Food and drink conveying device
An object of the invention is to provide a food and drink conveying device that can allow a travel body to travel stably over a travel path. A food and drink conveying device ( 1 ) can allow a travel body ( 7 ) to travel over a travel path ( 1 a ) using a magnetic force between a first magnetic body ( 18 ) and a second magnetic body ( 19 ) by driving a conveyor driving body ( 15 ) and is provided with a lift preventing means ( 34 ) in close proximity to the second magnetic body ( 19 ), where the lift preventing means ( 34 ) makes contact with the travel path ( 1 a ) so as to prevent the second magnetic body ( 19 ) from lifting due to the magnetic force between the first magnetic body and the second magnetic body ( 19 ) and moves together with the conveyor driving body ( 15 ).
1. A food and drink conveying device, comprising:
a travel path;
a conveyor driving body provided beneath the travel path along the travel path; and
a travel body having a first magnetic body underneath said travel body, said first magnetic body being positioned to travel over said travel path with food or drink placed on top of said travel body, wherein
a second magnetic body having a polarity opposite to that of said first magnetic body is connected to an upper portion of said conveyor driving body beneath said travel path with a connection portion provided between, whereby said travel body travels over said travel path as a result of magnetic force between said first magnetic body and said second magnetic body when said conveyor driving body is driven,
a lift preventing means for preventing said second magnetic body from being lifted due to the magnetic force between said first magnetic body and said second magnetic body, which moves together with said conveyor driving body, is provided in a vicinity of said second magnetic body so as to make contact with said travel path,
said lift preventing means comprises a pair of rollers which make contact with said travel path and rotate so that said lift preventing means move together with said conveyor driving body,
the pair of rollers are aligned in a direction in which said conveyor driving body is driven, and
said second magnetic body is provided between said pair of rollers.
2. A food and drink conveying device, comprising:
a travel path;
a conveyor driving body provided beneath the travel path along the travel path; and
a travel body having a first magnetic body underneath said travel body, said first magnetic body being positioned to travel over said travel path with food or drink placed on top of said travel body, wherein
a second magnetic body having a polarity opposite to that of said first magnetic body is connected to an upper portion of said conveyor driving body beneath said travel path with a connection portion provided between, whereby said travel body travels over said travel path as a result of magnetic force between said first magnetic body and said second magnetic body when said conveyor driving body is driven,
a lift preventing means for preventing said second magnetic body from being lifted due to the magnetic force between said first magnetic body and said second magnetic body, which moves together with said conveyor driving body, is provided in a vicinity of said second magnetic body so as to make contact with said travel path,
said lift preventing means comprises a pair of rollers which make contact with said travel path and rotate so that said lift preventing means move together with said conveyor driving body,
the pair of rollers are aligned in a direction perpendicular to a direction in which said conveyor driving body is driven, and
said second magnetic body is provided between said pair of rollers.
3. A food and drink conveying device, comprising:
a travel path;
a conveyor driving body provided beneath the travel path along the travel path; and
a travel body having a first magnetic body underneath said travel body, said first magnetic body being positioned to travel over said travel path with food or drink placed on top of said travel body, wherein
a second magnetic body having a polarity opposite to that of said first magnetic body is connected to an upper portion of said conveyor driving body beneath said travel path with a connection portion provided between, whereby said travel body travels over said travel path as a result of magnetic force between said first magnetic body and said second magnetic body when said conveyor driving body is driven, and
a lift preventing means for preventing said second magnetic body from being lifted due to the magnetic force between said first magnetic body and said second magnetic body, which moves together with said conveyor driving body, is provided in a vicinity of said second magnetic body so as to make contact with said travel path, and
further comprising a support means for supporting said connection portion for connecting said second magnetic body to said conveyor driving body provided along said travel path.
4. A food and drink conveying device, comprising:
a travel path;
a conveyor driving body provided beneath the travel path along the travel path; and
a travel body having a first magnetic body underneath said travel body, said first magnetic body being positioned to travel over said travel path with food or drink placed on top of said travel body, wherein
a second magnetic body having a polarity opposite to that of said first magnetic body is connected to an upper portion of said conveyor driving body beneath said travel path with a connection portion provided between, whereby said travel body travels over said travel path as a result of magnetic force between said first magnetic body and said second magnetic body when said conveyor driving body is driven,
a lift preventing means for preventing said second magnetic body from being lifted due to the magnetic force between said first magnetic body and said second magnetic body, which moves together with said conveyor driving body, is provided in a vicinity of said second magnetic body so as to make contact with said travel path, and
said first magnetic body is provided to said travel body so as to be movable in a direction perpendicular to a direction in which said travel body travels, and at least one of said second magnetic body and said travel path is provided with a movement regulating means for regulating the movement of said second magnetic body in the direction perpendicular to the direction in which said conveyor driving body is driven.
5. The food and drink conveying device according to claim 1 , further comprising a support means for supporting said connection portion for connecting said second magnetic body to said conveyor driving body provided along said travel path.
6. The food and drink conveying device according to claim 2 , further comprising a support means for supporting said connection portion for connecting said second magnetic body to said conveyor driving body provided along said travel path.
7. The food and drink conveying device according to claim 1 , wherein said first magnetic body is provided to said travel body so as to be movable in a direction perpendicular to a direction in which said travel body travels, and at least one of said second magnetic body and said travel path is provided with a movement regulating means for regulating the movement of said second magnetic body in the direction perpendicular to the direction in which said conveyor driving body is driven.
