[0003] Technology field

[0004] The present invention relates to a tumbler device and a source coating system.

[0005] Patent Document 1 discloses a meat snack manufacturing device having a seasoning tumbler that processes roasted food with seasoning oil using a pellet sheet containing ground meat.

[0006] In the seasoning tumbler of Patent Document 1, food residue and seasoning oil can harden into sludge and adhere to the inner surface of the tumbler. In such cases, for example, the tumbler must be periodically stopped to remove the sludge from the inner surface. Consequently, it is difficult to improve the tumbler's operating rate.

[0010] The present invention aims to provide a tumbler device and a source coating system capable of effectively removing sludge from the inner wall surface of a tumbler body.

[0011] For example, a tumbler device may include a tumbler body having a cylindrical body with a centerline extending laterally, a tumbler inlet opening at one end in a direction of a centerline parallel to the centerline, a tumbler outlet opening at the other end in the direction of the centerline, a tumbler inner surface connecting the tumbler inlet and the tumbler outlet, and a screw wall protruding inwardly from the tumbler inner surface and extending spirally from the tumbler inlet to the tumbler outlet along the tumbler inner surface, a tumbler rotator that rotates the tumbler body around the centerline, and a scraper body having a front end that contacts the tumbler inner surface at a position adjacent to at least a portion of the screw walls extending spirally toward the tumbler outlet.

[0012] For example, a sauce coating system may include a tumbler device additionally having a sauce coating unit, and a weight scale for measuring the weight of a food product supplied to the tumbler body, wherein the sauce coating unit may include a spraying unit for spraying a food product sauce composition to the food product supplied to the tumbler body, a pump for discharging the food product sauce composition and supplying it to the spraying unit, a discharge amount measuring unit for measuring the weight of the food product sauce composition discharged from the pump, and a control device for controlling the operation of the pump to adjust the supply amount of the food product sauce composition based on the weight of the food product by referring to a recipe in which a relationship between the weight of the food product sauce composition and the weight of the food product is stipulated and stored in a memory in advance.

[0013] According to the present invention, when the tumbler body is driven to rotate, food introduced from the tumbler inlet is supported on the inner surface of the tumbler and returned to the tumbler outlet by the screw wall. Here, sludge originating from the food, particularly when a food sauce composition is attached to the food within the tumbler body, sludge originating from the food and the food sauce composition is likely to adhere to the inner surface of the tumbler.

[0014] However, the tumbler device according to the present invention has a scraper, and the scraper is in contact with the inner surface of the tumbler at a position adjacent to the tumbler outlet side with respect to at least some of the screw walls extending in a spiral shape. As a result, the scraper spirally scrapes the inner surface of the tumbler along the rotating screw wall accompanying the rotation of the tumbler body. Therefore, adhesion of sludge to the inner surface of the tumbler is suppressed, and thus the frequency of cleaning, such as manually removing sludge from the inner surface of the tumbler, can be reduced. Therefore, since sludge can be effectively removed from the inner surface of the tumbler body, the operating rate of the tumbler device can be improved.

[0040] Hereinafter, a tumbler device and a source coating system related to one embodiment of the present invention will be described with reference to the attached drawings. The following description is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.

[0041] [First embodiment]

[0042] Fig. 1 is a schematic diagram of a source coating system (1) related to the first embodiment of the present invention. As shown in Fig. 1, the source coating system (1) has a tumbler device (6) for coating a food source composition (S) on a food (F), a food loading device (2) for loading the food (F) into the tumbler device (6), a food discharge device (5) for loading the coated food (F1) loaded from the tumbler device (6), and a control device (50) for controlling the operation of the source coating system (1). The food (F) may be, for example, a cooked food such as fried chicken.

[0043] The food loading device (2) has a transport device (3) for transporting food (F) and a weight scale (4) for measuring the weight of the food (F) on the transport device (3). The weight of the food (F) transported to the tumbler device (6) is continuously measured by the weight scale (4). The measurement results by the weight scale (4) are input to the control device (50).

[0044] The tumbler device (6) has a cylindrical tumbler body (10) with a center line (O1) extending laterally, a tumbler frame (7) that supports the tumbler body (10) so as to be rotatable about the center line (O1), a tumbler rotator (8) that rotates the tumbler body (10) about the center line (O1), a source coating unit (20), and a scraper unit (30) (see FIG. 2).

[0045] In the following description, the direction parallel to the center line (O1) of the tumbler body (10) is referred to as the X direction, and among the X directions, the direction toward the food loading device (2) (i.e., the upstream side in the return direction) is referred to as the X1 side, and the direction toward the food discharging device (5) (i.e., the downstream side in the return direction) is referred to as the X2 side. In addition, in the present embodiment, the X1 side is sometimes referred to as the front side of the tumbler device (6), and the X2 side is sometimes referred to as the rear side of the tumbler device (6).

[0046] Additionally, the left-right direction and the up-down direction when the tumbler device (6) is viewed from the X1 side are referred to as the Y direction and the Z direction of the tumbler device (6), respectively. In the Y direction, the left side when viewed from the X1 side is referred to as the Y1 side, and the right side thereof is referred to as the Y2 side. In the Z direction, the upper side is referred to as the Z1 side, and the lower side is referred to as the Z2 side.

[0047] The tumbler frame (7) supports the tumbler body (10) so that the center line (O1) is inclined toward the Z2 side as it moves from the X1 side to the X2 side. For example, the inclination angle (θ) of the center line (O1) with respect to the horizontal line may be 4° or more and 6° or less. In the present embodiment, the inclination angle (θ) of the center line (O1) is 5°.

[0048] The tumbler rotator (8) is, for example, an electric motor, and has a rotating output shaft (8a), and the rotation of the output shaft (8a) is controlled by a control device (50). The output shaft (8a) is provided with a driving part (8b) that is engaged with, for example, the outer surface of the tumbler body (10). The tumbler body (10) is driven to rotate around the center line (O1) through the outer surface by the driving part (8b). The driving part (8b) may be anything that can transmit the rotation of the output shaft (8a) by engaging with the outer surface of the tumbler body (10), and may be, for example, a driving gear or a driving roller. For example, the tumbler rotator (8) rotates the tumbler body (10) at a rotation speed of 3 rpm or more and 8 rpm or less.

[0049] The source coating unit (20) has a tank (21) in which a food source composition (S) is stored, a pump (22) which is connected at one end to the tank (21) and pressurizes the food source composition (S) flowing in from the tank (21) to a predetermined pressure and discharges it, a discharge amount measuring unit (23) which measures the flow rate of the food source composition (S) discharged from the pump (22), and a spraying unit (24) which is located inside the tumbler body (10) and sprays the food source composition (S) discharged from the pump (22).

[0050] The source coating unit (20) additionally has a heater (25) that heats the food source composition (S) stored in the tank (21) to a predetermined temperature. By the heater (25), the food source composition (S) is maintained at a viscosity suitable for spraying by the spray unit (24).

[0051] The pump (22) is controlled by a control device (50) to discharge a food sauce composition (S) at a desired discharge amount. The discharge amount measuring unit (23) measures the weight per unit time of the food sauce composition (S) discharged from the pump (22). The measurement result by the discharge amount measuring unit (23) is input to the control device (50).

[0052] An air compressor (26) that supplies compressed air is connected to the injection unit (24), so that compressed air is introduced when the food source composition (S) is injected.

[0053] Fig. 2 is a perspective view schematically showing a tumbler body (10) and a scraper unit (30). In Fig. 2, for convenience of explanation, the tumbler body (10) is shown as a semi-cylindrical body with one radial side deleted. As shown in Fig. 2, the tumbler body (10) has a cylindrical tumbler main wall portion (11), and a screw wall (12) and a baffle (13) that protrude inward from a tumbler inner surface (11a), which is an inner surface of the tumbler main wall portion (11).

[0054] The tumbler main wall portion (11) has a tumbler inlet (11b) (see Fig. 1) that opens toward the X1 side in the X direction and a tumbler outlet (11c) that opens toward the X2 side. Referring also to Fig. 1, the tumbler main wall portion (11) has an end portion on the X1 side whose diameter decreases toward the X1 side, so that the tumbler inlet (11b) is smaller than the tumbler outlet (11c). The tumbler inner surface (11a) extends from the tumbler inlet (11b) to the tumbler outlet (11c).

[0055] The screw wall (12) extends in a spiral shape around the center line (O1) from the screw start portion (12a) (see Fig. 6) near the tumbler inlet (11b) along the tumbler inner surface (11a) toward the screw end portion (12b) (see Fig. 6) near the tumbler outlet (11c). When the tumbler body (10) is viewed from the X1 side, the screw wall (12) extends counterclockwise around the center line (O1) at a predetermined pitch (Z).

[0056] When the tumbler body (10) rotates clockwise (R) when viewed from the X1 side around the center line (O1), the downstream side portion of the screw wall (12) appears sequentially at a specific circumferential position of the tumbler main wall (11), so that the screw wall (12) appears to move toward the X2 side. That is, the food (F) on the X2 side of the screw wall (12) is returned to the X2 side by the screw wall (12) moving toward the X2 side at the specific circumferential position.

[0057] The pitch (Z) and radial height (H1) of the screw wall (12) are appropriately set according to the size, quantity, and conveying speed of the food (F) being conveyed, and the coating specifications of the food source composition (S). The height (H1) of the screw wall (12) is set so as to overlap at least a portion of the scraper body (31) in the expanded configuration (C2) as shown in Fig. 5 when viewed in the X direction.

[0058] The baffles (13) are installed at multiple locations spaced at equal angles around the center line (O1) on the inner surface of the tumbler (11a), and each extends in a straight line in the X direction along the inner surface of the tumbler (11a). The baffles (13) have a triangular cross-sectional shape perpendicular to the center line (O1). According to the baffles (13), the food (F) is moved in the circumferential direction along with the rotation of the tumbler body (10) and is widely distributed in the circumferential direction, thereby suppressing the food (F) from being positioned unevenly around the lower end of the inner surface of the tumbler (11a).

[0059] The radial height (H2) and circumferential width (W1) of the baffle (13) are appropriately set according to the size, quantity, and conveying speed of the food (F) being conveyed, and the coating specifications of the food source composition (S). The radial height (H2) of the baffle (13) is equal to or less than the radial height (H1) of the screw wall (12), and preferably is lower than the radial height (H1).

[0060] The scraper unit (30) has a scraper body (31) that scrapes the inner surface (11a) of the tumbler, a scraper translation guide (40) that guides translational movement of the scraper body (31) in the X direction, a scraper translation device (445) that translates the scraper body (31) in the X direction, a scraper containment guide (47) that converts the scraper body (31) from a deployment configuration (C2) to a storage configuration (C1), and a scraper deployment device (49) that converts the scraper body (31) from a storage configuration (C1) to a deployment configuration (C2).

[0061] Fig. 3 is an enlarged perspective view showing the periphery of the scraper body (31) in the containment configuration (C1). Figs. 4 and 5 are rear views of the scraper unit (30) as seen from the X2 side. Fig. 4 shows, with a solid line, a case where the scraper body (31) is in the containment configuration (C1). Fig. 5 shows, with a solid line, a case where the scraper body (31) is in the expanded configuration (C2). As shown in Figs. 4 and 5, the scraper unit (30) is positioned, as a whole, on the Y2 side and the Z1 side with respect to the center line (O1) of the tumbler body (10).

[0062] The scraper body (31) has an L-shaped scraper base (32) as shown in FIGS. 4 and 5, and a scraper (33) whose end on the Z2 side is rotatably connected to the scraper base (32).

[0063] The scraper base (32) has a base first part (32a) extending in the Z direction and a base second part (32b) extending horizontally from the Z2-side end of the base first part (31a) to the Y2 side. The base first part (32a) is fixed to the scraper translation guide (40) on the side surface on the Y1 side.

[0064] The second base part (32b) has a rotation support part (35) that supports the scraper (33) so that it can rotate around the rotation axis (O2) extending in the X direction at the tip end. The rotation support part (35) may be a cylindrical hole part or a cylinder-shaped rotation axis part. In addition, the second base part (32b) has a rotation positioning pin (36) that protrudes in the X direction below the rotation support part (35). The rotation positioning pin (36) contacts the lower end of the scraper (33) from the Y2 side to position the scraper (33) so as to rotate around the rotation axis (O2), thereby positioning the scraper body (31) in the storage structure (C1).

[0065] As shown in Fig. 4, the scraper (33) has a first arm portion (33a) extending generally in the vertical direction when the scraper body (31) is in the containment configuration (C1), and a second arm portion (33b) curved toward the Y1 side from the tip of the first arm portion (33a). As shown in Fig. 5, the second arm portion (33b) extends generally in the vertical direction when the scraper body (31) is in the deployment configuration (C2).

[0066] As shown in Fig. 3, the first arm portion (33a) is rotatably supported on a rotation support portion (35) at the base portion. The first arm portion (33a) has a rotation stopper (38) at the Z2-side end that contacts the rotation positioning pin (36) from the Y1 side when the scraper body (31) rotates from the deployment configuration (C2) to the storage configuration (C1).

[0067] In the present embodiment, the first arm part (33a) and the second arm part (33b) are installed as a pair in the X direction with the scraper base (32) therebetween. Between the pair of first arm parts (33a), a storage roller (37) is supported so as to be rotatable about a rotational axis (O3) extending parallel to the first arm part (33a). The storage roller (37) protrudes toward the Y2 side more than the first arm part (33a) when viewed in the X direction. When the scraper main body (31) is in the deployed configuration (C2), the storage roller (37) is displaced toward the Z1 side by rolling on the scraper storage guide (47), thereby generating a rotational moment in the scraper (33) about the rotational axis (O2) in the direction away from the tumbler inner surface (11a).

[0068] The scraper (33) additionally has a scraper shaft portion (33c) connecting a pair of female second parts (33b) in the X direction, a scraper mounting leg portion (33d) extending from the scraper shaft portion (33c) toward the tumbler inner surface (11a), and a scraping portion (33e) fixed to the tip of the scraper mounting leg portion (33d).

[0069] The scraper shaft portion (33c) is fixed to each of the pair of female second portions (33b). The scraper mounting leg portion (33d) extends in a direction orthogonal to the extending direction of the female second portion (33b) when viewed in the X direction. Specifically, when the scraper main body (31) is in the deployed configuration (C2) (see Fig. 5), the female second portion (33b) extends in the Z direction, and the scraper mounting leg portion (33d) extends from the female second portion (33b) toward the Y2 side.

[0070] The scraping portion (33e) is a rectangular plate member when viewed from the front, and when viewed in the X direction, the corner portion on the inner surface (11a) of the tumbler among the ends opposite to the tumbler rotation direction (R), which is the rotational direction of the tumbler, is configured at an acute angle. As shown in Fig. 2, the dimension (L1) of the scraping portion (33e) in the X direction is shorter than the dimension (L0) (see Fig. 2) between adjacent portions in the X direction among the screw walls (12) extending in a spiral shape.

[0071] As shown in Fig. 5, when the scraper body (31) is in the expanded configuration (C2), the tip of the scraping portion (33e) is located on a line inclined at about 45° toward the Z1 side with respect to a straight line extending from the center line (O1) of the inner surface of the tumbler (11a) toward the Y2 side (above the left diagonal of the center line (O1) in Fig. 5).

[0072] In the present embodiment, when the scraper body (31) is in the deployed configuration (C2), when viewed in the X direction, the front end portion of the second arm portion (33b) and the entire scraping portion (33e) overlap the screw wall (12). Accordingly, the screw wall (12), which moves toward the X2 side in accordance with the rotation of the tumbler body (10), pushes the scraper body (31) from the X1 side to the X2 side, thereby moving the scraper body (31) toward the X2 side.

[0073] Accordingly, the scraping section (33e) sequentially scrapes between the screw walls (12) adjacent to each other in the X direction on the inner surface (11a) of the tumbler. Therefore, scraping by the scraping section (33e) is performed on the inner surface (11a) of the tumbler along with the rotation of the tumbler body (10).

[0074] As shown in Fig. 4, when the scraper body (31) is in the containment configuration (C1), when viewed in the X direction, the scraper body (31) is retracted inwardly with respect to the screw wall (12) as a whole. Therefore, when the scraper body (31) is in the containment configuration (C1), the scraper body (31) can be moved in the X direction without interfering with the screw wall (12) of the tumbler body (10).

[0075] When the scraper body (31) is in the containment configuration (C1), a clockwise rotational moment is generated in the scraper (33) about the rotational axis (O2), and the position is determined in the rotational direction by the rotational positioning pin (36). On the other hand, as shown in Fig. 5, when the scraper body (31) is in the deployment configuration (C2), a counterclockwise rotational moment is generated in the scraper (33) about the rotational axis (O2), and the scraping portion (33e) is in contact with the tumbler inner surface (11a), thereby determining the position in the rotational direction.

[0076] That is, when the scraper body (31) is positioned between the containment configuration (C1) and the deployment configuration (C2), a neutral configuration (C0) exists in which no rotational moment is generated in either direction about the rotation axis (O2) of the scraper (33).

[0077] As shown in Fig. 2, the scraper translation guide (40) extends in the X direction on the inside of the tumbler body (10), and both ends in the X direction are fixed to the tumbler frame (7) via brackets that are not shown. Referring also to Fig. 3, in the present embodiment, the scraper translation guide (40) is a linear guide and has a guide rail (41) extending in the X direction, and a carriage (42) guided by the guide rail (41) and moving in the X direction. The carriage (42) is mounted on the side surface on the Y2 side with the base first part (32a) of the scraper body (31).

[0078] As shown in Fig. 2, the scraper translation device (44) extends in the X direction on the inside of the tumbler body (10), and both ends in the X direction are fixed to the tumbler frame (7) via brackets that are not shown. The scraper translation devices (44) are arranged adjacent to each other on the Z1 side of the scraper translation guide (40). Referring also to Fig. 3, in the present embodiment, the scraper translation device (44) is a pneumatic double-acting rodless cylinder, and has a cylinder body (45) and a moving body (46) that moves in the X direction on the side surface on the Y2 side of the cylinder body (45) by air supplied to the cylinder body (45).

[0079] The moving body (46) is not connected to the scraper body (31) and is located on the X2 side with respect to the scraper body (31). As indicated by the dashed line in FIGS. 4 and 5, the moving body (46) is positioned so as to partially overlap the base first part (32a) of the scraper body (31) when viewed from the X2 side. By moving the moving body (46) toward the X1 side, the moving body (46) pushes the base first part (32a) toward the X1 side, thereby moving the scraper body (31) toward the X1 side.

[0080] Fig. 6 is a front view schematically showing a scraper unit (30), and for the convenience of explanation, a perspective view of the tumbler body (10) as seen from the front is also shown. In Fig. 6, a part of the tumbler body (10) is shown in a broken state. As shown in Fig. 6, the moving body (46) moves between a first position (PS1) on the X2 side indicated by a solid line and a second position (PS2) on the X1 side indicated by a double-dotted line.

[0081] The first position (PS1) is set so that the moving body (46) is positioned on the X2 side relative to the scraper body (31) at the scraping end position (Q2). The second position (PS2) is set so that the moving body (46) contacts the scraper body (31) at the scraping start position (Q1) from the X2 side.

[0082] The scraping start position (Q1) and the scraping end position (Q2) each refer to the X-direction position of the scraper body (31). Specifically, the scraping start position (Q1) refers to the X-direction position of the scraper body (31) at which the scraper body (31) starts scraping the inner surface (11a) of the tumbler. When the scraper body (31) is at the scraping start position (Q1), the scraper body (31) is located on the X2 side relative to the screw start portion (12a) of the screw wall (12). More specifically, at the scraping start position (Q1), the scraper body (31) is located between a portion of the screw wall (12) located near the screw start portion (12a) in the X-direction and a portion of the screw wall (12) adjacent thereto on the X2 side.

[0083] The scraping end position (Q2) refers to the X-direction position of the scraper body (31) at which the scraper body (31) finishes scraping the inner surface (11a) of the tumbler. When the scraper body (31) is at the scraping end position (Q2), the scraper body (31) is located on the X2 side relative to the screw end portion (12b) of the screw wall (12). More specifically, at the scraping end position (Q2), the scraper body (31) is located between a portion of the screw wall (12) located near the screw end portion (12b) and the tumbler outlet (11c) in the X-direction.

[0084] As shown in Fig. 6, the scraper storage guide (47) is fixed to the tumbler frame (7) via a bracket (not shown). The scraper storage guide (47) is installed corresponding to the scraper main body (31) located at the scraping end position (Q2). The scraper storage guide (47) is installed at a position where the end on the X1 side contacts the storage roller (37) of the scraper main body (31) in the deployment configuration (C2) from the Z2 side. The scraper storage guide (47) extends in a direction inclined toward the Z1 side toward the X2 side.

[0085] Referring also to FIG. 5, the scraper containment guide (47) is set to displace the containment roller (37) toward the Z1 side until a rotational moment due to its own weight is generated about the rotational axis (O2) in the direction away from the tumbler inner surface (11a) of the scraper (33), i.e., until the neutral configuration (C0) is exceeded. Specifically, the scraper containment guide (47) is set to have a displacement amount toward the Z1 side so that the scraper (33) rotates beyond the neutral configuration (C0) in the expanded configuration (C2) while the scraper body (31) is pushed toward the X2 side by the screw wall (12), i.e., while the rotating scraper (33) is overlapped in the X direction by the screw wall (12). Since the containment roller (37) moves on the scraper containment guide (47), the sliding resistance in the engagement of the scraper (33) and the scraper containment guide (47) is small.

[0086] As shown in Fig. 2, the scraper deployment device (49) is fixed to the tumbler frame (7) via a bracket (not shown). The scraper deployment device (49) is installed corresponding to the scraper body (31) located at the scraping start position. In the present embodiment, the scraper deployment device (49) is an air cylinder having a rod (49a) that can protrude and retract in the Y direction. The rod (49a) of the scraper deployment device (49) faces the Y2 side with respect to the scraping section (33e).

[0087] As shown in Fig. 4, the scraper deployment device (49) pushes the scraping portion (33e) of the scraper main body (31) in the storage configuration (C1) toward the Y2 side by protruding the rod (49a) toward the Y2 side. The scraper deployment device (49) is set to displace the scraper (33) toward the Y2 side until a rotational moment due to its own weight is generated about the rotational axis (O2) in the direction away from the tumbler inner surface (11a) of the scraper (33), i.e., until the neutral position is exceeded.

[0088] As shown in Fig. 6, when the scraper deployment device (49) converts the scraper body (31) from the storage configuration (C1) to the deployment configuration (C2), the tumbler body (10) is stopped so that the rotational position about the center line (O1) becomes the scraping start rotational position (R0). At the scraping start rotational position (R0), the screw wall (12) of the tumbler body (10) is set to a rotational position that does not overlap in the radial direction of the tumbler body (10) with respect to the scraper body (31) located at the scraping start position (Q1).

[0089] As described above, at the scraping start position (Q1), the scraper body (31) is positioned at an X-direction position corresponding to the portion of the screw wall (12) located near the screw start portion (12a) and the portion of the screw wall (12) adjacent thereto on the X2 side, so the scraper body (31) is deployed directly on the X2 side near the screw start portion (12a) among the screw walls (12).

[0090] The tumbler device (6) additionally includes a first sensor (16) and a second sensor (17). The first sensor (16) is installed at the X2-side end of the scraper translation device (44) and has a detection portion (16a) that contacts the scraper body (31) that has reached the scraping end position. The first sensor (16) detects that the scraper body (31) has reached the scraping end position when the detection portion (16a) is pushed toward the X2 side by the scraper body (31). The detection result by the first sensor (16) is input to the control device (50).

[0091] The second sensor (17) is installed on the outer circumference of the tumbler body (10) and has a detection unit (17a) that detects when the rotational position of the tumbler body (10) becomes the scraping start rotation position (R0). On the tumbler body (10), a detection unit (10a) is installed at a position opposite to the detection unit (17a) of the second sensor (17) when the rotational position of the tumbler body (10) becomes the scraping start rotation position (R0). The detection unit (17a) of the second sensor (17) detects the detection unit (10a) of the tumbler body (10). The detection result by the second sensor (17) is input to the control device (50).

[0092] In addition, as shown in FIGS. 4 and 5, the tumbler device (6) additionally has a sludge receiver (18) on the Z2 side of the scraper body (31). The sludge receiver (18) extends in the X direction along the inside of the tumbler body (10) at least in the X direction range in which the scraping of the inner surface (11a) of the tumbler is performed by the scraper body (31). The sludge receiver (18) is formed in a fan shape (also called a funnel shape) in which the cross-sectional shape as viewed in the X direction narrows toward the Z2 side. Hot water is supplied to the sludge receiver (18), and the sludge scraped off by the scraper body (31) is received and discharged to the outside of the tumbler body (10) by the hot water.

[0093] As shown in Fig. 1, the control device (50) is configured by a known computer or circuit having a memory (51) such as an HDD or SSD, a central processing unit (52), a memory, and an input / output device. The memory unit (51) stores software for performing each function of the source coating system (1) and a recipe related to coating. The processing unit (52) has a food supply control unit (53), a tumbler rotation control unit (54), a source supply amount determination unit (55), a source coating unit control unit (56), and a scraper unit control unit (57).

[0094] The food supply control unit (53) controls the food loading device (2) to control the amount of food (F) supplied to the tumbler body (10). In addition, the food supply control unit (53) continuously acquires the weight of the food (F) supplied to the tumbler body (10) by the weight scale (4).

[0095] The tumbler rotation control unit (54) controls the rotation speed of the tumbler body (10) through the tumbler rotator (8). After the scraper unit control unit (57) determines that the scraper body (31) has reached the scraping start position (Q1), the tumbler rotation control unit (54) stops the tumbler body (10) at the scraping start rotation position (R0) based on the detection result of the second sensor (17).

[0096] The source supply amount determination unit (55) determines an appropriate discharge amount of the food source composition (S) by referring to the recipe read from the memory unit (51) based on the weight of the food (F) measured by the weight scale (4).

[0097] When operating the source coating unit (20), the source coating unit control unit (56) first measures the discharge amount of the food sauce composition (S) measured by the discharge amount measuring unit (23) when the pump (22) is driven at a predetermined driving amount (e.g., low speed). Next, the source coating unit control unit (56) calculates the relationship between the driving amount of the pump (22) and the discharge amount of the food sauce composition (S). The source coating unit control unit (56) controls the pump (22) based on the calculated relationship of the pump (22) so as to realize the discharge amount of the food sauce composition (S) determined by the source supply amount determining unit (55).

[0098] The scraper unit control unit (57) controls the scraper deployment device (49) to change the scraper body (31) from the storage configuration (C1) to the deployment configuration (C2) while the tumbler body (10) is stopped at the scraping start rotation position (R0) and the scraper body (31) is positioned at the scraping start position (Q1).

[0099] After the scraper body (31) is converted into the deployment configuration (C2), the food (F) is supplied to the tumbler body (10), the tumbler body (10) is rotated at a predetermined rotation speed, and the food source composition (S) is coated on the food (F) by the source coating unit (20) through cooperation between the food supply control unit (53), the tumbler rotation control unit (54), and the source coating unit control unit (56).

[0100] In addition, in conjunction with the coating of the food source composition (S) on the food (F), the scraper main body (31) is returned to the X2 side. When the scraper unit control unit (57) detects that the scraper main body (31) has reached the scraping end position (Q2) by the first sensor (16), it controls the scraper translation device (44) to move the moving body (46) from the first position (PS1) to the second position (PS2). As a result, the scraper main body (31) is moved from the scraping end position (Q2) to the scraping start position (Q1).

[0101] Furthermore, when the scraper unit control unit (57) determines that the scraper main body (31) has reached the scraping start position (Q1), it stops the tumbler main body (10) at the scraping start rotation position (R0) via the tumbler rotation control unit (54). Here, the arrival of the scraper main body (31) at the scraping start position (Q1) may be detected using a sensor, or may be determined based on the passage of a predetermined time after the scraper translation device (44) is operated to move the moving body (46) from the first position (PS1) to the second position (PS2).

[0102] Next, the operation of the source coating system (1) will be described with reference to the flowcharts of FIGS. 7 and 8.

[0103] First, referring to Fig. 7, the overall operation of the source coating system (1) will be described. First, the food supply control unit (53) acquires the weight of the food (F) continuously measured by the weight scale (4) (step S1).

[0104] Next, the source supply amount determination unit (55) calculates the relationship between the driving amount or discharge amount of the pump (22) and the weight of the food source composition (S) discharged by the pump (22) (step S2).

[0105] Next, the source supply amount determination unit (55) determines the amount of food source composition (S) to be discharged by the pump (22) based on the weight of the food (F) supplied to the tumbler body, with reference to a predetermined recipe read from the memory unit (51) (step S3).

[0106] Next, by the cooperation of the food supply control unit (53), the tumbler rotation control unit (54), and the source coating unit control unit (56), the food (F) is supplied to the tumbler body (10) by the food loading device (2), the tumbler body (10) is rotated at a predetermined rotation speed by the tumbler rotator (8), and the food (F) is coated with the food sauce composition (S) by the source coating unit (20) (steps S4 and S5).

[0107] Here, in step S5, a portion of the food (F) and the food sauce composition (S) are mixed and hardened inside the tumbler body (10) to form sludge, which may adhere to the inner surface (11a) of the tumbler. Therefore, in the present embodiment, in order to remove the sludge from the inner surface (11a) of the tumbler, scraping of the inner surface (11a) of the tumbler by the scraper unit (30) is performed in parallel with the coating of the food sauce composition (S). Hereinafter, the operation of the scraper unit (30) will be described with reference to FIG. 8.

[0108] Referring also to Fig. 9a, scraping of the inner surface (11a) of the tumbler by the scraper unit (30) is initiated from a state in which the scraper body (31) is positioned at the scraping start position (Q1) in the deployed configuration (C2) (step S11). At this time, the tumbler body (10) is stopped at the scraping start rotation position (R0).

[0109] Next, referring to FIG. 9b, the tumbler rotation control unit (54) rotates the tumbler body (10), and accordingly, the scraper body (31) is pushed by the screw wall (12) and moves toward the X2 side (step S12). At this time, the scraper body (31) has a deployment configuration (C2), and the scraping unit (33e) spirally scrapes the inner surface (11a) of the tumbler to scrape off sludge that may adhere to the inner surface (11a) of the tumbler.

[0110] Next, referring to FIG. 9c, as the scraper body (31) approaches the scraping end position (Q2), it is converted into the containment configuration (C1) by the scraper containment guide (47) and then reaches the scraping end position (Q2) (step S13).

[0111] Next, the first sensor (16) detects that the scraper body (31) has reached the scraping end position (Q2) (step S14). The detection result by the first sensor (16) is input to the control device (50).

[0112] Next, referring to FIGS. 9d and 9e together, the scraper unit control unit (57) controls the scraper translation device (44) to move the moving body (46) from the first position (PS1) to the second position (PS2). As a result, the scraper main body (31) is pushed by the moving body (46) and moves toward the X1 side (step S15).

[0113] Next, referring to FIG. 9f together, after the scraper body (31) reaches the scraping start position (Q1), the tumbler rotation control unit (54) stops the tumbler body (10) at the scraping start rotation position (R0) based on the detection result of the detection unit (10a) by the second sensor (17) (step S16).

[0114] Finally, referring to FIG. 4 together, the scraper unit control unit (57) controls the scraper deployment device (49) to protrude the load (49a) toward the Y2 side, thereby displacing the scraper (33) toward the Y2 side, thereby converting the scraper body (31) into the deployment configuration (C2) (step S17).

[0115] Afterwards, steps S11 to S17 are repeated, so that spiral scraping of the inner surface (11a) of the tumbler by the scraper body (31) is repeatedly performed.

[0116] According to the tumbler device (6) and source coating system (1) related to the present embodiment, the following effects are achieved.

[0117] (1) The tumbler device (6) is a cylindrical body with a center line (O1) extending laterally, and has a tumbler inlet (11b) opening on the X1 side in the X direction parallel to the center line (O1), a tumbler outlet (11c) opening on the X2 side in the X direction, a tumbler inner surface (11a) connecting the tumbler inlet (11b) and the tumbler outlet (11c), and a screw wall (12) protruding from the tumbler inner surface (11a) toward the inner diameter and extending in a spiral shape from the tumbler inlet (11b) along the tumbler inner surface (11a) toward the tumbler outlet (11c), and a tumbler rotator (8) that rotates the tumbler body (10) about the center line (O1), and a tip end that is spirally shaped. It has a scraper body (31) having a scraper (33) that contacts the inner surface of the tumbler (11a) at a position adjacent to each other in the X2 direction with respect to at least some of the screw walls (12) of the extending screw walls (12).

[0118] When the tumbler body (10) is driven to rotate, food (F) supplied from the tumbler inlet (11b) is supported on the inner surface (11a) of the tumbler and returned to the tumbler outlet (11c) by the screw wall (12). Here, sludge caused by the food (F), especially sludge caused by the food (F) and the food sauce composition (S) when the food sauce composition (S) is attached to the food (F) within the tumbler body (10), is likely to adhere to the inner surface (11a) of the tumbler.

[0119] The tumbler device (6) related to the present embodiment is provided with a scraper (33), and the scraper (33) is in contact with the tumbler inner circumference (11a) at a position adjacent to at least a portion of the screw wall (12) extending in a spiral shape in the X2 direction. As a result, the scraper (33) spirally scrapes the tumbler inner circumference (11a) along the screw wall (12) that rotates in accordance with the rotation of the tumbler body (10). Therefore, since the adhesion of sludge to the tumbler inner circumference (11a) is suppressed, the frequency of cleaning, such as manually removing sludge from the tumbler inner circumference (11a), can be reduced. Therefore, since the sludge can be effectively removed from the tumbler inner circumference (11a), the operating rate of the tumbler device (6) is improved.

[0120] (2) The scraper (33) may have its tip in contact with the screw wall (12) from the X2 side.

[0121] As a result, when the tumbler body (10) rotates, the scraper (33) can be pushed and moved toward the X2 side by the rotating screw wall (12). Therefore, a separate driving means for moving the scraper (33) toward the X2 side is not required. Therefore, a tumbler device (6) equipped with a scraper (33) that scrapes in a spiral shape can be realized at low cost with a simple configuration while suppressing an increase in the number of parts.

[0122] (3) The scraper body (31) is further provided with a scraper base (32) that rotatably supports the base of the scraper (33) and is movable in the X direction, and the scraper body (31) may be converted into a deployment configuration (C2) in which the scraping portion (33e) contacts the inner surface (11a) of the tumbler by rotating the scraper (33) relative to the scraper base (32), and a containment configuration (C1) in which the scraping portion (33e) is located on the inner diameter side relative to the screw wall (12).

[0123] When the scraper body (31) reaches the scraping end position (Q2), it is necessary to return the scraper body (31) to the scraping start position (Q1). At this time, when the scraper body (31) is in the deployed configuration (C2), it is necessary to move the scraper (33) in a spiral shape along the inner surface (11a) of the tumbler toward the scraping start position (Q1), so the movement time of the scraper body (31) becomes long.

[0124] In this regard, according to the present configuration, by converting the scraper body (31) into a containment configuration (C1), it is possible to move it linearly in the X direction while preventing interference between the scraper (33) and the screw wall (12), so that the scraper body (31) can be moved to the scraping start position (Q1) in a short time. Accordingly, the time required to return the scraper body (31) to the scraping start position (Q1) is shortened, so that the operating rate of the tumbler device (6) is improved.

[0125] (4) It is also possible to additionally provide a scraper translation device (44) that moves the scraper body (31) to the scraping start position (Q1).

[0126] As a result, the scraper body (31) can be moved to the scraping start position (Q1) by the scraper translation device (44) in a state where it is converted to a containment configuration (C1).

[0127] (5) In the unfolded configuration (C2), the scraper body (31) may have a rotational moment due to its own weight centered on the base portion of the scraper (33) applied in a direction toward the inner surface of the tumbler (11a), and in the contained configuration (C1), the rotational moment may be applied to the scraper (33) in a direction away from the inner surface of the tumbler (11a).

[0128] As a result, the scraper body (31) can be maintained by the rotational moment due to its own weight in the deployment configuration (C2) and the containment configuration (C1) without requiring a biasing means.

[0129] (6) When the scraper body (31) reaches the scraping end position (Q2), it may be converted into a storage configuration (C1).

[0130] As a result, when the scraper body (31) reaches the scraping end position (Q2), i.e., when scraping by the scraper (33) is finished, the scraper body (31) can be converted into a storage configuration (C1) to prepare for movement to the scraping start position (Q1).

[0131] (7) When the scraper body (31) reaches the scraping end position, a scraper containment guide (47) may be additionally provided to generate a rotational moment in the direction of separation from the tumbler inner surface (11a) in the scraper (33).

[0132] As a result, by utilizing the movement when the scraper body (31) reaches the scraping end position (Q2), the scraper (33) can be rotated by the scraper containment guide (47) to convert the scraper body (31) into the containment configuration (C1). Therefore, an actuator for converting the scraper body (31) into the containment configuration (C1) is not required.

[0133] (8) The screw wall (12) may have a radial height that contacts the scraper (33) at least until a rotational moment due to the weight of the scraper (33) in the direction away from the tumbler inner surface (11a) is generated when the scraper body (31) is converted toward the containment structure (C1) by the scraper containment guide (47).

[0134] As a result, the movement of the scraper body (31) by the screw wall (12) can be continued until a rotational moment is generated in the direction of separation from the tumbler inner surface (11a) of the scraper (33), so that the scraper body (31) can be reliably converted into the containment configuration (C1).

[0135] (9) When the scraper body (31) reaches the scraping start position (Q1), it may be converted to the deployment configuration (C2).

[0136] As a result, when the scraper body (31) reaches the scraping start position (Q1), the scraper body (31) can be converted to the deployment configuration (C2), and then scraping can be started.

[0137] (10) When the scraper body (31) reaches the scraping start position (Q1), a scraper deployment device (49) that rotates the scraper (33) to transform the scraper body (31) into the deployment configuration (C2) may be additionally provided.

[0138] As a result, the scraper body (31) can be converted from the containment configuration (C1) to the deployment configuration (C2) by the scraper deployment device (49).

[0139] (11) A second sensor (17) is additionally provided to detect that the rotational position of the tumbler body (10) is the scraping start rotational position (R0), and here, interference in the radial direction of the screw wall (12) with respect to the scraper (33) that is converted to the deployment configuration (C2) at the scraping start rotational position (R0) is avoided, and the scraper deployment device (49) may convert the scraper body (31) from the storage configuration (C1) to the deployment configuration (C2) after the tumbler rotator (8) stops the tumbler body (10) at the scraping start rotational position (R0).

[0140] As a result, after stopping the tumbler body (10) at the scraping start rotation position (R0), interference between the scraper (33) and the screw wall (12) is prevented by converting the scraper body (31) to the unfolded configuration (C2).

[0141] (12) The source coating system (1) is a tumbler device (6) related to the above configurations (1) to (11), and further includes a source coating unit (20), and a weight scale (4) for measuring the weight of food (F) supplied to the tumbler body (10), and the source coating unit (20) includes a spraying unit (24) for spraying a food source composition (S) to the food (F) supplied to the tumbler body (10), a pump (22) for discharging the food source composition (S) and supplying it to the spraying unit (24), a discharge amount measuring unit (23) for measuring the weight of the food source composition (S) discharged from the pump (22), and a recipe in which the relationship between the weight of the food source composition (S) and the weight of the food (F) stored in advance in the memory unit (51) is stipulated, and the weight of the food (F) is measured by referring to the recipe. It is provided with a control device (50) that controls the operation of the pump (22) to adjust the supply amount of the food source composition (S) based on the basis.

[0142] As a result, the food (F) supplied to the tumbler body (10) is sprayed with a food sauce composition (S) of an appropriate weight referring to the recipe according to the weight, so that the amount of the food sauce composition (S) supplied to the food (F) is appropriately set. Accordingly, the texture and taste of the food (F) can be stabilized.

[0143] (13) The tumbler body (10) may have a rotation speed of 3 rpm or more and 8 rpm or less, and an inclination angle (θ) of the center line (O1) with respect to the horizontal direction of 4° or more and 6° or less.

[0144] As a result, the phenomenon of food (F) being stuck to each other in the tumbler body (10) is minimized, and also, it is easy to uniformly coat the food (F) with the food source composition (S).

[0145] (14) When spraying the food source composition (S), the spray unit (24) may inject compressed air.

[0146] As a result, the food source composition (S) is sprayed finely and uniformly, making it easy to obtain a dish coated with the food source composition (S) to the required level.

[0147] (15) It is also possible to additionally have a heating means (25) for maintaining the food source composition (S) at a predetermined temperature.

[0148] As a result, the food source composition (S) can be maintained at a viscosity suitable for spraying, making it easy to uniformly coat the food (F) with the food source composition (S).

[0149] [Second Embodiment]

[0150] Referring to FIGS. 10 to 13, a source coating system according to a second embodiment will be described. The source coating system according to the second embodiment has a different tumbler device (60) than the source coating system (1) according to the first embodiment. As shown in FIG. 10, the tumbler device (60) differs from the tumbler device (6) according to the first embodiment in that it has a scraper deployment guide (61) instead of a scraper deployment device (49).

[0151] That is, in the source coating system related to the second embodiment, the coating of the food source composition (S) onto the food (F) is the same as in the first embodiment, and only the operation of the scraper unit (30) is different. More specifically, in the tumbler device (60), only the configuration for converting the scraper body (31) from the containment configuration (C1) to the deployment configuration (C2) is different from the tumbler device (6) related to the first embodiment. In the following description, the same reference numerals are used for the configurations common to the source coating system (1) and the tumbler device (6) related to the first embodiment, and the description thereof is omitted.

[0152] The scraper deployment guide (61) is fixed to the tumbler frame (7) via a bracket (not shown). The scraper storage guide (47) has a position in the X direction corresponding to the scraper main body (31) located at the scraping start position (Q1). The scraper deployment guide (61) is installed at a position where the end on the X2 side contacts the storage roller (37) of the scraper main body (31) which is the storage configuration (C1) from the Y1 side. The scraper deployment guide (61) extends in a direction inclined toward the Y2 side toward the X1 side.

[0153] Fig. 11 is a rear view of the scraper unit (30) as seen from the X2 side, similar to Fig. 4. Fig. 11 shows, in a solid line, a case where the scraper main body (31) is in a containment configuration (C1). Referring also to Fig. 11, the scraper deployment guide (61) is set to displace the containment roller (37) toward the Y2 side until a rotational moment due to the scraper's own weight is generated about the rotational axis (O2) toward the tumbler inner surface (11a) of the scraper (33), i.e., until the neutral configuration (C0) is exceeded. Specifically, the scraper deployment guide (61) is set to have a displacement amount toward the Y2 side so that the scraper (33) rotates beyond the neutral configuration (C0) from the containment configuration (C1) while the scraper main body (31) is being pushed toward the X1 side by the scraper translation device (44).

[0154] Next, the operation of the scraper unit (30) in the tumbler device (60) will be described with reference to the flowchart of Fig. 12.

[0155] As for steps S21 to S24, they are performed in the same manner as steps S1 to S4 in the first embodiment, as shown in FIGS. 13a to 13c.

[0156] Next, referring to FIG. 13d, the tumbler rotation control unit stops the tumbler body (10) at the scraping start rotation position (R0) based on the detection result of the detection part (10a) by the second sensor (17) (step S25).

[0157] Next, referring to FIG. 13e, the scraper unit control unit (57) controls the scraper translation device (44) to move the moving body (46) from the first position (PS1) to the second position (PS2). As a result, the scraper main body (31) is pushed by the moving body (46) and moves toward the X1 side (step S26).

[0158] Finally, as the scraper body (31) approaches the scraping start position (Q1), it is converted into the expanded configuration (C2) by the scraper expansion guide (61), as shown in Fig. 11, and then reaches the scraping start position (Q1) (step S27). Here, when the scraper body (31) is positioned at the scraping start position (Q1), the tumbler body (10) is stopped at the scraping start rotation position (R0), so that interference between the scraper (33) and the screw wall (12) when the scraper body (31) is converted from the containment configuration (C1) to the expanded configuration (C2) is avoided.

[0159] Afterwards, steps S21 to S27 are repeated, so that spiral scraping of the inner surface (11a) of the tumbler by the scraper body (31) is repeatedly performed.

[0160] That is, the tumbler device (6) related to the present embodiment additionally includes a scraper deployment guide (61) that rotates the scraper (33) to convert the scraper body (31) into a deployment configuration (C2) when the scraper body (31) reaches the scraping start position (Q1).

[0161] As a result, by utilizing the movement when the scraper body (31) reaches the scraping start position (Q1), the scraper (33) can be rotated by the scraper deployment guide (61) to convert the scraper body (31) into the deployment configuration (C2). Therefore, a separate actuator (scraper deployment device (49)) for converting the scraper body (31) into the deployment configuration (C2) is not required.

[0162] Meanwhile, the present disclosure is not limited to the configuration described in the above embodiment, and various changes are possible.

[0163] Fig. 14 is a rear view of a scraper unit (30) similar to Fig. 5, viewed from the X2 side, showing a scraper (71) related to a modified example. The scraper (71) is different from the scraper (33) related to each of the above embodiments in that the scraping portion (33e) is installed so as to be rotatable about the scraper shaft portion (33c).

[0164] Specifically, the scraper (71) additionally has a coil spring (72) that biases the scraping portion (33e) clockwise around the scraper shaft portion (33c), and a stopper (73) that is mounted across the tips of a pair of arm second portions (33b) and determines the rotational position of the scraping portion (33e).

[0165] According to the scraper (71) related to the modified example, the scraping section (33e) is maintained in a posture that is extended parallel to the second arm section (33b) by being positioned by the stopper (73) to scrape the inner surface (11a) of the tumbler, and when the baffle (13) passes or when the resistance due to sludge becomes excessive, it rotates counterclockwise against the biasing by the coil spring (72), thereby avoiding excessive force from being applied to the scraper (33).

[0166] Figures 15 and 16 illustrate a scraper (81) related to another modified example. Figure 15 is a front view of the scraper unit (30) showing the periphery of the scraper (81), and Figure 16 is a front view of the scraper unit (30) showing the periphery of the scraper (81). As shown in Figure 15, the scraper (81) differs from the scraper (33) related to each of the above embodiments in that it has another side roller (82) on the side on the X1 side.

[0167] As shown in Fig. 16, the side roller (82) has a rotation axis (O4) extending in the Y direction and is in contact with the wall surface on the X2 side of the screw wall (12) when the scraper body (31) is in the deployed configuration (C2). That is, when the tumbler body (10) rotates clockwise in Fig. 16, the side roller (82) rolls on the wall surface on the X2 side of the screw wall (12) with the rotation axis (O4) as the center.

[0168] That is, the scraper (81) related to another modified example has a side roller (82) on a portion of the screw wall (12) facing the X1 side in the deployment configuration (C2), and the side roller (82) rolls on the wall surface on the X2 side of the screw wall (12) that rotates in accordance with the rotation of the tumbler body (10). As a result, the sliding resistance between the scraper (81) and the rotating screw wall (12) is reduced, so that the scraper (81) can be smoothly moved to the X2 side by the rotating screw wall (12).

[0169] Here, the side roller (82) may be installed on the side of the X2 side of the scraper (81).

[0170] The present invention may include a method for producing food using a tumbler device (6) according to the first embodiment or a tumbler device (60) according to the second embodiment. For example, the method for producing food may be a method using a tumbler device (6, 60) each having a scraper (33), a scraper (71), and a scraper (81).

[0171] In addition, the present invention may include a method for producing a food product using the source coating system (1) according to the first embodiment or the source coating system (1) according to the second embodiment. For example, the method for producing a food product may be a method using a source coating system (1) having a scraper (33), a scraper (71), and a scraper (81), respectively.
