Therefore, workers do not need to scrape off any remaining mixed mixture inside the bowl, avoiding the risk of safety accidents.

Description

Technical Field

[0001] The present invention relates to a stirring device and an automatic food stirring system including the stirring device. Background Technology

[0002] Used for kneading or mixing large quantities of pastry or bread ingredients at once. Confectionery and baking ingredients are typically separated from egg yolks. Place them in a mixing bowl and knead or beat using a mixer.

[0003] In the process of making cookies or bread, the process of mixing wheat flour and other grain flours with various other ingredients is very important. Even the time spent mixing, or kneading, plays a crucial role.

[0004] In other words, since kneading speed, pressure, and the time it takes for flour to form gluten are very important factors, a specialized pastry and baking mixer should be used when kneading large quantities of pastry and baking ingredients.

[0005] These candy and baking mixers place the ingredients to be kneaded in a mixing bowl with a hemispherical bottom, which is then fixed to a table at the bottom. The table then rises, forming a mixing tool on top. It enters the mixing bowl and begins mixing.

[0006] However, traditional confectionery and baking mixers have a problem: workers must manually scrape out the mixed ingredients after mixing.

[0007] In particular, during this process, there is a problem of unexpected operation of the mixer, which often leads to fatal accidents for workers.

[0050] The mixing apparatus according to this embodiment includes a main body (100), a bowl (200) mounted on the main body (100) and configured to mix materials to form a mixture, and a mixing device (200) that mixes materials while rotating inside the bowl (200). It also includes an impeller assembly (300), a scraper assembly (400) that rotates along the inner surface of the drum (200) and scrapes materials, and a means for simultaneously driving the impeller assembly (300) and the scraper assembly (400). It includes a drive module (500) and a valve assembly (600) located at the bottom of the bowl (200) and configured to selectively open the bowl (200) to discharge the mixed mixture to the bottom of the bowl (200).

[0051] The aforementioned mixing materials can be categorized into sugar-based mixing materials or soft mixing materials based on their moisture content. The mixing device in this embodiment can form dough with a moisture content of 35% to 75% and features automatic discharge via the valve assembly (600). More than

[0052] The aforementioned stirring device may be part of an automated food stirring system. The aforementioned automated food stirring system includes a first supply line (not shown) for supplying a first material to a bowl (200), a second supply line (not shown) for supplying a second material to a bowl (200), and a water supply line (not shown) for supplying water to a bowl (200).

[0053] The bottom of the valve assembly (600) may also be fitted with a container (not shown) for storing and moving the discharged agitated material.

[0054] The aforementioned automated food mixing system can automatically supply the first material, the second material, and water into the bowl (200), and after mixing is completed, completely discharge the mixed material into the container through the valve assembly.

[0055] The automated food mixing system of this embodiment can automatically repeat the above process by resupplying the first material, the second material, and water after the mixed material is discharged, and it has the characteristic of minimizing human intervention in the process.

[0056] The drive motor (510) of the body (100) is configured to operate the impeller assembly (300) and the scraper assembly (400) simultaneously. The drive motor (510) is located on the upper part of the bowl-shaped body (200).

[0057] The container has a base portion (110), a vertical body portion (120) disposed perpendicular to the base portion (110), and a top body portion (130) disposed above the vertical body portion (120).

[0058] The aforementioned bowl (200) is placed on the underside of the top main body part (130).

[0059] The top main body (130) and the bottom main body (110) are arranged opposite each other in the vertical direction.

[0060] The impeller assembly (300) and scraper assembly (400) are driven in the top main body section (130). A drive module (500) is placed therein.

[0061] The aforementioned drive module (500) includes a drive motor (510) and a gearbox (520), which is connected to the motor shaft (515) of the drive motor (510) and operates and rotates by the driving force of the drive motor (510).

[0062] The motor shaft (515) is set vertically along the vertical direction, and the rotation center of the motor shaft (515) is called the rotating shaft (C).

[0063] The impeller assembly (300) and scraper assembly (400) are assembled onto the aforementioned gearbox (520).

[0064] The scraper assembly (400) is mounted on the gearbox (520) and rotates in the direction of rotation of the gearbox (520). The scraper assembly (400) rotates about the rotation axis (C).

[0065] The impeller assembly (300) rotates along the rotation direction of the gearbox (520) and is driven by the gearbox (520). The impeller assembly (300) rotates about the rotation axis (C).

[0066] Various structures can be used to simultaneously achieve the rotation and revolution of the impeller assembly (300). For example, a ring gear-planetary gear-sun gear structure can be used. The motor shaft (515) can be connected to the sun gear, and the impeller shaft, described later, can be assembled onto this gear. The ring gear-planetary gear-sun gear structure is a common technique for those skilled in the art, and therefore will not be described in detail.

[0067] The impeller assembly (300) and scraper assembly (400) are arranged horizontally relative to the axis of rotation (C). The impeller assembly (300) and scraper assembly (400) rotate simultaneously when assembled into the gearbox (520), and the impeller assembly (300) also rotates during the rotation, thereby agitating the material.

[0068] The scraper assembly (400) is located on one side of the aforementioned rotation axis (C), and the impeller assembly (300) is located on the other side.

[0069] A valve assembly (600) is mounted on the bottom and top of the aforementioned bowl (200). It includes an open hemispherical bowl portion (210) and a cylindrical portion (220) extending upward from the top of the bowl portion (210).

[0070] The bowl-shaped body (200) has a bowl-shaped space (201) inside.

[0071] The bottom of the aforementioned bowl-shaped object (210) has an outlet (215) through which the agitated material is discharged. The aforementioned valve assembly (600) selectively opens and closes the discharge port (215). The lower side of the aforementioned bowl-shaped space (201) is open downward through the discharge port (215).

[0072] The aforementioned bowl-shaped portion (210) is a hemispherical shape that is concave towards the bottom, and an outlet (215) is formed at the far end. The aforementioned outlet (215) is provided on the rotating shaft (C).

[0073] The aforementioned cylindrical portion (220) is a hollow cylinder, and its lower end is connected to the upper end of the bowl-shaped portion (210). The cylindrical portion (220) is formed by extending upward from the upper part of the bowl-shaped portion (210).

[0074] The inner diameter of the cylindrical portion (220) is the same as the inner diameter of the upper part of the bowl-shaped portion (210).

[0075] The increased length of the cylindrical portion (220) allows for easy increase in the internal volume of the bowl (200). Since the stirring device of this embodiment can scrape off the stirring material adhering to the inner wall of the bowl (200) using the scraper assembly (400) without requiring an operator to enter the bowl (200), the internal volume of the bowl (200) can be made larger.

[0076] The aforementioned stirring device also includes a cover (140) fixed to the top main body (130) and extending downward, the cover (140) being configured to cover the open upper surface of the cylindrical part (220).

[0077] The aforementioned cover (140) is formed to surround the gearbox (520). The cover (140) is funnel-shaped, and its cross-sectional area increases towards the bottom.

[0078] The impeller assembly (300) is mounted on top of a gearbox (520), rotates about a motor shaft by the rotation of the gearbox (520), and is rotated by a driving force transmitted from the gearbox (520). The impeller shaft (310) and the rotating shaft connected to the lower end of the impeller shaft (310) include the impeller component (320).

[0079] The impeller shaft (310) includes an upper impeller shaft (311) assembled on the gearbox (520) and a lower impeller shaft (312) connecting the upper impeller shaft (311) and the impeller component (320).

[0080] The lower impeller shaft (312) can move up and down relative to the upper impeller shaft (311) and can be fixed to the upper impeller shaft (311).

[0081] The height of the impeller component (320) can be adjusted by moving the lower impeller shaft (312) up and down.

[0082] The impeller component (320) includes an impeller hub (325) connected to the lower end of the impeller shaft (310) and blades (321) extending downward from the impeller hub (325).

[0083] Viewed from above, the impeller hub (325) is circular, and the lower end of the lower impeller shaft (312) is joined to the center of the plane of the impeller hub (325).

[0084] The impeller shaft (310) forms the rotation center (D) of the impeller assembly (300).

[0085] The blades (321) mentioned above are arranged in multiple pieces. The multiple blades (321) are arranged radially with the rotation center (D) of the impeller shaft (310) as the center.

[0086] Multiple blades (321) are arranged at equal angles with the rotation center (D) as the reference.

[0087] The lower ends of each blade (321) converge to form the lower end of the impeller (324).

[0088] The lower part of the impeller (324) is located below the center of rotation (D).

[0089] The lower part of the impeller (324) is located outside the discharge port (215) and rotates along the edge of the discharge port (215).

[0090] In other words, when the impeller assembly (300) rotates, the lower part of the impeller (324) will not protrude into the outlet (215), thereby preventing contact with the valve assembly (600).

[0091] The impeller assembly (300) rotates clockwise or counterclockwise around the rotation center (D) and revolves along the edge of the outlet (215).

[0092] Each of the aforementioned blades (321) includes a blade bend (322) that is in close contact with the inner surface of the bowl (210). The curvature of the aforementioned blade bend (322) corresponds to the curvature of the inner surface of the aforementioned bowl (210).

[0093] Therefore, when the impeller assembly (300) rotates, it can stir the material while scraping off the stirring material attached to the inner surface of the bowl (210).

[0094] The scraper assembly (400) includes: a scraper shaft (410), the upper part of which is mounted on a gearbox (520) and rotates around a motor shaft by rotating the gearbox (520); a position adjustment assembly (460), located at the lower part of the scraper shaft (410); and a scraper piece (450), which is mounted on the position adjustment assembly (460) and rotates along the inner surface of the drum (200).

[0095] The aforementioned scraper shaft (410) includes an upper scraper shaft (411) mounted on a gearbox (520) and a lower scraper shaft (412) connecting the upper scraper shaft (411) and the scraper component (450).

[0096] The lower scraper shaft (412) can move up and down relative to the upper scraper shaft (411) and can be fixed to the upper scraper shaft (411).

[0097] The height of the scraper component (450) can be adjusted by moving the lower scraper shaft (412) up and down.

[0098] The aforementioned scraper component (450) includes: a scraper fixing component (420) which is horizontally arranged and whose inner end is fixed to the position adjustment component (460); an outer scraper component (430) which is bent downward from the radial outer end of the scraper fixing component (420) and is in close contact with the inner surface of the bowl (200); and a scraper support component (440) which vertically connects the scraper fixing component (420) and the outer scraper component (430) to support the scraper fixing component (420) and the outer scraper component (430).

[0099] The aforementioned scraper fixing part (420) is positioned radially outward relative to the rotation axis (C). The aforementioned scraper fixing part (420) is horizontally arranged and can move radially along the position adjustment assembly (460) and be fixed on the position adjustment assembly (460).

[0100] The aforementioned scraper holder (420) is arranged such that its radially outer end (421) is inclined relative to the radial direction. In this embodiment, the outer end (421) forms a scraper tilt angle (S) greater than 45 degrees and less than 90 degrees radially relative to the axis of rotation (C).

[0101] The aforementioned outer scraping portion (430) includes: an outer vertical portion (431) that is connected to the outer end (421) and extends downward; and an outer curved portion (432) that is formed at the lower end of the outer vertical portion (431) and bends along the direction of the rotation axis (C).

[0102] When viewed from the top, the outer vertical portion (431) forms a scraper tilt angle (S).

[0103] The material or agitated material on the inner surface of the cylindrical part (220) can be easily scraped off by the outer vertical part (431) set with the above-mentioned scraper tilt angle (S).

[0104] The aforementioned outer curve portion (432) is formed to correspond to the curvature of the bowl-shaped portion (210).

[0105] The upper end of the aforementioned outer curved portion (432) is connected to the lower end of the aforementioned outer vertical portion (431), and the lower end is positioned at the edge of the aforementioned discharge port (215). The lower end of the aforementioned outer curved portion (432) is positioned so as not to encroach on the discharge port (215).

[0106] The aforementioned scraper support (440) includes a first scraper support (441) with its upper end fixed to the scraper fixing part (420) and a second scraper support (442) with its lower end fixed to the outer scraper part (430) and supporting the outer curved part (432).

[0107] The snap-fit ​​part (445) is threadedly connected to the lower part of the first scraper support (441) and the upper part of the second scraper support (442), and is used to adjust the gap between the lower part of the first scraper support (441) and the second scraper support (442).

[0108] Both the first scraper support (441) and the second scraper support (442) can be formed in the shape of a rod.

[0109] The lower outer surface of the first scraper support (441) is threaded, and the upper outer surface of the second scraper support (442) is threaded.

[0110] The aforementioned latching part (445) is screwed to the lower end of the first scraper support part (441), and the aforementioned latching part (445) can move up and down along the first scraper support part (441). The aforementioned latching part (445) can be fixedly connected to the upper part of the second scraper support part (442) by screws.

[0111] Therefore, the buckle portion (445) can support the second scraper support portion (442), suppress the sagging of the outer curved portion (432), and precisely adjust the gap with the bowl-shaped portion (210).

[0112] When mixing a large amount of material, the outer scraper section (430) may be subjected to a large load, while the scraper support section (440) has the characteristic of being able to stably support the outer scraper section (430).

[0113] The aforementioned position adjustment assembly (460) includes: a position adjustment connecting part (461) connected to the lower end of the lower scraper shaft (412); a lower adjustment support part (462) extending radially outward from the position adjustment connecting part (461) relative to the rotation axis (C) and supporting the scraper fixing part (420); an upper adjustment support part (463) disposed above the lower adjustment support part (462) and making the scraper fixing part (420) in close contact with the lower adjustment support part (462); and a position adjustment handle (465) making the upper adjustment support part (463) in close contact with the lower adjustment support part (462).

[0114] In this embodiment, the lower adjustment support (462) is located below the scraper fixing part (420), and the upper adjustment support (463) is located above.

[0115] The aforementioned position adjustment handle (465) is inserted into the upper adjustment support (463), the scraper fixing part (420), and the lower adjustment support (462), and is respectively fastened to the upper adjustment support (463) and the lower adjustment support (462).

[0116] The scraper fixing part (420) can be positioned on the upper adjusting support part (463) and the lower adjusting support part (462) and then fixed after sliding radially along the rotation axis (C).

[0117] The aforementioned position adjustment handle (465) is located above the upper adjustment support (463). The worker can rotate the position adjustment handle (465) to make the upper adjustment support (463) and the lower adjustment support (462) come into close contact.

[0118] When the scraper fixing member (420) moves radially, the position adjustment handle (465) can be rotated in the opposite direction to release the contact between the upper adjustment support member (463) and the lower adjustment support member (462).

[0119] The valve assembly (600) includes: a valve flange (610) connected to a cup-shaped portion (210) to form a discharge port (215); a valve body (620) connected to the lower side of the valve flange (610); a valve ball (650) rotatably mounted in the valve body (620) and configured to open and close the discharge port (215) by rotating up and down; a drive actuator (630) disposed in the valve body (620) and configured to rotate the valve ball (650); and a support shaft (640) disposed on the opposite side of the drive actuator (630) relative to the valve ball (650) to provide a center of rotation for the valve ball (650).

[0120] The valve assembly (600) further includes valve packing (660) which is fixed to at least one of the valve body (620) or valve flange (610) and in close contact with the upper surface of the valve ball (650) to seal the edge of the discharge port (215).

[0121] In this embodiment, a stepper motor is used as the drive actuator (630). The drive actuator (630) rotates the valve ball (650) by 90 degrees to open and close the discharge port (215).

[0122] The aforementioned drive actuator (630) includes a drive shaft (635) that is inserted into a valve ball (650) to provide driving force. The drive shaft (635) is cylindrical, and in this embodiment, it is square-column shaped.

[0123] The aforementioned drive shaft (635) is horizontally arranged. The aforementioned drive shaft (635) is orthogonal to the rotation axis (C). The aforementioned drive shaft (635) meshes with the valve ball (650) in the rotational direction, thereby causing the valve ball (650) to rotate.

[0124] The aforementioned support shaft (640) is horizontally arranged and aligned with the drive shaft (635). The aforementioned support shaft (640) is orthogonal to the axis of rotation (C). The aforementioned support shaft (640) and drive shaft (635) are mounted on opposite sides with the valve ball (650) as the center. The aforementioned support shaft (640) is formed in a cylindrical shape, and additional bearings can be placed on its outer surface to minimize friction.

[0125] The valve flange (610) is in close contact with the lower part of the cup-shaped body (210), and when viewed from above, the center of the plane is located on the axis of rotation (C).

[0126] Viewed from above, the outlet (215) is circular.

[0127] The valve flange (610) has a flange opening with a diameter slightly smaller than that of the outlet (215). When viewed from above, the flange opening has a diameter slightly smaller than that of the outlet (215).

[0128] The valve flange (610) includes a flange body (611) fixedly installed at the lower end of the bowl-shaped portion (210), and a flange extension (612) that protrudes radially inward toward the rotation axis (C) from the flange body (611) and forms a flange opening that penetrates vertically inside.

[0129] The valve flange (610) mentioned above is generally annular, and the flange opening is circular.

[0130] The thickness of the flange extension (612) is made thinner than the thickness of the flange body (611).

[0131] The valve flange (610) further includes a flange groove (613) recessed radially outward on the inner surface of the flange body (611). The valve packing (660) is assembled in the flange groove (613) and forms a mutual fit with the valve packing (660) in the vertical direction.

[0132] A flange fastening hole (not shown) is formed on the flange body (611) in the vertical direction, through which fastening components can be fastened to the valve body (620) by passing through the flange fastening hole.

[0133] The flange body (611) and flange extension (612) overlap with the edge of the discharge port (215) to reduce the size of the discharge port (215).

[0134] The thickness of the flange extension (612) is made thinner than that of the flange body (611), so that while supporting the valve ball (650), the valve packing (660) can be firmly supported by elastic deformation.

[0135] The valve body (620) includes a valve body support (621) that is in close contact with the lower surface of the flange (611), a valve body housing (622) that extends downward from the valve body support (621), and a valve body hollow space (625) formed inside the valve body housing (622) and in which the valve ball (650) is placed.

[0136] The valve body (620) is connected to the lower end of the valve flange (610) and supports the valve flange (610).

[0137] The valve body support (621) is formed in a ring shape and assembled on the bottom surface of the flange body (611).

[0138] The valve body housing (622) is formed in a cylindrical shape, and a hollow valve body space (625) is formed inside the valve body housing (622). The hollow valve body (625) is formed in a vertical direction and has openings on the top and bottom sides.

[0139] The valve ball (650) rotates, causing the hollow body (625) to open and close.

[0140] The valve ball (650) described above may be part of a sphere. In this embodiment, the valve ball (650) is shaped like a table. The center of the sphere includes the valve ball (650).

[0141] The truncated sphere in the image above is the shape formed by cutting a sphere into two planes, with the cut surfaces being flat and parallel.

[0142] The valve ball (650) includes a valve ball (651) formed in the shape of a truncated sphere, a first spherical plane (652a) forming the plane of the valve ball (651), a second spherical plane (652b) arranged parallel to the first spherical plane (652a), and a spherical recess (655) formed to penetrate the first spherical plane (652a) and the second spherical plane (652b).

[0143] The center of the spherical surface of the valve ball (650) is located within the aforementioned ball cavity (655). The center of the spherical body of the aforementioned valve ball (650) is located on the rotation axis (C).

[0144] The aforementioned spherical cavity (655) is cylindrical.

[0145] The valve ball (650) further includes: a first shaft groove (653) formed recessed towards the center of the outer surface of the valve ball (651), into which a drive shaft (635) is inserted; and a second shaft groove (654) formed recessed towards the center of the outer surface of the valve ball (651), into which a support shaft (640) is inserted, and the second shaft groove (654) is located opposite to the first shaft groove (653).

[0146] The drive shaft (635) is inserted into the first bearing seat (653) and assembled. The first bearing seat (653) is formed in a prism shape, and in this embodiment, it is formed in a quadrangular prism shape.

[0147] When the drive shaft (635) rotates, it meshes with each other in the first shaft groove (653) along the direction of rotation. The first shaft seat (653) and the second shaft seat (654) are orthogonal to the axis of rotation (C).

[0148] The first journal (653) and the second journal (654) are disposed opposite to each other with respect to the center of the ball. The first journal (653) is recessed toward the second journal (654), and the second journal (654) is recessed toward the first journal (653).

[0149] The second shaft groove (654) is cylindrical, and the support shaft (640) is inserted into the second shaft groove (654).

[0150] The aforementioned spherical hole (655) has a first spherical plane (652a) on one side and a second spherical plane (652b) on the other side.

[0151] When the aforementioned spherical cavity (655) faces the outlet (215), the stirred material in the bowl-shaped space (201) can be discharged into the container.

[0152] When the aforementioned ball cavity (655) is placed horizontally, the outer surface of the valve ball (651) closes the discharge port (215). In particular, since the outer surface of the valve ball (651), which is formed as part of the ball, protrudes towards the upper side of the discharge port (215), leakage of the compound can be minimized.

[0153] The outer surface of the valve ball (651) protrudes into the bowl-shaped space (201) through the outlet (215), and contact during stirring is prevented as the impeller assembly (300) and scraper assembly (400) rotate along the outer side of the valve ball (651).

[0154] In particular, since the valve ball (651) is spherical, the material that gathers downwards can move outwards by its own weight at the upper apex of the valve ball (651). During this process, the lower part of the impeller (324) and the lower part of the outer curved surface (432) can come into contact with the material while rotating, thus having the advantages of improving stirring efficiency and shortening stirring time.

[0155] The valve packing (660) includes a packing body (665) that is in close contact with the valve flange (610), and an inner surface (661) of the packing body (665) that is disposed on the inner surface of the packing body (665) and in close contact with the outer surface of the valve ball (651).

[0156] The valve seal (660) is made of an elastic synthetic resin material.

[0157] The valve packing (660) is positioned above the drive shaft (635) and the support shaft (640). Even when the valve ball (650) rotates, it remains in contact with the outer surface of the spherical valve ball (651), thus providing the property of preventing compound leakage.

[0158] The inner surface of the packing (661) corresponds to the radius of curvature of the valve ball (650).

[0159] The inner surface of the filler (661) is concave from bottom to top.

[0160] The inner surface of the filler (661) can have a spherical shape.

[0161] The inner surface (661) of the filler is located at the upper center of the sphere.

[0162] The valve packing (660) further includes a discharge packing section (662) which protrudes upward from the inner edge of the packing body (665) and is in close contact with the inner edge of the discharge port (215).

[0163] The aforementioned discharge sealing portion (662) is radially disposed inside the aforementioned flange extension portion (612). The inner end of the discharge packing portion (662) is located radially outside the ball cavity (655) so as not to obstruct the flow of the stirring material into the ball cavity (655).

[0164] The aforementioned outlet packing section (662) does not occupy part of the edge of the aforementioned outlet (215), but is in close contact with the valve ball (650), thus having the characteristic of minimizing leakage.

[0165] The valve packing (660) protrudes radially outward from the outer surface of the packing body (665) and is fitted into the flange groove (613). It also includes a packing fitting (663). The packing fitting (663) can form a vertical mating with the valve flange (610).

[0166] In this embodiment, when the stirring device forms a ball cavity (655) by rotating up and down, the stirred material can be discharged downward by its own weight. Therefore, the staff does not need to scrape off the stirred material remaining in the bowl-shaped object (200), which can avoid the risk of safety accidents caused by this.

[0167] The stirring apparatus according to this embodiment has the characteristic that the stirring material remaining in the bowl (200) can continue to move downward by its own weight because the scraper assembly (400) can continue to operate even when the valve assembly (600) is open.

[0168] Although specific embodiments have been described in the detailed description of the invention, various modifications can certainly be made without departing from the scope of the invention. Therefore, the scope of the invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of those claims.
