Description

[Technical Field]

[0001] The present invention relates to a liquid application device that applies a liquid such as oil or fat to the surface of an object to be applied, such as a baking sheet used when baking various types of bread and food ingredients (hereinafter, breads such as white bread and sweet buns, confectioneries such as sweets and cakes, and food ingredients such as pâté are collectively referred to as bread). [Background technology]

[0002] The present applicant proposed a liquid applicator for applying a liquid such as oil or fat to the surface of a baking tray for baking bread in Patent Document 1. The liquid applicator is composed of a liquid-retaining rotor provided in a case and driven to rotate by a drive means, an opening provided in the case at a location corresponding to the outer periphery of the liquid-retaining rotor and enabling the liquid supplied by the centrifugal force accompanying the rotation of the liquid-retaining rotor to be discharged outside the case, an on-off valve for opening and closing the opening, an operating member for operating to open and close the on-off valve, and recovery means provided in the case around the opening periphery for recovering the liquid adhering to the opening periphery, and the liquid adhering to the rotating liquid-retaining rotor is applied to the surface of the baking tray being transported below the opening through the opening opened by the centrifugal force.

[0003] However, in the above-mentioned liquid application device, for example, if the conveying direction of the top plate is the column direction and the direction perpendicular to the conveying direction is the row direction, by opening and closing the on-off valve, the liquid can be applied intermittently at appropriate intervals in the column direction, but it is not possible to apply the liquid intermittently at appropriate intervals in the row direction.

[0004] For example, in the case of a baking tray for baking sweet buns, the dough or other baked items are placed in a matrix at appropriate intervals in the row and column directions and baked. However, before the bread is baked, it is necessary to apply oil to the surface of the baking tray. When applying oil to the surface of the baking tray using the liquid application device, the oil is applied to at least the entire row direction, including areas other than where the dough or other items are placed. This poses the problem of increased oil consumption because the oil is also applied to areas where the dough or other items are not placed.

[0005] Furthermore, in the liquid application device, as described above, the liquid is applied to at least the entire row direction, so when cleaning the baking tray after baking bread, the oil and grease applied to areas where no bread dough or the like is placed must also be cleaned and removed, which results in a problem of increased detergent consumption and makes the cleaning process time-consuming and labor-intensive. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 4947765 Summary of the Invention [Problem to be solved by the invention]

[0007] The problem to be solved is that the liquid such as oil or fat is applied to areas of the object other than the liquid application area where the baked item such as bread dough is placed, resulting in a large amount of liquid consumption.

[0008] Furthermore, since the liquid is applied to the entire surface of the object to be coated, at least in the row direction, when cleaning the object to be coated after baking bread, the liquid applied to areas where no bread dough or the like is placed must also be washed and removed, which results in a large amount of detergent being consumed and makes the cleaning process more time-consuming and labor-intensive. [Means for solving the problem]

[0009] The present invention relates to a liquid application device that applies liquid by scattering, by centrifugal force caused by rotation, liquid adhering to a liquid holding rotor that is provided within a main body case and rotated by a drive member, onto a workpiece that is conveyed through a discharge opening provided in the main body case. The liquid holding rotor has a rotation shaft having an axis in a direction perpendicular to the conveyance direction, on which a number of application rotary plates are provided at predetermined intervals in the axial direction, a number of partition plates that are disposed below the liquid holding rotor and extend in the conveyance direction and are arranged in parallel in the direction perpendicular to the conveyance direction, a liquid trough provided with a number of liquid reservoirs partitioned corresponding to the application rotary plates, an opening / closing member that selectively opens and closes the discharge opening, an opening / closing operating member that operates the opening / closing member to open and close, and a number of openings that open and close openings provided between the partition plates located on the opposite side to the opening / closing member while sliding against the partition plates located on both sides. The apparatus comprises on-off valves, on-off valve operating members which selectively open and close the on-off valves, and a liquid tank provided on the opposite side of the liquid trough from the on-off member and which stores the liquid to be applied to the object to be coated. A plurality of liquid application areas are set on the object to be coated at predetermined intervals in the conveying direction and in the direction perpendicular to the conveying direction, and openings are closed by on-off valves which operate in accordance with the width and number of the liquid application areas. Liquid is supplied from the liquid tank to the liquid pools between the corresponding partition plates and adheres to the rotating coating rotary plate so that it can be scattered. As the object to be coated is conveyed, the on-off member is opened in accordance with the width of the liquid application area in the conveying direction, and as the coating rotary plate to which the liquid has adhered rotates, the liquid is scattered through the discharge opening, thereby applying the liquid to the plurality of liquid application areas at predetermined intervals in the conveying direction and in the direction perpendicular to the conveying direction. [Effects of the Invention]

[0010] The present invention provides a liquid application device that can reduce the amount of liquid consumed by applying liquid only to the liquid application area of ​​the application target where the object to be baked is placed.

[0011] To provide a liquid application device which, in the cleaning work of a coated object after baking bread, can reduce the consumption of detergent by only removing the liquid applied to a liquid application area where the baked object is placed, and can improve the cleaning efficiency by reducing the labor and time required for the cleaning work.

[0013] In the best mode, a plurality of liquid application areas are set on the object to be coated at predetermined intervals in the transport direction and in the direction perpendicular to the transport direction, the openings are closed by opening / closing valves that operate in accordance with the width and number of the liquid application areas, liquid is supplied from a liquid tank to a liquid pool between the corresponding partition plates and adheres to the rotating coating rotary plate so that it can be scattered, and as the object to be coated is transported, an opening / closing member is opened in accordance with the width of the liquid application area in the transport direction, and the liquid is scattered through the discharge opening as the coating rotary plate to which the liquid has adhered rotates, thereby applying liquid to the plurality of liquid application areas at predetermined intervals in the transport direction and in the direction perpendicular to the transport direction. [Example]

[0014] Hereinafter, a liquid application device according to the present invention will be described with reference to the drawings showing an embodiment in which the liquid application device is implemented as a top plate grease application device for applying grease to a top plate as an object to be applied. As shown in Figures 1 to 7, a baking sheet conveying device 5 that is driven to convey in the direction of the arrow shown is disposed below the main body case 3 of the baking sheet oiling device 1 as a liquid application device, and the baking sheet conveying device 5 conveys baking sheets 7 as coated objects for baking bread that are placed on the upstream side in the conveying direction at a constant conveying speed.

[0015] A rotating shaft 9 having an axis perpendicular to the conveying direction is supported at the top of the main body case 3, and a number of coating rotating plates 11a, which are disk-shaped, polygonal (triangular, square, pentagonal, etc.) when viewed from the side, or gear-shaped with a number of protrusions on the outer periphery, are arranged on the rotating shaft 9 at intervals between the partition plates 35 described below in the axial direction, and these rotating shafts 9 and coating rotating plates 11a form an oil and grease retaining rotating body 11 as a liquid retaining rotating body.

[0016] In addition, the grease holding rotor 11 is connected to an electric motor 13 provided outside the main body case 3 via a reduction mechanism (not shown) if necessary, and rotates in the clockwise direction as shown in the figure when the electric motor 13 is driven.

[0017] A grease trough 15 is disposed in the main body case 3 below the grease-holding rotor 11, and serves as a liquid trough having a width in the direction perpendicular to the conveyance that corresponds at least to the top plate 7, an appropriate width in the conveyance direction, and an appropriate depth. An inclined portion 15a that slopes upward along the rotational path of the grease-holding rotor 11 is provided on the upstream side of the grease trough 15 in the conveyance direction, and a discharge opening 19 for the scattered grease is formed between the upstream end of the inclined portion 15a in the conveyance direction and the downstream end of an inclined plate 17 provided on the main body case 3 in the conveyance direction.

[0018] The grease trough 15 is tilted so that its upstream side in the conveying direction is slightly higher than its downstream side in the conveying direction, and is configured so that the grease in the grease reservoir 35a between the partition plates 35 described later flows toward the downstream side in the conveying direction.

[0019] An opening / closing shaft 25 connected to an opening / closing actuating member 23 such as an air cylinder or an electromagnetic solenoid is journalled on the main body case 3 corresponding to the discharge opening 19, and a shutter 27 serving as an opening / closing member made of a synthetic resin such as silicone rubber, fluorinated resin or polyacetal resin and having an oblong or plate-shaped side surface is provided on the opening / closing shaft 25 according to the opening width of the discharge opening 19. The shutter 27 opens and closes the discharge opening 19 in accordance with the operation of the opening / closing actuating member 23.

[0020] A grease scattering prevention plate 29 with a semicircular side is disposed on the main body case 3 corresponding to the upper outer periphery of the grease holding rotor 11. In addition, grease collection troughs 31 extending in the direction perpendicular to the conveyance direction are attached to the main body case 3 corresponding to the upstream and downstream sides in the conveyance direction below the discharge opening 19, and are capable of receiving and collecting excess grease discharged from the discharge opening 19.

[0021] Within the grease trough 15, a number of partition walls 35 extending in the conveying direction are provided at intervals between the coating rotary plates 11a in the direction perpendicular to the conveying direction, and grease reservoirs 35a are formed between these partition walls. A portion of the outer periphery of the corresponding coating rotary plate 11a is immersed in the grease reservoir 35a between the partition walls 35, and grease is deposited therein. In addition, the partition walls 35 located at the downstream end in the conveying direction are open.

[0022] A grease tank 37 is disposed downstream of the grease trough 15 in the conveying direction as a liquid tank for supplying grease into the grease trough 15. When a selected on-off valve 39 (described later) is lowered, the grease tank 37 passes over the on-off valve 39 and supplies grease into the grease reservoir 35a between the partition plates 35.

[0023] An opening 15b is provided in the bottom surface of the grease trough 15 corresponding to the space between the partition plates 35 on the downstream end side in the conveying direction, and an on-off valve 39 is provided in each opening 15b so as to abut against the partition plates 35 located on both sides and be airtight (in this invention, an airtight state means a state in which abutment against the partition plates 35 prevents the grease in the grease tank 37 from flowing into the grease reservoir 35a between the partition plates 35). The on-off valve 39 is, for example, cylindrical or rectangular prism-shaped, and on its upstream side in the conveying direction, a drain groove 39a is formed extending downward from the middle in the vertical direction so as to be able to communicate with the outside.

[0024] In addition, a valve rod 43 is provided at the upper end of each on-off valve 39, and is supported so as to be movable in the vertical direction relative to a support plate 41 provided on the main body case 3. Each valve rod 43 is biased upward along its axis by an elastic member 45, such as a compression spring or rubber tamper, provided between the support plate 41 and the upper axial portion of the valve rod 43.

[0025] When the valve rod 43 of each opening / closing valve 39 moves upward along its axis, the upper part of the corresponding drain groove 39a is positioned above the bottom surface of the grease trough 15 between the partition plates 35, and part of the opening 15b is connected to the outside, allowing the grease remaining in the grease reservoir 35a to be discharged into a grease pan 47 located below the grease trough 15.

[0026] Conversely, when the valve rod 43 of each opening / closing valve 39 moves axially downward, the corresponding drain groove 39a is positioned below the bottom surface of the grease trough 15, closing the opening 15b, thereby preventing the grease accumulated in the grease reservoir 35a from being discharged into the grease pan 47, and the downward movement of each opening / closing valve 39 causes the grease accumulated in the grease tank 37 to flow over the top of the opening / closing valve and into the spaces between the partition plates 35.

[0027] The grease collected in the grease collection trough 31 and the grease pan 47 is returned to the grease tank 37 as a connected pump (not shown) is driven, and is reused. The grease tank 37 is also provided with a float-type, ultrasonic-type or other liquid level detector (not shown), which outputs a detection signal when the liquid level drops due to consumption of the grease stored in the grease tank 37, and supplies grease from a grease tank (not shown) based on the detection signal, while stopping the supply of grease from the grease tank (not shown) when the detector transitions to a non-detection state, thereby maintaining a constant amount of grease stored in the grease tank 37.

[0028] A valve operating member 49 is provided in the main body case 3 above each valve rod 43. The valve operating member 49 can be raised and lowered in the vertical direction by an elevating member 49a, such as a cylinder or an electromagnetic solenoid, provided in the main body case 3 opposite to each valve rod 43, and is rotatably connected by an electric motor 49b, such as a numerically controllable pulse motor, connected thereto, and is configured as a pressing rotor 49e in which a plurality of pressing rod groups 49d, each group consisting of pressing rods 49c the number of which corresponds to the row width of each grease application area a set in the row direction on the top plate 7, are provided at predetermined angles around the axis of the outer circumferential surface.

[0029] For example, on the outer periphery at the 0 degree position of the pressing rotor 49e, if two grease application areas a are set in the row direction, two sets of pressing rod groups 49d each consisting of a number of pressing rods 49c corresponding to the row width of each grease application area are provided along the axial direction; on the outer periphery at the 90 degree position, if three grease application areas a are set in the row direction, three sets of pressing rod groups 49d each consisting of a number of pressing rods 49c corresponding to the row width of each grease application area are provided along the axial direction; on the outer periphery at the 180 degree position, if four grease application areas a are set in the row direction, four sets of pressing rod groups 49d each consisting of a number of pressing rods 49c corresponding to the row width of each grease application area are provided along the axial direction; and on the outer periphery at the 270 degree position, if five grease application areas a are set in the row direction, five sets of pressing rod groups 49d each consisting of a number of pressing rods 49c corresponding to the row width of each grease application area are provided along the axial direction.

[0030] In addition to the above configuration, the valve operating member 49 may be any of the following: a linear operating member (not shown) such as an electromagnetic solenoid or air cylinder arranged corresponding to the upper part of each valve rod 43; a cam member (not shown) provided corresponding to each valve rod 43 on a cam shaft rotatably supported by an electric motor connected above each valve rod 43, and having multiple sets of cam plates on its outer periphery having cam surfaces that slide against the valve rod 43 corresponding to the multiple oil application areas a in the direction perpendicular to the conveying direction on the top plate 7; or a structure in which multiple sets of bar materials (not shown) having lengths corresponding to the widths of each oil application area set in the row direction of the top plate 7 are attached at an appropriate angle to the outer periphery of the pressing rotor 49e.

[0031] For example, when three grease application areas a are set at appropriate intervals in the direction perpendicular to the conveying direction on the top plate 7, the valve operating member 49 drives the electric motor 49b to rotate the pressing rotor 49e, and brings the pressing rod group 49d corresponding to the grease application area a into opposition to the upper part of the corresponding valve rod 43. Then, the lifting member 49a is operated to lower the pressing rotor 49e, thereby lowering the valve rod 43 against the elastic force of the elastic member 45.

[0032] Next, an example will be explained in which, using the tabletop oil application device 1 configured as described above, three columns and four rows of oil application areas a are set on the tabletop 7 at predetermined intervals in the column and row directions, as shown in Figure 8, and oil is applied to each oil application area a.

[0033] The number of oil application areas in the column and row directions assumed on the top plate 7 can be arbitrarily set depending on the size of the baked bread and the unbaked bread dough to be placed on the top plate 7, and is of course not limited to the above example.

[0034] First, the electric motor 49b is driven to rotate the pressing rotor 49e, and the three pressing rod groups 49d arranged at predetermined intervals in the row direction are rotated so that they face downward and face the upper parts of the corresponding valve rods 43. Then, in this state, the lifting member 49a is operated to move the pressing rotor 49e downward, and each valve rod 43 abutting against each pressing rod group 49d is moved downward against the elastic force of the elastic member 45 (see FIG. 9).

[0035] In addition, if the number of grease application areas in the row direction is other than the above, the electric motor 49b is driven to rotate the pressing rotor 49e, and the pressing rod group 49d corresponding to the number of grease application areas is brought into opposition to the upper part of the corresponding valve rod 43.

[0036] When the opening / closing valve 39 is pushed down by each pressing rod group 49d and lowered so that its upper end is positioned slightly above the bottom surface of the grease trough 15 and the opening 15b is closed, the grease stored in the grease tank 37 flows over the upper end of the opening / closing valve 39 and into the grease reservoir 35a of each partition plate 35 corresponding to the lowered opening / closing valve 39 (see FIG. 10).

[0037] At this time, a part of the outer circumferential side of the application rotary plate 11a of the grease holding rotor 11 corresponding to the lowered on-off valve 39 is immersed in and adheres to the grease that has flowed into the grease reservoir 35a.

[0038] On the other hand, the on-off valve 39 located between the groups of pressure rods 49d is kept in an uplifted state by the elastic force of the elastic member 45, preventing the inflow of grease from the grease tank 37, and the drain groove 39a keeps the opening 15b open, allowing the grease in the corresponding grease reservoir 35a to flow out (see FIG. 11).

[0039] In the above state, when the electric motor 13 is driven to rotate the grease-retaining rotor 11 in the clockwise direction as shown, as the application rotor plate 11a rotates, the outer end portion thereof is immersed in the grease accumulated between the partition plates 35 and adheres to the grease, and the centrifugal force causes the adhered grease to be scattered in an approximately tangential direction of the grease-retaining rotor 11.

[0040] In the above state, the discharge opening 19 is kept closed by the shutter 27, so that the scattering of grease is prevented from being released to the outside.

[0041] When the top plate 7, which is placed on the top plate transport device 5 and transported in the above state, passes a top plate detector (not shown) provided upstream in the transport direction of the top plate grease application device 1, a top plate detection signal is output. A predetermined time t0 after the output of the top plate detection signal is delayed, and the opening / closing operating member 23 is operated for a time t1 corresponding to the column width of the grease application area a, and the shutter 27 rotates open to open the discharge opening 19, and the scattered grease is applied from the discharge opening 19 to three grease application areas a spaced apart in the column direction in the first row of the top plate 7 (see FIG. 12).

[0042] Then, after the time t1 has elapsed, the opening / closing operating member 23 is returned to close the shutter 27, which rotates closed, to close the discharge opening 19, thereby interrupting the application in the column direction on the top plate 7.After that, after the time t2 has elapsed from the time t1, which corresponds to the spacing between the grease application areas a, the opening / closing operating member 23 is operated for the time t1, and the shutter 27 rotates open to open the discharge opening 19, and the grease released to the outside through the discharge opening 19 is applied in the column direction to the grease application areas a in the second row, which are set at a predetermined interval in the row direction.

[0043] The top plate 7 is transported by repeating the above operation, and after grease is applied to three columns and four rows of grease application areas a set at predetermined intervals in the column and row directions, the top plate 7 is transported out.

[0044] Furthermore, while the grease holding rotor 11 is rotating, there is a risk that grease may scatter and accumulate in the grease reservoir 35a between the partition plates 35 corresponding to the on-off valve 39 which is still moving upward. Even in this case, the grease scattered into the grease reservoir 35a between the partition plates 35 is collected in the grease pan 47 via the drain groove 39a of the on-off valve 39, preventing the grease from accumulating in the grease reservoir 35a and therefore preventing it from being applied to the top plate 7 in accordance with the grease application areas a set in the row direction.

[0045] The number and width of the oil application areas in the row direction on the top plate 7 are determined by the number of pressing rods 43 that make up the pressing rod group 49d that are lowered, and the number and width of the oil application areas in the column direction can be set arbitrarily by the opening time of the discharge opening 19 by the shutter 27.

[0046] When the grease scattered as the grease-holding rotor 11 rotates and passes through the discharge opening 19, some of the grease may adhere to the outer periphery of the discharge opening 19 and drip down. Even in this case, the grease that drips down can be collected and reused by the grease collection trough 31 disposed below the discharge opening 19.

[0047] In the above description, the shutter 27 is configured to open and close the discharge opening 19 as it rotates, but in the present invention, the plate-shaped shutter 27 can also be slid to open and close the discharge opening 19.

[0048] In this embodiment, the amount of grease consumed can be reduced by applying grease only to the grease application areas a in the column and row directions set on the baking tray 7 on which the bread dough is placed when baking bread.

[0049] Furthermore, when cleaning the baking tray after baking bread, it is only necessary to remove the grease adhering to the grease application area a, thereby reducing the effort required for cleaning and the amount of detergent consumed. [Explanation of symbols]
