Cylinder rods 78a and 78b of a and 72b are respectively extended upward, and flanges 79a and 79b are respectively fixed on the way.

A plate body 80 is bridged between the ends of the cylinder rods 78a and 78b, and a stud 86 is engaged with the plate body 80 which is threadedly engaged with a plate body 84 bridged between the guide rods 82a and 82b. The guide rods 82a, 82b extend upward from the base 70, as can be seen from the figure. stud 86
is rotatable by a handle 92 which rotates via a bushing 90 fixed to a plate 87 bridged over the tips of the guide rods 82a, 82b. In addition, the cylinder rod 78
flanges 79a, 79 disposed at the tips of a, 78b;
Coil springs 94a, 9 between b and the plate body 80
4b, the cylinder rods 78a and 78b are always connected.
This coil spring 94 provides an elastic force that presses the
a, 94b. conduit 60
Pressure fluid, such as pressure oil, passes through a passage (not shown) drilled in the base 70 to the cylinders 72a, ? 2b, respectively.

FIG. 5 shows a longitudinal sectional view of the cylinders 72a and 72b. Since the cylinder 72b has substantially the same structure as the cylinder 72a, only the 7-ring 72a will be described.

First, one end of the cylinder body 100 is closed by a sealing member 102, and the other end is fitted with a fitting member 104, 106 similarly to the cylinder 30, and the other end of the cylinder body 100 is closed. The fitting member 106 and the sealing member 108
This cylinder body 100 is sealed by brazing.

Sealing member 102 defines a tapered opening 110, while sealing member 108, mating member 106.10
Cylinder rod through the hole communicating with 4? 3a faces the inside of the cylinder body 100, the cylinder rod 7
A disk 112 constituting a piston is fixed to the tip of 8a.

The pasting device according to this embodiment is basically constructed as described above, and its operation and effects will be explained next.

By rotating the handle 92, the stud 86 rotates, and the plate body 80, which descends thereby, resists the elastic force of the coil springs 94a, 94b and moves toward the cylinder rod 78.
Lower a and 78b. As a result, the cylinder 72a,
? Pressure fluid, such as pressure oil, sealed in advance in 2b is led out to the pipe line 60 side through the hole 110 and reaches the cylinder 30. That is, the rotational action of the handle 92 is uniformly applied to the cylinder rods 78a, 78 of the cylinders 72a, 72b.
8b and then drive the cylinder 30.30. That is, the pressure oil introduced from the hole 40 presses one surface of the disk 46, and this disk 46 resists the elastic force of the coil spring 48 and displaces the cylinder rod 44 in the direction of the arrow in FIG. let As a result, the bracket 56 is displaced, and the roller 58 is displaced in position relative to the core material 4, changing the pressing force. That is, it is possible to displace the rollers 58, which are engaged with the plurality of secondary cylinders 30, by a desired distance in accordance with the rotation of the handle 92. In other words, it is possible to drive a plurality of cylinders 30 at once under the operation of the handle 92 and adjust the position of the roller 58 fixed to the tip thereof.

The core material 4 is fed under the rotational action of the feed roller 6 to the roller 58 whose position has been adjusted in this way, and the thin plate A
is attached to the core material 4.

Next, when trying to attach the thin plate A to a different core material 4,
In the secondary cylinder 30, its roller 58 must be displaced. At this time, when the handle 92 is rotated in the opposite direction, the plate 80 is displaced upward, and the cylinder rods 78a and 78b are similarly elevated. by this,
Since the discs 112 of the cylinders 72a and 72b rise, the pressure oil easily flows in from the secondary cylinder 30 via the conduit 60. Therefore, in the secondary cylinder 30, the disk 46 is upwardly displaced by the elastic force of the coil spring 48, and the pressure oil flows through the hole 40 to the primary cylinders 72a, 7.
It is fed to the 2b side. Therefore, as a result, the position of the roller 58 is set according to the shape of the next core material 4.

In the embodiment described above, the two cylinders 72 on the primary side
a, 72b are respectively connected to the two cylinders 30, 30 on the secondary side via the conduit 60, and the two cylinders 72a, ? 2b is equally displaced under the displacement action of the plate body 80, and the secondary cylinders 30 and 30 are equally displaced by pressure oil of the same pressure derived from the cylinders 72a and 72b. However, as shown in FIG. 6, for example, if the primary cylinder 200 is made to have an extremely large diameter,
2 into the manifold 204, and
Three pipe lines 206a to 206 on the outlet side of 04
The same effect can be obtained by connecting the secondary cylinder 30 to each of the conduits 206a to 206C.

In this case, the number of primary cylinders 200 can be reduced, and the number of piping between the primary cylinders 200 and the manifold 204 can also be reduced.

FIG. 7 shows another embodiment of the present invention.

In this embodiment, instead of the configuration in which the support arm 8 is curved as described above, a rod 300 is provided upright on the base 2, and a bracket 302 is fixed to the tip of this rod 300. A rod 304 further extends from the bracket 302, and a separate bracket 306 is fixed to the tip of the opening/door 304. And this bracket 30
A hole 310 is formed in the bracket 308 which holds the secondary cylinder 30 in a vertical state by the G and also holds the cylinder body 32 of the cylinder 30, and a guide member 312 is inserted into the hole 310. Further, the tip of the guide member 312 is engaged with a bracket 314, and the pressure roller 2 is fixed to the tip of the cylinder rod 44 extending from the cylinder 30 by the bracket 314.
It holds 0.

With the above configuration, the position of the bracket 302 with respect to the rod 300 is basically adjusted, and fine position adjustment is performed by the pressing roller 20 under the biasing action of the secondary cylinder 30.
This can be solved by displacing the tip of the

According to this embodiment, as described above, it is possible to adjust the positions of a plurality of pressing rollers 20 for pasting thin plates at once with an extremely simple configuration.

Therefore, the configuration is simplified and the position adjustment of the plurality of pressing rollers 20 can be performed extremely quickly and accurately.

[Effects of the Invention As described above, according to the present invention, with a simplified configuration,
For example, it is possible to adjust the pressing force with which the thin plate is pressed against the core material. Therefore, especially in devices where the number of pressure rollers increases, the position of the pressure rollers can be adjusted all at once, the work efficiency required for position adjustment is promoted, and the operation is extremely simple. Effects can be obtained.
