Teflon covers 15 and 25 are adhered to the surfaces of the spring leaf members 14 and 24, respectively, so that the tape does not directly contact the spring leaf members 14 and 24 when the tape is welded.

Heating surfaces 113 and 213 and spring plate member 1
The seating surfaces 18, 28 between the screwing positions 4 and 24 include:
Flange members 13 and 23 are attached. This collar member 13,

Therefore, the main body member 10,
When the tool 20 is placed on the worktable, the curved portions of the flange members 13 and 23 and the base ends of the main body members 10 and 20 contact the worktable, and the main body members 10 and 20 do not directly contact the worktable. It has become.

On the outer peripheral surfaces of the main body members 10 and 20, the flange member 1 is slightly shifted from the heat generating surfaces 113 and 213 toward the base end side.
A plurality of heat radiation holes 12,
22 is formed to prevent heat from the heat generating portions 11 and 21 from being transmitted to the base end side.

A pilot lamp 34, which is lit when the power of the power supply unit 30 is turned on, is provided on the base end side of the main body members 10, 20.
Is provided.

The power supply unit 30 can be used by inserting a plug 304 into an outlet and turning on a switch 310 provided on the front panel, and by making the output voltage variable with a dip switch 303, the heat generating members 112 and 212 can be used.
The exothermic temperature can be adjusted. The heating temperature adjusted at that time is digitally displayed on the display 302.

When the tapes 51 and 52 are welded in the tape welding apparatus 1 having the above structure, the spring plates 14 and 2 are used.
4, the tapes 51 and 52 are overlapped and interposed, and the main body members 10 and 20 are closed. When the body members 10 and 20 are closed,
Since the spring plate members 14 and 24 are pressed against the heat generating surfaces 113 and 213, the protrusions 114 and 214 are
24 slightly protrude from the window holes 144, 244. Then, the tapes 51,
52 are heated and pressed to be welded to each other.

The tapes 51 and 52 are irona tapes made of, for example, a heat-resistant fiber material, and the melting temperature differs depending on the material in the range of about 200 ° C. to 350 ° C. Adjust the temperature at which the material melts before use.

As described above, in this embodiment, the tapes 51 and 52 are connected by welding, so that the tapes 51 and 52 can be firmly connected so as not to be easily cut. .

Since the welding is performed via the spring plate members 14 and 24, the tapes 51 and 52 are attached to the heating surface 11
3, 213 without touching directly, and the spring plate member 14,
Normally, the temperature is not so high because it is separated from the heat generating surfaces 113 and 213 at normal times, and even if the tapes 51 and 52 before welding touch the spring plate members 14 and 24, they rapidly melt. And therefore the tapes 51, 52
Of the heating surface 11
3, 213 can also be prevented from becoming dirty. The temperature of the spring plate members 14 and 24 becomes high at the time of welding, but it is also instantaneous only at the time of welding.
It does not become dirty with melting waste.

In addition, the heating pressure welding during welding is
Since the heat is generated at 214, the heat of the heat generating surfaces 113 and 213 is concentrated on the protrusions 114 and 214, and the pressing force is also concentrated on the protrusions 114 and 214. Therefore, welding can be performed more effectively in a short time. Can be.

Since the distal ends of the spring plate members 14, 24 are bent along the distal end shapes of the main body members 14, 24, the tapes 51, 52 can be smoothly guided to a predetermined welding position when setting. , Making welding work easier.

The springs 3 are attached to the main body members 10 and 20.
Since the body 3 and the stopper 32 are provided, the main body members 10 and 20 are normally opened at an appropriate opening degree and need only be slightly pressed at the time of welding, so that usability can be improved.

The main body members 10 and 20 have flange members 13 and
With the provision of 23, even if the main body members 10, 20 are placed on the worktable, the worktable comes into contact with the flange members 13, 23, and it is possible to prevent the worktable from being scorched by heat. . In addition, since the user does not grasp the front end side having a higher heat than the flange members 13 and 23, it is possible to prevent inadvertent burns.

Further, since the heat radiating holes 12 and 22 are formed in the vicinity of the flange members 13 and 23, the flange members 13 and 23 are formed.
Therefore, the temperature on the base end side is lowered to a temperature at which the hand can be sufficiently grasped by hand, and the welding operation can be performed with confidence.

Since the Teflon covers 15 and 25 are adhered to the spring plate members 14 and 24, the temperature of the spring plate members 14 and 24 becomes high and the tape 5 becomes high for continuous welding work.
Even if 1,52 melting scum comes to adhere,
It can be easily removed from the Teflon covers 15, 25. Therefore, the spring plate members 14 and 24 can be reliably prevented from being contaminated in any use state.

[0032]

Since the present invention has the above-described configuration,
The following effects can be obtained. According to the first aspect of the present invention, since the connection of the tape is performed by welding, the tape can be firmly connected so that the tape is not easily cut.

Since the welding is performed via the spring plate member, the tape does not directly touch the heating surface, and the spring plate member is normally separated from the heating surface so that the temperature is not so large. It is not raised, and even if the tape before welding touches the spring plate member, it does not melt rapidly, so it is easy to handle such as tape setting, and the heating surface can be stained with melting scum. Can be prevented. The spring plate member becomes hot at the time of welding, but it is also instantaneous only at the time of welding, so that the spring plate member does not become dirty with melted scum.

According to the second aspect of the present invention, since the heating and pressing during welding is performed by the projection, the heat of the heat generating surface is concentrated on the projection and the pressing force is also concentrated on the projection. The welding can be performed more effectively in a short time.
