Abstract

PURPOSE:To permit a rapid and accurate attachment of a transfer membrane to a pressure case, by inserting the transfer membrane consisting of an elastic material into an opening defined between a pressure case and a retaining frame, with the transfer membrane in engagement with a hole of the retaining frame and closing the opening of the pressure case airtight with the transfer membrane. CONSTITUTION:An operation plate 2 is moved to a second position B. A fuel tank 6 is securely mounted on a supporting frame 7 and, at the same time, a retaining frame 15 of a transfer membrane is inserted into an opening 13. Next, the operation plate 2 is moved to a first position A and a vacuum case 3 is moved downwardly to enclose a transfer means 8 so as to reduce the inner pressure thereof by operating a suction pump 5. The transfer membrane 11 is then swollen to the side of the fuel tank 6 due to differences in the inner and outer pressures to cause a label L to closely attach to the side wall of the fuel tank 6. The air is thereafter sent pressurized into a pressure case 12 through a flexible pipe 16 and, after the label L is forced against the fuel tank 6 via the transfer membrane 11, external air is introduced into the vacuum case 3 and the pressure case 12, whereby the label L is separated from the transfer membrane 11 and attached to the fuel tank 6.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is suitable for mechanically transferring labels such as trademarks and decorative marks onto curved surfaces such as fuel tanks of motorcycles, reducing manual labor. The present invention relates to a label sticking device, and particularly relates to a device for attaching a label to a thin film made of an elastic material, and applying air pressure to the label so that only the label is attached to the object.

[Conventional technology]

2. Description of the Related Art Conventionally, a technique is known in which a roll-shaped continuous transfer film made of an elastic material with a label is pressed onto the surface of an object having a curved surface using air pressure, and the label is transferred from there to the object. (For example, Japanese Patent Publication No. 41-17335) [Problems to be Solved by the Invention] However, such a transfer device using a continuous transfer film cannot attach a single label to a single-shaped article. However, it is not suitable for high-mix, low-volume production in which labels with different contents, such as the shape of the adhered surface, characters, and drawings, are arbitrarily selected and transferred. That is, in applications that do not use the continuous transfer film, the structure becomes complicated and the apparatus becomes large.

In addition, in order to avoid such problems, when supplying the transfer film one by one and pressurizing one side by supplying pressure, it is not easy to fix the transfer film to the pressure box, resulting in poor work efficiency. If the seal is completely applied, it is not easy to maintain the correct position for attaching the label.

[Means for solving problems]

The present invention solves the above-mentioned problems, and provides a device that quickly and reliably attaches the transfer film to a pressure box and has excellent airtightness in a type of device that supplies transfer films one by one. The purpose of this product is to include a pressure box with an opening facing the object to be adhered to, the inside of which is connected to a pressure source in an intermittent manner, and a small wall on the front side of the pressure box facing the opening of the pressure box. A locking frame having a window hole provided through a gap, and a transfer paper made of a thin film of elastic material having a window hole and a label attached to the window hole are locked at the periphery and inserted into the gap. It is unique in that it is constructed with a removable transfer film holding frame.

[Effect]

If the transfer film made of an elastic material is locked in the window hole of the transfer film holding frame and inserted into the gap formed between the pressure box and the locking frame, the opening will be airtightly closed by the transfer film. When the inside of the pressure box is pressurized, the transfer film bulges outward and is pressed against the object.

〔Example〕

The present invention will be explained below with reference to illustrated embodiments. 1st
The figure is an external view showing the entire device, and a work plate 2 is supported on a bed 1 so as to be movable between a first position A and a second position B. The first position A is a place where a label is pasted on an object, and above it a negative pressure box 3 that moves up and down onto a work plate 2 is provided. The negative pressure box 3 is made into a rectangular shape with an open bottom, and the inside thereof is connected to a suction pump 5 as a negative pressure source via a flexible tube 4. Thus, when the work plate 2 is in the first position, the negative pressure box 3 is placed on its upper surface.
can be lowered to create a negative pressure inside.

Next, to explain the configuration on the work plate 2, as shown in Fig. 2, the fuel tank 6 of the motorcycle, to which the label is attached, is supported at the center in the same attitude as when it is attached to the body frame of the motorcycle. Two pairs of transfer means 8, 8 are provided which are supported by a frame T) and are disposed opposite to each other on both sides with the object to be transferred sandwiched therebetween.

The transfer means 8 is attached to a bracket 9 toward the side of the fuel tank 6.
The structure includes a pressure box 12 whose front side is closed by a transfer film 11 made of a thin elastic film;
It consists of a frame body 14 with a window hole attached to the front face of the opening of the pressure box 12 with a slight gap 13 interposed therebetween. 1
Reference numeral 5 denotes a holding frame that supports the transfer film 11 at its periphery, and its window hole shape is substantially the same as the opening shape of the pressure box 12. That is, like the frame body 14, the holding frame 15 has a frame-shaped rectangular window hole in the center thereof, and the window hole is closed with the transfer film 11. Further, a plurality of holding frames 15 are usually prepared for one pressure box 12.

It goes without saying that the label L to be transferred to the side surface of the fuel tank 6 is attached to the transfer film 11 in advance so that it can be easily peeled off. Further, 16 is a flexible tube that connects the inside of the pressure box 12 to a pressure source (not shown).

Next, the operation of this device will be explained. The work plate 2 is moved to the second position B, which is the attachment/detachment position of the adhered object, the fuel tank 6 is placed and fixed on the support frame T, and at the same time, the transfer film holding frame 15 is inserted into the gap 13.

This state is shown in FIG. That is, the front opening of the pressure box 12 is closed by the transfer film 12.

From this state, the work plate 2 is moved to the first position, the negative pressure box 3 is lowered to cover the transfer means 8, and the suction pump 5 is activated to lower the internal pressure. Due to the pressure difference between the front and back surfaces, the transfer film 11 expands toward the fuel tank 6, and the label L comes into close contact with the side surface of the fuel tank 6, as shown in FIG. Next, pressurized air is supplied from the flexible tube 16 to the pressure box 12, and after strongly pressing the label L against the fuel tank 6 via the transfer film 11, atmospheric air is introduced into the negative pressure box 3 and the pressure box 12. Ba,
As shown in FIG. 6, the label L leaves the transfer film 11 and is attached to the fuel tank 6 side. In this way, the transfer of the label L is completed, and after that, the fuel tank 6 is transferred through the reverse process of
is removed from the holding frame T and the entire work is completed.

〔Effect of the invention〕

As described above, the present invention includes a device for transferring the label L from the transfer film 11 to the object to be adhered 6 using air pressure. The transfer film holding frame with the transfer film 11 attached is inserted between the frame ○ and the transfer film 11 is transferred to the object by the air pressure inside the pressure box 12. It is easy to supply the transfer film 11 and fix it at a working position, and it is possible to perform a complete seal and to accurately affix the label L to a predetermined position on the object.
