Tray transport system

Abstract

To smoothly perform processing of providing a tray on which food and drink are placed to a customer seat and processing of collecting the used tray from the customer seat.SOLUTION: A tray conveyance system (1) includes a providing conveyance path (OP), a collecting conveyance path (CP), and tray lowering units (50). The providing conveyance path (OP) conveys a tray (TR) on which food and drink are placed to a customer seat (T). The collecting conveyance path (CP) is disposed below the providing conveyance path (OP) along the providing conveyance path (OP), and conveys the used tray (TR). The tray lowering units (50) are disposed at one end of each of the providing conveyance path (OP) and the collecting conveyance path (CP), and operate between a receiving position where the tray (TR) is received from the providing conveyance path (OP) and a sending position where the tray (TR) is sent to the collecting conveyance path (CP).SELECTED DRAWING: Figure 4

Claims

1. A service transport route for carrying trays of food and beverages to the customer seats, A collection transport path is located below the aforementioned supply transport path and transports used trays, A tray lowering unit is positioned at one end of the supply transport path and the collection transport path, and operates between a receiving position where a tray is received from the supply transport path and a sending position where a tray is sent to the collection transport path. The tray lowering unit has a dispensing table located on the side opposite to the supply transport path, The tray lowering unit is A transport unit including a roller that contacts a tray and a drive mechanism that rotates the roller, The transport unit has a lifting mechanism for moving it between the receiving position and the sending position, The tray transport system is characterized in that the drive mechanism rotates the rollers to move the tray to the dispensing table when an object is placed on the tray that has been moved to the transport unit.

2. The tray transport system according to claim 1, characterized in that the drive mechanism changes the rotation direction of the rollers when the transport unit is in the receiving position and when the transport unit is in the sending position.

3. The tray transport system according to claim 1, characterized in that the lifting mechanism moves the transport unit from the receiving position to the delivery position when there is no object placed on the tray that has been moved to the transport unit.

4. A serving transport path for transporting trays on which food and beverages are placed to the customer seats, A collection transport path is located below the aforementioned supply transport path and transports used trays, A tray lowering unit is positioned at one end of the supply transport path and the collection transport path, and operates between a receiving position where a tray is received from the supply transport path and a sending position where a tray is sent to the collection transport path. A tray lifting unit that operates between a receiving position where the tray is received from the aforementioned collection transport path and a sending position where the tray is sent to the aforementioned supply transport path, A stopper unit that operates between a position that prevents the tray from moving from the recovery transport path to the tray lifting unit and a position that allows the tray to move from the recovery transport path to the tray lifting unit, When the tray lifting unit is in the delivery position, a tray extrusion unit pushes the tray on the tray lifting unit toward the supply transport path, The system includes an information writing unit that supports the tray extruded by the tray extrusion unit, The aforementioned information writing unit is, An information writing unit that writes predetermined information to the memory built into a container placed on a supporting tray, A lifting mechanism that raises and lowers the information writing unit between a raised position that supports the tray above the aforementioned transport path and a lowered position that brings the tray into contact with the transport path, A tray transport system characterized by having the following features.

5. When the information writing unit is in the raised position, it writes predetermined information to the memory. The tray transport system according to claim 4, characterized in that the lifting mechanism moves the information writing unit from the raised position to the lowered position after the writing of predetermined information to the memory is completed.

6. A serving transport path for transporting trays on which food and beverages are placed to the customer seats, A collection transport path is located below the aforementioned supply transport path and transports used trays, A washing machine is placed in the middle of the aforementioned collection and transport path to wash used trays, A tray lowering unit is positioned at one end of the supply transport path and the collection transport path, and operates between a receiving position where a tray is received from the supply transport path and a sending position where a tray is sent to the collection transport path. A tray lifting unit that operates between a receiving position where the tray is received from the aforementioned collection transport path and a sending position where the tray is sent to the aforementioned supply transport path, A stopper unit that operates between a position that prevents the tray from moving from the recovery transport path to the tray lifting unit and a position that allows the tray to move from the recovery transport path to the tray lifting unit, A tray transport system characterized by having the following features.

7. The tray transport system according to any one of claims 1 to 6, characterized in that it has a tray transport mechanism positioned below the collection transport path along at least a portion of the collection transport path, for transporting boxes containing used containers.
