment according to the mark and the clothing in order to obtain a heating and pressing environment of an optimum temperature and an optimum pressure for heating and pressing the mark. So the heat press must be adjusted. That is, a plurality of uniform pressure environments must be constructed in accordance with the types of marks and clothing, and each time a pressure setting and a structure capable of finely adjusting the pressure are required. Therefore, the structure of the heat press becomes complicated, and it is necessary to perform troublesome operations.

The present invention has been made in view of the above circumstances, and has as its object to provide a heat press machine capable of stably heating and pressing a mark on a material to be heated and pressed by a simple operation and a simple operation. .

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a heat press for heating and pressing a mark on an object to be heated and formed at least including fibers, wherein the heat is generated at a predetermined temperature. Pressurizing means formed with a predetermined area and applying a predetermined constant pressure to the pressure-applying member; and as the pressure-applying member, an area substantially equal to the predetermined area or an area smaller than the predetermined area. It is characterized by comprising a plurality of exchange base means formed with a pressurized side shape, and pedestal means configured to be able to attach any one of the exchange base means.

Further, the pedestal means has a rotating means for rotating the exchange base means.

In the heat press of the present invention, the pressurizing means generates heat at a predetermined temperature and applies a constant pressure to the pressure-applied member. The pressing means is formed with a predetermined area, and can apply a constant pressure within the predetermined area. The pressurizing means can apply pressure to the exchange base means attached to the pedestal means. The heat generated by the pressurizing means is transmitted to the exchange base means. There are a plurality of exchange base means, and each exchange base means is formed in a shape to be pressed by an area substantially equal to or smaller than a predetermined area of the pressing means. Therefore, the object to be heated and the mark are sandwiched between the pressurizing means and the exchange base means, and the pressurizing means presses the heating object toward the exchange base means while generating heat, thereby pressing the object to be heated and pressed. The mark can be heated and pressed.

When the pressure-applying member, that is, the area of contact between the exchange base means and the pressurizing means substantially coincides with each other, a constant pressure is applied substantially uniformly from the pressurizing means. When the area of the exchange base means is smaller than the area of the pressurizing means, the constant pressure applied from the pressurizing means concentrates on the small area,
The pressure applied to the exchange base means increases. Therefore, an arbitrary pressure can be selected only by exchanging a plurality of exchange base means. For this reason, if the area of the exchange base means that is in contact with the pressurizing means is set in advance in accordance with the desired pressure, only by exchanging the exchange base means, a dedicated heating and pressurizing environment corresponding to the mark and the clothing. Can be built.

Further, as described in claim 2, by providing the pedestal means with a rotating means for rotating the exchange base means, the pressure is increased by rotating the exchange base means having different vertical and horizontal lengths. Can be changed. That is, for example, when the exchange base means is configured with a rectangular area having one of the vertical and horizontal lengths smaller than the size of the pressurizing means, the vertical and horizontal lengths are reduced by rotating the exchange base means. Since they are different, the area where the pressurizing unit and the exchange base unit contact each other changes according to the rotation angle. Therefore, the pressure can be adjusted by one exchange base means.

A pressure time setting unit 18 is attached.

The pressing section 30 has a spring section 70. The spring portion 70 includes four springs 72 and is fixed to the upper surface of the pressing portion 30 and the plate 34, and is configured so that the plate 34 uniformly presses the base 26 at a constant pressure P. The pressurizing unit 30 includes a heat source 74,
The heat source 74 uniformly transfers heat to the plate 34. The pressurizing section 30 has an opening / closing lever 32. The opening / closing lever 32 is used to start or release pressurization by the spring portion 70. Further, the pressing unit 30 includes an arm 64, and the arm 64 forms a part of the opening / closing link unit 40.

The opening / closing link section 40 has a fixed base 46 fixed to the base 12. A shaft 51 is rotatably attached to the fixed base 46, and a relay plate is attached to the shaft 51. The arm 64 is fixed to the relay plate 50, and the rotation of the relay plate 50 causes the pressing unit 30 to pivot. Note that a stopper 48 is fixed to the fixed base 46 to limit the rotation of the relay plate 50. A shaft 52 is rotatably attached to the fixed base 46, and one end of an arm 62 is attached to the shaft 52. The other end of the arm 62 is the pressure lever 2
One end of 8 (the side opposite to the grip side) is fixed. A shaft 56 is rotatably mounted near the end of the arm 62, and one side of a cam 58 to which the abutment 60 is fixed is rotatably mounted on the shaft 56.

A shaft 54 is rotatably mounted near the middle abdomen of the arm 64.
, The other side of the cam 58 is rotatably mounted. The fixed base 46, the relay plate 50, the cam 58, the arms 62, 64, which are connected by these shafts 51 to 56,
This constitutes a link mechanism. Note that the arm 64
The other end of the spring 42 to which one end of the base 12 is fixed and the other end of the spring 44 to which one end is fixed to a fixed base 46 are fixed to one end (the side opposite to the pressing portion 30).

Therefore, by turning the pressing lever 28, the pressing portion 30 moves in the pressing direction toward the base portion 26 (from the open state of FIGS. 1 and 3 to the closed state of FIGS. 2 and 4). ) Or pressing in the opposite direction. When heating and pressing, the power is turned on, the temperature is adjusted (set) at the time of heating and pressing by the temperature adjusting unit 16, and the pressing time is set by the pressing time setting unit 18. Next, as shown in FIG.
And the mark 80 are placed in order. And pressurizing lever 2

After this pressure contact, the plate 34 is heated to the temperature controlled by the temperature control unit 16 for the pressurization time by the pressurization time setting unit 18 (by a timer). In this way, the base 26
When the plate 34 is pressed and pressed and heated, a hot pressing press can be performed.

As is well known, the mark 80 has a hot-melt adhesive applied to the back surface of the base cloth. The hot-melt adhesive has a predetermined temperature (for example, 15 degrees Celsius).
(0 degree). Therefore, when the clothing 82 and the mark 80 are placed on the base portion 26 in order and the plate 34 is pressed against the base portion 26, the plate 34 is heated to a predetermined temperature, so that the hot melt bonding is performed. The agent melts. Since the garment 82 and the mark 80 are pressurized by the pressurizing section by the plate 34, a part of the melted adhesive for hot melt permeates the garment 82 and is entangled with the fiber of the garment, so that the garment 82 and the mark 80 Will be integrated.

Here, the heat press 10 of the present embodiment
As shown in FIG. 5, a base 26 (so-called iron) is detachably fixed on the pedestal 24. The base 24 is the base 1
2 and the base portion 26, the cylindrical portion 24A
And an upper disk portion 23 and a lower disk portion 25,
The upper disk portion 23 and the lower disk portion 2 are provided at both ends of the cylindrical portion 24A.
5 is fixed. The lower disk portion 25 is fixed to the base 12. The upper disk portion 23 is provided with a protrusion 23A at a substantially central portion thereof. Further, the upper disk portion 23 is provided with two long holes 23B of a predetermined length along the circumference substantially symmetrically about the projection 23A.

The base portion 26 has a mounting portion 38 on a surface (back surface) opposite to the surface in contact with the plate 34.
The mounting portion 38 is formed in a quadrangular shape, and has a hole 38A at the center (the intersection of diagonal lines). This perforation 3
The mounting part 38 is fixed to the base 26 so that the position of 8A is the position of the center (or the center of gravity) of the base 26. The diameter of the perforation 38A is slightly larger than the outer shape of the projection 23A provided on the upper disk portion 23. The mounting portion 38 has a screw hole 3 for fixing the fixing screw 36.
8B is substantially symmetrical about the perforation 38A, and
It is provided in the place.

The mounting portion 3 attached to the base portion 26 is provided on a projection 23A provided on the upper disk portion 23 of the base 24.
8 and the fixing screws 36
Thus, the base 24 and the base 26 are fixed. This fixing is carried out by using a long hole 23 provided in the upper disc portion 23 of the base 24.
B allows the base 26 to be rotated. For this reason, the position of the base 26 can be finely adjusted and fixed, or set at an arbitrary angle and fixed.

As described above, the base 26 is detachable from the pedestal 24. Therefore, in the present embodiment, FIG.
As shown in (1), a plurality of base units 26 (here, four types) are prepared. FIG. 6A shows a first base 26 </ b> A as a standard base 26. This first base portion 26A
Has substantially the same contact area as the plate 34 of the pressurizing unit 30, and can press the first base 26 </ b> A at a constant pressure set by the pressurizing unit 30. 2nd base part 2
6B reduces the outer shape of the plate 3B.
4 and the contact area is smaller than the first base 26A. The state where the second base portion 26B is rotated by approximately 90 degrees with respect to the plate 34 of the pressing portion 30 is indicated by a dotted line (reference numeral 26B 'in FIG. 6).

The third base 26C has a smaller contact area with the plate 34 than the second base 26B, and the fourth base 26D has a smaller contact area with the plate 34 than the third base 26C.
Has been smaller. Thus, the first base 26A
The outer shapes of the fourth to fourth bases 26D are reduced in the order of the first base 26A, the second base 26B, the third base 26C, and the fourth base 26D, and the contact area with the plate 34 is reduced. Are reduced in order. Note that mounting portions 38 having the same shape and having perforations 38A are fixed to the back surfaces of the first to fourth base portions 26A to 26D.

As described above, the rotation of the pressure lever 28 causes the pressure portion 30 to be pressed against the base portion 26 to be heated and pressed. When the first base portion 26A is attached to the pedestal 24, Pressure is applied to the contact surface of the first base 26A.
That is, the pressure P is evenly applied from the pressurizing unit 30 set so as to be able to press with the constant pressure P over the contact surface of the first base 26A.

When the attachment to the pedestal 24 is changed from the first base portion 26A to the second base portion 26B (the state indicated by the solid line in FIG. 6B), the contact of the pressing portion 30 with the plate 34 is achieved. Since the area is small, the constant pressure P
Is concentrated on the second base portion 26B having a small area. Therefore, a pressure Pb (P <Pb) greater than the pressure P of the first base 26A is evenly applied to the second base 26B.

When the second base 26B is fixed at the rotated position (the state shown by the dotted line in FIG. 6B), the contact area of the pressing portion 30 with the plate 34 is further reduced. Therefore, a larger pressure Pb ′ (P <Pb <Pb ′) is evenly applied to the second base portion 26B.

Further, the contact area gradually decreases or increases during the rotation of the second base portion 26B. For this reason,
By fixing at an arbitrary position during rotation, the pressure Pb ″ applied to the second base portion 26B (when the state indicated by the dotted line in FIG. 6B is the minimum contact area, Pb ≦ Pb ″
≦ Pb ′).

Similarly, when the third base 26C is mounted on the pedestal 24, the contact area of the pressing portion 30 with the plate 34 is further reduced.
An even greater pressure Pc (P <Pb <Pc) is evenly applied. When the third base 26C is rotated and fixed, when the contact area is further reduced, a larger pressure Pc '(P <Pb <Pc <Pc') is evenly applied. Further, by fixing the third base 26C at an arbitrary position during the rotation, the third base 26C is fixed.
(When the rotated state is the minimum contact area, Pc ≦ Pc ″ ≦ Pc ′) can be adjusted.

Similarly, when the fourth base 26D is attached to the pedestal 24, the contact area of the pressurizing section 30 with the plate 34 is further reduced, so that a larger pressure Pc is applied to the fourth base 26D. (P <Pb <Pc <Pd) are equally provided. When the fourth base 26D is rotated and fixed, when the contact area is further reduced, a larger pressure Pc ′ (P <Pb <Pc <Pd <Pd ′) is evenly applied. Further, by fixing at an arbitrary position during the rotation of the fourth base 26D, the pressure Pd ″ applied to the fourth base 26D (when the rotated state is the minimum contact area, Pd ≦ Pd “≦ Pd ′) can also be adjusted.

As described above, in this embodiment, any one of a plurality of base portions having different shapes can be exchanged. Accordingly, even when the pressure unit 30 is configured to apply a constant pressure P, an arbitrary pressure application can be set only by replacing the base 26. Therefore, the mark 80 and the clothing 82
If the size of the base portion is determined for each pressure at the time of pressing required according to the type and the base portion is prepared in advance, if the pressure needs to be changed depending on the type of the mark 80 or the clothing 82, By attaching the corresponding base, the mark 8
Pressurization according to 0 or clothing 82 becomes possible. Therefore, the pressure can be easily adjusted only by replacing the base portion 26, and even when the pressure needs to be changed, the heating and pressing press can be easily performed without performing complicated adjustment and complicated setting. It can be carried out.

That is, when the plate 34 is pressed against the base 26 at the mark 80 on which the hot melt adhesive is applied, the plate 34 is heated to a predetermined temperature, so that the hot melt adhesive is applied. Melts. Since the garment 82 and the mark 80 are pressurized by the pressurizing section by the plate 34, a part of the melted adhesive for hot melt permeates the garment 82 and is entangled with the fiber of the garment, so that the garment 82 and the mark 80 Will be integrated.
At this time, the base portion is attached to the mark 80 and the clothing 82 so that the pressure according to the type is applied, and the heating and pressing is performed. Integrated (mark 8 on clothing 82)
0 is attached).

The base of the present embodiment is rotatable. For this reason, if the shape is different in length and width,
The contact area between the pressing unit and the base unit changes according to the rotation angle. This allows fine adjustment of the pressure. Also,
By fixing the base at an arbitrary position, it is possible to set an arbitrary pressure between the maximum contact area and the minimum contact area.

In this embodiment, the case where four base portions are used has been described. However, the present invention is not limited to this, and base portions having different contact areas, for example, two or more base portions are used. What is necessary is just to have a replaceable base part and at least one base part with different vertical and horizontal lengths. Further, in the present embodiment, the case where the square base portion is used has been described, but the present invention is not limited to the square shape, and may be any of a circular or elliptical shape, a polygonal shape, and an asymmetric shape. .

Further, the base portion is not limited to one, and may be configured by combining a plurality of base portions. For example, as shown in FIG. 8A, the fifth base 26E can be configured by combining a base 26Ea, a base 26Eb, and a base 26Ec. As shown in FIGS. 8B and 8C, the fifth base portion 26E has a hinge 39 on the back surface (the surface opposite to the heating press side). The base portion 26Ea and the base portion 26Eb are pivotably attached to the base portion 26Eb.
Eb and the base 26Ec are pivotably mounted.
The hinge 39 has a fixing function, and is heated and pressed at a position where substantially the same plane is formed by each of the base 26Ea, the base 26Eb, and the base 26Ec (FIGS. 8A and 8B). Is fixed as possible.

Therefore, in the fifth base 26E, the contact area (see FIG. 8B) formed on the substantially same plane by the base 26Ea, the base 26Eb, and the base 26Ec is:
It is formed only by the base portion 26Eb (FIG. 8C).
The contact area of only the base part 26Eb (turning the base parts 26Ea and 26Ec) and the base part 26Ea and the base part 26Eb
(Turn only the base 26Ec) or the base 26Eb
And a contact area formed by the base portion 26Ec (only the base portion 26Ea is swiveled), so that four types of contact areas can be formed. Thus, the pressure can be adjusted by the turning operation of at least one turnable base portion without replacing the base portion.

[0038]

As described above, according to the present invention, a plurality of exchange base means having different contact areas with the pressurizing means can be exchangeably mounted.
It is possible to select an arbitrary pressure only by exchanging, and it is possible to construct an exclusive heating and pressing environment corresponding to the mark and the clothing only by exchanging the exchange base means.
