Description

  The present invention relates to a cleaning device used in a cleaning process for vegetables, fruits and the like.

  Since foods such as vegetables and fruits are directly taken into the human body, strict control on food hygiene is required, and various devices for cleaning the food have been proposed. . As a conventional general vegetable cleaning device, a conveyor for transportation is arranged in a water tank, and a cleaning mechanism such as a wiping cloth, a plate brush, or a rotating brush is installed above the transport surface of the conveyor. A device that removes dirt, deposits, and the like adhering to the surface is known.

On the other hand, for example, Patent Document 1 proposes a technique in which aeration is performed in a cleaning tank to remove foreign matters and the like attached to the surface of an object to be cleaned by rising air. The food cleaning device of Patent Document 1 is provided with an air jetting device that jets air obliquely upward so as to generate a water flow toward the food takeout portion in the washing tank, and the takeout conveyor is submerged at one end in the food takeout portion. It is attached in the state of letting it. The food that has been thrown into the washing tank receives air blow-out from below, removes foreign matter, and is sent to the food take-out part side by a water stream and taken out from the washing tank by the take-out conveyor attached to the take-out part Met.

  However, the conventional general cleaning equipment for vegetables, etc., scrapes off the deposits and dirt on the surface of vegetables etc. with a brush etc., so that human hair, fine sand grains, dust etc. can be reliably removed from the surface of vegetables, etc. It was difficult to remove. In particular, leafy vegetables and the like often have sand or soil bitten between the leaves, so that reliable cleaning is difficult or impossible. When packaged and shipped with foreign objects such as human hair attached to food, all the lots are returned during the consumption process and returned to the manufacturer. There is a risk that. Therefore, the conventional apparatus as described above is often used mainly for primary cleaning with soil, mud, etc. attached after harvesting, and as final cleaning in the cleaning process immediately before shipping packaging. Was inferior in practicality.

  On the other hand, in the cleaning device of Patent Document 1, since air is jetted obliquely upward from the lower side in the tank toward the take-out part, the food is moved in the same direction by the water flow caused by the air. The air jetting force received by the water becomes weak, and it is extremely difficult to remove foreign matter, particularly when human hair or the like is sandwiched and adhered to food. Furthermore, since the foreign matter once removed from the food and floating in the water is caused to flow in the same direction as the food by the water flow or convects in the tank, there is a high possibility that the foreign matter will reattach to the food. Therefore, in the same way as the above-mentioned conventional apparatus, foreign objects such as human hair are often packaged and shipped while attached to food, and all lots are returned in the process of consumption, causing a great deal of damage to the producer. There was a fear. In addition, since an air ejection device and a conveyor are disposed in the cleaning tank, maintenance work including inspection, cleaning, parts replacement, and the like is complicated and difficult. Further, in order to improve the cleaning effect, there can be considered a method in which a cleaning tank is provided long in the conveying direction and the time for applying air to the food is lengthened. However, the entire apparatus is large and expensive. In addition, as described above, there is a possibility that the foreign matter is reattached to the food as described above, and the practicality is low.

  The present invention has been made in view of the above-described conventional problems, and one object thereof is vegetables that can reliably and efficiently remove and wash foreign substances adhering to vegetables, fruits, other foods, or other articles. A cleaning apparatus and a cleaning method are provided. Another object of the present invention is to provide a cleaning apparatus and a cleaning method for vegetables and the like that reduce the risk of redeposition of human hair and the like and improve the cleaning effect. Another object of the present invention is to provide a washing apparatus for vegetables and the like that can be easily maintained. Furthermore, the other object of this invention is to provide the washing | cleaning apparatus of vegetables etc. which can be manufactured with a compact and low-cost structure.

In order to achieve the above object, the present invention always injects the cleaning tank 12 provided in the machine casing 26 and the entire cleaning tank in the lateral direction (F) from the one side to the other side as it is. In this way, the jetting means 14 for generating a one-way cleaning water flow, the overflow unit 34 for discharging water containing light specific gravity foreign matter installed in the cleaning tank 12 on the discharge side of the one-way cleaning water flow, and water discharge containing heavy specific gravity foreign matter A discharge portion 30 including a slit hole 36, an inclined portion 241 provided in the cleaning tank 12 and inclined downward from the cleaning water injection source side toward the discharge portion 30, and an inclined end of the inclined portion. It is a bottom wall 24 composed of a flat portion 242 that is connected and formed flat toward the discharge portion side, and is entirely discharged from the injection side of the washing water through a landing height adjustment mechanism on one end side of the machine frame 26. parts arranged in downward inclined toward the side bottom wall 24 A circulation mechanism 44 that circulates the water discharged from the discharge unit 30 after removing foreign matters to the jetting unit 14 and circulates it, and a large number of thin line frames are vertically arranged by submerging a part of the water in the cleaning tank 12. It is a cylindrical housing framed to form a water flow gap H, and has an inlet opening 68a and an outlet opening 68b for the cleaning object V on one end side and the other end side in the axial direction, respectively, and the rotational axis is unidirectionally cleaned. The object to be cleaned is washed with water from a number of vertical water gaps H while being moved in the axial direction while being moved in the axial direction while being repeatedly swung and moved by rotating the object to be cleaned V in the horizontal direction so as to be orthogonal to the water flow. It is comprised from the washing | cleaning apparatus 10 of vegetables etc. characterized by including the cylindrical housing which wash | cleans the thing V and removes a foreign material. The cleaning apparatus can be widely applied from the first cleaning of foods such as vegetables, seafood, and meat to the final finishing cleaning. The specific shape of the cleaning tank may be elliptical, circular, polygonal, or any other arbitrary shape. The injection means may be, for example, an injection nozzle that is arranged to inject in one direction, and the number, injection force, and the like are appropriately set. Further, for example, a long groove pocket that is long and recessed in the width direction may be provided in the bottom wall of the cleaning tank, and an opening may be formed in the long groove pocket to dispose a discharge pipe that communicates the opening with the buffer tank. Further, an overflow wall on the upper end side, a slit hole on the lower side, and one or a plurality of openings at an intermediate height may be appropriately provided on the facing wall facing the spraying means of the cleaning tank. At that time, a discharge nozzle directed toward the buffer tank may be attached to the intermediate position opening. By providing these, various foreign substances in the cleaning tank can be discharged well.

  In addition, the moving means 20 is good also as having a mechanism to hold | grip or latch the washing | cleaning target object V and to move regularly or irregularly in the flow of water. Moreover, it is good also as the hollow washing water flow gap structure 62 which performs conveyance and holding | maintenance of the washing | cleaning target object V simultaneously in the flow of washing water, and hold | maintains the cleaning target object V inside. In essence, the holding means and the conveying means may be configured separately, but can be easily manufactured by forming an integral structure with the flush water flow gap structure. Further, the flush water flow gap structure 62 may be formed of a cylindrical body (66) that is arranged so that its rotation axis is in the horizontal direction and is rotationally driven. The shape of the cylinder may be a cylinder, a polygonal cylinder, or any other shape. Further, the cleaning water flow gap structure 62 may be formed of a frame having a thin line frame as a framework. The material of the washing water flow structure may be arbitrary as long as it has water resistance and has some strength, such as metal such as stainless steel, plastic synthetic resin, bamboo, and the like. In addition, the cleaning water flow gap structure 62 has a plurality of vertical projections (L1, L2, L,...) That block the flow in a vertical line in cross section with respect to the flow of cleaning water from the lateral direction. ) And zero or several projected horizontal stripes connected to the projected vertical stripes in an intersecting manner. It is preferable that the number of projected horizontal filaments is as small as possible so that foreign matter is not caught on the gap structure and the foreign matter is prevented from reattaching. In addition, the cleaning water flow gap structure 62 may be formed of a spiral linear tube body 66 that circulates so that the conveyance direction of the cleaning object V is the traveling direction. The spiral gap may have an arbitrary width of about 1 mm to 15 mm, for example, and may be set to any other size. The spiral gap may be formed to be constant as a whole, but the width may be changed regularly or irregularly. In addition, a support mechanism 64 that rotatably supports the cleaning water flow gap structure 62 may be provided in a state where the cleaning water flow gap structure 62 is disposed in a direction intersecting with the flow of the cleaning water. Good. The support mechanism may be installed either inside or outside the cleaning tank. When arrange | positioning in a washing tank, it is good to provide in a side wall side rather than the center side of a washing tank so that the flow of the water from an injection means may not be disturbed. Alternatively, the cleaning water flow gap structure 62 may be driven to rotate only by placing the cleaning water flow gap structure 66 on the support mechanism 64. Further, the cleaning water flow gap structure 62 may be detachably supported by the support mechanism 64. For example, prepare various types of cleaning water flow gap structures with different flow gap sizes, thin wire thicknesses, etc., and replace them arbitrarily according to the type of cleaning object. It is good to do. In addition, the cleaning water flow gap structure 62 may be provided with a locking portion 86 that rakes up the cleaning object V as it rotates and drops it. The locking portion is, for example, a flat or curved plate member, a net plate that allows the flow of water, a comb-like body, a hook body, a rod body, a bucket, a protrusion, or any other gripping or locking. It may be a thing. Further, the locking portion may be formed by deforming a part of the cylindrical body. The locking part may also serve as the conveying means. Further, the cleaning object V is connected to the cleaning object inlet opening 68a and the discharge opening 68b of the cylinder (66) as the cleaning water passage gap structure 62, and the cleaning object V is continuously input to the cleaning water passage gap structure 62. External discharge means (88a, 88b) for discharging are provided, and the locking portion 86 and the discharge-side external transfer means 88b are linked to rotate the cleaning water flow gap structure 62 and transfer the discharge-side external transfer means 88b. The transfer from the cleaning water flow gap structure 62 to the external transfer means may be performed only by driving. For the purpose of reliably removing foreign matter from the object to be cleaned, the object to be cleaned can be manually inserted into the cleaning water flow gap structure, but by providing an external transfer means, the cleaning process can be automated, and the operator Labor is reduced. As an external conveyance means, for example, a conveyor such as a belt conveyor, a roller conveyor, a chain conveyor, an inclined shooter, or any other configuration may be used.

  The present invention relates to a cleaning tank, jetting means for injecting cleaning water in the lateral direction in the cleaning tank, and transport for transporting the cleaning target in the cleaning tank so that the cleaning target receives the flow of the cleaning water from the crossing direction. Means, holding means for holding the object to be cleaned not to be washed away, and moving means for forcibly changing the holding position of the object to be cleaned by the holding means. By comprising a washing device for vegetables, etc., the washing effect is improved by moving the washing object in the crossing direction with respect to the flow of water in a fast direction in the washing water, and the washing object The foreign matter adhering to the surface can be reliably removed and cleaned. In particular, even when foreign matter that is difficult to remove, such as human hair, is attached, it can be removed and cleaned effectively. In addition, the object to be cleaned is transported in a direction crossing the water flow, and the removed foreign matter is flowed by the flow in only one direction, so that the foreign matter can be prevented from reattaching to the cleaning target. Therefore, for example, it can be effectively used for a cleaning process that requires special hygiene attention, such as immediately before package shipment. In addition, the number of workers in the cleaning process can be reduced, which is labor-saving and efficient.

  Further, the moving means 20 has a mechanism for gripping or locking the object to be cleaned and moving the water object regularly or irregularly in the water flow, so that the object to be cleaned in the water flow is simply transported. Differently, the cleaning object itself can be forcibly moved to greatly improve the cleaning effect.

  Further, the cleaning water flow gap structure has a plurality of projected vertical lines that block the flow in a vertical line in cross section with respect to the flow of the cleaning water from the lateral direction, and intersects the projected vertical lines. By including a connected zero or several projected horizontal filaments, foreign matter caught on the filaments along with the rotation of the cleaning water flow gap structure can be carried upstream of the cleaning water jet. It is difficult to fall into the gap structure and it is possible to prevent foreign matters from reattaching to the object to be cleaned. In addition, the cleaning effect can be maintained with a configuration in which the area for blocking the cleaning water flowing through is as small as possible.

  In addition, the cleaning water flow gap structure is composed of a spiral wire tube that circulates so that the direction of conveyance of the object to be cleaned is the traveling direction, so that the gap structure can be conveyed and held with a simple structure. Can be specifically configured. Further, it is possible to form a cylindrical body having no connection point between the filaments, and to form the entire cylindrical body as a substantially projected vertical filament with respect to the flow of water. The foreign matter is less likely to be caught on the spiral wire cylinder, and the foreign matter can be prevented from reattaching to the object to be cleaned.

  In addition, with the cleaning water flow gap structure disposed in the direction intersecting with the flow of the cleaning water, a support mechanism that rotatably supports the cleaning water flow gap structure is provided. The washing water flow gap structure can be rotated while being stably supported, and the conveying means, the holding means, and the like can be reliably acted on for effective washing.

  In addition, the cleaning water flow gap structure can be rotationally driven by simply placing the cleaning water flow gap structure on the support mechanism, thereby installing the cleaning water flow gap structure. Can be done easily and can be prepared in a short time. In addition, since a complicated connection operation is not required, a structure in which the gap structure can be freely attached and detached can be easily realized.

  Further, by adopting a configuration in which the cleaning water flow gap structure is detachably supported with respect to the support mechanism, maintenance including inspection, cleaning, replacement, and the like can be easily performed.

  In addition, the cleaning water flow gap structure is provided with a locking part that lifts and removes the cleaning object as it rotates, thereby forcing the cleaning object in the flow of water. The structure to be moved is simplified, and low-cost manufacturing is possible.

  In addition, there is provided an external conveying means connected to the cleaning object introduction opening and the discharge opening of the cylindrical body as the cleaning water flow gap structure to continuously input and discharge the cleaning object to and from the cleaning water flow gap structure. Then, the locking portion and the discharge-side external transfer means are linked to each other so that the cleaning water flow gap structure is moved from the wash water flow gap structure to the external transfer means only by the rotation of the wash water flow gap structure and the transfer drive of the discharge-side external transfer means. By performing the loading, it is possible to continuously perform the process of loading the object to be cleaned, the cleaning process, and the discharging process, and to automate the entire cleaning operation to improve efficiency and labor saving. Also, fewer cleaning workers are required. Furthermore, the structure for transferring from the cleaning water flow gap structure to the external conveying means can be manufactured with a simple structure. In addition, it is possible to specifically realize the configuration including the external transport unit while maintaining the detachable configuration of the gap structure.

  In addition, the cleaning water is jetted so as to be applied in a direction substantially orthogonal to the direction in which the cleaning target is transported, so that the cleaning target is satisfactorily maintained while maintaining the jet power of the water received by the cleaning target. Can be transported and cleaned effectively.

  Further, the present invention is directed to injecting the cleaning water into the cleaning tank in the lateral direction, and injecting the cleaning object into the spiral filament body having a through-flow gap for the cleaning water from the lateral direction. Consists of cleaning methods such as vegetables that move the object to be cleaned while rotating the tube while rotating the tube, so that foreign objects can be reliably removed from the object to be cleaned and reattachment of foreign objects can be prevented. , Can be cleaned effectively.

  In addition, by rotating the spiral filament body, the object to be cleaned is advanced by itself, transferred to the carry-out process at the discharge port, and the washing operation is performed continuously. Efficiency and labor can be saved.

As shown in FIGS. 2 and 3, the discharge unit 30 is a discharge unit that discharges the cleaning water sprayed from the spray unit 14 to the outside of the cleaning tank 12. In this embodiment, the overflow part 34 provided in the 2nd side wall 22b side and the slit hole 36 are included. The overflow portion 34 has an overflow promoting wall 38 that is provided at the upper end portion of the second side wall 22b and rises and expands in the overflow direction. Wash water containing light specific gravity foreign substances such as human hair floating on the liquid surface overflows to the buffer tank 28 side through the overflow promoting wall 38, and is collected by a collection means 40 such as a wire mesh provided in the buffer tank 28. It is collected. The slit hole 36 is a hole that is long in the lateral direction provided at the center position in the width direction on the bottom wall 24 side of the second side wall 22 b, and discharges foreign matters having a large specific gravity component such as a sand component to the outside of the cleaning tank 12. The slit width of the slit hole 36 may be set arbitrarily, for example, with a hole of about 0.5 mm to several millimeters. The slit hole 36 may be provided with only one slit hole over the substantially entire width of the cleaning tank 12 or may be provided with a plurality of two, three, four or more.

  As shown in FIG. 2, the buffer tank 28 is a tank that once collects the water released from the cleaning tank 12 and returns it to the circulation mechanism 44 side for circulating the collected water. In the present embodiment, the buffer tank 28 is provided with a collection means 40 such as a wire mesh at an intermediate height, and is divided into an upper chamber 281 and a lower chamber 282 in the vertical direction. In the buffer tank 28, the suction part of the circulation mechanism 44 is disposed in the lower chamber 282, and the upper chamber 281 receives the water discharged from the discharge part 30 of the cleaning tank 12 and passes it through the collecting means 40. When the foreign substance is discharged from the discharge portion 30 after flowing to the chamber 282 side, it is collected by the collecting means 40 and finally removed. In the present embodiment, the upper chamber 281 is provided with a filter case 42 having an upper surface opening whose bottom wall is made of a metal mesh, and is received by the receiving portion 46 on the buffer tank 30 side so as to be freely inserted into and removed from the upper chamber 281. ing.

The lower chamber 282 is provided with an overflow pipe 52 with an open / close cock for maintaining the water level, and a drain pipe 54 with an open / close cock is also provided.

  As shown in FIG. 2, the circulation mechanism 44 collects water discharged into the buffer tank 28, supplies it to the injection pipe 32 by pressure, and recirculates water from the discharge unit 30 from the injection means 14 as washing water. Means. In the present embodiment, the circulation mechanism 44 includes a return pipe 56 that returns the water in the buffer tank 28, a circulation pump 58 that is connected to the return pipe 56, and injection nozzles 32 a and 32 b that are connected to the circulation pump 58. And an injection pipe 32. A detachable filter cap 60 is attached to the tip of the return pipe 56.

  In the present embodiment, for example, as described above, the water flow mechanism including the cleaning tank 12, the injection unit 14, the discharge unit 30, the buffer tank 28, and the circulation mechanism 44 is provided. The object to be cleaned V is cleaned together with the conveying means 16, the holding means 18, and the moving means 20 in a fast water flow in one direction in the cleaning tank 12. The water flow mechanism is not limited to the above-described configuration, and may have at least the cleaning tank 12 and the injection unit 14, and other configurations may be arbitrary.

The transport means 16 is a transport means for transporting the cleaning object V in the cleaning tank 12 while the cleaning object V receives the flow of cleaning water from the crossing direction. The holding unit 18 is a holding unit that holds the cleaning object V that is being conveyed by the conveying unit so that it is not flowed in the direction in which the cleaning water flows. In this embodiment, as shown in FIGS. 1 and 2, the conveying means 16 and the holding means 18 are combined with one structure disposed in the cleaning tank, and the flow of cleaning water from the injection means 14. A hollow cleaning water flow gap structure (hereinafter referred to as a “gap structure”) 62 that simultaneously conveys and holds the cleaning object V and holds the cleaning object V therein is included. In the present embodiment, the gap structure 62 as the transport means 16 is set so that the transport direction is substantially orthogonal to the jet direction F of the cleaning water from the spray means 14, and the third side wall of the cleaning tank A direction from 22c toward the fourth side wall 22d is defined as a conveyance direction X. The gap structure 62 as the holding means 18 reliably maintains the cleaning water jetting force received by the cleaning object and the conveying direction of the cleaning object. In the present embodiment, the gap structure 62 is a cylindrical body that is arranged so that the rotation axis thereof is in the horizontal direction and is rotationally driven, and is rotatably supported via the support mechanism 64.

  As shown in FIGS. 1, 2, and 4, the gap structure 62 is formed of a frame having a thin wire frame as a framework, and in the present embodiment, is formed of a spiral filament tube 66 formed in a cylindrical shape. The spiral filament 66 is disposed with its both ends facing the third and fourth side walls 22c and 22d of the cleaning tank and the cylindrical central axis facing sideways, and the rotation axis is set toward the transport direction X. . The spiral filament 66 has a substantially lower semicircle disposed in the cleaning tank 12 and an upper semicircle protruding from the upper surface of the cleaning tank. At the same time, at least the lower side space of the spiral filament 66 is disposed below the height of the jet port of the jetting unit 14 so that the cleaning water from the jetting unit can reliably hit the object to be cleaned inside the cylinder. Is set. The spiral filament body 66 is a cylinder body that forms a spiral that circulates so that the direction of conveyance of the object to be cleaned is the traveling direction, and the spiral filament cylinder body 66 is cleaned by rotating the spiral filament cylinder body 66. The object V is advanced in the transport direction. The spiral filament 66 has a spiral gap H set so that the cleaning object does not flow while allowing the cleaning water to pass therethrough. The spiral gap H is set to a width of about 5 mm in the case of an object to be cleaned of a certain size such as radish and carrot. The filaments forming the spiral filament cylinder 66 are made of, for example, a metal wire having a diameter of about 3 to 5 mm, and the spiral filament cylinder is bent by its weight even if an object to be cleaned is put inside. Those having such strength are suitable. The gap between the spiral filaments and the diameter of the cleaning are appropriately set depending on the size, shape, type, etc. of the cleaning object V. Both ends of the spiral wire tube body 66 are opened, and a ring-shaped metal frame ring portion 68 having a certain thickness is connected to the outside while being connected to the outside. Openings at both ends of the spiral filament tube serve as a cleaning object input opening 68a and a discharge opening 68b, respectively.

  Further, the spiral linear cylinder 66 is formed so that the adjacent filaments are in a substantially vertical direction around the spiral. That is, in FIG. 5, the cleaning water is jetted toward the front side of the page, and the spiral filament 66 has a plurality of vertical projections L1 and L2 in a vertical line shape in cross section with respect to the flow of the cleaning water. , L3,... Thereby, the shielding area which crosses the flow of the washing water accompanying rotation of a spiral filament can be decreased, the fall of the flow rate of the washing water injected can be prevented as much as possible, and a detergency can be maintained. Further, when a foreign matter such as human hair is caught on the spiral wire cylinder 66, even if the position of the wire changes in phase with the rotation of the spiral wire tube, the foreign material hardly moves with the wire. Therefore, it is possible to prevent the foreign matter caught on the filament from being carried to the upstream side of the jet of the cleaning water or falling into the cylindrical body so that the foreign matter is reattached to the object to be cleaned. The gap structure may have, for example, a projected horizontal line portion, but human hair caught on the horizontal line intersects and returns to the upstream side of the jet by rotation of the gap structure, and again adheres to the object to be cleaned. Therefore, it is preferable that the projected horizontal line portion is small. By adopting a spiral filament tube as in the present embodiment, it can be formed only by the projected vertical filament part as a whole while being inclined slightly obliquely in the cross section with respect to the flow of water, and there are few and simple connection points. Can be realized with a structure. Note that the flush water flow gap structure is not limited to the above-described spiral filament tube body, and, for example, a plurality of vertically arranged metal wire rings are arranged concentrically and laterally, and they are crossed. It is good also as connecting with the metal wire of the horizontal direction which aimed at, and comprising a cylinder. In addition, the gap structure may be configured as a grid-shaped or wire-mesh-shaped eye frame, or any other structure.

  The support mechanism 64 is a support unit that rotatably supports the gap structure 62 in a state where the gap structure 62 is arranged in a direction intersecting with the flow of the cleaning water. In the present embodiment, the support mechanism 64 includes a support arm 70 disposed in the cleaning tank, a rolling member 72 supported by the support arm 70 so as to be freely rollable, and a spiral filament as a gap structure 62. And a drive rolling member 74 that rotationally drives 66. The support arm 70 is made of, for example, a metal plate or a bowl-shaped member formed in an approximately L shape, and the third side of the cleaning tank is disposed while the horizontal side portion 70a is disposed near the bottom wall side of the cleaning tank 12. It is being fixed to the 4th side wall 22c, 22d side. The rolling member 72 is made of, for example, a metal roller body, and is rotatably supported on the extended end side of the horizontal side portion 70a of the support arm. The drive rolling member 74 is disposed near the upper edge of the cleaning tank in the vicinity of the L-shaped upper end side of the support arm 70. In FIG. 2, for example, the rolling member 72 is disposed on the left side of the vertical plane along the rotation axis of the gap structure 62, and the driving rolling member 74 is disposed at a relatively high position on the right side. Even if 66 receives the flow of water, it can support stably. The drive rolling member 74 is made of, for example, a rubber roller body made of urethane rubber or the like, and is fixed to the drive shaft 76. The drive shaft 76 is pivotally supported by a bearing 77 provided at the upper edge of the cleaning tank at both ends, and a driving force is transmitted from a rotary drive device 78 via a sprocket 82 fixed to one end. The rotation drive device 78 includes, for example, a motor and a speed reduction mechanism, and is fixed on a support plate 80 attached to the side of the cleaning tank. The rotary drive device 78 is connected to the sprocket 82 of the drive shaft 76 by an endless chain 84. The support mechanism 64 allows the frame ring portions 68 on both ends of the spiral filament tube 66 to be received by the rolling member 72 and the drive rolling member 74 while circumscribing them. Is supported in a hollow shape in the washing tank. That is, the spiral filament 66 is detachably attached to the support mechanism 64, and the spiral filament 66 can be driven to rotate only by placing the spiral filament 66. Accordingly, the attachment / detachment operation can be easily performed, and maintenance and the like can be easily performed. When the drive rolling member 74 is driven to rotate, the frame ring portion 68 is rotated by the frictional force of the rubber, and the spiral filament 66 is rotated. In the present embodiment, the rotation direction of the spiral filament 66 is a left rotation in FIG. 2, and the movement direction of the submerged lower end side is set to move in substantially the same direction as the injection direction F. .

  As shown in FIGS. 2, 5, and 6, the moving unit 20 moves the holding position of the cleaning object by the holding unit 18 so as to be forcibly changed. In the present embodiment, the moving means 20 includes a locking portion 86 provided in the gap structure 62. The locking part 86 scoops up the cleaning object V with the rotation of the gap structure 62 and causes it to fall off. In the present embodiment, the locking portion 86 is a plurality of rafts projecting toward the central axis while the locking surface is directed in the axial direction on the inner side of the spiral filament as the gap structure. Includes board. For example, the locking portions 86 are provided intermittently along the inner peripheral surface of the cylindrical body, and are arranged regularly or irregularly in the axial direction, that is, in the transport direction. The locking portion 86 is swept up to a height at which the cleaning object V positioned on the lower side inside the spiral filament tube is locked with the latching surface as the spiral filament tube rotates. When the rotation further proceeds, the supporting force is released, and it is dropped and separated by gravity and placed in the water again. In this way, foreign substances such as human hair that improve the cleaning effect and are difficult to be separated from the cleaning target by moving the cleaning target regularly or irregularly while receiving the cleaning water from the lateral direction while transporting the cleaning target. It can be released well. Note that the locking portion may be set to an angle that moves the cleaning target in the transport direction when the object to be cleaned is dropped and removed, and the set angle may be freely changed.

  Further, in the present embodiment, as shown in FIGS. 1, 2, and 5, the input-side external transfer device 88a is provided in the input opening 68a of the spiral filament 66 and the discharge-side external transfer device 88b is provided in the discharge opening 68b. Are connected to each other. The external transfer devices 88a and 88b are external transfer means for continuously charging and discharging the cleaning object V to and from the spiral wire cylinder. The external transfer devices 88a and 88b are made of, for example, a belt conveyor, and the transfer surface is a metal frame with casters in a state where the heights of the input opening 68a and the discharge opening 68b of the gap structure 62 are matched on the upper edge side of the cleaning tank. It is supported by the frame 90. The input-side tip of the input-side external transfer device 88a is set at the input opening position of the spiral wire tube. On the other hand, the distal end of the discharge-side external transfer device 88b is arranged in a state of protruding into the inside from the discharge opening 68b of the spiral filament 66. Therefore, the cleaning object V transported to the discharge opening side in the spiral filament 66 is swept up by the locking portion 86 on the discharge opening side, and then the tip end portion of the discharge-side external transport device that has oozed out. Is dropped on the transfer surface. That is, the locking portion 64 and the discharge-side external transfer device 88b are linked with each other on the discharge opening side to continuously transfer the object to be cleaned from the gap structure to the external transfer device. As a result, it is possible to automatically and continuously perform the process of loading, cleaning, and discharging the object to be cleaned, saving the labor of the cleaning operation, and cleaning the object to be cleaned efficiently, requiring few workers. be able to.

  As shown in FIGS. 1 and 2, a cover plate 92 is disposed so as to cover the jetting unit attachment side of the cleaning tank 12, and a cover plate 93 is disposed so as to cover the upper side of the buffer tank 28. Reference numerals 94 and 96 denote casters, and the landing height of the rear casters 96 can be adjusted with respect to the machine casing 26.

  Next, the effect | action of the washing | cleaning apparatuses, such as vegetables which concern on this embodiment, and the washing | cleaning method are demonstrated. As shown in FIG. 2, the spiral filament is rotated while the cleaning water is sprayed laterally from the cleaning means into the cleaning tank. The object to be cleaned is continuously thrown into the spiral striated tube through the feeding-side conveying device. As shown in FIGS. 5 and 6, the object to be cleaned is supplied with the jet cleaning water that passes through the gap between the spiral filaments from the lateral direction, and the object to be cleaned becomes the cleaning water. The object to be cleaned is gradually transported in the transport direction along the spiral rotation direction by rotating the spiral wire cylinder itself while being held so as not to flow. Furthermore, the object to be cleaned is swung up by the engaging portion as the spiral wire cylinder rotates, and the dropping and releasing operation is repeated. By cleaning the object to be cleaned in this way, foreign matters can be reliably removed from the object to be cleaned. The foreign matter removed from the object to be cleaned flows along the fast side of the cleaning water toward the second side wall, and is discharged from the discharge section to the outside of the cleaning tank without convection in the cleaning tank. Since the flow of the cleaning water, that is, the direction in which the foreign object flows and the moving direction of the cleaning object are in the crossing direction, the foreign object once removed can be prevented from reattaching to the cleaning object. The object to be cleaned, which is transported to the discharge opening side while being cleaned inside the spiral filament, is lifted up by the engaging portion on the discharge opening side, dropped onto the transport surface of the discharge-side external transport device, and is discharged to the outside of the discharge side. Transferred to the transfer device. Thereby, the washing | cleaning process and discharge | emission process by a washing | cleaning apparatus can be automated from an injection | throwing-in process, and cleaning work can be made efficient and labor-saving.
