  An embodiment according to a cleaning apparatus of the present invention will be described with reference to the drawings.

  1 to 3, reference numeral 1 denotes a cleaning device. The cleaning device 1 is a container W that is a plurality of substantially dish-shaped objects having a substantially rectangular opening W1 on an upper surface, for example, a top-opening lunch. This is a continuous container cleaning device that continuously transports boxes in the transport direction, changes the posture of the container W from a horizontal posture to an inclined posture in the middle of the conveyance, and performs cleaning by spraying a cleaning liquid such as cleaning water, for example, underwashing. .

  The horizontal position of the container W is such that the opening W1 faces upward (upward position), and the inclined position of the container W is such that the opening W1 faces sideways in the transport direction (sideward position). ) And the inclination angle is set to a value of about 90 degrees.

  As shown in FIGS. 4 to 8, the cleaning device 1 transports a container W in the transport direction and changes the posture of the container W from a horizontal posture to a substantially vertical inclined posture during the transport. 2 and by discharging the cleaning liquid toward the opening W1 of the container W in an inclined posture being conveyed by the conveying means 2, the contents in the container W, for example, uneaten leftover food, etc. are discharged at the same time. The cleaning liquid injection means 3 for cleaning the inner surface of the container W and the attitude of the container W from the inclined attitude by injecting the spray water as the injection liquid toward the bottom surface portion of the inclined container W being conveyed by the conveying means 2 Water injection means 4 for changing the opening W1 to a downward orientation in which the opening W1 faces downward, that is, an inverted horizontal posture, is provided.

  The transport means 2 includes a guide body 6 such as a rail that is long in the transport direction, an endless body 7 such as an endless chain that moves along the guide body 6 while being guided by the guide body 6, and an endless body 7. And a plurality of substantially plate-like transport bodies (bendable plates) 8 that are transported in parallel with each other along the transport direction and transport the container W mounted thereon. Further, the transport means 2 is disposed along the plurality of transport bodies 8 and supports the side edges of the containers W so that the containers W do not fall from the transport bodies 8 to the side. And a guide rail 10 which is long in the conveying direction for supporting the rotating plate portion 14 of the conveying body 8 from below and rotating the rotating plate portion 14 in the vertical direction. Yes. As shown in FIG. 2, the fixed guide body 9 includes a first guide portion 16, a second guide portion 17, and a third guide portion 18 that are fixed to the mounting frame 20.

  The endless body 7 is stretched over a plurality of rotating bodies 11 and rotated by power from driving means (not shown) such as a motor. The upper path portion of the endless body 7 is fitted on the upper portion of the guide body 6 so as to be slidable along the guide body 6.

  Each conveyance body 8 is comprised by the board member which can be bent, for example in the width direction intermediate part. Each transport body 8 has a fixed plate portion 13 fixed to the endless body 7 in a horizontal state. At one end portion along the conveying direction of the fixed plate portion 13, a rotating plate portion 14 that is turned into a horizontal state and an upright state by rotation is provided so as to be rotatable in the vertical direction, and along the conveying direction of the fixed plate portion 13 The other end is a free end 15. A fixed guide body 9 is disposed near the free end 15 of the fixed plate portion 13, and a guide rail 10 that is in sliding contact with the lower surface of the rotating plate portion 14 is disposed below the rotating plate portion 14.

  Then, the container W in a horizontal posture placed on the fixed plate portion 13 and the rotating plate portion 14 that are both in a horizontal state is rotated upward, that is, transported with respect to the fixed plate portion 13. While being guided by the second guide portion 17 of the fixed guide body 9 so as not to slide down from the side of the fixed plate portion 13 as the body 8 is bent, the body 8 is rotated by about 90 degrees to be in a substantially vertical inclination posture. .

  The container W in this inclined posture is supported at the side edge of the container W by the third guide portion 18 of the fixed guide body 9 and the free end portion 15 of the fixed plate portion 13 and at the bottom of the container W. Is supported by the rotating plate portion 14 in an upright state, and the conveyance direction is maintained in an inclined posture while being in sliding contact with the third guide portion 18 of the fixed guide body 9 by the movement of the conveyance body 8 based on the rotation of the endless body 7. Placed and conveyed.

  When the cleaning liquid is ejected from the cleaning nozzle 21 and the cleaning pipe 22 of the cleaning liquid ejecting means 3 toward the opening W1 of the inclined container W being transported by the transport body 8, the inside of the tilted container W The contents (such as leftover food) are discharged and the inner surface of the container W is cleaned. At this time, the container W in the inclined posture is supported by the third guide portion 18 and the fixed plate portion 13 of the fixed guide body 9 and the bottom portion of the container W in the standing state. Since it is supported by the moving plate part 14, it does not fall down due to the spray of the cleaning liquid.

  Moreover, the rotation board part 14 should just be the height which can support the container W of the inclination attitude | position so that it may not fall down. Further, the third guide portion 18 may be of a height that can support the side edge of the container W so that the container W in the inclined posture does not slide and fall down from the fixed plate portion 13. The contents are easily discharged from W.

  Next, when the spray water is sprayed from the spray nozzle 23 of the water spray means 4 toward the upper part of the bottom surface of the inclined container W, the container W rotates around the third guide portion 18 of the fixed guide body 9. As a result, the posture is changed from a tilted posture to a downward posture (inverted horizontal posture) with the opening W1 facing downward. The container W in the inverted horizontal posture is placed and conveyed in the inverted horizontal posture by the endless pair of conveying chains 25 that are spaced apart from each other, and then transferred to the carry-out conveyor 26 such as a mesh conveyor and the next process (main cleaning device) ).

  The cleaning device 1 regulates the movement of the container W toward the front side when the posture is changed by the water jetting means 4 and guides the side edge of the container W toward the one transport chain 25. It has 30.

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

  The substantially dish-like container W containing contents such as uneaten leftovers remains in a horizontal posture in which the opening W1 faces upward, and the fixed plate portion 13 and the horizontal rotating plate portion 14 remain in the horizontal posture. Is transported in the transport direction.

  As shown in FIG. 5, when the rotating plate portion 14 of the transport body 8 rotates upward with respect to the fixed plate portion 13 while being in sliding contact with the guide rail 10, the side edge of the container W is fixed to the container W. The guide body 9 is rotated approximately 90 degrees along the second guide portion 17 so as to descend to a position in sliding contact with the third guide portion 18, so that the inclined posture is substantially vertical on the fixed plate portion 13.

  And the container W which became the inclination attitude | position near substantially perpendicular | vertical has the side edge part of the container W supported by the free end part 15 of the 3rd guide part 18 and the fixed board part 13, and the bottom face part of the container W Is supported by the rotating plate portion 14 in an upright state, and is placed in an inclined posture while being in sliding contact with the third guide portion 18 of the fixed guide body 9 by the movement of the transport body 8 based on the rotation of the endless body 7. Be transported.

  As shown in FIG. 6, when the cleaning liquid is sprayed from the cleaning nozzle 21 and the cleaning pipe 22 toward the opening W1 of the inclined container W, the contents in the container W are discharged at the same time. The inner surface is cleaned.

  In addition, since the container W in the inclined posture is supported by the third guide portion 18 and the rotating plate portion 14, the inclined posture can be stably used even if the spraying force of the cleaning liquid is increased.

  Thereafter, when the spray water is sprayed from the spray nozzle 23 toward the bottom surface of the inclined container W, the container W is centered on the third guide part 18 in a direction away from the rotating plate part 14 in the standing state. And the container W is transported in the transport direction with the inverted horizontal 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 23 and collides with the transport chain 25. For this reason, even if the contents that have not been discharged due to the ejection of the cleaning liquid remain, the contents are completely discharged from the container W due to the collision between the container W and the transport chain 25.

  According to such a cleaning apparatus 1, the horizontal container W is rotated by approximately 90 degrees while being guided by the fixed guide body 9 as the rotating plate portion 14 rotates upward with respect to the fixed plate portion 13. Then, the container W in the inclined position is supported with the side edges of the container W supported by the fixed guide body 9 and the fixed plate 13 and the bottom surface of the container W is turned upright. Since it is configured to be transported while being supported by the plate portion 14, the inclination angle of the container W can be set to a value of approximately 90 degrees, and thus the interior of the container W that is nearly vertical with the cleaning liquid from the cleaning liquid ejecting means 3 can be set. Can be washed reliably.

  Further, since the side edge portion of the container W on the fixed guide body 9 side is lowered by the upward rotation of the rotation plate portion 14 with respect to the fixed plate portion 13, it is necessary when the side edge portion of the container W is raised. It is not necessary to provide a simple hook, and the containers W can be continuously put in contact with each other.

Na us, but Figures show, near the bending start of the carrier 8, i.e. at the upper turning near the beginning of the rotating plate 14, container presser portions on the fixing plate portion 13 of the downstream side of the vessel W W You may arrange | position the rollable auxiliary roll which can be rotated which prevents the float of the downstream of the conveyance direction.
