Description

DOOR OPEN AND SHUTTING ASSEMBLY FOR STERILIZING MACHINE}

The present invention relates to a door opening and closing structure of the sterilizer, and more particularly, in the sterilizer is sterilized by the high-pressure steam door opening and closing structure to facilitate the locking and unlocking operation of the operator's door for internal sealing It is about.

In general, various medicines and drug containers containing their medicines should be treated aseptically, but there are several means for sterilization thereof, but in the case of medicines, it is not preferable to sterilize them with a separate sterilizing medicine. When materials and chemical containers are brought into the manufacturing process, it is common to sterilize them with high-pressure steam.

As described above, a sterilizer for sterilizing a medicine or a medicine container containing the medicine as high pressure steam has doors formed at both sides of the high pressure steam chamber, and one door is disposed toward the outside, and the other door is sterilized by being disposed at the clean room side. During operation, the sterilized drug or drug container is brought into the high-pressure steam chamber through the outer side door and sterilized in the steam chamber and then taken out to the sterile side and brought into the manufacturing process.

The high pressure steam sterilizer is supplied with high pressure steam to the high pressure steam chamber, so that the sealed state must be firmly maintained and the locked state can be surely sterilized.

Looking at an example of the opening and closing method of the door of the conventional sterilizer through Figure 1, to enable the opening and closing of the hinge portion 101 is provided on one side rotationally, the latch 102 on the opposite side of the hinge portion of the door 100 Provided to maintain the locked state, but for a more robust locking state by placing the rotating plate 103 in the center of the door and a plurality of locking rods 104 radially disposed on the rotating plate 103 of the locking rod 104 The front end portion is inserted into a fixing ring (not shown) formed in the outer part sterilizer body of the door 100, so that a rigid lock is made.

However, in the case of the door opening and closing means as described above, the opening and closing operation of the door is made by hand, and the auxiliary locking device must be operated, which is cumbersome, and if the operator does not accidentally lock the auxiliary locking device, it is sealed. There is a problem that the sterilization operation is not made properly because the state is not maintained firmly.

The present invention has been proposed to solve the above problems in the prior art, to provide a door opening and closing structure to be made easier and more robust in performing the locking and unlocking operation of the opening and closing door by the operator. The purpose is to.

1 is a perspective view of a sterilizer constituting a door opening and closing structure of the prior art.

Figure 2 is a perspective view for showing the door opening and closing structure of the sterilizer according to an embodiment of the present invention.

The above object is a high steam sterilizer for sterilizing with high-pressure steam is installed on the door arm hinged to one side, the door arm is coupled to the opening and closing door door of the sterilizer which is installed in a conventional sliding form The door arm has a cylinder member mounted at a hinge coupling portion to allow up and down flow; The opening and closing door is provided with a first uneven portion continuous along the outer circumferential surface in a predetermined section; The sterilizer main body has a second uneven portion having the same shape so as to correspond to the uneven portion of the opening and closing door; The inside of the second concave-convex portion is provided with a sliding groove to enable the vertical sliding operation during the opening and closing operation of the opening and closing door; it can be achieved through the door opening and closing structure of the sterilizer.

Hereinafter, a specific embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3.

First, referring to FIG. 2, a door arm 3 is installed at one side of the sterilizer body 1 to open and close the hinge shaft 2, and the door arm 3 is opened and closed. Is fixedly installed to form a structure capable of sealing the inside of the sterilizer by the locking operation of the opening and closing door 4 which is hinged.

The opening and closing door 4 is formed to form a concave-convex shape in which the first concave-convex portion 5 is continuous along the outer edge, and the first concave-convex portion 5 is formed on the inlet-side frame 6 of the sterilizer main body 1. After forming the corresponding second uneven portion 7 and the sliding groove 8, the first uneven portion 5 is the second uneven portion 7 by the raising or lowering operation of the opening / closing door 4 after the interdigital insertion. It was configured to be locked in contact with the inner side of the.

In particular, the first concave-convex portion 5 and the second concave-convex portion 7 form a concave-convex shape in which protrusions and inrushes are continuously formed in a “c” shape, respectively, thereby forming a structure in which the protruding portions completely contact during locking operation. The stable locking state can be maintained.

On the other hand, the hinge shaft (2) of the door arm (3) is installed in a state capable of linear flow in the vertical direction, the lower end portion is equipped with an operating cylinder (9) for providing a vertical flow force.

In the figure, reference numeral 10 denotes a support housing for supporting up and down flow of the hinge shaft 2.

Looking at the operation state and the resulting effects of the present embodiment constituting such a configuration as follows.

Since the opening and closing door 4 fixedly coupled to the door arm 3 is rotatable around the hinge shaft 2, when the closing door 4 is closed to seal the inside of the sterilizer, the opening and closing door 4 is shown in FIG. 3A. As described above, the first uneven portion 5 of the opening / closing door 4 passes through the second uneven portion 7 formed in the sterilizer main body 1 and is located in the sliding groove 8 formed therein. Done.

When the operator operates the operation cylinder 9 by operating the lock switch of the control panel (not shown) in this state, the hinge shaft 2 is linearly moved downward, and accordingly, the door arm 3 of the hinge shaft The open and close doors 4 coupled to each other flow down along the sliding grooves 8.

In addition, the opening and closing door 4 which is slid and flows as described above is able to maintain a stable locking state by forming the first concave-convex portion 5 in close contact with the second concave-convex portion 7 as shown in FIG. 3B. .

On the other hand, when the sterilization operation by the high-pressure steam is performed in the locked state to release the lock state of the opening and closing door (4) is performed in the reverse order to the above-described locking operation.

That is, when the operator operates the operation cylinder 9 by operating the release switch of the control panel panel, the hinge shaft 2 performs an upward linear movement, and thus the opening / closing door 4 moves the sliding groove 8 together. It will flow upward.

Accordingly, the first uneven portion 5 of the opening / closing door 4 may be in the state of FIG. 3A through which the first uneven portion 5 may pass through the second uneven portion 7 of the sterilized base body 1. 3) Pull and open the door (4) is naturally rotated along the hinge shaft (2) to achieve an open state.

On the other hand, while a specific embodiment of the present invention has been described above, it is obvious that the opening and closing door structure of the present invention may be variously modified and implemented by those skilled in the art.

However, such modified applications should not be individually understood from the technical spirit or prospect of the present invention, and other modified embodiments should fall within the appended utility model claims of the present invention.

As described above, the sterilizer door structure of the present invention, in the sterilizer in which the sterilization operation is performed by high pressure steam, can be made to lock and unlock the doors stably and easily by the action of the cylinder, so that the reliability of the sterilizer device can be achieved. It is a useful design that can be improved.
