Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a food and beverage transport apparatus that transports a plurality of food and beverage transport bodies placed on a transport path using magnetic force.
[0002]
[Prior art]
Conventionally, the food and drink conveying device of a sushi restaurant commonly called a sushi bar includes a crescent chain conveyor in which a large number of stats having a substantially half-moon shape in plan view are rotatably attached to an endlessly running chain. It is generally used.
[0003]
In the conventional crescent chain conveyor described above, a bent conveyance path is also planned, so that a required gap is provided between adjacent stats and connected to the chain so as to be relatively rotatable with each other. The movement of the stat is hindered by the entry of rice grains and other foreign matter into the garbage, so that the work of removing such foreign matter is troublesome and is not preferable in terms of hygiene.
[0004]
In order to solve this problem, in recent years, a magnetic transfer device as shown in FIG. 6 has been used. FIG. 6 is a partial cross-sectional view of a magnetic force type conveying device. The conveying means a includes an endlessly running chain b, a bracket c mounted at a predetermined interval above the chain b, and an upper surface of each bracket c. And a fixed permanent magnet d.
[0005]
The sushi plate g, which is a food and drink carrier with both sides of the outer peripheral portion supported on the conveying path surface e, has a magnetic metal piece h attached to the lower surface thereof close to the upper end of each of the permanent magnets d. It is held and circulated by the attraction force of the magnet d. In this case, all the polarities of the permanent magnets d are unified so that the lower side is the north pole and the upper side is the south pole (or vice versa).
[0006]
[Problems to be solved by the invention]
As described above, unlike the crescent chain conveyor, the magnetic-type conveying device as shown in FIG. 6 does not cause the stat to be locked by a foreign substance, but increases the weight of the food and drink conveying body or increases the weight of the conveying member on the conveying road surface. If there is any leftover food, the food and drink carrier will not be able to be transported smoothly. However, when a customer takes a sushi plate g, for example, there is a risk that the sushi plate g may fall due to a recoil.
[0007]
In addition, when the magnet strongly attracts the food and drink carrier, a large frictional force is generated between the conveyance path surface on which the food and drink carrier slides and the food and drink carrier, and represents the locus of the food and drink carrier on the transfer path surface e. Not only was a linear scratch formed, making the appearance worse, but also this scratch caused the sliding of the food and beverage carrier.
[0008]
The present invention has been made in order to solve the above problems, and the weight of the food and drink carrier is slightly increased, even if there is leftover food on the conveying road surface, without increasing the suction force, It is an object of the present invention to provide a food and beverage transport device that can smoothly transport a food and beverage transport body and does not damage the transport path.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, a food and beverage transporting device of the present invention is a food and beverage transporting device that transports a plurality of food and beverage carriers placed on a transport path using magnetic force, wherein the food and beverage A first magnetic material is provided on the carrier, and a plurality of second magnetic materials attracting the first magnetized material are arranged below the conveyance path at regular intervals so as to be able to circulate and travel. The food / drink transporter runs on the transport path by wheels.
According to the present invention, the food transporter can travel on the transport path by the wheels, so the frictional resistance between the food transporter and the transport path surface is reduced, and the food transporter can be used without increasing the attractive magnetic force. It can be transported smoothly, and the transport path is not damaged.
[0010]
In the transport device, a third magnetic material that repels the second magnetic material is separated from the first magnetic material by a distance substantially half a distance between two adjacent second magnetic materials in the food and drink transporting body. It is preferable that it is provided.
This makes it possible to reduce the pressing force of the wheels on the transport path in a well-balanced manner.
[0011]
In the above-described transport device, it is preferable that the wheels are provided two at each of front and rear.
In this way, the food and beverage carrier can always run stably in the front, rear, left and right directions.
[0012]
In the transport apparatus, the transport path is preferably an endless circulating transport path.
In this way, even in a circulating transport path in which a part of the transport path is a bent portion, unlike the crescent chain, stable travel is possible without restriction of movement by food and drink.
[0013]
In the transport device, the food and beverage transport body is preferably a transported food and beverage, and the transport path is a lowered transport path.
In this way, the left and right foods are unevenly distributed and eaten and drunk, and the food is stably eaten and drinkable even on the lowered conveyance path where food residues are scattered on the conveyance path surface. Can be transported.
[0014]
In the transport device, it is preferable that one of the food transporter and the transport path protrudes from the other, and the first and second magnetic materials are provided so as to be close to each other.
With this configuration, even if the bottom surface position of the food and drink transport body is separated from the transport road surface by the wheels, the distance between the first magnetic material and the second magnetic material can be reduced, so that the attractive magnetic force can be effectively held. .
[0015]
In the transport device, it is preferable that a part of the plurality of food and drink transport bodies is connected.
In this way, even if the single container does not survive, it can be placed and transported.
[0016]

The tray 16 is rotatably supported by two wheels in front and back of a tray body 18 so as to be able to always run stably on the running surface 8a in the front-rear and left-right directions. A housing 18b is formed so as to protrude downward at a position forward in the direction, and a first magnetic material 14 is attached to a lower end of the housing 18b so as to approach the running surface 8a.
[0022]
As shown in FIGS. 2 and 3, a pair of third magnetic members 15 a is located at a position rearward in the transport direction on the lower surface of the tray 10 and at an equal distance from the axis passing through the center in the width direction. , 15b. The third magnetic members 15a, 15b are arranged such that the second magnetic members 4, which are attached at regular intervals in the transport direction of the chain 2, attract the first magnetic body 14.

That is, the third magnetic members 15a and 15b are separated from the first magnetic member 14 by a distance substantially half the distance between two adjacent second magnetic members 4 and 4.
[0023]
More specifically, the second magnetic material 4 is made up of permanent magnets attached at predetermined intervals to the upper part of the chain 2 running at the center in the width direction of the lower surface of the running surface 8a, and at a position close to the running surface 8a. It is configured to run. Since the first magnetic member 14 is formed to protrude downward and is provided at the lower end of the housing 18b and has a positional relationship close to each other with the second magnetic member 4, it is not necessary to increase the attractive magnetic force. Can also transfer the tray 10 smoothly.
[0024]
Therefore, all the polarities of the second magnetic material 4 are unified so that the upper side becomes the N pole and the lower side becomes the S pole as shown in FIG. 3 and FIG. Of the magnetic material 14 is disposed such that its lower surface is an S pole whose polarity is opposite to that of the second magnetic material 4 and its upper surface is an N pole.
[0025]
Further, the pair of third magnetic members 15a and 15b disposed behind the first magnetic member 14 has a lower surface having an N-pole having the same polarity as the second magnetic material 4 and an upper surface having an S-pole. It is arranged so that it becomes.
[0026]
Next, the operation of the food and beverage transport apparatus configured as described above will be described with reference to FIGS.

The second magnetic members 4 attached to the upper portion of the chain 2 at regular intervals have a magnetic force of, for example, 4500 gauss and have the first magnetic member 14 or a pair of third magnetic members attached to the lower surface of the tray 10. 15a and 15b each have a magnetic force of 2600 gauss.
[0028]
Then, when the chain 2 is run by driving the motor, the second magnetic material 4 moves with the N pole toward the upper side while maintaining a predetermined interval together with the running of the chain 2 as shown in FIGS. 3 and 4. .
[0029]
Therefore, as shown in FIG. 4, the tray 10 placed on the running surface 8a is configured such that the first magnetic material 14 is attracted to the second magnetic material 4 having the opposite polar relationship, and the pair of left and right The third magnetic members 15a and 15b give a floating force to the tray 10 by the repulsive force of the two second magnetic members 4 sandwiching the magnetic members 15a and 15b, and at the same time, the repulsive force of the third magnetic members 15a and 15b. The center of the rear of the tray 10 is centered on the transport center line of the chain 2 by the balance of the above.
[0030]
That is, according to the food and beverage transport apparatus configured as described above, the tray 10 can travel on the transport path 8 by the wheels 16, so that the frictional resistance between the transport body 10 and the travel surface 8a decreases, The tray 10 can be transported smoothly without increasing the attractive magnetic force, and the running surface 8a is not scratched.
