2. Description of the Related Art FIG. 7 is a perspective view showing a state in which a door is opened in a conventional automatic dyeing machine, and FIG. 8 is a perspective view showing a state in which the door is closed in this dyeing machine.

Automatic dyeing machines use chemicals such as xylene and alcohol, and in order to avoid the danger of inhalation of these gases by workers, doors are provided to close the cabinet of the dyeing machine almost completely, and the automatic dyeing operation is performed. It is made to do it in a way. This door is openable and closable for exchanging chemicals, getting in and out of dyed baskets, and the like.

FIGS. 7 and 8 show an automatic dyeing machine made based on such a demand. In both figures, the cabinet 1 is formed in a box shape with a front opening by a side plate 2, 2, a back plate 3, a top plate 4, and a lower plate 5, and is provided with a door 6 for opening and closing this opening. An upper plate 7 is provided in a cabinet shape in the cabinet 1, and a washing container 8 and a chemical container 9 are arranged on the lower plate 5 and the upper plate 7. Reference numeral 10 denotes a driving column, which is moved left and right along a rail 17 by a control device housed in a controller room 11, and a lifting arm 27 (FIG. 8) attached to the driving column is moved up and down. The suspended dyeing basket (not shown) is sequentially immersed in the washing container 8 and the chemical solution container 9 to stain the slide glass sample contained in the dyeing basket. 12 is a passage for moving the dyeing basket below the upper plate 7 and immersing the dyeing basket in each container on the lower plate;
Reference numeral 13 denotes a nozzle for supplying water to the washing container 8, and reference numeral 14 denotes a water supply manifold for supplying water to the nozzle. Door 6
The arm piece 15 attached to the side end is pivotally attached to the side plate 2 by the shaft 16 to close the opening of the cabinet 1 as shown in FIG.
Then, the cabinet is opened by moving it on the cabinet 1 as shown in FIG. 1 so that operations such as replenishment of a chemical solution, attachment and removal of a dye basket, and the like can be performed.

In addition to the configuration of the above-mentioned conventional example, a door such as an upward opening type, a double door opening type, or a sliding door type can be considered as an opening / closing means for preventing the front opening of the cabinet. However, these opening and closing methods have the following disadvantages.

[0006]

The top-opening door is provided with a hinge at the upper end of the opening to suspend the door and close the opening. At the time of opening, the door is flipped up to open the opening. It is necessary that there is a space only at the height of the door, and a sufficient space is required in front of the cabinet, so that a three-dimensionally large space is required to install the dyeing machine. That is, the installation location is restricted.

[0007] The double-door type door requires a place where the door can rotate in front and side of the cabinet, and similarly requires a large installation space.

Since the door of the automatic dyeing apparatus shown in FIGS. 7 and 8 overlaps the cabinet when it is opened, the height of the door is slightly increased when it is opened. Must be as large as this can be, since it will be higher than the top of the cabinet. Also, instead of being able to move up and down arbitrarily, there is a danger that the door will fall suddenly if you relax your hand when the door is in an inclined state.

A sliding door has the inconvenience that the opening is closed by a plurality of sliding doors, and when opened, a part of the opening is closed due to the overlapping of the sliding doors, and the entire opening cannot be opened. In order to open all the openings, the sliding door has to be drawn out to the side of the cabinet, which also limits the installation space.

[0010]

According to the present invention, a support bracket is pivotally attached to an upper end of an opening of a cabinet by a plate butterfly plate,
While making the door with the concave cabinet side movable along the support bracket, the support bracket and the door are
The door is connected to the door with a spring that provides elasticity to the support bracket, the arm protruding along the side plate of the door is bent out of the support bracket, and a gas damper that presses the arm between the arm and the cabinet is interposed. An object of the present invention is to solve the above problems by obtaining a door device of an automatic dyeing machine mounted thereon.

[0011]

The door is always pulled toward the support bracket due to the spring, so that the lower end of the door approaches the support bracket.

Further, the support fitting is pushed by the arm portion due to the gas damper, and presses the door in the closing direction when closing the opening of the cabinet, and applies a pushing force to the door when opening the opening.

Therefore, the door does not drop suddenly,
The door can be freely opened and closed even if there is little room in the space above and on the cabinet.

[0014]

1 to 6 show an embodiment of the present invention. FIG. 1 is a schematic perspective view showing a relationship between a door and a support fitting, and FIG. 2 is an enlarged view of AA in FIG. FIG. 3 to FIG. 6 are schematic side views showing steps of opening the door. 7 and 8 are denoted by the same reference numerals, and description thereof will be omitted.

The support fitting 26 is attached to the back of the top plate 4 above the opening of the cabinet 1 by the plate hinge 18. The plate hinge 18 has a first seat 18 a attached to the top plate 4 of the cabinet and a seat 26 a of the support fitting 26.
Between the second seat portion 18c attached by welding or the like,
It has a shape connected by a curved portion 18b. Since it is attached inside the top plate 4 of the cabinet, it cannot be seen from the front,
Avoid harming the aesthetics of the cabinet.

The seat 26a of the support fitting 26 and the inner surface of the lower side plate 6b of the door are connected to each other by an equal-load spring 19 in which a flexible metal tape is wound in a spring-like manner to exert elasticity in a winding direction. . The spring may vary in elasticity but may be a coil spring. A bearing 21 that slides on a rail 20 fixed inside the door side plate 6a is attached to the sliding portion 26b of the support fitting 26. A gas damper 22 is provided between the arm 26c and the cabinet to push up the arm 26c by a built-in gas pressure. 23 is a stopper which comes into contact with the upper side of the arm 26c,
When the door is closed, the door 6 comes into contact with the arm 26c to guide the door 6 to a predetermined position. As this stopper,
A block of wear-resistant material may be used, but the use of rollers is suitable. When the door 6 is light and the pressing force of the gas damper is small, there is no problem in use, so this stopper is not necessary. A set of a plate hinge 18, a support fitting 26, an equal load spring 19, a gas damper 22, and the like are provided on both sides of the door 6. If the door 6 is light and stiff enough,
It may be provided only on one side.

With the above structure, the door 6 is attached to the front opening of the cabinet 1. The opening and closing operation is as follows.

When the door 6 closes the opening of the cabinet 1, the support fitting 26 and the like are in the state shown in FIGS. 1 and 2, and the gas damper 22 pushes up the arm 26c of the support fitting to close the door 6. I'm on my own. Since the weight of the door 6 is not extremely large and the elasticity of the equal load spring 19 does not need to be extremely large, the door is kept closed in this state. If it is desired to increase the resilience of the equal load spring to such an extent that the door can be pulled up, it is sufficient to attach a lock fitting provided between the door 6 and the cabinet 1 as provided in a normal door.

When opening the door, as shown in FIG.
First, open this slightly before the opening. When the point of attachment of the gas damper 22 to the cabinet 1 and the point of attachment of the gas damper to the arm 26c are outside the line connecting the rotation center 25 of the curved portion 18b of the plate hinge 18 to the door 6, the gas damper 22 is pushed up by the door 6. Power is added. Although the pulling force of the equal load spring 22 acts on the door 6, the door is held by hand to suppress the rise.

As shown in FIG. 5, the door 6 is further opened until it is parallel to the top plate 4. Since the pushing force of the gas damper 22 is acting on the door 6, the door does not fall suddenly even if the hand is released, and the door 6 is moved along the top plate 4 by the cabinet 4 because of the equal load spring 19. , The door 6 is connected to the sliding portion 2 of the support fitting 26.
6b, while sliding the rail 20, the top plate 4 as shown in FIG.
Is drawn along the upper surface of the. If the retraction elasticity is insufficient, push by hand.

When closing the door, the operation is reversed. By appropriately adjusting the elasticity of the equal load spring 19 and the pushing force of the gas damper 22, the above door opening / closing can be easily performed by only slightly applying a hand force to the door or using little hand force. Can be.

[0022]

【The invention's effect】

(1) Since the elasticity of a spring such as an equal load spring and the elasticity of a gas damper are applied to the door, the door can be opened and closed only by lightly applying a hand.

(2) When the cabinet is opened, the door moves in parallel with the cabinet and is placed on the upper surface of the cabinet, so that it is not necessary to provide a large space above the cabinet. It is sufficient to provide a space above the cabinet that is larger than the thickness of the door.

(3) When opening and closing the door, even if the door attempts to fall due to its weight, the elasticity of a spring such as an equal load spring and the elasticity of a gas damper prevent the door from dropping sharply, or Since it does not fall, there is no danger of injury or damage to property.

(4) Since it is sufficient that the equal load spring and the elasticity of the gas damper are sufficient to assist in manually moving the door, the door can be operated lightly while maintaining the reliability of the manual operation.
