The upper path portion of the second endless body 32 is fitted to the upper portion of the second guide body 31 so as to be slidable along the second guide body 31.

  The second support 33 is a horizontal plate 41 attached to the second endless body 32, and a protruding plate that integrally protrudes downward from the end of the horizontal plate 41 on the first support 13 side. A lower vertical plate portion 42. The vertical length of the lower vertical plate portion 42 is only required to be able to maintain the posture of the container W in the inclined posture, and is approximately half the width of the container W in this embodiment.

  Further, in the vicinity of the front side of the cleaning liquid ejecting means 3, a position above the horizontal plate portion 21 of the second support 33 is formed as a rotating roller, and an auxiliary for preventing the second endless body 32 from floating from the second guide body 31. A support 46 is provided.

  The container W introduced from the introduction unit 44 moves at least one of the first support 13 and the second support 33, that is, for example, at a position corresponding to the descending inclined part 15 of the first guide 11. Due to the lowering of the first support 13 and the approach of the second support 33 toward the first guide 11 at the position corresponding to the approaching inclined portion 35 of the second guide 31, a horizontal posture (upwardly facing) (Posture) is changed to an inclined posture (sideward posture) prepared for cleaning by the cleaning liquid ejecting means 3. That is, after the first support 13 is lowered by the vertical dimension of the lower vertical plate portion 42 of the second support 33 corresponding to the descending inclined portion 15, the second support 33 is moved toward the inclined inclined portion 15. Corresponding to 35, the container W approaches the first support 13 side by approximately half of the width of the horizontal plate portion 21 of the first support 13, so that the container W is inclined from the horizontal posture, for example, approximately 90 degrees. Change the posture to the inclined posture.

  When the cleaning liquid is sprayed from the cleaning nozzle 45 and the cleaning pipe 43 of the cleaning liquid spraying means 3 toward the opening W1 of the inclined container W, the contents in the container W (such as uneaten leftovers) are discharged. At the same time, the inner surface of the container W is cleaned. At this time, the container W is inclined by the upper vertical plate portion 22 of the first support 13 and the lower vertical plate portion 42 of the second support 33 while being placed on the horizontal plate portion 21 of the first support 13. Supported by posture.

  Next, when spray water is sprayed from the spray nozzle 47 of the water spraying means 4 toward the bottom surface of the inclined container W, the container W rotates about the upper vertical plate 22 as the center of rotation, and the container W starts from the inclined position. The posture is changed to a 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 an upper vertical plate portion 22 of the first support 13 and a third support 53 arranged in parallel with a third endless body 52 such as a chain. Are carried out to the next process (main cleaning device) by the carry-out conveyor 54. The third endless body 52 is fitted so that the upper path portion thereof is slidable along the third guide body 51 at the upper part of the third guide body 51.

  Further, as shown in FIG. 2 and the like, the cleaning device 1 includes a first guide wall 61 and a second guide wall 62. The first guide wall 61 regulates the movement of the container W toward the front side when the first support 13 is lowered, and guides the side edge of the container W toward the upper vertical plate portion 22 of the first support 13. . The second guide wall 62 guides the side edge of the container W toward the upper surface of the third support 53 by restricting the movement of the container W toward the front side when the posture is changed by the water ejecting means 4. Further, the cleaning device 1 includes a support guide 63 that prevents the second endless body 32 from being detached from the second guide body 31 at the bent position of the second guide body 31.

  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 in the horizontal posture with the opening W1 facing upward, and the horizontal plate portion 21 of the first support 13 is left in the horizontal posture. And it is mounted on the horizontal plate part 41 of the 2nd support body 33, and is conveyed in a conveyance direction.

  In the middle of the conveyance, the first support 13 is lowered by the length in the vertical direction of the lower vertical plate portion 42 of the second support 33 corresponding to the descending inclined portion 15, and then the second support 33 approaches. Corresponding to the inclined portion 35, the container W is moved from the horizontal position to the desired position by moving toward the upper side of the first guide body 11 by approximately half the width of the horizontal plate portion 21 of the first support 13. It becomes an inclined posture that is almost vertical.

  The container W in the inclined posture is placed on the horizontal plate portion 21 of the first support 13, and the side edge portion of the container W is supported by the upper vertical plate portion 22 of the first support 13. Since the bottom surface portion of the container W is supported by the lower vertical plate portion 42 of the second support 33, the desired inclination posture can be obtained without sliding with the portions other than the first support 13 and the second support 33. It is conveyed as it is.

  When the cleaning liquid is sprayed from the cleaning nozzle 45 and the cleaning pipe 43 toward the opening 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.

  Thereafter, when the spray water is sprayed from the spray nozzle 47 toward the bottom surface portion of the inclined container W, the container W is directed upward in the direction away from the lower vertical plate section 42 of the second support 33. And the container W is transported in the transport direction by the first support body 13 and the third support body 53 while maintaining the downward posture.

  Note that 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 47 and collides with the third support 53. 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 third support 53.

  The cleaning apparatus 1 includes a plurality of first supports 13 arranged in parallel with the first endless body 12 and a plurality of second supports 33 arranged in parallel with the second endless body 32, Since W is configured to change its posture from a horizontal posture to an inclined posture in the middle of conveyance by the lowering of the first support member 13 and the approach of the second support member 33 to the first guide member 11 side, the container W is set to approximately 90. Even if it is tilted to a degree, the container W in the tilted posture can be stably transported, and the container W can be transported appropriately, so that an appropriate cleaning operation can be performed.

  In addition, since the first support 13 is configured to lower one side in the transport direction of the container W by lowering the first support 13, hooks necessary for the configuration in which the one side in the transport direction of the container W is raised are attached to the first support 13. It does not need to be provided, and the containers W can be continuously put in contact with each other.

  In the above-described embodiment, a case has been described in which the transport unit 2 is applied to the cleaning device 1 that cleans a transported object such as the container W while the transported object is inclined while transporting the transported object. The present invention can also be applied to an article discharge device (such as a reversing device) that discharges the contents in the transported object or the placed object on the transported object while the transported object is transported while the transported object is inclined in the middle of the transport. In this case, the tilted posture of the transported object is not limited as long as the contents in the transported object or the placed object on the transported object can be discharged, and the opening of the transported object is steeply inclined from the gentle slope to the side. The range is set freely, and is not limited to a certain inclined posture.

  Further, the configuration is not limited to the configuration in which the conveyed object is changed in posture from the horizontal posture to the inclined posture by the lowering of the first support member 13 and the close movement of the second support member 33 to the first support member 13. Any configuration may be adopted in which the posture is changed to the inclined posture by the relative lowering of the support 13 with respect to the second support 33 and the relative approaching movement of the first support 13 with respect to the second support 33. For example, a configuration in which the first supporting body 13 is changed to an inclined posture by lowering the first supporting body 13 and approaching the second guiding body 31 to the first supporting body 13, rising of the second supporting body 33 and second guiding of the first supporting body 13 is performed. A configuration that changes to an inclined posture by approaching the body 31 side, a configuration that changes to an inclined posture by raising the second support 33 and approaching the first guide body 11 to the second support 33 may be used. Further, when the relative lowering of the first support 13 with respect to the second support 33 is caused by the lowering of the first support 13 and the rising of the second support 33, or the second support 33 of the first support 13. The relative approaching movement relative to may be due to the approaching movement of both supports 13,33.

  Further, the lower vertical plate portion 42 of the second support 33 is not simply projected downward from the horizontal plate portion 41, but is adapted to the inclination of the bottom surface portion of the container W in the inclined posture. If the bottom portion is supported in a planar shape, the container W can be transported more stably.

  That is, although not shown, the second support 33 may have a protruding plate portion that protrudes downward from the horizontal plate portion 41 and contacts the bottom surface portion of the inclined container W to support the bottom surface portion. Good.
