<Explanation of the operating state when the door is raised>
In this embodiment, the state of FIG. 1, FIG. 3 (a), and FIG. 3 (b) maintains the airtight state inside the dryer 1 by the door main body 10 pressing the opening part of the dryer 1. FIG. This state is referred to as “the door body 10 is present at the closed position”. And when opening the opening part of the dryer 1, the upward movement of the door main body 10 is started from this obstruction | occlusion position.

  When the upward movement of the door body 10 is started, first, in the state shown in FIG. 3B, a lift switch (not shown) provided in the control panel 18 is turned on (turned on). Then, the solenoid 45 is excited, and the door drop prevention fitting 51 is pulled toward the solenoid 45 (see FIG. 8B). At this time, it is confirmed that the door main body 10 can be raised by the limit switch jig 46 pushing up the lever of the limit switch 44.

  Next, simultaneously with the above confirmation, the motor 3 (see FIG. 2) starts to rotate (for example, clockwise).

  The motor 3 and the lower door 11 constituting the door body 10 are connected by a wire 21. Specifically, via a V pulley 22, a wire 21, a V idler 20, and a wire support jig 27, The driving force of the motor 3 is configured to be transmitted to the lower door 11.

In the present embodiment, the attached bearing roller 26 is provided in the vicinity of the wire supporting jig 27. When the door main body 10 (the lower door 11 and the upper door 12) is moved up and down by a single guarded motor 3 with a brake, the upper door 12 moves laterally at the start of the ascending operation and immediately before the end of the descending operation. Therefore, in the present embodiment, this attached bearing roller 26 is provided to prevent the upper door 12 and the lower door 11 from being rubbed during the lateral movement.
Further, in the present embodiment, a rail guide / upper cover 23 and a rail guide / lower cover 24 are provided which cover the wire 21 and function as a rail guide when the door body 10 moves.

Now, since the motor 3 and the lower door 11 are connected as described above, when the rotational driving of the motor 3 is started, the lower door 11 constituting the door main body 10 is moved along the guide frame body 2 into the container. After separating from the opening, it begins to rise substantially parallel to the opening.
Specifically, the lower door 11 starts moving by the motor 3 and is separated from the container opening through the first guide portions 2C and 2D of the guide frame 2 corresponding to the lower door 11 (FIGS. 3 and 3). 4 etc.). That is, the bearings 30C and 30D provided on the lower door 11 move to the upper right (see FIG. 4 and the like) along the first guide portions 2C and 2D, and the lower door 11 also moves to the upper right along with the bearings 30C and 30D. Therefore, the heat-insulating packing 41 (see FIG. 7 and the like) provided in the container opening and the lower door 11 are not rubbed against each other (the lower door 11 is against the heat-insulating packing 41). Will not slide).

  The lower door 11 separated from the container opening is then moved upward substantially parallel to the container opening by the bearings 30C and 30D moving along the lower door upper rail guide 35 and the lower door lower rail guide 38. Moving. That is, it moves upward substantially parallel to the container opening via the second guide portions 2G and 2H corresponding to the lower door 11.

When the lower door 11 rises for a while (for example, 5 to 6 seconds), the attached bearing roller 26 provided at the upper end of the lower door 11 is moved to the upper door lifting jig provided at the upper end of the upper door 12. 25 is contacted. Then, as the lower door 11 rises, the upper door 12 also starts moving.
Specifically, the driving force of the motor 3 is transmitted from the lower door 11 to the upper door 12 via the upper door lifting jig 25, and the upper door 12 is guided to the first guide frame 2 corresponding to the upper door 12. It is separated from the container opening through the parts 2A and 2B (see FIGS. 3 and 4). That is, the bearings 30A and 30B provided on the upper door 12 move to the upper right (see FIG. 4 and the like) along the first guide portions 2A and 2B, and the upper door 12 also moves to the upper right along with the bearings 30A and 30B. Therefore, the heat insulating packing 41 (see FIG. 7 and the like) provided in the container opening and the upper door 12 are not rubbed against each other (the upper door 12 is not in contact with the heat insulating packing 41). Will not slide).

  The upper door 12 separated from the container opening is then moved upward substantially parallel to the container opening by moving the bearings 30A and 30B along the upper door upper rail guide 31 and the upper door lower rail guide 34. Moving. That is, it moves upward substantially parallel to the container opening via the second guide portions 2E and 2F corresponding to the upper door 12.

However, in the present embodiment, a lower door through jig 36 is provided on the upper part of the dropping jig 37. Therefore, in this embodiment, when the bearing 30D passes through the dropping jig 37, the lower door 11 is held by the lower door through jig 36, and therefore the bearing 30D is not dropped into a different guide portion. Absent.

  When the lower door 11 continues to descend while the lower door 11 is held by the lower door through jig 36, the bearing 30 </ b> C provided on the upper side of the lower door 11 moves down to the first guide portion 2 </ b> C having the dropping jig 37. The bearing 30D provided on the lower side of the lower door 11 comes into contact with the first guide portion 2D having the dropping jig 39, and the lower door 11 moves along the first guide portions 2C and 2D along with the dryer. 1 is pressed into a position where it is closed by pressing (see FIG. 3B).

  As described above, when the bearing 30 </ b> D provided on the lower side of the lower door 11 comes into contact with the first guide portion 2 </ b> D having the dropping jig 39 and is dropped to the opening side of the dryer 1, the lower end of the lower door 11 is placed. 1 is pressed by the lower limit switch 28 shown in FIG. 1, and the rotation drive of the motor 3 is stopped based on a signal from the lower limit switch 28. Then, after confirming that the motor 3 has stopped rotating, the solenoid 45 is demagnetized, and the door drop prevention fitting 51 is moved to the left side by the urging force of the spring 48 and stopped (see FIG. 8B, etc.). ).

  Until the operation of the door drop prevention metal fitting 51 is stopped, the door main body 10 is lowered.
