Description

  The present invention relates to a glove port for attaching to a wall part of a glove box and mounting the glove, and further relates to a glove box provided with the glove port.

  In a work performed in an environment with high air cleanliness such as a sterile room or a dust-free room, the worker may work from outside the work room via a glove in order to prevent the work environment from being contaminated by the worker. In addition, work that handles substances harmful to the human body, such as work in the manufacture of pharmaceuticals or research and development, work with radioactive substances, etc., or work in harsh environments such as extremely low temperatures, etc. Work may be performed from outside the room via a glove.

  A working chamber for performing such work is generally called a glove box. In this glove box, for example, a part of a wall portion of a stainless steel box is a transparent glass panel or a transparent acrylic panel. Then, a circular through-hole is formed in the transparent wall portion, and a glove port having a cylindrical portion is attached to the through-hole, and the cylindrical portion of the glove port is projected outside the working chamber. A synthetic resin glove is attached to the cylindrical portion, and the tip of the glove is inserted into the working chamber through the inner surface of the cylindrical portion. An operator works in the glove box through the glove while visually recognizing the inside of the glove box through the transparent wall portion from the outside of the glove box.

  Here, for example, even when two glove ports are attached to the transparent wall portion and an operator works with both hands, it is difficult to operate the entire work room with only two gloves. The ability is greatly limited. Therefore, it is conceivable to secure the workability of the entire work chamber by attaching a large number of globe ports by attaching a large number of globe ports to various parts of the transparent wall portion and other wall portions instead of only two.

  However, if a large number of gloves are arranged on the transparent wall part and the other wall parts, unused gloves occupy the space in the work chamber and workability is reduced. Furthermore, when many through-holes are provided in the transparent wall portion, the distance between the individual through-holes is reduced, and the internal visibility and strength of the transparent wall portion are reduced.

  In order to cope with such a case, in Patent Document 1 below, a main sheet that moves in either the horizontal direction or the vertical direction is attached to the wall of the work chamber, and two gloves are held on the main sheet. A glove box having a pair of main winding mechanisms for moving the glove by winding the main sheet up and down or left and right has been proposed.

  By the way, the mechanism of the glove box described in the above-mentioned patent document 1 is provided in a glove box used for processing work in a severe low dew point environment for workers and employs a winding mechanism having a complicated structure. It does not require strict airtightness. That is, the mechanism proposed in Patent Document 1 has a complicated structure, cannot perform sterilization and dust removal completely and easily, and cannot ensure a strict airtightness. On the other hand, in many glove boxes, a simple structure is required from the viewpoint of sterilization, dust removal or safety in the work room, and in the work in the aseptic room or the work that handles substances harmful to the human body, strict air quality Density is required. Therefore, the mechanism proposed in Patent Document 1 has a problem that it is difficult to widely adopt the glove box used in various environments.

  Accordingly, the present invention addresses the above-mentioned problems, has a simple structure, has a wide work area with a small number of gloves, and can ensure high workability, and can be used in various environments. An object of the present invention is to provide a glove port that can be widely used in a glove box.

In the third embodiment, the globe port 20b includes a cylindrical body 30b, a rotating plate 40b to which the cylindrical body 30b is attached, and a connecting member 50b connected to the outer peripheral edge of the rotating plate 40b. ing.

  In the third embodiment, the configuration and connection state of the connecting member 50b are the same as those in the first embodiment. On the other hand, each structure of the cylinder 30b and the rotating plate 40b is different from that of the first embodiment. That is, the cross-sectional shape of the cylindrical body 30 according to the first embodiment is an ellipse, whereas in the third embodiment, the horizontal cross-sectional shape of the cylindrical body 30b is a conventional fixed round globe port. It has the same circular shape.

  On the other hand, as for the rotating plate 40b, the shape of the outer peripheral edge portion thereof is circular like the rotating plate 40 according to the first embodiment, but in the third embodiment, the rotating plate 40b is opened on the plate surface of the rotating plate 40b. In addition to the shape of the opening being circular, the position of the opening is provided at a position eccentric from the center position of the circular rotating plate.

  In the third embodiment, by forming the opening formed in the rotating plate 40b in a circular shape, the operation of forming the opening in the rotating plate 40b can be performed more easily than an ellipse. In addition, the joining of the inner peripheral edge part and the rotating plate and the joining of the outer peripheral edge part and the work opening of the glass window can be performed in the same manner as in the first embodiment.

  Next, the operation of the globe port 20b configured as described above will be described. Unlike the shape of the insertion part 33 in the said 1st Embodiment, the shape of the insertion part 33b which an operator inserts both arms in a glove is circular. Therefore, in the state where the rotating plate 40b is fixed, the working range of the region where the operator can move the arm along the glass window is limited to that of the conventional fixed round glove port.

  However, as described above, the cylindrical body 30b is provided at a position eccentric from the center position of the rotating plate 40b. Thus, the operator can rotate the insertion portion 33b of the cylindrical body 30b fixed to the rotating plate 40b in the circumferential direction with respect to the connecting member 50b by moving the arm. For example, an area where the operator can move his arm along the glass window by rotating the rotating plate 40b by 90 degrees in the vertical direction is expanded as indicated by a hatched portion C shown in FIG. .

Therefore, also in the third embodiment, the range in which the operator can move the arm (shaded portion C shown in FIG. 10) is the range in the conventional fixed round glove port (shaded portion B in FIG. 9). ) More clearly spread, which increases the work area in the work chamber and improves the workability in the glove box.

  In the fourth embodiment, the configuration and coupling state of the connecting member 50c are the same as those in the first embodiment. On the other hand, each structure of the two cylinders 30c and the rotating plate 40c is different from that of the first embodiment. That is, the cylindrical body 30 according to the first embodiment has an elliptical cross-sectional shape, whereas in the fourth embodiment, the two cylindrical bodies 30c have the same cross-sectional shape as the third embodiment. It has the same circular shape as the conventional fixed round glove port.

  On the other hand, the outer peripheral edge of the rotating plate 40c is circular like the rotating plate 40 according to the first embodiment, but in the fourth embodiment, the surface of the rotating plate 40c is 2 on the plate surface. Two openings are opened, and the shapes of these two openings are both circular. Further, the positions of these two openings are eccentric from the center position of the circular rotating plate 40c and are provided at positions symmetrical with respect to the center.

  In the fourth embodiment, by forming the opening formed in the rotating plate 40b in a circular shape, the operation of forming the opening in the rotating plate 40b can be performed more easily than an ellipse. In addition, the joining of the inner peripheral edge part and the rotating plate and the joining of the outer peripheral edge part and the work opening of the glass window can be performed in the same manner as in the first embodiment.

  Next, the operation of the globe port 20c configured as described above will be described. The two insertion portions 33c through which the operator inserts both arms into the glove are both fixed to the same rotating plate 40c, and the shapes of the two insertion portions 33c are the insertion portions in the first embodiment. Unlike the shape of 33, it is circular. Therefore, in the state where the rotating plate 40b is fixed, the area where the operator can move the arm along the glass window is the same as the conventional fixed circular glove port, and the working range is limited.

  However, as described above, the two cylindrical bodies 30c are fixed to the same rotating plate 40c, and are provided at positions that are eccentric from the central position of the rotating plate 40c and are symmetric with respect to the center. Thus, the operator can rotate the insertion portions 33c of the two cylindrical bodies 30c fixed to the rotating plate 40c as a single unit in the circumferential direction with respect to the connecting member 50b by moving both arms. . For example, when the worker rotates the rotating plate 40c in the vertical direction by 90 degrees, the region in which the worker can move the arm along the glass window is enlarged as indicated by the hatched portion D shown in FIG. .

  Accordingly, also in the fourth embodiment, the range in which the operator can move the arm (shaded portion D shown in FIG. 11) is the range in the conventional fixed round glove port (shaded portion B in FIG. 9). ) More clearly spread, which increases the work area in the work chamber and improves the workability in the glove box.

  The globe port of each embodiment configured as described above has a simple structure. This makes it easy to manufacture the glove port and allows easy attachment to the glove box. Moreover, operations such as cleaning and sterilization inside the glove box are facilitated, and high workability can be ensured.

  Moreover, since the cylinder body into which the operator inserts the arm can move along the wall surface of the glove box, the work area in the glove box is expanded. Therefore, it is not necessary to attach many gloves to the wall surface of the glove box, and the work area can be wide and high workability can be ensured even with a small number of gloves.
