Description

  The present invention relates to a stirrer unit including a stirrer for stirring liquid stored in a columnar can such as a funnel can.

  Some of the components of the liquid stored in a columnar can such as a funnel can may be precipitated. For example, when this liquid is a paint, the pigment contained in the paint is precipitated. In this case, the concentration of the component differs between the lower layer portion and the upper layer portion of the liquid in the can. Therefore, when the liquid in the can is used, the liquid is agitated to make the concentration of the liquid in the can uniform.

  Patent Document 1 describes an invention of a paint stirrer that is configured by rotatably attaching stirring blades 6 and 7 to the tip of a shaft 2. And in patent document 1, the stirring blades 6 and 7 are made into the non-expanded state with the dead weight with the coating material stirring tool 1 oriented vertically, and in this state, the stirring blades from the coating material discharge port 13 of the upper surface 12a of the Ito can 12 6 and 7 were inserted into the canister 12, the paint stirring tool 1 was tilted in the direction of the arrow C, and the stirring blades 6 and 7 were positioned near the center of the bottom of the canister 12 and attached to the shaft 2. It is described that the electric rotary tool 14 is turned on and operated to stir the paint in the canister 12.

JP 2000-280700 A (paragraphs 0013 to 0015, FIGS. 1 to 4)

  The paint discharge port formed in the columnar can like the Ito can can be used for the convenience of discharging the liquid inside the can by tilting the can, near the corner or edge of the top of the can Is often provided. In this case, in order to efficiently stir the liquid in the funnel 12, the stirring blades 6 and 7 of the paint stirrer described in Patent Document 1 are positioned at the approximate center of the bottom of the funnel 12. The shaft 2 must be tilted as described in particular (FIG. 3). However, in this case, the user keeps holding the electric rotating tool 14 while keeping the shaft 2 inclined, and the operator must operate the switch of the electric rotating tool 14 in this state.

  Here, in order to efficiently stir the liquid in the can, it is also conceivable to open the upper part of the can by cutting the entire upper surface of the can with a scraper. Certainly, in this case, the user can easily insert the shaft of the paint agitator into the inside of the can, and can hold the paint agitator with the shaft oriented vertically. However, in this case, it takes time to open the upper lid with the scraper. Further, there is a risk that the user may come into contact with the edge of the opened can and get injured. Furthermore, metal powder is generated when the scraper is cut, and this metal powder may be mixed into the liquid in the can.

  An object of the present invention is to efficiently and safely stir the liquid in the can body without cutting the upper surface of the can body.

  A stirrer unit of the present invention comprises a shaft, a blade body that is rotatably provided at an end of the shaft and hangs down by its own weight, and a rotation drive unit that rotates the shaft in a direction around its axis; A can body that has a columnar shape and stores liquid therein and forms a liquid discharge port at a non-center position of one end face, with the one end face facing upward and above the center point of the one end face. A can holding unit that tilts and holds the liquid discharge port; and a stirring device holding unit that holds the stirring device with the shaft aligned with a vertical line passing through the liquid discharge port.

  According to the present invention, the blade body can be smoothly guided from the liquid discharge port to the inside of the can body, and further, the interior of the can body such that the blade body does not collide with the inner wall of the can body while the shaft is oriented vertically. Therefore, the liquid in the can can be efficiently and safely agitated without cutting the upper surface of the can.

  One embodiment will be described with reference to FIGS. FIG. 1 is a front view showing how the paint 502 in the can body 501 is stirred using the stirring device unit 101. The stirrer unit 101 includes a stirrer 201, a mounting table 301 as a can holding unit, and a lid 401 as a stirrer holding unit. The stirrer unit 101 efficiently and safely stirs the paint 502 stored in the columnar can 501 without cutting the upper surface (the end surface 503 shown in FIG. 2B, etc.). Used for. In FIG. 1, a part of the side surface of the can body 501 is broken.

  FIG. 2A is a perspective view of an integrated device 51 in which a plurality of stirring device units 101 are integrated. In the present embodiment, the lid 401 of each of the plurality of stirring device units 101 is attached to the long member 52 that extends in the horizontal direction, and both ends of the long member 52 are supported by the support columns 53, so that the integrated device 51 is Composed. In the integrated device 51, the long member 52 is movable in the vertical direction, and the blade body 203 can be positioned in the can body 501 or the blade body 203 can be positioned above the liquid discharge port 504. . Moreover, the support | pillar 53 supports the elongate member 52 by desired height. Here, a hydraulic motor can be employed as an example of a drive source for moving the long member 52 up and down. Hereinafter, one stirring device unit 101 provided in the integrated device 51 will be described in detail. In addition, the elongate member 52 is abbreviate | omitted in each figure after FIG.2 (b).

  FIG. 2B is a perspective view showing how the stirring device unit 101 is attached to the can body 501. A liquid discharge port 504 is formed on one end surface 503 of the can body 501. The liquid discharge port 504 is provided at a non-center position of the end surface 503. An example of such a can body 501 is a canister as shown in FIG. 1 and FIG. The Ito can generally has a rectangular parallelepiped shape, and a liquid discharge port 504 is formed in the vicinity of one corner A1 of the upper surface (end surface 503). When the can body 501 is not opened, a cap 505 is attached to the liquid discharge port 504, and the paint 502 in the can body 501 is sealed. When the user wants to use the paint 502 in the can 501, the user removes the cap 505 to open the liquid discharge port 504, and tilts the can 501 to discharge the paint 502 from the liquid discharge port 504. .

  Please refer to FIG. 1 and FIG. When the paint 502 in the can body 501 is stirred using the stirrer unit 101, the user places the can body 501 on the placing table 301 installed on the floor surface FL. As shown in FIGS. 1 and 2B, the mounting table 301 holds the can body 501 in an inclined manner with respect to the floor surface FL. At this time, the user faces the end surface 503 forming the liquid discharge port 504 upward, and positions the liquid discharge port 504 above the center point CP of the end surface 503.

  FIG. 3A is a plan view of the mounting table 301. FIG. 3B is a plan view showing the mounting table 301 and the can body 501 mounted on the mounting table 301. Reference is made to FIGS. 2B, 3A, and 3B. The mounting table 301 is basically a square flat plate 302. Legs 303 are attached to the lower surface of the flat plate 302. When the mounting table 301 is mounted on the floor surface FL (see FIGS. 1 and 2B), the legs 303 face vertically. At this time, one corner B4 of the flat plate 302 is in contact with the floor surface FL, the corners B2 and B3 adjacent to the corner B4 are aligned at the same height, and the corner is diagonal to the corner B4. B1 is positioned higher than any of the corners B2, B3, and B4. And in the flat plate 302, the dorsal fin portion 304 projects in a direction perpendicular to the flat plate 302 from the corner B4. Further, in the flat plate 302, the pole 305 is oriented in a direction perpendicular to the flat plate 302 from a portion between the corner portion B2 and the corner portion B4 and a portion between the corner portion B3 and the corner portion B4. Is protruding.

  When the can body 501 is placed on the placing table 301, the can body 501 rests against the backrest portion 304 and the pole 305 in an inclined state. At this time, the corner A1 of the end surface 503 of the can body 501 near the liquid discharge port 504 is positioned higher than any of the other corners A2, A3, A4 surrounding the end surface 503. At this time, the corners A2 and A3 adjacent to the corner A1 are both positioned at the same height as the center point CP of the end surface 503. In addition, the corner A4 located opposite to the corner A1 is positioned lower than any of the other corners A1, A2, and A3.

  FIG. 4 is a view taken along arrow A in FIG. 1, showing the stirring device 201 and the lid 401. Please refer to FIG. 2 (b) and FIG. The stirring device 201 is attached to the can body 501 that is held on the mounting table 301 and is inclined. The stirring device 201 includes a shaft 202, a blade body 203, an air motor 204 as a rotation drive unit, an air valve 205, an air hose 206, and an operation lever 207.

  The blade body 203 is attached to one end of the shaft 202 by an attachment shaft 208. The blade body 203 is rotatable with respect to the shaft 202 with the mounting shaft 208 as a rotation center. Then, the blade body 203 hangs vertically from the attachment shaft 208 as shown in FIG.

  The air motor 204 has a rotation drive shaft (not shown). The rotational drive shaft is connected to the other end of the shaft 202. The air motor 204 rotates the rotary drive shaft by the pressure of the air AR sent through the air hose 206. The air hose 206 is detachable from the air motor 204.

  The air valve 205 passes or blocks the air AR fed through the air hose 206 according to the position of the operation lever 207. The operation lever 207 is freely displaceable between an open position 207U for allowing the air valve 205 to pass the air AR and a close position 207L for causing the air valve 205 to block the air AR. The user positions the operation lever 207 at either the open position 207U or the close position 207L, and drives or stops the air motor 204.

  FIG. 5 is a front view of the stirring device 201 and the lid body 401 in a state where the shaft 202 rotates and the blade body 203 spreads. When the user positions the operation lever 207 at the open position 207U, the air valve 205 is opened and the air AR is sent to the air motor 204. The air motor 204 rotates the rotation drive shaft by the pressure of the air AR. As a result, the shaft 202 rotates in the axial direction RA. Here, the blade body 203 rotates in the direction of the direction RB about the mounting shaft 208 by the rotational force of the shaft 202 and spreads in the direction of radiating from the shaft 202. Note that the rotational speed of the shaft 202 can be freely changed by adjusting the pressure of the air AR sent to the air motor 204.

  When the user positions the operation lever 207 at the closing position 207L, the air valve 205 blocks the air AR. Thereby, the air motor 204 stops the rotational drive of the rotational drive shaft. As a result, the shaft 202 stops. The blade body 203 hangs vertically from the mounting shaft 208 due to its own weight.

  FIG. 6 is a perspective view showing a first example of the blade body 203. A first example of the blade body 203 is a long member having an L-shaped cross section. More specifically, the blade body 203 includes a mounting flat plate portion 203a and an extended flat plate portion 203b.

  A groove 202b is formed in the tip portion 202a of the shaft 202. The groove 202 b has a shape that is cut in the length direction of the shaft 202 from the end surface of the shaft 202, and has a concave shape when viewed from the side of the shaft 202. The end portion of the mounting flat plate portion 203 a enters the groove portion 202 b from the end face side of the shaft 202. The mounting shaft 208 passes through the shaft 202 and the mounting flat plate portion 203a. The extended flat plate portion 203b is perpendicular to the mounting flat plate portion 203a from one long side of the mounting flat plate portion 203a and protrudes in the axial direction RA. A part of the tip portion 202a of the shaft 202 (region QA shown in FIG. 6) is formed in a round shape so as not to interfere with the movement of the extended flat plate portion 203b of the blade body 203 rotating in the direction RB. Here, as another embodiment, the blade body 203 rotated in the direction RB with the other long side 203c of the mounting plate portion 203a of the blade body 203 abutting against the bottom surface 202c of the groove 202b is orthogonal to the shaft 202. The orientation may be maintained.

  As shown in FIG. 6, two blade bodies 203 are attached to the shaft 202. These blades 203 are symmetrical with respect to the attachment shaft 208 on each of the flat surfaces formed on the tip portion 202 a of the shaft 202.

  FIG. 7A is a front view showing a second example of the blade body 203. FIG. 7B is a plan view showing a second example of the blade body 203. FIG. 7C is a side view showing a second example of the blade body 203. FIG.7 (d) is an exploded view which shows only the blade body 203 in Fig.7 (a)-FIG.7 (c). Another example of the blade body 203 is a wing-shaped member used as a propeller, which rotates in the direction RB when the shaft 202 rotates in the axial direction RA. In this case, as shown in the region QA in FIG. 6, it is not necessary to form a part of the tip portion 202a of the shaft 202 in a round shape.

  Thus, as the blade body 203, a long member having an L-shaped cross section as shown in FIG. 6 and a blade-shaped member as shown in FIGS. 7A to 7D can be adopted. Further, the blade body 203 may have any shape as long as it has a shape that passes through the liquid discharge port 504 and rotates in the direction RB when the shaft 202 rotates in the direction around the axis RA.

  Reference is again made to FIG. 1 and FIG. The lid body 401 covers the end surface 503 of the can body 501. The lid 401 holds the agitation device 201 at a location that coincides with the liquid discharge port 504 when the end surface 503 is covered. Further, when the cover 401 covers the end surface 503, the shaft 202 coincides with the vertical line VL passing through the liquid discharge port 504. The lid 401 is connected to the air motor 204, and the rotary drive shaft (not shown) and the shaft 202 provided in the air motor 204 are not connected to the lid 401. For this reason, the lid 401 does not rotate when the air motor 204 is driven.

  Meanwhile, as shown in FIG. 1, the mounting table 301 includes a vertical line VL that passes through the liquid discharge port 504 and a virtual line AX that passes through the bottom center point CQ of the can body 501 and extends in the height direction of the can body 501. Thus, the can body 501 is tilted and held. An example thereof is the state shown in FIG. 1, in which the flat plate 302 of the mounting table 301 is inclined by an angle α with respect to the floor surface FL. When the can body 501 is a can, the angle α is about 15 degrees. Then, the lid 401 projects the shaft 202 from the lid 401 by such a length that the attachment shaft 208 is located at the intersection of the vertical line VL and the virtual line AX when attached to such a can 501. Then, the stirring device 201 is held. By positioning the mounting shaft 208 at the intersection of the vertical line VL and the virtual line AX, the blade body 203 does not collide with the inner wall of the can body 501 even if the shaft 202 rotates and the blade body 203 spreads.

  When stirring the paint 502 in the can body 501 using the stirring device unit 101 as described above, the user first places the can body 501 on the mounting table 301. Subsequently, the user removes the cap 505. Subsequently, the user has the stirring device 201 so that the shaft 202 is directed vertically. At this time, the blade body 203 hangs vertically. In this state, the user passes the blade body 203 through the liquid discharge port 504, covers the lid 401 on the end surface 503 of the can body 501, and attaches the stirring device 201 to the can body 501. Thereby, the attachment shaft 208 is positioned at the intersection of the vertical line VL and the virtual line AX.

  Subsequently, the user attaches the air hose 206 to the air motor 204 and positions the operation lever 207 at the open position 207U. Thereby, the air motor 204 is driven, the shaft 202 rotates, and the blade body 203 spreads. Here, the blade body 203 has an L-shaped cross section, and the extended flat plate portion 203b protrudes in the axial direction RA. For this reason, when the shaft 202 rotates, the blades 203 are stirred so as to push down the paint 502, and a flow LQ of the paint 502 as shown in FIG. 1 is generated. The paint 502 is stirred by the blade body 203 and collides with the inner wall of the can body 501 to move in a complicated manner in the can body 501. As a result, the entire paint 502 is uniformly stirred. After stirring the paint 502 in the can body 501 for a predetermined time, the user stops the air motor 204 by positioning the operation lever 207 at the closing position 207L, removes the cover body 401 from the can body 501, and lifts the can body 501. It is carried to a predetermined work place, the can body 501 is inclined, and the paint 502 after stirring is poured out from the liquid discharge port 504.

  As described above, according to the agitator unit 101 of the present embodiment, the blade body 203 can be smoothly guided from the liquid discharge port 504 to the inside of the can body 501, and the blade 202 can be kept in a state where the shaft 202 is directed vertically. The body 203 can be positioned in the vicinity of the center inside the can body 501 so as not to collide with the inner wall of the can body 501. Therefore, it is possible to efficiently and safely stir the paint 502 in the can body 501 without cutting the upper surface of the can body 501. Further, as shown in FIG. 2A, by integrating the plurality of stirring device units 101 to form the integrated device 51, the paints 502 in the plurality of can bodies 501 can be stirred at a time. , Work efficiency can be improved.

  In the above description, it has been described that the attachment shaft 208 is positioned at the intersection of the vertical line VL and the virtual line AX. However, this is the most preferred example, and the mounting shaft 208 is not limited to being positioned at this intersection. As an example, the lid 401 may hold the stirring device 201 so that the mounting shaft 208 is positioned at an internal position of the can body 501 so that the blade body 203 does not collide with the inner wall of the can body 501.

  Moreover, in said description, the case where the can 501 was a one-piece can was described. However, the can body 501 is not limited to a one-piece can, and may have a columnar shape. As an example, a drum can having a cylindrical shape may be used.

  In the above description, the case where the liquid stored in the can 501 is the paint 502 has been described. However, the liquid in the can 501 is not limited to paint. As an example, the liquid may be a seasoning.
