  However, in the configuration in which one side edge of the object to be slid down by the inclined posture is supported by the fixed stopper so as to be slidable as in the conventional conveying device, the inclined posture of the conveyed object As the ratio increases, the ratio of the object to be transported shifts from the support by the transport endless belt and the inclined endless belt to the support by the fixed stopper, and comes into sliding contact with the fixed stopper. Instability increases, and there is a possibility that it cannot be transported after a certain tilting posture.

  The present invention has been made in view of such a point, and an object of the present invention is to provide a transport apparatus that can stably transport a transported object in any inclined posture.

  The transport apparatus according to claim 1 is a transport apparatus that transports a transported object in a transport direction and changes the transported object from a horizontal posture to an inclined posture in the middle of the transport. A plurality of transport bodies that are arranged in parallel along the transport direction and transport the article to be transported, and each transport body is fixed to the endless body in a horizontal state; A rotating part that is pivotably provided and changes the posture of the conveyed object from a horizontal position to an inclined position by rotating downward, and is fixed to the rotating part, and the conveyed object is fixed when the rotating part is rotated downward. It has a support part which supports a to-be-conveyed object so that it may not slide down from on the rotation part.

  The transport device according to claim 2 is the transport device according to claim 1, wherein the support portion of the transport body rises from the rotating portion, and a rising portion whose rising dimension is larger than a height dimension of the object to be transported, And a protruding portion protruding from the upper end portion of the rising portion toward the rotating portion.

  According to the first aspect of the present invention, the support portion of the transport body supports the transported object so that the transported object does not slide off from the rotating portion when the rotating portion rotates downward. Therefore, the object to be conveyed can be stably conveyed without being in sliding contact with the fixed stopper.

  According to the second aspect of the present invention, the support portion has a rising portion whose rising dimension is larger than the height dimension of the conveyed object, and a protruding portion protruding from the upper end portion of the rising portion toward the rotating portion. Therefore, it is possible to reliably prevent the transported object from slipping down.

  An embodiment 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 transports a container W, which is a plurality of objects to be transported having a substantially rectangular opening W1 on the upper surface, for example, a lunch box having an upper surface opening. This is a continuous container cleaning device that continuously transports the container W during the transport, changes the posture of the container W from a horizontal posture to an inclined posture, and performs cleaning, for example, washing by spraying a cleaning liquid such as cleaning water.

  The cleaning apparatus 1 transports the container W in the transport direction, and in the middle of the transport, the position of the container W is an upward posture with the opening W1 facing upward, that is, a side where the opening W1 faces the transport direction side. In this container W, the cleaning liquid is ejected toward the opening W1 of the container W in the side-oriented position that is being transferred by the transfer means 2 and the transfer means 2 that is a transfer device that changes to the orientation, that is, the inclined position. The cleaning liquid ejecting means 3 for cleaning the inner surface of the container W at the same time as discharging the contents of the food, such as leftover food, and the bottom surface of the container W in the lateral orientation being transported by the transport means 2 Water injection means 4 is provided for changing the posture of the container W from a lateral orientation to a downward orientation in which the opening W1 faces downward, that is, an inverted horizontal posture, by ejecting spray water that is liquid.

  As shown in FIGS. 4 to 8, the transport means 2 is a guide body 6 such as a rail that is long in the transport direction, and an endless shape that moves along the guide body 6 while being guided by the guide body 6. An endless body 7 such as a chain, and a plurality of substantially plate-shaped transport bodies (plates) 8 that are juxtaposed on the endless body 7 along the longitudinal direction of the endless body 7 and that place and transport the container W in the transport direction; It has.

  The endless body 7 is stretched over a plurality of rotating bodies 9 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 transport body 8 has a fixed plate portion 11 that is a fixed portion fixed to the endless body 7 in a horizontal state. At the end of the fixed plate portion 11 along the conveying direction, a rotating plate portion 12 that is a rotating portion that changes the posture of the container W from a horizontal posture to an inclined posture by rotating downward is provided to be rotatable in the vertical direction. It has been.

  Further, the length dimension of the rotating plate portion 12 is set so that the container W in the inclined posture can maintain the state, and is preferably longer than half of the width dimension of the container W.

  At the end of the rotating plate 12 along the conveying direction, when the rotating plate 12 is rotated downward, that is, while the horizontal rotating plate 12 rotates approximately 90 degrees downward, the container W A support plate (projection piece) 13, which is a support portion having a substantially L-shaped cross section for supporting the container W, is fixed so that the container W does not slide off due to its own weight. The support plate 13 rises from the end along the transport direction of the rotating plate 12 with the fixed plate 11 and the rotating plate 12 positioned horizontally (see FIG. 4). A rising portion 14 slightly larger than the height of the container W and a protruding portion 15 slightly protruding horizontally from the upper end portion of the rising portion 14 toward the rotating plate portion 12 side.

  The projecting portion 15 is so projected that the edge of the container W does not slide out of the rising portion 14 when the container W is in an inclined posture.

Each transport body 8 includes a guide rail portion 17 that supports the lower surface of the rotating plate portion 12 and rotates the rotating plate portion 12. The guide rail portion 17 has a first rail 18 on the conveyance start end side and a second rail 19 on the conveyance end side.

  The container W introduced from the introduction part 21 is first placed on the fixed plate part 11 and the rotating plate part 12 both in a horizontal state in a horizontal posture with the opening W1 facing upward. It is placed and transported in the transport direction by the transport body 8 in a horizontal posture. Next, when the rotating plate portion 12 of the transport body 8 is rotated downward with respect to the fixed plate portion 11, the container W is inclined in preparation for cleaning by the cleaning liquid ejecting means 3 from the horizontal posture (upward posture) during the transport. The posture is changed to a posture (a lateral posture), for example, an inclined posture of approximately 90 degrees. When the rotating plate 12 is rotated downward, the support plate 13 of the transport body 8 supports the container W so that the container W does not slide down from the rotating plate 12 to the side in the conveying direction due to its own weight. To do.

  When the cleaning liquid is sprayed from the cleaning nozzle 25 and the cleaning pipe 26 of the cleaning liquid spraying means 3 into the opening W1 of the container W in the inclined posture, the contents in the container W (such as uneaten leftovers). Simultaneously with the discharge, the inner surface of the container W is cleaned. At this time, the container W is supported in an inclined posture by the rotating plate portion 12 and the support plate portion 13.

  Next, when the spray water is sprayed from the spray nozzle 27 of the water spray means 4 toward the bottom surface of the inclined container W, the container W protrudes upward from the rising portion 14 of the support plate 13. The posture is changed from the inclined posture to the downward posture (inverted horizontal posture) in which the opening W1 faces downward by rotating about the protruding portion 15 in the state. At this time, the container W is supported in an inverted horizontal posture by the protruding portion 15 of the support plate portion 13 and the support body 32 arranged in parallel with the endless body 31 such as a chain, and thereafter, in the carry-out conveyor 34 such as a mesh conveyor. It is carried out to the next process (main cleaning device). The endless body 31 is fitted so that the upper path portion thereof is slidable along the guide body 35 at the upper portion of the guide body 35.

  Further, as shown in FIG. 2 and the like, the cleaning apparatus 1 includes a first guide wall 22 and a second guide wall 39. The first guide wall 22 maintains the horizontal state and covers the sides while the rotating plate portion 12 of the transport body 8 is rotating. The second guide wall 39 regulates the movement of the container W toward the front side when the posture is changed by the water ejecting means 4 and guides the side edge of the container W toward the upper surface of the support 32.

  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 is placed on the transport body 8 in the horizontal posture in which the opening portion W1 faces upward. It is transported in the transport direction.

  In the middle of the conveyance, the rotating plate 12 rotates downward in accordance with the shape of the guide rail 17 so that the container W touches other than the conveyance body 8 while being placed on the conveyance body 8. Instead, the horizontal posture is changed to a desired inclined posture close to the vertical.

  When the cleaning liquid is directly sprayed from the cleaning nozzle 25 and the cleaning pipe 26 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. The At this time, even if the cleaning liquid is strongly sprayed toward the opening of the container W, the rotating plate 12 supports the bottom surface of the container W and the support plate 13 supports the edge of the container W. Therefore, cleaning and transportation are performed without rattling.

  Further, since the protruding portion 15 is a protruding portion so that the edge portion of the container W in the inclined posture does not slide off from the rising portion 14, the contents in the container W are discharged without being disturbed. .

  Thereafter, when the spray water is sprayed from the spray nozzle 27 toward the bottom surface of the inclined container W, the container W rotates about the protruding portion 15 in the direction away from the rotating plate 12. The container W is transported in the transport direction by the support plate portion 13 and the support body 32 while maintaining 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 27 and collides with the support 32. 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 32.

  As described above, according to the cleaning device 1, the support plate portion 13 of the transport body 8 supports the container W so that the container W does not slide off from the rotation plate portion 12 when the rotation plate portion 12 rotates downward. Therefore, unlike the conventional case, the container W does not come into sliding contact with the fixed stopper, that is, the container W is not rubbed with another member in the middle of conveyance, and the container W can be stably conveyed, and the container due to rubbing or the like. W damage or the like can also be prevented.

  The rising dimension 14 is larger than the height dimension of the container W, and has a substantially L-shaped cross section having a protruding part 15 protruding from the upper end of the rising part 14 toward the rotating plate 12 side. The support plate portion 13 can reliably prevent the container W from slipping down.

  Further, since the side of the container W in the conveyance direction is lowered by the downward rotation of the rotation plate 12, the container W can be conveyed without slipping and staying on the conveyance body 8. It is not necessary to provide a hook required when the side portion is raised, 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.
