However, the fixing means for fixing the blade body between the support plate and the regulating plate is not limited to this.

For example, at least one of the support plate and the regulating plate has a fitting concave portion or a fitting convex portion, the blade body has a fitting convex portion or a fitting concave portion, and the blade body has a fitting concave portion or a fitting convex portion. The blade body is fixed between the support plate and the regulation plate by fitting the part into the fitting convex part or the fitting recess of at least one of the support plate and the regulation plate by elastic deformation.

Furthermore, the vane of the present invention can be any vane. For example, it may be a stirring blade for stirring the object to be stirred, or a scraper blade for scraping the object to be processed adhering to the inner surface (for example, the bottom or side surface) of the container. Specific scraper blades include bottom scraper blades that scrape off objects to be treated adhering to the bottom of the container, and bottom scraper blades that scrape off objects to be processed adhering to the side surfaces of the container.

Further, the device of the present invention is limited in other configurations as long as it has the above-mentioned blades, a container that accommodates the object to be processed, and a rotation drive unit that supports and rotates the blades within the container. isn't it.

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
FIG. 1 is a perspective view for explaining a stirring blade 100 according to Embodiment 1 of the present invention, and shows the structure of an apparatus 11 using the stirring blade 100.

The device 11 of this first embodiment is a device that stirs an object to be stirred (not shown). The device 11 includes a container (hereinafter also referred to as a stirring container) 10 that accommodates a substance to be stirred, a stirring blade 100 for stirring the substance to be stirred, and a stirring blade 100 that rotates and revolves within the stirring container 10. The apparatus includes a rotation drive section 20 that drives the stirring blade 100, and a support arm 30 that supports the rotation drive section 20 with respect to an apparatus housing (not shown). Note that the material to be stirred may be any material. For example, it may contain a solid substance and a sticky material, or it may be a liquid.

Here, the rotational drive unit 20 rotates the stirring blade 100. Specifically, the rotation drive unit 20 includes a drive source 21, a rotation member 22, and a rotation shaft 23, and the rotation shaft 23 is attached to the rotation member 22 so as to be rotatable about a Yc axis extending in the vertical direction. The rotating member 22 is attached to the rotating shaft of the drive source 21 so as to be rotatable about the Xc axis, which is parallel to the Yc axis and is a certain distance away from the Yc axis. The rotary shaft 23 rotates in the X direction while rotating in the Y direction by this rotation drive unit 20. The stirring blade 100 is attached to the lower end of the rotary shaft 23 by a connecting pin 23a so as to be able to swing around the Zc axis (the axis of the connecting pin 23a), and rotates in the X direction around the Xc axis in the container 10 while moving around the Yc axis. It is designed to rotate in the Y direction around its surroundings.

Next, the structure of the stirring blade 100 used in the device 11 will be explained in detail.

2 is an enlarged view showing the stirring blade 100 shown in FIG. 1, and FIG. 3 is a perspective view showing the stirring blade 100 shown in FIG. It is a diagram. FIG. 4 is a diagram for explaining in detail the blade body mounting member 120 shown in FIG. 3, and FIGS. 3 shows the shape of the blade root body mounting member 120 seen from the A direction, the B direction, the C direction, and the D direction.

The stirring blade 100 includes a pair of blade bodies 110a and 110b, and a blade body attachment member 120 to which the pair of blade bodies 110a and 110b are attached. The blade body mounting member 120 is made of a metal material such as stainless steel, brass, iron, titanium, or the like. The blade bodies 110a and 110b are made of resin such as polytetrafluoroethylene. However, the material of the blade body is not limited to this, and other hard plastics, ceramics, metals, etc. can also be used. In the illustrated embodiment, the blade root body attachment member 120 attaches a pair of blade root bodies 110a and 110b, but the present invention is not limited thereto. One blade body may be attached, or two or more blade bodies may be attached.

The blade body attachment member 120 has a base 120c having an upper part 124 and a lower part 125, and a pair of support parts 120a and 120b fixed to the lower part 125 of the base 120c. The upper portion 124 is a portion connected to the rotating shaft 23 by a connecting pin 23a, and has a pin insertion hole 124a for inserting the connecting pin 23a.

Here, the support portions 120a and 120b have a structure capable of holding the blade base bodies 110a and 110b, respectively. Note that since the support portion 120a and the support portion 120b have the same shape, the support portion 120a on the right side in FIGS. 2 to 4 will be described below.

The support part 120a is provided at a position facing the support plate 122 having a shaft part 122a forming an axis R that rotatably supports the blade body 110a, and a space through which the blade body 110a can be inserted. , has a regulation plate (base plate) 121 that regulates attachment and detachment of the blade body 110a, and a connection plate 123 that connects the support plate 122 and the regulation plate 121. In the support part 120a, in the first position (the position of the blade base body 110a with respect to the support part 120a shown in FIG. 6(a)), the blade base body 110a does not come into contact with the regulation plate 121, and the blade base body 110a can be attached and detached. In the second position (the position of the blade base body 110a relative to the support portion 120a shown in FIGS. 5(a) and 5(b)), the blade base body 110a abuts against the regulation plate 121, and attachment and detachment of the blade base body 110a is restricted. is configured to be The base plate (regulating plate) 121 is fixed to one side of the lower part 125 of the base 120c.

Further, the shaft insertion hole 111 of the blade base body 110a is arranged at a position different from the position of the center of gravity of the blade base body 110a. As a result, when the shaft portion 122a of the blade root body mounting member 120 is inserted into the shaft portion insertion hole 111 of the blade root body 110a, the root portion of the blade root body 110a is attached to the base plate 121 and the support plate 122 due to its own weight. By entering the space between the connecting plate (stopper member) 123 and coming into contact with the connecting plate (stopper member) 123, the blade base body 110a is stopped at a position where the blade base body 110a cannot be attached to or detached from the support portion 120a. That is, when the root portion of the blade body 110a enters the space between the base plate 121 and the support plate 122, movement of the shaft portion 122a of the blade body 110a in the direction of the axis Ra is restricted by the base plate 121. The blade body 110a cannot be attached to or detached from the support portion 120a.

Further, the base plate 121 of the support part 120a is formed with a pin insertion hole (fixing part) 121a into which the blade fixing pin 130a can be inserted, and the blade fixing pin 130a can also be inserted into the support plate 122 of the support part 120a. A pin insertion hole (fixing portion) 122b is formed. Here, a split pin is used as the blade fixing pin 130a. The pin insertion holes 121a and 122b are arranged to match the pin insertion hole 112 of the blade body 110a with the root portion of the blade body 110a in contact with the connection plate 123 of the support portion 120a. Therefore, when the root portion of the blade base body 110a is in contact with the connection plate 123 of the support portion 120a (second position), the pin insertion holes 121a, 122b of the support portion 120a and the pin insertion hole 112 of the blade base body 110a are closed. The split pin 130a can be inserted through the blade, and the blade body 110a is fixed to the blade body attachment member 120 by inserting the split pin 130a. Note that the blade fixing pin 130a is not limited to a split pin, and may be a pin other than a split pin. However, it is desirable to have a structure that prevents the pin from coming out of the insertion hole, for example, a structure in which a ring-shaped rubber material is formed at the tip of the pin.

Similarly, the other blade body 110b is also removable from the support portion 120b of the blade body mounting member 120. Note that when the root portion of the blade body 110b is in contact with the connection plate (stopper member) 123 of the support portion 120b, the blade fixing pin (for example, split pin) 130b is inserted into the pin insertion holes 121a, 122b of the support portion 120b, The split pin 130b can be inserted through the pin insertion hole 112 of the blade body 110b, and the blade body 110b is fixed to the support portion 120b of the blade body attachment member 120 by inserting the split pin 130b.

Next, a procedure for removing and disassembling the stirring blade 100 will be explained.

5 and 6 are diagrams for explaining a method for removing the blade bodies 110a and 110b of the stirring blade 100 shown in FIG. 2 from the blade body mounting member 120, respectively. FIG. 5(a) shows a state in which one blade fixing pin 130a is removed, and FIG. 5(b) shows a state in which one blade body 110b is rotated. FIG. 6A shows a state in which one blade body 110a has been rotated to a detachable position, and a state in which one blade body 110a has been removed from the blade body attachment member 120.

First, the connecting pin 23a fixing the stirring blade 100 shown in FIG. 1 to the rotating shaft 23 is pulled out to remove the stirring blade 100 from the rotating shaft 23. Note that FIGS. 2 and 5(a) are diagrams showing the stirring blade 100 in a removed state, and FIGS. FIG. 2 is a view of the blade 100 viewed from a direction perpendicular to its surface.

Next, as shown in FIG. 5(a), the cotter pin 130a fixing one blade body 110a to the support portion 120a is pulled out. In this state, the blade body 110a is located at a position where it cannot be attached to or removed from the support portion 120a of the blade body attachment member 120. That is, the root portion of the blade body 110a is accommodated in the space between the base plate 121 and the support plate 122 of the support portion 120a, and in this state, the blade body 110a is in contact with the base plate 121, so that the blade The main body 110a cannot be moved in the direction of the axis Ra of the shaft portion 122a (direction perpendicular to the plane of the paper), and the blade body 110a cannot be removed from the support portion 120a of the blade body attachment member 120.

Next, as shown in FIG. 5(b), the blade body 110a is moved from the position where it cannot be attached to and detached from the support part 120a of the blade body attachment member 120 to the position where it can be attached and detached, with the blade body 110a centered around the axis Ra of the shaft part 122a. to rotate the blade body 110a. Then, as shown in FIG. 6(a), the blade root body 110a is rotated to a position where the blade root body 110a can be attached to and detached from the support portion 120a of the blade root body mounting member 120, as shown in FIG. 6(b). Lift the blade body 110a relative to the support portion 120a of the blade root body attachment member 120 so that the shaft portion 122a of the blade root body attachment member 120 comes out of the shaft insertion hole 111 of the blade root body 110a. The blade base body 110a is removed from the blade base body attachment member 120 by moving it in the direction of the axis Ra (direction perpendicular to the paper surface).

Note that the operation of attaching the blade root body 110a to the blade root body attachment member 120 can be performed in a completely reverse procedure to the operation of removing the blade root body 110a from the blade root body attachment member 120.

Further, after pulling out the split pin 130b of the other blade body 110b, the blade body 110b is rotated from the non-removable position to the detachable position to remove the blade body 110b from the support portion 120b of the blade body attachment member 120. I can do it.

In this manner, in the stirring blade 100 of the first embodiment, the blade bodies 110a and 110b can be rotated between the non-removable position and the removable position with respect to the support parts 120a and 120b of the blade body attachment member 120. Since the blade base bodies 110a and 110b are supported, removal of the blade base bodies 110a and 110b can be done by simply removing the blade fixing pin 130a and rotating the blade base bodies 110a and 110b. You can also do the opposite easily.

In addition, the work of attaching the blade bodies 110a, 110b to the support parts 120a, 120b of the blade body attachment member 120 involves inserting the shaft parts of the support parts 120a, 120b of the blade body attachment member 120 into the shaft part insertion holes 111 of the blade body bodies 110a, 110b. This can be completed simply by overlapping and rotating the blade bodies 110a, 110b onto the support parts 120a, 120b of the blade body mounting member 120 so that the blade body 122a is inserted. In addition, when the shaft portions 122a of the support portions 120a, 120b of the blade root body mounting member 120 are inserted into the shaft portion insertion holes 111 of the blade root bodies 110a, 110b, the blade root bodies 110a, 110b rotate by their own weight, and the blade root bodies 110a, 110b rotate by their own weight. When the root portions of blades 110a and 110b come into contact with connecting plates (stopper members) 123 of supports 120a and 120b, blade bodies 110a and 110b are stopped at positions where they cannot be attached or removed. Therefore, it is possible to prevent the blade bodies 110a, 110b from accidentally coming off from the support parts 120a, 120b of the blade body mounting member 120.

Furthermore, by inserting the blade fixing pin 130a into the pin insertion holes 121a, 122b of the support parts 120a, 120b and the pin insertion holes 112 of the blade base bodies 110a, 110b, the blade base bodies 110a, 110b can be more securely attached to the blade base body mounting member. 120.

In addition, the support parts 120a and 120b of the blade body mounting member 120 are composed of a combination of members with a simple structure, such as a regulation plate 121, a support plate 122, and a connection plate 123, so that they are easy to clean, easy to maintain, and hygienic. This makes it possible to increase the safety of the above.
