[Detailed description of the device] [Industrial applications]

The present invention relates to a door opening / closing device for a curing room, and relates to a device for opening / closing a door in a room for curing a building material board or the like, and particularly to a door opening / closing device having a structure suitable for opening / closing a plurality of curing rooms. .

2. Description of the Related Art Building material boards and the like are designed to be put in a curing room for a certain period of time such as drying treatment, and the doors provided for entering and leaving such a curing room are opened and closed by mechanical drive. It is supposed to be done. As a general opening and closing mechanism, a double door structure door or a single door structure door is known. However, the double-opening or single-opening structure requires a lot of space for opening and closing, and when the traveling rail of the automatic machine is laid in the front part of the curing room, opening and closing is restricted. Therefore, in the conventional curing room of this type, the door is opened by pulling the door directly above, which is commonly used. The conventional door opening / closing device generally has a mechanism in which a lifting guide frame for the door is attached to the upper part of the curing room, a roller chain is connected to the door, and the door is opened / closed by a lifting motor.

[Problems to be solved by the device]

However, in the above-mentioned conventional door opening / closing device, when a plurality of curing chambers are installed, the above-mentioned opening / closing drive device must be installed in each curing chamber, and the ratio of 1: 1 with respect to the number of doors. Therefore, there is a problem that a driving device is required and the cost is increased. That is, when handling a large amount of products, multiple curing rooms are required, and each has a door opening / closing device,
The initial cost will increase. In addition, since the door has a mechanism that slides up and down vertically by a chain, the sliding resistance with the door or the packing provided on the side of the curing chamber becomes large, and the door and the chamber contact when the door is closed. Sealing on the surface becomes difficult. Therefore, when steam or the like is blown into the room for curing, there is a drawback that the thermal efficiency in the room is reduced. If both opening / closing and sealing functions are to be dealt with, a complicated pulling operation is required such as moving the door away from the curing room and then pulling it upward, which causes a problem that the cost of the apparatus further increases. . The purpose of this invention is to eliminate the drawbacks of the prior art described above.
It is an object of the present invention to provide a curing room door opening / closing device capable of opening / closing a plurality of doors by a simple door opening / closing device without impairing the sealing function.

[Means for Solving the Problems]

In order to achieve the above object, a curing room door opening and closing device according to the present invention is provided with a hanging piece at an upper edge of each door in a plurality of curing rooms, and a traveling rail disposed in parallel with an upper portion of each door. To make the door opening / closing device main body movable.
The door opening / closing device main body is provided with a knock pin capable of engaging with the hanging piece at a door position of each curing room, and a swivel drive unit for swiveling the knock pin around an axis parallel to the door surface. And

[Action]

According to the above configuration, the door opening / closing device body is moved along the traveling rail just above the predetermined curing chamber, and then the knock pin is turned by the turning drive unit to correspond to the hanging piece of the door. Then, after the door is hooked with a knock pin, the turning drive unit is reversely rotated to separate the door from the curing room to open the door, and the hooked door can be moved to another room along the traveling rail. . Then, the knock pin can be turned at a predetermined position to temporarily place the door. Thereby, a plurality of doors can be freely opened and closed by one opening / closing device body. Further, since the contact surface between the door and the chamber is brought into contact with and separated from the contact surface by the circular arc interlocking motion of the swivel drive unit, forced sliding is not lost and the sealing property is not impaired. Also,
The seal can be configured to hang the door on a hook and seal by its own weight.

Hereinafter, a specific embodiment of a curing room door opening / closing device according to the present invention will be described in detail with reference to the drawings. 1 and 2 are a front view and a side view of a curing room door opening / closing device according to an embodiment of the present invention. This curing room switchgear has one switchgear body 10,
This allows you to open and close the doors 14 of multiple curing rooms 12,
It is configured so that it can move in parallel along the door line of the curing room 12 attached to it. In the embodiment, each door 14 of a plurality of curing rooms 12
An upper edge is arranged along a straight line, and a pair of parallel traveling rails 16 made of I-shaped steel is located above the straight edge. One I-shaped steel is arranged directly above the door wire, and the other I-shaped steel is arranged in front of the door 14 at a certain distance. And between such a running rail 16 and the door 14,
The opening / closing device body 10 is suspended and supported at the center of the rail 16 via traveling wheels 18, and can be moved along the laying direction of the traveling rail 16, that is, along the door line. The door 14 of each curing chamber 12 is opened and closed by such an opening / closing device body 10. First, the door 14 is engaged and supported by hooks 20 provided on the upper and lower portions of both side surfaces of the curing chamber 12, and tightening means not shown. Thus, the opening of the curing room 12 is tightly closed. Then, the opening / closing device main body 10 lifts the door 14 engaged with the hook to bring the door 14 into and out of contact with the opening of the curing chamber 12 for opening and closing. For this reason, hanging pieces 22 are erected at both ends of the upper edge of each door 14 so as not to interfere with the traveling of the opening / closing device body 10. This pair of hanging pieces
A pin hole 24 is formed at the same height position in 22 and serves as an engaging portion with the switchgear body 10. On the other hand, a swivel shaft 26 projects from the front and rear surfaces in the traveling direction of the switchgear body 10, and is driven to rotate about an axis along the traveling line by a built-in drive means.
Further, an arm 28 is integrally provided on each of the swivel shafts 26 so as to be orthogonal to the axis of rotation of the swivel shafts 26, so that the swivel motion is performed as the swivel shafts 26 rotate. The tip of this arm 28 is a door
