る。The continuous vacuum forming described above is performed, for example, as shown in FIG. That is, the sheet 1 is placed near both edges of the sheet 1a pulled out from the raw roll sheet 1 made of thermoplastic resin.
The DC turbo motor 2 is arranged along both sides of the longitudinal edge of a.
A chino 3 is provided which is driven by. This ceno 3 has needles (not shown) attached at predetermined intervals. Both ends of the sheet 1a are pierced by this needle, and the sheet 1a is conveyed.

When the C turbo motor is stopped and the heating machine 4 is brought into contact with the stopped sheet 1a from above and below, and the thermoplastic resin is amorphous, the thermoplastic resin is heated at a temperature slightly higher than the softening temperature, and when the thermoplastic resin is amorphous. In this case, the sheet la is heated to a temperature slightly higher than the melting temperature, and the sheet la is softened or melted (hereinafter referred to as "softening").

して成形する。Next, the heating machine 4 is separated and the sheet 1a is moved. When the softened part reaches the position of the molding machine 5, the sheet 1a is stopped again, brought into contact with the upper mold 6, and heated by a vacuum pump (not shown). A valve (not shown) between the vacuum tank 7 and the vacuum tank 7 is opened, and the material is sucked into the upper mold 6 and molded.

These molded products are cooled and solidified while in contact with the mold 6. While this heated and softened portion is being molded and cooled, the subsequent sheet la is heated by the heating machine 4.

る。In addition, in the pressure forming, as shown in FIG. 6, the sheet 1a pulled out from the raw roll sheet 1 is conveyed by a chino 3, guided onto a heating machine 11 having a built-in heater 11b in the lower part of the iron plate 11a, and then The container 13 in which pressurized air is stored is softened by contact with
The valve (not shown) is opened to eject water from the heater 11 side, and the softened sheet is pressed into the cavity and molded.

った。In addition, recently, we have been printing on raw roll sheets in advance,
It is now possible to obtain molded products with printing in place.

刷が施された成形品がつくられる。When printing on the raw roll sheet 1, a color mark is simultaneously printed on the edge of the sheet 1a, and a phototube is installed near the mold of the molding machine to detect the color mark. At the time of detection, the sheet la is printed at a predetermined position with respect to the mold, and conveyance of the sheet is stopped and molding is performed to produce a molded product with the print at the predetermined position. It will be done.

形には、連続圧空成形法が用いられている。In this case, in continuous pressure forming, the sea hla is conveyed onto a heating machine 11, heated and softened by an iron plate 11a, and held down by an air pressure mold 12 that moves up and down and is provided opposite to the iron plate 11a. Molding is performed. Therefore, in order to maintain the correct position of the printing on the sheet 1a relative to the mold 12, a continuous pressure forming method is used to form the printed sheet.
ところで、深絞りの場合には、真空成形法が望ましい。 By the way, in the case of deep drawing, a vacuum forming method is preferable.

成形は行われていない。However, in the continuous vacuum forming method, since the heating machine 4 and the forming machine 5 are arranged in parallel with an interval, the heated and softened sheet 1a tends to sag and is transferred to the forming machine 5. Even if the position of the color mark is detected correctly, the printing of the sheet 1a with respect to the upper mold 6 may be misaligned, and a molded product with printing at the correct position cannot be obtained. Therefore, continuous vacuum forming using printed raw roll sheets has not been performed.

刷２２を施す時に、同時に印刷される。The reference numeral 21 in the figure is a printed raw roll sheet. As shown in FIG. 3, printing 22... is regularly applied to this raw roll sheet 21, and the printing 22 is heated by upper and lower heating machines 23, 24, and is heated by a forming machine 25. One block 28 is formed by one printing molded by the mold 26 and the plug 27 . These blocks 28 are arranged in the length direction of the sheet 21 at the same intervals as the intervals between the upper and lower heating machines 23 and 24 and the molding machine 25. Furthermore, each block 28
. . , a color mark 29 is provided at a predetermined 7th edge position. These color marks 29 are printed simultaneously when printing 22 is applied.

正確に位置するようになっている。The upper and lower heaters 23, 24, mold 26, and plug 27 are each provided with a cylinder 30 that moves them up and down. Furthermore, on the raw roll sheet 21 side of the upper and lower heating machines 23 and 24 and on the sheet drawer side of the molding machine 25, photocells 31 and 32 for detecting the color mark 29 are installed.
are arranged so that when the phototube 31 or 32 detects the color mark 29, the block 28 is accurately positioned between the upper and lower heaters 23, 24 and between the mold 26 and the plug 27. It has become.

２１ａを挾持し、加熱部３５で軟化させる。In order to continuously vacuum form a molded product with printing applied to a predetermined position using the above device, the sheet 21a is pulled out from the printed original roll sheet 21, and the chino 3 is driven by the DC servo motor 2. Then, the /-tooth 21a is run. At this time, since there is no printing on the front part of the sheet 21a when the sheet 21a starts running, the position is detected by the phototube 31, and the position is detected between the upper and lower heating machines 23, 24, and the upper and lower parts are stopped. The sheet 21a is held between the heaters 23 and 24 and softened by the heating section 35.

ンク７と連通され、真空成形が行なわれる。Since the heating part of this heating machine is surrounded by the water cooling part 34 of the heating machine, the softening of the sheet 21a is limited to the part heated by the heating part 35, and the other parts are kept at a low temperature and do not sag. It will not be stretched or stretched. Then,
The upper and lower heating machines 23 and 24 are separated and run. In this case, the phototube 31 is switched to 32, the color mark 29 is detected, and the running of the /-t 21a is stopped. At this time, the softened resin 28 is precisely positioned between the mold 26 and the plug, and at the same time as the mold 26 descends, it is communicated with the vacuum tank 7 and vacuum forming is performed.
また必要に応じてプラグ２７が上昇し、真空成形された

ロックは上下の加熱機によって所定部分が軟化される。Further, the plug 27 may be raised as necessary to make the wall thickness of the vacuum-formed product uniform. During this time, predetermined portions of the succeeding blocks are softened by the upper and lower heating machines.

が、ずれたりすることがない。In this way, since the heated part is surrounded by the water-cooled part, the parts other than the softened parts are kept at a low temperature, and the sheet 21a sags, causing the softened parts to move to the mold. The printing on the molded product will not be misaligned.

In addition, although the water-cooled part is used as a base pattern, if the water-cooled part is provided on both edges of the heating part as shown in Fig. 4, the sheet edges will not be heated, so printing on the molded product will not be possible. The position of is held almost constant.

絞りのものが成形可能となる。Table 1 [Effects of the Invention] As explained above, in the continuous vacuum forming method of the present invention, the vicinity of both edges of the sheet being run is not softened at all, so the sheet can be formed without sagging or stretching. The molded product runs in the correct position and is heat-softened or vacuum-formed to efficiently produce a molded product with printing applied to the specified position.Moreover, it is possible to efficiently obtain a molded product with a uniform wall thickness and deep drawing, which cannot be obtained with pressure-forming. Things can be molded.
