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 horizontal multi-stage press that heats and presses or releases the press toward an arbitrary hot plate located in the center, equidistantly approaching and separating from those located at both ends.

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 to be processed between them, the movable platen is raised, and the hot plates above are pushed up sequentially, starting with the lowest hot plate, the press is closed, and the process is completed by heating and pressurizing for the required time. I had obtained a board.

Therefore, in conventional vertical multi-stage presses, each of the closing and opening movements that make up the press cycle must depend on the elevation and descent of the movable platen located below, since multiple heating plates are arranged above and below. Therefore, it was impossible to shorten the press cycle, that is, shorten the press opening and closing time.

In addition, in this type of multi-stage press having a plurality of upper and lower heating plates, in order to support each stage of the heating plates, support claws are attached to the four corners of the heat plates, and the support claws are attached to the supports in the form of a ladder step. A method is adopted in which the components are placed one after another on a support. Therefore, when determining the thickness of the hot plate at each stage, in addition to the strength required to heat and press the plate to be processed, which is the purpose of heating, also take into consideration the strength required to handle the deflection and bending caused by the distance between the supporting points. In order to provide rigidity, it becomes thicker than necessary. Furthermore, arranging hot plates that are thicker and heavier than necessary in multiple stages means that the upper part of the plate to be processed is placed on the hot plate. , the variation in the pressing force in the lower section increases, which not only causes poor adhesion and thinning of the processed plate, but also reduces the diameter of the ram cylinder, which is the means for raising and lowering the MLGi plate, and the supply of fluid to the cylinder. This caused an increase in the pump capacity and the load on the fluid unit, forcing the multistage press to become larger.

In view of the above, the present invention has been developed to provide a
Multiple stages of hot plates are arranged in parallel via a pair of movable plates, and these movable plates are interconnected, and fluid motion is applied to each movable plate to enable them to move toward and away from each other at equal distances. Pressure is applied to the staged heating plates at equal intervals, and when the press is closed, approaching an arbitrary heating plate located in the center from both sides.The following is an example of an apparatus for directly carrying out the method of the present invention. , the configuration will be explained based on the attached drawings.

For example, as the details are shown in FIG.
A sliding plate 18 fitted between the left and right sliding guides 17 is attached to the left and right sliding guides 17.
Fluid cylinders 12; 13 are inserted at approximately equal intervals. On the other hand, a pair of left and right sliding guides is attached to the backs of the left and right movable plates 10 and 11 facing each other in the vertical direction.
It is inserted and held.

Next, after drilling holes in the vicinity of both ends of the sliding plates 18 on the left and right frames 3 and 4 sides, a female screw portion is formed in the drilled portion, and a 9-step feed screw whose upper and lower portions are held by the guide plate 21 is formed. 22 is screwed in, and the sliding plate 18 can be moved upwardly and downwardly by rotating the forwarding screw 22 in the forward and reverse directions.

In order to move the -C sliding plate 18 up and down along the left and right sliding guide 7, it is also possible to use rack and pinion movement or fluid movement means as shown in FIG. That is, a pair of vertically moving fluid cylinders 23 are pivotally supported near both ends of the sliding plate 180, and each piston rod 2
4 is pivotally supported on the left and right frames 3 and 4.

Furthermore, FIG. 6 shows a case in which -(-) is moved in the vertical plane in addition to downward movement, as well as horizontal movement.
The inside of the sliding plate 18 is cut out into a rectangular shape, and vertical sliding guides 25 having a fixed length in the horizontal direction are formed at the upper and lower parts of the sliding plate 18, and the fluid cylinder 1 is installed between the vertical sliding guides 25 via appropriate fittings.
2 and 13 are fitted and twisted, the sliding plate 18 supports screw punches 26 having reverse screws carved into each other with the center part as a boundary, and a pair of moving pieces screwed into each screw part. 27 is attached to the fittings of the fluid cylinders 12 and 13, and the fluid cylinders 12 and 13 can be moved toward and away from each other in the lateral direction by rotation of the screw 26. At this time, each of the sliding plates 20 of the rams 1, 1, and 15 has the same structure as the sliding plate 18 of the rams 1, 1, and 15, and each of the rams 1, 1, and 15 has the same configuration as the sliding plate 18 of the rams 1, 1, and 15.
4 and 15 are being followed.

Next, the hot plate 9 has a supply port 28 at the top to supply and discharge a heating medium such as hot oil or steam to the passage formed inside the hot plate 9.
A discharge port 29 is installed at each lower part, and an insertion guide 30 having a substantially triangular cross section is formed on the side surface located on the loading side of the shredded plate 16 to be processed.

Further, a pair of notch grooves 31 are bored at an arbitrary interval in the lower part of the hot plate 9, and a conveyor consisting of a plurality of rolls for carrying in, supporting, and carrying out the plate 16 to be processed is provided below the notch grooves 31. The conveyor 32 is arranged between the machine frames 33 on the lower cross beam 2. A pair of push-up bodies 34, which intervene in the pair of notched grooves 31 and have a length approximately equivalent to the length of the hot plates 9 in all stages when the press is opened, are made to be able to move in and out of the conveyance surface of the conveyor 32. .

Next, brackets are placed at the top and bottom of the left and right of the hot plate 9 and the left and right movable plates 10' and 11, or on both sides of the top and bottom as shown in the figure, near the four corners that do not interfere with the loading and unloading of the plate 16 to be processed. 35 respectively, and these adjacent brackets 3
A gate-shaped regulating device 36 is bridged between the holes 5 and 5, one end of which is attached to the bracket 35, and the other end is made a free end, and the free end of the regulating device 36 is locked to the bracket 35 when the press is opened. Plate 9 and the left and right movable plates], 0, and II are maintained at equal left and right intervals.Furthermore, there are locking tools 37 on both sides of the left and right movable plates 10, 1.1, 1, and 2. , 38 are each protruded and fixed, and both ends of a linking member 39 such as a chino, a lobe, a wire, etc. are connected between opposing connecting tools 37° and 38 on each side between the left and right movable plates 10° and 11. At the same time, the connecting member 39 is attached to either one of the frames 3 and 4, for example, the right frame 4.
They are each suspended from a rotating wheel 40 which is pivotally supported by a rotating wheel 40, and maintained in a tensioned state. Incidentally, the linking member 39 is used for carrying in the plate body 16 to be processed,
The location is not limited to the illustrated example above as long as it does not interfere with carrying out.

Next, the action will be explained.

When the left and right fluid cylinders 1.2 and 13 are operated to reduce the rams 14 and 15 without switching, the left and right movable plates]0
, 11. The hot plate 9 of each stage is suspended from the upper cross beam 1 by the moving member 8, and is moved along the rail 5 while one side is kept parallel by the engagement part of the ruler 6 and the engagement part 7. It expands and moves in the left and right directions in the figure.

During this movement, the expansion views of the left and right movable plates 10, ]] are uniformly regulated by the linking member 39, and the heating plates 9 at each stage are arranged in order from those adjacent to the left and right movable plates 10, II. The restricting tools 36 come into contact with the brackets 35 at the four corners and restrict the maximum opening thereof, thereby maintaining equal left-right spacing between the hot plates 9 at each stage and bringing the press into an open state.

Next, the plates 16 to be processed are carried in all at once from the loader located on the carry-in side between the hot plates 9 in each stage where a heating medium is supplied and maintained at the required temperature. If the dimensions of 16 are different, the pressure points are adjusted each time.

For example, as shown in FIG. 4, when one dimension of the plate 16 to be processed changes only in the vertical direction, the threading of the step feed screw 22,
Alternatively, by operating the vertical movement fluid cylinder 23, the left and right fluid cylinders 12, 13 and the rams 14, 15
Adjust the vertical position of. As shown in Figure 6, if the dimensions change proportionally in the vertical and horizontal directions,
By rotating the screw punch 26, the movable pieces 27 of each screw portion are brought into contact with and separated from each other, and the lateral positions of the left and right fluid cylinders 12, 13 and the rams 1.4, 15 are also adjusted. Adjust so that the pressure point is located in the center according to the dimensions.

After this adjustment, the processing target plate 16 is supported at its lower end by the transport conveyor 32, and is transported 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, if the push-up body 34 is projected from below the conveyance surface into the notch groove 31, the plate 16 to be processed on the conveyor 320 is lifted and inserted between the hot plates 9 in a substantially upright state.

Next, by simultaneously operating the left and right fluid cylinders 12 and 13 to extend the respective rams 14 and 1.5, the left and right movable plates 10 and 1.1 are moved between the left and right movable plates 10 and 1.1 by the linking member 39 that is linked to each other. The heating plates 9 located at the center are kept close to each other by the same amount, and the heating plates 9 at both adjacent ends are kept close to each other by the same amount.
The press is sequentially contracted and closed toward the press, and the plate 16 to be processed is heated and pressurized.

Thereafter, the press is opened as described above, and the heated and pressurized processed plate is carried out to an unloader.

As described above, according to the present invention, a plurality of heat plates are arranged in parallel between the left and right frames via a pair of movable plates, and these movable plates are interconnected, and each movable Fluid motion is applied to each plate so that they can move toward and away from each other at equal distances, and when the press is opened, the hot plates of each stage are placed at equal intervals, and when the press is closed,
Since pressurization is applied closely from both sides toward any hot plate located in the center, the press opening and closing movements that make up the press cycle are maintained evenly, and the time required for this is also halved. Therefore, the workability can be improved.

In addition, when the press is closed, the time for which the plate to be processed is left unpressurized between the hot plates of each stage is halved, which prevents the acceleration of heat curing of the adhesive and prevents the processed plate from being heated and pressed. One of the causes of poor adhesion can be avoided.

Furthermore, when heating and pressurizing, the plate to be processed receives fluid movement from both the left and right sides, so it is possible to enjoy elastic pressure that mimics the thickness and slope of each plate itself. Another cause of poor adhesion in the plate can be eliminated.
