Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a plurality of heating plates arranged between frames arranged oppositely on the left and right so that they can be opened and closed, and a plate to be treated such as plywood, decorative board, or veneer veneer is processed. The present invention relates to a method and apparatus for smoothly taking out a processed plate interposed between hot plates after being heated and pressed onto a conveyor in a horizontal multi-stage press that heats and presses.

Normally, the multistage press that is mainly used 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 inserting and placing the plate body in between, raise the movable plate by 2 degrees and push up the heating plates in sequence starting from the lowest heating plate (L7) and press the press close button (-). The treated plate was heated to 1 tE for a period of 11.1 minutes and then heated to 1000 ml.

However, when using this multi-stage fresco that supports multiple heating plates with the upper sea lion, support claws are attached to the four corners of the upper sea lion to support each heating plate. Installation, this support 1
．． A method is adopted in which one claw is placed in turn on a support in the form of a ladder step. Therefore, when determining the thickness of the hot plate at each step, the main objective is to place the plate to be processed. In addition to the strength required for heating and pressurizing, we also take into account the strength required to cope with the deflection and bending caused by the distance between the supporting points, and in order to provide rigidity, By arranging hot plates having the above thickness and weight in multiple stages, it is necessary to apply the processing at the upper and lower parts of the plate to be processed placed on the hot plate. Not only does pressure variation increase, resulting in poor adhesion and thinning of the treated plate, but also the ram/
The cylinder diameter, the pump capacity for supplying fluid to the cylinder, the fluid ratio increased the load on the unit, required one person, required a lot of noise, and forced the multi-stage press to be larger.

1. Vertical multi-stage press with multiple heat plates arranged below. By arranging hot plates side by side in the left and right direction and using a horizontal multi-stage press, we can solve the problem of variation in pressure force. Attempts have been made to eliminate poor adhesion, make the hot plate lighter (1" L), or downsize the fluid pressure unit, but due to the following reasons, they have not yet been put into practical use.

That is, in a vertical multistage press, the rear end of the plate to be processed is transported by a presser inserted between the hot plates, and placed on the hot plate over a medium heat. The treated plate is opened from approximately the center of the hot plate.
At the take-out 17 position 1 on the data side, it is pushed by Jinosha. Therefore, the plate L1 to be treated is always in a position suitable for heating and pressing, and during heating and pressing, it is possible that the wood resin present in the plate or the adhesive applied to the plate may be removed. Even if the treated plate is in close contact with the hot plate,
Furthermore, when the plate to be heated and pressurized is thin,
After heating and pressurizing, it warps more easily than thicker materials, resulting in clogging between the hot plates, but the pushing action of Puno/Ya releases the tight state and the clogging.

However, in the Inno 4 type multi-stage press, the lower end of the plate to be processed protrudes outside the hot plate, so it cannot enjoy extreme heating and pressure, and the above-mentioned close contact state If a blockage occurred, the treated plate could not be removed from the hot plate.

In view of the paper, the present invention is based on a horizontal multi-stage press consisting of a plurality of rows of hot plates that can be opened and closed at equal distances between frames arranged oppositely on the left and right sides, in an open state after heating and pressurizing. The pushing bodies are inserted between the hot plates by lowering the connecting beams, and the treated plates interposed between the hot plates are pushed down. The embodiment will be explained from the configuration based on the drawings.

Frames 3 and 4 are installed on the left and right through a pair of upper and lower cross beams 1 and 2 arranged at arbitrary intervals in the vertical direction and the front and rear directions, and rails 5 are laid on the upper cross beams 1.
Attach the ruler 6 to one of them. Between the rails 5, a retaining portion 7 that engages at a constant Ill D kC is disposed on either one of the rails. A hot plate 9 and a movable platen 10 are suspended.

A plurality of fluid/linders 11 are installed on the one frame 3, and the tip of the ram 12 is attached to the back of the moving plate, and the hot plate 9 and the moving plate are moved in the right direction. I am free to do so.

Next, the hot plate 9 has a supply port 13 at the top for supplying and discharging a heating medium such as hot oil or steam to a passage formed inside the hot plate 9.
A discharge D 111 is installed at the bottom, and 1... and the loading of the plate 15 to be processed 11! i1111 located in l
i/+i K forms an insertion kite 1 (+) whose cross section is approximately triangular.

In addition, the left and right sides of the hot plate 9 and the movable plate 10 -l: FiτIS
Alternatively, as shown in the figure, the brackets 17 are respectively attached to the upper and lower sides, that is, near the four corners that do not impede the loading and unloading of the plate to be processed I5, and a gate-shaped regulating device 18 is installed between these adjacent brackets 17. They cross-linked each other 7 and attached their ends to Praknod 17, and the other Korea; Free State 11 and 1 ~
, When the press is opened, the free tube Hj5 of the restrictor 18 is fixed;
Maintaining the spacing between lo and left side h is even. ○ Next 1) Drill a pair of one-notch grooves 19 at intervals at the bottom of the il heating plate 9, and below the , the processed plate 15 is carried in and supported, and the processed plate 2 is heated and pressurized.
A conveyor 21 consisting of a plurality of rolls that carries out 0
is arranged between the machine frames 22 on the lower cross beam 2.

Further, a pair of push-up bodies 23 are inserted into the pair of cutout grooves 19 and have a length approximately corresponding to the length of the hot plates 9 of all stages when the press is opened, so that they can freely move in and out of the conveyor surface of the conveyor 21. , a screw movement, a rack and pinion movement, a fluid movement, or a crank lever one type using a fluid movement as shown in the figure. Specifically, the support frame 24i1' horizontally suspended between the lower cross beams 2 is fixed to the hydraulic nolinder 25, and one end of the VC arm 27 is pivotally supported at the tip of the piston rod 26. The other end of this arm 27 is fitted onto an actuation shaft 29 supported between the lower cross beams 2 via a bearing 28, and levers 30 are fitted onto both ends of this actuation shaft 290. 21) A pair of pushers listed in 1j 23
-30 is pivotally supported at the other end of the push-up body 23 of 1, which is pivoted to J, and regulates the elevation of the flat construction.

- Furthermore, at least one pair of connecting beams 3I, which is approximately equivalent to the length between the left and right frames 3 and 4, are arranged on the upper part of the hot plate 9 by means of a screw movement, a rack and pinion movement, a fluid movement, or the above-mentioned It is arranged so that it can be lowered by +1 using a crank lever type that utilizes fluid motion similar to the push-up body 23.

That is, the connecting Yanagawa fluid cylinders fixed to the upper surfaces of the left and right frames 3 and 4 respectively; : Pivotally supported on one end of a dogleg-shaped arm 36 that is pivotally supported on part 35. On the other hand, the other ends of the pair of arms 36 are pivoted to both ends of the two-part link 370, and the connecting beams 31 are placed on both sides between the upper links 37.
is attached. A pusher body 38 of approximately the same thickness, which is slightly narrower than the spacing between the hot plates 9 when the press is opened, is attached to the longitudinal direction of each connecting beam 31, and the push bodies 38 are attached to the top surface of the hot plates 9 at each stage. Three guide plates are attached to the body 38 approach path.

Next, the effect will be explained.

When the fluid cylinder 11 is actuated to reduce the ram 12, the movable platen 10 and the heat plates 9 of each stage are moved between the upper cross beams 1 by the moving member 8, and by the engagement part between the ruler 6 and the engagement part 7. It moves to the left in the figure along the rail 5vc while one side is kept parallel. At this speed of movement, the free end of the regulating tool 18 moves from the hot plate 9 located at the right end to the four corners of the hot plate 9.
By contacting the brackets 17 of adjacent hot plates 9 and successively restricting their maximum opening, the left and right spacing between the hot plates 9 of each stage is maintained evenly, and the press is in an open state.

Next, the plates 15 to be processed are carried in all at once from a loader located on the carry-in side between the hot plates 9 of each stage, which are maintained at a required temperature by being supplied with a heating medium. The loaded plate 15 to be processed is supported at its lower end by the drive of the conveyor 21, and is conveyed to the center position in the front-rear direction of the hot plates 9 of each stage, and stopped at that position.

At this time, the rotation of the cylinder 25,
When the piston rod 2G is extended, the operation 1101
+ 2'l is rotated in the counter-time direction in Figure 4, so
1 body 2 that was buried under the transport surface of the transport conveyor 21
3 protrudes from the conveying surface via a pair of levers 30 7;
Holding the lower ends of the plates 5 to be processed which are supported in parallel on the conveyor 21, lower the hot plate 9 11;
As shown in the left half of Figure 3 or the dotted chain line in Figure 4, the mechanism intervenes in the notched groove 19. ) Therefore, the plate 15 to be processed reaches inside the hot plate 9 in the vertical direction as well, and in this state, if the ram 12 is extended by the operation of the fluid/linda 11, the press is closed, contrary to the above-mentioned item-1. However, the plate 15 to be processed is heated and pressurized.

After heating and pressurizing, when the fluid cylinder 11 is actuated to open the press, the push-up body 23 is temporarily immersed into the conveying surface t' by the reverse operation of the push-up fluid/cylinder 25.

Next, when the connected Yanagawa fluid cylinder 32 is operated to extend the piston rod 33, the arm 36 is brought into contact with the pin 35.
It swings down using the part as a fulcrum, and the series A: 1'i beam 3+i1-
No. 3 reaches the lowering limit as shown in FIG. 4.

In this case, as shown in FIGS. 5 and 6, 11
Then, they are pushed down by a pusher (38) which descends without being regulated by the guide plate 39, and are transferred to the transport conveyor 21, where they are carried out all at once.

After the operation, the press body 38 moves up the connecting beam 31 to reach the standby position at the upper limit, and one press cycle is completed L7. According to the present invention, in a horizontal multi-stage press in which a plurality of hot plates that can be opened and closed are arranged in parallel at equal intervals between left and right frames, the hot plates are spaced apart when the press is opened. A connecting beam to which a pusher is attached is provided at an appropriate position above each tier of heating plates, and the connecting beam is lowered between each tier of heating plates in an open state after heating and pressurizing, thereby allowing each pusher to pass through the connecting beam. Since the treated board interposed between the hot plates is pushed down, the wood resin present in the board to be treated or the wood resin that has been applied to the board to be treated is removed during heating. Even if the treated plate is in close contact with the hot plate due to leakage of the adhesive onto the hot plate, the close contact is easily released by pressing down the pusher.

In addition, as shown in Fig. 5, even if the processed plate is interposed between the hot plates and does not fall freely due to warping that is easy to occur in a particularly thin treated plate, as shown in Fig. 6. like,
The lower end of the treated plate completely protrudes outside the hot plate and is pushed down by a pusher, so smooth removal can be expected.
