DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning apparatus for cleaning an object to be cleaned in a generally cylindrical container used for feeding food such as cans.

[0002]

2. Description of the Related Art As an apparatus for cleaning containers used for feeding food such as cans, there is, for example, Japanese Utility Model Laid-Open No. 1-149765 "Canning apparatus". This invention is based on a rotating nozzle pipe and a brush attached to the tip of the nozzle pipe.
Rotation is performed by the reaction force of the cleaning water jetted from the nozzles, and the cleaning is performed by automatically rotating the brush while contacting the brush while spraying the cleaning water on the object to be cleaned, thereby achieving labor saving in the cleaning operation.

As an apparatus for cleaning an object to be cleaned by spraying cleaning water from a rotary nozzle without using a brush, there is Japanese Utility Model Application Laid-Open No. 147357/1985, "Canning Cleaning Pretreatment Apparatus".

[0004] As a device for cleaning an object to be cleaned by connecting a brush to a rotating device, rotating the brush, and pressing the brush against the object to be cleaned,
Japanese Utility Model Application Laid-Open No. 62-192356 "Container cleaning device" is available.

[0005] In any of the prior art examples, in order to solve the problem that a sufficient cleaning effect cannot be obtained with a cleaning apparatus that performs cleaning by spraying cleaning water in a shower shape while transporting an object to be cleaned. It was devised.

[0006]

The food cans used for school lunches are required to be heat-retaining, easy to carry, and durable. Therefore, a thin metal container is coated with a surface coating such as alumite. That is used. In addition, there are many kinds of foodstuffs for feeding in recent years, and dirt on food cans that are returned to the cleaning site after feeding and are processed has a strong adhesive property and is difficult to wash.

[0007] In the above prior art examples, the shape and structure of the cleaning brush are not particularly limited. But,
A brush in which a hard linear material is implanted may damage the surface coating of the can when the rotational force is too high, and may cause a problem in safety. Also, brushes with a hard wire material implanted in a densely packed area will "slack" when pressed against the object to be cleaned.
Occurs, the original state cannot be restored, and there is a problem in durability.

[0008] The prior art example 1-149765
In the “can cleaning device”, the rotating force of the brush is obtained by the jet reaction force of the nozzle of the rotating pipe, so it is necessary to consider the mounting angle of the nozzle to obtain the jet reaction force, and furthermore, the cleaning of the brush In order to improve the operation, it is necessary to provide a nozzle for spraying the cleaning water onto the object to be cleaned, so that the injection pressure of the nozzle for obtaining the reaction force decreases, and the rotational force of the brush is limited. On the other hand, if the rotational force of the brush is too strong, it is very difficult to adjust the rotational force.

The above-mentioned prior art example is disclosed in Japanese Utility Model Publication No. 60-147357.
The 食 can cleaning pretreatment device 」is to wash the object to be cleaned by spraying cleaning water with a concentric rotating nozzle, but is usually connected to a high pressure pump to obtain the jetting power of the cleaning water from the rotating nozzle. Used. Therefore, the rotation speed of the nozzle is fast, the point of application of the washing water to the object to be washed is constant and acts continuously, and in combination with the strong washing water collision force,
The cleaning water does not form a flow along the object to be cleaned and forms a water film, so that the subsequent cleaning water cannot act on the surface to be cleaned. Further, in the case where dirt adheres to the entire surface of the object to be cleaned, it is impossible to use the cleaning water of the rotary nozzle on the entire surface. In this prior art, there remains a problem of uneven cleaning.

The above-mentioned prior art example is disclosed in Japanese Utility Model Application Laid-Open No. 62-192356.
Is to drive the brush in the cleaning tank and wash the object to be cleaned in the cleaning tank. However, considering the detailed description of the invention, the brush rotating means is disposed outside the cleaning tank and The brush rotating shaft and the bearing, which are connected to the brush in the tank and penetrate the cleaning tank in practical use, require sufficient sealing measures. Further, since the washed dirt stays together with the cleaning water in the cleaning tank, there is a problem that the dirt re-adheres to the object to be cleaned.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has studied the structure and material of a brush, the structure of a rotating means of the brush, and the like, and has provided a meal-coated food made of a metal material. An object of the present invention is to provide a cleaning device for a container such as a can, which completely cleans the container such as a can used by a rotating brush and washing water without damaging the surface of the container.

[0012]

According to a first aspect of the present invention, which is directed to a cleaning apparatus for a container such as a food can, for achieving the above object, a bar having a pipe inserted therein and four corners of an object to be cleaned are provided. A mounting portion of the object to be cleaned made of a resin system to be supported, a device for transporting the object to be cleaned composed of a chain, and the transporting means are horizontally opposed to each other, and the contact surface with the object to be cleaned is rubber on the upper side. It is composed of a system, a pressing means that can move up and down, a water guide wall having two lower and upper stages and a rotating blade and a water opening part is provided on the upper side, and a nozzle for colliding water with the rotating blade on the side wall is provided. A casing provided on the side wall, a casing lid for sealing the opening, a rotating drive blade and a hollow drive shaft penetrating the axis of the casing lid to rotate the brush and the casing, and attached to the casing lid shaft. Fixed gear and drive shaft A hydraulic motor consisting of a rotating shaft provided with a plate and a rotating gear meshing with a fixed gear provided on the plate, and a mounting position adjustable on the rotating shaft of the hydraulic motor, which is flexible and elastic. This is a cleaning device for containers such as food cans, which is configured by a brush in which a rubber-based or resin-based cleaning material that can be deformed is planted.

The brush is disclosed in Japanese Patent Application Laid-Open No. 8-241.
93 "Equipment for washing dishes and the like" and JP-A-9-276204
The brush disclosed in "Brush for cleaning containers such as cans" may be used. The material of the brush flock material for the brush is rubber-based,
It is possible to use polyurethane, polyethylene, etc. for resin based resin such as in-prene rubber, butyl rubber, silicon rubber, and natural rubber. However, food hygiene can be ensured, and there is flexibility and elastic deformation. No cleaning effect can be expected, dirt does not adhere to the flocked part,
Silicon rubber is most suitable for cleaning containers such as cans.

JP-A-8-2419 disclosed by the applicant of the present invention.
In 3 "Dishwashing apparatus", a hydraulic motor attaches a brush to a drive shaft, presses the brush against the dish, and cleans the dish with washing water. If the object to be washed is tableware, the washing area is small, and if the brush suitable for the shape and size of the dish is rotated concentrically with the drive shaft of the hydraulic motor, the brush flocking section acts on the entire surface of the object to be washed. It is possible to do. However, when the object to be cleaned is a can, etc., the cleaning area becomes large, and in a device for cleaning by rotating the brush concentrically with the drive shaft of a hydraulic motor, if the brush is not enlarged, the entire surface of the cleaning surface of the object to be cleaned is cleaned. It is not possible for the flock to act. Increasing the brush size increases inertia and reduces the torque of the hydraulic motor, so it is necessary to consider increasing the torque of the hydraulic turbine at the same time. In addition, since the washing time is also limited, the number of times of contact between the washing surface and the flocked portion of the brush must be increased, that is, the rotation speed of the brush must be increased. Therefore, the number of times of contact between the cleaning surface and the flocked portion is reduced, and a sufficient cleaning effect cannot be obtained.

Therefore, in the apparatus for cleaning containers such as cans of the present invention, the brush is not attached to the drive shaft of the hydraulic motor, but is attached to a plurality of rotation shafts provided on a plate connected to the drive shaft. Since the rotation gear of the rotation shaft meshes with the fixed gear, when the drive shaft rotates, the rotation shaft rotates while rotating around the outer periphery of the fixed gear, that is, performs planetary motion. Drive shaft 1
The rotation shaft can rotate several times as much as the rotation, and the brush attached to the rotation shaft can contact the cleaning surface at several times the rotation speed than when the brush is attached to the drive shaft. .

Since the drive shaft is hollow,
The washing water ejected from the nozzle provided on the casing side wall collides with the rotating blade, and the rotating force rotates the rotating blade, and the driving shaft connected to the rotating blade obtains the rotating force. The water that collides with the rotor blades moves from the discharge portion of the guide wall to the lower stage of the casing, and is discharged toward the cleaning surface of the object to be cleaned through the hollow portion of the drive shaft due to the head pressure. The rotation of the drive shaft causes the rotation shaft to rotate at several times the speed, so that the brush rotates in contact with the cleaning surface of the object to be cleaned, and the cleaning water is sprayed from the drive shaft to the cleaning surface. Since the force simultaneously acts on the dirt on the cleaning surface of the object to be cleaned, a good cleaning effect can be obtained.

It is more preferable to attach a cap with a nozzle tip attached to the washing water discharge portion of the drive shaft, and spray the washing water with a brush to aim at the hardest washing portion such as the bottom side corner of the article to be washed. It is possible to obtain a good cleaning effect.

The present invention is intended to clean a generally cylindrical container such as a food can for feeding, and a hydraulic motor is provided with a driving device such as an air cylinder or the like which is capable of reciprocating operation and horizontally moved. Is connected to the elevating means that moves up and down, so that the rectangular container can be washed.

In a second aspect of the present invention, a plurality of drainage pipes are provided on a side wall other than a side wall of a casing provided with a nozzle for impinging cleaning water on a rotating blade of a hydraulic motor. It is a washing device for containers such as canned food.

As described above, the food cans used for lunch are thin, surface-coated, and lightweight. Therefore, if the rotational force of the brush is too strong, the food can is rotated with the rotation of the brush or shaken by centrifugal force. Therefore, it is necessary to increase the holding force of the pressing means for holding the object to be cleaned. However, there is a limitation, and if it is too strong, the food can may be deformed or damaged. Therefore, there arises a problem that the rotating force of the brush must be obtained so as not to deform the food can and to obtain a sufficient cleaning effect.

A second invention of the apparatus for cleaning containers such as food cans of the present invention has been made to solve this problem. According to the first aspect of the present invention, the object to be washed is washed by the action of the washing water and the brush discharged from the drive shaft of the hydraulic motor. , That is, in the case of ordinary dirt, a good cleaning effect can be obtained by the first invention. However, if the dirt, for example, sauces, mayonnaise and other seasonings are mixed and the viscosity increases,
It is necessary to increase the rotational force of the brush and the amount of cleaning water sprayed on the object to be cleaned. However, as described above, since the rotational force of the brush that is excessively strong leads to deformation and breakage of the food can, it is necessary to set an appropriate rotational force of the brush for cleaning.

The water that has collided with the rotor blades is discharged from the discharge portion of the water guide wall to the lower case in the casing, and discharged through the hollow portion of the drive shaft. The inside of the lower casing of the casing is filled with water, and the head pressure of the casing pushes up the water in the hollow portion of the drive shaft. However, there is a limit to the amount of water discharged from the drive shaft, water cannot be contained in the lower case of the casing, and water returns to the upper case, and the returned water becomes the resistance of the rotor blades, and the torque of the hydraulic motor decreases. And the rotational force of the brush is reduced. To solve this problem, the water after contributing to rotate the rotor can be solved by filling only the lower case of the casing with water. This problem can be solved by providing a drain pipe on a side wall other than the side wall where the nozzle of the casing is provided to increase the amount of discharged water. However, as described above, since it is not too strong and it is necessary to set a rotational force suitable for washing, it is possible to easily set the rotational force by providing a plurality of drain pipes and adjusting the amount of drainage. Become.

The position of the drain pipe is closest to the water discharge section of the water guide wall, and the casing facing the side wall of the casing provided with the nozzle, in which the water discharged from the water discharge section of the guide wall forms a flow. If provided on the bottom surface by the side wall, water can be discharged effectively. The number and pipe diameters to be installed are arbitrary, but the area ratio with the side wall where the drainage pipe is provided is 1/10 to 1/1.
If the pipe diameter is 5, three pieces may be installed.

The drain pipe is extended, and one of the drain pipes is bent upward at the tip as described in Japanese Patent Application Laid-open No. Hei 8-24193, "Apparatus for cleaning tableware, etc." The cleaning water is sprayed on the object to be cleaned, so that the dirt is easily separated from the cleaning surface of the object to be cleaned, and the brush cleaning effect is promoted. If water is sprayed and a squeeze pipe is connected to the end of the extended drain pipe, not only the cleaning synergy between the cleaning water and the brush increases but also the cleaning effect is improved, and the rotational force of the hydraulic motor is adjusted. Can be performed simultaneously. At the tip of the extended drain pipe, a fixed amount of liquid detergent is sent from a small metering pump, mixed at the tip of the extended drain pipe, and sprayed on the object to be cleaned, thereby further improving the cleaning effect.

According to a third aspect of the present invention, there is provided a cleaning apparatus for containers such as cans according to the first or second aspect of the present invention. A resin-based base is provided with a rubber-based plate having a plurality of cutouts at a tip portion that comes into contact with a cleaning surface of an object to be cleaned, being fixed between the resin-based plate and the base. This is a cleaning device for containers such as cans.

The stain has a strong tackiness, such as a mixture of a seasoning such as a sauce and a stain such as an egg, which changes due to time and temperature, and when rice bran adheres to the washing surface. When a part is to be removed due to a tissue property, the connection with a part to be removed is strengthened. In the case of such a so-called "persistent dirt", dirt cannot be completely removed only by increasing the amount of cleaning water sprayed on the object to be cleaned and increasing the rotational force of the brush. In this case, it is necessary to consider the structure of the brush.

If the brush is implanted with a linear material on the substrate, if the brush is overcrowded, if the brush comes into contact with the cleaning surface of the object to be cleaned, the linear material loses its escape area, does not bend, and the cleaning effect is reduced. The flock material must be implanted in the substrate at intervals. A brush with a cleaning material planted therein has a limit in that the planted portion acts on the entire dirt, and requires more cleaning water. However, as described above, in order to remove `` persistent dirt '' in the case of dirt having strong adhesiveness, it is necessary to spread the flocked portion of the brush over the dirt in addition to promoting the washing water. is there.

The above problem can be solved by forming the brush base by forming the base of the brush into a corner or polygonal shape and attaching a rubber-based plate to the side surface of the base.

It is optional to attach the rubber-based plate to which side of the side surface of the brush base. However, if the number of the rubber-based plates to be attached is too large, the contact force increases.
In order to rotate this, it is necessary to consider the improvement of the torque of the hydraulic motor. Therefore, in practice, it may be attached to the two side surfaces of the rectangular base.

The material of the rubber plate may be the same as that of the linear material.

The shape of the notch at the tip of the rubber-based plate can be arbitrarily selected, such as V-cut, arc, line, or square. By providing the notch, the contact with the dirt surface is increased and decreased, and the dirt is easily separated from the cleaning surface.

A fourth aspect of the present invention in the apparatus for cleaning cans and other containers according to the present invention is that a hollow drive shaft (rotating shaft) constituting a hydraulic motor penetrates through a casing lid and is located above the surface of the casing lid. The pipe is connected to the hollow portion of the drive shaft at right angles to the drive shaft at a part of the position of the drive shaft, and the other end of the pipe is bent at 90 °, so that the shaft center of the pipe and the hollow hydraulic motor are formed. The drive shaft is rotatably connected so that the axes of the shafts coincide with each other, and the brush base connected to the hollow drive shaft has a plurality of water guide holes. is there.

The water that has collided with the rotary wings of the hydraulic motor by the nozzle is stored in the lower case of the casing from the water discharge portion of the water guide wall, and all or part of the water passes through the hollow portion of the drive shaft and extends in the axial direction. The water is discharged from the water guide hole of the brush base through a hollow portion of the drive shaft through a pipe connected to the drive shaft. Since the pipe and the hollow drive shaft are connected so that the drive shaft can rotate, the brush connected to the drive shaft can be rotated and washed by spraying cleaning water onto the dirt from the brush base. It becomes possible.

Since the washing water acts directly on the stain, it not only weakens the adhesion of the stain, but also plays a role of a lubricant, so that the contact of the flocked portion of the brush with the stain can be smoothly performed. Is possible.

In the cleaning apparatus for containers such as cans of the first invention,
A brush having a flexible and elastically deformable linear material such as silicon rubber planted on a base is rotated at a speed several times the rotational speed of the brush while rotating along the peripheral edge of the object to be cleaned. Since the object to be cleaned is washed together with the cleaning water discharged from the drive shaft, the lightened object to be cleaned can be effectively and continuously cleaned within a limited cleaning time without deformation. The brush rotates at a speed several times faster than that when the brush is connected to the drive shaft, and the wire is bent by using a brush in which a linear material such as silicone rubber having flexibility and elastic deformation is implanted. Since it does not need to be densely planted on the base because it comes into contact with the dirt, the dirt removed from the object to be cleaned does not adhere to the brush base due to the centrifugal force at the time of rotation of the brush, the flocking interval, and the action of washing water. .

In the apparatus for cleaning containers such as cans of the second invention,
By adjusting the plurality of drain pipes provided on the casing side wall, it is possible to easily set the rotational force of the brush according to the nature of the stain on the object to be cleaned.

In the apparatus for cleaning containers such as food cans of the third invention,
By attaching a rubber-based or resin-based plate, which has flexibility and is easily elastically deformed, to the base of the brush to form a brush, the effect of the brush can be exerted on the entire cleaning surface of the object to be cleaned.

In the apparatus for cleaning containers such as food cans of the fourth invention,
Since the brush used in the cleaning device for containers such as food cans of the present invention has a plurality of water guide holes in the base, the brush can rotate and wash the dirt while contacting the dirt while spraying cleaning water from the base of the brush. Since the cleaning water is pushed out in the brush rotating direction along the cleaning surface of the cleaning object by the rotating force of the brush, the flow of the cleaning water in the cleaning object becomes stronger,
The dirt removed by the brush is put on the flow of the cleaning water and can be discharged out of the object to be cleaned.

A pair of linear guides 20 is fixed to the lifting base 21. The rotation of the brush lifting / lowering motor 10 rotates the pinion gear 18 to move the rack gear 19 straight up and down, so that the brush cleaning unit 5 attached to the lifting / lowering base 21 can move up and down. Reference numeral 16 denotes a sensor detection plate which is attached to the lifting base 21. 1
Reference numeral 5 denotes a lifting / lowering stop position detection sensor, which is disposed for the upper limit and the lower limit. When the lifting / lowering base moves upward and the brush cleaning unit 5 comes to the cleaning position, the sensor for the upper limit stops the sensor detection plate 16. Is detected, the control signal is sent, the drive of the brush lifting / lowering motor 10 is stopped, the lifting / lowering base 21 is stopped, and the brush cleaning is performed. When the brush cleaning is completed, a cleaning completion timer signal is sent to the control system. Upon receiving the signal, the brush lifting / lowering motor 10 operates again in reverse to the upward movement, the lifting / lowering base 21 is lowered, and the lower limit sensor is detected by the detection plate 16.

The attach mate 38 is made of a resin such as polyethylene or polyacetal for preventing metal marks on the article 3 to be cleaned.

Since it is effective to wash the object 3 with a brush at a fixed position, a drive motor (not shown) for the chain conveyor 6 is also selected to have a built-in brake or a brake and a clutch.

The intermittent operation of the chain conveyor 6 is performed by attaching a detection plate to the attachment mate 38 or the shaft of the drive motor, providing a sensor at a position corresponding to the amount of movement of the attachment mate 38, and detecting the detection plate. What is necessary is just to stop the operation of the drive motor.

Is a square brush base, and a plurality of water guide holes 64 are provided so as not to interfere with the flocking rubber plate 65.
The flocked rubber plate 65 is provided with a plurality of V-shaped, long-hole, linear, square, and other cutouts 66 at its tip. The flocking rubber plate 65 is fixed between the coupling plate 67 and the base 63. FIG. 9 shows the cleaning of the inner surface of the object 3 to be cleaned.
Are attached to the brush base 63 for cleaning the bottom of the cleaning target 3 shown on the left side of the drive shaft and the brush base 63 for cleaning the upper part (opening side) of the right cleaning target 3. It is possible to act on the entire inner surface of the object 3 without cleaning.

The coupling plate 67 protrudes from the outer periphery of the base 63 by about 10 mm to regulate the bending of the flocking rubber plate 65 and to give the flocking rubber plate "stiffness".

The reason why the lengths of the base 63 and the rotation shaft 60 are unified is to stabilize the inertia of the load and reduce the vibration of the hydraulic motor 9.

A pipe 61 connects the hollow portion of the drive shaft 51 and the hollow portion of the rotation shaft 60, and is connected to the rotation shaft via a bearing 62 such as a carbon bush. The water guided from the lower case to the drive shaft passes through the rotation shaft 60, and the brush base water introduction hole 64 of the brush.
Then, water is sprayed on the object 3 to be cleaned. Rotating shaft 60
Is able to conduct water and rotate through the bearing,
Since the brush is connected to the pipe 61, the brush 3
It is possible to rotate while spraying water directly on.

According to the first aspect of the present invention, dirt on ordinary cans mainly composed of soup can be effectively removed by the action of a brush and washing water, and breakage and deformation of cans and metal marks can be prevented. . In addition, by using an elastic rubber-based or resin-based linear material for the brush, the brush can be used for a long time without "set", and can be washed hygienically.

In the second aspect of the present invention, there is no need to provide a mechanism for particularly reducing or increasing the rotational force of the brush, and by simply providing a plurality of drain pipes on the side wall of the hydraulic motor, a brush suitable for a linear shape can be easily obtained. The rotational force can be set, and at the same time, the effect of the cleaning water on the object to be cleaned can be improved.

According to the third aspect of the present invention, the brush is constituted by the angular or polygonal brush base and the rubber plate, so that the brush can be exerted on the entire surface of the cleaning surface of the object to be cleaned, and the adhesive strength is reduced. Effective cleaning is possible even for strong "stubborn" stains. Also, the brush eliminates the need for a flocking operation, and can greatly reduce both cost and production time.

According to the fourth aspect of the present invention, the drive shaft and the rotation shaft are communicated with each other by the water guide pipe, and the brush is provided with a plurality of water guide holes. It is possible to rotate, and the ability to remove dirt is greatly improved.

The means for horizontally moving the hydraulic motor is added to the means for raising and lowering the hydraulic motor according to the first to fourth aspects of the present invention, so that an effective continuous cleaning of a rectangular container such as a rice cooker for business use can be achieved. It becomes possible.
