Description

  The present invention relates to a distribution vehicle.

  Traditionally, in restaurants such as hotel restaurants, room service, hospital meals, employee cafeterias, student cafeterias, etc., it is easy to batch the prepared foods at the lunch center in a remote location. In many cases, the refrigerators are arranged on trays and stored in refrigerators in each facility until refrigeration time. At the time of serving, a warm / cold distribution vehicle (distribution vehicle) equipped with a refrigeration room and a refrigeration room is used to reheat or refrigerate the food that has been kept cold and transport it to a food supplier such as a guest. Are known.

  This type of allocation vehicle includes a storage chamber that can be opened and closed by a door, and a plurality of upper and lower partition members that partition the storage chamber into a refrigerator compartment and a warm storage compartment, and between partition members adjacent in the vertical direction. By inserting the tray into the formed tray passage, the tray is disposed so as to straddle the refrigerator compartment and the warm compartment.

Further, in Patent Documents 1 and 2 below, among the partition members adjacent in the vertical direction forming the tray passage, the partition members positioned below are provided at the front end portion and the rear end portion along the tray transport direction. The structure provided with the cam and the cam member provided in the center part along a conveyance direction is disclosed.
Specifically, the cams shown in Patent Documents 1 and 2 are supported so as to be swingable around the support shaft along the vertical direction, and are biased upward by a spring to be applied to the upper surface of the partition member. On the other hand, it is configured to appear and disappear. Further, the cam member is urged upward by a spring, and is configured to be able to protrude and retract with respect to the upper surface of the partition member by moving up and down.

  According to this configuration, when the tray is transported into the tray path, the cam or cam member is pushed downward by the tray to allow the tray to be transported in the tray path. On the other hand, when the tray is stored, the cam and the cam member are elastically restored to the protruding state protruding from the upper surface of the partition member and come into contact with the outer surface of the tray, so that the tray can be stored after partitioning the warm room and the cold room. It is said that.

Japanese Patent No. 2967226 Japanese Patent No. 4822466

However, in the above-described prior art, there is room for improvement with respect to stable operation of the cam and the cam member.
Specifically, in the above-described prior art, the cam and the cam member are configured to be able to appear and retract by swinging or vertically moving with respect to the upper surface of the partition member. Therefore, when the cam and the cam member are changed from the depressed state in which the cam and the cam member are pushed into the upper surface of the partition member to the protruding state described above, the cam and the cam member may contact the inner surface of the partition member and may not return to the protruding state. is there. In this case, the storage room cannot be reliably partitioned into the warm room and the cold room, and there is a concern that the desired atmosphere cannot be maintained between the warm room and the cold room.

Further, since the cam and the cam member are pushed in a direction (downward) different from the tray conveying direction, there is a possibility that the protruding state cannot be smoothly changed to the depressed state.
Furthermore, since cams and cam members having different configurations are used in the front end portion and rear end portion along the tray conveyance direction, and the central portion, there is also a problem that the manufacturing cost increases.

  Accordingly, the present invention has been made in consideration of the above-described circumstances, and can stably partition the storage chamber by the first chamber and the second chamber when the tray is transported, and can stably operate the rotating body. An object of the present invention is to provide a distribution vehicle that can be made to operate.

(1) The partition member that is provided in a plurality of stages in the vertical direction and that stores the tray and a partition member that partitions the storage chamber into a first chamber and a second chamber, and is adjacent to the vertical direction In the allocation vehicle in which the tray is inserted into a tray passage formed between the tray chamber and the tray is stored in the storage chamber in a state of straddling the first chamber and the second chamber, the partition adjacent in the vertical direction Among the members, one of the partition members is configured such that when the tray enters the tray path, the tray can come into contact with an outer peripheral surface and around the support shaft along the tray conveyance direction. A polygonal rotating body that is rotatably supported is provided, and the rotating body rotates around the support shaft, whereby a corner portion protrudes from the partition member into the tray path, and The corner is in the tray passage It has a configuration which varies between a retracted state, the retracted to the inside of the one of the partition member with.

With this configuration, when the tray is transported in the tray path, the rotating body is pushed in along the transport direction of the tray by coming into contact with the outer peripheral surface of the rotating body in the protruding state. Accordingly, the rotating body rotates around the support shaft and changes to the retracted state, whereby the tray can be conveyed into the tray path. And after a tray passes a rotary body, a rotary body contacts a tray from the back of a conveyance direction by changing to a protrusion state again. Accordingly, the tray is stored in the storage chamber in a state of straddling the first chamber and the second chamber.
Here, since the rotating body that changes between the protruding state and the retracted state is provided, when the cam or cam member is configured to be swingable or vertically movable with respect to the partition member as in the prior art, In comparison, the rotating body can be operated stably. As a result, the first chamber and the second chamber can be reliably partitioned by the rotating body, and mixing of cold air and warm air between them is suppressed, and the storage chamber is maintained in a desired atmosphere. It becomes easy.
Further, since the rotating body is rotatable along the tray conveying direction, the rotating body is pushed along the rotating direction when the tray is conveyed. Therefore, it is possible to smoothly change from the protruding state to the retracted state.
Further, by adopting a rotating body that can rotate around the support shaft, for example, when storing two trays side by side along the transport direction, the tray operates regardless of the transport direction. Therefore, common parts can be realized at the front end portion and rear end portion in the transport direction, and the central portion, and cost reduction can be realized.

(2) The arrangement vehicle of (1) may include a transition unit that changes the rotating body from the retracted state to the protruding state.
According to this structure, since the transition means for changing the rotating body from the retracted state to the protruding state is provided, the rotating body can be reliably changed to the protruding state after passing through the tray. Accordingly, the tray can be stably supported, and the first chamber and the second chamber can be reliably partitioned by the rotating body.

(3) In the allocation vehicle of (2), the transition means may be a biasing member that biases the rotating body around the support shaft toward the protruding state.
According to this configuration, the transition means is configured by the urging member, so that the configuration can be simplified and the rotating body can be reliably changed to the protruding state.

(4) In the arrangement wheel of (2), the transition means can move the weight member along with the rotation of the weight member and the rotating body, and guide the weight member below the corner portion. And a weight guide to be provided.
According to this configuration, when the rotating body is in the retracted state, the weight member is guided below the corner portion by the weight guide, so that the rotating body is reliably changed to the protruding state and the rotating body is held in the protruding state. can do.

  According to the distribution vehicle of the present invention, the storage chamber can be reliably partitioned by the first chamber and the second chamber during the conveyance of the tray, and the rotating body can be stably operated.

The upper end surfaces of the central partition member 31c and the lower partition member 31b and the upper surface of the connecting block 24 described above are flush with each other, and the support surface supports the lower surface of the tray 50 when the tray 50 is transported or stored. Is functioning as

  A first slit 32 opened downward is formed in the lower end surface of the central partition member 31c and the upper partition member 31a along the width direction. In the central partition member 31c and the upper partition member 31a, two first movable partition pieces 33 that can be moved in and out of the partition member 31 through the first slits 32 are arranged in parallel along the width direction.

The 1st movable partition piece 33 is a plate-shaped thing extended along the width direction, and is made into the inverted trapezoid shape which tapers toward the inner side of the width direction as it goes below seeing from the front-back direction. Specifically, the first movable partitioning piece 33 has a flat surface 33a positioned below, and an inclined surface 33b that is inclined outward in the width direction as it goes upward from both ends in the width direction of the flat surface 33a. doing.
Each first movable partition piece 33 is in a state of projecting downward from the first slit 32 by its own weight. Thereby, the flat surface 33a of each 1st movable partition piece 33 adjoins or contact | abuts the upper end surface of the center partition member 31c or the lower stage partition member 31b located below. The first movable partition piece 33 may be urged downward by an urging means (not shown).

  Further, the flat surface 33a and the inclined surface 33b of the first movable partitioning piece 33 have a shape corresponding to the inner surface shape of the tray 50 (see FIG. 2B) along the short side direction, and the tray 50 is in the storage chamber 13. It is possible to come into contact with the inner surface of the tray 50 in a state of being housed in the tray. Specifically, the flat surface 33 a comes into contact with the upper surface of the flat plate portion 51 of the tray 50, and both inclined surfaces 33 b come into contact with the inner surfaces of the surrounding edges 52 facing each other in the short side direction of the tray 50.

A plurality of (for example, three) second slits 34 opening upward are formed on the upper end surfaces of the central partition member 31c and the lower partition member 31b. Each of the second slits 34 is a portion located between the first movable partition piece 33 and the first movable partition piece 33 in the width direction, that is, both ends in the width direction of the central partition member 31c and the lower partition member 31b. It is formed in the part and the center part.
The central partition member 31 c and the lower partition member 31 b are provided with a second movable partition piece 41 that can be moved in and out of the partition member 31 through the second slit 34 for each second slit 34.

The second movable partition piece 41 includes a triangular plate-shaped rotating body 43 that is rotatably supported by the support shaft 42, and an urging member (transition means) 44 that urges the rotating body 43 upward. Yes.
The support shaft 42 extends along the front-rear direction, and both end portions thereof are supported by the central partition member 31c and the lower partition member 31b, respectively.

  The rotating body 43 rotates around the support shaft 42 along the conveyance direction (width direction) of the tray 50 in the tray path R, so that any one of the corner portions 43a is positioned upward, and the corner portion 43a. It changes with the retracted state (refer FIG.6 (c)) to which the connection part 43b which connects between is located upwards. Specifically, when the rotating body 43 is in the protruding state, the corner 43a protrudes above the upper end surfaces of the central partition member 31c and the lower partition member 31b through the second slit 34 and is positioned in the tray passage R. Yes. On the other hand, when the rotating body 43 is in the retracted state, the corner 43a is retracted inward from the upper end surfaces of the central partition member 31c and the lower partition member 31b, and the tray passage R is opened.

Is approaching or abutting on the outer peripheral surface from below. The urging member 44 is bent and deformed in the vertical direction following the rotation of the rotating body 43. Specifically, when the rotating body 43 changes (rotates) from the protruding state to the retracted state, the biasing member 44 bends in a direction away from the support shaft 42 while resisting the restoring force. Deform. On the other hand, when the rotating body 43 changes (rotates) from the retracted state to the protruding state, the urging member 44 is restored and deformed toward the direction in which the other end approaches the support shaft 42.

(Function)
Next, the operation of this embodiment will be described. In the following description, the initial state is when the rotating body 43 of the second movable partition piece 41 is in the protruding state. FIG. 6 is a cross-sectional view corresponding to FIG. 5 and is an explanatory diagram for explaining a method of transporting the tray 50.
First, when the tray 50 is carried into the distribution vehicle 1, first, for example, the door 15 on one side in the width direction is opened, and the storage chamber 13 is opened. Then, as shown in FIG. 6A, the tray 50 is inserted into the tray path R from the opening on one side in the width direction in the storage chamber 13. In this case, the tray 50 is inserted into the tray path R with the short side direction of the tray 50 aligned with the width direction.

  Then, as shown in FIG. 6 (b), the tray 50 first has a portion located on the front side in the conveying direction in the surrounding edge 52 and the flange portion 53 (hereinafter simply referred to as the front end portion of the tray 50). Of the two movable partition pieces 41, the second movable partition piece 41 abuts on one side in the width direction. Specifically, the front end portion of the tray 50 comes into contact with the outer peripheral surface of the rotator 43 from the rear in the transport direction, and pushes the rotator 43 along the front in the transport direction. As a result, the rotating body 43 starts to rotate around the support shaft 42 along the conveying direction, and among the corner portions 43a of the rotating body 43, the corner portion 43a protruding from the partition member 31 enters the second slit 34. At the same time, the other end of the urging member 44 is bent and deformed so as to be separated from the support shaft 42. Thereafter, when the front end portion of the tray 50 passes through the second slit 34, the corner portion 43 a of the rotating body 43 is in a retracted state positioned on the inner side of the upper end surface of the partition member 31.

When the tray 50 is further pushed in along the transport direction, the front end portion of the tray 50 comes into contact with the inclined surface 33b of the first movable partition piece 33 from the rear in the transport direction. Thereafter, as shown in FIG. 6C, the front end portion of the tray 50 is slidably contacted on the inclined surface 33b and the flat surface 33a, so that the first movable partitioning piece 33 faces the direction (upward) against its own weight. And pushed. Thereby, the tray passage R is opened.
As a result, the lower surface of the tray 50 is in sliding contact with the upper end surface of the partition member 31 positioned below among the partition members 31 adjacent in the vertical direction, and the upper end edge slides on the flat surface 33 a of the first movable partition piece 33. In the contact state, it is conveyed in the tray path R. When the tray 50 is moving on the second movable partition piece 41, the second slit 34 is closed by the tray 50, so that the rotation of the second movable partition piece 41 to the protruding state is restricted, The second movable partition piece 41 is held in the retracted state.

Thereafter, when the front end portion of the tray 50 passes through the first movable partition piece 33, the first movable partition piece 33 moves downward by its own weight and enters the inside of the tray 50, whereby the first movable partition piece. The flat surface 33 a and the inclined surface 33 b of 33 are in contact with the inner surface of the tray 50. Moreover, the outer surface of the enclosure edge 52 is the outer periphery of the 2nd movable partition piece 41 (rotary body 43) arrange | positioned among the some 2nd movable partition pieces 41 among the front-end parts of the tray 50 among the some 2nd movable partition pieces 41. Abuts on the surface from the rear in the transport direction.
Further, when the rear end portion of the tray 50 passes through the second movable partition piece 41, the pressure on the rotating body 43 is released, and the second movable partition piece 41 (rotating body 43) located on one side in the width direction is attached. The force member 44 rotates around the support shaft 42 along the conveying direction by the restoring force of the force member 44. Accordingly, the rotating body 43 rotates from the retracted state toward the protruding state, so that the outer peripheral surface of the rotating body 43 comes into contact with the rear end portion of the tray 50 (the outer surface of the enclosure edge 52) from the rear in the transport direction.

  As a result, in the tray path R, the tray 50 is sandwiched between the upper end surface of the partition member 31 positioned below and among the movable partition pieces 33 and 41 among the partition members 31 adjacent in the vertical direction. The Accordingly, the tray 50 is stored in the storage chamber 13 in a state of straddling between the warm room and the cold room.

When two trays 50 are stored side by side in the width direction, the second tray 50 is placed in the tray passage R from the other opening in the width direction in the storage chamber 13 by the same method as described above. This can be done by inserting.
Further, after the first tray 50 is further pushed in from the opening on one side in the width direction toward the other side in the width direction, the second tray 50 is further inserted from the opening on one side in the width direction. It doesn't matter. In this case, the conveyance method to the other side of the width direction of the 1st tray 50 can be performed by the method similar to the method mentioned above. Note that the second tray 50 may be inserted so that the first tray 50 is pushed toward the other side in the width direction.

  On the other hand, when the tray 50 stored in the storage chamber 13 is carried out, for example, one side in the width direction of the storage chamber 13 is opened with the door 15 on one side in the width direction opened and the storage chamber 13 opened. Pull out the tray 50 from the opening. Then, the first movable partition piece 33 is pushed up by the front end portion of the tray 50 so as to resist its own weight, and the rotating body 43 of the second movable partition piece 41 rotates around the support shaft 42 along the transport direction and retracts. By changing to the state, the inside of the tray passage R is opened. Thereby, the tray 50 can be pulled out smoothly from the inside of the tray path R. After the tray 50 is pulled out, the first movable partition piece 33 is restored by its own weight and approaches or comes into contact with the upper end surface of the partition member 31, while the second movable partition piece 41 protrudes by the restoring force of the biasing member 44. Rotate towards state.

As described above, in the present embodiment, the corner portion 43a is rotated by being pressed along the conveyance direction of the tray 50, and the corner portion 43a projects from the partition member 31 into the tray path R, and the corner portion 43a. Is configured to include a second movable partition piece 41 (rotating body 43) that changes between a retracted state in which the tray path R retracts to the inside of the partition member 31.
According to this configuration, since the rotating body 43 is configured to be rotatable around the support shaft 42, the cam and the cam member can be swung or moved up and down with respect to the partition member 31 as in the past. The rotating body 43 can be operated stably as compared with the case where it does. Thereby, it becomes possible to partition a warm room and a refrigerator compartment reliably by the rotary body 43, suppress mixing of warm air and cold air between both, and maintain the storage chamber 13 in a desired atmosphere. It becomes easy.

Further, since the rotating body 43 is rotatable along the transport direction of the tray 50, the rotating body 43 is pushed along the rotating direction when the tray 50 is transported. Therefore, it is possible to smoothly change from the protruding state to the retracted state.
Further, by employing the rotating body 43 that can rotate around the support shaft 42, for example, when storing two trays 50 side by side along the transport direction, the tray 50 operates regardless of the transport direction. Therefore, common parts can be realized at the front end portion and the rear end portion in the transport direction (width direction), and the central portion, and the cost can be reduced.

Moreover, since the transition means (urging member 44) for changing the rotating body 43 from the retracted state to the protruding state is provided, the rotating body 43 can be reliably changed to the protruding state after passing the tray 50. Accordingly, the tray 50 can be stably supported, and the warm room and the refrigerator room can be reliably partitioned by the rotating body 43.
Furthermore, since the transition means is configured by the biasing member 44, the rotating body 43 can be reliably changed to the protruding state after the configuration is simplified.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. In the following description, the same configuration as that of the first embodiment described above is assigned the same configuration, and the description is omitted. The present embodiment is different from the first embodiment described above in that the weight member 111 is used as the transition means of the rotating body 43. FIG. 7 is a cross-sectional view corresponding to FIG. 5 in the second embodiment.

The weight guide 112 is a partition wall that surrounds the center of the rotating body 102. Specifically, the weight guide 112 has a triangular shape connecting the bulging portions 102c (center portions) of the rotating body 102, and connects the guide corner portion 112a holding the weight member 111 and the guide corner portion 112a. In addition, a guide connecting portion 112b that guides the weight member 111 toward the guide corner portion 112a is provided. That is, the corner portion 102a of the rotating body 102 and the guide corner portion 112a of the weight guide 112 face each other across the center of the rotating body 102, and when the rotating body 102 is in the protruding state, the weight member 111 is the corner portion. It is held below 102a.

FIG. 8 is a cross-sectional view corresponding to FIG. 7 and is an explanatory diagram for explaining a method of transporting the tray 50.
In the second movable partition piece 101 of this embodiment, as shown in FIGS. 8A and 8B, when the tray 50 is transported in the tray path R, the rotating body 43 is transported in the transport direction by the front end portion of the tray 50. Is rotated around the support shaft 42, and the rotating body 102 changes from the protruding state to the retracted state. Further, the weight member 111 in the rotating body 102 moves on the weight guide 112 from the guide corner portion 112a toward the guide connecting portion 112b as the rotating body 102 rotates. And as shown in FIG.8 (c), when the rotary body 102 exists in a retracted state, the weight member 111 will be located on the guide connection part 112b.

  Then, as shown in FIG. 7, when the rear end portion of the tray 50 passes through the second movable partition piece 101, the weight member 111 is guided from the guide connecting portion 112b toward the guide corner portion 112a. 102 rotates toward the protruding state. The weight member 111 is held in the guide corner portion 112a, so that the rotating body 102 is held in a protruding state, and the outer peripheral surface of the rotating body 102 is the rear end portion of the tray 50 (the outer surface of the surrounding edge 52). It contacts from the back of the conveyance direction.

  Therefore, according to the present embodiment, the same effects as those of the first embodiment described above can be obtained, and the weight member 111 is guided below the corner portion 102a by the weight guide 112 when the rotating body 102 is in the retracted state. Therefore, the rotating body 102 can be reliably changed to the protruding state, and the rotating body 102 can be held in the protruding state.

  The technical scope of the present invention is not limited to the above-described embodiments, and includes those in which various modifications are made to the above-described embodiments without departing from the spirit of the present invention. In other words, the configuration described in the above-described embodiment is merely an example, and can be changed as appropriate.

  For example, in the above-described embodiment, the case where the rotating bodies 43 and 102 have a triangular shape has been described. However, by forming the rotators 43 and 102 in a triangular shape, the protrusion height from the partition member 31 can be secured, the tray 50 can be stably supported, and the warm room and the refrigeration room can be connected to the rotators 43, 102. It is preferable in that it can be surely partitioned by 102.

  Further, in the above-described embodiment, the first movable partition piece 33 is provided in the partition member 31 positioned above among the partition members 31 adjacent in the vertical direction, and the second movable partition piece 41 is disposed in the partition member 31 positioned below. In contrast to this, the second movable partition piece 41 may be provided on the partition member 31 located on the upper side, and the first movable partition piece 33 may be provided on the partition member 31 located on the lower side. .
