In FIG. 3, a movable base 4a of the pressing body 4 is shown.
Stopper cylinder 1 attached to bolt 19
Numeral 8 denotes a piston rod 18a which is inscribed in an alignment hole 26 formed in the movable base 4a and interferes with a through hole 27 formed in the cushioning member 4c and a through hole 28 formed in the pressing surface member 4b. Penetrated with a play fit so as not to. The stopper 17 has a through hole 30 having substantially the same diameter as the bolt 29 at the center of a rod formed of a soft synthetic resin having such a hardness as not to damage the game board 1b of the article 1 to be pressed. The bolt 29 is inserted into the through hole 30 and fastened to the screw hole 31 formed at the center of the lower end surface of the piston rod 18a, so that the bolt 29 is attached to the piston rod 18a. The bolt 29 is a screw called a set screw, has a tool hole (not shown) at its head, fits a tool (not shown) such as a hexagon wrench into the tool hole, and fastens with the tool.

The pressurizing surface member 4b has a through hole 33 formed in the peripheral portion thereof.
The bolt 13 is loosely inserted into the through hole 34 formed in the flange 4d of the movable base 4a, and the nut 14 is fastened to the bolt 13 protruding upward from the flange 4d, so that the movable base 4a is elastically shaped like a flat plate. It is mounted so that it can be deformed.

Although not shown in FIG.
a guide rails for guiding the object to be pressurized 1 in the conveying direction X on both sides of the upper conveying section 2c in the conveying direction X so as to prevent interference with the pressing body 4 It is arranged at a height of less than 1 thickness. Reference numeral 23 in FIG. 1 denotes a bolt in which the pressure cylinder 6 is attached to the upper beam 5.

According to this embodiment, as shown in FIG. 1, the pressing body 4 is stopped at the retreat position, and the game board 1b is carried above the receiver 3 by the carrying operation of the carrying band 2a. The stopper 17 at the lower limit position, and at the same time, the transport operation of the transport band 2a is stopped. Then, the stopper 17 ascends, stops at the ascending limit position, and sinks toward the movable base 4a. Next, the pressurizing body 4 is lowered, and the pressurized object 1 having the cell sheet 1a mounted on the game board 1b with an adhesive interposed therebetween is sandwiched between the receiver 3 and a normal temperature. Pressurization is performed for a certain time.

In this pressurizing process, the pressurizing surface member 4b, which is curved so as to swell in advance, is elastically deformed so as to gradually contact from the center to the peripheral side of the article 1 to be pressurized. Thus, a uniform pressing force can be applied to the entire area of the article 1 to be pressurized.

In addition, since the movable base 4a is swingably connected to the pressing cylinder 6, the pressing surface member 4b, which is elastically deformed, is not subjected to a force in an unreasonable direction, and the pressing surface member 4b is pressed against the pressing target member 1. Along its surface, it can be gradually elastically deformed from its center to its periphery.

Further, when the pressing surface member 4b is elastically deformed,
When the cushioning member 4c interposed between the pressing surface member 4b and the movable base 4a contracts, the pressing surface member 4b elastically deforms following the surface of the article 1 to be pressurized. Even if the surface of the target product 1 is wavy as compared with the mirror surface, the pressing surface member 4b uniformly presses the surface of the cell sheet 1a while moving from the center to the peripheral edge side.
The entire surface of “a” is anchor-bonded to the game substrate 1b with an adhesive, so that the inconvenience of partial peeling of the cell sheet 1a can be eliminated.

After the pressurization for a certain period of time, the pressurizing surface member 4b
Rises and stops at the evacuation position. In this case stopper 1
7 retreats above the lower surface of the pressurizing surface member 4b when stopped at the above-mentioned ascending limit position, and retreats from the transport path of the game board 1b. Therefore, when the transporting band 2a restarts the transporting operation, the pressurized product 1 after the pressure coupling is carried out from the receiver 3 to the next process and a new pressurized product 1 is obtained.
Is carried to the position of the receiver 3, and one cycle of a pressurizing operation at normal temperature called a cold press is completed.

In the process of raising the pressing surface member 4b, the cushioning member 4c is restored, and the pressing surface member 4b is restored to a curved shape, so that the article 1 to be pressed can be prevented from being carried.

Further, since the buffer member 4c is connected to the lower surface of the movable base 4a, the buffer member 4c can be stably installed.

In this embodiment, the pressing surface member 4b is shown curved in the transport direction X.
May be curved in a direction orthogonal to the transport direction X, and the bolts and nuts 13 and 14 may be positioned outside the pressurized object 1 on both left and right sides in the transport direction X.

FIG. 4 shows a second embodiment, in which a pressing member 4 is integrally attached to a lower surface of a movable base 4a. The pressurizing surface member 4d is made of an elastically deformable material such as rubber or synthetic resin, and is formed in a hollow shape like a balloon, and its lower surface is curved so as to bulge downward in advance into a hemisphere. A pressurized fluid such as an electric air compressor having a through hole 4g formed on the pressure lower surface 4e and having a peripheral wall communicating with the hollow interior 4f, and a regulator 40 with a relief valve interposed in the through hole 4g. Piping the supply source 41,
Pressurized air as a pressurized fluid is supplied from the pressurized fluid supply source 41 to the hollow interior 4f via the regulator 40. The pressurizing body 4 descends toward the pressurized article 1 conveyed and stopped on the conveying line 2 directly below the pressurized body 4, and the pressurizing surface member 4 d moves the pressurized article 1 with the receiver 3 via the conveying band 2 c. As if pressurized to a sandwich, the regulator 40
When the internal pressure from the hollow interior 4f to the regulator 40 becomes higher than the set pressure set for the relief valve of the regulator 40, the relief valve of the regulator 40 automatically releases the internal pressurized air to the outside (relief). )

According to this embodiment, the pressurizing surface member 4d of the pressurizing member 4 moves the article 1 to be pressurized to the receiving member 3 via the transport band 2c.
When the pressing body 4 is pressed, the lowermost center portion of the pressing lower surface 4e first comes into contact with the center portion of the article to be pressed 1 with the lowering of the pressing body 4, and then the pressing is continued. The pressing lower surface 4e is elastically deformed so that the peripheral portion of the central portion of the lower surface 4e gradually comes into contact with the peripheral portion of the central portion of the object 1 to be pressed. Is pressed evenly as if by hand, so that the inconvenience of partial peeling of the cell sheet 1a from the game substrate 1b in the article 1 to be pressed can be eliminated.

This embodiment shows a structure characterized in that the pressing surface member 4d is formed in a fluid bag which can be elastically deformed. Therefore, to simplify the drawing, FIG. The peripheral mechanisms such as the ring 12, the guide mechanism 20, the stopper 17, the stopper cylinder 18, and the like are not shown.
