Description

The present invention relates to a mechanism that rotates inside an apparatus using rotational force transmitted from outside the apparatus. As an application, it relates to food processing equipment that performs processing such as cleaning, heating processing, cooling processing, thawing processing, etc., and transportation of processing objects.

In producing various processed foods for use in the restaurant industry and preserved foods, ingredients are often processed in liquids, such as washing them in water or soaking them in seasoning solutions or chemical solutions. In order to perform processing in liquid, it is possible to generate a water flow inside the device and perform cleaning and processing using the water flow. Methods for generating water flow include methods such as jetting water with a pump or screw, or rotating a water wheel with stirring blades. However, in the case of spraying, the injection port is likely to become clogged.

On the other hand, a motor is required to rotate the water wheel. However, since various small objects derived from the food ingredients can become entangled or adhere to the liquid, placing the motor in the liquid requires an enormous amount of maintenance. On the other hand, if a motor is provided outside the device and a shaft is passed through the outer wall of the device to rotate the water wheel inside the device, maintaining watertightness at the portion that penetrates the outer wall becomes a problem.

In response to this, a food processing apparatus as described in Patent Document 1 has been proposed. In this food processing apparatus, a water stream is supplied to a water tank in which food is mainly dropped and processed by a rotating water wheel equipped with stirring blades along the axial direction. A passive disk with a permanent magnet attached to the surface facing the wall is attached to one end of the rotary water wheel in the axial direction. A slight gap is provided between the passive disk and the wall surface of the outer water tank, which is the outer wall of the device, and no holes are made in the wall surface of the outer water tank. In addition, a motor is attached to the outside of the outer aquarium that faces the passive disk across the outer wall of the outer aquarium, and the motor rotates the operating disk, which has a permanent magnet attached to the surface facing the wall. Attach to. This operating disk is also placed in a position facing the passive disk with a slight gap between it and the wall surface from the outside and with the outer wall in between. That is, although the operating disk and the passive disk are attracted to each other, they are mounted so that they can rotate freely on the spot without coming any closer to the other side on the other side of the wall. When the operating disk is rotated by the motor, the passive disk is rotated by the magnetic force between the permanent magnets, and as the passive disk rotates, the rotary water wheel itself rotates and a water flow can be generated. In particular, since the mechanical mechanism is simple, it is easy to clean, and since there is no need to make holes in the wall, it is easier to maintain watertightness.

WO2015/156388 publication

However, if the rotary water wheel is taken out for cleaning after processing the food, the rotary water wheel must be removed from the sliding bearing that fixes it. At that time, if the passive disk approaches the outer wall where the operating disk is located, the passive disk will be pulled by the magnetic force from the operating disk and adhere to the wall surface, making it difficult to remove it due to the force of the strong magnet. There is. It is not impossible to remove the rotating water wheel by weakening the magnetic force applied to the passive disk by changing the direction of the rotating water wheel, but the passive disk and rotating water wheel, which are made entirely of SUS, are so heavy that even adults have difficulty lifting them. be. For this reason, it is difficult for a weak adult to perform maintenance alone, and there is a need to improve maintainability.

Therefore, this invention is an apparatus for rotating a rotating body that is to be rotated by rotating a passive disk installed in a water tank using magnetic force from a working disk installed outside the device. The purpose is to avoid the situation where it becomes stuck due to magnetic force and to make maintenance easier.

This invention is
It has a passive disc with a permanent magnet,
The passive disk is one in which rotation is transmitted by magnetic force along with the rotation of a working disk equipped with permanent magnets that face each other without contacting each other,
a mounting shaft connected to the passive disk at one end and rotatable on the same rotation axis;
a first joint formed at the other end of the mounting shaft;
a second joint that is capable of transmitting rotation of the mounting shaft in combination with the first joint and is separable from the first joint;
The above problem has been solved by a rotation transmission device having a rotating body connected to the second joint and capable of being rotated.

A first joint part and a second joint part combine to transmit rotation between the passive disk and the rotating body, and the first joint part and the second joint part are separated during maintenance. let When separated, only the rotating body can be removed while leaving the passive disk side intact. If it is only on the rotating body side, even if the horizontal position is slightly shifted, it will not be pulled by the operating disk and can be removed without difficulty. Furthermore, since the passive disk itself, which has a permanent magnet large enough to transmit rotation, has a certain amount of mass, the rotating body separated from the passive disk is the rotating body of a conventional device that is integrated with the passive disk. It is lighter, easier to lift, easier to handle, and easier to clean.

As a specific embodiment,
The operating disk is attached to the outside of the outer wall of the device so as to face the outer wall so as not to contact it,
The passive disk, the mounting shaft, the first joint, the second joint, and the rotating body are arranged inside the outer wall,
A passive rotating section including the passive disc, the mounting shaft, and a bearing that rotatably holds the mounting shaft is installed inside the device, and the passive disc does not touch the outer wall but extends along the outer wall. arranged in a position facing the operating disk with the sandwich in between,
The rotating body is attached to a sliding bearing fixed to the inner bottom surface of the device and having an open top shape,
An embodiment may be mentioned in which the rotating body can be separated and removed from the passive rotating section. This rotation transmission mechanism using magnetic force has the advantage that rotational force can be supplied from outside the device without making a hole in the outer wall of the device. Therefore, it is possible to suitably use a configuration in which the operating disk is installed outside the device, and the passive disk, the mounting shaft, etc. are installed inside the device. Further, the rotating body is attached to a sliding bearing fixed to the inner bottom surface of the device, but since the upper part of this sliding bearing is open, the rotating body separated from the passive disk is not subjected to any particular lateral force. It can be removed from the device by simply lifting it upwards.

The rotation transmission device according to this invention includes:
The passive rotation part has a fixed base that supports the bearing from below, and a fixed branch extending from the fixed base in a horizontal direction along the outer wall,
It can be fixed by being attached to a fixed mounting part fixed to the inner bottom surface of the device,
The fixed attachment part has a notch through which the fixed branch moving up and down passes when attaching and removing the passive rotation part,
The position of the passive rotating part when the fixed branch passes through the notch is further away from the outer wall than the position in the operating state where the passive disc rotates as the operating disc rotates,
With the passive rotating section attached to the fixed mounting section, the passive rotating section can be slid toward the outer wall so as to be in the operating state, and the passive rotating section is slidable toward the outer wall. a slide fixing part that fixes the rotating part in the position in the operating state;
An embodiment may be adopted in which a pressing plate is provided closer to the outer wall than the notch and abuts above the fixed branch at the position in the operating state.
While the rotating body is removed for maintenance, the passive rotating section including the passive disk is also difficult to maintain if it remains fixed inside the device. Therefore, the passive rotating part is fixed and can be removed. When installing, if the passive disk is brought too close to the outer wall, the passive disk will be drawn to the outer wall, so it was adjusted so that the passive disk does not hit the outer wall by approaching the outer wall from the side farther from the outer wall. It is preferable to be able to fix it in the position in the above-mentioned operating state.

As an embodiment of this slide fixing part, for example, an end position adjustment screw is attached to the inside of the device and can adjust the position of the tip from the outer wall side to the opposite side, and the passive rotation An example of this method is to hold the device in the operating state by applying some parts of the device. Further, a disk position adjustment screw having a male threaded portion that is inserted into and meshes with the female threaded portion that penetrates in the axial direction of the passive rotating portion is attached, and a pressing portion provided at the tip of the disk position adjustment screw on the outer wall side. There is also a mode in which the disk is held in the operating state by applying it to the outer wall and adjusting the position of the disk position adjustment screw.

Furthermore, in addition to the above embodiments,
Above the pressing plate, an eaves portion is provided that extends in a direction away from the outer wall and covers at least a portion of the outer wall side above the cutout portion;
An embodiment may be adopted in which the lower side of the eaves part has an inclined part that is inclined in a direction that increases upward and moves away from the outer wall. In this embodiment, when the passive rotating part is removed, the stationary branch moves away from the outer wall along the inclined part, so that the passive disk is drawn to the outer wall and does not move when the passive rotating part is removed. You can prevent yourself from getting into a situation.

In this rotation transmission device, the device to be mounted stores a processing basket with an open top surface in a water tank with an open top surface, supports the processing cage within the water tank, and lifts the processing cage to the outside of the water tank. It can be suitably used in a food processing apparatus provided with a drive device that rotates the open surface of a lever processing basket so that it is tilted in one direction.
That is, it has an outer aquarium in contact with the aquarium, and the outer wall is an outer wall of the outer aquarium,
A partition wall that partitions the water tank and the outer water tank is provided with a water flow from the outer water tank at a position below the water level of the water tank during food processing and above half the depth of the deepest part of the water tank. A first water flow passage section is provided through which the water can pass.
The processing basket is provided with a second water flow passage port capable of introducing the water flow from the first water flow passage portion at a position facing the first water flow passage portion when stored in the water tank, and , water can freely flow in and out of this processing basket,
The rotation transmission device is provided in the outer water tank,
In the outer water tank, a rotary water wheel, which is the rotary body that generates the water flow, has its rotating shaft horizontally arranged along the partition wall, and the upward water flow generated by the rotary water wheel is directed to the first water tank. As an embodiment, a food processing apparatus may be employed in which a rectifying section for rectifying water flow to a water flow passage section is placed over the rotary water wheel.

Regarding the food processing apparatus that is such an embodiment, after separating the rotary water wheel and the mounting shaft between the first joint portion and the second joint portion and removing the rotary water wheel, the passive disk is removed. A maintenance method can be employed in which the mounting shaft is removed from the food processing apparatus.

With this invention, even when a rotating body such as a rotary water wheel used for food processing in a large water tank is removed for maintenance, the work is not hindered by the magnetic force between the passive disk and the operating disk. Furthermore, it is no longer necessary to lift the combined weight of the rotary water wheel and the passive disk at once, and it can be easily removed for maintenance.

Embodiments of the present invention will be described below with reference to the drawings.
A rotation transmission device according to an embodiment of the present invention will be described by taking as an example a mode in which it is mounted in a food processing device 11. The food processing apparatus 11 is shown in a side sectional view in FIG. 1, a top view in FIG. 2, and a front sectional view in FIG. A processing basket 12 with an open top is accommodated and supported in a water tank 13 with an open top. It also includes a drive device 20 that lifts the processing basket 12 to the outside of the water tank 13 and rotates the processing basket 12 so that the open surface of the processing basket 12 is inclined in one direction, that is, tilted.

The processing basket 12 is a basket in which objects 31 to be processed, such as various foods and processed food products, are placed and subjected to cleaning, heating treatment, or sterilization treatment. The processing basket 12 has a bottom surface formed in a mesh shape, like the bottom surface net portion 47, or has a large number of holes (see FIG. 2). This not only allows water to freely flow in and out of the processing basket 12 during processing, but also allows water to be drained by pulling it up from the water tank 13 after processing.

The processing basket 12 is provided with a chute 41 on the edge 40 of the lower side when the basket is tilted. As shown in FIG. 2, this chute 41 has a constricted tip. This chute 41 makes it easy to transfer the object 31 in the processing basket 12 to the next process in the next adjacent food processing device 11 or the like.

The processing cage 12 is provided with a fulcrum pin 43, which serves as a center of rotation during tilting rotation, at a position on the outside of both side surfaces of the processing cage 12 so that the weight can be balanced. By supporting the two fulcrum pins 43, the processing basket 12 can maintain a state with its open surface facing upward. Furthermore, support plates 44 are provided on both sides of the processing basket 12 at positions higher than the fulcrum pins 43 and protrude outward. This support plate 44 is used when tilting the processing basket 12.

The drive device 20 that rotates the processing basket 12 may have the following configurations. A cylinder 25 such as a hydraulic cylinder is connected to a rotation hook 24, and when the rotation hook 24 is pushed, the rotation shaft 21 is rotated. The rotation shaft 21 can rotate about a bearing 22 fixed to the aquarium 13 or the outer aquarium 14. Rotating arms 26 are attached near both ends of this rotating shaft 21. One rotating arm 26 is provided on both sides of the water tank 13 and the outer water tank 14, respectively. The base of each rotating arm 26 is fixed to the rotating shaft 21. On the other hand, a concave support portion 27 is provided near the tip of the rotating arm 26, and the fulcrum pin 43 is rotatably supported by the support portion 27. Further, the rotating arm 26 is not linear, but has an arm bent portion 28 in which the arm is bent in the middle. Furthermore, the pivot arm 26 has an arm tip 29 that extends further beyond the support portion 27 .

On the surface of the processing basket 12 opposite to the chute 41 (the surface of the inlet side edge 49), there is a rotary water wheel, which will be described later, at a position close to the standard water surface height W when the rotary water wheel 73 is not in operation, which will be described later. A second water flow passage port 42 for introducing the water flow generated from 73 is opened.

The water tank 13 that accommodates the processing cage 12 needs to have a shape that can accommodate the processing cage 12. In the embodiment shown in FIGS. 1 to 3, the water tank 13 has a semi-cylindrical shape, and the processing basket 12 has a shape that follows the inner wall of this water tank 13. A drain port 52 is provided at the bottom of the water tank 13. The valve is closed when in use, but it can be opened to drain water after use or when replacing the water.

Further, an outer water tank 14 that is in contact with the water tank 13 is provided so as to surround the outer circumference of the water tank 13 in three directions except for the side where the chute 41 of the processing basket 12 is located. This outer water tank 14 is for collecting water overflowing from the processing basket 12 and sending it to a rotating water wheel 73, which will be described later. Furthermore, a passive rotating section 120 of a rotation transmission device communicating with the rotary water wheel 73 is also provided in the outer water tank 14 .

A partition wall 56 between the aquarium 13 and the outer aquarium 14, which is located on the opposite side of the chute 41, has a notch formed from above at a position corresponding to the second water flow passage port 42 of the processing basket 12. A water flow passage section 55 is provided. A blower outlet 95 of the flow straightening section 74, which will be described later, is placed here, and an upper pressing section 97, which will be described later, is pressed from above to fix the flow straightening section 74.

A front gutter 45 is provided on the introduction side edge 49 of the processing basket 12 opposite to the chute 41 to drain water overflowing from the processing basket 12 into the outside water tank 14. This front gutter 45 rests on a front edge 53 that is the upper end of a partition wall 56 that partitions the water tank 13 and the outside water tank 14. Water overflowing from the front gutter 45 passes through the front gutter net 35 and falls around the rotating water wheel 73 of the outer water tank 14. Also, on the upper edge of both sides of the processing basket 12, on the side closer to the front gutter 45 than the support plate 44, there are side gutters 46, 46 for dropping water overflowing from the processing basket 12 to both sides of the outer water tank 14. is provided. The side gutters 46, 46 rest on side edges 54, 54, which are the upper ends of a side partition wall 57, which is a side wall between the water tank 13 and the outer water tank 14. On the side of the processing basket 12, a side gutter net 36 is provided between the side wall 61 and the side edge 54 to catch the rejects contained in the water falling from the side gutter 46 to the side buffers 62, 68. There is.

The outer water tank 14 surrounds the water tank 13 from three sides: side buffers 62 and 68 extending along the side partition wall 57 of the water tank 13, and a water wheel area 63 along the partition wall 56 from the water tank 13. Among these, a rotary water wheel 73 that generates a water flow and a rectifying section 74 that directs the generated water flow toward the first water flow passage section 55 and the second water flow passage port 42 are provided in the water wheel region 63 in contact with the partition wall 56. It is provided. FIG. 4A shows an enlarged cross-sectional view of the rotary water turbine 73 and the rectifying section 74 in FIG. 1 .

First, fixed stands 71, 71 for raising the ground plane of the rotary water turbine 73 from the bottom are provided near both ends of the water turbine region 63. The rotary water wheel 73 is arranged with a gap between it and the bottom surface of the water wheel region 63 by the fixed base 71. Through this gap, water flows from below over the entire axial direction of the rotary water wheel 73. Each fixed base 71 is provided with overhanging stakes 75, 75 that protrude upward.

A lower plate 72 is provided so as to pass between the fixed stands 71, 71. Fixing holes 76 are provided near both ends of the lower plate 72, and the lower plate 72 is fixed by inserting the overhanging stakes 75 of the fixing base 71 into the fixing holes 76. Sliding bearings 77 are provided upwardly at both ends of the lower plate 72. This consists of a semi-cylindrical receiving part 80 opened upward and fixing pillars 89, 89, and the pillars 89, 89 receive the rotating shaft 83 of the rotary water wheel 73 on both sides.

Further, below the partition wall 56 side of the lower plate 72, a lower rectifying plate 78 is provided that extends toward the bottom surface of the outer water tank 14 over approximately the same length as the axial length of the rotary water turbine 73. Further, the lower plate 72 is formed with a hollowed-out lower plate part 79 on the side far from the partition wall 56.

The rotary water wheel 73 has a rotating shaft 83 that is longer than at least the horizontal length of the first water flow passage section 55, and has a runner (stirring blade) that generates a water flow along the rotating shaft 83. In this embodiment, a rotating shaft 83 has an annular portion 81 extending in the radial direction near both ends thereof. The annular portion 81 is connected to the rotating shaft 83 by a plurality of arm portions 84, and a gap is created between the rotating shaft 83 and the annular portion 81 in the portion where the arm portions 84 are not provided. is formed. On the axial surface of the annular portion 81, a plurality of arcuate blades 82 having an arcuate cross section perpendicular to the axis and extending to another annular portion 81 are provided in the circumferential direction. This will be the runner. This arcuate blade 82 is also not in direct contact with the rotating shaft 83, but is formed so as to create a gap between it and the rotating shaft 83. Further, the concave surfaces of the arcuate blades 82 having an arcuate cross section face the rotation direction of the rotary water wheel 73, and are arranged so as to be able to efficiently receive and send out water. That is, when the arcuate blade 82 turns upward, the concave side face the processing basket 12.

A rotating shaft 83 passing through the rotary water wheel 73 has a sliding surface 86 near both ends sandwiched between flanges 85, 85 provided with a width sufficient to sandwich the sliding bearing 77 in the axial direction. This sliding surface 86 contacts the sliding bearing 77 described above. Further, at one end of the rotating shaft 83, a second joint portion 88 is provided which is connected to a first joint portion 124 of a passive rotating portion 120, which will be described later.

A rectifier 74 that controls the direction of the water flow generated by the rotary water wheel 73 is placed from above the rotary water wheel 73 . The rectifier 74 includes a front plate 92 that covers the water tank 13 side and a back plate 91 that covers the outer peripheral side of the rotary water wheel 73. The upper part of the back plate 91 forms an arcuate section 93 having an arcuate axial cross section and is bent toward the front plate 92 side. On the other hand, more than half of the lower part of the front plate 92 is provided with a hole as a front water intake (not shown). Further, the upper part of the front plate 92 is bent toward the back plate 91 side, and then further folded back toward the partition wall 56 side above the front plate 92, thereby forming a constricted portion 94 between the front plate 92 and the back plate 91. This throttle portion 94 covers half of the entire upper area of the rotary water wheel 73 on the partition wall 56 side. It is desirable for the curved surface of the throttle portion 94 to have a shape that does not collide with the rotating water wheel 73 and to be as close to the outer periphery of the rotating water wheel 73 as possible in terms of water flow efficiency. The tip of the constricted portion 94 is aligned in the same direction as the tip of the arcuate cross-sectional portion 93, and a horizontal slit-shaped air outlet 95 is formed between them. This outlet 95 is inserted into the first water flow passage portion 55 of the water tank 13 described above. The water flow generated by the rotating water wheel 73 passes through the first water flow passage portion 55 via the outlet 95, and is discharged from there to the second water flow passage port 42 of the processing basket 12.

FIG. 4B shows a perspective view of the vicinity of the air outlet 95 of the flow straightening section 74 when viewed from the side opposite to the processing basket 12. An upper pressing portion 97 is provided above near the tip of the air outlet 95 of the flow straightening portion 74 to be pressed from above to fix the flow straightening portion 74 . The upper pressing portion 97 is located on an extension of the partition wall 56 of the water tank 13 and is attached below the front gutter 45 that is a part of the processing basket 12 . When the processing basket 12 is stored in the water tank 13, the upper pressing part 97 fixes the rectifying part 74 from above.

Note that the structure for fixing the rectifying section 74 is not limited to the above structure. For example, a structure may be adopted in which a component corresponding to the upper pressing part 97 is integrally attached above the rectifying part 74 and the upper pressing part 97 is pressed down by the front gutter 45. Alternatively, instead of the front gutter 45, a part covering a part of the upper part of the rectifying part 74 may be extended from the introduction side edge 49 to the position of the front gutter 45, and the rectifying part 74 or an upper pressing part attached to the rectifying part 74 may be installed. 97 parts may be pressed down from above.

Further, holes are made at both axial ends of the rectifying section 74 for passing the rotating shaft 83, and side inlet ports 96 of a size to sufficiently supply water to the rotating water wheel 73 are also formed from these holes. It is provided.

Furthermore, lower hook portions 98 are provided on the lower side near both ends of the back plate 91 to prevent the rectifying portion 74 from shifting in the front direction by being hooked onto the lower plate 72. Furthermore, a rear water intake part 101 for taking water into the rotary water wheel 73 from the front side is provided on the back plate 91 in a manner that is hollowed out from the lower side. The rear water intake section 101 includes a central water intake section 102 provided at the central portion in the axial direction, and a lower rear water intake section 103 provided over the entire axial direction. By supplying water to the rotary water wheel 73 from the rear water intake portion 101 and the side introduction port 96, water supply can be ensured even if the water wheel is rotated at a sufficiently high speed. In addition, a hole may be opened on the opposite side of the rear water intake section 101 of the rectifying section 74 to serve as a water intake section, or other opening methods may be used to ensure water supply.

With this configuration, after use, when the processing basket 12 is raised, the rectifying section 74 that has been pressed down by the upper pressing section 97 can be easily removed by lifting it upward. When the rectifier 74 is removed, the rotary water wheel 73 can be accessed. This rotary water wheel 73 rests on a sliding bearing 77. However, the second joint part 88 that receives the force that rotates the rotary water turbine 73 is combined with the first joint part 124 located on the rotation axis of the passive rotation part 120. Therefore, it is necessary to enable the first joint 124 and the second joint 88 to be separated.

The structure of the rotation transmission device 111 that combines the passive rotation section 120 and the rotary water wheel 73 will be explained. FIG. 5 shows a perspective view of the vicinity of the rotation transmission device 111, FIG. 6 shows a front view, and FIG. 7 shows a plan view. The rotation transmission device 111 has a passive disk 125 equipped with a permanent magnet. Specifically, the provision of a permanent magnet means that the passive disk 125 has a built-in permanent magnet so that lines of magnetic force come out from the surface of the passive disk 125. A working disk 67 equipped with a permanent magnet that attracts the lines of magnetic force to each other is used so as to face the passive disk 125 without contacting it. By rotating the operating disk 67, the passive disk 125 pulled by the magnetic force can be rotated without contacting the passive disk 125.

In order to transmit the rotation from the outside in this way, on the outside of the outer wall 65 of the outer water tank 14, there is a movable disk 67, which has a built-in permanent magnet that attracts the passive disk 125 by magnetic force, at a position opposite to the passive disk 125. A rotating motor 66 is attached. The rotating direction of the rotary water wheel 73 due to this is such that the back plate 91 side faces upward and the front plate 92 side faces downward.

One end of a mounting shaft 126 is joined to the passive disk 125 . The attachment shaft 126 rotates on the same rotation axis as the passive disk 125 rotates. The mounting shaft 126 is rotated by two bearings 127, 127 mounted on the fixed base 121. In addition, a stopper 151 is provided on the mounting shaft 126 to prevent it from coming off from the bearing 127 back and forth in the axial direction with respect to the fixing plate 128 attached to the fixing base 121. At least one resin washer 152 is attached between the stopper 151 and the fixed plate 128 to reduce resistance during rotation.

Furthermore, a first joint portion 124 is formed at the other end of the attachment shaft 126. This first joint part 124 can be combined with a second joint part 88 formed at the end of the rotary water wheel 73, and in the combined state, the rotation of the mounting shaft 126 is connected to the rotary shaft 88 of the rotary water wheel 73. The water is transmitted to the rotary water wheel 73 to enable rotation. In the illustrated embodiment, the second joint portion 88 has a rectangular shape. In contrast, the first joint portion 124 has a cutout shape into which the rectangular portion of the second joint portion 88 can be inserted from a direction perpendicular to the axis. The combination of shapes of the first joint portion 124 and the second joint portion 88 may be reversed.

In this way, it is desirable that the first joint part 124 and the second joint part 88 can be combined not only by movement in the axial direction, but also by sliding in a direction perpendicular to the axis. Further, it is desirable that the first joint portion 124 and the second joint portion 88 engage with each other through a combination of shapes without requiring other fixing means such as screws or additional parts. By allowing them to be combined and separated by sliding in a direction perpendicular to the axis, they can be removed by simply lifting only the part closer to the rotary water wheel 73 than the second joint 88 from the sliding bearing 77. , maintainability becomes better. In addition, when removing it in this way, the angle of the first joint part 124 is adjusted so that the notch is oriented in the vertical direction as shown in FIG. When the rotary water wheel 73 is lifted in this orientation, it can be slid upward from the position where the second joint part 88 engages with the first joint part 124 and can be removed as is.

When the rotary water wheel 73 is removed, it can be lifted separately from the passive disk 125, so that the rotary water wheel 73 will not be attracted by the magnetic force of the operating disk 67 and become stuck. In addition, at the stage of removing the rotating water turbine 73, the passive rotating part 120 including the passive disk 125 remains fixed, so the position of the passive disk 125 shifts toward the outer wall 65 and is captured by the strong magnetic force of the operating disk 67 and removed. There will never be a situation where it becomes difficult. Furthermore, since it can be lifted separately from the heavy passive disk 125, the weight burden when lifting the rotary water turbine 73 is reduced, and the number of people required for maintenance can be reduced.

On the other hand, the passive rotating section 120 from the passive disk 125 to the first joint section 124 can also be separately removed from the attached device. In this embodiment, the attached device is the food processing device 11, and the attached location is the inner bottom surface of one side buffer 68 of the outer water tank 14. A fixed mounting part 130 for mounting and fixing the passive rotating part 120 is attached to this location to be mounted.

The fixed base 121 of the passive rotation unit 120 is provided with a female threaded portion 129 inside thereof in a direction parallel to the mounting shaft 126, and a disk position adjustment screw 123 is inserted into this female threaded portion 129. The disk position adjustment screw 123 has a male threaded portion 141 that engages with the female threaded portion 129 on a part of its outer periphery. A resin pressing portion 144 is attached to the tip of the disk position adjustment screw 123 on the outer wall 65 side. Furthermore, a handle 143 is provided at the other end of the disc position adjustment screw 123, which can be grasped by hand when turning the entire screw. When the handle 143 is rotated, the screw shaft 145 is rotated, and the abutting portion 144 can be extended toward the outer wall 65 or conversely moved away from the outer wall 65. When the pressing portion 144 is extended toward the outer wall 65 based on the position of the female screw portion 129, the passive rotating portion 120 moves away from the outer wall 65. Conversely, when trying to move the pressing part 144 away from the outer wall 65 with reference to the position of the female threaded part 129, the outer wall 65 of the disc position adjustment screw 123 that was preventing the passive rotating part 120 from being attracted by the magnetic force of the operating disc 67 Since the side length is shortened, the passive rotating part 120 approaches the outer wall 65.

A plurality of fixing branches 122 are provided in the axial direction below the fixing base 121 of the passive rotation unit 120, extending in the left-right direction along the outer wall. Note that the left-right direction from the passive disk 125 toward the rotating water turbine 73 is referred to as the left-right direction. The same applies to the following description. FIG. 5 shows an embodiment in which three fixed branches 122a, 122b, and 122c are provided in order from the rotary water wheel 73 side. The passive rotating part 120 is attached to the fixed mounting part 130 via this fixed branch 122.

The fixed attachment portion 130 has a substrate 133 that rests on the inner bottom surface of the device to be attached. Mounting plates 138 are mounted on both left and right ends of the substrate 133 along the axial direction. This mounting plate 138 is for securing a mounting gap 139 for storing the fixed branch 122 described above. Therefore, the height of the mounting plate 138 needs to be higher than the thickness of the fixed branch 122. A holding plate 131 (131a, 131b, 131c) extending from above the mounting plate 138 in the left-right center direction is attached with a mounting gap 139 secured. The substrate 133, the mounting plate 138, and the holding plate 131 are fixed to the inner bottom surface of the device with fixing screws 136 inserted into holes provided at the four corners of the substrate 133.

In the embodiment shown in this figure, three pressing plates 131a, 131b, and 131c are formed so that each of the fixed branches 122a, 122b, and 122c can be pressed from above. Further, each of the holding plates 131a, 131b, and 131c has a notch 132a cut out on the rotary water wheel 73 side so that the fixed branch 122 can pass therethrough when the passive rotating part 120 is attached or removed. , 132b, 132c are formed. Furthermore, an eaves portion 134 is provided on the upper surface of the holding plate 131c located closest to the outer wall of the outer water tank 14 to prevent the fixed branch 122c passing through the notch 132c located closest to the outer wall from being drawn toward the operating disk 67. It is being The eaves portion 134 extends in a direction away from the outer wall side of the outer water tank 14, that is, toward the rotary water wheel 73 side, and the portion overlapping the upper part of the notch portion 132c is provided with an inclined portion 135 such that the upper side becomes further away from the outer wall side. It is being

Further, a terminal position adjustment screw 137 for adjusting the axial position is attached to the movable disk 67 side at the center in the left and right direction of the base plate 133, so as to hit the center in the left and right direction of the fixed branch 122c, and the end position adjustment screw 137 is attached with the tip facing toward the rotating water wheel 73 side. There is. This end position adjustment screw 137 can act as one of the slide fixing parts that keeps the passive rotation part 120 slid toward the outer wall 65 in the position in the operating state.

FIG. 6 shows a front view of the vicinity of the rotation transmission device 111 when the food processing device 11 is operated, that is, the passive disk 125 receives rotation from the operating disk 67 to rotate the rotary water wheel 73, and the height of A-A is shown in FIG. FIG. 7 shows a plan cross-sectional view. After the passive rotating section 120 is mounted on the fixed mounting section 130, the first joint section 124 of the passive rotating section 120 and the second joint section 88 communicating with the rotary water wheel 73 are assembled so that their rotational axes coincide. has been done. The height of the rotating shaft 83 of the rotary water wheel 73 is determined by the height of the receiving portion 80 of the sliding bearing 77, which receives the sliding surface 86 by the pillars 89, 89. Further, the height of the mounting shaft 126, which is the rotation axis of the passive disk 125, is determined by the height of the fixed mounting portion 130, the fixed base 121 of the passive rotating portion 120 attached thereon, and the height of the bearing 127.

Further, the first joint part 124 and the second joint part 88 can rotate even if they are not in complete contact with each other in the axial direction, and even if the passive rotating part 120 moves in the axial direction, a slight movement is allowed. can. The axial position of the passive rotating section 120 is a position where the passive disk 125 can rotate by the magnetic force of the operating disk 67 and is not in contact with the outer wall 65. The closer the passive disk 125 is to the active disk 67, the stronger the magnetic force becomes and the more efficient it is at transmitting rotation, but if it comes into contact with the outer wall 65, it will be subject to friction and will hardly rotate. Therefore, the position is adjusted so that the passive disk 125 is as close to the outer wall 65 as possible and does not come into contact with it. This axial position adjustment is performed by a disk position adjustment screw 123 attached to the fixed base 121.

A BB plane cross-sectional view near the fixing base 121 at the height of the disk position adjustment screw 123 is shown in FIG. 8(a). Further, a cross-sectional view taken along the line CC in FIG. 8(a) is shown in FIG. 8(b). A resin pressing portion 144 provided at the tip of the disk position adjustment screw 123 is pressed against a screw stopper 69 provided on the outer wall 65. A handle 143 is attached to the tip of the disc position adjustment screw 123 on the rotary water wheel 73 side, and by manually rotating the handle 143, the male threaded portion 141 attached to the screw shaft 145 is inserted into the fixed base 121. It can be moved back and forth in the axial direction by engaging the female screw portion 129 in which a hole is formed facing in the axial direction.

When the handle 143 is rotated so that the pressing part 144 protrudes, the passive rotating part 120 moves away from the operating disk 67. The magnetic force between the active disk 67 and the passive disk 125 is so strong that it is difficult to remove them by force if they are close enough to touch. Therefore, by changing the force of rotating the handle 143 into a force that moves back and forth in the axial direction using the female threaded portion 129 and the male threaded portion 141, the passive disk 125 can be easily moved away from the operating disk 67 even with one person's effort. FIG. 9A shows a front view of the passive disk 125 moved away from the operating disk 67 by rotating the handle 143. Further, a bb cross-sectional view in this state is shown in FIG. 9(b). There is a sufficient space between the tip of the terminal position adjustment screw 137 and the end of the fixed branch 122c on the outer wall 65 side, and the passive disk 125 is also sufficiently separated from the outer wall 65. The magnetic force rapidly attenuates as the distance increases, so if you can use the handle 143 to separate the passive disk 125 and the working disk 67 until the distance between them is 20 mm or more, then when you move the passive disk 125 further away from the working disk 67, This can be done by hand without using the handle 143. In the figure, the fixed branch 122c is moved to a position corresponding to the notch 132c, but it is easily possible to further move the fixed branch 122c from here to a position corresponding to the notch 132b. Further, the passive rotation part 120 may be removed from the fixed mounting part 130 by sliding all of the fixed branches 122a, 122b, and 122c in the axial direction and being removed from the mounting gap 139.

Moreover, the passive rotation part 120 can also be removed by lifting it up at the position where the fixed branch 122c corresponds to the notch part 132c. However, at this time, the passive disk 125 is not yet far enough away from the operating disk 67, so if you simply lift it straight up, you will not be able to stop the force that draws the passive disk 125 toward the operating disk 67, There is a risk that the disk 125 may be pressed against the outer wall 65. The inclined portion 135 provided on the lower surface of the eave portion 134 prevents such movement. FIG. 10(a) shows the movement when removing the passive rotating portion 120, which is guided by the presence of the inclined portion 135. Further, an enlarged view of the movement of the inclined portion 135 and the fixed branch 122c is shown in FIG. 10(b), and a perspective view is shown in FIG. 10(c). When the passive rotation part 120 is lifted, the fixed branch 122c slides away from the operating disk 67 along the slope of the slope part 135 of the eave part 134. As a result, the passive disk 125 can be separated from the active disk 67 to a distance where there is almost no possibility of it being attracted to the active disk 67, and the passive rotating section 120 can be safely removed.

Although not shown, the passive rotating part 120 may be slid and lifted until the stationary branch 122c reaches the notch 132b instead of the notch 132c, or even the notch 132a on the rotary water wheel 73 side. In this case, the inclined portion 135 is not particularly used and can be lifted safely. When lifting by minimizing the slide width, the inclined part 135 can be prevented from being drawn to the operating disk 67 and can be lifted safely, and if a sufficient slide width is secured, the inclined part 135 does not have to be used. Can be lifted safely. The maintenance person may select either one. That is, the inclined portion 135 exhibits the effect of ensuring safety when the sliding operation is simplified.

The inclined portion 135 also acts as a guide when attaching the passive rotating portion 120 to the fixed mounting portion 130. When attaching the passive rotating section 120, if the fixed branch 122c is attached directly above the notch 132c, the passive disk 125 is too close to the operating disk 67 and may be drawn. The presence of the eaves 134 has the effect of prompting the operator to try to attach it while avoiding it. The passive rotating part 120 approaches the outer wall 65 from a far position, and lowers it while approaching the outer wall 65 so that the fixed branch 122c is caught on the inclined part 135. It is possible to prevent the situation from being fixed until it comes into contact with the object.

In order to use this rotation transmission device 111, it is installed in the following steps. First, the passive rotation section 120 is attached to the fixed attachment section 130. At this time, either the fixed branch 122c can be hooked onto the inclined part 135 and lowered, or the fixed branch 122c can be inserted into the attachment gap 139 at a position farther from the outer wall than the notch 132a. After attaching the passive rotating part 120 to the fixed mounting part 130, rotate the handle 143 to adjust the position of the pressing part 144 of the disc position adjustment screw 123 to bring the passive disc 125 as close as possible to the outer wall 65 of the outer water tank 14, Stop before contact. This disc position adjustment screw 123, together with the above-mentioned terminal end position adjustment screw 137, functions as one of the slide fixing parts that keeps the passive rotating part 120, which has been slid toward the outer wall 65, at the position in the operating state. The position held by either the disc position adjustment screw 123 or the end position adjustment screw 137 is the position in the operating state. Next, the mounting shaft 126 of the passive rotating section 120 is rotated to adjust the angle so that the notch of the first joint section 124 faces in the vertical direction. Then, the angle of the rotary water wheel 73 is adjusted so that the rectangular portion of the second joint part 88 faces in the vertical direction, and the rotary water wheel 73 is lowered to match the notch of the first joint part 124. At this time, the axial position is such that the sliding surface 86 rests on the receiving portion 80 of the sliding bearing 77. As described above, the rotation of the operating disk 67 is transmitted to the passive disk 125, and the rotation of the passive disk 125 is transmitted from the first joint portion 124 to the second joint portion 88, thereby rotating the rotary water wheel 73, which is a rotating body to be rotated. By rotating the rotary water wheel 73, a sufficient water flow can be generated in the food processing apparatus 11.

When removed after use, the angle between the rotary water wheel 73 and the passive disc 125 is adjusted so that the notch of the first joint 124 and the rectangular portion of the second joint 88 can slide vertically. Then, the rotary water wheel 73 is lifted upward, the second joint portion 88 is extracted from the first joint portion 124, and the rotary water wheel 73 is separated from the passive rotating portion 120 and removed. Next, the handle 143 is rotated to push out the pressing portion 144 of the disk position adjustment screw 123 toward the outer wall 65 of the outer water tank 14, and the entire passive rotating portion 120 is moved away from the outer wall 65. When the stationary branch 122c is slid until it is positioned directly below the notch 132c, the passive rotating section 120 is lifted. The stationary branch 122c is placed against the inclined portion 135 and lifted while moving away from the operating disk 67 to be removed. Alternatively, the fixed branch 122c may be slid until it is positioned directly below the notch 132b or the notch 132a and then lifted, or the fixed branch 122c may be slid until it is completely removed from the attachment gap 139 and then lifted. .

The basic procedure for using the food processing apparatus 11 itself, which employs the rotation transmission device 111 and has the rotary water wheel 73 attached, is as follows. An object 31 to be processed, such as cleaning or heating, is placed in a processing basket 12 housed in a water tank 13. When the rotary water wheel 73 is rotated, the water in the outer water tank 14 is sucked into the rotary water wheel 73, and is introduced from the outlet 95 through the first water flow passage part 55 to the second water flow passage port 42, and the water in the treatment basket 12 is It becomes a water flow that circulates inside. With this water flow, the object 31 to be treated is subjected to treatments such as washing. When the processing object 31 has been processed for a certain period of time, the drive device 20 is driven to rotate the rotating arm 26 upward. Initially, the inclined portion 30 at the tip of the rotating arm 26 is connected to the support plate. 44, the processing basket 12 does not rotate so that its open surface is tilted in one direction, but moves up and down while maintaining its balance. At this time, since water falls from the bottom screen portion 47 into the water tank 13, water adhering to the object to be treated 31 can be removed. Further, by vibrating the rotating arm 26, water can be further shaken off. Thereafter, the processing basket 12 having the fulcrum pin 43 rotatably connected to the rotating arm 26 is rotated, and the object 31 to be processed falls onto the chute 41 to the left in the figure in the case of FIG. . When the dropping is finished, the rotating arm 26 is returned and the processing basket 12 is stored in the water tank 13 again. Thereafter, the processing object 31 can be similarly introduced and processing can be continued.

The apparatus to which the rotation transmission device 111 according to the present invention can be applied is not limited to the above-mentioned food processing apparatus. However, if the rotation transmission device 111 according to the present invention is employed in an environment where frequent maintenance is required in order to process foods that tend to accumulate fats and oils and other food waste, the effects can be fully demonstrated. The above installation and removal can be performed safely and with little effort. In addition, in applications other than food processing equipment, this rotation transmission device 111 is used in situations where a rotating body is rotated in a liquid containing a lot of oil or fat, or a rotating body is rotated in a liquid containing a lot of fibrous dust. It can be used suitably.

Other food processing equipment in which the rotation transmission device 111 according to the present invention is installed include, for example, one in which the processing basket 12 is removed from the food processing equipment 11 described above and food is processed only in the water tank 13. Further, the number of rotary water turbines 73 rotated by the rotation transmission device 111 may not be one. In a food processing apparatus having a plurality of rotary water wheels 73, if the rotation transmission device 111 according to the present invention is provided for each rotary water wheel, each rotary water wheel can be easily removed for maintenance. However, in this rotation transmission device, the passive rotating section 120 including the fixed base 121 requires a certain length in the axial direction, so when arranging a plurality of rotating water turbines 73 in series, It should be noted that no water flow is generated. For example, if the motor 66 and the operating disc 67 are installed in the middle of the device and stored in a storage area with a recessed outer wall toward the inside of the device, then the part where no water flow is generated by the passive rotating section 120 will be moved inside the device. It occurs in the center of the For this reason, if the motor 66 and the operating disk 67 are attached to both ends of the device and the rotational force is transmitted from both the left and right sides to the two rotating water turbines arranged in series, the passive rotating part 120 where no water flow is generated. will be placed at both ends of the device. By keeping the ends of the two rotary water turbines without passive disks as close as possible, the area where no water flow is generated can be made as small as possible. In addition, in this case, it is possible to achieve the same effect as installing a single long rotary water wheel, and since each rotary water wheel can be individually removed, maintenance efficiency is high.
