Summary of the Invention

Problems to be Solved by the Invention

[0004] In the food and beverage conveying device described in Patent Document 1, among the guide means provided on the curved path of the order conveyance path, the outer peripheral surface of the first guide means (fixed guide body or rotating body) that guides the outer peripheral belt of the belt body is a vertical surface, so there is a risk of the following problems occurring. That is, since the traveling speed of the belt body on the order conveyance path is relatively fast, the outer peripheral belt may lift off from the first guide means on the curved path due to centrifugal force, vibration, and meandering when the belt body travels on a curved path bent at 90 degrees.

[0005] In such a case, the outer peripheral side belt cannot stably travel in the traveling direction while maintaining a horizontal position on the curved path, and abnormal noise may occur between the regulating roller of the belt bracket attached to the outer peripheral side belt and the rail portion. To address this problem, it is conceivable to provide regulating means for preventing the lifting of the outer peripheral side belt on the curved path. However, if such regulating means is provided, not only will the running resistance of the belt body increase due to friction, but also a problem will occur in that frictional noise is generated between the belt body and the regulating means. Further, due to the resistance between the belt body and the regulating means, there is also a problem that it leads to wear and breakage of the belt.

[0006] The present invention has been made paying attention to such problems, and an object thereof is to provide a food and beverage conveying device capable of preventing the lifting of an outer peripheral side belt traveling on a curved path without separately providing regulating means for preventing lifting.

Means for Solving the Problems

[0007] In order to solve the above problems, the food and beverage conveying device of the present invention includes a traveling lane having at least a part of a curved path, a belt body that travels endlessly along the traveling lane, and a traveling body on which food and beverage are placed and that can travel along the traveling lane, and in the food and beverage conveying device provided with guide means for guiding the belt body along the traveling direction on the curved path, the guide means includes first guide means arranged along the inner surface of an outer peripheral side belt that travels on the outer peripheral side of the curved path in the belt body, and second guide means arranged along the outer surface of an inner peripheral side belt that travels on the inner peripheral side of the curved path in the belt body, The first guide means is composed of a plurality of guide rollers pivotally supported on a vertical support shaft so as to be horizontally rotatable, at least the the outer peripheral surface of the guide roller located at the central portion of the curved path is formed on a tapered inclined surface forming an inverted V shape with respect to the support shaft is characterized by According to this feature, by making the outer peripheral surface of the first guide means located at least at the central part of the curved path an inclined surface that slopes in the outer diameter direction of the curved path from the lower end to the upper end, the upward movement of the outer peripheral belt is restricted. Therefore, even if centrifugal force, vibration, or snake movement acts on the outer peripheral belt running on the curved path, it is prevented from lifting, and the outer peripheral belt can stably run while maintaining a horizontal position on the curved path. Also, since there is no need to separately provide a restricting means for preventing the outer peripheral belt from lifting on the curved path, the running resistance of the belt body does not increase and no frictional noise is generated.

[0008] The first guide means is composed of a plurality of guide rollers that can rotate horizontally, and the outer peripheral surface of the guide roller arranged at least at the central part of the curved path is formed as a tapered inclined surface having an inverted V shape. According to this feature, the outer peripheral belt can be smoothly guided by the plurality of guide rollers and run smoothly on the outer peripheral side of the curved portion without resistance, and the inverted V-shaped tapered inclined surface of the guide roller arranged at the central part of the curved path can effectively prevent the outer peripheral belt from lifting.

[0009] Among the plurality of guide rollers, the outer peripheral surfaces of the guide rollers arranged at both ends of the curved path are each formed as a tapered inclined surface having a V shape. According to this feature, the downward movement of the outer peripheral belt caused by the inverted V-shaped tapered inclined surface of the guide roller arranged at the central part of the curved path can be balancedly corrected to move upward by the V-shaped tapered inclined surfaces of the guide rollers arranged at both ends of the curved path, so that the outer peripheral belt can run more stably while maintaining a horizontal position on the curved path.

[0010] An endless sub-belt is wound around the plurality of guide rollers constituting the first guide means. According to this feature, a sub-belt that runs on the outer peripheral side is interposed between the outer peripheral side belt and a plurality of guide rollers, and the outer peripheral side belt is guided by the outer surface of the sub-belt that runs on the outer peripheral side. Therefore, the outer peripheral side belt can run smoothly. Further, since the outer peripheral side belt does not come into direct contact with the guide rollers, no abnormal noise will occur even when a toothed belt body is used. Furthermore, with respect to the sub-belt on the outer peripheral side that runs while inclining along the tapered inclined surface of the guide roller, the contact area of the outer peripheral side belt becomes longer in the running direction. Therefore, it is possible to effectively prevent the outer peripheral side belt running on a curved path from floating up.

[0011] It is characterized in that large-diameter flange portions are respectively formed at the lower ends of the guide rollers arranged at both end portions and the central portion of the curved path. According to this feature, it is possible to prevent the sub-belt from moving downward and shifting in position, and also to restrict the outer peripheral side belt from moving downward.

[0012] The second guide means is composed of a plurality of guide rollers that can rotate horizontally, and the outer peripheral surfaces of the respective guide rollers are formed on tapered inclined surfaces having an inverted V shape. According to this feature, the inner peripheral side belt of the belt body can be guided by the plurality of guide rollers and smoothly run along the inner peripheral side of the curved portion without resistance. Also, since the inner peripheral side belt can be prevented from floating up by the tapered inclined surface having an inverted V shape, the belt body can stably run while maintaining a horizontal state in the curved portion.

Embodiments for Carrying out the Invention

[0014] Embodiments for carrying out the food and beverage conveying device according to the present invention will be described below based on examples.

Examples

[0015] The food and beverage conveying device according to the example will be described with reference to FIGS. 1 to 6. In the following, the back side of the paper of FIGS. 4 to 6 will be described as the front side of the traveling body. In FIG. 1, reference numeral 1 indicates a food and beverage conveying device to which the present invention is applied. This food and beverage conveying device 1 is provided across, for example, a kitchen area C where kitchen staff C1, C2 cook food and beverages such as sushi in a revolving sushi restaurant and a dining area A where customers eat and drink, and includes order conveying paths 1a, 1b, 2 as the traveling lanes of the present invention.

[0016] An endless circulating conveying path 3 configured in an L shape in plan view along the tables T1 to T4 in the dining area A is installed around the order conveying paths 1a, 1b, 2. The circulating conveying path 3 includes a crescent chain conveyor 4 that endlessly rotates, and the food and beverage plate 5 on which food and beverages are placed is circulated and conveyed by driving this crescent chain conveyor 4.

[0017] In a revolving sushi restaurant or the like where such a circulating conveying path 3 and order conveying paths 1a, 1b, 2 are installed, a diner can take out and eat the food and beverages circulated and conveyed by the circulating conveying path 3, and when eating food and beverages that are not circulated and conveyed on the circulating conveying path 3, they can place an individual order and have it conveyed by the order conveying paths 1a, 1b, 2.

[0018] That is, the individually ordered food and drink is cooked in the kitchen area C and then conveyed to the food server area B by any one of the three order conveyance paths 1a, 1b, and 2 arranged in the kitchen area C. Specifically, when an order for food and drink is received from a customer in the dining area A, the ordered food and drink is cooked in the kitchen area C partitioned by the partition wall W and placed on a food and drink plate 5 (see FIG. 4). The food and drink plate 5 on which the ordered food and drink is placed is placed on a traveling body 6 that reciprocates on the order conveyance paths 1a, 1b, and 2 and is conveyed to the food server area B. The food and drink plates 5 conveyed by the left and right order conveyance paths 1a and 1b close to the dining area A are directly taken out by the customers in the dining area A, and the food and drink plates 5 conveyed by the central order conveyance path 2 are handed to the customers by the food server. After conveying the ordered food and drink, the traveling body 6 returns to the kitchen area C side.

[0019] As shown in FIG. 1, the rear portions of the order conveyance paths 1a, 1b, and 2 extend linearly from the kitchen area C side through the openings formed in the partition wall W toward the dining area A side. The order conveyance path 2 is linearly arranged in the center so as to divide the food server area B into two parts.

[0020] The order conveyance paths 1a and 1b are bent in a direction away from the central order conveyance path 2 to the left and right near the partition wall W and then extend linearly to near the inner side of the circulation conveyance path 3, and further extend linearly forward along both the left and right sides of the circulation conveyance path 3. Specifically, the order conveyance path 1a is formed with a first curved path 10a (right curve) and a second curved path 11a (left curve) that bend at 90 degrees near the partition wall W, and the order conveyance path 1b is formed with a first curved path 10b (left curve) and a second curved path 11b (right curve) that bend at 90 degrees in the opposite direction, which are formed symmetrically with the order conveyance path 1a with respect to the left and right.

[0021] Next, the configurations of the order conveyance paths 1a, 1b, 2 and the traveling body 6 will be described. Note that although the shapes of the order conveyance paths 1a, 1b, and 2 are different from each other, the basic structures for running the traveling body 6 are all the same. Therefore, in the following, only the order conveyance path 1a will be described, and the descriptions of the order conveyance paths 1b and 2 will be omitted.

[0022] As shown in Fig. 2, below the conveying surface 7 on the upper surface of the order conveying path 1a, a driving sprocket 8 that is horizontally rotationally driven in the clockwise direction in a plan view by a driving motor (not shown) is provided at the end on the kitchen area C side, and a driven sprocket 9 that is horizontally rotatable in the clockwise direction in a plan view is provided at the end on the food distribution area B side. An endless toothed belt body 13 is wound around between the driving sprocket 8 and the driven sprocket 9. The driven sprocket 9 is connected to a tension adjusting mechanism 9a for applying tension to the belt body 13. In this embodiment, a toothed belt body 13 is used, but a flat belt body can also be used. In this case, the driving sprocket 8 and the driven sprocket 9 may be changed to a driving pulley and a driven pulley.

[0023] The belt body 13 runs endlessly along the conveying surface 7 in the internal space of the order conveying path 1a. That is, when the driving sprocket 8 is rotationally driven in the clockwise direction in a plan view, one side (left side) of the belt body 13 travels forward from the kitchen area C toward the food distribution area B, and the other side (right side) of the belt body 13 whose direction is changed by the driven sprocket 9 travels so as to return from the food distribution area B toward the kitchen area C.

[0024] As shown in Figs. 2 and 4, a plurality of belt guides 14 for guiding the belt body 13 are provided in the internal space of the straight path 12a of the order conveying path 1a. The belt guide 14 has two guide grooves 14a, 14a that open upward in the traveling direction of the belt body 13. The forward and return sides of the belt body 13 are guided by these guide grooves 14a, 14a, so that the belt body 13 is prevented from moving in the width direction and can travel.

[0025] As shown in FIGS. 4 to 6, at a predetermined position in the longitudinal direction of the belt body 13 arranged on the left side, a plurality of belt brackets 15 having an inverted L shape for conveying the traveling body 6 are attached so as to sandwich the belt from the left and right width directions. On the upper surface of the horizontal piece 15a facing the right side of the belt bracket 15, the central portion of the conveying bracket 16 is bolted, and traveling rollers 17, 17 that can rotate around a horizontal axis are attached to both side surfaces in the width direction of the conveying bracket 16. The traveling rollers 17, 17 are configured to roll along the upper surfaces of the horizontal traveling plates 19, 19 at the upper ends of a plurality of support columns 18, 18 provided along the traveling direction in the internal space of the order conveying path 1a.

[0026] On the upper surface of the conveying bracket 16, a pair of track rollers 20, 20 that rotate around a vertical axis are attached, and the track rollers 20, 20 are configured to roll in proximity to the vertical inner surface of a rail portion 21 having a downward U-shaped cross section protruding from the central portion in the width direction of the conveying surface 7 of the order conveying path 1a. Thereby, the conveying bracket 16 can stably move in the order conveying path 1a together with the belt body 13 without lateral displacement in the width direction.

[0027] As shown in FIG. 4, the traveling body 6 includes a carriage portion 22 that travels on the conveying surface 7, and a tray portion 23 that is attached to the upper surface of the carriage portion 22 and on which a food and drink plate 5 on which an ordered food and drink S is placed is placed. The carriage portion 22 includes a base portion 24 having a downward U-shaped cross section slightly smaller than the width dimension of the conveying surface 7, and a pair of roller brackets 25, 25 having an inward L-shaped cross section fixed to the lower surface of the base portion 24 on both sides sandwiching the rail portion 21.

[0028] At both lower end pieces 24a, 24a in the width direction of the base portion 24, two front and rear load-bearing rollers 26, 26 each rotating about a horizontal axis along the conveying surface 7 are pivotally supported. Further, on the inward horizontal pieces 25a, 25a of the roller brackets 25, 25, two front and rear anti-vibration rollers 27, 27 each rotating horizontally along the outer surface of the rail portion 21 are pivotally supported. Note that the width dimension between the anti-vibration rollers 27, 27 is set to be slightly smaller than the width dimension of the inner surface of the rail portion 21. By these multiple load-bearing rollers 26 and anti-vibration rollers 27, the carriage portion 22 can run smoothly along the conveying surface 7 without lateral swaying.

[0029] Inside a tray attachment member 28 having a U-shaped cross section that opens downward and is provided at the central portion in the width direction of the base portion 24, a first magnetic body 29 made of a ferromagnetic metal or a permanent magnet is attached. This first magnetic body 29 faces a second magnetic body 30 attached to the upper surface at the central portion in the width direction of the conveying bracket 16 and is attracted to each other by magnetic force. Note that either one of the first magnetic body 29 and the second magnetic body 30 is formed of a ferromagnetic metal and the other is formed of a permanent magnet, or both are formed of permanent magnets with different magnetic poles. By the attraction between these first magnetic body 29 and second magnetic body, the conveying bracket 16 and the base portion 24 are indirectly connected. Therefore, when the belt body 13 is driven, the traveling body 6 travels on the conveying surface 7 along the order conveying path 1a.

[0030] As shown in FIGS. 2, 3, 5, and 6, at the central portion and closer to the inner peripheral side inside the first curved path 10a and the second curved path 11a of the order conveying path 1a, a plurality (nine in the embodiment) of outer guide rollers 31 and inner guide rollers 32 as the first guide means and the second guide means are provided at regular intervals along the curvature of the first curved path 10a and the second curved path 11a. Note that since the first curved path 10a, the second curved path 11a, and the outer guide rollers 31 and inner guide rollers 32 provided thereon have the same configuration except that the positional relationship is reversed, only the first curved path 10a will be described below, and the description of the second curved path 11a will be omitted.

[0031] The outer guide rollers 31 and the inner guide rollers 32 of the first curved path 10a are pivotally supported horizontally rotatably via ball bearings 34, 34 on vertical support shafts 33, 33 which are erected at regular intervals at the central part and the inner peripheral side of the bottom surface in the first curved path 10a. Each ball bearing 34 is prevented from coming off by a snap ring 35 and a holding member 36 bolted to the support shaft 33. The vertical dimension of the outer guide roller 31 is made larger than the vertical dimension of the belt body 13 so as to protrude above the upper end of the belt body 13. The vertical dimension of the inner guide roller 32 is made smaller than the vertical dimension of the outer guide roller 31, and is pivotally supported so that the height is lower than that of the outer guide roller 31.

[0032] As shown in FIG. 3, the outer peripheral surfaces of the seven outer guide rollers 31 excluding the two outer guide rollers 31 arranged at both ends on the outer peripheral side of the first curved path 10a and all the inner guide rollers 32 are formed on tapered inclined surfaces 31a, 32a having an inverted V shape as shown in FIG. 5. Further, as shown in FIG. 6, the outer peripheral surfaces of the two outer guide rollers 31 at both ends of the first curved path 10a are formed on tapered inclined surfaces 31b having a V shape with an inclination opposite to that of the tapered inclined surfaces 31a, 32a. In this embodiment, the inclination angles of the tapered inclined surfaces 31a, 31b, 32a are set to about 3 degrees. As shown in FIGS. 3, 5, and 6, large-diameter flange portions 31c are formed at the lower ends of the one outer guide roller 31 arranged at the central part of the first curved path 10a and the two outer guide rollers 31 at both ends, respectively.

[0033] An endless sub-belt 37 is wound around the outer peripheral surfaces of all the outer guide rollers 31. The sub-belt 37 running on the outer peripheral side of the first curved path 10a runs on the outer peripheral side of the first curved path 10a while being in surface contact with the tapered inclined surfaces 31a, 31b on the outer surface side of each outer guide roller 31 and being inclined at the same angle as the tapered inclined surfaces 31a, 31b. The sub-belt 37 is prevented from moving downward by the large-diameter flange portions 31c at the lower ends of the three outer guide rollers 31 arranged at the central part and both ends of the first curved path 10a.

[0034] As shown in FIG. 5, the inner surface (the surface in the inner diameter direction) of the outer peripheral side belt 13a that travels on the outer peripheral side of the first curved path 10a on the left side of the belt body 13, that is, where the belt bracket 15 is attached, travels forward while its upper part contacts the inclined surface of the upper part of the outer surface of the sub-belt 37 that travels on the outer peripheral side, excluding both ends. Further, as shown in FIG. 6, the inner surface of the outer peripheral side belt 13a to which the belt bracket 15 is attached and that is guided by the outer guide rollers 31 at both ends travels forward while its lower part contacts the inclined surface of the lower part of the outer surface of the sub-belt 37 that travels on the outer peripheral side.

[0035] By looping the sub-belt 37 around the outer guide rollers 31, the sub-belt 37 that travels on the outer peripheral side is interposed between the outer peripheral side belt 13a and the plurality of guide rollers 31, and the outer peripheral side belt 13a is guided by the outer surface of the sub-belt 37, so that the outer peripheral side belt 13a can travel smoothly. Further, since the outer peripheral side belt 13a does not directly contact the outer guide rollers 31, no abnormal noise is generated even when a toothed belt body 13 is used.

[0036] As shown in FIG. 3, the sub-belt 37 that feeds back on the inner peripheral side of the first curved path 10a is separated from all the outer guide rollers 31 except the outer guide rollers 31 at both ends in the inner diameter direction by the tension of the belt, and is in surface contact with the outer surface (the surface in the outer diameter direction) of the inner peripheral side belt 13b that travels on the inner peripheral side of the first curved path 10a and presses the inner peripheral side belt 13b in the inner diameter direction. As a result, as shown in FIG. 5, the inner peripheral side belt 13b can stably travel in the return direction along the first curved path 10a while being sandwiched between the tapered inclined surface 32a on the outer surface side of the inner guide roller 32 and the sub-belt 37 that feeds back on the inner peripheral side.

[0037] As described above, in the food and drink conveying device 1 according to the embodiment, the outer peripheral surfaces of seven outer guide rollers 31, excluding the two outer guide rollers 31 arranged at both end portions on the outer peripheral side of the first curved path 10a, are formed into tapered inclined surfaces 31a having an inverted V shape, and the outer peripheral surfaces of the two outer guide rollers 31 at both end portions of the first curved path 10a are formed into tapered inclined surfaces 31b having an inverted inclined V shape. As a result, the outer peripheral side of the sub-belt 37 wound around the outer guide roller 31 also inclines at the same angle as the tapered inclined surfaces 31a and 31b and runs. Therefore, the upper part of the inner surface of the outer peripheral side belt 13a contacts the upper part of the outer surface of the inclined surface that inclines in the outer diameter direction excluding both end portions of the sub-belt 37 (see FIG. 5), and the lower part of the inner surface of the outer peripheral side belt 13a contacts the lower part of the outer surface of the inclined surface that inclines in the inner diameter direction of both end portions of the sub-belt 37 (see FIG. 6).

[0038] As a result, since the outer peripheral side belt 13a is restricted from moving upward by the inclined surface that inclines in the outer diameter direction of the sub-belt 37, the outer peripheral side belt 13a to which the belt bracket 15 is attached will not float even if centrifugal force, vibration, or meandering acts on it. Moreover, since the contact area of the outer peripheral side belt 13a with the sub-belt 37 that runs on the outer peripheral side is long in the running direction, the floating of the outer peripheral side belt 13a can be effectively prevented.

[0039] Also, the tendency of the outer peripheral side belt 13a to move downward due to the inclined surface that inclines in the outer diameter direction of the sub-belt 37 that runs on the outer peripheral side can be balanced and corrected to move upward by the inclined surfaces that incline in the inner diameter direction of both end portions of the sub-belt 37. Thus, the outer peripheral side belt 13a can stably run while maintaining a horizontal state along the first curved path 10a.

[0040] Furthermore, large-diameter flange portions 31c are formed at the lower ends of the three outer guide rollers 31 arranged at the central portion and both end portions of the first curved path 10a. As a result, the sub-belt 37 is prevented from moving downward and being displaced, and the downward movement of the belt body 13 is also restricted.

[0041] Furthermore, by forming the outer peripheral surfaces of all the inner guide rollers 32 into reverse V-shaped tapered inclined surfaces 32a, it is possible to prevent the inner peripheral belt 13b from lifting via the sub-belt 37 that runs on the inner peripheral side, and the entire belt body 13 can stably travel along the first curved path 10a while maintaining a horizontal position.

[0042] As described above, the embodiments of the present invention have been described with reference to the drawings. However, the specific configuration is not limited to these embodiments, and even if there are additions or changes within the scope that does not depart from the gist of the present invention, they are included in the present invention.

[0043] For example, in the above embodiment, the sub-belt 37 is looped around the outer guide roller 31. However, when a flat belt without teeth is used for the belt body 13, the sub-belt 37 may be omitted. In this case, the outer peripheral belt 13a will directly contact the tapered inclined surfaces 31a and 31b of the outer guide roller 31. Even in this case, the effect of preventing the outer peripheral belt 13a from lifting, which is the same as described above, can be obtained.

[0044] Also, in the above embodiment, the first guiding means is the guide roller 31. However, instead of the guide roller 31, for example, a fixed guide body in an arc shape in plan view as described in FIG. 3 of Patent Document 1 mentioned above may be used, and at least the outer peripheral surface located at the central portion of the curved path may be formed as an inclined surface that inclines in the outer diameter direction of the first curved path 10a from the lower end to the upper end.

[0045] Furthermore, in the above embodiment, the outer peripheral surface of the inner guide roller 32 is also formed as a reverse V-shaped tapered inclined surface 32a. However, the inner guide roller 32 may also be a vertical surface.

[0046] Furthermore, in the above embodiment, the first and second curved paths 10a and 11a are bent at 90 degrees. However, the present invention can also be applied to curved paths that bend at angles other than 90 degrees.
