Description

Detailed Description of the Invention "Industrial Application Field" The present invention is a method for moving a board to be treated, such as plywood, decorative board, or veneer veneer, in the left-right direction while being supported on both upper and lower sides or on both upper and lower sides. The present invention relates to a horizontal multistage press that heats and presses between multiple hot plates, which are freely adjustable and are arranged side by side at equal intervals when the press is opened.

``Prior art'' The multi-stage press, which is usually used mainly in the plywood manufacturing process, has a movable platen that can be raised and lowered by a ram cylinder installed in the lower frame, and is equipped with multiple stages of hot plates between the upper and lower frames. After the plate to be processed is inserted and placed between these hot plates, the movable platen is raised, and the hot plate located above is successively pushed up, starting from the lowest hot plate, and the press is closed, heating for the required time. 0 ``Problem to be solved by the invention'' However, in this type of multi-stage press having multiple upper and lower heating plates, it is difficult to support each heating plate at each stage. On this occasion,
A system is adopted in which support claws are attached to the four corners, and these support claws are sequentially placed on ladder-like supports that are attached to pillars.

Therefore, when determining the thickness of the hot plate at each stage, in addition to the strength required for heating and pressing the plate to be processed, which is the main purpose,
In order to provide rigidity, taking into consideration the strength corresponding to the deflection and bending caused by the distance between the fulcrums, the thickness is greater than necessary.

Furthermore, arranging hot plates that are thicker and heavier than necessary in multiple stages means that the upper and lower parts of the plate to be processed placed on the hot plate are This may increase the variation in the pressure applied to the treated plate, resulting in poor adhesion or thinning of the processed plate, or the diameter of the ram cylinder, which is the means for raising and lowering the hot plate at each stage, and the supply of fluid to the cylinder. This increases the capacity and burden on the fluid pressure unit, forcing multi-stage presses to become larger.

"Means for Solving the Problems" In view of the above, the present invention provides a vertical multi-stage press in which a plurality of heat plates are arranged on the upper and lower sides. This is a horizontal multi-stage press that suspends plates or elastically supports them at four points, and has a central frame that supports the upper and lower cross beams.

Further, in the above embodiment based on FIGS. 1 to 5, the hot plate 10 and the left and right movable plates 11 and 12 are suspended from the rail 6 of the upper cross beam 1. Lower crossbeam 2
A rail 6' is also laid, and at least one of the upper and lower parts of the upper and lower rails 6゜6' is slidably supported along the upper cross beam 1 or the lower cross beam 2, and the movable member 9 Another embodiment will be described in which the four points of the hot plate 10 and the left and right movable plates 11 and 12 are elastically supported by elastically mounting the apparatus.

Note that parts that have already been explained will be given the same numbers and will not be explained in detail.

In Figures 6 to 8, the lower rail 6' is the lower crossbeam 2.
It is slidable along the guide surface 37 of the lower cross beam 2 and the lower surface of the lower rail 6'.
8 are mounted facing each other, and a spring member 39 is fixedly connected between the fittings 38 to push up the lower rail 6' with a constant pressure under normal conditions.

Conversely, although not shown, spring members are attached to the lower surface of the upper cross beam l and the upper surface of the upper rail so that the upper rail 6 can freely slide along the guide surface of the upper cross beam 1. It is also possible to change the biasing force applied to the member 39 to fluid pressure or the like.

"action" Next, the effect will be explained.

First, by operating the fluid cylinders 13 and 14, the ram 15
When ゜16 is reduced, the left and right movable plates 11, 12 and the heating plates 10 of each stage are suspended between the upper cross beams 1 by the moving member 9, and are held together by the engagement part of the ruler 7 and the engagement part 8. It moves along the rail 6 while the side is held.

At this time, as shown in FIGS. 6 to 8, if the four points are elastically supported, and if the lower rail 6' is pushed up from above the lower cross beam 2, substantially each step hot plate 10,
When the left and right movable plates n and 12 are suspended from above the upper cross beam 1, and conversely, when the upper rail 6 is pushed down from the upper cross beam 1, the hot plate 10, The left and right movable plates 11 and 12 are placed on the lower cross beam 2. In either case, the movable member 9 is elastically restrained by the rails 6, 6' at the four points of the hot plate 10, left and right movable plates 1.1 and 12, and rolls smoothly. .

During this movement, the heating plates 10 of each stage located on the left half and the heating plates 10 of each stage located on the right half with the central frame 5 as a boundary.
synchronously or individually, the free ends of the restrictors 36 and the brackets 35 successively come into contact with each other at the four corners of the fixed hot plates 10 attached to both sides of the central frame 5, By regulating the maximum opening, the left-right spacing of the hot plates IO in each stage is maintained evenly, and the press is in an open state.

Next, the plate 17 to be processed is carried from a loader located on the carry-in side between the hot plates 10 in each stage, where a heating medium is supplied and maintained at a required temperature. The loaded plate 17 to be processed is supported at its lower end by the drive of the left and right conveyors 31.3.2, and is conveyed to the center position in the front-rear direction of the hot plate 1o of each stage, and is stopped at that position. .

Note that if the dimensions of the plates 17 to be processed are different between the hot plate 10 located on the left half and the hot plate 10 located on the right half with the central frame 5 as the boundary, Then, adjust the positions of the fluid cylinders 13 and 14, respectively.

For example, the plate body 17 to be processed located in the left half has the dimensions shown in the left half of FIG. 4, and the plate body 17 to be processed located in the right half has the dimensions shown in the right half of FIG. In this case, since the dimensions differ only in the vertical direction, the step feed screw 23
The vertical position of each fluid cylinder 13, 14 is adjusted by fitting and sliding the sliding plate 19 on the sliding guide 18. Also, adjust the ram 19 in the same way,
Furthermore, compared to the plate 17 to be processed carried between the hot plates 10 in each stage of the left half, as shown in the right half of FIG. 5, for example, each stage of the right half When the vertical and horizontal dimensions of the plate 17 to be processed to be carried between the hot plates 10 are proportionally reduced, in addition to moving vertically, the fluid cylinders 13, 14, and rams 15, 16 are integrally moved horizontally as well. It is to be moved to. That is, screw pestle 2
5, the pair of moving pieces 26 approach each other on each reverse screw, so each fluid cylinder 13,
14 approaches the notch of the sliding plate 19 by the same distance along the vertical sliding guide 24, and adjusts its position according to the reduced size of the plate 17 to be processed. Also, Ram 15, 16
will also be adjusted in sync with this.

The plate 17 to be processed is carried by the left and right conveyors 31 and 32 to the center position between the hot plates 10 of each stage located on the left and right halves, and is stopped.
, 32, the left and right push-up bodies 33 ,
34 into the notch groove 3 through screw movement, crank movement, fluid movement, etc.
By protruding into the 0, its lower end is lifted as shown in FIGS. 4, 5, and 8.

Therefore, the plate body 17 to be processed is heated by the hot plate 10 even in the vertical direction.
In this state, each fluid cylinder 13, 1
When the rams 15 and 16 are extended by the operation of 4, the moving members 9 on both upper and lower sides move along the rails 6 and 6'.
By moving along the left and right movable plates 11 and 1
2 is in a press closed state without pushing the heat plates 10 of each stage into which the plate bodies I7 to be processed are inserted from both sides thereof to the heat plates 10 on both sides of the central frame 5.

After the press is closed, each plate 17 to be processed is heated and pressurized by the heating action of the hot plate 10 and the pressurizing action of each fluid cylinder 13 and 14. The hot plate 10 of each stage is suspended from both sides of the top. It is supported elastically at the top and bottom four points, so
The pressure applied to the plate 17 to be processed is equal to each stage.

After heating and pressurizing, the left and right push-up bodies 33, 3 = 1 are inserted into the notch groove 30 again, and the rams 1.5, 16 are contracted by the operation of the fluid cylinders 13, 14, and the press is opened. Then, the left and right push-up bodies 33 and 34 are recessed below the conveyance surface, and the processing plate body is moved onto the left and right conveyors 31.3.
2 and transported to the unloader side.

Note that if the dimensions and thicknesses of the plates 17 to be processed that are carried into the left half and right half of the center frame 5 as a boundary are different, and the heating and pressurizing times are different, the above-mentioned carrying out operation is performed individually. It turns out.

"Effects" As described above, according to the present invention, the frames are installed on the left and right sides via a pair of upper and lower cross beams arranged at arbitrary intervals, and the central frame supports the upper and lower cross beams between the left and right frames. erected, and a plurality of heat plates and left and right movable plates are suspended between each frame on the rails laid on the upper cross beam or the upper and lower cross beams via movable members, or the four points are supported elastically. The rams of the fluid cylinders installed on the left and right frames are attached to the back of each movable platen so as to be movable in the left and right direction, and a press is opened near the four corners of the adjacent hot plate and the left and right movable platens. A regulating device is installed to maintain an even spacing between the hot plates during heating, and a conveyor is installed below the hot plates to convey, support, and unload the plates. The thickness of the hot plate can be appropriate based on strength, and the hot plate can be made lightweight, making it possible to downsize the entire device.

In particular, since the upper and lower cross beams are generally supported at their central portions by the central frame, even if the number of hot plates increases, deflection and bending stress can be avoided and the structure can be simplified.

Furthermore, if each fluid cylinder and each ram can be integrally moved in a vertical plane along sliding guides attached to the left and right frames and left and right movable plates, each of the left half of the The dimensions, thickness, etc. of the plate to be processed carried between the hot plates of the tiers and the plate to be treated carried between the hot plates of each tier on the right half can be different, and when heating and pressurizing. The left and right sides can also be operated synchronously or separately.
