Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing a press board from between open hot plates.

[0002]

2. Description of the Related Art Press boards are manufactured by pressing fibers, wood chips and the like. A press board manufactured by pressing fibers is used as insulating paper for electric equipment such as a transformer. Press boards manufactured by pressing wood are
Used for building as particle board.

A press board is manufactured by pressing with a hot plate. For example, a press board used for insulating paper is manufactured by carrying a fiber material having a high moisture content between hot plates by a conveyor or the like, and pressing the hot plate for several hours or more. Fibers having a high moisture content pressed by a hot plate are heated to remove moisture, and pressed to be formed into a high-density plate shape.

[0004] A press board pressed by a hot plate is conveyed on a coal plate for removal from the hot plate. The coal plate is loaded with raw materials before being pressed and is carried into a hot plate.
After pressing, the call board is pulled out and the press board is carried out. With this apparatus, the press board can be reliably taken out from between the hot plates by placing it on the coal plate.

[0005] However, this apparatus has a drawback that the running cost is high because a considerable number of coal plates are used. It is necessary to use about 30 coal plates in, for example, a hot plate press apparatus having 10 stages. This is because it is necessary for the transfer of the raw material carried into the hot plate, the transfer between the hot plates, and the transfer of the press board carried out of the hot plate. Furthermore, since the service life of coal plates is one year or less,
Frequent replacement is required, which increases running costs. Furthermore, in an apparatus for manufacturing insulating paper,
Inexpensive iron plates cannot be used for coal plates. This is because iron powder or the like may be mixed into the press board and reduce the insulating properties of the insulating paper. For this reason, it is necessary to use an expensive stainless steel plate for the coal plate.

[0006] In order to solve such a drawback, an apparatus for removing a press board from between hot plates without using a coal plate has been developed. The device comprises a suction cup which is carried between open hotplates. The suction cup penetrates into the opened hot plate, sucks the upper surface of the press board, and draws out the sucked press board from between the hot plates.

[0007]

An apparatus in which a sucker sucks a press board and removes it from a hot plate does not need to use a large number of coal plates. Therefore, there is a feature that the running cost can be considerably reduced. However, this device has a disadvantage that it is difficult to reliably remove the press board from between the hot plates. For example, if a part of the press board is caught on a hot plate or the like, the suction cup may be peeled off from the press board and may not be taken out reliably. A press board used for insulating paper or the like is pressed by laying a net on a hot plate. This is because a net is provided with a gap between the hot plate and the press board to efficiently remove moisture. A press board placed on a net is more likely to be caught by a press board than a flat hot plate, and may not be reliably taken out.

[0008] The present invention has been developed for the purpose of further solving this drawback. An important object of the present invention is to provide a press board removal device capable of reliably removing a press board from a hot plate without using a coal plate.

[0009]

According to the present invention, there is provided a press board take-out apparatus having the following configuration to achieve the above object. The take-out device is an improved device that sucks the upper surface of the press board 2 pressed by the hot plate 1 with the suction cup 3 and takes it out from between the opened hot plates 1, and is located below the suction cup 3. , A chucking plate 4 that advances toward the suction cup 3 is provided.

Move forward towards. Chucking plate 4 to move forward
Is moved to the lower surface of the press board 2. The press board 2 includes a chucking plate 4 on the lower surface and a suction cup 3 on the upper surface.
And is taken out from between the opened hot plates 1.

In the press board take-out apparatus of the present invention, the press board 2 is placed on the chucking plate 4, the press board 2 is sandwiched between the chucking plate 4 and the suction cup 3, and the press board 2 is taken out from the hot plate 1. The press board 2 can be taken out more reliably than a conventional apparatus in which the suction cup 3 sucks the upper surface. Further, since the chucking plate 4 is inserted into the lower surface of the press board 2 adsorbed by the suction cups 3 and the press board 2 is mounted on the chucking plate 4 and transferred, the press board 2 can be used without using a large number of coal plates. 2 can be taken out of the hot plate 1 without fail.
