BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fusing heat edge, and more particularly to a heating type cutting blade used for fusing a heat-melting sheet used for packaging clothes, etc. with a free line.

[0002]

2. Description of the Related Art Conventionally, in the cleaning industry,
When finally delivering clothes to be cleaned to a client, there is a service in which the clothes are hung on a simple hanger and wrapped with a synthetic resin sheet such as polypropylene.

In the step of covering the packaging sheet, a method as shown in FIG. 6 is adopted, and a large number of clothes after cleaning are efficiently processed into a delivered state. That is, the clothes 52 hung on the simple hanger 51 is suspended on a fixed hook 53 installed in advance, the tubular packaging sheet 54 is pulled down from the upper part, and the circumference of the clothes 52 is covered to the lower side of the body, In this state, the front and back sides of the wrapping sheet 54 are welded along the shoulder line of the garment 52, and at the same time, the wrapping sheet 54 is cut by a cut line 56 composed of a line near the upper side of the welding line 55 and a horizontal line.

Therefore, the wrapping sheet 54 on the side of the garment 52 after cutting is closed by the shoulder line of the garment 52 and covers the body and sleeves in a tubular shape, resulting in a compact and well-formed wrapping form. . Further, according to this step, the packaging sheet 54 can be freely cut according to the length of the clothes 52. The portion 57 surrounded by the cut line 56 is discarded as garbage, and the lower end of the packaging sheet 54 to be used next becomes horizontal because the portion 57 is removed,
The lower end can be used as it is in the next packaging process.

[0005]

By the way, as the above-mentioned welding device, a mold piece protruding along the welding line 55 is provided, and the packaging sheet 54 is heated in such a state that the packaging sheet 54 is melted. A method of sealing the front and back sheets with the welding line 55 by pressing the sheet to the receiving side opposite to each other is adopted, but the cutting device has a sharp cutting blade type provided along the cut line 56. With packaging sheet 54
The method of cutting is adopted.

Here, as the cutting device, it is conceivable to adopt a method of fusing along the cut line 56 by using a heating type cutting blade composed of a mold member, but the cut line 56 is a simple straight line. It is difficult to press and join the tip end with the seating side accurately because the line is not present and is considerably long, resulting in an incomplete cutting section. Further, when a mold member is used for the cutting blade, its heat capacity is large, so a large amount of electric power is required for heating, and the temperature control becomes very complicated.

On the other hand, in the cutting method using the sharp blade die, if the blade edge deteriorates due to repeated use, incomplete cutting occurs, but the shape of the blade die is not simple and the cutting is performed by the shearing mechanism. Therefore, the male and female blade dies have to be remanufactured, resulting in very high manufacturing and maintenance costs. In addition, recently, as the packaging sheet 54, the one with fibers on the back side sheet may be used,
When such a packaging sheet is sheared, defective cutting often occurs, and the blade mold is significantly deteriorated, which requires replacement in a short period of time.

[0008] Therefore, the present invention provides a fusing heat edge capable of fusing a heat-fusible sheet with a free line and easily controlling the temperature with a small amount of electric power. It was created for the purpose of eliminating the defects.

[0009]

Means for Solving the Problems The present invention is, between two strip-shaped <br/> flexible insulation film, a flexible metal plate and strip flexible with excellent strip thermally conductive Electrically insulating layer and strip-shaped flexible surface

[0010]

[Action] heat generated in flexible plane heater via a flexible electrically insulating layer conducting the flexible metal plate, heating the flexible metal plate. Further, since the flexible planar heater and the flexible metal plate are sandwiched between the two flexible heat insulating films, heat dissipation and conduction to the outside are suppressed, and the flexible metal Since the plate has a small heat capacity, it can be heated by only supplying a small amount of electric power to the flexible planar heater, and its temperature can be easily controlled.

Meanwhile, the components of the blowing for heat edge longitudinally strip der because having all flexible
It is possible to bend the surface freely, and the required fusing line
If it is installed along the mounting surface of the mold material that is formed corresponding to, the surface facing the installation surface of the melted material of other members and mold materials
The side end of the more flexible metal plate can be formed in a shape along a required fusing line. Further, since the flexible metal plate is held by the flexible flexible heat insulating film, the side end portion of the heated flexible metal plate is sealed.
When abutting against the seat side through a sheet-shaped melted object ,
The flexible heat insulating film flexes appropriately and acts as a cushioning member, and it is possible to absorb an error in accuracy between the tip of the flexible metal plate and the seat, and further, an excessive pressing force does not act. Therefore , deterioration of the flexible metal plate can be prevented.

Embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 5. 1 is a cross-sectional view (cross-sectional view taken along the line XX in FIG. 2) of a main portion of the fusing heat edge according to the embodiment.
Shows an overall plan view of the heat edge for fusing. Figure 1
As shown in Fig. 2, this heat-dissipating heat edge has a layered structure, and a planar heater composed of a film resistor with ceramic insulating sheets 2 and 3 on both sides of a strip-shaped thin copper plate 1.
4 and 5 are superposed by heat-resistant adhesive, and a planar heater
Heat insulating films 6 and 7 are adhered to the outer surfaces of 4,5 with the same adhesive.

The copper plate 1 has a thickness of about 0.2 mm and a width of about 10 mm.
It is a strip-shaped plate formed in mm, and the planar heaters 4, 5 are also strip-shaped plates having a thickness of about 0.2 mm and a width of about 4 mm.
Is made to protrude from the end portions of the heat resistant films 6 and 7 by a minute dimension A (= about 0.3 mm) to form the fusing blade 1a. The insulating sheets 2 and 3 have a thickness of about 0.05 mm and a width of about 40 mm, and the insulating films 6 and 7 have a thickness of about 0.25 mm and a width of about 40 mm.
As a whole, the thickness T of this fusing heat edge is about 1.2 to 1.
The thickness is about 5 mm, and since each constituent layer is a thin strip plate having flexibility, it is highly flexible and can be bent in a plane with a small radius of curvature. Then, as shown in FIG. 2, lead wires 8 and 9 for energization are connected to both ends of each of the planar heaters 4 and 5.

On the other hand, FIG. 3 is a cross-sectional view of a main part of a fusing heat edge according to another embodiment. In the above example copper plate 1
The sheet heaters 4 and 5 are superposed on both sides of the sheet with the insulating sheets 2 and 3 interposed therebetween.In this embodiment, the sheet heater 11 is previously covered with an insulating film 12, and the sheet heater 11 is The copper plate 1 is sandwiched and bonded between the heat insulating films 6 and 7 while being bonded to one side with a heat resistant adhesive. In this embodiment, the width of the planar heater 11 is set wider than that in the above-described embodiments in consideration of heat conduction efficiency and bonding strength. Therefore, according to this embodiment, the number of parts is reduced, the structure is simplified, and the structure can be made thinner as a whole, so that further flexibility can be provided.

Next, FIGS. 4 and 5 show a state in which the fusing heat edge (shown in FIGS. 1 and 2) is applied to a packaging sheet covering device (apparatus according to the system shown in FIG. 6). Show. However, FIG. 4 is a cross-sectional view of an essential part of the attachment portion of the heat-dissipating heat edge, and FIG. 5 is a front view of the covering device. The fusing heat edge 20 of this embodiment is attached along the outer peripheral surface of the mold member 21 as an independent strip-shaped component. In addition, as a mounting means, a means is used that fastens each of the heat-resistant films 6 and 7 in the longitudinal direction with screws 23 via strip-shaped stopper plates 22. Since the fusing heat edge 20 has flexibility as described above, it can be attached in close contact with a corner or a curved surface of the mold member 21, and the outer peripheral surface of the mold member 21 is shown in FIG. Since it is formed in a shape corresponding to the cut line 56 in, the fusing blade 1a of the fusing heat edge 20 constitutes the cut line 56 as it is.

The above-mentioned packaging sheet covering device operates as follows. First, as shown in FIG. 6, when the wrapping sheet 54 is pulled down to cover the periphery of the garment 52, the seat 24 moves forward to the back side of the wrapping sheet 54 as shown in FIG.
54 in a state of being pushed slightly forward, in that state, the mold member 21 equipped with the heat edge 20 for fusing and the mold piece 25 for welding move from the surface side of the packaging sheet 54 to the packaging sheet 54 side at the same time, The sheet 54 is pressed toward the seat 24 by the fusing blade 1a and the mold piece 25 for welding.

As a result, the mold piece 25 for welding is wrapped with the packaging sheet 54.
The front and back surfaces are fused and sealed, and at the same time, the fusing blade 1a of the fusing heat edge 20 cuts the packaging sheet 54 along the cut line 56 to efficiently complete the packaging of the garment 52. At that time, the removed portion 57 shown in FIG. 6 is also cut off at the same time, and the standby state for the next packaging process is set.

In the above apparatus, since the copper plate 1 is an extremely thin strip-shaped plate, a sheet-like heater joined through the insulating sheets 2 and 3 (the insulating coating 12 in the fusing heat edge of the embodiment of FIG. 3). Heat is efficiently supplied from 4,5 (11 in the embodiment of FIG. 3), and a heat insulating film is provided on the mold member 21 side and the outer surface side.
Since 6 and 7 are provided, heat dissipation and conduction are suppressed, and since the copper plate 1 itself has an extremely small heat capacity, it can be heated very effectively with a small electric power and its temperature control becomes easy. Furthermore, the copper plate 1 is in a state of being mounted on the tip portions of the two heat insulating films 6 and 7, and when the fusing blade 1a of the copper plate 1 is abutted against the seat 24 side, the heat insulating film is formed.
The elasticity of 6 and 7 exerts an appropriate cushioning function, and it is possible to prevent the fusing blade 1a from deteriorating due to repeated use.

EFFECTS OF THE INVENTION The fusing heat edge of the present invention has the following effects due to the above configuration. (EN) A heat-melting sheet can be stably blown by a free line, and a cutting mechanism most suitable for processing a packaging sheet used when packaging clothes after cleaning is realized. Since the heat capacity of the metal plate that is the heating unit can be reduced,
Efficient heating is possible with a small amount of electric power and the temperature control is easy. Unlike the conventional cutting process with a sharp cutting blade, the cutting edge does not deteriorate, and even if a failure occurs, it can be easily replaced, and the manufacturing and maintenance costs can be significantly reduced. Since it is a simple layered structure, it has the convenience that it can be used by cutting it into one long strip-shaped member and cutting it to a length corresponding to the application site.
