Description

Detailed Description of the Invention "Field of Industrial Application" The present invention is applied to a horizontal multistage press in which plate bodies such as plywood, decorative boards, or veneer veneers are arranged side by side at equal intervals when the press is opened. This relates to a device that transports plates all at once between hot plates or heats and presses them when the press is closed, and takes them out all at once when the press is opened. A press 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, and the plate to be processed is inserted between these hot plates. After that, the movable platen was raised, and the hot plates above were successively pushed up starting from the lowest hot plate, the press was closed, and the treated plate was heated and pressurized for the required time.

However, in this type of multi-stage press having multiple upper and lower heating plates, when supporting each stage of heating plates,
A method is adopted in which support claws are attached to the four corners, and these support claws are sequentially placed on ladder-like supports attached to pillars. Therefore, when determining the thickness of the heating plate at each stage,
In addition to the strength required to heat and press the plate, which is the main purpose, the thickness is greater than necessary to provide rigidity in consideration of the strength required to cope with bending and deflection caused by the distance between the fulcrums.

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 Not only does this increase the variation in pressure applied to the processed plate, resulting in poor adhesion and reduced thickness, but also the diameter of the ram cylinder, which is the means for raising and lowering the hot plates at each stage, and the supply of fluid to the cylinder. This caused an increase in the pump capacity and the burden on the fluid pressure unit, forcing the multistage press to become larger.

For this reason, by adopting a horizontal multi-stage press in which hot plates are arranged side by side in contrast to a multi-stage press in which multiple hot plates are arranged above and below, the pressure applied to the processed plate after heating and pressing can be reduced. Attempts have been made to correct the variations, reduce the weight of the hot plate, or downsize the fluid pressure unit. In parallel, the plate to be processed was conveyed in an upright position between the hot plates of a horizontal multi-stage press, which were arranged side by side at equal intervals when the press was opened, or the processed plate was conveyed in an upright position. A device is required to carry it out.

Conventionally, this type of device for controlling the conveyance by standing up a plate has a plurality of forks fixed between a pair of chain conveyors perpendicular to the conveyance direction, and a plate is interposed between these forks. There was one in which the two lower ends were supported by the link chains of a pair of chain conveyors, and the conveyance was carried out according to the circumferential speed of the chain conveyors.

However, if the chain conveyor is continuously rotated due to the meshing of the chain wheel and link chain, each link chain will wear out, and when the chain wheel returns to rotation, the meshing condition with the chain wheel will deteriorate, causing the chain conveyor to become In order to create an endless track, the slight clearance set between the link chains has to be further expanded, causing the chain conveyor to flex and the spacing between the forks fixed to the link chains to be thrown out of alignment.

As a result, during the upright transportation of the board, the upper part of each of the seven orcs collided with the board, or the bottom of the board got caught in the expanded clearance, resulting in damage to the board. .

In particular, this type of fork, in which the plate body is interposed in a freely undulating manner, has its lower end simply supported by a link chain with a small support teeth compared to the length of the 7 oak, and when standing up, Since there is no special means for holding adjacent forks at equal intervals, the upper free ends of the forks tend to deviate from the upright position even under normal conditions, and as described above, If the chain conveyor is bent, the above-mentioned disadvantages will be exacerbated.

However, if the entire fork cannot be properly regulated in straightness, if the upright plates to be processed are simultaneously carried between the seven hot plates of a horizontal multi-stage press, the hot plate If the plate to be treated collides with the side of the fork, or conversely, when carrying the treated plate in an upright position between each stage of hot plates or between the shift oaks, the treated plate may collide with the side of each fork. This results in bodies colliding.

Therefore, some attempts have been made to increase the area of the link chain to firmly support the fork and to control the straightness, but if the area of the link chain increases, the distance between adjacent forks will increase proportionally, and the heat will increase. This results in a new drawback that the plate spacing does not match, or the plate body interposed between the forks swings during conveyance.

"Problems to be Solved by the Invention" In view of the limitation, the present invention has a plurality of heating plates arranged in parallel at equal intervals between frames arranged on the left and right at arbitrary intervals, and opened and closed by a movable platen. Transporting plates using a horizontal multi-stage press that can be moved freely,
In addition, the chain conveyor, which is disposed on the unloading side and supports the loader shelf that carries plates between the hot plates, or the unloader shelf that carries the plates from between the hot plates, can be moved over an arbitrary distance by a plurality of auxiliary chains.
