  As shown in FIGS. 1, 5, and 8, a rail portion 22 projects from the center of the transport surface 3 of the order transport path 1 a in the left-right width direction over substantially the entire length in the longitudinal direction. Specifically, the transport surface 3 is made of a metal plate material such as aluminum or stainless steel, and the rail portion 22 is formed by pressing the plate material, so that the rail portion 22 is formed. On the lower surface side of the plate material, there is formed a U-shaped conveying groove 23 that is downwardly opened and opens downward. The left and right sides of the conveying groove 23 are formed on the side wall 23a.

  Next, the traveling body 7 will be described. As shown in FIGS. 5 and 7, the traveling body 7 includes a carriage unit 24 that travels on the conveying surface 3, and a plurality of food and beverage dishes that are attached to the carriage unit 24 from above and on which ordered foods and beverages are placed. 6 and a tray portion 25 for mounting 6. On the upper surface of the tray portion 25, a placement recess 25a for placing the food and drink dish 6 is formed. By placing a plurality of food and drink dishes 6 on the placement recess 25a, food and drinks are provided. The dish 6 can be held so as not to drop out of the tray portion 25.

  As shown in FIG. 3, the carriage portion 24 is a base portion formed in a square shape so as to stably support the loads of the plurality of food dishes 6 placed on the tray portion 25. 26 and a pair of roller brackets 27 attached to two locations of the front end portion and the rear end portion of the base portion 26. These roller brackets 27 are formed in a downward U-shape as shown in FIG. A first magnetic body 18 as a connecting means in the present invention protrudes downward from substantially the center in the left-right width direction between the front portion and the rear portion of the carriage portion 24.

  On both outer surfaces of the roller bracket 27, a load roller 28 as a roller in the present invention for allowing the traveling body 7 to travel on the transport surface 3 can be rotated by a pivot that faces the left-right width direction of the roller bracket 27. It is pivotally supported. A pair of sub brackets 30 are attached between the load rollers 28 in the roller bracket 27. A load roller 28 is also pivotally supported at the end of the sub bracket 30 on the side closer to the center in the lateral direction of the roller bracket 27 so as to be rotatable in the vertical direction. That is, the load roller 28 is pivotally supported by each roller bracket 27.

  Between the left and right end portions of the roller bracket 27, a pair of front and rear track rollers 29 is pivotally supported by two pivots that are directed in the left-right direction and are directed in the vertical direction. The track rollers 29 are pivotally supported so as to be line-symmetric in the left-right width direction at both left and right side portions in a space surrounded by the roller bracket 27.

  Further, a support roller 31 as a rolling element in the present invention is pivotally supported at the end of the sub bracket 30 on the outer side in the lateral width direction of the roller bracket 27 so as to be rotatable in the vertical direction. The upper portions of the support rollers 31 protrude above the roller bracket 27 through slit holes 27a formed through the roller bracket 27 in the vertical direction.

  As shown in FIG. 5, the left-right width dimension between the track rollers 29 is slightly longer than the left-right width dimension of the rail portion 22 of the transport surface 3, and the traveling body 7 is arranged on the transport surface 3. As a result, the track rollers 29 are arranged close to the left and right of the rail portion 22 at the front end portion and the rear end portion of the traveling body 7.

  As described above, the track rollers 29 are arranged in the left-right width direction of the rail portion 22 at the front end portion and the rear end portion of the traveling body 7, thereby defining a traveling path on the transport surface 3 of the traveling body 7. In addition, since the track roller 29 abuts on the rail portion 22, it is possible to prevent the traveling body 7 from swinging in the left-right width direction.

  A circular through hole 27b is formed in a substantially central portion in the left-right width direction and the front-rear width direction of the roller bracket 27, and the first magnetic body 18 is fitted into the through hole 27b. Yes. Since the upper end portion of each support roller 31 comes into contact with the lower surface of the base portion 26 by fitting the first magnetic body 18 into the through hole 27 b, each roller bracket 27 is supported by the support roller 31 on the food and drink dish 6. While supporting the load, the first magnetic body 18 is pivotally supported about the first magnetic body 18 with the first magnetic body 18 as a pivot that faces in the vertical direction.

  As shown in FIGS. 4, 5, and 7, the belt bracket 17 includes a horizontal piece 32 a disposed at the front portion, a horizontal piece 32 b disposed at the rear portion, and an attachment disposed below the horizontal pieces 32 a and 32 b. And a piece 32c. A pivot shaft (not shown) facing the vertical direction (not shown) is provided at the upper end of the mounting piece 32c, and a center roller 39 is pivotally supported on the pivot shaft.

  Further, both the rear end portion of the horizontal piece 32a and the front end portion of the horizontal piece 32b are rotatable between a center roller 39 and the upper end portion of the attachment piece 32c on a pivot (not shown) provided at the upper end portion of the attachment piece 32c. It is pivotally supported. Therefore, the horizontal pieces 32 a and 32 b can swing in the left-right width direction of the belt bracket 17 with the same axis as the center roller 39.

  Furthermore, a slide hole 32d is formed through the front end portion of the horizontal piece 32a and the rear end portion of the horizontal piece 32b so as to face in the left-right width direction of the belt bracket 17 in the vertical direction. The transport bracket 20 is disposed above the slide holes 32d.

  A second magnetic body 19 serving as a second connecting means in the present invention is disposed at a substantially central portion of the transport bracket 20 in plan view. As shown in FIGS. 4 and 7, the space between the second magnetic bodies 19, 19 is formed to have a front-rear width dimension that is substantially the same as the front-rear width dimension between the first magnetic bodies 18, 18 in the traveling body 7. . For this reason, the traveling body 7 and the belt bracket 17 are arranged so that the first magnetic body 18 and the second magnetic body 19 are opposed to each other at two places in the front and rear with respect to the traveling direction of the traveling body 7 with the conveying surface 3 interposed therebetween. The first magnetic body 18 and the second magnetic body 19 are driven and connected by a magnetic force generated between them.

  One of the first magnetic body 18 and the second magnetic body 19 may be composed of a ferromagnetic metal, the other may be composed of a permanent magnet or the like, or both may be composed of a permanent magnet or the like. May be.

  In addition, the second magnetic body 19 is connected by a slide pin 40 which faces the conveyance bracket 20 in the vertical direction, and the lower end portion of the slide pin 40 is inserted into the slide hole 32d. For this reason, each conveyance bracket 20 is pivotally supported by the slide pin 40 which faces the vertical direction before and after the belt bracket 17 with respect to the horizontal pieces 32a and 32b, and is slidable in the left-right width direction. Is attached.

  As shown in FIGS. 4, 5, and 6, a traveling roller 41 as a rotating body in the present invention for traveling the belt bracket 17 toward the driving direction of the driving belt 15 on both outer side surfaces of the transport bracket 20. Is pivotally supported by a pivot that faces in the horizontal direction. The upper ends of the traveling rollers 41 are in contact with traveling surfaces 43 that are lower surfaces of the conveying surface 3 formed on the left and right sides of the conveying groove 23. For this reason, the belt bracket 17 is driven by the driving belt 15 so as to travel on the traveling surface 43 by the traveling roller 41, and between the first magnetic body 18 and the second magnetic body 19. The second magnetic body 19 is prevented from floating toward the first magnetic body 18 by the generated magnetic force.

  Further, a pair of front and rear guide rollers 42 are pivotally supported on the upper surface of the transport bracket 20 so as to be rotatable in the horizontal direction and horizontally. The width dimension between the outer end portions in the left-right width direction of these guide rollers 42 is formed to be shorter than the width dimension between both side walls 23a, 23a of the conveying groove 23, and is the upper end portion of the belt bracket 17. The second magnetic body 19, the center roller 39, and the guide roller 42 are arranged in the conveyance groove 23 described above.

  For this reason, the second magnetic body 19 moves in the transport groove 23 over the substantially entire length of the order transport path 1a when the drive belt 15 is driven. The diameter of the center roller 39 is substantially the same as the width between the outer ends of the guide roller 42 in the left-right width direction.

  In this way, when the drive belt 15 is driven by configuring the order conveyance path 1a and the traveling body 7, as shown in FIG. 7, the traveling body 7 and the belt bracket 17 are located at the first and second magnetic bodies at the two front and rear positions. 18 and the second magnetic body 19 are driven and connected, so that the force for transporting the traveling body 7 required for the drive connection between the first magnetic body 18 and the second magnetic body 19 can be distributed to the front and rear two locations. Even if the magnetic force generated between the body 18 and the second magnetic body 19 is small, the traveling body 7 can be transported.

  Further, by reducing the magnetic force generated between the first magnetic body 18 and the second magnetic body 19, the force that the second magnetic body 19 lifts toward the first magnetic body 18 can be suppressed, and the traveling rollers 41 and the traveling can be performed. The frictional force generated with the surface 43 can also be reduced.

  Next, the operation of the traveling body 7 traveling on the conveyance surface 3 and the belt bracket 17 traveling on the traveling surface 43 by driving the drive belt 15 will be described. First, as shown in FIGS. 3 and 5, the second magnetic body 19 moves in the driving direction of the driving belt 15 in the conveyance groove 23. At this time, the vibration of the drive belt 15 is transmitted to the second magnetic body 19 via the belt bracket 17, but the center roller 39 and the guide roller 42 abut against the left and right side walls 23 a in the conveyance groove 23. Therefore, the second magnetic body 19 is prevented from swinging in the left-right width direction, and the substantially central position in the transport groove 23 is maintained.

  The vibration of the drive belt 15 via the horizontal pieces 32 a and 32 b to the conveying bracket 20 is transmitted in the horizontal width direction of the horizontal pieces 32 a and 32 b and the slide hole 32 d with respect to the slide pin 40. It is alleviated by swinging in the direction.

  In addition, the traveling body 7 is opposed to each second magnetic body 19 that moves in a state where each first magnetic body 18 moves in the conveyance groove 23 with the center roller 39 restrained from swinging in the left-right width direction. Since it is arranged, it can travel straight on the conveyance surface 3.

  As shown in FIGS. 8 and 9, when the belt bracket 17 enters the first corner 10a by driving the driving belt 15, both the conveying brackets 20 at the front end portion and the rear end portion of the belt bracket 17 are moved to the first corner. It rotates horizontally with respect to the belt bracket 17 along the curved shape of 10a, and the frictional force that each traveling roller 41 receives from the traveling surface 43 is reduced.

  At the same time, the width between the second magnetic bodies 19 and 19 is always equal to the width between the first magnetic bodies 18 and 18 by swinging the horizontal pieces 32a and 32b toward the inner peripheral side of the first corner 10. Accordingly, it is possible to prevent the drive connection from being released due to the separation of the first magnetic body 18 and the second magnetic body 19.

  At the same time, the belt bracket 17 can bend smoothly even when the first corner 10 has a relatively sharp curve by swinging the horizontal pieces 32a and 32b toward the inner peripheral side of the first corner 10. Yes. At this time, the horizontal pieces 32a and 32b swing within a range in which the driving connection between the second magnetic bodies 19 and the first magnetic bodies 18 is not released.

  Further, the belt bracket 17 further reduces the frictional force that each traveling roller 41 receives from the traveling surface 43 by sliding both the conveying brackets 20 toward the outside of the first corner 10a along the slide hole 32d. . For this reason, when the belt bracket 17 travels through the first corner 10a, the friction force generated between the travel roller 41 and the travel surface 43 is suppressed, and the belt bracket 17 can travel smoothly through the first corner 10a. It has become.

  Note that the amount of movement of the slide movement toward the outside of the first corner 10 a of the transport bracket 20 is determined by the guide roller 42 disposed in the transport groove 23 being in contact with the side wall 23 a of the transport groove 23. It is regulated within a range where the contact of the roller 41 with the running surface 43 is not released. Further, the transport bracket 20 always travels by rotating around the second magnetic body 19 while the two guide rollers 42 contact the side wall 23a of the transport groove 23 formed along the transport surface 3 in the front-rear direction. Since the roller 41 can be directed in the traveling direction of the belt bracket 17, smooth traveling of the traveling roller 41 on the traveling surface 43 is realized.

  On the other hand, the traveling body 7 having the first magnetic body 18 that is drivingly connected to the second magnetic body 19 by a magnetic force extends from the roller brackets 27 on the front side in the traveling direction of the traveling body 7 to the rail portion 22 of the first corner 10a. By starting to rotate along the shape, both roller brackets 27 rotate around the first magnetic body 18 and of the two front and rear track rollers 29 arranged on the inner peripheral side of the first corner 10a. The track roller 29 disposed on the front side of both roller brackets 27 comes into contact with the rail portion 22.

  Further, when both roller brackets 27 rotate about the first magnetic body 18, the track rollers 29 arranged on the back side of both roller brackets 27 abut against the rail portion 22, and as a result, both roller brackets 27 are By contacting the rail portion 22 at two points of the front and rear track rollers 29, the rotation of the both roller brackets 27 around the first magnetic body 18 is restricted.

  In addition, the traveling body 7 and the belt bracket 17 of the present embodiment comprise the first magnetic body 18 and the second magnetic body 19 as permanent magnets, and both the first magnetic body 18 and both the second magnetic bodies 19. Even if the driving connection between the first magnetic body 18 and the second magnetic body 19 is released due to the external force such as an inertial force acting on the traveling body 7 by disposing the different magnetic poles to each other, the front of the traveling body 7 The first magnetic body 18 and the second magnetic body 19 disposed at the rear part of the belt bracket 17 or the first magnetic body 18 and the front part of the belt bracket 17 disposed at the rear part of the traveling body 7. Since the arranged second magnetic body 19 is driven and connected by magnetic force, the traveling body 7 can continue to travel on the order conveying path 1a.

  As described above, in the food and drink transport device 1 according to the present embodiment, the traveling body 7 includes the roller bracket 27 that has the load roller 28 and is pivotally supported by the pivot that faces the vertical direction. Since the first magnetic body 18 is mounted on the same axis of the pivot, and the second magnetic body 19 is disposed opposite to the first magnetic body 18, the traveling body 7 is connected to the first conveying path 1 a. When traveling on one corner 10a, there is no difference in the trajectory between the pivot axis of the roller bracket 27 and the first magnetic body 18, so that the first magnetic body 18 and the second magnetic body 19 are always arranged opposite to each other. While always connecting the first magnetic body 18 and the second magnetic body 19 by the magnetic force, the traveling body 7 can be reliably traveled on the order conveying path 1a while maintaining the stability of food and drink.

  In addition, since the first magnetic body 18 and the second magnetic body 19 are provided in pairs in the front-rear direction with respect to the traveling direction of the traveling body 7, the traveling body 7 and the belt bracket 17 are connected to the first magnetic body 18. And the second magnetic body 19 are connected at two points in the front and rear directions, and the direction of the traveling body 7 can be surely sequentially changed along the first corner 10a.

  Further, since the roller bracket 27 is provided with the support roller 31 that contacts the mounting portion 25, when the traveling body 7 travels the first corner 10a, the roller bracket 27 rotates to rotate the roller bracket 27. Since the friction force generated between the roller bracket 27 and the mounting portion 25 can be reduced by the support roller 31, the roller bracket 27 smoothly rotates at the first corner 10a, and the roller bracket 27 and the mounting portion 25 Noise, vibration, etc. generated between the two can be reduced.

  Further, the belt bracket 17 is provided with a running roller 41 that is in contact with the order conveying path 1a and prevents the second magnetic body 19 from being lifted by the magnetic force between the first magnetic body 18 and the second magnetic body 19. Therefore, when the traveling roller 41 comes into contact with the order conveying path 1 a, the second magnetic body 19 is directed toward the first magnetic body 18 of the second magnetic body 19 due to the magnetic force between the first magnetic body 18 and the second magnetic body 19. Therefore, when the driving belt 15 is driven without the second magnetic body 19 coming into contact with the order conveying path 1a, a frictional force is generated between the second magnetic body 19 and the order conveying path 1a. Occurrence is avoided, and the upward swing of the drive belt 15 connected to the belt bracket 17 is restricted, so that the drive belt 15 can be driven smoothly.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the said Example, although food / beverage was demonstrated as sushi, it is not limited to this, Various food / beverage is applicable.

  In the above-described embodiment, the support roller 31 as a rolling element is pivotally supported on the pivot extending from the sub bracket 30 attached to the roller bracket 27, and the upper end portion of the support roller 31 is brought into contact with the base portion 26. The roller bracket 27 is pivotally supported around the first magnetic body 18 while supporting the load of the food and drink dish 6 by the support roller 31. A hemispherical concave portion is formed, and a spherical body made of metal or the like is disposed as a rolling element in the concave portion, and the spherical body is brought into contact with the base portion 26 so that the roller bracket 27 and the base portion 26 are interposed. The generated frictional force may be further reduced.
