  Each transport body 23 has a fixed plate portion 26 which is a fixed portion fixed to the endless body 22 in a horizontal state. A first projecting plate portion 27 that is a first projecting portion that supports the side edge portion of the inclined container W is integrally provided in one end portion along the conveying direction of the fixed plate portion 26 so as to project upward. It has been. The length dimension of the first protruding plate portion 27 in the vertical direction is only required to support the side edge of the inclined container W, and is approximately half the height dimension of the container W in this embodiment. A second projecting plate portion 28 that is a second projecting portion that supports the bottom surface portion of the inclined container W is provided integrally with the other end portion of the fixed plate portion 26 along the conveying direction so as to project upward. It has been. The length dimension of the second protruding plate portion 28 in the vertical direction is only required to hold the container W in an inclined posture, and is approximately half the width dimension of the container W in this embodiment. The second protruding plate portion 28 is slightly inclined toward the side opposite to the first protruding plate portion 27 side.

  The posture change guide means 4 is constituted by, for example, a rollover guide 31 and a guide plate 32 that are fixedly provided. As shown in FIG. 5, the rollover guide 31 includes a horizontal plane portion 33 for receiving the container W in a horizontal posture from the horizontal plate portion 14 of the carrier 13 of the horizontal transfer means 2, and an inclined transfer means from the end of the horizontal plane portion 33. And an inclined surface portion 34 integrally projecting obliquely downward toward the third side. The angle formed by the horizontal surface portion 33 and the inclined surface portion 34 is, for example, about 45 degrees. The guide plate 32 is arranged in a vertical direction along the conveying direction and is positioned so as to be opposed to the inclined surface portion 34 of the roll guide 31 and guides the side edge portion of the container W to the first projecting plate portion 27. 35. The guide surface portion 35 is located on the same plane as the first projecting plate portion 27 of the transport body 23 that moves together with the endless body 22 of the inclined transport means 3, and a position in the vicinity of the lower portion of the guide surface portion 35 is the first position of the transport body 23. The protruding plate part 27 moves. Further, a feed brush 40 which is a feed means for feeding the container W onto the horizontal surface portion 33 of the rollover guide 31 is rotatably provided above the conveyance end portion of the horizontal conveyance means 2. The feed brush 40 is rotated by power from drive means (not shown) such as a motor.

  And the container W from the horizontal plate part 14 of the conveyance body 13 of the horizontal conveyance means 2 is pushed straight out in the conveyance direction by the feed brush 40, so that the entire container W is placed on the horizontal plane part 33 of the rollover guide 31. After the transfer, the container W slides sideways on the inclined surface portion 34 of the roll-over guide 31 by its own weight, and then the guide surface portion 35 of the guide plate 32 conveys the inclined conveying means 3 with a substantially U-shaped cross section. The container W is guided toward the inside of the body 23, and as a result, the container W has a desired inclined posture of about 90 degrees on the carrier 23 and is conveyed while being held in the inclined posture by the carrier 23.

  When the cleaning liquid is sprayed from the cleaning nozzle 41 and the cleaning pipe 42 of the cleaning liquid spraying means 6 toward the opening W1 of the inclined container W held and transported by the transport body 23, the contents in the container W ( The inner surface of the container W is cleaned at the same time as uneaten leftover food or the like is discharged. At this time, the side edge portion of the container W in the inclined posture is supported by the first projecting plate portion 27 of the transport body 23, and the bottom surface portion of the container W in the tilted posture is supported by the second projecting plate portion 28 of the transport body 23. Since it is supported, the container W does not fall down due to the spray of the cleaning liquid.

  Next, when spray water is sprayed from the spray nozzle 43 of the water spray means 7 toward the upper part of the bottom surface of the inclined container W, the container W rotates around the first projecting plate portion 27 of the transport body 23. And the posture is changed from the inclined posture to the downward posture (inverted horizontal posture) in which the opening W1 faces downward. At this time, the container W is supported in an inverted horizontal posture by the first projecting plate portion 27 of the transport body 23 and a support body 46 arranged in parallel with an endless body 45 such as a chain, and thereafter, a carry-out conveyor 47 such as a mesh conveyor. Is taken out to the next process (main cleaning device).

  Further, as shown in FIG. 2 and the like, the cleaning apparatus 1 includes a first guide wall 51 and a second guide wall 52. The first guide wall 51 prevents the container W from falling by restricting the movement of the container W placed on the transport body 13 of the horizontal transport means 2 to the near side, that is, the direction orthogonal to the transport direction. The second guide wall 52 guides the side edge of the container W toward the upper surface of the support 46 by restricting the movement of the container W toward the front side when the posture is changed by the water ejecting means 7.

  Next, the operation and the like of the cleaning device 1 will be described.

  After the lid is removed, the container W containing contents such as uneaten leftover food remains on the transport body 13 of the horizontal transport means 2 in the horizontal position with the opening W1 facing upward. And is transported in the transport direction.

  At the conveyance end position of the horizontal conveyance means 2, the container W is pushed straight out in the conveyance direction by the feed brush 40, and approximately half of the width direction of the container W is transferred onto the horizontal plane portion 33 of the rollover guide 31. The container W riding on the horizontal surface portion 33 of the rollover guide 31 rolls over to the labor side by its own weight, slides down on the inclined surface portion 34 of the rollover guide 31, and then tilts and conveys on the guide surface portion 35 of the guide plate 32. 3 is guided toward the inside of the carrier 23 having a substantially U-shaped cross section. Thus, the container W is in an inclined posture and is conveyed while being held in a desired inclined posture by the first protruding plate portion 27 and the second protruding plate portion 28 of the transfer body 23 having a substantially U-shaped cross section.

  The feeding brush 40 completely pushes out the container W from the conveyance end position of the horizontal conveying means 2 while keeping the horizontal state, so that the container W is inclined obliquely forward from the middle of the transfer of the container W to the rollover guide 31. It is possible to prevent sliding down into the transport body 23.

  When the cleaning liquid is sprayed from the cleaning nozzle 41 and the cleaning pipe 42 toward the opening W1 of the inclined container W, the contents in the container W are discharged and at the same time the inner surface of the container W is cleaned. .

  Since the inclined container W is held by the first projecting plate portion 27 and the second projecting plate portion 28 of the transport body 13, the container W is increased even if the cleaning liquid is increased by increasing the spraying force of the cleaning liquid. Is not in contact with parts other than the transport body 13 and is stably transported and cleaned.

  Thereafter, when the spray water is sprayed from the spray nozzle 43 toward the bottom surface of the inclined container W, the container W is centered on the first projecting plate 27 in the direction away from the second projecting plate 28. The container W is rotated in the inverted horizontal posture, which is a downward orientation, and then the container W is conveyed in the conveying direction by the first projecting plate portion 27 and the support body 46 in the inverted horizontal posture.

  When the posture of the container W is changed to the downward posture, the container W is vigorously rotated by the force received from the spray water from the spray nozzle 43 and collides with the support 46. For this reason, even if the contents that were not discharged by the jet of the cleaning liquid remain, the contents are completely discharged from the container W due to the collision between the container W and the support 46.

  Thus, according to the cleaning apparatus 1, the inclined conveying means 3 that conveys the container W in the inclined posture while being held in the inclined posture, and the inclined carrier means 3 while changing the posture of the container W from the horizontal posture to the inclined posture. Since the posture changing guide means 4 for guiding and the cleaning liquid ejecting means 6 for injecting the cleaning liquid toward the container W in the inclined attitude being conveyed by the inclined conveying means 3, the injection pressure of the cleaning liquid is sufficiently increased. However, the container W in an inclined posture does not stagnate due to the spray of the cleaning liquid, and the container W can be stably transported, and the container W is not damaged by rubbing or the like, and an appropriate cleaning operation can be performed. .

  In addition, the 2nd protrusion board part 28 of the conveyance body 23 of the inclination conveyance means 3 makes the bottom surface part of the container W of an inclination attitude | position, planar by making it incline according to the inclination of the bottom face part of the container W of an inclination attitude | position. You may make it support this bottom face part in contact with.

  In addition, a cleaning nozzle that cleans the bottom surface of the container W may be provided above the container W that has been inverted by the water jetting unit 7.
