Abstract
The Corona disaster increased the demand for vending machines due to contactless, non-personal demand. This led to the creation of various types of vending machines, including French food vending machines. Furthermore, the Corona Disaster triggered the popularity of camping alone, and the popularity of hot sandwiches heated up. From this, in anticipation of demand, the company set out to produce a hot sandwich vending machine. The hot sandwich vending machine consists of three parts: a mechanism for feeding the ingredients, a mechanism for stacking the ingredients, and a mechanism for cooking the hot sandwich. First, bread and ingredients are placed on a plate. The plate is connected to a chain and driven by a DC motor. The amount of movement is controlled by an ultrasonic sensor. When the plate is lowered, the ingredients are placed on the conveyor belt. When the ingredients are placed, the conveyor belt is driven to the next placement point of the ingredients. The amount of movement is controlled using photo interrupters. This process is repeated until all the ingredients are placed on top of each other. The stacked ingredients are sent to the hot sandwich maker. Finally, the lid of the hot sandwich maker is closed and the sandwich is grilled for 5 minutes.
