Next, usage examples and operations of the above-described cleaning apparatus according to the present invention will be described.
A large number of used box-shaped containers c are prepared in the vicinity of the cleaning device. Here, the box-shaped container c is a resin-made commercial product that is used to store mandarin oranges harvested at a farm or the like and transport them to a storage location. The size of the box-shaped container c is, for example, about 20 kg and is integrally formed. As shown in FIG. 3, the bottom surface c1 and the peripheral wall portion c2 are provided, the upper surface is opened, the outer surface and the inner surface of the bottom surface c1 are smooth, and the two pairs of flat surfaces facing the peripheral wall portion c2 are slightly formed. It is a quadrangular tube that is inclined so as to spread upward, and is formed so as to surround the entire periphery in the lateral direction and the reinforcing protrusion h1 formed long on the outer surface of the peripheral wall portion c2 in the height direction. A plurality of slits j having a protrusion h2 and a smooth inner surface of the peripheral wall portion c2 and having a long shape in the height direction are juxtaposed in the horizontal direction at each planar portion of the peripheral wall portion c2. It has been.

  Prior to cleaning, the electric system such as the nozzle operation controller 46A is turned on and the tap water is led to the water inlet of the electromagnetic on-off valve 44, and tap water is led to the conduit 48 when necessary.

  Thereafter, the operator opens the opening / closing cover 1e completely to open the front surface of the casing 1 greatly. Under this condition, a single box-shaped container c is held by hand and the horizontal orientation is such that the top opening of the box-shaped container c faces the rear side f1, and the box-shaped container c is inserted into the back side of the casing 1. The peripheral wall portion c2 positioned below the second roll-shaped brush 7 is connected to the first roll-shaped brushes 4, 4 and the second while the second roll-shaped brush 7 is positioned inside the box-shaped container c. It is located between the roll-shaped brushes 7. At this time, since the second roll-shaped brush 7 moves about several cm to 10 cm upward in conjunction with the opening / closing cover 1e, the peripheral wall portion c2 includes the first roll-shaped brushes 4, 4 and the second roll-shaped brush 7. It will be smoothly inserted between.

  Next, the operator closes the opening / closing cover 1e. Thereby, the box-shaped container c is in a state where the outer surface of the bottom surface c1 is pushed to the back side by the brush rubbing means 38, and the inner surface of the bottom surface c1 is pressed by the brush bristles 7b at the tip of the second roll-shaped brush 7. Since the second roll-shaped brush 7 descends in conjunction with the opening / closing cover 1e, the peripheral wall portion c2 of the box-shaped container c is securely sandwiched between the first roll-shaped brushes 4 and 4 and the second roll-shaped brush 7. It becomes.

Thereafter, the operator turns on and operates the cleaning start switch of the operation panel 46, whereby the following processing is automatically performed.
That is, the tap water is led to the conduit 48 and water is sprinkled from the water sprinkling hole g of the water supply pipe 47, and the electromagnetic on-off valve 44 is opened by the operation of the timer 45, and the first water supply pipe 43a. For example, pressure water is supplied for about 5 seconds only, and water is ejected vigorously from the three corresponding water jet nozzles 41.

  On the other hand, the electric motor 16A is actuated to rotate the driving sprocket 24 to the positive side f2 shown in FIG. 7, and in conjunction with this, the first roll brushes 4 and 4 and the second roll brush 7 are shown in FIG. As shown, it rotates to the positive side f2, and by the rotation of these brushes 4 and 7, the peripheral wall portion c2 of the box-shaped container c is moved from the first roll-shaped brushes 4 and 4 and the second roll-shaped brush 7 to the bristles 4b, A feeding force is applied via 7b, whereby the box-shaped container c is rotated about a line in the front-rear direction, and the rotation direction is counterclockwise when viewed from the front. The three water injection nozzles 41 corresponding to the first water supply pipes 23a inject water vigorously while the box-shaped container c rotates, for example, approximately once.

  Therefore, the first roll-shaped brushes 4 and 4 and the second roll-shaped brush 7 are effectively rubbed with the brush bristles 4b and 7b at the same time in the presence of water by rubbing the outer surface and the inner surface of the peripheral wall portion c2. The second roll-shaped brush 7 is rubbed against the inner surface of the bottom surface c1 with the brush bristles 7b at the tip of the second roll-shaped brush 7 so as to wash off dirt adhering thereto. Further, the third roll-shaped brush 38 smoothly slides the rotational displacement of the box-shaped container c, and the brush bristles 38a rub the entire bottom surface c1 in the presence of water to wash away dirt adhering thereto.

  At this time, since the brush hairs 4b and 7b on the outer peripheral surface of each of the first roll-shaped brushes 4 and 4 and the second roll-shaped brush 7 are of the same size, the peripheral wall portion c2 is in the height direction. The first and second roll brushes 4 and 4 and the second roll brush 7 are in contact with the first roll brushes 4 and 4 and the second roll brush 7 in a generally uniform manner, and the outer peripheral surfaces of the first roll brushes 4 and 4 and the second roll brush 7 are peripheral wall portions. Since it is inclined in the front-rear direction corresponding to the inclination in the height direction of c2, the bottom surface c1 is maintained in a vertical posture during the rotation of the box-shaped container c. By these actions, the box-shaped container c is stably rotated around the front-rear line while being sandwiched between the first roll-shaped brushes 4, 4 and the second roll-shaped brush 7, and during this rotation, The first roll-shaped brushes 4, 4, the second roll-shaped brush 7 and the third roll-shaped brush 38 rub against the entire surface of the box-shaped container c evenly, and effectively remove the dirt attached thereto.

  When such a process is performed for approximately 5 seconds, the electromagnetic on / off valve 44 is opened / closed by the timer 45, the water supply to the first water supply pipe 23a is shut off, and the water from the corresponding water injection nozzle 41 is supplied. The injection is stopped and the supply of water to the second water supply pipe 23b is started, and water is injected from the three water injection nozzles 41 forming a group corresponding thereto for about 5 seconds, for example. For example, the box-shaped container c rotates approximately once.

  At this time, since the water injection nozzles 41 of each group corresponding to the first water supply pipe 23a and the second water supply pipe 23b have different water injection directions for each group, the counterclockwise direction f4 in FIG. 9 of the protrusion h1. The water sprayed from the water spray nozzle 41 vigorously collides with the one side m1 which is the front side of the ridge h2 and the front and rear side surfaces of the protrusion h2, and the dirt such as earth and sand adhering thereto is washed away.

  During this cleaning, the first roll brushes 4 and 4 are rotated faster than the second roll brush 7, so when the first roll brushes 4 and 4 and the second roll brush 7 are viewed in detail, FIG. As shown in FIG. 8, the bristles 4b are bent. If the bristle 4b is bent in this manner, a situation may occur in which the tip of the bristle 4b does not enter the part of the protrusion h1 at the front side of the box-shaped container rotation direction, and the dirt at the part may not be removed. .

  In order to avoid such a fear, when the box-shaped container c rotates, for example, approximately twice, the electric motor 16A can switch the rotation direction, whereby the driving sprocket 24 is rotated to the reverse side f3 and interlocked therewith. Then, the first roll brushes 4 and 4 and the second roll brush 7 rotate to the reverse side f3 as shown in FIG.

  Thereby, the first roll brushes 4 and 4 and the second roll brush 7 act symmetrically with respect to the action when they are rotated to the positive side f2, and the box-shaped container c removes the casing 1. When viewed from the front, it is rotated clockwise around the front-rear line. As a result, when the electric motor 16A rotates to the positive side, the bristles 4b bend and enter the portion p1 that could not be cleaned without entering, and the cleaning of the portion p1 is performed accurately.

  When water injection for about 5 seconds, for example, by the three water injection nozzles 41 forming a group corresponding to the second water supply pipe 23b is completed, the electromagnetic open / close valve 44 is opened and closed by the timer 45, and the second water supply pipe 23b is moved to the second water supply pipe 23b. Water supply from the corresponding water injection nozzle 41 is stopped and water supply to the third water supply pipe 23c is started, and three water injection nozzles 41 forming a group corresponding to this are started. From about 5 seconds, for example. During the injection, the box-shaped container c makes, for example, one rotation.

  Then, when water injection for about 5 seconds, for example, by the three water injection nozzles 41 forming a group corresponding to the third water supply pipe 23c is completed, the electromagnetic open / close valve 44 is opened and closed by the timer 45, and the third water supply pipe The water supply to 23c is interrupted, the water injection from the corresponding water injection nozzle 41 is stopped, and the water supply to the fourth water supply pipe 23d is started, and three water injections forming a group corresponding to this are started. For example, water is sprayed from the nozzle 41 for about 5 seconds. During the injection, the box-shaped container c makes one rotation.

  At this time, since the water injection nozzles 41 of each group corresponding to the third water supply pipe 23c and the fourth water supply pipe 23d have different water injection directions for each group, the clockwise direction f5 in FIG. 9 of the protrusion h1. The water jetted from the water jet nozzle 41 vigorously collides with the front side m2 and the front and rear sides of the ridge h2, and the dirt such as earth and sand adhering thereto is washed away.

  Thus, when the box-shaped container c is rotated, for example, approximately four times around the line in the front-rear direction, the box-shaped container is in a state where the entire surface including the ridges has been effectively cleaned. Water supply to the pipes 23a, 23b, 23c, 23d, 47 is shut off, and the operation of the electric motor 16A is stopped.

  After confirming this stop, the operator fully opens the opening / closing cover 1e, and under this state, the washed box-shaped container c is taken out from the inside of the casing 1 to the outside. At this time, since the second roll-shaped brush 7 is moved upward in conjunction with the opening / closing cover 1e, the peripheral wall portion c2 sandwiched between the first roll-shaped brushes 4, 4 and the second roll-shaped brush 7 is released, The brushes 4 and 7 are smoothly taken out.

  After taking out the cleaned box-shaped container c, the box-shaped container c to be cleaned next is inserted into the casing 1 in the same manner as before, and thereafter the same processing and operation as before are repeated.
