Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view (schematic view) showing an example of the syringe defoaming device 10 according to the embodiment of the present invention, in which a part of the upper portion is cut out so that the inside can be visually recognized. FIG. 2 is a cross-sectional view (schematic view) of the syringe defoaming device 10 from the front direction. FIG. 3 is a plan view (schematic view) of the syringe defoaming device 10, showing a state in which the member on the upper surface is removed, and the internal configuration of the holder 50 and the syringe 36 are shown by broken lines. FIG. 4 is a cross-sectional view (schematic view) showing an example of a syringe 36 used in the syringe defoaming device 10 of FIG. 1 as a container filled with a paste-like material. In all the drawings, members having the same function are designated by the same reference numerals, and the repeated description thereof may be omitted.

First, the syringe defoaming device 10 (hereinafter, may be simply referred to as “device 10”) according to the embodiment of the present invention shown in FIG. 1 is formed in a square shape, and an operation unit 12 such as a power switch is formed on a side surface thereof. It is equipped with. On the upper surface, a circular top plate 14 is provided from the central portion to the vicinity of the edge portion, and a vacuum chamber 26, which is a cylindrical accommodation space, is provided directly below. The top plate 14 has an opening / closing cover 16 provided so as to be openable / closable by a hinge 18.

Next, the internal configuration of the device 10 will be described. Inside the device 10 shown in FIG. 2, a driving means for rotationally driving the revolving member 24 is provided. The drive means includes a drive shaft 32 and a drive motor 34.

The second opening 42 is closed by a closing means 42a such as a cap or a luer lock, while the first opening 38 is normally opened to expel defoamed air bubbles, but has holes. A cap or the like may be attached. Although the first opening 38 has a brim 38a, it can be used in the syringe device 10 regardless of the presence or absence of the brim 38a.

Subsequently, the configuration of the holder 50 in which the syringe 36 is housed and held will be described. 5 and 6 are schematic views showing an example of the holder 50 (FIG. 5 is a perspective view, and FIG. 6 is a plan view). Further, FIGS. 7 and 8 show a schematic view (plan view) of an example in which the syringe 36 is housed in the holder 50, of which FIG. 6 shows the syringe 36 having a relatively large size (total length and outer diameter). FIG. 7 shows an example in which a syringe 36 having a relatively small size (total length and outer diameter) was housed.

The holder 50 shown in FIGS. 5 and 6 has a rectangular parallelepiped outer shape and includes a cylindrical accommodating portion 52 penetrating both sides in the longitudinal direction. The accommodating portion 52 has a first accommodating portion 56 having a first end portion 54 having a relatively small inner diameter at one end and formed to have a relatively small inner diameter, and a second end having a relatively large inner diameter at the other end. It has a second accommodating portion 60, which has a portion 58 and is formed to have a relatively large inner diameter. The first accommodating portion 56 and the second accommodating portion 60 are provided so as to communicate with each other inside the holder 50, and the innermost portion 60a of the second accommodating portion 60 is penetrated by the first accommodating portion 56. The holder 50 is constructed by using urethane resin as an example, but the constituent material is not limited to this.

As shown in FIG. 7, the syringe 36 is inserted from the second end 58 into the accommodating portion 52 of the holder 50 with the second opening 42 of the tip 44a first. When the shoulder portion 44b continuous with the tip portion 44a of the syringe 36 reaches the innermost portion 60a of the second accommodating portion 60, the small diameter portion 44 is accommodated in the first accommodating portion 56 and the large diameter portion 40 is accommodated in the second accommodating portion 40. It is housed in part 60. More specifically, the small diameter portion 44 has a large diameter portion 44 while the tip portion 44a is positioned inside without protruding from the first end portion 54 and is completely accommodated in the accommodating portion 52 (first accommodating portion 56). The accommodating portion 52 (second accommodating portion 60) has the rear end portion 40a located outside the second end portion 58, that is, with the rear end portion 40a protruding from the second end portion 58 side. Is housed in. As a result, even if the total length of the syringe 36 is different, it can be held by one type of holder 50, the holder 50 is accommodated in the fitting groove 46 as described later, and the protruding rear end portion 40a is accommodated in the fitting groove 46. It can be accommodated in the auxiliary groove 48 provided in communication. Reference numeral 47 is a hole for hooking a finger when the holder 50 is taken in and out.

Further, the syringe 36 can be removed from the holder 50 by pulling out the protruding rear end portion 40a. The second accommodating portion 60 is formed to have substantially the same widthwise dimension as the syringe 36 as long as the syringe 36 can be taken in and out (movable in the longitudinal direction) in a plan view, and the first seal 70 described later is formed. Is provided.

Further, the syringe 36 in the accommodating portion 52 is supported by the shoulder portion 44b being brought into contact with the innermost portion 60a of the second accommodating portion 60. FIG. 7 shows a configuration in which the stopper 66 is attached to the innermost portion 60a of the second accommodating portion 60 and the shoulder portion 44b is brought into contact with the stopper 66, but the shoulder portion 44b is attached to the innermost portion 60a. It may be configured to be in direct contact with the. Further, a first seal 70 is provided on the inner peripheral portion of the second accommodating portion 60, and is pressed against the outer peripheral portion of the syringe 36 (large diameter portion 40). Thereby, the outer peripheral portion of the large diameter portion 40 can be supported by the second accommodating portion 60, and the syringe 36 is displaced into the accommodating portion 52, that is, the holder 50 by the supporting means and the supporting means in the shoulder portion 44b. It can be fixed so as to prevent wobbling and the like. The stopper 66 is configured as a tubular member using urethane resin as an example, but the constituent material is not limited to this. A rubber O-ring is used as an example of the first seal 70, but the shape, size, number, and the like are not limited. Further, the position where the first seal 70 is provided is not limited.

Here, there are a plurality of types of syringes 36 having different total lengths or outer diameters. Therefore, a plurality of types of stoppers 66 may be prepared according to the total length of the syringe 36 and the shapes of the tip portion 44a and the shoulder portion 44b, and may be selectively used according to the type of the syringe 36. For example, as shown in FIG. 8, when the total length of the syringe 36 is relatively small, a stopper 66 having a longer overall length than that of FIG. 7 may be provided at the innermost portion 60a of the second accommodating portion 60. As a result, the small diameter portion 44 is accommodated in the cylinder of the stopper 66 instead of the first accommodating portion 56, and the shoulder portion 44b is supported by being brought into contact with the stopper 66 instead of the innermost portion 60a of the second accommodating portion 60. can do. Depending on the type of the syringe 36, the stopper 66 may not be used, or one or a plurality of stoppers 66 may be used.

On the other hand, as shown in FIG. 8, when the outer diameter of the syringe 36 is relatively small, the adapter 68, which is a tubular member, is provided inside the second accommodating portion 60. As a result, the large-diameter portion 40 can be accommodated in the cylinder of the adapter 68, and the gap between the inner peripheral portion of the second accommodating portion 60 and the outer peripheral portion of the large-diameter portion 40 can be filled. A plurality of types of the adapter 68 are prepared according to the outer diameter of the outer peripheral portion of the syringe 36, and may be selectively used according to the type of the syringe 36. Depending on the type of the syringe 36, the adapter 68 may not be used, or one or more adapters 68 may be used. Further, the adapter 68 is configured by using urethane resin as an example, but the constituent material is not limited to this.

A second seal 72 is provided on the inner peripheral portion of the adapter 68, and is in pressure contact with the outer peripheral portion of the syringe 36 (large diameter portion 40). At this time, the first seal 70 provided on the inner peripheral portion of the second accommodating portion 60 is in pressure contact with the outer peripheral portion of the adapter 68. According to this configuration, the large diameter portion 40 of the syringe 36 can be pressed against the second seal 72 to be supported by the adapter 68, and the adapter 68 supporting the syringe 36 is pressed against the first seal 70 to be brought into contact with the second seal 70. It can be supported by the accommodating portion 60. That is, by fixing the syringe 36 to the adapter 68 fixed to the storage portion 52 and integrated with the storage portion 52, the syringe 36 can be fixed in the storage portion 52, that is, the holder 50 as a result. A rubber O-ring is used as an example of the second seal 72, but the shape, size, number, and the like are not limited. Further, the position where the second seal 72 is provided is not limited.

It is also possible to have a configuration in which either one or both of the first seal 70 and the second seal 72 is not provided. However, even in those cases, the gap between the members of the accommodating portion 52, the adapter 68, and the syringe 36 is set to be small as long as each member can be taken in and out (movable in the longitudinal direction), and the holder It is preferable that the operation (shift, wobbling, etc.) of the syringe 36 in 50 is prevented.

Subsequently, the configuration of the fitting groove 46 into which the holder 50 is fitted (accommodated) and the auxiliary groove 48 will be described. The fitting groove 46 provided in the revolving member 24 shown in FIG. 3 is a concave groove formed in a rectangular shape substantially the same as the holder 50, and is radially inward with respect to the fitting groove 46. Auxiliary grooves 48 are provided in communication with each other. The auxiliary groove 48 is formed so that the circumferential dimension (shortward dimension) is larger than the rear end portion 40a of the syringe 36 (in the case of the syringe 36 having the brim portion 38a, the length including the brim portion 38a) in the plan view. The radial dimension is formed in a concave groove formed larger than the rear end portion 40a protruding from the holder 50. As a result, even when the amount of protrusion from the holder 50 is changed by the syringes 36 having different overall lengths, the first end portion 54 is directed outward in the radial direction and the second end portion 58 is directed inward in the radial direction. By fitting the holder 50 into the fitting groove 46, the rear end portion 40a of the syringe protruding from the second end portion 58 side of the holder 50 can be accommodated in the auxiliary groove 48 communicating with the fitting groove 46. can.

Further, according to the above configuration, the second opening 42 (small diameter portion 44) of the syringe 36 is directed outward in the radial direction, and the first opening 38 (large diameter portion 40) is directed inward in the radial direction. It can be arranged at 24. As a result, when the syringe 36 filled with the paste-like material is revolved, the material is moved to the small diameter portion 44 side on the radial outer side and the bubbles are moved to the large diameter portion 40 side on the radial inner side by centrifugal force. The bubbles can be defoamed by separating them from each other and discharging air bubbles from the first opening 38.

Further, the auxiliary groove 48 is configured to have a circumferential dimension smaller than that of the fitting groove 46 in a plan view. Therefore, in the communication portion between the fitting groove 46 and the auxiliary groove 48, the structure may have a support wall 74 in which the radial dimension of the fitting groove 46 matches the longitudinal dimension of the holder 50. Therefore, the end surface of the second end portion 58 of the holder 50 near the side can be supported. That is, on the second end 58 side of the holder 50, the rear end 40a of the syringe 36 protruding from the center can be accommodated in the auxiliary groove 48, and the end surface closer to the side can be supported by the support wall 74. A possible configuration is realized. As a result, the holder 50 is supported by the support wall 74 on the second end 58 side and by the wall surface of the fitting groove 46 on the other side surfaces, so that the rear end 40a of the syringe 36 is projected. Even so, the movement in the radial direction can be restricted and the fitting groove 46 can be fitted, and the fitting groove 46, that is, the revolving member 24 can be fixed.

The fitting groove 46 is formed so that the four corners of the concave groove formed in a rectangular shape are hollowed out so as to expand outward (FIGS. 3, 7, and 8). As a result, even when the fitting groove 46 is formed in a rectangular shape substantially the same as the holder 50, the holder 50 can be easily operated in the height direction of the fitting groove 46, so that the holder 50 can be smoothly taken in and out. It can be performed.

In addition, as a modified example, the holder 50 in a state where two fitting grooves 46 are overlapped in the height direction may be formed to have a depth dimension that allows fitting (not shown). As a result, by fitting the two holders 50 into the fitting groove 46 in a stacked state, it becomes possible to defoam a larger number of syringes in one operation. Further, as another modification, the holder 50 may be configured as a two-stage holder that is integrally formed and has two accommodating portions 52 in the height direction (not shown). As a result, the two-stage holder is fitted into the fitting groove 46 having a depth dimension that allows the holder 50 in a state of being stacked in the height direction to be fitted. It is possible to defoam a larger number of syringes in one operation. The number and arrangement of the fitting grooves 46 in the present embodiment are examples, and the second opening 42 (small diameter portion 44) of the syringe 36 is directed outward in the radial direction, and the first opening 38 (large diameter portion 40) is directed. ) Is arranged in the revolving member 24 inward in the radial direction, and can be variously deformed as in the above-mentioned modification.

As described above, according to the syringe defoaming device according to the present invention, the shoulder portion is brought into contact with the innermost portion of the second accommodating portion for a plurality of types of syringes having different overall lengths, and the small diameter portion is formed. The large-diameter portion can be accommodated in the first accommodating portion, and the large-diameter portion can be accommodated in the second accommodating portion in a state of protruding from the second end portion and held by the holder. The amount of protrusion from the holder varies depending on the syringes having different overall lengths, but by fitting the holder into the fitting groove, the rear end of the syringe protruding from the holder can be accommodated in the auxiliary groove communicating with the fitting groove. ..

Further, when the total length of the syringe is relatively small, the rear end portion of the syringe can be projected from the holder by providing a stopper in the accommodating portion. Further, when the outer diameter of the syringe is relatively small, the gap between the accommodating portion and the syringe can be filled by providing an adapter in the accommodating portion. By selectively providing the stopper and the adapter according to the total length or the outer diameter of the syringe, the syringe can be held in the holder even if the total length of the syringe differs significantly or the outer diameter differs. ..

The holder can support the second end side even when the rear end of the syringe is projected by the support wall formed in the fitting groove, so that the holder can move in the radial direction. It can be regulated and fitted into the fitting groove and fixed to the fitting groove, that is, the revolving member.

The present invention is not limited to the embodiments described above, and can be variously modified without departing from the present invention.
