The lower pressure member 8 is provided at two positions, a lowered position shown by a solid line in the drawing and a raised position shown by a chain double-dashed line in the figure, so as to be able to move up and down via an elevating mechanism described later.

A large number of pressure resistant hoses 9 extending in the front-rear direction are attached to the lower surface of the upper pressing member 7 in parallel with the left-right direction. Each pressure-resistant hose 9 is sealed at both ends and is filled with air at a predetermined pressure. The pressure resistant hose 9 corresponds to the pressure resistant bag in the present invention.

The lower pressure member 8 is provided with a belt conveyor 10 which intermittently conveys the adhesive plate 6 from the front to the rear (from right to left in FIG. 1A). The belt conveyor 10 is configured with the lower pressure member 8 as a frame, and includes front and rear rollers 12 and a conveyor belt 13 mounted on both rollers.

The specific construction of the pressing apparatus is shown in the front view of FIG. 2, the left side view of FIG. 3 and the plan view of FIG. 2 to 4, the upper pressurizing member 7 is formed by frame-shaped steel material in the form of a grid, and the left and right support legs 14 are formed.
It is supported horizontally by. The support legs 14 are located on both left and right sides of the belt conveyor 10.

As the pressure-resistant hose 9 attached to the lower surface of the upper pressure member 7, an outdoor fire hydrant fire hose is adopted. As shown in FIG. 5, the pressure-resistant hose 9 has a long mounting plate 16 in which stud bolts 15 are planted at predetermined intervals and is inserted into the hose 9.
Further, the stud bolt 15 is inserted into an insertion hole (reference numeral omitted) formed in a continuous manner in the fixed plate 18, and the nut 20 is fastened to the bolt shaft end so as to be attached to the fixed plate 18. The fixing plate 18 is fixed to the lower pressure surface of the upper pressure member 7 by a bolt or the like (not shown). Both ends of the pressure resistant hose 9 are closed by sealing plugs or the like (not shown), and the inside of the hose is filled with air of a predetermined pressure using a known pneumatic circuit. Therefore, the pressure resistant hose 9 when the adhesive plate 6 is pressed is
As shown by the chain double-dashed line in FIG. 5, the cross section is deformed into an oval shape. It is desirable that the pressure-resistant hoses 9 are closely arranged in the left-right direction so as not to come into contact with each other in the left-right direction in consideration of the width of deformation in the left-right direction due to the deformation.

2 to 4, the lower pressurizing member 8 is formed by frame-shaped steel frame material, and a pair of left and right support pieces 22 are projected at the front and rear ends thereof. Support piece 2
A roller shaft 12a of each of the rollers 12 at the front and rear of the belt conveyor 10 is rotatably supported at 2. An endless belt (referred to as a conveyor belt) 13 is wound around both rollers 12 so as to surround the lower pressure member 8, so that the upper linear portion of the conveyor belt 13 is applied to the lower pressure member 10. It faces the pressure surface, ie the upper surface. As shown in FIG. 3, a bracket 23 is attached in a hanging shape to the rear left end of the lower pressure member 8. A drive motor 24 is installed on the bracket 23. The output shaft 24a of the drive motor 24 and the roller shaft 12a of the rear roller 12 are connected to each other through a chain transmission mechanism 25 including a sprocket, and the operation of the drive motor 24 causes the conveyor belt 13 to rotate counterclockwise in FIG. Rotate in the direction.

2 and 3, the interlocking arm 2 is attached to the bearing member 26 fixed to the upper surface of the upper pressure member 7.
The lower end side crankshaft 28 of 7 is rotatably supported. The interlocking arms 27 form a pair of left and right and are arranged in three pairs in the front-rear direction. The eccentric shafts 29 on the left and right of the crank shaft 28 of each interlocking arm 27 are rotatably connected to the upper ends of a pair of left and right suspension members 30 that are substantially U-shaped. The lower pressure member 8 is coupled to the lower end of each suspension member 30 with a bolt or the like.

The tip of each interlocking arm 27 is rotatably connected to the left and right frame members of the interlocking frame 32 framed in a rectangular frame shape via pins 33. Further, the front frame of the interlocking frame 32 and the pillar 35 standing upright at the center of the upper pressure member 7.
As shown in FIG. 4, both ends of the hydraulic lifting cylinder 36 are rotatably connected to the upper end of the pin via pins 37 and 38. Therefore, the extension / contraction motion of the lifting cylinder 36 causes the interlocking frame 32 to move to two positions, the retracted position shown by the solid line in FIG. 3 and the front position shown by the chain double-dashed line in FIG. All the interlocking arms 27 rotate in synchronism with the rotation of the crankshaft 2.
All of the suspension members 30 move up and down in synchronization with each other via 8, and the lower pressure member 8 moves up and down in a horizontal state.

Next, the operation of the pressing device will be described. Before the operation, the lifting cylinder 36 is shortened as shown in FIGS.
Is in the lowered position. In this state, the adhesive plate 6 is placed on the conveyor belt 13 of the belt conveyor 10 at the front of the device.

Drive motor 24
Stop the operation of.

Then, the lifting cylinder 36 is extended and
When the interlocking frame 32 is moved to the front position shown by the chain double-dashed line in FIG. 3, the lower pressure member 8 is raised together with the belt conveyor 10 via the elevating mechanism mainly including the interlocking arm 27,
As a result, the adhesive plate 6 rises together with the upper linear portion of the conveyor belt 13, and the adhesive plate 6 is pressed by the pressing members 7 and 8.

At the time of this pressurization, the pressure resistant hose 9 of the upper pressurizing member 7 is deformed according to the shape of the surface to be pressed of the adhesive plate 6,
The surface to be pressed is pressed by the fluid pressure of the pressure resistant hose 9. Therefore, when the laminated plate 1 as shown in FIG. 12 is pressed, even if the upper surface (pressurized surface) is a stepped surface, the pressure resistant hose 9 is deformed according to the stepped shape, The gypsum board 3 can be pressed without deforming the flange 2a of the base material 2. Therefore, the adhesive plate 6 can be pressed with a uniform pressure over the entire surface regardless of the stepped shape of the surface to be pressed, which is suitable for pressing the stepped adhesive plate 6 such as the laminated plate 1. Further, if the size and shape of the adhesive plate 6 are within the range where the pressure-resistant hose 9 faces, it is not necessary to replace the pressure member, so that the adhesive plate 6 having a deformed shape can be used. It is also possible to control the pressure applied to the adhesive plate 6 by adjusting the pressure with which the pressure-resistant hose 9 is filled. Further, since a fire hose for outdoor fire hydrant is adopted as the pressure resistant hose 9, it is possible to form a pressure resistant bag with a commercially available product, which is advantageous for cost reduction.

After the pressurization, when the lifting cylinder 36 is shortened to move the interlocking frame 32 to the rear position shown by the solid line in FIG. 3, the lower arm is driven by the interlocking arm 27. The pressure member 8 is lowered together with the belt conveyor 10, whereby the adhesive plate 6 is also lowered. Then, by driving the drive motor 24 and rotating the conveyor belt 13, the adhesive plate 6 is carried out to the rear of the apparatus. As described above, according to the pressing apparatus of the present embodiment, the adhesive plate 6 can be intermittently conveyed by the belt conveyor 10 and subjected to the batch pressure treatment.

The belt conveyor 10 in the first embodiment
It is also possible to eliminate the above function and make the upper surface of the lower pressure member 8 directly face the pressure resistant hose 9 of the upper pressure member 7. In this case, the adhesive plate 6 is attached to the upper surface of the lower pressure member 8.
Can also be placed manually or through a charging device and subjected to pressure treatment as described above. After the pressure is applied, the adhesive plate 6 may be taken out from the pressure member 8 manually or by a charging device. Further, in the case of the first embodiment, it may be considered that the lower pressure member 8 is fixed so as not to move up and down, and the upper pressure member 7 is movable up and down with respect to the pressure member 8. The pressure-resistant hose 9 may be replaced with a pressure-resistant bag such as a mat-shaped bag or a ball-shaped bag, and may be attached so as to cover almost the entire pressure surface of the pressure member.
