Brackets 21 are attached near the four corners that do not hinder the loading and unloading of the brackets, and a gate-shaped restrictor 22 is bridged between these adjacent brackets 21 and one end of the bracket 21 is attached to the bracket 21. The other end is set as a free end, and the free end of the restrictor 22 is locked to the bracket 21 when the press is opened, and the left and right spaces of the heating plate 9 and the movable plate 10 are evenly held.

6 to 7 show another embodiment of the above-mentioned restricting tool 22. In the one shown in FIG. 6, a pin 23 is planted in a hot plate 9 and a hot plate is provided between the pins 23. 9 is a ring 24 that allows the maximum opening, and in FIG. 7, brackets 25 attached to the hot plate 9 are perforated, and a round bar 26 is inserted into this perforated portion. One end of the heating plate 9 is fixed and the other end of the lock nut 27 is slidable so that the maximum opening of the heating plate 9 is restricted.

Next, a pair of notched grooves 28 are formed at an arbitrary interval in the lower part of the heating plate 9, and below the notched grooves 28, a plurality of plate members 13 for carrying in, supporting, and carrying out the plate member 13 to be processed are provided. A conveyor 30 made up of rolls is attached to a machine frame 30 on the lower cross beam 2.
Place it in between.

Further, by interposing in the pair of notch grooves 28,
A pair of push-up members 31, which correspond to the lengths of all the hot plates 9 when the press is opened, can be screwed, rack-and-pinion-moved, or as shown in the drawing so that the push-up members 31 can be retracted from the transfer surface of the transfer conveyor 29. It gives rise and fall by fluid movement. Specifically, the push-up fluid cylinder 3 is attached to the support frame 32 that is laid horizontally between the lower horizontal beams 2.
3 is fixed in the opposite direction, and a guide rod 36 for supporting the push-up body 31 is connected to both ends of a connecting beam 35 suspended from the tip of the piston rod 34, and the guide rod 36 is also supported. It is inserted through a guide ring 37 on the frame 32 to regulate its balanced lifting.

As shown in the drawing, a fluid cylinder 38 is attached to the lower end of the connecting beam 35, and its piston rod 3 is attached.
In some cases, due to the expansion and contraction of 9, the push-up body 31 is fitted into the push-up body 31 with a space therebetween, and the operating piece 40 having a thickness substantially equal to the space between the heat plates 9 is rotated around the push-up body 31 as a fulcrum.

Next, the operation will be described. First, when the fluid cylinder 11 is operated to reduce the ram 12, the movable platen 1
0, while the hot plates 9 of each stage are suspended from the upper cross beam 1 by the moving member 8, one side is kept parallel by the engaging movement of the ruler 6 and the engaging portion 7, Move to the center right. During this movement, from the hot plate 9 located at the left end, the free ends of the restrictors 22 contact the brackets 21 of the adjacent hot plates 9 at the four corners of the hot plate 9, and the maximum opening thereof is sequentially restricted, whereby each step is closed. The horizontal spacing of the heating plate 9 is evenly maintained, and the press is opened.

Next, the plate members 13 to be processed are carried in all at once from the loader located on the carry-in side into the space between the heating plates 9 of the respective stages in which the heating medium has been supplied and maintained at the required temperature. The plate 13 to be processed, which is carried in, has its lower end supported by the drive of the transport conveyor 29, is transported to the central position in the front-rear direction of the hot plates 9 of each stage, and is stopped at that position.

At this time, if the piston rod 34 is contracted by the operation of the push-up fluid cylinder 33 and the connecting beam 35 is pulled up, the push-up body 31 that has been depressed below the transfer surface of the transfer conveyor 29 becomes a guide rod 36. The lower end of the plate 13 to be processed which is projected through the sliding of the guide ring 37 and is supported in parallel on the transport conveyor 29 is lifted to intervene between the pair of notched grooves 28 of the hot plate 9. (See Figure 9)

Therefore, the plate body 13 to be processed reaches the hot plate 9 even in the vertical direction, and in this state, the fluid cylinder 1
When the ram 12 is extended by the operation of No. 1, the moving members 8 on both sides of the upper part move along the rails 5, so that the movable platen 10 causes the hot plate 9 of each stage in which the plate member 13 to be processed is inserted.
Are sequentially pressed to the left, and the press is closed.

After the press is closed, each plate 13 to be processed is heated and pressed by the heating action of the hot plate 9 and the pressurizing action of the fluid cylinder 11. Since it is suspended, the pressure applied to the plate body 13 to be processed becomes uniform at each stage.

After the heating and pressurization is completed, the fluid cylinder 11 is operated again to reduce the ram 12 so that the press is opened, and the lifting fluid cylinder 33 is operated.
By immersing the push-up body 31 into the surface of the transfer conveyor 29, the plate 13 to be processed is transferred onto the transfer conveyor 29 to be carried out to the unloader. When the adhesive, the wood resin, etc., which have been adhered, leaks and adheres to the surface of the hot plate 9 and the plate body 13 to be processed comes into close contact with the surface of the hot plate 9, the fluid cylinder 38 is activated as shown in FIG. Then, if the operating piece 40 set to have substantially the same thickness as the space between the hot plates 9 is rotated about the push-up body 31 as a fulcrum, the operating piece 40 lifts the plate body 13 to be processed within the space between the hot plates 9. It draws a circular locus to easily release the close contact.

When the dimensions of the plate 13 to be processed are different while the work is being continued, for example, from the one shown in the left half of FIG.
When the dimension becomes small as shown in the right half, the stepping screw 16 is screwed to lower the sliding plate 15 along the sliding guide 14, and the fluid cylinder 11 is reduced in size. The position of the processed plate 13 is changed so that it is located in the vertical direction. At this time, the ram 12 is also synchronized with the lowering of the fluid cylinder 11, and the sliding plate 15 is lowered along the sliding guide 17 to change its position.

Bending and peeling can be prevented.

Furthermore, the fluid cylinder and the ram are
If it is possible to move up and down integrally along the sliding guides attached to the frame and movable plate, the height of the fluid cylinder and ram can be adjusted according to the dimensions of the plate to be processed carried in between the hot plates. It is possible to expect an even adhesion effect by adjusting and applying heat and pressure so that the pressure point is always the center position in the vertical direction.
In one horizontal multi-stage press, it is possible to heat and pressurize a plurality of types of plate bodies having different dimensions.
